Automatic Inductor Coil Winding and Soldering Machine

Overview of the 20-Spindle Winding Machine Line

The 20-spindle automatic winding line is a next-generation solution engineered for ultra-high output and reliability.
It integrates every essential stage of inductor or transformer production — including auto bobbin feeding, loading, copper wire winding, taping (optional), flux dipping, solder dipping, and unloading — into one seamless automation flow.

Each spindle is individually controlled for synchronized operation, ensuring all 20 coils are wound simultaneously with consistent precision.

This machine is ideal for manufacturers handling large volumes of SMPS transformers, ferrite inductors, EE/EFD/PQ cores, and similar products where efficiency and repeatability are key to business success.

Key Highlights

• 20 Spindle Simultaneous Winding — High-speed multi-spindle system for mass coil production.

• Automatic Bobbin Feeding & Loading — Vibrator bowl with auto orientation, no manual handling required.

• Auto Unloading to Soldering Station — Robotic transfer for clean and efficient operation.

• Auto Flux & Solder Dip — Uniform solder quality across all coil terminals.

• Optional Taping Unit — Add taping process post-winding for insulation if required.

• Integrated Control System — PLC + HMI-based interface for easy parameter setup and monitoring.

• High Accuracy & Repeatability — Ensures identical output across all spindles.

• Compact, Modular Design — Occupies minimal floor space for factory efficiency.

Machine Structure & Design

The 20-Spindle Automatic Winding Line is built with robust mechanical construction, ensuring durability and stability during long production cycles. The base frame is made from high-quality steel for vibration-free operation. Each spindle assembly uses servo motors for independent control of winding speed and pitch.

Key components include:

• Vibrator bowl feeder for automatic bobbin feeding
• Pick & place robotic loader
• Main 20-spindle winding machine
• Auto unloading system
• Dual soldering station (flux + solder)
• Optional taping and testing units

The layout can be customized based on client requirements, ensuring seamless integration into existing factory lines.

Machine Working Process

Step 1: Automatic Bobbin Feeding
The process starts with an automatic vibrator bowl feeder that continuously supplies bobbins to the system. Each bobbin is aligned and oriented correctly before entering the loading section.

Step 2: Auto Bobbin Loading
Using pneumatic or robotic pick-and-place mechanisms, each bobbin is loaded into the winding fixture precisely. The machine ensures exact positioning to maintain accuracy during high-speed winding.

Step 3: High-Speed 20-Spindle Winding
All 20 spindles operate simultaneously, winding copper wire according to the programmed number of turns and pattern.
Each spindle is servo-controlled, allowing independent speed adjustment, pitch control, and tension monitoring.

Step 4: Optional Auto Taping
If the product requires insulation taping after winding, the optional auto taping module can be added. This ensures each coil is wrapped with consistent tape tension and overlap.

Step 5: Auto Unload & Transfer
After winding, the machine automatically unloads finished coils from the spindle fixture and transfers them to the next stage (soldering station).

Step 6: Auto Flux Dip & Auto Solder Dip
The coils pass through an automated dual-dipping system — first in flux, then in molten solder.
This ensures clean, durable, and reliable solder joints with precise dipping depth and timing control.

Step 7: Optional Core Assembly & Testing
Post-soldering, additional automation modules can perform ferrite core insertion, taping, and electrical testing (LCR measurement). These add-ons transform the machine into a complete inductor production line.

Step 8: Final Unloading
The finished coils are automatically placed in collection trays, ready for packing or further assembly.
