Automatic production equipment and technology of power storage battery

Abstract

The invention provides an automatic production equipment and technology of a power storage battery. The cast welding efficiency is greatly improved and the product uniformity is improved through arranged conveyor chain and material carrier loader. Double cast welding platforms and double soldering baths are arranged and a same casting mold mechanism is shared; and the second cast welding platform carries out cast welding operation while the first cast welding platform carries out soldering operation, so that the cast welding efficiency is improved by two sets of cast welding platforms through alternating operation; cast welding defects of false welding, cold soldering and the like caused by lead layer oxidation are prevented through pre-treatment technologies of plate lug polishing, soldering flux brushing, soldering and the like; the cast welding quality is improved; and artificial field operation is not needed. A full-closed space is formed and is connected with a negative pressure ventilation system, so that the harm of lead fume to the body of an operator or the environmental pollution can be greatly reduced.

Description

technical field [0001] The invention relates to the field of power acid storage battery manufacturing, in particular to an automatic production equipment for a power storage battery and a process thereof. Background technique [0002] Lead-acid battery is the only secondary battery that can realize regeneration and recycling among all chemical and physical power sources at present, and has the advantages of mature technology, high cost performance and high discharge rate, so it is widely used in the field of traction power. The assembly process of the power battery is processed and assembled from the plates to form a battery box, usually including positive and negative plates grinding, plates covered with PE separators, positive and negative plates assembled, casting and welding, and other processes. These production processes are generally There are risks of lead exposure and environmental pollution that are harmful to human health, and the assembly quality directly affects...

Problems solved by technology

The assembly process of the power battery is processed and assembled from the plates to form a battery box, usually including positive and negative plates grinding, plates covered with PE separators, positive and negative plates assembled, casting and welding, and other processes. These production processes are generally There are risks of lead exposure and environmental pollution that are harmful to human health, and the assembly quality directly affects the product performance indicators of the battery, such as battery capacity, cycle life, and performance consistency.

[0003] At present, the equipment used for power battery assembly in China is not highly automated, and a large number of manual or semi-automatic production methods are used. The production efficiency is low, and the product quality is greatly affected by human factors. At the same time, environmental protection and occupational health and safety are also difficult to guarantee.
