Description

Technical Field

[0001] This application relates to the technical field of battery testing, and particularly relates to a testing device and a battery withstand voltage testing system. Background Art

[0002] During the battery production process, it is usually necessary to detect battery cells, for example, to perform a withstand voltage test through electrical equipment to determine whether the insulation and withstand voltage of the battery cells meet the requirements. In the related art, the testing efficiency is low, which affects the production rhythm. Summary of the Invention

[0003] To solve the above technical problems, the purpose of this application is to provide a testing device and a battery withstand voltage testing system.

[0004] The first aspect of this application provides a testing device, which includes a testing turret. The testing turret is provided with a feeding side and a discharging side. The testing turret includes a testing turntable and a testing component. The testing turntable is used to transfer a carrier cup between the feeding side and the discharging side, and the carrier cup is used to carry a battery cell; 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 moving direction; the testing component is used to test the battery cells in the testing turntable.

[0005] In the technical solution provided by the embodiments of this application, the testing turret includes a testing turntable and a testing component. The testing turntable can drive the carrier cup to move from the feeding side to the discharging side to realize the transfer of the carrier cup and the corresponding battery cell. 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 carrier cup and the battery cell on the testing turntable. The testing component and the battery cell can remain relatively stationary. While the testing turntable transfers the battery, the testing component can test the battery cell. This testing process does not need to pause the carrier cup and the battery cell, ensuring the continuity of the battery cell transfer process, and the transfer and testing are carried out synchronously, saving time, thereby accelerating the production rhythm of the battery cell and improving the production efficiency. Compared with the solution in the related art where the battery cell needs to be paused for testing, the testing component of this application moves synchronously with the testing turntable and performs testing while the battery cell is being transferred, saving testing time, accelerating the production rhythm, and improving the production efficiency.

[0006] In some embodiments of this application, the testing turret further includes a turret shaft and a lifting component. The lifting component and the testing turntable are coaxially connected to the turret shaft, and the testing component is connected to the lifting component. The lifting component is used to drive the testing component to approach or move away from the testing turntable.

[0007] Here, by setting up the 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 drives the test component away from the battery cell, reducing the possibility of collision between the test component and the battery cell; in the case of testing, the lifting component drives the test component closer to the battery cell so that the test component can test the battery cell, which not only facilitates the test but also protects the test component and the battery cell.

[0008] In some embodiments of the present application, the lifting component includes a connecting piece, the connecting piece is respectively connected to the test component and the turret shaft, and the connecting piece is arranged to rotate relative to the turret shaft; alternatively, the connecting piece is arranged to translate relative to the turret shaft.

[0009] Here, by setting up the connecting piece, the connecting piece is arranged to rotate relative to the turret shaft to form a lever structure, which can not only drive the test component to lift along the axial direction of the turret shaft but also drive the test component to move along the radial direction of the turret shaft; the connecting piece can also translate relative to the turret shaft to drive the test component to lift, and the structure is simpler.

[0010] In some embodiments of the present application, the lifting component further includes a track member, the track member is coaxially connected to the turret shaft and arranged to rotate relative to it, and a circumferentially surrounding track is provided on the track member; the track includes at least two track segments, and along the axial direction of the turret shaft, the distances between at least two track segments and the test turntable are different. The connecting piece follows the rotation of the turret shaft and moves along the track to drive the test component closer to or farther away from the test turntable.

[0011] Here, by setting up the track member, the track member is provided with a track. During the process of the connecting piece following the rotation of the turret shaft, the connecting piece will also move along the track. Since the track includes at least two track segments with different distances from the test turntable, the connecting piece rises or falls on the corresponding track segments, thereby driving the test component to achieve lifting. Since the lifting of the test component is associated with the rotation of the test turntable, it has a high matching accuracy.

[0012] In some embodiments of the present application, at least two track segments include a separation segment, a test segment, and a connection segment connecting the separation segment and the test segment. Along the axial direction of the turret shaft, the first distance between the separation segment and the test turntable is greater than the second distance between the test segment and the test turntable. When the connecting piece moves to the test segment, the test component contacts the battery cell at the corresponding position.

[0013] Here, by setting up the separation segment and the test segment, when the connecting piece moves to the separation segment, the test component can be lifted to facilitate the loading and unloading of the battery cell; when the connecting piece moves to the test segment, it can drive the test component to contact the battery cell to facilitate the test component to conduct the test.

[0014] In some embodiments of the present application, the test section has a first dimension along the circumferential direction of the rail member, and the separation section has a second dimension along the circumferential direction of the rail member, and the first dimension is greater than the second dimension.

[0015] Here, since the first dimension of the test section is greater than the second dimension of the separation section, the test assembly can have more time to contact the battery cell to facilitate the test.

[0016] In some embodiments of the present application, the lifting assembly further includes a rotating member, the rail is a rail groove formed on the outer peripheral side of the rail member, the rotating member is rotatably arranged in the rail groove, and the connecting member is connected to the rotating member.

[0017] Here, the rail is in the form of a rail groove, which can limit the rotating member therein to improve the guiding accuracy, and the setting of the rotating member can reduce the friction so that the connecting member can move smoothly along the rail.

[0018] In some embodiments of the present application, the test turret further includes a support member, the support member is arranged between the rail member and the test turntable and is fixedly arranged relative to the turret shaft, and the connecting member is movably connected to the outer peripheral side of the support member.

[0019] Here, by providing the support member, the support member is used for the sliding connection of the connecting member. Since the support member has a relatively large radial dimension relative to the turret shaft, it can provide good support for the connecting member and also provide a large movement space for the test assembly.

[0020] In some embodiments of the present application, the support member includes a support disk and a support sleeve, the support disk is fixed to the turret shaft, the support sleeve is sleeved on the outer periphery of the support disk, the connecting member is movably connected to the support sleeve, and along the axis direction of the turret shaft, the dimension of the support sleeve is greater than the dimension of the support disk.

