Description
本發明係關於一種用於測定在將貼合於顯示面板之表面之保護薄膜剝離時之帶電電壓的帶電電壓測定裝置及帶電電壓測定方法。The present invention relates to a charged voltage measuring device and a charged voltage measuring method for measuring a charged voltage when a protective film attached to a surface of a display panel is peeled off.
於顯示裝置中使用之液晶面板、有機EL(Electro Luminescence：電致發光)面板等顯示面板上，通常，為了保護其表面而貼合有保護薄膜。顯示面板係於貼合有保護薄膜之狀態下輸送，於製成顯示裝置之後，自顯示面板之表面剝離保護薄膜。In a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel used in a display device, a protective film is usually attached to protect the surface. The display panel is conveyed in a state in which a protective film is attached, and after the display device is manufactured, the protective film is peeled from the surface of the display panel.
於此種顯示面板中安裝有很多電氣零件。例如，於液晶顯示面板中設有TFT(Thin Film Transistor：薄膜電晶體)、用於驅動TFT之驅動器IC(Integrated Circuit：積體電路)等。因此，於使保護薄膜自顯示面板之表面剝離時，存在TFT、驅動器IC等電氣零件因顯示面板之表面產生的帶電電壓而被破壞的風險。A lot of electrical parts are installed in this display panel. For example, a liquid crystal display panel is provided with a TFT (Thin Film Transistor), a driver IC (Integrated Circuit) for driving the TFT, and the like. Therefore, when the protective film is peeled from the surface of the display panel, there is a risk that electrical components such as TFTs and driver ICs are damaged due to a charged voltage generated on the surface of the display panel.
因此，提出一種保護薄膜剝離裝置，該保護薄膜剝離裝置能夠藉由利用帶電檢測部來檢測顯示面板之表面電位並根據檢測出之表面電位來控制保護薄膜之剝離速度，從而防止面板表面之表面電位上升(例如參照下述專利文獻1)。 [現有技術文獻] [專利文獻]Therefore, a protective film peeling device is proposed. The protective film peeling device can detect the surface potential of the display panel by using a charged detection unit and control the peeling speed of the protective film according to the detected surface potential, thereby preventing the surface potential of the panel surface. Increase (for example, refer to Patent Document 1 below). [Prior Art Literature] [Patent Literature]
[專利文獻1]：日本特開2008-51906號公報[Patent Document 1]: Japanese Patent Application Laid-Open No. 2008-51906
[發明所欲解決之問題][Problems to be solved by the invention]
然而，於上述專利文獻1所公開之構成中，帶電檢測部配置於顯示面板之與保護薄膜被剝離之側之面相反之側。因此，存在無法準確地測定顯示面板之保護薄膜被剝離的一側的面的帶電電壓之問題。However, in the configuration disclosed in the above-mentioned Patent Document 1, the charge detection unit is disposed on the side of the display panel opposite to the side from which the protective film is peeled off. Therefore, there is a problem in that it is impossible to accurately measure the charging voltage of the surface on which the protective film of the display panel is peeled off.
另外，於如上述專利文獻1所公開般之構成中，具有用於使帶電檢測部移動之第1移動部，一邊利用該第1移動部使帶電檢測部移動一邊進行帶電電壓之測定。因此，存在帶電檢測部與顯示面板之間的距離容易產生偏差而使測定精度進一步變差之問題。In addition, the configuration disclosed in the above-mentioned Patent Document 1 includes a first moving section for moving the charging detection section, and measures the charging voltage while moving the charging detection section using the first moving section. Therefore, there is a problem that the distance between the electrification detection section and the display panel is likely to vary and the measurement accuracy is further deteriorated.
本發明係鑒於上述情況而完成，其目的在於，提供能夠精度良好地測定顯示面板之表面之帶電電壓的帶電電壓測定裝置及帶電電壓測定方法。 [解決問題之技術手段]The present invention has been made in view of the above circumstances, and an object thereof is to provide a charged voltage measuring device and a charged voltage measuring method capable of accurately measuring a charged voltage on a surface of a display panel. [Technical means to solve the problem]
(1)本發明之帶電電壓測定裝置係用於測定將貼合於顯示面板之表面之保護薄膜剝離時之帶電電壓者，且具備保持部、剝離機構、以及測定器。上述保持部保持上述顯示面板。上述剝離機構藉由使上述保持部沿特定之移動方向移動，而使上述保護薄膜自上述顯示面板之表面剝離。上述測定器於較自上述顯示面板之表面剝離上述保護薄膜之位置更為上述移動方向的下游側，以與上述表面對向之方式固定於規定位置，測定上述表面之帶電電壓。(1) The charged voltage measuring device of the present invention is a device for measuring a charged voltage when a protective film attached to a surface of a display panel is peeled off, and includes a holding portion, a peeling mechanism, and a measuring device. The holding portion holds the display panel. The peeling mechanism moves the holding portion in a specific moving direction to peel the protective film from the surface of the display panel. The measuring device is fixed to a predetermined position on the downstream side in the moving direction from a position where the protective film is peeled from the surface of the display panel, and measures the charged voltage on the surface.
根據此種構成，藉由使保持顯示面板之保持部沿特定之移動方向移動，從而自顯示面板之表面剝離保護薄膜。藉此，能夠一邊將自顯示面板之表面剝離保護薄膜的位置(剝離位置)保持一定，一邊剝離保護薄膜。因而，藉由不使測定器移動並以與較剝離位置更為下游側對向之方式將測定器固定於規定位置，能夠精度良好地測定顯示面板之要剝離保護薄膜之側之面的帶電電壓。According to this configuration, the protective film is peeled from the surface of the display panel by moving the holding portion holding the display panel in a specific moving direction. Thereby, it is possible to peel off the protective film while maintaining a certain position (peeling position) at which the protective film is peeled from the surface of the display panel. Therefore, the measurement voltage of the side of the display panel on which the protective film is to be peeled off can be accurately measured by fixing the tester at a predetermined position so as not to move the tester and facing the downstream side from the peeling position. .
