At this time, all the displacement amounts detected by the strain gauge 148 are stored in the storage device 198 in association with the time when each lead is cut and the information indicating the type of the cut lead component.
- the lead parts of the same type are parts having the same shape, the same performance, the same material, the same wire diameter, and the same color. Then, it is determined whether or not the threshold value is exceeded in all the displacement amounts detected by the strain gauge 148.
- the change in the displacement amount detected by the strain gauge 148 is confirmed.
- the load applied to the fixed blade 131 and the movable blade 138 becomes large, so that an error is likely to occur in the displacement amount detected by the strain gauge 148.

- the storage device 198 stores the time when each lead is cut in association with the information indicating the type of the lead component.
- the displacement amount of the strain gauge when the lead is cut 10 times it is the displacement amount of the strain gauge when the lead is cut 10 times in succession, for example, 3 times, and the displacement amount at the time of the second cutting.
- the storage device 198 stores the displacement amount at the time of the third cutting and the displacement amount at the time of the fourth cutting.

また、自転装置156は、概して円盤状の回転テーブル178を有している。回転テーブル178は、それの鉛直軸心を中心に回転可能にZスライダ174に支持されており、電磁モータ(図8参照)180の駆動により、回転する。そして、回転テーブル178の上に、カットアンドクリンチユニット100が、作業者が工具を用いることなくワンタッチで着脱可能に位置決めして配設されている。このような構造により、カットアンドクリンチユニット100は、X方向移動装置150、Y方向移動装置152、Z方向移動装置154によって、任意の位置に移動するとともに所定の位置に位置決めが可能であり、また、自転装置156によって、任意の角度に自転するとともに所定の角度に位置決めが可能である。これにより、カットアンドクリンチユニット100を、クランプ装置52によって保持された回路基材12の下方において、任意の位置および角度に位置決めすることが可能である。
Further, the rotation device 156 generally has a disk-shaped rotary table 178. The rotary table 178 is rotatably supported by the Z slider 174 about its vertical axis and is rotated by the drive of an electromagnetic motor (see FIG. 8) 180. Then, the cut and clinch unit 100 is positioned and arranged on the rotary table 178 so that the operator can attach and detach it with one touch without using a tool. With such a structure, the cut-and-clinch unit 100 can be moved to an arbitrary position and positioned at a predetermined position by the X-direction moving device 150, the Y-direction moving device 152, and the Z-direction moving device 154. With the rotation device 156, it is possible to rotate at an arbitrary angle and position it at a predetermined angle. This makes it possible to position the cut and clinch unit 100 at any position and angle below the circuit substrate 12 held by the clamp device 52.
制御装置36は、図8に示すように、コントローラ190、複数の駆動回路192、画像処理装置196を備えている。複数の駆動回路192は、上記搬送装置50、クランプ装置52、作業ヘッド60,62、作業ヘッド移動装置64、トレイ型部品供給装置78、フィーダ型部品供給装置80、ばら部品供給装置32、電磁モータ118,128,164,170,176,180に接続されている。コントローラ190は、CPU,ROM,RAM等を備え、コンピュータを主体とするものであり、複数の駆動回路192に接続されている。これにより、基材搬送保持装置22、部品装着装置24等の作動が、コントローラ190によって制御される。また、コントローラ190は、画像処理装置196に接続されている。画像処理装置196は、マークカメラ26およびパーツカメラ28によって得られた画像データを処理するものであり、コントローラ190は、それら画像データから各種情報を取得する。
As shown in FIG. 8, the control device 36 includes a controller 190, a plurality of drive circuits 192, and an image processing device 196. The plurality of drive circuits 192 include the transfer device 50, the clamp device 52, the work heads 60 and 62, the work head moving device 64, the tray type parts supply device 78, the feeder type parts supply device 80, the loose parts supply device 32, and the electromagnetic motor. It is connected to 118, 128, 164, 170, 176, 180. The controller 190 includes a CPU, ROM, RAM, and the like, and is mainly a computer, and is connected to a plurality of drive circuits 192. As a result, the operation of the base material transfer holding device 22, the component mounting device 24, and the like is controlled by the controller 190. Further, the controller 190 is connected to the image processing device 196. The image processing device 196 processes the image data obtained by the mark camera 26 and the parts camera 28, and the controller 190 acquires various information from the image data.
また、制御装置36は記憶装置198を有している。記憶装置198は、コントローラ190に接続されており、コントローラ190からの指令に従って、各種情報を記憶する。また、制御装置36は、表示パネル199にも接続されている。表示パネル199は、図1に示すように、ばら部品供給装置32の作業者側に配設されており、制御装置36からの指令に従って、任意の画面を表示する。さらに、コントローラ190は、歪ゲージ148にも接続されている。歪ゲージ148は、上述したように、抵抗体の変形に伴う電気抵抗に基づいて変位量を検出する。このため、コントローラ190は、歪ゲージ148により検出された変位量を取得する。
Further, the control device 36 has a storage device 198. The storage device 198 is connected to the controller 190 and stores various information according to a command from the controller 190. The control device 36 is also connected to the display panel 199. As shown in FIG. 1, the display panel 199 is arranged on the operator side of the loose parts supply device 32, and displays an arbitrary screen according to a command from the control device 36. Further, the controller 190 is also connected to the strain gauge 148. As described above, the strain gauge 148 detects the displacement amount based on the electric resistance accompanying the deformation of the resistor. Therefore, the controller 190 acquires the displacement amount detected by the strain gauge 148.