[0021] Here, the support member is provided as two parts, namely a support disk and a support sleeve. The support sleeve can provide a relatively large support dimension to facilitate the stable connection of the connecting member, and the axial dimension of the support disk is small, which is also beneficial for weight reduction.

[0022] In some embodiments of the present application, the test turret further includes a guiding assembly, the guiding assembly includes a guiding member and a sliding member, the guiding member is connected to the outer peripheral side of the support member, the sliding member is connected to the guiding member and moves along the guiding member, the connecting member is connected to the sliding member, and the support sleeve extends to both ends of the guiding member along the movement direction of the sliding member.

[0023] Here, by providing the guiding assembly, the slide rail of the guiding assembly is connected to the support sleeve, and the support sleeve extends to both ends of the guiding member, which can provide stable support for the guiding member. The connecting member is connected to the guiding member through the sliding member and can move smoothly along the preset direction under the guidance of the guiding assembly.

[0024] In some embodiments of the present application, the test turret further includes a locking assembly. The locking assembly is connected to the sliding member and includes at least two relatively movable locking portions for locking and fixing the connecting member.

[0025] Here, by providing the locking assembly, the locking assembly locks and fixes the connecting member through the locking portions, facilitating the disassembly and assembly of the connecting member relative to the guiding assembly, so as to facilitate the maintenance of the test assembly, the test turntable, etc.

[0026] In some embodiments of the present application, the test turntable includes a receiving groove for receiving the receiving cup. There are at least two receiving grooves, and at least part of the receiving grooves are correspondingly provided with test components.

[0027] Here, by providing at least two receiving grooves, 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 test efficiency.

[0028] In some embodiments of the present application, the test device further includes a power transmission mechanism. The power transmission mechanism includes a first ring body, a second ring body, and a 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 relatively fixed to the test turntable, and the wire harness is connected between the second ring body and the test component.

[0029] Here, by providing the power transmission mechanism, the power transmission mechanism includes the first ring body and the second ring body that are electrically connected. The second ring body and the test component are connected by the wire harness and can rotate synchronously to avoid the wire harness being wound during rotation, optimizing the electrical connection method of the test component.

[0030] In some embodiments of the present application, the test component includes a test probe and an adapter. The adapter has a set extension direction. The dimension of the adapter along the extension direction is greater 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.

[0031] Here, by providing the adapter, the test probe is connected to one end of the adapter, and it is not easy to interfere with other components of the test turret, facilitating the connection of the test probe.

[0032] In some embodiments of the present application, the test turntable is set with a diameter direction facing the adapter, and the extension direction of the adapter is set at an angle with the corresponding diameter direction.

[0033] Here, the extension direction of the adapter is set at an angle with the corresponding diameter direction, and the enclosure dimension of multiple adapters can be set smaller, so that the structure of the test turret is more compact.

[0034] The second aspect of the present application provides a battery withstand voltage test system, which includes a production device, a transportation device, and the test device of the first aspect. The production device is used for producing battery cells; the test device is used for performing a withstand voltage test on the battery cells; the transportation device is arranged between the production device and the test device and is used for transporting the battery cells.

[0035] In the technical solution of the embodiment of the present application, the battery withstand voltage test system includes the above-mentioned test device. The test component is connected to the test turntable and moves synchronously with the test turntable. That is, the test component moves synchronously with the cup holder and the battery cell on the test turntable. The test component and the battery cell can maintain relative rest. While the test turntable is transporting the battery, the test component can perform a test on the battery cell. This test process does not require pausing the cup holder and the battery cell, ensuring the coherence of the battery cell transportation process. Moreover, the transportation and the test are carried out synchronously, which can save test time and optimize the production rhythm. Description of the Drawings

[0061] Below, this application is described in detail.

[0062] Batteries are increasingly used in life and industry. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as in aerospace and other fields.

[0063] During the battery production process, it is usually necessary to test the battery cells, such as performing a withstand voltage test with electrical equipment to determine whether the insulation and withstand voltage of the battery cells meet the requirements. Since the battery cells are transmitted on the logistics line, the test takes a certain amount of time, and the moving battery cells are usually stopped and released after the test is completed, which will affect the transmission rhythm of the battery cells and further affect the production efficiency of the production line.

[0064] In response to the above technical problems, an embodiment of the present application provides a testing device, in which a testing assembly is connected to a testing turntable and rotates synchronously with the testing turntable, that is, the testing assembly moves synchronously with the supporting cup and the battery cell on the testing turntable, and the testing assembly and the battery cell can remain relatively still. While the testing turntable transports the battery, the testing assembly can test the battery cell. The testing process does not require pausing the supporting cup and the battery cell, thereby ensuring the continuity of the battery cell transportation process. Moreover, the transportation and testing are carried out simultaneously, which saves time, thereby speeding up the production rhythm of the battery cell and improving production efficiency. The following is a detailed description with reference to the accompanying drawings.

[0065] Reference Figure 1 and Figure 2, the test device according to the embodiment of the present application includes a test turret 100. The test turret 100 is provided with a feeding side and a discharging side. The test turret 100 includes a test turntable 110 and a test assembly 120. The test turntable 110 is used to transfer the carrier cup 600 between the feeding side and the discharging side, and the carrier cup 600 is used to carry the battery cell 700; the test assembly 120 is connected to the test turntable 110 and moves synchronously with the test turntable 110. The test assembly 120 and the test turntable 110 are relatively stationary along the moving direction. The test assembly 120 is used to test the battery cell 700 in the test turntable 110.

[0066] In the embodiment of the present application, the carrier cup 600 moves with the test turntable 110, so as to move from the feeding side of the test turret 100 to the discharging side, and is used to carry the battery cell 700. The inner contour of the carrier cup 600 can be set according to the outer contour of the battery cell 700. For example, it is set to be cylindrical to accommodate cylindrical batteries, or set to be square to accommodate square batteries. The outer contour of the carrier cup 600 can be set to be circular, square, oval, etc. Exemplarily, the outer contour of the carrier cup 600 is set to be circular, which has strong collision resistance and is also convenient for switching to different turntables.