(2)較佳為，使上述保護薄膜自上述顯示面板之表面剝離時之上述保持部之移動速度為10～100 m/min。(2) Preferably, the moving speed of the holding portion when the protective film is peeled from the surface of the display panel is 10 to 100 m / min.
根據此種構成，由於能夠一邊使保持部以適當之移動速度移動一邊使保護薄膜自顯示面板之表面剝離，因此，測定結果不易產生偏差，能夠進一步精度良好地測定顯示面板之表面之帶電電壓。According to this configuration, the protective film can be peeled from the surface of the display panel while the holding portion is moved at an appropriate moving speed. Therefore, the measurement results are less likely to vary, and the charged voltage on the surface of the display panel can be further accurately measured.
(3)較佳為，上述測定器係以隔開5～50 mm之間隔而與上述顯示面板之表面對向之方式固定於規定位置。(3) Preferably, the measuring device is fixed at a predetermined position so as to face the surface of the display panel at an interval of 5 to 50 mm.
根據此種構成，一邊將測定器固定於適當的位置來測定帶電電壓一邊使保護薄膜自顯示面板之表面剝離，因此測定結果不易產生偏差，能夠進一步精度良好地測定顯示面板之表面之帶電電壓。According to this configuration, the protective film is peeled from the surface of the display panel while the measuring device is fixed at an appropriate position to measure the charged voltage. Therefore, the measurement results are less likely to vary, and the charged voltage on the surface of the display panel can be further accurately measured.
(4)亦可為，上述剝離機構具有使上述保持部以經設定之移動速度沿上述移動方向移動之移動機構。(4) The peeling mechanism may include a moving mechanism that moves the holding portion in the moving direction at a set moving speed.
根據此種構成，能夠使保持部以設定好之移動速度精度良好地移動。因而，測定結果不易產生偏差，能夠進一步精度良好地測定顯示面板之表面之帶電電壓。According to this configuration, the holding portion can be moved accurately with the set moving speed. Therefore, the measurement results are less likely to vary, and the charged voltage on the surface of the display panel can be further accurately measured.
(5)亦可為，上述保持部沿上述移動方向移動自如。該情形時，亦可為，上述剝離機構利用自上述顯示面板之表面剝離上述保護薄膜時作用於上述顯示面板之力，使上述保持部沿上述移動方向移動。(5) The holding portion may move freely in the moving direction. In this case, the peeling mechanism may move the holding portion in the moving direction by using a force acting on the display panel when the protective film is peeled from a surface of the display panel.
根據此種構成，藉由自顯示面板之表面連續地剝離保護薄膜，能夠利用剝離保護薄膜時作用於顯示面板之力來使保持部穩定地移動。因而，即使為不具有移動機構之簡單的構成，亦能夠使測定結果不易產生偏差，能夠精度良好地測定顯示面板之表面之帶電電壓。According to this configuration, by continuously peeling the protective film from the surface of the display panel, the holding portion can be stably moved by the force acting on the display panel when the protective film is peeled. Therefore, even if it has a simple configuration without a moving mechanism, it is possible to make measurement results less likely to vary, and to accurately measure the charged voltage on the surface of the display panel.
(6)本發明提供一種帶電電壓測定方法，其係用於測定將貼合於顯示面板之表面之保護薄膜剝離時之帶電電壓者，且包含剝離步驟及測定步驟。於上述剝離步驟中，藉由使保持上述顯示面板之保持部沿特定之移動方向移動，而使上述保護薄膜自上述顯示面板之表面剝離。於測定步驟中，於較自上述顯示面板之表面剝離上述保護薄膜之位置更為上述移動方向的下游側，藉由以與上述表面對向之方式固定於規定位置的測定器，測定上述表面之帶電電壓。 [發明之效果](6) The present invention provides a method for measuring a charged voltage, which is used to measure a charged voltage when a protective film attached to a surface of a display panel is peeled off, and includes a peeling step and a measuring step. In the above-mentioned peeling step, the protective film is peeled from the surface of the display panel by moving the holding portion holding the display panel in a specific moving direction. In the measurement step, the position of the surface is measured on the downstream side in the moving direction from the position where the protective film is peeled from the surface of the display panel, and the surface of the surface is measured by a measuring device fixed to a predetermined position so as to face the surface. Live voltage. [Effect of the invention]
根據本發明，藉由以使測定器不移動並與剝離位置對向之方式將測定器固定於規定位置，能夠精度良好地測定顯示面板之要剝離保護薄膜之側之面的帶電電壓。According to the present invention, by fixing the measuring device at a predetermined position so that the measuring device does not move and faces the peeling position, it is possible to accurately measure the charged voltage of the surface of the display panel on the side where the protective film is to be peeled off.
1. 帶電電壓測定裝置之整體構成 圖1係表示本發明之一個實施形態之帶電電壓測定裝置1之構成例的概略側視圖。另外，圖2係帶電電壓測定裝置1之概略俯視圖。該帶電電壓測定裝置1係用於測定在將貼合於顯示面板2之表面21的保護薄膜22剝離時於該表面21產生的電壓(帶電電壓)的裝置。帶電電壓測定裝置1中設有保持部11、剝離機構12以及測定器13等。1. Overall Configuration of Charged Voltage Measuring Device FIG. 1 is a schematic side view showing a configuration example of a charged voltage measuring device 1 according to an embodiment of the present invention. FIG. 2 is a schematic plan view of the charged voltage measuring device 1. The charged voltage measuring device 1 is a device for measuring a voltage (charged voltage) generated on the surface 21 of the display panel 2 when the protective film 22 attached to the surface 21 of the display panel 2 is peeled off. The charged voltage measuring device 1 is provided with a holding portion 11, a peeling mechanism 12, a measuring device 13, and the like.
