Description

Technical Field

[0002] Testing the flatness of particleboard is a key step in ensuring its quality. Traditional testing methods are inefficient and easily affected by human factors. Laser testing technology uses a laser scanner to scan the surface of particleboard to obtain high-precision three-dimensional point cloud data, which can quickly and accurately detect tiny unevenness. Its advantages lie in its fast testing speed, high accuracy, and the ability to achieve automated operation, effectively improving testing efficiency.

The outer surface of the board is scanned by the laser detector for detection to detect tiny unevenness or defects, and the two sides of the board are abutted against the outer surface of the rotating wheel. When the board becomes uneven, the buffer telescopic rod is moved left and right by the action of the first spring, so that the first abutting rod and the second abutting rod can touch the second pressure sensor and the first pressure sensor, thereby detecting the unevenness on both sides, achieving reliable detection results, and reducing the false alarm rate.

[0004] Although the above-mentioned device can detect uneven conditions on both sides when in use, if there are bulges in the middle or on both sides of the wooden board, the distance set between the wooden board and the laser detector will deviate, resulting in changes in the reference system and the angles of laser emission and reception, causing errors in the detection data of the laser detector.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0020] like Figures 1 to 3 As shown, a surface flatness detection device based on particleboard processing according to an embodiment of the present invention includes a base 1, a plurality of conveying rods 11 are provided on the side of the base 1, a wooden board 12 is placed on the conveying rods 11, a detection box 13 is fixedly installed on the top of the base 1, a laser detector 14 is fixedly installed at the top center of the detection box 13, and the laser detector 14 is used to detect the flatness of the surface of the wooden board 12, and a detection auxiliary device 2 is fixedly installed on the side of the base 1 located below the detection box 13, and a grinding device 3 is provided on the detection auxiliary device 2, and the detection auxiliary device 2 is used to transport and adjust the level of the wooden board 12; like Figures 4 to 6 As shown, the detection auxiliary device 2 includes a clamping member 21, a lifting member 22, and a leveling member 23. The clamping member 21 is used to clamp the wooden board 12. The leveling member 23 includes a leveling detection plate 233. The leveling detection plate 233 contacts the side of the wooden board 12. The leveling detection plate 233 is tilted to drive the lifting member 22 to rotate, so that the clamping member 21 adjusts the wooden board 12 to a horizontal position.

[0021] It should be noted that after the production of particleboard is completed, its flatness needs to be tested. When using laser to test the flatness, the particleboard needs to be kept horizontal. However, during the testing and transportation process, if there are bulges on the surface or edge of the particleboard, it may shake during transportation. Therefore, it cannot keep the horizontal surface upward and may shake during transportation. Such particleboards cannot pass the test and are generally transported directly to the waste area. The cause of bulges and uneven flatness is not necessarily a problem of the entire board being tilted. It may be that only the edge or part of the board is uneven. If the uneven part that can be cut is removed, the particleboard can still be used. For this reason, the following improvements have been made to the detector; First, place the wooden board 12 (the wooden board 12 in this article refers to the particle board) on the conveying rod 11 at equal intervals, start the conveying rod 11 to rotate and convey the wooden board 12, and the conveying rod 11 conveys the wooden board 12 to the inside of the detection box 13. The detection auxiliary device 2 and the grinding device 3 are installed in the middle position of the laser detector 14. The wooden board 12 first contacts the grinding device 3 to clean the side of the wooden board 12, and then is transported toward the detection auxiliary device 2. In the initial state, the two rollers 213 provided on the clamping member 21 are in contact with each other, and the laser detector 14 is started. When the wooden board 12 passes by, the two rollers 213 move away from each other, thereby clamping the wooden board 12, completing the clamping effect of the clamping member 21. When the top edge of the wooden board 12 is located on the moving path of the roller 213 and a bulge appears, the two rollers 213 move away from each other and always keep the clamp at the center of the thickness of the wooden board 12. If a bulge appears on the top of the wooden board 12, the wooden board 12 The position of the thickness center of 12 changes, so the thickness center of the wooden board 12 moves upward, and the wooden board 12 moves upward relative to the initial position of the clamping member 21. The wooden board 12 drives the upper part of the leveling detection plate 233 to move away from the base 1, and the lower part of the leveling detection plate 233 moves toward the base 1, thereby driving the lifting member 22 to move and rotate. The lifting member 22 causes the clamping member 21 to move downward, and the position of the clamping member 21 can be adjusted, so that the top of the wooden board 12 is horizontal, preventing the wooden board 12 from tilting and causing a decrease in detection accuracy, reducing detection errors, until the wooden board 12 passes over the protrusion, the clamping member 21 maintains the original clamping position, under the action of the leveling detection plate 233, the clamping member 21 and the leveling member 23 are reset to the original clamping state, and the clamping member 21 without the protrusion on the other side is always in a horizontal position, thereby completing the detection, until the second wooden board 12 enters again, the detection can be continued.

[0022] like Figures 4 and 5As shown, the clamping member 21 includes a lifting block 215 slidably mounted on the base 1, a first gear 214 is rotatably mounted inside the lifting block 215, two symmetrically arranged rack blocks 211 are slidably mounted inside the first gear 214, a first protrusion 212 is fixedly mounted on the rack block 211, a roller 213 is rotatably mounted inside the first protrusion 212, the roller 213 is used to clamp the wooden board 12, and the lifting block 215 is raised and lowered to adjust the horizontal position of the wooden board 12.

