Problems solved by technology

[0003] The existing laser processing equipment for the light guide plate directly sucks away the impurities during dust removal, but this will generate negative pressure. Because the light guide plate is soft, the negative pressure will cause the light guide plate to deform, such as arching, etc. The deformation of the light guide plate will cause Laser refraction affects the accuracy of laser processing

Embodiment

[0048] First place the light guide plate at the cutting station 11, then the laser generator 41 generates a laser beam, after the beam expander 42 enlarges the laser beam spot and optimizes the quality of the laser beam, then passes through the beam splitter Mirror 43, so that the laser beam is divided into multiple laser beams, and then irradiated onto the light guide plate through the focusing of the focusing mirror 44, and then the driving device can drive the moving plate 45 to move, so that the beam splitting mirror 43 Move with the focusing mirror 44 to complete the cutting of the light guide plate.

[0049] And in the whole cutting process, the blowing device blows synchronously, and the flowing gas enters the air inlet 31, then passes through the drying box 32 for drying, and finally blows out from the blowing part 33, so that the guide The dust and impurities on the light board are blown, so that the dust and impurities pass through the dust suction member 23 under th...

Abstract

The invention relates to the technical field of light guide plate machining, in particular to laser machining equipment for a light guide plate. The laser machining equipment for the light guide platecomprises a rack, a dust suction mechanism, a blowing mechanism and a laser generating mechanism; the dust suction mechanism comprises an air outlet, a filtering box and a dust suction part; the blowing mechanism comprises an air inlet, a drying box and a blowing part; and the laser generating mechanism is used for generating laser light to cut the light guide plate. According to the laser machining equipment for the light guide plate, the blowing mechanism and the dust removing mechanism are arranged, blowing can be achieved while dust suction is conducted, generation of negative pressure isprevented, and the laser machining precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of light guide plate processing, in particular to laser processing equipment for light guide plates. Background technique [0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then high-tech materials with high reflectivity and non-absorbing light are used. Laser engraving, V-shaped cross grid engraving, and UV screen printing technology are used on the bottom surface of the optical-grade acrylic sheet Print light guide dots. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. The purpose of the r...
