Setting Tray Library Data (2)
This method applies to trays not positioned against the positioning blocks of the pallet. In this
case, you must notify the system of the offset of the tray.
First, enter [Count X] and [Count Y] settings manually. Then perform teach entry for other
settings (Tool>Teach>TrayTeach).
Action:
Type in [Count X] and [Count Y] settings so they correspond to the location of the third teach
point. In the below example: [Count X]=4, [Count Y]=3.
① Set the tray to a pallet. Set the pallet to MX-40. (See Chapter 7.)
② Open the Board Data dialog box (Program>File>BoardData) and enter the board size
correctly. (for the case of MX-20 and MXR)
③ Click Library>Pallet Library to open the pallet library editor.
④ Click the X Offset or Y Offset field of the pallet. ([X Offset] and [Y Offset] settings must be
entered beforehand.)
⑤ Click Tool>Teach to open the Teach dialog box.
When choosing <Move Pallet> button in the Teach dialog box, do not stick head, hands,
or other parts of the body inside the mounter. Serious injury can result. Also make sure
non-operators are a safe distance from the machine.
⑥ In [Tray Teach] tab, under [Unit], select a tray feeder. Under [Shuttle Position], select a
pallet stop position. When [Unit] is "MXR", select "Front". When [Unit] is “MX-RT1”,
select “Front” or “Rear” (either will do).
The steps 7 through 8 stated below apply only to MX-40, MX-20, and MXR. As for MX-ST2,
manually set the pallet to the front or rear pickup position.
⑦ Under [Pallet No.], enter the pallet number.
⑧ Under [Mode], click <Out> button. Then click <Move Pallet> button. The specified pallet
moves into the mounter.
⑨ Click <Trace> button. The main teach camera moves toward above the front right corner
of the tray.
⑩ Open the tray library editor. Click the line to edit. Click <User Origin> button in the Teach
dialog box.
Then follow the steps 7 through the end of Setting Tray Library Data (1) in the previous section.
Tray Trace Feature
This feature allows the specified head to move to the specified tray component.
Select a line to trace in the tray library editor. Then open the Teach dialog box. Then specify the
tray feeder to [Unit], pallet stop position to [Shuttle Position], pallet number to [Pallet No.], and
component position to [X Pos.] and [Y Pos.]. Click <Trace> button to execute.
Note: Manual entry of the tray library data using ready-to-use database or actual measurements is
also available.
