[0001] Cross-references to related applications

[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202510069382.1, filed on January 16, 2025, entitled “A Testing Device and Battery Voltage Withstand Test System”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of battery testing technology, and in particular to a testing device and a battery withstand voltage testing system. Background Technology

[0004] During battery production, individual battery cells typically require testing, such as withstand voltage tests using electrical equipment, to determine if their insulation and withstand voltage performance meet requirements. However, related technologies suffer from low testing efficiency, impacting production cycle time. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this disclosure is to provide a testing device and a battery withstand voltage testing system.

[0006] The first aspect of this disclosure provides a testing apparatus, including a testing turret. The testing turret has an inlet side and an outlet side. The testing turret includes a testing turntable and a testing component. The testing turntable is used to transfer a support cup between the inlet side and the outlet side. The support cup is used to carry individual battery cells. The testing component is connected to the testing turntable and moves synchronously with the testing turntable. The testing component and the testing turntable are relatively stationary along the direction of movement. The testing component is used to test the individual battery cells in the testing turntable.

[0007] In the technical solution provided by this disclosure, the test turret includes a test turntable and a test component. The test turntable can drive the cup to move from the feeding side to the discharging side, thereby realizing the transfer of the cup and the corresponding battery cell. The test component is connected to the test turntable and moves synchronously with it. That is, the test component moves synchronously with the cup and battery cell on the test turntable, and the test component and battery cell can remain relatively stationary. While the test turntable is transferring the battery, the test component can test the battery cell. This testing process does not require pausing the cup and battery cell, ensuring the continuity of the battery cell transfer process. Furthermore, the transfer and testing are carried out simultaneously, saving time and thus accelerating the production cycle of the battery cell and improving production efficiency. Compared with related technologies where battery cells need to be paused before testing, the test component of this disclosure moves synchronously with the test turntable, performing testing while the battery cell is being transferred, saving testing time, accelerating the production cycle, and improving production efficiency.

[0008] In some embodiments of this disclosure, the test turret further includes a turret shaft and a lifting assembly. The lifting assembly and the test turntable are coaxially connected to the turret shaft, and the test assembly is connected to the lifting assembly. The lifting assembly is used to move the test assembly closer to or away from the test turntable.

[0009] Here, by setting up a lifting component, the lifting component can drive the test component to move. During the process of transporting the battery cell into or out of the test turntable, the lifting component moves the test component away from the battery cell, reducing the possibility of collision between the test component and the battery cell. When testing is required, the lifting component moves the test component closer to the battery cell so that the test component can test the battery cell, which not only facilitates testing but also protects the test component and the battery cell.

[0010] In some embodiments of this disclosure, the lifting assembly includes a connector that connects to the test assembly and the turret shaft respectively, and the connector is rotatably arranged relative to the turret shaft; or, the connector is translatably arranged relative to the turret shaft.

[0011] Here, by setting a connector that rotates relative to the turret shaft to form a lever structure, the test component can be driven to move up and down along the axial direction of the turret shaft, as well as to move the test component radially along the turret shaft; the connector can also be translated relative to the turret shaft to drive the test component to move up and down, making the structure simpler.

[0012] In some embodiments of this disclosure, the lifting assembly further includes a track component, which is coaxially connected to the turret shaft and rotates relative to it. The track component is provided with a circumferentially surrounding track. The track includes at least two track segments along the axial direction of the turret shaft. The at least two track segments are spaced differently from the test turntable. The connecting member rotates with the turret shaft and moves along the track to drive the test assembly closer to or away from the test turntable.

[0013] Here, by setting up a track component with a track, the connector will also move along the track as the connector rotates with the turret shaft. Since the track includes at least two track segments with different distances from the test turntable, the connector will rise or fall in the corresponding track segment, thereby driving the test component to rise and fall. Since the rise and fall of the test component is related to the rotation of the test turntable, it has high matching accuracy.

[0014] In some embodiments of this disclosure, at least two track segments include a separation segment, a test segment, and a connecting segment connecting the separation segment and the test segment. Along the axial direction of the turret shaft, a first distance between the separation segment and the test turntable is greater than a second distance between the test segment and the test turntable. When the connecting segment moves to the test segment, the test component comes into contact with the battery cell at the corresponding position.

[0015] Here, by setting up a separation section and a test section, the connecting piece can be moved to the separation section to lift the test component, so as to facilitate the transport of battery cells in and out; the connecting piece can be moved to the test section to bring the test component into contact with the battery cells, so as to facilitate the testing of the test component.

[0016] In some embodiments of this disclosure, the test section has a first dimension along the circumference of the track member, and the separation section has a second dimension along the circumference of the track member, wherein the first dimension is larger than the second dimension.

[0017] Here, because the first dimension of the test section is larger than the second dimension of the separation section, the test component can have more time to contact the battery cell, which facilitates the test.

[0018] In some embodiments of this disclosure, the lifting assembly further includes a rotating member, the track is a track groove formed on the outer periphery of the track member, the rotating member is rotatably disposed in the track groove, and the connecting member is connected to the rotating member.

[0019] Here, the track is in the form of a track groove, which can limit the rotation of the rotating parts to improve the guiding accuracy. The rotating parts can also reduce friction so that the connecting parts can move smoothly along the track.

[0020] In some embodiments of this disclosure, the test turret further includes a support member disposed between the track member and the test turntable, and fixedly disposed relative to the turret axis, with a connecting member movably connected to the outer periphery of the support member.

[0021] Here, a support is provided for the sliding connection of the connector. Since the support has a large radial dimension relative to the turret shaft, it can provide better support for the connector and also provide a large space for movement of the test component.

[0022] In some embodiments of this disclosure, the support includes a support plate and a support sleeve. The support plate is fixed to the turret shaft, the support sleeve is sleeved on the outer periphery of the support plate, and the connecting member is movably connected to the support sleeve. Along the axial direction of the turret shaft, the size of the support sleeve is larger than the size of the support plate.

[0023] Here, the support is set as two parts: a support plate and a support sleeve. The support sleeve can provide a larger support size to facilitate the stable connection of the connectors, and the axial dimension of the support plate is small, which also helps to reduce weight.

[0024] In some embodiments of this disclosure, the test turret further includes a guide assembly, which includes a guide member and a sliding member. The guide member is connected to the outer periphery of the support member, the sliding member is connected to the guide member and moves along the guide member, the connecting member is connected to the sliding member, and the support sleeve extends to both ends of the guide member along the movement direction of the sliding member.

