Example (b):

as shown in fig. 1-4, the present invention provides a novel battery aging device, which comprises a base 7, a clamping member 8, a driving device 1 and a plurality of rotating disks 2. The driving device 1 comprises a driving motor 11 and a connecting column 9; the spliced pole 9 is rotatable to be set up in the upper surface of base 7, and driving motor 11 sets up in base 7 lower surface and transmission connection in spliced pole 9. The driving motor 11 rotates to drive the connecting column 9 to rotate. The lower end of the rotating disc 2 is provided with a coupling groove 22 receiving the coupling post 9. In particular, the size of the coupling groove 22 is slightly larger than the size of the coupling post 9, so that the coupling post 9 can just be inserted into the coupling groove 22. The upper end of the rotating disc 2 is also provided with a connecting column 9. This enables the connecting slot 22 of the rotary disc 2 to be plugged into the connecting column 9 of the rotary disc 2 below, so that several rotary discs 2 can be stacked up. In order to ensure that the plurality of rotary discs 2 can rotate, the connecting column 9 is a square column and the connecting groove 22 is arranged in a square shape. The upper surface of the rotating disc 2 is provided with a plurality of placing grooves 3 for placing materials. The clamping piece 8 is arranged on the base 7 in a lifting way. The clamping member 8 is provided with a rotatable rotary seat 81 directly above the connecting column 9. The rotary base 81 is provided with a coupling groove 22. In particular, the clamping member 8 is L-shaped. A slide bar is arranged at a vertical section of the clamping device, and the base 7 is matched with the slide bar to be provided with a sliding groove, so that the clamping piece 8 can slide up and down relative to the base 7. The clamp 8 is driven to move up and down by a cylinder or the like. The horizontal part of the clamping member 8 is provided with a rotating seat 81. The rotary seat 81 and the horizontal portion of the clamping member 8 can be connected by means of a rotary bearing 4. So that the rotation of the rotating seat 81 with respect to the clamping member 8 is smoother.

When the novel battery aging device is used, a battery to be aged is placed in the placing groove 3. The coupling slot 22 of the rotary plate 2 is then snapped outside the coupling post 9 of the drive unit 1, so that the rotary plate 2 and the drive unit 1 are coupled. And then, continuously superposing the rotating discs 2 according to the needs, so that the aging amount reaches the requirement. In this process, the coupling groove 22 of the upper rotating disk 2 receives the coupling post 9 of the lower rotating disk 2. Finally, the clamping member 8 is moved downward. So that the coupling groove 22 of the rotary base 81 is fastened to the outside of the topmost coupling post 9. At this time, the clamping piece 8 clamps the plurality of overlapped rotating disks 2, so that the rotating disks 2 are prevented from falling off in the rotating process. The driving device 1 can drive the plurality of rotating discs 2 to rotate by rotating. Thereby subjecting the electrolyte in the plurality of electric cores to an outward centrifugal force. The electrolyte is squeezed by the centrifugal force to pass through the diaphragm more quickly or to be better soaked. The aging efficiency is improved.

The novel battery aging device pushes the electrolyte to rapidly pass through the diaphragm or rapidly infiltrate into the battery through the centrifugal force generated by the rotation of the battery. Meanwhile, the overlapping number of the rotating disks 2 can be set according to the requirement, so that the aging amount of the battery is matched with the equipment direction, and the use is flexible.

In the present embodiment, the placement slot 3 is rotatably provided to the rotating disk 2 so that the placement slot 3 is provided in a variable direction. After the battery cell is aged for a sufficient time in one direction, the angle of the battery cell is changed by rotating the placing groove 3, so that the electrolyte is subjected to a centrifugal force in the direction opposite to the previous direction, and the electrolyte is soaked on the other side of the battery cell. Electrolyte can be extruded to any direction through rotating the placing groove 3, and then the inside quilt that all can be fine everywhere of electric core is aged.

In the present embodiment, the placement groove 3 is provided in the circular groove 21. The circular groove 21 confines the placing groove 3 inside thereof to avoid the placing groove 3 from sliding along the surface of the rotating disk 2 when the rotating disk 2 rotates.

In this embodiment, the bottom of the placing groove 3 is connected with a poking wheel 5 through a rotating shaft 4. The rotation shaft 4 penetrates the bottom of the rotation plate 2 and extends to the lower side of the rotation plate 2. The outer diameter of the rotating shaft 4 is slightly smaller than the inner diameter of the through hole, so that the rotating shaft 4 can rotate in the through hole. The poking wheel 5 is arranged at the lower end of the rotating shaft 4. The placing groove 3 can be well limited in the circular groove 21 through the rotating shaft 4 and the poking wheel 5, and the placing groove 3 is better prevented from being separated from the rotating disk 2. In addition, the placing direction of the placing groove 3 can be conveniently adjusted through the poking wheel 5.

In this embodiment, the plurality of circular grooves 21 are circularly distributed around the rotation center of the rotating disk 2. The dial 5 is an external gear. The lower end of the rotating disk 2 is rotatably provided with a stirring ring 6. The inner wall of the poking ring 6 is provided with inner teeth meshed with the poking wheels 5. The rotating stirring ring 6 can make the stirring wheels 5 rotate simultaneously, so that the placing grooves 3 connected to the stirring ring 6 can be conveniently adjusted. Avoid the trouble that adjustment standing groove 3 brought one by one, raise the efficiency. Specifically, an annular dovetail groove is formed in the lower end of the rotating disc 2. The toggle ring 6 is provided with a slide 61 received in the dovetail groove. This allows the toggle ring 6 to be well constrained to the lower end of the rotary plate 2 and the toggle ring 6 to be well rotatable relative to the rotary plate 2.

In this embodiment, the rotating disk 2 is distributed with a plurality of groups of placing grooves 3 along the radial direction thereof. The plurality of placing grooves 3 of each group are distributed annularly. A plurality of placing grooves 3 of each group are correspondingly provided with a poking ring 6. The distance between each group of placing grooves 3 and the rotation center of the rotating disk 2 is different, which causes the magnitude of the centrifugal force applied to the battery cells in each group of placing grooves 3 to be different. The closer the distance to the center of rotation, the smaller the centrifugal force. The aging efficiency of the battery cells is different when the battery cells are placed in the placing grooves 3 of different groups. During the specific use, can place the electricity core in different groups standing groove 3 as required.

In this embodiment, the plurality of dial rings 6 are distributed in a step shape. The outermost toggle ring 6 is at the shortest distance from the top surface of the rotary disc 2. This enables the innermost toggle ring 6 to be easily operated and used.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
