Description

Technical Field

[0001] The present invention belongs to the technical field of solid-state battery processing, and in particular relates to a solid-state battery cutting and stacking machine. 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] In the production process of rectangular power lithium batteries, pole piece cutting and pole piece lamination are two very important production processes, and corresponding cutting and lamination equipment are required to complete the processing process. Conventional pole piece cutting machines and lithium battery lamination machines are usually separate machines. The cut pole pieces need to be transported to the lamination machine by manual handling or assembly line transportation for lamination. During the transportation process, it is easy to cause damage to the edge of the pole piece, and there are problems such as low automation, low production efficiency, high labor cost, and high labor intensity. In addition, in conventional pole piece cutting machines, the pole piece belt is clamped and rolled by a pressure roller and a traction roller, and the pole piece belt is conveyed to a cutting mold, and then the pole piece belt is cut into the required size by the cutting mold for subsequent lamination. However, since the surface of the solid-state battery pole piece is coated with a layer of gelatinous material, the gelatinous material has a certain viscosity. When the pole piece belt is rolled by a pressure roller and a traction roller, the pole piece belt is easy to stick to the traction roller, resulting in the inability to smoothly feed the material, affecting production. Summary of the invention

[0005] The purpose of the present invention is to provide a solid-state battery cutting and stacking machine, aiming to solve one of the technical problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides a solid-state battery cutting and stacking machine, comprising a frame, and a two-pole strip unwinding device, a two-pole ear die-cutting device, a two-pole strip pushing and cutting device, and a stacking device which are sequentially arranged on the frame;

[0007] The two-electrode sheet unwinding device is used to unwind the positive electrode sheet and the negative electrode sheet respectively;

[0008] The two tab die-cutting devices are used to die-cut the positive electrode strip and the negative electrode strip respectively, so that tabs are formed on both the positive electrode strip and the negative electrode strip;

[0009] The two-electrode sheet pushing and cutting device is used to respectively convey and cut the positive electrode sheet and the negative electrode sheet to form positive electrode sheets and negative electrode sheets;

[0010] The laminating device comprises two pole piece splicing mechanisms, two positioning mechanisms, two laminating mechanisms and a stacking mechanism; the two pole piece splicing mechanisms are respectively arranged on the sides of the two pole piece belt pushing and cutting devices, and the sides of each pole piece splicing mechanism are provided with a positioning mechanism and a laminating mechanism, and a stacking mechanism is arranged between the two laminating mechanisms;

[0011] The two electrode sheet connecting mechanisms are used to respectively receive the positive electrode sheet and the negative electrode sheet; the two stacking mechanisms are used to respectively absorb the positive electrode sheet and the negative electrode sheet on the two electrode sheet connecting mechanisms and transfer them to the two positioning mechanisms respectively, so that the two positioning mechanisms are used to respectively position the positive electrode sheet and the negative electrode sheet, and then transfer the positioned positive electrode sheet and negative electrode sheet to the stacking mechanism for stacking, so that the positive electrode sheet and the negative electrode sheet are stacked together layer by layer in sequence to form a battery cell.

[0012] Compared with the prior art, the above one or more technical solutions in the solid-state battery cutting and stacking machine provided in the embodiment of the present invention have at least one of the following technical effects:

[0013] During operation, the two electrode tape unwinding devices unwind the positive electrode tape and the negative electrode tape respectively, so that the electrode tapes pass through the pole ear die-cutting device and the electrode tape pushing and cutting device in sequence; the two pole ear die-cutting devices die-cut the positive electrode tape and the negative electrode tape respectively, so that pole ears are formed on both the positive electrode tape and the negative electrode tape; the two pole tape pushing and cutting devices respectively transport and cut the positive electrode tape and the negative electrode tape to form positive and negative electrode sheets; the two pole sheet splicing mechanisms respectively receive the positive and negative electrode sheets, and the two laminating mechanisms respectively absorb the two pole sheet splicing mechanisms The positive and negative electrode sheets on the battery are respectively transferred to the two positioning mechanisms, so that the two positioning mechanisms position the positive and negative electrode sheets respectively, and the two stacking mechanisms then transfer the positioned positive and negative electrode sheets to the stacking mechanism for stacking, so that the positive and negative electrode sheets are stacked together layer by layer in sequence to form a battery cell. There is no need to transport the cut electrode sheets to the stacking machine for stacking by manual handling or assembly line transportation, etc., which has the advantages of high degree of automation, high production efficiency, low labor cost and high stacking accuracy.

