Description

Technical Field

[0001] This invention relates to the field of wood sawing equipment technology, specifically to a short wood scanning and optimized sawing equipment. Background Technology

[0002] In timber processing, the production process often involves sawing short pieces of wood, which refers to timber less than 500mm in length. This is because these pieces of wood sometimes have defects such as bark, bird's eye, and blue stain. Removing these defects, or grading and cross-cutting them according to their type, yields higher-grade timber. Figure 1 As shown, there is a defect on the wood. The line in the diagram indicates where the wood can be cut. This would give you a piece of wood with the defect (as a grade B board) and a piece of wood without the defect (as a grade A board). This would allow the factory to produce more high-grade boards, thus increasing its profits.

[0003] Currently, in this process, factories use a manual push-and-lift saw method. Workers hold the timber (less than 500mm) on the table, visually inspect the defect, align the cut point with the saw blade, and then push the table forward to cut the timber, obtaining the desired grade. This manual operation has the following problems: 1. No safety precautions; workers can directly touch the saw blade, and if distracted, they are prone to cutting themselves. 2. The cutting position relies entirely on the worker's feel. At high speeds, with the saw blade rotating rapidly, it's impossible for workers to measure the distance between the blade and the cut point, leading to lower yield. 3. High labor intensity; workers stand in front of the push-and-lift saw for over ten hours a day performing repetitive tasks. 4. High skill level required; a novice worker may produce half the output of a skilled worker. Because the saw blade is exposed and each piece of wood needs to be inspected on both the top and bottom surfaces to achieve the appropriate grade, workers need to be skilled, highly focused, familiar with the requirements for wood grading, and able to withstand noise from the external environment.

[0004] A search revealed that the Chinese utility model patent publication number is CN219705505U, and the patent title is "An Automatic Production Line for Defect Identification, Sawing, and Classification of Laminated Timber". The patent discloses a feeding mechanism for feeding timber, which is then conveyed to an identification mechanism I via a conveyor mechanism. After defects are identified by the identification mechanism I, the timber is conveyed to a sorting mechanism via another conveyor mechanism for sorting. The sorting mechanism supplies timber to two conveyor mechanisms. The timber strips are then conveyed to a sawing mechanism via another conveyor mechanism to cut off defects. Finally, the timber is conveyed to an identification mechanism II via another conveyor mechanism to identify color defects and then conveyed to a classification mechanism via another conveyor mechanism for final classification and storage.

[0005] The feeding, conveying, identification, sorting, sawing, and classification functions of this production line are all implemented through independent equipment, which means that each functional device needs to be equipped with a conveying mechanism. Moreover, the production line requires two sets of sawing mechanisms, identification mechanisms, and classification mechanisms starting from the sorting mechanism to ensure the efficiency of cutting and classifying the wood. The existing problem of wood defect identification and classification can only be solved by large-scale production lines. The entire production line is large in size, occupies a large area, and has high procurement, operating, and maintenance costs. Summary of the Invention

[0006] The purpose of this invention is to provide a short timber scanning and optimization sawing device to solve at least one of the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A short timber scanning and optimization sawing device includes a timber sawing device. The timber sawing device includes a frame, on which a feeding mechanism, a vision scanning mechanism, a sawing mechanism, and a pushing mechanism are provided. The feeding mechanism pushes the timber to the vision scanning mechanism. An elastic pressure roller is provided between the vision scanning mechanism and the sawing mechanism, and the elastic pressure roller presses down the timber that is pushed through.

[0009] The pushing mechanism includes linear drive mechanisms symmetrically arranged on both sides of the sawing mechanism. The linear drive mechanism is equipped with a pushing cylinder. The linear drive mechanism drives the pushing cylinder to move along the wood travel path. The piston rod of the pushing cylinder is equipped with a push plate at its end. The push plate has an extended state and a retracted state. The extended state push plate is located at the rear end of the wood, and the retracted state push plate is away from the wood travel path.

