Description

Technical Field

[0001] This utility model relates to the field of compaction equipment technology, and in particular to a compaction device for soft-pack lithium batteries. Background Technology

[0002] Soft-pack lithium batteries are one type of lithium battery, essentially liquid lithium-ion batteries encased in a polymer shell. Structurally, they are packaged in an aluminum-plastic film. In the event of a safety hazard, a soft-pack battery will at most swell and crack. Soft-pack lithium batteries offer advantages such as good safety performance, light weight, large capacity, low internal resistance, and flexible design. However, during processing, soft-pack lithium batteries require compaction to expel air and reduce internal gaps. Current compaction equipment requires manual unloading of the compacted batteries and placement of the next battery to be processed, a cumbersome process that reduces processing efficiency. Utility Model Content

[0003] This utility model discloses a compaction device for soft-pack lithium batteries, which solves the problem of cumbersome operation and low processing efficiency caused by manually unloading the compacted soft-pack lithium batteries and then manually placing the soft-pack lithium batteries to be processed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A compaction device for soft-pack lithium batteries includes a support base, a worktable fixed on the support base, a hydraulic rod that can move laterally above the worktable, and a pressure plate fixed to the telescopic end of the hydraulic rod; a movable plate that can move laterally and push the lithium battery is provided on the worktable, and a drive assembly for driving the hydraulic rod is provided on the support base.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] Two pouch lithium batteries can be placed sequentially on a worktable. Through the lateral movement of a hydraulic rod, after one pouch lithium battery is compacted by a pressure plate driven by the hydraulic rod, the pressure plate moves laterally above the other pouch lithium battery to begin compacting it. A moving plate then moves laterally to push the compacted pouch lithium battery off the worktable, completing the unloading of the pouch lithium batteries. Simultaneously, the operator can load the pouch lithium batteries to be compacted. This invention eliminates the need for manual unloading and machine shutdown. While one pouch lithium battery is being processed, the other can be loaded. The operation is simple and fast, improving the processing efficiency of pouch lithium batteries.

[0011] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 and Figure 2 As shown, this utility model provides a compaction device for soft-pack lithium batteries, including a support base 1, a workbench 2 fixed on the support base 1, a hydraulic rod 4 that can move laterally above the workbench 2, and a pressure plate 41 fixed to the telescopic end of the hydraulic rod 4; a moving plate 3 that can move laterally and push the lithium battery is provided on the workbench 2, and a drive assembly for driving the hydraulic rod 4 is provided on the support base 1. After placing two pouch lithium batteries on workbench 2, the drive assembly can be activated to move the hydraulic rod 4 directly above one pouch lithium battery. Then, the hydraulic rod 4 drives the pressure plate 41 downward to compact the pouch lithium battery. Once one pouch lithium battery is compacted, the drive assembly moves the hydraulic rod 4 directly above the other pouch lithium battery. Simultaneously, the moving plate 3 moves laterally to push the compacted pouch lithium battery off workbench 2, completing the unloading operation. While another pouch lithium battery is being compacted, the operator can place other pouch lithium batteries to be compacted on workbench 2 without stopping the machine for loading and unloading. The above operations can then be repeated to complete the compaction and unloading of the pouch lithium batteries.

[0013] like Figure 1As shown, the drive assembly includes a motor 7 fixed on the support base 1. A lead screw 71 is fixed on the shaft of the motor 7. A connecting plate 72, which is slidably connected to the support base 1, is threaded onto the lead screw 71. A movable frame 5, which is fixed to the hydraulic rod 4, is fixed on one side of the connecting plate 72. The motor 7 is a servo motor. The worktable 2 is U-shaped. One end of the lead screw 71 is rotatably connected to one side of the worktable 2. After the motor 7 is started and the lead screw 71 rotates, the connecting plate 72 can drive the hydraulic rod 4 to move laterally through the movable frame 5. After the hydraulic rod 4 moves the pressure plate 41 to directly above the soft-pack lithium battery, the telescopic end of the hydraulic rod 4 can drive the pressure plate 41 to move downward to compact the soft-pack lithium battery. The fixed end of the hydraulic rod 4 is fixed to the top of the movable frame 5. The movable frame 5 is L-shaped, and the bottom of the movable frame 5 is slidably connected to the top of the support base 1.

