4.1.8 Transport Conveyors Module

The transport conveyor is a programmable width system, designed to transport the board through

the machine (using belts) and to secure the board during the print stroke.

The front conveyor is fixed whilst the rear conveyor is adjusted by software to the board width.

There are two types of conveyor systems:

●

Over the Top Clamping (OTC)

●

All Purpose Clamping (APC)

Both conveyor systems have three stages allowing three boards in the printer at any one time. The

input auxiliary section can hold an incoming board until the print section is available. The print sec-

tion secures the board and lifts the board up to the stencil, ready for printing. The output auxiliary

section can hold a printed board until the downline machine is available.

4.1.9 Tooling Table Module

The tooling table module provides a stable base for the board support tooling and positions the

table at various heights during the print cycle.

4.1.9.1 Tooling

The role of the tooling is to support the board during the print stroke, to prevent print distortion

caused by flexing of the board as a result of the downward pressure of the squeegees. Several dif-

ferent types of tooling are available including vacuum and dedicated tooling.

4.1.9.2 Vacuum Tooling Port

There is a vacuum port built into the table top for dedicated tooling and vacuum boxes.
