Automatic coating machine

Abstract

The invention discloses an automatic coating machine which comprises a work platform as well as a product conveying system, a coating system and a protection film conveying and recycling system which are arranged on the work platform, wherein the protection film conveying and recycling system comprises an adhesive tape conveying part and a protection film residue recovering part. When the machine runs, the product conveying system is used for automatically conveying a product and a protection film to a coating station, the coating system is used for cutting the protection film and applying the cut protection film to the surface of the product, production film residues generated during cutting of the production film are automatically recycled after the coating action is finished, and the product is automatically conveyed out, wherein the two-time rolling operation is performed to completely squeeze out air in the protection film to enable the protection film to completely cling to the product before the product is conveyed out. According to the automatic coating machine, the automatic coating operation is finished instead of a manual coating operation, the coating efficiency can be effectively improved, the manpower cost is reduced, the coating operation is simpler and easy, air bubbles in the protection film are squeezed out to enable the protection film to completely cling to the product, and the coating effect is ideal.

Description

technical field [0001] The invention relates to the technology in the field of automatic detection, in particular to an automatic film sticking machine. Background technique [0002] At present, the competition of consumer products in the electronics and electrical appliances industry is very fierce. In order to occupy the market and realize product value, the appearance of the product has become an important factor. Since the product shell parts may come into contact with external objects during production, processing and assembly, as well as product inspection and handling, it may cause slight scratches, scratches, dirt and other defects on the surface, which will affect the appearance quality of the product. Therefore, it has become a necessary link to protect the surface of the product shell parts, and the surface protection film is a commonly used protection process. [0003] At present, the industry basically uses manual sticking of protective film, and manual work ha...

AI Technical Summary

Problems solved by technology

[0003] At present, the industry basically uses manual sticking of protective film, and manual work has the following disadvantages: (1) low work efficiency; (2) poor positional accuracy of sticking protective film, which is difficult to guarantee for those with positional accuracy requirements; (3) high labor intensity , easy to fatigue the operator

[0004] However, some of the current market also adopts the technology of automatic protective film application. This technology adopts the technology of knife die punching and cutting first and then sticking. It is easy to warp; (2) the reliability is not good, there will be air bubbles between the protective film and the surface of the product, and 100% lamination cannot be achieved; (3) the release paper at the bottom of the protective film needs to be torn off to stick the film, which is difficult to achieve Automatic film tearing; (4) It is difficult to realize automatic recycling of the remaining material after punching the protective film with a knife die
