Abstract: A stopping device for an automation module for a printed circuit board (PCB) wherein the PCB is stopped in a stopping position and then removed from the stopping position. A stopping means serves to stop in the stopping position a PCB which is fed on a conveyor of the automation module that can impart an acceleration to the PCB. A pressure means is provided to apply pressure on the PCB when it arrives in the vicinity of the stopping position so as to impart a deceleration to the PCB and avoid rebound thereof against the stopping means. The pressure means also applies pressure on the PCB when it is removed from the stopping position by the conveyor to enable the conveyor to impart an acceleration to the PCB.

Abstract: A testing method and machine for automatic adjustment of the conveying means for printed circuit boards (20) in a test machine of modular type, comprising a test module (1), a loading module (2), and an unloading module (3), wherein respective moveable rails (110, 111; 210, 211; 310, 311)are provided to support the rails (110, 111) are moved toward each other, with an independent movement, and temporarily stopped on detection of corresponding stops (26) indicative of the width of the printed circuit board (20) to be tested, then withdrawn by a fixed, pre-established distance, so as to be disposed in the correct conveying position, the rails (210, 211; 310, 311) of the other modules (2, 3) being brought toward each other and stopped on detection of fixed stops in the test module (1), so as to be disposed in perfect alignment with the rails (110, 111).

Abstract: A stopping device (30) for automation modules of printed circuit boards (PCB) comprises stopping means (31) to stop a PCB (1) advancing on a conveyor (20) of an automation module in a stop position and pressure means (36) to apply pressure on the PCB (1) when it arrives in the vicinity of the stopping position, so as to avoid rebound of the PCB (1) against the stopping means (31) and impart pressure on the PCB (1) when it must be removed from the stopping position, so as to give the PCB a high acceleration.

Abstract: A method and a device for automatic adjustment of the conveying means for printed circuits (20) in a test machine of modular type, comprising a test module (1), a loading module (2), and an unloading module (3), wherein respective moveable rails (110, 111; 210, 2111; 310, 311) are provided to support said means for conveying the printed circuit (20), advantageously in the form of belts (10, 119), wherein said rails (110, 111) are moved toward each other, with an independent movement, and temporarily stopped on detection of corresponding stops (26) indicative of the width of the printed circuit (20) to be tested, then withdrawn by a fixed, pre-established distance, so as to be disposed in the correct conveying position, the rails (210, 211; 310, 311) of the other modules (2, 3) being brought toward each other and stopped on detection of fixed stops in the test module (1), so as to be disposed in perfect alignment with said rails (110, 111).
