Description

Technical Field

[0001] The present application relates to the technical field of automatic film tearing, and in particular to a film tearing mechanism. Background Art

[0002] At present, when tearing off the film attached to the mobile phone frame, screen and other products, the film is usually clamped by a clamp, and then a motion mechanism such as a robotic arm drives the clamp to rotate along the trajectory of the film on the product and tear off the film. However, after the clamp completely tears off the film, the film is wound on the clamp, and it is necessary to manually use a blade to cut the wound film before the film can be removed from the clamp by the film removal claw, which affects the film tearing operation of subsequent products and further affects the film tearing efficiency. In addition, when cutting the wound film with a blade, it is easy to scratch the high-gloss surface of the clamp, which can easily cause the film to be damaged and remain on the product during the film tearing process, thereby affecting the film tearing yield.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0055] See also Figure 1 The embodiment of the present application provides a film tearing mechanism 100 for tearing off a film 200 attached to a product. The product may be a mobile phone frame, a mobile phone screen, etc. The film 200 may be attached to the product by electrostatic adsorption, adhesion, etc. For ease of understanding and explanation, the embodiment of the present application takes the mobile phone frame as the product and the film 200 attached to the outer wall of the product by adhesion as an example for explanation. Obviously, this is not a limitation of the embodiment of the present application.

[0056] See also Figure 1 and Figure 2 In this embodiment, the film tearing mechanism 100 includes a driving assembly 10 , a first clamping member 20 , a second clamping member 30 , a first supporting member 40 and a second supporting member 50 .

[0057] The driving component 10 can be set on a robotic arm (not shown) and move and rotate under the drive of the robotic arm; the first clamping member 20 and the second clamping member 30 are connected to the driving component 10 and are arranged opposite to each other. The first clamping member 20 and the second clamping member 30 can approach or move away from each other under the drive of the driving component 10 to clamp or release the film 200, and can tear off the film 200 under the drive of the driving component 10 when clamping the film 200. Since the film 200 is thin and fits the product more tightly, it is not conducive to direct clamping by the first clamping member 20 and the second clamping member 30. When tearing the film, the driving component 10 drives the first clamping member 20 and the second clamping member 30 to clamp the film head 210 of the film 200 and drive the film head 210 to move. The film head 210 tears the film 200 from the product during the movement. Since the first clamping member 20 and the second clamping member 30 can easily clamp the larger film head 210 and are not easy to separate from the film head 210, it is beneficial to improve the stability and efficiency of film tearing.

[0058] The first support member 40 is arranged on the first clamping member 20 and extends toward the second clamping member 30, and the first support member 40 has a first support portion 42; the second support member 50 is arranged on the second clamping member 30 and extends toward the first clamping member 20, and the second support member 50 has a second support portion 52. The first support portion 42 and the second support portion 52 are arranged opposite to each other, and the first support portion 42 and the second support portion 52 are used to move away from each other when the first clamping member 20 and the second clamping member 30 are close to each other to support the film 200 torn off by the first clamping member 20 and the second clamping member 30, and move towards each other when the first clamping member 20 and the second clamping member 30 are far away from each other to detach from the torn film 200.

[0059] During the film tearing process, the driving component 10 drives the first clamping member 20 and the second clamping member 30 to approach each other and clamp the film head 210. At this time, the first support portion 42 and the second support portion 52 are driven by the first clamping member 20 and the second clamping member 30 to move away from each other. The driving component 10 drives the first clamping member 20, the second clamping member 30, the first support member 40 and the second support member 50 to move and rotate along the trajectory of the film 200 on the product under the drive of the mechanical arm. The first clamping member 20 and the second clamping member 30 drive the film head 210 to move and tear the film 200 off the product. When the film 200 is torn off, it is wound around and supported on the first clamping member 20, the second clamping member 30, the first support member 40 and the second support member 50. The first supporting member 20 is on the second supporting member 50, and the back side of the film 200 contacts the first supporting member 42 and the second supporting member 52, and then the driving component 10 drives the first clamping member 20 and the second clamping member 30 to move away from each other and release the film head 210, and the first supporting member 42 and the second supporting member 52 are driven by the first clamping member 20 and the second clamping member 30 to move closer to each other and separate from the film 200. At this time, the film 200 can be gently pulled by the film stripping claw (not shown) to quickly remove the wound film 200 from the film tearing mechanism 100, thereby reducing the process of manually using a blade to cut the wound film 200, avoiding the situation where the blade scratches the film tearing mechanism 100, and is beneficial to improving the film tearing efficiency and the film tearing yield.