なお、歪ゲージ148は、コネクタを介してコントローラ190に接続されている。詳しくは、図9に示すように、カットアンドクリンチユニット100の1対のスライド体112各々の隣の位置には、コネクタ200が可動本体140に固定的に配設されている。また、歪ゲージ148は、上述したように、スライド体112を構成する可動体122の可動交換体142に配設されている。そして、その歪ゲージ148には、出力線202の一端部が接続されており、その出力線202の他端部が、コネクタ200に接続されている。また、コネクタ200には、可動交換体142が任意の水平方向および垂直方向の位置に移動できるように、コントローラ190に通じる入力線204の一端部が接続されている。このように、歪ゲージ148は、コネクタ200を介してコントローラ190に接続されている。
The strain gauge 148 is connected to the controller 190 via a connector. Specifically, as shown in FIG. 9, a connector 200 is fixedly arranged on the movable main body 140 at a position next to each of the pair of slide bodies 112 of the cut and clinch unit 100. Further, as described above, the strain gauge 148 is arranged on the movable exchange body 142 of the movable body 122 constituting the slide body 112. One end of the output line 202 is connected to the strain gauge 148, and the other end of the output line 202 is connected to the connector 200. Further, one end of an input line 204 leading to the controller 190 is connected to the connector 200 so that the movable exchange 142 can move to arbitrary horizontal and vertical positions. In this way, the strain gauge 148 is connected to the controller 190 via the connector 200.
部品実装機10では、上述した構成によって、基材搬送保持装置22に保持された回路基材12に対して部品の装着作業が行われる。部品実装機10では、種々の部品を回路基材12に装着することが可能であるが、リード部品106を回路基材12に装着する場合について、以下に説明する。
In the component mounting machine 10, components are mounted on the circuit substrate 12 held by the substrate transfer holding device 22 according to the above-described configuration. In the component mounting machine 10, various components can be mounted on the circuit base material 12, but a case where the lead component 106 is mounted on the circuit base material 12 will be described below.
具体的には、回路基材12が、基材搬送保持装置22の搬送装置50によって作業位置まで搬送され、その位置において、クランプ装置52によって固定的に保持される。次に、マークカメラ26が、回路基材12の上方に移動し、回路基材12を撮像する。これにより、回路基材12の保持位置等に関する情報が得られる。また、部品供給装置30若しくは、ばら部品供給装置32が、所定の供給位置において、リード部品106を作業ヘッド60,62に供給する。そして、作業ヘッド60,62の何れかが、部品の供給位置の上方に移動し、吸着ノズル66によって、リード部品106の部品本体(図10参照)200を吸着保持する。
Specifically, the circuit base material 12 is transported to a working position by the transport device 50 of the base material transport and holding device 22, and is fixedly held by the clamp device 52 at that position. Next, the mark camera 26 moves above the circuit base material 12 and takes an image of the circuit base material 12. As a result, information regarding the holding position of the circuit base material 12 and the like can be obtained. Further, the component supply device 30 or the loose component supply device 32 supplies the lead component 106 to the work heads 60 and 62 at a predetermined supply position. Then, one of the work heads 60 and 62 moves above the supply position of the component, and the component body (see FIG. 10) 200 of the lead component 106 is suction-held by the suction nozzle 66.
続いて、リード部品106を保持した作業ヘッド60,62が、パーツカメラ28の上方に移動し、パーツカメラ28によって、吸着ノズル66に保持されたリード部品106が撮像される。これにより、部品の保持位置等に関する情報が得られる。続いて、リード部品106を保持した作業ヘッド60,62が、回路基材12の上方に移動し、回路基材12の保持位置の誤差,部品の保持位置の誤差等を補正する。そして、吸着ノズル66により吸着保持されたリード部品106のリード108が、回路基材12に形成された貫通穴104に挿入される。この際、回路基材12の下方には、カットアンドクリンチユニット100が移動している。
Subsequently, the work heads 60 and 62 holding the lead component 106 move above the parts camera 28, and the lead component 106 held by the suction nozzle 66 is imaged by the parts camera 28. As a result, information regarding the holding position of the component and the like can be obtained. Subsequently, the work heads 60 and 62 holding the lead component 106 move above the circuit base material 12, and correct an error in the holding position of the circuit base material 12, an error in the holding position of the component, and the like. Then, the lead 108 of the lead component 106 sucked and held by the suction nozzle 66 is inserted into the through hole 104 formed in the circuit base material 12. At this time, the cut and clinch unit 100 moves below the circuit base material 12.
具体的には、カットアンドクリンチユニット100において、1対のスライド体112の第2挿入穴136の間の距離が、回路基材12に形成された2つの貫通穴104の間の距離と同じとなるように、1対のスライド体112の間の距離が、電磁モータ118の作動により移動して位置決めされる。また、回路基材12の2つの貫通穴104の並ぶ方向と、1対のスライド体112の2つの第2挿入穴136の並ぶ方向とが一致するように、自転装置156が作動して位置決めされる。
Specifically, in the cut and clinch unit 100, the distance between the second insertion holes 136 of the pair of slide bodies 112 is the same as the distance between the two through holes 104 formed in the circuit base material 12. As such, the distance between the pair of slide bodies 112 is moved and positioned by the operation of the electromagnetic motor 118. Further, the rotation device 156 is operated and positioned so that the line-up direction of the two through holes 104 of the circuit base material 12 and the line-up direction of the two second insertion holes 136 of the pair of slide bodies 112 coincide with each other. Ru.
