Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0046] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, 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, and thus should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality of" means two or more, and at least one means one, two or more, unless otherwise specifically defined.

[0047] During the process of battery pack manufacturing, especially for 3C batteries, 3C mainly refers to computer, communication, and consumer electronic products. Usually, it is necessary to pre-mount a film with two adhesive surfaces on the battery surface. When stacking batteries, the film spaces and bonds adjacent batteries. The film includes a film body and surface films respectively attached to the two adhesive surfaces of the film body. The surface films facilitate spacing the adhesive surfaces of the film body, avoiding misadhesion and facilitating storage, etc.

[0048] When mounting the film body onto the battery surface, it is necessary to first tear off the surface film on one side of the film body. Most of the devices for tearing off the surface film have overly complex structures, and the film tearing effect is not good, which affects the efficiency of subsequent attaching the film to the battery surface.

[0049] In addition, due to the different size specifications of batteries and films, conventional film tearing devices usually need to be adapted to different film tearing clips, and different devices or film tearing clips need to be replaced for different batteries.

[0050] In view of this, combined with Figures 1 to 7 This application provides a battery film tearing device in an embodiment, aiming to overcome at least one of the above technical problems.

[0051] Referring to Figures 1 to 7 A battery film tearing device is used to tear off the surface film to be torn of the film 6, and includes a handling mechanism 1, a suction platform 2, and a film pressing mechanism 3.

[0052] Among them, the handling mechanism 1 is used to adsorb and move the film 6. The suction platform 2 is used to carry the film 6 adsorbed by the handling mechanism 1, and the suction platform 2 can adsorb the surface film to be torn; the film pressing mechanism 3 is used to clamp the surface film to be torn relative to the suction platform 2, so as to tear off the surface film to be torn when the handling mechanism 1 moves the film 6 away from the suction platform 2.

[0053] Among them, it should be noted that:

[0054] Figure 1 Shows the state structure of the overall battery film tearing device before the film 6 is placed on the suction platform 2 by the handling mechanism 1.

[0055] Figure 2 Shows the state structure of the overall battery film tearing device when the film 6 is clamped by the film pressing mechanism 3 and the suction platform 2.

[0056] Figure 3 Shows the state structure of the overall battery film tearing device when tearing the film.

[0057] Figure 4 Shows the state structure of the overall battery film tearing device when the torn surface film is exported by the suction platform 2.

[0058] Figure 7 The structural schematic diagram of a film 6 is shown, where the film 6 includes a film body 60, a first surface film 61 on one side of the film body 60, and a second surface film 62 on the other side of the film body 60. The first surface film 61 and the second surface film 62 can be single-piece or multi-piece respectively according to needs, which will not be elaborated here.

[0059] It can be understood that the film to be torn is the first surface film 61 or the second surface film 62. The first surface film 61 and the second surface film 62 need to be reserved with a protruding structure, which needs to protrude outside the film body 60, and the protruding structures of the first surface film 61 and the second surface film 62 need to be misaligned for the film pressing mechanism 3 to grip relative to the adsorption platform 2, so as to ensure that when the first surface film 61 or the second surface film 62 needs to be torn off, after the film pressing mechanism 3 and the adsorption platform 2 grip the first surface film 61 or the second surface film 62, the handling mechanism 1 can move the other parts of the film 6.

[0060] Through the adsorption effect of the handling mechanism 1 and the adsorption platform 2, the movement and preliminary positioning of the film 6 are realized. Cooperating with the film pressing mechanism 3 to grip the film to be torn relative to the adsorption platform 2, the film to be torn can be torn off during the movement of the film 6 by the handling mechanism 1, so as to realize the rapid peeling of the film to be torn and synchronously move the film 6 to the next process, which is beneficial to simplifying the film tearing equipment of the film 6 and improving the film tearing effect and efficiency of the film 6. Using the adsorption effect can improve the adaptability to different specifications of the film 6 compared with using a film tearing clip to clamp the film 6 to be torn, etc.

[0061] In some embodiments, referring to Figures 1 to 4 , the battery film tearing device further includes a base frame 4 and a first driving component 5.

[0062] Among them, in this embodiment, the base frame 4 includes a base 41, a support plate 42, a mounting plate 43, and an end plate 44.

In this embodiment, there are two end plates 44, which correspond to the two support plates 42 one by one, and the adsorption platform 2 is arranged between the two end plates 44.

[0063] The adsorption platform 2 is rotationally connected to the base frame 4 through a first rotating shaft 22. The adsorption platform 2 includes a carrying state and a discharging state. In the carrying state, the adsorption platform 2 carries the film 6. In the discharging state, the adsorption platform 2 rotates to discharge the torn film.

[0064] In this embodiment, the first rotating shaft 22 is rotationally connected to the mounting plate 43. The first driving component 5 is connected to the base frame 4 and the adsorption platform 2. Referring to Figure 3 and Figure 4 , the first driving component 5 is configured to be able to drive the adsorption platform 2 to rotate to discharge the torn film on the adsorption platform 2.

A plurality of vacuum nozzles can be evenly distributed on the first adsorption surface 210 of the first vacuum suction cup 21 to improve the uniform effect of adsorbing adhesive films 6 of different specifications.

