[0015] The present invention also provides a method for intelligently controlling the repair and shaping of surface defects of a wood flooring plain board, comprising the following steps: S1. Before use, the hand wheel can be rotated according to the size of the plain 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, and then the transmission blocks can be used to drive the third C-shaped frame on the upper surface to slide horizontally on the outer surface of the cross bar through the sliding sleeve on the lower surface, so as to adjust the spacing between the two sets of third C-shaped frames until it is adjusted to match the size of the plain board; S2. Then the motor can be started to drive the transmission column in the third C-shaped frame to drive the transmission belt to transmit in the third C-shaped frame, and then the blank plate can be transported to the support wheel in the first C-shaped frame, and at the same time, the blank plate is bitten and transported by the two sets of relatively driven transmission belts, and the spacing between the third C-shaped frames is adjusted so that the blank plate can be transported in the same direction without deflection. In the process of the transmission belt driving the blank plate to transport, the blank plate will move from the lower end of the laser scanner, so that the laser scanner can emit a laser beam to the surface of the blank plate and receive the laser signal reflected from the surface of the blank plate. When the laser beam scans the surface of the blank plate, it will form a point cloud (Point Cloud) or lines, these data can be used to construct the three-dimensional contour of the 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., flight time) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes less, while when there are pits on the surface of the plain board, the angle of the reflected light changes more, thus reflecting the height change of the surface (i.e., depression), which 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 plain board; S3. After the controller senses the lateral position of the pit on the surface of the base plate, it can delay and control the linear module, electric push rod and gear pump in sequence. The linear module will drive the rubber cylinder at one end of the moving block to move horizontally to the point with the pit and start the electric push rod to push the rubber cylinder's discharge nozzle to move vertically to the surface of the base plate, and at the same time, it will also push the scraper plate (and shovel plate to slide and fit on the surface of the base plate. Then, the gear pump can be started to draw the repair material in the storage box into the rubber cylinder and discharge it to the surface of the base plate through the discharge nozzle. The repair liquid drawn by the gear pump increases or decreases with the size of the pit, and the size of the pit is controlled by the signal sent by the laser scanner. The device identifies, and then as the plain plate is continuously pushed, the plain plate can drive the repair material on the surface into the scraper plate, and the scraper plate can scrape the repair material into the pits of the plain plate. Then, as the plain plate is continuously transported, the filled pits can move again from the lower surface of the scraper plate, and the scraper plate slides in the guide cylinder through the guide block, and the guide block sliding in the guide cylinder is applied with a spring thrust by the spring in the guide cylinder, and then the guide block can drive the scraper plate to touch the surface of the plain plate through the spring thrust applied by the spring, so as to scrape off the excess repair material from the surface of the plain plate, that is, to achieve the purpose of automatic repair of the plain plate; S4. If the distribution positions of the pits on the surface of the plain board are different, the linear module will drive the scraper plate to move horizontally to the position of each pit in turn to fill the repair material into each pit in turn.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the design of the support wheel, the second C-shaped frame, the laser scanner, the transmission mechanism and the repair mechanism, when in use, the staff can adjust the spacing between the transmission mechanisms to match the size of the blank plate according to the size of the blank plate, which allows the system to adapt to blank plates of different sizes. Whether large or small, the blank plates can be effectively processed in the system, which improves the versatility of the system. At the same time, the tilt angle of the laser scanner can be adjusted. The tilt angle of the laser scanner can be adjusted by rotating the second C-shaped frame at one end of the connecting plate, so that the laser scanner can face the support wheel in the required tilt, which can ensure that the laser scanner can face the support wheel at the best angle. The blank plate is then conveyed to the support wheel in the first C-shaped frame, and the blank plate is bitten and conveyed by two sets of transmission mechanisms that are relatively driven. During the process of conveying the blank plate driven by the transmission mechanism, the blank plate will move past the