TECHNICAL FIELD
[0001] The present application belongs to the technical field of laser processing, and particularly relates to a roller surface texture processing method and device with multiple mirror heads. BACKGROUND
[0002] The microstructure texture of the roller surface can provide the rolled plate with the effects of beauty, anti-skid, anti-fingerprint, anti-glare, micro-lubrication and drag reduction, or realize specific acousto-optic and electromagnetic functions.
[0003] At present, the high-precision microstructure texture on the surface of photovoltaic glass rollers and optical lens rollers is mainly manufactured by traditional machining methods such as turning and knurling. The main problems of these methods are as follows: 1) tool wear exists, which leads to poor consistency of the texture in the machining process and increases the cost and time of tool changing and tool setting; 2) the process flexibility is low, and the texture needs to be re-customized when the texture is changed; 3) high-hardness roller base materials cannot be machined, which leads to short service life of the roller texture and frequent rework.
[0004] Although there are many process technologies such as shot blasting, electric spark, and laser texturing on the surface of the roller to realize the machining of the surface microstructure (surface texturing), these processes cannot realize the machining of functional microstructure texture with complex morphology and geometric precision requirements, and the efficiency is low or even cannot be realized when used for deep texture machining. Therefore, these processes mainly provide texture for appearance effect and friction performance modification, and cannot realize complex texture with specific acousto-optic and electromagnetic functions. Therefore, these process technologies are mainly used for the surface texture machining of the rollers for rolling steel plates, and cannot be used for the surface texture machining of the rollers for photovoltaic glass rollers and optical lens rollers which rely on large-depth and high-precision surface microstructure texture to realize specific optical performance.
