Description

Technical Field

[0001] The present application relates to the technical field of battery testing, and in particular to a testing device and a battery withstand voltage testing system. Background Art

[0002] During the battery production process, it is usually necessary to test the battery cells, such as performing a withstand voltage test using electrical equipment, to determine whether the insulation and withstand voltage of the battery cells meet the requirements. The test efficiency in the related technology is low, which affects the production cycle. Summary of the invention

[0003] In order 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 the present application provides a testing device, including a testing turret, which is provided with a feeding side and a discharging side, and the testing turret includes a testing turntable and a testing assembly, the testing turntable is used to transfer a supporting cup between the feeding side and the discharging side, and the supporting cup is used to carry a battery cell; the testing assembly is connected to the testing turntable and moves synchronously with the testing turntable, and the testing assembly and the testing turntable are relatively stationary along the moving direction; the testing assembly is used to test the battery cells in the testing turntable.

[0005] In the technical solution provided in the embodiment of the present application, the test turret includes a test turntable and a test assembly. The test turntable can drive the support cup to move from the feed side to the discharge side to realize the transportation of the support cup and the corresponding battery cell. The test assembly is connected to the test turntable and moves synchronously with the test turntable, that is, the test assembly moves synchronously with the support cup and the battery cell on the test turntable. The test assembly and the battery cell can remain relatively still. While the test turntable transports the battery, the test assembly can test the battery cell. The test process does not require pausing the support cup and the battery cell, ensuring the continuity of the battery cell transportation process, and the transportation and testing are carried out simultaneously, saving time, thereby speeding up the production rhythm of the battery cell and improving production efficiency. Compared with the solution in the related art that the battery cell needs to be paused before testing, the test assembly of the present application moves synchronously with the test turntable and tests the battery cell while it is being transported, saving test time, speeding up the production rhythm, and improving production efficiency.

[0006] In some embodiments of the present application, the test turret also includes a turret shaft and a lifting assembly, the lifting assembly and the test turntable are coaxially connected to the turret shaft, the test assembly is connected to the lifting assembly, and the lifting assembly is used to drive the test assembly close to or away from the test turntable.

[0007] Here, by setting up a lifting assembly, the lifting assembly can drive the test assembly to move. In the process of transporting the battery cell in or out of the test turntable, the lifting assembly drives the test assembly away from the battery cell, reducing the possibility of collision between the test assembly and the battery cell; when testing is required, the lifting assembly drives the test assembly close to the battery cell so that the test assembly can test the battery cell, which not only facilitates the test but also protects the test assembly and the battery cell.

[0008] In some embodiments of the present application, the lifting assembly includes a connecting member, which respectively connects the test assembly and the turret shaft, and the connecting member and the turret shaft are relatively rotatable; or, the connecting member and the turret shaft are relatively translated.

[0009] Here, by setting a connecting piece, the connecting piece and the turret shaft are set to rotate relative to each other to form a lever structure, which can not only drive the test assembly to rise and fall along the axial direction of the turret shaft, but also drive the test assembly to move radially along the turret shaft; the connecting piece can also translate relative to the turret shaft to drive the test assembly to rise and fall, and the structure is simpler.

[0010] In some embodiments of the present application, the lifting assembly also includes a track member, which is coaxially connected to the turret shaft and arranged to rotate relatively, and a circumferential track is arranged on the track member; the track includes at least two track segments, and along the axial direction of the turret shaft, at least two track segments have different distances from the test turntable, and the connecting member rotates with the turret shaft and moves along the track to drive the test assembly to approach or move away from the test turntable.

[0011] Here, a track member is provided with a track. When the connecting member rotates along with the turret shaft, the connecting member will also move along the track. Since the track includes at least two track segments with different spacings from the test turntable, the connecting member can rise or fall on the corresponding track segment, thereby driving the test assembly to rise and fall. Since the lifting and lowering of the test assembly is related to the rotation of the test turntable, it has a higher matching accuracy.

[0012] In some embodiments of the present application, 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 spacing between the separation segment and the test turntable is greater than a second spacing between the test segment and the test turntable. When the connecting member moves to the test segment, the test assembly contacts the battery cell at the corresponding position.

