Laser cutting device, equipment and method

Abstract

The embodiment of the invention discloses a laser cutting device, equipment and method, the laser cutting device comprises a first light emitting part and a second light emitting part, and the first light emitting part is configured as a laser emitting end; the second light emitting part is configured to be a laser emitting end, and a light outlet of the second light emitting part and a light outlet of the first light emitting part are oppositely arranged. According to the embodiment of the invention, the first light emitting part and the second light emitting part which have the laser emitting function are adopted, and then the light outlet of the second light emitting part and the light outlet of the first light emitting part are oppositely arranged, so that when the composite material needs to be cut, the composite material is arranged between the light outlet of the second light emitting part and the light outlet of the first light emitting part, and the composite material can be cut conveniently. The second light emitting part and the first light emitting part are correspondingly adjusted and controlled to execute matched cutting, that is, the corresponding positions of the two opposite sides of the composite material can be cut separately or simultaneously, then the problems that when one side of the composite material is cut through single-side laser, the opposite sides of the composite material become yellow, black, bubbles and the like can be solved, and therefore the yield is increased.

Description

technical field [0001] The present application relates to the field of cutting technology, and in particular, to a laser cutting device, equipment and method. Background technique [0002] At present, most of the products that require high-precision processing are processed by laser, such as steel cutting, plastic cutting, leather cutting, glass cutting, etc., and most of the above single-material cutting processes can be completed by mainstream single laser beam cutting. [0003] For multi-layered composite materials, the materials corresponding to different layers are different, and the properties of the materials corresponding to each layer are generally different, and a certain thermal effect will be generated during laser cutting. The heat will be transferred to the side opposite to the processing side, which will cause the material on the opposite side to produce unfavorable conditions such as discoloration (such as yellowing, blackening), air bubbles, etc., which will...

AI Technical Summary

Problems solved by technology

[0003] For composite materials with multi-layer structure, different layers correspond to different materials, and the properties of materials corresponding to each layer are generally different, and laser cutting will generate a certain amount of heat. Therefore, when cutting with traditional single-sided laser cutting technology, The heat will be transmitted to the side opposite to the processing side, resulting in abnormal color (such as yellowing, blackening), air bubbles and other adverse conditions on the material on the opposite side, affecting product quality

[0004] Therefore, the yield rate of existing laser cutting needs to be improved
