Description

Technical Field

[0001] This invention relates to the field of performance testing technology for floor coatings, and in particular to a testing device and method for testing the anti-corrosion performance of floor coatings. Background Technology

[0002] Industrial flooring, used in commercial and industrial settings, requires enhanced wear resistance of concrete surfaces. Increasing the density of the concrete surface reduces dust generation, improves oil resistance, and creates a high-density, easy-to-clean, impermeable surface with a certain degree of gloss and stain resistance. Industrial flooring necessitates the use of floor coatings, which must possess excellent corrosion resistance; therefore, corrosion resistance testing of the floor coatings is required.

[0003] Existing quality testing equipment for anti-corrosion floor coating production and processing typically relies on manual inspection by workers. This method is not only ineffective but also inefficient, time-consuming, and inconvenient for staff. In practice, testing usually involves immersing the coated test panel in a single acid or alkali solution. While corrosion is detected in this solution, it's difficult to accurately determine the specific acidity or alkalinity at which the coating is corroded. This low accuracy prevents precise identification of the acidity or alkalinity at which the coating layer is corroded, hindering the optimization of the anti-corrosion process. It is then necessary to replace the coated test panel with one in a lower concentration solution for accurate assessment of the anti-corrosion performance. However, this method is cumbersome, increases workload, and requires more test panels, thus raising testing costs. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a testing device and method for the anti-corrosion performance of floor coatings.

A mobile inspection mechanism, comprising an inspection plate externally coated with a floor paint layer, a mounting base for mounting the inspection plate, a lifting assembly for driving the mounting base to rise and fall, and a rotating assembly for driving the lifting assembly to rotate in a circular motion; and A pick-and-place seat, which is fixed to the side of the protective shell and the detection seat, is used for placing and removing the detection plate; The rotating assembly includes a rotating seat that slides on the inner wall of the protective shell, a drive motor is fixedly mounted on the rotating seat, the output shaft of the drive motor is connected to a drive gear, an upper gear ring that meshes with the drive gear is fixedly mounted on the inner wall of the protective shell, and an annular groove for the movement of the rotating seat is opened on the inner wall of the protective shell. The lifting assembly includes a reciprocating lead screw rotatably connected to the bottom of the rotating seat. A driven gear is fixedly provided at the bottom of the reciprocating lead screw. A lower toothed ring that meshes with the driven gear is fixedly provided on the inner side wall of the protective shell. A sleeve is threadedly connected to the outer side of the reciprocating lead screw. The sleeve is fixedly connected to the mounting seat. A telescopic rod is provided between the mounting seat and the rotating seat.

[0006] Preferably, the mounting base includes a connecting plate fixedly connected to the sleeve, side plates are provided on both sides of the connecting plate, and two limiting rods are symmetrically arranged between the two side plates, and the detection plate moves between the two limiting rods.

[0007] Preferably, the detection plate includes a top horizontal plate and a vertical plate arranged below the horizontal plate, the vertical plate being movable between two limiting rods, and the floor paint layer being coated on the lower side of the vertical plate.

[0008] Preferably, two rotating rods are rotatably connected between the two side plates, each of the two rotating rods is provided with a synchronous pulley, a synchronous belt is provided between the two synchronous pulleys, each rotating rod is provided with a protrusion that moves against the detection plate, one of the rotating rods is provided with a worm gear, and the bottom of the reciprocating screw is provided with a worm that meshes with the worm gear.

[0009] Preferably, a separator block is provided between two adjacent detection slots, and a flow guiding slope is provided on the separator block.

[0010] Preferably, the pick-and-place base includes a pick-and-place shell fixed to the side of the protective shell and the detection base. Both sides of the pick-and-place shell are rotatably connected to a rotating shaft. Each rotating shaft is provided with a plurality of baffles distributed equidistantly in a circle. Each baffle is provided with a corrosion-resistant brush on the side away from the rotating shaft.

[0011] Preferably, a liquid storage tank is fixed inside the protective shell, and a solenoid valve is provided between the liquid storage tank and each detection tank. The solenoid valve, pH sensor and camera are all connected to the back-end terminal, and the back-end terminal is also electrically connected to a display screen.

