Description

Technical Field

[0001] The invention relates to the field of battery production, in particular to a battery post-liquid filling wiping and nailing integrated device. Background Art

[0002] The production process of lithium batteries is relatively complicated, and the process mainly includes three stages:

[0003] The front-end process is to process the raw materials into pole pieces, which go through processes such as coating, rolling, slitting, sheeting, and die-cutting, among which the core process is coating; the middle-end process is to process the pole pieces into unactivated cells, which need to go through processes such as winding or lamination, shell welding, liquid injection, and sealing, among which winding and lamination are the core processes; the back-end process is to activate the cells to make them into finished battery packs, and then finally enter the battery factory through assembly of PACK, including processes such as cleaning, drying storage, testing, chemical composition and capacity, and finally enter the downstream production line, among which chemical composition and capacity is the core process;

[0004] When the battery is being filled, electrolyte may remain on the outer edge of the filling hole. If it is not removed in time, it may cause safety hazards such as battery performance degradation and internal short circuit during battery use. At the same time, the degree of wiping and cleaning of the electrolyte on the outer edge of the filling hole will also affect the welding quality of the subsequent sealing nails. Wiping can remove electrolyte residues at the filling port and its surroundings, and reduce welding defects during nailing, such as cold welding or loose welding, which is crucial to ensure the sealing and safety of the battery.

[0005] At present, the operations of wiping the electrolyte on the outer edge of the battery filling hole and nailing are carried out separately. That is, after the electrolyte on the outer edge of the filling hole of each battery is wiped, it is transmitted to the nailing link. During the transmission process, it will take up some time and the efficiency is low.

[0074] Working principle: In this embodiment, a conveying unit, a transmission unit, a wiping unit and a nailing unit are provided. The conveying unit includes a feeding conveying component and a discharging conveying component. The feeding conveying component is responsible for feeding the battery after the injection is completed, that is, the battery is conveyed to the conveying unit. The battery is conveyed through the wiping unit and the nailing unit in sequence through the conveying component to clean the residual electrolyte on the outer edge of the battery injection hole and install the sealing nail 23. Then, the battery after wiping and nailing is conveyed away from the wiping and nailing integrated device through the discharging output component;

[0078] A stabilizing component is provided on the conveyor belt 3, namely, two symmetrically arranged guide plates 6, which can clamp and stabilize the lower half of the battery, that is, stabilize the battery on the conveyor belt 3, and when the conveyor belt 3 is converted from a stopped state to a moving state, the battery can still be stabilized, and the ends of the two symmetrically arranged guide plates 6 are arranged in a flared shape, that is, the ends of the guide plates 6 facing the feed conveyor belt 4 and the discharge conveyor belt 5 are arranged in a flared shape, so as to facilitate the movement of the battery to the conveyor belt 3 and accurately place it between two adjacent guide plates 6;

[0079] The limit plate 1 is used to limit the position of the battery on the conveyor belt 3. When the battery is pushed from the feed conveyor belt 4 to the conveyor belt 3, the battery's own inertia will continue to move. At this time, under the restriction of the limit plate 1, the battery can be limited on the conveyor belt 3, so that the injection hole of the battery can be opposite to the adsorption component and the blowing component; the adsorption component in this embodiment can use some negative pressure equipment, such as a pipe connected to a negative pressure pump, which can extract the residual electrolyte on the outer edge of the injection hole, and can also extract the residual foreign matter on the outer edge of the injection hole; and the blowing component can use some positive pressure equipment, such as a pipe connected to an air pump, which can further clean the outer edge of the injection hole and improve the cleanliness of the outer edge of the injection hole;

When the No. 1 cylinder 9 drives the lifting plate 10 to move downward, the lifting plate 10 drives the bellows 12 to move downward, so that the lower end of the bellows 12 is pressed against the injection hole. Then the negative pressure pump connected to the bellows 12 is started, and the residual electrolyte on the outer edge of the injection hole is extracted. That is, the residual electrolyte on the outer edge of the injection hole is wiped and cleaned by extraction. Compared with wiping with cloth, the cleaning method is simple and the cleanliness is higher.

[0081] The blowing assembly provided in this embodiment uses a blowing pipe 13, and the blowing port of the blowing pipe 13 is in a horizontal state. When the No. 1 cylinder 9 drives the blowing pipe 13 to move down to one side of the battery through the lifting plate 10, the blowing port of the blowing pipe 13 is horizontally pointed above the injection hole, and the high-pressure gas further blows and cleans the outer edge of the injection hole to improve the cleanliness;

[0082] The battery is conveyed to the bottom of the rotating assembly by the conveyor belt 3, and then the motor 14 drives the active gear 15, and the active gear 15 drives the driven gear 16 to rotate, and drives the two grabbing assemblies to alternately grab the sealing nail 23 on the feeding assembly, and at the same time, the grabbing assembly installs the grabbed sealing nail 23 at the injection hole position;

[0083] The motor 14 is a forward and reverse motor 14, and the forward and reverse rotations are performed alternately in sequence; the No. 2 cylinder 17 drives the suction cup 19 to move down to the end of the slide plate 21, that is, the suction cup 19 moves down to the upper surface of the sealing nail 23 on the end of the slide plate 21, and the suction cup 19 can absorb the sealing nail 23 with its adsorption force, and then the No. 2 cylinder 17 drives the sealing nail 23 to move up through the suction cup 19, and when the suction cup 19 moves down to absorb the sealing nail 23, another No. 2 cylinder 17 pushes the sealing nail 23 absorbed by the suction cup 19 to the injection hole position of the battery , and under the pressure of the suction cup 19, the sealing nail 23 is squeezed into the injection hole; one of the No. 2 cylinders 17 drives the suction cup 19 to move down to absorb the sealing nail 23 on the slide plate 21, and the other No. 2 cylinder 17 drives the suction cup 19 to move down and squeeze the sealing nail 23 on the suction cup 19 into the injection hole, the two No. 2 cylinders 17 are synchronized, and then the motor 14 drives the two No. 2 cylinders 17 to rotate and exchange positions, and continue to absorb the sealing nail 23, and install the sealing nail 23, and repeat the above actions;

[0084] A pressure rod 24 is arranged on the top surface of the suction cup 19. When the seal is squeezed into the injection hole, the pressure rod 24 plays the role of squeezing the sealing nail 23, and can effectively and quickly squeeze the sealing nail 23 into the injection hole smoothly, avoiding the problem that the suction cup 19 is squeezed, deformed and damaged by squeezing the sealing nail 23 through the suction cup 19;

[0085] The No. 3 cylinder 26 is used to push the semi-ring body 25, and the two No. 3 cylinders 26 push the semi-ring body 25 to move synchronously toward the center, so that before the No. 2 cylinder 17 pulls the sealing nail 23 and rotates to exchange positions, the two semi-ring bodies 25 are pressed on the outer ring of the sealing nail 23, and the sealing nail 23 is pressed in the center of the lower surface of the suction cup 19, that is, the axis of the suction cup 19 and the axis of the sealing nail 23 are in a coaxial state, which helps the sealing nail 23 to be smoothly installed in the injection hole;

[0086] The guard plate 27 is used to constrain the battery so that the battery can move along the specified route to the conveyor belt 3, and the battery can be stably transferred away from the integrated wiping and nailing device; and a roller 28 is arranged on the inner wall of the guard plate 27 to make the battery move more smoothly. At the same time, a roller 28 can also be arranged on the surface of the limit plate 1 to reduce the friction component between the battery and the limit plate 1, which helps to move the battery smoothly.