[0025] Here, by setting a guide component, the slide rail of the guide component is connected to the support sleeve, and the support sleeve extends to both ends of the guide component, which can provide stable support for the guide component. The connecting component is connected to the guide component through the sliding component, and under the guidance of the guide component, it can move smoothly in a preset direction.

[0026] In some embodiments of this disclosure, the test turret further includes a locking assembly connected to the slider. The locking assembly includes at least two relatively movable locking portions for locking and securing the connector.

[0027] Here, by setting up a locking component, the locking component locks and fixes the connector through the locking part, which facilitates the disassembly and assembly of the connector relative to the guide component, so as to facilitate the maintenance of the test component, test turntable, etc.

[0028] In some embodiments of this disclosure, the test turntable includes a receiving slot for accommodating a cup, there are at least two receiving slots, and at least some of the receiving slots are correspondingly provided with test components.

[0029] Here, by setting at least two receiving slots, the test turntable can transfer multiple battery cells simultaneously, and at least two test components can test multiple battery cells on the test turntable, thereby improving the testing efficiency.

[0030] In some embodiments of this disclosure, the testing apparatus further includes a power transmission mechanism, which includes a first ring body, a second ring body, and a conductive wire harness. The first ring body and the second ring body rotate relative to each other and are electrically connected. The second ring body is fixed relative to the test turntable, and the conductive wire harness is connected between the second ring body and the test component.

[0031] Here, by setting up a power transmission mechanism, which includes a first ring and a second ring that are electrically connected, the second ring is connected to the test component through a conductive wire harness and can rotate synchronously to avoid the guide wire harness from getting tangled during rotation, thus optimizing the electrical connection method of the test component.

[0032] In some embodiments of this disclosure, the test assembly includes a test probe and an adapter. The adapter has a defined extension direction, and the dimension of the adapter along the extension direction is larger than the dimension of the adapter along the other directions. The two ends of the adapter along its extension direction are respectively connected to the test probe and the test turntable.

[0033] Here, by setting up an adapter, the test probe is connected to one end of the adapter, which is less likely to interfere with other parts of the test turret and facilitates the connection of the test probe.

[0034] In some embodiments of this disclosure, the test turntable is configured to face the diameter direction of the adapter, and the extension direction of the adapter is set at an angle to the corresponding diameter direction.

[0035] Here, the extension direction of the adapter is set at an angle to the corresponding diameter direction, which allows the enclosing size of multiple adapters to be set smaller, thus making the structure of the test turret more compact.

[0036] The second aspect of this disclosure provides a battery withstand voltage testing system, including production equipment, transportation equipment, and a testing device according to the first aspect. The production equipment is used to produce battery cells; the testing device is used to perform withstand voltage tests on the battery cells; and the transportation equipment is disposed between the production equipment and the testing device for transporting the battery cells.

[0037] In the technical solution of this disclosure embodiment, the battery withstand voltage testing system includes the above-mentioned testing device. The testing component is connected to the testing turntable and moves synchronously with the testing turntable. That is, the testing component moves synchronously with the cup and battery cell on the testing turntable. The testing component and the battery cell can remain relatively stationary. While the testing turntable is transferring the battery, the testing component can test the battery cell. This testing process does not require pausing the cup and battery cell, ensuring the continuity of the battery cell transfer process. Moreover, the transfer and testing are carried out simultaneously, which can save testing time and optimize the production cycle. Attached Figure Description

[0062] The following is a detailed description of this disclosure.

[0063] Batteries are being used more and more widely in daily life and industry. They are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles and electric cars, as well as in aerospace and many other fields.

[0064] During battery production, individual battery cells typically require testing, such as withstand voltage tests using electrical equipment, to determine if their insulation and withstand voltage meet requirements. Since battery cells are transported on the logistics line, testing takes time. Usually, moving battery cells are stopped and released only after testing is complete. This affects the transport cycle of battery cells, thus impacting the production line's efficiency.

[0065] To address the aforementioned technical problems, this disclosure provides a testing device in which a testing component is connected to a testing turntable and rotates synchronously with it. That is, the testing component moves synchronously with the cup and battery cell on the testing turntable, and the testing component and battery cell remain relatively stationary. While the testing turntable transports the battery, the testing component can test the battery cell. This testing process does not require pausing the cup and battery cell, ensuring the continuity of the battery cell transport process. Furthermore, the transport and testing are performed simultaneously, saving time and accelerating the battery cell production cycle, thereby improving production efficiency. A detailed description is provided below with reference to the accompanying drawings.

[0066] Referring to Figures 1 and 2, the testing apparatus of this embodiment includes a testing turret 100, which has a feed side and a discharge side. The testing turret 100 includes a testing turntable 110 and a testing component 120. The testing turntable 110 is used to transfer a cup 600 between the feed side and the discharge side, and the cup 600 is used to carry a battery cell 700. The testing component 120 is connected to the testing turntable 110 and moves synchronously with the testing turntable 110. The testing component 120 and the testing turntable 110 are relatively stationary along the direction of movement. The testing component 120 is used to test the battery cell 700 in the testing turntable 110.

[0067] In this embodiment, the cup 600 moves along with the test turntable 110, thus moving from the feed side to the discharge side of the test turret 100, and is used to carry the battery cells 700. The inner contour of the cup 600 can be set according to the outer contour of the battery cell 700, for example, it can be set to a cylindrical shape to accommodate cylindrical batteries, or a square shape to accommodate square batteries. The outer contour of the cup 600 can be set to a circle, a square, an ellipse, etc. For example, the outer contour of the cup 600 is set to a circle, which has strong impact resistance and is also convenient for switching to different turntables.

[0068] In this embodiment of the disclosure, synchronous movement refers to the test component 120 and the test turntable 110 moving at the same speed and direction at the same time. The movement of the test component 120 following the test turntable 110 can be a rotational motion about a fixed axis, a reciprocating motion along a single trajectory, or a cyclic motion along a circular trajectory.

[0069] In this embodiment, the test component 120 and the test turntable 110 are relatively stationary along the movement direction. Specifically, as the test turntable 110 moves along the movement trajectory, the test component 120 also moves along the same trajectory, with their positions and speeds corresponding to each other, thus remaining relatively stationary along the trajectory. Furthermore, the test component 120 can also move in other directions, such as moving closer to or further away from the test turntable 110.

