Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a smart laser cutting platform. Background Technology

[0002] Laser cutting machines use a laser beam emitted from a laser source, which is then focused into a high-power-density laser beam through an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Laser cutting machines are widely used in metal processing, but the cutting process generates a large amount of waste slag and exhaust gas. Especially when cutting certain metal materials, a large amount of molten slag accumulates on the cutting platform. Cleaning requires operators to use a handheld air gun, making subsequent slag collection and disposal extremely inconvenient. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide a smart laser cutting platform to address the above-mentioned problems.

[0004] A laser cutting intelligent platform includes a carrier plate, a slag collection device, and a vacuum adsorption head. The slag collection device is installed below the carrier plate and includes a hopper and a negative pressure fan. The negative pressure fan is installed below the slag head and communicates with the hopper. Several slag grooves are arranged side by side at intervals on the carrier plate. Both ends of the slag grooves are connected to the slag head. A support part is provided between two slag grooves. The vacuum adsorption head is installed in the support part for adsorbing the workpiece to be cut. A liquid cooling pipe is also embedded in the support part.

[0005] Preferably, a roller is movably disposed on the support portion, and the roller is disposed along the extension direction of the support portion.

[0006] Preferably, the rollers are elastically disposed on the support, and the vacuum suction head is installed between two rollers arranged in a straight line.

[0007] Preferably, the hopper is equipped with a filter screen.

[0008] The advantages of this invention are: under the dual action of air blowing from the laser cutting head and negative pressure suction from the negative pressure fan, the welding slag falls directly into the hopper along the welding slag groove, completing the welding slag collection work. There is no need to clean the carrier plate after laser cutting, which reduces the labor intensity of workers and improves production efficiency. Attached Figure Description

[0011] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] like Figures 1-2As shown, a laser cutting intelligent platform is characterized by comprising a carrier plate 1, a slag collection device 2, and a vacuum adsorption head 3. The slag collection device 2 is installed below the carrier plate 1 and includes a hopper 21 and a negative pressure fan 22. The negative pressure fan 22 is installed below the head 21 and communicates with the hopper 21. Several slag grooves 11 are arranged side by side at intervals on the carrier plate 1. Both ends of the slag grooves 11 are communicated with the head 21. A support part 12 is provided between two slag grooves 11. The vacuum adsorption head 3 is installed in the support part 12 for adsorbing the workpiece to be cut. A liquid cooling pipe 4 is also embedded in the support part 12. Specifically, the carrier plate 1 is used to support the workpiece to be processed. A slag groove 11 and a support part 12 are provided on the carrier plate 1. The support part 12 is used to support the workpiece. During the laser cutting process, slag will inevitably fall. Because the existing laser cutting head integrates an air gun, the air outlet direction of the air gun is consistent with the high-energy laser beam and coaxial with the high-energy laser beam. The high-pressure gas, such as nitrogen, can not only suppress the oxidation reaction during workpiece cutting, but also carry away the heat of the molten metal. It can also blow away the slag generated by laser cutting on the surface of the workpiece. The slag will eventually collect in the slag groove 11. Because the two ends of the slag groove 11 are connected to the hopper 21, under the dual action of the air blowing of the laser cutting head and the negative pressure suction of the negative pressure fan 22, the slag falls directly into the hopper 21 along the slag groove 11, completing the slag collection work. There is no need to clean the carrier plate 1 after the laser cutting is completed, which reduces the labor intensity of workers and improves production efficiency. In this design, a support part 12 is set between the two welding slag grooves 11 to support the workpiece. A vacuum adsorption head 3 is pre-embedded in the support part 12 to adsorb the flat workpiece and prevent the workpiece from slipping during processing. The function of the liquid cooling pipe 4 is to provide heat dissipation for the workpiece through the support part 12 when the workpiece is laser cut into thin plate-shaped metal workpieces, so that the workpiece may warp in some areas and the liquid cooling pipe 4 can prevent the workpiece from warping due to overheating.

[0015] like Figures 1-2 As shown, a roller 13 is movably disposed on the support portion 12, and the roller 13 is arranged along the extending direction of the support portion 12. Specifically, both ends of the roller 13 are movably connected to the support portion 12 via bearings, and the circumferential surface of the roller 13 is slightly higher than the end face of the support portion 12, specifically 0.5 to 2 mm. In actual testing, this does not affect the vacuum adsorption head's ability to adsorb and grip the workpiece. When the workpiece to be processed moves on the support portion 12, it is in contact with the roller 13, resulting in rolling friction and reducing the frictional resistance when the workpiece is adjusted on the support portion 12.

[0016] Specifically, the roller 13 is elastically mounted on the support portion 12, achieved through a spring. When the workpiece on the roller 13 is adsorbed by the vacuum suction head 3, the roller 13 is compressed, and the spring supporting the roller 13 protruding from the end face of the support portion 12 is compressed, making the circumferential surface of the roller 13 flush with the end face of the support portion 12. At this time, the workpiece is firmly adsorbed on the support portion 12 and will not slip. When it is necessary to adjust the position of the workpiece, the vacuum suction head 3 stops working, the roller 13 is no longer compressed, the spring returns to its original position, and the roller 13 rises again, protruding from the support portion 12, allowing the user to slide the workpiece on the roller 13. The vacuum suction head 3 is installed between two rollers 13 arranged in a straight line, so the presence of the rollers 13 will not affect the internal air passage layout.

[0017] Specifically, a filter screen is installed inside the hopper 21 as the first line of defense. It uses mechanical blocking to intercept large particles such as metal shavings and condensed dust generated by laser cutting, preventing them from entering the subsequent purification system and causing blockages or equipment wear.

[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
