Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a large-scale feeding laser cutting production line. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize, ablate or reach the ignition point quickly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. It has the characteristics of high precision, fast cutting and good effect.

[0003] The existing laser cutting machine is only a single device. For example, in the patent document with application number CN202320361886.7 and titled "A laser cutting machine for fence production", the motor rotates one of the lead screws, and the lead screw moves the horizontal moving frame, and the direction of the motor rotation controls the left and right movement, and the other motor rotates another lead screw, and the lead screw moves the vertical moving frame, and the direction of the motor rotation controls the forward and backward movement, and the motor rotates the lead screw, and the lead screw moves the laser cutting machine, and the direction of the motor rotation controls the up and down movement of the laser cutting machine.

[0004] As described in the patent document with application number CN202210461961.7 and titled "A laser cutting machine with self-cleaning function", when in use, the position of the laser cutting head is adjusted according to the thickness of the substrate, and the third motor rotates. The rotation of the third motor drives the third screw to rotate, and the third screw thread drives the sleeve and the slide frame to slide. At the same time, the second hydraulic cylinder is extended to drive the mounting sleeve to slide to the bottom end of the sleeve. At this time, the laser cutting head is in a suitable cutting position, and then the belt is driven by the pulley on the second motor to rotate the pulley on the second screw, and the second screw thread drives the gantry and the laser cutting machine body to slide. The first motor drives the first screw, so that the first screw thread drives the slider to slide, and then the position of the laser cutting head is adjusted to cut the substrate into multiple workpieces.

[0005] The laser cutting machines disclosed in the above two patents require manual transportation of sheet materials to the laser cutting machines before use, which not only has low work efficiency but also has a low safety factor. Utility Model Content

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0033] Reference Figure 1 As shown, a large-scale feeding laser cutting production line includes a base 34, on which a feeder 1, a leveler 3, a position limiting mechanism, a material pulling mechanism 8, a cutting mechanism and a finished product conveying mechanism are sequentially fixed. The material 2 wound from the feeder 1 passes through the leveler 3, the position limiting mechanism, the material pulling mechanism 8 and the cutting mechanism in sequence.

[0034] Reference Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the material pulling mechanism 8 includes a support 16, two parallel racks 18 are fixed on the upper end of the support 16, and an inverted U-shaped cover 9 is slidably arranged on the upper end of the support 16. Specifically, a slide groove 19 is opened on the upper end of the support 16, and the length direction of the slide groove 19 is parallel to the length direction of the rack 18, and the lower end of the cover 9 is slidably arranged in the slide groove 19.

[0035] A connecting shaft 27 is rotatably connected in the cover 9, and a gear 26 meshing with the rack 18 is fixed on the connecting shaft 27. A motor 20 is fixed on one side of the cover 9, and the output shaft of the motor 20 is fixedly connected to the connecting shaft 27. The motor 20 is electrically connected to the controller.

[0036] Reference Figure 6 and Figure 7As shown, a spring pin 30 is fixed inside the output shaft of the motor 20, and the axis of the spring pin 30 is perpendicular to the axis of the motor 20. The output shaft of the motor 20 passes through the inner hole of the cam 24, and the movable end of the spring pin 30 is clamped in the arc groove on the wall of the inner hole of the cam 24. A first stopper 25 and a second stopper 28 are fixed inside the cover body 9, and the cam 24 is located between the first stopper 25 and the second stopper 28.

[0037] A clamping assembly is slidably connected in the vertical direction inside the cover body 9 , and the material 2 wound off the unwinding machine 1 passes between the clamping assembly and the top plate of the cover body 9 .

[0038] The cam 24 rotating with the output shaft of the motor 20 can lift the clamping assembly and cooperate with the top plate of the cover body 9 to clamp the material 2. When the clamping assembly cooperates with the top plate of the cover body 9 to clamp the material 2, the cam 24 is blocked by the second stop rod 28.

[0039] The clamping assembly includes a connecting plate 23, which is slidably disposed in a vertical groove 29 on the inner side of the cover body 9. A plurality of first springs 22 are fixed to the upper end of the connecting plate 23. The pressing plate 21 is located in the cover body 9, and the upper ends of the plurality of first springs 22 are fixedly connected to the pressing plate 21. Vertical light rods 35 are fixed to the four corners of the upper end of the pressing plate 21, and the light rods 35 penetrate the top plate of the cover body 9, and the light rods 35 are slidably connected to the top plate of the cover body 9. The material 2 penetrates between the top plate of the cover body 9 and the pressing plate 21.

[0040] Reference Figure 2 As shown, the limiting mechanism includes a third bracket 17, a U-shaped first housing 7 is fixed on the upper end of the third bracket 17, and two rollers 4 are rotatably connected in the first housing 7. Two first electric telescopic rods 5 are fixed in the housing between the two rollers 4, and the two first electric telescopic rods 5 are arranged opposite to each other. Positioning plates 6 are fixed on the telescopic ends of the two first electric telescopic rods 5. The rollers 4 support the material 2. The material 2 runs through the two positioning plates 6.

[0041] The cutting mechanism comprises a workbench 11 on which a laser cutting machine 10 is mounted.

[0042] Reference Fig. 9 and Fig.10 As shown, the finished product conveying mechanism includes a second bracket 14 fixedly connected to the workbench 11. A conveyor belt 12 is installed on the second bracket 14. Slideways 36 are provided on the second brackets 14 on both sides of the conveyor belt 12, and the length direction of the slideways 36 is perpendicular to the conveying direction of the conveyor belt 12. A sliding block 33 is slidably arranged in the slideway 36. The upper end of the sliding block 33 is rotatably connected to the limit wheel 13, and the sliding block 33 is connected to the second bracket 14 through a telescopic component.

