Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, and more particularly to a wood processing board cutting robotic arm capable of collecting wood chips. Background Technology

[0002] In the wood processing process, board cutting is an important step. As a mechanical device that can simulate the function of a human arm, it has unique operational flexibility and is widely used in the wood processing field for cutting boards. It consists of multiple links and joints, and through the drive and control of components such as motors, reducers, and sensors, it can achieve various complex spatial movements. It has high-precision positioning capabilities and can accurately reach and manipulate target objects.

[0003] Currently, most robotic arms for cutting wood panels on the market are designed with a focus on simplicity, primarily limited to basic cutting operations. However, due to the characteristics of wood, a large amount of fine sawdust is inevitably generated during the cutting process. Existing robotic arms often lack effective mechanisms for collecting and processing this sawdust, causing it to scatter and accumulate in the work environment. Over time, this untreated sawdust not only poses a potential pollution risk to the environment but may also cause safety hazards such as fires. More seriously, the flying sawdust can severely affect the air quality in the work area, thus threatening the respiratory health of workers and increasing the risk of occupational diseases. To address these problems, this invention proposes a robotic arm for cutting wood panels that can collect sawdust. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wood-processing board-cutting robotic arm that can collect wood chips, thereby ensuring a clean working environment, reducing the risk of fire, guaranteeing air quality, and providing some protection for the respiratory health of operators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wood processing board cutting robotic arm capable of collecting wood chips includes a robotic arm body, a power component mounted on the robotic arm body, a linkage structure mounted on the power component, a collection structure mounted on the linkage structure, and the linkage structure and the collection structure cooperating with each other to collect wood chips. A feeding structure is mounted on the collection structure, and a connecting structure that limits the feeding structure is mounted on the linkage structure. An elastic structure is provided inside the connecting structure.

[0007] The linkage structure includes a mounting base installed at the bottom of the power assembly. A first rotating shaft and several second rotating shafts are rotatably connected to the mounting base. A driving gear and a driven gear are fixedly connected to the outer walls of the first rotating shaft and the second rotating shaft, respectively. The driving gear and all the driven gears mesh with each other. The top end of the first rotating shaft is fixedly connected to the output end of the motor inside the power assembly.

[0008] The collection structure includes a mounting cover fixedly connected to the bottom of the mounting base, and fan blades fixedly connected to the outer wall of the second rotating shaft. Several conveying pipes are fixedly connected to the top of the mounting base, and the conveying pipes are interconnected with the interior of the mounting cover.

[0009] Preferably, the diameter of the driving gear is larger than the diameter of the driven gear, and a cutting blade is fixedly connected to the outer wall of the first rotating shaft.

[0010] Preferably, the end of the conveying pipe is connected to an external collection box, the fan blade is located inside the mounting cover, and when the fan blade rotates, the wood chips enter the mounting cover through the outside and are then transported to the collection box through the conveying pipe.

[0011] Preferably, a protective cover is fixedly connected to the bottom of the mounting base, and both the driving gear and the driven gear are located inside the protective cover.

[0012] Preferably, the protective cover is provided with a plurality of through holes, and the conveying pipe passes through the adjacent through holes.

[0013] Preferably, the feeding structure includes a plurality of connecting sleeves fixedly connected to the mounting cover, all of the connecting sleeves being distributed around the outer wall of the mounting cover, and a feeding pipe being slidably connected inside the connecting sleeves, with the feeding port of the feeding pipe connected to a collecting cover.

[0014] Preferably, the feed pipe is L-shaped, the end of the collecting hood is frustum-shaped, and the feed inlet diameter of the collecting hood is larger than its own discharge outlet diameter.

[0015] Preferably, the connection structure includes a plurality of first mounting plates fixedly connected to the top of the mounting base. A mounting sleeve is fixedly connected to the first mounting plate. A connecting rod is slidably connected inside the mounting sleeve. A second mounting plate is fixedly connected to the end of the connecting rod away from the mounting sleeve. A collar is fixedly connected to the bottom of the second mounting plate. The collar is fixedly connected to the nearby feed pipe.

[0016] Preferably, the elastic structure includes an anti-detachment block fixedly connected to the connecting rod, a return spring fixedly connected to the anti-detachment block, and the end of the return spring away from the anti-detachment block fixedly connected to the mounting sleeve.

[0017] Preferably, the anti-detachment block is slidably connected to the mounting sleeve, and the reset spring is located inside the mounting sleeve.

