Description

Technical Field

[0001] This invention relates to the field of laser measurement technology for wood, specifically to a laser measurement device for wood processing. Background Technology

[0002] In actual wood processing and manufacturing, such as with multi-layer solid wood boards, the temperature and humidity of each layer of wood veneer affect the bonding process. After high-temperature and high-pressure bonding, residual stress remains inside the multi-layer veneer, especially in long, narrow sheets, where curved bending is easily observed along its length. After hot-pressing, multi-layer solid wood boards require warpage measurement to remove boards with excessive dimensional deviations. The boards are then corrected before being used in subsequent processing such as slitting. Current laser measuring equipment typically places the board on a measuring table and then measures the warpage using a laser. When measuring warp using a distance measuring instrument, if a long strip of solid wood plywood that has warped is placed on the measuring table, for example, if both ends are upturned, the height of the upturn will be greatly reduced under the weight of the ends, and it may even completely adhere to the measuring table. Similarly, if the middle is upturned, it is also easy for the middle to adhere to the measuring table under its own weight, leading to missed detections in subsequent flatness measurements. It is also inconvenient to adjust the support force on both ends of the board, increasing the missed detection rate. There is also a method of measuring the warp by vertically clamping the board, but this method causes greater damage to the board.

[0003] Therefore, we propose a laser measuring device for wood processing. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention employs a measuring device to achieve lateral measurement of board warpage, providing a more comprehensive inspection and allowing staff to intuitively understand the warpage deviation. The use of a reference adjustment control allows for adjustable support compensation for long, large boards, ensuring consistent support force for each measured board and guaranteeing a consistent testing benchmark. This better reflects the board's warpage, avoiding the limitations of traditional measuring platforms where, when the board warps upwards at both ends, it naturally falls under its own weight, reducing the warpage and resulting in smaller height reading deviations or even missed warpage measurements. This structure automatically detects the pressure at both ends of the support half; if the board warps, it can promptly compensate for the support, amplifying the warpage error and reducing the missed detection rate. The structure is simple and allows for automatic control and compensation adjustment.

[0019] The use of position monitoring devices makes it easier for staff to adjust the placement of the boards, preventing them from being misplaced beyond the standard. At the same time, the use of infrared position switches can further monitor the positional accuracy of the boards and maintain measurement accuracy.

[0020] The structure employs adjustable support components and magnetically controllable retraction. When the position monitoring component detects excessive deviation of the sheet material, it can automatically control the push column to move downward and retract, changing the support force on the sheet material. After retraction, it will interfere with the measurement results of the laser rangefinder, which can alert the staff. At the same time, this structure uses a support spring to support the push column, which can prevent the sheet material from falling hard or hitting the push column during loading and unloading, thus avoiding instantaneous squeezing damage to the pressure sensor.

[0036] The measuring mounting component 1 further includes: a display 103 and a support platform 104. The display 103 is fixedly mounted on the measuring platform 102; the support platform 104 is fixedly mounted in the middle of the measuring platform 102; the support platform 104 is used to support the middle of the wooden board; the edges of the support platform 104 are chamfered; the display 103 is used to display measurement data; the measuring device 2 includes: a drive screw 201, a drive motor 2011, a moving frame 202, a slider 2021, and a protective cover 203. Two drive screws 201 are rotatably mounted on the measuring platform 102; two drive motors 2011 are fixedly mounted on the measuring platform 102, and the two drive motors 2011... A drive screw 201 is fixedly mounted on the output shaft; a movable frame 202 is located above the measuring platform 102; sliders 2021 are fixedly mounted on both sides of the bottom of the movable frame 202, and the two sliders 2021 are slidably mounted in two grooves on the measuring platform 102; two drive screws 201 are threadedly connected to the two sliders 2021; a protective cover 203 is fixedly mounted on the movable frame 202; the measuring device 2 also includes: a controller 204 and a laser rangefinder 205, the controller 204 is fixedly mounted on the protective cover 203; a row of laser rangefinders 205 is fixedly mounted on the movable frame 202, and the row of laser rangefinders 205... The detection ends pass through the movable frame 202 respectively; the display 103 is electrically connected to a row of laser rangefinders 205; the reference adjustment control 3 includes: an electric cylinder mounting bracket 301, a drive electric cylinder 302 and a pressure sensor 303, the electric cylinder mounting bracket 301 is fixedly mounted on the bottom of the measuring platform 102 by bolts; the drive electric cylinder 302 is fixedly mounted on the electric cylinder mounting bracket 301; the output shaft of the drive electric cylinder 302 passes through the electric cylinder mounting bracket 301; the pressure sensor 303 is fixedly mounted on the output shaft of the drive electric cylinder 302; the controller 204 is electrically connected to the drive electric cylinder 302 and the pressure sensor 303; the reference adjustment control 3 also includes: a sliding sleeve 304 and a connecting... The measuring platform 102 is equipped with two sliding sleeves 304, each slidably mounted on the measuring platform 102. The two sliding sleeves 304 are symmetrically arranged and pass through the measuring platform 102. A connecting block 305 is fixedly mounted at the bottom of each sliding sleeve 304, and the connecting block 305 is located inside the electric cylinder mounting bracket 301. The driving electric cylinder 302 is used to push and adjust the support height of the sliding sleeves 304. The measuring device 2 allows for lateral measurement of the board warpage, providing a more comprehensive inspection and enabling staff to intuitively understand the warpage deviation. Furthermore, this structure uses laser measurement, which does not contact the board, resulting in less interference.Using a reference adjustment control unit 3, adjustable support compensation can be provided for long, large-area boards, ensuring consistent support force for each measured board and guaranteeing consistent detection benchmarks. This allows for a better reflection of the board's warpage, avoiding the pitfalls of traditional measurement platforms. Traditional platforms prevent this by preventing board warpage when the ends are upturned, causing them to fall under their own weight and even completely adhere to the measurement platform. Similarly, traditional platforms prevent warpage when the middle of the board is arched and the ends are bent downwards, causing the middle section to press against the platform under its own weight. These issues reduce warpage, resulting in smaller deviations in height readings and potentially missed warpage measurements. This structure automatically detects the pressure at both ends of the support half. If the board warps, it compensates for the warpage in a timely manner, improving the accuracy of the true warpage and reducing measurement errors caused by weight, thus lowering the missed detection rate. The structure is simple, allowing for automatic control and compensation adjustment. Only one calibration is required, ensuring measurement accuracy throughout. No manual clamping of the board is needed, preventing damage.

[0037] The position monitoring component 4 includes: a monitoring mounting block 401 and a guide drag-reducing wheel 402. Four monitoring mounting blocks 401 are fixedly mounted on the measuring platform 102 by bolts, and the four monitoring mounting blocks 401 are symmetrically arranged. A right-angled groove is provided on the inner side of each monitoring mounting block 401. A guide drag-reducing wheel 402 is rotatably mounted on each monitoring mounting block 401. The guide drag-reducing wheel 402 is used to prevent excessive wear on the wooden board. Gaps are left between the right-angled grooves on the inner sides of the four monitoring mounting blocks 401 and the four sides of the wooden board. The position monitoring component 4 also includes: an infrared position switch 403. Two infrared position switches 403 are fixedly mounted on each monitoring mounting block 401. The two infrared position switches 403... A gap is left between the laser emission point and the edge of the right-angled groove on the inner side of the monitoring mounting block 401; the infrared position switch 403 is connected to an external relay; the infrared position switch 403 can directly power the relay; the use of the position monitoring component 4 facilitates the adjustment of the board placement position by the staff, avoiding excessive deviation of the board placement. At the same time, the use of the infrared position switch 403 can further monitor the position accuracy of the board, keeping the board inside the four monitoring mounting blocks 401, and the four sides of the board do not touch the inner side of the monitoring mounting blocks 401. This avoids friction when the board is pressed against the inner side of the monitoring mounting blocks 401. If the contact is too tight, it will directly affect the detection accuracy of the pressure sensor 303.

[0038] The control support component 5 includes: an electromagnet 501, an electromagnetic spindle 502, and a push column 503. Two electromagnets 501 are provided, and the two electromagnets 501 are respectively fixedly installed on both sides of the bottom of the connecting block 305. Electromagnetic spindles 502 are slidably sleeved on two sliding sleeves 304 respectively. Push columns 503 are slidably sleeved on two sliding sleeves 304 respectively. The bottom of the push column 503 is fixedly connected to the electromagnetic spindle 502. The two electromagnetic spindles 502 pass through the two electromagnets 501 respectively. The top of the push column 503 has an arc-shaped structure. When the electromagnet 501 magnetically attracts the electromagnetic spindle 502, the push column 503 retracts to below the support platform 104. The relay external to the infrared position switch 403 is electrically connected to the electromagnet 501. The control support component 5 also includes: a support spring 504, on which a support spring is sleeved on each of the two sliding sleeves 304. Support springs 504; one end of each support spring 504 is fixedly connected to the bottom of the two push columns 503, and the other end of each support spring 504 is fixedly connected to the inner side of the two sliding sleeves 304 respectively. An adjustable support component 5 is used, and through a magnetically controllable retraction structure, when the position monitoring component 4 detects excessive deviation of the plate material, it can automatically control the push columns 503 to move downwards and retract, changing the support force on the plate material. After retraction, it will interfere with the measurement results of the laser rangefinder 205, which can alert the operator. Simultaneously, this structure uses support springs 504 to support the push columns 503, which can prevent the plate material from falling hard or impacting the push columns 503 during loading and unloading, thus avoiding instantaneous compression damage to the pressure sensor 303 and causing accuracy drift. The structure is more reasonable and can ensure the service life of the pressure sensor 303.

[0039] The working principle of this embodiment is as follows: Before the formal use of this structure, a standard flat plate can be placed on the support platform 104, with both ends placed on the push columns 503. The sliding sleeve 304 is driven upward by the drive cylinder 302 to support the standard plate until the plate surface is flat again. The pressure of the pressure sensor 303 is the reference for the support pressure when measuring the plate of the current specification. When measuring the plate, the plate is placed on the support platform 104, with both ends placed on the push columns 503. The guide drag-reducing wheels 402 can be used to facilitate sliding the plate on the two guide drag-reducing wheels 402, saving effort. After the sheet metal is placed on the support platform 104, manual fine-tuning is required to maintain a gap between the four corners of the sheet metal and the inner side of the monitoring mounting block 401. This prevents the edges of the sheet metal from pressing against the inner side of the monitoring mounting block 401, which could interfere with the pressure detection of the subsequent pressure sensor 303. Simultaneously, the basic installation position must be maintained correctly. At this point, the four corners of the sheet metal should block the infrared position switch 403. The infrared position switch 403 can then control the electromagnet 501 to de-energize via a relay, preventing it from magnetically attracting the electromagnetic spindle 502. Under the elastic push of the support spring 504, the push column 503 will elastically extend. When the plate is pressed against the bottom, both ends of the plate bend downwards under their own weight, pressing down on the sliding sleeve 304. This causes the connecting block 305 to compress the pressure sensor 303. The pressure sensor 303 can monitor the pressure in real time. If both ends of the plate are warped upwards, the pressure exerted on the pressure sensor 303 by the plate ends will be less than the downward pressure exerted on the pressure sensor 303 by the ends of a flat plate. This controls the drive cylinder 302 to push the pressure sensor 303 upwards, causing the sliding sleeve 304 to move upwards and push against both ends of the plate. At this time, the pressure on the pressure sensor 303 will gradually increase. The baseline is to achieve the pressure at both ends of the flat plate. Similarly, if there is downward warping at both ends of the plate, the initial pressure on the pressure sensor 303 at both ends of the plate will be relatively large. It is necessary to control the sliding sleeve 304 to move down for adjustment. After the above adjustment, the warping deformation of the plate will be amplified, which can better match the actual curvature. Then, control the drive motor 2011 to drive the drive screw 201 to rotate, and the threaded drive slider 2021 to drive the moving frame 202 to move, which will drive a row of laser rangefinders 205 to move above the plate to measure the horizontal height. The reading is displayed on the display 103.

[0040] During the measurement process, if the plate offset exceeds the standard due to shaking, initial placement deviation of the plate, or large adjustment range of the plate support by the electric cylinder 302 in the early stage, and the plate shifts within the four monitoring mounting blocks 401, causing an increase in the gap between the monitoring mounting blocks 401 and the edges of the plate, the infrared position switch 403 at the corresponding position can automatically detect the absence of obstructions and the significant increase in distance. At this time, the infrared position switch 403 can control the electromagnet 501 to be energized through the relay, and the electromagnetic spindle 502 is magnetically attracted again. The electromagnetic spindle 502 can then move down again, compressing the support spring 504. At this time, the push column 503 can move down, and the support height of the push column 503 on the plate changes. The plate will bend under its own weight, causing the measurement reading to be distorted. The staff needs to make timely adjustments.