[0010] This technical solution includes a wood sawing device and a wood sorting device. The wood sawing device includes a frame, on which a feeding mechanism, a vision scanning mechanism, a sawing mechanism, and a pushing mechanism are provided. It can integrate the pushing, identification, and sawing of wood into one device. The pushing mechanism can greatly improve the cutting efficiency of wood, and there is no need to set up two separate branches to separately transport and cut the wood. While greatly improving the integration of the equipment, the working efficiency can also be guaranteed. Specifically, an elastic pressure roller is installed between the vision scanning mechanism and the sawing mechanism. This roller presses down on the wood being pushed by the feeding mechanism. The wood is pushed to the elastic pressure roller, which temporarily holds it down. A linear drive mechanism moves a pushing cylinder along the wood's path. The piston rod of the pushing cylinder has a push plate at its end, which has extended and retracted states. In the extended state, the push plate is located at the rear end of the wood; in the retracted state, it is away from the wood's path. When the push plate is extended and located at the rear end of the wood, the linear drive mechanism moves the pushing cylinder. This process drives the wood, allowing it to... The wood is pushed from the position pressed by the elastic pressure roller to the cutting position. Since there are linear drive mechanisms on both sides of the sawing mechanism, the pushing cylinders on both sides can push the wood alternately. The piston rods of the pushing cylinders also extend and retract alternately, thus avoiding obstruction to the movement of the wood pushed by the subsequent pushing plate. This device can achieve rapid pushing and cutting of wood without the need for two sets of sawing equipment. The device can improve the cutting efficiency of the equipment as a whole and solve the problems of large size, large footprint, high procurement cost, operating cost and subsequent maintenance cost of the existing production line.

[0011] Furthermore, in order to better classify the sawn wood, a wood classification device is also included. The wood classification device includes a wood conveying mechanism. On one side of the wood conveying mechanism, multiple classification cylinders are spaced apart along its length. The classification cylinders push out wood of different grades from the conveying mechanism.

[0012] Furthermore, the feeding mechanism includes a base, an inclined table on the frame, an inclined plate on the base, the inclined plate and the inclined table have the same inclination and their upper surfaces are flush, a docking notch is provided on the inclined table, and the discharge end of the base is located at the docking notch;

[0013] The inclined plate includes a material stacking area and a material discharge identification area. A baffle is provided on the lower side of the inclined plate on the base along its length. The baffle extends to the top of the inclined platform. A clearance gap is left between the baffle and the inclined platform. When the push plate on the back side of the baffle is extended, it extends from the clearance gap to the front side of the baffle so that the push plate is located at the rear end of the wood.

[0014] An inclined backing plate is provided on one side of the baffle on the base. The inclined backing plate corresponds to the stacking area. A baffle is provided on the inclined backing plate. The baffle is located between the stacking area and the discharge identification area. A discharge port is provided between the lower end of the baffle and the inclined plate. Chain drive assemblies are symmetrically provided on both sides of the base along its length. A pusher plate is provided on the chain of the chain drive assembly. The bottom layer of multiple pieces of wood in the stacking area is pushed into the discharge identification area by the pusher plate.

[0015] The vision scanning mechanism includes an opening in the discharge recognition area and vision scanning components positioned above and below the discharge recognition area. The vision scanning components include industrial cameras and a light source, with the two industrial cameras facing the opening.

[0016] The existing feeding mechanism conveys wood by setting up a conveyor below the loading mechanism. Specifically, it uses a motor-driven conveyor belt. When the wood is stacked high, the weight of all the wood is on the conveyor belt, resulting in a high conveying load and making it difficult to guarantee the stability of the equipment operation.