[0014] In addition, the first driving component drives the two first clamps to approach each other to clamp the electrode band in the first clamping position, and then the pushing component drives the two first clamps and the electrode band to move in the direction close to the die-cutting mechanism (forward), thereby conveying (pushing) the electrode band to the die-cutting mechanism; then the first driving component drives the two first clamps away from each other to release the electrode band, and drives the two first clamp bands to move in the direction away from the die-cutting mechanism (backward) to reset through the pushing component, and repeats the above actions, so that the electrode band is continuously conveyed to the die-cutting mechanism, which is beneficial to production.

[0039] Compared with the prior art, the above one or more technical solutions in the solid-state battery cutting and stacking machine provided in the embodiment of the present invention have at least one of the following technical effects:

[0040] Reference Figure 1 and Figure 2 When working, the two electrode tape unwinding devices 200 unwind the positive electrode tape 10 and the negative electrode tape 10 respectively, so that the electrode tape 10 passes through the tab die-cutting device 300 and the electrode tape pushing and cutting device 400 in sequence; the two tab die-cutting devices 300 respectively die-cut the positive electrode tape 10 and the negative electrode tape 10, so that the positive electrode tape 10 and the negative electrode tape 10 are both formed with tabs; the two electrode tape pushing and cutting devices 400 respectively transport and cut the positive electrode tape 10 and the negative electrode tape 10 to form positive and negative electrode sheets; the two electrode sheet connecting mechanisms 510 respectively receive the positive and negative electrode sheets, and the two laminating mechanisms 55 0 respectively absorbs the positive electrode sheet and the negative electrode sheet on the two electrode sheet connecting mechanisms 510 and transfers them to the two positioning mechanisms 530 respectively, so that the two positioning mechanisms 530 respectively position the positive electrode sheet and the negative electrode sheet, and the two stacking mechanisms 550 then transfer the positioned positive electrode sheet and the negative electrode sheet to the stacking mechanism 570 for stacking, so that the positive electrode sheet and the negative electrode sheet are stacked together layer by layer in sequence to form a battery cell 20, without the need to transport the cut electrode sheets to the stacking machine for stacking by manual handling or assembly line transportation, etc., which has the advantages of high degree of automation, high production efficiency, low labor cost, and high stacking accuracy.

[0041] In another embodiment of the present invention, referring to Figure 2The electrode tape unwinding device 200 includes a first vertical plate 210, an unwinding roller 220, a guide roller 230 and a first driving assembly 240. The first vertical plate 210 is arranged on the frame 100, and the unwinding roller 220 is rotatably arranged on the first vertical plate 210. The unwinding roller 220 is used to place the rolled electrode tape 10. The first driving assembly 240 is arranged on the first vertical plate 210, and the first driving assembly 240 is connected to the unwinding roller 220 and is used to drive the unwinding roller 220 to rotate. The circumferential surfaces of the plurality of guide rollers 230 are provided with an anti-stick coating, and the plurality of guide rollers 230 are rotatably arranged on the first vertical plate 210 and are used to guide the electrode tape 10. By providing an anti-stick coating on the circumferential surface of the guide roller 230, the electrode tape 10 is not easy to stick to the guide roller 230, so that the electrode tape 10 can be smoothly fed, which is beneficial to production. The electrode tape 10 on the unwinding roller 220 sequentially passes through a plurality of guide rollers 230, a tab die-cutting device 300, and an electrode tape pushing and cutting device 400. Specifically, the first driving assembly 240 may be a first motor, the shaft of which is transmission-connected to one end of the unwinding roller 220, and the unwinding roller 220 is driven to rotate by the first motor to unwind the electrode tape 10 (positive electrode tape 10 or negative electrode tape 10).

[0042] Further, refer to Figure 2 The first vertical plate 210 is also provided with a winding roller 250 for rotation. The first vertical plate 210 is also provided with a third driving component (not shown) for driving the winding roller 250 to rotate. The winding roller 250 collects the protective film torn off the pole piece belt 10 by rotating. Specifically, the third driving component can be a third motor, and the rotating shaft of the third motor is drivingly connected to one end of the winding roller 250.

