Description

本発明は、二次電池用などの電極シート用芯材（例えば、銅箔やアルミ箔）の表面に、電極用材料（いわゆる、活物質や炭素材料など）および絶縁材料を塗布する装置に関する。   The present invention relates to an apparatus for applying an electrode material (so-called active material, carbon material, etc.) and an insulating material onto the surface of a core material for an electrode sheet (for example, copper foil or aluminum foil) for secondary batteries.

従来から、二次電池などの電極シートを製造する工程では、リールに巻き付けられた長尺の芯材（金属箔）を巻き出し搬送しながら、芯材の片面または両面に電極用材料を塗布し、乾燥させた後、再びリールに巻き取る、いわゆる塗布装置が用いられている。   Conventionally, in the process of manufacturing an electrode sheet such as a secondary battery, an electrode material is applied to one or both sides of a core material while unwinding and transporting a long core material (metal foil) wound around a reel. A so-called coating apparatus is used which is dried and then wound up on a reel again.

そして、この塗布装置では、電極用材料を塗布する際に、その両端部に絶縁材料を塗布しており、塗布ダイ内を隔離板によって区画（離間、隔離ともいう）し、離間して配置された電極用材料吐出口と絶縁材料の吐出口から各々電極用材料と絶縁材料とを同時に吐出させている。いる（例えば、特許文献１）。   In this coating apparatus, when the electrode material is applied, an insulating material is applied to both ends thereof, and the inside of the coating die is partitioned by a separator (also referred to as separation or separation), and is disposed separately. The electrode material and the insulating material are discharged simultaneously from the electrode material discharge port and the insulating material discharge port, respectively. (For example, Patent Document 1).

特開２００１−２１０３０４号公報JP 2001-210304 A

しかし、特許文献１のように、電極用材料と絶縁材料とが隔離した吐出口から吐出される構成の場合、電極用材料や絶縁材料が経時変化により粘度や比重が変わると、基材表面上で隣接せずに離間したり、重なり合ったり、或いは互いに混ざり合ったりする。   However, in the case of a configuration in which the electrode material and the insulating material are discharged from a discharge port separated as in Patent Document 1, if the viscosity or specific gravity of the electrode material or the insulating material changes with time, They are not adjacent to each other but are separated, overlapped, or mixed with each other.

また、段取り替えにより電極用材料や絶縁材料の粘度や比重が大きく異なる場合、塗布ダイと基材との位置や吐出条件の再調節が必要となったり、塗布ダイの共用ができずに別の塗布ダイに交換が必要となったりして、停機時間・調整作業が増え、生産性が低下する要因となっていた。   In addition, if the viscosity and specific gravity of electrode materials and insulating materials differ greatly due to changeover, it is necessary to readjust the position of the coating die and the substrate and the discharge conditions, or the coating die cannot be shared, It was necessary to replace the coating die, resulting in an increase in stoppage time and adjustment work, resulting in a decrease in productivity.

そのため、異なる塗布材料や絶縁材料を塗布できる共用の塗布ダイを設計・製作するのは、難易度が高く、非現実的であった。   Therefore, designing and manufacturing a common application die that can apply different application materials and insulating materials is difficult and impractical.

そこで本発明は、電極用材料と絶縁材料とを離間して塗布しつつ、互いが隣接ないし積層した状態に容易に調節できる塗布装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a coating apparatus that can easily adjust the electrode material and the insulating material to be adjacent to each other or stacked while coating the electrode material and the insulating material.

以上の課題を解決するために、本発明に係る一態様は、
基材の表面上に電極用材料および絶縁材料を塗布する塗布装置において、
前記基材を一方向に所定速度で搬送する基材搬送部と、
前記基材の表面に向けて前記電極用材料を吐出する電極用材料吐出口および前記絶縁材料を吐出する絶縁材料吐出口が離間して配置されている塗布ダイと、
前記塗布ダイの下流側に配置されて、前記基材上に塗布された前記絶縁材料に向けてエア噴流を吹き付けるエアノズルと、
前記エアノズルの位置および角度ならびに前記エア噴流の流量および流速の少なくとも一つを変更して、当該絶縁材料の塗布断面形状および電極用材料との隙間を調節する絶縁材料プロファイル変更部と、を備えている。 In order to solve the above problems, an aspect of the present invention is as follows.
In a coating apparatus for applying an electrode material and an insulating material on the surface of a substrate,
A base material transport unit for transporting the base material at a predetermined speed in one direction;
An application die in which an electrode material discharge port for discharging the electrode material toward the surface of the base material and an insulating material discharge port for discharging the insulating material are disposed apart from each other;
An air nozzle disposed on the downstream side of the coating die and spraying an air jet toward the insulating material coated on the substrate;
An insulating material profile changing unit that changes at least one of the position and angle of the air nozzle and the flow rate and flow velocity of the air jet to adjust the gap between the insulating material application cross-sectional shape and the electrode material; Yes.

この一態様によれば、電極用材料吐出口と絶縁材料吐出口と離間しているため、吐出される電極用材料と絶縁材料とが混じり合うことがない。そして、エアノズルのエア噴流で、流動性の高い絶縁材料が電極用材料側に寄り添うように移動させ、所望の積層状態を形成させることができる。   According to this aspect, since the electrode material discharge port and the insulating material discharge port are separated from each other, the discharged electrode material and the insulating material are not mixed. Then, the air jet flow of the air nozzle can be moved so that the highly fluid insulating material is close to the electrode material side to form a desired laminated state.