そして、X方向移動装置150及びY方向移動装置152の作動により、第2挿入穴136のXY方向での座標と、回路基材12の貫通穴104のXY方向での座標とが一致するように、カットアンドクリンチユニット100が移動して位置決めされる。これにより、カットアンドクリンチユニット100が、XY方向に沿って移動することで、スライド体112の第2挿入穴136と、回路基材12の貫通穴104とが上下方向に重なった状態に位置決めされる。
Then, by operating the X-direction moving device 150 and the Y-direction moving device 152, the coordinates of the second insertion hole 136 in the XY direction and the coordinates of the through hole 104 of the circuit base material 12 in the XY direction match. , The cut and clinch unit 100 is moved and positioned. As a result, the cut and clinch unit 100 moves along the XY direction, so that the second insertion hole 136 of the slide body 112 and the through hole 104 of the circuit base material 12 are positioned so as to overlap each other in the vertical direction. Ru.
次に、カットアンドクリンチユニット100は、Z方向移動装置154の作動により、可動体122の上面が回路基材12の下面に接触、若しくは、回路基材12の下面に近接する僅か下方に位置するように、上昇して位置決めされる。このように、X方向移動装置150,Y方向移動装置152,Z方向移動装置154,自転装置156の作動が制御されることで、スライド体112の第2挿入穴136と、回路基材12の貫通穴104とが重なった状態で、カットアンドクリンチユニット100が回路基材12の下方に位置決めされる。
Next, the cut-and-clinch unit 100 is located so that the upper surface of the movable body 122 comes into contact with the lower surface of the circuit base material 12 or is located slightly below the lower surface of the circuit base material 12 due to the operation of the Z-direction moving device 154. Ascended and positioned as such. By controlling the operation of the X-direction moving device 150, the Y-direction moving device 152, the Z-direction moving device 154, and the rotating device 156 in this way, the second insertion hole 136 of the slide body 112 and the circuit base material 12 The cut-and-clinch unit 100 is positioned below the circuit substrate 12 in a state where it overlaps with the through hole 104.
そして、吸着ノズル66により吸着保持されたリード部品106のリード108が、回路基材12の貫通穴104に挿入されると、そのリード108の先端部は、図10に示すように、カットアンドクリンチユニット100の可動体122の第2挿入穴136を経て、固定体120の第1挿入穴130に挿入される。次に、リード108の先端部が、固定体120の第1挿入穴130に挿入されると、1対の可動体122が電磁モータ128の作動により離間する方向にスライドする。これにより、リード108が、図11に示すように、第1挿入穴130の固定刃131と第2挿入穴136の可動刃138とによって切断される。そして、リード108の切断により分離された先端部は、第1挿入穴130の内部において落下し、廃棄ボックス132に収容される。
Then, when the lead 108 of the lead component 106 sucked and held by the suction nozzle 66 is inserted into the through hole 104 of the circuit base material 12, the tip portion of the lead 108 is cut and clinched as shown in FIG. It is inserted into the first insertion hole 130 of the fixed body 120 through the second insertion hole 136 of the movable body 122 of the unit 100. Next, when the tip of the lead 108 is inserted into the first insertion hole 130 of the fixed body 120, the pair of movable bodies 122 slide in a direction away from each other by the operation of the electromagnetic motor 128. As a result, the lead 108 is cut by the fixed blade 131 of the first insertion hole 130 and the movable blade 138 of the second insertion hole 136, as shown in FIG. Then, the tip portion separated by cutting the lead 108 falls inside the first insertion hole 130 and is housed in the waste box 132.
また、1対の可動体122は、リード108を切断した後も、さらに離間する方向にスライドする。このため、先端が切断されたリード108は、可動体122のスライドに伴って、第2挿入穴136の内周のテーパ面に沿って屈曲し、さらに、可動体122がスライドすることで、リード108が可動交換体142に設けられたガイド溝139に沿って屈曲する。これにより、先端が切断された1対のリード108は、互いに離間する方向に屈曲し、リード108の貫通穴104からの抜けが防止された状態で、リード部品106が回路基材12に装着される。
Further, the pair of movable bodies 122 slide in a direction further separated even after the lead 108 is cut. Therefore, the lead 108 whose tip is cut bends along the tapered surface of the inner circumference of the second insertion hole 136 as the movable body 122 slides, and the movable body 122 slides to lead the lead 108. 108 bends along a guide groove 139 provided in the movable exchanger 142. As a result, the pair of leads 108 whose tips are cut are bent in a direction away from each other, and the lead component 106 is mounted on the circuit base material 12 in a state where the leads 108 are prevented from coming off from the through hole 104. To.
このように、カットアンドクリンチユニット100において、固定刃131と可動刃138とによりリード部品106のリード108が切断され、屈曲されることで、リード部品106が回路基材12に装着される。ただし、固定刃131及び可動刃138は消耗品であるため、リード108の切断に伴って切れ味が低下したり欠けが生じたりすると、交換する必要がある。このため、従来は、作業者がリードの切断面を確認し、切断面が滑らかでない場合に、作業者が、固定刃131及び可動刃138の切れ味が低下していると判断し、固定刃131及び可動刃138の交換を行っていた。しかしながら、切断面が滑らかでない場合、つまり、切断面が荒れている場合には、リード108が滑らかに切断されずに、そのような場合には、リード108を適切に切断することができずに、部品実装機10の稼働を止めてしまう虞がある。
In this way, in the cut and clinch unit 100, the lead 108 of the lead component 106 is cut and bent by the fixed blade 131 and the movable blade 138, so that the lead component 106 is mounted on the circuit base material 12. However, since the fixed blade 131 and the movable blade 138 are consumables, they need to be replaced if the sharpness is lowered or chipped due to the cutting of the lead 108. For this reason, conventionally, the operator confirms the cut surface of the lead, and when the cut surface is not smooth, the operator determines that the sharpness of the fixed blade 131 and the movable blade 138 is deteriorated, and the fixed blade 131. And the movable blade 138 was replaced. However, if the cut surface is not smooth, that is, if the cut surface is rough, the lead 108 will not be cut smoothly, and in such a case, the lead 108 cannot be cut properly. , There is a risk that the operation of the component mounting machine 10 will be stopped.