[0018] Compared with the prior art, the present invention provides a board cutting robotic arm for wood processing that can collect wood chips, and has the following beneficial effects:

[0019] 1. This wood-processing board-cutting robotic arm, capable of collecting wood chips, employs a linkage and collection structure. When the power unit drives the first rotating shaft to rotate, the first rotating shaft drives the cutting blade to rotate, enabling the cutting blade to cut the board. Simultaneously, with the cooperation of the drive and driven gears, the second rotating shaft drives the fan blade to rotate, creating a negative pressure state inside the mounting cover. The fine wood chips generated during cutting enter the mounting cover through the feeding structure and are then discharged into the external collection box through the conveying pipe. This ensures the cleanliness of the working environment, reduces the risk of fire, and maintains air quality, providing some protection for the respiratory health of the operators.

[0020] 2. This wood processing board cutting robotic arm, capable of collecting wood chips, incorporates a feeding structure, a connecting structure, and a spring-loaded structure. When the robotic arm body cuts the board with the cutting blade, the collecting hood near the board is compressed by the board, automatically pushing the feeding pipe to retract within the connecting sleeve. This provides a certain range of flexible adjustment, preventing the collecting hood from obstructing the cutting process. During the retraction of the feeding pipe, the collar compresses the return spring through the second mounting plate and connecting rod. When the compressive force on the collecting hood disappears, the spring-loaded hood automatically returns to its original position, facilitating continuous collection of fine wood chips generated during cutting and ensuring the applicability of the device.

[0021] 3. This wood processing board cutting robot arm that can collect wood chips, by setting up a protective cover and through holes, allows the drive gear and driven gear to be located inside the protective cover, so that the protective cover can shield and protect the drive gear and driven gear, preventing wood chips from hindering the rotation of the drive gear and driven gear, thus ensuring the service life of the device. Since the conveying pipe runs through the through holes, the wood chips that enter the mounting cover through the feeding structure can be smoothly transferred to the collection box inside the outside without affecting the rotation of the drive gear and driven gear, ensuring that the device can work normally.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Example 1: Refer to Figure 1-6 A wood processing board cutting robot arm capable of collecting wood chips includes a robot arm body 1, a power component 2 installed on the robot arm body 1, a linkage structure 3 installed on the power component 2, a collection structure 4 provided on the linkage structure 3, and the linkage structure 3 and the collection structure 4 cooperate with each other to collect wood chips. A feeding structure 6 is installed on the collection structure 4, and a connecting structure 7 is installed on the linkage structure 3 to limit the feeding structure 6. An elastic structure 8 is provided inside the connecting structure 7.

[0034] The linkage structure 3 includes a mounting base 301 installed at the bottom of the power assembly 2. A first rotating shaft 302 and several second rotating shafts 303 are rotatably connected to the mounting base 301. A driving gear 304 and a driven gear 305 are fixedly connected to the outer walls of the first rotating shaft 302 and the second rotating shaft 303, respectively. The driving gear 304 and all the driven gears 305 mesh with each other. The top end of the first rotating shaft 302 is fixedly connected to the output end of the motor inside the power assembly 2.

[0035] The collecting structure 4 includes a mounting cover 401 fixedly connected to the bottom of the mounting base 301, and a fan blade 402 fixedly connected to the outer wall of the second rotating shaft 303. Several conveying pipes 403 are fixedly connected to the top of the mounting base 301, and the conveying pipes 403 are interconnected with the interior of the mounting cover 401.

[0036] In this invention, the diameter of the driving gear 304 is larger than the diameter of the driven gear 305. A cutting blade 9 is fixedly connected to the outer wall of the first rotating shaft 302. By setting the diameter of the driving gear 304 to be larger than the diameter of the driven gear 305, when the motor inside the power assembly 2 drives the first rotating shaft 302 to rotate, the second rotating shaft 303 can quickly drive the fan blade 402 to rotate under the cooperation of the driving gear 304 and the driven gear 305, thereby improving the suction force inside the device and facilitating the collection and processing of wood chips.

[0037] In this invention, the end of the conveying pipe 403 is connected to the external collection box, and the fan blade 402 is located inside the mounting cover 401. When the fan blade 402 rotates, the wood chips enter the mounting cover 401 through the outside and are then transported to the collection box through the conveying pipe 403. By setting the conveying pipe 403, it is convenient to transfer and process the wood chips collected by the mounting cover 401.

