Abstract

This terminal crimping defect detection device makes it possible to achieve more highly precise determination by effectively combining a determination result from a pressure management device and a determination result from an image detection device. A pressure management device 3 uses a pressure sensor 1 provided to a terminal crimping device to acquire waveform data for one instance of crimping output from the pressure sensor 1 during terminal crimping, then determines terminal crimping quality. An image detection device 5 uses a camera 4 to capture image data of an end of a terminal-equipped electrical wire 8 and uses the image data as a basis to determine terminal crimping quality. Each time crimping work is performed on an individual terminal-equipped electrical wire, the image data used for determination and the determination result are transmitted from the image detection device 5 to an overall determination device 9, and the determination result is transmitted from the pressure management device 3 to the overall determination device 9. The overall determination device 9 performs overall determination using the determination result of the image detection device 5 when the received image data is a suitable image that is not out of focus or the like. The overall determination device 9 performs overall determination using the determination result of the pressure management device 3 when the received image data is not suitable.

Description

端子圧着不良検出装置Terminal crimp failure detection device
　本発明は、被覆を剥離した絶縁被覆電線の端末に、自動式又は手動式の端子圧着装置により端子を圧着する際に、端子の圧着状態を監視して圧着不良を自動的に検出するための端子圧着不良検出装置に関するものである。 The present invention is for automatically detecting a crimping failure by monitoring a crimping state of a terminal when crimping a terminal to an end of an insulation coated electric wire from which a coating has been peeled off by an automatic or manual terminal crimping device. The present invention relates to a terminal crimping failure detection device.
　自動式の端子圧着装置は、所定の長さに切断され、端部被覆が一定長だけ剥離された被覆電線と、所定形状の端子とを端子圧着装置に送り込み、電線の端部に端子を装着してベース板上のアンビルに載置する。その状態で、上からクリンパーをアンビル上の端子に押し付けることにより端子を所定の形状に圧縮する。そのような動作を連続的に繰り返して、多量の端子付き電線を自動的に製造する。また、手動式の端子圧着装置では、操作者が、所定形状の端子を所定の位置にセットし、その端子に合わせて、所定の長さに切断され、端部被覆が一定長だけ剥離された被覆電線を手で保持し、足下のスイッチで圧着装置を作動させて端子を圧着させる。 An automatic terminal crimping device feeds a coated wire, which has been cut to a predetermined length and the end coating has been peeled off by a fixed length, and a terminal with a predetermined shape to the terminal crimping device, and the terminal is attached to the end of the wire. And place it on the anvil on the base plate. In this state, the terminal is compressed into a predetermined shape by pressing the crimper against the terminal on the anvil from above. Such an operation is continuously repeated to automatically manufacture a large amount of electric wires with terminals. Further, in the manual type terminal crimping apparatus, an operator sets a terminal having a predetermined shape at a predetermined position, is cut into a predetermined length according to the terminal, and the end cover is peeled off by a certain length. Hold the covered wire by hand and operate the crimping device with the switch under the foot to crimp the terminal.
　図５は、自動式の端子圧着装置を示す図である。図５において、１は圧力センサ、１１はベース板、１２，１２はアプリケータ、１３，１３はクリンパー、１４はアンビル、１５は被覆電線、１６は電線導体、１７は端子、１８はワイヤバレル、１９は絶縁バレル、２０はリード線である。 FIG. 5 is a diagram showing an automatic terminal crimping apparatus. In FIG. 5, 1 is a pressure sensor, 11 is a base plate, 12 and 12 are applicators, 13 and 13 are crimpers, 14 is an anvil, 15 is a covered wire, 16 is a wire conductor, 17 is a terminal, 18 is a wire barrel, Reference numeral 19 is an insulating barrel, and 20 is a lead wire.
　端子圧着装置では、所定の長さに切断され、端部被覆が一定長だけ剥離して電線導体１６が露出された被覆電線１５と、ワイヤバレル１８と絶縁バレル１９とを有する端子１７とを送り込み、電線の端部に端子を装着してアンビル１４の上に載置する。その状態で、上方のアプリケータ１２を押し下げて、アプリケータ下端に設けたクリンパー１３，１３を、それぞれ、端子１７のワイヤバレル１８と絶縁バレル１９に押し付けることによりそれらを所定の形状に圧縮する。 In the terminal crimping apparatus, the coated electric wire 15 which is cut to a predetermined length, the end covering is peeled by a certain length and the electric wire conductor 16 is exposed, and the terminal 17 having the wire barrel 18 and the insulating barrel 19 are fed. The terminal is mounted on the end of the electric wire and placed on the anvil 14. In this state, the upper applicator 12 is pushed down, and the crimpers 13 and 13 provided at the lower end of the applicator are pressed against the wire barrel 18 and the insulating barrel 19 of the terminal 17 to compress them into a predetermined shape.
