Description

Technical Field

[0001] The present invention relates to the technical field of plate detection, and specifically provides a plate detection device and method for building decoration and fitment. Background Art

[0002] Decorative board is a kind of artificial board. It is a thermosetting laminated plastic made of a variety of special papers after chemical treatment and high-temperature and high-pressure adhesives. After the decorative board is processed, it is necessary to detect the flatness of its surface through a plate detection device.

[0003] For example, a decorative board detection device for building decoration and fitment with the publication number CN116046064B realizes the control of the pressure detection component and the vertical and horizontal detection component through a switching component. Through the pressure detection component, the pressure detection of the decorative board is realized, ensuring the qualified rate and simple operation. Through the vertical and horizontal detection component, the verticality detection and flatness detection of the decorative board are realized. Through the switching component, it can assist in fitting during the fitting process of the decorative board.

[0004] When the existing plate detection device detects a plate, it needs to drive multiple groups of detection plates to move and contact the surface of the plate through a driving component, and then observe the positions of the multiple groups of detection plates. If the positions of the detection plates are uneven, it means that the surface of the plate is not flat. However, this detection method can only detect the local positions of the plate, making it difficult to detect the whole, prone to detection errors, and the detection range of the plate is also fixed, making it difficult to adjust according to the size of the plate. Before the flatness detection of the plate, its surface is not cleaned either. When there are sundries on the surface of the plate, it will interfere with the detector. Summary of the Invention

[0042] In specific implementation, for the building decoration sheet material detection device and its method, when detecting the flatness of the sheet material surface, the sheet material is placed on the detection rack 2, and then multiple hydraulic rods 3 are started to fix the sheet material. After the fixing is completed, the hydraulic rod 3 can be started to drive the connecting frame 6 to move downward. The connecting frame 6 can drive the moving frame 9 and multiple detection heads 10 at its bottom to move as well. When the detection head 10 touches the sheet material, it will move upward to squeeze the spring a12, and the spring a12 can squeeze the pressure sensor 13 at the top. When the pressure value detected by the pressure sensor 13 reaches the set value, a signal can be sent to the PLC controller. The PLC controller can control the hydraulic rod 3 to stop moving downward. At this time, the servo motor 7 can be started to drive the threaded rod a8 to perform a threaded drive with the moving frame 9, so that the moving frame 9 moves in the connecting frame 6. When the moving frame 9 moves, it can drive multiple detection heads 10 at the bottom to move on the top of the sheet material. At the same time, one end of the threaded rod a8 will drive the bevel gear a15 to engage with the bevel gear b16, thereby driving the bevel gear b16 and the rectangular rod 17 at its bottom to rotate. The rectangular rod 17 can drive the round rod 18 to rotate;

[0043] When the rectangular rod 17 moves up and down in the connecting frame 6, it will move inside the round rod 18 to adapt to the position of the connecting frame 6. The round rod 18 can drive the synchronous wheel a191 in the bottom transmission mechanism 19 to start rotating. The synchronous wheel a191 can drive the synchronous wheel b193 to rotate through the synchronous belt 192, so that the reciprocating motion mechanism 20 at its top starts to move. The toggle rod 201 in the reciprocating motion mechanism 20 will rotate following the synchronous wheel b193, and drive the rotating block 204 at one end of the top to slide in the through groove inside the connecting frame b205, thereby toggling the connecting frame b205 to drive the detection rack 2 and the sheet material at the top to move reciprocally. At this time, since multiple detection heads 10 perform a linear motion in one direction on the top of the sheet material, while the sheet material performs a reciprocating motion in another direction, the contact area between the detection head 10 and the sheet material will increase, thus completing a comprehensive detection of the flatness of the sheet material and improving the detection accuracy. When the size of the sheet material changes, the threaded rod b202 can be rotated to perform a threaded drive with the threaded block 203, thereby driving the threaded block 203 to move. The threaded block 203 can drive the rotating block 204 at the top to move inside the connecting frame b205. At this time, when the connecting frame b205 rotates one circle following the toggle rod 201, the reciprocating moving distance of the toggled connecting frame b205 will change. Therefore, the reciprocating moving distance of the sheet material will also change, which can adapt to the changes in the sizes of different sheet materials;

[0044] When the detection head 10 contacts the concave and convex parts on the surface of the plate, the detection head 10 will move, causing the compression state of the spring a12 to change, and the extrusion force on the pressure sensor 13 will also change. The changed pressure value will be transmitted to the external terminal. By analyzing the fluctuation of the value transmitted by the pressure sensor 13, the flatness of the plate surface can be detected. At the same time, in order to intuitively show the flatness of the plate surface, a marking mechanism 14 is set on both sides of the mobile frame 9. When the plate is flat, the marking pen b1412 and the marking pen b1412 are aligned. a148 will not contact the plate. When the detection head 10 contacts the protrusion on the surface of the plate, it will move upward. At this time, the detection head 10 will rotate the rotating rod 142 through the toggle block 141 on one side, so as to move the connecting frame a144 downward through the connecting pin 143 at one end, so that the tension spring 145 at the top is stretched. The connecting frame a144 can drive the connecting block a146 at the bottom to move downward, so that the marking pen a148 at the bottom contacts the plate. The marking pen a148 will leave a mark on the surface of the plate, indicating that there is a protrusion on one side.

