Description

Technical Field

[0001] This invention relates to the field of testing device technology, and in particular to a testing device for the performance of conductive coatings based on different coating thicknesses. Background Technology

[0002] In the research and development and production of conductive coatings, the precise control of coating thickness and the rapid detection of its conductivity are key factors in determining product quality. Traditional conductive coating performance testing usually involves manual application, segmented curing, and manual measurement, which suffers from low efficiency, poor repeatability, and insufficient data comparability. To address this, automated testing devices are now commonly used to test the conductivity of coatings.

[0003] However, while existing automated testing devices achieve automatic coating spraying and measurement, the coating thickness adjustment is not flexible enough, making it difficult to compare multiple thicknesses in the same batch of experiments. Moreover, the separation of the curing process from the testing module leads to a longer testing cycle and lower efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a conductive coating performance testing device based on different coating thicknesses. This device solves the technical problems of insufficient thickness adjustment and low testing efficiency in existing testing devices, and has the advantages of being able to flexibly adjust the coating thickness and improve testing efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a conductive coating performance testing device based on different coating thicknesses, comprising a testing box, a cyclic testing mechanism movably installed inside the testing box, a coating spraying mechanism for controlling the coating thickness at the upper end of the testing box, and an infrared detection device for detecting the conductivity of the coating at the lower end of the testing box. The cyclic testing mechanism includes a movable support rotatably installed inside the testing box, and several testing platforms are equally spaced along the circumferential direction on the outer side of the movable support. When the movable support rotates, the multiple testing platforms will rotate synchronously. The coating spraying mechanism includes a rectangular cover plate detachably installed at the upper end of the testing box, with a clearance groove through which the rectangular cover plate is opened. A coating spray can is movably installed on the rectangular cover plate, and a coating nozzle is connected to the bottom of the coating spray can. The coating nozzle passes through the clearance groove and extends into the interior of the testing box. When the coating spray can sprays coating downward through the coating nozzle, a coating of uniform thickness is formed on the surface of the testing platform.

[0006] Preferably, a drive bracket is fixedly installed on the rectangular cover plate, and a gear assembly is movably installed on the paint spray can. The gear assembly meshes with the drive bracket. When the gear assembly rotates, it will cause the paint nozzle to move horizontally along the clearance groove through cooperation with the drive bracket. Moreover, the moving speed of the paint nozzle can be controlled by the rotation speed of the gear assembly.

[0007] Preferably, a micro motor for driving the gear assembly is fixedly installed on the rectangular cover plate. The gear assembly can rotate forward or backward under the drive of the micro motor, thereby ensuring that the paint spray can can move back and forth.

[0008] Preferably, the rectangular cover plate is symmetrically provided with limiting grooves, and the paint spray can is fixedly installed with limiting protrusions. The limiting protrusions are slidably connected with the limiting grooves, thereby ensuring that the moving direction of the paint spray can is always parallel to the clearance groove and maintaining the stability of the paint spray can.

[0009] Preferably, an infrared curing lamp for curing the coating is detachably installed on the side of the testing box. When the testing platform rotates to the side where the infrared curing lamp is located, the infrared curing lamp will quickly cure the coating.

[0010] Preferably, a drive motor for driving the movable support to rotate is fixedly installed on the testing box. During the testing operation, the movable support will rotate intermittently under the action of the drive motor.

[0011] Preferably, the side of the testing box is provided with an auxiliary cleaning mechanism, which includes a cleaning box slidably connected to the testing box. An electric telescopic rod is provided on the outside of the testing box to drive the cleaning box to move. An internal groove is provided inside the cleaning box. A scraper assembly is movably installed inside the internal groove. When the scraper assembly is located at both ends of the internal groove, it can retract into the internal groove.

[0012] Preferably, the scraper assembly includes a sliding protrusion slidably connected to the internal groove, a telescopic scraper is detachably mounted on the sliding protrusion, a cleaning soft cloth is provided on the inner wall of the cleaning box, the inside of the cleaning soft cloth is soaked with cleaning liquid, when the cleaning soft cloth comes into contact with the detection platform, it will soften the coating on the detection platform, which will help the subsequent scraping operation.

