Description

Technical Field

[0001] This invention relates to the field of antibacterial board detection technology, specifically to an antibacterial board surface detection device based on visual recognition. Background Technology

[0002] Antibacterial boards are widely used in fields with high hygiene requirements, such as medical, food processing, and home decoration, because they have the property of inhibiting the growth of microorganisms. Their surface properties (such as durability, scratch resistance, and cleaning effect) directly affect the user experience and service life. Therefore, they must undergo strict surface testing before leaving the factory. Currently, surface testing of antibacterial boards mostly employs a combination of manual operation and single equipment, which presents the following core problems: low testing efficiency, requiring manual operation of board handling, wiping tests (such as cloth wiping simulating cleaning scenarios and eraser wiping for stain removal), and hardness testing (such as pencil marking), etc., each step requires manual switching of equipment and adjustment of board position, resulting in a fragmented process that is difficult to adapt to the needs of industrial-scale batch testing; poor testing accuracy, as it is difficult to maintain consistent force, angle, and frequency during manual wiping tests, leading to highly subjective test results for wiping effects (such as surface wear and cleaning residue); and in hardness testing, the contact angle and pressure between the pencil and the board depend on manual control, which can easily result in uneven marking depth, affecting the accuracy of hardness judgment. To address the aforementioned issues, the industry urgently needs a device that integrates antibacterial board load-bearing, transmission, multi-type wiping tests, hardness testing, and visual recognition to improve testing efficiency and accuracy and meet the standardized requirements of industrial batch testing. Based on this, the present invention proposes an antibacterial board surface testing device based on visual recognition. Summary of the Invention

Several pencils are movably inserted through the chuck, and the pencils are pressed against the second fixing screws. The pencils can fit against the upper wall of the conveyor belt body.

The other end of the locking rod is located in the top seat, and the other end of the locking rod is connected to the other end of the second spring.

[0013] The present invention proposes a visual recognition-based antibacterial board surface detection device, which, compared with traditional manual testing, has the following advantages: 1. Traditional manual testing requires manually moving the test material, switching testing tools (cloth, eraser, different types of pencils), and adjusting the testing position. The process is fragmented and time-consuming. This invention automates the operation through its main structure: the conveyor belt automatically transports the test material, and the first motor drives the turntable to rotate the test material at both ends without manual intervention. At the same time, the hardness testing structure on the left automatically replaces different types of pencils with a chuck driven by a third motor, and the wiping testing structure on the right automatically switches between the first and second wiping units (wet cloth, eraser) through a lifting component. This saves time on manual tool switching, adapts to the needs of industrial batch testing, and significantly improves testing efficiency compared to traditional manual methods.

[0014] 2. In traditional manual testing, the wiping force / frequency and the pencil marking angle / pressure are all controlled manually, which can easily lead to subjective results and poor repeatability due to differences in operation. This invention achieves standardized testing through a mechanical structure: the wet cloth is fixed to the pressure plate by the spring of the first wiping unit, and swings stably with the swing frame to ensure uniform wiping force and frequency; the hardness testing structure fixes the angle of the swing seat through the locking rod and the slot, and the second fixing screw tightens the pencil to ensure that the contact angle and pressure between the pencil and the board are constant; at the same time, the imaging judgment of the cameras at both ends avoids the error of human visual observation, and the detection accuracy and result consistency are far superior to traditional manual methods.

[0015] 3. Traditional manual testing requires transferring the test material between different testing stations (hardness testing station, wiping testing station), which is prone to bumps and damage, and cannot simultaneously correlate multiple test data. This invention integrates multiple testing functions through an integrated design: the test material is placed on the conveyor belt body at once, the left end can complete the hardness scribing test with different pencils, and the right end can complete the wet cloth wiping test; after the turntable is reversed, the fan at the left end dries the test material, and the second wiping unit automatically erases the scribing with an eraser. At the same time, the camera images both ends of the test material, and simultaneously determines the hardness (scribing residue) and durability (surface condition after wiping). There is no need to transfer the test material, which avoids the risk of damage and enables the correlation and matching of multiple test data.

[0016] 4. Traditional manual testing requires repetitive actions such as handling, wiping, and marking over extended periods, resulting in high labor intensity. Furthermore, manual contact with the substrate easily causes surface contamination, affecting test results. This invention only requires initial placement of the substrate; subsequent conveying, reversing, testing, and judgment are all automatically completed by a mechanical structure, significantly reducing manual labor intensity. Simultaneously, it minimizes direct contact between humans and the substrate, avoiding fingerprints, stains, and other contaminants, ensuring a clean testing environment, and further improving the reliability of test results.

