Description

圧着端子の圧着状態検査装置Crimp condition inspection device for crimp terminals
　本発明は、電線に圧着された端子の圧着状態を検査する圧着端子の圧着状態検査装置に関する。 The present invention relates to a crimping state inspection device for a crimping terminal that inspects the crimping state of a terminal crimped to an electric wire.
　従来から、ワイヤハーネス等として、端子が圧着された電線がよく利用されている。ワイヤハーネスは、例えば、電線処理装置によって自動的に製造される。電線処理装置では、電線の切断、被覆の剥ぎ取り、端子の圧着が順に行われ、端子付きの電線が連続的に製造される。端子の圧着状態が良好でない電線は不良品となる。ワイヤハーネスの製造過程においては、不良品の発生を迅速且つ正確に把握することが望まれる。 Conventionally, electric wires with crimped terminals are often used as wire harnesses. For example, the wire harness is automatically manufactured by an electric wire processing apparatus. In the electric wire processing apparatus, cutting of the electric wire, peeling of the coating, and crimping of the terminal are sequentially performed, and the electric wire with the terminal is continuously manufactured. An electric wire with poor terminal crimping is a defective product. In the manufacturing process of the wire harness, it is desired to quickly and accurately grasp the occurrence of defective products.
　従来から、カメラ等の撮像装置を利用して端子の圧着状態を検査する装置が知られている（例えば、特許文献１および２参照）。特許文献１には、電線の搬送中に、電線の長手方向および端子の移動方向と直交する方向から、端子をテレビカメラで撮像する装置が記載されている。特許文献２には、圧着された端子を正面から撮像する装置が記載されている。 2. Description of the Related Art Conventionally, an apparatus for inspecting a crimped state of a terminal using an imaging apparatus such as a camera is known (see, for example, Patent Documents 1 and 2). Patent Document 1 describes an apparatus that images a terminal with a television camera from the direction orthogonal to the longitudinal direction of the electric wire and the moving direction of the terminal during conveyance of the electric wire. Patent Document 2 describes an apparatus that images a crimped terminal from the front.

　端子の移動方向と直交する方向から端子を撮像する場合、あるいは端子の正面から端子を撮像する場合、カメラは端子の移動経路から外れた位置に設置される。そのため、電線の搬送中に、移動する端子とカメラとが干渉するおそれはない。 When the terminal is imaged from the direction orthogonal to the terminal moving direction, or when the terminal is imaged from the front of the terminal, the camera is installed at a position off the terminal moving path. Therefore, there is no possibility that the moving terminal and the camera interfere with each other during conveyance of the electric wire.
　近年、電線の細径化や端子の小型化が進み、より精密に端子の圧着状態を検査することが望まれている。端子の移動方向の前側部分または後側部分を撮像できれば、従来は検出することが難しかった不良状態を検出することが可能になる。また、従来よりも高度な検査が可能となる。しかし、端子の移動方向の前側部分または後側部分を撮像しようとして端子の移動経路上にカメラを設置することとすると、端子とカメラとが干渉してしまう。 In recent years, the diameter of electric wires and the size of terminals have been reduced, and it is desired to inspect the crimped state of terminals more precisely. If the front part or the rear part in the moving direction of the terminal can be imaged, it becomes possible to detect a defective state that has been difficult to detect in the past. In addition, a higher level of inspection than before can be performed. However, if a camera is installed on the movement path of the terminal in an attempt to image the front part or the rear part in the terminal movement direction, the terminal and the camera interfere with each other.
　本発明はかかる点に鑑みてなされたものであり、その目的とするところは、電線を搬送している際に端子の移動方向の前側部分または後側部分を撮像することができる圧着端子の圧着状態検査装置を提供することにある。 This invention is made | formed in view of this point, The place made into the objective is crimping | crimping of the crimp terminal which can image the front side part or rear side part of the moving direction of a terminal, when conveying an electric wire. It is to provide a state inspection device.
　本発明に係る圧着端子の圧着状態検査装置は、端子が圧着された電線を保持する保持機構と、前記電線の長手方向と交差する方向に前記保持機構を移動させる移動機構と、前記端子の移動経路から離れた位置に配置された撮像装置と、前記保持機構の移動中に、前記端子の移動方向の前側部分または後側部分が前記撮像装置と正対するように、前記保持機構を駆動することによって前記電線を回転させる駆動機構と、を備えたものである。 A crimping state inspection device for a crimping terminal according to the present invention includes a holding mechanism for holding an electric wire with a terminal crimped thereon, a moving mechanism for moving the holding mechanism in a direction intersecting with a longitudinal direction of the electric wire, and movement of the terminal Driving the holding mechanism such that the front part or the rear part of the moving direction of the terminal faces the imaging apparatus during movement of the imaging apparatus disposed at a position away from the path and the holding mechanism; And a drive mechanism for rotating the electric wire.
