しかしながら、前述した電気検査装置では、検査用プローブが取り付けられる場所に応じて圧力センサの取り付け位置も変更しなければならないため、取付操作が面倒になったり、各部材にそれぞれ圧力センサを設ける必要が生じたりするという問題がある。また、検査用プローブが取り付けられる取付部材に圧力センサを設けた電気検査装置もあるが、これによると、複数の検査用プローブを取り替えながら使用する場合には、各取付部材にそれぞれセンサを設けなければならなくなりコストが高くなるという問題が生じる。   However, in the electrical inspection apparatus described above, the mounting position of the pressure sensor has to be changed depending on the location where the inspection probe is mounted. Therefore, the mounting operation becomes troublesome and it is necessary to provide a pressure sensor for each member. There is a problem that occurs. In addition, there is an electrical inspection device in which a pressure sensor is provided on an attachment member to which an inspection probe is attached. According to this, when using a plurality of inspection probes while replacing them, each attachment member must be provided with a sensor. There is a problem that the cost becomes higher due to the necessity.

本発明は、前述した問題に対処するためになされたもので、その目的は、検査用プローブとともに取付部材を取り替えても共通の検出装置を用いることができるため、検出装置の取り替えが不要で安価につくプリント基板の電気検査装置および電気検査方法を提供することである。   The present invention has been made in order to cope with the above-described problems. The object of the present invention is to eliminate the need for replacement of the detection device because the common detection device can be used even if the mounting member is replaced with the inspection probe. It is an object to provide an electrical inspection apparatus and electrical inspection method for printed circuit boards.

前述した目的を達成するため、本発明に係るプリント基板の電気検査装置の構成上の特徴は、設置装置に設置されたプリント基板の接点に検査用プローブを接触させることにより、プリント基板の電気検査を行うプリント基板の電気検査装置であって、検査用プローブが取り付けられる取付部材と、取付部材を設置装置に設置されたプリント基板に対して進退させることにより、検査用プローブをプリント基板に接触させるモータを備えた駆動装置と、駆動装置のモータに接続され、検査用プローブがプリント基板に接触したときに、プリント基板に対する検査用プローブの押圧力を駆動装置に掛かる反力として検出する検出装置と、検査用プローブの種類、個数および配置に基づいて検査用プローブの押圧力の適正値を求め、検出装置が検出した検査用プローブのプリント基板に対する押圧力が適正値になるように駆動装置の駆動を制御する制御装置とを備えたことにある。 In order to achieve the above-mentioned object, the structural feature of the electrical inspection apparatus for a printed circuit board according to the present invention is that electrical inspection of the printed circuit board is performed by bringing an inspection probe into contact with a contact of the printed circuit board installed in the installation apparatus. An electrical inspection device for a printed circuit board, wherein the inspection probe is brought into contact with the printed circuit board by advancing and retracting the mounting member to which the inspection probe is mounted and the printed circuit board installed in the installation device. a drive moving device provided with a motor that is connected to a motor drive equipment, when the inspection probe is brought into contact with the printed circuit board, for detecting the pressing force of the inspection probe to the printed circuit board as a reaction force on the drive unit a detection device, obtains the proper value of the pressing force of the test probe on the basis of the type of test probe, the number number and placement detection devices tested In that a control device for controlling the driving of the driving device so pressing force becomes a proper value for the printed circuit board inspection probe.

前述したように構成した本発明に係るプリント基板の電気検査装置では、プリント基板に対する検査用プローブの押圧力を検出する検出装置が、検査用プローブや検査用プローブが取り付けられる取付部材でなく、駆動装置に掛かる反力として前記押圧力を検出するように構成されている。このため、検出装置は、駆動装置または駆動装置に接続した状態で駆動装置の外部に設置することができる。この結果、電気検査の目的に応じて検査用プローブを取付部材とともに取り替えた場合でも、検出装置は駆動装置に掛かる反力を元の状態のままで検出できるようになり、検出装置の取り替えが不要になる。また、制御装置による駆動装置の駆動制御により、検査用プローブは接点に対して適正な押圧力で接触するようになるため、接触不良がなくなり精度のよい電気検査が行える。 In the electrical inspection apparatus for a printed circuit board according to the present invention configured as described above, the detection device for detecting the pressing force of the inspection probe against the printed circuit board is not a mounting member to which the inspection probe or the inspection probe is attached, but a driving device. The pressing force is detected as a reaction force applied to the moving device. For this reason, a detection apparatus can be installed in the exterior of a drive device in the state connected to the drive device or the drive device. As a result, even when the inspection probe is replaced with the mounting member according to the purpose of the electrical inspection, the detection device can detect the reaction force applied to the drive device as it is, and the detection device does not need to be replaced. become. In addition, since the inspection probe comes into contact with the contact with an appropriate pressing force by the drive control of the drive device by the control device, there is no contact failure, and an accurate electrical inspection can be performed.

