Detailed description of the invention
Fig. 1 is product size on-line measuring device structural schematic diagram.
In figure: 1- camera；2- product identification code；3- test product；4- production line；5- alarm；6- electric control operation
Cabinet；61- display screen；62- industrial personal computer；7- light source；The first code reader of 8-；9- photoelectric sensor；10- light barrier.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
The utility model relates to product size on-line measuring device for being examined to product size in production line
It surveys, is particularly suitable for online dimensional measurement and the inspection simultaneously of the even special-shaped plate of variety classes and size.
Product in the utility model posts product identification code, and product identification code can be bar code or two dimensional code, product
Identification code is stored with the number of mark product identification information and the design size information of product, can also only storage number believe certainly
Breath, the number information that industrial personal computer is read according to code reader transfer the design size information of product out of background data base.
Such as Fig. 1, product size on-line measuring device includes setting gradually from front to back along production line transmission direction
Camera 1, photoelectric sensor 9 and the first code reader 8 above production line.Wherein high speed linear CCD can be used in camera 1
Camera, sample rate reach 80K or more, the multiple groups dimension data of plate difference section can be obtained, so that measurement result is more accurate
Reliably, and the quantity of CCD camera can be multiple.Photoelectric sensor 9 detects in production line whether have product process.The
One code reader 8 is used to read the identification code 2 on product.
The two sides of camera 1 have one group of parallel light barrier 10, and light barrier 10 extends to production line direction.
With the gap of straight-on camera 1 in production line, the gap is laterally arranged, hangs down with pipeline direction
Directly.Production line is divided into two parts by the i.e. described gap, and there is corresponding drive system in every part.Light is equipped in the gap
High-brightness LED, the width not less than production line of light source 7, when so that product passing through the gap can be used in source 7, light source 7
Part light-illuminating is in product bottom.Image is acquired in the mode of test product back (bottom) polishing in imaging process, in this way
Product area shows black, and background parts are shown as white, eliminate color, texture of this product itself of plank etc. to detection
Caused by interfere, while also evaded sought caused by plate edge band and plate gray difference itself side interference, effectively increase
Detection accuracy.
Product size on-line measuring device includes industrial personal computer 62, and industrial personal computer 62 connects camera 1, alarm 5, light source 7, first
Code reader 8, photoelectric sensor 9, control each device, realize the detection to product size.It is detected in photoelectric sensor 9
Signal is sent to industrial personal computer 62 to when having product to pass through, then first code reader 8 of the starting of industrial personal computer 62 reads the product identification
Code obtains the standard size information of product；When product moves forwards 1 underface of camera, camera 1 obtains the image letter of product
Breath, industrial personal computer 62 are handled image by image processing software, calculate the actual size of product；Industrial personal computer 62 will be practical
The design size that size and scanning product ID obtain, which compares, calculates error amount, industrial personal computer control when error is more than threshold value
5 alert of alarm processed, wherein alarm 5 is audible-visual alarm lamp.
Display 61 shows following at least one information: number, actual size, standard size and the scale error of product.
Wherein, display 61, industrial personal computer 62 and input equipment (keyboard and mouse etc.) are encapsulated in electric control operation cabinet 6.
The product size on-line measuring device of above-described embodiment may be abnormal situation, example in testing product size
After reading the identification code of product such as the first code reader 8, worker may take product away before the detection of camera 1, so that camera 1
It is unanimously in standby, or even the image of next product is mistaken for being image that worker takes product away, cause detection mixed
Disorderly.In order to avoid such case, industrial personal computer 62 connects the second code reader, and second code reader is not provided in production line,
Such as can be held by worker, when worker takes the product identified by the first code reader 8 away, second reader is aligned
The identification code is read again once, and industrial personal computer 62 is abandoned after detecting the information that second reader is read to the product
The detection of the size of product corresponding to identification code.
