After many years of development, the nozzle technology of SMT machine has been able to meet the needs of SMT production. But due to the application of 0201and 01005 small parts, nozzle material is getting smaller and smaller to take some new challenges to processing. Now, generally used nozzle materials and processing methods aren’t perfect. For example, Diamond nozzles aren’t real, but complex mixture of diamonds and metals. The air inlet of Zirconia is high, and the hardness of the metallized material is large, if not used properly fragile and easy to break.The suction port of PVD coating is subjected to considerable heat during the coating process and requires a strict cleaning process, especially when the suction port is a small hole, improper coating will cause the hole to clog. Steel tool is not only difficult to process, but also expensive.
In fact, the part requiring high wear resistance of the nozzle is only the end of the nozzle in contact with the component. The use of easily processed and low cost materials, and treatment on the end surface is an important idea to solve the nozzle head problem. The applied materials and processing ways as well as detection methods are the key technology. At present, there are has been nozzle products that using this method.
The nozzle is based on aluminum alloy as the nozzle, and the front end is surface treated by electrophoretic ceramic molding technology (Figure D). Electrophoretic molding uses the movement of ceramic oxide particles charged in an electric field to form higher dense layers. Because of the dense structure of this layer, it is possible to form low-defect ceramics on complex surfaces.The electrophoretic ceramic forming technology can generate a uniform stacked layer of ceramics with a thickness of more than ten microns on the suction end of the processed aluminum alloy in just a few minutes to achieve a good bond with the aluminum alloy. Guangdong R-Yangling electronics mainly sells SMT sealing machine accessories, nozzle, bearings, cylinders, sensors, steel wire/plate/black belt, consumables and supporting equipment. If you need, please consult online customer service.
Nozzle of the alloy to produce porcelain, scanning electron microscope microstructure examination and various performance tests, indicating a high performance product, which quality of the surface and anti-occlusion, color, nozzle life, to satisfactory level, however in the actual test, simulated 3 million times, after the end of contact, scanning type power Miller nozzle observation and didn’t find significant wear and breakage; In the medium production volume of the workshop test was carried out for more than 18 months and showed good performance without failures.
