Description

Technical Field

[0001] The present invention relates to the technical field of solid-state battery assembly, and in particular to an all-solid-state battery core stacking device. Background Art

[0002] With the development of lithium battery technology and the application of new materials, lithium batteries have become the mainstream, and the characteristics of new lithium battery pole pieces have also changed greatly. Among them, power lithium batteries usually have two appearances: cylindrical power lithium batteries and rectangular power lithium batteries. The cylindrical power lithium battery adopts a spiral winding structure inside, while the rectangular power lithium battery forms a battery cell by stacking sheets.

[0003] For the new solid-state battery electrode, a layer of gelatinous material is coated on the surface of the new solid-state battery electrode. The gelatinous material adheres the solid-state battery positive electrode to the solid-state battery negative electrode and separates the solid-state battery positive electrode from the solid-state battery negative electrode when stacking.

[0004] When working, the existing stacking machine uses a suction cup to absorb the positive and negative electrode sheets of the battery cells located in the two material frames and move them to the stacking station in sequence for stacking. The process is fully automated. After stacking on the battery cell placement station, it is necessary to press the pressing sheet on the battery cell to prevent the battery cell from moving and to prevent the diaphragm on the lower side of the pressing sheet from being over-tightened. The pressing sheet is pressed on the battery cell by a longitudinal cylinder. When a new battery cell is put down, the longitudinal cylinder is pulled to move horizontally by a transverse cylinder so that the pressing sheet leaves the battery cell. Then, the longitudinal cylinder raises the pressing sheet and moves it to the upper side of the new battery cell through the transverse cylinder. The longitudinal cylinder moves the pressing sheet down and presses it on the new battery cell. The above steps are repeated. As more battery cells are stacked, the force of the pressing sheet on the battery cell increases. The increased pressure may cause damage to the internal structure of the battery cell, such as the shedding of active substances and deformation of the electrode sheets, thereby affecting the performance and life of the battery. Summary of the invention

The transmission rod 334 rotates to rotate the adjusting plate 335, and the adjusting plate 335 rotates the fixing rod 336, thereby rotating the adjusting wheel 332. When the last battery cell is placed, all the pressing sheets 2 leave. In the process of leaving, the adjusting plate 335 moves axially through the inclined surface of the protrusion 338, thereby separating from the fixing rod 336. Under the action of the spring 1 35, the connecting member 32, the adjusting wheel 332 and the pressing sheet 2 return to their original positions.

The synchronization bar 81 causes the transmission rod 334 and the synchronization rod 8 to rotate together, and the transmission rod 334 moves axially on the synchronization rod 8.

[0037] A driving component 36 with a transmission rod 334 that rotates unidirectionally is provided between the synchronization rod 8 and the slide seat 4. The driving component 36 includes a ratchet 362 and a ratchet 361 fixed on the synchronization rod 8. The ratchet 362 is connected to the support frame 331 through a torsion spring 3621.

[0038] The driving component 36 also includes a driving rod 363, which is rotatably connected to the support frame 331. The driving rod 363 is longitudinally arranged. The upper end of the driving rod 363 is connected to the synchronization rod 8 through a bevel gear pair 364. A driving gear 365 is fixed to the lower end of the driving rod 363. The driving rod 363 includes an upper rod body 3631 and a lower rod body 3632. The upper rod body 3631 is rotatably connected to the support frame 331. The lower rod body 3632 has a convex plate. The upper end of the lower rod body 3632 is inserted into the upper rod body 3631. The upper rod body 3631 is slidably connected to the lower rod body 3632. The convex plate makes the upper rod body 3631 and the lower rod body 3632 rotates synchronously, the slide seat 4 is fixed with a fixed plate 366, the fixed plate 366 is provided with a lifting tooth plate 367, the driving rod 363 is sleeved with a limit block 3633, the limit block 3633 is slidably connected to the fixed plate 366, the limit block 3633 is fixedly connected with a guide rod 3634, the upper side of the tooth plate 367 is provided with a guide groove 3671, both ends of the guide groove 3671 are provided with guide inclined surfaces 3672, the fixed plate 366 is fixed with a vertical rod, the vertical rod passes through the tooth plate 367, the vertical rod is sleeved with a spring four 368, and the two ends of the spring four 368 are respectively connected to the tooth plate 367 and the fixed plate 366.

