While being guided to the surface 5 10 0, it is turned in a direction away from the locked surface 5 10 0 in a direction perpendicular to the advance / retreat direction. The rotation locus of the rotation locking member 472 is shown by a two-dot chain line.
[0062] それにより他方の係合部 4 8 4は第六案内面 5 1 6に係合し、 それに沿つ て移動する。 第六案内面 5 1 6の、 回動係止部材 4 7 2の回動軸線からの距 離は、 第一案内面 5 0 0のその回動軸線からの距離とほぼ同じであるが、 第 一案内面 5 0 0とは逆の側から係合部 4 8 4に接触するため、 係合部 4 8 4 の方が係合部 4 8 2より回動角度が小さく、 回動係止部材 4 7 2が弾性変形 させられ、 アーム部 4 7 8がアーム部 4 8 0に対して図 2 2 (b)において時計 方向に相対回動する向きにねじられる。 便宜上、 このねじり方向を正方向と する。 ねじりがない場合の係合部 4 8 4の位置を図 2 2 (C)に二点鎖線の円の みで示す。 そして、 係合部 4 8 4は、 図 2 2 (C)に示すように、 係合部 4 8 2 が第一案内面 5 0 0に案内されている状態において第三案内溝部 5 2 6に嵌 入し、 第三案内溝部 5 2 6に案内され、 回動を規制されつつ被係止部材 4 7 0に対して相対移動させられる。 そのため、 係合部 4 8 2は第一案内面 5 0 0の端まで移動したとき、 回動係止部材 4 7 2の弾性復元力により逆方向に 回動させられて第四案内面 5 0 6に係合し、 第二案内面 5 0 2の真下に位置 させられる。 支持ピン把持装置 2 5 2が下降端位置へ下降させられた状態で は、 図 2 2 (C)に示すように、 係合部 4 8 2は第四案内面 5 0 6に係合し、 係 合部 4 8 4は第三案内溝部 5 2 6の下部に嵌入した状態となる。 なお、 案内 部 4 9 0, 4 9 2は互いに背中合わせに設けられているが、 図 2 2, 図 2 3 では、 それらが並んだ状態で図示されており、 回動係止部材 4 7 2の回動方 向は逆向きに図示される。 [0062] Thereby, the other engaging portion 484 is engaged with the sixth guide surface 5 16 and moves along the sixth guide surface 5 16. The distance of the sixth guide surface 5 16 from the rotation axis of the rotation locking member 472 is substantially the same as the distance of the first guide surface 500 from the rotation axis. Since the engaging portion 484 is contacted from the side opposite to the one guide surface 500, the engaging portion 484 has a smaller rotation angle than the engaging portion 482, and the rotation locking member The arm portion 472 is elastically deformed, and the arm portion 478 is twisted in a direction to rotate clockwise relative to the arm portion 480 in FIG. 22B. For convenience, this torsion direction is defined as the forward direction. The position of the engagement portion 484 when there is no torsion is shown in FIG. Then, as shown in FIG. 22 (C), the engaging portion 484 is formed in the third guide groove portion 526 in a state where the engaging portion 482 is guided by the first guide surface 500. It is guided by the third guide groove portion 526, and is relatively moved with respect to the locked member 470 while its rotation is restricted. Therefore, the engaging portion 4 82 is the first guide surface 50 When it has moved to the end of 0, it is rotated in the opposite direction by the elastic restoring force of the rotation locking member 472 and engages with the fourth guide surface 506, and directly below the second guide surface 502. Is located at In a state where the support pin gripping device 25 2 is lowered to the lower end position, as shown in FIG. 22 (C), the engaging portion 48 2 is engaged with the fourth guide surface 50 6, The engaging portion 484 is fitted into the lower portion of the third guide groove portion 526. Although the guide portions 49 0 and 49 2 are provided back to back with each other, they are shown side by side in FIGS. 22 and 23, and the rotation locking members 47 2 The direction of rotation is illustrated in the opposite direction.
支持ピン把持装置 2 5 2は、 把持装置本体 3 6 0が下降端位置へ下降させ られた後、 上昇端位置に向かって上昇させられる。 この際、 進退部材 3 6 4 はスプリング 3 7 4の付勢によリ支持ピン 2 5 0の先端部と係合する状態に 保たれ、 スプリング 3 7 4が伸長しつつ、 把持装置本体 3 6 0が進退部材 3 6 4に対して上昇し、 図 2 2 (d)に示すように、 回動係止部材 4 7 2が上昇さ せられ、 一対の係合部 4 8 2, 4 8 4がそれぞれ、 第四案内面 5 0 6および 第三案内溝部 5 2 6により案内されて被係止面 5 1 0, 5 3 0側へ移動させ られる。 そして、 係合部 4 8 2が第二案内面 5 0 2に係合し、 案内され、 や がて図 2 2 (e)に示すように、 被係止面 5 1 0に係合する。 この際、 係合部 4 8 2は、 係合部 4 8 4が第三案内溝部 5 2 6内に嵌入している状態において 第二案内面 5 0 2に係合する。 そのため、 係合後は回動係止部材 4 7 2が弾 性変形させられて逆方向にねじられ、 係合部 4 8 4が第三案内溝部 5 2 6か ら抜け出したとき、 回動係止部材 4 7 2の弾性復元力によって被係止面 5 3 0側へ移動させられて被係止面 5 3 0のほぼ真下に位置する。 この時期には 、 係合部 4 8 2も被係止面 5 1 0のほぼ真下に位置している。 したがって、 その状態から支持ピン把持装置 2 5 2がさらに上昇させられ、 進退部材 3 6 4が相対的に下降させられれば、 係合部 4 8 2, 4 8 4それぞれ被係止面 5 1 0, 5 3 0に係合する。 すなわち、 進退部材 3 6 4が回動係止部材 4 7 2 を介して把持装置本体 3 6 0に係止され、 図 1 8に示すように作用位置に保 持され、 把持爪群 3 6 2は作用レバー 4 4 0が把持爪 3 9 4に係合し、 閉状 態に保たれて支持ピン 2 5 0を把持し続ける。 The support pin gripping device 255 is raised toward the rising end position after the gripping device main body 360 is lowered to the lower end position. At this time, the advancing / retreating member 365 is held in a state of being engaged with the distal end of the support pin 250 by the bias of the spring 374, and the spring 374 expands while the gripping device main body 356 is held. 0 rises with respect to the advance / retreat member 364, and as shown in FIG. 22 (d), the rotation locking member 472 is raised, and the pair of engaging portions 4882, 4884 Are guided by the fourth guide surface 506 and the third guide groove portion 526, respectively, and are moved to the locked surfaces 5110 and 530, respectively. Then, the engaging portion 482 is engaged with and guided by the second guide surface 502, and is