[0002] Lithium-ion batteries, as a high-efficiency and clean energy storage device, have been widely used in consumer electronics, new energy vehicles, and energy storage systems. In the manufacturing process of lithium-ion batteries, the electrode sheet, as a core component, needs to be precisely and efficiently transferred between multiple processes such as coating, rolling, die-cutting, and stacking.

[0003] Existing transfer mechanisms mostly use vacuum negative pressure adsorption, which uses a suction nozzle to adsorb the surface of the electrode to achieve gripping and transfer. However, during use, since the suction channel of the adsorption mechanism relies on a single valve for control, if there is a power interruption or leakage during the transfer process, the adsorption force will decrease, causing the electrode to fall off. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a lithium battery electrode transfer mechanism. By setting the adsorption component, it can perform mechanical self-locking after adsorbing the electrode to maintain the negative pressure channel. This process does not rely on continuous power and signal, thus improving safety.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides a lithium battery electrode transfer mechanism that solves the problem that existing transfer mechanisms cannot maintain suction in the event of power failure or signal abnormality.

[0022] By setting up the adsorption components, mechanical self-locking can be performed after the electrode is adsorbed, maintaining the negative pressure channel unobstructed. This process does not rely on continuous power and signal maintenance. Even if there is an accidental power outage or control system failure, the adsorption state will not be released, thus improving safety.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1 , Figure 2 and Figure 3 As shown, a lithium battery electrode transfer mechanism includes: two mounting brackets 1, a movable plate 3 between the two mounting brackets 1, a fixed block 4 at the bottom of the movable plate 3, a movable groove 401 at the bottom of the fixed block 4, and a movable block 402 slidably connected in the movable groove 401; an adsorption assembly, which is mounted on the fixed block 4 and includes: an adsorption block 5, a piston plate 501, an adsorption rod 502, a suction nozzle 503, and a negative pressure tube 7. Multiple hollow adsorption blocks 5 are mounted on the top of the fixed block 4, a piston plate 501 is provided inside the adsorption block 5, an adsorption rod 502 is connected to the bottom of the piston plate 501, a suction nozzle 503 is mounted on the bottom of the adsorption rod 502, and a negative pressure tube 7 is connected to one side of the adsorption block 5, with one end of the negative pressure tube 7 connected to a negative pressure device.

[0025] In use, the two mounting brackets 1 are installed between the two processes respectively, so that the adsorption component can transfer the electrode from the previous process to the next process. Then, when transferring the electrode, the adsorption component adsorbs the electrode and carries it to the next process.

[0026] Reference Figure 2As shown, a motor 2 is installed on one side of one of the mounting brackets 1, and a threaded rod 201 is driven and connected to one side of the motor 2. A sliding rod 202 is connected between the two mounting brackets 1. A threaded hole that meshes with the threaded rod 201 is opened on the moving plate 3. A through hole that mates with the sliding rod 202 is opened on the moving plate 3. An electric push rod 301 is installed on the top of the moving plate 3. A connecting frame 302 is connected to the bottom of the electric push rod 301. The connecting frame 302 is arranged in an inverted U-shape. The bottom end of the connecting frame 302 is connected to the fixing block 4.

[0027] When transferring the electrode, the motor 2 drives the threaded rod 201 to rotate, so that the threaded rod 201 drives the moving plate 3 to move under the action of the threaded hole thread engagement. However, due to the setting of the through hole and the slide rod 202, the moving direction of the moving plate 3 is limited, so that the moving plate 3 can only translate along the axis of the slide rod 202, thereby driving the fixed block 4 and the adsorption assembly to move to the next process position.

[0028] Reference Figure 3 and Figure 6 A return spring 505 is connected to the bottom of the piston plate 501. The return spring 505 is sleeved on the outside of the adsorption rod 502. An air suction pipe is opened inside the adsorption rod 502 and is connected to the suction nozzle 503. A through hole 504 communicating with the air suction pipe is opened on one side of the adsorption rod 502. An arc-shaped block 506 is connected to the top of the piston plate 501. A slot 507 is opened on the arc-shaped block 506. An equipment block 6 is connected to one side of the adsorption block 501. An electromagnet 601 is installed inside the equipment block 6. An iron block 602 is provided on one side of the electromagnet 601. A locking block 603 is connected to one side of the iron block 602. A connecting spring is connected between the iron block 602 and the equipment block 6.

[0029] Both the fixed block 4 and the movable block 402 are equipped with contact sensors at their bottoms, and the sensors are connected to an external main controller to provide feedback on the downward movement distance of the fixed block 4, thereby controlling the extension of the electric push rod 301. When adsorbing the electrode, the fixing block 4 is moved above the electrode. Then, the electric push rod 301 drives the connecting frame 302 and the fixing block 4 to move down. At this time, the suction nozzle 503 contacts the surface of the electrode. Then it continues to move down until the contact sensor at the bottom of the movable block 402 contacts the platform where the electrode is located. The contact sensor transmits a signal to the external main controller, which controls the extension of the electric push rod 301. At this time, the suction nozzle 503 is lifted by the electrode, which in turn drives the adsorption rod 502 and the piston plate 501 to move up. This makes the space below the piston plate 501 communicate with the negative pressure tube 7. The space below the piston plate 501 is also connected to the suction nozzle 503 through the through hole 504 and the suction tube. The negative pressure tube 7 draws gas, allowing the suction nozzle 503 to generate suction to adsorb the electrode. Meanwhile, one end of the locking block 603 is provided with an inclined surface, so that when the piston plate 501 moves the arc-shaped block 506 upward, the arc-shaped block 506 contacts the inclined surface of the locking block 603 and squeezes the locking block 603 into the device block 6 until the locking block 603 corresponds to the position of the locking slot 507. At this time, the locking block 603 rebounds under the action of the connecting spring force, so that the locking block 603 is inserted into the locking slot 507, completing the positioning of the arc-shaped block 506 and the piston plate 501, so as to maintain the connection between the negative pressure tube 7 and the suction nozzle 503 and maintain the adsorption of the electrode sheet; After the electrode is transferred to the lowering process, the connecting frame 302 and the fixing block 4 are moved down by the electric push rod 301, placing the electrode on the worktable of the next process. As it continues to move down until the bottom of the fixing block 4 contacts the worktable, the locking block 603 is squeezed into the equipment block 6 by the locking groove 507. As the fixing block 4 moves down, the piston plate 501 moves above the locking block 603. The top of the equipment block 6 has an air hole, which allows the space below the piston plate 501 to be connected to the outside through the air hole on the equipment block 6, eliminating the low-pressure suction in the space below the piston plate 501 and thus releasing the adhesion to the electrode. Then, the fixing block 4 and the connecting frame 302 are moved up and reset by the electric push rod 301, and the electromagnet 601 is energized to generate a magnetic force to attract the iron block 602, keeping the locking block 603 in the equipment block 6 so that the piston plate 501 can be reset under the action of the return spring 505, and preventing the locking block 603 from obstructing the reset of the piston plate 501.

[0030] All electrical components mentioned in the article are electrically connected to an external controller and power supply. The controller can be a conventional known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the article.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
