Description

Technical Field

[0001] This application relates to the field of coating performance testing technology, specifically to a field testing device for coating corrosion resistance. Background Technology

[0002] A coating is a solid, continuous film obtained by applying paint in a single application. It is a thin layer of plastic applied to a substrate such as metal, fabric, or plastic for purposes such as protection, insulation, and decoration. Paints can be gaseous, liquid, or solid, and the type and state of the paint are usually determined by the substrate to be sprayed. Different types of paint are used and have different names; for example, a primer coating is called a primer layer, and a topcoat coating is called a topcoat layer.

[0003] In the coating production process, to ensure the performance and integrity of the coating, samples are usually randomly selected on-site for corrosion resistance testing. In the authorized Chinese utility model patent "Announcement No.: CN217006903U, Name: Acid Boiling Test Equipment for Corrosion Resistance of Metal Bipolar Plate Coating for Fuel Cells", an acid boiling tank is used in conjunction with a constant temperature water tank to realistically simulate the corrosion resistance test of coated bipolar plates under the operating conditions of fuel cells, resulting in more accurate test results. However, in the above application, after the test object is immersed in the test liquid, a relatively long time is required for the test liquid to fully react with the surface of the test object in order to obtain a relatively accurate test result. This is not suitable for occasions in the production site where a certain level of testing efficiency is required. Summary of the Invention

[0004] This application provides a field testing device for the corrosion resistance of coatings. By moving the test object in a corrosive liquid and making the corrosive liquid flow, the test object can be fully contacted with the corrosive liquid, thereby reducing the immersion time of the test object and having relatively high testing efficiency. It is suitable for occasions in production sites where testing efficiency is required.

Detailed Implementation

[0069] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0070] This application provides an on-site testing device for the corrosion resistance of coatings, which can be referred to in conjunction with other relevant documents. Figure 1 and Figure 3 The on-site testing device for the corrosion resistance of the coating includes a test container 3, a corrosive liquid container 2, a stirring mechanism 6, a first transmission mechanism 4, a motion conversion mechanism 5, and a second transmission mechanism 7. The corrosive liquid container 2 has a test port. The stirring mechanism 6 is disposed in the corrosive liquid container 2. The first transmission mechanism 4 is connected to the test container 3 and is equipped with a drive source 41 to drive the test container 3 to reciprocate linearly. The test container 3 is rotatably connected to the first transmission mechanism 4. The motion conversion mechanism 5 is connected between the transmission mechanism and the test container 3 to drive the test container 3 to rotate on the first transmission mechanism 4. The second transmission mechanism 7 is connected between the first transmission mechanism 4 and the stirring mechanism 6 to drive the stirring mechanism 6 to move in the corrosive liquid container 2, thereby driving the corrosive liquid in the corrosive liquid container 2 to move.

[0071] The on-site testing device for coating corrosion resistance provided in this application embodiment allows the test object container 3 to change its position in the corrosive liquid container 2 under the drive of the first transmission mechanism 4 and the motion conversion mechanism 5. This prevents the test object in the test object container 3 from being in prolonged contact with the local corrosive liquid, thus avoiding the consumption of the active ingredients in the local corrosive liquid and the resulting decrease in the corrosion rate of the test object surface. After the test object reacts with the corrosive liquid at one position in the corrosive liquid container 2, it can react with the corrosive liquid at another position under the drive of the first transmission mechanism 4, indicating that the test object can continuously contact the corrosive liquid containing a large amount of active substances. Driven by the motion conversion mechanism 5, the test object container 3 can rotate, allowing the test object inside to flip during the translation process. The agitation mechanism 6 ensures that all parts of the test object are in full contact with the corrosive liquid. This agitation ensures the corrosive liquid in the container 2 is in a flowing state, guaranteeing full contact between the test object and the corrosive liquid. It also ensures the uniformity of the corrosive liquid, preventing uneven density distribution due to localized consumption. Furthermore, the flowing corrosive liquid and the moving test object create a certain degree of mutual impact, reducing the probability of a protective film forming on the surface of the test object due to corrosion. This ensures the corrosive liquid has a good corrosive effect on the test object, improving the detection efficiency and accuracy of the corrosion resistance test results. This method is suitable for production sites where high detection efficiency is required.

