Spherical fuel element automatic appearance detection device

Abstract

The invention relates to a spherical fuel element automatic appearance detection device. The spherical fuel element automatic appearance detection device comprises a feed mechanism, a primary inspection station, a conveying mechanism, a secondary inspection station, and a sorting mechanism which are connected successively; a workpiece to be measured is pushed to the primary inspection station by the feed mechanism, and detection on defects with large area and low depth is carried out; the workpiece is pushed to the secondary inspection station by the conveying mechanism, and detection on defects with small area and high depth is carried out; after detection, unqualified elements are rejected by the sorting mechanism, and are introduced into an unqualified sphere storage container, and qualified spheres are introduced into a qualified sphere discharging machine. The spherical fuel element automatic appearance detection device is capable of solving a problem in the prior art that detection results are easily influenced by uncertain factors such as the technical level, the responsibility, and the fatigue degree of workers, reducing false detection and miss rate greatly, increasing automation degree greatly, reducing the number of visual detection staff, and reducing enterprise artificial cost and management cost effectively.

Description

technical field [0001] The invention belongs to the field of appearance inspection of spherical fuel elements, and in particular relates to an automatic appearance inspection device for spherical fuel elements. Background technique [0002] At present, the technologies used for visual defect detection include: eddy current flaw detection method, ultrasonic flaw detection method, photoelectric detection method, acoustic emission method, and manual detection method. The eddy current flaw detection method uses the principle of electromagnetic induction to detect defects. The inspected product will generate eddy current under the action of alternating magnetic field. The surface defect of the product affects the size and distribution of the eddy current. The eddy current distribution of the defective product and the normal product can be judged according to the change of the eddy current received by the sensor. exist. This method has a high sorting ability for visual processin...

AI Technical Summary

Problems solved by technology

This method is easily affected by unstable factors such as workers' technical level, emotion, sense of responsibility, and fatigue, so the rate of false detection and missed detection is high, and the degree of automation is low, which increases labor costs and management costs for the company.

In addition, many inspection procedures not only require the inspection of the appearance, but also need to accurately obtain the statistical data of the inspection, such as the type and size of the surface defect of the spherical fuel element, etc. These tasks are difficult to be completed quickly by human eyes
