Board Measurement

This section introduces how to measure the width, length, and thickness of a board.

The operations below are available in the Process screen if not indicated otherwise.

Measure Board Width

This function measures board width with the loading of the side leaning mechanism. After the loading reaches the set value, the side leaning mechanism stops movement and reads the coordinates. The measured width needs to be compared with the board actual width.

Procedures:

  1. In the board and stigma list area, check Sidelean in the upper right corner to enable the side leaning mechanism.

  2. In the Work List area, check WidthM to enable board width measurement.

  3. In the menu bar, go to System > Width measurement setting.

  4. In the Plate width measurement parameter setting dialog box, set the following parameters:

    Parameter Description
    Backing plate speed The speed when moving toward the board from the measuring point.
    Distance from the point The distance between the measuring point and the board.
    Measure the distance The distance between the measuring axis mechanical origin and the clamp (for position calculation).
    Maximum distance The maximum distance that the measuring axis can move.
    Measurement end fallback The withdrawal distance of the side leaning mechanism after the measurement is complete.
    Width tolerance The tolerance allowed for width measurement.
    Stop load rate The side leaning mechanism stops when the load rate reaches this value. Set it to a value as large as possible to avoid stopping in middle of normal movement.
    Starting load rate The measurement starts when the side leaning mechanism reaches the board and the load rate reaches this value.
    Traveling load rate The load rate when the side leaning mechanism is in middle of movement.
    Maintain load rate The load rate that needs to be kept after side leaning is complete.

  5. Click Save to save changes.

  6. Use one of the following methods to start measuring:

    • Press the F9 key.
    • In the machining operation bar, click .
    • In the menu bar, go to Operate > Cycle Start.

  7. In the menu bar, go to System > Width measurement setting. In the Plate width measurement parameter setting dialog box, check the measurement result.

  8. Compare the measuring result with the actual board width and see if the measuring error is within the tolerance:

    • Yes: Measurement is successful.
    • No: Repeat the steps above to measure again.

Measure Board Length

The opto-electric switch is used to calculate the board length by measuring the presence of signals, which needs to be compared with the board actual length.

Procedures:

  1. In the board and stigma list area, check Sidelean in the upper right corner to enable the side leaning mechanism.

  2. In the Work List area, check LengthM to enable board length measurement.

  3. In the menu bar, go to System > Length measurement setting.

  4. In the Plate length measurement parameter setting dialog box, set the following parameters:

    Parameter Description
    Dis between pos and pho The distance between the positioning cylinder and the opto-electric signal in the clamp movement direction.
    Compensation distance Compensation during movement to ensure the normal entry into and exit from the signal area of the board.
    Length tolerance Tolerance allowed during length measurement
    Spot error compensation Compensation for the measurement result if there are errors.

  5. Use one of the following methods to start measuring:

    • Press the F9 key.
    • In the machining operation bar, click .
    • In the menu bar, go to Operate > Cycle Start.

  6. In the menu bar, go to System > Length measurement setting. In the Plate length measurement parameter setting dialog box, check the measurement result.

  7. Compare the measuring result with the actual board length and see if the measuring error is within the tolerance:

    • Yes: Measurement is successful.
    • No: Repeat the steps above to measure again.

Measure Board Thickness

Magnetic grating ruler is used to measure the height difference when the clamp is released and clamped. The measured thickness needs to be compared with the actual board thickness.

Procedures:

  1. In the board and stigma list area, check Sidelean in the upper right corner to enable the side leaning mechanism.

  2. In the Work List area, check ThickM to enable board thickness measurement.

  3. In the menu bar, go to System > Thickness measurement setting.

  4. In the Plate thickness measurement parameter setting dialog box, set the following parameters:

    Parameter Description
    Clamp release H The maximum height between the clamp internal sides when the clamp is released.
    Clamp delay Delay before measurement.
    Tolerance The tolerance allowed during thickness measurement.

  5. Use one of the following methods to start measuring:

    • Press the F9 key.
    • In the machining operation bar, click .
    • In the menu bar, go to Operate > Cycle Start.

  6. In the menu bar, go to System > Thickness measurement setting. In the Plate thickness measurement parameter setting dialog box, check the measurement result.

  7. Compare the measuring result with the actual board thickness and see if the measuring error is within the tolerance:

    • Yes: Measurement is successful.
    • No: Repeat the steps above to measure again.
