[0002] Ceramic tiles, a widely used decoration material, occupy a crucial position in the market with their diverse styles and excellent performance. Today, in the pursuit of a high-quality living environment, the flatness of the surface of ceramic tiles, as one of the core indicators for measuring their quality, is of self-evident importance. It not only directly relates to the practical performance after the ceramic tiles are laid, such as the comfort of walking and the cleanliness of the space, but also profoundly affects the aesthetic effect and visual experience of the overall decoration. Therefore, in the production process of ceramic tiles, strict detection of the surface flatness has become an essential link.

[0003] Since the 21st century, with the rapid development of technology, the ceramic tile production industry in China has witnessed unprecedented prosperity, and the high degree of automation of the production process has become the norm in the industry. In the field of ceramic tile surface quality detection, advanced technologies such as visual detection and laser displacement sensors have been widely applied in detection equipment, greatly improving the accuracy and efficiency of detection. However, these high-end devices often come with high costs, making them more accessible to large ceramic tile production enterprises. Due to budget constraints, many small and medium-sized manufacturers have to rely on traditional manual detection methods, such as using a feeler gauge for measurement. This method is not only inefficient and difficult to meet the requirements of large-scale production, but also difficult to guarantee accuracy and consistency, which may in turn affect the market competitiveness of ceramic tile products.

[0032] Secondly, the trigger module is used to detect the feature points on the surface of the ceramic tile. When a certain feature point on the surface of the ceramic tile passes through the trigger module, an electrical signal will be triggered.

[0048] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0051] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0052] A tile surface flatness detection device includes a transmission module 1, a trigger module 2, a measurement module 3, and a data acquisition module 4. The trigger module 2, the measurement module 3, and the data acquisition module 4 are electrically connected to each other.

[0053] The tile to be measured and the trigger module 2 are placed on the transmission module 1. The trigger module 2 is located on one side of the tile to be measured. An arched mounting bracket 5 is installed above the transmission module 1, and the measurement module 3 and the data acquisition module 4 are installed on the arched mounting bracket 5.

[0054] The transmission module 1 is used to convey the tile to be measured and the trigger module 2. The trigger module 2 is used to synchronously trigger the data acquisition module 4 to collect and record the data of the corresponding surface feature points on the tile to be measured measured by the measurement module 3 according to the distance between the surface feature points of the tile to be measured. The measurement module 3 is used to measure the data of the surface feature points of the tile to be measured and send it to the data acquisition module 4. The data acquisition module 4 is used to process and display the data of the surface feature points of the tile to be measured collected, and transmit the data of the surface feature points to an external data processing module in real time.

[0055] It should be noted that according to the requirements of the national standard GB / T 3810.2-2016, there are 9 surface feature points that need to be measured on the tile surface, namely the center point of the tile surface, the 4 midpoints of the 4 sides of the tile surface, and the 4 corner points of the tile. Among them, the distance from the midpoint of the 4 sides of the tile to the corresponding side is 1 cm, and the distance from the 4 corner points to the corresponding two sides is 1 cm, as Figure 4 shown by points A - I.

[0056] As Figure 1-2 shown, the working principle of this tile surface flatness detection device is mainly based on the collaborative work of the following several modules:

[0057] First of all, the transmission module 1 is the starting point of the entire detection process and is responsible for conveying the tile to be measured along a preset path at a constant speed. At the same time, the trigger module 2 is also placed on the transmission module 1 and maintains a relatively fixed position with one side of the tile to be measured to ensure that its surface can be continuously monitored during the movement of the tile.

[0058] Secondly, the trigger module 2 is used to detect the feature points on the tile surface. When a certain feature point on the tile surface passes through the trigger module 2, an electrical signal will be triggered. This electrical signal is synchronously generated based on the distance between the surface feature points of the tile, ensuring that the data acquisition module 4 collects and records the data of the measurement points on the surface of the tile to be measured measured by the measurement module 3 at the correct position.

[0059] Then, after receiving the trigger signal sent by the trigger module 2, the data acquisition module 4 installed on the arched mounting bracket 5 immediately collects and records the measurement data of the measurement module 3. The measurement module 3 performs high-precision measurement on the feature points on the tile surface. These measurement data reflect the height or depth information of the tile surface relative to a certain reference plane.

