6.2 Reference Run

The 6 and 12 C&P head has 3 axes Star, Z and DP and the X and Y axes for the Gantry. The Twin

head consist of two axes one Z axis for up and down and one D axis for rotation. Before you start

the production you must initialize all axes that the axis controller know their actual mechanical po-

sition.

General sequence 6

– This principle about the reference run is the same at DLM1 or 2 6 - or 12 nozzle C&P head.

– The reference run starts with the initialisation of all the head stepper motors. This allows then,

the head axis to reference by moving first to their zero pulses and then to their zero point cor-

rection values.

– For the Siplace HF machine both heads (C&Phead,Twin head) and gantrys reference at the

same time .

6.2.2 Initialize Valve Drive at Pick-up / Placement Position / Reject Position

The function of the stepper motor, with the aid of an eccentric movement, is to move the plunger

which will switch vacuum on and allow component to be picked. When placing the component the

plunger is switch again for nozzle closed, so that we have air kiss on the nozzle for placement.

When reject the component the plunger will switch air kiss on and allow component to be rejected.

After this we switch back on vacuum .

Fig. 6.2 - 2 Initialize valve drive at pick-up / placement / reject position

Key:

(3) Home position, initial position. Give way free for Star axis movement. Drawing show 2 possible

positions of the plunger

(4) 2a. is switching to vacuum, Vacuum value "Nozzle open"

2b. is switching to air kiss, Vacuum value "Nozzle closed"

(5) Counter position to initial position. Give way free for Star axis movement.

– The stepper motor of the valve drive is turned to the home position. The stepper motor runs

and the light barrier on the cam disk sets the end signal.

– Because of the special shape of the cam disk the stepper motor is able to recognize the home

position (1.).
