Mark Camera

Objective:

Given a CP-7-series machine,

technical documentation and

required tools, remove, replace and

calibrate the mark camera to FUJI

specifications.

7.1 The Mark Camera

This CCD camera is mounted on the machine for reading fiducial and block skip

marks. The machine processes fiducial marks in order to find the actual position

of the board inside the machine and so place parts accurately. Block skip marks

are processed in order to ascertain whether a particular block(s) are to be skipped

or not (refer to the figure below).

Typical problems arising from an incorrectly calibrated position include mark read

errors, and uniformly skewed parts.

Recalibration of the fiducial camera is needed to correct the above mentioned

problems. Some examples of possible reasons for calibration are:

- Poorly focused camera

- After replacing camera

- After any damage to the camera resulting in camera skew

Required Tools: 1 Set of Allen Wrenches

Required Jig: Pin holder jig

Fiducial jig plate
