Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting processing, and in particular relates to an adsorption-fixed laser cutting device for metal plates. Background Art

[0002] A laser cutting machine uses a laser beam emitted from a laser generator, focused through an optical system into a high-power, high-density laser beam. The laser beam strikes 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. As the beam and workpiece move relative to each other, a slit is formed in the material, achieving the desired cutting effect.

[0003] After the thicker metal plate is cut into small parts, an external robot removes the processed small parts for subsequent processing. Due to the cutting of the metal plate, its center of gravity will change. When using a suction cup for adsorption and fixation, the suction cup itself is made of soft material. The metal plate with a changed center of gravity exerts different pressures on the suction cups at different positions, causing the metal plate to move, thereby affecting the processing of the metal plate. Utility Model Content

[0004] The utility model addresses the problem in the prior art that a metal plate, whose center of gravity changes during processing, exerts different pressures on suction cups at different positions, causing the position of the metal plate to move and affecting the processing of the metal plate. The utility model proposes the following technical solutions:

[0005] A metal sheet adsorption fixed laser cutting device includes: a loading platform and an adsorption component, a holding groove is provided on the top of the loading platform, and the loading platform drives the internal workpiece to be processed through the holding groove to be cut through the laser cutting mechanism, and the adsorption component includes a plurality of hollow connecting rods, and the hollow connecting rods are connected to the external exhaust equipment through pipes, and the top of the hollow connecting rod is located at the non-processing position of the product and a plurality of suction cups are provided at the bottom, and a tensioning plate is fixedly connected to the side of the suction cup, and an electromagnet is provided at the bottom of the tensioning plate.

[0006] After the suction cup is adsorbed on the surface of the workpiece to be processed, the magnetic force generated by the power supply of the electromagnet will adsorb the tensioning plate and pull the suction cup down, so that the workpiece to be processed will contact the surface of the holding tank. The suction cup can adsorb and fix the workpiece to be processed, and will not be squeezed and deformed by the workpiece to be processed because it is made of soft material, thereby avoiding the movement of the workpiece to be processed due to the change of its center of gravity due to processing, which will affect its processing.

[0007] As a preferred embodiment of the above technical solution, an elastic ring is provided between the tensioning piece and the electromagnet, and the middle portion of the elastic ring is hollow.

[0008] The elastic ring can support the suction cup through the tensioning sheet to prevent the suction cup from being directly squeezed to the surface of the holding tank when the workpiece is placed, thereby ensuring that the suction cup can normally adsorb and fix the workpiece when vacuuming.

[0009] As a preferred embodiment of the above technical solution, a hose is provided between the bottom of the suction cup and the hollow connecting rod, and the hose is provided in a folded shape.

[0010] The folded hose can meet the needs of the suction cup's movement while ensuring a sealed connection between the suction cup and the hollow connecting rod, so that the suction cup can perform adsorption and fixing work normally.

[0011] As a preferred embodiment of the above technical solution, it also includes a base plate, the top of the base plate is fixedly connected to the loading platform, and the bottom of the base plate is connected to the external guide rail slider.

[0012] The base plate is used to facilitate the installation of the loading platform, and different sizes of workpieces can be processed by replacing different loading platforms.

[0013] The beneficial effects of the utility model are:

[0014] 1. After the suction cup is adsorbed on the surface of the workpiece, the magnetic force generated by the electromagnet when it is energized will adsorb the tensioning sheet and pull the suction cup down, so that the workpiece will contact the surface of the holding tank. The suction cup can adsorb and fix the workpiece while not being squeezed and deformed by the workpiece because it is made of soft material, thereby preventing the workpiece from moving due to the change of its center of gravity during processing and affecting its processing.

