Insertion of Recovery Sequence

If a vision processing error occurs or there are no parts and the machine is set to carry

out a recovery operation, the recovery sequence will be inserted either 6 or 15 sequences

later.

If an error occurs between station 17 ~ 2 then recovery processing takes place at station 2

(this is done 6 sequences later however, this recovery processing does not include such

things as parts being discarded due to an emergency stop).

When an error occurs between station 3 ~ 10, recovery processing for such things as the

discarding of parts due to an emergency stop takes place at station 11 (15 sequences

later).

1.4 Nozzle Related Functions

1.4.1 Nozzle Check Function

This function checks the production program to confirm that the appropriate nozzle is

installed in each holder. This is done by performing a check on the nozzle diameter and

the back light disk size.

If a program has been transmitted to the foreground, then once program changeover has

been completed the Nozzle Check function is carried out when automatic operation

begins. If the nozzles installed in the previous production program have the same nozzle

diameter and back light disk size as the nozzles set to be used in the current production

program then no check is performed. If either the nozzle diameter or the back light disk

size are different then a check is performed. A check does not occur, for example, if a

white nozzle is replaced with a black nozzle, regardless of the nozzle size, etc.

It is necessary to set the appropriate Proper data item to enable this function. Make the

setting in the following manner:

[Proper]

136. Nozzle Check SW: This Proper data item determines whether or not the function

will be carried out.

(Example) 136. Nozzle Check SW Yes No

Yes: Mandatory nozzle check occurs

No: Mandatory nozzle check does not occur

When the Nozzle Check function is enabled a display like the one below will appear.

SET: Press this key to set the selected nozzle.

▲: Press this key to move the cursor up.

▼: Press this key to move the cursor down.

RETURN: Press this key to enter the nozzle center of rotation measurement command.

"UNSET" is displayed in red and "SET" is displayed in green.

1.4.2 Nozzle Center Measurement

In order to achieve high placing accuracy, the machine stores data on the center of

rotation, the amount of bend and other such data for each nozzle. The measurement of

these compensation data is called nozzle center measurement. Nozzle center

measurement is an indispensable part of being able to carry out highly accurate

placement.

This chapter provides an explanation of the nozzle center measurement.

(1) An Explanation of Nozzle Center Measurement

Nozzle center measurement carries out a measurement of the holder's rotation center.

The amount of bend in the nozzle, the nozzle tip diameter and the brightness of the

nozzle back light disk are also measured at the same time.

The distance from the rotation center to the nozzle tip is calculated. The nozzle bend is

compared to the amount of allowable bend (bend tolerance) and a decision is made.

When the nozzle is rotated 180° this yields the maximum amplitude of the nozzle tip and

thus the maximum amount of bend tolerance.

The nozzle center measurement is carried out twice on a single nozzle. The first

measurement looks at the current nozzle tip position. The second measure of the nozzle

tip position is carried out after the nozzle has been rotated 180°. During this second

measurement the maximum amplitude of the nozzle tip, the center and the amount of

nozzle bend are calculated.

Image processing for a single nozzle is carried out using both the wide view camera and

the narrow view camera since the camera resolution, field of vision and other such

variables are different.

Note: The narrow view camera (in effect the image is magnified by this camera) has a small area

image and is not used to perform nozzle center measurement on nozzles with a diameter

2.0 mm or greater.