また、カットアンドクリンチユニット100によるリード108の切断回数をカウントしておいて、カウントされた切断回数が予め設定された閾回数を超えた場合に、固定刃131及び可動刃138の切れ味が低下すると想定し、固定刃131及び可動刃138の交換を行うことも可能である。しかしながら、リード108の切断回数が閾回数を超えた場合であっても、固定刃131及び可動刃138の切れ味が低下していない場合がある。このような場合には、まだ使用することのできる固定刃131及び可動刃138、つまり、まだ切れ味が低下していない固定刃131及び可動刃138を交換しなければならず、無駄が生じる。一方、リード108の切断回数が閾回数を超える前に、固定刃131及び可動刃138の切れ味が低下する場合もある。このような場合には、既に切れ味が低下している固定刃131及び可動刃138によりリードの切断が実行されるために、適切にリードを切断できない虞がある。このように、リードの切断回数を利用して固定刃131及び可動刃138の適切な交換時期を推定することができない。
Further, when the number of cuts of the lead 108 by the cut and clinch unit 100 is counted and the counted number of cuts exceeds a preset threshold number, the sharpness of the fixed blade 131 and the movable blade 138 is reduced. Assuming, it is also possible to replace the fixed blade 131 and the movable blade 138. However, even when the number of cuts of the lead 108 exceeds the threshold number, the sharpness of the fixed blade 131 and the movable blade 138 may not be deteriorated. In such a case, the fixed blade 131 and the movable blade 138 that can still be used, that is, the fixed blade 131 and the movable blade 138 whose sharpness has not been deteriorated must be replaced, which is wasteful. On the other hand, the sharpness of the fixed blade 131 and the movable blade 138 may decrease before the number of cuts of the lead 108 exceeds the threshold number. In such a case, since the lead is cut by the fixed blade 131 and the movable blade 138 whose sharpness has already deteriorated, there is a possibility that the lead cannot be cut properly. As described above, it is not possible to estimate an appropriate replacement time of the fixed blade 131 and the movable blade 138 by using the number of times the lead is cut.
このようなことに鑑みて、カットアンドクリンチユニット100では、歪ゲージ148により検出された変位量を利用して、固定刃131及び可動刃138の交換時期の推定が行われる。つまり、歪ゲージ148により検出された変位量は、その歪ゲージ148が配設されている可動体122の変位量とみなすことができる。そして、可動体122の可動刃138と固定体120の固定刃131とによりリードが切断される際に、可動体122が僅かに撓むことで変形する。このため、固定刃131及び可動刃138の切れ味が良い場合には、リード108が固定刃131及び可動刃138により滑らかに切断されるため、可動体122の変位量、つまり、歪ゲージ148の変位量は小さい。一方、固定刃131及び可動刃138の切れ味が悪い場合には、リード切断時に固定刃131及び可動刃138にかかる負荷が大きくなり、可動体122の変位量、つまり、歪ゲージ148の変位量は大きくなる。そこで、歪ゲージ148により検出された変位量が、予め設定された閾値を超える場合には、固定刃131及び可動刃138の交換を促す画面が表示パネル199に表示される。
In view of this, in the cut and clinch unit 100, the replacement time of the fixed blade 131 and the movable blade 138 is estimated by using the displacement amount detected by the strain gauge 148. That is, the displacement amount detected by the strain gauge 148 can be regarded as the displacement amount of the movable body 122 in which the strain gauge 148 is arranged. Then, when the lead is cut by the movable blade 138 of the movable body 122 and the fixed blade 131 of the fixed body 120, the movable body 122 is slightly bent and deformed. Therefore, when the fixed blade 131 and the movable blade 138 have good sharpness, the lead 108 is smoothly cut by the fixed blade 131 and the movable blade 138, so that the displacement amount of the movable body 122, that is, the displacement of the strain gauge 148 The amount is small. On the other hand, when the fixed blade 131 and the movable blade 138 are not sharp, the load applied to the fixed blade 131 and the movable blade 138 during lead cutting becomes large, and the displacement amount of the movable body 122, that is, the displacement amount of the strain gauge 148 becomes large. growing. Therefore, when the displacement amount detected by the strain gauge 148 exceeds a preset threshold value, a screen prompting the replacement of the fixed blade 131 and the movable blade 138 is displayed on the display panel 199.
