Description

Technical Field

[0001] This utility model relates to the field of ceramic tile testing, and in particular to an online testing device for the elastic modulus of ceramic tiles. Background Technology

[0002] The modulus of elasticity, as an important property of a material, is determined by its inherent material properties. In the production and application of ceramic tiles, the modulus of elasticity is also a crucial indicator. Testing the modulus of elasticity is significant for monitoring product performance and ensuring it meets the requirements of various usage scenarios.

[0003] Traditional methods for testing the elastic modulus of ceramic tiles are mainly divided into two categories: static methods and dynamic methods. Static methods, such as the three-point bending method and compression method, measure the stress and strain of the material under stress and calculate the elastic modulus based on Hooke's law. The advantages are simple testing principles and relatively easy operation. However, the test sample generally needs to be cut and processed into a specific shape to facilitate the calculation of cross-sectional area and other data. Furthermore, factors such as loading rate and loading time have a significant impact on the results, resulting in relatively large dispersion of the test results. Multiple measurements and averaging are needed to improve accuracy. Static methods are more often used for sampling inspection and lack the feasibility of online, continuous testing of every single product.

[0004] Dynamic methods involve applying dynamic excitation to ceramic materials to induce vibration, measuring parameters such as the material's natural frequency and mode shape during vibration, and calculating the elastic modulus based on the material's vibration theory. Examples include the ultrasonic pulse method, which utilizes the propagation characteristics of ultrasound in ceramic materials, measuring the propagation speed of ultrasound waves, and calculating the elastic modulus based on the material's density and the propagation speed of ultrasound waves; and the resonance method, which uses an excitation device to induce resonance in the ceramic sample, measuring the resonant frequency of the sample, and calculating the elastic modulus based on parameters such as the sample's size, shape, and mass. Dynamic methods offer fast testing speeds, minimal damage to the sample, and results less affected by environmental factors, resulting in higher accuracy, especially suitable for measuring the elastic modulus of ceramic materials at high temperatures. The detection of the sample's resonant frequency is generally achieved through spectral analysis of the collected vibration sound or by using adhesive vibration sensors. However, sound acquisition methods are not suitable for the noisy environments of ceramic tile production lines, while adhesive sensor methods are not suitable for continuous, online testing of products on the production line.

[0005] Therefore, existing technologies have shortcomings and need to be improved and developed. Utility Model Content

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0050] This application provides an online testing device for the elastic modulus of ceramic tiles, which makes the measurement of the elastic modulus of ceramic tiles faster and more convenient, realizes continuous elastic modulus testing of ceramic tiles during the production process, and the device can be adjusted quickly and conveniently to adapt to the testing of ceramic tiles of more sizes and specifications.

[0051] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides an online testing device for the elastic modulus of ceramic tiles, including: a frame 100, and a conveying mechanism 200, a lifting mechanism 300, a tile measuring mechanism 400, a striking mechanism 500, and a distance measuring mechanism 600 disposed on the frame 100. The conveying mechanism 200 is used to receive ceramic tiles 10 from the production line. The lifting mechanism 300 is located below the conveying mechanism 200 and is used to lift and detach the ceramic tiles 10 from the conveying mechanism 200, and measure the mass of the ceramic tiles 10. The tile measuring mechanism 400 is used to measure the volume parameters of the ceramic tiles 10. The striking mechanism 500 is disposed on the frame 100 and is used to strike the ceramic tiles 10 lifted and detached by the lifting mechanism 300. The ranging mechanism 600 is provided with a first ranging sensor 610, which is used to detect the distance change data between the first ranging sensor 610 and the ceramic tile 10 caused by the vibration of the ceramic tile 10 when the striking mechanism 500 strikes the ceramic tile 10.

[0052] This application uses a conveying mechanism 200 to receive ceramic bricks 10 from the production line and lifts the ceramic bricks 10 on the conveying mechanism 200. It uses a first distance sensor 610 to collect distance change data and can simultaneously measure the mass and volume parameters of the ceramic bricks 10. This eliminates the need to collect sound or attach sensors to the ceramic bricks 10 when testing the elastic modulus of the ceramic bricks 10. It is suitable for continuous, online testing of the elastic modulus of ceramic bricks 10 on the production line.

[0053] In the embodiments of this application, such as Figure 4 As shown, the lifting mechanism 300 includes a load cell 310, a first cylinder 320, and a rope 330. The load cell 310 is mounted on the frame 100 and located below the conveying mechanism 200. The load cell 310 is used to measure the mass of the ceramic brick 10. The first cylinder 320 is mounted on the load cell 310, with its movable rod facing upwards. At least two sets of first cylinders 320 are provided. The two ends of the rope 330 are attached to the movable rod of the first cylinder 320, and are used to lift and detach the ceramic brick 10 from the conveying mechanism 200.