[0023] It should be noted that since the clamping member 21 needs to clamp the wooden board 12 when in use, the rack block 211, the first protrusion 212 and the roller 213 are slidably installed inside the lifting block 215, and the installation positions of the first gear 214 and the lifting block 215 are provided with torsion springs, so that the two rollers 213 have a force to approach each other, thereby achieving the effect of clamping the wooden board 12 when the wooden board 12 is transported.

[0024] like Figures 4 to 6 As shown, the lifting member 22 includes a first rotating block 221 rotatably mounted inside the lifting block 215, a half gear 222 is fixedly mounted on the side of the first rotating block 221, a first limiting rod 228 is fixedly mounted on the side of the half gear 222, a tooth 223 and a first fixed block 224 are fixedly mounted on the side wall of the base 1 close to the wooden board 12, a first sliding rod 225 is fixedly mounted inside the first fixed block 224, a slider 227 is slidably mounted on the outer wall of the first sliding rod 225, and first springs 226 are symmetrically mounted on both ends of the slider 227, the first springs 226 keep the slider 227 in the middle position of the first sliding rod 225, a groove is provided on the slider 227, so that the first limiting rod 228 slides inside the slider 227, the half gear 222 is engaged with the tooth 223, and a leveling member 23 is provided on the side wall of the first rotating block 221, which contacts the wooden board 12 and is used to adjust the position of the lifting block 215.

[0025] It should be noted that when the leveling detection plate 233 on the leveling member 23 contacts the side of the wooden board 12, if the leveling detection plate 233 is offset, it can drive the first rotating block 221 to rotate, and the rotation of the first rotating block 221 can drive the half gear 222 to rotate, and the half gear 222 is engaged with the teeth 223, so the position of the lifting block 215 sliding inside the base 1 can be adjusted to achieve a leveling effect, and a first limiting rod 228 is provided on the half gear 222, and a slider 227 is provided on the outside of the first limiting rod 228. The slider 227 slides on the outer wall of the first slide rod 225, and a first spring 226 is provided on both sides of the slider 227, so that the first limiting rod 228 is in the middle position of the half gear 222 in the normal state, which plays the role of adjusting the angle of the leveling detection plate 233, thereby adjusting the height of the lifting block 215, so that the wooden board 12 is in a horizontal position to improve the detection accuracy.

[0026] like Figure 7 As shown, the leveling member 23 includes a second sliding rod 231 fixedly mounted on the side of the first rotating block 221, and a leveling detection plate 233 is slidably mounted on the end of the second sliding rod 231.

[0027] It should be noted that a second slide rod 231 is slidingly provided inside the leveling detection plate 233, so that when the wooden board 12 passes and the wooden board 12 is tilted, it can adapt to the width change of the wooden board 12 and adjust the position and level of the wooden board 12.

[0028] like Figure 7 As shown, the grinding device 3 includes a U-shaped block 31 fixedly mounted on the end of the leveling detection plate 233, a grinding rod 32 is rotatably mounted inside the U-shaped block 31, a cleaning brush 33 is provided on the side of the U-shaped block 31, and the cleaning brush 33 is used to clean the surface of the grinding rod 32, and a second limiting rod 34 is fixedly mounted on the top of the U-shaped block 31.

[0029] It should be noted that a torsion spring is provided at the connection position between the leveling detection plate 233 and the U-shaped block 31. Although the grinding rod 32 and the U-shaped block 31 are rotationally connected, there is friction between the U-shaped block 31 and the grinding rod 32. Therefore, when the grinding rod 32 contacts the side of the wooden board 12, although the grinding rod 32 will rotate with the wooden board 12, it can also grind the side of the wooden board 12 to prevent burrs from being generated, causing a gap to appear at the connection position between the leveling detection plate 233 and the wooden board 12, and the cleaning brush 33 can clean the surface of the grinding rod 32, thereby improving the grinding effect.

[0030] like Figure 7As shown, a torsion spring is provided at the connection position between the leveling detection plate 233 and the U-shaped block 31 , so that the U-shaped block 31 has a force to rotate toward the middle of the leveling detection plate 233 .

[0031] It should be noted that a torsion spring is provided at the connection position between the leveling detection plate 233 and the U-shaped block 31, so that the U-shaped block 31 has the force to rotate toward the middle of the leveling detection plate 233, so that the second limit rod 34 on the U-shaped block 31 is in contact with the side of the leveling detection plate 233 under normal conditions.

[0032] like Figure 5 As shown, a torsion spring is provided at the installation position of the first gear 214 and the lifting block 215 so that the two rollers 213 have a force to move closer to each other.

[0033] It should be noted that a torsion spring is provided at the installation position of the first gear 214 and the lifting block 215 so that the two rollers 213 have a force to move closer to each other, so that the two rollers 213 are in contact with each other when not clamped.

[0034] like Figure 4 As shown, the center height of the first gear 214 is kept at the same height as the thickness center of the wooden board 12 .

[0035] It should be noted that the center height of the first gear 214 is kept at the same height as the thickness center of the wooden board 12 , so that the wooden board 12 can be kept in a horizontal position in the clamped state when detecting the flatness of the wooden board 12 .

[0036] like Figure 7 As shown, one end of the leveling detection plate 233 is provided with an inclination angle for contacting the side of the wooden board 12 .

[0037] It should be noted that one end of the leveling detection plate 233 is provided with an inclination angle for contacting the side of the wooden board 12 to prevent the leveling detection plate 233 from getting stuck on the wooden board 12 .

[0038] like Figure 6 As shown, the elastic forces provided by the two first springs 226 remain the same, so that the slider 227 is located at the center of the first slide rod 225 .
