Abstract
Description
しかし、上記従来のテープ電線の整形装置では、窓部に対する補強板の位置関係を検査できない問題点があった。すなわち、カメラの側から照明を補強板付きフラットケーブルに当てて反射画像を検出した場合は、裏面に貼り付けてある補強板を検査できない。一方、カメラと反対の側から照明を補強板付きフラットケーブルに当てて透過画像を検出する場合は、補強板の影から補強板を検査できても、照明光がエッジに回り込んで透過画像上にエッジが適正に現れず、マージンを適正に検査できなくなる。また、照明光がエッジから回り込まない程度の弱い光強度の照明光の場合は、透過率が高く差異があまり無い部材、例えば絶縁体である基材と補強板を積層した補強板付きフラットケーブル、では、透過画像に前記基材と補強板の明らかな濃淡差のある影ができず、窓部に対する補強版の位置(以下、補強板位置)を検査できない。
なお、補強板付きフラットケーブルの両側にそれぞれカメラと照明のセットを設けて補強板付きフラットケーブルの両面の反射画像を検出すれば、補強板付きフラットケーブルのマージン及び補強板位置の両方を検査できるが、2セットのカメラと照明および2つの画像解析装置が必要になり、構成が複雑になってしまう。
そこで、本発明の目的は、1セットのカメラと照明および1つの画像解析装置により、補強板付きフラットケーブルの表面構造検査、例えばマージン及び補強板位置の検査、を行うことが出来ると共に、補強板付きフラットケーブル以外の例えばフレキシブル回路基板のような積層体の透過画像を用いた内部構造検査、例えば導体のピッチや幅・補強板位置等の寸法(以下、寸法)やキズ・へこみ・断線等の欠陥(以下、欠陥)の検査、を行うことが出来る積層体の検査方法および積層体検査装置、並びに、その積層体検査装置を利用することによってインラインで品質を管理しながら積層体を製造することが出来る積層体製造装置を提供することにある。 In a flat cable with a reinforcing plate, there is a demand to check not only the margin but also the suitability of the position where the reinforcing plate is attached to the window portion.
However, the conventional tape electric wire shaping apparatus has a problem that the positional relationship of the reinforcing plate with respect to the window portion cannot be inspected. That is, when a reflected image is detected by illuminating a flat cable with a reinforcing plate from the camera side, the reinforcing plate attached to the back surface cannot be inspected. On the other hand, when detecting the transmitted image by illuminating the flat cable with the reinforcing plate from the side opposite to the camera, the illumination light wraps around the edge even if the reinforcing plate can be inspected from the shadow of the reinforcing plate. Therefore, the edge does not appear properly and the margin cannot be properly inspected. In addition, in the case of illumination light with weak light intensity that does not illuminate from the edge, a member with a high transmittance and a difference that is not so different, for example, a flat cable with a reinforcing plate in which a base material that is an insulator and a reinforcing plate are laminated, In the transmission image, a shadow having a clear contrast between the base material and the reinforcing plate cannot be formed on the transmission image, and the position of the reinforcing plate relative to the window (hereinafter referred to as the reinforcing plate position) cannot be inspected.
In addition, if a camera and a lighting set are provided on both sides of the flat cable with the reinforcing plate and the reflection images on both sides of the flat cable with the reinforcing plate are detected, both the margin of the flat cable with the reinforcing plate and the position of the reinforcing plate can be inspected. However, two sets of cameras, illumination, and two image analysis devices are required, and the configuration becomes complicated.
Accordingly, an object of the present invention is to perform a surface structure inspection of a flat cable with a reinforcing plate, for example, an inspection of a margin and a reinforcing plate position, with a set of camera, illumination, and one image analysis device. Internal structure inspection using transmission images of laminates such as flexible circuit boards other than flat cables, such as conductor pitch, width, reinforcement plate position, etc. (hereinafter referred to as dimensions), scratches, dents, disconnections, etc. Laminate inspection method and laminate inspection apparatus capable of inspecting defects (hereinafter referred to as defects) and laminate inspection apparatus, and manufacturing laminates while controlling quality in-line by using the laminate inspection apparatus It is in providing the laminated body manufacturing apparatus which can do.
