[0001] The present invention relates to the technical field of furniture production, and specifically to a laser measuring device for furniture production. Background Art

[0002] Furniture production refers to the industrialized or manual process of converting raw materials such as wood, metal, plastic, fabric, etc. into functional or decorative furniture products through a series of processes such as design, processing, and assembly. Its core goal is to meet people's needs for space utilization, comfort, and aesthetics in scenarios such as life, work, and entertainment. During furniture production, laser measuring equipment is required to measure the dimensions of the boards.

[0003] Currently, during the processing of furniture boards, it is necessary to first use laser measuring equipment to measure the dimensions of the boards, then calculate the hole opening positions and cutting paths based on the dimensions, and then control the machine tool to perform processing operations. However, in actual use, the dust and debris generated during processing will adhere to the lens of the laser measuring equipment, making it inconvenient to clean, resulting in the problem that when too much dust and impurities adhere, it will affect the subsequent measurement accuracy.

A detection port is opened on the bottom surface of the bottom plate. One end of the top of the bottom plate is provided with a brush plate, and the other end of the top of the bottom plate is fixed with a first spring seat. A cover plate is arranged on the top of the first spring seat. The two sides of the cover plate are rotatably connected with rollers, and a limiting ring is arranged on the top of the rollers.

[0006] Furthermore, the limiting ring is fixedly connected with the top cover, the top cover is rotatably connected with the rotating shaft, and the top cover is slidably connected with the bottom plate.

[0007] Furthermore, dust removal components are connected to the upper and lower ends of the rotating shaft, and the dust removal components include a first filter plate. The first filter plate is arranged on one side of the top cover. A dust suction port is opened on one side of the connecting cover, and a second filter plate is slidably connected inside the connecting cover.

[0008] Further, a guiding groove is formed on the outer side of the upper part of the rotating shaft, and a sliding column is slidably connected inside the guiding groove. One end of the sliding column is fixed with a sliding sleeve, and a lifting plate is fixed in the middle of the outer peripheral surface of the sliding sleeve. A guiding strip is slidably connected to the outside of the lifting plate.

[0009] Further, the guiding groove is composed of two symmetric inclined grooves, and the two ends of the two inclined grooves are communicated with each other.

[0010] Further, one side of the guiding strip is connected with a fixed cylinder, and first one-way valves are connected to the upper and lower ends of the fixed cylinder. Second one-way valves are connected to the upper and lower ends of the rotating shaft.

[0011] Further, a dust collection assembly is arranged at the center of the bottom of the bottom plate. The dust collection assembly includes a dust collection box. The dust collection box is slidably connected to the center of the bottom of the bottom plate, and reset springs are arranged inside the four corners of the dust collection box. The top of the reset spring is connected with a support column, and the support column is fixedly connected with the second filter plate.

[0012] Further, top rods are arranged at both ends of the top of the second filter plate, and the top rods are slidably connected with the connecting cover. A limiting convex ring is slidably connected to the top of the top rod, and the limiting convex ring is fixedly connected with the top cover.

[0013] Further, a second spring seat is arranged on one side of the dust collection box, and one end of the second spring seat is connected with a connecting frame, and the connecting frame is U-shaped.

[0014] Further, the support column is slidably connected with the dust collection box, and the connecting frame is also slidably connected with the dust collection box.

[0015] The present invention provides a laser measuring device for furniture production, having the following beneficial effects:

[0016] 1. The present invention realizes the functions of lens protection and automatic cleaning through the rotatable bottom plate structure. During scanning measurement, the detection port is located below the lens to avoid occlusion and ensure normal operation. During the protection stage, the motor drives the gear set to drive the bottom plate to rotate, so that the brush plate reciprocates to clean the surface of the lens. Subsequently, the cover plate automatically moves below the lens to form a physical barrier, effectively isolating the dust pollution generated during processing. The integrated design of cleaning and protection not only extends the service life of the equipment, but its reversible rotation mechanism can also trigger the brush to clean twice again before the next measurement, providing double protection to ensure that the lens is always in a clean state, significantly improving the long-term measurement accuracy and working stability of the laser scanner.

