Description
Technical field
The invention belongs to pick-up unit technical field, specifically, particularly a kind of mechanism for detection of standard fasteners.
Background technology
In recent years, utilizing machine vision technique to carry out having done large quantity research aspect Quality Detection 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, in modern manufacturing industry, there is important application prospect, in the fields such as machining accuracy detection, workpiece size measurement, product detection, just obtaining applying more and more widely at present, vision detection technology provides a kind of desirable means for solving on-line measurement problem.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.
Standard fasteners 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 as fundamental parts.Online or the final mass of standard fasteners detects the control of the quality and the enterprise cost that directly affect standard fasteners.Taking hex bolts as example, 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 is, by cold-drawn wire drawing, the diameter control of the wire rod of steel mill's production is arrived to given size, and ensures the smooth of wire surface; Cold-heading is to be polished rod bolt by mould the wire rod cold-heading molding after wire drawing; Thread rolling is the screw portion machining screw at polished rod bolt by automatic flat die thread-rolling machine; Thermal treatment is to eliminate cold working stress by forms such as tempering, ensures intensity and the toughness of bolt; Zinc-plated or blackout is to get rusty for 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, be operating personnel measure bolt every now and then physical dimension with survey instrument, this manual detection method has not only been wasted a large amount of time and manpower, and low precision, probability undetected, flase drop is also very high, greatly reduces the work efficiency of enterprise and has increased the labour cost of enterprise.
At present existing indivedual enterprise developments go out the pick-up unit based on vision, 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, after then being detected by testing agency, is divided into certified products and unacceptable product.Find with reality investigation by analysis, existing pick-up unit still has following deficiency:
The first, the function that testing agency can detect is less, and accommodation is narrow.As detecting to detect, screw thread has or not basic detections the such as whether tapping, length enough, 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, must buy the different pick-up unit of many covers and detect, enterprise produces to drop into be increased.
The 3rd, a kind of standard fasteners part has plurality of specifications, screws as different in nominal diameter, and its size differs larger, as screws such as M1.4, M4, M8, M10, M12, M20.The detection dish of existing pick-up unit need be to detection dish of the part respective production of each specification, the corresponding detection dish of changing will survey different size part time, the problem such as so just cause pick-up unit cost to increase, detection efficiency is not high.
The 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 the work efficiency of enterprise and labour cost problem thoroughly do not solve.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of detection efficiency high, can effectively prevent the mechanism for detection of standard fasteners that seized part comes off.
Technical scheme of the present invention is as follows: a kind of mechanism for detection of standard fasteners, there is board (5), top at described board (5) is provided with indexing rotary table, this indexing rotary table is by upper stepper motor (15) driven rotary of installing of board (5), above described indexing rotary table edge, be provided with a CCD camera (6), the camera lens of the one CCD camera (6) down, the 2nd CCD camera (7) and the 3rd CCD camera (8) are set on the side of indexing rotary table, described the 2nd CCD camera (7) is near the 3rd CCD camera (8), the camera lens of the 2nd CCD camera (7) and the 3rd CCD camera (8) is all towards indexing rotary table,
Partly be surrounded with slip-off preventing baffle plate (9) in the periphery of described indexing rotary table, this slip-off preventing baffle plate (9) is circular arc, and the head and the tail two ends of slip-off preventing baffle plate (9) and the position near middle part are fixed on board (5) by support;
Also be provided with the slideway (10) for accepting part on the side of described indexing rotary table, this slideway (10) and the separation of the 2nd CCD camera (7) are in the both sides of indexing rotary table, and slideway (10) is positioned at the downstream of slip-off preventing baffle plate (9) tail end, the high endpiece low dip of described slideway (10) entrance point arranges, and be fixedly mounted on board (5), be provided with the disengaging yoke (11) for part being allocated to described slideway (10) on the side of slideway (10) entrance point, this disengaging yoke (11) is positioned at the top of indexing rotary table, one end of disengaging yoke (11) is fixed on board (5) by bearing, the other end of disengaging yoke (11) is obliquely extended to the top at indexing rotary table edge,
