Description

Technical Field

[0001] The present application relates to the technical field of lithium battery detection, and in particular to a lithium battery detection device. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. The internal resistance, battery capacity, and battery cycle life of lithium batteries are important indicators for measuring the health status of lithium batteries. Therefore, lithium battery manufacturers need to test lithium batteries before they leave the factory. Because lithium batteries are expensive, have high energy density, poor safety, and are prone to spontaneous combustion, it is particularly important to strengthen the protective fixing effect of lithium batteries and improve the detection efficiency of lithium batteries during the testing of lithium batteries.

[0003] In the related art, the lithium battery testing device uses a conveying device to transport a large number of lithium batteries, which are then taken away by operators for testing. During the transportation process, lithium batteries are prone to fall and cause damage and spontaneous combustion, which in turn brings economic losses and safety risks. In addition, the operators take the batteries away for testing, resulting in low lithium battery testing efficiency and high labor costs. Summary of the invention

[0004] The present application provides a lithium battery detection device, which is used to solve the problems of unstable lithium battery transportation and low detection efficiency in related technologies.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] The present application provides a lithium battery detection device for conveying and detecting lithium batteries, and the lithium battery detection device includes a frame, a conveying mechanism, a clamping assembly, a protective assembly and a detection mechanism. The conveying mechanism is fixed on the frame, and the conveying mechanism includes a conveyor belt, and the conveyor belt is used to convey the lithium battery. The clamping assembly is fixed on the conveyor belt, and the clamping assembly is used to clamp the lithium battery in the horizontal direction, and at least one electrode of the lithium battery is located on the side of the clamping assembly close to the frame. The protective assembly is arranged on the side of the clamping assembly close to the frame and contacts the lithium battery. In this case, when the operator clamps the lithium battery horizontally in the clamping assembly, the protective assembly contacts the lithium battery to prevent the lithium battery from falling off the clamping assembly, thereby ensuring that the lithium battery is smoothly conveyed during the operation of the conveying mechanism and strengthening the protection of the lithium battery.

[0007] In some embodiments, the detection mechanism is disposed on the frame, and the detection mechanism includes a detection electrode, and the detection mechanism can push the protective component toward the direction close to the protective component so that the detection electrode contacts the electrode of the lithium battery. In this case, when the clamping component clamps the lithium battery and runs with the conveyor belt to the detection position, the detection mechanism pushes the protective component toward the direction close to the protective component so that the electrode of the lithium battery is exposed, and then the detection electrode contacts the electrode of the lithium battery to realize the detection of the lithium battery. In this process, fully automated detection of lithium batteries is realized, the detection efficiency of lithium batteries is improved and labor costs are reduced.

[0008] In some embodiments, the protective assembly includes a fixed plate and a protective plate. The fixed plate is fixedly connected to the clamping assembly. The protective plate is disposed on a side of the fixed plate close to the detection mechanism. The protective plate is slidably connected to the fixed plate and can move toward or away from the fixed plate. In this case, when the protective plate is away from the fixed plate, the protective plate contacts the lithium battery to achieve smooth transportation of the lithium battery; when the protective plate is close to the fixed plate, the electrode of the lithium battery contacts the detection electrode to achieve automatic detection of the lithium battery.

[0009] In some embodiments, a first sliding cavity is provided at the end of the protective plate close to the fixed plate, and the first sliding cavity has a first opening on the side facing the fixed plate, and the area of ​​the first opening is smaller than the area of ​​the cross section of the first sliding cavity; the protective assembly also includes a guide rod and a first elastic recovery member. The guide rod includes a guide portion and a limit portion, one end of the guide portion is connected to the fixed plate, and the other end passes through the first opening and extends into the first sliding cavity, and the area of ​​the limit portion is larger than the area of ​​the first opening. The first elastic recovery member is arranged in the first sliding cavity, and one end of the elastic recovery member is fixedly connected to the limit portion, and the other end is fixedly connected to the protective plate. Based on the above structure, when the protective plate is pushed to move in a direction close to the fixed plate, the guide portion and the limit portion of the guide rod move in the first sliding cavity, and the first elastic recovery member generates an elastic recovery force due to the extrusion of the limit portion and the protective plate. When the protective plate is released, the elastic recovery force pushes the protective plate to move in a direction away from the fixed plate, realizing the telescopic function of the protective plate, and then realizing the protective function of the protective plate to the lithium battery.

