[0045] The core of the battery is the battery cell. The consistency of the battery cell directly affects the capacity and safety of the entire battery pack. Therefore, the battery cell generally needs to undergo a charge and discharge test process during the production process. The existing battery cell discharge method is to place the battery cell in a battery cell discharge device for discharge, and then transfer the battery cell to a test station for testing after the discharge is completed. The entire discharge process of the battery cell is carried out in the battery cell discharge device, which occupies a long time for the discharge equipment, resulting in low discharge test efficiency of the battery cell.
[0046] In view of this, the utility model proposes a battery cell discharge tool and a battery cell discharge test line, aiming to solve the problem of low efficiency of current battery cell discharge test.
[0047] in, Figure 1 A structural schematic diagram of an embodiment of a battery cell discharge test line provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the battery cell discharge tooling structure; Figure 3 for Figure 1 A schematic diagram of the structure of the battery cell discharge fixture and test device; Figure 4 for Figure 1 Schematic diagram of the structure of the battery cell discharge tooling and positioning device.
[0048] See also Figure 1 and Figure 2 The battery cell discharge tool 100 includes a tool seat 1 and a discharge component 2, wherein the tool seat 1 is formed with a placement area, and the placement area is used to place the test battery cell 100a; the discharge component 2 includes a power connection part 21 and a power consumption part 22, and the power consumption part 22 is arranged on the tool seat 1, and the power connection part 21 is electrically connected to the power consumption part 22, and is movably arranged in the height direction of the tool seat 1, so as to have a first position and a second position close to and away from the placement area in its movable stroke; when in the first position, the power connection part 21 can be connected to the positive and negative poles of the test battery cell 100a, so as to form a power circuit with the power consumption part 22.
[0049] It should be noted that the placement area corresponds to the position of the power connection part 21, that is, it is necessary to ensure that after the test battery 100a is correctly placed in the placement area, the power connection part 21 can accurately conduct and contact the positive and negative poles of the test battery 100a during its movement range; at the same time, since the power connection part 21 conducts and contacts the positive and negative poles of the test battery 100a, the power consumption part 22 can form a power-on circuit. It can be understood that the power connection part 21 is made of conductive material and is at least in two sections, so as to be respectively conducted with the positive pole of the test battery 100a and the positive and negative poles of the power consumption part 22. The specific material of the power connection part 21 can be copper or iron, and this application does not limit this; at the same time, the function of the power consumption part 22 is to consume the electrical energy in the test battery 100a. As long as it is an electrical device, it belongs to the protection scope of the power consumption part 22. This embodiment does not limit the specific structure of the power consumption part 22.
[0050] In the technical solution provided by the present invention, after the test battery cell 100a is placed into the accommodating portion, the discharge device drives the power connection portion 21 to move to the first position, thereby connecting the test battery cell 100a and the power consumption portion 22, so that the power consumption portion 22 continuously consumes the electric energy in the test battery cell 100a to achieve the purpose of discharge, and the entire discharge process is completed inside the battery cell discharge fixture 100 without the participation of external structures. Therefore, after the discharge device drives the power connection portion 21 to move to the first position, the battery cell discharge fixture 100 can carry the test battery cell 100a as a whole to the downstream testing process without occupying too much discharge equipment, thereby greatly improving the discharge test efficiency.
[0051] There are differences in power consumption between different electrical devices, but given that the use scenario of the battery cell discharge tool 100 provided in this application is for the discharge of battery cells, higher power consumption means an improvement in the discharge test efficiency for the battery cells. In view of this, in some embodiments, the power consumption unit 22 includes a heating tube 22a. Since the heating tube 22a is an electric heating component, its power consumption process is the process of converting electrical energy into thermal energy. Under the same circumstances, the power consumption of the electric heating component is higher than that of other components such as optoelectronic components. Therefore, using the heating tube 22a as the power consumption unit 22 can quickly consume the electrical energy in the test battery cell 100a, that is, it can improve the discharge test efficiency.
