Description

本発明は、部品実装機のノズル交換装置及び部品実装機に係る。特に、ノズルの自動交換時にノズルを保護することが可能なノズル交換装置、及び、該ノズル交換装置を備えた部品実装機に関する。   The present invention relates to a nozzle replacement device for a component mounter and a component mounter. In particular, the present invention relates to a nozzle replacement device capable of protecting the nozzle during automatic replacement of the nozzle, and a component mounting machine including the nozzle replacement device.

プリント基板上にＩＣ、抵抗、コンデンサ等の多数のチップ部品を高速且つ高精度で自動搭載するための部品実装機では、通常、搭載ヘッドに交換可能に設けた吸着ノズルで、搭載すべき部品をエア吸引により吸着する。この場合、搭載するチップ部品の外径やサイズ等が大幅に変わると、それに応じて吸着ノズルも最適なものに交換する必要が生じる。   In a component mounting machine that automatically mounts a large number of chip components such as ICs, resistors, and capacitors on a printed circuit board at high speed and with high accuracy, the components to be mounted are usually mounted with suction nozzles that can be replaced on the mounting head Adsorbed by air suction. In this case, if the outer diameter or size of the chip component to be mounted is changed significantly, it is necessary to replace the suction nozzle with an optimum one accordingly.

そこで、特許文献１や２では、図１（Ａ）（斜視図）及び（Ｂ）（分解斜視図）に例示する如く、図２に拡大して示すノズル１０のつば１０Ｔより小さな開口２２Ｈが形成されたベース２２と、前記ノズル１０のつば１０Ｔより大きな開口２４Ｈが形成されたスライドベース２４と、前記ノズル１０のつば１０Ｔより上方を側方より挟んでノズル１０を係止するための長穴２６Ｈが形成されたスライドプレート２６と、該スライドプレート２６を図１（Ａ）及び図２（Ａ）に矢印Ａで示す方向にスライドさせるためのシリンダ２８とを有する自動ノズル交換装置２０が提案されている。   Therefore, in Patent Documents 1 and 2, as illustrated in FIGS. 1A (perspective view) and (B) (disassembled perspective view), an opening 22H smaller than the collar 10T of the nozzle 10 shown in FIG. 2 is formed. The base 22 formed, the slide base 24 having an opening 24H larger than the collar 10T of the nozzle 10, and the long hole 26H for engaging the nozzle 10 with the upper side of the collar 10T from the side sandwiched from the side. An automatic nozzle changer 20 is proposed which has a slide plate 26 formed with a cylinder 28 and a cylinder 28 for sliding the slide plate 26 in the direction indicated by arrow A in FIGS. 1 (A) and 2 (A). Yes.

この自動ノズル交換装置において、ノズル１０を搭載ヘッド（図示省略）に装着する時は、シリンダ２８によりスライドプレート２６を矢印Ａ方向に開き、図２（Ｂ）に矢印Ｂで示す如く、搭載ヘッド下端のノズルアウタ１２をノズル１０に押し付けて装着する。該ノズルアウタ１２とノズル１０の結合は、例えば特許文献３や４に記載されたような構成により行なわれる。   In this automatic nozzle changer, when the nozzle 10 is mounted on a mounting head (not shown), the slide plate 26 is opened in the direction of arrow A by the cylinder 28, and as shown by arrow B in FIG. The nozzle outer 12 is attached to the nozzle 10 by pressing it. The nozzle outer 12 and the nozzle 10 are coupled by the configuration described in Patent Documents 3 and 4, for example.

しかしながら、この方式であると、ノズル１０のつば１０Ｔとベース２２の接触面積が大きいため、図２（Ｂ）に示す如く、ノズル１０のつば１０Ｔの下にチップ部品等の異物３０が落ち易く、該異物３０を挟んで傾いたノズル１０をそのままノズルアウタ１２で上から押し付けてしまい、ノズル１０のつば１０Ｔを曲げたり割ったりして破損してしまう恐れがあった。   However, in this method, since the contact area between the collar 10T of the nozzle 10 and the base 22 is large, as shown in FIG. 2 (B), foreign substances 30 such as chip parts are likely to fall under the collar 10T of the nozzle 10, The nozzle 10 tilted with the foreign material 30 in between is pressed as it is with the nozzle outer 12 as it is, and there is a possibility that the collar 10T of the nozzle 10 may be bent or broken and damaged.

