Description

【0001】
【発明の属する技術分野】
本発明は、両面実装基板の既実装面を下受けする下受け治具のピンの配列を決定する実装基板用下受けピンの配列装置ならびに配列方法に関するものである。
【0002】
【従来の技術】
電子部品が実装される基板には、基板の片面のみならず両面に電子部品が実装されるいわゆる両面実装基板がある。この両面実装基板の実装工程では、まず第1面への実装が行われた後、基板を反転して第2面への実装が行われる。この第2面への実装の際には、第1面すなわち電子部品が実装された既実装面が下向きとなるため、基板を実装位置に位置決めして保持する際には電子部品が障害となって既実装面を直接的に面支持することが出来ない。このため既実装面の電子部品実装部位以外の下受け可能部位を適宜選定し、この位置を下受けピンによって支持する方法が用いられる。この方法では、多数のピン孔が設けられたプレート部材より成る下受け治具上で前述の下受け可能部位に対応したピン孔の位置を選定し、これらのピン孔に下受けピンを装着することにより、各基板種類に対応した下受け治具が準備される。
【0003】
【発明が解決しようとする課題】
従来は下受けピンの装着作業において、作業者が実物基板を観察することによりピン位置を選定していた。しかしながら、単に目視によりいわゆる目見当によってピン位置を選定する方法は非常に効率が悪く、ピンと電子部品との干渉によって幾度もやり直す場合が多く、多大の手間と時間を要するものであった。このため、この下受けピンの配列を効率よく行うことが求められ、例えば基板上での電子部品の位置を表す実装データに基づいて配列を自動的に決定させる試みも検討されたが、このような方法は煩雑な手間を要するため実用的な方法とは云えないものであり、簡便で実用的な下受けピンの配列方法が求められていた。
【0004】
そこで本発明は、簡便で実用的な方法で下受けピン配列が行える実装基板用下受けピンの配列装置ならびに配列方法を提供することを目的とする。
【0006】
【課題を解決するための手段】
請求項1記載の実装基板用下受けピンの配列装置は、両面実装基板への電子部品の実装において、既実装面を下受けする下受け治具における下受けピンの配列を決定する実装基板用下受けピンの配列装置であって、既実装基板の既実装面の下受け可能部位を指標する第1の位置指標手段と、前記既実装面を下受けする下受けピンが装着される下受け治具上の位置を指標する第2の位置指標手段と、第1の位置指標手段による指標位置と第2の位置指標手段による指標位置とを対応させる位置対応手段とを備え、前記位置指標手段はレーザ光のスポットを照射するレーザポインタであり、前記位置対応手段は、前記既実装基板と下受け治具とを線対称に配置する配置手段と、この対称線上を移動する移動手段と、この移動手段に設けられたピニオンと、このピニオンに噛み合ってそれぞれ前記既実装基板上および下受け治具上に展張された2本のラック部材とを含み、前記第1の位置指標手段及び前記第2の位置指標手段は、前記ピニオンの中心点に対して対称位置に装着されている
【0008】
請求項記載の実装基板用下受けピン配列方法は、請求項1記載の実装基板用下受けピンの配列装置を用いる実装基板用下受けピンの配列方法であって、既実装基板の既実装面の下受け可能部位を第1の位置指標手段によって指標し、この指標位置を下受け治具上に設けられた第2の位置指標手段の指標位置に位置対応手段によって対応させ、この第2の位置指標手段による指標位置に下受けピンを装着するようにした。
【0009】
請求項記載の実装基板用下受けピン配列方法は、請求項記載の下受けピン配列方法であって、前記位置指標手段はレーザ光のスポットを照射するレーザポインタであり、前記位置対応手段は、前記実装基板と下受け治具とを線対称に配置する配置手段と、この対称線上を移動する移動手段と、この移動手段上に設けられたピニオンと、このピニオンに噛み合ってそれぞれ前記既実装基板上および下受け治具上に展張された2本のラック部材とを含む。
【0010】
本発明によれば、片面に電子部品が実装された既実装基板の下受け面の下受け可能部位に対応する下受け治具上の位置を位置指標手段によって指標させることにより、簡便な方法で効率よく下受けピンの配列を行うことができる。
【0011】
【発明の実施の形態】
次に本発明の実施の形態を図面を参照して説明する。図1は本発明の一実施の形態の電子部品実装装置の平面図、図2は同図3は同電子部品実装装置の電子部品実装位置の断面図、実装基板用下受けピンの配列装置の平面図、図4は同実装基板用下受けピンの配列装置の側面図、図5(a),(b),(c)は同実装基板用下受けピンの配列方法の工程説明図である。
