Description
本発明は、ＩＣチップ等の部品を基板上に実装する表面実装機において、実装する部品を保持する部品保持ヘッドに関する。 The present invention relates to a component holding head for holding a component to be mounted in a surface mounter that mounts a component such as an IC chip on a substrate.
表面実装機は、ノズル等の保持具を有する部品保持ヘッドにより、部品を部品供給部からピックアップし保持してプリント基板上に移送し、プリント基板上の所定位置に実装するように構成されている。 The surface mounter is configured to pick up and hold a component from a component supply unit, transfer it onto a printed circuit board, and mount it at a predetermined position on the printed circuit board by a component holding head having a holder such as a nozzle. .
かかる部品保持ヘッドとしては、そのヘッド本体に、複数の保持具を有するロータリーヘッドが垂直軸周りに回転可能に取り付けられた、ロータリー式の部品保持ヘッドが知られている（例えば特許文献１）。 As such a component holding head, there is known a rotary type component holding head in which a rotary head having a plurality of holders is attached to the head body so as to be rotatable around a vertical axis (for example, Patent Document 1).
ロータリー式の部品保持ヘッドにおいては、ロータリーヘッドに搭載されたセンサや保持具のアクチュエータ等を駆動させるために、ヘッド本体からロータリーヘッドに電力を供給する必要がある。その電力供給機構としては、上記特許文献１にも見られるように、一般的にスリップリング機構が用いられている。しかし、スリップリング機構では、スリップリングとブラシとの回転接触を伴うため、耐久性やユニット小型化等に問題があった。 In the rotary type component holding head, it is necessary to supply electric power from the head body to the rotary head in order to drive a sensor mounted on the rotary head, an actuator of a holding tool, or the like. As the power supply mechanism, a slip ring mechanism is generally used as can be seen in Patent Document 1 described above. However, since the slip ring mechanism involves rotational contact between the slip ring and the brush, there are problems in durability, unit miniaturization, and the like.
これに対して特許文献２では、非接触式のエネルギ・データ伝達手段を備えたロータリー式の部品保持ヘッドが提案されている（段落００３４〜段落００３６及び図１参照）。 On the other hand, Patent Document 2 proposes a rotary type component holding head provided with a non-contact type energy data transmission means (see paragraphs 0034 to 0036 and FIG. 1).
図６は、特許文献２のエネルギ・データ伝達手段の要部を再現したものである。このエネルギ・データ伝達手段は、エネルギ（電力）伝達のために環状の第１コア１００及び第２コア２００を備え、データ（信号）伝達のためにプレート状の第１アンテナ３００及び第２アンテナ４００を備える。 FIG. 6 is a reproduction of the main part of the energy / data transmission means of Patent Document 2. The energy / data transmission means includes an annular first core 100 and a second core 200 for energy (power) transmission, and plate-shaped first antenna 300 and second antenna 400 for data (signal) transmission. Is provided.
第１コア１００は逆Ｕ字状の断面を有し、第２コア２００は第１コア１００の開口端を閉じるように配置されている。第１アンテナ３００及び第２アンテナ４００は、第１コア１００の逆Ｕ字状の断面によって生じた中空室内に対向配置されている。そして、第１コア１００及び第１アンテナ３００はヘッド本体５００側に配置され、第２コア２００及び第２アンテナ４００は、ヘッド本体５００に対し回転軸６００周りに回転するロータリーヘッド７００側に配置されている。すなわち、ロータリーヘッド７００側の第２コア２００及び第２アンテナ４００は、ヘッド本体５００側の第１コア１００及び第１アンテナ３００に対し回転軸６００周りに回転する。特許文献２によれば、このような構成により、ヘッド本体５００に対するロータリーヘッド７００の回転と無関係に、第１コア１００及び第２コア２００を介してエネルギ（電力）をヘッド本体５００からロータリーヘッド７００に伝達できるとともに、第１アンテナ３００及び第２アンテナ４００を介してデータ（信号）をヘッド本体５００とロータリーヘッド７００との間で双方向に交換できるとされている。 The first core 100 has an inverted U-shaped cross section, and the second core 200 is disposed so as to close the opening end of the first core 100. The first antenna 300 and the second antenna 400 are disposed to face each other in the hollow chamber generated by the inverted U-shaped cross section of the first core 100. The first core 100 and the first antenna 300 are disposed on the head body 500 side, and the second core 200 and the second antenna 400 are disposed on the rotary head 700 side that rotates about the rotation axis 600 with respect to the head body 500. ing. That is, the second core 200 and the second antenna 400 on the rotary head 700 side rotate around the rotation axis 600 with respect to the first core 100 and the first antenna 300 on the head body 500 side. According to Patent Document 2, with such a configuration, energy (electric power) is transmitted from the head main body 500 to the rotary head 700 via the first core 100 and the second core 200 regardless of the rotation of the rotary head 700 with respect to the head main body 500. In addition, the data (signal) can be exchanged bidirectionally between the head body 500 and the rotary head 700 via the first antenna 300 and the second antenna 400.
