Description

Technical Field

[0001] This utility model relates to the field of battery cell manufacturing technology, and more specifically, to a battery cell assembly mechanism. Background Technology

[0002] During the production of solar cells, the cells are typically placed in specially designed baskets and circulated between different production stages. In practice, the baskets are inevitably subjected to shaking during transportation, causing the cells inside to become misaligned, and some cells may even protrude outside the basket.

[0003] This unevenness can cause a series of problems. For example, when automated equipment removes solar cells, the misalignment of the cells can easily trigger a blockage alarm; another example is that AOI (Automated Optical Inspection) systems may fail to accurately identify complete solar cells, leading to defective products flowing into subsequent processes. These anomalies not only affect production efficiency but can also increase the defect rate and reduce product quality.

[0004] In related technologies, current solutions mainly rely on careful handling of the solar cells during manual loading to prevent them from protruding. However, the inventors have found that the above solutions have obvious drawbacks: manual operation is inefficient, labor-intensive, and costly, and it is still difficult to completely avoid the problem of uneven solar cells.

[0020] In related technologies, manual loading is used, requiring operators to be extremely careful to prevent the solar cells from protruding. However, this method still suffers from low efficiency, high labor intensity, and high cost, and it is difficult to completely guarantee the neatness of the solar cells.

[0021] To address the aforementioned problems, this utility model provides a battery cell assembling mechanism, applied in the field of battery cell production technology, for automatically arranging battery cells in a basket to ensure neat alignment. This solves various abnormalities caused by uneven battery cells, reduces manual intervention, improves production efficiency, and lowers labor costs.

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] The following describes in detail the overall structure, working principle, and technical effects of the battery cell assembly mechanism provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0029] Please see Figures 1 to 3 This utility model provides a battery cell 30, relating to the field of battery cell 30 production technology. It can automatically arrange the battery cells 30 in the basket 50, making them neatly arranged. This solves various abnormal problems caused by uneven battery cells 30, reduces manual intervention, improves production efficiency, and lowers labor costs. Figure 1 As shown, the battery cell 30 includes a vacuum generator 100, a cylinder 300, and a holding assembly 500.

[0030] The cylinder 300 includes a cylinder body 310 and a piston rod 330, with the inner cavity of the cylinder body 310 communicating with the vacuum generator 100, and the piston rod 330 slidably connected to the cylinder body 310. The piston rod 330 is used to extend into or out of the cylinder body 310 under the action of the vacuum generator 100. It is understood that the movement of the piston rod 330 is determined by the airflow generated by the vacuum generator 100. Based on the above, a supporting assembly 500 is connected to the piston rod 330 and is used to support multiple battery cells 30 when the piston rod 330 extends out of the cylinder body 310, thereby arranging the multiple battery cells 30 neatly.

[0031] In practical applications, before the flower basket 50 carrying the battery cell 30 enters the automated equipment, such as... Figure 2 As shown, the battery cells 30 are not neatly arranged due to vibration during transportation. At this time, the battery cell aligning mechanism 10 provided by this utility model begins to align the cells. That is, the vacuum generator 100 starts working, generating positive pressure, and pushing the piston rod 330 to extend. As the piston rod 330 extends, the holding assembly 500 contacts the battery cells 30 and pushes the battery cells 30 to align them neatly, specifically as follows: Figure 3 As shown. After the entire assembly is completed, the vacuum generator 100 switches to negative pressure, pulling the piston rod 330 back and holding the assembly 500 away from the battery cell 30. At this time, the battery cells 30 in the basket 50 are neatly arranged and can smoothly enter the subsequent process.

[0032] Based on the above settings, that is, to explain, this utility model provides a battery cell assembly mechanism 10, which realizes automatic adjustment of the battery cells 30 in the basket 50. On the one hand, it makes the battery cells 30 in the basket 50 neatly arranged, avoiding problems during subsequent automated cell picking and testing; on the other hand, it reduces manual intervention, improves production efficiency, and reduces labor costs.

[0033] Please refer to it again. Figure 1 The cell assembly mechanism 10 also includes a mounting base 700, on which both the vacuum generator 100 and the cylinder 300 are mounted. It is understood that centrally mounting the vacuum generator 100 and the cylinder 300 on the mounting base 700 facilitates overall handling and transfer, improving efficiency. To further enhance the stability and reliability of the entire mechanism, the cell assembly mechanism 10 also includes a third fastener. The cylinder body 310 is connected to the mounting base 700 via the third fastener to ensure that the cylinder 300 does not shift during operation.

[0034] Furthermore, to improve the overall efficiency of the battery cell assembling mechanism 10 provided by this utility model, the number of cylinders 300 is at least two, and each cylinder 300 is connected to the vacuum generator 100 to facilitate the arrangement of battery cells 30 in multiple baskets 50. Correspondingly, the supporting components 500 correspond one-to-one with the cylinders 300, ensuring that the action of each cylinder 300 can accurately act on the battery cell 30 in the corresponding basket 50. It should be noted that the one-to-one correspondence here refers to a one-to-one correspondence in position and quantity, that is, each cylinder 300 corresponds to one supporting component 500.