基材に塗布する電極用材料や絶縁材料の粘度が経時的に変化したり、段取り替えなど流動特性が変わっても、使用する一体型の塗布ダイや塗布条件を変えることなく、電極用材料と絶縁材料とを離間して塗布しつつ、互いが隣接ないし積層した状態に容易に調節できる。そのため、ノズルの設計・製作は容易となり、調整作業にかかる時間が短縮され、生産性も向上する。   Even if the viscosity of the electrode material or insulating material applied to the base material changes over time or the flow characteristics change, such as setup change, without changing the integrated application die and application conditions to be used, While being applied separately from the insulating material, it can be easily adjusted to be adjacent or stacked. Therefore, the design and production of the nozzle becomes easy, the time required for the adjustment work is shortened, and the productivity is improved.

The opposite direction is expressed as below. A direction of rotation about the Z direction is expressed as θ.

図１は、本発明を具現化する形態の一例の全体構成を示す概略図である。図１には、本発明に係る塗布装置１の概略図が示されている。   FIG. 1 is a schematic diagram showing an overall configuration of an example of a form embodying the present invention. FIG. 1 shows a schematic view of a coating apparatus 1 according to the present invention.

塗布装置１は、基材Ｓの表面上に電極用材料および絶縁材料を塗布するものである。塗布装置１は、基材搬送部２、塗布ダイ３、絶縁材料塗布端部位置検出部４、エアノズル５、絶縁材料プロファイル変更部６を備えている。   The coating apparatus 1 applies an electrode material and an insulating material on the surface of the substrate S. The coating apparatus 1 includes a substrate transport unit 2, a coating die 3, an insulating material coating end position detection unit 4, an air nozzle 5, and an insulating material profile changing unit 6.

基材搬送部２は、基材Ｓを一方向（例えば、矢印ｖで示す方向）に所定速度で搬送するものである。
具体的には、基材搬送部２は、不図示の巻出装置や巻取装置、バックアップロール２１などを備えている。 The base material transport unit 2 transports the base material S in one direction (for example, the direction indicated by the arrow v) at a predetermined speed.
Specifically, the base material conveyance unit 2 includes an unillustrated unwinding device, a winding device, a backup roll 21, and the like.

巻出装置は、ロール状に巻き付けられた基材Ｓを巻き出しながら供給するものである。巻取装置は、塗布された材料を乾燥させた後、再びロール状に巻き取るものである。   The unwinding device supplies the substrate S wound in a roll shape while unwinding. The winding device is to wind the applied material again in a roll after drying the applied material.

バックアップロール２１は、搬送中の基材Ｓに所定の張力を付与して、しわや弛みを無くすものである。また、バックアップロール２１は、塗布ダイ３との間隔を一定に保ちながら基材Ｓを搬送するためのものである。具体的には、バックアップロール２１は、表面が平滑な円筒状の部材で構成されている。   The backup roll 21 applies a predetermined tension to the substrate S being transported to eliminate wrinkles and slack. Further, the backup roll 21 is for transporting the substrate S while keeping the distance from the coating die 3 constant. Specifically, the backup roll 21 is composed of a cylindrical member having a smooth surface.

塗布ダイ３は、基材Ｓの表面に向けて電極用材料Ｌ１および絶縁材料Ｌ２を吐出するものである。   The coating die 3 discharges the electrode material L1 and the insulating material L2 toward the surface of the substrate S.

塗布ダイ３の本体３０には、電極用材料Ｌ１を吐出するための電極用材料吐出口３１が備えられており、その両端部外側には、絶縁材料Ｌ２を吐出するための絶縁材料吐出口３２がそれぞれ備えられている。なお、これら電極用材料吐出口３１と絶縁材料吐出口３２とは、離間して配置されている。   The body 30 of the coating die 3 is provided with an electrode material discharge port 31 for discharging the electrode material L1, and an insulating material discharge port 32 for discharging the insulating material L2 outside the both ends. Are provided. The electrode material discharge port 31 and the insulating material discharge port 32 are spaced apart.

基材Ｓに電極用材料Ｌ１および絶縁材料Ｌ２を塗布する際、塗布ダイ３は、破線３０’で示す位置に配置され、電極用材料吐出口３１と絶縁材料吐出口３２の先端部が、基材Ｓと所定の間隔（いわゆる、塗布ギャップ）を隔てた状態で、電極用材料Ｌ１および絶縁材料Ｌ２の吐出が行われる。   When the electrode material L1 and the insulating material L2 are applied to the base material S, the coating die 3 is disposed at a position indicated by a broken line 30 ′, and the tip portions of the electrode material discharge port 31 and the insulating material discharge port 32 are located at the base. The electrode material L1 and the insulating material L2 are discharged while being separated from the material S by a predetermined distance (so-called application gap).

そのため、基材Ｓの表面に塗布された電極用材料Ｌ１と絶縁材料Ｌ２との間には、隙間Ｇが生じる。   Therefore, a gap G is generated between the electrode material L1 applied to the surface of the substrate S and the insulating material L2.

絶縁材料塗布端部位置検出部４は、塗布ダイ３の下流側に配置されて、基材Ｓ上に塗布された絶縁材料Ｌ２の端部位置情報を検出するものである。   The insulating material application end position detection unit 4 is arranged on the downstream side of the application die 3 and detects end position information of the insulating material L2 applied on the substrate S.

具体的には、絶縁材料塗布端部位置検出部４は、基材Ｓ幅方向の絶縁材料Ｌ２の端部位置（つまり、絶対的な端部位置情報）や、電極用材料Ｌ１および絶縁材料Ｌ２の端部の隙間寸法（つまり、相対的な端部位置情報）を検出するものである。   Specifically, the insulating material application end position detection unit 4 includes the end position of the insulating material L2 in the width direction of the base material S (that is, absolute end position information), the electrode material L1, and the insulating material L2. The gap dimension (that is, relative end portion position information) of the end portion is detected.

