Description

Technical Field

[0001] The present invention relates to the technical field of lithium-ion batteries, and particularly to a production device for lithium-ion batteries. Background Art

[0002] The shape of the battery tab is usually a metal strip, and common materials include nickel, copper, aluminum, etc. The main function of the tab is to connect the current collector to both ends of the battery and lead out the current from the current collector. In a lithium-ion battery, the tab is usually a small metal strip.

[0003] In the patent "A Production Film Coating Device for Lithium-Ion Battery Tabs" with the application number "202410673455.3", in the process of the conveyor belt group transporting the battery tabs, under the elastic force of the spring corresponding to the slide plate, the slide plate closely adheres to the inner top surface of the conveyor belt of the conveyor belt group, so that the slide plate buffers the vibration force generated during the operation of the conveyor belt of the conveyor belt group, thus avoiding the problem that the conveyor belt group drives the battery tabs to shake, resulting in instability during film coating; at the same time, when the conveyor belt group transports the battery tabs, under the guiding action of the inclined plate, the battery tabs converge towards the middle of the conveyor belt group, and under the elastic force of the spring corresponding to the push plate, the push plate positions the battery tabs converging to the middle of the conveyor belt group. However, this solution still has the following problems:

[0004] The battery tabs move along with the conveyor belt. Although they are positioned by the spring during the movement, the spring itself has a certain elastic force, so that under the shaking force generated during the movement of the conveyor belt, the battery tabs will inevitably move at this time, thereby affecting the film coating quality. And after film coating, the coiled film area on the battery tabs at this time is definitely larger than the area of the battery tabs, and subsequent separate cutting treatment of the excess coiled film is still required.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figure 1 - Figure 9, A lithium-ion battery production device, including a base 1, and a fixing plate 2 is fixedly connected to the upper end of the base 1 through a support plate.

[0035] A commutation mechanism, the commutation mechanism includes a first groove 3 opened at the upper end of the fixing plate 2, a second groove 4 is opened at the inner bottom of the first groove 3 (as Figure 2 shown), the inner wall of the first groove 3 is fitted with a slider 5, the upper end of the slider 5 is rotatably connected to a first rod 6, the upper end of the first rod 6 is fixedly connected to a placement frame 7, the inner wall of the placement frame 7 is fixedly connected to a fixed frame 9 through an annular plate 8, a clamping mechanism is provided in the fixed frame 9, a cavity 10 is opened in the slider 5, both sides of the inner wall of the cavity 10 are elastically connected to a friction plate 12 through a plurality of return springs 11, a friction ring 13 is fixedly connected to the side wall of the first rod 6 located in the cavity 10, the inner side wall of the friction plate 12 is fitted with the outer side wall of the friction ring 13, the lower part of the side wall of the first rod 6 penetrates through the side wall of the slider 5 and is located in the second groove 4, a first gear 18 is fixedly connected to the side wall of the first rod 6 located in the second groove 4, and a toothed plate 20 is fixedly connected to the inner bottom of the second groove 4 (as Figure 6 shown), and the first gear 18 meshes with the toothed plate 20 during movement.

[0036] Two moving mechanisms are provided on the base 1, the two moving mechanisms are located on both sides of the fixing plate 2, the moving mechanism includes two conveyor wheels 31 installed on the upper end of the base 1 through two brackets, a conveyor belt 32 is connected between the two conveyor wheels 31, a plurality of push rods 33 are fixedly connected to the side wall of the conveyor belt 32, the push rods 33 are fitted with the side wall of the slider 5 during movement, and a motor 34 for driving one of the conveyor wheels 31 to rotate is installed on one of the brackets.

