  EVT introduces EyeVision 3D PinInspector

4. June 2018 – With the PinInspector, EVT's creative department has optimized a method for inspecting connectors and inspecting pins. The PinInspector contains as a finished system:

  • specially adapted EyeVision 3D image processing software with a prefabricated inspection program
  • Laser triangulation sensor EyeScan AT 3D
  • compact industrial PC
  • linear axis (optional)

Connectors have for some industries a meaning that we sometimes can not even grasp. The development of a connector should take into account several different requirements in terms of design and manufacturing process.

When transferring high energy such as batteries and generators or motors, it should therefore be borne in mind that sometimes it also involves the transmission of data and signals. Take, for example, a train signal. What happens if it fails and two trains collide?

Some faulty connectors, deep in electronics in cars, in trains, in airfields, could have catastrophic consequences.

1. Measure the true position

On the one hand, the software performs a measurement of the so-called wobble circle. These are gauges for measuring connector tolerances and pin staggering.

And one more thing is the measurement of the embedment depth of the pens. Thanks to the 3D inspection, it is possible to measure the height of the pen tip. In addition, the pin tips are measured not only in the x and y direction, but also in the z direction.

2. Pin Height

Further, the system may contain errors such as if the pins are straight or bent, if the pins are too deep in the housing or the pins protrude too far out of the housing.

The PinInspector is also precise. The laser triangulation sensor provides 2048 points per profile in a time of 25,000 profiles per second. "Laser triangulation" means that a camera follows a laser line that is projected onto the scan object and the line profile and height information is calculated from this captured image. When driving over the scan object under the camera, several profiles are generated, from which a 3D image is created.