[0052] Since the heating tube 22a generates a large amount of heat during the discharge process, if the heating tube 22a is not cooled in time, the service life of the heating tube 22a may be reduced or even damaged. In view of this, please refer to Figure 1 and Figure 2In some embodiments, a mounting rod 12 is provided on the tooling seat 1, and the mounting rod 12 has a hanging section 121 extending along the height direction; the heating tube 22a is arranged in the hanging section 121. It should be noted that the mounting rod 12 can be set as a straight rod or a curved rod, as long as there is a hanging section 121 extending in the height direction in its local section, and the hanging section 121 refers to the hanging section 121 hanging toward the bottom of the tooling seat 1 in the section where the mounting rod 12 extends from the tooling seat 1 to its end. With such a configuration, during the transportation process of the battery cell discharge tool 100, the hanging section 121 can extend the heating tube 22a into the cooling liquid tank 600, so as to assist the heating part to dissipate heat through the cooling liquid, thereby ensuring the stable operation of the heating tube 22a.
[0053] See also Figure 2 and 4 In some embodiments, the battery cell discharge tooling 100 further includes a limiting structure 11 and a loading frame 5, wherein the limiting structure 11 is arranged around the placement area and forms a material transfer channel opened on one side in the width direction of the tooling seat 1; the loading frame 5 can be loaded into the placement area through the material transfer channel, and the loading frame 5 is used for placing the test battery cell 100a.
[0054] It should be noted that the function of the loading frame 5 is to load the test battery cell 100a, which can be specifically loaded with one, of course, it can also be loaded with multiple, and the present application does not limit the loading capacity of the loading frame 5. At the same time, the loading frame 5 can ensure that the positive and negative electrodes of the test battery cell 100a are exposed toward the power connection part 21; the function of the limiting structure 11 is to limit the loading frame 5 in the placement area to prevent its position from being placed incorrectly and causing subsequent discharge failure. The limiting structure 11 can be set continuously or in segments, as long as the surrounding side of the placement area can form a barrier to the loading frame 5. Since the limiting structure 11 forms a passing channel, the loading frame 5 can enter the placement area through the passing channel, which can improve the placement efficiency of the test battery cell 100a.
[0055] For further information, see Figure 4In some embodiments, the limiting structure 11 includes two roller assemblies 111, which are opposite to each other along the length direction of the tooling seat 1 and are respectively arranged on the corresponding two sides of the placement area; the roller assembly 111 includes a plurality of guide rollers 111a, which are arranged along the width direction and rotate along the axis in the height direction. According to the above technical solution, the two roller assemblies 111 play a limiting role. Due to the existence of the guide rollers 111a, the guide rollers 111a can contact the load and rotate to unload the force, so that the loading frame 5 is smoother in the process of passing through the material transfer channel into the loading area, thereby improving the placement efficiency of the test battery cell 100a.
[0056] The power connection part 21 has various ways of moving in the height direction of the tooling seat 1. Figure 1 In some embodiments, a guide portion 31 extending along the height direction is formed on the tooling seat 1; the battery cell discharge tooling 100 also includes a movable mounting structure 4, a matching portion 32 is formed on the movable mounting structure 4, and the matching portion 32 is adapted to be arranged on the guide portion 31 so that the position of the movable mounting structure 4 in the height direction is adjustable; the power connection portion 21 is arranged on the movable mounting structure 4.
[0057] It should be noted that there are various ways of connecting the matching portion 32 and the guide portion 31. For example, in one case, the guide portion 31 includes a guide rod, and the matching portion 32 includes a sleeve, and the sleeve is sleeved on the guide rod to achieve guidance. In another case, the guide portion 31 includes a guide rail, and the matching portion 32 includes a slider, and the slider is slidably arranged on the slide rail to achieve guidance.
[0058] According to the above technical solution, through the guiding cooperation between the guide portion 31 and the matching portion 32, the matching portion 32 can limit the moving trajectory of the movable mounting structure 4, and the power connection portion 21 is arranged on the movable mounting structure 4, which can ensure the consistency of the moving trajectory of the power connection portion 21 and ensure the accurate contact between the power connection portion 21 and the electrode of the test battery cell 100a.
[0059] Furthermore, in some embodiments, the guide portion 31 and the matching portion 32 correspond to each other to form a guide group 3, and a plurality of guide groups 3 are arranged around the placement area. Since the power connection portion 21 is arranged corresponding to the test battery cell 100a, that is, corresponding to the placement area, by arranging a plurality of guide groups 3 around the placement area, the movable mounting structure 4 can be guided on the peripheral side thereof, which plays a role in force balance, and avoids the matching portion 32 in a single guide group 3 from bearing the torsional force from the movable mounting structure 4, thereby ensuring the smooth movement of the movable mounting structure 4 along the height direction.
