The heat dissipation assembly includes a plurality of air supply devices and a mounting bracket, and the plurality of air supply devices are installed on the mounting bracket; The battery tray is hollowed out at positions corresponding to the battery ears, and the mounting bracket can be movably mounted on the needle bed body, so that the mounting bracket drives the multiple air supply devices to movably attach to the multiple first heat dissipation holes of the battery tray, so that wind blows toward the battery ears.

A support seat is arranged on the moving frame, and the mounting bracket is rotatably installed on the support seat; A rib is arranged on the mounting bracket. When the driving cylinder drives the moving frame to rise, the rib can be pressed by the battery tray to drive the mounting bracket to rotate, so that the mounting bracket is switched from the unfolded position to the contracted position.

[0008] Further, a first convex column is arranged on the support seat, a second convex column is arranged on the mounting bracket, and a tension spring is connected between the first convex column and the second convex column.

Detailed Embodiments

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 9 , the present invention also provides a battery formation and grading pin bed.

[0022] The battery formation and grading pin bed includes a pin bed main body 100, a battery tray 200, and a heat dissipation assembly 300; the battery tray 200 is arranged on the pin bed main body 100, and the battery tray 200 is used for carrying a plurality of batteries 210; the heat dissipation assembly 300 is arranged on the pin bed main body 100, and heat dissipation assemblies 300 are installed on both sides of the battery tray 200. The heat dissipation assembly 300 includes a plurality of air supply devices 310 and a mounting bracket 320, and the plurality of air supply devices 310 are installed on the mounting bracket 320; a plurality of first heat dissipation holes 311 are formed in a hollowed-out manner at positions corresponding to the tab ears of the batteries on the battery tray 200. The mounting bracket 320 is movably installed on the pin bed main body 100, so that the mounting bracket 320 drives the plurality of air supply devices 310 to move and adhere to the plurality of first heat dissipation holes 311 of the battery tray 200, so that the wind blows to the tab ears 120 of the batteries 210.

[0023] Specifically, a probe module 110 is further installed on the pin bed main body 100, and the probes in the probe module 110 are used to contact the tab ears 120 of the batteries 210 for charging and discharging. The air supply device 310 can be a fan or a blower for air supply, which has a heat dissipation effect on the battery. It can be understood that the tab ear 120 is the part where the heat is most concentrated during the formation or grading of the battery 210. By arranging a dense plurality of first heat dissipation holes 311 at positions corresponding to the tab ears of the battery on the battery tray 200 and arranging the plurality of first heat dissipation holes 311 in a "wind comb" shape, it is more conducive to guiding the wind and improving the temperature balance effect of each battery 210, and guiding the wind to directly blow to the tab ear 120 where the battery 210 generates the most concentrated heat, thereby improving the heat dissipation efficiency of the battery 210. At the same time, the mounting bracket 320 can be moved so that the plurality of air supply devices 310 directly adhere to the first heat dissipation holes 311 of the battery tray 200 to actively assist in blowing and dissipating heat, shortening the blowing distance, reducing the obstruction of air flow, and ensuring that the air supply device 310 can blow air directly against the first heat dissipation holes 311, further improving the heat dissipation efficiency of the battery 210.

[0024] Please refer to Figures 1 to 3, further, the mounting bracket 320 is rotatably mounted on the bed body 100, so that the mounting bracket 320 can switch back and forth between the deployed position and the retracted position; in the deployed position, the heat dissipation components 300 on both sides are respectively opened toward the outside away from the battery tray 200; in the retracted position, the plurality of air supply devices 310 are pressed against the heat dissipation holes of the battery tray 200. Specifically, Figure 1 is the deployed position, Figure 2 is the retracted position. In the deployed position, the mounting brackets 320 on both sides are opened to avoid the lifting movement of the battery tray 200. When the electrode tab 120 of the battery 210 of the battery tray 200 is pressed against the test probe of the bed body 100, the mounting bracket 320 rotates from the deployed position to the retracted position. The rotation of the mounting bracket 320 drives the air supply device 310 to directly press against the upper peripheral edge of the battery tray 200 and blow air toward the first heat dissipation hole 311, so that the distance between the air supply device 310 and the battery 210 is shorter, improving the heat dissipation efficiency.

