3.6.8 Replacing the Lifting Table Unit Modular PCB Conveyor System

Service Manual SIPLACE X Series 167

► Loosen the screws (2) and (3), fastening the lifting table unit.

► Remove the cover on the conveyor conversion board and unplug the connection cable (4) from the

lifting table unit.

► Unplug the compressed air connection (5).

► Carefully lift the lifting table (6) off the locating pins.

Installation

► Check the lifting table speed and the functionality of the PCB clamping device, without the lifting table

plate.

► If necessary, readjust the values. ("5.4.8 Lifting Table Functions" [ ➙ 339])

► Carefully place the lifting table plate (1) onto the lifting table unit and tighten the fastening screws

diagonally, so that the lifting table plate does not stick.

► Check the lifting table speed once the lifting table plate has been installed.

CAUTION

Screw positions!

Do not loosen the screws directly next to item (2)! If you do, the lifting table mechanics will be

displaced which could lead to tension and increased wear.

CAUTION

Heavy machine part!

When removing the lifting table, remember it is heavy (17.5 kg).

CAUTION!

Deaerate the lifting table valve!

When using a SIPLACE X4I or any PCB conveyors with

a bumper length of 35 mm, the lifting table valve inlet 2

must be de-aerated before reassembly. This ensures

free movement of the mechanism.

The lifting table mechanism can be raised during assem-

bly, to prevent distortion of the lifting table plate.

► Lift the lifting table unit (6) into the machine and posi-

tion it on the locating pins.

► Screw in the fastening screws (2) and (3).

► Reconnect to the electrical (4) and compressed air

(5) systems.

NOTICE!

Run the tables under the mechanics so that these are not

damaged when you move the lifting table upwards.

3.6.9 Replacing the Lifting Table Stabilizer (Stabilizer Unit) [00358684-xx]

Replacing the Lifting Table Stabilizer (Stabilizer Unit) [00358684-xx]

Overview

Tools and equipment required

▪ Torque wrench with plug-in ratchet [00386175-xx]

▪ Plug-in wrench 16 mm [00386177-xx]

Removal

1. Actuator

2. Locknut

3. Fastening screws

4. Handle

5. Stabilizer [00358684-xx]

The stabilizer enables the lifting table to be moved gently

upwards. It prevents the PCBs from being clamped in

with too much impact.

The stabilizer consists of the shock absorber [00367737-

xx] and the damping block [00367782-xx].

► Move the PCB conveyor to the position which gives

you best access to the lifting table.

► Move the Y gantries into the area outside the PCB

conveyor.

► Switch off the machine and secure it to prevent unau-

thorized reactivation.

► Loosen the screws fastening the lifting table plate and

remove the lifting table plate from the lifting table unit.

► Loosen the two screws (3) holding the stabilizer (5).

► Undo the locknut (2) and take the stabilizer by its han-

dle (4), twisting it out of the mounting block.

Service Manual SIPLACE X Series 169

Installation and adjustment

► Insert and twist the new stabilizer (5) until the plunger

just touches the actuator (1), so that the lifting table

can be gently moved upwards.

► Using the torque wrench:

Secure this position with the locknut (2) tightened to

8Nm.

► Check whether the stabilizer has been fixed onto the

mounting block with the locknut and that the stabilizer

plunger has a gap of approx. 0.1 mm to the actuator

(gap in untriggered mode). In this default setting, the

lifting table should move up gently.

► If this is not the case, loosen the locknut and turn the

stabilizer approx. one rotation into the mounting

block.

► Fit the lifting table plate.

► Start SITEST and move the lifting table up.

► The lifting table should move up gently i.e. you should

not hear the PCB clamping device audibly locking

into place and no clamping device error messages

should be issued.

► Check the speed of the lifting table cylinder and cor-

rect where necessary.