lower end of the laser scanner, so that the laser scanner can emit a laser beam to the surface of the blank plate and receive the laser signal reflected from the surface of the blank plate. When the laser beam scans the surface of the blank plate, it will form a point cloud (Point Cloud) or lines, these data can be used to construct the three-dimensional contour of the 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., flight time) or the reflection angle of the beam. This method can quickly and accurately detect pits on the surface of the plain board, and can accurately perceive both the lateral position and height changes of the pits. Compared with manual detection, it greatly improves the detection efficiency and accuracy, and reduces the possible misjudgment and omissions of manual detection. When the surface of the plain board is flat, the angle of the reflected light changes less, while when there are pits on the surface of the plain board, the angle of the reflected light changes more, thereby reflecting the height change (i.e., depression) of the surface, which enables the laser scanner to convert the scanned data into digital signals and send them to the controller, so that the control The device can sense the lateral position of the pits on the surface of the plain board. After the controller senses the lateral position of the pits on the surface of the plain board, it can control the repair mechanism to move horizontally to the point with the pit and fill the repair material on the surface of the plain board. Subsequently, as the plain board is continuously conveyed, the filled pits can be scraped flat, thereby achieving the purpose of automatic repair of the plain board. If the distribution positions of the pits on the surface of the plain board are different, the repair mechanism will be moved horizontally to the position of each pit in turn to fill the repair material into each pit 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 plain board is continuously conveyed, the filled pits can be scraped flat, realizing a fully automated process from detection to repair and then to scraping flat, thereby improving the repair efficiency and quality.

[0017] 2. Through the design of the motor, the connecting rod, the third C-shaped frame, the transmission belt and the sliding sleeve, before use, the hand wheel can be rotated according to the size of the plain board to drive the positive thread and the negative thread on the outer surface of the connecting rod to drive the two sets of transmission blocks to move synchronously inward or outward, and then the transmission block can be used to drive the third C-shaped frame on the upper surface to slide horizontally on the outer surface of the cross bar through the sliding sleeve on the lower surface, so as to adjust the spacing between the two sets of third C-shaped frames until it is adjusted to match the size of the plain board. This adjustable design can adapt to plain boards of different sizes, improve the compatibility of the system with plain boards of different specifications, and make the system more widely used; Then the motor can be started to drive the transmission column in the third C-shaped frame to drive the transmission belt to transmit in the third C-shaped frame, and then the blank plate can be transported to the supporting wheel in the first C-shaped frame, and at the same time, the blank plate is bitten and transported by the two sets of relatively driven transmission belts, and the spacing between the third C-shaped frames can be adjusted to keep the blank plate in the same direction when being transported, without deflection, ensuring the stability of the blank plate during the transportation process, which is helpful for the accuracy of subsequent laser scanning, repair and other operations, because if the blank plate is deflected during transportation, it may cause inaccurate laser scanning, affecting the detection of pits on the surface of the blank plate and the subsequent repair work; When the transmission belt drives the blank plate to be transported, the blank plate will move past the lower end of the laser scanner, so that the laser scanner can emit laser to the surface of the blank plate through the laser beam and receive the laser signal reflected from the surface of the blank plate. When the laser beam scans the surface of the blank plate, it will form a point cloud (Point Cloud) or line on the surface of the object. These data can be used to construct the three-dimensional contour of the 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 be reflected back (i.e., flight time) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes less, and when there are pits on the surface of the blank plate, the angle of the reflected light changes more, thereby reflecting the height change of the surface (i.e., depression), which enables the laser scanner to convert the scanned data into a digital signal and send it to the controller, so that the controller can sense the lateral position of the pit on the surface of the blank plate. This automated data processing and transmission method reduces manual intervention, improves the speed and accuracy of data processing, and thus improves the work efficiency of the entire blank plate repair system.

