Then, the guide structure of the battery cell insertion execution structure guides the outer casing to slide towards the battery cell (in the axial direction of the central axis) and slowly approach the battery cell until part of the battery cell enters the outer casing. Finally, the pressing structure of the battery cell insertion execution structure pushes the outer casing to completely enclose the outer casing within the battery cell, thus completing the battery cell insertion. During this process, the battery cell does not need to be moved, allowing it to remain on the original transport device during insertion. After insertion, the battery cell does not need to be transferred back to the transport line. By realizing dynamic battery cell insertion, the efficiency of battery cell insertion can be greatly improved. Attached Figure Description

[0049] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0050] This application proposes a cell housing system, see attached document. Figures 1 to 3 As shown, the main components of the battery cell insertion system proposed in this application include a first conveying device, a second conveying device, and an insertion execution structure. The insertion execution structure includes a clamping and alignment structure, a guiding structure 5, and a pressing structure 6. The main implementation method of battery cell insertion is as follows: the battery cell 7 is conveyed on the first conveying device. During the conveying of the battery cell 7, the outer casing 8 is conveyed to the vicinity of the battery cell 7 by the second conveying device. The relative stillness of the outer casing 8 and the battery cell 7 is maintained by controlling the conveying speed of the second conveying device to be the same as that of the first conveying device and ensuring that the conveying direction of the outer casing 8 is the same as that of the battery cell 7. The clamping and alignment structure of the insertion execution structure presses the battery cell 7 and the outer casing 8 together to ensure that they are close to each other. The outer casing 8 is aligned so that the battery cell 7 and the outer casing 8 are on the same central axis. Then, the guide structure 5 of the casing insertion execution structure guides the outer casing 8 to slide towards the battery cell 7 (in the axial direction of the central axis) and slowly approach the battery cell 7 until part of the battery cell 7 enters the outer casing 8. Finally, the pressing structure 6 of the casing insertion execution structure pushes the outer casing 8 to completely cover the battery cell 7, thus completing the battery cell insertion. During this process, the battery cell 7 does not need to be moved, so that the battery cell 7 remains on the original conveying equipment when it is inserted into the casing. After the battery cell is inserted into the casing, it is not necessary to transfer the battery cell 7 back to the conveying line. By realizing the dynamic insertion of the battery cell 7 into the casing, the efficiency of battery cell insertion into the casing can be greatly improved.

[0051] The following section will provide a detailed description of the cell housing system.

[0052] In one embodiment, the first conveying device includes a first conveyor line 20 and a first carrier disposed on the first conveyor line 20. The battery cell 7 is fixed on the first carrier, thereby being conveyed on the first conveyor line 20 by the first carrier. The battery cell 7 is conveyed to various workstations via the first conveyor line 20, and does not stop at the workstation where the battery cell is inserted into the casing. The second conveying device includes a second conveyor line 10 and a plurality of second carriers disposed on the second conveyor line 10. The spacing between the first carriers is the same as the spacing between the second carriers. A tooling fixture 100 is disposed on the second carrier. The tooling fixture 100 includes a casing fixing component, which is used to pick up the casing 8 and assist in guiding the battery cell 7 into the casing 8. A first section is disposed on the first conveyor line 20, and a second section is disposed on the second conveyor line 10. The first section and the second section are positioned opposite each other and parallel to each other. Thus, when controlling the casing 8 and the battery cell 7 to be relatively stationary, only the conveying speed and direction of the conveyor line need to be considered.

[0053] Preferably, in this application, the second conveyor line 10 is configured as a circular conveyor line, so that the second carrier can circulate on the conveyor line. The second conveyor line 10 includes a third section, and a shell loading mechanism is provided on the outside of the third section, such as... Figure 2 As shown, the outer casing loading mechanism includes an outer casing storage bin for storing outer casings 8. The outer casing loading mechanism is also equipped with a set of robotic arms 302. The robotic arms 302 sequentially pick up the outer casings 8 and transfer them to the conveyor line in an orderly manner. The outer casings 8 are conveyed to the loading position 303 by the conveyor line. The loading position 303 corresponds to the third section of the second conveyor line 10. When the second carrier passes the loading position 303, the tooling fixture 100 directly picks up the outer casings 8 on the loading position 303. In this way, the outer casings 8 are picked up in a cyclic manner. There is no need to stop loading during the assembly gap between the outer casings 8 and the battery cells 7, so as to achieve efficient assembly of the outer casings 8 and the battery cells 7.

