Problems solved by technology

This method has high calibration accuracy, but it cannot achieve real-time online calibration, and in the process of installing the micro-gripper on the micro-motion platform for the second time, due to the difference in the fixing method, errors are introduced, which reduces the micro-grip. Clamping accuracy of the clamp

Embodiment Construction

[0031] as attached figure 1 , the micro-clamp of the present invention includes a mounting plate 1, a pre-tightening screw 2, a micro-clamp body 3, a semicircular gasket 4, a driving device 5, a set screw 6, a first strain gauge 7, a second strain gauge 8, the end jaw 9 is formed. The micro-clamp main body 3 is fixed and assembled by the set screw 6 and the mounting plate 1, and the two strain gauges are bonded to the micro-clamp main body 3 by epoxy glue, and the position status of the probe at the end of the micro-clamp is output in real time. The driving device 5 adopts piezoelectric ceramics manufactured in a stacked manner. One end is fixed on the micro-clamp body 1, and the other end is in contact with the semicircular gasket 4 to transmit the generated displacement to the main structure of the micro-clamp. The micro-clamp is designed to be left-right symmetrical to realize a piezoelectric drive to realize the simultaneous displacement of the probes on both sides, furth...

Abstract

The invention provides a manufacturing method for a piezoelectric microgripper. The piezoelectric microgripper can move in a long stroke and has a compact structure at the same time, meanwhile, basedon the microscope environment of microoperation, through the manufacturing method, on-line calibration of the microgripper is achieved conveniently, preparation time in the microoperation process is shortened, workloads are reduced, and the microoperation efficiency is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a micro-clamp, in particular to a method for manufacturing a piezoelectric micro-clamp suitable for micron-scale applications, and belongs to the technical field of micro-operation and micro-assembly. Background technique [0002] At present, micro-manipulation and micro-assembly technologies are widely used in research fields such as micro-electro-mechanical systems, special pipeline matching, bioengineering, and electronic packaging of small components. Among them, the micro clamp is an indispensable and important device in the device assembly process, mainly used to realize the clamping, moving, releasing and other operations of micro objects with a diameter of less than 200 microns. [0003] A microgripper is usually composed of a driving device and a displacement transmission device. At present, the commonly used driving methods of micro grippers include electrothermal drive, electromagnetic dri...
