[0002] Stone plastic flooring, also known as stone plastic floor tiles, or formally as PVC sheet flooring, is a new type of floor decoration material made from stone powder and a high-molecular PVC wear-resistant layer as the main raw materials, through high-tech research and development and hundreds of processes.

[0003] Chinese patent CN108759688B discloses a laser detection device for the shape of a skateboard brick, comprising a transmission system and a detection system. The transmission system includes a housing, side plates, a support shaft, a sprocket shaft, a sprocket, and a ring conveyor belt. The detection system includes a bracket, a screw, a slider, and a laser sensor. The ring conveyor belt constitutes the Y-axis detection system, the movement of the slider on the screw constitutes the X-axis detection system, and the vertically downward signal path of the laser sensor on the slider constitutes the Z-axis detection system. The skateboard brick to be detected is placed on the ring conveyor belt and transported to a designated position. The system begins to collect the values ​​of the X, Y, and Z systems at fixed time intervals. By calculation, the coordinate values ​​of the tested skateboard brick in the system can be obtained. Based on the fact that all skateboard products have holes that allow molten steel to pass through, using this feature and the above calculation method, the key dimensions of the skateboard product, such as length, width, height, and hole diameter, can be calculated, thereby realizing automatic laser detection of the dimensions of the skateboard product.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the existing technologies, several points are selected on the stone plastic floor using laser sensors, and laser detection is performed on these points.

By pushing the electric push rod A, the laser sensor B can be used to draw vertical lines on the surface of the stone plastic flooring. The intersection points of the vertical and horizontal lines are identified, thereby determining the deformation value of the detection points. Because multiple detection points are found on the surface of the stone plastic flooring, the detection accuracy is improved.

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figure 1 , Figure 3 and Figure 11As shown, the present invention provides a technical solution: a laser-based temperature and humidity deformation detection device for stone plastic flooring, comprising a main housing 1, a control unit 3 disposed on the outer surface of the main housing 1, and laser detection components A5 and B6 disposed inside the main housing 1 for detecting the stone plastic flooring. Laser detection component A5 is located below laser detection component B6. The main housing 1 also contains a heating and cooling unit 7 and a humidifying and dehumidifying unit 8 for simulating and controlling temperature and humidity changes. Both the heating and cooling unit 7 and the humidifying and dehumidifying unit 8 are signal-connected to the control unit 3.

[0021] The control unit 3 includes a central processing module 31, which is signal-connected to a visual monitoring module 32. The visual monitoring module 32 is signal-connected to a model building module 33, which is signal-connected to a trajectory module 34. The trajectory module 34 is signal-connected to an intersection calculation module 35. The visual monitoring module 32 monitors the working screen, and the model building module 33 builds a scale model of the SPC flooring to be tested on the control unit 3. Next, the trajectory module 34 simulates the trajectory of the laser detection component B6 and combines the trajectory with the model. Finally, the intersection calculation module 35 calculates the intersection data of the trajectory to determine whether a thickness change occurs at each intersection. During operation, the SPC flooring to be tested is placed in the main housing 1, and the control unit 3 controls the laser detection component A5 and the laser... The detection component B6 performs deformation detection on the SPC flooring. Laser detection component A5 detects the lateral deformation of the SPC flooring, while laser detection component B6 detects the longitudinal deformation. The integrated heating and cooling unit 7 and the integrated humidification and dehumidification unit 8 inside the main housing 1 simulate the detection environment. By controlling variables, the deformation of the SPC flooring under various temperature and humidity conditions can be determined. Next, an industrial camera is installed on the laser detection component B6 to monitor the entire deformation detection process. The image is transmitted to the vision monitoring module 32, and a proportional model is created using the model building module 33. The laser detection component B6 is then activated, and laser lines are drawn on the surface of the SPC flooring, a certain number of lines in both the lateral and longitudinal directions. The intersection points of the lateral and longitudinal lines are taken, and the intersection point calculation module 35 calculates the intersection point data to determine whether deformation has occurred at the intersection point.

[0022] Reference Figure 3 and Figure 10The inner wall of the main housing 1 has a wall groove 11. The laser detection component B6 includes a wall block 61 and an electric push rod A62 disposed inside the wall groove 11. One end of the electric push rod A62 is connected to the inner wall of the wall groove 11, and the other end of the electric push rod A62 is connected to the wall block 61. A mounting block 63 is disposed on one side of the wall block 61. Two sets of wall blocks 61 are arranged opposite each other. A guide rod 64 is disposed between the two sets of mounting blocks 63. A sliding block 65 is sleeved on the outer surface of the guide rod 64. An electric push rod B69 is provided on one side of the sliding block 65. One end of the electric push rod B69 is connected to the mounting block 63. A housing 66 is provided at the lower end of the sliding block 65. A mounting plate 67 is provided at the lower end of the housing 66. A laser sensor B68 is provided at the lower end of the mounting plate 67. The wall block 61 can be moved along the wall groove 11 by the electric push rod A62. The sliding block 65 can be moved along the guide rod 64 by the electric push rod B69, thereby realizing the position adjustment of the laser sensor B68.