[0072] The on-site testing device for coating corrosion resistance provided in this application embodiment has a motion conversion mechanism 5 and a second transmission mechanism 7 connected to a first transmission mechanism 4. The linear reciprocating motion of the first transmission mechanism 4 enables the test container 3 to rotate and the stirring mechanism 6 to move in the corrosive liquid container 2. This means that the rotational motion generated by the motion conversion mechanism 5 and the motion generated by the second transmission mechanism 7 are based on the linear reciprocating motion of the first transmission mechanism 4. Only a drive source 41 needs to be configured for the first transmission mechanism 4, reducing the number of drive sources 41 used. At the same time, the second transmission mechanism 7, the motion conversion mechanism 5 and the first transmission mechanism 4 form a transmission cooperation through a mechanical structure, meaning that after the first transmission mechanism 4 moves, the second transmission mechanism 7 and the motion conversion mechanism 5 will definitely move synchronously. The test container 3 and the stirring mechanism 6 have high motion synchronization, thereby ensuring a good contact effect between the test object and the corrosive liquid.

[0073] In this embodiment, the motion synchronization refers to the synchronization of the motion states of the test container 3 and the stirring mechanism 6, that is, when the test container 3 moves, the stirring mechanism 6 moves synchronously, rather than implying that the motion frequency, speed and other parameters of the test container 3 and the stirring mechanism 6 are specifically related.

[0074] In this embodiment, the test sample container 3 is used to fill the test sample. The test sample container 3 can be constructed as a cylindrical body. The test sample container 3 is provided with a liquid inlet hole so that the corrosive liquid can enter the test sample container 3 and come into contact with the test sample to undergo a chemical reaction. The test sample container 3 rotates around its own axis to avoid causing excessive disturbance to the corrosive liquid. In other embodiments, depending on the specific shape of the test sample, the test sample container 3 can be constructed into other shapes such as square, spherical, polygonal prism, frustum, etc., and the test sample container 3 can also be constructed into a combination of various shapes.

[0075] In this embodiment, the corrosive liquid container 2 can be constructed as a square groove, with its opening serving as a detection port, allowing the test object container 3 to move within the detection port. In other embodiments, the corrosive liquid container 2 can be constructed in shapes such as spheres, pyramids, polygonal prisms, and frustums, and can also be constructed as a combination of various shapes; the detection port can also be constructed in shapes such as circles, triangles, and polygons.

[0076] In some alternative embodiments, see [reference]. Figure 3The first transmission mechanism 4 may specifically include a fixed frame, a first transmission component, and a second transmission component 42. The drive source 41 is connected to the fixed frame and may be a linear drive source or a rotational drive source. The first transmission component is movably connected to the fixed frame and is driven by the drive source 41, so that the first transmission component can move on the fixed frame under the drive of the drive source 41. The second transmission component 42 is driven by the first transmission component and is rotatably connected to the container 3 to be tested, so that under the action of transmission, when the first transmission component moves, it can drive the second transmission component 42 to move, and the second transmission component 42 drives the container 3 to move.

[0077] In actual implementation, the first transmission component is configured as a ball screw and the second transmission component 42 is configured as a ball nut to ensure good transmission accuracy between the two components. A guide rod 46, arranged parallel to the first transmission component, is connected to the fixed frame, and the second transmission component 42 has a guide hole adapted to the guide rod 46, thereby ensuring accurate movement direction of the second transmission component 42. Correspondingly, the drive source 41 is configured as a rotation drive source; by controlling the rotation direction of the drive source 41, the linear reciprocating motion of the second transmission component 42 can be achieved. In other embodiments, the first transmission component and the second transmission component 42 can be configured as a rocker arm and a slider, respectively, with the drive source 41 engaging in transmission with the rocker arm.

[0078] In some optional embodiments, see also Figure 3 , Figure 4 and Figure 5 The motion conversion mechanism 5 may specifically include a first gear and rack assembly and a sprocket drive assembly.

