The Chinese invention patent with application number CN108592770B discloses a square wood board flatness detection device. When in use, the wood board and the horizontal board slide relative to each other. By observing whether the horizontal board floats, it can be seen whether the surface of the wood board is horizontal. The operation is simple and the detection efficiency is high.

[0003] When the depression on the surface of the wooden board is smaller than the area of ​​the horizontal board, the horizontal board will be unable to descend, resulting in the inability to detect the uneven area. If the above problem is solved by reducing the area of ​​the horizontal board, then the number of times the horizontal board is moved will need to be increased to cover the wooden board to be inspected, resulting in low detection efficiency, so further improvement is needed.

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1-Figure 4 The invention shows a flatness detection device for processing artificial boards, comprising an outer frame 1, a carrier plate 2 is fixedly connected to the inner wall in the middle of the bottom end of the outer frame 1, a board to be inspected 3 is placed on the top of the carrier plate 2, an electric guide rail 4 is fixedly connected to the inner wall at the top end of the outer frame 1, an electric telescopic rod 5 is fixedly connected to one end of the electric guide rail 4, a mounting frame 6 is fixedly connected to the output end of the electric telescopic rod 5, an air frame 7 is fixedly connected to the bottom end of the mounting frame 6, a sealing ring 8 is fixedly connected to the edge of the bottom end of the air frame 7, an air pipe 9 is fixedly connected to the inner wall on one side of the mounting frame 6, and the bottom end of the air pipe 9 and the air frame 7 are fixedly connected. A connecting pipe 10 is connected, the inner wall of the air pipe 9 is sealingly and slidably connected with a piston 11, the top of the piston 11 is fixedly connected with a linkage rod 13, the inner wall of the mounting frame 6 is slidably connected with an active rack 14 and a passive rack 15, the inner wall of the mounting frame 6 located between the active rack 14 and the passive rack 15 is rotatably connected with two intermediate gears 16, the two intermediate gears 16 are meshed with each other and respectively meshed with the active rack 14 and the passive rack 15, the inner wall of the bottom end of the mounting frame 6 is fixedly connected with a distance sensor 12, and the distance sensor 12 is located directly below the passive rack 15.

[0026] When inspecting the plate 3 to be inspected, the sealing ring 8 is made to fit with the surface of the plate 3 to be inspected, and the electric guide rail 4 drives the air frame 7 to move along the surface of the plate 3 to be inspected. When the air frame 7 moves to the raised position of the plate 3 to be inspected, the space inside the air frame 7 is compressed and the pressure increases. At this time, the piston 11 moves upward, and drives the passive rack 15 to move downward through the active rack 14 and the intermediate gear 16. When the air frame 7 moves to the recessed position of the plate 3 to be inspected, the space inside the air frame 7 increases and the pressure decreases. At this time, the piston 11 moves downward, and drives the passive rack 15 to move upward through the active rack 14 and the intermediate gear 16. The moving distance of the passive rack 15 is obtained by the distance sensor 12, and the surface flatness of the plate 3 to be inspected can be calculated. The above arrangement can detect uneven states of different sizes on the plate 3 to be inspected while ensuring the detection efficiency, thereby improving the accuracy of the detection of the plate 3 to be inspected.

[0027] The diameter of the intermediate gear 16 meshing with the active rack 14 is greater than the diameter of the intermediate gear 16 meshing with the passive rack 15. Through the above arrangement, the moving distance of the active rack 14 can be magnified, so that the active rack 14 can drive the passive rack 15 to move a large distance when moving a small distance, thereby improving the measurement accuracy of the distance sensor 12.

[0028] The inner wall of the outer frame 1 at one end of the bearing plate 2 is fixedly connected with a reset seat 17, and the top surface of the reset seat 17 is flush with the top surface of the plate to be inspected 3. Through the above arrangement, before the air frame 7 moves onto the plate to be inspected 3, the air frame 7 is placed on the reset seat 17, which can calibrate the air pressure in the air frame 7.

[0029] The inner wall of the outer frame 1 at the other end of the carrying plate 2 is slidably connected with a self-test seat 18, the top surface of the self-test seat 18 is flush with the top surface of the board to be tested 3, and the bottom end of the self-test seat 18 is fixedly connected with a bottom block 19. The inner wall of the outer frame 1 close to the bottom block 19 is fixedly connected with a driving frame 20, and a screw rod 21 is rotatably connected between the two ends of the driving frame 20, and the screw rod 21 penetrates the bottom block 19 and is threadedly connected thereto. When the screw rod 21 is rotated, the self-test seat 18 can be driven to rotate left and right, and the reset seat 17 is cooperated to clamp or release the board to be tested 3. At the same time, the air frame 7 moves on the reset seat 17 and the board to be tested 3 and then moves to the surface of the self-test seat 18. The positions of the passive rack 15 on the reset seat 17 and the self-test seat 18 can be compared to determine whether the air frame 7 leaks when moving on the board to be tested 3. It can play a self-test role in the flatness detection of the board to be tested 3, and improve the accuracy of the equipment detection results.

[0030] The second implementation method:

[0031] Figure 1-Figure 7A flatness detection device for artificial board processing is shown. Different from the first embodiment, the outer frame 1 is fixedly connected to the side of the reset seat 17 and the side of the outer frame 1 located at the self-inspection seat 18 with electric lifting rods 22, and the telescopic ends of the two electric lifting rods 22 are fixedly connected with cross bars 23, and a sliding membrane 24 is fixedly connected between the two cross bars 23. Through the expansion and contraction of the cross bars 23, the sliding membrane 24 can be driven to be spread flat on the surfaces of the reset seat 17, the board to be inspected 3 and the self-inspection seat 18, and lubricating oil is sprayed on the surface of the sliding membrane 24. At this time, when the air frame 7 moves along the reset seat 17, the board to be inspected 3 and the self-inspection seat 18, the friction of the sealing ring 8 can be reduced, the sealing effect of the air frame 7 can be increased, and the rough surface of the board to be inspected 3 can be detected, thereby improving the detection effect and increasing the detection types of the board to be inspected 3.

[0032] The sliding film 24 is configured as a double-layer transparent material, and the two sliding films 24 are provided with a photochromic coating on the sides close to each other. The inner wall of the middle part of the air frame 7 is fixedly connected with an ultraviolet lamp 25, and the ultraviolet lamp 25 is electrically connected to the distance sensor 12.

[0033] Through the above arrangement, when the distance sensor 12 detects that the passive rack 15 moves up and down, it sends an electrical signal to the ultraviolet lamp 25 to start it. When the ultraviolet lamp 25 is started, it irradiates the photochromic layer to change its color. At this time, the staff can obtain the deformation position of the board to be inspected 3 based on the color change of the slip film 24, which is convenient for the subsequent processing of the board to be inspected 3. When the photochromic layer stops irradiating for a period of time, it returns to its original color.

[0034] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