In this case, the detection device moves the mounting member to the printed circuit board side by driving the driving device, and when the inspection probe contacts the printed circuit board and presses the printed circuit board, the inspection probe and the mounting member are moved from the printed circuit board. The reaction force applied to the drive device via the is detected. Therefore, it is not necessary to provide the detection device in the vicinity of the inspection probe or the mounting member, and the degree of freedom increases in the installation position of the detection device.

In this case, the detection device is provided in the support portion, and when the motor is driven, the attachment member is moved to the printed circuit board side, and when the inspection probe contacts the printed circuit board and presses the printed circuit board, the inspection device is inspected from the printed circuit board. The reaction force applied to the support portion of the drive device is detected through the probe and the mounting member. The mounting member is, when replacing the inspection probe is removed support part side or al, the detection device because it is provided in the support portion, can be used without replacing it.

本発明に係るプリント基板の電気検査方法の構成上の特徴は、検査用プローブが取り付けられた取付部材をプリント基板に対して進退させることにより、検査用プローブをプリント基板に所定の押圧力で接触させるモータを備えた駆動装置と、駆動装置のモータに接続された検出装置とを用いて、プリント基板の電気検査を行うプリント基板の電気検査方法であって、検査用プローブをプリント基板に接触させる接触工程と、検査用プローブがプリント基板に接触したときに、検出装置が、プリント基板に対する検査用プローブの押圧力を駆動装置に掛かる反力として検出する反力検出工程と、検査用プローブの種類、個数および配置に基づいて検査用プローブの押圧力の適正値を求め、反力検出工程において検出された検査用プローブのプリント基板に対する押圧力が適正値になるように駆動装置の駆動を制御する押圧力制御工程とを備えたことにある。 The structural feature of the electrical inspection method for a printed circuit board according to the present invention is that the inspection probe is brought into contact with the printed circuit board with a predetermined pressing force by advancing and retracting the mounting member to which the inspection probe is mounted. a drive moving device provided with a motor that causes Ru is, by using the connected detector to a motor drive equipment, an electrical inspection method of a printed circuit board for electrically testing printed circuit board, printed circuit board inspection probe A contact process for contact with the printed circuit board, a reaction force detection process for detecting a pressing force of the test probe against the printed circuit board as a reaction force applied to the drive device when the inspection probe contacts the printed circuit board, types of probes, number count and determine the proper value of the pressing force of the test probe on the basis of the placement, the inspection probe is detected in the reaction force detecting step flop In that a pressing force control step of controlling the driving of the driving device so pressing force becomes a proper value for the cement board.

これによると、検査用プローブを取り替えても検出装置を取り替える必要のないプリント基板の電気検査方法を安価でかつ精度よく実施できる。この場合、反力検出工程において検出される駆動装置に掛かる反力が駆動装置の駆動力に対して掛かる反力であるとすることができる。また、駆動装置が前記取付部材を前記駆動装置側に着脱可能に取り付けるための支持部を備え、反力検出工程において検出される駆動装置に掛かる反力が、支持部に掛かる反力であるとすることもできる。
According to this, even if the inspection probe is replaced, the printed circuit board electrical inspection method that does not require replacement of the detection device can be performed at low cost and with high accuracy. In this case, the reaction force applied to the drive device detected in the reaction force detection step can be regarded as the reaction force applied to the drive force of the drive device. Further , the drive device includes a support portion for detachably attaching the attachment member to the drive device side, and the reaction force applied to the drive device detected in the reaction force detection step is a reaction force applied to the support portion.

Various devices such as the moving devices 15 and 18, the moving devices 16 and 19, and the motors 32 and 42 are controlled by various controls by the program execution of the CPU 51, and the detection units 37 and 47 are moved to predetermined positions by this control. . Further, the RAM 53 stores the pressure calculation data 53a shown in FIG. 6 in advance.

As a distribution in this case, for example, Pa is a distribution state in which the inspection probes 36 and 46 are arranged in the detection units 37 and 47 with substantially equal intervals, and Pb is an inspection probe 36 or 46. Is distributed in a large amount in the central portion of the detection units 37 and 47 and is disposed in a small amount in the outer peripheral portion, and Pc is a small number of inspection probes 36 and 46 are disposed in the central portion of the detection units 37 and 47. It is assumed that there are many distributed states on the side portion.

