Description

本発明は、複数の下受けピンによって下面を支持された基板に電子部品を実装する電子部品実装装置および電子部品実装装置において下受けピンを下受けベース部に配置する下受けピンの配置方法ならびに配置されて使用された後の下受けピンを所定位置に返戻する下受けピンの返戻方法に関するものである。   The present invention relates to an electronic component mounting apparatus that mounts an electronic component on a substrate whose lower surface is supported by a plurality of lower receiving pins, an arrangement method of the lower receiving pins in the electronic component mounting apparatus, and an arrangement method of the lower receiving pins in the lower receiving base portion. The present invention relates to a return method of a receiving pin that returns the receiving pin after being placed and used to a predetermined position.

基板に電子部品を実装する部品実装工程においては、基板は下面側を下受け部によって支持された状態で位置決め保持される。この基板の下受け方式として、複数の下受けピンを基板の下面に当接させて支持する下受けピン方式が広く用いられる。この下受けピン方式におけるピンの配置方法として、従来よりバックアップベース(下受けベース)に格子状に形成されたピン装着孔に、バックアップピン(下受けピン)を嵌脱自在に立設する方法が知られている(例えば特許文献1,2参照)。これらの特許文献例に示す先行技術においては、バックアップベースのうち基板が載置されない領域を,基板を支持しないバックアップピンを収容するストックエリアとして用いるようにしている。そして特許文献1においては、ストックエリアからバックアップピンを移載する移載位置の遠近を考慮して移載順序を設定することによって、移載動作時におけるバックアップピン相互の干渉を防止するようにしている。   In the component mounting process for mounting the electronic component on the substrate, the substrate is positioned and held with the lower surface side supported by the lower receiving portion. As the base plate method for this substrate, a base pin method for supporting a plurality of base pins in contact with the lower surface of the substrate is widely used. As a method for arranging pins in the lower receiving pin method, there is a method in which a backup pin (lower receiving pin) is erected in a pin mounting hole formed in a lattice shape on the backup base (lower receiving base). Known (for example, see Patent Documents 1 and 2). In the prior art shown in these patent document examples, an area of the backup base where the substrate is not placed is used as a stock area for accommodating backup pins that do not support the substrate. In Patent Document 1, by setting the transfer order in consideration of the distance of the transfer position for transferring the backup pin from the stock area, the interference between the backup pins during the transfer operation is prevented. Yes.

近年電子機器の小型化の進展に伴う実装密度の高度化により、実装基板における下受けピンの配置をより精細に設定する必要が生じている。しかしながら上述の特許文献例に示す先行技術を含め、従来技術においてはピン装着孔が格子状に配列された下受けベースを用いることから、下受けベースに配置された状態の下受けピンの相互間隔には制約があり、高精細度のピン配列は困難であった。このような課題を克服するため、ピン装着孔が格子状に配列された下受けベース型に替えて、マグネット固定などによって自立可能な下受けピンを下受けベースの任意位置に配置する方式が用いられるようになっている。   In recent years, with the advancement of mounting density with the progress of miniaturization of electronic devices, it is necessary to set the placement of the receiving pins on the mounting substrate more finely. However, since the prior art including the prior art shown in the above-mentioned patent document examples uses a lower base in which pin mounting holes are arranged in a lattice pattern, the spacing between the lower base pins arranged in the lower base is not limited. Has a limitation, and pin arrangement with high definition is difficult. In order to overcome these problems, instead of using a base type with pin mounting holes arranged in a grid, a method of placing a base pin that can stand on its own by fixing the magnet at any position on the base is used. It is supposed to be.

ところが、このような下受けピンを下受けベースの任意位置に配置する方式においては、下受けピン配置のための移動作業や使用後に機種切替のために下受けピンを下受けベースから返戻するための移動作業において、下受けピン相互の干渉が生じやすくなっている。すなわち、格子状配列を基本とする従来技術においては、下受けピン相互の間隔が確保されているため干渉防止が容易であったが、任意位置に配置する方式では、ピン径寸法を最小間隔としてピン配置が設定されるため、下受けピンの移動経路や順序の設定が不適切である場合には、移動時のピン相互の干渉が発生するおそれがある。   However, in such a system in which the receiving pin is arranged at an arbitrary position on the receiving base, the receiving pin is returned from the receiving base for moving work for placing the receiving pin or switching the model after use. In the moving operation, the interference between the receiving pins is likely to occur. That is, in the prior art based on the lattice arrangement, it is easy to prevent interference because the interval between the receiving pins is secured, but in the method of arranging at an arbitrary position, the pin diameter dimension is set as the minimum interval. Since the pin arrangement is set, if the movement path and order of the receiving pins are inappropriate, there is a possibility that interference between the pins at the time of movement occurs.

このようなピン相互の干渉は、ピン移動時の昇降ストロークをピン高さ以上に設定することにより防止することが可能であるが、この場合には移載ヘッドのストロークを過大に設定することによる設備コスト増大とともに、昇降ストロークの増大に伴って基板種の切替の都度必要とされるピン配置、ピン返戻に要する作業時間の遅延によるタクトロスが生じて効率が悪く、生産性の低下が避けられない。このように、下受けピンを下受けベースの任意位置に配置する方式の電子部品実装装置においては、下受けピンの配置作業や返戻作業の効率化が困難であるという課題があった。   Such interference between pins can be prevented by setting the lift stroke during pin movement to be higher than the pin height. In this case, however, the transfer head stroke is set excessively. Along with the increase in equipment cost, the pin placement required every time the board type is switched and the tact loss due to the delay in the work time required to return the pin occurs, resulting in poor efficiency and unavoidable reduction in productivity. . As described above, in the electronic component mounting apparatus of the type in which the lower receiving pins are arranged at arbitrary positions on the lower receiving base, there is a problem that it is difficult to efficiently perform the arrangement work of the lower receiving pins and the returning operation.

そこで本発明は、下受けピンの配置作業や返戻作業を効率化することができる電子部品実装装置および電子部品実装装置において下受けピンを下受けベース部に配置する下受けピンの配置方法ならびに配置された下受けピンを所定位置に返戻する下受けピンの返戻方法を提供することを目的とする。   Accordingly, the present invention provides an electronic component mounting apparatus capable of improving the efficiency of placing and returning work of the receiving pins, and an arrangement method and arrangement of the receiving pins in which the receiving pins are arranged on the receiving base portion in the electronic component mounting apparatus. It is an object of the present invention to provide a return method of a lower receiving pin for returning the lower receiving pin to a predetermined position.

次に本発明の実施の形態を図面を参照して説明する。まず図1,図2を参照して、電子部品実装装置1の全体構成を説明する。電子部品実装装置1は実装ヘッドに装着された吸着ノズルによって電子部品を保持して基板に実装する機能を有している。図1において、基台1aの中央部には、X方向(基板搬送方向)に基板搬送機構2が配設されている。基板搬送機構2は上流側から搬入された基板3を搬送し、以下に説明する部品実装機構による実装作業位置に位置決めする機能を備えるものであり、並行に配設された2条の搬送レール2aを有している。基板搬送機構2の中央部には、搬入された基板3を下受けするための基板下受け機構2cおよび基板下受け機構2cによって持ち上げられた基板3の相対向する2辺の側端部を上方から押さえてクランプする押さえ部材2bを備えている。   Next, embodiments of the present invention will be described with reference to the drawings. First, the overall configuration of the electronic component mounting apparatus 1 will be described with reference to FIGS. The electronic component mounting apparatus 1 has a function of holding an electronic component by a suction nozzle mounted on a mounting head and mounting the electronic component on a substrate. In FIG. 1, a substrate transport mechanism 2 is arranged in the X direction (substrate transport direction) at the center of the base 1a. The board transport mechanism 2 has a function of transporting the board 3 carried in from the upstream side and positioning it at a mounting work position by a component mounting mechanism described below, and includes two transport rails 2a arranged in parallel. have. In the central portion of the substrate transport mechanism 2, a substrate lower receiving mechanism 2c for receiving the loaded substrate 3 and side edges of two opposite sides of the substrate 3 lifted by the substrate lower receiving mechanism 2c A pressing member 2b is provided for pressing and clamping from above.