[0066] In some embodiments, referring to Figure 1 and Figure 4 , the handling mechanism 1 includes a second vacuum suction cup 10 and a handling robot. The second vacuum suction cup 10 can adopt a structure similar to that of the first vacuum suction cup 21, and the second vacuum suction cup 10 has a second adsorption surface 100 for adsorbing the adhesive film 6. Similarly, a plurality of vacuum nozzles can be evenly distributed on the second adsorption surface 100 of the second vacuum suction cup 10 to improve the uniform effect of adsorbing adhesive films 6 of different specifications.

[0067] It can be understood that the handling robot is not shown in the drawings. The handling robot can adopt a conventional material transfer robot, as long as it can connect the second vacuum suction cup 10 to the material transfer end of the handling robot. It is pre-configured that the handling robot can move the second vacuum suction cup 10 along a preset movement route. The material transfer principle of the handling robot is a prior art and will not be elaborated here.

[0069] It should be noted that in this embodiment, the first driving member 52 can adopt a linear driving device such as an electric push rod or a cylinder. The first rack 51 is connected to the push-pull end of the first driving member 52. As the first driving member 52 pushes the first rack 51 upward, the first gear 50 can rotate and drive the entire adsorption platform 2 to flip downward.

[0070] In addition, it can be understood that in other embodiments, the adsorption platform 2 can also be flipped by directly driving the adsorption platform 2 by a motor, or by using a pulley and motor structure to drive the first gear 50 to rotate, etc., which will not be elaborated here.

[0071] In some embodiments, referring to Figures 1 to 6The base frame 4 has a film collection area 40, and the adsorption platform 2 is arranged above the film collection area 40 in the height direction of the base frame 4. Corresponding to this embodiment, the base 41 is a through structure toward the adsorption platform 2, and the film collection area 40 corresponds to the through structure. A collection box or other structure can be arranged under the base 41 to collect the exported film. In the export state, the adsorption platform 2 is turned over to guide the torn film toward the film collection area 40.

[0072] In order to further improve the movement stability of the first rack 51, in some embodiments, referring to Figure 5 The first driving assembly 5 also includes a guide rail 53, a slide seat 54 and a moving part 55.

[0073] The guide rail 53 is fixed to the mounting plate 43, the first rack 51 is fixed to the side of the moving part 55 away from the mounting plate 43, and the moving part 55 is connected to the push-pull end of the first driving member 52.

The moving part 55 provides an adjustment area for the meshing of the first rack 51 and the first gear 50, and the position of the first rack 51 on the moving part 55 can be adjusted horizontally as needed. The first rack 51 is stably moved by the slide 54 and the guide rail 53, and the gear rack transmission structure is adopted, which has high transmission efficiency and rapid response, thereby improving the accuracy and sensitivity of the rotating adsorption platform 2.

[0074] In some embodiments, reference Figures 1 to 4 as well as Figure 6 The film pressing mechanism 3 includes a film pressing member 30 and a second driving component 31 .

[0075] The film pressing member 30 is rotatably connected to the mounting plate 43 via the second rotating shaft 32. The second driving assembly 31 connects the base frame 4 and the film pressing member 30, and the second driving assembly 31 is configured to drive the film pressing member 30 to rotate so that the film pressing member 30 clamps the surface film to be torn relative to the adsorption platform 2.

[0076] Specifically, in some embodiments, the second driving assembly 31 includes a second gear 310, a second rack 311, and a second driving member 312. The second gear 310 is coaxially fixedly connected to the rotation center of the film pressing member 30. In this embodiment, the second gear 310 is coaxially fixedly connected to the second rotating shaft 32. The second rack 311 meshes with the second gear 310, and the second driving member 312 is disposed on the mounting plate 43, and the second driving member 312 is connected to the second rack 311.

[0077] It should be noted that in this embodiment, the second driving member 312 can adopt linear driving devices such as electric push rods and cylinders. The second rack 311 is connected to the pushing and pulling end of the second driving member 312. As the second driving member 312 pushes the second rack 311 upward, the second gear 310 can rotate and drive the overall film pressing member 30 to clamp the film to be torn relative to the adsorption platform 2.

[0078] In addition, in order to improve the fixing effect of the film pressing member 30 on the surface to be torn, in some embodiments, referring to Figure 4 and Figure 6 , the film pressing member 30 can be provided with a film pressing pad 300 for pressing the film to be torn. The film pressing pad 300 can be made of materials such as rubber to improve the effect of friction and fixing the film to be torn.

[0079] It can be understood that the above film tearing process by Figures 1 to 4 is as follows:

[0080] The handling robot drives the second vacuum chuck 10 to adsorb the adhesive film 6 and move the adhesive film 6 above the adsorption platform 2. At this time, the film pressing member 30 is in a vertical state, and the second adsorption surface 100 is adjusted to align with the first adsorption surface 210;

[0081] The handling robot lowers the second vacuum chuck 10 so that the adhesive film 6 is carried by the first adsorption surface 210, and the first vacuum chuck 21 adsorbs the film to be torn. At this time, the second vacuum chuck 10 remains in the adsorption state;

[0082] The film pressing member 30 is driven to rotate so that the film pressing member 30 clamps the film to be torn relative to the first adsorption surface 210;

[0083] The handling robot is driven to move the second vacuum chuck 10 upward, so that the film to be torn remains on the first adsorption surface 210 under the action of the film pressing member 30 and the first vacuum chuck 21, and the film tearing is completed;