[0025] Please refer to Figures 1 to 8, Further, a driving cylinder 400 is installed on the bed body 100. The driving cylinder 400 is drivingly connected to a moving frame 410. A support seat 411 is arranged on the moving frame 410. The mounting bracket 320 is rotatably installed on the support seat 411. A rib 321 is arranged on the mounting bracket 320. When the driving cylinder 400 drives the moving frame 410 to rise, the rib 321 can be pressed by the battery tray 200 to drive the mounting bracket 320 to rotate, so that the mounting bracket 320 is switched from the deployed position to the retracted position. Specifically, a tray support member 130 is further installed on the bed body 100. The tray support member 130 is used to support the battery tray 200. When the driving cylinder 400 of the driving cylinder 400 drives the moving frame 410 to rise, the rib 321 of the mounting bracket 320 on the moving frame 410 rises and is first pressed by the battery tray 200. As the moving frame 410 continues to rise, the rib 321 of the mounting bracket 320 is pressed by the battery tray 200 to apply pressure, causing the mounting bracket 320 to rotate until the air supply device 310 on the mounting bracket 320 is pressed against the side surface of the battery tray 200, ensuring that the air supply device 310 can directly blow air on the battery tray 200. The moving frame 410 drives the battery tray 200 and the heat dissipation assembly 300 to continue to rise until the ear 120 of the battery 210 in the battery tray 200 is pressed against the probe of the probe module 110, and then the driving cylinder 400 stops driving. After the battery 210 is charged and discharged, the driving cylinder 400 drives the moving frame 410 to descend, thereby driving the battery tray 200 and the heat dissipation assembly 300 to descend. After descending a certain distance, the battery tray 200 is supported by the tray support member 130 of the bed body 100 and stops descending. The battery tray 200 gradually loses its acting force on the rib 321 of the mounting bracket 320. At this time, the mounting bracket 320 can drive the air supply device 310 to switch from the retracted position to the deployed position. With such a setting, the automation degree of the switching of the heat dissipation assembly 300 is high. The position switching is completed by the cooperation of the mechanical structure, and there is no need to additionally set a power to drive the heat dissipation assembly 300 to switch back and forth between the deployed position and the retracted position, reducing the structural cost and improving the heat dissipation efficiency.

[0026] Please refer to Figures 1 to 8, Further, a first convex post 412 is provided on the support base 411, and a second convex post 322 is provided on the mounting bracket 320. A tension spring 413 is connected between the first convex post 412 and the second convex post 322. Under the pulling force of the tension spring 413, the mounting bracket 320 is switched from the contracted position to the deployed position. Specifically, both the first convex post 412 and the second convex post 322 are cylindrical in shape. Of course, the first convex post 412 and the second convex post 322 can also be of other shapes, as long as the connection and fixing effect of the tension spring 413 are ensured. Thus, in the initial state, the mounting bracket 320 is in the deployed position under the pulling force of the tension spring 413, and the air supply devices 310 on both sides do not press on both sides of the battery tray 200. When the driving cylinder 400 drives the moving frame 410 to rise, as the moving frame 410 rises, the rib 321 on the mounting bracket 320 of the moving frame 410 is pressed by the bottom of the battery tray 200. At this time, the tension spring 413 is in a stretched state, and the pressure exerted by the battery tray 200 on the rib 321 is greater than the pulling force of the tension spring 413, so that the mounting bracket 320 can rotate until the air supply device 310 presses on the battery tray 200 for heat dissipation blowing. The moving frame 410 drives the battery tray 200 and the heat dissipation assembly 300 to continue to rise until the ear 120 of the battery 210 in the battery tray 200 presses on the probe of the probe module 110, and the driving cylinder 400 stops driving; after the battery 210 is charged and discharged, the driving cylinder 400 drives the moving frame 410 to descend, thereby driving the battery tray 200 and the heat dissipation assembly 300 to descend. After descending a certain distance, the battery tray 200 is supported by the tray support member 130 of the bed body 100 and stops descending, while the mounting bracket 320 continues to descend. At this time, the battery tray 200 gradually loses the acting force on the rib 321 of the mounting bracket 320. Under the acting force of the tension spring, the mounting bracket 320 drives the air supply device 310 to switch from the contracted position to the deployed position.

[0027] Please refer to Figures 7 to 8 , Further, a rotating shaft 414 is provided on the support base 411, and a shaft hole 323 is provided on the mounting bracket 320. The mounting bracket 320 is rotatably connected to the support base 411 through the rotating shaft 414 passing through the shaft hole 323. Thus, the structure is stable and reliable, the cost is low, and the mounting bracket 320 can rotate relative to the support base 411, so as to realize that the air supply device 310 on the mounting bracket 320 can press on the battery tray 200.

