Description

本発明は制御基板の端子電極に異方性導電膜を介して圧着されたフレキシブル基板(TAB部品、TCP、FPC、SOF等)の端子電極の圧着状態を検査する装置に関する。
さらに詳しくは、制御基板の端子電極とフレキシブル基板の端子電極とを異方性導電膜を介して圧着する際にフレキシブル基板の端子電極に生じた異方性導電膜中の導電粒子による圧痕状態及び/または端子電極同士の位置ずれ状態を検査する装置に関する。
The present invention relates to an apparatus for inspecting the crimping state of a terminal electrode of a flexible substrate (TAB component, TCP, FPC, SOF, etc.) that is crimped to a terminal electrode of a control substrate via an anisotropic conductive film.
More specifically, when the terminal electrode of the control board and the terminal electrode of the flexible board are pressure-bonded via the anisotropic conductive film, the indentation state due to the conductive particles in the anisotropic conductive film generated on the terminal electrode of the flexible board and The present invention relates to an apparatus for inspecting a misalignment state between terminal electrodes.

従来より、液晶パネルの製造工程において、液晶ガラス基板の端子電極に異方性導電膜を貼り付けた後、フレキシブル基板の端子電極と液晶ガラス基板の端子電極とを圧着し、続いてフレキシブル基板のもう一方の端子電極を異方性導電膜を介して制御基板に圧着して液晶パネルが製造される。この後、導通検査等が行われ、その後の工程に供される。  Conventionally, in the manufacturing process of a liquid crystal panel, after attaching an anisotropic conductive film to a terminal electrode of a liquid crystal glass substrate, the terminal electrode of the flexible substrate and the terminal electrode of the liquid crystal glass substrate are pressure-bonded, and then the flexible substrate The other terminal electrode is pressure-bonded to the control substrate via an anisotropic conductive film to produce a liquid crystal panel. Thereafter, a continuity test or the like is performed, and the subsequent process is performed.

ところで、この導通検査においては電気的な接続状態の良否を判定しているが、圧着時の圧力や熱のばらつきによっては、圧着直後に電気的な接続が良好であっても経時的に接続状態が不良となる場合がある。このため、本圧着後、圧着時の圧力や加熱が適正であったかどうかや圧着時の制御基板の端子電極とフレキシブル基板の端子電極の位置ずれの状態等、各種の圧着状態の検査を行う必要がある。  By the way, in this continuity test, the quality of the electrical connection state is judged, but depending on the pressure and heat variations during crimping, even if the electrical connection is good immediately after crimping, the connection state over time May become defective. For this reason, after the main crimping, it is necessary to inspect various crimping conditions such as whether the pressure and heating at the time of crimping are appropriate and the position of the terminal electrode of the control board and the flexible board at the time of crimping. is there.

そこで、制御基板側に圧着されたフレキシブル基板の圧着状態の検査は、従来から、図10のようにフレキシブル基板2表面の斜め上方から光源36で光を照射し、斜め上方から肉眼35でフレキシブル基板2表面の凹凸を目視して良否の判定をする方法が行われている。また、これを自動化するために偏光板表面の異物検査で行われているようなラインセンサを利用してフレキシブル基板の表面の凹凸を検査する手法も考えられる。  Therefore, conventionally, the inspection of the crimped state of the flexible substrate crimped to the control substrate side is performed by irradiating light from the light source 36 obliquely above the surface of the flexible substrate 2 as shown in FIG. 2. A method of judging the quality by visually checking the unevenness on the surface is performed. In order to automate this, a method of inspecting the irregularities on the surface of the flexible substrate using a line sensor which is performed in the foreign matter inspection on the polarizing plate surface is also conceivable.

