Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a lithium battery liquid filling cup conveying and cleaning mechanism. Background Art

[0002] With the continuous advancement of technology in the field of lithium battery production, mechanical automation has gradually replaced traditional manual labor production. Some battery manufacturing companies keep pace with the times and use injection machines to automate the battery injection process during battery production and processing. After the battery is injected with electrolyte, some electrolyte usually remains in the injection cup, which requires the replacement, cleaning, and transportation of the injection cup or other injection equipment.

[0003] The existing cleaning devices for liquid injection equipment have the following defects: 1. It can only realize automatic cleaning of the liquid injection cup, and cannot realize the work of transporting, moving and cleaning the liquid injection cup in an integrated manner. The entire liquid injection process of the battery also includes intermediate steps such as taking out the liquid injection cup, then putting the liquid injection cup into the cleaning equipment for cleaning, and finally putting the liquid injection cup back in. The devices that complete these processes are usually set up separately and arranged in a dispersed manner. These intermediate processes greatly reduce the production efficiency of the battery. 2. If the liquid injection cup is not cleaned thoroughly enough, there will be residual electrolyte attached to the wall of the cup or crystals will block the liquid outlet. Incomplete cleaning will also make it difficult to clean and maintain the liquid injection cup in the later stage. In addition, when different electrolytes need to be injected, the same liquid injection cup is used, and incomplete cleaning will also cause cross-infection of the electrolyte. Utility Model Content

[0008] The transport mechanism comprises a guide rail, a servo motor and a support seat; the guide rail is installed on the support seat; the transport mechanism is used to transport the liquid injection cup along the transport direction of the transport mechanism;

[0009] The cleaning and transporting assembly includes a fixed plate, a transporting and positioning assembly and an upper cleaning mechanism; the fixed plate and the transporting mechanism are connected through a guide column; the upper cleaning mechanism is mounted on the fixed plate; the transporting and positioning assembly is connected to the support seat; the cleaning and transporting assembly is used to clean and transport the liquid injection cup;

[0012] The cache mechanism includes a positioning cylinder; the cache mechanism is installed on the support frame; the cache mechanism is used to store the cleaned liquid injection cup.

[0013] By adopting the above technical solution, the combination of guide rails and servo motors can be used to drive the liquid filling cup to perform long-distance and precise linear movement in a predetermined direction. After the liquid filling cup moves to the predetermined position, the liquid filling cup is positioned by the handling and positioning assembly. Next, the liquid filling cup is lifted by the cylinder, and the various mechanisms and components are moved to align with the liquid filling cup for cleaning. At the same time, the cylinder is used to push the cache mechanism to the lower port of the liquid filling cup, and another cylinder is used to connect the liquid filling cup mouth to pump air and absorb the electrolyte.

The guide rail is a linear guide rail. The support frame includes a support frame 1 and a support frame 2. The support frame is installed with a solenoid valve group.

[0015] By adopting the above technical solution, the module in the transport mechanism grabs the liquid injection cup and uses the servo motor and linear guide to accurately move it to the predetermined position, thereby ensuring the stability of the device operation.

[0019] By adopting the above technical solution, the Y-axis cylinder pushes the cache mechanism to the lower port of the liquid injection cup, and then the Z-axis cylinder docks the liquid injection cup port, and after alignment, negative pressure is introduced to clean the lower cleaning mechanism. After cleaning, it is automatically placed in the cache mechanism. During caching, the liquid injection cup is dried in the air and then taken away by the transport mechanism.

Compared with the existing cleaning device, it has a higher degree of automation, saves labor costs, and the battery production line is more stable.

[0022] 2. The utility model adopts a negative pressure method to further clean the residual electrolyte in the injection cup, and can clean all the electrolyte remaining in the injection cup. At the same time, the injection cup is dried in the provided buffer mechanism, which also improves the cleaning effect of the injection cup. Through this method, the residual electrolyte is prevented from adhering to the cup wall during the injection process, thereby improving the injection accuracy; the residual electrolyte is prevented from crystallizing and clogging the liquid outlet, thereby ensuring the normal outflow of the electrolyte. Through a good cleaning effect, the problem of difficulty in later cleaning and maintenance of the injection cup is avoided. Similarly, when injecting different electrolytes, cross-infection of the electrolyte caused by unclean cleaning of the injection cup is prevented, thereby ensuring the quality and reliability of the product battery.