[0079] The first gear and rack assembly is disposed between the second transmission member 42 and the fixed frame. The first gear and rack assembly includes a fixed rack 53 and a rotating gear 52. The fixed rack 53 is connected to the fixed frame. There are two fixed racks 53, which are arranged in parallel and spaced apart on both sides of the second transmission member 42. The rotating gear 52 is rotatably connected to the second transmission member 42. Specifically, an upper connecting shaft 51 is rotatably disposed on the second transmission member 42, that is, the upper connecting shaft 51 can rotate around its own axis on the second transmission member 42. There are two upper connecting shafts 51. The two rotating gears 52 are coaxially connected to the two upper connecting shafts 51 respectively so that the rotating gears 52 can rotate synchronously with the upper connecting shafts 51.

[0080] The sprocket drive assembly is configured between the gear and rack assembly and the test container 3. The first sprocket in the sprocket drive assembly is driven by the gear and rack assembly to rotate synchronously with the gear. Specifically, the two first sprockets are coaxially connected to the two upper connecting shafts 51 to rotate synchronously with the upper connecting shafts 51. The second sprocket is connected to the test container 3 to drive the test container 3 to rotate. The test container 3 has two lower connecting shafts 54 coaxially arranged at both ends of its axial direction. The second sprocket is connected to the lower connecting shafts 54. The first sprocket and the second sprocket are connected by a drive chain 56.

[0081] When the second transmission component 42 translates on the first transmission component, the rotating gear 52 and the fixed rack 53 move relative to each other, causing the rotating gear 52 to rotate. The rotating gear 52 rotates synchronously with the upper connecting shaft 51 and the first sprocket. Under the transmission action of the transmission chain 56, the second sprocket rotates under the drive of the first sprocket. The first sprocket rotates synchronously with the lower connecting shaft 54. Since the test container 3 is rotatably connected to the first transmission mechanism 4, the test container 3 can rotate. When the test container 3 rotates, the test object inside can be flipped over to fully contact the corrosive liquid.

[0082] In some alternative embodiments, see [reference]. Figure 3 The test container 3 is connected to the first transmission mechanism 4 via the connecting column 43, so that there can be a large gap between the test container 3 and the first transmission mechanism 4, which facilitates the test container 3 to enter the corrosive liquid container 2 and avoids interference between the first transmission mechanism 4 and the detection port when the test container 3 enters the corrosive liquid container 2; wherein, an annular track 45 is provided on the outer wall of the test container 3, and a limiting slider 44 adapted to the annular track 45 is provided on the connecting column 43.

[0083] In some optional embodiments, the number of connecting posts 43 is configured to be multiple, and the number of annular tracks 45 is configured to correspond to the number of connecting posts 43, so that the test container 3 can rotate more smoothly on the connecting posts 43; wherein, a reinforcing frame 47 is connected between two adjacent connecting posts 43 to ensure structural strength and prevent each connecting post 43 from shaking and hindering the rotation of the test container 3 on the connecting posts 43.

[0084] In some optional embodiments, the second transmission mechanism 7 is configured as a motion conversion mechanism 5, that is, the second transmission mechanism 7 can convert the linear motion of the first transmission mechanism 4 into other motions such as rotational motion. When the stirring mechanism 6 rotates under the drive of the second transmission mechanism 7, it can achieve a better stirring effect on the corrosive liquid, thereby ensuring that the corrosive liquid has good fluidity.

[0085] In some optional embodiments, see also Figure 2 , Figure 3 and Figure 7 The second transmission mechanism 7 may specifically include a second gear and rack assembly; wherein the second gear and rack assembly includes a movable rack 72 and an auxiliary gear 73 that can mesh with each other, the movable rack 72 is connected to the first transmission mechanism 4, and the auxiliary gear 73 is connected to the agitation mechanism 6; in actual implementation, the movable rack 72 can be connected to the connecting column 43 through the connecting member 71, so that the movable rack 72 can follow the second transmission member 42 to make linear movements, and the movable rack 72 can drive the auxiliary gear 73 to rotate during the linear movement, so that the auxiliary gear 73 can drive the agitation mechanism 6 to rotate in the corrosive liquid container 2.

