Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly relates to a laser cutting device for a metal stove top panel. Background Art

[0002] A laser cutter is a device that uses a laser beam with a high energy density to heat materials, causing them to melt or vaporize instantaneously, thereby achieving cutting. It has high cutting precision and speed, and can process various materials such as metals, plastics, and woods. It is widely used in fields such as manufacturing, advertising, and aerospace, promoting the high efficiency and precision of processing technologies.

[0003] In the laser cutting process of metal stove top panels, a series of intractable problems have emerged in the current technology. The traditional method of manually placing the panel at the cutting station highly depends on the skills and experience of the operator. Not only is the efficiency extremely low, but the placement error caused by human factors is extremely large, making it difficult to ensure the consistency and cutting precision of the product. After each placement, the cutting device has to perform an additional panel positioning process, which undoubtedly lengthens the equipment operation cycle and increases production costs.

[0004] To overcome the defects of manual placement, some current technologies attempt to use a method of pushing the panel to move it to the station. However, if a single panel is pushed, its efficiency is difficult to meet the requirements of large-scale production; when facing overlapping panels, the gravitational force of the upper panel makes it extremely difficult to push the bottom panel, and during the pushing process, the friction between the panels is likely to scratch the surface, causing irreversible damage to the product quality.

[0005] Based on this, a laser cutting device for a metal stove top panel is proposed. Summary of the Invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-6, the present invention provides a technical solution: A laser cutting device for a metal stove top panel, comprising a base 1, the upper end of the base 1 is connected with an operation board 2. The structure of the operation board 2 is provided to protect the base 1 and prevent the laser beam from damaging the base 1. The upper end of the base 1 is slidably connected with a moving frame 3, the moving frame 3 is slidably connected with a moving block 4, and the moving block 4 is connected with a cutting head 5. By sliding the moving block 4 on the moving frame 3 and sliding the moving frame 3 on the base 1, the laser cutting head 5 can be moved to any position above the stove top panel. One side of the base 1 is fixedly connected with a protective cover 6, which is used to protect the transfer structure of the stove top panel. The protective cover 6 is provided with a placement opening 7 and a conveying opening 8. The placement opening 7 corresponds to the upper end of the storage cylinder 10, and the conveying opening 8 corresponds to one side of the bottom groove 31. One is the inlet of the stove top panel and the other is the outlet of the stove top panel. Inside the protective cover 6, a storage cylinder 10 is fixedly connected. A separation frame 29 is slidably connected to the storage cylinder 10. The separation frame 29 is in a square frame shape and is sleeved outside the storage cylinder 10. A contact plate 33 is rotatably connected to the separation frame 29, and the contact plate 33 can be used to clamp and fix the stove top panel placed in the storage cylinder 10. A lifting frame 16 is slidably connected to the outside of the storage cylinder 10. The lifting frame 16 is also in a square frame shape and is sleeved outside the storage cylinder 10. The lifting frame 16 is connected with a lifting block 36 through a frame 27. The frame 27 and the lifting block 36 are perpendicular to each other. The upper surface of the lifting block 36 is in a horizontal state, and the upper surface of the lifting block 36 abuts against one end of the contact plate 33. The storage cylinder 10 is provided with a side groove 30 and a bottom groove 31. The structure of the side groove 30 is provided to allow one end of the contact plate 33 to slide between them, and the structure of the bottom groove 31 is convenient for the bottommost stove top panel to be pushed and displaced. One side of the storage cylinder 10 is provided with a feeding mechanism for pushing the stove top panel in the storage cylinder 10 onto the operation board 2 for laser cutting.

[0021] Specifically, as Figure 5 shown, the outside of the storage cylinder 10 is connected with fixing strips 28, and the separation frame 29 is slidably connected to the fixing strips 28. There are two fixing strips 28, and the two fixing strips 28 are vertically symmetrically connected to the outside of the storage cylinder 10. The structure of the lifting frame 16 is also slidably connected to the fixing strips 28, and the lifting frame 16 is arranged above the separation frame 29.

[0022] Specifically, as Figure 6As shown, a rotating rod 32 is connected to the separating frame 29. There are two structures of the rotating rod 32, and correspondingly, there are also two structures of the abutting plate 33, which clamp and lift the stove top panel from both sides, and this clamping effect is better. A rotating tube 35 is rotatably connected to the rotating rod 32, the abutting plate 33 is fixedly connected to the rotating tube 35, a torsion spring 34 is connected to the outside of the rotating tube 35, the torsion spring 34 is sleeved on the rotating rod 32, and the other end of the torsion spring 34 is connected to the separating frame 29. Among them, the torsion spring 34 can drive the abutting plate 33 to deflect, so that the abutting end of the abutting plate 33 deflects away from the storage cylinder 10.