[0010] In some embodiments, the detection mechanism further includes a bearing body, a pressure plate and a first driving assembly. The pressure plate is connected to the bearing body, and the pressure plate is provided with a detection via hole, and the detection electrode is arranged in the detection via hole. The first driving assembly is connected to the bearing body, and the first driving assembly is used to drive the bearing body to drive the pressure plate to move in the horizontal direction, so that the pressure plate contacts the protective plate, and then pushes the protective plate to move toward the fixed plate.

[0011] In some embodiments, the bearing body includes a connecting arm and a housing, and a second slide groove is provided on the housing, and the second slide groove extends in a vertical direction. The detection mechanism also includes a second drive assembly, which is arranged in the housing and connected to the pressure plate, and the second drive assembly is used to drive the pressure plate to move in a vertical direction along the second slide groove. In this way, the detection of lithium batteries of different sizes can be realized, and the adaptability of the lithium battery detection device can be improved.

[0012] In some embodiments, the clamping assembly includes a fixing member, two clamping members, a transmission assembly and an adjustment rod. The fixing member is fixed to the conveyor belt. The two clamping members are arranged on the side of the fixing member away from the conveyor belt, and the two clamping members are used to clamp the lithium battery in the horizontal direction. The transmission assembly is connected to the clamping member. The adjustment rod is connected to the transmission assembly, and pushing the adjustment rod can cause the transmission assembly to drive the clamping members to move in a direction away from each other. When the two clamping members move to the final position, the lithium battery can be removed from the two clamping members.

[0013] In some embodiments, the transmission assembly includes a first rotating shaft, a gear and two racks. The first rotating shaft is rotatably connected to the fixed member. The gear is fixedly connected to the first rotating shaft. The two racks are respectively connected to the two clamping members and mesh with the gears. The extension direction of the racks is the same as the extension direction of the adjustment rod, and one of the racks is connected to the adjustment rod. In this way, when the adjustment rod is pushed, the adjustment rod drives a rack to move, and then drives the gear to rotate, so that the two racks drive the two clamping members to move in a moving away direction, and the two clamping members are in an open state; similarly, when the two racks move in a moving approaching direction, the two clamping members move in a moving approaching direction, and the two clamping members are in a clamping state, so that the lithium battery can be clamped in the clamping space formed by the two clamping members.

[0014] In some embodiments, the transmission assembly further includes a second elastic recovery member, one end of the second elastic recovery member is connected to the gear and / or the first rotating shaft, and the other end is connected to the fixing member. When the second elastic recovery member is in a natural state, the maximum distance between the two clamping members is less than the minimum radial dimension of the lithium battery. The elastic recovery force of the second elastic recovery member drives the gear to rotate, thereby driving the two clamping members to move, thereby realizing the opening and clamping functions of the two clamping members.

[0015] In some embodiments, the fixing member has a first accommodating cavity, the transmission assembly is located in the first accommodating cavity, and a first slider is provided on the side of the rack away from the gear; the fixing member is provided with a first slide rail, the first slide rail extends along the extension direction of the adjusting rod, the first slider is located in the first slide rail, and can slide along the first slide rail to achieve a guiding effect on the moving direction of the two racks.

[0016] In some embodiments, the conveying mechanism further includes a driving motor, a first transmission member, a second transmission member, a driving wheel and a driven wheel. The driving motor is connected to the frame. The first transmission member includes a connecting portion and a toggle portion, and the connecting portion is connected to the output shaft of the driving motor. The second transmission member is rotatably connected to the frame; the second transmission member is provided with a plurality of grooves. The driving wheel is fixedly connected to the second transmission member; the driving motor drives the first transmission member to rotate, so that the toggle portion cooperates with the groove, and the second transmission member is toggled to drive the driving wheel to rotate intermittently. The driven wheel is connected to the driving wheel through a conveyor belt. In this case, the driving wheel drives the driven wheel and the clamping assembly fixed to the conveyor belt to rotate intermittently through the conveyor belt, so that after one lithium battery is detected, the next lithium battery is transported to the detection position, thereby realizing that the lithium batteries are sequentially transported to the detection position in a feeding motion, thereby ensuring the detection time of the lithium batteries.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] Figure 1 A schematic diagram of the structure of a lithium battery detection device provided in an embodiment of the present application; Figure 2 A schematic structural diagram of a lithium battery detection device provided in an embodiment of the present application without the conveying mechanism, the clamping assembly and the protective assembly.

[0032] The present application embodiment provides a lithium battery detection device 100 for transporting and detecting lithium batteries. For example, the lithium battery may be a cylindrical lithium battery. Figure 1 As shown, the lithium battery testing device 100 includes a frame 10 , a conveying mechanism 20 , a clamping assembly 30 , a protection assembly 40 and a testing mechanism 50 .

