Description

Technical Field

[0001] The present invention relates to the technical field of electric box manufacturing, and particularly to an intelligent welding tooling for an electric box body and a using method thereof. Background Technique

[0002] An electric box, also known as a distribution box or a power distribution cabinet, is to assemble switch devices, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements to form a low-voltage power distribution device. It is used to reasonably distribute electric energy, facilitate the opening and closing operation of the circuit, and has a high safety protection level, and can intuitively display the conduction state of the circuit.

[0003] The electric box body is generally welded by multiple sheet metal plates according to certain dimensions. This structure is simple, and is welded after cutting, bending and punching. Before welding, preparatory work needs to be carried out, including checking the drawings and technical requirements, checking whether the grounding of the electric welding machine is good, removing the dirt on both sides of the welding edge, etc. When welding, flat welding should be used as much as possible. If other positions are used for welding, the welding current should be adjusted to be 10% less than the flat welding current. During the welding process, the dimensions should be measured at any time to prevent the distribution box from deforming. When the weld is long or the structure is assembled, it should be spot welded in segments first and then welded to avoid deformation. After welding the distribution box, the slag skin should be knocked off, and the welding beads and welding slag should be cleaned to ensure that the weld is smooth and clean.

[0004] Because the welding of the electric box body is generally right-angle welding, during the welding process, the plate body needs to be fixed and clamped to avoid displacement and deformation. At the same time, the dimensions need to be checked during the welding process. Generally, experienced workers are required to support or use an external clamping structure for local fixation. The former lacks accuracy, while the latter lacks a certain degree of flexibility. Summary of the Invention

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-13 , the present invention provides a technical solution: an intelligent welding tooling for an electric box body, including a welding mechanism and a clamping mechanism. The clamping mechanism includes a rotating device 1, a turntable 2, a fixed seat 3 and a splicing component. Among them, the rotating device 1 is fixed under the welding mechanism, the turntable 2 is installed at the driving end of the rotating device 1, the fixed seat 3 is installed on the turntable 2, and a first plate 4 and a second plate 5 are placed. The splicing component is arranged on one side of the fixed seat 3. The fixed seat 3 is used to assist the splicing component to splice the first plate 4 and the second plate 5 into a right angle state for the welding mechanism to weld.

[0037] The splicing component includes a moving frame 60. A plurality of pressure sensing cavities 601 are provided on the lower side of the moving frame 60. One end of a first spring 602 is connected to the inner wall of each pressure sensing cavity 601, and the other end of the first spring 602 is connected to a telescopic frame 603. A plurality of pressure sensing chambers 604 are provided on the outer side of the telescopic frame 603. An active block 605 is respectively arranged in each pressure sensing chamber 604. Elastic ropes 606 are connected between both sides of the active block 605 and the pressure sensing chamber 604. A friction part 607 is arranged on the outer side of the active block 605.

[0038] Based on the above structure, the following supplementary description is as follows: In the initial state, the telescopic frame 603 extends out of the surface of the moving frame 60 under the action of the first spring 602. The active block 605 is suspended in the middle position of the pressure sensing chamber 604 under the constraint of the elastic ropes 606 on both sides. The pressure sensing cavity 601 is used to detect the force state of the telescopic frame 603, and the pressure sensing chamber 604 is used to detect the position of the active block 605.

[0039] Further, as Figure 4 shown, an adsorption chamber 608 is arranged on the moving frame 60 in cooperation with each pressure sensing cavity 601. A first soft pad 609 is arranged on the outer side of the adsorption chamber 608, a switching valve 610 is arranged on the other side of the adsorption chamber 608, the adsorption chamber 608 is connected to an air chamber 611, and an air pump 612 is externally connected to the air chamber 611.

[0040] It should be added that: a filter layer 613 is arranged in the air chamber 611 to filter impurities in the flowing air. The rotating device 1 is preferably a positioner.

[0041] In actual operation, when the adsorption chamber 608 approaches the surface of the second plate member 5, the first air pump 612 starts to pump air, and a negative pressure state is formed inside the adsorption chamber 608, causing the corresponding first soft pad 609 to adsorb on the surface of the second plate member 5, playing a role in positioning and fixing.

[0042] As Figures 5-7 shown, a first screw drive module 614 is provided on the moving frame 60. A screw 615 is rotatably provided at the moving end of the first screw drive module 614. A moving block 616 is in threaded engagement with the screw 615. A first motor 617 is installed on the moving block 616 facing the fixed seat 3. The driving end of the first motor 617 is connected to a second soft pad 618. A second air pump 619 is fixed under the moving block 616. A vision module is provided on one side of the moving block 616 for assisting in movement. An air flow channel is provided in the second soft pad 618 and is connected to the second air pump 619.

[0043] Furthermore, a driving gear 620 is sleeved on one end of the screw 615. The driving gear 620 is in mating connection with a driving gear 621. The driving gear 621 is connected to a second motor 622.

[0044] Even further, a second screw drive module 623 is provided at the bottom of the moving frame 60.