[0023] Specifically, as Figure 3 and Figure 4 shown, the feeding mechanism includes a connecting strip 14. One side of the base 1 is connected with a fixing plate 9, and the base 1 and the fixing plate 9 are fixedly connected. The fixing plate 9 is fixedly connected inside the protective cover 6. A bending groove 25 is formed on the fixing plate 9. The bending groove 25 is L-shaped. The connecting strip 14 is slidably connected to one side of the bending groove 25. One side of the connecting strip 14 is connected with a telescopic cylinder 11. The telescopic cylinder 11 can drive the connecting strip 14 to move through telescoping. The telescopic cylinder 11 is rotatably connected to one side of the fixing plate 9. After the telescopic cylinder 11 is started, it operates in a reciprocating telescopic manner. After the telescopic cylinder 11 telescopes back and forth once, a stove top panel can be transported to the working plate 2; Both ends of the connecting strip 14 are respectively connected with a shaft one 19 and a shaft two 20. The shaft one 19 and the shaft two 20 are both perpendicularly connected to the connecting strip 14. A moving rod 13 is rotatably connected to the shaft one 19. One end of the moving rod 13 is connected with a pushing strip 18. The pushing strip 18 and the moving rod 13 are perpendicular to each other. A vertical rod 21 is rotatably connected to the outside of the moving rod 13. Among them, under the action of the vertical rod 21 between the moving rod 13 and the sliding frame 15, the vertical distance between the two structures remains unchanged, and the two structures can move up and down synchronously. The vertical rod 21 is slidably connected to one side of the fixing plate 9. The upper end of the vertical rod 21 is connected with a sliding frame 15. The structure of the sliding frame 15 is elliptical. One end of the shaft two 20 is limited by the structure of the sliding frame 15. One end of the sliding frame 15 is connected with a support clamp 17. The structure of the support clamp 17 is U-shaped. The support clamp 17 lifts the lifting frame 16, so that the height of the stove top panel moves up, avoiding the problem that the upper stove top panels are stacked on the bottommost stove top panel, making it difficult to move the bottommost stove top panel subsequently. The upper surface of the support clamp 17 abuts against the lower surface of the lifting frame 16. The shaft two 20 is slidably connected to the sliding frame 15.

[0024] Specifically, as Figure 4As shown, a sliding rod 24 is connected to one side of the connecting bar 14. The sliding rod 24 is vertically connected to one side of the connecting bar 14. A pushing ring 26 is rotatably connected to the sliding rod 24. The pushing ring 26 is fixedly connected to the telescopic end of the telescopic cylinder 11. By setting the pushing ring 26, the stability of the telescopic drive of the telescopic cylinder 11 is improved. During the telescopic process of the telescopic cylinder 11, the telescopic cylinder 11 itself will deflect.

[0025] Specifically, as Figure 4 shown, a cylinder frame 23 is connected to the outside of the telescopic cylinder 11. The cylinder frame 23 is rotatably connected to one side of the fixing plate 9. One side of the cylinder frame 23 is fixedly connected to the telescopic cylinder 11, and the other end of the cylinder frame 23 is a shaft structure, and this shaft structure is rotatably connected to the fixing plate 9. A circular hole structure for the rotation of the shaft structure is provided on the fixing plate 9.

[0026] Specifically, as Figure 4 shown, a sleeve ring 22 is connected to the lower end of the vertical rod 21. The sleeve ring 22 is sleeved on the moving rod 13. The sleeve ring 22 is slidably connected to the moving rod 13. When the cooking stove panel is pushed to move or the pushing bar 18 is pulled out from the storage cylinder 10, the sleeve ring 22 starts to slide on the moving rod 13.

[0027] Specifically, as Figure 4 shown, a sleeve frame 12 is fixedly connected to one side of the fixing plate 9. One end of the sleeve frame 12 is sleeved on the vertical rod 21, and the other end of the sleeve frame 12 is connected below the moving rod 13, thereby preventing the structure of the sleeve frame 12 from interfering with the movement of the connecting bar 14 and the sliding frame 15.

