Manufacturing method of battery pack and manufacturing process monitoring system for the same

Abstract

The present invention discloses a method for manufacturing a batter pack from a plurality of battery cells via a continuous operation, the manufacturing method comprises: (a) putting the battery cellsin a bearing clamp, and mounting insulating covers onto the bottom end of each battery cells; (b) after positioning each of metal clads to one side of the top end of each one corresponding battery cells in the battery cells, combining the metal clads to top ends of each battery cells by welding; (c) mounting additive to bottom end of each insulating mounting components or top end of each batterycells, so as to combine the insulating mounting components to the top end of each battery cells; (d) after positioning each one of protective circuit modules to the top end of one corresponding insulating mounting module of the insulating mounting modules, electrically connecting the protective circuit module to each battery cells by using a preset welding equipment; (e) applying the adhesive to the outer surface of the top end of each protective circuit modules or the inner surface of each insulating top covers, and combining each insulating top covers to each protective circuit modules or each battery cells by this way, that is, the insulating top covers surround each protective circuit modules; (f) taking out the battery pack from the bearing clamp; (g) testing the performance of each battery pack by using a battery pack testing equipment, and transmitting the testing data (A) to a data server; (h) coating the outer surface of each battery packs in a protecting film, testing the barcodes attached to the outer surface of a protecting film, and transmitting the testing data (B) to the data server; and (i) testing the size of each battery cells by using a sensor, and transmittingthe testing data (C) to the data server.

Description

technical field [0001] The present invention relates to a battery pack manufacturing method and a manufacturing process monitoring system for a battery pack, and more particularly, to a method of manufacturing a battery pack from a plurality of battery cells through a continuous operation and A manufacturing process monitoring system therefor, the manufacturing method comprising the steps of: loading battery cells into a carrier jig while installing an insulating bottom cover to the bottom end of each battery cell; After each of the layers is positioned on one side of the top of a corresponding one of the battery cells, the metal cladding is bonded to the top of each battery cell by welding; an adhesive is applied to each insulating The bottom end of the mounting member or the top end of each battery cell to couple the insulating mounting member to the top of the respective battery cell; a corresponding insulating mount for positioning each of the protective circuit modules in...

AI Technical Summary

Problems solved by technology

[0009] However, a fundamental solution to the problem has yet to be proposed

This is because battery packs are mass-produced through precise assembly processes, so small errors are not easily confirmed in the production line, and because defects in battery packs or deterioration in battery pack quality are confirmed only after the battery pack is actually applied to the corresponding device
