Description
本發明係相關於一種薄膜塗佈裝置及薄膜塗佈方法，尤指一種可提高塗佈材料厚度均勻性的薄膜塗佈裝置及薄膜塗佈方法。The present invention relates to a film coating apparatus and a film coating method, and more particularly to a film coating apparatus and a film coating method which can improve the thickness uniformity of a coating material.
請參考第1圖，第1圖是習知薄膜塗佈裝置的示意圖。如第1圖所示，習知薄膜塗佈裝置100包含一輸送滾輪110用以輸送一薄膜F，以及一塗佈模頭120用以直接將塗佈材料C塗佈於薄膜F上。為了使塗佈材料C於薄膜F上的形成厚度一致，塗佈模頭120和輸送滾輪110的表面會間隔一固定距離。然而，如第2圖所示，當薄膜F的厚度變異較大時，由於塗佈模頭120和輸送滾輪110的表面之間的距離是固定的，因此塗佈材料C於薄膜F上的形成厚度會不一致。尤其是當薄膜F的某部分的厚度較厚時，塗佈材料C有可能因厚度不足而容易從薄膜F上剝離，或者塗佈材料C有可能因厚度不足而無法提供正常功能。Please refer to FIG. 1 , which is a schematic view of a conventional film coating apparatus.

In order to make the thickness of the coating material C uniform on the film F, the surfaces of the coating die 120 and the conveying roller 110 are spaced apart by a fixed distance. However, as shown in Fig. 2, when the thickness variation of the film F is large, since the distance between the surface of the coating die 120 and the conveying roller 110 is fixed, the formation of the coating material C on the film F is performed. The thickness will be inconsistent. In particular, when the thickness of a certain portion of the film F is thick, the coating material C may be easily peeled off from the film F due to insufficient thickness, or the coating material C may not provide a normal function due to insufficient thickness.
本發明之目的在於提供一種可提高塗佈材料厚度均勻性的薄膜塗佈裝置及薄膜塗佈方法，以解決先前技術的問題。SUMMARY OF THE INVENTION An object of the present invention is to provide a thin film coating apparatus and a thin film coating method which can improve the uniformity of thickness of a coating material to solve the problems of the prior art.

相較於先前技術，本發明薄膜塗佈裝置可以均勻地將塗佈材料塗佈於薄膜上，以使塗佈材料於薄膜上的形成厚度一致，而不會受到薄膜厚度變異的影響，因此本發明薄膜塗佈裝置可提高塗佈材料厚度的均勻性。再者，本發明薄膜塗佈裝置的第一滾輪的位置可以隨著薄膜表面起伏進行微調，因此本發明薄膜塗佈裝置不須在薄膜與薄膜的接續處停止塗佈作業，故本發明薄膜塗佈裝置可以提供較佳的塗佈效率及操作便利性。Compared with the prior art, the film coating device of the present invention can uniformly apply the coating material to the film so that the thickness of the coating material formed on the film is uniform without being affected by the film thickness variation, so The film coating apparatus of the invention can improve the uniformity of the thickness of the coating material. Furthermore, the position of the first roller of the film coating apparatus of the present invention can be finely adjusted with the surface roughness of the film, so that the film coating apparatus of the present invention does not need to stop the coating operation at the joint of the film and the film, so the film coating of the present invention The cloth device can provide better coating efficiency and ease of operation.
請參考第3圖，第3圖是本發明薄膜塗佈裝置的示意圖。如第3圖所示，本發明薄膜塗佈裝置200包含一第一滾輪210，一塗佈模頭220以及一第二滾輪230。第一滾輪210具有一剛性表面，舉例來說，第一滾輪210可以是一金屬滾輪，但本發明不以此為限。再者，第一滾輪210的剛性表面可以是平滑表面。塗佈模頭220是設置於第一滾輪210的一側，用以施加一塗佈材料C於第一滾輪210的剛性表面。另外，塗佈模頭220和第一滾輪210的剛性表面間隔一預定距離，且塗佈模頭220於施加塗佈材料C時的流量固定。第二滾輪230具有一彈性表面，舉例來說，第二滾輪230可以是一橡膠滾輪，但本發明不以此為限。第二滾輪230的彈性表面用以輸送一薄膜F，且用以抵接於第一滾輪210的剛性表面。Please refer to Fig. 3, which is a schematic view of the film coating apparatus of the present invention. As shown in FIG. 3, the film coating apparatus 200 of the present invention comprises a first roller 210, a coating die 220 and a second roller 230. The first roller 210 has a rigid surface. For example, the first roller 210 can be a metal roller, but the invention is not limited thereto. Furthermore, the rigid surface of the first roller 210 can be a smooth surface. The coating die 220 is disposed on one side of the first roller 210 for applying a coating material C to the rigid surface of the first roller 210. In addition, the coating die 220 and the rigid surface of the first roller 210 are spaced apart by a predetermined distance, and the flow rate of the coating die 220 when the coating material C is applied is fixed. The second roller 230 has a resilient surface. For example, the second roller 230 can be a rubber roller, but the invention is not limited thereto. The elastic surface of the second roller 230 is used to transport a film F and is used to abut against the rigid surface of the first roller 210.
