When multiple optical sensors work together, the application of multiple sensors in the quality control link of Kleiner stamping technology company, Kleiner stamping technology independently designs and manufactures tools for the production of precision stamping products. This is of great significance to the quality of the parts they produce. Werthvideocheckha has a variety of optical sensors that can adapt to different measurement tasks, which provides accurate measurement results for building 3D high-definition shapes of tools and parts. When multiple optical sensors work together, the application of multiple sensors in the quality control link of Kleiner stamping technology company comes from J ü rgenf ä ß ler of the quality pre qualification Planning Department of Kleiner company (left) and detlef ferger, sales director of Weide Measurement Technology Co., Ltd., are discussing an example of multi-sensor applications. From micro stamping parts, springs, door bolts to assembled lead frames, Kleiner Co., Ltd. in Pforzheim specializes in producing such precision stamping parts. These stamping parts are used in all walks of life, such as automobile, plastics, electrical In the pharmaceutical and electronic industries. The company takes meeting the needs of customers as the policy, and their purpose is: 'what customers value is quality.' Because the quality of the parts produced is largely determined by the precision of the tools, and good quality is not obtained by chance. Therefore, Kleiner, a certified stamping expert, has set up a high-performance tool workshop and an advanced quality planning system. Multi-sensor technology is applied to complex 3D measurement. The task leader spent more than a year looking for a suitable solution. They measure samples, analyze data, and evaluate different machines for flexibility, accuracy, and software used. 'We have found all the performance required to complete our tools on the composite CMM videocheckha of Weide Measurement Technology Co., Ltd. its high precision and the diversity of multi-sensor technology applications make our three-dimensional measurement problems solved.' F äß ler added, 'for us, what is different is the combination of nm focusing sensor NFP and Weide optical fiber sensor WFP. This enables us to measure the three-dimensional surface of etching electrodes of small embossing, embossing die and embossing die insert at one time in a short time. Other suppliers cannot complete this task.' Establish a reliable partnership with Weide. The employees of Kleiner company have long been familiar with Weide measuring machine. The innovative Taiwan Weide measuring machine inspector purchased by Kleiner in the 1990s is still satisfactory. Therefore, the quality assurance department with 12 employees decided to purchase the measuring equipment of Weide company for measuring and testing parts and tools this year. This includes one flatscope, one scopecheck and two videocheck The new videocheckha400 for tool technology measurement has a measurement range of 400mmx400mmx200mm. The tolerance of tools and tool components is within microns. The error of stamping parts is within a few millimeters. Accuracy of measurement results (determined by the measurement uncertainty) it should be 5 times less than the tolerance. Following this principle and maintaining the consistency of the measurement results between production and R & D, Kleiner chose Weide's high-precision videocheckha measuring machine. The stable mechanical structure consists of hard granite, special low vibration air floating block, high positioning resolution and structural measures to reduce lag Yes. The error of the measurement results is controlled to be less than 1 μ m. Its repeatability is controlled at the micron level. Kleiner's metrology personnel reached a consensus on the selection of sensors. They selected image processing sensors and laser sensors integrated in the optical path, as well as nm focusing sensors NFP and Weide optical fiber probe WFP The workpiece can be rotated at any angle through an additional turntable. New high-precision three-dimensional measurement technology for copper electrode, embossing and embossing die and embossing punch die helps Kleiner optimize the quality of tools and production parts. 20% of the measurement tasks are used to measure and detect copper electrodes made by high-speed milling. The copper electrode will form a contour and embossing pattern on the alloy embossing and embossing die by corrosion in the next working step. When multiple optical sensors work together, the application of multiple sensors in the quality control link of Kleiner stamping technology company measures the embossing punch through nm focusing sensor. The measurement results will be compared with the theoretical data in the CAD system, and the deviation will be displayed by color coding. The optical fiber probe is used to measure the vertical plane. In order to obtain the data of the embossed side, WFP can be used for point measurement. The obtained microprobe consists of glass fiber. At its end there is a small diameter of only 20 μ M probe ball. Different from the traditional probe dot measurement, the optical fiber probe completes the measurement through the combination of contact and optics. In other words, the probe balls are only used as contact AIDS, and their position changes are determined by optics. Because the probe ball is fixed on the glass fiber, its contact force is small. The detection deviation is only within a few tenths of a micron. Similar to the traditional probe, the software calculates the corresponding measurement points on the part surface through the probe ball radius. When multiple optical sensors work together, the application of multiple sensors in the quality control link of Kleiner stamping technology company, the measurement points collected through the optical fiber probe and the plane information obtained through the nm focusing sensor constitute a complete report on the quality of parts. All measurement data can be compared with 3D design data through measurement software winwerth. Through the expression form of color coding, people can see the contour deviation at a glance. Weide 3D videocheck machine with turntable can provide a measurement expansion function. Through the rotation of nm focusing sensor and turntable, the parts can be measured with high resolution at any angle. 'We use this function in many places, and the results are very good. The imprinted side does not need too high-resolution data. Through the optical fiber probe, we can quickly and accurately collect the measurement points at important positions.' Just like every Weide CMM, videocheckha and the loaded image processing sensor are also suitable for two-dimensional measurement. Without a measurement task, kaubert of Kleiner will help his colleagues with the first piece measurement. Back in the past, Weide's multi-sensor technology ensured the data fusion from optical sensor WFP and nm focusing sensor, which played a positive role in improving the product quality of precision stamping parts of Kleiner company.