　なお、ここで言うところの「交差」には、垂直に交差する場合と斜めに交差する場合との両方が含まれる。「電線の回転」には、電線を当該電線の中心周りに回転させる場合（いわゆる自転）の他、電線を旋回等させることにより電線の位置および姿勢を変化させる場合（いわゆる公転等）も含まれる。「保持機構の移動中」には、保持機構の所定方向への移動を継続させたまま電線を回転させる場合と、保持機構の所定方向への移動を一時的に停止して電線を回転させる場合との両方が含まれる。 It should be noted that the term “intersection” here includes both the case of intersecting vertically and the case of intersecting diagonally. “Rotation of electric wire” includes not only the case where the electric wire is rotated around the center of the electric wire (so-called rotation) but also the case where the position and posture of the electric wire is changed by turning the electric wire (so-called revolution). . When the holding mechanism is moving, when the electric wire is rotated while the holding mechanism continues to move in the predetermined direction, or when the electric wire is rotated while temporarily stopping the movement of the holding mechanism in the predetermined direction And both.
　上記検査装置によれば、駆動装置が保持機構を駆動することにより、電線が回転させられる。それに伴って端子も回転し、端子の移動方向の前側部分または後側部分は、撮像装置と正対する。よって、端子の移動経路から離れた位置に配置された撮像装置によって、端子の前側部分または後側部分を撮像することができる。したがって、端子が移動している際に、端子の前側部分または後側部分を撮像することが可能となる。 According to the inspection apparatus, the electric wire is rotated by driving the holding mechanism by the driving device. Accordingly, the terminal also rotates, and the front part or the rear part in the moving direction of the terminal faces the imaging apparatus. Therefore, the front part or the rear part of the terminal can be imaged by the imaging device arranged at a position away from the movement path of the terminal. Therefore, when the terminal is moving, it is possible to image the front part or the rear part of the terminal.
　前記駆動機構は、前記保持機構を回転させる機構であってもよい。なお、ここでの「回転」にも、いわゆる自転および公転の両方が含まれる。 The drive mechanism may be a mechanism that rotates the holding mechanism. The “rotation” here includes both so-called rotation and revolution.
　前記保持機構は、前記電線を狭持する一対の狭持部材を有し、前記駆動機構は、前記電線を狭持したまま一方の狭持部材が他方の狭持部材に対して相対的にスライドすることによって前記電線を回転させるように、一方または両方の狭持部材をスライドさせる機構であってもよい。 The holding mechanism has a pair of holding members that hold the electric wire, and the driving mechanism is configured such that one holding member slides relative to the other holding member while holding the electric wire. By doing so, a mechanism for sliding one or both of the holding members so as to rotate the electric wire may be used.
　このことにより、電線を迅速に回転させることができる。また、電線の回転に要する電力を削減することができる。 This makes it possible to rotate the electric wire quickly. Moreover, the electric power required for the rotation of the electric wire can be reduced.
　前記撮像装置は、前記端子の移動方向と直交する方向を向くように設置され、前記駆動機構は、前記電線を９０度回転させるように前記保持機構を駆動するものであってもよい。 The imaging device may be installed so as to face a direction orthogonal to the moving direction of the terminal, and the driving mechanism may drive the holding mechanism so as to rotate the electric wire by 90 degrees.
　前記撮像装置は、前記電線の回転前および回転後の前記端子の画像を撮像するように構成され、前記検査装置は更に、前記電線の回転前および回転後の前記端子の撮像画像に基づいて、前記端子の圧着状態の良否判定を行う良否判定装置を備えていてもよい。 The imaging device is configured to capture an image of the terminal before and after rotation of the electric wire, and the inspection device is further based on the captured image of the terminal before and after rotation of the electric wire, You may provide the quality determination apparatus which performs the quality determination of the crimping state of the said terminal.
　このことにより、端子に関する２方向からの撮像画像を得ることができ、より高度な良否判定が可能となる。加えて、上記２方向からの撮像画像を、単一の撮像装置により得ることができる。 This makes it possible to obtain captured images from two directions related to the terminal, and to make a higher quality pass / fail judgment. In addition, the captured images from the two directions can be obtained by a single imaging device.
