Description

Technical Field

[0001] This utility model relates to the technical field of magazine adjustment devices, and in particular to a magazine adjustment device. Background Technology

[0002] With the booming development of the lithium-ion battery industry, its advantages as a new type of green high-energy battery are becoming increasingly prominent, including high capacity, no memory effect, environmental friendliness, small size, low internal resistance, low self-discharge, and long cycle life. These characteristics have led to the widespread application of lithium-ion batteries in various fields such as mobile phones, e-cigarettes, personal computers, cameras, drones, and robots. However, in the lithium-ion battery manufacturing process, especially in the storage and transportation stages after cell encapsulation and electrolyte filling, a key technical challenge remains: how to efficiently and accurately adjust the magazine's limiting dimensions to accommodate different cell models.

[0003] Traditional magazine designs are often customized for specific battery models. This means that whenever a new battery model enters production, a new magazine adjustment fixture needs to be developed. This not only increases production costs but also reduces the flexibility of the production line. More importantly, during the adjustment of the magazine's limiting dimensions, the fixture is often subjected to significant friction because it needs to simulate the actual size of the battery to ensure a tight fit with the adjustment fixture and achieve good consistency. This process makes it difficult to remove the fixture smoothly from the magazine after adjustment, severely impacting production efficiency and potentially damaging the adjustment fixture.

[0004] Furthermore, with the diversification of battery models, higher demands are placed on the precision and efficiency of adjusting the magazine's limiting dimensions. Traditional adjustment methods often rely on manual experience and simple mechanical structures, making it difficult to achieve precise and rapid adjustments. Moreover, errors are easily introduced during the adjustment process, affecting the stability and safety of the battery cells within the magazine.

[0005] Therefore, we propose a magazine adjustment device. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides a magazine adjustment device that achieves rapid and precise adjustment of the magazine limit through a linkage mechanism, which has good adaptability and flexibility, while also taking into account ease of operation and safety.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A magazine adjustment device, comprising:

[0009] The magazine base plate adjustment assembly connects to the magazine to achieve vertical positioning;

[0010] A fixing block is connected to the magazine base plate adjustment assembly, and a vertically set guide rod is connected to its middle.

[0011] The movable block is mounted on the guide rod and can move along the axial direction of the guide rod;

[0012] The linkage mechanism includes a long link and a short link. One end of the long link is hinged to a fixed block, and the other end is connected to a limiting top block assembly. One end of the short link is connected to a moving block, and the other end is hinged to the middle of the long link. It is used to transmit the movement of the moving block to the limiting top block assembly, so as to achieve precise control of the position of the limiting top block and adapt to battery cells of different sizes.

[0013] As a further improvement to the above technical solution:

[0014] The magazine base plate adjustment assembly includes a lower magazine base plate adjustment block and an upper magazine base plate adjustment block. Both blocks have positioning holes in the middle and are connected by a magazine adjustment tool guide post to form the main body of the adjustment tool, which is used to cooperate with the positioning pin on the magazine to achieve vertical positioning.

[0015] The limiting top block assembly includes a limiting top block and a limiting top block hinge seat, and the limiting top block is connected to the long connecting rod through the limiting top block hinge seat.

[0016] In the linkage mechanism, there are four long links, divided into two groups, corresponding to the long and short sides of the battery cell respectively. When the battery cell is square, the dimensions and rotation angles of the four long links are the same; when the battery cell is rectangular, the lengths and rotation angles of the two groups of long links are different to ensure that the limiting top block is always on the same plane.

[0017] In the aforementioned limiting top block assembly, the limiting top block hinge seat is bolted to the center of the limiting top block. By adjusting the tightness of the bolts, the limiting top block can be finely adjusted to accommodate the subtle differences between different magazine models.

[0018] The position of the movable block on the guide rod is not strictly limited by mechanical structure, leaving a certain amount of rotation space to accommodate the small errors of the linkage mechanism.

[0019] The guide rod has a slot, the moving block is slidably connected in the slot, and a locking bolt is connected to the moving block to restrict its axial movement, so as to precisely control the moving distance of the moving block.

[0020] The guide rod is also equipped with scale lines. In conjunction with the locking bolts on the moving block, it can be moved according to the scale lines, so that the four limit blocks can be scaled proportionally, which is suitable for battery cells of different sizes.

[0021] The guide rod end structure is connected to two half-end caps, which are bolted together and fitted onto the top of the guide rod.

[0022] It also includes a locking device that can be bolted to the end of the moving block to fix the position of the moving block when not in use.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model features a compact and reasonable structure, and is easy to operate. Through a linkage mechanism, it achieves rapid and precise adjustment of the magazine limit, exhibiting excellent adaptability and flexibility while considering both ease of operation and safety. This device not only improves production efficiency and reduces production costs but also enhances the flexibility of the production line, providing strong technical support for the lithium-ion battery manufacturing process. Its ingenious structural design, simple operation, and significant effects make it widely applicable and worthy of promotion.

