Description

Technical Field

[0001] The invention relates to a multi-head negative pressure cleaning device with horizontal poles on both sides of a square lithium battery, belonging to the field of battery manufacturing. Background Art

[0002] As a new generation of power and energy storage power source, lithium battery has superior performance, reliable process and wide application. During the negative pressure formation of lithium battery, the negative pressure formation equipment needs to adjust the air pressure inside the battery through the pressure control system, and extract the gas generated during the battery formation process from the battery injection port through the negative pressure vacuum system. In this process, part of the electrolyte in the lithium battery will be pumped into a temporary container (such as a collection cup) along with the above gas, and then the positive pressure dry gas system will be used to fill the container with dry gas to re-inject the electrolyte into the battery. Since lithium batteries are generally produced in a high temperature and low dew point environment, the electrolyte is easy to crystallize and precipitate in the negative pressure vacuum system of the negative pressure formation equipment, resulting in blockage of the exhaust pipe. If it cannot be discovered and handled in time, the gas generated during the battery formation process will be retained in the lithium battery, causing the battery shell to swell, be scrapped, and even cause battery explosion, which will cause great harm and loss.

[0048] In some embodiments of the present invention, the cleaning pump 22 is a double-inlet and double-outlet circulating pump, the two water inlets of the cleaning pump 22 are connected to the clean water chamber 202 of the cleaning circulating water tank 22 through the first cleaning pipe 25, and the two water outlets of the cleaning pump 22 are connected to the two cleaning holes 211 of the cleaning reflux device 24 through the second cleaning pipe 26. The cleaning circulating water tank 21 realizes the storage and recycling of water, and the cleaning liquid provides pressure through the cleaning pump 22 to complete the cleaning of the negative pressure suction nozzle and the collection cup of the negative pressure formation equipment. Two return holes 212 are provided on the cleaning reflux device 24, and the two return holes 212 are connected to the water inlet end of a ball valve 23 through two first return pipes 27, and the water outlet end of the ball valve 23 is connected to the return chamber 203 of the cleaning circulating water tank 21 through the second return pipe 28.

The cleaning liquid mixed with crystal precipitation in the return water chamber 203 can be intercepted in the return water chamber 203 to prevent these crystals from flowing back into the clean water chamber, thereby realizing the recycling of the cleaning liquid in the cleaning circulation water tank 21. When in use, the return water chamber 203 can be cleaned regularly or the cleaning liquid in the cleaning circulation water tank 21 can be replaced.

The power control mechanism receives the host computer instructions through the signal interface to realize automatic control of the negative pressure cleaning equipment, and controls and detects the entire equipment. When a problem occurs, it is fed back to the host computer to quickly find the problem and deal with it in time.
