Description

彎曲試驗機 Bending test machine

本發明係關於一種彎曲試驗機(folding test machine)，其係使可攜式電話等之基板與有機EL(電致發光)等之撓性顯示器中使用之薄玻璃板與樹脂板彎曲(folding、bending、或bowing)而試驗其耐久度者。 The present invention relates to a folding test machine which bends a thin glass plate and a resin plate used in a flexible display such as a portable telephone or the like, and a flexible display such as an organic EL (electroluminescence). Bending, or bowing) and testing its durability.

最近的可攜式電話日益變薄，其內部之基板自然亦隨之變薄。然而，一旦基板變薄則會有彎曲變得過度而使得基板受損之情況。此處，所謂彎曲，一般而言意味著撓曲成弓形，但因其係規則之彎曲(例如曲率半徑連續平滑地變化之撓曲)，故上述基板等仍有在如此之彎曲下使用的情形。為此，在使用前會進行測試，但是使基板彎曲之時能否正常發揮機能尤其成問題。先前係用手使基板彎曲而判斷其是否適當。然而，若彎曲之曲率半徑不同，則弧長(彎曲部之長度)亦不同，要用手逐一地進行測試並無效率。 Recently, portable phones have become thinner and thinner, and the internal substrate has naturally become thinner. However, once the substrate is thinned, there is a case where the bending becomes excessive and the substrate is damaged. Here, the term "bending" generally means that the bow is bent, but the above-mentioned substrate or the like is still used under such bending because of the regular bending (for example, the curvature of the curvature radius continuously changes smoothly). . For this reason, the test is performed before use, but it is particularly problematic if the substrate is properly functioned when the substrate is bent. It was previously determined by bending the substrate by hand to determine whether it is appropriate. However, if the radius of curvature of the bend is different, the arc length (the length of the bend) is also different, and it is not efficient to perform the test by hand.

不過，若設想利用機械來進行彎曲雖然非不可行，但在做法上仍存在無法實現之情形。 However, it is not feasible to use mechanical means for bending, but there are still situations in which it cannot be achieved.

日本特開2013-057538號中揭示有利用機械進行彎曲之裝置。然而，該文獻中揭示者雖係關於面狀體之彎曲者，但僅為單純地使被試驗體屈曲，而並非使其規則地彎曲者。又，亦並非能夠改變彎曲之曲率半徑而測試者。 A device that bends by a machine is disclosed in Japanese Laid-Open Patent Publication No. 2013-057538. However, the person disclosed in this document is a bender of a planar body, but simply bends the test subject, and does not bend it regularly. Moreover, it is not possible to test the curvature radius of the bend.

本發明係能夠利用機械進行該彎曲試驗者，在該試驗中，即便彎曲之曲率半徑或弧長不同，稍作調整便能夠使機械運作。 The present invention is capable of performing the bending test using a machine in which a slight adjustment makes mechanical operation even if the curvature radius or arc length of the bending is different.

基於上述問題，在本發明之一層面中提供一種彎曲試驗機，其特徵在於：將固定壁與移動壁對向設置在大致四邊形之框架之中，將安裝工件(例如由本試驗機進行試驗之對象物)之安裝部設置成可在兩壁之頂部上分別相對於固定壁與移動壁在鉛垂面內轉動，且在兩安裝部上安裝工件與除工件之外之板簧之各自的兩端而在固定壁與移動壁之間搭設為彎曲狀態，使移動壁相對固定壁遠離、靠近而重複彎曲工件。 Based on the above problems, a bending tester is provided in one aspect of the present invention, characterized in that a fixed wall and a moving wall are disposed opposite each other in a frame of a substantially quadrangular shape, and a workpiece is mounted (for example, an object to be tested by the testing machine) The mounting portion of the object is arranged to be rotatable in the vertical plane with respect to the fixed wall and the moving wall on the top of the two walls, and the respective ends of the workpiece and the leaf spring except the workpiece are mounted on the two mounting portions On the other hand, the fixed wall and the moving wall are placed in a curved state, and the moving wall is repeatedly moved away from and close to the fixed wall to repeatedly bend the workpiece.

