【産業上の利用分野】[Industrial applications]

本考案はプリント板外観検査機の不良マーキング装置の改善に関するものであ る。 表面実装部品などを高密度に搭載したプリント板の外観検査をX−Yテーブル を使用して自動的に行い良否判定後不良箇所を処置する場合,通常X−Yテーブ ル上にはプリント板を1枚のみ実装固定し順次プリント板全面を検査したあとで 検査判定結果をプリントアウトする。 このプリントアウト内容とプリント板の不良部位を目視により照合確認しなが ら修復などの処置をするのが一般的な方法である。 しかし不良部位の検索及び照合確認作業が前述のように目視にたよるため不良 部位の見まちがい,見落しによる処置もれが発生すると共に検索,照合,確認作 業に多くの時間を要するなどの問題がある。 The present invention relates to improvement of a defective marking device of a printed board visual inspection machine. When a visual inspection of a printed board on which surface-mounted components etc. are mounted at a high density is automatically performed using an XY table and defective parts are treated after a pass / fail judgment, the printed board is usually placed on the XY table. Only one piece is mounted and fixed, and the entire surface of the printed board is inspected in sequence, and then the inspection judgment results are printed out. It is a general method to perform repairs while visually checking and confirming the printout contents and the defective part of the printed board. However, since the defective part search and collation confirmation work rely on visual inspection as described above, the defective part may be mistaken, and the omission of the treatment due to oversight may occur, and much time is required for the search, collation, and confirmation work. There's a problem.

【従来の技術】[Prior art]

以上のような問題点を解決する従来技術を図4により説明する。図4はマーキ ング装置を内蔵した画像処理方式の外観検査装置を示すシステム構成ブロック図 である。 今検査ラインの搬送コンベアでプリント板1をX−Yテーブル2上の決められ た位置まで移送し固定する。プリント板1にはあらかじめシルク印刷又はパター ンランドにより認識マークを設けておき検査開始前に,この認識マークを検査用 ビデオカメラ(以下カメラ)3で検知しX−Yテーブル2の原点位置座標からプ リント板1の基準位置座標をコンピューター4に認識させこれをプリント板1の 座標零点としたあとあらかじめ前記コンピューター4に記憶させた検査順序に従 いX−Yテーブル2をX軸,Y軸方向に移動させプリント板1の全面を順次検査 していく。 A conventional technique for solving the above problems will be described with reference to FIG. FIG. 4 is a system configuration block diagram showing an image processing type visual inspection device having a built-in marking device. Now, the printed board 1 is transferred and fixed to a predetermined position on the XY table 2 by the conveyor of the inspection line. A recognition mark is provided on the printed board 1 in advance by silk printing or pattern land, and before the inspection is started, this recognition mark is detected by the inspection video camera (hereinafter referred to as camera) 3 and is detected from the origin position coordinate of the XY table 2. After making the computer 4 recognize the reference position coordinates of the lint board 1 and setting it as the coordinate zero point of the printed board 1, the XY table 2 is moved in the X-axis and Y-axis directions according to the inspection order stored in the computer 4 in advance. Move and inspect the entire surface of the printed board 1 in order.

【0003】 プリント板1の各被検査部品又は被検査部位(以下被検査部位)5はカメラ3 で映像信号に変換し画像処理部6でデジタル符号化した後,画像メモリ7に格納 しておき随時コンピューター4のCPUに読み出してすでに前記コンピューター 4に入力した判定パラメーターにより良否判定を行う。さらに上記良否判定結果 はX−Yテーブル2の検査位置座標データーと共に一時座標メモリー8に格納す る。前記検査位置座標データーの中で良否判定結果が不良となった位置は不良座 標データーとしあらかじめ前記プリント板1の座標零点から被検査部位5までの 座標データーにマーキングペン9の中心位置座標データーをX軸,Y軸共それぞ れコンピューター4により加算補正しておく。Each inspected part or inspected part (hereinafter, inspected part) 5 of the printed board 1 is stored in the image memory 7 after being converted into a video signal by the camera 3 and digitally encoded by the image processing part 6. The quality is judged according to the judgment parameters which are read out to the CPU of the computer 4 as needed and are already input to the computer 4. Further, the quality judgment result is stored in the temporary coordinate memory 8 together with the inspection position coordinate data of the XY table 2. In the inspection position coordinate data, the position where the pass / fail judgment result is defective is regarded as defective target data, and the center position coordinate data of the marking pen 9 is previously set to the coordinate data from the coordinate zero point of the printed board 1 to the inspected part 5 in advance. The computer 4 adds and corrects both the X axis and the Y axis.