より具体的には、絶縁材料塗布端部位置検出部４として、基材Ｓの幅方向に所定の長さを有する帯状のビームＬＢを基材Ｓの表面に対して斜め方向から照射し、反射光の位置を計測することで、基材Ｓの表面形状や段差などを測定する変位計（いわゆる、プロファイラ）を用いる。このとき、帯状のビームＬＢが、電極用材料Ｌ１ないし絶縁材料Ｌ２の端部に亘って照射されるように、絶縁材料塗布端部位置検出部４を設置する。そうすることで、基材Ｓ上に塗布された絶縁材料Ｌ２の絶対的または相対的な端部位置情報が検出できる。   More specifically, as the insulating material application end position detection unit 4, a strip-shaped beam LB having a predetermined length in the width direction of the base material S is irradiated obliquely with respect to the surface of the base material S and reflected. A displacement meter (so-called profiler) that measures the surface shape, level difference, etc. of the substrate S is used by measuring the position of light. At this time, the insulating material application end position detecting unit 4 is installed so that the belt-like beam LB is irradiated over the end portions of the electrode material L1 or the insulating material L2. By doing so, the absolute or relative end position information of the insulating material L2 applied on the substrate S can be detected.

エアノズル５は、塗布ダイ３の下流側に配置されて、基材Ｓ上に塗布された絶縁材料Ｌ２に向けてエア噴流Ｊを吹き付けるものである。ここでは、エアノズル５は、絶縁材料塗布端部位置検出部４の下流側に配置されている構成を例示する。   The air nozzle 5 is disposed on the downstream side of the coating die 3 and blows an air jet J toward the insulating material L2 coated on the substrate S. Here, the configuration in which the air nozzle 5 is disposed on the downstream side of the insulating material application end position detection unit 4 is illustrated.

具体的には、エアノズル５は、絶縁材料Ｌ２が塗布された外側（つまり、電極用材料Ｌ１が塗布された側と逆側）よりもさらに外側に、ノズルの先端部を配置しておく。また、エアノズル５の先端部は、エア噴流Ｊの吹き出す方向と基材Ｓの表面とが概ね垂直となる様に配置されている。或いは、エアノズル５の先端部を電極用材料Ｌ１が塗布された側（つまり、内側）に傾斜させ、エア噴流Ｊが内側により強く吹き出す様な配置としても良い。この様な配置とすることで、絶縁材料Ｌ２が塗布された外側の端部に対し、さらにその外側から内側に向けてエア噴流Ａが吹き付けられるため、塗布された絶縁材料Ｌ２の表面が押し潰されながら電極用材料Ｌ１との隙間Ｇ，Ｇ’が狭くなる様に拡がり、電極用材料Ｌ１と絶縁材料Ｌ２とが接したり、更には電極用材料Ｌ１に絶縁材料Ｌ２が重なり合った状態にすることができる。   Specifically, in the air nozzle 5, the tip of the nozzle is disposed further outside than the outside where the insulating material L2 is applied (that is, the side opposite to the side where the electrode material L1 is applied). Further, the tip of the air nozzle 5 is arranged so that the direction in which the air jet J blows out and the surface of the substrate S are substantially perpendicular. Alternatively, the tip of the air nozzle 5 may be inclined to the side where the electrode material L1 is applied (that is, the inner side) so that the air jet J blows out more strongly on the inner side. With such an arrangement, the air jet A is blown from the outer side toward the inner side of the outer end portion to which the insulating material L2 is applied, so that the surface of the applied insulating material L2 is crushed. However, the gaps G and G ′ with the electrode material L1 are widened so that the electrode material L1 and the insulating material L2 are in contact with each other, and the insulating material L2 is overlapped with the electrode material L1. Can do.

絶縁材料プロファイル変更部６は、塗液端部位置検出部４で検出された、絶縁材料Ｌ２の端部位置情報に基づいて、エアノズル５の位置および角度ならびにエア噴流Ｊの流量および流速の少なくとも一つを変更して、絶縁材料Ｌ１の塗布断面形状および端部位置（いわゆる、プロファイル）を調節するものである。   The insulating material profile changing unit 6 is based on the end position information of the insulating material L2 detected by the coating liquid end position detecting unit 4 and at least one of the position and angle of the air nozzle 5 and the flow rate and flow velocity of the air jet J. The cross-sectional shape and end position (so-called profile) of the insulating material L1 are adjusted by changing one of them.

例えば、エアノズル５の先端部（つまり、エア噴流の噴出口）を基材Ｓの幅方向（つまり、Ｙ方向）や基材Ｓの厚み方向（つまり、Ｚ方向）に移動させて（つまり、位置を変更して）、絶縁材料Ｌ２の塗布断面形状および電極用材料Ｌ１と絶縁材料Ｌ２の隙間Ｇを調節する。   For example, the tip of the air nozzle 5 (that is, the air jet outlet) is moved in the width direction (that is, the Y direction) of the substrate S or the thickness direction of the substrate S (that is, the Z direction) (that is, the position). And the gap G between the electrode material L1 and the insulating material L2 is adjusted.

具体的には、絶縁材料プロファイル変更部６は、塗液端部位置検出部４で検出された電極用材料Ｌ１と絶縁材料Ｌ２の塗布端部位置や隙間Ｇが、予め設定された基準位置や隙間寸法に対して互いが遠くにある状態にあるか近くにある状態にあるかを判定する。そして、互いが遠くにある状態にあると判定されれば、絶縁材料Ｌ２を電極用材料Ｌ１側に大きく押し広げる。一方、互いが近くにある状態にあると判定されれば、絶縁材料Ｌ２を電極用材料Ｌ１側に小さく押し広げる。   Specifically, the insulating material profile changing unit 6 is configured such that the application end positions and the gaps G of the electrode material L1 and the insulating material L2 detected by the coating liquid end position detecting unit 4 are set to the reference position or the preset position. It is determined whether the gap dimension is in a state where they are far from each other or in a state where they are close to each other. And if it determines with it being in the state which is mutually distant, the insulating material L2 will be greatly expanded to the electrode material L1 side. On the other hand, if it is determined that they are close to each other, the insulating material L2 is pushed small toward the electrode material L1 side.

