Abstract
This inspection device reduces measurement error. The inspection device is provided with: a component mounting unit which includes a groove extending in a first direction and comprising a bottom part which extends in the first direction and a pair of inclined surfaces which extend in the first direction and separate from each other upwards from the bottom part; and a pair of probes which are provided so as to enable connection, from both ends of the groove in the first direction, to each of a pair of electrodes of an electronic component mounted on the component mounting unit. The inspection device inspects the electronic component which, when the pair of electrodes thereof are aligned in the first direction, has a smaller dimension on the bottom surface in a second direction than the dimension of the aforementioned bottom part of the component mounting unit in the second direction, the second direction being the direction orthogonal in the horizontal direction with respect to the first direction. When inspecting an electronic component which has a smaller dimension in the second direction than the dimension in the second direction of the bottom part of the component mounting unit, the electronic component is arranged in the component mounting unit in a state in which the bottom surface of the electronic component is in contact with the bottom part of the component mounting unit. For that reason, frictional force between the bottom surface of the electronic component and the bottom part of the component mounting unit prevents disturbance of the attitude of the mounted electronic component. Consequently, measurement error is reduced in the measurement of electric properties of the electronic component.

As shown in FIGS. 2 to 4, the
保持台32は、部品載置部44と、部品載置部44を保持する載置部保持体46とを含む。部品載置部44の上面には溝44cが形成され、部品sが載せられる。溝44cは、x方向両側の傾斜面441L、441Rと、傾斜面441L、441R間に設けられた底部442とを含む(図11参照)。溝44cは、略V形状とされているため、部品sの位置が精度よく決まる。なお、溝44cは、完全なV形状ではないが、略V形状であるため、以後の説明において、溝44cをV溝44cと称する。
部品載置部44は、導電性、耐摩耗性を有し、かつ、酸化が進み難い材料で製造されたものとすることができる。部品載置部44は、複数の導電性を有する部材を介してベース部30に電気的に接続されるが、ベース部30が接地されることにより、部品載置部44も接地される。本実施例においては、部品載置部44が載置部保持体46に当接し、かつ、締結部47によって固定されるとともに、載置部保持体46が本体29にストッパ80(図3参照)を介して当接し、本体29がベース部30に締結部31によって固定される。そして、載置部保持体46、ストッパ80、本体29、ベース部30、締結部31、47等は導電性を有するものである。したがって、部品載置部44は接地されるのである。
このように、部品載置部44が導電性を有する材料で製造され、かつ、接地されることにより、部品載置部44に載置させられた部品sの除電を行うことができる。また、部品載置部44が、耐摩耗性を有する材料で製造されることにより、部品載置部44の摩耗を抑制し、耐久性を向上させることができる。さらに、酸化が進み難い材料、すなわち、金属の酸化被膜である不動態皮膜が形成され得る材料で製造されることにより、部品載置部44が錆び難くすることができる。錆が部品sに付き難くすること等ができ、部品sの電気的特性の測定精度の低下を抑制することができる。例えば、部品載置部44は、アルミニウム合金またはステンレス材料等によって製造されたものとすることができる。 Theholding base 32 includes a component placement portion 44 and a placement portion holding body 46 that holds the component placement portion 44. A groove 44c is formed on the upper surface of the component placement portion 44, and the component s is placed thereon. The groove 44c includes inclined surfaces 441L and 441R on both sides in the x direction and a bottom portion 442 provided between the inclined surfaces 441L and 441R (see FIG. 11). Since the groove 44c is substantially V-shaped, the position of the component s is accurately determined. The groove 44c is not completely V-shaped, but is substantially V-shaped. Therefore, in the following description, the groove 44c is referred to as a V-groove 44c.
Thecomponent mounting portion 44 can be made of a material that has conductivity and wear resistance and is difficult to oxidize. The component placement unit 44 is electrically connected to the base unit 30 via a plurality of conductive members, but the component placement unit 44 is also grounded when the base unit 30 is grounded. In this embodiment, the component mounting portion 44 abuts on the mounting portion holding body 46 and is fixed by the fastening portion 47, and the mounting portion holding body 46 is attached to the main body 29 with a stopper 80 (see FIG. 3). The main body 29 is fixed to the base portion 30 by the fastening portion 31. And the mounting part holding body 46, the stopper 80, the main body 29, the base part 30, the fastening parts 31, 47, etc. have electroconductivity. Therefore, the component mounting part 44 is grounded.
As described above, thecomponent placement unit 44 is manufactured from a conductive material and is grounded, so that the charge of the component s placed on the component placement unit 44 can be eliminated. Moreover, since the component mounting part 44 is manufactured with the material which has abrasion resistance, abrasion of the component mounting part 44 can be suppressed and durability can be improved. Furthermore, the component mounting part 44 can be made difficult to rust by being manufactured from a material that is difficult to oxidize, that is, a material that can form a passive film that is a metal oxide film. Rust can be made difficult to adhere to the component s, and a decrease in measurement accuracy of the electrical characteristics of the component s can be suppressed. For example, the component mounting part 44 can be manufactured by an aluminum alloy or a stainless material.
