Description

Technical Field

[0001] This application belongs to the field of battery cell packaging technology, and in particular relates to a battery cell testing and packaging production line and method. Background Technology

[0002] In the production process of photovoltaic cells, after completing processes such as main busbar welding, cells are typically stacked in specific quantities to form cell stacks for transport and subsequent packaging. Before packaging and warehousing, multiple processes are required, including quantity counting, inspection for appearance defects (such as missing corners or microcracks), packing into bags, sealing boxes, and affixing labels. Currently, the industry generally uses manual or semi-automatic methods for these operations, which suffers from high labor intensity, low production efficiency, and high labor costs. Furthermore, manual operation can easily lead to damage to cells during handling and arrangement due to friction or collisions. In addition, the accuracy of manual cell counting and appearance inspection is difficult to guarantee, resulting in poor packaging consistency and impacting overall product quality and brand image. Although some automated equipment has been applied to single processes, the connections between different stages are not smooth, making it difficult to form an efficient, coherent, and flexible complete automated production line. Therefore, there is an urgent need to develop an integrated production line that can automate the entire process of cell stacking, from feeding and counting to inspection and final packaging, to resolve the contradiction between efficiency, quality, and cost in existing technologies. Summary of the Invention

[0003] The main purpose of this application is to provide a production line and method for testing and packaging solar cells. By integrating tilting vibration and regularization with multi-directional air blowing separation, flexible posture handling and adjustment, and automatic bagging and folding with internal support and pressure, it solves the technical problems of inaccurate number of cells, easy damage, low process connection efficiency and inconsistent packaging appearance in the automated packaging of solar cells. It realizes efficient, high-quality and flexible automated production of solar cell stacks from material supply to finished product packaging.

[0004] This application achieves the above objectives through the following technical solution: a battery cell testing and packaging production line, comprising a battery cell feeding mechanism, a battery cell counting mechanism, a battery cell testing mechanism, a bagging mechanism, a bag folding mechanism, a box fastening mechanism, and a labeling mechanism arranged sequentially along the X direction; a first conveying mechanism for transporting battery cell stacks from the battery cell feeding mechanism to the battery cell counting mechanism; a second conveying mechanism for transporting battery cell stacks from the battery cell counting mechanism to the battery cell testing mechanism; a third conveying mechanism for transporting battery cell stacks from the battery cell testing mechanism to the bagging mechanism; a packaging box conveying line for transporting packaging boxes along the X direction to the box fastening mechanism; a packaging box feeding unit disposed beside the packaging box conveying line; a packaging bag feeding mechanism for providing packaging bags to the bagging mechanism; and a fourth conveying mechanism for sequentially transporting battery cell packages from the bagging mechanism to the bag folding mechanism, the box fastening mechanism, and the labeling mechanism.

[0005] Another objective of this application is to provide a method for testing and packaging solar cells, based on the aforementioned solar cell testing and packaging production line, comprising the following steps: S1, The cell feeding mechanism supplies cell stacks; S2. The first conveying mechanism picks up a stack of battery cells from the battery cell feeding mechanism and places it into the battery cell counting mechanism. The battery cell counting mechanism then performs a count of the battery cell stack. S3. The second transport mechanism takes the battery cell stack out of the battery cell counting mechanism and transports it to the battery cell inspection mechanism, which then inspects the battery cell stack for defects. S4. The third handling mechanism takes out the battery cell stack from the battery cell testing mechanism and places it on the bagging mechanism; at the same time, the packaging bag feeding mechanism supplies packaging bags and places the packaging bags on the bagging mechanism. The bagging mechanism opens the bag opening and pushes the battery cell stack into the packaging bag to complete the bagging operation. S5. The fourth handling mechanism transports the battery cell stack with the packaging bag to the bag folding mechanism. The bag folding mechanism folds the excess part of the packaging bag neatly in the reverse direction and covers the battery cell stack, completing the bag folding operation. S6. The fourth handling mechanism transports the folded battery cell stack to the box fastening mechanism. At the same time, the packaging box feeding unit supplies packaging boxes and places them on the packaging box conveyor line. The packaging boxes are then transported to the box fastening mechanism, where the box fastening mechanism fastens the packaging boxes onto the battery cell stack to obtain the battery cell package. S7. The fourth transport mechanism transports the battery cell package to the labeling mechanism, and the labeling mechanism affixes a label to a designated surface of the package to complete the labeling operation.

