【発明の属する技術分野】
本発明は、電子部品を搬送しながら所定部分をレーザ光にて切除するトリミング加工を行うレーザトリミング装置に関し、特にトリミング加工に伴って発生する粉塵の影響を最小限に抑えることができるものに関する。
【0002】
【従来の技術】
レーザトリミング装置は、レーザ光のパワーを利用して電子部品の部分切除や部分除去等の加工(以下、「トリミング加工」と称する。)を行い、部品の特性を調整するものである。例えば、チップ状電子部品の調整、すなわち高周波用コイルのインダクタンスや抵抗値の調整等は、特性を測定しながらレーザ光を用いてトリミング加工により行われる。しかしながら、レーザ光を用いたトリミング加工は、部品の組成材料の蒸発によって行われるため、蒸発気化した材料の拡散量は元の容積の数千倍以上にもなり、それが空中で冷却され凝縮して微塵化し、その粉塵が周囲に付着する。このため、近くに測定機器があると、光学系を汚して検出し難くしたり、電気接点を汚して接点不良が多々発生するため、従来は検査・測定とトリミング加工は別々の装置により行っていた。
【0003】
【発明が解決しようとする課題】
上述した従来のレーザトリミング装置においては次のような問題があった。すなわち、電子部品の特性測定とトリミング加工とを別々の装置で行っていたため、材料の蒸発による粉塵が周囲の機器に付着し、生産効率が低下するという問題と、装置を設置するために広いスペースが必要になるという問題があった。
【0004】
そこで本発明は、トリミング加工により発生する粉塵により測定精度を低下させることがなく、また生産効率の高いレーザトリミング装置を提供することを目的としている。
【0005】
【課題を解決するための手段】
上記課題を解決し目的を達成するために、本発明のレーザトリミング装置は次のように構成されている。

【0013】
【発明の実施の形態】
図1は本発明の一実施の形態に係るレーザトリミング装置10を示す平面図、図2はレーザトリミング装置10に組み込まれた吸着部22の吸着方法を示す説明図、図3はレーザトリミング装置10に組み込まれた副搬送テーブル31の要部を示す断面図である。なお、図中Wは電子部品を示しており、Waは下面、Wbは上面を示している。下面Waには電極Wcが形成されている。また、上面Wbは被吸着面であり、後述するレーザトリミング機構40によりトリミングされる。さらに、Wdは電子部品Wの側面を示している。
【0014】
レーザトリミング装置10は、電子部品Wの供給・測定・排出を行う主搬送部20と、トリミング加工を行う副搬送部30とを備えている。
【0015】
主搬送部20は、図1中矢印R方向に間欠回転する主搬送テーブル21を備えている。主搬送テーブル21の外縁部には、円周方向に沿って電子部品Wの上面Wbを吸着保持する吸着部22が設けられている。吸着部22は図2に示すように吸着ノズル22aを備え、この吸着ノズル22aは吸引装置(不図示)に接続されている。また、主搬送テーブル21の外周には、図1中左端から時計回りに、電子部品Wを供給するリニアフィーダ(電子部品供給手段)23、電子部品Wの電気的特性を測定する第1特性測定装置24、副搬送部30との間で電子部品Wを移載する移載部25、電子部品Wの電気的特性を測定する第2特性測定装置26、不良の電子部品Wを排出する排出トレイ(部品排出手段)27、電子部品WをキャリアテープCの収納凹部に収納するテーピング装置(電子部品搬出手段)28とを備えている。
【0016】
副搬送部30は、図1中矢印r方向に回転する副搬送テーブル31を備えている。副搬送テーブル31の外縁部には、円周方向に沿って電子部品Wの側面Wdを把持する把持機構32が設けられている。把持機構32は、図3に示すように、副搬送テーブル31に固定して取り付けられた固定把持片33と、副搬送テーブル31に固定部34を介して回転軸S回りに回動可能に取り付けられた可動把持片35と、この可動把持片35の作用端35aを図3中矢印α方向に付勢するスプリング36と、可動把持片35の駆動端35bを押し上げる押上機構37とを備えている。
【0017】
また、副搬送テーブル31の外周には、電子部品Wの上面Wbを切除するレーザトリミング機構40及び吸塵装置41が配置されている。
【0018】
このように構成されたレーザトリミング装置10では、次のようにして電子部品Wのトリミングを行う。すなわち、リニアフィーダ23で順次搬送されてくる電子部品Wの上面Wbを吸着部22の吸着ノズル22aにより吸着する。次に、電子部品Wは主搬送テーブル31により第1特性測定装置24まで搬送される。第1特性測定装置24では電子部品Wの電極Wcに測定端子(不図示)を接触させ、特性を測定する。測定終了後、電子部品Wは移載部25まで搬送される。
【0019】
移載部25では、副搬送部30の押上機構37が動作し、可動把持片35の作用端35aが矢印αと逆方向に移動し、固定把持片33との間に隙間が生じる。一方、電子部品Wが移載部25に到達し、この隙間に電子部品Wが位置決めされると、吸着部22による電子部品Wの吸着が停止される。続いて、押上機構37の動作が終了し、可動把持片35の作用端35aはスプリング36の付勢により固定把持片33との間に電子部品Wを挟み、把持する。
【0020】
次に、副搬送テーブル31が電子部品Wをレーザトリミング機構40まで搬送する。レーザトリミング機構40では、第1特性測定装置24によって測定された電子部品Wの特性に基づいて、所定量のトリミング加工を行う。トリミング加工によって、電子部品Wの部分切断や部分除去した組成材料は蒸発した後、冷却して微塵化するが、吸塵装置41により吸引・処理される。これにより粉塵が主搬送部20側に影響を与えることはない。
【0021】
トリミング加工終了後、副搬送テーブル31が電子部品Wを移載部25まで搬送する。押上機構37が動作し、可動把持片35の作用端35aが矢印α方向と逆方向に移動し、固定把持片33との間による電子部品Wの把持が解除される。そして、吸着部22により再度電子部品Wが吸着される。次に、電子部品Wは主搬送テーブル31により第2特性測定装置26まで搬送される。第2特性測定装置26では電子部品Wの電極Wcに測定端子(不図示)を接触させ、特性を測定する。このとき、特性が許容範囲内であれば良品とされ、許容範囲外であれば不良品となる。測定終了後、不良品と判断された電子部品Wは排出トレイ(部品排出手段)27の上方まで搬送され、吸着部22の吸着が解除される。そして、排出トレイ27内に収容される。
