Description

Technical Field

[0001] This utility model relates to the technical field of front cover film tearing equipment, specifically to a film clamping mechanism for an automatic front cover film tearing equipment. Background Technology

[0002] In the production of electronic devices, the front cover is used as a decorative cover. In order to ensure its aesthetics, a protective film needs to be applied during the production process. This film is called a process film and needs to be removed after production is completed.

[0003] The release film on the front cover is located on the inside of the cover. Manually tearing it is time-consuming, labor-intensive, inefficient, and costly. While automated film-tearing equipment can address this issue, the clamping process presents several challenges. First, the release film is located on the inside of the front cover, leaving the outside for the clamping mechanism; clamping from the outside is not feasible. Furthermore, the release film is thin and adheres to the inner edge of the front cover, making four-sided clamping more complex and costly. Additionally, tearing from the center presents greater resistance, increasing the risk of the release film detaching from the clamping mechanism or tearing, leading to tearing failure. Therefore, those skilled in the art have provided a clamping mechanism for an automated front cover film-tearing device to solve the problems described in the background. Utility Model Content

[0004] The purpose of this utility model is to provide a film clamping mechanism for an automatic front cover film-tearing device, solving the following technical problems:

[0012] Furthermore, the transverse clamping assembly also includes a slider assembly and a guide rail assembly. The slider assembly is slidably connected above the guide rail assembly, the guide rail assembly is fixed to the mounting plate, a mounting base is fixed to the upper end face of the slider assembly, and the lower end of the support plate is fixedly connected to the mounting base.

[0013] Furthermore, the slider assembly includes a slider body, a groove is formed on the lower end face of the slider body, a through groove is formed on one side of the groove and an adjusting screw is threadedly connected thereto, and an adjusting rod is fixed on the other side;

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see the appendix Figures 1 to 4 As shown, the film clamping mechanism of the automatic film-tearing device for front cover in this embodiment of the present utility model is applied to the front cover film-tearing device 1 and is used to clamp the front cover 5. The release film 6 is bonded to the inner side of the front cover 5. It includes a mounting plate 2, which is L-shaped, and a transverse film clamping assembly 3 and a longitudinal film clamping assembly 4 are respectively installed on both sides of the upper end face. The transverse film clamping assembly 3 and the longitudinal film clamping assembly 4 are set at 90°.

[0030] The transverse film clamping assembly 3 and the longitudinal film clamping assembly 4 have the same structure, both including a film clamping cylinder 31. The upper end of the film clamping cylinder 31 is fixedly connected to a film clamping plate 32, and the outer end of the film clamping cylinder 31 is fixed to a support plate 33. This film clamping mechanism is installed at the film tearing station of the front cover film tearing device 1. In use, the front cover 5 is loaded manually or by a material handling robot. In the initial state, the film clamping cylinder 31 is raised. During film clamping, the release film 6 of the front cover 5 is clamped between the film clamping plate 32 and the support plate 33.

[0031] In this embodiment, the film plate 32 includes a plate body 321, and two pressure blocks 322 are fixed at the corners of the plate body 321. The included angle between the two pressure blocks 322 is 90°. The support plate 33 includes an L-shaped plate 331, and two support blocks 332 are fixedly connected to the upper end of the corner of the L-shaped plate 331. The two support blocks 332 are aligned with the two pressure blocks 322.

[0032] When clamping the front cover 5, the front cover 5 is placed on the upper end of the transverse clamping assembly 3 and the longitudinal clamping assembly 4. The two clamping plates 32 clamp the two release films 6 diagonally. By clamping diagonally, the release film 6 on the inner side of the front cover 5 can be fully clamped, the clamping is stable, the success rate of tearing the film is high, and it is not easy for the release film 6 to fall off or fail to tear the film. In the clamping state, the corners of the release film 6 are clamped between the pressure block 322 and the support block 332. The release film 6 can be torn off by pulling the front cover 5 manually or by a robot.

[0033] The upper end face of the pressure block 322 is set at an angle to facilitate the guide of the release film 6 into the clamping area when it comes into contact with the release film 6.

[0034] Example 2

[0035] Please see Figures 2 to 5 As shown, based on Embodiment 1, the transverse film clamping assembly 3 further includes a slider assembly 35 and a guide rail assembly 36. The slider assembly 35 is slidably connected above the guide rail assembly 36, and the guide rail assembly 36 is fixed to the mounting plate 2. The upper end face of the slider assembly 35 is fixed with a mounting base 34, and the lower end of the support plate 33 is fixedly connected to the mounting base 34. By setting the slider assembly 35 and the guide rail assembly 36, the installation positions of the transverse film clamping assembly 3 and the longitudinal film clamping assembly 4 can be adjusted to adapt to front covers 5 of different specifications.

[0036] Specifically, the slider assembly 35 includes a slider body 351, with a groove 354 on the lower end face of the slider body 351. A through groove 356 is provided on one side of the groove 354, and an adjusting screw 357 is threadedly connected thereto. An adjusting rod 355 is fixed on the other side. The guide rail assembly 36 includes a guide rail body 361. The groove 354 matches the cross-sectional shape of the guide rail body 361 and slides in connection. Due to the through groove 356, when the adjusting screw 357 is rotated, the side of the groove 354 near the through groove 356 will deform, thereby clamping the guide rail body 361 and achieving a limit. Similarly, loosening the adjusting screw 357 will release the limit and facilitate subsequent adjustments.

[0037] The adjustable rod 355 is designed to facilitate manual pushing of the slider assembly 35.

[0038] In this embodiment, a groove 352 is provided on the top of the slide groove 354, and a protruding post 353 is fixed inside the groove 352. A protruding strip 362 is fixed on the upper end of the guide rail body 361. Limiting posts 363 are fixedly connected to both ends of the protruding strip 362. The protruding strip 362 slides in conjunction with the groove 352. By setting the limiting post 363 and the protruding strip 362, the slider body 351 can be limited to prevent the slider body 351 from exceeding the limit and falling out of the guide rail body 361.

[0039] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
