Parts Cameras

Objective:

Given a CP-7-series machine,

technical documentation and

required tools, remove, replace and

calibrate the Wide and Narrow

cameras to FUJI specifications.

8.1 Parts Cameras

These CCD cameras are mounted on the machine for inspection of the parts picked

at the first station. The raw image is captured by the cameras and compared with

part related data in part data to ensure that the part’s dimensions (within specified

tolerances) are correct (refer to the figure below).

Problems arising from an incorrectly positioned/calibrated camera include

uniformly displaced parts, high error rate due to problems occurring during image

acquisition, and uniformly skewed parts.

Recalibration of the parts cameras is needed to correct the above mentioned

problems. Some examples of possible reasons for calibration are:

- lens replacement

- camera replacement

Required Tools: 1 Set of Allen Wrenches

1 dial gauge

Required Jig: Calibration jig

10st cam lever spring stopper jig
