Description

technical field [0001] The invention relates to the field of storage battery production equipment, in particular to an automatic acid filling machine used for acid filling of storage batteries. Background technique [0002] In the battery production process, it is necessary to add acid to each cell. Due to the small volume and the presence of gas in the closed cell, direct perfusion is time-consuming and difficult to achieve. At present, the vacuum automatic acid feeding machine is used in industrial production. First, the battery is placed on the tray, and the conveyor belt conveys the tray and the battery in the tray, and then the battery is transferred from the conveyor belt to the acid filling worker aligned up and down with the acid injection nozzle. Then, the acid filling station is pushed upward until it is connected with the acid injection nozzle, and then a negative pressure is formed inside the battery after vacuuming, and then the acid is poured into the battery ...

AI Technical Summary

Problems solved by technology

At present, the automatic acid filling machines on the market have the following defects: 1. When vacuuming, the vacuum state inside the transition bottle and the battery cannot be accurately controlled, and the tightness of the transition bottle cannot be monitored in real time; 2. When injecting acid, If the acid injection nozzle is blocked, the staff cannot find it in time, so that the defective battery cannot be found in time, and it is easy to pump the acid into the vacuum barrel to corrode the vacuum barrel when vacuuming; 3. Battery During the acid filling, two transfers and one lifting are required, which not only reduces the efficiency of acid injection, but also the acid liquid of the battery will shake during multiple actions, and the acid liquid is prone to acid overflow when it shakes. This leads to a reduction in the amount of acid in the battery, making the battery unqualified