[0043] Specifically, the telescopic component is a second electric telescopic rod 32 . One end of the second electric telescopic rod 32 is fixedly connected to the second bracket 14 , and the other end of the second electric telescopic rod 32 is fixedly connected to the sliding block 33 .

[0044] After the material 2 is wound out from the unwinding machine 1, it passes through the leveling machine 3, and the leveling machine 3 can level the material 2. The leveled material 2 passes between the two positioning plates 6, and the rollers 4 can support the material 2. The two positioning plates 6 can limit the material 2 to ensure that the material 2 enters the cutting mechanism according to the preset position. The material 2 passing between the two positioning plates 6 passes through the top plate of the cover body 9 and the pressure plate 21.

[0045] By starting the two first electric telescopic rods 5 , the distance between the two positioning plates 6 can be adjusted, so as to facilitate the positioning of materials 2 with different widths.

[0046] Reference Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, when the material 2 is conveyed toward the cutting mechanism by the material pulling mechanism 8, the motor 20 is started, so that the output shaft of the motor 20 drives the connecting shaft 27, the gear 26 and the cam 24 to rotate toward the first stop rod 25. During the rotation of the cam 24 toward the first stop rod 25, the pressing plate 21, the first spring 22 and the connecting plate 23 move downward under the action of gravity. When the cam 24 is blocked by the first stop rod 25, as the motor 20 continues to rotate, the movable end of the spring pin 30 withdraws from the arc groove of the cam 24, and the output shaft of the motor 20 and the cam 24 rotate relative to each other. Under the cooperation of the gear 26 and the rack 18, the cover body 9 moves toward the right side. In this process, the pressing plate 21 and the top plate of the cover body 9 do not clamp the material 2.

[0047] When the cover body 9 moves to the right end of the support 16, the motor 20 is started, so that the output shaft of the motor 20 drives the connecting shaft 27, the gear 26 and the cam 24 to rotate in the direction of the second gear rod 28. During the movement of the cam 24 in the direction of the second gear rod 28, the cam 24 can drive the connecting plate 23, the first spring 22 and the pressing plate 21 upward. When the cam 24 is contacted by the second gear rod 28, the pressing plate 21 and the top plate of the cover body 9 clamp the material 2. As the motor 20 continues to rotate, the movable end of the spring pin 30 withdraws from the arc groove of the cam 24, and the output shaft of the motor 20 and the cam 24 rotate relative to each other. Under the cooperation of the gear 26 and the rack 18, the cover body 9 moves to the left. In this process, the pressing plate 21 and the top plate of the cover body 9 clamp the material 2 and drive the material 2 to move to the left.

[0048] By providing the first spring 22 , the pressing plate 21 and the top plate of the cover body 9 can clamp the materials 2 of different thicknesses.

[0049] After the material 2 is located on the workbench 11, the laser cutting machine 10 is started to cut the material 2. The trolley 15 is pushed to the left side of the conveyor belt 12. After the cut finished product is pushed onto the conveyor belt 12, the conveyor belt 12 can transport the finished product to the trolley 15. During the process of the conveyor belt 12 transporting the finished product, the two second electric telescopic rods 32 can be started according to the width of the finished product to adjust the spacing between the two limiting wheels 13. During the process of the conveyor belt 12 transporting the finished product, the two limiting wheels 13 can adjust the position of the finished product, and the finished product can be neatly stacked on the trolley 15 after leaving the conveyor belt 12. By setting the second electric telescopic rod 32, the limiting wheels 13 can adjust the position of finished products of different widths during the process of being transported by the conveyor belt 12.

[0050] When the material 2 on the workbench 11 is cut and needs to be moved further onto the workbench 11, the motor 20 is started so that the output shaft of the motor 20 drives the connecting shaft 27 and the gear 26 to rotate toward the first stop bar 25. The cover body 9 moves to the right. At this time, the pressing plate 21 and the top plate of the cover body 9 keep clamping the material 2. The cam 24 rotates relative to the output shaft of the motor 20. During the relative rotation of the cam 24 and the output shaft of the motor 20, the material 2 is pulled to the right for a distance. When the movable end of the spring pin 30 enters the arc groove of the cam 24 again, the cam 24 will follow the output shaft of the motor 20 to move toward the first stop bar 25. During the rotation of the cam 24 toward the first stop bar 25, the pressing plate 21, the first spring 22 and the connecting plate 23 move downward under the action of gravity, and the pressing plate 21 loses its clamping of the material 2. After that, the material 2 will not move to the right with the cover body 9. When the cover 9 moves to the right, the material 2 can be pulled to the right for a distance, so that the free end of the material 2 can be pulled out from under the laser cutting machine 10, and the free end of the material 2 can be leveled, which is convenient for the subsequent knife setting operation. At the same time, after the free end of the material 2 is leveled, the slag generated during the laser cutting process on the free end of the material 2 can be removed. In the subsequent cutting process of the material 2, the slag can be prevented from interfering with the movement of the cutter head of the laser cutting machine 10, which may cause the displacement of the material 2.

[0051] The material 2 can be intermittently transported to the left side by the left-right movement of the cover body 9. Embodiment 2

[0052] Based on Example 1, refer to Fig.11 and Fig.12 As shown, the telescopic component is a second spring 31. One end of the second spring 31 is fixedly connected to the second bracket 14, and the other end of the second spring 31 is fixedly connected to the sliding block 33.

[0053] In this embodiment, the second bracket 14 and the sliding block 33 are connected by the second spring 31. When the width of the finished product increases, the finished product can squeeze the second spring 31 through the limiting wheel 13 and the sliding block 33, and the position of finished products of different widths can be automatically adjusted during the transportation by the conveyor belt 12.