[0035] During operation, when the piston rod 330 needs to be extended, the vacuum generator 100 generates positive pressure, pushing airflow into the inner cavity of the cylinder 300; conversely, when the piston rod 330 needs to be retracted, the vacuum generator 100 switches to negative pressure, drawing airflow out of the inner cavity of the cylinder 300. In this way, the vacuum generator 100 can efficiently control the coordinated action of multiple cylinders 300, ensuring a fast and precise process. Specifically, the number of cylinders 300 can be flexibly set according to the actual application scenario; it can be one, two, three, or even more.

[0036] In an optional embodiment, the cell assembly mechanism 10 further includes an air pipe 200, through which the vacuum generator 100 is connected to the inner cavity of the cylinder 310. It is understood that, on the one hand, the air pipe 200 can efficiently transmit the airflow generated by the vacuum generator 100 to the inner cavity of the cylinder 300, preventing leakage or attenuation of the airflow during transmission, thereby ensuring the stability of the cylinder 300's operation; on the other hand, the air pipe 200 has a certain degree of flexibility and plasticity, allowing it to be bent or its direction adjusted according to the actual equipment layout.

[0037] In particular, in multi-cylinder 300 applications, the air pipe 200 can connect each cylinder 300 to the vacuum generator 100, ensuring that the vacuum generator 100 can control the operation of multiple cylinders 300 simultaneously or independently. For example, when it is necessary to process the battery cells 30 in multiple flower baskets 50 as a whole, the air pipe 200 can distribute the airflow of the vacuum generator 100 to each cylinder 300, achieving synchronous or step-by-step operation.

[0038] Please refer to it again. Figures 1 to 3 In the embodiments provided by this utility model, the supporting assembly 500 includes a connecting plate 510 and a baffle 530. One side of the connecting plate 510 is connected to the piston rod 330, and the other side is connected to the baffle 530. That is, the connecting plate 510 connects the piston rod 330 and the baffle 530 together, ensuring a stable connection between the two and transmitting the movement of the piston rod 330. The baffle 530 is used to support multiple battery cells 30, ensuring the consistency of the multiple battery cells 30 when arranged, and improving the overall quality of the product.

[0039] In some embodiments, there is one baffle 530, whose projection on a preset plane (i.e., a plane perpendicular to the extension and retraction direction of the piston rod 330) completely covers all the battery cells 30, ensuring that all the battery cells 30 can be held by the baffle 530, achieving a neat overall arrangement. In other embodiments, there are at least two baffles 530, which are spaced apart to hold the battery cells 30 from different positions, ensuring the consistency and neatness of the battery cell arrangement. Furthermore, it is understood that, depending on the spacing, at least two baffles 530 can also arrange at least one battery cell 30 under the action of the same cylinder 300.

[0040] Furthermore, the cell assembly mechanism 10 also includes a first fastener and a second fastener. The connecting plate 510 is connected to the piston rod 330 via the first fastener, ensuring that the connecting plate 510 can move smoothly with the piston rod 330 during the operation of the cylinder 300, without loosening or falling off. The baffle 530 is connected to the connecting plate 510 via the second fastener, ensuring that it accurately holds the cell 30 during the assembly process, preventing cell failure due to unstable connection.

[0041] In the foregoing embodiments, the specific selection of the first, second, and third fasteners depends on factors such as the connection strength requirements, environmental conditions, and whether frequent disassembly is required in the actual application. For example, the first fastener can be a combination of bolts and nuts to achieve a secure connection between the connecting plate 510 and the piston rod 330. To further improve the stability of the connection, a washer can be added to the first fastener to distribute pressure and prevent loosening or damage due to excessive local stress. Similarly, the second and third fasteners can also be a combination of bolts, nuts, and washers, and their specific principles are similar to those of the first fastener, which will not be elaborated here.

[0042] Furthermore, to prevent scratches, cracks, or other mechanical damage to the surface of the battery cells 30 caused by direct hard contact, the baffle 530 has a buffer layer 531 on one side that supports multiple battery cells 30 to ensure product quality and yield. Optionally, the buffer layer 531 is made of rubber or silicone. It is understood that rubber or silicone has a certain degree of flexibility and elasticity, effectively absorbing impact and reducing the risk of damage from rigid contact.

[0043] In summary, the utility model provides a battery cell 30, including a vacuum generator 100, a cylinder 300, and a holding assembly 500. The cylinder 300 includes a cylinder body 310 and a piston rod 330, with the inner cavity of the cylinder body 310 communicating with the vacuum generator 100, and the piston rod 330 slidably connected to the cylinder body 310. Furthermore, the piston rod 330 is used to extend into or out of the cylinder body 310 under the action of the vacuum generator 100. It is understood that the movement of the piston rod 330 is determined by the airflow generated by the vacuum generator 100. Based on the above, the holding assembly 500 is connected to the piston rod 330 and is used to hold multiple battery cells 30 together when the piston rod 330 extends out of the cylinder body 310, thereby arranging the multiple battery cells 30 neatly. Based on the above settings, that is, to explain, this utility model provides a battery cell assembly mechanism 10, which realizes automatic adjustment of the battery cells 30 in the basket 50. On the one hand, it makes the battery cells 30 in the basket 50 neatly arranged, avoiding problems during subsequent automated cell picking and testing; on the other hand, it reduces manual intervention, improves production efficiency, and reduces labor costs.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