[0043] In another embodiment of the present invention, referring to Figure 2 The pole tab die-cutting device 300 includes a first bracket 310, a second drive assembly 320, an upper die 330 and a lower die 340. The first bracket 310 is arranged on the frame 100, and the second drive assembly 320 is arranged on the first bracket 310. The upper die 330 and the lower die 340 are arranged opposite to each other up and down and are respectively arranged on the second drive assembly 320 and the first bracket 310. The pole piece strip 10 passes between the upper die 330 and the lower die 340. The second drive assembly 320 is used to drive the upper die 330 and the lower die 340 to close or open the mold, and die-cut the pole piece strip 10 when closing the mold, so that the pole tab and V angle are formed on the pole piece strip 10. Specifically, the second drive assembly 320 is a straight rod cylinder, and the drive rod of the straight rod cylinder movably passes through the first bracket 310 and is fixedly connected to the upper die 330. Through the telescopic movement of the drive rod of the straight rod cylinder, the upper die 330 and the lower die 340 are driven to reciprocate to close or open the mold. In addition, the upper mold 330 is driven to move up and down by a straight rod cylinder, and the mold opening stroke is large, which is convenient for subsequent workers to clean the upper mold 330 and the lower mold 340.

[0044] In another embodiment of the present invention, referring to Figure 1 and Figure 3 The pole piece tape pushing and cutting device 400 comprises a base 410 , and a pole piece tape pushing mechanism 420 and a die cutting mechanism 450 which are sequentially arranged on the base 410 . The base 410 is arranged on the frame 100 .

[0045] Among them, refer to Figure 3 and Figure 5 The pole piece belt pushing mechanism 420 includes a pushing assembly 430, a first stand 421, a first driving component 422 and two first clamping plates 423. The pushing assembly 430 is arranged on the base 410, the first stand 421 is arranged on the pushing assembly 430, the two first clamping plates 423 are arranged opposite to each other up and down and form a first clamping position 424 therebetween, and the end surfaces of the two first clamping plates 423 that are close to each other are both first clamping surfaces 423a, and both first clamping surfaces 423a are provided with anti-stick coatings. The first driving component 422 is arranged on the first stand 421 and is used to drive the two first clamping plates 423 to move closer to or away from each other, thereby clamping or releasing the pole piece belt 10 located in the first clamping position 424.

[0046] Among them, refer to Figure 3 and Figure 5 The pushing assembly 430 is used to drive the two first clamping plates 423 to move back and forth, so that the two first clamping plates 423 continuously transport the pole piece tape 10 located in the first clamping position 424 to the die-cutting mechanism 450, and the die-cutting mechanism 450 is used to cut the pole piece tape 10.

[0047] Reference Figure 3 and Figure 5 During operation, the first driving component 422 drives the two first clamping plates 423 to approach each other to clamp the electrode strip 10 located in the first clamping position 424, and then the pushing component 430 drives the two first clamping plates 423 and the electrode strip 10 to move (forward) in the direction close to the die-cutting mechanism 450, thereby conveying (pushing) the electrode strip 10 to the die-cutting mechanism 450; then the first driving component 422 drives the two first clamping plates 423 away from each other to release the electrode strip 10, and drives the two first clamping plates 423 to move (backward) in the direction away from the die-cutting mechanism 450 to reset through the pushing component 430, and repeats the above actions, so that the electrode strip 10 is continuously conveyed to the die-cutting mechanism 450, which is beneficial to production.

[0048] Reference Figure 3 and Figure 5Since the two first clamping surfaces 423a are both provided with an anti-stick coating, the electrode tape 10 is clamped by the two first clamping plates 423, and the electrode tape 10 is not easy to stick to the first clamping surface 423a of the first clamping plate 423, so that the electrode tape 10 can be fed smoothly. Compared with the existing method of clamping and rolling the electrode tape 10 by the pressure roller and the traction roller, the electrode tape 10 is always in contact with the pressure roller and the traction roller, which makes it easy to stick to the roller. In the present application, the electrode tape 10 is clamped by the two first clamping plates 423 and pushed. Only the clamped part of the electrode tape 10 is in contact with the first clamping plate 423, and the unclamped part of the electrode tape 10 does not contact the first clamping plate 423 and is transported forward by pushing. Therefore, it is not easy for the electrode tape 10 to stick to the first clamping plate 423, so that the electrode tape 10 can be fed smoothly, which is beneficial to production.

