X-Ray inspection is a technology based on the same principles as vision inspection. It uses X-rays as its source (instead of visible light) to inspect features which are typically hidden from view.
Images are created when X-Ray beams are projected through the object. As the X-Rays pass through the object, some radiation is absorbed, some is scattered and some is transmitted.
The radiation that is transmitted is measured and used to reconstruct a mathematical representation of the object.
Abstract applications for X-Ray machine vision are:
- Verify presence and connection of hidden components
- Find cracks, voids, or other flaws in assembled products
- Verify weld integrity
- Guide a robot for assembly
- Count the number of welds, teeth, slots, or other such features
- Perform a critical dimensional measurement
- Communicate with 3rd party equipment such as robots, PLCs, HMIs, and remote storage
- Take high-quality x-ray images in the field with portable detectors
We have experience with using X-Ray inspection for pharmaceutical needles inside their shield. Also we used this vision technology for inspecting Xenon lights bulbs for cars. Furthermore, X-Ray can be used for inspection of food products.
Specific precautions have to be taken into account to prevent exposure of operators to the X-Ray beam.
