Abstract
The invention discloses a detection method for stain on appearance of modified plastic, which comprises the following steps: 1)the modified plastic particles are prepared to a flat plate, and is placed in a sealing system formed by a black box; 2)the light source is used for providing illumination to the flat plate, and a camera is used for shooting the image of the flat plate; and 3)stain identification is carried out on the image of the flat plate, and the identified stain is performed classified statistic. The detection method for the stain on the appearance of the modified plastic is characterized in that by shooting the image of the flat plate prepared by the modified stain, and performing stain identification and classified statistic of the image, artificial subjectivity can be avoided, and the stain number and the stain size can be accurately recorded, the image of the flat plate can be stored for being as a record, so that the storage and occupation space of the object can be avoided.
Description
Technical field
The present invention relates to a kind of modified plastics outward appearance smear detecting method.
Background technology
Modified plastics is often used on the shell body of product, generally by injection machine, modified plastics particle is injection molded into plate.Because the profile General Requirements of product is very high, especially light color shell body, such as the shell of electric cooker, the shell of air-conditioning etc., therefore modified plastics particle needs its outward appearance stain to detect after being injection molded into plate, detects whether its outward appearance has a stain, the size of stain is how many and stain number is how many etc.
At present, general modified plastics appearance detecting method is only visual observations, because people's subjective sensation impact is very large, thereby the accuracy detecting is had a great impact.The stain state that cannot represent plate face simultaneously when recording result, must store just to enter to preserve by material object, very inconvenient.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of modified plastics outward appearance smear detecting method, solved a detection difficult problem for outward appearance stain in existing modified plastics production run.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of modified plastics outward appearance smear detecting method, comprises the following steps:
1. modified plastics particle is made to flat board, and be positioned in the sealing system of black box formation;
2. with light source, provide illumination for described flat board, and with camera, take the image of described flat board;
3. the image of the described flat board of taking is carried out to stain identification, and the stain of identification is carried out to statistic of classification.
As a further improvement on the present invention, described step 1. in, described flat board is positioned on the mobile platform in described black box.
As a further improvement on the present invention, described step 2. in, described light source is multi-point source.
As a further improvement on the present invention, described step 2. in, the described lithograph picture of shooting is multiple.
As a further improvement on the present invention, described step 3. in, the image of the described flat board of taking is carried out to stain identification by colour (L, a, b).
As a further improvement on the present invention, described step 3. in, according to stain diameter or stain area, stain is carried out to statistic of classification.
The invention has the beneficial effects as follows: the dull and stereotyped image that this modified plastics outward appearance smear detecting method is made by taking modification stain, and this image is carried out to stain identification and statistic of classification, avoided artificial subjectivity, can record clear, accurately the number of stain and the size of stain, can look like to store as record to lithograph, avoided storage in kind to take up room simultaneously.
Accompanying drawing explanation
Fig. 1 is blot detecting system structural representation described in the embodiment of the present invention.
Embodiment
By reference to the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, the simple equivalence of in every case being done with the present patent application the scope of the claims and description changes and modifies, within all still belonging to patent covering scope of the present invention.
As shown in Figure 1, be a kind of structural representation of modified plastics outward appearance blot detecting system, it is comprised of computer 1, black box 2, Quadratic Finite Element scanner 3 and mobile platform 4.Wherein, black box forms a totally-enclosed system, and camera, light source, mobile platform and flat board are all sealed in it, avoids external light source to disturb, to take, forms stable light source, ever adds Repeatability and Reproducibility.
When in use, system detects modified plastics outward appearance stain, can carry out according to following steps, first the modified plastics particle of having produced is injection molded into flat board by injector, this flat board is positioned on mobile platform 4, on computer 1, set the enlargement factor of Quadratic Finite Element scanner 3, and can adjust as required the magnifier multiple of this Quadratic Finite Element scanner 3, then by black box 2 sealings, (it is following that light source can be arranged on the camera of Quadratic Finite Element scanner to open suitable multi-point source or light source board, or be arranged on the periphery of inner wall of black box 2), under the movement of mobile platform, scan successively dull and stereotyped different parts, with professional image processing software, captured Local map is spliced into complete lithograph, and store, so that visual, transfer and add up.During statistics, can manually put the colour of getting in image as basic point, and manually set L ± 0.3, a ± 0.3, the pigment of b ± 0.3 is as the edge line of stain, and statistic diameters is greater than the stain number of 0.5mm thus, thereby judge whether to meet the demand of product quality, and do not need to use artificial visually examine.
Claims (6)
1. a modified plastics outward appearance smear detecting method, is characterized in that, comprises the following steps:
1. modified plastics particle is made to flat board, and be positioned in the sealing system of black box formation;
2. with light source, provide illumination for described flat board, and with camera, take the image of described flat board;
3. the image of the described flat board of taking is carried out to stain identification, and the stain of identification is carried out to statistic of classification.
2. modified plastics outward appearance smear detecting method according to claim 1, is characterized in that: described step 1. in, described flat board is positioned on the mobile platform in described black box.
3. modified plastics outward appearance smear detecting method according to claim 1, is characterized in that: described step 2. in, described light source is multi-point source.