eventually engaged with the locked surface 5110 as shown in FIG. 22 (e). At this time, the engaging portion 482 is engaged with the second guide surface 502 while the engaging portion 484 is fitted in the third guide groove portion 526. Therefore, after the engagement, the rotation locking member 472 is elastically deformed and twisted in the opposite direction, and when the engagement portion 484 comes out of the third guide groove portion 526, The locking member 472 is moved toward the locked surface 5300 by the elastic restoring force of the locking member 472, and is located almost directly below the locked surface 5330. At this time, the engaging portion 482 is also located almost directly below the locked surface 5110. Therefore, from this state, if the support pin gripping device 25 2 is further raised and the advance / retreat member 36 4 is relatively lowered, the engagement surfaces 48 2 and 48 4 are respectively engaged with the locked surfaces 5 10 , 530. That is, the advancing / retreating member 365 is locked to the gripping device main body 360 via the rotation locking member 472, and is held in the operating position as shown in FIG. Is closed when the action lever 4 40 engages the gripper claw 3 94 The support pin 250 is kept being held in the state.
支持ピン把持装置 2 5 2は、 この状態から更に上昇させられるが、 進退部 材 3 6 4が把持装置本体 3 6 0と共に上昇させられ、 把持爪群 3 6 2および 支持ピン 2 5 0が上昇させられる。 把持爪 3 9 4 , 3 9 6は、 爪部 4 1 0, 4 1 2が環状の係合部 3 2 9に係合してピン部材 2 7 4に引張力を加え、 基 台 2 7 2に対して上昇させる。 その上昇途中に、 まず、 C形部材 3 0 4の係 合部 3 1 0が突部 3 3 6に係合する。 そのため、 図 2 1 (a)に示すように、 磁 石保持部材 3 3 0が、 底面 3 3 5の突部 3 3 8側の部分と底板 2 9 2との当 接部を中心とし、 磁気吸引力に杭して傾けられ、 ピン支持台 2 5 4に対して 斜めに離間させられて磁気吸引力が減少させられる。 ピン部材 2 7 4に加え られる引張力が永久磁石部 3 3 4に、 永久磁石部 3 3 4を傾動させる力とし て伝達されるのである。 この際、 永久磁石部 3 3 4の中央に集中的に作用す ると考えることができる磁気吸引力の合力に、 係合部 3 1 0が突部 3 3 6に 加える力と、 底板 2 9 2が磁石保持部材 3 3 0の底面 3 3 5の突部 3 3 8側 の部分に加える力とで対抗すればよいのであり、 しかも、 磁気吸引力の合力 から、 係合部 3 1 0と突部 3 3 8との接触点までの水平距離 (底板 2 9 2に 平行な方向の距離) が、 底面 3 3 5の突部 3 3 8側の部分と底板 2 9 2との 接触点までの水平距離の 2倍弱であるため、 係合部 3 1 0が突部 3 3 6に加 えるべき力は、 磁気吸引力の 1 Z 3強でよいこととなる。 磁石保持部材 3 3 0の傾動に要する力は、 磁石保持部材 3 3 0全体をピン支持台 2 5 4に対し て直角に離間させる場合に要する力 (磁気吸引力の合力に等しい) に比較し て小さくて済むのであり、 ピン部材 2 7 4が更に上昇させられることにより 係合部 3 1 2が突部 3 3 8に係合し、 永久磁石部 3 3 4全体がピン支持台 2 5 4から離間させられれば、 磁気吸引力が消滅させられる。 永久磁石部 3 3 4がピン支持台 2 5 4に最も接近して基台 2 7 2に磁気吸引力を加える状態 において、 係合面 3 4 0は係合面 3 4 2より下側に位置し、 係合面 3 4 0の 方が係合面 3 4 2より係合部 3 1 0に近く、 初めに係合し、 次に係合面 3 4 2が係合部 3 1 2に係合し、 係合部 3 1 0, 3 1 2と突部 3 3 6, 3 3 8と が、 ピン部材 2 7 4の軸方向において互いに異なる 2つの位置において、 時 期をずらして係合し、 永久磁石部 3 3 4を傾動させる。 ピン部材 2 7 4が更 に上昇させられれば、 図 2 1 (b)に示すように C形部材 3 0 4が基台 2 7 2の 天壁 3 1 4に係合し、 基台 2 7 2がピン支持台 2 5 4から持ち上げられ、 支 持ピン 2 5 0全体がピン支持台 2 5 4から簡単に持ち上げられる。 The support pin gripping device 2 52 is further raised from this state, but the advancing / retreating member 3 64 is raised together with the gripping device body 360, and the gripping claw group 36 2 and the support pin 250 are raised. Let me do. The gripping claws 3 94, 3 96 are configured such that the claws 4 10, 4 12 engage with the annular engaging portion 3 29 to apply a tensile force to the pin member 2 7 4, and the base 2 7 2 To raise against. During the ascent, first, the engaging portion 310 of the C-shaped member 304 engages with the protrusion 336. Therefore, as shown in FIG. 21 (a), the magnet holding member 330 is formed around the contact portion between the protrusion 338 side of the bottom surface 335 and the bottom plate 292, The magnetic attraction force is reduced by being piled up and inclined at the attraction force, and being obliquely separated from the pin support 254. The tensile force applied to the pin member 274 is transmitted to the permanent magnet portion 334 as a force for tilting the permanent magnet portion 334. At this time, the combined force of the magnetic attraction force, which can be considered to act intensively at the center of the permanent magnet part 3 34, the force applied by the engaging part 3 10 to the protrusion 3 36, and the bottom plate 2 9 2 can be countered by the force applied to the protrusion 3 3 8 side of the bottom surface 3 3 5 of the magnet holding member 3 3 0.Moreover, from the resultant force of the magnetic attractive force, the engaging portion 3 10 The horizontal distance (the distance in the direction parallel to the bottom plate 292) to the point of contact with the protrusion 338 is from the point of contact between the protrusion 338 side of the bottom surface 335 and the bottom plate 292. Since the horizontal distance is slightly less than twice the horizontal distance, the force that the engaging portion 310 should apply to the protrusion 336 may be a little more than 1 Z3 of the magnetic attraction force. The force required to tilt the magnet holding member 330 is compared to the force required to separate the entire magnet holding member 330 at right angles to the pin