Description

Technical Field

[0001] This utility model belongs to the field of film peeling machine technology, specifically relating to a fully automatic film peeling machine for the inside of mobile phone cases. Background Technology

[0002] The fully automatic film-removing machine for mobile phone cases is a highly specialized industrial automation device. Its core function is to automatically and accurately remove the protective film attached to the inner surface of the phone case. This film serves to prevent scratches and contamination of the screen contact surface during production and transportation, but it must be removed before delivery to the consumer. The fully automatic film-removing machine integrates machine vision, precision robotic arms, and customized end effectors (such as suction cups, grippers, and adhesive rollers) to mimic and far surpass the manual film-removing action, achieving highly efficient and high-success-rate automated operation.

[0003] However, most protective films inside phone cases lack pre-tear seams, and given the complex internal structure of phone cases, existing fully automatic film-removing machines may not be able to achieve stable, fully automatic film removal using only one type of end effector. Therefore, there is an urgent need to design a fully automatic film-removing machine for phone case interiors to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic film-removing machine for the inside of mobile phone cases, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic film-removing machine for the inside of mobile phone cases, comprising:

[0010] The film-tearing mechanism includes a second slide rail parallel to the first slide rail, a second slider slidably connected to the second slide rail, a second drive motor disposed at one end of the second slide rail, and an electric gripper.

[0011] The waste box is located at one end of the film-forming mechanism and the film-tearing mechanism.

[0012] Furthermore, it also includes a feeding device, which includes a feeding conveyor belt disposed on one side of the processing platform, a feeding robot fixed to the top of the processing platform and located on one side of the positioning device, and limit plates fixed on both sides of the feeding conveyor belt, with a barrier plate fixed at one end of the limit plate.

[0013] Furthermore, it also includes a feeding device, which includes a feeding conveyor belt fixed to the top of the processing platform and a feeding robot, with a suction cup fixed to the bottom of the feeding robot.

[0014] Furthermore, the processing platform is equipped with support feet at the four corners of its bottom, and a power switch and an air supply switch are provided on one side of the processing platform.

[0031] This utility model provides, for example Figure 1-7 The fully automatic film peeling machine for the inside of a mobile phone case shown includes:

[0032] 100 processing platforms;

[0033] Positioning device 200 is fixed to the top of processing platform 100. Positioning device 200 includes positioning plate 201, limiting block 202 and spring block 203 fixed to the top of positioning plate 201, and telescopic cylinder 204 fixed to one side of positioning plate 201.

[0034] The film tearing device 300 is fixed to one side of the positioning device 200. The film tearing device 300 includes a film lifting mechanism 301, a film tearing mechanism 302, and a waste box 303.

[0035] The film-forming mechanism 301 includes a slide rail 30101, a slider 30102 slidably connected to the slide rail 30101, a drive motor 30103 disposed at one end of the slide rail 30101, and a frame column 30104 disposed on one side of the slide rail 30101. A lifting motor 30105 is provided at the top of the frame column 30104, and a lifting block 30106 threadedly connected to the output shaft of the lifting motor 30105 is provided on one side of the frame column 30104. Adjusting plates 30107 are fixed on both sides of the lifting block 30106, and a connecting block 30109 is provided between the two adjusting plates 30107. A film-forming block 30111 is fixed at one end of the connecting block 30109.

[0036] The film-tearing mechanism 302 includes a slide rail 30201 parallel to the slide rail 30101, a slider 30202 slidably connected to the slide rail 30201, a drive motor 30203 disposed at one end of the slide rail 30201, and an electric gripper 30204.

[0037] Waste box 303 is located at one end of film-forming mechanism 301 and film-tearing mechanism 302.

[0038] For example, see Figures 1-2 As shown, it also includes a feeding device 400, which includes a feeding conveyor belt 401 disposed on one side of the processing platform 100, a feeding robot 402 fixed to the top of the processing platform 100 and located on one side of the positioning device 200, and limit plates 403 fixed on both sides of the feeding conveyor belt 401, with a barrier plate 404 fixed at one end of the limit plate 403.