[0060] Finally, the data acquisition module 4 processes the measurement data of the measurement module 3 collected through the built-in circuit system and software, and then transmits it in real time to the external data processing module. The algorithm built into the data processing module calculates the flatness of the ceramic tile according to the national detection specifications, including the center curvature, warpage, and edge curvature, and grades, displays, and saves the data of the ceramic tile flatness according to the standards set by the manufacturer.

[0061] In summary, through the precise synchronization of the trigger module 2, the data acquisition module 4 and the measurement module 3, and the application of high-precision sensors, this ceramic tile surface flatness detection device can accurately measure the minute undulations on the surface of the ceramic tile, thereby improving the detection accuracy. Moreover, the entire detection process is automated, minimizing manual intervention as much as possible, improving the detection efficiency and consistency. At the same time, automated detection also reduces errors caused by human factors. Therefore, the application of this device helps ceramic tile production enterprises establish a more rigorous quality management system, promptly discover and correct problems in the production process, thereby improving product quality and market competitiveness. At the same time, through data accumulation and analysis, it can also provide strong support for product improvement and process optimization.

[0062] For further illustration, it also includes a standard gauge block 6, and the standard gauge block 6 has a standard thickness value. In an optional embodiment, as Figure 3-4 shown, a standard gauge block 6 with a thickness of 5 mm is used as the system reference.

[0063] Before measuring the ceramic tile to be measured, first place the standard gauge block 6 with a thickness of 5 mm under the three digital display dial indicators 33 respectively for measurement, record these three values respectively as the calibration values of the three digital display dial indicators 33, and input them into the data acquisition module 4 corresponding to each digital display dial indicator 33. After measuring the ceramic tile to be measured, the measured value of each digital display dial indicator 33 will be subtracted by the corresponding calibration value as the measured value for flatness calculation, that is, during measurement, the height change of the ceramic tile surface is relative to the standard gauge block 6 with a thickness of 5 mm.

[0064] As Figure 6 shown in the initial position in, it is not necessary to make the tips of the three digital display dial indicators 33 at the same height level before measurement. Because it is difficult to adjust the tips of the three dial indicators to be at the same height level and the initial value is 0, a 5 mm height plane with a size of 5 mm × 9 mm × 30 mm of a 5 mm thickness gauge block is used as the reference plane, that is, the calibration plane. The data measured by the digital display dial indicator 33 on the ceramic tile surface minus the data measured by the digital display dial indicator 33 on the reference plane is the value used for calculating the flatness.

[0065] As Figure 6As shown, the numerical calibration values measured by the three digital dial indicators 33 for the reference plane are 3.5 mm, 2 mm, and 3 mm respectively. For the three digital dial indicators 33 measuring the surface of the ceramic tile, assuming the tile thickness is 8 mm and the surface is very flat, the data are 6.5 mm, 5 mm, and 6 mm. Then the data actually used to calculate the flatness are 6.5 - 3.5 = 3 mm, 5 - 2 = 3 mm, and 6 - 3 = 3 mm. This subtraction process is implemented on the host computer software. The calibration values will be input once on the host computer software, and the data of the 9 measurement points read by the host computer will be subtracted from the corresponding calibration values respectively. It can be seen that this is exactly the value obtained by subtracting the 5 mm thickness gauge from the tile thickness. So the 5 mm thickness gauge is used as the reference plane. In actual measurement, for an 8 mm thick ceramic tile, since the surface flatness varies, its measured value changes around 3 mm.

[0066] Therefore, for ceramic tiles of different thicknesses, their measured values are relative to the surface of the 5 mm thickness gauge, that is, the reference plane. For example, when measuring a 9 mm thick ceramic tile, the data used to calculate the flatness change around 4 mm according to the above method; when measuring a 10 mm thick ceramic tile, the data used to calculate the flatness is around 5 mm according to the above method.

[0067] Therefore, for ceramic tiles of different thicknesses, only the range of the measured values changes, and the calculation process of the flatness is not affected. So the present utility model can realize the measurement and calculation of the surface flatness of ceramic tiles of different thicknesses.

[0068] For further illustration, the transmission module 1 includes a transmission platform 11 and transmission mounting brackets 12 arranged along both sides of the transmission platform 11;

[0069] The transmission mounting brackets 12 are provided with transmission mounting grooves 13 along their length directions, and both ends of the arched mounting bracket 5 are detachably mounted in the transmission mounting grooves 13 on both sides.

