Introduction

This production line is used for the automated assembly of the CTC energy storage integrated frame PACK components. The AGV flexible logistics system facilitates the automatic assembly process of the M23 energy storage, significantly improving production efficiency and stability. The main equipment includes lower box online, cleaning and pasting TC composite pieces and insulation strips, PACK lower box robot automatic gluing, module inversion into the box, installation of CMC with foam silicone pad, module pole addressing, manual assembly of CCS accessories, module Busbar welding, post-weld inspection and polishing, manual installation of plastic support buffer pad and low-voltage wiring harness with module TC tape pasting, installation of high-voltage connection and high-voltage protection cover, installation of mica plate for balance valve and explosion-proof valve, installation of high-voltage box protection cover, installation of upper and lower cover sealing strip and buffer pad, PACK box water-cooled plate airtightness testing, EOL testing, charging and discharging testing, heating and static station, weighing, and offline equipment.

Highlights

  • The production line features a flexible design, allowing for the change of different blueprints with just one click.
  • The assembly process for the core station battery module involves the flipping clamp automatically grabbing and flipping the glued PACK lower box to complete the action. The Beam modular car is then automatically transported to the module into the box station through the AGV flexible system, integrating heavy-duty flipping lifting technology to invert the module into the lower box, further enhancing the efficiency and stability of the assembly process.
  • The core workstation for PACK module pole addressing and module Busbar welding is integrated with AGV flexible transportation docking, enabling fully automated detection of the relative position and height between module Beam battery cells. This data is fed back to the welding station, where flexible measurement, monitoring, and compensation are carried out through a robot vision system and welding mirror system. This ensures the accurate welding of the PACK battery cell group and completion of the product welding tasks. The AGV system and robot flexible welding system further enhance the stability of the assembly process.
  • For the first time, the validation PACK heating static test was adopted. The CTC frame was pushed into the positioning mechanism through the frame car to complete the positioning of the frame body, which was then monitored by servo and force displacement sensors. The heating mechanism’s lifting and lowering used pneumatic linkage components, allowing for rapid heating of the CTC PACK component. The heating temperature, curve, time, and other parameter data are uploaded and monitored via the MES server, with the data displayed on the HMI for easy reading and viewing by personnel. This setup allows for quick and real-time monitoring of heating data, thereby improving product manufacturing efficiency and stability.