[0067] In the embodiment of the present application, synchronous movement means that the test assembly 120 and the test turntable 110 move at the same speed and in the same direction at the same time. The movement of the test assembly 120 following the test turntable 110 can be a rotational movement around a fixed axis, a reciprocating movement along a single track, or a circular movement along a circular track.

[0068] In the embodiment of the present application, the test assembly 120 and the test turntable 110 are relatively stationary along the moving direction. Specifically, when the test turntable 110 moves along the moving track, the test assembly 120 also moves along the moving track. Their positions and speeds on the moving track correspond to each other, and they are relatively stationary corresponding to the moving track. On this basis, the test assembly 120 can also move in other directions, such as approaching or moving away from the test turntable 110.

[0069] When the test assembly 120 follows the test turntable 110 to make a rotational movement, the test assembly 120 and the test turntable 110 have the same rotation axis (that is, their axes overlap), and move at the same angular velocity to maintain relative static. Exemplarily, the test assembly 120 and the test turntable 110 rotate at the same angular velocity, so that the test assembly 120 can be relatively stationary with respect to the test turntable 110, and further make the test assembly 120 relatively stationary with respect to the battery cell 700 at the corresponding position. Among them, the test assembly 120 and the test turntable 110 can be directly connected or indirectly connected.

[0070] In the technical solution provided by the embodiment of the present application, the test turret 100 includes a test turntable 110 and a test assembly 120. The test turntable 110 can drive the cup holder 600 to move from the feeding side to the discharging side, so as to realize the transfer of the cup holder 600 and the corresponding battery cell 700. The test assembly 120 is connected to the test turntable 110 and moves synchronously with the test turntable 110, that is, the test assembly 120 moves synchronously with the cup holder 600 and the battery cell 700 on the test turntable 110. The test assembly 120 can keep relatively stationary with respect to the battery cell 700. While the test turntable 110 is transferring the battery, the test assembly 120 can test the battery cell 700. This test process does not need to pause the cup holder 600 and the battery cell 700, ensuring the coherence of the transfer process of the battery cell 700, and the transfer and the test are carried out synchronously, saving time, thus accelerating the production rhythm of the battery cell 700 and improving the production efficiency.

[0071] Compared with the solution in the related art where the battery cell 700 needs to be paused for testing, the test assembly 120 of the present application moves synchronously with the test turntable 110, and tests while the battery cell 700 is being transferred, saving the test time, accelerating the production rhythm, and improving the production efficiency.

[0072] To protect the test assembly 120 and the battery cell 700, referring to Figure 3 and Figure 4 in some possible embodiments of the present application, 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 drive the test assembly 120 to approach or move away from the test turntable 110.

[0073] In the embodiment of the present application, the turret shaft 130 is used to carry the test turntable 110, the lifting assembly 140, the test assembly 120, etc. It can be understood that the test turntable 110 and the lifting assembly 140 rotate synchronously through the turret shaft 130. Exemplarily, the test turntable 110 is sleeved and fixedly connected to the outer peripheral side 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, and then drives the test assembly 120 connected to the lifting assembly 140 to rotate.

[0074] In the embodiment of the present application, the connection between the lifting assembly 140 and the turret shaft 130 may be a fixed connection or a movable connection, such as a sliding connection, a hinge, etc. The lifting assembly 140 may be an active type, that is, the lifting assembly 140 includes a driving member, and the driving member 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.

[0075] In the embodiment of the present application, the axis of the turret shaft 130 is set parallel to the preset direction X. The movement of the test component 120 approaching or moving away from the test turntable 110 can be along the preset direction X, or can be moved 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 axially and radially along the turret shaft 130.

[0076] The technical solution of the embodiment of the present application is to set up a lifting component 140, and the lifting component 140 can drive the test component 120 to move. In the process of transporting the battery cell 700 into or out of the test turntable 110, the lifting component 140 drives the test component 120 away from the battery cell 700, thereby 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 close to the battery cell 700, so that the test component 120 can test the battery cell 700, which not only facilitates the test but also protects the test component 120 and the battery cell 700.

[0077] In order to facilitate the lifting and lowering movement of the test assembly 120, refer to Figure 3 and Figure 4 In some possible embodiments of the present application, the lifting assembly 140 includes a connecting member 141, which respectively connects the test assembly 120 and the turret shaft 130, and the connecting member 141 and the turret shaft 130 are arranged to rotate relative to each other; or, the connecting member 141 and the turret shaft are arranged to translate relative to each other.

[0078] In the embodiment of the present application, the connecting member 141 and the turret shaft 130 are arranged to rotate relative to each other. Specifically, the two are rotationally connected through a shaft, bearings, etc., or, through a transmission connection such as gears and worm gears, the connecting member 141 and the turret shaft 130 can rotate relative to each other, thereby changing the distance between the end of the connecting member 141 and the test turntable 110.

[0079] In the embodiment of the present application, the part of the connecting member 141 that is rotatably connected to the turret shaft 130 may be the middle part or the end part. In one example, one end of the connecting member 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 part of the connecting member 141 is rotatably connected to the turret shaft 130, and the end of the connecting member 141 close to the test turntable 110 is connected to the test assembly 120.

[0080] In the embodiment of the present application, the connecting member 141 and the turret shaft 130 are arranged to translate relative to each other, specifically, the two are connected by sliding through a slide groove, a guide rail, a linear bearing, etc., or by a transmission connection through a connecting rod mechanism, etc. The connecting member 141 moves along the axis of the turret shaft 130, thereby changing the distance between the end of the connecting member 141 and the test turntable 110.