[0070] When the test assembly 120 rotates following the test turntable 110, the test assembly 120 and the test turntable 110 have the same axis of rotation (i.e., their axes overlap) and move at the same angular velocity to remain relatively stationary. For example, the test assembly 120 and the test turntable 110 rotate at the same angular velocity, allowing the test assembly 120 to remain stationary relative to the test turntable 110, thereby keeping the test assembly 120 stationary relative to the corresponding battery cell 700. The test assembly 120 and the test turntable 110 can be directly or indirectly connected.

[0071] In the technical solution provided by this embodiment, the test turret 100 includes a test turntable 110 and a test component 120. The test turntable 110 can drive the cup 600 from the feeding side to the discharging side to realize the transfer of the cup 600 and the corresponding battery cell 700. The test component 120 is connected to the test turntable 110 and moves synchronously with the test turntable 110. That is, the test component 120 moves synchronously with the cup 600 and the battery cell 700 on the test turntable 110. The test component 120 and the battery cell 700 can remain relatively stationary. While the test turntable 110 is transferring the battery, the test component 120 can test the battery cell 700. This testing process does not require pausing the cup 600 and the battery cell 700, ensuring the continuity of the battery cell 700 transfer process. Moreover, the transfer and testing are carried out simultaneously, saving time and thus speeding up the production cycle of the battery cell 700 and improving production efficiency.

[0072] Compared with related technologies where the battery cell 700 needs to be paused before testing, the test assembly 120 of this disclosure moves synchronously with the test turntable 110 and performs testing while the battery cell 700 is being transported, saving testing time, speeding up the production cycle, and improving production efficiency.

[0073] To protect the test assembly 120 and the battery cell 700, referring to Figures 3 and 4, in some possible embodiments of this disclosure, the test turret 100 further includes a turret shaft 130 and a lifting assembly 140. The lifting assembly 140 and the test turntable 110 are coaxially connected to the turret shaft 130, and the test assembly 120 is connected to the lifting assembly 140. The lifting assembly 140 is used to move the test assembly 120 closer to or away from the test turntable 110.

[0074] In this embodiment, the turret shaft 130 is used to support the test turntable 110, the lifting assembly 140, the test assembly 120, etc. It is understood that the test turntable 110 and the lifting assembly 140 rotate synchronously through the turret shaft 130. For example, the test turntable 110 is sleeved and fixedly connected to the outer periphery of the turret shaft 130, and the test turntable 110 rotates coaxially with the turret shaft 130; the lifting assembly 140 is connected to the turret shaft 130, and there is a circumferential limit between the two, so that the turret shaft 130 drives the lifting assembly 140 to rotate, thereby driving the test assembly 120 connected to the lifting assembly 140 to rotate.

[0075] In this embodiment, the connection between the lifting assembly 140 and the turret shaft 130 can be a fixed connection or a movable connection, such as a sliding connection or a hinge. The lifting assembly 140 can be active, that is, the lifting assembly 140 includes a driving component, which drives the test assembly 120 to move; or, the lifting assembly 140 cooperates with the rotation of the turret shaft 130, and the rotation of the turret shaft 130 drives the test assembly 120 to move.

[0076] In this embodiment of the disclosure, the axis of the turret shaft 130 is set parallel to the preset direction X. The movement of the test component 120 toward or away from the test turntable 110 can be along the preset direction X or at an angle to the preset direction X. In other words, the test component 120 has a component along the preset direction X during the movement. For example, when the lifting component 140 drives the test component 120 to rotate perpendicular to the turret shaft 130, the test component 120 moves both along the axial direction of the turret shaft 130 and along the radial direction of the turret shaft 130.

[0077] The technical solution of this embodiment of the disclosure, by setting up a lifting component 140, can drive the test component 120 to move. During the process of the battery cell 700 being transported into or out of the test turntable 110, the lifting component 140 drives the test component 120 away from the battery cell 700, reducing the possibility of collision between the test component 120 and the battery cell 700. When testing is required, the lifting component 140 drives the test component 120 closer to the battery cell 700 so that the test component 120 can test the battery cell 700, which not only facilitates testing but also protects the test component 120 and the battery cell 700.

[0078] To facilitate the lifting and lowering movement of the test component 120, referring to Figures 3 and 4, in some possible embodiments of this disclosure, the lifting component 140 includes a connector 141, which connects the test component 120 and the turret shaft 130 respectively. The connector 141 is rotatably arranged relative to the turret shaft 130; or, the connector 141 is translatably arranged relative to the turret shaft.

[0079] In this embodiment, the connector 141 and the turret shaft 130 are rotatably arranged relative to each other. Specifically, the two are rotatably connected by a shaft, bearing, etc., or by a transmission connection through gears, worm gears, etc. The connector 141 and the turret shaft 130 can rotate relative to each other, thereby changing the distance between the end of the connector 141 and the test turntable 110.

[0080] In this embodiment of the disclosure, the portion of the connector 141 rotatably connected to the turret shaft 130 may be the middle or the end. In one example, one end of the connector 141 is rotatably connected to the turret shaft 130, and the other end is connected to the test assembly 120. In another example, the middle portion of the connector 141 is rotatably connected to the turret shaft 130, and the end of the connector 141 near the test turntable 110 is connected to the test assembly 120.

[0081] In this embodiment, the connector 141 and the turret shaft 130 are arranged in a relatively translatable manner. Specifically, the two are slidably connected by a slide groove, guide rail, linear bearing, etc., or they are connected by a transmission mechanism such as a linkage. The connector 141 moves along the axis of the turret shaft 130, thereby changing the distance between the end of the connector 141 and the test turntable 110.

[0082] In this embodiment, the connector 141 can be slidably connected to the turret shaft 130, either by direct sliding or by a groove formed in the turret shaft 130, with a portion of the connector 141 extending into the groove. Alternatively, the connector 141 and the turret shaft 130 can be slidably connected via a guide, a slider, or the like. It should be noted that the slidable connection can restrict the radial movement of the connector 141 along the turret shaft 130.

[0083] In this embodiment of the disclosure, the connection between the test component 120 and the connector 141 can be a movable connection, such as a sliding connection, a hinge, or a flexible connection; the connection between the test component 120 and the connector 141 can also be a fixed connection, such as a snap-fit, adhesive bonding, welding, riveting, or fastener connection. For example, the end of the connector 141 closest to the test turntable 110 is fixedly connected to the test component 120.

[0084] The technical solution of this disclosure embodiment, by setting a connector 141, the connector 141 is rotatably arranged relative to the turret shaft 130 to form a lever structure, which can drive the test component 120 to move up and down along the axial direction of the turret shaft 130, and can also drive the test component 120 to move radially along the turret shaft 130; the connector 141 can also be arranged to translate relative to the turret shaft 130 to drive the test component 120 to move up and down, making the structure simpler.