[0013] Here, by setting up a separation section and a test section, the connector moves to the separation section to lift the test assembly to facilitate the transport of the battery cell in and out; the connector moves to the test section to drive the test assembly to contact the battery cell to facilitate testing of the test assembly.

[0014] In some embodiments of the present application, the test segment has a first size along the circumference of the track member, the separation segment has a second size along the circumference of the track member, and the first size is greater than the second size.

[0015] Here, since the first size of the testing section is larger than the second size of the separating section, the testing assembly can have more time to contact with the battery cell, so as to facilitate the test.

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

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

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

[0019] Here, a support member is provided, which is used for the sliding connection of the connecting member. Since the support member has a larger radial dimension relative to the turret shaft, it can provide better support for the connecting member and also provide a larger movement space for the test assembly.

[0020] In some embodiments of the present application, the support member 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 peripheral side of the support plate, the connecting member is movably connected to the support sleeve, and along the axial direction of the turret shaft, the size of the support sleeve is larger than the size of the support plate.

[0021] Here, the support member is configured as two parts, a support disc and a support sleeve. The support sleeve can provide a larger support dimension to facilitate stable connection of the connector, and the axial dimension of the support disc is smaller, which is also conducive to weight reduction.

[0022] In some embodiments of the present application, the test turret also includes a guide assembly, the guide assembly includes a guide member and a sliding member, the guide member is connected to the outer peripheral side 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.

[0023] Here, by setting up 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 member, which can provide stable support for the guide member. The connecting member is connected to the guide member through a sliding member, and under the guidance of the guide component, it can move smoothly along the preset direction.

[0024] In some embodiments of the present application, the test turret further includes a locking assembly, which is connected to the sliding member, and the locking assembly includes at least two locking parts that can move relative to each other and are used to lock and fix the connecting member.

[0025] Here, by providing a locking assembly, the locking assembly locks and fixes the connector through a locking portion, making it easy to disassemble and assemble the connector relative to the guide assembly, so as to facilitate maintenance of the test assembly, the test turntable, etc.

[0026] In some embodiments of the present application, the test turntable includes receiving slots for receiving the tray cups, there are at least two receiving slots, and at least some of the receiving slots are correspondingly provided with test components.

[0027] Here, by providing at least two receiving slots, the test turntable can transport multiple battery cells at the same time, and at least two test assemblies can test multiple battery cells on the test turntable, thereby improving the test efficiency.

[0028] In some embodiments of the present application, the testing device also includes a power transmission mechanism, which includes a first ring body, a second ring body and a conductive wire bundle. 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 conductive wire bundle is connected between the second ring body and the test component.

[0029] Here, by setting up a power transmission mechanism, the power transmission mechanism includes a first ring body and a second ring body that are electrically connected. The second ring body is connected to the test component through a conductive wire bundle and can rotate synchronously to avoid the guide wire bundle being entangled during rotation, thereby optimizing the electrical connection method of the test component.

[0030] In some embodiments of the present application, the test assembly includes a test probe and an adapter, the adapter has a set extension direction, the size of the adapter along the extension direction is larger than the size of the adapter along other directions, and 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 an adapter, the test probe is connected to one end of the adapter, which is not easy to interfere with other components of the test turret, and the connection of the test probe is convenient.

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

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

[0035] In the technical solution of the embodiment of the present application, the battery withstand voltage test system includes the above-mentioned test device, and the test assembly is connected to the test turntable and moves synchronously with the test turntable, that is, the test assembly moves synchronously with the support cup and battery cell on the test turntable, and the test assembly and the battery cell can remain relatively still. While the test turntable transports the battery, the test assembly can test the battery cell. The test process does not require pausing the support cup and the battery cell, thereby ensuring the continuity of the battery cell transportation process. The transportation and testing are carried out simultaneously, which can save testing time and optimize the production rhythm. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Below, this application is described in detail.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Reference Figure 1 and Figure 2 The test device of the embodiment of the present application includes a test turret 100, which is provided with a feed side and a discharge side. The test turret 100 includes a test turntable 110 and a test assembly 120. The test turntable 110 is used to transfer a support cup 600 between the feed side and the discharge side, and the support cup 600 is used to carry a 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, and the test assembly 120 is used to test the battery cell 700 in the test turntable 110.

