[0027] Among them, the intermittent drive mechanism 7 includes a rotating shaft 71, which is rotatably connected to the workbench 1 and the top end is fixedly connected to the turntable 5, a groove wheel 72 is fixedly connected to the rotating shaft 71 and located below the workbench 1, an active turntable 73 is arranged on the outer side of the groove wheel 72, a pin 74 is arranged on the active turntable 73, a driving motor 75 is fixedly installed at the bottom of the active turntable 73, a bracket 76 is fixedly installed at the bottom of the driving motor 75, and the bracket 76 is fixedly installed at the bottom of the workbench 1.

[0028] Therefore, in the above structure, when conducting quality inspection on electronic components, it is only necessary to place the components to be inspected in the vibrating screening loading tray 2, and the vibrating screening loading tray 2 will transport the electronic components one by one to the corresponding material trough 6, and then the intermittent driving mechanism 7 will drive the indexing disk 5 to rotate, and the electronic components will be indexed to the inspection mechanism 4 for inspection through the indexing disk 5. After the inspection is completed, the electronic components will be sent to the conveyor belt 8 through the intermittent driving mechanism 7, and the unqualified components will be pushed and sorted to the unloading platform 10 through the pushing component 9. The whole process avoids the need for continuous intermittent start and stop of traditional conveying equipment, reduces the number of pauses of the conveyor belt equipment, and improves the working efficiency, reliability and service life of the whole device.

[0029] The intermittent drive mechanism 7 drives the active turntable 73 and the detent pin 74 to rotate through the drive motor 75, drives the groove wheel 72 to rotate intermittently through the detent pin 74, and then drives the rotating shaft 71 and the indexing disk 5 to rotate intermittently. During this period, the drive motor 75 does not need to be started and stopped intermittently, and the phenomenon of continuous intermittent start and stop loss will not occur.

[0030] Furthermore, a limit ring 14 is provided on the workbench 1 and outside the rotary disk 5, and a notch is provided on the limit ring 14 at the conveyor belt 8. The design of the limit ring 14 plays a role of limit guide.

By providing the buffer spring 95 and the buffer block 94, when the push block 93 contacts the electronic product, the buffer spring 95 can play a buffering effect, thereby preventing the electronic product from being damaged by excessive force at the moment of contact with the push block 93.