[0085] To adapt the lifting of the test assembly 120 to the rotation of the test turntable 110, referring to Figures 3, 4 and 5, in some possible embodiments of this disclosure, the lifting assembly 140 further includes a track component 142. The track component 142 is coaxially connected to the turret shaft 130 and is rotatably arranged relative to it. The track component 142 is provided with a circumferentially surrounding track 143. The track 143 includes at least two track segments along the axial direction of the turret shaft 130. The at least two track segments are spaced differently from the test turntable 110. The connecting member 141 rotates with the turret shaft 130 and moves along the track 143 to drive the test assembly 120 closer to or away from the test turntable 110.

[0086] In this embodiment, the track component 142 is coaxially arranged with the turret shaft 130 and rotates relative to it. That is, the track component 142 does not rotate with the turret shaft 130, and the track component 142 can be fixed to the base of the testing device. Due to the relative movement between the two, as the turret shaft 130 drives the connecting component 141 to rotate, the connecting component 141 will move relative to the track component 142.

[0087] In this embodiment, the track component 142 is a disc structure, and the track 143 can be disposed on the outer periphery of the track component 142, or on the upper or lower surface of the track component 142 along a predetermined direction X. The track 143 forms a closed track around the central axis of the turret shaft 130, and the track 143 can be a ring structure so that the connecting component 141 will circulate along the track 143 as it rotates with the turret shaft 130.

[0088] In this embodiment of the disclosure, the track 143 may include two or more track segments. It is understood that when the track segment through which the connector 141 passes is close to the test turntable 110, the connector 141 drives the test component 120 closer to the test turntable 110, so that the test component 120 can contact the battery cell 700 on the test turntable 110 for testing; when the track segment through which the connector 141 passes is far from the test turntable 110, the connector 141 drives the test component 120 away from the test turntable 110, and the test component 120 separates from the battery cell 700 on the test turntable 110, so that the battery cell 700 can enter and exit the test turntable 110.

[0089] The technical solution of this embodiment involves setting a track component 142 with a track 143. During the rotation of the connecting component 141 following the turret shaft 130, the connecting component 141 also moves along the track 143. Since the track 143 includes at least two track segments with different distances from the test turntable 110, the connecting component 141 rises or falls in the corresponding track segments, thereby driving the test component 120 to rise and fall. Since the rise and fall of the test component 120 is related to the rotation of the test turntable 110, it has high matching accuracy.

[0090] To facilitate the lifting and lowering of the test assembly 120 along the track 143, referring to Figures 4, 5 and 6, in some possible embodiments of this disclosure, at least two track segments include a separation segment 1431, a test segment 1432, and a connecting segment 1433 connecting the separation segment 1431 and the test segment 1432. Along the axial direction of the turret shaft 130, the first distance H1 between the separation segment 1431 and the test turntable 110 is greater than the second distance H2 between the test segment 1432 and the test turntable. When the connecting member 141 moves to the test segment 1432, the test assembly 120 contacts the battery cell 700 at the corresponding position.

[0091] In this embodiment, the first distance H1 between the separation segment 1431 and the test turntable 110 is greater than the second distance H2 between the test segment 1432 and the test turntable 110. It is understood that when the connector 141 moves to the separation segment 1431, the connector 141 causes the test assembly 120 to move relatively away from the test turntable 110, thereby separating the test assembly 120 from the corresponding battery cell 700; when the connector 141 moves to the test segment 1432, the connector 141 causes the test assembly 120 to move relatively closer to the test turntable 110, thereby bringing the test assembly 120 into contact with the corresponding battery cell 700.

[0092] In this embodiment of the disclosure, the separation section 1431 and the test section 1432 may be parallel to the radial plane of the turret shaft 130. In one example, the separation section 1431 corresponds to the feed side and the discharge side of the test turret 100, and the test section 1432 corresponds to the movement trajectory of the cup 600 between the feed side and the discharge side.

[0093] In this embodiment, the connecting segment 1433 is used to connect the separating segment 1431 and the test segment 1432. It is understood that at least two connecting segments 1433 are provided so that the test segment 1432 and the separating segment 1431 are connected end-to-end. The extension direction of the connecting segment 1433 is set at an angle to a preset direction X, that is, one end of the connecting segment 1433 is away from the test turntable 110 and connects to the separating segment 1431, while the other end is close to the test turntable 110 and connects to the test segment 1432. Furthermore, the connection position between the connecting segment 1433 and the test segment 1432 / separating segment 1431 can also be provided with an arc-shaped chamfer. The provision of the connecting segment 1433 and the arc-shaped chamfer both contribute to the smooth movement of the connecting member 141 along the track 143.

[0094] The technical solution of this disclosure embodiment, by setting a separation section 1431 and a test section 1432, allows the connector 141 to move to the separation section 1431 to lift the test assembly 120, so as to facilitate the transport of the battery cell 700 in and out; the connector 141 can move to the test section 1432 to drive the test assembly 120 to contact the battery cell 700, so as to facilitate the testing of the test assembly 120.

[0095] To facilitate the testing of the battery cell 700 by the test assembly 120, referring to Figures 5 and 6, in some possible embodiments of this disclosure, the test segment 1432 has a first dimension L1 along the circumference of the track member 142, and the separation segment 1431 has a second dimension L2 along the circumference of the track member 142, wherein the first dimension L1 is greater than the second dimension L2.

[0096] In this embodiment, the dimension of track 143 along the circumference of track member 142 can also be understood as the dimension of the connecting member 141 along the movement path of track 143. The first dimension L1 of test segment 1432 along the circumference of track member 142 is greater than the second dimension L2 of separation segment 1431 along the circumference of track member 142. During the process of connecting member 141 completing a uniform speed cycle along track 143, the time that connecting member 141 is in test segment 1432 is greater than the time that it is in separation segment 1431. That is, the test component 120 contacts the corresponding battery cell 700 for a longer time, which provides sufficient time to complete the test and allows for more types of tests.

[0097] In the technical solution of this disclosure embodiment, since the first size L1 of the test section 1432 is larger than the second size L2 of the separation section 1431, the test component 120 can have more time to contact the battery cell 700, so as to facilitate testing.

[0098] To facilitate the movement of the connecting member 141 along the track 143, referring to Figures 3 and 4, in some possible embodiments of this disclosure, the lifting assembly 140 further includes a rotating member 144, the track 143 is a track groove opened on the outer periphery of the track member 142, the rotating member 144 is rotatably disposed in the track groove, and the connecting member 141 is connected to the rotating member 144.

