Description
本發明係關於一種用於捲繞且拉出例如異方性導電接著薄膜等之一連串長尺寸接著薄膜之捲盤構件之技術。 The present invention relates to a technique for winding and pulling out a reel member of a series of long-size follow-up films such as an anisotropic conductive film.
一般而言，例如，於將液晶面板或IC晶片般之電子零件彼此進行電連接之情形，使用在絕緣性接著劑中分散有導電性粒子之異方性導電接著薄膜。 In general, for example, in the case where an electronic component such as a liquid crystal panel or an IC wafer is electrically connected to each other, an anisotropic conductive adhesive film in which conductive particles are dispersed in an insulating adhesive is used.
此外，近年來，作為用於將太陽電池用之電極電連接且進行接著之接著薄膜，使用在絕緣性接著劑中含有導電性粒子之導電性接著薄膜。如此之接著薄膜，係形成於寬度狹窄且長尺寸之剝離薄片上，且以捲繞於捲盤構件成卷狀之形態運出。 In addition, in recent years, a conductive adhesive film containing conductive particles in an insulating adhesive is used as a film for electrically connecting the electrodes for a solar cell to the subsequent adhesive film. The film thus formed is formed on a peeling sheet having a narrow width and a long size, and is taken up in a form wound around a reel member.
近年來，被期望如此之接著薄膜之長尺寸化，但一旦將接著薄膜長尺寸化，則存在有薄膜卷之直徑增加，且因其本身之重量而導致捲盤構件之凸緣部外周部產生撓曲，且阻礙接著薄膜之滑順的拉出之問題。而且，一旦無法實現接著薄膜之長尺寸化，則必需頻繁地更換捲繞有短尺寸之接著薄膜之捲盤構件，且於每次都需要停止生產線，因此導致生產效率降低。 In recent years, it has been desired to increase the size of the film, but once the film is grown, the diameter of the film roll increases, and the outer peripheral portion of the flange portion of the reel member is generated by its own weight. Flexing and hindering the problem of smooth pull-out of the film. Further, once the lengthening of the film is not possible, it is necessary to frequently replace the reel member around which the short film of the succeeding film is wound, and it is necessary to stop the production line every time, resulting in a decrease in production efficiency.

圖4係表示本發明之捲盤構件1之各部分之尺寸關係的說明圖。本發明之捲盤構件1，以對長尺寸(300~600 m)之接著薄膜6具有功效之方式，具有直徑較大之第1及第2凸緣部11、12。 Fig. 4 is an explanatory view showing the dimensional relationship of each portion of the reel member 1 of the present invention. The reel member 1 of the present invention has first and second flange portions 11 and 12 having a large diameter so as to have an effect on the long film (300 to 600 m) of the adhesive film 6.
具體而言，第1及第2凸緣部11、12之直徑為250~300 mm，且第1及第2凸緣部11、12間之間隔亦即捲芯軸部2之厚度t為1.00~1.30 mm者，係為特別地具有功效者。 Specifically, the diameters of the first and second flange portions 11 and 12 are 250 to 300 mm, and the interval between the first and second flange portions 11 and 12, that is, the thickness t of the core shaft portion 2 is 1.00. Those who are ~1.30 mm are particularly effective.
於此情形，就確保必要之剛性且謀求凸緣外周部之輕量化觀 點而言，較佳為：將捲芯軸部2之直徑d設定為(第1及第2凸緣部11、12之直徑/2.5)±10%。於此情形，就謀求凸緣外周部之輕量化之觀點而言，較佳為設定為100 mm左右。 In this case, it is necessary to ensure the necessary rigidity and to achieve a lightweight view of the outer peripheral portion of the flange. Preferably, the diameter d of the winding core portion 2 is set to be (the diameter of the first and second flange portions 11 and 12/2.5) ± 10%. In this case, from the viewpoint of reducing the weight of the outer peripheral portion of the flange, it is preferably set to about 100 mm.
此外，就確保必要之剛性且謀求凸緣外周部之輕量化觀點而言，較佳為：將補強部3之直徑D設定為(第1及第2凸緣部11、12之直徑/1.5)±10%。具體而言，較佳之補強部3之直徑D係183~150 mm，但就謀求輕量化之觀點而言，較佳為設定為150 mm左右。 Further, from the viewpoint of securing the necessary rigidity and reducing the weight of the outer peripheral portion of the flange, it is preferable to set the diameter D of the reinforcing portion 3 to be (the diameter of the first and second flange portions 11 and 12/1.5). ±10%. Specifically, the diameter D of the reinforcing portion 3 is preferably 183 to 150 mm. However, from the viewpoint of reducing the weight, it is preferably set to about 150 mm.
此外，就確保必要之剛性且謀求凸緣外周部之輕量化觀點而言，輕量化部4之中心側端部與外周部側端部之厚度之比H1：H2較佳為5：4~3：2，更佳為4：3。具體而言，較佳之中心側之輕量化部4之大小H1係1.90~2.10 mm，較佳之外周部側之輕量化部4之大小H2係1.45~1.55 mm。 In addition, the ratio H 1 :H 2 of the thickness of the center-side end portion and the outer peripheral portion-side end portion of the lightweight portion 4 is preferably 5:4 from the viewpoint of securing the necessary rigidity and reducing the weight of the outer peripheral portion of the flange. ~3:2, more preferably 4:3. Specifically, it is preferable that the size H 1 of the light-weighting portion 4 on the center side is 1.90 to 2.10 mm, and the size H 2 of the light-weighting portion 4 on the outer peripheral side is preferably 1.45 to 1.55 mm.
