[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0041] As the core part of the battery, the battery cell is responsible for storing and releasing electrical energy. During the battery production process, the battery cell needs to be transported so that the battery cell can reach the corresponding workstation for processing, thereby ensuring the smooth progress of each battery production process.

[0042] At present, the carrier for transferring battery cells can only move along the transmission line to transport the battery cells to the corresponding workstations, and then move the battery cells to the processing equipment for processing through the material-retrieving mechanism. After the processing is completed, the battery cells are transferred back to the carrier through the material-retrieving mechanism to facilitate the subsequent processing and transmission of the battery cells. In the battery production process, the battery cells need to undergo multiple loading and unloading operations, and each loading and unloading operation will take a certain amount of time. Such multiple loading and unloading operations will waste time, and more material-retrieving mechanisms will also need to be deployed, increasing production costs.

[0043] The utility model proposes a battery cell conveying carrier. After the battery cell is fixed on the battery cell conveying carrier, it can move along the magnetic levitation conveying line with the battery cell conveying carrier to reach the corresponding processing station. In the production process where the battery cell does not need to be turned around for processing and only needs to be transferred to the corresponding height for processing (such as collecting plate welding), the upward movement of the mounting seat can move the battery cell upward, so that the end of the battery cell can be close to the corresponding processing equipment for easy production and processing, without the need to transfer the battery cell, thus saving the time required for loading and unloading, and helping to improve the battery cell production efficiency. Figures 1 to 3 , which is an embodiment of the battery cell transport carrier proposed in the present invention. Figure 4 This is an embodiment of the magnetic levitation transmission line of the magnetic levitation-based battery core production system proposed in the present invention.

[0044] See also Figure 1 and Figure 2In one embodiment of the utility model, the battery cell transport carrier 100 includes a seat body 1, a supporting structure 2 and a clamping mechanism 3, the seat body 1 includes a fixed seat 11 and a mounting seat 12, the mounting seat 12 is movably mounted on one side of the fixed seat 11; the supporting structure 2 is arranged on the mounting seat 12 to support the battery cell; the clamping mechanism 3 is arranged on the mounting seat 12 and is located above the supporting structure 2 to clamp the battery cell located on the supporting structure 2.

[0045] In the technical solution of the utility model, the battery cell conveying carrier 100 includes a seat body 1, a supporting structure 2 and a clamping mechanism 3, the seat body 1 includes a fixed seat 11 and a mounting seat 12, the mounting seat 12 is movably mounted on one side of the fixed seat 11; the supporting structure 2 is arranged on the mounting seat 12 to support the battery cell placed vertically; the clamping mechanism 3 is arranged on the mounting seat 12 and is located above the supporting structure 2 to clamp the battery cell located on the supporting structure 2. When the battery cell is at the battery cell conveying carrier 100 and the clamping mechanism 3 is in an open state, the supporting structure 2 can support the battery cell so that the battery cell and the clamping mechanism 3 have a relatively determined positional relationship, so that the clamping mechanism 3 can clamp the battery cell. In this way, after the battery cell is fixed on the battery cell conveying carrier 100, it can move along the magnetic levitation conveyor line with the battery cell conveying carrier 100, and then reach the corresponding processing station. In the production process where the battery cell does not need to be turned around for processing and only needs to be transferred to the corresponding height for processing (such as collector plate welding), the upward movement of the mounting seat 12 can move the battery cell upward, so that the end of the battery cell can be close to the corresponding processing equipment for easy production and processing, without the need to transfer the battery cell, saving the time required for loading and unloading, and helping to improve the battery cell production efficiency.

[0046] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The supporting structure 2 includes a sleeve cup 21 for accommodating the battery cell, a support column 21a is arranged in the sleeve cup 21, and the bottom of the battery cell is placed on the support column 21a. When the battery cell is clamped on the clamping mechanism 3, the support column 21a supports the battery cell, and the sleeve cup 21 limits the battery cell so that the battery cell is in a vertical state, so that the clamping mechanism 3 can clamp the battery cell.

