TECHNICAL FIELD

[0001] The utility model relates to lithium battery liquid injection technical field especially discloses a kind of lithium battery liquid injection hole wiping mechanism. BACKGROUND

[0002] With the wide application of lithium batteries in various electronic devices and electric vehicles, the cleaning requirements for battery liquid injection holes in the manufacturing process are gradually increasing. The liquid injection hole is one of the indispensable components in the manufacturing of lithium batteries, and is usually used for the injection of electrolyte or other liquid handling steps in battery assembly. In order to ensure the performance and service life of lithium batteries, it is necessary to maintain a high degree of cleanliness in the liquid injection hole area to prevent impurities, dust or liquid residues from entering the inside of the battery, thereby affecting the quality and safety of the battery. Currently, the cleaning method of lithium battery liquid injection hole mainly relies on manual cleaning and mechanical cleaning. However, manual cleaning not only has low efficiency, but also has the risk of incomplete cleaning, especially in the case of large production batches, manual operation cannot guarantee the cleanliness of each liquid injection hole. Although mechanical cleaning improves efficiency, most of the existing mechanical cleaning methods have problems such as uneven cleaning, complex operation and large equipment footprint. SUMMARY

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a lithium battery liquid injection hole wiping mechanism.

The positioning sensing device triggers the controller unit to control the wet wiping unit to spray wiping medium to the surface of the liquid injection hole. The controller unit controls the driving mechanism to drive the wiping unit to approach the liquid injection hole of the lithium battery and perform wiping operation.

[0005] The lithium battery liquid injection hole wiping mechanism realizes efficient and accurate wiping of the liquid injection hole of the lithium battery through the cooperation of automatic positioning sensing and wet wiping unit, avoids the errors of manual operation, and improves production efficiency and wiping quality. The external lithium battery is conveyed to the rack by the conveying mechanism. After the positioning sensing device senses that the battery reaches the preset position, it automatically transmits a signal to the wet wiping unit. The wet wiping unit sprays wiping medium to the surface of the liquid injection hole. Then the wiping unit approaches the liquid injection hole through the driving mechanism and performs wiping, ensuring the cleanliness and consistency of the wiping effect of the surface of the liquid injection hole.

[0006] The wiping unit comprises a fixing frame, a lifting cylinder arranged on the fixing frame, a moving guide rail, and a wiping component arranged on the moving guide rail; the lifting cylinder drives the wiping component to reciprocally move on the moving guide rail to approach or move away from the liquid injection hole for wiping operation.

[0007] Through the cooperation of the lifting cylinder and the moving guide rail, it is ensured that the wiping component can accurately approach or move away from the liquid injection hole of the lithium battery for wiping operation, thereby realizing efficient and flexible wiping process. The lifting cylinder and the moving guide rail are installed on the fixing frame, and the wiping component is arranged on the moving guide rail. The wiping component is driven by the lifting cylinder to reciprocally move along the guide rail, so that the wiping component can approach or move away from the liquid injection hole as needed for wiping. In this way, the flexibility and accuracy of the wiping process are ensured, and effective wiping of each liquid injection hole is ensured, thereby improving the wiping quality.

[0008] The wiping component further comprises a mounting block arranged on the moving guide rail, a rotary motor arranged on the mounting block, and a wiping head connected to the output end of the rotary motor; the rotary motor drives the wiping head to rotate on the liquid injection hole to achieve cleaning effect.

[0009] The rotary wiping head can be in close contact with the surface of the liquid injection hole and provide strong cleaning effect through rotary motion, effectively removing dirt and impurities on the surface of the liquid injection hole, ensuring that the liquid injection hole remains clean and improving the wiping efficiency.

[0010] The wiping head is in the shape of a cone, and the conical wiping head better fits the shape of the liquid injection hole, thereby improving the wiping efficiency. The wiping head adopts a conical design, which can better fit the shape of the liquid injection hole, thereby improving the wiping efficiency. In a specific embodiment, the conical wiping head matches the profile of the liquid injection hole, and more uniform and thorough wiping is achieved through rotary motion. The conical structure enables the wiping head to effectively contact the inner wall of the liquid injection hole, ensuring a more delicate and efficient cleaning process, reducing residual dirt, and further improving wiping quality and production efficiency.

[0011] The wiping mechanism further comprises a non-woven fabric feeding mechanism arranged on the rack, the non-woven fabric feeding mechanism comprising a first unwinding component, a second winding component, and a compression rod, the first unwinding component and the second winding component being arranged on the two sides of the wiping component respectively, the first unwinding component unwinds the non-woven fabric material to the second winding component, the compression rod is provided in two groups, the two groups of compression rods are arranged on the two sides of the wiping head, the non-woven fabric material is flattened by the compression rod and is parallel to the end of the wiping head, and the lifting cylinder drives the wiping head to move downward and abut against the non-woven fabric material to wipe the liquid injection hole.

The wiping head moves downward through the driving mechanism, and after contacting the non-woven fabric material, the liquid injection hole is wiped with the non-woven fabric material. This design can ensure that the wiping surface is flat and the pressure is uniform, effectively improving the wiping effect and cleanliness.

[0013] The wet wiping unit includes a telescopic cylinder and a spraying component connected to the output end of the telescopic cylinder. The telescopic cylinder drives the spraying component to move back and forth to approach or move away from the external lithium battery to spray and wipe the injection hole of the external lithium battery. Non-woven fabric is soft and can adapt to different surface shapes, avoiding scratching or damaging the injection hole or other precision components. Compared with traditional cloth, non-woven fabric leaves fewer fiber fragments after wiping, reducing the risk of secondary pollution of the surface after wiping.

[0014] The spraying component is an electric micro pump that controls the spraying amount of the wiping medium. This spraying component uses an electric micro pump to accurately control the spraying amount of the wiping medium, ensuring that the amount of medium in each wiping operation can be accurately adjusted, thereby improving the cleaning effect and avoiding excessive or insufficient spraying. The electric micro pump is adjusted by an electric control system to accurately control the flow and spraying amount of the wiping medium, allowing it to be evenly and appropriately sprayed onto the surface of the injection hole.

The sponge or silica gel material has good softness and elasticity, can effectively adapt to the slight unevenness of the surface of the external lithium battery, thereby ensuring that the limiting block is in close and uniform contact with the surface of the battery and the fixing effect is more stable. The buffering performance of the material can reduce the damage to the surface of the battery during wiping, and avoid excessive pressure when the wiping head contacts the liquid injection hole, which helps to improve the wiping precision and safety. In addition, the sponge and silica gel material also has good durability and anti-aging performance, and can maintain stable limiting effect in long-term use.
