Fully Automatic Relay Coil Production Line

Fully Automatic Relay Coil Production Line

Machine  introduction

Dominate the Market with Ultra-High Efficiency

Designed for the mass production of Automotive, Power, and Communication Electronics Relays, the SIPU Fully Automatic Relay Coil Production Line is the ultimate solution for factories aiming to cut labor costs and maximize output.

Equipped with a 32-spindle winding station operating at 20,000 RPM, this line delivers an impressive 4,000 pieces per hour. It integrates bobbin loading, pin insertion, winding, soldering, and testing into one seamless automated process—turning raw materials into finished coils with zero manual intervention.

Process

From Bobbin to Finished Coil: A One-Stop Journey

This turnkey line connects multiple stations to ensure consistent quality:

1. Auto Loading: Bobbins are fed automatically via a Vibration Bowl Feeder.

2. Pin Insertion: High-precision insertion of terminal pins into the bobbin.

3. High-Speed Winding: 32 spindles working simultaneously for maximum throughput.

4. Precision Soldering: Automatic flux application followed by dip soldering for reliable conductivity.

5. Smart Testing: Resistance testing (Ohm check) to automatically reject NG parts.

6. Unloading: Finished coils are conveyed to the packing area.

Key Features & Benefits 

Massive Output (32-Spindle System):
Unlike standard 12 or 16-spindlemachines, our unique 32-spindle design doubles your production capacity, reaching up to 4,000 pcs/h. Omatchne machine does the work of two.

1. High-Speed Precision (20,000 RPM):

Equipped with high-speed bearings and S2M timing belts, the winding axis operates smoothly at 20,000 RPM with low noise, ensuring tight and neat coil layering.

2. Labor-Free Operation:
The fully automated process means one operator can manage the entire line, significantly cutting down your labor expenses.

3. Zero-Defect Quality Control:
Integrated Resistance Testing Station checks every single coil. Defective products (open/short circuits) are automatically screened out, ensuring 100% yield for your shipment.

4. Easy CNC Programming:
The intuitive Touch Screen Interface (HMI) allows operators to easily set winding speed, turns, and direction. No complex coding skills required.

 Application

Perfect for manufacturing various relay coils:

• Automotive Relays (EVs, traditional cars)

• Power Relays (Industrial control)

• Communication Relays (5G, Telecom)

• General Purpose Relays (Home appliances)

FAQ

Q1: What is the maintenance interval for the spindle belt?

A: The machine uses high-durability S2M timing belts. Under normal operation, they require minimal maintenance. Replacement is simple and can be done by your operator using standard tools in just a few minutes.

Q2: How does the soldering station ensure quality?

A: We use a two-step process: first, an automatic flux applicator ensures the wire is ready for bonding; second, the precise dip-soldering bath ensures a solid electrical connection without overheating the bobbin.

Q3: Can this machine handle different bobbin sizes?

A: Yes. The machine features a modular fixture design. By changing the customized fixtures (jigs) and adjusting the program, you can switch between different relay coil models.