【0012】
まず図1を参照して電子部品実装装置の構造について説明する。図1において、基台1の中央部には搬送路2が配設されている。搬送路2は基板3を搬送し、電子部品実装位置にて基板3を位置決めする。搬送路2の側方には電子部品の供給部4が設けられている。供給部4には多数基のテープフィーダ5が並設されている。テープフィーダ5は電子部品をピックアップ位置まで供給する。
【0013】
基台1の上面の両側端にはY軸テーブル8Aおよびスライドガイド8Bが並列に配設されており、Y軸テーブル8Aおよびスライドガイド8BにはX軸テーブル7が架設されている。X軸テーブル7には移載ヘッド6が装着されている。X軸テーブル7およびY軸テdーブル8Aを駆動することにより、移載ヘッド6は水平方向に移動し、供給部4のテープフィーダ5から電子部品をピックアップし基板3上に実装する。
【0014】
次に図2を参照して搬送路2の中央部に設けられている電子部品実装位置の構造について説明する。図2において、搬送路2の搬送レール2aはブラケット30によってベース部材31上に立設されている。ベース部材31は、両側端に設けられた送りねじ32およびナット33より成る上下動機構をモータ34で駆動することにより、スライドガイド35にガイドされて昇降する。
【0015】
ベース部材31には下受け治具13が配設されており、下受け治具13は送りねじ36、ナット37、モータ38より成る昇降機構によりガイドシャフト39のガイドされて昇降する。下受け治具13には下受けピン18が多数垂直に装着されており、下受けピン18は下受け治具13を上昇させた状態で搬送レール2a上で位置決めされた両面実装基板の下面、すなわち既に前工程において電子部品Pが実装された既実装面を支持する。これらの下受けピン18は、基板品種毎に既実装面の電子部品との位置的な干渉を生じないような位置を選定して装着される。
【0016】
再び図1において、電子部品実装位置の側方には実装基板用下受けピンの配列装置10が配設されている。配列装置10は両面実装基板を実装対象とする場合において、対象基板の品種切り替えが行われた場合に、下受け治具13の下受けピン18の配列を基板品種に応じて変更する際に用いられるものである。配列装置10は、上記位置に固定配置されるか、または使用の都度上記配設位置に装着され不使用時には取り外される。
【0017】
以下、図3、図4を参照して配列装置10について説明する。図3、図4に示すように、下受け治具13上には片面に電子部品が実装された既実装基板3’を支持する下受けピン18が装着されるピン孔13aが多数設けられている。下受けピンの配列作業においては、装着された下受けピン18の位置が既実装の電子部品位置と干渉することなく下受けピン18が基板面を直接支持するようなピン孔13aの選定が行われる。
【0018】
下受け治具13に並行した位置には、移動手段としての移動テーブル15が配設され、この移動テーブル15について下受け治具13と対称の位置には、基板載置部11が配設されている。基板載置部11上には、既実装基板の実物がサンプル基板として既実装面を上向きにして載置される。このとき、電子部品Pが実装された既実装基板3’は下受け治具13に対して移動テーブル15の中心線について線対称となるように配置される。すなわち、基板載置部11は既実装基板3’を下受け治具13に対して線対称に配置する配置手段となっている。
【0019】
下受け治具13と基板載置部11の間の移動テーブル15には、ピン位置配列ユニット14が設けられている。ピン位置配列ユニット14は、移動テーブル15から両外側方向にスライド自在に展張された2つのアーム17A,17Bを備えている。図2に示すように、移動テーブル15の可動部に相対向して立設された2つのブラケット20A,20Bの側面にはスライダ21A,21Bが固着され、スライダ21A,21Bと摺動自在に嵌合したスライドレール22A,22Bは、プレート23A,23Bに固着されている。プレート23A,3Bの反対面にはラック部材24A,24Bが配設され、ラック部材24A,24Bはブラケット20A,20Bに回転自在に支持されたピニオン25を両側から挟み込んで噛み合っている。
【0020】
ピニオン25は移動テーブル15の中心線CL上に位置しており、一方側のアーム17Aを矢印方向に移動させることにより、他方側のアーム17Bは反対方向に中心線CLについて対称方向への移動を行う。プレート23A,23Bの先端部の側面にはぞれレーザポインタ26A,26Bがピニオン25の中心点に対して対称位置に装着されている。レーザポインタ26A,26Bは下方にレーザ光のスポットを照射し、照射された点を指標する。
