Linear production line and production process of power tabs

Abstract

The invention relates to a linear production line of power tabs. A discharging deviation rectifying device, a leveling guide preheating device, a glue pulling and sticking device, a hot pressing device, at least one inner heating device, a high-frequency device, a cold pressing device, a shaping device, a material pulling device, a material pressing device, a cutting device and a chamfering device are sequentially arranged on a main mounting plate from front to back; and the leveling guide preheating device, the glue pulling and pasting device, the hot pressing device, the inner heating device, the high-frequency device, the cold pressing device, the shaping device, the material pulling device, the material pressing device, the cutting device and the chamfering device are located on the same straight line. According to the invention, continuous automatic production can be realized, the production precision is high, the relative positions of the tab glue and the metal belt are effectively controlled, and the precision is controlled within + / -0.1 mm; the straightness of the metal belt is always kept, the material belt is prevented from deviating, and the machining precision is improved; and glue feeding and gluing are stable, and the adhesion of the tab glue and the metal belt is improved through hot pressing, at least one time of internal heating and high-frequency heating in sequence.

Description

technical field [0001] The invention relates to the technical field of tab processing for soft-pack lithium batteries, in particular to a linear production line and a production process for power tabs. Background technique [0002] In recent years, electric vehicles have developed rapidly in my country. Electric vehicles need power batteries to provide power, and power tabs are the core components of power batteries. The market's demand for power tabs is also very large. Ordinary pole earphones can no longer meet the production requirements. The conditions of the power tab require that the quality of the power tab is very high, and it is a safety lock for the pouch battery. Existing power tab equipment is generally transformed from the original digital tab equipment. Often only the external dimensions of the equipment are changed, and the equipment is not improved according to the quality requirements of the power tab and digital tab, resulting in poor quality of the power ta...

Problems solved by technology

Existing power tab equipment is generally transformed from the original digital tab equipment. Often only the external dimensions of the equipment are changed, and the equipment is not improved according to the quality requirements of the power tab and digital tab, resulting in poor quality of the power tab. The pass rate is low, such as poor adhesion of parts, wrong glue, dimensional instability, etc., poor stability, resulting in increased production costs; some processes have not yet achieved automated production, low production efficiency, and high production costs
