Abstract
The production management system: measures a feeder stop time, which is the amount of time a tape feeder (12) set on a component mounting machine (10) is waiting in a stopped state; uses a humidity detection means (a humidity sensor (22)) to detect the humidity of air inside the component mounting machine (10) where the main body-side portion (the vicinity of the position where a cover tape (15) is peeled) of the tape feeder (12) is present; and manages granting/prohibition of use of a component supply tape (13) mounted on the tape feeder (12) on the basis of the feeder stop time and the humidity. As a result, the amount of time (feeder stop time) during which the cover tape (15) of the component supply tape (13) is exposed to dry air in the vicinity of the peeling position and the humidity of the air are taken into consideration when monitoring whether or not a failure caused by static electricity is likely to occur when peeling away the cover tape (15) from the component supply tape (13). If a failure caused by static electricity is likely to occur, use of the component supply tape (13) is prohibited.
Description
本発明は、部品供給テープを装着したテープフィーダを部品実装機にセットして、該テープフィーダで該部品供給テープの先端側からカバーテープ(トップテープ、カバーフィルム、トップフィルムとも呼ばれる)を剥離して該部品供給テープ内の電子部品を露出させながら該部品供給テープを部品吸着位置へ送り、該部品実装機の吸着ノズルで該部品供給テープ内の電子部品を吸着して回路基板に実装する部品実装機の生産管理システムに関する発明である。
The present invention sets a tape feeder on which a component supply tape is mounted on a component mounter, and peels a cover tape (also called a top tape, a cover film, or a top film) from the front end side of the component supply tape with the tape feeder. The component supply tape is sent to the component suction position while the electronic component in the component supply tape is exposed, and the electronic component in the component supply tape is sucked by the suction nozzle of the component mounting machine and mounted on the circuit board. The invention relates to a production management system for a mounting machine.
部品実装機にセットしたテープフィーダにおいては、部品供給テープの上面からカバーテープを剥離する際に静電気が発生して、その静電気によって、電子部品がカバーテープに貼り付いたり、部品供給テープのキャビティ(部品収容凹部)から飛び出したりして、部品実装機の吸着ノズルによる電子部品の吸着が安定しなかったり、また、静電気で電子部品の内部回路が壊れる可能性もある。近年の電子部品は微小化・軽量化が進み、部品供給テープからカバーテープを剥離する際に発生する静電気による不具合が発生しやすい環境となっている。
In a tape feeder set in a component mounter, static electricity is generated when the cover tape is peeled off from the upper surface of the component supply tape, and the static electricity causes the electronic component to stick to the cover tape or the component supply tape cavity ( There is a possibility that the electronic component will not be stably adsorbed by the adsorbing nozzle of the component mounting machine, and the internal circuit of the electronic component may be broken by static electricity. In recent years, electronic components have become smaller and lighter, and an environment in which troubles due to static electricity generated when the cover tape is peeled off from the component supply tape is likely to occur.
そこで、特許文献1(実開昭60-27499号公報)では、部品供給テープから剥離したカバーテープの帯電による静電圧を検出して、その検出電圧よりも大きい同極性の高電圧をテープ送り機構のスプロケットローラに印加して、静電気による部品供給不良を防止するようにしている。
Therefore, in Patent Document 1 (Japanese Utility Model Publication No. 60-27499), a static voltage due to charging of the cover tape peeled off from the component supply tape is detected, and a high voltage of the same polarity larger than the detected voltage is detected by the tape feeding mechanism This is applied to the sprocket roller of the machine to prevent defective parts supply due to static electricity.
また、特許文献2(実開平5-57900号公報)では、一端がアースされた導電具ののブラシ部を部品吸着位置付近で上方から部品供給テープのキャリアテープに接触させることで、キャリアテープに帯電した静電気を導電具を介してアース側に逃がしてキャリアテープから静電気を除去すようにしている。
Further, in Patent Document 2 (Japanese Utility Model Publication No. 5-57900), the brush portion of a conductive tool grounded at one end is brought into contact with the carrier tape of the component supply tape from above in the vicinity of the component suction position. The charged static electricity is released to the ground side through a conductive tool to remove the static electricity from the carrier tape.
また、特許文献3(特開2012-195401号公報)では、部品供給テープが通るテープ通路のうちの少なくとも一部に、該部品供給テープと接触又は近接して該部品供給テープに帯電した静電気を取り除く除電シートを設けて、部品供給テープに帯電した静電気を取り除くようにしている。
Further, in Patent Document 3 (Japanese Patent Laid-Open No. 2012-195401), at least a part of a tape passage through which a component supply tape passes is charged with static electricity charged on the component supply tape in contact with or in proximity to the component supply tape. A static elimination sheet is provided to remove static electricity charged on the component supply tape.
一般に、テープフィーダに装着した部品供給テープの周辺の空気が乾燥するほど、部品供給テープからカバーテープを剥離する際に静電気が発生しやすくなる。また、部品供給テープが乾燥状態の空気に晒される時間が長くなるほど、部品供給テープに帯電する静電気量が増加する傾向がある。このため、上記特許文献1~3の静電気対策を施しても、部品供給テープが乾燥状態の空気に晒される時間が長くなると、静電気を除去する能力が不足して、特に、微小で軽量な電子部品を収容した部品供給テープでは、上述した不具合が発生しやすい。
Generally, the more the air around the component supply tape mounted on the tape feeder dries, the more easily static electricity is generated when the cover tape is peeled from the component supply tape. Further, as the time during which the component supply tape is exposed to dry air becomes longer, the amount of static electricity charged on the component supply tape tends to increase. For this reason, even if the countermeasures against static electricity described in Patent Documents 1 to 3 are taken, if the time for which the component supply tape is exposed to dry air becomes long, the ability to remove static electricity is insufficient, In the component supply tape containing the components, the above-described problems are likely to occur.
そこで、本発明が解決しようとする課題は、テープフィーダに装着した部品供給テープが乾燥状態の空気に晒される時間が長くなることによる不具合を効果的に防止できる部品実装機の生産管理システムを提供することである。
Therefore, the problem to be solved by the present invention is to provide a production management system for a component mounting machine that can effectively prevent problems caused by the time that the component supply tape mounted on the tape feeder is exposed to dry air. It is to be.