より具体的には、絶縁材料プロファイル変更部６として、エアノズル５がＹ方向やＺ方向に移動可能なアクチュエータのスライダーに取り付けられた構成を例示する。そして、絶縁材料プロファイル変更部６は、電極用材料Ｌ１と絶縁材料Ｌ２が互いが遠くにある状態にあると判定されれば、エア噴流Ｊを吹き出すエアノズル５の先端部を絶縁材料Ｌ２により近づける。一方、互いが近くにある状態にあると判定されれば、エア噴流Ｊを吹き出すエアノズル５の先端部を絶縁材料Ｌ２からやや遠ざける。このように、エアノズル５が取り付けられたスライダーの位置制御を行うことで、絶縁材料Ｌ２を押し広げる度合い（つまり、絶縁材料Ｌ２の塗布断面形状および端部位置）を調節することができる。   More specifically, as the insulating material profile changing unit 6, a configuration in which the air nozzle 5 is attached to a slider of an actuator that can move in the Y direction or the Z direction is illustrated. Then, when it is determined that the electrode material L1 and the insulating material L2 are in a distant state, the insulating material profile changing unit 6 brings the tip of the air nozzle 5 that blows out the air jet J closer to the insulating material L2. On the other hand, if it is determined that they are close to each other, the tip of the air nozzle 5 that blows out the air jet J is moved slightly away from the insulating material L2. Thus, by controlling the position of the slider to which the air nozzle 5 is attached, it is possible to adjust the degree to which the insulating material L2 is spread (that is, the application cross-sectional shape and end position of the insulating material L2).

図２は、本発明を具現化する形態の一例の要部を示す概略図である。
図２（ａ）は、図１に示した塗布装置１の要部ならびに基材Ｓの表面上に塗布された電極用材料Ｌ１および絶縁材料Ｌ２を平面視したものであり、各部の位置関係が明確になるように示されている。
図２（ｂ）には、図２（ａ）にて矢視するＡ−Ａ断面図が示されており、基材Ｓの表面上に塗布された電極用材料Ｌ１、絶縁材料Ｌ２等の位置関係が明確になるように示されている。
図２（ｃ）には、図２（ａ）にて矢視するＢ−Ｂ断面図が示されており、基材Ｓの表面上に塗布された電極用材料Ｌ１、絶縁材料Ｌ２に対するエアノズル５１等の位置関係が明確になるように示されている。
図２（ｄ）には、図２（ａ）にて矢視するＣ−Ｃ断面図が示されており、基材Ｓの表面上に塗布された電極用材料Ｌ１、絶縁材料Ｌ２に対するエアノズル５２等の位置関係が明確になるように示されている。 FIG. 2 is a schematic diagram showing a main part of an example of a form embodying the present invention.
FIG. 2A is a plan view of the main part of the coating apparatus 1 shown in FIG. 1 and the electrode material L1 and the insulating material L2 applied on the surface of the substrate S. The positional relationship between the parts is as follows. Shown to be clear.
2B is a cross-sectional view taken along the line AA in FIG. 2A. The positions of the electrode material L1, the insulating material L2, and the like applied on the surface of the base material S are shown in FIG. The relationship is shown to be clear.
FIG. 2C shows a cross-sectional view taken along the line BB in FIG. 2A, and an air nozzle 51 for the electrode material L1 and the insulating material L2 applied on the surface of the substrate S. Etc. are shown so as to clarify the positional relationship.
FIG. 2D shows a cross-sectional view taken along the line CC in FIG. 2A, and an air nozzle 52 for the electrode material L1 and the insulating material L2 applied on the surface of the substrate S. Etc. are shown so as to clarify the positional relationship.

つまり、塗布ダイ３から吐出された電極用材料Ｌ１および絶縁材料Ｌ２は、それぞれ所定の隙間Ｇが生じた状態で基材Ｓの表面に塗布されるが、搬送方向下流側に配置された絶縁材料塗布端部位置検出部４にて、絶縁材料Ｌ２の絶対的または相対的な端部位置情報が検出される。そして、この絶縁材料Ｌ２の端部位置情報に基づいて、絶縁材料プロファイル変更部６で例えばエアノズル５の位置を調節して、当初は図２（ｂ）に示す様に所定の隙間Ｇを隔てて電極用材料Ｌ１と離間状態にあった絶縁材料Ｌ２を、図２（ｃ）に示す様に電極用材料Ｌ１側に押し広げ（離間の間隔が隙間Ｇ’に減少）、最終的には絶縁材料Ｌ２の塗布断面形状および端部位置を図２（ｄ）にて示す様な隣接状態に調節する。また、さらに絶縁材料Ｌ２を電極用材料Ｌ１上に押し広げ、積層状態にすることもできる。   That is, the electrode material L1 and the insulating material L2 discharged from the coating die 3 are applied to the surface of the base material S in a state where a predetermined gap G is generated, but the insulating material disposed on the downstream side in the transport direction. The application end position detection unit 4 detects absolute or relative end position information of the insulating material L2. Then, for example, the position of the air nozzle 5 is adjusted by the insulating material profile changing unit 6 based on the end position information of the insulating material L2, and initially a predetermined gap G is separated as shown in FIG. The insulating material L2 that has been separated from the electrode material L1 is spread toward the electrode material L1 side as shown in FIG. 2C (the spacing interval is reduced to the gap G ′), and finally the insulating material. The application cross-sectional shape and end position of L2 are adjusted to the adjacent state as shown in FIG. Further, the insulating material L2 can be further spread on the electrode material L1 to form a laminated state.

