そして、図１１に示すように前記の塗料層に電子部品３６の所定面を押し付け、所定量の塗料３５を電子部品３６の所定面に塗布するという構成となっていた。
【０００５】
【発明が解決しようとする課題】
しかしながら前記従来の塗料塗布装置においては、均一な厚みにかきとられた塗料３５はペイント槽３１の前後方向に一続きになっており、電子部品３６を押し付けた際、ペイント槽３１の前後方向には電子部品３６の下面の端から端まで塗料３５が塗布され、塗料３５を塗布した電子部品３６を積層すると、電子部品３６の下面の両端に付着した塗料３５がはみ出しやすく、電子部品３６の塗装品質低下を生じさせるとともに、電子部品３６の製品寸法不良が発生するという課題を有していた。
【０００６】
また、はみ出した塗料３５が装置に付着し、装置のメンテナンス性を悪化させるという課題があった。
【０００７】
本発明は前記従来の課題を解決しようとするものであり、電子部品の塗料塗布面からの塗料のはみ出しを少なくし、塗装品質の向上を図るとともに電子部品の製品寸法不良を低減し、設備のメンテナンス性を向上させる塗料塗布装置を提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
前記課題を解決するために本発明は、個々に分離された複数の筋状突起を平行して内側面に設けた塗料槽と、この塗料槽内の前記複数の筋状突起の一部よりなる上下動突起を上下移動自在とした塗料転写ブロックと、前記塗料槽に塗料を供給する塗料供給部と、前記筋状突起上に前記塗料の層を形成するスキージと、前記上下動突起上に被塗布体を保持する素子供給部とを備えた塗料塗布装置であって、前記上下動突起の水平表面積は、前記被塗布体の下面面積より小さくし、前記素子供給部に保持された被塗布体の下面にこの上下動突起を押し付けることにより、前記被塗布体の下面内側部に前記塗料を塗布する構成としたものであり、電子部品の塗料塗布面の内側部に、安定して均一量の塗料を塗布することができ、塗料塗布面からの塗料のはみ出しを無くすことができる。
【０００９】
【発明の実施の形態】
本発明の請求項１に記載の発明は、個々に分離された複数の筋状突起を平行して内側面に設けた塗料槽と、この塗料槽内の前記複数の筋状突起の一部よりなる上下動突起を上下移動自在とした塗料転写ブロックと、前記塗料槽に塗料を供給する塗料供給部と、前記筋状突起上に前記塗料の層を形成するスキージと、前記上下動突起上に被塗布体を保持する素子供給部とを備えた塗料塗布装置であって、前記上下動突起の水平表面積は、前記被塗布体の下面面積より小さくし、前記素子供給部に保持された被塗布体の下面にこの上下動突起を押し付けることにより、前記被塗布体の下面内側部に前記塗料を塗布する構成とした塗料塗布装置であり、個々の電子部品に塗料を安定して均一な量を供給することができ、電子部品の塗料塗布面の内側部にはみ出すことなく塗料を塗布することができるという作用を有する。
【００１４】
以下、本発明の実施の形態について、電子部品の一例として固体電解コンデンサを例に図面を用いて説明する。
【００１５】
図１は本発明の実施の形態における電子部品などの塗料塗布装置の要部構成を示す斜視図、図２は同塗料槽の平面図、図３は同断面図、図４は同塗料転写ブロックの平面図、図５は同塗料転写ブロックの正面図、図６は同塗料槽とスキージのはめあいを示す正面図、図７は同スキージの取付けを示す平面図、図８（ａ）〜（ｃ）は同塗布状態を示す断面図、そして図９は固体電解コンデンサの斜視図である。
【００１６】
電子部品であるところの固体電解コンデンサは、例えば図９に示すように固体電解コンデンサの構成素子２２の下面内側部に、構成部材である絶縁体材、導電体材、誘電体材、磁性体材あるいはそれらの混合体材である塗料２１を塗布し、所定数の構成素子２２を積層することにより構成されるのである。
【００１７】
図１において、１は前記塗料２１と同じ構成の塗料１１を貯蔵する塗料槽であり、金属材などでなる直方体の内部を繰り抜いたバケット形状をしており、その内部底面には断面が四角形で複数本、本実施の形態では２本の筋状の突起２ａ，２ｂ，２ｃが平行して設置されている。
【００１８】
なお、図２および図３に示すように、直交して設けたくし歯状の溝１６により、突起２ａ，２ｂ，２ｃはそれぞれ個々に分離されており、塗料槽１は突起２ａ，２ｂ，２ｃの長手方向に移動自在としている。
【００１９】
３は金属材でなりアングル状の上下移動自在な塗料転写ブロックであり、上端には前記上下移動自在のための軸５が挿通され、下端は突起２ａ，２ｂ，２ｃの長手方向と直交して溝１６と同じ断面形状で、溝１６にはめこみ可能となっている。
【００２０】
この塗料転写ブロック３の下端上面には、図４、図５に示すように突起２ａ，２ｂ，２ｃと同ピッチで複数の突起４が設けられており、突起２ａ，２ｂ，２ｃでなる突起の一部を形成している。突起４の水平表面積はコンデンサ素子１２の下面面積よりも小さくなっている。
【００２１】
塗料槽１の上面側には、対向した対のスキージ６ａ，６ｂが配設されており、図６に示すようにスキージ６ａ，６ｂのそれぞれの下端部には前記突起２ａ，２ｂ，２ｃが所定のすきまを保持してはまり込む溝１７ａ，１７ｂを設けてある。
【００２２】
また、図７に示すようにスキージ６ａ，６ｂの左右両端は断面がく字状に曲げ加工されており、曲げ加工の先端部分が対向するようにそれぞれプレート７の下端部に取付けられ、またそれぞれのプレート７の上端部は同じくブラケット８に取付けられており、ブラケット８の一端に挿通した軸９に沿って上下移動自在となっている。
【００２３】
１９は塗料供給部であり、２組のスキージ６ａ，６ｂの中間に配置されているシリンジ１０で構成され、塗料槽１内の塗料１１が常に所定量となるように塗料槽１に塗料１１を断続的に供給する。
【００２４】
１８は素子供給部であり、塗料転写ブロック３の突起４に対応する上方に配置されており、被塗布体の前記構成素子２２であるところの複数のコンデンサ素子１２を保持する複数の吸着ヘッド１３と、吸着ヘッド１３を一端に取付けたブロック１４と、ブロック１４の他端を挿通する軸１５で構成され、ブロック１４は軸１５に沿って上下移動自在となっている。
