1.4.3 Automatic Nozzle Selection

The machine often changes nozzle types according to the type of board being produced.

The nozzle data used for this purpose is specified in a nozzle assignment table.

The machine selects the most appropriate nozzle for placement based on the data related

to nozzles in Part Data and on the data in the nozzle assignment table.

Data necessary for determining nozzle type

• Nozzle diameter data in the nozzle assignment table

• Nozzle back light disk size data in the nozzle assignment table

• Maximum nozzle diameter and selected nozzle diameter in Part Data

• Minimum back light disk size in Part Data

(1) Nozzle Diameter Data

The diameter of the nozzle that will be attached to each holder for carrying out

production is set in the nozzle assignment table.

Refer to 1.4.2 “Nozzle Center Measurement” of this chapter for information concerning

the procedure for specifying nozzle diameter data.

Caution: For a 0.4 mm nozzle, use nozzle Nos. 2, 3, 4, 5 or 6.

(2) Nozzle Back Light Disk Size Data

The size of the nozzle back light disk of the nozzle attached to each holder is set in the

nozzle assignment table.

Refer to 1.4.2 “Nozzle Center Measurement” of this chapter for information concerning

the procedure for specifying nozzle back light disk size data.

(3) Maximum Nozzle Diameter and Selected Nozzle Diameter

There are two fields in Part Data which are used in the automatic selection routine of the

machine. They appear under Carrying_data as follows.

PART DATA

Carrying_data

17. Nozzle_size_max. : Defines the maximum diameter of the nozzle which can be used

in placing the part

Example) 17. Nozzle_size_max 1.3

36. Nozzle_size_CP6 : Defines the specific nozzle diameter when a specific nozzle size

should be used

Example) 36. Nozzle_size_CP6 1.0

Normally the optimal nozzle for placement is automatically selected from the nozzle

assignment table and the maximum nozzle size data (Nozzle_size_max).

However, if a specific nozzle is to be set, then and only then should the select nozzle size

data “Nozzle_size_CP6” be input.

Part 2 Chapter 1 Basic Operation

Edition 1.1 2-1-31 CP643E System Reference

The largest permissible nozzle (a nozzle which does not exceed the “Nozzle Size Max”

item in the Environment Data) is automatically selected from those registered in the

Nozzle Data. Therefore, when no particular nozzle is to be specified, both the “Nozzle

Size Max” and “Nozzle Size Min” settings must be specified.

1. Start the VPD.

2. Open the “Part Type Data” in the relevant part data.

3. Click the [Environment] button to open the Environment Data, then select “CP643” at

the M/C Type item.

4. Enter the nozzle sizes at the [Nozzle] - [Nozzle size] item. Enter the maximum nozzle

size in “Max” item when using automatic nozzle selection function. No entry is

required for “Min” item. Enter the same values in both “Max” and “Min” items when

specifying the nozzle to pickup the part.

Note: If a nozzle matching the nozzle specified here has not been specified in the nozzle

assignment table, this will be interpreted as the nozzle not being set on the machine and

thus the data check of the program which includes this part will result in an error.

(4) Minimum Disk Size

This data item is used to specify the minimum size of the back light disk.

PART DATA

Carrying_data

16. Back_light_min. : Input the smallest disk size to be handled by vision processing in

1 mm increments.

Example) 16. Back_light_min. 12

1. Start the VPD.

2. Open the “Part Type Data” in the relevant part data.

3. Click the [Environment] button to open the Environment Data, then select “CP643” at

the M/C Type item.

4. At the [Camera] - [Back Light Min] item, enter (in mm units) the minimum nozzle back

light disk diameter permitted for normal vision processing.

Caution: The value entered at the Back_light_min (for MCS) or Back Light Min (for F4G) item must

not exceed the Back_light_size” (for MCS) or Back Light Diameter (for F4G) setting in the

nozzle assignment table.