[0099] In this embodiment, the rotating member 144 can be an elastic rotating member 144, which has good adaptability and smooth movement; or the rotating member 144 can be a rigid rotating member 144, which has good support stability. The connecting member 141 can be arranged parallel to a preset direction X. The upper end of the connecting member 141 away from the test turntable 110 is rotatably connected to the rotating member 144. The rotating member 144 is placed in the track groove, and the lower end of the connecting member 141 near the test assembly 120 is connected to the test assembly 120.

[0100] In this embodiment, the rotating component 144 can be a roller, a ball bearing, etc., and this embodiment is not limited thereto. The connecting component 141 and the rotating component 144 can be fixedly connected or rotatably connected, and the same connecting component 141 can connect one or more rotating components 144. It should be noted that the rotating component 144 can also be omitted, that is, the connecting component 141 can slide directly in the track groove.

[0101] In this embodiment, the track groove can be unilaterally limited, meaning that the rotating member 144 contacts the inner wall of the track groove on one side along a preset direction X and is supported by the corresponding inner wall of the track groove, while the other side does not contact the inner wall of the track groove. The track groove can also be unilaterally limited, meaning that the rotating member 144 contacts the opposite inner walls of the track groove on both sides along a preset direction.

[0102] In addition, the opening of the track groove can be provided with a flange to make the size of the opening smaller, so as to confine the rotating part 144 within the track groove and reduce the possibility of the rotating part 144 coming out of the track groove.

[0103] In the technical solution of this embodiment, the track 143 is in the form of a track groove, which can limit the rotation member 144 therein to improve the guiding accuracy. The rotation member 144 can reduce friction so that the connecting member 141 can move smoothly along the track 143.

[0104] To facilitate the sliding connection of the connector 141, referring to Figures 1, 7 and 8, in some possible embodiments of this disclosure, the test turret 100 further includes a support member 150. The support member 150 is disposed between the track member 142 and the test turntable 110 and is fixedly disposed relative to the turret shaft 130. The connector 141 is slidably connected to the outer periphery of the support member 150.

[0105] In this embodiment, the relative fixation of the support member 150 and the turret shaft 130 is specifically that the two are directly or indirectly fixedly connected and can be relatively stationary, that is, the support member 150 can move synchronously with the turret shaft 130.

[0106] In this embodiment, the support member 150 can be sleeved on the outer periphery of the turret shaft 130, and the support member 150 and the turret shaft 130 are fixed together by means of threaded connection, snap-fit, fastener connection, etc. For example, the support member 150 is locked to the turret shaft 130 by multiple fasteners, which are evenly arranged around the turret shaft 130 to provide a stable connection and facilitate disassembly and maintenance.

[0107] In this embodiment of the disclosure, the radial dimension of the support member 150 can be greater than, equal to, or less than the radial dimension of the test turntable 110; the radial dimension of the support member 150 can be greater than, equal to, or less than the radial dimension of the track member 142. For example, the radial dimension of the track member 142 is less than the radial dimension of the test turntable 110, and the radial dimension of the support member 150 is less than the radial dimension of the track member 142, so that the connector 141 can connect the track member 142 and the support member 150 respectively.

[0108] In this embodiment of the present disclosure, a groove may be provided on the support member 150, and the connector 141 is slidably connected in the groove. Alternatively, a guide member and a sliding member assembly may be provided between the support member 150 and the connector 141, and the support member 150 provides support and limit for the connector 141 to improve the movement accuracy of the test component 120 along the preset direction X.

[0109] The technical solution of this disclosure embodiment provides a support member 150 for sliding connection of the connector 141. Since the support member 150 has a larger radial dimension relative to the turret shaft 130, it can provide better support for the connector 141 and also provide a larger movement space for the test assembly 120.

[0110] To balance weight reduction and support stability, referring to Figures 7, 8 and 9, in some possible embodiments of this disclosure, the support member 150 includes a support plate 151 and a support sleeve 152. The support plate 151 is fixed to the turret shaft 130, and the support sleeve 152 is sleeved on the outer periphery of the support plate 151. The connector 141 is movably connected to the support sleeve 152, and along the axial direction of the turret shaft 130, the size of the support sleeve 152 is larger than the size of the support plate 151.

[0111] In this embodiment of the disclosure, the movable connection between the connector 141 and the support sleeve 152 means that the two can move relative to each other, and the connection between the two can be a sliding connection, a flexible connection, a transmission connection, etc.

[0112] In this embodiment, the support plate 151 and the support sleeve 152 can be connected by snap-fitting, bonding, welding, or other methods. For example, the support plate 151 and the support sleeve 152 are integrally formed. The dimension of the support sleeve 152 along a predetermined direction X is larger than the dimension of the support plate 151 along the predetermined direction X, so that the axial cross-section of the support member 150 has an "H" shape, which provides both high structural strength and a large support surface.

[0113] In this embodiment, the support plate 151 is fixed to the turret shaft 130 by fasteners, and the outer periphery of the support sleeve 152 is used to support the connector 141 so that when the connector 141 corresponds to the movement trajectory of the cup 600, the connector 141 can be set parallel to the preset direction X and stably supported by the support sleeve 152.

[0114] In the technical solution of this embodiment, the support member 150 is configured as two parts: a support plate 151 and a support sleeve 152. The support sleeve 152 can provide a larger support size to facilitate the stable connection of the connector 141, and the axial dimension of the support plate 151 is small, which is also conducive to weight reduction.

[0115] To stably guide the movement of the connector 141, referring to Figures 3, 4 and 7, in some possible embodiments of this disclosure, the test turret 100 further includes a guide assembly 160, which includes a guide member 161 and a slider 162. The guide member 161 is connected to the outer periphery of the support member 150, and the slider 162 is connected to the guide member 161 and moves along the guide member 161. The connector 141 is connected to the slider 162, and the support sleeve 152 extends to both ends of the guide member 161 along the movement direction of the slider 162.

[0116] In this embodiment, the connection between the slider 162 and the guide 161 can be such that the guide 161 has a groove, and a portion of the slider 162 extends into the groove and slides; or, the slider 162 is sleeved on the outside of the guide 161 and slides. For example, the guide 161 has grooves on both sides of the support 150's periphery, the grooves extending in a predetermined direction X. The slider 162 is sleeved on the outside of the guide 161, and the slider 162 has two sliding portions that extend into the two grooves respectively, to achieve a sliding connection between the two, resulting in better guiding accuracy and connection stability.

