Description

Technical Field

[0002] Traditional laser processing equipment generally adopts paraxial optical path. The camera component and the laser component each have their own optical path. There is a center distance between the camera and laser optical paths. The camera working center and the laser working center are two different routes. The paraxial optical path uses a single reflective lens without a semi-transparent and semi-reflective function. In addition, traditional laser processing equipment will install the power meter at the laser light outlet. When testing at the laser light outlet, accurate data will not be obtained, and the power will also be lost. It is not the real power data of the workbench. Or some equipment will install the power meter on the processing platform. The power meter moves with the processing platform. The platform's spatial travel needs to be increased, and the cable routing space needs to be considered, etc., which is costly and troublesome to maintain. In the context of market refinement, the product processing performance of the equipment is getting higher and higher. The existing paraxial optical path and the power meter installation position occupy a large space, and the structural layout can no longer meet customer needs. For this reason, a coaxial optical path and narrow space power test laser processing equipment is proposed. Utility Model Content
