Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic product film pasting, in particular to an automatic film pasting machine and a film pasting method. BACKGROUND

[0002] With the popularity of electronic products, screen film pasting as an important link to protect the screen and improve the use experience, the demand for automatic film pasting equipment is increasing. Traditional film pasting process relies on manual operation, which has low efficiency, poor precision, and is prone to bubbles or edge lifting. Although the existing automatic film pasting machine has achieved automation to some extent, it still has the following technical bottlenecks:

[0003] 1. Insufficient film pasting precision and pasting effect: In the film pasting process of existing equipment, the initial pasting of the film and the screen (especially curved screens) relies on simple pressing action, which cannot guarantee the complete pasting of the film and the screen, and is prone to edge lifting or bubble residue. Some equipment increases the rolling process, but only single rolling cannot completely solve the problem of loose edge pasting.

[0004] 2. Low waste film processing efficiency: After film pasting, the waste film (such as release film) needs to be separated and collected. Traditional equipment usually needs manual removal of waste film or separate processing by additional mechanisms, which not only affects production efficiency, but also may interfere with the subsequent film pasting process due to waste film residue.

[0005] 3. Poor film adaptability: Different models of electronic products (such as different sizes of tablets, mobile phones or curved screen devices) have different requirements for film size and shape. The existing equipment's clamping fixture is mostly fixed structure, which is difficult to adapt to multiple sizes of electronic products, and the film storage rack's material taking mechanism lacks flexibility, which is difficult to adapt to different heights of film stacking.

[0006] 4. Lack of continuity in film pasting process: Some equipment separates film pasting and film pressing into independent processes, which requires multiple transfers of electronic products, which is prone to film pasting failure due to positioning deviation. At the same time, there is a lack of effective means for secondary pressing of pasted film (such as edge reinforcement pressing for curved screens), which further limits the pasting effect.

[0007] Therefore, an automatic film pasting machine and a film pasting method are proposed. SUMMARY
