Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1 to 4 is please referred to, the utility model provides a kind of technical solution: a kind of cage guide mortise and tenon detection device, packet
Include processor, image pick-up card, CCD camera, sensor and LED light source, the output end of the CCD camera and image pick-up card
Input terminal connection, the output end of described image capture card and the input terminal of processor connect, the output end of the sensor and place
The input terminal connection of device is managed, the output end of the processor and the manipulation end of CCD camera connect, and the LED light source is used for CCD
The operation of camera light filling.
There are two the detection device settings, and two detection devices are arranged oppositely respectively in the two sides of guide rail conveyer belt.
As shown in figure 5, the detection device further includes PLC controller and alarm, the output end of the processor with
The input terminal of PLC controller connects, and the output end of the PLC controller and the control terminal of alarm connect, and is passed according to computer
Unqualified signal out, driving alarm issue information warning, the guide rail size precision of detection are prompted not reach requirement.Otherwise, nothing
Warning message directly detects next guide rail.
The processor is computer.
The CCD camera is the undistorted camera of high definition, reduces the distortion of image in collection process, is reduced to dimensional accuracy
It influences.
The sensor is position sensor.
The LED light source is annular light source, and annular light source is placed in below CCD camera, when guide rail runs to camera position,
Annular light source is its polishing, and camera takes pictures to polishing product.
By the technical program, detection device mainly include CCD industrial camera, image pick-up card (image pick-up card, mainly
It is to acquire the width of guide rail front mortise and tenon by CCD camera and highly with vertical view face picture traverse and depth, pass through computer
Image is pre-processed, provides clear image for size detection below), LED light source, sensor, data acquisition card and calculating
Machine；Sensor is monitored the guide rail on conveyer belt and computer numbers it, when detecting that guide rail arrives by telecommunications
Number computer is sent to by data acquisition card, data acquisition card carries the transmission and reception of electric signal；CCD camera and LED
Light source according to computer transmission come electric signal the guide rail of number is carried out polishing and taken pictures to acquire image, by collected number
Image is transferred to computer by image pick-up card, and image pick-up card is acquired and transmits to digital picture；Calibrating template is
Based on LabVIEW platform, using the dot matrix mark with obvious characteristic and corresponding relationship in the calibration process under LabVIEW platform
Fixed board, the distance in scaling board between the radius and the adjacent dot center of circle of each black dot be it is constant, pass through utilization
Canny filter can extract the edge of each black dot in calibrating template, and edge is recycled to carry out round fitting, obtain every
A accurate center location of black dot, ensure that the precision of coordinate.
When guide rail to be checked is run in conveyer belt, sensor detects that guide rail arrives, the device at both ends by LED light source polishing,
CCD camera takes pictures to it, and collected digital picture is transferred to computer by image pick-up card, has computer to determine image
Position, then extracts interested feature, carries out Hough transform straight-line detection to the size of characteristic, compares calibrating template, defeated
Testing result out, when result is improper, PLC controller drives alarm to issue alarm signal.
When the guide rail conveyer belt move when, monitored by the position sensor, obtained signal be transferred to institute
Computer is stated, electric signal is sent to annular light source by computer, and annular light source gives negative tenon and the sun tenon polishing of guide rail respectively at this time,
It is taken pictures (as shown in Figure 3) by CCD camera to the front of negative tenon and positive tenon and vertical view face, then passes through collected digital picture
Image pick-up card is transferred to computer.
The width m of guide rail yin tenon as shown in Figure 1:1；Guide rail sun tenon width m2；The depth t of guide rail yin tenon1；Guide rail sun tenon
Depth t2；The height h of guide rail yin tenon and positive tenon；
The above parameter is the size that the utility model predominantly detects.
Main difference is that positive tenon is protrusion, the standard size of protrusion is t at cage guide mortise and tenon both ends2, negative tenon is
Recess, depth dimensions t1。
Computer acquisition guide rail mortise and tenon image, and image is pre-processed by detection device, then pass through
LabVIEW platform determines the coordinate of detection zone to image calibration.
Computer starts to carry out acquired image analysis and calculates size, direct picture detection mainly to negative tenon and
