[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0035] In order to perform multiple hardness tests on the hydrophilic coating at one time to obtain a comprehensive test analysis structure, a hydrophilic coating hardness test and analysis device is proposed;

[0036] Please refer to Figure 1 - Figure 8 , including a first housing 1, a test material 101 and a conveying mechanism 2 are arranged in the first housing 1, and the conveying mechanism 2 is used to drive the test material 101 to perform a horizontal linear motion in the first housing 1;

[0037] An engraving mechanism 6 is arranged on the first housing 1, and the engraving mechanism 6 includes a press head assembly 7, a lifting component 8 and an indexing component 9;

[0038] The press head assembly 7 includes a plurality of engraving press heads 704 arranged in the first housing 1;

[0039] The lifting component 8 is used to drive the plurality of engraving press heads 704 to perform a vertical lifting motion in the first housing 1;

[0040] The indexing component 9 is connected to each of the plurality of engraving press heads 704 to realize its rotation for position change, and cooperates with the lifting component 8 to form a plurality of test indentations on the surface of the test material 101.

[0041] Among them, the test material 101 is a hydrophilic coating material to be tested. The conveying mechanism 2 is arranged on the first housing 1. Through the conveying mechanism 2, the test material 101 can be driven to move linearly back and forth in the first housing 1.

[0042] A total of three engraving indenters 704 are arranged in the indenter assembly 7. They are indenters of three different shapes and materials and can be replaced according to actual situations. For example, a regular square pyramid diamond indenter for Vickers hardness test, an alloy ball for Rockwell hardness test, etc.

[0043] The lifting assembly 8 is used to drive the three engraving indenters 704 to move linearly vertically in the first housing 1, and the indexing assembly 9 is used to drive the three engraving indenters 704 to rotate for indenter switching.

[0044] During the test, first, the conveying mechanism 2 drives the test material 101 to move forward to the position where the three engraving indenters 704 are located and then stops the transmission. Then, the lifting assembly 8 drives the three engraving indenters 704 to move downward. At this time, one of the engraving indenters 704 will press on the surface of the test material 101 to form a test indentation.

[0045] Then, the lifting assembly 8 drives the three engraving indenters 704 to move upward away from the test material 101, and the indexing assembly 9 is used to reposition the three engraving indenters 704. Then, the conveying mechanism 2 drives the test material 101 to move forward a short distance, and then the lifting assembly 8 drives the three engraving indenters 704 to move downward to form another test indentation.

[0046] Similarly, a third test indentation can be formed on the test material 101. Finally, through the analysis of the three test indentations, a comprehensive test analysis result can be obtained. Embodiment

Two electric push rods 104 are symmetrically arranged in the first housing 1.

[0049] Among them, the reading microscope 102 is installed on the front side part of the first housing 1. After three different indentations are formed on the test material 101 through the cooperation of the conveying mechanism 2 and the engraving mechanism 6, the conveying mechanism 2 drives the test material 101 to continue to move forward to stop at the position of the reading microscope 102. Then, the three indentations are measured by the reading microscope 102, and the obtained data is transmitted to the display screen 103 for display.

[0050] In addition, in order to make the test material 101 more stable when receiving the engraving of the three engraving punches 704, two electric push rods 104 are symmetrically installed on the left and right inner walls of the first housing 1. When the conveying mechanism 2 drives the test material 101 to reach the lower side of the engraving punch 704, the two electric push rods 104 operate and extend simultaneously, and the test material 101 can be clamped and fixed in the middle to receive the engraving of the three engraving punches 704. After the engraving is completed, the two electric push rods 104 operate and contract to release the test material 101. Embodiment

[0051] In order to carry the three engraving punches 704 to move up and down and rotate and change positions in the first housing 1, Embodiment 3 is proposed;

The turntable 703 is rotatably arranged on the surface of the fixed disk 702. The three engraving punches 704 are respectively fixedly installed at the lower end of the turntable 703 and are evenly arranged in a fan shape. Through the turntable 703, one of the engraving punches 704 can be vertically downward aligned with the test material 101. Embodiment

The first rack 803 is oval, and its left and right inner walls are distributed with linear teeth.

[0058] When the second spur gear 802 meshes with the teeth on the right side of the first rack 803, the second motor 801 operates to drive the second spur gear 802 to rotate. The second spur gear 802 will then drive the first rack 803 to move downward, and further drive the second housing 701 to move downward until the second spur gear 802 rotates out of contact with the teeth on the right side of the first rack 803. Then the second spur gear 802 will rotate to mesh with the teeth on the left side of the first rack 803, and further drive the first rack 803 to move upward. In this way, reciprocating up and down linear motion of the second housing 701 can be realized.

[0059] In addition, limiting blocks 805 are fixed at both the left and right ends of the second housing 701. First limiting grooves 806 are formed on both the left and right inner walls of the first housing 1. The two limiting blocks 805 can respectively slide up and down in the two first limiting grooves 806 to support and limit the second housing 701. Embodiment

[0063] By rotating the second rotating rod 903, the second bevel gear 904 can be driven to rotate, thereby driving the first bevel gear 902 and the first rotating rod 901 to rotate, and further driving the turntable 703 and the three engraving heads 704 to rotate for the switching of the engraving heads. Embodiment

[0064] In order to enable the device to automatically switch the three engraving heads 704 and facilitate operation, Embodiment 6 is proposed;
