[0038] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0039] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components.

[0042] Figure 1 It is a structural schematic diagram of a film tearing mechanism according to an embodiment of the present disclosure. Figure 2 It is a structural schematic diagram of a film tearing mechanism from another angle according to an embodiment of the present disclosure. Figure 3 It is a schematic diagram of the exploded structure of the film tearing mechanism according to one embodiment of the present disclosure.

[0043] like Figures 1 to 3 As shown, the present disclosure provides a film tearing mechanism, which may include components such as a mounting plate 100 , a suction module 200 , and a clamping module 300 .

[0044] The film tearing mechanism disclosed in the present invention can be fixed to a mechanical arm when in use, and can move in a straight line under the drive of the mechanical arm. Specifically, the mounting plate 100 of the film tearing mechanism can be fixed to the end of the mechanical arm, and the end of the mechanical arm can be a linear motion mechanism or a rotating mechanism installed on the linear motion mechanism.

[0045] The suction module 200 is mounted on the mounting plate 100, and is used to suck the film to be removed to the first position; specifically, the suction module 200 can be arranged to rotate relative to the mounting plate 100. In a preferred embodiment, the rotation axis of the suction module 200 when rotating relative to the mounting plate 100 is perpendicular to the mounting plate 100, and when the suction module 200 rotates to a preset position, the suction module 200 can be fixed to the mounting plate.

[0046] In the present disclosure, the suction module 200 includes a first drive device 210 and a vacuum assembly 220, wherein the first drive device 210 is configured to be rotatable relative to the mounting plate 100. In a specific embodiment, the first drive device 210 may be a cylinder, but those skilled in the art should know that the first drive device 210 may also be other linear motion mechanisms such as a hydraulic cylinder or an electric cylinder. A first threaded hole and a second threaded hole may be provided on the cylinder body of the cylinder. A central through hole and an arc-shaped hole are provided on the mounting plate 100, and the axis of the arc-shaped hole is the axis of the central through hole.

[0047] The first fixing screw passes through the central through hole of the mounting plate 100 and is screwed into the first threaded hole of the first driving device 210. The second fixing screw passes through the arc-shaped hole of the mounting plate 100 and is screwed into the second threaded hole of the first driving device 210, so that the first driving device 210 can rotate around the axis of the central through hole. At this time, the second fixing screw will slide in the arc-shaped hole. When the first driving device 210 rotates to the required position, continue to tighten the first fixing screw and the second fixing screw, so that the first driving device 210 is fixed to the mounting plate 100.

[0048] The vacuum assembly 220 is arranged on the first driving device 210, so that the first driving device 210 can drive the vacuum assembly 220 to move close to or away from the film. Accordingly, when the vacuum assembly 220 approaches the film, it can contact the handle of the film. At this time, when the vacuum assembly 220 is provided with vacuum, the handle of the film can be firmly sucked. Then, when the vacuum assembly 220 is away from the film, the film can be sucked to the first position, and in the first position, the clamping module 300 can clamp the handle of the film.

[0049] In a preferred embodiment, the film can be placed horizontally. Moreover, the vacuum assembly 220 includes a vacuum tube 221 and a bellows vacuum suction cup 222 connected to one end of the vacuum tube 221, wherein the vacuum tube 221 can be directly or indirectly fixed to the first driving device 210, for example, fixed to the piston rod of the cylinder, and the angle between the end plane of the bellows vacuum suction cup 222 and the axis of the vacuum tube 221 is an acute angle, preferably, the angle value of the acute angle is 60-80°, preferably, the angle value can be 69°, that is, the vacuum tube 221 has an angle of about 159° with the axis of the bellows vacuum suction cup 222, so that the setting of the bellows vacuum suction cup 222 at a specific angle can be more stable during the film suction operation.

[0050] The clamping module 300 is used to clamp the film located at the first position, and remove the film through the action of the clamping module 300; wherein the action of the clamping module 300 includes the action generated by the clamping module 300 being driven by the robot arm.

[0051] In a preferred embodiment, the clamping module 300 is connected to the mounting plate 100 via a second driving device 400, so that the driving force provided by the second driving device 400 can make the clamping module 300 approach or move away from the suction module 200. Accordingly, when the suction module 200 sucks the handle portion of the film from the initial position to the first position, the second driving device 400 drives the clamping module 300 away from the suction module 200 so that the clamping module 300 avoids the film; when the handle portion of the film is sucked to the first position, the second driving device 400 drives the clamping module 300 to approach the handle portion and make the handle portion located between the first claw 311 and the second claw 312. At this time, the clamping module 300 will be able to clamp the handle portion of the film.

[0052] In the present disclosure, the clamping module 300 is disposed on the mounting seat 500, and the mounting seat 500 is disposed on the second driving device 400. More preferably, the clamping module 300 is configured to be rotatable relative to the mounting seat 500, and when the clamping module 300 is rotated to a preset position, it can be fixed to the mounting seat 500. In the present disclosure, the rotation process of the clamping module 300 relative to the mounting seat 500 is similar to the rotation process of the suction module 200 relative to the mounting plate 100, and will not be repeated here.

[0053] The clamping module 300 includes a first claw 311 and a second claw 312, at least one of which can be driven so that the first claw 311 and the second claw 312 can approach or move away from each other, thereby clamping the handle of the film by the first claw 311 and the second claw 312. More specifically, one of the first claw 311 and the second claw 312 of the present disclosure can be driven by a third driving device 313. Specifically, the third driving device 313 can be a cylinder, the first claw 311 is fixed to the cylinder body of the third driving device 313, and the second claw 312 is fixed to the piston rod of the third driving device 313, so that the third driving device 313 drives the two claws to open or close.

[0054] The film tearing mechanism disclosed in the present invention can flexibly, economically and efficiently remove the film of the shorter handle portion in a limited space through the coordinated action of the suction module 200 and the clamping module 300. The handle portion is a handle without adhesive backing and can be used for the film clamped by the clamping module 300. Therefore, the film tearing mechanism disclosed in the present invention also solves the technical problem that the yield of film tearing cannot be guaranteed by the traditional method of adhesive tape or separate clamping. At the same time, the film is removed by adhesive tape. Since the tape is a consumable, it is cumbersome to replace, and its cost, efficiency and yield are all low.

[0055] Moreover, the suction module 200 disclosed in the present invention also has a vacuum feedback function, that is, the vacuum degree of the vacuum tube is used to determine whether the handle of the film is sucked up; when the handle of the film is normally sucked up, the clamping module 300 is controlled to clamp, and accordingly, the film can be ensured to be sucked up first and then clamped by the clamping claws, thereby improving the film tearing yield; and the film tearing mechanism disclosed in the present invention has no consumables and does not need to frequently replace and adjust the structure; it is highly efficient and has a yield of nearly 100%. Moreover, the relative position and angle of the suction module 200 and the clamping module 300 are adjustable, with a wide range of applications, simple debugging, and strong flexibility.

[0056] In addition, through the three driving devices of the film tearing mechanism disclosed in the present invention, the various components of the film tearing mechanism disclosed in the present invention move relatively independently, and the motion control is flexible and changeable. At the same time, the film tearing mechanism can be installed on the hollow rotating platform, and the angle of the film tearing mechanism can be programmably controlled. The film tearing has a wide range of applications and strong flexibility. At the same time, by replacing different suction cups or adjusting the position and angle of the suction module 200 and the clamping module 300, the film tearing requirements of products of different specifications in different occasions can be met.