[0037] Further, the battery tab is in sheet form, and the battery tab is located in the fixed frame 9. At this time, the battery tab is clamped by the clamping mechanism, and then the two motors 34 are driven to rotate forward, so as to drive the two conveyor belts 32 to move from left to right through the conveyor wheels 31 (as Figure 2 shown). At this time, the two conveyor belts 32 will drive a plurality of push rods 33 to move, driving the slider 5 to slide on the inner wall of the first groove 3. At this time, the stability of the battery tab during movement can be ensured, the quality of the later film coating of the battery tab can be ensured, and it can be avoided that in the prior art, the battery tab moves with the conveyor belt. Although it is positioned by a spring during movement, the spring itself has a certain elasticity, so that under the action of the shaking force generated during the movement of the conveyor belt, the battery tab will inevitably move at this time, thereby affecting its film coating quality.

[0038] The upper end of the base 1 away from the toothed plate 20 is fixedly connected with an L-shaped plate 35, and an adsorption roller 36 is rotatably connected to the side wall of the L-shaped plate 35 through a rotating shaft.

[0039] A second gear 37 coaxial with the conveying wheel 31 is installed on one of the brackets. The side wall of the rotating shaft penetrates through the side wall of the L-shaped plate 35 and is fixedly connected with a third gear 38. The second gear 37 meshes with the third gear 38.

[0040] During the rotation of one of the conveying wheels 31, at this time, the adsorption roller 36 is driven to rotate through the second gear 37, the third gear 38 and the rotating shaft. When the battery tab moves to the adsorption roller 36, the film covering roll film on the adsorption roller 36 will adhere to the battery tab. The film covering technology is the prior art and will not be elaborated here.

[0041] After the battery tab is covered with film, when the slider 5 continues to move and the first gear 18 and the toothed plate 20 are disengaged from the initial meshing, at this time, the first gear 18 will drive the first rod 6 to rotate half a turn. Furthermore, the first rod 6 drives the placement frame 7 to rotate half a turn, rotating the battery tab located in the fixed frame 9 by half a turn to adjust the side walls of the battery tab corresponding to the two conveyor belts 32.

[0042] A cutting mechanism is provided on the base 1. The cutting mechanism includes two vertical plates 26 fixedly connected to the upper end of the base 1. The two vertical plates 26 are located on both sides of the fixed plate 2. First cylinders 27 arranged oppositely are fixedly connected to the side walls of the two vertical plates 26. The movable ends of the two first cylinders 27 are fixedly connected with first cutting knives 28. Second cylinders 29 arranged oppositely are fixedly connected to the side walls of the two vertical plates 26. The movable ends of the two second cylinders 29 are fixedly connected with second cutting knives 30.

[0043] As Figure 5 and Figure 6 shown, the two first cutting knives 28 are located on the left side of the toothed plate 20. During the movement of the film-covered battery tab on the left side of the toothed plate 20, at this time, the positions of the two first cutting knives 28 can be adjusted by adjusting the two first cylinders 27, so that the side walls of the two first cutting knives 28 close to each other are flush with the side wall of the battery tab. Furthermore, during the movement of the battery tab, the two first cutting knives 28 can cut the excess roll film on the battery tab;

[0044] The two second cutting knives 30 are located on the right side of the toothed plate 20. When the slider 5 continues to move and the first gear 18 and the toothed plate 20 are disengaged from the initial meshing, at this time, the battery tab rotates half a turn, so that the uncut part of the battery tab faces the two second cutting knives 30. Subsequently, the positions of the two second cutting knives 30 can be adjusted by adjusting the two second cylinders 29, so that the side walls of the two second cutting knives 30 close to each other are flush with the side wall of the battery tab. Furthermore, during the movement of the battery tab, the two second cutting knives 30 can cut the uncut roll film on the battery tab;

[0045] In this way, after the battery tab is covered with a film, the excess rolled film around it can be cut during the movement of the battery tab, without the need for shutdown cutting, which speeds up the production efficiency and avoids the need for subsequent separate cutting of the excess covered rolled film in the prior art.