　その結果、クリンパー１３，１３とアンビル１４とにより、端子１７のワイヤバレル１８が電線導体１６を包み込むように圧縮され、絶縁バレル１９が、被覆電線１５の絶縁被覆の端部を包み込むように圧縮されて、被覆電線１５に端子１７が強固に接続固定される。端子圧着装置は、そのような動作を連続的に繰り返して、端子付き電線を自動的に製造する。 As a result, the crimper 13, 13 and the anvil 14 compress the wire barrel 18 of the terminal 17 so as to wrap the wire conductor 16, and the insulating barrel 19 is compressed so as to wrap the end of the insulating coating of the covered wire 15. Thus, the terminal 17 is firmly connected and fixed to the covered electric wire 15. The terminal crimping device continuously repeats such an operation to automatically manufacture a terminal-attached electric wire.
　このような端子圧着装置においては、浅打ち：絶縁バレル１９が被覆電線１５の絶縁被覆を把持する位置が浅すぎる、深打ち：絶縁バレル１９が被覆電線１５の絶縁被覆を把持する位置が深すぎる、絶縁バレル１９の内折れ、外折れ：本来は絶縁被覆の上にあるべき絶縁バレル１９が、内側や外側に折れ曲がっている、芯線こぼれ：本来何もない部分に芯線の一部がはみ出している、ストリップミス：端子１７を圧着する前に、被覆電線１５の端部絶縁被覆を剥離した際、剥離した長さが規格外になっている、というような圧着不良が発生することがあり、そのような圧着不良が発生したら、それを検知して排除する必要がある。また、手動式の端子圧着装置においても同様である。 In such a terminal crimping device, shallow punching: the position where the insulating barrel 19 grips the insulating coating of the covered wire 15 is too shallow, deep hitting: the position where the insulating barrel 19 grips the insulating coating of the coated wire 15 is too deep. Insulation barrel 19 folds in and out: Insulation barrel 19 that should originally be on the insulation coating is bent inwardly or outwardly, core wire spills: A part of the core wire protrudes from an originally empty part , Strip Miss: When the end insulation coating of the coated electric wire 15 is peeled before the terminal 17 is crimped, a crimping failure such that the peeled length is out of specification may occur. If such a crimp failure occurs, it must be detected and eliminated. The same applies to a manual terminal crimping apparatus.
　そこで、圧力センサ，歪センサ等のセンサにより端子圧着時の異常を検出して圧着状態を識別し、圧着不良を自動的に検知する技術が開発された。圧力センサの取付箇所としては、図５に示すような端子圧着装置のベース板１１の下側のほかに、アプリケータ１２上側の、ラムと呼ばれている連結部材等がある。また、ラムをトグル機構で駆動する機種であれば、トグルの支点部に取り付けることもできる。そしてまた、歪センサで歪を検出することにより間接的に圧力を検出する場合、歪センサは、端子圧着装置の駆動部及び台座を覆う筐体の側面等に取り付けることができる。 Therefore, a technology has been developed that detects abnormalities during crimping of terminals by using pressure sensors, strain sensors, etc., identifies crimping conditions, and automatically detects crimping defects. As a mounting location of the pressure sensor, in addition to the lower side of the base plate 11 of the terminal crimping apparatus as shown in FIG. Moreover, if it is a model which drives a ram with a toggle mechanism, it can also be attached to the fulcrum part of a toggle. When the pressure is indirectly detected by detecting the strain with the strain sensor, the strain sensor can be attached to the side surface of the housing that covers the drive unit and the base of the terminal crimping device.
　端子圧着不良検出装置を適用するに当たって、ここでは、一例として、圧力センサ１を、端子圧着装置のベース板１１の下側に設けたものを示しており、その圧力センサ１からリード線２０を引き出す。その圧力センサ１は、端子圧着時に、クリンパー１３，１３から、被覆電線１５，端子１７，アンビル１４，ベース板１１を介して圧力を受け、電圧を出力する。 In applying the terminal crimping failure detection device, here, as an example, the pressure sensor 1 is shown below the base plate 11 of the terminal crimping device, and the lead wire 20 is pulled out from the pressure sensor 1. . The pressure sensor 1 receives pressure from the crimpers 13 and 13 via the covered electric wire 15, the terminal 17, the anvil 14, and the base plate 11 when the terminal is crimped, and outputs a voltage.
