Description
本發明係有關一種檢測方法與檢測設備，尤指一種檢測面板框膠強度的檢測方法與檢測設備。The invention relates to a detection method and a detection device, in particular to a detection method and a detection device for detecting the frame glue strength of a panel.
傳統的面板單元(cell)的框膠強度的測試方式是在面板單元的兩片基板(彩色濾光片玻璃基板以及薄膜電晶體陣列玻璃基板)的兩側分別黏上拉力機構的測頭，其中一側的測頭固定不動，另一側的測頭則以固定速度向外拉動直到基板分開(peeling)時，記錄拉力機構所讀取的數值即為面板框膠的強度。The test method of the frame strength of a conventional panel unit is to apply a probe of a tension mechanism on both sides of a two-piece substrate (a color filter glass substrate and a thin film transistor array glass substrate) of the panel unit, wherein The probe on one side is fixed, and the probe on the other side is pulled outward at a fixed speed until the substrate is peeled. The value read by the tension mechanism is the strength of the panel seal.
進行框膠強度測試前，於拉力機構的測頭固定程序中，首先需將面板單元的上下偏光板移除，並以酒精擦拭基板中欲測試的位置以及拉力機構的測頭部分。接著在測頭上以人工塗上瞬間膠後，將一測頭黏於彩色濾光片玻璃基板上，另一測頭黏於薄膜電晶體陣列玻璃基板上，並輕壓一定時間。這樣的測試方式要求兩測頭的中心應在同一中心軸上，然而這種以人工黏合的方式，往往無法確保基板兩側的測頭準確位於同一中心軸上。請參考第1圖，第1圖即為先前技術的拉力機構的測頭固定於面板單元的基板上的示意圖。在第1圖中，拉力機構的一測頭32黏合於第一基板10上，另一測頭34黏合於第二基板20上，雖然在黏合拉力機構的測頭32、34時，需注意讓兩測頭32、34的中心盡量在同一中心軸上，但如第1圖的配置1所示，由於人工黏合所產生的誤差，往往使測頭32的軸線A1 與測頭34的軸線A2 無法位於同一中心軸上。另一方面，測頭32、34與基板10、20之間的瞬間膠用量以及均勻度也無法獲得有效的標準化控制，點膠的不均勻也會造成拉力機構的測頭32、34歪斜，無法以垂直於基板10、20的方向黏合，如第1圖的配置2中，測頭32以及測頭34的軸線A3 、A4 即因點膠不均勻而彼此歪斜，無法位於同一中心軸上。Before performing the frame glue strength test, in the probe fixing procedure of the tension mechanism, firstly, the upper and lower polarizing plates of the panel unit are removed, and the position to be tested in the substrate and the probe portion of the tension mechanism are wiped with alcohol. Then, after manually applying the instant glue on the probe, a probe is adhered to the color filter glass substrate, and the other probe is adhered to the thin film transistor array glass substrate and pressed for a certain time. Such a test method requires that the centers of the two probes should be on the same central axis. However, in the case of manual bonding, it is often impossible to ensure that the probes on both sides of the substrate are exactly on the same central axis. Please refer to FIG. 1 , which is a schematic diagram of the probe of the prior art tension mechanism fixed on the substrate of the panel unit. In the first figure, a probe 32 of the tension mechanism is bonded to the first substrate 10, and the other probe 34 is bonded to the second substrate 20. Although the probes 32 and 34 of the tension mechanism are bonded, care must be taken. The centers of the two probes 32, 34 are as close as possible to the same central axis, but as shown in the configuration 1 of Fig. 1, the axis A 1 of the probe 32 and the axis A of the probe 34 are often caused by errors caused by manual bonding. 2 cannot be on the same center axis. On the other hand, the instantaneous amount of glue and the uniformity between the probes 32, 34 and the substrates 10, 20 cannot be effectively standardized. The unevenness of the dispensing may also cause the probes 32, 34 of the tension mechanism to be skewed. Bonding in a direction perpendicular to the substrates 10, 20, as in the arrangement 2 of Fig. 1, the axes A 3 and A 4 of the probe 32 and the probe 34 are skewed from each other due to uneven dispensing, and cannot be located on the same central axis. .
此外，這種在測頭與基板之間以瞬間膠黏合的方式，為確保拉力機構的測頭能牢固黏合在基板上，當黏合時需要以人工施加特定的力量一段時間，且接著需等候測頭上的瞬間膠風乾一小時以上，使測頭與基板之間黏合效果更佳才能進行框膠強度的測試。以上的問題均會影響基板之間的框膠強度的量測結果，同時增加測試所需的時間。In addition, in the manner of instant adhesive bonding between the probe and the substrate, in order to ensure that the probe of the tension mechanism can be firmly adhered to the substrate, it is necessary to manually apply a specific force for a certain period of time when bonding, and then wait for the test. The instant glue on the head is dried for more than one hour, so that the bonding effect between the probe and the substrate is better to test the seal strength. All of the above problems will affect the measurement results of the sealant strength between the substrates, and increase the time required for the test.

