Soft package battery packaging equipment

Abstract

The invention discloses soft package battery packaging equipment, which comprises a machine and a seal mechanism arranged on the machine, wherein the seal mechanism comprises a seal head assembly, a power assembly connected with the seal head assembly for driving the seal head assembly to move, a control assembly connected with the seal head assembly and the power assembly separately and a refrigerating mechanism; the seal head assembly comprises an upper seal head and a lower seal head which are oppositely arranged up and down; the refrigerating mechanism comprises a refrigerating assembly and a refrigerating conduction plate; the refrigerating assembly is arranged at the upper part of the machine; the refrigerating conduction plate is arranged at the upper part of the refrigerating assembly and is used for placing a soft package battery; and the refrigerating conduction plate is located on the side between the upper seal head and the lower seal head, so that an edge pre-sealing side of an air bag of the soft package battery on the refrigerating conduction plate is located between the upper seal head and the lower seal head. According to the soft package battery packaging equipment, the thermal radiation effect can be effectively reduced and an inner layer of the air bag is prevented from being melted, thereby achieving the targets of saving raw materials and controlling the product quality.

Description

technical field [0001] The invention relates to the field of soft pack battery production equipment, in particular to soft pack battery packaging equipment. Background technique [0002] Flexible packaging lithium-ion batteries have attracted more and more attention from manufacturers because of their high energy density and good cycle life. During the formation process of flexible packaging lithium-ion batteries, the electrolyte will react with the active material at the interface, forming a thin film on the surface of the active material, that is, the SEI film. During the formation of the SEI film, a certain amount of gas is generated. In order to eliminate these gases, an air bag 402 is generally reserved on the side of the battery body 401, and the height of the air bag 402 is the same as that of the battery body 401 (such as figure 1 shown), the width of the air bag 402 is generally 40-80mm, figure 2 The width of the middle air bag 402 is 50 mm. After the battery b...