基板搬送機構2の両側には、実装対象の電子部品を供給する部品供給部4が配置されている。部品供給部4には複数のテープフィーダ5が並列に配置されており、テープフィーダ5はキャリアテープに保持された部品を以下に説明する部品実装機構による取出位置までピッチ送りする機能を有している。基台1a上面のX方向の1端部上にはY軸移動テーブル6が配設されており、Y軸移動テーブル6には2台のX軸移動テーブル7がY方向にスライド自在に結合されている。X軸移動テーブル7には、それぞれ実装ヘッド8がX方向にスライド自在に装着されている。   On both sides of the substrate transport mechanism 2, component supply units 4 that supply electronic components to be mounted are arranged. A plurality of tape feeders 5 are arranged in parallel in the component supply unit 4, and the tape feeder 5 has a function of pitch-feeding the components held on the carrier tape to a take-out position by a component mounting mechanism described below. Yes. A Y-axis moving table 6 is disposed on one end in the X direction on the upper surface of the base 1a, and two X-axis moving tables 7 are slidably coupled to the Y-axis moving table 6 in the Y direction. ing.

By driving the head moving mechanism and moving the substrate recognition camera 10 above the substrate 3 held by the substrate transport mechanism 2, the substrate recognition camera 10 captures an image of the recognition mark formed on the substrate 3. A component recognition camera 11, a first nozzle storage unit 12, and a second nozzle storage unit 13 are disposed on the movement path of the mounting head 8 between the component supply unit 4 and the substrate transport mechanism 2. The component recognition camera 11 picks up an image of the component held by the mounting head 8 by performing a scanning operation in which the mounting head 8 taking out the component from the component supply unit 4 passes above the component recognition camera 11 in a predetermined direction. .

A suction nozzle 14B that is mounted on the nozzle holder 9a of the head 9 and holds the receiving pin 22 is housed and held. When the mounting head 8 accesses the first nozzle storage unit 12 and the second nozzle storage unit 13 and performs a nozzle replacement operation, the suction nozzle mounted on the unit holding head 9 is changed to a target and target component type. Can be exchanged accordingly.

図2を参照して、基板搬送機構2の構成および機能について説明する。図2に示すように、基板搬送機構2は並行に配設された2条の搬送レール2aより構成され、搬送レール2aの内側にはコンベア機構2dが搬送方向に沿って設けられている。基板3の両側端部をコンベア機構2dの上面に当接させた状態でコンベア機構2dを駆動することにより、基板3は基板搬送方向に搬送される。さらに、コンベア機構2dの内側には、押さえ部材2bにより基板の側端部を上方から押さえてクランプする際、基板3の側端部を下方から支持するクランプ部2eが下受けベース部21に当接することにより昇降自在に配設されている。基板搬送機構2の中央部には、部品実装機構による作業位置に対応して基板下受け機構2cが配設されている。   With reference to FIG. 2, the structure and function of the substrate transport mechanism 2 will be described. As shown in FIG. 2, the board | substrate conveyance mechanism 2 is comprised from the two conveyance rails 2a arrange | positioned in parallel, and the conveyor mechanism 2d is provided along the conveyance direction inside the conveyance rail 2a. By driving the conveyor mechanism 2d with both end portions of the substrate 3 in contact with the upper surface of the conveyor mechanism 2d, the substrate 3 is transported in the substrate transport direction. Further, inside the conveyor mechanism 2d, when clamping by pressing the side end of the substrate from above with the pressing member 2b, a clamp portion 2e that supports the side end of the substrate 3 from below is brought into contact with the lower receiving base portion 21. It is arranged so that it can be raised and lowered by contact. In the central portion of the board transport mechanism 2, a board lowering mechanism 2c is disposed corresponding to the work position by the component mounting mechanism.

基板下受け機構2cは、水平な板状の下受けベース部21を昇降機構20によって昇降(矢印a)させる構成となっており、下受けベース部21の上面には、基板3を下面側から支持する下受けピン22が立設されている。下受けピン22は下受けベース部21に当接する基部23から上方に棒状部24を延出させた構成となっており、棒状部24の上端部には、基板3の下面に当接して支持する当接部24aおよび下受けピン22を吸着ノズル14Bによって吸着保持するための鍔状部24bが設けられている。   The substrate receiving mechanism 2c is configured such that a horizontal plate-shaped lower receiving base portion 21 is moved up and down (arrow a) by an elevating mechanism 20, and the substrate 3 is placed on the upper surface of the lower receiving base portion 21 from the lower surface side. Supporting lower receiving pins 22 are erected. The lower receiving pin 22 has a structure in which a rod-shaped portion 24 extends upward from a base portion 23 that is in contact with the lower receiving base portion 21, and the upper end portion of the rod-shaped portion 24 is in contact with and supported by the lower surface of the substrate 3. A hook-like portion 24b for sucking and holding the contact portion 24a and the lower receiving pin 22 by the suction nozzle 14B is provided.

下受けベース部21は、アルミニウムなどの非磁性体より成る板部材21bの上面に鋼板などの磁性体21aを被覆した構成となっており、磁性体21a上の任意の位置には下受けピン22が下受け対象となる基板3の下受け位置に応じて配置される。この下受け配置状態において、基部23に内蔵されたマグネット部材(図示省略)によって、下受けピン22は磁性体21aとの間に作用する引磁力によって下受けベース部21の任意の位置に固定される。   The lower receiving base portion 21 has a structure in which a magnetic member 21a such as a steel plate is covered on the upper surface of a plate member 21b made of a nonmagnetic material such as aluminum, and a lower receiving pin 22 is provided at an arbitrary position on the magnetic member 21a. Are arranged according to the receiving position of the substrate 3 to be received. In this lower receiving arrangement state, the lower receiving pin 22 is fixed at an arbitrary position of the lower receiving base portion 21 by an attractive force acting between the magnetic member 21a and a magnet member (not shown) built in the base portion 23. The

この状態で、図2(b)に示すように、昇降機構20を駆動して下受けベース部21を上昇させる(矢印b)ことにより、棒状部24の上端部に設けられた当接部24aが基板3の下面に当接し、基板3は基板下受け機構2cの複数の下受けピン22によって下受け支持されるとともに、基板3の両端部が押さえ部材2bの下面に押し付けられて位置固定される。   In this state, as shown in FIG. 2 (b), the elevating mechanism 20 is driven to raise the lower receiving base portion 21 (arrow b), whereby the contact portion 24 a provided at the upper end portion of the rod-like portion 24. Contacts the lower surface of the substrate 3, and the substrate 3 is supported by the plurality of lower receiving pins 22 of the substrate lowering mechanism 2c, and both ends of the substrate 3 are pressed against the lower surface of the pressing member 2b to be fixed in position. The

図3(a)は、このようにして複数の下受けピン22によって下面を支持された基板3を対象とする部品実装動作を示している。すなわち、ノズルホルダ9aに装着された吸着ノズル14Aによって部品供給部4から電子部品Pを取り出した実装ヘッド8を基板3の上方に移動させ、単位保持ヘッド9が吸着ノズル14Aを昇降させる部品搭載動作を行うことにより、電子部品Pは基板3の実装点に実装される。   FIG. 3A shows a component mounting operation for the substrate 3 whose lower surface is supported by the plurality of support pins 22 in this way. That is, the component mounting operation in which the mounting head 8 that has taken out the electronic component P from the component supply unit 4 is moved above the substrate 3 by the suction nozzle 14A attached to the nozzle holder 9a, and the unit holding head 9 moves the suction nozzle 14A up and down. As a result, the electronic component P is mounted on the mounting point of the substrate 3.