　そして、図６に示すように、圧力センサ１の出力電圧をＡ－Ｄ変換器２でデジタル信号に変換した後、圧力管理装置３に入力する。圧力管理装置３では、受け取った圧力センサ１の出力電圧を所定時間間隔でサンプリングして、圧着１回分が十分に含まれるだけのデータを、波形データとして各圧力値を羅列した形で順次記録していく。そして、予め記憶された正常時の基準波形と、検査時に出力された圧力波形とを比較することにより、良品か不良品かを判別して判別信号を出力する。 Then, as shown in FIG. 6, the output voltage of the pressure sensor 1 is converted into a digital signal by the AD converter 2 and then input to the pressure management device 3. In the pressure management device 3, the received output voltage of the pressure sensor 1 is sampled at a predetermined time interval, and data sufficient for one crimping is sufficiently recorded as waveform data in the form of enumerating each pressure value. To go. Then, a normal reference waveform stored in advance and a pressure waveform output at the time of inspection are compared to determine whether the product is a non-defective product or a defective product, and a determination signal is output.
　圧力管理装置３では、そのようにして、圧着１回分の完全な波形データが比較されるため、圧着開始直後の微妙な波形の変化を捉えることができ、絶縁バレルの内折れ，外折れ、アプリケータのキャリア送り不良、キャリアカッタの不良等の検出が可能になる。なお、このような端子圧着不良検出装置に関連する従来文献としては、例えば、特許文献１がある。 In this way, the complete waveform data for one crimping is compared in the pressure management device 3, so that it is possible to capture subtle changes in the waveform immediately after the start of crimping. This makes it possible to detect the carrier feed failure of the printer and the carrier cutter. In addition, there exists patent document 1 as a prior art literature relevant to such a terminal crimping defect detection apparatus, for example.
　従来は、このように端子圧着装置に設けた圧力センサや歪センサにより端子圧着時の圧力波形を取得して、端子の圧着不良を検出するほかに、例えば、特許文献２に示されるように、端子圧着後の被覆電線の搬送経路上に光学的な検査装置を設けて、二重に検査を行って、圧着不良の被覆電線を極力排除できるようにしていた。 Conventionally, in addition to obtaining a pressure waveform at the time of terminal crimping by using a pressure sensor and a strain sensor provided in the terminal crimping device in this way, and detecting a crimp failure of the terminal, for example, as shown in Patent Document 2, An optical inspection device is provided on the transport path of the covered electric wire after the terminal is crimped, and double inspection is performed so that the covered electric wire with poor crimping can be eliminated as much as possible.
　図７は、従来の光学的手段により検査を行う端子圧着不良検出装置の概略構成を示す図である。図７において、４は端子部の静止画像を取得するためのカメラ、５は画像検査装置、６は端子付き電線の通過を検知するための通過センサ、７は端子付き電線の搬送装置、８は端子付き電線である。 FIG. 7 is a diagram showing a schematic configuration of a terminal crimping defect detecting device for inspecting by conventional optical means. In FIG. 7, 4 is a camera for acquiring a still image of the terminal portion, 5 is an image inspection device, 6 is a passage sensor for detecting the passage of the electric wire with terminal, 7 is a conveying device for the electric wire with terminal, and 8 is It is an electric wire with a terminal.
　端子圧着装置で端子の圧着が行われた後、搬送装置７により搬送中の端子付き電線８を、照明装置（図示せず）で照明しながらカメラ４で撮影し、その画像データを画像検査装置５に取り込む。画像検査装置５は、ＣＰＵ（中央演算装置）を備えていて、カメラ４から取り込んだ画像データの処理を実行する。 After the terminal is crimped by the terminal crimping device, the terminal-attached electric wire 8 being conveyed by the conveying device 7 is photographed by the camera 4 while illuminating with an illumination device (not shown), and the image data is image inspection apparatus. 5 The image inspection device 5 includes a CPU (Central Processing Unit), and executes processing of image data captured from the camera 4.
