TECHNICAL FIELD

[0001] The present application belongs to the technical field of cooking utensil manufacturing, and in particular, relates to a material production system. BACKGROUND

[0002] When a cavity to be welded such as a microwave oven or an oven is processed, a worker needs to carry and weld the plate, and the worker has a large workload and low processing efficiency. SUMMARY

[0003] The present application aims to solve one of the problems in the prior art or related art.

[0004] Therefore, the present application provides a material production system, which comprises: a feeding device configured to correct a first cavity to be welded; a top plate welding device arranged on one side of the feeding device, the feeding device being configured to place the first cavity to be welded on the top plate welding device, and the top plate welding device being configured to weld the first cavity to be welded and a top plate to obtain a second cavity to be welded; a material transfer device arranged on one side of the feeding device and configured to transfer the second cavity to be welded; a front plate welding device arranged on one side of the feeding device, the material transfer device being configured to place the second cavity to be welded on the front plate welding device, and the front plate welding device being configured to weld the second cavity to be welded and a front plate to obtain a third cavity to be welded; a feeding device arranged on one side of the front plate welding device; a waveguide welding device arranged on one side of the front plate welding device, the feeding device being configured to place the third cavity to be welded on the waveguide welding device, and the waveguide welding device being configured to weld the third cavity to be welded and a waveguide to obtain a fourth cavity to be welded; and a rear plate welding device arranged on one side of the feeding device, the feeding device being configured to place the fourth cavity to be welded on the rear plate welding device, and the rear plate welding device being configured to weld the fourth cavity to be welded and a rear plate.

[0005] The material production system provided by the present application can use a bending machine to bend the plate to form a U-shaped plate to obtain a first cavity to be welded during the processing of a cooking cavity, then weld the U-shaped plate and a top plate to form a three-dimensional structure with four sides, and then weld the three-dimensional structure with a front plate, a waveguide and a rear plate. Due to the deformation of the plate, the angle between the two adjacent sides of the U-shaped plate may not be a right angle, and it is difficult for the U-shaped plate to tightly contact the front plate when the U-shaped plate is welded with the top plate. The feeding device can correct the first cavity to be welded during the feeding process, so as to ensure that the first cavity to be welded is corrected to a standard cavity structure to be welded. The first cavity to be welded placed in the welding position is not deformed, so that the first cavity to be welded can tightly contact the top plate, avoiding poor welding, and improving the processing precision of the cooking cavity.

[0006] The top plate welding device is used for welding the first to-be-welded cavity and the top plate to obtain a second to-be-welded cavity, the feeding device can place the first to-be-welded cavity at a welding position of the top plate welding device, the mechanical hand assembly can transfer the top plate to the welding position, and the top plate welding device comprises a gas cylinder and a welding machine. The gas cylinder can drive the welding machine to move, and when the welding machine moves to the connection position of the top plate and the first to-be-welded cavity, the welding machine welds the connection position of the top plate and the first to-be-welded cavity.

[0007] The material transfer device can pick up the second to-be-welded cavity at the welding position of the top plate welding device, and then place the second to-be-welded cavity at the front plate welding device. The front plate welding device can weld the front plate and the second to-be-welded cavity to obtain a third to-be-welded cavity.

[0008] The front plate welding device can place the third to-be-welded cavity at the waveguide tube welding device, and the waveguide tube welding device is used for welding the waveguide tube and the third to-be-welded cavity to obtain a fourth to-be-welded cavity.

[0009] The waveguide tube welding device can place the fourth to-be-welded cavity at the rear plate welding device, and the rear plate welding device can weld the rear plate and the fourth to-be-welded cavity to obtain a cooking cavity. The feeding device is used for placing the third to-be-welded cavity at a welding position of the waveguide tube welding device.

[0010] After the waveguide tube welding device welds the waveguide tube and the third to-be-welded cavity, a fourth to-be-welded cavity is obtained. The feeding device can transfer the fourth to-be-welded cavity to the rear plate welding device, and the rear plate welding device can weld the rear plate and the fourth to-be-welded cavity to obtain a cooking cavity.

[0011] Through the above device, the transfer and welding of the material are automatically realized, and the staff does not need to carry and weld the plate, thereby reducing the work load of the staff. Moreover, the automatic production mode can effectively improve the processing efficiency of the cooking cavity.

[0012] In addition, the material production system in the above technical solution provided by the application can also have the following additional technical features:

[0013] In a possible design, the feeding device comprises: a feeding table; first and second correcting assemblies arranged on the feeding table, the first correcting assembly being used for clamping a first side edge in the first to-be-welded cavity, and the second correcting assembly being used for clamping a second side edge in the first to-be-welded cavity; and a first material taking assembly, a part of the first material taking assembly being capable of extending into the first to-be-welded cavity. The part of the first material taking assembly extending into the first to-be-welded cavity adsorbs the first side edge and the second side edge, so that the first material taking assembly can drive the first to-be-welded cavity to move.

[0014] In the design, the first and second correction assemblies are fixed to the feeding table, the first correction assembly is located at the first correction position, and the second correction assembly is located at the second correction position, and the first and second correction assemblies are used to correct the distance between the first and second side edges in the first cavity to be welded.

[0015] During the processing of the cooking cavity, the plate material needs to be bent to form a U-shaped plate, i.e., the first cavity to be welded, and then the U-shaped plate is welded with the side plate to form a three-dimensional structure with four side edges, and then the three-dimensional structure is welded with the front plate, the waveguide tube, and the rear plate.

[0016] Due to the deformation of the plate material, the angle between the two adjacent side edges of the U-shaped plate may not be a right angle, and when the U-shaped plate is welded with the top plate, the U-shaped plate and the front plate are difficult to tightly contact. In the present application, the shape of the first cavity to be welded is corrected by the first and second correction assemblies, so that the first cavity to be welded is corrected to a standard cavity to be welded structure, so as to facilitate subsequent stable welding.

[0017] Specifically, the first cavity to be welded has three side edges, i.e., the first, second, and third side edges, the distance between the clamping positions on the first and second correction assemblies is equal to the length of the third side edge, and when the first and second side edges are clamped by the first and second correction assemblies respectively, the angle between the two adjacent side edges is 90°, thereby ensuring that the first cavity to be welded is corrected to a standard cavity to be welded structure.

[0018] After the first and second correction assemblies correct the shape of the first cavity to be welded, the first material taking assembly needs to transfer the first cavity to be welded, so as to transfer the first cavity to be welded to the welding position.

[0019] Specifically, when the first to-be-welded cavity needs to be transferred, at least part of the first material taking assembly extends into the first to-be-welded cavity, and the part of the first material taking assembly extending into the first to-be-welded cavity adsorbs the first side edge and the second side edge. Since the distance between the first side edge and the second side edge has been adjusted, when the first material taking assembly adsorbs the first side edge and the second side edge, it is ensured that the distance between the first side edge and the second side edge is equal to the length of the third side edge. During the transfer of the first to-be-welded cavity by the first material taking assembly, the first material taking assembly can play a positioning function for the first side edge and the second side edge. Under the support of the first material taking assembly, the distance between the first side edge and the second side edge is not prone to decrease, and under the adsorption of the first material taking assembly, the distance between the first side edge and the second side edge is not prone to increase. During the transfer process, the first to-be-welded cavity always maintains the standard to-be-welded cavity structure. It is ensured that the first to-be-welded cavity placed in the to-be-welded position does not deform, so that the first to-be-welded cavity can be closely attached to the side plate, avoiding the occurrence of poor welding, and being conducive to improving the machining precision of the cooking cavity.

[0020] By transferring the first to-be-welded cavity through the first material taking assembly, automatic handling of the first to-be-welded cavity is realized, saving the work amount of the staff for handling the first to-be-welded cavity.

[0021] By correcting the shape of the first to-be-welded cavity through the first correction assembly and the second correction assembly, it is ensured that the first to-be-welded cavity is a standard structure without deformation, and the staff does not need to pull the deformed first to-be-welded cavity, further saving the work amount of the staff.

[0022] In a possible design, the first correction assembly comprises: a first power part arranged on the feeding table; and a first clamping plate and a second clamping plate arranged on the first power part, the first power part being configured to drive the first clamping plate and the second clamping plate to approach or move away from each other.

[0023] In this design, the first power part can drive the first clamping plate and the second clamping plate to move, so that the first clamping plate and the second clamping plate approach or move away from each other.

[0024] Before feeding, the first power part drives the first clamping plate and the second clamping plate to move away from each other, and the first clamping plate and the second clamping plate have a gap therebetween, and the first side edge in the first to-be-welded cavity extends into the gap between the first clamping plate and the second clamping plate. The first power part drives the first clamping plate and the second clamping plate to approach each other, and if the first side edge deforms, the shape of the first side edge will be corrected by the first clamping plate and the second clamping plate.

[0025] The second correcting assembly comprises: a second power unit arranged on the feeding table; and a third clamping plate and a fourth clamping plate arranged on the second power unit, and the second power unit is configured to drive the third clamping plate and the fourth clamping plate to move towards or away from each other.

[0026] The second power unit is configured to drive the third clamping plate and the fourth clamping plate to move, so that the third clamping plate and the fourth clamping plate move towards or away from each other.

[0027] Before feeding, the second power unit drives the third clamping plate and the fourth clamping plate to move away from each other, and a gap is formed between the third clamping plate and the fourth clamping plate, and the second side edge in the first to-be-welded cavity extends into the gap between the third clamping plate and the fourth clamping plate. The second power unit drives the third clamping plate and the fourth clamping plate to move towards each other, and if the second side edge is deformed, the shape of the second side edge is corrected by the third clamping plate and the fourth clamping plate.

[0028] In a possible design, the first correcting assembly further comprises at least one first guiding assembly arranged on the first clamping plate and / or the second clamping plate, and the first guiding assembly is configured to guide the first side edge to extend into the first clamping plate and the second clamping plate.

[0029] In this design, the first guiding assembly is arranged on the first clamping plate and / or the second clamping plate, and the first guiding assembly can guide the first side edge that needs to extend into the first clamping plate and the second clamping plate.

[0030] The maximum distance between the first clamping plate and the second clamping plate is limited, and in the process of placing the first to-be-welded cavity on the feeding table, the first side edge may not be able to extend into the first clamping plate and the second clamping plate due to a large deformation of the adjacent two side edges in the first to-be-welded cavity. By adding the first guiding assembly, the first guiding assembly guides the first side edge to extend into the first clamping plate and the second clamping plate. By adding the first guiding assembly, the first side edge can be automatically extended into the first clamping plate and the second clamping plate without manual movement of the first side edge by the staff.

[0031] The second correcting assembly further comprises at least one second guiding assembly arranged on the third clamping plate and / or the fourth clamping plate, and the second guiding assembly is configured to guide the second side edge to extend into the third clamping plate and the fourth clamping plate.

[0032] The second guiding assembly is arranged on the third clamping plate and / or the fourth clamping plate, and the second guiding assembly can guide the second side edge that needs to extend into the third clamping plate and the fourth clamping plate.

[0033] The maximum distance between the third clamping plate and the fourth clamping plate is limited. During the process of placing the first cavity to be welded on the upper table, the second side edge cannot be inserted between the third clamping plate and the fourth clamping plate due to the large deformation of the adjacent two side edges in the first cavity to be welded. The second guide assembly is added, which plays a guiding role on the second side edge, and facilitates the second side edge to be inserted between the third clamping plate and the fourth clamping plate under the guidance of the second guide assembly. By adding the second guide assembly, the staff does not need to manually move the second side edge, and the second side edge is automatically inserted between the third clamping plate and the fourth clamping plate.

[0034] In a possible design, the first guide assembly comprises: a first guide plate arranged on the first clamping plate; and a second guide plate arranged on the second clamping plate, wherein the distance between the first guide plate and the second guide plate increases in a direction away from the first clamping plate and the second clamping plate.

[0035] In this design, a guide plate is arranged on the first clamping plate, and a second guide plate is arranged on the second clamping plate. From bottom to top, the distance between the first guide plate and the second guide plate gradually increases, that is, a flared structure is formed between the first guide plate and the second guide plate. Since the distance between the first guide plate and the second guide plate at the upper part is large, the first side edge is easily inserted between the first guide plate and the second guide plate. In the direction of the first side edge insertion, the distance between the first guide plate and the second guide plate gradually decreases. Under the guidance of the first guide plate and the second guide plate, the first side edge is gradually guided between the first clamping plate and the second clamping plate, so that the first clamping plate and the second clamping plate can correct the shape of the first side edge, which is beneficial to improve the stability of the feeding process.

[0036] The second guide assembly comprises: a third guide plate arranged on the third clamping plate; and a fourth guide plate arranged on the fourth clamping plate, wherein the distance between the third guide plate and the fourth guide plate increases in a direction away from the third clamping plate and the fourth clamping plate.

[0037] The third guide plate is arranged on the third clamping plate, and the fourth guide plate is arranged on the fourth clamping plate. From bottom to top, the distance between the third guide plate and the fourth guide plate gradually increases, that is, a flared structure is formed between the third guide plate and the fourth guide plate. Since the distance between the third guide plate and the fourth guide plate at the upper part is large, the second side edge is easily inserted between the third guide plate and the fourth guide plate. In the direction of the second side edge insertion, the distance between the third guide plate and the fourth guide plate gradually decreases. Under the guidance of the third guide plate and the fourth guide plate, the second side edge is gradually guided between the third clamping plate and the fourth clamping plate, so that the third clamping plate and the fourth clamping plate can correct the shape of the second side edge, which is beneficial to improve the stability of the feeding process.

[0038] In one possible design, the first guiding assembly further includes: a first mounting hole arranged on the first clamping plate; a fourth waist-shaped hole arranged on the first guiding plate; a first locking member penetrating through the first mounting hole and the fourth waist-shaped hole to lock the first guiding plate to the first clamping plate; a second mounting hole arranged on the second clamping plate; a fifth waist-shaped hole arranged on the second guiding plate; and a second locking member penetrating through the second mounting hole and the fifth waist-shaped hole to lock the second guiding plate to the second clamping plate.

[0039] In this design, the first locking member can penetrate through the fourth waist-shaped hole and the first mounting hole to lock the first guiding plate to the first clamping plate. Since the waist-shaped hole is arranged on the first guiding plate, the position of the first guiding plate on the first clamping plate can be adjusted before the first locking member is locked to the first guiding plate, so as to facilitate adjustment of the first guiding plate to a position suitable for guiding the first side edge.

[0040] Similarly, the second locking member can penetrate through the fifth waist-shaped hole and the second mounting hole to lock the second guiding plate to the second clamping plate. Since the waist-shaped hole is arranged on the second guiding plate, the position of the second guiding plate on the second clamping plate can be adjusted before the second locking member is locked to the second guiding plate, so as to facilitate adjustment of the second guiding plate to a position suitable for guiding the first side edge.

[0041] In one possible design, the second guiding assembly further includes: a third mounting hole arranged on the third clamping plate; a sixth waist-shaped hole arranged on the third guiding plate; a third locking member penetrating through the third mounting hole and the sixth waist-shaped hole to lock the third guiding plate to the third clamping plate; a fourth mounting hole arranged on the fourth clamping plate; a seventh waist-shaped hole arranged on the fourth guiding plate; and a fourth locking member penetrating through the fourth mounting hole and the seventh waist-shaped hole to lock the fourth guiding plate to the fourth clamping plate.

[0042] In this design, the third locking member can penetrate through the sixth waist-shaped hole and the third mounting hole to lock the third guiding plate to the third clamping plate. Since the waist-shaped hole is arranged on the third guiding plate, the position of the third guiding plate on the third clamping plate can be adjusted before the third locking member is locked to the third guiding plate, so as to facilitate adjustment of the third guiding plate to a position suitable for guiding the second side edge.

[0043] Similarly, the fourth locking member can penetrate through the seventh waist-shaped hole and the fourth mounting hole to lock the fourth guiding plate to the fourth clamping plate. Since the waist-shaped hole is arranged on the fourth guiding plate, the position of the fourth guiding plate on the fourth clamping plate can be adjusted before the fourth locking member is locked to the fourth guiding plate, so as to facilitate adjustment of the fourth guiding plate to a position suitable for guiding the second side edge.

[0044] In one possible design, the feeding device further includes: a first positioning body arranged on the feeding table; and a pushing assembly configured to push the first to-be-welded cavity towards the first positioning body.

[0045] In the design, the first positioning body is arranged on the feeding table, and the pushing assembly can push the first to-be-welded cavity, so that the first to-be-welded cavity is pushed to abut against the first positioning body, thereby realizing positioning of the first to-be-welded cavity.

[0046] When the first to-be-welded cavity is placed on the feeding table, although the first and second correcting assemblies can correct the shape of the first to-be-welded body, the first to-be-welded cavity can deviate from the feeding position, so that the first material taking assembly can not accurately move the first to-be-welded cavity. The first positioning body serves as a reference part, the pushing assembly pushes the first to-be-welded cavity towards the first positioning body, and when the first to-be-welded cavity contacts the first positioning body, it indicates that the first to-be-welded cavity is moved into position, and at this time, the first material taking assembly can accurately take away the first to-be-welded cavity.

[0047] In a possible design, the pushing assembly comprises a third power part arranged on the feeding table, and a pushing piece arranged on the third power part, wherein the third power part is configured to drive the pushing piece to move, so as to push the first to-be-welded cavity.

[0048] In the design, the third power part is mounted on the feeding table, and the third power part can drive the pushing piece to move, so that the pushing piece pushes the first to-be-welded cavity towards the first positioning body.

[0049] When the first side edge extends between the first and second clamping plates, and the second side edge extends between the third and fourth clamping plates, the third power part pushes the first to-be-welded cavity, and when the first to-be-welded cavity contacts the first positioning body, it indicates that the first to-be-welded cavity is moved into position, and at this time, the first material taking assembly can accurately take away the first to-be-welded cavity.

[0050] In a possible design, the feeding device further comprises first and second positioning pins arranged on the feeding table, wherein the first side edge is provided with a first insertion hole, and the second side edge is provided with a second insertion hole, and in the case that the first to-be-welded cavity is pushed to contact the first positioning body, the first and second positioning pins are respectively inserted into the first and second insertion holes.

[0051] In the design, when the first cavity to be welded moves to the case of contacting the first positioning body, it indicates that the first cavity to be welded is moved to position. When the first cavity to be welded is moved to position, the first positioning pin is inserted into the first insertion hole of the first side edge, and the second positioning pin is inserted into the second insertion hole of the second side edge. The first positioning pin and the second positioning pin can keep the first cavity to be welded as a regular cavity shape, avoid the first cavity to be welded from being deformed again due to abnormality of the first correction assembly and the second correction assembly, and ensure that the first material taking assembly can transfer the regular first cavity to be welded. By arranging the first positioning pin and the second positioning pin, the stability of the first cavity to be welded in keeping regular shape is improved.

[0052] When the first cavity to be welded is not moved to position, the first positioning pin and the second positioning pin are in a retracted state, and when the first cavity to be welded is moved to position, the first positioning pin and the second positioning pin are extended out of the feeding table.

[0053] In a possible design, the feeding device further comprises a first sensor arranged on the feeding table, and the first sensor is configured to detect the position of the first cavity to be welded, so that the first positioning pin and the second positioning pin act according to the detection signal of the first sensor.

[0054] In the design, the first sensor can detect the position of the first cavity to be welded, and the first positioning pin and the second positioning pin act according to the detection signal of the first sensor. When the first sensor does not detect that the first cavity to be welded is moved to position, the first positioning pin and the second positioning pin do not act, so as to avoid interference of the first positioning pin and the second positioning pin to the movement of the first cavity to be welded. When the first cavity to be welded is moved to position, the first sensor detects that the first cavity to be welded is moved to position, and the first positioning pin and the second positioning pin act and are respectively inserted into the first insertion hole and the second insertion hole.

[0055] In a possible design, the first material taking assembly comprises a first guide rail assembly, a fourth power unit arranged on the first guide rail assembly, the first guide rail assembly being configured to drive the fourth power unit to move, a fifth power unit arranged on the fourth power unit, the fourth power unit being configured to drive the fifth power unit to ascend or descend, and a sixth adsorption assembly and a seventh adsorption assembly arranged at two ends in the axial direction of the fifth power unit, the fifth power unit being configured to drive the sixth adsorption assembly and the seventh adsorption assembly to extend into or extend out of the first cavity to be welded, the sixth adsorption assembly being configured to adsorb the first side edge, and the seventh adsorption assembly being configured to adsorb the second side edge.

[0056] In the design, when the first to-be-welded cavity needs to be transferred, the first guide rail assembly drives the fourth power part to move above the first to-be-welded cavity, the fourth power part drives the fifth power part to descend, and the fifth power part drives the sixth adsorption assembly and the seventh adsorption assembly to extend into the first to-be-welded cavity. The sixth adsorption assembly adsorbs the first side edge, and the seventh adsorption assembly adsorbs the second side edge. Under the adsorption action of the sixth adsorption assembly and the seventh adsorption assembly, the distance between the first side edge and the second side edge is ensured not to change during the transfer of the first to-be-welded cavity.

[0057] After the sixth adsorption assembly adsorbs the first side edge and the seventh adsorption assembly adsorbs the second side edge, the first correction assembly stops clamping the first side edge, the second correction assembly stops clamping the second side edge, the fourth power part drives the fifth power part to ascend, and the second guide rail assembly drives the fourth power part to move, thereby realizing the feeding process.

[0058] In a possible design, the sixth adsorption assembly comprises: a first mounting frame arranged on the fifth power part; and a sixth power part arranged on the first mounting frame; and two first adsorption members arranged on the sixth power part, and the sixth power part is configured to drive the two first adsorption members to approach or move away from each other.

[0059] In the design, the fifth power part can drive the first mounting frame to move laterally, the sixth power part is arranged on the first mounting frame, and the first mounting frame can drive the sixth power part to move, so that the sixth power part can extend into or out of the first to-be-welded cavity.

[0060] The two first adsorption members are arranged on the sixth power part, and the sixth power part can drive the two first adsorption members to move, so that the two first adsorption members can approach or move away from each other.

[0061] When the first to-be-welded cavity needs to be transferred, the fifth power part drives the sixth adsorption assembly to extend into the first to-be-welded cavity, and the sixth power part drives the two first adsorption members to move away from each other, so that the two first adsorption members adsorb the first side edge and the second side edge, respectively.

[0062] The seventh adsorption assembly comprises: a second mounting frame arranged on the fifth power part; a seventh power part arranged on the second mounting frame; and two second adsorption members arranged on the seventh power part, and the seventh power part is configured to drive the two second adsorption members to approach or move away from each other.

[0063] The fifth power part can drive the second mounting frame to move laterally, the seventh power part is arranged on the second mounting frame, and the second mounting frame can drive the seventh power part to move, so that the seventh power part can extend into or out of the first to-be-welded cavity.

[0064] Two second suction accessories are installed on the seventh power unit, and the seventh power unit can drive the two second suction accessories to move so that the two second suction accessories can approach or move away from each other.

[0065] When the first to-be-welded cavity needs to be transferred, the fifth power unit drives the seventh suction assembly to extend into the first to-be-welded cavity, and the seventh power unit drives the two second suction accessories to move away from each other, so that the two second suction accessories respectively suck the first side edge and the second side edge.

[0066] The sixth suction assembly and the seventh suction assembly extend into the first to-be-welded cavity on both sides of the first to-be-welded cavity, so that the first to-be-welded cavity is balanced in force, and the first to-be-welded cavity is not easy to deviate when the first to-be-welded cavity is transferred, thereby improving the stability in the feeding process.

[0067] In a possible design, the first suction accessory includes a magnetic suction element or a suction nozzle.

[0068] In this design, the first suction accessory can be a magnetic suction element, and the first suction accessory is magnetically attracted to the first side edge and the second side edge. The first suction accessory can also be a suction nozzle.

[0069] The second suction accessory can be a magnetic suction element, and the second suction accessory is magnetically attracted to the first side edge and the second side edge. The second suction accessory can also be a suction nozzle.

[0070] In a possible design, the fourth power unit includes a mounting plate arranged on the first guide rail assembly, a second air cylinder arranged on the mounting plate, a third air cylinder arranged on the second air cylinder, the second air cylinder being configured to drive the third air cylinder to ascend or descend, and a support plate arranged on the third air cylinder, the fifth power unit being arranged on the support plate, and the third air cylinder being configured to drive the support plate to ascend or descend.

[0071] In this design, the mounting plate is arranged on the first guide rail assembly, the second air cylinder is arranged on the mounting plate, and the mounting plate bears the second air cylinder. The third air cylinder is arranged on the second air cylinder, and the second air cylinder can drive the third air cylinder to ascend or descend. The support plate is arranged on the third air cylinder, and the fifth power unit is arranged on the support plate. The third air cylinder can drive the support plate and the fifth power unit to ascend or descend.

[0072] When the piston rod of the second air cylinder extends, the third air cylinder, the support plate and the fifth power unit descend, at this time, the support plate and the fifth power unit are in a first-stage descent. When the piston rod of the third air cylinder extends, the support plate and the fifth power unit descend, at this time, the support plate and the fifth power unit are in a second-stage descent. By arranging the combined structure of the second air cylinder and the third air cylinder, the support plate and the fifth power unit have two strokes, and the convenience of feeding and taking can be improved.

