Description

Technical Field

[0001] The invention belongs to the technical field of welding, in particular to a thermal protector shell welding device. Background Art

[0002] A thermal protector is a device used to protect electrical equipment or circuits from damage due to overheating. It mainly works based on the response of thermal sensitive components to temperature. When the temperature in an electrical device or circuit rises to a certain level, the physical properties of the thermal sensitive components (such as resistance, shape, etc.) will change. This change will trigger the action mechanism of the thermal protector, thereby cutting off the circuit or taking other protective measures to prevent the equipment from being damaged due to overheating and avoid safety accidents such as fire. The shell of the thermal protector refers to the external structure that wraps and protects the core components inside the thermal protector.

[0003] Thermal protector shell welding equipment refers to professional equipment used to connect the various parts of the thermal protector shell together to form a complete, sealed shell with a certain strength through welding process.

[0004] A patent application with publication number CN117020538A discloses a welding fixture for electronic component packaging metal shell, including a design in which a fixed tube, a driving mechanism and a clamping mechanism cooperate with each other. Only through a first driving part, not only can the first clamping member and the second clamping member be driven to clamp and fix the electronic component packaging metal shell, but the position of the electronic component packaging metal shell can also be adjusted with the fixed tube as the axis. The fixture has the characteristics of easy adjustment, good flexibility and convenient welding.

[0005] In the current prior art, when the thermal protector housing and the metal spring are welded, since the metal spring has a certain plasticity, there will be a certain gap between the two when it is aligned with the thermal protector housing. Therefore, when the two are welded, since the metal spring cannot fit well with the thermal protector housing, a large weld or weld scar will be generated between the two, which affects the welding quality and the aesthetics of the welding.

[0006] To this end, the present invention provides a thermal protector shell welding device. Summary of the invention

[0009] By placing the thermal protector shell in the shell box, the solid shell component in the shell box fixes it to prevent the protector shell from shaking when the metal shrapnel and the protector shell are welded, which affects the welding effect. Then the intermittent conveyor belt drives the shell box to move. When the shell box moves into the working chamber, the docking component drives the metal shrapnel and the protector shell to align and contact. When the aligning and contacting of the two are completed, the welding mechanism welds the metal shrapnel and the protector shell. At the same time of welding, the straightening assembly drives the pressing plate to flatten the metal shrapnel to prevent the metal shrapnel and the thermal protector shell from not fully contacting. There is a gap between the two, which affects the welding effect and the aesthetics after welding. It is more conducive to the welding operation between the metal shrapnel and the protector shell, and plays a role in making the metal shrapnel and the protector shell fully contact. When the welding of the two is completed, the intermittent conveyor belt drives the shell box to move from the working chamber, drives the next shell box to move into the working chamber, and performs welding between the next metal shrapnel and the protector shell, realizing automatic welding between the two, repeating over and over again, which can speed up the efficiency during production and facilitate production.

During operation, the specifications and dimensions of the thermal protector shell in the shell box are identified by the identification component in the feeding device, and then the feeding component is driven to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device. When the metal shrapnel is thrown out, the metal shrapnel is driven to move to the specified position in the working chamber by controlling the batching robot arm, thereby playing the role of moving and assembling the metal shrapnel.

[0011] Preferably, a gantry is fixedly installed on the top of the intermittent conveyor belt, and a plurality of detection heads are fixedly installed on the inner wall of the gantry. During operation, when the intermittent conveyor belt drives the shell box to move, the detection head at the bottom of the gantry detects the outer shell of the thermal protector placed in the shell box.

The identification component in the feeding device will control the feeding component to throw out the metal shrapnel that is compatible with the outer shell of the thermal protector in the shell box according to the message transmitted back by the detection head, thereby playing a detection role.

[0012] Preferably, a telescopic cylinder is symmetrically fixedly installed on the inner wall of the working chamber, and a sheet placing plate is symmetrically slidably connected to the inner wall of the working chamber. The output ends of the two telescopic cylinders are respectively fixedly connected to the outer walls of the two sheet placing plates. The setting height of the two sheet placing plates is consistent with the inner wall height of the material placing trough plate. When the batching robot arm drives the metal spring sheet into the working chamber, the batching robot arm drives the metal spring sheet to move to the center position between the two sheet placing plates, thereby placing the metal spring sheet. When the docking assembly drives it to align and contact with the thermal protector shell, the telescopic cylinder drives the two sheet placing plates to open to both sides to provide a path for the docking of the two. When the welding mechanism completes the welding of the metal spring sheet and the protector shell, the docking assembly is reset, and the telescopic cylinder will drive the two sheet placing plates to move and reset again to form a complete placing plate, thereby providing a placement point for the placement of the next metal spring sheet, thereby playing the role of placing the metal spring sheet.