[0013] By employing the above technical solution, the present invention provides a conductive coating performance testing device based on different coating thicknesses, which has at least the following beneficial effects: 1. This invention, through the meshing transmission of gear components and drive brackets, can form a coating with uniform or adjustable thickness on the testing platform. By adjusting the rotation speed of the gear components, the moving speed of the paint spray can can be precisely controlled, thereby flexibly adjusting the coating thickness. Low-speed spraying of thick coatings and high-speed spraying of thin coatings not only improves spraying efficiency but also ensures the consistency and repeatability of coatings of different thicknesses. It is suitable for multi-batch comparative experiments and significantly improves the accuracy and efficiency of conductive coating performance testing.

[0014] 2. The present invention, through the sliding cooperation of the limiting groove and the limiting protrusion, can ensure that the paint spray can maintain stable linear motion during the movement, further enhancing the controllability of the spraying process, making the coating thickness adjustment more precise and reliable, and effectively avoiding the problem of uneven coating caused by the deviation of the spraying path.

[0015] 3. This invention, through the intermittent rotation design of the movable support, combined with the collaborative work of the paint spraying mechanism, infrared curing lamp, infrared detection equipment, and auxiliary cleaning mechanism, realizes the full automation of the coating preparation → curing → detection → cleaning process, greatly reducing manual intervention and significantly improving detection efficiency. It is especially suitable for comparative experiments on large batches of coatings of various thicknesses.

[0016] 4. This invention adopts a modular layout, with functional units such as spraying, curing, testing, and cleaning distributed along the circumference of the testing box. The workstation can be switched by rotating the movable support. This not only adapts to testing needs of different scales, but also expands the application scenarios by adding or removing functional modules. While ensuring testing stability, it also gives the equipment stronger process adaptability and functional expansion potential.

[0017] 5. By setting up an auxiliary cleaning mechanism, the present invention adopts a dual cleaning strategy of pre-softening with a cleaning cloth and precise scraping with a telescopic scraper, which can quickly and effectively remove the coating on the surface of the testing platform. Moreover, the modular scraper assembly supports quick replacement, further improving the ease of maintenance and long-term operational stability of the equipment. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 While existing automated testing devices achieve automatic coating spraying and measurement, they lack flexibility in coating thickness adjustment, making it difficult to compare multiple thicknesses within the same batch of experiments. Furthermore, the separation of the curing process from the testing module leads to prolonged testing cycles and low efficiency. To address these technical shortcomings in existing technologies, such as... Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, this embodiment proposes a conductive coating performance testing device based on different coating thicknesses, which can ensure the consistency and repeatability of coatings of different thicknesses and is suitable for multi-batch comparative experiments. The device includes a testing box 1, a circulating testing mechanism 2 is movably installed inside the testing box 1, a coating spraying mechanism 3 for controlling the coating thickness is provided at the upper end of the testing box 1, and an infrared detection device 4 for detecting the conductivity of the coating is provided at the lower end of the testing box 1.

[0022] Specifically, the paint spraying mechanism 3 includes a rectangular cover plate 301 detachably mounted on the upper end of the testing box 1. A clearance groove 302 is provided through the rectangular cover plate 301, and symmetrically arranged limiting grooves 303 are provided on the rectangular cover plate 301. A limiting protrusion is fixedly mounted on the paint spray can 304, and the limiting protrusion is slidably connected to the limiting groove 303, thereby ensuring that the moving direction of the paint spray can 304 is always parallel to the clearance groove 302, maintaining the stability of the paint spray can 304. The paint spray can 304 is movably mounted on the rectangular cover plate 301, and a drive bracket 305 is fixedly mounted on the rectangular cover plate 301. A gear assembly 306 is movably mounted on the paint spray can 304, and the gear assembly 306 meshes with the drive bracket 305. A micro motor for driving the gear assembly 306 is fixedly installed on 301. The gear assembly 306 can rotate forward or backward under the drive of the micro motor, thereby ensuring that the paint spray can 304 can move back and forth. When the gear assembly 306 rotates, it will cause the paint nozzle 307 to move horizontally along the clearance groove 302 through cooperation with the drive bracket 305. Moreover, the moving speed of the paint nozzle 307 can be controlled by the rotation speed of the gear assembly 306. The bottom of the paint spray can 304 is connected to the paint nozzle 307. The paint nozzle 307 passes through the clearance groove 302 and extends into the interior of the detection box 1. When the paint spray can 304 sprays paint downward through the paint nozzle 307, it will form a coating of uniform thickness on the surface of the detection platform 203.