　前記撮像装置は、前記端子の移動方向と斜めに交差する方向を向くように設置され、前記駆動機構は、前記電線を９０度未満の所定角度回転させるように前記保持機構を駆動するものであってもよい。 The imaging device is installed so as to face a direction obliquely intersecting the moving direction of the terminal, and the drive mechanism drives the holding mechanism to rotate the electric wire by a predetermined angle of less than 90 degrees. May be.
　このことにより、電線の回転角度が９０度よりも小さいので、端子の前側部分または後側部分を撮像装置に正対させるまでの時間を短縮することができる。また、より少ない消費電力によって、端子の前側部分または後側部分を撮像装置に正対させることができる。 Thereby, since the rotation angle of the electric wire is smaller than 90 degrees, it is possible to shorten the time until the front part or the rear part of the terminal is directly opposed to the imaging apparatus. In addition, the front part or the rear part of the terminal can be directly opposed to the imaging device with less power consumption.
　本発明によれば、電線を搬送している際に端子の移動方向の前側部分または後側部分を撮像することができる圧着端子の圧着状態検査装置を得ることができる。 According to the present invention, it is possible to obtain a crimping state inspection device for a crimping terminal capable of imaging the front side portion or the rear side portion of the terminal in the moving direction when the electric wire is being conveyed.

　＜実施形態１＞
　本実施形態に係る圧着端子の圧着状態検査装置（以下、単に検査装置という）は、ワイヤハーネスを製造する電線処理装置１に内蔵されたものである。図１は、電線処理装置１の全体構成を模式的に示す平面図である。電線処理装置１は、フロント側およびリア側のクランプ１１，１２と、フロント側およびリア側の搬送ユニット１３，１４と、フロント側およびリア側の端子圧着ユニット１７，１８と、カッターユニット９と、排出トレイ５と、コンピュータ２と、表示装置３とを備えている。 <Embodiment 1>
The crimp terminal crimping state inspection apparatus (hereinafter simply referred to as an inspection apparatus) according to the present embodiment is built in the wire processing apparatus 1 that manufactures a wire harness. FIG. 1 is a plan view schematically showing the overall configuration of the electric wire processing apparatus 1. The electric wire processing apparatus 1 includes front and rear clamps 11 and 12, front and rear transport units 13 and 14, front and rear terminal crimping units 17 and 18, a cutter unit 9, A discharge tray 5, a computer 2, and a display device 3 are provided.
　クランプ１１，１２は、被覆された電線（以下、単に電線という）１０を保持するものである。クランプ１１，１２の構成は何ら限定されず、従来から公知の各種クランプを用いることができる。フロント側のクランプ１１とリア側のクランプ１２とは、同一の構成を有している。以下の説明では、リア側のクランプ１２のみを説明し、フロント側のクランプ１１の説明は省略する。図３に示すように、クランプ１２は、電線１０を左右から狭持する一対の爪３１を有している。クランプ１２は、Ｌ字型のアーム３２を介してスライダ３３に連結されている。クランプ１２、アーム３２、およびスライダ３３は、電線１０を保持する保持機構３０を構成している。図示は省略するが、フロント側のクランプ１１も、Ｌ字型のアームを介してスライダに連結されている。 The clamps 11 and 12 hold the covered electric wires (hereinafter simply referred to as electric wires) 10. The configurations of the clamps 11 and 12 are not limited at all, and various conventionally known clamps can be used. The front-side clamp 11 and the rear-side clamp 12 have the same configuration. In the following description, only the rear side clamp 12 will be described, and description of the front side clamp 11 will be omitted. As shown in FIG. 3, the clamp 12 has a pair of claws 31 that hold the electric wire 10 from the left and right. The clamp 12 is connected to a slider 33 via an L-shaped arm 32. The clamp 12, the arm 32, and the slider 33 constitute a holding mechanism 30 that holds the electric wire 10. Although not shown, the front-side clamp 11 is also connected to the slider via an L-shaped arm.
　搬送ユニット１３，１４は、保持機構３０を左右に移動させる移動機構を構成している。搬送ユニット１３，１４にも、従来から公知の各種搬送ユニットを用いることができる。搬送ユニット１３，１４として、例えば、スライダ３３（図３参照）を左方および右方に案内するレールと、スライダ３３を左方および右方に駆動するモータとを用いることができる。 The transport units 13 and 14 constitute a moving mechanism that moves the holding mechanism 30 left and right. Conventionally known various transport units can also be used for the transport units 13 and 14. As the transport units 13 and 14, for example, a rail that guides the slider 33 (see FIG. 3) to the left and right, and a motor that drives the slider 33 to the left and right can be used.
