Have a large model matrix? Machine Vision can be used to inspect many aspects of your products whether it’s a pallet full of parts traveling down a conveyor or a single part feeding down a track, Machine vision can be used to provide a 100% inspection of your products.
Cannot guarantee that your supplier is delivering parts within a specified tolerance? PMD has used Machine Vision to perform tolerance measurements on both incoming product as well as parts coming off an assembly process.
Code Verification (OCR, 2d grading, 1D)Generally sensors can be used to verify or test the proper assembly of client products. In some cases however, where it may be impractical to fit a sensor or when there are many model variations making many sensors impractical, machine vision can be used to test an assembly sequence.
PMD has implemented many tests that interrogate text or a code that has been printed either directly onto a product (DPM) or onto the products shipping container, label, packaging, etc… In some cases, OCR is required to verify that the proper text has been printed onto a package in other case a client is looking to verify that a barcode label has printed correctly.
Sometimes it is not practical to see a dispense media dispensed onto a product during the assembly process. In some of these cases a UV enhancer can be put into the dispensed media such that utilizing standard vision hardware in conjunction with a UV Lighting scheme the dispensed media can be seen with ease.
