Laser processing system and method

Abstract

The invention relates to a laser processing system, which comprises a laser for generating laser beam, a variable-focus lens device for focusing said laser beam to the target part of work piece, a controller for controlling the working parameters of laser, and a feedback device for feeding back information which can detect and treat the information of target part and feedback said information to the lens device and controller, to adjust the focus and optimize the working parameters of laser. Said system can keep the light spot on the target part at preset size, to realize treatment accurately. And the invention also provides relative method.

Description

A laser processing system and processing method 【Technical field】 The invention relates to a material processing system and a processing method, in particular to a laser processing system and a processing method for high-precision processing of materials. 【Background technique】 With the continuous development of the 3C (computer, communication and consumer electronics) industry, it is becoming more and more important to realize high-precision processing of 3C products. At present, the frame parts of 3C products are often processed by stamping. Stamping, that is, to apply pressure or tension to the sheet through the die to form a shear force to remove the excess part of the sheet and shape the sheet to obtain a product with a certain size, shape and performance. However, since the excess part of the separated plate cannot be used again, it will become a waste material, thereby causing a waste of raw materials and resulting in higher processing costs. The laser processin...

Problems solved by technology

However, 3C products such as computers, communications, and consumer electronics require high processing precision, and most of their shape and structure designs are relatively complicated. During the process of moving the workpiece horizontally for laser processing, the irregular shape structure on the surface of the workpiece For example, protrusions or depressions will change the distance between it and the lens. Since the focal length of the converging lens is fixed, it will cause the size of the focused spot irradiated on the workpiece to be processed to change, resulting in low processing accuracy.