[0086] In some optional embodiments, the lower connecting shaft 54 ​​in the test container 3 can be rotatably connected to the connector 71. The connector 71 can serve as the main load-bearing component of the test container 3, thereby reducing the contact pressure between the connecting column 43 and the annular track 45 on the test container 3 and ensuring the smooth rotation of the test container 3.

[0087] In some alternative embodiments, see [reference]. Figure 3 The stirring mechanism 6 may specifically include a rotating shaft 61 and a stirring paddle 62. The rotating shaft 61 is rotatably connected to the corrosive liquid container 2 and connected to the second transmission mechanism 7 so that it rotates around its own axis under the drive of the second transmission mechanism 7. Specifically, the rotating shaft 61 is coaxially connected to the auxiliary gear 73 in the second transmission mechanism 7 so that it rotates synchronously with the gear. The stirring paddle 62 is connected to the rotating shaft 61 so that when the rotating shaft 61 is driven to rotate by the auxiliary gear 73, the stirring paddle 62 can stir the corrosive liquid.

[0088] In some alternative embodiments, the number of agitation mechanisms 6 can be configured to be multiple, with multiple agitation mechanisms 6 arranged in parallel at intervals. Each agitation mechanism 6 has an auxiliary gear 73 coaxially connected to its connecting shaft, and all auxiliary gears 73 mesh with the moving rack 72.

[0089] In some optional embodiments, the number of agitator blades 62 is configured to be multiple, and the multiple agitator blades 62 are evenly distributed along the circumference of the rotation shaft 61. The arrangement of multiple agitator blades 62 can achieve a better agitation effect on the corrosive liquid. The agitator blades 62 can be divided into two groups, and the two groups of agitator blades 62 are respectively arranged at both ends of the axial direction of the connecting shaft. Each group has multiple agitator blades 62, and each group of agitator blades 62 is evenly distributed along the circumference of the connecting shaft.

[0090] In some optional embodiments, a contact brush 63 is also included, which is connected to the rotating shaft 61. The contact brush 63 is configured to sweep the etchant towards the test container 3, allowing the etchant to enter the test container 3 more quickly, thereby enabling the etchant to make full contact with the test object.

[0091] In some optional embodiments, a lifting mechanism 9 is also included. The lifting mechanism 9 is connected to the corrosive liquid container 2 to move the corrosive liquid container 2 so that the test container 3 can enter the corrosive liquid container 2 through the detection port. The lifting mechanism 9 facilitates the entry and exit of the test container 3 into the corrosive liquid without the need for other tools, and can reduce the probability of the corrosive liquid being contaminated.

[0092] In some alternative embodiments, see further. Figure 3 The lifting mechanism 9 specifically includes adjusting columns 94, sliding plates 93, double-threaded rods 92, and a lifting power source 91. One end of each of the two adjusting columns 94 can be rotatably connected to the corrosive liquid container 2 via a rotating frame 95. The rotating frame 95 can be an existing hinge. A lifting plate 96 can be installed on the corrosive liquid container 2, and the corrosive liquid container 2 is rotatably connected to the two adjusting columns 94 via the lifting plate 96 for easy replacement. The two sliding plates 93 can be rotatably connected to the other end of each of the two adjusting columns 94 via the rotating frame 95. The two sliding plates 93 have threaded mating holes with opposite rotation directions. The double-threaded rod 92 mates with the threaded holes of the two sliding plates 93. The lifting power source 91 is connected to the double-threaded rod 92 to drive its rotation. When the double-threaded rod 92 rotates, the two sliding plates 93 can move away from or closer to each other, thereby changing the length direction of the two connecting columns 43, and thus changing the distance between the lifting plate 96 and the double-threaded rod 92.

