2.4 Sequence of Retrofitting 04/2000 Issue

Å If a movable component changeover table has to be connected, now turn the compressed air

back on at the main switch of the machine’s compressed air unit.

Connect the movable component changeover table.

Å Where applicable, use a pallet truck to move the (non-movable) component changeover table

back into the machine.

Å Where appropriate, set up component table 1 or 2 as specified under "Setup".

If applicable, carry out the set-up of the component table, as scheduled in the "Setting Up".

Å Where applicable, move the WPC into the machine.

Å If this hasn’t been done already, turn the compressed air back on at the main switch on the

machine’s compressed air unit.

Å Connect the machine to the mains and turn on the machine.

For the time being the control remains OFF.

Å Turn on the compressed air and the control.

Å Carry out the reference run. After the reference run, adjust the width of the PCB conveyor to

the width of the adjustment plate (or a suitable PCB).

Å Place the adjustment plate of adequate length (see Section 2.3.3) in the PCB conveyor such

that one-half of the plate is in the adjusted area, the other in the area to be adjusted.

Å Push the guide rail to be adjusted against the adjustment plate such that a clearance exists

that is small but sufficient for satisfactory transport (< 0.2 mm in terms of the PCB’s largest di-

mension).

the guide rail(s) in this position.

Å Manually push the adjustment plate through the entire PCB conveyor and make certain that it

moves easily and without resistance to the next conveyor and to the conveyor of the preceding/

following machine.

Å If necessary, align the guide rail(s) appropriately once more.

Å Remove all tools, etc., from the working area of the machine.

Å Load the SITEST program and calculate the position of the nozzle changer.

Å Check the input signal (0 -> 1) of the proximity switch(es) and the output signal for the pertinent

solenoid valve of the ceramic substrate centering unit.

Å Make certain that the pilot LED on the inductive proximity switch lights up when

"Centering unit opened to max.".

In the event of an error, make certain the plug-and-socket connection is securely seated on the

proximity switch. In addition, check the operating distance and, where appropriate, the plug-

and-socket connection on the conversion PCB of the PCB conveyor control.

Å Exit the SITEST program.

Å Start the station software and use the substrate test run (function in the menu "Ceramic sub-

strate centering unit" to make certain that the lifting slide of the centering unit does not bounce

during opening and does not open too slowly, i.e., no error message is output:

- If it opens too slowly, the proximity switch signal turns to 1 but does so too late.

- If it bounces, the proximity switch becomes free again (signal 1 -> 0 -> 1).

Å In the event of an error, correct the setting of the throttle valve for the opening movement ap-

propriately (see Fig. 2.4.7 -> 7).

Å Remove all of the tools, etc., and start the placlement sequence.

– Allen wrenches size 2.5 and 3

– Cross-slotted screwdriver size 1

– Adjustment plate or suitable PCB (see Section 2.3.3)

NOTE:

All of the steps described below are required for final reinstallation.

Only the following steps described below in detail are required for a mere temporary centering of

PCBs:

- Install the holddown brackets on the holddowns,

- Stow the proximity switch cable and pneumatic hose in the cable pit,

- Remove the "Slide unit, X-direction)",

- Slight increase in the Y-clearance of the PCB in the conveyor so that the Y-centering unit

has no effect due to the thrust-piece holder on the swivelling lever (see Fig. 2.4.2). 

Å The holddowns from the retrofit kit of the ceramic substrate centering unit are left installed..

Å Install the connecting rails (see Fig. 2.4.3 -> 14, 15) from the retrofit kit of the ceramic substrate

centering unit on the existing holddowns (6 cross-slotted screws M3 for each).

2.5 Reinstallation on PCB Centering Unit 04/2000 Issue

Å On the movable conveyor side, remove:

Å the rocker actuator (see Fig. 2.4.2 -> 6) from the holddown of the stationary conveyor side

(loosen 4 countersunk screws) and

Å the substrate guides (rail, thrust-piece holder and the "Guide, short": see Fig. 2.4.2 -> 5, 7,

8).

Å On the stationary conveyor side, remove the (substrate) "Guide rail, RH" (4 socket hex head

cap screws M3).

Å Place the 2 PCB rails (roller rails) on the stationary and movable conveyor side (Fig. 2.4.1 ->

6) and fasten them with the screws previously removed. Do not tighten the screws completely

yet.

Å Align the PCB guides with the aid of the adjustment plate that you push manually through the

conveyor, in parallel and in alignment inside the conveyor and to the next conveyor. Use

screws to fasten the PCB guides in the adjusted position.

Å Dismantle the "Slide unit, X-direction" from the lifting table (see Fig. 2.4.7). To do this, proceed

in the reverse sequence to that described for installation in Section 2.4.7.

Å Dismantle the lifting table plate (see Section 2.4.2). Loosen the pertinent cable ties and run the

free end of the proximity switch cable and the pneumatic hose back into the cable pit. Re-install

the lifting table plate.

Å Check that the PCB is conveyed satisfactorily in an analog manner to that described in Section

2.4.13 and, if applicable, correct the adjustment of the PCB guide rails.
