With having a movable test hole equipped in the present invention, an adjustable test of the local antistress test platform can be achieved. During use, the test frame 300 is located above the tested panel. The movable test hole table 302 can be located above the antistress test position of the tested panel without the test frame 300 to achieve the precise location for the antistress test position of the tested panel because the movable test hole table 302 and the test frame 300 are removably jointed with each other. Then, the weight test rod 301 is employed for adding weights or other heavy stuff to proceed the local antistress test at the test position of the tested panel. The local antistress test platform of the present invention can easily locate the antistress test position due to the adjustability thereof and be adaptable to the panel test for panels of different sizes.

With the fixing element, the antistress test platform of the present invention not only has good adaptability and easy operationality, and also promotes the test reliability and repeatability of the test results. During the antistress test, the test frame 300 can be located above the tested panel and the movable test hole table 302 can be fixed on the rolling guide 303. In this embodiment, the combination of the fixing hole and the fixing nut 305 is utilized to achieve the aforesaid fixture. Then, required weights are added to the weight test rod 301 to proceed the local antistress test at the test position of the tested panel. Accordingly, it can be ensured that the movable test hole table 302 is not moved during the antistress test to promote the reliability of the antistress test.

By utilizing the local antistress test platform of the present invention, the antistress test for several test positions can be proceeded with merely one location of the test frame 300. Therefore, the dividing rule 307 of the test frame 300 is capable of locating the several test positions more precisely. If two dividing rules 307 are attached to the two sides of the test frame 300, it is preferable to attach the two dividing rules 307 relatively (the scale of one dividing rule 307 gradually increases and the scale of the other dividing rule 307 gradually decreases from one end of the test frame 300 to the other end). Accordingly, the precise location of the antistress test position can be derived as the antistress tests are proceeded along either direction of the test frame 300.
The weight test rod 301 is positioned on the movable test hole table 302. The antistress test position hides in the movable test hole table 302 where the operator cannot see. The location of the antistress test position of the tested panel is inconvenient. The indicator positioned on the dividing rule 307 for pointing the antistress test position of the weight test rod 301 on the tested panel eliminates the aforesaid inconvenience. Once the movable test hole table 302 is located to the position corresponding to the indicator of the dividing rule 307, and then the weight test rod 301 is located at the antistress test position on the tested panel which the operator demands and achieve the precise location for the antistress test position.
The present invention also relates to a local antistress test apparatus. The local antistress test apparatus utilizes the aforesaid local antistress test platform for proceeding a local antistress test to a panel. The benefits and the embodiments can be referred to the aforementioned preferable embodiments of the local antistress test platform.
The workflow is introduced hereafter with the diagrams of the local antistress test platform according to the preferable embodiment of the present invention shown in
Preparation:
As shown in
Test:
The tested panel is placed on a tabletop which is level, steady and not deformable.
The test frame 300 of the local antistress test platform is now located above the tested panel. The weight test rod 301 is moved along the rolling guide 303 and located at the antistress test position by utilizing the movable test hole table 302. (The location can be achieved by utilizing the indicator of the dividing rule 307). The fixing nut 305 is screwed tie to fix the movable test hole table 302.
The required weights are added to the weight test rod 301 to proceed the local antistress test at the panel test position through the hole of the movable test hole table 302. The stress remains for one minute before the weights are removed. Then, the judgment of the local antistress ability is executed with powering up the panel after five minutes.
The aforesaid test steps are repeated for different test position and the local antistress tests with different weights.
The verticality of the weight test rod 301 is extremely demanded during the antistress test. Friction between the weight test rod 301 and the weights needs to be avoided as possible to prevent the unbalance and inaccuracy of the stress.
As the panel test is proceeded with the local antistress test platform of the present invention, the test platform only needs to be moved three times for the five point local antistress tests of the whole tested panel. Furthermore, the test platform with fixing holes according to prior occupies a large space. On the contrary, the extent of the local antistress test platform according to the present invention only needs to be slightly longer than the short side of the panel. As proceeding the test for the large panel, such as for the 16:9 main stream panel, the length L of the test platform is required to be larger than the panel width b as proceeding the test at the test position shown in
As is understood by a person skilled in the art, the foregoing preferred embodiments of the present invention are illustrative rather than limiting of the present invention. It is intended that they cover various modifications and similar arrangements be included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structure.
