Description

Technical Field

[0001] The utility model relates to the technical field of laser welding equipment, in particular to a laser automatic welding equipment. Background Art

[0002] At present, photovoltaic module welding equipment generally adopts two methods: hot pressing welding and electromagnetic welding:

[0003] 1) The hot pressing welding and cooling time is long, and the tin is easy to explode during the welding cooling process. Some processes require tin addition, which prolongs the equipment cycle and increases the product cost. It cannot meet the customer's equipment process speed-up and cost reduction issues;

[0004] 2) During electromagnetic welding, only one welding point can be welded at a time. The size of the welding head is easily limited by the space of the wire box. The life of the encapsulated and unencapsulated welding heads is greatly affected by the manufacturing process. The number of uses is unstable and cannot meet customer requirements.

However, during the assembly process of the soldering ribbon and the junction box, the soldering ribbon may bend or wrinkle, which may lead to poor welding between the soldering ribbon and the conductive electrode of the junction box, thereby reducing the production qualification rate.
