Abstract

<P>PROBLEM TO BE SOLVED: To provide making ink have a long life and simplification of maintenance of a screen printing squeegee. <P>SOLUTION: The squeegee 5 of a flat plate shape is bent in a U-shape and is held by a holder 6. Both ends of it are closed by side plates 8. Because an opening part is closed with a mask at the time of printing, no part of paste-like ink 4 is exposed to open air so that the life of the ink is extended. When the ink is changed and the screen printing squeegee is cleaned, the main body can be easily disassemlbed. Because a structure allowing only the squeegee 5, side plates 8 and the mask to get into contact with the ink is employed, the recovery of the ink, cleaning of the main body and change of the ink become very easy. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

発明の詳細な説明Detailed Description of the Invention

産業上の利用分野Industrial application fields

本発明は、スクリーン印刷機に関し、特に、スクリーン印刷装置により印刷する際にクリーム半田をメタルマスクの孔に押し込む機能を有するスキージ(へら)に関する。  The present invention relates to a screen printing machine, and more particularly, to a squeegee having a function of pushing cream solder into a hole of a metal mask when printing by a screen printing apparatus.

次に、従来の実施例について図面を参照しながら具体的に説明する。  Next, a conventional example will be specifically described with reference to the drawings.

図1は、従来の代表的な実施例を示す側面図である。  FIG. 1 is a side view showing a typical example of the prior art.

図1を参照するに、従来、この種のスクリーン印刷では、金属、又は樹脂製のシートに、印刷するパターン部分が開口された形状の版であるマスク3を、印刷対象物表面に被せ、版の表面に乗せたペースト状インク4(クリームハンダ等の金属ペースト等の場合もある)を、主にウレタン製で板形状のゴムスキージ1を、図1の矢印方向へ駆動することによって、マスク3の開口部分にペースト状インク4を押下し、印刷を行う。  Referring to FIG. 1, conventionally, in this type of screen printing, a mask 3 which is a plate having a shape in which a pattern portion to be printed is opened on a sheet made of metal or resin is placed on the surface of a printing object. The paste-like ink 4 (which may be a metal paste such as cream solder) placed on the surface of the mask 3 is driven by the urethane rubber plate-shaped rubber squeegee 1 in the direction of the arrow in FIG. Printing is performed by pressing the paste-like ink 4 in the opening.

発明が解決しようとする課題Problems to be solved by the invention

しかしながら、この従来の印刷方法は、ペースト状インクが直接外気に晒されており、その為にペーストインクの劣化が早い。従って、印刷条件を一定に長時間保つのが難しく、又、ペースト状インクの交換作業もインクが周りに広がる為、インクの清掃等に大変な手間がかかっていた。  However, in this conventional printing method, the paste-like ink is directly exposed to the outside air, so that the paste ink is rapidly deteriorated. Accordingly, it is difficult to keep the printing conditions constant for a long time, and the ink for the paste-like ink replacement work spreads around, so that it takes much time to clean the ink.

本発明は、従来の上記実状に鑑みてなされたものであり、従って本発明の目的は、従来の技術に内在する上記欠点を解消し、更に、従来のスクリーン印刷用スキージに比べて、印刷作業の手間を大幅に軽減するものである。  The present invention has been made in view of the above-described actual situation, and therefore, the object of the present invention is to eliminate the above-mentioned drawbacks inherent in the prior art, and further, compared with a conventional screen printing squeegee. This greatly reduces the time and effort.

課題を解決する為の手段Means to solve the problem

上記目的を解決する為に、本発明に係わるスクリーン印刷用スキージでは、スキージをU字型に曲げ、その回りをホルダーで包んでスキージのU字形状を保持し、その内側にペーストインクを封入し、更に、スキージの両端を側板で塞ぐことにより、ペーストインクを外気から遮断している。  In order to solve the above-described object, in the squeegee for screen printing according to the present invention, the squeegee is bent into a U shape, wrapped around a holder to hold the U shape of the squeegee, and paste ink is sealed inside. Further, the paste ink is blocked from the outside air by closing both ends of the squeegee with side plates.

そして従来では、ペーストインクがスキージ以外の部分にも付着しやすく、マスク上にも広がる為、定期的にインクを中央に寄せねばならず、又、インクの交換作業の際にも、広範囲を清掃する必要がある等、の問題があったが、本発明では、インクはスキージと、側板に囲まれた空間にのみ存在する為、清掃が容易であり、インクが周囲に広がる問題も解消している。  Conventionally, the paste ink easily adheres to parts other than the squeegee and spreads on the mask, so the ink must be periodically moved to the center, and a wide range of cleaning is performed during ink replacement work. However, in the present invention, since the ink exists only in the space surrounded by the squeegee and the side plate, cleaning is easy, and the problem that the ink spreads around is also solved. Yes.

これらは、従来のスクリーン印刷用スキージに比べ、大幅に作業者の手間を省けるものである。  These can greatly save the labor of the operator as compared with the conventional screen printing squeegee.

次に本発明をその好ましい各実施例について図面を参照しながら具体的に説明する。  Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

図2(a)、(b)は、本発明で使用されるスクリーン印刷用スキージ本体の正面図であり、(c)は、その側面図である。  2 (a) and 2 (b) are front views of a screen printing squeegee body used in the present invention, and FIG. 2 (c) is a side view thereof.

