By serial communication between detection module and PLC, PLC controls LCD glass handling platform 5.
Further, described forword-looking imaging system 1 specifically includes 2 cameras, 2 camera lenses, and described backsight imaging system 2 has
Body includes 2 cameras, 2 camera lenses, and described camera lens is connected with camera, camera and camera lens place plane and LCD glass handling platform 5
Parallel, and forword-looking imaging system 1 and backsight imaging system 2 are about LCD glass handling platform 5 axial symmetry, forword-looking imaging system 1
2 cameras between arranged in parallel, arranged in parallel between 2 cameras of backsight imaging system 2.
Further, described light source 3 specifically has 4, wherein has 2 to be arranged on forword-looking imaging system 1 and LCD glass handling
Between platform 5, other 2 are arranged between backsight imaging system 2 and LCD glass handling platform 5, and are arranged on forword-looking imaging
2 light sources 3 between system 1 and LCD glass handling platform 5 or be arranged on backsight imaging system 2 and LCD glass handling platform 5
Between 2 light sources 3, wherein 1 top being arranged on camera lens, another 1 lower section being arranged on camera lens.
Further, LCD glass 4 is placed on LCD glass handling platform 5 detection.
After system start-up, first LCD glass 4 to be detected is carried out machinery location, after LCD glass 4 carries out machinery location,
PLC controls LCD glass handling platform 5, makes LCD glass handling platform 5 perform to be carried to LCD glass 4 operation of detecting position.
After PLC detects that LCD glass 4 is carried to detecting position, will pass through serial ports and will send the Intelligent Measurement mould to PC end to bit instruction
Block, after the Intelligent Measurement module of PC end receives bit instruction, then controls forword-looking imaging system 1, backsight imaging system 2 and light
Source 3 carries out imaging and detection operation to the edging edge of the LCD glass 4 of current detection position.When current detection position has been detected,
First determine whether whether the edging of LCD glass 4 has detected, if detected, then LCD glass 4 is carried to next station, terminates
Edging effect detection to LCD glass 4；If do not detected, then shift instruction is sent out by Intelligent Measurement module by serial communication
Deliver to PLC, after PLC receives the shift instruction that Intelligent Measurement module sends over, just control LCD glass handling platform 5, make
LCD glass handling platform 5 performs to be carried to by LCD glass 4 operation of next detecting position, LCD glass according to default translocation distance
After LCD glass 4 is carried to next detecting position by glass carrying platform 5, continue the edging of the LCD glass 4 to current detection position
Edge carries out imaging and detection operation, through repeated detection, can complete the effect detection of all edging parts to LCD glass.
The described edging edge to the LCD glass 4 of current detection position carries out imaging and detection operation includes:
A. the edging edge of the LCD glass 4 of detecting position is shot, obtain the edging edge of LCD glass 4
Image.
B. described edging edge image is divided into several isometric little images, one will be entered by described edging edge image
Step is subdivided into the little image of about 0.3mm length.
The most respectively the width of described little image is measured, obtain the width measurement of little image.
The present embodiment passes through edging part and the gray scale difference of background, distinguishes the edging particular location of each little image, from
And accurately measure the pixel count obtained corresponding to corresponding little image, then (demarcate one by the pixel calibration result that system is prefabricated
The actual size that pixel represents), clear out the actual physics width of each image of edging.By the width to each little image
Compare with default edging quality standard, thus judge the edging mass effect of overall glass.
D. judge that little image, whether in regulation interval value, is marked by the width measurement of little image according to judged result
Know.
Further, described it is identified specifically including by little image according to judged result: if the width of little image is surveyed
Little image in regulation interval value, is then designated as green by value, if the width measurement of little image is not in regulation interval value,
Then little image is designated as yellow, if continuous 4 little images are yellow, then these continuous 4 little images is designated as redness.Further
, described green expression is qualified, and red expression is defective.
The LCD glass fragment of each detecting position detection 6mm length, the edging edge image that the most described shooting obtains is a length of
6mm.The LCD glass of general a piece of a length of 200mm, can detect in 3 seconds.Detection beat can coordinate productive temp,
Line is carried out, it is achieved the full inspection to glass with edger unit.
In the present embodiment, the image-forming principle of LCD glass edging is: due to edging operation, to destroy the minute surface of glass edge anti-
Penetrate state, therefore this device arrange when LCD glass 4 edge is illuminated by two angle light sources 3 up and down, LCD glass 4 is not
The part of edging will produce direct reflection to light, by controlling the angle of light source 3, LCD glass 4 non-edging part can be made big
Part luminous reflectance is to outside imaging system, and LCD glass 4 edging part, has been ground as roughened state due to surface, thus to light
The light in source 3 produces diffuse-reflectance, makes the light of part can be reflected into imaging system, thus obtain in imaging systems higher right
Ratio degree image.
Advantage of this embodiment is that: 1.LCD glass edging contrast is high, and imaging precision is good；2. accuracy of detection is high, can be right
LCD glass edging is accurately measured, and the edging can with projection or pit is accurately measured；3. adopt
With Aulomatizeted Detect, work efficiency is high.