[0081] In the embodiment of the present application, the connection member 141 can be slidably connected to the turret shaft 130 by direct sliding of the two, for example, the turret shaft 130 is provided with a slide groove, and a portion of the connection member 141 extends into the slide groove and slides. Alternatively, the connection member 141 and the turret shaft 130 are slidably connected by a guide member, a sliding member, etc. It should be noted that the sliding connection can limit the radial movement of the connection member 141 along the turret shaft 130.

[0082] In the embodiment of the present application, the connection between the test component 120 and the connector 141 may be a movable connection, such as a sliding connection, a hinge, a flexible connection, etc.; the connection between the test component 120 and the connector 141 may also be a fixed connection, such as a snap connection, a bonding connection, a welding connection, a riveting connection, a fastener connection, etc. For example, the connector 141 is fixedly connected to the test component 120 at one end close to the test turntable 110 .

[0083] The technical solution of the embodiment of the present application is to set a connecting member 141, and the connecting member 141 is set to rotate relative to the turret shaft 130 to form a lever structure, which can drive the test component 120 to rise and fall 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 connecting member 141 can also be set to translate relative to the turret shaft 130 to drive the test component 120 to rise and fall, and the structure is simpler.

[0084] In order to make the lifting and lowering of the test assembly 120 compatible with the rotation of the test turntable 110, refer to Figure 3 , Figure 4 and Figure 5, in some possible embodiments of the present application, the lifting assembly 140 further includes an orbital member 142. The orbital member 142 is coaxially connected to the turret shaft 130 and is arranged to rotate relative to it. A circumferentially surrounding track 143 is provided on the orbital member 142. The track 143 includes at least two track segments. Along the axial direction of the turret shaft 130, the distances between at least two track segments and the test turntable 110 are different. The connecting member 141 rotates following the turret shaft 130 and moves along the track 143 to drive the test assembly 120 to approach or move away from the test turntable 110.

[0085] In the embodiment of the present application, the orbital member 142 is coaxially arranged with the turret shaft 130, and the two are arranged to rotate relative to each other, that is, the orbital member 142 does not rotate following the turret shaft 130, and the orbital member 142 can be fixed to the base of the test device. Due to the relative movement between the two, during the process of the turret shaft 130 driving the connecting member 141 to rotate, the connecting member 141 will move relative to the orbital member 142.

[0086] In the embodiment of the present application, the orbital member 142 has a disc structure. The track 143 can be arranged on the outer peripheral side of the orbital member 142, or can be arranged on the upper surface or the lower surface of the orbital member 142 along the preset direction X. Among them, the circumferential surrounding of 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 member 141 will move in a cycle along the track 143 during the rotation following the turret shaft 130.

[0087] In the embodiment of the present application, the track 143 can include two or more track segments. It can be understood that when the distance between the track segment passed by the connecting member 141 and the test turntable 110 is relatively small, the connecting member 141 drives the test assembly 120 to approach the test turntable 110, facilitating the test assembly 120 to contact the battery cell 700 on the test turntable 110 for testing; when the distance between the track segment passed by the connecting member 141 and the test turntable 110 is relatively large, the connecting member 141 drives the test assembly 120 to move away from the test turntable 110, and the test assembly 120 is separated from the battery cell 700 on the test turntable 110, facilitating the battery cell 700 to enter and exit the test turntable 110.

[0088] In the technical solution of the embodiment of the present application, by providing the orbital member 142 with the track 143 provided thereon, during the process of the connecting member 141 rotating following the turret shaft 130, the connecting member 141 will also move along the track 143. Since the track 143 includes at least two track segments with different distances from the test turntable 110, the connecting member 141 rises or falls in the corresponding track segments, thereby driving the test assembly 120 to achieve lifting. Since the lifting of the test assembly 120 is associated with the rotation of the test turntable 110, it has a high matching accuracy.

[0089] To facilitate the lifting and lowering of the test component 120 along the track 143, referring to Figure 4 , Figure 5 and Figure 6 , in some possible embodiments of the present application, at least two track segments include a separation segment 1431, a test segment 1432, and a connection 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. When the connecting member 141 moves to the test segment 1432, the test component 120 contacts the battery cell 700 at the corresponding position.

[0090] In the embodiment of the present application, 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 can be understood that when the connecting member 141 moves to the separation segment 1431, the connecting member 141 drives the test component 120 to move relatively away from the test turntable 110, so that the test component 120 is separated from the corresponding battery cell 700; when the connecting member 141 moves to the test segment 1432, the connecting member 141 drives the test component 120 to move relatively closer to the test turntable 110, so that the test component 120 contacts the corresponding battery cell 700.

[0091] In the embodiment of the present application, the separation segment 1431 and the test segment 1432 can be parallel to the radial plane of the turret shaft 130. In one example, the separation segment 1431 corresponds to the feeding side and the discharging side of the test turret 100, and the test segment 1432 corresponds to the movement track of the cup 600 between the feeding side and the discharging side.

[0092] In the embodiment of the present application, the connection segment 1433 is used to connect the separation segment 1431 and the test segment 1432. It can be understood that at least two connection segments 1433 are provided so that the test segment 1432 and the separation segment 1431 are connected end to end. The extending direction of the connection segment 1433 is set at an angle to the preset direction X, that is, one end of the connection segment 1433 is far from the test turntable 110 and connects the separation segment 1431, and the other end is close to the test turntable 110 and connects the test segment 1432. In addition, an arc chamfer can be provided at the connection position of the connection segment 1433 and the test segment 1432 / separation segment 1431. The settings of the connection segment 1433 and the arc chamfer both contribute to the smooth movement of the connecting member 141 along the track 143.

[0093] In the technical solution of the embodiment of the present application, by providing a separation section 1431 and a test section 1432, when the connecting member 141 moves to the separation section 1431, the test assembly 120 can be lifted to facilitate the loading and unloading of the battery cell 700; when the connecting member 141 moves to the test section 1432, it can drive the test assembly 120 into contact with the battery cell 700 to facilitate the test assembly 120 to perform tests.

