17.1 OVERVIEW
264 TECHNICAL REFERENCE MANUAL Vol 1 E By DEK 04/2019
The camera assembly traverses horizontally in the X and Y axis to position the camera to carry out
the following functions:
●
Board Stop
●
Fiducial Capture - for stencil to board alignment
●
Site Capture - pre and post printing for 2Di inspection
●
Moving the Underscreen Cleaner
Positioning of the camera assembly is carried out by the X and Y drive mechanisms.
The camera contains an optical unit for image focusing and a lighting unit for board and stencil illu-
mination during fiducial and 2D camera capture operations.
The camera carriage also contains the following:
●
Camera Board Stop
●
Board at Stop sensor
●
Board Stop Extended Sensor
The camera board stop is a pneumatically driven unit which is lowered to stop the board in position
ready for clamping and vision alignment to take place.
The board at stop diffuse background suppressed opto detects the board when it reaches the
board stop. This starts a timer which when elapsed stops the belts and clamps the board.
The board stop extended sensor is fitted to ensure that the board stop is raised before any camera
carriage movement is demanded.
The camera positions are referenced from the home position. Each camera axis only homes during
initialisation, which can be from power-up or exiting diagnostics.
The camera system also provides the drive mechanism for the under screen cleaner.
The camera used by the camera system is the Hawkeye 750.
