Description

Technical Field

[0001] The invention relates to the technical field of wood processing, in particular to multi-wavelength laser composite wood layer cutting equipment. Background Art

[0002] In the field of wood processing, traditional cutting technologies such as sawing and milling have many limitations. Mechanical tool cutting is prone to large processing errors, resulting in rough cutting edges, requiring a large number of subsequent grinding processes, and severe tool wear. Frequent replacement increases production costs. Single-wavelength laser cutting equipment is also difficult to meet diverse processing needs. For wood with higher hardness, carbonization and burning are prone to occur, affecting the quality of the finished product. For softer or thinner wood, the heat-affected zone may be too large to cause material deformation. In addition, traditional equipment is inefficient and difficult to guarantee accuracy when processing complex surfaces and fine structures. It is difficult to adapt to the personalized and high-precision processing needs of modern furniture manufacturing, wood craft carving and other industries. At the same time, these devices have a low degree of automation and a high dependence on manual operation, which not only increases labor costs, but also easily leads to unstable processing quality due to operational errors. Therefore, the development of a high-precision, high-efficiency, highly adaptable and highly automated wood cutting equipment has become a problem that the industry needs to solve.

The number of the second guide rods 14 is two and they are symmetrically distributed on both sides of the second electric telescopic rod 15.

[0036] The cutting mechanism includes a first electric telescopic rod 10, a first guide rod 11, a mounting plate 9, a guide rail 22, a second slider 25, a multi-wavelength laser module 26, a second driving motor 23 and a second threaded rod 24.

[0037] The clamping mechanism includes a third support plate 27, a first adjusting bolt 28, a third guide rod 29, a first L-shaped clamping plate 30, a first limiting member 31, a first limiting sleeve 32, a second adjusting bolt 33, a fourth guide rod 34, a second limiting member 35, a second L-shaped clamping plate 36 and a second limiting sleeve 37. The rear surface of the support rod 7 is fixedly connected to the third support plate 27. The inner walls at both ends of the third support plate 27 are threadedly connected to the first adjusting bolt 28. The lower end of the first adjusting bolt 28 is fixedly connected to the first limiting member 31.

[0038] Working principle: A mechanical positioning system is constituted by the base 1, the support plate, the threaded rod transmission, the electric telescopic rod and the guide rail 22 slider, which is responsible for the three-dimensional space positioning of the cutting mechanism and the wood. The multi-wavelength laser module 26 integrates three wavelengths of ultraviolet, green and infrared. The wavelength switching, power modulation and scanning trajectory control are realized through the control system. The control device 12 is based on a PLC or an industrial computer, and integrates a motion control algorithm, a laser parameter matching model and an adaptive cutting strategy. During operation, the operator places the wood board on the rotating roller 20, and the second electric telescopic rod 15 drives the push plate 16 to push the board to the clamping area. Rotate the first adjusting bolt 28 to move the first L-shaped clamping plate 30 downward until the lower surface of the second L-shaped clamping plate 36 contacts the upper surface of the board to achieve longitudinal clamping. Rotate the second adjusting bolt 33 to drive the second L-shaped clamping plate 36 to slide along the fourth guide rod 34 to achieve side clamping of the board.

[0039] After the operator inputs the wood parameters and cutting requirements through the control device 12, the work starts. The first driving motor 4 drives the first fixing member 6 and the support rod 7 to move horizontally through the first threaded rod 5 transmission to achieve horizontal positioning. The first electric telescopic rod 10 drives the mounting plate 9 and the guide rail 22 to move up and down to achieve vertical positioning. The second driving motor 23 drives the second slider 25 to slide in the guide rail 22 through the second threaded rod 24 to achieve longitudinal positioning. During cutting, the surface layer cutting uses ultraviolet laser to directly break the wood molecular bonds through photochemical action. The middle layer cutting uses green laser to vaporize the wood through photothermal effect. The deep layer cutting uses infrared laser to penetrate. The control system decomposes the total cutting depth into multiple sub-tasks according to the wood density gradient model. When cutting adjacent layers, the laser power increases step by step and the scanning speed decreases.