[0054] Of course, in other embodiments, the outer casing 8 can also be transported in a conventional manner. For example, the second transport device is an industrial robot. Multiple industrial robots are set up to directly take the outer casing 8 from the outer casing storage compartment and transfer the outer casing 8 above the battery cell 7. When the industrial robot senses that there is a battery cell 7 below and the outer casing 8 and the battery cell 7 are aligned and close to each other, the industrial robot can carry the outer casing 8 at the same speed and in the same direction as the first transport line 20, thereby keeping the outer casing 8 and the battery cell 7 relatively stationary.

[0055] It should be noted that, in addition to the methods exemplified above, countless other implementation methods can be found in the prior art for those skilled in the art for the second conveying device. This application cannot exhaustively list all methods, and directly applying the common shell 8 conveying methods in the prior art to this application also falls within the scope of this application.

[0056] Furthermore, the relative positions of the first conveyor line 20 and the second conveyor line 10 can be adaptively selected according to the customer's choice. In this embodiment, the first conveyor line 20 is set below the second conveyor line 10, that is, the first section is located directly below the second section. The conveying direction and conveying speed of the second section parallel to the first section are the same. Since the second conveyor line 10 is circular in shape, when designing, it is only necessary to align one of the second carriers with the first carrier to ensure that the conveying direction and conveying speed of the first conveyor line 20 and the second conveyor line 10 are the same, which can ensure the alignment of each subsequent second carrier with the first carrier.

[0057] Once the outer casing 8 and the battery cell 7 are aligned, the core insertion step can be performed by the casing insertion execution structure. Based on the positional relationship between the first conveying line 20 and the second conveying line 10 in the above embodiment, this application further proposes a corresponding casing insertion execution structure.

[0058] Specifically, see the appendix. Figures 4 to 8 As shown, the housing insertion execution structure in this application integrates a holding and alignment structure, a guiding structure, a pressing structure, and the tooling fixture. The housing insertion execution structure includes an alignment part, into which the housing and the battery cell are simultaneously fed, maintaining their approximate coaxial alignment. The alignment part can be a chamber with a limiting function, allowing the housing and battery cell to be simultaneously fed into the alignment part, thus placing them within a specific range. The clamping and alignment structure then performs a more accurate alignment operation. In this embodiment, the alignment part and the clamping and alignment structure are integrated; that is, the clamping and alignment structure can perform clamping and alignment, and also has a limiting function. Specifically, the clamping and alignment structure consists of a first clamping and alignment structure 1, a second clamping and alignment structure 2, a driving component 3, a guiding structure 5, and a pressing structure 6. The device consists of a first clamping and alignment structure 1 for clamping the battery cell 7 and a second clamping and alignment structure 2 for clamping the outer casing 8. The clamping centers of the first clamping and alignment structure 1 and the second clamping and alignment structure 2 are kept coaxial. When no clamping action is performed, the clamping centers of the first clamping and alignment structure 1 and the second clamping and alignment structure 2 are the alignment parts. The driving component 3 drives the first clamping and alignment structure 1 and the second clamping and alignment structure 2 to perform clamping actions synchronously, thereby clamping the battery cell 7 and the outer casing 8 and keeping them aligned. The guiding structure 5 is used to guide the first clamping and alignment structure 1 and the second clamping and alignment structure 2 to slide towards each other, thereby guiding the battery cell 7 and the outer casing 8 to move closer together. After the battery cell 7 and the outer casing 8 are aligned and close together, the pressing structure 6 sends the battery cell 7 into the outer casing 8, completing the entire action of inserting the battery cell into the casing.

[0059] The guide structure 5 mainly includes a fixed bracket 51 and a movable bracket 53. The fixed bracket 51 is used to support and fix the tooling fixture on the second conveyor line 10, which is used to perform the step of inserting the battery cell into the casing. The second conveyor line 10 is, for example, a robotic arm or a conveyor carrier. The movable bracket 53 is slidably connected to the fixed bracket 51. That is, the fixed bracket 51 is used to fix the tooling fixture, and the movable bracket 53 slides on the fixed bracket 51. It can be used to perform actions such as clamping, aligning and assembling the battery cell 7 and the casing 8.

