Description

Technical Field

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

[0002] As the core component of solar cells, photovoltaic cells require post-production inspection for appearance defects and quantity counting, followed by packaging in specialized boxes for product protection and ease of transport. Traditional manual or semi-automatic operation methods are inefficient, labor-intensive, and prone to causing microcracks or contamination in the cells, making them unsuitable for large-scale mass production.

[0003] Currently, there is a type of battery cell packaging structure that directly loads multiple stacks of battery cells into a packaging box. The battery cells in the stack are small pieces, such as two-piece, three-piece, or four-piece pieces. Some automated testing and packaging equipment has also emerged in the industry. For example, patent CN118083289B discloses an automatic battery cell packaging machine. However, this packaging machine can only package whole stacks of battery cells into boxes. Furthermore, this mechanism requires first placing the battery cell stack into a packaging bag and then placing it into a packaging box. The packaging box structure of this machine differs from the packaging box structure in the aforementioned battery cell packaging structure. Therefore, this packaging machine cannot be directly applied to the automated packaging of the aforementioned battery cell packaging structure.

[0004] Therefore, it is necessary to develop a new production line and method for testing, packaging, and boxing battery cells to solve the above-mentioned technical problems. Summary of the Invention

[0005] The main purpose of this application is to provide a production line and method for testing, boxing and packaging of battery cells, which can realize the automatic testing and boxing of multiple small battery cell stacks, greatly improving production efficiency.

[0006] This application achieves the above objectives through the following technical solution: a battery cell testing, boxing, and packaging production line, comprising: The cell stack feeding conveyor line transports the cell boxes loaded with cell stacks in the reverse direction along X. The packaging box feeding conveyor is arranged parallel to the battery cell stack feeding conveyor and conveys the packaging boxes in the reverse direction along the X direction. The first production unit and the second production unit are located on both sides of the cell stack feeding conveyor line in the Y direction, and each includes a cell counting mechanism, a cell testing mechanism, a cell boxing and closing device, a labeling mechanism and a unloading device arranged sequentially in the X direction, a first conveying mechanism for transporting the cell stack from the cell counting mechanism to the cell testing mechanism, a second conveying mechanism for transporting the cell stack from the cell testing mechanism to the cell boxing and closing device, and a third conveying mechanism for transporting the packaging box containing the cell stack from the cell boxing and closing device, labeling it through the labeling mechanism, and then placing it into the unloading device. The battery cell loading and handling mechanism takes out the battery cell stack from the battery cell box on the battery cell stack feeding conveyor line and places it on the battery cell counting mechanism. The packaging box feeding and conveying mechanism transports the packaging boxes from the packaging box feeding conveyor line to the battery cell boxing and closing device.

[0007] Another objective of this application is to provide a method for the production of battery cell testing, boxing, and packaging, based on the aforementioned battery cell testing, boxing, and packaging production line, comprising: S1, The cell stack feeding conveyor line transports the cell material box containing multiple cell stacks in the reverse direction along X to the end; S2. The cell loading and handling mechanism removes all the cell stacks from the cell material box on the cell stack feeding conveyor line and places them on the cell counting mechanism in the first or second production unit. S3. The cell counting mechanism simultaneously detects the number of cells in multiple cell stacks. S4. The first conveying mechanism moves multiple stacks of solar cells from the solar cell counting mechanism to the solar cell testing mechanism; S5. The battery cell testing organization simultaneously performs defect testing on multiple battery cell stacks. S6. During the execution of S1~S5, the packaging box feeding conveyor line transports the closed packaging box in the reverse direction along X to the end, and uses the box opening and transfer mechanism to operate the packaging box to the open state; the packaging box loading and handling mechanism transports the open packaging box to the battery cell boxing and closing device. S7. The second conveying mechanism moves multiple battery cell stacks from the battery cell detection mechanism to the battery cell boxing and closing device, and with the assistance of visual positioning, puts the multiple battery cell stacks into the packaging box, and operates the packaging box containing the multiple battery cell stacks to the closed state through the battery cell boxing and closing device to obtain the package. S8. The third handling mechanism moves the package from the battery cell boxing and closing device through the labeling mechanism, outputs the label through the labeling mechanism, and affixes the label to the designated position on the package. S9. The third handling mechanism continues to move the packaged parts to the unloading device. If the tests in S3, S5 and S7 are all qualified, the parts are output through the finished product unloading conveyor line; otherwise, the parts are output through the defective product unloading conveyor line.

[0008] Compared with the prior art, the beneficial effects of the battery cell inspection, boxing and packaging production line and method of this application are as follows: it realizes a series of automated operations such as automatic feeding of multiple battery cell stacks, quantity and defect detection, automatic feeding of packaging boxes, boxing of multiple battery cell stacks and labeling, which meets the automatic inspection and packaging process requirements of multi-cell battery stacks and improves production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. The implementation methods of this application will now be described based on its overall structure.

[0012] Please refer to Figures 1-26This embodiment provides a battery cell testing, packaging, and assembly line 100, which includes a battery cell stack feeding conveyor 1 that conveys battery cell stacks 400 in the reverse X direction, a packaging box feeding conveyor 2 that is parallel to the battery cell stack feeding conveyor 1 and conveys packaging boxes 500 in the reverse X direction, a first production unit 200 and a second production unit 300 located on both sides of the battery cell stack feeding conveyor 1 in the Y direction, a battery cell loading and transporting mechanism 3 located at the end of the battery cell stack feeding conveyor 1 and transporting the battery cell stacks 400 on the battery cell stack feeding conveyor 1 to the first production unit 200 and the second production unit 300 respectively, and a packaging box loading and transporting mechanism located at the end of the packaging box feeding conveyor 2 and transporting the packaging boxes 500 on the packaging box feeding conveyor 2 to the first production unit 200 and the second production unit 300 respectively. 4; The first production unit 200 and the second production unit 300 have the same structure and both include a cell counting mechanism 5, a cell inspection mechanism 6, a cell boxing and closing device 7, a labeling mechanism 8, and a feeding device 9 arranged sequentially along the X direction; a first conveying mechanism 10 that transports the cell stack 400 from the cell counting mechanism 5 to the cell inspection mechanism 6; a second conveying mechanism 20 that transports the cell stack 400 from the cell inspection mechanism 6 to the cell boxing and closing device 7; and a third conveying mechanism 30 that transports the packaging box 500 (hereinafter referred to as "packaging 600") containing the cell stack 400 from the cell boxing and closing device 7 to the labeling mechanism 8 for labeling and then placing it in the feeding device 9; the packaging box feeding and conveying mechanism 4 transports the packaging box 500 on the packaging box feeding conveyor line 2 to the cell boxing and closing device 7.