[0014] like Figure 1 and Figure 2 As shown, the workbench 2 has an opening 21, and a fixed plate 31 passing through the opening 21 is fixed to the bottom of the movable plate 3. There are two movable plates 3, which are symmetrically distributed from left to right. The workbench 2 is equipped with two electric telescopic rods 6, and the telescopic ends of the two electric telescopic rods 6 are respectively fixed to the two fixed plates 31. Two soft-pack lithium batteries can be placed on the opposite sides of the two movable plates 3, and the two movable plates 3 can also play a role in positioning the soft-pack lithium batteries. When the connecting plate 72 drives the movable frame 5 to move to the left (towards... Figure 1 (As shown in the diagram), the pressure plate 41 is positioned directly above the left-side soft-pack lithium battery. The hydraulic rod 4 drives the pressure plate 41 to process the soft-pack lithium battery. After the soft-pack lithium battery is processed, the telescopic end of an electric telescopic rod 6 drives the movable plate 3 on the left side away from the other movable plate 3 via the fixed plate 31, so that the processed soft-pack lithium battery on the left side can be pushed off the workbench 2. After the processed soft-pack lithium battery is restored, the pressure plate 41 moves to directly above the right-side soft-pack lithium battery to begin processing it. The operator can then place the soft-pack lithium battery to be processed on the left side of the top of the workbench 2 without stopping the machine to load and unload. The fixed plate 31 is U-shaped and is slidably connected in the opening 21.

[0015] like Figure 1 and Figure 2 As shown, the top of the workbench 2 is fixed with two symmetrically positioned limiting plates 8. Two movable plates 3 are located inside the two limiting plates 8 respectively. The limiting plates 8 and the movable plates 3 can cooperate with each other, contacting both sides of the soft-pack lithium battery to effectively position the battery and prevent it from tilting. When the pressure plate 41 moves downwards to compact the soft-pack lithium battery on the left side of the workbench 2, the back and right sides of the pressure plate 41 (as shown) Figure 1(as shown in the diagram) it contacts the front of the limiting plate 8 and the left side of the moving plate 3 located on the left, respectively, without affecting the normal descent of the pressure plate 41.

[0016] like Figure 1 As shown, inclined feeding plates 9 are fixed on both sides of the workbench 2. When the compacted soft-pack lithium battery is pushed onto the feeding plate 9, the soft-pack lithium battery can slide down, avoiding damage caused by the soft-pack lithium battery falling directly from a height.

[0017] like Figure 1 As shown, a heating plate 42 is embedded in the bottom of the pressure plate 41, and a pressing sheet 43 connected to the bottom of the heating plate 42 is fixed to the bottom of the pressure plate 41. The heating plate 42 is a square-shaped, safe and reliable electric heating plate that heats up when energized but does not carry electricity or open flame. Since it mainly relies on heat conduction during use, it has high thermal efficiency. The heat generated by the heating plate 42 is absorbed by the pressing sheet 43, thereby increasing the temperature of the pressing sheet 43 itself. When the pressing sheet 43 moves downward with the pressure plate 41 to compact the soft-pack lithium battery, the high temperature allows the soft-pack lithium battery to be better shaped.

[0018] In use, place two soft-pack lithium batteries on top of the worktable 2, ensuring that each battery contacts the opposite side of the two moving plates 3. Then, move the hydraulic rod 4 to the left side of the worktable 2. Figure 1 After the soft-pack lithium battery is positioned directly above the workbench 2 (as shown in the diagram), the hydraulic rod 4 drives the pressure plate 41 to move downwards to compact the soft-pack lithium battery. After compaction, the hydraulic rod 4 drives the pressure plate 41 to return to its original position. When the hydraulic rod 4 moves towards the soft-pack lithium battery on the right side of the workbench 2, an electric telescopic rod 6 drives the fixed plate 31 to move the moving plate 3 on the left side, pushing the processed soft-pack lithium battery off the workbench 2. When the moving plate 3 returns to its original position, while the pressure plate 41 is compacting the soft-pack lithium battery on the right side, the worker can place the soft-pack lithium battery to be processed on the left side of the workbench 2. The above operations are repeated, with the hydraulic rod 4 moving laterally and the two moving plates 3 moving alternately, which can quickly compact the soft-pack lithium battery. When it is necessary to compact a large soft-pack lithium battery, the two moving plates 3 can be moved away from each other, and the soft-pack lithium battery can be placed between the two moving plates 3 to position the soft-pack lithium battery. Then, the hydraulic rod 4 drives the pressure plate 41 to move downward to compact the soft-pack lithium battery. Furthermore, by moving the hydraulic rod 4 laterally, the pressure plate 41 can compact the large soft-pack lithium battery from all directions.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
