Description

Technical Field

[0001] The present application relates to the technical fields of testing, measurement and image processing, and in particular to a water drop angle testing method and system. Background Art

[0002] The droplet angle, also known as the water contact angle, describes the contact angle formed by a liquid on a solid surface. Specifically, it is the angle between the gas-liquid interface and the solid-liquid interface at the solid-liquid-gas three-phase interface when a liquid droplet (usually double-distilled water) reaches equilibrium on the solid surface.

[0003] At present, the optimization of the accuracy of water drop angle testing only takes into account the errors in subsequent water drop angle testing caused by the unstable changes of the test liquid due to the influence of external forces during the dripping process. It does not further consider the changes in the surface tension of the test liquid caused by the adhesion of a certain concentration of particles in the external environment before the test liquid contacts the object, which ultimately leads to large errors in the test results and reduces work efficiency.

[0035] The specific step S3 includes the following sub-steps: A second test plan is formulated. According to the second test plan, a second test liquid height threshold value is preset. According to the second test liquid height threshold value, a second test liquid amount and a second dripping speed for dripping the test liquid are set. The second test liquid amount and the second dripping speed are conditions that can maintain the test liquid in a stable shape during the dripping process.

[0036] According to the second test liquid volume, the lower surface area of ​​the second test liquid during the dripping process is calculated to obtain the second test liquid area.

According to the test object flatness constraint condition, a matching test of the above-mentioned angle test simulation model can be performed or a formula can be applied to predict the contact angle value between the second test pre-treated object and the test liquid in the second test scheme to obtain the predicted angle one, if they are b1°, b2°, b3°, b4°, and b5° respectively).

[0041] The specific step S4 includes the following sub-steps: A third test plan is formulated. According to the third test plan, a third test liquid height threshold is preset. According to the third test liquid height threshold, a third test liquid amount and a third dripping speed for dripping the test liquid are set. The third test liquid amount and the third dripping speed are conditions that can maintain a stable shape of the test liquid during the dripping process.

[0044] The third test liquid height threshold, the third test liquid volume, the third dripping speed, the third test liquid area and the ambient particle concentration value are combined into a third test feature information set.

[0045] The third test feature information set and the flatness of the test object are input into the angle test simulation model for testing to obtain the predicted angle 2.

[0046] Specifically, such as the test liquid height threshold three (if it is 2 cm), the third test liquid volume (if the test liquid volume is 2µl) and the third dripping speed (V3), the third test liquid area (if the radius is 1 mm, the lower surface area is 1π square millimeters), the third pre-treated test object (that is, the second pre-treated test object is cleaned again after being in contact with the test liquid in the second test scheme, that is, the cleaning process is the same as the cleaning process of the first pre-treated test object, which is not explained in detail here), and the predicted angle two (that is, the obtained test liquid height threshold three, the third test liquid volume, the third dripping speed, the third test liquid area, the ambient particle concentration value, the third test feature information set and the test object flatness.
