As rotation means 10 for rotating at least either of the projection shape information acquisition means 31 and the crimp terminal 510 about a terminal axis direction of the crimp terminal 510 rotates the crimp terminal 510 relative to the projection shape information acquisition means 31, the projection shape information acquisition means 31 acquires projection shape information based on a projection shape of projection of a predetermined axial shape information acquisition target portion 531 of the crimp terminal 510.

Description

この発明は、圧着端子の圧着形状について例えば、検査を行ううえで必要となる圧着形状に関する圧着形状情報を取得する圧着形状情報取得方法、及び、圧着形状情報取得装置に関する。   The present invention relates to a crimping shape information acquisition method and a crimping shape information acquisition device for acquiring, for example, a crimping shape information related to a crimping shape necessary for performing an inspection on a crimping shape of a crimp terminal.

絶縁被覆を剥がした導体露出部を先端側に備えた被覆電線における導体露出部に対して圧着端子を圧着するに伴って、例えば、圧着部と、該圧着部よりも端子軸方向の端子先端側部との間で端子軸方向回りに捩れが生じたり、圧着後の圧着端子が広がることがある。   As the crimp terminal is crimped to the conductor exposed portion of the covered electric wire provided with the conductor exposed portion on the distal end side with the insulation coating removed, for example, the crimp portion and the terminal distal end side in the terminal axial direction from the crimp portion Twist may occur around the terminal axis direction between the two parts, and the crimp terminal after crimping may spread.

導体露出部に対して圧着端子を圧着するに伴って、上述したように、圧着端子の圧着形状に変形が生じるが、圧着後の圧着端子は、所定の圧着形状を満たす必要がある。
これは、圧着後の圧着端子が所定の圧着形状を満たさない場合には、良好な電気的な接続状態を得ることができないおそれが生じ、また、圧着端子の圧着に伴って、例えば、前記圧着部の全体を絶縁樹脂によって完全に封止できないという課題や、圧着端子の変形部分やこれら変形部分を封止した絶縁樹脂が、コネクタハウジングに挿着する際に干渉し、コネクタハウジングの挿入孔に圧着端子をスムーズに挿入できないという課題も生じることになる。
As described above, as the crimp terminal is crimped to the exposed conductor portion, the crimp shape of the crimp terminal is deformed. However, the crimp terminal after the crimping needs to satisfy a predetermined crimp shape.
This is because, if the crimp terminal after crimping does not satisfy a predetermined crimp shape, there is a possibility that a good electrical connection state cannot be obtained. The problem that the entire part cannot be completely sealed with insulating resin, the deformed part of the crimp terminal, and the insulating resin that seals these deformed parts interfere when inserted into the connector housing, and enter the insertion hole of the connector housing. The problem that a crimp terminal cannot be inserted smoothly also arises.

このため、通常、圧着後の圧着端子が被覆電線に対して所定の圧着形状を満たしているか否かの検査が行われている。このような検査は、従来より、ノギスやマイクロメータなどのゲージを用いて手動で行われることが殆どであるが、計測誤差や労力も大きくなるという課題を有していた。   For this reason, it is usually inspected whether or not the crimp terminal after crimping satisfies a predetermined crimping shape with respect to the covered electric wire. Conventionally, such inspections are mostly performed manually using a gauge such as a caliper or a micrometer, but have the problem of increasing measurement errors and labor.

中でも、圧着端子の圧着部と端子先端部との端子軸方向回りの捩れ(ローリング角度)を検査する際においては、圧着端子を端子軸方向に対して直交する直交断面があらわれるように切断するなど、圧着端子を破壊する必要があった。
このため、圧着端子の上述したローリング角度を検査するに際して、所定の圧着端子を上述したサンプルとして余分に作成しておくなど、労力やコストを要するという課題を有していた。
In particular, when inspecting the twisting (rolling angle) between the crimping part of the crimping terminal and the terminal tip part in the terminal axis direction, the crimping terminal is cut so that an orthogonal cross section perpendicular to the terminal axis direction appears. It was necessary to destroy the crimp terminal.
For this reason, when inspecting the above-mentioned rolling angle of a crimp terminal, there existed a subject that labor and cost were required, such as preparing a predetermined crimp terminal extra as a sample mentioned above.

このような課題に対して下記特許文献1における「端子圧着寸法測定装置」が提案されている。
特許文献1における「端子圧着寸法測定装置」は、圧着端子に向けて光ビームを出射する発光素子と、圧着端子を載置する基準面を有する端子受け部と、圧着端子を基準面の側へ押圧する押圧する端子押圧部材とで構成している。
In order to solve such a problem, a “terminal crimping dimension measuring device” in the following Patent Document 1 has been proposed.
The “terminal crimping dimension measuring device” in Patent Document 1 is a light emitting element that emits a light beam toward a crimping terminal, a terminal receiving portion having a reference surface on which the crimping terminal is placed, and the crimping terminal toward the reference surface. It is comprised with the terminal press member to press.

特許文献1における「端子圧着寸法測定装置」によれば、圧着端子を基準面に載置した状態で、端子押圧部材により圧着端子を基準面の側へ押圧することにより、基準面に対して圧着端子を密着させることが可能となるため、基準面に対しての圧着部の浮きや傾きを防止でき、基準面に対する圧着端子における所定の寸法を、発光素子を用いて測定できるというものである。   According to the “terminal crimping dimension measuring device” in Patent Document 1, the crimping terminal is pressed against the reference surface by pressing the crimping terminal toward the reference surface with the terminal pressing member in a state where the crimping terminal is placed on the reference surface. Since the terminals can be brought into close contact with each other, it is possible to prevent the crimped portion from being lifted or inclined with respect to the reference surface, and a predetermined dimension of the crimp terminal with respect to the reference surface can be measured using a light emitting element.

しかし、圧着後の圧着端子は、圧着により、その圧着部の外周形状が凹凸形状、湾曲形状、或いは屈曲形状に変形するため、端子押圧部材で圧着端子を押圧しても、圧着端子が基準面に対して傾いて密着せずに浮き上がった状態となることや、がたつくなどして安定して押圧した状態を維持できないとう問題が生じるおそれがあった。   However, the crimp terminal after crimping is deformed into an irregular shape, a curved shape, or a bent shape by crimping, so even if the crimp terminal is pressed by the terminal pressing member, the crimp terminal is still in the reference plane. There is a possibility that a problem arises in that it cannot be maintained in a state where it is tilted with respect to the surface and is lifted up without being in close contact with each other, or a state where it is stably pressed due to rattling or the like.