[0094] To facilitate the test assembly 120 to test the battery cell 700, referring to Figure 5 and Figure 6 in some possible embodiments of the present application, the test section 1432 has a first dimension L1 along the circumferential direction of the track member 142, and the separation section 1431 has a second dimension L2 along the circumferential direction of the track member 142, and the first dimension L1 is greater than the second dimension L2.

[0095] In the embodiment of the present application, the dimension of the track 143 along the circumferential direction of the track member 142 can also be understood as the dimension of the movement path of the connecting member 141 along the track 143. The first dimension L1 of the test section 1432 along the circumferential direction of the track member 142 is greater than the second dimension L2 of the separation section 1431 along the circumferential direction of the track member 142. During a uniform circular motion process of the connecting member 141 along the track 143, the time when the connecting member 141 is in the test section 1432 is greater than the time when it is in the separation section 1431, that is, the time for the test assembly 120 to contact the corresponding battery cell 700 is longer, and there is sufficient time to complete the test, so that more types of tests can be performed.

[0096] In the technical solution of the embodiment of the present application, since the first dimension L1 of the test section 1432 is greater than the second dimension L2 of the separation section 1431, the test assembly 120 can have more time to contact the battery cell 700 to facilitate the test.

[0097] To facilitate the movement of the connecting member 141 along the track 143, referring to Figure 3 and Figure 4 in some possible embodiments of the present application, the lifting assembly 140 further includes a rotating member 144, the track 143 is a track groove opened on the outer peripheral side of the track member 142, the rotating member 144 is rotatably arranged in the track groove, and the connecting member 141 is connected to the rotating member 144.

[0098] In the embodiment of the present application, the rotating member 144 can be an elastic rotating member 144, which has good adaptability and movement smoothness. The rotating member 144 can also be a rigid rotating member 144, which has good support stability. The connecting member 141 can be arranged parallel to the 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 close to the test assembly 120 is connected to the test assembly 120.

[0099] In the embodiments of the present application, the rotating member 144 may be a roller, a roller, a ball, etc., and the embodiments of the present application do not limit this. The connecting member 141 and the rotating member 144 may be fixedly connected or rotatably connected, and the same connecting member 141 may be connected to one or more rotating members 144. It should be noted that the rotating member 144 may not be provided, that is, the connecting member 141 directly slides in the track groove.

[0100] In the embodiments of the present application, the track groove may be unidirectionally limited, that is, the rotating member 144 contacts the inner wall of the track groove on one side along the preset direction X and is supported by the corresponding inner wall of the track groove, and the other side does not contact the inner wall of the track groove. The track groove may also be bilaterally limited, that is, the rotating member 144 contacts the opposite inner walls of the track groove on both sides along the preset direction.

[0101] In addition, a flange may be provided at the opening of the track groove so that the size of the opening is small, and the rotating member 144 can be restricted in the track groove to reduce the possibility of the rotating member 144 coming out of the track groove.

[0102] In the technical solution of the embodiments of the present application, the track 143 is in the form of a track groove, which can limit the rotating member 144 therein to improve the guiding accuracy, and the setting of the rotating member 144 can reduce friction so that the connecting member 141 can move smoothly along the track 143.

[0103] For the convenience of the sliding connection of the connecting member 141, referring to Figure 1 、 Figure 7 and Figure 8 , in some possible embodiments of the present application, 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, and the connecting member 141 is slidably connected to the outer peripheral side of the support member 150.

[0104] In the embodiments of the present application, 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.

[0105] In the embodiments of the present application, the support member 150 may be sleeved on the outer peripheral side of the turret shaft 130, and the support member 150 and the turret shaft 130 are fixed by means of threaded connection, snap connection, fastener connection, etc. Exemplarily, the support member 150 is locked to the turret shaft 130 by a plurality of fasteners, and the plurality of fasteners are uniformly arranged around the turret shaft 130 to provide stable connection and facilitate disassembly, installation and maintenance.

[0106] In the embodiments of the present application, the radial dimension of the support member 150 may be greater than, equal to, or less than the radial dimension of the test turntable 110; the radial dimension of the support member 150 may be greater than, equal to, or less than the radial dimension of the track member 142. Exemplarily, 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 as to facilitate the connection of the connecting member 141 to the track member 142 and the support member 150 respectively.

[0107] In the embodiments of the present application, a chute may be provided on the support member 150, and the connecting member 141 is slidably connected in the chute. Alternatively, a guiding member and a sliding member assembly are provided between the support member 150 and the connecting member 141, and the support member 150 provides support and limitation for the connecting member 141 to improve the movement accuracy of the test assembly 120 along the preset direction X.

[0108] In the technical solution of the embodiments of the present application, by providing the support member 150 for the sliding connection of the connecting member 141, since the support member 150 has a relatively large radial dimension relative to the turret shaft 130, it can provide better support for the connecting member 141 and also provide a larger movement space for the test assembly 120.

[0109] To balance weight reduction and support stability, referring to Figure 7 、 Figure 8 and Figure 9 in some possible embodiments of the present application, the support member 150 includes a support disk 151 and a support sleeve 152. The support disk 151 is fixed to the turret shaft 130, the support sleeve 152 is sleeved on the outer peripheral side of the support disk 151, the connecting member 141 is movably connected to the support sleeve 152, and along the axis direction of the turret shaft 130, the dimension of the support sleeve 152 is greater than the dimension of the support disk 151.

[0110] In the embodiments of the present application, the movable connection between the connecting member 141 and the support sleeve 152 means that the two can move relative to each other, and their connection can be a sliding connection, a flexible connection, a transmission connection, etc.