【0004】 次にプリント板1全面の検査が完了した時点で検査順序データーに従い不良判 定となった不良部位のみを順次マーキングペン9の中心位置に移動固定しマーキ ングペン9を押し下げて不良マーク付を行う。 又不良箇所はプリンター20にて不良部位名と不良座標が順次印字される。プ リント板1全面の検査が完了した時点で搬出コンベアにより良品は次工程に不良 品は修正工程に分別搬送し不良品については人手により修復などの処理を行う。Next, when the inspection of the entire surface of the printed board 1 is completed, only the defective portion which has been determined to be defective according to the inspection order data is sequentially moved and fixed to the center position of the marking pen 9 and the marking pen 9 is pushed down to provide the defective mark. I do. As for the defective portion, the defective portion name and the defective coordinates are sequentially printed by the printer 20. When the inspection of the entire surface of the print plate 1 is completed, good products are sorted and conveyed to the next process by the carry-out conveyor, and defective products are separately conveyed to the correction process, and defective products are manually repaired.

【考案が解決しようとする課題】[Problems to be solved by the device]

前述の従来技術は図4に示すようにプリント板1の検査作業と不良マーキング 作業がシリーズワークとなり効率が悪い上,細ピッチ微小化する部品へのマーキ ング作業は位置精度及び部品形状などの制約から必ずしも不良部位そのものにマ ーク付することができずある程度の位置をずらした所にマーク付する必要性が出 てくる。これらの理由から現実的には不良部位個々にマーク付することをあきら め部品単位又は検査ステージ単位の代表マーク付を実施している。このため後工 程においてこの不良処理をする場合プリンター20によって打ち出された不良部 位のリストと現品との照合確認作業はさけられず見落しによる処理もれなどが発 生し,自動検査のメリットを十分に生しきれないなどの欠点がある。 本考案は これらの欠点を解決するため検査作業とマーキング作業を平行して行うと共に細 部不良部位に精度良くマーク付することを目的とする。 As shown in FIG. 4, the above-mentioned conventional technique is inefficient because the inspection work of the printed board 1 and the defective marking work become a series work, and the marking work of a fine pitch minute component is restricted in the position accuracy and the shape of the component. Therefore, it is not always possible to mark the defective part itself, and it becomes necessary to mark the position at a certain position. For these reasons, in actuality, the defective parts are not marked individually, and representative marks are added to each part or inspection stage. For this reason, when performing this defect processing in a later process, the work of collating and checking the list of defective parts punched out by the printer 20 with the actual product is inevitable, resulting in processing omissions due to oversight, which is an advantage of automatic inspection. There are drawbacks such as not being able to fully utilize. In order to solve these drawbacks, the present invention aims to perform inspection work and marking work in parallel and to accurately mark a defective portion in a fine area.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記の目的を達成するため同種,同形の検査済みプリント板とこれか ら検査しようとするプリント板を同一X−Yテーブル上に順次2枚ずつ実装固定 しあらかじめコンピューターに記憶させた検査位置座標とすでに検査済みプリン ト板の不良位置座標により検査作業とマーキング作業を平行して行うようすると 共にマーキング装置に位置補正機能を付加することによりマーキング精度の向上 と検査及び不良処置作業の効率を上げるようにしたものである。 In order to achieve the above-mentioned object, the present invention mounts and fixes inspected printed boards of the same type and shape and printed boards to be inspected on the same XY table two by two in sequence and pre-stored in a computer. The inspection work and the marking work are performed in parallel with the position coordinates and the defective position coordinates of the already-inspected print board, and the position correction function is added to the marking device to improve the marking accuracy and the efficiency of the inspection and the defect treatment work. I tried to raise it.

【作用】[Action]

この結果同一X−Yテーブル上に実装固定した1枚目の検査済プリント板と2 枚目の未検査プリント板は相対的な距離を保ってX軸,Y軸上を動くことになり あらかじめ2枚のプリント板間の位置補正をしておくことにより,検査作業を実 行しながら不良位置座標を検査位置座標に同期させマーキング作業も平行して行 うことができる。又マーキング装置部分にライチング機能をもった小型のX−Y 位置補正機構(以下マーキング補正機構)を付加しあらかじめ被検査部品タイプ 別にマーク付位置を教示しておくことにより代表マーク付から不良部位個別のマ ーク付が可能となる。 As a result, the first inspected printed board and the second uninspected printed board mounted and fixed on the same XY table move on the X axis and Y axis with a relative distance maintained. By correcting the positions between the printed boards, it is possible to synchronize the defective position coordinates with the inspection position coordinates while performing the inspection work, and to perform the marking work in parallel. In addition, a small XY position correction mechanism with a litting function (hereinafter referred to as marking correction mechanism) is added to the marking device part, and the marked position is taught in advance for each type of the inspected part. Marking is possible.

