Problems solved by technology

However, this processing method will lead to inaccurate processing
For example, when processing soft boards, the product may be deformed after the pre-processing station is processed, resulting in changes in the position of the feature points on the product. If these feature points are used to point the product for processing, it will lead to inaccurate processing.

Abstract

The invention discloses a laser processing method, laser processing equipment and a storage medium. The method comprises the steps that a product is divided into a plurality of galvanometer machining areas, and the center of each galvanometer machining area is a machining point of the corresponding galvanometer machining area; dividing the product into a plurality of camera shooting effective areas, wherein the center of each camera shooting effective area is a shooting point of each camera shooting effective area; a product is sequentially moved to all machining points, a plurality of mark points are marked in galvanometer machining areas corresponding to all the machining points through laser, and a coordinate matrix of the mark points of each galvanometer machining area in a galvanometer coordinate system is that the mark points of the galvanometer machining areas corresponding to all the machining points are sequentially moved to corresponding photographing points for photographing; obtaining a coordinate matrix of the mark point in each galvanometer processing area in a camera coordinate system, establishing a conversion matrix between the coordinate matrix and the conversion matrix, and completing camera correction; and after correction is completed, machining areas of the galvanometers are machined in sequence, and large-breadth and high-precision laser machining is achieved.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser processing method, laser processing equipment and a storage medium. Background technique [0002] At present, the cutting of large-format circuit boards mainly uses milling machine cutting and laser cutting. Compared with milling machine cutting, laser cutting improves processing efficiency and section quality, especially for soft boards that cannot be cut by milling machines. [0003] In the commonly used laser processing of large-format circuit boards, a camera is used to locate several feature points on the product to locate the product for processing. However, this processing method will lead to inaccurate processing. For example, when processing soft boards, the product may be deformed after the pre-processing station is processed, resulting in changes in the position of the feature points on the product. If these feature points are used to point the produc...
