MINIC II
Compacting Station (Ultrasonic Welding) The Schunk MINIC II ultrasonic welding station can be used on the CrimpCenter series of fully automatic crimping machines for compacting (e.g. tip welding) of stripped wire ends from 0.22 – 6 mm2. The system includes the MINIC II station with swinging system (sonotrode) and a separate control unit with high frequency generator. The system also includes a PC,monitor, keyboard and mouse.
The CrimpCenter swivel arm positions the stripped wire end into the ultrasonic welding tool of the MINIC II station. Continuously adjustable servo drives close the tool according to programmed welding parameters. The sonotrode applies the mechanical vibration to the parts to be welded. The entire welding process is monitored and analyzed in realtime. User-friendly, multi-lingual menu structures, supported by graphical displays, provide for easy programming directly at the control unit.
Special Features
- Reliable compacting (tip welding) of stripped wire ends (e.g. CU or Al) with proven Schunk ultrasonic welding technology
- Possible to weld connections of copper and aluminium
- Integrated good / bad sorting
- Short cycle times, low heat exposure of wire strands during compacting
- Programmable for different wire cross sections with processing parameters for each wire stored in PC for easy recall
- Low-wear Sonotrode with 2 changeable connecting plates (reworkable)
- Quality assurance with automatic recording of key quality measurements (e.g. precompacting / compacting specifications, welding time and welding energy)
Machine Configurations
Possible machine configurations and combination with crimping, sealing or other processes depend on the number of available stations of the CrimpCenter model.
