Customer case: Chongqing Zhixin Guiyang Base × Hongguang Group intelligent gluing system

Five-axis linkage visual dispensing technology solves the packaging problem of electronic control modules for new energy vehicles

Customer pain points

As a core supplier of BYD, Geely and other car companies, Zhixin Guiyang Base will undertake the production of electronic control modules for an 800V high-voltage platform in 2025:

  • Conventional dispenser pairs Special-shaped cavity (R angle ≤0.5mm)The coverage rate of rubber circuits is less than 82%
  • The fluctuation of the curing time of the conformal adhesive is caused The production capacity per hour is stuck at 120 pieces
  • The dispensing thickness tolerance ± 0.15mm exceeds the requirement of 0.05mm ± automotive grade

Technical solution highlights

Patent No.: ZL2025 3 0254687.2

  • 5-axis linkage compensation system:XYZ linear axis + UV rotary axis synchronous compensation, adapting to 15 kinds of special-shaped cavities
  • AI vision closed-loop control:The 20 million pixel high-speed camera detects the glue width in real time, with an accuracy of ±0.02mm
  • Two-component dynamic compound:The screw metering system with PID temperature control has a mixing ratio error of <0.3%

“In response to the miniaturization challenge of new energy electronic control modules, [your company] equipmentSub-micron vibration suppression algorithmandGlue volume prediction model, allowing us to complete the process verification that would have taken 2 months in 15 days. “

—— Chen Lifeng, Manager of the Process Engineering Department of Zhixin Guiyang Base

Technology extends value

  • The equipment data is connected to the factory MES system to realize real-time prediction of glue consumption and feeding
  • The accumulated 15 special-shaped dispensing process parameter packages are reused for the other 3 production lines
  • The energy consumption of the equipment is reduced to 2.8kW·h/hour, which is 41% more energy-saving than the imported model