[0018] 3. Through the design of the storage box, linear module, gear pump, rubber cylinder, electric push rod, scraper plate and shovel plate, after the controller senses the lateral position of the pit on the surface of the plain board, the controller can delay and control the linear module, electric push rod and gear pump in sequence, and the linear module will drive the rubber cylinder at one end of the moving block to move horizontally to the point with the pit and start the electric push rod to push the rubber cylinder's discharge nozzle to move vertically to the surface of the plain board, and at the same time, it will also push the scraper plate (and the shovel plate to slide and fit on the surface of the plain board, and then the gear pump can be started to draw the repair material in the storage box into the rubber cylinder and discharge it to the surface of the plain board through the discharge nozzle, and the repair liquid extracted by the gear pump increases or decreases with the size of the pit, and the size of the pit is identified by the signal sent by the laser scanner for the controller to identify. This method of accurately controlling the filling amount of the repair material can avoid insufficient or excessive filling of the repair material. Then, as the plain board is continuously pushed, the repair is carried out. The blank plate can drive the repair material on the surface into the scraper plate, and the scraper plate can scrape the repair material into the pits of the blank plate. Then, as the blank plate is continuously transported, the filled pits can move over the lower surface of the shovel plate again, and the shovel plate slides in the guide cylinder through the guide block, and the guide block sliding in the guide cylinder will be applied an elastic thrust by the spring in the guide cylinder, so that the guide block can drive the shovel plate to touch the surface of the blank plate through the elastic thrust applied by the spring to scrape off the excess repair material from the surface of the blank plate, which helps to maintain the flatness of the blank plate surface, makes the repaired blank plate surface more tidy and beautiful, and reduces the workload of subsequent cleaning work, that is, to achieve the purpose of automatic repair of the blank plate. If the distribution positions of the pits on the surface of the blank plate are different, the linear module will drive the scraper plate to move horizontally to the position of each pit in turn to fill the repair material into each pit in turn.

[0022] See also Figure 1-Figure 8 The present embodiment provides a surface defect intelligent control repair and shaping device for a wood floor plain board, comprising: a support frame 1, a first C-shaped frame 101 is fixedly installed on the upper surface of the support frame 1, a plurality of support wheels 102 are rotatably installed in the first C-shaped frame 101, a cross bar 107 is fixedly installed on the upper surface of the support frame 1, two sets of transmission mechanisms 2 are slidably installed on the outer surface of the cross bar 107, the two sets of transmission mechanisms 2 can synchronously slide inward or outward on the outer surface of the cross bar 107 to change the spacing between them to adapt to wood floors of different sizes, so that the two sets of transmission mechanisms 2 can touch both sides of the wood floor and drive to move on the outer surface of the support wheel 102; Among them, two groups of connecting plates 103 are fixedly installed on the upper surface of the support frame 1, and a second C-shaped frame 104 is rotatably installed between the two groups of connecting plates 103. The second C-shaped frame 104 is rotated on the outer upper end of the transmission mechanism 2 through the connecting plates 103. A laser scanner 105 is fixedly installed on one end of the second C-shaped frame 104. The laser scanner 105 can face the supporting wheel 102 in an inclined shape through the rotation of the second C-shaped frame 104, so that the laser scanner 105 can perform high-frequency scanning on the surface of the wooden floor 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 wooden floor; Among them, an overhead rod 106 is fixedly installed on the other end of the upper surface of the support frame 1. The overhead rod 106 is suspended on the outer upper end of the transmission mechanism 2. A repair mechanism 3 is fixedly installed on the upper surface of the overhead 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, the controller will control the repair mechanism 3 to move horizontally to the corresponding position and move vertically downward to spray the repair material on the surface of the wooden floor and scrape it into the corresponding pits. The models of the laser scanner 105 and the controller are Leica RTC360 and Leica Cyclone Field 360 respectively.

[0023] Among them, a butterfly bolt is threadedly installed at one end of the connecting plate 103, so that the butterfly bolt can be threadedly pressed against one end of the second C-shaped frame 104, so that the angle of the second C-shaped frame 104 can be adjusted and its position can be locked by pressing the butterfly bolt.

