Soft pack battery packaging equipment

Abstract

The invention discloses a soft pack battery packaging device. The equipment includes a machine table and a sealing mechanism arranged on the machine table; the sealing mechanism includes a head assembly, a power assembly connected to the head assembly for driving the movement of the head assembly, and a control unit connected to the head assembly and the power assembly respectively. assembly; the head assembly includes an upper head and a lower head arranged up and down oppositely; it also includes a refrigeration mechanism; the refrigeration mechanism includes a refrigeration assembly and a refrigeration conduction plate; the refrigeration assembly is arranged above the machine; the refrigeration conduction plate is arranged above the refrigeration assembly, Used to place pouch batteries; the cooling conduction plate is located on the side between the upper and lower seals, so that the pre-sealed edge of the air bag edge of the pouch battery placed on the cooling conduction plate is located between the upper and lower seals between the heads. The pouch battery packaging equipment can effectively reduce the heat radiation effect and prevent the inner layer of the air bag from melting, so as to save raw materials and control 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 50mm. After the battery bo...