部品載置部44は、導電性、耐摩耗性を有し、かつ、酸化が進み難い材料で製造されたものとすることができる。部品載置部44は、複数の導電性を有する部材を介してベース部30に電気的に接続されるが、ベース部30が接地されることにより、部品載置部44も接地される。本実施例においては、部品載置部44が載置部保持体46に当接し、かつ、締結部47によって固定されるとともに、載置部保持体46が本体29にストッパ80(図3参照)を介して当接し、本体29がベース部30に締結部31によって固定される。そして、載置部保持体46、ストッパ80、本体29、ベース部30、締結部31、47等は導電性を有するものである。したがって、部品載置部44は接地されるのである。
このように、部品載置部44が導電性を有する材料で製造され、かつ、接地されることにより、部品載置部44に載置させられた部品sの除電を行うことができる。また、部品載置部44が、耐摩耗性を有する材料で製造されることにより、部品載置部44の摩耗を抑制し、耐久性を向上させることができる。さらに、酸化が進み難い材料、すなわち、金属の酸化被膜である不動態皮膜が形成され得る材料で製造されることにより、部品載置部44が錆び難くすることができる。錆が部品sに付き難くすること等ができ、部品sの電気的特性の測定精度の低下を抑制することができる。例えば、部品載置部44は、アルミニウム合金またはステンレス材料等によって製造されたものとすることができる。 The

As described above, the
固定子34、可動子36は、それぞれ、互いに対向する対向面34f、36fを有し、これら一対の対向面34f、36fによって部品sの電極が把持される。固定子34は固定子保持体55を介して本体29に固定される。可動子36は、可動子保持体56に一体的に移動可能に保持されたものであり、固定子34に対して接近・離間可能とされる。本実施例において、対向面36fは、断面が三角形状を成し、V溝44cに沿って移動可能とされる。換言すれば、可動子36の対向面36fの形状は、ほぼV溝44cに対応する形状とされ、可動子36の対向面36f、固定子34の対向面34fおよび保持台32のV溝44cは、ほぼ同一高さに位置する。そのため、部品sがV溝44c内のいずれにあっても、一対の対向面34f、36fによって部品sが把持可能とされる。
また、可動子36は、本実施例において、y方向(移動方向)に伸びた長手部材であり、後退端において可動子保持体56に保持される。さらに、対向面36fを含む先端部より後部は、先端部よりx方向にはみ出す部分を有さない形状を成す。その結果、保持台32と可動子36とは互いに相対移動可能とされ、保持台32は、V溝44の底部が可動子36を下方に位置する状態で、対向面36fの前方へ移動したり後方へ移動したりすることが可能である。
さらに、可動子36と固定子34とから成る一対の測定子37、LCR 検出部42、図示を省略する電源装置等を含む電気回路58が形成される。これら固定子34と可動子36との間に電流が供給されるとともに流れた電流が検出され、これらの関係に基づいて部品sの電気的特性がLCR検出部42によって測定される。LCR 検出部42は、L,C,Rを検出する検出部に限らず、L,C,R,Z´等の電気的特性を表す物理量の1つ以上を検出するものとすることができる。なお、図2~4の符号58a、bは、一対の測定子37の電気回路58への接続部である。 Thestator 34 and the movable element 36 have opposing surfaces 34f and 36f that face each other, and the electrodes of the component s are held by the pair of opposing surfaces 34f and 36f. The stator 34 is fixed to the main body 29 via a stator holder 55. The mover 36 is held by a mover holder 56 so as to be movable integrally, and can be moved toward and away from the stator 34. In the present embodiment, the opposing surface 36f has a triangular cross section and is movable along the V groove 44c. In other words, the shape of the facing surface 36f of the mover 36 is substantially the shape corresponding to the V-groove 44c, and the facing surface 36f of the mover 36, the facing surface 34f of the stator 34, and the V-groove 44c of the holding base 32 are Located at almost the same height. Therefore, regardless of the part s in the V groove 44c, the part s can be gripped by the pair of opposed surfaces 34f and 36f.
In the present embodiment, themover 36 is a longitudinal member extending in the y direction (movement direction), and is held by the mover holding body 56 at the retracted end. Further, the rear portion of the front end portion including the facing surface 36f has a shape that does not have a portion protruding from the front end portion in the x direction. As a result, the holding table 32 and the mover 36 can be moved relative to each other, and the holding table 32 can move forward of the facing surface 36f with the bottom of the V-groove 44 positioned below the mover 36. It is possible to move backward.
Further, anelectric circuit 58 including a pair of measuring elements 37 including a mover 36 and a stator 34, an LCR detector 42, a power supply device (not shown), and the like is formed. A current is supplied between the stator 34 and the mover 36, and the flowing current is detected. Based on these relationships, the electrical characteristics of the component s are measured by the LCR detector 42. The LCR detector 42 is not limited to a detector that detects L, C, and R, and can detect one or more physical quantities representing electrical characteristics such as L, C, R, and Z ′. Reference numerals 58a and 58b in FIGS. 2 to 4 are connecting portions of the pair of measuring elements 37 to the electric circuit 58.
また、可動子36は、本実施例において、y方向(移動方向)に伸びた長手部材であり、後退端において可動子保持体56に保持される。さらに、対向面36fを含む先端部より後部は、先端部よりx方向にはみ出す部分を有さない形状を成す。その結果、保持台32と可動子36とは互いに相対移動可能とされ、保持台32は、V溝44の底部が可動子36を下方に位置する状態で、対向面36fの前方へ移動したり後方へ移動したりすることが可能である。
さらに、可動子36と固定子34とから成る一対の測定子37、LCR 検出部42、図示を省略する電源装置等を含む電気回路58が形成される。これら固定子34と可動子36との間に電流が供給されるとともに流れた電流が検出され、これらの関係に基づいて部品sの電気的特性がLCR検出部42によって測定される。LCR 検出部42は、L,C,Rを検出する検出部に限らず、L,C,R,Z´等の電気的特性を表す物理量の1つ以上を検出するものとすることができる。なお、図2~4の符号58a、bは、一対の測定子37の電気回路58への接続部である。 The

In this embodiment, theguide rods 74 to 77 are shared by the holding table moving device 40 and the mover moving device 41, and the stoppers 80 and 82 can be considered as components of the holding table moving device 40.
As shown in FIG. 3, the gap Ld between the front end portion of thestopper 82 when the mover 36 is at the retracted end position and the mounting portion holder 46 when the holding base 32 is at the advanced end position. Is a distance in which relative movement between the mover 36 and the holding table 32 is allowed.
また、図3に示すように、可動子保持体56の固定子側にはストッパ82が設けられ、本体29の固定子保持体55を保持する部分にはストッパ80が設けられる。ストッパ82は、可動子保持体56と保持台32(載置部保持体46)との接近限度を規定するものであり、ストッパ80は、固定子34(本体29)と保持台32(載置部保持体46)との接近限度を規定するものである。
本実施例において、ガイドロッド74~77は、保持台移動装置40、可動子移動装置41に共有され、ストッパ80,82は保持台移動装置40の構成要素であると考えることができる。
なお、図3に示すように、可動子36が後退端位置にある場合のストッパ82の前端部と、保持台32が前進端位置にある場合の載置部保持体46との間の隙間Ldが、可動子36と保持台32との相対移動が許容される距離である。 A pair of
Further, as shown in FIG. 3, a
In this embodiment, the
As shown in FIG. 3, the gap Ld between the front end portion of the
図3に示すように、保持台32の部品載置部44の下方には永久磁石130が設けられている。永久磁石130は、V溝44cのx方向の中心に対してx方向にほぼ対称に設けられている。永久磁石130は、部品sの電極を磁力により引き寄せるので、部品sを吸着した吸着ノズル18が、部品sをV溝44cに載置する際に、V溝44cに載置されたはずの部品sが静電気により吸着ノズル18に貼りつくことが低減される。永久磁石130は、部品sを吸着ノズル18に貼り付ける静電気よりも大きな磁力を有する。ただし、永久磁石130の磁力は、検査装置22による部品sの電気的特性の検査に影響を与えない大きさとなっている。また、後述するように、検査装置22は、電気的特性の測定の際、部品sとV溝44cとを相対移動させるが、永久磁石130の磁力は、この相対移動を許容する大きさである。
As shown in FIG. 3, a permanent magnet 130 is provided below the component placement portion 44 of the holding table 32. The permanent magnet 130 is provided substantially symmetrically in the x direction with respect to the center of the V groove 44c in the x direction. Since the permanent magnet 130 attracts the electrode of the part s by magnetic force, when the suction nozzle 18 that sucks the part s places the part s in the V groove 44c, the part s that should have been placed in the V groove 44c. Sticking to the suction nozzle 18 due to static electricity is reduced. The permanent magnet 130 has a magnetic force larger than the static electricity that attaches the component s to the suction nozzle 18. However, the magnetic force of the permanent magnet 130 has a magnitude that does not affect the inspection of the electrical characteristics of the component s by the inspection device 22. Further, as will be described later, the inspection device 22 relatively moves the component s and the V-groove 44c when measuring the electrical characteristics, but the magnetic force of the permanent magnet 130 is large enough to allow this relative movement. .