[0049] Further, refer to Figure 3 and Figure 5 , the two first clamping surfaces 423a are each provided with a plurality of first blowing holes 423b, and the first blowing holes 423b are used to blow air to separate the pole piece belt 10 from the two first clamping surfaces 423a. Specifically, the first clamping plate 423 is provided with a first air joint 423c connected to the plurality of first blowing holes 423b, and the first air joint 423c is connected to a high-pressure air pump (not shown) through an air pipe, and the high-pressure air pump provides high-pressure gas to the plurality of first blowing holes 423b along the air pipe. When the two first clamping plates 423 are away from each other, the plurality of first blowing holes 423b blow air to separate the pole piece belt 10 from the first clamping surface 423a, so that the pushing assembly 430 drives the two first clamping plates 423 to move (move backward) in a direction away from the die-cutting mechanism 450, and the reset will not drive the pole piece belt 10 to move backward.

[0050] In another embodiment of the present invention, referring to Figure 3 and Figure 5 The first driving component 422 includes two first cylinders both provided on the first stand 421. The driving rods of the two first cylinders are respectively fixedly connected to the two first clamping plates 423 for driving the two first clamping plates 423 to move closer to or farther from each other. Specifically, the two first clamping plates 423 are driven to move closer to or farther from each other through the telescopic movement of the driving rods of the two first cylinders, and the structure is simple.

[0051] Further, refer to Figure 3 and Figure 5 The two first clamping plates 423 are each connected to at least one first guide rod 425, the axis of the first guide rod 425 is parallel to the moving direction of the first clamping plates 423, and each first guide rod 425 is slidably connected to the first stand 421 through a first guide sleeve 426. The first guide rod 425 cooperates with the first guide sleeve 426 to play a guiding role, so that the two first clamping plates 423 can move up and down stably, and the structure is stable.

[0052] In another embodiment of the present invention, referring to Figure 3 and Figure 5 The pushing assembly 430 includes a pushing linear module 431 and a linear guide 432 disposed on the base 410. The first stand 421 is disposed on a moving block of the pushing linear module 431 and a slider 433 of the linear guide 432, and the pushing linear module 431 is used to drive the two first clamping plates 423 to reciprocate along the linear guide 432. Specifically, the pushing linear module 431 drives the first stand 421 to reciprocate (move forward and backward) along the linear guide 432, thereby driving the two first clamping plates 423 to reciprocate (move forward and backward) along the linear guide 432. When the two first clamping plates 423 clamp the pole piece strip 10 and move forward, the pole piece strip 10 is driven to move (move forward) in a direction close to the die-cutting mechanism 450, thereby conveying (pushing) the pole piece strip 10 to the die-cutting mechanism 450.

[0053] In another embodiment of the present invention, referring to Figure 3 and Figure 6 , the electrode tape pushing and cutting device 400 also includes an electrode tape clamping mechanism 440. The electrode tape clamping mechanism 440 includes a second stand 441, a second driving component 442 and two second clamping plates 443. The second stand 441 is arranged on the base 410 and is located between the electrode tape pushing mechanism 420 and the die-cutting mechanism 450. The two second clamping plates 443 are arranged opposite to each other up and down and form a second clamping position 444 between the two. The end surfaces of the two second clamping plates 443 that are close to each other are both second clamping surfaces 443a, and the two second clamping surfaces 443a are both provided with an anti-stick coating. The second driving component 442 is arranged on the second stand 441 and is used to drive the two second clamping plates 443 to move closer to or away from each other, thereby clamping or releasing the electrode tape 10 located in the second clamping position 444. When the two second clamping plates 443 clamp the electrode tape 10, the two first clamping plates 423 release and detach from the electrode tape 10 and move to reset under the drive of the pushing assembly 430.

[0054] Specifically, refer to Figure 3 and Figure 6 The pole piece belt 10 is clamped by the two second clamping plates 443. At this time, the two first clamping plates 423 are away from each other and the blowing of the first blowing hole 423b can make the first clamping plates 423 and the pole piece belt 10 easily detached, and the pushing component 430 will not drive the pole piece belt 10 to move backward when driving the two first clamping plates 423 to move backward and reset, and the structure is reliable.

