본 고안은 표면 저항 측정장치에 관한 것으로서, 특히 균일한 힘으로 동일 조건에 가장 가깝게 수회 측정하여도 그 측정치가 측정 조건변화에 관계없이 정확한 저항값을 얻을수 있도록한 표면 측정장치에 관한 것이다.The present invention relates to a surface resistance measuring apparatus, and more particularly, to a surface measuring apparatus that can obtain an accurate resistance value regardless of a change in measuring conditions even if the measurement is performed several times closest to the same condition with uniform force.

종래의 표면 측정장치는 디지털 멀티메타(저항 측정값을 디지탈로 감시해주는 기계)(1) +, -측에 침(3a)이 형성된 측정봉(3)을 연결한 표면 측정장치가 있었고, 또한 다른 측정방법으로서의 구성으로는 사각형상으로 된 동재질의 막대(4)를 분리대(5)로 일정간격을 유지시키고, 막대(4)에 디지털 멀티메타(1)의 +, -측선을 연결하여서된 표면 측정장치가 있었다.Conventional surface measuring device has a digital measuring device (digital monitoring the resistance measurement value) (1) +,-the surface measuring device connected to the measuring rod (3) formed with a needle (3a) on the-side, and also In the configuration as a measuring method, a rectangular bar of the same material (4) is maintained at a constant interval with the separator (5), and the surface of the bar by connecting the +,-side of the digital multimeter (1) There was a measuring device.

상기의 구성을 표면 저항 측정장치중에 전자의 측정장치는 측정봉(3)의 침(3a)를 몰체(2)의 실드로료층(2a)에 일정거리(A)를 두고 찍어보다 디지털 멀티 메타(1)에 표시되는 수치를 측정값으로 읽었다.In the above-described surface resistance measuring apparatus, the former measuring apparatus photographs the needle 3a of the measuring rod 3 with a certain distance A on the shield material layer 2a of the molten body 2, and the digital multi-meta ( The numerical value displayed in 1) was read as a measured value.

그러나 이 측정장치는 침(3a)의 선단이 뾰족하고 일정거리(A)의 균일성이 없으므로 이를 보완하기 위하여 후자의 측정장치를 안출하였는데 사각형 상의 막대(4)를 일정치수(C)(D)폭으로 만들었고, 막대(4)의 측정간격(B)을 매번 유지하기 위해서 B간격을 갖는 분리대(5)를 막대 사이에 설치해서 제2도와 같이 물체(2)의 표면에 대고 제1도의 디지털 멀티메타(1)에서 지시하는 값을 저항값으로 읽었던 것이다.However, this measuring device has a sharp tip and uniformity of a certain distance (A). Therefore, the latter measuring device was designed to compensate for this. In order to maintain the measurement interval B of the rod 4 each time, a separator 5 having a B interval is installed between the rods and placed on the surface of the object 2 as shown in FIG. The value indicated by the meta (1) was read as the resistance value.

따라서 전자의 경우는 매번 측정시마다. +, -극간 A간격을 동일하게 유지하기가 힘들고 일정거릴 유지를 위해 시간을 허비해야되는 문제점이 있었고, 후자의 경우에는 극간 간격 B를 유지하기는 용이하다. 막대의 표면이 평면이므로 다소 굴곡진 부위의 측정시 접촉저항이 발생하여 저항값의 신뢰를 떨어뜨리게 되었으며 일정간격의 유지는 외나 측장자가 누르는 힘의 차이에서 저항값이 크게 틀려지는 사실이 가장 큰 문제점으로 대두되었던 것이다.Therefore, in the former case every measurement. There was a problem that it was difficult to maintain the same A interval between + and-poles and wasted time to maintain a constant distance. In the latter case, it was easy to maintain the interval B between poles. Since the surface of the bar is flat, contact resistance is generated when measuring a somewhat curved area, which lowers the reliability of the resistance value. It was a problem.

이러한 문제점들을 해결하기 위해 안출한 본 고안은 일정간격의 유지 및 동일한 힘으로 측정이 가능함과 굴곡진 곳에서도 용이한 측정을 할수 있게한 것으로 이를 첨부도면과 함께 상세히 다음과 같다.The present invention devised to solve these problems can be measured at a constant interval and the same force and easy to measure even in a bent position with the accompanying drawings in detail as follows.

제3도는 본 고안에 대한 측정기의 사시도인 것으로 지지역활을 하는 평판(7)의 같은 거리(E=F)가 되는 4곳에 각각의 구멍을 뚫어 평판의 저면에서 가이드관(11)을 삽입하되 가이드관의 턱(11c)이 평판에 걸려 더 이상의 전진을 하지 못할 때 고정시킨다.3 is a perspective view of the measuring device according to the present invention, and the guide pipe 11 is inserted into the bottom of the plate by drilling holes in each of four places that are equal distances (E = F) of the plate 7 performing the local area. It is fixed when the jaw 11c of the tube hangs on the plate and no further advancement is possible.

상기의 고정상태에서 가이드관(11)의 상면에 디지털 멀티메타(1)의 +, -측선(15)(16)을 연결하고, 가이드관(11)의 저면으로는 압축스프링(14)과 함께 정지턱(8b)이 형성된 주축봉(8)을 삽입한다.In the above fixed state, the + and-side lines 15 and 16 of the digital multimeter 1 are connected to the upper surface of the guide tube 11, and the compression spring 14 is connected to the bottom of the guide tube 11. Insert the main shaft bar (8) formed with the stop jaw (8b).