顯示面板2例如為具有偏振板(未圖示)之液晶面板。為了保護偏振板之表面，於顯示面板2上經由黏著劑(未圖示)貼合有保護薄膜22。另外，於液晶面板上安裝有TFT、驅動器IC等電氣零件(未圖示)。The display panel 2 is, for example, a liquid crystal panel including a polarizing plate (not shown). In order to protect the surface of the polarizing plate, a protective film 22 is bonded to the display panel 2 via an adhesive (not shown). In addition, electrical components (not shown) such as a TFT and a driver IC are mounted on the liquid crystal panel.
於自顯示面板2之表面21剝離保護薄膜22時，因靜電而使表面21帶電，存在電氣零件因該帶電電壓而被破壞的風險。因此，若使用本實施形態之帶電電壓測定裝置1來測定顯示面板2之表面21的帶電電壓，則能夠確認是否產生容許值以上的帶電電壓。When the protective film 22 is peeled from the surface 21 of the display panel 2, the surface 21 is charged by static electricity, and there is a risk that electrical parts are damaged due to the charged voltage. Therefore, if the charged voltage of the surface 21 of the display panel 2 is measured using the charged voltage measuring device 1 of this embodiment, it can be confirmed whether or not a charged voltage greater than an allowable value is generated.
顯示面板2由保持部11保持。保持部11例如為平板狀之載置台，保持部11之上表面構成用於載置並保持顯示面板2的之持面111。於保持部11之底部設有複數個輥112。保持部11能夠藉由複數個輥112之旋轉而沿特定之移動方向D1移動。The display panel 2 is held by a holding portion 11. The holding portion 11 is, for example, a flat-shaped mounting table, and an upper surface of the holding portion 11 constitutes a holding surface 111 for placing and holding the display panel 2. A plurality of rollers 112 are provided on the bottom of the holding portion 11. The holding portion 11 can move in a specific moving direction D1 by the rotation of the plurality of rollers 112.
顯示面板2的與保護薄膜22側相反之側的面載置於保持部11之保持面111上。保持面111例如由沿水平方向延伸之平坦面構成。於保持部11設有用於在保持面111上固定顯示面板2之固定機構(未圖示)，在自顯示面板2剝離保護薄膜22時，能夠防止顯示面板2與保持面111分離或顯示面板2於保持面111上發生偏移。作為固定機構，可例示使顯示面板2吸附於保持面111上之吸附機構等，但並不限於此。The surface of the display panel 2 opposite to the protective film 22 side is placed on the holding surface 111 of the holding portion 11. The holding surface 111 is, for example, a flat surface extending in the horizontal direction. The holding portion 11 is provided with a fixing mechanism (not shown) for fixing the display panel 2 on the holding surface 111. When the protective film 22 is peeled from the display panel 2, the display panel 2 can be prevented from being separated from the holding surface 111 or the display panel 2. An offset occurs on the holding surface 111. Examples of the fixing mechanism include an adsorption mechanism that causes the display panel 2 to be adsorbed on the holding surface 111, but the invention is not limited thereto.
剝離機構12係用於自顯示面板2之表面21剝離保護薄膜22之機構。於剝離機構12中設有剝離旋轉桿121、角度變更輥122以及捲取輥123等。剝離旋轉桿121、角度變更輥122以及捲取輥123分別由框架(未圖示)以能夠旋轉之方式保持，保持部11被設置為能夠相對於該框架相對地移動。The peeling mechanism 12 is a mechanism for peeling the protective film 22 from the surface 21 of the display panel 2. The peeling mechanism 12 is provided with a peeling rotation lever 121, an angle changing roller 122, a take-up roller 123, and the like. The peeling rotation lever 121, the angle changing roller 122, and the take-up roller 123 are each rotatably held by a frame (not shown), and the holding portion 11 is provided to be relatively movable with respect to the frame.
本實施形態中，剝離機構12使保持部11沿特定之移動方向D1移動，由此能夠使保護薄膜22自顯示面板2之表面21剝離。上述移動方向D1例如為相對於保持面111平行的方向，於該示例中為水平方向。In this embodiment, the peeling mechanism 12 can peel the protective film 22 from the surface 21 of the display panel 2 by moving the holding portion 11 in a specific moving direction D1. The moving direction D1 is, for example, a direction parallel to the holding surface 111, and is a horizontal direction in this example.
保護薄膜22首先於端緣部221自顯示面板2之表面21剝離，且藉由將該端緣部221向剝離方向D2牽引，而自表面21緩慢地剝離(參照圖2)。剝離方向D2例如為於圖2所示之俯視下相對於保持部11之移動方向D1相反的方向。自顯示面板2之表面21剝離保護薄膜22的位置(剝離位置P)、即要剝離之保護薄膜22之背面與顯示面板2之表面21的交界位置係沿著相對於剝離方向D2正交之方向呈直線狀延伸。The protective film 22 is first peeled from the surface 21 of the display panel 2 at the edge portion 221, and is slowly peeled from the surface 21 by pulling the edge portion 221 in the peeling direction D2 (see FIG. 2). The peeling direction D2 is, for example, a direction opposite to the moving direction D1 of the holding portion 11 in a plan view shown in FIG. 2. The position at which the protective film 22 is peeled from the surface 21 of the display panel 2 (peeling position P), that is, the boundary position between the back surface of the protective film 22 to be peeled and the surface 21 of the display panel 2 is in a direction orthogonal to the peeling direction D2 Extends straight.
