Multi-micro part coplane adjusting platform and method based on microscopic vision depth of field

Abstract

The invention discloses a multi-micro part coplane adjusting working platform and a corresponding method based on one-way microscopic vision. The platform comprises a motion platform A, a motion platform B, a microscopic vision system, a holder base, a pitching platform, a holder, micro parts and a computer. The method comprises the following steps that firstly, the microscopic vision system is adjusted to a maximum visual field, and the micro parts are adjusted into the visual field so as to form a clear image; then the image is processed to obtain the positions of the parts in the image, and the motion amount that the parts are moved to the holder in the center of the visual field is obtained through computation; finally, some micro part is moved to the center of the visual field, the vision system is adjusted to a minimum visual filed, the part is precisely focused, then the other parts are moved to the center of the visual filed in sequence, and all the parts form clear images in the vision system. The multi-micro part coplane adjusting working platform and the corresponding method based on one-way microscopic vision have the advantages that micron dimension coplane adjustment precision is realized, the method is simple and easy to carry out, and the execution efficiency is high.

Description

technical field [0001] The invention belongs to microscopic vision measurement and control in the field of micro-assembly technology, in particular to a coplanar adjustment platform and method for multi-miniature parts based on microscopic vision depth of field. Background technique [0002] With the rapid development of micro-electro-mechanical systems, the assembly process tends to become more complicated, often involving the coplanar adjustment of multiple tiny parts in a certain two-dimensional plane. The advanced coplanar adjustment technology of multiple micro-parts is of great significance for shortening the production cycle of micro-miniature products and reducing costs. At the same time, microscopic vision is widely used in micro-assembly. Based on the particularity of the fiber vision system, this invention utilizes the characteristics of the small depth of field of the microscopic vision system, and proposes a brand-new multi-part coplanar adjustment platform and ...