[0055] Further, refer to Figure 3 and Figure 6, the two second clamping surfaces 443a are each provided with a plurality of second blowing holes 443b, and the second blowing holes 443b are used to blow air to separate the pole piece belt 10 from the two second clamping surfaces 443a. Specifically, the connection method between the second blowing holes 443b and the high-pressure air pump is consistent with the connection method between the first blowing holes 423b and the high-pressure air pump. When the two second clamping plates 443 move away from each other, the plurality of second blowing holes 443b blow air to separate the pole piece belt 10 from the second clamping surfaces 443a.

[0056] In another embodiment of the present invention, referring to Figure 3 and Figure 6 , the second clamping plate 443 located at the bottom is fixedly arranged on the second stand 441. The second driving component 442 includes a second cylinder arranged on the second stand 441. The driving rod of the second cylinder is fixedly connected to the second clamping plate 443 located at the top, and is used to drive one of the second clamping plates 443 to approach or move away from the other second clamping plate 443, so that the two second clamping plates 443 are moved closer to or away from each other. Specifically, through the telescopic movement of the driving rod of the second cylinder, the one of the second clamping plates 443 is driven to approach or move away from the other second clamping plate 443, so that the two second clamping plates 443 are moved closer to or away from each other, and the structure is simple.

[0057] Further, refer to Figure 3 and Figure 6 The second clamping plate 443 at the top is connected with at least one second guide rod 446, the axis of the second guide rod 446 is parallel to the moving direction of the second clamping plate 443 at the top, and each second guide rod 446 is slidably connected to the second stand 441 through a second guide sleeve 447. The second guide rod 446 cooperates with the second guide sleeve 447 to play a guiding role, so that the second clamping plate 443 at the top can move up and down stably, and the structure is stable.

[0058] In another embodiment of the present invention, referring to Figure 3 and Figure 4 The die-cutting mechanism 450 includes a third stand 451, a third driving member 452, a movable knife 453 and a fixed knife seat 454. The movable knife 453 and the fixed knife seat 454 are arranged opposite to each other up and down and a cutting position 455 is formed therebetween. The third driving member 452 is arranged on the third stand 451 and is used to drive the movable knife 453 to move back and forth, and cut the pole piece strip 10 located in the cutting position 455 when the movable knife 453 cooperates with the fixed knife seat 454. Specifically, the third driving member 452 drives the movable knife 453 to move downward toward the fixed knife, and the movable knife 453 cooperates with the fixed knife seat 454 to cut the pole piece strip 10 located in the cutting position 455, thereby obtaining a pole piece of the required size for subsequent lamination. Specifically, the third driving member 452 includes a third cylinder; the movable knife 453 is driven up and down by the driving rod of the third cylinder.

[0059] Further, refer to Figure 3 and Figure 4 , the movable knife 453 is arranged on the third driving member 452 through an upper mounting seat 456, and a protective seat 457 is arranged on the upper mounting seat 456, and the protective seat 457 is provided with a socket 457a. The die-cutting mechanism 450 includes a latch protection mechanism 460. The latch protection mechanism 460 includes a latch 461 and a driving member 462. The driving member 462 is arranged on the first stand 421, and the driving member 462 is connected to the latch 461 and is used to drive the latch 461 to insert into the socket 457a or leave the socket 457a. Specifically, the driving member 462 drives the latch 461 to insert into the socket 457a, locks the third driving member 452, and thus locks the movable knife 453 on the upper mounting seat 456. At this time, the movable knife 453 cannot move downward even under the drive of the third driving member 452, so that the user can clean the die-cutting mechanism 450, which is highly safe. The driving member 462 drives the latch 461 to leave the insertion hole 457 a, unlocking the third driving member 452 , thereby unlocking the movable knife 453 on the upper mounting seat 456 . The movable knife 453 continues to cut the pole piece strip 10 under the drive of the third driving member 452 .

The receiving platform 511 is arranged beside the electrode sheet belt pushing and cutting device 400 and is used to receive the positive electrode sheet or the negative electrode sheet. The first X-direction transfer assembly 513 is arranged on the frame 100. The third driving component 514 is arranged on the first X-direction transfer assembly 513 through a splicing seat 515. The two splicing plates 512 are arranged opposite to each other and are respectively arranged on the third driving component 514 and the splicing seat 515. The end surfaces of the two splicing plates 512 that are close to each other are both third clamping surfaces, and both third clamping surfaces are provided with anti-sticking coatings.