[0111] In the embodiments of the present application, the support disk 151 and the support sleeve 152 may be connected by means of snap connection, bonding, welding, etc. Exemplarily, the support disk 151 and the support sleeve 152 are integrally formed. Among them, the dimension of the support sleeve 152 along the preset direction X is greater than the dimension of the support disk 151 along the preset direction X, so that the axial cross-section of the support member 150 has an "H"-shaped structure, which has both high structural strength and a large support surface.

[0112] In the embodiments of the present application, the support disk 151 is fixed to the turret shaft 130 through fasteners, and the outer peripheral side of the support sleeve 152 is used to support the connecting member 141, so that when the connecting member 141 corresponds to the movement track of the cup holder 600, the connecting member 141 can be arranged parallel to the preset direction X and be stably supported by the support sleeve 152.

[0113] In the technical solution of the embodiments of the present application, the support member 150 is provided as two parts, namely a support disk 151 and a support sleeve 152. The support sleeve 152 can provide a relatively large support size to facilitate the stable connection of the connecting member 141, and the axial dimension of the support disk 151 is small, which is also beneficial for weight reduction.

[0114] In order to stably guide the movement of the connecting member 141, referring to Figure 3 、 Figure 4 and Figure 7 in some possible embodiments of the present application, the test turret 100 further includes a guiding assembly 160. The guiding assembly 160 includes a guiding member 161 and a sliding member 162. The guiding member 161 is connected to the outer peripheral side of the support member 150. The sliding member 162 is connected to the guiding member 161 and moves along the guiding member 161. The connecting member 141 is connected to the sliding member 162, and the support sleeve 152 extends to both ends of the guiding member 161 along the movement direction of the sliding member 162.

[0115] In the embodiments of the present application, the connection between the sliding member 162 and the guiding member 161 can be that the guiding member 161 is provided with a sliding groove, and a part of the sliding member 162 extends into the sliding groove for sliding. Or, the sliding member 162 is sleeved outside the guiding member 161 for sliding. Exemplarily, sliding grooves are respectively arranged on both sides of the guiding member 161 along the circumferential side of the support member 150. The sliding grooves extend along the preset direction X. The sliding member 162 is sleeved outside the guiding member 161, and the sliding member 162 has two sliding parts, and the two sliding parts respectively extend into the two sliding grooves to realize the sliding connection between the two, which has better guiding accuracy and connection stability.

[0116] In the embodiments of the present application, the sliding member 162 moves along the guiding member 161. The extending direction of the guiding member 161 can be arranged parallel to the preset direction X, and the sliding member 162 slides relative to the guiding member 161 parallel to the preset direction X.

[0117] In the embodiments of the present application, the guiding member 161 can be fixed to the outer peripheral side of the support sleeve 152 by means of bonding, clamping, welding, fastener connection, etc., and the dimensions of the guiding 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 guiding member 161. In an example, a clamping groove 153 is formed on the support sleeve 152, and the guiding member 161 is clamped in the clamping groove 153.

[0118] In the technical solution of the embodiment of the present application, by providing a guiding component 160, the slide rail of the guiding component 160 is fixed to the support sleeve 152, and the support sleeve 152 extends to both ends of the guiding member 161, which can provide stable support for the guiding member 161. The connecting member 141 is slidably connected to the guiding member 161 through the sliding member 162, and under the guidance of the guiding component 160, it can move smoothly along the preset direction X.

[0119] For the convenience of disassembling, assembling and maintaining the turret 100 during testing, referring to Figure 7 、 Figure 8 and Figure 9 in some possible embodiments of the present application, the test turret 100 further includes a locking component 170. The locking component 170 is connected to the sliding member 162. The locking component 170 includes at least two relatively movable locking parts 171 for locking and fixing the connecting member 141.

[0120] In the embodiment of the present application, the locking component 170 can be fixedly connected to the sliding member 162 or movably connected to the sliding member 162. Exemplarily, the locking component 170 is fixedly connected to the sliding member 162 through 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.

[0121] In the embodiment of the present application, the locking component 170 can include two or more locking parts 171. A clamping space 172 is formed between the locking parts 171. Different locking parts 171 can be independently arranged or connected to each other. In one example, the two locking parts 171 are respectively slidably connected to the sliding member 162. In another example, the two locking parts 171 are connected to each other, and the locking part 171 is made of an elastic material to move relatively. A cylindrical clamping space 172 is formed between the two locking parts 171 to be adapted to the connecting member 141, and the connecting member 141 is clamped in the clamping space 172.

[0122] On this basis, the two locking parts 171 can be fixed by means of clamping or fastener connection to clamp and lock the connecting member 141 therein. Exemplarily, connection holes are provided at the mutually remote ends of the two locking parts 171. When the locking parts 171 approach each other to clamp the connecting member 141 tightly, the fastener passes through the connection holes of the two locking parts 171 to relatively fix the two locking parts 171.

[0123] In the technical solution of the embodiment of the present application, by providing the locking component 170, the locking component 170 locks and fixes the connecting member 141 through the locking part 171, which facilitates the disassembly and assembly of the connecting member 141 relative to the guiding component 160, so as to facilitate the maintenance of the test component 120, the test turntable 110, etc.

[0124] To improve the test efficiency, referring to Figure 2 andFigure 3 In some possible embodiments of the present application, the test turntable 110 includes a receiving groove 111 for receiving the receiving cup 600. There are at least two receiving grooves 111, and at least part of the receiving grooves 111 are correspondingly provided with test components 120.

[0125] In the embodiments of the present application, the test turntable 110 may include a turntable part and a retaining part. The turntable part rotates along with the turret shaft 130. The retaining part is arranged on the outer peripheral side of the turntable part and is fixed relative to the base of the test device, that is, the retaining part does not rotate along with the turret shaft 130. The receiving groove 111 is opened on the outer peripheral side of the turntable part and has a semi-circular or semi-elliptical opening. The receiving cup 600 enters the receiving groove 111 and is enclosed by the retaining part and the inner wall of the receiving groove 111 to move along with the rotation of the turntable part.