このような部品搭載動作を異なる品種の基板3を対象として反復実行する過程においては、下受けベース部21における下受けピン22の配置変更が実行される。本実施の形態に示す電子部品実装装置1においては、このピン配置変更作業を実装ヘッド8による移載機能を利用して自動的に実行するようにしている。すなわち図3(b)に示すように、単位保持ヘッド9のノズルホルダ9aに下受けピン22の移動用に専用に設けられた吸着ノズル14Bを装着し、吸着ノズル14Bによって下受けピン22の棒状部24に設けられた鍔状部24bを吸着保持することにより、下受けピン22を下受けベース部21上の所望の位置に移動させる。   In the process of repeatedly performing such component mounting operation for different types of boards 3, the arrangement of the lower receiving pins 22 in the lower receiving base portion 21 is changed. In the electronic component mounting apparatus 1 shown in the present embodiment, this pin arrangement changing operation is automatically executed using the transfer function by the mounting head 8. That is, as shown in FIG. 3B, a suction nozzle 14B provided exclusively for moving the lower receiving pin 22 is attached to the nozzle holder 9a of the unit holding head 9, and the lower end of the lower receiving pin 22 is formed by the suction nozzle 14B. The lower receiving pin 22 is moved to a desired position on the lower receiving base portion 21 by sucking and holding the hook-shaped portion 24b provided on the portion 24.

次に図4を参照して、本実施の形態の電子部品実装装置1における基板下受け機構2cの下受けベース部21を対象とする下受けピン22の配置について説明する。図4(a)に示すように、基板3が搬入されていない状態では、基板下受け機構2cの下受けベース部21は上面が露呈され、実装ヘッド8による下受けピン22の移動が可能な状態となる。基板搬送機構2の近傍において実装ヘッド8の移動範囲内には、複数の下受けピン22を収納したピン収納部15が配設されており、実装ヘッド8をピン収納部15にアクセスさせることにより、単位保持ヘッド9によって下受けピン22を取り出し、下受けベース部21に移動させることができる。   Next, with reference to FIG. 4, the arrangement of the lower receiving pins 22 for the lower receiving base portion 21 of the substrate lowering mechanism 2c in the electronic component mounting apparatus 1 of the present embodiment will be described. As shown in FIG. 4A, when the substrate 3 is not carried in, the upper surface of the lower support base portion 21 of the substrate lower receiving mechanism 2c is exposed, and the lower receiving pins 22 can be moved by the mounting head 8. It becomes a state. In the vicinity of the substrate transport mechanism 2, a pin housing portion 15 that houses a plurality of receiving pins 22 is disposed within the movement range of the mounting head 8, and the mounting head 8 can be accessed by accessing the pin housing portion 15. The lower holding pin 22 can be taken out by the unit holding head 9 and moved to the lower receiving base portion 21.

図4(b)は、下受けベース部21におけるエリア分割を示している。下受けベース部21には、基板3を下受けするために複数の下受けピン22が、対象となる基板3の下受け位置に対応して任意の位置に配置される下受けエリアA1が設定されている。すなわち、基板下受け機構2cは、複数の下受けピン22が任意の位置に配置される下受けエリアA1が設定された下受けベース部21を有する構成となっている。   FIG. 4B shows area division in the lower base 21. The lower receiving base portion 21 is provided with a lower receiving area A1 in which a plurality of lower receiving pins 22 are arranged at arbitrary positions corresponding to the lower receiving positions of the target substrate 3 in order to receive the substrate 3. Has been. That is, the substrate support mechanism 2c is configured to have a support base portion 21 in which a support area A1 in which a plurality of support pins 22 are arranged at arbitrary positions is set.

さらに下受けエリアA1に隣接して、下受けエリアA1への配置前の下受けピン22が一時的に仮置きされる配置前仮置きエリアA2が、下受けベース部21においてX方向(第1方向)に沿って、且つX方向と直交するY方向(第2方向)の座標値が小さい側(図4において下側)の縁部に設定されている。配置前仮置きエリアA2には、ピン収納部15から実装ヘッド8によって取り出された下受けピン22が仮置きされる。そして配置前仮置きエリアA2に仮置きされた下受けピン22は、実装ヘッド8によって対象とする基板3の下受け位置に対応した配置位置に移動する。したがって実装ヘッド8および前述のヘッド移動機構は、配置前仮置きエリアA2に下受けピン22を仮置きするピン仮置き手段を構成するとともに、配置前仮置きエリアA2に仮置きされた下受けピン22を下受けエリアA1に配置するピン配置手段となっている。   Further, a temporary placement area A2 before placement in which the bottom placement pins 22 before placement in the placement area A1 are temporarily placed is adjacent to the placement area A1 in the X direction (first The coordinate value in the Y direction (second direction) perpendicular to the X direction is set to the edge on the smaller side (lower side in FIG. 4). In the pre-placement temporary placement area A2, the lower receiving pins 22 taken out by the mounting head 8 from the pin storage portion 15 are temporarily placed. Then, the support pins 22 temporarily placed in the pre-placement temporary placement area A <b> 2 are moved by the mounting head 8 to the placement position corresponding to the placement position of the target substrate 3. Therefore, the mounting head 8 and the head moving mechanism described above constitute a pin temporary placement means for temporarily placing the lower support pins 22 in the pre-placement temporary placement area A2, and the lower placement pins temporarily placed in the pre-placement temporary placement area A2. Pin arrangement means for arranging 22 in the receiving area A1.

本実施の形態において配置前仮置きエリアA2は、下受けエリアA1に配置されて基板3の下受けに使用された後に返戻される複数の下受けピン22が仮置きされる返戻後仮置きエリアA3を兼ねている。すなわち返戻後仮置きエリアA3は、下受けベース部21においてX方向(第1方向)に沿って且つX方向と直交するY方向(第2方向)の座標値が小さい側(図4において下側)の縁部に設定されている。なお、配置前仮置きエリアA2と返戻後仮置きエリアA3とを、それぞれ個別に独立した仮置きエリアとして設定してもよい。   In the present embodiment, the pre-placement temporary placement area A2 is a temporary placement area after return in which a plurality of support pins 22 that are returned after being placed in the support area A1 and used for the support of the substrate 3 are temporarily placed. Also serves as A3. That is, the post-return temporary placement area A3 has a lower coordinate value in the Y direction (second direction) along the X direction (first direction) and perpendicular to the X direction (lower side in FIG. 4). ) Is set at the edge. Note that the temporary placement area A2 before placement and the temporary placement area A3 after return may be set as independent temporary placement areas.

