[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0036] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature can include the direct contact between the first and second features, or can include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature has a lower horizontal height than the second feature.

[0038] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] Generally, for the convenience of tearing off the film material, the size of the film material attached to the surface of the film to be torn is generally larger than the size of the surface of the film product to which the film material is attached, so that the four sides of the film material extend out of the outside of the film product to be torn. Or to save materials, a part of the film material extends out of the outside of the film product to be torn. The above two attachment methods of the film material can facilitate tearing off the film material completely from the film product to be torn by pulling the part of the film material that extends out of the outside of the film product to be torn.

[0040] In view of this, this embodiment provides a film tearing device. This film tearing device can tear off the film material attached to the film product to be torn by pulling the part of the film material that extends out of the outside of the film product to be torn, so that the film product to be torn is suitable for assembly, reprocessing or use.

[0041] Please refer to Figures 1 to 5 , this film tearing device includes a carrier 1, a clamping mechanism 2 and a transfer mechanism (not shown in the figure). The carrier 1 is configured to fix the film product 100 to be torn. The clamping mechanism 2 includes a clamping plate 21, a clamping jaw 22 and a driving part 23. Among them, the clamping plate 21 has a clamping surface 211 that can face the film material 200 attached to the film product 100 to be torn; the clamping jaw 22 is hinged to the clamping plate 21, and the clamping jaw 22 has a clamping part 221. The clamping part 221 can cooperate with the clamping surface 211 to clamp the part of the film material 200 that extends out of the outside of the film product 100 after the clamping jaw 22 rotates; the driving part 23 is configured to drive the clamping jaw 22 to rotate. The transfer mechanism is configured to transfer the clamping mechanism 2.

[0042] With the above structure, during the film tearing operation, the carrier 1 fixes the film product 100 to be torn and exposes the film material 200 attached to the film product 100 to be torn. The transfer mechanism transfers the clamping mechanism 2 so that the clamping surface 211 of the clamping plate 21 faces the film material 200, and specifically makes the part of the film material 200 that extends out of the outside of the film product 100 extend into the space between the clamping part 221 and the clamping surface 211 of the clamping plate 21. Subsequently, the driving part 23 drives the clamping jaw 22 to rotate, so that the clamping jaw 22 rotates and cooperates with the clamping surface 211 to clamp the film material 200. Finally, the transfer mechanism transfers the clamping mechanism 2 again to tear off the film material 200. The above operation process can replace manual labor, improve the efficiency of the film tearing operation, and reduce the labor input cost.

[0043] During the process of the transfer mechanism tearing off the film material 200, its transfer movement is preferably along a specific path, and the path direction can be the length, width or diagonal direction of the film material 200, that is, starting from the position where the film material 200 is clamped by the clamping mechanism 2, moving towards the other end of the length, width or diagonal direction of the film material 200 with this position as one end, so as to gradually tear off the film material 200.

[0044] In this embodiment, the clamping mechanism 2 further includes a substrate 24 fixedly connected to the clamping plate 21, and the substrate 24 is fixed to the movable end of the transfer mechanism. The middle part of the clamping jaw 22 has a first hinge point 10 hinged to the clamping plate 21; one end of the clamping jaw 22 forms a clamping part 221, and the other end of the clamping jaw 22 has a second hinge point 20. The driving part 23 is a cylinder, the fixed end of the cylinder (i.e., the cylinder block) is hinged to the substrate 24, and the movable end of the cylinder (i.e., the shaft body of the cylinder) is hinged to the second hinge point 20 of the clamping jaw 22.

[0045] Please refer to Figure 2 and Figure 3 , the substrate 24 can be formed by fixedly connecting multiple components to stably place the clamping plate 21 and the cylinder. The structure of the substrate 24 can be specifically set based on its load-bearing capacity or on-site space layout requirements, etc. Its structure is not the technical key point of this case and is not limited here. In this embodiment, the substrate 24 is substantially perpendicular to the clamping plate 21 and is connected to one end of the clamping plate 21. The clamping jaw 22 is directly or through an intermediate member hinged to the other end of the clamping plate 21. The two ends of the clamping jaw 22 are respectively located on both sides of the clamping plate 21 (that is, the clamping surface 211 of the clamping plate 21 and the other surface opposite to the clamping surface 211) and extend. For example, it can be generally formed in an "L" shape. The end of the clamping jaw 22 extending to the clamping surface 211 forms a clamping part 221, and the other end is hinged to the movable end of the cylinder. The fixed end of the cylinder is hinged to the end of the substrate 24 away from the clamping plate 21, so that the cylinder and the clamping jaw 22 form a linkage mechanism. Through the telescopic movement of the cylinder, the clamping jaw 22 can swing a specific angle forward or backward to cooperate with the clamping plate 21 to clamp the film material 200 or release the film material 200. In addition, by adjusting the stroke of the cylinder, the opening and closing angle between the clamping jaw 22 and the clamping plate 21 can be adjusted, so as to facilitate clamping the film material 200 or enabling the film material 200 to smoothly enter between the clamping jaw 22 and the clamping plate 21.