上記第1の観点による積層体の検査方法では、第1の光強度を、例えば補強板付きフラットケーブル(C)の第1面側から光を当てたときに、第2面側へ、不透過部材(c1)あるいは半透過部材(c1)あるいは透過部材(c5)の影を作りうる光強度とする。これにより、不透過部材(c1)あるいは半透過部材(c1)および透過部材(c5)の位置を検査できる。ただし、第1の光強度では、光がエッジ部で回り込んで画像上にエッジが適正に現れず、マージンを適正に検査することは出来ない。そこで、第2の光強度は、光がエッジ部で回り込んで画像上にエッジが適正に現れなくなる現象を抑制できるように、第1の光強度よりも弱くする。これにより、補強板付きフラットケーブル(C)の第2面側へエッジ(cE)の影を適正に作ることが出来るので、マージンも適正に検査することが出来る。
照明としては、積層体(C)の内部構造や表面構造を検査する対象を第1の光強度で照射し、エッジを第1の光強度より弱い第2の光強度で照射することで、エッジの位置を正確に測定できるようにする。
具体的には,上記照明手段を用いて第1の光強度の光を照射することで、不透過部材あるいは半透過部材(c1)または透過部材(c5)の透過率の差異や重なり具合の差に伴う濃淡差のある影が生じ、同時に第1の光強度よりも弱い第2の光強度の光を照射することにより透過基材(c2,c3)のエッジ(cE)の影を明確に作るこができる。そして、これらの影を撮像した画像から積層体(C)の内部構造および表面構造の検査を行うことが出来る。
なお、積層体(C)が例えば補強板付きフラットケーブルの場合、透過基材(c2,c3)は、例えば光の透過性のある絶縁体のテープ、または絶縁体のテープと接着剤層である。また、不透過部材(c1)は、導体(一般的に金属)、またはテンションメンバとして導体と並列に添えられるダミー線(一般的に金属)のような強度部材などである。また、半透過部材(c1)は、例えば伝送経路として用いる導波路(石英やポリイミドなど)である。また、透過部材(c5)は、補強板としてのテープ、またはテープと接着剤層である。
同様に、例えばフレキシブル回路基板のような積層体においても、光透過性の異なる部分に対して第1の光強度と第2の光強度を使い分けることにより、それぞれの部分を適正に検査できる。
すなわち、例えば補強板付きフラットケーブルのマージン及び補強板位置(表面構造)や導体のピッチ(内部構造)などの検査を1セットのカメラと照明および1つの画像解析装置により行うことが出来ると共に、補強板付きフラットケーブル以外の例えばフレキシブル回路基板のような積層体の透過画像による検査を1セットのカメラと照明および1つの画像解析装置により行うことが出来る。 In a first aspect, the present invention irradiates a first light intensity portion (1s) for irradiating light having a first light intensity and a light having a second light intensity that is weaker than the first light intensity. A non-transmissive member (c1) that does not transmit light to a transmissive base material (c2, c3) that can transmit light and a semi-transmissive material that is difficult to transmit light, using the illumination means having the second light intensity portion (1r) The second surface of the laminate (C) is irradiated with light from the first surface side of the laminate (C) formed by laminating at least one of the member (c1) and the transmissive member (c5) capable of transmitting light. A shadow of the member (c1, c5) is made to the side by the light of the first light intensity, and a shadow of the edge (cE) of the transmissive substrate (c2, c3) is made by the light of the second light intensity. Based on the shadows of the members (c1, c5) and the edges (cE), the laminate (C Provides a test method of a laminate which is characterized in that the inspection of the structure.