【００２５】
次に、塗料塗布動作について説明する。図１において、シリンジ１０から塗料１１が塗料槽１に所定量供給され、塗料槽１が矢印イ方向に移動（駆動機構は図示せず）する。その塗料槽１の移動中はスキージ６ｂが下降（駆動機構は図示せず）しており、溝１７ｂが突起２ｃにはまりこんでおり、またスキージ６ａは上昇（駆動機構は図示せず）しており、溝１７ａは突起２ｃから離れた上方にあり、スキージ６ｂの移動方向の側面により塗料１１が突起２ａ，２ｂ，２ｃおよび突起４上に移動して所定厚みに塗布される。
【００２６】
次にスキージ６ｂは上昇し、またスキージ６ａは下降して溝１７ａが突起２ａにはまりこみ、溝１７ｂは突起２ａから離れた上方の位置となる。溝１７ａの形状は塗料１１の最終の塗布形状となっており、塗料槽１が矢印ア方向に移動し、図８（ａ）に示すように塗料１１が突起２ａ，２ｂ，２ｃおよび突起４上に所定厚みの塗布形状で塗布される。
【００２７】
溝１７ｂは溝１７ａよりも大きい形状であり、溝１７ｂで突起２ａ，２ｂ，２ｃおよび突起４上への塗料１１の粗形成を、そして溝１７ａで突起２ａ，２ｂ，２ｃおよび突起４上への塗料１１の最終仕上形成を行うのであり、以上の２段階による塗料１１の塗布形成により、塗料１１における塗布量の精度向上と安定化を図っている。
【００２８】
また、スキージ６ａ，６ｂの両端はく字状に曲げ加工されているため、塗料１１をかきとる際、塗料１１が突起２ａ，２ｂ，２ｃにかき寄せられ塗料槽１から溢れ出るなどの不具合を防止している。
【００２９】
さて、塗料槽１の移動とともに、塗料転写ブロック３も下端が溝１６にはまりこんだまま移動する。塗料槽１が矢印ア方向に移動し、塗料１１が突起２ａ，２ｂ，２ｃおよび突起４上に所定の塗布形状にて塗布された後、図８（ｂ）に示すように塗料転写ブロック３が上昇し、突起４が上方向に持ち上がり、筋状に塗布されていた塗料１１が突起４による複数の独立した個体に形成される。
【００３０】
突起４の上方における複数の吸着ヘッド１３にはコンデンサ素子１２が保持されており、吸着ヘッド１３を取付けたブロック１４が軸１５に沿って下降（駆動機構は図示せず）することにより、コンデンサ素子１２が突起４上に下降し、コンデンサ素子１２の下面に塗料１１が塗布される。なお、吸着ヘッド１３におけるコンデンサ素子１２の保持は、真空吸着で行っているが、チャックによる保持としてもさしつかえない。
【００３１】
そして、突起４の水平表面積はコンデンサ素子１２の下面面積よりも小さくしているので、コンデンサ素子１２の下面内側部に塗料１１を塗布するとともに、コンデンサ素子１２の下面からの塗料１１のはみ出しを防止している。
【００３２】
コンデンサ素子１２の下面への塗料１１の塗布量は、スキージ６ａの溝１７ａの大きさ、塗料転写ブロック３における突起４の水平表面積の大きさにより調整することができ、またコンデンサ素子１２への塗料１１の塗布位置および塗布面積は塗料転写ブロック３における突起４の水平表面積の大きさにより調整でき、そして塗布形状も突起４の表面形状を三角形、四角形、多辺形、円形、楕円形などとし、さらに深さを設けるなどにより変更可能となることは言うまでもない。
【００３３】
以上、塗料１１が突起２ａ，２ｂ，２ｃおよび突起４上に所定の塗布形状に塗布された後、塗料転写ブロック３が上昇する動作の例を示し説明したが、図８（ｃ）に示すように、塗料転写ブロック３を下降させて突起４を下降することにより、突起２ａ，２ｂ上に必要な個別の塗料１１を形成し、コンデンサ素子１２を下降させてその下面の所定箇所に塗布するようにしてもよく、その構成方法によれば突起２ａ，２ｂは上下移動しないため、上下移動時の振動などによる塗料１１の形状の変化が少なく、コンデンサ素子１２の下面に対する塗料１１の塗布量の安定化が一層図れる。
【００３４】
【発明の効果】
以上のように本発明の塗料塗布装置によれば、電子部品の塗布面より小さい水平表面積を有する突起上に、塗料の層を安定して均一に形成した後に押し付けることで、電子部品の塗布面に塗料を塗布することができるので、塗布面である電子部品の下面内側部から塗料がはみ出すことがなく、塗装品質を向上させることができる。さらに、塗料がはみ出すことが無いので、電子部品の製品寸法不良を低減し、設備のメンテナンス性を向上させることができる効果も同時に奏するものである。

For example, as shown in FIG. 9, the solid electrolytic capacitor as an electronic component has an insulating material, a conductive material, a dielectric material, and a magnetic material, which are constituent members, on the inner surface of the lower surface of the component 22 of the solid electrolytic capacitor. Or it is comprised by apply | coating the coating material 21 which is those mixture materials, and laminating | stacking the predetermined number of component elements 22. FIG.
[0017]
