Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts film application process, specifically to a rotary film application machine for automotive parts. Background Technology

[0002] In the manufacturing process of automotive parts, many components (such as interior panels, dashboard components, and control panels) require a protective or decorative film to be applied to their surfaces to prevent scratches during transportation, storage, and assembly, or to achieve specific aesthetic effects. Traditional manual film application relies heavily on the experience and feel of operators, resulting in low production efficiency, high labor intensity, and difficulty in guaranteeing application accuracy and consistency. Especially for parts with curved surfaces or complex contours, manual application is highly prone to producing defects such as bubbles, wrinkles, and misalignment, leading to material waste and increased production costs.

[0003] To improve the level of automation, people have invented semi-automatic or automatic film-applying equipment, but the film-applying equipment has the following problems: (1) The existing material loading and unloading method adopts synchronous loading and unloading, that is, after the material loading, film application, and unloading, the material is replaced and then transported to the processing station for processing. The process connection is not smooth, the overall cycle is slow, and it cannot meet the needs of high-efficiency production; (2) The positioning accuracy of the fixture is insufficient, and small displacements are easy to occur during the film application process, which affects the film application quality; (3) The degree of freedom of the film application mechanism is limited, making it difficult to perfectly fit complex curved surfaces; (4) There is a lack of high-precision visual positioning system, which cannot automatically compensate for the position deviation of the parts, and the accuracy requirements for manual loading are too high.
