Description

Technical Field

[0001] This utility model relates to the technical field of batteries, and in particular to a battery stacking platform. Background Technology

[0002] The existing battery cell production process includes a lamination process. After lamination, the stacked cells are placed on a platform where the position of the stacked cells is adjusted by the partitions installed on the four sides of the platform. This prevents the accumulated stacked cells from tipping over and collapsing. During loading, the platform has a cavity in the middle, from which a support rod extends to lift the stacked cells upwards before they are transferred by a suction mechanism. During the rising process, the edges of the stacked cells or electrodes may rub against the partitions around the platform, potentially damaging the edges of the stacked cells and affecting the safety of the stacked cells. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a battery stacking platform to solve the problem of edge wear that may occur during the transfer of battery cell stacks.

[0004] Based on the technical problems existing in the background art, this utility model proposes a battery stacking platform, including a working platform and a carrying platform. The working platform and the carrying platform are connected by a chain. The chain is supported by a steering mechanism set on the working platform. The working platform is equipped with a lifting mechanism connected to the steering mechanism. The operation of the lifting mechanism drives the steering mechanism to rise and fall, and makes the working platform rise and fall horizontally.

[0005] In the above scheme, the platform is used to stack the wafers. The corners of the wafers are kept regular by the chain. During the process of the platform rising, the chain and the wafers can remain relatively stationary to avoid friction, which can reduce the wear of the wafers and improve the safety of cell manufacturing.

[0006] Preferably, the steering mechanism includes rollers and a rod, with rollers rotatably connected to both ends of the rod. The rollers support the chain from bottom to top and cause the chain to turn.

[0007] In the above scheme, when the entire steering mechanism is raised or lowered, the rod and rollers will support the chain. When the entire steering mechanism moves upward, the rollers can turn the chain and pull the cargo platform upward.

[0008] Preferably, multiple support rods are fixed on the working platform, and a horizontally placed limiting plate is connected to the upper end of each support rod. A stabilizing rod is slidably installed on the limiting plate, and the top end of the stabilizing rod is connected to the rod body.

[0009] In the above scheme, the stabilizer bar can slide longitudinally relative to the limiting plate. After the stabilizer bar is connected to the bar body, it can stabilize the bar body, so that the bar body can only slide longitudinally.

[0010] Preferably, the chain includes multiple chain blocks, each with an L-shaped cross-section. The chain blocks are sequentially hinged to form vertical corner slots. Stacked pieces are placed on the loading platform with the corners corresponding to the corner slots.

[0011] In the above scheme, the chain block can form a vertical strip shape, the corner grooves of the chain block face inward, the corners of the stacked pieces can be placed in the corresponding corner grooves, and the corner grooves can limit the tilt of the stacked pieces.

[0012] Preferably, a protrusion is provided above the chain block, and a concave body corresponding to the protrusion is provided below the chain block. When the chain blocks form a chain, the protrusions and corresponding concave bodies of adjacent chain blocks engage.

[0013] In the above scheme, the protrusion provided above the chain allows the topmost stacked piece to still have a restraining effect, preventing the topmost stacked piece from tilting or shifting.

[0014] Preferably, the chain block has a key on the side facing the support rod, and the roller has teeth on its surface that mesh with the key of the chain block. The lifting and lowering of the rod can cause the roller to rotate.

[0015] In the above scheme, the teeth of the chain block and the teeth on the roller can strengthen the meshing between them, which can improve the overall stability of operation.

[0016] Preferably, multiple chains can keep the cargo platform parallel to the ground.

[0017] In the above scheme, keeping the loading platform parallel to the ground enables the loading platform to remain level when carrying objects, prevents objects from tilting and causing uneven weight distribution, and improves the stability of the entire mechanism.

[0018] Preferably, the lifting mechanism is connected to the middle of the rod. In this design, the weight of the rod is located at the center of the rod, which can better transfer the weight to the lifting mechanism.

