Embodiment Construction

[0020] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] Such as figure 1 with figure 2 As shown, the present invention provides an automatic film sticking device, comprising: a frame 90, a box body 10 located in the frame 90, a negative pressure chamber 20a and a positive pressure chamber 20b are provided in the box body 10; wherein the negative pressure chamber 20a It is suitable for absorbing the mobile phone film 1, and when the box body 10 moves downward, so that the mobile phone film 1 is attached to the surface of the mobile phone screen, the positive pressure chamber 20b gradually exerts a pressing force from one side of the mobile phone film 1 to the other side , that is to discharge the gas betwe...

Abstract

The invention relates to a positive and negative pressure switching automatic film pasting device. The positive and negative pressure switching automatic film pasting device comprises a box body. A negative pressure cavity and a positive pressure cavity are arranged in the box body. The negative pressure cavity is suitable for adsorbing a mobile phone screen protecting film, and extrusion force is gradually applied from one side of the mobile phone screen protecting film to the other side of the phone screen protecting film through the positive pressure chamber when the box body moves downwards until the mobile phone screen protecting film is adsorbed to the surface of a mobile phone screen. The positive and negative pressure switching automatic film pasting device is provided with a low-pressure cavity and an adsorbing plate, the mobile phone screen protecting film can be placed under one side of the low-pressure cavity and adsorbed via through holes in a through hole surface, and finger print marks caused by hand contact can be effectively avoided. Through gradual transition from negative pressure to positive pressure, the mobile phone screen protecting film adsorbed to the adsorbing plate on one side of the low-pressure cavity is gradually subjected to the action of push force of a high-pressure cavity from one side, generation of bubbles is avoided, and the mobile phone screen protecting film is gradually extruded to the mobile phone screen. After the mobile phone screen protecting film completely breaks away from the low-pressure cavity and is subjected to the action of the high-pressure cavity, film pasting of a mobile phone is completed. The positive and negative pressure switching automatic film pasting device can paste the film to the mobile phone automatically, reduces the use of manpower and material resources, and has the advantage of good pasting effect.

Description

technical field [0001] The invention relates to the technical field of mobile phone film sticking, in particular to an automatic film sticking device suitable for switching between positive and negative pressures. Background technique [0002] With the continuous advancement and innovation of science and technology, smart phones have become very popular. In order to protect their screens, people generally add a protective film to their screens. [0003] Generally, you will find a professional film manufacturer to do it for you, regardless of the cost, and once you find that the protective film is crooked or worn out and needs to be replaced in the future, you have to go to the merchant to do it again, which is quite troublesome; if you apply the film yourself, Air bubbles are often produced, affecting the screen effect. [0004] Therefore, how to design an automatic film sticking device that can easily and quickly complete the film sticking work is a technical problem in th...
