Problems solved by technology

[0004] When the above-mentioned device is used for liquid injection, due to strong sealing performance requirements, a little carelessness will cause inaccurate liquid injection volume, and at the same time, there is a large vacuum space in the device, which is not conducive to improving the accuracy of liquid injection volume
In addition, the liquid injection of the device is divided into multiple injections, and the required electrolyte is not injected into the battery at one time, which is prone to suck back
The structure of the device is complicated, the operation is cumbersome, the liquid injection efficiency is not high, and the maintenance rate of the equipment is high

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The battery liquid injection machine of the present invention has a vacuum mechanism and a liquid injection mechanism, wherein the vacuum mechanism has a vacuum suction needle, and the liquid injection mechanism has a liquid injection needle. see figure 2 As shown, it is a preferred embodiment of the battery liquid injection needle in the present invention. The battery liquid injection needle has a needle head 20, and the needle head 20 is provided with a substantially funnel-shaped inner cavity. A hollow tubular vacuum suction needle 21 is inserted into the inner cavity of the needle 20, and tightly fits with the inner cavity neck of the needle 20, and a sealing ring 23 is arranged on the inner cavity neck in contact with it. A steel ball 22 is arranged in the inner cavity of the needle 20, the diameter of which is larger th...

Abstract

This is a cell needle and the injection device. The needle is of an inner cavum which is sealed in a vacuum needle and steel ball matching to the end of the needle. There is a concave part on the side wall of the cavum, and an electromagnet is installed to the position of the concave part.

Description

technical field [0001] The invention relates to battery processing equipment, in particular to a battery liquid injection needle and a battery liquid injection device using the liquid injection needle. Background technique [0002] As a new type of green and environmentally friendly battery, liquid lithium-ion secondary battery represents the advanced level of current chemical power supply development. Due to the advantages of high specific energy, long cycle life, no memory effect, safety and pollution-free, and fast charging and discharging, lithium-ion batteries have been widely used in electronic devices such as cameras and notebook computers, and are gradually being used in electric bicycles and electric vehicles. and other fields to expand the scope of application. [0003] Researchers from various countries have not only conducted a lot of research on the positive and negative electrode materials of the battery, the electrolyte and the structure of the battery, but a...