　端子圧着装置で電線端部に端子を圧着した端子付き電線８を搬送装置７で送って、カメラ４の下を通過させる。その時、通過センサ６で端子付き電線８の通過を検知し、所定の遅延時間を与えて、端子付き電線８がカメラ４の下を通過するタイミングでカメラ４のシャッタを切る。 The terminal-attached electric wire 8 whose terminal is crimped to the end of the electric wire by the terminal crimping device is sent by the transport device 7 and passed under the camera 4. At that time, the passage sensor 6 detects the passage of the electric wire 8 with a terminal, gives a predetermined delay time, and releases the shutter of the camera 4 at a timing when the electric wire 8 with a terminal passes under the camera 4.
　そのようにして取得した画像データについて、所定の枠内において、電線を横切る方向に、複数回平行に走査して第１の座標軸を決定し、それと直交する第２の座標軸を決定する。そして、両座標軸を基準として前記画像データの位置を調整し、端子圧着状態の良否判定を行う。このような、画像による検査装置によれば、上記したような端子圧着不良のほかに、バレル表面の傷や異物の有無、被覆電線の被覆の色の検査もできる。 The image data acquired in this manner is scanned in parallel in the direction across the electric wire a plurality of times within a predetermined frame to determine the first coordinate axis, and the second coordinate axis orthogonal to the first coordinate axis is determined. And the position of the said image data is adjusted on the basis of both coordinate axes, and the quality determination of the terminal crimping state is performed. According to such an image inspection apparatus, in addition to the above-described terminal crimping failure, it is possible to inspect the barrel surface for flaws and foreign matter, and the color of the covered wire.
　そして、上記圧力管理装置３による判定結果と、画像検査装置５による判定結果に基づいて圧着不良の検出を行っていたが、いずれか一方が不良と判定すれば、その電線を圧着不良と判断していた。従来は、このようにして、端子圧着装置で被覆電線に圧着した端子の圧着不良の検出を行っていた。 And although the crimping | compression-bonding failure was detected based on the determination result by the said pressure management apparatus 3, and the determination result by the image test | inspection apparatus 5, if any one is determined to be defective, it will determine that the electric wire is a crimping failure. It was. Conventionally, in this way, detection of a crimping failure of a terminal crimped to a covered electric wire by a terminal crimping device has been performed.

　しかしながら、上記従来の端子圧着不良検出装置には、圧力管理装置と、画像検査装置のいずれか一方が不良と判定すれば、その電線を圧着不良と判断していたため、良品を不良品と誤判定してしまうことが多く、製品の廃棄による部材の無駄や、設備停止による生産性の低下が起きるという問題点があった。 However, in the above-described conventional terminal crimping failure detection device, if either the pressure management device or the image inspection device is judged to be defective, the wire is determined to be a crimping failure. In many cases, there are problems such as waste of parts due to the disposal of products and a decrease in productivity due to equipment stoppage.
　一方、従来の端子圧着不良検出装置では、不良品を良品と誤判定してしまうこともあり、それを見逃して不良品が良品の中に混在した状態で出荷すると、それを使用するメーカーに多大な迷惑をかけることになるという問題点もあった。 On the other hand, in the conventional terminal crimping failure detection device, a defective product may be misjudged as a non-defective product. There was also a problem that it would cause trouble.
　本発明は、そのような問題点に鑑み、圧力管理装置の判定結果と、画像検査装置の判定結果とを効果的に組み合わせて、より精度の高い判定を下せるようにし、良品を不良品と判断してしまったり、不良品を良品と判定してしまったりする誤判定を減らすことを目的とするものである。 In view of such a problem, the present invention effectively combines the determination result of the pressure management device and the determination result of the image inspection device so that a more accurate determination can be made, and a non-defective product is determined to be a defective product. The purpose of this is to reduce false determinations such as determining whether a defective product is a non-defective product.