[0013] Preferably, the solid shell assembly includes a solid shell block, and there are multiple solid shell blocks. The outer walls of the multiple solid shell blocks are slidably connected to the inner wall of the shell box, and a push block spring is arranged between one side of the multiple solid shell blocks and the inner wall of the shell box. The tops of the multiple solid shell blocks are all inclined sliding surfaces, and the protector shell is fixed between the multiple solid shell blocks. Before work, the protector shell is pressed and placed in the shell box. When the protector shell moves in the shell box, the outer wall of the protector shell will squeeze the multiple solid shell blocks in the shell box to move. When the protector shell moves and contacts the inner wall of the shell box, the shell box is stopped, and the multiple solid shell blocks in the shell box will be pushed by the elastic push of the push block spring. The entering protector shell is fixed in place, which plays the role of fixing the protector shell. The protector shell is fixed in place by moving multiple solid shell blocks. The identification component in the feeding device detects and identifies the specifications of the thermal protector shell in the shell box through the detection head, and then drives the feeding component to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device, so that the device can automatically operate on thermal protector shells and metal shrapnel of different sizes, and automatically adapt to thermal protector shells of various specifications. Compared with the traditional assembly line that can only operate on thermal protector shells of one size at the same time, this device has better flexibility and adaptability.

[0014] Preferably, the docking assembly includes a motor, the motor is fixedly mounted on the top of the working chamber, a screw is fixedly mounted on the output end of the motor, the screw is placed on the inner wall of the working chamber, the outer wall of the screw is threadedly connected to a shift rack, a hollow shaft is fixedly mounted on the bottom of the shift rack, a round shaft is slidably connected to the inner wall of the hollow shaft, an air suction device is fixedly mounted on the bottom end of the round shaft, an air suction assembly is arranged inside the air suction device, the air suction assembly is used to use a vacuum pump to extract air from the suction cup to form a vacuum state, and use atmospheric pressure to adsorb the object on the surface of the suction cup to achieve grasping and moving of the object, when the intermittent conveyor belt drives the shell box to move into the working chamber, the intermittent conveyor belt stops moving, at this time, the motor drives the screw to move When the screw rotates, the screw drives the shift frame to move downward through the threaded transmission, and the shift frame drives the air suction device to move downward through the hollow shaft and the round shaft. When the air suction device contacts the metal shrapnel, the air suction component in the air suction device operates to grab the metal shrapnel. When the air suction device completes grabbing the metal shrapnel, the telescopic cylinder drives the two plate placing plates to move to both sides and open, and then controls the motor to continue to operate. When the metal shrapnel grabbed by the bottom of the air suction device contacts the inner wall of the thermal protector shell in the shell box, the motor stops working at this time, thereby realizing the docking between the metal shrapnel and the thermal protector shell, and playing the role of moving the metal shrapnel to dock with the inner wall of the thermal protector shell.

[0015] Preferably, the welding mechanism includes a welding box, which is slidingly connected to the inner wall of the air suction device, and the inner wall of the welding box is symmetrically provided with welding guns. The inner wall of the welding box is provided with an adjusting component and a capturing component, and the adjusting component is used to adjust the distance between the two welding guns, and the capturing component is used to drive the welding gun to capture and weld the welding position between the metal shrapnel and the protector shell. When the metal shrapnel and the inner wall of the thermal protector shell are connected, the two welding guns in the welding box weld the two. At the same time, the capturing component in the welding box captures and welds the welding point between the metal shrapnel and the protector shell, and cooperates with the adjusting component to adjust the distance between the two welding guns and the welding point, thereby realizing the welding of the metal shrapnel and the protector shell, and playing the role of welding the metal shrapnel and the protector shell.

