Waveform inspection adjusting device and method with multi-model inspection

摘要

The present invention relates to a waveform inspection adjusting device and method having a multi-model inspection function which includes a plurality of pictures having pins for two or more models and which can inspect a printed circuit board of multiple models by pin switching and fixture switching. The present invention relates to a jig having a plurality of fixtures having two or more inspection model pins, and to controlling each device to detect a waveform from the printed circuit board transferred to the jig, thereby determining whether to adjust the detected waveform. A PC section, a measurement section for applying a power supply and a predetermined reference signal to the jig according to the operation control signal from the PC section, and detecting an operation waveform according to the jig, and a volume adjustment terminal under control from the PC section. The motor unit for operating and moving the fixture to the inspection position, and for detecting the position of the fixture moved by the motor unit to output to the PC unit A sensing unit, a pin manipulation unit for contacting the measuring unit with a pin corresponding to the inspection model of the printed circuit board transferred to the jig, and a plurality of fixtures provided in the jig under the control of the PC unit are provided on the printed circuit board. A fixture driving unit which raises and lowers to be contacted, a programmable logic controller which controls the conveyor driving unit which stops / drives the conveyor under the control of the PC unit, and a conveyor driving unit which stops and drives the conveyor by the control of the programmable logic controller. do.