そして、これらの各データから押圧力の適正値を求め、その押圧力を出力するために必要なモータ電流値を決定できるようにした。また、検査回路５４は、検査用プローブ３６，４６とプリント基板１１の接点１１ａとの導通状態を検出してその検出結果を信号として制御装置５０に送信する。さらに、操作盤には、電気検査装置１０をオンオフするためのスイッチや各種のデータを入力するための操作キー等が設けられている。   Then, an appropriate value of the pressing force is obtained from each of these data, and the motor current value necessary for outputting the pressing force can be determined. Further, the inspection circuit 54 detects the conduction state between the inspection probes 36 and 46 and the contact 11a of the printed circuit board 11, and transmits the detection result to the control device 50 as a signal. Further, the operation panel is provided with a switch for turning on and off the electrical inspection apparatus 10, operation keys for inputting various data, and the like.

この構成において、電気検査装置１０を用いてプリント基板１１の導通検査を行う場合には、まず、操作盤の操作キーを操作して、使用する検査用プローブ３６，４６に関するデータを入力する。そして、プリント基板１１を、設置装置２０に設置する。この場合、一対の把持部２４ａと一対の把持部２４ｂとの対向する部分の間隔がプリント基板１１の長さと同じ長さになるように固定装置２０ａ，２０ｂを移動させる。ついで、把持部２４ａ，２４ａの間隔および把持部２４ｂ，２４ｂの間隔がプリント基板１１の幅方向の長さと同じになるように把持機構２２ａ，２２ａと把持機構２２ｂ，２２ｂをそれぞれ移動させる。そして、各把持部２４ａ，２４ｂでプリント基板１１の対応する角部を挟むことにより、プリント基板１１を張った状態で設置する。   In this configuration, when conducting the continuity test of the printed circuit board 11 using the electrical test apparatus 10, first, the operation keys on the operation panel are operated to input data relating to the test probes 36 and 46 to be used. Then, the printed circuit board 11 is installed on the installation device 20. In this case, the fixing devices 20 a and 20 b are moved so that the distance between the opposing portions of the pair of gripping portions 24 a and the pair of gripping portions 24 b is the same as the length of the printed circuit board 11. Next, the gripping mechanisms 22a and 22a and the gripping mechanisms 22b and 22b are moved so that the distance between the gripping parts 24a and 24a and the distance between the gripping parts 24b and 24b are the same as the length in the width direction of the printed board 11. Then, the printed circuit board 11 is installed in a stretched state by sandwiching the corresponding corners of the printed circuit board 11 between the gripping portions 24a and 24b.

つぎに、移動装置１５、移動装置１６および移動部３１のモータ３２を駆動させることにより検出部３７をプリント基板１１における所定の接点１１ａの上方に移動させる。ついで、移動装置１８、移動装置１９および移動部４１のモータ４２を駆動させることにより検出部４７をプリント基板１１における所定の接点１１ａの下方に移動させる。そして、さらにモータ４２を駆動させて、検出部４７を上昇させて検査用プローブ４６を、プリント基板１１の接点１１ａに接触させる。ついで、モータ３２を駆動させることにより、検出部３７を下降させて検査用プローブ３６を、プリント基板１１の接点１１ａに接触させる。   Next, the detection unit 37 is moved above a predetermined contact 11 a on the printed circuit board 11 by driving the motor 32 of the movement device 15, the movement device 16, and the movement unit 31. Next, by driving the motor 42 of the moving device 18, the moving device 19, and the moving unit 41, the detection unit 47 is moved below the predetermined contact 11 a on the printed board 11. Then, the motor 42 is further driven to raise the detection unit 47 and bring the inspection probe 46 into contact with the contact 11 a of the printed circuit board 11. Next, by driving the motor 32, the detection unit 37 is lowered to bring the inspection probe 36 into contact with the contact 11 a of the printed board 11.

