Description

Technical Field

[0001] The present invention relates to the field of blade battery manufacturing, and in particular to a water-cooled capacity-dividing integrated machine. Background Art

[0002] In the battery production process, capacity classification refers to subjecting the activated blade batteries to several full-load charge and discharge cycles to test the internal resistance and charge and discharge capacity. This is used to eliminate batteries with quality problems (such as too low capacity, too much self-discharge, too much internal resistance), and to group the batteries by capacity and internal group in order to select batteries with similar performance to form a battery pack.

[0003] The invention patent with publication number CN117766885A proposes a motion mechanism for blade lithium-ion battery testing, which charges and discharges the blade battery by pressing the blade battery up and down through the bracket connected to the cylinder. The operation of the device and the charging and discharging of the battery generate a lot of heat; at the same time, because the positive pin plate assembly and the negative pin plate assembly dock the blade battery from the top and bottom respectively, the device occupies a larger space than the square battery capacity division device. The overheating problem and the large size problem have an adverse effect on the efficiency of the capacity division process. Summary of the invention

[0004] In view of the above problems, the present invention proposes a water-cooled capacity-dividing integrated machine, whose design concept is to improve the circulation efficiency of the refrigeration system by installing an air duct for internal circulation on the inner wall of the capacity-dividing box, optimize the position and number of fans, and thereby improve the temperature stability of the capacity-dividing equipment.

[0006] A top air duct 34 is provided on the top of the sub-capacity box, and vertical side air ducts 24 are provided on the left and right sides of the sub-capacity box; the top air duct 34 is connected to the side air duct 24;

[0007] The lower surface of the top air duct 34 is connected to several top fan assemblies 3 arranged side by side on the left and right, and the top fan assembly 3 can blow air from the sub-capacity box into the top air duct 34; the side air duct 24 is provided with a middle fan assembly 2, a water-cooled plate assembly 4 and a lower fan assembly 1 from top to bottom; the middle fan assembly 2 can blow air from top to bottom, the water-cooled plate assembly 4 is connected to an external water cooling mechanism, and the lower fan assembly 1 can blow air from the side air duct 24 into the sub-capacity box, so that the cooled air flows through the negative electrode needle plate assembly 7, the battery tray 57 and the positive electrode genuine assembly 6 and is then blown into the top air duct 34 by the top fan assembly 3 again.

[0008] More specifically, the top fan assembly 3 includes a top fan plate 32 , on which a plurality of top fans 31 are arranged; a top fan handle 33 is arranged at the front end of the top fan plate 32 , which can be pulled forward to extract the top fan assembly 3 .

[0009] More specifically, the middle fan assembly 2 includes a middle fan plate 22 , on which a plurality of middle fans 21 are arranged; a middle fan handle 23 is arranged at the front end of the middle fan plate 22 , which can be pulled forward to extract the middle fan assembly 2 .

[0010] More specifically, the bottom fan assembly 1 includes a bottom fan plate 12 , on which a plurality of bottom fans 11 are arranged; a bottom fan handle 13 is arranged at the front end of the bottom fan plate 12 , and the bottom fan assembly 1 can be pulled forward to be drawn out.

[0011] More specifically, an air guide plate 9 is provided at the internal connection between the top air duct 34 and the side air duct 24 to adjust the wind direction.

[0018] During operation, the top fan assembly 3, the middle fan assembly 2 and the bottom fan assembly 1 are turned on. The hot air generated by the operation of the equipment is blown into the top air duct 34 by the top fan assembly 3, and then cooled by the water cooling plate assembly 4 after passing through the air guide plate 9 and the middle fan assembly 2. The cooled air is then blown into the middle of the sub-capacity box by the bottom fan assembly 1, flows through the negative electrode needle plate assembly 7, the battery tray 57 and the positive electrode needle plate assembly 6 in sequence, and finally blown into the top air duct 34 again by the top fan assembly 3.

[0019] The technical effect of the present invention is that the lower fan assembly, the middle fan assembly, the top fan assembly and the water-cooled plate assembly are integrated into an integrated machine inside the sub-capacity box, which effectively saves the storage space and ensures the uniformity of the ambient temperature and the battery surface temperature in the sub-capacity storage space through efficient cold air internal circulation; the fan assembly can be pulled out by a handle, which is convenient for maintenance and inspection by external staff.