在本發明之另一層面中提供一種兩壁可移動的移動壁，使兩方皆遠離、靠近對方，或將一方固定而使另一方遠離、靠近對方之構成。再者，在又一層面中提供一種在工件之兩外側上安裝有與工件長度相同之板簧的構成。 In another aspect of the invention, a movable wall having two walls movable is provided, such that both sides are away from each other, close to each other, or one side is fixed to keep the other side away from the other. Furthermore, in another aspect, a configuration in which a leaf spring having the same length as the workpiece is mounted on both outer sides of the workpiece is provided.

在一層面中，在固定壁與移動壁上以彎曲狀態搭設薄玻璃板與樹脂板等之工件，使移動壁相對固定壁遠離、靠近而重複彎曲工件。此時，存在工件之彎曲曲率半徑等之形狀要素的改變，其可藉由利用使移動壁移動之致動器來改變行程與兩壁之初始位置而實現。又，安裝工件之安裝部由於可相對於移動壁或固定壁在鉛垂面內轉動(可朝對方傾動)，故不會殘存內部應力而亦能夠應對行程變化。進而，亦調整彎曲之速度為佳，此能夠藉由改變致動器之速度而實現。 In one level, a workpiece such as a thin glass plate and a resin plate is placed in a curved state on the fixed wall and the moving wall, and the moving wall is repeatedly bent away from the fixed wall to repeatedly bend the workpiece. At this time, there is a change in the shape element such as the bending radius of curvature of the workpiece, which can be realized by changing the stroke and the initial positions of the two walls by an actuator that moves the moving wall. Further, since the mounting portion for attaching the workpiece can be rotated in the vertical plane with respect to the moving wall or the fixed wall (can be tilted toward the other side), the stroke change can be handled without remaining internal stress. Further, it is preferable to adjust the speed of the bending, which can be achieved by changing the speed of the actuator.

在另一層面中，藉由移動固定壁與移動壁之兩者而能夠將彎曲之形態與曲率半徑此等態樣性與形狀性改變為多種多樣。再者，在又一層面中，由於板簧可按同樣的曲率半徑彎曲，故其能夠模仿工件。 In another aspect, the shape and shape of the curvature can be varied into a variety of shapes by moving both the fixed wall and the moving wall. Furthermore, in another aspect, since the leaf spring can be bent at the same radius of curvature, it can mimic the workpiece.

以下參照圖式說明本發明之實施形態。圖1係本發明之試驗機之立體圖。在大致箱型之框架1中，分別在一端側大致垂直地設置固定壁2，在靠近中央處大致垂直地設置移動壁3，且使其等對向。此處，固定壁2由螺栓等固定件而固定於框架。移動壁3係以藉由外力而靠近或遠離固定壁2側之方式設置為可移動。因此，在移動壁3之下垂部3a設置能夠連接缸體等致動器之連接部13，在連接部13上連接致動器(圖示省略)。致動器可應用任何已知之裝置，亦可為往復運動之活塞。此外，圖1亦可謂圖示彎曲試驗機之產生彎曲之主要構成部分。 Embodiments of the present invention will be described below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a testing machine of the present invention. In the frame 1 of the substantially box type, the fixed wall 2 is provided substantially perpendicularly on one end side, and the moving wall 3 is provided substantially perpendicularly to the center, and is opposed to each other. Here, the fixed wall 2 is fixed to the frame by a fixing member such as a bolt. The moving wall 3 is provided to be movable in such a manner as to be close to or away from the side of the fixed wall 2 by an external force. Therefore, the connecting portion 13 capable of connecting an actuator such as a cylinder is provided in the lower hanging portion 3a of the moving wall 3, and an actuator (not shown) is connected to the connecting portion 13. The actuator can be applied to any known device or a reciprocating piston. In addition, FIG. 1 can also be said to be a main component of the bending of the bending tester.

