Description

Technical Field

[0001] This invention relates to the field of detection device technology, and in particular to a device for detecting hollowness in floor tiles used in interior decoration. Background Technology

[0002] Hollow tiles are a common quality defect in interior decoration construction and acceptance. If they are not detected and treated in time, they will crack and fall off later, affecting the aesthetics and safety of the decoration. Therefore, the detection of hollow tiles is a key link in the quality control of interior decoration.

[0003] Currently, most devices only have a single tapping or detection function, and detection and marking are independent of each other, requiring manual secondary positioning. They cannot achieve simultaneous completion of hollow tile detection and position marking, resulting in low positioning accuracy. During the detection process, construction dust and sand particles remaining on the tile surface can interfere with the signal acquisition of the vibration sensor, reducing the accuracy of hollow tile judgment and affecting the ink marking of hollow tile positions. Furthermore, existing devices do not have a dedicated cleaning mechanism, requiring manual cleaning of the tile surface beforehand, which increases the operation steps. The tapping mechanism of existing devices is mostly single-point or local tapping, making it difficult to achieve continuous, uniform, and blind-angle-free automated scanning detection of large areas of floor tiles. The detection efficiency is low, and the tapping force of the device is unstable, which can easily cause jamming or excessive impact, affecting detection accuracy and potentially damaging the tiles. Therefore, this application proposes a hollow tile detection device for indoor decoration floor tiles. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art, such as uneven tapping force, low detection efficiency, and dust affecting detection accuracy, by proposing a hollow detection device for floor tiles used in indoor decoration.

A storage tube is fixedly installed, and a sealing plate is slidably installed inside the storage tube. A cylinder is fixedly installed on the main board, and the piston rod of the cylinder is fixedly connected to the sealing plate. A one-way valve is fixedly installed on the sealing plate, and the one-way valve can only allow air to enter in one direction. A connecting pipe is fixedly installed at the bottom of the storage tube, and an electronic valve is fixedly installed on the connecting pipe. One end of the connecting pipe is connected to a connecting cavity. An ink outlet is opened on the striking ball, and the ink outlet is connected to the connecting cavity. A vibration sensor is installed inside the striking ball. A processor and a controller are installed inside the main board. The output end of the vibration sensor is connected to the input end of the processor, and the output end of the controller is connected to the input end of the controller. The output end of the controller is connected to the starting end of the electronic valve and the cylinder.

[0007] Optionally, the cleaning mechanism includes a track frame fixedly mounted on a fixed block, a connecting block slidably mounted on the track frame, a guide rod hinged to the connecting block, one end of the guide rod hinged to one side of the connecting cavity, a threaded rod threadedly connected to the connecting block, a square plate slidably mounted on the bottom of the connecting block, a cleaning block fixedly mounted on the bottom of the square plate, a conical block slidably mounted inside the cleaning block, a second spring fixedly mounted on the top of the conical block, pressure sensors fixedly mounted on both sides of the conical block, a contact plate fixedly mounted inside the cleaning block, and the output end of the pressure sensor connected to the input end of the processor.

[0008] Optionally, a first spring is fixedly installed on the base plate, and one end of the first spring is fixedly connected to the fixing block.

[0009] Optionally, a fixing post is fixedly installed at the bottom of the mounting block, and the fixing post is fixedly connected to the fixing block.

[0010] Optionally, a one-way feed port is fixedly installed on the sealing plate, and the one-way feed port can only feed in one direction.

[0011] Optionally, a first motor is fixedly mounted on one side of the first mounting frame, and the output shaft of the first motor is fixedly connected to the first reciprocating lead screw.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention achieves fully automatic, large-area, uniform, and blind-angle-free tapping detection of floor tiles by forming a three-axis linkage through the first reciprocating lead screw, the second reciprocating lead screw, and the turntable guide tapping mechanism. It has high detection efficiency and low labor intensity. Before tapping, the bottom cleaning block is driven by the connecting cavity to clean the part to be tapped, avoiding dust interference with the vibration sensor signal acquisition, improving the accuracy of hollow tile detection, and ensuring clear marking.

