An alkaline battery production line and a production process thereof

Abstract

The invention provides a production line of alkaline battery, comprising a battery steel case hopper, a battery steel case conveying rotary table, a positive electrode ring inserting machine, a sealant coating machine, an isolation tube inserting machine, an electrolyte injecting machine, an electrolyte absorbing machine, a negative electrode material injecting machine and a wire binding machine which are sequentially connected and arranged along the production line direction. The wire binding machine comprises a wire binding head, a limit groove for inserting one end of that open end of the battery steel case is arranged on the surface of the binding head, and the opening end of the battery steel case is inserted into the limit groove when the binding head is in operation, so that the battery steel case is fixed on the binding head, the binding wheels on both sides of the binding head squeeze the battery steel case rotating at a high speed inwardly, and an annular groove is formed onthe outer wall of the battery steel case to realize binding. The production line of the alkaline battery thoroughly solves the problem that a high-level positive electrode ring broken ring occurs whenthe filling height of the positive electrode ring is increased, improves the filling rate of the active material in the battery, and further improves the comprehensive electric performance of the alkaline battery.

Description

Technical field [0001] The invention relates to the field of battery manufacturing, in particular to an alkaline battery production line and production process. Background technique [0002] With the rapid advancement of various technologies in recent years, electrical appliances have put forward higher and higher requirements for the performance of alkaline batteries. Improving the overall electrical performance of alkaline batteries has become the research direction of various battery manufacturers. At present, the following methods are mainly used to improve the overall electrical performance of alkaline batteries: (1) Increase the amount of active material (ie "positive ring") inside the battery; (2) Optimize the formulation of the active material inside the battery. Common ways to increase the amount of active material in the battery include increasing the outer diameter of the battery and increasing the filler height of the positive electrode ring. [0003] Because the gene...

Problems solved by technology

[0006] When increasing the filling height of the positive electrode ring 110 (referred to as "high filling" in the industry) to increase the filling amount of the active material inside the battery, after the battery steel case 100 is filled with the positive electrode ring 110 by the positive electrode ring inserting machine 30', the Next, the outer side of the battery steel case 100 must be "tied" by the wire binding machine 80', and the "wire binding" operation will inevitably lead to deformation of the battery steel case 100, and the deformation of the battery steel case 100 will easily cause a high positive electrode. "Broken ring" problem occurred on ring 110

And these broken positive electrode ring materials will be poured out from the inside of the battery steel case together with the iron pins produced in the ring binding process when they are turned over and transported to the runway 00', resulting in a waste of positive electrode ring materials. At the same time, it is impossible to achieve The effect of improving the overall electrical performance of alkaline batteries
