Description

Technical Field

[0001] The present invention relates to the technical field of film sticking machinery, and more specifically, to a film sticking mechanism used for automatic assembly. Background Art

[0002] In the production process, some products need to be covered with a film on certain parts due to the technical requirements of processing. After the processing is completed, there must be no creases or bubbles in the film, otherwise it needs to be redone. The existing method is usually to use manual film pasting, but the efficiency of manual film pasting is low, and the effect after film pasting often needs to be redone. This practice greatly increases the company's labor costs and quality problems; some companies also use a simple downward pressure mechanism to achieve automatic film pasting. This practice effectively replaces manual labor, but the unreasonable mechanism often causes problems with the mechanism, which requires manual processing, resulting in low production continuity, low efficiency, and difficulty in ensuring product quality. Summary of the invention

[0003] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a film pasting mechanism used for automatic assembly, which can adjust the angle during production to adapt to the shape of the incoming film, and paste the film at a certain inclination, effectively removing problems such as creases or bubbles in the film, thereby achieving the purpose of stable production, greatly improving the efficiency of film pasting, and reducing the machine maintenance rate and the comprehensive labor cost of the enterprise.

[0005] In this device, the transverse driving device controls the horizontal movement of the film sticking head, the longitudinal driving device controls the vertical movement of the film sticking head, and the first rotating device is added to realize the rotation angle adjustment of the film sticking head around the Y axis, and the second rotating device realizes the rotation angle adjustment of the film sticking head around the Z axis. In this device, the film sticking head can realize the adjustment in four directions of X, Z, β, and γ. For the same batch of incoming films, the γ direction of the film sticking head is adjusted by the second rotating device, and the β direction of the film sticking head is further adjusted by the first rotating device. Then, the X and Z directions of the film sticking head are adjusted in combination with the transverse driving device and the longitudinal driving device. The film sticking head moves from the film stripping position to the top of the film sticking position along the X axis direction, and further, the film sticking head descends from the top of the film sticking position to the film sticking position along the Z axis direction. Through this device, the angle of the film sticking head can be adjusted in the production process to adapt to the incoming film shape, and the film is applied at a certain slope, which can effectively remove problems such as creases or bubbles in the film, achieve the purpose of stable production, greatly improve the film sticking efficiency, and reduce the machine maintenance rate and the comprehensive labor cost of the enterprise.

Four linear bearings, buffer shafts and springs are respectively arranged on the four end corners of the film sticking mounting plate.
