Abstract
Description
Technical Field
[0001] The utility model relates to the technical fields related to battery electrode sheet transfer and the like, in particular to a transfer tooling for a solid-state battery electrode sheet. Background Art
[0002] A solid-state lithium battery is a battery technology that uses a solid-state electrolyte to replace the liquid electrolyte in a traditional lithium-ion battery. The solid-state electrolyte transports lithium ions between the positive and negative electrodes and the separator, playing a role in the conversion and storage between electrochemical energy and chemical energy. Compared with traditional liquid electrolytes, solid-state electrolytes have the advantages of high energy density, good safety, fast charging, and long cycle life.
[0003] A sulfide all-solid-state battery conducts lithium ions through solid-solid contact, and the positive and negative electrodes are isolated by an electrolyte membrane. To meet the ionic conductivity of the electrolyte membrane, too much binder cannot be added, resulting in poor mechanical properties of the membrane, which needs to be coated on a current collector and transferred to the surface of the battery negative electrode through a transfer process.
[0004] Currently, the battery negative electrode and the electrolyte membrane are highly adhered by static pressure. After the static pressure is completed, the current collectors on both sides of the electrolyte membrane of the battery negative electrode need to be removed. Currently, the method of removing the current collector of the electrolyte membrane is to first remove the current collector of the electrolyte membrane on one side of the battery negative electrode. However, during the static pressure process, more stress will accumulate inside the battery electrode sheet. After removing the current collector of the electrolyte membrane on one side of the battery negative electrode, due to the stress, the other side of the battery negative electrode will bend, resulting in the rupture of the electrolyte membrane when removing the current collector.

[0027] As Figures 1 to 3 shown, a full-solid-state battery electrode transfer tooling of a preferred embodiment is shown, which includes: two brackets 1, a first rubber roller group 2, a handle 5, a transmission device 4, and a second rubber roller group 3.
[0028] The two brackets 1 are oppositely arranged; the transmission device 4 is installed on one bracket 1, and both ends of the first rubber roller group 2 and both ends of the second rubber roller group 3 are respectively installed on the two brackets 1; the handle 5 extends into one bracket 1 and is installed on the transmission device 4, and the handle 5 is in transmission connection with the first rubber roller group 2 and the second rubber roller group 3 through the transmission device 4. A gap 6 is provided between the first rubber roller group 2 and the second rubber roller group 3. The handle 5 can drive the first rubber roller group 2 and the second rubber roller group 3 to rotate or move in opposite directions relative to the gap 6 through the transmission device 4, so as to remove the current collectors of the electrolyte films on both sides of the battery electrode 7 through the gap 6.
[0029] In the actual use process, the size of the gap 6 is adjusted. When the battery electrode 7 passes through the gap 6, the current collectors of the electrolyte films on both sides of the battery electrode 7 can be removed simultaneously by the rotational force or pressure between the first rubber roller group 2 and the second rubber roller group 3, effectively reducing the bending of the battery electrode 7, thereby avoiding cracking and material dropping at the edge of the battery electrode 7, effectively improving the transfer success rate of the battery negative electrode, and reducing losses.
[0030] The present utility model further has the following implementation manners on the above basis:

The first sprocket 44 and the third sprocket 47 are respectively connected to the first rubber roller group 2 and the second rubber roller group 3, so that the first rubber roller group 2 and the second rubber roller group 3 rotate in opposite directions with respect to the relative gap 6. Specifically, a worker rotates the handle 5. The rotation of the handle 5 drives the first sprocket 44 to rotate. The rotation of the first sprocket 44 drives the chain 45 to rotate. The rotation of the chain 45 drives the second sprocket 46 to rotate. The rotation of the second sprocket 46 drives the third sprocket 47 to rotate, so that the first sprocket 44 and the third sprocket 47 can rotate in opposite directions.
[0032] Further, a transfer tooling for all-solid-state battery electrode sheets, wherein the first rubber roller group 2 includes: a first transmission shaft 27, a second transmission shaft, a first rubber roller, and a second rubber roller; the first transmission shaft 27 is installed on the first sprocket 44.

