Abstract

The invention discloses a microoperation device and method based on the capillary force and belongs to the technical field of microoperation. A liquid drop generation mechanism, a moving operation mechanism and a top view mechanism are all arranged on a vibration reduction table. The influence of external vibration on operation of the micro device can be reduced by operating on the vibration reduction table, so efficient and high-precision picking, transferring and releasing of the micro device are completed under the action of capillary force. A micro propelling pump, an industrial camera anda three-dimensional electric displacement platform can be integrally controlled through a computer, and automatic control over the operation process of the micro device can be achieved, the micro-operation device based on the capillary force is simple in structure, capable of achieving automatic control, convenient to operate and easy to achieve industrial production.

Description

technical field [0001] The invention belongs to the technical field of micro-operation equipment, and in particular relates to a micro-operation device and method based on capillary force. Background technique [0002] With the emergence of smart devices and wearable devices, the development of electronic products in the direction of miniaturization, multi-function and flexibility has been further promoted, and people have also put forward higher and higher requirements for the quality of electronic products. However, due to the scale effect, the operation of microdevices becomes very challenging. At present, common micro-manipulation technologies are mainly divided into contact and non-contact: contact micro-manipulation methods are based on piezoelectricity, vacuum, etc. Non-contact micro-manipulation methods are based on field forces, such as electric fields, magnetic fields, light, and sound waves. [0003] However, in the prior art, the contact micro-manipulation meth...