[0047] Further, in the embodiments of the present invention, please refer to Figure 1 and Figure 2, the diameter of the support column 21a is smaller than the inner diameter of the sleeve cup 21, and the support column 21a is spaced apart from the side wall of the sleeve cup 21 to form an accommodation gap. In the welding process of the collector plate of the battery cell, when the collector plate at one end of the battery cell is welded, and the pole ear of the collector plate is bent 90° through the collector plate pole ear bending process, the battery cell needs to be turned around to weld the collector plate at the other end of the battery cell. By setting the support column 21a and the side wall of the sleeve cup 21 spaced apart, the accommodation gap is formed between the support column 21a and the side wall of the sleeve cup 21. In this way, the accommodation gap can accommodate the pole ear of the collector plate on the battery cell, so as to meet the needs of the welding process of the collector plate of the battery cell, and is not only suitable for the transportation of battery cell monomers, but also improves the versatility of the battery cell transportation fixture.

[0048] The clamping mechanism 3 is used to limit and clamp the battery core, thereby keeping the battery core in a vertical state to facilitate subsequent processing. Figure 1 and Figure 2 The mounting seat 12 has a setting surface which is away from the fixing seat 11 and extends in the up-down direction, and the setting surface is provided with a connecting plate 121; the clamping mechanism 3 includes a clamping assembly 31 and a clamping driving structure 32, the clamping assembly 31 includes two clamping arms 311, the two clamping arms 311 are arranged on the side of the connecting plate 121 which is away from the mounting seat 12 and extends in the up-down direction, the two clamping arms 311 are movable in the direction of approaching and moving away from each other, so as to be able to approach each other to jointly clamp the battery cell, and move away from each other to release the battery cell; the clamping driving structure 32 is arranged on the mounting seat 12 and is located below the clamping assembly 31, and the clamping driving structure 32 is respectively connected to the two clamping arms 311 to drive the two clamping arms 311 to approach or move away from each other. In this way, when the battery cell is clamped, the clamping drive structure 32 drives the two clamping arms 311 to move simultaneously away from each other to form a battery cell placement space between the two clamping arms 311. When the battery cell is in place, the clamping drive structure 32 drives the two clamping arms 311 to move simultaneously close to each other, thereby clamping the battery cell together.

[0049] Specifically, in the embodiments of the present invention, please refer to Figure 1 and Figure 2The clamping drive structure 32 includes a connecting block 321 and a connecting assembly 322. The connecting block 321 is arranged on the mounting seat 12 and is movably arranged in the up and down directions. The upper end surface of the connecting block 321 is provided with two supporting parts spaced apart in the front and back directions, and a mounting shaft is provided between the two supporting parts; the connecting assembly 322 includes two connecting rods 322a rotatably mounted on the mounting shaft, and one end of the two connecting rods 322a away from the mounting shaft is rotatably connected to the corresponding clamping arm 311, so as to make the two clamping arms 311 approach or move away from each other under the drive of the connecting block 321. Since the two clamping arms 311 are movable in directions approaching and moving away from each other, and one end of each connecting rod 322a is rotatably mounted on the rotating shaft, and the other end is rotatably mounted to the corresponding clamping arm 311, when the connecting block 321 moves upward, the two clamping arms 311 move away from each other under the pushing action of the corresponding connecting rod; when the connecting block 321 moves downward, the two clamping arms 311 move toward each other under the pulling action of the corresponding connecting rod, thereby achieving the clamping and release of the battery cell.

[0050] In the embodiments of the present invention, please refer to Figure 2 The clamping mechanism 3 further includes an elastic traction member 33 connecting the two clamping arms 311, which is used to drive the two clamping arms 311 that are away from each other to move closer to each other. In this way, when the connecting block 321 moves downward, the two clamping arms 311 can quickly move closer to each other under the traction of the corresponding connecting rod and the traction of the elastic traction member 33, so as to achieve rapid clamping of the battery cell, and the two clamping arms 311 have a tendency to move closer to each other under the action of the elastic traction member 33, so that the clamping stability of the clamping assembly 31 is better.

