Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and specifically discloses a laser cutting machine feeding device. Background Technology

[0002] A laser cutting machine is a high-efficiency processing device that uses a high-energy-density laser beam to locally irradiate a workpiece, causing the material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow removes the molten material, thus achieving cutting. It is widely used in the processing of sheet metal, especially in operations requiring batch and precise cutting of metal sheets of the same specifications, where its high efficiency and precision are particularly prominent. Gantry-type laser cutting machines, due to their stable structure and large processing range, are commonly used for handling large-sized metal sheets.

[0003] In existing technologies, the metal sheet to be cut is typically supported by a toothed plate inside the machine tool, and the cutting operation is performed by a gantry laser cutting machine. However, in existing technologies, the process of placing the metal sheet onto the cutting machine's toothed plate usually relies on manual operation. Operators need to manually move the sheet onto the toothed plate in the processing area. On the one hand, relying entirely on human judgment and manual positioning makes it difficult to guarantee the accuracy and consistency of each loading. Deviations in the placement of the sheet can cause the processing origin to shift, affecting not only cutting accuracy but also potentially leading to material waste or product scrap, especially since metal sheets are often quite heavy. On the other hand, due to the sharp toothed structure on the surface of the toothed plate, there is a risk of scratches during manual handling, posing a significant safety hazard.

[0004] Therefore, a laser cutting machine feeding device is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a feeding device for a laser cutting machine, which can effectively position the metal sheet to prevent the processing origin from shifting due to manual placement deviation, thereby improving cutting accuracy and avoiding material waste. At the same time, it realizes the automatic transfer and placement of the metal sheet to the toothed plate area, eliminating the need for operators to directly contact the toothed support structure, eliminating the risk of scratches, and significantly improving operational safety.

[0006] This utility model is implemented as follows: a laser cutting machine feeding device includes a base plate and a metal plate. A frame is provided above the base plate. Multiple toothed plates are fixedly connected inside the frame. A gantry laser cutting machine is provided on the upper side of the frame. A positioning mechanism and a transfer mechanism are provided on the upper side of the base plate. The positioning mechanism includes a flat plate, with two positioning end plates fixedly connected to the upper end of the flat plate. Multiple support rollers that abut against the bottom end of the metal plate are rotatably connected between the two positioning end plates. A positioning roller that abuts against the left end of the metal plate is also rotatably connected between the two positioning end plates. The transfer mechanism includes a mounting frame fixedly connected to the upper end of a base plate. A turntable is rotatably connected to the upper end of the mounting frame. A servo motor with its output end fixedly connected to the turntable is installed inside the mounting frame. A steering plate is fixedly connected to the upper end of the turntable. A first electric actuator is fixedly connected to the upper end of the steering plate. A crossbeam is fixedly connected to the output end of the first electric actuator. An air extraction cylinder is fixedly connected through the upper end of the crossbeam. A second electric actuator is installed at the upper end of the air extraction cylinder. The output end of the second electric actuator passes through the upper end of the air extraction cylinder and is fixedly connected to a disc. A hollow disc is fixedly connected to the outer wall of the air extraction cylinder. A suction cup is fixedly connected to the lower end of the hollow disc.

[0007] As a preferred embodiment of the laser cutting machine feeding device of this utility model, the upper end of the steering plate is fixedly connected to two guide cylinders, and the interior of each of the two guide cylinders is slidably connected to a guide rod that is fixedly connected to the crossbeam.

[0008] As a preferred embodiment of the laser cutting machine feeding device of this utility model, a controller is installed at the upper end of the crossbeam.

[0009] As a preferred embodiment of the laser cutting machine feeding device of this utility model, the outer wall of the disc is provided with two sealing rings that abut against the inner wall of the air extraction cylinder through two grooves.

[0010] As a preferred embodiment of the laser cutting machine feeding device of this utility model, the lower end of the hollow disk is provided with a through hole, and the top of the inner wall of the suction cup is provided with an air hole communicating with the through hole.

[0011] As a preferred embodiment of the laser cutting machine feeding device of this utility model, two first support plates are fixedly connected between the frame and the base plate, and two second support plates are fixedly connected between the flat plate and the base plate.

[0012] As a preferred embodiment of the laser cutting machine feeding device of this utility model, the suction cup is made of nitrile rubber.

[0013] The beneficial effects of this utility model are: 1. The operator places the metal sheet on the support rollers of the positioning mechanism and uses the positioning rollers for limiting the position, along with two positioning end plates to complete the initial positioning. The transfer mechanism then starts, and the electric push rod drives the vacuum cylinder to descend, causing the suction cup to contact the surface of the sheet. Subsequently, a negative pressure is created inside the suction cup by the upward movement of the disc, firmly adhering the sheet. The servo motor drives the turntable to rotate 180 degrees, precisely transferring the sheet above the cutting machine's toothed plate. After the electric push rod descends to place the sheet, the vacuum is released. The entire loading process requires no direct manual handling, and the operator does not need to contact the toothed support structure, completely eliminating the risk of scratches and significantly improving operational safety.