[0013] In this embodiment, the first transport mechanism 10, the second transport mechanism 20, and the third transport mechanism 30 are all mounted on linear modules. The cell loading and transport mechanism 3 is a multi-axis robot positioned above the cell stack feeding and conveying line 1. The first transport mechanism 10, the second transport mechanism 20, and the third transport mechanism 30 in the first production unit 200 and the second production unit 300 are all located on the outermost sides in the Y direction, and an installation space is formed between the transport mechanisms on the outermost sides in the Y direction. The cell counting mechanism 5, the cell detection mechanism 6, and the cell boxing and capping device 7 in the two production units are all located within the installation space. Through the above layout, on the one hand, the transport mechanisms on the outermost sides in the Y direction will not interfere with the activity space of the cell loading and transport mechanism 3, so that the cell loading and transport mechanism 3 has enough space to realize the loading and transport of the cell stack 400 in the first production unit 200 and the second production unit 300. On the other hand, the overall length of the entire production line in the Y direction can be greatly reduced, and the area occupied by the production line can be reduced. Furthermore, if the cell loading and handling mechanism 3 is not a multi-axis robot but a linear module, it can only be positioned on the opposite side of the X-axis at the end of the cell stack feeding conveyor line 1, and its range of motion covers the first production unit 200 and the second production unit 300 in the Y-axis, thus increasing the overall length of the entire production line in the X-axis direction. In this embodiment, the cell loading and handling mechanism 3 is positioned above the cell stack feeding conveyor line 1 using a multi-axis robot, making full use of the height space of the factory and reducing the overall length of the entire production line in the X-axis direction.

[0014] In addition, since the cell counting mechanism 5 is a bottleneck process, in order to ensure the overall cycle time, in this embodiment, two cell counting mechanisms 5 are arranged side by side along the X direction. Compared with the linear module loading system, the cell loading and handling mechanism 3 uses a multi-axis robot, which has a faster loading speed and can better meet the cell stack 400 loading cycle time requirements of the four cell counting mechanisms 5.

[0015] The cell stack 400 is placed in the cell cassette 700 and transported to the cell stack feeding position via the cell stack feeding conveyor line 1. After the cell loading and handling mechanism 3 removes the cell stack 400 from the cell cassette 700, the empty cell cassette 700 needs to be recycled. Therefore, in this embodiment, a cassette return conveyor line 11 is provided below the cell stack feeding conveyor line 1, and a first lifting module 12 is provided at the end of the cell stack feeding conveyor line 1. The cell cassette 700 is transferred from the cell stack feeding conveyor line 1 to the cassette return conveyor line 11 via the first lifting module 12.

[0016] The packaging box 500, in a closed state, is conveyed to the packaging box feeding position via the packaging box feeding conveyor line 2. Since the packaging box 500 needs to be open when loading the battery cell stack 400, this embodiment includes an opening and transfer mechanism 40 at the end of the packaging box feeding conveyor line 2. Furthermore, because the packaging box 500 may be placed on the packaging box feeding conveyor line 2 in the wrong direction, preventing the opening and transfer mechanism 40 from effectively opening the box, this embodiment also includes a first camera (not shown in the figure) on the packaging box feeding conveyor line 2 upstream of the opening and transfer mechanism 40 to detect whether the packaging box 500 is placed in the correct orientation, and a direction adjustment mechanism 21 to adjust the packaging box 500 to the correct orientation when it is placed in the wrong direction.

[0017] The orientation adjustment mechanism 21 includes a first cylinder 211, a second cylinder 212 driven by the first cylinder 211 to move up and down, a rotating disk 213 driven by the second cylinder 212 to rotate around the Z-axis, and a plurality of first suction nozzles 214 disposed on the rotating disk 213. When the first camera detects a packaging box with reverse orientation, the first cylinder 211 drives the rotating disk 213 to rise and lift the packaging box upward, while simultaneously adsorbing and fixing the packaging box through the first suction nozzles 214. Then, the second cylinder 212 drives the rotating disk 213 to rotate 170°, reversing the front and back orientations of the packaging box, thereby achieving orientation adjustment of the packaging box.

[0018] The packaging box 500 in this embodiment has a unique structure, comprising a base plate A, a surrounding section B, and a top cover C. The surrounding section B is formed by surrounding plates B1, B2, B3, and B4, which are connected to the four edges of the base plate A. One edge of the top cover C is connected to the top edge of the surrounding plate B1. There is no connecting structure between the surrounding plates B1, B2, B3, and B4. Each of the three edges of the top cover C has a edging. The surrounding section B is maintained in its enclosed state solely by the closing constraint of the top cover C. Specifically, when the top cover C is closed, the tops of three of the surrounding plates B2-B4 are restrained within the edging of the top cover C, thus maintaining the enclosed state. Therefore, when the top cover C is opened, the surrounding section B loses its closing constraint and opens up. In this embodiment, the packaging box formed into a cube shape is referred to as a formed packaging box, and the packaging box in its unfolded state is referred to as an unfolded packaging box.

[0019] Regarding the opening operation of the aforementioned packaging box 500, this embodiment optimizes the opening method of the packaging box. Specifically, it includes the following steps: (1) First, open an opening between the top cover C of the packaging box and the enclosure B. At this time, the top cover C is completely separated from the top of the enclosure B3. Therefore, while the enclosure B3 loses the enclosure constraint of the top cover C, the top cover C also loses the pulling constraint of the enclosure B3. As a result, the enclosure B1 loses the enclosure constraint and will tilt in the X direction. Therefore, the flipping axis of the top cover C will move and its position will be uncertain. Therefore, the top cover C cannot be opened by the conventional flipping method. (2) Then a stop bar is used to block the opening; the height of the stop bar is slightly higher than the height of the enclosure part B in the closed state, so that the enclosure part B of the packaging box can pass through the stop bar smoothly, while the top cover C of the packaging box will be blocked by the stop bar. (3) Hold the packaging box and move it horizontally in the opposite direction of X, so that the entire packaging box passes through the stop bar. Use the stop bar to block the top cover C to open the top cover C automatically. After opening, the top cover C will tilt in the opposite direction of X, and then pass through the stop bar to open the box.

[0020] To achieve the aforementioned automatic box opening method, this embodiment correspondingly designs the structure of the box opening and transfer mechanism 40. Specifically, the box opening and transfer mechanism 40 includes a blocking module 401 that blocks the packaging box 500 on the packaging box feeding conveyor line 2 at the first packaging box feeding position; a first X-axis transfer module 402 located below the packaging box feeding conveyor line 2 and transferring the packaging box 500 from the first packaging box feeding position to the second packaging box feeding position; a first support plate 403 located at the movable end of the first X-axis transfer module 402; a lifting module 404 fixed on the first support plate 403 and adsorbing and lifting the packaging box 500; and a box opening module 405 fixed on the first support plate 403 and opening an opening between the top cover of the packaging box 500 and the packaging box body.

[0021] The first support plate 403 is driven by the first X-axis transfer module 402 to reciprocate between the first packaging box feeding position and the second packaging box feeding position in the X direction.

