Embodiment Construction

[0020] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0021] The method for detecting the glue application state of the present invention judges the glue application state on the ultrasonic probe by means of image analysis. When the thickness of the glue is insufficient or the coupling degree of the glue is not good, etc., the scanned image will be unclear or distorted. Therefore, if the state of gluing can be automatically detected, the probability of scanning errors can be reduced and the clarity of the image can be improved. Therefore, the present invention judges the thickness, coupling degree and uniformity of the glue on the ultrasonic probe by detecting the ultrasonic image. The signal of the thickness, coupling degree or uniformity not reaching the standard value is displayed on the display, or as a reference fo...

Abstract

The invention provides a method for detecting a gluing state of an ultrasonic probe. The method comprises the following steps of coating a glue layer on an ultrasonic probe, carrying out image scanning to obtain a corresponding scan image, dividing the scan image into a strong reflecting region and a weak reflection region, and detecting a signal change of the scan image in the strong reflecting region thereby determining a gluing state. The method can effectively avoid scan image blur or distortion caused by deficiency of glue thickness or a poor coupling degree of gluing and can improve ultrasonic detection performances.

Description

technical field [0001] The invention relates to a detection method, and in particular to a method for detecting the state of glue coating on an ultrasonic probe. Background technique [0002] In non-destructive testing, ultrasonic scanners are often used to emit ultrasonic waves and receive echo signals generated by reflecting the ultrasonic waves for detection. There is a precise ultrasonic array element in the ultrasonic probe to detect the strength of the scanning signal, but the performance of the ultrasonic array element will be gradually lost due to the use of the situation and the increase of time, so the parameters must be adjusted to meet the requirements of ultrasonic detection . When the ultrasonic scanner is scanning, the coupling gel is mainly used as the coupling medium between the probe and the detection object to reduce the energy loss caused by the contact between the ultrasonic wave and the air. However, when the thickness of the glue is insufficient or t...
