Description

Technical Field

[0001] This utility model relates to the field of tray technology, and in particular to a fully functional adjustable soft-pack battery cell tray. Background Technology

[0002] Soft-pack batteries, also known as lithium polymer batteries (Li-PoBattery), are thin lithium-ion batteries that use a flexible aluminum-plastic composite casing and a lithium-ion electrolyte. Because the aluminum-plastic film casing of soft-pack batteries is very thin and flexible, its surface is easily damaged during production and handling. Currently, trays are commonly used for loading and handling batteries; however, existing tray structures, while compatible with various battery cell sizes, are generally complex, with cumbersome assembly and disassembly processes. Single-size trays, on the other hand, are incompatible with different battery cell sizes, resulting in poor compatibility. Therefore, there is an urgent need for a simple and compatible tray structure suitable for soft-pack batteries. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a fully functional adjustable soft-pack battery cell tray.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a fully functional adjustable soft-pack battery cell tray, including a front fixed plate and a rear fixed plate arranged opposite to each other. A left partition group and a right partition group are respectively provided on the left and right sides between the front and rear fixed plates. Each left and right partition group includes multiple partitions arranged in parallel, and the partitions of the left and right partition groups are arranged opposite to each other. Adjacent partitions of the left partition group form a left clamping cavity for the battery cell, and adjacent partitions of the right partition group form a right clamping cavity for the battery cell. The left and right sides of the battery cell are clamped in the left and right clamping cavities respectively. The partitions of the left partition group are connected between the front and rear fixed plates by multiple connecting rods passing through them, and the partitions of the right partition group are connected between the front and rear fixed plates by multiple connecting rods passing through them. The end of each connecting rod can be locked with a nut fastener. By changing the size of the partitions, the width of the left and right clamping cavities can be adjusted to accommodate soft-pack battery cells of different thicknesses.

[0005] Furthermore, the partition includes a base, a clamping plate, and a side connecting block. The base has at least two through holes for connecting the connecting rod. The bottom of the clamping plate is fixed to the top of the base, and the upper end of the clamping plate extends outward to connect to the side connecting block. The side connecting block has at least one through hole for connecting the connecting rod.

[0006] Furthermore, vertically extending limiting strips are provided on both the front and rear sides of the clamping plate. These are used to limit and position the battery cell.

[0007] Furthermore, to reduce the overall weight of the tray, the base adopts a hollow design with multiple weight-reducing holes. The size and shape of the weight-reducing holes can vary.

[0008] Furthermore, to facilitate use with automated production lines, a front limiting plate is provided at the bottom front side of the front fixed plate, and a rear limiting plate is provided at the bottom rear side of the rear fixed plate. The front limiting plate and the rear limiting plate are respectively fixed to the front fixed plate and the rear fixed plate by screws, which are used for stopping and limiting the automated line, enhancing the strength of the pallet and extending its service life.

[0009] Furthermore, to reduce the space occupied during placement, the trays can be stacked. Therefore, to ensure stability during stacking, both the front and rear fixing plates are provided with limiting protrusions at their tops, and limiting grooves matching the limiting protrusions are provided at their bottoms. During stacking, the limiting protrusions of the lower layer are embedded into the limiting grooves of the upper layer. The limiting protrusions and limiting grooves cooperate to limit the stacking of the robotic arm.

[0010] Furthermore, the front fixed plate has two front gripping positions for robotic arms on its front side, and the rear fixed plate has two rear gripping positions for robotic arms on its rear side. The front and rear gripping positions of the robotic arms work together to allow the robotic arms to grip the entire pallet, facilitating movement and stacking.

[0011] Furthermore, at least a portion of the edge of the front side of the front fixing plate has a forward-extending flange; at least a portion of the edge of the rear side of the rear fixing plate has a rearward-extending flange.

[0012] The beneficial effects of this utility model are: This utility model provides a fully functional adjustable soft-pack battery cell tray, which can accommodate battery cells of different sizes by adjusting the nut fasteners and replacing the partition. After placing the battery cell, it is tightened and finally the limiting plate is locked, which meets the needs of automated production line; and the structure is simple and the installation and disassembly are convenient and quick.