【0021】
アーム17A,17Bを移動させながらレーザポインタ26A,26Bを照射することにより、既実装基板3’上の任意の点の、中心線CLに関する下受け治具13上の対称点を求めることができる。すなわちレーザポインタ26によって既実装基板3’上の特定の点を指標すれば、下受け治具13上におけるレーザポインタ26は、この点の中心線CLに関する対称点を指標している。
【0022】
次に図5を参照して下受けピン配列方法について説明する。図5(a)に示すように、基板載置部11上にサンプル基板としての既実装基板3’を載置する。次いでレーザポインタ26Aを照射してアーム17Aを手動で水平方向に移動させることにより、レーザスポットによって電子部品P以外の位置、すなわち下受け可能部位を指標させる。すなわちレーザポインタ26Aは第1の位置指標手段となっている。
【0023】
これにより、下受け治具13上に位置するレーザポインタ26Bは前記下受け可能部位に対応する位置をレーザスポットにより指標する。すなわちこのレーザポインタ26Bは第2の位置指標手段となっている。前述のように、2つのレーザポインタ26A,26Bは、ラック部材24A,24Bとピニオン25を介して連結され常に中心線CLに関して互いに線対称な位置にある。したがって、基板載置部11、移動テーブル15、ラック部材24およびピニオン25は、2つのレーザポインタ26A,26Bによる指標位置を相互に対応させる位置対応手段となっている。
【0024】
このようにして、既実装基板3’上で下受け部位を決定し、これに対応する下受け治具13上のピン孔13aを特定する。この操作を行うとき、逆に下受け治具13上のピン孔13aをレーザポインタ26Bで指標し、このピン孔13aに対応する既実装基板3’上の点に電子部品が存在するか否かをチェックするようにしてもよい。
【0025】
このようにして必要な下受け位置が求められたならば、図5(b)に示すように当該ピン孔13aに下受けピン18を装着する。次いで図5(c)に示すように既実装基板3’を下受け治具13上に既実装面を下向きにして載置する。このとき、下受けピン18の配列は既実装基板3’の電子部品Pが存在しない部位に対応して正しく決定されているため、下受けピン18と電子部品Pの位置の干渉を生じることがなく、従来たびたび行っていた位置修正のためのやり直し作業を必要としない。したがって、従来の試行によるピン位置決定方法と比較して、ピン配列作業の効率を格段に向上させることができる。
【0026】
なお、本実施の形態では位置対応手段としてラック部材とピニオンの組み合わせを用いているが、これ以外にも平面座標を数値的に検出して反対側の位置指標手段にならい動作を行わせる方法などを用いてもよい。また、本実施の形態では搬送路2の側方に配列装置10を配置して電子部品実装位置において直接下受けピンの位置を選定する作業を行うようにしているが、電子部品実装装置の外部に配列装置10を配置し、オフライン作業で下受けピンの配列を行うようにしてもよい。また、本実施の形態では、レーザポインタによって下受け可能位置を指標しているが、下受けピンに相当する部材を昇降させて基板や電子部品に接触させることにより、部品存在の有無をチェックして指標するものであってもよい。
【0027】
さらに、本実施の形態では電子部品実装用装置として、電子部品を搭載する電子部品実装装置の例を示しているが、これに限定されず、クリーム半田印刷装置やボンド塗布装置など片面に電子部品を実装した後に他面に再度実装作業を行うために用いられるものであれば本発明を適用することができる。
【0028】
【発明の効果】
本発明によれば、片面に電子部品が実装された既実装基板の既実装面の下受け可能部位に対応する下受け治具上の位置を位置指標手段によって指標させるようにしたので、簡便な方法で効率よく実装基板用下受けピンの配列を行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to apparatus for arranging and arrangement method of the pin receiving lower for mounting a substrate to determine the sequence of pins of the lower receiving jig receiving under the already mounting surfaces of the surface mount board.
