Multi-axis linkage visual and laser combined type non-contact measurement device and measurement method

Abstract

The present invention relates to a multi-axis linked visual and laser combined type non-contact measuring device and measuring method. Non-contact detection devices on the market today confront the problems of high cost of measurement equipment, limited measurement size range and difficulty in measuring all geometric dimensions of complex workpieces. The multi-axis linked vision and laser combined type non-contact measuring device of the invention comprises a base. The multi-axis linked vision and laser combined type non-contact measuring device is characterized in that a two-axis moving platform is arranged on the base; a workpiece arrangement turntable is arranged on the two-axis moving platform; a workpiece to be tested is arranged on the workpiece arrangement turntable; the upper portion of the workpiece arrangement turntable is provided with a rising and descending mechanism; and the rising and descending mechanism is provided with a visual detection device and a non-contact distance detection device. The multi-axis linked vision and laser combined type non-contact measuring device of the invention is reasonable in structure. The visual detection device, the non-contact detection device, the rising and descending mechanism, the two-axis moving platform and the workpiece turntable platform cooperate with one another, so that the size of the workpiece to be tested can be detected quickly, automatically, accurately and reliably.

Description

technical field [0001] The invention belongs to the field of non-contact measurement of machined parts, and specifically relates to a non-contact measurement system (including a measurement device and a measurement method) that combines a multi-axis linkage precision motion mechanism with sensors such as machine vision and laser. Quality inspection of complex workpieces on the production site. Background technique [0002] With the deepening of industrial transformation and upgrading, the products produced by enterprises gradually develop from low-end to high-end, and the production changes from extensive to refined. Specifically, when it comes to the production workshop, the product inspection has changed from the original random inspection to each inspection. Enterprises A large number of on-site measuring devices are required, especially non-contact measuring devices. At present, there are a variety of non-contact detection devices for workpiece geometric dimensions comp...

Problems solved by technology

At present, there are a variety of non-contact detection devices for workpiece geometric dimensions composed of lasers and vision, such as the visual automatic measuring machine widely used in the field of magnetic materials. The measurement process is non-contact and fully automatic, with good measurement repeatability, real-time performance, and It has the characteristics of low failure rate and high precision, but there is a limited range of measurement dimensions and sensors. Most of them can only measure plane dimensions, and the measurement efficiency is low. It is difficult to measure some geometric dimensions of complex workpieces such as slots, holes and other dimensions and shape tolerances. Compared with automatic Difficult to match the production line and other issues