[0073] In addition, since the second cylinder and the third cylinder form two strokes, the piston rods of the second cylinder and the third cylinder can be extended during the loading of the first loading assembly, so that the adsorbed first to-be-welded cavity is placed at the descending process position. After the first to-be-welded cavity is placed, the piston rod of the second cylinder or the third cylinder is retracted, so that the support plate and the fifth power part are separated from the loading station, that is, the two-stroke descending and single-stroke ascending. By shortening the movement stroke, the loading efficiency is effectively improved.

[0074] In a possible design, the first loading assembly further includes an eighth adsorption assembly arranged on the fourth power part, and the eighth adsorption assembly is configured to adsorb the first to-be-welded cavity.

[0075] In this design, the eighth adsorption assembly is arranged on the fourth power part, and the fourth power part can drive the eighth adsorption assembly to ascend or descend. The eighth adsorption assembly can adsorb the outer surface of the first to-be-welded cavity, so that the first to-be-welded cavity is prevented from separating from the first loading assembly during the loading process, and the stability during the loading process is improved.

[0076] In a possible design, the material transfer device includes a first adsorption assembly configured to adsorb and move the second to-be-welded cavity, and a support assembly arranged on the first adsorption assembly. When the first adsorption assembly adsorbs the second to-be-welded cavity, a part of the support assembly extends into the second to-be-welded cavity, and the support assembly is configured to push the inner wall of the second to-be-welded cavity.

[0077] In this design, when the second to-be-welded cavity needs to be transferred, the first adsorption assembly moves the support assembly to the vicinity of the second to-be-welded cavity, and a part of the support assembly extends into the second to-be-welded cavity.

[0078] The second to-be-welded cavity can have a three-dimensional structure with four sides, and the second to-be-welded cavity needs to be welded with the front plate and the rear plate to form a complete cooking cavity.

[0079] When the second cavity to be welded needs to be welded with the front plate, it is necessary to ensure that the two adjacent sides in the second cavity to be welded are at right angles, so that the second cavity to be welded can be closely attached to the front plate. Before welding the front plate, the second cavity to be welded can be deformed, resulting in an acute or obtuse angle between the two adjacent sides. A part of the support assembly extending into the second cavity to be welded can push the two opposite inner walls in the second cavity to be welded. With the pushing of the support assembly, the two opposite inner walls in the second cavity to be welded move away from each other. With the two inner walls moving away from each other, the included angle between the two adjacent sides in the second cavity to be welded also changes, and when the support assembly moves to the limit position, the included angle between the two adjacent sides in the second cavity to be welded is at right angles. The first adsorption assembly adsorbs the outer side wall of the second cavity to be welded, so that the second cavity to be welded is not easy to shake, which is beneficial to the pushing of the inner wall of the second cavity to be welded by the support assembly.

[0080] The movement of the support assembly to the limit position refers to that, for the second cavity to be welded with the two adjacent sides at right angles, a part of the support assembly located in the second cavity to be welded is in contact with the two opposite inner walls.

[0081] The first adsorption assembly can move the second cavity to be welded to the welding position. During the movement of the second cavity to be welded by the first adsorption assembly, the support assembly supports the two adjacent inner walls in the second cavity to be welded, so that the two adjacent sides in the second cavity to be welded placed in the welding position are at right angles. When the second cavity to be welded is welded with the front plate, the second cavity to be welded can be closely attached to the front plate, avoiding poor welding and improving the processing precision of the cooking cavity.

[0082] The first adsorption assembly transfers the second cavity to be welded, realizing automatic handling of the second cavity to be welded and saving the workload of the staff in handling the second cavity to be welded.

[0083] The support assembly operates the deformed second cavity to be welded, ensuring that the second cavity to be welded in the welding position is a standard structure without deformation, and the staff does not need to pull the deformed second cavity to be welded, further saving the workload of the staff. Moreover, the first adsorption assembly automatically pulls the second cavity to be welded, so that the second cavity to be welded can be accurately placed in the welding position, which is beneficial to further improving the welding precision of the second cavity to be welded and the front plate.

[0084] In a possible design, the support assembly comprises: a fixed plate arranged on the first adsorption assembly; a power member arranged on the fixed plate; first and second support members arranged on the power member, and the power member is configured to drive the first and second support members to move, so that the first and second support members push the two opposite inner walls in the second cavity to be welded.

[0085] In this design, the fixed plate is installed on the first adsorption assembly, the first adsorption assembly can drive the fixed plate to move, and the power component is installed on the fixed plate, so that the fixed plate can drive the power component to move. The first support component and the second support component are installed on the power component, and the power component can drive the first support component and the second support component to approach or move away from each other.

[0086] When the second cavity to be welded needs to be transferred, the first adsorption assembly drives the fixed plate to move, so that the fixed plate drives the power component, the first support component and the second support component to extend into the second cavity to be welded. The first adsorption assembly adsorbs one side of the outer side wall of the second cavity to be welded, and the adsorbed outer side wall serves as a reference part. When the first support component and the second support component push the two opposite inner walls in the second cavity to be welded, the second cavity to be welded is not easy to move relative to the first adsorption assembly.

[0087] When the first support component and the second support component push the two opposite inner walls in the second cavity to be welded, the two opposite inner walls gradually move away from each other. As the two inner walls move away from each other, the included angle between the two adjacent sides in the second cavity to be welded also changes. When the support assembly moves to the limit position, the included angle between the two adjacent sides in the second cavity to be welded is a right angle. When the second cavity to be welded is welded with the front plate, the second cavity to be welded can be in close contact with the front plate, so as to avoid poor welding and improve the processing precision of the cooking cavity.

[0088] In a possible design, the power component includes: a first cylinder; a first connecting plate provided on the first cylinder, and the first support component is provided on the first connecting plate; and a second connecting plate provided on the first cylinder, and the second support component is provided on the second connecting plate.

[0089] In this design, the first cylinder can drive the first connecting plate and the second connecting plate to move, so that the first connecting plate drives the first support component to move, and the second connecting plate drives the second support component to move.

[0090] The number of first cylinders can be two, one first cylinder is connected with the first connecting plate, and the other first cylinder is connected with the second connecting plate.

[0091] In order to ensure that the first support component and the second support component can stably push the inner walls of the second cavity to be welded, it is necessary to set the first support component and the second support component to have a large contact area with the inner walls of the second cavity to be welded. The assembly difficulty of the large-volume first support component and the second support component with the first cylinder is large, and therefore a first connecting plate can be arranged between the first cylinder and the first support component as an intermediate component to improve the assembly convenience of the power component and the first support component. Similarly, a second connecting plate is arranged between the first cylinder and the second support component.

[0092] In a possible design, the first support member is detachably connected to the first connecting plate; and / or the second support member is detachably connected to the second connecting plate.

[0093] In this design, when the first connecting plate or the first support member is damaged, the first support member can be detached from the first connecting plate, so that the first connecting plate or the first support member can be replaced individually, which is conducive to reducing the maintenance cost.

[0094] Similarly, when the second connecting plate or the second support member is damaged, the second support member can be detached from the second connecting plate, so that the second connecting plate or the second support member can be replaced individually, which is conducive to reducing the maintenance cost.

[0095] In a possible design, the support assembly further comprises: a first waist-shaped hole provided on the first connecting plate; a first through hole provided on the first support member; a first locking member, the first locking member passing through the first waist-shaped hole and the first through hole to lock the first support member to the first connecting plate; a second waist-shaped hole provided on the second connecting plate; a second through hole provided on the second support member; and a second locking member, the second locking member passing through the second waist-shaped hole and the second through hole to lock the second support member to the second connecting plate.

[0096] In this design, the first connecting plate is provided with the first waist-shaped hole, the first support member is provided with the first through hole, and the first locking member can pass through the first waist-shaped hole and the first through hole. Before the first locking member is locked to the first connecting plate, the first waist-shaped hole and the first locking member can move relatively, so that the relative positions of the first support member and the first connecting plate can be adjusted, so as to adjust the first support member to a position suitable for supporting the inner wall of the second cavity to be welded.

[0097] The second connecting plate is provided with the second waist-shaped hole, the second support member is provided with the second through hole, and the second locking member can pass through the second waist-shaped hole and the second through hole. Before the second locking member is locked to the second connecting plate, the second waist-shaped hole and the second locking member can move relatively, so that the relative positions of the second support member and the second connecting plate can be adjusted, so as to adjust the second support member to a position suitable for supporting the inner wall of the second cavity to be welded.

[0098] In a possible design, the thickness of the first connecting plate is greater than the thickness of the first support member; and / or the thickness of the second connecting plate is greater than the thickness of the second support member.

[0099] In this design, the thickness of the first connecting plate is greater than the thickness of the first support member, so that the first connecting plate is not easy to be broken, and the first connecting plate can stably support the first support member.

[0100] The thickness of the second connecting plate is greater than the thickness of the second support, so that the second connecting plate is not easy to break, and the second connecting plate can stably support the second support.

[0101] In a possible design, the fixing plate comprises: a first plate body, which is arranged on the first adsorption assembly; and a second plate body, wherein the power member is arranged on the second plate body, and the width of the second plate body is greater than the width of the first plate body.

[0102] In this design, the first plate body is mounted on the first adsorption assembly, and the second plate body is connected with the power member. Since the width of the second plate body is greater than the width of the first plate body, the second plate body has higher structural stability, thereby ensuring the connection stability of the second plate body and the power member.

[0103] By reducing the width of the first plate body, the weight of the fixing plate is reduced, and the overall weight of the support assembly is reduced, which is beneficial to improve the operation stability of the material transfer device.

[0104] In a possible design, the support assembly is detachably connected to the first adsorption assembly.

[0105] In this design, the support assembly can be detached from the first adsorption assembly, so that when the support assembly or the first adsorption assembly is damaged, the support assembly can be detached from the first adsorption assembly, thereby facilitating the separate maintenance or replacement of the support assembly or the first adsorption assembly, and the maintenance cost of the material transfer device is reduced.

[0106] In a possible design, the first adsorption assembly comprises: a suction member, which is used to suck the second to-be-welded cavity; and the support assembly is arranged on the suction member.

[0107] In this design, the support assembly is mounted on the suction member, and the suction member can adsorb the second to-be-welded cavity, so that the first adsorption assembly can drive the second to-be-welded cavity to move. The suction member is mounted on the manipulator, and the manipulator has a plurality of rotating shafts, so that the manipulator can flexibly drive the suction member and the support assembly to move.

[0108] When the second to-be-welded cavity needs to be transferred, the manipulator first drives the support assembly to extend into the second to-be-welded cavity, and then adjusts the position of the suction member, so that the support assembly can support the inner wall of the second to-be-welded cavity, and the suction member is in contact with the outer wall of the second to-be-welded cavity. By driving the support assembly and the suction member to move through the manipulator, the stability during the feeding process is improved.

[0109] In a possible design, the suction member is rotationally connected to the manipulator.

[0110] In the design, the suction member can rotate relative to the manipulator, so that the manipulator can drive the suction member to rotate. The manipulator can adjust the relative position of the suction member and the second cavity to be welded by driving the suction member to rotate, so that the support member can be conveniently inserted into the second cavity to be welded and the position of the suction member for sucking the second cavity to be welded can be adjusted, and the flexibility in the feeding process is improved. The position of the second cavity to be welded does not need to be adjusted by the staff.

[0111] In a possible design, the suction member comprises a bearing plate, and the support assembly is arranged on the bearing plate; and at least two suction parts are arranged on the bearing plate, and the suction parts are used for sucking the second cavity to be welded.

[0112] In the design, the bearing plate bears the support assembly and the at least two suction parts, and the stability of the suction member for sucking the second cavity to be welded can be improved by increasing the number of the suction parts, so that the suction member and the second cavity to be welded are prevented from being separated, and the stability in the process of transferring the second cavity to be welded is improved.

[0113] In a possible design, the suction part comprises a connecting rod arranged on the bearing plate, the connecting rod is provided with a sliding cavity, an elastic member is arranged in the sliding cavity, a sliding rod is slidably connected to the sliding cavity, the sliding rod is in abutment with the elastic member, and a suction nozzle is arranged on the sliding rod.

[0114] In the design, the connecting rod is internally provided with the sliding cavity, the sliding rod can slide in the sliding cavity, so that the sliding rod can be inserted into or extended out of the sliding cavity, and the length of the sliding rod extended out of the sliding cavity can be adjusted.

[0115] The elastic member is arranged in the sliding cavity, the sliding rod is in contact with the elastic member, and the elastic member is compressed when the sliding rod moves into the sliding cavity.

[0116] The suction nozzle is arranged on the sliding rod, the suction nozzle can be adsorbed on the outer surface of the second cavity to be welded, and the sliding rod can slide relative to the connecting rod when the suction assembly sucks the second cavity to be welded, so that the suction nozzle plays a buffering role and is prevented from being damaged due to collision with the second cavity to be welded, and the structural stability of the first adsorption assembly is improved.

[0117] In a possible design, the suction member further comprises a locking hole arranged on the bearing plate, and the suction part is detachably connected to the locking hole.

[0118] In the design, the suction part can be detached from the locking hole, so that the suction part can be detached from the bearing plate, and the suction part can be individually maintained and replaced when the suction part is damaged, and the maintenance cost of the suction member is reduced.

[0119] In a possible design, the number of the locking holes is greater than the number of the suction parts.

[0120] In the design, the suction part can be connected with any locking hole on the bearing plate, so that the position of the suction part on the bearing plate can be adjusted. The suction part can be adjusted to a position suitable for sucking the second cavity to be welded. For example, when the second cavity to be welded has a through-hole structure, the position of the suction part can be adjusted to avoid the through-hole structure, which is beneficial to improve the adsorption stability of the suction part to the second cavity to be welded.

[0121] In a possible design, the front plate welding device comprises a first rack, a first transfer assembly arranged on the first rack and configured to drive the second cavity to be welded to move to the first welding position, a first positioning assembly arranged on the transfer assembly and configured to position the second cavity to be welded, a second transfer assembly arranged on the first rack and configured to drive the front plate to move to the first welding position, a second positioning assembly arranged on the first rack and located at the first welding position, and configured to position the front plate, and a first welding assembly arranged on the first rack and configured to weld the second cavity to be welded and the front plate.

[0122] In the design, the first transfer assembly can drive the second cavity to be welded to move, and the first positioning assembly arranged on the first transfer assembly can position the second cavity to be welded. Under the positioning action of the first positioning assembly, the second cavity to be welded is less likely to move relative to the first transfer assembly, so that the first positioning assembly can stably drive the second cavity to be welded to move to the first welding position.

[0123] The second cavity to be welded can have a three-dimensional structure with four sides, and the cavity to be welded needs to be welded with the front plate and the rear plate to form a complete cooking cavity.

[0124] When the second cavity to be welded and the front plate need to be welded, the first transfer assembly drives the second cavity to be welded to move to the first welding position, and the first positioning assembly can position the second cavity to be welded not only during the movement, but also when the second cavity to be welded moves to the first welding position. During the movement and welding, the second cavity to be welded is less likely to move relative to the first transfer assembly, which is beneficial to ensure the stability and accuracy of the welding process.

[0125] The second transfer assembly can drive the front plate to move to the first welding position, so that the front plate can be automatically transferred to the first welding position. The first welding assembly located near the first welding position can weld the front plate and the second cavity to be welded, and the welding process is automatically completed.

[0126] The second positioning assembly is arranged at the first welding position and can position the front plate moved to the first welding position, so that the front plate is accurately positioned to the position to be welded. Moreover, under the positioning action of the second positioning assembly, the front plate is not prone to shaking, so that the front plate and the second cavity to be welded can stably complete the welding process.

[0127] The first transfer assembly drives the second cavity to be welded to move, and the second transfer assembly drives the front plate to move, thereby automatically transferring the second cavity to be welded and the front plate, saving the work of workers to carry the second cavity to be welded and the front plate.

[0128] The first positioning assembly positions the second cavity to be welded, and the second positioning assembly positions the front plate, thereby automatically transferring the second cavity to be welded and the front plate, saving the work of workers to position the second cavity to be welded and the front plate. Moreover, compared with the manual positioning mode, the positioning mode of the mechanical structure can improve the positioning accuracy, the first welding assembly can accurately weld the second cavity to be welded and the front plate, avoiding the occurrence of poor welding, and is beneficial to improve the processing precision of the cooking cavity.

[0129] In a possible design, the first positioning assembly comprises: a first support rib; and a first driving member arranged at the first transfer assembly and configured to drive the first support rib to move so that the first support rib abuts against the plurality of inner walls of the second cavity to be welded.

[0130] In this design, when the second cavity to be welded is placed on the first transfer assembly, the first driving member drives the first support rib to move, so that the first support rib can contact the plurality of inner walls of the second cavity to be welded.

[0131] The second cavity to be welded has four side walls, and the first driving member can drive the first support rib to contact the four side walls of the second cavity to be welded. The first support rib supports the inner walls of the second cavity to be welded, thereby fixing the second cavity to be welded to the first transfer assembly.

[0132] Since the first support rib can contact the plurality of side walls of the second cavity to be welded, the first support rib can push the plurality of side walls of the second cavity to be welded, thereby adjusting the position of the second cavity to be welded on the first transfer assembly, achieving the function of positioning the second cavity to be welded. When the first transfer assembly drives the second cavity to be welded to move to the first welding position, the position of the second cavity to be welded does not need to be adjusted, which is beneficial to accurately weld the second cavity to be welded and the front plate.

[0133] When the second cavity to be welded is not supported by the front plate, the second cavity to be welded is prone to deformation, i.e., the included angle between two adjacent side walls in the second cavity to be welded can be an acute angle or an obtuse angle. The first support rib supports the plurality of side walls in the second cavity to be welded, so that the second cavity to be welded is supported as a regular cavity structure, i.e., the included angle between two adjacent side walls in the second cavity to be welded is 90°. When the second cavity to be welded is welded with the front plate, the second cavity to be welded can be in close contact with the front plate, so that poor welding is avoided, and the machining precision of the cooking cavity is improved.

[0134] The first support rib supports the second cavity to be welded, so that the second cavity to be welded is not prone to shaking relative to the first transfer assembly, and the stability of transferring the second cavity to be welded is improved.

[0135] In a possible design, the second cavity to be welded includes a first inner wall, a second inner wall, a third inner wall and a fourth inner wall; the first driving member includes a first sub-driving part and a second sub-driving part; the first support rib includes a first support part and a second support part connected with each other, and is arranged at the first sub-driving part, and the first support part and the second support part are respectively used for abutting against the first inner wall and the second inner wall; a third support part and a fourth support part connected with each other, and are arranged at the second sub-driving part, and the third support part and the fourth support part are respectively used for abutting against the third inner wall and the fourth inner wall.

[0136] In this design, the first support rib includes the first support part, the second support part, the third support part and the fourth support part, and the first support part, the second support part, the third support part and the fourth support part are respectively used for contacting the first inner wall, the second inner wall, the third inner wall and the fourth inner wall in the second cavity to be welded. The first support part and the second support part are connected with each other, and the first support part and / or the second support part is arranged at the first sub-driving part, so that the first sub-driving part can drive the first support part and the second support part to move. The third support part and the fourth support part are connected with each other, and the third support part and / or the fourth support part is arranged at the second sub-driving part, so that the second sub-driving part can drive the third support part and the fourth support part to move.

[0137] The axial directions of the first sub-driving part and the second sub-driving part can be perpendicular to each other. For example, the first sub-driving part drives the first support part to push the first inner wall, and as the first inner wall is pushed, the third inner wall contacts the third support part. The second sub-driving part drives the fourth support part to push the fourth inner wall, and as the fourth inner wall is pushed, the second inner wall contacts the first support plate. In this way, the positioning and structure correction of the second cavity to be welded are realized.

[0138] Of course, in other designs, four sub-driving parts can be arranged to respectively drive the first support part, the second support part, the third support part and the fourth support part to move.

[0139] In a possible design, the second positioning assembly comprises: a first positioning part, a second positioning part configured to push the front plate to move towards the first positioning part, a third positioning part and a fourth positioning part arranged on the first rack and configured to push the front plate, and the first positioning part, the second positioning part, the third positioning part and the fourth positioning part are configured to contact different sides of the front plate.

[0140] In this design, the second transfer assembly moves the front plate to the first welding position, and the front plate can be placed on top of the second welding cavity at the feeding position. Before welding the second welding cavity and the front plate, the second positioning part pushes the front plate to move towards the first positioning part, so that the front plate is pushed to a position in contact with the first positioning part, achieving the first level positioning. The third positioning part and the fourth positioning part push the other two side walls of the front plate, so that the front plate is arranged in the middle. When the third positioning part and the fourth positioning part contact the front plate at the same time, the second level positioning of the front plate is achieved. The first positioning part, the second positioning part, the third positioning part and the fourth positioning part position the front plate to the welding position, at which the front plate and the second welding cavity are aligned with each other and closely attached, avoiding poor welding and improving the processing precision of the cooking cavity.

[0141] In a possible design, the first positioning part comprises: a first positioning body configured to abut against the front plate, and a second driving member, wherein the first positioning body is arranged on the second driving member, and the second driving member is configured to push the first positioning body to approach or move away from the front plate.

[0142] In this design, the first positioning body serves as a reference part for positioning the front plate. When the front plate needs to be positioned, the second positioning part pushes the front plate towards the first positioning body.

[0143] The second driving member can push the first positioning body to move, so that the first positioning body can approach or move away from the front plate. Specifically, the first positioning body serves as a reference part. When the front plate contacts the first positioning body, the front plate may not be aligned with the second welding cavity. At this time, the second driving member drives the second positioning body to move, so as to adjust the position of the second positioning body, which is conducive to improving the positioning accuracy of the front plate.

[0144] In addition, after the first welding assembly welds the second welding cavity and the front plate, a third welding cavity is obtained, which needs to be transferred to the next station for welding with the rear plate. When the third welding cavity needs to be transferred, the second driving member can drive the first positioning body to move away from the front plate, so as to avoid interference with the transfer process of the third welding cavity.

[0145] For example, the second driving member can be a pneumatic cylinder. The second driving member can also be a combination of a motor and a gear set.

[0146] The second positioning part comprises a first cylinder and a second positioning body, and the first cylinder is used to drive the second positioning body to approach or move away from the front plate.

[0147] The third positioning part comprises a second cylinder and a third positioning body, and the second cylinder is used to drive the third positioning body to approach or move away from the front plate.

[0148] The fourth positioning part comprises a third cylinder and a fourth positioning body, and the third cylinder is used to drive the fourth positioning body to approach or move away from the front plate.

[0149] In a possible design, the first positioning body comprises a third connecting plate, a mounting through hole is arranged on the third connecting plate, at least two abutting parts are arranged on the third connecting plate in a spaced manner, the abutting parts are used to abut against the front plate, the abutting parts are provided with third waist-shaped holes, and a connecting piece passes through the third waist-shaped holes and the mounting through hole to lock the abutting parts on the third connecting plate.

[0150] In this design, the third connecting plate is provided with the mounting through hole, the abutting parts are provided with the third waist-shaped holes, and the connecting piece can pass through the third waist-shaped holes and the mounting through hole to lock the abutting parts on the third connecting plate. Since the connecting piece is provided with the third waist-shaped holes, the connecting piece can slide in the third waist-shaped holes, and the position of the abutting parts on the third connecting plate can be adjusted before the abutting parts are locked on the third connecting plate, so that the abutting parts can be adjusted to a position suitable for positioning the front plate. Through the adjustment of the position of the abutting parts, the positioning of the front plate can be accurately realized.

[0151] The number of the abutting parts can be at least two, and adjacent two of the at least two abutting parts are arranged in a spaced manner. By increasing the number of the abutting parts, the positioning stability of the front plate can be improved, and the situation that the front plate deviates can be avoided.

[0152] The structures of the second positioning body, the third positioning body and the fourth positioning body can be the same as those of the first positioning body, or the second positioning body, the third positioning body and the fourth positioning body can all be provided with a flat plate structure.

[0153] In a possible design, the second positioning assembly further comprises a slide rail arranged on the first rack, the second positioning part is slidably connected to the slide rail, and a third driving member is arranged on the first rack and used to drive the second positioning part to move, so that the second positioning part can avoid the second welding cavity moving towards the first welding position.

[0154] In this design, the second positioning part is arranged on the slide rail, and the third driving member can drive the second positioning part to move, so that the second positioning part can slide relative to the slide rail.

[0155] When the second to-be-welded cavity is moved towards the first welding position by the first transferring assembly, the third driving member drives the second positioning part to move to a position for avoiding the second to-be-welded cavity, so as to avoid interference between the second positioning part and the second to-be-welded cavity. When the second to-be-welded cavity moves to the first welding position, the third driving member pushes the second positioning part, so that the second positioning part moves to a position for pushing the second to-be-welded cavity, thereby ensuring the operation stability of the front plate welding device.