このため、「端子圧着寸法測定装置」は、たとえ端子押圧部材で圧着端子を基準面に押し付けた状態で基準面に対しての圧着端子の所定の寸法を計測しても、その寸法は、圧着端子を基準面に対して密着させた状態で計測した寸法とは限らないため、正確な寸法を測定できないおそれを有するという難点があった。   For this reason, the “terminal crimping dimension measuring device” measures the predetermined dimension of the crimping terminal against the reference surface even when the crimping terminal is pressed against the reference surface with the terminal pressing member. Since the dimensions are not necessarily measured in a state in which the terminal is in close contact with the reference surface, there is a problem in that there is a possibility that an accurate dimension cannot be measured.

さらに、「端子圧着寸法測定装置」は、圧着端子が基準面に対して浮き上がった状態や、がたついた状態とならないように、端子押圧部材で基準面に対してしっかりと圧着端子を押圧した場合、圧着端子が不測に変形するおそれを有するという難点もあった。   Furthermore, the “terminal crimping dimension measuring device” firmly presses the crimping terminal against the reference surface with the terminal pressing member so that the crimping terminal does not float or rattle against the reference surface. In some cases, the crimp terminal has a risk of unexpected deformation.

そこでこの発明は、電線に圧着した圧着後の圧着端子の圧着形状に関する圧着形状情報を正確、且つ容易に取得することができる圧着形状情報取得方法、及び、圧着形状情報取得装置の提供を目的とする。   Then, this invention aims at provision of the crimping shape information acquisition method and crimping shape information acquisition device which can acquire correctly and easily the crimping shape information about the crimping shape of the crimp terminal after crimping to the electric wire. To do.

本発明は、導体を絶縁被覆で被覆して構成するとともに、前記導体の先端側の前記絶縁被覆を剥がした導体露出部を先端側に備えた被覆電線における少なくとも前記導体露出部に対して圧着端子を圧着接続した圧着部を有する圧着端子付き電線における前記圧着端子の圧着形状に関する圧着形状情報を取得する圧着形状情報取得方法であって、前記圧着端子に対して所定間隔隔てた箇所に投影形状情報取得手段を配置し、前記投影形状情報取得手段と前記圧着端子のうち、少なくとも一方を前記圧着端子の端子軸方向回りに回転させる回転手段により、前記投影形状情報取得手段に対して前記圧着端子を相対回転させ、制御手段により、前記回転手段による、前記圧着端子の前記投影形状情報取得手段に対する相対回転を制御するとともに、前記投影形状情報取得手段による前記投影形状情報の取得を制御することを特徴とする。   The present invention is configured by covering a conductor with an insulating coating, and crimping a terminal with respect to at least the conductor exposed portion in a covered electric wire provided with a conductor exposed portion on the distal end side where the insulating coating on the distal end side of the conductor is peeled off A crimping shape information acquisition method for acquiring crimping shape information related to the crimping shape of the crimping terminal in the electric wire with the crimping terminal having the crimping portion connected by crimping, and projection shape information at a position spaced apart from the crimping terminal by a predetermined distance An acquisition unit is arranged, and the crimp terminal is rotated with respect to the projection shape information acquisition unit by a rotation unit that rotates at least one of the projection shape information acquisition unit and the crimp terminal around a terminal axis direction of the crimp terminal. Control the relative rotation of the crimping terminal with respect to the projection shape information acquisition unit by the rotation unit, and control the relative rotation. And controlling the acquisition of said projection shape information by serial projected shape information acquiring unit.

電線に圧着した圧着後の圧着端子の圧着形状に関する圧着形状情報を正確、且つ、容易に取得することができる。   Crimp shape information regarding the crimp shape of the crimp terminal after crimping on the electric wire can be obtained accurately and easily.

詳しくは、前記回転手段により、前記投影形状情報取得手段に対して前記圧着端子を相対回転するに応じた投影形状情報を前記投影形状情報取得手段によって取得することができる。   Specifically, the projection shape information acquisition unit can acquire the projection shape information corresponding to the relative rotation of the crimp terminal with respect to the projection shape information acquisition unit.

例えば、投影形状情報が任意に設定した閾値を超える結果となった圧着端子を、不良品として判別することができる。
よって、導体露出部を圧着端子で圧着するに伴って生じる不具合の有無を検査することができる。
For example, a crimp terminal that results in the projection shape information exceeding an arbitrarily set threshold value can be determined as a defective product.
Therefore, it is possible to inspect for the presence or absence of problems that occur when the conductor exposed portion is crimped by the crimp terminal.

その他にも、前記投影形状情報取得手段により取得した投影形状情報を基に、例えば、形状情報取得対象箇所における所手の寸法を測定することができる。
従って、人がゲージを用いて圧着端子の各部寸法を測定することで圧着形状情報を取得する場合、測定誤差や、精度にばらつきが生じ易いが、このようなヒューマンエラーの影響を受けることがなく、精度よく、スムーズに圧着端子の投影形状情報を取得することができる。
In addition, based on the projection shape information acquired by the projection shape information acquisition unit, for example, the size of the hand at the shape information acquisition target location can be measured.
Therefore, when a person acquires the crimping shape information by measuring the dimensions of each part of the crimping terminal using a gauge, measurement errors and accuracy are likely to vary, but without being affected by such a human error. The projection shape information of the crimp terminal can be acquired accurately and smoothly.

さらに、投影形状情報を取得する際において、例えば、前記投影形状情報取得手段の基準箇所と圧着端子の基準箇所とを合わせるなどの手間を要することがなく、スムーズに圧着形状情報を取得できるとともに、例えば、基準箇所に合わせる際に生じる誤差の影響を受けることがないため、正確に所望の投影形状情報を取得できる。   Furthermore, when acquiring the projection shape information, for example, it is possible to smoothly acquire the crimping shape information without requiring troubles such as matching the reference location of the projection shape information acquisition means and the reference location of the crimp terminal, For example, desired projection shape information can be obtained accurately because it is not affected by errors that occur when matching with a reference location.

さらにまた、投影形状情報を取得する際に、圧着端子を押圧したり、切断するなどして破壊するなどの変形を伴うことがないため、投影形状情報を取得するために別途、サンプルとしての余分な圧着端子を作成する労力、コストを要することなく、必要最小限の圧着端子により圧着端子の投影形状情報を取得することができる。   Furthermore, when acquiring the projection shape information, there is no deformation such as pressing or cutting the crimping terminal and destroying it. Therefore, an extra sample is required to acquire the projection shape information. The projection shape information of the crimp terminal can be acquired with the minimum necessary crimp terminal without requiring labor and cost for creating a simple crimp terminal.

前記投影形状情報取得手段は、前記回転手段によって、前記配置手段を前記投影形状情報取得手段に対して相対回転させている最中に前記投影形状情報を取得するに限らず、相対回転を停止している間に取得でもよい。   The projection shape information acquisition means is not limited to acquiring the projection shape information during the rotation of the arrangement means relative to the projection shape information acquisition means by the rotation means, but stops the relative rotation. You may get while you are.