段取り替えが行われる場合等、新たなテープフィーダ14のセット、テープフィーダ14の交換等が行われた場合等に、そのテープフィーダ14に保持された部品sの電気的特性が測定され、そのテープフィーダ14(または部品s)が適切なものであるか否かが検査される。また、その検査結果がディスプレイ116に表示される。不適切である場合には、テープフィーダ14が取り替えられる。 Hereinafter, the operation of the mounting machine will be described.
When anew tape feeder 14 is set, the tape feeder 14 is replaced, etc., when the setup is changed, the electrical characteristics of the parts s held by the tape feeder 14 are measured, and the tape It is inspected whether the feeder 14 (or part s) is appropriate. In addition, the inspection result is displayed on the display 116. If it is inappropriate, the tape feeder 14 is replaced.
段取り替えが行われる場合等、新たなテープフィーダ14のセット、テープフィーダ14の交換等が行われた場合等に、そのテープフィーダ14に保持された部品sの電気的特性が測定され、そのテープフィーダ14(または部品s)が適切なものであるか否かが検査される。また、その検査結果がディスプレイ116に表示される。不適切である場合には、テープフィーダ14が取り替えられる。 Hereinafter, the operation of the mounting machine will be described.
When a
部品sの電気的特性は、図7(a)のフローチャートで表されるLCR 測定プログラムの実行により測定される。また、保持台32、可動子36の動き、保持台位置センサ120、可動子位置センサ118の状態を図7(b)に示す。
検査装置22は、常には、図9(a)に示す初期状態にある。可動子36は後退端位置にあり、保持台32は前進端位置、すなわち、ストッパ80に当接した位置にある。この状態において、保持台32は、内部導通等によりアースされた状態にある。保持台32のV溝44cの上方に可動子36が存在せず、部品sを載置可能な状態にある。また、カバー部50は固定子34の両側(x方向に隔たって)に位置する。可動子位置センサ118、保持台位置センサ120は、いずれもON状態にある。
ステップ1(以下、S1と略称する。他のステップについても同様とする)において、部品sの電気的特性の測定指令が出されたか否かが判定される。段取り替えが行われる場合等には電気的特性の測定指令が出される。測定指令が出されると、S2において、装着ヘッド16が移動させられ、例えば、新たに取り付けられたテープフィーダ14に保持された部品sが吸着ノズル18によってピックアップされて、保持台32のV溝44c上に載せられる。吸着ノズル18が下降させられ、部品sが開放されることにより、部品sがV溝44c上に載置させられたことがわかる。吸着ノズル18にピックアップされた部品sは、予め定められた姿勢、具体的には、両端の電極が、一対の測定子37の各々に対向する向きで、V溝44c上に載せられる。部品sの両端の電極が、V溝44cの下方に設けられた永久磁石130に引き寄せられるため、V溝44c上に一旦載置された部品sが、静電気により吸着ノズル18に貼り付いて吸着ノズル18とともに上昇した後にV溝44c上に落下して部品sの姿勢が乱れた結果、部品sの載置向きが変わることが低減される。部品sの載置向きが変わり、部品sの両端の電極が一対の測定子37の各々に対向しない向きに載置された場合、部品sの両端の電極と一対の測定子37とが電気的に接続できず、測定エラーとなる。永久磁石130の磁力により、部品sの載置向きは、部品sの両端の電極が一対の測定子37の各々に対向する向きとなるので、測定エラーの発生が低減される。 The electrical characteristics of the component s are measured by executing the LCR measurement program represented by the flowchart of FIG. FIG. 7B shows the movements of the holding table 32 and themover 36, and the states of the holding table position sensor 120 and the mover position sensor 118.
Theinspection device 22 is always in the initial state shown in FIG. The mover 36 is in the retreat end position, and the holding base 32 is in the advance end position, that is, the position in contact with the stopper 80. In this state, the holding table 32 is in a state of being grounded by internal conduction or the like. The mover 36 does not exist above the V-groove 44c of the holding base 32, and the component s can be placed. The cover 50 is located on both sides of the stator 34 (separated in the x direction). Both the mover position sensor 118 and the holding stand position sensor 120 are in the ON state.
In step 1 (hereinafter abbreviated as S1. The same applies to other steps), it is determined whether or not a measurement command for the electrical characteristics of the component s has been issued. When the setup change is performed, an electrical characteristic measurement command is issued. When the measurement command is issued, the mountinghead 16 is moved in S2, for example, the component s held by the newly attached tape feeder 14 is picked up by the suction nozzle 18, and the V groove 44c of the holding table 32 is picked up. It is put on. It is understood that the component s is placed on the V-groove 44c by lowering the suction nozzle 18 and opening the component s. The component s picked up by the suction nozzle 18 is placed on the V-groove 44c in a predetermined posture, specifically, with the electrodes on both ends facing each of the pair of measuring elements 37. Since the electrodes at both ends of the component s are attracted to the permanent magnet 130 provided below the V-groove 44c, the component s once placed on the V-groove 44c adheres to the suction nozzle 18 due to static electricity and is attracted to the suction nozzle. As a result of falling on the V-groove 44c and being disturbed by the posture of the component s after being lifted together with 18, the change in the mounting direction of the component s is reduced. When the placement direction of the part s is changed and the electrodes at both ends of the part s are placed in a direction not facing each of the pair of measuring elements 37, the electrodes at both ends of the part s and the pair of measuring elements 37 are electrically connected. Cannot connect to, and measurement error occurs. Due to the magnetic force of the permanent magnet 130, the mounting direction of the component s is such that the electrodes at both ends of the component s face each of the pair of measuring elements 37, so that the occurrence of measurement errors is reduced.