具体的には、カットアンドクリンチユニット100によりリード108が切断される毎に、歪ゲージ148により変位量が検出され、検出された変位量がコントローラ190に入力される。この際、コントローラ190は、歪ゲージ148から変位量が入力される毎に、入力された変位量を記憶装置198に記憶させる。そして、コントローラ190は、歪ゲージ148により検出された変位量が閾値を超えているか否かを判断する。この際、歪ゲージ148により検出された変位量が閾値を超えている場合には、カットアンドクリンチユニットは新たなリードの切断を行うことなく、固定刃131及び可動刃138の交換を促す画面が表示パネル199に表示される。また、固定刃131及び可動刃138の交換を促す画面が表示パネル199に表示され、部品実装機10の作動が停止する。これにより、固定刃131及び可動刃138の切れ味の低下を適切に判断し、適切なタイミングで固定刃131及び可動刃138の交換を行うことができる。
Specifically, every time the lead 108 is cut by the cut and clinch unit 100, the displacement amount is detected by the strain gauge 148, and the detected displacement amount is input to the controller 190. At this time, the controller 190 stores the input displacement amount in the storage device 198 each time the displacement amount is input from the strain gauge 148. Then, the controller 190 determines whether or not the displacement amount detected by the strain gauge 148 exceeds the threshold value. At this time, if the displacement amount detected by the strain gauge 148 exceeds the threshold value, the cut and clinch unit displays a screen prompting the replacement of the fixed blade 131 and the movable blade 138 without cutting a new lead. It is displayed on the display panel 199. Further, a screen prompting the replacement of the fixed blade 131 and the movable blade 138 is displayed on the display panel 199, and the operation of the component mounting machine 10 is stopped. As a result, it is possible to appropriately determine the deterioration of the sharpness of the fixed blade 131 and the movable blade 138, and replace the fixed blade 131 and the movable blade 138 at an appropriate timing.
なお、固定刃131の交換時には、固定交換体146が固定本体144から取り外され、新たな固定交換体146が、位置決めした状態でボルトにより固定本体144に固定される。また、可動刃138の交換時には、可動交換体142が可動本体140から取り外されるとともに、その可動交換体142に貼着されている歪ゲージ148の出力線202がコネクタ200から取り外される。そして、新たな可動交換体142が、位置決めした状態でボルトにより可動本体140に固定されるとともに、新たな可動交換体142に貼着されている歪ゲージ148の出力線202が同じコネクタ200に接続される。このように、固定刃131及び可動刃138の交換が行われると、交換された固定刃131及び可動刃138によりリードの切断チェックが行われる。つまり、交換された固定刃131及び可動刃138によりリードの切断が行われ、その際に貼着された歪ゲージ148により可動刃の変位量が検出される。そして、検出された変位量が閾値以下であるか否かが確認され、検出された変位量が閾値以下である場合には、コントローラは、固定刃131及び可動刃138の交換が適切に完了したと判断する。
When replacing the fixed blade 131, the fixed replacement body 146 is removed from the fixed main body 144, and the new fixed replacement body 146 is fixed to the fixed main body 144 with a bolt in a positioned state. Further, when the movable blade 138 is replaced, the movable replacement body 142 is removed from the movable main body 140, and the output line 202 of the strain gauge 148 attached to the movable replacement body 142 is removed from the connector 200. Then, the new movable exchange body 142 is fixed to the movable main body 140 by bolts in a positioned state, and the output line 202 of the strain gauge 148 attached to the new movable exchange body 142 is connected to the same connector 200. Will be done. When the fixed blade 131 and the movable blade 138 are replaced in this way, the lead cutting check is performed by the replaced fixed blade 131 and the movable blade 138. That is, the lead is cut by the replaced fixed blade 131 and the movable blade 138, and the displacement amount of the movable blade is detected by the strain gauge 148 attached at that time. Then, it is confirmed whether or not the detected displacement amount is equal to or less than the threshold value, and if the detected displacement amount is equal to or less than the threshold value, the controller appropriately completes the replacement of the fixed blade 131 and the movable blade 138. Judge.
なお、上述した閾値はリード部品の種類毎に設定されている。つまり、同じ材質のリードにおいては、リードの線径が太いほど、固定刃131及び可動刃138にかかる負荷は大きくなり、同じ線経のリードにおいては、リードの材質が固いほど、固定刃131及び可動刃138にかかる負荷は大きくなる。このため、リードの線径,材質などに応じて、リードを切断するときの可動刃の変位量の閾値がリード部品の種類毎に設定されている。これにより、リード部品の種類に関わらず、リードを切断するときの固定刃131及び可動刃138の切れ味の低下を適切に判断することができる。
The above-mentioned threshold value is set for each type of lead component. That is, for leads of the same material, the larger the wire diameter of the lead, the greater the load applied to the fixed blade 131 and the movable blade 138, and for leads of the same wire diameter, the harder the material of the lead, the larger the fixed blade 131 and the movable blade 138. The load applied to the movable blade 138 becomes large. Therefore, the threshold value of the displacement amount of the movable blade when cutting the lead is set for each type of lead component according to the wire diameter, material, and the like of the lead. Thereby, regardless of the type of the lead component, it is possible to appropriately determine the deterioration of the sharpness of the fixed blade 131 and the movable blade 138 when cutting the lead.
