[0002] In the processing of lithium battery electrodes, cartridges are typically used for transporting the electrodes, replacing traditional manual handling by moving the processed or unprocessed materials. After die-cutting, the incoming electrode rolls are punched into electrodes of specified dimensions and neatly stacked in cartridges. The cartridges then transport the electrodes to the baking and stacking stages. However, during this transport, the radius (R) corners of the electrodes may randomly collide with the guide posts of the cartridges, causing damage and bending. Damaged R-corners can lead to the following problems: the stacking CCD may fail to accurately capture abnormal electrode corner information, resulting in electrode loss and misalignment; when electrodes with damaged R-corners are stacked into the battery cell, hidden foreign objects and burrs can cause poor cell appearance and a fire risk.

[0022] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0023] A magazine designed to prevent damage to the radius (R) angle of the battery cell electrode, as shown in the reference. Figure 1 and Figure 2 The device includes a base plate 10 and a bracket 20 fixed to the base plate 10. The bracket 20 includes guide posts 21 arranged circumferentially on the four sides of the base plate 10. In this invention, the base plate 10 is rectangular, and the four guide posts 21 are all perpendicular to the base plate 10, and are respectively arranged on the four sides of the base plate 10. The four guide posts 21 and the base plate 10 form a hollow receiving space 30, which is used to accommodate the electrode 40. The electrode 40 slides into the receiving space 30 from above the four guide posts 21 for storage. It should be noted that the four guide posts 21 are staggered from the four corners of the electrode 40, and the positions of the four guide posts 21 are set to avoid the four right angles of the electrode 40, so as to prevent the four guide posts 21 from contacting and damaging the four R-corners of the electrode 40 after the electrode 40 is placed in the receiving space 30. The size of the receiving space 30 defined by the four guide posts 21 is adapted to the size of the electrode 40 so that the electrode 40 can be contained between the four guide posts 21 after being placed in the receiving space 30, thus preventing the electrode 40 from shifting.

[0024] Furthermore, referring to Figure 1 The distance between the inner wall of the guide post 21 and the outer wall of the electrode 40 is 1mm-2mm. This ensures that the guide post 21 limits the electrode 40 while preventing direct contact between the guide post 21 and the electrode 40, thus avoiding damage to the electrode 40. It should be noted that a buffer portion can be provided on the inner wall of the guide post 21 to reduce damage caused by direct contact between the guide post 21 and the electrode 40. The buffer portion is made of insulating non-metallic material.

[0025] Furthermore, referring to Figure 1 and Figure 2 Each guide post 21 has a smooth chamfer 211 on the inner side of its top. The inner R angle of the top of the guide post 21 is set with a 45° angled smooth chamfer 211. The chamfer 211 is set to reduce damage to the edge of the electrode 40 when the electrode 40 falls between the four guide posts 21.

[0026] Reference Figure 1The base plate 10 is provided with a support plate 50, which is used to support the electrode 40. The support plate 50 is located between four guide posts 21. After the electrode 40 is stored in the receiving space 30, it is stacked on top of the support plate 50.

[0027] Furthermore, referring to Figure 1 and Figure 2 Each guide post 21 has a connecting plate 60 on its outer side. The connecting plate 60 is arranged horizontally and is fixed to the guide post 21 by bolts or screws. The connecting plates 60 on the outer side of each guide post 21 are connected sequentially to form a rectangular hollow shape. Both ends of each connecting plate 60 are connected and fixed to the adjacent connecting plates 60. It should be noted that adjacent connecting plates 60 are fixed with screws. The connecting plates 60 enhance the stability of the magazine structure.

[0028] Furthermore, referring to Figure 1 and Figure 2 The two connecting plates 60 arranged opposite each other are provided with retrieval slots 61. The two retrieval slots 61 are used to facilitate manual insertion of both hands to lift and move the magazine.

[0029] Furthermore, referring to Figure 1 and Figure 2 Each guide post 21 has a sliding part 212 at its bottom. A groove 11 is formed on the base plate 10 relative to the position of each guide post 21. The groove 11 is strip-shaped and perpendicular to the side of each guide post 21. The sliding part 212 at the bottom of the guide post 21 slides within the groove 11 to adjust the position of the guide post 21. It should be noted that each guide post 21 can slide along the length of the groove 11 to adjust its position. By changing the position of the guide post 21, the size of the accommodating space 30 is changed, thereby accommodating electrode sheets 40 of different sizes.

[0030] Furthermore, referring to Figure 1 and Figure 2 The sliding part 212 is fixed to the slide groove 11 by screws. The sliding part 212 is fixed to the position on the slide groove 11 by screws, so as to fix the position of the guide post 21.

[0031] Furthermore, referring to Figure 1 and Figure 2 Each slide groove 11 has a spare slide groove 12 on one side. The spare slide groove 12 and slide groove 11 are set at a certain distance apart. The spare slide groove 12 and slide groove 11 are located at 1 / 3 and 2 / 3 of the side of the base plate 10, respectively. Each guide post 21 can slide into the slide groove 11 or the spare slide groove 12 according to actual needs to adapt to the storage needs when the electrode tabs of the electrode plate 40 are distributed at different positions.

[0032] Furthermore, referring to Figure 1 and Figure 2 Each connecting plate 60 has a screw fixing groove 62 near one side, which allows screws to pass through and slide to adjust the fixing position. The screw fixing groove 62 is provided along the length of the connecting plate 60. A screw fixing groove 62 is provided at the connection position of two adjacent connecting plates 60, allowing screws to pass through and insert into the side of another connecting plate 60 to fix the connection position of the two adjacent connecting plates 60. When each guide post 21 slides along the slide groove 11 to adjust its position, the connection position between each connecting plate 60 will change. By providing the screw fixing groove 62, it is convenient for the screw to slide and fix the position between two adjacent connecting plates 60 when changing the connection position. It should be noted that two or three screw fixing grooves 62 can be provided according to actual fixing needs to increase the connectivity between adjacent connecting plates 60.

[0033] This invention effectively prevents the R-angles of the electrode 40 from randomly colliding with the guide posts 21 of the magazine during the transfer of the electrode 40, thus avoiding damage or bending of the R-angles of the electrode 40. Furthermore, the guide posts 21 are slidably connected to the base plate 10, allowing the size of the accommodating space 30 to be adjusted according to the size of the electrode 40. This simplifies the mechanical structure while maximizing the adaptability to different models of electrode 40.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