また、液晶ガラス基板側に圧着されたフレキシブル基板の圧着状態の検査としては、圧着により液晶ガラス基板の端子電極に異方性導電膜の導電粒子が押し付けられることによって生じた液晶ガラス基板の端子電極の圧痕をガラス基板を介して下方から微分干渉顕微鏡を通してCCDカメラで撮像し、指定された範囲に存在する圧痕数から良否判定することが行われている(例えば特許文献1)。

In addition, as an inspection of the crimped state of the flexible substrate crimped to the liquid crystal glass substrate side, the terminal electrode of the liquid crystal glass substrate generated by pressing the conductive particles of the anisotropic conductive film against the terminal electrode of the liquid crystal glass substrate by the crimping The indentation is imaged by a CCD camera through a differential interference microscope from below through a glass substrate, and the quality is determined from the number of indentations existing in a specified range (for example, Patent Document 1).
JP 2005-227217 A

しかし、上記のような目視による検査は最近の液晶パネルの大型化に伴い、取り扱いが困難であり、また、検査面積も増大し、さらに基板の撓みも加わって正確に判断することが困難となってきている。  However, the visual inspection as described above is difficult to handle with the recent increase in size of the liquid crystal panel, and the inspection area is increased, and further, it is difficult to accurately judge due to the bending of the substrate. It is coming.

また、肉眼でフレキシブル基板表面の凹凸を見る方法は、端子電極部分を直接見ているのではないため、間接的な判定しか行えない問題や、自動化されていないことによる判定のばらつきがある。  In addition, the method of viewing the surface of the flexible substrate with the naked eye does not look directly at the terminal electrode portion, and therefore has a problem that only indirect determination can be made, and there are variations in determination due to not being automated.

さらに、ラインセンサを使用する方法も上記同様に端子電極部分を直接見ているのではないため、間接的な判定しか行えない問題や、フレキシブル基板と制御基板の端子電極同士の位置ずれを検査することができない問題があった。さらに、フレキシブル基板が柔軟性を持つことから、表面の変形にばらつきが多く、判定条件を決定することが困難であり、良否判定が安定しない問題があった。  Furthermore, since the method using the line sensor does not directly look at the terminal electrode portion in the same manner as described above, the problem that only indirect determination can be made and the positional deviation between the terminal electrodes of the flexible substrate and the control substrate are inspected. There was a problem that could not be done. Furthermore, since the flexible substrate has flexibility, there are many variations in the deformation of the surface, it is difficult to determine the determination conditions, and the quality determination is not stable.

また、特許文献1の方法は、異方性導電膜の導電粒子による液晶ガラス基板の端子電極に生じた圧痕を、液晶ガラス基板を透過させて微分干渉顕微鏡を通してCCDカメラで撮像し、その圧痕数等から良否を判定している。  In the method of Patent Document 1, an impression generated on the terminal electrode of the liquid crystal glass substrate by the conductive particles of the anisotropic conductive film is transmitted through the liquid crystal glass substrate and imaged with a CCD camera through a differential interference microscope, and the number of the impressions is measured. The quality is judged from the above.

しかし、制御基板側に圧着された制御基板の端子電極は制御基板が液晶ガラス基板のように透明に形成されていないため、制御基板を介して検査できず、上記特許文献1の方法を適用することができない問題があった。  However, the terminal electrode of the control board crimped to the control board side cannot be inspected through the control board because the control board is not formed transparent like the liquid crystal glass substrate, and the method of Patent Document 1 is applied. There was a problem that could not be done.

ここで、上記特許文献1の方法をフレキシブル基板側からフレキシブル基板を透過させて検査を行うように適用した場合、フレキシブル基板はその柔軟性から圧着時の変形量が、液晶ガラス基板とは異なって、大きいため微分干渉顕微鏡では導電粒子による端子電極の圧痕以外の凹凸が強調され過ぎて検査できない問題がある。さらに、微分干渉顕微鏡は高価であり、特定部位を強調させて見るようにするため、高倍率(通常5倍以上)で視野が狭く、広範囲を見るには適していない。このため、検査対象の端子電極が多い場合に検査範囲が狭く、検査回数が増えるため時間を要す問題があった。  Here, when the method of the above-mentioned Patent Document 1 is applied so as to inspect by allowing the flexible substrate to pass through from the flexible substrate side, the flexible substrate is different from the liquid crystal glass substrate in the amount of deformation at the time of crimping due to its flexibility. Because of the large size, the differential interference microscope has a problem in that the unevenness other than the indentation of the terminal electrode due to the conductive particles is excessively emphasized and cannot be inspected. Furthermore, the differential interference microscope is expensive, and a specific part is emphasized for viewing, so that the field of view is narrow at a high magnification (usually 5 times or more) and is not suitable for viewing a wide range. For this reason, when there are many terminal electrodes to be inspected, there is a problem that the inspection range is narrow and the number of inspections increases, which requires time.

