Preferably, before the step one, the method further comprises the preparation steps of:
the tray is jacked up through the cylinder, so that the tray is ready for receiving the dial with a flat surface.
Preferably, the preparation method further comprises the following steps before the preparation step:
and reading the RFID label on the tray through an RFID reader-writer, and starting a preparation step after reading.
The invention has the beneficial effects that:
this application measures the distance that laser reachd at least three different positions on the dial plate through laser rangefinder sensor, will measure at least three distance and get the average value, compare with average value and setting value and every distance that will obtain and set for upper and lower limit value and compare, if satisfy the requirement, then judge dial plate surface roughness, if unsatisfied the requirement, then judge dial plate surface unevenness, at least three distance and dial plate roughness that this application measured are for the later press fitting use.
This application can highly inspect the product after the dial plate assembly, when the height out of tolerance, then do not carry out operation on next step, extra loss can not appear. The product quality and the production efficiency are improved.