[0028] In summary, for a laser cutting device for a metal cooking stove panel provided in this embodiment, when laser cutting processing of the metal cooking stove panel is required, multiple panels can be sequentially placed into the storage cylinder 10 from the placement opening 7. The multiple panels are stacked in the storage cylinder 10 and wait for the structural transfer before laser cutting. The panels can also be sequentially transported to the storage cylinder 10 through structures such as a conveyor belt.

[0029] At the start of processing, the operator needs to start the telescopic cylinder 11. After the telescopic cylinder 11 is started, its structure will perform a reciprocating telescopic operation state. When the telescopic cylinder 11 extends, it can push the sliding rod 24 to slide along the bending groove 25. In the initial stage, the height of the sliding rod 24 rises, synchronously driving the sliding frame 15 and the moving rod 13 to rise in height. The support clip 17 connected to one end of the sliding frame 15 can be used to lift the lifting frame 16 to rise in height.

[0030] When the height of the lifting frame 16 rises, the lifting block 36 supports and the abutting plate 33 deflects at this time, and further uses the abutting plate 33 to improve the clamping of the stove top panel arranged in the storage cylinder 10. At this time, the position of the lowermost stove top panel remains unchanged, while the stove top panel above it rises in height under the clamping and lifting action of the abutting plate 33, causing the lowermost stove top panel to separate from the stove top panel above it.

[0031] When the height of the push bar 18 connected to one end of the moving rod 13 rises to be flush with the bottom groove 31, the telescopic cylinder 11 continues to extend at this time, and the sliding rod 24 starts to move horizontally. Since the structure of the second shaft 20 starts to slide on the sliding frame 15, the support clamp 17 stops moving in position at this time, while the first shaft 19 can push the moving rod 13 to move in the horizontal direction, and uses the push bar 18 to push the lowermost stove top panel in the storage cylinder 10 to move. The lowermost stove top surface can be easily pushed onto the working plate 2. Since the distance that the push bar 18 pushes the panel to move is fixed, and the panel is limited by the storage cylinder 10 before moving, it can ensure that the position of the stove top panel transferred to the working plate 2 remains unchanged, without the need for the laser cutting device to perform repeated positioning and calibration on its position, greatly improving the cutting processing efficiency. Subsequently, relying on the moving frame 3 to slide on the base 1 and the moving block 4 to slide on the moving frame 3, the laser cutting head 5 can be moved to any position above the panel, thereby realizing the laser cutting processing of the stove top panel.

[0032] During the laser cutting process of the stove top panel, the telescopic cylinder 11 will contract. At this time, the push bar 18 and the moving rod 13 will be withdrawn from the storage cylinder 10. When the push bar 18 is completely withdrawn, the support clamp 17 starts to descend in height. At this time, the height of the lifting frame 16 descends, and the stove top panel clamped on one side can be placed back at the bottom of the storage cylinder 10. The lifting block 36 continues to move downward until the abutting plate 33 no longer contacts the lifting block 36. At this time, the abutting plate 33 will deflect under the action of the torsion spring 34, and the deflection direction is that the end of the abutting plate 33 that abuts against the panel deflects away from the panel, causing the separation between the abutting plate 33 and the panel, so as to wait for the next time the lifting block 36 supports the abutting plate 33 to deflect and complete the clamping and lifting of the stove top panel.

[0033] After the telescopic cylinder 11 contracts to the maximum extent, it starts to extend to move the next stove top panel onto the working plate 2. When the next stove top panel enters the working plate 2, the previous stove top panel located on the working plate 2 just completes the laser cutting operation. The telescopic cycle time of the telescopic cylinder 11 can be adjusted according to the laser cutting duration of the stove top panel, so as to formulate the best cycle transmission duration of the telescopic cylinder 11.

[0034] The laser cutting device for this metal stove top panel has remarkable advantages. In terms of efficiency improvement, it completely bids farewell to the traditional manual placement and inefficient pushing methods. Through the automated operation of the feeding mechanism, the panel is quickly and orderly transported to the cutting station, greatly shortening the equipment operation cycle and conforming to the rhythm of large-scale production. In terms of quality assurance, the unique structures such as the lifting frame 16 and the abutting plate 33 cooperate effectively to solve the problem of pushing overlapping panels and avoid scratching the panel, ensuring that the panel entering the cutting station is intact. In terms of operation, the operator only needs to start the telescopic cylinder 11, and the equipment can automatically work in a preset cycle. The cycle of the telescopic cylinder 11 can be flexibly adjusted according to the cutting duration, greatly simplifying the operation process, improving the processing efficiency and product quality, and bringing a new solution to the field of laser cutting of metal stove top panels.

[0035] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
