Top seal head of soft package battery

The utility model discloses a top seal head of a soft package battery. The top seal head comprises an upper seal head and a lower seal head, a lower heating protrusion is arranged on the upper side of the lower sealing head, two containing grooves protruding forwards are formed in the middle of the lower heating protrusion and arranged in a spaced mode, an upper heating protrusion is arranged on the lower side of the upper sealing head, and the upper heating protrusion and the lower heating protrusion are arranged in a mirror symmetry mode. The top seal head can be used for heat-sealing the soft package battery with a bulge structure at the front end, and is formed by heat-sealing at one time, so that the packaging efficiency of the soft package battery is improved, and the production cost of the soft package battery is reduced. 本实用新型公开了一种软包电池的顶封封头，包括上封头和下封头；下封头的上侧设有下加热凸起，下加热凸起的中间位置形成有两个向前凸的容纳槽，且两个容纳槽之间间隔设置，上封头的下侧设有上加热凸起，上加热凸起与下加热凸起镜像对称设置。该顶封封头能够热封前端具有凸起结构的软包电池，且一次热封成型，提高了软包电池的封装效率，降低了软包电池的生产成本。