[0016] Preferably, there are two groups of straightening plate assemblies, which include a rectangular shell, which is fixedly mounted on the outer wall of the welding gun, and the inner wall of the rectangular shell is symmetrically slidably connected to the limited sliding rod, and the bottom ends of the two limited sliding rods are fixedly mounted with pressing plates, and return springs are arranged between the tops of the two pressing plates and the bottom of the rectangular shell, and the two return springs are respectively placed on the outsides of the two limited sliding rods, and the outer walls of the two pressing plates are slidably connected to the inner wall of the rectangular shell. When the air suction device moves down and contacts the metal spring sheet, the two pressing plates will be pressed The limiting force of the metal spring sheet moves upward, and the two pressing plates will squeeze and push the return spring to slide on the rectangular shell. When the metal shrapnel is contacted, the two pressure plates stop moving, and under the elastic push of the reset spring, the metal shrapnel can be limited and squeezed into contact. When the air suction device drives the metal shrapnel to connect with the protector shell, the two welding guns in the welding box are driven to weld the two. When the welding gun welds the metal shrapnel, the welding gun drives the two pressure plates to move together through the rectangular shell, so that when the welding gun is welding, the pressure plate levels the metal shrapnel to prevent the presence of a gap between the metal shrapnel and the protector shell during welding, which affects the welding quality and plays a role in leveling the gap between the metal shrapnel and the protector shell.

When the motor drives the air suction device to move downward to grab the metal spring piece, when the height of the metal spring piece is too high, the air suction device will be limited by the height of the metal spring piece and move upward. When the air suction device moves upward, the air suction device drives the plurality of gear rods to move upward, and the gear rods will drive the gear plate and the welding box to move downward through the meshing transmission of the gears, so that the two welding guns are moved to the welding point, thereby ensuring that no matter how high the metal spring is, the positions of the two welding guns are always at the welding point between the metal spring and the protector shell, thereby ensuring the welding position of the two welding guns.

[0018] Preferably, a calibration rod is fixedly installed at the bottom of the rectangular shell, and a control button is fixedly installed at the bottom of the calibration rod. The bottom end height of the calibration rod is higher than the bottom end height of the welding gun. When the gear rod drives the gear plate and the welding box to move downward through the meshing transmission of the gears, the welding box also drives the calibration rod to move downward. When the control button at the bottom end of the calibration rod moves downward and contacts the plate, the drive motor stops operating. At this time, the positions of the two welding guns can be completely adjusted. When the air suction device drives the metal spring sheet to dock with the protector shell, when the control button at the bottom end of the calibration rod contacts the inner wall of the protector shell, it means that the bottom of the metal spring sheet is in contact with the inner wall of the protector shell, thereby controlling the motor to stop moving, thereby calibrating the contact between the metal spring sheet and the protector shell.

When the air suction device contacts the metal spring piece, at this time, the two pressing plates stop moving, and under the elastic push of the reset spring, the metal spring piece can be limited and squeezed into contact. When the metal spring piece and the protector shell are connected, when the welding gun welds the metal spring piece, the welding gun drives the two pressing plates to move together through the moment shell, so that when the welding gun is welding, the pressing plate will level the metal spring piece to prevent the existence of a gap between the metal spring piece and the protector shell during welding, which affects the welding quality and plays a role in leveling the gap between the metal spring piece and the protector shell.

[0021] 2. The thermal protector shell welding equipment described in the present invention drives the air suction device to move downward by a motor to grab the metal spring piece.

When the air suction device moves upward, it drives multiple gear rods to move upward, and the gear rods will drive the gear plate and the welding box to move downward through the meshing transmission of the gears, so that the two welding guns are moved to the welding point, thereby ensuring that no matter how high the metal spring is, the positions of the two welding guns are always at the welding point between the metal spring and the protector shell, thereby ensuring the welding position of the two welding guns.

[0022] 3. The thermal protector shell welding equipment described in the present invention, when the screw is driven to rotate by the motor, the screw drives the shift frame to move downward through the threaded transmission, and the shift frame drives the air suction device to move downward through the hollow shaft and the round shaft. When the air suction device contacts the metal spring piece, the air suction component in the air suction device operates to grab the metal spring piece. When the air suction device completes grabbing the metal spring piece, the telescopic cylinder drives the two plate placing plates to move to both sides and open, and then controls the motor to continue to operate. When the metal spring piece grabbed by the bottom of the air suction device contacts the inner wall of the thermal protector shell in the shell placing box, the motor stops working at this time, thereby realizing the docking between the metal spring piece and the thermal protector shell, playing the role of moving the metal spring piece to dock with the inner wall of the thermal protector shell.