本発明に係る塗布装置１は、この様な構成をしているため、塗布ダイ３の電極用材料吐出口と絶縁材料吐出口とが離間していても、エアノズル５のエア噴流Ｊで、絶縁材料Ｌ２を電極用材料Ｌ１側に寄り添うように押し広げ、絶縁材料Ｌ２の断面形状および電極用材料との隙間を変更したりすることができる。   Since the coating apparatus 1 according to the present invention has such a configuration, even if the electrode material discharge port and the insulating material discharge port of the coating die 3 are separated from each other, the air jet 5 of the air nozzle 5 can be used for insulation. The material L2 can be expanded so as to approach the electrode material L1 side, and the cross-sectional shape of the insulating material L2 and the gap with the electrode material can be changed.

そのため、一体型の塗布ダイ３を用いて、流動性が経時的に変化する塗布材料を吐出する場合でも、互いの塗布材料を所望の隣接ないし積層状態に容易に調節することができる。   Therefore, even when the coating material whose fluidity changes with time is discharged using the integrated coating die 3, the coating materials can be easily adjusted to a desired adjacent or laminated state.

［絶縁材料プロファイル変更部の変形例］
なお上述では、本発明にかかる絶縁材料プロファイル変更部６として、エアノズル５の先端部をＹ方向やＺ方向に位置変更することで、絶縁材料Ｌ２の塗布断面形状および端部位置を調節する構成を例示した。 [Modification of insulation material profile change part]
In the above description, the insulating material profile changing unit 6 according to the present invention is configured to adjust the application cross-sectional shape and the end position of the insulating material L2 by changing the position of the tip of the air nozzle 5 in the Y direction or the Z direction. Illustrated.

しかし、本発明を具現化する上で、この様な構成の絶縁材料プロファイル変更部６に限らず、下述の様な構成の絶縁材料プロファイル変更部６Ｂ等であっても良い。   However, in embodying the present invention, the insulating material profile changing unit 6 configured as described below is not limited to the insulating material profile changing unit 6 having such a configuration.

図３は、本発明を具現化する形態の変形例の要部を示す概略図である。   FIG. 3 is a schematic diagram showing a main part of a modification of the embodiment embodying the present invention.

図３には、図２（ｄ）等に示した塗布装置１の絶縁材料プロファイル変更部６の変形例である、絶縁材料プロファイル変更部６Ｂが示されている。   FIG. 3 shows an insulating material profile changing unit 6B, which is a modification of the insulating material profile changing unit 6 of the coating apparatus 1 shown in FIG.

絶縁材料プロファイル変更部６Ｂは、エアノズル５の先端部の傾斜角度を変更することで、絶縁材料Ｌ２の塗布断面形状および端部位置を調節するものである。   The insulating material profile changing unit 6B adjusts the application cross-sectional shape and end position of the insulating material L2 by changing the inclination angle of the tip of the air nozzle 5.

具体的には、絶縁材料プロファイル変更部６Ｂは、絶縁材料Ｌ２の塗布端部位置を電極用材料Ｌ１側（つまり、内側）に寄せたい場合、ノズル先端部を矢印θで示す方向に傾斜させることで、エア噴流ＪのＸ方向の流量や流速を強くする。   Specifically, the insulating material profile changing unit 6B tilts the nozzle tip in the direction indicated by the arrow θ when the application end position of the insulating material L2 is to be moved toward the electrode material L1 (that is, inside). Thus, the flow rate and flow velocity in the X direction of the air jet J are increased.

より具体的には、回転ステージ機構６１やスイベル機構などの可動部材にエアノズル５を取り付け、当該可動部材の角度制御を行うことで、ノズル先端部の角度を変更してエア噴流ＪのＸ方向の流量や流速を調節し、絶縁材料Ｌ２の塗布断面形状および端部位置を調節することができる。   More specifically, the air nozzle 5 is attached to a movable member such as the rotary stage mechanism 61 or the swivel mechanism, and the angle of the movable member is controlled to change the angle of the nozzle tip to change the X direction of the air jet J. It is possible to adjust the flow rate and the flow velocity to adjust the application cross-sectional shape and end position of the insulating material L2.

さらに、本発明を具現化する上で、絶縁材料プロファイル変更部は、下述の様な構成であっても良い。   Furthermore, in order to embody the present invention, the insulating material profile changing unit may be configured as described below.

例えば、絶縁材料プロファイル変更部は、エアノズル５の先端部から噴出するエア噴流Ｊの流量および／または流速を制御する構成とする。   For example, the insulating material profile changing unit is configured to control the flow rate and / or flow velocity of the air jet J ejected from the tip of the air nozzle 5.

具体的には、絶縁材料プロファイル変更部は、絶縁材料Ｌ２の塗布端部位置を電極用材料Ｌ１側（つまり、内側）に寄せたい場合、所定の流量および／または流速でエア噴流Ｊを絶縁材料Ｌ２に向けて吹き付けたり、吹き付けるエア噴流Ｊの流量および／または流速を増やしたりする。   Specifically, when the insulating material profile changing unit wants to move the position of the coating end of the insulating material L2 toward the electrode material L1 (that is, inside), the insulating material profile changing unit sends the air jet J to the insulating material at a predetermined flow rate and / or flow velocity. Blowing toward L2, or increasing the flow rate and / or flow velocity of the air jet J to be blown.

