[0031] The clamping assembly 7 is installed on the sub-capacity box 5;

[0032] There are a plurality of needle bed assemblies 8 , which are evenly installed in the sub-volume chamber 101 and located directly above the corresponding pull-out racks 3 .

[0033] It should be noted that: during use, when it is necessary to clamp the test battery, according to the battery model on the market, after the pull-out rack 3 is pulled out from the guide rail 2, the two-way threaded rod 63 is twisted. When the two-way threaded rod 63 rotates, the two transmission blocks 64 are driven to move closer to or away from each other, so that the transmission rod 65 drives the middle block 66 to drive the two L-shaped clamps 62 closer to or away from each other by using the connecting spring 67, so as to adjust the spacing between the two L-shaped clamps 62 to make it compatible with the battery model on the market, so as to facilitate clamping the battery in the sub-capacity box 5. After placement, it is further clamped by the clamping assembly 7.

[0034] It should also be noted that: the capacity division cabinet body 1 here is a capacity division cabinet commonly used in the prior art, and is internally integrated with equipment and controllers that can set the voltage and current of battery charging and discharging, perform constant current charging and discharging of the battery according to the set charging and discharging parameters, group the batteries and perform capacity verification according to the set capacity, and perform cyclic charging and discharging of the batteries according to the set number of cycles. The specific structure and working principle will not be described in detail here. These devices and controllers are electrically connected to the needle bed assembly 8 to achieve connection with the battery, thereby performing capacity division testing.

[0035] In the embodiments of the present invention, please refer to Figure 1 and Figure 3The temperature control box 4 includes a box body 41, which is embedded in the bottom end of the pull-out frame 3, and a thermostat 42 is embedded in the outer wall of the box body 41, and the thermostat 42 is electrically connected to a constant temperature heating plate 43 and a cooling fan 44, and the constant temperature heating plate 43 is embedded in the bottom of the inner cavity of the box body 41, and a plurality of cooling fans 44 are provided, and the plurality of cooling fans 44 are embedded in the through holes opened in the side wall of the box body 41;

[0036] The temperature sensor of the thermostat 42 is embedded in the box 41 .

[0037] It should be noted that: when the battery is subjected to capacity testing, when the internal temperature needs to be heated, the constant temperature heating plate 43 is started by the thermostat 42 to heat the battery to the set temperature. When cooling and heat dissipation are required, the cooling fan 44 is started to perform air cooling and heat dissipation, thereby facilitating the adjustment of the ambient temperature of the battery test.

[0038] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 The clamp assembly 7 includes an L-shaped curved tube 71, two L-shaped curved tubes 71 are provided, and the two L-shaped curved tubes 71 are symmetrically inserted on one side of the top plate of the sub-capacity box 5, and the two L-shaped curved tubes 71 are rotatably connected to the clamp curved tube 72, and the outer wall of the L-shaped curved tube 71 is fixedly installed with a limit spring 73, and one end of the limit spring 73 away from the L-shaped curved tube 71 is fixedly connected to the outer wall of the clamp curved tube 72, and the bottom ends of the two L-shaped curved tubes 71 are fixedly installed with a horizontal plate 74, and the middle part of the horizontal plate 74 is fixedly installed with a screw 75, and the screw 75 is disassembled and installed on the top plate of the sub-capacity box 5 by screw opening;

[0039] The top plate of the volume dividing box 5 is provided with a through hole through which the screw rod 75 passes.

[0040] It should be noted that when the clamping assembly 7 is in use, when the battery is pressed and fixed in the storage box 5, the clamping elbow 72 is flipped over to clamp the battery. The clamping elbow 72 presses the battery into the storage box 5 under the pull of the limit spring 73. The tightness of the clamping can be achieved by adjusting the extension length of the screw 75 in the storage box 5. Specifically, locking nuts are screwed on both sides of the through hole opened in the top plate of the storage box 5 through which the screw 75 passes. The extension length is adjusted by screwing the two locking nuts, thereby adjusting the tightening force, which is convenient for stabilizing the clamping. When it needs to be taken out, the clamping elbow 72 can be flipped over.

[0041] In the embodiments of the present invention, please refer to Figure 1 , Figure 6 and Figure 7The needle bed assembly 8 includes a layer plate 81, which is installed in the sub-volume chamber 101 and is located above the corresponding pull-out frame 3, and a through slot is opened in the middle of the layer plate 81, and electric telescopic rods 82 are fixedly installed at the four corners of the through slot, and a test needle bed 83 is fixedly installed at the telescopic ends of the four electric telescopic rods 82.

[0042] It should be noted that when the needle bed assembly 8 is in use, after the battery is installed in the capacity dividing box 5 and pushed into the capacity dividing chamber 101, the electric telescopic rod 82 is controlled to drive the test needle bed 83 to approach the battery and make electrical contact with the battery to perform a capacity dividing test. Here, the test needle bed 83 is designed according to the electrode position of the battery to achieve downward movement and electrical connection.

[0043] The working principle of the chemical separation cabinet provided by the utility model is as follows:

[0044] When in use, when it is necessary to clamp the test battery, according to the battery model on the market, after the pull-out frame 3 is pulled out from the guide rail 2, the two-way threaded rod 63 is twisted. When the two-way threaded rod 63 rotates, the two transmission blocks 64 are driven to move closer to or away from each other, so that the transmission rod 65 drives the middle block 66 to drive the two L-shaped clamping plates 62 closer to or away from each other by using the connecting spring 67, so as to adjust the distance between the two L-shaped clamping plates 62, so as to adapt it to the battery model on the market, so as to facilitate the battery clamping in the sub-capacity box 5, and after placing it, flip it over. The clamping elbow 72 is clamped on the top of the battery. The clamping elbow 72 presses the battery into the sub-capacity box 5 under the pull of the limit spring 73. The tightness of the clamping can be achieved by adjusting the extension length of the screw 75 in the sub-capacity box 5. Specifically, locking nuts are screwed on both sides of the through hole opened in the top plate of the sub-capacity box 5 through the screw 75. The extension length is adjusted by screwing the two locking nuts, thereby adjusting the tightening force, which is convenient for stable clamping. When it needs to be taken out, the clamping elbow 72 can be turned over. The whole battery clamping is very convenient and has high clamping versatility.

[0045] After the battery is installed in the capacity division box 5 and pushed into the capacity division chamber 101, the electric telescopic rod 82 is controlled to drive the test needle bed 83 to approach the battery and make electrical contact with the battery, so as to perform the capacity division test. During the test, when it is necessary to heat the internal temperature, the constant temperature heating plate 43 is started by the thermostat 42 to heat to the set temperature. When cooling and heat dissipation are required, the cooling fan 44 is controlled to start for air cooling and heat dissipation, thereby facilitating the adjustment of the ambient temperature of the battery test.

[0046] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
