Abstract

The invention discloses assembly measuring device and method of tiny parts in a narrow space based on an industrial fiberscope, used for the on line measurement on tiny parts in a narrow space. The assembly measuring device comprises a fiberscope detection device, a precise linear motion platform and a computer, wherein the fiberscope detection device acquires assembled image information and transmits the assembled image information to the computer; the precise linear motion platform is used for moving the fiberscope detection device; and the motion information of a precise linear guide rail is controlled by computer programming. In the measuring method, the fiberscope carries out measurement on two different positions in the measuring direction, and then the computer processes and computes by combining with image information measured twice with motion position information, thereby measuring the information for assembling the tiny parts. By adopting the industrial fiberscope and a light source interface thereof, the invention realizes the integrated illumination observation in the narrow space. The information on the motion trail of the fiberscope can be precisely obtained in real time by adopting the precise motion guide rail additionally provided with a linear scale to drive the fiberscope to move.

Description

technical field

[0001] The invention relates to a device and method for assembling and measuring tiny parts in a narrow space based on an industrial endoscope, which belongs to the technical field of micro assembling and is used for on-line measurement of assembling tiny parts in a narrow space. Background technique

[0002] Micro-assembly is a technology that assembles multiple micro-parts into complex micro-systems through accurate manipulation and positioning. At present, most micro-assembly work is still done manually by operators. Building an automated micro-assembly system will improve assembly accuracy, assembly efficiency and product stability, and at the same time free operators from boring and tedious micro-work, reducing the influence of human factors.

[0003] A key step in automated assembly is to check out assembly information in real time, quickly and accurately. Usually machine vision methods are used. In the detection of thin parts, the SP214202K30 line sc...