[0012] This invention also discloses a testing method for a floor coating anti-corrosion performance testing device, comprising the following steps: S1: Apply floor paint to the bottom of the vertical plate of the test board to be tested. After the floor paint dries, a floor paint layer is formed on the bottom of the test board. Then, insert the vertical plate of the test board to be tested between the two limiting rods placed in the mounting seat inside the pick-and-place seat. Place detection solutions of progressively increasing concentrations into each detection slot on the detection stand, so that the detection solution concentrations in the detection slots on both sides of the placement and dispensing stand are at their lowest and highest values, respectively. S2: Then control the drive motor to run. The output shaft of the drive motor drives the drive gear to rotate. The drive gear meshes with the upper gear ring on the inner side wall of the protective shell, so that the rotating seat rotates around the inner side wall of the protective shell. When the rotating seat moves, it drives the driven gear at the bottom of the reciprocating screw to mesh with the lower gear ring on the inner side wall of the protective shell. The driven gear revolves around the protective shell while rotating on its own axis. The driven gear drives the reciprocating screw to rotate. When the reciprocating screw rotates, the sleeve connected by the outer thread moves up and down along its axial direction. The sleeve drives the mounting seat to rotate circumferentially while driving it to move up and down. When the detection plate rotates around the protective shell, it first moves to the detection tank with the lowest concentration value next to the pick-and-place seat. Then, the sleeve drives the detection plate to move downward along the reciprocating screw axis through the mounting seat, so that the floor paint layer at the bottom of the detection plate comes into contact with the detection solution in the detection tank. The detection plate continues to rotate around the protective shell in the detection tank. As the reciprocating screw continues to rotate, after the sleeve moves to the bottom of the reciprocating screw, it begins to drive the detection plate to move upward through the mounting seat. During the upward movement, the detection plate passes over the partition block between two adjacent detection tanks. Subsequently, after the sleeve moves up to the upper end of the reciprocating screw, it drives the detection plate to move down again through the mounting seat. During the rotation, the detection plate moves to the top of the second detection slot and continues to move down, so that the floor paint layer at the bottom of the detection plate is tested in a detection solution with a higher concentration. Repeat the above steps until the test plate moves to the last test tank, where the test solution with the highest concentration will perform anti-corrosion testing on the floor paint layer. S3: As the floor paint layer at the bottom of the test panel moves to the test tank one by one, the pH sensor in each test tank monitors the pH value of the test solution in the tank in real time, and the camera takes pictures and records the floor paint layer on the outside of the test panel, thereby testing the anti-corrosion performance of the floor paint layer. The pH sensor monitoring data and the camera image are displayed on the screen. If the pH sensor detects a decrease in the pH value of the test solution in the tank, it indicates that the test solution has reacted with the floor paint layer, and the floor paint layer on the outside of the test panel has been corroded. The camera can also monitor the corrosion of the floor paint layer in real time. After the floor paint layer is corroded in the test tank with different pH test solutions, its corrosion resistance can be accurately determined, which is convenient for subsequent staff to improve the anti-corrosion process of the floor paint layer. If the floor paint layer is still not corroded after the test panel is removed from the last test tank, it indicates that the anti-corrosion performance of the floor paint layer meets the production requirements.

[0013] Compared with the prior art, the present invention provides a testing device and method for the anti-corrosion performance of floor coatings, which has the following beneficial effects: 1. The floor coating corrosion resistance testing device and its testing method, through the movement of the testing plate driven by the moving testing mechanism, can conduct corrosion resistance tests on the floor coating layer on the testing plate with different concentrations of test solutions in a single test. It can accurately determine the acidity or alkalinity of the floor coating when it is corroded without repeatedly coating the testing plate, thereby accurately optimizing the anti-corrosion process of the floor coating. It is not only simple and convenient to operate, improving the efficiency of floor coating corrosion resistance testing, but also reducing the cost of floor coating corrosion resistance testing.

