Description

[0002] According to the purpose, protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and their functions in the field of screen protective films are also varied. In order to adapt to the adhesion of the screen, the protective film needs to be cut into a specific shape.

[0003] In the prior art, the forming and cutting method of the protective film is usually as follows: by setting a winding roller, a material roller and a forming and cutting device, the motor drives the winding roller to wind up the film, that is, drives the material roller to unwind, and the forming and cutting device works intermittently to obtain a protective film of a specific size. In this process, due to the uniform speed drive of the motor, as the number of turns of the film wrapped around the winding roller increases, the film moves faster, and thus the distance between two adjacent cutting areas on the film cannot be accurately controlled, which easily causes waste of the film and increases the defective rate of the product.

The tension detection roller 54 is arranged on the side adjacent to the winding roller 51. The two limit rollers 53 are arranged between the unwinding roller 52 and the tension detection roller 54. A servo motor 14 for driving the winding roller 51 to rotate is installed on the frame 1; a tension detector 12 is installed at the end of the limit roller 53. The installed tension detector 12 can detect the tightness of the protective film body 3. When the protective film body 3 is relaxed, the servo motor 14 drives the winding roller 51 to rotate, thereby realizing the winding of the protective film body 3; the collection box 2 is arranged at the bottom end of the frame 1.

[0030] The stamping and forming mechanism is installed on the frame 1, and the stamping and forming mechanism includes a horizontal plate A15, a clamping frame 18, a cutter 19, a horizontal plate 20, a linear drive mechanism C22, a vertical rod 23 and multiple sets of elastic reset components. A gantry 6 is provided on the frame 1, and the linear drive mechanism C22 is installed on the gantry 6. The vertical rod 23 is connected to the output shaft of the linear drive mechanism C22. The clamping frame 18 is arranged at the bottom end of the horizontal plate A15 and surrounds the horizontal plate A15. The horizontal plate 20 is arranged below the horizontal plate A15. The cutter 19 is installed on the horizontal plate 20. The vertical rod 23 It movably penetrates the horizontal plate A15 and is connected to the horizontal plate 20. The horizontal plate A15 and the horizontal plate 20 are elastically connected through multiple groups of elastic reset components. The elastic reset component includes a guide rod 25, a spring 26 and a limit block 27. The guide rod 25 is fixedly connected to the horizontal plate 20. The upper end of the guide rod 25 movably penetrates the horizontal plate A15 and is connected to the limit block 27. The spring 26 is mounted on the guide rod 25. The setting of the elastic reset component enables the cutter 19 set after the clamping frame 18 presses the membrane body to continue to move downward to achieve cutting of the membrane body.

[0031] The support plate 4 has a through hole 401 . The support plate 4 is mounted on the frame 1 and is located between the collecting box 2 and the stamping and forming mechanism, and is used to support the upper horizontal portion of the protective film body 3 .

[0032] The clamping mechanism is used to clamp the protective film body 3, and the clamping mechanism includes a rectangular frame 7, a linear drive mechanism B13 and a clamping rod 16. The clamping rod 16 is arranged on the inner side of the rectangular frame 7, and the linear drive mechanism B13 is installed on the rectangular frame 7 to drive the clamping rod 16 to rise and fall. The clamping rod 16 and the inner bottom end of the rectangular frame 7 are both installed with anti-slip rubber strips 17; the moving mechanism is installed on the frame 1 to drive the clamping mechanism to move, and the moving mechanism includes a linear drive mechanism A8. The end of the rectangular frame 7 is connected to a connecting slider 10, and the rectangular frame The frame 7 is slidably mounted on the frame 1 through the connecting slider 10, the linear drive mechanism A8 is mounted on the side of the frame 1 and its output shaft is connected to the connecting slider 10; the distance measuring mechanism is mounted on the frame 1, and is used to detect the displacement data of the clamping mechanism. The distance measuring mechanism includes a magnetic scale 11 and a magnetic head 111 slidably mounted on the magnetic scale 11, the magnetic scale 11 is mounted on the side of the frame 1, and the magnetic head 111 is connected to the connecting slider 10. The movement of the clamping mechanism drives the magnetic head 111 to slide on the magnetic scale 11, so that the moving distance of the clamping mechanism can be detected.

[0033] In this embodiment, when working, the linear drive mechanism C22 is started to drive the horizontal plate 20 to move downward, that is, the horizontal plate A15 is driven to move downward, and the clamping frame 18 clamps and fixes the required cutting part on the protective film body 3. With the continuous driving of the linear drive mechanism C22, the cutter 19 can be driven to move downward, and the cutter 19 starts to cut the protective film body 3. Then, the linear drive mechanism C22 drives the clamping frame 18 and the cutter 19 to reset. After the cutting work is completed, the part on the protective film body 3 is first clamped by the clamping mechanism, and then the linear drive mechanism A8 is started to drive the clamping mechanism to move. The distance measuring mechanism can measure the displacement length of the clamping mechanism. When it is detected that the clamping mechanism moves to the set position, the controller 9 controls the clamping mechanism to release the clamping work of the protective film body 3 (the controller 9 is electrically connected to the multiple driving devices provided). In summary, in the process of cutting the protective film, the utility model first presses and fixes the edge of the protective film to be cut, and then cuts it, thereby improving the processing effect on the film body, and with the cooperation of the clamping mechanism, the moving mechanism and the distance measuring mechanism, it can ensure that the movement length of the film body is equal each time, thereby reducing the waste of the film body and ensuring the processing effect of the film body.
