Heavy hole detection system of high-speed linear drilling machine

Abstract

The invention relates to a heavy hole detection system of a high-speed linear drilling machine. The system comprises the steps of 1 establishing a heavy hole sample extraction library in a server, collecting a large number of heavy hole sample photos; preprocessing the photos by using a deep convolutional neural network; extracting the position and characteristics of a heavy hole in the sample photos; recording and storing the position information and the characteristic information of the heavy hole in a sample extraction library; 2 taking a CCD camera as an acquisition end to shoot and detecta product to be detected, and uploading the shot video to a server in real time; and 3 enabling the server to compare the heavy hole characteristic information and the position characteristic information extracted in the step 1 with the video uploaded in the step 2, judge whether the detected product has a heavy hole phenomenon or not, circle out and record the position information in time when detecting similar characteristics of the heavy hole in the heavy hole sample extraction library, and give an alarm. The system has the advantages of accurate detection and high efficiency.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a heavy hole detection system of a high-speed linear drilling machine. Background technique [0002] A linear motor refers to a drive device that uses the principle of electromagnetic induction to directly convert electrical energy into kinetic energy for linear motion. It is a motor that can realize reciprocating linear motion. It has the advantages of simple structure, high positioning accuracy, fast response speed, high sensitivity and good follow-up performance. The high-speed linear drilling machine driven by a linear motor has high positioning accuracy and repeat positioning accuracy, and is more and more favored by consumers. However, in the production process, due to improper operation or high-speed linear drilling machine problems , resulting in heavy holes, that is, superimposed heavy holes, in the drilled product, you need to discard this unqualified product, but th...

The high-speed linear drilling machine driven by a linear motor has high positioning accuracy and repeat positioning accuracy, and is more and more favored by consumers. However, in the production process, due to improper operation or high-speed linear drilling machine problems , resulting in heavy holes, that is, superimposed heavy holes, in the drilled product, you need to discard this unqualified product, but there is no system for detecting heavy holes in the current products, so it is usually manually inspected with the naked eye. Firstly, the labor cost of naked eye inspection is high, and secondly, people are prone to visual fatigue, so mistakes will inevitably occur during the inspection process, resulting in inaccurate inspection