[0156] By arranging the sliding rail on the first rack, the moving stability of the second positioning part is improved.

[0157] In a possible design, the second positioning assembly further includes a fourth driving member arranged on the first rack, and the first positioning part is arranged on the fourth driving member. The fourth driving member is configured to drive the first positioning part to ascend or descend, so that the first positioning part can avoid the second to-be-welded cavity after welding and the front plate.

[0158] In this design, the first positioning part is arranged on the fourth driving member, and the fourth driving member can drive the first positioning part to ascend or descend.

[0159] After the second to-be-welded cavity is welded with the front plate, the third to-be-welded cavity needs to be transferred to the next station. At this time, the fourth driving member drives the first positioning part to descend, so as to avoid interference between the first positioning part and the third to-be-welded cavity, thereby ensuring the operation stability of the front plate welding device. After the third to-be-welded cavity is removed, the fourth driving member drives the first positioning part to ascend, so that the first positioning part can continue to position the next to-be-welded front plate.

[0160] In a possible design, the first transferring assembly includes a support table, and the first positioning assembly is arranged on the support table. The first transferring assembly further includes a first ball screw arranged on the first rack, and the support table is arranged on the first ball screw. The first ball screw is configured to drive the support table to move.

[0161] In this design, the first ball screw can drive the support table to move, so that the support table can drive the first positioning assembly to move.

[0162] The support table serves as a bearing component, and the first positioning assembly can be mounted on the support table. Compared with mounting the first positioning assembly on the first ball screw, mounting the first positioning assembly on the support table can improve the installation convenience of the first positioning assembly. Moreover, the support table can elevate the first positioning assembly above the first ball screw, so as to avoid interference between the second to-be-welded cavity and components on the first ball screw.

[0163] In a possible design, the support table comprises: a first base provided on the first ball screw; a fifth driving member provided on the first base; and a first support seat provided on the first base, wherein the first positioning assembly is provided on the first support seat, the first support seat is slidably connected to the first base, and the fifth driving member is configured to drive the first support seat to ascend or descend.

[0164] In this design, the first base is mounted on the first ball screw, the fifth driving member is mounted on the first base, the first support seat is slidably connected to the first base, and the fifth driving member can drive the first support seat to move, so that the fifth driving member drives the first support seat to ascend or descend.

[0165] The fifth driving member can drive the first support seat to ascend or descend, so that the fifth driving member can indirectly drive the second cavity to ascend or descend. When the support table drives the second cavity to move to the first welding position, the fifth driving member can drive the first support seat to ascend or descend, so as to adjust the height of the second cavity, facilitate the adjustment of the height of the second cavity to be suitable for bearing the front plate, and improve the welding stability of the second cavity and the front plate.

[0166] In a possible design, the second transfer assembly comprises: a second ball screw provided on the first rack; and a second adsorption assembly provided on the second ball screw, wherein the second ball screw is configured to drive the second adsorption assembly to move, and the second adsorption assembly is configured to adsorb the front plate.

[0167] In this design, the second ball screw can drive the second adsorption assembly to move, so that the second adsorption assembly can transfer the second cavity to the first welding position.

[0168] The second adsorption assembly first adsorbs the front plate to be welded, then the second ball screw drives the second adsorption assembly to move above the first welding position, the second adsorption assembly places the front plate to be welded on the second cavity, and then continues to take the next front plate to be welded.

[0169] In a possible design, the second adsorption assembly comprises: a sixth driving member provided on the second ball screw; and a first suction disc provided on the sixth driving member, wherein the sixth driving member is configured to drive the first suction disc to ascend or descend.

[0170] In this design, the sixth driving member is provided on the second ball screw, and the second ball screw can drive the sixth driving member to move. The first suction disc is provided on the sixth driving member, and the sixth driving member can drive the first suction disc to ascend or descend.

[0171] In the material taking process, the sixth driving member can drive the first suction cup to descend, so as to facilitate the first suction cup to suck the front plate. When the sixth driving member moves to the upper side of the first welding position, the sixth driving member can drive the first suction cup to descend, so that the first suction cup can stably place the front plate on the second to-be-welded cavity, thereby improving the stability in the process of transferring the front plate.

[0172] In a possible design, the second transfer assembly further includes a third suction assembly arranged on the second ball screw, and the third suction assembly is configured to suck the welded front plate, so as to drive the welded front plate and the second to-be-welded cavity to move to the unloading position.

[0173] In this design, the third suction assembly is arranged on the second ball screw, and the second ball screw can drive the third suction assembly to move.

[0174] When the welding of the second to-be-welded cavity and the front plate is completed, the third suction assembly can suck the third to-be-welded cavity, and the third suction assembly can drive the third to-be-welded cavity to move to the next work station.

[0175] The second ball screw can simultaneously drive the second suction assembly and the third suction assembly to move, the second suction assembly sucks the front plate, and the third suction assembly sucks the third to-be-welded cavity, so that the material loading process and the material unloading process are synchronized. By using one ball screw to drive two suction assemblies to move, the structure of the front plate welding device is effectively simplified.

[0176] In a possible design, the third suction assembly includes a seventh driving member arranged on the second ball screw, and a second suction cup arranged on the seventh driving member, and the seventh driving member is configured to drive the second suction cup to ascend or descend.

[0177] In this design, the seventh driving member is arranged on the second ball screw, and the second ball screw can drive the seventh driving member to move. The second suction cup is arranged on the seventh driving member, and the seventh driving member can drive the second suction cup to ascend or descend.

[0178] In the material taking process, the seventh driving member can drive the second suction cup to descend, so as to facilitate the second suction cup to stably suck the third to-be-welded cavity.

[0179] In one possible design, the waveguide welding device comprises: a feeding table, the feeding table having an upper feeding position, the feeding table being configured to carry the waveguide and move the waveguide to the upper feeding position; a camera assembly arranged on one side of the feeding table, the camera assembly being configured to detect the position of the waveguide on the upper feeding position; a second picking assembly arranged on one side of the feeding table, the second picking assembly being configured to pick up the waveguide on the upper feeding position according to the detection signal of the camera assembly; an upper feeding assembly arranged on one side of the feeding table, the second picking assembly being configured to place the waveguide on the upper feeding position of the upper feeding assembly, and the upper feeding assembly being configured to move the waveguide to a second welding position; and a second welding assembly arranged on one side of the upper feeding assembly, the second welding assembly being configured to weld the third cavity to be welded and the waveguide.

[0180] In this design, the waveguide placed on the feeding table can be moved to the upper feeding position by the feeding table as a driving component. The upper feeding position refers to the position on the feeding table where the waveguide can be picked up. When the waveguide moves to the upper feeding position, the camera assembly arranged on one side of the feeding table can detect the position of the waveguide on the upper feeding position. According to the detection result of the camera assembly, the second picking assembly can identify the waveguide on the upper feeding position.

[0181] Specifically, when multiple waveguides are transferred to the upper feeding position by the feeding table, the waveguides may be placed in different ways on the upper feeding position, for example, the length direction of some waveguides may be parallel to the conveying direction of the feeding table, and the length direction of some other waveguides may have an angle with the conveying direction of the feeding table, resulting in different placement of the multiple waveguides. The camera assembly can identify the position of the waveguide and determine the position and placement of the waveguide on the upper feeding position. According to the detection result of the camera assembly, the second picking assembly can accurately pick up the waveguide, which is conducive to improving the stability when the waveguide is transferred.

[0182] After the second picking assembly picks up the waveguide, the second picking assembly places the waveguide on the upper feeding position of the upper feeding assembly, and the upper feeding assembly can move the waveguide to the second welding position.

[0183] The second welding assembly is arranged on one side of the upper feeding assembly, and the second welding position is arranged on the second welding assembly. The second welding assembly can weld the third cavity to be welded and the waveguide.

[0184] Since the camera assembly can identify the position of the waveguide, the second picking assembly adjusts the picking angle according to the identification result. Even if the positions and placements of different waveguides are different, the waveguide can be regularly placed on the upper feeding position under the cooperation of the camera assembly and the second picking assembly, realizing the function of positioning and feeding the waveguide. When the upper feeding assembly moves the waveguide to the welding position, the position of the waveguide does not need to be adjusted by the staff, ensuring that the waveguide and the third cavity to be welded can stably complete the welding process.

[0185] The feeding table, the second material taking assembly and the feeding assembly can automatically transfer the waveguide tube, thereby saving the workload of the staff in carrying the waveguide tube.

[0186] The feeding position of the waveguide tube can be adjusted under the cooperation of the camera assembly and the second material taking assembly, so that the staff does not need to adjust the welding position of the waveguide tube, thereby further saving the workload of the staff.

[0187] In a possible design, the feeding assembly comprises a second guide rail assembly, and a fifth positioning assembly provided on the second guide rail assembly, the second guide rail assembly being configured to drive the fifth positioning assembly to reciprocate between the material taking position and the second welding position, and the fifth positioning assembly being configured to carry and position the waveguide tube.

[0188] In this design, the second guide rail assembly can drive the fifth positioning assembly to move, and the waveguide tube can be placed on the fifth positioning assembly, so that the fifth positioning assembly can drive the waveguide tube to move.

[0189] The second material taking assembly can place the waveguide tube on the fifth positioning assembly, and the fifth positioning assembly can position the waveguide tube, so that the waveguide tube is not prone to moving relative to the fifth positioning assembly during the movement of the fifth positioning assembly, and the fifth positioning assembly can drive the waveguide tube to stably move to the second welding position.

[0190] Under the cooperation of the camera assembly and the second material taking assembly, the waveguide tube can be accurately placed on the fifth positioning assembly, and the staff does not need to adjust the position of the waveguide tube under the positioning action of the fifth positioning assembly, so that the third welding assembly can accurately and stably weld the third welding position and the waveguide tube, thereby being favorable for improving the welding precision.

[0191] In a possible design, the fifth positioning assembly comprises a carrying table provided on the second guide rail assembly, a second positioning body provided on the carrying table, a first driving source provided on the carrying table and configured to push the waveguide tube towards the second positioning body, and a second driving source provided on the carrying table and configured to clamp the waveguide tube, and the axial direction of the first driving source and the axial direction of the second driving source are perpendicular to each other.

[0192] In this design, the carrying table is arranged on the second guide rail assembly, and the second guide rail assembly can drive the carrying table to move. The carrying table serves as the carrying structure of the second positioning body, the first driving source and the second driving source, so that the second positioning body, the first driving source and the second driving source can be mounted on the carrying table, and the carrying table can drive the first driving source and the second driving source to move.

[0193] The second positioning body is fixed on the bearing table and is not prone to moving relative to the bearing table. When the waveguide tube is placed between the first driving source and the second positioning body, the first driving source can push the waveguide tube so that the waveguide tube is pushed towards the second positioning body, the first driving source and the second positioning body clamp the waveguide tube, and the first-stage positioning of the waveguide tube is realized. The second driving source can clamp the waveguide tube, the second-stage positioning of the waveguide tube is realized, and the axial direction of the first driving source is perpendicular to the axial direction of the second driving source, so the pushing directions of the first driving source and the second driving source on the waveguide tube are different. For example, the waveguide tube has four first, second, third and fourth side walls connected respectively. The first driving source is used to push the first side wall, the second positioning body is in contact with the third side wall, and the second driving source pushes the second and fourth side walls.

[0194] Since the second driving source can clamp the waveguide tube, the second driving source can push the waveguide tube to be centrally arranged. Under the positioning action of the first driving source and the second driving source, the waveguide tube is pushed to a specified position, it is ensured that the waveguide tube that moves to the second welding position has been subjected to positioning treatment, and it is ensured that the second welding assembly can accurately weld the waveguide tube with the third to-be-welded cavity. In addition, the first driving source and the second positioning body clamp the waveguide tube, and the second driving source clamps the waveguide tube, so that the waveguide tube is not prone to being separated from the bearing table, and it is ensured that the bearing table can stably drive the waveguide tube to move.

[0195] In a possible design, the second driving source includes: a fourth cylinder provided on the bearing table; and third and fourth clamping plates provided on the fourth cylinder, and the fourth cylinder is used to drive the third and fourth clamping plates to move closer to or farther away from each other.

[0196] In this design, the fourth cylinder is installed on the bearing table, the third and fourth clamping plates are installed on the output shaft of the fourth cylinder, and the fourth cylinder can drive the third and fourth clamping plates to move. The third and fourth clamping plates are located on opposite sides of the waveguide tube.

[0197] When the waveguide tube is placed on the bearing table, the fourth cylinder is actuated, the fourth cylinder drives the third and fourth clamping plates to move closer to each other, so that the third and fourth clamping plates push the waveguide tube. When the third and fourth clamping plates clamp the waveguide tube, the third and fourth clamping plates are centrally arranged, and the positioning of the waveguide tube is realized. Moreover, under the clamping action of the third and fourth clamping plates, the waveguide tube is not prone to being separated from the bearing table, and it is ensured that the bearing table can stably drive the waveguide tube to move.

[0198] In a possible design, the second guide rail assembly comprises: a fifth ball screw, the fifth positioning assembly is arranged on the fifth ball screw, and the fifth ball screw is configured to drive the fifth positioning assembly to move in the horizontal direction; and a sixth ball screw, the fifth ball screw is arranged on the sixth ball screw, and the sixth ball screw is configured to drive the fifth ball screw to ascend or descend.

[0199] In this design, the fifth positioning assembly is arranged on the fifth ball screw, and the axial direction of the fifth ball screw extends in the horizontal direction, so that the fifth ball screw can drive the fifth positioning assembly to move in the horizontal direction.

[0200] The fifth ball screw is arranged on the sixth ball screw, and the axial direction of the sixth ball screw extends in the plumb direction, so that the sixth ball screw can drive the fifth ball screw to ascend or descend. The fifth ball screw and the sixth ball screw cooperate to adjust the position of the fifth positioning assembly in the horizontal direction and the plumb direction.

[0201] Specifically, when the fifth positioning assembly needs to take the waveguide pipe, the fifth ball screw drives the fifth positioning assembly to move to the taking position. During the taking process, the sixth ball screw can drive the fifth ball screw to ascend or descend, so as to adjust the height of the fifth positioning assembly to a position suitable for placing the waveguide pipe on the second taking assembly, thereby improving the cooperation stability of the second taking assembly and the second guide rail assembly. When the fifth ball screw drives the fifth positioning assembly to move towards the second welding position, the sixth ball screw can drive the fifth ball screw to ascend or descend, so as to adjust the height of the fifth positioning assembly, so that the height of the fifth positioning assembly is adjusted to a position suitable for placing the waveguide pipe on the second welding assembly for welding, thereby improving the cooperation stability of the second guide rail assembly and the second welding assembly.

[0202] In a possible design, the camera assembly comprises: a frame body; a mounting seat arranged on the mounting seat; and at least one camera arranged on the frame body and located above the feeding table.

[0203] In this design, the mounting seat is arranged on the frame body, and the camera is mounted on the mounting seat. The mounting seat is detachably connected to the frame body, so that the mounting seat and the camera can be disassembled together. When the mounting seat or the camera is damaged, the mounting seat and the camera can be disassembled from the frame body, so that the mounting seat and the camera can be maintained separately, thereby reducing the maintenance cost of the camera assembly.

[0204] The camera is located above the feeding table, so that the camera can obtain the picture on the feeding table. When the waveguide pipe moves to the feeding position, the camera can identify the position of the waveguide pipe and determine the position and placement mode of the waveguide pipe at the feeding position. According to the detection result of the camera, the second taking assembly can accurately pick up the waveguide pipe, thereby improving the stability during the transfer of the waveguide pipe.

[0205] Exemplarily, the camera can be a charge-coupled device camera, which has the advantages of small volume, light weight, no magnetic field interference and anti-vibration, and ensures the stability during the acquisition of the waveguide tube position. The charge-coupled device camera can convert the image into a digital signal, and then the digital signal can be transmitted to the second picking component, so that the second picking component can accurately pick the waveguide tube.

[0206] The number of cameras can be at least one. By increasing the number of cameras, the accuracy of waveguide tube position detection can be improved.

[0207] In a possible design, the camera assembly further includes: a first connecting hole provided on the frame body; at least two second connecting holes provided on the mounting seat; and a locking member penetrating through the first connecting hole and the second connecting hole to lock the mounting seat on the frame body.

[0208] In this design, the frame body is provided with the first connecting hole, the mounting seat is provided with the at least two second connecting holes, and the locking member can penetrate through the first connecting hole and one of the second connecting holes on the mounting seat, so that the locking member can lock the mounting seat on the frame body.

[0209] The locking member can penetrate through any of the second connecting holes on the mounting seat, so that the mounting seat can be connected to different positions of the frame body, and then the relative position of the mounting seat and the frame body can be adjusted. By adjusting the mounting position of the mounting seat, the position of the camera relative to the feeding position can be adjusted, which can facilitate the adjustment of the camera to a position suitable for acquiring the image at the feeding position, and is beneficial to improve the accuracy of image acquisition of the camera.

[0210] Exemplarily, the locking member can be a bolt, and the first connecting hole can be a threaded hole. During installation, the bolt is first penetrated through the second connecting hole, and then the bolt is connected with the threaded hole, so as to lock the mounting seat on the frame body.

[0211] In a possible design, the feeding table includes: a support frame; and a belt assembly provided on the support frame, the belt assembly being used to drive the waveguide tube to move.

[0212] In this design, the belt assembly is installed on the support frame, and the belt assembly can drive the waveguide tube to move, so that the belt assembly can drive the waveguide tube to move to the feeding position. The operation process of the belt assembly is relatively stable, so the belt assembly can stably drive the waveguide tube to move.

[0213] The belt assembly includes: a motor, a driving wheel, a driven wheel and a belt, the belt being sleeved on the driving wheel and the driven wheel, and the motor drives the driving wheel to rotate, so that the driving wheel can drive the belt to rotate.

[0214] In a possible design, the feeding table further includes: a first busbar and a second busbar, which are arranged on the support frame, and are located on two sides of the belt assembly in the width direction, and the distance between at least part of the first busbar and the second busbar decreases in the transmission direction of the belt assembly.

[0215] In this design, the first busbar and the second busbar are arranged on the support frame, and at least part of the first busbar and at least part of the second busbar are located above the belt assembly, and the first busbar and the second busbar are located on two sides of the belt assembly in the transmission direction, so that the first busbar and the second busbar can limit the waveguide pipes conveyed on the belt assembly, avoid the waveguide pipes from falling, and improve the stability of the waveguide pipes when the belt assembly drives the waveguide pipes to move.

[0216] In the transmission direction of the belt assembly, the distance between at least part of the first busbar and the second busbar decreases. The first busbar and the second busbar can play a role of converging, and as the distance between the first busbar and the second busbar decreases, the waveguide pipes are gradually pushed towards the middle of the belt assembly, so that the waveguide pipes are conveyed in the middle of the belt assembly. When the waveguide pipes move to the feeding position, the waveguide pipes are concentrated below the camera, so that the camera can accurately obtain the position of the waveguide pipes.

[0217] For example, in the transmission direction of the belt assembly, the distance between the first busbar and the second busbar first decreases and then remains unchanged. The distance between the first busbar and the second busbar decreases to converge the waveguide pipes, and the distance between the first busbar and the second busbar remains unchanged to avoid the accumulation of multiple waveguide pipes due to the small distance between the first busbar and the second busbar, and to improve the stability of the conveying process.

[0218] In a possible design, the feeding table further includes: a second sensor, which is arranged on the support frame and located at the feeding position, and is configured to detect the position of the waveguide pipe.

[0219] In this design, the second sensor is installed on the support frame, and the second sensor is located at the feeding position, so that the second sensor can detect whether there is a waveguide pipe at the feeding position.

[0220] Specifically, the second sensor can be connected with the belt assembly, and when the second sensor detects that there is a waveguide pipe at the feeding position, the belt assembly stops running, so that the waveguide pipe can stay at the feeding position.

[0221] The second sensor can be linked with the camera assembly. When the second sensor detects that there is a waveguide tube at the feeding position, the camera assembly works and detects the position of the waveguide tube. In this way, the camera assembly can be avoided to be turned on for a long time, which is beneficial to improve the service life of the camera assembly. Moreover, through the detection of the second sensor on whether there is a waveguide tube at the feeding position, the situation of false detection of the camera assembly can be avoided, which is beneficial to improve the operation stability of the waveguide tube welding device.

[0222] Exemplarily, the second sensor can be an infrared sensor or a gravity sensor.

[0223] In a possible design, the feeding table further comprises a baffle provided on the support frame, the baffle being located at one side of the feeding position, and the baffle being used to limit the waveguide tube from separating from the belt assembly.

[0224] In this design, the baffle is arranged on the support frame, and the baffle can block the waveguide tube to avoid the situation of falling of the waveguide tube.

[0225] The baffle can play a protective role. When the second sensor is abnormal, the waveguide tube can move to the feeding position, but the belt assembly does not stop running. The baffle is arranged to block the waveguide tube. Even if the belt assembly does not stop running, the waveguide tube is not easy to fall outside the belt assembly, which reduces the damage rate of the waveguide tube.

[0226] In a possible design, the feeding table further comprises a first height adjusting assembly provided on the support frame, and the first height adjusting assembly is used to adjust the height of the support frame.

[0227] In this design, the first height adjusting assembly can adjust the height of the support frame, so as to indirectly adjust the height of the belt assembly.

[0228] Specifically, by indirectly adjusting the height of the belt assembly through the first height adjusting assembly, the height of the belt assembly can be adjusted to be suitable for the height of the second material taking assembly, so as to improve the cooperation stability of the belt assembly and the second material taking assembly.

[0229] Exemplarily, the bottom of the support frame is provided with a threaded hole, and the first height adjusting assembly comprises a base and a screw rod, the screw rod being connected with the threaded hole. By rotating the screw rod, the length of the screw rod extending into the threaded hole can be adjusted, and then the height of the support frame can be adjusted. Of course, in other designs, the height of the support frame can also be adjusted through mutually sleeved pipes.

[0230] In a possible design, the second material taking assembly comprises a mechanical arm used to pick up the waveguide tube at the feeding position, and a fixing frame, the mechanical arm being arranged on the fixing frame.

[0231] In the design, when the camera assembly acquires the position of the waveguide pipe at the upper loading position, the mechanical arm picks up the waveguide pipe at the upper loading position according to the detection result of the camera assembly. The mechanical arm can be a multi-axis structure, so that the mechanical arm can flexibly adjust the grabbing position, facilitate picking up the waveguide pipe in different positions and different placement modes, and improve the stability of the waveguide pipe transfer process.

[0232] The fixed frame supports the mechanical arm, and the fixed frame can lift the mechanical arm, thereby facilitating the mechanical arm to pick up the waveguide pipe. Compared with the way of increasing the overall height of the mechanical arm, the fixed frame can reduce the processing cost.

[0233] In a possible design, the second material taking assembly further includes a second height adjusting assembly arranged on the fixed frame, and the second height adjusting assembly is configured to adjust the height of the fixed frame.

[0234] In the design, the second height adjusting assembly can adjust the height of the fixed frame, thereby indirectly adjusting the height of the mechanical arm.

[0235] Specifically, by indirectly adjusting the height of the mechanical arm through the second height adjusting assembly, the mechanical arm can be adjusted to a height suitable for picking up the waveguide pipe, thereby improving the cooperation stability of the second height adjusting assembly and the belt assembly.

[0236] For example, the bottom of the fixed frame is provided with a threaded hole, the second height adjusting assembly includes a base and a screw rod, the screw rod is connected with the threaded hole, and by rotating the screw rod, the length of the screw rod extending into the threaded hole can be adjusted, thereby adjusting the height of the fixed frame. Of course, in other designs, the height of the fixed frame can also be adjusted by mutually sleeved pipe bodies.

[0237] In a possible design, the back plate welding device includes: a second rack; a third transfer assembly arranged on the second rack and configured to drive the fourth to-be-welded cavity to move to the third welding position; a fourth transfer assembly arranged on the second rack and configured to drive the back plate to move to the third welding position; a positioning reference portion arranged on the second rack, the fourth to-be-welded cavity abuts against the positioning reference portion when the fourth to-be-welded cavity moves to the third welding position; a third positioning assembly arranged on the third transfer assembly, the third positioning assembly being configured to position the fourth to-be-welded cavity; a fourth positioning assembly arranged on the second rack, the fourth positioning assembly being located at the third welding position, and the fourth positioning assembly being configured to position the back plate; and a third welding assembly arranged on the second rack, the third welding assembly being configured to weld the fourth to-be-welded cavity and the back plate.

[0238] In the design, the third transfer assembly can drive the fourth to-be-welded cavity to move, and the third transfer assembly is provided with a third positioning assembly, which can position the fourth to-be-welded cavity. Under the positioning action of the third positioning assembly, the fourth to-be-welded cavity is not easy to move relative to the third transfer assembly, so that the third positioning assembly can stably drive the fourth to-be-welded cavity to move to the third welding position.

[0239] The fourth to-be-welded cavity can have a three-dimensional structure with four side edges and a front plate, and needs to be welded with the rear plate.