[0023] 4. The thermal protector shell welding equipment described in the present invention fixes the protector shell in place by moving multiple solid shell blocks. The identification component in the feeding device detects and identifies the specifications of the thermal protector shell in the shell box through the detection head, and then drives the feeding component to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device, so that the device can automatically operate on thermal protector shells and metal shrapnel of different sizes, and automatically adapt to thermal protector shells of various specifications. Compared with the traditional assembly line that can only operate on thermal protector shells of one size at the same time, the present device has better flexibility and adaptability.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 9As shown, a thermal protector shell welding device described in an embodiment of the present invention includes an intermittent conveyor belt 1, a plurality of shell boxes 6 are arranged on the top of the intermittent conveyor belt 1, and a solid shell assembly is arranged inside the plurality of shell boxes 6, and the solid shell assembly is used to fix the thermal protector shell, and a working chamber 5 is fixedly installed on the top of the intermittent conveyor belt 1, and a docking assembly is arranged inside the working chamber 5, and the docking assembly is used to align and contact the metal spring piece and the protector shell, and a welding mechanism is arranged inside the working chamber 5, and the welding mechanism is used to weld the metal spring piece and the protector shell, and a straightening assembly is arranged inside the working chamber 5, and the straightening assembly includes a pressing plate 903, and the straightening assembly is used to drive the pressing plate 903 to flatten the metal spring piece, and the straightening assembly is placed on both sides of the welding mechanism, and the docking assembly is placed above the welding mechanism, and the positions of the solid shell assembly and the docking assembly can be placed on the same horizontal line;

[0039] Since the metal spring has a certain plasticity, there will be a certain gap between it and the shell of the thermal protector when they are aligned and placed. When the two are welded, a large weld or weld scar will be produced between them, which affects the welding quality and the aesthetics of the welding.

[0040] The heat protector shell is placed in the shell box 6, and the solid shell component in the shell box 6 fixes it to prevent the protector shell from shaking when the metal spring piece and the protector shell are welded, thereby affecting the welding effect. Then the intermittent conveyor belt 1 drives the shell box 6 to move. When the shell box 6 moves into the working chamber 5, the docking component drives the metal spring piece and the protector shell to align and contact. When the alignment and contact between the two are completed, the welding mechanism welds the metal spring piece and the protector shell. At the same time of welding, the sheet correction component drives the sheet pressing plate 903 to flatten the metal spring piece to prevent the metal The shrapnel and the thermal protector shell are not in full contact, and there is a gap between them, which affects the welding effect and the aesthetics after welding. It is more conducive to the welding operation between the metal shrapnel and the protector shell, and plays a role in making the metal shrapnel and the protector shell in full contact. When the welding of the two is completed, the intermittent conveyor belt 1 drives the shell box 6 to move from the working chamber 5, and drives the next shell box 6 to move into the working chamber 5 to carry out the welding between the next metal shrapnel and the protector shell, thereby realizing the automatic welding between the two, repeating the cycle, which can speed up the production efficiency and is more conducive to production.

[0041] like Figures 1 to 3As shown, a feeding device 2 is fixedly installed on one side of the intermittent conveyor belt 1, a batching robot arm 3 is fixedly installed on the top of the feeding device 2, a material placement trough plate 301 is fixedly installed on the top of one side of the feeding device 2, the batching robot arm 3 is placed on one side of the material placement trough plate 301 and is placed between the working chamber 5 and the feeding device 2, and a feeding component and an identification component are arranged inside the feeding device 2, the identification component is used to identify the specifications and dimensions of the thermal protector shell in the shell box 6, and the feeding component is used to throw the metal shrapnel matching the thermal protector shell out of the feeding device 2;

[0042] During operation, the specification and size of the thermal protector shell in the shell box 6 are identified through the identification component in the feeding device 2, and then the feeding component is driven to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device 2. When the metal shrapnel is thrown out, the metal shrapnel is driven to move to the specified position in the working chamber 5 by controlling the batching robot arm 3, which plays the role of moving and assembling the metal shrapnel.