また、通常の圧着時における制御基板とフレキシブル基板の端子電極同士の位置合わせは、図6を参照して説明すると、既に液晶ガラス基板側に複数のフレキシブル基板2が圧着された状態で制御基板3上に供給されるため、各フレキシブル基板毎には行われておらず、制御基板3の両端に設けられたアライメントマーク24と液晶ガラス基板の両端に位置するアライメントマーク(図示しない)の2箇所を所定の位置に合わせて複数のフレキシブル基板2と制御基板3を一括に圧着している。  In addition, the alignment between the terminal electrodes of the control board and the flexible board during normal crimping will be described with reference to FIG. 6. The control board 3 in a state where the plurality of flexible boards 2 are already crimped to the liquid crystal glass substrate side. Since it is supplied to the upper side, it is not performed for each flexible substrate, and two positions of an alignment mark 24 provided at both ends of the control substrate 3 and alignment marks (not shown) located at both ends of the liquid crystal glass substrate are provided. The plurality of flexible boards 2 and the control board 3 are pressure-bonded together at a predetermined position.

上記、圧着後に各フレキシブル基板2の両端に設けられたアライメントマーク26a、26bとそれに対向する位置に設けられた制御基板3側のアライメントマーク27a、27bがずれていないか目視、又は光学的な検査が行われている。  Visually or optically inspected whether the alignment marks 26a and 26b provided at both ends of each flexible substrate 2 after the crimping and the alignment marks 27a and 27b on the control substrate 3 provided at the opposite positions are not shifted. Has been done.

しかし、上記の方法は、アライメントマーク部分のみの検査であり、複数の端子電極毎には行われておらず、最近の端子電極の細ピッチ化により、アライメントマーク部の位置合わせに問題が無くとも、アライメントマーク自体の誤差、ピッチ毎の累積誤差、一部の端子電極の変形等により接続不良が発生する場合があった。さらに、上記の検査は独立して、個々に行われているため、時間を要する問題があった。  However, the above method is an inspection of only the alignment mark portion, and is not performed for each of the plurality of terminal electrodes. Even if there is no problem in alignment of the alignment mark portion due to the recent finer pitch of the terminal electrodes. In some cases, poor connection may occur due to errors in the alignment marks themselves, accumulated errors for each pitch, deformation of some terminal electrodes, and the like. Furthermore, since the above inspections are performed independently, there is a problem that takes time.

以上のように、上記方法はいずれの場合も問題が有り、制御基板側に圧着されたフレキシブル基板の圧着状態を適正に検査する方法はなく、経時的な劣化に対して対応できない問題があった。また、圧痕と位置ずれを同時に検査することができない問題があった。さらに、不良が発生しても、記憶した情報が圧着装置にフィードバックされないため、不良発生時に手動で圧着装置の調整が必要であり、調整に時間を要す問題があった。  As described above, there is a problem in any of the above methods, there is no method for properly inspecting the crimped state of the flexible substrate that is crimped to the control substrate side, and there is a problem that it is not possible to cope with deterioration over time. . Further, there is a problem that the indentation and the positional deviation cannot be inspected at the same time. Furthermore, even if a failure occurs, the stored information is not fed back to the crimping device, so that it is necessary to manually adjust the crimping device when the failure occurs, and there is a problem that it takes time for the adjustment.

そこで、本発明は制御基板に圧着されたフレキシブル基板の圧着状態を精度良く検査するとともに、位置ずれの検査も同一工程で実施できる圧着状態検査装置を提供すること及び圧着状態の検査結果を圧着装置に反映させ、圧着精度を自動的に向上させることができる圧着状態検査装置を提供することにある。  Accordingly, the present invention provides a crimping state inspection device capable of accurately inspecting the crimping state of a flexible substrate that is crimped to a control substrate, and that can also perform misalignment inspection in the same process, and crimping state inspection results. It is an object of the present invention to provide a crimping state inspection apparatus capable of automatically improving the crimping accuracy.