[0023] As can be seen from the above, initially, the paint spray can 304 is located on one side of the clearance channel 302. When spraying paint, the gear assembly 306 will rotate under the drive of the micro motor. When the gear assembly 306 rotates, it will move the paint spray can 304 along the clearance channel 302 at a constant speed through cooperation with the drive bracket 305.

[0024] During the movement of the paint spray can 304, the paint will be sprayed downward through the paint nozzle 307, thereby forming a coating of a certain thickness on the surface of the testing platform 203, in preparation for the subsequent testing of the coating's conductivity.

[0025] Moreover, if it is necessary to adjust the coating thickness, it is only necessary to control the rotation speed of the gear assembly 306. The lower the rotation speed, the lower the movement speed of the paint spray can 304, and the thicker the coating is sprayed. The higher the rotation speed, the higher the movement speed of the paint spray can 304, and the thinner the coating is sprayed. Therefore, coatings of different thicknesses can be formed on multiple inspection platforms 203 respectively.

[0026] In this embodiment, the meshing transmission between the gear assembly 306 and the drive bracket 305 enables the formation of a uniform or adjustable thickness coating on the testing platform 203. By adjusting the rotation speed of the gear assembly 306, the moving speed of the paint spray can 304 can be precisely controlled, thereby flexibly adjusting the coating thickness. Low-speed spraying of thick coatings and high-speed spraying of thin coatings not only improves spraying efficiency but also ensures the consistency and repeatability of coatings of different thicknesses. This is suitable for multi-batch comparative experiments and significantly improves the accuracy and efficiency of conductive coating performance testing. Moreover, in this embodiment, the sliding cooperation between the limiting groove 303 and the limiting protrusion ensures that the paint spray can 304 maintains stable linear motion during movement, further enhancing the controllability of the spraying process and making the coating thickness adjustment more precise and reliable. This effectively avoids the problem of uneven coating caused by spraying path deviation.

[0027] Example 2 To automate the entire process of coating preparation, curing, testing, and cleaning, and significantly reduce manual intervention, based on Example 1, as follows... Figures 1-5 As shown, this embodiment includes a cyclic detection mechanism 2. Specifically, the cyclic detection mechanism 2 includes a movable support 201 rotatably installed inside the detection box 1. A drive motor 202 for driving the movable support 201 to rotate is fixedly installed on the detection box 1. During the detection operation, the movable support 201 will rotate intermittently under the action of the drive motor 202. Several detection platforms 203 are evenly spaced along the circumferential direction on the outer side of the movable support 201. When the movable support 201 rotates, it will cause multiple detection platforms 203 to rotate synchronously. An infrared curing lamp 204 for curing the coating is detachably installed on the side of the detection box 1. When the detection platform 203 rotates to the side where the infrared curing lamp 204 is located, the infrared curing lamp 204 will quickly cure the coating.

[0028] As can be seen from the above, during the conductivity test, the movable bracket 201 will rotate intermittently under the action of the drive motor 202. The rotation angle can be flexibly adjusted according to the number of test platforms 203. In this embodiment, four test platforms 203 rotate 90 degrees each time as an example.