[0017] 5. Traditional manual testing relies on manual recording of test data (such as pencil type, number of wipings, and judgment results), which is prone to omissions or errors and hinders subsequent quality traceability. This invention uses camera imaging for judgment, which can retain image data of both ends of the board before and after testing. Combined with the test parameters of the mechanical structure (such as pencil type and number of wipings), a complete test record is formed, facilitating subsequent quality traceability and problem investigation, and providing data support for quality control in the production of antibacterial boards.

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] Please see Figures 1-9 This invention provides a technical solution: a visual recognition-based antibacterial board surface detection device, comprising a main structure 1, a wiping structure, and a hardness testing structure 6. The wiping structure is fixedly mounted on the main structure 1 and swings through the main structure 1. The hardness testing structure 6 is fixedly mounted on the main structure 1 and is opposite to the wiping structure. The main structure 1 is used to support and redirect the board material, the wiping structure is used for different wiping tests, and the hardness testing structure 6 is used for surface hardness detection.

[0022] Furthermore, the main structure 1 includes a base 11, a frame 12, a first motor 13, a turntable 14, a pair of retaining edges 15, a conveyor belt body 16, and a swing assembly 17; the frame 12 is fixedly disposed above the middle of the base 11, and the frame 12 and the base 11 are supported by two pairs of pillars; the first motor 13 is fixedly disposed in the middle of the upper wall of the frame 12, and the drive end of the first motor 13 moves through the middle of the frame 12; the turntable 14 is fixedly disposed on the drive end of the first motor 13, and the turntable 14 is located on the frame 11. The upper part of the turntable 14 is rotatable. A pair of the baffles 15 are symmetrically arranged on the upper walls of the front and rear ends of the turntable 14. The conveyor belt body 16 is fixedly embedded in the middle of the turntable 14. The swing component 17 is fixedly arranged on the upper wall of the right end of the base 11. The base 11 supports the frame 12. The frame 12 assists the first motor 13. The first motor 13 drives the conveyor belt body 16 on the turntable 14 to rotate, realizing the reversal. The conveyor belt body 16 can drive the plate to move left and right. The swing component 17 drives the wiping structure to swing.

[0023] More specifically, by designing the specific assembly and workflow of each component of the main structure 1, the antibacterial plate can be automatically loaded, transported and reversed, effectively replacing the traditional manual handling and positioning operations, reducing human intervention errors, and providing a stable foundation for the collaborative work of the subsequent wiping test structure and hardness test structure 6, ensuring the efficient operation of the overall testing device.

[0024] Furthermore, the swing assembly 17 includes a first slide rail 171, a bracket 172, a housing 173, a second motor 174, and a swing frame 175; one end of the first slide rail 171 is fixedly mounted on the middle of the upper right wall of the base 11, and the first slide rail 171 is located on the right side of the frame 12; one end of the bracket 172 is fixedly mounted on the first slide rail 171, and the bracket 172 can move left and right via the first slide rail 171; the housing 173 is fixedly mounted on the other end of the bracket 172, and the housing 173... Located above the conveyor belt body 16, the second motor 174 is fixedly installed inside the housing 173, and the drive end of the second motor 174 moves through the upper wall of the housing 173. One end of the swing frame 175 is fixedly installed on the drive end of the second motor 174, and the other end of the swing frame 175 is concave. The first slide rail 171 drives the bracket 172 to move left and right, adjusting the position of the swing frame 175 relative to the conveyor belt body 16. The second motor 174 inside the housing 173 drives the swing frame 175 to swing back and forth.

[0025] More specifically, the precise assembly and automated workflow design of each component of the swing assembly 17 not only enables flexible position adjustment and stable swing drive of the wiping structure, but also works in coordination with the conveyor belt body 16 and turntable 14 of the main structure 1 to ensure the uniformity and accuracy of the antibacterial plate surface wiping test, effectively replacing the traditional manual wiping operation and improving the testing efficiency and result consistency.

[0026] Furthermore, the wiping structure includes a lifting assembly 2, a first wiping unit 3, and a second wiping unit 4; the lifting assembly 2 is fixedly mounted on the other end of the swing frame 175, the first wiping unit 3 is fixedly mounted on the lifting assembly 2, and the second wiping unit 4 is fixedly mounted on the lifting assembly 2, and the second wiping unit 4 and the first wiping unit 3 alternately rise and fall, wherein the lifting assembly 2 is used to drive the alternating rise and fall of the first wiping unit 3 and the second wiping unit 4 to realize the replacement of the test.