[0006] Compared with the prior art, the beneficial effects of the battery cell testing and packaging production line and method of this application are as follows: 1. Achieved fully automated and efficient packaging and inspection of solar cell stacks: By organically integrating and intelligently connecting processes such as cell feeding, counting, defect detection, bagging, folding, boxing, and labeling, continuous automated production from cell stacks to finished product packaging has been achieved, significantly improving production efficiency and packaging consistency, and reducing labor costs and operational error risks.

[0007] 2. Employing a unique counting and straightening mechanism improves detection accuracy and safety: By using the first driving component to tilt the carrier, the vibrator to shake, and three sets of air blowing components to blow air from three sides, the battery cells are quickly and neatly aligned and appropriately spread out under the action of gravity. Then, the camera is used to count the images. This method ensures efficient alignment while avoiding friction damage between battery cells, significantly improving the accuracy of counting and the safety of the battery cells.

[0008] 3. Optimize spatial layout and posture conversion mechanisms to improve the compactness and flexibility of the production line: By setting the long side of the cell stack in the counting mechanism to be perpendicular to the production line direction (Y direction), and cooperating with the rotary drive design in the first and third conveying mechanisms, the overall length of the equipment is reduced, while the posture of the cell stack is automatically converted between the feeding, counting, inspection, and bagging stations, making the production line layout more compact and adaptable to multi-specification production.

[0009] 4. The ingenious design of the bagging and folding mechanism enhances packaging reliability and completeness: The bagging mechanism is equipped with a bag pressing module and a layered suction structure for the suction nozzle, which effectively prevents the plastic at the bag opening from shifting when the battery cells are pushed in. The bag folding mechanism provides internal support through the pressure plate, the folding module supports the bag opening internally and flips it 180°, and the pressure plate holds and shapes it, achieving neat and stable folding of the excess parts of the packaging bag, ensuring the appearance and integrity of the packaging.

Detailed Implementation

[0011] Example 1: Please refer to Figures 1-20 This embodiment provides a battery cell testing and packaging production line 100, which includes a battery cell feeding mechanism 1, a battery cell counting mechanism 2, a battery cell testing mechanism 3, a bagging mechanism 4, a bag folding mechanism 5, a box fastening mechanism 6, and a labeling mechanism 7 arranged sequentially along the X direction; a first conveying mechanism 8 that transports a battery cell stack 200 from the battery cell feeding mechanism 1 to the battery cell counting mechanism 2; a second conveying mechanism 9 that transports a battery cell stack 200 from the battery cell counting mechanism 2 to the battery cell testing mechanism 3; a third conveying mechanism 10 that transports a battery cell stack 200 from the battery cell testing mechanism 3 to the bagging mechanism 4; a packaging box conveying line 20 that transports packaging boxes 300 along the X direction to the box fastening mechanism 6; a packaging box feeding unit 30 disposed beside the packaging box conveying line 20; a packaging bag feeding mechanism 40 that provides packaging bags to the bagging mechanism 4; and a fourth conveying mechanism 50 that transports battery cell packages sequentially from the bagging mechanism 4 to the bag folding mechanism 5, the box fastening mechanism 6, and the labeling mechanism 7.

[0012] The first conveying mechanism 8 picks up a stack of battery cells 200 from the battery cell feeding mechanism 1 and places it into the battery cell counting mechanism 2 to complete the counting of the battery cell stack 200. Then, the second conveying mechanism 9 removes the battery cell stack 200 from the battery cell counting mechanism 2 and transports it to the battery cell testing mechanism 3, which checks whether the battery cell stack 200 has missing corners or is broken. Then, the third conveying mechanism 10 removes the battery cell stack 200 from the battery cell testing mechanism 3 and places it into the bagging mechanism 4. At the same time, the packaging bag feeding mechanism 40 supplies packaging bags to the bagging mechanism 4, which opens the bag opening and pushes the battery cell stack 200 into the packaging bag to complete the bagging operation. Then, the fourth conveying mechanism 9... Mechanism 50 transports the battery cell stack 200, which is packaged in a bag, to the bag folding mechanism 5. The bag folding mechanism 5 folds the opening of the bag neatly in the reverse direction and covers the battery cell stack 200, completing the bag folding operation. Then, the fourth transport mechanism 50 transports the bagged battery cell stack 200 to the box fastening mechanism 6. At the same time, the packaging box feeding unit 30 outputs the packaging box 300 to the packaging box conveyor line 20. The packaging box conveyor line 20 transports the packaging box 300 to the box fastening mechanism 6. The box fastening mechanism 6 fastens the packaging box 300 onto the battery cell stack 200, obtaining the battery cell package. The fourth transport mechanism 50 transports the battery cell package to the labeling mechanism 7. The labeling mechanism 7 affixes a label to a designated surface of the packaging box 300, completing the labeling operation.

