Auxiliary jig for polishing of side of light guide plate

Abstract

The invention discloses an auxiliary jig for polishing of side of a light guide plate. The jig comprises a rear clamping plate, a plurality of insertion plates are fixed to the two sides of the front end face of the rear clamping plate, the front ends of the insertion plates penetrate through a front clamping plate to be fixed to a positioning plate, and a plurality of fastening bolts are connected with the positioning plate through threads; the two side edges of the rear clamping plates are fixedly provided with vertical racks, the rack on one side of the rear clamping plate is meshed with a driving gear and a driven gear, the rack on the other side of the rear clamping plate is meshed with a driven gear, the driven gears and the driving gear are fixed to hinge shafts in an inserted and sleeved mode, the two ends of each hinge shaft are hinged to side plates respectively, the upper ends of the side plates are fixed to connection blocks, the lower ends of the side plates are fixed to connection bases, and the bottom ends of the connection bases are fixedly connected with magnet suction cups; one end of the portion, on the driving gear, of the corresponding hinge shaft is fixedly connected with a rocker. The jig is simple in structure, assists a manual polishing light guide plate in use, brings convenience to manual polishing, and can effectively improve polishing safety.

Description

[0001] Technical field: [0002] The invention relates to the technical field of light guide plate processing equipment, and more specifically relates to an auxiliary jig for polishing the side 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. 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. Manual polishing, that is, holding the light guide plate to work on the polishing disc, but its safety...

Problems solved by technology

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. Manual polishing, that is, holding the light guide plate 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 thin, hand-held polishing is easy to cause deformation of the side of the light guide plate, which affects the quality of the light guide plate