下受けエリアA1に配置されて使用された後の下受けピン22は、実装ヘッド8によって返戻後仮置きエリアA3内の対応する仮置き位置に移動する。したがって実装ヘッド8および前述のヘッド移動機構は、下受けエリアA1に配置された後に返戻される複数の下受けピン22が仮置きされる返戻後仮置きエリアA3に下受けピン22を仮置きする返戻後ピン仮置き手段を兼務している。   After being placed and used in the lower receiving area A1, the lower receiving pins 22 are moved by the mounting head 8 to a corresponding temporary placement position in the temporary placement area A3 after returning. Accordingly, the mounting head 8 and the above-described head moving mechanism temporarily place the lower receiving pins 22 in the temporary placement area A3 after returning, in which a plurality of lower receiving pins 22 that are returned after being placed in the lower receiving area A1 are temporarily placed. It also serves as a temporary pin placement means after returning.

次に、図5を参照して、下受けベース部21に設定された下受けエリアA1における下受けピン22の配置位置および配置前仮置きエリアA2(返戻後仮置きエリアA3)における下受けピン22の仮置き位置について説明する。図5(a)は、下受けエリアA1における下受けピン22の配置位置の一例を示しており、ここでは、6本の下受けピン22を配置するための配置位置AP1〜AP6が、対象とする基板3の下受け位置に応じて設定されている。各配置位置APの位置は、X方向(第1方向)の座標値x1〜x6、Y方向(第2方向)の座標値y1〜y6によって特定される。ここに示す例ではこれらの座標値の大小関係は、以下の通りとなっている。
x1<x2<x3(=x4)<x5(=x6)
y1>y5>y3>y2>y6(=y4)
Next, referring to FIG. 5, the arrangement position of the lower receiving pins 22 in the lower receiving area A1 set in the lower receiving base portion 21 and the lower receiving pins in the temporary placement area A2 before placement (temporary placement area A3 after returning). The 22 temporary placement positions will be described. FIG. 5A shows an example of the arrangement positions of the lower receiving pins 22 in the lower receiving area A1. Here, the arrangement positions AP1 to AP6 for arranging the six lower receiving pins 22 are targeted. It is set according to the receiving position of the substrate 3 to be performed. The position of each arrangement position AP is specified by coordinate values x1 to x6 in the X direction (first direction) and coordinate values y1 to y6 in the Y direction (second direction). In the example shown here, the magnitude relationship between these coordinate values is as follows.
x1 <x2 <x3 (= x4) <x5 (= x6)
y1>y5>y3>y2> y6 (= y4)

また図5(b)は、配置前仮置きエリアA2(返戻後仮置きエリアA3)における下受けピン22の仮置き位置の一例を示している。ここでは、配置前仮置きエリアA2(返戻後仮置きエリアA3)において、X方向(第1方向)の座標原点Oから近接した順に、配置前仮置きエリアA2に配置される下受けピン22の数に応じて、複数(ここでは6)の仮置き位置TP1〜TP6が列状に設定されている。   FIG. 5B shows an example of a temporary placement position of the receiving pin 22 in the temporary placement area A2 before placement (temporary placement area A3 after return). Here, in the pre-placement temporary placement area A2 (post-return temporary placement area A3), the receiving pins 22 placed in the pre-placement temporary placement area A2 in the order of approach from the coordinate origin O in the X direction (first direction). A plurality (six here) of temporary placement positions TP1 to TP6 are set in a line according to the number.

本実施の形態においては、配置前仮置きエリアA2への下受けピン22の配置のためのピン移動実行、配置されて使用された後の下受けピン22の下受けエリアA1からの返戻のためのピン移動実行に先立って、仮置き位置の割り当ておよび移動順序の設定が実行される。仮置き位置の割り当ては、配置位置AP1〜AP6に配置される下受けピン22と、これらの下受けピン22が仮置きされる仮置き位置TP1〜TP6との対応関係を定めるものであり、移動順序はこれらの下受けピン22を移動させる順序を定めるものである。この仮置き位置割り当ておよび移動順序の設定は、ピン移動実行時に下受けエリアA1に配置された下受けピン22と移動中の下受けピン22との干渉の発生を予め防止することを目的とするものである。   In the present embodiment, for the purpose of executing pin movement for placement of the backing pin 22 to the temporary placement area A2 before placement, and for returning from the backing area A1 of the backing pin 22 after placement and use. Prior to the execution of the pin movement, allocation of the temporary placement position and setting of the movement order are executed. The allocation of the temporary placement positions defines the correspondence between the lower receiving pins 22 arranged at the arrangement positions AP1 to AP6 and the temporary placement positions TP1 to TP6 where these lower receiving pins 22 are temporarily placed. The order determines the order in which the receiving pins 22 are moved. The purpose of this temporary placement position assignment and movement order setting is to prevent in advance the occurrence of interference between the lower receiving pins 22 arranged in the lower receiving area A1 and the moving lower receiving pins 22 when the pins are moved. Is.

次に、図6を参照して、制御系の構成を説明する。制御部30は、記憶部31に記憶された各種のプログラムやデータに基づいて電子部品実装装置1の各部を制御することにより、基板3を対象とする電子部品実装作業を実行する。制御部30は、内部制御処理機能として、実装動作処理部30a、配置前仮置き位置割当て処理部30b、返戻後仮置き位置割当て処理部30c、配置実行処理部30d、返戻実行処理部30eを備えている。   Next, the configuration of the control system will be described with reference to FIG. The control unit 30 executes an electronic component mounting operation for the board 3 by controlling each unit of the electronic component mounting apparatus 1 based on various programs and data stored in the storage unit 31. The control unit 30 includes, as internal control processing functions, a mounting operation processing unit 30a, a pre-placement temporary placement position assignment processing unit 30b, a post-return temporary placement position assignment processing unit 30c, a placement execution processing unit 30d, and a return execution processing unit 30e. ing.

記憶部31には、各基板3毎の実装データのほか、ピン配置データ32、仮置き位置データ33、配置前仮置き位置割当てデータ34、返戻後仮置き位置割当てデータ35が記憶される。ピン配置データ32は、図5(a)に示す下受けエリアA1における下受けピン22の配置位置APについてのデータである。仮置き位置データ33は、図5(b)に示す配置前仮置きエリアA2(返戻後仮置きエリアA3)における下受けピン22の仮置き位置TPについてのデータである。   In addition to the mounting data for each board 3, the storage unit 31 stores pin arrangement data 32, temporary placement position data 33, pre-placement temporary placement position assignment data 34, and post-return temporary placement position assignment data 35. The pin arrangement data 32 is data regarding the arrangement position AP of the receiving pin 22 in the receiving area A1 shown in FIG. The temporary placement position data 33 is data regarding the temporary placement position TP of the lower receiving pin 22 in the pre-placement temporary placement area A2 (post-return temporary placement area A3) shown in FIG.