[0022] The blocking module 401 includes a third cylinder 4011 and a stop bar 4012 that is driven by the third cylinder 4011 to move up and down and spans above the packaging box feeding conveyor line 2. The stop bar 4012 is driven by the third cylinder 4011 to reciprocate between a first height position and a second height position. At the first height position, the stop bar 4012 blocks the packaging box 500 from moving forward, thereby blocking the packaging box at the first packaging box feeding position. At the second height position, the stop bar 4012 is within the opening height range, allowing the packaging box's enclosure part B to pass through on one hand, and blocking the packaging box's top cover C to a fully open state on the other hand. Finally, the fully opened top cover C passes under the stop bar 4012, and the packaging box 500 moves to the second packaging box feeding position.

[0023] The lifting module 404 includes a fourth cylinder 4041 fixed on a first support plate 403 and an adsorption plate 4042 driven by the fourth cylinder 4041 to move up and down. The adsorption plate 4042 holds the bottom plate A of the packaging box by vacuum adsorption.

[0024] The box-opening module 405 includes a first driving member 4051 fixed to a first support plate 403, a second support plate 4052 driven by the first driving member 4051 to rotate around the Y-axis, and a second suction nozzle 4053 fixed to the second support plate 4052 for adsorbing the top cover C of the packaging box. The first driving member 4051 drives the second suction nozzle 4053 to adsorb the top cover C and rotate it around the Y-axis, thereby opening the top cover C from the barrier portion B to form the opening. Simultaneously, after adsorbing the top cover C and opening an opening, the second suction nozzle 4053 can also rotate to the rear and lower side of the top cover C, which on the one hand does not hinder the subsequent opening of the top cover C, and on the other hand allows it to pass smoothly under the stop bar 4012 at the second height position.

[0025] The battery cell loading and handling mechanism 3 includes a multi-axis robot 31, a third support plate 32 disposed at the moving end of the multi-axis robot 31, and a plurality of first gripper modules 33 disposed on the third support plate 32. This embodiment illustrates a battery cell inspection, boxing, and packaging production line applied to the inspection, boxing, and packaging of multi-cell (e.g., three-cell or four-cell) products. Therefore, multiple battery cell stacks 400 are placed side by side in the battery cell box 700. Consequently, multiple sets of first gripper modules 33 are correspondingly provided to enable the removal of all battery cell stacks 400 from the battery cell box 700 at once. In this embodiment, three first gripper modules 33 are provided, corresponding to the three battery cell stacks in the battery cell box. Simultaneously, a packaging box 500 also accommodates three battery cell stacks at the same time.

[0026] Furthermore, the spacing between the multiple cell stacks 400 within the cell cassette 700 is relatively small, while the spacing between the multiple cell stacks 400 within the cell counting mechanism 5 is slightly larger. Therefore, to adjust the spacing between the cell stacks within the cell cassette 700 and the cell counting mechanism 5, a spacing adjustment cylinder 34 is also provided on the third support plate 32 to adjust the spacing between two adjacent first gripper modules 33. In this embodiment, two spacing adjustment cylinders 34 are provided. The first gripper module 33 located in the middle is fixedly mounted on the third support plate 32, and the two first gripper modules 33 on either side of the first gripper module 33 are each driven by a spacing adjustment cylinder 34 to adjust the spacing between themselves and the middle first gripper module 33.

[0027] In other embodiments, if the spacing between the multiple cell stacks 400 in the cell cassette 700 is equal to the spacing within the cell counting mechanism 5, then the cell loading and handling mechanism 3 does not need to be equipped with a spacing adjustment cylinder 34.

[0028] The packaging box loading and conveying mechanism 4 includes a first conveying module 41 and a second conveying module 42. The first conveying module 41 is used to load packaging boxes into the first production unit 200, and the second conveying module 42 is used to load packaging boxes into the second production unit 300, thereby improving the loading efficiency of packaging boxes. Both the first conveying module 41 and the second conveying module 42 include a YZ transfer module 411, a fourth support plate 412 disposed at the movable end of the YZ transfer module 411, and a plurality of suction rods 413 fixed on the fourth support plate 412 for adsorbing the bottom plate A of the packaging box.

[0029] After the top cover C of the packaging box 500 is opened by the box opening and transfer mechanism 40, the surrounding baffles will tilt outwards. However, there may be cases where the tilting is not obvious, which can easily affect the picking up of the packaging box 500. To solve this technical problem, the first handling module 41 and the second handling module 42 also include a side push module 414 disposed on the fourth support plate 412 for pushing the surrounding baffles of the packaging box outwards. The side push module 414 includes a fifth cylinder 4141 fixed on the fourth support plate 412, a fifth support plate 4142 driven by the fifth cylinder 4141 to move up and down, several sixth cylinders 4143 fixed on the fifth support plate 4142, and a side push plate 4144 driven by the sixth cylinders 4143 to move horizontally. The side push plate 4144 is provided with multiple baffles for the packaging box, and the side push plates 4144 acting on the same baffle share the same sixth cylinder 4143 to provide driving thrust.

[0030] When the first transport module 41 and the second transport module 42 are in operation, the YZ transfer module 411 drives the fourth support plate 412 to move to a set height, and then the fifth cylinder 4141 drives the fifth support plate 4142 to descend. At this time, the side push plate 4144 is within the height range of the enclosure section B and above the bottom plate A. The sixth cylinder 4143 drives the side push plate 4144 to push out horizontally, pushing the surrounding enclosure plates outward. During this action, the side push plate 4144 may push the enclosure plate or it may not push the enclosure plate. For example, if the enclosure plate tilts too much and exceeds the range of action of the side push plate 4144, the side push plate 4144 will not push the enclosure plate; if the enclosure plate tilts too little and is within the range of action of the side push plate 4144, the side push plate 4144 will push the enclosure plate.

[0031] The cell counting mechanism 5 is mainly used to neatly arrange the cell stack 400 and perform cell counting detection. It includes a vibrator 51, a bracket 52 set at the vibrating end of the vibrator 51, a second drive member 53 fixed on the bracket 52, a sixth support plate 54 driven by the second drive member 53 to rotate around a horizontal axis, several first support seats 55 set on the sixth support plate 54 for supporting the cell stack 400, a first air blowing assembly 56 blowing air on one short side of the cell stack 400, a second air blowing assembly 57 blowing air on the other short side of the cell stack 400, a third air blowing assembly 58 blowing air on one long side of the cell stack 400, a pressing assembly 59 preventing the cell stack inside the first support seat 54 from falling when the first support seat 54 is flipped and tilted, and several second cameras (not shown in the figure) for acquiring image information of the cell stack 400 on the first support seat 55 for cell counting.

[0032] In this embodiment, by setting up the vibrator 51, and cooperating with the second driving member 53 to drive the battery cell stack 400 to an inclined state, coupled with the synergistic effect of multiple air blowing components, the efficiency of the battery cell stack to be neat and orderly can be greatly improved, and the risk of friction damage to the surface of the battery cells can be greatly reduced during the process of the battery cells being smoothly smoothed to an orderly state.

[0033] In this embodiment, the entire device is mounted on the vibrator 51. The vibrator 51, in conjunction with the second driving component 53, drives the battery cell stack 400 to an inclined state, thereby quickly and neatly aligning the battery cell stack 400.

