A kind of burnishing device for light guide plate twin polishing
Technical field:
The invention belongs to light guide plate technical field of processing equipment, are specifically related to a kind of throwing for light guide plate twin polishing
Electro-optical device.
Background technology:
With the development of liquid crystal industry, light guide plate has been widely used, and having become at present can not in liquid crystal module
The part lacked.The main function of light guide plate is:After being imported from side by LED light source, reflected by the printing net-point in later stage,
Light source is set to homogenize.In the process of light guide plate, end face needs to be processed by shot blasting, to reach surface best bright finish, comes
Reduce the loss of light transmission.So in process, the end face polishing treatment of light guide plate is extremely important, affects light guide plate
Quality affects the quality of entire liquid crystal module.
Currently, some small processing factories are processed by shot blasting the end face of light guide plate using the polissoir of hand-held, pacify
Full property is poor, and processing efficiency is low, and the factory of most of batch productions is then processed by shot blasting light guide plate using polishing machine, but
Be existing polishing machine at work, need to set corresponding positioning fixture on polishing machine for light guide plate, to throw with improving
The stability of light guide tabula rasa and safety, but when the existing positioning fixture for polishing machine positions light guide plate, hold
It is not firm easily to occur clamping, low so as to cause polishing machine processing efficiency, processing quality is poor, and safety cannot ensure, and existing
Positioning fixture can only carry out single-sided polishing to light guide plate, need to remove light guide plate from positioning fixture after the completion of single-sided polishing
Turn-over, then install to positioning fixture, realize the polishing treatment of another side;Realize that the twin polishing of light guide plate needs to dismantle peace repeatedly
Light guide plate is filled, it is not only troublesome, and also working efficiency is not also high.
Invention content:
For this purpose, technical problem to be solved by the present invention lies in be used for the positioning fixture of polishing machine in the prior art to leaded light
Board clamping is not firm, and processing quality is poor, and safety is low, and can only carry out single-sided polishing, two-sided to be required for needing repeatedly when polishing
Dismounting installation light guide plate, it is not only troublesome, and also working efficiency is not also high, to propose a kind of throwing for light guide plate twin polishing
Electro-optical device.

One end of the outside of connecting plate forms fixed block, and the fixed block is resisted against on the lateral wall of the connecting plate, the fixation
Block is hinged on by the second fastening bolt on the lateral wall of the connecting plate.
As a preferred embodiment of the above technical solution, the first screw hole is provided on the side wall of the selector bar, in the fixed link
It is provided with the second screw hole, first fastening bolt is screwed onto after passing through first screw hole in second screw hole.
As a preferred embodiment of the above technical solution, the fixed link and the selector bar height it is identical, the fixed link it is upper
End face is provided with the first telltale mark, and the upper and lower end face of the selector bar is respectively arranged with the second telltale mark, and described first is fixed
After position label and second telltale mark positioning, first screw hole and second screw hole are correspondingly arranged.
As a preferred embodiment of the above technical solution, the first position block on block connecting plate and the second position block are at least
It is a.
As a preferred embodiment of the above technical solution, first position block and second position block are rectangle gear
Block.
As a preferred embodiment of the above technical solution, add corresponding with the polishing disk is provided at the center of the processing platform
The length and width in work hole, the processing hole is respectively less than the spacing between two pieces of connecting plates being oppositely arranged.
The beneficial effects of the present invention are:It is kept off by the way that fixed link, selector bar and connecting plate is arranged by the first positioning
Block and the second position block and fastening bolt are clamped positioning to light guide plate, ensure that the stability and peace of light guide plate polishing
Quan Xing, processing quality is good, while being located above processing platform by selector bar, connecting plate, the first positioning baffle and the by overturning
The overturning of light guide plate can be realized in the entire clamping and positioning device that two positioning baffles are constituted, and it is guide-lighting need not to dismantle installation repeatedly
Plate, work efficiency is high;It can move up and down clamping and positioning device by the way that lifting cylinder is arranged on processing platform,
Polishing machine is facilitated to be polished.The present apparatus is simple in structure, easy to operate, practicability is good, safe.