[0002]
[Prior art]
As a substrate on which electronic components are mounted, there is a so-called double-sided mounting substrate in which electronic components are mounted on both sides as well as one side of the substrate. In the mounting process of the double-sided mounting substrate, first, mounting on the first surface is performed, and then the substrate is reversed and mounting on the second surface is performed. When mounting on the second surface, the first surface, that is, the already mounted surface on which the electronic component is mounted faces downward, so that the electronic component becomes an obstacle when the substrate is positioned and held at the mounting position. Therefore, it is not possible to directly support the already mounted surface. For this reason, a method is used in which an under-mountable portion other than the electronic component mounting portion on the already mounted surface is appropriately selected and this position is supported by the under-pin. In this method, the positions of the pin holes corresponding to the above-described portions that can be received are selected on a receiving jig made of a plate member provided with a large number of pin holes, and the receiving pins are attached to these pin holes. Thus, a receiving jig corresponding to each substrate type is prepared.
[0003]
[Problems to be solved by the invention]
Conventionally, in the mounting work of the receiving pin, the operator selects the pin position by observing the actual substrate. However, the method of selecting the pin position by visual inspection so-called register is very inefficient and often re-executed many times due to the interference between the pin and the electronic component, which requires a lot of labor and time. For this reason, it is required to efficiently arrange the receiving pins. For example, an attempt to automatically determine the arrangement based on mounting data representing the position of the electronic component on the board has been studied. Since this method requires complicated labor, it cannot be said to be a practical method, and there has been a demand for a simple and practical arrangement method of receiving pins.
[0004]
Accordingly, the present invention aims at providing a convenient and practical apparatus for arranging the pin receiving lower for the implementation substrate that can lower receiving pins sequences in a manner and arrangement method.
[0006]

[0008]
The mounting method of the mounting pins for the mounting board according to claim 2 is an arraying method of the mounting pins for the mounting substrate using the mounting device for mounting the mounting pins of the mounting substrate according to claim 1. The position where the mounting surface can be received is indexed by the first position index means, and the index position is made to correspond to the index position of the second position index means provided on the support jig by the position corresponding means.

It is possible to arrange the receiving pins efficiently.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an electronic component mounting apparatus according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the electronic component mounting position of the electronic component mounting apparatus, and FIG. FIG. 4 is a side view of the mounting substrate lower pin arranging device, and FIGS. 5A, 5B, and 5C are process explanatory views of the mounting substrate lower pin arranging method. .
[0012]
First, the structure of the electronic component mounting apparatus will be described with reference to FIG. In FIG. 1, a transport path 2 is disposed at the center of a base 1. The conveyance path 2 conveys the board 3 and positions the board 3 at the electronic component mounting position. An electronic component supply unit 4 is provided on the side of the conveyance path 2. A large number of tape feeders 5 are arranged in the supply unit 4 in parallel. The tape feeder 5 supplies electronic components to the pickup position.