support 254 (equivalent to the resultant force of the magnetic attraction force). When the pin member 27 is further raised, the engaging portion 312 engages with the projection 338, and the entire permanent magnet portion 334 is pin-supported. If it is separated from, the magnetic attraction will disappear. When the permanent magnet section 3 3 4 is closest to the pin support 2 5 4 and applies magnetic attraction to the base 2 7 2, the engaging surface 3 4 0 is located below the engaging surface 3 4 2. The engaging surface 340 is closer to the engaging portion 310 than the engaging surface 342, and is engaged first, and then the engaging surface 342 is engaged with the engaging portion 314. And the engaging portions 310, 312 and the protrusions 336, 338 However, at the two positions different from each other in the axial direction of the pin member 274, they are engaged at different times to tilt the permanent magnet portion 334. When the pin member 274 is further raised, the C-shaped member 304 engages with the top wall 314 of the base 272 as shown in FIG. 2 is lifted from the pin support 25 4 and the entire support pin 250 is easily lifted from the pin support 2 54.
[0065] 互いに対称に開閉する把持爪 3 9 4, 3 9 6は、 嵌合穴 3 8 2に嵌合され た支持ピン 2 5 0に接触して把持するが、 それらは軸対称に開閉させられる とともに、 把持面 4 1 3 , 4 1 4の長さ、 すなわち支持ピン 2 5 0を把持し た際にその軸線に沿った状態となる方向の長さが短く、 支持ピン 2 5 0の相 対的な傾きを許容する状態で係合し、 嵌合穴 3 8 6による支持ピン 2 5 0の 心出しを妨げることはなく、 支持ピン 2 5 0はその軸線が鉛直となる姿勢で 搬送される。 [0065] The gripping claws 394, 3966, which open and close symmetrically with each other, contact and grip the support pins 250 fitted in the fitting holes 382, but they are opened and closed axially symmetrically. And the length of the gripping surfaces 4 13 and 4 14, that is, the length in the direction along the axis when gripping the support pin 250 is short, and the phase of the support pin 250 is small. It engages in a state that allows a counter tilt, does not prevent the centering of the support pin 250 by the fitting hole 386, and the support pin 250 is transported in a posture where the axis is vertical You.
[0066] 支持ピン把持装置 2 5 2は、 上昇端位置へ移動させられるとともに、 へッ ド移動装置 4 2により可動レール 2 1 2あるいは 2 1 6を越えて支持ピン収 納装置 2 5 6へ移動させられ、 支持ピン 2 5 0を図 2 1 (b)に示す状態で搬送 する。 支持ピン把持装置 2 5 2は支持ピン収納装置 2 5 6の複数のピン収納 穴 6 0 2のうち、 空いているピン収納穴 6 0 2の上方へ移動させられた後、 下降させられて支持ピン 2 5 0を収納する。 なお、 支持ピン収納装置 2 5 6 に対する支持ピン 2 5 0の収納, 取出しに先立って基準マーク 6 1 0, 6 1 2がマーク撮像装置 1 6 4により撮像され、 ピン収納穴 6 0 2に収納された 支持ピン 2 5 0の基板搬送装置 2 4の幅方向の位置が検出されている。  The support pin gripping device 25 2 is moved to the rising end position, and crosses the movable rail 21 2 or 21 6 by the head moving device 42 to the support pin storage device 25 6. It is moved and the support pins 250 are transported in the state shown in FIG. 21 (b). The support pin gripping device 25 2 is moved above the empty pin storage hole 62 out of the plurality of pin storage holes 62 of the support pin storage device 256, and then lowered and supported. Holds pin 250. Prior to the storage and removal of the support pin 250 from the support pin storage device 256, the reference marks 610 and 612 are imaged by the mark imaging device 164 and stored in the pin storage hole 602. The position of the support pin 250 in the width direction of the substrate transfer device 24 is detected.
[0067] 支持ピン収納装置 2 5 6は可動レール 2 1 2, 2 1 6と共に移動し、 可動 レール 2 1 2, 2 1 6の移動に伴って、 基板搬送装置 2 4の幅方向における 位置が変化し、 収納された支持ピン 2 5 0の位置が変化する。 そのため、 支 持ピン 2 5 0の位置は、 可動レール 2 1 2, 2 1 6が移動させられて搬送幅 が変更され、 支持ピン収納装置 2 5 6の位置が変わったとき検出される。 可 動レール 2 1 2, 2 1 6の Y軸方向の位置は、 基板 5 0の種類に応じて予め 設定されており、 マーク撮像時には、 可動レール 2 1 2 , 2 1 6の位置に基 づいて、 基準マーク 61 0, 61 2が位置することが予定されている位置へ マーク撮像装置 1 64が移動させられて基準マーク 61 0, 61 2を真上か ら、 すなわち基準マーク 61 0, 61 2と対向する位置から撮像する。 マー ク撮像装置 1 64は第二 X軸スライド 98に搭載されており、 ヘッド移動装 置 42により移動させられる。 [0067] The support pin storage device 25 6 moves together with the movable rails 2 12 and 2 16, and with the movement of the movable rails 2 12 and 2 16, the position of the substrate transfer device 24 in the width direction is changed. The position of the stored support pin 250 changes. Therefore, the position of the support pin 250 is detected when the movable rails 212 and 216 are moved to change the conveyance width, and the position of the support pin storage device 256 is changed. The positions of the movable rails 2 1 2 and 2 16 in the Y-axis direction are set in advance according to the type of the substrate 50, and at the time of mark imaging, are based on the positions of the movable rails 2 1 2 and 2 16. Then, the mark image pickup device 164 is moved to a position where the reference marks 61 0 and 612 are expected to be located, and the reference marks 61 0 and 612 are directly above, that is, the reference marks 610 and 612. Take an image from the position facing 612. The mark imaging device 164 is mounted on the second X-axis slide 98 and is moved by the head moving device.