[0240] When the fourth to-be-welded cavity and the rear plate need to be welded, the third transfer assembly drives the fourth to-be-welded cavity to move to the first welding position, and the third positioning assembly can position the fourth to-be-welded cavity during the movement. When the fourth to-be-welded cavity moves to the first welding position, the positioning reference portion abuts against the fourth to-be-welded cavity, and the positioning reference portion limits the continuous movement of the fourth to-be-welded cavity, so as to position the fourth to-be-welded cavity to the third welding position. During the movement, the fourth to-be-welded cavity is not easy to move relative to the third transfer assembly. When the fourth to-be-welded cavity contacts the positioning reference portion, it indicates that the fourth to-be-welded cavity has been accurately moved to the third welding position. Through the cooperation of the third positioning assembly and the positioning reference portion, the stability and accuracy of the welding process are ensured.

[0241] The fourth transfer assembly can drive the rear plate to move to the third welding position, so that the rear plate can be automatically transferred to the third welding position. The third welding assembly near the third welding position can weld the rear plate and the fourth to-be-welded cavity, and automatically complete the welding process.

[0242] The fourth positioning assembly is arranged at the third welding position, which can position the front plate moved to the third welding position, so that the rear plate is accurately positioned to the position to be welded. Moreover, under the positioning action of the fourth positioning assembly, the front plate is not easy to shake, so that the rear plate and the fourth to-be-welded cavity can stably complete the welding process.

[0243] Through the third transfer assembly driving the fourth to-be-welded cavity to move and the fourth transfer assembly driving the rear plate to move, the transfer of the fourth to-be-welded cavity and the rear plate is automatically completed, and the work load of the staff for carrying the fourth to-be-welded cavity and the rear plate is saved.

[0244] The fourth to-be-welded cavity is positioned by the third positioning assembly and the positioning reference part, and the rear plate is positioned by the fourth positioning assembly, so that the positioning of the fourth to-be-welded cavity and the rear plate is automatically realized, the workload of the staff for positioning the fourth to-be-welded cavity and the rear plate is saved, and compared with the manual positioning mode, the positioning mode of the mechanical structure can improve the positioning accuracy, the fourth welding assembly can accurately weld the fourth to-be-welded cavity and the rear plate, and the occurrence of poor welding is avoided, thereby improving the processing accuracy of the cooking cavity.

[0245] In a possible design, the rear plate comprises: a first side edge, a second side edge, a third side edge and a fourth side edge connected in sequence; the fourth positioning assembly comprises: a first positioning member arranged on the second rack and configured to push the first side edge and the second side edge; a second positioning member arranged on the second rack and configured to push the second side edge and the third side edge; a third positioning member arranged on the second rack and configured to push the third side edge and the fourth side edge; and a fourth positioning member arranged on the second rack and configured to push the third side edge and the fourth side edge.

[0246] In this design, the first positioning member is configured to push the first side edge and the second side edge connected in the rear plate, the second positioning member is configured to push the second side edge and the third side edge connected in the rear plate, the third positioning member is configured to push the third side edge and the fourth side edge connected in the rear plate, and the fourth positioning member is configured to push the fourth side edge and the first side edge connected in the rear plate.

[0247] The first positioning member, the second positioning member, the third positioning member and the fourth positioning member push the rear plate, so that the rear plate is centrally arranged at the third welding position, the positioning function of the rear plate is realized, the rear plate is aligned with the fourth to-be-welded cavity, the occurrence of poor welding is avoided, and the processing accuracy of the cooking cavity is improved. The first positioning member, the second positioning member, the third positioning member and the fourth positioning member position the rear plate, so that the staff does not need to adjust the position of the rear plate at the third welding position, thereby saving the workload of the staff.

[0248] The first positioning member, the second positioning member, the third positioning member and the fourth positioning member can clamp the rear plate, so that the rear plate is not prone to shaking during welding, and the stability during welding is improved.

[0249] In a possible design, the first positioning member comprises: a first driving part arranged on the second rack; and a first pushing plate and a second pushing plate, the first pushing plate is connected to the second pushing plate, and the first pushing plate and / or the second pushing plate is arranged on the first driving part, the first pushing plate is configured to push the first side edge, and the second pushing plate is configured to push the second side edge.

[0250] In this design, the first pushing plate and the second pushing plate are connected, and the first positioning member can drive the first pushing plate and the second pushing plate to move.

[0251] The second positioning member comprises: a second driving portion arranged on the second rack; a third pushing plate and a fourth pushing plate, the third pushing plate is connected to the fourth pushing plate, and the third pushing plate and / or the fourth pushing plate are arranged on the second driving portion, the third pushing plate is used for pushing the second side edge, and the fourth pushing plate is used for pushing the third side edge.

[0252] The third positioning member comprises: a third driving portion arranged on the second rack; a fifth pushing plate and a sixth pushing plate, the fifth pushing plate is connected to the sixth pushing plate, and the fifth pushing plate and / or the sixth pushing plate are arranged on the third driving portion, the fifth pushing plate is used for pushing the third side edge, and the sixth pushing plate is used for pushing the fourth side edge.

[0253] The fourth positioning member comprises: a fourth driving portion arranged on the second rack; a seventh pushing plate and an eighth pushing plate, the seventh pushing plate is connected to the eighth pushing plate, and the seventh pushing plate and / or the eighth pushing plate are arranged on the fourth driving portion, the seventh pushing plate is used for pushing the fourth side edge, and the eighth pushing plate is used for pushing the first side edge.

[0254] During the positioning process of the rear plate, the four positioning members can act simultaneously, for example, the first driving portion drives the first pushing plate and the second pushing plate to move, the first pushing plate contacts the first side edge, the third driving portion drives the fifth pushing plate and the sixth pushing plate to move, the fifth pushing plate contacts and pushes the third side edge, and after the pushing of the fifth pushing plate, the second side edge contacts the second pushing plate, so that the positioning of the second side edge is realized, and the other side edges are the same.

[0255] In a possible application, the included angle between the first pushing plate and the second pushing plate is 90°.

[0256] In a possible design, the positioning reference portion comprises: a fifth driving portion; and a first positioning plate arranged on the fifth driving portion, and the fifth driving portion is used for driving the first positioning plate to move towards or away from the fourth welding cavity.

[0257] In this design, the first positioning plate serves as the reference portion for positioning the fourth welding cavity, and when the third transfer assembly drives the fourth welding cavity to move to contact the first positioning plate, it indicates that the fourth welding cavity is moved to the position.

[0258] The fifth driving portion can drive the first positioning plate to move, so that the first positioning plate can approach or move away from the fourth welding cavity. Specifically, the first positioning plate serves as the reference portion, and when the fourth welding cavity contacts the first positioning plate, the rear plate and the fourth welding cavity can not be aligned. At this time, the fifth driving portion is needed to drive the second positioning plate to move, so as to adjust the position of the second positioning plate, which is beneficial to improve the positioning accuracy of the fourth welding cavity.

[0259] In addition, after the fourth to-be-welded cavity and the rear plate are welded, a fifth to-be-welded cavity is obtained, and the fifth to-be-welded cavity needs to be transferred to the next station for processing. When the fifth to-be-welded cavity needs to be transferred, the fifth driving part can drive the first positioning plate to move away from the fifth to-be-welded cavity, so as to avoid interference with the transfer process of the fifth to-be-welded cavity.

[0260] In a possible design, the positioning reference part further includes: a sixth driving part; and a second positioning plate provided on the sixth driving part, the second positioning plate being in contact with the side wall of the rear plate when the rear plate is located at the third welding position, and the sixth driving part being configured to drive the second positioning plate to move towards or away from the rear plate.

[0261] In this design, when the rear plate is placed above the fourth to-be-welded cavity, the rear plate may deviate from the welding position by a large distance, and at this time, the fourth positioning assembly may not be able to adjust the position of the rear plate. The sixth driving part can push the second positioning plate, so that the second positioning plate pushes the rear plate. The second positioning plate can push the rear plate to a range that can be adjusted by the fourth positioning assembly, which is beneficial to improve the stability during welding.

[0262] After welding is completed, the sixth driving part drives the second positioning plate to move away from the rear plate, so as to avoid interference with the transfer process of the fifth to-be-welded cavity.

[0263] In a possible design, the positioning reference part further includes: a seventh driving part provided on the second rack, and the fifth driving part and the sixth driving part are provided on the seventh driving part, and the seventh driving part is configured to drive the fifth driving part and the sixth driving part to ascend or descend, so that the positioning reference part can avoid the fourth to-be-welded cavity and the rear plate after welding.

[0264] In this design, the fifth driving part and the sixth driving part are arranged on the seventh driving part, and the seventh driving part can drive the fifth driving part and the sixth driving part to ascend or descend.

[0265] When the fourth to-be-welded cavity and the rear plate are welded, the fifth to-be-welded cavity needs to be transferred to the next station, and at this time, the seventh driving part can drive the fifth driving part and the sixth driving part to descend, so as to avoid interference between the fifth driving part and the sixth driving part and the fifth to-be-welded cavity, and ensure the operation stability of the rear plate welding device. When the fifth to-be-welded cavity is removed, the seventh driving part drives the fifth driving part and the sixth driving part to ascend, so that the fifth driving part and the sixth driving part can continue to position the next to-be-welded rear plate and the fourth to-be-welded cavity.

[0266] In a possible design, the third positioning assembly includes: a second support rib; and an eighth driving part provided on the third transfer assembly, and the eighth driving part is configured to drive the second support rib to move, so that the second support rib abuts against the plurality of inner walls of the fourth to-be-welded cavity.

[0267] In this design, when the fourth to-be-welded cavity is placed on the third transfer assembly, the eighth driving part drives the second supporting rib to move, so that the second supporting rib can be in contact with the plurality of inner walls in the fourth to-be-welded cavity.

[0268] The fourth to-be-welded cavity has four side walls, and the eighth driving part can drive the second supporting rib to be in contact with the four side walls in the fourth to-be-welded cavity. The second supporting rib supports the inner walls of the fourth to-be-welded cavity, thereby fixing the fourth to-be-welded cavity on the third transfer assembly.

[0269] Since the second supporting rib can be in contact with the plurality of side walls in the fourth to-be-welded cavity, the second supporting rib can push the plurality of side walls in the fourth to-be-welded cavity, thereby adjusting the position of the fourth to-be-welded cavity on the third transfer assembly, achieving the function of positioning the fourth to-be-welded cavity. When the third transfer assembly moves the fourth to-be-welded cavity to the third welding position, the position of the fourth to-be-welded cavity does not need to be adjusted, which is conducive to realizing precise welding of the fourth to-be-welded cavity and the front plate.

[0270] The second supporting rib supports the fourth to-be-welded cavity, so that the fourth to-be-welded cavity is not easy to shake relative to the third transfer assembly, which is conducive to improving the stability when transferring the fourth to-be-welded cavity.

[0271] In a possible design, the fourth to-be-welded cavity includes a first inner wall, a second inner wall, a third inner wall, and a fourth inner wall. The eighth driving part includes a first sub-driving member and a second sub-driving member. The second supporting rib includes a fifth supporting part and a sixth supporting part connected to each other, which are arranged on the first sub-driving member, and the fifth supporting part and the sixth supporting part are respectively used for abutting against the first inner wall and the second inner wall. A seventh supporting part and an eighth supporting part connected to each other are arranged on the second sub-driving member, and the seventh supporting part and the eighth supporting part are respectively used for abutting against the third inner wall and the fourth inner wall.

[0272] In this design, the second supporting rib includes a fifth supporting part, a sixth supporting part, a seventh supporting part, and an eighth supporting part, which are respectively used for contacting the first inner wall, the second inner wall, the third inner wall, and the fourth inner wall in the fourth to-be-welded cavity. The fifth supporting part and the sixth supporting part are connected to each other, and the fifth supporting part and / or the sixth supporting part are arranged on the first sub-driving member, so that the first sub-driving member can drive the fifth supporting part and the sixth supporting part to move. The seventh supporting part and the eighth supporting part are connected to each other, and the seventh supporting part and / or the eighth supporting part are arranged on the second sub-driving member, so that the second sub-driving member can drive the seventh supporting part and the eighth supporting part to move.

[0273] The first sub-driving member and the second sub-driving member can be arranged to be perpendicular to each other in the axial direction. For example, the first sub-driving member drives the fifth support portion to push the first inner wall, and as the first inner wall is pushed, the third inner wall is in contact with the seventh support portion. The second sub-driving member drives the eighth support portion to push the fourth inner wall, and as the fourth inner wall is pushed, the second inner wall is in contact with the first support plate. In this way, the fourth to-be-welded cavity is positioned.

[0274] Of course, in other designs, the fifth support portion, the sixth support portion, the seventh support portion, and the eighth support portion can be driven to move by four sub-driving members respectively.

[0275] In a possible design, the third transferring assembly includes a fixed table, and the third positioning assembly is arranged on the fixed table; and a third ball screw is arranged on the second rack, and the fixed table is arranged on the third ball screw, and the third ball screw is configured to drive the fixed table to move.

[0276] In this design, the third ball screw can drive the fixed table to move, so that the fixed table can drive the third positioning assembly to move.

[0277] The fixed table serves as a bearing component, and the third positioning assembly can be mounted on the fixed table. Compared with supporting and mounting the third positioning assembly on the third ball screw, mounting the third positioning assembly on the fixed table can improve the mounting convenience of the third positioning assembly. Moreover, the fixed table can elevate the third positioning assembly above the first ball screw, so that the fourth to-be-welded cavity does not interfere with the components on the third ball screw.

[0278] In a possible design, the fixed table includes a second base arranged on the third ball screw, a ninth driving portion arranged on the second base, and a second support seat arranged on the second base, and the third positioning assembly is arranged on the second support seat, and the second support seat is slidingly connected to the second base, and the ninth driving portion is configured to drive the second support seat to ascend or descend.

[0279] In this design, the second base is mounted on the third ball screw, the ninth driving portion is mounted on the second base, the second support seat is slidingly connected to the second base, and the ninth driving portion can drive the second support seat to move, so that the ninth driving portion drives the second support seat to ascend or descend.

[0280] The ninth driving portion can drive the second support seat to ascend or descend, so that the ninth driving portion can indirectly drive the fourth to-be-welded cavity to ascend or descend. When the fixed table drives the fourth to-be-welded cavity to move to the third welding position, the ninth driving portion can drive the second support seat to ascend or descend, so as to adjust the height of the fourth to-be-welded cavity, facilitate adjustment of the fourth to-be-welded cavity to a height suitable for bearing the rear plate, and improve the welding stability of the fourth to-be-welded cavity and the rear plate.

[0281] In a possible design, the fourth transfer assembly comprises: a fourth ball screw arranged on the second rack; and a fourth adsorption assembly arranged on the fourth ball screw, wherein the fourth ball screw is configured to drive the fourth adsorption assembly to move, and the fourth adsorption assembly is configured to adsorb the back plate.

[0282] In this design, the fourth ball screw can drive the fourth adsorption assembly to move, so that the fourth adsorption assembly can transfer the fourth to-be-welded cavity to the third welding position.

[0283] The fourth adsorption assembly first adsorbs the to-be-welded back plate, and then the fourth ball screw drives the fourth adsorption assembly to move to above the third welding position. The fourth adsorption assembly places the to-be-welded back plate on the fourth to-be-welded cavity, and then continues to take the next to-be-welded back plate.

[0284] In a possible design, the fourth adsorption assembly comprises: a tenth driving part arranged on the fourth ball screw; and a third suction disc arranged on the tenth driving part, wherein the tenth driving part is configured to drive the third suction disc to ascend or descend.

[0285] In this design, the tenth driving part is arranged on the fourth ball screw, and the fourth ball screw can drive the tenth driving part to move. The third suction disc is arranged on the tenth driving part, and the tenth driving part can drive the third suction disc to ascend or descend.

[0286] During the taking process, the tenth driving part can drive the third suction disc to descend, so as to facilitate the third suction disc to adsorb the back plate. When the tenth driving part moves to above the third welding position, the tenth driving part can drive the third suction disc to descend, so that the third suction disc can stably place the front plate on the fourth to-be-welded cavity, thereby improving the stability during the transferring process of the back plate.

[0287] In a possible design, the fourth transfer assembly further comprises: a fifth adsorption assembly arranged on the fourth ball screw, wherein the fourth ball screw is configured to drive the fifth adsorption assembly to move, and the fifth adsorption assembly is configured to adsorb the welded back plate, so as to drive the welded back plate and the fourth to-be-welded cavity to move to the downward position.

[0288] In this design, the fifth adsorption assembly is arranged on the fourth ball screw, and the fourth ball screw can drive the fifth adsorption assembly to move.

[0289] When the fourth to-be-welded cavity and the back plate are welded, the fifth adsorption assembly can adsorb the fourth to-be-welded cavity, and the fifth adsorption assembly can drive the fourth to-be-welded cavity to move to the next station.

[0290] The fourth ball screw can drive the fourth adsorption assembly and the fifth adsorption assembly to move simultaneously, the fourth adsorption assembly adsorbs the back plate, and the fifth adsorption assembly adsorbs the fourth cavity to be welded, so that the feeding process and the discharging process are synchronized.

[0291] In a possible design, the fifth adsorption assembly comprises an eleventh driving part arranged on the fourth ball screw, and a fourth suction disc arranged on the eleventh driving part, and the eleventh driving part is configured to drive the fourth suction disc to ascend or descend.

[0292] In this design, the eleventh driving part is arranged on the fourth ball screw, and the fourth ball screw can drive the eleventh driving part to move. The fourth suction disc is arranged on the eleventh driving part, and the eleventh driving part can drive the fourth suction disc to ascend or descend.

[0293] In the material taking process, the eleventh driving part can drive the fourth suction disc to descend, so that the fourth suction disc can stably adsorb the fourth cavity to be welded.

[0294] In a possible design, the back plate welding device further comprises a base arranged on the second rack and located at the third welding position, and the base is configured to support the flange of the fourth cavity to be welded.

[0295] In this design, when the third transfer assembly drives the fourth cavity to be welded to move to the third welding position, the base is located below the flange of the fourth cavity to be welded, and at this time, the ninth driving part drives the second support base to descend, so that the fourth cavity to be welded is placed on the base, and the fourth cavity to be welded is separated from the third transfer assembly. The third transfer assembly can return to carry the next fourth cavity to be welded, which is beneficial to improve the welding efficiency.

[0296] Since the fourth cavity to be welded has been welded with the front plate, the fourth cavity to be welded is not easy to deform, so the second supporting rib is not needed to support and correct the shape of the fourth cavity to be welded.

[0329] In order to enable anyone skilled in the art to better understand the above-mentioned objects, features and advantages of the present application, further specific description of the present application will be given below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0330] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0331] The following description refers to the accompanying drawings and specific embodiments. Figures 1 to 20 The following description refers to the accompanying drawings and specific embodiments.

[0332] In combination with Figure 1 , Figure 2 , Figure 5 , Figure 11 , Figure 13 , Figure 16 , and Figure 18As shown, in some embodiments of the present application, a material production system is provided, comprising: a feeding device 100, a top plate welding device 200, a material transfer device 300, a front plate welding device 400, a waveguide welding device 500, a feeding device 600, and a rear plate welding device 700. The feeding device 100 is used to correct the first to-be-welded cavity 810. The top plate welding device 200 is arranged on one side of the feeding device 100. The feeding device 100 is used to place the first to-be-welded cavity 810 on the top plate welding device 200. The top plate welding device 200 is used to weld the first to-be-welded cavity 810 and the top plate to obtain the second to-be-welded cavity 820. The material transfer device 300 is arranged on one side of the feeding device 100 and is used to transfer the second to-be-welded cavity 820. The front plate welding device 400 is arranged on one side of the feeding device 100. The material transfer device 300 is used to place the second to-be-welded cavity 820 on the front plate welding device 400. The front plate welding device 400 is used to weld the second to-be-welded cavity 820 and the front plate 910 to obtain the third to-be-welded cavity 830. The feeding device 600 is arranged on one side of the front plate welding device 400. The waveguide welding device 500 is arranged on one side of the front plate welding device 400. The feeding device 600 is used to place the third to-be-welded cavity 830 on the waveguide welding device 500. The waveguide welding device 500 is used to weld the third to-be-welded cavity 830 and the waveguide 920 to obtain the fourth to-be-welded cavity 840. The rear plate welding device 700 is arranged on one side of the feeding device 600. The feeding device 600 is used to place the fourth to-be-welded cavity 840 on the rear plate welding device 700. The rear plate welding device 700 is used to weld the fourth to-be-welded cavity 840 and the rear plate 930.

[0333] The material production system provided by the present application needs to use a bending machine to bend the plate into a U-shaped plate to obtain the first to-be-welded cavity 810 during the processing of the cooking cavity. Then the U-shaped plate is welded with the top plate to form a three-dimensional structure with four sides. Then the three-dimensional structure is welded with the front plate 910, the waveguide 920, and the rear plate 930. Due to the deformation of the plate, the angle between the two adjacent sides of the U-shaped plate may not be a right angle. When the U-shaped plate is welded with the top plate, the U-shaped plate and the front plate 910 are difficult to closely contact. The feeding device 100 can correct the first to-be-welded cavity 810 during the feeding process, so as to ensure that the first to-be-welded cavity 810 is corrected to a standard to-be-welded cavity structure. It is ensured that the first to-be-welded cavity 810 placed in the to-be-welded position does not deform, so that the first to-be-welded cavity 810 can closely contact with the top plate, avoiding the occurrence of poor welding, and being conducive to improving the processing precision of the cooking cavity.

[0334] The top plate welding device 200 is used for welding the first to-be-welded cavity 810 and the top plate to obtain the second to-be-welded cavity 820. The feeding device 100 can place the first to-be-welded cavity 810 at a welding position of the top plate welding device 200. The mechanical arm assembly can transfer the top plate to the welding position. The top plate welding device 200 includes a pneumatic cylinder and a welding machine. The pneumatic cylinder can drive the welding machine to move. When the welding machine moves to the connection position of the top plate and the first to-be-welded cavity 810, the welding machine welds the connection position of the top plate and the first to-be-welded cavity 810.

[0335] The material transfer device 300 can pick up the second to-be-welded cavity 820 at the welding position of the top plate welding device 200, and then place the second to-be-welded cavity 820 at the front plate welding device 400. The front plate welding device 400 can weld the front plate 910 and the second to-be-welded cavity 820 to obtain the third to-be-welded cavity 830.

[0336] The front plate welding device 400 can place the third to-be-welded cavity 830 at the waveguide tube welding device 500. The waveguide tube welding device 500 is used for welding the waveguide tube and the third to-be-welded cavity 830 to obtain the fourth to-be-welded cavity 840.

[0337] The waveguide tube welding device 500 can place the fourth to-be-welded cavity 840 at the rear plate welding device 700. The rear plate welding device 700 can weld the rear plate 930 and the fourth to-be-welded cavity 840 to obtain the cooking cavity. The feeding device 600 is used for placing the third to-be-welded cavity at the welding position of the waveguide tube welding device 500.

[0338] After the waveguide tube welding device 500 welds the waveguide tube 920 and the third to-be-welded cavity 830 to obtain the fourth to-be-welded cavity 840, the feeding device 600 can transfer the fourth to-be-welded cavity 840 to the rear plate welding device 700. The rear plate welding device 700 can weld the rear plate 930 and the fourth to-be-welded cavity 840 to obtain the cooking cavity.

[0339] Through the above device, the transfer and welding of the material are automatically realized, and the staff does not need to carry and weld the plate, thereby reducing the workload of the staff. Moreover, the automatic production mode can effectively improve the processing efficiency of the cooking cavity.

[0340] Exemplarily, the feeding device 600 can be a mechanical arm assembly.

[0341] In combination Figure 2 and Figure 4As shown, the feeding device 100 comprises: a feeding table 110, a first correcting assembly 120, a second correcting assembly 130 and a first material taking assembly 140; the first correcting assembly 120 and the second correcting assembly 130 are arranged on the feeding table 110, the first correcting assembly 120 is used for clamping a first side edge in the first to-be-welded cavity 810, and the second correcting assembly 130 is used for clamping a second side edge in the first to-be-welded cavity 810; a part of the first material taking assembly 140 can extend into the first to-be-welded cavity 810, and the part of the first material taking assembly 140 extending into the first to-be-welded cavity 810 adsorbs the first side edge and the second side edge, so that the first material taking assembly 140 can drive the first to-be-welded cavity 810 to move.

[0342] The feeding device 100 provided by the embodiment, the first correcting assembly 120 and the second correcting assembly 130 are fixed on the feeding table 110, the first correcting assembly 120 is located at a first correcting position, the second correcting assembly 130 is located at a second correcting position, and the first correcting assembly 120 and the second correcting assembly 130 are used for correcting the interval between the first side edge and the second side edge in the first to-be-welded cavity 810.

[0343] During the processing of the cooking cavity, the plate material needs to be bent to form a U-shaped plate, i.e., the first to-be-welded cavity 810, and then the U-shaped plate is welded with the side plate to form a three-dimensional structure with four side edges, and then the three-dimensional structure with the welded side plate is welded with the top plate and the back plate 930.