The nut member 12 is connected through the nut member 12, and the nut member 12 is engaged with the ball screw 11 so that the motor 7 can be moved up and down.

機台4上には、圧着装置により制御基板3が接続された液晶パネル1が所定の位置に供給されるようになっており、供給された液晶パネル1は吸着、固定アーム等、図示しない適宜な固定機構で固定されるようになっている。  On the machine base 4, the liquid crystal panel 1 to which the control board 3 is connected by a crimping device is supplied to a predetermined position. It is designed to be fixed by a simple fixing mechanism.

次に図3(a)、(b)に従って本発明の検査装置について説明する。CCDカメラ5には、同軸落射照明13が接続され、ファイバー照明14と接続された光源(図示しない)から照射された光をハーフミラー15で反射させ、図示しないレンズを通して平行光16を、検査するフレキシブル基板の端子電極17部分にフレキシブル基板2を介して照射するようになっている。  Next, the inspection apparatus of the present invention will be described with reference to FIGS. 3 (a) and 3 (b). A coaxial epi-illumination 13 is connected to the CCD camera 5. Light emitted from a light source (not shown) connected to the fiber illumination 14 is reflected by a half mirror 15, and the parallel light 16 is inspected through a lens (not shown). The terminal electrode 17 portion of the flexible board is irradiated through the flexible board 2.

フレキシブル基板2を通して端子電極17部分に照射された平行光16は、端子電極17の表層部に反射し、反射された平行光16はハーフミラー15を透過し、CCDカメラ5で撮像されるようになっている。  The parallel light 16 irradiated to the terminal electrode 17 portion through the flexible substrate 2 is reflected on the surface layer portion of the terminal electrode 17, and the reflected parallel light 16 passes through the half mirror 15 and is imaged by the CCD camera 5. It has become.

本発明の検査装置は上記のような構成であり、次に本発明の検査装置を用いた検査方法について説明する。  The inspection apparatus according to the present invention is configured as described above. Next, an inspection method using the inspection apparatus according to the present invention will be described.

まず、圧着装置で液晶パネル1とフレキシブル基板2とが異方性導電膜21を介して圧着され、続いて図4(a)のように制御基板3の端子電極18上に異方性導電膜21を貼り付けておき、その上に液晶パネル1と接続されたフレキシブル基板2の端子電極17を対向させて、図4(a)の矢印のように圧着を行う。  First, the liquid crystal panel 1 and the flexible substrate 2 are pressure-bonded via the anisotropic conductive film 21 by a pressure bonding device, and then the anisotropic conductive film is formed on the terminal electrode 18 of the control substrate 3 as shown in FIG. 21 is pasted, and the terminal electrode 17 of the flexible substrate 2 connected to the liquid crystal panel 1 is opposed thereto, and crimping is performed as shown by an arrow in FIG.

このように圧着の完了した液晶パネル1は本発明の検査装置の機台4上の検査部に適宜な搬送手段(図示しない)で位置決め供給され、適宜な固定機構(図示しない)で液晶パネル1及び制御基板3が固定される。  The liquid crystal panel 1 that has been crimped in this way is positioned and supplied to the inspection section on the machine base 4 of the inspection apparatus of the present invention by an appropriate conveying means (not shown), and the liquid crystal panel 1 is supplied by an appropriate fixing mechanism (not shown). And the control board 3 is fixed.

上記液晶パネル1が固定されると、検査対象であるフレキシブル基板2の端子電極17上の検査位置まで、検査手段34を駆動させ、検査位置まで移動した検査手段34はファイバー照明14から入射される光を同軸落射照明13にて平行光16としてフレキシブル基板2の制御基板3側の端子電極部17上に照射する。  When the liquid crystal panel 1 is fixed, the inspection means 34 is driven to the inspection position on the terminal electrode 17 of the flexible substrate 2 to be inspected, and the inspection means 34 moved to the inspection position is incident from the fiber illumination 14. Light is irradiated on the terminal electrode portion 17 on the control board 3 side of the flexible board 2 as parallel light 16 by the coaxial incident illumination 13.

