High-efficiency hot melting riveting device for lithium ion power battery pack

Abstract

The invention relates to the technical field of battery hot melting connection, and discloses a high-efficiency hot melting riveting device for a lithium ion power battery pack. The device comprises an upper mold plate, wherein guide columns are arranged on the four sides of the bottom end of the upper mold plate, springs are arranged on the outer walls of the guide columns, the lower portions of the springs are fixed to a push plate fixing seat, the guide columns penetrate through the push plate fixing seat and extends to the lower portion, a lower mold plate is arranged below the middle of the upper mold plate, a graded preheating hot melting mechanism is arranged at the bottom end of the lower mold plate, and the two sides of the graded preheating hot melting mechanism extend to the bottom end of the push plate fixing seat. According to the device, temperature control, graded preheating, heating baking and active heat dissipation cooling are achieved through the arranged graded preheating hot melting mechanism, in this way, during hot melting riveting forming, the temperature of all hot melting points can be rapidly reduced so that plastic can be solidified, it is avoided that a plastic hot melting column in a semi-melting state is directly separated from a hot melting head, and the problems of deformation of the hot melting point, strain, insufficiency, no wrapping force and insufficient riveting strength are solved.

Description

Technical field [0001] The present invention relates to the technical field of battery thermal fusion connection, and in particular, it relates to a highly efficient hot-fuser riveting device for a lithium ion power battery. Background technique [0002] Small home appliances, toy products generally apply plastic riveting process to fix some static use of small buttons, PCB boards, and most of them are hot melt rivets of single hot melt or less than 10 points. [0003] The hot melt device is heated, and the plastic hot melting column is continuously held in a high temperature. When the hot melt is completed, the plastic is still in a half-melted high temperature state, which causes hot melt surface when separated from the plastic hot melt column. Deformation, poor burning, and hot melt packaging force is small, and cannot meet the power battery assembly of the vibration conditions and the structural strength requirements of the plastic fixed structure.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-efficiency hot-melt riveting device for lithium-ion power battery packs, which can realize temperature control, graded preheating, heating, baking and cooling through the set grading preheating hot-melt mechanism, so that it can be graded during hot-melt riveting Preheating the plastic hot-melt column and quickly lowering the temperature of each hot-melt point to solidify the plastic prevents the plastic hot-melt column from being directly separated from the hot-melt head when it is in a semi-molten state. In the semi-melted high-temperature state, when it is separated from the hot-melt head, it will cause the hot-melt surface to be drawn, deformed, and burnt badly, and the hot-melt wrapping force is very small, which cannot meet the power battery pack manifold and plastic fixing used in vibration conditions. The problem of structural strength requirements
