Advantages and applications of non-contact color detection system

overview

traditional color detection systems use contact non-contact method to detect the color of products. The so-called contact type means that when detecting color, the product or sample must be in close contact with the measuring instrument, otherwise accurate color data will not be obtained. For non-standard detection, the product needs to be removed from the production line for detection, so the real-time color data on the production line cannot be obtained in time

in contrast, the non-contact color detection system keeps a certain distance between the product and the detection instrument when carrying out color detection, and can also directly detect the product on the production line. The parameters such as elastic modulus, elongation, constant elongation stress, constant stress elongation, constant stress contraction break through the limitations of traditional color detection methods

generally, the non-contact color detection system includes color detection instruments, control software and auxiliary equipment. Color detection instruments are mainly used to detect products to get the original data of color. Software is mainly used to control instruments and analyze data. Auxiliary devices are used to assist in the realization of specific functions. For example, warning lights are used to display the color status of products. When the red light flashes, it indicates that the color difference of the color is too large

advantages of non-contact detection

traditional color detection requires a certain amount of pressure on the surface of the tested product, but this often causes certain damage to the product. In contrast, because the non-contact color detection allows the product to maintain a certain distance from the instrument, it will not cause damage or damage to the product or sample

the non-contact color detection system can detect non planar products. Although with the help of some fixtures, the traditional detection system can also detect some non planar products, the accuracy of this detection method is not satisfactory. Obviously, the measurement range of the non-contact detection system is much broader, and the accuracy and precision of the detection have also been greatly improved

generally, when testing granular and powder products such as color masterbatch, instruments need to be tested through glass. Due to the limitation of measurement area, the uncertainty of particle arrangement and the influence of glass, the repeatability of measurement is often not guaranteed. Non contact measurement can avoid the influence of containers. At the same time, due to the larger measurement area, it can also significantly weaken the influence of product arrangement on the measurement results, so it is easier to obtain accurate color data

in addition, the non-contact detection system can also detect wet samples, such as wet paint scraping samples. Traditional instruments are difficult to measure this kind of wet sample, because direct measurement will pollute or even damage the instrument. This problem does not exist in non-contact measurement

advantages of detection

detection can monitor the quality of products on the production line in real time and enhance the color adhesion, which is not only conducive to reducing production waste, but also can effectively improve production efficiency. Here, there are two meanings: one is that the detection system is installed on the production line, and the other is that the detection system is connected with the control system of the production line

traditional color detection usually lags behind production. When the product is detected to have color problems, many or a large number of unqualified products have been produced, which leads to the waste of materials, and testing can overcome this shortcoming. For example, in the production process of building profiles, the product detection system can be installed on the extruder. When the product reaches the detection position or the set time limit, the detection system will automatically detect the color of the product and obtain real-time color data in time. In this way, before cutting the product, you can master the advantages and disadvantages of the product color in detail, and you can adjust it immediately if there are problems. In the process of testing, the products do not need to leave the production line or stop the production of the production line. Therefore, time and labor costs are greatly saved

connect the detection system with the control system of the production line to form a closed-loop control system. When the color data does not meet the requirements, the detection system can send a warning to the control system, or even stop production directly. The detection system installed on the fireproof board production line is a successful application case. When the deviation of product color exceeds the warning value, the system will send a warning to the relevant departments. If the error of the product exceeds the allowable range, the system will automatically send instructions to transfer the unqualified products on the production line to a specific area

another advantage of connecting with the control system of the production line is that the color data can be monitored remotely. Production management personnel or quality management personnel can monitor the color of products in the office, or directly issue relevant orders and instructions through the control system. The traditional color detection system needs to use e-mail or other means to manually convey the quality of color, which is time-consuming and laborious, and the accuracy is poor

vericolor spectro non-contact detection system

vericolor spectro non-contact detection system developed by aseli is such a detection system that can realize high-quality measurement, and is economical and practical. The successful development of the detection system also creates conditions for the wide application of non-contact detection system in plastics and other industries

this system includes vericolor spectrophotometer and vericolor spectro software. Among them, the spectrophotometer is 0/30 lighting measurement geometry, using full spectrum LED lighting, the measurement area is 25.4mm, the average inter platform difference is 0.3de*, and the weight is only 2.81kg. Veri is as shown in the figure. The load sensor is installed on the 10 prefix and the fixture used to clamp the experimental piece. The color spectrum software is based on the windows operating system. It is easy to install, the interface is simple, and the generated data can be recorded in the form of Excel files

Later, he developed various types of fatigue testing machines, and carried out fatigue tests with metal samples for the first time.

the system uses double beam 31 channels, which has high accuracy, and the average short-term repeatability is only 0.03de*. Due to the patented light source design, the system is insensitive to ambient light such as incandescent lamps, fluorescent lamps and sodium lamps, and there is no need to change the lighting conditions of the factory. The working temperature range of the system is 0~50 ℃, the measurement distance is 10.16cm, and a deviation of 5.0mm is allowed. Therefore, it is less affected by distance fluctuation. It is worth mentioning that the system has passed the nema-4/ip67 standard audit, which can prevent dust and pollution, and can withstand impact and vibration. In addition, the system is not only solidly designed, but also easy to maintain. There is almost no need to do special maintenance. It only needs to make the tension on the strip or the pressure on the PCU help control the activities within the allowable range of the spine for daily cleaning and monthly correction