検査装置22は、常には、図9(a)に示す初期状態にある。可動子36は後退端位置にあり、保持台32は前進端位置、すなわち、ストッパ80に当接した位置にある。この状態において、保持台32は、内部導通等によりアースされた状態にある。保持台32のV溝44cの上方に可動子36が存在せず、部品sを載置可能な状態にある。また、カバー部50は固定子34の両側(x方向に隔たって)に位置する。可動子位置センサ118、保持台位置センサ120は、いずれもON状態にある。
ステップ1(以下、S1と略称する。他のステップについても同様とする)において、部品sの電気的特性の測定指令が出されたか否かが判定される。段取り替えが行われる場合等には電気的特性の測定指令が出される。測定指令が出されると、S2において、装着ヘッド16が移動させられ、例えば、新たに取り付けられたテープフィーダ14に保持された部品sが吸着ノズル18によってピックアップされて、保持台32のV溝44c上に載せられる。吸着ノズル18が下降させられ、部品sが開放されることにより、部品sがV溝44c上に載置させられたことがわかる。吸着ノズル18にピックアップされた部品sは、予め定められた姿勢、具体的には、両端の電極が、一対の測定子37の各々に対向する向きで、V溝44c上に載せられる。部品sの両端の電極が、V溝44cの下方に設けられた永久磁石130に引き寄せられるため、V溝44c上に一旦載置された部品sが、静電気により吸着ノズル18に貼り付いて吸着ノズル18とともに上昇した後にV溝44c上に落下して部品sの姿勢が乱れた結果、部品sの載置向きが変わることが低減される。部品sの載置向きが変わり、部品sの両端の電極が一対の測定子37の各々に対向しない向きに載置された場合、部品sの両端の電極と一対の測定子37とが電気的に接続できず、測定エラーとなる。永久磁石130の磁力により、部品sの載置向きは、部品sの両端の電極が一対の測定子37の各々に対向する向きとなるので、測定エラーの発生が低減される。 The electrical characteristics of the component s are measured by executing the LCR measurement program represented by the flowchart of FIG. FIG. 7B shows the movements of the holding table 32 and the
The
In step 1 (hereinafter abbreviated as S1. The same applies to other steps), it is determined whether or not a measurement command for the electrical characteristics of the component s has been issued. When the setup change is performed, an electrical characteristic measurement command is issued. When the measurement command is issued, the mounting
そして、吸着ノズル18が部品sをV溝44c上に載置させて上昇端に達したことがノズル高さセンサ122によって検出されると、S3において、電磁弁装置72の制御により可動子36が前進させられ、可動子位置センサ118がONからOFFに切り換えられる。可動子36の先端の対向面36fは、部品載置部44のV溝44cに沿って前進させられ、対向面36fと固定子34の対向面34fとによって部品sがクランプされる{図9(b)}。本実施例においては、後退端位置から部品sをクランプするまでの可動子36のストロークL1(図3参照)は、クランプされる部品sの大きさ等で決まり、予め決められている。可動子36の前進開始時から、可動子36がストロークL1 前進するまでに要する時間である前進時間が経過した後に、可変絞りの制御等により、可動子36の前進が停止させられる。前進時間は、タイマ124によって計測される。この保持台32が前進端位置にあり、可動子36が前進させられ、一対の対向面34f、36fにより部品sがクランプされた状態がクランプ状態である。
When the nozzle height sensor 122 detects that the suction nozzle 18 has placed the component s on the V-groove 44c and has reached the rising end, the mover 36 is controlled by the solenoid valve device 72 in S3. The mover is moved forward, and the mover position sensor 118 is switched from ON to OFF. The opposing surface 36f at the tip of the mover 36 is advanced along the V groove 44c of the component mounting portion 44, and the component s is clamped by the opposing surface 36f and the opposing surface 34f of the stator 34 {FIG. b)}. In the present embodiment, the stroke L1 (see FIG. 3) of the mover 36 from the retracted end position to the clamping of the part s is determined by the size of the part s to be clamped and the like. After the advancement time, which is the time required for the mover 36 to move forward by the stroke L1 from the start of the advancement of the mover 36, elapses, the advancement of the mover 36 is stopped by control of the variable throttle or the like. The advance time is measured by the timer 124. The state in which the holding base 32 is at the forward end position, the movable element 36 is advanced, and the component s is clamped by the pair of opposed surfaces 34f and 36f is a clamped state.
S4において、電磁弁装置69の制御により保持台32が後退させられ、保持台位置センサ120がONからOFFに切り換えられる。保持台32は、ストッパ82に当接するまで後退させられ{図9(c)}、その位置で保持される。その間の保持台32のストロークはL2(図3参照)である。
L2=Ld-L1
本実施例においては、ストロークL2 は設定値Lx以上の大きさとされていて(L2≧Lx)、部品載置部44が部品sから設定値Lx以上離間させられる。導電性を有する部材(部品載置部44)が電気的特性の測定時に部品sの近傍に位置すると静電誘導が起きたり、渦電流が生じたりする等、電気的特性を正確に検出することができない。それに対して、部品載置部44を部品sから設定値Lx以上離間させれば(部品載置部44と部品sとの最短距離が設定値Lx以上とすれば)、部品載置部44が部品sの近傍に位置することに起因して生じる電気的特性の測定誤差を小さくすることができる。このように、設定値Lxは、部品載置部44が部品sの電気的特性の測定に影響を及ぼし難い距離であり、予め実験等により取得された値である。この状態が測定状態である。
なお、保持台32の後退開始時から、保持台32がストロークL2 後退するのに要する時間である後退時間Ta が経過した後に、電磁弁装置69の制御により保持台32の位置が保持される。後退時間Taは、タイマ124によって計測される。 In S4, the holding table 32 is moved backward by the control of theelectromagnetic valve device 69, and the holding table position sensor 120 is switched from ON to OFF. The holding table 32 is retracted until it comes into contact with the stopper 82 {FIG. 9 (c)}, and is held at that position. During this period, the stroke of the holding table 32 is L2 (see FIG. 3).
L2 = Ld-L1
In the present embodiment, the stroke L2 is set to be larger than the set value Lx (L2 ≧ Lx), and thecomponent placement unit 44 is separated from the component s by the set value Lx or more. When the conductive member (component mounting portion 44) is positioned in the vicinity of the component s when measuring the electrical property, the electrical property such as electrostatic induction or eddy current is detected accurately. I can't. On the other hand, if the component placement unit 44 is separated from the component s by the set value Lx or more (if the shortest distance between the component placement unit 44 and the component s is greater than the set value Lx), the component placement unit 44 is It is possible to reduce the measurement error of electrical characteristics caused by being located in the vicinity of the component s. As described above, the set value Lx is a distance at which the component placement unit 44 hardly affects the measurement of the electrical characteristics of the component s, and is a value acquired in advance through experiments or the like. This state is a measurement state.
Note that the position of the holding table 32 is held by the control of theelectromagnetic valve device 69 after the retraction time Ta, which is the time required for the holding table 32 to move backward by the stroke L2, elapses from the time when the holding table 32 starts to move backward. The backward time Ta is measured by the timer 124.
