⑥ When the nozzle touches the component, the vacuum pressure rises. At the same time, the

motion of the nozzle stops and the following dialog box appears.

When you click the <Yes> button, the Z coordinate is determined as the component height

and registered in the tray data. After this process, the nozzle moves up automatically.

Teaching the component height has the risk of collision of the nozzle against the component.

Therefore it is recommended to measure the component thickness with a caliper and enter the

thickness in the Component Height manually.

When you start the surface teach, first, the nozzle travels to the coordinates of the [X Pos.] and

the [Y Pos.]. Then the nozzle moves down to the height of the [Start Z] and starts the

automatic-component-height teaching.

Before performing the surface teach, be sure that a component exists in the tray pocket where

the component height is measured. Otherwise the bottom of the empty tray would be

determined as the component height. It may result in nozzle and head damage.

Do not make the [Start Z] value too low. Otherwise the nozzle may hit the component surface

and may result in nozzle and head damage.

Note: Initial value of the [Start Z] is 20mm.

If you start the surface teach at this height, the process takes more than 10 minutes. Start

moving from the height close to the component surface. (See step ③.)

Note: Lighter components are not appropriate for this automatic-component-height teaching because

they may be sucked up before the nozzle reaches to the component surface. It may result in

determining higher component height than the actual height. For such lighter components,

manually measure the thickness with a caliper and enter it in the Component Height.

 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.

5-2-4 Tray Orientation Check

The tray orientation check function finds the orientation of component trays and prevents from

setting trays in wrong orientation. The main teach camera captures an indexed part (chamfered

corner) of a component tray and judges the tray orientation set on the tray feeder.

 Application

The tray orientation check function is available for the following tray feeders.

 Setting

Menu: System > Tray Library

Action:

① The way of the bad-mark image-capture is applied to this tray orientation check function.

In the [Orientation Check] column, select the logics to find tray reference corners, ”OK:

Found Ref. Corner” or “OK: Not found Ref. Corner”.

Usually Use ”OK: Found Ref. Corner”.

② Click a [Ref. Corner X] or a [Ref. Corner Y] cell of the tray data to edit. The teach window

below appears.

③ Make sure the tray model in the [Unit] and the pallet No. are correct. Pull out the pallet.

Then teach the indexed part (chamfered corner) and click the [Teach Coordinates] to enter

the coordinates.

Teach the indexed part (chamfered

corner) and determine the coordinates.