[0014] 2. The floor coating anti-corrosion performance testing device and its testing method utilize the rotation of the rotating seat to drive the driven gear at the bottom of the reciprocating screw to mesh with the lower gear ring on the inner side wall of the protective shell. The driven gear revolves around the protective shell while rotating on its own axis, driving the reciprocating screw to rotate. When the reciprocating screw rotates, the sleeve connected by the outer thread moves up and down along its axial direction. The sleeve drives the mounting seat to rotate circumferentially while also moving it up and down, causing the mounting seat to drive the test plate to rotate and move up and down repeatedly. This allows the test plates to enter the test tank with continuously increasing concentration one by one for testing, effectively improving the efficiency and accuracy of the floor coating anti-corrosion testing results.

[0015] 3. The floor coating corrosion resistance testing device and its testing method utilize the meshing transmission between the worm gear at the bottom of the reciprocating screw and the worm wheel on the rotating rod. The rotation of the worm wheel drives the connected rotating rod to rotate. This rotating rod, through a synchronous pulley and belt, drives another rotating rod to rotate. The rotation of the two rotating rods pushes the testing plate, which is positioned between two limiting rods, via a protrusion. This causes the testing plate to swing during the testing process. This improves the contact effect between the floor coating layer and the testing solution in the testing tank. Furthermore, it shakes off the testing solution as it moves out of the testing tank, preventing low-concentration testing solutions from moving into high-concentration testing solutions, which could lower the pH of the high-concentration solutions and affect the accuracy of the floor coating corrosion resistance test results.

[0016] 4. The floor coating corrosion resistance testing device and its testing method, by rotating baffles and corrosion-resistant brushes on both sides of the pick-and-place seat, can separate the pick-and-place seat from the protective shell, reduce the evaporation rate of some volatile acid or alkali solutions, effectively alleviate and avoid the evaporation of acid and alkali solutions, and reduce the cost of floor coating corrosion resistance testing.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A testing device for the anti-corrosion performance of floor coatings, comprising a protective shell 1, and further comprising: The detection seat 2 is fixed to the bottom of the protective shell 1. The detection seat 2 has several equally spaced detection slots 201. Each detection slot 201 contains a detection solution of different concentrations, and each detection slot 201 is equipped with a pH sensor 202 and a camera 203. The mobile testing mechanism includes a testing plate 3 with an external coating of floor paint 303, a mounting base 4 for mounting the testing plate 3, a lifting assembly for driving the mounting base 4 to rise and fall, and a rotating assembly for driving the lifting assembly to rotate in a circular motion; and The pick-and-place seat 5 is fixed to the side of the protective shell 1 and the detection seat 2, and is used for placing and taking out the detection plate 3.

[0022] Specifically, a floor paint is applied to the bottom of the test plate 3 to be tested. After the floor paint dries, a floor paint layer 303 is formed on the bottom of the test plate 3. Then, the test plate 3 is placed on the mounting base 4 inside the pick-and-place base 5. The moving test mechanism is then controlled to move the test plate 3. The anti-corrosion performance of the floor paint layer 303 on the test plate 3 can be tested with different concentrations of test solutions in a single test. The acidity or alkalinity of the floor paint when it is corroded can be accurately determined without repeatedly applying paint to the test plate 3. This allows for accurate optimization of the anti-corrosion process of the floor paint. The operation is not only simple and convenient, improving the efficiency of floor paint anti-corrosion testing, but also reducing the cost of floor paint anti-corrosion testing.

[0023] Example 2: Refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 A floor coating anti-corrosion performance testing device, based on embodiment 1, further includes a rotating component including a rotating seat 6 that slides on the inner wall of the protective shell 1, a drive motor 601 fixed on the rotating seat 6, a drive gear 602 connected to the output shaft of the drive motor 601, an upper toothed ring 603 that meshes with the drive gear 602 fixed on the inner wall of the protective shell 1, and an annular groove 604 for the movement of the rotating seat 6 on the inner wall of the protective shell 1.