[0034] In other embodiments, the vibrator 51 may be mounted on the sixth support plate 54, and the first bearing seat 55 may be mounted on the vibrating end of the vibrator 51, so that the vibrator 51 can directly act on the first bearing seat 55 to provide vibration capability. The cell counting mechanism 5 includes a bracket 52, a second drive member 53 fixed on the bracket 52, a sixth support plate 54 driven by the second drive member 53 to rotate around a horizontal axis, a vibrator 51 fixed on the sixth support plate 54, a vibrating base plate disposed at the vibrating end of the vibrator 51, a plurality of first support seats 55 disposed on the vibrating base plate and used to support the cell stack 400, a first air blowing assembly 56 blowing air on one short side of the cell stack 400, a second air blowing assembly 57 blowing air on the other short side of the cell stack 400, a third air blowing assembly 58 blowing air on one long side of the cell stack 400, a pressing assembly 59 preventing the cell stack inside the first support seat 54 from falling when the first support seat 54 is flipped and tilted, and a plurality of second cameras (not shown in the figure) for acquiring image information of the cell stack 400 on the first support seat 55 for quantity detection.

[0035] The first support seat 55 is provided with a first limiting baffle 551 that supports the short side of the battery cell stack near the bottom when the battery cell stack is flipped to an inclined state, and a second limiting baffle 552 that supports the long side of the battery cell stack near the bottom.

[0036] The first air blowing assembly 56, the second air blowing assembly 57, and the third air blowing assembly 58 have the same structure and each includes a seventh cylinder 561 and an air blowing block 562 driven by the seventh cylinder 561 to move linearly.

[0037] The pressing assembly 59 includes a third driving member 591, a seventh support plate 592 driven by the third driving member 591 to move closer to or away from the first support seat 55, and a plurality of first rolling rollers 593 disposed on the seventh support plate 592.

[0038] In this embodiment, three first support seats 55 are arranged side by side to simultaneously complete the arrangement and counting of three battery cell stacks. Three first air blowing components 56, three second air blowing components 57, three third air blowing components 58, and three first rolling rollers 593 are each provided, corresponding to the three first support seats 55. In other embodiments, one, two, or four first support seats 55 may be provided, and the number of first air blowing components 56, 57, 58, and 593 corresponds to the number of first support seats 55.

[0039] The first air-blowing assembly 56 is fixedly mounted on the sixth support plate 54 and rotates together with the sixth support plate 54 and the first carrier 55. The second air-blowing assembly 57 is independently mounted on the side of the sixth support plate 54 and blows air onto the short side of the battery cell stack 400 when the first carrier 55 is rotated to an inclined state.

[0040] When three cell stacks 400 are placed in three side-by-side first support seats 55, if air needs to be blown along one long side of a cell stack 400, the air blowing block 562 in the air blowing assembly needs to extend between two adjacent first support seats 55. However, the side of the first support seat 55 that is flipped over also needs to accommodate the pressing assembly 59. Therefore, it is not convenient to lay out the third air blowing assembly 58. To solve this problem, in this embodiment, the third air blowing assembly 58 is set on the pressing assembly 59. Specifically, the third air blowing assembly 58 is set on the seventh support plate 592 of the pressing assembly 59. As the seventh support plate 592 approaches the top surface of the cell stack, the seventh cylinder 561 in the third air blowing assembly 58 drives the air blowing block 562 to extend between two cell stacks and blow air along the long side of the cell stack.

[0041] The cell inspection mechanism 6 is mainly used to inspect the neat and orderly cell stack 400 for defects such as fragments and missing corners, and includes a second support 61 that supports the cell stack 400 and several visual inspection modules 62 arranged around the second support 61.

[0042] According to the process requirements, defect detection of the solar cells requires inspection of the four sides and four lateral edges of the solar cell stack 400. Therefore, at least six sets of vision inspection modules 62 are needed to meet the above process requirements. However, in this embodiment, three solar cell stacks 400 constitute one packaging unit. To improve packaging efficiency, both the solar cell counting mechanism 5 and the solar cell inspection mechanism 6 are designed to operate on all three solar cell stacks 400 simultaneously. Therefore, in this embodiment, three second support seats 61 are provided to support all three solar cell stacks 400 simultaneously, and the vision inspection modules 62 are located on the overall periphery of the three second support seats 61.

[0043] To meet the defect detection requirements of three cell stacks 400, and in order to minimize the number of vision inspection modules 62, thereby reducing setup costs and allowing for a sufficient number of modules to be deployed within a limited area, this embodiment uses a single vision inspection module 62 to inspect the same object (e.g., a side surface or edge in the same orientation) across the three cell stacks 400. However, since the three cell stacks 400 are located in different positions, and the focal length of the vision inspection module 62 is fixed, when the same vision inspection module 62 takes pictures of the side surface or edge of the same orientation of cell stacks 400 at different locations, the images of one or two cell stacks 400 may become blurry due to the varying distances between the lens and the stacks, leading to inaccurate defect detection. Therefore, to solve this technical problem, this embodiment optimizes the structure of the cell inspection mechanism 6. Specifically, the cell inspection mechanism 6 also includes a position adjustment module 63 for adjusting the position of the vision inspection modules 62. The position adjustment module 63 includes a fourth driving member 631 and an eighth support plate 632 driven by the fourth driving member 631 to move along the arrangement direction of the second support seat 61. All the vision inspection modules 62 are mounted on the eighth support plate 632. By driving the vision inspection modules 62 along the arrangement direction of the second support seat 61 with the fourth driving member 631, the positions of those vision inspection modules 62 that need to be adjusted can be adjusted to obtain clear images of corresponding parts of each cell stack 400. The vision inspection module 62 includes a third camera 621 and a light source 622.

[0044] Furthermore, when the three battery cell stacks 400 are arranged in a row, there is a problem of adjacent battery cell stacks occluding each other, causing the occluded side to be unable to obtain a valid image. To solve this technical problem, the battery cell detection mechanism 6 in this embodiment also includes several fifth driving members 64 that drive each second support 61 to move independently up and down. By driving the second support 61 to move up and down through the fifth driving members 64, the battery cell stacks 400 are misaligned in the height direction. When a battery cell stack is being detected, the corresponding fifth driving member 64 drives the second support 61 carrying that battery cell stack 400 to rise to the detection height, while the other battery cell stacks 400 remain at a low position, thus avoiding occlusion interference with the battery cell stacks 400 being detected.

[0045] The first handling mechanism 10 includes a first XZ transfer module 101, a ninth support plate 102 driven by the first XZ transfer module 101, and a plurality of second gripper modules 103 fixed on the ninth support plate 102. Multiple second gripper modules 103 simultaneously clamp and transport multiple battery cell stacks 400, meeting the handling requirements of multiple battery cell stacks 400.