これによって、モータ３２には、プリント基板１１に対する検査用プローブ３６の押圧力の反力が検出部３７を介して伝わる。この反力を反力検出センサ３８が検出し、その検出信号を制御装置５０のＲＡＭ５３に送る。ＣＰＵ５１はＲＯＭ５２に記憶されたプログラムにしたがってデータ処理を行い、押圧力算出用データ５３ａから適正な押圧力を算出するとともに、その算出値と反力検出センサ３８の検出値との比較を行う。そして、モータ３２にその押圧力を出力させるための電流値を算出する。そして、ＣＰＵ５１は算出した電流値によりモータ３２を駆動させて検査用プローブ３６によるプリント基板１１の押圧力が算出値になるようにする。   As a result, the reaction force of the pressing force of the inspection probe 36 against the printed circuit board 11 is transmitted to the motor 32 via the detection unit 37. This reaction force is detected by the reaction force detection sensor 38, and the detection signal is sent to the RAM 53 of the control device 50. The CPU 51 performs data processing according to the program stored in the ROM 52, calculates an appropriate pressing force from the pressing force calculation data 53a, and compares the calculated value with the detection value of the reaction force detection sensor 38. Then, a current value for causing the motor 32 to output the pressing force is calculated. Then, the CPU 51 drives the motor 32 with the calculated current value so that the pressing force of the printed circuit board 11 by the inspection probe 36 becomes the calculated value.

これによって、検査用プローブ３６は、適正な押圧力でプリント基板１１の接点１１ａに接触する。その状態で検査用プローブ３６に通電することにより導通検査を行う。導通検査が終了すると、前述した各装置を駆動させることにより、検出部４７を下降させるとともに検出部３７を上昇させて元の状態に戻す。そして、前述した操作を再度行うことにより、プリント基板１１における次の検査位置に、検出部３７を移動させてその部分の導通検査を行う。これを順次繰り返すことにより、プリント基板１１における全ての部分の検査が行われる。   As a result, the inspection probe 36 contacts the contact 11a of the printed circuit board 11 with an appropriate pressing force. In this state, continuity inspection is performed by energizing the inspection probe 36. When the continuity test is completed, the above-described devices are driven to lower the detection unit 47 and raise the detection unit 37 to return to the original state. Then, by performing the above-described operation again, the detection unit 37 is moved to the next inspection position on the printed circuit board 11, and the continuity inspection of that portion is performed. By repeating this in sequence, all parts of the printed circuit board 11 are inspected.

また、下部検出装置４０を用いて、プリント基板１１に対する検査用プローブ４６の押圧力が算出値になるようにしてプリント基板１１の導通検査を行う場合には、検出部３７を下降させて検査用プローブ３６を、プリント基板１１の接点１１ａに接触させた状態で、検出部４７を上昇させて検査用プローブ４６を、プリント基板１１の接点１１ａに接触させる。これによって、モータ４２には、プリント基板１１に対する検査用プローブ４６の押圧力の反力が検出部４７を介して伝わる。この反力を反力検出センサ４８が検出し、その検出信号をＲＡＭ５３に送る。 Further, when conducting the continuity inspection of the printed circuit board 11 using the lower detection device 40 so that the pressing force of the inspection probe 46 against the printed circuit board 11 becomes a calculated value, the detection unit 37 is lowered to perform the inspection. In a state where the probe 36 is in contact with the contact 11 a of the printed circuit board 11, the detection unit 47 is raised to bring the inspection probe 46 into contact with the contact 11 a of the printed circuit board 11. As a result, the reaction force of the pressing force of the inspection probe 46 against the printed circuit board 11 is transmitted to the motor 42 via the detection unit 47. This reaction force is detected by the reaction force detection sensor 48, and the detection signal is sent to the RAM 53.

検出信号が送られたＣＰＵ５１は、押圧力算出用データ５３ａから適正な押圧力を算出するとともに、その算出値と反力検出センサ４８の検出値との比較を行う。そして、モータ４２にその押圧力を出力させるための電流値を算出する。そして、ＣＰＵ５１は算出した電流値によりモータ４２を駆動させて検査用プローブ４６によるプリント基板１１の押圧力が算出値になるようにし、その状態で検査用プローブ４６に通電することにより導通検査を行う。   The CPU 51 to which the detection signal is sent calculates an appropriate pressing force from the pressing force calculation data 53 a and compares the calculated value with the detection value of the reaction force detection sensor 48. Then, a current value for causing the motor 42 to output the pressing force is calculated. Then, the CPU 51 drives the motor 42 with the calculated current value so that the pressing force of the printed circuit board 11 by the inspection probe 46 becomes the calculated value, and conducts the continuity test by energizing the inspection probe 46 in that state. .