剝離旋轉桿121、角度變更輥122以及捲取輥123各自沿相對於剝離方向D2正交之方向延伸。保護薄膜22之端緣部221經由例如由其他薄膜或帶等構成之連接構件23連接於捲取輥123，藉由捲取輥123旋轉而被捲取於捲取輥123之外周面。藉此，能夠一邊自顯示面板2之表面21連續地剝離保護薄膜22，一邊以對保護薄膜22賦予張力之狀態將保護薄膜22捲取於捲取輥123。The peeling rotation lever 121, the angle changing roller 122, and the take-up roller 123 each extend in a direction orthogonal to the peeling direction D2. The edge portion 221 of the protective film 22 is connected to the take-up roll 123 via a connection member 23 made of, for example, another film or a tape, and is wound around the outer peripheral surface of the take-up roll 123 by rotating the take-up roll 123. Thereby, while the protective film 22 is continuously peeled from the surface 21 of the display panel 2, the protective film 22 can be wound on the take-up roller 123 in a state where tension is applied to the protective film 22.
剝離旋轉桿121被保持為旋轉自如，且於剝離位置P與捲取輥123之間接觸於自顯示面板2之表面21剝離的保護薄膜22之表面。因此，利用來自由捲取輥123捲取之保護薄膜22所作用之力，剝離旋轉桿121一邊旋轉一邊輸送保護薄膜22。The peeling rotation lever 121 is held to be rotatable, and is in contact with the surface of the protective film 22 peeled from the surface 21 of the display panel 2 between the peeling position P and the take-up roller 123. Therefore, the protective film 22 is conveyed while the peeling rotation lever 121 is rotated by the force from the protective film 22 wound by the winding roller 123.
角度變更輥122被保持為旋轉自如，且於剝離旋轉桿121與捲取輥123之間接觸於自顯示面板2之表面21剝離之保護薄膜22的背面。該角度變更輥122如圖1之虛線所示被保持為能夠平行移動。因而，藉由使角度變更輥122之位置平行移動，能夠改變於剝離位置P被剝離之保護薄膜22之角度。藉此，能夠根據保護薄膜22之種類而以適當的角度使保護薄膜22自顯示面板2之表面21剝離。然亦能夠省略角度變更輥122。The angle changing roller 122 is maintained to be freely rotatable, and is in contact with the back surface of the protective film 22 peeled from the surface 21 of the display panel 2 between the peeling rotation lever 121 and the take-up roller 123. The angle changing roller 122 is held so as to be able to move in parallel as shown by a broken line in FIG. 1. Therefore, by moving the position of the angle changing roller 122 in parallel, the angle of the protective film 22 peeled at the peeling position P can be changed. Thereby, the protective film 22 can be peeled from the surface 21 of the display panel 2 at an appropriate angle depending on the kind of the protective film 22. However, the angle changing roller 122 can be omitted.
測定器13以與保護薄膜22剝離後之顯示面板2之表面21對向之方式配置，測定該表面21之帶電電壓。具體而言，測定器13位於較剝離位置P更為移動方向D1之下游側的位置。測定器13之位置較佳為配置於儘可能靠近剝離位置P但不會干擾到要剝離之保護薄膜22的位置。測定器13相對於剝離位置P固定於規定位置。即，測定器13以於測定中不移動之方式固定於預先確定的一定位置。此外，測定器13亦可為於非測定時能夠移動的構成。The measuring device 13 is disposed so as to face the surface 21 of the display panel 2 after the protective film 22 is peeled off, and measures the charging voltage of the surface 21. Specifically, the measuring device 13 is located further downstream than the peeling position P in the moving direction D1. The position of the measuring device 13 is preferably located as close to the peeling position P as possible without disturbing the protective film 22 to be peeled. The measuring device 13 is fixed at a predetermined position with respect to the peeling position P. That is, the measuring device 13 is fixed to a predetermined fixed position so as not to move during the measurement. The measuring device 13 may be configured to be movable during non-measurement.
於該帶電電壓測定裝置1中，在保護薄膜22被賦予張力之狀態下，如圖1及圖2中虛線所示，使保持顯示面板2之保持部11沿特定之移動方向D1移動，從而自顯示面板2之表面21剝離保護薄膜22(剝離步驟)。藉此，能夠將自顯示面板2之表面21剝離保護薄膜22的位置(剝離位置P)保持為一定並剝離保護薄膜22。In this charged voltage measuring device 1, in a state where the protective film 22 is given tension, as shown by the dotted lines in FIG. 1 and FIG. 2, the holding portion 11 holding the display panel 2 is moved in a specific moving direction D1, so that The protective film 22 is peeled from the surface 21 of the display panel 2 (peeling step). Thereby, the position where the protective film 22 is peeled off from the surface 21 of the display panel 2 (peeling position P) can be kept constant, and the protective film 22 can be peeled off.
此時，於較剝離位置P更為移動方向D1的下游側，藉由測定器13測定顯示面板2之表面21之帶電電壓(測定步驟)。因此，藉由不使測定器13移動並以與較剝離位置P更為下游側的位置對向之方式將測定器13固定於規定位置，能夠精度良好地測定顯示面板2之要剝離保護薄膜22之側之面(表面21)的帶電電壓。At this time, the charging voltage on the surface 21 of the display panel 2 is measured by the measuring device 13 on the downstream side in the moving direction D1 than the peeling position P (measurement step). Therefore, the measurement device 13 can be accurately measured to prevent the protective film 22 to be peeled off of the display panel 2 by fixing the measurement device 13 at a predetermined position so as not to move the measurement device 13 so as to face the position further downstream than the separation position P. The charged voltage on the side (surface 21).