[0060] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the driving assembly 10 includes a driving member 11 and two fixing members 12. The driving member 11 is connected to the mechanical arm to move and rotate under the drive of the mechanical arm. The driving member 11 can be a clamping cylinder or a clamping motor. The two fixing members 12 are connected to the driving member 11 and are arranged at intervals. The driving member 11 can drive the two fixing members 12 to move closer to or away from each other. The two fixing members 12 are provided with mounting grooves 1221 arranged opposite to each other on one side. The first clamping member 20 and the second clamping member 30 are respectively clamped in the mounting grooves 1221 provided in the two fixing members 12, and the first clamping member 20 and the second clamping member 30 can be fixed in the corresponding mounting grooves 1221 by bolts (not shown). By providing installation grooves 1221 for clamping the first clamp 20 and the second clamp 30 on the two fixing members 12, it is convenient to quickly install the first clamp 20 and the second clamp 30, and the first clamp 20 and the second clamp 30 are positioned by the corresponding installation grooves 1221, which is beneficial to improve the accuracy of the first clamp 20 and the second clamp 30 facing each other.

[0061] In this embodiment, the two fixing members 12 each include a mounting block 121 and a connecting block 122. The mounting block 121 is connected to the driving member 11. The mounting block 121 is provided with a first mounting hole 1211, so that the mounting block 121 and the driving member 11 can be quickly fixed by bolts. The connecting block 122 is vertically arranged on the mounting block 121, and the side of the connecting block 122 close to the other fixing member 12 is flush with the side of the mounting block 121 close to the other fixing member 12. The mounting groove 1221 is provided on the side of the connecting block 122 close to the other fixing member 12, and the mounting groove 1221 is formed by The connecting block 122 extends from one end away from the corresponding mounting block 121 to the other end, so as to facilitate the first clamping member 20 and the second clamping member 30 to be inserted into the corresponding mounting groove 1221. A second mounting hole 1222 connected to the mounting groove 1221 is provided on the connecting block 122, and a connecting hole 211 corresponding to the second mounting hole 1222 is provided on the first clamping member 20 and the second clamping member 30, so as to facilitate the first clamping member 20 and the second clamping member 30 to be quickly fixed to the corresponding connecting block 122 by passing bolts through the second mounting hole 1222 and the connecting hole 211.

