CNC fiber laser cutting machines are generally equipped with multiple CNC workbenches. When operating, you only need to change the CNC program to cut parts of different shapes. Compared with ordinary carbon dioxide laser cutting machines, they save more space and gas consumption, have a high photoelectric conversion rate, are new energy-saving and environmentally friendly products, and are also one of the world's leading technology products; After searching, patent number CN219787005U discloses an ultra-high power CNC fiber laser cutting machine, including: a cutting machine bed and a cutting mechanism arranged on the cutting machine bed, a material pushing mechanism is fixed on the top of one end of the cutting machine bed, the material pushing mechanism includes a bottom frame and a top frame, a material feed port is formed between the top frame and the bottom frame, and limiting holes are provided on the top frame and the bottom frame, and steel balls are provided in the limiting holes; the utility model reduces the difficulty of adjusting the position of the metal plate by providing the top frame, the bottom frame and the steel balls, and also expands the size range of the metal plate that can be placed by the cutting machine with little effort; Existing ultra-high power CNC fiber laser cutting machines usually require the plates to be placed directly on the top of the cutting machine, and the cutting machine mostly uses a plate chain or mesh structure conveyor belt, which leads to certain safety hazards in the process of placing the plates, and the position adjustment is more difficult. At the same time, there is a lack of pre-positioning function for the plates to be cut, which makes it easy for the plates to shift or tilt during the placement process, affecting the accuracy of subsequent cutting.

[0003] Therefore, there is an urgent need to improve the existing ultra-high power CNC fiber laser cutting machine to solve the above-mentioned problems. Summary of the invention

At the same time, there is a lack of pre-positioning function for the plate to be cut, which causes the plate to be easily offset or tilted during the placement process, affecting the accuracy of subsequent cutting.

After positioning, the plate is driven close to the conveyor belt by controlling the first electric telescopic rod, and then the second electric telescopic rod is controlled to drive the two brackets to move away from each other until the lower end of the plate loses support and falls vertically along the positioning frame to the surface of the conveyor belt, thereby realizing the center positioning and placement of the plate.

[0006] Preferably, the upper end of the cutting machine is located at the front and rear sides of the conveyor belt and is provided with electric guide rails, and the lower ends of the front and rear sides of the movable frame are fixedly connected to the output ends of the electric guide rails; Through the above technical scheme, the electric guide rail is controlled to drive the mobile frame to move, the conveyor belt drives the plate to move, and the cutting head works together to achieve laser cutting of the plate.

Preferably, the positioning frame is designed in an L-shaped structure, a support plate is fixedly installed on one side of the two brackets close to each other, and the lower ends of the brackets, the support plate and the positioning frame are adapted to each other; Preferably, the support plates are arranged evenly in a plurality and are designed to be perpendicular to the surface of the bracket, and the lower end of the support plate is arranged parallel to the upper end of the conveyor belt; Through the above technical solution, after the spacing between the positioning frames is adjusted to be slightly larger than the width of the plate, the plate is placed on the upper end of multiple pallets, and the two positioning frames are driven to approach each other by controlling the driving motor until they are against the two ends of the plate, so that the plate can be pre-centered and effectively prevented from being offset or tilted; Preferably, the sides of the two positioning frames close to each other are arranged vertically to the upper end of the conveyor belt, a plurality of the grooves are evenly arranged at the lower end of the positioning frames, and the support plate is slidably connected to the inner side of the groove; Preferably, a mounting plate is fixedly installed on one side of the two positioning frames away from each other, the electric telescopic rod 2 is fixedly connected to the surface of the mounting plate, and the output end of the electric telescopic rod 2 extends to the lower end of the positioning frame and is fixedly connected to the side of the bracket away from each other. Through the above technical scheme, after the plate is positioned, the positioning frame is driven down by controlling the extension of the electric telescopic rod 1 until the lower end of the pallet is close to the conveyor belt and stops, and then the electric telescopic rod 2 is controlled to drive the two brackets to move away from each other until the pallet is retracted into the lower end of the positioning frame through the groove. At this time, the lower end of the plate loses its support and falls vertically along the positioning frame to the surface of the conveyor belt, thereby realizing the center positioning and placement of the plate.

