For example, before assembling the mobile phone case, it is necessary to perform a film tearing treatment on the mobile phone case. The film tearing treatment often requires the use of a special film tearing device to tear off its protective film. After the film tearing mechanism in the film tearing device tears off a protective film, it is necessary to remove the waste film and then perform the film tearing step on the next component. In the related art, after the film tearing mechanism of the film tearing device tears off the film, the film is likely to remain on the film tearing mechanism, affecting the subsequent film tearing effect.

[0034] Referring to Figure 1 、 Figure 2 and Figure 10 , the film tearing device 100 according to an embodiment of the present utility model has an initial position 105, a film throwing position 106, and a brushing position 107. The brushing position 107 is located between the initial position 105 and the film throwing position 106. The film tearing device 100 includes a film tearing platform 101, a film tearing mechanism 201, a blowing mechanism 202, and a brush 203. The film tearing platform 101 is used to place the workpiece to be film torn. The film tearing mechanism 201 is used to clamp the film on the workpiece, and the film tearing mechanism 201 can move between the initial position 105, the film throwing position 106, and the brushing position 107. The blowing mechanism 202 is used to blow air on the film tearing mechanism 201 when the film tearing mechanism 201 moves to the film throwing position 106. The brush 203 is located at the brushing position 107, and the brush 203 is used to brush the film tearing mechanism 201 when the film tearing mechanism 201 moves from the film throwing position 106 to the initial position 105. The film tearing device 100 according to an embodiment of the present utility model adds a blowing mechanism 202 on the basis of the brush 203. After the film tearing mechanism 201 tears off the film at the initial position 105, it moves to the film throwing position 106, and the blowing mechanism 202 is used to blow air on the film tearing mechanism 201 to loosen and partially remove the residual film. The film tearing mechanism 201 will pass through the brushing position 107 when moving from the film throwing position 106 to the initial position 105, and the brush 203 located at the brushing position 107 will brush the film tearing mechanism 201 to further remove the waste film on it, so as to improve the subsequent film tearing effect of the film tearing mechanism 201.

[0035] It should be noted that in some embodiments of the present utility model, the film tearing device 100 is used for the mobile phone case assembly platform, specifically for peeling off the protective film on the mobile phone case. The film tearing device 100 according to an embodiment of the present utility model can also be used for the protective film on the flexible circuit board, the release paper on the parts, or other fields that require a film tearing step.

[0036] It should be noted that in some embodiments of the present utility model, the film tearing mechanism 201 tears the film by generating relative movement between the clamped film and the workpiece. Specifically, it means that after the film tearing mechanism 201 clamps the film, it does not move, while the workpiece moves after being adsorbed by other components such as the manipulator 401 mentioned below. In this way, relative movement is generated, and the technical effect of film tearing can be achieved. This method is applicable when the film is located at the bottom layer of the workpiece. In some embodiments of the present utility model, after the workpiece is fixed on the film tearing platform 101, the film tearing mechanism 201 clamps the film and then moves to achieve the film tearing effect. This method is applicable when the film is located on the upper surface or side of the workpiece.

[0037] Reference Figure 2 and Figure 10 , in some embodiments of the present utility model, the brushing position 107 is horizontally located between the initial position 105 and the film throwing position 106. The initial position 105 and the brushing position 107 are at the same height in the vertical direction. The film tearing device 100 further includes a transmission mechanism 206. The transmission mechanism 206 is connected to the film tearing mechanism 201 and is used to drive the film tearing mechanism 201 to move. When the film tearing mechanism 201 moves from the initial position 105 to the film throwing position 106, the transmission mechanism 206 drives the film tearing mechanism 201 to rise to avoid the brushing position 107. When the film tearing mechanism 201 moves from the film throwing position 106 to the initial position 105, the transmission mechanism 206 drives the film tearing mechanism 201 to descend to pass through the brushing position 107. Such a design allows the film tearing mechanism 201 to move in a generally circular path, making the entire film tearing process smoother. There is no need to perform more steps for blowing and brushing to remove the film. Designing the brushing position 107 on the path from the film throwing position 106 back to the initial position 105 is considered because if the waste film brushed off by the brush 203 on the path from the initial position 105 to the film throwing position 106 Figure 1 and Figure 2 as shown may fall on the equipment, which is not conducive to cleaning the waste film.