[0013] The cell feeding mechanism 1 can be implemented using a conventional feeding conveyor line in conjunction with a lifting mechanism. Under normal circumstances, the cell stack 200 is placed in a material box, and the full material box can be transported to the bottom of the first handling mechanism 8 via the feeding conveyor line. Then, the empty material box is transferred to the return conveyor line for recycling via the lifting mechanism or the flat pushing mechanism.

[0014] The cell counting mechanism 2 includes a bracket 21, a first drive member 22 fixed on the bracket 21, a first support plate 23 driven by the first drive member 22 to rotate around a horizontal axis, a vibrator 24 fixed on the first support plate 23, a second support plate 25 disposed at the vibration end of the vibrator 24, a support seat 26 fixed on the second support plate 25 for supporting the cell stack 200, a first air blowing assembly 27 and a second air blowing assembly 28 fixed on the first support plate 23 and aligned with the two adjacent sides of the cell stack 200 on the support seat 26 for blowing air, a first pressing assembly 29 to prevent the cell stack 200 on the support seat 26 from being shaken and scattered by the vibrator 24 in an inclined state, a third air blowing assembly 210 for blowing air on the other side of the cell stack 200 on the support seat 26 in an inclined state, and a first camera 211 for acquiring side image information of the cell stack 200 on the support seat 26.

[0015] The first driving component 22 drives the first support plate 23 to an inclined state, causing the battery cell stack 200 placed on the support seat 26 to also tilt and lean towards the lowest side of the support seat 26, relying on its own gravity to align itself. The first pressing component 29 extends to restrict the position of the outermost battery cell of the battery cell stack 200, preventing it from falling off the support seat 26. The vibrator 24 drives the battery cell stack 200 on the support seat 26 to shake. At the same time, the first air blowing component 27, the second air blowing component 28, and the third air blowing component 210 blow air onto the three sides of the battery cell stack 200, blowing the battery cells inside the battery cell stack 200 into a dispersed state, so that the surface friction between the battery cells is avoided when the battery cells are aligned in the same direction. During the alignment process, the first camera 211 acquires the side image information of the battery cell stack 200, and uses the battery cell counting software program built into the host computer to complete the detection and counting of the number of battery cells based on the image information.

[0016] A limiting support plate 261 is provided on the side of the support base 26 to provide limiting support for the side of the cell stack 200 when the support base 26 is in an inclined state. The first air blowing assembly 27, the second air blowing assembly 28, and the third air blowing assembly 210 all include a first cylinder 271 and an air knife 272 driven by the first cylinder 271 to move linearly. The limiting support plate 261 is provided corresponding to two adjacent sides of the cell stack 200, and the first air blowing assembly 27 and the second air blowing assembly 28 are provided corresponding to the other two adjacent sides of the cell stack 200. The third air blowing assembly 28 blows air onto one of the bottom sides of the inclined cell stack 200. By blowing air onto three sides of the cell stack 200 simultaneously by three air blowing assemblies, one of which is the bottom side, the efficiency of cell alignment can be greatly improved, and the safety of cell alignment can be greatly improved, reducing the risk of cell damage.

[0017] The first pressing assembly 29 includes a second driving member 291 disposed on the inclined side facing the support seat 26, a third support plate 292 driven by the second driving member 291 to move horizontally, and a limiting roller 293 rotatably disposed on the third support plate 292. The second driving member 291 allows the limiting roller 293 to be driven to adapt to the vibration frequency and amplitude of the vibrator 24 for adaptive cell pressing, resulting in higher safety compared to fixed cell limiting.

[0018] The cell inspection mechanism 3 is mainly used to inspect the four sides and four edges of the cell stack 200 for defects. It includes a support platform 31 and several second cameras 32 arranged around the support platform 31. These second cameras 32 are positioned corresponding to the four sides and four edges of the cell stack 200 on the support platform 31 to meet inspection requirements. In this embodiment, because the long side of the cell is relatively long, and the image acquisition area of ​​a single second camera 32 is limited in order to obtain a high-resolution pixel image, two second cameras 32 are provided corresponding to the long side of the cell stack 200. Each second camera 32 is equipped with a light source 33 to illuminate the cell stack 200 on the second support platform 31.