上記課題を解決するために、本発明は、部品供給テープを装着したテープフィーダを部品実装機にセットして、該テープフィーダで該部品供給テープの先端側からカバーテープを剥離して該部品供給テープ内の電子部品を露出させながら該部品供給テープを部品吸着位置へ送り、該部品実装機の吸着ノズルで該部品供給テープ内の電子部品を吸着して回路基板に実装する部品実装機の生産管理システムにおいて、前記テープフィーダが停止状態で待機する時間(以下「フィーダ停止時間」という)を計測するフィーダ停止時間計測手段と、前記テープフィーダが存在する空気の湿度を検出する湿度検出手段と、前記フィーダ停止時間計測手段により計測したフィーダ停止時間と前記湿度検出手段で検出した湿度とに基づいて前記テープフィーダに装着されている部品供給テープの使用の許可/禁止を管理するフィーダ管理手段とを備えた構成としたものである。
In order to solve the above problems, the present invention sets a tape feeder on which a component supply tape is mounted on a component mounter, and peels the cover tape from the front end side of the component supply tape with the tape feeder to supply the component. Production of a component mounter that feeds the component supply tape to a component suction position while exposing the electronic component in the tape, and sucks the electronic component in the component supply tape by the suction nozzle of the component mounter and mounts it on the circuit board. In the management system, a feeder stop time measuring means for measuring a time for which the tape feeder waits in a stopped state (hereinafter referred to as “feeder stop time”), a humidity detecting means for detecting the humidity of air in which the tape feeder exists, Based on the feeder stop time measured by the feeder stop time measuring means and the humidity detected by the humidity detecting means, It is obtained by a structure in which a feeder managing means for managing permission / prohibition of use of the component supply tape is attached to da.
一般に、テープフィーダに装着した部品供給テープの周辺の空気が乾燥するほど、部品供給テープからカバーテープを剥離する際に静電気が発生しやすくなって、静電気による不具合が発生しやすくなる。この静電気による不具合は、カバーテープ剥離位置付近で発生するため、テープフィーダが停止状態で待機するフィーダ停止時間が長くなるほど、部品供給テープのカバーテープがカバーテープ剥離位置付近で乾燥状態の空気に晒される時間が長くなって、カバーテープを剥離する際に発生する静電気が増加して、静電気による不具合が増える傾向がある。
Generally, as the air around the component supply tape mounted on the tape feeder dries, static electricity is more likely to occur when the cover tape is peeled off from the component supply tape, and problems due to static electricity are more likely to occur. Since this static electricity failure occurs near the cover tape peeling position, the longer the feeder stop time when the tape feeder is stopped, the more the component supply tape cover tape is exposed to dry air near the cover tape peeling position. When the cover tape is peeled off, the static electricity generated when the cover tape is peeled off increases, and the troubles due to static electricity tend to increase.
この特性に着目して、本発明は、テープフィーダが停止状態で待機するフィーダ停止時間を計測すると共に、テープフィーダが存在する空気の湿度を検出し、フィーダ停止時間と湿度に基づいてテープフィーダに装着されている部品供給テープの使用の許可/禁止を管理するようにしたものである。これにより、部品供給テープのカバーテープが剥離位置付近で乾燥状態の空気に晒される時間(フィーダ停止時間)と空気の湿度の両方を考慮して、部品供給テープからカバーテープを剥離する際に静電気による不具合が発生しやすい状態になっているか否かを監視して、静電気による不具合が発生しやすい状態になったときに部品供給テープの使用を禁止することが可能となり、部品供給テープが乾燥状態の空気に晒される時間が長くなることによる不具合を効果的に防止できる。
Paying attention to this characteristic, the present invention measures the feeder stop time when the tape feeder is in a stopped state, detects the humidity of the air where the tape feeder exists, and applies the tape feeder to the tape feeder based on the feeder stop time and humidity. The permission / prohibition of use of the mounted component supply tape is managed. As a result, taking into account both the time during which the cover tape of the component supply tape is exposed to dry air near the peeling position (feeder stop time) and the humidity of the air, It is possible to prohibit the use of the component supply tape when the device is in a state where it is likely to cause a malfunction due to static electricity, and the component supply tape is in a dry state. It is possible to effectively prevent problems caused by the prolonged exposure to air.
具体的には、前記フィーダ管理手段は、前記フィーダ停止時間計測手段により計測したフィーダ停止時間が所定時間以上で且つ前記湿度検出手段で検出した湿度が所定湿度以下となったときに前記テープフィーダに装着されている部品供給テープの使用を禁止するようにしても良い。ここで、「所定時間」や「所定湿度」は、予め決められた一定値(固定値)としても良いし、部品供給テープの材質や部品種等によって変化させるようにしても良い。部品供給テープの材質や部品種等によって、静電気による不具合の発生率が変化するためである。
Specifically, the feeder management means applies the tape feeder to the tape feeder when the feeder stop time measured by the feeder stop time measuring means is a predetermined time or more and the humidity detected by the humidity detection means becomes a predetermined humidity or less. The use of the mounted component supply tape may be prohibited. Here, the “predetermined time” and “predetermined humidity” may be a predetermined constant value (fixed value), or may be changed depending on the material of the component supply tape, the component type, and the like. This is because the rate of occurrence of defects due to static electricity changes depending on the material of the component supply tape, the component type, and the like.
或は、前記フィーダ管理手段は、前記フィーダ停止時間計測手段により計測したフィーダ停止時間が前記湿度検出手段で検出した湿度に応じて設定した所定時間以上となったときにテープフィーダに装着されている部品供給テープの使用を禁止するようにしても良い。この場合、空気の湿度が低いほど(つまり空気が乾燥するほど)、部品供給テープからカバーテープを剥離する際に静電気が発生しやすくなるため、前記湿度検出手段で検出した湿度が低いほど、部品供給テープの使用を禁止するまでのフィーダ停止時間(所定時間)を短い時間に設定するようにすれば良い。
Alternatively, the feeder management means is mounted on the tape feeder when the feeder stop time measured by the feeder stop time measuring means reaches or exceeds a predetermined time set according to the humidity detected by the humidity detection means. The use of the component supply tape may be prohibited. In this case, as the humidity of the air is lower (that is, the air is dried), static electricity is more likely to occur when the cover tape is peeled off from the component supply tape. Therefore, the lower the humidity detected by the humidity detecting means, The feeder stop time (predetermined time) until the use of the supply tape is prohibited may be set to a short time.
