Precaution when the nozzle vacuum pad for support pins is replaced
If the vacuum pad is not inserted all the way, it may reduce the accuracy of the support pin arrangement
position, resulting in support pin replacement error. When the vacuum pad is replaced, make sure to check
the insertion condition of the vacuum pad. Install the vacuum pad as shown below so that there is no gap.
Gap
The insertion condition of the vacuum pad can be checked from the vacuum side. Make sure to check if the
vacuum pad is installed all the way to the end of the metal flange.
