MVC Industry Overview

Over the past two years, MVC has increased its presence in the medical industry through many high-end custom vision solutions. Our solutions include: glass slide inspection, bottle fill height measurement, mechanical heart valve inspection, dry powder inhaler device inspection, staple suture inspection. Additionally, we have provided formal IQ, OQ, and PQ documentation.

Glass Slide Inspection

On-line machine vision system that provides product inspection for printed microscope slides. The inspection system measures the size and squareness of the slide, measures the chamfers in the corners of the slide, inspects the quality and placement of the print on the slide, inspects the quality of fiducial marks, and identifies glass defects such as chips, scallops, scratches, or embedded glass.

System & Vision Requirements

  • Perform geometric and surface inspection of glass slides 8 microns/pixel resolution. Images are 40 Megabytes in size.
  • System performs critical measurements to ensure slide quality including precisely locating and inspecting key features on the slides that will be later used by automated laboratory testing equipment
  • Slides are in process and are inspected at the rate of 1 per second. Turnkey system handles slides from infeed through inspection and slide disposition to outfeed stage. Integrated directly into existing fabrication line.
  • Unique MVC designed pick and place rejection mechanism allows rejects to be sorted by defect type
  • System provides SPC information on slide quality measures.
  • Custom Calibration and Gage R+R tools provided.
  • As built documentation, drawings.
  • Complete IQ/OQ/PQ qualification and validation.