而，固定壁2之固定與移動壁3之移動可由周知之構造實現。在本實施例中，在由框架構件構成之兩側具備一對導軌14，該框架構件係以從框架1之一端側朝對向之另一端側、沿相對於固定壁2大致垂直的方向延伸之方式，連接框架1之一端側以及另一端側。於各個導軌14上安裝可在各個導軌14上移動之滑塊15。在各個導軌14上之位於對向位置上之滑塊15上，搭設連接於固定壁2之桿16。同樣的，在每個導軌14上之位於對向位置之滑塊15上，搭設連接於移動壁3之桿17。然因固定壁2不相對於框架1移動，故將支架18從桿16下垂至兩側側面之外側，以螺釘19等將該支架18固定於框架1上。藉此，若使移動壁3之致動器運作，則移動壁3以相對於固定壁2遠離、靠近之方式移動。此外，改變固定壁2之位置時，可調整螺釘19等而改變支架18之位置。 However, the fixing of the fixed wall 2 and the movement of the moving wall 3 can be realized by a well-known construction. In the present embodiment, a pair of guide rails 14 are provided on both sides of the frame member, and the frame members extend in a direction substantially perpendicular to the fixed wall 2 from the one end side of the frame 1 toward the opposite end side. In this manner, one end side and the other end side of the frame 1 are connected. A slider 15 movable on each of the guide rails 14 is mounted on each of the guide rails 14. On the slider 15 at the opposite position on each of the guide rails 14, a rod 16 connected to the fixed wall 2 is erected. Similarly, a rod 17 connected to the moving wall 3 is erected on the slider 15 at the opposite position on each of the guide rails 14. However, since the fixed wall 2 does not move relative to the frame 1, the bracket 18 is suspended from the rod 16 to the outer side of the both side faces, and the bracket 18 is fixed to the frame 1 by screws 19 or the like. Thereby, when the actuator of the moving wall 3 is operated, the moving wall 3 moves away from and close to the fixed wall 2. Further, when the position of the fixed wall 2 is changed, the screw 19 or the like can be adjusted to change the position of the bracket 18. Set.

在桿16上，在其長度方向上並排豎立一對大致垂直於桿16之板狀之柱，於該等柱上固定頂板22。頂板22與桿16大致平行地朝長度方向延伸，面向移動壁3之內側端部較對向之外側端部長，在俯視觀察下呈梯形。於該內側端部設置鉸鏈9。同樣的，在桿17上，在其長度方向上並排豎立著一對大致垂直於桿17之板狀之柱，於該等柱上固定頂板23。頂板23與桿17大致平行地朝長度方向延伸，面向固定壁2之內側端部較對向之外側端部長，在俯視觀察下呈梯形。於該內側端部設置鉸鏈10。 On the rod 16, a pair of plate-like columns substantially perpendicular to the rod 16 are erected side by side in the longitudinal direction thereof, and the top plate 22 is fixed on the columns. The top plate 22 extends in the longitudinal direction substantially in parallel with the rod 16, and faces the inner end portion of the moving wall 3 with respect to the outer side end, and has a trapezoidal shape in plan view. A hinge 9 is provided at the inner end portion. Similarly, on the rod 17, a pair of plate-like columns substantially perpendicular to the rod 17 are erected side by side in the longitudinal direction thereof, and the top plate 23 is fixed to the columns. The top plate 23 extends in the longitudinal direction substantially in parallel with the rod 17, and faces the outer end of the fixed wall 2 toward the outer end, and has a trapezoidal shape in plan view. A hinge 10 is provided at the inner end portion.