[0017] This technical solution features an inclined plate on the base, with a stop bar along its length on one side of the base at the lower position of the inclined plate, and an inclined backing plate on one side of the stop bar. The stop bar limits the movement of the bottom layer of wood and the moving pieces of wood. When multiple pieces of wood are stacked on the stacking area of ​​the inclined plate, gravity causes the stacked wood to lean towards the inclined backing plate, which also provides sufficient lateral support to ensure the stability of the stacked wood. The inclined backing plate has a baffle located between the stacking area and the discharge recognition area, with a discharge port between the lower end of the baffle and the inclined plate. The height of the discharge port between the baffle and the inclined plate limits the movement of only the bottom layer of wood from the stacking area to the discharge recognition area, facilitating the visual scanning component to capture and recognize the upper and lower surfaces of the wood passing through the opening. Because chain drive assemblies are symmetrically arranged on both sides of the base along its length, and pusher plates are installed on the chains of these assemblies, the bottom layer of wood in the stacking area is pushed into the discharge identification area by these pusher plates. Specifically, the chain drives the pusher plates to move, pushing the bottom layer of wood towards the discharge identification area from the rear end. The entire pushing process does not require a conveyor belt to transport the wood. Combined with the inclined plates, baffles, and inclined support plates, the wood is stacked at an incline. A baffle is installed on the base along the length of the inclined plate at its lower position. The wood slides on the inclined plate throughout the pushing process, and the baffle limits the sliding trajectory of the wood, preventing deviation even when the wood is in motion relative to the inclined plate. In summary, this device solves the problems of high conveyor load and unstable operation associated with traditional conveyor belts for stacking wood.

[0018] Furthermore, in order to provide a linear drive mechanism with a simple structure and convenient control, the linear drive mechanism includes a moving base, a slide rail, a rack and a pusher motor. The slide rail is mounted on the frame and is parallel to the wood travel path. The moving base is slidably engaged with the slide rail. The pusher motor and the pusher cylinder are both mounted on the moving base. A gear is provided on the output shaft of the pusher motor, and the gear meshes with the rack.

[0019] Furthermore, in order to provide an elastic pressure roller that can better guide and press wood, the elastic pressure roller includes a swing arm and a pressure roller. The pressure roller is located at the lower end of the swing arm and is used to apply pressure to the wood. An elastic element is inclinedly connected between the upper end of the swing arm and the frame.

[0020] Furthermore, in order to provide a saw blade mechanism that facilitates height adjustment, the sawing mechanism includes a saw blade motor, a saw lifting cylinder, a saw blade box, and a saw blade. The saw blade is disposed inside the saw blade box, which is fixed to the frame. The saw blade motor drives the saw blade to rotate. A sawing opening is provided on the inclined table. The saw lifting cylinder drives the saw blade to move up and down within the saw blade box. When the saw blade is in the raised state, the upper end of the saw blade is above the sawing opening, and when the saw blade is in the lowered state, the upper end of the saw blade is below the sawing opening.

[0021] Furthermore, in order to compress the wood during cutting, a pressing mechanism is provided on the frame directly above the sawing mechanism. The pressing mechanism includes a pressing cylinder and a pressing assembly. The pressing cylinder is mounted on the frame and drives the pressing assembly to press the wood at the sawing position on the inclined table.

[0022] Furthermore, in order to better achieve the setting of the inclined plate, the base is an inclined base, and the inclined backing plate is perpendicular to the inclined plate.

[0023] Furthermore, in order to accommodate wood of different widths in a stacked state, an adjustable backing plate is provided on the side of the base opposite to the inclined backing plate, and the distance between the adjustable backing plate and the inclined backing plate is adjustable.

[0024] Furthermore, in order to provide a specific chain and sprocket drive structure, the chain drive assembly includes a first sprocket and a second sprocket respectively disposed at both ends of the base in the length direction, a chain is provided between the first sprocket and the second sprocket, a motor is installed on the base, and the motor drives the two outermost first sprockets located on the base to rotate.

[0025] Furthermore, in order to facilitate the adaptive adjustment of the discharge port height according to the thickness of the wood, the lower end of the baffle is provided with an adjustment plate, the adjustment plate is provided with a vertical adjustment hole, and the vertical adjustment hole is fixedly installed to the baffle by bolts. The distance between the adjustment plate and the inclined plate can be adjusted by adjusting the position of the bolts in the vertical adjustment hole, and the discharge port is located between the adjustment plate and the inclined plate.

