Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, in particular to an automatic workpiece conveying device for laser cutting equipment. Background Art

[0002] Laser cutting is the process of focusing the laser light emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] After the laser cutting equipment has completed cutting the metal plates, the staff needs to remove the cut metal plates and stack them together. When a certain number is reached, they are moved together to the next process for the next step of processing. That is, the existing laser cutting equipment cannot realize automatic unloading after cutting, so that the metal plates are stacked together, thereby reducing the workload of the staff and freeing up manpower.

[0012] Preferably, a movable plug rod is fixedly provided at the lower end of the driving connecting plate, a second connecting spring is sleeved on the movable plug rod, and the movable plug rod is plugged into the movable socket.

[0013] Preferably, a supporting base plate is fixedly provided at the lower end of the movable plug-in rod, and matching rail plates are symmetrically fixedly provided on both sides of the supporting base plate. The matching rail plates are plugged into the downward channel, and second matching connecting rods are symmetrically hinged on both sides of the driving connecting plate, and the lower end of the second matching connecting rod is hinged to a movable bearing plate.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. A cutting conveyor table is provided on the cutting machine. The plates are cut on the cutting conveyor table. After the cutting is completed, the electric telescopic rod drives the cutting conveyor table to move, and drives the cut metal plates to move to realize automatic unloading. No manual unloading operation is required, which is very convenient, greatly reduces the workload of the staff, and liberates manpower.

[0018] 2. When the cutting conveyor table moves, it will drive the matching positioning plate to move toward it, so that the metal sheet can be limited and prevented from moving. This can ensure the stability of the metal sheet during the movement of the cutting conveyor table. When the movable supporting plate moves, the metal sheet will not move with the movable supporting plate, effectively preventing the metal sheet from falling from the unloading hole before reaching the unloading point.

[0019] 3. In addition, after the positioning plate is used to limit the metal sheet, as the cutting conveyor table moves further, the driving connecting plate will be pushed downward under the action of the lower pressure plate, and then the movable supporting plate will be driven to move backward under the action of the driving connecting plate, so that the unloading hole can be slowly opened. When it moves to the unloading point, the unloading hole is fully opened. At this time, the movable supporting plate no longer supports the metal sheet, so that the metal sheet can be automatically unloaded and collected under the action of its own gravity, which is very convenient.

In addition, the two ends of the first connecting spring 42 are respectively welded to the fixed carrier plate 291 and the mounting frame 43. When the inclined drive plate frame 34 moves downward, the second rotating wheel 44 contacts the inclined drive plate frame 34.

[0037] A movable plug-in rod 51 is fixedly provided at the lower end of the driving connecting plate 5, and a second connecting spring 52 is sleeved on the movable plug-in rod 51.

[0038] A supporting base plate 53 is fixedly provided at the lower end of the movable plug-in rod 51, and matching rail plates 54 are symmetrically fixedly provided on both sides of the supporting base plate 53. The matching rail plates 54 are inserted in the downward movement channel 13, and the second matching connecting rods 55 are symmetrically hinged on both sides of the driving connecting plate 5.

[0039] There are two movable supporting plates 6, which are installed in the installation groove 21, and the movable supporting plates 6 are closed together to cover the blanking through hole 23, and the limiting slides 61 are symmetrically fixed at both ends of the movable supporting plates 6. The limiting slides 61 are inserted into the limiting slide grooves 22. When the movable supporting plates 6 are closed together, they support the metal plates.

[0040] A fixed connecting plate 62 is fixedly provided on the movable supporting plate 6 , and a matching connecting strip 63 is fixedly provided on the fixed connecting plate 62 . The matching connecting strip 63 is hinged to the lower end of the second matching connecting rod 55 .

[0041] When the metal sheet is cut on the cutting machine 1, the electric telescopic rod 12 is started, and the cutting conveyor table 2 is driven to move to the outside of the cutting machine 1 under the action of the electric telescopic rod 12. During the movement, the movable connecting block 3 moves away from the connecting plate 17. In this way, the movable connecting block 3 is pulled downward under the action of the first matching connecting rod 18 to move it downward. As the movable connecting block 3 moves downward, the inclined surface of the inclined driving plate frame 34 will contact the second rotating wheel 44. In this way, the matching positioning plate 4 will be pushed to move toward each other under the action of the inclined driving plate frame 34, so that the matching positioning plate 4 can be moved toward each other. The positioning plate 4 is in contact with the metal plate, which can limit the metal plate from both sides and prevent it from moving. When the second rotating wheel 44 contacts the flat part on the inclined driving plate frame 34, the matching positioning plate 4 will no longer move. As the movable connecting block 3 moves downward, the first rotating wheel 37 will contact the matching rail plate 54. In this way, under the action of the first rotating wheel 37, the matching rail plate 54 will be pushed downward, thereby driving the driving connecting plate 5 to move downward. In this way, under the action of the second matching connecting rod 55, the two movable bearing plates 6 will be pushed to move back to each other, and under the action of the matching positioning plate 4, the metal plate cannot When the cutting machine 1 is moved to one side, the movable supporting plate 6 will not move the metal sheet when it moves, so that the metal sheet can be stably placed directly above the blanking hole 23, ensuring the stability of the metal sheet during the movement of the cutting conveyor 2, so that it can fall smoothly when it reaches the blanking point. As the movable supporting plate 6 moves slowly, the blanking hole 23 will slowly open. When the blanking hole 23 is fully opened, the movable supporting plate 6 will no longer support the metal sheet, so that the metal sheet can fall into the blanking hole 23 under the action of its own gravity. The cutting conveyor table 2 also moves to the unloading point. A container for receiving metal sheets should be placed at the unloading point in advance. In this way, when the metal sheets arrive at the unloading point, they can be unloaded into the container through the unloading hole 23 under the action of gravity, thereby realizing automatic collection of the metal sheets. It is very convenient and liberates manpower. When the unloading of the metal sheets is completed, the electric telescopic rod 12 is started to drive the cutting conveyor table 2 to move in the opposite direction and reset, which can drive the matching positioning plate 4, the driving connecting plate 5 and the movable bearing plate 6 to reset, thereby ensuring the smooth progress of the cutting work. During the cutting process, the matching positioning plate 4 does not contact the metal sheet to avoid obstruction to the cutting work.