Therefore, they only show the components, orientations, and references (e.g., up, down, left, right, etc.) relevant to the present invention and are intended only to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0022] like Figures 1-5As shown, this utility model discloses a fully adjustable soft-pack battery cell tray, comprising a front fixing plate 1 and a rear fixing plate 2 arranged opposite to each other. A left partition group 3 and a right partition group 4 are respectively provided on the left and right sides between the front fixing plate 1 and the rear fixing plate 2. Both the left partition group 3 and the right partition group 4 include multiple partitions 5 arranged in parallel, and the partitions 5 of the left partition group 3 and the right partition group 4 are arranged opposite to each other. The left clamping cavity 7 of the battery cell 6 (yellow part in the figure) is formed between the adjacent partitions 5 of the left partition group 3, and the right clamping cavity 8 of the battery cell 6 is formed between the adjacent partitions 5 of the right partition group 4. The left and right sides of the battery cell 6 are clamped in the left clamping cavity 7 and the right clamping cavity 8, respectively. The partitions 5 of the left partition group 3 are connected between the front fixing plate 1 and the rear fixing plate 2 by multiple connecting rods 9 passing through them, and the partitions 5 of the right partition group 4 are connected between the front fixing plate 1 and the rear fixing plate 2 by multiple connecting rods 9 passing through them. The end of each connecting rod 9 (blue part in the figure) can be locked by a nut fastener 10. The connecting rods 9 can have a variety of different lengths. By changing the size of the partitions 5, the width of the left clamping cavity 7 and the right clamping cavity 8 can be adjusted to accommodate soft-pack battery cells 6 of different thicknesses. The front fixing plate 1 has a forward-extending flange 14 on at least a portion of its front side edge; the rear fixing plate 2 has a rearward-extending flange 14 on at least a portion of its rear side edge.

[0023] like Figure 1 and Figure 2 As shown, the front fixed plate 1 has a front limiting plate 13 (pink part in the figure) at its front bottom, and the rear fixed plate 2 has a rear limiting plate (not shown in the figure) at its rear bottom. The front limiting plate 13 and the rear limiting plate are fixed to the front fixed plate 1 and the rear fixed plate 2 respectively by screws, used for stopping and limiting the automated line, enhancing the strength of the pallet and extending its service life. The top of the front fixed plate 1 and the rear fixed plate 2 are provided with limiting protrusions 11, and the bottom of the front fixed plate 1 and the rear fixed plate 2 are provided with limiting grooves that match the limiting protrusions 11. When stacked, the limiting protrusions 11 of the lower layer are embedded in the limiting grooves of the upper layer. The limiting protrusions 11 and the limiting grooves cooperate with each other for the stacking and limiting of the robot arm. The front side of the front fixed plate 1 has two robot arm front gripping positions 12, and the rear side of the rear fixed plate 2 has two robot arm rear gripping positions (not shown in the figure). The robot arm front gripping positions 12 and the robot arm rear gripping positions cooperate to allow the robot arm to grasp the pallet as a whole, facilitating movement and stacking.

[0024] like Figure 6As shown, the partition 5 includes a base 5.1, a clamping plate 5.2, and a side connecting block 5.3. The base 5.1 has at least two through holes 5.4 for connecting the connecting rods 9. The bottom of the clamping plate 5.2 is fixed to the top of the base 5.1, and the upper end of the clamping plate 5.2 extends outward to connect to the side connecting block 5.3. The side connecting block 5.3 has at least one through hole 5.4 for connecting the connecting rods 9. The width of the base 5.1 and the side connecting block 5.3 can be adjusted according to the thickness of the battery cell 6 to be clamped. Therefore, various sizes of partitions 5 can be used to accommodate battery cells 6 of different thicknesses. In this embodiment, the base 5.1 has two through holes 5.4 for connecting two connecting rods 9, and the side connecting block 5.3 has one through hole 5.4 for connecting one connecting rod 9. The three connecting rods 9 form a stable connection support structure. Vertically extending limiting strips 5.6 are provided on the front and rear sides of the clamping plate 5.2 for limiting and positioning the battery cell 6. The base 5.1 adopts a hollow design and has multiple weight-reducing holes 5.5. The size and shape of the weight-reducing holes 5.5 may vary.

[0025] Working principle:

[0026] First, based on the thickness of the battery cell 6, select multiple partitions 5 of appropriate thickness and size. Based on the weight of the battery cell 6 and the load-bearing capacity of the connecting rod 9, select a connecting rod 9 of appropriate length. Next, pass the connecting rod 9 through the connecting holes on the partition 5, with one connecting rod 9 at the top and two connecting rods 9 at the bottom. Then, connect the front end of the connecting rod 9 to the front fixing plate 1 and pre-tighten it with a nut fastener 10. Connect the rear end of the connecting rod 9 to the rear fixing plate 2 and pre-tighten the end with a nut fastener 10 as well. Next, place the battery cells 6 one by one into the left clamping cavity 7 and right clamping cavity 8 formed by the partition 5. The bottom of the battery cell 6 is supported by the base 5.1 of the partition 5. Next, tighten the nut fastener 10, thereby clamping and fixing the battery cell 6 through the clamping plate 5.2. Finally, attach the limiting plate to the lower part of the front and rear fixing plates 2 to facilitate the positioning of the automated line.

[0027] After the battery cells 6 are loaded onto a tray, they are held in the front and rear gripping positions of the robotic arm by the robotic arm for circulation and stacking. During stacking, the limiting protrusions 11 on the top of the front fixing plate 1 and the limiting grooves on the bottom cooperate to achieve stacking positioning.

[0028] When disassembly is required, simply unscrew the nut fastener 10, then pull out the connecting rod 9, and the entire tray can be disassembled. Disassembly is convenient and quick.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