[0027] Furthermore, the lifting assembly 2 includes a mounting plate 21, a third motor 22, a pair of first gears 23, a pair of pulleys 24, a belt 25, a pair of second gears 26, a pair of slides 27, and a pair of swing arms 28. The mounting plate 21 is fixedly mounted on the other end of the swing frame 175, and lifting grooves 29 are provided in the middle of both the front and rear ends of the mounting plate 21. The third motor 22 is fixedly inserted through the middle of the top of the mounting plate 21, and is located between the other ends of the swing frame 175. The pair of first gears 23 are movably mounted on the right side wall of the mounting plate 21 via first shafts and are located in the middle of the bottom end of the mounting plate 21. The pair of pulleys 24 are fixedly mounted on the drive end of the third motor 22 and the first shaft of one of the first gears 23, respectively. The two ends of the belt 25 are movably fitted onto the pulleys 24. The pair of second gears 26 are movably mounted on the mounting plate 21 via second shafts. On the right side wall, the second gear 26 meshes with the first gear 23. The second shaft on the second gear 26 movably passes through the mounting plate 21. One end of each pair of slides 27 is movably embedded in the lifting groove 29. One end of each pair of swing arms 28 is fixedly mounted on the second shaft, and the swing arms 28 are located on the left side of the mounting plate 21. The other end of each pair of swing arms 28 is a rectangular frame structure, and the other end of each swing arm 28 is movably fitted onto the other end of the slide 27. The third motor 22 is started, and through the transmission of pulley 24 and belt 25, one of the first gears 23 is driven to rotate. Through the meshing transmission of the two first gears 23 and the two second gears 26, the two second gears 26 are rotated in opposite directions, thereby driving the swing arms 28 to rotate in opposite directions. One swing arm 28 flips upward and the other swing arm 28 flips downward, which can move the slide 27 up and down along the lifting groove 29.

[0028] More specifically, by precisely selecting and assembling each transmission component of the lifting assembly 2, and combining it with the precise control of the third motor 22, the stable alternating lifting of the two wiping units is achieved, ensuring that the contact state between the wiping component and the antibacterial plate surface is consistent during the wiping test, effectively improving the accuracy and repeatability of the wiping test, while providing flexible lifting and adjustment capabilities for the wiping test structure to adapt to antibacterial plates of different thicknesses.

[0029] Furthermore, the first wiping unit 3 includes a first pressure frame 31, a support plate 32, a telescopic rod 33, a connecting rod 34, a first spring 35, and a pair of pressure plates 36; one end of the first pressure frame 31 is fixedly mounted on the other end of one of the slide blocks 27, the support plate 32 is fixedly mounted on the other end of the first pressure frame 31, the telescopic rod 33 movably passes through the other end of the first pressure frame 31, and the telescopic rod 33 is located above the middle of the support plate 32; the middle of the connecting rod 34 is fixedly mounted on one end of the telescopic rod 33, and the first spring 35 is movably sleeved.

By installing the cloth, the wiping effect and durability can be tested by simulating the wiping of the board.

[0030] More specifically, by optimizing the structural design and workflow of each component of the first wiping unit 3, not only can the wiping cloth be quickly installed and securely fixed, but it can also accurately simulate the wiping action in actual cleaning scenarios through the collaboration with the lifting component 2 and the swing component 17, ensuring the authenticity and accuracy of the wiping effect and durability test of the antibacterial plate surface, effectively replacing the traditional manual wiping test, and improving the standardization level and efficiency of the test.

[0031] Furthermore, the second wiping unit 4 includes a second pressure frame 41, a retaining ring 42, and several first fixing screws 43; one end of the second pressure frame 41 is fixedly mounted on the other end of another slide 27, and the retaining ring 42 is fixedly mounted on the other end of the second pressure frame 41. Several first fixing screws 43 are respectively screwed onto the front and rear side walls and the left side wall of the retaining ring 42; the retaining ring 42 is lowered by the second pressure frame 41 with the help of the slide 27, and the existing rubber can be embedded and fixed in the retaining ring 42 by the first fixing screws 43, so that the rubber can be lowered to contact the plate, thereby realizing swing wiping, which is used to fit the hardness test structure 6.

[0032] More specifically, by optimizing the structure and precisely assembling the components of the second wiping unit 4, the rubber can be quickly fixed and replaced. At the same time, through coordinated control with the lifting component 2, the swing component 17 and the hardness testing structure 6, the wiping action is ensured to precisely match the requirements of the scribing removal. This not only ensures the accuracy of the hardness test results, but also simultaneously detects the durability of the board surface, further enhancing the integrated testing capability of the device.

