Automatic secondary-packaging molding production line

Abstract

The invention discloses an automatic secondary-packaging molding production line. The production line comprises a feeding unit, a packaging unit, a molding unit and a discharging unit, wherein the feeding unit comprises a feeding pull band; the packaging unit comprises a primary-packaging station and a primary-cutting station; the primary-packaging station is arranged close to the primary-packaging correction station; an upper packaging cavity, a low packaging cavity and a movable cavity are formed in the primary-packaging station; the primary-cutting station is provided with a primary-cutting mechanism for cutting sealing edges of cells; the molding unit comprises a cell transfer mechanism, and a fine packaging mechanism, a rolling wheel edge-folding mechanism, an adhesive dispensing mechanism, a thermoprint edge-folding mechanism, and a second weighing station arranged on the two sides of the cell transfer mechanism in sequence; and the discharging unit comprises a discharging pull band. According to the automatic secondary-packaging molding production line, the feeding unit, the packaging unit, the molding unit and the discharging unit are integrated on one equipment, so that the fully automatic production of a softly-packaged lithium battery from feeding to discharging can be realized; and therefore, the production efficiency of the lithium battery is improved, the productivity is improved, the production cost is lowered, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the technology in the field of lithium battery production equipment, in particular to an automatic two-sealing molding production line for the production of soft pack power lithium batteries. Background technique [0002] Flexible packaging lithium batteries have the advantages of high voltage, high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices, but also widely used in large and medium-sized electric devices such as electric vehicles, electric bicycles, and electric tools. . The production process of flexible packaging lithium batteries includes multiple processes such as vacuum packaging, air bag pre-cutting, secondary fine sealing, fine trimming, folding, dispensing, ironing, weighing and scanning codes, and NG sorting. Fully automated production equipment with multiple processes has appeared. In order to improve the production efficiency of lithium bat...

Problems solved by technology

The production process of flexible packaging lithium batteries includes multiple processes such as vacuum packaging, air bag pre-cutting, secondary fine sealing, fine trimming, folding, dispensing, ironing, weighing and scanning codes, and NG sorting. Fully automated production equipment with multiple processes has appeared. In order to improve the production efficiency of lithium batteries, a turntable double-sided heating vacuum packaging machine has appeared. High, in actual production it is often necessary for one person to operate two sets of equipment at the same time, resulting in a large amount of personnel input, resulting in high production costs, and also requires operators to have a certain degree of proficiency, which is prone to safety accidents when the operation is improper
