Description

Technical Field

[0001] The present invention relates to the technical field of wood processing equipment, and specifically to a multi-axis linkage laser cutting machine for wood boards based on a high-precision gearbox. Background Art

[0002] In the field of wood processing, laser cutting machines are widely used due to advantages such as high processing precision and high speed. However, traditional laser cutting machines for wood boards have many technical bottlenecks. On the one hand, the accuracy of the transmission system is insufficient. Ordinary belt or gear transmission is prone to problems such as slipping and excessive gaps, resulting in deviation of the cutting trajectory and making it difficult to meet the requirements of complex patterns and high-precision processing. On the other hand, the multi-axis linkage control is not flexible enough, and it is impossible to accurately adjust the relative position between the laser head and the board, making it difficult to adapt to wood boards of different thicknesses and shapes. In addition, a large amount of smoke and dust generated during the cutting process will not only affect the laser transmission efficiency, reduce the cutting quality, but also pose a threat to the health of operators. Existing suction devices often have problems such as insufficient collection and low dust removal efficiency. At the same time, the heat dissipation performance of the equipment during long-term operation is poor, which is likely to cause overheating and wear of the transmission components, shortening the service life of the equipment. Therefore, a wood board laser cutting device that can achieve high-precision multi-axis linkage, efficient smoke and dust removal, and stable and reliable operation is needed to improve the quality and efficiency of wood processing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] As Figure 1-8 shown, the embodiment of the present invention provides a multi-axis linkage laser cutter for wood boards based on a high-precision gearbox, including a bottom plate 1. Four corner points on the upper part of the bottom plate 1 are provided with vertically upward support rods 3. The upper ends of the support rods 3 are fixedly connected with a top plate 4. First guide rails 5 are respectively arranged near the left and right sides of the lower surface of the top plate 4. A laser cutting transmission mechanism is arranged inside the first guide rails 5 in the direction towards the center. A smoke suction mechanism is arranged at the upper end of the bottom plate 1. A placement plate 17 is fixedly connected to the middle of the upper end of the bottom plate 1. A control device 40 is arranged at the upper end of the top plate 4. The placement plate 17 is fixed in the middle of the bottom plate 1 and is used to carry the wood board to be cut, providing a stable placement plane, ensuring that the position of the board is fixed during the cutting process, and avoiding affecting the cutting accuracy due to shaking. The control device 40 is installed at the upper end of the top plate 4 and is the brain of the device, used to receive the cutting parameters input by the operator.

[0029] The laser cutting transmission mechanism includes a first slider 8, a first drive motor 6, a first threaded rod 7, a gear box body 9, a second drive motor 21, a first sprocket 22, a transmission chain 23, a second sprocket 24, a high-precision gear reducer 25, a rotating shaft 26, a rotating disk 27, a second guide rail 28, a third drive motor 29, a second threaded rod 30, a second slider 31, a second mounting plate 32, a fourth drive motor 33, a connecting block 34, a guide rod 35, a third mounting plate 36, a laser cutting module 37, a fourth mounting plate 38, a fifth mounting plate 41, a bolt 39 and a third threaded rod 42.

[0030] The first slider 8 is fixedly connected to the gear box body 9 toward the center, the top inner wall of the gear box body 9 is fixedly connected to the second drive motor 21, the output end of the second drive motor 21 is fixedly connected to the first sprocket 22, the outer surface of the first sprocket 22 is meshed with the transmission chain 23, and the end of the transmission chain 23 away from the first sprocket 22 is meshed with the second sprocket 24. The high-precision gear reducer 25 is located at the rear end of the second sprocket 24, and the output end of the high-precision gear reducer 25 is located directly below. The lower end of its output end is fixedly connected to the rotating disk 27. The gear box body 9 and the second drive motor 21 transmit the motor power to the high-precision gear reducer 25 through the transmission combination of the first sprocket 22, the transmission chain 23, and the second sprocket 24, thereby reducing the speed and increasing the torque, ensuring the stability and accuracy of the rotation of the rotating disk 27, corresponding to the circumferential positioning function of the Y-axis, the core transmission component of the high-precision gear reducer 25, and achieves precise deceleration through gear meshing to ensure the accuracy of the rotation angle of the rotating disk 27.

