In the above laminating device 100, the first feeding rack 11 of the conductive film feeding device 1 bears the first feeding mechanism 12, and the first feeding mechanism 12 stably conveys the conductive film along the first direction. The second feeding mechanism 22 of the battery piece feeding device 2 conveys the battery piece along the second direction intersecting the first direction, so as to improve the conveying path precision of the conductive film and the battery piece. The transfer rack 31 is suspended on the top of the conductive film feeding device 1, and the mechanical arm mechanism 32 is movably hung thereon. During work, the mechanical arm can move with high freedom, accurately grasp the battery piece conveyed by the second feeding mechanism 22, and stably transfer the battery piece to the corresponding position of the conductive film along the second direction, so as to accurately laminate each battery piece on the conductive film, and further improve the laminating precision of the battery piece.

[0033] Referring to Figure 1 In optional embodiments, the battery piece feeding device 2 can comprise one, two, three or the like number. Multiple battery piece feeding devices 2 can be distributed outside the conductive film feeding device 1 along the first direction.

[0034] Referring to Figure 3In optional embodiments, the second feeding mechanism 22 of the battery piece feeding device 2 can include one, two, or the like. A plurality of second feeding mechanisms 22 can be arranged on the second feeding rack 21 in the first direction, and the plurality of second feeding mechanisms 22 can simultaneously transport the battery pieces in the second direction, thereby improving the transport efficiency of the battery pieces.

[0035] Referring to Figure 1 In optional embodiments, the mechanical arm mechanism 32 can include one, two, three, four, or the like. Each mechanical arm mechanism 32 corresponds to a second feeding mechanism 22, thereby grasping the battery pieces on the second feeding mechanism 22 and transferring to the conductive film of the conductive film feeding device 1.

[0036] Specifically, the battery piece feeding device 2 includes two, and each battery piece feeding device 2 includes two second feeding mechanisms 22. Two mechanical arm mechanisms 32 correspond to one battery piece feeding device 2, and each mechanical arm mechanism 32 grasps the battery pieces on one second feeding mechanism 22, respectively.

[0037] First, the specific structure of the conductive film feeding device 1 is introduced:

[0038] Referring to Figure 2 In some embodiments, the first feeding mechanism 12 includes a first power component 121 and a first transmission assembly 122 driven to rotate by the first power component 121. The first transmission assembly 122 is rotationally connected to the first feeding rack 11, and the first transmission assembly 122 is used to transport the conductive film in the first direction. The first power component 121 drives the first transmission assembly 122, which can provide stable and continuous power for the conductive film transport. The uniform power output makes the speed of the conductive film stable when it is transported in the first direction. The first transmission assembly 122 is rotationally connected to the first feeding rack 11, and the motion trajectory of the first transmission assembly 122 is relatively fixed, which ensures that the conductive film always moves in the first direction accurately preset, reduces the risk of deviation, and thus improves the overall fitting accuracy.

[0039] In optional embodiments, the first power component 121 can be a stepper motor or a servo motor or a power roller 1211, etc. The first transmission assembly 122 can be a belt assembly or a roller assembly, etc.

[0040] Referring to Figure 2Specifically, the first power component 121 comprises a power roller 1211, and the first transmission assembly 122 comprises a non-power roller 1221 and a roller belt. The power roller 1211 and the non-power roller 1221 are rotationally connected to the first feeding rack 11 in the first direction, and the roller belt is wound on the power roller 1211 and the non-power roller 1221. When the power roller 1211 drives itself to rotate around its axis, the roller belt pulls the non-power roller 1221 to rotate, thereby realizing the conveying of the conductive film in the first direction. Through the transmission of the roller belt, the roller belt can absorb and relieve the impact and vibration in the first transmission assembly 122, reduce the noise and vibration in the transmission process, and reduce the damage of the conductive film in the transmission process.

The second power component 221 drives the second transmission assembly 222, which can provide stable and continuous power for the conveying of the battery piece. The power output is uniform, so that the speed of the battery piece is stable when conveying in the second direction. The second transmission assembly 222 is rotationally connected to the second feeding rack 21, and the motion track of the second transmission assembly 222 is relatively fixed, which ensures that the battery piece always moves in the accurately pre-set second direction, reduces the risk of deviation, and improves the overall fitting accuracy.

[0043] Please refer to Figure 5 In optional embodiments, the second power component 221 can be a stepper motor or a servo motor, etc. The second transmission assembly 222 can be a belt assembly or a roller assembly, etc.