このように、変位量の閾値がリード部品の種類毎に設定されていることから、同じ種類のリード部品のリードが連続して複数回、切断される毎に歪ゲージ148により検出された変位量は、1つのグループとして、記憶装置198に記憶される。この際、歪ゲージ148により検出された全ての変位量が、それぞれのリードを切断した時の時刻とともに、切断したリード部品の種類を示す情報とを対応付けて記憶装置198に記憶する。なお、同じ種類のリード部品とは、同じ形状,同じ性能,同じ材質,同じ線径,同じ色の部品である。そして、歪ゲージ148により検出された全ての変位量において閾値を超えているか否かが判断される。つまり、カットアンドクリンチユニット100において同じ種類のリード部品のリードが切断される毎に、歪ゲージ148により検出された変位量の変化が確認される。これにより、固定刃131及び可動刃138の切れ味の低下をきめ細やかに判断することが可能となり、固定刃131及び可動刃138の交換のタイミングを適切に判断することができる。特に、線径が太いリード,材質が固いリード等の切断時には、固定刃131及び可動刃138にかかる負荷が大きくなるため、歪ゲージ148により検出される変位量に誤差が生じやすくなる。このような場合には、リードが切断される毎に、歪ゲージ148により検出された変位量の変化を確認すること、つまり、変位量が閾値を超えているか否かを判断することで、確実に固定刃131及び可動刃138の低下の有無を判断することができる。
In this way, since the threshold value of the displacement amount is set for each type of lead component, the displacement amount detected by the strain gauge 148 each time the lead of the lead component of the same type is cut a plurality of times in succession. Are stored in the storage device 198 as one group. At this time, all the displacement amounts detected by the strain gauge 148 are stored in the storage device 198 in association with the time when each lead is cut and the information indicating the type of the cut lead component. The lead parts of the same type are parts having the same shape, the same performance, the same material, the same wire diameter, and the same color. Then, it is determined whether or not the threshold value is exceeded in all the displacement amounts detected by the strain gauge 148. That is, every time the lead of the same type of lead component is cut in the cut and clinch unit 100, the change in the displacement amount detected by the strain gauge 148 is confirmed. As a result, it is possible to finely determine the decrease in sharpness of the fixed blade 131 and the movable blade 138, and it is possible to appropriately determine the timing of replacement of the fixed blade 131 and the movable blade 138. In particular, when cutting a lead having a large wire diameter or a lead having a hard material, the load applied to the fixed blade 131 and the movable blade 138 becomes large, so that an error is likely to occur in the displacement amount detected by the strain gauge 148. In such a case, every time the lead is cut, the change in the displacement amount detected by the strain gauge 148 is confirmed, that is, it is determined whether or not the displacement amount exceeds the threshold value. It is possible to determine whether or not the fixed blade 131 and the movable blade 138 are lowered.
一方で、線径が細いリード,材質が柔らかいリード等の切断時には、固定刃131及び可動刃138にかかる負荷は小さいため、歪ゲージ148により検出される変位量の検出誤差は生じ難い。このようなリードを切断する場合には、リードが切断される毎に、歪ゲージ148により検出したすべての変位量を確認する必要性は低く、歪ゲージ148により複数回、検出した変位量のうちの一部の変位量を確認すればよい。つまり、歪ゲージ148により複数回、検出された歪ゲージ148の変位量のうちの一部の変位量において閾値が超えているか否かを判断すればよい。例えば、線径が細いリード,材質が柔らかいリード等を有するリード部品では、同じ種類のリード部品のリードが連続して複数回、切断される毎に歪ゲージ148により検出された変位量のうちの一部の所定回数の変位量を、記憶装置198は1つのグループとして記憶する。この際、歪ゲージ148により検出された全ての変位量を記憶装置198が記憶する場合と同様に、歪ゲージ148により検出された全ての変位量のうちの一部の所定回数の変位量が、それぞれのリードを切断した時の時刻とともに、リード部品の種類を示す情報とを対応付けて記憶装置198は記憶する。
On the other hand, when cutting a reed with a thin wire diameter or a reed with a soft material, the load applied to the fixed blade 131 and the movable blade 138 is small, so that a detection error of the displacement amount detected by the strain gauge 148 is unlikely to occur. When cutting such a lead, it is not necessary to check all the displacement amounts detected by the strain gauge 148 each time the lead is cut, and among the displacement amounts detected by the strain gauge 148 multiple times. It suffices to confirm the amount of displacement of a part of. That is, it is sufficient to determine whether or not the threshold value is exceeded in the displacement amount of a part of the displacement amounts of the strain gauge 148 detected a plurality of times by the strain gauge 148. For example, in a lead component having a lead having a thin wire diameter, a lead having a soft material, or the like, the displacement amount detected by the strain gauge 148 each time the lead of the same type of lead component is cut a plurality of times in succession. The storage device 198 stores a part of the displacement amount of a predetermined number of times as one group. At this time, as in the case where the storage device 198 stores all the displacement amounts detected by the strain gauge 148, the displacement amount of a part of all the displacement amounts detected by the strain gauge 148 is a predetermined number of times. The storage device 198 stores the time when each lead is cut in association with the information indicating the type of the lead component.
具体的には、リードが10回、切断された場合に、連続する所定回数、例えば、3回分のリードを切断した時の歪みゲージの変位量であって、2回目の切断時の変位量,3回目の切断時の変位量,4回目の切断時の変位量を、記憶装置198は記憶する。また、リードが10回、切断された場合に、連続しない所定回数、例えば、3回分のリードを切断した時の歪みゲージの変位量であって、2回目の切断時の変位量,5回目の切断時の変位量,7回目の切断時の変位量を、記憶装置198は記憶する。なお、何回目のリードを切断した時の歪みゲージの変位量を記憶装置198が記憶するかを、作業者は表示パネル199を通じてコントローラ190に任意に設定することができる。そして、コントローラ190は、そのように記憶装置198に記憶された変位量が閾値を超えているか否かを判断する。このように、線径が細いリード,材質が柔らかいリード等の切断時には、リードが切断される毎に歪ゲージ148により検出された変位量のうちの一部の所定回数の変位量が、記憶装置198に記憶され、その一部の所定回数の変位量が閾値を超えているか否かが判断される。
Specifically, when the lead is cut 10 times, it is the displacement amount of the strain gauge when the lead is cut 10 times in succession, for example, 3 times, and the displacement amount at the time of the second cutting. The storage device 198 stores the displacement amount at the time of the third cutting and the displacement amount at the time of the fourth cutting. Further, when the lead is cut 10 times, the displacement amount of the strain gauge when the lead is cut 10 times, for example, 3 times, which is not continuous, is the displacement amount at the time of the 2nd cutting, and the 5th time. The storage device 198 stores the displacement amount at the time of cutting and the displacement amount at the time of the seventh cutting. The operator can arbitrarily set in the controller 190 how many times the lead is cut and the displacement amount of the strain gauge is stored in the storage device 198 through the display panel 199. Then, the controller 190 determines whether or not the displacement amount stored in the storage device 198 exceeds the threshold value. In this way, when cutting a lead with a thin wire diameter, a lead with a soft material, etc., the displacement amount of a part of the displacement amount detected by the strain gauge 148 each time the lead is cut is stored in the storage device. It is stored in 198, and it is determined whether or not the displacement amount of a part of the predetermined number of times exceeds the threshold value.