[0117] In this embodiment of the present disclosure, the slider 162 moves along the guide 161, and the extension direction of the guide 161 can be set parallel to the preset direction X, and the slider 162 slides relative to the guide 161 parallel to the preset direction X.

[0118] In this embodiment, the guide member 161 can be fixed to the outer periphery of the support sleeve 152 by means of bonding, snap-fitting, welding, fastener connection, etc., and the dimensions of the guide member 161 and the support sleeve 152 along the preset direction X are similar or equal, so that the two have sufficient connection area, and the support sleeve 152 provides stable support for the guide member 161. In one example, the support sleeve 152 has a slot 153, and the guide member 161 is snapped into the slot 153.

[0119] The technical solution of this embodiment is provided by setting a guide component 160. The slide rail of the guide component 160 is fixed to the support sleeve 152, and the support sleeve 152 extends to both ends of the guide member 161, which can provide stable support for the guide member 161. The connecting member 141 is slidably connected to the guide member 161 through the sliding member 162. Under the guidance of the guide component 160, it can move smoothly in the preset direction X.

[0120] To facilitate the disassembly and maintenance of the test turret 100, referring to Figures 7, 8 and 9, in some possible embodiments of this disclosure, the test turret 100 further includes a locking assembly 170, which is connected to the sliding member 162. The locking assembly 170 includes at least two relatively movable locking parts 171 for locking and fixing the connecting member 141.

[0121] In this embodiment of the disclosure, the locking component 170 can be fixedly connected to the slider 162 or movably connected to the slider 162. For example, the locking component 170 is fixedly connected to the slider 162 by a plurality of fasteners, and the plurality of fasteners are symmetrically distributed on both sides of the locking component 170 to provide a stable connection.

[0122] In this embodiment of the disclosure, the locking assembly 170 may include two or more locking parts 171, forming a clamping space 172 between the locking parts 171. Different locking parts 171 may be independently arranged or connected to each other. In one example, two locking parts 171 are slidably connected to the slider 162 respectively. In another example, two locking parts 171 are connected, and the locking parts 171 are made of elastic material to allow relative movement. A cylindrical clamping space 172 is formed between the two locking parts 171 to adapt to the connector 141, and the connector 141 is clamped in the clamping space 172.

[0123] Based on this, the two locking parts 171 can be fixed together by snap-fit ​​or fastener connection so that the connector 141 can be snap-fitted and locked. For example, each of the two locking parts 171 has a connecting hole at the ends that are far apart from each other. When the locking parts 171 are close to each other and the connector 141 is snapped together, the fastener passes through the connecting hole of the two locking parts 171 to fix the two locking parts 171 relative to each other.

[0124] The technical solution of this embodiment of the disclosure provides a locking component 170, which locks and fixes the connector 141 by locking part 171, making it convenient to disassemble and assemble the connector 141 relative to the guide component 160, so as to facilitate the maintenance of the test component 120, test turntable 110, etc.

[0125] To improve testing efficiency, referring to Figures 2 and 3, in some possible embodiments of this disclosure, the test turntable 110 includes a receiving groove 111 for accommodating a cup 600, there are at least two receiving grooves 111, and at least some of the receiving grooves 111 are correspondingly provided with test components 120.

[0126] In this embodiment, the test turntable 110 may include a turntable portion and a retaining portion. The turntable portion rotates with the turret shaft 130. The retaining portion is disposed on the outer periphery of the turntable portion and is fixed relative to the base of the test device, that is, the retaining portion does not rotate with the turret shaft 130. The receiving groove 111 is opened on the outer periphery of the turntable portion and is a semi-circular or semi-elliptical opening. The cup 600 enters the receiving groove 111 and is surrounded by the retaining portion and the inner wall of the receiving groove 111 so as to move with the rotation of the turntable portion.

[0127] In this embodiment of the present disclosure, the enclosure portion is provided with an opening on the feed side or the discharge side of the test turret 100, so that the cup 600 can enter the test turret 110 from the opening on the feed side and leave the test turret 110 from the opening on the discharge side.

[0128] In this embodiment of the disclosure, multiple receiving slots 111 can be distributed at equal intervals along the circumference of the test turntable 110, which facilitates the uniformity of force on the test turret 100 and the uniform speed transfer of the cup 600.

[0129] In this embodiment of the present disclosure, the receiving slots 111 on the turntable can be used entirely to accommodate the cup 600, or partially to accommodate the cup 600, depending on the design requirements. The receiving slots 111 used to accommodate the cup 600 are correspondingly provided with test components 120, which can test the battery cells 700 in the receiving slots 111.

[0130] To improve testing efficiency, in some embodiments, each of the receiving slots 111 for accommodating the cup 600 is provided with a corresponding test component 120. It is understood that when there are at least two test components 120, at least two connectors 141 are also provided, each corresponding to a test component 120.

[0131] The technical solution of this disclosure embodiment, by setting at least two receiving slots 111, enables the test turntable 110 to simultaneously transfer multiple battery cells 700, and at least two test components 120, can test the multiple battery cells 700 on the test turntable 110, thereby improving the testing efficiency.

[0132] To facilitate the electrical connection of the test component 120, referring to Figures 1 and 12, in some possible embodiments of this disclosure, the test device further includes a power transmission mechanism 400. The power transmission mechanism 400 includes a first ring body 410, a second ring body 420, and a conductive wire harness. The first ring body 410 and the second ring body 420 are rotatable relative to each other and electrically connected. The second ring body 420 is fixed relative to the test turntable 110. The conductive wire harness is connected between the second ring body 420 and the test component 120.

[0133] In this embodiment, the second ring 420 is fixed relative to the test turntable 110, specifically, the axes of the two overlap. The second ring 420 is connected to the test turntable 110 by means of snap-fit, bonding, welding, interference fit, etc., and the second ring 420 can move synchronously with the test turntable 110.

[0134] In this embodiment, the power transmission mechanism 400 can be an electric slip ring, and includes a first ring body 410 and a second ring body 420. The first ring body 410 is fixed relative to the base of the testing device, and is connected to the power supply equipment, the testing host, etc. via a wire harness. The second ring body 420 is sleeved on the outer periphery of the first ring body 410, and the first ring body 410 rotates coaxially with the testing turntable 110. The testing assembly 120 is connected to the second ring body 420 via a conductive wire harness, and is thus electrically connected to the power supply equipment, the testing host, etc.

