Description

Technical Field

[0001] The invention belongs to the technical field of jig development, and in particular relates to a special jig for welding silver contacts of soft copper bars. Background Art

[0002] There is a special-shaped soft copper busbar, such as Figure 1 As shown, a silver contact needs to be welded at one end of the soft copper busbar. However, the traditional silver contact welding process for the soft copper busbar usually requires workers to place it manually or suck it with a suction gun and then place it on the silver contact area of ​​the soft copper busbar for induction welding. The silver contact is very small and thin (diameter: 7.2, thickness: 1.15mm), but the welding position must be precise and it cannot be offset after welding. Since the silver contact is very small, it is not easy to place it accurately using the traditional placement method. Even if it is placed accurately, it is easy to shift or deviate due to slight vibrations before welding. It is also very easy to deviate or slip during the welding process, which finally causes the silver contact to deviate and skew after induction welding, affecting product quality.

[0003] Therefore, a special fixture for welding silver contacts of soft copper busbars is designed to solve the above problems. Summary of the invention
