AI Technical Summary

Technical Problem

In the prior art, the gear shaft string detection efficiency and accuracy in the automotive gearbox are low, and problems of misinstallation or misinstallation are prone to occur.

Method used

A detection device for misinstallation and misinstallation of shaft strings is designed, including a base, light source, projection screen, camera and processor. The projection is formed by illuminating the shaft strings by light sources. The camera collects projection images, and the processor performs image processing to detect errors. Install or missed installation.

Benefits of technology

The efficiency and accuracy of shaft string detection are improved, and a higher degree of detection automation is achieved through automated processing.

Abstract

The invention discloses a device and method for detecting misloading and neglected loading of a shaft string in the field of mechanical manufacturing, the device comprises a base, a light source, a projection curtain, a camera and a processor, the top of the base is provided with a groove for placing a central shaft of the shaft string, and the light source is used for irradiating the shaft string and forming projection on the projection curtain; the camera is used for collecting projection on the projection curtain to generate a projection image; the processor is used for acquiring the projection image and detecting misloading and neglected loading; the method comprises the steps that a light source irradiates gears of a measured shaft string on a first datum line and a second datum line in sequence to form projection on a projection curtain, and a projection image is collected through a camera; performing image processing on the projection image corresponding to each first / second reference line through a processor to obtain a corresponding projection thickness; the projection thickness is compared with the calibration thickness, and if the difference is larger than an error threshold value, misloading or neglected loading exists; according to the invention, the efficiency and accuracy of shaft string detection can be effectively improved.