[0019] In this embodiment, the battery cell stack 200 supplied by the battery cell feeding mechanism 1 has its long side parallel to the X direction. If the battery cell stack 200 is placed in the battery cell counting mechanism 2 with its long side extending along the X direction, the overall area occupied by the battery cell counting mechanism 2 in the X direction will increase. However, the battery cell counting mechanism 2 is the bottleneck process in the entire battery cell inspection and packaging production line. In order to improve the overall cycle time, this embodiment arranges two battery cell counting mechanisms 2 side by side along the X direction. If the space occupied by a single battery cell counting mechanism 2 increases, the overall length of the equipment in the X direction will increase. Therefore, in order to reduce the overall length of the equipment in the X direction, the long side of the support seat 26 in the battery cell counting mechanism 2 is arranged parallel to the Y direction to reduce the space occupied by the battery cell counting mechanism 2 in the X direction, thereby reducing the overall length of the equipment.

[0020] However, since the orientation of the cell stack 200 supplied by the cell feeding mechanism 1 is different from that placed in the cell counting mechanism 2, a corresponding design is needed for the structure of the first transport mechanism 8 to meet the transport requirements of the cell stack 200 between the cell feeding mechanism 1 and the cell counting mechanism 2. Therefore, in this embodiment, the first transport mechanism 8 includes a first XZ drive module 81, a fourth support plate 82 disposed at the movable end of the first XZ drive module 81, a third drive member 83 fixed on the fourth support plate 82, a fifth support plate 84 driven by the third drive member 83 to rotate around the Z-axis, and a first gripper module 85 disposed on the fifth support plate 84. By driving the first gripper module 85 to clamp the cell stack 200 and rotate it around the Z-axis through the third drive member 83, the horizontal angle orientation can be changed, thus meeting the transport requirements of the cell stack 200 between the cell feeding mechanism 1 and the cell counting mechanism 2.

[0021] The first gripper module 85 includes a fourth driving member 851 fixed on the fifth support plate 84 and a pair of clamping plates 852 driven by the fourth driving member 851 to perform opening and clamping actions. A support plate 853 supporting the bottom of the battery cell stack is provided at the bottom of the clamping plates 852. The fourth driving member 851 allows for precise control of the clamping distance between the two clamping plates 852, making it suitable for clamping battery cell stacks of various sizes and specifications, thus improving the equipment's versatility. To ensure the stability of the first gripper module 85 in clamping the battery cell stack, each of the two clamping plates 852 is provided with a second pressing assembly 854 that presses the battery cell stack 200 downwards onto the support plate 853 of the clamping plate 852. The second pressing assembly 854 includes a twenty-eighth cylinder 8541 fixed on the clamping plate 852, a movable plate 8542 driven by the twenty-eighth cylinder 8541 to move up and down, and a first pressing plate 8543 elastically mounted on the movable plate 8542. By setting the first pressing plate 8543 to float elastically up and down, the second pressing component 854 can be effectively prevented from damaging the battery cell stack.

[0022] In this embodiment, to save space, the fourth driving component 851 is fixedly mounted in an inverted position on the lower surface of the fifth support plate 84. The body of the fourth driving component 851 is located between the two clamping plates 852, making full use of the space between the two clamping plates 852 to arrange the fourth driving component 851, thereby effectively reducing the overall height space occupied by the first gripper module 85 and achieving the purpose of saving space. In this embodiment, the rotating end of the fourth driving component 851 is provided with a turntable 855. The two clamping plates 852 are respectively horizontally slidably mounted on the fifth support plate 84 via sliders. The two clamping plates 852 are respectively connected to the two ends of the turntable 855 via two connecting rods 856. By rotating the turntable 855, the connecting rods 856 drive the two clamping plates 852 to move closer or further apart. In other embodiments, a drive gear can be provided at the rotating end of the fourth drive member 851, and a rack can be provided on each of the two clamping plates 852. The rack is meshed with the drive gear, and the rotational motion of the drive gear drives the two clamping plates 852 to move closer or further apart under the meshing transmission of the gear and rack.

