Description

試験装置、試験方法および組立ラインTest equipment, test method and assembly line
　本発明は、電気器具の電気性能試験を実施する試験装置、試験方法および組立ラインに関する。 The present invention relates to a test device, a test method, and an assembly line for performing an electrical performance test of an electric appliance.
　コネクタとは、電線と電線、または電線と電気器具とを接続するための部品であり、外部との電気的接続を必要とする電気器具には必ず搭載されている部品である。コネクタの種類は複数存在するが、電気器具に広く用いられるコネクタとして汎用的な通信規格であるＵＳＢ（Universal　Serial　Bus）、またはＥｔｈｅｒｎｅｔ（登録商標）、ＩＳＤＮ（Integrated　Services　Digital　Network）などのケーブルを接続するために用いられるモジュラープラグの規格であるＲＪ（Registered　Jack）－４５などが挙げられる。 A connector is a component for connecting an electric wire to an electric wire or an electric wire to an electric appliance, and is a component that is always installed in an electric appliance that requires an electrical connection with the outside. There are multiple types of connectors, but cables such as USB (Universal Serial Bus), which is a general-purpose communication standard widely used for electrical appliances, Ethernet (registered trademark), and ISDN (Integrated Services Digital Network) are connected. RJ (Registered Jack) -45, which is a standard for modular plugs used for this purpose, can be mentioned.
　電気器具の電気性能試験を実施するためには試験装置と電気器具とを電気的に接続させる必要があるが、電気器具の多機能化に伴い、電気器具に搭載されるコネクタの数および種類は増加する傾向にある。コネクタの数の増加に伴い、試験装置と電気器具とを電気的に接続させる際、人手によってコネクタを挿抜する方法は、作業時間が増加し、生産効率が低下する。また、コネクタの挿入量不十分による試験装置と電気器具との電気的接触不良、コネクタの誤挿入などによって、本来試験に合格すべき電気器具が不良と判断される場合がある。複数のコネクタを簡便かつ確実に嵌合して電気的に接続する方法が、電気性能試験の作業効率化に求められている。 In order to carry out an electrical performance test of an electric appliance, it is necessary to electrically connect the test device and the electric appliance. It tends to increase. As the number of connectors increases, the method of manually inserting and removing the connectors when electrically connecting the test device and the electric appliance increases the working time and reduces the production efficiency. In addition, an electric appliance that should originally pass the test may be judged to be defective due to poor electrical contact between the test device and the electric appliance due to insufficient insertion amount of the connector, incorrect insertion of the connector, and the like. A method of easily and surely fitting a plurality of connectors and electrically connecting them is required to improve the work efficiency of an electrical performance test.
　特許文献１には、複数のコネクタが取り付けられた連動フレーム、および連動フレームを動作させる操作レバーからなるコネクタ同時挿入機構を備え、操作レバーを操作することで、カードが有する複数のコネクタと連動フレームに取り付けられた複数のコネクタとを同時に嵌合させる技術が開示されている。 Patent Document 1 includes an interlocking frame to which a plurality of connectors are attached, and a connector simultaneous insertion mechanism including an operation lever for operating the interlocking frame. By operating the operation lever, a plurality of connectors of the card and the interlocking frame are provided. A technique for simultaneously fitting a plurality of connectors attached to a device is disclosed.
特開２００１－２４４０３３号公報Japanese Unexamined Patent Publication No. 2001-244033
　しかしながら、特許文献１に記載の技術によれば、コネクタ同時挿入機構は、電気器具で使用されることから、頻繁に操作されることは想定されていない。製品組み立てラインで使用される試験装置は、大量生産される電気器具を対象にして数十秒間隔でコネクタを挿抜する必要がある。そのため、特許文献１に記載のコネクタ同時挿入機構を試験装置に適用しても、劣化が早く耐久性が低い、という問題があった。また、特許文献１に記載の技術によれば、コネクタ同時挿入機構は、連動フレームの挿抜穴に各コネクタの外部に設けられたピンを嵌め込むことで複数のコネクタの動きを連動させる構成である。そのため、各コネクタにおいてがたつきが生じる可能性がある、という問題があった。 However, according to the technique described in Patent Document 1, since the connector simultaneous insertion mechanism is used in electric appliances, it is not assumed that it is frequently operated. The test equipment used in the product assembly line requires the connector to be inserted and removed at intervals of several tens of seconds for mass-produced electric appliances. Therefore, even if the connector simultaneous insertion mechanism described in Patent Document 1 is applied to the test apparatus, there is a problem that the deterioration is fast and the durability is low. Further, according to the technique described in Patent Document 1, the connector simultaneous insertion mechanism has a configuration in which the movements of a plurality of connectors are interlocked by fitting pins provided outside each connector into the insertion / extraction holes of the interlocking frame. .. Therefore, there is a problem that rattling may occur in each connector.