また、前記湿度検出手段は、部品実装機の内側の空気の湿度を検出するようにすると良い。部品供給テープからカバーテープを剥離する位置(部品吸着位置付近)は、部品実装機の内側に位置し、部品実装機の外側よりも空気の温度が高く、空気が乾燥しているため、部品実装機の内側の空気の湿度を検出するようにすれば、静電気による不具合が発生するカバーテープ剥離位置付近の空気の湿度を精度良く検出することができ、静電気による不具合が発生しやすい状態であるか否かを精度良く監視することができる。
Further, the humidity detecting means may detect the humidity of the air inside the component mounter. The position where the cover tape is peeled off from the component supply tape (near the component suction position) is located inside the component mounter, and the air temperature is higher than the outside of the component mounter and the air is dry. By detecting the humidity of the air inside the machine, it is possible to accurately detect the humidity of the air near the cover tape peeling position where trouble due to static electricity occurs, and whether the trouble due to static electricity is likely to occur. Whether or not can be accurately monitored.
ところで、複数のテープフィーダがセットされた部品実装機においては、テープフィーダ毎にフィーダ停止時間が異なるため、部品供給テープのカバーテープが剥離位置付近で乾燥状態の空気に晒される時間もテープフィーダ毎に異なる。
By the way, in a component mounter in which a plurality of tape feeders are set, the feeder stop time differs for each tape feeder, so the time for the cover tape of the component supply tape to be exposed to dry air near the peeling position is also different for each tape feeder. Different.
そこで、複数のテープフィーダがセットされた部品実装機においては、前記フィーダ停止時間計測手段は、テープフィーダ毎にフィーダ停止時間を計測し、前記フィーダ管理手段は、テープフィーダ毎にフィーダ停止時間と湿度に基づいて部品供給テープの使用の許可/禁止を管理するようにすれば良い。このようにすれば、部品実装機にセットされたテープフィーダ毎に静電気による不具合が発生しやすい状態になっているか否かを監視して、静電気による不具合が発生しやすい状態になったテープフィーダについてのみ部品供給テープの使用を禁止することができる。
Therefore, in a component mounting machine in which a plurality of tape feeders are set, the feeder stop time measuring unit measures the feeder stop time for each tape feeder, and the feeder management unit is configured to reduce the feeder stop time and humidity for each tape feeder. Based on the above, permission / prohibition of use of the component supply tape may be managed. In this way, the tape feeder set in the component mounter is monitored for whether or not it is prone to malfunction due to static electricity, and the tape feeder that is prone to malfunction due to static electricity Only the use of parts supply tape can be prohibited.
ところで、テープフィーダに装着可能な複数の部品種の部品供給テープの中には、カバーテープを剥離する際に発生する静電気による不具合が発生しない電子部品(例えば大型部品等)も存在する。静電気による不具合が発生しない部品種の部品供給テープについては、使用の許可/禁止を管理する必要はない。従って、テープフィーダに装着可能な複数の部品種の部品供給テープのうち、カバーテープを剥離する際に発生する静電気による不具合が発生しない部品種の部品供給テープは、管理対象とはせず、静電気による不具合が発生する可能性のある部品種の部品供給テープのみを管理対象とし、前記フィーダ管理手段は、管理対象となる部品種の部品供給テープを装着したテープフィーダについてのみ当該部品供給テープの使用の許可/禁止を管理し、管理対象とならない部品種の部品供給テープについては当該部品供給テープの使用を許可するようにすると良い。このようにすれば、静電気による不具合が発生しない部品種の部品供給テープの管理を行わずに済み、その分、部品供給テープの管理に要する処理負荷を軽減できる。
By the way, among the component supply tapes of a plurality of component types that can be mounted on the tape feeder, there are electronic components (for example, large components) that are free from problems caused by static electricity that occurs when the cover tape is peeled off. It is not necessary to manage permission / prohibition of use of a component supply tape of a component type that does not cause problems due to static electricity. Therefore, among component supply tapes of a plurality of component types that can be mounted on the tape feeder, component supply tapes of component types that do not cause problems due to static electricity that occurs when the cover tape is peeled off are not subject to management. Only the component supply tape of the component type that may cause a malfunction due to the above is managed, and the feeder management means uses the component supply tape only for the tape feeder equipped with the component supply tape of the component type to be managed. It is preferable to manage the permission / prohibition of the component and to permit the use of the component supply tape of the component type that is not the management target. In this way, it is not necessary to manage the component supply tape of a component type that does not cause a problem due to static electricity, and accordingly, the processing load required for managing the component supply tape can be reduced.
更に、前記フィーダ管理手段は、使用禁止と判定した部品供給テープからの電子部品の吸着を停止すると共に、表示及び/又は音声で作業者に警告するようにすると良い。このようにすれば、使用禁止と判定した部品供給テープを作業者に早期に交換させるように促すことができ、静電気による不具合をより確実に防止できる。
Furthermore, the feeder management means may stop the suction of the electronic component from the component supply tape determined to be prohibited and warn the operator by display and / or voice. In this way, it is possible to prompt the operator to replace the component supply tape determined to be prohibited from use at an early stage, and it is possible to more reliably prevent a malfunction due to static electricity.

A plurality of tape feeders 12 are set side by side on the feeder set base 11 of the component mounting machine 10. Each tape feeder 12 is provided with a reel 14 around which a component supply tape 13 is wound, and the component supply tape 13 is sent from the reel 14 to a component suction position, and from the upper surface of the component supply tape 13 before the component suction position.

To implement.
テープフィーダ12の先端から排出される空のキャリアテープ16は、テープガイド通路17によって下方へ湾曲させて案内され、テープ切断機構(図示せず)で切断されてシュート18を滑落して空テープ回収ボックス19内に回収される。テープフィーダ12の部品吸着位置の手前でキャリアテープ16から剥離されたカバーテープ15は、テープフィーダ12から垂れ下がってその真下に位置する廃棄テープ回収ボックス19内に回収される。
The empty carrier tape 16 discharged from the tip of the tape feeder 12 is guided by being bent downward by the tape guide passage 17, cut by a tape cutting mechanism (not shown), and slid down the chute 18 to collect the empty tape. It is collected in the box 19. The cover tape 15 peeled off from the carrier tape 16 before the component suction position of the tape feeder 12 hangs down from the tape feeder 12 and is collected in a waste tape collection box 19 positioned immediately below the tape.