【0022】
一方、測定終了後、良品と判断された電子部品Wはテーピング装置28まで搬送され、キャリアテープCの収納凹部に収納される。
【0023】
上述したように本実施の形態に係るレーザトリミング装置10によれば、トリミングの際に発生する微塵化した粉塵を副搬送部30側で処理することで、主搬送部20側への粉塵の影響を最小限に抑えることができ、第1の特性測定装置24及び第2の特性測定装置26による測定に影響を与えることがない。また、検査・測定とレーザ加工とを同一の装置で行うため、生産効率を高めることができるとともに、装置を設置するスペースを小さくすることが可能である。
【0024】
なお、本発明は前記実施の形態に限定されるものではない。すなわち、上述した実施の形態では、主搬送手段や副搬送手段として回転テーブルを用いているが、コンベア等のように直線的に部品を搬送するものであってもよい。また、保持手段として吸引、把持等の方法を用いているがこれらの保持方法に限られない。この他、本発明の要旨を逸脱しない範囲で種々変形実施可能であるのは勿論である。
【0025】
【発明の効果】
本発明によれば、トリミング加工により発生した粉塵により測定精度を低下させることがなく、また生産効率が高く、装置の設置スペースを小さくすることができるレーザトリミング装置を提供することが可能となる。

It is sectional drawing which shows the principal part of the subcarrier table 31 integrated in the. In the figure, W indicates an electronic component, Wa indicates a lower surface, and Wb indicates an upper surface. An electrode Wc is formed on the lower surface Wa. The upper surface Wb is a surface to be attracted and is trimmed by a laser trimming mechanism 40 described later. Further, Wd indicates a side surface of the electronic component W.
[0014]
The laser trimming apparatus 10 includes a main transport unit 20 that supplies, measures, and discharges an electronic component W, and a sub transport unit 30 that performs trimming.
[0015]
The main transport unit 20 includes a main transport table 21 that intermittently rotates in the direction of arrow R in FIG. A suction portion 22 that sucks and holds the upper surface Wb of the electronic component W along the circumferential direction is provided on the outer edge portion of the main transport table 21. The suction unit 22 includes a suction nozzle 22a as shown in FIG. 2, and this suction nozzle 22a is connected to a suction device (not shown). Further, on the outer periphery of the main transfer table 21, a linear feeder (electronic component supply means) 23 that supplies the electronic component W clockwise from the left end in FIG. 1, and a first characteristic measurement that measures the electrical characteristics of the electronic component W. A transfer unit 25 for transferring the electronic component W between the device 24 and the sub-conveying unit 30; a second characteristic measuring device 26 for measuring the electrical characteristics of the electronic component W; and a discharge tray for discharging the defective electronic component W (Component discharge means) 27 and a taping device (electronic component carry-out means) 28 for storing the electronic component W in the storage recess of the carrier tape C are provided.
