Problems solved by technology
For laser processing of products of different materials, different defocus amounts need to be set, while traditional laser processing equipment using robots is usually used for laser cutting, welding, quenching, cladding, drilling, engraving, marking and metal For 3D printing and other purposes, different laser heads need to be replaced according to different uses, and the focus needs to be refocused after each replacement of the laser head. It is difficult to accurately determine the focus position and distance of the laser beam with the naked eye or the experience of the operator, and it cannot be visualized. Editing the laser processing path indiscriminately leads to uncontrollable situations in the laser processing process, so it is difficult to guarantee the quality of laser processing products, and the scrap rate remains high. Solving the above problems has become a top priority

The invention discloses an auxiliary focusing method for laser machining equipment. Laser beams are centered by using a centering device, and the positions of foci of the laser beams and the distance between the foci of every two laser beams are accurately determined by using a focus locator and a focus indicator. By using the auxiliary focusing method, the visualization of focus conversion in the editing process of a laser machining route is realized, the defocusing amount of the subsequent laser machining process is accurately controlled, furthermore, the quality of a laser machined product is greatly improved, and waste products are avoided.
Description
technical field [0001] The invention belongs to the field of laser processing, and in particular relates to an auxiliary focusing method for laser processing equipment. Background technique [0002] The application of laser in material processing is known as a revolution in manufacturing technology. Laser processing equipment is widely used in aerospace industry, shipbuilding industry, automobile industry and microelectronics industry. For laser processing of products of different materials, different defocus amounts need to be set, while traditional laser processing equipment using robots is usually used for laser cutting, welding, quenching, cladding, drilling, engraving, marking and metal For 3D printing and other purposes, different laser heads need to be replaced according to different uses, and the focus needs to be refocused after each replacement of the laser head. It is difficult to accurately determine the focus position and distance of the laser beam with the nake...