[0046] However, considering that the lengths of solar cells of different sizes will vary, and that stacks of solar cells 400 of different lengths are placed on the first support seat 55 in the solar cell counting mechanism 5, after being tilted and aligned, they will abut against the same reference position. This results in different center positions for the stacks of solar cells 400 of different lengths after alignment. To ensure that the first transport mechanism 10 can always grasp the center position of the stacks of solar cells 400 of different lengths when gripping them, the first transport mechanism 10 also includes a tenth support plate 104 located at the movable end of the first XZ transfer module 101 and a first Y-axis transfer module 105 fixed on the tenth support plate 104. A ninth support plate 102 is located at the movable end of the first Y-axis transfer module 105. The first Y-axis transfer module 105 drives the second gripper module 103 on the ninth support plate 102 to achieve position adjustment in the Y direction, thereby ensuring that the center position of the stacks of solar cells 400 is always grasped.

[0047] The second handling mechanism 20 includes a second XZ transfer module 201, an eleventh support plate 202 disposed at the movable end of the second XZ transfer module 201, a sixth drive member 203 fixed on the eleventh support plate 202, a twelfth support plate 204 driven by the sixth drive member 203 to rotate around the Z-axis, and several third gripper modules 205 disposed on the twelfth support plate 204. The horizontal angle of the multiple battery cell stacks 400 can be adjusted by the sixth drive member 203 so that they can be accurately placed into the packaging box.

[0048] In this embodiment, since the spacing between the multiple battery cell stacks 400 in the battery cell detection mechanism 6 is different from the spacing between the multiple battery cell stacks 400 in the packaging box 500, the second conveying mechanism 20 further includes a spacing adjustment module 206 for adjusting the spacing between the multiple third gripper modules 205. The spacing adjustment module 206 can adopt a conventional spacing adjustment mechanism in the prior art, such as a motor-driven slide bar rotation, using the sliding groove on the surface of the slide bar to adjust the horizontal spacing between multiple objects. Since this mechanism is prior art, it will not be described in detail in this embodiment.

[0049] In other embodiments, if the spacing between the multiple cell stacks 400 in the cell detection mechanism 6 is the same as the spacing between the multiple cell stacks 400 in the packaging box 500, then there is no need to configure the spacing adjustment module 206.

[0050] The battery cell packaging and closing device 7 includes a box-standing positioning module 71 that supports the bottom of the packaging box and pushes the four baffles of the scattered packaging box into a standing state to form a baffle part B; a second X-axis transfer module 72 that drives the box-standing positioning module 71 to reciprocate between a first position and a second position along the X direction; a buffer removal and placement module 73 that removes the buffer from the packaging box 500 at the first position, puts the battery cells into the packaging box 500, and then puts the buffer back; a top cover module 74 that is positioned above the transfer path of the box-standing positioning module 71 and closes the top cover C of the packaging box 500 during the process of the box-standing positioning module 71 moving from the first position to the second position; a fourth camera 75 positioned above the first position; and a fifth camera 76 positioned above the second position.

[0051] The upright box positioning module 71 is driven by the second X-axis transfer module 72 to reciprocate between the first position and the second position. At the first position, the packaging box loading and conveying mechanism 4 places the packaging box 500 on the upright box positioning module 71; then the buffer removal and placement module 73 removes the intermediate buffer D2 inside the packaging box 500; the second conveying mechanism 20 puts multiple battery cell stacks 400 into the packaging box 500; at the second position, the packaging box 500 is operated to the latching state, and the packaging box carrying the battery cell stacks is removed by the third conveying mechanism 30 for subsequent labeling operations.

[0052] The sixth drive unit 203 in the second conveying mechanism 20 adjusts the angle and position of multiple battery cell stacks 400 based on the internal structure image information of the packaging box 500 obtained by the fourth camera 75, thereby ensuring that the multiple battery cell stacks 400 are accurately placed into their respective limiting grooves inside the packaging box.

[0053] The upright box positioning module 71 includes a support platform 711 that supports the bottom plate of the packaging box 500, several suction cups 712 that adsorb and fix the bottom plate of the packaging box onto the support platform 711, an upward pushing component 713 that is arranged around the support platform 711 and pushes the baffle of the packaging box upward, and a positioning component 714 that positions the packaging box on the support platform 711.

[0054] In this embodiment, the push-up assembly 713 is provided with four components respectively aligned with the four enclosure panels B1~B4, and each component includes an eighth cylinder 7131, a thirteenth support plate 7132 driven by the eighth cylinder 7131 to move up and down, and a plurality of pushing rollers 7133 disposed on the thirteenth support plate 7132. The push-up assembly 713 drives the pushing rollers 7133 to move upward through the eighth cylinder 7131, pushing the enclosure panels of the packaging box upward to an upright position.

[0055] The packaging box transitions from an open state to a formed state through the simultaneous action of multiple pushing components 713. However, if the packaging box 500 is not accurately positioned on the support platform 711 (e.g., biased towards one side or adjacent pushing components 713), the biased pushing component 713 may act on the bottom plate A, pushing it upwards. This can cause the packaging box 500 to be deformed or detach directly from the support platform 711. Therefore, before the pushing components 713 perform the forming operation on the packaging box, this embodiment includes a positioning component 714 to accurately position the bottom plate of the packaging box, ensuring reliable and effective subsequent forming of the packaging box. The positioning component 714 has four positions corresponding to the four vertices of the bottom plate of the packaging box, and includes a ninth cylinder 7141 and a positioning push rod 7142 driven by the ninth cylinder 7141 to move horizontally. When the packaging box 500 is placed on the support platform 711, it is in an open state. At this time, an L-shaped angle is formed between two adjacent baffles. By pushing the four positioning push rods 7142 forward into the L-shaped angle, the bottom plate of the packaging box can be accurately positioned by positioning the four vertices, while avoiding the working area of ​​the four upward push components 713. This satisfies both the positioning requirements of the bottom plate of the packaging box and the forming requirements of the packaging box baffles.

[0056] In this embodiment, since the top cover C is fastened to the outer side of the top of the baffle plate, after the baffle portion B of the packaging box is formed, the top of its baffle plates B2~B4 should preferably be slightly tilted towards the inside of the packaging box so that the top cover C can smoothly fasten the top of the baffle plate inside, thus closing the packaging box. Therefore, in order to achieve the above state, the eighth cylinder 7131 in this embodiment is tilted, driving the push roller 7133 to move obliquely upward, thereby pushing the baffle plate from the open state to the standing state while also tilting it towards the inside of the packaging box to a certain extent.

[0057] Furthermore, to accommodate the upward forming of packaging boxes of various specifications, this embodiment sets the tilt angle of the eighth cylinder 7131 to a convenient adjustable structure. Specifically, the upright box positioning module 71 also includes a first support frame 715, and the support platform 711, the upward pushing component 713, and the positioning component 714 are all mounted on the first support frame 715. A tilt angle adjustment component 716 is mounted on the first support frame 715, and the eighth cylinder 7131 is mounted on the movable end of the tilt angle adjustment component 716. The tilt angle adjustment component 716 includes a hinge seat 7161, a locking mounting seat 7162, and an adjusting support plate 7163; the hinge seat 7161 and the locking mounting seat 7162 are mounted on the first support frame 715, one end of the adjusting support plate 7163 is rotatably mounted on the hinge seat 7161, and the other end is locked and fixed to the locking mounting seat 7162 by a connecting block 7164, and the eighth cylinder 7131 is fixed to the adjusting support plate 7163. The tilt angle of the support plate 7163 can be adjusted by rotating it, thereby adjusting the angle of the eighth cylinder 7131 and adjusting the pushing effect of the pushing roller 7133 to meet the forming requirements of packaging boxes of different sizes.