L2=Ld-L1
本実施例においては、ストロークL2 は設定値Lx以上の大きさとされていて(L2≧Lx)、部品載置部44が部品sから設定値Lx以上離間させられる。導電性を有する部材(部品載置部44)が電気的特性の測定時に部品sの近傍に位置すると静電誘導が起きたり、渦電流が生じたりする等、電気的特性を正確に検出することができない。それに対して、部品載置部44を部品sから設定値Lx以上離間させれば(部品載置部44と部品sとの最短距離が設定値Lx以上とすれば)、部品載置部44が部品sの近傍に位置することに起因して生じる電気的特性の測定誤差を小さくすることができる。このように、設定値Lxは、部品載置部44が部品sの電気的特性の測定に影響を及ぼし難い距離であり、予め実験等により取得された値である。この状態が測定状態である。
なお、保持台32の後退開始時から、保持台32がストロークL2 後退するのに要する時間である後退時間Ta が経過した後に、電磁弁装置69の制御により保持台32の位置が保持される。後退時間Taは、タイマ124によって計測される。 In S4, the holding table 32 is moved backward by the control of the

In the present embodiment, the stroke L2 is set to be larger than the set value Lx (L2 ≧ Lx), and the
Note that the position of the holding table 32 is held by the control of the
S5において、吸着ノズル18により部品sが開放され、V溝44c上に載せられた時から、設定時間である除電時間が経過するのが待たれる。テープフィーダ14に保持された部品sの各々は、テープフィーダ14の運搬に伴う振動、物との接触等に起因して生じた静電気により帯電した状態にある。この帯電された部品sが、導電性を有する材料で製造され、かつ、アースされた部品載置部44に載置されることにより除電されたり、空気中への放電により除電されたりする。除電時間は、部品sが有していると推定される容量の静電気を除去するのに要する時間であり、予め実験等により求めたり、部品sの大きさ、特性等に基づいて理論的に求めたりすること等ができる。部品sが部品保持台44に載せられてからの経過時間が除電時間に達すると、S5の判定がYESとなり、S6において部品sの電気的特性が測定される。
そして、電気的特性の測定に要する時間である測定時間が経過すると、S7が実行されるのであるが、測定時間は部品sの種類等によって決まる時間としても、一定の時間としてもよい。いずれにしても予め取得されて記憶されている。 In S5, the part s is opened by thesuction nozzle 18 and is placed on the V-groove 44c. Each of the parts s held by the tape feeder 14 is in a state of being charged by static electricity generated due to vibration accompanying transportation of the tape feeder 14, contact with an object, or the like. The charged component s is made of a conductive material and is placed on the grounded component placing portion 44 to be discharged or discharged to discharge in the air. The static elimination time is the time required to remove the static electricity of the capacity estimated to be possessed by the part s, and is obtained in advance by experiments or theoretically based on the size, characteristics, etc. of the part s. You can do it. When the elapsed time after the component s is placed on the component holding table 44 reaches the static elimination time, the determination in S5 is YES, and the electrical characteristics of the component s are measured in S6.
When the measurement time, which is the time required for measuring the electrical characteristics, elapses, S7 is executed. However, the measurement time may be determined by the type of the part s or the like, or may be a fixed time. In any case, it is acquired and stored in advance.

When the measurement time, which is the time required for measuring the electrical characteristics, elapses, S7 is executed. However, the measurement time may be determined by the type of the part s or the like, or may be a fixed time. In any case, it is acquired and stored in advance.
測定時間が経過し、部品sの電気的特性の測定が終了すると、S7において、電磁弁装置72の制御により可動子36が後退させられる。後退端に達すると、可動子位置センサ118がONとなる。S8において、電磁弁装置69の制御により、保持台32が後退させられる{図9(d)}。保持台32が測定状態から後退端位置にある可動子36のストッパ82に当接するまでのストロークはL1 である。そのため、保持台32がストロークL1 後退するのに要する時間である後退時間Tb が経過した後に、ストッパ82に当接したとわかる。図9(d)に示すように、保持台32は、可動子36の対向面36fより後方に位置し、一対の対向面34f、36fの間の下方に存在しない。この状態が廃棄状態である。
保持台32がストッパ82に当接するまで後退させられると、S9において、電磁弁装置69の制御により、エアシリンダ64においてエア室64bがエア源68に連通させられ、エア室64aがエア通路60に連通させられる。保持台32が前進させられ、ストッパ80に当たると保持台位置センサ120がONとなる。保持台32は、一対の対向面34f、36fの間に位置し(V溝44が対向面34f、36fの間の下方に位置し)、V溝44cの上方が空間とされている。そのため、部品sが載置可能とされる。この状態が初期状態である。 When the measurement time has elapsed and the measurement of the electrical characteristics of the component s is completed, themover 36 is moved backward by the control of the electromagnetic valve device 72 in S7. When the retracted end is reached, the mover position sensor 118 is turned on. In S8, the holding base 32 is moved backward by the control of the electromagnetic valve device 69 {FIG. 9 (d)}. The stroke until the holding base 32 comes into contact with the stopper 82 of the mover 36 at the retracted end position from the measurement state is L1. Therefore, it can be seen that the holding base 32 has come into contact with the stopper 82 after the backward movement time Tb, which is the time required for the backward movement of the stroke L1, has elapsed. As shown in FIG. 9D, the holding base 32 is located behind the facing surface 36f of the mover 36, and does not exist below the pair of facing surfaces 34f, 36f. This state is a discarding state.
When the holdingbase 32 is retracted until it comes into contact with the stopper 82, the air chamber 64 b is communicated with the air source 68 in the air cylinder 64 and the air chamber 64 a is connected to the air passage 60 in S 9 under the control of the electromagnetic valve device 69. Communicated. When the holding table 32 is advanced and hits the stopper 80, the holding table position sensor 120 is turned on. The holding table 32 is located between the pair of facing surfaces 34f and 36f (the V groove 44 is located below the facing surfaces 34f and 36f), and the space above the V groove 44c is a space. Therefore, the component s can be placed. This state is the initial state.
保持台32がストッパ82に当接するまで後退させられると、S9において、電磁弁装置69の制御により、エアシリンダ64においてエア室64bがエア源68に連通させられ、エア室64aがエア通路60に連通させられる。保持台32が前進させられ、ストッパ80に当たると保持台位置センサ120がONとなる。保持台32は、一対の対向面34f、36fの間に位置し(V溝44が対向面34f、36fの間の下方に位置し)、V溝44cの上方が空間とされている。そのため、部品sが載置可能とされる。この状態が初期状態である。 When the measurement time has elapsed and the measurement of the electrical characteristics of the component s is completed, the

可動子36の対向面36fが固定子34の対向面34fから離間することにより、これらの間に把持されていた部品sが開放される。また、可動子36の後退時には、エアシリンダ70のエア室70aがエア通路60に連通させられ、カバー用板部52,54は、それぞれ、一対の対向面34f、36fの間の空間のx方向の両側に位置する。さらに、保持台32が可動子36の対向面36fの後方に移動させられることにより、一対の対向面34f、36fの間の下方に存在しなくなり、一対の対向面34f、36fの間は、開口29a、30a、廃棄通路28に連通させられる。
可動子36の後退に伴って、エア室70aから流出させられたエアが開口60aから可動子36の対向面36fに斜め上方から供給されるが、エアが供給される空間、換言すれば、一対の対向面34f、36fの間の空間が、カバー部50によってx方向から覆われる。エアは、主として対向面36fに当たった後、対向面36fに沿って下方へ流れる。そのため、仮に、対向面36fから部品sが落下せず、部分Rに付着していても、それを良好に落下させることができる。また、エアは、カバー部50の内部を渦状に流れるため、仮に、固定子34の対向面34fに部品sが付着していたとしても落下させることができる。さらに、対向面34f、36fから落下して保持台32の上に載った部品sもエアにより落下させ得るが、仮に、V溝44上に部品sが載って、エアにより落下しなかった場合であっても、保持台32の後退に伴う可動子36の対向面36fの前進により確実に落下させることができる。このように、本実施例において、廃棄状態は、部品sが良好に落下させられた状態と考えることができる。
なお、一対の対向面34f、36fから落下した部品sは、開口29a、30a、廃棄通路28を経て良好にごみ箱26へ収容される。 When the facingsurface 36f of the mover 36 is separated from the facing surface 34f of the stator 34, the component s held between them is released. Further, when the mover 36 is retracted, the air chamber 70a of the air cylinder 70 is communicated with the air passage 60, and the cover plate portions 52 and 54 are respectively in the x direction of the space between the pair of facing surfaces 34f and 36f. Located on both sides. Further, when the holding base 32 is moved to the rear of the facing surface 36f of the mover 36, it does not exist below between the pair of facing surfaces 34f, 36f, and the space between the pair of facing surfaces 34f, 36f is an opening. 29a, 30a and the waste passage 28 are communicated.