前記投影形状情報取得手段は、例えば、光学センサ、カメラ、風を送るブロアと風圧センサ、赤外線照射器と赤外線受信器、或いは、送風ブロアと風量センサで構成することができるが、投影形状情報を取得可能な手段であれば特に限定しない。   The projection shape information acquisition means can be composed of, for example, an optical sensor, a camera, a blower and a wind pressure sensor for sending wind, an infrared irradiator and an infrared receiver, or a blower and an air volume sensor. There is no particular limitation as long as it can be acquired.

前記回転手段は、例えば、モータ、シリンダなどにより自動で回転することができることを上げることができる。さらに、手動により軸回りに回転可能に保持するベアリングや回転を補助する回転レバーなども含む。   It can be raised that the rotating means can be automatically rotated by, for example, a motor, a cylinder or the like. Further, it includes a bearing that is manually held to be rotatable about an axis, a rotation lever that assists rotation, and the like.

前記投影形状情報取得手段は、前記制御手段と別に構成してもよく、前記制御手段の一部として一体に構成してもよい。   The projection shape information acquisition unit may be configured separately from the control unit, or may be configured integrally as a part of the control unit.

この発明の態様として、回転角度取得手段により、前記投影形状情報取得手段に対して前記圧着端子が相対回転する回転角度に関する回転角度情報を取得し、関連付処理手段により、前記回転角度取得手段で取得した回転角度情報と、前記投影形状情報取得手段で取得した投影形状情報とを関連付け処理し、記憶手段により、前記関連付処理手段により関連付けた前記回転角度情報と前記投影形状情報とを記憶することができる。   As an aspect of the present invention, the rotation angle acquisition unit acquires rotation angle information related to the rotation angle at which the crimp terminal relatively rotates with respect to the projection shape information acquisition unit, and the association processing unit acquires the rotation angle information. The acquired rotation angle information and the projection shape information acquired by the projection shape information acquisition means are associated with each other, and the storage means stores the rotation angle information and the projection shape information associated by the association processing means. be able to.

上述したように、回転角度情報と投影形状情報とを関連付けすることにより、前記圧着端子の軸方向の所定の形状情報取得対象箇所において、端子軸方向回りにおける、いずれの角度において最も変形が生じているかを特定することが可能となる。   As described above, by associating the rotation angle information with the projection shape information, in the predetermined shape information acquisition target location in the axial direction of the crimp terminal, the most deformation occurs at any angle around the terminal axis direction. It becomes possible to specify whether or not.

このように、変形が生じた不具合箇所を迅速、且つ正確に特定することで、例えば、不具合箇所の矯正、不具合箇所の傾向を解明、或いは、不具合が生じる原因究明といった対策を容易に施すことができる。   In this way, by quickly and accurately identifying the defect location where the deformation has occurred, for example, it is possible to easily take measures such as correcting the failure location, elucidating the tendency of the failure location, or investigating the cause of the failure. it can.

この発明の態様として、前記回転手段としての回転保持手段により、前記圧着端子の端子軸方向における前記圧着部よりも先端側部分を保持するとともに、前記圧着端子付き電線を端子軸方向回りに回転させることができる。   As an aspect of the present invention, the rotation holding means as the rotating means holds the tip side portion of the crimp terminal in the terminal axis direction of the crimp terminal and rotates the electric wire with the crimp terminal around the terminal axis direction. be able to.

上述した構成によれば、前記回転保持手段により、前記圧着端子を保持した状態で端子軸方向回りに回転させることができるため、前記投影形状情報取得手段を端子軸方向回りに回転させる場合と比較して、小さな回転半径で端子軸方向回りに回転させることができるため、前記回転手段の構成をシンプルな構成とすることができるとともに、少ないエネルギーでスムーズに回転させることができる。   According to the configuration described above, the rotation holding unit can be rotated around the terminal axis direction while holding the crimp terminal, so that the projection shape information acquisition unit is compared with the case where the projection shape information acquisition unit is rotated around the terminal axis direction. And since it can be made to rotate around a terminal axis direction with a small rotation radius, while being able to make the structure of the said rotation means simple, it can be rotated smoothly with little energy.

またこの発明の態様として、前記投影形状情報取得手段を構成する投光手段により、前記形状情報取得対象箇所に向けて投光し、前記投影形状情報取得手段を構成する受光手段により、該投光手段の投影光の投光により投影した投影形状に基づく投影形状情報としての投影光を受光することができる。   Further, as an aspect of the present invention, the light projecting unit constituting the projection shape information obtaining unit projects light toward the shape information obtaining target location, and the light receiving unit constituting the projection shape information obtaining unit performs the light projection. The projection light as projection shape information based on the projection shape projected by the projection of the projection light of the means can be received.

上述した構成によれば、投光手段が投光した投影光によって投影した投影形状に基づく投影光を受光手段で受光することで圧着形状情報を取得するため、例えば、CCDカメラを用いる場合のように、高価な装置や複雑なシステムを必要とせずに、簡素な構成によって投影光を投影形状情報として確実に取得できる。   According to the above-described configuration, the crimping shape information is acquired by receiving the projection light based on the projection shape projected by the projection light projected by the light projecting unit by the light receiving unit. For example, as in the case of using a CCD camera. In addition, it is possible to reliably acquire projection light as projection shape information with a simple configuration without requiring an expensive device or a complicated system.

前記投影形状情報取得手段を光学センサで構成する場合、前記投光手段と前記受光手段とで構成したものを用いることができる。
詳しくは、前記投光手段を、前記圧着端子に対して所定間隔を隔てて配置するとともに、前記受光手段を前記圧着端子に対して前記投光手段と反対側に配置することができる。或いは、前記受光手段は、前記投光手段が投光した投影光が、所定の形状情報取得対象箇所に対して反射した反射光を受光する構成であってもよい。
In the case where the projection shape information acquisition means is constituted by an optical sensor, the one constituted by the light projecting means and the light receiving means can be used.
Specifically, the light projecting unit may be disposed at a predetermined interval with respect to the crimp terminal, and the light receiving unit may be disposed on the opposite side of the light projecting unit with respect to the crimp terminal. Alternatively, the light receiving means may be configured to receive the reflected light reflected by the projection light projected by the light projecting means with respect to a predetermined shape information acquisition target location.

