AI Technical Summary

Technical Problem

Traditional detection methods have low accuracy in confined spaces, which cannot meet the needs of intelligent equipment development. They also have large measurement errors, are cumbersome to operate, and pose safety hazards.

Method used

A posture adjustment device is adopted, including a detection housing, a camera, a coaxial light source and a control system. It automatically detects the symmetry between the loading and unloading device and the magazine in a non-contact manner. It uses a laser displacement sensor to measure the tray height and combines camera image processing to calculate the center coordinates to achieve high-precision symmetry detection.

Benefits of technology

It improves the accuracy and efficiency of detection, enhances operational safety and stability, and meets the needs of intelligent equipment.

Abstract

This application provides a posture adjustment device, method, and apparatus for use in confined spaces within an ammunition feeder. When the need to detect the central symmetry of the ammunition feeder is determined, the posture adjustment device controls a pickup / delivery device to move the posture adjustment device itself, which is mounted on the pickup / delivery device, towards a designated position in the direction of a first magazine tray (the target magazine tray). A camera is then controlled to photograph the target magazine tray, and the center coordinates are determined based on the image. The pickup / delivery device is then controlled to move towards a designated position in the direction of a second magazine tray, and the process returns to the step of controlling the camera to photograph the target magazine tray again to determine the center coordinates. If the target distance difference between the calculated first distance difference and the second distance difference is not within the distance error range, the position of the ammunition feeder is adjusted according to the distance difference, and the process returns to the step of controlling the pickup / delivery device to move towards the designated position in the direction of the target magazine tray, until the distance error is within the range. Therefore, this application improves operational safety, measurement accuracy, and efficiency.
