[0036] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0037] Reference Figure 1 The automatic battery welding production line provided in this application includes a welding turntable 100, a welding mechanism, a first conveyor line 400, and a second conveyor line 500.
[0038] The welding turntable 100 is circumferentially spaced with multiple sets of positioning fixtures 300, which can position and fix the received battery cells. The welding mechanism is used to weld the battery cells positioned by the positioning fixtures 300. The welding turntable 100 can rotate cyclically, and under the rotation of the welding turntable 100, each positioning fixture 300 can move to the welding mechanism to weld the battery cell.
[0039] One end of the first conveyor line 400 can transport the battery cell to the positioning fixture 300, and the other end of the first conveyor line 400 can remove the battery cell from the positioning fixture 300. By setting different processing stations at different positions of the first conveyor line 400, the battery cell can be reassembled or inspected, and then transported to the welding turntable 100 for further welding process.
[0040] One end of the second conveyor line 500 can remove the cups on the positioning fixture 300, and the other end of the second conveyor line 500 can transport the cups loaded with materials to the positioning fixture 300.
[0041] The auxiliary material feeding device is used to load auxiliary materials onto the battery cells and can transport the battery cells with the auxiliary materials onto the trays on the second conveyor line 500.
[0042] The auxiliary materials here include negative collector plate, positive collector plate, and cap, etc.
[0043] Specifically, the auxiliary material feeding device includes a negative current collector feeding mechanism, a positive current collector feeding mechanism, and a cap feeding mechanism. During the process of the cup being transported from one end of the second conveyor line 500 to the other end, the negative current collector feeding mechanism assembles the negative current collector onto the battery cell and then transports the battery cell with the negative current collector onto the cup on the second conveyor line 500, as needed; or, the positive current collector feeding mechanism assembles the positive current collector onto the battery cell and then transports the battery cell with the positive current collector onto the cup on the second conveyor line 500; or, the cap feeding mechanism assembles the cap onto the battery cell and then transports the battery cell with the cap onto the cup on the second conveyor line 500.
[0044] It should be noted that the positions of the welding turntables 100 at both ends of the first conveyor line 400 and the two ends of the second conveyor line 500 are different, so that the loading and unloading do not interfere with each other.
[0045] In this embodiment, the number of positioning fixtures 300 is greater than 18 groups. When in use, the positioning fixtures 300 on the welding turntable 100 are divided into at least three parts, each part including at least 6 positioning fixtures 300. Each positioning fixture 300 in each part is used for positive electrode plate welding, negative electrode plate welding, cap penetration welding, pre-spot welding, full welding, and positive electrode post welding of the battery cell. The battery cell positioned on the positioning fixtures 300 is welded by the welding mechanism. The first conveyor line 400 is used for conveying the bare battery cell to other work stations for corresponding operations.
[0046] The second conveyor line 500 can remove the cups that have been unloaded from the positioning fixture 300, load auxiliary materials onto the battery cells through the auxiliary material feeding device, and then transport the battery cells with auxiliary materials to the cups conveyed on the second conveyor line 500. The battery cells with auxiliary materials are then transported back to the positioning fixture 300 through the second conveyor line 500. Different auxiliary materials are loaded through the auxiliary material feeding device, and the battery cells loaded with different auxiliary materials are returned to the welding turntable 100 through the second conveyor line 500 for other welding processes, thus realizing mixed-flow welding production.
[0047] The battery production line of this application can adopt a mixed-flow mode for loading and unloading (each batch has multiple positioning fixtures 300 respectively with battery cells to be welded to the positive electrode plate, battery cells to be welded to the negative electrode plate, battery cells to be welded to the cap through weld, battery cells to be pre-spot welded, battery cells to be fully welded, and battery cells to be welded to the positive electrode post). In this way, even if one of the positioning fixtures 300 has no battery cell material, it will not affect the loading and unloading or welding operations of the other positioning fixtures 300, realizing non-stop welding and effectively improving welding efficiency.
[0048] In some embodiments, such as Figure 1 As shown, a first feeding disc 410 and a second feeding disc 420 are respectively provided at both ends of the first conveyor line 400, which are capable of rotating and feeding. Both the first feeding disc 410 and the second feeding disc 420 rotate around their own center. The outer periphery of the first feeding disc 410 and the second feeding disc 420 are provided with grooves for positioning the battery cells. The groove walls are provided with magnets that can attract the battery cells or cups. The battery cells or cups are fixed in the grooves by the magnets, so that the battery cells or cups on the positioning fixture 300 can be easily and quickly removed, or the battery cells or cups can be released into the positioning fixture 300.
