Specific embodiment
With reference to the accompanying drawings and examples, the present invention is expanded on further.In the following detailed description, only by explanation Mode describes some one exemplary embodiments of the present invention.Undoubtedly, one of ordinary skill in the art will recognize, In the case of without departing from the spirit and scope of the present invention, can be being repaiied to described embodiment with a variety of modes Just.Therefore, accompanying drawing and description are inherently illustrative, rather than are used for limiting scope of the claims.
As shown in figure 1, bearing parts automatic sorting method according to embodiments of the present invention, the bearing parts are automatic Method for sorting is comprised the following steps:
(1) bearing parts to be detected are delivered to by detection zone by conveyer device;
(2) after the bearing parts to be detected are delivered to detection zone, trigger position detection sensor 3 by the axle to be detected Hold parts position signalling and be sent to vision detection system 4 in real time;
(3) vision detection system 4 obtains the bearing to be detected according to the positional information of the bearing parts to be detected The image of parts, and the image of acquisition is compared with bearing part-subassemble standard data;
(4) if being to close after the image of the bearing parts described to be detected for obtaining is compared with bearing part-subassemble standard data Lattice product, then certified products certified products funnel 6 is delivered to by conveyer device;
(5) if being not after the image of the bearing parts described to be detected for obtaining is compared with bearing part-subassemble standard data Certified products, then vision detection system 4 is by defective work information transmission to defective work rejecting mechanism 5, when defective work is by conveying Before device is delivered to the defective work rejecting mechanism 5, the position-detection sensor 3 detects the position letter of defective work Number, now the defective work rejecting mechanism 5 works and rejects defective work to defective work funnel 7.
In the present invention, the bearing component surface defect to be detected to processing by the way of vision is detected, Imaging clearly, can effectively ensure that the accuracy of detection;Meanwhile, using can continuous detecting conveyer device, zero, bearing to be detected While part is conveyed on a conveyor, you can complete vision-based detection, defective work reject, certified products enter basket etc. operation, improve Detection efficiency;The position-detection sensor 3 of the present invention is used for detecting position of bearings, and position signalling is sent to vision-based detection system System 4 or defective work rejecting mechanism 5, so that vision detection system 4 obtains image and bearing part-subassemble standard in the suitable time Comparing, and defective work is eliminated conveyer device in time.
Further, further comprising the steps of before described step (1):
The bearing parts to be detected are immersed in fluorescent liquid or coat fluorescent material.
So, the bearing parts described to be detected after soaking fluorescent liquid or coating fluorescent material are in the vision-based detection system When system 4 is imaged, becomes apparent from can the image of acquisition, can be more prone to tell rejected region, and make detection more accurate.
Further, the conveyer device is vibrosieve 1 and conveyer 2, and wherein described vibrosieve 1 is vibration sorter The bearing parts to be detected can be arranged in a row and be delivered on the conveyer 2 by structure, and the conveyer 2 will be described to be checked Survey bearing parts and be delivered to detection zone.
In embodiments of the invention, the vibrosieve 1 is vibration mechanism for sorting, can be by rambling bearing to be detected zero Part is arranged in a row, and which is delivered on conveyer 2 one by one, meanwhile, vibrosieve 1 conveys the speed of bearing parts to be detected can Adjust, to meet the different detection speed demands of different size bearing.
Further, the conveyer 2 conveys the bearing parts to be detected using Timing Belt.
So, while the bearing parts to be detected are fed forward on Timing Belt, you can complete vision-based detection, no Certified products are rejected, certified products enter the operation such as basket, it is preferable that Timing Belt can adopt belt, make that course of conveying is steady, noiseless, and Simple structure, cost are relatively low.
Further, the vision detection system 4 is placed in independent environment and is furnished with irradiation light, in the cooperation of irradiation light Under, the vision detection system 4 can obtain clearly image.
In embodiments of the invention, by the vision detection system 4 being placed in independent environment and being furnished with irradiation light, Can reach better image Detection results, it is ensured that disturb without other in detection process, obtain image more accurate.In particular, Irradiation light cooperates with soaking fluorescent liquid or coating the bearing parts described to be detected after fluorescent material, can reach more preferably Detection results, make image clearly, detection accurate.
Preferably, the exit of the certified products funnel 6 and the defective work funnel 7 is equipped with charging basket, is respectively used to Storage certified products and defective work.
In an embodiment of the present invention, by arranging charging basket, certified products and defective work is made to store respectively, it is to avoid part is stored up Deposit confusion or the two is obscured.
Further, further comprising the steps of before described step (1):
By conveyer device, position-detection sensor 3, vision detection system 4 and defective work rejecting mechanism 5 respectively with electric-control system 8 connections and the logical relation operation set according to the electric-control system 8.
In order to ensure the accuracy for detecting, conveyer device, the inspection of position-detection sensor 3, vision are controlled by electric-control system 8 Examining system 4 and defective work rejecting mechanism 5, can make the logically relation operation of whole control process, it is to avoid run-time error causes Bearing parts detection error.
Therefore, the present invention is detected to bearing component surface defect by the way of vision, imaging clearly, it is ensured that Detection accuracy, at the same using can continuous detecting Belt Conveying structure, improve detection efficiency.
Schematically specific embodiment of the invention is the foregoing is only, the scope of the present invention is not limited to.Any Those skilled in the art, the equivalent variations that is made on the premise of the design without departing from the present invention and principle and modification, The scope of protection of the invention should be belonged to.
