A vacuum packaging, trimming and secondary packaging machine

Abstract

The invention discloses a machine for vacuum encapsulation, edge trimming and secondary encapsulation, which is characterized in that it comprises a chassis, a turntable mechanism, a vacuum encapsulation mechanism, an edge trimming mechanism and a secondary encapsulation mechanism, wherein a turntable mechanism is arranged inside the chassis , vacuum encapsulation mechanism, trimming mechanism 4 and secondary encapsulation mechanism, are respectively arranged along the circumference four equal division directions of turntable mechanism; Described turntable mechanism comprises circular turntable, divider and motor, and the turntable is uniform along the circumferential direction. One feeding station and at least two processing stations are arranged at intervals, and the workpiece to be processed is placed on the feeding station. The present invention has a compact structure, saves space, optimizes the mechanism, and reasonable combination improves production efficiency, saves production costs, production capacity reaches 4-6PPM, seal thickness and unsealed area control is accurate and stable, and edge trimming accuracy reaches plus or minus 0.2 MM, the qualified rate of the whole machine is higher than 99.9%, and the grafting rate is higher than 97%. Machine manufacturing efficiency simplifies the difficulty of equipment maintenance.

Description

technical field [0001] The invention relates to lithium battery processing equipment, in particular to a vacuum packaging, trimming and secondary packaging machine. Background technique [0002] Lithium battery is a kind of electrical energy storage device widely used in the market at present, especially the flexible package lithium battery is widely used as the energy supply device of electronic products such as mobile phone due to its unique advantages. [0003] The production of lithium batteries involves dozens of processes, and the smooth completion of each process requires corresponding equipment. The entire production process is long, requires a lot of equipment, and takes up a lot of space. In the field of soft-pack lithium battery production, it is necessary to The battery air bag is packaged, and then the edge is trimmed after packaging, and then the packaging process is precisely positioned. At present, the degree of automation of battery manufacturers is low. Man...

Problems solved by technology

[0003] The production of lithium batteries involves dozens of processes, and the smooth completion of each process requires corresponding equipment. The entire production process is long, requires a lot of equipment, and takes up a lot of space. In the field of soft-pack lithium battery production, it is necessary to The battery air bag is packaged, and then the edge is trimmed after packaging, and then the packaging process is precisely positioned. At present, the degree of automation of battery manufacturers is low. Many of the above-mentioned processes are completed by manual and semi-automatic equipment with a single function. The demand is large, the production efficiency is low, the product quality is unstable, and the product scrap rate is high. Therefore, an equipment with high degree of automation, high precision and good stability is needed in the field of soft package lithium battery production.

[0004] At present, the methods used by manufacturers for the three processes of vacuum packaging, trimming and secondary packaging are to use separate sequential equipment to complete them, such as the "servo double-sided heating vacuum packaging machine" disclosed in the Chinese invention patent application number 201110101111.8, The Chinese invention patent with the authorized announcement number CN 102152943 B discloses "Circular transmission mechanism and fully automatic cell pumping liquid sealing forming packaging machine, and the Chinese utility model patent with the authorized announcement number CN 203127242 U discloses "a single trimming device ", the above-mentioned equipment completes a process alone, with limited functions, complex structure, and great difficulty in manufacturing and maintaining the equipment.