[0023] In this embodiment, since the long side of the battery cell stack 200 is parallel to the X direction when it is in the bagging mechanism 4, the horizontal angle of the battery cell stack 200 also needs to be adjusted when it is transferred from the battery cell detection mechanism 3 to the bagging mechanism 4. Therefore, in this embodiment, the structure of the third transport mechanism 10 is the same as that of the first transport mechanism 8. A waste discharge port is provided within the transfer range of the third transport mechanism 10. If the battery cell detection mechanism 3 fails the test, the waste is discharged through the third transport mechanism 10.

[0024] The bagging mechanism 4 includes a packaging bag transfer module 41 and a battery cell stack transfer module 42 arranged opposite each other along the Y direction, a first opening module 43 that opens the bag opening of the packaging bag on the packaging bag transfer module 41, and a bag opening holding module 44 that holds the bag opening open. During operation, the packaging bag transfer module 41 receives the packaging bag and moves it to the bagging position. Simultaneously, the battery cell stack transfer module 42 receives the battery cell stack 200 and moves it to the bagging position. The first opening module 43 opens the bag opening, and then the bag opening holding module 44 extends into the bag opening to hold it open. Finally, the battery cell stack transfer module 42 pushes the battery cell stack 200 into the packaging bag, completing the bagging operation.

[0025] The packaging bag transfer module 41 includes a fifth driving component 411, a first support plate 412 driven by the fifth driving component 411 to move along the Y direction, a pair of first suction nozzles 413 fixed on the first support plate 412 and adsorbing the bottom of the packaging bag near the bag opening, a second cylinder 414 fixed on the lower surface of the first support plate 412, a pair of second suction nozzles 415 driven by the second cylinder 414 to move up and down and adsorbing the bottom of the packaging bag near the bag bottom, and a first limiting baffle 416 fixed on the first support plate 412 and limiting the depth of the battery cell stack 200 entering the packaging bag. The first support plate 412 is provided with a plurality of first suction holes 4121 for adsorbing the packaging bag; the first suction holes 4121 ensure that the packaging bag will not shift or flip over during the process of being moved to the bagging position after being placed on the first support plate 412, laying the foundation for the reliable bagging of the battery cell stack 200. In addition, the first suction nozzle 413 and the second suction nozzle 415, together with the first bag opening module 43, can ensure that the packaging bag is effectively opened, thereby ensuring the reliable placement of the battery cell stack 200.

[0026] Because the bottom side of the packaging bag is only held in place by two first suction nozzles 413 near the bag opening, and the battery cell stack 200 is relatively heavy, when the battery cell stack 200 is pushed past the bag opening, it easily rubs the plastic at the bottom of the bag opening, causing the bottom plastic of the bag opening to detach from the suction nozzles 413 and move towards the bottom of the bag along with the battery cell stack 200, ultimately resulting in the failure of the battery cell stack 200 to be put into the bag. To solve this technical problem, the bagging mechanism 4 in this embodiment also includes a bag pressing module 45, which presses the bottom plastic of the bag opening onto the first support plate 412 after the packaging bag moves to the bagging position and before the battery cell stack is pushed into the packaging bag. The bag pressing module 45 is provided with two sets of hooks 452 rotatably mounted on a support 451 and a third cylinder 453 that drives one end of the hook 452 to rotate so that the other end of the hook 452 presses or releases the bottom plastic of the bag opening on the first support plate 412. In some embodiments, the bag-pressing module 45 can be independently disposed in the space below the first support plate 412, and disposed corresponding to the bag-filling position of the first support plate 412. In other embodiments, the bag-pressing module 45 can also be directly disposed on the first support plate 412, specifically disposed on the lower surface of the first support plate 412.

[0027] After the battery cell stack 200 is placed into the packaging bag, it sits on the first support plate 412. Then, the fourth handling mechanism 50 needs to transfer it from the first support plate 412 to the bag folding mechanism 5. In order to facilitate the fourth handling mechanism 50 to pick up the battery cell stack 200 from the first support plate 412, a first gripper clearance slot 4122 is provided on the first support plate 412 corresponding to the bearing area of ​​the battery cell stack 200. One side of the first gripper clearance slot 4122 is an open structure so that the gripper in the fourth handling mechanism 50 can extend into it.

[0028] The cell stack transfer module 42 includes a sixth driving member 421, a second support plate 422 driven by the sixth driving member 421 to move in the Y direction, a fourth cylinder 423 fixed on the second support plate 422, and a first pusher plate 424 driven by the fourth cylinder 423 to move horizontally to push the cell stack 200 on the second support plate 422 into a packaging bag. The second support plate 422 is provided with a first limiting plate 425 that limits the placement position of the cell stack 200 on one side.

