System for non-destructively inspecting and determining sealing of aluminum pouch by using ultrasonic waves

Abstract

The invention relates to a system for non-destructively inspecting and determining sealing of an aluminum pouch by using ultrasonic waves, the system comprising: an ultrasonic wave generation unit comprising probes which generate ultrasonic waves, and transmit and receive the ultrasonic signals to and from an object of a non-destructive inspection, placed on an inspection table; an interface unitfor transmitting an ultrasonic signal, received from the ultrasonic wave generation unit, to an ultrasonic wave generation data control unit; the ultrasonic wave generation data control unit for processing the ultrasonic data received from the interface unit; a sealing defect determination unit for determining whether sealing is defective, on the basis of the processed ultrasonic data; and a display unit for displaying the determination result on a monitor. The invention uses a transmittance of an ultrasonic wave to implement a color-marked area such that a dense area (sealing part) of a transmissive part having a high transmittance is marked in red and a low-dense area (air part) of a transmissive part having a low transmittance is marked in blue, and thus makes it possible to detect andcheck an unsealed part of an aluminum pouch through a non-destructive inspection.

Description

technical field [0001] The present invention relates to a non-destructive testing judgment system about the sealing of an aluminum bag using ultrasonic waves, in which a region having a high density at a transmissive portion having a high transmittance is displayed in red using the transmittance of ultrasonic waves (sealed portion), and a region with low density (air portion) at the transmissive portion with low transmittance is shown in blue, so that the unsealed portion of the aluminum pouch (pouch) can be detected and checked by non-destructive testing, which The nondestructive testing judging system includes: an ultrasonic generation data controller, which includes processing software for detecting an unsealed part of a sealed part of an aluminum bag through nondestructive testing using ultrasonic waves, along with measurable sealing The length of the width, setting the judgment reference value, processing the measurement data, and performing automatic judgment; a seal def...

Problems solved by technology

Furthermore, it is a problem that the high output ultrasonic waves at the tip of the tool horns currently used can cause surface damage on the contact surface of the test body

[0014] In addition, in the design of the metal tool horn, the length of the tool horn should be designed to be physically 1 / 2 the wavelength of the oscillating ultrasonic waves, and there is a problem that such a design leads to an increase in the size of the ultrasonic excitation equipment

[0015] Conventionally, although it is possible to detect the unsealed portion and measure the length of the sealing width by non-destructive testing on the sealing portion of the aluminum bag, the problem is that since there is no software for processing the measurement data, the judgment must be made by the measurer. After checking all the data directly
