Laser parallel processing device and processing method for array air holes of leather product

Abstract

The invention discloses a laser parallel processing device and processing method for array air holes of a leather product. The laser parallel processing device comprises a laser system, an optical light guide system,an X-Y two-dimensional honeycomb adsorption platform system and a computer control system, wherein an optical path outlet of the laser system is opposite to an optical path inlet of the optical light guide system, and an optical path outlet of the optical light guide system is opposite to a working area of the X-Y two-dimensional honeycomb adsorption platform system; the optical light guide system involves a pneumatic optical shutter, a quarter slide, a reflector, an adjustable beam expander lens, an adjustable diaphragm, a dichroic mirror, a laser beam splitting unit and a scanning galvanometer; and a laser beam optical path output by the laser system sequentially passes through the pneumatic optical shutter, the quarter slide, the reflector, the adjustable beam expander lens, the adjustable diaphragm, a surface of the dichroic mirror, the laser beam splitting unit, the scanning galvanometer, and a to-be-processed leather surface, and the other surface of the dichroicmirror is provided with a red light unit.

Description

technical field [0001] The disclosure relates to the technical field of laser processing of leather products, in particular to a laser parallel processing device and processing method for array air holes of leather products. Background technique [0002] The advantages of leather products such as beautiful color, softness, comfort, and durability make it widely used, such as leather clothes, leather pants, leather shoes on our feet, and various leather sofas, car leather cushions, leather bags and handbags, etc. , a wide variety can be seen everywhere. Natural leather (genuine leather) is processed from animal skin, which is characterized by softness, wear resistance, high strength, pores on the surface, and good air permeability (for example, the pores on the surface of cowhide leather are small, round, and evenly distributed), but Resources are limited and expensive. Artificial leather (synthetic leather, mainly made of PVC / PU) has the characteristics of low cost and wid...

AI Technical Summary

Problems solved by technology

At present, laser leather drilling in the market is dominated by single-beam laser processing. Therefore, in the processing of large-format array micro-holes, there is still a gap between leather laser drilling and traditional mechanical punching in terms of drilling efficiency.

In addition, the laser energy required for single-beam leather drilling is very small, and the performance of current high-power lasers cannot be fully utilized.