[0046] Two chutes 14 are opened at the inner bottom of the cavity 10. The inner walls of the two chutes 14 are both slidably connected with first L-shaped rods 15. The side walls of the two first L-shaped rods 15 are respectively fixedly connected with the outer side walls of the two friction plates 12. Below the side walls of the two first L-shaped rods 15 close to each other, two first wedge-shaped plates 16 are fixedly connected. At the inner bottom of the second groove 4, two second wedge-shaped plates 17 that cooperate with the two first wedge-shaped plates 16 one by one are fixedly connected. During the movement, the two first wedge-shaped plates 16 are respectively in contact with the two second wedge-shaped plates 17.

[0047] When the two first wedge-shaped plates 16 are not in contact with the two second wedge-shaped plates 17, at this time, under the action of a plurality of return springs 11, the inner side walls of the two friction plates 12 are in close contact with the outer side wall of the friction ring 13, limiting the position of the first rod 6, and further limiting the positions of the placement frame 7 and the fixed frame 9 to ensure the stability of the position of the battery tab.

[0048] When the two first wedge-shaped plates 16 are respectively in contact with the two second wedge-shaped plates 17 during the movement, at this time, it will drive the two first wedge-shaped plates 16 to move away from each other, and then drive the two friction plates 12 to move away from each other through the two first L-shaped rods 15, releasing the first rod 6. At this time, the first gear 18 just meshes with the toothed plate 20, and then the first rod 6 can be driven to rotate.

[0049] A torsion spring 19 is sleeved on the side wall of the first rod 6 below the slider 5. The upper end of the torsion spring 19 is fixedly connected with the lower end of the slider 5, and the lower end of the torsion spring 19 is fixedly connected with the upper end of the first gear 18.

[0050] The rotation of the first rod 6 drives the rotation of the torsion spring 19, so that elastic potential energy is stored in the torsion spring 19. When the first gear 18 just separates from the toothed plate 20, at this time, the two first wedge-shaped plates 16 are respectively separated from the two second wedge-shaped plates 17, so that the inner side walls of the two friction plates 12 are in close contact with the outer side wall of the friction ring 13, limiting the position of the first rod 6. At this time, the elastic potential energy on the torsion spring 19 cannot be released. Then when the fixed frame 9 is used again later, at this time, only need to pull the two first L-shaped rods 15 outwards, so that the two friction plates 12 move away from the friction ring 13. At this time, the elastic potential energy stored on the torsion spring 19 will be released, driving the first rod 6 to rotate half a turn in the reverse direction, so that the fixed frame 9 rotates to the initial position, and then release the two first L-shaped rods 15 to ensure that the commutation mechanism can be reused.

[0051] The clamping mechanism includes four L-shaped clamping plates 22. At each of the four corners of the fixed frame 9, a second L-shaped rod 21 is slidably connected. The side walls of the four second L-shaped rods 21 located inside the fixed frame 9 are fixedly connected to the side walls of the four L-shaped clamping plates 22 respectively.

[0052] A threaded rod 23 is threadedly connected through the side wall of the first rod 6. Above the side wall of the threaded rod 23, a moving plate 24 is rotatably connected. The moving plate 24 is located inside the placement frame 7. The side wall of the moving plate 24 is rotatably connected to the side walls of the four second L-shaped rods 21 through four rotating rods 25 respectively. At the lower end of the fixed frame 9, a plurality of sliding rods 39 are fixedly connected. The side walls of the plurality of sliding rods 39 are all slidably connected to the side wall of the moving plate 24.

[0053] When fixing the battery tab located inside the fixed frame 9, at this time, rotate the threaded rod 23 forward, driving the moving plate 24 to move upward. Then, the moving plate 24 drives the four L-shaped clamping plates 22 to approach each other through the four second L-shaped rods 21, fixing the four corners of the battery tab and making the battery tab centered.