[0033] Furthermore, the first pressure frame 31 and the second pressure frame 41 are located opposite each other on the upper and lower sides, and both the first pressure frame 31 and the second pressure frame 41 are equipped with cameras 5 on the lower wall near one end, which are used to meet design requirements and realize industrialized visual inspection technology.

[0034] Furthermore, the hardness testing structure 6 includes a second slide rail 60, a third slide rail 61, a connecting frame 62, a fan 63, a swing base 64, a fourth motor 65, a chuck 66, several second fixing screws 67, several pencils 68, a top base 69, a second spring 70, and a locking rod 71; the second slide rail 60 is fixedly mounted on the upper left wall of the base 11, the third slide rail 61 is vertically mounted on the second slide rail 60, one end of the connecting frame 62 is fixedly mounted on the second slide rail 60, and the connecting frame 62 moves up and down via the third slide rail 61, and the fan 63 is fixedly mounted on the other end of the connecting frame 62.

Three pairs of insertion holes 8 are equidistantly arranged in the middle of the chuck 66, and several slots 8 are equidistantly arranged on the side wall of the chuck 66, with the slots 8 respectively located between the insertion holes 8. Several second fixing screws 67 are respectively screwed... A pair of pencils 68 are attached to the side wall of the chuck 66, and the second fixing screw 67 is connected to the insertion hole 8. Several pencils 68 are movably inserted through the chuck 66, and are secured by the second fixing screw 67. The pencils 68 can fit against the upper wall of the conveyor belt body 16. The top seat 69 is fixedly mounted on the left side wall of the other end of the swing seat 64. One end of the second spring 70 is fixedly mounted inside the top seat 69. One end of the locking rod 71 movably passes through the other end of the swing seat 64, and one end of the locking rod 71 can be inserted into the slot 8. The other end of the locking rod 71 is located inside the top seat 69, and the other end of the locking rod 71 is connected to the second spring 70. One end is connected; the second slide rail 60 drives the third slide rail 61 to move back and forth to adjust the position, and the third slide rail 61 drives the pencil 68 fixed on the chuck 66 to move up and down, thereby adjusting the rotation angle of the movable set of the swing seat 64, so as to adjust the angle of contact between the pencil 68 and the board. The fourth motor 65 drives the chuck 66 to rotate, thereby realizing the use of different pencils 68. By contacting the board with the pencil 68, and by using the movement of the pencil 68 and the movement of the board, the pencil 68 contacts and draws lines on the board, and then rubs with an eraser to test the hardness and observe whether a mark is left.

[0035] More specifically, through the standardized assembly and process design of the six components of the hardness testing structure, it realizes the switching of multiple types of pencils, precise angle setting, automated scribing and cleaning judgment, which not only meets the national standard testing requirements, but also forms an integrated testing process of "scribing-wiping-judgment" through collaboration with the wiping test structure, effectively replacing the traditional manual scribing and judgment, and improving testing efficiency and result accuracy.

[0036] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0037] This device uses the main structure 1 to carry, transport, and redirect the antibacterial board. The wiping and testing structure completes multi-scenario wiping tests (simulated cleaning with a wet cloth and removal by an eraser). The hardness testing structure 6 performs hardness testing by drawing lines with a pencil 68. The three structures work together and are linked with the overall control system through the visual recognition of the camera 5. This forms an integrated testing process of "feeding, transport, hardness testing, wiping, redirection, secondary testing, and judgment", replacing traditional manual operation and realizing automated and standardized testing of the surface performance of the antibacterial board.