　以下、本発明の実施例を図面に基づいて詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
　図１は、本発明の端子圧着不良検出装置の概略構成図である。符号は、図６，図７のものに対応しており、圧力管理装置３は、図６に示したものと同様に、圧力センサ１の出力を所定時間間隔でサンプリングして取得した波形データを、基準波形と比較して圧着状態の良否を判定する。また、画像検査装置５は、図７に示したものと同様に、端子付き電線の画像データに基づいて、端子圧着状態の良否判定を行う。総合判定装置９は、パソコンにより構成され、それに圧力管理装置３と画像検査装置５を接続し、内蔵するプログラムにより、圧力管理装置３の判定結果と、画像検査装置５の判定結果とを勘案して、より精度の高い判定を下すようにする。 FIG. 1 is a schematic configuration diagram of a terminal crimping defect detecting device according to the present invention. The reference numerals correspond to those in FIGS. 6 and 7, and the pressure management device 3 obtains waveform data obtained by sampling the output of the pressure sensor 1 at predetermined time intervals in the same manner as that shown in FIG. 6. The quality of the crimped state is determined by comparing with the reference waveform. Moreover, the image inspection apparatus 5 performs pass / fail determination of the terminal crimping state based on the image data of the electric wire with terminal, similarly to the one shown in FIG. The comprehensive judgment device 9 is constituted by a personal computer, and the pressure management device 3 and the image inspection device 5 are connected to it, and the judgment result of the pressure management device 3 and the judgment result of the image inspection device 5 are taken into account by a built-in program. To make a more accurate determination.
　また、総合判定装置９は、図５に示した端子圧着装置や、図７に示した端子付き電線８搬送装置７等の加工設備を総合的に制御するための制御装置に判定結果を出力する。なお、総合判定装置９として、パソコンの代わりに、ＰＬＣ等、プログラムで動作するその他の制御装置を用いてもよい。 The comprehensive determination device 9 outputs the determination result to a control device for comprehensively controlling processing equipment such as the terminal crimping device shown in FIG. 5 and the terminal-equipped electric wire 8 conveying device 7 shown in FIG. . In addition, as the comprehensive determination apparatus 9, you may use the other control apparatus which operate | moves by a program, such as PLC, instead of a personal computer.
　圧力管理装置３及び画像検査装置５は、端子圧着装置で１回の圧着作業が行われる度毎に、良否の判定結果を総合判定装置に送り、画像検査装置５は、さらに、判定に用いた画像データも総合判定装置に送る。 The pressure management device 3 and the image inspection device 5 send a pass / fail judgment result to the comprehensive judgment device every time one crimping operation is performed by the terminal crimping device, and the image inspection device 5 is further used for the judgment. The image data is also sent to the comprehensive judgment device.
　図２は、第１実施例の処理を示すフローチャートである。この処理は、総合判定装置で実行され、同一の端子付き電線について、圧力管理装置３と画像検査装置５から判定結果が送られてくる度毎に開始される。タイミング的には、圧力管理装置３から判定結果が送られてきた後、端子付き電線８がカメラ４の位置まで搬送されるまでの時間が遅れて画像検査装置５から判定結果が送られてくるので、総合判定装置９は、圧力管理装置３からの情報を保持しておき、画像検査装置５から判定結果が送られてきてから処理は開始される。 FIG. 2 is a flowchart showing the processing of the first embodiment. This process is executed by the comprehensive determination device and is started each time determination results are sent from the pressure management device 3 and the image inspection device 5 for the same electric wire with terminal. In terms of timing, after the determination result is sent from the pressure management device 3, the determination result is sent from the image inspection device 5 with a delay until the wire 8 with terminal 8 is conveyed to the position of the camera 4. Therefore, the comprehensive determination device 9 holds the information from the pressure management device 3 and the processing is started after the determination result is sent from the image inspection device 5.
　まず、圧力管理装置３と画像検査装置５から判定結果が送られてきたら、それを取得する（ステップＳ１）。次に、画像検査装置５から受け取った画像データをチェックして、ピントが合っているか、明るさが適正か等、判定画像として適切であるか否かを判別する（ステップＳ２）。 First, when determination results are sent from the pressure management device 3 and the image inspection device 5, they are acquired (step S1). Next, the image data received from the image inspection apparatus 5 is checked to determine whether it is appropriate as a determination image, such as whether it is in focus or brightness is appropriate (step S2).
　ステップＳ２で、判定画像として適切であったら、画像検査装置５の判定の信頼性は高いので、総合判定結果として、画像検査装置５の判定結果を採用する（ステップＳ３）。一方、ステップＳ２で、判定画像として適切でなかったら、画像検査装置５の判定は信頼できないので、総合判定結果として、圧力管理装置３の判定結果を採用する（ステップＳ４）。そして、総合判定結果を、端子圧着装置の制御部に出力し（ステップＳ5）、次の判定に備える。 If it is appropriate as the determination image in step S2, the determination result of the image inspection apparatus 5 is adopted as the comprehensive determination result because the determination reliability of the image inspection apparatus 5 is high (step S3). On the other hand, if the determination image is not appropriate in step S2, the determination of the image inspection apparatus 5 is not reliable, and therefore the determination result of the pressure management apparatus 3 is adopted as the comprehensive determination result (step S4). Then, the comprehensive determination result is output to the control unit of the terminal crimping apparatus (step S5) to prepare for the next determination.
