Heat-conducting rubber sheet fixing structure and end socket

Abstract

The invention discloses a heat-conducting rubber sheet fixing structure, which is used for detachably fixing a conducting rubber sheet on the top of a lower end socket. The heat-conducting rubber sheet fixing structure comprises a locating component and a screw; the lower end socket is correspondingly provided with an accommodating hole and a screw hole; the accommodating hole is formed the top of the lower end socket and extends downwards; the screw hole is formed in side surface of the lower end socket, extends inwards and then is communicated with the accommodating hole; the locating component comprises a fixing part and a hooking part, the fixing part is inserted in the accommodating hole and is provided with a slant facing to the screw hole, one end of the hooking part is fixed at the upper end of the fixing part, the hooking part extends to the heat-conducting rubber sheet, and the other end of the hooking part is bent downwards, is protruded and extends, and then is propped against the heat-conducting rubber sheet; a screw thread is connected with the interior of a screw hole and is propped against the slant. According to the heat-conducting rubber sheet fixing structure, the heat-conducting rubber sheet is in closely contact with the lower end socket, and the heat conductivity is good; the screw is transversely arranged and does not burn an electrode lug, and the heat-conducting rubber sheet is conveniently and quickly replaced. Correspondingly, the invention further discloses an end socket having the heat-conducting rubber sheet.

Description

technical field [0001] The invention relates to the field of lithium battery packaging equipment, in particular to a heat-conducting rubber plate fixing structure and a sealing head with the fixing structure. Background technique [0002] With the wide application and rapid development of various portable electronic devices and electric vehicles, the demand for its power system—chemical power lithium-ion battery is increasing. It is currently the most advanced commercial secondary battery. Lithium-ion batteries are favored for their high capacity, high voltage, high cycle stability, high energy density, and no environmental pollution. They are known as green energy and leading power sources in the 21st century. Among them, flexible packaging lithium-ion batteries have the advantages of high energy density, light weight, many shape changes, and can be made into thin batteries. Therefore, current electronic mobile products basically use flexible packaging lithium-ion batteries...

Problems solved by technology

[0004] At present, the top seal packaging adopts two methods: soft seal and hard seal. In the soft seal method, a silicone plate (or other heat-conducting rubber plate) is fixed on the lower surface of the head of the top seal packaging machine. The fixing method generally adopts screws from the top. However, screwing the silicone plate and fixing it with the lower head has the following disadvantages: 1. During the packaging process, the ear glue is easily burned by the fixing screw cap, which affects the product quality; 2. This fixing method cannot ensure that the silicone plate and the lower seal The surface of the head is in good contact, which affects thermal conductivity, and the risk of bad top-sealing packaging sol is high; third, the replacement of the damaged silicone plate is more cumbersome, and due to the limited distance between the upper and lower heads when replacing, it is necessary to disassemble the head as a whole and then unscrew it Screws take out the silicone plate, which affects production efficiency to a certain extent