[0038] Reference Figure 2 and Figure 11 , in some embodiments of the present utility model, the film tearing mechanism 201 has an upper clamping jaw 208 and a lower clamping jaw 209. The upper clamping jaw 208 and the lower clamping jaw 209 are used to clamp the film. The brush 203 has a brush hair portion 210. The brush hair portion 210 is arranged in the vertical direction. When the film tearing mechanism 201 is located at the brushing position 107, the upper end surface of the brush hair portion 210 is higher than the upper clamping jaw 208, and the lower end surface of the brush hair portion 210 is lower than the lower clamping jaw 209. Such a design enables the clamping parts of the upper clamping jaw 208 and the lower clamping jaw 209 to be completely brushed by the brush hair portion 210, improving the brushing effect.

[0039] It should be noted that, reference Figure 2 andFigure 11 In some embodiments of the present utility model, the upper jaw 208 and the lower jaw 209 are of the pointed jaw type. The jaws are provided with a serrated structure. The jaws can accurately hold the film, and the pointed clamping end also has a smaller occupied area. The serrated structure can increase the friction between the jaws and the film to prevent falling off during the clamping process.

[0040] Reference Figure 1 and Figure 2 In some embodiments of the present utility model, the transmission mechanism 206 includes a lifting module 211 and a translation module 212. The lifting module 211 is connected to the upper jaw 208 and the lower jaw 209. The translation module 212 is connected to the lifting module 211. The translation module 212 is used to drive the lifting module 211 to move horizontally, and the lifting module 211 is used to drive the upper jaw 208 and the lower jaw 209 to lift. It should be noted that reference Figure 2 In some embodiments of the present utility model, the lifting module 211 is connected to the finger cylinder 213. The finger cylinder is connected to the upper jaw 208 and the lower jaw 209 and enables them to have the functions of clamping and opening. The finger cylinder 213 has advantages such as large clamping force and compact structure.

[0041] Reference Figure 2 and Figure 10 In some embodiments of the present utility model, the blowing mechanism 202 has an air outlet 207. The air outlet 207 is arranged to face both the brushing position 107 and the film throwing position 106 at the same time, and the brushing position 107 is closer to the air outlet 207 than the film throwing position 106. In this way, the blowing mechanism 202 can simultaneously have the functions of purging the brush 203 and the film tearing mechanism 201, and purging the brushing position 107 can blow the residual film on the brush 203 towards the film throwing position 106 so that they are jointly Figure 1 collected by the waste outlet 103 shown in

[0042] It should be noted that reference Figure 2 In some embodiments of the present utility model, the blowing mechanism 202 uses a connected adjustable blowing pipe. When it is necessary to blow air to the film tearing mechanism 201, the air outlet 207 of the blowing pipe can be aligned with the part of the film tearing mechanism 201 with residual film. The adjustable blowing pipe also makes it more convenient for the air outlet 207 to face the brushing position 107 and the film throwing position 106 at the same time.

[0043] Reference Figure 1, in some embodiments of the present utility model, the film tearing device 100 further includes a waste treatment assembly 102. The waste treatment assembly 102 has a waste opening 103. The waste opening 103 is adjacent to the brush 203 and is located below the film throwing position 106, and the waste opening 103 is arranged upward. The waste opening 103 facilitates the treatment of the waste film generated after film tearing. After the film tearing mechanism 201 tears off the film and moves to the film throwing position 106, it is located above the waste opening 103. Loosening the clamping structure can cause the film to fall into the waste opening 103 to complete collection. Moreover, the waste opening 103 is adjacent to the brush 203, and the waste film brushed off by the brush 203 can also fall into the waste opening 103 to complete collection. In this way, the waste films processed by the two film removing mechanisms are collected by one waste opening 103, optimizing the overall structure.