[0054] Specifically, since the mass of the ceramic brick 10 is required when detecting the elastic modulus, a load cell 310 is installed on the frame 100. The other end of the load cell 310 is fixed to the cylinder body of the first cylinder 320 via a plate. At least two sets of the first cylinder 320 are provided, i.e., four cylinders in total. At least two ropes 330 are provided, with both ends of the ropes 330 attached to the movable rod of the first cylinder 320. When the first cylinder 320 operates, the movable rod moves upward, the ropes 330 contact the bottom of the ceramic brick 10, and lift the ceramic brick 10, separating it from the conveying mechanism 200. This allows for the measurement of the mass and volume parameters of the ceramic brick 10, as well as the distance change data between the first distance sensor 610 and the ceramic brick 10 caused by the vibration of the ceramic brick 10, thereby achieving the elastic modulus detection.

[0055] In this embodiment, the weighing sensor 310 is integrated into the lifting mechanism 300, located below the conveying mechanism 200. When the ceramic brick 10 is conveyed to the corresponding position, the lifting mechanism 300 can directly lift it. At this time, the weighing sensor 310 can simultaneously measure the mass of the ceramic brick 10, thus eliminating the need for additional mass measurement equipment and complex transfer processes. This conveniently completes mass measurement while lifting the ceramic brick 10 away from the conveying mechanism 200, simplifying the testing process and improving measurement efficiency. Furthermore, during the elastic modulus test of the ceramic brick 10, combining the weighing sensor 310 with the lifting mechanism 300 allows mass data to be acquired in the same testing stage as other data required for the elastic modulus, facilitating data integration and analysis and providing a foundation for accurate calculation of the subsequent elastic modulus.

[0056] In this embodiment, at least two sets of first cylinders 320 are provided, thereby increasing stability and balance during the lifting process. When the movable rods of the first cylinders 320 move upward simultaneously, multiple points of action apply lifting force to the ceramic brick 10 together. Compared with a single first cylinder 320 design, the weight of the ceramic brick 10 can be distributed more evenly, reducing problems such as tilting and swaying of the ceramic brick 10 caused by uneven force, ensuring that the ceramic brick 10 remains stable during the lifting process, and providing stable test conditions for subsequent elastic modulus testing.

[0057] In this embodiment, the two ends of the rope 330 are disposed on the movable rod of the first cylinder 320. The flexibility of the rope 330 protects the ceramic tile 10 from damage when it is struck.

[0058] In this embodiment, the weighing sensor 310, the first cylinder 320, and other components are integrated into the lifting mechanism 300 and uniformly set below the conveying mechanism 200 on the frame 100. This makes full use of the vertical space of the device, making the structure of the entire testing device more compact, reducing the footprint of the device, and allowing for more flexible installation and layout on the production line to adapt to different production environments.

[0059] Therefore, the embodiments of this application enable the ceramic tile 10 to smoothly complete the process from conveying, lifting, to testing on the production line. After the conveying mechanism 200 conveys the ceramic tile 10 to the designated position, the lifting mechanism 300 immediately operates to lift and support the ceramic tile 10 for subsequent testing. After the test is completed, the ceramic tile 10 can be quickly returned to the conveying mechanism 200 to continue the production process. This continuous testing process improves production efficiency and meets the needs of online testing of the elastic modulus during the large-scale production of ceramic tiles 10.

[0060] In one embodiment of this application, a support plate 340 is fixedly connected to the movable rod of the first cylinder 320. A rope winding member 341 is provided on the support plate 340, and both ends of the rope 330 are fixed to the rope winding members 341 of the two corresponding first cylinders 320. The support plate 340 is also provided with a retaining groove, which is used to retain and fix the rope 330 fixed on the rope winding member 341.

[0061] Specifically, the rope winding member 341 can be a stud for securing both ends of the rope 330. To further secure the rope 330, the support plate 340 also has a retaining groove, allowing the rope 330 to pass through the retaining groove and be fixed to the rope winding member 341 on the other side. In one specific embodiment, each support plate 340 has only one stud, two studs form a group, and a rope 330 is strung between each group of studs.

[0062] In this embodiment, by fixing a support plate 340 to the movable rod and providing a rope winding component 341 and a clamping groove on the support plate 340, the stability of the rope 330 is improved, thereby making the lifted ceramic brick 10 more stable and ultimately improving the accuracy of the elastic modulus test of the ceramic brick 10.

