[0072] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0073] Please refer to Figure 1 , an embodiment of the present application provides a film tearing mechanism 100 for tearing the film on a workpiece, which includes a transfer assembly 10, a clamping assembly 20, and a rolling assembly 30.

[0074] Please refer to Figure 1 and Figure 2The transfer assembly 10 is connected to the clamping assembly 20 and the rolling assembly 30 respectively. The clamping assembly 20 includes a fixed clamping member 21, a movable clamping member 22 and a clamping driving member 23. The fixed clamping member 21 is fixedly connected to the transfer assembly 10, and the movable clamping member 22 is rotatably connected to the transfer assembly 10. The movable clamping member 22 is used to push the film body adhered to the workpiece under the drive of the transfer assembly 10 so that part of the film body is tilted. The clamping driving member 23 is arranged on the transfer assembly 10 and connected to the movable clamping member 22. The rolling assembly 30 includes a rotating drive member 31 and a rolling member 32. The rotating drive member 31 and the clamping drive member 23 are arranged at intervals in the transfer assembly 10. The rolling member 32 is connected to the rotating drive member 31. The rolling member 32 is abutted against the tilted film body under the drive of the transfer assembly 10, and rotates under the drive of the rotating drive member 31 to move the tilted film body further away from the workpiece; wherein, the clamping drive member 23 drives the movable clamping member 22 to rotate to rotate close to the fixed clamping member 21, so that the movable clamping member 22 abuts against the film body after being moved by the rolling member 32 to the fixed clamping member 21. Exemplarily, the clamping drive member 23 can be a cylinder, and the rotating drive member 31 can be a motor. wherein, the material of the rolling member 32 is a flexible material, such as urethane, and the rolling member 32 is in flexible contact with the workpiece and the film body to avoid excessive thrust of the rolling member 32 and damage to the workpiece and the film body.

[0075] When the above-mentioned film tearing mechanism 100 is in operation, the transfer component 10 first drives the movable clamping member 22 to push the film body adhered to the workpiece so that the corners of the film body are lifted up, and then the transfer component 10 drives the rolling member 32 to abut against the lifted film body and the workpiece, so that the rolling member 32 rotates under the drive of the rotating driving member 31 to move the lifted film body, so that the lifted angle of the film body becomes larger to further separate from the workpiece, and finally the clamping driving member 23 drives the movable clamping member 22 to rotate to approach the fixed clamping member 21, so that the movable clamping member 22 abuts against the film body after being moved by the rolling member 32 to the fixed clamping member 21, and the transfer component 10 drives the fixed clamping member 21 and the movable clamping member 22 to tear off the film body, so as to quickly tear off the film body and improve the film tearing efficiency.

[0076] See also Figure 1 and Figure 2 In some embodiments, the movable clamping member 22 includes a rotating body 221, a clamping body 222 and a pushing body 223. The rotating body 221 is rotatably connected to the transfer assembly 10, and one end of the rotating body 221 is connected to the clamping driving member 23. The clamping body 222 is inclined relative to the extension direction of the rotating body 221 and is connected to the other end of the rotating body 221. The clamping body 222 pushes the film body to the fixed clamping member 21 under the drive of the rotating body 221. The pushing body 223 is arranged on the side of the clamping body 222 away from the fixed clamping member 21 and is detachably connected to the clamping body 222. The pushing body 223 is used to push part of the film body to rise up under the drive of the transfer assembly 10.

[0077] In this way, by setting the clamping body 222 to be inclined with respect to the extending direction of the rotating body 221, the pushing body 223 connected to the clamping body 222 is also inclined with respect to the extending direction of the rotating body 221, so that there is a sufficiently large clearance space between the clamping body 222 and the pushing body 223 and the fixed clamping member 21 and other components, which is convenient for the transfer assembly 10 to drive the pushing body 223 to stably push up a part of the film body on the workpiece. In addition, by setting the pushing body 223 and the clamping body 222 to be detachably connected, it is convenient to replace the damaged pushing body 223 due to long-term operation later.

[0078] Please refer to Figure 2 , in some embodiments, a plurality of anti-slip grooves 2221 are provided on the side of the clamping body 222 facing the movable clamping member 22, and the plurality of anti-slip grooves 2221 are uniformly arranged on the clamping body 222.

[0079] In this way, by providing a plurality of anti-slip grooves 2221 on the side of the clamping body 222 facing the movable clamping member 22, the friction force between the clamping body 222 and the film body when clamping the film body can be increased, which is convenient for the clamping assembly 20 to stably clamp the film body.

[0080] Please continue to refer to Figure 2 , in some embodiments, the fixed clamping member 21 includes a clearance body 211 and a fixed body 212. Both ends of the clearance body 211 are respectively connected to the transfer assembly 10 and the fixed body 212. In the direction from the side of the clearance body 211 adjacent to the movable clamping member 22 to the side of the clearance body 211 away from the movable clamping member 22, the cross-sectional area of the clearance body 211 is smaller than the cross-sectional area of the fixed body 212.

[0081] After the transfer assembly 10 drives the clamping assembly 20 to tear the film body from the workpiece, it is necessary for the clamping assembly 20 to release the torn film body. In this way, by setting the specific structure of the fixed clamping member 21 as described above, when clamping the film body, the fixed body 212 of the fixed clamping member 21 and the clamping body 222 respectively clamp both sides of the film body, and the clearance body 211 clears the clamped film body, so as to reduce the contact area between the film body and the fixed clamping member 21, which is convenient for the clamping assembly 20 to release the torn film body.