また、大きさの異なる別のプリント基板の導通検査を行う場合には、検査済みのプリント基板１１の各角部を、把持部２４ａ，２４ｂから外して、プリント基板１１を電気検査装置１０から取り出し、つぎのプリント基板を設置装置２０に設置する。この場合、前述した操作を行うことにより、把持部２４ａ，２４ｂの位置をプリント基板の四隅に対応する間隔に位置決めする。そして、そのプリント基板の各角部を把持部２４ａ，２４ｂで挟んで固定することによりプリント基板の設置を行う。導通検査は、前述した操作にしたがって行われる。また、板状のプリント基板の導通検査を行う場合には、上部検出装置３０と下部検出装置４０とを同時に作動させながら導通検査を行うこともできる。   When conducting a continuity test of different printed circuit boards having different sizes, the corners of the inspected printed circuit board 11 are removed from the gripping parts 24a and 24b, and the printed circuit board 11 is taken out from the electrical inspection apparatus 10. Then, the next printed circuit board is installed in the installation apparatus 20. In this case, by performing the above-described operation, the positions of the grip portions 24a and 24b are positioned at intervals corresponding to the four corners of the printed circuit board. Then, the printed circuit board is installed by fixing each corner of the printed circuit board with the gripping parts 24a and 24b. The continuity test is performed according to the operation described above. Further, when conducting a continuity test on a plate-like printed circuit board, the continuity test can be performed while simultaneously operating the upper detection device 30 and the lower detection device 40.

このように、本発明に係る電気検査装置１０では、プリント基板１１から検査用プローブ３６，４６に掛かる反力を検出する反力検出センサ３８，４８が、検出部３７，４７でなく、制御装置５０の近傍に取り付けられている。そして、反力検出センサ３８，４８は、プリント基板１１に対する検査用プローブ３６，４６の押圧力を検出部３７，４７を介してモータ３２，４２に掛かる反力として検出するように構成されている。このため、検査用プローブ３６，４６を検出部３７，４７とともに取り替えても、反力検出センサ３８，４８は取り替えることなくそのまま使用できるようになる。   As described above, in the electrical inspection apparatus 10 according to the present invention, the reaction force detection sensors 38 and 48 for detecting the reaction force applied to the inspection probes 36 and 46 from the printed circuit board 11 are not the detection units 37 and 47 but the control device.

The reaction force detection sensors 38 and 48 are configured to detect the pressing force of the inspection probes 36 and 46 against the printed circuit board 11 as the reaction force applied to the motors 32 and 42 via the detection units 37 and 47. . Therefore, even if the inspection probes 36 and 46 are replaced together with the detection units 37 and 47, the reaction force detection sensors 38 and 48 can be used as they are without replacement.

また、検査用プローブ３６，４６によるプリント基板１１への押圧力を適正な値に制御できるため、検査用プローブ３６，４６とプリント基板１１の接点１１ａとの接触不良がなくなり精度のよい電気検査が行える。さらに、検査用プローブ３６，４６と接点１１ａとの接触が適正状態で行われるため、検査用プローブ３６，４６が破損することも防止される。また、反力検出センサ３８，４８が、モータ３２，４２に掛かる反力を検出するように構成されているため、制御装置５０の近傍だけでなく、移動部３１，４１等任意の部分に設けることもできる。これによって、反力検出センサ３８，４８の設置位置に自由度が増すようになる。   In addition, since the pressing force applied to the printed circuit board 11 by the inspection probes 36 and 46 can be controlled to an appropriate value, there is no contact failure between the inspection probes 36 and 46 and the contact 11a of the printed circuit board 11, and an accurate electrical inspection can be performed. Yes. Furthermore, since the inspection probes 36 and 46 and the contact point 11a are contacted in an appropriate state, the inspection probes 36 and 46 are prevented from being damaged. Further, since the reaction force detection sensors 38 and 48 are configured to detect the reaction force applied to the motors 32 and 42, the reaction force detection sensors 38 and 48 are provided not only in the vicinity of the control device 50 but also in any part such as the moving parts 31 and 41. You can also. This increases the degree of freedom in the installation positions of the reaction force detection sensors 38 and 48.

In this case, the reaction force detection sensors 38, 48 are the reaction force detection sensors 38, 48 or support members from the printed circuit board 11 via the detection units 37, 47 when the inspection probes 36, 46 press the printed circuit board 11. The reaction force applied to 35 and 45 is detected. Also by this, even if the inspection probes 36 and 46 are replaced, the reaction force detection sensors 38 and 48 can be used as they are without replacement.

また、本発明は、前述した実施形態に限定するものでなく、本発明の技術的範囲において適宜変更実施が可能である。例えば、前述した実施形態では、プリント基板１１の上方と下方にそれぞれ上部検出装置３０と下部検出装置４０を設けたが、この検出装置は、どちらか一方だけに設けてもよい。また、図６に示した項目についても、これに限るものでなく、適正な押圧力を求めることのできるデータであれば他の特性に基づく項目を用いることもできる。   Further, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the technical scope of the present invention.