As themover 36 moves backward, the air that has flowed out of the air chamber 70a is supplied from the opening 60a to the opposing surface 36f of the mover 36 obliquely from above. The space between the opposing surfaces 34f, 36f is covered by the cover portion 50 from the x direction. The air mainly hits the facing surface 36f and then flows downward along the facing surface 36f. Therefore, even if the component s does not fall from the facing surface 36f and adheres to the portion R, it can be dropped well. Further, since the air flows in a spiral shape inside the cover portion 50, even if the component s is attached to the facing surface 34f of the stator 34, the air can be dropped. Further, the component s dropped from the opposing surfaces 34f and 36f and placed on the holding table 32 can also be dropped by air. However, in the case where the component s is placed on the V groove 44 and does not fall by air. Even if it exists, it can fall reliably by advance of the opposing surface 36f of the needle | mover 36 accompanying retreat of the holding stand 32. Thus, in the present embodiment, the discarding state can be considered as a state in which the component s has been dropped well.
The component s dropped from the pair of opposed surfaces 34f and 36f is satisfactorily accommodated in the trash box 26 through the openings 29a and 30a and the disposal passage 28.
可動子36の後退に伴って、エア室70aから流出させられたエアが開口60aから可動子36の対向面36fに斜め上方から供給されるが、エアが供給される空間、換言すれば、一対の対向面34f、36fの間の空間が、カバー部50によってx方向から覆われる。エアは、主として対向面36fに当たった後、対向面36fに沿って下方へ流れる。そのため、仮に、対向面36fから部品sが落下せず、部分Rに付着していても、それを良好に落下させることができる。また、エアは、カバー部50の内部を渦状に流れるため、仮に、固定子34の対向面34fに部品sが付着していたとしても落下させることができる。さらに、対向面34f、36fから落下して保持台32の上に載った部品sもエアにより落下させ得るが、仮に、V溝44上に部品sが載って、エアにより落下しなかった場合であっても、保持台32の後退に伴う可動子36の対向面36fの前進により確実に落下させることができる。このように、本実施例において、廃棄状態は、部品sが良好に落下させられた状態と考えることができる。
なお、一対の対向面34f、36fから落下した部品sは、開口29a、30a、廃棄通路28を経て良好にごみ箱26へ収容される。 When the facing

また、カバー部50を設けることにより、落下した部品sが飛び散らないようにすることもできる。カバー用板部52の側板部52c、カバー用板部54の下端部は本体29の開口29aの近傍まで伸びているため、部品sを良好に開口29aから廃棄通路28を経てごみ箱26へ収容させることができる。一方、イオン化されたエアが供給される場合には可動子36、固定子34の対向面36f、34fを電気的に中和させることが可能となり、次の部品sの電気的特性の測定精度を向上させることができる。
さらに、エアシリンダ64において、保持台32の前進時(S9)にエア室64aがエア噴出通路60sに連通させられる。廃棄状態から初期状態へ移行する場合にも、可動子36の対向面36fにエアを供給することができるのであり、可動子36の対向面36fの除電を良好に行うことが可能となる。 Further, by providing thecover portion 50, it is possible to prevent the dropped component s from scattering. Since the side plate portion 52c of the cover plate portion 52 and the lower end portion of the cover plate portion 54 extend to the vicinity of the opening 29a of the main body 29, the component s is satisfactorily accommodated in the trash box 26 from the opening 29a through the disposal passage 28. be able to. On the other hand, when ionized air is supplied, the opposing surfaces 36f and 34f of the mover 36 and the stator 34 can be electrically neutralized, and the measurement accuracy of the electrical characteristics of the next component s can be improved. Can be improved.
Further, in theair cylinder 64, the air chamber 64a communicates with the air ejection passage 60s when the holding table 32 moves forward (S9). Even when the state is shifted from the discarding state to the initial state, air can be supplied to the facing surface 36f of the movable element 36, so that the charge removal of the facing surface 36f of the movable element 36 can be performed satisfactorily.
さらに、エアシリンダ64において、保持台32の前進時(S9)にエア室64aがエア噴出通路60sに連通させられる。廃棄状態から初期状態へ移行する場合にも、可動子36の対向面36fにエアを供給することができるのであり、可動子36の対向面36fの除電を良好に行うことが可能となる。 Further, by providing the

以上のように、本実施例においては、部品載置部44が導電性を有する材料で製造されるとともに接地される。その結果、電気的特性の測定前に部品載置部44に載せられた部品sの除電を良好に行うことができる。一方、部品sが帯電していると、部品sのインピーダンスを測定することが困難であった。それに対して、本実施例においては、部品sの除電が良好に行われるため、部品sのインピーダンスを良好に測定することができる。
さらに、可動子36の後退と並行して部品sを廃棄通路28に落下させることができるのであり、可動子の後退と、部品sの送出とを別の工程で行われる場合に比較して、電気的特性の測定に要する時間を短くすることができる。 As described above, in this embodiment, thecomponent mounting portion 44 is manufactured with a conductive material and is grounded. As a result, it is possible to satisfactorily remove the component s placed on the component placement unit 44 before measuring the electrical characteristics. On the other hand, when the component s is charged, it is difficult to measure the impedance of the component s. On the other hand, in this embodiment, since the charge removal of the component s is performed well, the impedance of the component s can be measured well.
Further, the part s can be dropped into thedisposal passage 28 in parallel with the retreat of the mover 36. Compared to the case where the retreat of the mover and the delivery of the part s are performed in separate steps, The time required for measuring the electrical characteristics can be shortened.
さらに、可動子36の後退と並行して部品sを廃棄通路28に落下させることができるのであり、可動子の後退と、部品sの送出とを別の工程で行われる場合に比較して、電気的特性の測定に要する時間を短くすることができる。 As described above, in this embodiment, the

さらに、永久磁石130の磁力により、部品sの両端の電極がV溝44cに引き寄せられるため、部品sが静電気によって吸着ノズル18に貼り付くことによる部品の姿勢の乱れが低減される。そのため、部品sは、部品sの両端の電極が一対の測定子37の各々に対向する向きで保持される。
Furthermore, since the electrodes at both ends of the component s are attracted to the V-groove 44c by the magnetic force of the permanent magnet 130, disturbance of the posture of the component due to the component s sticking to the suction nozzle 18 due to static electricity is reduced. Therefore, the component s is held in such a direction that the electrodes at both ends of the component s face each of the pair of measuring elements 37.