[0062] In this embodiment, the first clamping member 20 includes a first connecting portion 21 and a first clamping portion 22 provided on the first connecting portion 21, and the second clamping member 30 includes a second connecting portion 31 and a second clamping portion 32 provided on the second connecting portion 31. The first connecting portion 21 and the second connecting portion 31 are respectively connected to the two fixing members 12 of the driving assembly 10 and are arranged at intervals. The first connecting portion 21 and the second connecting portion 31 are specifically snapped into the mounting groove 1221 opened in the corresponding fixing member 12, and the connecting hole 211 is opened in the first connecting portion 21. On the second connecting part 31, the driving member 11 drives the first connecting part 21 and the second connecting part 31 to move closer to or away from each other through the two fixing members 12, the first clamping part 22 and the second clamping part 32 are arranged opposite to each other, the first clamping part 22 and the second clamping part 32 are used to clamp or release the film 200, the first supporting member 40 is arranged on the first connecting part 21 and the first supporting part 42 is located on the same side of the second clamping part 32, and the second supporting member 50 is arranged on the second connecting part 31 and the second supporting part 52 is located on the same side of the first clamping part 22. By providing the first clamping portion 22 and the second clamping portion 32 to clamp or release the film 200, and providing the first support portion 42 and the second support portion 52 on the same side of the second clamping portion 32 and the same side of the first clamping portion 22, respectively, it is beneficial to improve the compactness of the overall structure of the film tearing mechanism 100, and can make the mutual movement relationship between the first support portion 42 and the second support portion 52 opposite to the mutual movement relationship between the first clamping portion 22 and the second clamping portion 32, so that the first support portion 42 and the second support portion 52 can support the wound film 200 when the first clamping portion 22 and the second clamping portion 32 clamp the film head 210, and can also facilitate the first support portion 42 and the second support portion 52 to detach from the wound film 200 when the first clamping portion 22 and the second clamping portion 32 hold the film head 210.

[0063] In this embodiment, the first connection part 21 and the second connection part 31 are both roughly plate-shaped, and the first clamping part 22 and the second clamping part 32 are both roughly long strips. The sides of the first clamping part 22 and the second clamping part 32 that are close to each other protrude from the first connection part 21 and the second connection part 31 respectively. When the first connection part 21 and the second connection part 31 are close to each other, the first clamping part 22 and the second clamping part 32 move toward each other and abut against each other under the drive of the first connection part 21 and the second connection part 31 respectively. Since it is difficult to process the side of the first clamping member 20 and the second clamping member 30 close to each other to be completely flat when processing the first clamping member 20 and the second clamping member 30, when the first connecting portion 21 and the second connecting portion 31 are close to and abut against each other, the defects generated during the processing of the first connecting portion 21 and the second connecting portion 31 may make it impossible for the first clamping portion 22 and the second clamping portion 32 to abut against each other, thereby affecting the clamping accuracy of the first clamping portion 22 and the second clamping portion 32. By setting the side of the first clamping portion 22 and the second clamping portion 32 close to each other to protrude from the first connecting portion 21 and the second connecting portion 31 respectively, the first connecting portion 21 and the second connecting portion 31 will no longer abut against each other when they are close to each other, and the normal abutment of the first clamping portion 22 and the second clamping portion 32 will not be affected by the defects generated during the processing of the first connecting portion 21 and the second connecting portion 31, thereby improving the clamping accuracy of the first clamping portion 22 and the second clamping portion 32 and facilitating the processing of the first clamping member 20 and the second clamping member 30.

[0064] In the present embodiment, at least one of the sides of the first clamping portion 22 and the second clamping portion 32 close to each other is provided with a clamping protrusion 221. The clamping protrusion 221 may be multiple and arranged at intervals. The clamping protrusion 221 may specifically be serrated. By providing the clamping protrusion 221, the friction between the first clamping portion 22 and the second clamping portion 32 and the film head 210 of the film 200 can be increased, which is beneficial to improve the stability when tearing the film. In addition, since the contact area between the clamping protrusion 221 and the film head 210 is small, when the first clamping portion 22 and the second clamping portion 32 move away from each other, it is convenient to quickly separate the first clamping portion 22 and the second clamping portion 32 from the film head 210.

[0065] Please refer to Figure 4 and Figure 5In this embodiment, the first clamping part 22 and the second clamping part 32 have an avoidance arc surface 222 on the side facing away from each other. The avoidance arc surface 222 is used to avoid the film 200 when the first support part 42 and the second support part 52 support the torn film 200. After the film 200 is torn off, the first clamping part 22 and the second clamping part 32 clamp the film head 210 to form a fulcrum, and the first support part 42 and the second support part 52 support the wound film 200 and form another two fulcrums. By providing the avoidance arc surface 222 on the side facing away from each other of the first clamping part 22 and the second clamping part 32, the contact with the wound film 200 can be avoided or reduced, so that a certain moving space can be reserved for the first clamping part 22 and the second clamping part 32, and it is conducive to quickly removing the wound film 200 from the film tearing mechanism 100 when the first clamping part 22 and the second clamping part 32 release the film head 210.

