Description

Technical Field

[0001] The invention relates to the technical field of electrolyte filling, in particular to electrolyte uniform filling equipment with multiple filling heads. Background Art

[0002] Battery electrolyte is the carrier of ion transmission in the battery, generally composed of lithium salt and organic solvent. The electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, and is the guarantee for the lithium-ion battery to obtain advantages such as high voltage and high specific energy. The electrolyte is generally made of high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials, prepared under certain conditions and in a certain proportion;

[0003] In the battery production process, electrolyte filling is one of the main steps of battery production. Existing electrolyte filling devices, such as an electrolyte filling device with publication number CN213340669U, can automatically fix the battery when it is placed, so as to facilitate the delivery of electrolyte into the battery, which is conducive to improving the filling efficiency.

[0004] In actual use of the above-mentioned existing electrolyte filling device, the electrolyte discharge mainly relies on its own gravity, which leads to a slow electrolyte filling speed and affects the filling efficiency. After the filling is completed, it is difficult to avoid a certain amount of electrolyte remaining on the inner wall of the infusion tube, which is difficult to completely empty. When the infusion tube is separated from the battery, the electrolyte dripping on the inner wall of the infusion tube will cause corrosion to the equipment, thereby affecting the service life of the equipment. Therefore, in view of the above problems, a multi-filling head electrolyte uniform filling device is designed to better meet the actual use needs. Summary of the invention

Through the sliding action between the inclined panel and the convex shaft, a basic force can be provided for the movement of the movable plate, and by limiting the distance between the upper edge of the inclined surface of the inclined panel and the convex shaft, it can be ensured that after the battery is clamped, the filling rod cooperates with the battery to realize liquid injection, thereby ensuring the normal operation of the device.

[0029] A support leg 101 is fixed to the lower end surface of the workbench 1, and a positioning plate 102 is fixed to the upper end surface of the workbench 1, and the positioning plate 102 contacts the battery 8 to achieve a positioning effect; a motor 5 is also fixed to the back plate 2, and a gear 6 is fixed to the output end of the motor 5; the positioning mechanism 7 is composed of a movable plate 701, a convex shaft 702, a slide bar 703, a first spring 704, a connecting rod 705, a clamping plate 706, an anti-slip strip 707 and a cross bar 708. The movable plate 701 is symmetrically arranged on the upper side of the workbench 1, and a convex shaft 702 is fixed to the movable plate 701, and a slide bar 703 is also symmetrically fixed to the rear end surface of the movable plate 701, and the slide bar 703 is symmetrically fixed to the back plate 2 at the same time, and the slide bar 703 and the back plate 2 are slidably connected; one end of the first spring 704 is fixed to the slide bar 703, and the other end of the first spring 704 is fixed to the back plate 2; the movable plate 701 is rotatably connected to the connecting rod 7 05, and the other end of the connecting rod 705 is rotatably connected to the clamping plate 706; the clamping plate 706 is evenly fixed with anti-slip strips 707, and the clamping plate 706 and the cross bar 708 are slidably connected, and the cross bar 708 is fixed on the workbench 1; the movable frame 9 is also fixed with a convex rack 901, and the convex rack 901 meshes with the gear 6 to realize the transmission effect; the upper end surface of the movable frame 9 is also vertically fixed with a vertical rod 902, and the vertical rod 902 and the fixed plate 903 are slidably connected, and the fixed plate 903 is fixed to the front side of the back plate 2; the rear side of the movable frame 9 is also fixed with an inclined plate 904, and the inclined plate 904 and the workbench 1 are slidably connected, and the inclined plate 904 and the convex shaft 702 are slidably connected, and at the same time, the distance between the upper edge of the inclined surface of the inclined plate 904 and the convex shaft 702 is greater than the distance between the lower end surface of the perfusion rod 1004 and the battery 8;

[0030] When using the multi-filling head electrolyte uniform filling equipment, such as Figure 1-Figure 5As shown, at this time, the two batteries 8 on the right side are in the electrolyte perfusion state, and then the two batteries 8 that need to be perfused with electrolyte are placed on the left side of the workbench 1, and the batteries 8 are just located between the two clamping plates 706, and the rear end of the batteries 8 is in contact with the positioning plate 102 to achieve front and rear positioning. After the electrolyte perfusion of the two batteries 8 on the right side is completed, the motor 5 is controlled to drive the gear 6 to rotate clockwise, so that the left movable frame 9 and the left perfusion mechanism 10 can be moved up, and the right movable frame 9 and the right perfusion mechanism 10 can be moved down. With the sliding guide effect between the vertical rod 902 and the fixed plate 903, the stability of the movement of the movable frame 9 and the perfusion mechanism 10 can be guaranteed. When the movable frame 9 moves downward, the inclined plate 904 is driven to move downward at the same time. When the inclined plate 904 contacts and slides with the convex shaft 702, the movable plate 701 is forced to move forward. With the sliding guide effect between the slide bar 703 and the back plate 2, the stability of the movement of the movable plate 701 can be guaranteed. When the movable plate 701 moves forward, with the transmission effect of the connecting rod 705, The two adjacent clamping plates 706 can be forced to move toward each other, so that the distance between the two clamping plates 706 is reduced, until the anti-slip strips 707 on the two clamping plates 706 contact the battery 8 to achieve the left and right limit of the battery 8. At this time, the upper end of the inclined surface of the inclined plate 904 is just in contact with the convex shaft 702, so that the positioning function of the battery 8 can be achieved, and at this time the injection rod 1004 is just located on the upper side of the battery 8. The right movable frame 9 and the right injection mechanism 10 continue to move downward, so that the injection rod 1004 cooperates with the battery 8 to achieve the electric The electrolyte perfusion function is realized, and during the upward movement of the left movable frame 9 and the left perfusion mechanism 10, when the inclined plate 904 is separated from the convex shaft 702, the movable plate 701 and the clamping plate 706 are reset under the elastic action of the first spring 704, so that the limit of the left battery 8 can be released, and the battery 8 perfused with electrolyte can be transferred conveniently. In summary, by controlling the motor 5 to drive the gear 6 to rotate forward and reverse, the continuous perfusion of the electrolyte of the batteries 8 on the left and right sides can be realized, and the perfusion efficiency is effectively improved;

