Surface defect detection system for tiny circular or circular ring-shaped parts

Abstract

The invention provides a surface defect detection system for tiny circular or circular ring-shaped parts. The system comprises a first conveying unit, a first optical detection unit, an automatic turnover unit, a first automatic separation and recovery unit, a second conveying unit, a second optical detection unit, a second automatic separation and recovery unit, a control unit and a base; a vibration damping device is adopted for completing smooth conveying and detection of the parts; and the automatic turnover unit is provided, thereby realizing automatic turnover of the parts and rearrangement for the second surface detection of the parts. The system can overcome the shortcoming that a double-head transfer mechanical hand device in a complex structure used in the prior art is difficult to control and has low detection efficiency because of difficultly in clamping the parts with characteristics of being thin and small; and a classification and recovery device for the parts with defects is adopted, thereby being conductive to statistics and analysis on the quality of the processing parts and further improving the product quality and the efficiency. The system can perform double-surface detection on the surface defects of the tiny circular or circular ring-shaped parts during the pipeline operation.

Description

technical field [0001] The invention relates to a detection system for surface defects of tiny round or ring-shaped parts, which can realize double-sided detection of surface defects of tiny round or ring-shaped parts in the process of assembly line operation. Background technique [0002] In industrial production, the detection of the surface quality of parts is an important link to ensure product quality. With the advantages of no contact, no damage, high efficiency, low false detection rate, and online real-time detection of surface defects on tiny round or circular parts, it greatly improves production efficiency and product quality. In the inspection process, how to smoothly transport parts, real-time smooth inspection, turn over and distinguish and screen defect types, and count the number has become a key technical issue. The Chinese patent application No. 200610026220.7 discloses a technical solution named "Automatic Magnetic Ring Image Detection Device". The solut...

AI Technical Summary

Problems solved by technology

The existing technical problems are: (1) The solution does not disclose how to solve the problem of how to transport parts smoothly and detect them in real time during the inspection process, and fails to disclose the rearrangement of parts detected on the second surface

(2) The structure of the double-head transfer manipulator device described in this scheme is complex and difficult to control. Because the parts are thin and small, it is not easy to clamp, so the detection efficiency of this scheme is low