一方、本発明に関連するものとして、特許文献５には、ワークホルダのガイド面とワークチャックの搭載面の直交部に圧縮空気吐出溝を設け、ワークの着脱動作により自動的に圧縮空気の吐出方向を制御して、ワークとワークホルダの空隙部及びワークチャックの搭載面の異物の除去を行なうことが記載されている。   On the other hand, as related to the present invention, in Patent Document 5, a compressed air discharge groove is provided in an orthogonal portion of the work holder guide surface and the work chuck mounting surface, and the compressed air is automatically discharged by the work attaching / detaching operation. It describes that the direction is controlled to remove foreign matter from the gap between the work and the work holder and the work chuck mounting surface.

しかしながら、異物を吹き飛ばすための圧縮空気が必要であり、運転経費が増大するという問題点を有していた。   However, there is a problem that compressed air for blowing off the foreign matter is necessary, and the operating cost increases.

本発明は、前記従来の問題点を解消するべくなされたもので、圧縮空気を必要としたり、運転経費を増大させることなく、極めて簡単な構成でノズルを保護することを課題とする。   The present invention has been made to solve the above-described conventional problems, and it is an object of the present invention to protect a nozzle with a very simple configuration without requiring compressed air or increasing operating costs.

本発明は、部品供給部の部品をノズルに吸着して基板に搭載するための部品実装機において、ノズルのつばより小さな開口が形成されたベースと、ノズルのつばわり大きな開口が形成されたスライドベースと、ノズルのつばより上方を側方より挟んでノズルを係止するためのスライドプレートとを備えたノズル交換装置であって、前記ベースとノズルのつばの接触面を、上に凸形状として、前記課題を解決したものである。   The present invention relates to a component mounter for adsorbing components of a component supply unit to a nozzle and mounting them on a substrate, a base in which an opening smaller than the collar of the nozzle is formed, and a slide in which a large opening of the nozzle is formed A nozzle exchange device comprising a base and a slide plate for holding the nozzle by sandwiching the upper side from the side of the nozzle from the side, wherein the contact surface of the base and the collar of the nozzle has a convex shape upward The above-mentioned problem is solved.

前記ベースとノズルのつばの間に、上に凸の断面形状を有するブッシュを挿入し、該ブッシュにより、前記ベースとノズルのつばの接触面を、上に凸形状とすることができる。   A bush having a convex sectional shape is inserted between the base and the collar of the nozzle, and the contact surface of the collar of the base and the nozzle can be convexed upward by the bush.

本発明は、又、前記のノズル交換装置を備えたことを特徴とする部品実装機を提供するものである。   The present invention also provides a component mounter comprising the nozzle exchange device.

本発明によれば、ベースとノズルのつばの接触面を上に凸形状としたので、ノズルのつばを極小面積（線接触）で保持できる。従って、異物がベースとつばの接触部に乗りづらくなり、下方に落下するので、ノズルのつばの破損を防止することができる。   According to the present invention, since the contact surface between the base and the collar of the nozzle is convex upward, the collar of the nozzle can be held in a minimal area (line contact). Accordingly, the foreign matter is difficult to get on the contact portion between the base and the collar and falls downward, so that damage to the collar of the nozzle can be prevented.