[0039] When in use, after the battery cell is placed, taking the two pressing sheets 2 on the left as an example, the transverse cylinder 5 moves the movable frame 6, and the movable frame 6 moves with the supporting frame 331, and the supporting frame 331 moves the driving rod 363, and the driving rod 363 moves the limit block 3633 and the guide rod 3634, and the guide rod 3634 contacts the guide inclined surface 3672 of the tooth plate 367, and the guide rod 3634 causes the tooth plate 367 to rise through the guide inclined surface 3672, and the upper side of the tooth plate 367 contacts the fixed plate 366, and the fixed plate 366 limits the tooth plate 367, and the teeth on the tooth plate 367 are at the same height as the driving gear 365, and the spring four 368 is stretched. After the tooth plate 367 rises, the guide rod 3634 enters the transverse section of the guide groove 3671, and then the tooth plate 367 causes the driving gear 365 to rotate, and the driving gear 365 causes the driving rod 363 to rotate, and the driving rod 363 causes the synchronous The rod 8 rotates, and the synchronization rod 8, the ratchet 361 and the synchronization bar 81 rotate together. The synchronization bar 81 causes the transmission rod 334 to rotate, and the transmission rod 334 rotates with the adjustment plate 335. The adjustment plate 335 causes the fixing rod 336 to rotate, and then the adjusting wheel 332 rotates. The rotation of the adjusting wheel 332 causes the lower end of the connecting belt 333 to rise, and the connecting belt 333 causes the plate body 2 322 to rise. The spring 1 35 pulls up, and the plate body 2 322 causes the plate body 1 321 to rise through the rod body 1 324, the rod body 2 323 and the spring 325. The plate body 1 321 rises with the pressing piece 2. When the driving gear 365 separates from the teeth on the tooth plate 367, the pressing piece 2 stops rising. At this time, the ratchet 362 locks the ratchet 361 through the torsion spring 3621 to prevent the synchronization rod 8 from rotating, so that the plate body 2 322 is stable, and then the pressing piece 2 continues to move away from the battery cell until the guide rod 3634 leaves the guide groove 3671.

[0040] Then the longitudinal cylinder 7 moves the lifting plate 31 upward, the lifting plate 31 makes the support frame 331 rise, the support frame 331 makes the upper rod 3631 rise, the lifting plate 31 makes the adjusting wheel 332 and the pressing plate 2 (all the parts on the upper side of the lower rod 3632) rise through the support frame 331, after moving upward, the transverse cylinder 5 makes the pressing plate 2 move toward the battery core, then the guide rod 3634 presses against the guide inclined surface 3672, so that the tooth plate 367 descends, when the guide rod 3634 separates from the tooth plate 367, the tooth plate 367 recovers under the action of the spring four 368. When the pressing plate 2 battery core moves to the upper side, the longitudinal cylinder 7 makes the lifting plate 31 descend, and the lifting plate 31 returns to its original position. During the descent of the lifting plate 31, the pressing plate 2 presses on the battery core, and the spring three 325 keeps the connecting belt 333 in a taut state. Each time a battery cell is placed, the pressing sheet 2 rises a little to correspond to the increased thickness of the battery cell and the diaphragm to prevent damage to the battery cell. After the last battery cell is placed, the adjustment plate 335 approaches the protrusion 338, and then all the pressing sheets 2 leave. During the leaving process, the adjustment plate 335 moves axially through the inclined surface and then separates from the fixing rod 336. Under the action of the spring 35, the connecting piece 32, the adjustment wheel 332 and the pressing sheet 2 return to their original positions.