[0043] like Figure 1 to Figure 2 As shown, a gantry 4 is fixedly installed on the top of the intermittent conveyor belt 1, and a plurality of detection heads 401 are fixedly installed on the inner wall of the gantry 4;

[0044] During operation, when the intermittent conveyor belt 1 drives the shell box 6 to move, the detection head 401 at the bottom of the gantry 4 detects the outer shell of the thermal protector placed in the shell box 6. When the detection head 401 completes the detection, it is transmitted to the feeding device 2 through the information system. The identification component in the feeding device 2 will control the feeding component to throw out the metal shrapnel that is compatible with the outer shell of the thermal protector in the shell box 6 according to the message transmitted back by the detection head 401, thereby playing a detection role.

[0045] like Figure 3 to Figure 4 As shown, the inner wall of the working chamber 5 is symmetrically fixedly installed with a telescopic cylinder 701, and the inner wall of the working chamber 5 is symmetrically slidably connected with a sheet placing plate 7, and the output ends of the two telescopic cylinders 701 are respectively fixedly connected to the outer walls of the two sheet placing plates 7, and the setting height of the two sheet placing plates 7 is consistent with the inner wall height of the material placing trough plate 301;

[0046] When the batching robot arm 3 drives the metal spring sheet into the working chamber 5, the batching robot arm 3 drives the metal spring sheet to move to the center position between the two placement plates 7, thereby placing the metal spring sheet. When the docking assembly drives it to align with the thermal protector shell, the telescopic cylinder 701 drives the two placement plates 7 to open to both sides to provide a path for the two to dock. When the welding mechanism completes the welding of the metal spring sheet and the protector shell, the docking assembly is reset, and the telescopic cylinder 701 will drive the two placement plates 7 to move and reset again to form a complete placement plate, thereby providing a placement point for the next metal spring sheet, playing the role of placing the metal spring sheet. It should be noted here that the two placement plates 7 are in a closed state in the initial state.

[0047] like Figures 8 to 9 As shown, the solid shell assembly includes a solid shell block 601, and there are multiple solid shell blocks 601. The outer walls of the multiple solid shell blocks 601 are all slidably connected to the inner wall of the shell box 6. A push block spring 602 is provided between one side of the multiple solid shell blocks 601 and the inner wall of the shell box 6. The tops of the multiple solid shell blocks 601 are all inclined sliding surfaces, and the protector shell is fixed between the multiple solid shell blocks 601.

[0048] Before working, by placing the protector shell in the shell box 6, when the protector shell moves in the shell box 6, the outer wall of the protector shell will squeeze the multiple solid shell blocks 601 in the shell box 6 to move, and when the protector shell moves and contacts the inner wall of the shell box 6, the shell box 6 is stopped at this time, and the multiple solid shell blocks 601 in the shell box 6 will fix the entering protector shell under the elastic push of the push block spring 602, thereby fixing the protector shell. The identification component in the feeding device 2 detects and identifies the specifications of the thermal protector shell in the shell box 6 through the detection head 401, and then drives the feeding component to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device 2, so that the device can automatically operate on thermal protector shells and metal shrapnel of different sizes, and play the role of automatically adapting to thermal protector shells of various specifications. Compared with the traditional assembly line that can only operate on thermal protector shells of one size at the same time, the present device has better flexibility and adaptability.

[0049] like Figures 4 to 6As shown, the docking assembly includes a motor 501, which is fixedly installed on the top of the working chamber 5, and a screw 502 is fixedly installed on the output end of the motor 501, and the screw 502 is placed on the inner wall of the working chamber 5. The outer wall of the screw 502 is threadedly connected with a shift frame 503, and a hollow shaft 801 is fixedly installed on the bottom of the shift frame 503. The inner wall of the hollow shaft 801 is slidably connected with a round shaft 802, and the bottom end of the round shaft 802 is fixedly installed with an air suction device 10, and an air suction assembly is arranged inside the air suction device 10. The air suction assembly is used to use a vacuum pump to extract the air in the suction cup to form a vacuum state, and use atmospheric pressure to adsorb the object on the surface of the suction cup to achieve the grasping and moving of the object;

[0050] When the intermittent conveyor belt 1 drives the shell box 6 to move into the working chamber 5, the intermittent conveyor belt 1 stops moving. At this time, the motor 501 drives the screw rod 502 to rotate. When the screw rod 502 rotates, the screw rod 502 drives the shift rack 503 to move downward through the threaded transmission. The shift rack 503 will drive the air suction device 10 to move downward through the hollow shaft 801 and the round shaft 802. When the air suction device 10 contacts the metal shrapnel, the air suction component in the air suction device 10 operates to grab the metal shrapnel. When the air suction device 10 completes grabbing the metal shrapnel, at this time, the telescopic cylinder 701 will drive the two plate placing plates 7 to move to both sides and open, and then control the motor 501 to continue to operate. When the metal shrapnel grabbed by the bottom of the air suction device 10 contacts the inner wall of the thermal protector shell in the shell box 6, the motor 501 stops working at this time, thereby realizing the docking between the metal shrapnel and the thermal protector shell, playing the role of moving the metal shrapnel to dock with the inner wall of the thermal protector shell.