[0013]
A Y-axis table 8A and a slide guide 8B are arranged in parallel on both side ends of the upper surface of the base 1, and an X-axis table 7 is installed on the Y-axis table 8A and the slide guide 8B. A transfer head 6 is mounted on the X-axis table 7. By driving the X-axis table 7 and the Y-axis table 8A, the transfer head 6 moves in the horizontal direction, picks up an electronic component from the tape feeder 5 of the supply unit 4, and mounts it on the substrate 3.
[0014]
Next, with reference to FIG. 2, the structure of the electronic component mounting position provided in the central portion of the conveyance path 2 will be described. In FIG. 2, the transport rail 2 a of the transport path 2 is erected on a base member 31 by a bracket 30. The base member 31 is moved up and down by being guided by a slide guide 35 by driving a vertical movement mechanism composed of a feed screw 32 and a nut 33 provided on both side ends by a motor 34.
[0015]
A lower receiving jig 13 is disposed on the base member 31, and the lower receiving jig 13 is moved up and down by a guide shaft 39 guided by an elevating mechanism including a feed screw 36, a nut 37, and a motor 38. A number of lower receiving pins 18 are vertically mounted on the lower receiving jig 13, and the lower receiving pins 18 are positioned on the transport rail 2 a with the lower receiving jig 13 being lifted, That is, the already mounted surface on which the electronic component P is already mounted in the previous process is supported. These receiving pins 18 are mounted by selecting positions that do not cause positional interference with electronic components on the already mounted surface for each board type.
[0016]
Referring again to FIG. 1, a mounting board receiving pin arraying device 10 is disposed on the side of the electronic component mounting position. The array device 10 is used to change the array of the receiving pins 18 of the receiving jig 13 according to the substrate type when the type of the target substrate is switched when the double-sided mounting substrate is to be mounted. It is what The arrangement device 10 is fixedly arranged at the above position, or is mounted at the above arrangement position every time it is used, and is removed when not in use.
[0017]
Hereinafter, the arrangement device 10 will be described with reference to FIGS. 3 and 4. As shown in FIGS. 3 and 4, the lower receiving jig 13 is provided with a number of pin holes 13 a for receiving lower receiving pins 18 that support an already mounted substrate 3 ′ on which electronic components are mounted on one side. Yes. In the work of arranging the receiving pins, the pin hole 13a is selected such that the position of the mounted receiving pins 18 does not interfere with the position of the already mounted electronic component so that the receiving pins 18 directly support the board surface. Is called.
[0018]
A moving table 15 as a moving means is disposed at a position parallel to the lower receiving jig 13, and a substrate placing portion 11 is disposed at a position symmetrical to the lower receiving jig 13 with respect to the moving table 15. ing. On the board | substrate mounting part 11, the actual thing of an already mounted board | substrate is mounted as a sample board | substrate with the already mounted surface facing up. At this time, the already mounted substrate 3 ′ on which the electronic component P is mounted is arranged so as to be line symmetric with respect to the center line of the moving table 15 with respect to the receiving jig 13. That is, the substrate mounting portion 11 is an arrangement means for arranging the already mounted substrate 3 ′ in line symmetry with the receiving jig 13.
[0019]
A pin position array unit 14 is provided on the moving table 15 between the lower receiving jig 13 and the substrate platform 11. The pin position array unit 14 includes two arms 17A and 17B that are slidably extended from the moving table 15 in both outward directions. As shown in FIG. 2, sliders 21A and 21B are fixed to the side surfaces of two brackets 20A and 20B that are erected opposite to the movable part of the moving table 15, and are slidably fitted to the sliders 21A and 21B. The combined slide rails 22A and 22B are fixed to the plates 23A and 23B. Rack members 24A and 24B are disposed on the opposite surfaces of the plates 23A and 3B, and the rack members 24A and 24B mesh with the pinions 25 supported rotatably on the brackets 20A and 20B from both sides.
[0020]
The pinion 25 is located on the center line CL of the moving table 15. By moving the arm 17A on one side in the direction of the arrow, the arm 17B on the other side moves in the opposite direction to the direction of symmetry with respect to the center line CL. Do. Laser pointers 26 </ b> A and 26 </ b> B are mounted on the side surfaces of the front end portions of the plates 23 </ b> A and 23 </ b> B at symmetrical positions with respect to the center point of the pinion 25. The laser pointers 26A and 26B irradiate a spot of laser light downward, and indicate the irradiated point.