以下図面を参照して、本発明の実施形態を詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

本発明が適用される部品実装機は、図３に例示する如く、本発明に係る自動ノズル交換装置２０と、例えば多数のテープフィーダ４２や部品トレイ４４が装着されて電子部品（以下単に部品とも称する）を供給するための、例えば前後２組の部品供給部４０と、部品を搭載する基板８を搬送し固定するための基板搬送部５０と、例えば１０本のノズル１０が交換可能に装着される、例えば前後２つの搭載ヘッド６０と、該搭載ヘッド６０をＸＹ方向に移動するためのＸ軸ガントリ７０Ｘ及びＹ軸ガントリ７０ＹからなるＸＹ移送部７０とを主に備えている。図において、８０は、ノズル１０に吸着された部品を下方から撮像して認識するための、例えば前後２つの部品認識カメラである。   As shown in FIG. 3, the component mounter to which the present invention is applied is an electronic component (hereinafter simply referred to as a component), to which an automatic nozzle changing device 20 according to the present invention and a large number of tape feeders 42 and component trays 44 are mounted. For example, two sets of component supply units 40 for supplying the substrate, a substrate transfer unit 50 for transferring and fixing the substrate 8 on which the components are mounted, and, for example, ten nozzles 10 are exchangeably mounted. For example, it mainly includes two front and rear mounting heads 60 and an XY transfer unit 70 including an X-axis gantry 70X and a Y-axis gantry 70Y for moving the mounting heads 60 in the XY direction. In the figure, reference numeral 80 denotes, for example, two front and rear component recognition cameras for capturing and recognizing a component sucked by the nozzle 10 from below.

本発明に係る自動ノズル交換装置２０の第１実施形態は、図４（分解斜視図）及び図５（ノズル装着状態の要部拡大断面図）に示す如く、自動ノズル交換装置２０のベース２２とノズル１０のつば１０Ｔの間に、上に凸の球面状の断面形状を有するブッシュ７０を挿入するようにしたものである。   The first embodiment of the automatic nozzle changer 20 according to the present invention includes a base 22 of the automatic nozzle changer 20 as shown in FIG. 4 (disassembled perspective view) and FIG. A bush 70 having a spherical convex cross section is inserted between the flanges 10T of the nozzle 10.

この構成において、ノズル１０を装着する際、ノズルアウタ１２により、ノズル１０のつば１０Ｔはブッシュ７０の上に押し付けられる。しかし、ブッシュ７０の上面は球面であるため、ノズル１０のつば１０Ｔとの接触部は極小面積（線接触）であり、異物がブッシュ上面に乗りづらく落ち易い構造になっているため、異物をベース２２とノズル１０のつば１０Ｔの間に挟むことなく、ノズル１０をノズルアウタ１２に装着できる。   In this configuration, when mounting the nozzle 10, the collar 10 </ b> T of the nozzle 10 is pressed onto the bush 70 by the nozzle outer 12. However, since the upper surface of the bush 70 is a spherical surface, the contact portion of the nozzle 10 with the collar 10T has a very small area (line contact), and the foreign material is difficult to get on the upper surface of the bush and is easy to fall. The nozzle 10 can be attached to the nozzle outer 12 without being sandwiched between the flange 10T of the nozzle 22 and the collar 10T.

なお、前記ブッシュ７０の断面形状は円形に限定されず、図６に示す第２実施形態の如く、内側が斜面とされた三角形状のブッシュ７０´であっても良い。   The cross-sectional shape of the bush 70 is not limited to a circle, and may be a triangular bush 70 ′ having an inclined inner surface as in the second embodiment shown in FIG. 6.

あるいは、図７に示す第３実施形態の如く、ブッシュを設けることなく、ベース２２の開口２２Ｈの周囲を盛り上げて、上に凸形状の突起２２Ａを形成しても良い。   Alternatively, as in the third embodiment shown in FIG. 7, the protrusions 22 </ b> A having a convex shape may be formed by raising the periphery of the opening 22 </ b> H of the base 22 without providing a bush.

なお、前記実施形態では、本発明が、前後２組の部品供給部４０、搭載ヘッド６０、部品認識カメラ８０等を有する部品実装機に適用されていたが、本発明の適用対象はこれに限定されず、１組又は３組以上であっても構わない。   In the above embodiment, the present invention is applied to a component mounter having two sets of front and rear component supply units 40, a mounting head 60, a component recognition camera 80, and the like. However, the scope of application of the present invention is limited to this. It may be 1 set or 3 sets or more.