なお、一対の測定子の両方を移動可能とし、保持台を本体に固定とすることもできる。その場合であっても、保持台上に載せられた部品sを一対の測定子が把持し、一対の測定子が移動させられることにより、部品sから保持台を設定値以上離間させることができる。
また、保持台は、上下方向へ移動可能とすることもできる。その場合であっても、部品sが一対の測定子によってクランプされた状態で、保持台を部品sから設定値以上離間させることができる。
さらに、エア噴出通路を検査装置22の本体29の側部に、概してx方向に開く開口を有する状態で設けることもできる。換言すれば、カバー用板部52,54のいずれか一方をなくし(例えば、カバー用板部54をなくし)、そのなくした側に、x方向に開口を有するエア噴出通路を設けることができる。その結果、エアは、対向面34f、36f(xz方向に伸びた面)に沿って、カバー用板部52に向かって供給されることになり、それにより、一対の対向面34f、36fに付着した部品sを落とすことが可能となる。
また、部品sの電気的特性の測定後に、保持台32を可動子36の後退に伴って後退させる(例えば、同時に後退させる)ことも可能である。この保持台32および可動子36が後退させられる状態を廃棄状態とすることもできる。
さらに、可動子位置センサ118、保持台位置センサ120は不可欠ではない。例えば、タイマ124による計測により電磁弁装置69,72を制御することもできる。また、エア供給装置も不可欠ではない。 In addition, both of a pair of measuring elements can be moved, and a holding stand can also be fixed to a main body. Even in such a case, the pair of measuring elements grips the component s placed on the holding table, and the pair of measuring elements are moved, so that the holding table can be separated from the component s by a set value or more. .
Further, the holding table can be moved in the vertical direction. Even in this case, the holding base can be separated from the component s by a set value or more in a state where the component s is clamped by the pair of measuring elements.
Further, the air ejection passage may be provided in the side portion of themain body 29 of the inspection device 22 in a state having an opening that generally opens in the x direction. In other words, one of the cover plate portions 52 and 54 can be eliminated (for example, the cover plate portion 54 can be eliminated), and an air ejection passage having an opening in the x direction can be provided on the missing side. As a result, the air is supplied toward the cover plate portion 52 along the opposing surfaces 34f and 36f (surfaces extending in the xz direction), thereby adhering to the pair of opposing surfaces 34f and 36f. It is possible to drop the parts s.
In addition, after the measurement of the electrical characteristics of the component s, the holdingbase 32 can be retracted (for example, simultaneously retracted) as the mover 36 is retracted. The state in which the holding table 32 and the mover 36 are retracted can be set as a discarding state.
Further, themover position sensor 118 and the holding stand position sensor 120 are not essential. For example, the electromagnetic valve devices 69 and 72 can be controlled by measurement by the timer 124. Also, an air supply device is not essential.
また、保持台は、上下方向へ移動可能とすることもできる。その場合であっても、部品sが一対の測定子によってクランプされた状態で、保持台を部品sから設定値以上離間させることができる。
さらに、エア噴出通路を検査装置22の本体29の側部に、概してx方向に開く開口を有する状態で設けることもできる。換言すれば、カバー用板部52,54のいずれか一方をなくし(例えば、カバー用板部54をなくし)、そのなくした側に、x方向に開口を有するエア噴出通路を設けることができる。その結果、エアは、対向面34f、36f(xz方向に伸びた面)に沿って、カバー用板部52に向かって供給されることになり、それにより、一対の対向面34f、36fに付着した部品sを落とすことが可能となる。
また、部品sの電気的特性の測定後に、保持台32を可動子36の後退に伴って後退させる(例えば、同時に後退させる)ことも可能である。この保持台32および可動子36が後退させられる状態を廃棄状態とすることもできる。
さらに、可動子位置センサ118、保持台位置センサ120は不可欠ではない。例えば、タイマ124による計測により電磁弁装置69,72を制御することもできる。また、エア供給装置も不可欠ではない。 In addition, both of a pair of measuring elements can be moved, and a holding stand can also be fixed to a main body. Even in such a case, the pair of measuring elements grips the component s placed on the holding table, and the pair of measuring elements are moved, so that the holding table can be separated from the component s by a set value or more. .
Further, the holding table can be moved in the vertical direction. Even in this case, the holding base can be separated from the component s by a set value or more in a state where the component s is clamped by the pair of measuring elements.

引き寄せ部として、永久磁石の代わりに、電磁石を利用してもよい。また、引き寄せ部として、例えばエアの吸引などによる負圧力を用いた引き寄せ機構を利用してもよい。引き寄せ部として、電磁石や負圧力を用いる場合、吸着ノズル18が部品sをV溝44cに載置する際には、磁力や負圧力をONにし、一対の測定子37による部品sのクランプ以降の工程では、磁力や負圧力をOFFにしたり、部品sのV溝44cへの載置時よりも弱い力を発生させたりして、引き寄せ力を変化させてもよい。
As an attracting part, an electromagnet may be used instead of a permanent magnet. Moreover, you may utilize the attraction | suction mechanism using the negative pressure by the attraction | suction of air etc. as an attraction part, for example. When an electromagnet or negative pressure is used as the drawing portion, when the suction nozzle 18 places the component s in the V-groove 44c, the magnetic force or negative pressure is turned on, and after the clamping of the component s by the pair of measuring elements 37, In the process, the pulling force may be changed by turning off the magnetic force or the negative pressure or generating a weaker force than when the component s is placed on the V groove 44c.
なお、引き寄せ部により測定エラーの発生を低減させる効果は、V溝44cが完全なV字であっても達成される。
It should be noted that the effect of reducing the occurrence of measurement errors by the drawing portion can be achieved even if the V groove 44c is a complete V-shape.
ところで、検査装置22は、様々な寸法の部品sの電気的特性を測定する。寸法が比較的小さく、重量が比較的軽い部品sは、静電気による吸着ノズル18への貼り付きやその他の要因により、部品載置部44上での部品sの姿勢が特に乱れ易い。
Incidentally, the inspection device 22 measures the electrical characteristics of the parts s having various dimensions. The component s having a relatively small size and a relatively light weight is particularly likely to be disturbed by the posture of the component s on the component placement unit 44 due to sticking to the suction nozzle 18 due to static electricity or other factors.
そのため、検査装置22の底部442のx方向の寸法は、様々な寸法の測定対象部品sのうちの、特定の部品sの一対の電極をy方向に並ばせた際の特定の部品sのx方向の寸法よりも大きくされている。また、検査装置22の底部442のx方向の寸法は、特定の部品sの一対の電極をx方向に並ばせた際の特定の部品sのx方向の寸法よりも小さくされている。
Therefore, the dimension in the x direction of the bottom 442 of the inspection device 22 is the x of the specific part s when the pair of electrodes of the specific part s are arranged in the y direction among the measurement target parts s of various dimensions. It is larger than the dimension in the direction. In addition, the dimension in the x direction of the bottom portion 442 of the inspection device 22 is smaller than the dimension in the x direction of the specific component s when the pair of electrodes of the specific component s are arranged in the x direction.
