Ultra-thin soft pack battery sealing machine and sealing method thereof

Abstract

The invention discloses an ultra-thin soft pack battery sealing machine, including a rack, an upper support plate, a guide slidinge plate and a lower support plate are sequentially arranged on the rack from the top to the bottom, the guide sliding plate is provided with a plurality of guide holes, the upper support plate is provided with a driving cylinder, the piston rod of the driving cylinder is connected with an upper pressure bearing plate, the upper pressure bearing plate is connected with a plurality of pressure bearing rods, the pressure bearing rods are connected with the upper head structure through the guide hole, and the lower support plate is provided with a lower head structure matched with the upper head structure; the upper head structure comprises an upper cavity fixedly connected with the bottom end of the pressure bearing rod, an upper heating plate is fixedly connected with the upper cavity, and a plate-shaped upper seal plate is fixedly connected with the bottom ofthe upper heating plate. The lower head structure comprises a lower cavity which is sealingly matched with the upper cavity, and the lower cavity is fixedly connected with a lower seal plate which isin the shape of a plate; the bottom surface of the upper seal plate or the top surface of the lower seal plate is fixedly provided with a silica gel layer. The invention is simple and feasible in operation and greatly improves sealing efficiency and product quality.

Description

technical field [0001] The invention relates to a soft pack battery sealing technology, in particular to an ultra-thin soft pack battery sealing machine and a sealing method thereof. Background technique [0002] Ultra-thin soft-pack batteries are widely used in smart cards due to their thin thickness (<0.6mm), such as financial cards, logistics positioning cards, etc. At present, the packaging process of soft-pack batteries is a three-time sealing molding process, namely: top sealing (first sealing) , side sealing (second sealing), vacuum sealing (third sealing), for ultra-thin pouch batteries, the aluminum-plastic film generally does not need to be punched, but the existing technology has very high requirements for the positioning of the battery in the sealing process , so the equipment requirements are high, the production efficiency is low, and it is easy to produce defective batteries, which affects product quality. Contents of the invention [0003] The purpose o...