[0068] そして、 マーク撮像装置 1 64の位置と、 その位置において撮像された画 像内における基準マーク 61 0, 61 2の位置とに基づいて、 基準マーク 6 1 0, 61 2の実際の位置が取得され、 それら位置と、 支持ピン収納装置 2Then, based on the position of the mark imaging device 164 and the positions of the reference marks 610 and 612 in the image captured at that position, the actual positions of the reference marks 610 and 612 are determined. And their positions and the support pin storage device 2
56の複数のピン収納穴 602と基準マーク 61 0, 61 2との相対位置情 報とに基づいて、 ピン収納穴 602の各中心位置が演算され、 支持ピン 25 0の各位置が取得される。 本実施例では、 支持ピン 250はピン収納穴 60 2に嵌合されて同心に位置決めされるようにされており、 ピン収納穴 602 の位置の検出により支持ピン 250の位置が検出される。 これら位置は、 複 数のピン収納穴 602の各々を特定するデータと対応付けてコンピュータ 6Based on the relative position information between the 56 pin storage holes 602 and the reference marks 610, 612, the respective center positions of the pin storage holes 602 are calculated, and the respective positions of the support pins 250 are obtained. . In the present embodiment, the support pins 250 are fitted in the pin storage holes 602 and are positioned concentrically, and the position of the support pins 250 is detected by detecting the position of the pin storage holes 602. These positions are associated with data identifying each of the plurality of pin storage holes 602, and

In the present embodiment, the mark imaging device 1 64 also serves as the imaging device for the reference marks 610 and 612 that are the imaging target portions of the support pin storage device 256, and the head moving device 42 also serves as the imaging device moving device. A support pin position detecting device is constituted together with a position calculating device constituted by a portion for detecting the position of the supporting pin of the device 650. When the support pin 250 is returned to the pin storage hole 602, the position stored in association with the pin storage hole 602 is read out, and the support pin gripping device 252 is accurately moved onto the pin storage hole 602. The support pin 250 is accurately stored in the pin storage hole 602.
[0069] 支持ピン把持装置 252の下降により、 基台 272が案内面 606により 案内されつつピン収納穴 602に嵌合されて位置決めされるとともに、 底面 608に到達して着座させられる。 支持ピン把持装置 252の更なる下降に より、 ピン部材 274が基台 272に対して下降し、 磁石保持部材 330の 底面 335全体が底板 292に当接させられるとともに、 ピン収納穴 602 の磁性材料製の底面 608により磁気的に吸引され、 その磁気吸引力に基づ いて基台 2 7 2を底面 6 0 8に押し付け、 固定する。 底面 6 0 8および永久 磁石部 3 3 4が支持ピン固定装置を構成し、 支持ピン 2 5 0はピン収納穴 6 0 2に位置決めされた状態で固定される。 支持ピン把持装置 2 5 2は、 この 状態から更に下降させられるが、 進退部材 3 6 4は、 ピン収納穴 6 0 2に固 定された支持ピン 2 5 0により下降を阻止され、 把持装置本体 3 6 0がスプ リング 3 7 4を圧縮しつつ進退部材 3 6 4に対して下降する。 進退部材 3 6 4が支持ピン 2 5 0の先端部により押され、 把持装置本体 3 6 0に対して相 対的に上昇させられて非作用位置から作用位置に向かう向きに移動させられ 、 後退端位置へ移動させられるのである。 When the support pin gripping device 252 is lowered, the base 272 is fitted and positioned in the pin storage hole 602 while being guided by the guide surface 606, and reaches the bottom surface 608 to be seated.

The bottom surface 608 and the permanent magnet portion 334 constitute a support pin fixing device, and the support pin 250 is fixed while being positioned in the pin storage hole 602. The support pin gripping device 255 is further lowered from this state, but the reciprocating member 365 is prevented from lowering by the support pin 250 fixed to the pin storage hole 62, and the gripping device main body is moved. The 360 moves down with respect to the advance / retreat member 365 while compressing the spring 37 4. The advancing / retreating member 365 is pushed by the tip of the support pin 250, is relatively raised with respect to the gripping device body 360, is moved from the non-working position toward the working position, and is retracted. It is moved to the end position.