より具体的には、エア噴流Ｊの流量および／または流速の調節は、ノズルに供給するエアのＯＮ／ＯＦＦ制御をしたり、ノズルに供給するエアの圧力を電空レギュレータなどで制御したり、絞り弁の開度を制御したりする構成とする。   More specifically, the flow rate and / or flow velocity of the air jet J is adjusted by controlling the ON / OFF of the air supplied to the nozzle, controlling the pressure of the air supplied to the nozzle with an electropneumatic regulator, The opening degree of the throttle valve is controlled.

なお、上述の絶縁材料プロファイル変更部（６，６Ｂ等）は、エアノズル５の位置や角度、エア噴流Ｊの流量および／または流速をそれぞれ独立して制御する構成を例示したが、複合的に組み合わされた構成としても良い。さらに、エアノズル５の先端部のＹ方向やＺ方向の位置、エア噴流Ｊの強弱に応じて、基材Ｓの搬送方向（つまり、Ｘ方向）にエアノズル５の位置を調節する構成としても良い。   In addition, although the above-mentioned insulating material profile change part (6, 6B etc.) illustrated the structure which controls each independently the position and angle of the air nozzle 5, and the flow volume and / or flow velocity of the air jet J, it combines in combination. It is good also as the structure made. Furthermore, it is good also as a structure which adjusts the position of the air nozzle 5 to the conveyance direction (namely, X direction) of the base material S according to the position of the front-end | tip part of the air nozzle 5, the Z direction, and the strength of the air jet J.

本発明に係る塗布装置１は、この様な構成をしているため、絶縁材料の端部位置を検出し、所望の位置に合致するように、エアノズルの位置および／またはエア噴流を調節する。エアノズルの位置および／またはエア噴流の流量若しくは流速を調節することができ、絶縁材料の厚みや端部位置を調節することができる。   Since the coating apparatus 1 according to the present invention has such a configuration, the end position of the insulating material is detected, and the position of the air nozzle and / or the air jet is adjusted so as to match the desired position. The position of the air nozzle and / or the flow rate or flow velocity of the air jet can be adjusted, and the thickness and end position of the insulating material can be adjusted.

上述では、絶縁材料塗布端部位置検出部４の下流側にエアノズル５が配置されている構成を例示した。しかし、この様な構成に限らず、絶縁材料塗布端部位置検出部４は以下の様な構成であっても良い。 [Another form]
In the above description, the configuration in which the air nozzle 5 is disposed on the downstream side of the insulating material application end position detection unit 4 is illustrated. However, the configuration is not limited to this, and the insulating material application end position detection unit 4 may have the following configuration.

１）塗布ダイ３の下流側であって、エアノズル５の上流側および下流側に配置
例えば、上述の構成に加え、図２（ａ）において破線４’で示す位置（つまり、エアノズル５の下流側）にも、上述と同様の変位計（つまり、プロファイラ）を備えた構成とする。 1) Located downstream of the coating die 3 and upstream and downstream of the air nozzle 5. For example, in addition to the above-described configuration, a position indicated by a broken line 4 'in FIG. 2A (that is, downstream of the air nozzle 5) ) Also includes a displacement meter (that is, a profiler) similar to that described above.

２）塗布ダイ３の下流側であって、エアノズル５の下流側にのみ配置
或いは、当該変位計を、塗布ダイ３の下流側であってエアノズル５の上流側には配置せず、エアノズル５の下流側にのみ配置する構成であっても良い。 2) Arranged only on the downstream side of the coating die 3 and downstream of the air nozzle 5, or the displacement meter is not disposed on the downstream side of the coating die 3 and upstream of the air nozzle 5, The structure arrange | positioned only in the downstream may be sufficient.

この様に、エアノズル５の下流側に当該変位計を配置することで、予め想定していたようななだらかな隣接状態ないし積層状態にならず、凹凸が生じた場合であっても、検出結果からエアノズル５のエア噴流Ｊの噴き出し位置や強さなどをフィードバック制御して、その後の電極用材料Ｌ１と絶縁材料Ｌ２と隣接状態ないし積層状態がなだらかな状態になる様に調節し続け、凹凸を最小限に抑えることができる。   In this way, by disposing the displacement meter on the downstream side of the air nozzle 5, a smooth adjacent state or laminated state as previously assumed is not obtained, and even if unevenness occurs, the detection result Feedback control of the ejection position and strength of the air jet J of the air nozzle 5 and the subsequent adjustment of the electrode material L1 and the insulating material L2 so that the adjacent state or the laminated state becomes a gentle state, the unevenness is minimized. To the limit.

なお上述では、本発明にかかるエアノズル５は、基材Ｓの搬送方向に複数備えられ、下流側に配置されたエアノズル５２が、上流側に配置されたエアノズル５１よりも電極用材料Ｌ１側（つまり、内側）に配置されている構成を例示した。 [Another form]
In the above description, a plurality of air nozzles 5 according to the present invention are provided in the transport direction of the substrate S, and the air nozzle 52 arranged on the downstream side is closer to the electrode material L1 side (that is, the air nozzle 51 arranged on the upstream side (that is, The configuration arranged on the inner side) is exemplified.

この様な構成であれば、流動性の高い絶縁材料の塗布端部が外側に広がることを防ぐことができる。つまり、絶縁材料の膜厚が薄くなることを防ぎ、絶縁性能を損なわずに塗布ができるので、好ましい。   With such a configuration, it is possible to prevent the coated end portion of the highly fluid insulating material from spreading outward. That is, it is preferable because the insulating material can be prevented from being thinned and can be applied without impairing the insulating performance.

しかし、本発明を具現化する上でエアノズルは、この様な構成に限らず、下述の様な構成であっても良い。   However, when embodying the present invention, the air nozzle is not limited to such a configuration, and may have the following configuration.

