And a suction part provided at the tip, and the rear end of the handle part is connectable to an external suction force generation source.

本発明によれば、プリント基板の切断加工時等において発生する粉塵を、収容部に残らないように且つ飛散させることなく外部に排出させることが可能となる。   ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to discharge the dust which generate | occur | produces at the time of the cutting process of a printed circuit board, etc. without leaving in an accommodating part and without scattering.

以下、図面を参照して、本発明の実施の形態について詳しく説明する。図１は、プリント基板の切断装置１の例を示す概略図である。図２は、そのプリント基板の切断装置１の集塵機構２の例を示す概略図である。図３は、本発明の実施の形態に係る集塵トレイ１０の例を示す概略図である。図４は、その集塵トレイ１０の吸引部１５について開口部１６側から視た拡大図である。図５は、その集塵トレイ１０を取手部１４の挿通方向に切断した断面図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an example of a printed circuit board cutting apparatus 1. FIG. 2 is a schematic diagram illustrating an example of the dust collection mechanism 2 of the printed circuit board cutting device 1. FIG. 3 is a schematic view showing an example of the dust collection tray 10 according to the embodiment of the present invention. FIG. 4 is an enlarged view of the suction portion 15 of the dust collection tray 10 as viewed from the opening 16 side. FIG. 5 is a cross-sectional view of the dust collection tray 10 cut in the insertion direction of the handle portion 14.

図１に示すプリント基板の切断装置１は、被加工物である平板形状のプリント基板２と略平行な面内を移動自在に設けられ回転軸の先端部に刃が形成されたルータビット３を用いて、プリント基板２を所定の切断線に沿って切断する切断装置であり、プリント基板２の切断位置から発生する粉塵（切削片）を吸引により収集する集塵機構４を備える。   A printed circuit board cutting apparatus 1 shown in FIG. 1 includes a router bit 3 that is movably provided in a plane substantially parallel to a flat plate-shaped printed circuit board 2 that is a workpiece and has a blade formed at the tip of a rotating shaft. A cutting device that cuts the printed circuit board 2 along a predetermined cutting line, and includes a dust collection mechanism 4 that collects dust (cut pieces) generated from the cutting position of the printed circuit board 2 by suction.

図２に示す集塵機構４は、吸引ポンプ（不図示）が組み込まれた本体５と、この本体５に一端が取り付けられ、他端に漏斗状に開口する集塵ノズル６が設けられたホース７と、集めた粉塵を収容する集塵トレイ１０とを備える。
プリント基板２の切断時には、吸引ポンプを作動させることによって、切断ポイントから発生する粉塵８が、集塵ノズル６により吸引され、ホース７内を通過して本体５内へと移動し、フィルタ等（不図示）でトラップされた後、ふるい落とされて、集塵トレイ１０に集められて収容される。 A dust collection mechanism 4 shown in FIG. 2 includes a main body 5 in which a suction pump (not shown) is incorporated, and a hose 7 having one end attached to the main body 5 and provided with a dust collection nozzle 6 opening in a funnel shape at the other end. And a dust collection tray 10 for storing the collected dust.
When the printed circuit board 2 is cut, by operating the suction pump, the dust 8 generated from the cutting point is sucked by the dust collecting nozzle 6 and passes through the hose 7 and moves into the main body 5 to be filtered, etc. After being trapped in (not shown), it is screened off and collected and stored in the dust collection tray 10.

ここで、従来の集塵トレイ５０を図６（ｂ）に示す。なお、図６（ａ）は、集塵トレイ５０が集塵機構４にセットされた状態の図である。
従来の集塵トレイ５０は、当該図６（ｂ）のように、単なる箱型の引出状の構成であった。したがって、収容部５１に収容された粉塵を清掃しようとする場合には、集塵トレイ５０を引き出して、直接、掃除機によって吸引して除去を行っていた。
しかし、集塵トレイ５０を引き出した際に、粉塵８が舞い上がり、飛散するため、人体に害を及ぼす可能性があり、また周囲の環境を汚損する原因にもなっていた。 Here, the conventional dust collection tray 50 is shown in FIG.6 (b). FIG. 6A is a diagram showing a state in which the dust collection tray 50 is set in the dust collection mechanism 4.
The conventional dust collection tray 50 has a simple box-shaped drawer configuration as shown in FIG. Therefore, when the dust stored in the storage portion 51 is to be cleaned, the dust collection tray 50 is pulled out and directly removed by suction with a vacuum cleaner.
However, when the dust collection tray 50 is pulled out, the dust 8 rises and scatters, which may cause harm to the human body and also cause the surrounding environment to be polluted.