[0049] like Figure 1As shown, the second conveyor line 500 is provided with a third distribution plate 510 and a fourth distribution plate 520 at both ends, which are capable of rotating and feeding. The third distribution plate 510 and the fourth distribution plate 520 rotate around their own center. The outer periphery of the third distribution plate 510 and the fourth distribution plate 520 is provided with grooves for positioning the battery cells. The groove walls are provided with magnets that can attract the battery cells or cups. The battery cells or cups are fixed in the grooves by the magnets, so that the battery cells or cups on the positioning fixture 300 can be easily and quickly removed, or the battery cells or cups can be released into the positioning fixture 300.
[0050] In some embodiments, such as Figure 2 As shown, the negative collector plate feeding mechanism, the positive collector plate feeding mechanism, and the cap feeding mechanism all include a feeding robot 530. The side of the second conveyor line 500 is provided with a first tray 502 for placing the negative collector plate, a second tray 503 for placing the positive collector plate, and a third tray 504 for placing the cap. The feeding robot 530 assembles the relevant auxiliary materials onto the battery cells and then moves the battery cells with the assembled auxiliary materials to the support cup of the second conveyor line 500. The feeding robot 530 includes a linear motion module and grippers for holding the materials.
[0051] In some embodiments, the second conveyor line 500 is also provided with a detection device 501 for identifying the identification code of the battery cell.
[0052] In some embodiments, the first conveyor line 400 includes a second feeding module for feeding bare battery cells onto the first conveyor line 400.
[0053] Specifically, such as Figure 3 As shown, the second feeding module includes a material rack, a picking robot 432, a third conveyor line, and a handling robot. The third conveyor line is sequentially equipped with a cell scanning mechanism 433, a cell polarity detection mechanism, a cell rounding detection mechanism 434, a cell flattening mechanism 435, a cell dust removal mechanism 436, a cell short circuit detection mechanism 437, and a length detection mechanism 438. The mechanisms on the third conveyor line described above are all existing technologies and will not be elaborated upon further here.
[0054] When the second module is loaded, the bare battery cells are taken out from the material rack by the picking robot 432 and sent to the third conveyor line. The bare battery cells are then subjected to a series of tests by the relevant mechanisms on the third conveyor line. If there are no problems, the qualified bare battery cells are transported to the first conveyor line 400 by the handling robot, while the unqualified battery cells are moved to the recycling rack for storage.
[0055] In some embodiments, the first conveyor line 400 includes a first rejection mechanism for removing battery cells that do not meet welding standards from the first conveyor line 400.
[0056] Specifically, a quality inspection machine for welding quality inspection is installed on the first conveyor line 400. The quality inspection machine detects the welding position of the battery cells received from the welding turntable 100 on the first conveyor line 400. If a welding quality problem is detected, the battery cell with welding problem is pushed out of the first conveyor line 400 by the first rejection mechanism.
[0057] In the embodiments of this application, such as Figure 4 As shown, the first rejection mechanism includes a rejection cylinder 441 and a receiving tray 442. The rejection cylinder 441 and the receiving tray 442 are located on both sides of the first conveyor line 400. The rejection cylinder 441 pushes the battery cells with welding problems from the first conveyor line 400 to the receiving tray 442 for storage.
[0058] like Figure 4 As shown, the first conveyor line 400 includes a first inspection mechanism for Hi-POT testing of battery cells. The first inspection mechanism is located downstream of the first rejection mechanism. The Hi-POT inspection includes an inspection table, a push cylinder 451, an inspection component 452, and a collection tray 453. The push cylinder 451 pushes the battery cells to be inspected on the conveyor line to the inspection table. The inspection component 452 performs Hi-POT testing on the battery cells to be inspected. If the requirements are met, the handling component of the inspection component 452 will put the qualified battery cells back into the first conveyor line 400. If the requirements are not met, the handling component will store the unqualified battery cells in the collection tray.
[0059] In some embodiments, the first conveyor line 400 includes a first feeding module for automatic loading and flipping of battery cells.
[0060] In specific embodiments, such as Figure 5 As shown, the first feeding module includes a transfer mechanism 461, a fourth conveyor line, an assembly mechanism 463, and a placement rack 464. The placement rack 464 is used to place the casing. The transfer mechanism 461 can transport the battery cells from the first conveyor line 400 to the fourth conveyor line, and simultaneously, it can also transport the battery cells from the fourth conveyor line back to the first conveyor line 400. The gripper on the transfer mechanism 461 can rotate to flip the battery cells. The assembly mechanism 463 picks up the casing from the placement rack 464 and assembles it with the battery cells on the fourth conveyor line. The assembled battery cells return to the first conveyor line 400 and are then transported to the welding turntable 100 for welding. A dust removal device 462 is also installed on the fourth conveyor line.
