Optical film visual intelligent detection equipment

Abstract

Optical film visual intelligent detection equipment comprises a feeding unit, a detection unit and a collection unit; the feeding unit comprises a feeding module and a protection film uncovering mechanism, the protection film uncovering mechanism comprises an adhesive tape feeding module, an adhesive tape pressing and attaching module and a protection film uncovering module; the detection unit comprises a lighting module, a camera shooting module and an upper computer; the collection unit comprises a protection film attaching mechanism, a defective-product marking mechanism and a collection module, and the protection film attaching mechanism comprises a protection film feeding module and a protection film pressing and attaching module. The optical film visual intelligent detection equipment is mainly used for full-automatically detecting optical film products in a visual intelligent detection way to further screen out defected optical film products, and has the advantages of high detection efficiency, high detection reliability; meanwhile, because of relatively reasonable structure design, the advantages of compact structure, small occupied area and relatively low cost are achieved; above all, not only is the defect identification rate of the equipment to the optical film products high, but also false detection cannot occur, so that the quality control of the products is ensured.

Description

technical field [0001] The invention relates to a detection device, in particular to a visual intelligent detection device of an optical film, and the optical film includes a brightness enhancement film, a protective film, etc. used in a mobile phone or a tablet computer. Background technique [0002] With the continuous development and progress of science and technology, the market for electronic products, especially mobile intelligent terminal products, continues to expand, and a large demand for optical films has emerged as the times require. [0003] There are many kinds of optical film products, which are widely used in mobile intelligent terminal products, among which brightness enhancement film is a typical example. Brightness Enhancement Film (BEF, Brightness Enhancement Film) is a film or sheet used in TFT and LCD backlight modules to improve the luminous efficiency of the entire backlight system of electronic equipment. It is widely used in liquid crystal displays....

AI Technical Summary

Problems solved by technology

[0004] 1. Completely manual inspection, through the human eyes of the inspectors to observe the brightness enhancement film products, to find defective brightness enhancement films and eliminate them; this manual inspection method leads to high labor costs for enterprises, and the detection efficiency is not good; the actual In addition, human eye detection is also prone to fatigue and missed detection, so there is still a problem of low reliability, resulting in unstable product quality;

[0005] 2. Mechanical testing, which intends to replace manual testing with automated testing equipment; however, looking at the industry, there is no well-designed solution. Existing testing equipment or mechanisms are too complex, there are too many redundant structures, or the testing efficiency is not good. , low reliability; in addition, since the brightness enhancement film products are usually arranged on the belt-shaped base film at intervals during testing, and are covered by a belt-shaped protective film, when testing, the equipment often misses due to the cover of the protective film. Defects in the brightness enhancement film itself, sometimes mistakenly identify and eliminate defects on the protective film as defects of the brightness enhancement film, resulting in false detection and waste of products
