Vacuum packaging, edge cutting and secondary packaging machine

Abstract

The invention discloses a vacuum packaging, edge cutting and secondary packaging machine which is characterized by comprising a machine case, a rotary disc mechanism, a vacuum packaging mechanism, an edge cutting mechanism (4) and a secondary packaging mechanism. The rotary disc mechanism is arranged inside the machine case, and the vacuum packaging mechanism, the edge cutting mechanism (4) and the secondary packaging mechanism are respectively arranged in the quartering directions of the circumference of the rotary disc mechanism. The rotary disc mechanism comprises a circular rotary disc, a cutting device and a motor, a feeding station and at least two machining stations are evenly arranged on the rotary disc at intervals in the circumferential direction, and a piece to be machined is placed on the feeding station. The vacuum packaging, edge cutting and secondary packaging machine is compact in structure, saves space and enables the structure to be optimized, the production efficiency is improved through reasonable combinations, the production cost is saved, the productivity achieves 4-6PPM, the packaging thickness and non-packaging areas are accurately and stably controlled, the edge cutting accuracy achieves + / -0.2MM, the product pass percent of the whole machine is higher than 99.9%, and the interactive rate is higher than 97%. According to the vacuum packaging, edge cutting and secondary packaging machine, unified standardization is carried out on parts of various structures or with similar functions in a traditional vacuum packaging, edge cutting and secondary packaging machine, the manufacturing efficiency of the machine is greatly improved, and equipment maintenance difficulty is simplified.

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...

[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.