[0025] In addition, this utility model also has the following advantages:

[0026] This debugging device achieves rapid and precise adjustment of the magazine limit position through a linkage mechanism. Traditional debugging methods often rely on manual experience and simple mechanical structures, making it difficult to achieve precise and rapid adjustments, and errors are easily introduced during the adjustment process. In this embodiment, the linkage mechanism, through the movement of the moving block on the guide rod, drives the short and long connecting rods to move in tandem, thereby precisely controlling the position of the limit block and meeting the storage and transportation requirements of different battery cell models. This design not only improves adjustment accuracy but also significantly shortens debugging time and increases production efficiency.

[0027] This debugging device boasts excellent adaptability and flexibility. Traditional magazine designs are often customized for specific battery models, requiring the development of new magazine debugging fixtures whenever a new battery model enters production. However, the debugging device in this embodiment, by adjusting the parameters of the linkage mechanism, can adapt to battery cells of different sizes and shapes, eliminating the need for developing new fixtures, significantly reducing production costs and improving production line flexibility. Furthermore, the bolted connection between the limiting top block and the limiting top block hinge seat allows for fine-tuning at any time, further enhancing the device's adaptability.

[0028] This debugging device is designed with ease of operation and safety in mind. The components of the linkage mechanism move in tandem, allowing the operator to precisely adjust the magazine limit simply by moving the moving block. Simultaneously, a limiting structure on the fixed block controls the rotation range of the long connecting rod, ensuring the linkage mechanism's movement does not exceed the predetermined range and avoiding safety hazards during operation. Furthermore, the debugging device has a compact structure, making it easy to carry and store, further enhancing its usability. Attached Figure Description

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] like Figures 1-2 As shown, this embodiment discloses a magazine adjustment device, including a lower magazine base plate adjustment block 1, an upper magazine base plate adjustment block 3, a magazine adjustment tooling guide post 2, a long connecting rod 6, a short connecting rod 8, a fixing block 5, a moving block 9, a limiting top block 7, a limiting top block hinge seat 14, a locking device 11, and an end cap 12. A positioning hole is provided between the lower magazine base plate adjustment block 1 and the upper magazine base plate adjustment block 3 to facilitate positioning of the adjustment device. The magazine adjustment tooling guide post 2 serves as a connecting device between the lower magazine base plate adjustment block 1 and the upper magazine base plate adjustment block 3. The long connecting rod 6 and the short connecting rod 8 are linked to limit the movement of the limiting top block 7. Using this magazine adjustment device, magazine limiting dimension adjustment can be performed conveniently and efficiently.

[0035] like Figure 1 The diagram illustrates the adjustment device of this utility model, whose structure includes a lower magazine base plate adjustment block 1, a magazine adjustment fixture guide post 2, a long connecting rod 6, a short connecting rod 8, a fixing block 5, a moving block 9, a limiting top block 7, a limiting top block hinge seat 14, a locking device 11, and an end cap 12. A positioning hole is provided between the lower magazine base plate adjustment block 1 and the upper magazine base plate adjustment block 3 to facilitate positioning of the adjustment device. The magazine adjustment fixture guide post 2 connects the lower magazine base plate adjustment block 1 and the upper magazine base plate adjustment block 3. The long connecting rod 6 and the short connecting rod 8 work together to limit the movement of the limiting top block 7. This utility model's magazine adjustment device facilitates efficient adjustment of the magazine's limiting dimensions.

[0036] like Figure 2As shown, the magazine structure in this embodiment includes a fixed frame 101 and four axially distributed movable frames 102 that can move horizontally are provided within the fixed frame 101. The battery cells are stacked between the multiple movable frames 102, and the positions of the movable frames 102 are adjustable to accommodate battery cells of different sizes. The multiple movable frames 102 are connected and fixed by connectors 103.

[0037] Specifically, the adjustment device is inserted from the top of the magazine, so that the positioning hole on the adjustment device engages with the positioning pin fixed on the magazine to achieve vertical positioning. At the same time, the moving block 9 moves axially on the guide rail, and drives multiple limit top blocks 7 to move horizontally through the short connecting rod 8 and the long connecting rod 6, opening the movable frame 102 of the magazine to the corresponding position. Then, the movable frame 102 is fixed by the connecting piece 103, thereby matching the corresponding battery cell.

[0038] In this embodiment, the positioning holes of the lower block 1 and the upper block 3 of the magazine base plate adjustment mechanism are centered, and the distance to the edge is related to the width of the target battery cell for the replacement. Stepped holes are opened around the base plate for installing M5 hexagon socket bolts 4 to connect the magazine adjustment tool guide post 2 to form the main body of the adjustment tool.

[0039] In this embodiment, the fixing block 5 has a positioning hole and is bolted to the guide rod 10 by an M3 hexagonal bolt 13, which restricts the movement of the guide rod 10 and improves the debugging accuracy of the telescopic device.

