Technical field
The utility model relates to part test technique automatic fields, and in particular to a kind of overall merit rivet detection dress
It sets.
Background technique
Rivet is a kind of connector, as shown in Figure 1, being widely used among the various equipment such as aviation, ship.For example,
There are a large amount of rivets on airframe, for being connected and fixed between aircaft configuration and covering, rivet quality direct relation aircraft
It can safety.To guarantee equipment quality, security risk is excluded, it usually needs detect to rivet quality.Rivet detection content packet
Include dimensional measurement and surface defects detection.Dimension data includes rivet stem diameters and the length of rivet, manufactured head thickness, top surface outer circle
Diameter, countersunk head face cone angle etc..In each dimension data, quality is influenced maximum to be rivet stem diameters, if diameter is too small, is riveted
Built on the sand, it if diameter is too big, is difficult to be inserted into rivet hole.The accurate rivet stem diameters that obtain usually require the contacts such as vernier caliper
Measuring device.Detection rivet quality also need carry out defects detection, common deficiency include manufactured head notch, crackle, folding, pit,
Scratch etc..In various defects, manufactured head notch, crackle, and since material folds into the folding formed inside rivet these types
Defect is easy to cause stress to concentrate, and will seriously reduce rivet mechanical property, therefore should detect in time.Traditional rivet detection is general to be used
Manual type is completed, if number of rivets is huge, can also take sampling observation mode sometimes.Rivet sizes are smaller and quantity is more, tradition
The size results of artificial detection are easy missing inspection rivet surface defect there are subjective bias, and detection efficiency is low.Therefore, to mention
High rivet detects speed and quality, meets scale equipment production requirement, there is an urgent need to develop the automation rivets of efficiently and accurately
Detection device.
Current existing automation rivet detection device is all based on greatly machine vision technique, the rivet image obtained from shooting
Middle detecting size and defect.Document [1] has developed a set of pulling rivet on-line detecting system, makes rivet by electromagnetic suction head and push rod
It is accurate to reach camera site, then rivet image is shot in different angle using multiple cameras.Since electromagnetic suction head can only adsorb
The magnetic materials such as carbon steel, silicon steel, therefore aluminum rivet can not be detected.Document [2] devises a turntable to transport rivet, uses
Multiple cameras shoot different angle rivet image during rivet transports, as shown in Figure 2.It is abnormal for the target in rivet image
Change problem, document [2] also proposed a kind of aberration correction algorithm to improve rivet sizes measurement accuracy to a certain degree.Document
[3] rivet is equally transported using rotating circular disc, and acquires rivet side profile image during rivet transports, at image
Reason technology obtains rivet sizes, as shown in Figure 3.By installing probe around fastener in document [4], using ultrasonic wave to tight
The size of firmware is detected, as shown in Figure 4.

In conclusion the rivet detection device currently based on machine vision has the following problems:
1) rivet stem diameters size detection result inaccuracy.Currently based on the detection method of machine vision from rivet side view
Nail rod diameter is extracted as in, is easy to appear scale error.Firstly, the relative position of rivet and camera is not fixed, rivet is caused to exist
Size in image changes.In addition, the optical distortion in image shoot process makes rivet deform.Two parts pass through
When rivet interlacement, rivet bar is main stressed member, and rivet diameter directly affects part quality of connection, and existing method is difficult to
To accurate diameter dimension；
2) existing apparatus needs to install multiple cameras.The Image Acquisition mode of existing method is that rivet is motionless, passes through laying
Multiple cameras obtain the rivet image of different perspectives.To obtain rivet side and top image, at least need in rivet side cloth
A camera is set, arranges a camera in rivet top surface.It after camera quantity increase, also needs to be equipped with the attachmentes such as corresponding light source, increase
System control complexity and lower deployment cost are added；
3) existing device can only detect single rivet substantially, for other fastener (screw, bolt, nut etc.) nothings
Method is detected, for detection system.