[0029] The first bag opening module 43 includes a fifth cylinder 431 and several third suction nozzles 432 that are moved up and down by the fifth cylinder 431 to adsorb the upper layer of plastic at the opening of the packaging bag and open it upwards.

[0030] The bag opening retaining module 44 is provided with two sets, including a sixth cylinder 441, a sixth support plate 442 driven by the sixth cylinder 441 to move in the Y direction, a seventh cylinder 443 fixed on the sixth support plate 442, and a flaring plate 444 driven by the seventh cylinder 443 to move in the X direction. In the initial state, the flaring plates 444 on the two bag opening retaining modules 44 are close together. Driven by the sixth cylinder 441, they extend into the packaging bag in the Y direction. Then, the seventh cylinder 443 drives the flaring plates 444 to move in the X direction, and the distance between the two flaring plates 444 increases, widening the bag opening in the X direction. Only the opening shape is set and maintained so that the battery cell stack can be pushed in smoothly.

[0031] When the bagging mechanism 4 is working, the first support plate 412 is initially at the bag receiving position, and the bag feeding mechanism 40 places the bag on the first support plate 412; the first suction hole 4121 suctions the bag; the first support plate 412 carries the bag and moves to the bagging position; simultaneously, the second support plate 422 is initially at the battery cell stack receiving position, and the third conveying mechanism 10 conveys the battery cell stack 200 onto the second support plate 422; the second support plate 422 carries the battery cell stack 200 and moves to the bagging position; after the bag and battery cell stack 200 are in place, the third suction nozzle 432 in the first bag opening module 43 descends to suction the upper plastic layer of the bag opening. The first suction nozzle 413 adsorbs the lower layer of plastic at the opening of the packaging bag, and then the third suction nozzle 432 moves upward to open the opening of the packaging bag, thus opening the bag. The flaring plate 444 in the bag opening holding module 44 extends into the opening of the packaging bag, widens the opening of the packaging bag to a set shape and holds it. The hook 452 in the bag pressing module 45 presses down the lower layer of the packaging bag opening. At the same time, the second suction nozzle 415 adsorbs the bottom layer of plastic at the bottom of the packaging bag and pulls it downward to ensure that the packaging bag is in a more open state. The fourth cylinder 423 in the battery cell stack transfer module 42 drives the first pusher plate 424 to push the battery cell stack 200 on the second carrier plate 422 into the packaging bag, thus completing the bagging.

[0032] In order to be suitable for feeding packaging bags of various sizes, the packaging bag feeding mechanism 40 in this embodiment includes at least two feeding bins 401 and a packaging bag loading and handling module 402 that picks up packaging bags from the feeding bins 401 and places them on the first support plate 412.

[0033] The folding bag mechanism 5 includes a third support plate 51 that supports the battery cell stack 200, a cover plate module 52 that presses the upper packaging bag of the battery cell stack 200 downward, a second opening bag module 53 that opens the bag opening of the packaging bag outside the battery cell stack 200, a folding module 54 that supports the bag opening and causes the excess part of the packaging bag to fold over the battery cell stack 200, and a third pressing component 55 that presses down the upper packaging bag body of the battery cell stack 200 when the cover plate module 52 is removed.

[0034] The third support plate 51 is provided with a second limiting plate 511 for limiting one side of the battery cell stack 200 and a second gripper clearance slot 512. The second gripper clearance slot 512 is provided at the support area of ​​the battery cell stack 200.

[0035] The cover module 52 includes an eighth cylinder 521, a seventh support plate 522 driven by the eighth cylinder 521 to move along the Y direction, a ninth cylinder 523 fixed on the seventh support plate 522, and a pressing plate 524 driven by the ninth cylinder 523 to move up and down. The pressing plate 524 is moved along the Y direction by the eighth cylinder 521, moving from its initial position to above the battery cell stack 200 on the third support plate 51; the pressing plate 524 is then pressed down by the ninth cylinder 523, pressing it against the battery cell stack 200. The pressing plate 524 against the battery cell stack 200 provides internal support for the reverse bending of the upper plastic layer of the packaging bag during folding, preventing the upper plastic layer from arching and causing folding failure.