またこの発明の態様として、前記形状情報取得対象箇所と前記投影形状情報取得手段とが対向する対向方向に直交し、且つ、前記端子軸方向に直交する方向を直交方向に設定し、前記投影形状情報を、前記形状情報取得対象箇所を投影した投影箇所における、前記直交方向の寸法に関する投影直交寸法情報に設定し、前記圧着端子の前記投影形状情報取得手段に対する相対回転に伴って、前記形状情報取得対象箇所における投影直交寸法情報が最小、又は最大となる変曲値を、前記圧着端子の前記形状情報取得対象箇所の前記直交方向の寸法である直交寸法に設定することができる。   Further, as an aspect of the present invention, a direction orthogonal to a facing direction in which the shape information acquisition target portion and the projection shape information acquisition unit face each other and a direction orthogonal to the terminal axis direction is set to an orthogonal direction, and the projection shape Information is set in the projection orthogonal dimension information regarding the dimension in the orthogonal direction at the projection location where the shape information acquisition target location is projected, and the shape information is associated with relative rotation of the crimp terminal with respect to the projection shape information acquisition means. The inflection value at which the projected orthogonal dimension information at the acquisition target location is minimum or maximum can be set to the orthogonal dimension that is the dimension in the orthogonal direction of the shape information acquisition target location of the crimp terminal.

上述した構成によれば、前記形状情報取得対象箇所における投影直交寸法情報の変曲値を、該形状情報取得対象箇所の直交寸法として特定できる。これにより、前記圧着端子を前記導体露出部に対して圧着するに伴って、前記形状情報取得対象箇所が前記被覆電線に対して前記端子軸方向回りにローリング変形した場合であっても、ローリング変形の影響を受けずに前記形状情報取得対象箇所の正確な直交寸法を特定することができる。   According to the configuration described above, the inflection value of the projected orthogonal dimension information at the shape information acquisition target location can be specified as the orthogonal dimension of the shape information acquisition target location. Thereby, even when the shape information acquisition target portion is rolling deformed around the terminal axis direction with respect to the covered electric wire as the crimping terminal is crimped to the exposed conductor portion, rolling deformation is caused. It is possible to specify an accurate orthogonal dimension of the shape information acquisition target portion without being affected by the above.

すなわち、前記形状情報取得対象箇所の前記直交方向の寸法を、形状情報取得対象箇所がローリング変形している場合としていない場合とで同じ値として特定できるため、ローリング変形しているか否かに関わらず、前記形状情報取得対象箇所の正確な直交寸法を特定することができる。   That is, since the dimension in the orthogonal direction of the shape information acquisition target portion can be specified as the same value in the case where the shape information acquisition target portion is not deformed by rolling, regardless of whether it is rolling deformed or not. The exact orthogonal dimension of the shape information acquisition target location can be specified.

またこの発明の態様として、前記圧着端子の前記投影形状情報取得手段に対する相対回転に伴って、前記回転角度取得手段に対して前記圧着端子の上面、或いは底面が略対向した状態において、前記投影直交寸法情報が最小、又は最大となる変曲値を、前記直交寸法として、前記形状情報取得対象箇所の幅寸法に設定することができる。   Further, as an aspect of the present invention, the projection orthogonality is obtained in a state where the upper surface or the bottom surface of the crimp terminal is substantially opposed to the rotation angle acquisition unit as the crimp terminal is relatively rotated with respect to the projection shape information acquisition unit. The inflection value at which the dimension information is minimum or maximum can be set as the width dimension of the shape information acquisition target portion as the orthogonal dimension.

上述した構成によれば、前記形状情報取得対象箇所が前記被覆電線に対して前記端子軸方向回りにローリング変形した場合であっても、ローリング変形の影響を受けずに前記形状情報取得対象箇所の正確な幅寸法を特定することができる。   According to the configuration described above, even if the shape information acquisition target location is rolling deformed around the terminal axis direction with respect to the covered electric wire, the shape information acquisition target location is not affected by rolling deformation. An accurate width dimension can be specified.

すなわち、前記形状情報取得対象箇所の幅寸法を、形状情報取得対象箇所がローリング変形している場合としていない場合とで同じ値として特定できるため、ローリング変形しているか否かに関わらず、前記形状情報取得対象箇所の正確な幅寸法を特定することができる。   That is, since the width dimension of the shape information acquisition target portion can be specified as the same value in the case where the shape information acquisition target portion is not deformed by rolling, the shape is determined regardless of whether it is rolling deformed or not. It is possible to specify an accurate width dimension of the information acquisition target portion.

またこの発明の態様として、前記圧着端子の前記投影形状情報取得手段に対する相対回転に伴って、前記回転角度取得手段に対して前記圧着端子の側面が略対向した状態において、前記投影直交寸法情報が最小、又は最大となる変曲値を、前記直交寸法として、前記形状情報取得対象箇所の高さ寸法に設定することができる。   Further, as an aspect of the present invention, the projection orthogonal dimension information is obtained when the side surface of the crimp terminal is substantially opposed to the rotation angle acquisition unit in association with the relative rotation of the crimp terminal with respect to the projection shape information acquisition unit. The minimum or maximum inflection value can be set as the orthogonal dimension to the height dimension of the shape information acquisition target portion.

上述した構成によれば、前記形状情報取得対象箇所が前記被覆電線に対して前記端子軸方向回りにローリング変形した場合であっても、ローリング変形の影響を受けずに前記形状情報取得対象箇所の正確な高さ寸法を特定することができる。   According to the configuration described above, even if the shape information acquisition target location is rolling deformed around the terminal axis direction with respect to the covered electric wire, the shape information acquisition target location is not affected by rolling deformation. An accurate height dimension can be specified.

すなわち、前記形状情報取得対象箇所の高さ寸法を、形状情報取得対象箇所がローリング変形している場合としていない場合とで同じ値として特定できるため、ローリング変形しているか否かに関わらず、前記形状情報取得対象箇所の正確な高さ寸法を特定することができる。   That is, because the height dimension of the shape information acquisition target location can be specified as the same value in the case where the shape information acquisition target location is not rolling deformed, regardless of whether it is rolling deformed or not It is possible to specify the exact height dimension of the shape information acquisition target portion.

またこの発明の態様として、前記回転手段により、前記回転角度取得手段に対して前記圧着端子の側面が略対向する角度から前記回転角度取得手段に対して前記圧着端子の上面、或いは、底面が略対向する角度となるまで前記圧着端子が前記投影形状情報取得手段に対して端子軸回りに90度以上の所定の角度範囲で相対回転させ、前記圧着端子が前記投影形状情報取得手段に対して所定の角度範囲で相対回転するに伴って、前記回転角度取得手段に対して前記圧着端子の側面が略対向した状態において、前記直交寸法として、前記形状情報取得対象箇所の幅寸法を前記投影形状情報取得手段により取得するとともに、前記回転角度取得手段に対して前記圧着端子の上面、或いは、底面が略対向した状態において、前記直交寸法として、前記直交寸法として前記形状情報取得対象箇所の高さ寸法を前記投影形状情報取得手段により取得することができる。   Further, as an aspect of the present invention, the upper surface or the bottom surface of the crimp terminal with respect to the rotation angle acquisition means is substantially from the angle at which the side surface of the crimp terminal substantially faces the rotation angle acquisition means by the rotation means. The crimp terminal is rotated relative to the projection shape information acquisition unit at a predetermined angle range of 90 degrees or more around the terminal axis until the opposing angle is reached, and the crimp terminal is predetermined with respect to the projection shape information acquisition unit. In the state where the side surface of the crimp terminal is substantially opposed to the rotation angle acquisition means as the relative rotation is performed within the angle range, the width dimension of the shape information acquisition target portion is the projection shape information as the orthogonal dimension.