[0058] After the packaging box 500 in its unfolded state is placed on the support platform 711, the top cover C is connected only by the baffle plate B1. Since the baffle plate B1 is tilted, the top cover C will also flip outwards. If the outermost edge of the top cover C flips outwards to below the bottom plate A, the packaging box 500 cannot effectively close the top cover C when it moves past the top cover module 74 with the upright box positioning module 71. To solve this technical problem, in this embodiment, the first support frame 715 is also provided with a top cover support rod 717 that supports the outer surface of the top cover C. By setting the top cover support rod 717 at a certain height and supporting the outer surface of the top cover C to prevent the outermost edge of the top cover C from flipping to below the bottom plate A, it is ensured that the top cover C can be effectively closed subsequently.

[0059] When the packaging box 500 receives the materials, it is equipped with several buffer components D inside. These buffer components D include a bottom buffer component (not shown in the figure) supporting the bottom of the cell stack, an outer buffer component D1 restricting the outermost positions of all cell stacks, and an intermediate buffer component D2 restricting the distance between two adjacent cell stacks 400. The bottom buffer component and the outer buffer component D1 are fixedly mounted on the base plate A, while the intermediate buffer component D2 can be removed from the packaging box 500. In this embodiment, there are two intermediate buffer components D2. When the materials arrive, the two intermediate buffer components D2 extend along the X direction. To facilitate the placement of the cell stack 400, the two intermediate buffer components D2 need to be removed. After the cell stack 400 is placed, it is rotated 90° and placed into the packaging box 500, that is, the two intermediate buffer components D2 extend along the Y direction and are placed between two adjacent cell stacks 400. Therefore, this embodiment achieves the above operation by setting up a buffer component handling module 73.

[0060] The buffer loading and unloading module 73 includes a second Y-axis transfer module 731, a second support frame 732 disposed at the movable end of the second Y-axis transfer module 731, a tenth cylinder 733 fixed on the second support frame 732, a fourteenth support plate 734 driven by the tenth cylinder 733 to move up and down, a rotary adsorption assembly 735 disposed on the fourteenth support plate 734 for adsorbing the angle of the rotating buffer, a prying assembly 736 disposed on the fourteenth support plate 734 for prying open the baffles on both sides of the packaging box in the X direction, and a plurality of pressing assemblies 737 disposed on the fourteenth support plate 734 for pressing the packaging box 500 downward onto the upright box positioning module 71.

[0061] The rotary adsorption assembly 735 includes an eleventh cylinder 7351 fixed to the lower surface of the fourteenth support plate 734, a twelfth cylinder 7352 driven by the eleventh cylinder 7351 to rotate around the Z-axis, a fifteenth support plate 7353 driven by the twelfth cylinder 7352 to move closer or further apart in the X-direction, and several third suction nozzles 7354 disposed on the fifteenth support plate 7353 for adsorbing the buffer members. By driving the two fifteenth support plates 7353 to move closer or further apart in the X-direction by the twelfth cylinder 7352, the distance between the two intermediate buffer members D2 can be adjusted to meet the pick-and-place requirements.

[0062] The actuating assembly 736 includes a nineteenth cylinder 7361 fixed above the fourteenth support plate 734, a sixteenth support plate 7362 driven by the nineteenth cylinder 7361 to move up and down, a thirteenth cylinder 7363 disposed on the sixteenth support plate 7362 and located on both sides of the rotating adsorption assembly 735 in the X direction, and an actuating plate 7364 driven by the thirteenth cylinder 7363 to move in the X direction. An avoidance slot (not shown in the figure) is provided on the outer buffer member D1 to avoid the actuating plate 7311.

[0063] Four sets of clamping components 737 are provided, aligned with the four corner areas of the bottom plate of the packaging box. Each clamping component 737 includes a fourteenth cylinder 7371 fixed to the fourteenth support plate 734 and a pressure rod 7372 driven by the fourteenth cylinder 7371 to move up and down. Since the intermediate buffer D2 is sandwiched in the grooves of the two bottom buffers, it has a certain frictional force. The clamping components 737 can prevent the packaging box 500 from being lifted and displaced when picking up the buffers. However, since the bottom plate of the packaging box is attracted and fixed by the suction cup 712 on the support platform 711, the possibility of the bottom plate being lifted upwards is low. In some embodiments, the clamping components 737 can be configured for safety reasons; in other embodiments, the clamping components 737 may not be provided.

[0064] After the packaging box 500 is placed on the support platform 711 in the upright box positioning module 71 and positioned, the second Y-axis transfer module 731 drives all the structures on the fourteenth support plate 734 to move above the packaging box (i.e. above the first position). All the clamping components 737 are activated to press down on the four corner areas of the bottom plate of the packaging box (avoiding the bottom buffer) to prevent the packaging box 500 from being lifted and moved upward when picking up the buffer. Then, the toggle component 736 is activated to pry open the two baffles in the X direction of the packaging box to prevent the two baffles from obstructing the picking up and putting down of the intermediate buffer D2. After that, the rotating adsorption component 735 adsorbs the intermediate buffer D2, and the fourteenth support plate 734 moves upward to pick up the intermediate buffer D2. Afterwards, the rotating adsorption assembly 735 on the fourteenth support plate 734 takes the intermediate buffer D2 back to the avoidance position and rotates the intermediate buffer D2 90°. After the battery cell stack is placed in the packaging box, the intermediate buffer D2 is put back into the packaging box 500, completing the return of the intermediate buffer D2.

[0065] The top cover module 74 is positioned above the transfer path of the box-standing positioning module 71 driven by the second X-axis transfer module 72, and includes a column 741, a height adjustment component 742 mounted on the column 741, a twenty-second support plate 743 located at the movable end of the height adjustment component 742, and several downward pressure rollers 744 elastically floating below the twenty-second support plate 743. The height adjustment component 742 can be an automatic transfer module or a handwheel adjustment mechanism. When the packaging box 500 is placed on the box-standing positioning module 71, the baffles B1 and B3 need to be distributed in the X direction, and the baffle B1 connecting the top cover C needs to be located on the side closer to the labeling mechanism 8. In this way, as the packaging box 500 passes the top cover module 74 along the X direction with the box-standing positioning module 71, the downward pressure rollers 744 can constrain the top cover C from the open state to the closed state, resulting in the package 600.

[0066] After the second X-axis transfer module 72 drives the upright box positioning module 71 to move the packaging box 500 and the battery cell stack 400 to the second position, the fifth camera 76 detects whether the packaging box 500 is properly closed.

