Problems solved by technology
[0007] For this reason, the technical problem to be solved by the present invention is that the positioning fixture used for the polishing machine in the prior art is not reliable for clamping the light guide plate, the processing quality is poor, the safety is low, and it can only be polished on one side, and both sides need to be polished. When polishing, it is necessary to repeatedly disassemble and install the light guide plate, which is not only troublesome, but also the work efficiency is not high, so a polishing device for double-sided polishing of the light guide plate is proposed

The invention discloses a polishing device for double-side polishing of a light guide plate. The polishing device comprises a base, a polishing machine, a processing platform, a lifting air cylinder, a fixed rod, a transfer rod and a connecting plate. The polishing device is characterized in that by arranging the fixed rod, the transfer rod and the connecting plate, the light guide plate is clamped and positioned by a first positioning retaining block, a second positioning retaining block and a tightening bolt, so as to guarantee the polishing stability and safety of the light guide plate, and the good processing quality; by turning the whole clamping and positioning device consisting of the transfer rod, the connecting plate, a first positioning retaining plate and a second positioning retaining plate above the processing platform, the light guide plate can be turned over, the repeated detachment and installation of the light guide plate can be avoided, and the working efficiency is high; by arranging the lifting air cylinder on the processing platform, the clamping and positioning device can be vertically moved, so as to facilitate the polishing machine to polish. The polishing device has the advantages that the structure is simple, the operation is convenient, the practicality is good, and the safety is high.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of light guide plate processing equipment, and in particular relates to a polishing device for double-sided polishing of a light guide plate. [0003] Background technique: [0004] With the development of the liquid crystal industry, the light guide plate has been widely used and has become an indispensable part of the liquid crystal module. The main function of the light guide plate is: after the LED light source is introduced from the side, it will be reflected by the printing dots in the later stage to make the light source uniform. During the processing of the light guide plate, its end face needs to be polished to achieve a high surface finish and reduce the loss of light transmission. Therefore, in the processing process, the end surface polishing treatment of the light guide plate is very important, which affects the quality of the light guide plate and the quality of the entire liquid crysta...