　上述した課題を解決し、目的を達成するために、本発明は、電気器具が有する複数の第１のコネクタに嵌合する複数の第２のコネクタを有する試験装置である。試験装置は、複数の第２のコネクタの各々を把持するコネクタ把持部、コネクタ把持部を把持する挿抜冶具部、電気器具の外装を把持して電気器具の位置決めをする外装把持部、および、挿抜冶具部を外装把持部の方向である第１の方向および第１の方向と反対方向である第２の方向に移動可能な駆動部、を備えるコネクタ挿抜冶具を備える。また、試験装置は、駆動部に動力を供給する動力部と、電気器具が外装把持部に搬入されると、動力部を制御して駆動部を動作させ、複数の第２のコネクタと複数の第１のコネクタとを嵌合させて電気器具と電気的に接続し、電気器具に対して、複数の第２のコネクタを介して、電気性能試験を行うための第１の電気信号を送出し、電気器具から送出される第２の電気信号を取得して検査する制御部と、を備えることを特徴とする。 In order to solve the above-mentioned problems and achieve the object, the present invention is a test apparatus having a plurality of second connectors that are fitted to a plurality of first connectors of an electric appliance. The test device includes a connector grip portion that grips each of the plurality of second connectors, an insertion / extraction jig portion that grips the connector grip portion, an exterior grip portion that grips the exterior of the electric appliance to position the electric appliance, and an insertion / extraction. The connector insertion / removal jig is provided with a drive unit that can move the jig unit in a first direction that is the direction of the exterior grip portion and a second direction that is opposite to the first direction. Further, the test device has a power unit that supplies power to the drive unit, and when the electric appliance is carried into the exterior grip portion, the test device controls the power unit to operate the drive unit, and has a plurality of second connectors and a plurality of. The first connector is fitted and electrically connected to the electric appliance, and a first electric signal for performing an electric performance test is sent to the electric appliance through a plurality of second connectors. It is characterized by including a control unit that acquires and inspects a second electric signal transmitted from the electric appliance.
　本発明によれば、試験装置は、電気器具が備える複数のコネクタと簡便かつ確実に嵌合できる、という効果を奏する。 According to the present invention, the test apparatus has an effect that it can be easily and surely fitted to a plurality of connectors included in an electric appliance.

　つづいて、試験装置１００の動作について説明する。図７は、実施の形態１に係る試験装置１００が電気性能試験を実施する動作を示すフローチャートである。まず、試験装置１００の外装把持部１に電気器具３００が搬入される（ステップＳ１）。電気器具３００は、図示しない外部の搬送装置によって外装把持部１に搬入されてもよいし、作業者などの人手によって外装把持部１に搬入されてもよい。外装把持部１は、電気器具３００の電気器具外装部４を把持して電気器具３００の位置決めをする。制御部１０１は、外装把持部１に搬入された電気器具３００が規定された位置に固定されていることを検出する（ステップＳ２）。制御部１０１は、図示しない固定カメラ、圧力センサ、レーザー検出器などを用いることで、外装把持部１が固定されていることを検出することができる。 Next, the operation of the test device 100 will be described. FIG. 7 is a flowchart showing an operation in which the test apparatus 100 according to the first embodiment performs an electrical performance test. First, the electric appliance 300 is carried into the exterior grip portion 1 of the test apparatus 100 (step S1). The electric appliance 300 may be carried into the exterior grip portion 1 by an external transfer device (not shown), or may be carried into the exterior grip portion 1 by a manual worker or the like. The exterior grip portion 1 grips the electric appliance exterior portion 4 of the electric appliance 300 to position the electric appliance 300. The control unit 101 detects that the electric appliance 300 carried into the exterior grip unit 1 is fixed at a specified position (step S2). The control unit 101 can detect that the exterior grip portion 1 is fixed by using a fixed camera, a pressure sensor, a laser detector, or the like (not shown).
