In the context of industrial automation aimed at the market of assembly machinery, Sirius Electric, has studied and built a new pneumatic actuator for spin welders.
With this technology, most thermoplastic materials having a round shape can be welded.
In the spin welding technology, the heat needed to melt the parts is produced by a circular movement combined with thrust pressure. A part to weld is held in the fixturing, while the other part is put in motion by the rotary spindle. The assembly process is easy and based on easily understood, well-known principles of physics. This actuator, very contained in size, is suitable for welding small size pieces, where the use of conventional systems is inconvenient because of size and elevated costs.
The brushless motor that drives the rotary spindle is highly efficient. The new electronic drive devices on these motors, combined with our welding cycle control microprocessor, are perfectly
integrated, further reducing the space needed for the wiring system.