続いて、本実施の形態に係る集塵トレイ１０を、図３の拡大図に示す。なお、本実施の形態に係る集塵トレイ１０は、同様の構成を備える集塵トレイ１０Ａと、集塵トレイ１０Ｂとを並設する構成である。   Then, the dust collection tray 10 which concerns on this Embodiment is shown in the enlarged view of FIG. In addition, the dust collection tray 10 which concerns on this Embodiment is a structure which arranges the dust collection tray 10A provided with the same structure, and the dust collection tray 10B in parallel.

符号１１は収容部である。矩形状の底面１２と、該底面の四辺から立設する周壁１３とを有し、底面１２上に粉塵８を載置して収容することが可能である。   Reference numeral 11 denotes an accommodating portion. It has a rectangular bottom surface 12 and a peripheral wall 13 erected from four sides of the bottom surface, and the dust 8 can be placed on the bottom surface 12 and accommodated.

符号１４は取手部である。取手部１４は内部に管路を有する管状構造であって、収容部１１の一つの周壁１３を挿通すると共に当該挿通方向（図中の矢印Ｘの方向であり、以下「Ｘ方向」という）に移動可能に設けられる。なお、挿通箇所にはパッキン（不図示）等を配して、隙間が生じないように構成することが粉塵の飛散防止の観点で好適である。
取手部１４の後端１４Ｂにはホース連結部１９が設けられて、例えば掃除機等の吸引力発生源（不図示）に連通するホース２１と、当該ホース連結部１９とが連結・取り外し自在に接続される。なお、ホース２１が連結されていないときには、ホース連結部１９にキャップ２２を嵌めて、粉塵８の飛散を防止する。
この構成により、吸引力発生源を動作させることによって発生する吸引力を、ホース２１を介して取手部１４に発生させる作用が生じる。 Reference numeral 14 denotes a handle portion. The handle portion 14 has a tubular structure having a pipe line therein, and is inserted through one peripheral wall 13 of the housing portion 11 and in the insertion direction (the direction of the arrow X in the figure, hereinafter referred to as “X direction”). It is provided so as to be movable. In addition, it is suitable from a viewpoint of preventing dust scattering that a packing (not shown) or the like is provided at the insertion portion so that no gap is generated.
A hose connecting portion 19 is provided at the rear end 14B of the handle portion 14 so that the hose 21 communicating with a suction force generation source (not shown) such as a vacuum cleaner and the hose connecting portion 19 can be connected and detached. Connected. When the hose 21 is not connected, the cap 22 is fitted to the hose connecting part 19 to prevent the dust 8 from scattering.
With this configuration, there is an effect of causing the handle portion 14 to generate a suction force generated by operating the suction force generation source via the hose 21.