進一步地，就確保必要之剛性且謀求凸緣外周部之輕量化觀點而言，肋部5之外周部(外側導引部5b)之高度h較佳為0.4~0.5 mm。此外進一步地，就防止接著薄膜往肋部面貼附、與防止接著薄膜往間隙脫落之觀點而言，較佳為：肋部5間之間隔(間隙)C，以相對於接著薄膜6之寬度間隔0.05~0.10 mm之方式設定。 Further, from the viewpoint of securing the necessary rigidity and reducing the weight of the outer peripheral portion of the flange, the height h of the outer peripheral portion (outer guide portion 5b) of the rib 5 is preferably 0.4 to 0.5 mm. Further, from the viewpoint of preventing adhesion of the film to the rib surface and preventing the film from coming off the gap, it is preferable that the interval (gap) C between the ribs 5 is relative to the width of the film 6 Set by the interval of 0.05~0.10 mm.
另一方面，肋部5之內側導引部5a之根數，較佳為：隨著捲盤直徑變大而增加。於適用本發明之範圍內，較佳為8根~24根，更佳為12根~24根。 On the other hand, the number of the inner guide portions 5a of the ribs 5 is preferably increased as the diameter of the reel becomes larger.

一旦肋部5之內側導引部5a之根數少於8根，則恐於捲繞接著薄膜6後以橫置之方式放置或於運送時，於接著薄膜6產生偏移；另一方面，一旦肋部5之內側導引部5a之根數多於24根，則恐於捲繞時產生 接著薄膜6之搭在其上，且同時地，提高接著薄膜6往肋部面附著之風險。相對於捲盤構件1之更大徑化，亦可採用於第1及第2凸緣部11、12之外周部分設置較多之肋部5(內側導引部5a)之構成。 When the number of the inner guiding portions 5a of the ribs 5 is less than eight, it is feared that the film 6 is placed in a transverse manner after being wound around the film 6, or when the film 6 is transported, the film 6 is offset; When the number of the inner guide portions 5a of the rib 5 is more than 24, it is feared that it is generated at the time of winding. The film 6 is then placed over it and, at the same time, increases the risk of adhesion of the film 6 to the rib surface. In addition to the larger diameter of the reel member 1, a configuration in which a large number of ribs 5 (inner guide portions 5a) are provided in the outer peripheral portions of the first and second flange portions 11 and 12 may be employed.

The inner portion of the portion 12 and the portion of the reinforcing portion 3 located on the outer peripheral side of the flange are provided with the lightweight portion 4 which is formed to have a tapered thickness so that the thickness of the reinforcing portion 3 is thin. Therefore, the thickness is limited by a certain thickness. The reinforcing portion 3 can ensure the rigidity of the reel member 1, and can reduce the weight of the outer peripheral portions of the first and second flange portions 11, 12, and thereby prevent the convexity of the reel member 1 from being caused by the weight of the reel member 1 Since the deflection of the outer peripheral portion is increased, the accuracy of the gap between the first and second flange portions 11 and 12 can be improved.
進一步地，於本實施形態中，在第1及第2凸緣部11、12之內側部分，設置有用於引導接著薄膜6之肋部5，而且，肋部5之引導接著薄膜6之面，係以位於相對於捲盤構件1之旋轉方向正交之面上之方式設置，因此可確實地防止捲繞時及拉出時之接著薄膜6之蜿蜒，藉此可確實地防止捲繞時之接著薄膜6之脫落等及拉出時之接著薄膜6之鉤掛或阻塞等。 Further, in the present embodiment, the ribs 5 for guiding the adhesive film 6 are provided on the inner portions of the first and second flange portions 11, 12, and the ribs 5 are guided to the surface of the film 6, Since it is provided so as to be located on the surface orthogonal to the rotation direction of the reel member 1, it is possible to reliably prevent the film 6 from being smashed during winding and pulling out, thereby reliably preventing winding. Then, the film 6 is detached and the like, and the film 6 is hooked or blocked during the drawing.

<評價>將根據實施例及比較例1~4而製作成之捲盤構件(薄膜收容體)分別於室溫之環境下放置24小時，且使用雷射反射式位移計對凸緣外周部之第1及第2凸緣部11、12間之間隙進行測定。其結果表示於表1。此外，於實施例及比較例1~4中，以目視之方式觀察捲繞時之接著薄膜6之狀態(脫落等)。其結果表示於表1。 <Evaluation> The reel members (film storage bodies) which were produced according to the examples and Comparative Examples 1 to 4 were each placed in an environment at room temperature for 24 hours, and were subjected to a laser reflection type displacement gauge to the outer peripheral portion of the flange. The gap between the first and second flange portions 11 and 12 was measured. The results are shown in Table 1. Further, in the examples and the comparative examples 1 to 4, the state (falling off, etc.) of the adhesive film 6 at the time of winding was visually observed. The results are shown in Table 1.