In FIG. 1, reference numeral 1 denotes a paint tank for storing paint 11 having the same configuration as that of paint 21 and has a bucket shape in which a rectangular parallelepiped made of a metal material or the like is pulled out. In the present embodiment, two line-like protrusions 2a, 2b, 2c are installed in parallel.
[0018]
As shown in FIGS. 2 and 3, the protrusions 2a, 2b and 2c are individually separated by the comb-shaped grooves 16 provided orthogonal to each other, and the coating tank 1 has the protrusions 2a, 2b and 2c. It is movable in the longitudinal direction.
[0019]
Reference numeral 3 denotes an angle-shaped paint transfer block which is made of a metal material and can be moved up and down. The shaft 5 for the vertical movement is inserted into the upper end, and the lower end is orthogonal to the longitudinal direction of the protrusions 2a, 2b and 2c. It has the same cross-sectional shape as the groove 16 and can be fitted into the groove 16.
[0020]
As shown in FIGS. 4 and 5, a plurality of protrusions 4 are provided on the upper surface of the lower end of the paint transfer block 3 at the same pitch as the protrusions 2a, 2b, 2c. The protrusions 2a, 2b, 2c Forming part. The horizontal surface area of the protrusion 4 is smaller than the lower surface area of the capacitor element 12.
[0021]
A pair of opposed squeegees 6a and 6b are disposed on the upper surface side of the paint tank 1, and as shown in FIG. 6, the protrusions 2a, 2b and 2c are predetermined at the lower ends of the squeegees 6a and 6b. Grooves 17a and 17b are provided to hold the gap and fit.
[0022]
Further, as shown in FIG. 7, the left and right ends of the squeegees 6a and 6b are bent into a square shape in cross section, and are attached to the lower ends of the plates 7 so that the leading ends of the bending process are opposed to each other. The upper end portion of the plate 7 is similarly attached to the bracket 8 and is movable up and down along a shaft 9 inserted into one end of the bracket 8.
[0023]
A paint supply unit 19 is composed of a syringe 10 disposed between two sets of squeegees 6a and 6b, and the paint 11 is placed in the paint tank 1 so that the amount of the paint 11 in the paint tank 1 is always a predetermined amount. Supply intermittently.
[0024]
Reference numeral 18 denotes an element supply unit, which is arranged above the protrusion 4 of the paint transfer block 3 and has a plurality of suction heads 13 for holding a plurality of capacitor elements 12 which are the constituent elements 22 of the object to be coated. And a block 14 having an adsorption head 13 attached to one end thereof, and a shaft 15 inserted through the other end of the block 14. The block 14 is movable up and down along the shaft 15.
