Optical film intelligent vision detection and defective product removal equipment

Abstract

Optical film intelligent vision detection and defective product removal equipment comprises a feed unit, a detection unit, a defective product removal unit and a receiving unit, wherein the feed unit comprises a feed module and a protective film uncovering mechanism, and the protective film uncovering mechanism comprises an adhesive tape feed module, an adhesive tape pressing-sticking module and a protective film uncovering module; the detection unit comprises an illumination module, a camera shooting module and an upper computer; the defective product removal unit comprises a material tape positioning mechanism, a material tape shearing mechanism and a material tape splicing mechanism; the receiving unit comprises a protective film sticking mechanism and a receiving module; and the protective film sticking mechanism comprises a protective film feed module and a protective film pressing-sticking module. Optical film products are fully automatically detected mainly in a manner of intelligent vision detection, and then defective optical film products are identified and removed. The optical film intelligent vision detection and defective product removal equipment has the advantages of being high in detection efficiency and detection reliability. Meanwhile, structural design is reasonable, the defect recognition rate of the optical film products is high, false detection will not occur, and quality control over the products is guaranteed.

Description

technical field [0001] The invention relates to a detection device, in particular to a visual intelligent detection and defective product rejection device of an optical film. 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...

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
