Automatic processing equipment for microstructures of light guide plate

Abstract

The invention relates to the technical field of production of plastic products, and particularly discloses automatic processing equipment for microstructures of a light guide plate. The automatic processing equipment comprises a first rack, a second rack, a feeding device, a clamping mechanism, a positioning mechanism, a processing mechanism and a control cabinet, wherein the first rack and the second rack are detachably connected; the feeding device is arranged on the first rack, a door-shaped support frame is arranged on a work panel at the top of the second rack, a worktable is arranged in the support frame and arranged on the work panel at the top of the second rack through support columns, the clamping mechanism and the positioning mechanism are arranged on the support frame respectively, and the processing mechanism is arranged on the work panel at the top of the second rack. The automatic processing equipment for the microstructures of the light guide plate has the advantages that the structure is simple, the cost is low, the microstructures with consistent size can be processed at the edge of one side of the light guide plate while the processing is not influenced by the thickness and size of the light guide plate, the product processing accuracy is guaranteed, and the production efficiency can be increased.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to an automatic processing equipment for the microstructure of a light guide plate. Background technique [0002] With the development of science and technology, liquid crystal displays have been widely used in various electronic devices that need to be displayed. Since the liquid crystal material itself does not have special lighting effects, it is necessary to use a special backlight module to provide the LCD panel with backlight for displaying images. source. Because the size of the light source of the backlight module is small and the light is too concentrated, the light emitted by the light source of the backlight module is too concentrated after entering the light guide plate. Although it is scattered by the dots on the bottom of the light guide plate, it is still easy to produce bright and dark areas. Bright lines and other issues. Therefore, in the prior...

Problems solved by technology

[0004] (1) Machining with a disk milling cutter. This processing method is mainly to stack multiple light guide plates together and fix them on the station to process the microstructure of the desired shape through a disk milling cutter. This forming method is easy The depth of the microstructure after molding is inconsistent, the yield rate is low, and the light source is scattered unevenly

[0005] (2) Injection molding. The advantages of this molding method are: good stability, continuous production, high yield, good processing consistency, and long mold life; the disadvantages are: long mold production cycle, high mold cost, and process requirements. High, the injection stress will affect the flatness of the product, and the production equipment using injection molding is limited by the process during production, it is impossible to make large-sized products, and it is impossible to make ultra-thin products
