Description
Technical field
The present invention relates to light guide plate die cutting techniques fields, in particular to a kind of light guide plate punching tool and punching side
Method.
Background technique
Light guide plate is the significant components in backlight module, and main function is the transmission for guiding the light beam issued from light source
Point light source or linear light source are converted into area source and projected again by direction.It is guide-lighting hardened as light guide plate application market is more and more extensive
Structure is more and more finer, and fabrication cycle requirement is shorter and shorter, and the degree of automation requires higher and higher.
Light guide plate in process of production, needs to separate the mouth of a river and waste material by punching.Fig. 2 is the punching of the prior art
The schematic diagram of method, by upper slitter 1 with cut 7 relative movements light guide plate 5 be punched out, wherein it is flat for cutting 7 blade
Face plays a supportive role, and the blade of upper slitter 1 is acute angle.This method for die cutting is easy to make the discontinuity of light guide plate 5, causes to cut
Dipped ring is whole, and the light guide plate 5 after punching, which also needs further to polish, just can be used, and increase production cost, reduces production effect
Rate and product quality.
Summary of the invention
The purpose of the present invention is to provide a kind of light guide plate punching tool and method for die cutting, and the light guide plate section after punching is flat
Whole degree is high, without further polishing processing.
One end of a kind of light guide plate punching tool, including cutter body, the cutter body is equipped with blade, and feature exists
In the blade is arc.
Preferably, the radian of the blade is 0.1-0.15.
Preferably, the cutter body and blade are respectively provided with the first joint face and the second joint face, cutter body and knife
First joint face of sword is concordant, and the second joint face is to the first inclined inclined-plane in joint face direction.
Preferably, first joint face and the second joint face angle are 10-15 degree.
Preferably, the blade is with cutter body junction with a thickness of 1-5 millimeters.
The present invention also provides a kind of light guide plate method for die cutting, are punched out, are specifically included using above-mentioned punching tool
Following steps:
A. light guide plate is placed on the carrying platform and is positioned；
B. by the blade of punching tool towards light guide plate to be punched, wherein the first joint face connects towards light guide plate side, second
Junction is towards the mouth of a river and waste material side；
C. punching tool is driven to be punched out from top to bottom by servo motor；
The pulse frequency control of servo motor is 1000-3000, moment of torsion control 14N when being D. punched；
E. after completing punching, punching tool resets, and the light guide plate after cutting is taken out.
Further, the Rockwell hardness of the carrying platform is 90-120.
Further, the carrying platform is POM material.
Compared with prior art, the beneficial effects of the present invention are: knife-edge becomes arc, and radian is arranged in 0.1-0.15
Between, when being punched light guide plate, make light guide plate uniform force, the flatness of notch can be effectively improved, is punched the light guide plate of completion
Without processing of further polishing, and dust and clast will not be generated in blanking process, be not necessarily to clear up the table of light guide plate after punching
Face avoids the production stage of polishing and cleaning, improves production efficiency, save while improving the quality of product
Production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of light guide plate punching tool of the invention.
Fig. 2 is the schematic diagram of the method for die cutting of the prior art.
Fig. 3 is the schematic diagram of light guide plate method for die cutting of the invention.
