Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, and in particular to a battery cell stacking and extrusion equipment adaptable to multiple lengths. Background Technology

[0002] In the manufacturing process of lithium-ion batteries and other types of batteries, cell stacking is one of the key steps to ensure the performance and safety of battery modules or packs. This process typically involves tightly arranging and securing multiple individual cells (such as pouch cells or prismatic cells) together in a specific order and manner. To achieve optimal electrical performance, thermal management, and mechanical stability, specialized cell stacking extrusion equipment is required to apply appropriate mechanical pressure to keep the cells tightly bonded together.

[0003] While existing cell stacking and extrusion equipment can meet production needs to a certain extent, there are still some problems in actual use. Because existing cell stacking and extrusion equipment lacks an adaptive positioning mechanism for cell length, the cells are mainly aligned manually during the stacking process, which can easily lead to misalignment of the cell sides. This not only affects the appearance quality but may also cause safety hazards such as poor internal contact or short circuits.

[0004] To address the aforementioned issues, we propose a battery cell stacking and extrusion device that can adapt to multiple cell lengths. This device can automatically perform adaptive positioning based on the specific length of the battery cell, ensuring that each side of the cell is precisely aligned. Utility Model Content

[0005] To overcome the shortcomings of existing battery cell stacking and extrusion equipment, which lacks an adaptive positioning mechanism for battery cell length and is prone to misalignment of battery cell sides when placed manually, the technical problem to be solved is to provide a battery cell stacking and extrusion equipment that can adapt to multiple lengths. This battery cell stacking and extrusion equipment can automatically perform adaptive positioning according to the specific length of the battery cell, ensuring that all sides of each battery cell can be accurately aligned.

[0006] The technical solution of this utility model is: a battery cell stacking and extrusion device adaptable to multiple lengths, including a base, a driving component fixedly connected to one side of the base, a movable pressure plate fixedly connected to the telescopic end of the driving component, a fixed pressure plate fixedly connected to the other side of the base, two longitudinally symmetrical fixed seats fixedly connected to the other side of the base, a bidirectional screw rotatably connected between the two fixed seats, a guide frame fixedly connected to the base, two longitudinally symmetrical first positioning plates slidably connected to the guide frame, the first positioning plates and the bidirectional screw are connected by threads, the first positioning plates are provided with positioning components for positioning and aligning the upper side of the battery cell, and a fixing component is provided on the base for fixing the base in a designated position.

[0007] Furthermore, a turntable is fixedly connected to the bidirectional screw.

[0008] Furthermore, the positioning assembly includes a first sliding frame, which is slidably connected to a first positioning plate. A pressing frame is fixedly connected to the outside of the first sliding frame. Two first springs, symmetrically arranged laterally, are fixedly connected between the first sliding frame and the adjacent first positioning plate. A long support rod is connected to one side of the first positioning plate, and a short support rod is fixedly connected to the other side of the first positioning plate. A second positioning plate is rotatably connected between the short support rod and the adjacent long support rod. A torsion spring is connected between the second positioning plate and the long and short support rods. A second sliding frame is slidably connected to the second positioning plate, and two second springs, symmetrically arranged laterally, are connected between the second sliding frame and the second positioning plate.

[0009] Furthermore, the second positioning plate has two horizontally symmetrical right-angle protrusions on the side near the extrusion frame, and the end of the extrusion frame near the right-angle protrusion is wedge-shaped, and the extrusion frame and the second positioning plate are pressed together.

[0010] Furthermore, the fixing component includes guide rods, which are fixedly connected to the four corners of the base. Clamping plates are slidably connected to the guide rods, and threaded rods are rotatably connected to the four corners of the base. The threaded rods are threadedly connected to the adjacent clamping plates.

[0011] Furthermore, the clamping plate has a right-angle structure, which is used to fit the corners of the processing table.

[0012] This invention has the following advantages: Battery cells are stacked on a base. A bidirectional screw rotates to control the first positioning plate to slide inwards and position the front and rear sides of the battery cells. The second positioning plate rotates downwards to position the upper side of the battery cells. Under the action of the extension and retraction of the second spring, the second sliding frame can slide to adapt to the height of the battery cells, while the first positioning plate can freely adjust its movement distance to adapt to the width of the battery cells. After the battery cells are aligned, a driving component controls the movable pressure plate to slide to the right. The movable pressure plate slides to the right and cooperates with the fixed pressure plate to squeeze the battery cells, making them tightly arranged and fixed together. In this way, adaptive positioning can be automatically performed according to the specific length of the battery cells, ensuring that each side of each battery cell is precisely aligned.