The driving motor is controlled to drive the bidirectional lead screw to rotate, so that the two moving columns slide along the slide groove at the same time, so that the support plate drives the positioning frame and the bracket to move, and the distance between the two brackets is quickly adjusted, which is convenient for the erection of plates of different widths. After the distance between the positioning frames is adjusted to be slightly larger than the width of the plates, the staff will erect the plates on the upper end of the support plate to avoid direct contact with the conveyor belt, thereby improving the use of the device. To ensure the safety of the plate, the driving motor is controlled to drive the two positioning frames to move closer to each other until they are against the two ends of the plate, so as to achieve pre-centering of the plate and effectively avoid its deviation or tilt. After positioning, the positioning frame is driven down by controlling the extension of the electric telescopic rod 1 until the lower end of the support plate is close to the conveyor belt and then stops, and then the electric telescopic rod 2 is controlled to drive the two brackets to move away from each other until the support plate is retracted into the lower end of the positioning frame through the groove. At this time, the lower end of the plate loses its support and falls vertically along the positioning frame to the surface of the conveyor belt, so as to achieve the centering positioning of the plate.

By placing the plate on the bracket 11, direct contact with the conveyor belt 4 can be avoided, thereby improving the safety of the device. By controlling the two positioning frames 9, the two ends of the plate can be limited to effectively avoid its deviation or tilt. After positioning, the plate is driven close to the conveyor belt 4 by controlling the electric telescopic rod 10, and then the electric telescopic rod 2 13 is controlled to drive the two brackets 11 to move to the side away from each other until the lower end of the plate loses its support and falls vertically along the positioning frame 9 to the surface of the conveyor belt 4, thereby realizing the centering positioning and placement of the plate; The upper end of the cutting machine 1 is located at the front and rear sides of the conveyor belt 4 and is provided with electric guide rails 21, and the lower ends of the front and rear sides of the mobile frame 2 are fixedly connected to the output ends of the electric guide rails 21; Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the electric guide rail 21 is controlled to drive the moving frame 2 to move, and the conveyor belt 4 drives the plate to move, and cooperates with the cutting head 3 to achieve laser cutting of the plate, wherein the conveyor belt 4 is a plate chain or mesh structure.

After the plates are placed, the driving motor 71 is controlled to work and drive the positioning frames 9 to move away from each other until they are out of the electric guide rail 21 to avoid affecting the movement of the movable frame 2.

[0014] Embodiment 3: A support plate 81 is fixedly mounted on the right end of the moving column 8, an electric telescopic rod 10 is fixedly connected to the upper end of the support plate 81, and an output end of the electric telescopic rod 10 extends to the lower end of the support plate 81 and is fixedly connected to the upper end of the positioning frame 9; Specifically, Figure 4 , Figure 5 and Figure 6 As shown, by controlling the operation of the electric telescopic rod 10, the positioning frame 9 can be driven to rise and fall, which makes it convenient for the staff to place the plates and avoids direct contact with the conveyor belt 4, thereby improving the safety of the device. The support plate 81 is a cantilever structure, and the end of the support plate 81 is provided with a reinforcement member fixed to the surface of the movable column 8.

[0015] Embodiment 4: The positioning frame 9 is designed in an L-shaped structure, and a support plate 111 is fixedly installed on one side where the two brackets 11 are close to each other, and the lower ends of the brackets 11, the support plate 111 and the positioning frame 9 are adapted to each other; There are multiple pallets 111 evenly arranged, and the pallets 111 are designed to be perpendicular to the surface of the bracket 11, and the lower end of the pallet 111 is parallel to the upper end of the conveyor belt 4; Specifically, Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, after the spacing between the positioning frames 9 is adjusted to be slightly larger than the width of the plate, the plate is placed on the upper end of multiple support plates 111, and the two positioning frames 9 are driven to approach each other by controlling the drive motor 71 until they are against the two ends of the plate, thereby pre-centering the plate and effectively preventing it from being offset or tilted. The support plate 111 and the bracket 11 are integrally formed, and the upper end of the support plate 111 and the side where the positioning frames 9 are close to each other are smooth surfaces, and the friction with the plate is small.