[0051] like Figures 5 to 7 As shown, the welding mechanism includes a welding box 9, which is slidably connected to the inner wall of the air suction device 10, and the inner wall of the welding box 9 is symmetrically provided with welding guns 902. The inner wall of the welding box 9 is provided with an adjustment component and a capture component, the adjustment component is used to adjust the distance between the two welding guns 902, and the capture component is used to drive the welding gun 902 to capture the welding position between the metal spring piece and the protector shell;

[0052] When the metal spring piece is connected to the inner wall of the thermal protector shell, the two welding guns 902 in the welding box 9 weld the two. At the same time, the capture component in the welding box 9 captures and welds the welding point between the metal spring piece and the protector shell, and cooperates with the adjustment component to adjust the distance between the two welding guns 902 and the welding point, thereby realizing the welding of the metal spring piece and the protector shell, thereby playing the role of welding the metal spring piece and the protector shell.

[0053] like Figures 7 and 8As shown, there are two groups of straightening plate assemblies, which include a rectangular shell 905, which is fixedly mounted on the outer wall of the welding gun 902, and the inner wall of the rectangular shell 905 is symmetrically slidably connected to the limited sliding rod 907, and the bottom ends of the two limited sliding rods 907 are fixedly mounted with a pressing plate 903, and a return spring 906 is arranged between the top of the two pressing plates 903 and the bottom of the rectangular shell 905, and the two return springs 906 are respectively placed on the outside of the two limited sliding rods 907, and the outer walls of the two pressing plates 903 are slidably connected to the inner wall of the rectangular shell 905; a calibration rod 901 is fixedly mounted on the bottom of the rectangular shell 905, and a control button 904 is fixedly mounted on the bottom of the calibration rod 901, and the bottom end height of the calibration rod 901 is higher than the bottom end height of the welding gun 902;

[0054] When the air suction device 10 moves down and contacts the metal spring piece, the two pressing plates 903 will be moved upward by the limiting force of the compressed metal spring piece, and the two pressing plates 903 will squeeze and push the return spring 906 to slide on the rectangular shell 905. When the air suction device 10 contacts the metal spring piece, at this time, the two pressing plates 903 stop moving. Under the elastic push of the return spring 906, the metal spring piece can be limited and squeezed in contact. When the air suction device 10 drives the metal spring piece to connect with the protector shell, at this time, the two welding guns 902 in the welding box 9 are driven to weld the two. When the welding gun 902 welds the metal spring piece, the welding gun 902 drives the two pressing plates 903 to move together through the rectangular shell 905, so that when the welding gun 902 is welding, the pressing plate 903 levels the metal spring piece to prevent gaps between the metal spring piece and the protector shell during welding, which affects the welding quality and plays a role in leveling the gap between the metal spring piece and the protector shell.

[0055] like Figures 7 and 8 As shown, a rectangular box 8 is fixedly installed on the outer wall of the hollow shaft 801, an air suction device 10 is placed inside the rectangular box 8, a plurality of gear rods 803 are fixedly installed on the top of the air suction device 10, a plurality of tooth plates 908 are fixedly installed on the top of the welding box 9, and a plurality of gears 804 are rotatably connected to the inner wall of the rectangular box 8, and the teeth on the plurality of tooth plates 908 and the pressing plate 903 can respectively mesh with the teeth on the plurality of gears 804;

[0056] Since the heights of the metal springs are different, but the positions of the welding points of the metal springs and the protector housing are the same, when the motor 501 drives the air suction device 10 to move downward to grab the metal springs, when the height of the metal springs is too high, the air suction device 10 will be restricted by the height of the metal springs and move upward. When the air suction device 10 moves upward, the air suction device 10 drives multiple gear rods 803 to move upward, and the gear rods 803 will drive the gear plate 908 and the welding box 9 to move downward through the meshing transmission of the gear 804, so that the two welding guns 902 are moved to the welding point, thereby ensuring that no matter how high the metal spring is, the positions of the two welding guns 902 are always at the welding point between the metal spring and the protector housing, thereby ensuring the welding position of the two welding guns 902.