照射された平行光16はフレキシブル基板2を透過し、端子電極17の上方に到達し、端子電極17の表面に反射した光がハーフミラー15を透過してCCDカメラ5に圧痕22部分の形状や隆起の状態が撮像される。  The irradiated parallel light 16 passes through the flexible substrate 2 and reaches above the terminal electrode 17, and the light reflected on the surface of the terminal electrode 17 passes through the half mirror 15 and passes through the half mirror 15 to the CCD camera 5. The state of the bulge is imaged.

なお、この時使用する平行光16はフレキシブル基板2自体の透過性が良い場合は可視光を使用することができ、透過性が劣るフレキシブル基板2を使用する場合は、透過性の良い光源(例えば赤色光、赤外光)を用いることができる。なお、これらに限定されること無く、フレキシブル基板2の着色に応じて適宜選択できる。  As the parallel light 16 used at this time, visible light can be used when the flexible substrate 2 itself has good transparency, and when the flexible substrate 2 with poor transparency is used, a light source with good transparency (for example, Red light, infrared light) can be used. In addition, it can select suitably according to coloring of the flexible substrate 2, without being limited to these.

また、透過性に応じて、同軸落射照明16の照射強度を調整したり、同軸落射照明16による平行光16以外に補助的に撮像する部分を補助光源(図示しない)で照射するようにしたりしても良い。  Further, the irradiation intensity of the coaxial epi-illumination 16 is adjusted in accordance with the transparency, or a portion to be supplementarily imaged in addition to the parallel light 16 by the coaxial epi-illumination 16 is illuminated by an auxiliary light source (not shown). May be.

また、同軸落射照明13部分に用いるレンズはフレキシブル基板2を透過し、端子電極17部分から反射してきた光をCCDカメラ5により多く集光できるよう、集光率の高いレンズを使用することが好ましい。また、検査範囲を広く取り、検査効率を向上させる観点から低倍率のレンズ(例えば2倍程度)を好ましく使用できる。  In addition, it is preferable to use a lens having a high condensing rate so that the lens used for the coaxial epi-illumination 13 can transmit a large amount of light transmitted through the flexible substrate 2 and reflected from the terminal electrode 17 by the CCD camera 5. . Moreover, a low magnification lens (for example, about 2 times) can be preferably used from the viewpoint of widening the inspection range and improving the inspection efficiency.

図6(a)、(b)は検査対象となる制御基板3とフレキシブル基板2を圧着した検査部分付近の拡大平面図である。  FIGS. 6A and 6B are enlarged plan views of the vicinity of the inspection portion where the control substrate 3 to be inspected and the flexible substrate 2 are pressure-bonded.

制御基板3には液晶パネル1をベセルへ組み込む際に制御基板3を固定するための固定穴25が設けられ、フレキシブル基板2を接続するための端子電極18が設けられている。また、圧着時に液晶パネル1と位置合わせを行うためのアライメントマーク24が制御基板3の両端部分に設けられており、通常、液晶パネル1側のアライメントマーク(図示しない)と前記アライメントマーク24を適宜な光学手段で所定の位置に位置合わせし、複数のフレキシブル基板2と制御基板3が一括で圧着される。  The control board 3 is provided with a fixing hole 25 for fixing the control board 3 when the liquid crystal panel 1 is assembled into the vessel, and a terminal electrode 18 for connecting the flexible board 2. In addition, alignment marks 24 for aligning with the liquid crystal panel 1 at the time of pressure bonding are provided at both end portions of the control substrate 3. Usually, an alignment mark (not shown) on the liquid crystal panel 1 side and the alignment mark 24 are appropriately attached. The plurality of flexible boards 2 and the control board 3 are collectively pressure-bonded by aligning at a predetermined position with an optical means.