部品実装機10の前面には、前面カバー21が開閉可能に設けられ、該前面カバー21を閉じた状態では、部品実装機10の内側の空間がほぼ密閉され、フィーダセット台11にセットしたテープフィーダ12の本体側の部分(カバーテープ15の剥離位置付近)が部品実装機10の内側に位置し、リール14側の部分が部品実装機10の外側に位置している。部品実装機10の内側には、テープフィーダ12の本体側の部分が存在する部品実装機10の内側の空気の湿度を検出する湿度センサ22(湿度検出手段)が設置されている。
A front cover 21 is provided on the front surface of the component mounter 10 so that the front cover 21 can be opened and closed. When the front cover 21 is closed, the space inside the component mounter 10 is almost sealed and set on the feeder set base 11. A portion of the feeder 12 on the main body side (near the peeling position of the cover tape 15) is located inside the component mounter 10, and a portion on the reel 14 side is located outside the component mounter 10. Inside the component mounter 10, a humidity sensor 22 (humidity detection means) that detects the humidity of the air inside the component mounter 10 where the main body side portion of the tape feeder 12 exists is installed.

Produce.
部品実装機10の制御装置31は、コンピュータを主体として構成され、キーボード、マウス、タッチパネル等の入力装置32と、液晶ディスプレイ、CRT等の表示装置33と、部品実装機制御プログラムや後述する図3及び図4のテープフィーダ管理プログラム等を記憶した記憶装置34等が接続されている。部品実装機10の制御装置31は、吸着ノズルを保持する実装ヘッド(図示せず)をX-Y-Z方向に移動させる実装ヘッド移動装置35と、電子部品を実装する回路基板を搬送する基板搬送装置36と、吸着ノズルに吸着した電子部品を下方から撮像するパーツカメラ37と、回路基板の基準位置マーク等を上方から撮像するマークカメラ38等の動作を制御して、電子部品実装基板を生産する。 Next, the configuration of the control system of the
The
図示はしないが、電子部品実装基板を生産する生産ラインには、1台又は複数台の部品実装機10の他に、回路基板に半田パターンを印刷する半田印刷機や、リフロー半田付けするリフロー炉や、電子部品の実装状態を検査する検査装置等が回路基板の搬送経路に沿って配列され、生産管理用のホストコンピュータ41によって生産ライン全体の各装置の生産が管理される。
Although not shown, in the production line for producing the electronic component mounting board, in addition to one or a plurality of component mounting machines 10, a solder printer for printing a solder pattern on a circuit board, or a reflow furnace for reflow soldering In addition, an inspection device or the like for inspecting the mounting state of the electronic components is arranged along the circuit board conveyance path, and production of each device in the entire production line is managed by the production management host computer 41.
部品実装機10の制御装置31(又はホストコンピュータ41)は、図3及び図4のテープフィーダ管理プログラムを実行することで、部品供給テープ13にセットしたテープフィーダ12が停止状態で待機する時間(以下「フィーダ停止時間」という)を計測するフィーダ停止時間計測手段として機能すると共に、計測したフィーダ停止時間と湿度センサ22で検出した湿度とに基づいてテープフィーダ12に装着されている部品供給テープ13の使用の許可/禁止を管理するフィーダ管理手段としても機能する。
The control device 31 (or the host computer 41) of the component mounter 10 executes the tape feeder management program shown in FIGS. 3 and 4 so that the tape feeder 12 set on the component supply tape 13 waits in a stopped state ( The component supply tape 13 is mounted on the tape feeder 12 based on the measured feeder stop time and the humidity detected by the humidity sensor 22. It also functions as a feeder management means for managing permission / prohibition of use of.
一般に、テープフィーダ12に装着した部品供給テープ13の周辺の空気が乾燥するほど、部品供給テープ13からカバーテープ14を剥離する際に静電気が発生しやすくなって、静電気による不具合が発生しやすくなる。この静電気による不具合は、カバーテープ15の剥離位置付近で発生するため、テープフィーダ12が停止状態で待機するフィーダ停止時間が長くなるほど、部品供給テープ13のカバーテープ14が剥離位置付近で乾燥状態の空気に晒される時間が長くなって、カバーテープ14を剥離する際に発生する静電気が増加して、静電気による不具合が増える傾向がある。
Generally, as the air around the component supply tape 13 mounted on the tape feeder 12 is dried, static electricity is more likely to be generated when the cover tape 14 is peeled from the component supply tape 13, and problems due to static electricity are more likely to occur. . Since the trouble due to static electricity occurs near the peeling position of the cover tape 15, the cover tape 14 of the component supply tape 13 becomes dry near the peeling position as the feeder stop time in which the tape feeder 12 is in a stopped state becomes longer. There is a tendency that the time of exposure to air becomes longer, static electricity generated when the cover tape 14 is peeled off, and defects due to static electricity increase.
この特性に着目して、本実施例では、テープフィーダ12が停止状態で待機するフィーダ停止時間を計測すると共に、テープフィーダ12の本体側の部分(カバーテープ15の剥離位置付近)が存在する部品実装機10の内側の空気の湿度を検出し、部品供給テープ13のカバーテープ15が剥離位置付近で乾燥状態の空気に晒される時間と空気の湿度の両方を考慮して、部品供給テープ13からカバーテープ15を剥離する際に静電気による不具合が発生しやすい状態になっているか否かを監視して、静電気による不具合が発生しやすい状態になったときに部品供給テープ13の使用を禁止するようにしている。
Focusing on this characteristic, in this embodiment, the feeder stop time during which the tape feeder 12 is stopped is measured, and a part on the main body side of the tape feeder 12 (near the peeling position of the cover tape 15) is present. From the component supply tape 13, the humidity of the air inside the mounting machine 10 is detected and the cover tape 15 of the component supply tape 13 is exposed to dry air near the peeling position and the air humidity is taken into consideration. When the cover tape 15 is peeled off, it is monitored whether or not a failure due to static electricity is likely to occur, and the use of the component supply tape 13 is prohibited when the failure due to static electricity is likely to occur. I have to.
