[0002] A headphone charging shell is a charging device applied to wireless Bluetooth headphones, and the wireless Bluetooth headphone body is placed therein to charge the wireless Bluetooth headphones.

[0003] During the assembly process of the headphone charging shell, since magnetic processing needs to be performed on the inside of the headphone charging shell, some debris will be ejected onto the outer side wall of the headphone charging shell during the processing, which easily leads to a high particle feeling on the outer wall of the headphone charging shell. When processing again, dust will be processed together, resulting in errors. Therefore, a protective film is pasted on the outer wall of the headphone charging shell to prevent dust from accumulating on the surface of the headphone charging shell.

[0004] In the existing processing technology of headphone charging shells, after detecting and processing the outer wall of the headphone charging shell, before blanking, the protective film on the surface needs to be torn off before the final grinding process on the surface of the headphone charging shell can be carried out. However, the traditional film tearing is manually performed by workers, and insufficient force will cause the film body to remain, thus affecting the subsequent processing quality. Therefore, there is a problem that the existing film tearing process cannot completely tear off the film manually. Content of the Utility Model

[0007] Preferably, an adjustment groove is formed on one side of the rotary base, an adjustment member is rotatably connected in the adjustment groove, and the adjustment member is rotatably connected to the front end of the rotary telescopic cylinder.

[0008] Preferably, one end of the horizontal moving plate is fixedly connected to a processing platform, and the opening of the film tearing jaw faces the direction of the processing platform.

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Referring to Figures 1-4 , a film tearing base 1 is designed. A rotary film tearing mechanism 2 is designed on the film tearing base 1. The rotary film tearing mechanism 2 can rotate and tear the protective film on the surface of the earphone charging case and remove the protective film, ensuring that there will be no residue on the surface after the protective film is torn off or the protective film is damaged.

[0024] Referring to Figures 1-4 , the rotary film tearing mechanism 2 includes a rotary telescopic cylinder 21 and a rotary member 22. The output end of the rotary telescopic cylinder 21 can perform telescopic movement and drive the rotary member 22 to rotate. The rotary film tearing mechanism 2 further includes a rotary base 23. A rotary shaft 24 is rotatably connected to the rotary base 23. The rotary member 22 and the rotary shaft 24 are fixedly connected. One end of the rotary member 22 is fixedly connected with a film tearing jaw 25. By the telescopic movement of the rotary telescopic cylinder 21, the rotary member 22 is driven to rotate, thereby driving the film tearing jaw 25 to adjust the clamping angle, achieving the effect of flipping the jaw.

[0025] Referring to Figures 1-4 , a horizontal moving plate 26 is fixedly connected to the bottom of the rotary base 23. The horizontal moving plate 26 can drive the film tearing jaw 25 to adjust the clamping horizontal position. A film tearing slide rail 11 is fixedly connected to the film tearing base 1. The horizontal moving plate 26 is slidably connected to the film tearing slide rail 11. An obtuse angle is formed between the rotary base 23 and the film tearing slide rail 11, thereby forming a torque of the included angle, which can more easily contact the inner corner of the protective film during the film tearing process and improve the quality of film tearing. One end of the horizontal moving plate 26 is fixedly connected with a processing platform 261. The opening of the film tearing jaw 25 faces the direction of the processing platform 261. The processing platform 261 can place the product to be film torn. The film tearing operation is performed by the film tearing jaw 25. A film tearing push cylinder 251 is arranged at the end of the film tearing jaw 25. The output end of the film tearing push cylinder 251 faces the direction of the processing platform 261, pushing the film tearing jaw 25 towards the direction of the processing platform 261.

[0026] Referring to Figures 1-4 , a waste collection device 27 is arranged at the bottom end of the horizontal moving plate 26. The opening of the waste collection device 27 faces the lower part of the opening of the film tearing jaw 25, which can handle waste after film tearing. The film tearing jaw 25 is loosened to let the torn protective film fall into the waste collection device 27. A vacuum negative pressure gauge 28 is fixedly connected to one end of the horizontal moving plate 26. The vacuum negative pressure gauge 28 is electrically connected to the rotary telescopic cylinder 21, which can detect the torque of the rotary telescopic cylinder 21, thereby ensuring the accuracy of the rotation position of the jaw.

[0027] The working principle of this mechanism is as follows: When the film tearing process is carried out, when the previous process transports the earphone charging case with the protective film, first start the driving device of the horizontal moving plate 26. The driving device of the horizontal moving plate 26 is electrically connected to the overall process and can be adjusted externally to move the horizontal moving plate 26 to the position where film tearing is required. At this time, start the rotary telescopic cylinder 21, so that the output end of the rotary telescopic cylinder 21 pushes the rotating part 22 to adjust the clamping angle of the film tearing jaw 25. Start the film tearing propulsion cylinder 251 to approach the product to be film torn, clamp one end of the protective film, and then start the driving device of the horizontal moving plate 26 again to tear it off. Move the film tearing jaw 25 clamping the protective film above the opening of the waste collection device 27, and the film tearing jaw 25 will release the waste and fall into the waste collection device 27, thus completing the film tearing process and achieving the effect of automatic film tearing.

[0028] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be understood to be within the protection scope of the present invention.