Specifically, the first X-axis transfer component 513 drives the two splice plates 512 to move forward (move in the direction close to the fixed knife seat 454) and clamp the end of the electrode belt 10 through the two splice plates 512, and then the electrode belt 10 is transported under the drive of the electrode belt pushing mechanism 420.

Then the two splice plates 512 release the positive electrode sheet or negative electrode sheet and continue to retreat under the drive of the first X-axis transfer component 513, so that the positive electrode sheet or negative electrode sheet is placed (falls on) the receiving platform 511.

[0062] Specifically, the first X-direction transfer assembly 513 can be a linear module, which drives the two splice plates 512 to reciprocate along the X-direction, and has a simple structure. The third driving component 514 can be a cylinder, which drives one splice plate 512 to move closer to or away from the other splice plate 512.

[0063] In another embodiment of the present invention, referring to Figure 1 , Figure 7 and Fig.13The stacking mechanism 550 includes a manipulator 551 and a suction plate 552. The manipulator 551 is disposed on the frame 100, and the suction plate 552 is disposed on the manipulator 551. The bottom surface of the suction plate 552 is an adsorption surface, and the adsorption surface is provided with an anti-stick coating, and the adsorption surface is provided with a plurality of first air holes (not shown in the figure). The suction plate 552 absorbs or releases the positive electrode sheet or the negative electrode sheet through the plurality of first air holes. The manipulator 551 is used to drive the suction plate 552 to move between the electrode sheet connecting mechanism 510, the positioning mechanism 530 and the stacking mechanism 570. Specifically, the first air hole adsorbs the positive electrode sheet or the negative electrode sheet on the receiving platform 511 onto the adsorption surface through negative pressure, and then the robot 551 drives the suction plate 552 to move, firstly the positive electrode sheet or the negative electrode sheet is positioned by the positioning mechanism 530, and then the positive electrode sheet or the negative electrode sheet is transferred to the stacking mechanism 570, and the first air hole cancels the adsorption of the positive electrode sheet or the negative electrode sheet through positive pressure, so that the positive electrode sheet or the negative electrode sheet is stacked on the stacking mechanism 570. Among them, the robot 551 is a mature existing technology and will not be described in detail here.

[0064] Specifically, the suction plate 552 is provided with a second gas joint 553 connected to a plurality of first gas holes, and the second gas joint 553 is connected to an air pump (not shown) through an air pipe, and the air pump provides low-pressure gas (negative pressure gas) or high-pressure gas (positive pressure gas) along the air pipe to the plurality of second gas joints 553. The anti-stick coating is a Teflon coating, a ceramic coating, or a nano coating, etc., which is not limited here.

[0065] In another embodiment of the present invention, referring to Figure 1 , Figure 7 and Fig. 9 The positioning mechanism 530 includes a positioning bracket 531, a positioning platform 532 and a plurality of CCD cameras 533. The positioning bracket 531 and the positioning platform 532 are both disposed on the frame 100, and the plurality of CCD cameras 533 are both disposed on the positioning bracket 531 and located directly above the positioning platform 532. The stacking mechanism 550 suspends the positive electrode sheet or the negative electrode sheet between the positioning platform 532 and the multiple CCD cameras 533, so that the multiple CCD cameras 533 take pictures and position the positive electrode sheet or the negative electrode sheet, and then the mechanical arm 551 of the stacking mechanism 550 drives the suction plate 552 to rotate to adjust (correct) the position of the positive electrode sheet or the negative electrode sheet adsorbed thereon, and after correction, directly puts the electrode sheet on the stacking platform 571 of the stacking mechanism 570 for stacking. In this way, the electrode sheet does not need to contact the positioning platform 532, and the action of placing the electrode sheet on the positioning platform 532 for positioning and then sucking the electrode sheet to the stacking platform 571 for stacking is omitted. Because the solid-state battery electrode sheet has a gel layer, it is prevented that the electrode sheet is placed on the positioning platform 532 to increase the risk of electrode sheet damage and suction failure, and the structure is reliable. Among them, the CCD camera 533 is a mature existing technology.