[0026] The beneficial effects of this invention are as follows: This technical solution includes a wood sawing device and a wood sorting device. The wood sawing device includes a frame, on which a feeding mechanism, a vision scanning mechanism, a sawing mechanism, and a pushing mechanism are provided. It can integrate the pushing of wood, the identification and scanning of wood, and the sawing height of wood into one device. Moreover, the setting of the pushing mechanism can greatly improve the cutting efficiency of wood, and there is no need to set up two separate branches to realize the separate conveying and cutting of wood. While greatly improving the integration of the equipment, the working efficiency can also be guaranteed. Specifically, an elastic pressure roller is installed between the vision scanning mechanism and the sawing mechanism. This roller presses down on the wood being pushed by the feeding mechanism. The wood is pushed to the elastic pressure roller, which temporarily holds it down. A linear drive mechanism moves a pushing cylinder along the wood's path. The piston rod of the pushing cylinder has a push plate at its end, which has extended and retracted states. In the extended state, the push plate is located at the rear end of the wood; in the retracted state, it is away from the wood's path. When the push plate is extended and located at the rear end of the wood, the linear drive mechanism moves the pushing cylinder. This process drives the wood, allowing it to... The wood is pushed from the position pressed by the elastic pressure roller to the cutting position. Since there are linear drive mechanisms on both sides of the sawing mechanism, the pushing cylinders on both sides can push the wood alternately. The piston rods of the pushing cylinders also extend and retract alternately, thus avoiding obstruction to the movement of the wood pushed by the subsequent pushing plate. This device can achieve rapid pushing and cutting of wood without the need for two sets of sawing equipment. The device can improve the cutting efficiency of the equipment as a whole and solve the problems of large size, large footprint, high procurement cost, operating cost and subsequent maintenance cost of the existing production line.

Detailed Implementation

[0038] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0039] Example 1:

[0040] like Figures 2-10 As shown, this embodiment provides a short wood scanning and optimization sawing device, including a wood sawing device. The wood sawing device includes a frame 1, and the frame 1 is provided with a feeding mechanism 2, a vision scanning mechanism 3, a sawing mechanism 4 and a pushing mechanism 5. The feeding mechanism 2 pushes the wood 6 to the vision scanning mechanism 3. An elastic pressure roller 7 is provided between the vision scanning mechanism 3 and the sawing mechanism 4. The elastic pressure roller 7 presses down the wood 6 that has been pushed through.

[0041] The pushing mechanism 5 includes linear drive mechanisms symmetrically arranged on both sides of the sawing mechanism 4. The linear drive mechanism is equipped with a pushing cylinder 8. The linear drive mechanism drives the pushing cylinder 8 to move along the travel path of the wood 6. The end of the piston rod 9 of the pushing cylinder 8 is equipped with a push plate 10. The push plate 10 has an extended state and a retracted state. The extended state push plate 10 is located at the rear end of the wood 6, and the retracted state push plate 10 is away from the travel path of the wood 6.

[0042] This technical solution includes a wood sawing device and a wood sorting device. The wood sawing device includes a frame 1, on which a feeding mechanism 2, a vision scanning mechanism 3, a sawing mechanism 4, and a pushing mechanism 5 are provided. It can integrate the pushing of wood 6, the identification and scanning of wood 6, and the sawing height of wood 6 into one device. The setting of the pushing mechanism 5 can greatly improve the cutting efficiency of wood 6, and there is no need to set up two separate branches to achieve separate conveying and cutting of wood 6. While greatly improving the integration of the equipment, the working efficiency can also be guaranteed. Specifically, since an elastic pressure roller 7 is provided between the visual scanning mechanism 3 and the sawing mechanism 4, the elastic pressure roller 7 presses down the wood 6 that is being pushed through. The wood 6 is pushed to the elastic pressure roller 7 by the feeding mechanism 2, and the elastic pressure roller 7 can temporarily press down the wood 6. Since the linear drive mechanism drives the pushing cylinder 8 to move along the path of the wood 6, the end of the piston rod 9 of the pushing cylinder 8 is provided with a push plate 10. The push plate 10 has an extended state and a retracted state. The extended push plate 10 is located at the rear end of the wood 6, and the retracted push plate 10 is away from the path of the wood 6. When the push plate 10 is in the extended state and located at the rear end of the wood 6, the linear drive mechanism drives the pushing cylinder 8 to move. During this process, the wood 6 is pressed down. Driven by the elastic pressure roller 7, the wood 6 is pushed from the position where it is pressed by the elastic pressure roller 7 to the cutting position. Since linear drive mechanisms are provided on both sides of the sawing mechanism 4, the pushing cylinders 8 on both sides can push the wood 6 alternately. The piston rod 9 of the pushing cylinder 8 also extends and retracts alternately, thereby avoiding obstruction to the movement of the wood 6 pushed by the subsequent pushing plate 10. This device can achieve rapid pushing and cutting of the wood 6 without the need for two sets of sawing equipment. The device can improve the cutting efficiency of the equipment as a whole and solve the problems of large size, large footprint, high procurement cost, operating cost and later maintenance cost of the existing production line.

