5.1.19 CONVEYOR BELT WIDTH ADJUSTMENT

NOTE:

For machines up to and including

batch identity no. 3

the conveyor width is adjustment with the main

menu displayed (handwheel !).

This function allows you, when required, to adjust the conveyor to the PCB width required in the AutoCal

measuring sequence.

After the menu option has been selected, the following function bar appears on the screen:

Description of the function keys offered on the screen:

— "SLOW / FAST"

(toggle): to select the speed for the width adjustment. Preset: "fast".

— "CONVEYOR <-->"

"CONVEYOR ->--<-" =

to start the adjustment (<--> = increase, ->-<- = decrease).

— "STOP"

= to stop the adjustment process.

— "STEP OFF"

= to perform width adjustment in steps.

— "PCB --> EXIT"

= to convey the PCB to the output station, e.g. to check the adjusted width).

— "WIDTH IN MM"

= to enter the desired PCB width (see "Prerequisite" below).

—

"END"

= to return to the main menu.

➤ On machines with automatic width adjustment pay attention to the WORKAROUND → section 12.2

➤

Prerequisite

for the exact adjustment to the width entered (function key F 7) is that "PCB EDGE FIXED

TABLE" has already been determined.

➤ When adjusting the conveyor width, the PCB

must not

be placed above the light barrier as otherwise

width adjustment cannot be carried out.

• When function key F7 is selected, the following prompt is displayed on the screen:

PC-BOARD WIDTH [MM]

• Procedure: input the desired value (= PCB width used) → approach the movable table side → gantry mo-

ves to the appropriate, internally calculated width → width adjustment of the conveyor is started and is

stopped when the Bero on the movable table side is activated.

• If the Bero fails to be activated, the following

error message

is displayed:

CONVEYOR IS AT LIMIT SWITCH

•

Error correction:

Using the appropriate function key (see above) move the conveyor away from the li-

mit switch and correct the error (incorrect sensing distance / defective Bero).

• Subsequently, repeat the adjustment of the conveyor width.

5.1.20 AXES MOVEMENT MENU

This menu enables you, in the event of an error, to check the movement / positioning of individual axes and

perform the axis adjustment, if required.

After selecting the main menu option, a

submenu

is displayed (see Fig. 1.5) from which you can select the

appropriate axis. Thereafter the function menu of the selected axis is displayed.

The function menu of the Z-axis differs from that of the remaining axes in that it comprises an additional fun-

ction that can be selected (continuous run function with standstill control) as well as the value for the force

that can be edited, as displayed below.

➤ Pay attention to

section 2.3 "Safety Prompts

When Carrying Out the Axes Movement Menu.

•

After selecting the Z-axis the following

functions screen

is displayed:

—

The actual position is continuously updated during the performance of the functions for the Z-axis (or X,Y-

axis).

—

For the values Z_min and Z_max the values are displayed that are entered in the machine data for the mi-

nimum and maximum Z-traversing range. This applies also for X_ / Y_min. and X_ / Y_max.

—

For the continuous run of the Y-axis the left table side (Bero) is approached and the possible traversing

range is determined.

—

For the adjustment of an axis you require the documentation for the axis adjustment (adjustment instructions).

After selecting the Edit function the following Edit screen is displayed:

— Here, the parameters can be modified locally.

— The values for acceleration and deceleration can not be edited.

— The maximum possible value of the speed is taken from the machine data.

— The value range for the force is from 1 to 99.

— For the start and end positions only values within the traversing range, as entered in the machine data,

are possible.

•

Description of the Functional Sequences

—

EDIT: The values are changed in the editor of the continuous run function only temporarily. The origi-

nal MA data entries in the machine data remain unchanged. The AutoCal program uses the default va-

lues for all remaining functions.

—

POSIT.: The selected start position is approached on the basis of the selected parameters.

—

CONT. OP.: When this function is selected, the "START" label in the function key is replaced by

"STOP". The text labels of the other keys are deleted. All axes are made to travel back and forth be-

tween the two positions INITIAL POSITION and FINAL POSITION. Also here the selected parameters

are used. After every traversing operation a defined time span of 0.5 ms elapses which is fixed pro-

grammed in the software. Pressing the STOP button causes the continuous run to be terminated.

—

CONTINUOUS OPERATION WITH STAND STILL CHECK (only Z-axis): Here, the Z-axis travels in

downward direction by means of standstill control and deposits the steel nozzle on the previously loa-

ded PCB. Depositing the nozzle is to be confirmed by pressing <RETURN>. The continuous run with

standstill control starts and can be terminated at any time by pressing "STOP". After the termination,

the head always moves to the 0-count position.
