Solenoid Valve Coil Winding Automation with NACHI MZ07L

Industry > ElectronicsApplication > Loading·UnloadingSector > Manufacturing

This industrial robot solution utilizes the NACHI MZ07L to automate the coil winding process for solenoid valves. By using a single robot to manage two winding machines simultaneously, the system minimizes idle time and maximizes production throughput through continuous operation.

Components

Robot	Robot: NACHI MZ07L Type: 6-axis articulated industrial robot (Long-arm model) Payload: 7kg Reach: 912mm Weight: 38kg Repeatability: ±0.03mm Protection Rating: IP67 (Dust-tight and water-resistant)

Workflow

STEP 1.	Picking: The robot picks up the raw coil frame (bobbin).
STEP 2.	Loading: The frame is inserted into one of the two active coil winding machines.
STEP 3.	Retrieval: Once the winding is complete, the robot picks up the finished coil.
STEP 4.	Outfeed: The finished product is discharged onto the outfeed conveyor.

Key Features

Productivity Boost & Space Maximization

Continuous Operation: Achieves a significant increase in productivity by performing seamless, idle-free tasks 24/7.
Dual Machine Tending: Utilizes a compact robot with an extended reach to simultaneously manage two winding machines positioned on either side.
Compact Footprint: Despite its wide working radius, the robot’s small base allows for installation in tight manufacturing cells where space is a premium.

Implementation Results

ROI Period	20 months
Key Metrics	Consistent productivity growth through automated continuous manufacturing.
Client Feedback	We initially thought our limited floor space would make robot automation impossible. However, by implementing the MZ07L—which is compact yet offers a wide working radius—we were able to install and operate the system highly effectively.