[0023] The internal casing 66 houses a motor, the motor output of which is connected to the mounting plate 67. Three sets of laser sensors B68 are installed. During operation, the laser sensors B68 can be used to draw horizontal lines on the surface of the stone plastic flooring to be tested by pushing the electric push rod B69. The laser sensors B68 can also be used to draw vertical lines on the surface of the stone plastic flooring to be tested by pushing the electric push rod A62. The intersection of the vertical and horizontal lines is found, thereby determining the deformation value of the detection point.

[0024] The laser detection component A5 includes a side groove formed in the inner wall of the main housing 1. An electric push rod C51 is installed in the side groove. A side block is provided at one end of the electric push rod C51. A side plate 52 is provided on one side of the side block. A vertical groove is formed on one side of the side plate 52. A laser sensor A53 is slidably installed in the vertical groove. An electric telescopic rod is also installed in the vertical groove. One end of the electric telescopic rod is connected to the laser sensor A53. The laser sensor A53 can be moved along the side groove by the electric push rod C51. The laser sensor A53 can be moved up and down slightly along the vertical groove by the electric telescopic rod. During operation, the deformation of the side of the stone plastic floor can be measured by the horizontal movement of the laser sensor A53.

[0025] Reference Figure 2 and Figures 4-9The main housing 1 has a placement component 9 inside. The placement component 9 includes a drive motor 91 located on one side of the main housing 1, a guide rail 99 located inside the main housing 1, and a placement plate 94 slidably located on the upper end of the guide rail 99. The main housing 1 has a cavity 12 inside, and a positioning block 98 is provided on the side wall of the cavity 12. A bottom block 96 is provided on the lower surface of the placement plate 94. A lead screw 97 is provided at the output end of the drive motor 91. One end of the lead screw 97 passes through the bottom block 96 and is movably connected to the positioning block 98. A section is provided on one side of the main housing 1. There is a feed inlet, which is opposite to the placement plate 94. Before the work starts, the drive motor 91 is started, and its output end drives the lead screw 97 to rotate, which in turn drives the bottom block 96 to move, thereby realizing the horizontal displacement of the placement plate 94. This moves the placement plate 94 from the feed inlet to the outside, making it easier for the staff to place the stone plastic flooring to be tested on the placement plate 94. After loading is completed, the drive motor 91 is restarted, and then the placement plate 94 is reset. The guide rail 99 is also installed on the inner wall of the cavity 12 to ensure that the placement plate 94 moves along the guide rail 99.

[0026] The cavity 12 also contains an internal plate 92. An insertion rod 93 is located on one side of the internal plate 92, and an insertion hole is formed on one side of the placement plate 94. An extension rod 941 is installed inside the insertion hole, and springs A942 are located on both sides of the extension rod 941. One end of each spring A942 is connected to the inner wall of the insertion hole, and a beveled head 943 is provided at one end of the extension rod 941. A recessed groove 95 is formed on the upper surface of the placement plate 94, communicating with the insertion hole. A limit block 951 is installed inside the recessed groove 95, and a beveled surface is formed on the lower bottom surface of the limit block 951. During testing, one end of the insertion rod 93 is located inside the insertion hole. At this time, the extension rod 941 is compressed and moves, causing one end of the extension rod 941 to move the beveled head 943, thereby causing the limit block 951 to move. The limit block 951 moves upward so that one side of the limit block 951 is in close contact with one side of the SPC flooring. In other words, before the work begins, the SPC flooring to be tested is placed on the placement plate 94, and one side of the SPC flooring is flush with the edge of the sink 95. When the placement plate 94 returns to the main housing 1, the limit block 951 is squeezed upward by the inclined head 943, thereby blocking one side of the SPC flooring with the limit block 951. This ensures that when the SPC flooring deforms, the deformation will only occur from the other side, making it easier for the laser sensor A53 to detect. After the detection is completed, the placement plate 94 moves to the left, the insertion rod 93 moves out of the insertion hole, the spring A942 resets, and the extension rod 941 resets, thereby causing the limit block 951 to move downward.

[0027] A feeding component 2 is provided on one side of the main housing 1, corresponding to the feeding port. The feeding component 2 includes a feeding box 21 located on one side of the main housing 1. A top block 22 is provided on the inner wall of the feeding box 21. An electric push rod D23 is provided on one side of the feeding box 21. The output end of the electric push rod D23 passes through the outer wall of the feeding box 21 and is connected to the top block 22. A spring C29 is provided on one side of the top block 22. One end of the spring C29 is connected to the inner wall of the feeding box 21. A scraper 24 is provided at the lower end of the top block 22. During the feeding process, as the placement plate 94 moves continuously, the upper surface of the stone plastic floor to be inspected will come into contact with the scraper 24, thereby using the scraper 24 to scrape away the stains on the upper surface of the stone plastic floor, improving the quality of subsequent laser inspection. An electric door 4 is provided on one side of the feeding box 21. During the inspection process, the electric door 4 is in the closed state.