[0033] Among them, Figure 1 As shown, the conveying mechanism 20 is fixed on the frame 10, and the conveying mechanism 20 includes a conveyor belt 21, and the conveyor belt 21 is used to convey lithium batteries. The clamping assembly 30 is fixed on the conveyor belt 21, and the clamping assembly 30 is used to clamp the lithium battery in the horizontal direction, and at least one electrode of the lithium battery is located on the side of the clamping assembly 30 close to the frame 10. The protective assembly 40 is arranged on the side of the clamping assembly 30 close to the frame 10, and is in contact with the lithium battery. In this case, when the operator clamps the lithium battery horizontally in the clamping assembly 30, the protective assembly 40 is in contact with the lithium battery to prevent the lithium battery from falling off the clamping assembly 30, ensuring that the lithium battery is smoothly transported during the operation of the conveying mechanism 20, and strengthening the protection of the lithium battery.

[0034] In addition, if Figure 1 and Figure 2 As shown, the detection mechanism 50 is arranged on the frame 10, and the detection mechanism 50 includes a detection electrode 51. The detection mechanism 50 can push the protective component 40 in the direction close to the protective component 40 so that the detection electrode 51 contacts the electrode of the lithium battery. In this case, when the clamping component 30 clamps the lithium battery and runs with the conveyor belt 21 to the detection position, the detection mechanism 50 pushes the protective component 40 in the direction close to the protective component 40 so that the electrode of the lithium battery is exposed, and then the detection electrode 51 contacts the electrode of the lithium battery to realize the detection of the lithium battery. In this process, the fully automated detection of the lithium battery is realized, the detection efficiency of the lithium battery is improved and the labor cost is reduced.

[0035] It should be noted that the moving direction of the detection mechanism 50 is not consistent with the conveying direction of the conveyor belt 21. For example, the moving direction of the detection mechanism 50 is perpendicular to the conveying direction of the conveyor belt 21.

[0036] In some examples, such as Figure 1 As shown, the frame 10 includes a workbench 11 and a support leg 12. The support leg 12 is used to support the workbench 11, ensure the height of the lithium battery detection device, and prevent the surface of the workbench 11 from being corroded by corrosive substances. Among them, a storage drawer 13 can be provided on the side below the workbench 11 close to the detection mechanism 50, for example, for storing maintenance tools or other tools.

[0037] Figure 3 A schematic diagram of the structure of a protective component provided in an embodiment of the present application.

[0038] In some embodiments, in combination Figure 1 and Figure 3 , the protection assembly 40 includes a fixed plate 41 and a protection plate 42. The fixed plate 41 is fixedly connected to the clamping assembly 30, and the protection plate 42 is arranged on the side of the fixed plate 41 close to the detection mechanism 50. The protection plate 42 is slidably connected to the fixed plate 41 and can move in a direction close to or away from the fixed plate 41. In this case, when the protection plate 42 is away from the fixed plate 41, the protection plate 42 contacts the lithium battery to achieve smooth transportation of the lithium battery; when the protection plate 42 is close to the fixed plate 41, the electrode of the lithium battery contacts the detection electrode 51 to achieve automatic detection of the lithium battery.

[0039] In some embodiments, Figure 3As shown, a first sliding cavity 43 is provided at the end of the protective plate 42 close to the fixed plate 41, and a first opening 44 is provided on the side of the first sliding cavity 43 facing the fixed plate 41, and the area of ​​the first opening 44 is smaller than the area of ​​the cross section of the first sliding cavity 43. The protective assembly 40 also includes a guide rod 45 and a first elastic recovery member 46. The guide rod 45 includes a guide portion 451 and a limiting portion 452. One end of the guide portion 451 is connected to the fixed plate 41, and the other end passes through the first opening 44 and extends into the first sliding cavity 43, and the area of ​​the limiting portion 452 is larger than the area of ​​the first opening 44. The first elastic recovery member 46 is arranged in the first sliding cavity 43, and one end of the first elastic recovery member 46 is fixedly connected to the limiting portion 452, and the other end is fixedly connected to the protective plate 42. Based on the above structure, when the protective plate 42 is pushed to move toward the fixed plate 41, the guide portion 451 and the limiting portion 452 of the guide rod 45 move in the first sliding cavity 43, and the first elastic restoring member 46 generates elastic restoring force due to the compression of the limiting portion 452 and the protective plate 42. When the protective plate 42 is released, the elastic restoring force pushes the protective plate 42 to move away from the fixed plate 41, thereby realizing the telescopic function of the protective plate 42, and further realizing the protective function of the protective plate 42 for the lithium battery.