[0043] Example 2:

[0044] This embodiment is an optimization based on the above embodiment 1.

[0045] To better classify the sawn wood, a wood classification device is also included. The wood classification device includes a wood conveying mechanism 50. Multiple classification cylinders 51 are spaced apart along the length of one side of the wood conveying mechanism 50. The classification cylinders 51 push out wood of different grades 6 from the conveying mechanism 50.

[0046] Example 3:

[0047] This embodiment is an optimization based on the above embodiment 1.

[0048] The feeding mechanism 2 includes a base 17, an inclined table 16 on the frame 1, an inclined plate 18 on the base 17, the inclined plate 18 and the inclined table 16 have the same inclination and their upper surfaces are flush, the inclined table 16 has a docking notch 19, and the discharge end of the base 17 is located at the docking notch 19.

[0049] The inclined plate 18 includes a stacking area 20 and a discharge identification area 21. A baffle 22 is provided on the lower side of the inclined plate 18 along its length. The baffle 22 extends above the inclined platform 16. A clearance gap 23 is left between the baffle 22 and the inclined platform 16. The push plate 10 located on the back side of the baffle 22 extends from the clearance gap 23 to the front side of the baffle 22 in the extended state, so that the push plate 10 is located at the rear end of the wood 6.

[0050] An inclined plate 24 is provided on one side of the baffle 22 on the base 17. The inclined plate 24 corresponds to the stacking area 20. A baffle 25 is provided on the inclined plate 24. The baffle 25 is located between the stacking area 20 and the discharge identification area 21. A discharge port 26 is provided between the lower end of the baffle 25 and the inclined plate 18. Chain drive assemblies are symmetrically provided on both sides of the base 17 along its length. A pusher plate 27 is provided on the chain 38 of the chain drive assembly. The bottom layer of wood 6 in the stacking area 20 is pushed into the discharge identification area 21 by the pusher plate 27.

[0051] The vision scanning mechanism 3 includes an opening 28 disposed on the discharge recognition area 21 and vision scanning components disposed above and below the discharge recognition area 21. The vision scanning components include industrial cameras 43 and light sources, with the two industrial cameras 43 facing the opening 28.

[0052] The existing feeding mechanism 2 conveys wood by setting a conveyor mechanism below the feeding mechanism. Specifically, it uses a motor-driven conveyor belt. When the wood is stacked high, the weight of all the wood is on the conveyor belt, resulting in a high conveying load and making it difficult to guarantee the stability of the equipment operation.