[0039] In this technical solution, the feeding conveyor belt 401 is used to continuously transport the mobile phone case raw materials to the processing platform 100. The setting of the limiting plate 403 and the barrier plate 404 can ensure that the mobile phone case raw materials remain stable during the transportation process and avoid deviation or falling. The feeding robot 402 is responsible for accurately grabbing the mobile phone cases on the feeding conveyor belt 401 and placing them into the positioning device 200 to prepare for the subsequent film peeling operation.

[0040] For example, see Figures 1-2 As shown, it also includes a feeding device 500, which includes a feeding conveyor belt 501 fixed to the top of the processing platform 100 and a feeding robot 502. The bottom end of the feeding robot 502 is fixed with a suction cup 503.

[0041] In this technical solution, the unloading conveyor belt 501 is used to receive and transport the mobile phone cases that have completed the film removal operation. The unloading robot arm 502 firmly grasps the mobile phone cases through the suction cup 503 at its bottom end to ensure that they will not fall or be damaged during the transfer process. Then, the mobile phone cases are placed on the unloading conveyor belt 501 for subsequent packaging or quality inspection processes. The entire unloading process is also automated, further improving production efficiency.

[0042] For example, see Figures 1-5 As shown, support feet 101 are fixed at the four corners of the bottom of the processing platform 100, and a power switch 102 and an air supply switch 103 are provided on one side of the processing platform 100.

[0043] In this technical solution, the design of the processing platform 100 fully considers the stability and ease of operation of the equipment. The support feet 101 are made of high-strength materials to ensure that the equipment will not shift or tilt due to vibration or excessive load during operation, providing a stable foundation for the film peeling operation. The power switch 102 and the air supply switch 103 are located in easily accessible positions on the processing platform 100, allowing users to control the start and stop of the equipment and the on / off of the air supply through simple operations, greatly improving the convenience and safety of operation. Through these detailed designs, this fully automatic film peeling machine for mobile phone cases not only improves the efficiency and stability of film peeling but also optimizes the operation process, bringing a better user experience.

[0044] For example, see Figure 7 As shown, there are two limit blocks 202 and two spring blocks 203. The two limit blocks 202 are arranged adjacent to each other, one spring block 203 is arranged adjacent to the limit block 202, and the other spring block 203 is fixed to the telescopic end of the telescopic cylinder 204.

[0045] In this technical solution, the specific arrangement of the limiting block 202 and the spring block 203 enables stable clamping of the phone case. The two limiting blocks 202 are arranged adjacently to restrict the horizontal movement of the phone case, ensuring its positional accuracy during the film-removing process. One spring block 203 is adjacent to the limiting block 202; through the elasticity of the spring, it can adapt to phone cases of different sizes, providing appropriate clamping force and preventing damage to the phone case. The other spring block 203 is fixed to the telescopic end of the telescopic cylinder 204. The telescopic movement of the cylinder 204 pushes the spring block 203 to apply pressure to the phone case, further enhancing the clamping effect and ensuring smooth film-removing operation. Through this design, the film-removing machine can adapt to various specifications of phone cases, improving the equipment's versatility and practicality.

[0046] For example, see Figure 1 As shown, the film-forming block 30111 is made of soft non-metallic materials such as soft silicone or polyurethane (PU). The film-forming block 30111 is tilted and has several serrated grooves at the bottom.

[0047] In this technical solution, the film-lifting block 30111 is made of a soft material with good flexibility and wear resistance. When in contact with the protective film inside the phone case, it effectively avoids scratches or damage to the phone case surface. The inclined design of the film-lifting block 30111 creates an angle when in contact with the protective film, facilitating the lifting of the film from inside the phone case. The serrated groove at the bottom increases the friction between the film-lifting block 30111 and the protective film, further improving the film-lifting effect. In actual operation, the position and force of the film-lifting block 30111 can be adjusted by the lifting block 30106, ensuring the accuracy and stability of the film-lifting process.