　カッターユニット９は、電線１０の切断と、被覆の剥ぎ取りとを行うものである。カッターユニット９にも、従来から公知の各種カッターユニットを用いることができる。例えば、カッターユニット９は、上下一対のカッター刃と、それらカッター刃を上下に移動させるモータとを有している。 The cutter unit 9 is for cutting the electric wire 10 and stripping the coating. Various conventionally known cutter units can also be used for the cutter unit 9. For example, the cutter unit 9 has a pair of upper and lower cutter blades and a motor that moves the cutter blades up and down.
　端子圧着ユニット１７，１８は、被覆が剥ぎ取られて芯線が露出した電線１０の先端部に、端子１５を圧着するものである。端子圧着ユニット１７，１８にも、従来から公知の各種の端子圧着ユニットを用いることができる。本実施形態では、端子圧着ユニット１７，１８は、電線１０の芯線および被覆の一部を端子１５に重ね合わせた状態で、それらを上方からプレスすることによって端子１５を圧着するものである。 The terminal crimping units 17 and 18 are for crimping the terminal 15 to the distal end portion of the electric wire 10 where the coating is stripped and the core wire is exposed. Various conventionally known terminal crimping units can also be used for the terminal crimping units 17 and 18. In the present embodiment, the terminal crimping units 17 and 18 are for crimping the terminal 15 by pressing them from above in a state where a part of the core wire and the coating of the electric wire 10 are overlapped with the terminal 15.
　平面視において、端子圧着ユニット１７の右方には、撮像装置としてのカメラ２１が設けられている。また、平面視において、端子圧着ユニット１８の左方にも、撮像装置としてのカメラ２２が設けられている。図３に示すように、カメラ２２は下方を向くように配置され、端子１５の圧着状態を上方から撮像する。カメラ２２は端子１５と接触しないように、端子１５の移動経路２５から上方に離れた位置に設置されている。なお、カメラ２２は移動経路２５から下方に離れた位置に設置され、端子１５の下面を撮像するように構成されていてもよい。図示は省略するが、フロント側のカメラ２１もリア側のカメラ２２と同様に配置されている。カメラ２１，２２の種類は特に限定されず、例えば、ＣＣＤカメラ等を用いることができる。 In a plan view, a camera 21 as an imaging device is provided to the right of the terminal crimping unit 17. In addition, a camera 22 as an imaging device is provided on the left side of the terminal crimping unit 18 in plan view. As shown in FIG. 3, the camera 22 is arranged so as to face downward, and images the crimped state of the terminal 15 from above. The camera 22 is installed at a position away from the moving path 25 of the terminal 15 so as not to contact the terminal 15. Note that the camera 22 may be installed at a position away from the movement path 25 and image the lower surface of the terminal 15. Although not shown, the front-side camera 21 is also arranged in the same manner as the rear-side camera 22. The types of the cameras 21 and 22 are not particularly limited, and for example, a CCD camera or the like can be used.
　スライダ３３は、電線１０の長手方向と平行な水平軸周りに回転可能に構成されている（図５（ｂ）および（ｃ）参照）。スライダ３３を回転させる機構は何ら限定されないが、本実施形態では、スライダ３３を回転させるモータ３４が設けられている。モータ３４は、スライダ３３と一体となって左方および右方に移動可能に構成されている。本実施形態では、スライダ３３はモータ３４の駆動力を受けて自転する。ただし、スライダ３３は、旋回（公転）するように構成されていてもよい。図示は省略するが、スライダ３３を案内するレールの一部が、スライダ３３を旋回させるように形成されていてもよい。この場合、モータ３４は必ずしも必要ではなく、スライダ３３を左右に移動させるモータ等が、スライダ３３を回転させる機構としての役割を果たす。本実施形態では、スライダ３３は９０度回転するように構成されている。 The slider 33 is configured to be rotatable around a horizontal axis parallel to the longitudinal direction of the electric wire 10 (see FIGS. 5B and 5C). The mechanism for rotating the slider 33 is not limited in any way, but in the present embodiment, a motor 34 for rotating the slider 33 is provided. The motor 34 is configured to be movable leftward and rightward integrally with the slider 33. In the present embodiment, the slider 33 rotates by receiving the driving force of the motor 34. However, the slider 33 may be configured to turn (revolve). Although illustration is omitted, a part of the rail for guiding the slider 33 may be formed so as to turn the slider 33. In this case, the motor 34 is not necessarily required, and a motor or the like that moves the slider 33 to the left and right serves as a mechanism for rotating the slider 33. In the present embodiment, the slider 33 is configured to rotate 90 degrees.
