1.2.7 OCC parts identification

(1) Offset correction camera

The machine is equipped with a coaxial light and polarizing filter as the standard

devices. The camera detects a BOC mark and corrects the detected mark

automatically.

Adjusting the polarizing filter

1) Place a white ceramic board on the calibration block, then move the camera over

this board.

2) Loosen the screw to turn the filter holder to the right and left. When the screen

becomes brightest, fix the screw.

1.2.8 VCS parts identification

The VCS recognizes a component with the following devices: reflective/penetrative

lights, three-dimension movable light and coaxial light, then places on a board a

component such as a QFP, BGA, CSP and connector.

1.3 X, Y, and Z Axes Descriptions

The following four axes (X, Y, Z, and θ) are numerically controlled in this machine.

(1) X- and Y-axis

The X-axis represents the left and right directions of the machine, while the

Y-axis represents the front and rear directions: a position is given as X = 000.00

mm and Y = 000.00 mm in increments of 0.01 mm. Two coordinate systems are

available: one given by the production program and another given by teaching

operation. Both coordinate systems are automatically changed, so you do not

have to switch the coordinate system by yourself.

(2) Z-axis

The Z-axis represents the height, given as Z = ○○.○○ mm, in 0.01-mm

increments. The upward direction is positive (+), with the top side of a board

clamped (any jig is not used) being 0.

(3) θ-axis

The q-axis represents the rotation angle of the head, given as "A = ○○.○○" (in

0.05 increments.) The value is positive for counterclockwise rotation and

negative for clockwise rotation.