[0024] Through the design of the support wheel 102, the second C-shaped frame 104, the laser scanner 105, the transmission mechanism 2 and the repair mechanism 3, when in use, the staff can adjust the spacing between the transmission mechanisms 2 to match the size of the blank plate according to the size of the blank plate, which allows the system to adapt to blank plates of different sizes. Whether large or small, the blank plates can be effectively processed in the system, which improves the versatility of the system, and at the same time, the inclination angle of the laser scanner 105 can be regulated. The inclination angle of the laser scanner 105 can be adjusted by rotating the second C-shaped frame 104 at one end of the connecting plate 103, so that the laser scanner 105 can face the support wheel 102 in the required inclination, which can ensure that the laser scanner 105 can face the support wheel 102 at the best angle The blank plate on the support wheel 102 is ensured to ensure the accuracy of laser scanning, and at the same time, the butterfly bolt thread is pressed against one end of the second C-shaped frame 104, so that the angle of the second C-shaped frame 104 can be adjusted and its position can be locked by pressing the butterfly bolt, and then the blank plate can be transported to the support wheel 102 in the first C-shaped frame 101, and at the same time, the blank plate is bitten and transported by two sets of relatively transmitted transmission mechanisms 2. In the process of the transmission mechanism 2 driving the blank plate to be transported, the blank plate will move past the lower end of the laser scanner 105, so that the laser scanner 105 can emit a laser beam to the surface of the blank plate through a laser beam, and receive the laser signal reflected from the surface of the blank plate. When the laser beam scans the surface of the blank plate, it will form a point cloud (Point Cloud) or lines, these data can be used to construct the three-dimensional contour of the 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., flight time) or the reflection angle of the beam. This method can quickly and accurately detect the pits on the surface of the plain board, and can accurately perceive both the lateral position and height changes of the pits. Compared with manual detection, it greatly improves the detection efficiency and accuracy, and reduces the possible misjudgment and omissions of manual detection. When the surface of the plain board is flat, the angle of the reflected light changes less, while when there are pits on the surface of the plain board, the angle of the reflected light changes more, thereby reflecting the height change (i.e., depression) of the surface, which can enable the laser scanner to detect the pits on the surface of the plain board quickly and accurately. The scanner 105 converts the scanned data into digital signals and sends them to the controller, so that the controller can sense the lateral position of the pits on the surface of the plain board. After sensing the lateral position of the pits on the surface of the plain board, the controller can control the repair mechanism 3 to move horizontally to the point with the pit and fill the repair material on the surface of the plain board. Then, as the plain board is continuously transported, the filled pits can be scraped flat, that is, the purpose of automatic repair of the plain board is achieved. If the distribution positions of the pits on the surface of the plain board are different, the repair mechanism 3 will be moved horizontally to the position of each pit in turn to fill the repair material into each pit 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 pit.Moreover, as the raw board is continuously conveyed, the filled pits can be scraped flat, realizing a fully automated process from detection to repair and then to scraping flat, thus improving the repair efficiency and quality.