Detailed Implementation

[0020] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0021] Example 1: A multi-length battery cell stacking and extrusion device, such as... Figures 1-6 As shown, the device includes a base 1, a drive component 2, a movable pressure plate 3, a fixed pressure plate 4, a fixed seat 5, a bidirectional screw 6, a guide frame 7, a first positioning plate 8, a positioning assembly, and a fixing assembly. The drive component 2 is fixedly connected to the left side of the base 1, and the movable pressure plate 3 is fixedly connected to the telescopic end of the drive component 2. The fixed pressure plate 4 is fixedly connected to the right side of the base 1, and two symmetrical fixed seats 5 are fixedly connected to the right side of the base 1. The bidirectional screw 6 is rotatably connected between the two fixed seats 5, and a turntable is fixedly connected to the rear end of the bidirectional screw 6. The guide frame 7 is fixedly connected to the left side of the base 1, and two symmetrical first positioning plates 8 are slidably connected to the guide frame 7. The right side of the first positioning plate 8 is threadedly connected to the bidirectional screw 6. The first positioning plate 8 is provided with a positioning assembly for positioning and aligning the upper side of the battery cell. The base 1 is provided with a fixing assembly for fixing the base 1 in a designated position.

[0022] When using the device, the operator fixes the base 1 to the processing table using the fixing component, and then stacks the battery cells on the base 1 so that the battery cells are located between the movable pressure plate 3 and the fixed pressure plate 4. After placement, the operator controls the rotation of the bidirectional screw 6. The rotation of the bidirectional screw 6 drives the two front and rear first positioning plates 8 to slide inward. The sliding of the first positioning plates 8 inward positions the front and rear sides of the battery cells. After the first positioning plates 8 slide inward, the positioning component also positions the upper side of the battery cells. Then, the operator controls the movable pressure plate 3 to slide to the right using the drive component 2. The sliding of the movable pressure plate 3 to the right cooperates with the fixed pressure plate 4 to squeeze the battery cells, so that the battery cells are tightly arranged and fixed together.

[0023] Example 2: Based on Example 1, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the positioning assembly includes a compression frame 9, a first sliding frame 91, a first spring 10, a long support rod 11, a short support rod 111, a second positioning plate 12, a torsion spring 13, a second sliding frame 14, and a second spring 15. The first sliding frame 91 is slidably connected to the first positioning plate 8, and the compression frame 9 is fixedly connected to the outside of the first sliding frame 91. Two first springs 10 are fixedly connected symmetrically between the first sliding frame 91 and the adjacent first positioning plate 8. The long support rod 11 is connected to the right side of the first positioning plate 8, and the short support rod 11 is fixedly connected to the left side of the first positioning plate 8. 1. A second positioning plate 12 is rotatably connected between the short support rod 111 and the adjacent long support rod 11. The second positioning plate 12 has two transversely symmetrical right-angle protrusions on the side near the extrusion frame 9. The end of the extrusion frame 9 near the right-angle protrusion is wedge-shaped. The extrusion frame 9 and the second positioning plate 12 are press-fitted together. A torsion spring 13 is connected between the second positioning plate 12, the long support rod 11, and the short support rod 111. A second sliding frame 14 is slidably connected to the second positioning plate 12. Two second springs 15 are symmetrically connected between the second sliding frame 14 and the second positioning plate 12.

[0024] When using this device, the first positioning plate 8 slides inward, causing the entire positioning assembly to move inward together. When the first sliding frame 91 moves inward to contact the battery cell, the first sliding frame 91 is squeezed outward by the battery cell, causing the first spring 10 to deform. The first sliding frame 91 slides outward, causing the compression frame 9 to move outward. The compression frame 9 moves outward, squeezing the second positioning plate 12 to rotate downward. After rotating downward, the second positioning plate 12 is in a flat position. The upper side of the battery cell is positioned by the second positioning plate 12. Under the action of the extension and retraction of the second spring 15, the second sliding frame 14 can slide to adapt to the height of the battery cell. The first positioning plate 8 and the second positioning plate 12 respectively position the front and rear sides and the upper side of the battery cell, so that the battery cells are arranged neatly and the stacking assembly quality is ensured.

[0025] like Figure 1 and Figure 6 As shown, the fixing assembly includes a clamping plate 16, a guide rod 17, and a threaded rod 18. The guide rod 17 is fixedly connected to the left and right sides of the front and rear sides of the base 1. The clamping plate 16 is slidably connected to the guide rod 17. The clamping plate 16 has a right-angle structure and is used to fit the corner of the processing table. The threaded rod 18 is rotatably connected to the left and right sides of the front and rear sides of the base 1. The threaded rod 18 is connected to the adjacent clamping plate 16 by threads.

[0026] When using the device, the operator places it on the processing table, with the clamping plate 16 positioned on the front and back sides of the processing table. Then, by rotating the threaded rod 18, the operator controls the clamping plate 16 to move inward. After the clamping plate 16 moves inward, it clamps the processing table, thereby fixing the device on the processing table. This prevents the device from shifting position and affecting the processing operation when stacking and extruding battery cells.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