それにより、 係止装置 4 3 2においては、 図 2 3 (a)に示す状態から、 図 2 3 (b)に示すように、 回動係止部材 4 7 2の係合部 4 8 2, 4 8 4が被係止面 5 1 0, 5 3 0から離間させられ、 係止が解除される。 この際、 回動係止部 材 4 7 2は鉛直の姿勢を保って案内部 4 9 0, 4 9 2に対して相対的に下降 する。 やがて、 図 2 3 (b)に示すように、 係合部 4 8 4が第七案内面 5 1 8に 係合し、 それ以後は図において左方へ移動させられるのに対し、 係合部 4 8 2の右方への移動は第三案内面 5 0 4により阻止されるため、 回動係止部材 4 7 2が逆方向にねじられる。 係合部 4 8 4は、 第七案内面 5 1 8の案内に より、 図 2 3 (b)に二点鎖線の円のみで示す位置より左方に位置させられるの である。 係合部 4 8 4が第四案内溝部 5 2 7に嵌入した後、 図 2 3 (C)に示す ように、 係合部 4 8 2全体が第三案内面 5 0 4から外れ、 回動係止部材 4 7 2の弾性復元力により図において右方へ移動させられ、 第一案内溝部 5 1 2 の真下へ移動する。 したがって、 支持ピン把持装置 2 5 2が下降端位置へ下 降させられた後、 上昇を開始すれば、 係合部 4 8 2が第一案内溝部 5 1 2に 嵌入する。 支持ピン把持装置 2 5 2が上昇させられるときには、 係合部 4 8 2, 4 8 4と被係止面 5 1 0, 5 3 0との係止が解除されるとともに、 進退 部材 3 6 4はスプリング 3 7 4の付勢により支持ピン 2 5 0に押し付けられ ており、 把持装置本体 3 6 0のみが上昇させられる。 換言すれば、 回動係止 部材 4 7 2が被係止部材 4 7 0に対して相対的に上昇するのであり、 第一, 第五案内溝部 5 1 2 , 5 2 8および第五案内面 5 0 8に案内される図 2 3 (d) に示す状態を経て、 図 2 3 (e)に示す原位置へ復帰する。 As a result, in the locking device 43, from the state shown in FIG. 23 (a), as shown in FIG. 23 (b), the engaging portions 482, 484 is separated from the locked surfaces 5110 and 5330, and the lock is released. At this time, the rotation locking member 472 descends relatively to the guide portions 490, 492 while maintaining the vertical posture. Eventually, as shown in FIG. 23 (b), the engaging portion 484 is engaged with the seventh guide surface 518, and thereafter moved to the left in the figure, The rightward movement of 482 is prevented by the third guide surface 504, so that the rotation locking member 472 is twisted in the opposite direction. The engagement portion 484 is positioned leftward from the position indicated by only the two-dot chain line circle in FIG. 23 (b) by the guide of the seventh guide surface 518. After the engagement portion 484 is fitted into the fourth guide groove portion 527, as shown in FIG. 23 (C), the entire engagement portion 482 is disengaged from the third guide surface 504, and is rotated. It is moved rightward in the figure by the elastic restoring force of the locking member 472, and moves right below the first guide groove portion 512. Therefore, if the support pin gripping device 25 2 is moved down after being lowered to the lower end position, the engaging portion 48 2 is fitted into the first guide groove portion 5 12. When the support pin gripping device 25 is raised, the engagement between the engaging portions 482, 484 and the locked surfaces 510, 530 is released, and the advancing / retracting member 364 is provided. Is pressed against the support pin 250 by the bias of the spring 374, and only the gripping device main body 360 is raised. In other words, the rotation locking member 472 rises relatively with respect to the locked member 470. The state returns to the original position shown in FIG. 23 (e) through the state shown in FIG. 23 (d) guided by the fifth guide groove portions 512, 528 and the fifth guide surface 508.
[0071 ] 係合部 4 8 2が第一案内溝部 5 1 2および第五案内面 5 0 8により案内さ れ、 係合部 4 8 4が第五案内溝部 5 2 8により案内されるとき、 アーム部 4 7 8, 4 8 0は互いに逆向きにねじられる。 ねじりがない場合の係合部 4 8 2, 4 8 4の位置を図 2 3 (d)に二点鎖線の円で示すように、 第一, 第五案内 溝部 5 1 2, 5 2 8および第五案内面 5 0 8により案内されない場合より、 係合部 4 8 2は回動角度が大きく、 係合部 4 8 4は回動角度が小さく、 ァー ム部 4 7 8, 4 8 0が互いに逆向きにねじられるのである。 そして、 係合部 4 8 2は第五案内面 5 0 8から外れれば、 回動係止部材 4 7 2の弾性復元力 により、 回動係止部材 4 7 2の回動軸線側へ回動させられ、 係合部 4 8 4も 第二案内溝部 5 2 4に進入する位置へ回動させられ、 回動係止部材 4 7 2が 原位置へ復帰する。 [0071] When the engaging portion 482 is guided by the first guide groove portion 512 and the fifth guide surface 508, and the engaging portion 484 is guided by the fifth guide groove portion 528, The arms 478 and 480 are twisted in opposite directions. As shown by the two-dot chain line in FIG. 23 (d), the positions of the engaging portions 482, 484 when there is no torsion are indicated by the first and fifth guide grooves 51, 52, 58 and The engaging portion 482 has a larger turning angle, the engaging portion 484 has a smaller turning angle, and the arm portions 478, 480 than when not guided by the fifth guide surface 508. Are twisted in opposite directions. Then, when the engagement portion 482 is disengaged from the fifth guide surface 508, the engagement portion 482 is rotated toward the rotation axis of the rotation locking member 472 by the elastic restoring force of the rotation locking member 472. As a result, the engaging portion 484 is also rotated to a position where it enters the second guide groove portion 524, and the rotation locking member 472 returns to the original position.
[0072] 回動係止部材 4 7 2の原位置への移動と並行して進退部材 3 6 4が把持装 置本体 3 6 0に対して相対的に下降して非作用位置へ移動し、 図 1 6に示す ように把持爪群保持部 3 7 0が把持装置本体 3 6 0から離脱させられ、 把持 爪 3 9 4, 3 9 6がスプリング 4 1 8, 4 2 0の付勢により開方向へ回動さ せられ、 支持ピン 2 5 0を開放する。 そのため支持ピン把持装置 2 5 2は、 回動係止部材 4 7 2が原位置に到達し、 進退部材 3 6 4が非作用位置へ復帰 した後、 更に上昇させられるが、 その際、 突部 3 7 8と凹部 3 7 6の端面と の係合により進退部材 3 6 4が把持装置本体 3 6 0と共に上昇させられ、 支 持ピン 2 5 0が嵌合穴 3 8 6から抜け出させられ、 支持ピン収納装置 2 5 6 に収納された状態に保たれる。  In parallel with the movement of the rotation locking member 4 72 to the original position, the advancing / retreating member 365 descends relatively to the gripping device main body 360 and moves to the non-operating position, As shown in Fig. 16, the gripper claw group holder 370 is disengaged from the gripper body 360, and the grippers 394, 396 are opened by the bias of the springs 418, 420. The support pin 250 is opened. Therefore, the support pin gripping device 255 is further raised after the rotation locking member 472 has reached the original position and the reciprocating member 364 has returned to the non-operating position. By the engagement of the 378 with the end face of the concave portion 376, the reciprocating member 364 is raised together with the gripping device main body 360, and the support pin 250 is disengaged from the fitting hole 386. It is kept in the state of being stored in the support pin storage device 256.