実装動作処理部30aは、実装ヘッド8によって部品供給部4から取り出した電子部品Pを基板3に実装するための動作を制御する処理を行う。配置前仮置き位置割当て処理部30bは、ピン配置データ32、仮置き位置データ33に基づいて、配置前仮置きエリアA2において、X方向の座標原点Oから近接した順に設定された仮置き位置TPのそれぞれに、下受けエリアA1に配置される複数の下受けピン22を個別に割り当てる処理を実行する。処理実行結果は、配置前仮置き位置割当てデータ34として記憶部31に記憶される。同様に返戻後仮置き位置割当て処理部30cは、ピン配置データ32、仮置き位置データ33に基づいて、返戻後仮置きエリアA3において、X方向の座標原点Oから近接した順に設定された仮置き位置TPのそれぞれに、返戻される複数の下受けピン22を個別に割り当てる処理を行う。処理実行結果は、返戻後仮置き位置割当てデータ35として記憶部31に記憶される。   The mounting operation processing unit 30 a performs a process of controlling an operation for mounting the electronic component P taken out from the component supply unit 4 on the substrate 3 by the mounting head 8. The temporary placement position assignment processing unit 30b before placement is set based on the pin placement data 32 and the temporary placement position data 33 in the temporary placement position TP set in the order close to the coordinate origin O in the X direction in the temporary placement area A2 before placement. A process of individually allocating a plurality of receiving pins 22 arranged in the receiving area A1 is performed on each of them. The processing execution result is stored in the storage unit 31 as pre-placement temporary placement position assignment data 34. Similarly, the post-return temporary placement position assignment processing unit 30c is set based on the pin arrangement data 32 and the temporary placement position data 33 in the temporary placement area A3 after return, which is set in the order close to the coordinate origin O in the X direction. A process of individually assigning a plurality of returned receiving pins 22 to each position TP is performed. The processing execution result is stored in the storage unit 31 as the temporary placement position assignment data 35 after returning.

配置実行処理部30dは、配置前仮置き位置割当てデータ34に基づき、配置前仮置きエリアA2に仮置きされた複数の下受けピン22を、下受けエリアA1内のそれぞれに対応した配置位置APに順次移動させるための処理を行う。返戻実行処理部30eは、下受けエリアA1に配置された複数の下受けピン22を、返戻後仮置きエリアA3のそれぞれの仮置き位置TPに順次移動させる処理を行う。   Based on the pre-placement temporary placement position assignment data 34, the placement execution processing unit 30d assigns the plurality of bottom receiving pins 22 temporarily placed in the pre-placement temporary placement area A2 to the placement positions AP corresponding to the respective placement within the placement area A1. A process for sequentially moving to each other is performed. The return execution processing unit 30e performs a process of sequentially moving the plurality of receiving pins 22 arranged in the receiving area A1 to the temporary setting positions TP in the temporary setting area A3 after returning.

機構駆動部36は、制御部30によって制御されることにより、基板搬送機構2、実装ヘッド8、Y軸移動テーブル6,X軸移動テーブル7よりなるヘッド移動機構を駆動する。これにより、基板3への部品実装動作、基板搬送機構2の基板下受け機構2cにおける下受けピン22の配置変更動作が実行される。認識処理部37は、基板認識カメラ10、部品認識カメラ11の撮像結果を認識処理する。基板3への部品実装動作においては、これらの認識処理結果に基づいて検出された位置誤差が補正される。   The mechanism driving unit 36 is controlled by the control unit 30 to drive a head moving mechanism including the substrate transport mechanism 2, the mounting head 8, the Y-axis moving table 6, and the X-axis moving table 7. Thereby, the component mounting operation on the board 3 and the arrangement changing operation of the lower receiving pins 22 in the lower board receiving mechanism 2c of the board conveying mechanism 2 are executed. The recognition processing unit 37 performs recognition processing on the imaging results of the board recognition camera 10 and the component recognition camera 11. In the component mounting operation on the board 3, the position error detected based on the recognition processing results is corrected.

次に,図5、図7を参照して、配置前仮置き位置割当て処理部30b、返戻後仮置き位置割当て処理部30cによって実行される仮置き位置割当て処理の実際例について説明する。図7(a)は、図5(a)に示す下受けエリアA1におけるピン配置に対応する配置前仮置き位置割当てデータ34を示している。ここでは、配置位置欄34aに示す配置位置AP1〜AP6のそれぞれに、仮置き位置欄34bに示される仮置き位置TP1〜TP6を対応させている。そしてさらに移動実行順34cを設定することにより、個別の下受けピン22の移動順序を規定している。ここでは配置前仮置き位置割当て処理部30bは、仮置き位置TPが座標原点Oから近接する順序と、下受けエリアA1に配置される下受けピン22の配置位置APのX方向の座標値xが小さい順序とを対応させて、仮置き位置TPの割り当てを実行する。   Next, an actual example of the temporary placement position assignment process executed by the pre-placement temporary placement position assignment processing unit 30b and the post-return temporary placement position assignment processing unit 30c will be described with reference to FIGS. FIG. 7A shows pre-placement temporary placement position assignment data 34 corresponding to the pin placement in the receiving area A1 shown in FIG. Here, the temporary placement positions TP1 to TP6 shown in the temporary placement position column 34b correspond to the placement positions AP1 to AP6 shown in the placement position column 34a. Further, by setting the movement execution order 34c, the movement order of the individual support pins 22 is defined. Here, the pre-placement temporary placement position allocation processing unit 30b determines the order in which the temporary placement position TP approaches the coordinate origin O and the coordinate value x in the X direction of the placement position AP of the support pin 22 placed in the support area A1. The temporary placement position TP is assigned by associating with the order with the smallest.

すなわち座標原点Oに最も近接する仮置き位置TP1に、最も小さいX方向の座標値x1に対応する配置位置AP1を割り当て、次いで2番目に近接する仮置き位置TP2に2番目に小さいX方向の座標値x2に対応する配置位置AP2を割り当てる。次は3番目に近接する仮置き位置TP3を対象とする際には、座標値x3、x4のいずれもが3番目に小さいX方向の座標値に該当することから、以下のように取り扱う。   That is, the placement position AP1 corresponding to the smallest coordinate value x1 in the X direction is assigned to the temporary placement position TP1 closest to the coordinate origin O, and then the second smallest X direction coordinate is assigned to the second closest temporary placement position TP2. An arrangement position AP2 corresponding to the value x2 is assigned. Next, when the temporary placement position TP3 that is the third closest is targeted, both coordinate values x3 and x4 correspond to the coordinate value in the X direction that is the third smallest, and are handled as follows.

すなわち、配置前仮置き位置割り当てにおいて、X方向(第1方向)の座標値が等しい複数の配置位置AP(ここでは配置位置AP3,AP4)が存在する場合には、これらの配置位置APのうちY方向(第2方向)の座標値yが大きい順に仮置き位置を対応させる。これにより、大きい方の座標値y3に対応する配置位置AP3が、仮置き位置TP3に対して割り当てられ、配置位置AP4が仮置き位置TP4に対して割り当てられる。そしてX方向の座標値x5、x6が等しい配置位置AP5,AP6についても、同様の取り扱いがなされ、大きい方の座標値y5に対応する配置位置AP5が、仮置き位置TP5に対して割り当てられ、配置位置AP6が仮置き位置TP6に対して割り当てられる。   That is, in the temporary placement position allocation before placement, when there are a plurality of placement positions AP (here, placement positions AP3, AP4) having the same coordinate value in the X direction (first direction), among these placement positions AP The temporary placement positions are made to correspond in descending order of the coordinate value y in the Y direction (second direction). Thereby, the arrangement position AP3 corresponding to the larger coordinate value y3 is assigned to the temporary placement position TP3, and the arrangement position AP4 is assigned to the temporary placement position TP4. The same processing is performed for the placement positions AP5 and AP6 having the same X-direction coordinate values x5 and x6, and the placement position AP5 corresponding to the larger coordinate value y5 is assigned to the temporary placement position TP5. The position AP6 is assigned to the temporary placement position TP6.

