Description
Technical field
The utility model belongs to pick-up unit technical field, specifically, and particularly a kind of standard fasteners machine vision detection device.
Background technology
In recent years, utilizing machine vision technique to carry out in Quality Detection, having done large quantity research abroad, and obtaining many important achievement.Vision-based detection has the advantages such as noncontact, speed is fast, precision is high, antijamming capability is strong, important application prospect is had in modern manufacturing industry, just obtaining applying more and more widely at present in the fields such as machining accuracy detection, workpiece size measurement, Product checking, vision detection technology is solve on-line measurement problem to provide a kind of desirable means.The eighties in 20th century, NBS once did prediction on the basis of investigation: 80% of industrial detection work from now on will be completed by vision detection technology.
Based on standard fasteners, part all has a wide range of applications in many industries of the national economy such as auto industry, machinery manufacturing industry, building industry, electronics industry.Online or the final mass of standard fasteners detects and directly affects the quality of standard fasteners and the control of enterprise cost.For hex bolts, hex bolts is as the most common connection securing member of one, and its manufacturing process is: wire drawing, cold-heading, thread rolling, thermal treatment, zinc-plated or blackout etc.Wire drawing be the diameter control of wire rod steel mill produced by cold-drawn wire drawing to given size, and ensure the smooth of wire surface; Cold-heading is polished rod bolt by mould the wire rod cold-heading molding after wire drawing; Thread rolling is by the screw portion machining screw of automatic flat die thread-rolling machine at polished rod bolt; Thermal treatment eliminates cold working stress by forms such as tempering, ensures intensity and the toughness of bolt; Zinc-plated or blackout is got rusty in order to anti-, strengthens the resistance to corrosion of bolt.Each production link has corresponding detection method, to ensure the correctness of this link.From the angle of quality control, particularly important to the detection of bolt.
For a long time, the detection of hex bolts mainly relies on artificial mode, namely operating personnel measure the physical dimension of bolt every now and then with survey instrument, this manual detection method not only wastes a large amount of time and manpower, and low precision, probability that is undetected, flase drop is also very high, greatly reduces the work efficiency of enterprise and adds the labour cost of enterprise.
Existing indivedual enterprise development goes out vision-based inspection device at present, and wherein, part indexing rotary table is the important component part in this pick-up unit, and part to be checked reaches part indexing rotary table, is divided into certified products and unacceptable product after then being detected by testing agency.Investigate with reality by analysis and find, existing pick-up unit still has following deficiency:
The first, the function that testing agency can detect is less, and accommodation is narrow.Substantially, to detect with or without whether tapping, length enough etc. as thread measurement can only detect, can not double thread pitch, the whether qualified detection of thread form, and accuracy in detection is not high, still has higher faulty materials after detection.
The second, a kind of pick-up unit can only detect a kind of part, and standard fasteners enterprise generally produces various parts, as screw, nut, bolt etc., if all apply automatic detection device, the pick-up unit must buying many covers different detects, and enterprise's Productive statistics increases.
3rd, a kind of standard fasteners part has plurality of specifications, screws as different in nominal diameter, and its size difference is comparatively large, as screws such as M1.4, M4, M8, M10, M12, M20.The detection dish of existing pick-up unit need to part respective production detection dish of each specification, correspondingly when will survey different size part changes detection dish, so just causes the problems such as pick-up unit cost increases, detection efficiency is not high.
4th, existing pick-up unit just detects faulty materials, and detecting qualified part also needs 1-2 name workman to carry out bag distribution packaging, and work efficiency and the labour cost problem of enterprise thoroughly do not solve.
Utility model content
It is high that technical problem to be solved in the utility model is to provide a kind of detection efficiency, and the standard fasteners machine vision detection device that can effectively prevent seized part from coming off.
The technical solution of the utility model is as follows: a kind of standard fasteners machine vision detection device, there is board (5), in the one end at described board (5) top, vibrating disk (13) is installed, the other end at board (5) top arranges indexing rotary table, this indexing rotary table is by upper stepper motor (6) driven rotary of installing of board (5), the guide rail (10) of conveying parts is provided with between described vibrating disk (13) and indexing rotary table, this guide rail (10) entrance point height endpiece low dip is arranged, the entrance point of guide rail (10) connects with the part mouth that goes out on vibrating disk (13), the endpiece of guide rail (10) is near described indexing rotary table,
Described guide rail (10) is made up of the fixing conveyor track (10a) be arranged side by side and adjustable conveyor track (10b), described fixing conveyor track (10a) is supported on board (5) by the first bracing frame (11), adjustable conveyor track (10b) is supported on board (5) by the second bracing frame (12), the bottom of the second bracing frame (12) is fixed by bolt and board (5), and the hole that the second bracing frame (12) bottom is passed through for bolt is bar hole;
