9.23 Definition of Additional Programming Features

Dot Point – Feed on Delay

In the distance parameter screen, the Feed on Delay should only be used to set the dispensing time for a dot.

Circular – Start Point Definition

Program Step-Through

A simulated run can be performed within the points list, anytime throughout the program. Use the up/down

jog keys to select where in the program the run is to be started. All co-ordinates will move at their

programed speeds. To switch between Simu X and Simu √ press

By pressing the robot will move to the next location and waiti until is press again.

In the Graphic Parameter screen, whilst inputting circle dimensions, the Start Points are as follows, in relation the

centre of the circle.

Simu √ Mode (wet run)

This mode will move to locations, whilst dispensing, so the operator can verify the

position, speed and dispense quality of the co-ordinates. Editing can be performed by

pressing on a selected line.

9.24 Line Dispensing Adjustments

9.24.1 Valve Feed On Delay - Lines

Usually, when a dispensing valve has been stationary for a period of time, for example at the beginning of a

dispensing program, there is a requirement for the initial dispensing to have a delay applied. This delay is usually

small, such as 50-100ms, which allows the fluid to flow and adhere to the correct position at the start of the pattern.

If no delay is applied, to the first dispensing location, the dispensing will be smaller than the rest or the start of the

line will be without adhesive.

Example of line with and without feed on delay:

From the Line Start screen:

Press

To go to the Points Parameters

screen.

Press

Select an available Feed

function, 1-5.

Press

Up to 5 Feed On delay or 5 Feed Off delay times can be set per program. Valve Feed Off Delay is the time the robot

will stay at the end of the dispensing location before moving to the next dispensing position. No fluid will be dispensed

during to the Feed Off time period. Note that dots use a feed slot and could conflict will line start delay if the same

slot is chosen for a dot and a line.

Press 2, to go to the Teach

Parameters screen.

Input the Feed On delay

Press until the Line

Start screen is reached.

starts the cycle.

Feed on delay, for a dot, sets the dot dispensing time. Up to 5 dots sizes (set by time) can be inputted per program.

Feed Off delay times can be set also. Valve Feed Off Delay is the time the robot will stay at the end of the dispensing

location before moving to the next dispensing position. No fluid will be dispensed during the Feed Off time period.

(Teach Parameters)

Press to select

an available “Feed On”

function: 1-5. For a new

program all 5 functions are

available.

Press

Repeat the process for

additional dots, either

selecting the same Feed On

function or selecting a new

one and inputting a different

time.

It is common, when dispensing dots, to see that the first few dots, of a new program, are smaller than the rest, if all

dots are programmed with the same dispensing time. This is due to the fluid being stationary, within the syringe or

pressure tank, whilst the valve is idle. The above process can be used to program the few dots slightly longer in time

to compensate but it is also common practice to dispense 2-3 test dots somewhere outside of the working area, to get

the fluid moving at a normal pace.

Dots 1 -3 require more dispensing time (Feed ON

Delay) to achieve the same volume as the other dots,

in the program.
