Problems solved by technology

[0003] Most manufacturers choose to scrap the usual polarizer film air marks (bubbles) or poor warping, or the process of changing the protective film. The disadvantage is that the cost of scrapping is high, and the loss when the protective film is changed increases, which invisibly increases production. cost

Abstract

The invention relates to a laminating mechanism for relaminating a polaroid protective film. The laminating mechanism comprises a protective film and polaroid body separating device, a protective film conveying device, a polaroid body conveying device and a protective film and polaroid body laminating device, a polaroid is stripped into a protective film and a polaroid body through the protective film and polaroid body separating device, the protective film is transmitted to the protective film and polaroid body attaching device through the protective film transmission device, and the polaroid body is transmitted to the protective film and polaroid body attaching device through the polaroid body transmission device. The protective film and the polaroid body are laminated into a polaroid through the protective film and polaroid body laminating device; the laminating mechanism can be used for re-laminating the defective polaroid into a new polaroid after the protective film is stripped, so that the scrapping is avoided, and the cost is reduced.

Description

technical field [0001] The invention relates to a laminating mechanism, in particular to a laminating mechanism for returning a protective film of a polarizer. Background technique [0002] With the development of polarizers and the further reduction of costs, display technology continues to seek innovation and development, display screens have brought convenience to people, medium and large sizes are a major direction of domestic production, and domestic production capacity continues to expand. The needs of the industry are constantly improving, and the industrial structure is oriented toward high output value, high utilization rate, low cost, convenient operation, and optimized performance to meet customer needs. [0003] Most manufacturers choose to scrap the usual polarizer film air marks (bubbles) or poor warping, or the process of changing the protective film. The disadvantage is that the cost of scrapping is high, and the loss when the protective film is changed incre...