　次に、検査装置による検査を含めた電線処理装置１の動作を説明する。始めに、電線１０がその長手方向（図１の下方向。矢印参照）に沿って電線処理装置１へ供給される。所定長さの電線１０が供給されると、カッターユニット９によって電線１０の切断および剥ぎ取りが行われる。その後、スライダ３３が駆動され、フロント側のクランプ１１が右方に移動すると共に、リア側のクランプ１２が左方に移動する。被覆が剥ぎ取られた両電線１０は、端子圧着ユニット１７，１８の手前の位置まで搬送される。そして、端子圧着ユニット１７，１８によって、電線１０に端子１５が圧着される（図５（ａ）参照）。 Next, the operation of the wire processing apparatus 1 including the inspection by the inspection apparatus will be described. First, the electric wire 10 is supplied to the electric wire processing apparatus 1 along the longitudinal direction (downward direction of FIG. 1, see arrow). When the electric wire 10 having a predetermined length is supplied, the cutter unit 9 cuts and strips the electric wire 10. Thereafter, the slider 33 is driven, and the front-side clamp 11 moves to the right, and the rear-side clamp 12 moves to the left. The two electric wires 10 from which the coating has been peeled off are conveyed to positions before the terminal crimping units 17 and 18. And the terminal 15 is crimped | bonded to the electric wire 10 by the terminal crimping units 17 and 18 (refer Fig.5 (a)).
　その後、端子１５がカメラ２１，２２の下方の位置に至るまで、クランプ１１，１２が移動する。すなわち、フロント側のクランプ１１は右方に移動し、リア側のクランプ１２は左方に移動する。そして、カメラ２１，２２が端子１５の上面を撮像する（図４参照）。撮像は、クランプ１１，１２を一時停止させて行ってもよく、クランプ１１，１２を一時停止させることなく行ってもよい。なお、図６（ａ）は、端子１５および電線１０の上面を示す図である。撮像された画像は、コンピュータ２に送られる。 Thereafter, the clamps 11 and 12 move until the terminal 15 reaches a position below the cameras 21 and 22. That is, the front-side clamp 11 moves to the right, and the rear-side clamp 12 moves to the left. Then, the cameras 21 and 22 image the upper surface of the terminal 15 (see FIG. 4). Imaging may be performed by temporarily stopping the clamps 11 and 12 or may be performed without temporarily stopping the clamps 11 and 12. FIG. 6A is a view showing the upper surfaces of the terminal 15 and the electric wire 10. The captured image is sent to the computer 2.
　次に、図５（ｂ）に示すように、スライダ３３が移動すると共に９０度回転する。その結果、図５（ｃ）に示すように、クランプ１１，１２に狭持された電線１０は９０度回転すると共に、端子１５が９０度回転した状態でカメラ２１，２２の下方に位置付けられる。そして、カメラ２１，２２は、端子１５の側面を撮像する。なお、図６（ｂ）は、端子１５および電線１０の側面を示す図である。撮像された画像は、コンピュータ２に送られる。 Next, as shown in FIG. 5B, the slider 33 moves and rotates 90 degrees. As a result, as shown in FIG. 5C, the electric wire 10 held between the clamps 11 and 12 is rotated 90 degrees, and the terminal 15 is positioned below the cameras 21 and 22 while being rotated 90 degrees. The cameras 21 and 22 image the side surface of the terminal 15. FIG. 6B is a diagram illustrating the side surfaces of the terminal 15 and the electric wire 10. The captured image is sent to the computer 2.
　コンピュータ２の表示装置３には、例えば、端子１５および電線１０の上面および側面の画像が表示される。ユーザは、それらの画像を観察し、端子１５の圧着状態を検査することができる。また、それらの画像を基にして、画像処理技術を利用して圧着状態の良否判定を自動的に行うことも可能である。この際、コンピュータ２は、圧着状態の良否判定を行う良否判定装置として機能する。 On the display device 3 of the computer 2, for example, images of the upper surface and side surfaces of the terminal 15 and the electric wire 10 are displayed. The user can observe these images and inspect the crimped state of the terminal 15. Moreover, it is also possible to automatically perform pass / fail determination of the crimped state using image processing technology based on these images. At this time, the computer 2 functions as a pass / fail judgment device for judging pass / fail of the crimped state.
