HONG KONG Q.C. CENTER LTD.

Within the frame of quality assurance, the forged pieces of this client have to be checked in an inline inspection with respect to several parameters: Inner and outer diameters, as well as the absence of surface defects have to be verified. Video of inline forgings inspection for dimensional accuracy and surface defects with QuellTech LaserScaner. Particular Challenges Manual inspection carried out until now turned out to be not reliable enough, particularly after an increase in production. The final rejection rate has seriously affected the productivity of the entire manufacturing process. A solution for a contactless inline inspection was needed. The QuellTech Solution A testing station including an index table has been designed. This configuration acts as a support for two QuellTech Q4-60 laser scanners, used for inspection of the parameters mentioned above.

To meet the growing and increasingly complex demand for machine vision systems, CLA has developed the CLAsight® solution. It is a package consisting of hardware (frame, camera, optics, lighting and industrial computer) and a versatile vision software application for positioning, aesthetic or dimensional inspection, time measurement by direct reading of hands, dial and date, and optical character recognition (OCR). Adapted to your needs, it will be the eye of your robot or the controller of your parts. Application example : - OCR Vision system - Reading of the hands of a movement or a watch - Aesthetic inspection - Positioning of microtechnical parts