[0051] In the embodiment of the present application, the support cup 600 moves with the test turntable 110, thereby moving from the feed side of the test turret 100 to the discharge side, and is used to carry the battery cell 700. The inner contour of the support 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 a cylindrical battery, or set to a square shape to accommodate a square battery. The outer contour of the support cup 600 can be set to a circular shape, a square shape, an elliptical shape, etc. For example, the outer contour of the support cup 600 is set to a circular shape, which has a strong ability to withstand collisions and is also convenient for switching to different turntables.

[0052] 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 direction at the same time. The movement of the test assembly 120 following the test turntable 110 can be rotational movement around a fixed axis, reciprocating movement along a single track, or cyclic movement along a cyclic track.

[0053] 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. The positions and speeds of the two on the moving track correspond to each other, and the test assembly 120 is 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.

[0054] When the test assembly 120 rotates with the test turntable 110, the test assembly 120 and the test turntable 110 have the same rotation axis (i.e., the axes of the two are arranged to overlap), and move at the same angular velocity to remain relatively still. For example, the test assembly 120 and the test turntable 110 rotate at the same angular velocity, so that the test assembly 120 can be stationary relative to the test turntable 110, and then the test assembly 120 and the battery cell 700 at the corresponding position are relatively stationary. Among them, the test assembly 120 and the test turntable 110 can be directly connected or indirectly connected.

[0055] 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 600 to move from the feed side to the discharge side to realize the transportation of the cup 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 600 and the battery cell 700 on the test turntable 110, and the test assembly 120 and the battery cell 700 can remain relatively still. While the test turntable 110 transports the battery, the test assembly 120 can test the battery cell 700. The test process does not need to pause the cup 600 and the battery cell 700, ensuring the continuity of the transportation process of the battery cell 700, and the transportation and testing are carried out simultaneously, saving time, thereby speeding up the production rhythm of the battery cell 700 and improving production efficiency.

[0056] Compared with the solution in the related art that the battery cell 700 needs to be paused before testing, the test component 120 of the present application moves synchronously with the test turntable 110, and tests are performed while the battery cell 700 is being transported, which saves test time, speeds up production rhythm, and improves production efficiency.

[0057] In order to protect the test assembly 120 and the battery cell 700, refer to Figure 3 and Figure 4 In some possible embodiments of the present application, the test turret 100 also 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. The test assembly 120 is connected to the lifting assembly 140. The lifting assembly 140 is used to drive the test assembly 120 to move closer to or away from the test turntable 110.

[0058] 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. For example, 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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 .

[0068] 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.

[0069] 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 also includes a track member 142, which is coaxially connected to the turret shaft 130 and is arranged to rotate relatively, and a circumferential track 143 is arranged on the track member 142; the track 143 includes at least two track segments, and along the axial direction of the turret shaft 130, at least two track segments have different spacings from the test turntable 110, and the connecting member 141 rotates with 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.

[0070] In the embodiment of the present application, the track member 142 is coaxially arranged with the turret shaft 130, and the two are arranged to rotate relative to each other, that is, the track member 142 does not rotate with the turret shaft 130, and the track member 142 can be fixed to the base of the test device. Due to the relative movement between the two, when the turret shaft 130 drives the connecting member 141 to rotate, the connecting member 141 will move relative to the track member 142.

[0071] In the embodiment of the present application, the track member 142 is a disc structure, and the track 143 can be arranged on the outer peripheral side of the track member 142, or on the upper surface or lower surface of the track member 142 along the preset direction X. The track 143 surrounds the central axis of the turret shaft 130 in the circumferential direction to form a closed track, and the track 143 can be an annular structure, so that the connecting member 141 will circulate along the track 143 during the rotation of the turret shaft 130.