[0014] 2. This device uses a positioning mechanism to initially position the sheet metal, and then a transfer mechanism to perform stable gripping, rotating, and placing actions, ensuring the consistency of the loading position each time. This prevents the processing origin from shifting due to manual placement deviations, thereby significantly improving the precision of laser cutting and effectively avoiding material waste caused by misalignment.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-5 A laser cutting machine feeding device includes a base plate 1 and a metal plate 8. A frame 2 is provided above the base plate 1. Multiple toothed plates 3 are fixedly connected inside the frame 2. A gantry laser cutting machine 25 is provided on the upper side of the frame 2. A positioning mechanism and a transfer mechanism are provided on the upper side of the base plate 1. The positioning mechanism includes a flat plate 4, with two positioning end plates 6 fixedly connected to the upper end of the flat plate 4. Multiple support rollers 5 that abut against the bottom end of the metal plate 8 are rotatably connected between the two positioning end plates 6. A positioning roller 7 that abuts against the left end of the metal plate 8 is rotatably connected between the two positioning end plates 6. The transfer mechanism includes a mounting frame 9 fixedly connected to the upper end of the base plate 1. A turntable 11 is rotatably connected to the upper end of the mounting frame 9. A servo motor 10 with its output end fixedly connected to the turntable 11 is installed inside the mounting frame 9. A steering plate 12 is fixedly connected to the upper end of the turntable 11. A first electric push rod 13 is fixedly connected to the upper end of the steering plate 12. A crossbeam 14 is fixedly connected to the output end of the first electric push rod 13. An air extraction cylinder 15 is fixedly connected through the upper end of the crossbeam 14. A second electric push rod 16 is installed at the upper end of the air extraction cylinder 15. A disc 17 is fixedly connected through the upper end of the air extraction cylinder 15. A hollow disc 19 is fixedly connected to the outer wall of the air extraction cylinder 15. A suction cup 20 is fixedly connected to the lower end of the hollow disc 19.

[0020] In this embodiment: First, the operator places the metal sheet 8 to be processed on multiple support rollers 5, positioning the metal sheet 8 between two positioning end plates 6. Then, the operator pushes the metal sheet 8 to the left, causing its left end to abut against the outer wall of the positioning roller 7. Since the distance between the two positioning end plates 6 matches the width of the front and rear sides of the metal sheet 8, and through the support of the multiple support rollers 5, combined with the limiting effect of the positioning roller 7 on the metal sheet 8, the initial placement position of the metal sheet 8 is thus positioned.

[0021] After positioning is complete, the suction cup 20 is positioned directly above the metal plate 8. The first electric actuator 13 is activated, pushing the crossbeam 14 downwards. The suction cylinder 15 and hollow disc 19, fixedly connected to the crossbeam 14, descend accordingly until the suction cup 20 makes tight contact with the upper surface of the metal plate 8. Subsequently, the output end of the second electric actuator 16 drives the disc 17 to move upwards inside the suction cylinder 15, thereby creating a negative pressure within the cavity of the suction cylinder 15, hollow disc 19, and suction cup 20, firmly adhering the metal plate 8 to the lower end of the suction cup 20.

[0022] Next, the first electric actuator 13 moves the metal plate 8 upward. Then, the servo motor 10 drives the turntable 11 to rotate 180° clockwise, thereby causing the steering plate 12, the first electric actuator 13, and the fixed metal plate 8 to rotate 180° around the turntable 11, transferring the metal plate 8 directly above the toothed plate 3.

[0023] Finally, the first electric actuator 13 moves the crossbeam 14 downwards, smoothly placing the metal sheet 8 onto the toothed plate 3. The second electric actuator 16 then pushes the disc 17 down, breaking the vacuum environment and releasing the suction cup 20. The transfer mechanism then resets, ready for the next loading operation. Operators no longer need to directly contact the toothed support structure, completely eliminating the risk of scratches associated with manual handling and significantly improving operational safety.

[0024] The gantry laser cutting machine 25 then moves forward, positioning the metal sheet 8 directly beneath it, and then performs the cutting operation according to the set program. Throughout the process, the positioning mechanism accurately positions the initial placement of the metal sheet 8, and the transfer mechanism automatically picks up and places the metal sheet 8, ensuring consistent placement each time. This effectively positions the metal sheet 8, preventing deviations in the processing origin due to manual placement, thereby improving cutting accuracy and avoiding material waste.