[0053] In this technical solution, since an inclined plate 18 is provided on the base 17, a baffle 22 is provided on the side of the base 17 located at the lower position of the inclined plate 18 along its length direction, and an inclined backing plate 24 is provided on the side of the base 17 located on the baffle 22. The baffle 22 limits the bottom layer and the moving wood 6. When multiple pieces of wood 6 are stacked on the stacking area 20 on the inclined plate 18, under the action of gravity, the stacked wood 6 will lean towards the inclined backing plate 24. At the same time, the inclined backing plate 24 can also provide sufficient lateral support to the wood 6 to ensure the stability of the stacked wood 6. Since the inclined plate 24 is provided with a baffle 25, which is located between the stacking area 20 and the discharge recognition area 21, and the lower end of the baffle 25 is provided with a discharge port 26 between the inclined plate 18, the height of the discharge port 26 between the baffle 25 and the inclined plate 18 can be limited so that only the bottom layer of wood 6 can be pushed from the stacking area 20 to the discharge recognition area 21, thereby facilitating the visual scanning component to capture and recognize the upper and lower surfaces of the wood 6 passing through the opening 28. Because chain drive assemblies are symmetrically arranged on both sides of the base 17 along its length, and pusher plates 27 are provided on the chains 38 of the chain drive assemblies, the bottom layer of wood 6 in the stacking area 20 is pushed into the discharge identification area 21 by the pusher plates 27. Specifically, the pusher plates 27 are moved by the chain 38, and the pusher plates 27 push the bottom layer of wood 6 from the rear end of the wood 6 towards the discharge identification area 21. The entire pushing process does not require a conveyor belt to transport the wood 6. Combined with the setting of the inclined plate 18, the baffle 22 and the inclined backing plate 24, the wood 6 is stacked at an incline. The baffle 22 is provided on the side of the base 17 located at the lower position of the inclined plate 18 along its length. During the entire pushing process, the wood 6 slides on the inclined plate 18. The baffle 22 can limit the sliding trajectory of the wood 6. Even if the wood 6 is in motion relative to the inclined plate 18, it will not deviate from its trajectory. In summary, this device solves the problems of high conveyor load and unstable operation of the equipment in the traditional conveyor belt conveying of stacked wood 6.

[0054] Preferably, to facilitate the assembly of the base 17, the base 17 includes an inclined base plate 44, on which two inclined side plates 45 are symmetrically arranged, and multiple horizontal plates 46 are spaced apart between the two inclined side plates 45. Vertical plates 47 are provided on the horizontal plates 46, and inclined plates 18 are fixedly installed on the vertical plates 47. It also includes a support base 48, the upper end of which is an inclined surface, and the inclined base plate 44 is fixedly installed on the inclined surface.

The slide rail 12 is mounted on the frame 1 and is parallel to the travel path of the wood 6. The moving base 11 is slidably engaged with the slide rail 12. The pusher motor 14 and the pusher cylinder 8 are both mounted on the moving base 11. A gear is provided on the output shaft of the pusher motor 14, and the gear meshes with the rack 13.

[0060] In order to provide an elastic pressure roller 7 that can better guide and press the wood 6, the elastic pressure roller 7 includes a swing arm 7.1 and a pressure roller 7.2. The pressure roller 7.2 is located at the lower end of the swing arm 7.1 and is used to apply pressure to the wood 6. An elastic element 7.3 is obliquely connected between the upper end of the swing arm 7.1 and the frame 1.

The saw blade 32 is disposed inside the saw blade box 31, which is fixed to the frame 1. The saw blade motor drives the saw blade 32 to rotate. A sawing opening 28 is provided on the inclined table 16. The saw lifting cylinder 30 drives the saw blade 32 to move up and down within the saw blade box 31. When the saw blade 32 is in the lifted state, its upper end is above the sawing opening 28, and when the saw blade 32 is in the lowered state, its upper end is below the sawing opening 28.

[0076] To provide a specific chain and sprocket drive structure, the chain drive assembly includes a first sprocket 36 and a second sprocket 37 respectively disposed at both ends of the base 17 along its length. A chain 38 is provided between the first sprocket 36 and the second sprocket 37. A motor 39 is mounted on the base 17, and the motor 39 drives the two outermost first sprockets 36 located on the base 17 to rotate.

[0077] Example 11:

[0078] This embodiment is an optimization based on the above embodiment 3.

[0079] To facilitate the adaptive adjustment of the height of the discharge port 26 according to the thickness of the wood 6, an adjustment plate 40 is provided at the lower end of the baffle 25. The adjustment plate 40 is provided with a vertical adjustment hole 41. The vertical adjustment hole 41 is fixedly installed to the baffle 25 by bolts. The distance between the adjustment plate 40 and the inclined plate 18 can be adjusted by adjusting the position of the bolts in the vertical adjustment hole 41. The discharge port 26 is located between the adjustment plate 40 and the inclined plate 18.