[0040] Exemplarily, the first elastic restoring member 46 may be a spring to achieve the telescopic function of the protective plate 42 .

[0041] Figure 4 A schematic structural diagram of a protective assembly and a clamping assembly provided in an embodiment of the present application.

[0042] In addition, combined Figure 1 , Figure 3 and Figure 4 , a second slide rail 312 is provided on one side of the clamping assembly 30 close to the protection assembly 40, and the second slide rail 312 extends along the moving direction of the detection mechanism 50. The protection plate 42 is provided with a second slider 47, and the second slider 47 is located in the second slide rail 312 and can slide along the second slide rail 312. It can be understood that when the protection plate 42 moves in the direction of approaching or moving away from the fixed plate 41, one end of the guide portion 451 moves in the first slide cavity 43 through the limiting portion 452, thereby guiding the moving direction of the protection plate 42; the second slider 47 slides along the second slide rail 312 to limit the moving range of the protection plate 42.

[0043] In some embodiments, Figure 1 and Figure 2As shown, the detection mechanism 50 further includes a bearing body 52, a pressing plate 53 and a first driving assembly 54. The pressing plate 53 is connected to the bearing body 52, and the pressing plate 53 is provided with a detection through hole 55, and the detection electrode 51 is arranged in the detection through hole 55. The first driving assembly 54 is connected to the bearing body 52, and drives the bearing body 52 to drive the pressing plate 53 to move in the horizontal direction, so that the pressing plate 53 contacts the protective plate 42, and then pushes the protective plate 42 to move toward the fixing plate 41.

[0044] In some examples, such as Figure 2 As shown, the bearing body 52 includes a connecting arm 521 and a housing 522. The connecting arm 521 may be an L-shaped plate, and when the bearing body 52 moves in the horizontal direction, the L-shaped structure of the connecting arm 521 will not interfere with other structures in the device.

[0045] In some examples, such as Figure 2 As shown, the workbench 11 is further provided with two second installation cavities 15, and the first driving assembly 54 is provided in the second installation cavity 15 and connected to the connecting arm 521. For example, the first driving assembly 54 can be an electric telescopic rod, the output end of which is connected to the connecting arm 521, and drives the bearing body 52 to drive the pressing plate 53 to move in the horizontal direction.

[0046] In addition, if Figure 2 As shown, two limit plates 56 are further provided in the second installation cavity 15 , and the adjacent sides of the two limit plates 56 are fixedly connected to the connecting arm 521 , and the distant sides of the two limit plates 56 are slidably connected to the workbench 11 , thereby guiding the moving direction of the supporting body 52 .

[0047] In some embodiments, Figure 2 As shown, the housing 522 is provided with a second slide groove 5221, and the second slide groove 5221 extends in the vertical direction. The detection mechanism 50 also includes a second drive component, which is arranged in the housing 522 and connected to the pressing plate 53, and the second drive component is used to drive the pressing plate 53 to move in the vertical direction along the second slide groove 5221. In this way, the detection of lithium batteries of different sizes can be realized, and the adaptability of the lithium battery detection device 100 is improved.

[0048] In addition, if Figure 2 As shown, the detection mechanism 50 also includes a detection screen 57, and the detection electrode 51 is electrically connected to the detection screen 57. When the pressure plate 53 pushes the protective plate 42 to move toward the fixed plate 41, the detection electrode 51 contacts the electrode of the lithium battery and detects the lithium battery. The detection data will be transmitted to the detection screen 57. This process realizes automatic detection of the lithium battery.

[0049] Figure 5 A schematic diagram of the structure of a fixing member provided in an embodiment of the present application; Figure 6 A schematic structural diagram of a clamping assembly without a fixing member provided in an embodiment of the present application.

[0050] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the clamping assembly 30 includes a fixing member 31, two clamping members 32, a transmission assembly 33 and an adjusting rod 34. The fixing member 31 is fixed on the conveyor belt 21, and the two clamping members 32 are arranged on the side of the fixing member 31 away from the conveyor belt 21. The two clamping members 32 are used to clamp the lithium battery in the horizontal direction. The fixing member 31 has a first accommodating cavity 35, and the transmission assembly 33 is located in the first accommodating cavity 35. The transmission assembly 33 is connected to the clamping member 32, and the adjusting rod 34 is connected to the transmission assembly 33. By pushing the adjusting rod 34, the transmission assembly 33 can drive the clamping member 32 to move in a direction away from each other. When the two clamping members 32 move to the final position, the lithium battery can be removed from the two clamping members 32.