　その後、フロント側のスライダ３３は左方に移動し、クランプ１１は初期位置（カッターユニット９と正対する位置。図１参照）に戻る。一方、リア側のスライダ３３は更に左方に移動し、クランプ１２は電線１０を排出トレイ５に排出する。その後、リア側のスライダ３３は右方に移動し、クランプ１２は初期位置に戻る。 Thereafter, the slider 33 on the front side moves to the left, and the clamp 11 returns to the initial position (position facing the cutter unit 9; see FIG. 1). On the other hand, the rear slider 33 further moves to the left, and the clamp 12 discharges the electric wire 10 to the discharge tray 5. Thereafter, the rear slider 33 moves to the right, and the clamp 12 returns to the initial position.
　なお、端子１５の圧着不良が生じた場合には、電線処理装置１の動作を一時停止してもよく、また、コンピュータ２が表示装置３等を用いて、その旨の通知を行ってもよい。更に、排出トレイ５の他に、不良品を回収する回収トレイを別途設けておき、圧着不良が生じた電線１０を回収トレイに回収するようにしてもよい。 In addition, when the crimping | compression-bonding defect of the terminal 15 arises, the operation | movement of the electric wire processing apparatus 1 may be stopped temporarily, and the computer 2 may notify that using the display apparatus 3 grade | etc.,. . Further, in addition to the discharge tray 5, a separate collection tray for collecting defective products may be provided separately, and the electric wire 10 in which the crimping failure has occurred may be collected in the collection tray.
　端子１５の圧着不良には、端子１５を上面または下面から観察することによって検出できるものと、端子１５を側面から観察することによって検出できるものとが存在する。例えば、芯線の側方へのはみ出し、端子１５の横折れ等は、端子１５を上面または下面から観察することによって、比較的容易に検出することができる。一方、例えば、図７に示すような端子１５の上方または下方への折れ曲がり、すなわちベントアップまたはベントダウンは、端子１５を側方から観察しないと容易には検出できない。また、図８に示すようなランス変形、すなわち、端子１５のランス１５ａが下方に突出するような変形は、端子１５を側方から観察しないと容易には検出できない。 Defective crimping of the terminal 15 includes those that can be detected by observing the terminal 15 from the upper surface or the lower surface and those that can be detected by observing the terminal 15 from the side surface. For example, protrusion of the core wire to the side, lateral folding of the terminal 15, etc. can be detected relatively easily by observing the terminal 15 from the upper surface or the lower surface. On the other hand, for example, bending upward or downward of the terminal 15 as shown in FIG. 7, that is, vent-up or vent-down, cannot be easily detected unless the terminal 15 is observed from the side. Further, the lance deformation as shown in FIG. 8, that is, the deformation in which the lance 15a of the terminal 15 protrudes downward cannot be easily detected unless the terminal 15 is observed from the side.
　本実施形態によれば、クランプ１１，１２の移動中に、端子１５の側面がカメラ２１，２２と正対するように電線１０が回転する。そのため、端子１５の移動経路２５から離れた位置に配置されたカメラ２１，２２によって、端子１５の側面を撮像することができる。したがって、端子１５の側面を観察しないと検出できないような圧着不良を検出することが可能となる。 According to the present embodiment, while the clamps 11 and 12 are moving, the electric wire 10 is rotated so that the side surface of the terminal 15 faces the cameras 21 and 22. Therefore, the side surface of the terminal 15 can be imaged by the cameras 21 and 22 arranged at positions away from the movement path 25 of the terminal 15. Therefore, it is possible to detect a crimping failure that cannot be detected unless the side surface of the terminal 15 is observed.
　また、本実施形態によれば、カメラ２１，２２によって、端子１５の上面も撮像する。端子１５の上面および側面の両方を観察することができる。したがって、端子１５の圧着状態をより詳細に検査することができる。 Further, according to the present embodiment, the upper surfaces of the terminals 15 are also imaged by the cameras 21 and 22. Both the upper surface and the side surface of the terminal 15 can be observed. Therefore, the crimping state of the terminal 15 can be inspected in more detail.
　また、本実施形態によれば、端子１５の上面と側面とを同一のカメラ２１，２２で撮像することができる。そのため、カメラの設置個数を少なく抑えることができる。 Further, according to the present embodiment, the upper surface and the side surface of the terminal 15 can be imaged by the same cameras 21 and 22. Therefore, the number of cameras installed can be reduced.
