Description

Technical Field

[0001] This utility model relates to a two-sided lifting plate feeding machine. Background Technology

[0002] The double-sided lifting board feeding machine is an automated auxiliary equipment designed specifically for board processing centers. Its core structure consists of lifting devices installed on the left and right sides of the stack of boards, which are used to lift the entire stack of boards and continuously and accurately raise the top layer of boards to a fixed height so that the robotic arm can pick up the materials. Its main function is to automate the board feeding, replace traditional manual handling, and greatly improve production efficiency.

[0003] The operator uses a forklift to place a stack of boards onto the material rack of the loading machine. The lifting mechanisms on both sides rise simultaneously, lifting the entire stack until the top board reaches a fixed height that the robotic arm can pick up. The separating device then operates to ensure that only the top board is separated. The crossbeam moves, and the vacuum suction cup above it descends and firmly holds the board. The crossbeam carries the board to the worktable of the processing machine, where it is precisely placed in position. After one board is removed, the lifting mechanisms on both sides immediately rise slightly to compensate for the reduced height of the stack, allowing the next board to return to the precise picking position, ready for the next cycle.

[0004] The main drawbacks of existing technologies are their limited functionality and insufficient adaptability. They lack precise position and angle adjustment capabilities, making it impossible to flexibly adapt to the needs of gripping sheet metal of different sizes and orientations. They also lack adaptive gripping mechanisms for materials such as magnetic or non-magnetic materials. Material changes require manual intervention, reducing efficiency. Furthermore, the gripping method is limited, and there is a risk of sheet metal falling off uneven surfaces. This results in low levels of equipment intelligence, poor production flexibility, reliance on manual labor, and a high risk of downtime. To address these issues, a two-sided lifting sheet metal feeder is proposed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3 This utility model provides an embodiment of a two-sided lifting plate feeding machine, including a gantry frame 1. A motor 2 is fixedly connected to the outer wall of the gantry frame 1. A screw 3 is fixedly connected to the output end of the motor 2. The end of the screw 3 away from the motor 2 is rotatably connected to the inner surface of the gantry frame 1. A slide 4 is threadedly connected to the outer wall of the screw 3 via a nut. A slot is opened on the outer wall of the gantry frame 1, and the inner wall of the slot is adapted to the outer wall of the slide 4. A second motor 5 is fixedly connected to the top of the slide 4. A second screw 6 is fixedly connected to the output end of the second motor 5. The screw 6 is located away from the second motor 5. One end of the screw is rotatably connected to the inner surface of the slide 4. The outer wall of the screw 6 is also connected to the lifting seat 7 by a nut thread. The outer wall of the lifting seat 7 fits against the outer wall of the slide 4. The top of the lifting seat 7 is fixedly connected to the cylinder 8. The cylinder 8 with a magnetic ring can monitor the piston position in real time and is used to achieve short-distance precise height adjustment of the lifting frame 9, making up for the shortcomings of the screw drive in micro-adjustment. The output end of the cylinder 8 is fixedly connected to the lifting frame 9. The lifting frame 9 is made of lightweight alloy material, which drives the lifting frame 9 and the gripping components below to move synchronously, reducing the load while ensuring structural strength.

[0036] Reference Figures 1-3A motor 10 is fixedly connected to the outer wall of the lifting frame 9, equipped with a reduction gearbox to reduce the output speed and increase the torque, providing driving force for the rotation of the lifting plate 11 and ensuring stability during angle adjustment. The output end of the motor 10 is fixedly connected to the lifting plate 11, and a key connection is used to achieve reliable torque transmission, driving the lifting plate 11 and the gripping components above it to rotate and adjust the angle to meet the plate posture requirements of different workstations. An electric push rod 12 is fixedly connected to the top of the lifting plate 11, providing power for the up and down movement of the electromagnetic plate 14, realizing precise lifting control of the electromagnetic plate 14. The output end of the electric push rod 12 is fixedly connected to the electromagnetic plate 14, and a guide rod 13 is fixedly connected to the top of the electromagnetic plate 14. The guide rod 13 passes through the lifting plate 11 and is slidably connected to the outer wall of the lifting plate 11. A motor 15 is fixedly connected to the top of the lifting plate 11. The output end of the machine 15 is fixedly connected to a bidirectional lead screw 16. The outer wall of the bidirectional lead screw 16 is also connected to a clamping plate 17 by a nut thread. The clamping plate 17 is set in a U-shape structure. The outer wall of the clamping plate 17 fits against the outer wall of the lifting plate 11. A vacuum pump 18 is fixedly connected to the outer wall of the clamping plate 17. An oil-free vacuum pump 18 is selected to ensure stable vacuum. It is used to generate negative pressure to provide adsorption force and enhance the reliability of the clamping plate 17 in gripping non-magnetic plates. The output end of the vacuum pump 18 is fixedly connected to a vacuum suction cup 19 through a pipe. The pipe is a negative pressure resistant hose to transmit the negative pressure generated by the vacuum pump 18 to the vacuum suction cup 19 to ensure minimal negative pressure loss. The vacuum suction cup 19 is set on the outer wall of the clamping plate 17 on the side close to the electromagnetic plate 14. The suction cup is made of wear-resistant rubber to facilitate direct contact and adsorption of the plate, while increasing the friction with the plate.