[0029] Through the design of the motor 205, the connecting rod 207, the third U-shaped frame 201, the transmission belt 204 and the sliding sleeve 202, before use, the hand wheel 208 can be rotated according to the size of the plain board to drive the positive thread and the negative thread on the outer surface of the connecting rod 207 to drive the two sets of transmission blocks 206 to move synchronously inward or outward, and then the transmission block 206 can be used to drive the third U-shaped frame 201 on the upper surface to slide horizontally on the outer surface of the cross bar 107 through the sliding sleeve 202 on the lower surface, so as to adjust the spacing between the two sets of third U-shaped frames 201 until it is adjusted to match the size of the plain board. This adjustable design can adapt to plain boards of different sizes, improve the compatibility of the system with plain boards of different specifications, and make the system more widely used. Then the motor 205 can be started to drive the transmission column 203 in the third C-shaped frame 201 to drive the transmission belt 204 to transmit in the third C-shaped frame 201, and then the blank plate can be transported to the support wheel 102 in the first C-shaped frame 101, and at the same time, the blank plate is bitten and transported by the two sets of relatively transmitted transmission belts 204, and the spacing between the third C-shaped frames 201 is adjusted so that the blank plate can be transported in the same direction without deflection, thereby ensuring the stability of the blank plate during the transportation process, and facilitating the accuracy of subsequent laser scanning, repairing and other operations, because if the blank plate is deflected during transportation, it may cause inaccurate laser scanning, affecting the detection of pits on the surface of the blank plate and the subsequent repair work; When the conveyor belt 204 drives the blank plate to be transported, the blank plate will move past the lower end of the laser scanner 105, so that the laser scanner 105 can emit laser light to the surface of the blank plate through the laser beam and receive the laser signal reflected from the surface of the blank plate. When the laser beam scans the surface of the blank plate, it will form a point cloud (Point Cloud) or lines on the surface of the object. These data can be used to construct the three-dimensional contour of the 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 be reflected back (i.e., the flight time) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes less, and when there are pits on the surface of the blank plate, the angle of the reflected light changes more, thereby reflecting the height change of the surface (i.e., the depression), so that the laser scanner 105 can convert the scanned data into a digital signal and send it to the controller, so that the controller can sense the lateral position of the pit on the surface of the blank plate. This automated data processing and transmission method reduces manual intervention, improves the speed and accuracy of data processing, and thus improves the working efficiency of the entire blank plate repair system.

[0031] A scraping plate 307 is installed at the other end of the splicing plate 306. An inclined V-shaped scraping groove is opened at one end of the scraping plate 307. The V-shaped scraping groove of the scraping plate 307 is opposite to the glue discharge nozzle of the glue cartridge 304, so that the scraping plate 307 can enclose the repair material discharged from the glue cartridge 304 through the V-shaped scraping groove and can slide and fill it on the surface of the wooden floor.

[0032] A guide cylinder 308 is fixedly installed at one end of the scraper plate 307, and a guide block 311 is slidably installed in a guide groove provided on the lower surface of the guide cylinder 308. A shovel plate 309 is fixedly installed at one end of the guide block 311, and a plurality of shovel blades are fixedly installed on the lower surface of the shovel plate 309. A spring 312 is provided in the guide groove of the guide cylinder 308, and the upper and lower ends of the spring 312 are respectively fixedly connected between the upper surface in the guide groove and the upper surface of the guide block 311, so that the guide block 311 can drive the shovel plate 309 to touch the surface of the wooden floor through the elastic thrust applied by the spring 312. A guide rail block 310 is fixedly installed on the upper surface of the guide cylinder 308, and the guide rail block 310 is slidably inserted in the moving block of the linear module 302.

[0033] Through the design of the storage box 301, the linear module 302, the gear pump 303, the glue cylinder 304, the electric push rod 305, the scraping plate 307 and the shovel plate 309, after the controller senses the lateral position of the pit on the surface of the plain board, the controller can delay and control the linear module 302, the electric push rod 305 and the gear pump 303 in sequence, and the linear module 302 will drive the glue cylinder 304 at one end of the moving block to move horizontally 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 plain board, and At the same time, the scraper plate (307 and the shovel plate 309 are pushed together to slide and fit on the surface of the plain board. 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 plain board through the glue discharge nozzle. The repair liquid drawn by the gear pump 303 increases or decreases with the size of the pit, and the size of the pit is identified by the signal sent by the laser scanner 105 for the controller to identify. This method of accurately controlling the filling amount of the repair material can avoid insufficient or excessive filling of the repair material. Then, as the plain board is The scraper 307 is continuously pushed, so that the base plate can drive the repair material on the surface into the scraper plate 307, and the scraper plate 307 can scrape the repair material into the pits of the base plate. Then, as the base plate is continuously transported, the filled pits can move over the lower surface of the scraper plate 309 again, and the scraper plate 309 slides in the guide cylinder 308 through the guide block 311, and the guide block 311 sliding in the guide cylinder 308 is applied with a spring thrust by the spring 312 in the guide cylinder 308, so that the guide block 311 can be pushed by the spring The elastic thrust exerted by the spring 312 drives the scraper plate 309 to touch the surface of the plain board through the elastic thrust to scrape off the excess repair material from the surface of the plain board, which helps to maintain the flatness of the surface of the plain board, making the repaired surface of the plain board more tidy and beautiful, reducing the workload of subsequent cleaning work, that is, achieving the purpose of automatic repair of the plain board. If the distribution positions of the pits on the surface of the plain board are different, the linear module 302 will drive the scraper plate 307 to move horizontally to the position of each pit in turn to fill the repair material into each pit in turn.