[0061] In some embodiments, such as Figure 6As shown, the welding turntable 100 includes a base 110 and a rotating body 112. The rotating body 112 is rotatably mounted on the base 110. The base 110 is equipped with a drive motor 111 and a transmission structure. The transmission structure can be a gear. The drive motor 111 drives the rotating body 112 to rotate through the gear.
[0062] The welding mechanism 200 is fixedly installed, and several positioning fixtures 300 are fixed on the rotating body 112. The several sets of positioning fixtures 300 are arranged in a circular array with the rotation center of the rotating body 112 as the center. Driven by the rotating body 112, each positioning fixture 300 can move to the welding mechanism 200 so that the welding mechanism 200 can weld the battery cell positioned on the positioning fixture 300.
[0063] To make welding more efficient, welding mechanism 200 can be equipped with multiple welding machines.
[0064] In this embodiment of the application, the number of positioning fixtures 300 is 18. In one group of positioning fixtures 300, one positioning fixture 300 is used for receiving a cell that requires positive current collector welding, one positioning fixture 300 is used for receiving a cell that requires negative current collector welding, one positioning fixture 300 is used for receiving a cell that requires cover plate penetration welding, one positioning fixture 300 is used for receiving a cell that requires pre-spot welding, one positioning fixture 300 is used for receiving a cell that requires full welding, and one positioning fixture 300 is used for receiving a cell that requires positive electrode post welding.
[0065] The positioning fixture 300 includes a platform 304 and a clamping member 324. The clamping member 324 is rotatable. The platform 304 is used to receive the battery cell. The platform 304 is configured to move closer to or further away from the clamping member 324. When the platform 304 receives the battery cell, during the process of rotating the platform 304 to the welding mechanism 200, the platform 304 moves towards the clamping member 324 with the received battery cell. The platform 304 and the clamping member 324 position and fix the battery cell, which facilitates subsequent welding.
[0066] Before welding, the sensing components of the positioning fixture 300 identify the position on the battery cell that needs to be welded. According to different welding requirements, the clamping component 324 drives the battery cell to rotate to adjust the position of the battery cell to be welded, so as to facilitate welding by the welding mechanism 200. The rotation and adjustment process of the battery cell does not affect the positioning fixture 300 following the rotating body 112. It effectively utilizes the welding window period from the time the positioning fixture 300 receives the battery cell to the time it reaches the welding mechanism 200 to identify and adjust the position of the battery cell to be welded.
[0067] Multiple positioning fixtures 300 are assembled together by using a rotating body 112, which optimizes the arrangement of the fixtures and enables the positioning fixtures 300 to move back and forth between the material receiving station, the welding station and the unloading station. This allows for material feeding and welding in mixed-flow mode (different battery cell materials), enabling welding without stopping the machine and improving welding efficiency.
[0068] In some specific embodiments, such as Figures 7 to 9 As shown, the stage 304 is provided with a positioning groove for limiting the battery cell, and the battery cell received from the incoming material station is positioned in the positioning groove.
[0069] Furthermore, the positioning fixture 300 includes a clamping member 314, which is disposed on the platform 304. The clamping member 314 rises or falls with the platform 304 and is used to clamp the battery cell on the platform 304.
[0070] When it is necessary to clamp and position the battery cell, the state of the battery cell is corrected by the clamping member 314, so that the battery cell is finally positioned correctly between the platform 304 and the clamping member 324, and there will be no situation where the battery cell is skewed and the final welding is incorrect.
[0071] In some embodiments, when the battery cell is adjusted by rotating the clamping member 324, the clamping member 314 releases its grip on the battery cell, and the clamping member 324 rotates electrically through friction. In some embodiments, to make the battery cell rotate more smoothly, a rotating plate is provided in the positioning groove, the rotating plate presses against one end of the battery cell, and the clamping member 324 presses against the other end of the battery cell.
[0072] In some specific embodiments, the clamping member 314 includes a parallel cylinder, and the jaws of the parallel cylinder are provided with clamping blocks for clamping the battery cell. A V-shaped groove is provided on the side of the clamping block for clamping the battery cell, and the battery cell is positioned by the V-shaped groove.