[0028] Please refer to Figures 1 to 6, Further, the battery tray 200 has a receiving cavity 220. A plurality of support liners 221 are arranged in the receiving cavity 220. Battery card slots 222 are arranged on the support liners 221. The battery card slots 222 of any adjacent pair of support liners 221 are used to support the battery 210, and a heat dissipation air duct 211 is formed between every adjacent column of batteries 210. Specifically, the support liner 221 is a basic component for supporting the battery 210, which can make a space exist between the bottom of the battery 210 and the bottom plate of the battery tray 200, further improving the heat dissipation efficiency. At the same time, each battery 210 is arranged at intervals. The heat dissipation air duct 211 blows air between every column of batteries 210, performs heat exchange with the surfaces on both sides of the battery 210, increases the contact area between the battery 210 and the air, and takes away the heat of the battery 210, further improving the heat dissipation efficiency.

[0029] Please refer to Figures 5 to 6 , Further, a plurality of first ventilation holes 223 are formed through the side surface of the battery tray 200. Specifically, the shape of the first ventilation hole 223 can be rectangular, square or other irregular shapes, and the shapes of the respective first ventilation holes 223 can also be different. By forming countless first ventilation holes 223 through the battery tray 200, the contact area between the air flow and the battery 210 is increased, and the heat dissipation efficiency of the battery 210 is improved.

[0030] Please refer to Figure 9 , Further, a plurality of second ventilation holes 224 are formed through the support liner 221. Specifically, the shape of the second ventilation hole 224 can be rectangular, square or other irregular shapes, and the shapes of the respective second ventilation holes 224 can also be different. In this way, by designing the basic component for supporting the battery 210 to be perforated and hollowed out everywhere, the contact area between the battery 210 and the air is greatly increased, and under the action of the air supply device 310 or the external wind force, the heat dissipation efficiency of the battery 210 is greatly improved.

[0031] Please refer to Figure 5 , Further, each heat dissipation air duct 211 communicates with some of the first ventilation holes 223 and the second ventilation holes 224, so that the air flows along the side surface of the battery 210. In this way, the air can enter from the first ventilation holes 223 on one side of the battery tray 200, pass through the second ventilation holes 224, flow into the heat dissipation air duct 211, flow through the second ventilation holes 224 after flowing with the air in the heat dissipation air duct 211, enter the heat dissipation air duct 211 on the same plane, and flow out from the first ventilation holes 223 of the battery tray 200 through the second ventilation holes 224 of the support liner 221, promoting the fluidity of the air in the heat dissipation air duct 211 between two adjacent columns of batteries 210 and improving the heat dissipation efficiency of the air for the battery 210.

[0032] Please refer to Figures 1 to 8, Further, heat dissipation grooves 225 are formed by concave-convex on the side wall of the battery slot 222 of the support lining 221. In this way, by providing the heat dissipation grooves 225 on the side wall of the battery slot 222, the contact area between the battery 210 and the battery slot 222 is reduced, and then the contact area between the battery 210 and the air is increased, improving the heat dissipation efficiency of the battery 210.

[0033] Please refer to Figure 4 and Figure 6 , Further, a plurality of second heat dissipation holes 226 are opened at the bottom of the battery tray 200, and the second heat dissipation holes 226 communicate with the bottom of the heat dissipation air duct 211. Specifically, the second heat dissipation holes 226 are opened at the bottom of the battery tray 200 to communicate with the bottom of the heat dissipation air duct 211, promoting the flow of air in the heat dissipation air duct 211 and improving the heat dissipation effect of the heat dissipation air duct 211 on the side surface of the battery 210.

[0034] Please refer to Figure 4 , Further, a plurality of third heat dissipation holes 227 are also opened at the bottom of the battery tray 200, and the third heat dissipation holes 227 can be directly opposite to the battery 210. In this way, the ear 120 of the battery 210 is dissipated by the first heat dissipation hole 311, the bottom of the battery 210 is dissipated by the third heat dissipation hole 227, and the side surface of the battery 210 is dissipated by the plurality of second ventilation holes 224, the plurality of third heat dissipation holes 227 and the heat dissipation air duct 211 of the battery tray 200, realizing the heat dissipation of all surfaces of the battery 210 by the wind, increasing the contact area between the air and each surface of the battery 210, and improving the heat dissipation efficiency.

[0035] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention.