[0344] Due to the influence of plate deformation, the angle between the two adjacent side edges in the U-shaped plate may not be a right angle, and the U-shaped plate and the front plate 910 are difficult to closely contact when the U-shaped plate is welded with the top plate. In the present application, the first correcting assembly 120 and the second correcting assembly 130 correct the shape of the first to-be-welded cavity 810, so that the first to-be-welded cavity 810 is corrected to a standard to-be-welded cavity structure, so as to facilitate subsequent stable welding.

[0345] Specifically, the first to-be-welded cavity 810 has three side edges, i.e., a first side edge, a second side edge and a third side edge, the interval between the clamping position on the first correcting assembly 120 and the clamping position on the second correcting assembly 130 is equal to the length of the third side edge, when the first side edge and the second side edge are clamped by the first correcting assembly 120 and the second correcting assembly 130 respectively, the angle between the two adjacent side edges is 90°, so as to ensure that the first to-be-welded cavity 810 is corrected to a standard to-be-welded cavity structure.

[0346] After the first correcting assembly 120 and the second correcting assembly 130 correct the shape of the first to-be-welded cavity 810, the first material taking assembly 140 needs to transfer the first to-be-welded cavity 810, so as to transfer the first to-be-welded cavity 810 to a to-be-welded position.

[0347] Specifically, when the first to-be-welded cavity 810 needs to be transferred, at least part of the first material taking assembly 140 extends into the first to-be-welded cavity 810, and the part of the first material taking assembly 140 extending into the first to-be-welded cavity 810 adsorbs the first side edge and the second side edge. Since the distance between the first side edge and the second side edge has been adjusted, when the first material taking assembly 140 adsorbs the first side edge and the second side edge, it is ensured that the distance between the first side edge and the second side edge is equal to the length of the third side edge. During the process of transferring the first to-be-welded cavity 810 by the first material taking assembly 140, the first material taking assembly 140 can play a positioning function on the first side edge and the second side edge. Under the support of the first material taking assembly 140, the distance between the first side edge and the second side edge is not easy to decrease, and under the adsorption of the first material taking assembly 140, the distance between the first side edge and the second side edge is not easy to increase. During the transfer process, the first to-be-welded cavity always maintains the standard to-be-welded cavity structure. It is ensured that the first to-be-welded cavity 810 placed in the to-be-welded position does not deform, so that the first to-be-welded cavity 810 can be closely attached to the side plate, avoiding the occurrence of poor welding, and being beneficial to improving the machining precision of the cooking cavity.

[0348] By transferring the first to-be-welded cavity 810 by the first material taking assembly 140, automatic handling of the first to-be-welded cavity 810 is realized, saving the work amount of the staff for handling the first to-be-welded cavity 810.

[0349] By correcting the shape of the first to-be-welded cavity 810 by the first correcting assembly 120 and the second correcting assembly 130, it is ensured that the first to-be-welded cavity 810 is a standard structure without deformation, and the staff does not need to pull the deformed first to-be-welded cavity 810, further saving the work amount of the staff.

[0350] In combination Figure 2 and Figure 3 As shown in FIGS. 1, 2 and 3, in a possible embodiment, the first correcting assembly 120 comprises a first power part 121, a first clamping plate 122 and a second clamping plate 123. The first power part 121 is arranged on the feeding table 110. The first clamping plate 122 and the second clamping plate 123 are arranged on the first power part 121. The first power part 121 is used to drive the first clamping plate 122 and the second clamping plate 123 to approach or move away from each other.

[0351] In this embodiment, the first power part 121 can drive the first clamping plate 122 and the second clamping plate 123 to move, so that the first clamping plate 122 and the second clamping plate 123 approach or move away from each other.

[0352] Before loading, the first power part 121 drives the first clamping plate 122 and the second clamping plate 123 to move away from each other, and the first clamping plate 122 and the second clamping plate 123 have a gap therebetween, and the first side edge in the first to-be-welded cavity 810 extends into the gap between the first clamping plate 122 and the second clamping plate 123. The first power part 121 drives the first clamping plate 122 and the second clamping plate 123 to move close to each other, and if the first side edge is deformed, the shape of the first side edge can be corrected by the first clamping plate 122 and the second clamping plate 123.

[0353] In this embodiment, the first power part 121 can be a pneumatic clamp jaw, and in other embodiments, a pneumatic cylinder can be provided as the first power part 121, and the first clamping plate 122 is driven to move by the pneumatic cylinder to move close to or away from the second clamping plate 123.

[0354] In combination with FIGS. 1 and 2, Figure 2 and Figure 3 As shown in FIGS. 1 and 2, the second correction assembly 130 includes a second power part 131, a third clamping plate 132, and a fourth clamping plate 133. The second power part 131 is arranged on the loading table 110. The third clamping plate 132 and the fourth clamping plate 133 are arranged on the second power part 131, and the second power part 131 is configured to drive the third clamping plate 132 and the fourth clamping plate 133 to move close to or away from each other.

[0355] The second power part 131 can drive the third clamping plate 132 and the fourth clamping plate 133 to move, so that the third clamping plate 132 and the fourth clamping plate 133 move close to or away from each other.

[0356] Before loading, the second power part 131 drives the third clamping plate 132 and the fourth clamping plate 133 to move away from each other, and the third clamping plate 132 and the fourth clamping plate 133 have a gap therebetween, and the second side edge in the first to-be-welded cavity 810 extends into the gap between the third clamping plate 132 and the fourth clamping plate 133. The second power part 131 drives the third clamping plate 132 and the fourth clamping plate 133 to move close to each other, and if the second side edge is deformed, the shape of the second side edge can be corrected by the third clamping plate 132 and the fourth clamping plate 133.

[0357] In this embodiment, the second power part 131 can be a pneumatic clamp jaw, and in other embodiments, a pneumatic cylinder can be provided as the second power part 131, and the third clamping plate 132 is driven to move by the pneumatic cylinder to move close to or away from the fourth clamping plate 133.

[0358] In combination with FIGS. 1 and 2, Figure 2 and Figure 3As shown, in one possible embodiment, the first correcting assembly 120 further comprises: at least one first guiding assembly 150, the at least one first guiding assembly 150 is arranged on the first clamping plate 122 and / or the second clamping plate 123, and the first guiding assembly 150 is used to guide the first side edge to extend into the first clamping plate 122 and the second clamping plate 123.

[0359] In this embodiment, the first guiding assembly 150 is arranged on the first clamping plate 122 and / or the second clamping plate 123, and the first guiding assembly 150 can guide the first side edge which needs to extend into the first clamping plate 122 and the second clamping plate 123.

[0360] The maximum distance between the first clamping plate 122 and the second clamping plate 123 is limited, and during the process of placing the first to-be-welded cavity 810 on the upper table 110, the first side edge may not be able to extend into the first clamping plate 122 and the second clamping plate 123 due to the large deformation of the adjacent two side edges in the first to-be-welded cavity 810. By adding the first guiding assembly 150, the first guiding assembly 150 guides the first side edge, which facilitates the first side edge to extend into the first clamping plate 122 and the second clamping plate 123 under the guidance of the first guiding assembly 150. By adding the first guiding assembly 150, the staff does not need to manually move the first side edge, which facilitates the first side edge to automatically extend into the first clamping plate 122 and the second clamping plate 123.

[0361] The second correcting assembly 130 further comprises: at least one second guiding assembly 160, the at least one second guiding assembly 160 is arranged on the third clamping plate 132 and / or the fourth clamping plate 133, and the second guiding assembly 160 is used to guide the second side edge to extend into the third clamping plate 132 and the fourth clamping plate 133.

[0362] The second guiding assembly 160 is arranged on the third clamping plate 132 and / or the fourth clamping plate 133, and the second guiding assembly 160 can guide the second side edge which needs to extend into the third clamping plate 132 and the fourth clamping plate 133.

[0363] The maximum distance that the third clamping plate 132 and the fourth clamping plate 133 can maintain from each other is limited. During the process of placing the first cavity to be welded 810 onto the upper loading table 110, a situation may occur where the deformation of two adjacent sides of the first cavity to be welded 810 is too large, preventing the second side from extending between the third clamping plate 132 and the fourth clamping plate 133. By adding a second guide component 160, the second guide component 160 guides the second side, facilitating its extension between the third clamping plate 132 and the fourth clamping plate 133. By adding the second guide component 160, manual movement of the second side is eliminated, allowing it to automatically extend between the third clamping plate 132 and the fourth clamping plate 133.

[0364] Combination Figure 2 and Figure 3 As shown, in one possible embodiment, the first guide assembly 150 includes: a first guide plate 151 and a second guide plate 152, the first guide plate 151 being disposed on the first clamping plate 122; the second guide plate 152 being disposed on the second clamping plate 123, and the distance between the first guide plate 151 and the second guide plate 152 increasing in the direction away from the first clamping plate 122 and the second clamping plate 123.

[0365] In this embodiment, a first guide plate 151 is disposed on a first clamping plate 122, and a second guide plate 152 is disposed on a second clamping plate 123. From bottom to top, the distance between the first guide plate 151 and the second guide plate 152 gradually increases, forming a flared structure between them. Because the distance between the first guide plate 151 and the second guide plate 152 is larger at the top, it facilitates the first side extending between them. Along the direction of the first side extending, the distance between the first guide plate 151 and the second guide plate 152 gradually decreases. Under the guiding action of the first guide plate 151 and the second guide plate 152, the first side is gradually guided between the first clamping plate 122 and the second clamping plate 123, allowing the first clamping plate 122 and the second clamping plate 123 to correct the shape of the first side, which helps improve the stability of the feeding process.

[0366] The second guide assembly 160 includes a third guide plate 161 and a fourth guide plate 162. The third guide plate 161 is disposed on the third clamping plate 132. The fourth guide plate 162 is disposed on the fourth clamping plate 133. The distance between the third guide plate 161 and the fourth guide plate 162 increases in the direction away from the third clamping plate 132 and the fourth clamping plate 133.

[0367] A third guide plate 161 is disposed on a third clamping plate 132, and a fourth guide plate 162 is disposed on a fourth clamping plate 133. From bottom to top, the distance between the third guide plate 161 and the fourth guide plate 162 gradually increases, forming a flared structure between them. Because the distance between the third guide plate 161 and the fourth guide plate 162 is larger at the top, it facilitates the second side extending between them. Along the direction of the second side's extension, the distance between the third guide plate 161 and the fourth guide plate 162 gradually decreases. Under the guidance of the third guide plate 161 and the fourth guide plate 162, the second side is gradually guided between the third clamping plate 132 and the fourth clamping plate 133, allowing the third clamping plate 132 and the fourth clamping plate 133 to correct the shape of the second side, thus improving the stability of the feeding process.

[0368] Combination Figure 2 and Figure 3 As shown, in one possible embodiment, the first guide assembly 150 further includes: a first mounting hole, a second oblong hole, a first locking member, a second mounting hole, a fifth oblong hole, and a second locking member. The first mounting hole is disposed in the first clamping plate 122; the fourth oblong hole is disposed in the first guide plate 151; the first locking member passes through the first mounting hole and the fourth oblong hole to lock the first guide plate 151 to the first clamping plate 122. The second mounting hole is disposed in the second clamping plate 123; the fifth oblong hole is disposed in the second guide plate 152; the second locking member passes through the second mounting hole and the fifth oblong hole to lock the second guide plate 152 to the second clamping plate 123.

[0369] In this embodiment, the first locking member can pass through the fourth oblong hole and the first mounting hole, thereby locking the first guide plate 151 to the first clamping plate 122. Since the first guide plate 151 is provided with an oblong hole, the position of the first guide plate 151 on the first clamping plate 122 can be adjusted before the first locking member is locked to the first guide plate 151, thereby facilitating the adjustment of the first guide plate 151 to a position suitable for guiding the first side.

[0370] Similarly, the second locking member can pass through the fifth oblong hole and the second mounting hole to lock the second guide plate 152 onto the second clamping plate 123. Because the second guide plate 152 has an oblong hole, the position of the second guide plate 152 on the second clamping plate 123 can be adjusted before locking the second locking member onto the second guide plate 152, thereby facilitating the adjustment of the second guide plate 152 to a position suitable for guiding the first side.

[0371] For example, the first locking member and the second locking member are bolts, and the first mounting hole and the second mounting hole are threaded holes.

[0372] The second guiding assembly 160 further comprises a third mounting hole, a sixth waist-shaped hole, a third locking member, a fourth mounting hole, a seventh waist-shaped hole and a fourth locking member. The third mounting hole is arranged on the third clamping plate 132. The sixth waist-shaped hole is arranged on the third guiding plate 161. The third locking member passes through the third mounting hole and the sixth waist-shaped hole to lock the third guiding plate 161 on the third clamping plate 132. The fourth mounting hole is arranged on the fourth clamping plate 133. The seventh waist-shaped hole is arranged on the fourth guiding plate 162. The fourth locking member passes through the fourth mounting hole and the seventh waist-shaped hole to lock the fourth guiding plate 162 on the fourth clamping plate 133.

[0373] In this embodiment, the third locking member can pass through the sixth waist-shaped hole and the third mounting hole to lock the third guiding plate 161 on the third clamping plate 132. Since the waist-shaped hole is arranged on the third guiding plate 161, the position of the third guiding plate 161 on the third clamping plate 132 can be adjusted before the third locking member is locked on the third guiding plate 161, so as to facilitate the adjustment of the third guiding plate 161 to a position suitable for guiding the second side edge.

[0374] Similarly, the fourth locking member can pass through the seventh waist-shaped hole and the fourth mounting hole to lock the fourth guiding plate 162 on the fourth clamping plate 133. Since the waist-shaped hole is arranged on the fourth guiding plate 162, the position of the fourth guiding plate 162 on the fourth clamping plate 133 can be adjusted before the fourth locking member is locked on the fourth guiding plate 162, so as to facilitate the adjustment of the fourth guiding plate 162 to a position suitable for guiding the second side edge.

[0375] Exemplarily, the third locking member and the fourth locking member are bolts, and the third mounting hole and the fourth mounting hole are threaded holes.

[0376] In combination Figure 2 and Figure 3 As shown in FIG. 1, in a possible embodiment, the feeding device 100 further comprises a first positioning body 170 and a pushing assembly 180. The first positioning body 170 is arranged on the feeding table 110. The pushing assembly 180 is used to push the first to-be-welded cavity 810 towards the first positioning body 170.

[0377] In this embodiment, the first positioning body 170 is arranged on the feeding table 110. The pushing assembly 180 can push the first to-be-welded cavity 810, so that the first to-be-welded cavity 810 is pushed to abut against the first positioning body 170, thereby realizing the positioning of the first to-be-welded cavity 810.

[0378] When the first to-be-welded cavity 810 is placed on the feeding table 110, although the first and second correcting assemblies 120 and 130 can correct the shape of the first to-be-welded body, the first to-be-welded cavity 810 can deviate from the feeding position, so that the first material taking assembly 140 can not accurately take away the first to-be-welded cavity 810. The first positioning body 170 serves as a reference part, and the pushing assembly 180 pushes the first to-be-welded cavity 810 towards the first positioning body 170. When the first to-be-welded cavity 810 contacts the first positioning body 170, it indicates that the first to-be-welded cavity 810 is moved to the position, and at this time, the first material taking assembly 140 can accurately take away the first to-be-welded cavity 810.

[0379] In combination with Figure 2 and Figure 3 shown in a possible embodiment, the pushing assembly 180 comprises a third power part 181 and a pushing piece 182. The third power part 181 is arranged on the feeding table 110. The pushing piece 182 is arranged on the third power part 181. The third power part 181 is used to drive the pushing piece 182 to move, so that the pushing piece 182 pushes the first to-be-welded cavity 810.

[0380] In this embodiment, the third power part 181 is installed on the feeding table 110. The third power part 181 can drive the pushing piece 182 to move, so that the pushing piece 182 pushes the first to-be-welded cavity 810 towards the first positioning body 170.

[0381] When the first side edge extends between the first and second clamping plates 122 and 123, and the second side edge extends between the third and fourth clamping plates 132 and 133, the third power part 181 pushes the first to-be-welded cavity 810. When the first to-be-welded cavity 810 contacts the first positioning body 170, it indicates that the first to-be-welded cavity 810 is moved to the position, and at this time, the first material taking assembly 140 can accurately take away the first to-be-welded cavity 810.

[0382] In this embodiment, the third driving force is a pneumatic cylinder. In other embodiments, the third power part 181 can also be a combination structure of a motor and a gear, etc.

[0383] In combination with Figure 2 and Figure 3 shown in a possible embodiment, the feeding device 100 further comprises first and second positioning pins 111 and 112. The first and second positioning pins 111 and 112 are arranged on the feeding table 110. The first side edge is provided with a first insertion hole, and the second side edge is provided with a second insertion hole. In the case that the first to-be-welded cavity 810 is pushed to contact the first positioning body 170, the first and second positioning pins 111 and 112 are respectively inserted into the first and second insertion holes.

[0384] In this embodiment, when the first cavity 810 to be welded moves to the case where the first positioning body 170 is in contact, it is indicated that the first cavity 810 to be welded is moved into position. When the first cavity 810 to be welded is moved into position, the first positioning pin 111 is inserted into the first insertion hole of the first side edge, and the second positioning pin 112 is inserted into the second insertion hole of the second side edge. The first positioning pin 111 and the second positioning pin 112 can keep the first cavity 810 to be welded in a regular cavity shape, avoid the first cavity 810 to be welded from being deformed again due to abnormality of the first correction assembly 120 and the second correction assembly 130, and ensure that the first material taking assembly 140 can transfer the regular first cavity 810 to be welded. By arranging the first positioning pin 111 and the second positioning pin 112, the stability of the first cavity 810 to be welded in a regular shape can be improved.

[0385] When the first cavity 810 to be welded is not moved into position, the first positioning pin 111 and the second positioning pin 112 are in a retracted state, and when the first cavity 810 to be welded is moved into position, the first positioning pin 111 and the second positioning pin 112 are extended out of the material loading table 110.

[0386] The movement of the first positioning pin 111 and the second positioning pin 112 can be driven by a driving member such as a pneumatic cylinder or an electric motor.

[0387] In combination with Figure 2 and Figure 4 In a possible embodiment, the feeding device 100 further comprises a first sensor 113 arranged on the material loading table 110, and the first sensor 113 is configured to detect the position of the first cavity 810 to be welded, so that the first positioning pin 111 and the second positioning pin 112 act according to the detection signal of the first sensor 113.

[0388] In this embodiment, the first sensor 113 can detect the position of the first cavity 810 to be welded, and the first positioning pin 111 and the second positioning pin 112 act according to the detection signal of the first sensor 113. When the first sensor 113 does not detect that the first cavity 810 to be welded is moved into position, the first positioning pin 111 and the second positioning pin 112 do not act, so as to avoid interference of the first positioning pin 111 and the second positioning pin 112 with the movement of the first cavity 810 to be welded. When the first cavity 810 to be welded is moved into position, the first sensor 113 detects that the first cavity 810 to be welded is moved into position, and the first positioning pin 111 and the second positioning pin 112 act and are respectively inserted into the first insertion hole and the second insertion hole.

[0389] For example, the first sensor 113 can be a position sensor or an infrared sensor.

[0390] In combination with Figure 2 and Figure 4As shown, in a possible embodiment, the first material taking assembly 140 comprises a first guide rail assembly, a fourth power unit 142, a fifth power unit 143, a sixth suction assembly 144 and a seventh suction assembly 145.

The sixth suction assembly 144 is configured to suck the first side edge, and the seventh suction assembly 145 is configured to suck the second side edge.

[0391] In this embodiment, when the first welding cavity 810 needs to be transferred, the first guide rail assembly drives the fourth power unit 142 to move above the first welding cavity 810, the fourth power unit 142 drives the fifth power unit 143 to descend, and the fifth power unit 143 drives the sixth suction assembly 144 and the seventh suction assembly 145 to extend into the first welding cavity 810. The sixth suction assembly 144 sucks the first side edge, and the seventh suction assembly 145 sucks the second side edge. In the process of transferring the first welding cavity 810, the sixth suction assembly 144 and the seventh suction assembly 145 ensure that the distance between the first side edge and the second side edge does not change easily.

[0392] After the sixth suction assembly 144 sucks the first side edge and the seventh suction assembly 145 sucks the second side edge, the first correcting assembly 120 stops clamping the first side edge, the second correcting assembly 130 stops clamping the second side edge, the fourth power unit 142 drives the fifth power unit 143 to ascend, and the second guide rail assembly 541 drives the fourth power unit 142 to move, thereby realizing the feeding process.

[0393] In this embodiment, the fifth power unit 143 can be a pneumatic clamp jaw, or the fifth power unit 143 can be composed of two air cylinders, and the two air cylinders are configured to drive the sixth suction assembly 144 and the seventh suction assembly 145 to act, respectively.

[0394] In combination with Figure 2 and Figure 4 As shown, in a possible embodiment, the sixth suction assembly 144 comprises a first mounting frame 1441, a sixth power unit 1442 and a first suction member 1443.

The sixth power unit 1442 is configured to drive the two first suction members 1443 to approach or move away from each other.

[0395] In this embodiment, the fifth power part 143 can drive the first mounting frame 1441 to move laterally, the sixth power part 1442 is installed on the first mounting frame 1441, and the first mounting frame 1441 can drive the sixth power part 1442 to move, so that the sixth power part 1442 can extend into or out of the first welding cavity 810.

[0396] Two first suction members 1443 are installed on the sixth power part 1442, and the sixth power part 1442 can drive the two first suction members 1443 to move, so that the two first suction members 1443 can approach or move away from each other.

[0397] When it is necessary to transfer the first welding cavity 810, the fifth power part 143 drives the sixth suction assembly 144 to extend into the first welding cavity 810, and the sixth power part 1442 drives the two first suction members 1443 to move away from each other, so that the two first suction members 1443 respectively suck the first side edge and the second side edge.

[0401] Two second suction members are installed on the seventh power part, and the seventh power part can drive the two second suction members to move, so that the two second suction members can approach or move away from each other.

The third cylinder 1423 is configured to drive the support plate 1424 and the fifth power unit 143 to ascend or descend.

[0409] In this embodiment, the mounting plate 1421 is mounted on the first guide rail assembly, and the second cylinder 1422 is mounted on the mounting plate 1421. The mounting plate 1421 bears the second cylinder 1422. The third cylinder 1423 is mounted on the second cylinder 1422, and the second cylinder 1422 can drive the third cylinder 1423 to ascend or descend. The support plate 1424 is mounted on the third cylinder 1423, and the fifth power unit 143 is mounted on the support plate 1424. The third cylinder 1423 can drive the support plate 1424 and the fifth power unit 143 to ascend or descend.

[0410] When the piston rod of the second cylinder 1422 is extended, the third cylinder 1423, the support plate 1424, and the fifth power unit 143 descend. At this time, the support plate 1424 and the fifth power unit 143 are in a first stage of descent. When the piston rod of the third cylinder 1423 is extended, the support plate 1424 and the fifth power unit 143 descend. At this time, the support plate 1424 and the fifth power unit 143 are in a second stage of descent. By arranging the combination of the second cylinder 1422 and the third cylinder 1423, the support plate 1424 and the fifth power unit 143 have two strokes, which can improve the convenience of loading and unloading.

[0411] In addition, since the combination of the second cylinder 1422 and the third cylinder 1423 forms a two-stroke process, during the feeding process of the first material handling component 140, the piston rods of the second cylinder 1422 and the third cylinder 1423 can be set to extend, thereby placing the adsorbed first welding cavity 810 at the lower process position. After placement, the piston rod of the second cylinder 1422 or the third cylinder 1423 retracts, which allows the support plate 1424 and the fifth power unit 143 to leave the feeding station, that is, the descent becomes a two-stroke process and the ascent becomes a single-stroke process. By shortening the movement stroke, the feeding efficiency is effectively improved.

[0412] Combination Figure 5 and Figure 5 As shown, in one possible embodiment, the first material handling component 140 further includes an eighth adsorption component 146, which is disposed in the fourth power unit 142 and is used to adsorb the first cavity to be welded 810.

[0413] In this embodiment, the eighth adsorption component 146 is disposed on the fourth power unit 142, which can drive the eighth adsorption component 146 to rise or fall. The eighth adsorption component 146 can adsorb the outer surface of the first cavity to be welded 810, preventing the first cavity to be welded 810 from separating from the first material handling component 140 during the feeding process, which helps to improve the stability of the feeding process.

[0414] The eighth adsorption component 146 includes a rubber pneumatic suction nozzle, which can adsorb the first cavity 810 to be welded.

[0415] like Figure 6 As shown, in one possible embodiment, the material transfer device 300 includes a first adsorption component 310 and a support component 320. The first adsorption component 310 is used to pick up the second cavity to be welded 820 and move the second cavity to be welded 820; the support component 320 is disposed on the first adsorption component 310. When the first adsorption component 310 picks up the second cavity to be welded 820, a portion of the support component 320 extends into the second cavity to be welded 820, and the support component 320 is used to push the inner wall of the second cavity to be welded 820.