[0066] Please refer again Figure 2 and Figure 3 In this embodiment, the first support member 40 also includes a first extension portion 41 provided at the first connection portion 21 and extending toward the second connection portion 31, and the first support portion 42 is vertically provided at one end of the first extension portion 41 away from the second connection portion 31. The second support member 50 also includes a second extension portion 51 provided at the second connection portion 31 and extending toward the first connection portion 21. The first extension portion 41 and the second extension portion 51 are parallel to each other, and the second support portion 52 is vertically provided at one end of the second extension portion 51 away from the first connection portion 21. By arranging the first extension portion 41 and the second extension portion 51 to be parallel to each other, interference between the first extension portion 41 and the second extension portion 51 during movement can be avoided; by arranging the first support portion 42 vertically at the end of the first extension portion 41 away from the second connection portion 31, and arranging the second support portion 52 vertically at the end of the second extension portion 51 away from the first connection portion 21, the mutual movement relationship between the first support portion 42 and the second support portion 52 can be opposite to the mutual movement relationship between the first clamping portion 22 and the second clamping portion 32, thereby facilitating the first support portion 42 and the second support portion 52 to support and detach from the wound film 200.

[0067] In this embodiment, the first connection part 21 and the second connection part 31 are both provided with a plug hole 212, and the first extension part 41 and the second extension part 51 are respectively inserted into the plug holes 212 provided in the first connection part 21 and the second connection part 31, so as to facilitate the connection of the first support member 40 and the second support member 50 with the first clamping member 20 and the second clamping member 30. By setting the first support member 40 and the first clamping member 20 as a split structure, and setting the second support member 50 and the second clamping member 30 as a split structure, it is convenient to process and assemble the first clamping member 20, the second clamping member 30, the first support member 40 and the second support member 50.

[0068] In some other embodiments, the first support member 40 and the first clamping member 20 may be processed into an integral structure, and the second support member 50 and the second clamping member 30 may be processed into an integral structure, which is not specifically limited in the embodiments of the present application.

[0069] In this embodiment, the first connection portion 21 is provided with an avoidance groove 213 for avoiding the second extension portion 51, and the second connection portion 31 is provided with an avoidance notch 311 for avoiding the first extension portion 41. The avoidance groove 213 is located between the first clamping portion 22 and the first extension portion 41, and the avoidance notch 311 is located on the side of the second extension portion 51 away from the second clamping portion 32. By providing the avoidance groove 213 and the avoidance notch 311, it is possible to avoid interference with the second connection portion 31 and the first connection portion 21 respectively when the first extension portion 41 and the second extension portion 51 move relative to each other, and it is beneficial to improve the compactness of the overall structure of the film tearing mechanism 100.

[0070] In some other embodiments, by adjusting the positions of the first extension portion 41 and the second extension portion 51, an avoidance notch 311 for avoiding the second extension portion 51 may be opened on the first connection portion 21, and accordingly, an avoidance groove 213 for avoiding the first extension portion 41 may be opened on the second connection portion 31. The embodiments of the present application do not specifically limit this.

[0071] Please refer to Figure 4 and Figure 5 In this embodiment, the first support portion 42 and the second support portion 52 have a support arc surface 421 on the side facing away from each other for supporting the torn film 200. By providing the support arc surface 421 to support the torn film 200, the support area of ​​the film 200 can be increased, thereby facilitating the improvement of the stability of supporting the torn film 200. In addition, when the torn film 200 is wound and supported on the first clamping portion 22, the second clamping portion 32, the first support portion 42 and the second support portion 52, the support arc surface 421 provided on the first support portion 42 and the second support portion 52 can make the wound film 200 roughly cylindrical, and the wound film 200 is wound into a cylinder. The shaped film 200 can reserve a certain amount of moving space for the first clamping portion 22 and the second clamping portion 32, thereby facilitating the first clamping portion 22 and the second clamping portion 32 to move away from each other to loosen the film head 210. In addition, the film 200 wound into a cylindrical shape has a stable structure, and is not easily deformed by the movement of the first support portion 42 and the second support portion 52 when the first support portion 42 and the second support portion 52 are separated from the film 200, thereby facilitating the rapid removal of the wound film 200 from the film tearing mechanism 100.

