On one side, a film sticking mechanism for controlling the flow direction of film sticking by the internal airflow of pneumatic film sticking is connected with the vacuum mechanism, and the vacuum mechanism inflates the film sticking mechanism for controlling the flow direction of film sticking by the internal airflow of pneumatic film sticking during film sticking, so as to stick the film on the mobile device; the clamping space is also connected with the vacuum mechanism, and the vacuum mechanism evacuates the clamping space during film sticking, with the purpose of evacuating the clamping space and inflating the film sticking mechanism for controlling the flow direction of film sticking by the internal airflow of pneumatic film sticking at the same time, so that the air pressure in the film sticking mechanism for controlling the flow direction of film sticking by the internal airflow of pneumatic film sticking is greater than the air pressure in the clamping space, making it easier to inflate, thereby making it easier to stick the film on the mobile device, thereby improving the film sticking efficiency.

[0004] The above-mentioned vacuum automatic film laminating machine also records that the airbag film laminating method is to start the film laminating machine, inflate the airbag through the vacuum mechanism, and at the same time, evacuate the clamping space through the vacuum mechanism.

There will still be multiple contact points between the airbag and the film. Multiple contact points will jointly apply the film to the mobile phone screen, and there will still be bubbles, white edges, airflow marks, etc. on its surface, which may easily lead to defective products.

When the vacuum component 3 evacuates the upper and lower cavities b, the upper cavity a controls the gas flow rate of the pressure relief port a1 through the throttling speed control component 6 and the vacuum component 3, so that the working path of the soft film 5 can start airflow control at the center position to ensure priority action, and realize the airflow design starting from the center and gradually extending to the surrounding areas, effectively avoiding defects such as bubbles, white edges and airflow marks after film pasting, and improving the yield rate.

[0057] To achieve the above purpose, refer to Figure 1-3 As shown, the utility model provides a film laminating machine for controlling the flow direction of film laminating by airflow inside pneumatic film laminating, comprising a shell 1, a mounting window 11 being arranged on the surface of the shell 1; a clamping assembly 2 adapted to the mounting window 11, the clamping assembly 2 being arranged in the mounting window 11; a vacuum pumping assembly 3, the vacuum pumping assembly 3 being arranged inside the shell 1; a capping assembly 4, the capping assembly 4 being sealed and connected to the top of the mounting window 11 of the shell 1; a soft film 5, the soft film 5 being arranged at the bottom of the capping assembly 4; and a center of the soft film 5. The upper part of the soft plastic sheet 5 is aligned with the middle part of the clamping component 2, and an upper cavity a is formed between the soft plastic sheet 5 and the sealing component 4. The upper cavity a is provided with a pressure relief port a1, and the position of the pressure relief port a1 corresponds to the middle part of the soft plastic sheet 5; a lower cavity b is formed between the soft plastic sheet 5 and the installation window 11; the exhaust end of the vacuum pumping component 3 is respectively connected to the pressure relief port a1 and the lower cavity b; the throttling speed control component 6, the vacuum pumping component 3 is connected to the throttling speed control component 6, so that when the upper cavity a in the vacuum state is depressurized, the speed of the airflow discharged into the upper cavity a can be controlled.

At this time, the upper and lower cavities b are evacuated at the same time; when the evacuation reaches about -100KPA, the air in the upper and lower cavities b is extremely thin, the upper solenoid valve 32 is powered off, and the upper cavity a is stopped from being evacuated. The upper solenoid valve 32 is powered off for about 5 to 10 seconds, and the pressure relief solenoid valve 34 is powered on and opened, and the upper cavity a is connected to the atmosphere through the pressure relief solenoid valve 34, and the pressure of the upper cavity a is relieved. The speed control valve is opened while the pressure is relieved. At this time, the soft film 5 is under the pressure of atmospheric pressure, and the speed control valve will gradually inhale gas from the pressure relief port a1 in the middle. The middle position of the soft film 5 will contact the gas for the first time, and start to move downward from the middle. Due to the pressure difference between the upper and lower cavities b, the soft film 5 keeps the middle part bulging first.

The middle position of the soft film 5 will contact the gas for the first time, and start to move downward from the middle. The soft film 5 starts to contact the film 10 from the lowest position in the middle. Under the pressure difference and the speed control inflation, the soft film 5 continues to expand and press down, and gradually fits from the middle of the screen of the mobile phone 9 to both ends until the film 10 is completely pressed on the mobile phone 9.