次いで、移動実行順34cが設定される。ここでは、配置位置APにおいてY方向の座標値yが大きい下受けピン22から順に移動を実行するようにしている。すなわち、配置位置AP1、配置位置AP5、配置位置AP3、配置位置AP2の順序((1)〜(4)番目)で移動が実行される。そして座標値y4,y6が等しい配置位置AP4,配置位置AP6については、以下のように取り扱われる。すなわちY方向の座標値yが等しい複数の配置位置APが存在する場合には、これらの配置位置APのうちX方向の座標値が大きい下受けピン22から順に移動を実行する。これにより、大きい方の座標値x6に対応する配置位置AP6が、(5)番目、次いで配置位置AP4が(6)番目に移動の対象となる。そして配置実行処理部30dが下受けピン22の配置を実行させる際には、配置前仮置き位置割当てデータ34に示す移動実行順34cに基づいて、下受けピン22の移動を実行する。   Next, the movement execution order 34c is set. Here, the movement is executed in order from the receiving pin 22 having the largest coordinate value y in the Y direction at the arrangement position AP. That is, the movement is executed in the order of the placement position AP1, the placement position AP5, the placement position AP3, and the placement position AP2 ((1) to (4) th). The arrangement positions AP4 and AP6 having the same coordinate values y4 and y6 are handled as follows. That is, when there are a plurality of arrangement positions AP having the same Y-direction coordinate value y, the movement is executed sequentially from the receiving pins 22 having the largest X-direction coordinate value among these arrangement positions AP. As a result, the arrangement position AP6 corresponding to the larger coordinate value x6 is the (5) th, and then the arrangement position AP4 is the (6) th movement target. When the placement execution processing unit 30d executes the placement of the receiving pins 22, the placement pins 22 are moved based on the movement execution order 34c shown in the temporary placement position assignment data 34 before placement.

次に、図7(b)は、図5(a)に示す下受けエリアA1におけるピン配置に対応する返戻後仮置き位置割当てデータ35を示している。ここでも配置前仮置き位置割当てデータ34と同様に、配置位置欄35aに示す配置位置AP1〜AP6のそれぞれに、仮置き位置欄35bに示される仮置き位置TP〜TP6を対応させている。そしてさらに移動実行順35cを設定することにより、個別の下受けピン22の移動順序を規定している。またここでも配置前仮置き位置割当て処理部30bと同様に、返戻後仮置き位置割当て処理部30cは、仮置き位置TPが座標原点Oから近接する順序と、配置される下受けピン22の配置位置APのX方向の座標値xが小さい順序とを対応させて、仮置き位置TPの割り当てを実行する。   Next, FIG. 7B shows post-return temporary placement position allocation data 35 corresponding to the pin arrangement in the receiving area A1 shown in FIG. Here, as with the pre-placement temporary placement position assignment data 34, the placement positions AP1 to AP6 shown in the placement position column 35a are associated with the temporary placement positions TP to TP6 shown in the temporary placement position column 35b. Further, by setting the movement execution order 35c, the movement order of the individual support pins 22 is defined. In this case, similarly to the pre-placement temporary placement position assignment processing unit 30b, the post-return temporary placement position assignment processing unit 30c is arranged so that the temporary placement position TP approaches the coordinate origin O and the placement of the receiving pins 22 to be placed. The allocation of the temporary placement position TP is executed in association with the order of the coordinate value x in the X direction of the position AP in ascending order.

すなわち座標原点Oに最も近接する仮置き位置TP1に、最も小さいX方向の座標値x1に対応する配置位置AP1を割り当て、次いで2番目に近接する仮置き位置TP2に2番目に小さいX方向の座標値x2に対応する配置位置AP2を割り当てる。次は3番目に近接する仮置き位置TP3を対象とする際には、座標値x3、x4のいずれもが3番目に小さいX方向の座標値に相当することから、以下のように取り扱う。   That is, the placement position AP1 corresponding to the smallest coordinate value x1 in the X direction is assigned to the temporary placement position TP1 closest to the coordinate origin O, and then the second smallest X direction coordinate is assigned to the second closest temporary placement position TP2. An arrangement position AP2 corresponding to the value x2 is assigned. Next, when the temporary placement position TP3 that is the third closest is targeted, since both coordinate values x3 and x4 correspond to the third smallest coordinate value in the X direction, they are handled as follows.

すなわち、返戻後仮置き位置割り当てにおいて、X方向(第1方向)の座標値が等しい複数の配置位置AP(ここでは配置位置AP3,AP4)が存在する場合には、これらの配置位置APのうちY方向(第2方向)の座標値yが大きい順に仮置き位置を対応させる。これにより、大きい方の座標値y3に対応する配置位置AP3が、仮置き位置TP3に対して割り当てられ、配置位置AP4が仮置き位置TP4に対して割り当てられる。そしてX方向の座標値x5、x6が等しい配置位置AP5,AP6についても、同様の取り扱いがなされ、大きい方の座標値y5に対応する配置位置AP5が、仮置き位置TP5に対して割り当てられ、配置位置AP6が仮置き位置TP6に対して割り当てられる。   That is, when there are a plurality of placement positions AP (here, placement positions AP3 and AP4) having the same coordinate value in the X direction (first direction) in the temporary placement position assignment after return, of these placement positions AP, The temporary placement positions are made to correspond in descending order of the coordinate value y in the Y direction (second direction). Thereby, the arrangement position AP3 corresponding to the larger coordinate value y3 is assigned to the temporary placement position TP3, and the arrangement position AP4 is assigned to the temporary placement position TP4. The same processing is performed for the placement positions AP5 and AP6 having the same X-direction coordinate values x5 and x6, and the placement position AP5 corresponding to the larger coordinate value y5 is assigned to the temporary placement position TP5. The position AP6 is assigned to the temporary placement position TP6.

次いで、移動実行順34cが設定される。ここでは、配置位置APにおいてY方向の座標値yが小さい下受けピン22から順に移動を実行するようにしている。ここで、Y方向の座標値yが最も小さい配置位置APは、配置位置AP4、配置位置APの2つが存在することから、以下のように取り扱われる。すなわちY方向の座標値yが等しい複数の配置位置APが存在する場合には、これらの配置位置APのうちX方向の座標値が小さい下受けピン22から順に移動を実行する。これにより、小さい方の座標値x4に対応する配置位置AP4が、(1)番目、次いで配置位置AP6が(2)番目に移動の対象となる。そして残余の配置位置APについては、座標値yが小さい順に、配置位置AP2、配置位置AP3、配置位置AP5、配置位置AP1の順序((3)〜(6)番目)で下受けピン22の移動が実行される。そして返戻実行処理部30eが下受けピン22の返戻を実行させる際には、返戻後仮置き位置割当てデータ35に示す移動実行順35cに基づいて、下受けピン22の移動を実行する。   Next, the movement execution order 34c is set. Here, the movement is executed in order from the receiving pin 22 having a small coordinate value y in the Y direction at the arrangement position AP. Here, since there are two arrangement positions AP4 and AP, the arrangement position AP having the smallest coordinate value y in the Y direction is handled as follows. That is, when there are a plurality of arrangement positions AP having the same Y-direction coordinate value y, the movement is executed in order from the receiving pin 22 having the smallest X-direction coordinate value among these arrangement positions AP. As a result, the placement position AP4 corresponding to the smaller coordinate value x4 is the (1) th, and then the placement position AP6 is the (2) th movement target. For the remaining arrangement position AP, the movement of the receiving pin 22 in the order of the arrangement position AP2, the arrangement position AP3, the arrangement position AP5, and the arrangement position AP1 ((3) to (6) th) in ascending order of the coordinate value y. Is executed. When the return execution processing unit 30e executes the return of the receiving pins 22, the movement of the receiving pins 22 is executed based on the movement execution order 35c shown in the temporary placement position assignment data 35 after returning.