[0057] like Figure 6 to Figure 7 As shown, a calibration rod 901 is fixedly installed at the bottom of the rectangular housing 905, a control button 904 is fixedly installed at the bottom of the calibration rod 901, and the bottom end height of the calibration rod 901 is higher than the bottom end height of the welding gun 902;

[0058] When the gear rod 803 drives the gear plate 908 and the welding box 9 to move downward through the meshing transmission of the gear 804, the welding box 9 also drives the calibration rod 901 to move downward. When the control button 904 at the bottom of the calibration rod 901 moves downward and contacts the plate 7, the driving motor 501 stops working. At this time, the positions of the two welding guns 902 can be completely adjusted. When the air suction device 10 drives the metal spring to dock with the protector shell, when the control button 904 at the bottom of the calibration rod 901 contacts the inner wall of the protector shell, it means that the bottom of the metal spring contacts the inner wall of the protector shell, thereby controlling the motor 501 to stop moving, thereby calibrating the contact between the metal spring and the protector shell.

[0059] Working principle: The heat protector shell is placed in the shell box 6, and the solid shell component in the shell box 6 fixes it to prevent the protector shell from shaking when the metal spring piece and the protector shell are welded, thereby affecting the welding effect. Then the intermittent conveyor belt 1 drives the shell box 6 to move. When the shell box 6 moves into the working chamber 5, the docking component drives the metal spring piece and the protector shell to align and contact. When the alignment and contact between the two are completed, the welding mechanism welds the metal spring piece and the protector shell. At the same time of welding, the sheet correction component drives the sheet pressing plate 903 to flatten the metal spring piece to prevent The metal spring piece and the thermal protector shell are not in full contact, and there is a gap between the two, which affects the welding effect and the aesthetics after welding. It is more conducive to the welding operation between the metal spring piece and the protector shell, and plays a role in making the metal spring piece and the protector shell fully contact. When the welding of the two is completed, the intermittent conveyor belt 1 drives the shell box 6 to move from the working chamber 5, and drives the next shell box 6 to move into the working chamber 5 to perform the welding between the next metal spring piece and the protector shell, so as to realize the automatic welding between the two, which is repeated over and over again, and can speed up the production efficiency and facilitate the production;

[0060] During operation, the specification and size of the thermal protector shell in the shell box 6 are identified by the identification component in the feeding device 2, and then the feeding component is driven to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device 2. When the metal shrapnel is thrown out, the batching mechanical arm 3 is controlled to drive the metal shrapnel to move to the specified position in the working chamber 5, which plays the role of moving and assembling the metal shrapnel;

[0061] During operation, when the intermittent conveyor belt 1 drives the shell box 6 to move, the detection head 401 at the bottom of the gantry 4 detects the shell of the thermal protector placed in the shell box 6. When the detection head 401 completes the detection, it is transmitted to the feeding device 2 through the information system. The identification component in the feeding device 2 will control the feeding component to throw out the metal spring that matches the shell of the thermal protector in the shell box 6 according to the message transmitted back by the detection head 401, so as to play a detection role;

[0062] When the batching robot arm 3 drives the metal spring sheet into the working chamber 5, the batching robot arm 3 drives the metal spring sheet to move to the center position between the two placement plates 7, so as to place the metal spring sheet. When the docking assembly drives it to align with the thermal protector shell, the telescopic cylinder 701 drives the two placement plates 7 to open to both sides to provide a path for the two to dock. When the welding mechanism completes the welding of the metal spring sheet and the protector shell, the docking assembly is reset, and the telescopic cylinder 701 drives the two placement plates 7 to move and reset again to form a complete placement plate, thereby providing a placement point for the placement of the next metal spring sheet, playing the role of placing the metal spring sheet.

