Laser processing device and method for multi-layer material

Abstract

The invention provides a laser processing device and method for a multi-layer material and belongs to laser processing materials. The laser processing device for the multi-layer material comprises a light source used for outgoing of laser beams and a multi-focal-point diffraction optical element; and the laser beams are separated through the multi-focal-point diffraction optical element to form a plurality of focusing light spots sequentially arranged in a spaced manner along the spreading path of the laser beams. The laser processing method for the multi-layer material includes the following step that the multi-focal-point diffraction optical element is used for separating the laser beams into the focusing light spots sequentially arranged in the spaced manner along the spreading direction of the laser beams. The focusing light spots are irradiated on the multi-layer material so that the focusing light spots can be located in a plurality of material layers of the multi-layer material. The processing method can fast and efficiently perform laser processing on the multi-layer material, and therefore a high-quality workpiece can be acquired, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of laser processing materials, in particular to a laser processing device and method for multilayer materials. Background technique [0002] Manufacturers of smartphones and other consumer electronics products continue to add features and complexity to consumer devices based on market needs, while striving to simplify the form factor and improve industrial design of consumer products. A key requirement in the process of upgrading, designing, or driving for products is to reduce the thickness of these devices while retaining or increasing their functionality. [0003] To achieve the aforementioned goal of reducing device size while maintaining or increasing the functionality of the device, it is common practice to laminate the device and functionality onto existing components, merging several functions into a single component. [0004] Glass touch panel stackups are representative of complex multilayer material stacku...

Problems solved by technology

However, the properties of different layers of materials are different, which can lead to problems during the cutting process, such as poor cut quality, irregular cut edges, large-scale or uncontrollable damage to different layers of material at the cut

Due to the particularity of the properties of various materials and the diversity of combinations of laminates between materials, the existing multi-layer material processing methods have greatly increased the difficulty of cutting and processing, which in turn makes the laminated laminated after cutting Product quality and production efficiency decline when materials
