[0002] Laser cutting replaces traditional mechanical knives with invisible beams of light. It features high precision, fast cutting speed, unlimited cutting patterns, automatic layout saving of materials, smooth cuts, and low processing costs. It will gradually improve or even replace traditional metal cutting equipment. Laser cutting requires the sheet metal to be moved to the laser cutting table.

[0003] After searching, the utility model patent with publication number CN218539163U discloses a material rack lifting device for a laser cutting machine, including a support base column and a storage base column, the bottom end of the support base column is fixedly installed with a support base, the top end of the support base column is fixedly installed with a support arm, the lower surface of the support arm is provided with a support rod, the upper surface of the support arm is fixedly installed with a transverse connecting beam, and the surface of the transverse connecting beam is fixedly installed with two electric push rods; through the above technical scheme, the problem that loading by washing suction cups in the prior art is unstable and easily causes materials to fall is solved, and air is pumped by the vacuum pump so that negative pressure is generated inside the vacuum suction cup to adsorb the surface of the material, thereby realizing the grabbing and fixing of the material, and several connecting ropes are provided on the upper surfaces of the lifting platforms on both sides of the cylinder, and the two ends of the connecting ropes are fixedly connected to the cylinder and the lifting platform respectively, and the transmission base can move parallel to the two directions of the guide slide groove during the rotation of the transmission bolt.

[0026] See also Figure 1-4 A material rack lifting device for a laser cutting machine includes two supporting bases 1, the top surfaces of the two supporting bases 1 are fixedly connected with supporting columns 2, the tops of the two supporting columns 2 are provided with moving mechanisms 3, a main lifting box 4 is provided on the moving mechanism 3, both sides of the main lifting box 4 are fixedly connected with supporting plates 5, the top surfaces of the two support plates 5 are fixedly connected with two mounting seats 6, three electric push rods 7 are fixedly installed on the four mounting seats 6, the output ends of the four third electric push rods 7 are fixedly connected with two auxiliary lifting boxes 8, the outer sides of the two auxiliary lifting boxes 8 are respectively provided with supporting mechanisms 9, and two suction mechanisms 10 are respectively provided on the main lifting box 4 and the auxiliary lifting box 8.

[0027] For details, please refer to Figure 1 and Figure 3 The support mechanism 9 includes an L-shaped bracket 11 fixedly connected to the outside of the auxiliary lifting box 8, and a plurality of fifth electric push rods 12 are fixedly mounted on the L-shaped bracket 11. The output ends of the plurality of fifth electric push rods 12 are fixedly connected to a support seat 13.

[0028] In this embodiment, the fifth electric push rod 12 is used to drive the support seat 13 to move horizontally. When multiple suction cups 18 adsorb the material and move upward, the support seat 13 moves to the bottom of the material, thereby using the support seat 13 to support the material and ensure the firmness of the material grasping.

[0029] For details, please refer to Figure 1 and Figure 4 The suction mechanism 10 includes a fourth electric push rod 14 fixedly mounted on the top surface of the main lifting box 4 or the auxiliary lifting box 8. The output end of the fourth electric push rod 14 is fixedly connected to the installation box 15. An exhaust hole 16 is provided on the side of the installation box 15. An air pump 17 is fixedly installed in the inner cavity of the installation box 15. The input end of the air pump 17 extends to the bottom of the installation box 15 and is fixedly sleeved with a suction cup 18.

[0030] In this embodiment, the outer size of the installation box 15 is smaller than the inner size of the main lifting box 4 and the auxiliary lifting box 8, ensuring that the installation box 15 can be retracted into the inner cavities of the main lifting box 4 and the auxiliary lifting box 8.

[0031] For details, please refer to Figures 1 to 3 The moving mechanism 3 includes a support frame 19 fixedly connected to the top of the two supporting base columns 2, and a crossbeam 20 is fixedly connected to one side of the top surface of the support frame 19. A plurality of first electric push rods 21 are fixedly installed on the crossbeam 20, and the output ends of the plurality of first electric push rods 21 are fixedly connected to the transverse box 22.

[0034] For details, please refer to Figure 2 The inner wall of the transverse shift box 22 and the top and bottom surfaces of the transverse shift seat 24 are in contact with each other.

[0035] In this embodiment, the inner wall of the transverse shift box 22 is used to limit the transverse shift seat 24 so that the transverse shift seat 24 can only move along the axial direction of the screw rod 23.

[0036] Working principle: When in use, first move the device to the side of the laser cutting machine, start the servo motor 26 to drive the screw 23 to rotate, and through the threaded fit between the screw 23 and the transverse seat 24, drive the main lifting box 4 and the auxiliary lifting box 8 to move to the top of the material to be loaded. At this time, start the third electric push rod 7 to drive the two auxiliary lifting boxes 8 to move, so that the two auxiliary lifting boxes 8 move to just above the two ends of the top surface of the material, and then start the fourth electric push rod 14 to drive multiple installation boxes 15 and multiple suction cups 18 to move downward, start the vacuum pump 17 to extract air from the inner cavity of the suction cup 18, and use the negative pressure in the inner cavity of the suction cup 18 to adsorb the material. At this time, start the fourth electric push rod 14 to drive the installation box 15. The suction cup 18 and the material move upward, so that the material moves to the inner side of the two L-shaped brackets 11, and then the fifth electric push rod 12 is started to drive the support seat 13 to move, so that the support seat 13 moves to the lower part of the two ends of the material, and the support seat 13 is used to lift and support the material. Finally, the second electric push rod 25 is used to drive the main lifting box 4, the auxiliary lifting box 8 and the material to move upward as a whole, and the threaded combination of the screw rod 23 and the transverse seat 24 is used to drive the material to move horizontally. The first electric push rod 21 is used to drive the transverse box 22 and the material to move back and forth, so as to move the material to the top of the cutting table of the laser cutting machine, and place the material on the laser cutting machine according to the reverse steps of grabbing the material.
