Gear Backlash Adjustment
(1) Set the cam angle to 0°.
(2) Place the dial gauge on the gear teeth as shown below.
(3) Loosen the housing bolt on the machine main body.
(4) Turn the gear shown below by hand. Tap the housing with a rubber
hammer until the amount of gear backlash is 0.1 mm.

5.4 Station 4
At station 4, the part is vision processed. Station 4 is made up of a CCD
camera, a UV lamp, and a prism box. Also, a front light may be installed
(optional).
Standard Specifications (Backlighting)
(1) Light from the UV lamp reflects off the fluorescent disk.
(2) The reflected light hits the part and reflects the image of the part onto
the prism.
(3) The part image reflected off the prism is reflected at and permeated
through another prism.
(4) The reflected image goes to the wide view CCD camera, and the
permeated, to the narrow view CCD camera. The CCD camera which
is used is specified in the MCS/2 Part data.
(5) Either the wide or narrow view camera sends information and
compares it with what is in Part data, and the machine decides
whether or not to place the part. If the part is to be placed,
information on X, Y and theta coordinates is sent out to correct errors
produced by sliding. The XY table adjusts itself and fine theta is
carried out at station 6.

Front Lighting Specifications
To use the front light, Part data item 13.Lighting must be set to
Front_ligt. Proper data item 126. Frontlight must also be set to Use.
1. The halogen light shines from the front light onto the prism.
2. The halogen light passes through the prism then simultaneously
reflects onto the part leads and returns to the prism.
3. The part image reflected off the prism is reflected at and permeated
through another prism.
4. The reflected image goes to the wide view CCD camera, and the
permeated, to the narrow view CCD camera. The CCD camera which
is used is specified in the MCS/2 Part data file.
5. Either the wide or narrow view camera sends information and
compares it with what is in Part data, and the machine decides
whether or not to place the part. If the part is to be placed,
information on X, Y and theta coordinates is sent out to correct pickup
deviation. The XY table adjusts itself and fine-theta is carried out at
station 6.