[0025] As a technical optimization of this utility model, two guide cylinders 23 are fixedly connected to the upper end of the steering plate 12, and guide rods 24 that are fixedly connected to the crossbeam 14 are slidably connected inside the two guide cylinders 23.

[0026] In this embodiment, the two guide cylinders 23 are slidably engaged with the two guide rods 24, thereby improving the stability of the lifting and lowering of the crossbeam 14.

[0027] As a technical optimization of this utility model, a controller 22 is installed on the upper end of the crossbeam 14.

[0028] In this embodiment, the controller 22 is used to control the entire feeding process. It sends precise start / stop, rotation direction, extension / retraction stroke, and other commands to the servo motor 10, the first electric push rod 13, and the second electric push rod 16 in sequence, directing each execution component to move in an orderly manner.

[0029] As a technical optimization of this utility model, the outer wall of the disc 17 is provided with two sealing rings 18 that abut against the inner wall of the suction cylinder 15 through two grooves.

[0030] In this embodiment: When the second electric actuator 16 pushes the disk 17 to move up and down inside the vacuum cylinder 15, the two sealing rings 18 always keep in close contact with the inner wall of the vacuum cylinder 15 to prevent gas from passing through the gap between the vacuum cylinder 15 and the disk 17 during vacuuming.

[0031] As a technical optimization of this utility model, a through hole 21 is provided at the lower end of the hollow disk 19, and an air hole communicating with the through hole 21 is provided at the top of the inner wall of the suction cup 20.

[0032] In this embodiment: by providing through holes 21 and connecting the air holes to each other, the suction cup 20 inside the hollow disk 19 can be vented.

[0033] As a technical optimization of this utility model, two first support plates are fixedly connected between the frame 2 and the base plate 1, and two second support plates are fixedly connected between the flat plate 4 and the base plate 1.

[0034] In this embodiment, by setting two first support plates and two second support plates, the frame 2 and the flat plate 4 are respectively provided with support and fixation.

[0035] As a technical optimization of this utility model, the suction cup 20 is made of nitrile rubber.

[0036] In this embodiment, nitrile rubber is used as the material of the suction cup 20. It has good elasticity, sealing properties and wear resistance, which ensures the stability of operation and extends the service life of the suction cup 20.

[0037] The working principle and usage process of this utility model are as follows: First, the operator places the metal sheet 8 to be processed on multiple support rollers 5, positioning the metal sheet 8 between two positioning end plates 6. Then, the operator pushes the metal sheet 8 to the left, causing the left end of the metal sheet 8 to abut against the outer wall of the positioning roller 7. Since the distance between the two positioning end plates 6 is adapted to the width of the front and rear sides of the metal sheet 8, and through the support of the multiple support rollers 5, combined with the limiting effect of the positioning roller 7 on the metal sheet 8, the initial placement position of the metal sheet 8 is thus positioned.

[0038] After positioning is complete, the suction cup 20 is positioned directly above the metal plate 8. The first electric actuator 13 is activated to push the crossbeam 14 downwards. The suction cylinder 15 and hollow disc 19, fixedly connected to the crossbeam 14, descend accordingly until the suction cup 20 makes tight contact with the upper surface of the metal plate 8. Subsequently, the output end of the second electric actuator 16 drives the disc 17 to move upwards inside the suction cylinder 15. The two sealing rings 18 on the outer wall of the disc 17 ensure a tight seal during movement, thereby creating a negative pressure within the suction cylinder 15, the hollow disc 19, and the cavity of the suction cup 20 connected to the through hole 21 and air vent, firmly adhering the metal plate 8 to the lower end of the suction cup 20.

[0039] Next, the first electric actuator 13 moves the metal plate 8 upward. Then, the servo motor 10 drives the turntable 11 to rotate 180° clockwise, thereby causing the steering plate 12, the first electric actuator 13, and the fixed metal plate 8 to rotate 180° around the turntable 11, transferring the metal plate 8 directly above the toothed plate 3.

[0040] Finally, the first electric actuator 13 moves the crossbeam 14 downwards, smoothly placing the metal sheet 8 onto the toothed plate 3. The second electric actuator 16 then pushes the disc 17 down, breaking the vacuum environment and releasing the suction cup 20. The transfer mechanism then resets, ready for the next loading operation. Operators no longer need to directly contact the toothed support structure, completely eliminating the risk of scratches associated with manual handling and significantly improving operational safety.

[0041] The gantry laser cutting machine 25 then moves forward, positioning the metal sheet 8 directly beneath it, and then performs the cutting operation according to the set program. Throughout the process, the positioning mechanism accurately positions the initial placement of the metal sheet 8, and the transfer mechanism automatically picks up and places the metal sheet 8, ensuring consistent placement each time. This effectively positions the metal sheet 8, preventing deviations in the processing origin due to manual placement, thereby improving cutting accuracy and avoiding material waste.