[0017] 2. The present invention adopts a linkage pneumatic dust removal system. When the brush is cleaning, the rotating shaft synchronously drives the piston structure to generate negative pressure suction. Through the design of a two-way air flow channel, the sweeping and suction operations are synchronized. The double-chamber structure separated by the lifting plate cooperates with the one-way valve to form a continuous air flow, which can not only suck the dust swept by the brush into the filtering device, but also blow the lens with clean air flow to enhance the cleaning effect. The specially designed guiding mechanism ensures the precise vertical movement of the piston. The alternating working mode of the double chambers enables the device to maintain a stable dust suction capacity during both forward and reverse rotations. Through this dynamic dust removal structure, the cleaning efficiency is significantly improved.

[0018] 3. When the bottom plate rotates to drive the dust collection box to rotate synchronously in the present invention, the ejector rod will contact the fixed convex ring to generate regular vibrations, causing the dust on the surface of the filter plate to automatically fall off into the detachable dust collection box. At the same time, the spring positioning structure cooperates with the plug-in structure to realize the quick disassembly and assembly of the dust collection box. During maintenance, only need to press the connection frame to complete the separation of the locking mechanism. This self-cleaning collection system not only prevents the filter screen from being blocked and maintains the stability of the suction force, but its modular design also reduces the time-consuming of daily maintenance, which is beneficial to improving the convenience and safety of equipment operation and maintenance.

[0027] Please refer to Figures 1 to 4 The present invention provides a technical solution: a laser measurement device for furniture production, including a laser scanner 1 and a cleaning component 3. A top cover 2 is fixed on the outer side of the lower part of the laser scanner 1. The cleaning component 3 is arranged at the lower part of the laser scanner 1, and the cleaning component 3 includes a motor 301. The motor 301 is arranged on the top of the top cover 2, and the output shaft end of the motor 301 is connected with a driving gear 302. One end of the driving gear 302 meshes with a ring gear 303, and a rotating shaft 304 is fixed inside the ring gear 303. The inside of the rotating shaft 304 is hollow. The bottom of the rotating shaft 304 is provided with a connecting cover 305, and the bottom of the connecting cover 305 is fixedly connected with a bottom plate 306. A detection port 307 is opened on the bottom surface of the bottom plate 306. One end of the top of the bottom plate 306 is provided with a brush plate 308, and the other end of the top of the bottom plate 306 is fixed with a first spring seat 309. A cover plate 310 is arranged on the top of the first spring seat 309. The two sides of the cover plate 310 are rotatably connected with rollers 311, and a limit ring 312 is arranged on the top of the roller 311. The limit ring 312 is fixedly connected with the top cover 2. The top cover 2 is rotatably connected with the rotating shaft 304, and the top cover 2 is slidably connected with the bottom plate 306;

[0028] The specific operation is as follows. During the scanning measurement, since the detection port 307 will be located below the lens of the laser scanner 1 and will not block it, the scanning measurement operation can proceed normally. After measuring the sheet material, when the lens needs to be protected, the motor 301 can be started, which drives the bottom plate 306 to rotate clockwise through the driving gear 302, the gear ring 303, the rotating shaft 304, and the connecting cover 305, so that the brush plate 308 can be moved below the lens. At this time, when the bottom plate 306 is controlled to rotate reciprocally, the surface of the lens can be automatically cleaned. After cleaning, by continuing to rotate the bottom plate 306 clockwise, the cover plate 310 can be moved below the lens of the laser scanner 1. At this time, the roller 311 will synchronously move to the recessed part of the limit ring 312, and the first spring seat 309 will push the cover plate 310 to cover the bottom of the lens, so that during the processing of the sheet material, the lens of the laser scanner 1 will not be exposed to the outside and be contaminated. Subsequently, before use, by controlling the bottom plate 306 to rotate counterclockwise, the cover plate 310 can be separated from the lens first. Then, during the process of moving the detection port 307 below the laser scanner 1, the brush plate 308 will also clean the lens of the laser scanner 1 again, avoiding affecting the scanning measurement accuracy of the laser scanner 1 due to the attachment of impurities.

