Cutting-edge advancements and application prospects of contactless high-speed injection valve technology

I. Overview of Non-Contact High-Speed Jet Valve Technology

Non-contact high-speed jet valve technology is an advanced manufacturing technology based on the principle of non-contact dispensing. Compared with traditional contact dispensing technology, non-contact high-speed jet valve technology does not rely on surface tension to draw glue from the nozzle, but uses the high fluid momentum generated in the jet valve to quickly inject a certain volume of glue onto the target. This technology eliminates the need for the dispensing valve to move along the Z-axis, avoiding direct contact with the workpiece, thereby improving dispensing accuracy and speed.

Non-contact high-speed jet valve technology can be divided into pneumatic drive jetting technology and piezoelectric jetting drive technology according to different drive methods. Pneumatically driven jet valves use pressure changes to generate jetting force and are suitable for a variety of fluid materials. Piezoelectrically driven valves use the inverse piezoelectric effect of piezoelectric ceramics to achieve high-speed and high-precision dispensing by precisely controlling voltage changes.

II. Latest Advances in Non-Contact High-Speed Jet Valve Technology

In recent years, non-contact high-speed jet valve technology has made significant progress in several aspects. First, in terms of dispensing speed, non-contact high-speed jet valves have achieved dispensing speeds as high as hundreds or even thousands of glue points per second, greatly improving production efficiency. Second, in terms of dispensing accuracy, through the optimization of the design and manufacturing process of the jet valve, non-contact high-speed jet valves have been able to achieve glue point sizes as small as a few nanoliters, and the tolerance is controlled within a very small range. In addition, non-contact high-speed jet valves also have advantages such as high flexibility, low maintenance cost, and long service life, allowing them to maintain stable performance under various complex and harsh working conditions.

In terms of technological innovation, some advanced non-contact high-speed jet valves have also integrated intelligent and automated elements. For example, by integrating sensors and control systems, non-contact high-speed jet valves can monitor and adjust dispensing parameters in real time to ensure the consistency and stability of dispensing quality. At the same time, combined with machine vision and artificial intelligence technology, non-contact high-speed jet valves can also achieve more complex dispensing patterns and shapes to meet more diverse production needs.
