Three-dimensional analysis system and method for product assembly clearance

Abstract

A three-dimensional analysis system and method for a product assembly gap is applied to a computer connected with an optical three-dimensional scanner. The product assembly gap three-dimensional analysis system and method can use an optical three-dimensional scanner to scan the product gap part between unassembled parts or the assembled product gap part to obtain the product gap point cloud, according to The scanned product gap point cloud calculates the three-dimensional space distance of the product assembly gap, uses the color tolerance zone to color-mark the product assembly parts and the surface of the assembled parts to represent the product assembly gap, and generates a three-dimensional color scale analysis of the entire product assembly gap picture.

Description

Technical field [0001] The invention relates to a product measurement system and method, in particular to a product assembly gap three-dimensional analysis system and method. Background technique [0002] Product assembly is one of the most important links in the entire production process. During product assembly, the product assembly gap between parts is an important indicator of product quality. The traditional method of measuring the product assembly gap is to use calipers or three-dimensional coordinate measuring equipment to make dots or collect corresponding point measurements at the gap of the assembled product. This traditional measurement method cannot achieve the three-dimensional measurement of the entire surface, and the measurement speed of the collection point is very slow. . Many products are now assembled using hooks, springs, glue and other screwless methods. Once assembled, they cannot be removed. If they are removed, the product will be scrapped. Summary of t...

Problems solved by technology

The traditional method of measuring the assembly gap of products is to use calipers or three-dimensional coordinate measuring equipment to measure points or collect corresponding points in the gap between assembled products. This traditional measurement method cannot achieve three-dimensional measurement of the entire shape and surface, and the measurement speed of collecting points is very slow.

Nowadays, many products are assembled without screws such as hooks, springs, and glue. Once assembled, they cannot be removed. If they are removed, the product will be scrapped.
