Background

The laser welding equipment needs to work stably, and the most important is to ensure that the welded surface is within the focal distance of the lens of the laser machine. For products with inconsistent pad positions, the most direct method is to fix the laser welding lens on the moving module, and when pads with different heights are welded, the module moves the laser welding lens to the corresponding height. This solution has several drawbacks. Firstly, it needs extra module, and the cost is higher, and it is very big to reform transform the equipment of current no module. Secondly, there is a problem of vibration after moving the laser head, which is not favorable for stable welding. Finally, this solution does not allow to achieve an accurate welding for products with a consistent design value but with a large tolerance in the height direction.