In the method for inspecting a laminate according to the first aspect, the first light intensity is not transmitted to the second surface side when light is applied from the first surface side of the flat cable (C) with a reinforcing plate, for example. The light intensity is such that the member (c1), the semi-transmissive member (c1), or the transmissive member (c5) can be shaded. Thereby, the position of the non-permeable member (c1) or the semi-transmissive member (c1) and the transmissive member (c5) can be inspected. However, at the first light intensity, the light wraps around at the edge portion, the edge does not appear properly on the image, and the margin cannot be inspected properly. Therefore, the second light intensity is set to be weaker than the first light intensity so that the phenomenon that the light wraps around the edge portion and the edge does not appear properly on the image can be suppressed. Thereby, since the shadow of edge (cE) can be made appropriately to the 2nd surface side of the flat cable (C) with a reinforcement board, a margin can also be test | inspected appropriately.
As illumination, the object to inspect the internal structure or surface structure of the laminate (C) is irradiated with the first light intensity, and the edge is irradiated with the second light intensity that is weaker than the first light intensity. So that the position of can be measured accurately.
Specifically, by irradiating the light of the first light intensity using the illumination means, a difference in transmittance or a difference in overlap between the non-transmissive member, the semi-transmissive member (c1), or the transmissive member (c5). A shadow with a difference in density is generated, and at the same time, the shadow of the edge (cE) of the transmissive substrate (c2, c3) is clearly made by irradiating light having a second light intensity that is weaker than the first light intensity. I can do this. And the internal structure and surface structure of a laminated body (C) can be test | inspected from the image which imaged these shadows.
In the case where the laminate (C) is, for example, a flat cable with a reinforcing plate, the transmissive base materials (c2, c3) are, for example, an insulating tape having light permeability, or an insulating tape and an adhesive layer. . The impermeable member (c1) is a conductor (generally metal) or a strength member such as a dummy wire (generally metal) attached in parallel with the conductor as a tension member. The semi-transmissive member (c1) is, for example, a waveguide (quartz, polyimide, etc.) used as a transmission path. The transmissive member (c5) is a tape as a reinforcing plate, or a tape and an adhesive layer.
Similarly, even in a laminated body such as a flexible circuit board, each portion can be properly inspected by properly using the first light intensity and the second light intensity for the portions having different light transmittance.
That is, for example, a margin of a flat cable with a reinforcing plate, a reinforcing plate position (surface structure), a conductor pitch (internal structure), and the like can be inspected by one set of camera and illumination and one image analysis device. An inspection using a transmission image of a laminate other than a flat cable with a plate, such as a flexible circuit board, can be performed with one set of camera, illumination, and one image analysis device.
上記第2の観点による積層体検査装置では、前記第1の観点による積層体の検査方法を好適に実施できる。 In a second aspect, the present invention irradiates a first light intensity portion (1s) for irradiating light having a first light intensity and a light having a second light intensity that is weaker than the first light intensity. A non-transmissive member (c1) that has a second light intensity portion (1r) for transmitting light and does not transmit light to the transparent base materials (c2, c3) that can transmit light, and a semi-transmissive member (c1) that is difficult to transmit light In addition, by irradiating light from the first surface side of the laminate (C) formed by laminating at least one of the transmissive members (c5) capable of transmitting light, the second surface side of the laminate (C) is irradiated with the first surface.

Provided is a laminate inspection apparatus (101, 102) characterized in that the light intensity is changed according to a difference.
In the laminate inspection apparatus (101, 102) according to the fifth aspect, for example, even when a reinforcing plate (c5) having different translucency is mixed in a flat cable with a reinforcing plate, it can automatically cope with it.

具体例を示すと、補強板付きフラットケーブルCの幅は20mmから60mm、部材c1の数は20本から80本、窓部c4の長さは8mmから30mm、補強板c5の色は「白」か「青」など色付き、補強板c5の長さは10mmから30mm、補強板c5の厚さは色「白」のものが60μm、色「青」のものが250μmなど設計により各種ある。 The flat cable C with a reinforcing plate has a basic structure in which a plurality of parallel conductors (or dummy wires and waveguides) c1 are sandwiched between a lower laminating tape c2 and an upper laminating tape c3 that are insulators. The upper laminate tape c3 is discontinuous, and a window portion c4 is provided at a predetermined location. Further, a reinforcing plate c5 for reinforcing the window c4 is attached to the lower laminate tape c2.