ここで、特許文献２には、エネルギ伝達のために使用される磁界の方向は、データ伝達のために使用される電界の方向に対してほぼ垂直であると記載されている（請求項１２及び段落００１８）。これを図６で説明すると、データ伝達のために使用される電界の方向は、第１アンテナ３００及び第２アンテナ４００の配置からして図６において上下方向であることは明らかである。したがって、エネルギ伝達のために使用される磁界の方向は、図６に示す矢印方向となる。そして第１コア１００及び第２コア２００に巻回するコイルは特許文献２では図示が省略されているが、上記の磁界の方向を得るには図７に示すように巻回する必要がある。すなわち、コイル１１０，２１０は、環状の第１コア１００及び第２コア２００の周方向に巻回する必要があるため、上記の磁界の方向を得るには、図７に示すような単位体を周方向に並べて全体として環状とするか、環状の第１コア１００及び第２コア２００にコイル１１０，２１０を巻回するための貫通孔を周方向に沿って複数形成する必要がある。 Here, Patent Document 2 describes that the direction of the magnetic field used for energy transfer is substantially perpendicular to the direction of the electric field used for data transfer (claims 12 and 12). Paragraph 0018). Referring to FIG. 6, it is clear that the direction of the electric field used for data transmission is the vertical direction in FIG. 6 from the arrangement of the first antenna 300 and the second antenna 400. Therefore, the direction of the magnetic field used for energy transfer is the arrow direction shown in FIG. The coil wound around the first core 100 and the second core 200 is not shown in Patent Document 2, but it is necessary to wind the coil as shown in FIG. 7 in order to obtain the direction of the magnetic field. That is, since the coils 110 and 210 need to be wound in the circumferential direction of the annular first core 100 and the second core 200, a unit body as shown in FIG. It is necessary to form a ring as a whole by arranging them in the circumferential direction, or to form a plurality of through-holes for winding the coils 110 and 210 around the annular first core 100 and second core 200 along the circumferential direction.
いずれの場合も、第１コア１００及び第２コア２００は周方向に不連続となることから、ロータリーヘッド７００（第２コア２００）が回転するときにエネルギを効率的に伝達できる回転位置（エネルギ伝達可能位置）が限られ、第１コア１００及び第２コア２００がエネルギ伝達可能位置にないときにはエネルギの伝達効率が劣化するという問題が生じる。これを図示すると図８のようになり、第２コア２００が実線で示すエネルギ伝達可能位置にあるときはエネルギを効率的に伝達できるが、その途中の破線で示す位置にあるときは、エネルギの伝達効率が劣化する。 In either case, since the first core 100 and the second core 200 are discontinuous in the circumferential direction, a rotational position (energy) that can efficiently transmit energy when the rotary head 700 (second core 200) rotates. When the first core 100 and the second core 200 are not in the energy transmitting position, there is a problem that the energy transmission efficiency is deteriorated. This is shown in FIG. 8, and when the second core 200 is in the energy transferable position indicated by the solid line, energy can be transmitted efficiently, but when it is at the position indicated by the broken line in the middle, Transmission efficiency deteriorates.
