RISING TABLE MODULE - STYLE 2
OVERVIEW
28.2 Techncial Reference Manual Chapter Issue 3, Feb 18
The rising table moves up and down within the machine supporting the product
board, via the tooling, and accurately positions the height of the rails at several
different pre-determined heights during the print cycle. The rising table contains
the attachment points for the transport rails and the drive for the moving rear
rail, for more information refer to the Transport Rails chapter.
The rising table heights, determined by the software and referenced from the
home position, are as follows:
• Home Position
• Transport Height
• Vision Height
• Print Height
The rising table homes only when the machine initialises, this is achieved at
power up or when exiting diagnostics. Transport height is preset in the product
file allowing clearance for the board to clear the tooling whilst entering and
leaving the machine. Vision height brings the board into the camera focal length
for the vision system. The board is paused at this height whilst stencil alignment
is achieved. The rising table is taken up to print height for the board to be
printed.
The rising table also supports the remote board stop which is used for position-
ing large or heavy boards.
