Description

Technical Field

[0001] The utility model relates to the technical field of resistance pin welding, in particular to a resistance pin welding device for resistance processing. Background Technique

[0002] When processing metals or other thermoplastic materials, welding is often required. Resistance components are important and widely used electronic components. A resistance component includes a resistance body and pins. During production and processing, it is necessary to extract specific lengths of resistance bodies and pins from bundled materials respectively. At this time, a resistance welding device is needed to perform pin welding operations on the resistance.

[0003] The existing welding devices for thermistor chips need operators to manually align the resistance with the pin ends for welding. This welding method requires welding each resistance one by one, with low welding operation efficiency, and manual fixation is prone to generate shaking during welding, thus affecting the welding quality. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a resistance pin welding device for resistance processing to solve the technical problems raised in the above background technique.

One end of the connecting plate is movably installed with a positioning plate, and both ends of the positioning plate are fixedly installed with limiting plates. One end of the limiting plate is movably installed with a clamping plate, and the other end of the limiting plate is movably installed with a supporting plate. Guide grooves matching with the clamping plate and the supporting plate are opened at both ends of the limiting plate. One end of the positioning plate is movably installed with a first placement block, and the other end of the positioning plate is fixedly installed with a second placement block. The clamping plate and the supporting plate are connected to the first placement block through a connecting rod.

[0006] By adopting the above technical solution, the first placement block drives the clamping plate and the supporting plate to move along the guide groove through the connecting rod, so that the clamping plate and the supporting plate move towards each other. The supporting plate supports one end of the resistance pin, and at the same time, the limiting groove opened at one end of the clamping plate starts to insert into the fixing grooves of the first placement block and the second placement block, so that the clamping plate limits one end pin of the resistance placed on the first placement block and the second placement block, thereby completing the butt joint positioning of the resistance pin, and cooperating with the supporting plate to fix and clamp the resistance, thus avoiding the problem that the shaking during the resistance pin welding affects the welding quality.

A driving motor is fixedly installed at one end of the guiding slide rail, and a first threaded rod is movably installed at the output end of the driving motor. The positioning plate and the first threaded rod are connected through a connecting block.

[0008] By adopting the above technical solution, by installing the first threaded rod, the first threaded rod can achieve precise linear motion control. By adjusting the rotation angle or the number of turns of the first threaded rod, the moving distance can be precisely controlled, so that the device can perform high-precision positioning for resistance welding and improve the welding quality.

[0009] The present utility model is further configured such that a hydraulic cylinder is fixedly installed at one end of the operating table, a hydraulic rod is movably installed at one end of the hydraulic cylinder, and a welding head is fixedly installed at one end of the hydraulic rod.

A rotating handle is movably installed at one end of the operating table, and the rotating handle and the first placing block are connected through a second threaded rod.

[0012] By adopting the above technical solution, by providing the limiting groove and inserting the limiting groove into the fixing grooves of the first placing block and the second placing block, the clamping plate limits the pins at one end of the resistor placed on the first placing block and the second placing block, thereby completing the butt joint positioning of the resistor pins, and cooperating with the supporting plate to quickly fix and clamp the resistor.

[0013] The present utility model is further configured such that the operating table and the connecting plate are connected through a fixed bottom plate, and a supporting base is fixedly installed at one end of the operating table.

[0014] By adopting the above technical solution, by installing the supporting base, the device obtains better supporting force and is more stable during the operation and use of the device.

[0024] The following will describe the embodiments according to the overall structure of the present utility model.

[0025] A resistance pin welding device for resistance processing, as Figures 1-4 shown, includes an operation table 1 and a connecting plate 7. One end of the connecting plate 7 is movably installed with a positioning plate 10, and both ends of the positioning plate 10 are fixedly installed with limiting plates 14. One end of the limiting plate 14 is movably installed with a clamping plate 17, and the other end of the limiting plate 14 is movably installed with a supporting plate 24. Both ends of the limiting plate 14 are provided with guiding grooves 15 that cooperate with the clamping plate 17 and the supporting plate 24. One end of the positioning plate 10 is movably installed with a first placing block 20, and the other end of the positioning plate 10 is fixedly installed with a second placing block 21. The clamping plate 17 and the supporting plate 24 are connected to the first placing block 20 through a connecting rod 16. When the first placing block 20 moves horizontally and moves towards one end of the second placing block 21, the first placing block 20 drives the clamping plate 17 and the supporting plate 24 to move along the guiding groove 15 through the connecting rod 16, so that the clamping plate 17 and the supporting plate 24 move towards each other, enabling the supporting plate 24 to support one end of the resistance pin. At the same time, the limiting groove 23 opened at one end of the clamping plate 17 starts to insert into the fixing grooves 22 of the first placing block 20 and the second placing block 21, enabling the clamping plate 17 to limit the resistance pins at one end placed on the first placing block 20 and the second placing block 21, thereby completing the butt joint positioning of the resistance pins and cooperating with the supporting plate 24 to fix and clamp the resistance.

