Initial Situation:

Surface inspection of high security key

A security key producing client wants to be sure that keys satisfy several conditions. In this respect client wants each surface of the security key to be inspected including abutment area. Parameters, which client wants to measure are key bit width, profile (cut) shape (width and depth); position, shape and depth of dimples and grooves.

Particular Challenges:

Keys are made of a material having high reflectivity. Not only the material but holes and curved areas on key, in short detailed surface structure also make process even harder. Tactile inspection and quality verification is difficult on such tiny details because majority of the measurements are under the range of 1 mm. Additionally these are high security keys with more details requiring more sophisticated measurements.

QuellTech Solution:

A QuellTech Q4-20 Laser Line Scanner is well capable of measuring high security keys’ detailed surface structures with high precision. Depending on client’s quality requirements it is possible to determine fail or pass status of the keys.

Benefits for the Client:

QuellTech`s non-contact 2D Laser line scanner enables high process robustness, 100% inline inspection and less false errors. The system can yield 100% zero error rate, if some false positive errors are accepted. The QuellTech Scanner will improve quality and will reduce labor cost. Upon request of client, the QuellTech inspection system is capable of inspecting a security key in between 0,05 … 0,5 seconds. This means the scanners can be used to test 100% of all parts in an inline configuration.