符号１５は吸引部である。吸引部１５には、取手部１４の挿通方向と直交方向（図中の矢印Ｙの方向であり、以下「Ｙ方向」という）に長孔状の開口部１６が設けられる。当該吸引部１５は、開口部１６から取手部１４の管路に連通する粉塵通過路（図５中の破線矢印）が形成されるように、取手部１４の先端１４Ａに接続される。
この構成により、吸引力発生源の動作により取手部１４に発生する吸引力を、吸引部１５の開口部１６に発生させる作用が生じ、開口部１６から粉塵８を吸引することが可能となる。また、その作用を生じさせている状態のまま、取手部１４をＸ方向に移動させると、それに伴って吸引部１５を収容部１１内でＸ方向に移動させることが可能となる。
すなわち、集塵トレイ１０を、集塵機構４に密閉状態で取り付けたまま引き出すことなく、収容部１１内の粉塵８を吸引部１５で吸引して、取手部１４内を通過させて集塵トレイ１０の外部へ排出することが可能となる。 Reference numeral 15 denotes a suction part. The suction portion 15 is provided with an opening 16 having a long hole shape in a direction orthogonal to the insertion direction of the handle portion 14 (in the direction of arrow Y in the drawing, hereinafter referred to as “Y direction”). The suction part 15 is connected to the tip 14A of the handle part 14 so that a dust passage (a broken line arrow in FIG. 5) communicating from the opening 16 to the pipe line of the handle part 14 is formed.
With this configuration, an action of generating the suction force generated in the handle portion 14 by the operation of the suction force generation source in the opening portion 16 of the suction portion 15 is generated, and the dust 8 can be sucked from the opening portion 16. Further, when the handle portion 14 is moved in the X direction while the action is being generated, the suction portion 15 can be moved in the X direction in the accommodating portion 11 accordingly.
That is, without pulling out the dust collection tray 10 while being attached to the dust collection mechanism 4 in a sealed state, the dust 8 in the storage portion 11 is sucked by the suction portion 15 and passed through the handle portion 14 to be collected. It becomes possible to discharge to the outside.

ここで、開口部１６の形状および配置構造について説明する。図４は、吸引部１５を開口部１６側から視た図である。
本実施の形態では、開口部１６を長方形の長孔に形成している。このとき、当該長孔の長手方向（ここではＹ方向）の長さが、底面１２のＹ方向の幅と略同一となるように形成する。なお、「略同一」なる表現は、開口部１６の外郭形成部材の厚さ（数ｍｍ程度）、および周壁１３との隙間（数ｍｍ程度）を含めれば同一となる趣旨である。
上記形状の開口部１６を収容部１１の底面１２に対向させて配置する。このとき、底面１２に対向する開口部１６の面（すなわち吸引部１５の下面）と、底面１２との距離を粉塵８が通過可能な距離まで近接させて配置する。基板２の種類あるいは切断方法（カッタの種類）等によって、粉塵８の形状・大きさは異なるため、適切な距離に設定すればよい。このような近接配置によって、開口部１６に向かって吸引される空気の流速を上げることができ、粉塵８の吸引力が向上する。ただし、当該距離が、あまりに狭いと粉塵８が通過できないため開口部１６まで到達できず、逆に、あまりに広いと粉塵８が吸引されない。
一例として、樹脂製のプリント基板２をルータビットで切断した場合に発生する粉塵（切削片）に対しては、吸引部１５の下面と底面１２との距離を２ｍｍ程度に設定すると好適である。
このように、開口部１６のＹ方向の幅が底面１２のＹ方向の幅と略同一であって、且つ前記の通り、開口部１６がＸ方向に移動可能である構成によって、開口部１６の面積を底面１２の面積よりも小さく形成する構成を実現しつつ、当該開口部１６に生じる吸引力を底面１２上の全ての場所に作用させることが可能となる。これにより、収容部１１内（底面１２上）に粉塵８が排出されないまま残されてしまうことを防止できる。
さらに、開口部１６の面積をより小さくできることは、吸引力をより大きくする効果を奏するため、粉塵８を除去する能力が向上する。逆の観点に立てば、大きな吸引力を発生させるための大型の吸引力発生源が不要となるため、吸引部１５自体の小型化と相俟って、製造コストの低減効果も奏される。 Here, the shape and arrangement structure of the opening 16 will be described. FIG. 4 is a view of the suction unit 15 as viewed from the opening 16 side.
In the present embodiment, the opening 16 is formed in a rectangular long hole. At this time, the long hole is formed such that the length in the longitudinal direction (here, the Y direction) is substantially the same as the width of the bottom surface 12 in the Y direction. Note that the expression “substantially identical” is the same as including the thickness (about several millimeters) of the outer shell forming member of the opening 16 and the gap (about several millimeters) with the peripheral wall 13.
The opening 16 having the above-described shape is disposed so as to face the bottom surface 12 of the accommodating portion 11. At this time, the distance between the surface of the opening 16 facing the bottom surface 12 (that is, the bottom surface of the suction portion 15) and the bottom surface 12 is set close to the distance through which the dust 8 can pass. Since the shape and size of the dust 8 differ depending on the type of the substrate 2 or the cutting method (type of cutter), etc., an appropriate distance may be set. Such close arrangement can increase the flow velocity of air sucked toward the opening 16 and improve the suction force of the dust 8. However, if the distance is too narrow, the dust 8 cannot pass and cannot reach the opening 16. Conversely, if the distance is too wide, the dust 8 is not sucked.
As an example, it is preferable to set the distance between the lower surface of the suction part 15 and the bottom surface 12 to about 2 mm for dust (cut pieces) generated when the resin printed board 2 is cut with a router bit.
As described above, the width of the opening 16 in the Y direction is substantially the same as the width of the bottom surface 12 in the Y direction, and the opening 16 can be moved in the X direction as described above. The suction force generated in the opening 16 can be applied to all locations on the bottom surface 12 while realizing a configuration in which the area is formed smaller than the area of the bottom surface 12. Thereby, it can prevent that the dust 8 is left in the accommodating part 11 (on the bottom face 12) without being discharged | emitted.
Furthermore, the ability to reduce the area of the opening 16 has the effect of increasing the suction force, so the ability to remove the dust 8 is improved. From the opposite point of view, a large suction force generation source for generating a large suction force is not necessary, and in combination with the downsizing of the suction part 15 itself, an effect of reducing the manufacturing cost is also achieved.

