Automatic visual inspection machine special for large automobile parts and inspection algorithm thereof

Abstract

The invention belongs to the technical field of inspection tools, and provides an automatic visual inspection machine special for large automobile parts and an inspection algorithm of the automatic visual inspection machine special for large automobile parts. The automatic visual inspection machine special for large automobile parts comprises a machine frame and a workbench arranged on the machine frame, wherein the workbench is provided with a product jig fixing device, an automatic visual inspection device, a transverse drive device and an inward and outward drive device; the automatic visual inspection device is located at the upper end of the workbench and aligns at the product jig fixing device; the transverse drive device and the inward and outward drive device drive the automatic visual inspection device to conduct transverse inspection motion and inward and outward inspection motion respectively. The automatic visual inspection machine special for large automobile parts has the advantages that the automatic visual inspection device is utilized for inspecting large automobile parts automatically, various position dimensions of products can be inspected continuously, data acquisition and CPK analysis can be carried out, and the automatic visual inspection machine is high in inspection efficiency and precision, and convenient and fast to use.

Description

technical field [0001] The invention belongs to the technical field of detection tools, and relates to a special machine for visual automatic detection of large-scale auto parts and a detection algorithm thereof. Background technique [0002] The overall shape of large-scale auto parts is relatively large (such as sunroof guide rails, etc.), and the size requirements are high. It is mainly necessary to detect the size of each hole and the size of the gap), and sometimes full inspection is required. High-end customers also need to calculate CPK (process capability index), Especially in the production of products of major customer manufacturers, the customer requires the ability to calculate the process, and the traditional detection method is very inconvenient to detect. The current detection method usually only detects the size of a fixed position, but cannot detect the size of multiple positions at the same time, or By fixing the product on the inspection tool and testing i...

[0002] The overall shape of large-scale auto parts is relatively large (such as sunroof guide rails, etc.), and the size requirements are high. It is mainly necessary to detect the size of each hole and the size of the gap), and sometimes full inspection is required. High-end customers also need to calculate CPK (process capability index), Especially in the production of products of major customer manufacturers, the customer requires the ability to calculate the process, and the traditional detection method is very inconvenient to detect. The current detection method usually only detects the size of a fixed position, but cannot detect the size of multiple positions at the same time, or By fixing the product on the inspection tool and testing it by hand, generally two people are required to test together, one person reads and one person records, the efficiency is low, the accuracy is not high, and the detection is very inconvenient. The data collection and calculation are all done manually. , and the calculation of CPK also requires a lot of follow-up work, so a tool that can not only quickly detect the key dimensions of large auto parts, but also reduce the detection methods of employees
