Description

Technical Field

[0001] This utility model relates to the field of plate cutting machines, and in particular to a sorting and unloading device for laser plate cutting machines with correction function. Background Technology

[0002] Laser cutting machines use a high-power laser beam focused on the surface of a metal sheet to melt or evaporate the material with thermal energy, supplemented by auxiliary gas to remove slag, thus achieving high-precision cutting. Laser cutting machines offer significant advantages such as high precision, high cutting efficiency, clean cuts, and low production costs, and are therefore widely used in various fields.

[0003] For example, the automatic sheet metal splitting and loading / unloading device described in Chinese patent CN209427703U is a typical example of a material loading / unloading device for a laser cutting machine. This device includes a frame composed of two parallel longitudinal beams, with multiple support columns on the underside of the beams. A main slide rail of the same length as the beams is mounted on the longitudinal beams, and two sets of sliders are fitted onto the main slide rails. Each set of sliders is equipped with a bidirectional adjustment mechanism, and the two bidirectional adjustment mechanisms are respectively equipped with a fork and a suction cup. The laser cutting machine tool and two sets of station unloading mechanisms are placed under the frame.

[0004] While laser cutting machines offer advantages such as high precision and high efficiency, their accompanying feeding devices (such as the structure described in CN209427703U) still have the following significant shortcomings: 1. Currently, the equipment can only handle basic materials, resulting in a mix of cut parts of different specifications and materials being output. Subsequent manual secondary sorting is required, increasing processing time and creating a significant gap compared to the automation advantages of laser cutting.

[0005] 2. The overlapping design of the bidirectional adjustment mechanism and the multi-station unloading mechanism results in a large lateral space occupation and requires additional support columns for fixation, making the installation process complex. This rigid connection method not only limits the flexibility of machine tool layout and makes adjustment and disassembly operations cumbersome, but also causes a high degree of redundancy in the spatial layout.

[0006] 3. Although a combination of forklifts and suction cups was used for handling at the end of the process, stacking, packaging, and initial sorting still required manual labor. Especially in mass production scenarios, workers need to frequently travel between the unloading point and the packaging area, which is labor-intensive and poses safety hazards.

[0110] Working principle and usage: Step 1, Pre-setting: Perform power supply testing on this device.

Place the material transfer cart onto the load-bearing carrier plate 507.

[0111] The second step is the supply of storage tank units: The storage box units are stacked in an orderly manner and placed on the electric lifting device 501.

[0113] The seventh electric push rod drives the movable gate 503 to close the "C"-shaped limit plate 502; the electric lifting device 501 starts after a delay according to the preset program, driving the storage box unit to move up one unit distance (the height of the fourth container 401); the third electric cylinder 505 and the third electric gripper start to grip the storage box unit; the second servo motor 504 drives the storage box unit to move onto the second electric roller 302 after a delay; the second electric roller 302 starts after a delay, driving the storage box unit to move.

[0114] When the storage box unit passes the limit gate, the second sensor sends a signal to the PLC controller, which then sends instructions to the fifth electric actuator 308 and the sixth electric actuator 309. The fifth electric actuator 308 starts, moving the limit gate upward; subsequently, the sixth electric actuator 309 starts after a delay, and the limit roller 310 enters the storage box unit in an orderly manner through the eighth through hole and contacts the workpiece, achieving precise correction of the workpiece position.

[0115] The third step is storage: When the processed workpiece reaches below the operating carrier plate 103, the third sensor outputs a signal to the PLC controller, and the PLC controller outputs signals to the first lead screw stepper motor module 201, the first electric cylinder 202, the first electric push rod 203, the compressor, the second electric push rod 204, and the first electric gripper 205.

The sixth sensor and the fourth sensor output signals to the PLC controller, and the PLC controller outputs signals to the first servo motor 207 and the first electric roller 301.

[0117] The first servo motor 207 rotates the workpiece to a suitable angle (i.e., close to the value of the fourth sensor, achieving a vertical position). The workpiece is then transferred from the receiving plate to the first electric roller 301. The first electric roller 301 starts, transporting the workpiece below the appropriate second mounting plate (for quality / size separation). At this time, the fifth sensor sends a signal to the PLC controller, which then outputs control signals to the second electric roller 302, the second lead screw stepper motor module 303, the second electric cylinder 304, the third electric push rod 305, the second vacuum suction cup, the fourth electric push rod 306, and the second electric gripper 307.

[0119] When fully loaded, the PLC controller outputs signals to the fourth lead screw stepper motor module 506, the second servo motor 504, the third electric cylinder 505, the third electric gripper, and the second electric roller 302.

[0120] The second electric roller 302 starts, transferring the storage box unit to the area below the third electric gripper; the third electric cylinder 505 and the third electric gripper start, gripping the storage box unit; the second servo motor 504 delays and drives the storage box unit to move onto the material transfer cart; when the material transfer cart is fully loaded, the second servo motor 504 drives the material transfer cart to move a distance to facilitate subsequent loading, and so on until it is fully loaded.
