Chip capacitors, full name: multi (laminated, laminated) chip ceramic capacitors. Chip capacitors are used in almost all electronic products, and completely replace the plug-in capacitor is also a trend in the future. However, as electronic products become smaller, so the chip capacitor size has more stringent requirements. For the same electrical characteristics of the capacitor requirements are also increasing, especially in the length of the capacitor polarity side molding, will directly affect the final quality of the capacitor. However, due to the special nature of chip capacitor production process, making it in the production of molding, the capacitor electrode has been unable to use the manual for accurate measurement. So most of the major capacitor production capacity by improving the precision molding equipment, and the size of the basic right after forming testing. As a result the total cost of the equipment is not only improved, but also the range of molding can not guarantee to meet the requirements of the size, thus seriously affecting the pass-through rate of the product. Christie (CST) self-developed automatic visual inspection system chip capacitors, chip capacitor electrode to detect the size and appearance of the measurement process is completely avoided intervention, to achieve high efficiency, high repeatability, high-reliability detection measurement processes. And detection system embedded directly onto the chip capacitors existing production lines, to ensure that the capacity of the production line capacity to meet growing market demand. System Configuration: Visual Software: CST chip capacitors visual inspection system vision hardware: CST visual light, light controllers, industrial monochrome CCD camera, industrial fixed focus lens low distortion and other moving parts: PLC, industrial PC, motion control cards and other control components : Chip capacitors forming electrical control system detects content: SMD capacitor electrode length (maximum, minimum, the difference between the two). Chip capacitor electrode forming appearance detection. Performance indicators: detection speed (the visual part) Average 8Pcs / s chip capacitor electrode within the measurement accuracy of ± 0.01mm, forming the appearance of repeat accuracy of ± 0.005mm chip capacitor electrode forming whether the recognition rate of 100% chip capacitor electrode Do defect rate of 99.7% system functions: real-time display test results, real-time measurement data is saved. Management process parameters, the parameters can be set and saved detect a variety of specifications of products with statistical functions, such as defective product type, quantity and the passing rate, with the SPC statistical analysis system stability, repeatability higher