[0024] Furthermore, the lifting assembly includes a reciprocating screw 7 rotatably connected to the bottom of the rotating seat 6. A driven gear 701 is fixedly provided at the bottom of the reciprocating screw 7. A lower gear ring 702 that meshes with the driven gear 701 is fixedly provided on the inner side wall of the protective shell 1. A sleeve 703 is threadedly connected to the outer side of the reciprocating screw 7. The sleeve 703 is fixedly connected to the mounting seat 4. A telescopic rod 704 is provided between the mounting seat 4 and the rotating seat 6.

[0025] Furthermore, the mounting base 4 includes a connecting plate 401 fixedly connected to the sleeve 703. Side plates 402 are provided on both sides of the connecting plate 401. Two limiting rods 403 are symmetrically arranged between the two side plates 402. The detection plate 3 moves between the two limiting rods 403.

[0026] Furthermore, the detection plate 3 includes a top horizontal plate 301 and a vertical plate 302 vertically disposed below the horizontal plate 301. The vertical plate 302 is movable between two limiting rods 403, and the floor paint layer 303 is coated on the lower side of the vertical plate 302.

[0027] Specifically, when the detection plate 3 is placed, the vertical plate 302 is positioned between the two limiting rods 403, and the horizontal plate 301 restricts the detection plate 3 from moving up and down on the mounting base 4. Floor paint is applied to the lower side of the vertical plate 302 to facilitate penetration into the detection groove 201 for corrosion testing. When the moving detection mechanism is working, the drive motor 601 is controlled to run. The output shaft of the drive motor 601 drives the drive gear 602 to rotate. The drive gear 602 meshes with the upper gear ring 603 on the inner wall of the protective shell 1, causing the rotating base 6 to rotate around the protective shell 1. When the inner wall rotates and the rotating seat 6 moves, it drives the driven gear 701 at the bottom of the reciprocating screw 7 to mesh with the lower gear ring 702 on the inner wall of the protective shell 1. The driven gear 701 revolves around the protective shell 1 while rotating on its own axis. The driven gear 701 drives the reciprocating screw 7 to rotate. When the reciprocating screw 7 rotates, the sleeve 703 connected by the outer thread moves up and down along its axial direction. The sleeve 703 drives the mounting seat 4 to rotate circumferentially while moving it up and down. When the detection plate 3 rotates around the protective shell 1, it first moves to the pick-and-place seat. Above the detection tank 201 with the lowest side concentration value, the sleeve 703 then drives the detection plate 3 to move downward along the reciprocating screw 7 via the mounting base 4, so that the floor paint layer 303 at the bottom of the detection plate 3 comes into contact with the detection solution in the detection tank 201. The detection plate 3 continues to rotate around the protective shell 1 in the detection tank 201. As the reciprocating screw 7 continues to rotate, after the sleeve 703 moves to the bottom of the reciprocating screw 7, it begins to drive the detection plate 3 upward via the mounting base 4. During the upward movement, the detection plate 3 crosses two adjacent detection tanks. The separator 10 between the test tanks 201, and then the sleeve 703 moves up to the upper end of the reciprocating screw 7 and then drives the test plate 3 to move down again through the mounting seat 4. During the rotation, the test plate 3 moves to the upper part of the second test tank 201 and continues to move down, so that the floor paint layer 303 at the bottom of the test plate 3 is tested in a test solution with a higher concentration. This allows the test plate 3 to enter the test tanks 201 with an increasingly higher concentration one by one for testing, which effectively improves the efficiency of floor paint anti-corrosion testing and the accuracy of the test results.

[0028] Example 3: Reference Figure 8 and Figure 9 A floor coating anti-corrosion performance testing device, based on embodiment 2, further includes two rotating rods 8 rotatably connected between two side plates 402, each rotating rod 8 is provided with a synchronous wheel 9, a synchronous belt is provided between the two synchronous wheels 9, each rotating rod 8 is provided with a protrusion 801 that moves against the test plate 3, one of the rotating rods 8 is provided with a worm gear 802, and the bottom of the reciprocating screw 7 is provided with a worm 705 that meshes with the worm gear 802.