前記撮像する部分に画像枠33が設定され、撮像された画像を公知な画像処理法(例えば2値化、微分処理)で画像処理して表示手段(図示しない)に画面表示される。  An image frame 33 is set in the portion to be imaged, and the captured image is subjected to image processing by a known image processing method (for example, binarization and differentiation processing) and displayed on a display means (not shown).

図7(a)は圧着状態が良好な一例であり、各端子電極17部分に判定枠32が設定され、良否判定は判定枠32中のフレキシブル基板2の端子電極17の変形状態データ(存在する圧痕22の数や形状、濃淡等)を予め設定しておいた良否判定データと比較して良否判定するようになっている。  FIG. 7A is an example in which the crimped state is good, and a determination frame 32 is set in each terminal electrode 17 portion, and the pass / fail determination is performed by deformation state data (existing state) of the terminal electrode 17 of the flexible substrate 2 in the determination frame 32. The pass / fail judgment is made in comparison with the pass / fail judgment data set in advance such as the number and shape of the indentations 22 and the shading.

なお、前記のように圧痕22の形状、濃淡から判定することにより、圧痕22が導電粒子20ではなく、異物によるものであっても、予め正常な圧痕22の形状や濃淡を設定しておけば、正常な状態との対比で異物の判定にも利用できる。  Note that, by determining from the shape and density of the indentation 22 as described above, even if the indentation 22 is not due to the conductive particles 20 but is due to foreign matter, the normal shape and density of the indentation 22 can be set in advance. In comparison with the normal state, it can also be used for foreign matter determination.

図7(b)は圧着状態が不良である一例であり、この場合は前記良品のものに比べ圧痕22の数が少なく、圧着時の圧力や加熱が弱かったことが判定枠32中のフレキシブル基板2の端子電極17の変形状態データとして検出できる。この変形状態データを予め設定しておいた良否判定データと比較し、不良と判定されたものは修正工程に供され修正されることになる。  FIG. 7B is an example in which the crimped state is poor. In this case, the number of the indentations 22 is smaller than that of the good product, and the flexible substrate in the determination frame 32 indicates that the pressure and heating during the crimping are weak. It can be detected as deformation state data of the two terminal electrodes 17. The deformation state data is compared with the quality determination data set in advance, and those determined as defective are subjected to a correction process and corrected.

また、上記圧痕22による良否判定時には図8のように同一画像中にフレキシブル基板2の端子電極17のエッジ部28と制御基板3の端子電極18のエッジ部29が写し出されている。このエッジ部28、29の距離d1、d2及びd3、d4を測定することにより、端子電極同士の位置ずれ量が各端子電極毎に算出できる。  Further, when determining the quality by the indentation 22, the edge portion 28 of the terminal electrode 17 of the flexible substrate 2 and the edge portion 29 of the terminal electrode 18 of the control substrate 3 are shown in the same image as shown in FIG. By measuring the distances d1, d2 and d3, d4 of the edge portions 28, 29, the amount of positional deviation between the terminal electrodes can be calculated for each terminal electrode.

この位置ずれ量を予め許容される位置ずれ量として設定された基準位置ずれ量と比較し、位置ずれ状態の良否を判定し、不良と判定されれば修正工程等に供される。  This misregistration amount is compared with a reference misregistration amount set as a permissible misregistration amount in advance to determine whether the misregistration state is good or not.

なお、本実施例では制御基板3側の端子電極18がフレキシブル基板2の端子電極17よりも大きい一般的な例を挙げたが、同一幅、逆の場合であっても適用できる。また、エッジ部28、29の距離だけでなく角度等測定するようにしても良い。  In the present embodiment, the general example in which the terminal electrode 18 on the control board 3 side is larger than the terminal electrode 17 on the flexible board 2 has been described. Further, not only the distance between the edge portions 28 and 29 but also an angle or the like may be measured.

なお、本実施例では圧痕検査画面と、エッジ部28、29を同時に映し出すようにしたが、焦点との関係によっては別々に焦点を合わせても良く、この検査工程内で圧痕検査と位置ずれ検査の両方を行えれば良い。  In this embodiment, the indentation inspection screen and the edge portions 28 and 29 are projected at the same time. However, depending on the relationship with the focal point, the focus may be adjusted separately. You can do both.

