18.3.7. Gantry Thermal Mapping

The fiducial marks on the conveyer shall be taught at 3 points in order to compensate the

thermal deformation of the XY coordinate system due to the heat created by the friction of

the ball screw after operation of the machine.

Figure18.13 “Gantry Thermal Mapping” dialog box

1: Grid group

 <Gantry> combo box

Select the gantry for which the thermal mapping is to be performed.

 <Move> button

Move the fiducial camera of the corresponding gantry to the position of the fiducial

mark selected from the Grid group.

 <Get> button

Apply the coordinate value of the current position as the selected fiducial mark

position.

 <Enable Gantry Thermal Mapping> check box

Decides whether to carry out Gantry Thermal Mapping. When all the fiducials on the

transport rail are taught for Calibration, it will be checked automatically. To disable

the “Gantry Mapping”, remove the check from the check box.

 <Mapping Time Mode> group

Set the cycle by which the mapping is performed.

Auto: Automatically performs the mapping by the cycle already determined.

 Manual: Input the cycle into the edit box at the right and perform mapping for

every corresponding cycle manually.

 <Automatic Next> check box

Select this check box and click the <Next> button. Then the gantry thermal mapping is

performed automatically.

 <Manual> check box

Move the gantry to the designated position by using the teaching box and perform the

gantry mapping manually.

18.3.7.1. Procedure

The gantry mapping method is as follows.

1. Referring to the following figure, perform teaching of the position of fiducial mark 3

located on the upper surface of the conveyor.

2. Click the <Move> button to move the fiducial camera to the designated position.

3. Adjust the position of the fiducial camera by using the teaching box so that the center

of the cross hair displayed in the SMVision window matches with the center of the

fiducial mark # 3 that was already set on the conveyor.

4. Click the <Get> button to reflect the current coordinate.

5. Identically teach fiducial marks #1 and #3 in order as shown in the above figure.

6. Once the teaching of the fiducial marks at three points for Gantry 1F is completed, the

teaching of the fiducial marks at three points for Gantry 1R is performed. The teaching

is performed in the same manner for Gantry 1F.

7. If the teaching is completed properly, check the "Enable Thermal Mapping" and set

the Mapping Time Mode. When selecting the Mapping Time Mode manually, set the

time.