[0038] In this invention, a protective cover 5 is fixedly connected to the bottom of the mounting base 301. The driving gear 304 and the driven gear 305 are both located inside the protective cover 5. The protective cover 5 is provided with several through holes 501. The conveying pipe 403 passes through the adjacent through holes 501. By setting the protective cover 5 and the through holes 501, since the driving gear 304 and the driven gear 305 are both located inside the protective cover 5, the protective cover 5 can shield and protect the driving gear 304 and the driven gear 305, preventing sawdust from hindering the rotation of the driving gear 304 and the driven gear 305, and ensuring the service life of the device. Since the conveying pipe 403 passes through the through holes 501, the sawdust that enters the mounting cover 401 through the feeding structure 6 can be smoothly transferred to the collection box inside the outside without affecting the rotation of the driving gear 304 and the driven gear 305, ensuring that the device can work normally.

[0039] In this invention, the feeding structure 6 includes several connecting sleeves 601 fixedly connected to the mounting cover 401. All the connecting sleeves 601 are distributed around the outer wall of the mounting cover 401. A feeding pipe 602 is slidably connected inside the connecting sleeve 601. A collecting cover 603 is connected to the inlet of the feeding pipe 602. The feeding pipe 602 is L-shaped, and the end of the collecting cover 603 is frustum-shaped. The inlet diameter of the collecting cover 603 is larger than its outlet diameter. By setting the connecting sleeves 601 and the feeding pipe 602, and designing the connecting sleeves 601 and the feeding pipe 602 to surround the mounting cover 401, it is convenient to collect and process the wood chips generated when the cutting blade 9 cuts the board from multiple angles, ensuring the cleanliness of the working environment.

[0040] Example 2: Refer to Figure 1-8 A wood processing board cutting robot arm capable of collecting wood chips includes a robot arm body 1, a power component 2 installed on the robot arm body 1, a linkage structure 3 installed on the power component 2, a collection structure 4 provided on the linkage structure 3, and the linkage structure 3 and the collection structure 4 cooperate with each other to collect wood chips. A feeding structure 6 is installed on the collection structure 4, and a connecting structure 7 is installed on the linkage structure 3 to limit the feeding structure 6. An elastic structure 8 is provided inside the connecting structure 7.

[0041] The linkage structure 3 includes a mounting base 301 installed at the bottom of the power assembly 2. A first rotating shaft 302 and several second rotating shafts 303 are rotatably connected to the mounting base 301. A driving gear 304 and a driven gear 305 are fixedly connected to the outer walls of the first rotating shaft 302 and the second rotating shaft 303, respectively. The driving gear 304 and all the driven gears 305 mesh with each other. The top end of the first rotating shaft 302 is fixedly connected to the output end of the motor inside the power assembly 2.

[0042] The collecting structure 4 includes a mounting cover 401 fixedly connected to the bottom of the mounting base 301, and a fan blade 402 fixedly connected to the outer wall of the second rotating shaft 303. Several conveying pipes 403 are fixedly connected to the top of the mounting base 301, and the conveying pipes 403 are interconnected with the interior of the mounting cover 401.

[0043] In this invention, the diameter of the driving gear 304 is larger than the diameter of the driven gear 305. A cutting blade 9 is fixedly connected to the outer wall of the first rotating shaft 302. By setting the diameter of the driving gear 304 to be larger than the diameter of the driven gear 305, when the motor inside the power assembly 2 drives the first rotating shaft 302 to rotate, the second rotating shaft 303 can quickly drive the fan blade 402 to rotate under the cooperation of the driving gear 304 and the driven gear 305, thereby improving the suction force inside the device and facilitating the collection and processing of wood chips.

[0044] In this invention, the end of the conveying pipe 403 is connected to the external collection box, and the fan blade 402 is located inside the mounting cover 401. When the fan blade 402 rotates, the wood chips enter the mounting cover 401 through the outside and are then transported to the collection box through the conveying pipe 403. By setting the conveying pipe 403, it is convenient to transfer and process the wood chips collected by the mounting cover 401.

