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.

1.4 Interface With Extenal Devices

(1) ① is the 14-Pin READY OUT (IN) connector for use when the machine is

configured with other equipment in an on-line environment.

The pin layout (assignment) of the connector for a Ready OUT (IN) signal differs

as shown in Tables 1.4.1 and 1.4.2 depending on the board transfer direction

(from left to right, and from right to left, respectively).

(2) ② is a DSub 25-Pin connector for the printer (conforming to the Centronics

Interface standards).

See Table 1.4.3 for the pin assignment of this printer connector.

③ is an Ethernet connector (8-pin modular type connector).

See Table 1.4.6 for the pin assignment of this Ethernet connector.

④ is a connector for interface with a matrix tray changer (50-pin).

⑤ is a power connector for a matrix tray changer (7-pin).
