Embodiment Construction

[0045] In order to make the above objects, features, and advantages of the present invention, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other fails there are many otherwise described herein, and those skilled in the art can be similarly improved without departing from the connotation of the present invention, and thus the present invention is not limited by the specific embodiments disclosed below.

[0046] It should be noted that when the element is referred to as "fixed to" another element, it can be directly in another element or may also exist. When a component is considered to be "connected" another element, it may be directly connected to another element or may always exist in the center element. The term "vertical", "horizont...

Abstract

The invention discloses an electrode cap surface defect detection device based on machine vision, and relates to the technical field of electrode cap surface defect detection. The top light source is integrally mounted at the top of the shell and is used for vertically lighting downwards and lighting an optical fiber on the plane mirror, and then the optical fiber is reflected to the side surface of the electrode cap by the plane mirror for the first time and is reflected to the cap end of the electrode cap by the two groups of triangular prism plane mirrors for the second time, so that a sample piece is illuminated by the light source; the side light source is fixed on the side surface of the shell, and the integrated camera is powered by a USB line and transmits acquired data; and the integrated camera is arranged at the lower end of the top light source and is used for carrying out image acquisition on the electrode cap. The device is small in occupied space, is designed on the premise that the field operation environment and the operation efficiency are not affected, and meets the detection standard. The electrode cap surface defect detection device is a closed environment, has low requirements on complex light and shade of a light source on site and a dust pollution environment, and has relatively high brightness interference resistance and dust interference resistance.

Description

Technical field [0001] The present invention discloses to the field of electrode cap surface defect detection techniques, and more particularly to a machine-visual electrode cap surface defect detecting device. Background technique [0002] The electrode cap belongs to a weld electrode, for the welding of the resistance welding equipment, such as a fixed point welder, a suspension-based welder, and a robotic welder, such as the sleeve, so that the electrode cap is referred to as a electrode cap. Most of the material is chromium zirconium, and there is also a dispersion. After the soldering is a certain number of times (generally 1000-1200 points), it is necessary to wear or replace due to wear, which belongs to the welding consumables. [0003] The electrode cap will produce two defects during processing, and the top of the electrode cap is oxidized, the surface will be black, affecting its conductivity; the second is the wear of the tail end, wear the annular dimple position, th...