當第一滾輪210及第二滾輪230轉動時，塗佈模頭220會以固定流量施加塗佈材料C於第一滾輪210的剛性表面，而第二滾輪230的彈性表面會以固定速度輸送薄膜F。由於第一滾輪210的剛性表面及第二滾輪230的彈性表面於抵接位置P的切線速度的方向相反，第一滾輪210的剛性表面上的塗佈材料C會被進一步轉移至薄膜F的表面。When the first roller 210 and the second roller 230 rotate, the coating die 220 applies the coating material C to the rigid surface of the first roller 210 at a fixed flow rate, and the elastic surface of the second roller 230 transports the film at a fixed speed. F. Since the rigid surface of the first roller 210 and the elastic surface of the second roller 230 are opposite in the direction of the tangential speed of the abutting position P, the coating material C on the rigid surface of the first roller 210 is further transferred to the surface of the film F. .
依據上述配置，第一滾輪210的剛性表面上的塗佈材料C會以定量方式塗佈於薄膜F表面上的每單位面積，因此即使薄膜F的厚度變異很大，塗佈材料C於薄膜F上的形成厚度仍會一致。換句話說，當使用本發明薄膜塗佈裝置200將塗佈材料C施加於薄膜F上時，塗佈材料C於薄膜F上的形成厚度不會受到薄膜F厚度變異的影響。因此本發明薄膜塗佈裝置200可提高塗佈材料C厚度的均勻性。According to the above configuration, the coating material C on the rigid surface of the first roller 210 is applied in a quantitative manner to each unit area on the surface of the film F, so even if the thickness of the film F varies greatly, the coating material C is applied to the film F. The formation thickness on the top will still be the same. In other words, when the coating material C is applied to the film F using the film coating apparatus 200 of the present invention, the thickness of the coating material C formed on the film F is not affected by the variation of the thickness of the film F. Therefore, the film coating apparatus 200 of the present invention can improve the uniformity of the thickness of the coating material C.
本發明薄膜塗佈裝置200可另包含一刮刀260與一盛盤270設置於第一滾輪210下方。刮刀260用以於第一滾輪210抵接於 第二滾輪230之前刮除第一滾輪210的剛性表面上的異物及/或前次塗佈殘留的塗佈材料。盛盤270是用以接收刮刀260 刮除下來的異物及/或塗佈材料。The film coating apparatus 200 of the present invention may further include a scraper 260 and a tray 270 disposed under the first roller 210. The scraper 260 is used to scrape foreign matter on the rigid surface of the first roller 210 and/or to apply the remaining coating material before the first roller 210 abuts against the second roller 230. The tray 270 is for receiving foreign matter and/or coating material scraped off by the blade 260 .
再者，當塗佈材料C被轉移至薄膜F的表面後，薄膜F可以被進一步輸送至烘乾裝置250中，以對塗佈材料C進行烘乾。被烘乾的塗佈材料C會於薄膜F上形成具特定功能的層狀結構，例如用於接著的黏著層，但本發明不以此為限。Further, after the coating material C is transferred to the surface of the film F, the film F may be further conveyed to the drying device 250 to dry the coating material C. The dried coating material C forms a layered structure having a specific function on the film F, for example, for the subsequent adhesive layer, but the invention is not limited thereto.
另外，本發明薄膜塗佈裝置200可另包含一流體壓力致動器240（例如是氣壓缸）連接於第一滾輪210。流體壓力致動器240可用以推動第一滾輪210經由薄膜F抵接於第二滾輪230，並使第一滾輪210以一預定壓力抵接於第二滾輪230。由於流體壓力致動器240的推動行程可以伸縮，當薄膜F的厚度不均時，第一滾輪210的位置可以隨著薄膜F表面起伏進行微調，再者，第二滾輪230的彈性表面亦可以吸收薄膜F厚度的部分變異量，因此第一滾輪210可以維持在抵接於第二滾輪230的狀態，並容許各種不同厚度的薄膜F通過第一滾輪210和第二滾輪230之間，換句話說，第一滾輪210和第二滾輪230之間的距離等於薄膜F的厚度。另一方面，如第4圖所示，當第二滾輪230輸送薄膜F時，即使薄膜F與薄膜F之間的接續處的厚度較厚(約為薄膜F厚度的兩倍)，第一滾輪210的位置仍可隨著薄膜F表面起伏進行微調，以使第一滾輪210維持在抵接於第二滾輪230的狀態，進而讓塗佈材料C持續地轉移至薄膜F的表面。相較於習知薄膜塗佈裝置必須在薄膜F與薄膜F的接續處停止塗佈作業，以避免薄膜F與薄膜F的接續處在經過塗佈模頭時因厚度過厚而無法通過，本發明薄膜塗佈裝置200可以提供較佳的塗佈效率及操作便利性。In addition, the film coating apparatus 200 of the present invention may further include a fluid pressure actuator 240 (for example, a pneumatic cylinder) connected to the first roller 210. The fluid pressure actuator 240 can be used to push the first roller 210 to abut against the second roller 230 via the film F, and the first roller 210 abuts against the second roller 230 at a predetermined pressure. Since the pushing stroke of the fluid pressure actuator 240 can be expanded and contracted, when the thickness of the film F is uneven, the position of the first roller 210 can be finely adjusted according to the surface undulation of the film F. Further, the elastic surface of the second roller 230 can also be Absorbing the partial variation of the thickness of the film F, so that the first roller 210 can be maintained in a state of abutting against the second roller 230, and allowing the film F of various thicknesses to pass between the first roller 210 and the second roller 230, in other words. In other words, the distance between the first roller 210 and the second roller 230 is equal to the thickness of the film F. On the other hand, as shown in FIG. 4, when the second roller 230 transports the film F, even if the thickness between the film F and the film F is thick (about twice the thickness of the film F), the first roller The position of 210 may still be finely adjusted as the surface of the film F is undulated to maintain the first roller 210 in a state of abutting against the second roller 230, thereby continuously transferring the coating material C to the surface of the film F. Compared with the conventional film coating device, it is necessary to stop the coating operation at the connection between the film F and the film F, so as to prevent the film F and the film F from passing through the coating die because the thickness is too thick to pass. The inventive thin film coating apparatus 200 can provide better coating efficiency and ease of operation.
