Description

사출물의 하드웨어 검사장치{hardware detecting device for insert injection}Hardware detecting device for insert injection

본 발명은 사출물에 하드웨어의 삽입 여부를 검사하는 장치에 관한 것으로, 더욱 상세하게는 품질 검사시, 다양한 형상의 사출물에 하드웨어 삽입 유무를 빠르고 정확하게 검사가 이루어짐으로써, 사출물에 부품들을 조립시 제품의 생산성은 향상되고, 제품의 불량률은 감소하는 사출물의 하드웨어 검사장치에 관한 것이다.The present invention relates to an apparatus for inspecting whether or not the hardware is inserted into the injection molding, and more particularly, in the quality inspection, by quickly and accurately inspecting whether the hardware is inserted into the injection molding of various shapes, the productivity of the product when assembling the parts in the injection molding Is improved, and the defective rate of the product is related to the hardware inspection device of the injection molding.

일반적으로 엔지니어링 플라스틱의 경우 일반 플라스틱에 비하여 개선강도 및 물성으로 인해 사출 공정을 통해 다양하게 작용이 되고 있다. 특히 모터/인버터 단자대 및 커넥팅 하우징 등을 특정 위치에 고정하기 위해서는 사출물의 고정부에 철계의 너트나 부시(이하, 하드웨어 라 칭한다) 등의 금속부품을 일체화하여 사출하여야 한다. 이를 인서트 사출이라고 한다.In general, engineering plastics have a variety of functions through the injection process due to improved strength and physical properties compared to ordinary plastics. In particular, in order to fix the motor / inverter terminal block and the connecting housing to a specific position, the metal parts such as iron nuts or bushes (hereinafter referred to as hardware) should be integrally injected into the fixing part of the injection molded product. This is called insert injection.

상기 인서트 사출은 사출공정 내에서 하드웨어와 플라스틱이 금형을 통해 한번에 이루어진다.The insert injection is performed at once through hardware and plastic through a mold in the injection process.

그러므로 인서트 사출물에 삽입된 하드웨어 등은 크기가 작고 대부분 사출공정 중에 작업자에 수작업에 의해 금형에 조립되는 경우가 많아서 최종 사출물을 출하 전에 제대로 인서트 사출이 이루어졌는지 품질 검사가 반드시 필요하다.Therefore, the hardware and the like inserted into the insert injection molding are small in size and are often assembled in the mold by manual operation by the operator during the injection process. Therefore, it is necessary to check the quality of the insert injection before the final injection is shipped.

그러나 종래의 품질 검사는 사출물에 하드웨어의 삽입 여부를 검사자의 육안에 의존해 왔다. 이는 다양한 형상으로 제작되는 사출물의 특성상 표준화된 검사용 치구를 만들기 어렵고, 각각의 검사용 치구를 만들 경우에는 추가 비용이 발생하는 문제점이 있었다.However, conventional quality inspections have depended on the naked eye of the inspector whether the hardware is inserted into the injection molding. This is difficult to make a standardized test jig due to the nature of the injection molding is produced in a variety of shapes, there was a problem that additional costs occur when each test jig made.

또, 육안검사시 검사자의 심리상태에 따라 하드웨어 삽입 유무에 대한 엄밀한 검사하는 것이 어렵고, 사출물에 하드웨어 적용 개소가 증가하거나 외부에서 육안 검사가 어려운 형상일 경우에는 검사 자체가 불가능해질 수 있는 문제점이 있었다.In addition, it is difficult to strictly inspect the presence or absence of hardware insertion depending on the psychological state of the inspector during visual inspection, and the inspection itself may be impossible if the hardware application point is increased or the shape is difficult to visually inspect from the outside. .

또한, 사출물에 불량이 확인되지 않은 상항에서 사출물에 순차적 공정을 통해 부품들을 조립할 경우, 조립공정 중에 사출물에 불량여부가 판별되면 부품들을 재조립하여야 하기 때문에 조립이 지연에 따라 제품의 생산성이 저하되는 문제점이 있었다.
In addition, when assembling the parts through the sequential process in the injection molding when the defect is not confirmed in the injection molding, if the defect is determined in the injection molding during the assembly process, because the parts must be reassembled, the productivity of the product decreases as the assembly is delayed. There was a problem.