[0060] Furthermore, the movable bracket 53 includes a base plate 54, and the second clamping and alignment structure 2 is installed at the lower end of the base plate 54. An alignment opening is provided in the middle of the base plate 54. The fixed bracket 51 includes a fixing plate 52, which is parallel to the base plate 54 and is positioned above the base plate 54. A suction cup assembly 61 (i.e., a housing fixing assembly; in other embodiments, a gripper or other fixing mechanism can be used instead of the suction cup assembly) is also provided on the fixed bracket 51. The suction cup assembly 61 uses a vacuum machine to draw a vacuum to pick up the housing 8. The suction cup assembly 61 is positioned opposite to the alignment opening, thereby gripping the housing 8 to the alignment opening. In this embodiment, the fixing plate 52 is fixed on the carrier, thereby used to transport the tooling fixture 100 to the top of the battery cell 7. The press-fit structure 6 includes a telescopic drive device, which includes a push rod. In this embodiment, the telescopic drive device and the suction cup assembly 61 are designed as a single unit, that is, the suction cup assembly 61 is set on the telescopic end of the push rod. The telescopic drive device pushes the suction cup assembly 61 to move up and down. The telescopic drive device is the power drive unit for pushing the core into the shell. After the second clamping alignment structure 2 and the first clamping alignment structure 1 clamp and align the shell 8 and the battery cell 7 respectively, the telescopic drive device pushes the shell 8 to be fitted onto the battery cell 7.

[0061] Furthermore, an upper extension plate 541 perpendicular to the base plate 54 is provided above the base plate 54 of the fixed bracket 51, and a lower extension plate 521 perpendicular to the fixed plate 52 is provided below the fixed plate 52 of the movable bracket 53. The upper extension plate 541 and the lower extension plate 521 are in contact with each other. By setting a set of slide rails on the upper extension plate 541 and a slider on the lower extension plate 521, the upper extension plate 541 and the lower extension plate 521 can slide relative to each other up and down.

[0062] The guide structure 5 also includes a first guide component 55 connecting the first clamping alignment structure 1 and a second guide component 56 connecting the second clamping alignment structure 2. The first guide component 55 and the second guide component 56 are slidably connected to drive the battery cell 7 and the outer casing 8 to move closer together again. Specifically, the battery cell 7 and the outer casing 8 are rectangular in shape. To better achieve clamping alignment of the battery cell 7 and the outer casing 8, a clamping body needs to be provided on all four sides of the battery cell 7 and the outer casing 8 to clamp them. For ease of understanding, this application uses the clamping body on one side of the battery cell 7 and the outer casing 8 as an example. The second clamping alignment structure 2 includes a second clamping body 21, which is located on one side of the battery cell 7 in the horizontal direction. The second clamping body 21 is the main body that performs the clamping action. The alignment structure 1 includes a first clamping body 11 disposed on one side of the battery cell 7 in the horizontal direction. The first clamping body 11 is used to perform clamping and centering of the battery cell 7. The first clamping body 11 and the second clamping body 21 are located on the same side of the battery cell 7. The first clamping body 11 and the second clamping body 21 are slidably connected by a first guide component 55 and a second guide component 56. The first guide component 55 can be a linear slide rail fixed on the first clamping body 11, and the second guide component 56 can be a slider fixed on the first clamping body 11. The second guide component 56 slides linearly on the first guide component 55. Since the slide rail is fixed on the first clamping body 11, when the second clamping body 21 slides, it will slide towards the first clamping body 11, so that the outer shell 8 and the battery cell 7 are close to each other.

[0063] Furthermore, the casing execution structure also includes a linkage structure 9, which is integrated with the tooling fixture 100. The linkage structure 9 includes a first linkage rod 91, the upper end of which is fixedly connected to the lower end of the second clamping body 21. The lower end of the first linkage rod 91 faces the first clamping body 11, and the first clamping body 11 is provided with a first through hole 92 for the first linkage rod 91 to slide through. The first linkage rod 91 is engaged with the lower end of the second clamping body 21 on the outside of the first through hole 92, which limits the extreme position of the sliding of the first clamping body 11 and the second clamping body 21. The drive assembly 3 pushes the first linkage rod 91 to move horizontally toward the battery cell 7 and the outer casing 8. By driving the drive device 31, the first clamping body 11 and the second clamping body 21 can be driven synchronously to perform clamping actions.

