The driving clamping module drives the guiding push block forward through the driving cylinder to realize the feeding movement, so that the outer circumferential surface of the bearing push column abuts against the guiding inclined surface and moves along the guiding inclined surface, so that the pushing and pressing seat drives the abutting block to abut on the side of the limiting seat. The lifting module realizes the unlocking of the plug-in in the locking sleeve by lifting the quick-change plug-in, which is convenient for quick replacement. The present invention realizes the automatic electrical measurement and scanning of electronic components, realizes the quick replacement of the fixture limiting component through the lifting of the quick-change plug-in by the lifting module, and realizes the limiting and clamping through the cooperation of the driving clamping module and the pushing and pressing seat.

One end of a first compression spring is connected to the side of the pushing and pressing seat, and the other end of the first compression spring is connected to a connecting block on the mounting plate. The pushing and pressing seat is slidably arranged on the mounting plate through a guide rail. Thus, when the guiding push block moves forward, the electronic component is pressed against the first stopper through the pushing surface for limitation, and when the guiding push block moves forward, the two right-angle sides of the electronic component are simultaneously pressed and limited.

Both the feeding conveying device and the discharging conveying device include a material conveying module, a material rack, a lifting module, a material rack connected to the output ends of the material rack and the lifting module, and a material receiving module provided between the material conveying modules.

The second material receiving cylinder drives the material receiving adjustment gear to rise, so as to realize the docking of the material conveying module and the material rack. The material receiving adjustment gear is respectively meshed with the first gear and the second gear, so as to realize the transportation of the loading tray between the conveyor belt on the material conveying module and the feeding conveyor belt on the material rack.

[0038] The working process of the present invention is as follows: The first material receiving cylinder 842 and the second material receiving cylinder 843 drive the material receiving connecting seat 844 to move upward for adjustment.
