[0052] In the embodiment of the present application, by setting the horizontal transport module 210 on the base 10, the clamping mechanism 30 is connected to the horizontal transport module 210, the clamping assembly 310 has a clamping space, and the size of the clamping space can be adjusted by the adjusting member 410 in the adjusting mechanism 40, and then the battery cell 110 can be clamped and fixed by the clamping assembly 310, so that the clamping mechanism 30 moves relative to the horizontal transport module 210 along the first direction X to drive the battery cell 110 to pass through the detection mechanism 50 to realize the detection of the battery cell 110. In this way, during the detection process, the battery cell 110 is clamped and fixed by the clamping assembly 310, which can prevent the battery cell 110 from tilting or falling, thereby improving the stability and safety of the battery cell 110 during the movement process, and the size of the clamping space can be adjusted by the adjusting member 410, which facilitates the installation and removal of the battery cell 110.

[0055] Among them, the adjustment member 410 can be driven by a motor, a cylinder, a hydraulic cylinder or the like. Of course, other types of driving members can also be selected and can be flexibly selected according to actual conditions. The embodiment of the present application does not limit this.

[0056] Alternatively, if Figure 7 and Figure 8 As shown, the detection mechanism 50 includes a first movable module 510 and a detection module 520, a first fixed frame 130 is provided on the base 10, the horizontal transport module 210 passes under the first fixed frame 130, the first movable module 510 is installed on the first fixed frame 130, and the detection module 520 is connected to the first movable module 510. The detection module 520 can be driven by the first movable module 510 to move along the second direction Y and the third direction Z relative to the first fixed frame 130.

[0057] In a specific application, when the clamping mechanism 30 carries the battery cell 110 and moves to the bottom of the first fixed frame 130, the second moving module 613 drives the detection module 520 to move so that the detection module 520 is close to the battery cell 110, and then the performance parameters of the battery cell 110 are detected by the detection module 520. The detection module 520 can be connected to the control system, and the control system determines whether the battery cell 110 is qualified according to the performance parameters obtained by the detection. If the battery cell 110 is qualified, the battery cell 110 is continued to be cleaned and other operations are performed. If the battery cell 110 is unqualified, the unqualified battery cell 110 can be taken out from the first conveying mechanism 20.

[0058] In some embodiments, Figure 7 and Figure 8 As shown, the detection module 520 includes a substrate 521, a guide rail 522 and two probe assemblies 523. The battery cell 110 is provided with a pole 111 (see Figure 5 ); the substrate 521 is connected to the first moving module 510, the guide rail 522 is connected to the substrate 521, and the two probe assemblies 523 are slidably connected to the guide rail 522 along the second direction Y.

[0059] Furthermore, a scale line is provided on the base plate 521 near the guide rail 522, an indication arrow is provided on the probe seat 5231, and a T-slot is provided in the base plate 521, a T-nut is placed in the T-slot, and a bolt passes through the indication arrow and is threadedly connected with the T-nut. When in use, the probe seat 5231 can be moved, and the probe 5232 can be adjusted to a preset position according to the indication scale of the indication arrow, and then the indication arrow and the base plate 521 can be fixed by tightening the bolt and the T-nut.

[0060] In a specific application, the relative positions of the two probes 5232 can be determined according to the positions of the positive and negative electrodes in the battery cell 110 to be tested, and the positions of the two probe holders 5231 on the guide rail 522 can be adjusted so that the spacing between the two probes 5232 matches the spacing between the positive and negative electrodes in the battery cell 110.

[0061] Furthermore, when the clamping mechanism 30 carries the battery cell 110 and moves to the bottom of the detection module 520, the first movable module 510 adjusts the position of the detection module 520 as a whole along the third direction Z so that the two probes 5232 respectively contact the positive and negative electrodes on the battery cell 110, and the detection operation of the battery cell 110 can be performed.

[0063] Alternatively, if Figures 3 to 6 As shown, the clamping mechanism 30 also includes a carrier 320, which is connected to the horizontal transport module 210; the clamping assembly 310 includes a limit member 311 and a clamping member 312; the clamping member 312 and the limit member 311 are connected to the carrier 320 along the second direction Y, and the clamping member 312 and the limit member 311 define a clamping space; the adjusting member 410 is used to drive the clamping member 312 to move closer to or away from the limit member 311 along the second direction Y to adjust the size of the clamping space.