[0063] In this embodiment, the lifting mechanism 300 further includes at least two parallel linear sliding guide rails 350 and a plurality of sliding plates 360. The linear sliding guide rails 350 are disposed on the frame 100; the sliding plates 360 are disposed on the linear sliding guide rails 350, and the weighing sensor 310 is disposed on the sliding plate 360.

[0064] Specifically, the linear sliding guide rail 350 is mounted on the longitudinal beam of the frame 100 below the conveying mechanism 200. The lifting mechanism 300 is also equipped with a sliding plate 360 ​​fixedly connected to the slider of the linear sliding guide rail 350, and a load cell 310 is mounted on the sliding plate 360. The sliding plate 360 ​​can slide on the linear sliding guide rail 350, thereby adjusting the spacing between the ropes 330, which enables the lifting and rigging of ceramic tiles 10 of different sizes.

[0065] In this embodiment of the application, the linear sliding guide rail 350 includes a first linear sliding guide rail 350 and a second linear sliding guide rail 350 arranged in parallel; a first sliding plate 360 ​​and a second sliding plate 360 ​​are provided on the first linear sliding guide rail 350, and a third sliding plate 360 ​​and a fourth sliding plate 360 ​​are provided on the second linear sliding guide rail 350; a connecting member 370 is provided between the first sliding plate 360 ​​and the third sliding plate 360 ​​and between the second sliding plate 360 ​​and the fourth sliding plate 360.

[0066] Specifically, each linear sliding guide rail 350 is equipped with two sets of sliding plates 360, which are fixedly connected to the sliding plate 360 ​​on another sliding guide rail via connectors 370. Each set of studs and support plates 340 is connected to another parallel stud and support plate 340 by ropes 330. In this way, the two sets of ropes 330 arranged in parallel for lifting can lift the ceramic bricks 10 on the conveying mechanism 200.

[0067] In this embodiment, two linear sliding guide rails 350 are arranged in parallel and interconnected by a sliding plate 360 ​​and a connecting member 370. During movement, each sliding plate 360 ​​slides on the guide rail. Due to the parallelism of the guide rail and the constraint of the connecting member 370, the straightness of the moving parts in the horizontal direction can be effectively guaranteed, reducing offset and swaying during movement. That is, the straightness and stability of the rope 330 are guaranteed, thereby ensuring the stability of the ceramic tile 10 when it is lifted.

[0068] In one embodiment of this application, such as Figure 5 As shown, the striking mechanism 500 includes:

[0069] The first bracket 510 is mounted on the frame;

[0070] The third linear sliding guide rail 520 is disposed on the first bracket 510, and the third linear sliding guide rail 520 is located above the lifting mechanism 300;

[0071] The fifth slide plate 530 is mounted on the third linear sliding guide rail 520;

[0072] The second cylinder 540 is mounted on the fifth slide plate 530, and the movable rod of the second cylinder 540 is positioned downwards;

[0073] Bearing 550 is connected to the movable rod of the second cylinder 540;

[0074] A striking component 560 is disposed below the second cylinder 540. The striking component 560 is in contact with the bearing 550. The striking component 560 is used to strike the ceramic tile 10 lifted and supported by the lifting mechanism 300 under the drive of the second cylinder 540.

[0075] In this embodiment, a second cylinder 540 is used to control the striking component 560 to strike the ceramic tile 10. At the same time, a bearing 550 is used as an intermediate component to make the control of the striking component 560 smoother.

[0076] In one embodiment of this application, the tapping component 560 includes:

[0077] A rotating plate 561 is disposed below the second cylinder 540, and the upper end surface of the rotating plate 561 is in contact with the bearing 550.

[0078] A rotating seat 562 is disposed on the fifth sliding plate 530, and the first end of the rotating plate 561 is rotatably connected to the rotating seat 562.

[0079] A spring retainer 563 is disposed on the fifth slide plate 530;

[0080] Spring 564, one end of which is fixed to the spring fixing seat 563, and the other end of which is connected to the second end of the rotating plate 561;

[0081] A striking rod 565 is movably disposed at the second end of the rotating plate 561. The striking rod 565 includes a rigid part 5651 and an elastic part 5652 connected to each other.

[0082] A striking hammer 566 is disposed at one end of the elastic part 5652 away from the rigid part 5651.

[0083] In this embodiment, a rotating plate 561 is provided, so that the movable rod of the second cylinder 540 smoothly pushes the rotating plate 561 downward around the rotating seat 562 via the bearing 550, thereby driving the striking rod 565 and the striking hammer 566 to move downward, performing a striking action on the ceramic tile 10. After the striking action is completed, the movable rod of the second cylinder 540 retracts, and the rotating plate 561 springs back to its original position under the action of the spring 564.

