In contrast, the non-contact online color detection system maintains a certain distance between the product and the detection instrument when performing color detection, and can also directly detect the product on the production line, which breaks through the limitations of traditional color detection methods.
In general, non-contact online color detection systems include color detection instruments, control software, and auxiliary devices. The color detection instrument is mainly used to detect the product to get the original data of the color. The software is mainly used to control instruments and analyze data. Auxiliary equipment is used to assist in achieving specific functions. For example, a warning light is used to display the product's color status. When the red light is flashing, 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 product being tested, but this often results in some 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 damage or damage the product or the sample.
Non-contact color detection systems can detect non-planar products. Although some conventional non-planar products can be detected by conventional inspection systems with the help of some fixtures, 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 accuracy of the detection have also been greatly improved.
In general, when testing particulate and powder products such as masterbatch, the instrument is required to pass through the glass for detection. Due to the limitations of the measurement area, the uncertainty of the particle arrangement and the influence of the glass, the repeatability of the measurement cannot always be guaranteed. The non-contact measurement can avoid the influence of the container. At the same time, due to the larger measurement area, the influence of the product arrangement on the measurement result can be significantly weakened, so that accurate color data can be more easily obtained.
In addition, the non-contact detection system can also detect wet samples, such as dry paint scratches. Traditional instruments are difficult to measure with this wet sample because direct measurements can cause contamination or even damage the instrument. Non-contact measurement does not have this problem.
Advantages of On-Line Detection Online detection can monitor the quality of products on the production line in real time and enhance color adhesion, which not only helps reduce production waste, but also effectively improves production efficiency. Here "online" contains two meanings: First, the detection system is installed on the production line; second, the detection system is connected to the control system of the production line.
Traditional color detection usually lags behind production. When a color problem is detected in a product, many or a large number of unqualified products have been produced, which in turn leads to waste of materials, and on-line inspection can overcome this disadvantage. For example, in the production of building profiles, the product inspection system can be installed on the extruder. When the product reaches the detection position or reaches 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 learn in detail the pros and cons of the product color, and if any problems can be adjusted immediately. In the inspection process, products do not need to leave the production line and do not stop the production of the production line. Therefore, the time and labor costs are greatly saved.
Connecting the inspection system with the control system of the production line can form a closed-loop control system. When the color data does not meet the requirements, the inspection system can warn the control system and even stop production directly. The detection system installed on the fire board production line is a successful application case. When the product color deviation exceeds the alert value, the system will issue a warning to the relevant department. If the error of the product is beyond the allowable range, the system will automatically issue instructions to transfer the unqualified product on the production line to a specific area.
Another benefit associated with the production line's control system is the remote monitoring of color data. Production management personnel or quality management personnel can monitor the color of products in the office, and can also directly issue relevant command instructions through the control system. The traditional color detection system requires the use of e-mail or telephone to manually communicate the quality of the color, which is time-consuming and laborious, and the accuracy is also poor.
VericolorSpectro non-contact on-line detection system Versacolor Spectro's VericolorSpectro non-contact on-line detection system is such a high-quality measurement, and economical and practical detection system. The successful development of this detection system also created conditions for the wide application of non-contact online inspection systems in plastics and other industries.
The system includes the VericolorSpectro spectrophotometer and VericolorSpectro software. Among them, the spectrophotometer is 0/30 lighting measurement geometry, using full-spectrum LED lighting, measuring an area of ​​25.4mm, the average difference between the bench is 0.3DE*, weighing only 2.81kg. VericolorSpectro software is based on Windows operating system, easy to install, easy to interface, and the generated data can be recorded in the form of EXCEL files.
The system uses dual-beam 31-channels with high accuracy, with an average short-term repeatability of only 0.03 DE*. Thanks to the patented light source design, the system is insensitive to ambient light such as incandescent, fluorescent and sodium lamps, without changing the lighting conditions of the factory. The operating temperature range of the system is 0~50°C, the measuring distance is 10.16cm, and the deviation of ±5.0mm can be allowed. Therefore, the influence of distance fluctuation is small. It is worth mentioning that the system has passed the NEMA-4/IP67 standard audit, can be dust-proof, anti-pollution, and can withstand shock and vibration. In addition, the system is not only robust in design, but also easy to maintain, requiring little or no special maintenance, but only daily cleaning and monthly calibration.
The advantages and applications of non-contact online color detection system
Overview Traditional color detection systems use a contactless, off-line method to color detect products. The so-called contact type means that when the color is detected, the product or sample must be in close contact with the measuring instrument. Otherwise, accurate color data cannot be obtained. Non-online detection requires the product to be removed from the production line for testing, and thus cannot obtain real-time color data on the production line in a timely manner.
