Embodiment Construction

[0045] The present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0046] Such as figure 1 As shown, the present invention provides a method for superimposing and fusing the contact surface components of an electromagnetic relay, comprising the following steps:

[0047] 1) Select a contact of the electromagnetic relay to scan a single element respectively;

[0048] 2) Sorting out the morphology of contacts containing C, O, Ag, and Mg elements alone, and establishing a single-element microscopic morphology feature point recognition model;

[0049] 3) Establish a multi-element contact shape superposition model containing C, O, Ag, and Mg elements, and perform microscopic shape feature point matching;

[0050] 4) Construct a transformation model to complete the superposition and fusion of multiple components of the contact.

[0051] In step 1), arrange the contact surface microscopic appearance (such as figure 2 ...

Abstract

The invention discloses a method for superimposing and fusing contact surface components of an electromagnetic relay, which comprises the following steps: 1) selecting a contact of an electromagnetic relay to scan a single element; 3) Establish a multi-element contact shape superposition model containing C, O, Ag and Mg elements to match the microscopic shape feature points; 4) Build a transformation model , to complete the superposition and fusion of the multiple components of the contact. Based on the research on the superposition and fusion method of the contact surface components of the electromagnetic relay, the present invention proposes a microcosmic feature point recognition model of each component on the contact surface of the relay, calculates the transformation parameter matrix, and completes the superposition and fusion of the contact surface components of different elements, which can A more scientific and comprehensive characterization of the comprehensive element distribution on the surface of relay contacts.

Description

technical field [0001] The invention relates to a component analysis technology of an electromagnetic relay contact, in particular to a method for superimposing and fusing components of the contact surface of an electromagnetic relay. Background technique [0002] The core component of the relay is the contact, and the change of the surface composition of the contact directly affects the life and reliability of the relay. In order to ensure accurate evaluation of the use status of the relay, it is necessary to study the surface morphology of the relay contacts. Many scholars at home and abroad reflect the shape change of the contact through the roughness of the contact surface, but they cannot directly reflect the change of the contact surface, which brings great difficulties to the reliability and life evaluation of the relay. [0003] The current evaluation of the relay contact surface is mainly based on the quality change of the contact surface or the change of the conta...