[0064] Furthermore, an elastic reset member 93 is provided between the first clamping body 11 and the second clamping body 21. The elastic reset member 93 is a spring, which is fitted on the first linkage rod 91. The upper end of the spring abuts against the second clamping body 21, and the lower end of the spring abuts against the first clamping body 11. When the first clamping body 11 and the second clamping body 21 are subjected to force and slide towards each other, after the battery cell 7 and the outer shell 8 are assembled, the first elastic reset member 93 will spring the first clamping body 11 and the second clamping body 21 apart.

[0065] Furthermore, the linkage structure 9 also includes a sleeve 94 and a second connecting rod 96. The sleeve 94 is mounted and fixed on the fixing plate 52. The sleeve 94 is hollow, and the second connecting rod 96 is disposed in the sleeve 94 and extends to the lower end of the sleeve 94. The second connecting rod 96 slides up and down in the sleeve 94 to realize the extension and retraction of the second connecting rod 96. A pair of oppositely arranged sliding grooves 95 are provided on the sleeve 94, and the sliding grooves 95 extend perpendicular to the horizontal direction. The second connecting rod 96 is provided with a sliding groove... The moving part 97 and the sliding part 97 extend through the sliding groove 95 to the outside of the sleeve 94. A transmission plate 98 is also provided on the base plate 54. The transmission plate 98 abuts against the lower end of the sliding part 97. The lower end of the second linkage rod 96 is provided with a socket 962. The first clamping body 11 is also provided with a plate 111 that passes through the socket 962 to restrict the first clamping body 11 from sliding further downward. When the movable bracket 53 slides downward, it simultaneously drives the first clamping body 11 and the second clamping body. 21 slides downwards, the first clamping body 11 falls to both sides of the battery cell 7 until the sliding member 97 abuts against the bottom of the lower groove of the sliding groove 95, preventing the second linkage rod 96 and the sleeve 94 from disengaging. At this time, the first clamping body 11 slides to its limit position and stops sliding downwards. However, the second clamping body 21 continues to slide downwards with the movable bracket 53. Under the clamping of the second clamping body 21, the outer shell 8 continues to move towards the battery cell 7 and compress the elastic reset member 93. When the outer shell 8 is partially fitted onto the battery cell 7, the second linkage rod 96... The first clamping alignment structure 1 and the second clamping alignment structure 2 simultaneously release the outer shell 8 and the battery cell 7. The telescopic drive device continues to push the outer shell 8 downward until the battery cell 7 is completely inserted into the outer shell 8. After the battery cell 7 and the outer shell 8 are assembled, the movable bracket 53 slides upward, and the transmission plate 98 abuts against the sliding member 97, causing the second linkage rod 96 to slide upward synchronously. The second linkage rod 96 then drives the first clamping body 11 to slide upward. At the same time, the elastic reset member 93 elastically resets, and the first clamping body 11 and the second clamping body 21 are popped apart.

[0066] Furthermore, a rolling bearing 961 is provided at the lower end of the socket 962. The insert plate 111 is in contact with the rolling bearing 961. Thus, when the drive device 31 drives the first clamping body 11 to perform a clamping action, the insert plate 111 slides in the socket 962. The rolling bearing 961 assists the insert plate 111 in sliding, reducing the sliding friction between the insert plate 111 and the socket 962.

[0067] Furthermore, this application also includes a power input component for sliding the movable support 53 and / or the second clamping alignment structure 2.