[0031] The filling mechanism 10 includes a buffer cylinder 1001, a liquid level sensor 1002, a solenoid valve 1003, a filling rod 1004, a piston rod 1005, a sealing cylinder 1006, a piston head 1007, a second spring 1008 and an air intake check valve 1009. The buffer cylinder 1001 is fixed symmetrically on the lower end surface of the movable frame 9. The buffer cylinder 1001 is connected to the delivery pump 4 through a conduit. The liquid level sensor 1002 is fixed in the buffer cylinder 1001. The buffer cylinder 1001 01 is fixed with a solenoid valve 1003 at the lower end, and a filling rod 1004 is connected to the lower end of the solenoid valve 1003. A piston rod 1005 is fixed to the upper end of the buffer cylinder 1001. The piston rod 1005 is slidably connected to the movable frame 9 and the sealing cylinder 1006. The sealing cylinder 1006 is connected to the buffer cylinder 1001 through a conduit. The connection position of the conduit and the buffer cylinder 1001 is located above the liquid level sensor 1002, and the internal diameter of the buffer cylinder 1001 is smaller than that of the liquid level sensor 1002. The piston head 1007 is fixed to the inner diameter of the sealing cylinder 1006, and the piston head 1007 is slidably connected in the sealing cylinder 1006. One end of the second spring 1008 is fixed to the piston head 1007, and the other end of the second spring 1008 is fixed in the sealing cylinder 1006. The sealing cylinder 1006 is also fixed with an air intake check valve 1009. When there is electrolyte in the buffer cylinder 1001, the gravity and air pressure of the electrolyte make the buffer cylinder 1001, the piston rod 1005 and the piston head 1007 move downward. At this time, the second spring 1008 is forced to shrink. During the electrolyte perfusion process, the piston head 1007 moves upward through the elastic action of the second spring 1008, so that the gas in the sealing cylinder 1006 enters the buffer cylinder 1001, so that the electrolyte in the buffer cylinder 1001 is quickly discharged, and under the action of the airflow, the electrolyte in the buffer cylinder 1001 can be completely discharged;

[0032] During the electrolyte filling process, Figure 7As shown, at this time, the buffer cylinder 1001 at the lower end surface of the right movable frame 9 is in an unloaded state. By controlling the start of the delivery pump 4, the electrolyte in the storage box 3 can be delivered to the buffer cylinder 1001. At this time, the solenoid valve 1003 at the lower side of the buffer cylinder 1001 is in a closed state. With the injection of electrolyte, the air in the buffer cylinder 1001 enters the sealing cylinder 1006 through the conduit. At this time, the piston head 1007 moves downward under the action of air pressure, and the sliding guide effect between the piston rod 1005 and the movable frame 9 and the sealing cylinder 1006 can ensure the stability of the movement of the piston head 1007, and the second spring 1008 is forced to shrink, and as the electrolyte enters the cache cylinder 1001, the gravity of the cache cylinder 1001 and the electrolyte can drive the piston rod 1005 and the piston head 1007 to move further downward, and cooperate with the air intake check valve 1009 to make the volume of air entering the sealing cylinder 1006 larger than the volume of air discharged from the cache cylinder 1001, until the electrolyte level in the cache cylinder 1001 contacts the liquid level sensor 1002, at which time the electrolyte perfusion is stopped, thereby realizing the quantitative storage of the electrolyte, and when the right movable frame 9 moves downward, it drives the perfusion rod 1004 to move downward and cooperate with the battery 8 When the electromagnetic valve 1003 is opened, the elastic effect of the second spring 1008 can make the piston head 1007 move upward to discharge the air in the sealing cylinder 1006. At this time, the air in the sealing cylinder 1006 enters the buffer cylinder 1001. Under the action of air pressure, the electrolyte in the buffer cylinder 1001 can be quickly discharged. As the electrolyte in the buffer cylinder 1001 is discharged, the weight is reduced, and the piston head 1007 can be completely reset under the action of the second spring 1008, so that the air in the sealing cylinder 1006 is completely discharged into the buffer cylinder 1001. The air volume inside is larger than the air volume discharged from the cache barrel 1001, so that after the electrolyte in the cache barrel 1001 is completely discharged, a certain amount of air will be discharged outward through the cache barrel 1001 and the filling rod 1004. At this time, under the action of the airflow, the electrolyte adhered to the inner wall of the cache barrel 1001 and the filling rod 1004 can be discharged, thereby ensuring that the electrolyte is completely discharged and avoiding corrosion damage to the equipment caused by the dripping of electrolyte adhered to the inner wall of the cache barrel 1001 and the filling rod 1004, thereby extending the service life of the equipment. This is the working principle of the electrolyte uniform filling equipment with multiple filling heads.