[0044] Reference Figure 1 , in some embodiments of the present utility model, the waste treatment assembly 102 further includes a first adsorption mechanism 104. The first adsorption mechanism 104 is communicated with the waste opening 103, and the first adsorption mechanism 104 is used to pump air out of the waste opening 103. The suction force generated by the first adsorption mechanism 104 on the waste opening 103 further promotes the film to fall into the waste opening 103, and draws the waste film adhered near the waste opening 103 into the interior of the waste treatment assembly 102, preventing the waste film from accumulating near the waste opening 103 and affecting the collection and treatment of the waste film.

[0045] Reference Figures 1 to 3 , in some embodiments of the present utility model, the film tearing device 100 further includes a translation mechanism 302. The translation mechanism 302 is installed on the film tearing platform 101. The translation mechanism 302 has a first surface 204 for placing the workpiece. The translation mechanism 302 is used to drive the workpiece to move along the plane direction of the first surface 204. A first air inlet 205 is opened on the first surface 204. The film tearing device 100 further includes a second adsorption mechanism 301. The second adsorption mechanism 301 is connected to the first air inlet 205 to pump air to adsorb the workpiece on the first surface 204. Such a design can adjust the position of the workpiece through the translation mechanism 302 to facilitate the film tearing mechanism 201 to better clamp the film, or enable the manipulator 401 to better clamp or adsorb the workpiece. Before the film tearing process, the workpiece needs to be placed on the translation mechanism 302 first. Therefore, by providing the first surface 204 and opening the first air inlet 205 on the translation mechanism 302, the workpiece can be adsorbed, thereby maintaining the stability of the workpiece, facilitating subsequent adsorption or movement of the workpiece, and Figure 2 and Figure 3 as can be seen, the first surface 204 protrudes relative to the other surfaces of the translation mechanism 302. In this way, only the first surface 204 can be subjected to high-precision surface treatment to maintain its flatness, reduce the area of the plane that requires high-precision machining, and improve the adsorption effect.

[0046] It should be noted that referring to Figure 2 , in some embodiments of the present invention, a plurality of first air inlets 205 are provided. Such a design can further improve the adsorption effect. In addition, in some embodiments of the present invention, the first air inlets 205 are also provided with suction cups 702 as shown in Figure 7 and Figure 8 to further improve the adsorption effect.

[0047] It should be noted that in some embodiments of the present invention, the first adsorption mechanism 104 and the second adsorption mechanism 301 are arranged in the same vacuum pumping device. This can simplify the structure and operation steps. During the working process, only one pumping device needs to be opened to achieve the pumping function for the first surface 204 and the waste outlet 103.

[0048] It should be noted that referring to Figure 3 , in some embodiments of the present invention, the translation mechanism 302 adopts a transmission mechanism of a cylinder piston rod. The power transmission of the cylinder is stable, reducing the shaking of the workpiece during movement. It also has the advantages of controllable speed, simple structure, low installation and maintenance costs, etc. In some embodiments of the present invention, a plurality of translation mechanisms 302 in multiple transmission directions as shown in Figure 3 are provided to meet the adjustment requirements in multiple directions. The translation mechanism 302 can also use transmission mechanisms such as guide rails and sliders, sprockets and chains, as long as it can achieve the movement of the workpiece in the plane direction of the first surface 204.

