Connection, the server 6 carry out data analysis and image procossing to described image sensor acquired image, and will be at analysis
Reason result is sent to the display 7 and is shown.Concrete operations are as follows:
Identification of Cracks is carried out to the acquired image, and calculates the length of crackle according to imaging parameters, judges crackle
Whether length is more than preset length value, if so, marking the crackle on this image, and marks its length.
Except this, the server 6 is also used to store the image set of captured in real-time, the system also includes input equipment, when
The input equipment inputs triggering command to server, then the control of server 6 plays described image collection on the display 7.
Over the display due to the image information display that acquires ccd sensor, in order to which personnel observe (without very important person
At the moment carve aligming microscope lens barrel peephole).
The application method of the quality detecting system of the utility model is as follows:
The drag link bushing for completing fatigue detecting is placed in the locating slot 31, and will be on the drag link bushing
First reference mark (not shown) is aligned with special angle (such as 0 °) graduation mark on turntable 3, then by 0 ° of quarter on turntable 3
Degree is aligned with the second reference mark 11 on pedestal 1, then adjusts displacement mechanism, so that detector lens 4 are directed at drag link bushing
On plastics/rubber parts, then rotate the turntable 3, until 0 ° of scale and the second reference mark 11 on pedestal 1 it is right again
Together, the detection process to a drag link bushing is completed, in the process, if it find that the plastic part of above-mentioned drag link bushing/
There is the crackle more than certain length on rubber parts, then determines that it is rejected product, it is preferable that while it is right to record discovery crackle institute
The angle answered, in this way, being taken out from the locating slot 31 on the turntable 3 even if will test part, it is only necessary to again by the first benchmark
Mark is directed at the special angle, and place angle, can again arrive the Crack Rotational when then rotating turntable 3 to discovery crackle
Within the scope of camera lens；By detecting a considerable amount of drag link bushings, statistics obtains the qualification rate of product.
The driving mechanism and imaging sensor of the display 7 and detector are connect with server 6, the server 6
Data analysis and image procossing are carried out to described image sensor acquired image, and analysis and processing result is sent to described
Display 7 is shown.
Wherein, it finds to can be used on plastic part/rubber parts of above-mentioned drag link bushing in the presence of the crackle more than certain length
Following manner:
Acquired image information is sent to server 6 by the imaging sensor (such as ccd sensor) of the detector,
The server 6 shows picture on the display 7, it is preferable that the server 6 carries out data to the acquired image
Analysis and image procossing: Identification of Cracks is carried out to the acquired image, and calculates the length of crackle according to imaging parameters, is sentenced
Whether failure crack length is more than preset length value, if so, marking the crackle on this image, and marks its length, even
The alert when finding long crack prompts testing staff's processing.
It is described the system also includes manipulator (not shown) in order to realize the artificial full-automatic detection system of liberation
Manipulator is connect with server 6, under the control of server 6, manipulator crawl sample be put into locating slot 31 or from
The sample is taken out in the locating slot 31.
The application method of full-automatic quality detecting system is as follows:
Server is sent out according to the distance between the distance between manipulator and sample, sample and locating slot 31 to manipulator
Move is sent, the move includes the length in mobile direction and movement and the angle of rotation, and grabs sample
It is moved to the displacement strategy of locating slot 31 afterwards, manipulator grabs sample and place it in locating slot according to above-mentioned move
In 31, the angle of manipulator rotation will guarantee on the first reference mark (not shown) and turntable 3 on sample (drag link bushing)
Special angle (such as 0 °) graduation mark alignment, then adjust displacement mechanism so that detector lens 4 be aligned drag link bushing on
Plastics/rubber parts, then server is instructed to driving motor one, and turntable 3 described in motor task driven rotates 360 °, completion pair
The detection process of one drag link bushing, in the process, if it find that being deposited on plastic part/rubber parts of above-mentioned drag link bushing
It is being more than the crackle of certain length, then is determining that it is rejected product, it is preferable that while angle corresponding to discovery crackle is recorded,
In this way, being taken out from the locating slot 31 on the turntable 3 even if will test part, it is only necessary to the first reference mark are directed at institute again
Special angle is stated, place angle when then rotating turntable 3 to discovery crackle can be again by the Crack Rotational to camera lens range
It is interior；When a sample completes detection, by server to one, manipulator instruction, its load is driven to complete the sample of detection extremely
Specified region, for example qualified product storage area is loaded onto for the sample of testing result qualification and is unloaded, and for testing result
Underproof sample is loaded onto rejected product storage area and is unloaded, and when unloading can put in sequence, is equivalent to automatic
Number is generated for it.Then the sample that manipulator grabs non-detection zone again is put into locating slot 31 and is detected, and repeats above-mentioned
Step, details are not described herein.
Quite high requirement is proposed to the precision of manipulator above, in this regard, the utility model embodiment also provides one kind
Semi-automatic detection method greatly reduces the operating characteristics requirement to manipulator, and process is as follows:
Manipulator can be moved to following fixed point: fixed point one, non-test sample region, by manually by part according to default
Required angle put for manipulator be loaded onto locating slot (such as: make the first reference mark on sample and the quarter of 0 ° on turntable
Spend line alignment)；Fixed point two is moved to above locating slot, and declines certain altitude, unloads, and so that sample is fallen into locating slot (and mechanical
The first reference mark on each sample of hand crawl is aligned with identical graduation line on turntable)；Fixed point three, collecting zone, to
After motor driven turntable rotates 360 °, manipulator decline again grabs sample, and is loaded onto collecting zone and (can be divided into qualified product area
Domain and rejected product region).
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
