DETAILED DESCRIPTION

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0018] like Figures 2 to 7 The steel mesh nano coating test experimental device shown includes a positioning platform 1 and a testing mechanism. The positioning platform 1 is used to position the steel mesh frame 2. The testing mechanism includes: A U-shaped guide rail frame 4, which is fixedly connected to the top of the positioning platform 1, a driving block 5 is slidably connected to the top of the U-shaped guide rail frame 4, and a cylinder 6 is fixedly connected to the bottom of the driving block 5; A detection seat, the top of which is arranged at the bottom of the cylinder 6, the bottom of which is rotatably connected to a turning frame 9, and a friction block 10 is arranged at the bottom of the turning frame 9; A U-shaped mounting frame 12, which is arranged on the detection seat, and an end of the U-shaped mounting frame 12 is symmetrically rotated and connected to an L-shaped mounting plate 13; An L-shaped tape 17 is slidably arranged on the side wall of the L-shaped mounting plate 13 along the track of the L-shaped mounting plate 13. The L-shaped tape 17 has an adhesive surface 1701 and a non-adhesive surface 1702. The adhesive surface 1701 contacts the nano coating on the surface of the steel mesh, and the non-adhesive surface 1702 contacts the bottom of the friction block 10. A first flip driving assembly, the first flip driving assembly is used to drive the L-shaped mounting plate 13 to flip; A second flipping drive assembly, the second flipping drive assembly is used to drive the flip frame 9 to flip; The test seat includes: A sliding seat 7, the top end of which is fixedly connected to the bottom end of the telescopic rod of the cylinder 6; A connecting rod 8, the top end of the connecting rod 8 is slidably connected in the sliding seat 7, the top side wall of the connecting rod 8 is fixedly connected with a first pressure sensor 11, the first pressure sensor 11 is fixedly connected to the side wall of the sliding seat 7, and a U-shaped mounting bracket 12 is fixedly connected to the outer side wall of the connecting rod 8; In the prior art, during the process of testing the smoothness of the nano coating on the surface of the steel mesh, the surface of the steel mesh and the test part are exposed to the outside for a long time, which easily causes dust in the air to adhere to the steel mesh and the test part, thereby increasing the roughness of the nano coating on the surface of the steel mesh and the test part, which easily increases the measurement error and is not conducive to accurate measurement. The technical solution can solve the above problem. The specific operation is as follows: first, the steel mesh frame 2 is placed on the positioning table 1, and the steel mesh frame 2 is positioned by the positioning table 1. The positioning can be performed by using the tightening block 38 and the tightening nut 39, so that the steel mesh remains stable during the test; After the steel mesh frame 2 is positioned, the cylinder 6 is started, so that the telescopic rod of the cylinder 6 pushes the detection seat to move downward, so that the U-shaped mounting frame 12 moves downward, and the L-shaped mounting plate 13 moves downward until the adhesive surface 1701 at the bottom of the L-shaped tape 17 contacts the nano coating on the surface of the steel mesh; Then, the driving block 5 drives the cylinder 6 to move linearly to the right along the U-shaped guide frame 4 manually or electrically, so that the L-shaped tape 17 moves along the surface of the steel mesh, and the dust on the surface of the steel mesh is cleaned through the adhesive surface 1701 of the L-shaped tape 17 to reduce the amount of dust on the surface of the steel mesh, thereby reducing the influence of dust on the surface roughness of the steel mesh and improving the test accuracy; Furthermore, during the process of the L-shaped tape 17 removing dust from the surface of the steel mesh, the friction block 10 is in contact with the non-stick surface 1702 of the L-shaped tape 17, thereby sealing the contact portion of the friction block 10, which is beneficial to reducing dust from falling onto the friction block 10, thereby reducing the influence of dust on the surface roughness of the friction block 10, and improving the test accuracy; After the steel mesh measurement is completed, the cylinder 6 is used to first move the L-shaped mounting plate 13 and the L-shaped tape 17 away from the steel mesh, and then the first flipping drive assembly is used to flip the L-shaped mounting plate 13 to make way for the flipping of the friction block 10, and then the second flipping drive assembly is used to rotate the flipping frame 9 so that the bottom of the friction block 10 faces downward, and then the cylinder 6 is used to make the friction block 10 contact with the surface of the steel mesh, and by pushing the movement of the driving block 5, the friction block 10 is moved along the cleaned surface of the steel mesh. During the movement, the friction block 10 generates friction with the surface of the steel mesh, so that the connecting rod 8 squeezes the first pressure sensor 11, so that the pressure value of the first pressure sensor 11 increases, and the smoothness of the steel mesh surface is measured according to the pressure value measured by the first pressure sensor 11.

