Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone film pasting, and specifically to an automatic mobile phone film pasting device. Background Art

[0002] For mobile phone cases with relatively high requirements on appearance, such as high-gloss appearance, it is easy to scratch the appearance of the mobile phone case during the processing and assembly of the mobile phone case, thereby affecting the appearance quality of the product. Therefore, it is necessary to affix a protective film to the appearance of the mobile phone case, thereby effectively protecting the appearance of the mobile phone case from scratches.

[0003] The existing film pasting process is to manually paste the protective film on the appearance surface. Due to the deviation of manual operation, the width of the protective film will be greater than the width of the appearance surface, so as to ensure that the protective film completely covers the appearance surface. At the same time, it will also cause part of the protective film to overflow the appearance surface. These overflowing protective films will inevitably interfere with other areas of the mobile phone case, thereby causing some auxiliary materials and accessories to be unable to be effectively pasted and assembled, such as the pasting of TP adhesive and the assembly of the touch screen. In this way, the overflowing protective film needs to be cut off, thereby increasing the cutting process, which not only increases the labor intensity and reduces the production efficiency, but also increases the risk of scratching the appearance surface, resulting in an increase in the product defect rate.

[0004] In order to solve the above problems, a Chinese patent with announcement number CN204871722U discloses a semi-automatic mobile phone film pasting device, which includes a bracket, the bracket is provided with a material roller and a rotating member that can rotate relative to the bracket, the material roller is fixed with a protective film roll, the rotating member is fixed with a product to be pasted with film, and a positioning guide member for positioning and guiding the protective film stretched out from the protective film roll is provided between the material roller and the rotating member. The semi-automatic mobile phone film pasting device fixes the protective film roll to the material roller and the product to be pasted with film to the rotating member. Since the material roller and the rotating member can rotate relative to the bracket, the protective film roll can be stretched out into a strip of protective film, and the rotating member can drive the product to be pasted with film to rotate. By rotating the rotating member, the protective film is quickly pasted on the surrounding appearance surfaces of the product to be pasted with film, thereby improving the film pasting efficiency, and before the protective film is pasted on the appearance surface, the positioning guide member guides and positions the movement of the protective film, effectively preventing the deflection of the protective film, thereby improving the film pasting accuracy, and thus improving the yield rate of the pasted mobile phone shell product. It can be seen from this that the semi-automatic mobile phone film pasting device can only apply film to the surrounding exterior surfaces of the product to be pasted, and there are limitations on the film pasting on the front of the mobile phone. At the same time, the film pasting is carried out by manually controlling the rotation of the rotating part, and the stability of the manual rotation control speed is not easy to guarantee. Therefore, the efficiency and product yield of the semi-automatic pasting device need to be improved. Summary of the invention