[0051] In some examples, combined Figure 1 , Figure 4 and Figure 5 The fixing member 31 includes a first fixing member 31a and a second fixing member 31b, and the first fixing member 31a and the second fixing member 31b respectively include a fixing member body 31c and two limiting protrusions 31d, the fixing member body 31c is fixedly connected to the conveyor belt 21, and the two limiting protrusions 31d are relatively arranged on the side of the fixing member body 31c away from the conveyor belt 21, and form a first limiting groove 313 with the fixing member body 31c, and two clamping members 32 are arranged in the first limiting groove 313, and can move in a direction of approaching or moving away from each other to achieve clamping and releasing of the lithium battery. Exemplarily, the two surfaces close to the two clamping members 32 can be arc surfaces, which match the surfaces on the peripheral side of the lithium battery. In addition, the two clamping members 32 can be elastomeric materials to avoid damage to the lithium battery during the clamping process of the lithium battery. For example, the two clamping members 32 can be made of hard rubber.

[0052] In addition, combined Figure 4 and Figure 5 , the first fixing member 31a and the second fixing member 31b are both provided with a first sub-cavity 35a and a second sub-cavity 35b around the first limiting groove 313. The first sub-cavity 35a and the second sub-cavity 35b are, for example, N-shaped cavities. The first sub-cavity 35a and the second sub-cavity 35b constitute a first accommodating cavity 35, and the transmission assembly 33 is arranged in the first accommodating cavity 35. One end of the adjusting rod 34 is connected to the transmission assembly 33, and the other end passes through the fixing member 31 from the first accommodating cavity 35 to the surface of the fixing member 31, and is fixedly connected to the adjusting block 341. The adjusting block 341 is, for example, frosted, and when the operator pushes the adjusting block 341, the comfort during the use of the lithium battery detection device 100 can be increased.

[0053] In some embodiments, Figure 6 As shown, the transmission assembly 33 includes a first rotating shaft 331, a gear 332 and two racks 333. The first rotating shaft 331 is rotatably connected to the fixing member 31, the gear 332 is fixedly connected to the first rotating shaft 331, and the two racks 333 are respectively connected to the two clamping members 32 and mesh with the gear 332. The extension direction of the rack 333 is the same as the extension direction of the adjusting rod 34, and one of the racks 333 is connected to the adjusting rod 34. In this way, when the adjusting rod 34 is pushed, the adjusting rod 34 drives one rack 333 to move, and then drives the gear 332 to rotate, so that the two racks 333 drive the two clamping members 32 to move in the away direction, and the two clamping members 32 are in an open state; similarly, when the two racks 333 move in the approaching direction, the two clamping members 32 move in the approaching direction, and the two clamping members 32 are in a clamping state, so that the lithium battery can be clamped in the clamping space formed by the two clamping members 32.

[0054] In some examples, such as Figure 6 As shown, the rack 333 includes a first rack 333a and a second rack 333b. The rack fixedly connected to the adjustment rod 34 is the first rack 333a, and the other rack is the second rack 333b. The first rack 333a and the second rack 333b are fixedly connected to the first push block 334 at the opposite ends, and the second push block 335 is fixedly connected to the other end of the first push block 334. One end of the third push block 336 is fixedly connected to the second push block 335, and one end passes through the fixing member 31 and is connected to the side of the clamping member 32 away from the lithium battery. Among them, the first push block 334, the second push block 335 and the third push block 336 are used to drive the two clamping members 32 to move.

[0055] In some embodiments, in combination Figure 4 and Figure 6 The transmission assembly 33 also includes a second elastic recovery member 337, one end of the second elastic recovery member 337 is connected to the gear 332 and / or the first rotating shaft 331, and the other end is connected to the fixing member 31. The elastic recovery force of the second elastic recovery member 337 drives the gear 332 to rotate, and then drives the two clamping members 32 to move, thereby realizing the opening and clamping functions of the two clamping members 32.