[0029] Specifically, when the reciprocating screw 7 rotates, the worm 705 at the bottom meshes with the worm wheel 802 on the rotating rod 8 for transmission. When the worm wheel 802 rotates, it drives the rotating rod 8 connected to it to rotate. This rotating rod 8 drives another rotating rod 8 to rotate through the synchronous pulley 9 and the synchronous belt. When the two rotating rods 8 rotate, they push the detection plate 3 placed between the two limit rods 403 through the protrusion 801, causing the detection plate 3 to swing during the rotation and detection process. On the one hand, this improves the contact effect between the floor paint layer 303 and the detection solution in the detection tank 201. On the other hand, it can shake off the detection solution that moves out of the detection tank 201 with the detection plate 3, avoiding the movement of low-concentration detection solution into the high-concentration detection tank 201, which would reduce the pH of the high-concentration detection solution and affect the accuracy of the test results for the corrosion resistance of the floor paint.

[0030] Example 4: Reference Figure 7 , Figure 8 and Figure 9 A floor coating anti-corrosion performance testing device, based on embodiment 3, further includes a partition block 10 between two adjacent test tanks 201, and a guide slope 1001 is provided on the partition block 10.

[0031] Specifically, by creating a guide slope 1001 on the top of the partition block 10 between the two detection tanks 201, the protrusion 801 can push the detection plate 3. The detection solution attached to the detection plate 3 falls directly onto the guide slope 1001 and then down the slope into the detection tank 201 with a low concentration of detection solution. This avoids the detection solution falling and accumulating on the top of the partition block 10 when it moves to the top of the two detection tanks 201, making it impossible to perform anti-corrosion detection and causing waste of the detection solution.

[0032] Example 5: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 A floor coating anti-corrosion performance testing device, based on embodiment 4, further includes a pick-and-place base 5 comprising a pick-and-place shell 501 fixed to the side of the protective shell 1 and the testing base 2. Both sides of the pick-and-place shell 501 are rotatably connected to a rotating shaft 502. Each rotating shaft 502 is provided with a plurality of baffles 503 distributed equidistantly in a circle. Each baffle 503 is provided with a corrosion-resistant brush 504 on the side away from the rotating shaft 502.

[0033] Specifically, baffles 503 and corrosion-resistant brushes 504 are rotatably installed on both sides inside the pick-and-place seat 5. The corrosion-resistant brushes 504 abut against the inner wall and toothed ring of the protective shell 1, which can separate the pick-and-place seat 5 from the protective shell 1, reduce the evaporation rate of some volatile acid or alkali liquids, effectively alleviate and avoid the evaporation of acid and alkali liquids, and reduce the cost of testing the corrosion resistance of floor paint.

[0034] Example 6: Refer to Figure 1 , Figure 2 and Figure 5 A floor coating anti-corrosion performance testing device, based on embodiment 5, further includes a liquid storage tank 11 fixed inside the protective shell 1, and a solenoid valve 111 between the liquid storage tank 11 and each test tank 201. The solenoid valve 111, pH sensor 202 and camera 203 are all connected to the back-end terminal, which is also electrically connected to a display screen 12.

[0035] Specifically, as the floor paint layer 303 at the bottom of the test plate 3 moves one by one to the test tank 201, the pH sensor 202 in each test tank 201 monitors the pH value of the test solution in the tank in real time, and the camera 203 captures and records images of the floor paint layer 303 on the outside of the test plate 3, thereby testing the corrosion resistance of the floor paint layer 303. The monitoring data of the pH sensor 202 and the images captured by the camera 203 are displayed on the display screen 12. If the pH sensor 202 detects a decrease in the pH value of the test solution in the tank, it indicates that... The test solution reacts with the floor paint layer 303, and the floor paint layer 303 on the outside of the test plate 3 is corroded. The camera 203 can also monitor the corrosion of the floor paint layer 303 in real time. After the floor paint layer 303 is corroded in the test tank 201 with different pH values ​​of test solutions, its corrosion resistance can be accurately determined, which is convenient for subsequent staff to improve the anti-corrosion process of the floor paint layer 303. If the floor paint layer 303 is still not corroded when the test plate 3 is removed from the last test tank 201, it means that the anti-corrosion performance of the floor paint layer 303 meets the production requirements.