[0049] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 10, in some embodiments of the present utility model, the film tearing device 100 further includes a manipulator 401 and a transmission mechanism. The manipulator 401 is used to drive the workpiece away from the film tearing platform 101. The film tearing mechanism 201 is installed on the transmission mechanism 206, and the transmission mechanism 206 is used to drive the film tearing mechanism 201 to move. When the manipulator 401 drives the workpiece to move upward, the transmission mechanism 206 drives the film tearing mechanism 201 to clamp the film and move downward relative to the initial position 105. In this way, relative movement can be generated between the workpiece and the film tearing mechanism 201, and the film tearing mechanism 201 clamps the film, so the technical effect of film tearing can be achieved. This method is very convenient for tearing the film on the bottom surface of the workpiece, and there is no need to set a too large moving stroke for the film tearing mechanism 201. The manipulator 401, while driving the workpiece away from the film tearing platform 101, on the one hand satisfies the film tearing process, and on the other hand can also transport the workpiece that has completed film tearing to the next process, improving work efficiency. When the manipulator 401 drives the workpiece to move upward relative to the first surface 204, the transmission mechanism 206 drives the film tearing mechanism 201 to clamp the film and move downward relative to the initial position 105. In this way, the manipulator 401 and the film tearing mechanism 201 can move in opposite directions, so that the film and the workpiece move in opposite directions, making the film tearing process smoother. In some embodiments of the present utility model, the transmission mechanism 206 uses the connection form of a guide rail and a slider. The film tearing mechanism 201 is fixedly installed on the slider, and the guide rail is arranged along the normal direction of the first surface 204. In this way, the film tearing mechanism 201 can be moved along the normal direction of the first surface 204. Moreover, the transmission accuracy of the guide rail and slider is high, the occupied volume is small, and its size and position can be adjusted according to the structural distribution on the film tearing device 100. If the structure is relatively compact, a smaller specification of the guide rail and slider structure can be used, and the applicability is high. In some embodiments of the present utility model, the transmission mechanism 206 can also use methods such as a cylinder piston rod transmission or a sprocket and chain transmission.

[0050] It should be noted that, referring to Figure 4 and Figure 5 , in some embodiments of the present utility model, the manipulator 401 is installed in the upper half of the film tearing device 100 and grabs the workpiece from top to bottom. In this way, the space utilization rate can be improved, and the space occupied on the ground can be reduced. In some embodiments, in order to ensure the stability of the manipulator 401, the base of the manipulator 401 can also be installed on the ground.

[0051] It should be noted that, referring to Figure 4 and Figure 5 , in some embodiments of the present utility model, the manipulator 401 has a plurality of auxiliary arms 501 that can rotate and move, so as to achieve multi-angle transmission and clamping functions.

[0052] [[ID=IS17]]Referring to Figures 5 to 7, in some embodiments of the present utility model, the manipulator 401 includes a main body portion 601 and an adsorption portion 602. The adsorption portion 602 has a second surface 701 for adsorbing the workpiece. The second surface 701 is a plane. The adsorption portion 602 is mounted on the main body portion 601. The adsorption portion 602 is elastic. A second air inlet 703 is provided on the second surface 701. The manipulator 401 further includes a third adsorption mechanism 603. The third adsorption mechanism 603 is connected to the second air inlet 703 to pump air so that the second surface 701 adsorbs the workpiece. The adsorption method can avoid scratching the surface of the workpiece during film tearing and transportation, improve the quality of the workpiece. And in some embodiments of the present utility model, the film is located at the bottom surface of the workpiece. The manipulator 401 adsorbing the upper surface of the workpiece can also avoid interference with the process of tearing the film on the bottom surface of the workpiece by the film tearing mechanism 201, improving the film tearing quality. In some embodiments of the present utility model, clamping or other methods can also be used to drive and transport the workpiece as long as it does not affect the film tearing process on the surface of the workpiece. Setting the elastic adsorption portion 602 to adsorb the workpiece can avoid abrasion and scratching of the surface of the workpiece during the adsorption process by the manipulator 401, protecting the surface quality of the workpiece. Specifically, in some embodiments of the present utility model, the material of the adsorption portion 602 is soft rubber, specifically soft rubber materials such as silicone rubber, butyl rubber, polyurethane, etc., which can play a role in buffering and anti-abrasion.

