Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and in particular relates to a support pad for stacking battery cells. Background Technology

[0002] Currently, after battery cells are produced, they need to be stacked and stored in a designated area for a period of time before subsequent processes such as packaging can be carried out. In existing technology, cardboard is typically used to support the battery cells. This involves first stacking a layer of battery cells on a plastic pallet using a robotic arm, then laying cardboard on top of that layer, stacking another layer of battery cells on the cardboard, laying another layer of cardboard on top of that layer, and repeating this process to stack multiple battery cells.

[0003] While using cardboard as a support plate to isolate and support individual battery cells is relatively inexpensive, it still has the following drawbacks: 1) Because cardboard lacks the function of positioning battery cells, the cells are not stacked neatly, increasing the probability of cell collapse; 2) Because cardboard cannot effectively dissipate heat from the battery cells, the temperature rise of the cells is too high, affecting the cooling time after acid addition and also increasing the storage time; 3) Since cardboard usually needs to be handled and laid manually, this not only increases the labor intensity of workers but also affects the production efficiency of batteries. Therefore, it is urgent to study a support plate for stacking battery cells to solve the above problems. Utility Model Content

[0004] The present invention provides a support pad for stacking individual battery cells, the purpose of which is to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a support pad for stacking battery cells, including a horizontally arranged support frame; multiple bearing plates are horizontally fixed side by side on the inner side of the support frame; adjacent bearing plates are connected by a partition strip; each bearing plate forms an accommodating space for placing battery cells with the edge of the support frame and the adjacent partition strip; multiple pairs of heat dissipation holes are opened side by side on the upper surface of the multiple bearing plates, and a ventilation notch is opened on one edge of the multiple heat dissipation holes near the partition strip; multiple ventilation holes are opened side by side along the length direction on the upper surface of each partition strip, and a first through hole connected to the ventilation notch is opened on the opposite side of the multiple ventilation holes.

[0007] As a preferred embodiment of this utility model, a pair of vertically distributed connecting slots are provided between any two adjacent pairs of heat dissipation holes on any one of the support plates; the two connecting slots are respectively provided on the upper and lower surfaces of the support plate; the connecting slots enable the two adjacent pairs of heat dissipation holes on the support plate to be connected together.

[0008] As a preferred embodiment of this utility model, a reinforcing plate is horizontally fixed to the inner side of each of the plurality of heat dissipation holes; and a plurality of second through holes are arranged side by side on the upper surface of each of the plurality of reinforcing plates.

[0009] As a preferred embodiment of this utility model, at least one pair of the bearing plates has multiple robotic gripping parts arranged side by side on their upper surfaces.

[0010] As a preferred embodiment of this utility model, a third through hole is provided between any two adjacent ventilation holes on any one of the ventilation holes; the third through hole enables the two adjacent ventilation holes on the ventilation hole to be connected together.

[0011] This utility model has the following beneficial effects:

[0012] This invention utilizes a robotic arm to transfer a group of battery cells and place them on a support plate, causing the battery cells to be vertically positioned in multiple accommodating spaces on the upper part of the support plate. Then, another support plate is placed horizontally on top of the same group of battery cells, with the upper part of the battery cells slidingly inserted into the accommodating space on the lower part of the other support plate. The robotic arm then transfers another group of battery cells and places them in multiple accommodating spaces on the upper part of another support plate, repeating the above steps to achieve battery cell stacking. This not only effectively improves the positioning accuracy of the battery cells but also avoids problems such as uneven stacking or misalignment that exist in existing technologies, ensuring battery production efficiency. Furthermore, after stacking, the ventilation holes allow for ventilation and heat dissipation of the battery cells, effectively improving the ventilation and heat dissipation effect and preventing problems such as excessive temperature rise in the battery pack and long cooling times after adding acid. It also reduces the storage time of the battery cells.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-6As shown, this utility model is a support pad for stacking individual battery cells, including a horizontally arranged support frame 1; multiple horizontally arranged carrier plates 2 connect opposite edges of the support frame 1, with the two carrier plates 2 furthest apart connected to the other opposite edges of the support frame 1; adjacent carrier plates 2 are connected by a separator 3; the separator 3 is parallel to the other opposite edges of the support frame 1, and its two ends are connected to opposite edges of the support frame 1; the upper surface of the carrier plate 2 is horizontally lower than the upper surface of the support frame 1, and the lower surface of the carrier plate 2 is horizontally higher than the lower surface of the support frame 1; the upper and lower surfaces of the separator 3 are respectively connected to the upper and lower surfaces of the support frame 1. The support frame 1, multiple bearing plates 2, and multiple partition bars 3 are integrally injection molded structures; each bearing plate 2 forms a pair of accommodating spaces 4 for placing battery cells with the edge of the support frame 1 and the adjacent partition bars 3, and the two accommodating spaces 4 are respectively located on the upper and lower sides of the bearing plate 2; multiple pairs of square-structured heat dissipation holes 201 are opened side by side on the upper surface of multiple bearing plates 2, and ventilation notches 202 are opened on one edge of multiple heat dissipation holes 201 near the partition bars 3; multiple rectangular-structured ventilation holes 301 are opened side by side along the length direction on the upper surface of any partition bar 3, and a first through hole 302 connected to the ventilation notch 202 is opened on the opposite side of the multiple ventilation holes 301.