[0036] This invention also discloses a testing method for a floor coating anti-corrosion performance testing device, comprising the following steps: S1: Apply floor paint to the bottom of the vertical plate 302 of the test plate 3 to be tested. After the floor paint dries, a floor paint layer 303 is formed on the bottom of the test plate 3. Then, insert the vertical plate 302 of the test plate 3 into the two limiting rods 403 of the mounting base 4 placed in the pick-and-place seat 5. Sequentially place detection solutions with progressively increasing concentrations into each detection slot 201 on the detection seat 2, so that the concentration values ​​of the detection solutions in the detection slots 201 on both sides of the pick-up and drop seat 5 are the lowest and highest, respectively. S2: Then control the drive motor 601 to run. The output shaft of the drive motor 601 drives the drive gear 602 to rotate. The drive gear 602 meshes with the upper gear ring 603 on the inner side wall of the protective shell 1, so that the rotating seat 6 rotates around the inner side wall of the protective shell 1. When the rotating seat 6 moves, it drives the driven gear 701 at the bottom of the reciprocating screw 7 to mesh with the lower gear ring 702 on the inner side wall of the protective shell 1. The driven gear 701 revolves around the protective shell 1 while rotating on its own axis. The driven gear 701 drives the reciprocating screw 7 to rotate. When the reciprocating screw 7 rotates, the sleeve 703 connected by the outer thread moves up and down along its axial direction. The sleeve 703 drives the mounting seat 4 to rotate circumferentially while driving it to move up and down. When the detection plate 3 rotates around the protective shell 1, it first moves to the detection tank 201 with the lowest concentration value next to the pick-and-place seat 5. Then, the sleeve 703 drives the detection plate 3 to move downward along the reciprocating screw 7 through the mounting seat 4, so that the floor paint layer 303 at the bottom of the detection plate 3 comes into contact with the detection solution in the detection tank 201. The detection plate 3 continues to rotate around the protective shell 1 in the detection tank 201. As the reciprocating screw 7 continues to rotate, after the sleeve 703 moves to the bottom of the reciprocating screw 7, it begins to drive the detection plate 3 upward through the mounting seat 4. During the upward movement, the detection plate 3 passes over the partition block 10 between two adjacent detection tanks 201. Subsequently, after the sleeve 703 moves up to the upper end of the reciprocating screw 7, it drives the detection plate 3 to move down again through the mounting base 4. During the rotation, the detection plate 3 moves to the top of the second detection groove 201 and continues to move down, so that the floor paint layer 303 at the bottom of the detection plate 3 is tested in a detection solution with a higher concentration. Repeat the above steps until the test plate 3 moves to the last test tank 201, where the test solution with the highest concentration performs anti-corrosion testing on the floor paint layer 303. S3: As the floor paint layer 303 at the bottom of the test plate 3 moves one by one to the test tank 201, the pH sensor 202 in each test tank 201 monitors the pH value of the test solution in the tank in real time, and the camera 203 takes pictures and records the floor paint layer 303 on the outside of the test plate 3, thereby testing the anti-corrosion performance of the floor paint layer 303. The monitoring data of the pH sensor 202 and the images captured by the camera 203 are presented on the display screen 12. If the pH sensor 202 detects a decrease in the pH value of the test solution in the tank, it indicates that the test solution reacts with the floor paint layer 303, and the floor paint layer 303 on the outside of the test plate 3 is corroded. The camera 203 can also monitor the corrosion of the floor paint layer 303 in real time. After the floor paint layer 303 is corroded in the test tank 201 with different pH test solutions, its corrosion resistance can be accurately determined, which is convenient for subsequent staff to improve the anti-corrosion process of the floor paint layer 303. If the floor paint layer 303 is still not corroded after the test plate 3 is removed from the last test slot 201, it means that the anti-corrosion performance of the floor paint layer 303 meets the production requirements.