[0025]
Next, the paint application operation will be described. In FIG. 1, a predetermined amount of paint 11 is supplied from a syringe 10 to the paint tank 1, and the paint tank 1 moves in the direction of arrow A (a drive mechanism is not shown). While the paint tank 1 is moving, the squeegee 6b is lowered (drive mechanism is not shown), the groove 17b is stuck in the protrusion 2c, and the squeegee 6a is raised (drive mechanism is not shown). The groove 17a is located above the protrusion 2c, and the paint 11 moves onto the protrusions 2a, 2b, 2c and the protrusion 4 by the side surface in the moving direction of the squeegee 6b and is applied to a predetermined thickness.
[0026]
Next, the squeegee 6b is raised, the squeegee 6a is lowered, the groove 17a is fitted into the protrusion 2a, and the groove 17b is at an upper position away from the protrusion 2a. The shape of the groove 17a is the final application shape of the paint 11, and the paint tank 1 moves in the direction of the arrow A, so that the paint 11 is on the protrusions 2a, 2b, 2c and the protrusion 4 as shown in FIG. Is applied in a coating shape having a predetermined thickness.
[0027]
The groove 17b has a larger shape than the groove 17a, and the groove 17b roughly forms the coating 11 on the protrusions 2a, 2b, 2c and the protrusion 4, and the groove 17a extends onto the protrusions 2a, 2b, 2c and the protrusion 4. The final finish formation of the coating material 11 is performed, and the coating amount of the coating material 11 is improved and stabilized by applying and forming the coating material 11 in the above two steps.
[0028]
Further, since both ends of the squeegees 6a and 6b are bent into a square shape, when the paint 11 is scraped, the problem that the paint 11 is scraped to the protrusions 2a, 2b and 2c and overflows from the paint tank 1 is prevented. is doing.
[0029]
As the paint tank 1 moves, the paint transfer block 3 also moves with its lower end stuck in the groove 16. After the paint tank 1 moves in the direction of arrow A and the paint 11 is applied on the protrusions 2a, 2b, 2c and the protrusion 4 in a predetermined application shape, the paint transfer block 3 is moved as shown in FIG. The protrusion 4 rises upward, and the paint 11 applied in a streak shape is formed on the plurality of independent individuals by the protrusion 4.
[0030]
Capacitor elements 12 are held on the plurality of suction heads 13 above the protrusions 4, and the block 14 to which the suction heads 13 are attached descends along the shaft 15 (the drive mechanism is not shown). 12 descends onto the protrusion 4 and the paint 11 is applied to the lower surface of the capacitor element 12. Although the capacitor element 12 is held by the suction head 13 by vacuum suction, it may be held by a chuck.
[0031]
Since the horizontal surface area of the protrusion 4 is smaller than the lower surface area of the capacitor element 12, the paint 11 is applied to the inner surface of the lower surface of the capacitor element 12 and the protrusion of the paint 11 from the lower surface of the capacitor element 12 is prevented. is doing.
[0032]
The coating amount of the coating material 11 on the lower surface of the capacitor element 12 can be adjusted by the size of the groove 17a of the squeegee 6a and the size of the horizontal surface area of the protrusion 4 in the coating material transfer block 3. 11 can be adjusted according to the size of the horizontal surface area of the protrusions 4 in the paint transfer block 3, and the surface shape of the protrusions 4 is triangular, quadrilateral, polygonal, circular, elliptical, etc. Needless to say, the depth can be changed by providing a depth or the like.
[0033]
The example of the operation in which the paint transfer block 3 ascends after the paint 11 is applied to the protrusions 2a, 2b, 2c and the protrusion 4 in a predetermined application shape has been described above, but as shown in FIG. In addition, the paint transfer block 3 is lowered to lower the protrusion 4 to form the necessary individual paint 11 on the protrusions 2a and 2b, and the capacitor element 12 is lowered to be applied to a predetermined portion on the lower surface thereof. However, according to the configuration method, since the protrusions 2a and 2b do not move up and down, there is little change in the shape of the paint 11 due to vibration or the like during up and down movement, and the coating amount of the paint 11 on the lower surface of the capacitor element 12 is stable. Can be further improved.
[0034]
【The invention's effect】
As described above, according to the coating material application apparatus of the present invention, the coating surface of the electronic component is formed by pressing the coating layer on the projection having a horizontal surface area smaller than the coating surface of the electronic component after being stably and uniformly formed. Since the paint can be applied to the surface, the paint does not protrude from the inner surface of the lower surface of the electronic component, which is the application surface, and the coating quality can be improved. Furthermore, since the paint does not protrude, it is possible to simultaneously reduce the product dimensional defects of the electronic parts and improve the maintainability of the equipment.