　このようにすれば、判定画像が適切でなかったことによる画像検査装置５の誤判定を防止して、その分、製品の廃棄による部材の無駄や、設備停止による生産性の低下を低減できる。 In this way, it is possible to prevent erroneous determination of the image inspection apparatus 5 due to an inappropriate determination image, and accordingly, it is possible to reduce the waste of members due to product disposal and the decrease in productivity due to equipment stoppage.
　図３は、第２実施例の処理を示すフローチャートである。この実施例では、圧力管理装置３は、総合判定装置９に対して、検査項目毎の判定結果も送信し、画像検査装置５は、判定に用いた画像データ及び判定結果に加えて検査項目毎の判定結果も送信する。そして、総合判定装置９は、圧力管理装置３と画像検査装置５からそれらの情報が送られてくる度毎に開始される。 FIG. 3 is a flowchart showing the processing of the second embodiment. In this embodiment, the pressure management device 3 also transmits a determination result for each inspection item to the comprehensive determination device 9, and the image inspection device 5 adds the image data and the determination result used for the determination for each inspection item. The determination result is also transmitted. The comprehensive determination device 9 is started each time information is sent from the pressure management device 3 and the image inspection device 5.
　まず、圧力管理装置３と画像検査装置５から上記情報が送られてきたら、それを取得する（ステップＳ１１）。次に、画像検査装置５から受け取った画像データをチェックして、ピントが合っているか、明るさが適正か等、判定画像として適切であるか否かを判別し（ステップＳ１２）、判定画像として適切であれば、総合判定結果として、画像検査装置５の判定結果を採用する（ステップＳ１３）。 First, when the above information is sent from the pressure management device 3 and the image inspection device 5, it is acquired (step S11). Next, the image data received from the image inspection apparatus 5 is checked to determine whether it is appropriate as a determination image, such as whether the image is in focus or brightness (step S12). If appropriate, the determination result of the image inspection apparatus 5 is adopted as the comprehensive determination result (step S13).
　ステップＳ１２で、受け取った画像データが、ピント，明るさ等が適正範囲から外れていて、判定画像として適切でなければ、浅打ち、深打ち、絶縁バレルの内折れ，外折れ、芯線こぼれ、被覆電線の色等の検査項目毎に以下の処理を順次繰り返す（ステップＳ１４）。まず、その検査項目は、画像データが不適切であることの影響を受けるか否かを判別する（ステップＳ１５）。例えば、画像データがピンボケだったとき、検査項目が被覆電線の色であれば、画像データがピンボケでも正しく判定できるが、検査項目が、浅打ち、深打ち、絶縁バレルの内折れ，外折れ等の場合は、画像データがピンボケであると正しい判定はできない。 In step S12, if the received image data is out of the proper range for focus, brightness, etc. and is not suitable as a judgment image, shallow strike, deep strike, inner barrel breakage, outer breakage, core spillage, covering The following processing is sequentially repeated for each inspection item such as the color of the electric wire (step S14). First, it is determined whether or not the inspection item is affected by improper image data (step S15). For example, when the image data is out of focus, if the inspection item is the color of the covered wire, the image data can be correctly determined even if out of focus, but the inspection item is shallow, deep, insulation barrel folds, external folds, etc. In the case of, correct determination cannot be made if the image data is out of focus.
　ステップＳ１５で、影響を受けなければ、その判定項目についての画像検査装置５の判定結果は「不良」であるか否かを判別し（ステップＳ１６）、「不良」でなければ、次の検査項目に移り、「不良」であれば、総合判定を「不良」とする（ステップＳ１８）。 If it is not influenced in step S15, it is determined whether or not the determination result of the image inspection apparatus 5 for the determination item is “defective” (step S16). If it is “defective”, the overall determination is “defective” (step S18).