For example, the width of the flat cable C with a reinforcing plate is 20 to 60 mm, the number of members c1 is 20 to 80, the length of the window portion c4 is 8 to 30 mm, and the color of the reinforcing plate c5 is “white”. Or the color of the reinforcing plate c5 is 10 to 30 mm, the thickness of the reinforcing plate c5 is 60 μm for the color “white”, and 250 μm for the color “blue”.
減光板1bは、十字形のスリット1sを有している。このスリット1sを通る光の強度は面光源1aから出る光の強度であり、これを第1の光強度と呼ぶ。一方、スリット1s部分を除く減光板1bの部分1rを通る光の強度は面光源1aから出る光を減衰させた強度であり、これを第2の光強度と呼ぶ。 FIG. 2 is a top view of the
The
この時、スリット1sを通る光すなわち第1の光強度の光は、窓部c4のy方向長さの中央位置で補強板付きフラットケーブルCの最外側の導体c1の影を作りうるようにx方向の帯状領域で補強板付きフラットケーブルCを透過すると共に補強板c5の影を作りうるように窓部c4のx方向幅の中央付近の導体c1が無い位置でy方向に補強板c5のy方向長さより長い帯状領域で補強板付きフラットケーブルCを透過する。一方、スリット1s部分を除く減光板1bの部分1rを通る光すなわち第2の光強度の光は、補強板付きフラットケーブルCのエッジcEの影を作りうるように窓部c4のy方向外側で且つ窓部c4の近傍で且つ補強板付きフラットケーブルCのエッジ周辺に相当する領域で補強板付きフラットケーブルCを透過する。 FIG. 3 shows the moment when the window part c4 of the flat cable C with a reinforcing plate passes over the
At this time, the light passing through the slit 1 s, that is, the light having the first light intensity is x so that the shadow of the outermost conductor c <b> 1 of the flat cable C with the reinforcing plate can be made at the center position of the length in the y direction of the window c <b> 4. Y of the reinforcing plate c5 in the y direction at a position where there is no conductor c1 near the center of the width in the x direction of the window portion c4 so that the flat cable C with the reinforcing plate can pass through the belt-shaped region in the direction and the shadow of the reinforcing plate c5 can be made. The flat cable C with a reinforcing plate is transmitted through a belt-like region longer than the direction length. On the other hand, the light passing through the
スリット1sを通る光すなわち第1の光強度の光は、導体c1の影および補強板c5の影を明確に作っている。このため、導体c1の位置および補強板c5の位置は正確に読み取れる。しかし、窓部c4における補強板付きフラットケーブルCのエッジcEの影は不明確である。これは、補強板付きフラットケーブルCのエッジcEの影を明確に作るのには、第1の光強度が強すぎるからである。
一方、スリット1s部分を除く減光板1bの部分1rを通る光すなわち第2の光強度の光は、補強板付きフラットケーブルCのエッジcEの影を明確に作っている。このため、エッジcEの位置を正確に読み取れる。しかし、導体c1の影および補強板c5の影は不明確である。これは、導体c1の影および補強板c5の影を明確に作るのには、第2の光強度が弱すぎるからである。
従って、導体c1の影および補強板c5の影を明確に作り且つ補強板付きフラットケーブルCのエッジcEの影を明確に作るためには、第1の光強度および第2の光強度の両方が必要である。 FIG. 4 is a specific example of an image obtained by the
The light passing through the slit 1s, that is, the light having the first light intensity clearly forms the shadow of the conductor c1 and the shadow of the reinforcing plate c5. For this reason, the position of the conductor c1 and the position of the reinforcing plate c5 can be read accurately. However, the shadow of the edge cE of the flat cable C with a reinforcing plate in the window part c4 is unclear. This is because the first light intensity is too strong to clearly make the shadow of the edge cE of the flat cable C with a reinforcing plate.
On the other hand, the light passing through the
Therefore, in order to make the shadow of the conductor c1 and the shadow of the reinforcing plate c5 clearly and the shadow of the edge cE of the flat cable C with the reinforcing plate, both the first light intensity and the second light intensity are is necessary.

