Tailored automation

The sysmelec® high precision automated machines are realized according to the customer specifications. Based on proven automation principles, the design of the machines ensures robustness and reliability. Their main characteristics are as follows:

  • Integration of demanding attachment processes, especially appropriate for the assembly of microtechnical products; these processes include: laser welding, gluing, driving into position with force control, micro-screwing and many others
  • Handling of miniaturized, delicate and/or flexible products
  • Handling and shaping of wires with very small diameters or wires that are very sensitive to mechanical stresses, especially tensile strength
  • Integration of real-time measurements in order to control one or more robots in a cell
  • Integration of intelligent tooling which, combined with one or more robots per machine, makes the machine either more flexible (in the case of several variants) or more robust
  • Design guided by customer performance specifications – sysmelec® assembly machines provide typical cycle times ranging from 2 to 30 seconds, depending on the applications
  • Integration in the customer’s IT environment
  • Clean room and/or medical-compatible execution, if specified

Application examples

Thanks to its sysmelec® trademark, Unitechnologies has deep roots in the watchmaking industry, which allowed to build up a wide experience and a unique know-how in the automation of watchmaking processes as well as in the precision assembly, the handling and the measure of delicate watch components. A few selected examples of watchmaking processes:

  • High precision jewelling and mounting
  • Assembly of T1 and T2 watches
  • Assembly using micro-screwing
  • Fully automated hand-fitting (needle)
  • Assembly of sub-assemblies for external parts of watches, cases, wristlets, etc.
  • Welding and laser marking of internal and external watch parts
  • Volumetric dispensing of points and beads with glue and grease
  • Loading/unloading of watchmaking components onto machine tools
  • Engraving of parts