特定の部品sとは、寸法が小さく、重量が軽いため、姿勢の乱れが特に著しい部品である。例えば、測定対象部品sのうち、最も寸法が小さい部品sである。
Specified parts s are parts that are particularly remarkably disturbed in posture due to their small dimensions and light weight. For example, the part s having the smallest dimension among the parts s to be measured.
特定の部品sの一対の電極がy方向に並んだ状態で底部442に載置されれば、特定の部品sの底面のほぼ全面が、底部442上に接触できる。そのため、特定の部品sの底面と底部442との摩擦力により、特定の部品sの姿勢の乱れ、特に、特定の部品sの一対の電極がx方向に並ぶ方向に回転することを抑制できる。したがって、部品sの電気的特性の測定エラーの発生が低減される。
If the pair of electrodes of the specific component s are placed on the bottom 442 in a state of being aligned in the y direction, almost the entire bottom surface of the specific component s can contact the bottom 442. Therefore, the frictional force between the bottom surface and the bottom portion 442 of the specific component s can suppress the disorder of the posture of the specific component s, in particular, the rotation of the pair of electrodes of the specific component s in the direction aligned in the x direction. Therefore, the occurrence of measurement errors in the electrical characteristics of the component s is reduced.
なお、特定の部品sの底面と底部442との摩擦力により、特定の部品sの姿勢の乱れを低減させる効果は、少なくとも、底部442のx方向の寸法が、特定の部品sの一対の電極をy方向に並ばせた際の特定の部品sのx方向の寸法よりも大きければよい。底部442のx方向の寸法が、特定の部品sの一対の電極をx方向に並ばせた際の特定の部品sのx方向の寸法よりも小さいことは不可欠ではない。しかし、底部442のx方向の寸法が、特定の部品sの一対の電極をx方向に並ばせた際の特定の部品sのx方向の寸法よりも小さければ、傾斜面441L、441Rにより、両端の電極が一対の測定子37の各々に対向する向きで吸着ノズル18に保持された特定の部品sが底部442に載置された後に、特定の部品sの一対の電極がx方向に並ぶ方向に回転することをさらに抑制できる。
The effect of reducing the disorder of the posture of the specific part s by the frictional force between the bottom surface and the bottom part 442 of the specific part s is that at least the dimension in the x direction of the bottom part 442 is a pair of electrodes of the specific part s. It suffices if it is larger than the dimension in the x direction of the specific component s when the are aligned in the y direction. It is not essential that the dimension in the x direction of the bottom portion 442 is smaller than the dimension in the x direction of the specific part s when the pair of electrodes of the specific part s are arranged in the x direction. However, if the dimension in the x direction of the bottom portion 442 is smaller than the dimension in the x direction of the specific component s when the pair of electrodes of the specific component s are arranged in the x direction, the inclined surfaces 441L and 441R A direction in which the pair of electrodes of the specific component s are arranged in the x direction after the specific component s held by the suction nozzle 18 is placed on the bottom portion 442 so that the electrodes of Can be further suppressed.
部品sが比較的大きな寸法の部品、すなわち、一対の電極がy方向に並んだ状態の部品sのx方向の寸法が、底部442のx方向の寸法よりも大きい部品sを測定する場合、吸着ノズル18に保持された部品sがV溝44cに載置されると、部品sは底部442上に載置できない寸法である。しかし、上方へ向かうにつれて互いに離間する一対の傾斜面441L、441Rにより、底部442上に載置できない寸法の部品sをV溝44cに載置することができる。部品sは図12または図13のような姿勢となる。部品sが図12のような姿勢となった場合、部品sを構成する面が水平面に対して傾斜した状態で部品sが載置された状態となるが、部品sと傾斜面441Lとの接触面積が大きいことや、部品sの重量が比較的重いことなどの理由により、図12の姿勢を維持し易い。部品sが図13のような姿勢となった場合、部品sとV溝44cとの接触面積は小さいが、部品sの重量が比較的重いため、図13の姿勢を維持し易い。したがって、一対の電極がy方向に並んだ状態の部品sのx方向の寸法が、底部442のx方向の寸法よりも大きい部品sであっても、吸着ノズル18によりV溝44cに載置された姿勢から、部品sの一対の電極がx方向に並ぶ方向に回転する可能性は、特定の部品sより少ない。
When the part s is a part having a relatively large dimension, that is, when the part s in which the pair of electrodes are arranged in the y direction has a dimension in the x direction larger than the dimension in the x direction of the bottom part 442, the suction is performed. When the component s held by the nozzle 18 is placed in the V-groove 44c, the component s has a size that cannot be placed on the bottom portion 442. However, the pair of inclined surfaces 441L and 441R that are separated from each other toward the upper side can place the component s having a size that cannot be placed on the bottom portion 442 in the V-groove 44c. The component s has a posture as shown in FIG. When the component s is in the posture as shown in FIG. 12, the component s is placed with the surface constituting the component s inclined with respect to the horizontal plane, but the component s and the inclined surface 441L are in contact with each other. The posture of FIG. 12 is easily maintained due to the large area and the relatively heavy weight of the component s. When the part s is in the posture as shown in FIG. 13, the contact area between the part s and the V-groove 44c is small, but the weight of the part s is relatively heavy, so that the posture of FIG. 13 can be easily maintained. Therefore, even if the dimension s in the x direction of the component s with the pair of electrodes arranged in the y direction is larger than the dimension s in the x direction of the bottom portion 442, the suction nozzle 18 places the component s in the V groove 44c. Therefore, the possibility that the pair of electrodes of the component s rotate in the direction aligned in the x direction is less than that of the specific component s.
以上のように、特定の部品sのV溝44cへの載置に着目した実施例において、部品載置部44が部品載置部に対応し、V溝44cが溝に対応し、y方向が第一方向に対応し、底部442が底部に対応し、傾斜面441L、441Rが一対の傾斜面に対応し、一対の測定子37が一対の測定子に対応する。また、x方向が第二方向に対応する。
As described above, in the embodiment focusing on the placement of the specific component s in the V groove 44c, the component placement portion 44 corresponds to the component placement portion, the V groove 44c corresponds to the groove, and the y direction is Corresponding to the first direction, the bottom 442 corresponds to the bottom, the inclined surfaces 441L and 441R correspond to a pair of inclined surfaces, and the pair of measuring elements 37 corresponds to a pair of measuring elements. The x direction corresponds to the second direction.
なお、部品載置部に底部を設けることにより測定エラーの発生を低減させる効果は、部品載置部の下方に引き寄せ部がなくても達成される。ただし、部品載置部の下方に引き寄せ部を設けることにより、測定エラーの発生を低減させる効果はさらに向上する。
It should be noted that the effect of reducing the occurrence of measurement errors by providing a bottom portion on the component placement portion can be achieved without a drawing portion below the component placement portion. However, the effect of reducing the occurrence of measurement errors is further improved by providing a drawing portion below the component placement portion.