　ステップ１５で、影響を受けると判断されれば、その検査項目についての画像検査装置５の判定は信頼できないので圧力管理装置３の判定結果を参照して、その検査項目についての圧力管理装置３の判定結果は「不良」であるか否かを判別し（ステップＳ１７）、「不良」でなければ、次の検査項目に移り、「不良」であれば、総合判定を「不良」する（ステップＳ１８）。 If it is determined in step 15 that the inspection is affected, the determination of the image inspection apparatus 5 for the inspection item is not reliable, so the determination result of the pressure management apparatus 3 is referred to and the pressure management apparatus 3 for the inspection item is referred to. It is determined whether or not the determination result is “defective” (step S17). If it is not “defective”, the process proceeds to the next inspection item, and if it is “defective”, the overall determination is “failed” (step S18). ).
　すべての検査項目についてステップＳ１５～ステップＳ１８の処理が終了し、「不良」とならなかったら、総合判定を「良」とする（ステップＳ１９）。 If the processing of step S15 to step S18 is completed for all the inspection items and does not become “defective”, the overall determination is “good” (step S19).
　最後に、端子圧着装置の制御部に総合判定結果を出力し（ステップＳ２０）、次の判定に備える。 Finally, the comprehensive determination result is output to the control unit of the terminal crimping device (step S20) to prepare for the next determination.
　このようにすれば、判定画像が適切でなかったことによる画像検査装置５の誤判定を防止して、その分、製品の廃棄による部材の無駄や、設備停止による生産性の低下を低減できる。しかも、画像データが不適切であった場合も、その影響を受けない検査項目については、より精度の高い検査が期待できる画像検査装置５の判定結果を採用できる。 In this way, it is possible to prevent erroneous determination of the image inspection apparatus 5 due to an inappropriate determination image, and accordingly, it is possible to reduce the waste of members due to product disposal and the decrease in productivity due to equipment stoppage. Moreover, even when the image data is inappropriate, the determination result of the image inspection apparatus 5 that can expect a more accurate inspection can be adopted for the inspection items that are not affected by the image data.
　図４は、第３実施例の処理を示すフローチャートである。端子付き電線の端子圧着不良の内、「芯線切れ」や「圧着高さ異常」は画像には現れにくく、画像による検出よりも圧力波形に基づく検出の方が信頼度が高い。そこで、この実施例では、「芯線切れ」や「圧着高さ異常」の電線を先に排除するため、圧力波形による検査を先行させるようにした。 FIG. 4 is a flowchart showing the process of the third embodiment. Of the terminal crimping defects of the terminal-attached electric wires, “cut core wire” and “crimp height abnormality” are less likely to appear in the image, and the detection based on the pressure waveform is more reliable than the detection based on the image. Therefore, in this example, in order to eliminate the “core wire breakage” or “crimp height abnormality” wires first, the inspection using the pressure waveform was preceded.
　圧力管理装置３は、総合判定装置９に対して、基準値と比較して端子圧着の良否を判定するための、波形データの所定領域の面積値等、波形データに基づいて算出した圧力波形の特徴を表す数値を送信し、画像検査装置５は、判定に用いた画像データ及び検査項目毎の判定結果を送信する。そして、総合判定装置９は、圧力管理装置３と画像検査装置５からそれらの情報が送られてきたときに開始される。 The pressure management device 3 compares the pressure waveform calculated based on the waveform data, such as the area value of a predetermined region of the waveform data, for determining whether the terminal crimping is good or bad with respect to the overall determination device 9. The numerical value representing the feature is transmitted, and the image inspection apparatus 5 transmits the image data used for the determination and the determination result for each inspection item. The comprehensive determination device 9 is started when the information is sent from the pressure management device 3 and the image inspection device 5.
　まず、圧力管理装置３と画像検査装置５から上記情報が送られてきたら、それを取得する（ステップＳ２１）。次に、圧力管理装置３から受け取った上記圧力波形の特徴を表す数値を、通常の判定公差と比較して良否の判定を行い（ステップＳ２２）、判定結果が「不良」であるか否かを判別する（ステップＳ２３）。その結果、不良判定であったら、総合判定を「不良」とする（ステップＳ２４）。 First, when the above information is sent from the pressure management device 3 and the image inspection device 5, it is acquired (step S21). Next, the numerical value representing the characteristic of the pressure waveform received from the pressure management device 3 is compared with a normal determination tolerance to determine whether it is good or bad (step S22), and whether or not the determination result is “bad”. It discriminate | determines (step S23). As a result, if it is a failure determination, the overall determination is “failed” (step S24).
