Industrial personal computer control, for realizing the sorting of non-defective unit and substandard products.
Preferably, the guide rail forms a guide part close to the side of the conveyer belt, and the lower ora terminalis of the guide part is high
In the upper surface of the conveyer belt.
After adopting the above technical scheme, the utility model compared with the background art, has the advantages that
The utility model enough ensures the accuracy of testing result, saves manpower, provides detection efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model signal control schematic diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment
Fig. 1 and Fig. 2 are please referred to, the utility model discloses a kind of, and the workpiece surface quality based on machine vision detects dress
It sets, including feeding unit 1, proximity sensor 2, area array cameras 3, LED flash 4, time delay module 5, industrial personal computer 6 and material picking mechanism
7, in which:
Refering to what is shown in Fig. 1, feeding unit 1 includes vibrating tray 11, guide rail 12 and conveyer belt 13, guide rail 12 is set to vibration material
Between disk 11 and conveyer belt 13.Guide rail 12 is domed, the speed in this way during workpiece A carries out upper cunning, downslide by guide rail 12
Variation can be generated, so that it may so that the workpiece A being located next to realizes separation, that is, realize the separation of adjacent workpieces A.Guide rail 12 is close to conveying
Side with 13 forms a guide part 131, and the lower ora terminalis of guide part 131 is higher than the upper surface of conveyer belt 13, in this way when workpiece A reaches
After on to conveyer belt 13, make workpiece A proper alignment on conveyer belt 13 by guide part 131, it is ensured that area array cameras 3 is captured to be shone
Piece is consistent.
Cooperate Fig. 1 and Fig. 2 shown in, proximity sensor 2, area array cameras 3, LED flash 4 along workpiece A conveying direction successively
The top of conveyer belt 13 is set.The signal input part of time delay module 5 connects proximity sensor 2, and signal output end connects respectively
Junction array camera 3 and LED flash 4.Trigger signal is generated when proximity sensor 2 detects workpiece A, time delay module 5 is based on
Trigger signal outputs signal to area array cameras 3 and LED flash 4, and it is synchronous to guarantee that area array cameras 3 works with LED flash 4
Property, and ensure that workpiece A when area array cameras 3 and LED flash 4 work just is transported to the field of view center of area array cameras 3.This reality
The time delay module 5 applied in example is made of signal conditioning circuit and delay circuit, and signal conditioning circuit is used for above-mentioned trigger signal
It is filtered, rectifies, be then sent to delay circuit and be delayed.
Industrial personal computer 6 is separately connected area array cameras 3 and material picking mechanism 7.Industrial personal computer 6 receives the workpiece figure that area array cameras 3 is shot
Picture, and be analyzed and processed, to carry out detection judgement to workpiece surface quality.Industrial personal computer 6 is according to detection judging result output control
Signal processed, material picking mechanism 7 carry out sorting operation according to the control signal.
Material picking mechanism 7 includes material carrier platform 71 and two manipulators 72, and material carrier platform 71 is set to the end of conveyer belt 13, two machines
Tool hand 72 is arranged in the top of material carrier platform 71 and is controlled by industrial personal computer 6, for realizing the sorting of non-defective unit and substandard products.Material carrier platform 71 leans on
The side of nearly conveyer belt 13 forms an inclined surface 711, and workpiece A so after testing is delivered to by conveyer belt 13 close to material carrier platform
When 71, it can be slided on material carrier platform 71 by inclined surface 711.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