[0068] In this embodiment, refer to the appendix. Figure 2 , 3As shown in Figure 9, in the first embodiment, the power input component includes a guide rail 101 on a second conveyor line and a pulley 1001 on a tooling fixture. The pulley 1001 is mounted on the guide rail 101, which is used to define a specific running trajectory for the tooling fixture. The guide rail 101 mainly includes a first horizontal section 102, a first transition section 103, a second horizontal section 104, and a second transition section 105. The first horizontal section 102 and the second horizontal section 104 are both horizontally positioned, and the first horizontal section 102 is higher than the second horizontal section 104. The first transition section 103 connects the first horizontal section 102 to the second horizontal section 104, while the second transition section 105 connects the second horizontal section 104 to the first horizontal section 102. A height difference is formed between the first horizontal section 102 and the second horizontal section 104, so that... When the tooling fixture moves from the first horizontal section 102 to the second horizontal section 104, it falls downwards. The battery cell is located below the second conveyor line. When the tooling fixture moves downwards, the relative distance between the battery cell and the tooling fixture decreases, and the alignment part aligns with the battery cell. By setting a height difference in the guide rail 101, the height of the tooling fixture is reduced, so that the alignment part of the tooling fixture automatically moves down onto the battery cell, so that the battery cell is sent into the alignment part in the second horizontal section 104. In this way, there is no need to transfer the battery cell, which greatly improves the efficiency of battery cell insertion. During alignment, the tooling fixture moves while the battery cell does not move, which eliminates the risk of damage to the fragile internal structure of the battery cell. Moreover, the overall structure is simple to implement. The sliding path of the pulley 1001 on the guide rail 101 can remain stable for a long time, so it is not easy to cause the problem of deterioration of alignment accuracy. The cost of later maintenance and repair is extremely low.

[0069] Furthermore, the first transition section 103 is stepped, comprising a first inclined section 1031, a third horizontal section 1032, and a second inclined section 1033 connected sequentially. The height of the third horizontal section 1032 is between the first horizontal section 102 and the second horizontal section 104. This avoids aligning the tooling fixture in one step, but rather adopts a phased descent method. First, the tooling fixture falls to the height of the third horizontal section 1032, at which point the distance between the tooling fixture and the battery cell is closer, and part of the battery cell enters the alignment part, while the outer shell is fixed in the alignment part. In this way, even if there is a certain error in the coaxiality between the battery cell and the outer shell, it can be improved in this step, reducing the error in coaxiality between the battery cell and the outer shell. After passing through the second inclined section 1033, the tooling fixture enters the second horizontal section 104, at which point the height of the tooling fixture decreases further, the gap between the battery cell and the outer shell decreases further, and the battery cell can partially enter the outer shell, achieving the pre-positioning of the battery cell and the outer shell. Finally, in one step, the outer shell is directly pushed onto the battery cell. By setting the first transition section 103 in a stepped shape, the height of the tooling fixture can be reduced in stages. The battery cell is first sent into the alignment part, and then a part of the battery cell is sent into the housing. This avoids the defect of damaging the battery cell structure caused by one-time alignment and installation, and improves the assembly quality of battery cell installation.

[0070] The second transition section is for the tooling fixture to detach from the battery cell. The tooling fixture rises through the second transition section, causing the battery cell and the housing assembled by the alignment part to separate from each other. The assembled battery cell and housing continue to the next step, while the tooling fixture can cyclically pick up the next housing and perform the next battery cell insertion.

[0071] Furthermore, in this application, the battery cell 7 is disposed on the first conveyor line 20, and the first conveyor line 20 is located below the second conveyor line 10, with the second conveyor line 10 and the first conveyor line 20 partially overlapping. This ensures that the battery cell 7 is continuously conveyed on the first conveyor line 20. The tooling fixture 100 moves synchronously with the battery cell 7, thereby completing the battery cell casing operation in the area where the second conveyor line 10 and the first conveyor line 20 overlap. This greatly improves the battery production efficiency.

[0072] Preferably, the second conveyor line 10 in this application includes two parallel guide rails 101 arranged at the top and bottom, and the tooling fixture 100 includes two sets of rollers, each set of rollers being arranged in a guide rail 101. This ensures that the tooling fixture 100 will not vibrate when it descends, thus improving the accuracy of the battery cell insertion.

[0073] In addition to the above methods, the power input component can also directly use a power drive device 31, such as a cylinder, electric actuator, drive motor, etc.