　駆動部３は、挿抜冶具部２を第１の方向に移動させて、複数の試験用コネクタ７を電気器具３００の複数の電気器具搭載コネクタ６に嵌合させる。具体的には、制御部１０１は、電気器具３００が外装把持部１に搬入されると、動力部１０２を介して、コネクタ挿抜冶具２００の駆動部３を動作させ、試験用コネクタ７を電気器具３００の電気器具搭載コネクタ６へと接近させる。コネクタ挿抜冶具２００は、試験用コネクタ７が電気器具搭載コネクタ６に接触した場合、第１の可動部８および第２の可動部９によって、電気器具搭載コネクタ６の外形に倣いながら試験用コネクタ７と電気器具搭載コネクタ６とを嵌合、すなわち試験用コネクタ７を電気器具搭載コネクタ６に挿入する（ステップＳ３）。このとき、コネクタ挿抜冶具２００は、複数の試験用コネクタ７を複数の電気器具搭載コネクタ６に同時に嵌合させる。制御部１０１は、図示しない固定カメラ、圧力センサ、レーザー検出器などを用いることで、コネクタ同士が確実に嵌合していることを確認できる。 The drive unit 3 moves the insertion / extraction jig 2 in the first direction to fit the plurality of test connectors 7 into the plurality of electric appliance mounting connectors 6 of the electric appliance 300. Specifically, when the electric appliance 300 is carried into the exterior grip portion 1, the control unit 101 operates the drive unit 3 of the connector insertion / extraction jig 200 via the power unit 102, and makes the test connector 7 the electric appliance. Bring it closer to the 300 appliance mounting connector 6. When the test connector 7 comes into contact with the electric appliance mounting connector 6, the connector insertion / extraction jig 200 uses the first movable portion 8 and the second movable portion 9 to follow the outer shape of the electric appliance mounting connector 6 and to follow the outer shape of the electric appliance mounting connector 6. And the electric appliance mounting connector 6 are fitted, that is, the test connector 7 is inserted into the electric appliance mounting connector 6 (step S3). At this time, the connector insertion / extraction jig 200 simultaneously fits the plurality of test connectors 7 into the plurality of electric appliance mounting connectors 6. The control unit 101 can confirm that the connectors are securely fitted to each other by using a fixed camera, a pressure sensor, a laser detector, or the like (not shown).
　制御部１０１は、電気器具３００に対して、試験用コネクタ７を介して、電気器具３００を動作させることができる第１の電気信号を送出し、電気性能試験を開始する（ステップＳ４）。制御部１０１は、電気器具３００が第１の電気信号を受け取ることで送出する第２の電気信号を取得して、第２の電気信号を検査することで電気性能試験を実施する。制御部１０１は、電気性能試験の項目に応じて、第１の電気信号の送出と、第２の電気信号の検査とを繰り返し実施する。なお、制御部１０１は、第１の電気信号の送出と、第２の電気信号の検査とを自動で実施することができるものとする。 The control unit 101 sends a first electric signal capable of operating the electric appliance 300 to the electric appliance 300 via the test connector 7 and starts an electric performance test (step S4). The control unit 101 acquires a second electric signal transmitted by the electric appliance 300 when it receives the first electric signal, and inspects the second electric signal to carry out an electric performance test. The control unit 101 repeatedly executes the transmission of the first electric signal and the inspection of the second electric signal according to the items of the electric performance test. The control unit 101 can automatically send out the first electric signal and inspect the second electric signal.
　制御部１０１において電気性能試験が終了すると（ステップＳ５）、駆動部３は、挿抜冶具部２を第２の方向に移動させて、複数の試験用コネクタ７と複数の電気器具搭載コネクタ６とを分離させる。具体的には、制御部１０１は、動力部１０２を介して、コネクタ挿抜冶具２００の駆動部３を動作させ、試験用コネクタ７と電気器具３００の電気器具搭載コネクタ６とを分離させる。すなわち、制御部１０１は、電気器具３００の電気器具搭載コネクタ６から試験用コネクタ７を抜去する（ステップＳ６）。制御部１０１は、外部の搬送装置または作業者へ電気性能試験が完了したことを通知する（ステップＳ７）。制御部１０１は、通知相手が外部の搬送装置の場合は外部の搬送装置が受け取ることができる形式の電気信号で通知を行い、通知相手が作業者の場合は光、音など、すなわち視覚、聴覚などの情報で通知する。試験装置１００では、外装把持部１から電気器具３００が搬出される（ステップＳ８）。電気器具３００は、外部の搬送装置によって外装把持部１から搬出されてもよいし、作業者などの人手によって外装把持部１から搬出されてもよい。 When the electrical performance test is completed in the control unit 101 (step S5), the drive unit 3 moves the insertion / extraction jig 2 in the second direction to connect the plurality of test connectors 7 and the plurality of electric appliance mounting connectors 6. Separate. Specifically, the control unit 101 operates the drive unit 3 of the connector insertion / extraction jig 200 via the power unit 102 to separate the test connector 7 and the electric appliance mounting connector 6 of the electric appliance 300. That is, the control unit 101 removes the test connector 7 from the electric appliance mounting connector 6 of the electric appliance 300 (step S6). The control unit 101 notifies the external transfer device or the operator that the electrical performance test has been completed (step S7). The control unit 101 notifies by an electric signal in a format that can be received by the external transport device when the notification partner is an external transport device, and when the notification partner is an operator, light, sound, etc., that is, visual and auditory senses. Notify with information such as. In the test device 100, the electric appliance 300 is carried out from the exterior grip portion 1 (step S8). The electric appliance 300 may be carried out from the exterior grip portion 1 by an external transport device, or may be carried out from the exterior grip portion 1 by a manual worker or the like.