[0038] Step 1: The main structure 1 is placed stably on the base 11, the turntable 14 is kept horizontal, the conveyor belt body 16 is stationary, and the left and right ends of the conveyor belt body 16 are respectively opposite to the hardness testing structure 6 and the first wiping unit 3; wherein the swing component 17 is located in the standby position on the right end of the base 11. Next, the wet cloth is laid flat on the lower wall of the support plate 32 of the first wiping unit 3, and the telescopic rod 33 is manually pulled upward to cause the adapter rod 34 to lift the pressure plate 36 and compress the first spring 35. This allows the two ends of the cloth to be folded back to the upper walls of the support plate 32. Then, with the help of the force of the first spring 35, the pressure plate 36 is pressed firmly onto the two ends of the cloth, thus fixing the cloth on the support plate 32. At the same time, the rubber is inserted through the retaining ring 42 in the second wiping unit 4, and the rubber is fixed by the first fixing screw 43 on the side wall of the retaining ring 42. Meanwhile, the pencil 68 used for testing is inserted through the insertion hole 8 of the chuck 66 and fixed by the second fixing screw 67, thus completing the preparatory work. Step 2: The operator places the antibacterial plate to be tested stably on the conveyor belt body 16 in the middle of the turntable 14 of the main structure 1, so that the plate is limited by the retaining edge 15 to prevent it from shifting under force during the wiping test. Then, the swing seat 64 connected in the hardness test structure 6 is flipped up and lifted, so that the end of the pencil 68 is attached to the left end of the board. According to the test requirements, the connecting frame 62 can be raised and lowered by activating the third slide rail 61, thereby adjusting the contact position and tilt angle of the pencil 68. At this point, the conveyor belt body 16 can be activated to move the plate left and right, and horizontal lines can be drawn by contacting the pencil 68. Alternatively, the second slide rail 60 can be activated to move the third slide rail 61 back and forth, thereby moving the pencil 68 to contact the plate and achieve longitudinal line drawing test. During the line drawing test, the fourth motor 65 in the swing seat 64 can be activated to drive the chuck 66 to rotate at an equal angle, thereby changing the pencil 68 in contact with the plate on the chuck 66 and enabling testing of different models and specifications of pencil 68. After the chuck 66 rotates, the second spring 70 in the top seat 69 will cause one end of the locking rod 71 to pass through the swing seat 64 and embed into the slot 8 of the chuck 66 for assisted limiting and equal angle adjustment. Step 3: Wiping test with a wet cloth on the right end. By starting the third motor 22 located on the mounting plate 21 in the lifting assembly 2, the third motor 22 drives the pulley 24, which in turn drives one of the first gears 23 to rotate via the belt 25. Since the two first gears 23 mesh with each other and the two second gears 26 mesh with the first gears 23 respectively, the four gears are connected in series, thereby causing the second gear 26 to rotate in the opposite direction. The reverse rotation of the second gear 26 will cause the swing arm 28 to flip upward and downward. The upward flip of the swing arm 28 will cause the slide 27 to move upward in the lifting groove 29, and the other end of the slide 27 will move with the swing arm 28, which will raise the first wiping unit 3 on the first pressure frame 31, while the other slide 27 will drive the second wiping unit 4 on the second pressure frame 41 to descend. According to the test requirements, the cloth on the support plate 32 is lowered first to contact the right end of the plate. The camera 5 on the first pressure frame 31 images the image, and the first slide rail 171 in the swing assembly 17 is activated to adjust the left and right feeding position of the cloth. Through the contact between the cloth and the plate, the second motor 174 in the support of the bracket 172 is activated to drive the swing frame 175 to swing back and forth, so that the cloth can contact the right end of the plate to perform the back and forth swing wiping test. Step 4: After the wiping test, the left end of the board is also relatively complete of the scribing hardness test of pencil 68. Therefore, pencil 68 can be removed from the board by manually lifting the swing base 64. Alternatively, depending on the cost requirements, an electric push rod body can be installed between the connecting frame 62 and the swing base 64 for automatic control to lift or lower pencil 68. After the pencil 68 detaches from the board, the first motor 13 is activated, which drives the turntable 14 in the main structure 1 to rotate 180 degrees, thereby changing the position of the left and right ends of the board. The wet end of the board is then placed under the fan 63 to dry. The end of the pencil 68 that marks the line is aligned with the second wiping unit 4. The second wiping unit 4 descends, bringing the eraser into contact with the board. The camera 5 on the second pressure frame 41 determines the contact position by imaging. The eraser can then be used to swing and wipe the board, thereby imaging the surface of the board after wiping. Step 5: After determining the hardness of one end of the board, turn the board over again and place the dried end of the board opposite the first wiping unit 3. The image test can then be completed by using the camera 5 on the first pressure frame 31.

[0039] Step 6: Since the chuck 66 in this solution is equidistantly set with six pencils 68, each pencil 68 is at a 60-degree angle to the other. In order to ensure that each pencil 68 passes through the chuck 66 to the same length, when installing the pencils 68, the third slide rail 61 can be started to drive the swing seat 64 to the highest position. Then, the swing seat 64 is flipped vertically downward. Then, one end of the plate is placed at the left end of the conveyor belt body 16, while the other end of the plate is suspended on the left side of the conveyor belt body 16, that is, one end of the plate is below the chuck 66. When installing the pencils 68 at this time, the pencils 68 will pass through the chuck 66 and contact the plate for limiting, thus achieving the installation of pencils 68 with equal length.