　ただし、カメラ２１，２２の他に、端子１５の上面または下面を撮像する他の撮像装置を別途設けてもよい。例えば、図９および図１０に示すように、カメラ２１，２２の下方に、端子１５の下面を撮像するカメラ２３を配置してもよい。カメラ２３は、下方から端子１５を撮像する。この変形例では、カメラ２１，２２は端子１５の側面のみを撮像すればよい。なお、カメラ２１，２２によって端子１５の上面および側面を撮像することとすれば、端子１５の上面と下面と側面との撮像画像を得ることができ、より高度な検査を行うことができる。 However, in addition to the cameras 21 and 22, another imaging device that images the upper surface or the lower surface of the terminal 15 may be provided separately. For example, as shown in FIGS. 9 and 10, a camera 23 that images the lower surface of the terminal 15 may be disposed below the cameras 21 and 22. The camera 23 images the terminal 15 from below. In this modification, the cameras 21 and 22 need only image the side surface of the terminal 15. If the upper and side surfaces of the terminal 15 are imaged by the cameras 21 and 22, captured images of the upper surface, the lower surface, and the side surface of the terminal 15 can be obtained, and a more advanced inspection can be performed.
　図示は省略するが、端子１５の正面を撮像する他の撮像装置を別途設けることも可能である。これにより、端子１５の上面および／または下面と、側面と、正面とを撮像することができる。端子１５の上面および／または下面の撮像画像と、側面の撮像画像と、正面の撮像画像とにより、端子１５の圧着状態について、更に詳細な検査が可能となる。 Although illustration is omitted, it is possible to separately provide another imaging device for imaging the front surface of the terminal 15. Thereby, the upper surface and / or lower surface, side surface, and front surface of the terminal 15 can be imaged. A more detailed inspection can be performed on the crimped state of the terminal 15 by the captured image of the upper surface and / or the lower surface of the terminal 15, the captured image of the side surface, and the captured image of the front surface.
　本実施形態では、フロント側のカメラ２１は圧着ユニット１７の右側に配置されているが、カメラ２１を圧着ユニット１７の左側に配置してもよい。このように配置することにより、端子１５を圧着した後、圧着ユニット１７からカッターユニット９に戻る途中で、端子１５を撮像することができる。そのため、搬送時間の無駄を省くことができる。 In the present embodiment, the front-side camera 21 is disposed on the right side of the crimping unit 17, but the camera 21 may be disposed on the left side of the crimping unit 17. By arranging the terminals 15 in this manner, the terminals 15 can be imaged on the way from the crimping unit 17 to the cutter unit 9 after being crimped. For this reason, waste of transport time can be eliminated.
　本実施形態では、搬送ユニット１３，１４はクランプ１１，１２を左方および右方に搬送し、クランプ１１，１２は直線上を移動するものであった。しかし、搬送ユニット１３，１４は、クランプ１１，１２を鉛直軸周りに旋回させるものであってもよい。この場合、クランプ１１，１２の移動軌跡は平面視円弧状となる。しかし、このような場合であっても、クランプ１１，１２は電線１０の長手方向と直交する方向に移動することになる。ただし、クランプ１１，１２の移動方向は、電線１０の長手方向に対して、必ずしも直交していなくてもよい。クランプ１１，１２の移動方向は、電線１０の長手方向に対して斜めに交差する方向であってもよい。 In the present embodiment, the transport units 13 and 14 transport the clamps 11 and 12 to the left and right, and the clamps 11 and 12 move on a straight line. However, the transport units 13 and 14 may rotate the clamps 11 and 12 around the vertical axis. In this case, the movement trajectories of the clamps 11 and 12 are arcuate in plan view. However, even in such a case, the clamps 11 and 12 move in a direction orthogonal to the longitudinal direction of the electric wire 10. However, the moving directions of the clamps 11 and 12 are not necessarily orthogonal to the longitudinal direction of the electric wire 10. The direction of movement of the clamps 11 and 12 may be a direction that obliquely intersects the longitudinal direction of the electric wire 10.
　＜実施形態２＞
　実施形態１は、端子１５の側面を撮像するために、電線１０を９０度回転させるものであった。しかし、電線１０の回転角度は９０度に限られない。実施形態２は、電線１０を９０度未満の所定角度だけ回転させるものである。本実施形態においても、フロント側の検査装置とリア側の検査装置とは、同一の構成を有している。そこで、以下ではリア側の検査装置のみを説明し、フロント側の検査装置の説明は省略する。 <Embodiment 2>
In the first embodiment, the electric wire 10 is rotated 90 degrees in order to image the side surface of the terminal 15. However, the rotation angle of the electric wire 10 is not limited to 90 degrees. In the second embodiment, the electric wire 10 is rotated by a predetermined angle of less than 90 degrees. Also in this embodiment, the front-side inspection device and the rear-side inspection device have the same configuration. Therefore, only the rear side inspection apparatus will be described below, and description of the front side inspection apparatus will be omitted.