本発明が解決しようとする課題は、ヘッド本体にロータリーヘッドが垂直軸周りに回転可能に取り付けられた表面実装機の部品保持ヘッドにおいて、ロータリーヘッドの回転位置にかかわらず、ヘッド本体からロータリーヘッドに非接触式で安定した電力を連続的、効率的に伝送することができるようにすることにある。 The problem to be solved by the present invention is that in a component holding head of a surface mounter in which a rotary head is attached to a head body so as to be rotatable about a vertical axis, the head body is changed to the rotary head regardless of the rotational position of the rotary head. A non-contact type and stable power can be transmitted continuously and efficiently.

Since it is uniformly generated between the first and second coils (see Fig. 2 to be described later), regardless of the rotary position of the rotary head, the non-contact type and stable power by electromagnetic induction from the head body to the rotary head is continuous and efficient. Can be transmitted.

図１は、本発明の一実施例に係る部品保持ヘッドの構成を概念的に示す構成図である。同図に示す部品保持ヘッドは、表面実装機に適用され、その表面実装機において部品供給部から電子部品をピックアップし保持してプリント基板上に移送し、プリント基板上の所定位置に実装する。 FIG. 1 is a configuration diagram conceptually showing the configuration of a component holding head according to an embodiment of the present invention. The component holding head shown in the figure is applied to a surface mounter, and an electronic component is picked up and held from a component supply unit in the surface mounter, transferred onto a printed board, and mounted at a predetermined position on the printed board.
この部品保持ヘッドは、固定配置されたヘッド本体１０と、このヘッド本体１０に対して垂直軸２０周りに回転可能に取り付けられたロータリーヘッド３０と、ヘッド本体１０とロータリーヘッド３０との間に配置された非接触伝送装置４０とを備える。 The component holding head is disposed between the head main body 10 that is fixedly arranged, the rotary head 30 that is rotatably attached to the head main body 10 around the vertical axis 20, and the head main body 10 and the rotary head 30. The contactless transmission device 40 is provided.
ヘッド本体１０は、ロータリーヘッド３０を回転させるサーボモータ１１及びロータリーヘッド３０に配置されているノズル３１の昇降を制御するサーボモータ１２を内蔵している。また、図１では省略しているが、ヘッド本体１０は、サーボモータ１１、１２やロータリーヘッド３０の回転動作を制御するメインコントローラも内蔵している。 The head main body 10 includes a servo motor 11 that rotates the rotary head 30 and a servo motor 12 that controls the raising and lowering of the nozzles 31 arranged in the rotary head 30.

The rotation of the servo motor 11 causes the rotary head 30 to rotate in the R direction around the vertical axis 20 with respect to the head body 10. The rotary head 30 is provided with a plurality of nozzles 31 as holders for holding electronic components along the circumferential direction. Each nozzle 31 can be rotated in the T direction around the axis by an actuator (not shown) made of a servo motor or the like built in the rotary head 30, and can be moved in the Z direction along the axis by the servo motor 12. It is attached to.
非接触伝送装置４０は、第１コア４１及び第２コア４２と、電力伝送のためのコイルとして第１コイル４３及び第２コイル４４と、信号伝送のためのコイルとして第３コイル４５及び第４コイル４６とを備えている。 The non-contact transmission device 40 includes a first core 41 and a second core 42, a first coil 43 and a second coil 44 as coils for power transmission, and a third coil 45 and a fourth coil as coils for signal transmission.

Moreover, it has the annular groove 41b (42b) concentrically with the through-hole 41a (42a), and has the cyclic | annular notch 41c (42c) in the peripheral part of the through-hole 41a (42a). As shown in FIG. 1, the vertical shaft 20 is mounted so as to be fitted through the through holes 41 a and 42 a of the first core 41 and the second core 42. Since the vertical shaft 20 is integrally disposed on the head body 10 side and does not rotate, the vertical shaft 20 is mounted with a slight margin so that it can rotate within the through hole 42a of the second core 42. On the other hand, since the first core 41 is fixed to the head body 10 together with the vertical shaft 20 (rotary head 30), the vertical shaft 20 is fixedly mounted in the through hole 41a of the first core 41.