[0072] In the embodiment of the present application, the track 143 may include two or more track segments. It can be understood that when the distance between the track segment through which the connector 141 passes and the test turntable 110 is small, the connector 141 drives the test component 120 to approach 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 distance between the track segment through which the connector 141 passes and the test turntable 110 is large, the connector 141 drives the test component 120 away from the test turntable 110, and the test component 120 is separated from the battery cell 700 on the test turntable 110, so that the battery cell 700 can enter and exit the test turntable 110.

[0073] The technical solution of the embodiment of the present application is to set a track member 142, and the track member 142 is provided with a track 143. When the connecting member 141 rotates 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 spacings from the test turntable 110, the connecting member 141 can rise or fall on the corresponding track segment, thereby driving the test component 120 to be lifted and lowered. Since the lifting and lowering of the test component 120 is related to the rotation of the test turntable 110, it has a higher matching accuracy.

[0074] In order to facilitate the lifting and lowering of the test assembly 120 along the track 143, refer 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 connecting segment 1433 connecting the separation segment 1431 and the test segment 1432. Along the axial direction of the turret shaft 130, a first spacing H1 between the separation segment 1431 and the test turntable 110 is greater than a second spacing H2 between the test segment 1432 and the test. When the connector 141 moves to the test segment 1432, the test assembly 120 contacts the battery cell 700 at the corresponding position.

[0075] In the embodiment of the present application, the first spacing H1 between the separation section 1431 and the test turntable 110 is greater than the second spacing H2 between the test section 1432 and the test turntable 110. It can be understood that when the connector 141 moves to the separation section 1431, the connector 141 drives the test assembly 120 relatively away from the test turntable 110, so that the test assembly 120 is separated from the corresponding battery cell 700; when the connector 141 moves to the test section 1432, the connector 141 drives the test assembly 120 relatively close to the test turntable 110, so that the test assembly 120 is in contact with the corresponding battery cell 700.

[0076] In the embodiment of the present application, 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 motion trajectory of the support cup 600 between the feed side and the discharge side.

[0077] In the embodiment of the present application, the connecting section 1433 is used to connect the separation section 1431 and the test section 1432. It can be understood that at least two connecting sections 1433 are provided so that the test section 1432 and the separation section 1431 are connected end to end. The extending direction of the connecting section 1433 is set at an angle to the preset direction X, that is, one end of the connecting section 1433 is away from the test turntable 110 to connect the separation section 1431, and the other end is close to the test turntable 110 to connect the test section 1432. In addition, the connection position of the connecting section 1433 and the test section 1432 / separation section 1431 can also be provided with an arc chamfer, and the setting of the connecting section 1433 and the arc chamfer both help the connector 141 to move smoothly along the track 143.

[0078] According to the technical solution of the embodiment of the present application, by setting a separation section 1431 and a test section 1432, the connector 141 moves to the separation section 1431 to lift the test assembly 120 to facilitate the transportation of the battery cell 700 in and out; the connector 141 moves to the test section 1432 to drive the test assembly 120 to contact the battery cell 700 to facilitate testing of the test assembly 120.

[0079] In order to facilitate the testing component 120 to test the battery cell 700, refer to Figure 5 and Figure 6 In some possible embodiments of the present application, the test segment 1432 has a first dimension L1 along the circumference of the track member 142 , the separation segment 1431 has a second dimension L2 along the circumference of the track member 142 , and the first dimension L1 is greater than the second dimension L2.

[0080] In the embodiment of the present application, the size of the track 143 along the circumference of the track member 142 can also be understood as the size of the movement path of the connector 141 along the track 143. The first size L1 of the test section 1432 along the circumference of the track member 142 is greater than the second size L2 of the separation section 1431 along the circumference of the track member 142. When the connector 141 completes a uniform cycle along the track 143, the time the connector 141 is in the test section 1432 is greater than the time it is in the separation section 1431, that is, the time the test assembly 120 contacts 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.

[0081] According to the technical solution of the embodiment of the present application, since the first size L1 of the test section 1432 is larger than the second size L2 of the separation section 1431 , the test assembly 120 can have more time to contact the battery cell 700 to facilitate testing.