[0063] Before working, by placing the protector shell in the shell box 6, when the protector shell moves in the shell box 6, the outer wall of the protector shell will squeeze the multiple solid shell blocks 601 in the shell box 6 to move, and when the protector shell moves and contacts the inner wall of the shell box 6, the shell box 6 is stopped at this time, and the multiple solid shell blocks 601 in the shell box 6 will fix the entering protector shell under the elastic push of the push block spring 602, thereby fixing the protector shell. The identification component in the feeding device 2 detects and identifies the specifications of the thermal protector shell in the shell box 6 through the detection head 401, and then drives the feeding component to drive the metal shrapnel matching the thermal protector shell to be thrown out from the feeding device 2, so that the device can automatically operate on thermal protector shells and metal shrapnel of different sizes, and play the role of automatically adapting to thermal protector shells of various specifications. Compared with the traditional assembly line that can only operate on thermal protector shells of one size at the same time, the device has better flexibility and adaptability;

[0064] When the intermittent conveyor belt 1 drives the shell box 6 to move into the working chamber 5, the intermittent conveyor belt 1 stops moving. At this time, the motor 501 drives the screw rod 502 to rotate. When the screw rod 502 rotates, the screw rod 502 drives the shift frame 503 to move downward through the threaded transmission. The shift frame 503 will drive the air suction device 10 to move downward through the hollow shaft 801 and the round shaft 802. When the air suction device 10 contacts the metal spring, the air suction component in the air suction device 10 operates to grab the metal spring. When the air suction device 10 completes grabbing the metal spring, the telescopic cylinder 701 drives the two plate plates 7 to move to both sides and open, and then controls the motor 501 to continue to operate. When the metal spring grabbed by the bottom of the air suction device 10 contacts the inner wall of the thermal protector shell in the shell box 6, the motor 501 stops working at this time, thereby realizing the docking between the metal spring and the thermal protector shell, playing the role of moving the metal spring to dock with the inner wall of the thermal protector shell;

[0065] When the metal spring piece is connected to the inner wall of the thermal protector shell, the two welding guns 902 in the welding box 9 weld the two. At the same time, the capture component in the welding box 9 captures and welds the welding point between the metal spring piece and the protector shell, and cooperates with the adjustment component to adjust the distance between the two welding guns 902 and the welding point, so as to achieve the welding of the metal spring piece and the protector shell, and play the role of welding the metal spring piece and the protector shell;

[0066] When the air suction device 10 moves down and contacts the metal spring sheet, the two pressing plates 903 will be moved upward by the limiting force of the compressed metal spring sheet, and the two pressing plates 903 will squeeze and push the return spring 906 to slide on the rectangular shell 905. When the air suction device 10 contacts the metal spring sheet, at this time, the two pressing plates 903 stop moving. Under the elastic push of the return spring 906, the metal spring sheet can be limited and squeezed in contact. When the air suction device 10 drives the metal spring sheet to dock with the protector shell, at this time, the two welding guns 902 in the welding box 9 are driven to weld the two. When the welding gun 902 welds the metal spring sheet, the welding gun 902 drives the two pressing plates 903 to move together through the rectangular shell 905, so that when the welding gun 902 is welding, the pressing plate 903 levels the metal spring sheet to prevent gaps between the metal spring sheet and the protector shell during welding, which affects the welding quality and plays a role in leveling the gap between the metal spring sheet and the protector shell.

[0067] When the motor 501 drives the air suction device 10 to move downward to grab the metal spring, when the height of the metal spring is too high, the air suction device 10 will be limited by the height of the metal spring and move upward. When the air suction device 10 moves upward, the air suction device 10 drives the multiple gear rods 803 to move upward, and the gear rods 803 drive the gear plate 908 and the welding box 9 to move downward through the meshing transmission of the gear 804, so that the two welding guns 902 move to the welding point, thereby ensuring that no matter how high the metal spring is, the positions of the two welding guns 902 are always at the welding point between the metal spring and the protector housing, which plays a role in ensuring the welding position of the two welding guns 902;

[0068] When the gear rod 803 drives the gear plate 908 and the welding box 9 to move downward through the meshing transmission of the gear 804, the welding box 9 also drives the calibration rod 901 to move downward. When the control button 904 at the bottom of the calibration rod 901 moves downward and contacts the plate 7, the driving motor 501 stops working. At this time, the positions of the two welding guns 902 can be completely adjusted. When the air suction device 10 drives the metal spring to dock with the protector shell, when the control button 904 at the bottom of the calibration rod 901 contacts the inner wall of the protector shell, it means that the bottom of the metal spring contacts the inner wall of the protector shell, thereby controlling the motor 501 to stop moving, thereby calibrating the contact between the metal spring and the protector shell.
