Fixture for polishing side edges of circular light guide plates

Abstract

The invention discloses a fixture for polishing side edges of circular light guide plates. The fixture comprises a fixing frame, square locating plates, circular clamping plates, a rotating shaft, a locating plate, a fulcrum, a lifting cylinder and a locking bolt. The fixture can locate a plurality of the light guide plates and can adjust positions of circle centers of the circular light guide plates conveniently to realize that the circle centers of the circular light guide plates and the rotating central axis of a polishing device are in the same straight line; moreover, the fixture can clamp the light guide plates which are adjusted in position and facilitates side edge polishing of the circular light guide plates accordingly. The fixture is simple in structure, convenient to operate, high in polishing efficiency and good in polishing effect.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of light guide plate processing equipment, and in particular relates to a fixture for polishing the side of a circular 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. After the light guide plate is processed, it generally needs to be polished. The common polishing is generally the front and back of the light guide plate. However, after the light guide plate is cut and cut, the side of the light guide plate also needs to be polished. [0005] The side of the light guide plate is generally polished manually, that is, the hand-held light ...

AI Technical Summary

Problems solved by technology

[0005] The side of the light guide plate is generally polished manually, that is, the hand-held light guide plate is used to work on the polishing disc, but its safety is poor. At the same time, because the thickness of the light guide plate itself is relatively thin, hand-held polishing is likely to cause deformation of the side of the light guide plate and affect the light guide plate. The quality of the circular light guide plate, especially for the circular light guide plate, is more difficult to polish the side of the circular light guide plate, and it is more prone to safety accidents or quality problems