進一步地，對於接著薄膜6，以拉出張力50 g、拉伸速度500 mm/秒之方式以1秒鐘之時間間隔重複進行1秒鐘之拉出，直至最後為止，並以目視之方式觀察拉出時及拉出後之接著薄膜6之狀態(拉出時之鉤掛、阻塞、斷裂)。其結果表示於表1。 Further, for the adhesive film 6, the pull-out was repeated for 1 second at intervals of 1 second with a pull-out tension of 50 g and a tensile speed of 500 mm/sec until the end, and visual observation was performed. The state of the film 6 after the pull-out and the pull-out (hook, block, break when pulled out). The results are shown in Table 1.
<評價結果>由根據表1可知：於未設置補強部及錐狀之輕量化部之比較例1、2之情形，在接著薄膜6之長度為300 m之較短之情形(比較例1)，凸緣外周部之間隙之偏差較小(1.15±0.1 mm)，於捲繞時及拉出時未產生問題，但於接著薄膜6之長度為500 m之長尺寸化之情形(比較例2)，凸緣外周部之間隙之偏差變大(1.15±0.4 mm)，並且於拉出時產生鉤掛、阻塞、及斷裂。 <Evaluation Result> As is clear from Table 1, in the case of Comparative Examples 1 and 2 in which the reinforcing portion and the tapered light-weight portion were not provided, the length of the film 6 was shorter than 300 m (Comparative Example 1). The deviation of the gap at the outer peripheral portion of the flange was small (1.15 ± 0.1 mm), and no problem occurred during winding and pulling, but the length of the film 6 was 500 m long (Comparative Example 2) The deviation of the gap at the outer peripheral portion of the flange becomes large (1.15 ± 0.4 mm), and hooking, blocking, and breaking occur when pulled out.
此外，於在第1及第2凸緣部11、12之內側面形成錐狀之輕量化部4A之另一方面，將肋部5B之高度設定為從捲盤構件1B之內側面高出0.1 mm之比較例3中，即使於第1及第2之凸緣部11、12之徑長為250 mm之情形，凸緣外周部之間隙之偏差較大(1.15±0.2 mm)，而且於捲繞時產生接著薄膜6之捲繞偏移及脫落。 Further, on the other hand, the tapered side weight portion 4A is formed on the inner side surfaces of the first and second flange portions 11 and 12, and the height of the rib portion 5B is set to be 0.1 higher than the inner side surface of the reel member 1B. In Comparative Example 3 of mm, even when the diameters of the first and second flange portions 11 and 12 are 250 mm, the deviation of the gap at the outer peripheral portion of the flange is large (1.15 ± 0.2 mm), and the volume is large. The winding deviation and peeling of the film 6 are caused by the winding.
進一步地，於在第1及第2凸緣部11、12之內側面形成錐狀之輕量化部4A，並且將凸緣外周部之肋部5之高度與實施例同樣地設定 為0.5 mm之比較例4中，可使接著薄膜6之長度長尺寸化為500 m，但凸緣外周部之間隙之偏差較大(1.15±0.2 mm)，而且於拉出時產生鉤掛。 Further, a tapered light-weight portion 4A is formed on the inner side surfaces of the first and second flange portions 11 and 12, and the height of the rib portion 5 at the outer peripheral portion of the flange is set in the same manner as in the embodiment. In Comparative Example 4 of 0.5 mm, the length of the adhesive film 6 was lengthened to 500 m, but the deviation of the gap at the outer peripheral portion of the flange was large (1.15 ± 0.2 mm), and the hook was caught at the time of pulling out.
相對於此，於在第1及第2凸緣部11、12之內側面形成補強部3及錐狀之輕量化部4，並且將凸緣外周部之肋部5之高度設定為0.5 mm之實施例中，即使於接著薄膜6之長度長尺寸化為500 m之情形，凸緣外周部之間隙之偏差較小(1.15±0.1 mm)，尤其是於成型後一刻為1.15±0.1 mm以下。進一步地，於實施例中，於捲繞時及拉出時未產生任何問題。 On the other hand, the reinforcing portion 3 and the tapered light-weight portion 4 are formed on the inner side surfaces of the first and second flange portions 11 and 12, and the height of the rib portion 5 of the outer peripheral portion of the flange is set to 0.5 mm. In the embodiment, even when the length of the film 6 is lengthened to 500 m, the deviation of the gap of the outer peripheral portion of the flange is small (1.15 ± 0.1 mm), especially 1.15 ± 0.1 mm or less at the moment after molding. Further, in the examples, no problem occurred at the time of winding and pulling out.
由以上之結果，可證實：根據本發明，可防止因捲盤構件之本身重量導致凸緣外周部之撓曲，且提高第1及第2凸緣部間之間隙之精度。 From the above results, it was confirmed that the deflection of the outer peripheral portion of the flange due to the weight of the reel member can be prevented, and the accuracy of the gap between the first and second flange portions can be improved.