[0073] In some embodiments, the clamping assembly includes a drive member 321, which is connected to the clamping member 324 via a transmission structure to enable precise control of the rotation angle of the clamping member 324, thereby ensuring the accuracy of the cell rotation adjustment.
[0074] like Figures 7 to 9 As shown, the positioning fixture 300 includes a mounting base 301, which has an extension arm extending in a horizontal direction. The clamping member 324 has a connecting end, which is rotatably mounted on the extension arm via a bearing so that the clamping member 324 can rotate.
[0075] In some specific embodiments, the transmission structure includes at least one gear, and the outer periphery of the clamping member 324 is provided with a tooth structure 3241 that cooperates with the gear.
[0076] Among them, the driving component 321 is a motor, which can be a servo motor or a stepper motor.
[0077] The transmission structure of this application includes a gear fixed to the output shaft of the motor, and the gear meshes with the tooth structure 3241 of the clamping plate. The motor rotates and drives the gear, which drives the clamping member 324 to rotate through the tooth structure 3241, thereby enabling the adjustment of the battery cell.
[0078] In some other embodiments, multiple gears may be provided.
[0079] The welding turntable 100 also includes an adjustment assembly for adjusting the distance between the stage 304 and the clamping member 324. Specifically, the adjustment assembly is capable of adjusting the distance between the stage 304 and the clamping member 324 as the stage 304 rotates with the rotating body 112.
[0080] In a specific embodiment, the adjustment component includes an annular trigger 113, which is fixedly installed. The platform 304 abuts against the annular trigger 113. During the rotation of the platform 304 following the rotating body 112, the distance between the platform 304 and the clamping member 324 is adjusted by the annular trigger 113.
[0081] Specifically, the annular trigger 113 includes a first guide structure, a second guide structure, and a third guide structure 1131. The vertical distance between the first guide structure and the clamping member 324 is less than the vertical distance between the third guide structure 1131 and the clamping member 324. The ends of the first guide structure and the second guide structure are connected by the third guide structure 1131. The third guide structure 1131 connects one end of the first guide structure to the other end. The vertical distance between the third guide structure 1131 and the clamping member 324 gradually increases. The first guide structure, the second guide structure, or the third guide structure 1131 abuts against the platform 304.
[0082] The vertical distance between the first guide structure and the clamping member 324 is the same at all points, and the vertical distance between the third guide structure 1131 and the clamping member 324 is the same at all points.
[0083] When the stage 304 abuts against the first guide structure and moves from one end of the first guide structure to the other end, the stage 304 and the clamping member 324 together press and limit the state of the battery cell, which facilitates the welding mechanism 200 to perform welding operations.
[0084] When the platform 304 abuts against the third guide structure 1131 and moves from one end of the third guide structure 1131 to the other, the platform 304 carries the battery cell away from the clamping member 324 or the platform 304 carries the battery cell closer to the clamping member 324. When the platform 304 carries the battery cell away from the clamping member 324, the battery cell can be unloaded. Because there is a height difference between the two ends of the third guide structure 1131, the setting of the third guide structure 1131 makes the clamping and limiting of the battery cell a gradual process, which can avoid damage to the surface of the battery cell during the clamping and positioning process.
[0085] When the stage 304 moves from one end of the second guide structure to the other, the stage 304 can perform loading or unloading of battery cells.
[0086] In a top-down view, the projection of the ring structure formed by the first, second, and third guide structures 1131 connected end to end coincides with the rotation path of the platform 304. This ensures that during the movement of the platform 304 following the rotating body 112, one of the three guide structures 1131 abuts against the platform 304. By setting guide structures at different heights, the distance between the platform 304 and the clamping member 324 can be adjusted, making the adjustment more accurate and stable.
[0087] In other embodiments, the adjustment component may also be a cylinder or an electric push rod, which pushes the platform 304 toward or away from the clamping member 324.
[0088] In some specific embodiments, the stage 304 is slidably mounted on the mounting base 301 via a linear guide rail structure 302.
[0089] In some embodiments, the stage 304 is provided with a rotatable roller 311 that abuts against the annular trigger 113.
[0090] Specifically, such as Figure 9 As shown, a docking part 3041 can be provided on the side of the platform 304 away from the clamping member 324. A roller 311 is provided on the docking part 3041. During the process of the platform 304 rotating with the rotating body 112, due to the setting of the roller 311, the rolling friction of the roller 311 can greatly reduce the friction force and reduce the resistance encountered by the rotating body 112 when rotating.
[0091] In some specific embodiments, the sensing component includes a first sensor 3251 and a second sensor 3252, and different sensors are used to sense the welding position at different locations.