[0064] In the embodiment of the present application, the carrier 320 is connected to the horizontal transport module 210, the clamping member 312 and the limit member 311 are both connected to the carrier 320, the clamping member 312 can slide relative to the carrier 320, and then the adjusting member 410 can be used to drive the clamping member 312 to approach or move away from the limit member 311 along the second direction Y, so as to adjust the size of the clamping space formed between the clamping member 312 and the limit member 311, so as to facilitate flexible loading and unloading of the battery cell 110.

[0065] Specifically, the limiting member 311 is connected to the carrier 320, the clamping member 312 is movably connected to the carrier 320, and the clamping member 312 and the limiting member 311 define a clamping space. Among them, a limiting groove is provided in the limiting member 311, and the limiting groove has three groove walls. When the battery cell 110 is placed in the limiting groove, the three groove walls of the limiting groove correspond to the three side surfaces of the battery cell 110 respectively, so as to form a three-sided limit for the battery cell 110. Furthermore, the clamping member 312 is arranged to correspond to the remaining side surface of the battery cell 110, so that the battery cell 110 can be clamped and fixed in an all-round manner through the cooperation of the clamping member 312 and the limiting member 311, and the fixing reliability of the battery cell 110 can be improved.

[0066] Furthermore, the limit member 311 is detachably connected to the carrier 320 so that limit members 311 of different specifications can be configured according to different sizes of the battery cells 110. Then, in actual use, the corresponding limit member 311 can be selected according to the specifications of the battery cells 110 to be tested, and installed on the carrier 320 to better match the fixing requirements of the battery cells 110, thereby improving the applicability of the clamping assembly 310.

[0067] Alternatively, if Figures 4 to 6As shown, the clamping mechanism 30 further includes an adjusting block 330 , which is connected to the clamping member 312 ; and the adjusting member 410 is connected to the adjusting block 330 to drive the clamping member 312 to move.

[0068] In the embodiment of the present application, an adjustment block 330 is provided to be connected to the clamping member 312 so that the adjustment block 330 can drive the clamping member 312 to move relative to the limiting member 311, thereby achieving adjustment of the size of the clamping space formed between the clamping member 312 and the limiting member 311.

[0069] Specifically, an adjustment block 330 is provided in the carrier 320, and the adjustment block 330 is slidably connected to the carrier 320. One end of the adjustment block 330 is connected to the clamping member 312, and the other end of the adjustment block 330 corresponds to the adjustment member 410. The adjustment member 410 can drive the adjustment block 330 to move relative to the carrier 320, and then the adjustment block 330 drives the clamping member 312 to approach or move away from the limiting member 311 to adjust the size of the clamping space between the clamping member 312 and the limiting member 311.

[0070] Optionally, the base 10 also has a third direction Z that is perpendicular to the first direction X and the second direction Y. A guide groove 321 is provided in the carrier 320 and passes through the third direction Z. The adjustment block 330 is located in the guide groove 321, and the adjustment block 330 is connected to one end of the clamping member 312 along the third direction Z.

[0071] In the embodiment of the present application, a guide groove 321 is set in the carrier 320, and the adjustment block 330 is slidably connected in the guide groove 321. The clamping member 312 is connected to the adjustment block 330, and the adjustment block 330 can slide in the guide groove 321 along the second direction Y, thereby driving the clamping member 312 along the second direction Y to approach or move away from the limit member 311.

[0072] In some embodiments, Figure 5 As shown, a plurality of first mounting holes 331 can be provided in the adjustment block 330, and the plurality of first mounting holes 331 are arranged in sequence and spaced apart along the moving direction of the adjustment block 330, and a second mounting hole 3121 penetrating along a third direction Z is provided in the clamping member 312, and the second mounting hole 3121 is positioned and matched with the first mounting hole 331.

