[0042] See also Figure 1 and Figure 2 , a material separation assembly provided in an embodiment of the present application includes: a material belt conveying mechanism 10 and a material taking mechanism (not shown in the figure);

[0043] The material conveyor mechanism 10 is mounted on the main body of the device. It includes a feed reel 11, a take-up reel 12, and a friction wheel 13. The feed reel 11 unwinds the material 30. The take-up reel 12 winds up the unloaded material 30. The take-up mechanism removes the material from the material 30 at the unloading station.

[0044] Specifically, the material strip 30 is unwound from the unwinding reel 11 and moves toward the take-up reel 12. The unwound material strip 30 is wound around the unwinding reel 11 and extends from the unwinding reel 11, then passes through multiple support rollers. After the material is removed by the take-up mechanism, the unwound material strip 30 is wound onto the take-up reel 12.

[0045] The friction wheel 13 abuts against the material strip 30 after unloading, and is used to drive the material strip 30 to move.

[0046] As an embodiment, the take-up reel 12 serves as a power output structure of the material belt 30 , that is, the rotation of the take-up reel 12 can drive the material belt 30 to move and be wound on the take-up reel 12 .

[0047] In this embodiment, the friction wheel 13 can promote the conveyance of the material belt 30. On the one hand, it can serve as an auxiliary driving force for the conveyance of the material belt 30 to reduce the occurrence of slippage of the material belt 30. On the other hand, it can improve the accuracy of the conveyance of the material belt 30, making it easier for the material picking mechanism to perform automatic fixed-point unloading at the unloading station.

[0048] Specifically, the rotation of the friction wheel 13 can be controlled by a servo motor. Specifically, the servo motor is mounted on the main body of the device, and its output is connected to the friction wheel 13. This servo motor enables precise quantitative control of the friction wheel 13, ensuring precise matching of the rotational feed rate of the friction wheel 13 with the material retrieving rate of the retrieving mechanism.

[0049] It should be noted that, in this embodiment, the material may be an insulating member such as an insulating cap for assembly with a battery cell. The material strip 30 serves as a carrier for the material, and a plurality of materials may be arranged on the material strip 30.

[0050] In one embodiment, see Figure 3 The friction wheel 13 can be connected to a ratchet 132. The ratchet 132 is used to connect a driving mechanism such as a motor to ensure that the friction wheel 13 can only rotate in the direction of conveying the material belt 30.

[0051] As an implementation manner, the friction wheel 13 may be a ratchet wheel; and the positioning member 131 may be a pawl on the friction wheel 13 .

[0052] In one embodiment, a visual detector 14 is further included; positioning marks corresponding to the materials are set on the material belt 30; the visual detector 14 faces the unloading station and is used to detect whether the positioning mark reaches the preset position.

[0053] The positioning mark can be, for example, a positioning hole provided on the material strip 30, which facilitates identification by the visual detector 14. The visual detector 14 can be, for example, a lens. The visual detector 14 detects the material's position. When the positioning mark reaches a predetermined position, the material removal mechanism removes the material from the material strip 30. The visual detector 14, in conjunction with the quantitative conveying of the friction wheel 13, ensures accurate material delivery and reduces the impact of cumulative errors during the material conveying process.

[0054] As a further improvement, the friction wheel 13 is provided with a plurality of positioning members 131 ; during the rotation of the friction wheel 13 , the plurality of positioning members 131 and the plurality of positioning marks are matched one by one, so that the visual detector 14 can detect the conveying distance of the material belt 30 .

[0055] In this embodiment, the plurality of positioning members 131 may be evenly distributed at equal intervals around the circumference, or may be arranged at unequal intervals according to actual needs.

[0056] As an embodiment, a scale 133 is provided on the friction wheel 13 to facilitate debugging of the friction wheel 13 during installation.

[0057] In another embodiment provided in the present application, the material separation component also includes a storage box 22; the material belt 30 after unloading includes a vertical section with a downward conveying direction; the storage box 22 is arranged on the vertical section, or the storage box 22 is arranged below the vertical section.

