Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coating adhesion testing equipment, and more specifically, to a coating adhesion testing equipment for metal substrate surfaces. Background Technology
[0002] With the continuous development of industry, metal substrates have been widely used in various fields, such as aerospace, automobile manufacturing, construction, and machinery. In these applications, the surface properties of the metal substrate are crucial. To improve its corrosion resistance, wear resistance, decorative properties, and to endow it with special functions, it is usually necessary to coat the surface of the metal substrate with one or more layers of coating. However, the adhesion between the coating and the metal substrate is a key factor affecting the coating's performance and service life. If the adhesion is insufficient, the coating may peel off or flake during use, leading to a decline in the performance of the metal substrate and even causing safety accidents.
[0003] Existing coating adhesion testing methods typically only allow for a single type of test, failing to comprehensively and accurately assess the bonding performance between the coating and the metal substrate. For example, the cross-cut test can only observe the surface peeling of the coating, but cannot measure the internal bonding strength of the coating, nor can it simultaneously assess the changes in the coating's bonding strength under different environmental conditions. This single-type testing method often results in poor testing results.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] Furthermore, in order to better ensure the adjustment and switching effect, the output shaft of the first motor is equipped with an adjustment gear, which meshes with an adjustment rack. A switching plate is fixedly installed on one side of the adjustment rack, and one end of the switching plate is slidably connected to the bottom end of the adjustment frame.
[0009] Furthermore, to better ensure the limiting effect, a micro motor is provided on one side of the switching plate. The output shaft of the micro motor is provided with a first bidirectional threaded rod through a coupling. An adjustment groove is provided at the bottom of the switching plate. One end of the first bidirectional threaded rod extends into the interior of the adjustment groove and connects with the inner wall of the adjustment groove.
[0010] Furthermore, in order to better ensure the detection effect, a first limit block is threadedly connected to the first bidirectional threaded rod, and multiple adjusting springs are provided at the bottom of the switching plate. A pressure detection block is provided at one end of the adjusting spring, and a pressure sensor is embedded in one end of the pressure detection block.
[0011] Furthermore, in order to better ensure the limiting effect on the metal substrate, the auxiliary component includes a mounting frame. A second motor is provided on one side of the mounting frame. The output shaft of the second motor is provided with a second bidirectional threaded rod through a coupling. One end of the second bidirectional threaded rod extends into the interior of the mounting frame and is connected to the inner wall of the mounting frame.
[0012] Furthermore, for better limiting and guiding effect, multiple second limiting blocks are threadedly connected to the second bidirectional threaded rod, and guide rods are slidably connected to the second limiting blocks, with the guide rods connected to the inner wall of the mounting frame.
[0013] Furthermore, to better ensure further limiting, a second electric push rod is provided on one side of the second limiting block, and an adjustment plate is provided on the moving end of the second electric push rod, and the adjustment plate is adapted to the second limiting block.
[0014] The beneficial effects of this utility model are as follows: through the cooperation of the detection component and the auxiliary component, it is possible to achieve multi-angle and multi-mode detection of the bonding force of the coating on the surface of the metal substrate, overcoming the defects of the existing technology that the detection method is single and cannot comprehensively and accurately evaluate the bonding force. Specifically, the first electric push rod, the first motor, the adjusting gear, the adjusting rack and the micro motor in the detection component can achieve precise adjustment of the detection force and the detection position, so that the pressing detection block can detect the coating with appropriate force and angle, thereby more accurately measuring the bonding strength between the coating and the metal substrate. At the same time, the second motor, the second bidirectional threaded rod, the second limiting block and the second electric push rod in the auxiliary component can stably fix the metal substrate and flexibly adjust its position, ensuring the stability of the metal substrate and the accuracy of the detection during the detection process.

[0027] Example 2:
[0028] like Figures 1-5 As shown, according to an embodiment of the present invention, an auxiliary component 3 of a metal substrate surface coating adhesion testing device includes a mounting frame 301. A second motor 302 is provided on one side of the mounting frame 301. The output shaft of the second motor 302 is provided with a second bidirectional threaded rod 303 via a coupling. One end of the second bidirectional threaded rod 303 extends into the interior of the mounting frame 301 and is connected to the inner wall of the mounting frame 301.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0030] In summary, with the help of the above-mentioned technical solution of this utility model, when tensile testing is required, the second motor 302 drives the second bidirectional threaded rod 303 to rotate, causing the second limiting block 304 to move from both sides towards the center within the mounting frame 301, adjusting the position of the placed metal substrate. The guide rod 305 guides the movement of the second limiting block 304, ensuring its smooth movement. The second electric push rod 306 drives the adjusting plate 307 to move, firmly clamping the metal substrate between the second limiting blocks 304 to prevent displacement during testing. Then, the first electric push rod 202 drives the adjusting frame 203 to move up and down, adjusting the position of the metal substrate. The height of the measuring device is adjusted to the height position of the metal substrate held by the adjusting plate 307. Then, the first motor 204 drives the adjusting gear 205 to rotate. Through meshing with the adjusting rack 206, the switching plate 207 slides along the bottom end of the adjusting frame 203, so that the first limiting block 210 is located directly above the held metal substrate. Then, the micro motor 208 on the switching plate 207 drives the first bidirectional threaded rod 209 to rotate, so that the first limiting block 210 moves in the adjusting groove 5 to clamp the other end of the metal substrate. Then, the moving end of the first electric push rod 202 retracts, thereby realizing the tensile test of the metal substrate.
[0031] When performing indentation detection on a metal substrate, the first electric push rod 202 drives the adjustment frame 203 to move up and down, adjusting the height of the detection device to the height position of the metal substrate held by the adjustment plate 307. Then, the first motor 204 drives the adjustment gear 205 to rotate, and through meshing with the adjustment rack 206, drives the switching plate 207 to slide along the bottom end of the adjustment frame 203, so that the first limit block 210 is located directly above the held metal substrate. Then, the moving end of the first electric push rod 202 drives the switching plate 207 to descend, so that the pressure detection block 212 contacts the held metal substrate to generate an indentation. During the pressing process, the adjustment spring 211 provides a stable downward force for the pressure detection block 212 to ensure that the detection block is in close contact with the coating surface. The pressure sensor 213 built into the pressure detection block 212 monitors the magnitude of the downward force in real time and transmits the data to the controller 4 to achieve precise control and monitoring of the detection force.
[0032] After the initial inspection, in order to analyze the microstructure and damage of the coating in more depth, a microscope is used to conduct a detailed inspection of the inspection location. The microscope can provide a high magnification effect, which helps operators observe subtle changes on the coating surface, such as microcracks, peeling marks, and the bonding interface between the coating and the metal substrate. This process is of great significance for evaluating the integrity and performance of the coating, and can provide more detailed data support for subsequent quality control and process optimization.