　図１１（ａ）～（ｃ）に示すように、本実施形態では、カメラ２２は、端子１５および電線１０の移動方向と斜めに交差する方向を向くように設置されている。ここでは、交差角θは４５度に設定されている。ただし、交差角θは９０度未満の角度であればよく、４５度以外の角度であってもよい。 As shown in FIGS. 11A to 11C, in this embodiment, the camera 22 is installed so as to face a direction obliquely intersecting the moving direction of the terminal 15 and the electric wire 10. Here, the intersection angle θ is set to 45 degrees. However, the crossing angle θ may be an angle less than 90 degrees and may be an angle other than 45 degrees.
　本実施形態では、スライダ３３は角度θだけ回転する。したがって、電線１０および端子１５も角度θだけ回転する。 In the present embodiment, the slider 33 rotates by an angle θ. Therefore, the electric wire 10 and the terminal 15 also rotate by the angle θ.
　本実施形態によれば、スライダ３３を９０度回転させなくても、角度θだけ回転させることによって、端子１５の側面を撮像することができる。スライダ３３が角度θだけ回転するまでの時間は、９０度回転するまでの時間よりも短い。そのため、本実施形態によれば、端子１５の側面を撮像するまでの時間を短縮することができる。また、スライダ３３が角度θだけ回転するために必要な電力は、９０度回転するまでに必要な電力よりも小さい、そのため、本実施形態によれば、端子１５の側面を撮像するために必要な電力を小さく抑えることができる。したがって、検査の迅速化および省エネルギー化を図ることができる。 According to this embodiment, the side surface of the terminal 15 can be imaged by rotating the slider 33 by the angle θ without rotating the slider 33 by 90 degrees. The time until the slider 33 rotates by the angle θ is shorter than the time until it rotates 90 degrees. Therefore, according to the present embodiment, it is possible to shorten the time until the side surface of the terminal 15 is imaged. Further, the power required for the slider 33 to rotate by the angle θ is smaller than the power required to rotate 90 degrees. Therefore, according to the present embodiment, it is necessary to image the side surface of the terminal 15. Electric power can be kept small. Therefore, speeding up of inspection and energy saving can be achieved.
　＜実施形態３＞
　前記実施形態１および２は、スライダ３３を回転させることにより、電線１０を回転させるものであった。しかし、電線１０を回転させる機構は、スライダ３３を回転させるものに限定される訳ではない。図１２（ａ）および（ｂ）に示すように、実施形態３では、クランプ１１，１２の爪３１が上下にスライド可能に形成されている。電線１０を狭持したまま一方の爪３１が他方の爪３１に対してスライドすると、電線１０は回転する。よって、爪３１をスライドさせることによって、端子１５の側面をカメラ２１，２２に正対させることができる。 <Embodiment 3>
In the first and second embodiments, the electric wire 10 is rotated by rotating the slider 33. However, the mechanism for rotating the electric wire 10 is not limited to that for rotating the slider 33. As shown in FIGS. 12A and 12B, in the third embodiment, the claws 31 of the clamps 11 and 12 are formed to be slidable up and down. When one claw 31 slides with respect to the other claw 31 while holding the electric wire 10, the electric wire 10 rotates. Therefore, the side surface of the terminal 15 can be opposed to the cameras 21 and 22 by sliding the claw 31.
　なお、爪３１をスライドさせる機構は何ら限定されず、従来から公知の各種機構を利用することができる。例えば、各爪３１に設けられたラックと、両ラックに噛み合うピニオンと、ピニオンを回転させるモータ等を用いることができる。 Note that the mechanism for sliding the claw 31 is not limited at all, and various conventionally known mechanisms can be used. For example, a rack provided on each claw 31, a pinion that meshes with both racks, a motor that rotates the pinion, and the like can be used.
　本実施形態においても、前記実施形態と同様の効果を得ることができる。また、爪３１をスライドさせるために必要な時間は、スライダ３３を回転させるために必要な時間よりも短い。また、爪３１をスライドさせるために必要な電力は、スライダ３３を回転させるために必要な電力よりも小さい。したがって、本実施形態によれば、端子１５の側面を撮像するために必要な時間を更に短縮することができ、また、更なる省エネルギー化を図ることができる。 Also in this embodiment, the same effect as that of the above embodiment can be obtained. Further, the time required to slide the claw 31 is shorter than the time required to rotate the slider 33. Further, the electric power necessary for sliding the claw 31 is smaller than the electric power necessary for rotating the slider 33. Therefore, according to the present embodiment, it is possible to further reduce the time required for imaging the side surface of the terminal 15 and to further save energy.