[0126] In the embodiments of the present application, corresponding to the feeding side or the discharging side of the test turret 100, the retaining part is provided with an opening to facilitate the receiving cup 600 to enter the test turntable 110 from the opening on the feeding side and leave the test turntable 110 from the opening on the discharging side.

[0127] In the embodiments of the present application, multiple receiving grooves 111 may be equidistantly distributed along the circumference of the test turntable 110, which is convenient for the uniform stress of the test turret 100 and also convenient for the uniform transportation of the receiving cup 600.

[0128] In the embodiments of the present application, according to the design requirements, the receiving grooves 111 on the turntable part may all be used to receive the receiving cup 600, or some of them may be used to receive the receiving cup 600. The test components 120 are correspondingly arranged at the positions of the receiving grooves 111 for receiving the receiving cup 600, and the test components 120 can test the battery cells 700 in the receiving grooves 111.

[0129] In order to improve the test efficiency, in some embodiments, the test components 120 are correspondingly arranged at the positions of all the receiving grooves 111 for receiving the receiving cup 600. It can be understood that in the case of having at least two test components 120, there are also at least two connecting pieces 141 corresponding to the test components 120 one by one.

[0130] The technical solution of the embodiments of the present application, by providing at least two receiving grooves 111, enables the test turntable 110 to simultaneously transport 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 test efficiency.

[0131] For the convenience of electrical connection of the test components 120, referring to Figure 1 and Figure 12, in some possible embodiments of the present application, 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 wire harness. The first ring body 410 rotates relative to the second ring body 420 and is electrically connected thereto. The second ring body 420 is relatively fixed to the test turntable 110. The wire harness is connected between the second ring body 420 and the test component 120.

[0132] In the embodiments of the present application, the second ring body 420 is relatively fixed to the test turntable 110. Specifically, the axes of the two overlap. The second ring body 420 is connected to the test turntable 110 by means of clamping, bonding, welding, interference fit, etc. The second ring body 420 can move synchronously with the test turntable 110.

[0133] In the embodiments of the present application, the power transmission mechanism 400 can be a 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 test device. The first ring body 410 is connected to a power supply device, a test host, etc. by a wire harness. The second ring body 420 is sleeved on the outer peripheral side of the first ring body 410. The first ring body 410 rotates coaxially with the test turntable 110. The test component 120 is connected to the second ring body 420 by a wire harness and is thus electrically connected to a power supply device, a test host, etc.

[0134] In the embodiments of the present application, the connection between the first ring body 410 and the second ring body 420 can be single-path electrical connection or multi-path electrical connection. For example, the first ring body 410 includes at least two conductive grooves insulated from each other at intervals along a preset direction X, and the second ring body 420 includes at least two conductive parts insulated from each other at intervals along the preset direction X. The at least two conductive parts slide in the at least two conductive grooves one by one to form at least two paths of electrical connection. Each conductive part is connected to a wire harness respectively. It can be understood that the number of electrical connection paths in the power transmission mechanism 400 corresponds to the number of test components 120.

[0135] In the embodiments of the present application, the power transmission mechanism 400 can be arranged between the support member 150 and the test turntable 110, or can also be arranged between the support member 150 and the track member 142. In one example, the test turntable 110 is arranged on the side of the track member 142 away from the test turntable 110.

[0136] In some possible embodiments, the power transmission component can also be not provided, and a wireless connection is used to establish an electrical connection between the test probe 121 and the test host and the power supply device. Among them, the wireless connection can be electromagnetic power transmission, Bluetooth, XingFlash, wireless network, etc.

[0137] In the technical solution of the embodiment of the present application, by providing a power transmission mechanism 400, the power transmission mechanism 400 includes a first ring body 410 and a second ring body 420 which are electrically connected. The second ring body 420 is connected to the test component 120 through a wire harness and can rotate synchronously to avoid the wire harness being wound during rotation, optimizing the electrical connection mode of the test component 120.

[0138] For the convenience of connecting the test probe 121, referring to Figure 4 、 Figure 10 and Figure 11 , in some possible embodiments of the present application, the test component 120 includes a test probe 121 and an adapter 122. The adapter 122 has a set extension direction. The dimension of the adapter 122 along the extension direction is greater 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.

[0139] In the embodiment of the present application, the extension direction of the adapter 122 is the direction of its maximum dimension. For example, if the adapter 122 is a rod-shaped structure, the extension direction is its axial direction; or for another example, if the adapter 122 is a plate-shaped structure or a block-shaped structure, the extension direction is its length direction.

[0140] In the embodiment of the present application, the adapter 122 can be a rectangular plate-shaped structure. One end of the adapter 122 is connected to the lifting component 140. For example, one end of the adapter 122 along the length direction is fixedly connected to the lower end of the connecting piece 141, and the other end of the adapter 122 along the length direction is used to install the test probe 121. Wherein, the adapter 122 and the connecting piece 141 can be bonded, welded, clamped, etc. For example, the adapter 122 is provided with an assembly hole 123, and the end of the connecting piece 141 extends into the assembly hole 123 to achieve the connection.

[0141] In the embodiment of the present application, the test probe 121 can be fixed to the adapter 122 by means of clamping, bonding, welding, threaded connection, fastener connection, etc. For example, the adapter 122 is provided with a fixing hole 124, and the fixing hole 124 is a through hole. The test probe 121 passes through the fixing hole 124, which can not only provide a stable support and limit for the test probe 121, but also facilitate the test probe 121 to be connected to the power transmission mechanism 400 through a wire harness.

[0142] In addition, a convex portion 125 is provided at the part of the adapter 122 connecting the test probe 121, thereby increasing the radial dimension of the fixing hole 124 to increase the connection area between the test probe 121 and the adapter 122 and improve the stability of the test probe 121.