また、上述したように、同じ種類のリード部品のリードを切断した時に歪ゲージ148により検出された変位量が、1つのグループとして記憶装置198に記憶されるが、他の種類のリード部品に関しても、歪ゲージ148により検出された変位量が、1つのグループとして記憶装置198に記憶される。つまり、複数種類のリード部品のリードを切断した時に歪ゲージ148により検出された変位量は、リード部品の種類毎のグループに区分けされた状態で記憶装置198に記憶される。具体的には、例えば、A部品のリード切断時に歪ゲージ148により検出された変位量は、A部品のグループとして、記憶装置198に記憶され、B部品のリード切断時に歪ゲージ148により検出された変位量は、B部品のグループとして、記憶装置198に記憶される。このように、部品種類毎に歪ゲージ148による変位量を記憶することで、部品種ごとの変位量の変化を確認することが可能となる。
Further, as described above, the displacement amount detected by the strain gauge 148 when the leads of the same type of lead component is cut is stored in the storage device 198 as one group, but other types of lead components are also stored. , The displacement amount detected by the strain gauge 148 is stored in the storage device 198 as one group. That is, the displacement amount detected by the strain gauge 148 when the leads of a plurality of types of lead parts are cut is stored in the storage device 198 in a state of being divided into groups for each type of lead parts. Specifically, for example, the displacement amount detected by the strain gauge 148 when the lead of the A component is cut is stored in the storage device 198 as a group of the A parts, and is detected by the strain gauge 148 when the lead of the B component is cut. The displacement amount is stored in the storage device 198 as a group of B parts. In this way, by storing the displacement amount by the strain gauge 148 for each component type, it is possible to confirm the change in the displacement amount for each component type.
また、従来のカットアンドクリンチユニットでは、リードの切断を適切に行うために、第1挿入穴130及び第2挿入穴136にリードが挿入されているか否かを検出するための専用のセンサが設けられていた。一方、カットアンドクリンチユニット100では、歪ゲージ148により検出された変位量に基づいて、固定刃131及び可動刃138の交換時期を推定することに加えて、第1挿入穴130及び第2挿入穴136へリードが挿入されたか否かをも確認される。詳しくは、リード切断時において、上述したように、電磁モータ128の作動により可動体122がスライドすることで、第1挿入穴130及び第2挿入穴136に挿入されたリード108が切断され、かつ曲げられる。この際、第1挿入穴130及び第2挿入穴136にリード108が挿入されていれば、固定刃131及び可動刃138にリード108が接触するために、可動体122に負荷がかかることで、可動体122に貼着された歪ゲージ148により変位量が検出される。一方で、第1挿入穴130及び第2挿入穴136にリード108が挿入されていない場合には、電磁モータ128の作動により可動体122がスライドしたとしても、固定刃131及び可動刃138にリード108は接触しないため、可動体122に負荷はかからないことから、可動体122に貼着された歪ゲージ148により変位量は検出されない。そこで、電磁モータ128の作動により可動体122がスライドした際に、歪ゲージ148により変位量が検出された場合には、第1挿入穴130及び第2挿入穴136にリード108が挿入されているものと判断される。一方、電磁モータ128の作動により可動体122がスライドした際に、可動体122に貼着された歪ゲージ148により変位量が検出されない場合には、第1挿入穴130及び第2挿入穴136にリード108が挿入されていないと判断される。このように、カットアンドクリンチユニット100では、可動体122に貼着された歪ゲージ148により検出された変位量に基づいて、第1挿入穴130及び第2挿入穴136へのリードの挿入の有無が確認される。これにより、第1挿入穴130及び第2挿入穴136へのリードの挿入の有無を検出するための専用のセンサを設ける必要がなくなり、コスト,配設スペース等を抑制することができる。
Further, in the conventional cut and clinch unit, in order to properly cut the lead, a dedicated sensor for detecting whether or not the lead is inserted in the first insertion hole 130 and the second insertion hole 136 is provided. Was being done. On the other hand, in the cut and clinch unit 100, in addition to estimating the replacement time of the fixed blade 131 and the movable blade 138 based on the displacement amount detected by the strain gauge 148, the first insertion hole 130 and the second insertion hole It is also confirmed whether or not the lead has been inserted into 136. Specifically, at the time of lead cutting, as described above, the movable body 122 slides due to the operation of the electromagnetic motor 128, so that the leads 108 inserted in the first insertion hole 130 and the second insertion hole 136 are cut and Can be bent. At this time, if the lead 108 is inserted into the first insertion hole 130 and the second insertion hole 136, the lead 108 comes into contact with the fixed blade 131 and the movable blade 138, so that a load is applied to the movable body 122. The displacement amount is detected by the strain gauge 148 attached to the movable body 122. On the other hand, when the lead 108 is not inserted into the first insertion hole 130 and the second insertion hole 136, even if the movable body 122 slides due to the operation of the electromagnetic motor 128, the lead 108 leads to the fixed blade 131 and the movable blade 138. Since the 108 does not come into contact with the movable body 122, no load is applied to the movable body 122, so that the displacement amount is not detected by the strain gauge 148 attached to the movable body 122. Therefore, when the displacement amount is detected by the strain gauge 148 when the movable body 122 slides due to the operation of the electromagnetic motor 128, the leads 108 are inserted into the first insertion hole 130 and the second insertion hole 136. It is judged to be a thing. On the other hand, when the movable body 122 slides due to the operation of the electromagnetic motor 128 and the displacement amount is not detected by the strain gauge 148 attached to the movable body 122, the first insertion hole 130 and the second insertion hole 136 are used. It is determined that the lead 108 is not inserted. As described above, in the cut and clinch unit 100, the presence or absence of the lead inserted into the first insertion hole 130 and the second insertion hole 136 based on the displacement amount detected by the strain gauge 148 attached to the movable body 122. Is confirmed. As a result, it is not necessary to provide a dedicated sensor for detecting the presence / absence of insertion of the lead into the first insertion hole 130 and the second insertion hole 136, and the cost, the arrangement space, and the like can be suppressed.

