Description

Technical Field

[0001] This utility model relates to the field of lithium battery core cutting technology, and more specifically, to a manufacturing equipment for a stacked lithium battery core structure. Background Technology

[0002] With the rapid development of the new energy industry, lithium batteries, as a high-efficiency and environmentally friendly energy storage device, have been widely used in electric vehicles, portable electronic devices, and other fields. In lithium battery manufacturing technology, the core structure is one of the key factors affecting battery performance. Due to its better energy density, safety, and charge / discharge performance, the stacked lithium battery core structure has gradually become a research hotspot and development direction in the field of lithium battery manufacturing.

[0003] Current lithium battery core cutting equipment uses electric cylinders to drive blades to cut lithium battery cores. When the cutting blades cut lithium battery cores for a long time, the lifespan of the cutting blades is shortened, resulting in very rough lithium battery cores. This not only increases costs but also affects production efficiency. Therefore, a stacked lithium battery core structure manufacturing equipment is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a manufacturing equipment for a stacked lithium battery core structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a manufacturing equipment for a stacked lithium battery core structure, comprising two limiting plates. Each limiting plate has a sliding groove at its midpoint on an opposite side. Two arc-shaped sliding holes are formed within each sliding groove and are positioned far apart from each other. A cutting assembly is provided on each limiting plate. The cutting assembly includes two sliding plates, both sides of which slide within the sliding grooves on opposite sides of the limiting plates. A first rotating column is slidably connected within each arc-shaped sliding hole, with one end of the first rotating column fixedly connected to one side of a sliding plate. A second rotating column is fixedly connected at its midpoint on opposite sides of each limiting plate. A first rotating bar is rotatably connected to the outer side of each second rotating column, with the second rotating column located at the center of the first rotating bar. A third rotating column is fixedly connected to one side of the first rotating bar near both ends, with a second rotating bar rotatably connected to the outer side of each third rotating column.

[0006] As a further improvement to this technical solution, a receiving plate is fixedly connected to the top side of the two limiting plates, and a driving cylinder is fixedly installed at the center position of the top side of the receiving plate. The piston rod end of the driving cylinder is fixedly connected to the top side of one of the sliding plates.

[0007] As a further improvement to this technical solution, cutting blades are fixedly installed on the opposite side of the two sliding plates. The two cutting blades are staggered from each other. When the two cutting blades move towards each other, they cut the lithium battery core.

[0008] As a further improvement to this technical solution, when the driving cylinder drives one of the sliding plates to slide between the two limiting plates, the two first rotating columns drive the two second rotating bars to squeeze one of the third rotating columns, causing the first rotating bar to rotate on the outside of the second rotating column. At the same time, the other third rotating column squeezes the other second rotating bar, and the other second rotating bar drives the other sliding plate to slide between the two limiting plates through one of the first rotating columns.

[0009] As a further improvement to this technical solution, a fixing plate is fixedly connected to the opposite side of the two limiting plates near the bottom, and a fixing hole is opened in the middle of the top side of the two fixing plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In the manufacturing equipment for stacked lithium battery core structures, the cutting blades become jerky due to prolonged cutting of the lithium battery cores. A drive cylinder drives one of the sliding plates to slide between two limiting plates. Two first rotating columns drive two second rotating strips to press against one of the third rotating columns, causing the first rotating strips to rotate on the outside of the second rotating column. Simultaneously, another third rotating column presses against another second rotating strip. Then, another second rotating strip, through one of the first rotating columns, drives another sliding plate to slide between the two limiting plates. Finally, when the two sliding plates drive the two cutting blades to move towards each other, the lithium battery core is cut, resulting in double-sided cutting of the lithium battery core. This increases cutting efficiency and extends the service life of the cutting blades. Attached Figure Description

[0019] Example 1

[0020] Please see Figures 1-3As shown, this embodiment provides a manufacturing equipment for a stacked lithium battery core structure, including two limiting plates 1. A fixing plate is fixedly connected to the opposite side of each limiting plate 1 near its bottom. A fixing hole is provided in the middle of the top side of each fixing plate, facilitating equipment installation. A sliding groove 2 is provided in the middle of the opposite side of each limiting plate 1, with two arc-shaped sliding holes 3 arranged far apart from each other. A cutting assembly 4 is provided on each limiting plate 1, enabling double-sided cutting of the lithium battery core, thereby increasing cutting efficiency. The cutting assembly 4 includes two sliding plates 41, both sides of which slide within the sliding groove 2 on the opposite side of each limiting plate 1. The sliding groove 2 on the opposite side of each limiting plate 1 guides the two sliding plates 41, preventing them from shifting during movement. A cutting blade 42 is fixedly installed on the opposite side of each sliding plate 41. The cutting blades 42 are staggered. When the two cutting blades 42 move towards each other, they cut the lithium battery core, thereby cutting the lithium battery core on both sides and increasing the cutting efficiency. A first rotating column 43 is slidably connected in the arc-shaped sliding hole 3, and one end of the first rotating column 43 is fixedly connected to one side of the sliding plate 41. The arc-shaped sliding hole 3 can limit the first rotating column 43. A second rotating column 44 is fixedly connected to the middle position of the opposite side of the two limiting plates 1. A first rotating bar 45 is rotatably connected to the outside of the second rotating column 44, and the second rotating column 44 is located at the center position of the first rotating bar 45. The second rotating column 44 can ensure that the first rotating bar 45 rotates in the middle position of one side of the limiting plate 1. A third rotating column 46 is fixedly connected to one side of the first rotating bar 45 near both ends. A second rotating bar 47 is rotatably connected to the outside of the third rotating column 46. The two second rotating bars 47 can drive another sliding plate 41 to slide between the two limiting plates 1.

[0021] Please see Figures 1-3As shown, a receiving plate 5 is fixedly connected to the top side of the two limiting plates 1. A driving cylinder 6 is fixedly installed at the center of the top side of the receiving plate 5. The piston rod end of the driving cylinder 6 is fixedly connected to the top side of one of the sliding plates 41. When the driving cylinder 6 drives one of the sliding plates 41 to slide between the two limiting plates 1, the two first rotating columns 43 drive the two second rotating bars 47 to squeeze one of the third rotating columns 46, causing the first rotating bar 45 to rotate outside the second rotating column 44. At the same time, the other third rotating column 46 squeezes the other second rotating bar 47. The other second rotating bar 47 drives the other sliding plate 41 to slide between the two limiting plates 1 through one of the first rotating columns 43. At the same time, both sliding plates 41 slide along the sliding groove 2 on the opposite side of the limiting plate 1, and the first rotating column 43 slides along the arc-shaped sliding hole 3.

[0022] In practical use, the stacked lithium battery core structure manufacturing equipment of this embodiment first places the lithium battery core between two cutting blades 42. When the driving cylinder 6 drives one of the sliding plates 41 to slide between two limiting plates 1, the two first rotating columns 43 drive the second rotating strip 47 to squeeze one of the third rotating columns 46, causing the first rotating strip 45 to rotate outside the second rotating column 44. At the same time, the other third rotating column 46 squeezes the other second rotating strip 47. When the other second rotating strip 47 drives the other sliding plate 41 to slide between the two limiting plates 1 through one of the first rotating columns 43, and when the two sliding plates 41 drive the two cutting blades 42 to move towards each other, the lithium battery core is cut, thereby performing double-sided cutting of the lithium battery core and increasing cutting efficiency.