例えば、レーザー光Lが端子高さ方向面512Hに対して直交する場合における投影直交寸法は、導体露出部501の高さ寸法LHとなる。レーザー光Lが端子幅方向面512Wに対して直交する場合における投影直交寸法Lは、導体露出部501の幅寸法LWとなる。   For example, the projected orthogonal dimension when the laser beam L is orthogonal to the terminal height direction surface 512H is the height dimension LH of the conductor exposed portion 501. The projected orthogonal dimension L when the laser beam L is orthogonal to the terminal width direction surface 512W is the width dimension LW of the conductor exposed portion 501.

なお、ボックス部511は端子チャック部21によりZ方向に沿って保持されているため、厳密には、ボックス部511が電線圧着部530に対してローリング変形している場合であっても、電線圧着部530がボックス部511に対してローリング変形していることを検出できる。このため、ボックス部511と端子チャック部21とのうち、いずれの側がローリング変形している場合も、その変形を検出できる。
なお、図7中の第1圧着端子510A、及び第2圧着端子510Bの回転角度は、説明し易いように実際の回転角度よりも大きな角度で示している。
In addition, since the box part 511 is held along the Z direction by the terminal chuck part 21, strictly speaking, even when the box part 511 is rolling-deformed with respect to the wire crimping part 530, the wire crimping is performed. It can be detected that the part 530 is rolling deformed with respect to the box part 511. For this reason, even when any of the box part 511 and the terminal chuck part 21 is rolling-deformed, the deformation can be detected.
In addition, the rotation angle of the first crimp terminal 510A and the second crimp terminal 510B in FIG. 7 is shown as an angle larger than the actual rotation angle for easy explanation.

本検査方法は、まず、初期姿勢として圧着端子510が前記基準姿勢、すなわち、圧着端子510の端子高さ方向面512Hが投光器31Xと対向する姿勢となるように圧着端子510を回転軸Z1回りに回転させる。   In this inspection method, first, the crimp terminal 510 is rotated around the rotation axis Z1 so that the crimp terminal 510 is in the reference position as an initial position, that is, the terminal height direction surface 512H of the crimp terminal 510 is opposed to the projector 31X. Rotate.

なお、ここでは、前記基準姿勢において、圧着端子510の端子高さ方向面512Hを投光器31Xと対向させているが、圧着端子510にローリング変形がないとの仮定を前提とした表現である。すなわち、厳密には、圧着端子510がローリング変形している場合には、そのローリングしている角度分だけ投光器31Xとの対向方向に対して端子高さ方向面512Hが傾いている。   Here, in the reference posture, the terminal height direction surface 512H of the crimp terminal 510 is opposed to the projector 31X, but the expression is based on the assumption that the crimp terminal 510 is not subjected to rolling deformation. That is, strictly speaking, when the crimp terminal 510 is deformed by rolling, the terminal height direction surface 512H is inclined with respect to the direction facing the projector 31X by the rolling angle.

圧着端子510が前記基準姿勢になるよう回転軸Z1回りに回転させた後、圧着端子510を基準姿勢に対して回転軸Z1を中心として反時計回りR1、或いは時計回りR2に約5度ずつ(±約5度)回転させる。   After the crimp terminal 510 is rotated around the rotation axis Z1 so as to be in the reference posture, the crimp terminal 510 is rotated about 5 degrees counterclockwise R1 or clockwise R2 around the rotation axis Z1 with respect to the reference posture ( Rotate about ± 5 degrees.

圧着端子510を回転させている間、図4(a)に示すように、投光器31Xから投光されるレーザー光Lを導体圧着部531に投光するとともに、導体圧着部531の投影形状に基づく投影形状情報を受光量として受光器31Yにより受光する。   While rotating the crimp terminal 510, as shown in FIG. 4A, the laser light L projected from the projector 31X is projected onto the conductor crimp part 531 and based on the projected shape of the conductor crimp part 531. The light receiving device 31Y receives the projection shape information as the amount of received light.

圧着端子510の投影器31Xに対する角度(姿勢)に応じて、投影直交寸法Lが変わるため、受光器31Yで受光する受光量が変化する。そして、導体圧着部531の端子高さ方向面512Hがレーザー光Lの進む方向に対して垂直となったとき、圧着端子510の回転軸Z1回りの姿勢において、レーザー光Lは圧着端子510によって最も遮られない姿勢となるため、図5のグラフ中に示す光量の値(Y)ように、受光器31Yにより受光する受光量が最も大きくなる。   Since the projection orthogonal dimension L changes according to the angle (attitude) of the crimp terminal 510 with respect to the projector 31X, the amount of light received by the light receiver 31Y changes. When the terminal height direction surface 512H of the conductor crimping portion 531 is perpendicular to the direction in which the laser beam L travels, the laser beam L is most transmitted by the crimping terminal 510 in the posture around the rotation axis Z1 of the crimping terminal 510. Since the posture is not obstructed, the amount of light received by the light receiver 31Y becomes the largest as shown by the light amount value (Y) shown in the graph of FIG.

よって、CPU52では、記憶部53に記憶された、受光量と寸法情報とを関連付けた所定のデータに基づいて、正確な端子高さ方向面512Hの寸法、すなわち、導体圧着部531の高さ寸法を特定することができる。   Therefore, in the CPU 52, based on the predetermined data stored in the storage unit 53 that associates the received light amount with the dimension information, the accurate dimension of the terminal height direction surface 512 </ b> H, that is, the height dimension of the conductor crimping unit 531. Can be specified.

詳しくは、例えば、受光量と端子高さ方向面512Hの寸法との関係を示す記憶部53に記憶されたデータを基にして、受光器31Yにより受光した最も大きな受光量から正確な端子高さ方向面512Hの寸法、すなわち、導体圧着部531の高さ寸法を特定することができる。   Specifically, for example, based on the data stored in the storage unit 53 indicating the relationship between the received light amount and the dimension of the terminal height direction surface 512H, the accurate terminal height is determined from the largest received light amount received by the light receiver 31Y. The dimension of the direction surface 512H, that is, the height dimension of the conductor crimping portion 531 can be specified.