[0028] The bottom surface of the top block 22 has a groove 28, and a protrusion 25 is provided in the groove 28. There are two sets of protrusions 25, and a connecting rod 26 is rotatably connected between the two sets of protrusions 25. A spring B27 is provided on the outer surface of the connecting rod 26, and one end of the spring B27 is connected to the inner wall of the groove 28. A pneumatic telescopic rod 261 is also provided on the outer surface of the connecting rod 26, and a cleaning cotton 262 is provided at one end of the pneumatic telescopic rod 261. A sealing groove is provided on one side of the top block 22. One end of the scraper 24 performs piston movement inside the sealing groove. The sealing groove is connected to the pneumatic telescopic rod 261 through a hose 263. During the feeding process, the upper surface of the stone plastic flooring will come into contact with the scraper 24. Since the scraper 24 has inclined surfaces on both sides, after the stone plastic flooring comes into contact with the scraper 24, the scraper 24 will move upward, squeezing the gas in the sealing groove, thereby... The pneumatic telescopic rod 261 extends, causing the cleaning cotton 262 to move downwards until its lower end contacts the upper surface of the placement plate 94. At this point, one side of the SPC flooring will contact the side of the cleaning cotton 262. The placement plate 94 then stops moving, and the electric push rod D23 is activated, causing the top block 22 to move left and right. This allows one side of the SPC flooring to move left and right across the surface of the cleaning cotton 262, improving the detection accuracy of the subsequent laser sensor A53. After wiping, the placement plate 94 continues to move, causing the SPC flooring to push the cleaning cotton 262, which in turn causes the pneumatic telescopic rod 261 to rotate until the SPC flooring passes through the cleaning cotton 262. At this point, the lower end of the cleaning cotton 262 will contact the upper surface of the SPC flooring, thus wiping the upper surface of the SPC flooring with the cleaning cotton 262 and improving the detection quality of the subsequent laser sensor B68.

[0029] One side of the flexible hose 263 is connected to a branch pipe, which is equipped with a pressure valve. The branch pipe is connected to the outside. After the test is completed, the placement plate 94 begins to move to the left. At this time, one side of the stone plastic floor will first contact the scraper 24, causing the scraper 24 to move upward. At this time, the pneumatic telescopic rod 261 cannot extend or retract due to the limitation of the stone plastic floor. The air pressure in the sealing groove increases, and the gas in the sealing groove will be discharged outward from the pressure valve. During the process of the placement plate 94 moving to the right, the air pressure is balanced, so the pressure valve in the branch pipe will not open.

[0030] Electric telescopic rods 13 are installed on both sides of the main housing 1. One end of the electric telescopic rod 13 is equipped with a side plate. The side plate is located inside the main housing 1 and is on the same horizontal line as the stone plastic floor to be tested. During the testing process, the electric telescopic rods 13 are used to press the side plate tightly against the two sides of the stone plastic floor to be tested to prevent the stone plastic floor from deforming from the sides, thereby indirectly improving the accuracy of subsequent laser testing.

[0031] Working principle: The control unit 3 controls the laser detection components A5 and B6 to detect the deformation of the SPC flooring. An industrial camera monitors the entire deformation detection process and transmits the images to the vision monitoring module 32. The model building module 33 then creates a scaled model. Activating the laser detection component B6, driven by the electric push rod B69, allows the laser sensor B68 to scribble horizontal lines on the surface of the SPC flooring. Driving the electric push rod A62 allows the laser sensor B68 to scribble vertical lines on the surface of the SPC flooring. The intersection of the vertical and horizontal lines is identified, thus determining the deformation value of the detection point. Finding multiple detection points on the SPC flooring surface improves detection accuracy. Simultaneously, synchronizing the laser scribing onto the scaled model allows for a more intuitive and rapid determination of the location of each detection point, facilitating the identification of deformation points and improving work efficiency. Secondly, during the testing process, the stone-plastic flooring to be tested is first placed on the placement plate 94, and then the placement plate 94 is moved into the main housing 1. During this movement, one end of the stone-plastic flooring will first contact the scraper 24, causing the scraper 24 to move upward, which will compress the gas in the sealing groove, thereby extending the pneumatic telescopic rod 261, and then causing the cleaning cotton 262 to move downward until the lower end of the cleaning cotton 262 contacts the upper surface of the placement plate 94. At this time, one side of the stone-plastic flooring will contact the side of the cleaning cotton 262. At this point, the placement plate 94 stops moving, and the process begins. The electric push rod D23 moves the top block 22 left and right, causing one side of the SPC flooring to move left and right on the surface of the cleaning cotton 262 for wiping. After wiping is completed, the placement plate 94 continues to move, causing the SPC flooring to push the cleaning cotton 262, which causes the pneumatic telescopic rod 261 to rotate until the SPC flooring passes through the cleaning cotton 262. At this time, the lower end of the cleaning cotton 262 will contact the upper surface of the SPC flooring, and then the upper surface of the SPC flooring will be wiped using the cleaning cotton 262. That is, the two surfaces of the SPC flooring to be tested can be cleaned by the cleaning cotton 262, improving the accuracy of the test.

[0032] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