例えば、エアノズルは１本であっても良い。或いは、直線状に並んだ複数の細孔からエア噴流が吹き出す構造のノズル（いわゆる、フラットノズル）を備えた構成であっても良い。或いは、長楕円や帯状のエア噴流が噴き出す構造のノズル（いわゆる、平吹きノズル）を備えた構成であっても良い。   For example, the number of air nozzles may be one. Or the structure provided with the nozzle (what is called a flat nozzle) of the structure where an air jet blows off from several fine pores located in a line with a straight line may be sufficient. Or the structure provided with the nozzle (what is called a flat blowing nozzle) of the structure where an ellipse or a strip-like air jet spouts may be sufficient.

図４は、本発明を具現化する形態の別の一例の要部を示す概略図である。図４には、本発明に係るエアノズル５として、図２に例示した２つの円形断面のエアノズル５１，５２に代えて、矩形断面のエアノズル５３を１つ備えた構成が図示されている。
図４（ａ）は、矩形断面のエアノズル５３ならびに基材Ｓの表面上に塗布された電極用材料Ｌ１および絶縁材料Ｌ２を平面視したものであり、各部の位置関係が明確になるように示されている。
図４（ｂ）には、図２（ａ）にて矢視するＡ−Ａ断面図が示されており、基材Ｓの表面上に塗布された電極用材料Ｌ１、絶縁材料Ｌ２等の位置関係が明確になるように示されている。
図４（ｃ）には、図２（ａ）にて矢視するＢ−Ｂ断面図が示されており、基材Ｓの表面上に塗布された電極用材料Ｌ１、絶縁材料Ｌ２に対するエアノズル５３等の位置関係が明確になるように示されている。
図４（ｄ）には、図２（ａ）にて矢視するＣ−Ｃ断面図が示されており、基材Ｓの表面上に塗布された電極用材料Ｌ１、絶縁材料Ｌ２に対するエアノズル５３等の位置関係が明確になるように示されている。 FIG. 4 is a schematic view showing a main part of another example of a form embodying the present invention. FIG. 4 shows a configuration in which one air nozzle 53 having a rectangular cross section is provided as an air nozzle 5 according to the present invention, instead of the two air nozzles 51 and 52 having a circular cross section illustrated in FIG.
FIG. 4A is a plan view of the air nozzle 53 having a rectangular cross section and the electrode material L1 and the insulating material L2 applied on the surface of the substrate S, and is shown so that the positional relationship of each part becomes clear. Has been.
4B is a cross-sectional view taken along the line AA in FIG. 2A. The positions of the electrode material L1, the insulating material L2, and the like applied on the surface of the base material S are shown in FIG. The relationship is shown to be clear.
FIG. 4C shows a cross-sectional view taken along line B-B in FIG. 2A, and an air nozzle 53 for the electrode material L1 and the insulating material L2 applied on the surface of the substrate S. Etc. are shown so as to clarify the positional relationship.
4D is a cross-sectional view taken along the line CC in FIG. 2A, and the air nozzle 53 for the electrode material L1 and the insulating material L2 applied on the surface of the substrate S is shown. Etc. are shown so as to clarify the positional relationship.

つまり、塗布ダイ３から吐出された電極用材料Ｌ１および絶縁材料Ｌ２は、それぞれ所定の隙間Ｇが生じた状態で基材Ｓの表面に塗布されるが、搬送方向下流側に配置された絶縁材料塗布端部位置検出部４にて、絶縁材料Ｌ２の絶対的または相対的な端部位置情報が検出される。そして、この絶縁材料Ｌ２の端部位置情報に基づいて、絶縁材料プロファイル変更部６でエアノズル５３の位置を調節して、当初は図４（ｂ）に示す様に所定の隙間Ｇを隔てて電極用材料Ｌ１と離間状態にあった絶縁材料Ｌ２を、図４（ｃ）に示す様に電極用材料Ｌ１側に押し広げ（離間の間隔が隙間Ｇ’に減少）、最終的には絶縁材料Ｌ２の塗布断面形状および端部位置を図４（ｄ）にて示す様な隣接状態に調節する。また、さらに絶縁材料Ｌ２を電極用材料Ｌ１上に押し広げ、積層状態にすることもできる。   That is, the electrode material L1 and the insulating material L2 discharged from the coating die 3 are applied to the surface of the base material S in a state where a predetermined gap G is generated, but the insulating material disposed on the downstream side in the transport direction. The application end position detection unit 4 detects absolute or relative end position information of the insulating material L2. The position of the air nozzle 53 is adjusted by the insulating material profile changing unit 6 based on the end position information of the insulating material L2, and the electrodes are initially separated by a predetermined gap G as shown in FIG. As shown in FIG. 4C, the insulating material L2 that has been separated from the working material L1 is spread toward the electrode material L1 (the spacing is reduced to the gap G ′), and finally the insulating material L2 The application cross-sectional shape and end position of the coating are adjusted to the adjacent state as shown in FIG. Further, the insulating material L2 can be further spread on the electrode material L1 to form a laminated state.

なお、基材Ｓの表面とエアノズル５３先端との距離（いわゆる、ノズル高さ）や、幅方向の位置は、任意の位置に設定でき、絶縁材料プロファイル変更部６で移動させる。
また、エアノズル５３の断面形状や寸法（幅方向や搬送方向の長さ）は、絶縁材料Ｌ２の粘度や塗布幅、基材Ｓの搬送速度に応じて、適宜設定すれば良い。
また、エアノズル５３から吹き出すエア噴流Ｊの流量（風量とも言う）は、手動調節のレギュレータで適宜設定したり、電空レギュレータなどで可変式としたりしても良い。 The distance between the surface of the substrate S and the tip of the air nozzle 53 (so-called nozzle height) and the position in the width direction can be set to arbitrary positions and are moved by the insulating material profile changing unit 6.
Further, the cross-sectional shape and dimensions (width direction and transport direction length) of the air nozzle 53 may be appropriately set according to the viscosity of the insulating material L2, the coating width, and the transport speed of the substrate S.
Further, the flow rate (also referred to as air volume) of the air jet J blown from the air nozzle 53 may be appropriately set by a manually adjusted regulator, or variable by an electropneumatic regulator or the like.