測定器13例如以隔開5 mm～50 mm之間隔與顯示面板2之表面21對向之方式固定於規定位置。藉此，能夠一邊將測定器13固定於適當的位置來測定帶電電壓，一邊使保護薄膜22自顯示面板2之表面21剝離，因此測定結果不易產生偏差，能夠進一步精度良好地測定顯示面板2之表面21的帶電電壓。The measuring device 13 is fixed at a predetermined position so as to face the surface 21 of the display panel 2 with an interval of 5 mm to 50 mm, for example. Thereby, the protective film 22 can be peeled off from the surface 21 of the display panel 2 while the measuring device 13 is fixed at an appropriate position to measure the charged voltage. Therefore, the measurement results are less likely to vary, and the display panel 2 can be further accurately measured. The charged voltage of the surface 21.
該示例中，顯示面板2之朝向相對於移動方向D1傾斜。即，矩形形狀之顯示面板2之長邊方向及短邊方向分別相對於移動方向D1傾斜。其結果，保護薄膜22被從位於與顯示面板2之角部相對應的位置之端緣部221剝離。然而，並不限於此種構成，亦可為如下之構成，例如藉由使顯示面板2之長邊方向或短邊方向相對於移動方向D1平行地配置，從而自沿著顯示面板之長度或短邊延伸之端緣部剝離保護薄膜22。In this example, the orientation of the display panel 2 is inclined with respect to the moving direction D1. That is, the long-side direction and the short-side direction of the rectangular display panel 2 are inclined with respect to the moving direction D1, respectively. As a result, the protective film 22 is peeled from the edge portion 221 located at a position corresponding to the corner portion of the display panel 2. However, it is not limited to such a configuration, and may be a configuration in which, for example, the long or short side direction of the display panel 2 is arranged in parallel with the moving direction D1 so as to extend along the length or the length of the display panel. The protective film 22 is peeled off from the extended edge portion.
2. 帶電電壓測定裝置之電氣構成 圖3係表示帶電電壓測定裝置1之電氣構成之一例的方塊圖。藉由使例如包含CPU(Central Processing Unit：中央處理單元)之控制部10執行程序，從而控制該帶電電壓測定裝置1之動作。控制部10除了與上述剝離機構12及測定器13電連接以外，還與顯示部14等電連接。2. Electrical configuration of the charged voltage measuring device Fig. 3 is a block diagram showing an example of the electrical configuration of the charged voltage measuring device 1. The control unit 10 including, for example, a CPU (Central Processing Unit) executes a program to control the operation of the charged voltage measurement device 1. The control unit 10 is electrically connected to the display unit 14 and the like in addition to the above-mentioned peeling mechanism 12 and the measuring device 13.
剝離機構12具有剝離用馬達124。剝離用馬達124經由齒輪(未圖示)等機械性連接於捲取輥123。藉由驅動該剝離用馬達124，從而使捲取輥123旋轉，能夠一邊使保護薄膜22自顯示面板2之表面21剝離一邊將保護薄膜22捲取於捲取輥123。捲取輥123之轉速既可以為預先設定好的一定速度，亦能夠由使用者設定為任意速度。The peeling mechanism 12 includes a peeling motor 124. The peeling motor 124 is mechanically connected to the take-up roller 123 via a gear (not shown) or the like. By driving the peeling motor 124 to rotate the take-up roller 123, the protective film 22 can be taken up by the take-up roller 123 while the protective film 22 is peeled from the surface 21 of the display panel 2. The rotation speed of the take-up roller 123 may be a predetermined speed set in advance, or may be set to an arbitrary speed by a user.
本實施形態中，剝離機構12具有用於使保持部11沿移動方向D1移動之移動機構120。移動機構120具有經由齒輪(未圖示)等而機械性連接於保持部11之移動用馬達125。藉由驅動該移動用馬達125，能夠使保持部11以經設定之移動速度沿移動方向D1移動。上述移動速度既可以為預先設定之一定速度，亦能夠由使用者設定為任意速度。In this embodiment, the peeling mechanism 12 includes a moving mechanism 120 for moving the holding portion 11 in the moving direction D1. The moving mechanism 120 includes a moving motor 125 that is mechanically connected to the holding portion 11 via a gear (not shown) or the like. By driving the moving motor 125, the holding portion 11 can be moved in the moving direction D1 at a set moving speed. The above-mentioned moving speed may be a certain speed set in advance, or may be set to an arbitrary speed by a user.
移動用馬達125與剝離用馬達124同步地驅動。即，以與利用剝離用馬達124捲取保護薄膜22的速度相同的速度，利用移動用馬達125使保持部11沿移動方向D1移動。然而，亦可為藉由1個馬達之驅動而同步進行捲取輥123之旋轉及保持部11之移動的構成。The moving motor 125 is driven in synchronization with the peeling motor 124. That is, the holding portion 11 is moved in the moving direction D1 by the moving motor 125 at the same speed as the speed at which the protective film 22 is taken up by the peeling motor 124. However, a configuration in which the rotation of the take-up roller 123 and the movement of the holding portion 11 are synchronized by the driving of one motor may be adopted.
顯示部14例如由液晶顯示器構成。顯示部14顯示由測定器13測得之顯示面板2之表面21的電壓值等之測定結果。使用者藉由確認顯示之顯示部14之測定結果，能夠評價測定對象物即顯示面板2能否使用。根據該評價，例如，亦可採取增加保護薄膜22之黏著劑中含有之抗靜電劑的量等改善措施。然而，顯示部14並不限於與測定器13分離地設置的構成，例如亦可為與測定器13一體地設置的構成等。The display unit 14 is configured by, for example, a liquid crystal display. The display unit 14 displays measurement results such as the voltage value of the surface 21 of the display panel 2 measured by the measuring device 13. By confirming the measurement result of the display unit 14 displayed on the display, the user can evaluate whether or not the display panel 2 which is a measurement object can be used. Based on this evaluation, for example, improvement measures such as increasing the amount of the antistatic agent contained in the adhesive of the protective film 22 may be adopted. However, the display unit 14 is not limited to a configuration provided separately from the measurement device 13, and may be a configuration provided integrally with the measurement device 13, for example.