[0045] The marking pen a148 can squeeze the spring b147, thereby moving in the connecting block a146 to prevent the bottom of the marking pen a148 from making hard contact with the plate when it moves down a large distance, causing damage to the marking pen a148. When the detection head 10 contacts the depression on the surface of the plate, the spring a12 will push the detection head 10 to move down. At this time, the detection head 10 can drive the marking pen b1412 to move down and contact the plate, leaving a mark on the plate, indicating that there is a depression on one side. The marking pen b1412 can also be retracted in the connecting block c1410 to prevent damage. The marking pen b1412 has a different color from the marking pen a148, so the protrusions and depressions on the plate can be distinguished. Through the above operation, the surface flatness of plates of different sizes can be comprehensively detected, so as to find defects on the plate and intuitively show the location and number of defects.

[0046] See also Figures 1 - 4 and Figures 7 - 10, one end of the horizontal plate at the bottom of the hydraulic rod 3 is fixedly connected to a connecting rod b23. The bottom of the connecting rod b23 is slidably connected to a rotating shaft 24. The outer side of the rotating shaft 24 is movably connected to a bracket 25 through a bearing. The top of the bracket 25 is fixedly connected to the top plate 4. One side of the bottom of the rotating shaft 24 is fixedly connected to a convex block 26, and one end of the convex block 26 is semi-circular; a spiral groove 27 is formed inside the rotating shaft 24, and the spiral groove 27 is slidably connected to the convex block 26. The spiral groove 27 is arranged in a complete circle, and one end of the spiral groove 27 is provided with a straight groove 28 which is formed inside the rotating shaft 24. The bottom of the rotating shaft 24 is fixedly connected to a connecting rod a29. One end of the connecting rod a29 is movably connected to a connecting rod b30 through a rotating shaft; one end of the connecting rod b30 is movably connected to a cleaning rod 31 through a rotating shaft. A scraping plate 32 is slidably connected inside the cleaning rod 31. The bottom of the scraping plate 32 is wedge-shaped. Both sides of the scraping plate 32 are fixedly connected to sliding blocks 33. The outer sides of the sliding blocks 33 are slidably connected to the cleaning rod 31. Both ends of the cleaning rod 31 are slidably connected to sliding rods 34. Both ends of the sliding rods 34 are fixedly connected to the top of the machine body 1; one side of the detection frame 2 is fixedly connected to a spring d35. One end of the spring d35 is fixedly connected to a limiting rod 36. One end of the limiting rod 36 is fixedly connected to a connecting plate 37. One side of the connecting plate 37 abuts against the detection frame 2. The outer shape of the connecting plate 37 is "L"-shaped. The outer side of the limiting rod 36 is slidably connected to the detection frame 2. A moving groove matching the sliding block 33 is formed inside the cleaning rod 31. The sliding block 33 and the cleaning rod 31 form a sliding structure.

[0047] During specific implementation, for the building decoration and finishing board detection device and its method, when the hydraulic rod 3 drives multiple groups of detection heads 10 to contact the board, it can also drive the connecting rod b23 to move. The connecting rod b23 will move inside the rotating shaft 24 and slide through the convex block 26 on one side of the bottom in the spiral groove 27 inside the rotating shaft 24, thereby driving the rotating shaft 24 to rotate. When the convex block 26 breaks away from the spiral groove 27 and enters the straight groove 28, the rotating shaft 24 will rotate a complete circle and stop rotating after the convex block 26 enters the straight groove 28. When the rotating shaft 24 rotates, it can drive the connecting rod a29 and the connecting rod b30 at the bottom to rotate, thereby pushing the cleaning rod 31 at one end to slide on the outer side of the sliding rod 34 and perform a reciprocating movement. Due to the length setting of the spiral groove 27, the detection head 10 will not contact the cleaning rod 31 before the reciprocating movement ends;

[0048] When the cleaning rod 31 moves, it will drive the scraper 32 at the bottom to move together. The scraper 32 will first contact the plate through the inclined surface at the bottom, and then move upward and slide in the cleaning rod 31. When it crosses the plate, the inclined surface will contact the connecting plate 37, and then slide in the cleaning rod 31 again. The connecting plate 37 can prevent the scraper 32 from moving down to the bottom of the plate when it moves to the edge of the plate, resulting in inability to reset. When the scraper 32 moves back to its original position, it will move down to the top of the plate again. At this time, the scraper 32 will contact the sundries on the top of the plate through the straight surface. Therefore, at this time, the scraper 32 will not slide upward in the cleaning rod 31, but will scrape up the sundries adhered to the surface of the plate and push them to the gap on one side of the detection rack 2, completing the cleaning of the sundries on the surface of the plate and maintaining the accuracy of the plate during detection. The connecting plate 37 can move in the detection rack 2 through the slide bar 34 on one side and squeeze the spring d35 to adapt to plates of different sizes. In this way, through the above operations, the sundries on the surface of the plate can be scraped and cleaned to prevent these sundries from interfering with the detection results during detection.