[0070] As Figure 1 shown, the transmission platform 11, as the main carrier for the movement of the ceramic tile, can be selected as a rotating type or a non-rotating type according to the needs of the user. The rotating transmission platform 11 is driven by a power device such as a motor to realize the automatic transmission of the ceramic tile; while the non-rotating transmission platform 11 relies on manual translation by workers to save equipment costs. By allowing the user to select a rotating or non-rotating transmission platform 11 according to actual needs, it not only meets the requirements of automated production but also takes into account cost-effectiveness. This flexibility enables the device to be widely used on ceramic tile production lines of different scales and with different requirements. At the same time, the design of the transmission mounting grooves 13 on the transmission mounting brackets 12 not only provides a stable installation foundation for the arched mounting bracket 5 and other modules but also makes the entire device structure compact, easy to assemble and maintain.

[0071] For further illustration, the trigger module 2 includes a trigger mounting base 21, a light blocking scale 22, a sensor mounting base 23, and a transmissive infrared sensor 24;

[0072] The trigger mounting base 21 is mounted on the conveying platform 11. The lower surface of the light blocking scale 22 is mounted on the trigger mounting base 21. The light blocking scale 22 is detachably and spacedly mounted with light blocking sheets 25. The light blocking scale 22 is made of a transparent material, and the light blocking sheets 25 are made of a non-transparent material;

[0073] The sensor mounting base 23 is detachably mounted in one of the conveying mounting grooves 13 of the conveying mounting bracket 12. The transmissive infrared sensor 24 is mounted on the sensor mounting base 23. The transmissive infrared sensor 24 includes a transmitter and a receiver, and there is a transmissive space between the transmitter and the receiver;

[0074] When the conveying platform 11 drives the light blocking scale 22 on the sensor mounting base 23 to move, the light blocking scale 22 movably penetrates through the transmissive space of the transmissive infrared sensor 24. When the light blocking sheet 25 on the light blocking scale 22 passes through the transmissive space of the transmissive infrared sensor 24, the transmissive infrared sensor 24 triggers a signal and synchronously triggers the data acquisition module 4 to collect and record the data of the corresponding surface feature points on the measured ceramic tile measured by the measurement module 3.

[0075] As Figure 2 shown, first of all, the trigger mounting base 21 is firmly mounted on the conveying platform 11 as the support basis for the light blocking scale 22. The light blocking scale 22 is made of a transparent material to ensure unobstructed penetration of the infrared light of the transmissive infrared sensor 24, while the light blocking sheets 25 spacedly mounted thereon are made of a non-transparent material to block the infrared light and form a trigger signal. The position of the light blocking sheets 25 on the light blocking scale 22 is detachably mounted, which is convenient for adjustment according to the actual characteristics of the ceramic tile surface.

[0076] Secondly, the sensor mounting base 23 is mounted in the conveying mounting groove 13 of the conveying mounting bracket 12 to provide a stable mounting environment for the transmissive infrared sensor 24. The transmissive infrared sensor 24 consists of a transmitter and a receiver, and a transmissive space is formed between the two. When there is no obstacle, the infrared light emitted by the transmitter can be smoothly received by the receiver; when an obstacle enters the transmissive space, the intensity of the light received by the receiver will change, thus triggering a signal.

[0077] As the transfer platform 11 moves, the light-blocking cursor scale 22 also moves accordingly. When the light-blocking piece 25 on the light-blocking cursor scale 22 enters the opposed space of the opposed infrared sensor 24, it will block the infrared light, resulting in a sharp drop in the light intensity received by the receiver. This change is recognized by the sensor as a trigger signal, and then the data acquisition module 4 is synchronously triggered through electrical connection to collect and record the data measured by the measurement module 3 at this moment. Since the interval of the light-blocking piece 25 on the light-blocking cursor scale 22 is known, the data acquisition module 4 can be synchronously triggered to collect and record the data of the tile surface measured by the measurement module 3 by calculating the time or quantity of the light-blocking piece 25 passing through the opposed space, realizing the accurate measurement of the characteristic points on the tile surface.