如此，本實施形態中，能夠使用移動機構120使保持部11以經設定之移動速度精度良好地移動。因而，測定結果不易產生偏差，能夠進一步精度良好地測定顯示面板2之表面21的帶電電壓。As described above, in the present embodiment, the moving unit 120 can be used to move the holding portion 11 with high accuracy at a set moving speed. Therefore, the measurement results are less likely to vary, and the charged voltage on the surface 21 of the display panel 2 can be further accurately measured.
使保護薄膜22自顯示面板2之表面21剝離時之保持部11之移動速度例如為10～100 m/min。藉此，能夠一邊使保持部11以適當之移動速度移動，一邊使保護薄膜22自顯示面板2之表面21剝離，因此，測定結果不易產生偏差，能夠進一步精度良好地測定顯示面板2之表面21的帶電電壓。The moving speed of the holding portion 11 when the protective film 22 is peeled from the surface 21 of the display panel 2 is, for example, 10 to 100 m / min. Thereby, the protective film 22 can be peeled from the surface 21 of the display panel 2 while the holding portion 11 is moved at an appropriate moving speed. Therefore, the measurement results are less likely to vary, and the surface 21 of the display panel 2 can be further accurately measured. Live voltage.
3. 帶電電壓測定裝置之變化例 圖4係局部地顯示帶電電壓測定裝置1之變化例的概略側視圖。於該示例中，非藉由移動機構120使保持部11移動，而是利用剝離保護薄膜22時作用於顯示面板2之力來使保持部11移動，此點與上述實施形態不同。3. Modified Example of the Charged Voltage Measuring Device FIG. 4 is a schematic side view partially showing a modified example of the charged voltage measuring device 1. In this example, instead of moving the holding portion 11 by the moving mechanism 120, the holding portion 11 is moved by the force acting on the display panel 2 when the protective film 22 is peeled off, which is different from the above embodiment.
具體而言，保持部11沿著上述移動方向D1移動自如。即，設於保持部11之複數個輥112旋轉自如，於有外力作用於保持部11之情形時，保持部11能夠沿著移動方向D1自由地移動。Specifically, the holding portion 11 can move freely in the moving direction D1. That is, the plurality of rollers 112 provided in the holding portion 11 can rotate freely, and when an external force acts on the holding portion 11, the holding portion 11 can move freely in the moving direction D1.
再者，於剝離位置P附近固定有剝離構件24。自顯示面板2之表面21剝離的保護薄膜22其表面滑動接觸於剝離構件24，而自移動方向D1朝剝離方向D2轉向並受引導。惟剝離構件24並不限於被固定的構成，例如亦可由能夠利用來自要剝離之保護薄膜22所作用之力進行旋轉的輥等構成。Further, a peeling member 24 is fixed near the peeling position P. The surface of the protective film 22 peeled from the surface 21 of the display panel 2 slides into contact with the peeling member 24, and turns from the moving direction D1 toward the peeling direction D2 and is guided. However, the peeling member 24 is not limited to a fixed structure. For example, the peeling member 24 may be a roller or the like that can be rotated by a force applied from the protective film 22 to be peeled.
該情形時，當使保護薄膜22自顯示面板2之表面21剝離時，力沿圖4中箭頭D2所示之剝離方向作用於保護薄膜22。於連續地剝離保護薄膜22之情形時，利用保護薄膜22之黏著劑與顯示面板2之表面21之間產生的黏著力，將顯示面板2沿移動方向D1牽引，而對顯示面板2沿圖4中箭頭D3所示之方向作用力。利用剝離該保護薄膜22時作用於顯示面板2之力，能使保持部11沿移動方向D1移動。In this case, when the protective film 22 is peeled from the surface 21 of the display panel 2, a force acts on the protective film 22 in a peeling direction shown by an arrow D2 in FIG. 4. When the protective film 22 is continuously peeled off, the display panel 2 is pulled in the moving direction D1 by using the adhesive force generated between the adhesive of the protective film 22 and the surface 21 of the display panel 2, and the display panel 2 is pulled along FIG. 4. The force acts in the direction shown by the middle arrow D3. The force applied to the display panel 2 when the protective film 22 is peeled off can move the holding portion 11 in the moving direction D1.
該例中，藉由自顯示面板2之表面21使保護薄膜22連續地剝離，利用剝離保護薄膜22時作用於顯示面板2之力，能使保持部11穩定地移動。因而，即使為不具備移動機構120之簡單的構成，測定結果亦不易產生偏差，能夠精度良好地測定顯示面板2之表面21的帶電電壓。In this example, the protective film 22 is continuously peeled from the surface 21 of the display panel 2, and the holding portion 11 can be stably moved by the force acting on the display panel 2 when the protective film 22 is peeled off. Therefore, even with a simple configuration that does not include the moving mechanism 120, the measurement results are less likely to vary, and the charged voltage on the surface 21 of the display panel 2 can be accurately measured.
4. 其他變化例 用於使保護薄膜22自顯示面板2之表面21剝離的剝離機構12並不限於將保護薄膜22捲取於捲取輥123之構成，亦可為僅藉由牽引保護薄膜22而使其剝離之構成等。4. Other Variations The peeling mechanism 12 for peeling the protective film 22 from the surface 21 of the display panel 2 is not limited to a configuration in which the protective film 22 is wound on a take-up roller 123, and the protective film 22 may be pulled only by pulling. The structure of peeling it off.
