Description

Technical Field

[0001] This utility model relates to the field of electronic component welding technology, and in particular to a fully automatic capacitor negative electrode cover welding machine. Background Technology

[0002] In the production process, it is necessary to press the negative terminal cover of the capacitor onto the capacitor body, and then weld the pressed negative terminal cover onto the capacitor body.

[0003] Currently, the two production steps of pressing the negative electrode cover to the capacitor body and then welding the pressed negative electrode cover to the capacitor body are performed manually. Specifically, a person takes a negative electrode cover and a capacitor body from the incoming material box, assembles them, and places them into a high-frequency pressing assembly. The high-frequency pressing assembly instantly heats the negative electrode cover to soften it, and then presses the negative electrode cover and capacitor body together to achieve an interference fit. After cooling, the combined negative electrode cover and capacitor body are removed and placed in the designated position of the laser welding assembly for laser welding. The entire process requires manual handling, transportation, waiting, clamping, and unclamping. This increases labor and time costs and makes it difficult to control the yield rate.

[0032] In this embodiment, the structures of the capacitor infeed conveyor line 200, the negative electrode cover infeed conveyor line 100, and the finished product unfeed conveyor line 1100 are basically the same, such as... Figure 3As shown, the capacitor body 250 is composed of a base bracket 220, a motor 230, a guide rail 210, and a pulley structure 240.

[0051] 8. Camera 950 uses light source 920 to illuminate and detect defective products;

[0052] 9. The rotating clamping cylinder base 963 rotates to drive the capacitor body 250 to rotate, and then the laser welding assembly 1000 performs laser welding on the capacitor body 250 and the pressed negative electrode cover.

[0053] 10. The good products welded by robot component 800 are placed on finished product unloading conveyor line 1100, while the defective products are placed in defective product box 30.