[0135] In this embodiment, the first ring 410 and the second ring 420 can be connected by a single electrical path or multiple electrical paths. For example, the first ring 410 includes at least two conductive grooves that are insulated from each other along a predetermined direction X, and the second ring 420 includes at least two conductive portions that are insulated from each other along a predetermined direction X. The at least two conductive portions slide one-to-one within the at least two conductive grooves to form at least two electrical connections, with each conductive portion connected to a conductive wire harness. It is understood that the number of electrical connection paths in the power transmission mechanism 400 corresponds to the number of test components 120.

[0136] In this embodiment of the disclosure, the power transmission mechanism 400 can be disposed between the support member 150 and the test turntable 110, or it can be disposed between the support member 150 and the track member 142. In one example, the test turntable 110 is disposed on the side of the track member 142 away from the test turntable 110.

[0137] In some possible embodiments, the power transmission component may be omitted, and a wireless connection may be used to establish an electrical connection between the test probe 121 and the test host and power supply equipment. The wireless connection may be electromagnetic power transmission, Bluetooth, star flash, wireless network, etc.

[0138] The technical solution of this disclosure embodiment provides a power transmission mechanism 400, which includes a first ring 410 and a second ring 420 that are electrically connected. The second ring 420 is connected to the test component 120 through a conductive wire harness and can rotate synchronously to avoid the guide wire harness from getting tangled during rotation, thus optimizing the electrical connection method of the test component 120.

[0139] To facilitate the connection of the test probe 121, referring to Figures 4, 10 and 11, in some possible embodiments of this disclosure, the test assembly 120 includes a test probe 121 and an adapter 122. The adapter 122 has a defined extension direction, and the dimension of the adapter 122 along the extension direction is larger than the dimension of the adapter 122 along the other directions. The two ends of the adapter 122 along its extension direction are respectively connected to the test probe 121 and the test turntable 110.

[0140] In this embodiment of the disclosure, the extension direction of the adapter 122 is its maximum size. For example, if the adapter 122 is a rod-shaped structure, the extension direction is its axial direction; or if the adapter 122 is a plate-shaped structure or a block-shaped structure, the extension direction is its length direction.

[0141] In this embodiment, the adapter 122 can be a rectangular plate structure. One end of the adapter 122 is connected to the lifting assembly 140. For example, one end of the adapter 122 along its length is fixedly connected to the lower end of the connector 141, and the other end of the adapter 122 along its length is used to install the test probe 121. The adapter 122 and the connector 141 can be bonded, welded, snapped, etc. For example, the adapter 122 has an assembly hole 123, and the end of the connector 141 extends into the assembly hole 123 to achieve connection.

[0142] In this embodiment, the test probe 121 can be fixed to the adapter 122 by means of snap-fit, bonding, welding, threaded connection, fastener connection, etc. For example, the adapter 122 is provided with a fixing hole 124, which is a through hole. The test probe 121 passes through the fixing hole 124, which can provide stable support and limit for the test probe 121, and also facilitate the connection of the test probe 121 to the power transmission mechanism 400 through the conductive wire harness.

[0143] In addition, the portion of the adapter 122 that connects to the test probe 121 is provided with a protrusion 125, thereby increasing the radial dimension of the fixing hole 124, increasing the connection area between the test probe 121 and the adapter 122, and improving the stability of the test probe 121.

[0144] The technical solution of this disclosure embodiment, by setting up an adapter 122, connects the test probe 121 to one end of the adapter 122, which is less likely to interfere with other components of the test turret 100 and facilitates the connection of the test probe 121.

[0145] To make the structure of the test turret 100 more compact, referring to FIG12, in some possible embodiments of this disclosure, the test turntable 110 is provided with a diametrical direction toward the adapter 122, and the extension direction of the adapter 122 is set at an angle to the corresponding diametrical direction.

[0146] In this embodiment of the disclosure, the test turntable 110 can be a disc structure. The test turntable 110 has multiple diameter directions perpendicular to its axial direction. It is understood that the multiple diameter directions are different. When projected along the axial direction of the test turntable 110, some diameter directions pass through the projection of the adapter 122. The extension direction of the adapter 122 is set at an acute angle, a right angle or an obtuse angle with the corresponding diameter direction. In other words, the extension direction of the adapter 122 is not parallel to the corresponding diameter direction.

[0147] In this embodiment of the present disclosure, the test turntable 110 has an upper surface close to the test assembly 120, and the extension direction of the adapter 122 can be parallel to the upper surface of the test turntable 110, or it can be set at an acute or obtuse angle with the upper surface.

[0148] In this embodiment, the adapter 122 is parallel to the test turntable 110, meaning that the length and width directions of the adapter 122 are parallel to the radial plane of the test turntable 110, and the thickness direction of the adapter 122 is set along a preset direction X. The length direction of the adapter 122 can be set along the radial or circumferential direction of the test turntable 110, or along other directions within the radial plane of the test turntable. Specifically, when the length direction of the adapter 122 is along the circumferential direction of the test turntable 110, multiple adapters 122 are connected end-to-end along the circumferential direction of the test turntable 110, and the extended lines of the long sides of the adapters 122 form the tangent or secant of the circumcircle of the test turntable 110.

[0149] In this embodiment, the test probe 121 can be arranged along a preset direction X, perpendicular to the preset direction X, or inclined. Furthermore, there can be one, two, or more test probes 121. Two test probes 121 can be arranged radially or circumferentially along the test turntable 110. Two or more test probes 121 can be arranged in a triangular, circular, or square shape. For example, two test probes 121 are spaced apart along the length of the adapter 122.

[0150] In the technical solution of this embodiment, the adapter 122 is parallel to the test turntable 110. On the one hand, it facilitates the connection between the test probe 121 and the adapter 122. On the other hand, the extension direction of the adapter 122 is set at an angle to the corresponding diameter direction, which can make the size of the connector 141 smaller, thereby making the structure of the test turret 100 more compact.

[0151] Referring to Figure 1, in some possible embodiments of this disclosure, the testing apparatus further includes a feed turntable 200 and a discharge turntable 300. The feed turntable 200 is disposed on the feed side of the testing turret 100 and is used to transport the cup 600 into the testing turntable 110; the discharge turntable 300 is disposed on the discharge side of the testing turret 100 and is used to transport the cup 600 out of the testing turntable 110. The feed turntable 200 and the discharge turntable 300 may adopt the same or different structural forms as the testing turntable 110.