[0036] The second bag-opening module 53 includes a first adsorption module 531 for adsorbing the lower layer of plastic at the bag opening and a second adsorption module 532 for adsorbing the upper layer of plastic at the bag opening. The first adsorption module 531 includes a tenth cylinder 5311 and a bag opening adsorption plate 5312 driven by the tenth cylinder 5311 to move up and down. The bag opening adsorption plate 5312 is provided with a plurality of second adsorption holes 53121. The bag opening adsorption plate 5312 is located on the Y-direction side of the third support plate 51. The second adsorption module 532 includes an eleventh cylinder 5321, an eighth support plate 5322 driven by the eleventh cylinder 5321 to move along the Y-direction, a twelfth cylinder 5323 fixed on the eighth support plate 5322, and a plurality of fourth suction nozzles 5324 driven by the twelfth cylinder 5323 to move up and down. By setting the eleventh cylinder 5321, on the one hand, the fourth suction nozzle 5324 is driven to move to the working position to suck up and open the upper plastic of the packaging bag opening; on the other hand, after the folding module 54 extends into the packaging bag, the fourth suction nozzle 5324 is driven to withdraw, providing space for the folding module 54 to realize the folding action of the packaging bag.

[0037] The folding module 54 includes a seventh drive member 541, a ninth support plate 542 driven by the seventh drive member 541 to move along the Y direction, an eighth drive member 543 fixed on the ninth support plate 542, a tenth support plate 544 driven by the eighth drive member 543 to rotate around the X axis, a thirteenth cylinder 545 fixed on the tenth support plate 544, and a pair of inner support plates 546 at the bag opening driven by the thirteenth cylinder 545 to move closer and further away from each other along the X direction. In the initial state, a pair of inner support plates 546 are horizontal and spaced apart on the outside of the bag opening. When the bag opening is opened, the seventh drive unit 541 drives the pair of inner support plates 546 to extend horizontally into the bag to a set depth (e.g., a part of the inner support plate 546 extends into the bag). Then, the thirteenth cylinder 545 drives the two inner support plates 546 to move away from each other and switch to a larger spacing state, flattening the bag opening along the X direction. Then, the eighth drive unit 543 drives the inner support plates 546 to support the bag opening and rotate it around the X axis. At the same time, the seventh drive unit 541 cooperates to move in the Y direction, folding all the excess parts of the bag that are not wrapped with the battery cell stack 180° above the battery cell stack, completing the bag folding operation.

[0038] The third pressing assembly 55 includes a fourteenth cylinder 551, an eleventh support plate 552 driven by the fourteenth cylinder 551 to move up and down, a fifteenth cylinder 553 fixed on the eleventh support plate 552, a twelfth support plate 554 driven by the fifteenth cylinder 553 to move along the Y direction, and a second pressing plate 555 disposed on the top of the twelfth support plate 554. The second pressing plate 555 is located between the third bearing plate 51 and the second bag opening module 53. The fourteenth cylinder 551 drives the second pressing plate 555 to perform up and down pressing action, and the fifteenth cylinder 553 drives the second pressing plate 555 to move along the Y direction, so that the second pressing plate 555 moves above the battery cell stack 200 for effective pressing. Since the second pressing plate 555 is pressing the packaging bag on one side of the upper surface of the battery cell stack 200, the cover plate 524 is also pressing the upper surface of the battery cell stack 200 through the packaging bag at the same time. Therefore, the cover plate 524 will hinder the second pressing plate 555 from pressing the packaging bag on the battery cell stack 200. In order to solve this technical problem, in this embodiment, multiple second pressing plates 555 are arranged at intervals along the X direction, and the cover plate 524 is provided with a clearance notch 5241 to avoid the second pressing plate 555, so that when the cover plate 524 is pressing the upper surface of the battery cell stack, the second pressing plate 555 can also press the packaging bag on one side of the upper surface of the battery cell stack.