[0082] In order to facilitate the movement of the connecting member 141 along the track 143, refer to Figure 3 and Figure 4In some possible embodiments of the present application, the lifting assembly 140 also 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 set in the track groove, and the connecting member 141 is connected to the rotating member 144 .

[0083] In the embodiment of the present application, the rotating member 144 can be an elastic rotating member 144, which has good adaptability and smooth movement, and 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, and the connecting member 141 is rotatably connected to the rotating member 144 at the upper end away from the test turntable 110, and the rotating member 144 is placed in the track groove, and the connecting member 141 is connected to the test component 120 at the lower end close to the test component 120.

[0084] In the embodiment of the present application, the rotating member 144 may be a roller, a roller, a ball, etc., which is not limited in the embodiment of the present application. 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.

[0085] In the embodiment of the present application, the track groove can be limited on one side, that is, one side of the rotating member 144 along the preset direction X contacts the inner wall of the track groove 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 can also be limited on both sides, that is, the rotating member 144 contacts the opposite inner walls of the track groove along both sides of the preset direction.

[0086] In addition, a flange may be provided at the opening of the track groove to reduce the size of the opening, thereby restricting the rotating member 144 within the track groove and reducing the possibility of the rotating member 144 escaping from the track groove.

[0087] According to the technical solution of the embodiment 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.

[0088] In order to facilitate the sliding connection of the connecting member 141, refer to Figure 1 , Figure 7 and Figure 8 In some possible embodiments of the present application, the test turret 100 also includes a support member 150, which is disposed between the track member 142 and the test turntable 110 and is fixed relative to the turret shaft 130, and the connecting member 141 is slidably connected to the outer peripheral side of the support member 150.

[0089] In the embodiment of the present application, the support member 150 and the turret shaft 130 are relatively fixed, specifically, the two are directly or indirectly fixedly connected and can be relatively still, that is, the support member 150 can move synchronously with the turret shaft 130.

[0090] In the embodiment of the present application, the support member 150 can 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 threaded connection, clamping connection, fastener connection, etc. For example, the support member 150 is locked to the turret shaft 130 by multiple fasteners, and the multiple fasteners are evenly arranged around the turret shaft 130 to provide a stable connection and facilitate disassembly and maintenance.

[0091] In the embodiment 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. For example, the radial dimension of the track member 142 is smaller than the radial dimension of the test turntable 110, and the radial dimension of the support member 150 is smaller than the radial dimension of the track member 142, so that the connection member 141 connects the track member 142 and the support member 150 respectively.

[0092] In an embodiment of the present application, a slide groove can be set on the support member 150, and the connecting member 141 is slidably connected in the slide groove, or a guide member and a sliding member assembly are set 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 component 120 along the preset direction X.

[0093] The technical solution of the embodiment of the present application is to set a support member 150, and the support member 150 is used for the sliding connection of the connecting member 141. Since the support member 150 has a larger 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 component 120.

[0094] In order to balance weight reduction and support stability, refer to Figure 7 , Figure 8 and Fig. 9 In some possible embodiments of the present application, 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. The support sleeve 152 is sleeved on the outer peripheral side of the support plate 151. The connecting member 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.

[0095] In the embodiment of the present application, the movable connection between the connecting member 141 and the supporting 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.

[0096] In the embodiment of the present application, the support disc 151 and the support sleeve 152 can be connected by means of clamping, bonding, welding, etc. For example, the support disc 151 and the support sleeve 152 are integrally formed. The size of the support sleeve 152 along the preset direction X is larger than the size of the support disc 151 along the preset direction X, so that the axial cross-section of the support member 150 is an "H"-shaped structure, which has both high structural strength and a large supportable surface.

[0097] In the embodiment of the present application, the support plate 151 is fixed to the turret shaft 130 by 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 trajectory of the support cup 600, the connecting member 141 can be set parallel to the preset direction X and stably supported by the support sleeve 152.

[0098] According to the technical solution of the embodiment of the present application, 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 dimension to facilitate the stable connection of the connector 141, and the axial dimension of the support plate 151 is smaller, which is also conducive to weight reduction.

