New technology in the precision component industry
The most important part of the finest electronic components, how to complete the precision assembly by clamping, is a very serious problem. Professor Wang Minghe, a professor of mechanical engineering at a university, developed the "non-contact ultrasonic acoustic floating clamping system", which can effectively clamp fine and delicate components. This research is unique in China and will be applied in the fields of optoelectronics and semiconductors.
The development of science and technology is changing with each passing day, and the manufacture of components tends to be high-precision and minimized. The "non-contact ultrasonic acoustic floating clamping system" announced by Chengda yesterday is the first research achievement in China.
Wang Shenghe said that clamping small components is the most important task in precision assembly. The clamping process includes the actions of clamping, lifting, carrying, placing and releasing. However, during the clamping process, the clamping force is often difficult to control. The wear and dirt on the surface of the clamped object may also cause the accuracy of micro-assembly and the yield of the product to decrease due to the viscous phenomenon.
In view of the fact that the traditional acoustic floating research is mainly based on the uniaxial standing wave type acoustic floating mechanism, it is susceptible to disturbance by other directions. Wang Shenghe uses a tilting acoustic floating structure to allow objects to be suspended in the sound field and transported, and various components are transported. Such as water-like liquid, flying rice laser, dust, etc. can be non-contact clamping, can be applied in the fields of optoelectronics, semiconductor, micro-electromechanical process, composite materials, and biomedicine.