[0016] Furthermore, by integrating the vibration sensor into the striking ball, the detection point and the marking point are highly aligned, enabling simultaneous completion of hollow detection and position marking. This ensures precise positioning without misalignment. Through cylinder reset and a one-way valve, residual ink in the pipeline and striking ball flows back to the storage tube, fundamentally avoiding mismarking and tile contamination caused by residual ink dripping. Water-based erasable ink is used, resulting in clear markings, fast drying, and moderate adhesion. It does not corrode the tile glaze and can be easily wiped off, protecting the finished decoration.

[0017] Furthermore, by using a cone-shaped block installed on the cleaning block, when the cone-shaped block comes into contact with the tile gap, the pressure sensor on the cone-shaped block transmits a signal to the controller, stopping the detection of hollow spots in the tile and ink spraying, thus avoiding accidental ink spraying in the gap.

[0018] This invention realizes fully automatic three-axis uniform scanning and tapping of hollow tiles, automatic dust removal before tapping, real-time sound wave detection, instant and accurate marking of hollow tile positions, and residual ink return after marking to prevent mismarking.

[0027] Example 1 like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a hollow tile detection device for indoor decoration floor tiles, including a main board 1 and a column 2. The column 2 is fixedly installed on the main board 1, and a handrail 3 is fixedly installed on the column 2. Multiple casters are fixedly installed on the bottom of the main board 1 to facilitate movement of the main board 1. A first mounting frame 4 is fixedly installed on the main board 1, and a second mounting frame 6 is slidably installed on the first mounting frame 4. A mounting block 10 is slidably installed on the second mounting frame 6, and a top plate 21 is slidably installed on the mounting block 10. The top of the top plate 21 is cut, and a bottom plate 23 is fixedly installed on the bottom of the top plate 21. A connecting cavity 24 is fixedly installed on the bottom of the bottom plate 23. The connecting cavity 24 is hollow, and a striking ball 25 is fixedly installed at one end of the connecting cavity 24. The main board 1 is provided with a marking device that automatically marks when the striking ball 25 detects a hollow tile, and the main board 1 is provided with a cleaning mechanism that cleans the striking ball 25 before striking it.

[0028] Example 2 like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the marking mechanism is rotatably mounted in the first mounting frame 4 with a first reciprocating screw 5 threadedly connected to the second mounting frame 6. A second reciprocating screw 8 is rotatably mounted in the second mounting frame 6 and threadedly connected to the mounting block 10. A first rotating wheel 16 is rotatably mounted on the mounting block 10. A connecting plate 15 is fixedly mounted on one side of the mounting block 10, and a second rotating wheel 17 is rotatably mounted on the connecting plate 15. A connecting belt 18 is sleeved between the first rotating wheel 16 and the second rotating wheel 17. A turntable 14 is fixedly mounted on one side of the second rotating wheel 17, and a guide block 19 is fixedly mounted on the turntable 14. One end of the guide block 19 is arc-shaped. A fixing block 20 is fixedly mounted on the bottom of the mounting block 10. The guide block 19 is slidably connected to the top plate 21 and fits against the cut surface of the top plate 21. A storage tube 31 is fixedly installed on the main board 1. The storage tube 31 stores water-based erasable ink, which is composed of deionized water, water-based dye, a small amount of ethanol and non-ionic surfactant. It has the characteristics of fast drying speed, moderate adhesion, no corrosion to the tile glaze, and easy erasure with a damp cloth. It can mark the hollow position in real time without contaminating or damaging the tile surface. A sealing plate 34 is slidably installed inside the storage tube 31. A cylinder 32 is fixedly installed on the main board 1. The piston rod of the cylinder 32 is fixedly connected to the sealing plate 34. A one-way valve 35 is fixedly installed on the sealing plate 34. The one-way valve 35 can only allow air to enter in one direction. A storage tube 31 is fixedly installed at the bottom. A connecting pipe 29 is used, on which an electronic valve 30 is fixedly installed. One end of the connecting pipe 29 is connected to the connecting cavity 24. An ink outlet 26 is provided on the striking ball 25, which is connected to the connecting cavity 24. A vibration sensor is installed inside the striking ball 25. The vibration sensor is a Xiamen Naier CAYD210V-100A model, characterized by wide frequency range, low temperature drift, high voltage output, and small size, making it suitable for embedding in the striking ball 25. It is used to detect the sound waves and vibration signals generated by the ceramic tile. The main board 1 contains a processor and a controller. The processor extracts and processes the signal characteristics and determines whether a hollow sound phenomenon occurs. The output of the vibration sensor is connected to the input of the processor, and the output of the controller is connected to the input of the controller. The output end is connected to the starting end of the electronic valve 30 and the cylinder 32. Rotating the first rotating wheel 16 drives the second rotating wheel 17 to rotate via the connecting belt 18. The second rotating wheel 17 drives the turntable 14 to rotate. The guide block 19 on the turntable 14 continuously presses against the cut surface of the top plate 21. As the guide block 19 presses, the top plate 21 moves downward. As the turntable 14 rotates, the top plate 21 reciprocates in the vertical direction. The top plate 21 drives the striking ball 25 at the bottom to strike the tiles. This is coordinated with the rotation of the first reciprocating screw 5, which drives the second mounting frame 6 to reciprocate horizontally on the first mounting frame 4. Rotating the second reciprocating screw 8 drives the mounting block 10 to reciprocate horizontally.This allows the striking ball at the bottom of mounting block 10 to evenly strike the tiles within the trajectory range of the first mounting frame 4 and the second mounting frame 6. The first reciprocating screw 5 and the second reciprocating screw 8 achieve X and Y direction planar scanning, while the turntable 14, guide block 19, and the cut surface of the top plate 21 achieve continuous striking in the Z direction. These three components work together to achieve automated, blind-angle-free, and uniform striking of the entire area, replacing manual or single-point striking and improving detection efficiency by 40%. A vibration sensor collects the striking signals, which are then processed by a processor to determine if there is hollowness. The processing results are transmitted to the controller. If an empty drum is detected, the controller opens the electronic valve 30, coordinating with the start cylinder 32. The piston rod of cylinder 32 pushes down the sealing plate 34, delivering water and ink to the connecting pipe 29. The water and ink in the connecting pipe 29 enter the connecting cavity 24 and are finally discharged through the ink outlet 26, marking the empty drum position. After marking, cylinder 32 resets, coordinating with the one-way valve 35 to allow residual ink in the striking ball 25, connecting cavity 24, and connecting pipe 29 to flow back into the storage pipe 31, preventing mismarking caused by residual ink inside the equipment during striking.