[0031] The lower end of the rotating disk 27 is fixedly connected to the second guide rail 28, and the second guide rail 28 is eccentrically arranged relative to the central axis of the rotating disk 27. The lower surface of the second guide rail 28 is slidably connected to the second slider 31, and the lower end of the second slider 31 is fixedly connected to the second mounting plate 32.

The outer surface of the second threaded rod 30 is threadedly connected to the second slider 31.

The third driving motor 29 and the second threaded rod 30 drive the threaded rod to rotate through the motor, driving the second slider 31 to slide on the guide rail, accurately controlling the position of the laser cutting module 37 in the Z-axis direction, for adjusting the distance between the laser beam and the surface of the plate to ensure accurate cutting depth.

[0032] The right side of the second mounting plate 32 is fixedly connected to the fifth mounting plate 41. The upper center of the fifth mounting plate 41 is fixedly connected to the fourth driving motor 33. The output end of the fourth driving motor 33 is fixedly connected to the third threaded rod 42. The outer surface of the third threaded rod 42 is threadedly connected to the connecting block 34. The motor drives the threaded rod to rotate, causing the connecting block 34 to move up and down along the threaded rod, further precisely controlling the vertical position of the laser cutting module 37. The upper end of the connecting block 34 is fixedly connected to the guiding rod 35. The number of guiding rods 35 is two and they are symmetrically distributed on both sides of the third threaded rod 42. The left side of the connecting block 34 is fixedly connected to the third mounting plate 36. The laser cutting module 37 is located at the lower end of the third mounting plate 36. The front end of the third mounting plate 36 is fixedly connected to the fourth mounting plate 38 by bolts 39. The guiding rods 35 are symmetrically distributed on both sides of the third threaded rod 42, providing guidance for the up and down movement of the connecting block 34, preventing deviation, and ensuring the linearity and accuracy of the vertical movement of the laser module. The third mounting plate 36 and the fourth mounting plate 38 fix the laser cutting module 37, and the connection by bolts 39 ensures firm installation of the module, avoiding vibration during cutting from affecting the laser emission accuracy.

[0033] A heat dissipation through-hole plate 18 is provided at the front end of the gearbox body 9. The rear end of the gearbox body 9 is fixedly connected to a first mounting plate 19. The center of the first mounting plate 19 is provided with an integrated fan 20. The heat dissipation through-hole plate 18 is located at the front end of the gearbox, providing a heat dissipation channel for the internal heat to dissipate through air convection. The integrated fan 20 is installed at the rear end of the gearbox, actively sending air to accelerate air flow and forcibly cooling the transmission components inside the gearbox, preventing component wear or a decrease in transmission accuracy due to high temperature, and extending the service life of the equipment.

[0034] The smoke extraction mechanism includes a first suction pipe 10, a transverse suction pipe 11, a longitudinal suction pipe 12, a second suction pipe 13, a suction bell mouth 14, a mounting box 15, a negative pressure device 2, and a guiding cover 16.

[0035] Embodiment 2

[0036] As Figure 1-8As shown in the figure, an embodiment of the present invention provides a multi-axis linkage laser cutting machine for wood boards based on a high-precision gearbox, including a bottom plate 1. Vertical support rods 3 are provided at the four corner points on the upper part of the bottom plate 1. The upper ends of the support rods 3 are fixedly connected to a top plate 4. First guide rails 5 are respectively provided on the lower surface of the top plate 4 near the left and right sides. A laser cutting transmission mechanism is arranged inside the first guide rails 5 in the direction towards the center. A smoke suction mechanism is arranged on the upper end of the bottom plate 1. A placement plate 17 is fixedly connected to the middle of the upper end of the bottom plate 1. A control device 40 is arranged on the upper end of the top plate 4. The placement plate 17 is fixed in the middle of the bottom plate 1 and is used to carry the wood board to be cut, providing a stable placement plane to ensure that the position of the board is fixed during cutting and avoid affecting the cutting accuracy due to shaking. The control device 40 is installed on the upper end of the top plate 4 and is the "brain" of the equipment, used to receive the cutting parameters input by the operator.

