Embodiment Construction

[0022] The present invention uses high-speed optical scanning galvanometer, CO 2 Lasers and a motion processing platform enable the etching process. In this process, the optical scanning device drives the reflective lens (very light, about 100 grams), and the laser is reflected by the lens to form a laser movement, so the movement speed can be greatly improved, which is many times higher than the overall speed of the traditional movement platform. This process method does not use non-corrosive acid for processing, has no toxicity caused by ink, can reach 100% yield, and has high processing efficiency (1 minute / piece).

[0023] Such as figure 1 As shown, the device used to process large-format light guide plates, including CO 2 Laser 1, multi-dimensional motion scanning galvanometer 2 and motion working platform 3, CO 2 Laser 1 is CO with a wavelength of 10.6 μm 2 laser, CO 2 The output end of the laser 1 is provided with a multi-dimensional motion scanning galvanometer 2,...

Abstract

The invention relates to a device and a method for processing a large-breadth light guide plate. In the device, an output end of a CO2 laser is provided with a multi-dimensional motion scanning galvanometer; the multi-dimensional motion scanning galvanometer is opposite to a motion processing platform; laser light emitted by the CO2 laser reaches the motion processing platform after passing through the multi-dimensional motion scanning galvanometer; CO2 laser light acts on a processed material on the motion processing platform; a micro pit of 100 to 1,000 micrometers is formed on the processed material after the action of the laser light; 1,000 to 2,000 micro pits are formed per second at a frequency of 1 to 20KHz by controlling a laser switch at a high speed; an optical scanning area is formed by the laser light under the rotation of laser reflector plates driven by the multi-dimensional motion scanning galvanometer; the size of the scanning area depends on the area scanned by the multi-dimensional motion scanning galvanometer; and a laser processing area is increased by driving the light guide plate to move through the motion processing platform, so that the large-breadth light guide plates meeting various application requirements are processed. By the device and the method, required micro pits with different shapes are easily processed, a processed product cannot be deformed, and the finished product rate is obviously improved.

Description

technical field [0001] The invention relates to a device and method for processing a large-format light guide plate. Background technique [0002] At present, there are two processing methods for large-format light guide plates: [0003] 1) Printing process method: first produce a film according to the optical requirements, then transfer it to a screen template, clean the screen board (because the screen board is corroded by acid, so the acid should be cleaned), Then put the screen board in alignment and place it on the working board, scrape a special ink on the screen board, and finally dry it in an oven. Therefore, there are many processes, corrosive acid is produced, the ink is poisonous and polluted, the starting point of manual printing and the place where it is lifted are more ink, which will affect the quality of light guide, and the baking process is easy to deform the product, resulting in low yield. (30%), general efficiency (2 minutes / tablet); [0004] 2) Tradi...
