A coating fixture for processing low-temperature fast-charging lithium-ion batteries

Abstract

This utility model relates to the field of lithium-ion battery technology and discloses a coating fixture for processing low-temperature fast-charging lithium-ion batteries. It includes a bottom support base, a coating platform fixedly connected to the top of the bottom support base, and a coating fixture body on the top of the coating platform. A top support plate, capable of reciprocating horizontally along the top of the coating platform, drives a rotating cleaning brush to reciprocate horizontally along the top of the coating platform, improving the cleaning effect on the coating platform surface. Simultaneously, a continuously rotating drive fan generates downward airflow along the inner side of the bottom connecting cylinder. This downward airflow blows along the bottom guide plate onto the surface of the coating platform, blowing away cleaning debris generated by the rotating cleaning brush and reducing the accumulation of particulate matter on the coating platform surface. This improves the efficiency of lithium-ion battery coating operations using the coating fixture body and enhances the coating effect for low-temperature fast-charging lithium-ion batteries.

[0015] Please see Figures 1 to 4This utility model provides a technical solution: a coating fixture for processing low-temperature fast-charging lithium-ion batteries, including a bottom support 1, a coating platform 2 fixedly connected to the top of the bottom support 1, a coating fixture body 3 set on the top of the coating platform 2, a side support frame 401 fixedly connected to one side of the bottom support 1, a side motor 402 fixedly connected to the top of the side support frame 401, a threaded column 403 fixedly connected to the output shaft of the side motor 402, a threaded ring 406 threadedly connected to the surface of the threaded column 403, a fixed side plate 407 fixedly connected to one side of the threaded ring 406, a top support plate 408 fixedly connected to one side of the fixed side plate 407, a left support frame 601 fixedly connected to one side of the top support plate 408, a drive motor 603 fixedly connected to one side of the left support frame 601, a side fixing rod 604 fixedly connected to the output shaft of the drive motor 603, and a cleaning brush 605 fixedly connected to the surface of the side fixing rod 604.

[0016] It should be noted that during use, the coating fixture 3 is first moved horizontally along the surface of the coating platform 2 to perform the coating operation. The rotating side fixing rod 604 will drive the cleaning brush 605 to rotate and clean along the surface of the coating platform 2, sweeping away dust particles and other adhering objects on the surface of the coating platform 2. In addition, the top support plate 408, which can move horizontally back and forth along the top of the coating platform 2, improves the cleaning effect on the surface of the coating platform 2. The surface of the top support plate 408 is provided with a top connecting ring 409. The top of the top connecting ring 409 is fixedly connected to a bottom connecting cylinder 505. The top of the bottom connecting cylinder 505 is fixedly connected to a side fixing frame 501. The inner side of the side fixing frame 501 is fixedly connected to a top motor 502.

[0017] In an optional embodiment, a barrier net 506 is fixedly connected to the inner side of the bottom connecting cylinder 505.

[0018] It should be noted that by using the barrier mesh 506 for filtration, when the drive fan 504 rotates to draw in external air, the barrier mesh 506 filters out particulate matter, thereby improving the airflow cleaning effect.

[0019] In an optional embodiment: one end of the threaded post 403 is fixedly connected to a bearing disk 404, and a side support plate 405 is fixedly connected to one side of the bearing disk 404.

[0020] It should be noted that, through the movable support of the No. 1 bearing disk 404, the threaded column 403 is stably supported on one side of the side support plate 405 when it rotates, thereby improving the stability of the rotation of the threaded column 403.

[0024] It should be noted that the continuous downward airflow will blow along the bottom guide plate 4013 onto the surface of the painting platform 2, blowing the cleaning debris generated by the rotation of the cleaning brush 605 away from the surface of the painting platform 2. The bottom guide plate 4013 is in an inclined state, which will improve the stability of the airflow direction and improve the cleaning effect of the airflow.

[0025] In an optional embodiment: a second bearing disc 606 is fixedly connected to one side of the side fixing rod 604, a right support frame 602 is fixedly connected to one side of the second bearing disc 606, and one side of the right support frame 602 is fixedly connected to one side of the top support plate 408.

[0026] It should be noted that the rotating side fixing rod 604 is movably supported on one side of the right support frame 602 by the second bearing disc 606, and the support of the second bearing disc 606 improves the rotational stability of the side fixing rod 604.

[0027] The specific usage and function of this embodiment are as follows: Before coating, the side motor 402 is started first, and the side motor 402 drives the threaded column 403 to rotate. The rotating threaded column 403 will be connected to the threaded ring 406 by the thread. When the threaded column 403 rotates, it drives the fixed side plate 407 to move horizontally. The fixed side plate 407, which moves horizontally, will drive the top support plate 408 to move horizontally. The horizontally moving top support plate 408 will drive the side extension frame 4010 to move synchronously. After starting the drive motor 603, the drive motor 603 drives the side fixing rod 604 to rotate. The rotating side fixing rod 604 will drive the cleaning brush 605 to rotate and clean along the surface of the coating platform 2, sweeping away dust particles and other debris adhering to the surface of the coating platform 2. In addition, the top support plate 408, which can move horizontally back and forth along the top of the coating platform 2, will drive the rotating cleaning brush 605 to move horizontally back and forth along the top of the coating platform 2, thus improving the cleaning effect on the surface of the coating platform 2. Start the top motor 502, which drives the bottom transmission rod 503 to rotate. The rotating bottom transmission rod 503 will drive the transmission fan 504 to rotate along the inner side of the bottom connecting cylinder 505. The continuously rotating transmission fan 504 will generate a downward air force along the inner side of the bottom connecting cylinder 505. The continuously downward air force will blow along the bottom guide plate 4013 onto the surface of the coating platform 2, blowing away the cleaning debris generated by the rotating cleaning brush 605 from the surface of the coating platform 2. At the same time, it reduces the accumulation of particulate matter on the surface of the coating platform 2, improves the effect of lithium-ion battery coating operation using the coating fixture 3, and improves the coating effect of low-temperature fast-charging lithium-ion batteries.