將具有大致矩形之板狀之工件4分別架設於移動壁3與固定壁2之間(以下，在平面觀察下，將架設方向之尺寸稱為工件4之長度，將與架設方向大致垂直的方向稱為工件4之寬度)。此時對移動壁3之安裝係將工件夾在安裝部6與按壓板8之間而安裝，該安裝部6藉由鉸鏈10而可在鉛垂面內旋轉地安裝於設置在移動壁3之頂部(頂端)側之頂板23，該按壓板8固定於安裝部6。同樣的，對固定壁2之安裝係將工件夾在安裝部5與按壓板7之間而安裝，該安裝部5藉由鉸鏈9而可在鉛垂面內旋轉地安裝於設置在固定壁2之頂部(頂端)側之頂板22，該按壓板7固定於安裝部5。亦即，分別利用鉸鏈9、10而可旋轉地安裝之安裝部5、6，隨著固定壁2與移動壁3之遠離靠近，而可朝對方之方向傾動(或轉動)。由於工件4之兩端安裝在兩安裝部5、6，故隨著因工件4撓曲而產生之曲率半徑不同，工件4之兩端之傾斜角度亦變得不同。安裝部5、6因能夠傾動(或轉動)，故能夠應對該不同。又，係為了能夠儘可能地減少在工件4之內部產生之局部應力或應力集中。 A workpiece 4 having a substantially rectangular plate shape is respectively placed between the moving wall 3 and the fixed wall 2 (hereinafter, the dimension of the mounting direction is referred to as the length of the workpiece 4 in a plan view, and is substantially perpendicular to the mounting direction. Called the width of the workpiece 4). At this time, the mounting of the moving wall 3 is performed by sandwiching the workpiece between the mounting portion 6 and the pressing plate 8, and the mounting portion 6 is rotatably attached to the moving wall 3 in the vertical plane by the hinge 10. A top plate 23 on the top (top) side, the pressing plate 8 is fixed to the mounting portion 6. Similarly, the mounting of the fixed wall 2 is performed by sandwiching a workpiece between the mounting portion 5 and the pressing plate 7, and the mounting portion 5 is rotatably mounted in the vertical plane by the hinge 9 to be disposed on the fixed wall 2 The top plate 22 on the top (top) side is fixed to the mounting portion 5. That is, the mounting portions 5, 6 rotatably mounted by the hinges 9, 10, respectively, can be tilted (or rotated) in the direction of the other side as the fixed wall 2 and the moving wall 3 are moved away from each other. Since both ends of the workpiece 4 are attached to the two mounting portions 5 and 6, the inclination angles of the both ends of the workpiece 4 are different as the radius of curvature due to the deflection of the workpiece 4 is different. Since the mounting portions 5 and 6 can be tilted (or rotated), the difference can be handled. Also, in order to minimize the local stress or stress concentration generated inside the workpiece 4.

該鉸鏈9、10經設法減輕重量而減少了轉動之阻力。又，因工件4具有重量，故在移動壁3與固定壁2僅分開接近工件4長度之距離時，工件4亦呈稍微朝下下垂之彎曲形狀。圖3A及圖3B係主要部分之側視圖。以彈簧11將安裝部5、6朝下方拉。由於設為每次彎曲時安裝部5、6因慣性而不會抬升至水平以上，故能夠因應動作之高速化。又，在利用本試驗機之試驗中，移動壁3不宜遠離固定壁2多於架設工件4時之距離。否則會有對工件4施加張力之虞。 The hinges 9, 10 are designed to reduce weight and reduce the resistance to rotation. Further, since the workpiece 4 has a weight, when the moving wall 3 and the fixed wall 2 are separated from each other only by the distance of the length of the workpiece 4, the workpiece 4 also has a curved shape which is slightly downward. 3A and 3B are side views of the main part Figure. The mounting portions 5, 6 are pulled downward by the spring 11. Since the mounting portions 5 and 6 are not raised to the level or higher due to the inertia at each bending, the speed of the operation can be increased. Further, in the test using the test machine, the moving wall 3 should not be farther away from the fixed wall 2 than when the workpiece 4 was placed. Otherwise, there will be a tension applied to the workpiece 4.