[0073] このように被係止部材 4 7 0は一対の案内部 4 9 0, 4 9 2を有している が、 これら案内部 4 9 0, 4 9 2は、 進退部材 3 6 4と把持装置本体 3 7 0 との軸方向の相対移動に伴って、 原則として係合部 4 8 2, 4 8 4の少なく とも一方を拘束し、 回動係止部材 4 7 2が自由に回動する状態になることが ないように設けられている。 一方の係合部が自由な状態になる場合、 それに 先立って他方の係合部が案内溝部によリ拘束されて、 一方の係合部の移動方 向が決まるようにされ、 両方の係合部が共に案内溝部内に位置するようにさ れ、 係合部 4 8 2, 4 8 4が、 回動係止部材 4 7 2の回動方向において互い に逆の方向から案内面に係合して、 移動方向が決まるようにされているので ある。 このように一対の案内部 4 9 0, 4 9 2が互いに共同することにより 、 進退部材 3 6 4の 2回の進退に伴って、 係合部 4 8 2, 4 8 4が被係止部 を含んで予め設定された周回運動を行わされるのであり、 逆の作動である被 係止面 5 1 0, 5 3 0との係合と、 その係合の解除とが容易に行われ、 進退 部材 3 6 4が 2回、 非作用位置から作用位置に向かって押されることにより 、 支持ピン 2 5 0の把持, 把持状態の維持および開放が容易に行われる。 [0073] As described above, the locked member 470 has a pair of guide portions 490, 492, and these guide portions 490, 492 are formed by the reciprocating member 364, As a result of the relative movement in the axial direction with the gripping device main body 370, at least one of the engaging portions 482, 484 is restrained in principle, and the rotation locking member 472 freely rotates. It is provided so that it will not be in a state where If one of the engagement parts is free, Prior to this, the other engaging portion is restrained by the guide groove so that the moving direction of one of the engaging portions is determined, and both of the engaging portions are located in the guide groove. The engaging portions 482, 484 are engaged with the guide surfaces from opposite directions in the rotating direction of the rotation locking member 472, so that the moving direction is determined. . As described above, the pair of guide portions 490 and 492 cooperate with each other, so that the engaging portions 482 and 484 are locked by the forward and backward movement of the advance / retreat member 364 twice. A predetermined orbiting motion is performed including the following, and the engagement with the locked surfaces 5110 and 5330, which are the opposite operations, and the release of the engagement are easily performed. By pressing the reciprocating member 365 twice from the non-operating position toward the operating position, the holding of the support pin 250, the maintenance of the holding state, and the release are facilitated.
[0074] また、 支持ピン把持装置 2 5 2が把持した支持ピン 2 5 0をピン支持台 2 5 4や支持ピン収納装置 2 5 6に置いたり、 収納するためには、 それらに対 する接近, 離間動作が必要である。 支持ピン把持装置 2 5 2においては、 こ の動作を利用して進退部材 3 6 4を進退させて把持爪群 3 6 2を開閉させる ため、 把持爪群開閉のために新たにァクチユエータを追加することなく、 支 持ピン 2 5 0を把持, 開放することができる。  Further, in order to place or store the support pins 250 held by the support pin gripping device 25 2 on the pin support base 255 4 or the support pin storage device 256, it is necessary to approach the support pins 250. , Separation operation is required. In the support pin gripping device 2 52, a new actuator is added to open and close the gripping claw group 362 by using this operation to advance and retreat the advancing / retreating member 364 to open and close the gripping claw group 362. The support pin 250 can be gripped and released without any need.
[0075] なお、 支持ピン 2 5 0を開放した把持爪群 3 6 2は常には開状態に切リ換 えられており、 把持爪 3 9 4の突部 4 1 5は作用レバー 4 4 0のローラ 4 6 0の下方に位置し、 ローラ 4 6 0を覆っている。 そのため、 ノズル保持へッ ド 4 0が部品供給装置 2 2から回路部品を取り出した後、 部品撮像装置 1 1 0により下方から撮像されるとき、 ローラ 4 6 0が光つて回路部品の画像形 成に悪影響を及ぼすことが回避される。  [0075] The gripping claw group 362 with the support pin 250 released is always switched to the open state, and the protrusion 415 of the gripping claw 394 is actuated by the operating lever 440. The roller is located below the roller 460 and covers the roller 460. Therefore, when the nozzle holding head 40 takes out the circuit component from the component supply device 22 and then the component imaging device 110 captures an image from below, the roller 460 is illuminated to form an image of the circuit component. Adverse effects are avoided.