また、本実施の形態に特徴的な構成として、吸引部１５は、Ｘ方向における手前側および奥側に、長板状の掻き寄せ部１８を有する。本実施の形態では、吸引部１５の外枠を形成する部材として一体で形成される。すなわち、掻き寄せ部１８は、Ｙ方向に長板状であり、その長手方向の長さが底面１２のＹ方向の幅と略同一である。ここで、「略同一」なる表現は、周壁１３との隙間（数ｍｍ程度）を含めれば同一となる趣旨である。なお、掻き寄せ部１８を、吸引部１５と別体で形成しても構わない。
この構成により、吸引部１５のＸ方向の移動に伴い、収容部１１に収容された粉塵８が、掻き寄せ部１８によって押動されながら一定厚さにならされるため、開口部１６から吸引し易くなる効果が奏される。 In addition, as a characteristic configuration of the present embodiment, the suction unit 15 includes a long plate-like scraping unit 18 on the near side and the far side in the X direction. In the present embodiment, it is integrally formed as a member that forms the outer frame of the suction portion 15. That is, the scraping portion 18 has a long plate shape in the Y direction, and the length in the longitudinal direction is substantially the same as the width of the bottom surface 12 in the Y direction. Here, the expression “substantially identical” is the same as including the gap (about several mm) with the peripheral wall 13. Note that the scraping portion 18 may be formed separately from the suction portion 15.
With this configuration, as the suction part 15 moves in the X direction, the dust 8 accommodated in the accommodation part 11 is made to have a constant thickness while being pushed by the scraping part 18, and therefore is sucked from the opening 16. The effect which becomes easy is show | played.