[0048] For example, see Figures 1-2 As shown, the electric gripper 30204 is fixed to one side of the unloading robot 502.

[0049] In this technical solution, the unloading robot 502 moves the electric gripper 30204 to the area where the protective film has been lifted. The electric gripper 30204, through precise gripping action, firmly grasps the edge of the lifted protective film. Then, the unloading robot 502 slowly moves to directly above the waste bin 303, completing the film-tearing operation during the movement. Finally, the electric gripper 30204 opens to place the protective film into the waste bin 303. Furthermore, the coordinated work of the electric gripper 30204 and the unloading robot 502 achieves a seamless connection between film peeling and unloading of the phone case, further improving the automation and efficiency of the entire film peeling process.

[0050] For example, see Figure 1 and Figure 4 As shown, the adjusting plate 30107 is provided with an arc-shaped slot 30108, one end of the connecting block 30109 is hinged to the lifting block 30106, and the other end is provided with a connecting rod 30110 extending into the arc-shaped slot 30108.

[0051] In this technical solution, the arc-shaped slot 30108 on the adjusting plate 30107 is uniquely designed and cooperates with the connecting rod 30110 on the connecting block 30109 to achieve flexible adjustment of the film-lifting block 30111 in the vertical and horizontal directions. By adjusting the height of the lifting block 30106, the connecting rod 30110 slides within the arc-shaped slot 30108, thereby driving the film-lifting block 30111 to contact the protective film inside the phone case at different angles and positions. This design not only improves the flexibility of film lifting but also ensures that the film-lifting block 30111 can perform precise film lifting operations for phone cases of different shapes and sizes, further enhancing the adaptability and stability of the film-peeling machine. In practical applications, this flexible adjustment mechanism greatly improves the efficiency and accuracy of film-peeling operations.

[0052] Working Principle: When using this fully automatic film-removing machine for mobile phone cases, the power switch 102 and air supply switch 103 control the power supply and air supply connection. Then, the feeding conveyor belt 401 transports the mobile phone case to be peeled to the feeding robot 402. The feeding robot 402 grips the mobile phone case and places it in the positioning device 200. The positioning device 200, through the cooperation of the limit block 202 and the spring block 203, stably clamps the mobile phone case, ensuring its accurate position during the film-removing process. Then, the feeding robot 402 picks up the positioned mobile phone case and places it on the slider 30102. The slider 30102 moves the mobile phone case along the slide rail 30101 until it stops directly below the film-removing block 30111. The film-removing mechanism 301 then starts working, and the lifting motor 30105 drives the lifting block 30106 to move up and down. The process continues until the film-lifting block 30111 presses the protective film firmly. At this point, the slider 30102 continues to move, and the film-lifting block 30111 contacts the protective film inside the phone case with its serrated groove at the bottom, using friction to rub the film off from the inside of the phone case. At the same time, the electric gripper 30204 of the film-tearing mechanism 302, driven by the unloading robot 502, moves precisely to the rubbed protective film and firmly grasps the edge of the film through precise clamping action. Then, the unloading robot 502 drives the electric gripper 30204 to slowly move to the top of the waste box 303, completing the film-tearing operation during the movement. Finally, the protective film is placed into the waste box 303. Finally, the unloading robot 502 uses the suction cup 503 to pick up the phone case after the film is peeled off and place it on the unloading conveyor belt 501, which moves the phone case to the next process. Throughout the entire film-removing process, the feeding device 400 and the unloading device 500 work together to achieve automatic loading and unloading of phone cases, further improving production efficiency. This film-removing machine features an advanced design, compact structure, and ease of use. It can efficiently and stably remove the protective film from inside phone cases while maintaining a clean working environment, providing users with a better experience.