【実施例】【Example】

以下本考案を図1及び図2,3により説明する。図1は本考案の実施例を示す システム構成ブロック図であり,図2,3は本考案実施中のX−Yテーブル上に おけるプリント板の状態図である。 図1のシステム構成で自動的に検査及びマーキング作業を繰返し実行する前に 段取作業として検査基準点とマーキング基準点の相対的な座標位置補正と部品タ イプ別マーキング位置の教示を行う。今図1の検査未実施の同種同形のプリント 板1a,1bをそれぞれ検査定位置及びマーキング定位置に移送固定する。プリ ント板1a,1bには従来技術と同様あらかじめシルク印刷もしくはパターンラ ンドなどで認識マークを設けておきカメラ3でプリント板16の認識マークを, カメラ3と同じ分解能のカメラ16でプリント板1aの認識マークをそれぞれ撮 影し,まず映像切替部19でカメラ3の認識マーク映像をモニター15の画面上 ほぼ中央に来るようX−Yテーブル制御部12,X軸駆動モニター13,Y軸駆 動モーター14などでX−Yテーブル2を移動させる。この画面中央部に設定し た認識マークの位置をプリント板1bの検査基準点とし映像は画像処理部6をと おし画像メモリ部7へ座標データーは座標メモリー部8へ一時格納する。 The present invention will be described below with reference to FIGS. 1 and 2 and 3. FIG. 1 is a block diagram of a system configuration showing an embodiment of the present invention, and FIGS. 2 and 3 are state diagrams of a printed board on an XY table during implementation of the present invention. Before performing the inspection and marking work automatically and repeatedly with the system configuration of Fig. 1, the relative coordinate position correction of the inspection reference point and the marking reference point and the teaching of the marking position for each component type are performed as a setup work. Now, the printed boards 1a and 1b of the same kind and the same shape which have not been inspected in FIG. 1 are transferred and fixed to the inspection fixed position and the marking fixed position, respectively. Similar to the conventional technique, the print plates 1a and 1b are provided with recognition marks in advance by silk printing or pattern landing, and the camera 3 uses the recognition marks of the print board 16 and the camera 16 having the same resolution as the camera 3 prints the print boards 1a. Each of the recognition marks is photographed, and first the XY table control unit 12, the X-axis drive monitor 13, the Y-axis drive is operated so that the image of the recognition mark of the camera 3 is almost centered on the screen of the monitor 15 by the image switching unit 19. The XY table 2 is moved by the motor 14 or the like. The position of the recognition mark set at the center of the screen is used as the inspection reference point of the printed board 1b, and the image is temporarily stored in the image memory unit 7 through the image processing unit 6 and the coordinate data in the coordinate memory unit 8.

【0009】 次に映像切替19でマーキング定位値上のカメラ16の映像つまりプリント板 1aの認識マークをモニター15の画面上前記検査基準点を設定した位置にピッ タリ一致するようX−Yテーブル2を移動しマーキング基準位置を設定する。こ の場合前記検査基準点を設定した位置は画像メモリ7をコンピューター4で読み 出しモニター15上に表示しておく。 検査基準点と同様マーキング基準点のデ ーター類も画像メモリ部7及び座標メモリ部8に格納しコンピューター4でこの 両基準点のずれ量を計測補正,つまり検査基準点とマーキング基準点の座標値を いずれも零とする。これによりプリント板1b上の被検査部位5の位置とプリン ト板1a上の被マーキング部位5の位置は座標的に等価となり検査順序の位置情 報のみで平行してマーキング作業も実施する準備を完了させる。Next, in the image switching 19, the image of the camera 16 on the marking localization value, that is, the recognition mark of the printed board 1a is exactly matched to the position on the screen of the monitor 15 where the inspection reference point is set, so that the XY table 2 is displayed. Move to set the marking reference position. In this case, the position where the inspection reference point is set is read out from the image memory 7 by the computer 4 and displayed on the monitor 15. Similar to the inspection reference point, the data of the marking reference point are also stored in the image memory unit 7 and the coordinate memory unit 8 and the computer 4 measures and corrects the deviation amount between these reference points, that is, the coordinate value of the inspection reference point and the marking reference point. Is zero. As a result, the position of the part to be inspected 5 on the printed board 1b and the position of the part to be marked 5 on the print board 1a are coordinately equivalent, and only the position information of the inspection order is prepared in parallel to perform the marking work. Let it complete.