尚、本実施例では、部品供給テープ13の使用を禁止する機能の他に、カバーテープ15の剥離動作を低速にする機能を任意に選択できるように構成され、作業者が後者の機能を選択した場合に、計測したフィーダ停止時間と湿度とに基づいてカバーテープ15を剥離する際に静電気による不具合が発生しやすい状態になったと判断したときに、カバーテープ15の剥離動作を低速にすることができるようになっている。カバーテープ15の剥離動作を低速にすることで、静電気の発生を少なくすることができる。
In this embodiment, in addition to the function of prohibiting the use of the component supply tape 13, it is possible to arbitrarily select the function of slowing the peeling operation of the cover tape 15, and the operator selects the latter function. In this case, when it is determined that a problem due to static electricity is likely to occur when the cover tape 15 is peeled off based on the measured feeder stop time and humidity, the peeling operation of the cover tape 15 is slowed down. Can be done. Generation of static electricity can be reduced by slowing the peeling operation of the cover tape 15.
ところで、複数のテープフィーダ12がセットされた部品実装機10においては、テープフィーダ12毎にフィーダ停止時間が異なるため、部品供給テープ13のカバーテープ15が剥離位置付近で乾燥状態の空気に晒される時間もテープフィーダ15毎に異なる。
By the way, in the component mounting machine 10 in which the plurality of tape feeders 12 are set, since the feeder stop time is different for each tape feeder 12, the cover tape 15 of the component supply tape 13 is exposed to dry air near the peeling position. The time also differs for each tape feeder 15.
そこで、複数のテープフィーダ12がセットされた部品実装機10においては、テープフィーダ13毎にフィーダ停止時間を計測し、テープフィーダ13毎にフィーダ停止時間と湿度に基づいて部品供給テープ13の使用の許可/禁止を管理するようにしている。このようにすれば、部品実装機10にセットされたテープフィーダ12毎に静電気による不具合が発生しやすい状態になっているか否かを監視して、静電気による不具合が発生しやすい状態になったテープフィーダ12についてのみ部品供給テープ13の使用を禁止することができる。
Therefore, in the component mounter 10 in which a plurality of tape feeders 12 are set, the feeder stop time is measured for each tape feeder 13, and the use of the component supply tape 13 is used for each tape feeder 13 based on the feeder stop time and humidity. The permission / prohibition is managed. In this way, the tape feeder 12 set in the component mounter 10 is monitored for whether or not a trouble due to static electricity is likely to occur, and the tape that is likely to cause a trouble due to static electricity. The use of the component supply tape 13 can be prohibited only for the feeder 12.
本実施例では、計測したフィーダ停止時間が所定時間以上で且つ湿度センサ22で検出した湿度が所定湿度以下となったときに、テープフィーダ12に装着されている部品供給テープ13の使用を禁止するようにしている。ここで、「所定時間」や「所定湿度」は、予め決められた一定値(固定値)としても良いし、部品供給テープ13の材質や部品種等によって変化させるようにしても良い。部品供給テープ13の材質や部品種等によって、静電気による不具合の発生率が変化するためである。
In this embodiment, when the measured feeder stop time is longer than a predetermined time and the humidity detected by the humidity sensor 22 is lower than the predetermined humidity, the use of the component supply tape 13 mounted on the tape feeder 12 is prohibited. I am doing so. Here, the “predetermined time” and the “predetermined humidity” may be a predetermined value (fixed value) determined in advance, or may be changed depending on the material, the type of component, and the like of the component supply tape 13. This is because the rate of occurrence of defects due to static electricity changes depending on the material, component type, and the like of the component supply tape 13.
ところで、テープフィーダ12に装着可能な複数の部品種の部品供給テープ13の中には、カバーテープ15を剥離する際に発生する静電気による不具合が発生しない電子部品(例えば大型部品等)も存在する。静電気による不具合が発生しない部品種の部品供給テープ13については、使用の許可/禁止を管理する必要はない。
By the way, among the component supply tapes 13 of a plurality of component types that can be mounted on the tape feeder 12, there are electronic components (for example, large components) that are free from problems caused by static electricity that occurs when the cover tape 15 is peeled off. . It is not necessary to manage permission / prohibition of use of the component supply tape 13 of a component type that does not cause a problem due to static electricity.
そこで、本実施例では、テープフィーダ12に装着可能な複数の部品種の部品供給テープ13のうち、カバーテープ15を剥離する際に発生する静電気による不具合が発生しない部品種の部品供給テープ13は、管理対象とはせず、静電気による不具合が発生する可能性のある部品種の部品供給テープ13のみを管理対象とし、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12についてのみ当該部品供給テープ13の使用の許可/禁止を管理し、管理対象とならない部品種の部品供給テープ13については当該部品供給テープ13の使用を許可するようにしている。このようにすれば、静電気による不具合が発生しない部品種の部品供給テープ13の管理を行わずに済み、その分、部品供給テープ13の管理に要する処理負荷を軽減できる。
Therefore, in the present embodiment, among the component supply tapes 13 of a plurality of component types that can be mounted on the tape feeder 12, the component supply tape 13 of a component type that does not cause trouble due to static electricity that occurs when the cover tape 15 is peeled off is Only the component feeder tape 13 of a component type that is not subject to management and may cause a malfunction due to static electricity is managed, and only the tape feeder 12 having the component supply tape 13 of the component type to be managed is mounted. The permission / prohibition of the use of the component supply tape 13 is managed, and the use of the component supply tape 13 is permitted for the component supply tape 13 of a component type that is not a management target. In this way, it is not necessary to manage the component supply tape 13 of a component type that does not cause a problem due to static electricity, and the processing load required for managing the component supply tape 13 can be reduced accordingly.