[0037] Reference Figures 3-4 Electromagnetic plates 22 are fixedly connected to the bottom of the electromagnetic plate 14. The electromagnetic plates 22 are made of high-permeability material. They generate magnetic force to attract magnetic plates when energized, and the magnetic force disappears quickly when the power is off, facilitating the release of the plates. Several groups of electromagnetic plates 22 are arranged in a hexagonal configuration. This hexagonal structure allows for seamless arrangement, increasing the contact area with the plates and improving adsorption stability. Furthermore, selective energization can be applied according to the plate size, saving energy. An arc-shaped guide rail 20 is fixedly connected to the outer wall of the lifting frame 9. The cross-section is dovetail-shaped, providing trajectory support for the sliding frame 21 and preventing the sliding frame 21 from detaching from the guide rail. The arc-shaped guide rail 20 is fixedly connected to the outer wall of the lifting frame 9 away from the slide block 4. The arc-shaped guide rail 20 is semi-circular. The sliding frame 21 is slidably connected to the inner wall of the arc-shaped guide rail 20. The bottom end of the sliding frame 21 is fixedly connected to the top of the lifting plate 11 by bolt fastening, ensuring that the lifting plate 11 and the sliding frame 21 move synchronously, improving the stability during rotation and preventing the lifting plate 11 from shaking during rotation.

[0038] Working principle: Motor 2 on gantry 1 starts running, and its output drives screw 3 to rotate. Since slide 4 is threadedly connected to screw 3 through a nut sleeve, and the outer wall of slide 4 matches the slot on gantry 1, the rotation of screw 3 is converted into smooth sliding of slide 4 along the length of gantry 1. This drives the subsequent actuator on slide 4 to adjust its lateral position to align with the area to be gripped on the sheet metal. When slide 4 moves to the target lateral position, motor 5 on top of slide 4 starts, driving screw 6 to rotate, and lifting seat 7... The screw 6 is connected to the nut sleeve and fits against the outer wall of the slide 4. The rotation of the screw 6 causes the lifting seat 7 to move up and down along the height direction of the slide 4, which in turn drives the cylinder 8, lifting frame 9 and other components installed on the lifting seat 7 to adjust the longitudinal height, so that the gripping mechanism below the lifting frame 9 approaches the sheet material. Then, the cylinder 8 is activated, and its output end pushes the lifting frame 9 to further fine-tune the height, ensuring that the gripping component on the lifting plate 11 is accurately aligned with the sheet material. At this time, if the sheet material is magnetic, the electric push rod 12 at the top of the lifting plate 11 extends and pushes... As the moving electromagnetic plate 14 moves downward, several sets of hexagonal electromagnetic plates 22 at the bottom of the electromagnetic plate 14 are energized to generate magnetic force, attracting the plate material. If the plate material is non-magnetic, the motor 15 at the top of the lifting plate 11 starts, driving the bidirectional lead screw 16 to rotate. The U-shaped clamping plates 17 on both sides are connected to the bidirectional lead screw 16 through nut sleeves. Driven by the bidirectional lead screw 16, they move closer to each other, clamping the sides of the plate material. At the same time, the vacuum pump 18 on the clamping plate 17 starts, creating negative pressure in the vacuum suction cup 19 through the pipe, further adsorbing the surface of the plate material and ensuring a firm grip. After the material is grasped, motor 25 reverses to drive the lifting seat 7 to rise, raising the sheet to the target height. Then motor 12 runs again, driving the slide 4 to move to the target conveying position of the sheet. If the angle of the sheet needs to be adjusted, motor 410 on the outer wall of the lifting frame 9 starts, driving the lifting plate 11 to rotate. At this time, the sliding frame 21 fixed at the top of the lifting plate 11 slides along the semi-circular arc guide rail 20 on the lifting frame 9, providing guidance and support for the rotation of the lifting plate 11, ensuring the stability of the sheet during the rotation process, and finally completing the transfer and delivery of the sheet.