[0060] In some embodiments, the tool holder 1 is provided with a matching recess toward the height direction, and the matching recess is used for plugging and connecting the external positioning protrusion 310. In this way, by providing the matching recess, when the battery cell discharge tool 100 reaches the corresponding discharge station or test station on the conveyor line 200, it can be kept in the expected position under the plugging action of the positioning protrusion 310 of the corresponding station and the matching part 32 of the tool holder 1, which is conducive to the subsequent discharge drive device 500 accurately driving the power connection part 21 to move or the test device 400 accurately conducting to the power connection part 21, reducing the error probability of the battery cell discharge test line 1000.
[0061] See also Figure 3 In some embodiments, the tool holder 1 is further provided with a test portion 23, the test portion 23 is electrically connected to the power connection portion 21, and the test portion 23 is used for conducting connection with an external movable probe 410. Since the test portion 23 can be conducted with the power connection portion 21 and is located at a fixed position on the tool holder 1, when the battery cell discharge tool 100 arrives at the test station, the movable probe 410 at the test station can accurately contact and conduct to the test portion 23, thereby detecting whether the test battery cell 100a is fully discharged.
[0062] In addition, to achieve the above purpose, please refer to Figure 1 The utility model also provides a battery cell discharge test line 1000, which has at least a discharge station and a test station. The battery cell discharge test line 1000 includes a conveyor line 200 and a plurality of battery cell discharge fixtures 100 described in the above technical solution. The conveyor line 200 is arranged in a rotating manner and passes through the discharge station and the test station. A plurality of battery cell discharge fixtures 100 are arranged on the conveyor line 200. On the conveying stroke of the conveyor line 200, the battery cell discharge fixture 100 can pass through the discharge station and the test station in sequence, and the power connection part 21 can be driven to the first position at the discharge station.
[0063] It should be noted that the detailed structure of the battery cell discharge tooling 100 of the battery cell discharge test line 1000 can refer to the above-mentioned embodiment of the battery cell discharge tooling 100, which will not be repeated here; since the above-mentioned battery cell discharge tooling 100 is used in the battery cell discharge test line 1000 of the utility model, the embodiment of the battery cell discharge test line 1000 of the utility model includes all technical solutions of all embodiments of the above-mentioned battery cell discharge tooling 100, and the technical effects achieved are also exactly the same, which will not be repeated here.
[0064] It should be noted that in Figure 1 In order to facilitate the display, only a partial section of the conveyor line 200 is intercepted.

After that, the conveyor line 200 can transport the battery cell discharge fixture 100 toward the test station. During the transportation process, the test battery 100a can keep discharging. After arriving at the test station, the test battery 100a can be tested by a testing device 400 or manually. After the test is completed, the power connection part 21 can be driven to the second position by a driving device or manually, and the test battery 100a can be removed from the battery cell discharge fixture 100 by a unloading structure or manually, and a new test battery 100a can be loaded into the battery cell discharge fixture 100 by a loading structure or manually. Finally, under the rotary transportation of the conveyor line 200, the battery cell discharge fixture 100 can repeatedly pass through the discharge station and the test station.

[0067] According to the above technical scheme, by setting the matching recess, when the battery cell discharge tooling 100 reaches the corresponding discharge station or test station on the conveyor line 200, it can be maintained in the expected position under the plug-in action of the positioning protrusion 310 of the corresponding positioning device 300 and the matching portion 32 of the tooling seat 1, which is conducive to the subsequent discharge driving device 500 accurately driving the power connection part 21 to move or the test device 400 accurately conducting to the power connection part 21, thereby reducing the error probability of the battery cell discharge test line 1000.
[0068] See also Figure 1 and Figure 2 In some embodiments, the battery cell discharge test line 1000 also includes a cooling liquid tank 600, and the cooling liquid tank 600 is arranged in a rotation corresponding to the conveying line 200; a mounting rod 12 is arranged on the tooling seat 1, and the mounting rod 12 has a hanging section 121 extending along the height direction, and the hanging section 121 extends into the cooling liquid tank 600; the power consumption part 22 includes a heating tube 22a, and the heating tube 22a is arranged in the hanging section 121.
[0069] Similarly, in Figure 1 In order to facilitate the display, only a partial section of the cooling liquid tank 600 is intercepted. Since it has been clearly defined in the above technical solution that the cooling liquid tank 600 is in a rotary setting, in the actual product of the cooling liquid tank 600, it is in a rotary setting.