[0073] Furthermore, a fastener may be provided, and the fastener is used to pass through the second mounting hole 3121 and the first mounting hole 331 in sequence to install and fix the clamping member 312 and the adjusting block 330. For example, the first mounting hole 331 may be set as a threaded hole, and the fastener may be a bolt. During installation, the bolt is passed through the second mounting hole 3121 and then threadedly connected to the first mounting hole 331 to achieve connection and fixation of the clamping member 312 and the adjusting block 330.

[0074] By setting the first mounting hole 331 in the adjusting block 330 and setting the second mounting hole 3121 in the clamping member 312, the clamping member 312 is mounted and fixed on the adjusting block 330 by using a fastener. In addition, since the adjusting block 330 is provided with a plurality of first mounting holes 331 arranged at intervals, the mounting position of the clamping member 312 in the adjusting block 330 can be flexibly adjusted according to the thickness of the battery cell 110, thereby adjusting the initial spacing between the clamping member 312 and the limiting member 311 to meet the clamping and fixing requirements for battery cells 110 of different sizes.

[0075] In some embodiments, the spacing between two adjacent first mounting holes 331 is equal. By setting the spacing between two adjacent first mounting holes 331 to be equal, the installation position of the clamping member 312 on the adjustment block 330 can be accurately adjusted, thereby facilitating the actual assembly operation.

[0076] Alternatively, if Figures 4 to 6 As shown, the clamping mechanism 30 further includes an elastic member 340 , one end of the elastic member 340 is connected to the carrier 320 , and the other end is connected to the adjustment block 330 . The elastic member 340 is used to enable the clamping member 312 to clamp the battery cell 110 .

[0077] In the embodiment of the present application, an elastic member 340 is arranged in the clamping mechanism 30, so that one end of the elastic member 340 is connected to the carrier 320, and the other end is connected to the adjustment block 330, and then the elastic contraction effect of the elastic member 340 is utilized to provide a pre-tightening force for the adjustment block 330 in the direction of the limit member 311.

[0078] Specifically, Figure 6 As shown, an elastic member 340 is arranged on the carrier 320, and the elastic member 340 can be telescopically deformed along the second direction Y. The telescopic direction of the elastic member 340 is consistent with the sliding direction of the adjustment block 330. The elastic member 340 has a first end and a second end relative to each other, so that the first end is connected to the carrier 320, the second end is connected to the adjustment block 330, and the second end is located on the side of the first end away from the limit member 311.

[0079] Furthermore, a first boss 411 is provided at one end of the adjusting member 410 facing the adjusting block 330, and a second boss 332 is provided at one end of the adjusting block 330 facing the adjusting member 410. When the clamping mechanism 30 moves along the horizontal conveying module 210 to the position of the adjusting member 410 on the base 10, the first boss 411 and the second boss 332 are exactly in correspondence with each other. By controlling the operation of the adjusting member 410, the first boss 411 in the adjusting member 410 can be used to pull the second boss 332 in the second direction Y to move away from the limiting member 311, and then the adjusting member 410 drives the tightening member away from the limiting member 311, so that the tightening member and the limiting member 311 are relatively opened, so as to load the battery cell 110 into the clamping space, or take out the battery cell 110 in the clamping space. At this time, the elastic member 340 is in a stretched state, and the elastic member 340 undergoes elastic deformation to generate a rebound force toward the limiting member 311.

[0080] After the installation of the battery cell 110 is completed, the operation of the adjusting member 410 is controlled so that the first boss 411 in the adjusting member 410 moves along the second direction Y toward the limit member 311 until the first boss 411 is separated from the second boss 332. The elastic member 340 contracts under the action of the rebound force, thereby providing a pre-tightening force toward the limit member 311 for the adjusting block 330, so that the adjusting block 330 drives the clamping member 312 and the limit member 311 to clamp the battery cell 110.

[0081] In this way, the size of the clamping space can be adjusted by the cooperation between the adjusting member 410 and the elastic member 340, so as to facilitate the installation and removal of the battery cell 110. At the same time, the elastic contraction of the elastic member 340 provides a clamping force for the clamping member 312, so as to avoid rigid contact between the clamping member 312 and the battery cell 110, thereby preventing the battery cell 110 from being clamped.

