[0022] Embodiment

[0023] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a pin welding device for capacitor processing includes a workbench 1. A rotating shaft 3 is rotatably arranged inside the workbench 1. A turntable 7 is arranged at the top of the rotating shaft 3. A worm gear 4 is also connected to the rotating shaft 3 inside the workbench 1 by key connection. A worm 5 is rotatably arranged inside the workbench 1. The worm 5 meshes with the worm gear 4. At this time, rotating the worm 5 can drive the rotating shaft 3 to rotate through the worm gear 4, thereby driving the turntable 7 to rotate. In addition, due to the self-locking function of the worm gear 4 and the worm 5, the angle of the turntable 7 after rotation can be limited, so that the device can better meet the actual use requirements, and thus ensure the quality of subsequent welding. An electric motor 6 is arranged on the front outer wall of the workbench 1. The power output shaft of the electric motor 6 is connected to the worm 5 through a coupling. By using the electric motor 6, the worm 5 can be driven to rotate, and then the turntable 7 can be driven to rotate.

[0024] A number of placement racks 8 are evenly arranged on the top of the turntable 7. An installation rack 2 is also arranged on the top of the workbench 1. An electric push rod 12 is arranged at the bottom of the installation rack 2. The end of the telescopic arm at the bottom of the electric push rod 12 is provided with a mounting plate 13. A number of sliding rods 14 are evenly arranged on the mounting plate 13. The end of the bottom of the sliding rod 14 is provided with a pressing plate 16. A welding machine 17 is also arranged at the bottom of the mounting plate 13. During actual use, when welding the pins of a capacitor is required, the staff places the capacitor on the placement rack 8. Then, the electric push rod 12 is used to drive the pressing plate 16 to move downward. When the bottom of the pressing plate 16 contacts the capacitor, under the action of the sliding rod 14, the mounting plate 13 continues to descend, so that the welding machine 17 descends, and thus the welding machine 17 can weld the pins of the capacitor. A second return spring 15 is also sleeved outside the sliding rod 14. One end of the second return spring 15 is connected to the mounting plate 13, and the other end of the second return spring 15 is connected to the pressing plate 16. At this time, under the action of the second return spring 15, the pressing plate 16 can be reset, and thus the pressing plate 16 can better press and fix the capacitor, reducing the occurrence of the situation where the welding quality is reduced due to insufficient fixation of the capacitor during actual welding, ensuring the welding quality of the capacitor pins. A limiting plate 1401 is also arranged on the sliding rod 14. Under the action of the limiting plate 1401, the situation of the sliding rod 14 falling off is reduced, ensuring the service efficiency of the sliding rod 14.

[0025] A slide rail 9 is also arranged inside the placement rack 8. Two clamping plates 10 are slidably arranged on the slide rail 9. A first return spring 11 is also sleeved on the slide rail 9. One end of the first return spring 11 is connected to the clamping plate 10, and the other end of the first return spring 11 is connected to the placement rack 8. Under the action of the clamping plate 10, the placement rack 8 can meet the clamping and fixing requirements for capacitors of different sizes. With the cooperation of the first return spring 11, the clamping and fixing quality of the clamping plate 10 for the capacitor is ensured, and thus the fixing quality of the device for the capacitor is improved. A rubber pad is also arranged on the inner wall of the clamping plate 10. Under the action of the rubber pad, the clamping and fixing quality of the clamping plate 10 for the capacitor is ensured, reducing the occurrence of the situation where the capacitor falls off.

[0026] In actual use, when it is necessary to weld the capacitor pins, the staff place several capacitors on the placement rack 8, clamp and fix the capacitors by using the clamping plate 10, and then start the motor 6 to drive the rotating shaft 3 to rotate by means of the worm 5 and the worm gear 4, so that the placement rack 8 moves below the mounting rack 2. At this time, the electric push rod 12 is used to drive the mounting plate 13 to move downward, so that the pressing plate 16 presses and fixes the capacitors. At this time, the welding of the capacitor pins can be completed by the welder 17. After the welding is completed, the turntable 7 is rotated to weld the capacitors on the next placement rack 8, so that the device can weld the capacitor pins more quickly, and to a certain extent, the welding efficiency of the device is improved.
