Description

Technical Field

[0001] The utility model relates to the field of water contact angle testing, in particular to a sample supply mechanism used in a water contact angle testing instrument. Background Art

[0002] Characterizing the hydrophilicity of a sample's surface plays a crucial role in glass coating testing, printing adhesion analysis, analysis of specialized chemical coatings, and LED circuit board cleanliness analysis. This characterization is typically performed by measuring the water contact angle of a sample using a water contact angle tester. This tester consists of a lens and a test platform. The test platform, located below the lens and used to place the sample for lens testing, is supported by a support that can move the test platform vertically, forward and backward, and side to side. For small-sized samples that can be completely placed on the test platform, they can be placed directly on the test platform. When different positions of the sample need to be observed, continuous testing of the sample can be achieved by simply moving the test platform. For large-sized samples that cannot be completely placed on the test platform (especially when the sample width is equal to or less than the width (or length) of the test platform, but the sample length is much longer than the length (or width) of the test platform), it is often necessary to cut the sample into small-sized samples that can be completely placed on the test platform. However, after cutting, the test sites are often located on different small-sized samples, resulting in the need to frequently replace samples during testing, which makes continuous testing impossible, affecting test efficiency.

[0024] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] refer to Figure 1 , shows a sample supply mechanism of the utility model applied to a water contact angle tester, comprising:

[0027] A first reel is mounted on a support portion (e.g., a base of the support portion) of a test platform of a water contact angle tester via a support rod and is located on one side of the test platform;

[0028] a second reel mounted on the support portion (e.g., a base of the support portion) via a support rod, located on the other side of the test platform and parallel to the first reel;

[0029] The sample to be tested is wound on the first reel, and the sample after testing is wound on the second reel; or

[0030] The sample to be tested is wound on the second reel, and the sample after testing is wound on the first reel;

[0031] The portion of the sample to be tested located between the first reel and the second reel covers the test platform for testing.

[0032] Preferably, the length of the first reel is equal to the length of the second reel.

[0033] Preferably, the lengths of the first and second reels are longer than the size of the test platform (ie the length of the platform's sides parallel to the two reels is less than the lengths of the two reels, so as to facilitate winding around samples of various widths).

[0034] In this embodiment, when performing a water contact angle test on a sample of a larger size, for example, it is first wound around the first reel, and then the test is opened from one end of the sample, and the first reel is rotated to gradually release the sample to test other sites to be tested on the sample; as the length of the sample after the test is completed gradually increases, when the end of the sample to be tested reaches the second reel, it is wound around the second reel, and then the second reel is rotated (for example, by manually rotating the second reel) to pull the sample from the first reel to be gradually released to complete subsequent testing; similarly, the sample to be tested can also be wound around the second reel first, and the sample to be tested can be gradually wound around the first reel. The sample supply mechanism of the embodiment of the utility model is suitable for the testing of large-sized samples, especially samples with a long length, and can realize continuous testing of samples without cutting the samples, saving testing time and improving testing efficiency. At the same time, since there is no need to cut the samples, contamination caused by cutting is also avoided. It should be noted that since the first and second scrolls are both mounted on the support portion of the test platform, when the test platform is moved, the support portion drives the first and second scrolls to move along with the test platform, i.e., the relative positions of the test platform, the first and second scrolls remain fixed. It should be noted that, generally speaking, large-sized samples in the present invention generally refer to samples of relatively long lengths, and their widths need to meet the dimensional requirements of the test platform. If the width is larger than the size of the test platform, it only needs to be cut in the width direction to meet the requirements of the test platform.

[0035] Example 2

[0036] refer to Figure 2 and Figure 3 On the basis of the first embodiment, a driving component is added to the support portion to drive the second reel to rotate.

[0037] The driving assembly includes a driving motor, the output end of which is equipped with a driving wheel;

[0038] The second reel is provided with a driven wheel, and the driving wheel is in transmission connection with the driven wheel.

[0039] In this embodiment, the motor is fixedly mounted on the support portion and can move with the support portion; the driving wheel mounted on the output end of the motor is driven by the motor to rotate, and the driving wheel is driven by a belt ( Figure 2 and Figure 3 In the embodiment, the sample to be tested is first wound on the first reel, and the motor drives the driving wheel to rotate the driven wheel, gradually winding the tested sample on the second reel. At the same time, the untested sample is pulled and released from the first reel to be tested.

[0040] Example 3

[0041] refer to Figure 3 On the basis of the first embodiment, a driving component is added to the support portion to drive the first scroll to rotate.

[0042] The driving assembly includes a driving motor, the output end of which is equipped with a driving wheel;

[0044] In this embodiment, the motor is fixedly mounted on the support portion and can move with the support portion; the driving wheel mounted on the output end of the motor is driven by the motor to rotate, and the driving wheel is driven by a belt ( Figure 4 In the embodiment, the sample to be tested is first wound around the second reel, and the motor drives the driving wheel to rotate the driven wheel, gradually winding the tested sample around the first reel. At the same time, the untested sample is pulled and released from the second reel to be tested.