[0080] The work steps are as follows:

[0081] Workers place timber into the stacking area 20. Once the machine senses the presence of timber in the stacking area 20 via photoelectric signals, the motor 39 starts, driving the pusher plate 27 via the chain 38 to push the bottom timber 6 forward. This allows one timber 6 to be carried forward at a time for further scanning, analysis, and sawing. The machine's inclined table is designed to prevent the stacked timber 6 from falling over; it will only move forward against the inclined support plate 24 due to gravity. Furthermore, during movement, it will also move forward against the stop strip 22 due to gravity.

[0082] In the visual scanning area, as the wood passes by, the industrial camera 43 takes a picture, thus obtaining images of the upper and lower surfaces of the wood 6. The self-designed software processes and performs AI analysis on the images of the two surfaces of the wood, and after the analysis is completed, it issues a sawing command for the wood.

[0083] Upon receiving a sawing command for the piece of wood 6 on the inclined table 16, the pusher motor 14 starts, propelling the wood 6 towards the saw blade 32. To improve efficiency, this invention features two pusher motors 14. When pusher motor 14 advances and performs sawing, the next piece of wood 6 is fed into the inclined table 16. After the next piece of wood 6 is scanned, photographed, and analyzed, and also receives a sawing command, pusher motor 2 starts, pushing the next piece of wood 6 towards the saw blade 32. The pusher motors 14 advance via gears, racks 13, and slide rails 12. When pusher motor 14 rotates, the gears rotate on the rack 13, driving the entire mechanism to move at high speed on the slide rails 12. Thus, the two pusher motors 14 alternately start and stop, significantly improving production efficiency. A pusher cylinder 8 is installed together with the pusher motor 14. When the pusher motor 14 moves towards the saw blade 32, the piston rod 9 of the pusher cylinder 8 extends, thus pushing the wood 6 towards the saw blade 32 at high speed. When the pusher motor 14 returns to the ready-to-start position, the piston rod 9 of the pusher cylinder 8 retracts, so as not to collide with the next piece of wood 6 that is moving.

[0084] In the sawing area, the saw blade 32 is installed below the inclined table 16. Only when it reaches the sawing position does the lifting cylinder 30 extend, thereby lifting the saw blade 32 above the inclined table 16. After sawing the wood 6, the saw blade 32 descends below the inclined table 16, thus ensuring production safety. When cutting the wood, the clamping cylinder 33 extends, driving the clamping component 34 to clamp the wood. Then, the lifting cylinder 30 lifts the saw blade 32, which is rotating at high speed driven by the saw blade motor, to saw the wood. When the saw blade 32 descends below the inclined table 16, the photoelectric sensor detects the saw blade 32 returning to its original position. Then, the pusher motor 14 pushes the wood 6 to the next sawing position, preventing the wood from hitting the saw blade 32.

[0085] After the wood 6 is cut, it will be pushed out of the inclined table 16 by the pusher motor 14 and enter the wood conveying mechanism 50. Multiple sets of sorting cylinders 51 are installed on one side of the wood conveying mechanism 50. Different grades of wood will be pushed out by sorting cylinders 51 at different positions according to the settings, thereby realizing the function of automatic sorting after sawing and replacing manual sorting.

[0086] The advantages of this equipment are as follows:

[0087] 1. This equipment can achieve automatic scanning, automatic sawing, and automatic sorting functions.

[0088] 2. Compared with existing technologies, it can greatly reduce the occurrence of workplace accidents.

[0089] 3. Compared with existing technologies, the present invention obtains more reasonable sawing results and higher yield by acquiring wood photos and analyzing them with AI large model.

[0090] 4. This equipment can operate continuously, even during night shifts; while existing equipment cannot operate during night shifts due to worker fatigue and safety concerns.

[0091] 5. This equipment greatly reduces repetitive labor for workers and significantly reduces the skill level required of workers.

[0092] 6. This equipment makes it easier to achieve overall factory automation. With existing manual sawing methods, it is difficult to achieve seamless integration before and after automation.

[0093] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