請參考第2圖，第2圖為面板單元100的第一基板40以及第二基板50以框膠60黏合後的示意圖。第一基板40較佳地為彩色濾光層(color filter,CF)基材，第二基板50較佳地為薄膜電晶體陣列(thin film transistor,TFT)基材，在第一基板40的一第一側41以及第二基板50的一第二側52的相對應四周之間塗佈框膠60，使第一基板40的第一側41以及第二基板50的第二側52沿著F1 F2 方向彼此接合以形成面板單元100。第一基板40相對第一側41具有一第三側43，在第二基板50的第二側52上則具有一露出面55。當第一基板40與第二基板50接合時，第一基板40不會覆蓋於露出面55上。Please refer to FIG. 2 . FIG. 2 is a schematic view showing the first substrate 40 and the second substrate 50 of the panel unit 100 bonded by the sealant 60 . The first substrate 40 is preferably a color filter (CF) substrate, and the second substrate 50 is preferably a thin film transistor (TFT) substrate, one of the first substrate 40 The sealant 60 is applied between the first side 41 and the corresponding circumference of a second side 52 of the second substrate 50 such that the first side 41 of the first substrate 40 and the second side 52 of the second substrate 50 follow the F The 1 F 2 directions are joined to each other to form the panel unit 100. The first substrate 40 has a third side 43 opposite the first side 41 and an exposed side 55 on the second side 52 of the second substrate 50. When the first substrate 40 is bonded to the second substrate 50, the first substrate 40 does not cover the exposed surface 55.
請參考第3圖以及第4圖，其中第3圖為本發明所揭露的一檢測設備200作用於面板單元100的側視示意圖，第4圖則為第3圖中沿著一第二方向F2 面對第一基板40的第三側43以及第二基板50的露出面55的正視示意圖。在本發明的實施例中，檢測設備200包含有一吸引裝置70以及一推力機構80，吸引裝置70較佳地為利用真空產生吸力的真空吸引裝置，其可以真空轉換器將壓縮空氣系統中的CDA(clean/compressed dry air)轉換成真空，以吸住面板單元100的基板。如第3圖以及第4圖所示，吸引裝置70可具有一吸盤72，針對如第2圖所示的面板單元100，吸盤72在一第一軸線A5 上，沿著圖中的第一方向F1 吸住第一基板40的第三側43以固定第一基板40。從第4圖的正視示意圖可看到，吸引裝置70的吸盤72較佳地設置在第一基板40的第三側43鄰近於第二基板50的露出面55的兩個端角46、47其中一端角，例如在第4圖的實施例中，吸盤72設置在端角46上，且吸盤72的邊緣與第一基板40形成端角46的相鄰兩側邊44、45實質上切齊。由於實務上，圓形吸盤72可容易切齊第一基板40的相鄰側邊44、45，如此一來，吸引裝置70的吸盤72可快速且有效地設置在第一基板40的塗佈框膠的邊緣，而其以形成真空吸力的方式固定第一基板40亦可達到以相當短的時間即可有效固定的作用。Please refer to FIG. 3 and FIG. 4 , wherein FIG. 3 is a side view of a detecting device 200 for the panel unit 100 according to the present invention, and FIG. 4 is a second direction F of FIG. 3 . 2 is a front view showing the third side 43 of the first substrate 40 and the exposed surface 55 of the second substrate 50. In an embodiment of the invention, the detecting device 200 includes a suction device 70 and a thrust mechanism 80, which is preferably a vacuum suction device that utilizes vacuum to generate suction, which can vacuum the CDA in the compressed air system. (clean/compressed dry air) is converted into a vacuum to suck the substrate of the panel unit 100. As shown in Figures 3 and 4, the suction device 70 can have a suction cup 72. For the panel unit 100 as shown in Fig. 2, the suction cup 72 is on a first axis A 5 along the first line in the figure. The direction F 1 attracts the third side 43 of the first substrate 40 to fix the first substrate 40. As can be seen from the front view of Fig. 4, the suction cup 72 of the suction device 70 is preferably disposed at the two end angles 46, 47 of the third side 43 of the first substrate 40 adjacent to the exposed face 55 of the second substrate 50. At one end angle, for example, in the embodiment of Fig. 4, the suction cup 72 is disposed at the end angle 46, and the edge of the suction cup 72 is substantially aligned with the adjacent side edges 44, 45 of the first substrate 40 forming the end angle 46. In practice, the circular suction cup 72 can easily align the adjacent sides 44, 45 of the first substrate 40, so that the suction cup 72 of the suction device 70 can be quickly and efficiently disposed on the coating frame of the first substrate 40. The edge of the glue, which is fixed to the first substrate 40 in a vacuum suction manner, can also be effectively fixed in a relatively short period of time.
