OptiCheck-Software for board processing inspection.
OptiCheck-Software follows the principles of image comparison based on most recent methods of colour image processing and recognition.
It works using these steps:
- the scanner unit, the Scan-box of the TT-System for off-line operation, or the Conveyor-Box of the in-line system scans the board to be checked and offers a two dimensional colour image to the computer for further validation.
- following a predefined checkplan the system validates the part positions (check areas)using the dimensions and algorithms defined in the library. Like a placement plan of a pick-and-place OptiCheck „knows“, at which position a certain part can be expected.
- Existence or absence?
- Correct colour according to a reference image and tolerance pattern?
- Exact positioning inside of the tolerance frame?
- ... inside the accepted rotation tolerance?
- Existence and position of the polarity marker?
- Label and markers or parts?
- Appropriately defined contact spaces are checked additionally for bridges.
OptiCheck-Software is able to recognize:
