Description
Technical Field
[0001] This invention relates to the field of wood flooring repair technology, specifically to intelligent control repair and shaping equipment and method for defects on the surface of raw wood flooring. Background Technology
[0002] Wood flooring refers to flooring made of wood. Wood flooring produced in China is mainly divided into six categories: solid wood flooring, engineered wood flooring, multi-layer composite flooring, bamboo flooring, and cork flooring, as well as the emerging wood-plastic composite flooring.
[0003] For example, the national authorized patent announcement number CN214163360U discloses a wood floor scratch repair device, including a main body. Two screw caps are provided on the upper outer surface of the main body. Wheels are rotatably connected to both sides of the main body. Two fixing frames are provided on the front outer surface of the main body, and support rods are provided on the inner sides of each fixing frame. The other ends of the two support rods are rotatably connected to the upper outer surface of a scraper. A second spring is fixedly connected to the upper outer surface of the scraper, and a spring rod is provided at the other end of the second spring. One end of the spring rod is fixedly connected to the front outer surface of the main body. A self-locking lifting mechanism is fixedly connected to the rear outer surface of the main body, and a placement mechanism is placed on the front outer surface of the main body. This wood floor scratch repair device, through its placement mechanism and self-locking lifting mechanism, is more convenient and has a better prospect for use.
[0004] However, the aforementioned wood floor scratch repair equipment cannot automatically detect dents or areas that need repair during the floor repair process and automatically fill them with repair material. This can easily lead to omissions and incomplete repairs. Furthermore, after filling with repair material, it cannot smooth out the repaired dents or cracks, resulting in poor repair results. Summary of the Invention
[0005] The purpose of this invention is to provide a device and method for intelligent control, repair and shaping of defects on the surface of unfinished wood flooring, in order to solve the problem mentioned in the background art that the floor repair process cannot automatically detect pits or areas that need repair and automatically fill them with repair material.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A smart control and repair device for surface defects of unfinished wood flooring includes: a support frame, on the upper surface of which a first U-shaped frame is fixedly installed, and multiple sets of support wheels are rotatably installed inside the first U-shaped frame. A crossbar is fixedly installed on the upper surface of the support frame, and two sets of transmission mechanisms are slidably installed on the outer surface of the crossbar. The two sets of transmission mechanisms can slide synchronously inward or outward on the outer surface of the crossbar to change the distance between them to adapt to wood flooring of different sizes, so that the two sets of transmission mechanisms can contact the two sides of the wood flooring and move on the outer surface of the support wheels.
[0008] The support frame has two sets of connecting plates fixedly installed on its upper surface. A second U-shaped frame is rotatably installed between the two sets of connecting plates. The second U-shaped frame rotates around the upper periphery of the transmission mechanism via the connecting plates. A laser scanner is fixedly installed at one end of the second U-shaped frame. The laser scanner can tilt towards the support wheel through the rotation of the second U-shaped frame, enabling the laser scanner to perform high-frequency scanning of the wood floor surface through laser scanning. The scan data is converted into digital signals and sent to the controller, so that the controller can fully perceive the surface flatness of the wood floor.
[0009] The support frame has a suspended rod fixedly installed at the other end of its upper surface. The suspended rod is suspended above the outer periphery of the transmission mechanism. A repair mechanism is fixedly installed on the upper surface of the suspended rod. The repair mechanism is controlled by a controller. After receiving the floor defect signal sent by the laser scanner, the controller will control the repair mechanism to move laterally to the corresponding position and vertically downward to spray repair material onto the surface of the wooden floor and scrape it into the corresponding pit. The laser scanner and controller are Leica RTC360 and Leica Cyclone Field 360, respectively.
[0010] Preferably, a wing bolt is threaded onto one end of the connecting plate, so that the wing bolt can press against one end of the second U-shaped frame, thereby enabling the position of the second U-shaped frame to be locked by the pressing of the wing bolt after the angle of the second U-shaped frame is adjusted.
[0011] Preferably, the transmission mechanism includes two sets of third U-shaped frames. Sliding sleeves are fixedly installed on the lower surfaces of the two sets of third U-shaped frames. The two sets of third U-shaped frames are slidably installed on the outer surface of the crossbar through the sliding sleeves, and the two sets of third U-shaped frames are arranged opposite to each other. Two sets of transmission columns are rotatably installed inside the third U-shaped frames. Transmission belts are fitted on the outer surfaces of the two sets of transmission columns. A motor is fixedly installed on the upper surface of the third U-shaped frames. The output shaft of the motor passes through the third U-shaped frames and is fixedly connected to one of the transmission columns. This allows the two sets of third U-shaped frames to drive the transmission belt to contact both sides of the wooden floor and be moved and transported on the outer surface of the support wheel by the transmission of the motor.
[0012] Preferably, a transmission block is fixedly installed on the lower surface of both sets of the third U-shaped frame. The two sets of transmission blocks are respectively threaded onto the positive and negative threads at both ends of the outer surface of the connecting rod, and the connecting rod is rotatably installed in the support frame.
[0013] Preferably, a handwheel is fixedly installed at one end of the connecting rod.
[0014] Preferably, the connecting rod can drive the positive and negative threads on the outer surface through a handwheel to drive two sets of transmission blocks, which in turn drive two sets of third U-shaped frames to slide synchronously inward or outward, thereby changing the distance between them to adapt to different sizes of wood flooring.
[0015] Preferably, the repair mechanism includes a linear module, which is fixedly installed on the upper surface of the overhead pole. An electric push rod is fixedly installed at one end of the moving block of the linear module. A splicing plate is fixedly installed on the outer surface of the piston rod of the electric push rod. A glue cylinder is fixedly installed inside the splicing plate. The glue discharge nozzle of the glue cylinder extends through to the lower surface of the splicing plate. A storage box is fixedly installed at one end of the linear module. A gear pump is fixedly installed on the upper surface of the storage box. The extraction port of the gear pump is connected to the storage box, and the discharge port of the gear pump is connected to the glue cylinder. This allows the glue cylinder to be moved laterally and vertically by the linear module and the electric push rod. The linear module, the gear pump, and the electric push rod are all controlled by a controller.
[0016] Preferably, a scraper is installed at the other end of the splicing board. One end of the scraper has an inclined V-shaped groove. The V-shaped groove of the scraper is opposite to the glue discharge nozzle of the glue tube, so that the scraper can surround the repair material discharged from the glue tube through the V-shaped groove and slide to fill the surface of the wood floor.
[0017] Preferably, a guide cylinder is fixedly installed at one end of the scraper, a guide block is slidably installed in the guide groove opened on the lower surface of the guide cylinder, a scraper plate is fixedly installed at one end of the guide block, multiple sets of scraper blades are fixedly installed on the lower surface of the scraper plate, a spring is provided in the guide groove of the guide cylinder, and the upper and lower ends of the spring are respectively fixedly connected between the upper surface of the guide groove and the upper surface of the guide block, so that the guide block can drive the scraper plate to contact the surface of the wooden floor by the spring force applied by the spring. A guide rail block is fixedly installed on the upper surface of the guide cylinder, and the guide rail block is slidably inserted into the moving block of the linear module.
[0018] This invention also provides a method for intelligent repair and shaping of surface defects in unfinished wood flooring, comprising the following steps:
[0019] S1. Before use, the handwheel can be rotated according to the size of the raw board to drive the positive and negative threads on the outer surface of the connecting rod to drive the two sets of transmission blocks to move inward or outward synchronously. Then, the transmission blocks can be used to drive the third U-shaped frame on the upper surface to slide laterally on the outer surface of the crossbar through the sliding sleeve on the lower surface, thereby adjusting the distance between the two sets of third U-shaped frames until it matches the size of the raw board.
[0020] S2. Subsequently, the motor can be started to drive the transmission column in the third frame, which in turn drives the transmission belt within the third frame. The substrate can then be transported to the support wheel in the first frame, and simultaneously, the substrate is gripped and transported by two sets of opposing transmission belts. Adjusting the spacing between the third frames ensures the substrate is transported in the same direction, preventing skewing. During the transport process, the substrate moves past the bottom of the laser scanner, allowing the scanner to emit a laser beam onto the substrate surface and receive the reflected laser signal. When the laser beam scans the substrate surface, it forms a point cloud on the surface. Clouds or lines, these data can be used to construct the three-dimensional outline of an object. In this system, the laser scanner calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes little, while when the surface of the board has pits, the angle of the reflected light changes much more, thus reflecting the height change of the surface (i.e., the pit). This enables the laser scanner to convert the scan data into digital signals and send them to the controller, so that the controller can sense the lateral position of the pits on the surface of the board.
[0021] S3. After the controller senses the lateral position of the pit on the surface of the sub-board, it can delay and sequentially control the linear module, electric push rod, and gear pump. The linear module will drive the glue cartridge at one end of the moving block to move laterally to the point with the pit, and activate the electric push rod to push the glue discharge nozzle of the glue cartridge vertically to the surface of the sub-board. At the same time, it will also push the scraper (and spatula) to slide and adhere to the surface of the sub-board. Then, the gear pump can be activated to draw the repair material in the storage tank into the glue cartridge and discharge it to the surface of the sub-board through the glue discharge nozzle. The repair fluid drawn by the gear pump increases or decreases according to the size of the pit, and the size of the pit is controlled by the signal sent by the laser scanner. The device identifies the surface of the board and then, as the board is continuously pushed, it can bring the repair material on the surface into the scraper. The scraper can then scrape the repair material into the pits of the board. As the board is continuously conveyed, the filled pits can move over the lower surface of the scraper again. The scraper slides in the guide cylinder through the guide block. The guide block, which slides in the guide cylinder, is subjected to a spring force by the spring inside the guide cylinder. This spring force causes the scraper to push against the surface of the board, thus scraping off the excess repair material. This achieves the purpose of automatic repair of the board.
[0022] S4. If the pits on the surface of the raw board are distributed in different positions, the straight module will drive the scraper to move laterally to the position of each pit in turn to fill the repair material into each pit in turn.
[0023] Compared with the prior art, the beneficial effects of the present invention are:
[0024] 1. Through the design of the support wheels, second U-shaped frame, laser scanner, transmission mechanism, and repair mechanism, the operator can adjust the spacing between the transmission mechanisms to match the size of the raw board. This allows the system to adapt to raw boards of different sizes, effectively processing both large and small boards, thus improving the system's versatility. Simultaneously, the tilt angle of the laser scanner can be adjusted by rotating the second U-shaped frame at one end of the connecting plate, ensuring the laser scanner faces the support wheels at the desired tilt angle, guaranteeing that the laser scanner faces the support wheels at the optimal angle. The raw plate is used to ensure the accuracy of laser scanning. Simultaneously, the wing bolts press against one end of the second U-shaped frame, allowing for angle adjustment of the second U-shaped frame and locking its position via the pressure of the wing bolts. The raw plate is then transported to the support wheels within the first U-shaped frame, where it is simultaneously engaged and transported by two sets of opposing transmission mechanisms. During this transport, the raw plate moves past the bottom of the laser scanner, allowing the scanner to emit a laser beam onto its surface and receive the reflected laser signal. As the laser beam scans the surface, it forms a point cloud on the object's surface. (Clouds) or lines, this data can be used to construct the three-dimensional contour of an object. In this system, the laser scanner calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. This method can quickly and accurately detect pits on the surface of the raw board, accurately sensing both the lateral position and height changes of the pits. Compared with manual inspection, this greatly improves inspection efficiency and accuracy, reducing the misjudgments and omissions that may occur with manual inspection. When the surface of the raw board is flat, the angle of reflected light changes little, while when the surface of the raw board has pits, the angle of reflected light changes much more, thus reflecting the height changes (i.e., depressions) of the surface. This allows the laser scanner to convert the scan data into digital signals and send them to the controller, thereby enabling the controller to... The device can sense the lateral position of the pits on the surface of the raw board. After the controller senses the lateral position of the pits on the surface of the raw board, it can control the repair mechanism to move laterally to the point with the pit and fill the surface of the raw board with repair material. Subsequently, as the raw board is continuously conveyed, the filled pits can be scraped flat, thus achieving the purpose of automatic repair of the raw board. If the pits on the surface of the raw board are distributed in different positions, the repair mechanism will move laterally to the position of each pit in turn to fill each pit with repair material in turn. This automated repair process not only reduces the error of manual operation, but also ensures that the repair material is accurately filled into the pits. Moreover, as the raw board is continuously conveyed, the filled pits can be scraped flat, realizing a fully automated process from detection to repair to scraping flat, improving repair efficiency and quality.
[0025] 2. Through the design of the motor, connecting rod, third U-shaped frame, transmission belt and sliding sleeve, before use, the handwheel can be rotated according to the size of the raw board to drive the positive and negative threads on the outer surface of the connecting rod to drive the two sets of transmission blocks to move synchronously inward or outward. Then, the transmission blocks can be used to drive the third U-shaped frame on the upper surface to slide laterally on the outer surface of the crossbar through the sliding sleeve on the lower surface, thereby adjusting the distance between the two sets of third U-shaped frames until it matches the size of the raw board. This adjustable design can adapt to raw boards of different sizes, improve the system's compatibility with raw boards of different specifications, and make the system's application range wider.
[0026] The motor can then be started to drive the transmission column in the third U-shaped frame, which in turn drives the transmission belt within the third U-shaped frame. The raw board can then be transported to the support wheel in the first U-shaped frame. Simultaneously, the raw board is bitten and transported by two sets of opposing transmission belts. Adjusting the spacing between the third U-shaped frames ensures that the raw board is transported in the same direction without skewing, thus ensuring the stability of the raw board during transport. This contributes to the accuracy of subsequent laser scanning and repair operations, because if the raw board is skewed during transport, it may lead to inaccurate laser scanning, affecting the detection of pits on the surface of the raw board and subsequent repair work.
[0027] As the conveyor belt transports the raw slab, it moves past the bottom of the laser scanner. This allows the laser scanner to emit a laser beam onto the surface of the slab and receive the laser signals reflected back from the surface. When the laser beam scans the slab surface, it forms a point cloud or lines on the object's surface. This data can be used to construct the object's three-dimensional contour. In this system, the laser scanner calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes little, while when the slab surface has pits, the angle of the reflected light changes significantly, reflecting the surface height changes (i.e., depressions). The laser scanner then converts the scan data into digital signals and sends them to the controller, allowing the controller to sense the lateral position of the pits on the slab surface. This automated data processing and transmission method reduces manual intervention, improves the speed and accuracy of data processing, and thus improves the overall efficiency of the raw slab repair system.
[0028] 3. Through the design of the storage tank, linear module, gear pump, glue cartridge, electric push rod, scraper, and spatula, the controller senses the lateral position of the pit on the surface of the substrate. It then delays and sequentially controls the linear module, electric push rod, and gear pump. The linear module moves the glue cartridge at one end of the moving block laterally to the pit location and activates the electric push rod to push the glue cartridge's discharge nozzle vertically onto the substrate surface. Simultaneously, it pushes the scraper (and spatula) to slide against the substrate surface. The gear pump then draws repair material from the storage tank into the glue cartridge and discharges it onto the substrate surface through the discharge nozzle. The amount of repair fluid drawn by the gear pump increases or decreases depending on the size of the pit, which is determined by a signal from a laser scanner. This precise control of the repair material filling amount avoids underfilling or overfilling. As the substrate is continuously pushed, the repair material... The scraper allows the repair material on the surface of the raw board to enter the scraper plate, which then scrapes the material into the pits of the raw board. As the raw board is continuously conveyed, the filled pits move over the underside of the scraper plate. The scraper plate slides in the guide cylinder via a guide block, which is spring-loaded by a spring within the cylinder. This spring-loaded spring force causes the scraper plate to press against the surface of the raw board, scraping away excess repair material. This helps maintain the flatness of the raw board surface, resulting in a cleaner and more aesthetically pleasing repaired surface, reducing the workload of subsequent cleaning. This achieves the purpose of automatic repair of the raw board. If the pits on the surface of the raw board are distributed in different positions, the linear module will sequentially move the scraper plate laterally to the position of each pit to fill each pit with repair material.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Please see Figures 1-8 This embodiment provides an intelligent control repair and shaping device for defects on the surface of a wooden board, including: a support frame 1, a first U-shaped frame 101 fixedly installed on the upper surface of the support frame 1, multiple sets of support wheels 102 rotatably installed inside the first U-shaped frame 101, a crossbar 107 fixedly installed on the upper surface of the support frame 1, and two sets of transmission mechanisms 2 slidably installed on the outer surface of the crossbar 107. The two sets of transmission mechanisms 2 can slide synchronously inward or outward on the outer surface of the crossbar 107 to change the distance between them to adapt to wooden boards of different sizes, so that the two sets of transmission mechanisms 2 can touch the two sides of the wooden board and move on the outer surface of the support wheels 102.
[0040] Two sets of connecting plates 103 are fixedly installed on the upper surface of the support frame 1. A second U-shaped frame 104 is rotatably installed between the two sets of connecting plates 103. The second U-shaped frame 104 rotates on the upper periphery of the transmission mechanism 2 through the connecting plates 103. A laser scanner 105 is fixedly installed on one end of the second U-shaped frame 104. The laser scanner 105 can tilt towards the support wheel 102 through the rotation of the second U-shaped frame 104, so that the laser scanner 105 can perform high-frequency scanning on the surface of the wood flooring through laser scanning, and convert the scanning data into digital signals and send them to the controller, so that the controller can fully perceive the surface flatness of the wood flooring.
[0041] Among them, a suspended rod 106 is fixedly installed on the other end of the upper surface of the support frame 1. The suspended rod 106 is suspended above the outer periphery of the transmission mechanism 2. A repair mechanism 3 is fixedly installed on the upper surface of the suspended rod 106. The repair mechanism 3 is controlled by a controller. After the controller receives the floor defect signal sent by the laser scanner 105, it will control the repair mechanism 3 to move laterally to the corresponding position and move vertically downward to spray repair material on the surface of the wood floor and scrape it into the corresponding pit. The laser scanner 105 and the controller are Leica RTC360 and Leica Cyclone Field 360, respectively.
[0042] One end of the connecting plate 103 is threaded with a wing bolt, which can press against one end of the second U-shaped frame 104, thereby locking the position of the second U-shaped frame 104 by pressing it against the end after the angle of the second U-shaped frame 104 is adjusted.
[0043] Through the design of the support wheel 102, the second U-shaped frame 104, the laser scanner 105, the transmission mechanism 2, and the repair mechanism 3, during use, the operator can adjust the spacing between the transmission mechanisms 2 to match the size of the raw board. This allows the system to adapt to raw boards of different sizes, effectively processing both large and small boards, thus improving the system's versatility. Simultaneously, the tilt angle of the laser scanner 105 can be adjusted by rotating the second U-shaped frame 104 at one end of the connecting plate 103, ensuring that the laser scanner 105 faces the support wheel 102 at the desired tilt angle, guaranteeing that the laser scanner 105 faces the support wheel 102 at the optimal angle. The blank plate on the support wheel 102 ensures the accuracy of laser scanning, and simultaneously causes the wing bolt thread to press against one end of the second U-shaped frame 104. This allows the angle of the second U-shaped frame 104 to be adjusted and its position locked by the pressure of the wing bolt. The blank plate can then be transported to the support wheel 102 inside the first U-shaped frame 101, and simultaneously, the blank plate is bitten and transported by two sets of opposing transmission mechanisms 2. During the transport process, the blank plate moves past the lower end of the laser scanner 105, allowing the laser scanner 105 to emit a laser beam onto the surface of the blank plate and receive the laser signal reflected back from the surface. When the laser beam scans the surface of the blank plate, it forms a point cloud on the surface. Clouds or lines, this data can be used to construct the three-dimensional contour of an object. In this system, the laser scanner 105 calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. This method can quickly and accurately detect pits on the surface of the raw board, accurately sensing both the lateral position and height changes of the pits. Compared with manual inspection, this greatly improves inspection efficiency and accuracy, and reduces the misjudgments and omissions that may occur with manual inspection. When the surface of the raw board is flat, the angle of reflected light changes little, while when the surface of the raw board has pits, the angle of reflected light changes much more, thus reflecting the height changes (i.e., depressions) of the surface, which in turn enables the laser scanner to... The scanner 105 converts the scanned data into digital signals and sends them to the controller, enabling the controller to sense the lateral position of the pits on the surface of the substrate. Once the controller detects the lateral position of the pits, it controls the repair mechanism 3 to move laterally to the location of the pit and fill the surface of the substrate with repair material. As the substrate is continuously conveyed, the filled pits are smoothed out, thus achieving automatic repair of the substrate. If the pits on the substrate surface are distributed in different locations, the repair mechanism 3 will sequentially move laterally to the location of each pit to fill each pit with repair material. This automated repair process not only reduces errors from manual operation but also ensures that the repair material is accurately filled into the pits.Furthermore, as the raw slab is continuously fed in, the filled pits can be smoothed out, achieving a fully automated process from detection to repair and smoothing, thus improving repair efficiency and quality.
[0044] like Figure 4 As shown, the transmission mechanism 2 includes two sets of third U-shaped frames 201. Sliding sleeves 202 are fixedly installed on the lower surface of the two sets of third U-shaped frames 201. The two sets of third U-shaped frames 201 are slidably installed on the outer surface of the crossbar 107 through the sliding sleeves 202, and the two sets of third U-shaped frames 201 are arranged opposite to each other. Two sets of transmission columns 203 are rotatably installed inside the third U-shaped frames 201. Transmission belts 204 are fitted on the outer surface of the two sets of transmission columns 203. A motor 205 is fixedly installed on the upper surface of the third U-shaped frames 201. The output shaft of the motor 205 passes through the third U-shaped frame 201 and is fixedly connected to one of the transmission columns 203. This allows the two sets of third U-shaped frames 201 to drive the transmission belts 204 to contact the two sides of the wooden floor and be driven by the motor 205 to move and transport on the outer surface of the support wheel 102.
[0045] Among them, the lower surfaces of the two sets of third U-shaped frames 201 are fixedly installed with transmission blocks 206. The two sets of transmission blocks 206 are respectively threaded onto the positive and negative threads at both ends of the outer surface of the connecting rod 207. The connecting rod 207 is rotatably installed in the support frame 1.
[0046] One end of the connecting rod 207 is fixedly equipped with a handwheel 208.
[0047] Among them, the connecting rod 207 can drive the positive and negative threads on the outer surface through the handwheel 208 to drive the two sets of transmission blocks 206 to drive the two sets of third U-shaped frames 201 to slide inward or outward in sync, thereby changing the distance between them to adapt to different sizes of wood flooring.
[0048] Through the design of motor 205, connecting rod 207, third U-shaped frame 201, transmission belt 204 and sliding sleeve 202, before use, the handwheel 208 can be rotated according to the size of the raw board to drive the positive and negative threads on the outer surface of the connecting rod 207 to drive the two sets of transmission blocks 206 to move synchronously inward or outward. Then, the transmission blocks 206 can be used to drive the third U-shaped frame 201 on the upper surface to slide laterally on the outer surface of the crossbar 107 through the sliding sleeve 202 on the lower surface, thereby adjusting the distance between the two sets of third U-shaped frames 201 until it matches the size of the raw board. This adjustable design can adapt to raw boards of different sizes, improve the system's compatibility with raw boards of different specifications, and make the system's application range wider.
[0049] Then, the motor 205 can be started to drive the transmission column 203 in the third U-shaped frame 201 to drive the transmission belt 204 to move within the third U-shaped frame 201. The raw board can then be transported to the support wheel 102 in the first U-shaped frame 101. At the same time, the raw board is bitten by the two sets of relatively driven transmission belts 204 and transported. Adjusting the spacing between the third U-shaped frames 201 can keep the raw board in the same direction during transport without skewing, ensuring the stability of the raw board during transport. This helps to improve the accuracy of subsequent laser scanning, repair and other operations. If the raw board is skewed during transport, it may lead to inaccurate laser scanning, affecting the detection of pits on the surface of the raw board and subsequent repair work.
[0050] During the conveyor belt 204's transport of the sub-board, the sub-board moves past the lower end of the laser scanner 105. This allows the laser scanner 105 to emit a laser beam onto the surface of the sub-board and receive the laser signal reflected back from the surface. When the laser beam scans the sub-board surface, it forms a point cloud or lines on the object's surface. This data can be used to construct the object's three-dimensional contour. In this system, the laser scanner 105 calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes little, while when the sub-board surface has pits, the angle of the reflected light changes significantly, reflecting the surface height changes (i.e., depressions). This allows the laser scanner 105 to convert the scan data into digital signals and send them to the controller, enabling the controller to sense the lateral position of the pits on the sub-board surface. This automated data processing and transmission method reduces manual intervention, improves the speed and accuracy of data processing, and thus improves the overall efficiency of the sub-board repair system.
[0051] like Figures 5-8 As shown, the repair mechanism 3 includes a linear module 302, which is fixedly installed on the upper surface of the overhead rod 106. An electric push rod 305 is fixedly installed at one end of the moving block of the linear module 302. A splicing plate 306 is fixedly installed on the outer surface of the piston rod of the electric push rod 305. A glue cylinder 304 is fixedly installed inside the splicing plate 306. The glue discharge nozzle of the glue cylinder 304 extends to the lower surface of the splicing plate 306. A storage box 301 is fixedly installed at one end of the linear module 302. A gear pump 303 is fixedly installed on the upper surface of the storage box 301. The extraction port of the gear pump 303 is connected to the storage box 301, and the discharge port of the gear pump 303 is connected to the glue cylinder 304. This allows the glue cylinder 304 to be driven to move laterally and vertically by the linear module 302 and the electric push rod 305. The linear module 302, the gear pump 303, and the electric push rod 305 are all controlled by a controller.
[0052] The other end of the splicing board 306 is equipped with a scraper 307. One end of the scraper 307 has an inclined V-shaped scraper groove. The V-shaped scraper groove of the scraper 307 is opposite to the glue discharge nozzle of the glue cylinder 304, so that the scraper 307 can surround the repair material discharged from the glue cylinder 304 through the V-shaped scraper groove and slide to fill the surface of the wood floor.
[0053] A guide cylinder 308 is fixedly installed at one end of the scraper 307. A guide block 311 is slidably installed in the guide groove opened on the lower surface of the guide cylinder 308. A scraper 309 is fixedly installed at one end of the guide block 311. Multiple scraper blades are fixedly installed on the lower surface of the scraper 309. A spring 312 is provided in the guide groove of the guide cylinder 308. The upper and lower ends of the spring 312 are respectively fixedly connected between the upper surface of the guide groove and the upper surface of the guide block 311, so that the guide block 311 can drive the scraper 309 to touch the surface of the wooden floor by the spring force applied by the spring 312. A guide rail block 310 is fixedly installed on the upper surface of the guide cylinder 308. The guide rail block 310 is slidably inserted into the moving block of the linear module 302.
[0054] Through the design of the storage box 301, linear module 302, gear pump 303, glue cartridge 304, electric push rod 305, scraper 307, and scraper 309, after the controller senses the lateral position of the pit on the surface of the raw board, it can delay and sequentially control the linear module 302, electric push rod 305, and gear pump 303. The linear module 302 will drive the glue cartridge 304 at one end of the moving block to move laterally to the point with the pit, and activate the electric push rod 305 to push the glue discharge nozzle of the glue cartridge 304 vertically to the surface of the raw board. Simultaneously, the scraper (307) and spatula (309) are pushed and slid against the surface of the substrate. Then, the gear pump (303) is activated to draw repair material from the storage tank (301) into the glue cartridge (304) and discharge it onto the surface of the substrate through the discharge nozzle. The amount of repair fluid drawn by the gear pump (303) increases or decreases depending on the size of the dent. The size of the dent is determined by a signal sent by the laser scanner (105) to the controller. This precise control of the repair material filling amount avoids insufficient or excessive filling. Subsequently, as the substrate... The continuous pushing action allows the raw board to carry the surface repair material into the scraper 307, which then scrapes the repair material into the recesses of the raw board. As the raw board is continuously conveyed, the filled recesses move again over the lower surface of the scraper 309. The scraper 309 slides within the guide cylinder 308 via the guide block 311. The guide block 311, sliding within the guide cylinder 308, is subjected to a spring-like force by the spring 312 within the guide cylinder 308, thus allowing the guide block 311 to... The spring 312 applies a spring-like thrust, which drives the scraper 309 to press against the surface of the sub-board, thereby scraping off excess repair material from the surface of the sub-board. This helps to maintain the flatness of the sub-board surface, making the repaired sub-board surface cleaner and more beautiful, and reducing the workload of subsequent cleaning work. This achieves the purpose of automatic repair of the sub-board. If the pits on the surface of the sub-board are distributed in different positions, the linear module 302 will drive the scraper 307 to move laterally to the position of each pit in turn to fill each pit with repair material in turn.
[0055] The intelligent control repair and shaping method for surface defects of raw wood flooring provided in this embodiment includes the following steps:
[0056] S1. Before use, the handwheel 208 can be rotated according to the size of the raw board to drive the positive and negative threads on the outer surface of the connecting rod 207 to drive the two sets of transmission blocks 206 to move inward or outward in sync. Then, the transmission blocks 206 can be used to drive the third U-shaped frame 201 on the upper surface to slide laterally on the outer surface of the crossbar 107 through the sliding sleeve 202 on the lower surface, thereby adjusting the distance between the two sets of third U-shaped frames 201 until it is adjusted to match the size of the raw board.
[0057] S2. Subsequently, the motor 205 can be started to drive the transmission column 203 in the third frame 201 to drive the transmission belt 204 to move within the third frame 201. The substrate can then be transported to the support wheel 102 in the first frame 101, and simultaneously, the substrate is gripped and transported by the two sets of opposing transmission belts 204. Adjusting the spacing between the third frames 201 ensures that the substrate is transported in the same direction without skewing. During the transport process, the substrate moves past the lower end of the laser scanner 105, allowing the laser scanner 105 to emit a laser beam onto the surface of the substrate and receive the laser signal reflected back from the substrate surface. When the laser beam scans the substrate surface, it forms a point cloud on the surface. Clouds or lines, these data can be used to construct the three-dimensional outline of an object. In this system, the laser scanner 105 calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes little, while when the surface of the board has pits, the angle of the reflected light changes much more, thus reflecting the height change of the surface (i.e., the pit). This enables the laser scanner 105 to convert the scan data into digital signals and send them to the controller, so that the controller can sense the lateral position of the pits on the surface of the board.
[0058] S3. After the controller senses the lateral position of the pit on the surface of the substrate, it can delay and sequentially control the linear module 302, the electric push rod 305, and the gear pump 303. The linear module 302 will drive the glue cylinder 304 at one end of the moving block to move laterally to the point with the pit, and start the electric push rod 305 to push the glue discharge nozzle of the glue cylinder 304 to move vertically to the surface of the substrate. At the same time, it will also push the scraper 307 and the scraper 309 to slide and adhere to the surface of the substrate. Then, the gear pump 303 can be started to draw the repair material in the storage box 301 into the glue cylinder 304 and discharge it to the surface of the substrate through the glue discharge nozzle. The repair fluid drawn by the gear pump 303 increases or decreases with the size of the pit. The size of the pit is controlled by the signal sent by the laser scanner 105. The device identifies the material, and as the substrate is continuously pushed, the substrate, along with the surface repair material, enters the scraper 307. The scraper 307 scrapes the repair material into the pits of the substrate. As the substrate is continuously conveyed, the filled pits move over the lower surface of the scraper 309 again. The scraper 309 slides in the guide cylinder 308 via the guide block 311. The guide block 311, which slides in the guide cylinder 308, is subjected to a spring force by the spring 312 inside the guide cylinder 308. This spring force causes the guide block 311 to push the scraper 309 against the surface of the substrate, scraping away excess repair material and thus achieving automatic repair of the substrate.
[0059] S4. If the pits on the surface of the raw board are distributed in different positions, the straight module 302 will drive the scraper 307 to move laterally to the position of each pit in turn to fill the repair material into each pit in turn.
[0060] Based on the above technical solution, the working steps of this solution are summarized as follows: Before use, the handwheel 208 can be rotated according to the size of the raw board to drive the positive and negative threads on the outer surface of the connecting rod 207 to drive the two sets of transmission blocks 206 to move synchronously inward or outward. This allows the transmission blocks 206 to drive the third U-shaped frame 201 on the upper surface to slide laterally on the outer surface of the crossbar 107 through the sliding sleeve 202 on the lower surface, thereby adjusting the distance between the two sets of third U-shaped frames 201 until it matches the size of the raw board. Then, the motor 205 can be started to drive the transmission column 203 inside the third U-shaped frame 201 to drive the transmission belt 204 across the third U-shaped frame 207. The transmission within the first frame 101 is used to transport the substrate to the support wheel 102 within the first frame 101. Simultaneously, the substrate is engaged and transported by two sets of opposing transmission belts 204. Adjusting the spacing between the third frame 201 ensures the substrate is transported in the same direction, preventing skewing. During transport, the transmission belts 204 move the substrate past the lower end of the laser scanner 105, allowing the scanner to emit a laser beam onto the substrate surface and receive the reflected laser signal. When the laser beam scans the substrate surface, it forms a point cloud on the surface. (Clouds) or lines, this data can be used to construct the three-dimensional contour of an object. In this system, the laser scanner 105 calculates the precise position of each point on the surface by measuring the time it takes for the laser beam to reflect back (i.e., time of flight) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes little, while when the surface of the substrate has pits, the angle of the reflected light changes much more, thus reflecting the height change of the surface (i.e., the depression). This allows the laser scanner 105 to convert the scan data into a digital signal and send it to the controller, enabling the controller to sense the lateral position of the pits on the substrate surface. After sensing the lateral position of the pits on the substrate surface, the controller can delay and sequentially control the linear module 302, the electric push rod 305, and the gear pump 303. The linear module 302 will drive the rubber cylinder 304 at one end of the moving block to move laterally. The electric push rod 305 moves to the point with the dent and pushes the glue discharge nozzle of the glue cartridge 304 vertically onto the surface of the substrate. At the same time, it also pushes the scraper plate 307 and the scraper plate 309 to slide against the surface of the substrate. Then, the gear pump 303 can be activated to draw the repair material in the storage box 301 into the glue cartridge 304 and discharge it onto the surface of the substrate through the glue discharge nozzle. The amount of repair fluid drawn by the gear pump 303 increases or decreases depending on the size of the dent. The size of the dent is identified by the signal sent by the laser scanner 105 to the controller. As the substrate is continuously pushed, the substrate can carry the repair material on its surface into the scraper plate 307, which can scrape the repair material into the dent of the substrate. As the substrate is continuously conveyed, the filled dent can move again over the lower surface of the scraper plate 309.The scraper plate 309 slides within the guide cylinder 308 via the guide block 311. The guide block 311, sliding within the guide cylinder 308, is subjected to a spring-like force by the spring 312. This spring-like force causes the scraper plate 309 to press against the surface of the subsurface board, scraping away excess repair material. This achieves automatic repair of the subsurface board. If the pits on the surface of the subsurface board are distributed in different locations, the linear module 302 will sequentially move the scraper plate 307 laterally to the position of each pit to fill each pit with repair material.
[0061] In summary, this system enables automatic detection of the flatness of the raw board surface during the conveying process, and can automatically fill the areas requiring repair with repair material. After filling with repair material, it can also repair and smooth out any pits or cracks filled with repair material, which helps maintain the flatness of the raw board surface, making the repaired raw board surface cleaner and more beautiful, and reducing the workload of subsequent cleaning work.

7. A wood floor board surface defect intelligent control repair shaping method, characterized in that: The intelligent control repair and shaping equipment for surface defects of unfinished wood flooring as described in any one of claims 1-6 is used to repair and shape the surface of unfinished wood flooring, comprising the following steps: S1. Before use, rotate the handwheel (208) according to the size of the raw board to drive the positive and negative threads on the outer surface of the connecting rod (207) to drive the two sets of transmission blocks (206) to move inward or outward in sync. Then, the transmission blocks (206) can drive the third U-shaped frame (201) on the upper surface to slide laterally on the outer surface of the crossbar (107) through the sliding sleeve (202) on the lower surface, thereby adjusting the distance between the two sets of third U-shaped frames (201) until it matches the size of the raw board. S2. Then, the motor (205) is started to drive the transmission column (203) in the third frame (201) to drive the transmission belt (204) to move within the third frame (201). The raw board is then transported to the support wheel (102) in the first frame (101). At the same time, the raw board is bitten and transported by the two sets of opposing transmission belts (204). The spacing between the third frames (201) is adjusted to keep the raw board in the same direction during transport and prevent it from tilting. During the transport process, the transmission belt (204) moves the raw board past the lower end of the laser scanner (105), allowing the laser scanner (105) to pass through the laser. The laser beam emits a laser onto the surface of the substrate and receives the laser signal reflected back from the substrate surface. When the laser beam scans the substrate surface, it forms a point cloud or lines on the surface of the object. These data are used to construct the three-dimensional contour of the object. The laser scanner (105) calculates the precise position of each point on the surface by measuring the time of reflection of the laser beam or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes little, while when there are pits on the substrate surface, the angle of the reflected light changes much, thus reflecting the height change of the surface. This enables the laser scanner (105) to convert the scanning data into digital signals and send them to the controller, so that the controller can sense the lateral position of the pits on the substrate surface. S3. After the controller senses the lateral position of the pit on the surface of the substrate, it delays and then controls the linear module (302), the electric push rod (305), and the gear pump (303) in sequence. The linear module (302) moves the glue cylinder (304) at one end of the moving block laterally to the point with the pit and starts the electric push rod (305) to push the glue discharge nozzle of the glue cylinder (304) vertically to the surface of the substrate. At the same time, it also pushes the scraper (307) and the spatula (309) to slide and adhere to the surface of the substrate. Then, the gear pump (303) is started to draw the repair material in the storage box (301) into the glue cylinder (304) and discharge it to the surface of the substrate through the glue discharge nozzle. The amount of repair material drawn by the gear pump (303) increases or decreases with the size of the pit. The size of the pit is controlled by the signal sent by the laser scanner (105). The device identifies the material, and as the substrate is continuously pushed, the substrate can carry the repair material on its surface into the scraper (307). The scraper (307) scrapes the repair material into the pits of the substrate. As the substrate is continuously conveyed, the filled pits can move over the lower surface of the scraper (309). The scraper (309) slides in the guide cylinder (308) through the guide block (311). The guide block (311) sliding in the guide cylinder (308) is subjected to a spring force by the spring (312) in the guide cylinder (308). The spring force applied by the spring (312) causes the guide block (311) to drive the scraper (309) to press against the surface of the substrate, thereby scraping off the excess repair material from the surface of the substrate, thus achieving the purpose of automatic repair of the substrate. S4. If the pits on the surface of the raw board are distributed in different positions, the straight module (302) will drive the scraper (307) to move laterally to the position of each pit in turn to fill the repair material into each pit in turn.