[0039] When the bag folding mechanism 5 is working, the fourth transport mechanism 50 places the battery cell stack 200 on the third support plate 51. The pressure plate 524 in the cover module 52 moves to directly above the battery cell stack 200 and presses down to hold the packaging bag body on the upper surface of the battery cell stack 200. At this time, the bag opening is located between the first adsorption module 531 and the second adsorption module 532. The bag opening adsorption plate 5312 in the first adsorption module 531 adsorbs the lower layer of plastic at the bag opening, and the fourth suction nozzle 5324 in the second adsorption module 532 adsorbs the upper layer of plastic at the bag opening, thus opening the bag opening. Then, the inner support plate 546 in the folding module 54 extends into the packaging bag to support the bag opening, and then the bag opening is folded. Fold all the excess portion of the packaging bag that is not covering the battery cell stack above the pressure plate 524; the inner support plate 546 of the bag opening is removed from the packaging bag, and the excess portion of the packaging bag falls onto the pressure plate 524 in a roughly flat state; at this time, the packaging bag partially covers the pressure plate 524 in a C-shape. If the pressure plate 524 is directly pulled out, the upper plastic layer of the packaging bag will move along with the pressure plate 524, resulting in failure of folding. Therefore, the second pressure plate 555 in the third pressure assembly 55 presses down on the bent area of ​​the packaging bag and holds it on the battery cell stack 200; then the pressure plate 524 is pulled out from the C-shaped covering structure of the packaging bag, so that the upper plastic layer of the packaging bag will not be carried away, and the packaging bag will remain in the folded state; the folding is completed.

[0040] The packaging box feeding unit 30 includes a packaging box feeding device 301 and a fifth conveying mechanism 302 that picks up packaging boxes 300 from the packaging box feeding device 301 and places them onto the packaging box conveyor line 20.

[0046] When the box-locking mechanism 6 is working, the fourth conveying mechanism 50 transports the cell stack 200 onto the fourth support plate 61, and the first alignment module 62 aligns the two sides of the cell stack 200. At the same time, the packaging box 300 is conveyed to the end via the packaging box conveyor line 20. The pushing component 632 pushes the packaging box 300 onto the lifting component 631, the second alignment module 6314 corrects the position of the two sides of the packaging box 300, and the lifting component 631 lifts the packaging box 300 to a set height. The packaging box adsorption component 644 in the box-locking module 64 picks up the packaging box 300 from the lifting component 631 and moves it above the fourth support plate 61, and then locks it onto the cell stack 200, completing the box-locking operation.

[0048] The labeling mechanism 7 includes a sixth carrier plate 71 that carries the battery cell package, a label supply module 72 located on one side of the sixth carrier plate 71, a labeling module 73 that takes out the label from the label supply module 72 and affixes it to the package box 300, and a sixth transport mechanism 74 that takes out the battery cell package from the sixth carrier plate 71 and moves it to the labeling position of the labeling module 73.

The first conveying mechanism 8 picks up the battery cell stack 200 from the battery cell feeding mechanism 1 and places it into the battery cell counting mechanism 2.

S7. The fourth transport mechanism 50 transports the battery cell package to the labeling mechanism 7, and the labeling mechanism 7 affixes a label to a designated surface of the packaging box 300 to complete the labeling operation.

18. A method for testing, packaging, and manufacturing battery cells, characterized in that, Based on the battery cell testing and packaging production line as described in any one of claims 1 to 17, the process includes the following steps: S1, The cell feeding mechanism supplies cell stacks; S2. The first conveying mechanism picks up a stack of battery cells from the battery cell feeding mechanism and places it into the battery cell counting mechanism. The battery cell counting mechanism then performs a count of the battery cell stack. S3. The second transport mechanism takes the battery cell stack out of the battery cell counting mechanism and transports it to the battery cell inspection mechanism, which then inspects the battery cell stack for defects. S4. The third handling mechanism takes out the battery cell stack from the battery cell testing mechanism and places it on the bagging mechanism; at the same time, the packaging bag feeding mechanism supplies packaging bags and places the packaging bags on the bagging mechanism. The bagging mechanism opens the bag opening and pushes the battery cell stack into the packaging bag to complete the bagging operation. S5. The fourth handling mechanism transports the battery cell stack with the packaging bag to the bag folding mechanism. The bag folding mechanism folds the excess part of the packaging bag neatly in the reverse direction and covers the battery cell stack, completing the bag folding operation. S6. The fourth handling mechanism transports the folded battery cell stack to the box fastening mechanism. At the same time, the packaging box feeding unit supplies packaging boxes and places them on the packaging box conveyor line. The packaging boxes are then transported to the box fastening mechanism, where the box fastening mechanism fastens the packaging boxes onto the battery cell stack to obtain the battery cell package. S7. The fourth transport mechanism transports the battery cell package to the labeling mechanism, and the labeling mechanism affixes a label to a designated surface of the package to complete the labeling operation.
