[0068] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0069] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centrally disposed element at the same time. When an element is considered to be "disposed" on another element, it may be directly disposed on the other element or there may be a centrally disposed element at the same time.

[0070] The term "perpendicular" is used to describe the ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular between the two components. For example, combined with numerical descriptions, perpendicularity can refer to the angle between two straight lines being between 90°±10°, perpendicularity can also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity can also refer to the angle between a straight line and a plane being between 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0072] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0073] Please also read Figure 1 and Figure 2One embodiment of the present application provides a film tearing device 100 for tearing off a protective film 92 on a workpiece 91. The film tearing device 100 includes a bracket 10, a film tearing assembly 20, a transmission assembly 30 and a guide assembly 40. The bracket 10 is used to support and connect the film tearing assembly 20, the transmission assembly 30 and the guide assembly 40. The film tearing assembly 20 is used to absorb and clamp the protective film 92 to separate the protective film 92 from the workpiece 91. The transmission assembly 30 is used to drive the clamping action of the film tearing assembly 20. The guide assembly 40 is used to drive the film tearing assembly 20 to move relative to the bracket 10.

[0074] The bracket 10 includes a first support member 11 and two second support members 12, and the two second support members 12 are arranged at intervals on both sides of the first support member 11 along the first direction X. An opening 13 is formed at one end of the two second support members 12 away from the first support member 11, and the film tearing assembly 20 is located between the two second support members 12 and extends from the opening 13 to facilitate contact with the protective film 92.

[0075] The film tearing assembly 20 includes a moving member 21 , an adsorption mechanism 22 and a clamping mechanism 23 . The moving member 21 is movably connected to the bracket 10 along a first direction X. Specifically, the moving member 21 is located between the two second support members 12 .

[0076] Please also read Figure 3 The adsorption mechanism 22 includes two adsorption members 221. The two adsorption members 221 are respectively connected to the moving member 21 at both ends of the second direction Y. The second direction Y is perpendicular to the first direction X. Each adsorption member 221 is rotatably connected to the moving member 21. Each adsorption member 221 is configured to adsorb the protective film 92 and drive the adsorbed portion of the protective film 92 to separate from the workpiece 91. The two adsorption members 221 are used to adsorb the two corners of the protective film 92 and separate the two corners from the workpiece 91.

[0077] Please also read Figure 4 The clamping mechanism 23 includes two clamping jaws 231, which are rotatably disposed at the two ends of the moving member 21 in the second direction Y. The rotation axis of the clamping jaws 231 is parallel to the rotation axis of the adsorbing member 221. Each clamping jaw 231 is configured to cooperate with an adsorbing member 221 to clamp the adsorbed portion of the protective film 92, so as to improve the stability of the film tearing assembly 20 clamping the protective film 92. The two clamping jaws 231 are used to cooperate with the two corners of the protective film 92.

[0078] Optionally, the rotation axis of the clamping jaw 231 and the rotation axis of the suction member 221 both extend along the first direction X.

[0079] When the above-mentioned film tearing device 100 is in use, the movable part 21 is first placed adjacent to one of the second supporting parts 12; then the two adsorption parts 221 are adsorbed on the two corners of the protective film 92, and the film tearing device 100 is in the first state; then the two adsorption parts 221 are rotated to separate the two corners from the workpiece 91, and the film tearing device 100 is in the second state; then the two clamping jaws 231 are rotated to make the two clamping jaws 231 cooperate with the corresponding two adsorption parts 221 to clamp the two corners, and the film tearing device 100 is in the third state; finally, the movable part 21 is driven toward the other second supporting part 12 to synchronously drive the adsorption part 221 and the clamping jaws 231 to move, thereby increasing the separation range of the protective film 92 from the workpiece 91, and then realizing the function of automatically tearing off the protective film 92 on the workpiece 91, which is beneficial to improving the film tearing efficiency.