[0026] Please refer to Figure 2 , both ends of the connecting plate 7 are provided with guiding slide rails 9 that cooperate with the positioning plate 10. One end of the guiding slide rail 9 is fixedly installed with a driving motor 13, and the output end of the driving motor 13 is movably installed with a first threaded rod 12. The positioning plate 10 and the first threaded rod 12 are connected through a connecting block 11. By installing the first threaded rod 12, the first threaded rod 12 can achieve precise linear motion control. By adjusting the rotation angle or the number of turns of the first threaded rod 12, the moving distance can be precisely controlled, so that the device can perform high-precision positioning for resistance welding and improve the welding quality.

[0027] Please refer to Figure 1 , one end of the operation table 1 is fixedly installed with a hydraulic cylinder 3, and one end of the hydraulic cylinder 3 is movably installed with a hydraulic rod 4. One end of the hydraulic rod 4 is fixedly installed with a welding head 5. By installing the hydraulic rod 4, the hydraulic rod 4 can maintain high stability and reliability during the operation of the device, and has good buffering and vibration damping effects, thereby ensuring the welding accuracy.

[0028] Please refer to Figure 4 , multiple groups of fixing grooves 22 are provided on the surfaces of the first placing block 20 and the second placing block 21. A limiting groove 23 matching the fixing groove 22 is provided at one end of the clamping plate 17, and a positioning hole 18 matching the welding head 5 is provided at one end of the clamping plate 17. A rotating handle 8 is movably installed at one end of the operating table 1, and the rotating handle 8 and the first placing block 20 are connected by a second threaded rod 19. By providing the limiting groove 23 and inserting the limiting groove 23 into the fixing grooves 22 of the first placing block 20 and the second placing block 21, the clamping plate 17 limits one end pin of the resistor placed on the first placing block 20 and the second placing block 21, thereby completing the docking and positioning of the resistor pins, and cooperating with the support plate 24 to quickly fix and clamp the resistor.

[0029] Please refer to Figure 1 , the operating table 1 and the connecting plate 7 are connected by a fixed bottom plate 6, and a support base 2 is fixedly installed at one end of the operating table 1. By installing the support base 2, the device obtains better support force and is more stable when the device is running and in use.

[0030] The working principle of the present utility model is as follows: When in use, first place the resistor to be welded into the fixing groove 22, and then rotate the rotating handle 8, so that the second threaded rod 19 rotates and pushes the first placing block 20 to move towards the second placing block 21. During the horizontal movement of the first placing block 20 towards one end of the second placing block 21, the first placing block 20 drives the clamping plate 17 and the support plate 24 to move along the guiding groove 15 through the connecting rod 16, so that the clamping plate 17 and the support plate 24 move towards each other, enabling the support plate 24 to support one end of the resistor pin. At the same time, the limiting groove 23 provided at one end of the clamping plate 17 starts to be inserted into the fixing grooves 22 of the first placing block 20 and the second placing block 21, so that the clamping plate 17 limits one end pin of the resistor placed on the first placing block 20 and the second placing block 21, thereby completing the docking and positioning of the resistor pins, and cooperating with the support plate 24 to fix and clamp the resistor. At this time, start the driving motor 13, drive the first threaded rod 12 to rotate through the driving motor 13, so that the positioning plate 10 can move horizontally along the guiding slide rail 9, thereby cooperating with the lifting of the hydraulic rod 4 to drive the welding head 5 to move, so that the welding head 5 is quickly inserted into the positioning hole 18 in sequence to perform high-precision welding on the resistor fixed and clamped by the clamping plate 17 and the support plate 24. After the resistor is welded, rotate the rotating handle 8, so that the rotating handle 8 drives the first placing block 20, the clamping plate 17, and the support plate 24 to reset through the second threaded rod 19, and take out the resistor, and that's it.
