Core Components of the Automatic Assembly Machine

A complete motor assembly system consists of several intelligent modules.

Each module can be customized according to motor specifications and customer production requirements.

Working Principle

The automatic motor assembly machine follows a standardized assembly sequence.

Step 1: Component Feeding

Rotors, stators, bearings, shafts, end covers, and screws are automatically fed into designated positions.

Sensors verify component presence before assembly begins.

Step 2: Product Identification

Barcode or QR code scanners identify the product model.

The machine automatically loads the corresponding assembly parameters.

Step 3: Precision Pressing

The servo press machine performs critical operations such as:

• Bearing insertion
• Shaft pressing
• Rotor assembly
• End cover installation

The system monitors pressing force in real time.

Any abnormal force values trigger alarms immediately.

Step 4: Screw Fastening

Automatic screwdrivers complete fastening operations.

The torque monitoring system continuously verifies:

• Torque value
• Tightening angle
• Screw presence

Defective products are automatically rejected.

Step 5: Process Monitoring

Every assembly step is recorded.

Data includes:

• Cycle time
• Torque values
• Pressure curves
• Operator information
• Product serial numbers

This ensures complete traceability.

Step 6: Finished Product Unloading

Qualified products are automatically transferred to the next process.

Optional module transfer systems can be integrated for fully automated logistics.

Optional Configurations

JOIN offers flexible customization according to customer production requirements.