[0040] In this embodiment, four long connecting rods 6 are hinged to the fixed block 5. Limiters are provided on the fixed block 5 to control the rotation range of the long connecting rods 6 to a flat position. The ends of the long connecting rods 6 are hinged to limiter top block hinge seats 14. Simultaneously, according to the size of the battery cell, the four long connecting rods 6 are divided into two groups. When the battery cell has a square structure, the dimensions and rotation angles of the four long connecting rods 6 are the same. When the battery cell is rectangular, the lengths and rotation angles of the two groups of long connecting rods 6 are different, thereby ensuring that the multiple limiter top blocks 7 connected to the ends of the multiple long connecting rods 6 are always on the same plane.

[0041] In this embodiment, the limiting top block hinge seat 14 is bolted to the center of the limiting top block 7, and the limiting top block 7 can be finely adjusted by adjusting the tightness of the bolt.

[0042] In this embodiment, the limiting top block 7 must have good parallelism and straightness to ensure accurate debugging results. After being laid flat, the position of the limiting top block 7 should extend beyond the main body of the debugging fixture to prevent the telescopic device from malfunctioning.

[0043] In this embodiment, the short connecting rod 8 and the long connecting rod 6 are hinged at the middle of the long connecting rod 6, which restricts the movement trajectory and limit size of the limiting block 7. The short connecting rod 8 is mounted on the moving block 9.

[0044] In this embodiment, the movable block 9 is mounted on the guide rod 10. Its relative position is not strictly limited by a mechanical structure, allowing for some rotational space to accommodate minor errors in the linkage structure and reduce stress concentration. The movable block 9 has a longer portion for gripping, facilitating operation. Its end can be bolted to the locking device 11, reducing the structural size when not in use and making it easier to store.

[0045] In this embodiment, the locking device 11 is fixed to the guide rod 10 by bolts.

[0046] In another embodiment, in order to facilitate control of the moving distance of the moving block 9, a strip groove is provided on the guide rod 10, and the moving block 9 is slidably connected in the strip groove. At the same time, a locking bolt that restricts the axial movement of the moving block 9 is also connected to the moving block 9.

[0047] In another embodiment, a scale line is also provided on the guide rail 10, and a locking bolt is also connected to the moving block 9. The moving block moves according to the scale line, so that the four limit blocks can be scaled proportionally, which is suitable for different battery cells.

[0048] In this embodiment, the end structure of the guide rod 10 is connected to two half-end caps 12. The two half-end caps 12 are connected by bolts and are fitted over the guide rod 10, improving the safety and portability of the telescopic structure.

[0049] Specifically, the linkage mechanism of the debugging device mainly includes a long connecting rod 6, a short connecting rod 8, a limiting top block hinge seat 14, a limiting top block 7, a moving block 9, a fixed block 5, and a guide rod 10. The linkage mechanism is the core part of the debugging device, achieving precise adjustment of the magazine's limit through the coordinated movement of its components. The long connecting rod 6 and the short connecting rod 8 are hinged together, forming the main moving parts of the linkage mechanism, acting together on the limiting top block 7. By controlling the position of the limiting top block 7, the limiting dimension of the magazine is adjusted. The limiting top block hinge seat 14 serves as the support and adjustment component for the limiting top block 7, and is bolted to the center of the limiting top block 7, allowing the limiting top block 7 to be finely adjusted within a certain range to accommodate different magazine models. The moving block 9 is mounted on the guide rod 10, and its movement drives the short connecting rod 8 and the long connecting rod 6, thereby precisely controlling the limiting top block 7. The fixed block 5 serves as the fixed part of the linkage mechanism, connected to the guide rod 10 by bolts, ensuring the stability and accuracy of the linkage mechanism.

[0050] The working principle of the linkage mechanism is as follows: the moving block 9 moves up and down on the guide rod 10, driving the short connecting rod 8 and the long connecting rod 6 to move in tandem. The limiting block 7 at the end of the long connecting rod 6 gradually expands to its maximum size as the moving block 9 moves downwards, which is the adjusted magazine limiting size. When adjusting the magazine limiting, only the moving block 9 needs to be moved to precisely control the position of the limiting block 7, meeting the storage and transportation needs of different types of battery cells. The linkage mechanism is ingeniously designed, enabling rapid and precise adjustment of the magazine limiting while ensuring the stability and accuracy of the linkage mechanism. This makes the adjustment device applicable to different types of magazines, improving production efficiency and product quality.

[0051] The linkage mechanism design also considers preventing the movement from exceeding the specified range. A limiting structure is set on the fixed block 5 to control the rotation range of the long connecting rod 6, ensuring that the movement of the linkage mechanism does not exceed the predetermined range and guaranteeing the safety and stability of the debugging device.

[0052] In actual operation, operators can loosen the bolts to adjust the position and angle of the limiting block 7 according to the size and shape of the battery cell, so that it fits tightly against the inner wall of the magazine, effectively fixing and protecting the magazine. At the same time, the limiting block 7 is bolted to the limiting block hinge seat 14, which can be adjusted at any time to meet the storage and transportation needs of different battery cell models.

[0053] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
