AI makes unmanned, accurate, efficient and intelligent detection become the standard configuration of module factories

Junction box welding machine (electromagnetic welding, electric resistance welding) (AI automatic recognition)

Adopting high-frequency induction welding technology, specifically designed for the welding of module junction box busbars, with fast welding speed, low consumables, and low usage cost.

Integrating OPT Al detection technology, it can identify defects in the junction box position and busbar status of welded modules. During the welding process, Al positioning is used, with high compatibility.

After the welding is completed, the discharge process is completed and the junction box is photographed. Al identifies welding defects and the work pace is short.