[0034] The method for intelligently controlling and repairing surface defects of a wood flooring provided in this embodiment comprises the following steps: S1. Before use, the hand wheel 208 can be rotated according to the size of the plain 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 synchronously, and then the transmission blocks 206 can be used to drive the third U-shaped frame 201 on the upper surface to slide horizontally on the outer surface of the cross bar 107 through the sliding sleeve 202 on the lower surface, so as to adjust the spacing between the two sets of third U-shaped frames 201 until it is adjusted to match the size of the plain board; S2. The motor 205 can then be started to drive the transmission column 203 in the third C-shaped frame 201 to drive the transmission belt 204 to transmit in the third C-shaped frame 201. The blank plate can then be transported to the support wheel 102 in the first C-shaped frame 101, and at the same time, the blank plate is bitten and transported by the two sets of relatively transmitted transmission belts 204. The spacing between the third C-shaped frames 201 is adjusted so that the blank plate can be transported in the same direction without deflection. In the process of the transmission belt 204 driving the blank plate to be transported, the blank plate will move past the lower end of the laser scanner 105, so that the laser scanner 105 can emit a laser beam to the surface of the blank plate through a laser beam and receive the laser signal reflected from the surface of the blank plate. When the laser beam scans the surface of the blank plate, it will form a point cloud (Point Cloud) or lines, these data can be used to construct the three-dimensional contour of the 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., flight time) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes slightly, while when there are pits on the surface of the plain board, the angle of the reflected light changes greatly, thereby reflecting the height change of the surface (i.e., depression), which enables the laser scanner 105 to convert the scanned data into a digital signal and send it to the controller, so that the controller can sense the lateral position of the pits on the surface of the plain board; S3. After the controller senses the lateral position of the pit on the surface of the base plate, it can delay and control the linear module 302, the electric push rod 305 and the gear pump 303 in sequence. The linear module 302 will drive the rubber cylinder 304 at one end of the moving block to move horizontally to the point with the pit and start the electric push rod 305 to push the glue discharge nozzle of the rubber cylinder 304 to move vertically to the surface of the base plate, and at the same time, it will also push the scraper plate 307 and the shovel plate 309 to slide and fit on the surface of the base plate. Then, the gear pump 303 can be started to draw the repair material in the storage box 301 into the rubber cylinder 304 and discharge it onto the surface of the base plate through the glue discharge nozzle. The repair liquid extracted by the gear pump 303 increases or decreases with the size of the pit, and the size of the pit is controlled by the signal sent by the laser scanner 105. The controller identifies that, as the plain plate is continuously pushed, the plain plate can drive the repair material on the surface into the scraper plate 307, and the scraper plate 307 can scrape the repair material into the pits of the plain plate. Then, as the plain plate is continuously transported, the filled pits can move again from the lower surface of the shovel plate 309, and the shovel plate 309 slides in the guide cylinder 308 through the guide block 311, and the guide block 311 sliding in the guide cylinder 308 is applied with a spring thrust by the spring 312 in the guide cylinder 308, so that the guide block 311 can drive the shovel plate 309 to touch the surface of the plain plate through the spring thrust applied by the spring 312, so as to scrape off the excess repair material from the surface of the plain plate, that is, to achieve the purpose of automatic repair of the plain plate; S4. If the distribution positions of the pits on the surface of the plain board are different, the linear module 302 will drive the scraping plate 307 to move horizontally to the position of each pit in turn to fill the repair material into each pit in turn.