第１コイル４３は第１コア４１の環状溝４１ｂに沿って巻回され、第２コイル４４は第２コア４２の環状溝４２ｂに沿って巻回されている。すなわち、第１コイル４３及び第２コイル４４は垂直軸２０周りに巻回され、これらは電力伝送のために一定のギャップＧを持って対向配置されている。 The first coil 43 is wound along the annular groove 41 b of the first core 41, and the second coil 44 is wound along the annular groove 42 b of the second core 42. That is, the first coil 43 and the second coil 44 are wound around the vertical axis 20 and are opposed to each other with a certain gap G for power transmission.
また、第３コイル４５は第１コア４１の切欠き４１ｃに沿って巻回され、第４コイル４６は第２コア４２の切欠き４２ｃに沿って巻回されている。すなわち、第３コイル４５及び第４コイル４６は垂直軸２０周りに巻回され、これらは信号伝送のために一定のギャップＧを持って対向配置されている。 The third coil 45 is wound along the notch 41 c of the first core 41, and the fourth coil 46 is wound along the notch 42 c of the second core 42. That is, the third coil 45 and the fourth coil 46 are wound around the vertical axis 20 and are opposed to each other with a certain gap G for signal transmission.
以上の構成において、電力伝送のための磁界Ｍ１は図２に示すように、垂直軸２０周りの第１・第２コイル４３，４４間に均一に発生するので、ロータリーヘッド３０の回転位置にかかわらず、ヘッド本体１０からロータリーヘッド３０に電磁誘導により非接触式で安定した電力を連続的、効率的に伝送することができる。 In the above configuration, the magnetic field M1 for power transmission is uniformly generated between the first and second coils 43 and 44 around the vertical axis 20, as shown in FIG. In addition, non-contact and stable power can be continuously and efficiently transmitted from the head body 10 to the rotary head 30 by electromagnetic induction.
また、信号伝送のための磁界Ｍ２も図２に示すように、垂直軸２０周りの第３・第４コイル４５，４６間に均一に発生するので、ロータリーヘッド３０の回転位置にかかわらず、ヘッド本体１０とロータリーヘッド３０との間で電磁誘導により非接触式で信号を伝送することができる。特に本実施例の場合、信号伝送のための第３コイル４５及び第４コイル４６は電力伝送のための第１コイル４３及び第２コイル４４の内周側、より具体的には貫通孔４１ａ，４２ａの周縁部分に配置されているので、図１に示すように、信号伝送のための磁界Ｍ２の磁路長を短くでき、電力伝送のための磁界Ｍ１との相互干渉（クロストーク）の発生を抑えることができる。 Further, as shown in FIG. 2, the magnetic field M2 for signal transmission is also uniformly generated between the third and fourth coils 45 and 46 around the vertical axis 20, so that the head regardless of the rotational position of the rotary head 30. A signal can be transmitted between the main body 10 and the rotary head 30 in a non-contact manner by electromagnetic induction. Particularly in the case of the present embodiment, the third coil 45 and the fourth coil 46 for signal transmission are the inner peripheral sides of the first coil 43 and the second coil 44 for power transmission, more specifically, through holes 41a, As shown in FIG. 1, the magnetic path length of the magnetic field M2 for signal transmission can be shortened, and mutual interference (crosstalk) with the magnetic field M1 for power transmission occurs as shown in FIG. Can be suppressed.
なお、図４に示すように、信号伝送のための第３コイル４５及び第４コイル４６を、電力伝送のための第１コイル４３及び第２コイル４４の外周側に配置することもできるが、この場合、信号伝送のための磁界Ｍ２の磁路長が長くなり、磁束密度が低くなることから、電力伝送のための磁界Ｍ１との相互干渉（クロストーク）の発生が懸念される。また、磁界Ｍ２の磁束密度を高くするには、第３コイル４５又は第４コイル４６に流す電流を上げるか、その巻き数を増やす必要があり、装置の大型化及び高コスト化を招くという問題が生じる。したがって、信号伝送のための第３コイル４５及び第４コイル４６は、図２に示すように電力伝送のための第１コイル４３及び第２コイル４４の内周側に配置することが好ましい。 As shown in FIG. 4, the third coil 45 and the fourth coil 46 for signal transmission can be disposed on the outer peripheral side of the first coil 43 and the second coil 44 for power transmission, In this case, since the magnetic path length of the magnetic field M2 for signal transmission becomes long and the magnetic flux density becomes low, there is a concern about the occurrence of mutual interference (crosstalk) with the magnetic field M1 for power transmission. Further, in order to increase the magnetic flux density of the magnetic field M2, it is necessary to increase the current flowing through the third coil 45 or the fourth coil 46 or increase the number of turns thereof, leading to an increase in size and cost of the device. Occurs. Therefore, the third coil 45 and the fourth coil 46 for signal transmission are preferably arranged on the inner peripheral side of the first coil 43 and the second coil 44 for power transmission as shown in FIG.
