With the PinInspector the EVT Creative Department has optimized a method for the inspection of connectors respectively the inspection of pins. The PinInspector contains as a ready-to-use system:

• specially adapted EyeVision 3D machine vision software with a ready-made inspection-program-kit
• lasertriangulation sensor EyeScan AT 3D
• compact industrial PC
• linear axis (optionally)

Connectors have meanings for some industries that we sometimes cannot even grasp. During the development of a connector for several different demands concerning design and production process should be taken care of.

Therefore during transmission of high energy such as batteries and generators or engines it should be taken into account that sometimes it also concernes the transmission of data and signals. Take a train signal for example. What happens if it fails and two trains collide?

Some faulty connector, deep down in the electronic system in cars, in trains, in airplains could cause catastrophic outcomes.

1. Measure true position

For one thing the software is carrying out a measurement of the so called wobble-circle. These are gauges to measure connector tolerances and staggering of the pins.

And another thing is the measurement of the embedment depth of the pins. Thanks to the 3D-inspection it is possible to measure the height of the pin tip. And additionally the pin tips are not only measured in there x- and y-direction but also in z-direction.

2. Pin-height

Furthermore, the system can detect flaws such as e.g. if the connector pins are straight or bent, if the pins are stuck too deeply into the housing or if the pins stick out too far out of the housing.

The PinInspector is also precise. The laser triangulation sensor delivers 2048 points per profile in a time of 25.000 profiles per second. “Laser triangulation“ means that, a camera is following a laser line which is projected onto the scan object and from that captured image the line profile and height information are calculated. During the passing by of the scan object under the camera, several profiles are created, which are used to make 3D image.
