Device and method for processing light guide plate through high-efficiency parallel lasers

Abstract

The present invention proposes a device and method for high-efficiency laser parallel processing of light guide plates, including: a frame, a first processing arm, a second processing arm, a laser system, an adsorption system, and a laser head transmission system respectively arranged on the frame; The laser system includes a laser. The laser light emitted by the laser is divided into two parts after passing through the beam splitter. One part is finally focused by the laser head on the first processing arm through mirror reflection; the other part is finally focused by the laser head on the second processing arm through mirror reflection. Head focusing; the beneficial effects of the present invention: in the laser system, the laser beam is split by the convex lens, the utilization rate of the laser is improved, and the two processing arms process the light guide plate at the same time, which improves the processing efficiency of the light guide plate. double the device.

Description

technical field [0001] The invention relates to the field of high-end laser manufacturing equipment and advanced processing technology, in particular to an efficient laser parallel processing device and method for light guide plates. Background technique [0002] Liquid crystal display (LCD) has become the mainstream of flat panel display. As a green lighting method, LED backlight is gradually becoming the standard configuration of LCD. It is very important to convert the light source into uniform light output on the surface and to design and manufacture the light guide plate quickly and efficiently. [0003] Performance parameters such as brightness and uniformity of the backlight module directly affect the image quality of a liquid crystal display (LCD). Liquid crystal displays have more and more stringent requirements in terms of brightness and chromaticity, so the requirements for backlight modules are also getting higher and higher. Light-emitting diode (LED) is a sol...
