Feeding unit of optical film vision intelligent detection device

Abstract

A feeding unit of an optical film vision intelligent detection device comprises a feeding module and a protection film tearing mechanism; the protection film tearing mechanism comprises an adhesive tape feeding module, an adhesive tape pressing and attaching module and a protection film tearing module; a strip position adjusting system is further included and comprises a strip deviation correcting mechanism and a strip tension adjusting mechanism. Compared with the prior art, automatic feeding of an optical film strip and automatic tearing of the protection film can be achieved, and therefore through the vision intelligent detection device, an optical film product can be detected in a full-automatic manner, and a defective optical film product can be distinguished. Due to the fact that the structural design is reasonable, the beneficial effects of being compact in structure and small in occupied area are achieved; most importantly, through the innovation design, the creative optical detection manner is achieved, the defect recognizing rate of the optical film product is high, meanwhile, wrong detection is avoided, and the quality control of the products can be ensured.

Description

technical field [0001] The invention relates to a detection device, in particular to a feeding unit in 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...

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