ここで、端子電極17、18に許容範囲以上の位置ずれがあった場合は不良品の修正工程へ供され修正されることになる。  Here, if the terminal electrodes 17 and 18 have a positional deviation exceeding the allowable range, they are subjected to a defective product correction process and corrected.

次に本発明の別の実施形態について図9のフロー図に基づいて説明する。  Next, another embodiment of the present invention will be described based on the flowchart of FIG.

前記圧着状態検査装置の近傍に圧着装置が設けられ、両装置の制御部を通じて通信可能となっており、圧着装置には位置決め手段と圧着手段が設けられ、制御部を通じて圧着条件が制御されるようになっている。  A crimping device is provided in the vicinity of the crimping state inspection device, and communication is possible through the control unit of both devices. The crimping device is provided with positioning means and crimping means, and the crimping conditions are controlled through the control unit. It has become.

前記圧着装置においては、まず、液晶パネル1上のフレキシブル基板2と制御基板3が位置決めされ、圧着手段で圧着される。  In the crimping apparatus, first, the flexible substrate 2 and the control substrate 3 on the liquid crystal panel 1 are positioned and crimped by a crimping means.

圧着が完了したフレキシブル基板2と制御基板3は適宜な撮像手段(CCDカメラ5)で撮像され、画像処理部で2値化やエッジ処理等公知な画像処理法で画像処理が行われ、良否判定部で上記と同様に良否判定が行われる。  The flexible substrate 2 and the control substrate 3 that have been crimped are imaged by an appropriate imaging means (CCD camera 5), and image processing is performed by a known image processing method such as binarization or edge processing in an image processing unit, and pass / fail judgment is made. The pass / fail judgment is performed in the same manner as described above.

良否判定が行われた後、良否判定データ(例えば圧痕数、圧痕形状、圧痕の濃淡、位置ずれ量)及び画像データ(画像処理前の生画像、画像処理後の画像)が記憶部に記憶され、各種データの解析(例えば複数データの標準偏差からの分析)が行われる。  After the pass / fail judgment is made, pass / fail judgment data (for example, the number of impressions, the shape of the impression, the density of the impression, the amount of displacement) and image data (raw image before image processing, image after image processing) are stored in the storage unit. Analysis of various data (for example, analysis from standard deviation of a plurality of data) is performed.

この解析された良否判定データは圧着状態検査装置の制御部を通じて圧着装置の制御部にフィードバックされ、圧着装置は良否判定データを元に例えば圧力が弱いと判断すれば、圧力設定を強める等の制御を行うようになっている。  The analyzed pass / fail judgment data is fed back to the control unit of the crimping device through the control unit of the crimping state inspection device, and if the crimping device determines, for example, that the pressure is weak based on the pass / fail judgment data, control such as increasing the pressure setting. Is supposed to do.

また、同様に位置ずれが一定方向にずれていれば、位置決め時の角度、移動量に補正をかけるように圧着装置の制御部に位置決め設定条件をフィードバックするようになっている。  Similarly, if the positional deviation is deviated in a certain direction, the positioning setting condition is fed back to the control unit of the crimping apparatus so as to correct the angle and movement amount during positioning.

圧着状態の検査が終了した製品は検査が良品であれば次の工程へ搬送され、不良品であれば修正工程へ搬送するようにすれば良い。  A product that has been inspected in a crimped state may be transported to the next process if the inspection is a non-defective product, and transported to a correction process if the product is defective.

なお、本実施例では圧着状態検査装置での良否判断データ及び画像データから分析した情報を圧着装置にフィードバックするようにしたが、上記データを圧着状態検査装置に記憶しておくことで、以後の検査に反映させることも可能であり、このようにすることで検査の良否判断基準を精度良く行うようにすることが可能となる。  In this embodiment, the information analyzed from the pass / fail judgment data and the image data in the crimping state inspection device is fed back to the crimping device. However, by storing the data in the crimping state inspection device, It is also possible to reflect it in the inspection, and in this way, it is possible to accurately perform the quality determination criteria for the inspection.
