HOLS Automatic Assembly & Test Line for Automotive Electronic Water Pumps

Electronic water pump acts as a core precision component for new‑energy vehicle thermal management systems, imposing stringent requirements on assembly accuracy and sealing performance. HOLS delivers a fully automatic turn‑key assembly‑test production line for automotive electronic water pumps, built upon circulating pallet conveying architecture. The line integrates precision pressing, quantitative dispensing, inline inspection and comprehensive performance testing, supporting mixed‑model simultaneous production for multiple pump variants.

Core Production Processes

Covering full‑range manufacturing workflows for power core assembly, sealed housing assembly, electronic control component integration and finished‑product validation, the complete line eliminates demands for additional segmented auxiliary equipment.

• Servo pressing for impeller, PCB, bearing and sealing ring

• Automatic stator tightening

• Dispensing & oil injection for thermal grease and activator

• Component loading & positioning

• Axial‑gap inspection

• Laser cleaning

• Quantitative thermal‑grease dispensing

• Cover plate spin‑riveting

• Machine vision inspection

• Air‑tightness testing for hydraulic and electrical assemblies

• EOL end‑of‑line comprehensive test: function validation and PCB flashing

• Height measurement, final cleaning and laser marking

Core Advantages

Industry‑Leading Cycle Time ≤ 10 s per unit

Optimized process sequences and material‑handling logic realize a remarkable cycle time ≤10 seconds per pump. The high‑throughput architecture maximizes production capacity and empowers customers for large‑scale mass manufacturing of new‑energy thermal‑management components.

High‑Flexibility Mixed‑Model Production

Balanced production rhythm supports mixed‑line manufacturing of multi‑specification electronic water pumps. Fast model changeover adapts to mixed‑batch, multi‑variant production requirements for automotive Tier‑1 manufacturers.

Multi‑Layer Error‑Proofing for Reliable Quality

Multi‑modal validation combining machine vision and sensor monitoring runs through the whole workflow. Intelligent error‑proof functions mitigate assembly defects, guaranteeing high precision and consistent batch quality for automotive‑grade water‑pump products.

Modular Station Layout for Easy Upgrade

Modular station‑based mechanical layout delivers stable, low‑noise operation. The architecture simplifies future new‑product introduction, line retrofitting and capacity expansion as customer product portfolios evolve.