[0045] In actual operation, the second motor 622 drives the screw 615 to rotate through the driving gear 621 and the driving gear 620, thereby driving the lateral movement of the moving block 616. The first screw drive module 614 and the second screw drive module 623 adopt, but are not limited to, the combination of a screw and a motor. Among them, the first screw drive module 614 is used to control the lateral movement of the moving block 616, and the second screw drive module 623 is used to control the distance between the moving frame 60 and the fixed seat 3.

[0046] In one embodiment, as Figures 8-9 shown, a fixing groove 30 is provided on one side of the fixed seat 3 for placing the first plate member 4. A clamping plate 31 is provided in the fixing groove 30. The clamping plate 31 is connected to an electric push rod 32. A pressure sensing module is laid at the bottom of the fixing groove 30 and is connected to several telescopic rods 33. A second spring 34 is provided in the telescopic rod 33. The other end of the telescopic rod 33 is connected to a push plate 35.

[0047] The push plate 35 can be multi-section and is correspondingly connected to each telescopic rod 33.

[0048] One side of the fixed seat 3 facing the splicing component is used to place the second plate member 5. A cooling component is provided at the splicing position of the fixed seat 3 relative to the first plate member 4 and the second plate member 5.

[0049] As Figure 10As shown in the figure, the cooling assembly includes a rotating cylinder 70, a third motor 71, a pumping device 72 and a refrigeration box 73. The rotating cylinder 70 is rotatably arranged in the fixed seat 3. The driving end of the third motor 71 is connected to the rotating cylinder 70 to drive its rotation. The refrigeration box 73 is fixed in the fixed seat 3 to manufacture cooling gas. The pumping device 72 is respectively connected to the rotating cylinder 70 and the refrigeration box 73 to transport the cooling gas in the refrigeration box 73 into the rotating cylinder 70.

[0050] Furthermore, the rotating cylinder 70 is of a hollow structure and is internally provided with a rotating shaft 701 and a partition 702. The partition 702 connects the rotating shaft 701 and the inner wall of the rotating cylinder 70 and divides the internal space of the rotating cylinder 70 into two parts. The rotating cylinder 70 is provided with several first windows 703 with respect to one of the spaces, and the rotating cylinder 70 is provided with several second windows 704 with respect to the other space. The fixed seat 3 is provided with air ports 36 in cooperation with the first windows 703 and the second windows 704, and a heat sensing module 37 is arranged between the air ports 36 to detect the temperature change during the welding process.

[0051] It should be added that: a cover plate 74 is arranged at the upper opening of the rotating cylinder 70. The cover plate 74 is fixed on the fixed seat 3. The third motor 71 is fixed on the cover plate 74 and its driving end passes through the cover plate 74 and is connected to the rotating shaft 701. The cover plate 74 is provided with a through hole connected to the pumping device 72. The pumping device 72 may be, but is not limited to, an air pump;

[0052] As Figures 11-12 shown, the first window 703 is of an annular structure. When the first window 703 corresponds to the air port 36, the air flow in the rotating cylinder 70 sprays cooling air flow annularly around. The second window 704 is of a circular structure and its area is smaller than that of the air port 36. When the second window 704 corresponds to the air port 36, the air flow in the rotating cylinder 70 concentrates at the center position and sprays cooling air flow.

[0053] As Figure 13 shown, the welding mechanism includes an x-axis movement module 81, a y-axis movement module 82 and a welding robot arm 83. The x-axis movement module 81 is arranged on both sides of the clamping mechanism. The y-axis movement module 82 is fixed on the moving end of the x-axis movement module 81. The welding robot arm 83 is arranged on the moving end of the y-axis movement module 82.

[0054] In actual operation, the x-axis moving module 81 and the y-axis moving module 82 are used to adjust the position of the welding robot arm 83. In one embodiment, the x-axis moving module 81 includes a set of slide rails 811, a gantry 812, a motor 813 and a rack 814. The gantry 812 is slidably matched with the slide rails 811. The motor 813 is respectively fixed on one side of the gantry 812 and a gear is provided on the driving end. The rack 814 is respectively arranged on the slide rails 811 and matched with the gear teeth on the motor 813. When the motor is started, the gear will be driven to drive the gantry 812 to move along the direction of the rack 814; the y-axis moving module 82 adopts but is not limited to the screw motor matching method; the welding robot arm 83 can autonomously adjust the welding port and locate the welding position.

[0055] The specific welding methods are as follows:

[0056] First, fix the plate 14. Place the plate 14 into the fixing groove 30 manually or by an externally set mechanical arm with the welding end facing outward. According to the thickness of the plate 14, the electric push rod 32 pushes the clamp 31 to one side of the plate 14 to locally limit the position but does not restrict the movement of the plate 14. The moving frame 60 moves to the front side of the plate 14, and the moving block 616 is adjusted to the position of the plate 14. The moving frame 60 continues to move forward. The soft pad 2 618 pushes the plate 14 into the fixing groove 30 to the splicing position. The plate 14 squeezes the push plate 35. The pressure sensing module at the bottom of the fixing groove 30 determines whether the plate 14 is in the correct position according to the detected pressure distribution state. If it is not in the correct position, it is adjusted. After the adjustment is completed, the clamp 31 clamps the plate 14 and the soft pad 2 618 is separated from the surface of the plate 14.