[0078] In summary, by adopting the non-contact opposed infrared sensor 24 and a simple mechanical structure, the trigger module 2 ensures high-precision triggering while reducing the manufacturing cost and usage cost of the device. This makes the device have high promotion value and application prospects in small and medium-sized tile production enterprises.

[0079] For further illustration, the measurement module 3 includes three groups of measurement sub-modules, and the measurement sub-modules are detachably installed on the arched mounting bracket 5;

[0080] The measurement module 3 includes a measurement mounting base 31, a measurement mounting rod 32, and a digital display dial indicator 33;

[0081] The measurement mounting base 31 is provided with a mounting portion 34, the arched mounting bracket 5 is provided with a clamping groove 35, and the mounting portion 34 is installed in the clamping groove 35 through a fastener;

[0082] One end of the measurement mounting base 31 away from the measurement mounting base 31 is provided with a measurement mounting through hole, the measurement mounting rod 32 is movably installed in the measurement mounting through hole, and the digital display dial indicator 33 is installed at the lower end of the measurement mounting rod 32.

[0083] Such as Figure 1As shown, the arched mounting bracket 5 serves as the support structure of the measurement module 3, and its design fully considers the stability and flexibility of measurement. The arched mounting bracket 5 is provided with a clamping groove 35 for cooperating with the mounting portion 34 on the measurement mounting base 31 to achieve stable clamping and installation. This installation method not only simplifies the installation process but also improves the stability of the measurement module 3. One end of the measurement mounting base 31 far from the mounting portion 34 is provided with a measurement mounting through hole, so that the measurement mounting rod 32 can be movably installed in the measurement mounting through hole, allowing it to be adjusted up and down or left and right within a certain range to adapt to the measurement requirements of different tile surfaces. Moreover, a digital display dial indicator 33 is installed at the lower end of the measurement mounting rod 32. As the core component for measuring the flatness of the tile surface, the digital display dial indicator 33 is a high-precision measuring instrument that can display the measurement value in real time and has high measurement accuracy and stability.

[0084] For further explanation, the measurement module 3 further includes a measurement scale 36, and the measurement scale 36 is arranged on the conveying platform 11. As Figure 1 shown, the scale is arranged along the length direction perpendicular to the conveying platform 11. Due to its own scale value, the scale can be used to measure the length of the measured tile and the distance between the surface feature points on the measured tile, saving measurement time.

[0085] For further explanation, the data acquisition module 4 includes a storage box 41, an OLED display screen 42, and a single-chip microcomputer 43;

[0086] The storage box 41 is installed on the arched mounting bracket 5, the OLED display screen 42 is exposed outside the storage box 41, and the single-chip microcomputer 43 is built in the storage box 41;

[0087] The single-chip microcomputer 43 includes a control processing unit 431, a digital display dial indicator data acquisition unit 432, a transmissive infrared sensing trigger acquisition unit 433, an OLED data display unit 434, and a serial communication unit 435 that are electrically connected to each other;

[0088] The control processing unit 431 is used to coordinate the control and processing of the digital display dial indicator data acquisition unit 432, the transmissive infrared sensing trigger acquisition unit 433, the OLED data display unit 434, and the serial communication unit 435;

[0089] The digital display dial indicator data acquisition unit 432 is used to acquire the surface feature point data of the measured tile acquired by the digital display dial indicator 33;

[0090] The transmissive infrared sensing trigger acquisition unit 433 is used to acquire the trigger signal of the transmissive infrared sensor 24;

[0091] The OLED data display unit 434 is used to display the surface feature point data collected from the status of the digital display dial indicator 33;

[0092] The serial communication unit 435 is used to transmit the surface feature point data to an external data processing module in real time.

[0093] As Figure 6-8 shown, first of all, the storage box 41, as the carrier of the data acquisition module 4, is installed on the arched mounting bracket 5 to provide protection for electronic components such as the single-chip microcomputer 43. The OLED display screen 42 is exposed outside the storage box 41, facilitating users to directly view the measurement data and the device status.

[0094] Secondly, the single-chip microcomputer 43 is the core of the data acquisition module 4. It integrates multiple functional units inside, including a control processing unit 431, a digital display dial indicator data acquisition unit 432, an opposed infrared sensing trigger acquisition unit 433, an OLED data display unit 434, and a serial communication unit 435. These units are interconnected through an internal bus to achieve data exchange and processing, realize centralized control and processing of data, and achieve intuitive display and remote transmission of data through the OLED display screen 42 and the serial communication unit 435. The specific circuit schematic diagram is as Figure 6 shown, the specific architecture schematic diagram is as shown in 7, and the specific process schematic diagram is as shown in 8.