[0067] The labeling mechanism 8 is located on the X-direction moving path of the package 600 carried by the third conveying mechanism 30, and includes a label supply module 81, a labeling module 82 that takes out the label from the label supply module 81 and sticks it onto the package 600, and a rolling module 83 that rolls the label on the package 600 firmly.

[0068] The label supply module 81 can use an online printer for printing or a feeder for feeding. In this embodiment, an online printer is used for label printing.

[0069] The labeling module 82 includes a third Y-axis transfer module 821, a seventeenth support plate 822 driven by the third Y-axis transfer module to move along the Y direction, a fifteenth cylinder 823 fixed on the seventeenth support plate 822, an eighteenth support plate 824 driven by the fifteenth cylinder 823 to rotate around the Z-axis, a sixteenth cylinder 825 fixed on the eighteenth support plate 824, and a label-absorbing block 826 driven by the sixteenth cylinder 825 to rotate around the X-axis. The label orientation on the label-absorbing block 826 is adjusted by the fifteenth cylinder 823 and the sixteenth cylinder 825.

[0070] The rolling module 83 includes a seventeenth cylinder 831, an eighteenth cylinder 832 driven by the seventeenth cylinder 831 to move in the Y direction, a nineteenth support plate 833 driven by the eighteenth cylinder 832 to move up and down, and a second rolling roller 834 disposed on the nineteenth support plate 833. Labels are affixed to a designated lateral surface on the outer periphery of the package 600 by the labeling module 82, and then the rolling module 83 firmly rolls the labels.

[0071] The third handling mechanism 30 includes a third XZ transfer module 301, a twentieth support plate 302 disposed at the movable end of the third XZ transfer module 301, a seventh drive member 303 fixed on the twentieth support plate 302, a twentieth support plate 304 driven by the seventh drive member 303 to rotate around the Z-axis, and a fourth gripper module 305 disposed on the twentieth support plate 304 for gripping the package 600.

[0072] The unloading device 9 includes a finished product unloading conveyor line 91 that conveys the package 600 along the X direction. The conveying end of the finished product unloading conveyor line 91 extends to one side of the production line in the X direction and is located on the same side of the production line as the conveying beginnings of the cell stack feeding conveyor line 1 and the packaging box feeding conveyor line 2. This ensures that the cell stack feeding end, the packaging box feeding end, and the finished product receiving end are all located on the same side of the production line, thus preventing confusion in loading and unloading.

[0073] However, if defects are detected in the preceding workstations, such as the cell counting mechanism 5 or the cell inspection mechanism 6, they need to be discharged. The cell stack 400 after the cell inspection mechanism 6 lacks external packaging, leaving its perimeter unconstrained. Direct discharge of these cells could easily cause the stack to collapse and scatter. To address this problem, this embodiment designs the discharge of defective cell stacks 400 on the finished product unloading conveyor line 91. Specifically, the unloading device 9 includes a defective product unloading conveyor line 92 located below the finished product unloading conveyor line 91 and conveying materials along the Y direction; a second lifting module 93 located at the end of the finished product unloading conveyor line 91 and connecting the finished product unloading conveyor line 91 and the defective product unloading conveyor line 92; and a first pushing module 94 that pushes defective packages from the finished product unloading conveyor line 91 onto the second lifting module 93. The second lifting module 93 includes a lifting drive assembly 931 and a conveying assembly 932 driven by the lifting drive assembly 931 to move up and down and convey materials along the Y direction.

[0074] When a defect is detected in the cell counting mechanism 5 or the cell testing mechanism 6, the defect cause information is transmitted to the labeling mechanism 8. The subsequent packaging and labeling actions are still performed. The defective cells are packaged in a packaging box 400 to obtain a defective package. The labeling mechanism 8 outputs a label with the defect cause information and affixes it to the defective package. Subsequently, the defective product is removed from the finished product unloading conveyor line 91 by the first push module 94 and sent to the defective product unloading conveyor line 92. The defective product is then unloaded through the defective product unloading conveyor line 92.

[0075] Since there are two production units in this embodiment (i.e., the first production unit 200 and the second production unit 300), two feeding devices 9 are formed accordingly. The two feeding devices 9 will have two defective product output ports. In order to integrate the two defective product output ports of the two feeding devices 9 into one place for centralized feeding, the second lifting module 93 in this embodiment has Y1 side and Y2 side that are relatively distributed in the Y direction. One end of the defective product feeding conveyor line 92 in one of the production units is connected to the Y2 side of the second lifting module 93 in that production unit, and the other end is connected to the Y1 side of the second lifting module 93 in another production unit. Therefore, the defective product feeding conveyor lines 92 in the two production units are connected in series and the defective packages are output from a unified port. The output end of the series defective product feeding conveyor line 92 extends to the Y direction side of the production line.

[0076] A sixth camera (not shown in the figure) is also installed above the conveying path of the packaging box feeding conveyor line 2 to detect defects in the packaging boxes 500. If the packaging box 500 is found to be non-compliant, it needs to be discharged. In order to realize the recycling of defective packaging boxes 500, the first production unit 200 and the second production unit 300 in this embodiment of the production line also include a packaging box recycling and unloading device 50. The packaging box recycling and unloading device 50 includes a first packaging box recycling conveyor line 501 that conveys materials in the X direction, a second packaging box recycling conveyor line 502 located at the end of the first packaging box recycling conveyor line 501 and conveying materials in the Y direction, and a second pushing module 503 that pushes the packaging boxes from the first packaging box recycling conveyor line 501 to the second packaging box recycling conveyor line 502. The first packaging box recycling conveyor line 501 is arranged parallel to the Y-direction side of the packaging box feeding conveyor line 2 and its first end extends to the bottom of the packaging box loading and handling mechanism 4.

[0077] In this embodiment, a seventh camera (not shown in the figure) is also installed above the conveying path of the cell stack feeding conveyor line 1 to detect whether the number of cell stacks inside the cell cassette 700 is correct or whether the orientation of the cell cassette is correct. If an NG condition is detected, the cell stack needs to be discharged. Therefore, the production line in this embodiment also includes a cell cassette recycling conveyor line 60 that is vertically connected to the cell stack feeding conveyor line 1, and a third pushing module 70 that pushes the cell cassette 700 from the cell stack feeding conveyor line 1 to the cell cassette recycling conveyor line 60. The cell cassette recycling conveyor line 60 conveys materials along the Y direction and its output end extends to the Y direction side of the production line. The output end of the cell cassette recycling conveyor line 60 is located close to the defective product output end of the defective product unloading conveyor line 92 to achieve centralized unloading of defective products.