【0010】 次にプリント板1a,上に搭載した部品タイプ別にカメラ16とモニター15 で映像を確認しながらマーキング位置補正機構18により任意のマーキングポイ ントを教示後設定しこの座標データーを座標メモリ部8に格納する。 以上の作業が終了した時点でプリント1a,1bをX−Yテーブル2から搬出 し以下図2,図3の手順で自動的に繰返しの検査作業とマーキング作業を実施し ていく。Next, while checking the image by the camera 16 and the monitor 15 for each type of component mounted on the printed board 1a, the marking position correcting mechanism 18 sets an arbitrary marking point after teaching and sets the coordinate data in the coordinate memory section. Store in 8. When the above work is completed, the prints 1a and 1b are unloaded from the XY table 2, and then the repetitive inspection work and marking work are automatically performed in the procedure shown in FIGS.

【0011】 今,図2のようにX−Yテーブル2上の検査定位置に検査未実施のプリント1 aを移送固定した後前述の従来技術と同様の方法でプリント板1aの全面を検査 する。検査作業完了の信号により図3のようにプリント板1aをX−Yテーブル 2上のマーキング定位値まで移送すると共に,次の検査未実施のプリント板1b を検査定位置まで移送し図1の状態に検査完了のプリント板1aと検査未実施の プリント板1bを固定し検査とマーキング作業を同時に平行して開始する。プリ ント板1bの検査作業方法は前述の従来技術と同様である。以下は検査完了プリ ント板1aのマーキング作業方法を同じく図1で説明する。Now, as shown in FIG. 2, the uninspected print 1 a is transferred and fixed to the inspection fixed position on the XY table 2, and then the entire surface of the printed board 1 a is inspected by the same method as the above-mentioned conventional technique. . In response to the inspection completion signal, the printed board 1a is moved to the marking localization value on the XY table 2 as shown in FIG. 3, and the next uninspected printed board 1b is moved to the inspected position and the state shown in FIG. Then, the printed board 1a which has been inspected and the printed board 1b which has not been inspected are fixed, and the inspection and the marking work are simultaneously started in parallel. The method for inspecting the print plate 1b is the same as that of the above-mentioned conventional technique. Hereinafter, a method of marking the inspection completed print plate 1a will be described with reference to FIG.

【0012】 検査完了しX−Yテーブル2上のマーキング定位値に固定したプリント板1a はまずカメラ16で認識マークを検出し前述の段取作業で設定したマーキング基 準点の座標値とのずれ量を確認する。ずれ量が規格外の時はマーキング補正制御 部17によりマーキング位置補正機構18をずれ量分移動させる。プリント板1 aはすでに検査完了しているため良否判定結果とその位置座標は座標メモリ部8 に格納されている。 不良判定となった座標にはさらに部品タイプ別のマーキングポイントを教示し た移動量を加算しマーキング補正機構18によりマーキングヘッド11を移動さ せ待機させておく。今検査順序と不良判定となった座標が一致した時マーキング 制御10によりマーキングペン9を押下して不良ポイントにマーク付を行う又イ ンクジェット方式のマーキングヘッド11の場合はノズル弁を開きインクを噴射 してマーク付を行う。The printed board 1a which has been inspected and fixed to the marking localization value on the XY table 2 first detects the recognition mark by the camera 16 and shifts from the coordinate value of the marking reference point set in the above-mentioned setup work. Check the amount. When the deviation amount is out of the standard, the marking correction control unit 17 moves the marking position correction mechanism 18 by the deviation amount. Since the printed board 1 a has already been inspected, the pass / fail judgment result and its position coordinates are stored in the coordinate memory unit 8. To the coordinates determined to be defective, the movement amount at which the marking point for each component type is taught is added, and the marking head 11 is moved by the marking correction mechanism 18 to stand by. When the inspection order and the coordinates that have been judged as defective coincide with each other, the marking pen 10 is pressed by the marking control 10 to mark the defective point. In the case of the ink jet type marking head 11, the nozzle valve is opened and ink is supplied. Jet and mark.
