Description

Technical Field

[0001] This utility model belongs to the field of battery electrode processing technology, specifically relating to a positioning device for rolling battery electrodes. Background Technology

[0002] Battery electrode rolling is a key process in lithium-ion battery manufacturing. Rolling allows the electrode materials to be arranged more tightly, increasing the content of active material per unit volume and thus improving the energy density of the battery. For example, for the positive electrode, rolling makes the coating composed of positive electrode active material, conductive agent and binder more compact, which helps to improve the charge and discharge performance of the battery.

[0003] During the rolling process of battery electrode sheets, a positioning device is required to position both sides of the battery electrode sheet. However, the current positioning device is difficult to adjust the positioning specifications when positioning the battery electrode sheet. When positioning battery electrode sheets of different widths, different positioning fixtures need to be changed. Therefore, the positioning flexibility before rolling the battery electrode sheet is poor. Utility Model Content

[0004] To address the aforementioned problems, this application provides a positioning device for rolling battery electrode sheets, comprising: Two vertical plate components are spaced apart in the first direction; The support platform is located between the two upright plate components and is connected to the two upright plate components; The protective cover is fixed to the top surface of the support platform. The drive assembly includes a power structure mounted on the bottom surface of the support platform and a transmission structure housed within the protective cover. Two positioning plates are spaced apart in a first direction and configured to move toward or away from each other in the first direction under the action of a drive assembly; A support roller is provided at a distance from the support platform in a second direction. The support roller extends along a first direction and is rotatably mounted on the upright plate member.

[0005] The protective cover, positioned above the dedicated support platform, serves two purposes: firstly, it supports the battery electrodes; secondly, it creates a closed protective space, effectively isolating external dust, impurities, and accidental collisions, providing comprehensive protection for the internal drive components, extending their lifespan, and ensuring their operational stability. Simultaneously, the protective cover houses a drive component for adjusting the distance between the two positioning plates. When positioning battery electrodes of different widths, operators no longer need to cumbersomely change positioning fixtures to fit different widths. They can simply adjust the distance between the two positioning plates using the drive component to quickly achieve a tight fit and reliable positioning of the battery electrodes, ensuring no lateral displacement during rolling. This simplifies the positioning process for battery electrodes of different specifications, significantly improving the flexibility and adaptability of pre-rolling positioning operations and effectively increasing overall production efficiency.

[0006] Furthermore, the power structure includes a motor and a drive shaft mounted on the output end of the motor, and the drive shaft extends vertically.

[0007] Furthermore, the transmission structure includes a first bevel gear and two transmission units arranged in a mirror-symmetric manner in a first direction. The first bevel gear is connected to the end of the drive shaft away from the motor. The transmission unit includes: A threaded rod body, extending along a first direction; A transmission seat is mounted on the threaded rod and configured to move linearly in a first direction as the threaded rod rotates, and the transmission seat is connected to the positioning plate. The second bevel gear is fixed to one end of the threaded rod and meshes with the first bevel gear.

[0008] By employing mirror symmetry involving the transmission unit, the movement of the two positioning plates can be synchronously controlled under the action of a single motor, so that the two positioning plates move closer or further apart in sync, thereby improving both the adjustment accuracy and the adjustment rate.

[0009] Furthermore, the top wall of the protective cover is provided with an adjustment hole for the transmission seat to slide, and the top end of the transmission seat protrudes from the adjustment hole and is connected to the positioning plate.

[0010] Furthermore, the transmission unit also includes a limiting block fixed to the bottom end of the transmission base and a limiting seat fixed to the bottom end of the limiting block, and the limiting seat is configured to slide along the top surface of the support platform.

[0011] Furthermore, the threaded rod is assembled to the top surface of the support platform via a bearing structure.

[0012] Furthermore, the motor is mounted on the bottom surface of the support platform via a fixed base.

[0013] Furthermore, the positioning device also includes a base plate component fixed to the bottom end of the upright plate component.

[0014] Furthermore, the positioning device also includes a support block disposed vertically between the support platform and the base plate component, and the support block is connected to the support platform and the base plate component.

[0015] Furthermore, the positioning device also includes a controller mounted on the upright plate component, and the controller is electrically connected to the motor. Attached Figure Description