於以上之實施形態中，說明了顯示面板2為液晶面板之情況。然而，本發明並不限於液晶面板，亦可應用於有機EL(Electro Luminescence)面板等其他顯示面板。In the above embodiment, the case where the display panel 2 is a liquid crystal panel has been described. However, the present invention is not limited to a liquid crystal panel, and can also be applied to other display panels such as an organic EL (Electro Luminescence) panel.
另外，於以上之實施形態中，說明了如使用帶電電壓測定裝置1來自動地測定顯示面板2之表面21的帶電電壓般之構成。然而，並不限於此種構成，亦可為，藉由用戶進行操作，從而手動地進行剝離步驟及測定步驟中之至少一者。In addition, in the above embodiment, the configuration is described in which the charged voltage on the surface 21 of the display panel 2 is automatically measured using the charged voltage measuring device 1. However, it is not limited to such a configuration, and at least one of a peeling step and a measuring step may be performed manually by a user.
5. 帶電電壓測定之實驗結果 以下，說明使用帶電電壓測定裝置以複數個測定條件來測定顯示面板之表面之帶電電壓之結果。測定中使用之顯示面板2之尺寸為JIS(日本工業標準)中之A4尺寸。本發明之帶電電壓測定裝置還能夠使用於A4尺寸以外的顯示面板，但尺寸越大的顯示面板越容易產生因帶電電壓導致的顯示面板之故障等，因此，本發明使用於A4尺寸以上的顯示面板之價值較高。5. Experimental results of charged voltage measurement The results of measuring the charged voltage on the surface of the display panel using the charged voltage measuring device under a plurality of measurement conditions are described below. The size of the display panel 2 used in the measurement was A4 size in JIS (Japanese Industrial Standard). The charged voltage measuring device of the present invention can also be used for display panels other than A4 size. However, the larger the size of the display panel, the more easily the display panel may fail due to the charged voltage. Therefore, the present invention is used for displays larger than A4 The value of the panel is high.
於以各測定條件進行測定時，自同一批捲狀物隨機地切出各100張保護薄膜，將其貼合於顯示面板，藉此製作100個測定對象物。隨後，將該等測定對象物依次置於帶電電壓測定裝置，藉由在各顯示面板之中央部著急哦1點測定帶電電壓，從而基於該測定結果計算出標準偏差。其結果表示於以下之表1中。 [表1]
(1)實施例1 藉由不使測定器移動而使顯示面板沿移動方向D1移動，從而一邊以30 m/min之剝離速度剝離保護薄膜，一邊於與顯示面板之表面隔開30 mm之間隔的位置利用測定器測定帶電電壓，所測定到之結果為上述表1中之實施例1對應之結果。按照該測定結果，可知，於實施例1中，標準偏差為0.013這樣比較小的值(小於0.05)，能夠精度良好地測定帶電電壓。(1) Example 1 By moving the display panel in the moving direction D1 without moving the measuring device, the protective film was peeled at a peeling speed of 30 m / min while being separated by a distance of 30 mm from the surface of the display panel.

The charged voltage was measured by a measuring device at the position of. The measured result is the result corresponding to Example 2 in Table 1 above. From this measurement result, it can be seen that in Example 2, the standard deviation is a relatively small value (less than 0.05) such as 0.020, and the charged voltage can be measured with high accuracy.
(3)實施例3 藉由不使測定器移動而使顯示面板沿移動方向D1移動，從而一邊以100 m/min之剝離速度剝離保護薄膜，一邊於與顯示面板之表面隔開30 mm之間隔的位置利用測定器來測定帶電電壓，所測定到之結果為上述表1中的實施例3對應之結果。按照該測定結果，可知，於實施例3中，標準偏差為0.031這樣比較小的值(小於0.05)，能夠精度良好地測定帶電電壓。(3) Example 3 By moving the display panel in the moving direction D1 without moving the measuring device, the protective film was peeled at a peeling speed of 100 m / min while being separated from the surface of the display panel by a distance of 30 mm. The charged voltage was measured with a measuring device at the position of. The measured result is the result corresponding to Example 3 in Table 1 above. From this measurement result, it is understood that in Example 3, the standard deviation is a relatively small value (less than 0.05) such as 0.031, and the charged voltage can be measured with high accuracy.
(4)實施例4 藉由不使測定器移動而使顯示面板沿移動方向D1移動，從而一邊以30 m/min之剝離速度剝離保護薄膜，一邊於與顯示面板之表面隔開5 mm之間隔的位置利用測定器來測定帶電電壓，所測定到之結果為上述表1中的實施例4對應之結果。按照該測定結果，可知，於實施例4中，標準偏差為0.031這樣比較小的值(小於0.05)，能夠精度良好地測定帶電電壓。(4) Example 4 By moving the display panel in the moving direction D1 without moving the measuring device, the protective film was peeled at a peeling speed of 30 m / min while being separated by a distance of 5 mm from the surface of the display panel. The measurement of the charged voltage is performed by a measuring device at the position of. The measured result is the result corresponding to Example 4 in Table 1 above. From this measurement result, it is understood that in Example 4, the standard deviation is a relatively small value (less than 0.05) such as 0.031, and the charged voltage can be measured with high accuracy.
