Sealing device for steel ball conveying and press-in of lithium ionic cell

Abstract

The invention relates to a steel ball transferring pressing seal device for lithium battery, which includes an upper model board and a lower model board which are oppositely disposed and between which a sliding board provided with ball transferring hole is arranged in parallel; the upper model board is provided a ball storage cavity for transferring steel ball which is aslant opened from up to down; one side of the bottom face of the lower model board is provided with a cavity for battery positioning and opened upwards, opposite to which a steel ball inducing hole which vertically drills through the lower board; and opposite to the steel ball inducing hole of the lower board, a pin hammer inducing hole is vertically arranged on the upper model board in coaxial, within which a pin hammer is disposed. In application, the steel ball aslant slides form the ball storage cavity into the transferring hole of the sliding board, and the sliding board drives the steel ball forward to input the same into the steel inducing hole, and then, the steel ball is pressed into a battery injection port by the pin hammer vertical motion via the steel ball inducing hole thereby completing the seal for battery cover. The device is not only suitable for the seal in normal condition, but is also suitable for vacuum seal; and it can automatically transfer and supply the steel balls one by one, accurately position, and has remarkable effect.

Description

technical field [0001] The invention relates to a lithium-ion battery sealing device, in particular to a sealing device used for conveying and pressing lithium-ion battery steel balls. Background technique [0002] At present, lithium batteries are widely used in the power supply of electronic devices such as mobile phones, notebook computers, electric bicycles, electric vehicles, aerospace, MP3, earphones, etc. All countries in the world are using lithium-ion secondary batteries in the field of communications, portable electronic products, electric vehicles, etc. The applications in automobiles and aerospace have shown great concern, and the performance of lithium-ion secondary batteries, especially the manufacturing process, has been continuously explored and improved. [0003] In the production process of lithium-ion batteries, according to the technical requirements, the sealing process is the last key process of battery assembly. At present, Chinese battery manufacture...

AI Technical Summary

Problems solved by technology

However, since the diameter of the steel balls is only about 1.3mm, it is difficult to supply one by one, and the sealing ball must ensure its process accuracy; therefore, the current commonly used method is to use tweezers to pick up a single steel ball and put it on the battery liquid injection port. Then manually smash it in with a small hammer

In this way, due to the low success rate of clamping steel balls during the operation process and the uneven strength of manual smashing of the balls, it will also cause low production efficiency and poor appearance, especially the resulting battery leakage phenomenon remains high, resulting in The quality of the finished battery is problematic, and the operation is backward, which cannot reduce the production cost
