Laser pressure welding mechanism for manufacturing composite plate

The utility model relates to the technical field of composite board manufacturing. The utility model relates to a welding mechanism, in particular to a laser pressure welding mechanism for manufacturing composite plates. The device comprises a laser generator, a laser moving mechanism, a focus lens, a focus lens moving mechanism, a fixed roller and a movable roller, the laser generator is driven by the laser moving mechanism to move. The focusing mirror is driven by the focusing mirror moving mechanism to move; two plates are input between the fixed roller and the movable roller; wherein the fixed roller and the movable roller are arranged on the two plates, an alpha angle area is formed between the two plates, a laser beam emitted by the laser generator is focused by the focusing lens toform a linear light spot and refracted into the angle end of the alpha angle area, the laser generator and the focusing lens synchronously reciprocate in the Y direction, and the two plates are in pressure connection through