[0019] Compared with the prior art, the battery stacking platform proposed in this utility model adopts the above-mentioned technical solution and achieves the following technical effects:

[0020] In this invention, the carrying platform can drive the stacked wafers to rise and fall, and the wafers and the chain at the same level can rise and fall synchronously. The wafers can avoid friction with the chain, reduce the loss of the wafers during the rising and falling process, and thus improve the safety of battery cell production. Attached Figure Description

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature. Example

[0026] Please refer to Figures 1-2 This utility model proposes a battery stacking platform, including a working platform 1 and a carrying platform 2. The working platform 1 and the carrying platform 2 are connected by a chain 4. The chain 4 is supported by a steering mechanism 5 provided on the working platform 1. The working platform 1 is provided with a lifting mechanism 6 connected to the steering mechanism 5. The operation of the lifting mechanism 6 drives the steering mechanism 5 to rise and fall, and allows the working platform 1 to rise and fall horizontally. In this solution, the stacked cells can be placed on the carrying platform 2 for stacking. The carrying platform 2 is suspended by the chain 4. When the lifting mechanism 6 is running, since one end of the chain 4 is fixed, the end of the chain 4 connected to the carrying platform 2 will be pushed up, which can drive the stacked cells to rise. Furthermore, the position of the chain 4 at the same horizontal position as the carrying platform 2 will rise together with the lifting of the carrying platform 2. When the chain 4 reaches a certain height, it will be turned by the steering mechanism 5 to always avoid relative displacement between the chain 4 and the stacked cells, thereby avoiding friction between the chain 4 and the stacked cells and reducing wear on the stacked cells.

[0027] In a specific embodiment, refer to Figure 1 , Figure 2 The steering mechanism 5 includes rollers 51 and a rod 52. Both ends of the rod 52 are rotatably connected to rollers 51. The rollers 51 support the chain 4 from bottom to top and cause the chain 4 to turn. In this scheme, the lifting mechanism 6 is connected to the middle of the rod 52. The center of the weight borne by the rod 52 will fall on the lifting mechanism 6. The rollers 51 can reduce the friction between the chain 4 and the rod 52, which facilitates the turning of the chain 4. The rollers 51 have a supporting effect on the chain 4.

[0028] In a specific embodiment, refer to Figure 1 , Figure 2 The working platform 1 has multiple support rods 3 fixed on it. The upper end of each support rod 3 is connected to a horizontally placed limiting plate 31. A stabilizing rod 32 is slidably installed on the limiting plate 31, and the top end of the stabilizing rod 32 is connected to the rod body 52. ​​In this solution, the limiting plate 31 can restrict the sliding of the stabilizing rod 32, so that the stabilizing rod 32 only slides longitudinally. There can be multiple limiting plates 31, all of which are connected to the support rods 3, which can increase the stability of the stabilizing rod 32. After the stabilizing rod 32 is connected to the rod body 52, the rod body 52 can move longitudinally like the stabilizing rod 32, without generating lateral force. This can reduce the lifting mechanism 6 from overcoming lateral force and improve the stability of the mechanism. The stabilizing rod 32 and the support rod 3 in this application both have a certain length.

[0029] In a specific embodiment, refer to Figure 1 , Figure 2 The chain 4 includes multiple chain blocks 41, each with an L-shaped cross-section. The chain blocks 41 are hinged together to form vertical corner grooves 42. Stacked pieces are placed on the loading platform 2 with the corners corresponding to the corner grooves 42. In this design, the chain blocks 41 are relatively rigid, and the chain 4 can also be made of rubber. The chain blocks 41 can facilitate the steering of the steering mechanism 5. Each chain block 41 has a corner groove 42, which is used to limit the position of the stacked pieces, prevent the stacked pieces from tipping over, and increase the stability of the stacked pieces.

[0030] In a specific embodiment, refer to Figure 1 , Figure 2 A protrusion 411 is provided above the chain block 41, and a corresponding concave-convex part is provided below the chain block 41. When the chain block 41 forms the chain 4, the protrusions 411 of adjacent chain blocks 41 engage with the corresponding concave parts 412. In this solution, when the chain block 41 turns, the top plate may not be laterally limited. Therefore, a protrusion 411 is provided at the top of the chain block 41 to limit the topmost plate and prevent the plate from tilting and falling.

[0031] In a specific embodiment, refer to Figure 1 , Figure 2The chain block 41 has a toothed key on the side facing the support rod 3, and the surface of the roller 51 has teeth that mesh with the toothed key of the chain block 41. The lifting and lowering of the rod 52 can drive the roller 51 to rotate. In this solution, the chain block 41 and the roller 51 are meshed by the toothed key to increase the friction or biting effect between them, which makes the chain 4 formed by the chain block 41 move more conveniently.

[0032] In a specific embodiment, refer to Figure 1 , Figure 2 Multiple chains 4 can keep the loading platform 2 parallel to the ground. The chains 4 are of the same length and the rollers 51 are of the same height. When the loading platform 2 is kept parallel to the ground, the stacked pieces can be placed more stably.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