[0416] When the material transfer device 300 provided in this embodiment needs to transfer the second cavity to be welded 820, the first adsorption component 310 drives the support component 320 to move to the vicinity of the second cavity to be welded 820, and a part of the support component 320 extends into the second cavity to be welded 820.

[0417] The second cavity to be welded 820 can be a three-dimensional structure with four sides. The second cavity to be welded 820 needs to be welded to the front plate 910 and the rear plate 930 to form a complete cooking cavity.

[0418] When the second to-be-welded cavity 820 needs to be welded with the front plate 910, it is necessary to ensure that the two adjacent sides in the second to-be-welded cavity 820 are at right angles, so that the second to-be-welded cavity 820 can be closely attached to the front plate 910. Before the front plate 910 is welded, the second to-be-welded cavity 820 can be deformed, resulting in an acute or obtuse angle between the two adjacent sides. A part of the support assembly 320 extending into the second to-be-welded cavity 820 can push the two opposite inner walls of the second to-be-welded cavity 820. With the pushing of the support assembly 320, the two opposite inner walls of the second to-be-welded cavity 820 move away from each other. With the two inner walls moving away from each other, the included angle between the two adjacent sides of the second to-be-welded cavity 820 also changes, and when the support assembly 320 moves to the limit position, the included angle between the two adjacent sides of the second to-be-welded cavity 820 is at right angles. The first adsorption assembly 310 adsorbs the outer side wall of the second to-be-welded cavity 820, so that the second to-be-welded cavity 820 is not easy to shake, which is beneficial to the pushing of the inner wall of the second to-be-welded cavity 820 by the support assembly 320.

[0419] The movement of the support assembly 320 to the limit position refers to that, for the second to-be-welded cavity 820 with the two adjacent sides at right angles, a part of the support assembly 320 located in the second to-be-welded cavity 820 just contacts the two opposite inner walls.

[0420] The first adsorption assembly 310 can move the second to-be-welded cavity 820 to the welding position. During the movement of the second to-be-welded cavity 820 by the first adsorption assembly 310, the support assembly 320 supports the two adjacent inner walls of the second to-be-welded cavity 820, so that the two adjacent sides of the second to-be-welded cavity 820 placed in the welding position are at right angles. When the second to-be-welded cavity 820 is welded with the front plate 910, the second to-be-welded cavity 820 can be closely attached to the front plate 910, avoiding poor welding and improving the processing precision of the cooking cavity.

[0421] The first adsorption assembly 310 transfers the second to-be-welded cavity 820, realizing automatic handling of the second to-be-welded cavity 820 and saving the workload of the staff in handling the second to-be-welded cavity 820.

[0422] The support assembly 320 operates the deformed second to-be-welded cavity 820, ensuring that the second to-be-welded cavity 820 in the welding position is a standard structure without deformation, and the staff does not need to pull the deformed second to-be-welded cavity 820, further saving the workload of the staff. Moreover, the first adsorption assembly 310 automatically pulls the second to-be-welded cavity 820, so that the second to-be-welded cavity 820 can be accurately placed in the welding position, which is beneficial to further improving the welding precision of the second to-be-welded cavity 820 and the front plate 910.

[0423] In combination Figure 5 And Figure 6 As shown in FIG. 12, in one possible implementation, the support assembly 320 includes a fixed plate 321, a power member, a first support member 323, and a second support member. The fixed plate 321 is arranged on the first adsorption assembly 310. The power member is arranged on the fixed plate 321. The first support member 323 and the second support member are arranged on the power member. The power member is configured to drive the first support member 323 and the second support member to move, so that the first support member 323 and the second support member push two opposite inner walls in the second cavity 820 to be welded.

[0424] In this implementation, the fixed plate 321 is mounted on the first adsorption assembly 310, and the first adsorption assembly 310 can drive the fixed plate 321 to move. The power member is mounted on the fixed plate 321, so that the fixed plate 321 can drive the power member to move. The first support member 323 and the second support member are mounted on the power member, and the power member can drive the first support member 323 and the second support member to move closer to or farther away from each other.

[0425] When the second cavity 820 to be welded needs to be transferred, the first adsorption assembly 310 drives the fixed plate 321 to move, so that the fixed plate 321 drives the power member, the first support member 323, and the second support member to extend into the second cavity 820 to be welded. The first adsorption assembly 310 adsorbs one side of the outer wall of the second cavity 820 to be welded. The adsorbed outer wall serves as a reference part. When the first support member 323 and the second support member push the two opposite inner walls in the second cavity 820 to be welded, the second cavity 820 to be welded is not easy to move relative to the first adsorption assembly 310.

[0426] When the first support member 323 and the second support member push the two opposite inner walls in the second cavity 820 to be welded, the two opposite inner walls gradually move away from each other. As the two inner walls move away from each other, the included angle between the two adjacent sides in the second cavity 820 to be welded also changes. When the support assembly 320 moves to the limit position, the included angle between the two adjacent sides in the second cavity 820 to be welded is a right angle. When the second cavity 820 to be welded is welded with the front plate 910, the second cavity 820 to be welded can be in close contact with the front plate 910, so that the welding failure is avoided, and the processing precision of the cooking cavity is improved.

[0427] In combination Figure 5 And Figure 6 As shown in FIG. 12, in one possible implementation, the power member includes a first cylinder 3221, a first connecting plate 3222, and a second connecting plate. The first connecting plate 3222 is arranged on the first cylinder 3221, and the first support member 323 is arranged on the first connecting plate 3222. The second connecting plate is arranged on the first cylinder 3221, and the second support member is arranged on the second connecting plate.

[0428] In this embodiment, the first cylinder 3221 is capable of driving the first connecting plate 3222 and the second connecting plate to move, so that the first connecting plate 3222 drives the first support 323 to move, and the second connecting plate drives the second support to move.

[0429] The number of the first cylinder 3221 can be two, one first cylinder 3221 is connected with the first connecting plate 3222, and the other first cylinder 3221 is connected with the second connecting plate.

[0430] In order to ensure that the first support 323 and the second support can stably push the inner wall of the second to-be-welded cavity 820, it is necessary to set the first support 323 and the second support to have a large contact area with the inner wall of the second to-be-welded cavity 820. The assembly of the large-volume first support 323 and the second support with the first cylinder 3221 is difficult, and therefore a first connecting plate 3222 can be arranged between the first cylinder 3221 and the first support 323 as an intermediate component to improve the assembly convenience of the power component and the first support 323. Similarly, a second connecting plate is arranged between the first cylinder 3221 and the second support.

[0431] In combination with Figure 5 and Figure 6 It is shown that in a possible embodiment, the first support 323 is detachably connected to the first connecting plate 3222; and / or the second support is detachably connected to the second connecting plate.

[0432] In this embodiment, when the first connecting plate 3222 or the first support 323 is damaged, the first support 323 can be detached from the first connecting plate 3222, so that the first connecting plate 3222 or the first support 323 can be replaced separately, which is beneficial to reduce the maintenance cost.

[0433] Similarly, when the second connecting plate or the second support is damaged, the second support can be detached from the second connecting plate, so that the second connecting plate or the second support can be replaced separately, which is beneficial to reduce the maintenance cost.

[0434] In combination with Figure 5 and Figure 6As shown, in a possible embodiment, the support assembly 320 further comprises: a first waist-shaped hole 325, a first through hole, a first locking member, a second waist-shaped hole, a second through hole and a second locking member, the first waist-shaped hole 325 is arranged on the first connecting plate 3222, and the first through hole is arranged on the first support member 323; the first locking member passes through the first waist-shaped hole 325 and the first through hole to lock the first support member 323 to the first connecting plate 3222. The second waist-shaped hole is arranged on the second connecting plate, the second through hole is arranged on the second support member, and the second locking member passes through the second waist-shaped hole and the second through hole to lock the second support member to the second connecting plate.

[0435] In this embodiment, the first waist-shaped hole 325 is arranged on the first connecting plate 3222, the first through hole is arranged on the first support member 323, and the first locking member can pass through the first waist-shaped hole 325 and the first through hole. Before the first locking member is locked to the first connecting plate 3222, the first waist-shaped hole 325 and the first locking member can move relatively, so that the relative position of the first support member 323 and the first connecting plate 3222 can be adjusted, so as to adjust the first support member 323 to a position suitable for supporting the inner wall of the second cavity to be welded 820.

[0436] The second waist-shaped hole is arranged on the second connecting plate, the second through hole is arranged on the second support member, and the second locking member can pass through the second waist-shaped hole and the second through hole. Before the second locking member is locked to the second connecting plate, the second waist-shaped hole and the second locking member can move relatively, so that the relative position of the second support member and the second connecting plate can be adjusted, so as to adjust the second support member to a position suitable for supporting the inner wall of the second cavity to be welded 820.

[0437] In combination Figure 5 And Figure 6 As shown, in a possible embodiment, the thickness of the first connecting plate 3222 is greater than the thickness of the first support member 323; and / or the thickness of the second connecting plate is greater than the thickness of the second support member.

[0438] In this embodiment, the thickness of the first connecting plate 3222 is greater than the thickness of the first support member 323, so that the first connecting plate 3222 is not easy to break, and the first connecting plate 3222 can stably support the first support member 323.

[0439] The thickness of the second connecting plate is greater than the thickness of the second support member, so that the second connecting plate is not easy to break, and the second connecting plate can stably support the second support member.

[0440] In combination Figure 5 And Figure 6As shown in the possible embodiment, the fixing plate 321 comprises a first plate body 3211 and a second plate body 3212, the first plate body 3211 is arranged on the first adsorption assembly 310; the power member is arranged on the second plate body 3212, and the width of the second plate body 3212 is greater than that of the first plate body 3211.

[0441] In the embodiment, the first plate body 3211 is installed on the first adsorption assembly 310, and the second plate body 3212 is connected with the power member. Since the width of the second plate body 3212 is greater than that of the first plate body 3211, the second plate body 3212 has higher structural stability, thereby ensuring the connection stability of the second plate body 3212 and the power member.

[0442] By reducing the width of the first plate body 3211, the weight of the fixing plate 321 is reduced, thereby reducing the overall weight of the supporting assembly 320, and the running stability of the material transfer device 300 is improved.

[0443] In a possible embodiment, the supporting assembly 320 is detachably connected to the first adsorption assembly 310.

[0444] In the embodiment, the supporting assembly 320 can be detached from the first adsorption assembly 310, when the supporting assembly 320 or the first adsorption assembly 310 is damaged, the supporting assembly 320 can be detached from the first adsorption assembly 310, so as to facilitate the individual maintenance or replacement of the supporting assembly 320 or the first adsorption assembly 310, thereby reducing the maintenance cost of the material transfer device 300.

[0445] In combination with Figure 5 and Figure 6 As shown in the possible embodiment, the first adsorption assembly 310 comprises a suction member 311 and a manipulator 312, the suction member 311 is used for sucking the second to-be-welded cavity 820, and the supporting assembly 320 is arranged on the suction member 311; the suction member 311 is arranged on the manipulator 312, and the manipulator 312 is used for driving the suction member 311 to move.

[0446] In the embodiment, the supporting assembly 320 is installed on the suction member 311, and the suction member 311 can adsorb the second to-be-welded cavity 820, so that the first adsorption assembly 310 can drive the second to-be-welded cavity 820 to move. The suction member 311 is installed on the manipulator 312, and the manipulator 312 has a plurality of rotating shafts, so that the manipulator 312 can flexibly drive the suction member 311 and the supporting assembly to move.

[0447] When the second cavity to be welded needs to be transferred, the manipulator 312 first drives the supporting assembly 320 to extend into the second cavity to be welded, and then adjusts the position of the suction member 311, so that the supporting assembly 320 can support the inner wall of the second cavity to be welded, and the suction member 311 is in contact with the outer wall of the second cavity to be welded. By moving the supporting assembly 320 and the suction member 311 by the manipulator 312, the stability during the feeding process can be improved.

[0448] In a possible embodiment, the suction member 311 is rotationally connected to the manipulator 312.

[0449] In this embodiment, the suction member 311 can rotate relative to the manipulator 312, so that the manipulator 312 can drive the suction member 311 to rotate. By driving the suction member 311 to rotate, the manipulator 312 can adjust the relative position of the suction member 311 and the second cavity to be welded, which can facilitate the supporting assembly to extend into the second cavity to be welded and adjust the position of the suction member 311 to adsorb the second cavity to be welded, and improve the flexibility during the feeding process. The position of the second cavity to be welded does not need to be adjusted by the staff.

[0450] In combination with Figure 5 and Figure 6 In a possible embodiment, the suction member 311 includes a carrying plate 3111 and at least two suction parts 3112, and the supporting assembly 320 is arranged on the carrying plate 3111. The at least two suction parts 3112 are arranged on the carrying plate 3111, and the suction part 3112 is used to suck the second cavity to be welded.

[0451] In this embodiment, the carrying plate 3111 plays a carrying role for the supporting assembly 320 and the at least two suction parts 3112. By increasing the number of suction parts 3112, the stability of the suction member 311 in sucking the second cavity to be welded can be improved, the suction member 311 can be prevented from being separated from the second cavity to be welded, and the stability during the transfer of the second cavity to be welded can be improved.

[0452] In a possible embodiment, the suction part 3112 includes a connecting rod, an elastic member, a sliding rod and a suction nozzle. The connecting rod is arranged on the carrying plate 3111, and the connecting rod is provided with a sliding cavity. The elastic member is arranged in the sliding cavity. The sliding rod is slidably connected to the sliding cavity, and the sliding rod is in abutment with the elastic member. The suction nozzle is arranged on the sliding rod.

[0453] In this embodiment, the connecting rod is internally provided with a sliding cavity, and the sliding rod can slide in the sliding cavity, so that the sliding rod can extend into or out of the sliding cavity, and thus the length of the sliding rod extending out of the sliding cavity can be adjusted.

[0454] An elastic element is installed inside the sliding cavity. The sliding rod is in contact with the elastic element. When the sliding rod moves into the sliding cavity, the elastic element is compressed.

[0455] The suction nozzle is located on the sliding rod. The suction nozzle can be adsorbed onto the outer surface of the second cavity to be welded 820. When the suction assembly picks up the second cavity to be welded 820, the sliding rod can slide relative to the connecting rod, so that the suction nozzle plays a buffering role, avoiding collision between the suction nozzle and the second cavity to be welded 820 and causing damage, which is beneficial to improving the structural stability of the first adsorption assembly 310.

[0456] For example, the suction nozzle can be made of rubber.

[0457] Combination Figure 7 and Figure 8 As shown, in one possible embodiment, the suction member 311 further includes a locking hole 3116, which is provided on the support plate 3111, and the suction part 3112 is detachably connected to the locking hole 3116.

[0458] In this embodiment, the suction part 3112 can be detached from the locking hole 3116, so the suction part 3112 can be detached from the support plate 3111. When the suction part 3112 is damaged, the suction part 3112 can be maintained and replaced separately, which helps to reduce the maintenance cost of the suction part 311.

[0459] For example, a portion of the connecting rod passes through the locking hole 3116, and the portion of the connecting rod passing through the locking hole 3116 is threaded. A nut is used to connect with the thread on the connecting rod, thereby locking the connecting rod to the support plate 3111.

[0460] In one possible embodiment, the number of locking holes 3116 is greater than the number of suction portions 3112.

[0461] In this embodiment, the suction part 3112 can be connected to any locking hole 3116 on the support plate 3111, thereby adjusting the position of the suction part 3112 on the support plate 3111. The suction part 3112 can be adjusted to a position suitable for suctioning the second cavity 820 to be welded. For example, when the second cavity 820 to be welded has a through hole structure, the position of the suction part 3112 can be adjusted to avoid the through hole structure, which helps to improve the adsorption stability of the suction part 3112 on the second cavity 820 to be welded.

[0462] Combination Figure 7 and Figure 8As shown, in one possible implementation, the front plate welding device 400 includes a first rack 410, a first transfer assembly 420, a first positioning assembly 430, a second transfer assembly 440, a second positioning assembly 450, and a first welding assembly 460; the first transfer assembly 420 is arranged on the first rack 410, and is configured to drive the second to-be-welded cavity 820 to move to the first welding position; the first positioning assembly 430 is arranged on the transfer assembly, and is configured to position the second to-be-welded cavity 820; the second transfer assembly 440 is arranged on the first rack 410, and is configured to drive the front plate 910 to move to the first welding position; the second positioning assembly 450 is arranged on the first rack 410, and is located at the first welding position, and is configured to position the front plate 910; and the first welding assembly 460 is arranged on the first rack 410, and is configured to weld the second to-be-welded cavity 820 and the front plate 910.

[0463] The front plate welding device 400 provided in this embodiment can drive the second to-be-welded cavity 820 to move through the first transfer assembly 420, and the first positioning assembly 430 arranged on the first transfer assembly 420 can position the second to-be-welded cavity 820. Under the positioning action of the first positioning assembly 430, the second to-be-welded cavity 820 is less likely to move relative to the first transfer assembly 420, so that the first positioning assembly 430 can stably drive the second to-be-welded cavity 820 to move to the first welding position.

[0464] The second to-be-welded cavity 820 can have a three-dimensional structure with four sides, and needs to be welded with the front plate 910 and the rear plate 930 to form a complete cooking cavity.

[0465] When the second to-be-welded cavity 820 and the front plate 910 need to be welded, the first transfer assembly 420 drives the second to-be-welded cavity 820 to move to the first welding position, and the first positioning assembly 430 can position the second to-be-welded cavity 820 not only during the movement, but also when the second to-be-welded cavity 820 moves to the first welding position. During the movement and welding, the second to-be-welded cavity 820 is less likely to move relative to the first transfer assembly 420, which is conducive to ensuring the stability and accuracy of the welding process.

[0466] The second transfer assembly 440 can drive the front plate 910 to move to the first welding position, so that the front plate 910 can be automatically transferred to the first welding position, and the first welding assembly 460 located near the first welding position can weld the front plate 910 and the second to-be-welded cavity 820 to automatically complete the welding process.

[0467] The second positioning assembly 450 is arranged at the first welding position and can position the front plate 910 moved to the first welding position, so that the front plate 910 is accurately positioned to the position to be welded. Moreover, under the positioning action of the second positioning assembly 450, the front plate 910 is not prone to shaking, so that the front plate 910 and the second cavity to be welded 820 can stably complete the welding process.

[0468] The first transfer assembly 420 drives the second cavity to be welded 820 to move, and the second transfer assembly 440 drives the front plate 910 to move, which automatically transfers the second cavity to be welded 820 and the front plate 910, saving the work of the staff to carry the second cavity to be welded 820 and the front plate 910.

[0469] The first positioning assembly 430 positions the second cavity to be welded 820, and the second positioning assembly 450 positions the front plate 910, which automatically realizes the transfer of the second cavity to be welded 820 and the front plate 910, saving the work of the staff to position the second cavity to be welded 820 and the front plate 910. Moreover, compared with the manual positioning mode, the positioning mode of the mechanical structure can improve the positioning accuracy, the first welding assembly 460 can accurately weld the second cavity to be welded 820 and the front plate 910, avoiding the occurrence of poor welding, which is beneficial to improve the processing precision of the cooking cavity.

[0470] In combination with Figure 8 and Figure 9 shown, in a possible embodiment, the first positioning assembly 430 includes a first support rib 431 and a first driving member 432, which is arranged at the first transfer assembly 420, and the first driving member 432 is used to drive the first support rib 431 to move, so that the first support rib 431 abuts against the plurality of inner walls of the second cavity to be welded 820.

[0471] In this embodiment, when the second cavity to be welded 820 is placed on the first transfer assembly 420, the first driving member 432 drives the first support rib 431 to move, so that the first support rib 431 can contact the plurality of inner walls in the second cavity to be welded 820.

[0472] The second cavity to be welded 820 has four side walls, and the first driving member 432 can drive the first support rib 431 to contact the four side walls in the second cavity to be welded 820. The first support rib 431 supports the inner walls of the second cavity to be welded 820, thereby fixing the second cavity to be welded 820 to the first transfer assembly 420.

[0473] Since the first support rib 431 can be in contact with the plurality of side walls in the second to-be-welded cavity 820, the first support rib 431 can push the plurality of side walls in the second to-be-welded cavity 820, so as to adjust the position of the second to-be-welded cavity 820 on the first transfer assembly 420, and realize the function of positioning the second to-be-welded cavity 820. When the first transfer assembly 420 moves the second to-be-welded cavity 820 to the first welding position, the position of the second to-be-welded cavity 820 does not need to be adjusted, which is beneficial to realize the precise welding of the second to-be-welded cavity 820 and the front plate 910.

[0474] When the second to-be-welded cavity 820 is not welded with the front plate 910, the second to-be-welded cavity 820 is easy to deform, that is, the included angle between two adjacent side walls in the second to-be-welded cavity 820 can be an acute angle or an obtuse angle. By supporting the plurality of side walls in the second to-be-welded cavity 820 through the first support rib 431, the second to-be-welded cavity 820 is supported as a regular cavity structure, that is, the included angle between two adjacent side walls in the second to-be-welded cavity 820 is 90°. When the second to-be-welded cavity 820 is welded with the front plate 910, the second to-be-welded cavity 820 can be in close contact with the front plate 910, so as to avoid the occurrence of poor welding, and is beneficial to improve the processing precision of the cooking cavity.

[0475] The first support rib 431 supports the second to-be-welded cavity 820, so that the second to-be-welded cavity 820 is not easy to shake relative to the first transfer assembly 420, which is beneficial to improve the stability when the second to-be-welded cavity 820 is transferred.

[0476] In combination with FIGS. 4, 5, 6 and 7, Figure 7 and Figure 10 In a possible embodiment, the second to-be-welded cavity 820 includes a first inner wall, a second inner wall, a third inner wall and a fourth inner wall; the first driving member 432 includes a first sub-driving part and a second sub-driving part; the first support rib 431 includes a first support part 4311 and a second support part 4312 connected with each other, and a third support part 4313 and a fourth support part 4314 connected with each other, the first support part 4311 and the second support part 4312 are arranged at the first sub-driving part, and the first support part 4311 and the second support part 4312 are respectively used for abutting against the first inner wall and the second inner wall; the third support part 4313 and the fourth support part 4314 are arranged at the second sub-driving part, and the third support part 4313 and the fourth support part 4314 are respectively used for abutting against the third inner wall and the fourth inner wall.

[0477] In this embodiment, the first support rib 431 comprises a first support part 4311, a second support part 4312, a third support part 4313 and a fourth support part 4314, which are respectively used to contact the first inner wall, the second inner wall, the third inner wall and the fourth inner wall in the second cavity to be welded 820. The first support part 4311 and the second support part 4312 are connected, and the first support part 4311 and / or the second support part 4312 are arranged on the first sub-driving part, so that the first sub-driving part can drive the first support part 4311 and the second support part 4312 to move. The third support part 4313 and the fourth support part 4314 are connected, and the third support part 4313 and / or the fourth support part 4314 are arranged on the second sub-driving part, so that the second sub-driving part can drive the third support part 4313 and the fourth support part 4314 to move.

[0478] The first sub-driving part and the second sub-driving part can be arranged to be perpendicular to each other in the axial direction. For example, the first sub-driving part drives the first support part 4311 to push the first inner wall, and as the first inner wall is pushed, the third inner wall will be in contact with the third support part 4313. The second sub-driving part drives the fourth support part 4314 to push the fourth inner wall, and as the fourth inner wall is pushed, the second inner wall will be in contact with the first support plate 1424. In this way, the positioning and structural correction of the second cavity to be welded 820 are realized.

[0479] Of course, in other embodiments, four sub-driving parts can be used to respectively drive the first support part 4311, the second support part 4312, the third support part 4313 and the fourth support part 4314 to move.

[0480] The first support part 4311 and the second support part 4312 are perpendicular to each other, and the third support part 4313 and the fourth support part 4314 are perpendicular to each other.

[0481] For example, in this embodiment, the first sub-driving part and the second sub-driving part can both be air cylinders. In other embodiments, the first sub-driving part and the second sub-driving part can also be a combination of a motor and a gear.

[0482] In combination with Figure 10 and Figure 10As shown, in one possible embodiment, the second positioning component 450 includes: a first positioning part 451, a second positioning part 452, a third positioning part 453, and a fourth positioning part 454. The second positioning part 452 is used to push the front plate 910 toward the first positioning part 451. The third positioning part 453 and the fourth positioning part 454 are disposed on the first frame 410 and are used to push the front plate 910. The first positioning part 451, the second positioning part 452, the third positioning part 453, and the fourth positioning part 454 are used to contact different sides of the front plate 910.

[0483] In this embodiment, the second transfer component 440 moves the front plate 910 to the first welding position, whereby the front plate 910 can be placed on top of the second welding cavity 820 located at the loading position. Before welding the second welding cavity 820 and the front plate 910, the second positioning part 452 pushes the front plate 910, causing it to move towards the first positioning part 451, thus pushing the front plate 910 to a position in contact with the first positioning part 451, achieving the first-level positioning. The third positioning part 453 and the fourth positioning part 454 push the other two side walls of the front plate 910, centering the front plate 910. When the third positioning part 453 and the fourth positioning part 454 simultaneously contact the front plate 910, the second-level positioning of the front plate 910 is achieved. The first positioning part 451, the second positioning part 452, the third positioning part 453 and the fourth positioning part 454 position the front plate 910 to the welding position. At this time, the front plate 910 and the second cavity to be welded 820 are aligned with each other and fit tightly together, which avoids the occurrence of poor welding and helps to improve the processing accuracy of the cooking cavity.

