Problems solved by technology

The early piezoelectric ceramic drive has a complex drive structure, large size, large motion scale, and large drift. Now the piezoelectric ceramic linear motor is small in size, high in precision, and large in motion range. Therefore, nano manipulators driven by piezoelectric ceramic motors are The most convenient way to achieve nanomanipulation

According to the device, through combination of an X-direction piezoelectric ceramic linear motor, a Z-direction piezoelectric ceramic linear motor and a Y-direction piezoelectric ceramic rotary motor, micro / nano operation at the nano-scale accuracy within the large range from nano-scale to centimeter-scale can be achieved, independent or simultaneous three-freedom-of-degree control is achieved, accuracy is high, and the problems that a micro / nano operating device is small in operating range and single in adaptability are solved; the device can be used for precise operation of electron microscopes, optical microscopes and the like, and micro / nano operation such as alignment, injection, electric signal application and cutting is conducted; and the device is simple in structure and small in size.

Description

technical field [0001] The invention belongs to the technical field of micro-nano operating devices, and in particular relates to a micro-nano operating device with small volume, high precision, large motion range and wide applicability. Background technique [0002] The surface morphology of materials can be observed by optical microscope or electron microscope, and its resolution can reach micron and nanometer level. While studying the surface morphology of materials, in recent years, material researchers have paid more and more attention to the observed micro-nano materials, using micro-manipulators for manipulation and testing and research of mechanical and electrical properties. [0003] There are only a few companies in the international market for micro-manipulation devices for scanning electron microscopes, such as KleindickKanorochnik, KlockeNanotechnik, Omiprobe, and Zyvex, whose step size reaches the nanometer level; there are also researches in China, such as Lan...
