[0022] The following describes in detail, with reference to the accompanying drawings, the battery cell baking rack 10 according to an embodiment of the present invention.

[0023] Reference Figures 1-3 As shown, the battery cell baking rack 10 includes a fixed tray 1 with multiple battery cell fixing slots 11. Each battery cell fixing slot 11 has two spaced-apart partitions 12 to divide it into a battery cell slot segment 111 and two tab slot segments 112. The battery cell slot segment 111 is located between the two partitions 12. Each partition 12 forms a tab slot segment 112 on the side opposite to the battery cell slot segment 111. The partition 12 has a through slot 121 that connects the tab slot segments 112 and the battery cell slot segment 111 on both sides.

[0024] Specifically, the cell baking rack 10 can fix and hold the cells during cell baking. The cell baking rack 10 includes a fixed tray 1 with multiple cell fixing slots 11. Each cell fixing slot 11 can fix a corresponding cell. The cell can be a cylindrical cell. The cell includes a cell body and two tabs. The two tabs are respectively connected to the two ends of the cell body. The two tabs are a positive tab and a negative tab.

[0025] The cell fixing slot 11 has two spaced-apart partition plates 12 to divide the cell fixing slot 11 into a cell slot segment 111 and two tab slot segments 112. The cell slot segment 111 is located between the two partition plates 12. Each partition plate 12 forms a tab slot segment 112 on the side away from the cell slot segment 111. That is, the cell slot segment 111 is located between the two tab slot segments 112. The cell slot segment 111 and the tab slot segment 112 are separated by the partition plates 12. At the same time, the partition plates 12 have through slots 121 that connect the tab slot segments 112 and the cell slot segment 111 on both sides.

[0026] When the battery cell is placed into the battery cell fixing slot 11 of the fixing tray 1, the battery cell body can be placed into the battery cell slot section 111. The tab on one side of the battery cell body can extend into the tab slot section 112 through the through slot 121 of a partition plate 12, and the tab on the other side of the battery cell body can extend into another tab slot section 112 through the through slot 121 of another partition plate 12. Thus, the battery cell slot section 111 can fix and accommodate the battery cell body, and the tab slot section 112 and the through slot 121 can fix and accommodate the corresponding tabs.

[0027] During the cell baking process, each cell fixing slot 11 on the fixing tray 1 can hold and fix a corresponding cell. Since each tab of the cell is accommodated and fixed by the corresponding tab slot 112 and through slot 121, the tabs of multiple cells fixed on the fixing tray 1 will not collide or contact, thereby avoiding short circuits of the cells.

[0028] According to the embodiment of the present invention, the battery cell baking rack 10 has a plurality of battery cell fixing slots 11 on the fixed tray 1. Each battery cell fixing slot 11 has a connected battery cell slot section 111 and two tab slot sections 112. The battery cell slot section 111 can fix the battery cell body, and the tab slot section 112 and the through slot 121 can fix the corresponding tabs, thereby avoiding contact between the tabs of multiple batteries, reducing the risk of battery cell short circuit, and thus improving the safety of the battery cell baking rack 10.

[0029] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the width of the tab groove section 112 is less than or equal to the width of the cell groove section 111.

[0030] Specifically, the width direction of the groove is Figure 1 and Figure 2 In the left-right direction, the size of the tab is smaller than the size of the cell body, and the width of the tab slot 112 can be less than or equal to the width of the cell slot 111.

[0031] When the width of the tab groove 112 is equal to the width of the cell groove 111, the irregular area of ​​the cell fixing groove 11 can be reduced, so as to facilitate the manufacturing of the cell fixing groove 11.

[0032] When the width of the tab groove section 112 is smaller than the width of the cell groove section 111, the space occupied by the tab groove section 112 can be reduced, which is conducive to improving space utilization and allowing the fixed tray 1 to open more cell fixing grooves 11.

[0033] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, multiple cell fixing slots are arranged in multiple rows.

[0034] Specifically, multiple battery cells can be arranged in rows on the left and right sides, and multiple rows of battery cell fixing slots 11 can be formed in the front and back directions. The multiple rows of battery cell fixing slots 11 make it easy to pick up and put multiple battery cells on the fixing tray 1, thus improving the ease of use of the battery cell baking rack 10.

[0035] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, in two adjacent rows of battery cell fixing slots 11, the tab slot section 112 on one side of one row of battery cell fixing slots 11 is arranged alternately with the tab slot section 112 on the other side of the other row of battery cell fixing slots 11.

[0036] Specifically, in two adjacent rows of cell fixing slots 11, the tab slot sections 112 on opposite sides can be arranged alternately in the left and right directions to form an interlocking arrangement of the two rows of cell fixing slots 11 at the tab slot sections 112. When the width of the tab slot section 112 is smaller than the width of the cell slot section 111, the space utilization of the cell baking rack 10 can be improved, allowing the cell baking rack 10 to have a larger number of cell fixing slots 11.