當吸引裝置70固定第一基板40後，接著利用檢測設備200中的推力機構80，以人工或設備自動化的方式，在一第二軸線A6 上，沿著第3圖中的第一方向F1 之相反方向(即第二方向F2 )推抵第二基板50的第二側52。更具體而言，推力機構80推抵第二側52上的露出面55。隨著推力機構80沿著第二方向F2 的推抵力量增加(同時吸引裝置70沿著第一方向F1 吸引固定第一基板40)，第一基板40以及第二基板50之間的框膠60承受逐漸增大的外在應力，直到超過框膠黏合兩基板40、50的臨界強度時，第二基板50自第一基板40剝離(如第3圖中的虛線所示)，此時推力機構80所測得的力量數值即可代表面板框膠的強度。When the suction device 70 is fixed a first substrate 40, and then using the detection apparatus 200 in the thrust mechanism 80, the device manually or automated manner, on a second axis A 6, along the first direction F in FIG. 3 The opposite direction of 1 (i.e., the second direction F 2 ) is pushed against the second side 52 of the second substrate 50. More specifically, the thrust mechanism 80 pushes against the exposed face 55 on the second side 52. As the pushing force of the thrust mechanism 80 along the second direction F 2 increases (while the attraction device 70 attracts and fixes the first substrate 40 along the first direction F 1 ), the frame between the first substrate 40 and the second substrate 50 The adhesive 60 is subjected to a gradually increasing external stress until the critical strength of the two substrates 40, 50 is adhered, and the second substrate 50 is peeled off from the first substrate 40 (as indicated by a broken line in FIG. 3). The force value measured by the thrust mechanism 80 can represent the strength of the panel seal.
特別說明的是，本發明的檢測設備200中的吸引裝置70設置在第一基板40靠近露出面55的端角46上，而推力機構80在面板單元100的同一邊推抵第二基板50的露出面55。由圖可看出，吸引裝置70與推力機構80分別設置在兩個相異的第一軸線A5 以及第二軸線A6 上，且沿著相反的方向分別對兩基板40、50作用，在推力機構80對第二基板50施力以獲得框膠的臨界強度過程中，由於相異軸施力導致框膠受到明顯力矩，故對框膠臨界強度的檢測更加敏感，因此可有效針對框膠強度進行測試。Specifically, the suction device 70 in the detecting device 200 of the present invention is disposed on the end angle 46 of the first substrate 40 near the exposed surface 55, and the thrust mechanism 80 is pushed against the second substrate 50 on the same side of the panel unit 100. The face 55 is exposed. As can be seen from the figure, the suction device 70 and the thrust mechanism 80 are respectively disposed on the two different first axis A 5 and the second axis A 6 , and respectively act on the opposite substrates 40 and 50 in opposite directions. When the thrust mechanism 80 applies the force to the second substrate 50 to obtain the critical strength of the sealant, the frame glue is subjected to the obvious moment due to the different axial force, so the detection of the critical strength of the sealant is more sensitive, so the frame glue can be effectively targeted. Strength is tested.
請參考第5圖，第5圖即為使用本發明所揭露的檢測設備以檢測面板的框膠強度的檢測方法300流程示意圖，其步驟如下：步驟302：利用吸引裝置70沿著第一方向F1 吸引第一基板40的第三側43以固定第一基板40；步驟304：利用推力機構80沿著第二方向F2 推抵第二基板50的第二側52；步驟306：當第二基板50自第一基板40剝離時，記錄推力機構80的一力量數值。Please refer to FIG. 5 , which is a schematic flowchart of a method 300 for detecting the strength of the sealant of the panel by using the detecting device disclosed in the present invention. The steps are as follows: Step 302: using the suction device 70 along the first direction F 1 attracting the third side 43 of the first substrate 40 to fix the first substrate 40; Step 304: pushing the second side 52 of the second substrate 50 along the second direction F 2 by the thrust mechanism 80; Step 306: When the second When the substrate 50 is peeled off from the first substrate 40, a force value of the thrust mechanism 80 is recorded.
其中在步驟302，如前所述，吸引裝置70係於第一軸線A5 上可以吸盤72吸引第一基板40的端角46，吸盤72實質上與形成端角46的兩相鄰側邊44、45切齊。而步驟304中的推力機構80係推抵第二基板50的第二側52上的露出面55。In step 302, as described above, the suction device 70 is attached to the first axis A 5 so that the suction cup 72 can attract the end angle 46 of the first substrate 40. The suction cup 72 substantially forms two adjacent sides 44 of the end angle 46. 45 cut. The thrust mechanism 80 in step 304 is pushed against the exposed surface 55 on the second side 52 of the second substrate 50.
本發明所揭露的面板框膠檢測設備以及檢測方法，可利用一吸引裝置以真空吸盤在第一軸線上沿著第一方向吸引固定面板單元的第一基板的第三側的端角。利用一推力機構以人工或設備自動化的方式，在第二軸線上沿著第一方向的相反方向推抵第二基板的第二側上的露出面。當第二基板自第一基板剝離時，再記錄推力機構所產生的力量數值，如此可以簡易且精確的方式測得面板框膠的強度。The panel sealant detecting device and the detecting method disclosed in the present invention can utilize a suction device to attract the end angle of the third side of the first substrate of the fixed panel unit in the first direction by the vacuum chuck on the first axis. The exposed surface on the second side of the second substrate is urged in the opposite direction of the first direction on the second axis by a thrust mechanism in a manual or device automated manner. When the second substrate is peeled off from the first substrate, the value of the force generated by the thrust mechanism is recorded, so that the strength of the panel seal can be measured in a simple and accurate manner.