同時に、図5のグラフに示すように、受光器31Yにより受光する受光量が最も大きくなったときの圧着端子510の基準姿勢に対する回転軸Z1回りの回転角度を、ローリング変形している圧着端子510のローリング角度(α)と特定できる。
詳しくは、圧着端子510を回転させている間、エンコーダ11により検出した圧着端子510の回転角度に関する回転角度情報と、受光器31Yにより受光した受光量に関する投影形状情報とを関連付けて記憶部53に記憶している。
At the same time, as shown in the graph of FIG. 5, the rotation angle around the rotation axis Z <b> 1 with respect to the reference posture of the crimp terminal 510 when the amount of light received by the light receiver 31 </ b> Y becomes the largest is the crimp terminal 510 that is rolling deformed. The rolling angle (α) can be specified.
Specifically, while rotating the crimp terminal 510, the rotation angle information related to the rotation angle of the crimp terminal 510 detected by the encoder 11 and the projection shape information related to the amount of received light received by the light receiver 31Y are associated with each other in the storage unit 53. I remember it.

これにより、受光器31Yにより受光する受光量が最も大きくなったときの投影形状情報(Y)に対応する回転角度情報を割り出すことができ、この回転角度情報を圧着端子510のローリング角度(α)と特定できる。   As a result, rotation angle information corresponding to the projection shape information (Y) when the amount of light received by the light receiver 31Y becomes the largest can be determined, and this rotation angle information is used as the rolling angle (α) of the crimp terminal 510. Can be specified.

また、上述した検査方法においては、レーザー光Lを導体圧着部531の端子高さ方向面512Hに投光して投影直交寸法Lとして、導体圧着部531の高さ寸法LHの計測等を行ったが、これに限定せず、レーザー光Lを端子幅方向面512Wに投光して導体圧着部531の幅寸法LWの計測等を行ってもよい。
導体圧着部531の幅寸法LWの計測についても、上述した導体圧着部531の高さ寸法LHの計測の場合と同じ要領で行うことができるため、その説明は省略する。
In the inspection method described above, the laser beam L is projected onto the terminal height direction surface 512H of the conductor crimping portion 531 to obtain the projection orthogonal dimension L, and the height dimension LH of the conductor crimping portion 531 is measured. However, the present invention is not limited to this, and the laser beam L may be projected onto the terminal width direction surface 512W to measure the width LW of the conductor crimping portion 531 or the like.
The measurement of the width dimension LW of the conductor crimping portion 531 can also be performed in the same manner as in the case of the measurement of the height dimension LH of the conductor crimping portion 531 described above.

また、上述した検査方法による寸法計測箇所は、導体圧着部531に限らず、絶縁被覆圧着部532、或いは、その他の部分を計測対象としてもよい。   Moreover, the dimension measurement location by the inspection method described above is not limited to the conductor crimping portion 531, and the insulation coating crimping portion 532 or other portions may be measured.

さらにまた、上述した検査方法においては、レーザー光Lは、圧着端子510によって遮られることにより、受光器31Yにより受光する受光量が小さくなるため、受光器31Yにより受光する受光量が最も大きくなった場合を正確な端子高さ方向面512Hの寸法(導体圧着部531の高さ寸法)として特定したが、この検査方法に限定しない。   Furthermore, in the inspection method described above, the amount of light received by the light receiver 31Y is the largest because the amount of light received by the light receiver 31Y is reduced by being blocked by the crimp terminal 510. Although the case was specified as an accurate dimension of the terminal height direction surface 512H (height dimension of the conductor crimping portion 531), it is not limited to this inspection method.

例えば、逆に受光器31Yにより受光する受光量が最も小さくなった場合を正確な端子高さ方向面512Hの寸法として特定する構成としたり、端子高さ方向面512Hがレーザー光Lと垂直となってはじめて受光器31Yがレーザー光Lを受光(ON)したり、遮断(OFF)したりする構成としてもよい。   For example, conversely, the case where the amount of light received by the light receiver 31Y is the smallest is specified as an accurate dimension of the terminal height direction surface 512H, or the terminal height direction surface 512H is perpendicular to the laser light L. Only when the light receiver 31Y receives the laser light L (ON) or shuts off (OFF) may be adopted.

上述した圧着形状検査装置1、及び、圧着形状検査方法によれば、以下の作用効果を奏することができる。
上述した圧着形状情報検査方法によれば、被覆電線520の導体露出部501に圧着した圧着後の圧着端子510の圧着形状に関する圧着形状情報を正確、且つ、容易に取得することができる。
According to the crimping shape inspection apparatus 1 and the crimping shape inspection method described above, the following operational effects can be achieved.
According to the above-described crimp shape information inspection method, the crimp shape information regarding the crimp shape of the crimp terminal 510 after crimping to the conductor exposed portion 501 of the covered electric wire 520 can be obtained accurately and easily.

詳しくは、モータ12により、圧着端子510を回転軸Z1回りに回転するに応じた導体圧着部531の投影形状情報を光学センサ31によって取得することができるため、例えば、導体圧着部531のボックス部511に対するローリング角度が任意に設定した閾値を超える結果となった圧着端子510を、不良品として判別することができる。   Specifically, since the optical sensor 31 can obtain the projection shape information of the conductor crimping part 531 according to the motor 12 rotating the crimping terminal 510 around the rotation axis Z1, for example, the box part of the conductor crimping part 531 The crimp terminal 510 that results in the rolling angle with respect to 511 exceeding the arbitrarily set threshold value can be determined as a defective product.

よって、導体露出部501を圧着端子510で圧着するに伴って生じる不具合の有無を検査することができる。   Accordingly, it is possible to inspect for the presence or absence of defects that occur when the conductor exposed portion 501 is crimped by the crimp terminal 510.

このように、人がゲージを用いて圧着端子510の各部寸法を測定することで圧着形状情報を取得する場合、測定誤差や、精度にばらつきが生じ易いが、このようなヒューマンエラーの影響を受けることがなく、精度よく、スムーズに圧着端子510の投影形状情報を取得することができる。   As described above, when a person acquires the crimp shape information by measuring the dimensions of each part of the crimp terminal 510 using a gauge, measurement errors and accuracy are likely to vary, but the human error is affected. The projection shape information of the crimp terminal 510 can be acquired accurately and smoothly.

さらに、導体圧着部531に投影したレーザー光Lを受光する際において、例えば、光学センサ31の基準箇所と圧着端子510の基準姿勢とを合わせるなどの手間を要することがなく、スムーズに圧着形状情報を取得できるとともに、例えば、基準箇所に合わせる際に生じる誤差の影響を受けることがないため、正確に所望のローリング角度を取得できる。   Furthermore, when receiving the laser beam L projected onto the conductor crimping portion 531, for example, it is possible to smoothly perform crimping shape information without the need for matching the reference position of the optical sensor 31 and the reference posture of the crimp terminal 510. Can be obtained, and for example, it is not affected by errors that occur when matching with the reference location, so that a desired rolling angle can be obtained accurately.