[0082] Please refer to Figure 2 , in some embodiments, an air blowing hole 2121 is provided on the side of the fixed body 212 facing the movable clamping member 22, and the air blowing hole 2121 is used to communicate with an external air source to blow air toward the torn film body.

[0083] In this way, by providing the air blowing hole 2121 as described above, when the clamping assembly 20 releases the torn film body, the air blowing hole 2121 blows air toward the torn film body under the drive of the external air source, so that the film body quickly drops to a preset position.

[0084] See also Figure 1 In some embodiments, the transfer assembly 10 includes a base 11 and a transfer member 12. The fixed clamping member 21, the clamping driving member 23 and the rotating driving member 31 are respectively fixedly connected to the base 11, and the movable clamping member 22 is rotatably connected to the base 11. The transfer member 12 is connected to the base 11, and the transfer member 12 drives the base 11 to drive the movable clamping member 22 and the rolling member 32 to move. Exemplarily, the transfer member 12 can be a manipulator.

[0085] In this way, by setting the transfer member 12 connected to the base 11, the transfer member 12 can drive the base 11, the clamping assembly 20 and the rolling assembly 30 to move synchronously, thereby driving the rolling assembly 30 to move the raised film body, and driving the clamping assembly 20 to clamp the moved film body and tear it off the workpiece.

[0086] See also Figure 1 and Figure 3 In some embodiments, the base 11 includes a base 111, a support member 112, and a linkage member 113. The base 111 is connected to the transfer member 12, the support member 112 is connected to the base 111, the fixed clamping member 21 and the clamping driving member 23 are arranged at intervals on the support member 112, the movable clamping member 22 is rotatably connected to the support member 112, the linkage member 113 is mounted on the support member 112 and connected to the support member 112, and the linkage member 113 is connected to the rotation driving member 31 for supporting the rotation driving member 31.

[0087] In this way, by setting the linkage member 113 mounted on the support member 112 and connected to the support member 112, the clamping assembly 20 connected to the support member 112 and the rolling assembly 30 connected to the linkage member 113 can be reasonably arranged to avoid interference between the clamping assembly 20 and the rolling assembly 30.

[0088] See also Figure 3 In some embodiments, the linkage member 113 includes a linkage body 1131, a guide body 1132 and an elastic body 1134. The linkage body 1131 is connected to the support member 112, and the guide body 1132 is movably arranged in the linkage body 1131 and is used to abut against the side of the linkage body 1131 away from the rotating driving member 31. One side of the connecting body 1133 is connected to the rotating driving member 31, and the other side of the connecting body 1133 is connected to an end of the guide body 1132 away from the linkage body 1131. The elastic body 1134 is sleeved on the guide body 1132, and the two ends of the elastic body 1134 elastically abut the linkage body 1131 and the connecting body 1133 respectively. Exemplarily, the elastic body 1134 can be a spring.

[0089] Thus, by setting the specific structure of the linkage member 113, when the transfer member 12 drives the rolling member 32 to abut against the film body and the workpiece through the linkage body 1131, the elastic body 1134 can be compressed by the linkage body 1131 to the connecting body 1133 under the guidance of the guiding body 1132, so that a flexible contact occurs between the rolling member 32 and the film body and the workpiece, avoiding damage to the workpiece and the film body. In addition, after the rolling member 32 is worn, the linkage member 113 can timely adjust the distance between the rolling member 32 and the film body and the workpiece, so that the rolling member 32 stably abuts against the workpiece and the film body.

[0090] Please continue to refer to Figure 3 , in some embodiments, the linkage body 1131 includes a linkage portion 1131a and a bearing portion 1131b. The linkage portion 1131a is connected to the support member 112, and the bearing portion 1131b is sleeved on one end of the guiding body 1132 away from the rotation driving member 31 and is connected to the linkage portion 1131a. Exemplarily, the bearing portion 1131b can be a linear bearing.

[0091] Thus, by sleeving the bearing portion 1131b on the guiding body 1132, the bearing portion 1131b can separate the guiding body 1132 and the linkage portion 1131a, avoiding direct contact between the linkage portion 1131a and the guiding body 1132, and enabling the guiding body 1132 to move stably relative to the linkage portion 1131a.

[0092] Please refer to Figure 4 , a film tearing device 200 provided by an embodiment of the present application includes a carrying device 201 and a film tearing mechanism 100. The carrying device 201 is disposed on one side of the film tearing mechanism 100 for carrying a workpiece with a film body attached thereto.

[0093] The working process of the above-mentioned film tearing device 200 is generally as follows:

[0094] First, the carrying device 201 carries the workpiece with the film body attached thereto, and the transfer member 12 drives the base 11 to drive the movable clamping member 22 to push against the film body adhered to the workpiece, so that the corners of the film body are lifted.

[0095] Then, the transfer member 12 drives the base 11 to drive the rolling member 32 to move closer to the workpiece, so that the rolling member 32 flexibly abuts against the lifted film body and the workpiece.

[0096] Next, the rolling member 32 rotates under the drive of the rotation driving member 31 to dial the lifted film body, so that the lifted angle of the film body becomes larger.

[0097] Finally, the clamping driving member 23 drives the movable clamping member 22 to rotate and approach the fixed clamping member 21. The movable clamping member 22 abuts against the film body that has been toggled by the rolling member 32 to the fixed clamping member 21 to clamp the film body to be torn off. Then, the transfer member 12 drives the fixed clamping member 21 and the movable clamping member 22 to move to tear off the film body, thereby realizing quickly tearing off the film body and improving the film tearing efficiency.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
