A kind of diaphragm quality visible detection method of the invention is described in detail below.
Above-mentioned diaphragm supplied materials quality vision-based detection system can be used in a kind of diaphragm quality visible detection method of the invention
System.Detection method can include:
Advance firstly, drawing diaphragm by servo manipulator.Wherein, for the diaphragm of different size length, in setting
In length, step traction is carried out to the diaphragm supplied materials in unreeling by servo manipulator.
When diaphragm, which advances to two lines, to be swept below camera, PLC control opens two lines and sweeps camera, grows to setting in advance
Each membrane-bound fragment in degree carries out the segmentation detection of disparity items, and when servo manipulator stops traction by setting, two lines sweep phase
Machine after sensing, will be sent to PLC for the testing result of each membrane-bound fragment.
Wherein, when First look detection module and the second vision-based detection module certain membrane-bound fragment is not all detected it is bad
When, membrane-bound fragment qualification is judged, and manipulator is instructed to continue to continue to draw to diaphragm supplied materials, until the institute in setting length
Have membrane-bound fragment it is all qualified when.
Then, instruction cutting mechanism cuts off the qualified diaphragm for meeting setting length from diaphragm supplied materials.
Otherwise, if as long as First look detection module and the second vision-based detection module wherein have one to examine certain membrane-bound fragment
It when measuring bad, is judged as that the membrane-bound fragment is unqualified, and instructs cutting mechanism by the unqualified membrane-bound fragment and its connected leading portion
Qualified membrane-bound fragment (if there is) is cut off from diaphragm supplied materials.
Then, PLC instructs servo manipulator to be put into unqualified membrane-bound fragment and its connected leading portion qualification membrane-bound fragment accordingly
Bad recycling box in recycled.
Meanwhile PLC can will test for example bad classification of the bad data in result, bad overall size and bad diaphragm
The length of section and the area or length of negative characteristics are sent to host computer, and host computer database can be carried out and be kept records of, convenient
Later period retrospect.
For example, diaphragm supplied materials is all an entire volume, an entire volume diameter about 600mm.Need us the film of this entire volume now
According to the different model of industrial membrane, it is divided into and (being cut into) the different diaphragm one by one of different size length.In the process divided
In, it can use line and sweep camera to detect.If it find that having bad, it is necessary to which carton (bad recycling box), later period are put in excision into
Part is bad to be recycled.
In order to avoid diaphragm waste, diaphragm we generally can be divided into several sections to carry out manipulator traction.The mistake of traction
Cheng Zhong triggers two cameras while detecting.A specific diaphragm needs in a few paragraphs, can be according to the model membrane component of institute's operation
Length determines that diaphragm is longer, the number of segment being divided into is more, and the number of servo manipulator traction detection is more.
For example, the length of certain model membrane component diaphragm is 1800mm, we be divided into it 3 sections so long, and every section is about
600mm.Servo manipulator can so be set and draw 600mm every time.
If when two phase this section of diaphragms of machine testing, wherein there have a camera or two cameras to have been found that be bad, then
It is defective products that this section of diaphragm, which is just determined,.It can at this time be drawn by cutting mechanism direct shearing, after shearing by manipulator bad
Diaphragm returns, and puts into bad recycling box.Then, manipulator draws the supplied materials of next section of 600mm again from sheared edge again.
, whereas if two camera testing results are all bad without finding, then this 600mm diaphragm is exactly qualified.This
When manipulator it is previous drawn 600mm supplied materials on the basis of, be further continued for traction 600mm, while triggering phase machine testing.If this
Secondary testing result is underproof, then this total 1200mm drawn twice just needs direct shearing, and is placed it into bad
In recycling box, and from the beginning (since the initial position of a diaphragm) continue to draw.
Certainly, if the 600mm phase machine testing of second traction be it is qualified, manipulator is just in former 1200mm base
On plinth, continue to draw third section 600mm, and at the same time triggering phase machine testing.If camera testing result is qualified, this is 3 times
The correct length that total 1800mm is exactly a diaphragm is drawn, and all qualified.At this point, cutter is equally cut off, then this
1800mm qualification diaphragm flows away toward subsequent processing.
Then, manipulator returns to cutter, re-starts the traction detection of next bout.
In above-mentioned traction three times, if that 600mm of last (third time) traction be detected as it is bad, no matter before
1200mm is non-defective unit, require excision put into bad recycling box (diaphragm portion of bad recycling box can be used for other compared with
The diaphragm of short length will not waste), the whole diaphragm of only complete 1800mm is only qualified product, can be toward subsequent processing stream
It walks.
The different bad classification of phase machine testing is swept using two lines in the present invention, ensure that the accuracy of phase machine testing.Often
It opens diaphragm and needs manipulator traction several times, that is, phase machine testing is several times.Can have in this way with accurate judgement which section diaphragm it is bad, just
Can being put into bad recycling box after this section of bad cutting, avoid one whole diaphragm because have some it is slight bad and by whole
It cuts away.One diaphragm detects several times (section), effectively prevents the diaphragm for waste sheet because small bad.
In conclusion the present invention sweeps camera by installing two lines additional, the bad problem of diaphragm can be accurately and effectively detected, greatly
It is big reduce even prevent because bad diaphragm flows down and caused by quality problem, thus improve product quality；Meanwhile part
Bad diaphragm can be with recycling and reusing, to substantially increase the utilization rate of diaphragm.
Above is merely a preferred embodiment of the present invention, the scope of patent protection that embodiment is not intended to limit the invention,
Therefore all to change with equivalent structure made by description of the invention, it similarly should be included in protection model of the invention
In enclosing.
