[0027] The film sticking part 12 includes: a film sticking cavity 121 and an upper cover 122, the upper cover 122 includes: an air bag 1221, the air bag 1221 is connected with one end of the air pipe 13, one end of the air pipe 13 is arranged at the center of the air bag 1221, the other end of the air pipe 13 is connected with the air outlet of the air pump 11, and the air pump 11 is arranged inside the base 10;

[0028] The film sticking cavity 121 is further provided with an air hole 1211 , and the air hole 1211 is communicated with the air inlet of the air pump 11 .

[0029] See also Figure 1 , Figure 2The working principle of the vacuum film laminating machine provided by the present application is as follows: after the positioning of the film to be pasted and the mobile phone is determined, the mobile phone to be pasted is placed in the film laminating cavity 121, and then the upper cover 122 is closed, so that the film laminating cavity 121 is isolated from the air, and the air pressure in the film laminating cavity 121 is at normal pressure. At this time, the air pump 11 works to suck out the air in the film laminating cavity 121 through the air hole 1211, so that the air pressure in the film laminating cavity 121 is reduced, and the air pump 11 sucks air into the airbag 1221, and the airbag 1221 becomes larger, so that the airbag 1221 is The middle part will be pressed against the middle of the mobile phone to press the film to be applied and the mobile phone. As the amount of air inhaled increases, the volume of the airbag 1221 becomes larger and larger, and the film to be applied and the mobile phone can be directly wrapped. Since the technical solution of the present application is pressed from the middle of the film to be applied, the appearance of bubbles can be avoided. In addition, the technical solution of the present application is pressed through the change of air pressure, and the gas has strong fluidity, so its pressure is relatively uniform, which makes the pressure of the film uniform and avoids directly crushing the mobile phone. Therefore, it improves the quality of the film and improves the user experience.

[0030] See also Figure 3 , Figure 4 , Figure 5 This is a schematic diagram of the bonding of the technical solution of this application, such as Figure 3 As shown, it is the initial stage of lamination. In this initial stage, since one end of the air tube 13 is arranged at the center of the air bag 1221, the gas blows the middle part of the air bag 1221 so that the middle part is in contact with the mobile phone film. Figure 4 , Figure 4 For the middle stage of laminating, the airbag 1221 is slowly squeezed from the middle to both sides to laminat the films on both sides. Figure 5 As shown, Figure 5 This is the completion stage of the film's fitting. For the completion stage, the airbag 1221 is fully deployed, slowly wrapping the curved surfaces on both sides (such as 3D curved surfaces), so that the film fits completely, thereby being able to adapt to all mobile phone models and having the advantage of a wide range of references.

[0031] Optionally, a heat insulation plate 30 and a temperature control plate 31 are further provided inside the airbag 1221. After the temperature control plate 31 is provided, the airbag can be heated to make the film fit better.

[0032] The outer surface 32 of the airbag 1221 can be made of sheepskin, cowhide, artificial leather, etc. These materials can make the film fit better.

[0033] Optionally, the airbag 1221 also includes: two diaphragms 15, which divide the airbag 1221 into a middle cavity 16 and two side cavities 17. One end of the air tube 13 is connected to the common end of the two-way valve 70. The first branch end of the two-way valve 70 is connected to the middle cavity 16. The second branch end of the two-way valve 70 is connected to the solenoid valve 71, which connects the two side cavities 17. The solenoid valve 71 is used to open and close after a set delay time.

[0034] The main purpose of the above technical features is to better fit the curved mobile phone film. Figure 3 , Figure 4 , Figure 5 , Figure 6 ,exist, Figure 3 , Figure 4 In the stage, only the outer surface of the middle cavity 16 needs to be attached to the mobile phone film. At this time, the side cavity does not need to be ventilated, so the outer surface of the side cavity 17 is not tightly attached to the mobile phone film. Figure 5 In the stage shown, that is, after the set time, the electromagnetic valve 71 opens and closes, and the two side cavities 17 are ventilated, so that the pressure on the edge increases, and the curved mobile phone film is adhered. Therefore, its structure can make the curved mobile phone film fit better.

[0035] Optionally, the vacuum laminating machine may further include a delay control circuit, such as Figure 7 As shown, the delay control circuit includes: a power supply, a transformer T, a transistor T1, a bridge rectifier circuit 80, an electromagnetic valve 71, and a pressure sensor; wherein the power supply is connected to both ends of the primary side of the transformer T1, one end of the secondary side of the transformer T1 is connected to port 1 of the bridge rectifier circuit 80, the other end of the secondary side of the transformer T1 is connected to port 3 of the bridge rectifier circuit 80, port 4 of the bridge rectifier circuit 80 is connected to the collector of the transistor T1, the emitter of the transistor T1 is connected to one end of the electromagnetic valve 71, the other end of the electromagnetic valve 71 is connected to port 2 of the bridge rectifier circuit, the base of the transistor T1 is connected to the output end of the comparator, the positive input end of the comparator is connected to the output end of the pressure sensor, the reverse input end of the comparator is connected to the voltage source VCC, and the pressure sensor is arranged in the middle cavity 16, one end of the pressure sensor is connected to port 4 of the bridge rectifier circuit, and the other end is grounded.

[0036] The implementation principle is that when the vacuum laminating machine is powered on, the power supply is transformed by the transformer and the bridge rectifier circuit to enable the pressure sensor to be powered on and work. At this time, the pressure in the middle cavity 16 is relatively small, so the voltage value output by the pressure sensor is relatively small. As the pressure in the middle cavity 16 increases with the passage of time, the voltage value output by the pressure sensor increases. When it is greater than VCC, the comparator outputs a high level, and the solenoid valve is powered on and opened and closed, so that the side cavity 17 can be inflated and work.