[0027] In use, a robotic arm transfers a group of battery cells and places them on a support pad, causing the group of battery cells to be vertically positioned within multiple accommodating spaces 4 on the upper part of the support pad. Then, another support pad is placed horizontally on top of the same group of battery cells, with the upper part of the group of battery cells sliding into the accommodating space 4 on the lower part of the other support pad. The robotic arm then transfers another group of battery cells and places them within multiple accommodating spaces 4 on the upper part of another support pad. This process is repeated to achieve the stacking operation of the battery cells. This not only effectively improves the positioning accuracy of the battery cells but also avoids the electrical problems present in existing technologies. Issues such as unevenness or misalignment during battery cell stacking are prevented, ensuring battery production efficiency. Simultaneously, after battery cells are stacked, the ventilation holes 301 facilitate ventilation and heat dissipation for the cells, effectively improving ventilation and heat dissipation. This also prevents excessive temperature rise in the battery pack and prolonged cooling time after adding acid, and reduces the storage time of individual cells. Furthermore, since the ventilation notch 202 is connected to the first through hole 302, heat from the multiple heat dissipation holes 201 near the separator 3 is dissipated into the ventilation hole 301 through the ventilation notch 202 and the first through hole 302, accelerating heat dissipation efficiency at the bottom or top of the battery cells.

[0028] Among them, such as Figure 6As shown, a third through hole 303 is provided between two adjacent ventilation holes 301 on any one ventilation hole 301; the third through hole 303 enables the two adjacent ventilation holes 301 on any one ventilation hole 301 to be connected together. In use, by providing a third through hole 303 between two adjacent ventilation holes 301 on any one ventilation hole 301, the third through hole 303 enables the two adjacent ventilation holes 301 on any one ventilation hole 301 to be connected together, thereby further improving the ventilation and heat dissipation effect of the ventilation hole 301.

[0029] Example 2:

[0030] Based on Example 1, as follows Figure 3-5 As shown, a pair of vertically distributed connecting grooves 203 are provided between two adjacent pairs of heat dissipation holes 201 on any one of the support plates 2; the two connecting grooves 203 are respectively provided on the upper and lower surfaces of the support plate 2; the connecting grooves 203 can connect two adjacent pairs of heat dissipation holes 201 on the support plate 2; a horizontally arranged reinforcing plate 204 is integrally formed on the inner side of each of the multiple heat dissipation holes 201; the four edges of the reinforcing plate 204 are respectively connected to the four sides of the heat dissipation holes 201; the horizontal position of the upper surface of the reinforcing plate 204 is lower than the horizontal position of the upper surface of the support plate 2, and the horizontal position of the lower surface of the reinforcing plate 204 is higher than the horizontal position of the lower surface of the support plate 2; four second through holes 205 with a circular structure are arranged side by side on the upper surface of each of the multiple reinforcing plates 204. In use, a pair of vertically distributed connecting grooves 203 are provided between two adjacent pairs of heat dissipation holes 201 on the support plate 2, and the two connecting grooves 203 are respectively provided on the upper and lower surfaces of the support plate 2. The connecting grooves 203 can connect the two adjacent pairs of heat dissipation holes 201 on the support plate 2, so that the heat in the multiple pairs of heat dissipation holes 201 on the support plate 2 can be dissipated into the ventilation holes 301 through the ventilation gaps 202 and the first through holes 302, ensuring the heat dissipation efficiency of the bottom or top of the battery cell. In addition, by providing a reinforcing plate 204 on the inner side of the heat dissipation holes 201 and opening a second through hole 205 on the upper surface of the reinforcing plate 204, not only is the structural strength of the support plate 2 guaranteed, but also the heat dissipation effect of the support plate 2 on the battery cell is guaranteed.

[0031] Among them, such as Figure 2-3As shown, each of the two support plates 2 has a pair of parallel robotic gripper parts 206 on its upper surface, and two separator strips 3 are provided between the two support plates 2; the robotic gripper parts 206 are planar bodies with a square structure. In use, before stacking battery cells, multiple support pads are stacked together. When stacking battery cells, the robotic gripper uses a negative pressure suction cup on its arm to hold the robotic gripper parts 203 on the support pads, and then the robotic gripper transfers the support pads to the battery cell stacking area, thereby realizing the mechanized transfer of the support pads. This can effectively improve the transfer efficiency and placement accuracy of the support pads, while also ensuring the stacking accuracy of the battery cells.

[0032] Example 3:

[0033] Based on Example 2, as follows Figure 1-2 and Figure 7 As shown, the outer surfaces of two adjacent sides of the support frame 1 are integrally formed with multiple protrusions 101 in the shape of isosceles trapezoids along the length direction, and the top edge of the protrusions 101 in the shape of isosceles trapezoids is set on the edge of the support frame 1; the outer surfaces of two adjacent sides of the support frame 1 are integrally formed with multiple limiting grooves 102 in the shape of isosceles trapezoids along the length direction. In use, a robotic arm first transfers one support pad to the battery cell stacking area, then grasps another support pad and vertically places it from top to bottom, aligning one side of the first support pad with the two support pads parallel in length. The protrusion 101 on the second support pad slides vertically into the limiting groove 102 on the first support pad, thus assembling the two support pads. Both support pads are placed on the ground or on two sets of battery cells. This process is repeated to assemble multiple support pads, improving the connection strength between them and further ensuring the stacking effect and stability of the battery cells.