[0074] The working principle of this embodiment is as follows: The tooling fixture 100 is installed on the second conveyor line 10. The second conveyor line 10 synchronously drives the tooling fixture. First, the suction cup assembly 61 grabs the outer shell 8 to the alignment port. Then, the second conveyor line 10 continues to drive the outer shell 8 above the battery cell 7. The tooling fixture moves downward under the action of the guide rail. The fixed bracket remains stationary, and the movable bracket 53 begins to slide downward under force. The first clamping alignment structure 1 and the second clamping alignment structure 2 move downward accordingly with the movement of the movable bracket 53. When they move to the third horizontal segment 1032, the first clamping alignment structure 1 corresponds to the battery cell 7. Around the perimeter, the second clamping alignment structure 2 corresponds to the perimeter of the outer casing 8. Simultaneously, the pressing structure 6 (telescopic drive device) pushes the outer casing 8 a short distance towards the battery cell 7. The drive assembly 3 drives the first clamping alignment structure 1 and the second clamping alignment structure 2 to synchronously perform clamping alignment, thereby adjusting the vertical alignment of the battery cell 7 and the outer casing 8 and fixing them. Afterwards, the tooling fixture continues to slide on the guide rail 101 until the second horizontal section 104. At this point, the first clamping alignment structure 1 stops moving downwards, while the second clamping alignment structure 2 continues to move downwards, fitting a portion of the outer casing 8 into the battery cell 7. When the second clamping... When the alignment structure 2 and the first clamping alignment structure 1 slide to their limit positions, the second clamping alignment structure stops descending. Finally, the pressing structure 6 (telescopic drive device) pushes the outer casing 8 towards the battery cell 7 until the battery cell 7 is completely inserted into the outer casing 8. The battery cell and outer casing undergo position correction, battery cell pre-insertion, and battery cell push-insertion sequentially, avoiding damage to the battery cell or outer casing due to misalignment during initial insertion. This greatly improves the yield rate. Furthermore, since the above steps are always performed during battery cell feeding in this application, although the battery cell insertion is disassembled and involves more steps, the overall efficiency is significantly improved. However, these additional steps will not interrupt the original cell delivery process, so they will not interfere with or hinder the cell assembly process. This solution can complete the cell assembly process quickly and efficiently. When the tooling fixture slides to the second transition section 105, the cell 7 and the outer casing 8 are assembled. The movable bracket 53 slides upward, and the transmission plate 98 abuts against the sliding member 97, causing the second linkage rod 96 to slide upward synchronously. The second linkage rod 96 then drives the first clamping body 11 to slide upward. At the same time, the elastic reset member 93 elastically resets, opening the first clamping body 11 and the second clamping body 21, and the tooling fixture is reset as a whole.

[0075] See appendix Figures 10 to 12As shown, in the second embodiment, the first conveyor line 20 and the second conveyor line 10 can also be at the same horizontal position. In this embodiment, it is necessary to make corresponding adjustments to the above-mentioned shell insertion execution structure. For example, the tooling fixture 100 adopts the same structural design as the previous embodiment, only changing the setting direction of the clamping alignment structure, the guide structure 5, and the pressing structure 6. In the previous embodiment, the clamping center axis of the clamping alignment structure is set vertically, while in this embodiment, the clamping center axis of the clamping alignment structure is set horizontally. In the previous embodiment, the guiding direction of the guide structure 5 is vertical, that is, the sliding direction of the movable bracket 53 and the second clamping alignment structure 2 is vertical. In this embodiment, the sliding direction of the movable bracket 53 and the second clamping alignment structure 2 is set horizontally. In the previous embodiment, the pushing direction of the pressing structure 6 is set vertically, while in this embodiment, the pushing direction of the pressing structure 6 is set horizontally. Regarding the housing 8 fixing assembly, it only serves to pick up the housing 8. Therefore, the housing 8 fixing assembly can be adapted to pick up the housing 8 from the side, or it can maintain its original structure to pick up the housing 8 directly from the top (in this structure, the housing 8 fixing assembly needs to be designed separately from the press-fitting structure 6). Correspondingly, the power input assembly in this embodiment is also modified accordingly. In this embodiment, the guide rail 101 is also set as a multi-segment. In the previous embodiment, the first horizontal segment 102 and the second horizontal segment 104 have a height difference. In this embodiment, the first horizontal segment 102 and the second horizontal segment 104 are at the same horizontal position, but the second horizontal segment 104 is closer to the first conveyor line, and the first horizontal segment 102 is farther from the first conveyor line. This can be regarded as the first horizontal segment 102 and the second horizontal segment 104 in the previous embodiment being rotated 90°.