[0016] Embodiment 5: The sides of the two positioning frames 9 close to each other are vertically arranged with the upper end of the conveyor belt 4, and a plurality of grooves 12 are evenly arranged at the lower end of the positioning frames 9, and the support plate 111 is slidably connected with the inner side of the groove 12; A mounting plate 91 is fixedly mounted on one side of the two positioning frames 9 away from each other, the electric telescopic rod 13 is fixedly connected to the surface of the mounting plate 91, and the output end of the electric telescopic rod 13 extends to the lower end of the positioning frame 9 and is fixedly connected to the side of the bracket 11 away from each other; Specifically, Figure 1-6 As shown, after the plate is positioned at the upper end of the support plate 111, the positioning frame 9 is driven down by controlling the extension of the electric telescopic rod 10 until the lower end of the support plate 111 is close to the conveyor belt 4 and stops. At this time, the distance between the lower end of the support plate 111 and the upper end of the conveyor belt 4 is no more than 5 mm. Then the electric telescopic rod 2 13 is controlled to drive the two brackets 11 to move away from each other until the support plate 111 is received into the lower end of the positioning frame 9 through the groove 12. At this time, the lower end of the plate loses its support and falls vertically along the positioning frame 9 to the surface of the conveyor belt 4, thereby realizing the centering positioning of the plate.

[0017] Working principle: By controlling the driving motor 71 to work and drive the bidirectional lead screw 7 to rotate, the two moving columns 8 slide along the slide groove 6 at the same time, so that the support plate 81 drives the positioning frame 9 and the bracket 11 to move, and realizes the rapid adjustment of the distance between the two brackets 11, which is convenient for the erection of plates of different widths. After adjusting the distance between the positioning frames 9 to be slightly larger than the width of the plate, the staff will erect the plate on the upper end of the support plate 111 to avoid direct contact with the conveyor belt 4, thereby improving the safety of the use of the device. By controlling the driving motor 71 to work, the two moving columns 8 drive the two positioning frames 9 to approach each other until they are against the two ends of the plate, so as to realize pre-centering of the plate and effectively avoid its displacement or tilt. After positioning is completed, the positioning frame 9 is driven to descend by controlling the extension of the electric telescopic rod 10 until the lower end of the support plate 111 is close to the conveyor belt 4 and then stops. At this time, the distance between the lower end of the support plate 111 and the upper end of the conveyor belt 4 is no more than 5mm, and then the electric telescopic rod 2 13 is controlled to drive the two brackets 1 1 moves to the side away from each other until the support plate 111 is collected into the lower end of the positioning frame 9 through the groove 12. At this time, the lower end of the plate loses its support and falls vertically along the positioning frame 9 to the surface of the conveyor belt 4 to realize the centering and placement of the plate. After the plate is placed, the positioning frames 9 are driven to move away from each other by controlling the driving motor 71 until they are separated from the upper part of the electric guide rail 21 to avoid affecting the movement of the mobile frame 2. The mobile frame 2 is driven to move by controlling the electric guide rail 21, and the conveyor belt 4 drives the plate to move, and cooperates with the work of the cutting head 3 to realize laser cutting of the plate. After the plate cutting is completed, the plate is unloaded by the conveyor belt 4. When the next round of cutting is required, the support plate 111 is driven by the electric telescopic rod 2 13 to pass through the groove 12 and extend to the outer side of the positioning frame 9, and the driving motor 71 can be controlled again to drive the two positioning frames 9 and the support 11 to move to the appropriate position above the conveyor belt 4 to pre-position the plate, which is convenient for the next round of cutting.
