Background

When the lithium ion battery works normally, an electronic passage is formed by a negative end led out by a negative current collector and a positive end led out by a positive current collector and an external circuit, an ion passage is formed by electrolyte and lithium ions in positive and negative active substances, and the electronic passage and the ion passage form a loop together so as to achieve the aim of normal work. With the increasing demand of lithium ion batteries, people have higher and higher performance requirements in all aspects, especially the requirement on the cycle performance of the batteries, the injection amount of the batteries is an important parameter for ensuring the cycle of the batteries, and the cycle decay is too fast due to the too small injection amount, so that the service life of the batteries is too fast. However, the excessive liquid injection amount can cause the battery to expand and damage the overall structure of the battery.

When traditional lithium cell annotates liquid production, generally use artifical notes liquid mode, carry out the liquid processing of annotating of one-to-one, annotate the liquid precision low, production efficiency is low, the security is poor.

Although the prior art also has the automatic electrolyte injection machine of a forward injection type and a vacuum reverse-suction type, the vacuum reverse-suction type has higher requirement on the sealing performance of the equipment pipeline and strict sealing conditions; and the forward liquid injection mode also has the technical problem of high liquid injection precision control difficulty.

No matter what kind of liquid mode is adopted at present, all arrange a plurality of electric cores that need annotate liquid in the turnover basket in, annotate the liquid pipeline and pass through the position of sealing of reserving and accomplish it and annotate liquid, but the operation process has avoided the splash of electrolyte, and when the aluminium-plastic packaging film of electric core surface was spattered to electrolyte, the damaged problem of packaging film surface corrosion very easily appears in the later stage.

The width of the anti-pollution end is consistent with the width between the adjacent electric cores.

The anti-pollution strips are consistent with the partition plates in quantity, and the height of each partition plate is smaller than that of each battery cell.

A gap is formed between the anti-pollution strips, and an aluminum plastic packaging film above the battery cell is arranged in the gap.

Still be equipped with the positioning and moving device on the workstation, the positioning and moving device includes the location cylinder, and the piston rod of location cylinder links to each other with annotating the anti-pollution board of liquid.

The workbench is provided with a groove, and the cell turnover basket is arranged in the groove.

The utility model has the advantages that: through the long and thin anti-pollution strip of front end that sets up, be convenient for the location insert between the electric core, the rectangular shape width of rear end is for the gap width between the turnover basket, inserts the anti-splash device before annotating the liquid, can not hinder and reach electric core plastic-aluminum membrane top layer after the electrolyte spill, can effectively prevent that the packaging film from corroding.