[0152] In this embodiment, the feeding turntable 200 receives a cup 600 containing battery cells 700 from an upstream station such as an assembly station, and transports the cup 600 to a testing turntable 110 by rotation. The testing turntable 110 rotates the cup 600 from the feeding side to the discharging side, where it is received by the discharging turntable 300 and transferred to a downstream station such as a packaging station. The cup 600 provides protection for the battery cells 700 contained within it.

[0153] To improve the coordination between the test turntable 110, the feed turntable 200, and the discharge turntable 300, referring to FIG13, in some possible embodiments of this disclosure, the testing device further includes a synchronization mechanism 500 and a drive mechanism. The test turntable 110, the feed turntable 200, and the discharge turntable 300 are connected through the synchronization mechanism 500, and the drive mechanism is connected to the synchronization mechanism 500 to drive the test turntable 110, the feed turntable 200, and the discharge turntable 300 to move synchronously.

[0154] In this embodiment of the disclosure, the synchronization mechanism 500 can be one or more combinations of gear mechanism, gear and rack mechanism, cam mechanism, ratchet mechanism, Geneva mechanism, worm gear mechanism, ball screw mechanism, belt drive mechanism, chain drive mechanism, and linkage mechanism.

[0155] In this embodiment of the disclosure, the drive mechanism can be a drive component that drives the output shaft to rotate, such as a motor or a rotary cylinder, or a drive component that drives the output shaft to move linearly, such as a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod. The motor can be a servo motor, a stepper motor, or the like. For example, the drive mechanism is a motor.

[0156] In this embodiment, the feed turntable 200 corresponds to the feed side of the test turntable 110, and the discharge turntable 300 corresponds to the discharge side of the test turntable 110. The feed side and discharge side of the test turntable 110 can be symmetrically distributed, or the feed side and discharge side can be separated by an acute or obtuse angle. The movement path of the cup 600 is set along the superior arc between the feed side and the discharge side, so that the test component 120 has more contact time with the battery cell 700.

[0157] The technical solution of this disclosure embodiment can drive the test turntable 110, the feeding turntable 200 and the discharging turntable 300 to move synchronously through the synchronization mechanism 500, so as to improve the coordination of the three and facilitate the transfer of the cup 600 among the three. Moreover, the synchronization mechanism 500 only requires one set of drive mechanism, which can also simplify the structure.

[0158] A second aspect of this disclosure provides a battery withstand voltage testing system. Referring to FIG14, the battery withstand voltage testing system includes a production equipment 800, a transport equipment 900, and a testing device. The production equipment 800 is used to produce battery cells 700; the testing device is used to perform withstand voltage tests on the battery cells 700; and the transport equipment 900 is disposed between the production equipment 800 and the testing device for transporting the battery cells 700.

[0159] In this embodiment of the disclosure, the production equipment 800 is used to produce battery cells 700 or to assemble battery cells 700 into battery devices. For example, the production equipment 800 may be an assembly equipment that assembles battery cells 700 into a housing, or a welding equipment that connects multiple battery cells 700 in the housing. Depending on the process sequence, the production equipment 800 may have various possible forms.

[0160] In this embodiment of the disclosure, the transfer device can take many possible forms. For example, the transfer device is a conveyor belt, which has a simple structure and high transportation efficiency. Another example is an arm robot, which can perform more complex operations.

[0161] In the technical solution of this embodiment, the battery withstand voltage testing system includes the aforementioned testing device. The testing component 120 is connected to the testing turntable 110 and rotates synchronously with the testing turntable 110. That is, the testing component 120 moves synchronously with the cup 600 and the battery cell 700 on the testing turntable 110. The testing component 120 and the battery cell 700 can remain relatively stationary. While the testing turntable 110 is transferring the battery, the testing component 120 can test the battery cell 700. This testing process does not require pausing the cup 600 and the battery cell 700, ensuring the continuity of the battery cell 700 transfer process. Moreover, the transfer and testing are carried out simultaneously, which can save testing time and optimize the production cycle.

[0162] Referring to Figures 1, 2, and 3, in one possible embodiment of this disclosure, the testing apparatus includes a testing turret 100. The testing turret 100 includes a turret shaft 130 and a testing turntable 110 connected to each other. A feeding turntable 200 is provided on the feeding side of the testing turntable 110, and a discharging turntable 300 is provided on the discharging side of the testing turntable 110. The cup 600 moves sequentially along the feeding turntable 200, the testing turntable 110, and the discharging turntable 300. The testing turret 100 includes a turret shaft 130, the lower end of which is connected to a synchronization mechanism 500. The synchronization mechanism 500 is connected to the feeding turntable 200, the discharging turntable 300, and a drive mechanism, respectively, so that the drive mechanism drives the feeding turntable 200, the testing turntable 110, and the discharging turntable 300 to move synchronously, that is, to move at the same linear velocity.

[0163] The test turntable 110 has a support member 150 on its upper side. A guide component 160 is connected to the outer periphery of the support member 150. The guide component 160 includes a guide member 161 and a sliding member 162. The sliding member 162 is connected to a locking component 170, which clamps and fixes a connector 141. The connector 141 is cylindrical and positioned along a preset direction X. The lower end of the connector 141 is connected to a test probe 121 via an adapter 122, and the upper end of the connector 141 is connected to the track 143 of the track component 142 via a rotating member 144. During the rotation of the test turntable 110, the support member 150 drives the connector 141 to rotate synchronously, thereby causing the test component 120 and the test turntable 110 to rotate synchronously. The test component 120 remains stationary relative to the battery cell 700 on the test turntable 110, facilitating the testing of the battery cell 700 by the test component 120.

[0164] The track 143 includes a test section 1432 and a separation section 1431. The first distance H1 between the separation section 1431 and the test turntable 110 is greater than the second distance H2 between the test section 1432 and the test turntable 110. When the connector 141 moves to the separation section 1431, the connector 141 drives the test component 120 to move away from the test turntable 110, so that the test component 120 is separated from the corresponding battery cell 700, which facilitates the entry and exit of the battery cell 700 from the test turntable 110. When the connector 141 moves to the test section 1432, the connector 141 drives the test component 120 to move closer to the test turntable 110, so that the test component 120 contacts the corresponding battery cell 700 for testing.

[0165] In addition, a power transmission component is provided, which includes a first ring 410 and a second ring 420 that are electrically connected. The second ring 420 is connected to the test probe 121 of the test component 120 through a conductive wire harness. The second ring 420 rotates with the turret shaft 130 to maintain the electrical connection of the test component 120 so as to facilitate the transmission of signals and electrical energy.
