Abstract:
A test machine comprising a device for adjusting the conveying means for a printed circuit board to be tested, on the basis of the width of a printed circuit board (20), said conveying means being supported by parallel rails (110, 111) disposed in a test module or station (1) of the machine and being moveable toward and away from each other, characterized in that associated with said rails (110, 111) are respective sensors (120, 121) able to detect corresponding stops indicating the width of the printed circuit board (20) to be tested and control positioning of said rails (110, 111) in the correct position for conveying the circuit board (20); and wherein further pairs of rails (210, 211; 310, 311) are provided for conveying the printed circuit board (20) to other stations of the test machine, such as a loading station or module (2) and an unloading station or module (3), characterized in that said rails are provided with respective sensors (220, 221; 320, 321) able to detect stops (150) in the test station (1) to position themselves in perfect alignment with the rails (110, 111) of the test station (1).
