Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery liquid injection, in particular to a battery liquid injection system. Background Art
[0002] The filling machine is a filling device used in the production process of square aluminum shell lithium batteries. The lithium battery filling machine is mainly composed of an electrolyte storage tank, a pump, a conveyor belt, a positioning device and a control panel. When working, the battery is first placed on the conveyor belt, and then transferred to the positioning device. The positioning device positions the battery in the correct position. Subsequently, the pump extracts the electrolyte from the storage tank and delivers it to the battery through the delivery pipe. When the battery reaches the predetermined capacity, the pump automatically stops working and the conveyor belt transfers the battery out.
[0003] However, when the filling machine is filling the square aluminum shell lithium battery, the arrangement and layout of the positive plate, negative plate, diaphragm and other components inside the battery affect the flow and penetration of the electrolyte, causing the electrolyte to accumulate near the filling port. Especially after the filling is completed, due to the surface tension of the liquid and the action of gravity, the electrolyte is likely to remain on the outside of the filling port and its surrounding area. There is electrolyte residue around the filling port. When weighing, this part of the residual electrolyte will be included in the total weight, making the actual amount of electrolyte injected into the battery less than expected. The staff will subsequently need to clean the electrolyte at the filling port and re-weigh it, and perform a second filling, which increases production costs and working hours.
[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a battery injection system to solve the above problems. Utility Model Content

[0010] The preferred technical solution is: the blowing mechanism is composed of an air pump and a blowing pipe, one end of the blowing pipe is connected to the air outlet end of the air pump, and the other end of the blowing pipe is arranged toward the conveying line.

The second telescopic cylinder is fixedly arranged on the side of the conveyor line, and the second material blocking rod is fixedly arranged at the telescopic end of the second telescopic rod and is arranged perpendicular to the conveying direction of the conveyor line.