[0029] Example 3 like Figure 3 , Figure 7 and Figure 8As shown, the cleaning mechanism includes a track frame 37 fixedly mounted on a fixed block 20. A connecting block 43 is slidably mounted on the track frame 37. A guide rod 36 is hinged to the connecting block 43, with one end of the guide rod 36 hinged to one side of the connecting cavity 24. A threaded rod 27 is threadedly connected to the connecting block 43. A square plate 28 is slidably mounted on the bottom of the connecting block 43. A cleaning block 38 is fixedly mounted on the bottom of the square plate 28. A conical block 39 is slidably mounted inside the cleaning block 38. A second [unclear - possibly a component or part] is fixedly mounted on the top of the conical block 39. Pressure sensors 41 are fixedly installed on both sides of the spring 40 and the conical block 39. A contact plate 42 is fixedly installed inside the cleaning block 38. The output end of the pressure sensor 41 is connected to the input end of the processor. When a hollow area detection is required, the threaded rod 27 is rotated, which moves the square plate downward, moving the cleaning block 38 downward until it contacts the tile. When the connecting cavity 24 moves upward, it pulls the guide rod 36, which in turn moves the connecting block 43 to the left on the track frame 37. When the connecting block 43 moves, the cleaning block 38 at the bottom of the square plate 28 moves to the bottom of the striking ball 25 to clean the dust on the part of the striking ball 25 to be struck. When the connecting cavity 24 moves downward, it squeezes the guide rod 36, which in turn squeezes the connecting block 43, causing it to move to the right. The connecting block 43 then moves the cleaning block 38 to the right, away from the striking ball 25, to prevent the striking ball 25 from impacting the cleaning block 38 and affecting the hollow detection. As the first mounting frame 4 and the second mounting frame 6 move, the cleaning block 38 is also prevented from erasing the hollow mark. When the cleaning block 38 contacts the tile gap, the second spring 40 moves the bottom of the conical block 39 downward into the tile gap. When the conical block 39 moves downward, it causes the pressure sensor 41 to contact the contact plate 42. The pressure sensor 41 detects the pressure signal and transmits the signal to the controller. The controller then controls the electronic valve 30, the cylinder 32, and the second motor to close, stopping the hollow detection and inkjet printing, thus preventing accidental inkjet printing in the gap.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a first spring 22 is fixedly installed on the base plate 23, and one end of the first spring 22 is fixedly connected to the fixing block 20. A fixing post 11 is fixedly installed on the bottom of the mounting block 10, and the fixing post 11 is fixedly connected to the fixing block 20. A one-way feed port 33 is fixedly installed on the sealing plate 34. The one-way feed port 33 can only feed in one direction and is used to add water-based ink into the storage tube 31. A first motor 7 is fixedly installed on one side of the first mounting frame 4. The output shaft of the first motor 7 is fixedly connected to the first reciprocating screw 5. When the first motor 7 is started, the output shaft of the first motor 7 drives the first reciprocating screw 5 to rotate. A mounting frame 12 is fixedly installed, and a second motor 13 is fixedly installed on the mounting frame 12. The output shaft of the second motor 13 is fixedly connected to the first rotating wheel 16. The output end of the controller is connected to the starting end of the second motor 13. When the second motor 13 is started, the output shaft of the second motor 13 drives the first rotating wheel 16 to rotate. A third motor 44 is fixedly installed on one side of the second mounting frame 6. The output shaft of the third motor 44 is fixedly connected to the second reciprocating lead screw 8. When the third motor 44 is started, the output shaft of the third motor 44 drives the second reciprocating lead screw 8 to rotate. A sliding groove 9 is provided on the second mounting frame 6, and the mounting block 10 is slidably connected to the sliding groove 9.

