An Orthopedic medical device manufacturer required a method to automate the inspection process of laser marked medical devices. Without the right integration techniques, automating tolerances of five to ten thousandths of an inch can be difficult for even with the most advanced systems. Prior to installation, our client used a tedious process involving a table top smart scope, calipers and precision height measurement tools as well as a visual check for defects.
Why Choose Canyon Run Engineering?
Canyon Run Engineering was chosen due to the combination of precision automation equipment experience and medical device design skills. Canyon Run has experience in high accuracy inspection equipment and the need for verification and validation during processing. Our experience in automation controls along with data collection was key to the success of this automated unit as part tracking is paramount.
The new system used a tele-centric lens that prevented parallax distortion and allowed for precision measurement in a 3D space. Canyon Run Engineering designed a custom machine as part of the complete vision calibration system. A fixed camera took two pictures, 180 degrees a part, as a rotary axis turned the part for a complete and quick inspection. Maintaining high accuracy and repeatability were the main accomplishments of the new vision system. Target time for the inspection process improved from several minutes per inspection to one minute.
Key Features: Locating critical features and measuring dimensions, Tele-centric Lens – eliminates perspective distortion for accurate measurements, five to ten thousandths tolerance, rotary access allows system to check both sides of the part, reduced inspection time, fixed camera with rotating parts.