次に図8および各図を参照して、電子部品実装装置1において、基板3を下面側から下受けして支持する複数の下受けピン22を、下受けベース部21に設定された下受けエリアA1の任意の位置に配置する下受けピンの配置方法およびこれらの下受けピンを下受けエリアA1から取り出して返戻する下受けピンの返戻方法について説明する。   Next, referring to FIG. 8 and each drawing, in the electronic component mounting apparatus 1, a plurality of lower receiving pins 22 for receiving and supporting the substrate 3 from the lower surface side are set to the lower receiving base portion 21. A description will be given of a method for arranging the receiving pins arranged at an arbitrary position in the area A1 and a method for returning the receiving pins that are taken out from the receiving area A1 and returned.

まず、これらの作業実行に先立って、配置前仮置き位置割当て処理部30b、返戻後仮置き位置割当て処理部30cによって、図7に示す配置前仮置き位置割当てデータ34、返戻後仮置き位置割当てデータ35を作成する(配置前仮置き位置割当て工程、返戻後仮置き位置割当て工程)。作成された配置前仮置き位置割当てデータ34、返戻後仮置き位置割当てデータ35は、記憶部31に記憶される。この配置前仮置き位置割当て工程、返戻後仮置き位置割当て工程においては、仮置き位置TPの座標原点Oから近接した順序と、配置または返戻される複数の下受けピン22において配置位置APのX方向の座標値xが小さい順序とを対応させて、割り当てを実行する。   First, prior to execution of these operations, the pre-placement temporary placement position assignment processing unit 30b and the post-return temporary placement position assignment processing unit 30c perform pre-placement temporary placement position assignment data 34 and post-return temporary placement position assignment shown in FIG. Data 35 is created (temporary placement position assignment step before placement, temporary placement position assignment step after return). The created pre-placement temporary placement position assignment data 34 and post-return temporary placement position assignment data 35 are stored in the storage unit 31. In the pre-placement temporary placement position assignment step and the post-return temporary placement position assignment step, the order of the temporary placement position TP close to the coordinate origin O and the X of the placement position AP in the plurality of receiving pins 22 to be placed or returned. The assignment is executed in association with the order in which the coordinate value x of the direction is small.

次いで、ピン配置作業の前準備として、図4に示すピン収納部15から必要数の下受けピン22を、実装ヘッド8によって下受けベース部21の配置前仮置きエリアA2に設定された仮置き位置TPに移載する。なお、基板種の変更に伴う段取り替え作業におけるピン配置作業など、既に配置前仮置きエリアA2に必要数の下受けピン22が載置されている場合には、新たに下受けピン22を移載する必要はない。   Next, as a pre-preparation for the pin placement work, the required number of lower receiving pins 22 from the pin storage portion 15 shown in FIG. 4 is temporarily placed in the temporary placement area A2 before placement of the lower receiving base portion 21 by the mounting head 8. Transfer to position TP. Note that if the required number of receiving pins 22 has already been placed in the pre-placement temporary placement area A2, such as a pin placement operation in a setup change operation accompanying a change in the substrate type, the receiving pins 22 are newly moved. There is no need to list.

この後、配置実行処理部30dが配置前仮置き位置割当てデータ34を参照することにより、配置前仮置きエリアA2において割り当てられた仮置き位置TP1〜TP6に仮置きされた複数の下受けピン22を、実装ヘッド8によって順次下受けエリアA1の配置位置AP1〜AP6に移動させる(配置実行工程)。この配置実行工程においては、配置位置APにおいてY方向の座標値yが大きい下受けピン22から順に、移動を実行する。これにより、配置前仮置きエリアA2から隔たった順に下受けピン22が移動することになり、下受けエリアA1には位置済みの下受けピン22に移動途中の下受けピン22が接触するピン相互の干渉を防止することができる。   Thereafter, the placement execution processing unit 30d refers to the pre-placement temporary placement position assignment data 34, whereby a plurality of the receiving pins 22 temporarily placed in the temporary placement positions TP1 to TP6 assigned in the pre-placement temporary placement area A2. Are sequentially moved to the arrangement positions AP1 to AP6 of the receiving area A1 by the mounting head 8 (arrangement execution step). In this arrangement execution step, the movement is executed in order from the receiving pin 22 having the largest coordinate value y in the Y direction at the arrangement position AP. As a result, the lower receiving pins 22 move in the order separated from the pre-placement temporary placement area A2, and in the lower receiving area A1, the lower receiving pins 22 in contact with the already positioned lower receiving pins 22 contact each other. Interference can be prevented.

すなわち、図8(a)に示すように、まず(1)番目に仮置き位置TP1に仮置きされた下受けピン22を最もY方向の座標値y1が大きい配置位置AP1に移動させる。次いで、(2)番目として、仮置き位置TP5に仮置きされた下受けピン22をY方向の座標値y5が次に大きい配置位置AP5に移動させる。次いで同様に、仮置き位置TP3に仮置きされた下受けピン22を配置位置AP3に、仮置き位置TP2に仮置きされた下受けピン22を配置位置AP2に、それぞれ(3)番目、(4)番目に移動させる。   That is, as shown in FIG. 8A, first, the lower receiving pin 22 temporarily placed at the temporary placement position TP1 (1) is moved to the placement position AP1 having the largest coordinate value y1 in the Y direction. Next, as (2) th, the receiving pin 22 temporarily placed at the temporary placement position TP5 is moved to the placement position AP5 having the next largest coordinate value y5 in the Y direction. Similarly, the lower receiving pin 22 temporarily placed at the temporary placement position TP3 is placed at the placement position AP3, and the lower placement pin 22 temporarily placed at the temporary placement position TP2 is placed at the placement position AP2, respectively. ) Move to the second.

そしてY方向の座標値y4,y6が等しい配置位置AP4、配置位置AP6については、配置位置APのX方向の座標値が大きい下受けピン22から順に移動を実行する。すなわちここでは座標値x4よりも座標値x6が大きいことから、仮置き位置TP6に仮置きされた下受けピン22を配置位置AP6に、次いで仮置き位置TP4に仮置きされた下受けピン22を配置位置AP4に、それぞれ(5)番目、(6)番目に移動させ、図5(a)に示すピン配置が完了する。   The placement position AP4 and the placement position AP6 having the same coordinate values y4 and y6 in the Y direction are sequentially moved from the receiving pin 22 having the largest coordinate value in the X direction of the placement position AP. That is, here, since the coordinate value x6 is larger than the coordinate value x4, the lower support pin 22 temporarily placed at the temporary placement position TP6 is placed at the placement position AP6, and then the lower placement pin 22 temporarily placed at the temporary placement position TP4. The pins are moved to the placement position AP4 to the (5) th and (6) th, respectively, and the pin placement shown in FIG. 5A is completed.

この後、当該ピン配置にしたがって配置された複数の下受けピン22によって基板3を下受けした状態で、部品実装作業が実行される。そして所定ロット数の生産が完了したならば、このピン配置を新たな基板3に対応したピン配置に変更するために、下受けエリアA1に配置された下受けピン22を返戻後仮置きエリアA3に移動させる返戻動作が実行される。   Thereafter, the component mounting operation is performed in a state where the board 3 is received by the plurality of receiving pins 22 arranged according to the pin arrangement. When the production of the predetermined lot number is completed, in order to change this pin arrangement to the pin arrangement corresponding to the new substrate 3, the lower receiving pins 22 arranged in the lower receiving area A1 are returned to the temporary placement area A3. The return operation to move to is executed.

