Servo double-surface heating vacuum packaging machine

Abstract

The invention discloses a servo double-surface heating vacuum packaging machine and belongs to liquid extraction seal secondary forming and packaging equipment of flexible packaged lithium batteries. The servo double-surface heating vacuum packaging machine comprises a double-station turntable feeding device driven by a cam partitioning device, a packaging mechanism with an up-and-down packaging device, and an electric control system, wherein the up-and-down packaging device comprises an upper cavity main body and a lower cavity main body; the opening directions of the upper cavity main body and the lower cavity main body are opposite to each other; the upper cavity main body and the lower cavity main body can clamp the turntable to form a sealed cavity body; a pressing board, an upper sealing head and a bayonet are arranged in the upper cavity main body; a lower sealing head and an aspirating hole are arranged in the lower cavity main body; the aspirating hole is communicated with an external vacuum source; the upper sealing head corresponds to the lower sealing head; and a heating body is arranged inside the servo double-surface heating vacuum packaging machine. The servo double-surface heating vacuum packaging machine has a compact structure and high efficiency; the electric core packaging quality is stable and the cost is low; vacuum liquid extraction can be realized; and pollution of the electrolyte to the equipment can be reduced to minimum.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a servo double-sided heating vacuum packaging machine for performing liquid pumping, sealing and secondary molding packaging on soft-pack lithium batteries. Background technique [0002] At present, the outer casing of the battery is generally divided into a metal casing and a non-metal casing. In comparison, a battery prepared using a non-metal casing can significantly reduce the manufacturing cost of the battery and increase the energy density and power density of the battery. However, the flexible packaging process of non-metallic casings has very high requirements on packaging methods and precision, otherwise it is easy to cause bad situations such as battery casing rupture, liquid leakage, flatulence, and even explosion, resulting in a low yield of battery packaging; Most of them have adopted automatic or semi-automatic production lines, but semi-automatic production ...

Problems solved by technology

However, the flexible packaging process of non-metallic casings requires very high packaging methods and precision, otherwise it is easy to cause bad situations such as battery casing rupture, liquid leakage, flatulence, and even explosion, resulting in a low yield of battery packaging; Most of them have adopted automatic or semi-automatic production lines, but semi-automatic production lines have poor quality stability and limited production efficiency due to manual operation; while fully automatic production lines are relatively large-scale, with high equipment costs, and are not suitable for flexible production in small batches; Therefore, the market needs a battery packaging equipment with stable production quality, high efficiency and low cost