以上説明した本実施例のテープフィーダ12の部品供給テープ13の管理は、部品実装機10の制御装置31(又はホストコンピュータ41)によって図3及び図4のテープフィーダ管理プログラムに従って次のように実行される。本プログラムが起動されると、まず、ステップ101で、作業者が生産スタートボタン39(図2参照)が押すまで待機する。その後、生産スタートボタン39が押された時点で、ステップ102に進み、生産を開始する。これにより、回路基板を部品実装機10に搬入して、テープフィーダ12で部品供給テープ13の先端側からカバーテープ15を剥離して該部品供給テープ13内の電子部品を露出させながら該部品供給テープ13を部品吸着位置へ送り、該部品吸着位置の手前で部品供給テープ13の上面からカバーテープ15を剥離させてキャリアテープ16内の電子部品を露出させ、該部品吸着位置で該キャリアテープ16内の電子部品を部品実装機10の吸着ノズルで吸着して回路基板に実装する。
The management of the component supply tape 13 of the tape feeder 12 of the present embodiment described above is executed as follows according to the tape feeder management program of FIGS. 3 and 4 by the control device 31 (or host computer 41) of the component mounter 10. Is done. When this program is started, first, in step 101, the operator waits until the production start button 39 (see FIG. 2) is pressed. Thereafter, when the production start button 39 is pressed, the process proceeds to step 102 to start production. As a result, the circuit board is carried into the component mounting machine 10, the cover tape 15 is peeled off from the front end side of the component supply tape 13 by the tape feeder 12, and the electronic component in the component supply tape 13 is exposed to supply the component. The tape 13 is sent to the component suction position, and the cover tape 15 is peeled off from the upper surface of the component supply tape 13 before the component suction position to expose the electronic components in the carrier tape 16, and the carrier tape 16 is exposed at the component suction position. The electronic component is sucked by the suction nozzle of the component mounting machine 10 and mounted on the circuit board.
この後、ステップ103に進み、生産停止又は1枚生産完了(基板払出し)になるまで待機する。その後、生産停止又は1枚生産完了(基板払出し)になった時点で、ステップ104に進み、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12が存在するか否かを判定する。ここで、管理対象となる部品種の部品供給テープ13は、部品供給テープ13からカバーテープ15を剥離する際に発生する静電気による不具合が発生する可能性のある部品種の部品供給テープ13である。従って、上記ステップ104で、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12が存在しないと判定されれば、カバーテープ15を剥離する際に発生する静電気による不具合が発生しないと判断して、上記ステップ103に戻り、次の生産停止又は1枚生産完了(基板払出し)になるまで待機する。
After this, the process proceeds to step 103 and waits until the production is stopped or one piece production is completed (substrate delivery). Thereafter, when the production is stopped or the production of one sheet is completed (substrate delivery), the process proceeds to step 104 to determine whether there is a tape feeder 12 to which the component supply tape 13 of the component type to be managed exists. . Here, the component supply tape 13 of the component type to be managed is a component supply tape 13 of a component type that may cause a malfunction due to static electricity that occurs when the cover tape 15 is peeled from the component supply tape 13. . Therefore, if it is determined in step 104 that there is no tape feeder 12 to which the component supply tape 13 of the component type to be managed exists, there is no problem due to static electricity that occurs when the cover tape 15 is peeled off. After the determination, the process returns to step 103 and waits until the next production is stopped or one sheet production is completed (substrate delivery).
これに対し、上記ステップ104で、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12が存在すると判定されれば、ステップ105に進み、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12毎に、停止状態で待機するフィーダ停止時間を計測する。そして、次のステップ106で、テープフィーダ12の本体側の部分(カバーテープ15の剥離位置付近)が存在する部品実装機10の内側の空気の湿度を湿度センサ22で検出した後、ステップ107に進み、湿度センサ22で検出した湿度が所定湿度以下であるか否かを判定する。ここで、「所定湿度」は、カバーテープ15を剥離する際に発生する静電気による不具合が発生しない湿度範囲の下限値に相当し、予め決められた一定値(固定値)としても良いし、部品供給テープ13の材質や部品種等によって変化させるようにしても良い。部品供給テープ13の材質や部品種等によって、静電気による不具合の発生率が変化するためである。
On the other hand, if it is determined in step 104 that there is a tape feeder 12 to which the component supply tape 13 of the component type to be managed exists, the process proceeds to step 105 and the component supply tape 13 of the component type to be managed is obtained. For each tape feeder 12 to which is attached, the feeder stop time for waiting in a stopped state is measured. Then, in the next step 106, the humidity sensor 22 detects the humidity of the air inside the component mounting machine 10 where the main body side portion of the tape feeder 12 (near the peeling position of the cover tape 15) is present. Then, it is determined whether or not the humidity detected by the humidity sensor 22 is equal to or lower than a predetermined humidity. Here, the “predetermined humidity” corresponds to a lower limit value of a humidity range in which trouble due to static electricity that occurs when the cover tape 15 is peeled off, and may be a predetermined constant value (fixed value) or a component. You may make it change with the material of the supply tape 13, a component kind, etc. FIG. This is because the rate of occurrence of defects due to static electricity changes depending on the material, component type, and the like of the component supply tape 13.
上記ステップ107で、検出した湿度が所定湿度以下ではないと判定された場合は、静電気による不具合が発生しないと判断して、ステップ109に進み、全てのテープフィーダ12に装着されている部品供給テープ13の使用を許可して生産を継続し、上記ステップ103に戻り、次の生産停止又は1枚生産完了(基板払出し)になるまで待機する。
If it is determined in step 107 that the detected humidity is not equal to or lower than the predetermined humidity, it is determined that no trouble is caused by static electricity, and the process proceeds to step 109, where the component supply tape mounted on all the tape feeders 12 13 is permitted and the production is continued, and the process returns to the above-described step 103 and waits until the next production is stopped or the one-sheet production is completed (substrate delivery).