In the process of the L-shaped tape 17 moving along the surface of the steel mesh, the L-shaped tape 17 slides downward due to the viscosity, so that the first installation roller 14 rotates to release the wound L-shaped tape 17. In the process of the first installation roller 14 rotating, the second installation roller 15 rotates under the transmission of the belt 35, thereby tightening the L-shaped tape 17 released by the first installation roller 14, which is conducive to keeping the L-shaped tape 17 in a taut state, thereby keeping the L-shaped tape 17 in full contact with the surface of the steel mesh, improving the dust removal effect, reducing the dust content, and then reducing the influence of dust on the surface roughness of the steel mesh, thereby improving the test accuracy. In addition, in the process of the L-shaped tape 17 continuously rotating to clean the dust on the surface of the steel mesh, the clean L-shaped tape 17 can always be in contact with the steel mesh, thereby further improving the dust removal effect, reducing the dust content, and then reducing the influence of dust on the surface roughness of the steel mesh, thereby improving the test accuracy; And during the movement of the L-shaped tape 17, it will produce friction with the friction block 10, which is helpful to clean the dust on the surface of the friction block 10, and because the friction block 10 is in contact with the non-sticky surface 1702 of the L-shaped tape 17, it is helpful to reduce the residual tape film adhering to the friction block 10.

The first limit slide rod 32 is fixedly connected to the L-shaped mounting plate 13 to limit the flipping angle of the L-shaped mounting plate 13.

[0022] As a further embodiment of the present invention, the second flip drive assembly comprises: A second drive motor 30, the second drive motor 30 is fixedly connected to the bottom end of the connecting rod 8, and the output shaft of the second drive motor 30 is coaxially fixed with the turning frame 9; Specifically, by setting a second drive motor 30, after the L-shaped mounting plate 13 is flipped, the second drive motor 30 is started, so that the output shaft of the second drive motor 30 rotates, so that the flip frame 9 rotates, so that the friction block 10 is in contact with the surface of the steel mesh; As a further implementation, a second arc-shaped slide groove 33 is opened at the bottom end of the connecting rod 8, and a second limiting slide rod 34 is slidably connected in the second arc-shaped slide groove 33.

At this time, the pressure value of the second pressure sensor 19 is the initial value. During the movement of the friction block 10 on the surface of the steel mesh, it is affected by the thickness of the nanolayer on the surface of the steel mesh. If the thickness of the nanolayer increases, the pressure between the friction block 10 and the steel mesh will increase, causing the friction force to increase, otherwise it will decrease, thereby increasing the measurement error. By setting the second pressure sensor 19, during the movement of the friction block 10 along the surface of the steel mesh, the pressure value measured by the second pressure sensor 19 exceeds or is lower than the preset value. By starting the drive motor 21, the screw rod 22 rotates, thereby adjusting the position of the second pressure sensor 19, so that the pressure value measured by the second pressure sensor 19 is restored to the initial value, thereby improving the measurement accuracy.

[0024] As a further embodiment of the present invention, the friction block 10 and the sliding rod 18 are connected by threads; Specifically, by threading the friction block 10 and the sliding rod 18 , it is convenient to remove the friction block 10 for replacement or maintenance.

[0026] When the pressure value detected by the second pressure sensor 19 exceeds the preset value, a first request message is generated. The second pressure sensor 19 sends the first request message to the controller 3.

The positioning can be performed by using the tightening block 38 and the tightening nut 39, so that the steel mesh remains stable during the test; After the steel mesh frame 2 is positioned, the cylinder 6 is started, so that the telescopic rod of the cylinder 6 pushes the detection seat to move downward, so that the U-shaped mounting frame 12 moves downward, and the L-shaped mounting plate 13 moves downward until the adhesive surface 1701 at the bottom of the L-shaped tape 17 contacts the nano coating on the surface of the steel mesh; Then, the driving block 5 drives the cylinder 6 to move linearly to the right along the U-shaped guide frame 4 manually or electrically, so that the L-shaped tape 17 moves along the surface of the steel mesh, and the dust on the surface of the steel mesh is cleaned through the adhesive surface 1701 of the L-shaped tape 17 to reduce the amount of dust on the surface of the steel mesh, thereby reducing the influence of dust on the surface roughness of the steel mesh and improving the test accuracy; Furthermore, during the process of the L-shaped tape 17 removing dust from the surface of the steel mesh, the friction block 10 is in contact with the non-stick surface 1702 of the L-shaped tape 17, thereby sealing the contact portion of the friction block 10, which is beneficial to reducing dust from falling onto the friction block 10, thereby reducing the influence of dust on the surface roughness of the friction block 10, and improving the test accuracy; After the steel mesh measurement is completed, the cylinder 6 is used to first move the L-shaped mounting plate 13 and the L-shaped tape 17 away from the steel mesh, and then the first flipping drive assembly is used to flip the L-shaped mounting plate 13 to make way for the flipping of the friction block 10, and then the second flipping drive assembly is used to rotate the flipping frame 9 so that the bottom of the friction block 10 faces downward, and then the cylinder 6 is used to make the friction block 10 contact with the surface of the steel mesh, and by pushing the movement of the driving block 5, the friction block 10 is moved along the cleaned surface of the steel mesh. During the movement, the friction block 10 generates friction with the surface of the steel mesh, so that the connecting rod 8 squeezes the first pressure sensor 11, so that the pressure value of the first pressure sensor 11 increases, and the smoothness of the steel mesh surface is measured according to the pressure value measured by the first pressure sensor 11.
