Slot-in device and method for automatic short-circuit detection after cast welding of storage battery

Abstract

The invention discloses a slot-in device and method for automatic short-circuit detection after cast welding of a storage battery. The slot-in device comprises a turnover device, a 90-degree rotation device, a battery box moving device, a slot-in press mounting device, a slag removal device, a short-circuit test device, a sorting device and a machine frame. According to the invention, automation of procedures of a battery box after cast welding is realized through the turnover, 90-degree rotation, secondary slot-in press mounting, slag removal, short-circuit testing and sorting procedures, so that the problems of high manpower cost and low efficiency, which are caused by manual press mounting, slag removal and short-circuit testing after cast welding of the storage battery, are solved, human resources are saved and the production efficiency and the quality of the storage battery are both improved.

Description

technical field [0001] The invention relates to the technical field of storage battery manufacturing, in particular to a slotting device and method for automatic short circuit detection after casting and welding of storage batteries. Background technique [0002] In recent years, with the increasing calls for green, environmental protection and energy saving, hybrid electric vehicles have gradually become the mainstream products in the automobile market, and this performance index of batteries is becoming more and more important. Lead-acid batteries have become the main candidate power sources for hybrid electric vehicles due to their low price, stable voltage and high safety performance. In the production process of lead-acid batteries, there are several processes between the casting and welding process and the battery capping process: press into the tank, slag removal, short-circuit test, etc. At present, the domestic mainly relies on manual operation, which is inefficient...

AI Technical Summary

Problems solved by technology

In the production process of lead-acid batteries, there are several processes between the casting and welding process and the battery capping process: press into the tank, slag removal, short-circuit test, etc. At present, the domestic mainly relies on manual operation, which is inefficient, resulting in the entire The production cycle is lengthened and the cost increases

In the short-circuit test process, it often happens that the negative high-voltage fault is not detected, which leads to the failure of the unqualified short-circuit battery to enter the next process, resulting in the production of unqualified battery products

In addition, in the existing casting welding process, the half-packed pole group is generally pressed into the bottom of the box after casting and welding. Compared with the half-packed state before casting and welding, this process makes it inconvenient to find defects during manual visual inspection. The battery pack has been pressed into the bottom of the box. For the unqualified batteries detected, the battery pack needs to be pulled out from the bottom of the box for maintenance, which makes subsequent maintenance more difficult.

[0003] After searching the literature of the prior art, it is found that the following deficiencies are found: 1. There is no fully automated equipment connecting the casting and welding process and the battery capping process; 2. The short circuit detection process requires manual testing, which is not efficient and is likely to cause False detection; 3. In the existing casting and welding process, the half-packed pole group is cast and welded and then pressed to the bottom of the box, which is inconvenient for subsequent testing and maintenance of unqualified products