次に、上述した非接触伝送装置４０によって電力及び信号を伝送するための具体的なシステム構成を説明する。図５は、そのシステム構成を示すブロック図である。 Next, a specific system configuration for transmitting power and signals by the contactless transmission device 40 described above will be described. FIG. 5 is a block diagram showing the system configuration.
非接触伝送装置４０は、電力及び信号を伝送するために、送信ユニット４７と受信ユニット４８を備える。そして、送信ユニット４７に図１に示した第１コア４１、第１コイル４３及び第３コイル４５が接続され、受信ユニット４８に第２コア４２、第２コイル４４及び第４コイル４６が接続される。すなわち、送信ユニット４７はヘッド１０側に配置され、受信ユニット４８はロータリーヘッド３０側に配置される。 The non-contact transmission device 40 includes a transmission unit 47 and a reception unit 48 for transmitting power and signals. The first core 41, the first coil 43, and the third coil 45 shown in FIG. 1 are connected to the transmission unit 47, and the second core 42, the second coil 44, and the fourth coil 46 are connected to the reception unit 48. The That is, the transmission unit 47 is disposed on the head 10 side, and the reception unit 48 is disposed on the rotary head 30 side.
まず、電力伝送のためのシステム構成を説明すると、送信ユニット４７に外部からＤＣ４８Ｖの直流電流が供給され、これが高周波送電回路によって１００ｋＨｚの交流電流に変換され第１コイル４３に印加される。電磁誘導により第２コイル４４に誘導電流が生じ、これが受信ユニット４８の整流回路によって直流電流に変換され、更に２個のＤＣ−ＤＣコンバータ（DC-DC CONV.）によって、２４Ｖと５Ｖの直流電力に変換される。このうち、２４Ｖの直流電力は、ロータリーヘッド３０において上述したノズル等を駆動するアクチュエータや各種センサを作動させるために使用され、５Ｖの直流電力は、図５に示す受信ユニット４８の制御回路等を作動させるために使用される。 First, a system configuration for power transmission will be described. A direct current of DC 48 V is supplied to the transmission unit 47 from the outside, and this is converted into an alternating current of 100 kHz by a high frequency power transmission circuit and applied to the first coil 43. Inductive current is generated in the second coil 44 by electromagnetic induction, which is converted into direct current by the rectifier circuit of the receiving unit 48, and further, DC power of 24V and 5V is generated by two DC-DC converters (DC-DC CONV.). Is converted to Of these, 24V DC power is used to operate the actuators and various sensors that drive the nozzles and the like described above in the rotary head 30, and 5V DC power is supplied to the control circuit of the receiving unit 48 shown in FIG. Used to operate.
信号伝送のためのシステム構成は図５に示すとおりで、公知の方法により、ヘッド本体１０からロータリーヘッド３０へ信号を伝送することができる。なお、図５に示す信号伝送のためのシステム構成は、送信ユニット４７及び受信ユニット４８にそれぞれ信号送受信回路を備えているので、ヘッド本体１０とロータリーヘッド３０との間で相互に信号（データ）を伝送することができる。例えば、ヘッド本体１０側からの制御信号、ロータリーヘッド３０側からのセンサ信号等の各種信号を非接触で相互に伝送することができる。 The system configuration for signal transmission is as shown in FIG. 5, and signals can be transmitted from the head body 10 to the rotary head 30 by a known method. In the system configuration for signal transmission shown in FIG. 5, the transmission unit 47 and the reception unit 48 are each provided with a signal transmission / reception circuit, so that signals (data) are mutually transmitted between the head body 10 and the rotary head 30. Can be transmitted. For example, various signals such as a control signal from the head body 10 side and a sensor signal from the rotary head 30 side can be transmitted to each other without contact.