[0076] 以上、 支持ピン 2 5 0をピン支持台 2 5 4から取り外して支持ピン収納装 置 2 5 6に収納する場合を説明したが、 支持ピン収納装置 2 5 6から支持ピ ン 2 5 0を取り出してピン支持台 2 5 4に取リ付ける場合、 ピン支持台 2 5 4上において支持ピン 2 5 0の位置を変える場合にも同様に、 進退部材 3 6 4が 2回、 作動させられて支持ピン 2 5 0の把持, 搬送および載置後の開放 が行われる。 [0077] 支持ピン位置検出装置の別の実施例を図 2 5に基づいて説明する。 本実施 例の支持ピン位置検出装置は、 可動レールを移動させるレール移動装置 7 0 0のエンコーダ 7 0 2と位置演算装置 7 0 4とを含む。 レール移動装置 7 0 0は、 例えば、 前記レール移動装置 2 2 6と同様に構成され、 レール位置変 更モータ 7 0 6について設けられたエンコーダ 7 0 2の出力は、 可動レール の位置に対応する信号を出力し、 制御装置 7 0 8に入力される。 制御装置 7 0 8は前記制御装置 6 5 0と同様にコンピュータを主体として構成され、 そ の位置演算装置 7 0 4を構成する部分においては、 エンコーダ 7 0 2の出力 と、 予め設定されている可動レールとピン収納穴との相対位置の情報とに基 づいて支持ピンの位置を演算する。 この情報は、 例えば可動レール上に設定 された基準位置ないしレール位置取得位置箇所と複数のピン収納穴の各中心 位置との X軸, Y軸方向における相対位置情報を含む。 The case where the support pins 250 are detached from the pin support pedestal 25 4 and stored in the support pin storage device 256 has been described above. When removing 0 and attaching it to the pin support 25 4, also when changing the position of the support pin 2 50 on the pin support 2 5 4, the reciprocating member 3 64 is operated twice as well. Then, the support pins 250 are gripped, transported, and released after being placed. Another embodiment of the support pin position detecting device will be described with reference to FIG. The support pin position detecting device of the present embodiment includes an encoder 720 of a rail moving device 700 for moving a movable rail and a position calculating device 704. The rail moving device 700 has, for example, the same configuration as that of the rail moving device 222, and the output of the encoder 720 provided for the rail position changing motor 706 corresponds to the position of the movable rail. A signal is output and input to the control device 708. The control device 7 08 is constituted mainly by a computer similarly to the control device 6 50, and in the portion constituting the position calculation device 7 04, the output of the encoder 7 0 2 is set in advance. The position of the support pin is calculated based on information on the relative position between the movable rail and the pin storage hole. This information includes, for example, relative position information in the X-axis and Y-axis directions between the reference position or the rail position acquisition position set on the movable rail and the center position of each of the plurality of pin storage holes.
[0078] 作動部材が係合する係合部材は、 支持ピン以外の部材により構成してもよ い。 例えば、 図 2 6に示す支持ピン把持装置 7 2 0においては、 進退部材 7 2 2から突部 7 2 4が、 その進退方向と交差する方向、 本実施例においては 直角に延び出させられ、 係合部を構成するとともに、 保持体 7 2 8に、 突部 7 2 4と対向する上向きの係合面 7 3 0を備えた係合部材 7 3 2が設けられ ている。 係合面 7 3 0は、 支持ピン把持装置 7 2 0が昇降装置により下降さ せられ、 把持爪群 3 6 2がちょうど支持ピン 2 5 0を把持する位置に至った ときに突部 7 2 4が係合する位置に設けられている。 なお、 支持ピン 2 5 0 が嵌合される嵌合穴 7 3 6は、 底面 7 3 8が支持ピン 2 5 0が当たらない深 さを有するものとされている。 支持ピン把持装置 7 2 0が下降させられ、 支 持ピン 2 5 0の先端部が嵌合穴 7 3 6に嵌合されて、 把持爪群 3 6 2が閉状 態への切換えにより被把持部 3 2 8を把持する位置に至ったとき、 突部 7 2 4と係合面 7 3 0との係合により進退部材 7 2 2の下降が止められ、 その後 の把持装置本体 3 6 0の下降時に進退部材 7 2 2が係合部材 7 3 2により押 され、 非作用位置から作用位置に向かう方向へ移動させられる。 それにより 把持爪群 3 6 2が閉じられて支持ピン 2 5 0を把持する。 係合部材 7 3 2が 進退部材 7 2 2に係合して、 非作用位置から作用位置へ向かう向きに押すこ と以外、 支持ピン 2 5 0が進退部材に係合して作動させる場合と同様に支持 ピン 2 5 0の把持, 開放が行われる。 [0078] The engagement member with which the operating member engages may be configured by a member other than the support pin. For example, in the support pin gripping device 720 shown in FIG. 26, the projecting portion 724 from the reciprocating member 72 is extended in a direction intersecting the retreating direction, in this embodiment, at right angles, In addition to forming the engaging portion, the holding member 728 is provided with an engaging member 732 having an upward engaging surface 730 facing the projection 724. When the support pin gripping device 720 is lowered by the elevating device, the engaging surface 730 is projected when the gripping claw group 362 just reaches the position where the support pin 250 is gripped. 4 are provided at positions where they engage. Note that the fitting hole 736 into which the support pin 250 is fitted has a depth such that the bottom surface 738 does not touch the support pin 250. The support pin gripping device 720 is lowered, the tip of the support pin 250 is fitted into the fitting hole 736, and the gripping claw group 362 is switched to the closed state to be gripped. When the position for gripping the 328 is reached, the lowering of the advancing / retreating member 722 is stopped by the engagement of the projection 724 with the engagement surface 730, and the lowering of the gripping device body 360 thereafter. At this time, the reciprocating member 722 is pushed by the engaging member 7332, and is moved in the direction from the non-operating position to the operating position. As a result, the group of gripping claws 36 2 is closed to grip the support pin 250. Engaging member 7 3 2 Except for engaging with the reciprocating member 7 22 and pushing in the direction from the non-operating position to the operating position, the supporting pin 250 is similar to the case where the supporting pin 250 is engaged with the reciprocating member and operated. Is gripped and released.
[0079] ピン支持部材および支持ピン収納装置を係合部材として利用してもよい。 [0079] A pin support member and a support pin storage device may be used as an engagement member.