　ステップＳ２３で、判定が「不良」ではなかったら、画像検査装置５から受け取った画像データをチェックして、ピントが合っているか、明るさが適正か等、判定画像として適切であるか否かを判別し（ステップＳ２５）、判定画像として適切であれば、総合判定結果として、画像検査装置５の判定結果を採用する（ステップＳ２６）。 In step S23, if the determination is not “bad”, the image data received from the image inspection apparatus 5 is checked to determine whether the determination image is appropriate, such as whether the image is in focus or brightness is appropriate. If it is determined (step S25) and it is appropriate as the determination image, the determination result of the image inspection apparatus 5 is adopted as the comprehensive determination result (step S26).
　ステップＳ２５で、判定画像として適切ではなかったら、浅打ち、深打ち、絶縁バレルの内折れ，外折れ、芯線こぼれ、被覆電線の色等の検査項目毎に以下の処理を順次繰り返す（ステップＳ２７）。まず、その検査項目は、画像データが不適切であることの影響を受けるか否かを判別する（ステップＳ２８）。例えば、画像データがピンボケだったとき、検査項目が被覆電線の色であれば、画像データがピンボケでも正しく判定できるが、検査項目が、浅打ち、深打ち、絶縁バレルの内折れ，外折れ等の場合は、画像データがピンボケであると正しい判定はできない。 If it is not appropriate as the determination image in step S25, the following processing is sequentially repeated for each inspection item such as shallow hitting, deep hitting, inner fold, outer fold, core spill, and coated wire color (step S27). . First, it is determined whether or not the inspection item is affected by improper image data (step S28). For example, when the image data is out of focus, if the inspection item is the color of the covered wire, the image data can be correctly determined even if out of focus, but the inspection item is shallow, deep, insulation barrel folds, external folds, etc. In the case of, correct determination cannot be made if the image data is out of focus.
　ステップＳ２８で、画像データが不適切であることの影響を受けなければ、その判定項目についての画像検査装置５の判定結果は「不良」であるか否かを判別し（ステップＳ３１）、「不良」でなければ、次の検査項目に移り、「不良」であれば、総合判定を「不良」とする（ステップＳ３２）。 In step S28, if the image data is not affected by inappropriateness, it is determined whether or not the determination result of the image inspection apparatus 5 for the determination item is “defective” (step S31). If not, the process proceeds to the next inspection item, and if it is “defective”, the overall determination is “defective” (step S32).
　ステップＳ２８で、画像データが不適切であることの影響を受ければ、圧力管理装置３から受け取った上記圧力波形の特徴を表す数値を、通常の判定公差より厳しい判定公差と比較して良否の判定を行い（ステップＳ２９）、判定結果が「不良」であるか否かを判別する（ステップＳ３０）。その結果、「不良」でなければ次の検査項目に移り、「不良」であれば、総合判定を「不良」とする（ステップＳ３２）。 In step S28, if the image data is affected by improperness, the numerical value representing the characteristic of the pressure waveform received from the pressure management device 3 is compared with a determination tolerance that is stricter than a normal determination tolerance. (Step S29), and it is determined whether or not the determination result is “bad” (step S30). As a result, if it is not “defective”, the process proceeds to the next inspection item, and if it is “defective”, the overall determination is “defective” (step S32).
　すべての検査項目についてステップＳ２８～ステップＳ３１の処理が終了し、「不良」とならなかったら、総合判定を「良」とする（ステップＳ３３）。 If the processing from step S28 to step S31 is completed for all the inspection items and does not become “defective”, the overall determination is “good” (step S33).
　最後に、端子圧着装置の制御部に総合判定結果を出力し（ステップＳ３４）、次の判定に備える。 Finally, the comprehensive determination result is output to the control unit of the terminal crimping device (step S34) to prepare for the next determination.
　このようにすれば、判定公差の関係で、本来不良品と判定をすべき端子付き電線を良品であるとする誤判定を防止することができる。 In this way, it is possible to prevent an erroneous determination that a terminal-equipped wire that should be determined as a defective product is a non-defective product due to a determination tolerance.
　なお、上記実施例における圧力管理装置３では、端子圧着装置のベース板の下側に設けた圧力センサ１の出力に基づいて端子圧着不良を検出する場合で説明したが、それに限定されず、ラムやトグルの支点に設けた圧力センサの出力や、端子圧着装置の筐体に取り付けた歪センサの出力に基づいて端子圧着不良を検出する場合にも適用可能である。 In the pressure management device 3 in the above embodiment, the terminal crimping failure is detected based on the output of the pressure sensor 1 provided on the lower side of the base plate of the terminal crimping device.
