Chapter 7 Camera Adjustment
Parts Cameras
Two 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 data to ensure that the part’s
dimensions are within specified tolerances.
Problems that arise from an incorrectly adjusted camera include displaced parts, high error rates, and
skewed parts. Some other examples of possible reasons for re-calibration are:
Lens replacement
Camera replacement

7.1 Parts Camera removal
1. With the machine power OFF, remove the video cables from the cameras.
2. Remove the cameras from the machine.
3. Remove the four mounting bolts from the right hand side of the bracket and carefully remove the
cameras. (The four bolts within the rectangle in figure 2). When replacing the camera, the torque
value for tightening these bolts is 0.98N.m. (10Kgf/cm)

5. When installing the lens unit, apply a small amount of Loctite 425 to the threads and use a 3.92Nm
(“C-Type)” torque wrench to secure the lens unit.

7.3 Camera Set-up Procedure
Firmware version V1.18 features a new brightness adjustment function. Use of this function requires a
change in the camera adjustment procedure in order to perform resolution measurements at the
appropriate brightness. Refer to the following diagram for the correct order of adjustment.
