Layout
The press is a four-axis servo controlled machine. The pressing head moves 94 mm [3.70 in.] in the Z direction
at speeds up to 45 mm [1.8 in.] per second. The press head assembly is driven by linear servo motors from
side to side 914 mm [36 in.] and front to back 762 mm [30 in.] at a velocity of 1 m [39.4 in.] per second. The
PCB remains stationary on the support fixture. The fixture support table has a grid of dowel and threaded holes
used for locating and mounting PCB support fixtures. The center of the press head is calibrated to the first
dowel hole (lower-left) of the fixture support table (Machine 0,0). Once a fixture is located and fastened to the
fixture support table, the board is positioned on its fixture using tooling pins in the fixture. This establishes the
relationship to the fixture and therefore the exact location of the component coordinates on the PCB.
Each axis is controlled by a servo controller. Each motor includes a linear encoder.
The electrical controls are located in cabinets on the front and rear of the machine. The high voltage, servo
amplifier, DC power supplies, digital I/O and air valves are located in the rear chassis and the computer is
located in the front.
The pressing tools are stored in the tool rack directly behind the fixture support table assembly. The tool holder
is a static assembly for holding the tools. A Tool ID system is incorporated in the tool rack to manage the
presence and position of each tool. The press head will pick and place from the tool rack automatically as
required.

SAFETY
The CAP is designed to comply with the latest safety standards.
The operator is protected from pinch points and flying debris by proper and reasonable use of guarding
and interlocking.
Operators have ready access to an E-stop button. E-stops are unguarded, mushroom red operator
maintained twist/pull to reset with yellow background.
The Display screen displays all pertinent, real-time status information to the user. Additionally, standard
work commands are displayed on this screen.
The Maintenance screen (I/O) indicates the real-time status of all input devices and handshaking signals.
All output devices are controllable from this menu.
The Setup screen is password protected. All changeable system parameters are edited and viewed from
this screen.
Removable panels are removable with a standard hex key. Doors guarding hazards are included in an
interlocked safety circuit.
Electrical cabinet doors are lockable and labeled. All locks are keyed the same. See Figure 2.