[0035] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: before use, the hand wheel 208 can be rotated according to the size of the plain board to drive the positive thread and the negative thread on the outer surface of the connecting rod 207 to drive the two sets of transmission blocks 206 to move synchronously inward or outward, and then the transmission block 206 can be used to drive the third U-shaped frame 201 on the upper surface to slide horizontally on the outer surface of the cross bar 107 through the sliding sleeve 202 on the lower surface, so as to adjust the spacing between the two sets of third U-shaped frames 201 until it is adjusted to match the size of the plain board, and 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 on the third U-shaped frame 20 1, and then the blank board can be transported to the support wheel 102 in the first U-shaped frame 101, and at the same time, the blank board is bitten and transported by the two sets of transmission belts 204 that drive relatively, and the spacing between the third U-shaped frames 201 is adjusted so that the blank board can be transported in the same direction without deflection. In the process of the transmission belt 204 driving the blank board to be transported, the blank board will move from the lower end of the laser scanner 105, so that the laser scanner 105 can emit a laser beam to the surface of the blank board through the laser beam and receive the laser signal reflected from the surface of the blank board. When the laser beam scans the surface of the blank board, it will form a point cloud (Point Cloud) or lines, these data can be used to construct the three-dimensional contour of the 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., flight time) or the reflection angle of the beam. When the surface is flat, the angle of the reflected light changes slightly, while when there are pits on the surface of the plain board, the angle of the reflected light changes greatly, thereby reflecting the height change of the surface (i.e., depression), thereby enabling the laser scanner 105 to convert the scanned data into a digital signal and send it to the controller, so that the controller can sense the lateral position of the pit on the surface of the plain board. After the controller senses the lateral position of the pit on the surface of the plain board, it can delay and control the linear module 302, the electric push rod 305 and the gear pump 303 in sequence, and the linear module 302 will drive the rubber cylinder 304 at one end of the moving block to move horizontally. The glue discharge nozzle of the glue cylinder 304 is moved to the point with the pit and the electric push rod 305 is started to push the glue discharge nozzle of the glue cylinder 304 to move vertically to the surface of the plain board, and at the same time, the scraper plate 307 and the shovel plate 309 are pushed to slide and fit on the surface of the plain board. 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 plain board through the glue discharge nozzle, and the repair liquid extracted by the gear pump 303 increases or decreases with the size of the pit, and the size of the pit is identified by the signal sent by the laser scanner 105 for the controller to identify. Then, as the plain board is continuously pushed, the plain board can drive the repair material on the surface into the scraper plate 307, and the scraper plate 307 can scrape the repair material into the pit of the plain board. Then, as the plain board is continuously transported, the filled pit can be moved again from the lower surface of the shovel plate 309.The scraper plate 309 slides in the guide cylinder 308 through the guide block 311, and the guide block 311 sliding in the guide cylinder 308 is exerted with an elastic thrust by the spring 312 in the guide cylinder 308, so that the guide block 311 can drive the scraper plate 309 to touch the surface of the plain board through the elastic thrust exerted by the spring 312 to scrape off the excess repair material from the surface of the plain board, that is, to achieve the purpose of automatic repair of the plain board. If the distribution position of the pits on the surface of the plain board is different, the linear module 302 will drive the scraper plate 307 to move horizontally to the position of each pit in turn to fill the repair material into each pit in turn.

[0036] In summary: it can automatically detect the flatness of the surface of the plain board during the transportation process, and can automatically fill the repair material in the parts that need to be repaired. After filling the repair material, it can also trim and scrape the pits or cracks filled with the repair material, which helps to maintain the flatness of the surface of the plain board, make the repaired surface of the plain board more tidy and beautiful, and reduce the workload of subsequent cleaning work.