[0056] In some examples, such as Figure 4 and Figure 6As shown, one end of the second elastic recovery member 337 is connected to the gear 332. When the adjustment rod 34 is pushed, the adjustment rod 34 drives a rack 333 to move, and then drives the gear 332 to rotate, so that the two racks 333 drive the two clamping members 32 to move away from each other, and then the lithium battery is placed in the two clamping members 32. At the same time, the rotation of the gear 332 causes one end of the second elastic recovery member 337 to deform and generate an elastic recovery force. When the adjustment rod 34 is released, the elastic recovery force causes the gear 332 to rotate in the opposite direction, and then drives the two racks 333 to drive the two clamping members 32 to move toward the approaching direction, so that the lithium battery is clamped. This process realizes the opening and clamping functions of the two clamping members 32.

[0057] In some examples, such as Figure 4 and Figure 6 As shown, one end of the second elastic recovery member 337 is connected to the first rotating shaft 331. When the adjusting rod 34 is pushed, the adjusting rod 34 drives a rack 333 to move, and then drives the gear 332 to rotate, so that the two racks 333 drive the two clamping members 32 to move in the away direction, and then the lithium battery is placed in the two clamping members 32. At the same time, the rotation of the gear 332 drives the first rotating shaft 331 to rotate, so that one end of the second elastic recovery member 337 is deformed to generate an elastic recovery force. When the adjusting rod 34 is released, the elastic recovery force causes the gear 332 to rotate in the opposite direction, and then drives the two racks 333 to drive the two clamping members 32 to move in the approaching direction, so that the lithium battery is clamped. The effect here is the same as the previous example, and will not be repeated.

[0058] Exemplarily, the second elastic restoring member 337 may be a torsion spring, and the torsion force of the torsion spring causes the gear 332 to rotate, thereby driving the two clamping members 32 to move.

[0059] In addition, in the natural state of the second elastic restoring member 337, the maximum distance between the two clamping members 32 is less than the minimum radial dimension of the lithium battery. It should be noted that the radial dimension refers to the dimension passing through the geometric center of the lithium battery and parallel to the bottom surface of the lithium battery.

[0060] In some embodiments, in combination Figure 4 , Figure 5 and Figure 6 A first slider 338 is provided on the side of the first rack 333a away from the gear 332, and the fixing member 31 is provided with a first slide rail 311, which extends along the extension direction of the adjusting rod 34. The first slider 338 is located in the first slide rail 311 and can slide along the first slide rail 311 to achieve a guiding effect on the moving direction of the two racks 333.

[0061] Figure 7 A partial structural schematic diagram of a conveying mechanism provided in an embodiment of the present application.

[0062] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 The conveying mechanism 20 also includes a driving motor 26, a first transmission member 22, a second transmission member 23, a driving wheel 24 and a driven wheel 25. The driving motor 26 is connected to the frame 10. The first transmission member 22 includes a connecting portion 221 and a toggle portion 222, and the connecting portion 221 is connected to the output shaft of the driving motor 26. The second transmission member 23 is rotatably connected to the frame 10, and the second transmission member 23 is provided with a plurality of grooves 231, and the driving wheel 24 is fixedly connected to the second transmission member 23. The driving motor 26 drives the first transmission member 22 to rotate, so that the toggle portion 222 cooperates with the grooves 231, and the second transmission member 23 is toggled to drive the driving wheel 24 to rotate intermittently. The driven wheel 25 is connected to the driving wheel 24 through the conveyor belt 21, so that the driving wheel 24 drives the driven wheel 25 to rotate synchronously through the conveyor belt 21. In this case, the driving wheel 24 drives the driven wheel 25 and the clamping assembly 30 fixed to the conveyor belt 21 to rotate intermittently through the conveyor belt 21, so that after one lithium battery is tested, the next lithium battery is transported to the testing position, and the lithium batteries are transported to the testing position in turn in a feeding motion, thereby ensuring the testing time of the lithium batteries.

[0063] Exemplary, combined Figure 1 , Figure 2 and Figure 3 The workbench 11 is also provided with two first installation cavities 14, and connecting columns 27 are respectively provided in the two first installation cavities 14, and the connecting columns 27 are rotatably connected to the workbench 11. The driving wheel 24 and the driven wheel 25 are respectively fixedly connected to the connecting columns 27. The driving motor 26, the first transmission member 22, and the connecting column 27 connecting the second transmission member 23 and the driving wheel 24 are arranged in the same first installation cavity 14, and the second transmission member 23 is fixed on the connecting column 27. Based on the above structure, the driving motor 26 drives the first transmission member 22 to rotate, so that the toggle part 222 can cooperate with the groove 231 to toggle the second transmission member 23, and the driving wheel 24 can be driven to rotate intermittently through the connecting column 27 fixedly connected to the second transmission member 23 and the driving wheel 24.