[0021]
By irradiating the laser pointers 26A and 26B while moving the arms 17A and 17B, it is possible to obtain a symmetric point on the receiving jig 13 with respect to the center line CL at any point on the mounted substrate 3 ′. That is, if a specific point on the already mounted substrate 3 ′ is indicated by the laser pointer 26, the laser pointer 26 on the receiving jig 13 indicates a symmetric point with respect to the center line CL of this point.
[0022]
Next, the receiving pin arrangement method will be described with reference to FIG. As shown in FIG. 5A, an already mounted substrate 3 ′ as a sample substrate is placed on the substrate placing portion 11. Next, by irradiating the laser pointer 26A and manually moving the arm 17A in the horizontal direction, the laser spot causes a position other than the electronic component P, that is, a placeable part to be indicated. That is, the laser pointer 26A is a first position indicator.
[0023]
Thereby, the laser pointer 26B located on the lower receiving jig 13 indicates the position corresponding to the lower receiving portion by the laser spot. That is, the laser pointer 26B serves as a second position indicator. As described above, the two laser pointers 26A and 26B are connected to the rack members 24A and 24B via the pinion 25 and are always in positions symmetrical with respect to the center line CL. Therefore, the substrate platform 11, the moving table 15, the rack member 24, and the pinion 25 serve as position correspondence means that associates the index positions of the two laser pointers 26A and 26B with each other.
[0024]
In this manner, the receiving part is determined on the already mounted substrate 3 ′, and the pin hole 13a on the receiving jig 13 corresponding to this is specified. Conversely, when this operation is performed, the pin hole 13a on the receiving jig 13 is indexed by the laser pointer 26B, and whether or not an electronic component is present at a point on the already mounted substrate 3 ′ corresponding to the pin hole 13a. You may make it check.
[0025]
When the necessary receiving position is obtained in this way, the receiving pin 18 is attached to the pin hole 13a as shown in FIG. 5 (b). Next, as shown in FIG. 5C, the already mounted substrate 3 ′ is placed on the receiving jig 13 with the already mounted surface facing downward. At this time, since the arrangement of the receiving pins 18 is correctly determined corresponding to the portion of the mounted substrate 3 ′ where the electronic component P does not exist, interference between the positions of the receiving pins 18 and the electronic components P may occur. In addition, there is no need for rework for position correction, which has been frequently performed in the past. Therefore, the efficiency of the pin arrangement work can be significantly improved as compared with the conventional pin position determination method by trial.
[0026]
In this embodiment, a combination of a rack member and a pinion is used as the position correspondence means. However, in addition to this, a method of numerically detecting the plane coordinates and performing an operation following the position index means on the opposite side, etc. May be used. In the present embodiment, the arrangement device 10 is arranged on the side of the conveyance path 2 so that the position of the receiving pin is directly selected at the electronic component mounting position. It is also possible to arrange the arrangement device 10 and arrange the receiving pins in an off-line operation. Also, in this embodiment, the position where the lower plate can be received is indicated by the laser pointer. However, the presence or absence of the component is checked by moving the member corresponding to the lower support pin up and down to contact the substrate or the electronic component. May be used as an index.
[0027]
Furthermore, in this embodiment, an example of an electronic component mounting apparatus for mounting an electronic component is shown as the electronic component mounting apparatus, but the present invention is not limited to this, and an electronic component on one side such as a cream solder printing apparatus or a bond coating apparatus is shown. The present invention can be applied as long as it is used for performing mounting work on the other surface again after mounting.

【The invention's effect】
According to the present invention, the position indicator means indicates the position on the receiving jig corresponding to the placeable portion of the already mounted surface of the already mounted substrate on which the electronic component is mounted on one side. By this method, the mounting pins for the mounting board can be arranged efficiently.
