[0041] Example 1

[0042] Figure 1 This is a schematic diagram of the auxiliary tooling structure for TFT compressive strength testing according to an embodiment of this application. Figure 2 This is a side view of the TFT compressive strength testing auxiliary tooling according to an embodiment of this application. The following will be combined with... Figure 1-2The auxiliary tooling for testing the compressive strength of TFTs according to embodiments of this application will be described in detail.

[0043] In one exemplary embodiment, the TFT compressive strength testing auxiliary tooling of this application embodiment is used to assist in testing the compressive strength of TFTs.

[0044] In one exemplary embodiment, the TFT compressive strength testing auxiliary tooling of this application includes: a first support 101 and a second support 102.

[0045] In one exemplary embodiment, the second support 102 is movably disposed on the first support 101. For example, the second support 102 can slide on the first support 101 as needed; its sliding can be, for example, sliding in the vertical direction or sliding in the horizontal direction. Figure 1 As shown.

[0046] In one exemplary embodiment, a plurality of adsorption components 103 are movably provided on the second support 102.

[0047] In one exemplary embodiment, there are multiple second supports 102 and adsorption components 103.

[0048] In one exemplary embodiment, the adsorption component 103 is used to adsorb onto the TFT.

[0049] In one exemplary embodiment, the adsorption assembly 103 includes: an air tube 1031, a regulating valve 1034, and a suction cup 1032.

[0050] In one exemplary embodiment, the suction cup 1032 is mounted at the end of the air tube 1031, for example, the suction cup 1032 is mounted at the lower end of the air tube 1031, such as... Figure 2 As shown.

[0051] In one exemplary embodiment, a regulating valve 1034 is disposed on an air pipe 1031.

[0052] In one exemplary embodiment, the regulating valve 1034 is used to regulate the suction force of the suction cup 1032 on the TFT. This can be understood as regulating the diameter of the air pipe 1031 by regulating the regulating valve 1034, thereby adjusting the suction force of the suction cup 1032 on the TFT.

[0053] In one exemplary embodiment, the trachea 1031 is fixed to the second bracket 102 by a fixing component 1033. It can be understood that when it is necessary to fix the trachea 1031 to a certain position of the second bracket 102, the trachea 1031 is fixed to the second bracket 102 by the fixing component 1033.

[0054] In one exemplary embodiment, when the first support 101 is connected to the second support 102, the adsorption component 103 is disposed on the same side of the first support 101.

[0055] In one exemplary embodiment, when there are two first supports 101, the adsorption assembly 103 on the second support 102 is surrounded by the first supports 101 on both sides, such as... Figure 1 As shown.

[0056] In one exemplary embodiment, the second support 102 is movably disposed between the two first supports 101.

[0057] In one exemplary embodiment, the number of adsorption components 103 on the plurality of second supports 102 is the same.

[0058] In one exemplary embodiment, the end of the trachea 1031 furthest from the suction cup 1032 is provided with a connector 1035, that is, the connector 1035 is located at the upper end of the trachea 1031, such as... Figure 2 As shown.

[0059] In one exemplary embodiment, the TFT pressure resistance testing auxiliary tooling of this application embodiment further includes: an air intake unit.

[0060] In one exemplary embodiment, the intake unit is connected to connector 1035.

[0061] In one exemplary embodiment, the suction unit is used to provide suction to the suction cup 1032; it can be understood that the suction unit is connected to the connector 1035 to draw suction from the air tube 1031, and then the suction cup 1032 at the lower end of the air tube 1031 generates an adsorption force on the TFT.

[0062] In one exemplary embodiment, the suction force of one or more adsorption components 103 on the TFT can be adjusted by adjusting the suction force. Since the suction cup 1032 is plastic and deformable, when the suction force is increased, the TFT at the corresponding position of the suction cup 1032 will have a slight upward movement. The presence of light leakage at that position can be observed.

[0063] In one exemplary embodiment, each second support 102 has at least three adsorption components 103.

[0064] In one exemplary embodiment, there are no fewer than three second supports 102.

[0065] Although the embodiments disclosed in this utility model are as described above, the content is only for the purpose of facilitating understanding of this utility model and is not intended to limit this utility model. Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