これに対し、上記ステップ107で、検出した湿度が所定湿度以下であると判定された場合は、ステップ108に進み、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12の中に、フィーダ停止時間が所定時間以上となったテープフィーダ12が存在するか否かを判定する。ここで、「所定時間」は、カバーテープ15を剥離する際に発生する静電気による不具合が発生しやすいフィーダ停止時間の最小値に相当し、予め決められた一定値(固定値)としても良いし、部品供給テープ13の材質や部品種等によって変化させるようにしても良い。部品供給テープ13の材質や部品種等によって、静電気による不具合の発生率が変化するためである。
On the other hand, if it is determined in step 107 that the detected humidity is equal to or lower than the predetermined humidity, the process proceeds to step 108, and the tape feeder 12 in which the component supply tape 13 of the component type to be managed is mounted. Then, it is determined whether or not there is a tape feeder 12 whose feeder stop time is equal to or longer than a predetermined time. Here, the “predetermined time” corresponds to the minimum value of the feeder stop time at which trouble due to static electricity that occurs when the cover tape 15 is peeled off, and may be a predetermined constant value (fixed value). The material may be changed depending on the material of the component supply tape 13 or the component type. This is because the rate of occurrence of defects due to static electricity changes depending on the material, component type, and the like of the component supply tape 13.
上記ステップ108で、フィーダ停止時間が所定時間以上となったテープフィーダ12が存在しないと判定された場合は、静電気による不具合が発生しないと判断して、ステップ109に進み、全てのテープフィーダ12に装着されている部品供給テープ13の使用を許可して生産を継続し、上記ステップ103に戻り、次の生産停止又は1枚生産完了(基板払出し)になるまで待機する。
If it is determined in step 108 that there is no tape feeder 12 for which the feeder stop time has reached a predetermined time or more, it is determined that there is no problem due to static electricity, and the process proceeds to step 109, where all the tape feeders 12 are set. Production is continued by permitting the use of the mounted component supply tape 13, and the process returns to step 103, and waits until the next production is stopped or one sheet production is completed (substrate delivery).
これに対し、上記ステップ108で、フィーダ停止時間が所定時間以上となったテープフィーダ12が存在すると判定された場合は、静電気による不具合が発生しやすい状態になっていると判断して、図4のステップ110に進み、フィーダ停止時間が所定時間以上となったテープフィーダ12に装着されている部品供給テープ13の使用を禁止し、次のステップ11で、フィーダ停止時間が所定時間以上となったテープフィーダ12から電子部品を吸着ノズルに吸着する動作を停止して、静電気に起因する部品吸着不良を未然に防止する。
On the other hand, if it is determined in step 108 that there is a tape feeder 12 whose feeder stop time is equal to or longer than the predetermined time, it is determined that a problem due to static electricity is likely to occur, and FIG. In step 110, the use of the component supply tape 13 mounted on the tape feeder 12 whose feeder stop time has reached a predetermined time or more is prohibited. In the next step 11, the feeder stop time has become a predetermined time or longer. The operation of sucking the electronic component from the tape feeder 12 to the suction nozzle is stopped to prevent a component suction failure caused by static electricity.
この後、ステップ112に進み、部品実装機10の表示装置33やホストコンピュータ41の表示装置等による警告表示や音声によって、静電気による不具合が発生しやすい状態になっているテープフィーダ12の部品供給テープ13が存在することを作業者に警告して、当該部品供給テープ13を交換するように促す。その後、ステップ113に進み、作業者が当該部品供給テープ13を交換するまで待機する。
Thereafter, the process proceeds to step 112, where the component supply tape of the tape feeder 12 is in a state in which a malfunction due to static electricity is likely to occur due to a warning display or sound from the display device 33 of the component mounter 10 or the display device of the host computer 41. The operator is warned that 13 is present and urged to replace the component supply tape 13. Thereafter, the process proceeds to step 113 and waits until the operator replaces the component supply tape 13.
その後、当該部品供給テープ13が交換された時点で、ステップ114に進み、交換された部品供給テープ13のリール14が交換前と同じであるか否か(つまり作業者が一旦取り外した部品供給テープ13を誤って再装着してしまったか否か)を判定し、その結果、交換された部品供給テープ13のリール14が交換前と同じであると判定されれば、ステップ116に進み、部品実装機10の表示装置33やホストコンピュータ41の表示装置等にエラー表示して、作業者に当該部品供給テープ13を再交換するように促す。その後は、上記ステップ113に戻り、上述した処理を再実行する。
Thereafter, when the component supply tape 13 is replaced, the process proceeds to step 114, and whether or not the reel 14 of the replaced component supply tape 13 is the same as before replacement (that is, the component supply tape once removed by the operator). As a result, if it is determined that the reel 14 of the replaced component supply tape 13 is the same as that before the replacement, the process proceeds to step 116 to mount the component. An error is displayed on the display device 33 of the machine 10, the display device of the host computer 41, etc., and the operator is urged to replace the component supply tape 13 again. Thereafter, the process returns to step 113, and the above-described processing is re-executed.
これに対し、上記ステップ114で、交換された部品供給テープ13のリール14が交換前と同じではないと判定されれば、ステップ115に進み、生産を再開する。以後、図3のステップ103以降の処理を再実行する。
On the other hand, if it is determined in step 114 that the reel 14 of the replaced component supply tape 13 is not the same as that before the replacement, the process proceeds to step 115 to resume production. Thereafter, the processing after step 103 in FIG. 3 is re-executed.
以上説明した本実施例では、テープフィーダ12が停止状態で待機するフィーダ停止時間を計測すると共に、テープフィーダ12が存在する空気の湿度を検出し、フィーダ停止時間と湿度に基づいてテープフィーダ12に装着されている部品供給テープ13の使用の許可/禁止を管理するようにしているため、部品供給テープ13のカバーテープ15が剥離位置付近で乾燥状態の空気に晒される時間と空気の湿度の両方を考慮して、部品供給テープ15からカバーテープ15を剥離する際に静電気による不具合が発生しやすい状態になっているか否かを監視して、静電気による不具合が発生しやすい状態になったときに部品供給テープ13の使用を禁止することが可能となり、部品供給テープ13が乾燥状態の空気に晒される時間が長くなることによる不具合を効果的に防止できる。
In the present embodiment described above, the feeder stop time during which the tape feeder 12 is stopped is measured, the humidity of the air in which the tape feeder 12 is present is detected, and the tape feeder 12 is determined based on the feeder stop time and humidity. Since the permission / prohibition of use of the mounted component supply tape 13 is managed, both the time during which the cover tape 15 of the component supply tape 13 is exposed to dry air near the peeling position and the humidity of the air In consideration of the above, when the cover tape 15 is peeled from the component supply tape 15, it is monitored whether or not the trouble due to static electricity is likely to occur, and when the trouble due to static electricity is likely to occur. The use of the component supply tape 13 can be prohibited, and the time during which the component supply tape 13 is exposed to dry air is increased. It can effectively prevent a problem due to the fact.
