Description

Technical Field

[0001] This utility model relates to the technical field of light guide plate assembly equipment, and in particular to a light guide plate assembly equipment. Background Technology

[0002] A light guide plate is made of optical-grade acrylic / PC sheet. High-tech materials with extremely high refractive index and no light absorption are used to print light guide points on the bottom surface of the optical-grade acrylic sheet using laser engraving, V-shaped cross-grid engraving, and UV screen printing technology. The optical-grade acrylic sheet absorbs light emitted from a lamp and allows it to remain on its surface. When light hits each light guide point, the reflected light diffuses in all directions, breaking the reflection condition and emitting light from the front of the light guide plate. Through various density and size light guide points, the light guide plate can emit light uniformly. The purpose of the reflective sheet is to reflect the light exposed on the bottom surface back into the light guide plate, thereby improving light utilization efficiency. Under the same area and brightness conditions, it has high luminous efficiency and low power consumption. Single-sided microstructure array light guide plates are generally manufactured using an extrusion molding process.

[0003] Before assembly, existing light guide plates may be contaminated with dust. Failure to remove this dust will affect subsequent processing and assembly. Therefore, it is necessary to clean the light guide plate using a dust removal and cleaning machine. However, the dust removal and cleaning machine transports the light guide plate via a conveyor belt, which causes a portion of one side of the light guide plate to be blocked by the conveyor belt, resulting in some dust residue.

[0004] Therefore, there is an urgent need to provide a light guide plate assembly device to solve the above problems. Utility Model Content

[0013] The present invention is further configured such that: a second slider is slidably installed inside the lifting slide rail, one end of the second slider is fixedly connected to a second conveyor frame, and the second conveyor frame is fixedly connected to one end of a reciprocating rack on the other side.

[0014] Through the above technical solution, the reciprocating rack on the other side drives the second conveyor frame to reciprocate up and down on the lifting slide rail via the second slider.

[0018] Through the above technical solution, the second motor drives the second conveyor belt and the second driven pulley to rotate via the second driving pulley.
