Aiming at the following problems, low efficiency of manual film, easy to produce bubbles and irregular, the small semi-automatic pasting machine is inconvenient, the large automatic pasting machine is expensive, a new automatic film pasting machine for mobile phone is put forward. The automatic film pasting machine is mainly composed of clamping, driving, cleaning, positioning and foil, it can remove implementation the functions of mobile phone screen cleaning, remove protective layer, automatically align the mobile phone screen and film. The power system is driven by a stepping motor, and the automatic control of the stepping motor is realized by AT89C51 single chip. The driving circuit of the stepping motor is composed of ULN2003. The display screen selects 8*8 LED display screen, and gives the display control circuit based on 51 single chip microcomputer. The result shows that the automatic film pasting machine achieves the preset functional requirements, the structure is simple, and the film holding efficiency is improved.
