Embodiments

[0033] Referring to Figs. 1-2 The high-precision laser cutting device aims to realize efficient and accurate cutting of the material to be cut. The device comprises a marble material machine table 1, and a marble material adsorption table 2 is arranged on the machine table 1. The close combination of the adsorption table 2 and the machine table 1 forms a stable and flat working platform, and the horizontal deviation of the platform is ±0.02mm, which provides an ideal operating environment for subsequent cutting operations.

[0034] The selection of marble material not only endows the machine table 1 and the adsorption table 2 with high-strength characteristics, ensuring that the structure remains stable under long-time and high-load working conditions, but also effectively resists the adverse effects of temperature changes on cutting accuracy due to its low thermal expansion coefficient. At the same time, the excellent stability of marble greatly reduces the interference of environmental vibration on the cutting process, providing a solid physical basis for high-precision cutting.

[0035] The adsorption table 2 is provided with X-axis linear motor modules 3 on both sides, a cross beam is arranged on the first sliding block of the two X-axis linear motor modules 3, a Y-axis linear motor module 4 is arranged on the cross beam, a vertical load plate is arranged on the second sliding block of the Y-axis linear motor module 4, a Z-axis linear motor module 5 is arranged on the vertical load plate, a conversion plate is arranged on the third sliding block of the Z-axis linear motor module 5, and a laser module 6 is arranged on the conversion plate. Through the design of three-stage linkage, the laser module 6 can realize accurate and flexible position adjustment in three-dimensional space.

[0036] The laser module 6 comprises a laser and an altimeter. The laser is used to emit a laser beam to cut the material to be cut, and the altimeter is used to measure the distance between the laser module 6 and the material to be cut in real time, and transmit the measurement data to the control system, so that the control system adjusts the Z-axis position of the laser module 6 according to the distance information, ensures that the focal point of the laser beam always accurately falls on the material to be cut, improves the cutting precision and quality, and makes the laser cutting precision deviation reach ±0.005mm.

[0037] The adsorption table 2 in the device is connected with the vacuum system, so that the adsorption table 2 has adsorption capacity. Specifically, the front surface of the adsorption table 2 is designed with a plurality of adsorption holes 21, which are uniformly distributed and can directly act on the material to be cut to produce an adsorption effect. A plurality of pull groove structures 22 are arranged on the back surface of the adsorption table 2, and the pull grooves 22 are connected with each other to form a unified adsorption system. Through the design of the pull grooves 22, each adsorption hole 21 can be connected with the negative pressure source through the pull grooves 22, so as to ensure that each adsorption hole 21 has strong adsorption force.

[0038] In actual application, the adsorption table 2 tightly adsorbs the material to be cut through the adsorption holes 21 on the front surface, effectively preventing the material from shifting or shaking during cutting. The application of the pull grooves 22 further improves the uniformity and stability of adsorption, so that the material to be cut can maintain a fixed position during the entire cutting process, thereby significantly improving the cutting precision and product quality.

[0039] Further, the adsorption holes 21 are arranged in a matrix on the adsorption table 2, which can ensure that the adsorption force uniformly acts on the material to be cut. The spacing between two adjacent adsorption holes 21 is carefully designed to be between 18mm and 24mm, and the preferred spacing is 20mm. Such spacing setting not only ensures the sufficiency of the adsorption effect, but also avoids the mutual interference of the adsorption force caused by too dense adsorption holes 21, and also considers the processing cost and efficiency.

[0040] The pull grooves 22 are composed of transverse pull grooves and longitudinal pull grooves, which are interlaced with each other to form a stable net-like structure. This net-like pull groove structure not only enhances the overall structural strength of the adsorption table 2, but also effectively connects each adsorption hole 21, so that the adsorption force can be uniformly and efficiently transmitted to the material to be cut.

