Abstract

PURPOSE: A heating device for detecting a bonding defect in a shoe is provided to obtain an infrared thermal image using an infrared thermal image camera by heating a sample of the shoe using the heating device. CONSTITUTION: A sample is heated by using a heating device in order to obtain an infrared thermal image for detecting a defect in a bonding part of a special shoe. The heating device uniformly heats the sample in such a manner that a temperature is uniformly distributed over the whole area of the special shoe. Thus, a control section is provided to control a heating temperature of the heating device. The defect in the bonding part of the special shoe is automatically carried out by using a non-destructive process. An infrared thermal image camera is provided to detect the defect of the special shoe.

Description

신발의 접합 결함 검출을 위한 가열장치{Heating system for detect union defect of shoes}Heating system for detecting joint defects in shoes

◆발명이 속하는 기술분야◆ Technical field of invention

적외선 열화상 카메라를 이용한 특수용 신발의 접합부 결함검사를 위한 가열 장치는 비파괴 검사(NDT)의 한 분야이다.Heating devices for defect inspection of special shoes using infrared thermal imaging cameras are a field of non-destructive testing (NDT).

◆그 분야의 종래기술◆ Prior art in the field

종래기술Prior art

특수용 신발의 접합결함의 탐상 방법에서는 파괴적인 방법중의 하나인 인장 실험에 의존하고 또한 검사자의 육안에 의해서만 이루이지고 있다.The method of detecting defects in special shoes is based on the tensile test, one of the destructive methods, and only by the human eye.

종래기술의 문제점Problems of the Prior Art

기존의 방법중에서 파괴적인 방법에서는 셈플 검사로 이루어지며 파괴적인 방법을 사용하고 있기 때문에 전수검사는 이루어질 수 없는 실정이다.In the existing method, the destructive method is a sample test, and since the destructive method is used, the full test cannot be done.

전수 검사 방법으로는 검사자의 육안에 의해서 이루어지고 있는데 이 방법으로는 검사자의 주관적인 판단으로 결함을 탐상하여 그 정확성과 정량적인 방법에는 크게 미치지 못하고 있는 문제점이 있다.As a whole inspection method, it is made by the inspector's naked eye. This method has a problem of flaw detection by subjective judgment of the inspector, which is far short of its accuracy and quantitative method.

특수용 신발의 비파괴적인 방법의 접합 결함 검사에 있어서 적외선 열화상 카메라를 사용한다면 시편의 가열이 필수적이다. 이것은 열전도에 의해서 결함부분과 비 결함부분의 판별이 열전도가 다르다는 것을 이용하여 결함을 판별하는 방법이다. 따라서 가열하는 면에 고르게 열을 가하여 주어야하는 점과 열을 일정하게 전달하여야 하는 기술이 필요하다.Heating of specimens is essential if infrared thermal imaging cameras are used for nondestructive joint defect inspection of specialty footwear. This is a method of discriminating defects using the fact that the determination of the defective portion and the non-defective portion differs depending on the heat conduction. Therefore, there is a need for a point that must be heated evenly on the heating surface and a technology for transmitting heat uniformly.

도 1은 신발의 접합 결함 검출을 위한 가열장치의 전기 선도이다.1 is an electrical diagram of a heating apparatus for detecting a bonding defect of a shoe.

가열판의 일정한 온도 유지를 위한 온도 검출기와 온도 제어기, 전력조절기를 이용한다.Temperature detector, temperature controller and power controller are used to maintain a constant temperature of the heating plate.

도 2는 가열장치 제작을 위한 시편 가열부의 설계도이다. 370×150×150의 직각 사각의 외관에 내부 330×112×130의 공간을 확보하고 6개의 열선을 바닥에 깔아 신발 시편을 가열할 수 있게 설계한 도면이다.2 is a schematic view of a specimen heating unit for manufacturing a heating apparatus. It is designed to heat the shoe specimens by securing a space of 330 × 112 × 130 inside the rectangular square of 370 × 150 × 150 and laying six heating wires on the floor.

도 3은 실제 가열장치의 개발 제품이다. 시편의 일정한 온도 전달을 위하여 시편이 실제 열선 바닥으로부터 10㎜의 간격을 두었으며 두 개의 지지대를 설치하였으며 시편의 고정을 위해 나무 지그를 제작하였다. 열선 바닥의 온도를 제어하기 위하여 온도 검출기를 삽입하고 그 검출기에서 나온 온도 값을 온도 제어부에서 조절하여 전력을 조절한다.3 is a development product of the actual heating device. The specimens were spaced 10 mm from the bottom of the heating wire to provide a constant temperature transfer. Two supports were installed, and wooden jigs were fabricated to secure the specimens. To control the temperature at the bottom of the hot wire, insert a temperature detector and adjust the power by adjusting the temperature value from the detector in the temperature controller.

특수용 신발의 적외선 열화상 카메라를 이용한 접합 결함 검사에 있어서 가열장치는 일정한 온도 전달이 가능한 재질과 가열면과 가열판이 일정한 거리을 두고 공기에 의한 열전도가 가능한 구조이어야 하며 일정한 온도를 유지하기 위하여 온도 조절장치가 있어야 한다. 따라서 열판과 시편과의 일정 거리를 유지하고 균일한 열전달을 위한 가열장치와 온도 유지를 위한 온도 조절기로 구성이 되어 있다.In the inspection of bonding defects using infrared thermal imaging camera of special shoes, the heating device should be made of a material that can transmit a certain temperature and a structure that can conduct heat conduction by air with a certain distance between the heating surface and the heating plate, and to maintain a constant temperature. Should be. Therefore, it is composed of a heating device for maintaining a constant distance between the hot plate and the specimen and a temperature controller for maintaining the temperature and uniform heat transfer.

특수용 신발의 접합 결함 검사에 필요한 가열장치는 열판과 시편이 일정한 간격을 두고 가열하기 때문에 공기에 의한 균일한 온도 전달이 가능하고 사용자가 설정한 온도가 되면 자동으로 전력이 조절되어 항상 일정한 온도를 유지할 수 있어 적외선 열화상 카메라를 이용한 특수용 신발 시편의 결함 검사에 아주 용이하다.The heating device required for the inspection of defects in the joints of special shoes is heated at regular intervals so that the temperature can be transferred evenly by the air and the power is automatically adjusted when the temperature is set by the user. This makes it very easy to inspect defects in special shoe specimens using infrared thermal imaging cameras.