[0031] Working principle: Rotating the first rotating wheel 16 drives the second rotating wheel 17 to rotate via the connecting belt 18. The second rotating wheel 17 drives the turntable 14 to rotate. The guide block 19 on the turntable 14 continuously presses against the cut surface of the top plate 21. As the guide block 19 presses, the top plate 21 moves downward. With the rotation of the turntable 14, the top plate 21 reciprocates vertically. The top plate 21 drives the striking ball 25 at the bottom to strike the tiles. This, combined with the rotation of the first reciprocating screw 5, causes the second mounting frame 6 to reciprocate horizontally on the first mounting frame 4. Rotating the second reciprocating screw 8 causes the mounting block 10 to reciprocate horizontally, thus... The striking ball at the bottom of block 10 can evenly tap the tile within the trajectory range of the first mounting frame 4 and the second mounting frame 6. The striking signal is collected by a vibration sensor and then processed by a processor to determine if there is a hollow area. The processing result is transmitted to the controller. If a hollow area is found, the controller controls the electronic valve 30 to open, which in turn activates the cylinder 32. The piston rod of the cylinder 32 drives the sealing plate 34 to press down, delivering water and ink into the connecting pipe 29. The water and ink in the connecting pipe 29 enter the connecting cavity 24 and finally exit through the ink outlet 26, marking the hollow area. After marking, the cylinder 32 resets, and in conjunction with the one-way valve 35, the striking ball 25, the connecting cavity 24, and the connecting pipe 29 are connected. Residual ink flows back into the storage tube 31 to prevent mislabeling caused by residual ink inside the equipment during tapping. When a hollow sound test is required, the threaded rod 27 is rotated, causing the square plate to move downwards, moving the cleaning block 38 downwards until it contacts the tile. When the connecting cavity 24 moves upwards, it pulls the guide rod 36, which in turn moves the connecting block 43 to the left on the track frame 37. At this time, the connecting block 43 moves the cleaning block 38 at the bottom of the square plate 28 to the bottom of the striking ball 25 to clean the dust on the part of the striking ball 25 to be tapped. When the connecting cavity 24 moves downwards, it squeezes the guide rod 36, which in turn squeezes the connecting block 43. The connecting block 43 moves the cleaning block 38 to the right, moving it away from the striking ball 25 to prevent the striking ball 25 from impacting the cleaning block 38 and affecting the hollow detection. As the first mounting frame 4 and the second mounting frame 6 move, the cleaning block 38 is also prevented from erasing the hollow mark. When the cleaning block 38 contacts the tile gap, the second spring 40 moves the bottom of the conical block 39 downward into the tile gap. When the conical block 39 moves downward, it causes the pressure sensor 41 to contact the contact plate 42. The pressure sensor 41 detects the pressure signal and transmits the signal to the controller. The controller controls the electronic valve 30, the cylinder 32 and the second motor to close, stopping the hollow detection and inkjet printing.

[0032] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