[0099] In order to stably guide the movement of the connecting member 141, refer to Figure 3 , Figure 4 and Figure 7 In some possible embodiments of the present application, the test turret 100 also includes a guide assembly 160, the guide assembly 160 includes a guide member 161 and a sliding member 162, the guide member 161 is connected to the outer peripheral side of the support member 150, the sliding member 162 is connected to the guide member 161 and moves along the guide member 161, the connecting member 141 is connected to the sliding member 162, and the support sleeve 152 extends to both ends of the guide member 161 along the movement direction of the sliding member 162.

[0100] In the embodiment of the present application, the connection between the sliding member 162 and the guide member 161 can be that the guide member 161 is provided with a slide groove, and a part of the sliding member 162 extends into the slide groove to slide, or the sliding member 162 is sleeved on the outer side of the guide member 161 to slide. For example, the guide member 161 is provided with slide grooves on both sides along the circumference of the support member 150, and the slide grooves extend along the preset direction X. The sliding member 162 is sleeved on the outer side of the guide member 161, and the sliding member 162 has two sliding parts, and the two sliding parts extend into the two slide grooves respectively, so as to realize the sliding connection between the two, and have better guiding accuracy and connection stability.

[0101] In the embodiment of the present application, the sliding member 162 moves along the guiding member 161 , and the extending direction of the guiding member 161 can be set parallel to the preset direction X, and the sliding member 162 slides parallel to the preset direction X relative to the guiding member 161 .

[0102] In the embodiment of the present application, the guide member 161 can be fixed to the outer peripheral side of the support sleeve 152 by bonding, clamping, welding, fastener connection, etc., and the guide member 161 and the support sleeve 152 are similar or equal in size along the preset direction X, so that the two have sufficient connection area, and the support sleeve 152 provides stable support for the guide member 161. In one example, a clamping groove 153 is opened on the support sleeve 152, and the guide member 161 is clamped in the clamping groove 153.

[0103] The technical solution of the embodiment of the present application is to set up 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, and the connecting member 141 is slidably connected to the guide member 161 through the sliding member 162, and under the guidance of the guide component 160, it can move smoothly along the preset direction X.

[0104] In order to facilitate the disassembly and maintenance of the test turret 100, refer to Figure 7 , Figure 8 and Fig. 9 In some possible embodiments of the present application, 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 locking portions 171 that can move relative to each other, and is used to lock and fix the connecting member 141 .

[0105] In an embodiment of the present application, the locking component 170 can be fixedly connected to the sliding member 162, or can be movably connected to the sliding member 162. For example, the locking component 170 is fixedly connected to the sliding member 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.

[0106] In the embodiment of the present application, the locking assembly 170 may include two or more locking parts 171, and a clamping space 172 is formed between the locking parts 171. Different locking parts 171 may be independently provided 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, and the locking parts 171 are made of elastic material to move relative to each other. A cylindrical clamping space 172 is formed between the two locking parts 171 to match the connecting member 141, and the connecting member 141 is clamped in the clamping space 172.

[0107] On this basis, the two locking parts 171 can be fixed by clamping or fastening, so as to clamp and lock the connecting member 141. For example, the two locking parts 171 are provided with connecting holes at one end away from each other, and when the locking parts 171 are close to each other to clamp the connecting member 141, the fastener passes through the connecting holes of the two locking parts 171 to fix the two locking parts 171 relatively.

[0108] The technical solution of the embodiment of the present application is to set a locking component 170, and the locking component 170 locks and fixes the connecting member 141 through the locking part 171, so as to facilitate the disassembly and assembly of the connecting member 141 relative to the guide component 160, so as to facilitate the maintenance of the test component 120, the test turntable 110, etc.

[0109] In order to improve the test efficiency, refer to Figure 2 and Figure 3 In some possible embodiments of the present application, the test turntable 110 includes a receiving slot 111 for receiving the support cup 600 , there are at least two receiving slots 111 , and at least some of the receiving slots 111 are correspondingly provided with the test assembly 120 .

The support cup 600 enters the receiving groove 111 and is surrounded by the enclosure portion and the inner wall of the receiving groove 111 to move along with the rotation of the turntable portion.