[0080] It is understandable that, in the process of driving the movable member 21 toward another second support member 12 , the bracket 10 can also be driven by an external device to move in a direction away from the product to simulate the action of manual film tearing and reduce the risk of the protective film 92 breaking.

[0081] It can be understood that the number of groups of adsorbents 221 and clamps 231 can be but is not limited to two groups, and can also be three groups, four groups or five groups, etc., wherein the two outermost groups of adsorbents 221 and clamps 231 are used to cooperate with the two corners of the clamping protective film 92, and at least one group of adsorbents 221 and clamps 231 located in the middle is used to cooperate with the edge of the clamping protective film 92 between the two corners.

The moving member 21 moves relative to the bracket 10 along the first direction X to synchronously drive the adsorbing member 221 and the clamping jaw 231 to move, thereby increasing the separation range of the protective film 92 from the workpiece 91, thereby realizing the function of automatically tearing off the protective film 92 on the workpiece 91, which is conducive to improving the film tearing efficiency.

[0085] In some embodiments, the movable member 21 is provided with a sliding hole 211 extending along the third direction Z, and the first driving rod 24 passes through the sliding hole 211 so that the first driving rod 24 can move along the third direction Z under the limiting action of the hole wall of the sliding hole 211, thereby improving the stability of the first driving rod 24 moving along the third direction Z.

[0086] In some embodiments, each first connecting rod 25 includes two first rod bodies 251 spaced apart along the first direction X, one end of the two first rod bodies 251 is located on both sides of the adsorption member 221 and is respectively hinged to the adsorption member 221, and the other end of the two first rod bodies 251 is located on both sides of the moving member 21 and is respectively hinged to the first driving rod 24 to improve the stability of the transmission.

[0087] In some embodiments, the rotation angle of the adsorption member 221 is 45°±5°, so as to facilitate the separation of the protective film 92 from the workpiece 91 and reduce the risk of the protective film 92 being torn.

[0088] Optionally, the rotation angle of the adsorption member 221 may be 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, or 50°.

[0089] Please also read Figure 2 and Figure 5 In some embodiments, the film tearing assembly 20 further includes a first driving member 26 connected to the bracket 10. The first driving member 26 is a cylinder. The first driving member 26 has a first transmission end 261 that moves along the third direction Z, and the first transmission end 261 is connected to the first driving rod 24 to drive the first driving rod 24 to move along the third direction Z.

[0099] Please refer again Figure 1 In some embodiments, the number of the film tearing assemblies 20 is two, and the moving member 21 of each film tearing assembly 20 is located between the two second support members 12. The two film tearing assemblies 20 are used to absorb and clamp the two sides of the protective film 92. The transmission assembly 30 is used to synchronously drive the clamping action of the two film tearing assemblies 20. The guide assembly 40 is used to drive the two film tearing assemblies 20 to move relative to the bracket 10.

[0100] The two adsorption parts 221 of one film tearing assembly 20 are arranged opposite to the two adsorption parts 221 of the other film tearing assembly 20 along the first direction X. During use, the four adsorption parts 221 adsorb the four corners of the protective film 92 and separate the four corners from the workpiece 91, and then the corresponding four clamps 231 cooperate to clamp the four corners, and finally drive the two moving parts 21 to move toward each other, so as to synchronously drive the adsorption parts 221 and the clamps 231 to move, thereby increasing the separation range of the protective film 92 from the workpiece 91, thereby realizing the function of automatically tearing off the protective film 92 on the workpiece 91 and improving the efficiency of film tearing.

[0101] It should be noted that, as long as any group of adsorbents 221 arranged diagonally adsorbs the two corners of the protective film 92 and separates the two corners from the workpiece 91, the function of automatically tearing off the protective film 92 on the workpiece 91 can be achieved, thereby improving the success rate of film tearing.

[0102] It is understandable that in other embodiments, the number of the film tearing assemblies 20 is three, four, or five.