[0051] In the embodiments of the present invention, please refer to Figure 2 Each of the clamping arms 311 is provided with a mounting hole; the clamping mechanism 3 further includes a roller 311a, which is rotatably mounted in the mounting hole along an axis extending in the vertical direction and partially protrudes from the mounting hole to contact the battery cell. In this way, during the clamping and unloading process of the battery cell, the battery cell can be prevented from being bumped, which helps to improve the production quality of the battery cell.

[0052] See also Figure 3 and Figure 4The utility model also proposes a battery cell production system based on magnetic levitation, including a battery cell conveying carrier 100 and a magnetic levitation transmission line 200. The specific structure of the battery cell conveying carrier 100 refers to the above embodiment. The magnetic levitation transmission line 200 includes a magnetic levitation track 201 and a magnetic levitation mover, and the magnetic levitation mover can move along the magnetic levitation track 201; wherein, the fixing seat 11 of the battery cell conveying carrier 100 is connected to the magnetic levitation mover, so that the battery cell conveying carrier 100 can move along the magnetic levitation track 201 driven by the magnetic levitation mover. The battery cell carrier moves along the magnetic levitation track 201 driven by the magnetic levitation mover. In this way, multiple processing devices of the battery cell can be arranged in sequence along the extension direction of the magnetic levitation track 201 according to the sequence of the process, that is, continuous transmission of the battery cell can be realized without storage and transportation, so as to prevent the battery cell from bumping during storage and transportation and improve product quality.

[0053] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The cylindrical battery cell production system further includes a first lifting mechanism 202 disposed on one side of the magnetic suspension track 201, and the first lifting mechanism 202 is used to lift the mounting seat 12 so that the cell on the mounting seat 12 can move upward. In this way, the mounting seat 12 moves upward under the lifting action of the first lifting mechanism 202 to transfer the cell to a corresponding height to meet the processing requirements of the cell at the corresponding processing step (such as collector plate welding), without the need to transfer the cell, saving the time required for loading and unloading, and helping to improve the cell production efficiency.

[0054] In the embodiments of the present invention, please refer to Figure 3 and Figure 4The clamping mechanism 3 includes two clamping arms 311, two connecting rods 322a and a connecting block 321. The two ends of the connecting rod 322a are respectively hinged to the connecting block 321 and the clamping arm 311. The connecting block 321 moves up and down to drive the connecting rod 322a to drive the clamping arm 311 to move, so that the two clamping arms 311 can approach each other to jointly clamp the battery cell, and move away from each other to release the battery cell; the cylindrical battery cell production system also includes a second lifting mechanism 203 arranged corresponding to the magnetic levitation track 201, and the second lifting mechanism 203 is used to lift the connecting block 321 to drive the clamping arm 311 to release the battery cell. Since the battery cell conveying carrier 100 realizes vertical clamping of the battery cells, the battery cells need to be unloaded and re-clamped in some processing steps of the battery cells. For example, in the battery cell collector plate welding processing, after the collector plate welding of the positive or negative terminal of the battery cell is completed, the battery cell needs to be turned around so that the end of the unwelded collector plate is facing the collector plate processing device to facilitate the welding of the collector plate. When the battery cell carrier moves to the second lifting mechanism 203, the second lifting mechanism 203 lifts the connecting block 321 to drive the clamping arm 311 to release the battery cell, thereby turning around and clamping the battery cell. By providing the second lifting mechanism 203, the battery cell conveying carrier 100 can be automatically opened after the battery cell reaches the corresponding process.

[0055] It should be noted that the specific structures of the first lifting mechanism 202 and the second lifting mechanism 203 are not limited, and they may be cylinders, hydraulic cylinders, or other mechanical structures that can achieve a lifting effect.

[0056] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