[0095] 1. Optimization of digital display dial indicator data transmission:

[0096] As Figure 8 shown, by using the digital display dial indicator 33 to efficiently complete the precise measurement of the height of the tile surface, its measurement data is transmitted to the single-chip microcomputer in the form of a serial signal through a dedicated data output port. This serial signal contains two key signals - the clock signal SCL and the data signal SDA, ensuring the synchronization and accuracy of data transmission. The data signal SDA is valid at each rising edge of the clock signal SCL and is encoded in a 24-bit binary format. The data arrangement follows the international standard of low bits first and high bits later, facilitating rapid parsing and processing.

[0097] 2. Optimization of the position recognition of the opposed infrared sensor:

[0098] The opposed infrared sensor 24 accurately recognizes the positions of the front and back surface feature points on the measured tile and outputs a level signal through the occlusion state of the light-blocking scale 22. When there is no occlusion, a stable high level is output. Once a light-blocking piece 25 passes through with its position precisely corresponding to the surface feature point, an immediate clear falling edge signal is generated. This signal serves as a trigger point, which is immediately captured by the single-chip microcomputer 43 and the data measured by the dial indicator at this time is marked as valid data, that is, the accurate reading of the tile surface feature point. The measurement data in the non-trigger state is regarded as invalid, effectively avoiding data redundancy and misreading.

[0099] 3. Optimization of the Status and Data Visualization of the OLED Display Screen 42:

[0100] The OLED display screen 42 intuitively shows the working status and real-time measurement data of the digital display dial indicator 33, enhancing the friendliness of the operation interface and information transparency. When the digital display dial indicator 33 is not connected or not turned on, the display screen immediately shows "OFF", clearly indicating the non-working state of the device; once the digital display dial indicator 33 is normally connected and started, it switches to the "ON" state, indicating that the digital display dial indicator 33 is ready. At the same time, the OLED display screen 42 dynamically updates the real-time measurement data of the three digital display dial indicators 33, facilitating the staff to monitor and evaluate the measurement process in real time.

[0101] 4. Optimization of the Data Transmission Protocol between the Single-Chip Microcomputer 43 and the Host Computer:

[0102] The single-chip microcomputer 43 efficiently and accurately transmits the measurement data of the three digital display dial indicators 33 to the host computer through the USART communication protocol. To ensure the reliability and integrity of data transmission, a custom data frame format is adopted. Each frame contains 18 hexadecimal numbers. The first two and the last two digits are data check bits for verifying data integrity; the 3rd and 4th bits are data valid flag bits to clearly distinguish between valid and invalid measurement data; the 5th - 16th bits respectively correspond to the measurement data of the three digital display dial indicators 33, arranged in order from left to right, as Figure 9 shown, facilitating the host computer to quickly parse and store, and finally achieving a comprehensive and accurate measurement of 9 key feature points on the tile surface.

[0103] 5. Optimization of Host Computer Data Processing:

[0104] The host computer is mainly used to receive the data collected by the STM32 single-chip microcomputer, and at the same time input relevant data such as tile size on the front panel. The data processing program will calculate the flatness information of the tile based on this data, and finally display the result on the front panel of the program. It mainly consists of a data reading part, a central camber and warp calculation part, an edge camber calculation part, and a data processing result display and saving part. Each part is a thread, and communication between the threads is carried out through a message queue, as Figure 11 shown.

[0105] Among them, the data reading part completes the reading of the data transmitted by the single-chip microcomputer 43, extracts the data of the points to be measured on the tile surface from these data, and at the same time reads the parameters input on the display front panel.

[0106] As Figure 12The following is the data reading flowchart. At the beginning, initialization is performed to identify whether the serial port is connected. Then, an array DATA[] for saving the data of 9 points to be measured on the tile surface is declared. Next, a loop is entered, and in the loop, the data transmitted through the serial port is continuously read. According to the defined data format, it is judged whether the data is correct. Incorrect data is discarded, and correct data is judged whether it is the data of the points to be measured on the valid data tile surface. If not, continue to read. If so, it is stored in the data DATA[]. When the data of 9 measurement points is saved in DATA[], the array is stored in message queue 1. At the same time, parameters such as the tile size input on the front panel are also stored in message queue 1 for the flatness calculation program to read these data for calculation.

