Mobile phone vacuum film pasting machine with air convection for preventing indentations

Abstract

The invention discloses a mobile phone vacuum film pasting machine with air convection for preventing indentations. The machine comprises a worktable, a stand column, a shelf, a moving module, a filmsucking plate and a controller. The machine has the following beneficial effects: under negative-pressure effect of air currents, a support fixing structure is provided for negative-pressure absorption of mobile phones placed on the surface thereof, so that the slight slippage phenomenon caused by coaction between instant downward pressure of the external force effect and the shell surface smoothness of the mobile phones during film pasting and pressing is prevented; and the air convection is generated for the upper parts of the surfaces pasted with films of the mobile phones placed on a panelby using cooperation between an indentation preventing mechanism and an air sliding structure, so that the falling of hard fiber impurities on local of the surfaces pasted with the films of the mobile phones and the slight cracking phenomenon of the film surfaces caused by the hard fiber impurities during film pasting and pressing are prevented.

Description

technical field [0001] The invention relates to the field of film sticking technology, more precisely, it is a mobile phone vacuum film sticking machine with air convection and anti-indentation. Background technique [0002] With the gradual development of science and technology, mobile phones, as one of the important electronic devices for communication and social interaction, bring enough convenience to people's lives. Because the surface of mobile phones is relatively fragile under the action of bumps, it is easy to break. When it is used for protection and explosion-proof, film stickers are usually used for protection. When a large number of mobile phone films are pasted, a film sticking machine is used to stick films one by one in a flow-type manner. [0003] However, when the mobile phone is sticking the film, because of the flow of the surrounding air, the fiber impurities in the air will directly fly down on the surface of the mobile phone film shell, resulting in th...

Problems solved by technology

[0003] However, when the mobile phone is sticking the film, because of the flow of the surrounding air, the fiber impurities in the air will directly fly down on the surface of the mobile phone film shell, resulting in the contact surface between the film and the mobile phone shell due to the fiber impurities during the film sticking. Due to the hard fiber impurities and the downward pressure of the external force, slight cracks and bubbles appear in the film. At the same time, because the surface of the mobile phone is relatively smooth, under the downward pressure of the external force, due to its own characteristics It will cause the mobile phone to move