［別の形態］
また、本発明にかかるエアノズル５は、温調されていない（つまり、常温の）エア噴流や冷却されたエア噴流のほか、加熱されたエア噴流を吹き付ける形態でも良い。なお、エア噴流の加熱温度は、絶縁材料の材料特性に応じて適宜決定し、設定することが好ましい。特に、加熱されたエア噴流を用いることが、常温または冷却されたエア噴流と比較して、流動性の高い絶縁材料の塗布端部が急速に固化させることができるので好ましい。そうすれば、加熱されたエア噴流で塗布された絶縁材料の外側端部から表面を乾燥させ暫定的に固化させることができるので、絶縁材料の幅方向端部が塗布直後の端部位置よりも外側に広がった状態で固化される（つまり、絶縁材料の膜厚が薄くなってしまう）ことを防ぐことができる。つまり、絶縁材料の絶縁性能を損なわなずに塗布ができると言える。 [Another form]
In addition, the air nozzle 5 according to the present invention may be configured to spray a heated air jet in addition to a temperature-controlled (that is, room temperature) air jet or a cooled air jet. The heating temperature of the air jet is preferably determined and set as appropriate according to the material characteristics of the insulating material. In particular, it is preferable to use a heated air jet because an application end portion of an insulating material having high fluidity can be rapidly solidified as compared with a normal temperature or cooled air jet. Then, since the surface can be dried and temporarily solidified from the outer end portion of the insulating material applied by the heated air jet, the width direction end portion of the insulating material is more than the end position immediately after application. It is possible to prevent solidification in a state of spreading outward (that is, the thickness of the insulating material is reduced). That is, it can be said that application can be performed without impairing the insulating performance of the insulating material.

なお上述では、本発明にかかる塗液端部位置検出部４、エアノズル５、絶縁材料プロファイル変更部６が、基材Ｓの両側端部に一組ずつ備えられた構成を例示した。 [Another form]
In the above description, the configuration in which the coating liquid end position detection unit 4, the air nozzle 5, and the insulating material profile changing unit 6 according to the present invention are provided in pairs at both end portions of the base material S is illustrated.

しかし、電極用材料Ｌ１が複数本塗布される多条塗布の場合であって、それぞれの両端部に絶縁材料Ｌ２が塗布される場合、塗液端部位置検出部４、エアノズル５、絶縁材料プロファイル変更部６を適宜追加して配置する構成でも本発明を具現化できる。   However, in the case of multi-line application in which a plurality of electrode materials L1 are applied and the insulating material L2 is applied to both ends, the coating liquid end position detection unit 4, the air nozzle 5, the insulating material profile The present invention can also be embodied by a configuration in which the changing unit 6 is appropriately added and arranged.

或いは、電極用材料Ｌ１と絶縁材料Ｌ２が１列ずつ離間して塗布される構成であれば、塗液端部位置検出部４、エアノズル５、絶縁材料プロファイル変更部６は一組のみ備えた構成でも本発明を具現化できる。   Alternatively, if the electrode material L1 and the insulating material L2 are applied separately from each other in a row, the coating liquid end position detecting unit 4, the air nozzle 5, and the insulating material profile changing unit 6 are provided with only one set. However, the present invention can be embodied.

［別の形態］
なお上述では、塗液端部位置検出部４を備えた構成をいくつか例示した。これらのような構成であれば、離間して塗布された電極用材料と絶縁材料の端部位置情報（隙間量など）を検出し、絶縁材料を移動させる幅を適宜調節することができる。 [Another form]
In the above description, several configurations including the coating liquid end position detection unit 4 are illustrated. With such a configuration, it is possible to detect edge position information (such as a gap amount) between the electrode material and the insulating material applied separately, and adjust the width for moving the insulating material as appropriate.

そのため、電極用材料と絶縁材料の吐出口が離間している一体型塗布ダイを用いて、流動性が経時的に変化する塗布材料を吐出する場合や、塗布材量と絶縁材料の隙間が経時的、周期的ないし突発的に変化する場合であっても、互いの隙間の大小に応じてエアノズルから吹き出すエア噴流の強弱を逐次調節することができるので、連続運転に好適と言える。   For this reason, when using an integrated coating die in which the discharge port for the electrode material and the insulating material are separated from each other, when a coating material whose fluidity changes with time is discharged, or when the gap between the coating material amount and the insulating material is Even in the case where the air jet changes periodically, suddenly or suddenly, the strength of the air jet blown out from the air nozzle can be sequentially adjusted according to the size of the gap between them, which is preferable for continuous operation.

しかし、材料特性に起因する隙間の大小はあるものの、塗布材量と絶縁材料の隙間が周期的ないし突発的に変化せず、経時変化もほとんど無い場合であれば、塗液端部位置検出部４を省いた構成であっても良い。この場合、最初に絶縁材料プロファイル変更部６で塗布材量と絶縁材料の隙間が無くなる様に調整しておけば、その後も継続して塗布材量と絶縁材料の隙間の無い状態を維持することができ、本発明を具現化することができる。
However, if the gap between the coating material amount and the insulating material does not change periodically or suddenly and there is almost no change over time, although there are gaps due to material characteristics, the coating liquid end position detection unit 4 may be omitted. In this case, if the insulating material profile changing unit 6 is first adjusted so that there is no gap between the coating material amount and the insulating material, the gap between the coating material amount and the insulating material is continuously maintained. The present invention can be embodied.
