A water drop angle tester and test method

Abstract

The invention provides a water drop angle test instrument and a test method. The test instrument comprises a case, a storage part, a liquid dripping part, a platform part, an illumination part, an image pickup part, a processing part and a temperature control part, wherein the platform part comprises a fine adjusting device; a test piece is fixed on the sample table through the fine adjusting device; an adjusting part and the fine adjusting device are used for adjusting the flatness degree of samples put on the platform part; a steering part arranged at one side of the image pickup part is used for regulating the inclination angle of the platform part, so that the image pickup part and the platform part are always positioned on the same horizontal line. The automatic control mode is used,so that the problem of low test precision due to manual control requirement in the prior art is solved; the effects of high precision, wide application range and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of test devices, and in particular relates to a water drop angle tester and a test method. [0002] technical background [0003] The current water drop angle tester generally places and clamps the sample manually, which will lead to inaccurate placement of the test piece, and the clamping force is not strong, resulting in the surface of the sample not being in a horizontal state, resulting in the angle of the dripping liquid Inaccurate, affect the test results. In addition, the current device can only test the static water drop angle or the dynamic water drop angle alone, and cannot perform these two tests on the sample at the same time, resulting in low efficiency. In addition, the current equipment cannot automatically adjust the height of the camera, and can only use samples of one thickness, or adjust the height manually, resulting in inaccurate test results.
