[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf (e.g., 0.1 mm), thus completing the cutting of the material.

[0003] Chinese Patent No. CN219113192U discloses a three-dimensional laser cutting device, including an operating table. A slider is mounted on top of the operating table, and a laser head is fixedly connected to the bottom of the slider. A protective sleeve is fitted around the laser head and fixedly connected to the bottom of the slider. A coil is fitted around the laser head and fixedly connected to the inner ring of the protective sleeve. The air outlet of the coil is connected to a dust removal component. An air intake and purification component that works with the coil is mounted on the operating table. The air intake and purification component includes a ring pipe, an air inlet, a third air duct, a spray box, a connecting pipe, a drying box, and an exhaust fan. This three-dimensional laser cutting device, equipped with a coil, a dust removal component, and an air intake and purification component, cools the laser head while simultaneously removing dust, irritating gases, and solid debris generated during cutting, thereby improving cutting efficiency.

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] Example 1

[0027] like Figure 1 - Figure 5 As shown, the present invention proposes a three-dimensional laser cutting device, comprising: a cutting table 1, a laser eye protection barrier 2, a clamping assembly 3, a dust collection assembly 4, a laser head 5, and a robotic arm 6; the cutting table 1 is provided with a cooling chamber 101, which is connected to a cooling component; the cooling component includes a semiconductor cooling chip 102, which is connected to a mounting plate 103 and a cable 104, and the mounting plate 103 is connected to mounting blocks 105 at both ends, which are connected to both sides of the cutting table 1; the cutting table 1 is connected to the laser eye protection barrier 2; the laser head 5 is movably connected above the cutting table 1, and the laser head 5 is connected to the robotic arm 6; the clamping assembly 3 is connected to the cutting table 1; and the dust collection assembly 4 is connected to the cutting table 1. Sheet metal materials from the hand dryer production line to be laser-cut are placed on the cutting table 1. The clamping component 3 clamps the workpiece, and the laser head 5 moves through the robotic arm 6 to cut the workpiece. During the laser cutting process, a hot zone is generated, which is cooled by the cooling component of the cutting table 1 to avoid damage to the material properties of the workpiece, improve the practicality of the three-dimensional laser cutting equipment, and conveniently improve the cutting efficiency of sheet metal materials in the hand dryer production line.

[0028] To further explain, cable 104 passes through mounting plate 103 and is electrically connected to power supply equipment. Mounting plate 103 is provided with through holes. Mounting block 105 is detachably connected to both sides of cutting table 1. Power supply equipment connects to semiconductor cooling chip 102. Utilizing the Peltier effect of semiconductor materials, when direct current passes through a coupler formed by two different semiconductor materials connected in series, heat can be absorbed and released at the two ends of the coupler respectively, achieving the purpose of cooling. Semiconductor cooling chip 102 has high reliability and enhances the functionality of the three-dimensional laser cutting equipment.

[0029] To further explain, a base 106 is connected below the cutting table 1, and a clamping seat 107 is connected to the base 106. The base 106 and the clamping seat 107 together form an installation area for connecting the laser eye protection barrier 2. When the 3D laser cutting equipment is in use, the laser eye protection barrier 2 plays a protective role, preventing accidental injury to workers and improving the applicability of the 3D laser cutting equipment.

[0030] To further explain, the clamping assembly 3 has two components, each including a mounting bracket 301 connected to the cutting table 1. The mounting bracket 301 is connected to a cylinder 302, and the drive end of the cylinder 302 is connected to a clamping plate 303, which is connected to the cutting table 1. The mounting bracket 301 is also connected to a guide component. Sheet metal workpieces from the hand-operated production line are placed on the cutting table 1 for cutting. First, the two clamping assemblies 3 clamp the workpieces on both sides, conveniently increasing cutting accuracy and ensuring the workpieces are placed stably on the cutting table 1.

[0031] Further explanation: The guide component includes a support plate 304, a fixing rod 305, and a connecting rod 306 connected to the mounting bracket 301. The fixing rod 305 is hollow inside, with an opening at one end. One end of the connecting rod 306 passes through the support plate 304 and connects to the opening, while the other end of the connecting rod 306 is connected to the clamping plate 303. The connecting rod 306 and the fixing rod 305 together form a telescopic mechanism. During the adjustment of the clamping plate 303's operating range, the connecting rod 306 moves synchronously, conveniently increasing the stability of the clamping plate 303's movement and enhancing the usability of the clamping assembly 3.

[0032] Example 2

[0033] like Figure 2 As shown, the present invention proposes a three-dimensional laser cutting device. Based on the above embodiments, this embodiment also details the specific components of the dust collection component 4 and its assembly method.

[0034] Further explanation: The dust collection component 4 includes a frame 401 connected to the cutting table 1. A suction pipe 402 is connected to the inner wall of the frame 401. The suction pipe 402 passes through the frame 401 and connects to a connecting pipe 403, which in turn connects to a dust collection device 404. The connecting pipe 403 connects to a support frame 405, which is mounted on the cutting table 1. The dust collection device 404, in existing publicly available technology, allows sheet metal workpieces in a hand-operated production line to be placed on the cutting table 1 for cutting. When the dust collection device 404 is turned on, it connects to the connecting pipe 403 and the suction pipe 402, with the suction pipe 402 having an intake port, to effectively remove and treat the fumes or debris generated during the cutting process, thus improving the efficiency of the 3D laser cutting equipment.

[0035] The working principle of this utility model is as follows: First, the sheet metal workpiece to be cut in the hand-operated production line is placed on the cutting table 1. The cylinder 302 is started, and the piston rod at the driving end of the cylinder 302 causes the clamping plate 303 to move on the cutting table 1, moving to both sides of the workpiece to limit its position. The cable 104 passes through the mounting plate 103 and is electrically connected to the power supply equipment, so that the semiconductor cooling chip 102 absorbs heat in the cooling chamber 101 and releases heat through the through hole, thereby cooling the cutting table 1 and facilitating the cutting of the sheet metal workpiece in the hand-operated production line on the cutting table 1. Then, the two ends of the mounting plate 103 are connected to the mounting block 105, and the mounting block 105 is connected to both sides of the cutting table 1 by bolts. By controlling the bolts, it is easy to remove the semiconductor cooling chip 102 from the cooling chamber 101, so that the cooling component can be installed to cooperate with the cutting table 1 as needed, which facilitates the operation of the three-dimensional laser cutting equipment.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