[0084] If the second cylinder 540 is used to directly drive the hammer 566 to the position of contacting the surface of the ceramic tile 10 to complete the striking action, then even if the second cylinder 540 can quickly retract the movable rod, the hammer 566 will still remain on the surface of the ceramic tile 10 for a certain period of time. The longer the contact time between the ceramic tile 10 and the hammer 566, the more likely it is to affect the vibration of the ceramic tile 10, thereby affecting the accuracy of data acquisition. Therefore, the striking rod 565 of this application is provided with an elastic part 5652, which allows the second cylinder 540 to push the rotating plate 561 to rotate downward around the rotating seat 562 to a predetermined position. At this predetermined position, the hammer 566 maintains a certain distance from the ceramic tile 10. At this time, the second cylinder 540 stops pushing. Due to the elasticity of the elastic part 5652, the hammer 566 continues to move downward under the action of inertia. After striking the ceramic tile 10, it quickly leaves the surface of the ceramic tile 10 under the action of the elasticity. This solves the problem of the long contact time between the ceramic tile 10 and the hammer 566, and improves the accuracy of data acquisition.

[0085] In addition, an adjustment hole is provided at the second end of the rotating plate 561, and the striking rod 565 is disposed in the adjustment hole. The position of the striking rod 565 in the adjustment hole can be adjusted according to actual needs, thereby changing the position of the striking hammer.

[0086] In this embodiment of the application, the ranging mechanism 600 includes: a plurality of second brackets 620 movably mounted on the frame 100; at least one first ranging sensor 610 is provided, and the first ranging sensor 610 is disposed on the second bracket 620.

[0087] Specifically, the first ranging sensor 610 is a laser ranging probe. Several laser ranging probes are distributed and mounted on the second bracket 620. The second bracket 620 can be flexibly adjusted and fixed on the frame 100. The laser ranging probes can also be flexibly adjusted and fixed on the second bracket 620, so that they can adapt to the testing of ceramic tiles 10 of different sizes, and at the same time measure the distance at different positions of the ceramic tiles 10 as needed.

[0088] In one embodiment of this application, the conveying mechanism 200 is configured as a conveying roller table; the volume parameters include the ceramic tile length, ceramic tile width, and ceramic tile thickness; the ceramic tile measuring mechanism includes a camera and a second distance sensor mounted on the frame, the camera being used to measure the ceramic tile length and ceramic tile width, and the second distance sensor being used to measure the ceramic tile thickness.

[0089] Specifically, the conveyor roller table consists of multiple parallel rollers. The ceramic brick 10 is placed on the rollers, and the rollers rotate synchronously through a motor or other drive device, thereby driving the ceramic brick 10 to move smoothly. This conveying method provides continuous and stable power, making it less prone to slippage or stagnation during the conveying process, thus ensuring high efficiency. Furthermore, there are certain gaps between the rollers of the conveyor roller table, allowing the rope 330 to lift and support the ceramic brick 10 through these gaps.

[0090] This application utilizes a camera to capture images of ceramic tiles, then identifies the length and width of the ceramic tiles from these images, and uses a second ranging sensor to measure the thickness of the ceramic tiles. The second ranging sensor can be used independently or shared with the first ranging sensor.

[0091] When measuring the thickness of a ceramic tile using a second distance sensor, the sensor is first installed at a predetermined position, and the distance h1 between the sensor and the conveyor roller table is calibrated. When the ceramic tile to be measured is conveyed onto the roller table, the distance h2 between the sensor and the upper surface of the tile is measured. The thickness of the tile is then the difference between h1 and h2. However, since the upper surface of the conveyor roller table is not flat, precise calibration is not possible. Therefore, this application uses a ceramic tile of known thickness for calibration. For example, if the thickness of the tile to be calibrated is h3, the distance h4 between the sensor and the upper surface of the tile is measured. The distance between the sensor and the roller table is then h3 + h4. The calibrated distance h3 + h4 is saved. When the tile to be measured is conveyed onto the roller table, the distance h5 between the sensor and the upper surface is measured. The thickness of the tile is then h3 + h4 - h5.

[0092] The elastic modulus of the tested ceramic tile can be calculated using the elastic modulus calculation formula in the industry standard JC / T 2172-2013 for testing the elastic modulus of fine ceramics.

