A production line for positioning and stringing welding of accompanying batteries

Abstract

The invention relates to a traveling electric core positioning, series welding and assembling production line which comprises a fixing belt processing part, an electric core transportation part, a conductive belt processing part and an electric core combination part, wherein the electric core transportation part is fixed on a rack and used for transporting to-be-processed, being-processed and processed electric cores; the fixing belt processing part is positioned at the front end of the electric core transportation part; the electric core combination part is positioned at the rear end of the electric core transportation part; the electric core transportation part comprises an electric core conveyor belt; a plurality of electric core clamping jaws are arranged on the electric core conveyorbelt in a linear array; the fixing belt processing part comprises a fixing belt migration bracket; the fixing belt migration bracket comprises a puncturing roller; the conductive belt processing partis designed to be a structure capable of hot-pressing a conductive belt to the surface of a fixing belt; the electric core combination part comprises floating plates and supporting plates; the supporting plates are fixed onto the rack; the floating plates are connected onto the supporting plates through a plurality of groups of linear driving mechanisms; electric core press-mounting heads are connected onto the floating plates; and high-voltage electric discharge heads are mounted in the electric core press-mounting heads.

Description

technical field [0001] The invention relates to a production line for positioning and serial welding of accompanying electric cores, which belongs to the field of electric core manufacturing. Background technique [0002] With the development of new energy, there are more and more products such as electric vehicles; and its energy is mainly a battery pack composed of an array after series welding of lithium battery cells; lithium batteries are generally welded in series and fixed in battery packs It is transported through the relevant mechanical guide rails, and then the battery cells are fixed by the strength of the stringer strap itself; but because the stringer strap itself has poor metal fatigue resistance, for a battery pack with a larger capacity, the number of cells increases. , the stringing ribbon is easy to break or desolder due to excessive force during the process of loading the cells into the battery pack, which seriously affects the stability of the battery pac...
