  1. I'd like the ability to 'see' through 2mm mirror to inspect for a small rectangular piece of rubber behind the glass, do any xray cameras for machine vision exist for this application?
  2. I've inherited a mess of a project and am in need of assistance. I have an epson with an x-rite VC50 color sensor attached. The robot hits 4 points on the target (ABS plastic parts that come in shades of different colors) and determines if they're building with the correct parts based on control limits. The problem is, my target values are very similar and at times I get false passes. I honestly believe it's a limitation of the sensor. At this point I've 1. ensured the sensor is 1.5" away from the target and 2. ensured the sensor is at the recommended 30 degrees from the target - per the VC50 manual. I believe I'm in need of a color sensor with better resolution but I'm not sure where to look, any recommendations from you guys? Any way to get better readings with my current process (auxiliary light source maybe?) thanks!
  3. I have an assembly line that I run a variety of parts down. It's easy to mix the parts as there are a variety of small design differences between them - these "small" differences are critical to the customer and I have no good way to poka yoke a machine with sensors or a vision system due to the nature of the parts (difficult to fixture). One key difference is the weight. I envision a small scale on the side of the machine, operator places the part on the scale, analog value is sent to the PLC, if it falls within my control limits the part is released and the operator then assembles. Does a small scale exist for this application? parts are between .2 - 1.5 lbs, about 3" x 5".
  4. The problem: cracked or bent tabs upon installation of a Lexan 141 lens in to an ABS piece that causes rattles or vibrations for the customer. Need to be able to detect this condition and contain the part. Defect: Lens: ABS Piece: My first thought was mount a camera above the workstation and direct light in to the lens. Then use a camera to detect if the legs are bent. Below is an example. While the image is clear and the contrast is good, I doubt detection in this manner would last long due to part variance and slight changes in operator part placement. Anyone have another detection method I can try?