[0484] like Figure 10 As shown, in one possible embodiment, the first positioning part 451 includes: a first positioning body 4511 and a second driving member 4512. The first positioning body 4511 is used to abut against the front panel 910. The first positioning body 4511 is disposed on the second driving member 4512, and the second driving member 4512 is used to push the first positioning body 4511 closer to or away from the front panel 910.

[0485] In this embodiment, the first positioning body 4511 serves as a reference part for positioning the front plate 910. When the front plate 910 needs to be positioned, the second positioning part 452 pushes the front plate 910 toward the first positioning body 4511.

[0486] The second driving member 4512 can drive the first positioning body 4511 to move, so that the first positioning body 4511 can approach or move away from the front plate 910. Specifically, the first positioning body 4511 serves as a reference part. When the front plate 910 is in contact with the first positioning body 4511, the front plate 910 can still not be aligned with the second to-be-welded cavity 820. At this time, the second driving member 4512 needs to drive the second positioning body to move, so as to adjust the position of the second positioning body, thereby improving the positioning accuracy of the front plate 910.

[0487] In addition, after the first welding assembly 460 welds the second to-be-welded cavity 820 and the front plate 910, a third to-be-welded cavity 830 is obtained. The third to-be-welded cavity 830 needs to be transferred to the next station and welded with the rear plate 930.

[0488] When the third to-be-welded cavity 830 needs to be transferred, the second driving member 4512 can drive the first positioning body 4511 to move away from the front plate 910, so as to avoid interference with the transfer process of the third to-be-welded cavity 830.

[0489] Exemplarily, the second driving member 4512 can be a pneumatic cylinder. The second driving member 4512 can also be a combination of a motor and a gear set.

[0490] The second positioning part 452 includes a first cylinder and a second positioning body. The first cylinder is used to drive the second positioning body to approach or move away from the front plate 910.

[0491] The third positioning part 453 includes a second cylinder and a third positioning body. The second cylinder is used to drive the third positioning body to approach or move away from the front plate 910.

[0492] The fourth positioning part 454 includes a third cylinder and a fourth positioning body. The third cylinder is used to drive the fourth positioning body to approach or move away from the front plate 910.

[0493] As shown in the possible embodiment, Figure 10 The first positioning body 4511 includes a third connecting plate 4513 and at least two abutting parts 4514. The third connecting plate 4513 is arranged on the second driving member 4512, and the third connecting plate 4513 is provided with a mounting through hole. The at least two abutting parts 4514 are arranged on the third connecting plate 4513 in a spaced manner, and the abutting part 4514 is used to abut against the front plate 910. The abutting part 4514 is provided with a third waist-shaped hole. A connecting member passes through the third waist-shaped hole and the mounting through hole, so as to lock the abutting part 4514 on the third connecting plate 4513.

[0494] In this embodiment, the third connecting plate 4513 is provided with a mounting through hole, the abutting portion 4514 is provided with a third waist-shaped hole, and the connecting piece can pass through the third waist-shaped hole and the mounting through hole to lock the abutting portion 4514 on the third connecting plate 4513. Since the connecting piece is provided with the third waist-shaped hole, the connecting piece can slide in the third waist-shaped hole, and the position of the abutting portion 4514 on the third connecting plate 4513 can be adjusted before the abutting portion 4514 is locked on the third connecting piece plate, so that the abutting portion 4514 can be adjusted to a position suitable for positioning the front plate 910. By adjusting the position of the abutting portion 4514, the positioning of the front plate 910 can be accurately realized.

[0495] The number of abutting portions 4514 can be at least two, and adjacent two of the at least two abutting portions 4514 are arranged at intervals. By increasing the number of abutting portions 4514, the positioning stability of the front plate 910 can be improved, and the situation that the front plate 910 deviates can be avoided.

[0496] The structures of the second positioning body, the third positioning body and the fourth positioning body can be the same as that of the first positioning body 4511, or the second positioning body, the third positioning body and the fourth positioning body can all be flat plate structures.

[0497] Exemplarily, the connecting piece can be a bolt, and the mounting through hole can be a threaded hole.

[0498] As shown in Figure 7 In a possible embodiment, the second positioning assembly 450 further includes a sliding rail 455 and a third driving piece 456. The sliding rail 455 is arranged on the first rack 410, and the second positioning portion 452 is slidingly connected to the sliding rail 455. The third driving piece 456 is arranged on the first rack 410, and the third driving piece 456 is used to drive the second positioning portion 452 to move, so that the second positioning portion 452 can avoid the second to-be-welded cavity 820 moving towards the first welding position.

[0499] In this embodiment, the second positioning portion 452 is arranged on the sliding rail 455, and the third driving piece 456 can drive the second positioning portion 452 to move, so that the second positioning portion 452 can slide relative to the sliding rail 455.

[0500] When the first transfer assembly 420 drives the second to-be-welded cavity 820 to move towards the first welding position, the third driving piece 456 drives the second positioning portion 452 to move to a position avoiding the second to-be-welded cavity 820, so as to avoid the interference between the second positioning portion 452 and the second to-be-welded cavity 820. When the second to-be-welded cavity 820 moves to the first welding position, the third driving piece 456 pushes the second positioning portion 452, so that the second positioning portion 452 moves to a process of being able to push the second to-be-welded cavity 820, thereby ensuring the stable operation of the front plate welding device 400.

[0501] By setting the slide rail 455 on the first rack 410, the moving stability of the second positioning part 452 is improved.

[0502] Exemplarily, the third driving member 456 can be a cylinder, and in other embodiments, the third driving member 456 can also be a structure of a motor plus a gear set.

[0503] As shown in Figure 8 In a possible embodiment, the second positioning assembly 450 further includes a fourth driving member 457, the fourth driving member 457 is arranged on the first rack 410, the first positioning part 451 is arranged on the fourth driving member 457, and the fourth driving member 457 is used to drive the first positioning part 451 to ascend or descend, so that the first positioning part 451 can avoid the second to-be-welded cavity 820 and the front plate 910 after welding.

[0504] In this embodiment, the first positioning part 451 is arranged on the fourth driving member 457, and the fourth driving member 457 can drive the first positioning part 451 to ascend or descend.

[0505] When the second to-be-welded cavity 820 and the front plate 910 are welded, the third to-be-welded cavity 830 needs to be transferred to the next station, at this time, the fourth driving member 457 drives the first positioning part 451 to descend, so as to avoid the first positioning part 451 from interfering with the third to-be-welded cavity 830, and ensure the operation stability of the front plate welding device 400. When the third to-be-welded cavity 830 is removed, the fourth driving member 457 drives the first positioning part 451 to ascend, so that the first positioning part 451 can continue to position the next to-be-welded front plate 910.

[0506] Exemplarily, the fourth driving member 457 can be a cylinder, and in other embodiments, the fourth driving member 457 can also be a structure of a motor plus a gear set.

[0507] As shown in Figure 9 , Figure 8 and Figure 9 In a possible embodiment, the first transfer assembly 420 includes a support table 421 and a first ball screw 422, the first positioning assembly 430 is arranged on the support table 421; the first ball screw 422 is arranged on the first rack 410, the support table 421 is arranged on the first ball screw 422, and the first ball screw 422 is used to drive the support table 421 to move.

[0508] In this embodiment, the first ball screw 422 can drive the support table 421 to move, so that the support table 421 can drive the first positioning assembly 430 to move.

[0509] The support platform 421 serves as a load-bearing component, and the first positioning component 430 can be mounted on the support platform 421. Compared to supporting the first positioning component 430 on the first ball screw 422, mounting the first positioning component 430 on the support platform 421 improves the ease of installation. Furthermore, the support platform 421 can raise the first positioning component 430 above the first ball screw 422, preventing interference between the second cavity to be welded 820 and the components on the first ball screw 422.

[0510] Combination Figure 7 and Figure 11 As shown, in one possible embodiment, the support platform 421 includes: a first base 4211, a fifth drive member 4212, and a first support seat 4213. The first base 4211 is disposed on the first ball screw 422; the fifth drive member 4212 is disposed on the first base 4211; the first support seat 4213 is disposed on the first base 4211; a first positioning component 430 is disposed on the first support seat 4213; the first support seat 4213 is slidably connected to the first base 4211; and the fifth drive member 4212 is used to drive the first support seat 4213 to rise or fall.

[0511] In this embodiment, the first base 4211 is mounted on the first ball screw 422, the fifth drive member 4212 is mounted on the first base 4211, and the first support seat 4213 is slidably connected to the first base 4211. The fifth drive member 4212 can drive the first support seat 4213 to move, so that the fifth drive member 4212 drives the first support seat 4213 to rise or fall.

[0512] The fifth driving component 4212 can drive the first support base 4213 to rise or fall, thereby indirectly driving the second cavity to be welded 820 to rise or fall. When the support platform 421 moves the second cavity to be welded 820 to the first welding position, the fifth driving component 4212 can drive the first support base 4213 to rise or fall, thereby adjusting the height of the second cavity to be welded 820. This facilitates adjusting the second cavity to be welded 820 to a height suitable for bearing the load of the front plate 910, which helps improve the welding stability of the second cavity to be welded 820 and the front plate 910.

[0513] For example, the fifth drive member 4212 can be a cylinder. In other embodiments, the fifth drive member 4212 can also be a structure of a motor plus a gear set.

[0514] The upper part of the first base 4211 is provided with an outer sleeve, and the bottom of the first support base 4213 is provided with an inner sleeve. The inner sleeve is inserted into the outer sleeve, and the outer sleeve and the inner sleeve are nested together, thereby guiding the lifting and lowering of the first support base 4213.

[0515] CombinationFigure 11 and Figure 11 As shown in FIG. 12, in one possible embodiment, the second transferring assembly 440 includes a second ball screw 441 and a second suction assembly 442. The second ball screw 441 is arranged on the first rack 410. The second suction assembly 442 is arranged on the second ball screw 441. The second ball screw 441 is configured to drive the second suction assembly 442 to move. The second suction assembly 442 is configured to suction the front plate 910.

[0516] In this embodiment, the second ball screw 441 is configured to drive the second suction assembly 442 to move, so that the second suction assembly 442 can transfer the second welding cavity 820 to the first welding position.

[0517] The second suction assembly 442 suctions the front plate 910 to be welded first. Then, the second ball screw 441 drives the second suction assembly 442 to move above the first welding position. The second suction assembly 442 places the front plate 910 to be welded on the second welding cavity 820. Then, the second suction assembly 442 continues to take the next front plate 910 to be welded.

[0518] As shown in FIG. 13, in one possible embodiment, the second suction assembly 442 includes a sixth driving member 4421 and a first suction disc 4422. The sixth driving member 4421 is arranged on the second ball screw 441. The first suction disc 4422 is arranged on the sixth driving member 4421. The sixth driving member 4421 is configured to drive the first suction disc 4422 to ascend or descend. Figure 11 In this embodiment, the sixth driving member 4421 is arranged on the second ball screw 441. The second ball screw 441 is configured to drive the sixth driving member 4421 to move. The first suction disc 4422 is arranged on the sixth driving member 4421. The sixth driving member 4421 is configured to drive the first suction disc 4422 to ascend or descend.

[0519] During the taking process, the sixth driving member 4421 can drive the first suction disc 4422 to descend, so as to facilitate the first suction disc 4422 to suction the front plate 910. When the sixth driving member 4421 moves above the first welding position, the sixth driving member 4421 can drive the first suction disc 4422 to descend. In this way, the first suction disc 4422 can stably place the front plate 910 on the second welding cavity 820, thereby improving the stability during the transferring process of the front plate 910.

[0520] For example, the sixth driving member 4421 can be a pneumatic cylinder. In other embodiments, the sixth driving member 4421 can also be a structure of a motor plus a gear set.

[0521] As shown in FIG. 14, in one possible embodiment, the second transferring assembly 440 includes a second ball screw 441 and a second suction assembly 442. The second ball screw 441 is arranged on the first rack 410. The second suction assembly 442 is arranged on the second ball screw 441. The second ball screw 441 is configured to drive the second suction assembly 442 to move. The second suction assembly 442 is configured to suction the front plate 910.

[0522] Figure 12 ​As shown, in a possible embodiment, the second transferring assembly 440 further comprises a third suction assembly 443, the third suction assembly 443 is arranged on the second ball screw 441, and the third suction assembly 443 is configured to suction the front plate 910 after welding, so as to drive the front plate 910 after welding and the second cavity to be welded 820 to move to a lower position.

[0523] In this embodiment, the third suction assembly 443 is arranged on the second ball screw 441, and the second ball screw 441 can drive the third suction assembly 443 to move.

[0524] When the second cavity to be welded 820 and the front plate 910 are welded, the third suction assembly 443 can suction the third cavity to be welded 830, and the third suction assembly 443 can drive the third cavity to be welded 830 to move to a next station.

[0525] The second ball screw 441 can drive the second suction assembly 442 and the third suction assembly 443 to move at the same time, the second suction assembly 442 suctions the front plate 910, and the third suction assembly 443 suctions the third cavity to be welded 830, so that the feeding process and the discharging process are synchronized. By using one ball screw to drive two suction assemblies to move, the structure of the front plate welding device 400 is effectively simplified.

[0526] As shown in the drawings, Figure 12 In a possible embodiment, the third suction assembly 443 comprises a seventh driving member 4431 and a second suction disc 4432, the seventh driving member 4431 is arranged on the second ball screw 441, and the second suction disc 4432 is arranged on the seventh driving member 4431, and the seventh driving member 4431 is configured to drive the second suction disc 4432 to ascend or descend.

[0527] In this embodiment, the seventh driving member 4431 is arranged on the second ball screw 441, and the second ball screw 441 can drive the seventh driving member 4431 to move. The second suction disc 4432 is arranged on the seventh driving member 4431, and the seventh driving member 4431 can drive the second suction disc 4432 to ascend or descend.

[0528] During the feeding process, the seventh driving member 4431 can drive the second suction disc 4432 to descend, so as to facilitate the second suction disc 4432 to stably suction the third cavity to be welded 830.

[0529] For example, the seventh driving member 4431 can be a pneumatic cylinder, and in other embodiments, the seventh driving member 4431 can also be a structure of a motor plus a gear set.

[0530] As shown in the drawings, Figure 13As shown, in a possible embodiment, the waveguide tube welding device 500 comprises a feeding table 510, a camera assembly 520, a second material taking assembly 530, a feeding assembly 540 and a second welding assembly 550. The feeding table 510 has a feeding position and is used to carry the waveguide tube 920 and drive the waveguide tube 920 to move to the feeding position. The camera assembly 520 is arranged on one side of the feeding table 510 and is used to detect the position of the waveguide tube 920 located on the feeding position. The second material taking assembly 530 is arranged on one side of the feeding table 510 and is used to pick up the waveguide tube 920 located on the feeding position according to the detection signal of the camera assembly 520. The feeding assembly 540 is arranged on one side of the feeding table 510, and the second material taking assembly 530 is used to place the waveguide tube 920 on the feeding position of the feeding assembly 540. The feeding assembly 540 is used to drive the waveguide tube 920 to move to the second welding position. The second welding assembly 550 is arranged on one side of the feeding assembly 540 and is used to weld the third to-be-welded cavity 830 and the waveguide tube 920.

[0531] The waveguide tube welding device 500 provided by the embodiment can drive the waveguide tube 920 placed on the feeding table 510 to the feeding position. The feeding table 510 serves as a driving component and can drive the waveguide tube 920 to move. The feeding position refers to a position on the feeding table 510 where the waveguide tube 920 can be picked up. When the waveguide tube 920 moves to the feeding position, the camera assembly 520 arranged on one side of the feeding table 510 can detect the position of the waveguide tube 920 located on the feeding position. According to the detection result of the camera assembly 520, the second material taking assembly 530 can identify the waveguide tube 920 located on the feeding position.

[0532] Specifically, when the plurality of waveguide tubes 920 are transferred to the feeding position by the feeding table 510, the waveguide tubes 920 can be placed in a disordered manner at the feeding position, for example, the length direction of a part of the waveguide tubes 920 can be parallel to the conveying direction of the feeding table 510, and the length direction of another part of the waveguide tubes 920 has an angle with the conveying direction of the feeding table 510, causing the placement manners of the plurality of waveguide tubes 920 to be different. The camera assembly 520 can identify the position of the waveguide tube 920 and determine the position and placement manner of the waveguide tube 920 at the feeding position. According to the detection result of the camera assembly 520, the second material taking assembly 530 can accurately pick up the waveguide tube 920, which is conducive to improving the stability when the waveguide tube 920 is transferred.

[0533] After the second material taking assembly 530 picks up the waveguide tube 920, the second material taking assembly 530 places the waveguide tube 920 on the feeding position of the feeding assembly 540. The feeding assembly 540 can drive the waveguide tube 920 to move to the second welding position.

[0534] The second welding assembly 550 is located on one side of the feeding assembly 540, and the second welding position is located on the second welding assembly 550. The second welding assembly 550 can weld the third to-be-welded cavity 830 and the waveguide tube 920.

[0535] Since the camera assembly 520 can identify the position of the waveguide tube 920, the second material taking assembly 530 adjusts the picking angle according to the identification result. Even if the positions and placements of different waveguide tubes 920 are different, the cooperation of the camera assembly 520 and the second material taking assembly 530 can ensure that the waveguide tube 920 is regularly placed at the material taking position, thereby achieving the function of positioning and feeding the waveguide tube 920. When the feeding assembly 540 moves the waveguide tube 920 to the welding position, the position of the waveguide tube 920 does not need to be adjusted by the worker, thereby ensuring that the waveguide tube 920 and the third to-be-welded cavity 830 can stably complete the welding process.

[0536] The feeding table 510, the second material taking assembly 530, and the feeding assembly 540 can automatically transfer the waveguide tube 920, thereby saving the workload of the worker for carrying the waveguide tube 920.

[0537] The cooperation of the camera assembly 520 and the second material taking assembly 530 can adjust the feeding position of the waveguide tube 920, so that the welding position of the waveguide tube 920 does not need to be adjusted by the worker, thereby further saving the workload of the worker.

[0538] In combination Figure 13 and Figure 14 As shown in FIG. 17, in a possible embodiment, the feeding assembly 540 includes a second guide rail assembly 541 and a fifth positioning assembly 542. The fifth positioning assembly 542 is arranged on the second guide rail assembly 541. The second guide rail assembly 541 is used to drive the fifth positioning assembly 542 to reciprocate between the material taking position and the second welding position. The fifth positioning assembly 542 is used to carry and position the waveguide tube 920.

[0539] In this embodiment, the second guide rail assembly 541 can drive the fifth positioning assembly 542 to move. The waveguide tube 920 can be placed on the fifth positioning assembly 542, so that the fifth positioning assembly 542 can drive the waveguide tube 920 to move.

[0540] The second material taking assembly 530 can place the waveguide tube 920 on the fifth positioning assembly 542. The fifth positioning assembly 542 can position the waveguide tube 920. During the movement of the waveguide tube 920 driven by the fifth positioning assembly 542, the waveguide tube 920 is not easy to move relative to the fifth positioning assembly 542, so that the fifth positioning assembly 542 can stably drive the waveguide tube 920 to move to the second welding position.

[0541] Under the cooperation of the camera assembly 520 and the second material taking assembly 530, the waveguide tube 920 can be accurately placed on the fifth positioning assembly 542. Under the positioning action of the fifth positioning assembly 542, the position of the waveguide tube 920 does not need to be adjusted by the staff, and the third to-be-welded part can be accurately and stably welded with the waveguide tube 920 by the second welding assembly 550, thereby the welding precision is improved.

[0542] In combination Figure 14 and Figure 13 As shown in FIGS. 11 and 12, in a possible embodiment, the fifth positioning assembly 542 comprises a bearing table 5421, a second positioning body 5422, a first driving source 5423 and a second driving source. The bearing table 5421 is arranged on the second guide rail assembly 541. The second positioning body 5422 is arranged on the bearing table 5421. The first driving source 5423 is arranged on the bearing table 5421, and is used for pushing the waveguide tube 920 towards the second positioning body 5422. The second driving source is arranged on the bearing table 5421, and is used for clamping the waveguide tube 920. The axial direction of the first driving source 5423 and the axial direction of the second driving source are perpendicular to each other.

[0543] In this embodiment, the bearing table 5421 is arranged on the second guide rail assembly 541, and the second guide rail assembly 541 can drive the bearing table 5421 to move. The bearing table 5421 serves as a bearing structure of the second positioning body 5422, the first driving source 5423 and the second driving source, so that the second positioning body 5422, the first driving source 5423 and the second driving source can be installed on the bearing table 5421, and the bearing table 5421 can drive the first driving source 5423 and the second driving source to move.

[0544] The second positioning body 5422 is fixed on the bearing table 5421, and the second positioning body 5422 is not easy to move relative to the bearing table 5421. When the waveguide tube 920 is placed between the first driving source 5423 and the second positioning body 5422, the first driving source 5423 can push the waveguide tube 920, so that the waveguide tube 920 is pushed towards the second positioning body 5422. The first driving source 5423 and the second positioning body 5422 clamp the waveguide tube 920, and the first level positioning of the waveguide tube 920 is realized. The second driving source can clamp the waveguide tube 920, and the second level positioning of the waveguide tube 920 is realized. In addition, the axial direction of the first driving source 5423 and the axial direction of the second driving source are perpendicular to each other, so the pushing directions of the first driving source 5423 and the second driving source to the waveguide tube 920 are different. For example, the waveguide tube 920 has four first side walls, second side walls, third side walls and fourth side walls connected respectively. The first driving source 5423 is used for pushing the first side wall, the second positioning body 5422 is in contact with the third side wall, and the second driving source pushes the second side wall and the fourth side wall.

[0545] The second driving source can clamp the waveguide tube 920, so that the second driving source can push the waveguide tube 920 to be centrally arranged. Under the positioning action of the first driving source 5423 and the second driving source, the waveguide tube 920 is pushed to the specified position, so that the waveguide tube 920 moved to the second welding position has been positioned, and the second welding assembly 550 can accurately weld the waveguide tube 920 and the third cavity to be welded 830. In addition, the first driving source 5423 and the second positioning body 5422 clamp the waveguide tube 920, and the second driving source clamps the waveguide tube 920, so that the waveguide tube 920 is not easy to be separated from the bearing table 5421, and the bearing table 5421 can stably drive the waveguide tube 920 to move.

[0546] In this embodiment, the first power source can be a cylinder.

[0547] As shown in Figure 12 In a possible embodiment, the second driving source includes a fourth cylinder, a fifth clamping plate 5426 and a sixth clamping plate 5427. The fourth cylinder is arranged on the bearing table 5421. The fifth clamping plate 5426 and the sixth clamping plate 5427 are arranged on the fourth cylinder, and the fourth cylinder is used to drive the fifth clamping plate 5426 and the sixth clamping plate 5427 to approach or move away from each other.

[0548] In this embodiment, the fourth cylinder is installed on the bearing table 5421, and the fifth clamping plate 5426 and the sixth clamping plate 5427 are installed on the output shaft of the fourth cylinder. The fourth cylinder can drive the fifth clamping plate 5426 and the sixth clamping plate 5427 to move, and the fifth clamping plate 5426 and the sixth clamping plate 5427 are located on the opposite sides of the waveguide tube 920.

[0549] When the waveguide tube 920 is placed on the bearing table 5421, the fourth cylinder acts, and the fourth cylinder drives the fifth clamping plate 5426 and the sixth clamping plate 5427 to approach each other, so that the fifth clamping plate 5426 and the sixth clamping plate 5427 push the waveguide tube 920. When the fifth clamping plate 5426 and the sixth clamping plate 5427 clamp the waveguide tube 920, the fifth clamping plate 5426 and the sixth clamping plate 5427 are centrally arranged, and the positioning of the waveguide tube 920 is realized. Moreover, under the clamping action of the fifth clamping plate 5426 and the sixth clamping plate 5427, the waveguide tube 920 is not easy to be separated from the bearing table 5421, and the bearing table 5421 can stably drive the waveguide tube 920 to move.

[0550] As shown in Figure 12As shown, in one possible embodiment, the second guide rail assembly 541 includes: a fifth ball screw 5411 and a sixth ball screw 5412, a fifth positioning component 542 is disposed on the fifth ball screw 5411, and the fifth ball screw 5411 is used to drive the fifth positioning component 542 to move in the horizontal direction; the fifth ball screw 5411 is disposed on the sixth ball screw 5412, and the sixth ball screw 5412 is used to drive the fifth ball screw 5411 to rise or fall.

[0551] In this embodiment, the fifth positioning component 542 is disposed on the fifth ball screw 5411, and the fifth ball screw 5411 extends axially in the horizontal direction, so that the fifth ball screw 5411 can drive the fifth positioning component 542 to move in the horizontal direction.

