A lithium battery hand-held steel ball sealing tool

Abstract

The invention discloses a lithium battery hand-held steel ball sealing tool, which comprises an outer casing, a steel ball and a liquid-injection joint arranged at the bottom end of the outer casing. A cylinder and a steel ball funnel are vertically and parallelly arranged inside the outer casing. The end is connected with a rivet head, and the bottom end of the rivet head is located just above the liquid injection joint; the inner shell located just below the rivet head and the steel ball funnel is provided with a center point along the bottom end of the rivet head and the steel ball funnel An L-shaped telescopic plate for telescopic movement of the connecting line; through holes matched with steel balls are opened on the horizontal section of the L-shaped telescopic plate, and the vertical section of the L-shaped telescopic plate is located outside the outer casing, and is connected to the outer casing through a spring outer wall connection. The steel ball sealing tool of the invention is simple in structure and convenient in operation, and can avoid the misalignment of the steel ball sealing through manual observation, which not only improves the production efficiency, but also greatly improves the production quality.

Description

technical field [0001] The invention belongs to the technical field of lithium battery production, and in particular relates to a hand-held steel ball sealing tool for lithium batteries. Background technique [0002] Formation refers to an operation of pre-charging and activating the battery when the battery has no capacity, also called pre-charging, (electrical) activation or (electrical) activation, in order to make the battery have stable charge-discharge characteristics pre-steps. Formation is a key process in battery manufacturing, that is, the process of converting the plates into positive and negative plates with electrochemical characteristics by using chemical and electrochemical reactions. The quality of the conversion process will directly affect the performance of the battery. Aluminum shell batteries usually adopt open formation, because gas will be produced during the formation process, and the opening formation is to let the gas produced by the formation be d...

Problems solved by technology

However, due to the small size of the steel ball opening, it is easy to seal the ball incorrectly when the machine is used to seal the steel ball, resulting in a high scrap rate of 2 / 1000; and when the steel ball is sealed manually, one hand holds the suction pen and the other holds the knocking object, and the single cycle After loading and unloading, although it is not easy to seal the deviation and the operation is simple, the efficiency is low, and it is easily limited by the vacuum. The electrolyte is easy to crystallize, and the hole of the tool is blocked, and the frequency is too high for 0.5 hours / time, so it takes It takes a lot of time to check the location of the blockage, disassemble, clean, and reassemble, and the efficiency is very low