さらにまた、導体圧着部531に投影したレーザー光Lを受光するために、圧着端子510を押圧したり、切断するなどして破壊するなどの変形を伴うことがないため、別途、サンプルとしての余分な圧着端子510を作成する労力、コストを要することなく、圧着端子510の投影形状情報を取得することができる。   Furthermore, in order to receive the laser beam L projected onto the conductor crimping portion 531, there is no deformation such as pressing or cutting the crimping terminal 510 or breaking it. The projection shape information of the crimp terminal 510 can be acquired without requiring labor and cost for creating the proper crimp terminal 510.

また、上述した圧着形状情報検査方法によれば、エンコーダ11により、圧着端子510が回転する回転角度に関する回転角度情報を取得し、CPU52により、エンコーダ11で取得した回転角度情報と、光学センサ31で取得した受光量とを関連付け処理し、記憶部53により、関連付けた回転角度と受光量に関するデータを記憶する。   Further, according to the above-described crimp shape information inspection method, the encoder 11 acquires rotation angle information related to the rotation angle at which the crimp terminal 510 rotates, and the CPU 52 acquires the rotation angle information acquired by the encoder 11 and the optical sensor 31. The acquired received light amount is associated with each other, and the storage unit 53 stores data related to the associated rotation angle and received light amount.

このように、回転角度情報(回転角度)と投影形状情報(光量)とを関連付けすることにより、圧着端子510の軸方向の例えば、導体圧着部531において、端子軸方向回りにおける、いずれの角度において最も変形が生じているかを特定することが可能となる。   Thus, by associating the rotation angle information (rotation angle) with the projection shape information (light quantity), for example, in the conductor crimping portion 531 in the axial direction of the crimp terminal 510, at any angle around the terminal axis direction. It is possible to specify whether the deformation has occurred most.

よって、変形が生じた不具合箇所を迅速、且つ正確に特定することができ、例えば、不具合箇所の矯正、不具合箇所の傾向を解明、或いは、不具合が生じる原因究明といった対策を容易に施すことができる。   Therefore, it is possible to quickly and accurately identify the defect location where the deformation has occurred, and for example, it is possible to easily take measures such as correcting the failure location, elucidating the tendency of the failure location, or investigating the cause of the failure. .

また、上述した圧着形状情報検査方法によれば、端子保持具14により、圧着端子510を保持した状態で端子軸方向回りに回転させることができるため、光学センサ31を端子軸方向回りに回転させる場合と比較して、小さな回転半径で端子軸方向回りに回転させることができるため、端子回転ユニット10の構成をシンプルな構成とすることができるとともに、少ないエネルギーでスムーズに回転させることができる。   Further, according to the above-described crimp shape information inspection method, the terminal holder 14 can be rotated around the terminal axis direction while the crimp terminal 510 is held, so the optical sensor 31 is rotated around the terminal axis direction. Compared to the case, since it can be rotated around the terminal axis direction with a small turning radius, the configuration of the terminal rotating unit 10 can be made simple and can be rotated smoothly with less energy.

圧着形状情報取得方法によれば、光学センサ31を構成する投光器31Xにより、前記形状情報取得対象箇所に向けて投光し、光学センサ31を構成する受光器31Yにより、該投光器31Xのレーザー光Lの投光により投影した投影形状に基づく投影形状情報としてのレーザー光Lを受光する。   According to the pressure bonding shape information acquisition method, light is projected toward the shape information acquisition target portion by the projector 31X constituting the optical sensor 31, and the laser light L of the projector 31X is received by the light receiver 31Y constituting the optical sensor 31. The laser beam L is received as projection shape information based on the projection shape projected by the projection.

上述した構成によれば、投光器31Xが投光したレーザー光Lによって投影した投影形状に基づくレーザー光Lを受光器31Yで受光することで圧着形状情報を取得するため、例えば、CCDカメラを用いる場合のように、高価な装置や複雑なシステムを必要とせずに、簡素な構成によってレーザー光Lを投影形状情報として確実に取得できる。   According to the above-described configuration, for example, when using a CCD camera, the laser light L based on the projected shape projected by the laser light L projected by the light projector 31X is received by the light receiver 31Y to acquire the crimping shape information. As described above, the laser light L can be reliably acquired as projection shape information with a simple configuration without requiring an expensive apparatus or a complicated system.

圧着形状情報取得方法によれば、導体圧着部531と光学センサ31とが対向する対向方向に直交し、且つ、前記端子軸方向に直交する方向を直交方向に設定し、導体圧着部531を投影した投影箇所における、前記直交方向の寸法に関する投影直交寸法情報Lに設定し、圧着端子510の光学センサ31に対する相対回転に伴って、導体圧着部531を投影したレーザー光Lを受光した受光器31Yの受光量が変化するが、この受光量が最大となるとき、すなわち、導体圧着部531における投影直交寸法Lの最小となるとき、その最小値を、導体圧着部531の高さ寸法、又は、幅寸法として特定できる。   According to the crimping shape information acquisition method, the conductor crimping part 531 and the optical sensor 31 are orthogonal to the facing direction, and the direction perpendicular to the terminal axis direction is set to the orthogonal direction, and the conductor crimping part 531 is projected. The light receiving device 31Y that has received the laser light L projected on the conductor crimping portion 531 in accordance with the relative rotation of the crimping terminal 510 with respect to the optical sensor 31 is set to the projection orthogonal dimension information L regarding the dimension in the orthogonal direction at the projected position. However, when the amount of received light is maximized, that is, when the projected orthogonal dimension L of the conductor crimping portion 531 is minimum, the minimum value is set to the height dimension of the conductor crimping portion 531 or It can be specified as a width dimension.

従って、導体圧着部531がローリング変形しているか否かに関わらず、導体圧着部531の高さ寸法、又は、幅寸法を計測できる。   Therefore, the height dimension or the width dimension of the conductor crimping portion 531 can be measured regardless of whether the conductor crimping portion 531 is rolling-deformed.

続いて、上述した実施形態における圧着形状検査装置1を用いた他の圧着形状検査方法について図6(a),(b),(c),(d)、及び図7を用いて説明する。
まず、図6(a)に示すように、圧着端子510を前記基準姿勢に対して時計回りR2に5度傾いた姿勢となるよう回転させる。
Next, another crimping shape inspection method using the crimping shape inspection apparatus 1 in the above-described embodiment will be described with reference to FIGS. 6 (a), (b), (c), (d), and FIG.
First, as shown in FIG. 6A, the crimp terminal 510 is rotated so as to be in a posture inclined 5 degrees clockwise R2 with respect to the reference posture.

