Speaker Assembly Machine

What this machine is for

This machine assembles earphone speakers: the frame, pole pieces, magnet and voice coil are brought together, riveted, and the PCB is glued onto the assembled frame before the part drops into a tray. Coil position is the whole game on a speaker line, because a coil that sits off centre still plays, but it will not pass a distortion test.

Stations on the line

• Frame loading, with vibration plate
• Rivet loading, with vibration plate
• Pole pieces loading, with vibration plate
• Magnet loading, with vibration plate
• Automatic riveting, two units
• Glue dispensed onto the frame
• PCB unloading, one piece at a time, glued to the assembled frame
• Unload to tray

How the line is built

Each small part arrives on its own vibration plate, so orientation happens before the part reaches the fixture. The two riveting units work in sequence with the glue station, which is why the line can hold a steady rate without an operator handling the rivet.

Control is a Delta PLC with a Wenview touch screen, with a safety grating and guards on the moving parts.