[0045] In this invention, a protective cover 5 is fixedly connected to the bottom of the mounting base 301. The driving gear 304 and the driven gear 305 are both located inside the protective cover 5. The protective cover 5 is provided with several through holes 501. The conveying pipe 403 passes through the adjacent through holes 501. By setting the protective cover 5 and the through holes 501, since the driving gear 304 and the driven gear 305 are both located inside the protective cover 5, the protective cover 5 can shield and protect the driving gear 304 and the driven gear 305, preventing sawdust from hindering the rotation of the driving gear 304 and the driven gear 305, and ensuring the service life of the device. Since the conveying pipe 403 passes through the through holes 501, the sawdust that enters the mounting cover 401 through the feeding structure 6 can be smoothly transferred to the collection box inside the outside without affecting the rotation of the driving gear 304 and the driven gear 305, ensuring that the device can work normally.

[0046] In this invention, the feeding structure 6 includes several connecting sleeves 601 fixedly connected to the mounting cover 401. All the connecting sleeves 601 are distributed around the outer wall of the mounting cover 401. A feeding pipe 602 is slidably connected inside the connecting sleeve 601. A collecting cover 603 is connected to the inlet of the feeding pipe 602. The feeding pipe 602 is L-shaped, and the end of the collecting cover 603 is frustum-shaped. The inlet diameter of the collecting cover 603 is larger than its outlet diameter. By setting the connecting sleeves 601 and the feeding pipe 602, and designing the connecting sleeves 601 and the feeding pipe 602 to surround the mounting cover 401, it is convenient to collect and process the wood chips generated when the cutting blade 9 cuts the board from multiple angles, ensuring the cleanliness of the working environment.

[0047] In this invention, the connecting structure 7 includes several first mounting plates 701 fixedly connected to the top of the mounting base 301. A mounting sleeve 702 is fixedly connected to each first mounting plate 701. A connecting rod 703 is slidably connected inside the mounting sleeve 702. A second mounting plate 704 is fixedly connected to the end of the connecting rod 703 away from the mounting sleeve 702. A collar 705 is fixedly connected to the bottom of the second mounting plate 704 and is fixedly connected to the nearby feed pipe 602. The elastic structure 8 includes an anti-detachment block 801 fixedly connected to the connecting rod 703. A return spring 802 is fixedly connected to the anti-detachment block 801. The end of the return spring 802 away from the anti-detachment block 801 is fixedly connected to the mounting sleeve 702. The anti-detachment block 801 and the mounting sleeve 702 are slidably connected, and the return spring 802 is located within the mounting sleeve. Inside 702, by setting an anti-detachment block 801 and a return spring 802, when the robotic arm body 1 cuts the board with the cutting blade 9, the collecting cover 603 near the board is squeezed by the board and can automatically push the feeding pipe 602 to retract inside the connecting sleeve 601. It has a certain range of flexible adjustment, thereby avoiding the collecting cover 603 from obstructing the cutting process of the cutting blade 9. When the feeding pipe 602 retracts, the collar 705 squeezes the return spring 802 through the second mounting plate 704 and the connecting rod 703. When the squeezing force on the collecting cover 603 disappears, the elastic force of the return spring 802 makes the collecting cover 603 automatically return to its original position, thereby facilitating the continuous collection and processing of fine wood chips generated by the cutting blade 9, ensuring the applicability of the device.

[0048] Working principle: When the power component 2 drives the first rotating shaft 302 to rotate, the first rotating shaft 302 drives the cutting blade 9 to rotate, so that the cutting blade 9 can cut the board. At the same time, with the cooperation of the driving gear 304 and the driven gear 305, the second rotating shaft 303 drives the fan blade 402 to rotate, thereby creating a negative pressure state inside the mounting cover 401. The fine wood chips generated by the cutting blade 9 during cutting enter the mounting cover 401 through the collecting cover 603, the feeding pipe 602 and the connecting sleeve 601, and are then discharged into the collection box outside through the conveying pipe 403.

[0049] When the robotic arm 1 cuts the board with the cutting blade 9, the collecting cover 603 near the board is squeezed by the board and can automatically push the feeding pipe 602 to retract inside the connecting sleeve 601. It has a certain range of flexible adjustment, so as to avoid the collecting cover 603 from obstructing the cutting process of the cutting blade 9. When the feeding pipe 602 retracts, the collar 705 squeezes the return spring 802 through the second mounting plate 704 and the connecting rod 703. When the squeezing force on the collecting cover 603 disappears, the elastic force of the return spring 802 makes the collecting cover 603 automatically return to its original position, so as to facilitate the continuous collection and processing of the fine wood chips generated by the cutting blade 9.