[0054] During the production process of lithium-ion batteries, when laminating the battery tabs on them, first place the battery tab inside the fixed frame 9. Then, rotate the threaded rod 23 forward, driving the moving plate 24 to move upward. Then, the moving plate 24 drives the four L-shaped clamping plates 22 to approach each other through the four second L-shaped rods 21, fixing the four corners of the battery tab and making the battery tab centered. Then, place the slider 5 in the first groove 3;

[0055] Subsequently, drive the two motors 34 to rotate forward, and then drive the two conveyor belts 32 to move from left to right through the conveyor wheels 31 (as Figure 2 shown). At this time, the two conveyor belts 32 will drive a plurality of push rods 33 to move, driving the slider 5 to slide on the inner wall of the first groove 3. At this time, the stability of the battery tab during the movement can be ensured;

[0056] During the rotation of one of the conveyor wheels 31, at this time, drive the adsorption roller 36 to rotate through the second gear 37, the third gear 38 and the rotating shaft. When the battery tab moves to the adsorption roller 36, the laminating film roll on the adsorption roller 36 will adhere to the battery tab. The laminating technology is the prior art and will not be elaborated here;

[0057] During the movement of the laminated battery tab on the left side of the toothed plate 20, at this time, the positions of the two first cylinders 27 on the two first cutting knives 28 can be adjusted, so that the side walls of the two first cutting knives 28 approaching each other are flush with the side wall of the battery tab. Then, during the movement of the battery tab, the two first cutting knives 28 can cut the excess film on the battery tab;

[0058] Subsequently, during the movement of the slider 5, when the two first wedge plates 16 are respectively in contact with the two second wedge plates 17, the two first wedge plates 16 will be driven to move away from each other. Then, the two friction plates 12 will be driven to move away from each other through the two first L-shaped rods 15, releasing the first rod 6. At this time, the first gear 18 just meshes with the toothed plate 20. Subsequently, the first rod 6 can be driven to rotate. As the slider 5 continues to move and the first gear 18 and the toothed plate 20 separate from the initial meshing state, the first gear 18 will drive the first rod 6 to rotate half a turn. Then, the first rod 6 drives the placement frame 7 to rotate half a turn, rotating the battery tab in the fixed frame 9 by half a turn, so that the uncut part of the battery tab faces the two second cutting knives 30. Subsequently, the positions of the two second cutting knives 30 can be adjusted by adjusting the two second cylinders 29, so that the side walls of the two second cutting knives 30 close to each other are flush with the side wall of the battery tab. Then, during the movement of the battery tab, the two second cutting knives 30 can cut the uncut rolled film on the battery tab;

[0059] In this way, after the battery tab is covered with a film, the excess rolled film around it can be cut during the movement of the battery tab, without the need for a stop for cutting treatment, improving production efficiency and avoiding the need for subsequent separate cutting treatment of the excess covered rolled film in the prior art;

[0060] After the covered rolled film is completely cut, the slider 5 can be taken out of the first groove 3 at this time. Then, reverse-rotate the threaded rod 23, and the four L-shaped clamping plates 22 can be driven to move away from each other, releasing the battery tab for easy removal;

[0061] Since the rotation of the first rod 6 drives the torsion spring 19 to rotate, elastic potential energy is stored in the torsion spring 19. When the first gear 18 just separates from the toothed plate 20, the two first wedge plates 16 are respectively separated from the two second wedge plates 17, so that the inner side walls of the two friction plates 12 are in close contact with the outer side wall of the friction ring 13, limiting the position of the first rod 6. At this time, the elastic potential energy on the torsion spring 19 cannot be released. Then, after the battery tab is taken out subsequently, only need to pull the two first L-shaped rods 15 outwards, so that the two friction plates 12 move away from the friction ring 13. At this time, the elastic potential energy stored on the torsion spring 19 will be released, driving the first rod 6 to rotate half a turn in the reverse direction, making the fixed frame 9 rotate to the initial position, and then release the two first L-shaped rods 15 to ensure that this commutation mechanism can be reused.

[0062] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