なお、本発明は、上記実施例に限定されるものではなく、当業者の知識に基づいて種々の変更、改良を施した種々の態様で実施することが可能である。具体的には、例えば、上記実施例では、固定刃131及び可動刃138によりリードが切断されている、つまり、2枚の切断刃によりリードが切断されているが、例えば、1枚の切断刃によりリードが切断されてもよい。例えば、1枚の切断刃により、回路基材12の貫通穴104に挿入されたリードを、貫通穴104の内壁面に押し当てながら切断してもよい。
The present invention is not limited to the above embodiment, and can be carried out in various embodiments with various changes and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, the lead is cut by the fixed blade 131 and the movable blade 138, that is, the lead is cut by two cutting blades, but for example, one cutting blade. May cut the lead. For example, the lead inserted into the through hole 104 of the circuit base material 12 may be cut while being pressed against the inner wall surface of the through hole 104 by one cutting blade.
また、上記実施例では、リードを切断するとともに、リードを屈曲するカットアンドクリンチユニット100に本発明が適用されているが、リードを切断するのみで屈曲しないリード切断装置に本発明が適用されてもよい。

また、上記実施例では、可動体122の可動交換体142が交換される際に、新たに取り付けられる可動交換体142には新たな歪ゲージ148が貼着されている。つまり、可動交換体142に貼着されている歪ゲージ148は再利用されない。しかしながら、可動交換体142に貼着されている歪ゲージ148を再利用してもよい。例えば、歪ゲージ148を可動交換体142にネジ止めやシール材、あるいははめ込み式などを利用して、容易に着脱可能に配設し、可動交換体142が可動本体140から取り外された場合に、その可動交換体142から歪ゲージ148を取り外す。そして、その取り外した歪ゲージ148を、新たな可動交換体142に配設してもよい。
Further, in the above embodiment, when the movable exchange body 142 of the movable body 122 is exchanged, a new strain gauge 148 is attached to the movable exchange body 142 newly attached. That is, the strain gauge 148 attached to the movable exchange 142 is not reused. However, the strain gauge 148 attached to the movable exchanger 142 may be reused. For example, when the strain gauge 148 is easily attached to and detached from the movable exchange body 142 by screwing, sealing material, or a fitting type, and the movable exchange body 142 is removed from the movable main body 140, the strain gauge 148 is easily attached and detached. The strain gauge 148 is removed from the movable exchanger 142. Then, the removed strain gauge 148 may be arranged in a new movable exchange body 142.
また、上記実施例では、可動交換体142に貼着した歪ゲージ148の検出値に基づいて可動刃138と固定刃131の交換時期が推定されているが、歪ゲージ148に代えて、圧力センサ,応力センサ等を用いてもよい。また、交換する対象は1対の交換体である必要はなく、可動交換体のみ、あるいは固定交換体のみとしても良い。
Further, in the above embodiment, the replacement time of the movable blade 138 and the fixed blade 131 is estimated based on the detected value of the strain gauge 148 attached to the movable exchange body 142, but instead of the strain gauge 148, the pressure sensor is used. , A stress sensor or the like may be used. Further, the target to be exchanged does not have to be a pair of exchange bodies, and may be only a movable exchange body or only a fixed exchange body.
また、上記実施例では、歪ゲージ148が可動交換体142の上端部、つまり、可動刃138に近い位置に配設されているが、可動刃138から離れた位置に配設されてもよい。また、可動交換体142でなく、可動本体140と可動交換体142との間に、歪ゲージ148が配設されてもよい。さらに言えば、可動体122に代えて、固定体120に歪ゲージ148が配設されてもよい。また歪ゲージ148は、1対の可動交換体と固定交換体のそれぞれに配設しても良い。また1対の交換体のうちのいずれかの交換体にのみ歪ゲージを配設して、使用する歪ゲージの数を削減してもよい。
Further, in the above embodiment, the strain gauge 148 is arranged at the upper end of the movable exchange body 142, that is, at a position close to the movable blade 138, but may be arranged at a position away from the movable blade 138.

Furthermore, instead of the movable body 122, the strain gauge 148 may be arranged on the fixed body 120. Further, the strain gauge 148 may be arranged on each of the pair of movable exchanges and the fixed exchanges. Further, the strain gauge may be arranged only in one of the pair of exchanges to reduce the number of strain gauges used.