相對地，當第一滾輪210的位置隨著薄膜F的厚度進行微調時，塗佈模頭220和第一滾輪210是連動的，換句話說，塗佈模頭220和第一滾輪210的剛性表面之間的距離不會改變。In contrast, when the position of the first roller 210 is finely adjusted with the thickness of the film F, the coating die 220 and the first roller 210 are interlocked, in other words, the rigidity of the coating die 220 and the first roller 210. The distance between the surfaces does not change.
另外，在本發明實施例中，塗佈模頭220和第一滾輪210的剛性表面之間的距離可以是介於1µm和500µm之間。薄膜F的平均厚度可以是介於5µm和300µm之間。塗佈材料C的黏度可以是介於10 cps和100,000 cps之間。Additionally, in embodiments of the invention, the distance between the coating die 220 and the rigid surface of the first roller 210 may be between 1 μm and 500 μm. The average thickness of the film F may be between 5 μm and 300 μm. The viscosity of the coating material C may be between 10 cps and 100,000 cps.
另一方面，請參考第5圖，第5圖是本發明塗佈模頭的示意圖。如第5圖所示，本發明塗佈模頭220可以是一狹縫式塗佈模頭。塗佈模頭220的出料端形成有一狹縫222，如此可以經由調整泵送壓力來控制塗佈材料C從狹縫222輸出時的流量。On the other hand, please refer to Fig. 5, which is a schematic view of the coating die of the present invention. As shown in Fig. 5, the coating die 220 of the present invention may be a slit coating die. The discharge end of the coating die 220 is formed with a slit 222 so that the flow rate of the coating material C as it is output from the slit 222 can be controlled by adjusting the pumping pressure.
請參考第6圖。第6圖為本發明薄膜塗佈方法的流程圖600。本發明薄膜塗佈方法的流程如下列步驟：Please refer to Figure 6. Figure 6 is a flow chart 600 of a film coating method of the present invention. The flow of the film coating method of the present invention is as follows:
步驟610：提供具剛性表面的一第一滾輪及具彈性表面的一第二滾輪，其中該第二滾輪的彈性表面抵接於第一滾輪的剛性表面；Step 610: providing a first roller having a rigid surface and a second roller having a resilient surface, wherein the elastic surface of the second roller abuts against the rigid surface of the first roller;

步驟630：提供一塗佈模頭施加一塗佈材料於該第一滾輪的剛性表面；以及Step 630: providing a coating die to apply a coating material to the rigid surface of the first roller;

相較於先前技術，本發明薄膜塗佈裝置可以均勻地將塗佈材料塗佈於薄膜上，以使塗佈材料於薄膜上的形成厚度一致，而不會受到薄膜厚度變異的影響，因此本發明薄膜塗佈裝置可提高塗佈材料厚度的均勻性。再者，本發明薄膜塗佈裝置的第一滾輪的位置可以隨著薄膜表面起伏進行微調，因此本發明薄膜塗佈裝置不須在薄膜與薄膜的接續處停止塗佈作業，故本發明薄膜塗佈裝置可以提供較佳的塗佈效率及操作便利性。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。Compared with the prior art, the film coating device of the present invention can uniformly apply the coating material to the film so that the thickness of the coating material formed on the film is uniform without being affected by the film thickness variation, so The film coating apparatus of the invention can improve the uniformity of the thickness of the coating material. Furthermore, the position of the first roller of the film coating apparatus of the present invention can be finely adjusted with the surface roughness of the film, so that the film coating apparatus of the present invention does not need to stop the coating operation at the joint of the film and the film, so the film coating of the present invention The cloth device can provide better coating efficiency and ease of operation.