[0016]
The sub-transport unit 30 includes a sub-transport table 31 that rotates in the direction of arrow r in FIG. A gripping mechanism 32 that grips the side surface Wd of the electronic component W along the circumferential direction is provided at the outer edge portion of the sub-transport table 31. As shown in FIG. 3, the gripping mechanism 32 is fixedly attached to the sub-transport table 31 and fixedly attached to the sub-transport table 31, and is attached to the sub-transport table 31 through the fixing portion 34 so as to be rotatable around the rotation axis S. 3, a spring 36 that urges the working end 35 a of the movable gripping piece 35 in the direction of arrow α in FIG. 3, and a push-up mechanism 37 that pushes up the drive end 35 b of the movable gripping piece 35. .
[0017]
In addition, a laser trimming mechanism 40 and a dust suction device 41 for cutting the upper surface Wb of the electronic component W are disposed on the outer periphery of the sub-transport table 31.
[0018]
In the laser trimming apparatus 10 configured as described above, the electronic component W is trimmed as follows. That is, the upper surface Wb of the electronic component W sequentially conveyed by the linear feeder 23 is adsorbed by the adsorption nozzle 22a of the adsorption unit 22. Next, the electronic component W is transported to the first characteristic measuring device 24 by the main transport table 31. In the first characteristic measurement device 24, a measurement terminal (not shown) is brought into contact with the electrode Wc of the electronic component W, and the characteristic is measured. After the measurement is completed, the electronic component W is transported to the transfer unit 25.
[0019]
In the transfer unit 25, the push-up mechanism 37 of the sub-conveying unit 30 operates, the action end 35 a of the movable gripping piece 35 moves in the direction opposite to the arrow α, and a gap is generated between the fixed gripping piece 33. On the other hand, when the electronic component W reaches the transfer unit 25 and the electronic component W is positioned in the gap, the suction of the electronic component W by the suction unit 22 is stopped. Subsequently, the operation of the push-up mechanism 37 is finished, and the action end 35a of the movable gripping piece 35 holds the electronic component W between the fixed gripping piece 33 by the bias of the spring 36 and grips it.
[0020]
Next, the auxiliary conveyance table 31 conveys the electronic component W to the laser trimming mechanism 40. The laser trimming mechanism 40 performs a predetermined amount of trimming processing based on the characteristics of the electronic component W measured by the first characteristic measuring device 24. The trimming process partially evaporates and partially removes the composition material from which the electronic component W is evaporated, and then cools and pulverizes the composition material, but is sucked and processed by the dust suction device 41. Thereby, dust does not affect the main conveyance part 20 side.
[0021]
After the trimming process is completed, the sub-transport table 31 transports the electronic component W to the transfer unit 25. The push-up mechanism 37 operates, the action end 35a of the movable gripping piece 35 moves in the direction opposite to the arrow α direction, and the gripping of the electronic component W with the fixed gripping piece 33 is released. Then, the electronic component W is again adsorbed by the adsorbing unit 22. Next, the electronic component W is transported to the second characteristic measuring device 26 by the main transport table 31. In the second characteristic measuring device 26, a measurement terminal (not shown) is brought into contact with the electrode Wc of the electronic component W, and the characteristic is measured. At this time, if the characteristic is within the allowable range, the product is regarded as a non-defective product. After the measurement is completed, the electronic component W determined to be defective is conveyed to above the discharge tray (component discharge means) 27, and the suction of the suction portion 22 is released. And it is accommodated in the discharge tray 27.
[0022]
On the other hand, after completion of the measurement, the electronic component W determined to be non-defective is conveyed to the taping device 28 and stored in the storage recess of the carrier tape C.
[0023]
As described above, according to the laser trimming apparatus 10 according to the present embodiment, the influence of dust on the main transport unit 20 side is obtained by processing the fine dust generated at the time of trimming on the sub transport unit 30 side. Can be minimized, and the measurement by the first characteristic measurement device 24 and the second characteristic measurement device 26 is not affected. In addition, since inspection / measurement and laser processing are performed by the same apparatus, it is possible to increase the production efficiency and to reduce the space for installing the apparatus.
[0024]
The present invention is not limited to the above embodiment. That is, in the above-described embodiment, the rotary table is used as the main transport unit and the sub transport unit, but the part may be transported linearly such as a conveyor. Further, although a method such as suction or gripping is used as the holding means, the holding method is not limited to these methods. Of course, various modifications can be made without departing from the scope of the present invention.