[0076] In this embodiment, the tooling fixture 100 is mounted on the second conveyor line 10. The second conveyor line 10 synchronously drives the tooling fixture 100. First, the suction cup assembly 61 grips the outer shell 8 to the alignment port. Then, the second conveyor line 10 continues to drive the outer shell 8 to the side of the battery cell 7 in the horizontal direction. Under the action of the guide rail 101, the tooling fixture 100 moves towards the battery cell. The fixed bracket remains stationary, and the movable bracket 53 begins to slide towards the battery cell under force. The first clamping alignment structure 1 and the second clamping alignment structure 2 move accordingly with the movement of the movable bracket 53, and the battery cell moves accordingly. When it moves to the third horizontal segment 1032, the first clamping... Alignment structure 1 corresponds to the periphery of the battery cell 7, and second clamping alignment structure 2 corresponds to the periphery of the outer casing 8. Simultaneously, pressing structure 6 (telescopic drive device) pushes the outer casing 8 a short distance toward the battery cell 7. Drive assembly 3 drives first clamping alignment structure 1 and second clamping alignment structure 2 to synchronously perform clamping alignment, thereby adjusting the horizontal position of the battery cell 7 and the outer casing 8 and fixing them. Afterwards, tooling fixture 100 continues to slide on guide rail 101 until the second horizontal segment 104, at which point first clamping alignment structure 1 stops advancing, while second clamping alignment structure 2 continues to slide toward the battery cell, partially clamping the outer casing 8. When the second clamping alignment structure 2 slides to its limit position with the first clamping alignment structure 1, the second clamping alignment structure stops sliding. Finally, the pressing structure 6 (telescopic drive device) pushes the outer shell 8 towards the battery cell 7 until the battery cell 7 is completely inserted into the outer shell 8. The battery cell and outer shell undergo position correction, battery cell pre-insertion into the shell, and battery cell push-in into the shell in sequence, avoiding damage to the battery cell or outer shell due to misalignment during the first insertion. This can greatly improve the yield rate. Furthermore, since the above steps are always performed during battery cell transportation in this application, although the battery cell insertion is decomposed and involves more steps, the process is more efficient. The steps are different, but these additional steps will not interrupt the original cell delivery process, so they will not interfere with or hinder the cell assembly process. This solution can complete the cell assembly process quickly and well. When the tooling fixture 100 slides to the second transition section 105, the cell 7 and the outer shell 8 are assembled. The movable bracket 53 slides away from the cell direction, and the transmission plate 98 abuts against the sliding member 97, causing the second linkage rod 96 to slide synchronously. The second linkage rod 96 then drives the first clamping body 11 to slide. At the same time, the elastic reset member 93 elastically resets, popping the first clamping body 11 and the second clamping body 21 apart, and the tooling fixture is reset as a whole.

[0077] This application further proposes a method for inserting battery cells into a casing, see appendix. Figure 13 , 14 As shown, the specific methods for inserting battery cells into the casing include:

[0078] Step S1: Convey the outer casing 8 and the battery cell 7 separately to ensure that the outer casing 8 and the battery cell 7 are aligned (the outer casing 8 and the battery cell 7 are basically coaxial). In this step, different conveying devices are needed to convey the outer casing 8 and the battery cell 7 synchronously. The outer casing 8 and the battery cell 7 are kept in a coaxial position during the conveying process. That is, the outer casing 8 and the battery cell 7 are conveyed by different conveying devices. During the conveying process, the conveying speed calculated in advance can ensure that the outer casing 8 and the battery cell 7 are theoretically kept in a coaxial alignment. Of course, some errors will occur during the conveying process. These errors will cause the outer casing 8 and the battery cell 7 to shift their positions during the conveying process. Therefore, the outer casing 8 and the battery cell 7 will be misaligned in practice. This step only needs to ensure that the outer casing 8 and the battery cell 7 are basically coaxially aligned.

[0079] Step S2: Drive the housing 8 and the battery cell 7 to be conveyed at the same speed and in the same direction. This step ensures that the housing 8 and the battery cell 7 are relatively stationary. When the housing 8 and the battery cell 7 are relatively stationary, it is convenient to perform the subsequent core-pushing into the housing step.

