Description

Technical Field

[0001] The utility model relates to the technical field of plate cutting and feeding, in particular to automatic feeding equipment for a laser cutting machine. Background Art

[0002] The laser cutting machine uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves across the material, the holes continuously form a very narrow slit, completing the cutting of the material. The laser cutting machine is mainly used to cut plates.

[0003] During the plate cutting process, the plate needs to be moved and pushed to the cutting area for cutting. For some plates with larger mass and size, if the staff manually carry and load them, it will be laborious and slow and there will be safety hazards. Therefore, some laser cutting machines are equipped with automatic loading devices to replace the manual handling and loading of workers.

[0004] The Chinese invention patent with patent application number CN202311633487.2 records an automatic loading device for a laser cutting machine, which can drive the adsorption component to move horizontally from the left side of the stand to the right side of the stand through the provided driving component. After the short side rod rotates one circle in the positive direction and the adsorption component is located on the right side of the stand and is in a horizontal state, the suction cup releases the adsorption of the plate and transfers the plate to the laser cutting machine, thereby realizing automatic loading of the plate. However, in the above-mentioned loading device, the plate is adsorbed by the negative pressure generated by the adsorption component, and the driving component drives the plate to swing, so that the plate will generate centrifugal force during the loading and moving process, so that the plate may detach from the adsorption component and be thrown down, posing a threat to surrounding personnel and equipment, thereby reducing the reliability and safety of the loading device. Utility Model Content

[0005] The purpose of the present utility model is to provide an automatic loading device for a laser cutting machine, so as to solve the problem proposed in the above background technology that the existing automatic loading device for laser cutting machines may cause the plate to fall off during loading, thereby threatening the safety of surrounding personnel and equipment, and reducing the feasibility and safety of the loading device.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatic feeding device for a laser cutting machine, comprising a fixed plate, a suction assembly connected to the bottom of the fixed plate, a swing assembly, and an anti-drop assembly provided on the fixed plate, a rotating assembly connected to the swing assembly, and the fixed plate connected to the rotating assembly;

[0007] The swing assembly is used to drive the fixed plate and the adsorption assembly to swing clockwise or counterclockwise;

[0008] The anti-fall assembly includes two pairs of clamping parts symmetrically connected on the left and right sides of the fixed plate. The anti-fall assembly also includes a moving mechanism arranged on the top of the fixed plate. The two pairs of clamping parts are connected to the moving mechanism. The anti-fall assembly also includes a driving mechanism arranged on the top of the fixed plate.

The advantage of this arrangement is that the two pairs of clamping members can be driven by the moving blocks to move stably toward each other along the guide rods, thereby ensuring that the clamping and limiting work of the plate can be carried out smoothly, thereby improving the safety and reliability of the feeding device.

[0010] Preferably, it also includes an angle adjustment component arranged on the top of the fixed plate, and the angle adjustment component is used to drive the first connecting plate to rotate on the horizontal plane. The advantage of this arrangement is that the distance between the two adjacent front and rear components can be adjusted according to the size of the plate to be adsorbed and loaded, so that the clamping part can clamp and limit the plate more stably, thereby improving the practicality and reliability of the loading component.

[0011] Preferably, the angle adjustment assembly includes two pairs of first rotating shafts symmetrically connected to the top of the fixed plate, the two pairs of the first connecting plates are symmetrically fixedly sleeved on the two pairs of first rotating shafts, and the two pairs of the first rotating shafts are symmetrically fixedly sleeved on the top ends. The angle adjustment assembly also includes two first electric push rods symmetrically fixedly connected to the top of the fixed plate, the two first electric push rods are symmetrically fixedly connected to two double-sided racks, and the two double-sided racks are respectively meshed with the two pairs of gears. The advantage of this arrangement is that the two first electric push rods push the two double-sided racks to move in opposite directions, which can stably drive the two adjacent front and rear clamping parts to move in opposite directions, thereby ensuring that the spacing between the two adjacent front and rear clamping parts can be quickly and accurately adjusted, further improving the reliability of the loading device.

[0012] Preferably, it also includes two pairs of straight rods symmetrically fixedly connected to the bottom of the two pairs of moving blocks, the bottom ends of the two pairs of straight rods are fixedly connected to circular plates, and the two pairs of clamping members are symmetrically fixedly connected to the bottom of the two pairs of circular plates.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] 1. In the utility model, by setting up the anti-dropping component, the adsorbed plates can be clamped and limited by two sets of clamping parts during the process of moving and loading the plates, thereby preventing the plates from being dropped due to their own gravity and the centrifugal force generated by the swinging when the swinging component drives the plates to swing, thereby protecting the safety of surrounding personnel and equipment and greatly improving the reliability and safety of the loading device.
