First play
I want to create a self guided device for meassuring the poliurethane bead in a winscreen glass before the robot inserts it to the car.
the operator can meassure 4 points per glass side to check if the bead is well located.
this meassurement ican be done before the poliurethane is cured, with out contact. Normal method use a calliper to meassure the bead position once it is cured. The glass must wait 24h before it can be meassure to avoid the bead could be damaged.
with this method the glass can belongs to a production car, it can be measured and inserted again.
due to the TFT has a SD car, the data can be stored on it for data tracking as a control process.