(5)實施例5 藉由不使測定器移動而使顯示面板沿移動方向D1移動，從而一邊以30 m/min之剝離速度剝離保護薄膜，一邊於與顯示面板之表面隔開50 mm之間隔的位置利用測定器來測定帶電電壓，所測定到之結果為上述表1中的實施例5對應之結果。按照該測定結果，可知，於實施例5中，標準偏差為0.011這樣比較小的值(小於0.05)，能夠精度良好地測定帶電電壓。(5) Example 5 By moving the display panel in the moving direction D1 without moving the measuring device, the protective film was peeled at a peeling speed of 30 m / min while being separated by a distance of 50 mm from the surface of the display panel. The measurement of the charged voltage is performed by a measuring device at the position of the sensor. The measured result is the result corresponding to Example 5 in Table 1 above. From this measurement result, it is understood that in Example 5, the standard deviation is a relatively small value (less than 0.05) such as 0.011, and the charged voltage can be measured with high accuracy.
(6)比較例1 藉由不使測定器移動而使顯示面板沿移動方向D1移動，從而一邊以30 m/min之剝離速度剝離保護薄膜，一邊於與顯示面板之背面隔開30 mm之間隔的位置利用測定器來測定帶電電壓，所測定到之結果為上述表1中之比較例1對應之結果。具體而言，使用治具將測定器安裝於保持部的背面，並於保持部的與測定點(顯示面板之中央部之1點)相對應的位置設置通孔，藉此測定顯示面板之背面的帶電電壓。按照該測定結果，可知，於比較例1中，標準偏差為0.032這樣比較小的值(小於0.05)。(6) Comparative Example 1 By moving the display panel in the moving direction D1 without moving the measuring device, the protective film was peeled at a peeling speed of 30 m / min while being separated by a distance of 30 mm from the back of the display panel. The measurement of the charged voltage was performed by a measuring device at the position of. The measured result is the result corresponding to Comparative Example 1 in Table 1 above. Specifically, a measuring instrument is mounted on the back surface of the holding portion using a jig, and a through hole is provided at a position corresponding to the measurement point (1 point in the center portion of the display panel) of the holding portion to measure the rear surface of the display panel. Live voltage. From this measurement result, it is understood that in Comparative Example 1, the standard deviation is a relatively small value (less than 0.05) such as 0.032.
於比較例1中，不僅針對顯示面板之背面利用測定器測定帶電電壓，還同時於與表面隔開30 mm間隔的位置利用測定器測定帶電電壓，並計算出標準偏差。此時的標準偏差為0.069這樣比較大的值(0.05以上)。如此，由於在測定顯示面板之背面之帶電電壓時及測定表面之帶電電壓時標準偏差存在較大的偏差，因此可知，與實施例1～實施例5的情況相比，於比較例1中，帶電電壓之測定精度較低。In Comparative Example 1, not only the charging voltage was measured with a measuring device for the back surface of the display panel, but also the measuring voltage was measured with a measuring device at a distance of 30 mm from the surface, and the standard deviation was calculated. The standard deviation at this time is a relatively large value (0.05 or more) such as 0.069. In this way, since the standard deviation is large when measuring the charged voltage on the back surface of the display panel and when measuring the charged voltage on the surface, it can be seen that compared with the cases of Examples 1 to 5, in Comparative Example 1, The measurement accuracy of the charged voltage is low.
(7)比較例2 一邊不使顯示面板移動而以30 m/min之剝離速度剝離保護薄膜，一邊使測定器沿與移動方向D1相反的方向移動，於與顯示面板之表面隔開30 mm之間隔的位置利用測定器測定帶電電壓，所測定到之結果為上述表1中之比較例2對應之結果。按照該測定結果，可知，於比較例2中，標準偏差為0.19這樣比較大的值(0.05以上)，與實施例1～實施例5的情況相比，帶電電壓之測定精度較低。(7) Comparative Example 2 While the protective film was peeled at a peeling speed of 30 m / min without moving the display panel, the measuring device was moved in a direction opposite to the moving direction D1 and separated from the surface of the display panel by 30 mm. The position of the interval was measured by the measuring device with the charging voltage. The measured result was the result corresponding to Comparative Example 2 in Table 1 above. Based on the measurement results, it can be seen that, in Comparative Example 2, the standard deviation is a relatively large value (0.05 or more) such as 0.19, and the measurement accuracy of the charged voltage is lower than that in Examples 1 to 5.
(8)參考例1 藉由不使測定器移動而使顯示面板沿移動方向D1移動，從而一邊以30 m/min之剝離速度剝離保護薄膜，一邊於與顯示面板之表面隔開3 mm之間隔的位置利用測定器來測定帶電電壓，所測定到之結果為上述表1中之參考例1對應之結果。按照該測定結果，可知，於參考例1中，標準偏差為0.12這樣比較大的值(0.05以上)，與實施例1～實施例5的情況相比，帶電電壓之測定精度較低。(8) Reference example 1 By moving the display panel in the moving direction D1 without moving the measuring device, the protective film was peeled at a peeling speed of 30 m / min while being separated by a distance of 3 mm from the surface of the display panel. The position is measured by a measuring device, and the measured result is the result corresponding to Reference Example 1 in Table 1 above. According to the measurement results, it can be seen that in Reference Example 1, the standard deviation is a relatively large value (0.05 or more) such as 0.12, and the measurement accuracy of the charged voltage is lower than that in Examples 1 to 5.
由以上所述之實驗結果可知，使保護薄膜自顯示面板剝離時之剝離速度(保持部之移動速度)較佳為10 m/min～100 m/min。另外，可知，較佳為，測定器以與顯示面板之表面對向之方式配置，且該測定器與顯示面板之表面之間的間隔為5 mm～50 mm。From the experimental results described above, it is known that the peeling speed (moving speed of the holding portion) when the protective film is peeled from the display panel is preferably 10 m / min to 100 m / min. In addition, it can be seen that the measuring device is preferably arranged to face the surface of the display panel, and the interval between the measuring device and the surface of the display panel is preferably 5 mm to 50 mm.