ステップR3では、下側センサ5により補強板5の色を検知する。補強板5の色は、例えば「白」または「青」の2種類である。
ステップR4では、補強板5の色に応じた照明強度を照明制御装置6に指示する。補強板5の色により透過度が異なるからである。例えば補強板5が「白」ならば「青」のときよりも透過度が高いので低い照明強度を指示し、「青」ならば「白」のときよりも透過度が低いので高い照明強度を指示する。照明制御装置6は、指示に応じて面光源1aの光強度を制御する。

e11: The x coordinate on the straight line y = y1 of the edge cE closer to the coordinate origin O. y1 is a y-coordinate of a position that is closer to the coordinate origin O than the window part c4 and is predicted that the shadow of the edge cE will be clear.
e12: The x coordinate on the straight line y = y1 of the edge cE closer to the coordinate origin O. y2 is a y-coordinate of a position that is farther from the coordinate origin O than the window c4 and is predicted to have a shadow of the edge cE.
e13: The x coordinate on the straight line y = y3 of the edge of the conductor c1 closest to the coordinate origin O on the side close to the coordinate origin O. y3 is the y coordinate of the position where the shadow of the conductor c1 is predicted to be clear in the window part c4.
e14: The x coordinate on the straight line y = y3 of the edge farthest from the coordinate origin O of the conductor c1 closest to the coordinate origin O.
e21: x coordinate on the straight line y = y1 of the edge cE far from the coordinate origin O.
e22: The x coordinate on the straight line y = y2 of the edge cE far from the coordinate origin O.
e23: The x coordinate on the straight line y = y3 of the edge of the conductor c1 farthest from the coordinate origin O on the side close to the coordinate origin O.
e24: x coordinate on the straight line y = y3 of the edge farthest from the coordinate origin O of the conductor c1 farthest from the coordinate origin O.
a1: A distance on the straight line x = x1 between the edge of the reinforcing plate c5 near the coordinate origin O and the edge of the window c4 near the coordinate origin O. x1 is the x coordinate of the position where the shadow of the upper laminate tape c3 and the shadow of the reinforcing plate c5 are predicted to be clear.
a2: Distance on the straight line x = x1 between the edge of the reinforcing plate c5 far from the coordinate origin O and the edge of the window c4 far from the coordinate origin O.
w: The width of the window part c4 on the straight line x = x1.
b1=(-e11-e12+e13+e14)/2
b2=(-e21-e22+e23+e24)/2
マージンb1,b2の規定値は、例えば2.5mmである。 In step S4, margins b1 and b2 are calculated.
b1 = (− e11−e12 + e13 + e14) / 2
b2 = (− e21−e22 + e23 + e24) / 2
The specified value of the margins b1 and b2 is, for example, 2.5 mm.
そして、次の窓部c4を処理するため、ステップS1に戻る。
この場合、カメラのX,Y軸と積層体(C)のX,Y軸をあらかじめ合わせておく必要がる。また各座標は二次元カメラを使用する場合は、例えばe11を求めるためにy1の1点で測定するのではなくy1の近傍のある範囲(10から100画素)での平均値を取ることで測定精度を大幅に改善できる。他の位置も同様に範囲を決めて測定し平均化を図ることが好ましい。 In step S5, the margins b1, b2 and the measured values a1, a2, w are output to a storage device, a display device, and a printer.
And in order to process the next window part c4, it returns to step S1.
In this case, the X and Y axes of the camera and the X and Y axes of the laminate (C) must be aligned in advance. In addition, when using a two-dimensional camera, each coordinate is measured by taking an average value in a certain range (10 to 100 pixels) in the vicinity of y1 instead of measuring at one point y1 to obtain e11, for example. The accuracy can be greatly improved. It is preferable that the other positions are similarly measured and averaged by determining the range.
この場合、上側センサ4は窓部c4毎に交互に窓部センサとして機能したり補強板センサとして機能し、下側センサ5は上側センサ4が窓部センサとして機能する時は補強板センサとして機能し、上側センサ4が補強板センサとして機能する時は窓部センサとして機能する。

In this case, the