[0053] It should be noted that referring to Figure 7 , in some embodiments of the present utility model, a plurality of protrusions are provided on the adsorption portion 602. By embedding the protrusions into a plurality of corresponding grooves provided on the main body portion 601, the adsorption portion 602 can be prevented from falling off during use. In some embodiments of the present utility model, the adsorption portion 602 can also be connected to the main body portion 601 by methods such as dispensing glue.

[0054] It should be noted that referring to Figure 7 and Figure 8 , in some embodiments of the present utility model, the manipulator 401 includes a suction cup 702 with a hollow structure. The suction cup 702 is embedded in the second surface 701. The suction cup 702 has a second air inlet 703. From the second air inlet 703 towards the inside of the manipulator 401, the outer edge dimension of the suction cup 702 gradually decreases. The suction cup 702 is elastic. The elastic suction cup 702 can further play a buffering role during the process of adsorbing the workpiece on the basis of the adsorption portion 602. And the shape of the suction cup 702 is designed such that from the second air inlet 703 towards the inside of the manipulator 401, the outer edge dimension gradually decreases, so that the suction cup 702 can deform better after contacting the workpiece, and the horn-shaped structure can be better squeezed.

[0055] It should be noted that referring to Figure 4 and Figure 9, in some embodiments of the present utility model, the film tearing device 100 further includes a film tearing platform 101 and a material taking mechanism 402. The film tearing platform 101 is used to place the workpiece, and the material taking mechanism 402 is used to take the workpiece to be film torn from the tray and place it on the film tearing platform 101. The material taking mechanism 402 further includes a camera module 901, and the camera module 901 is used to detect the position of the workpiece on the tray. The tray is not shown in the figure. The material taking mechanism 402 can improve the entire film tearing process. It can be seen from Figure 4 that, from left to right, first, the material taking mechanism 402 takes the workpiece to be film torn in the tray and places it on the film tearing platform 101. While the manipulator 401 takes away the workpiece on the film tearing platform 101, it completes the film tearing and sends the workpiece to the next process. The whole process is smooth and does not require too much reciprocating movement. If only the single manipulator 401 is used to complete the processes of placing and taking the material, the working efficiency is low. The camera module 901 on the material taking mechanism 402 can ensure that the workpiece is smoothly taken out of the tray. In some embodiments of the present utility model, the material taking mechanism 402 also takes out the workpiece by adsorption. The camera module is beneficial for the material taking mechanism 402 to accurately adsorb the required workpiece and improve the working efficiency.

[0056] In some embodiments of the present utility model, referring to Figure 1 , Figure 2 , Figure 4 and Figure 10 , the complete working process is as follows: The material taking mechanism 402 adsorbs the workpiece to be film torn in the tray and moves it to the film tearing platform 101. The translation mechanism 302 adsorbs the workpiece and drives the workpiece to move to a suitable position. The film tearing mechanism 201 clamps the film on the workpiece at the initial position 105. The manipulator 401 moves above the workpiece. While adsorbing the workpiece and moving upward, the film tearing mechanism 201 moves downward. While completing the film tearing, it comes to the position 1001 after film tearing. The manipulator 401 adsorbs the workpiece and goes to the next process. The film tearing mechanism 201 then moves upward to avoid the brushing position 107 and translates to the film throwing position 106, that is, above the waste material port 103. The blowing mechanism 202 blows air at the film tearing mechanism 201 to make the residual film fall off. The film tearing mechanism 201 then moves downward and returns to the initial position 105. During the return process, it passes through the brush 203 at the brushing position 107. The brush 203 further brushes the residual film on the film tearing mechanism 201 to make it fall off, and the film tearing process is completed.

[0057] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model. In addition, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