[0111] In the embodiment of the present application, the enclosure is provided with an opening corresponding to the feed side or the discharge side of the test turret 100 , so that the support cup 600 can enter the test turntable 110 from the opening on the feed side and leave the test turntable 110 from the opening on the discharge side.

[0112] In the embodiment of the present application, the plurality of receiving grooves 111 may be distributed at equal intervals along the circumference of the test turntable 110 , so as to facilitate the force uniformity of the test turret 100 and the uniform speed transportation of the support cup 600 .

[0113] In the embodiment of the present application, the receiving slots 111 on the turntable portion can be used to receive the cup 600 or partially receive the cup 600 according to design requirements. The position of the receiving slot 111 for receiving the cup 600 corresponds to the position of the testing component 120, which can test the battery cell 700 in the receiving slot 111.

[0114] To improve the test efficiency, in some embodiments, each of the receiving slots 111 for receiving the cup 600 is provided with a corresponding test assembly 120. It is understandable that when there are at least two test assemblies 120, at least two connectors 141 are provided corresponding to the test assemblies 120.

[0116] In order to facilitate the electrical connection of the test assembly 120, refer to Figure 1 and Fig.12 In some possible embodiments of the present application, the testing device further includes a power transmission mechanism 400, which includes a first ring body 410, a second ring body 420 and a conductive wire bundle. The first ring body 410 and the second ring body 420 rotate relative to each other and are electrically connected. The second ring body 420 and the test turntable 110 are relatively fixed, and the conductive wire bundle is connected between the second ring body 420 and the test component 120.

[0117] In the embodiment of the present application, the second ring body 420 is relatively fixed to the test turntable 110, specifically, the axes of the two overlap, and the second ring body 420 is connected to the test turntable 110 by means of snap-on, bonding, welding, interference fit, etc. The second ring body 420 can move synchronously with the test turntable 110.

[0118] In the embodiment of the present application, the power transmission mechanism 400 may 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 test device, and the first ring body 410 is connected to the power supply device, the test host, etc. through a harness. The second ring body 420 is sleeved on the outer peripheral side of the first ring body 410, and the first ring body 410 rotates coaxially with the test turntable 110. The test assembly 120 is connected to the second ring body 420 through a conductive harness, and then electrically connected to the power supply device, the test host, etc.

[0119] In the embodiment of the present application, the first ring body 410 and the second ring body 420 may be electrically connected in a single path or in multiple paths. For example, the first ring body 410 includes at least two conductive slots insulated at intervals along a preset direction X, and the second ring body 420 includes at least two conductive parts insulated at intervals along a preset direction X. The at least two conductive parts slide in the at least two conductive slots in a one-to-one correspondence to form at least two electrical connections, and each conductive part is connected to a conductive wire bundle. It can be understood that the number of paths of electrical connection in the power transmission mechanism 400 corresponds to the number of test components 120.

[0120] In the embodiment of the present application, the power transmission mechanism 400 can be arranged between the support member 150 and the test turntable 110, or between the support member 150 and the track member 142. In one example, the test turntable 110 is arranged on a side of the track member 142 away from the test turntable 110.

[0121] In some possible embodiments, the power transmission component may not be provided, and a wireless connection may be used to establish an electrical connection between the test probe 121 and the test host and the power supply device, wherein the wireless connection may be electromagnetic power transmission, Bluetooth, star flash, wireless network, etc.

[0122] The technical solution of the embodiment of the present application is to set up a power transmission mechanism 400, which includes a first ring body 410 and a second ring body 420 that are electrically connected. The second ring body 420 is connected to the test component 120 through a conductive wire bundle and can rotate synchronously to avoid the guide wire bundle from being entangled during rotation, thereby optimizing the electrical connection method of the test component 120.

[0123] To facilitate the connection of the test probe 121, refer to Figure 4 , Fig.10 and Fig.11 In some possible embodiments of the present application, the test assembly 120 includes a test probe 121 and an adapter 122, the adapter 122 has a set extension direction, the size of the adapter 122 along the extension direction is greater than the size of the adapter 122 along the remaining directions, and the two ends of the adapter 122 along its extension direction are respectively connected to the test probe 121 and the test turntable 110.

