Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electronic production, and specifically relates to a device for automatically capturing and removing a film attached to the surface of a product. BACKGROUND

[0002] In various production and manufacturing equipment, the film tearing process is a common and important operation link and is widely used in many fields such as electronics, packaging, and automobile parts manufacturing. For example, in the manufacturing process of electronic equipment, the surfaces of many parts are covered with protective films, which need to be torn off before subsequent processing; in the packaging industry, the pasting and removal of labels also involve similar film tearing operations.

[0003] Traditional film tearing assemblies have many defects in actual application. First, the position and angle of the film tearing assembly designed in the traditional way are fixed after adjustment and lack adjustability. This is because the film tearing assembly is usually installed independently, and in order to ensure its stability during operation, the angle or position cannot be adjusted after installation. Especially in complex and compact equipment, different components are closely arranged, and the spacing between components needs to be carefully planned to prevent interference, which further limits the possibility of adjusting the film tearing assembly. When the production requirements change, such as changes in product specifications or adjustments in production processes, it is often necessary to stop the machine and re-adjust the position or angle of the film tearing assembly, which not only consumes a lot of adjustment time, but also interrupts production, seriously affecting production efficiency and increasing production costs. Second, the traditional design of the clamping jaw also has shortcomings. The traditional clamping jaw usually uses a workpiece to clamp and tear the film, which has a high risk of film tearing failure in actual operation. Because the material, thickness, and surface characteristics of the film to be torn are different, simply relying on the clamping of the workpiece cannot guarantee that the film can be stably grabbed and smoothly torn under various conditions, and problems such as incomplete tearing of the film, tearing or damage of the film during the tearing process, etc. may occur, affecting product quality and production continuity.

[0004] With the continuous development of manufacturing industry, production equipment is developing towards miniaturization, multifunctionalization, modularization, and high efficiency, which puts higher requirements on the space occupation, flexibility, and automation level of the internal components of the equipment. Under this trend, the traditional film tearing assembly has been difficult to meet the needs of modern production, and a new type of film tearing assembly that can save space, enhance flexibility and automation capability is needed to solve the above problems to adapt to the growing production needs and complex production environment.