[0143] In the technical solution of the embodiment of the present application, by providing an adapter 122, the test probe 121 is connected to one end of the adapter 122, which is not likely to interfere with other components of the test turret 100, facilitating the connection of the test probe 121.

[0144] To make the structure of the test turret 100 more compact, referring to Figure 12 , in some possible embodiments of the present application, the test turntable 110 is set with a diameter direction facing the adapter 122, and the extending direction of the adapter 122 is set at an angle with the corresponding diameter direction.

[0145] In the embodiment of the present application, the test turntable 110 may be a disc structure, and the test turntable 110 has a plurality of diameter directions perpendicular to its axial direction. It can be understood that the plurality of diameter directions are different; along the axial projection of the test turntable 110, some diameter directions pass through the projection of the adapter 122, and the extending 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 extending direction of the adapter 122 is not parallel to the corresponding diameter direction.

[0146] In the embodiment of the present application, the test turntable 110 has an upper surface close to the test assembly 120, and the extending direction of the adapter 122 may be parallel to the upper surface of the test turntable 110, or may be set at an acute angle or an obtuse angle with the upper surface.

[0147] In the embodiment of the present application, the adapter 122 is parallel to the test turntable 110, that is, the length direction and the width direction 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 the preset direction X. The length direction of the adapter 122 may be set along the radial or circumferential direction of the test turntable 110, or may be set along the remaining directions in the radial plane of the test turntable. Among them, the length direction of the adapter 122 is along the circumferential direction of the test turntable 110. Specifically, a plurality of adapters 122 are connected end to end along the circumferential direction of the test turntable 110, and the extension lines of the long sides of the adapters 122 form a tangent or a secant of the circumscribed circle of the test turntable 110.

[0148] In the embodiment of the present application, the test probe 121 may be set along the preset direction X, or may be perpendicular to the preset direction X, or the test probe 121 may be inclined. In addition, the test probe 121 may be one, two or more than two. Two test probes 121 may be arranged along the radial direction of the test turntable 110, or may be arranged along the circumferential direction of the test turntable 110. More than two test probes 121 may be arranged in the form of a triangle, a circle, a square, etc. Exemplarily, two test probes 121 are distributed at intervals along the length direction of the adapter 122.

[0149] In the technical solution of the embodiment of the present application, the adapter 122 is parallel to the test turntable 110. On the one hand, it is convenient for connecting the test probe 121 to the adapter 122. On the other hand, the extension direction of the adapter 122 is set at an angle with the corresponding diameter direction, so that the dimension of the connecting member 141 can be set smaller, thereby making the structure of the test turret 100 more compact.

[0150] Referring to Figure 1 , in some possible embodiments of the present application, the test device further includes a feeding turntable 200 and a discharging turntable 300.

[0154] In the embodiment of the present application, the driving mechanism can be a driving member that outputs rotational motion of the output shaft such as a motor or a rotary cylinder, or a driving member that outputs linear motion of the output shaft such as a hydraulic cylinder, a cylinder, or an electric telescopic rod. Among them, the motor can be a servo motor, a stepper motor, etc. Exemplarily, the driving mechanism is a motor.

[0155] In the embodiments of the present application, the feeding turntable 200 corresponds to the feeding side of the testing turntable 110, and the discharging turntable 300 corresponds to the discharging side of the testing turntable 110. The feeding side and the discharging side of the testing turntable 110 may be symmetrically distributed, or alternatively, the feeding side and the discharging side are arranged at an acute or obtuse angle interval. Wherein, the movement path of the cup holder 600 is arranged along the major arc between the feeding side and the discharging side, so that the testing assembly 120 has more contact time with the battery cell 700.

[0156] In the technical solution of the embodiments of the present application, the synchronization mechanism 500 can drive the testing turntable 110, the feeding turntable 200, and the discharging turntable 300 to move synchronously, so as to improve the cooperation degree among the three, facilitate the transfer of the cup holder 600 among the three, and the setting of the synchronization mechanism 500 only requires a set of driving mechanisms, which can also simplify the structure.

According to different process sequences, the production device 800 has various possible forms.

[0159] In the embodiments of the present application, the transfer device has various possible forms. For example, the transfer device is a conveyor belt, which has a simple structure and high transportation efficiency. Or, the transfer device is an arm-type robot, which can perform more complex operations.

[0160] In the technical solution of the embodiments of the present application, the battery withstand voltage testing system includes the above-mentioned testing device. The testing assembly 120 is connected to the testing turntable 110 and rotates synchronously with the testing turntable 110, that is, the testing assembly 120 moves synchronously with the cup holder 600 and the battery cell 700 on the testing turntable 110. The testing assembly 120 can maintain relative rest with the battery cell 700. While the testing turntable 110 transports the battery, the testing assembly 120 can test the battery cell 700. This testing process does not need to pause the cup holder 600 and the battery cell 700, ensuring the continuity of the transfer process of the battery cell 700, and the transfer and testing are carried out synchronously, which can save testing time and optimize the production rhythm.

A feed turntable 200 is arranged on the feed side of the test turntable 110, and a discharge turntable 300 is arranged on the discharge side of the test turntable 110. The cup holders 600 move along the feed turntable 200, the test turntable 110, and the discharge turntable 300 in sequence. The test turret 100 includes a turret shaft 130. The lower end of the turret shaft 130 is connected to a synchronization mechanism 500. The synchronization mechanism 500 is respectively connected to the feed turntable 200, the discharge turntable 300, and a driving mechanism, so that the driving mechanism drives the feed turntable 200, the test turntable 110, and the discharge turntable 300 to move synchronously, that is, to move at the same linear velocity.

[0162] Among them, a support member 150 is arranged on the upper side of the test turntable 110. A guide assembly 160 is connected to the outer peripheral side of the support member 150.

The test assembly 120 is stationary relative to the battery cell 700 on the test turntable 110, which is convenient for the test assembly 120 to test the battery cell 700.