すなわち返戻実行処理部30eが返戻後仮置き位置割当てデータ35を参照することにより、下受けエリアA1に配置された複数の下受けピン22を、返戻後仮置きエリアA3に割り当てられた仮置き位置TPに順次移動させる(返戻実行工程)。この返戻実行工程においては、配置位置APにおいてY方向の座標値yが小さい下受けピン22から順に、移動を実行する。これにより、返戻後仮置きエリアA3に近接した順に下受けピン22が移動することになり、下受けエリアA1においてまだ返戻されていない下受けピン22に、返戻後仮置きエリアA3へ移動途中の下受けピン22が接触するピン相互の干渉を防止することができる。   That is, the return execution processing unit 30e refers to the post-return temporary placement position assignment data 35 so that the plurality of lower support pins 22 arranged in the lower support area A1 are temporarily placed in the post-return temporary placement area A3. Move sequentially to TP (return execution step). In this return execution step, the movement is executed in order from the receiving pin 22 having the smallest coordinate value y in the Y direction at the arrangement position AP. As a result, the receiving pins 22 move in the order of proximity to the temporary placement area A3 after returning to the receiving pins 22 that have not yet been returned in the receiving area A1, and are in the process of moving to the temporary placing area A3 after returning. It is possible to prevent interference between pins that contact the lower receiving pins 22.

図8(b)に示す例においては、最もY方向の座標値yが小さい配置位置APとして、配置位置AP4、配置位置AP6が存在することから、配置位置のX方向の座標値が小さい下受けピン22から順に移動を実行する。すなわちここでは座標値x6よりも座標値x4が小さいことから、配置位置AP4に配置された下受けピン22を仮置き位置TP4に、次いで配置位置AP6に配置された下受けピン22を仮置き位置TP6に、それぞれ(1)番目、(2)番目に移動させる。   In the example shown in FIG. 8B, the arrangement position AP4 and the arrangement position AP6 exist as the arrangement position AP having the smallest coordinate value y in the Y direction. The movement is executed sequentially from the pin 22. That is, here, since the coordinate value x4 is smaller than the coordinate value x6, the lower receiving pin 22 arranged at the arrangement position AP4 is set to the temporary placement position TP4, and then the lower placement pin 22 arranged at the arrangement position AP6 is set to the temporary placement position. The TP6 is moved to the (1) th and (2) th respectively.

この後、配置位置APにおいてY方向の座標値yが小さい順に下受けピン22の移動が反復される。すなわち、配置位置AP2に配置された下受けピン22を仮置き位置TP2に、配置位置AP3に配置された下受けピン22を仮置き位置TP3に、それぞれ(3)番目、(4)番目に移動させる。次いで、配置位置AP5に配置された下受けピン22を仮置き位置TP5に、配置位置AP1に配置された下受けピン22を仮置き位置TP1に、それぞれ(5)番目、(6)番目に移動させて、下受けエリアA1からの下受けピン22の返戻作業を終了する。   Thereafter, the movement of the receiving pins 22 is repeated in the order of increasing coordinate value y in the Y direction at the arrangement position AP. That is, the lower receiving pin 22 arranged at the arrangement position AP2 is moved to the temporary placement position TP2, and the lower receiving pin 22 arranged at the arrangement position AP3 is moved to the temporary placement position TP3, respectively (3) th and (4) th. Let Next, the lower receiving pin 22 arranged at the arrangement position AP5 is moved to the temporary placement position TP5, and the lower receiving pin 22 arranged at the arrangement position AP1 is moved to the temporary placement position TP1, respectively (5) th and (6) th. Thus, the returning operation of the receiving pin 22 from the receiving area A1 is completed.

上記説明したように、本実施の形態に示す電子部品実装装置および下受けピンの配置方法ならびに下受けピンの返戻方法においては、基板下受け機構2cの下受けベース部21に下受けピン22が任意の位置に配置される下受けエリアA1とともに、配置前の複数の下受けピン22が仮置きされる配置前仮置きエリアA2、返戻後の複数の下受けピン22が仮置きされる返戻後仮置きエリアA3を設定し、配置前仮置きエリアA2、返戻後仮置きエリアA3における下受けピン22の仮置き位置TPを,下受けエリアA1における下受けピン22の配置位置APに応じて、下受けピン22の移動におけるピン相互の干渉が生じない条件を勘案して予め割り当てておくようにしている。   As described above, in the electronic component mounting apparatus, the receiving pin arrangement method, and the receiving pin return method shown in the present embodiment, the receiving pin 22 is provided on the receiving base portion 21 of the substrate receiving mechanism 2c. A pre-placement temporary placement area A2 in which a plurality of bottom support pins 22 before placement is temporarily placed together with a placement area A1 placed at an arbitrary position, and after a return in which a plurality of bottom support pins 22 after return are provisionally placed. The temporary placement area A3 is set, and the temporary placement position TP of the lower receiving pin 22 in the temporary placement area A2 before placement and the temporary placement area A3 after return is set according to the placement position AP of the lower placement pin 22 in the lower receiving area A1. In consideration of a condition in which interference between pins in the movement of the receiving pin 22 does not occur, the assignment is made in advance.

これにより、下受けエリアA1へ下受けピン22を配置する配置実行工程、下受けエリアA1から下受けピン22を返戻する返戻実行工程における下受けピン移動時の干渉を有効に防止することができる。特に、下受けピン22を下受けベース部21の任意位置に配置する方式において、ピン相互の間隔が狭くなってピン移動時の干渉が生じやすくなっている場合にあっても、下受けピン22の移動経路や順序を適切に設定して、移動時のピン相互の干渉を確実に防止することができる。   Thereby, the interference at the time of movement of the receiving pin can be effectively prevented in the arrangement executing step of arranging the receiving pin 22 in the receiving area A1 and the return executing step of returning the receiving pin 22 from the receiving area A1. . In particular, in the system in which the lower receiving pins 22 are arranged at arbitrary positions on the lower receiving base portion 21, even when the distance between the pins is narrow and interference during pin movement is likely to occur, the lower receiving pins 22 By appropriately setting the movement path and order of the pins, it is possible to reliably prevent interference between pins during movement.

したがって、従来技術において、下受けピン相互の干渉を防止するために採用されていたピン移動形態、すなわちピン移動時の昇降ストロークを下受けピン高さ以上に設定することに起因する不都合、例えば移載ヘッドのストロークを過大に設定することによる設備コスト増大や、昇降ストロークの増大に伴う作業時間の遅延によるタクトロスなどを防止して、下受けピン22の配置作業や返戻作業を効率化することができる。   Therefore, in the prior art, the pin movement form employed to prevent interference between the receiving pins, that is, inconvenience caused by setting the lifting stroke at the time of moving the pin to be higher than the height of the receiving pin, for example, shifting. It is possible to prevent the increase in equipment cost by setting the stroke of the mounting head excessively and the tact loss due to the delay in work time due to the increase in the lifting stroke, thereby improving the efficiency of the placement work and return work of the receiving pins 22. it can.

本発明の電子部品実装装置および下受けピンの配置方法ならびに下受けピンの返戻方法は、下受けピンの配置作業や返戻作業を効率化することができるという効果を有し、複数の下受けピンによって下面を支持された基板に電子部品を実装する電子部品実装分野において有用である。   INDUSTRIAL APPLICABILITY The electronic component mounting apparatus, the receiving pin arrangement method, and the receiving pin return method of the present invention have the effect that the arrangement operation and the returning operation of the receiving pin can be made efficient, and a plurality of receiving pins are provided. This is useful in the field of electronic component mounting where an electronic component is mounted on a substrate whose lower surface is supported by the above.