そのこの姿勢を初期姿勢として、圧着端子510を初期姿勢に対して反時計回りR1に約100度程度回転させ、図6(d)に示すような姿勢とする。   With this posture as an initial posture, the crimp terminal 510 is rotated about 100 degrees counterclockwise R1 with respect to the initial posture to obtain a posture as shown in FIG.

圧着端子510を回転させている間、図6(b)に示すように、投光器31Xから投光されるレーザー光Lを、形状情報取得対象箇所としての導体圧着部531に投光するとともに、図6(c)に示すように、導体圧着部531の投影形状に基づく投影形状情報を受光量として受光器31Yにより受光する。   While rotating the crimp terminal 510, as shown in FIG. 6 (b), the laser light L projected from the projector 31X is projected onto the conductor crimping portion 531 as the shape information acquisition target location. As shown in FIG. 6C, the light receiver 31Y receives the projection shape information based on the projection shape of the conductor crimping portion 531 as the amount of received light.

圧着端子510の投光器31Xに対する角度(姿勢)に応じて、受光器31Yで受光する受光量が変化する。そして、図7に示すように、導体圧着部531の端子高さ方向面512Hがレーザー光Lの進む方向に対して垂直になるに連れて受光器31Yにより受光する受光量が大きくなっていき、図6(b)に示すように、端子高さ方向面512Hがレーザー光Lの進む方向に対して垂直になったときに一度目の最大値(Y1)として第1最大点M1を迎える。   The amount of light received by the light receiver 31Y changes according to the angle (posture) of the crimp terminal 510 with respect to the projector 31X. As shown in FIG. 7, as the terminal height direction surface 512H of the conductor crimping portion 531 becomes perpendicular to the direction in which the laser light L travels, the amount of light received by the light receiver 31Y increases. As shown in FIG. 6B, when the terminal height direction surface 512H is perpendicular to the direction in which the laser light L travels, the first maximum point M1 is reached as the first maximum value (Y1).

そして、続けて回転するに従って、受光器31Yで受光する受光量が徐々に減少していくが、やがて図6(c)に示すように、端子幅方向面512Wがレーザー光Lの進む方向に対して垂直になったときに2度目の最大値(α2)として第2最大点M2を迎え、最終的に100度程度回転するまで受光量が降下していく。   As the rotation continues, the amount of light received by the light receiver 31Y gradually decreases. Eventually, the terminal width direction surface 512W moves in the direction in which the laser light L travels as shown in FIG. Then, the second maximum point M2 is reached as the second maximum value (α2) when it becomes vertical, and the amount of received light decreases until it finally rotates about 100 degrees.

このように、圧着端子510を回転する間において、回転角度と受光量との関係は、図7に示すような傾向が生じことになる。   Thus, during the rotation of the crimp terminal 510, the relationship between the rotation angle and the amount of received light tends to be as shown in FIG.

そして、上述したように、受光量と端子高さ方向面512Hの寸法との関係を示す記憶部53に記憶されたデータを基にして、第1最大点M1における受光量から、正確な端子高さ方向面512Hの寸法、すなわち、導体圧着部531の高さ寸法を特定することができる。   Then, as described above, based on the data stored in the storage unit 53 indicating the relationship between the received light amount and the dimension of the terminal height direction surface 512H, the accurate terminal height is determined from the received light amount at the first maximum point M1. The dimension of the lateral surface 512H, that is, the height dimension of the conductor crimping portion 531 can be specified.

さらに、第2最大点M2における受光量から、正確な端子幅方向面512Wの寸法、すなわち、導体圧着部531の幅寸法を特定することができる。   Furthermore, the exact dimension of the terminal width direction surface 512W, that is, the width dimension of the conductor crimping portion 531 can be specified from the amount of light received at the second maximum point M2.

よって、上述した圧着端子510の端子幅方向面512Wの直交寸法、及び、ローリング角度の計測のみならず、圧着端子510の端子幅方向面512Wの直交寸法と、端子高さ方向面512Hの直交寸法とを同時に計測することができる。   Accordingly, the orthogonal dimension of the terminal width direction surface 512W of the crimp terminal 510 and the measurement of the rolling angle as well as the orthogonal dimension of the terminal width direction surface 512W of the crimp terminal 510 and the orthogonal dimension of the terminal height direction surface 512H are described above. Can be measured simultaneously.

従って、上述した圧着形状検査方法によれば、圧着端子510を端子軸回りに90度以上の所定の角度範囲で相対回転させるという一度の回転動作によって、導体圧着部531の幅寸法と高さ寸法との双方の寸法を取得できる。   Therefore, according to the above-described crimped shape inspection method, the width dimension and the height dimension of the conductor crimping portion 531 are achieved by a single rotation operation in which the crimping terminal 510 is relatively rotated around the terminal axis within a predetermined angle range of 90 degrees or more. And both dimensions can be acquired.

さらに、上述したように、回転角度情報と投影形状情報とを関連付けた関連付けデータを基にして、第1最大点M1、又は、第2最大点M2における圧着端子510の回転角度から圧着端子510のローリング角度(α)を特定することもできる。   Furthermore, as described above, based on the association data in which the rotation angle information and the projection shape information are associated with each other, the crimp terminal 510 is determined based on the rotation angle of the crimp terminal 510 at the first maximum point M1 or the second maximum point M2. The rolling angle (α) can also be specified.

上述した構成によれば、被覆電線520に対して端子軸方向回りにローリング変形した導体圧着部531のローリング角度を測定するに際して、従来のように、端子軸方向に対して直交する直交断面があらわれるよう圧着端子510を切断する必要がなく、非破壊で導体圧着部531のローリング角度を測定することができる。   According to the configuration described above, when measuring the rolling angle of the conductor crimping portion 531 that is rolled and deformed around the terminal axis direction with respect to the covered electric wire 520, an orthogonal cross section orthogonal to the terminal axis direction appears as in the past. Thus, it is not necessary to cut the crimping terminal 510, and the rolling angle of the conductor crimping part 531 can be measured in a nondestructive manner.

また、上述した圧着形状検査方法によれば、圧着端子510を回転する間に、圧着端子510の端子高さ方向面512H、或いは、端子幅方向面512Wが投光器31Xと対向する姿勢が含まれるように回転させると、回転角度と光量との関係を示すグラフ中に、図7に示すように、第1最大点M1と第2最大点M2とが表れることになる。このため、圧着端子510の端子高さ方向面512H、或いは、端子幅方向面512Wが投光器31Xと対向する姿勢が含まれる回転である限り、圧着端子510の回転の初期位置、回転方向、回転角度は特に限定しない。   Further, according to the above-described crimped shape inspection method, the terminal height direction surface 512H or the terminal width direction surface 512W of the crimp terminal 510 is included in the posture facing the projector 31X while the crimp terminal 510 is rotated. As shown in FIG. 7, the first maximum point M1 and the second maximum point M2 appear in the graph showing the relationship between the rotation angle and the light amount.