[0046] Preferably, the clamping part 221 is provided with anti-slip lines, and the anti-slip lines are suitable for increasing the friction between the clamping part 221 and the film material 200 when clamping the film material 200, so as to prevent the film material 200 from slipping out between the clamping part 221 and the clamping plate 21 during the process of tearing off the film material 200. The anti-slip lines can be multiple convex lines arranged in parallel, and the extending direction of the convex lines is preferably perpendicular to the path direction of the transfer mechanism when tearing off the film material 200.

[0047] Since in this embodiment, the product 100 with the film to be torn is fixed in the jig for the film tearing operation, therefore, each time a film tearing operation is completed, it is necessary to move the product 100 with the film to be torn into and out of the jig. For this purpose, please refer to Figures 4 to 6 , in this embodiment, the clamping surface 211 of the clamping plate 21 may be provided with a first suction holding portion, and the first suction holding portion can suck and hold the product 100 with the film to be torn, so that the clamping plate 21 can be used as an actuator for transporting and transferring the product 100 with the film to be torn. By the transfer mechanism, the clamping mechanism 2 is transported to realize the movement of the product 100 with the film to be torn into and out of the jig.

[0048] Optionally, to form the above-mentioned first suction holding portion, a plurality of suction nozzles 25 may be penetrated through the clamping plate 21, and the plurality of suction nozzles 25 all extend to the clamping surface 211, so that the suction nozzles 25 suck and hold the product 100 with the film to be torn when forming a passage with the vacuum air source.

[0049] Moreover, since the first suction holding portion is provided on the clamping plate 21, the film tearing device can drive the clamping mechanism 2 to perform loading, film tearing and unloading operations through the transfer mechanism. To facilitate the rapid loading and unloading operations of the product 100 with the film to be torn, the film tearing device may further include a loading and unloading mechanism (not shown in the figure), and the loading and unloading mechanism is configured to store the products 100 with the film to be torn in a stacked manner, so as to realize the batch supply and transportation of the products 100 with the film to be torn and reduce the intervention frequency of manpower or other handling equipment. Depending on the specific contour shape of the product 100 with the film to be torn, the loading and unloading mechanism may be a basket or other mechanism with a vertically extending storage bin, etc., which is not specifically limited herein.

[0050] In this embodiment, the clamping surface 211 of the clamping plate 21 may further be provided with a second suction holding portion, and the second suction holding portion can suck and hold the part of the film material 200 extending outside the product 100 with the film to be torn. That is, before the clamping portion 221 of the clamping jaw 22 clamps the film material 200, the part of the film material 200 extending outside the product 100 with the film to be torn can be sucked and held in advance through the second suction holding portion, so that this part of the film material 200 adheres to the clamping surface 211, thereby ensuring that the film material 200 can be clamped when the clamping portion 221 of the clamping jaw 22 moves towards the clamping surface 211, and avoiding the film material 200 from interfering and contacting with other parts other than the clamping portion 221 in a swinging manner of the clamping jaw 22 and not entering between the clamping portion 221 and the clamping surface 211.

[0051] Optionally, please refer to Figure 5 and Figure 6 , the clamping plate 21 has an air passage 26 therein, and a plurality of air holes 27 communicating with the air passage 26, and the plurality of air holes 27 extend to the clamping surface 211 and form the second suction holding portion. When the air passage 26 is communicated with the vacuum air source, a negative pressure is formed at each air hole 27 to adsorb the film material 200.

[0052] Preferably, the arrangement area range of several air holes 27 is larger than the contour range of the clamping portion 221, so that when the second suction holding portion sucks the film material 200, the adjacent portions around the portion of the film material 200 clamped by the clamping portion 221 can be adsorbed together, preventing the clamping failure caused by the warping of the film material 200.

[0053] In this embodiment, the carrier 1 can also fix the film product 100 to be torn by vacuum suction, that is, it has a bearing surface that can suck the film product 100 to be torn, so as to facilitate controlling whether the carrier 1 fixes the film product 100 to be torn by switching the on-off of the vacuum air passage or suction nozzle and other structures configured on the carrier 1 and the vacuum air source. The switching action is rapid and reliable.

[0054] In this embodiment, the transfer mechanism can be selected from existing manipulators or multi-axis modules, etc., as long as it can meet the requirements of the transfer clamping mechanism, so the specific structure will not be described in detail.

[0055] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