　このように、試験装置１００は、電気器具３００が搬入されてから搬出されるまでの電気性能試験を、人手を介さずに自動化して実施することができる。 In this way, the test device 100 can automate the electrical performance test from the time the electric appliance 300 is carried in to the time it is carried out without human intervention.

　位置決めピン３１は、挿抜冶具部２の下部に設けられる平面方向に任意の形状を持つ柱状のピンである。位置決めピン３１の形状は、例えば、平面方向に円形状であれば円柱または円錐の形状となり、平面方向に四角形であれば四角柱または四角推の形状となる。挿抜冶具部２が外装把持部１ａへと接近した際、位置決めピン３１は、外装把持部１ａに設けられた位置決めピン３１が挿入可能な穴へと挿入される。これにより、コネクタ挿抜冶具２００ａは、外装把持部１ａに対する挿抜冶具部２の位置を精度よく粗調整することができる。ここで、位置決めピン３１と外装把持部１ａに設けられた穴とが初めに接触する部分には、Ｃ面取りを行うなど双方に傾斜形状をつけておくことが望ましい。 The positioning pin 31 is a columnar pin provided in the lower part of the insertion / extraction jig 2 and having an arbitrary shape in the plane direction. The shape of the positioning pin 31 is, for example, a cylinder or a cone if it is circular in the plane direction, and a quadrangular prism or a square thruster if it is square in the plane direction. When the insertion / extraction jig 2 approaches the exterior grip portion 1a, the positioning pin 31 is inserted into a hole into which the positioning pin 31 provided in the exterior grip portion 1a can be inserted. As a result, the connector insertion / extraction jig 200a can accurately and roughly adjust the position of the insertion / extraction jig 2 with respect to the exterior grip portion 1a. Here, it is desirable that the portion where the positioning pin 31 and the hole provided in the exterior grip portion 1a first come into contact with each other is provided with an inclined shape such as by performing C chamfering.
　挿入ガイド３２は、コネクタ把持部１０の下部に設けられる内側に傾斜形状を持ったガイドである。挿抜冶具部２が外装把持部１ａへと接近した際、挿入ガイド３２は、電気器具外装部４の外形に沿ってコネクタ把持部１０へと外的な力を加える。この結果、第２の可動部９は、コネクタ把持部１０の位置を変位させることができる。これにより、コネクタ挿抜冶具２００ａは、試験用コネクタ７が電気器具搭載コネクタ６と接触する前に、電気器具外装部４とコネクタ把持部１０との位置を精度よく微調整することが可能となる。 The insertion guide 32 is a guide having an inclined shape inside provided at the lower part of the connector grip portion 10. When the insertion / extraction jig 2 approaches the exterior grip 1a, the insertion guide 32 applies an external force to the connector grip 10 along the outer shape of the electrical appliance exterior 4. As a result, the second movable portion 9 can displace the position of the connector grip portion 10. As a result, the connector insertion / extraction jig 200a can accurately finely adjust the positions of the electric appliance exterior portion 4 and the connector grip portion 10 before the test connector 7 comes into contact with the electric appliance mounting connector 6.
　以上説明したように、本実施の形態によれば、コネクタ挿抜冶具２００ａは、位置決めピン３１および挿入ガイド３２を備えることで、実施の形態１のコネクタ挿抜冶具２００と比較して、より高精度に試験用コネクタ７を電気器具搭載コネクタ６へと挿入することができる。 As described above, according to the present embodiment, the connector insertion / extraction jig 200a is provided with the positioning pin 31 and the insertion guide 32, so that the connector insertion / extraction jig 200a has higher accuracy than the connector insertion / extraction jig 200 of the first embodiment. The test connector 7 can be inserted into the electric appliance mounting connector 6.