また、本実施の形態に特徴的な構成として、図５に示すように、掻き寄せ部１８の板面が、収容部１１の底面１２に対して直角に形成されると共に、収容部１１の、Ｘ方向の手前側および奥側の周壁１３の内面が傾斜面（符号１３’）に形成される。傾斜形状は、底面１２から直交方向（図中上方）に離れるにつれて手前側の周壁１３の内面（すなわち傾斜面１３’）と、奥側の周壁１３の内面（すなわち傾斜面１３’）との間の距離が拡大するように傾斜させる。
なお、本実施の形態では、図５に示すように、周壁１３とは別部材を設けて傾斜面１３’を形成しているが、周壁１３を直接、傾斜させることによって傾斜面１３’を形成してもよい。
仮に、周壁１３が傾斜面でなく、底面１２に対して直角に形成されている場合には、吸引部１５のＸ方向の移動に伴い、粉塵８が掻き寄せ部１８によって押動された際に、当該粉塵８の材質によっては、周壁１３の壁面に付着して塊状化してしまう可能性があるが、上記の構成を備えることによって、掻き寄せ部１８と傾斜面１３’との間で粉塵８が挟み込まれることがないため、当該課題の解決が可能となる。 Further, as a characteristic configuration of the present embodiment, as shown in FIG. 5, the plate surface of the scraping portion 18 is formed at a right angle to the bottom surface 12 of the storage portion 11, and The inner surfaces of the peripheral wall 13 on the near side and the far side in the X direction are formed on an inclined surface (reference numeral 13 '). The inclined shape is between the inner surface of the peripheral wall 13 on the near side (that is, the inclined surface 13 ′) and the inner surface of the peripheral wall 13 on the back side (that is, the inclined surface 13 ′) as it moves away from the bottom surface 12 in the orthogonal direction (upward in the figure). Tilt to increase the distance.
In the present embodiment, as shown in FIG. 5, a member different from the peripheral wall 13 is provided to form the inclined surface 13 ′, but the inclined surface 13 ′ is formed by directly inclining the peripheral wall 13. May be.
If the peripheral wall 13 is not an inclined surface but is formed at a right angle to the bottom surface 12, when the dust 8 is pushed by the scraping portion 18 as the suction portion 15 moves in the X direction. Depending on the material of the dust 8, the dust 8 may adhere to the wall surface of the peripheral wall 13 and be agglomerated. However, by providing the above configuration, the dust 8 is between the scraping portion 18 and the inclined surface 13 ′. Since this is not sandwiched, the problem can be solved.

また、前述の通り、本実施の形態に係る集塵トレイ１０は、同様の構成を備える集塵トレイ１０Ａと、集塵トレイ１０Ｂとを並設する構成である（図３参照）。
このように、同様の構成を備える複数の集塵トレイをＹ方向に併設する構成とすれば、吸引力発生源の吸引力の限界によって開口部１６を大きく形成できない場合等において、各開口部１６を小さく形成する一方で、収容部１１が複数設けられて、底面１２の合計面積を広くすることが可能となる。すなわち、吸引力を低下させることなく、逆にいえば、吸引力発生源を大型化することなく、収容部１１を広く設けることが可能となり、粉塵８の収容可能面積の拡大、収容量の増大を図ることが可能となる。 Further, as described above, the dust collection tray 10 according to the present embodiment has a configuration in which the dust collection tray 10A having the same configuration and the dust collection tray 10B are arranged in parallel (see FIG. 3).
As described above, when a plurality of dust collection trays having the same configuration are provided in the Y direction, the openings 16 can be formed in a case where the openings 16 cannot be formed largely due to the limit of the suction force of the suction force generation source. Can be made small, and a plurality of accommodating portions 11 are provided, so that the total area of the bottom surface 12 can be increased. In other words, without reducing the suction force, on the contrary, without increasing the suction force generation source, the storage portion 11 can be provided widely, the dust 8 can be accommodated in an increased area, and the accommodation amount can be increased. Can be achieved.

以上説明した通り、本実施の形態に係る集塵トレイによれば、プリント基板の切断加工時等において発生して、収容部に収容される粉塵を、当該集塵トレイを引き出さずに収容部が密閉された状態のままで、収容部に残らないように且つ飛散させることなく外部に排出させることが可能となる。   As described above, according to the dust collection tray according to the present embodiment, the storage unit generates dust that is generated during cutting processing of the printed circuit board and the like and is stored in the storage unit without pulling out the dust collection tray. The sealed state can be discharged outside without being left in the accommodating portion and without being scattered.

なお、本発明について、複合プリント基板を複数のプリント基板にそれぞれ分割するプリント基板の切断装置を例にとり説明を行ったが、これに限定されるものではなく、樹脂あるいは金属材料の切断加工等を行う機械加工装置において発生する粉塵（切削片）を集めて収容する集塵機構の集塵トレイに適用できることはいうまでもない。   Although the present invention has been described with reference to an example of a printed circuit board cutting device that divides a composite printed circuit board into a plurality of printed circuit boards, the present invention is not limited to this, and a cutting process of a resin or a metal material is performed. Needless to say, the present invention can be applied to a dust collection tray of a dust collection mechanism that collects and stores dust (cut pieces) generated in a machining apparatus.