제4도는 본 고안에 대한 측정기의 조립사태 단면도인 것으로 가이드관(11)에 주축봉(8)을 삽입하는 구성을 자세히 설명하면 가이드관(11)의 내경(11b)의 입구(11a)에 나사산(12)을 형성하고 주축봉(8)의 선단에는 나사부(13)를 형성한다.Figure 4 is a cross-sectional view of the assembly state of the measuring device according to the present invention to explain in detail the configuration of inserting the spindle shaft 8 in the guide tube 11, the thread to the inlet (11a) of the inner diameter (11b) of the guide tube (11) (12) is formed, and the threaded portion (13) is formed at the tip of the main shaft bar (8).

상기의 주축봉(8)의 나사부(13) 선단에느 압축스프링(14)을 용법으로 고정하여 이를 가이드관(11)의 내경(11b)으로 끼울때에 나사부(13)와 나사산(12)을통과하여 가이드관(11)의 내경(11b)에 위치하도록 조립한 다음 압축스프링(14)의 선단을 가이드관(11)의 선단에 납땜으로 고정하여, +, -측선(15)(16)과 연결되게 하여 형성한다.When the compression spring 14 is fixed to the tip of the screw portion 13 of the main shaft rod 8 by means of use, the screw portion 13 and the thread 12 are screwed into the inner diameter 11b of the guide tube 11. Assembled so as to be located in the inner diameter (11b) of the guide tube 11, and then fixed the end of the compression spring (14) by soldering to the end of the guide tube (11), the +,-side line (15) (16) and Form to be connected.

그리고 가이드관(11)의 입구(11a)에는 절연 부싱(19)을 끼워 고정하고, 주축봉(8)에는 눌려지는 거리에 정지턱(8b)을 고정하고 선단에는 접촉봉(8a)을 설치한다.The inlet 11a of the guide tube 11 is fitted with an insulating bushing 19 to fix the stop jaw 8b at a distance pressed against the spindle rod 8, and a contact bar 8a is installed at the tip. .

이러한 구성으로 이루어진 본 고안의 평판(7)에 덮개(17)를 씌워서, 표면저항 측정장치를 형성한 다음 이를 평판(7)상에 올려놓고 누르면 외부압력에 의해 주축봉(8)의 압축스프링(14)을 누르면서 기이드관(11)으로 들어오게 되고 정지턱(8b)이 가이드관의 절연부싱( 19)에 접촉할 때 누름작업을 정지하여 이때 디지털 멀티메탈(1)에 나타난 치수가 저항치를 나타낸다.By covering the cover 17 on the flat plate 7 of the present invention having such a configuration, and forming a surface resistance measuring device and then placing it on the flat plate 7 and pressing the compression spring of the spindle bar 8 by the external pressure ( 14) While pressing down, it enters the guide tube 11 and stops the pressing operation when the stop jaw 8b contacts the insulating bushing 19 of the guide tube. At this time, the dimension shown in the digital multimetal 1 shows the resistance value. Indicates.

누르던 평판(7)에서 힘을 제거하여 압축된 스프링(14)의 반발력으로 주측봉(8)은 최초의 위치로 튀어나오게 된다. 이러한 방법으로 표면 저항치를 측정하는 본 고안은 주축봉(8)의 단면적이 작기 때문에 표면에 약간의 굴곡, 구멍, 리브 등이 있어서 측정에 제한을 받지 않는다.The repelling force of the compressed spring 14 by removing the force from the pressed flat plate 7 causes the main rod 8 to protrude to its initial position. In the present invention for measuring the surface resistance in this way, since the cross-sectional area of the spindle 6 is small, there are some bends, holes, ribs, etc. on the surface, so that the measurement is not limited.

그리고 본 고안의 측정장치는 외부에서 힘을 더해 주축봉이 정지할때에 나타난 표시값을 읽기 때문에 각 측정자가 정지턱이 닿은때까지만 누른다면 매번 정확한 힘으로 눌러 줄수 있고 그에 대한 저항치가 동일하여 누르는 시험자에 의한 측정오차를 피할수 있다.In addition, the measuring device of the present invention reads the display value displayed when the spindle is stopped by adding force from the outside, so that each tester can press it with the correct force every time until the stopping jaw touches it, and the tester presses the same resistance against it. Measurement error caused by

또 측정과정에서 정지턱은 가이드관의 절연붓싱에 닿기 때문에 접촉저항을 없앨수 없고, +, -선의 연결상태의 변화에 따라 좁은 부위의 측정도 가능한 것이다.In addition, the stopping jaw touches the insulation bushing of the guide tube, so that the contact resistance cannot be eliminated, and the narrow part can be measured according to the change in the connection state of the + and-wires.

이상에서와 같이 본 고안은 주측봉에 일정한 거리를 유지시키면서 탄력성을 이용 균일한 힘에 의한 정확한 저항치의 측정이 가능한 효과가 있으며 측정면의 상태에 구애받지 않고 선의 연결상태만 2점지지 방식으로 변형시키면 측정범위를 좁은곳까지 확장시킬수 있는 이점이 있어서 정확한 측정기능을 수행할수 있는 제품의 품질을 향상시킬수 있는 것이다.As described above, the present invention has the effect that it is possible to measure the exact resistance value by the uniform force by using the elasticity while maintaining a constant distance to the main bar, and deformed by the two-point supporting method only the connected state of the wire regardless of the state of the measuring surface. This has the advantage that the measuring range can be extended to a narrow area, thereby improving the quality of the product that can perform the accurate measuring function.