[0057] Specifically, the pressure sensing module detects the pressure from the telescopic rods 33 at different positions. When the plate 14 is in the correct position, a certain number of telescopic rods 33 from bottom to top receive the same thrust from the plate 14, and the number of them is related to the height of the plate 14. If one end of the plate 14 is tilted, the telescopic rods 33 will receive uneven thrust. The pressure information corresponding to each telescopic rod 33 is collected, and the difference between adjacent signals is taken and compared with the set ideal value to determine whether it is within the ideal range. If so, the plate 14 is judged to be in the correct position, otherwise the plate 1 is placed unevenly and needs to be adjusted.

[0058] Furthermore, during adjustment, the cushion 2 618 is separated from the surface of the plate 1 4, and the clamping plate 31 is away from one end of the surface of the plate 1 4 to eliminate the influence of the limit being too tight. The cushion 2 618 pushes the plate 1 4 forward again and pulls it back, and this process is repeated until the plate 1 4 is adjusted to the correct position.

[0059] After the plate 1 4 is fixed, the plate 2 5 is adjusted and limited. The plate 2 5 is placed on one side of the fixed seat 3 manually or by an externally set mechanical arm, the moving frame 60 approaches the plate 2 5, the telescopic frame 603 is squeezed and contracted by the plate 2 5, the pressure sensing chamber 601 determines the specific position of the plate 2 5 according to the detected pressure quantity and position, and the pressure sensing chamber 604 determines whether the plate 2 5 is in the correct position according to the detected position of the movable block 605.

[0060] Specifically, the plate 2 5 pushes the telescopic frame 603 to make the pressure sensing chamber 601 detect the pressure. According to the pressure sensing chamber 601 that detects the pressure signal, the placement position of the plate 2 5 can be determined. The contraction degree of the telescopic frame 603 is related to the pressure. In the process of determining and adjusting the position of the plate 2 5, the moving block 616 moves to the middle of the plate 2 5, and the soft cushion 2 618 is used to provide support for the upper side of the plate 2 5 to prevent the plate 2 5 from tipping over. At the same time, the moving frame 60 controls the telescopic frame 603 to contract to half, and determines whether the plate 2 5 is in the correct position according to the pressure sensing chamber 604 corresponding to the pressure sensing chamber 601 that detects the pressure signal.

[0061] Furthermore, because the telescopic frame 603 is not fully retracted, the plate 25 is in an incompletely compressed state. Generally, when the plate 25 leans against one side of the fixed seat 3, it will be tilted at a certain angle. During the contraction of the telescopic frame 603, the plate 25 gradually stands upright, and the position of the plate 25 to which each movable block 605 is attached moves up, driving the corresponding movable block 605 to move up synchronously.

[0062] If the surface of the plate 2 5 is uneven and the local concave position cannot fit the movable block 605, the movable block 605 cannot move synchronously, and the position of the pressure signal detected by the pressure sensing chamber 604 corresponds to the position of each movable block 605. When the surface of the plate 2 5 is flat, the movable blocks 605 should be continuous and at the same height. When the height of the local movable blocks 605 is inconsistent, the flatness of the surface of the plate 2 5 should be checked.

[0063] Furthermore, if one side of the plate 2 5 is lifted during the limiting process, making the splicing side uneven, the corresponding movable block 605 should move up to a higher height than the other movable blocks 605. At this time, the moving frame 60 retreats and limits the position again. When it is determined that the surface quality of the plate 2 5 meets the standard and is in the correct position, the air pump 2 619 starts to pump air, and the soft cushion 2 618 is adsorbed on the surface of the plate 2 5. The plate 2 5 is moved to the splicing position according to the position of the plate 1 4. After the splicing position is aligned, the moving frame 60 continues to move forward to make the telescopic frame 603 completely retracted. At the same time, the air pump 1 612 pumps air, and the switch valve 610 corresponding to the retracted telescopic frame 603 opens, so that the soft cushion 1 609 is adsorbed on the lower surface of the plate 2 5 to achieve upper and lower limiting.

[0064] After being ready, the welding robotic arm 83 positions the welding location for welding. During the welding process, the thermal sensing module 37 determines whether to directly cool the concentrated welding points or indirectly cool the area around the welding points according to the heat distribution state. If the temperature of the welding point abnormally rises, the second window 704 is adjusted to correspond to the air port 36, and at the same time, a cooling air flow is input to directly spray the welding point; if the temperature of the welding point is on the high side, the first window 703 is adjusted to correspond to the air port 36, and at the same time, a cooling air flow is input to spray the cooling air flow around the welding point, and the welding point is indirectly cooled by means of heat exchange; if the temperature of the welding point is normal, no cooling is required. The judgment boundary is set manually.