[0552] The fifth ball screw 5411 is mounted on the sixth ball screw 5412, and the sixth ball screw 5412 extends axially along the plumb line, allowing the sixth ball screw 5412 to drive the fifth ball screw 5411 to rise or fall. The fifth ball screw 5411 and the sixth ball screw 5412 work together to adjust the position of the fifth positioning assembly 542 in the horizontal and plumb directions.

[0553] Specifically, when the fifth positioning component 542 needs to pick up material, the fifth ball screw 5411 drives the fifth positioning component 542 to move to the picking position. During the picking process, the sixth ball screw 5412 can drive the fifth ball screw 5411 to rise or fall, thereby adjusting the height of the fifth positioning component 542 to be suitable for the second picking component 530 to place the waveguide 920, which helps to improve the coordination stability of the second picking component 530 and the second guide rail component 541. When the fifth ball screw 5411 drives the fifth positioning component 542 to move towards the second welding position, the sixth ball screw 5412 can drive the fifth ball screw 5411 to rise or fall, thereby adjusting the height of the fifth positioning component 542 so that the height of the fifth positioning component 542 is adjusted to be suitable for placing the waveguide 920 in the second welding component 550 for welding, which helps to improve the coordination stability of the second guide rail component 541 and the second welding component 550.

[0554] like Figure 12 As shown, in one possible embodiment, the camera assembly 520 includes: a frame 521, a mounting base 522, and at least one camera, wherein the mounting base 522 is disposed on the frame 521; and at least one camera is disposed on the mounting base 522, with the camera positioned above the feed table 510.

[0555] In this embodiment, the mounting seat 522 is arranged on the frame 521, and the camera is mounted on the mounting seat 522. The mounting seat 522 is detachably connected to the frame 521, so that the mounting seat 522 and the camera can be detached from the frame 521 together. When the mounting seat 522 or the camera is damaged, the mounting seat 522 and the camera can be detached from the frame 521, so that the mounting seat 522 and the camera can be maintained separately, which is beneficial to reduce the maintenance cost of the camera assembly 520.

[0556] The camera is located above the feeding table 510, so that the camera can obtain the picture on the feeding table 510. When the waveguide tube 920 moves to the feeding position, the camera can identify the position of the waveguide tube 920, determine the position and placement mode of the waveguide tube 920 at the feeding position, and the second material taking assembly 530 can accurately pick up the waveguide tube 920 according to the detection result of the camera, which is beneficial to improve the stability during transferring the waveguide tube 920.

[0557] For example, the camera can be a charge-coupled device camera, which has the advantages of small volume, light weight, no interference from magnetic field and anti-vibration, and can ensure the stability during obtaining the position of the waveguide tube 920. The charge-coupled device camera can convert the image into a digital signal, and then the digital signal can be transmitted to the second material taking assembly 530, so that the second material taking assembly 530 can accurately pick up the waveguide tube 920.

[0558] The number of cameras can be at least one. By increasing the number of cameras, the accuracy of detecting the position of the waveguide tube 920 can be improved.

[0559] As shown in Figure 12 In a possible embodiment, the camera assembly 520 further includes a first connecting hole, at least two second connecting holes 523, and a locking piece. The first connecting hole is arranged on the frame 521. The at least two second connecting holes 523 are arranged on the mounting seat 522. The locking piece passes through the first connecting hole and the second connecting holes 523 to lock the mounting seat 522 on the frame 521.

[0560] In this embodiment, the frame 521 is provided with a first connecting hole, and the mounting seat 522 is provided with at least two second connecting holes 523. The locking piece can pass through the first connecting hole and one of the second connecting holes 523 on the mounting seat 522, so that the locking piece can lock the mounting seat 522 on the frame 521.

[0561] The locking member can pass through any second connecting hole 523 on the mounting base 522, so that the mounting base 522 can be connected with the frame 521 at different positions, and the relative position of the mounting base 522 and the frame 521 can be adjusted. By adjusting the mounting position of the mounting base 522, the position of the camera relative to the loading position can be adjusted, so that the camera can be adjusted to a position suitable for obtaining an image at the loading position, and the accuracy of the image obtained by the camera can be improved.

[0562] Exemplarily, the locking member can be a bolt, and the first connecting hole can be a threaded hole. During installation, the bolt is first passed through the second connecting hole 523, and then the bolt is connected with the threaded hole, so that the mounting base 522 is locked to the frame 521.

[0563] As shown in Figure 12 In a possible embodiment, the feeding table 510 includes a support frame 511 and a belt assembly 512, the belt assembly 512 is arranged on the support frame 511, and the belt assembly 512 is used to drive the waveguide tube 920 to move.

[0564] In this embodiment, the belt assembly 512 is installed on the support frame 511, and the belt assembly 512 can drive the waveguide tube 920 to move, so that the belt assembly 512 can drive the waveguide tube 920 to move to the loading position. The operation process of the belt assembly 512 is relatively stable, so the belt assembly 512 can stably drive the waveguide tube 920 to move.

[0565] The belt assembly 512 includes a motor, a driving wheel, a driven wheel, and a belt, the belt is sleeved on the driving wheel and the driven wheel, and the motor drives the driving wheel to rotate, so that the driving wheel can drive the belt to rotate.

[0566] As shown in Figure 12 In a possible embodiment, the feeding table 510 further includes a first bus member 513 and a second bus member 514, the first bus member 513 and the second bus member 514 are arranged on the support frame 511, the first bus member 513 and the second bus member 514 are located on both sides of the belt assembly 512 along the width direction, and the distance between at least part of the first bus member 513 and the second bus member 514 decreases along the transmission direction of the belt assembly 512.

[0567] In this embodiment, the support frame 511 is provided with a first busbar 513 and a second busbar 514, at least part of the first busbar 513 and at least part of the second busbar 514 are above the belt assembly 512, and the first busbar 513 and the second busbar 514 are located on both sides of the belt assembly 512 in the transmission direction, so that the first busbar 513 and the second busbar 514 can limit the waveguide tube 920 conveyed on the belt assembly 512, avoid the waveguide tube 920 from falling, and improve the stability of the waveguide tube 920 moving with the belt assembly 512.

[0568] Along the transmission direction of the belt assembly 512, the distance between the first busbar 513 and the second busbar 514 decreases. The first busbar 513 and the second busbar 514 can play a role in converging, and as the distance between the first busbar 513 and the second busbar 514 decreases, the waveguide tube 920 is gradually pushed towards the middle of the belt assembly 512, so that the waveguide tube 920 is conveyed centrally on the belt assembly 512. When the waveguide tube 920 moves to the loading position, the waveguide tube 920 is concentrated below the camera, ensuring that the camera can accurately obtain the position of the waveguide tube 920.

[0569] For example, along the transmission direction of the belt assembly 512, the distance between the first busbar 513 and the second busbar 514 first decreases and then remains unchanged. The distance between the first busbar 513 and the second busbar 514 decreases to play a role in converging the waveguide tube 920, and the distance between the first busbar 513 and the second busbar 514 remains unchanged to avoid the accumulation of multiple waveguide tubes 920 due to the small distance between the first busbar 513 and the second busbar 514, which helps to improve the stability of the conveying process.

[0570] As shown in Figure 12 In a possible embodiment, the feeding table 510 further comprises a second sensor 515, the second sensor 515 is arranged on the support frame 511, and the second sensor 515 is located at the loading position and used to detect the position of the waveguide tube 920.

[0571] In this embodiment, the second sensor 515 is installed on the support frame 511, and the second sensor 515 is located at the loading position, so the second sensor 515 can detect whether there is a waveguide tube 920 at the loading position.

[0572] Specifically, the second sensor 515 can be linked with the belt assembly 512, and when the second sensor 515 detects a waveguide tube 920 at the loading position, the belt assembly 512 stops running, so that the waveguide tube 920 can stay at the loading position.

[0573] The second sensor 515 can be linked with the camera assembly 520. When the second sensor 515 detects the presence of the waveguide 920 at the loading position, the camera assembly 520 activates and detects the position of the waveguide 920. This method avoids prolonged operation of the camera assembly 520, thus extending its service life. Furthermore, by using the second sensor 515 to detect the presence of the waveguide 920 at the loading position, false detections by the camera assembly 520 can be avoided, thereby improving the operational stability of the waveguide welding device 500.

[0574] For example, the second sensor 515 may be an infrared sensor or a gravity sensor.

[0575] In one possible embodiment, the feeding table 510 further includes a baffle, which is disposed on the support frame 511 and located on one side of the feeding position. The baffle is used to restrict the waveguide 920 from disengaging from the belt assembly 512.

[0576] In this embodiment, a baffle is provided on the support frame 511. The baffle can block the waveguide 920 and prevent the waveguide 920 from falling.

[0577] The baffle serves a protective function. When the second sensor 515 malfunctions, the waveguide 920 may move to the loading position, but the belt assembly 512 may not stop running. By setting the baffle to block the waveguide 920, even if the belt assembly 512 does not stop running, the waveguide 920 is less likely to fall outside the belt assembly 512, thus reducing the damage rate of the waveguide 920.

[0578] like Figure 12 As shown, in one possible embodiment, the feeding table 510 further includes a first height adjustment component 516, which is disposed on the support frame 511 and is used to adjust the height of the support frame 511.

[0579] In this embodiment, the first height adjustment component 516 can adjust the height of the support frame 511, thereby indirectly adjusting the height of the belt assembly 512.

[0580] Specifically, by indirectly adjusting the height of the belt assembly 512 through the first height adjustment component 516, the belt assembly 512 can be adjusted to a height suitable for the second material taking component 530 to take material, thereby improving the coordination stability of the belt assembly 512 and the second material taking component 530.

[0581] Exemplarily, the bottom of the support frame 511 is provided with a threaded hole, the first height adjusting assembly 516 includes a base and a screw rod, the screw rod is connected with the threaded hole, by rotating the screw rod, the length of the screw rod extending into the threaded hole can be adjusted, and then the height of the support frame 511 can be adjusted. Of course, in other embodiments, the height of the support frame 511 can also be adjusted by the mutually sleeved pipe bodies.

[0582] As shown in Figure 15 In a possible embodiment, the second taking component 530 includes a mechanical arm 531 and a fixing frame 532, the mechanical arm 531 is used for picking up the waveguide tube 920 located at the feeding position, and the mechanical arm 531 is arranged on the fixing frame 532.

[0583] In this embodiment, when the camera assembly 520 acquires the position of the waveguide tube 920 at the feeding position, the mechanical arm 531 picks up the waveguide tube 920 located at the feeding position according to the detection result of the camera assembly 520. The mechanical arm 531 can be a multi-axis structure, so that the mechanical arm 531 can flexibly adjust the grabbing position, facilitate picking up the waveguide tube 920 located at different positions and different placement modes, and improve the stability of the waveguide tube 920 transfer process.

[0584] The fixing frame 532 supports the mechanical arm 531, and the mechanical arm 531 can be lifted through the fixing frame 532, so as to facilitate the mechanical arm 531 to pick up the waveguide tube 920. Compared with the way of increasing the overall height of the mechanical arm 531, the fixing frame 532 can reduce the processing cost.

[0585] As shown in Figure 16 In a possible embodiment, the second taking component 530 further includes a second height adjusting assembly 533, the second height adjusting assembly 533 is arranged on the fixing frame 532, and the second height adjusting assembly 533 is used for adjusting the height of the fixing frame 532.

[0586] In this embodiment, the second height adjusting assembly 533 can adjust the height of the fixing frame 532, so as to indirectly adjust the height of the mechanical arm 531.

[0587] Specifically, by indirectly adjusting the height of the mechanical arm 531 through the second height adjusting assembly 533, the mechanical arm 531 can be adjusted to a height suitable for picking up the waveguide tube 920, and the cooperation stability of the second height adjusting assembly 533 and the belt assembly 512 is improved.

[0588] Exemplarily, the bottom of the support frame 511 is provided with a threaded hole, the first height adjusting assembly 516 includes a base and a screw rod, the screw rod is connected with the threaded hole, by rotating the screw rod, the length of the screw rod extending into the threaded hole can be adjusted, and then the height of the support frame 511 can be adjusted. Of course, in other embodiments, the height of the support frame 511 can also be adjusted by the mutually sleeved pipe bodies.

[0589] In combination Figure 15 and Figure 19 As shown in FIG. 7, in one possible implementation, the rear plate welding device 700 includes a second rack 710, a third transfer assembly 720, a fourth transfer assembly 730, a positioning reference part, a third positioning assembly 750, a fourth positioning assembly 760, and a third welding assembly 770. The third transfer assembly 720 is arranged on the second rack 710 and is configured to drive the fourth to-be-welded cavity 840 to move to a third welding position. The fourth transfer assembly 730 is arranged on the second rack 710 and is configured to drive the rear plate 930 to move to the third welding position. The positioning reference part 740 is arranged on the second rack 710, and the fourth to-be-welded cavity 840 abuts against the positioning reference part 740 when the fourth to-be-welded cavity 840 moves to the third welding position. The third positioning assembly 750 is arranged on the transfer assembly and is configured to position the fourth to-be-welded cavity 840. The fourth positioning assembly 760 is arranged on the second rack 710 and is located at the third welding position. The fourth positioning assembly 760 is configured to position the rear plate 930. The third welding assembly 770 is arranged on the second rack 710 and is configured to weld the fourth to-be-welded cavity 840 and the rear plate 930.

[0590] The rear plate welding device 700 provided in this embodiment can drive the fourth to-be-welded cavity 840 to move by means of the third transfer assembly 720. The third positioning assembly 750 is arranged on the third transfer assembly 720, and the third positioning assembly 750 can position the fourth to-be-welded cavity 840. Under the positioning action of the third positioning assembly 750, the fourth to-be-welded cavity 840 is less likely to move relative to the third transfer assembly 720, so that the third positioning assembly 750 can stably drive the fourth to-be-welded cavity 840 to move to the third welding position.

[0591] The fourth to-be-welded cavity 840 can have a three-dimensional structure with four side edges and a front plate 910, and needs to be welded with the rear plate 930.

[0592] When the fourth to-be-welded cavity 840 and the back plate 930 need to be welded, the third transfer assembly 720 drives the fourth to-be-welded cavity 840 to move to the first welding position, and the third positioning assembly 750 can position the fourth to-be-welded cavity 840 during the movement. When the fourth to-be-welded cavity 840 moves to the first welding position, the positioning reference part 740 abuts against the fourth to-be-welded cavity 840, and the positioning reference part 740 limits the continuous movement of the fourth to-be-welded cavity 840, so as to position the fourth to-be-welded cavity 840 to the third welding position. During the movement, the fourth to-be-welded cavity 840 is not easy to move relative to the third transfer assembly 720. When the fourth to-be-welded cavity 840 is in contact with the positioning reference part 740, it indicates that the fourth to-be-welded cavity 840 has been accurately moved to the third welding position. Through the cooperation of the third positioning assembly 750 and the positioning reference part 740, the stability and accuracy of the welding process are facilitated.

[0593] The fourth transfer assembly 730 can drive the back plate 930 to move to the third welding position, so that the back plate 930 can be automatically transferred to the third welding position. The third welding assembly 770 near the third welding position can weld the back plate 930 and the fourth to-be-welded cavity 840, and automatically complete the welding process.

[0594] The fourth positioning assembly 760 is arranged at the third welding position, and can position the front plate 910 moved to the third welding position, so that the back plate 930 is accurately positioned to the position to be welded. Moreover, under the positioning action of the fourth positioning assembly 760, the front plate 910 is not easy to shake, so that the back plate 930 and the fourth to-be-welded cavity 840 can stably complete the welding process.

[0595] Through the third transfer assembly 720 driving the fourth to-be-welded cavity 840 to move, and the fourth transfer assembly 730 driving the back plate 930 to move, the transfer of the fourth to-be-welded cavity 840 and the back plate 930 is automatically completed, and the workload of the staff for carrying the fourth to-be-welded cavity 840 and the back plate 930 is saved.

[0596] Through the third positioning assembly 750 and the positioning reference part 740 positioning the fourth to-be-welded cavity 840, and the fourth positioning assembly 760 positioning the back plate 930, the positioning of the fourth to-be-welded cavity 840 and the back plate 930 is automatically realized, the workload of the staff for positioning the fourth to-be-welded cavity 840 and the back plate 930 is saved, and compared with the manual positioning mode, the positioning mode of the mechanical structure can improve the positioning accuracy. The fourth to-be-welded cavity 840 and the back plate 930 can be accurately welded by the welding assembly, so as to avoid the occurrence of poor welding, and facilitate to improve the processing precision of the cooking cavity.

[0597] In combination with Figure 19 andFigure 20 As shown in the possible embodiment, the rear plate 930 comprises: a first side edge, a second side edge, a third side edge and a fourth side edge connected in sequence; the fourth positioning assembly 760 comprises: a first positioning member 761, a second positioning member 762, a third positioning member 763 and a fourth positioning member 764, the first positioning member 761 is arranged on the second rack 710 and is used for pushing the first side edge and the second side edge; the second positioning member 762 is arranged on the second rack 710 and is used for pushing the second side edge and the third side edge; the third positioning member 763 is arranged on the second rack 710 and is used for pushing the third side edge and the fourth side edge; and the fourth positioning member 764 is arranged on the second rack 710 and is used for pushing the third side edge and the fourth side edge.

[0603] In this embodiment, the first driving part 7611 is a cylinder, and in other embodiments, the first driving part 7611 can also be a combination structure of a motor and a gear.

[0604] The second positioning member 762 includes a second driving part, a third pushing plate and a fourth pushing plate, and the second driving part is arranged on the second rack 710. The third pushing plate is connected to the fourth pushing plate, and the third pushing plate and / or the fourth pushing plate are arranged on the second driving part. The third pushing plate is used to push the second side, and the fourth pushing plate is used to push the third side.

[0605] The third positioning member 763 includes a third driving part, a fifth pushing plate and a sixth pushing plate, and the third driving part is arranged on the second rack 710. The fifth pushing plate is connected to the sixth pushing plate, and the fifth pushing plate and / or the sixth pushing plate are arranged on the third driving part.

The seventh pushing plate is used to push the fourth side, and the eighth pushing plate is used to push the first side.

[0607] During the positioning of the back plate 930, the four positioning members can act at the same time. For example, the first driving part 7611 drives the first pushing plate 7612 and the second pushing plate 7613 to move, the first pushing plate 7612 contacts the first side, the third driving part drives the fifth pushing plate and the sixth pushing plate to move, the fifth pushing plate contacts and pushes the third side, and after the pushing of the fifth pushing plate, the second side contacts the second pushing plate 7613, thereby realizing the positioning of the second side, and the other sides are the same.

[0608] In this embodiment, the second driving part, the third driving part and the fourth driving part are cylinders, and in other embodiments, they can also be combination structures of motors and gears.

[0609] In one possible application, the included angle between the first pushing plate 7612 and the second pushing plate 7613 is 90°.

[0610] As Figure 19As shown, in one possible embodiment, the positioning reference part 740 includes: a fifth driving part 741 and a first positioning plate 742. The first positioning plate 742 is disposed on the fifth driving part 741. The fifth driving part 741 is used to drive the first positioning plate 742 to move toward or away from the fourth cavity to be welded 840.

[0611] In this embodiment, the first positioning plate 742 serves as a reference for positioning the fourth cavity to be welded 840. When the third transfer component 720 moves the fourth cavity to be welded 840 to contact the first positioning plate 742, it indicates that the fourth cavity to be welded 840 has moved into place.

[0612] The fifth drive unit 741 can push the first positioning plate 742 to move, allowing the first positioning plate 742 to approach or move away from the fourth cavity to be welded 840. Specifically, the first positioning plate 742 serves as a reference part. When the fourth cavity to be welded 840 contacts the first positioning plate 742, misalignment between the rear plate 930 and the fourth cavity to be welded 840 may occur. In this case, the fifth drive unit 741 needs to drive the second positioning plate to move, thereby adjusting the position of the second positioning plate, which helps to improve the positioning accuracy of the fourth cavity to be welded 840.

[0613] Furthermore, after welding the fourth cavity 840 to the rear plate 930, a fifth cavity is obtained, which needs to be transferred to the next workstation for processing. When the fifth cavity needs to be transferred, the fifth drive unit 741 can drive the first positioning plate 742 away from the fifth cavity to avoid interfering with the transfer process of the fifth cavity.

[0614] In this embodiment, the fifth drive unit 741 is a cylinder. In other embodiments, the fifth drive unit 741 may also be a combination structure of a motor and gears.

[0615] like Figure 15 As shown, in one possible embodiment, the positioning reference part 740 further includes: a sixth driving part 743 and a second positioning plate. The second positioning plate is disposed on the sixth driving part 743. When the rear plate 930 is in the third welding position, the second positioning plate is in contact with the side wall of the rear plate 930. The sixth driving part 743 is used to drive the second positioning plate toward or away from the rear plate 930.

[0616] In this embodiment, when the rear plate 930 is placed above the fourth welding cavity 840, there may be a significant deviation between the rear plate 930 and the welding position. In this case, the fourth positioning component 760 may be unable to adjust the position of the rear plate 930. The sixth driving unit 743 can push the second positioning plate, causing the second positioning plate to push the rear plate 930. The second positioning plate can push the rear plate 930 into a range that can be adjusted by the fourth positioning component 760, which helps to improve the stability of the welding process.

[0617] After welding is completed, the sixth drive unit 743 drives the second positioning plate away from the rear plate 930 to avoid interfering with the transfer process of the fifth cavity to be welded.

[0618] In this embodiment, the sixth drive unit 743 is a cylinder. In other embodiments, the sixth drive unit 743 may also be a combination structure of a motor and gears.

[0619] like Figure 16 As shown, in one possible embodiment, the positioning reference unit 740 further includes a seventh drive unit 745, which is disposed on the second frame 710. The fifth drive unit 741 and the sixth drive unit 743 are disposed on the seventh drive unit 745. The seventh drive unit 745 is used to drive the fifth drive unit 741 and the sixth drive unit 743 to rise or fall, so that the positioning reference unit 740 can avoid the fourth cavity to be welded 840 and the back plate 930 after welding.

[0620] In this embodiment, the fifth drive unit 741 and the sixth drive unit 743 are disposed on the seventh drive unit 745, and the seventh drive unit 745 can drive the fifth drive unit 741 and the sixth drive unit 743 to rise or fall.

[0621] After the fourth welding cavity 840 is welded to the rear plate 930, the fifth welding cavity needs to be transferred to the next station. At this time, the seventh drive unit 745 can drive the fifth drive unit 741 and the sixth drive unit 743 to descend, avoiding interference between the fifth drive unit 741 and the sixth drive unit 743 and the fifth welding cavity, thus ensuring the operational stability of the rear plate welding device 700. After the fifth welding cavity is removed, the seventh drive unit 745 drives the fifth drive unit 741 and the sixth drive unit 743 to rise, allowing the fifth drive unit 741 and the sixth drive unit 743 to continue positioning the next welding cavity, the rear plate 930, and the fourth welding cavity 840.

[0622] In this embodiment, the seventh drive unit 745 is a cylinder. In other embodiments, the seventh drive unit 745 may also be a combination structure of a motor and gears.

[0624] In this embodiment, when the fourth to-be-welded cavity 840 is placed on the third transferring assembly 720, the eighth driving part 752 drives the second supporting rib 751 to move so that the second supporting rib 751 is in contact with the plurality of inner walls of the fourth to-be-welded cavity 840.

[0625] The fourth to-be-welded cavity 840 has four side walls, and the eighth driving part 752 can drive the second supporting rib 751 to be in contact with the four side walls of the fourth to-be-welded cavity 840, and the second supporting rib 751 supports the inner walls of the fourth to-be-welded cavity 840, thereby fixing the fourth to-be-welded cavity 840 on the third transferring assembly 720.

[0626] Since the second supporting rib 751 can be in contact with the plurality of side walls of the fourth to-be-welded cavity 840, the second supporting rib 751 can push the plurality of side walls of the fourth to-be-welded cavity 840, thereby adjusting the position of the fourth to-be-welded cavity 840 on the third transferring assembly 720, and achieving the function of positioning the fourth to-be-welded cavity 840, and when the third transferring assembly 720 moves the fourth to-be-welded cavity 840 to the third welding position, the position of the fourth to-be-welded cavity 840 does not need to be adjusted, which is beneficial to realize the precise welding of the fourth to-be-welded cavity 840 and the front plate 910.

[0627] The second supporting rib 751 supports the fourth to-be-welded cavity 840, so that the fourth to-be-welded cavity 840 is not easy to shake relative to the third transferring assembly 720, which is beneficial to improve the stability when the fourth to-be-welded cavity 840 is transferred.

[0630] The first sub-driving member and the second sub-driving member can be arranged to be perpendicular to each other in the axial direction. For example, the first sub-driving member drives the fifth support part 7511 to push the first inner wall, and as the first inner wall is pushed, the third inner wall will be in contact with the seventh support part 7513. The second sub-driving member drives the eighth support part 7514 to push the fourth inner wall, and as the fourth inner wall is pushed, the second inner wall will be in contact with the first support plate 1424.