[0029] Please refer to Figures 5 to 6 The upper and lower ends of the rotating shaft 304 are connected with a dust removal component 4, and the dust removal component 4 includes a first filter plate 401. One side of the top cover 2 is provided with the first filter plate 401. A dust suction port 402 is opened on one side of the connecting cover 305, and a second filter plate 403 is slidably connected inside the connecting cover 305. A guiding groove 404 is opened on the outer side of the upper part of the rotating shaft 304, and a sliding column 405 is slidably connected inside the guiding groove 404. One end of the sliding column 405 is fixed with a sliding sleeve 406, and a lifting plate 407 is fixed in the middle of the outer peripheral surface of the sliding sleeve 406. A guiding bar 408 is slidably connected to the outside of the lifting plate 407. The guiding groove 404 is composed of two symmetrical inclined grooves, and the two ends of the two inclined grooves are interconnected. One side of the guiding bar 408 is connected with a fixed cylinder 409, and the upper and lower ends of the fixed cylinder 409 are connected with a first one-way valve 410. The upper and lower ends of the rotating shaft 304 are connected with a second one-way valve 411;

[0030] The specific operation is as follows. When the rotating shaft 304 rotates to make the brush plate 308 clean the lens, the rotating shaft 304 will also push the sliding column 405 through the guiding groove 404. At this time, since the guiding strip 408 will limit the rotation of the lifting plate 407 and make it move vertically only, the sliding column 405 will drive the sliding sleeve 406 to move up and down under the guidance of the inclined surface of the guiding groove 404. The lifting plate 407 will divide the interior of the fixed cylinder 409 into two upper and lower chambers. Therefore, when the height of the lifting plate 407 changes, the size of the chamber will also change synchronously. When the chamber space decreases, the air inside will be discharged through the first one-way valve 410. When the chamber space increases, it will suck the interior of the connecting cover 305 through the second one-way valve 411 and the rotating shaft 304. Therefore, the dust and impurities swept by the brush plate 308 can be sucked into the connecting cover 305 through the dust suction port 402, and the second filter plate 403 will intercept the dust and impurities. At the same time, the position of the first filter plate 401 is close to the lens of the laser scanner 1. Therefore, part of the clean external air flow can also blow to the lens surface, thereby improving the cleaning effect. And there are two chambers, so continuous suction can be carried out during the reciprocating rotation of the rotating shaft 304, which is beneficial to maintaining the overall dust removal effect.

[0031] Please refer to Figures 6 to 7 , a dust collection assembly 5 is provided at the center of the bottom of the bottom plate 306. The dust collection assembly 5 includes a dust collection box 501. The dust collection box 501 is slidably connected to the center of the bottom of the bottom plate 306. The four corners of the dust collection box 501 are internally provided with return springs 502. The top of the return spring 502 is connected to a support column 503, and the support column 503 is fixedly connected to the second filter plate 403. The top ends of the second filter plate 403 are provided with ejector rods 504, and the ejector rods 504 are slidably connected to the connecting cover 305. The top of the ejector rod 504 is slidably connected to a limiting convex ring 505, and the limiting convex ring 505 is fixedly connected to the top cover 2. One side of the dust collection box 501 is provided with a second spring seat 506, and one end of the second spring seat 506 is connected to a connecting frame 507, and the connecting frame 507 is U-shaped. The end of the connecting frame 507 is fixed with a positioning block 508, and the outside of the positioning block 508 is slidably connected to a connecting ear 509. The connecting ear 509 is L-shaped, and the connecting ear 509 is fixedly connected to the bottom plate 306. The support column 503 is slidably connected to the dust collection box 501, and the connecting frame 507 is also slidably connected to the dust collection box 501;

