Problems solved by technology

The electrical box of the cylinder body is a welded structure, and there are four threaded holes distributed on each electrical box. At present, the inspection of the threaded holes on the electrical box is carried out manually. This method has a large workload and is boring, and the detection efficiency of parts is low.
However, the existing threaded hole detection equipment cannot identify the position of the threaded hole, and the thread detection device cannot be positioned independently, and cannot well adapt to the change of the threaded hole posture caused by welding deformation.

Abstract

A machine vision-based device for detecting screw holes in an electrical box of a compressor barrel includes a base assembly for supporting the device, and an execution assembly. The execution assembly is mounted on the base assembly through a three-coordinate positioning device, and the execution assembly includes a servo motor and industrial cameras, the servo motors and industrial cameras are both slidably installed on the three-coordinate positioning device through sliding connecting parts; the output end of the servo motor is connected with an end effector, and the three-coordinate positioning device and the servo motor are controlled by the PLC module. , The PLC module is connected to the computer for communication, the industrial camera is connected to the computer, the photos taken by the industrial camera are transmitted to the computer, and the computer analyzes the photo data to obtain the coordinate data of the threaded hole and feeds it back to the PLC module. The data controls the action of the three-coordinate positioning device, so that the end effector is pressed against the threaded hole. The invention improves the detection efficiency of threaded holes and reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to a detection device, in particular to a machine vision-based detection device for a screw hole of an electrical box of a compressor barrel. Background technique [0002] In the field of air-conditioning production, the threaded holes on the electrical box of the compressor barrel need to be fully inspected. The electrical box of the cylinder is a welded structure, and each electrical box is distributed with four threaded holes. At this stage, the inspection of the threaded holes on the electrical box adopts a manual method, which has a large workload and is boring, and the detection efficiency of parts is low. However, the existing threaded hole detection equipment cannot identify the threaded hole position, the thread detection device cannot be positioned autonomously, and cannot well adapt to the change of the threaded hole posture caused by welding deformation. Therefore, the development of a high-efficiency and flexible ele...