The first transmission shaft 27 and the second transmission shaft are drivingly connected by a first belt. The second rubber roller is sleeved on the second transmission shaft. Specifically, when in use, the first sprocket 44 drives the first transmission shaft 27 to rotate. The first transmission shaft 27 drives the second transmission shaft to rotate through the first belt, so that the first transmission shaft 27 and the second transmission shaft rotate in the same direction, so that the first rubber roller and the second rubber roller can rotate in the same direction. Finally, through the rotational force, the current collector of the electrolyte film on the upper surface of the battery electrode sheet is removed.
[0033] Further, a transfer tooling for all-solid-state battery electrode sheets, wherein the second rubber roller group includes: a third transmission shaft 28, a fourth transmission shaft, a third rubber roller, and a fourth rubber roller; the third transmission shaft 28 is installed on the third sprocket 47.

The third transmission shaft 28 and the fourth transmission shaft are drivingly connected by a second belt. The fourth rubber roller is sleeved on the fourth transmission shaft. Specifically, the rotation of the third sprocket 47 drives the third transmission shaft 28 to rotate. The third transmission shaft 28 drives the fourth transmission shaft to rotate through the second belt, so that the third transmission shaft 28 and the fourth transmission shaft can rotate simultaneously. Finally, through the rotational force, the current collector of the electrolyte film on the lower surface of the battery electrode sheet is removed.

The first rubber roller group 2 is installed on the first rack 42, and the second rubber roller group is installed on the second rack 43, so that the first rubber roller group 2 and the second rubber roller group 3 can move relative to a gap 6. Specifically, a worker rotates the handle 5, and the handle 5 drives the gear 41 to rotate. Since the first rack 42 and the second rack 43 are installed on the opposite sides of the same axis of the gear 41, when the gear 41 rotates, the gear 41 drives the first rack 42 and the second rack 43 to move in opposite directions, thereby driving the first rubber roller group 2 and the second rubber roller group 3 to move in opposite directions. When the first rubber roller group 2 and the second rubber roller group 3 move simultaneously towards the direction of the gap 6, the current collectors of the electrolyte films on both sides of the battery electrode sheet 7 are removed by the pressure of the first rubber roller group 2 and the second rubber roller group 3 on the gap 6.

Specifically, the first roller 22 presses against the second roller 23, and the first roller 22 and the second roller 23 are installed on the first rack 42 through the first connection seat 21. When the first rack 42 moves, the first roller 22 and the second roller 23 move simultaneously.
[0037] Furthermore, a transfer tooling for all-solid-state battery electrode sheets, wherein the second rubber roller group 3 includes: a second connection seat 24, a third roller 25, and a fourth roller 26; the second connection seat 24 is installed on the second rack 43.

Specifically, the fourth roller 26 can press against the third roller 25, and the third roller 25 and the fourth roller 26 are installed on the second rack 43 through the second connection seat 24. When the second rack 43 moves, the third roller 25 and the fourth roller 26 can move simultaneously.
[0038] In a preferred embodiment, the above slider structure includes: a slide rail and a plurality of sliders. The slide rail is longitudinally installed on another bracket 1 away from the handle 5. The first roller 22 and the second roller 23 are slidably installed on the slide rail through the same slider.

This minimum distance can ensure that the electrolyte membranes on both sides of the battery electrode sheet can pass through, but the current collectors cannot pass through, so that the current collectors on both sides are removed at the same time.
[0039] Further, a transfer tooling for a solid-state battery electrode sheet, further comprising: two chassis 8; the bottom end of each bracket 1 is installed on a chassis 8. Specifically, the stability of the two brackets 1 is ensured by the chassis 8.
[0040] Further, a transfer tooling for a solid-state battery electrode sheet, wherein the handle 5 is formed by bending outward twice from a bracket 1, and an anti-slip portion is provided at one end of the handle 5 away from the bracket 1.