[0066] In another embodiment of the present invention, referring to Figure 1, Figure 7 and Fig.10 The stacking mechanism 570 includes a stacking platform 571, a plurality of pressing plates 572, a plurality of first Y-direction transfer assemblies 573, and a plurality of first Z-direction transfer assemblies 574. The stacking platform 571 is arranged on the frame 100, the plurality of first Y-direction transfer assemblies 573 are arranged beside the stacking platform 571, the plurality of first Z-direction transfer assemblies 574 are respectively arranged on the plurality of first Y-direction transfer assemblies 573, and the plurality of pressing plates 572 are respectively arranged on the plurality of first Z-direction transfer assemblies 574 and are located above the stacking platform 571. The suction plates 552 of the two stacking mechanisms 550 are used to transfer the positioned positive and negative electrode sheets to the stacking platform 571 for stacking, and the first Y-direction transfer assemblies 573 and the first Z-direction transfer assemblies 574 are used to drive the pressing plates 572 to approach or move away from the positive electrode sheet or the negative electrode sheet on the stacking platform 571, thereby pressing or releasing the positive electrode sheet or the negative electrode sheet. For example, one stacking mechanism 550 stacks the positive electrode sheet on the stacking platform 571, and the first Y-direction transfer assembly 573 and the first Z-direction transfer assembly 574 located on one side of the stacking platform 571 drive the corresponding pressing sheet 572 to approach and press one end of the positive electrode sheet, and then the other stacking mechanism 550 stacks the negative electrode sheet on the positive electrode sheet, and the first Y-direction transfer assembly 573 and the first Z-direction transfer assembly 574 located on the other side of the stacking platform 571 drive the corresponding pressing sheet 572 to approach and press one end of the negative electrode sheet, and repeat the above steps to stack the positive electrode sheet and the negative electrode sheet layer by layer to form a battery cell 20. Since the surfaces of the new solid-state battery positive electrode sheet and the new solid-state battery negative electrode sheet are coated with a layer of gelatinous material, the gelatinous material adheres the solid-state battery positive electrode sheet to the solid-state battery negative electrode sheet and separates the solid-state battery positive electrode sheet and the solid-state battery negative electrode sheet, it is necessary to use a diaphragm in the prior art to separate the positive electrode sheet and the negative electrode sheet, which greatly improves the stacking efficiency and reduces the production cost.

[0067] Specifically, the first Y-axis transfer component 573 and the first Z-axis transfer component 574 can both be driving structures such as linear modules or cylinders, which drive the pressing plate 572 to move closer to or away from the positive electrode sheet or the negative electrode sheet on the stacking table 571, thereby compressing or releasing the positive electrode sheet or the negative electrode sheet.

The spacer support plate 593 is arranged in the spacer slot 592, and the spacer is adapted to be stacked on the spacer support plate 593 and is located in the spacer slot 592. The lifting drive assembly 594 is arranged on the frame 100, and the lifting drive assembly 594 is transmission-connected with the spacer support plate 593 and is used to drive the spacer support plate 593 to move up to output the spacer. The stacking mechanism 550 is used to absorb the spacer and transplant it into the stacking mechanism 570, so that the spacer is placed on the bottom and top layers of the battery cell 20. Specifically, before the first positive electrode sheet or negative electrode sheet is stacked on the stacking platform 571 of the stacking mechanism 570, a spacer in the spacer groove 592 is sucked out from the discharge port by the stacking mechanism 550 and placed on the stacking platform 571, and then the positive electrode sheet and the negative electrode sheet are stacked together layer by layer on the spacer to form a battery cell 20; after the battery cell 20 is formed, a spacer in the spacer groove 592 is sucked out from the discharge port by the stacking mechanism 550 and stacked on the top layer of the battery cell 20, so that the two spacers are respectively located at the bottom and top layers of the battery cell 20, and the two spacers play a role in protecting the battery cell 20, and are not easily worn during the transportation or transfer of the battery cell 20.

[0069] Specifically, the lifting drive assembly 594 can be a linear module, which drives the spacer support plate 593 through the linear module to move the stacked spacers in the spacer groove 592 upward. That is, after the spacer at the top in the spacer groove 592 is taken away, the lifting drive assembly 594 drives the spacer support plate 593 to move the spacer in the spacer groove 592 upward to fill its position.
