Description

Technical Field

[0001] This utility model relates to the technical field of environmentally friendly applications of release films, and more specifically, to a film peeling mechanism. Background Technology

[0002] In the 3C electronic product screen manufacturing industry, traditional film-removing stations mostly employ a one-way peeling process. After operators or automated equipment remove the protective film from the screen surface, the release film is generally discarded directly as waste. Existing film-removing mechanisms primarily focus on improving peeling efficiency and yield, without considering the recycling of the protective film. Summary of the Invention

[0003] This invention provides a release film peeling mechanism, which solves the problem of reusing release films.

[0004] In a first aspect, the peeling mechanism provided by this utility model includes a driving component and a first film-peeling component, the first film-peeling component being mounted on the first driving component and used to peel the film off the object to be covered; it also includes a demolding component, the demolding component being connected to the second driving component and capable of moving in the direction of film removal, the demolding component being provided with an adsorption device capable of adsorbing the film. Since high-end screen protectors mostly use optical-grade PET material, the cost per sheet can reach several yuan, and hundreds of kilograms of film waste are generated daily in large-scale production, causing both resource waste and increased processing costs. More importantly, some special processes (such as rework inspection) require precise re-application of the original protective film, but existing technologies lack the functions of film material positioning, temporary storage, and secondary application: the peeled protective film is prone to wrinkles and foreign matter contamination, and due to the lack of positioning reference, the re-application offset exceeds ±0.5mm (manual), failing to meet the high-precision requirements of screen assembly. Therefore, the peeling mechanism here enables the release film to be positioned, temporarily stored, and accurately re-attached. By improving the film material processing flow, the protective film can be recycled, which is of great value for reducing production costs and improving the green level of the production line.

[0005] Preferably, the demolding component is a plate-like structure with a smooth end surface to prevent damage to the film during the film-tearing process.

[0006] Preferably, the adsorption device on the plate-like structure is a negative pressure adsorption, which is cheaper and more stable.

[0007] Preferably, the first film-peeling component includes a suction head for adsorbing and connecting with the film on the surface of the object to be covered, which is cheaper, more stable, and easier to replace.

[0008] Preferably, the first film-tearing component includes a first linkage mechanism, and the suction head is driven to move by the first linkage mechanism. When used in high-precision machines, where the drive components require frequent maintenance and adjustment, the linkage mechanism is more economical.

[0009] Preferably, the surface of the demolding component that comes into contact with the film has a planar structure, which better fits the torn film.

[0010] Preferably, the surface of the demolding component that comes into contact with the film has a curved structure, which facilitates the effect of negative pressure adsorption and can also release stress to a certain extent, but the curvature here is very small.

[0011] Preferably, the first film-tearing component includes a clamping component for holding the adhesive surface of the film. The first film-tearing component includes a second linkage mechanism. The clamping component is driven to move by the second linkage mechanism. The clamping component makes the film-tearing process more stable, reduces the pressure requirement of the adsorption device, and reduces the probability of irreversible deformation of the film during the tearing process due to high pressure on one side.

[0016] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0017] To address the problem of efficient reuse after demolding in existing technologies, this invention provides a film peeling mechanism, such as... Figure 1 , 2 It includes a driving component and a first film-tearing component 7, which is mounted on a first driving component 6 and used to peel the film 2 off the film-coated object 1; it also includes a demolding component 4, which is connected to a second driving component 5 and can move in the direction of film 2 removal, and the demolding component 4 is provided with an adsorption device 3 capable of adsorbing the film 2.

[0018] The demolding component 4 is a plate-shaped structure with a smooth end surface to prevent damage to the film 2 during the tearing process. The adsorption device 3 on the plate-shaped structure uses negative pressure adsorption, which is cheaper and more stable. The surface of the demolding component 4 that comes into contact with the film 2 is a planar structure, which fits the torn film 2 better. The adsorption device 3 consists of several evenly arranged holes, and the holes are designed to draw air to create negative pressure.

[0019] The first film-peeling component 7 includes a suction head for adsorbing and connecting with the film 2 on the surface of the film-applied object 1, making it cheaper, more stable, and easier to replace. The first film-peeling component 7 includes a first linkage mechanism 8, and the suction head is displaced by the first linkage mechanism 8. Figure 1 Due to the viewing angle, the suction head is not shown. When used in high-precision machines, the drive components require frequent maintenance and adjustment. The linkage mechanism is more economical. The first drive component 6, the first film-tearing component 7, and the second drive component 5 are guide rail mechanisms.

[0020] In this embodiment, the first film-tearing component 7 includes a clamping component 9 for holding the adhesive surface of the film 2. The movement trajectory of the clamping component 9 is towards the suction head. The first film-tearing component 7 includes a second linkage mechanism. The clamping component 9 is driven to move by the second linkage mechanism. The film-tearing process is as follows: the film-applied object 1 reaches the predetermined position, the first driving component 6 and the first film-tearing component 7 work together to move. After reaching the position, the first linkage mechanism 8 acts to make the suction head adsorb the film 2. The first linkage mechanism 8 acts upward to lift the film 2. The clamping component 9 is driven to move by the second linkage mechanism so that the end of the clamping component 9 and the suction head cooperate to complete the robotic arm function and clamp the film 2. Then the suction head and the clamping component 9 move simultaneously and continue to tear the film 2 upward. At the same time, the second driving component 5 drives the demolding component 4 to start moving. The smooth end moves towards the position where the film 2 is torn, giving the film 2 and the film-applied object 1 a force to help the film 2 detach. After the film 2 is completely detached, the adsorption device 3 is activated. The film 2 is adsorbed by the negative pressure of the adsorption device 3, which facilitates subsequent recycling.

[0021] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
