And second vacuum chuck 83 generate negative pressure so that the second vacuum chuck 83 piston rod elongation and close to polycrystalline diamond it is compound
Piece, then composite polycrystal-diamond is adsorbed by the second vacuum chuck 83, and then telescopic cylinder 82 acts again, so that piston rod
It shrinks, the sliding shoe of subsequent synchronous belt slide unit 81 continues to slide towards first end, drives composite polycrystal-diamond towards turntable 41
Sliding, until sliding shoe when composite polycrystal-diamond is corresponding with turntable 41 on synchronous belt slide unit 81 stops sliding, with
Telescopic cylinder movement extends piston rod afterwards, so that the lower end surface of composite polycrystal-diamond be driven to connect with turntable 41
Touching, subsequent second vacuum chuck 83 disconnects gas, so that the second vacuum chuck 83 can not generate negative pressure, so that polycrystalline diamond be answered
It closes piece to separate from the second vacuum chuck 83, and then composite polycrystal-diamond is placed on turntable 41.In addition, blanking device
The course of work and feeding device the course of work it is distinct, for expansion, in blanking device, first pass through in blanking device same
The composite polycrystal-diamond on the second vacuum chuck absorption mounting table on the sliding shoe with slide unit is walked, in subsequent blanking device
The second end of the sliding shoe of synchronous belt slide unit towards synchronous belt slide unit is slided, and composite polycrystal-diamond is then placed in blanking dress
On the transfer plate set, subsequent transfer plate leaves monitor station by the cooperation of the second screw rod and the second thread bush.
In the present invention, transfer plate above-mentioned is counter sink acrylic transfer plate.
The course of work of the invention are as follows: composite polycrystal-diamond is placed in first on the transfer plate 72 of feeding device, is led to
The polycrystalline diamond on the transfer plate 72 in feeding device is answered in the cooperation for crossing mobile device and carriage in feeding device
It closes piece to be adsorbed on rotation detection zone (i.e. turntable 41), with the movement of trailing flank detection device to the plycrystalline diamond on turntable 41
The side of the PDC layer of diamond compact is shot, and is then adsorbed gearshift and is answered the polycrystalline diamond on turntable 41
It closes piece to be transferred on mounting table 45, mounting table 45 is moved to the second end of the first screw rod in the transmission of transmission device during this
Place, subsequent transmission device movement drive mounting table 45 to be moved in the detection zone of upper surface, and subsequent upper surface detection device is to placement
The upper surface of composite polycrystal-diamond on platform 45 is shot, and subsequent transmission device drives mounting table 45 to continue to move to, this
When composite polycrystal-diamond there are two types of situation, the first situation are as follows: if to be detected as surface defective for composite polycrystal-diamond,
Mounting table 45 be moved into it is corresponding with the piston rod of pusher cylinder, then will be on mounting table 45 by the flexible of piston rod
PDC, which is pushed away, to be dropped down onto collection box；Second situation: if composite polycrystal-diamond surface zero defect, mounting table 45 are moved into
The second end of second screw rod, subsequent blanking device movement, the composite polycrystal-diamond on mounting table 45 is transferred to down
On the transfer plate for expecting device.
It should be noted that automatic detection device further includes PLC control system, air pump, each driving device driving end and
The output end of side line-scan digital camera 31 and end face camera 34 is connected in PLC control system, and by PLC control system
The picture that image processing unit transmits lateral side wire array camera 31 and end face camera 34 carries out image procossing and judgement, is determined with this
Whether the side and upper surface of PDC be defective.In the present invention, this PLC control system is existing conventional control system, such as three
The control system of the model FX3U-32MT/ES-A of water chestnut company production.
The foregoing is merely the preferred embodiment of the present embodiment, all equivalent changes done with scope of the invention as claimed
And modification, it should belong to scope of the presently claimed invention.
