Automatic film stripping equipment

Abstract

The invention discloses automatic film stripping equipment. The automatic film stripping equipment comprises a feeding mechanism, a first taking mechanism, a first delivery mechanism, a film stripping mechanism, a second delivery mechanism and a second taking mechanism, wherein the film stripping mechanism comprises a first film stripping mechanism and a second film stripping mechanism; the first film stripping mechanism comprises at least one first viscous coil unwinding mechanism and at least one first film collecting wheel; and the second film stripping mechanism comprises at least one second viscous coil unwinding mechanism and at least one second film collecting wheel. The automatic film stripping equipment further comprises a controller, and the feeding mechanism, the first taking mechanism, the first delivery mechanism, the first viscous coil unwinding mechanisms, the first film collecting wheels, the second viscous coil unwinding mechanisms, the second film collecting wheels, the second delivery mechanism and the second taking mechanism are electrically connected with the controller. The automatic film stripping equipment can automatically strip protective films on the upper surface and the lower surface of a product and orderly collect the stripped protective films to reduce environmental pollution; and the whole film stripping process is mechanically controlled fully automatically, the product rejection rate is low, and the automatic film stripping equipment is suitable for wide popularization.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a film tearing device for tearing off the protective film on the surface of electronic products such as mobile phone screens, displays, LED diffusion plates or LED light guide plates. Background technique [0002] In the last step of the production process of electronic products such as mobile phone screens, displays, LED diffusers or LED light guide plates, a protective film will be adhered to the upper and lower surfaces. Damage caused by collision and friction. When the product continues to operate downstream, the protective film on the upper and lower surfaces needs to be removed. [0003] Most of the existing film tearing methods are artificial tearing of the film, and the protective film adhered to the surface of the product is torn off manually, but the labor intensity of artificial tearing of the film is relatively high and the efficiency is low, which seri...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing film tearing methods are artificial tearing of the film, and the protective film adhered to the surface of the product is torn off manually, but the labor intensity of artificial tearing of the film is relatively high and the efficiency is low, which seriously affects the downstream production efficiency of the product; The tear film is easy to tear the protective film, which increases the scrap rate of the product, thereby increasing the production cost of the product

[0004] In addition, although some existing film tearing machines can save manpower and labor, improve tearing efficiency, and will not tear the protective film, the effect of tearing the film is still not satisfactory: for example, film tearing methods, film tearing devices and film tearing methods The device (CN102064087A) discloses a method of using a spatula to remove the film on the surface of a product. Higher accuracy is required when using the spatula to remove the film. If the control is not good, the spatula will be in direct contact with the product surface, resulting in product damage. Damage; Another example, a film tearing machine and film tearing method (CN102896876A) discloses a method of using a grinding wheel to remove the film on the surface of the product. The film at the edge of the flat plate is brought up by the rotation of the grinding wheel, so that the film and the product surface There is a large gap between them, and then a special clamp is inserted into the gap to tear off the film

However, the grinding wheel may come into contact with the surface of the product during the process of rotating the film, thus scratching the edge of the product and causing the product to be scrapped