例えば、 図 2 7に示す支持ピン把持装置 7 4 0のように、 進退部材 7 4 2か ら下方へ、 ピン支持台 2 5 4に向かって係合アーム 7 4 4を延び出させて係 合部を設ける。 係合アーム 7 4 4は、 把持爪群 3 6 2がちょうど支持ピン 2 5 0を把持する位置に至ったときにピン支持面 2 7 6に当接するように設け られており、 係合アーム 7 4 4とピン支持面 2 7 6との係合によリ進退部材 For example, as shown in a support pin gripping device 7400 shown in FIG. 27, the engagement arm 7444 is extended downward from the reciprocating member 7424 toward the pin support 254 to engage. Part is provided. The engagement arm 7 4 4 is provided so as to come into contact with the pin support surface 2 76 when the gripping claw group 3 6 2 has just reached the position where the support pin 2 50 is gripped. 4 4 and pin support surface 2 7 6
7 4 2の下降が止められ、 把持装置本体 3 6 0に対して押し上げられること となる。 また、 図示は省略するが、 支持ピンの支持ピン収納装置への収納時 には、 係合アーム 7 4 4が支持ピン収納装置の構成要素、 例えば、 収納体に 係合して進退部材 7 4 2の下降が止められるようにされる。 The lowering of the 742 is stopped, and it is pushed up against the gripper body 360. Also, although not shown, when the support pins are stored in the support pin storage device, the engaging arm 744 is engaged with a component of the support pin storage device, for example, the retractable member 74 by engaging with the storage body. The descent of 2 is stopped.
[0080] 支持ピンの力伝達装置は、 永久磁石に回転モーメントを生じさせる装置と してもよい。 例えば、 図 2 8に示す支持ピン 7 7 0の永久磁石部 7 7 2は、 永久磁石 7 7 4および磁石保持部材 7 7 6を含み、 基台 7 7 8の内側空間 7 [0080] The force transmission device of the support pin may be a device that generates a rotational moment in the permanent magnet. For example, the permanent magnet portion 772 of the support pin 770 shown in FIG. 28 includes a permanent magnet 774 and a magnet holding member 776, and an inner space 7 of the base 778.
8 0内に配設されるとともに、 磁石保持部材 7 7 6が、 内側空間 7 8 0を構 成する溝 7 8 2の長手方向に平行な方向において、 永久磁石 7 7 4から外れ た部分において軸 7 8 4により基台 7 7 8に回動可能に取り付けられている 。 磁石保持部材 7 7 6の自由端部には突部 7 9 0が突設されて第二係合部を 構成している。 ピン部材 7 9 4の基端部は内側空間 7 8 0内に位置させられ るとともに、 突部 7 9 0に下方から係合可能な係合部 7 9 6が設けられ、 第 一係合部を構成している。 The magnet holding member 776 is disposed in the inside of the groove 78, and the magnet holding member 776 is separated from the permanent magnet 774 in a direction parallel to the longitudinal direction of the groove 782 constituting the inner space 7800. It is rotatably attached to the base 7778 by a shaft 784. A projection 790 projects from a free end of the magnet holding member 776 to constitute a second engagement portion. The base end of the pin member 794 is located in the inner space 780, and the projection 790 is provided with an engagement portion 796 that can be engaged from below, and the first engagement portion Is composed.
[0081 ] ピン部材 7 9 4に引張力が加えられれば、 係合部 7 9 6が突部 7 9 0に係 合し、 磁石保持部材 7 7 6を回動させ、 永久磁石部 7 7 2を傾斜させつつピ ン支持台 2 5 4から離間させる。 突部 7 9 0は永久磁石 7 7 4から外れた位 置に設けられており、 永久磁石部 7 7 2とピン支持台 2 5 4との間に作用す る磁気吸引力の合力の作用線から外れた位置において突部 7 9 0と係合部 7 9 6とが互いに係合し、 永久磁石部 7 7 2に回転モーメントを生じさせ、 回 動させるのである。 この場合、 係合部 7 9 6が突部 7 9 0に加える力と、 軸 7 8 4が磁石保持部材 7 7 6に加える力とが、 磁気吸引力の合力に対抗し、 永久磁石部 7 7 2は小さい引張力で傾動させられ、 磁気吸引力が減少させら れる。 [0081] When a tensile force is applied to the pin member 794, the engaging portion 796 engages with the protruding portion 790, and the magnet holding member 770 is rotated, so that the permanent magnet portion 770 While tilting it away from the pin support 2 54. The protrusion 790 is provided at a position deviated from the permanent magnet 774, and is a line of action of the resultant force of the magnetic attraction acting between the permanent magnet 770 and the pin support 254. The protrusion 7 9 0 and the engagement 7 9 and 6 engage with each other to generate a rotational moment in the permanent magnet section 772 and rotate it. In this case, the force applied by the engaging portion 796 to the protrusion 790 and the force applied by the shaft 784 to the magnet holding member 770 oppose the resultant force of the magnetic attraction, and the permanent magnet portion 7 72 is tilted with a small pulling force, and the magnetic attraction force is reduced.
[0082] なお、 支持ピンの C形部材は軟鉄等の磁性材料製としてもよい。 C形部材 を非磁性材料製とすれば、 C形部材に磁気吸引力が作用せず、 磁石保持部材 をピン支持台に対して傾け易い。 しかし、 C形部材を磁性材料製としても、 ピン支持台の磁気吸引力が及ばないのであれば、 磁石保持部材に係合して傾 動させることができる。 磁石保持部材は、 基台の底板から離間させられた状 態では、 C形部材により磁力により本体部に吸引され、 真っ直ぐな状態で保 持され得る。  [0082] The C-shaped member of the support pin may be made of a magnetic material such as soft iron. If the C-shaped member is made of a non-magnetic material, magnetic attraction does not act on the C-shaped member, and the magnet holding member is easily inclined with respect to the pin support. However, even if the C-shaped member is made of a magnetic material, it can be engaged with the magnet holding member and tilted as long as the magnetic attraction of the pin support does not reach. In a state where the magnet holding member is separated from the bottom plate of the base, the magnet holding member is attracted to the main body by the magnetic force by the C-shaped member, and can be held in a straight state.
