An enveloping UV laser marking machine that is convenient for marking flexible PCB boards

Abstract

The present invention relates to the technical field of laser marking machines, in particular to an enveloping ultraviolet laser marking machine that is convenient for marking flexible PCB boards, including a supporting structure, which is provided with a shielding device for shielding workpieces. Disassemble the connected protective cover, the inside of the support structure is provided with a second adjustment structure for adjusting the position of the laser marking head, and the support structure is provided with a linkage structure for adjusting the position of the second adjustment structure, the The linkage structure drives the second adjustment structure and the conveying structure to operate synchronously. The supporting structure is provided with a conveying structure for conveying the flexible PCB board. The supporting structure is provided with a first regulating structure for adjusting the position of the guiding structure. The conveying structure The structure cooperates with the guiding structure to position and transport the flexible PCB board, which is convenient for positioning and transporting flexible PCB boards of different thicknesses and sizes, thereby greatly improving the efficiency and quality of marking.

Description

technical field [0001] The invention relates to the technical field of laser marking machines, in particular to an enveloping ultraviolet laser marking machine which facilitates marking of flexible PCB boards. Background technique [0002] High-energy ultraviolet photons directly destroy the molecular bonds on the surface of many non-metallic materials, so that the molecules are separated from the object. This method does not generate high heat. The ultraviolet laser focus spot is extremely small, and the processing has almost no thermal influence, so it is called cold processing. , so it is suitable for ultra-fine marking and engraving of special materials, the ultraviolet laser focus spot is extremely small, and the processing has almost no thermal influence, so it is called cold processing, so it is suitable for ultra-fine marking and engraving of special materials, mainly used for ultra-fine High-end processing market, cosmetics, pharmaceuticals, food and other polymer m...

Problems solved by technology

[0003] However, most of the traditional enveloping UV laser marking machines set a fixed structure on the carrier table to fix the marking workpiece or directly place the marking workpiece on the carrier table. The flexible PCB board on the bearing table may be bent due to deformation, which affects the quality of marking. The stability of marking is poor, and it is not easy to take after marking. During the marking process, the workpiece needs to be reciprocally set on the UV marking head. At the bottom, the operation flexibility is poor. Most of the surrounding baffles that block ultraviolet rays are fixed, which are easy to block during inspection and maintenance, affecting the efficiency and quality of inspection and maintenance
