(5) Parts of the Board Loader System The CP-643E sequencer loader differs from the “conveyor to conveyor” flow of the standard sequencer loader. On the CP-643E the flow is on a “receive and transfer” basis using carriers…

• STN 12: Reverse Fθ (Fine Reverse Theta)

The theta rotation angle that was performed at ST 10 is reversed. (If there

was no Pθ rotation at ST 3, at this point, the nozzle is returned to the original

position.)

Nozzle origin search is performed for all nozzle clutches when automatic

operation begins after the power is turned on, or after an emergency stop or

other alarms. (Nozzle Origin Search Sensor: Refer to Part 2, Chapter 1, 1.4.7

“Nozzle Origin Search Sensor”.)

• STN 13: Reverse Pθ (Pre Reverse Theta)

The theta rotation angle that was performed at ST 3 is reversed (At this point,

the nozzle has returned to the original position).

• STN 14: Head A detection

Head A detection is performed.

• STN 15: Confirm Nozzle Clutch Origin Position

At this station the origin position of the head is confirmed. Heads that are

not at the origin position will be skipped and returned to the origin position

next revolution at station 12.

• STN 16: Reject Parts

Parts deemed defective by the vision system and/or outside dimensional

tolerances are dumped at this station.

• STN 17: Detect Nozzle Type

Detects the selected nozzle type (No.1 to No.6) prior to nozzle changes.

• STN 18: Nozzle Change

The nozzle that will be used for the next part pick-up is selected.

• STN 19: Nozzle Change Check

Verifies that the correct nozzle is being used following a nozzle change. If

nozzle change error occurs, the erroneous head will be stopped at this

position.

• STN 20: No Function

(5) Parts of the Board Loader System

The CP-643E sequencer loader differs from the “conveyor to conveyor” flow of the

standard sequencer loader. On the CP-643E the flow is on a “receive and transfer” basis

using carriers. As shown in the figure below the board loading system is divided into

three conveyors and two carriers. The direction of board transfer is as follows, from the

in-conveyor, in-carrier, main conveyor, out-carrier, to the out-conveyor. Two boards can

be simultaneously transported on each respective conveyor and carrier (For 2-board

production programs).

In-carrier: Receives boards from the in-conveyor and transfers boards to the main

conveyor.

Out-carrier: Receives boards from the main conveyor and transfers boards to the out-

conveyor.

In the case of a 2-board production program, the second board stops at the middle

stopper position on the in-conveyor thereby creating a gap between it and the first board.

The boards are transferred to the in-carrier and main conveyor in this status.

If the middle stopper position on the in-conveyor is not set correctly this will have a

negative effect on mark acquisition and part placement on the second board.

Direction of board flow →

Cautions:

1. When the main conveyor is to be unclamped, perform the unclamping operation at either

the loading or unloading position. If the XY-table is below the dropped parts tray and the

main conveyor is unclamped, there is a danger of the dropped parts tray interfering with the

clamping jaws.

2: When the in-carrier or out-carrier is advanced or retracted using an I/O operation, the

operation should be carried out with the carrier clamping jaws in the closed status.

1.1.3 Changing the Original Table

The original device table, the table which is used first, is selected automatically when a

new production program or table mode is selected. The conditions under which the

original table will change are listed below.

(1) Change Due to Change of Production Program

The original table is determined according to the table mode when the new production

program is selected. On-screen display content is shown in parentheses.

• Device Change Mode (2A1A) and Changeover Mode (2B1A/2A1B)

The original table changes depending on the setting in the production program as

explained below.

[Program] Machine_data, 37. Original_table (Non, Table1, Table2)

Non: The table other than the table used until now is the original table. If table 1

had been used, table 2 will be the original table, and vice versa.

Table1: When the program has been changed and foreground transmission has been

carried out table 1 will be the original table.

Table2: When the program has been changed and foreground transmission has been

carried out table 2 will be the original table.

When Original_table is specified and many programs have used the same devices, then

time can be saved by not having to change feeder positions, or use commands to change

the original table.

Selected at the Table_Mode section of the “CCIMF Generate” item which displays when

programs are transmitted to the machine.

• Joint Mode (JOINT)

There is no original table.
