The first driving device 11 may be provided with a driving shaft 10 and a cam divider. The drive shaft 10 is in transmission connection with the platform 13. For example, the first driving device 11 can drive the platform 13 to rotate through the driving shaft 10. In addition, the first driving device 11 can also drive the platform 13 to go up and down through the driving shaft 10. The cam divider is a high-precision slewing device that can accurately output rotation force, and the drive shaft 10 drives the platform 13 to rotate at a predetermined angle in the circumferential direction.
[0048] In this embodiment, the platform 13 can be used to place the lid closing device. Specifically, the platform 13 may be in the form of a disc. Of course, the specific form of the platform 13 is not limited to the above examples. The platform 13 is in transmission connection with the drive shaft 10, and the platform 13 can at least be driven by the drive device for rotational movement. In addition, the platform 13 can also be driven by the drive shaft 10 for lifting motion. Specifically, the platform 13 has a first surface and a second surface opposite to each other, wherein the first surface may be an upper surface, and the opposite second surface may be a lower surface.
[0049] In this embodiment, a plurality of lid closing devices are installed on the platform 13. The plurality of cover closing devices are centered on the drive shaft 10 and are distributed at intervals along the circumferential direction. The cover closing device may include: an upper closing cover 7 and a lower closing cover 6. Wherein, the bottom cover plate 6 may be fixed on the first surface. When the bottom closing cover 6 is fixed, the top closing cover 7 can be driven by the second driving device 12 to realize the separation and closing operation of the top closing cover 7 and the bottom closing cover 6. Of course, the embodiment in which the upper closing cover 7 is fixed is not excluded.
[0050] In this embodiment, the second driving device 12 is used to provide power for opening and closing the lid closing device. Specifically, the second driving device 12 may include a power source and a transmission mechanism connected to the power source. The transmission mechanism is connected with the upper closing cover 7 through the connecting member 8, and can be connected with the lower closing cover 6, and can also be connected with the upper closing cover 7 and the lower closing cover 6. In the following embodiments, the transmission mechanism is mainly connected to the upper closure cover 7 through the connecting member 8. In other cases, the implementation manners can be adjusted with reference to the manner in which the transmission mechanism is connected to the upper closure cover 7 and the examples are not repeated in this application.
[0051] Wherein, since the upper closing cover 7 and the lower closing cover 6 generally need to be switched between: closing or separating, the power source can be the cylinder 2 to simplify the structure of the system and reduce the overall cost.
[0052] In one embodiment, the transmission mechanism may include: a guide rail 3, a mounting seat 4 that can slide relative to the guide rail 3 under the push of the cylinder 2, a rack 5 mounted on the mounting seat 4, and a rack 5 through a bracket 90 is fixed to the gear 9 on the platform 13. When the cylinder 2 pushes the rack 5 close to the drive shaft 10, it drives the gear 9 to rotate in the first direction, and the upper cover plate 7 and the lower cover cover are driven by the connecting member 8 The plate 6 is separated; when the cylinder 2 pushes the rack 5 away from the drive shaft 10, it drives the gear 9 to rotate in a second direction opposite to the first direction, and the connecting member 8 drives the The upper closing cover 7 and the lower closing cover 6 are closed.
[0053] In this embodiment, the transmission mechanism may mainly include a gear 9 and a rack 5 transmission mechanism. The cylinder 2 moves relative to the gear 9 through the rack 5 to drive the gear 9 to rotate, thereby driving the cover plate connected to the gear 9 to rotate, and realize the separation and closing between the two cover plates. Wherein, the guide rail 3 can be arranged on the platform 13. The lower end of the mounting base 4 may be provided with a guide rail slider matching the guide rail 3.
[0054] In one embodiment, the lower cover plate 6 is fixed on the first surface, and the transmission mechanism is connected to the upper cover plate 7 through a connecting member 8.
[0055] In this embodiment, the bottom cover 6 can be fixed on the first surface (ie, the upper surface) of the platform 13. The transmission mechanism can be connected with the upper closure cover 7 through the connecting member 8.
[0056] The platform 13 is provided with an installation groove for installing the gear 9. An elongated hole 60 matched with the mounting groove is provided at one end of the bottom closing cover plate 6 on the platform 13. The gear 9 passes through the long hole 60 and the mounting groove to mesh with the rack 5. One end of the upper cover plate 7 located on the platform 13 is fixed to the gear 9. When the cylinder 2 pushes the rack 5 to move relative to the gear 9, the relative position of the upper cover plate 7 and the lower cover plate 6 can be changed to realize the separation or closure of the two.
[0057] When the aluminum-plastic film automatic lid closing system for soft-pack batteries provided in the embodiment of the application is used for battery production, the second driving device 12 can be started, and the power source can be used to connect the power source through the transmission mechanism and the connecting member 8.

When the cover closing device is at the first station, the second driving device 12 can realize the opening and closing of the upper cover 7 and the lower cover 6. When the upper cover plate 7 and the lower cover plate 6 of the cover closing device are in a separated state, the aluminum plastic film can be put into the cover closing device, and the soft pack battery can be put into the aluminum plastic film. Then, the second driving device 12 closes the upper cover 7 and the lower cover 6. Then, the platform 13 can be rotated by the first driving device 11 to switch the cover closing device that has been inserted into the shell to the second station of the platform 13. An aluminum-plastic film cutting device may be provided at the second station. When the cover closing device reaches the second station, the aluminum plastic film cutting device can be used to cut the four sides of the aluminum plastic film. Further, the platform 13 can be rotated again by the first driving device 11 to switch the cut lid closing device to the third station of the platform 13. The third station may be provided with an aluminum-plastic film packaging device. When the cover closing device reaches the third station, the aluminum plastic film packaging device can be used to package the cut aluminum plastic film on the four sides. Finally, the platform 13 can be rotated by the first driving device 11, the packaged lid closing device can be switched to the fourth station of the platform 13, and the battery in the lid closing device can be taken out.
[0062] Further, in order to prevent equipment interference in different working positions, the platform 13 can also be driven up and down by the driving device.
[0063] In one embodiment, the number of the lid closing device may be multiple, for example, four, respectively: the first lid closing device 61, the second lid closing device 62, the third lid closing device 63, and the The four-closing device 64 is arranged at even intervals along the circumferential direction.
[0064] When there are multiple cover closing devices, the soft-pack battery aluminum-plastic film automatic cover closing system can be used to manufacture multiple batteries at the same time, which can further improve battery production efficiency.
[0065] The aluminum-plastic film automatic lid closing system for soft-pack batteries provided in the embodiment of the present application can use the first driving device 11 to rotate the platform 13 according to the needs of the workstation. When the lid closing device reaches the designated position, the second driving device is used 12.