[0032] The specific operation is as follows. During the rotation of the bottom plate 306, the dust collection box 501 will also be driven to rotate synchronously. Since the reset spring 502 will push the support column 503, the ejector rod 504 will be in close contact with the limit convex ring 505, and the limit convex ring 505 is fixedly installed on the top cover 2. Therefore, the ejector rod 504 will slide at the bottom of the limit convex ring 505, enabling the second filter plate 403 to vibrate up and down. Thus, during continuous dust collection, part of the dust and impurities will be shaken off and fall into the lower dust collection box 501 for collection, avoiding the situation where dust and impurities continuously adhere to the second filter plate 403 and cause blockage. And when it is necessary to disassemble and pour the dust collection box 501, just push the connecting frame 507, and the positioning block 508 can be separated from the connecting ear 509. At this time, moving the dust collection box 501 downward can disassemble it from the bottom plate 306 to facilitate the pouring of the internal impurities. When installing, first pinch the box body and the connecting frame 507, insert the dust collection box 501 into the inside of the bottom plate 306 and then release the hand. The second spring seat 506 will push the connecting frame 507, causing the positioning block 508 to slide into the connecting ear 509, and the position of the dust collection box 501 can be quickly fixed, which is beneficial to improving the convenience during equipment maintenance.

[0033] In summary, for the laser measurement device used in furniture production, during use, first, the device is fixed on the multi-axis displacement platform of the machine tool through the mounting seat on the laser scanner 1. Then, during the scanning and measurement, the laser scanner 1 will scan and measure the board through the detection port 307;

[0034] Secondly, after measurement, start the motor 301, which drives the bottom plate 306 to rotate clockwise through the driving gear 302, the ring gear 303, the rotating shaft 304 and the connecting cover 305, so that the brush plate 308 can be moved below the lens. At this time, when the bottom plate 306 is controlled to rotate reciprocally, the surface of the lens can be automatically cleaned. During this process, the rotating shaft 304 will also push the sliding column 405 through the guiding groove 404. At this time, since the guiding strip 408 will limit the rotation of the lifting plate 407, making it only move vertically, the sliding column 405 will drive the sliding sleeve 406 to move up and down under the guidance of the inclined surface of the guiding groove 404. The lifting plate 407 will divide the inside of the fixed cylinder 409 into upper and lower chambers. Therefore, when the height of the lifting plate 407 changes, the size of the chamber will also change synchronously. And when the chamber space decreases, the air inside will be discharged through the first one-way valve 410. When the chamber space increases, it will suck the inside of the connecting cover 305 through the second one-way valve 411 and the rotating shaft 304. Therefore, the dust and impurities swept by the brush plate 308 can be sucked into the connecting cover 305 through the dust suction port 402, and the second filter plate 403 will intercept the dust and impurities. At the same time, the position of the first filter plate 401 is close to the lens of the laser scanner 1. Therefore, part of the clean external air flow can also blow to the surface of the lens, thereby improving the cleaning effect. And there are two chambers, so continuous suction can be carried out during the reciprocating rotation of the rotating shaft 304;

[0035] Then, during the rotation of the bottom plate 306, the dust collection box 501 will also be driven to rotate synchronously. Since the return spring 502 will push the support column 503, making the ejector rod 504 close to the limit convex ring 505, and the limit convex ring 505 is fixedly installed on the top cover 2, the ejector rod 504 will slide at the bottom of the limit convex ring 505, so that the second filter plate 403 can vibrate up and down. Therefore, during continuous dust suction, part of the dust and impurities can be vibrated and fallen into the lower dust collection box 501 for collection, avoiding the situation that the dust and impurities continuously adhere to the second filter plate 403 and cause blockage;

[0036] Finally, continue to rotate the bottom plate 306 clockwise after cleaning, and the cover plate 310 can be moved under the lens of the laser scanner 1. At this time, the roller 311 will synchronously move to the recessed part of the limit ring 312, and the first spring seat 309 will push the cover plate 310 to cover the bottom of the lens. Thus, during the processing of the plate, the lens of the laser scanner 1 will not be exposed to the outside and polluted, avoiding the influence of the attachment of impurities on the scanning and measurement accuracy of the laser scanner 1. And when it is necessary to disassemble and empty the dust collection box 501, just push the connecting frame 507, and the positioning block 508 can be separated from the connecting ear 509. At this time, moving the dust collection box 501 downward can disassemble it from the bottom plate 306 to empty the impurities inside. When installing, first pinch the box body and the connecting frame 507, insert the dust collection box 501 into the inside of the bottom plate 306 and then release it. The second spring seat 506 will push the connecting frame 507, so that the positioning block 508 slides into the connecting ear 509, and the dust collection box 501 can be quickly fixed.