[0082] In addition, after the battery cell 110 is clamped and fixed, the first boss 411 is separated from the second boss 332 , so that the adjustment member 410 and the adjustment block 330 are not in contact with each other, thereby avoiding interference of the adjustment member 410 with the movement of the clamping mechanism 30 .

[0085] Exemplarily, three stations are provided on the base 10 along the first direction X, namely, a loading station for the battery cell 110, a loading station for the qualified battery cell 110, and a unloading station for the unqualified battery cell 110, wherein the loading station for the qualified battery cell 110 is located between the loading station for the battery cell 110 and the unloading station for the unqualified battery cell 110. Furthermore, an adjustment mechanism 40 is provided at each of the three stations, so that the size of the clamping space in the clamping assembly 310 can be adjusted at the corresponding station through the adjustment member 410 in the adjustment mechanism 40, thereby realizing the installation and removal of the battery cell 110.

[0100] Specifically, a plasma cleaning module 621 and a third movable module 622 may be respectively disposed on both sides of the horizontal transport module 210 along the second direction Y, so that the plasma cleaning modules 621 on both sides can be used to clean both sides of the battery cell 110, thereby improving the cleaning efficiency of the battery cell 110.

The pole cleaning mechanism 610 can be arranged on the side of the battery cell cleaning mechanism 620 close to the detection mechanism 50, or it can be arranged on the side of the battery cell cleaning mechanism 620 away from the detection mechanism 50. The specific positions of the two are flexibly set according to the actual structural layout, and the embodiments of the present application are not limited to this.

[0105] Specifically, Figures 13 to 15As shown, the clamp mechanism 70 includes a clamp driving module 710, a fixing plate 720 and two clamp assemblies 730.

The clamping jaw 732 can be driven by the driving member 733 to slide along the first direction X relative to the linear guide rail 740, thereby clamping or opening the two clamping jaws 732 to each other, so as to clamp the cleaned battery cell 110 from the clamping mechanism 30, so as to transport the cleaned qualified battery cell 110 to the second conveying mechanism 120.

[0107] After the qualified battery cell 110 is cleaned, the battery cell 110 is carried by the clamping mechanism 30 and transferred to the bottom of the clamping mechanism 70, and the adjustment member 410 in the adjustment mechanism 40 at the corresponding position is controlled to operate, so as to drive the clamping member 312 and the limit member 311 in the clamping assembly 310 to open relatively. Then, the two clamping jaws 732 in the clamping mechanism 70 clamp the battery cell 110, and the cleaned battery cell 110 is removed from the clamping mechanism 30, and then the clamping mechanism 30 can be used to carry the next battery cell 110 to perform the inspection and cleaning operation.

[0111] Furthermore, when the clamp mechanism 70 is used to clamp the battery cell 110, the clamp driving module 710 drives the clamp mechanism 70 to approach the horizontal transport module 210 along the third direction Z, and when the upper end of the battery cell 110 enters between the two clamps 732, the clamp assembly 730 at least partially contacts the battery cell 110. At this time, if the clamp driving module 710 drives the clamp mechanism 70 to continue to move downward, the fixed plate 720 and the connecting plate 711 will slide relative to each other along the third direction Z and compress the spring 752, and the elastic deformation of the spring 752 plays a buffering role to prevent the clamp assembly 730 from rigidly squeezing the battery cell 110 and causing damage to the battery cell 110.

[0112] Furthermore, a flexible material layer may be provided on the side where the two clamping jaws 732 are close to each other. When the clamping jaws 732 are used to clamp the battery cell 110 , the flexible material layer on the clamping jaws 732 contacts the battery cell 110 , thereby providing buffer protection for the battery cell 110 .

The fourth movable module 810 can be installed on the first fixed frame 130, that is, the scanning mechanism 80 and the detection mechanism 50 share a fixed frame, so that the installation space can be saved. The scanning element 820 is connected to the fourth movable module 810, and the scanning element 820 can be driven to move relative to the first fixed frame 130 by the fourth movable module 810. Furthermore, when the clamping mechanism 30 carries the battery cell 110 and moves to the corresponding position of the scanning mechanism 80, the scanning element 820 is driven by the fourth movable module 810 to approach the battery cell 110, so that the nameplate information on the battery cell 110 can be scanned and identified by the scanning element 820.