尚、本実施例では、計測したフィーダ停止時間が所定時間以上で且つ湿度センサ22で検出した湿度が所定湿度以下となったときに、テープフィーダ12に装着されている部品供給テープ13の使用を禁止するようにしたが、本発明は、これに限定されず、計測したフィーダ停止時間が湿度センサ22で検出した湿度に応じて設定した所定時間以上となったときに、テープフィーダ12に装着されている部品供給テープ13の使用を禁止するようにしても良い。この場合、空気の湿度が低いほど(つまり空気が乾燥するほど)、部品供給テープ13からカバーテープ15を剥離する際に静電気が発生しやすくなるため、湿度センサ22で検出した湿度が低いほど、部品供給テープ13の使用を禁止するまでのフィーダ停止時間(所定時間)を短い時間に設定するようにすれば良い。
In this embodiment, when the measured feeder stop time is equal to or longer than a predetermined time and the humidity detected by the humidity sensor 22 is equal to or lower than the predetermined humidity, the component supply tape 13 mounted on the tape feeder 12 is used. However, the present invention is not limited to this, and is mounted on the tape feeder 12 when the measured feeder stop time exceeds a predetermined time set according to the humidity detected by the humidity sensor 22. The use of the component supply tape 13 may be prohibited. In this case, static electricity is more likely to occur when the cover tape 15 is peeled from the component supply tape 13 as the humidity of the air is lower (that is, the air is dried). The feeder stop time (predetermined time) until the use of the component supply tape 13 is prohibited may be set to a short time.
また、本実施例では、部品実装機10の密閉度が比較的高く、部品実装機10の内側と外側の湿度の差が比較的大きいことを考慮して、部品実装機10の内側に湿度センサ22を設置して、テープフィーダ12の本体側の部分(カバーテープ15の剥離位置付近)が存在する部品実装機10の内側の空気の湿度を検出するようにしたので、静電気による不具合が発生するカバーテープ15の剥離位置付近の空気の湿度を精度良く検出することができ、静電気による不具合が発生しやすい状態であるか否かを精度良く監視することができる。但し、部品実装機10の内側と外側の湿度の差が比較的小さい構成となっている場合は、部品実装機10の外側に湿度センサ22を設置して、部品実装機10の外側の空気の湿度を検出するようにしても良い。
Further, in the present embodiment, considering that the sealing degree of the component mounting machine 10 is relatively high and the difference in humidity between the inside and outside of the component mounting machine 10 is relatively large, a humidity sensor is provided inside the component mounting machine 10. 22 is installed to detect the humidity of the air inside the component mounter 10 where the main body side portion of the tape feeder 12 (near the peeling position of the cover tape 15) is present, which causes a problem due to static electricity. The humidity of the air in the vicinity of the peeling position of the cover tape 15 can be detected with high accuracy, and it can be accurately monitored whether or not a malfunction due to static electricity is likely to occur. However, when the difference in humidity between the inside and outside of the component mounter 10 is relatively small, a humidity sensor 22 is installed outside the component mounter 10 so that the air outside the component mounter 10 is removed. Humidity may be detected.
また、本実施例では、テープフィーダ12に装着可能な複数の部品種の部品供給テープ13のうち、静電気による不具合が発生する可能性のある部品種の部品供給テープ13のみを管理対象とし、管理対象となる部品種の部品供給テープ13を装着したテープフィーダ12についてのみ当該部品供給テープ13の使用の許可/禁止を管理するようにしたが、部品実装機10にセットした全てのテープフィーダ12について部品供給テープ13の使用の許可/禁止を管理するようにしても良い。
Further, in this embodiment, among the component supply tapes 13 of a plurality of component types that can be mounted on the tape feeder 12, only the component supply tape 13 of a component type that may cause a failure due to static electricity is managed and managed. Although the permission / prohibition of use of the component supply tape 13 is managed only for the tape feeder 12 to which the component supply tape 13 of the target component type is mounted, all the tape feeders 12 set in the component mounter 10 are managed. The permission / prohibition of use of the component supply tape 13 may be managed.
また、本実施例では、部品実装機10にセットした複数のテープフィーダ12のうち、フィーダ停止時間と湿度に基づいて部品供給テープ13の使用の禁止と判定されたテープフィーダ12についてのみ部品吸着を停止するようにしたが、部品実装機10にセットした全てのテープフィーダ12の部品吸着を停止するようにしても良く、また、部品実装機10の両サイドにテープフィーダ12をセットする構成のものでは、部品供給テープ13の使用の禁止と判定されたテープフィーダ12がセットされたサイドのテープフィーダ12の部品吸着を停止するようにしても良い。また、生産ラインに複数台の部品実装機10を配列した構成のものでは、いずれかの部品実装機10において、フィーダ停止時間と湿度に基づいて部品供給テープ13の使用の禁止と判定された場合に、生産ラインの全ての部品実装機10を停止させるようにしても良い。
In the present embodiment, among the plurality of tape feeders 12 set in the component mounting machine 10, the component suction is performed only for the tape feeder 12 that is determined to be prohibited from using the component supply tape 13 based on the feeder stop time and humidity. Although it stopped, you may make it stop component adsorption | suction of all the tape feeders 12 set to the component mounting machine 10, and the structure which sets the tape feeder 12 to the both sides of the component mounting machine 10 Then, the component suction of the side tape feeder 12 on which the tape feeder 12 determined to be prohibited from using the component supply tape 13 is set may be stopped. Further, in a configuration in which a plurality of component mounting machines 10 are arranged on the production line, when any of the component mounting machines 10 is determined to be prohibited from using the component supply tape 13 based on the feeder stop time and humidity. In addition, all the component mounting machines 10 in the production line may be stopped.
その他、本発明は、部品実装機10の構成やテープフィーダ12の構成を適宜変更しても良い等、要旨を逸脱しない範囲内で種々変更して実施できることは言うまでもない。
In addition, it goes without saying that the present invention can be implemented with various modifications within a range not departing from the gist, such as appropriately changing the configuration of the component mounter 10 and the configuration of the tape feeder 12.
