[0002] At present, after the battery cell is filled with liquid, it is activated by standing still at room temperature. This process takes 24 to 36 hours. The process time consumed by the electrolyte to completely penetrate the electrode is relatively long, which affects the production cycle and storage site costs. Therefore, it is necessary to shorten the time for the electrolyte to completely penetrate the electrode, thereby improving production efficiency and reducing the production cycle.

[0003] Therefore, a device is needed that can effectively shorten the time required for the electrolyte to completely infiltrate the electrode. Utility Model Content

[0007] By adopting the above technical solution, the rotating motor can drive the battery cell placement rack to rotate along the horizontal rotation axis, and the battery cell placement rack can drive the battery cell to be processed to flip, so that the electrolyte inside the battery cell to be processed flows, accelerates the reaction rate, and effectively shortens the time required for the electrolyte to completely infiltrate the electrode.

[0008] As an improved solution, the rotating motor is connected to the battery cell placement rack via a transmission belt / transmission chain, and each rotating motor is connected to a plurality of battery cell placement racks.

[0009] By adopting the above technical solution, one rotating motor can drive multiple battery cell mounting racks to rotate, reducing the number of rotating motors required for the overall equipment and the floor space occupied, thereby reducing equipment costs.

[0011] By adopting the above technical solution, several battery cell placement racks can be close to each other and arranged in a form similar to shutters, and can rotate synchronously without interfering with each other, so that more battery cells to be processed can be placed and accelerated in the same space, saving site costs and improving production efficiency.

[0012] As an improved solution, the battery cell placement rack is in the shape of a drum as a whole; the battery cell placement rack is provided with a plurality of loading positions matching the battery cells to be processed.

[0013] By adopting the above technical solution, more cells to be processed can be arranged in one cell placement rack, and it can be ensured that each cell to be processed can be fully turned over within one rotation cycle of the cell placement rack, thus ensuring the uniformity of the processing flow and quality stability of the cells to be processed.

[0014] As an improved solution, the plurality of loading positions are evenly distributed on a plurality of concentric circles coaxial with the gripping axis of the battery cell placement rack.

[0015] By adopting the above technical solution, more battery cells to be processed can be processed on a battery cell placement rack that occupies the same volume.

[0016] As an improved solution, the battery cell placement rack is provided with a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are hinged at one end, and a locking switch is provided at the other end, and a loading position matching the battery cell to be processed is provided between the first clamping plate and the second clamping plate.

[0017] By adopting the above technical solution, the battery cell placement rack can clamp and fix the battery cell to be processed in the middle by using the first clamping piece and the second clamping piece to prevent the battery cell to be processed from falling.

[0018] As an improved solution, an infrared heating device is provided on the battery cell placement rack, and the infrared heating device is arranged facing the battery cell tab position.

[0019] By adopting the above technical solution, the tab portion of the battery cell to be processed can be heated in a targeted manner by the infrared heating device, thereby further increasing the reaction rate and shortening the time required for complete infiltration.

[0020] As an improved solution, a hot air blower is arranged on the bracket body, and the hot air blower is arranged facing the battery cell placement rack.

[0021] By adopting the above technical solution, the electrolyte in the battery cell to be processed can be heated by the hot air blown out by the hot air blower, further improving the reaction rate and shortening the time required for complete infiltration.
