5 Reference Run

5.1 Reference Run (D-Series)

The placement machine reference run guaranties the correct function for placement in the station SW.

This is where the reference runs for the C&P head and for the gantry are described. A separate chapter

describes the reference run for the P&P module, performed parallel to that for the C&P head.

5.1.1 Overview

The reference run is divided into 4 main steps. Module reference runs for the WPC or for a 2nd

placement head per gantry are not listed at this stage.

1. Conveyor system reference run

This activates the unoccupied (not occupied with a PCB) conveyors.

(in older SW versions, this function can also be performed to conclude the reference run.)

2. Axis reference run

This is divided into:

A.) the head axis reference run and

B.) the gantry axis reference run.

The gantry head axes are started at the same time. As many functions as possible are performed at

the same time.

3. Vacuum reference run

The

A.) vacuum values "open" and "closed" for placement are determined and

B.) all segments in the DP stations are rotated into their 0 degrees positions.

4. Height Reference Run

This function tests the length of the segment nozzles and of the heads in a placement area, on the

top surface of a conveyor side.

These are described and explained in detail below. Machine type or configuration-related extensions or

deviations are explained in separate texts to prevent confusion.

5.1.2 Conveyor Reference Run

The conveyor reference run tests the function of the conveyor belts. This requires the relevant conveyor

belt to be empty i.e. to be free of boards (PCB). If one of the PCB sensors detects a board, this conveyor

belt will not be activated and this board will be transported to the output conveyor of the placement

station, at the end of the complete reference run.

5.1.3 Axis Reference Run

5.1.3.1 Head Axis Reference Run

The C&P6/12 placement heads need to be prepared for the axis reference run.

Sequence:

X Initialize the stepping motor as soon as you have switched on the machine:

X Press START button

This also switches the control voltages on.

X Preparing the star axis reference run

The following steps are performed:

– Upwards movement of Z-axis to top end stopper.

– Downwards movement to Z position (30 digits) with reduced force for free star movement.

5-1: Initializing stepping motor at DP-station (1)

Legend

1. Home position DP drive around 1 mm away

from segment

 The DP station has swiveled approx. 1 mm

away from the segment.

5-2: Initializing valve positioning drive at pickup/placement and reject position

Legend

 1. Home position, initial position. Give way free

for Star axis movement.

 3. Counter position to initial position. Give way

free for Star axis movement.

– The stepping motor of the valve

positioning drive is turned to the home

position. The stepping motor runs and the

light barrier on the cam disk sets the end

signal.

– Because of the special shape of the cam

disk, the stepping motor is able to

recognize the home position (1) or (3).

 The valve positioning drives have positioned

the drive ball bearings in the valve plunger so

that star rotation without malfunction is

possible.