[0108] It should be noted that as long as the control processing chip U3 can implement the functions of processing, displaying, and transmitting the data collected by the measurement module 3 as described above, it falls within the protection scope of the present invention.

[0109] For further explanation, the digital display dial indicator data acquisition unit 432 includes a digital display dial indicator data acquisition chip U1, a potentiometer R1, digital display dial indicator socket ports U4, U5, and U6;

[0111] For further explanation, the model of the digital display dial indicator data acquisition chip U1 is TXS0108EQPWRQ1.

[0112] As an optional embodiment, the digital display dial indicator data acquisition chip U1 in this embodiment adopts TXS0108EQPWRQ1.

[0113] It should be noted that as long as the control processing chip U3 can implement the function of processing the data collected by the digital display dial indicator 33 as described above, it falls within the protection scope of the present invention.

[0114] The specific working principle of the present invention is as follows:

[0115] 1. Installation and adjustment of the digital display dial indicator 33:

[0116] On the arched mounting bracket 5, through the measuring mounting base 31 and the measuring mounting rod 32, multi-dimensional flexible adjustment of the position of the digital display dial indicator 33 is achieved. Among them, the measuring mounting base 31 is firmly connected to the arched mounting bracket 5 by bolts, allowing lateral fine adjustment on the arched mounting bracket 5 by loosening the bolts to precisely control the left and right positions of the three digital display dial indicators 33. Moreover, each measuring mounting rod 32 is fixed to the measuring mounting base 31 by fastening bolts, further supporting the up and down adjustment function of the digital display dial indicator 33. The digital display dial indicator 33 is installed below the measuring mounting rod 32 through a flexible dial indicator fixing clip, and the fixing clip can rotate around the measuring mounting rod 32 to achieve fine adjustment of the front and back angles of the dial indicator. This series of designs ensures that the digital display dial indicator 33 can comprehensively cover and accurately align different measurement points on the surface of the measured ceramic tile, and can achieve precise adaptation in terms of left and right, up and down, and front and back positions.

[0117] 2. Installation and adjustment of the transmissive infrared sensor 24:

[0118] The sensor mounting base 23 is installed in one of the conveyor mounting grooves 13 of the conveyor platform 11, and the transmissive infrared sensor 24 mounted thereon can flexibly set its optimal detection point by adjusting the position of the mounting bolts. This design ensures that the transmissive infrared sensor 24 can accurately capture the key signals during the movement of the measured ceramic tile.

[0119] 3. Installation and adjustment of the auxiliary tool and the conveyor platform:

[0120] The 2-mm-wide measuring scale 36 inlaid in front of the conveyor platform 11 not only serves as a reference for the front and back limits of the ceramic tile but also assists in dimension calibration. The two ends of the arched mounting bracket 1 are tightly installed in the conveyor mounting grooves 13 on both sides of the conveyor platform 11 to ensure the stable sliding of the conveyor platform 11 during the measurement process. The transparent light-blocking scale 22 on the conveyor platform 11 cooperates with the three light-blocking pieces 25 at precise positions to effectively trigger the transmissive infrared sensor 24 and realize automatic identification and data acquisition of the measurement points.

[0121] 4. Data acquisition and processing module:

[0122] The high-performance single-chip microcomputer 43 built into the storage box 41 is directly connected to the digital display dial indicator 33 through a data cable, and the measurement data of the digital display dial indicator 33 is captured in real time through the digital display dial indicator data acquisition unit 432. The single-chip microcomputer 43 also integrates the signal recognition function of the transmissive infrared sensor 24 - the transmissive infrared sensing trigger acquisition unit 433 to ensure that valid data is recorded only when the light blocking piece 25 passes by. The surface feature point data of the measured ceramic tile collected is instantaneously fed back on the OLED display screen 42 through the OLED data display unit 434, and the surface feature point data can be transmitted in real time to an external data processing module through the serial communication unit 435. The data processing module calculates the flatness of the tile according to the national detection specifications, and grades, displays, and saves the data according to the standards set by the manufacturer.
