The Vision Unit Illuminated (VUI) is a compact unit comprising a camera, illumination, and focusable optics complete with liquid lens technology. It significantly reduces installation and commissioning labor and, thanks to focus adjustment during runtime, it is particularly well-suited for work with changing component heights, as is common in logistics applications. What’s more, all functional components are encased in elegant IP65/67 anodized aluminum housing.

An all-in-one solution comprising a camera, illumination, and focusable optics

When it comes to image acquisition, the PLC controls all settings for the individual functional components (camera, illumination, lens) during runtime via EtherCAT with high precision and is perfectly synchronized with all processes in the application. In this way, direct adjustments to different working distances, for example, can be made by electronically adjusting the focus position.Along with the intensity and length of the light pulse, the light color and other parameters of the image acquisition camera can also be controlled via EtherCAT. Focusing during runtime is facilitated by a robust liquid lens that can be used in any position. It also offers exceptional shock and vibration resistance in addition to an extremely long service life on account of the high number of cycles.

EtherCAT supports highly accurate time synchronization of all devices network-wide

Due to the synchronization capability of the EtherCAT devices via distributed clocks, pulse operation is easy to implement, since no external trigger loop is necessary for the camera or illumination. The integration of EtherCAT into TwinCAT means the pulse times of the illumination can be synchronized to all other EtherCAT devices in the network without additional hardware and software interfaces. The devices are equipped to support the high-precision time synchronization of all inputs and outputs, typically with time uncertainties of well below 1 μs. This applies both relatively – in relation to the devices in a network – and absolutely to a higher-level global reference time. Highly accurate time synchronization is fundamental for efficient flash operation and for sophisticated scenarios with multiple units, illumination sources, and cameras. It allows complete synchronization of the automation elements with the vision elements, which makes the system or machine extremely homogeneous and eliminates system boundaries.

Optimal image results through synchronization with distributed clocks

  • from the camera shutter
  • from the illumination shutter
  • from the pulse intensity
  • from the spectral adjustment of the light

Further advantages

Ability to adjust the image contrast during runtime for maximum flexibility

Multicolor LED illumination for each object can be individually adjusted as follows

  • three selectable channels (blue, green, orange) in the visible spectral range serve to optimize image contrast
  • a mixture of these three visible channels produces white light
  • IR850 offers an excellent light source to suppress visible features such as multiple print colors