[0078] In this embodiment, firstly, the beginning of the cell stack feeding conveyor line 1, the beginning of the packaging box feeding conveyor line 2, the output end of the finished product unloading conveyor line 91 in the unloading device 9, and the end of the box return conveyor line 11 all extend to the same side of the X direction of the entire production line, so that operators or AGVs can perform cell box replenishment, empty cell box recycling, packaging box replenishment, and finished product unloading on the same side of the X direction of the production line. Secondly, defective packaging boxes are output from both sides of the Y direction of the production line through the first packaging box recycling conveyor line 501 and the second packaging box recycling conveyor line 502; defective cell boxes are also output from one side of the Y direction of the production line through the cell box recycling conveyor line 60; and defective cell stacks are loaded into packaging boxes to form defective packages, which are output from one side of the Y direction of the production line through the defective product unloading conveyor line 92. This allows operators or AGVs to unload defective packaging boxes, defective packages, and defective cell boxes on one or both sides of the Y direction of the production line. In summary, this embodiment integrates various locations such as the cell feeding box, empty cell feeding box recycling location, packaging box feeding location, finished product receiving location, defective packaging box recycling location, defective packaging unloading location, and defective cell feeding box unloading location, facilitating material replenishment and recycling on the production line. Furthermore, it clearly separates the good product unloading location (on the X side of the production line) from the defective product unloading location (on one or both sides of the Y direction of the production line), effectively avoiding confusion in the feeding and unloading of various materials.

[0079] This embodiment also provides a production method for a battery cell testing, boxing, and packaging production line, which includes: S1, the cell stack feeding conveyor line 1 conveys the cell material box 700, which is loaded with multiple cell stacks 400, to the end in the reverse direction along X; S2. The battery cell loading and handling mechanism 3 takes out all the battery cell stacks 400 in the battery cell material box 700 on the battery cell stack feeding conveyor line 1 and places them on the battery cell counting mechanism 5 in the first production unit 200 or the second production unit 300. S3, the cell counting mechanism 5 simultaneously performs cell counting detection on multiple cell stacks of 400; S4. The first conveying mechanism 10 conveys multiple stacks of solar cells 400 from the solar cell counting mechanism 5 to the solar cell testing mechanism 6. S5, the cell inspection unit 6 simultaneously performs defect inspection on multiple cell stacks 400; S6. During the execution of S1~S5, the packaging box feeding conveyor 2 transports the packaging box 500 in the closed state to the end in the reverse direction of X, and uses the box opening and transfer mechanism 40 to operate the packaging box 500 to the open state; the packaging box loading and handling mechanism 4 transports the open packaging box to the battery cell boxing and closing device 7. S7. The second conveying mechanism 20 conveys multiple battery cell stacks 400 from the battery cell detection mechanism 6 to the battery cell packaging and closing device 7, and, with the assistance of visual positioning, places the multiple battery cell stacks 400 into the packaging box 500. The packaging box 500 containing the multiple battery cell stacks 400 is then closed by the battery cell packaging and closing device 7, resulting in a package 600. Specifically, the open packaging box 500 is placed on the upright positioning module 71, and the buffer component removal and placement module 73 removes the buffer component from the packaging box 500. Under the visual positioning of the fourth camera 75, the conveying mechanism 20 places multiple battery cell stacks 400 into designated positions within the packaging box 500. The buffer component placement module 73 then places the buffer component into the packaging box 500 according to the set posture and position. The second X-axis transfer module 72 drives the upright positioning module 71 to move the packaging box 500 and the battery cell stacks 400 together through the top cover module 74. The top cover module 74 constrains the packaging box 500 to a closed state, and the fifth camera 76 detects whether the packaging box is closed correctly, thus obtaining the package 600. S8, the third conveying mechanism 30 conveys the package 600 from the battery cell boxing and closing device 7 through the labeling mechanism 8, outputs a label through the labeling mechanism 8 and affixes the label to the designated position on the package 600; S9, the third handling mechanism 30 handles the packaged item 600 and continues to move it to the unloading device 9. If the tests in S3, S5 and S7 are all qualified, the item is output through the finished product unloading conveyor line 91; otherwise, the item is output through the defective product unloading conveyor line 92.

[0080] This embodiment presents a battery cell testing, boxing, and packaging production line 100 and its production method, which is a highly integrated, intelligent, flexible, efficient, and reliable fully automated solution for the back-end processing of battery cells. It not only improves efficiency through parallel processing and optimized cycle time, but also solves several specific process challenges through a series of ingenious mechanical and vision designs. Furthermore, it achieves orderly management of the production site through excellent logistics planning. The overall technology is advanced, possessing significant practical value and promotional significance. It has the following advantages: (1) High efficiency and high cycle time are achieved: By setting up two parallel production units (first production unit 200 and second production unit 300), the production capacity is doubled; within each production unit, the processes of counting, testing, and boxing of battery cells support the parallel processing of multiple stacks (such as three), which greatly improves the single-machine processing capacity; multi-axis robots are used for battery cell stack loading, with a large range of motion and high speed, which meets the loading cycle time requirements of four battery cell counting mechanisms 5 and overcomes the bottleneck process limitations.

[0081] (2) A compact spatial layout was achieved: the handling mechanism (first, second and third handling mechanism) was arranged on the outermost side of the Y direction, and the core process equipment (counting, testing and boxing mechanism) was concentrated in the middle installation space, which shortened the width of the production line in the Y direction; the battery cell loading robot was arranged above the feeding line, and the length of the production line in the X direction was greatly shortened by utilizing the Z direction space, which reduced the ground area occupied.

[0082] (3) High precision and high reliability were achieved: A unique “bar blocking” automatic box opening method and mechanism were designed, which successfully solved the problem of opening special packaging boxes and was stable and reliable; The battery cell detection mechanism 6 adopts a combination scheme of adjustable vision module position and independent lifting of the bearing seat to ensure that each battery cell stack and each surface to be inspected can obtain a clear image and high detection accuracy; Before the packaging box is formed, the positioning push rod is inserted into the L-shaped angle for precise positioning to prevent the box from being deformed; The angle of the upward push cylinder is adjustable to adapt to different boxes and ensure that the top of the enclosure is slightly tilted inward, which is conducive to closing the lid.

[0083] (4) It achieves strong adaptability and flexibility: the battery cell feeding and handling mechanism integrates the spacing adjustment function, which can adapt to different cell stack spacings between the material box and the work station; the first handling mechanism adds a Y-axis transfer module, which can automatically adjust the gripping position to adapt to the center gripping requirements of battery cell stacks of different lengths; the packaging box feeding mechanism is equipped with a side push module, which can actively push outwards the baffles that may not be completely dispersed to ensure the reliability of the suction.

[0084] (5) It realizes orderly material flow and intelligent management: the inlet (battery cell, packaging box supply) and outlet (finished product unloading) of all good materials are centrally located on the same side of the X direction of the production line, which facilitates centralized operation and management; the recycling outlets of all defective products and empty boxes (defective packaging, defective packaging box, empty battery cell box) are guided to one or both sides of the Y direction of the production line, completely separated from the good product flow line, to avoid confusion; the defective battery cell pile is packaged first, then labeled (record defective information), and then removed, which solves the problem of easy scattering of waste without packaging and realizes traceable management of defective products.

[0085] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