[0072] Please refer again Figure 2 and Figure 3In this embodiment, a supporting protrusion 4211 is convexly provided on the supporting arc surface 421. There may be a plurality of supporting protrusions 4211 which are spaced apart on the supporting arc surface 421. By providing the supporting protrusions 4211, the wound film 200 is supported at multiple points. The contact area with the film 200 can be reduced without reducing the stability of supporting the film 200, thereby facilitating the rapid separation of the first supporting portion 42 and the second supporting portion 52 from the wound film 200.

[0073] The film-tearing mechanism 100 of the embodiment of the present application performs the following process for film-tearing:

[0074] The driving member 11 drives the first clamping member 20 and the second clamping member 30 to approach each other through the two fixing members 12, and the first clamping portion 22 and the second clamping portion 32 clamp the membrane head 210;

[0075] The driving member 11, driven by the mechanical arm, drives the first clamping member 20, the second clamping member 30, the first support member 40 and the second support member 50 to move and rotate along the trajectory of the film 200 on the product through the two fixing members 12. The first clamping portion 22 and the second clamping portion 32 drive the film head 210 to move and tear the film 200 off the product. When the film 200 is torn off, it is wound and supported on the first clamping portion 22, the second clamping portion 32, the first support portion 42 and the second support portion 52. The first clamping portion 22 and the second clamping portion 32 clamp the film head 210 to form a fulcrum, and the first support portion 42 and the second support portion 52 support the wound film 200 and form another two fulcrums.

[0076] The driving member 11 drives the first clamping member 20 and the second clamping member 30 to move away from each other and reach a semi-open state through the two fixing members 12, and the first clamping portion 22 and the second clamping portion 32 release the film head 210. The first supporting member 40 and the second supporting member 50, driven by the first clamping member 20 and the second clamping member 30, make the first supporting portion 42 and the second supporting portion 52 move toward each other and separate from the wound film 200.

[0077] The rolled film 200 is removed from the film tearing mechanism 100 by gently pulling the film 200 with the film stripping claws.

[0078] In summary, the film tearing mechanism 100 of the embodiment of the present application drives the first clamping member 20 and the second clamping member 30 to move closer to or away from each other by setting a driving component 10, so as to clamp the film 200 and tear the film 200 off the product. By setting a first support member 40 and a second support member 50 connected to the first clamping member 20 and the second clamping member 30 respectively, and setting the first support member 40 and the second support member 50 to have a first support portion 42 and a second support portion 52 respectively, and the first support portion 42 and the second support portion 52 are arranged opposite to each other, when the first clamping member 20 and the second clamping member 30 clamp and tear the film 200 off the product, the first support portion The first supporting part 42 and the second supporting part 52 can move away from each other to support the torn and rolled-up film 200. When the first clamping member 20 and the second clamping member 30 release the torn-up film 200, the first supporting part 42 and the second supporting part 52 can move toward each other to separate from the torn-up film 200, thereby allowing the rolled-up film 200 to be quickly removed from the film tearing mechanism 100 without the need to manually use a blade to cut the rolled-up film 200, thereby reducing the process of manually using a blade to cut the rolled-up film 200, and avoiding the situation in which the blade scratches the film tearing mechanism 100 and causes the film 200 to be damaged and remain on the product, thereby facilitating improving the film tearing efficiency and the film tearing yield.