[0015] 2. The elastic ring can support the suction cup through the tensioning sheet to prevent the suction cup from being squeezed directly to the surface of the holding tank when the workpiece is placed, thereby ensuring that the suction cup can normally adsorb and fix the workpiece when vacuuming.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0022] Example

[0023] Figures 1-4 In the invention, a metal sheet adsorption fixed laser cutting device includes: a loading platform 10 and an adsorption component 20, a holding groove 11 is opened on the top of the loading platform 10, and the loading platform 10 drives the internal workpiece 40 to be processed to be cut through the laser cutting mechanism through the holding groove 11, and the adsorption component 20 includes a plurality of hollow connecting rods 21, and the hollow connecting rods 21 are connected to the external exhaust equipment through a pipe. The top of the hollow connecting rod 21 is located at the non-processing position of the product and a plurality of suction cups 22 are provided at the bottom. The top of the suction cup 22 is higher than the bottom surface of the holding groove 11, and the side of the suction cup 22 is fixedly connected with a tensioning plate 23, and the tensioning plate 23 is made of iron, and an electromagnet 24 is provided at the bottom of the tensioning plate 23.

[0024] After the suction cup 22 is adsorbed on the surface of the workpiece 40, the magnetic force generated by the electromagnet 24 being energized will adsorb the tensioning plate 23 so that it pulls the suction cup 22 down, and then the workpiece 40 to be processed is brought into contact with the surface of the holding tank 11. The suction cup 22 can adsorb and fix the workpiece 40 to be processed, and will not be squeezed and deformed by the workpiece 40 because it is made of soft material, thereby avoiding the workpiece 40 to be processed 40 whose center of gravity is changed due to processing and affecting its processing.

[0025] Figure 3-Figure 4 In the embodiment, an elastic ring 25 is provided between the tensioning piece 23 and the electromagnet 24, and the middle portion of the elastic ring 25 is hollow.

[0026] The elastic ring 25 can support the suction cup 22 through the tensioning sheet 23 to prevent the suction cup 22 from being directly squeezed to the surface of the holding tank 11 when the workpiece 40 is placed, thereby ensuring that the suction cup 22 can normally adsorb and fix the workpiece 40 when vacuuming.

[0027] Figure 3-Figure 4 In the embodiment, a hose 26 is provided between the bottom of the suction cup 22 and the hollow connecting rod 21, and the hose 26 is provided in a folded shape.

[0028] The folded hose 26 can satisfy the movement of the suction cup 22 while ensuring the sealed connection between the suction cup 22 and the hollow connecting rod 21, so that the suction cup 22 can perform the adsorption and fixing work normally.

[0029] Figure 1-Figure 2 The machine also includes a bottom plate 30, the top of the bottom plate 30 is fixedly connected to the loading platform 10, and the bottom of the bottom plate 30 is connected to the external guide rail slider.

[0030] The base plate 30 is used to facilitate installation of the loading platform 10 , and different sizes of workpieces can be processed by replacing different loading platforms 10 .

[0031] Working principle: When cutting the workpiece 40, the workpiece 40 is first placed in the holding groove 11 of the loading platform 10, and the bottom surface of the workpiece 40 contacts the surfaces of multiple suction cups 22. At this time, the suction cup 22 and the tensioning piece 23 partially move down and compress and deform the elastic ring 25. Then, the external exhaust equipment vacuums the inside of the suction cup 22 through the pipeline, and the suction cup 22 is then adsorbed on the surface of the workpiece 40 to limit the horizontal position of the metal plate. Then, the electromagnet 24 is started to energize it, and the tensioning piece 23 is magnetically adsorbed to move the suction cup 22 downward and make its end flush with the surface of the holding groove 11. While the elastic ring 25 continues to be compressed and deformed, the folded hose 26 is also compressed and deformed to meet the movement of the suction cup 22. Due to the downward pulling effect of the tensioning piece 23 on the suction cup 22, the bottom surface of the workpiece 40 is in contact with the surface of the holding groove 11, thereby fixing the workpiece 40 to prevent the workpiece 40 from moving due to the change of its center of gravity during processing and affecting the processing of the workpiece 40.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