이에 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 검사자에 의한 육안 검사에 의존하지 않고 장치를 통해 사출물에 하드웨어 삽입 유무를 검사할 수 있도록 함으로써, Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to enable the inspection of the presence of hardware in the injection through the device without relying on visual inspection by the inspector,

다양한 형상의 사출물의 품질 검사도 용이하게 이루어질 수 있도록 하고, 정확한 품질 검사로 사출물에 부품들을 조립하기 전에 불량 사출물이 제거되어 부품들의 재조립에 따른 제품의 생산성이 저하되지 않도록 하는 것을 제공하는 것이다.

상기와 같이 구성된 본 발명의 작용 상태를 설명하면 다음과 같다.The operation state of the present invention having the above-described structure will now be described.

도 4 내지, 도 6에 도시된 바와 같이 사출물(200)에 하드웨어(210) 삽입 유무를 검사하기 위해, 검사자가 하드웨어 검사장치(100)를 사출물(200)에 근접시키면, 영구자석(110)에 발생한 자기장의 흐름은 변하게 된다.4 to 6, in order to inspect whether the hardware 210 is inserted into the injection molding 200, when the inspector approaches the hardware inspection apparatus 100 to the injection molding 200, the permanent magnet 110 The flow of the generated magnetic field changes.

이를 구체적으로 설명하면, 상기 하드웨어 검사장치(100)가 평상시에는 도 5에 도시된 바와 같이 영구자석(110)에 의해 발생한 자기장의 흐름은 영구자석(110)에서 출발하여 요크부(120)로 돌아오게 된다.Specifically, the hardware inspection apparatus 100 normally flows the magnetic field generated by the permanent magnet 110 as shown in FIG. 5 to the yoke unit 120 starting from the permanent magnet 110. Come.

하지만, 하드웨어 검사장치(100)가 사출물에 근접하면, 도 6에 도시된 바와 같이 영구자석(110)에 의해 발생한 자기장의 흐름은 영구자석(110)에서 출발하여 사출물(200)의 내부에 삽입된 하드웨어(210)를 거친 다음, 요크부(120)로 돌아오게 된다.However, when the hardware inspection device 100 is close to the injection molding, as shown in FIG. 6, the flow of the magnetic field generated by the permanent magnet 110 starts from the permanent magnet 110 and is inserted into the injection molding 200. After going through the hardware 210, it is returned to the yoke portion 120.

이는 영구자석(110)과 하드웨어(210) 사이에 자기력이 형성되어 자기장의 흐름이 바뀌면서 자속밀도 또한 함께 변하게 되는 것이다.The magnetic force is formed between the permanent magnet 110 and the hardware 210, the magnetic flux density is also changed as the flow of the magnetic field is changed.

따라서, 상기 전압측정기(300)에 연결라인(310)에 의해 전기적으로 연결된 감지부(130)는 자속밀도 차이를 전압차로 변환하고 이를 상기 전압측정기(300)에 전송하게 된다.Therefore, the sensing unit 130 electrically connected to the voltage meter 300 by the connection line 310 converts the magnetic flux density difference into a voltage difference and transmits it to the voltage meter 300.

그리고 상기 전압측정기(300)는 하드웨어 검사장치(100)가 사출물(200)에 근접하기 전과, 후에 전압수치 변화를 검사자가 인식할 수 있도록 디스플레이하게 된다. In addition, the voltage measuring device 300 displays the change of the voltage value before and after the hardware inspection device 100 approaches the injection molding 200 so that the inspector can recognize the change.

이때, 전압측정기(300)에서 디스플레이되는 전압수치가 변하면, 사출물(200)에 하드웨어(210)가 삽입되었다는 것을 의미하며, 전압수치가 변하지 않으면 사출물(200)에 하드웨어(210)가 삽입되어 있지 않다는 것을 의미하게 된다. In this case, when the voltage value displayed by the voltage meter 300 is changed, it means that the hardware 210 is inserted into the injection molding 200. If the voltage value does not change, the hardware 210 is not inserted into the injection molding 200. Will mean.

그러므로 검수자는 전압측청기를 통해 측정치의 변화를 보고 사출물에 하드웨어 삽입 유무를 검사할 수 있다.
Therefore, the inspector can check the measured value through the voltage probe and check the presence of hardware in the injection molding.