[0124] In the embodiment of the present application, the extension direction of the adapter 122 is its maximum dimension. For example, if the adapter 122 is a rod-shaped structure, the extension direction is its axial direction; for another example, if the adapter 122 is a plate-shaped structure or a block-shaped structure, the extension direction is its length direction.

[0125] In the embodiment of the present application, the adapter 122 may be a rectangular plate-shaped structure, one end of the adapter 122 is connected to the lifting assembly 140, for example, one end of the adapter 122 along the length direction is fixedly connected to the lower end of the connector 141, and the other end of the adapter 122 along the length direction is used to install the test probe 121. The adapter 122 and the connector 141 may be bonded, welded, or clamped, for example, an assembly hole 123 is provided on the adapter 122, and the end of the connector 141 extends into the assembly hole 123 to achieve connection.

[0126] 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, which is a through hole, and the test probe 121 is passed through the fixing hole 124, which can provide a stable support and limit for the test probe 121, and also facilitate the test probe 121 to connect to the power transmission mechanism 400 through the conductive wire harness.

[0127] In addition, a protrusion 125 is provided at the portion of the adapter 122 connected to the test probe 121 , thereby increasing the radial dimension of the fixing hole 124 , thereby increasing the connection area between the test probe 121 and the adapter 122 , and improving the stability of the test probe 121 .

[0128] The technical solution of the embodiment of the present application is to provide an adapter 122 , and the test probe 121 is connected to one end of the adapter 122 , which is not easy to interfere with other components of the test turret 100 , thereby facilitating the connection of the test probe 121 .

[0129] In order to make the structure of the test turret 100 more compact, refer to Fig.12 In some possible embodiments of the present application, the test turntable 110 is set with a diameter direction toward the adapter 122, and the extension direction of the adapter 122 is set at an angle to the corresponding diameter direction.

[0130] In the embodiment of the present application, the test turntable 110 can be a disc structure, and the test turntable 110 has multiple diameter directions perpendicular to its axial direction. It can be understood that the multiple diameter directions are different; along the axial projection of the test turntable 110, part of the diameter direction passes through the projection of the adapter 122, and the extension direction of the adapter 122 is set at an acute angle, a right angle or an obtuse angle to the corresponding diameter direction. In other words, the extension direction of the adapter 122 is not parallel to the corresponding diameter direction.

[0131] In the embodiment of the present application, 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 can be set at an acute angle or an obtuse angle with the upper surface.

The length direction of the adapter 122 can be set along the radial or circumferential direction of the test turntable 110, or, it can be set along the remaining directions in the radial plane of the test turntable.

In addition, the test probe 121 can be one, two, or more than two. The two test probes 121 can be arranged along the radial direction of the test turntable 110, or along the circumferential direction of the test turntable 110. The two or more test probes 121 can be arranged in a triangular, circular, square, etc. For example, the two test probes 121 are spaced apart along the length direction of the adapter 122.

[0134] According to 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 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, so that the size of the connecting member 141 can be set smaller, thereby making the structure of the test turret 100 more compact.

Depending on the process sequence, the production equipment 800 has multiple possible forms.

[0144] In the embodiments of the present application, the transfer equipment has many possible forms. For example, the transfer equipment is a conveyor belt, which has a simple structure and high transportation efficiency. For another example, the transfer equipment is an arm-type robot, which can perform more complex operations.

[0145] In the technical solution of the embodiment of the present application, the battery withstand voltage test system includes the above-mentioned test device, and the test component 120 is connected to the test turntable 110 and rotates synchronously with the test turntable 110, that is, the test component 120 moves synchronously with the support cup 600 and the battery cell 700 on the test turntable 110, and the test component 120 and the battery cell 700 can remain relatively still. While the test turntable 110 transports the battery, the test component 120 can test the battery cell 700. The test process does not need to pause the support cup 600 and the battery cell 700, thereby ensuring the continuity of the battery cell 700 transportation process, and the transportation and testing are carried out simultaneously, which can save testing time and optimize the production rhythm.
