Desoutter has now developed a so-called "virtual cable" with which the action radii of the tools or employees can be individually defined. This radio-based function means that the connected screwdrivers can only be operated within specific, narrowly defined coordinates. The new solution is based on Desoutter's Connect control system, which monitors the tool position in the room and thus ensures component-related traceability. Assembly errors and quality problems can be minimized in this way, and the flexibility of the cordless screwdriver is maintained.

Installation: Tracking base and tracker

Only two things are required for the setup: a so-called tracking base, which is connected directly to the control unit, and a tracker attached to the tool. The tracking base and tracker communicate wirelessly via ultra-wideband technology (UWB), which uses the frequency range from 3.5 to 6.5 GHz and does not interfere with other wireless networks. The desired working range is very easy to define and teach-in; in principle, all you have to do is press the start button on the tool. Alternatively, the desired minimum and maximum radii for freedom of movement can be stored in the Connect control unit or programmed using the CVI Config software from Desoutter. The resolution of the system is around 30 cm.

A tracking base can be used to link and monitor up to eight tools within a work area or up to eight work areas with one tool each. In turn, up to eight tracking bases can be controlled via each Connect. One acts as the primary base; the other seven can be installed within a maximum radius of 20 m and managed in slave mode. They also synchronize with the primary base via radio, so no additional cables are required.

The virtual cable can be extended to any number of tools from Desoutter's current product portfolio and retrofitted at any time. The compact tracker is simply attached to the top of the Desoutter cordless tool so that it does not interfere with handling. No additional battery is required to operate it, as it is powered by the tool. And an interesting side effect for some users: it reduces the risk of battery-powered tools getting lost on larger assembly lines in the factory.

In the meantime, the virtual cable has already proven itself in practice during various field tests at a number of car manufacturers and suppliers. Meanwhile, Desoutter is already planning the next step: in future, the virtual cable will also be available for "angular spaces" and moving objects where the permitted space follows the speed of the production line. These features can then also be easily retrofitted.