図3(a)は、本発明で使用されるスクリーン印刷用スキージ本体の斜視図であり、(b)は、その構成部品を示した分解斜視図である。  FIG. 3A is a perspective view of a screen printing squeegee body used in the present invention, and FIG. 3B is an exploded perspective view showing the components thereof.

図4(a)、(b)は、本発明で使用されるスクリーン印刷用スキージの、スキージと、ホルダーの組み立て方法を示した側面図である。  FIGS. 4A and 4B are side views showing a method of assembling the squeegee and holder of the screen printing squeegee used in the present invention.

図2(a)〜(c)と、図3(a)〜(b)、及び、図4(a)〜(b)を参照するに、本発明におけるスクリーン印刷用スキージ本体は、図4(a)に示した板状のスキージを図4(a)の矢印方向にU字に湾曲させた形状を持つスキージ5と、そのスキージ5を図4(b)の矢印方向に挟み込み、そのU字形状を保持するホルダー6と、スキージ5と、ホルダー6の両端に配設され、スキージ5のU字空間の両端を塞ぐ側板8と、スキージ5のU字空間に、ペースト状インク4を供給する、インク供給手段7で構成される。  Referring to FIGS. 2A to 2C, FIGS. 3A to 3B, and FIGS. 4A to 4B, the squeegee main body for screen printing according to the present invention is shown in FIG. A squeegee 5 having a shape in which the plate-like squeegee shown in a) is bent in a U-shape in the direction of the arrow in FIG. 4A, and the squeegee 5 is sandwiched in the direction of the arrow in FIG. The paste-like ink 4 is supplied to the holder 6 that holds the shape, the squeegee 5, the side plate 8 that is disposed at both ends of the holder 6 and closes both ends of the U-shaped space of the squeegee 5, and the U-shaped space of the squeegee 5. And an ink supply means 7.

図5は、本発明で使用されるスクリーン印刷用スキージの使用状態を示す部分断面図である。  FIG. 5 is a partial cross-sectional view showing a usage state of the screen printing squeegee used in the present invention.

図5を参照するに、本発明におけるスクリーン印刷用スキージでの印刷は、基本的に図1の従来の方法と同様に、スキージ本体10をマスク3に押し付け、図5の矢印方向に駆動して印刷を行う。  Referring to FIG. 5, printing with the squeegee for screen printing in the present invention is basically performed by pressing the squeegee body 10 against the mask 3 and driving it in the direction of the arrow in FIG. Print.

この際、スキージ5のU字空間には、ペースト状インク4が、インク供給手段7から、常に一定圧で供給され、この供給圧によって、ペースト状インク4は、スキージ5のU字空間の開口部13を通り、マスク3の開口部にペースト状インク4が押下され、印刷を行う。    At this time, the paste-like ink 4 is always supplied from the ink supply means 7 to the U-shaped space of the squeegee 5 at a constant pressure, and the paste-like ink 4 is opened in the U-shaped space of the squeegee 5 by this supply pressure. The paste-like ink 4 is pressed through the portion 13 to the opening of the mask 3 to perform printing.

インク供給手段7は、モーター、エアー等、インクの加圧方法は特に限定しない。  The ink supply means 7 is not particularly limited in the method of pressurizing ink, such as a motor or air.

又、図2(a)〜(b)に示すようにインク供給手段7は、側版8の片方、又は両方、いずれの状態でも使用可能であり、取り付け個所も、側板8には限定されず、スキージ5のU字空間にインクが供給出来れば、どこに取り付けても良い。  Further, as shown in FIGS. 2A and 2B, the ink supply means 7 can be used in one or both of the side plates 8, and the mounting location is not limited to the side plate 8. As long as ink can be supplied to the U-shaped space of the squeegee 5, it may be installed anywhere.

尚、図1、及び図2のスキージを図の矢印方向に移動する機構が実際には必要であるが、特に図示しない。  A mechanism for moving the squeegee of FIGS. 1 and 2 in the direction of the arrow in the drawing is actually required, but is not particularly illustrated.

又、スキージ5のU字空間は、マスク3と、側板8に囲まれ、密閉空間を形成する事により、外気とペースト状インク4を隔離し、ペースト状インク4が外気に触れる事で発生するインクの劣化を防いでいる。  Further, the U-shaped space of the squeegee 5 is surrounded by the mask 3 and the side plate 8 to form a sealed space, thereby separating the outside air from the paste-like ink 4 and being generated when the paste-like ink 4 is exposed to the outside air. Ink deterioration is prevented.

更に、ペースト状インク4は、基本的にスキージ5と、側板8、マスク3一部にしか触れず、インクの交換、清掃の際には、ホルダー6からスキージ5と、側板8を取り外し、簡単に清掃する事が出来る。しかも、スキージ5は、ホルダー6から取り外すと、平面形状にする事が出来る為、更にインクの回収、清掃が従来のスキージに比べ大幅に簡単な作業になる。  Further, the paste-like ink 4 basically touches only a part of the squeegee 5, the side plate 8, and the mask 3, and when changing or cleaning the ink, the squeegee 5 and the side plate 8 are removed from the holder 6, so Can be cleaned. Moreover, since the squeegee 5 can be formed into a flat shape when it is removed from the holder 6, the ink collection and cleaning are much easier than conventional squeegees.