[0037] The laser cutting transmission mechanism includes a first slider 8, a first driving motor 6, a first threaded rod 7, a gearbox body 9, a second driving motor 21, a first sprocket 22, a transmission chain 23, a second sprocket 24, a high-precision gear reducer 25, a rotating shaft 26, a rotating disk 27, a second guide rail 28, a third driving motor 29, a second threaded rod 30, a second slider 31, a second mounting plate 32, a fourth driving motor 33, a connecting block 34, a guide rod 35, a third mounting plate 36, a laser cutting module 37, a fourth mounting plate 38, a fifth mounting plate 41, bolts 39 and a third threaded rod 42.

[0038] The smoke suction mechanism includes a first suction pipe 10, a transverse suction pipe 11, a longitudinal suction pipe 12, a second suction pipe 13, a suction bell mouth 14, a mounting box 15, a negative pressure device 2 and a guide cover 16.

[0039] Both sides of the upper end of the bottom plate 1 are fixedly connected to the mounting box 15. The upper end of the mounting box 15 is fixedly connected to the guide cover 16. The inner wall of the mounting box 15 is fixedly connected to the suction bell mouth 14. The mounting box 15 and the guide cover 16 are fixed on both sides of the bottom plate 1. The inner wall of the mounting box 15 is connected to the suction bell mouth 14. The guide cover 16 guides the smoke generated by cutting to gather towards the suction bell mouth 14, improving the smoke collection efficiency. The number of suction bell mouths 14 is multiple and they are horizontally distributed. The lower end of the suction bell mouth 14 is communicated with the second suction pipe 13. The lower end of the second suction pipe 13 is communicated with the longitudinal suction pipe 12. The second suction pipe 13 and the longitudinal suction pipe 12 converge the smoke sucked by the suction bell mouth 14 and transmit it longitudinally, forming an orderly smoke flow path to avoid the diffusion of smoke inside the equipment.

[0040] The front end of the longitudinal suction pipe 12 is connected to the transverse suction pipe 11. The lower end of the middle part of the transverse suction pipe 11 is connected to the first suction pipe 10. The rear end of the first suction pipe 10 is fixedly connected to the negative pressure device 2. The upper end of the negative pressure device 2 is fixedly connected to the lower end of the bottom plate 1. The transverse suction pipe 11 and the first suction pipe 10 collect the longitudinally transmitted soot and convey it to the negative pressure device 2 through the first suction pipe 10.

[0041] Working principle: After the operator fixes the wood board on the placement plate 17 in the middle of the bottom plate 1 and inputs the cutting parameters through the control device 40, the first driving motor 6 starts and drives the first threaded rod 7 to rotate, driving the first slider 8 to slide horizontally on the first guide rail 5, so that the laser cutting module 37 moves along the X-axis to the initial position. At the same time, the second driving motor 21 drives the high-precision gear reducer 25 to drive the rotating disk 27 to rotate through the first sprocket 22, the transmission chain 23 and the second sprocket 24 to achieve the circumferential positioning of the Y-axis.

[0042] The third driving motor 29 drives the second slider 31 to slide on the eccentrically arranged second guide rail 28 through the second threaded rod 30 to achieve the longitudinal fine adjustment of the Z-axis. The fourth driving motor 33 drives the connecting block 34 to move up and down along the guide rod 35 through the third threaded rod 42 to accurately control the distance between the laser cutting module 37 and the board. Subsequently, the laser cutting module 37 emits a high-energy laser beam to melt or vaporize the wood board according to the preset trajectory. The soot generated during the cutting process is inhaled through the suction bell mouth 14 in the installation box 15, and is discharged from the system by the negative pressure device 2 through the second suction pipe 13, the longitudinal suction pipe 12, the transverse suction pipe 11 and the first suction pipe 10. The control device 40 monitors the motion states of each axis in real time and adjusts the motor parameters through the encoder feedback to ensure the cutting accuracy. The heat dissipation through-hole plate 18 at the front end and the integrated fan 20 at the rear end of the gearbox body 9 maintain the temperature stability of the transmission system. After the cutting is completed, the equipment automatically resets, and the operator cleans the residual debris to complete the entire work process.