[0029] Initially, the testing platform 203 is positioned below the paint spraying mechanism 3. At this time, the paint spraying mechanism 3 will automatically spray a coating of a certain thickness onto the testing platform 203. Subsequently, the movable bracket 201 will rotate 90 degrees so that the testing platform 203 faces the infrared curing lamp 204. Next, the infrared curing lamp 204 will perform a rapid curing process on the coating.

[0030] Subsequently, the cured testing platform 203 will rotate to be below the movable bracket 201 and facing the infrared detection device 4. Next, the infrared detection device 4 will first emit an infrared laser onto the coating surface, and then measure the non-contact conductivity based on the change in the intensity of the reflected light. After the measurement is completed, the movable bracket 201 will rotate 90 degrees again so that the testing platform 203 faces the auxiliary cleaning mechanism 5. Next, the auxiliary cleaning mechanism 5 will quickly clean the coating on the testing platform 203. After cleaning is completed, the testing platform 203 will rotate again to be below the paint spraying mechanism 3.

[0031] This embodiment, through the intermittent rotation design of the movable support 201, combined with the collaborative work of the paint spraying mechanism 3, infrared curing lamp 204, infrared detection equipment 4, and auxiliary cleaning mechanism 5, achieves full automation of the coating preparation → curing → detection → cleaning process, significantly reducing manual intervention and greatly improving detection efficiency. It is especially suitable for comparative experiments on large batches of coatings of various thicknesses. Moreover, this embodiment adopts a modular layout, with functional units such as spraying, curing, detection, and cleaning distributed around the circumference of the detection box 1. The rotation of the movable support 201 enables station switching, which can not only adapt to different scales of detection needs, but also expand the application scenarios by adding or removing functional modules. While ensuring detection stability, it also gives the equipment stronger process adaptability and functional expansion potential.

[0032] Example 3 In order to quickly and effectively remove the coating on the surface of the testing platform 203, based on the above embodiments, such as Figure 1 and Figure 7 As shown, in this embodiment, an auxiliary cleaning mechanism 5 is provided on the side of the testing box 1. Specifically, the auxiliary cleaning mechanism 5 includes a cleaning box 501 slidably connected to the testing box 1. An electric telescopic rod 502 is provided on the outside of the testing box 1 to drive the cleaning box 501 to move. An internal groove 503 is provided inside the cleaning box 501. A scraper assembly 504 is movably installed inside the internal groove 503. When the scraper assembly 504 is located at both ends of the internal groove 503, it can retract into the internal groove 503. The scraper assembly 504 includes a sliding protrusion slidably connected to the internal groove 503. A telescopic scraper is detachably installed on the sliding protrusion. A cleaning soft cloth is provided on the inner wall of the cleaning box 501. The cleaning soft cloth is soaked in cleaning liquid. When the cleaning soft cloth comes into contact with the testing platform 203, it will soften the coating on the testing platform 203, which will help with the subsequent scraping operation.

[0033] As can be seen from the above, when the testing platform 203 is rotated to the side where the cleaning box 501 is located after the test is completed, the cleaning box 501 will move towards the inside of the testing box 1 under the action of the electric telescopic rod 502, so that the testing platform 203 comes into contact with the cleaning cloth inside the testing box 1. Subsequently, the cleaning liquid on the cleaning cloth will quickly soften the coating on the testing platform 203.

[0034] Next, the telescopic scraper located at the end of the inner groove 503 will automatically extend outward and contact the inspection platform 203. At the same time, the sliding protrusion will move horizontally along the inner groove 503 under the action of the hydraulic rod (not shown in the figure). When the sliding protrusion moves, it will cause the telescopic scraper to move synchronously, thereby scraping off the paint on the inspection platform 203 to prepare for the next inspection.

[0035] This embodiment, by setting up an auxiliary cleaning mechanism 5, adopts a dual cleaning strategy of pre-softening with a cleaning cloth and precise scraping with a telescopic scraper, which can quickly and effectively remove the coating on the surface of the detection platform 203. Moreover, the modular scraper assembly 504 supports quick replacement, further improving the ease of maintenance and long-term operational stability of the equipment.

The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
