Adhesive film feeding mechanism

Abstract

The invention discloses an adhesive film feeding mechanism. The adhesive film feeding mechanism comprises a conveying module, a feeding module and a receiving module; the conveying module comprises a conveying belt and a control unit; the feeding module comprises an adhesive film support and a guide wheel set; the receiving module comprises an adhesive film separating structure and an adhesive film guide structure; and during feeding, an adhesive film is attached to the conveying belt and is driven through motion of the conveying belt to be fed, and through motion between the modules and design changes of allocation relations, the control complexity of the feeding mechanism is reduced. According to the adhesive film feeding mechanism, a guide wheel set can be used for extruding bubbles generated during adhesive film attaching out, a leveling wheel can be used in a matched manner to flatly attach the adhesive film to the conveying belt, and therefore the cutting quality of the adhesive film is maintained.

Description

Technical field [0001] The present invention relates to automatic feeding technology, in particular to a film feeding mechanism. Background technique [0002] A layer of protective film can be attached to the surface of touch information products to achieve the purpose of dustproof and antifouling. With the market expansion of touch information products such as smart phones and tablet computers, the demand for protective film is rapidly increasing . [0003] However, when the traditional adhesive film is laid on the cutting platform, wrinkles or bubbles are prone to be generated, and it needs to be flattened or reformed manually, and the production efficiency is low. Moreover, with the market competitiveness of information products, the speed of product replacement becomes faster, and the size of consumables such as protective film must also be customized. Therefore, the production of film cutting must meet the production of batches of products in a short time to meet the needs o...

Problems solved by technology

[0004] However, most of the common feeding mechanisms at present adopt active drive, so that the film with extremely thin thickness is prone to warping and deformation after passing through the feeding roller.

Under the demand of customization, the feeding mechanism must adapt to adjust the corresponding conveying rate according to different film materials, thus increasing the adjustment time of program parameters and increasing production costs

[0005] In addition, the structure of the existing feeding mechanism is complex and requires multiple driving sources to cooperate with each other. It is inevitable that the tension of the material will change during the film transportation, resulting in inaccurate product dimensions or cutting of the film material during the cutting process. cutting loss