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. A testing method for the anti-corrosion performance testing device for floor coatings as described in claim 7, characterized in that, Includes the following steps: S1: Apply floor paint to the bottom of the vertical plate (302) of the test board (3) to be tested. After the floor paint dries, a floor paint layer (303) is formed on the bottom of the test board (3). Then, insert the vertical plate (302) of the test board (3) between the two limiting rods (403) of the mounting base (4) placed in the pick-and-place seat (5). Place detection solutions with progressively increasing concentrations into each detection slot (201) on the detection seat (2) in sequence, so that the concentration values ​​of the detection solutions in the detection slots (201) on both sides of the pick-up and drop-off seat (5) are the lowest and highest, respectively; S2: Then control the drive motor (601) to run. The output shaft of the drive motor (601) drives the drive gear (602) to rotate. The drive gear (602) meshes with the upper gear ring (603) on the inner side wall of the protective shell (1), so that the rotating seat (6) rotates around the inner side wall of the protective shell (1). When the rotating seat (6) moves, it drives the driven gear (701) at the bottom of the reciprocating screw (7) to mesh with the lower gear ring (702) on the inner side wall of the protective shell (1). The driven gear (701) revolves around the protective shell (1) while rotating on its own axis. The driven gear (701) drives the reciprocating screw (7) to rotate. When the reciprocating screw (7) rotates, the sleeve (703) connected by the outer thread moves up and down along its axial direction. The sleeve (703) drives the mounting seat (4) to rotate circumferentially while driving it to move up and down. When the detection plate (3) rotates around the protective shell (1), it first moves to the top of the detection tank (201) with the lowest concentration value next to the pick-and-place seat (5). Then, the sleeve (703) drives the detection plate (3) to move down along the reciprocating screw (7) axially through the mounting seat (4), so that the floor paint layer (303) at the bottom of the detection plate (3) comes into contact with the detection solution in the detection tank (201). The detection plate (3) continues to rotate around the protective shell (1) in the detection tank (201). As the reciprocating screw (7) continues to rotate, the sleeve (703) starts to drive the detection plate (3) to move up through the mounting seat (4) after moving to the bottom of the reciprocating screw (7). During the upward movement, the detection plate (3) passes over the partition block (10) between two adjacent detection tanks (201). Subsequently, after the sleeve (703) moves up to the upper end of the reciprocating screw (7), it drives the detection plate (3) to move down again through the mounting seat (4). During the rotation, the detection plate (3) moves to the top of the second detection groove (201) and continues to move down, so that the floor paint layer (303) at the bottom of the detection plate (3) is detected in a detection solution with a higher concentration. Repeat the above steps until the test plate (3) moves to the last test tank (201) and the test solution with the highest concentration is used to test the corrosion resistance of the floor paint layer (303); S3: As the floor paint layer (303) at the bottom of the test plate (3) moves to the test tank (201) one by one, the pH sensor (202) in each test tank (201) monitors the pH value of the test solution in the tank in real time, and the camera (203) takes pictures and records the floor paint layer (303) on the outside of the test plate (3), thereby testing the anti-corrosion performance of the floor paint layer (303). The monitoring data of the pH sensor (202) and the images captured by the camera (203) are presented on the display screen (12). If the pH sensor (202) detects a decrease in the pH value of the test solution in the tank, it indicates that the test solution reacts with the floor paint layer (303), and the floor paint layer (303) on the outside of the test plate (3) is corroded. The camera (203) can also monitor the corrosion of the floor paint layer (303) in real time. After the floor paint layer (303) is corroded in the test tank (201) with different pH test solutions, its corrosion resistance can be accurately determined, which is convenient for subsequent staff to improve the anti-corrosion process of the floor paint layer (303). If the floor paint layer (303) is still not corroded after the test plate (3) is removed from the last test slot (201), it means that the anti-corrosion performance of the floor paint layer (303) meets the production requirements.