[0080] Step S3, Push Core into Shell: In this step, while keeping the shell 8 and the battery cell 7 relatively stationary, push the shell 8 towards the battery cell 7 so that the shell 8 fits onto the battery cell 7 and the battery cell 7 enters the shell 8. In this step, there is no need to move the battery cell 7, so that the battery cell 7 remains on the original conveying device when entering the shell. After the battery cell is entered into the shell, there is no need to transfer the battery cell 7 back to the conveying line, thus greatly improving the efficiency of battery cell entering the shell.

[0081] Further, see appendix. Figure 11 The control methods for core insertion into the shell include:

[0082] In step S31, the positions of the outer casing 8 and the battery cell 7 are corrected. First, the tooling is driven to move a short distance in the direction of the battery cell 7, and then the first clamping alignment structure 1 and the second clamping alignment structure 2 are driven to center and clamp, thereby clamping and aligning the battery cell 7 and the outer casing 8 on the same central axis, and correcting the coaxiality of the outer casing 8 and the battery cell 7.

[0083] Step S32: Pre-insertion of battery cell 7 into the casing, i.e., driving the casing 8 closer to the battery cell 7, so that a portion of the battery cell 7 is inserted into the casing 8; specifically, in step S31, the positions of the battery cell 7 and the casing 8 have been corrected and the distance between the battery cell 7 and the casing 8 has been shortened. Therefore, in step S32, it is necessary to keep the first clamping alignment structure 1 clamping the battery cell 7, while keeping the second clamping alignment structure 2 clamping the casing 8. The guide structure 5 is used to guide the first clamping alignment structure 1 and the second clamping alignment structure 2 to slide towards each other, thereby guiding the battery cell 7 and the casing 8 to move closer to each other. By driving the second clamping alignment structure 2 to clamp the casing 8 and slide towards the battery cell 7, a portion of the battery cell 7 is inserted into the casing 8, completing the pre-insertion of battery cell 7 into the casing.

[0084] Step S33, pressing the core into the casing, that is, pushing the outer casing 8 to continue moving towards the battery cell 7 until the outer casing 8 is completely fitted onto the battery cell 7; specifically, the pre-installation of the battery cell 7 has been completed in step S32, and a part of the battery cell 7 has entered the outer casing 8. The outer casing 8 can guide the installation of the battery cell 7. Therefore, in step S33, the pressing structure 66 is used to directly push the outer casing 8 to completely press the outer casing 8 onto the battery cell 7, and finally the battery cell is completely installed into the casing.

[0085] By breaking down the traditional cell insertion process into three steps—S31, S32, and S33—the cell 7 and the casing 8 undergo position correction, cell 7 pre-insertion, and cell push-insertion sequentially. This avoids the situation where the cell 7 or casing 8 is damaged due to misalignment during initial insertion, thus greatly improving the yield rate. Furthermore, since the above steps are always performed during the cell 7 transport in this application, although the cell insertion process is broken down into three steps, these additional steps do not interrupt the original cell 7 transport process and therefore do not interfere with or hinder the cell insertion assembly process. This solution can complete the cell insertion process quickly and efficiently.

[0086] In step S4, after the outer casing 8 is fitted onto the battery cell 7, the outer casing 8 is controlled to detach from the first carrier. The second conveyor line 10 can perform cyclic conveying. Through cyclic conveying, the second carrier can repeatedly perform the steps of picking up the outer casing 8, inserting the battery cell into the casing, and unloading the outer casing 8. The battery cell is inserted into the casing when the first carrier and the second carrier are facing each other. The assembly of the battery cell 7 and the outer casing 8 can be completed during the conveying of the battery cell 7, which greatly improves the efficiency of inserting the battery cell into the casing.

[0087] Preferably, in this application, the first and second carriers are driven by magnetic drive. In this way, when transporting the outer shell 8 and the battery cell 7, the frictional resistance is very small, and the outer shell 8 and the battery cell 7 will not generate violent vibrations during the transport process. This allows the relative static state of the outer shell 8 and the battery cell 7 to be well maintained. When performing the battery cell insertion step, the outer shell 8 can be accurately pressed onto the battery cell 7 without the vibration generated during the transport process having an adverse effect on the battery cell insertion. This ensures the battery cell insertion effect and improves the yield.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