又，在固定於安裝部5、6上之除對向之2個端部以外的工件4之側端部之兩外側上，將與工件4長度相同之板簧12以螺栓20鎖止並架設在安裝部5、6上。板簧12具有彎曲時可成同樣的曲率半徑之性質，藉此，安裝部5、6因同樣的曲率半徑而以最合適的角度傾動(或轉動)。而且，由於以安裝部5、6之傾動角度(或傾斜角度)安裝工件，故工件亦以同樣的曲率半徑彎曲。即，能夠使工件4之彎曲仿照板簧12之彎曲，且藉由在工件4之兩外側上設置板簧12，故工件4能夠同樣地彎曲。此時，板簧12具有較工件4更高之耐久性為佳。另外，板簧12之對抗彎曲之阻力以較工件4之阻力大為佳。 Further, the leaf springs 12 having the same length as the workpiece 4 are locked and erected by bolts 20 on both outer sides of the side end portions of the workpieces 4 which are fixed to the mounting portions 5 and 6 except for the two opposite end portions. On the mounting portions 5, 6. The leaf spring 12 has the property of having the same radius of curvature when bent, whereby the mounting portions 5, 6 are tilted (or rotated) at an optimum angle due to the same radius of curvature. Further, since the workpiece is attached at the tilting angle (or the inclination angle) of the mounting portions 5, 6, the workpiece is also bent at the same radius of curvature. That is, the bending of the workpiece 4 can be modeled by the bending of the leaf spring 12, and by providing the leaf spring 12 on both outer sides of the workpiece 4, the workpiece 4 can be bent in the same manner. At this time, the leaf spring 12 has a higher durability than the workpiece 4. In addition, the resistance of the leaf spring 12 against bending is preferably greater than the resistance of the workpiece 4.

上述係本發明之基本形態，但亦存在其他的各種改變。其最大的改變係使固定壁2與移動壁3同樣地移動。此由圖4、圖5顯示，廢除固定壁2之支架18與螺釘19並在其下垂部2a上形成連接部21，且在該連接部21連接致動器。藉此，若同時使二個致動器運作，則固定壁2、移動壁3一同移動。此時，藉由改變兩者之移動速度、行程或方向而能謀求試驗形態之多樣性。 The above is the basic form of the invention, but there are other variations. The biggest change is that the fixed wall 2 moves in the same manner as the moving wall 3. 4 and 5, the bracket 18 of the fixed wall 2 is abolished and the connecting portion 21 is formed on the hanging portion 2a thereof, and the actuator is connected to the connecting portion 21. Thereby, if the two actuators are operated at the same time, the fixed wall 2 and the moving wall 3 move together. At this time, the diversity of the test form can be achieved by changing the moving speed, stroke or direction of the two.

再者，亦能夠進行將一者鎖定(亦可改變鎖定位置)而僅移動另一者之試驗。 Furthermore, it is also possible to perform a test in which one is locked (and the locked position can also be changed) and only the other is moved.

再者，本發明之實施例即彎曲試驗機能夠使工件4大幅度彎曲。例如，如圖6所示，由於安裝部5、6大致垂直地朝向下方，且工件4接觸於固定壁2及移動壁3，故可將工件4之彎曲控制成U字形。另外，在耐久試驗中，即便在工件4破損之情形下，固定壁2及移動壁3亦能夠防止碎片之飛散。例如，固定壁2及移動壁3可具有工件4的長度之大致一半的長度。 Further, the bending tester according to the embodiment of the present invention can greatly bend the workpiece 4. For example, as shown in FIG. 6, since the mounting portions 5, 6 are substantially vertically downward and the workpiece 4 is in contact with the fixed wall 2 and the moving wall 3, the bending of the workpiece 4 can be controlled into a U shape. Further, in the endurance test, even in the case where the workpiece 4 is broken, the fixed wall 2 and the moving wall 3 can prevent the scattering of the fragments. For example, the fixed wall 2 and the moving wall 3 may have the length of the workpiece 4 About half the length.