[0058] When the material taking mechanism fails to take the material, the material will remain on the material belt 30. By providing the vertical section and the material storage box 22, the remaining material will fall into the material storage box 22 when passing through the vertical section, thereby not affecting the winding of the material belt 30.

[0059] In one embodiment, the material belt conveying mechanism 10 further includes: a pressure wheel 15; the pressure wheel 15 can be rotatably arranged, and the pressure wheel 15 can be movably arranged next to the friction wheel 13; the material belt 30 passes between the pressure wheel 15 and the friction wheel 13; the pressure wheel 15 is used to squeeze the material belt 30 so that the material belt 30 abuts against the friction wheel 13.

[0060] Specifically, the pressure wheel 15 can be disposed on the aforementioned device body and be movable on the device body. When threading the material strip 30, the pressure wheel 15 is first moved to increase the distance between the pressure wheel 15 and the friction wheel 13. After the material strip 30 has passed through, the pressure wheel 15 is further moved to decrease the distance between the pressure wheel 15 and the friction wheel 13. This allows the pressure wheel 15 to squeeze the material strip 30 and push it against the friction wheel 13, ensuring that the friction wheel 13 can drive the material strip 30 to move.

[0061] In one embodiment, an electrostatic eliminator 23 is further included; the electrostatic eliminator 23 is arranged next to the unloading station and is used to eliminate static electricity on the material belt 30.

[0062] The static eliminator 23 is mounted on the main body of the device. Furthermore, a plasma nozzle 24 can be mounted on the main body of the device. The plasma nozzle 24 is positioned in front of the unloading station, facing the material belt 30, to remove static electricity from the material belt 30, thereby preventing the material on the material belt 30 from being lifted or deviated by static electricity.

[0063] In other embodiments provided in the present application, the material tape conveying mechanism 10 further includes: a film reel 16 ; the film reel 16 is used to reel up the protective film 31 on the material tape 30 to expose the material on the material tape 30 .

[0064] In this embodiment, a protective film 31 is laid over the material strip 30, which protects the insulating member 52. The protective film 31 can be wound up by the film reel 16. For example, while the material strip 30 is being conveyed, a worker can manually tear off the protective film 31 at the top of the material strip 30 and secure the protective film 31 to the film reel 16 by gluing or other means. The film reel 16 then rotates, rewinding the protective film 31 and exposing the material on the material strip 30.

[0065] A conveying channel for conveying the material strip 30 is formed between the unwinding reel 11 and the receiving reel 12. The protective film 31 of the material strip 30 is separated on the conveying channel.

[0066] As an embodiment, the material separation assembly provided in the embodiments of the present application can be installed in a pole piece battery production system, which includes the above-mentioned device body; the device body includes: a first device and a second device; the first device can be used to separate the material strips and unload the material; correspondingly, the above-mentioned material strip conveying mechanism 10 and material removal mechanism can be installed on the first device. The second device can be used to carry out the next process of the material. For example, if the material is an insulating cap, the assembly mechanism for assembling the insulating cap can be installed on the second device.

[0067] In one embodiment, the material belt conveying mechanism 10 further includes a film guide 21 ; the film guide 21 can be fixed to the first device by an adjusting screw; when the adjusting screw is loosened, the film guide 21 can move on the first device to adjust the tightness of the protective film 31 .

[0068] In practical applications, the film guide 21 can be, for example, two rollers close to each other, with the protective film passing through the gap between the two rollers. In this embodiment, in order to facilitate connecting the separated protective film 31 to the film winding reel 16, the film guide 21 is single.

[0069] In another embodiment provided by the present application, after the material is taken off from the material belt 30 , the material taking structure can also transfer the material to the assembly mechanism of the second device.

[0070] Optionally, the material retrieving structure includes: a robotic arm and a suction nozzle; the suction nozzle is arranged on the robotic arm. The robotic arm is a multi-axis robotic arm that can drive the suction nozzle to move in multiple directions to achieve material retrieval and drive material unloading and transfer.

[0071] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