[0044] Please refer to Figure 3 In some embodiments, the battery piece feeding device 2 further comprises a detection mechanism 23 and a correction mechanism 24 arranged on the second feeding rack 21. The correction mechanism 24 is located downstream of the second feeding mechanism 22, and is used for supporting the battery piece output by the second feeding mechanism 22. The detection mechanism 23 is used for identifying the position of the battery piece on the correction mechanism 24 and comparing it with the pre-set position, so that the correction mechanism 24 corrects the battery piece to the pre-set position. During the feeding of the battery piece, deviation of the position of the battery piece may occur due to factors such as vibration of the second feeding mechanism 22 and wear of the components. The detection mechanism 23 can identify the actual position of the battery piece and compare it with the pre-set position, so that the correction mechanism 24 can adjust the position of the battery piece to make it in the pre-set position. When the subsequent battery piece is fitted with the conductive film, the fitting site is accurate, thereby improving the fitting accuracy.

[0045] Referring to Figure 3 In optional embodiments, the correction mechanism 24 and the detection mechanism 23 are provided in plurality, each two detection mechanisms 23 are provided corresponding to one correction mechanism 24. One correction mechanism 24 is provided corresponding to one second feeding mechanism 22. Two detection mechanisms 23 jointly take a picture of the position of one battery piece at a time, and each correction mechanism 24 corrects one battery piece at a time.

[0046] In optional embodiments, the detection mechanism 23 can be a visual detection mechanism or a laser detection mechanism, etc. The visual detection mechanism comprises an image acquisition unit, an image processing unit and a control analysis unit electrically connected, and the control analysis unit is electrically connected with the correction mechanism 24. The image acquisition unit comprises an industrial camera and a light source, etc., and the industrial camera can acquire the actual position image of the battery piece. The image processing unit can process the image and send the image data to the control analysis unit. The control analysis unit compares with the preset position, judges the deviation of the position of the battery piece, and sends the instruction to the correction mechanism 24, so that the correction mechanism 24 corrects the position of the battery piece.

[0047] In optional embodiments, the correction mechanism 24 can be an adsorption type correction mechanism, a clamping type correction mechanism or a push plate type correction mechanism. The adsorption type correction mechanism is to adsorb the battery piece and adjust the battery piece to the preset position. The clamping type correction mechanism is to clamp the battery piece and adjust the battery piece to the preset position. The push plate type correction mechanism is to push the battery piece to the preset position.

[0048] Referring to Figure 4 In some embodiments, the correction mechanism 24 comprises a correction support 241 and a correction driving assembly 242, the correction support 241 is at least partially provided in the correction driving assembly 242, the correction support 241 is used for supporting the battery piece, and the correction driving assembly 242 is provided on the second feeding rack 21, and the correction driving assembly 242 is used for driving the correction support 241 to move the battery piece along the first direction and / or the second direction.

[0049] Referring to Figure 4In some embodiments, the correction support 241 comprises a first support 2411 and a second support 2412, the correction driving assembly 242 comprises a first correction driver 2421 and a second correction driver 2422, the first support 2411 is arranged on the first correction driver 2421, the second support 2412 is arranged on the second correction driver 2422, the first support 2411 and the second support 2412 jointly support the battery sheet, the first correction driver 2421 is used to drive the first support 2411 to move the battery sheet in a first direction, and the second correction driver 2422 is used to drive the second support 2412 to move the battery sheet in a second direction. The first correction driver 2421 and the second correction driver 2422 respectively control the first support 2411 and the second support 2412, and can independently and accurately adjust the position of the battery sheet in the first direction and the second direction. When the detection mechanism 23 identifies that the battery sheet has a positional deviation in a certain direction, the corresponding driver can immediately respond and only fine-tune in the deviation direction, thereby avoiding new errors in other directions that may be introduced by linkage adjustment.

[0050] In optional embodiments, the first correction driver 2421 and the second correction driver 2422 can be linear slide cylinders or electric slide tables.

[0051] Please refer to Figure 5 In some embodiments, the battery sheet feeding device 2 further comprises a pushing frame 25 and a pushing mechanism 26, the pushing frame 25 is arranged on the top of the second feeding mechanism 22, and the pushing mechanism 26 is movably hung on the pushing frame 25. The pushing mechanism 26 is used to move in the second direction to push the battery sheet onto the correction mechanism 24. It can be understood that, since the correction mechanism 24 is located downstream of the second feeding mechanism 22, the second feeding mechanism 22 transports the battery sheet in the second direction, and the battery sheet moves to the correction mechanism 24 under inertia, so it is difficult to accurately control the stopping position of the battery sheet. The pushing mechanism 26 can push the battery sheet in the second direction until the battery sheet is completely located on the correction mechanism 24.

[0052] Please refer to Figure 5 In some embodiments, the pushing mechanism 26 comprises a first moving assembly 261, a first lifting driver 262, and a pushing piece 263.