[0037] Reference Figure 2 As shown, the width of the tab groove section 112 can be half the width of the cell groove section 111 to avoid the tab groove section 112 occupying too much space in the left and right directions, so that the tab groove sections 112 are arranged more closely in alternating positions, and the cell fixing grooves 11 in the same row can also be arranged closely, reducing the spacing between the cell fixing grooves 11 in the same row, thereby making full use of the space inside the cell baking rack 10, so that more cell fixing grooves 11 can be opened.

[0038] In some embodiments of this utility model, reference is made to Figure 1 As shown, the through groove 121 extends to the top edge of the partition plate 12 and communicates with the slot of the cell fixing groove 11.

[0039] Specifically, the through groove 121 can be a notch, that is, the through groove 121 is not only in the thickness direction of the partition plate 12 ( Figure 1 The through-slot 121 extends towards the opening of the cell fixing slot 11 in the front-back direction of the partition plate 12, and forms a notch at the top of the partition plate 12 towards the opening of the cell fixing slot 11. Thus, when the cell is placed into the cell fixing slot 11 from top to bottom, the cell body falls directly into the cell slot section 111, and part of the tab can be directly inserted into the through-slot 121 on the partition plate 12 through the notch at the top of the through-slot 121. This allows the tab to pass through the through-slot 121 and extend into the tab slot section 112, thereby improving the efficiency of placing the cell into the cell fixing slot 11.

[0040] In some embodiments of this utility model, reference is made to Figure 1 As shown, the width of the through groove 121 gradually increases from the bottom of the cell fixing groove 11 to the groove opening.

[0041] Specifically, the through groove 121 can be a trapezoidal groove that is wider at the top and narrower at the bottom. The upper end of the through groove 121 is wider to facilitate the insertion of the electrode tab, while the lower end of the through groove 121 is narrower to limit the insertion of the electrode tab. The inclined groove walls on both sides of the through groove 121 can guide the electrode tab when it is inserted, thereby reducing the difficulty of inserting the electrode tab and improving the efficiency of inserting the battery cell into the battery cell fixing groove 11.

[0042] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, the bottom wall of the cell fixing groove 11 is provided with at least one heat exchange through hole 113.

[0043] Specifically, the heat exchange through-hole 113 can be a circular or polygonal hole, and it can penetrate the bottom wall of the cell fixing groove 11. During baking, hot air can enter the cell fixing groove 11 through the slot at the top and the heat exchange through-hole 113 at the bottom, thereby improving the heating efficiency of the cell baking and ensuring uniform heating of the cell. In addition, the heat exchange through-hole 113 can reduce the weight of the fixing tray 1 and lower its cost.

[0044] It should be noted that one or more heat exchange through holes 113 may be provided in the bottom wall of a cell fixing groove 11. When a heat exchange through hole 113 is provided in the bottom wall of the cell fixing groove 11, the heat exchange through hole 113 may be located within the cell groove section 111 to ensure the baking efficiency and uniform heating of the cell body. When multiple heat exchange through holes 113 are provided in the bottom wall of the cell fixing groove 11, all of the multiple heat exchange through holes 113 may be located within the cell groove section 111, or the multiple heat exchange through holes 113 may be distributed between the cell groove section 111 and the tab groove section 112. Multiple heat exchange through holes 113 can further improve the heating efficiency and uniform heating of the cell during baking.

[0045] In some embodiments of this utility model, reference is made to Figure 1 As shown, the battery cell baking rack 10 also includes a handle 3, which is connected to the fixed tray 1. The handle 3 can be attached to the outer wall of the fixed tray 1. When the battery cell baking rack 10 is in use, the handle 3 can facilitate the handling and retrieval of the fixed tray 1.

[0046] In some embodiments of this utility model, reference is made to Figures 1-4 As shown, the battery cell baking rack 10 also includes: multiple support legs 4, each support leg 4 is connected to the fixed tray 1, one end of the support leg 4 is higher than the fixed tray 1, and the other end of the support leg 4 forms a support leg slot 41. The arrangement of multiple support legs 4 can facilitate the stacking and use of multiple battery cell baking racks 10.

[0047] Reference Figure 4 As shown, the two cell baking racks 10 can be stacked. The upper end of the support leg 4 of the lower cell baking rack 10 is higher than its fixed tray 1 and can support the upper cell baking rack 10, so that there is space for airflow above the lower fixed tray 1, so that the cells in the lower fixed tray 1 can be heated evenly and quickly. The upper end of the lower support leg 4 can be inserted into the support leg slot 41 at the lower end of the upper support leg 4 to improve the stability of the connection between the upper and lower cell baking racks 10 and to achieve positioning and stacking.

[0048] In some embodiments, the battery cell baking rack 10 has four support legs 4, which are located at the four corners of the rectangular fixed tray 1. In other embodiments, the number of support legs 4 may be two, three, five, etc.

[0049] In some embodiments of this utility model, the fixed tray 1, handle 3 and multiple support legs 4 are integrally connected. The fixed tray 1, handle 3 and multiple support legs 4 can be integrally formed by injection molding or 3D printing, so as to facilitate the manufacturing of the battery cell baking rack 10 and reduce the manufacturing and assembly cost of the battery cell baking rack 10.