[0093] In some optional embodiments, multiple adjusting columns 94 can be provided between the sliding plate 93 and the lifting plate 96. The multiple adjusting columns 94 are arranged in parallel and spaced apart. A positioning column 97 is movably passed through the sliding plate 93. The positioning column 97 can be connected to other fixed structures to guide the movable plate, that is, the length direction of the positioning column 97 is parallel to the length direction of the double-threaded rod 92.

[0094] In some optional embodiments, a support frame 1 is also included, with a first transmission mechanism 4 connected to the support frame 1, wherein the support frame 1 is equipped with wheels 8. The support frame 1 facilitates the overall transfer of the device.

[0095] When the lifting mechanism 9 is configured, the support frame 1 may include a support base 11, a support column 12 and a top support part 13. The top support part is connected to the support base 11 through the support column 12. The traveling wheel 8 is connected to the support base 11. The first transmission mechanism 4 is connected to the top support part. An installation groove may be provided on the support base 11. The double-threaded rod 92 and the lifting power source 91 are provided in the installation groove. Two sliding plates 93 cooperate with the double-threaded rod 92. The positioning column 97 is movably inserted through the sliding plate 93 and fixedly connected to the groove wall of the installation groove.

[0096] In some optional embodiments, the support frame 1 is provided with an anti-slip mechanism 10, which has a movable anti-slip part that can abut against the support platform when in the movable state. In actual operation, the support platform is usually the bottom surface. By setting the anti-slip mechanism 10, unnecessary displacement of the entire device can be avoided due to vibrations generated during the operation of the first transmission mechanism 4, motion conversion mechanism 5, second transmission mechanism 7, and lifting mechanism 9.

[0097] In some alternative embodiments, see [reference]. Figure 3 and Figure 8 The anti-slip mechanism 10 specifically includes an anti-slip plate 101, a retractable airbag 102, and a storage airbag 104. The anti-slip plate 101 serves as an anti-slip component to abut against the support platform. The retractable airbag 102 is connected to the support frame 1, and the anti-slip plate 101 is connected to the retractable airbag 102. The storage airbag 104 is connected to the support frame 1, and the storage airbag 104 is also connected to the retractable airbag 102 via a connecting pipe 103. The storage airbag 104 can be connected to a gas generating device. When the gas in the storage airbag 104 interacts with the gas in the retractable airbag 102, the volume of the retractable airbag 102 increases or decreases, thereby enabling the retractable airbag 102 to move the anti-slip plate 101 closer to or further away from the support platform.

[0098] In some optional embodiments, the storage airbag 104 can be disposed in the mounting groove. In operation, when the lifting assembly raises the corrosive liquid container 2, the sliding plate 93 can compress the storage airbag 104. After being compressed, the gas inside the storage airbag 104 enters the expansion airbag 102, causing the expansion airbag 102 to expand and pull the anti-slip plate 101 closer to the support platform. Specifically, when the two sliding plates 93 are close together to raise the corrosive liquid container 2, the storage airbag 104 is located between the two sliding plates 93; when the two sliding plates 93 are far apart to raise the corrosive liquid container 2, the storage airbag 104 is located on one side of the two sliding plates 93.

[0099] In some optional embodiments, a reset assembly 105 is connected between the anti-slip part and the support frame 1 to give the anti-slip part a tendency to move away from the support platform. The reset assembly 105 enables the anti-slip part to quickly move away from the support platform, thereby facilitating the rapid transfer of the entire device.

[0100] In some alternative embodiments, see [reference]. Figure 9 and Figure 10The reset assembly 105 may specifically include a fixed housing 1051, an anti-detachment strip 1053, a follower post 1054, and an elastic element 1052. The fixed housing 1051 is connected to the support frame 1, and a sliding strip hole is provided on the fixed housing 1051. The anti-detachment strip 1053 is movably inserted into the sliding strip hole. The two ends of the follower post 1054 are respectively connected to the anti-detachment strip 1053 and the anti-slip plate 101. The elastic element 1052 is connected between the anti-detachment strip 1053 and the fixed housing 1051 so that the anti-detachment strip 1053 has a tendency to move along the length direction of the sliding strip hole. In actual implementation, the elastic element 1052 can be configured as a tension spring.
