The utility model discloses simple structure, infrared induction device install on printing jig light guide plate standing groove one side, because the printing light guide plate material is PMMA, one side is provided with the side card, sets for standard printing opacity distance during the use, and infrared ray printing opacity distance when infrared induction device surpasss standard printing opacity apart from the alarm and does not report to the police, is less than standard printing opacity apart from the alarm and reports to the police, explains that the light guide plate is turned over. The utility model can detect the light guide plate with reverse printing before printing, reduce the product damage rate and effectively avoid product scrapping; and the workload of inspectors can be effectively reduced.
Description
Technical Field
The utility model belongs to the technical field of the light guide plate printing, especially, relate to a prevent anti-detection device of light guide plate seal.
Background
The light guide plate (light guide plate) is made of optical acrylic/PC plate, and then high-tech material with high refractive index and no light absorption is used to print light guide points on the bottom surface of the optical acrylic plate by laser engraving, V-shaped cross grid engraving and UV screen printing technology.
Nowadays, the liquid crystal industry is competitive, and the manufacturing method of the light guide plate mainly includes printing type, carving type (machining and laser carving), etching type, injection molding type and the like, wherein the printing type has the advantages of low cost, high printing efficiency, relatively simple process control and the like, so that the light guide plate becomes a widely used mode in recent years.
The condition of printing the contrary often can appear in present printing formula light guide plate in the manufacture process, mainly because tearing membrane personnel and printing personnel put the contrary and lead to, and the rethread optometry inspection personnel detect.
Therefore, it is an effort of those skilled in the art to solve the above technical problems without affecting the quality of the product.
Disclosure of Invention
The to-be-solved problem of the utility model is to provide a simple structure reduces inspection personnel work load, lowers the detection device that prevents that light guide plate seal is anti-reversed of product system loss rate.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a prevent detection device that light guide plate seal is anti-inverted, includes printing jig, the last light guide plate standing groove that is provided with of printing jig, light guide plate standing groove one side is provided with infrared induction system, and this light guide plate standing groove top is provided with the half tone, the half tone top is provided with ink scraping knife and ink returning knife.
The infrared sensing device is connected with the alarm through the processor.
The light guide plate is placed in the light guide plate placing groove, and a side sticker is arranged on one side of the light guide plate.
The light guide plate is made of PMMA.
Due to the adoption of the technical scheme, the utility model discloses simple structure, infrared induction device installs light guide plate standing groove one side on the printing jig, because the printing light guide plate material is PMMA, and one side is provided with the side card (PMMA is transparent light-permeable, and the side is pasted nontransparent), sets for standard printing opacity distance during the use, and infrared ray printing opacity distance when infrared induction device surpasss standard printing opacity distance alarm and does not report to the police, is less than standard printing opacity distance alarm and reports to the police, explains that the light guide plate is turned over.
The utility model can detect the light guide plate with reverse printing before printing, reduce the product damage rate and effectively avoid product scrapping; and the workload of inspectors can be effectively reduced.
The utility model has the advantages that: the device has the advantages of simple structure, reduction of workload of inspectors and reduction of product damage rate.
