Technical Field
[0001] The utility model relates to the technical field of liquid injection machines, in particular to a liquid injection machine with an anti-drip structure. Background Art
[0002] A lithium battery filling machine is a specialized piece of equipment that plays a key role in the lithium battery production process. Its primary function is to inject precisely measured amounts of electrolyte into the battery cells. Through a high-precision filling system and strict control procedures, this ensures even and appropriate electrolyte delivery into the cells, crucially ensuring proper battery charging and discharging, as well as optimal performance. This equipment typically features advanced automated control technology, enabling efficient, stable, and precise filling operations, making it a crucial tool for improving the quality and efficiency of lithium battery production.
[0003] According to a disclosed lithium battery filling nozzle with a leakage-proof function (publication number: CN220934356U7), the above application adopts the design of the filling structure, so that when the lithium battery filling nozzle is connected to the liquid inlet and liquid is injected into the lithium battery, the supporting circular plate is adsorbed and fixed to the metal around the liquid inlet by a magnetic sheet, so that the operation of hand-held filling is no longer required, thereby improving the functionality of this lithium battery filling nozzle. At the same time, the design of the sealing ring fills the gap between the filling nozzle and the liquid inlet to avoid overflow and leakage.
[0004] The above method uses a magnet to attract and fix the supporting circular plate to the metal around the liquid inlet, thereby filling the gap between the liquid injection nozzle and the liquid inlet. However, after long-term use, this type of nozzle may demagnetize the magnet and become difficult to maintain, making it impractical. In addition, this nozzle has high restrictions in various working environments. Therefore, a liquid injection machine with an anti-drip structure is proposed. Utility Model Content

[0010] Preferably, the inner wall of the nozzle is fixedly connected to a hose, and the nozzle is driven up by the table to shrink the hose. The hose is slidably connected to the inner wall of the support platform, and the outer wall of the hose is slidably connected to a fixed block, and the fixed block is fixedly connected to the top of the support platform.
[0011] Preferably, the outer wall of the fixed block is fixedly connected to a spring, the outer wall of the spring is fixedly connected to a moving block, the outer wall of the moving block is fixedly connected to a top plate, and the outer wall of the moving block is slidably connected to a top block, and the top plate can squeeze the hose by squeezing the moving block through the top block.
[0012] Preferably, a sliding groove is provided on the outer surface of the support platform, and the moving block is slidably connected to the inner wall of the sliding groove.

[0014] Compared with the prior art, the present invention provides a liquid injection machine with an anti-drip structure, which has the following beneficial effects:
[0015] 1. The liquid injection machine with an anti-drip structure is designed to avoid cumbersome liquid injection operations. The cylinder is activated to cause the piston rod to drive the table to rise, and the support plate drives the top block to rise. The top block rises through the through slot and touches the moving block. The moving block is squeezed by the top block and moves in the slide slot. The spring is squeezed and deformed, and the top plate squeezes the outer surface of the hose. The fixed block cooperates with the squeezing of the top plate to block the liquid in the hose and stop injecting the liquid from the nozzle. When the cylinder drives the table to descend, the spring rebound force moves the top plate away from the hose, so that the liquid resumes injection, making it very easy to prevent leakage during operation.
[0016] 2. The liquid injection machine with an anti-drip structure is designed to avoid erosion caused by liquid dripping when the liquid injection machine is not in use. The piston rod rises, and the table drives the slide rod to move upward. The slide rod slides in the arc groove, the rotating rod rotates on the support table, and the rocker arm rotates close to the nozzle. When the cylinder stops running, the liquid receiving tank moves to the bottom of the nozzle. In the event of accidental shaking or reduced air pressure, this prevents liquid from dripping from the nozzle, thereby protecting the appearance of the liquid injection machine and the battery box.

The inner wall of the hose 55 is slidably connected to a fixed block 56 on the outer wall, and the fixed block 56 is fixedly connected to the top of the support platform 1. The outer wall of the fixed block 56 is fixedly connected to a spring 57. The outer wall of the spring 57 is fixedly connected to a moving block 58. The outer wall of the moving block 58 is fixedly connected to a top plate 59. The outer wall of the moving block 58 is slidably connected to the top block 53. The moving block 58 is squeezed by the top block 53, so that the top plate 59 can squeeze the hose 55. A slide groove 510 is provided on the outer surface of the support platform 1. The moving block 58 is slidably connected to the inner wall of the slide groove 510. The force is applied by the moving block 58 and can slide on the inner wall of the slide groove 510. A through groove 511 is provided on the outer surface of the support platform 1. The inner wall of the through groove 511 is slidably connected to the top block 53.
[0024] Specifically, the liquid receiving mechanism 6 includes a slide rod 61, a rotating rod 62, an arc groove 63, a rocker rod 64, and a liquid receiving groove 65; the outer wall of the table 51 is fixedly connected to the slide rod 61, the bottom of the support platform 1 is rotatably connected to the rotating rod 62, the outer surface of the rotating rod 62 is provided with an arc groove 63, the inner wall of the arc groove 63 is slidably connected to the slide rod 61, the outer wall of the rotating rod 62 is fixedly connected to the rocker rod 64, and the outer wall of the rocker rod 64 is provided with a liquid receiving groove 65.
[0025] Working principle: When the injection operation is completed, the cylinder 3 is started to make the piston rod 4 drive the table 51 to rise, and the support plate 52 drives the top block 53 to rise. The top block 53 rises through the through groove 511 and touches the moving block 58. The moving block 58 is squeezed by the top block 53 and moves in the slide groove 510.

The fixed block 56 cooperates with the squeezing of the top plate 59 to block the liquid in the hose 55 and the nozzle 54 stops injecting liquid. When the cylinder 3 drives the table 51 to descend, the rebound force of the spring 57 makes the top plate 59 move away from the hose 55, so that the liquid starts to be injected again, which makes it very easy to prevent leakage during operation.
[0026] When the piston rod 4 rises, the table 51 drives the slide rod 61 to move upward, and the slide rod 61 slides on the inner wall of the arc groove 63, causing the rotating rod 62 to rotate on the inner wall of the support platform 1.

When the cylinder 3 stops running, the liquid receiving groove 65 on the rocker arm 64 moves to the bottom of the nozzle 54, thereby preventing liquid from dripping from the nozzle 54 when accidental shaking or air pressure drop occurs, thereby protecting the appearance of the liquid injection machine and the battery box.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