[0041] In this embodiment, the machine table 1 adopts a "concave" structure design with low middle and high sides, which is helpful to effectively collect and process the debris during cutting and prevent it from flying around. The middle position of the machine table 1 is specially used to set the adsorption table 2, and such layout makes the adsorption table 2 fully utilize the "concave" space of the machine table 1, and reserves enough height space for the cutting material.

[0042] The X-axis linear motor module 3 constitutes the movement basis of the entire cutting device in the X-axis direction, which is arranged on the protruding parts of the two sides of the machine table 1. Specifically, the X-axis linear motor module 3 includes a first linear motor extending in the X-axis direction and two first linear guides matched therewith. The two first linear guides are symmetrically distributed on the two sides of the first linear motor, providing stable guiding for the module. The first linear motor itself is composed of a first stator and a first mover, wherein the first mover is fixedly connected with a first slider, and the first slider is slidingly connected with the first linear guide. This connection mode ensures that when the first linear motor operates, the first mover can drive the first slider to slide accurately along the first linear guide, thereby realizing position adjustment in the X-axis direction.

[0043] In the Y-axis direction, the Y-axis linear motor module 4 undertakes the corresponding movement task. The module includes a second linear motor arranged on the cross beam and distributed in the Y-axis direction, and two second linear guides. Similar to the X-axis module, the two second linear guides are respectively located on the upper and lower sides of the second linear motor, providing stable guidance for movement in the Y-axis direction. The second linear motor is composed of a second stator and a second mover, wherein the second mover is fixedly connected with a second slider, and the second slider is slidingly connected with the second linear guide. When the second linear motor starts, the second mover will drive the second slider to slide along the second linear guide, thereby realizing accurate position control in the Y-axis direction.

[0044] As for the Z-axis linear motor module 5, it is responsible for height adjustment in the Z-axis direction. The module includes a third linear motor arranged on the vertical loading plate and distributed in the Z-axis direction. The third linear motor is composed of a third stator and a third mover, wherein the third mover is fixedly connected with a third slider. When the third linear motor operates, the third mover will drive the third slider to move in the Z-axis direction, thereby accurately adjusting the height position of the laser module 6 and ensuring that the laser beam can accurately focus on the material to be cut.

[0045] The utility model fully considers the optimization of material properties and mechanical structure in design, adopts the machine table 1 and adsorption platform 2 of marble material. The marble material has high strength characteristics, can bear various stresses generated in the cutting process, guarantees the long-term stable operation of the device. At the same time, its low thermal expansion coefficient makes the size change of the device very small when the temperature changes, effectively reduces the cutting precision deviation caused by thermal expansion and cold shrinkage. In addition, the good stability of marble also greatly resists the interference of environmental vibration on cutting precision, providing a solid foundation for high-precision cutting.

[0046] In the driving and positioning aspects, the utility model discloses the movement of laser module 6 is carried out with linear motor module, and this design compares traditional screw module, and response speed is fast, and positioning accuracy is high. With the use of laser and altimeter, the focal point position of laser beam can be adjusted in real time, the cutting precision is ensured, and therefore the quality and efficiency of laser cutting are comprehensively improved.

[0047] Meanwhile, the design of the pull groove on the adsorption table is a great innovation, which not only enhances the structural strength of the adsorption table, but also improves the overall adsorption capacity through its unique structure. The pull groove forms a communication between the adsorption holes 21, and the negative pressure distribution is more uniform, thereby more stably adsorbing the material to be cut, and significantly improving the material stability in the cutting process.

[0048] The high-precision laser cutting device is a component of the laser cutting equipment, which is tightly integrated with other parts of the laser cutting equipment, shares the control system, power supply system, gas supply system, vacuum pumping system, etc. of the laser cutting equipment, and realizes the collaborative work of each link through unified interface and operation instructions. The power supply system provides stable power for the device to ensure continuous operation of the equipment; the vacuum pumping system meets the needs of the adsorption table in the device to realize automatic production.