[0093]

[0094] Where E is the dynamic elastic modulus of the ceramic tile, m is the mass of the ceramic tile, b is the width of the ceramic tile, L is the length of the ceramic tile, t is the thickness of the ceramic tile, and f is the bending response frequency, which is the natural frequency of the first-order vibration of the ceramic tile 10 measured by the online testing device for the elastic modulus of the ceramic tile. The natural frequency is obtained by performing a Fourier transform on the distance change data.

[0095] It should be noted that when using the above calculation method, the length of the ceramic tile must be greater than 40mm, and the length-to-thickness ratio must be greater than 40. Although the standard calculation method does not specify the aspect ratio of the tile in detail, according to experimental and simulation results, square tiles do not have a bending response frequency. Therefore, this calculation method cannot be directly applied to the calculation of the elastic modulus of square tiles. The dimensional parameters of the ceramic tiles and the bending response frequency results obtained from the tests are shown in Table 1.

[0101] This application embodiment integrates the ceramic tile measuring mechanism 400 into the online testing device for the elastic modulus of ceramic tiles, enabling the device to simultaneously detect all parameters required for elastic modulus calculation, thereby improving the efficiency of online testing.

[0102] The online elastic modulus testing device for ceramic tiles provided in this application makes the measurement of the elastic modulus of ceramic tiles 10 faster and more convenient, realizing continuous elastic modulus testing of ceramic tiles 10 during the production process; furthermore, the online elastic modulus testing device for ceramic tiles can be adjusted in a relatively quick and convenient way to adapt to the testing of more sizes and specifications of ceramic tiles 10, thereby improving the quality monitoring of ceramic tile 10 products, the stability of production, and reducing the defect rate.

[0103] The working principle of the online testing device for the elastic modulus of ceramic tiles in this application embodiment includes: a conveying mechanism 200 receiving ceramic tiles 10 from the production line; a lifting mechanism 300 lifting and detaching the ceramic tiles 10 from the conveying mechanism 200, and measuring the mass of the ceramic tiles 10; a tile measuring mechanism 400 measuring the volume parameters of the ceramic tiles 10; a striking mechanism 500 striking the ceramic tiles 10 lifted and detached by the lifting mechanism 300; a distance measuring mechanism 600 using a first distance measuring sensor 610 to detect the distance change data from the first distance measuring sensor 610 to the ceramic tiles 10 caused by the vibration of the ceramic tiles 10 when the striking mechanism 500 strikes the ceramic tiles 10; performing a Fourier transform on the distance change data to obtain the natural frequency of the first order vibration of the ceramic tiles 10, and calculating the elastic modulus of the ceramic tiles 10 based on the mass, volume parameters, and natural frequency of the ceramic tiles 10.

[0104] Specifically, using vibration frequency processing software, Fourier transform is performed on the distance change data between the laser ranging probe and the ceramic brick 10 caused by the vibration of the ceramic brick 10 measured by the laser ranging probe to extract the natural frequency f of the ceramic brick 10, and then the elastic modulus of the ceramic brick 10 is calculated using the elastic modulus calculation formula.

[0105] After the conveying mechanism 200 transports the ceramic tile 10 to the designated position, the lifting mechanism 300 immediately operates to lift and support the ceramic tile 10 for subsequent testing. After the test is completed, the ceramic tile 10 can be quickly returned to the conveying mechanism 200 to continue the production process. This continuous testing process improves production efficiency and meets the needs of online testing of the elastic modulus during the large-scale production of ceramic tiles 10.

[0106] This utility model provides an online testing device for the elastic modulus of ceramic tiles. The device includes: a frame; a conveying mechanism disposed on the frame for receiving ceramic tiles from the production line; a lifting mechanism disposed on the frame and located below the conveying mechanism, the lifting mechanism being used to lift and detach the ceramic tiles from the conveying mechanism and measure the mass of the ceramic tiles; a tile measuring mechanism disposed on the frame for measuring the volume parameters of the ceramic tiles; a striking mechanism disposed on the frame for striking the ceramic tiles lifted by the lifting mechanism; and a distance measuring mechanism disposed on the frame, the distance measuring mechanism being equipped with a first distance measuring sensor, the first distance measuring sensor being used to detect the change in distance between the first distance measuring sensor and the ceramic tiles caused by the vibration of the ceramic tiles when the striking mechanism strikes the ceramic tiles. This application uses a conveyor mechanism to receive ceramic tiles from the production line and lift them up. It uses a distance sensor to collect distance change data and can simultaneously measure the mass and volume parameters of the ceramic tiles. This eliminates the need to collect sound or attach sensors to the ceramic tiles when testing their elastic modulus. It is suitable for continuous, online testing of the elastic modulus of ceramic tile products on the production line.

[0107] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
