[0026] The utility model realizes the automatic grabbing, conveying and positioning of plate material, without manual intervention, greatly improve the automation production level of laser cutting machine, simultaneously through the automatic feeding process, reduce the physical labor intensity of operator, improve the working environment, in addition, can quickly, accurately convey plate material to the laser cutting machine workstation, improve production efficiency.

[0027] In the embodiment, rack plate 18 is fixed on the outer side of support arm 14, reduction motor 17 is installed on the outer side of track arm 1, drive gear 19 is assembled on the output end of reduction motor 17, and drive gear 19 is in meshing transmission connection with rack plate 18.When reduction motor 17 is started, drive gear 19 starts to rotate, and since drive gear 19 is in meshing transmission connection with rack plate 18, rack plate 18 will move with the rotation of drive gear 19, and the movement of rack plate 18 drives the sliding of support arm 14 in track arm 1, so as to realize the adjustment of the position of support arm 14.Through the transmission of reduction motor 17 and drive gear 19, the movement speed and position of support arm 14 can be accurately controlled, and then the workpiece is moved to the upper side of the laser cutting machine, so as to meet the requirement of the laser cutting machine on the accuracy of feeding position.

[0028] In this embodiment, the top of the two groups of track arms 1 is fixedly connected through the two groups of cross beam plates 8, the front cross beam plate 8 is provided with an electric winch 9, the rear cross beam plate 8 is fixedly provided with an n-shaped fixing frame 5, the inside top of the fixing frame 5 is provided with a pulley 6, the electric winch 9 is wound with a suspension steel cable 7, and the end of the suspension steel cable 7 is fixedly connected to the rear connecting plate 4 through the pulley 6. The design further enhances the stability of the support arm 14 through the tensioning effect of the suspension steel cable 7. When the support arm 14 moves, the electric winch 9 is started, and the support demand for the position of the support arm 14 can be met by winding and unwinding the suspension steel cable 7. Through the design of the cross beam plate 8, the fixing frame 5 and the suspension steel cable 7, the stability of the support arm 14 when moving is enhanced, and it is ensured that the support arm 14 will not tilt and deviate during movement.

[0029] In this embodiment, the inside of the sliding frame 15 is provided with a roller driven by a motor, and the roller is connected with the sliding rail 16. The design can drive the sliding frame 15 to move on the sliding rail 16 through the motor driving the roller, thereby driving the workpiece plate to move horizontally on the support arm 14, and realizing the adjustment of the position of the workpiece plate.

[0030] In this embodiment, the bottom of the support arm 14 is fixedly provided with a limiting sliding block 21 near the front end, the bottom of the track arm 1 is provided with a sliding groove 20 matched with the limiting sliding block 21, and the limiting sliding block 21 is clamped into the sliding groove 20 and connected with the sliding groove 20.

[0031] The working principle of the automatic feeding device of the laser cutting machine is as follows:

[0032] Before the device starts, the workpiece plate is stored on the base plate 2, the supporting arm 14 is completely located inside the track arm 1, and the cross bar 10 is located at the center position of the device. At this time, the lifting electromagnet 12 is in an inactive state, waiting to grab the workpiece. When feeding is needed, the hoist 11 starts, and the lifting steel cable 13 lowers the lifting electromagnet 12 to the workpiece stacking area. Two groups of lifting electromagnets 12 are activated and respectively adsorb the symmetrical positions on the workpiece plate to be cut. Then the hoist 11 starts again, and the lifting steel cable 13 lifts the lifting electromagnet 12 and the adsorbed workpiece plate upward. The speed reducer motor 17 starts, and through the meshing transmission of the driving gear 19 and the rack plate 18, the supporting arm 14 is driven to move outward, so that the supporting arm 14 moves above the workbench of the cutting machine. During the movement of the supporting arm 14, the electric winch 9 retracts and releases the suspension steel cable 7 according to the position of the supporting arm 14, and through the cooperation of the pulley 6 and the fixed frame 5, the stability of the supporting arm 14 is enhanced. Then the motor-driven roller in the sliding carriage 15 moves the sliding carriage 15 along the slide rail 16, so as to drive the workpiece plate to adjust the horizontal position on the supporting arm 14. By accurately controlling the movement of the sliding carriage 15, the workpiece plate is adjusted to be directly above the workbench of the laser cutting machine. When the workpiece plate reaches the specified position of the workbench of the laser cutting machine, the hoist 11 controls the lifting electromagnet 12 to descend, and the workpiece plate is placed on the workbench. The lifting electromagnet 12 loses power and releases the workpiece plate. After completing the feeding once, the device returns to the initial position and is ready for the next feeding operation.

[0033] In summary, the automatic feeding device of the laser cutting machine realizes automatic grabbing, conveying and positioning of the plate, without manual intervention, greatly improves the automatic production level of the laser cutting machine, reduces the physical labor intensity of the operator, and improves the production efficiency.

[0034] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description, and all the embodiments cannot be exhausted here. Any obvious changes or variations derived from the technical solutions of the utility model still fall within the protection scope of the utility model.
