Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and more specifically to an automatic loading and unloading profile laser cutting device. Background Art

[0002] Laser cutting machine is a device that uses high-energy laser beams to cut materials. With the continuous development of modern industry, laser cutting technology has become an indispensable processing method, especially playing an important role in manufacturing, automotive industry, aerospace and other fields.

[0003] The working principle of the laser cutting machine is to use the high-energy laser beam generated by the laser to focus on the material to be cut through the optical system. The laser beam has an extremely high energy density and can instantly heat the material to the melting point or even the boiling point, thereby partially melting or vaporizing the material. At the same time, the auxiliary gas (such as nitrogen, oxygen or compressed air) is sprayed into the cutting area through the nozzle coaxially with the laser beam to blow away the material melted or vaporized due to the high temperature to form an incision. In addition, it cooperates with multi-axial precise drive to realize the position adjustment of the cutting point to meet the precision cutting needs of multi-dimensional special-shaped materials.

[0004] Although auxiliary gas is sprayed into the laser cutting area through a nozzle, it can clean up the melted or vaporized materials (metal debris), but the splashing metal debris will pollute the processing workshop. These fine metal particles may adhere to the surface of the equipment, accumulate in the working area, and may even enter the moving parts of the equipment, thereby affecting the normal operation and processing accuracy of the equipment. In addition, the completion of the metal processing process, including alignment, cutting and cleaning stages, requires cooperation between multiple modules, resulting in high production and operation costs and complex equipment structure.

[0039] The exhaust valve 605 passes through the limiting ring 104 , and the length of the exhaust valve 605 is set to at least meet the movement requirement of the laser cutting gun 303 carrying the protective component 4 .

[0040] Working principle of the present invention:

[0041] The profile is transported to the processing area by the conveying assembly 7;

[0042] When the profile to be processed arrives at the processing area, the X-axis, Y-axis and Z-axis adjustment parts of the site adjustment component 2 are responsible for the adjustment and movement in the left-right, front-back and up-down directions respectively. These directions are defined by the right-hand rectangular coordinate system and have the characteristics of being perpendicular to each other. The adjustment of each axis is equipped with a corresponding precision mechanical structure and servo system; for example: the Y-axis adjustment part is responsible for the movement in the front-back direction. It is driven by the servo motor 207 in this part. The output shaft of the servo motor 207 drives the gear 206 assembled therewith to rotate forward or reverse. The rotating gear 206 is driven and stepped along the inner wall of the toothed chain 204, so that the toothed chain 204 passing through the guide ring 205 is in the receiving groove 203. When rewinding and unreeling, the stepping force is transmitted to the X-axis adjustment part and the Z-axis adjustment part through the frame 208, so that the X-axis and Z-axis adjustment parts move horizontally forward and backward along the track 201 by means of the slider 202 of the Y-axis adjustment part to adjust the position of the cutting component 3 in the Y-axis direction. Similarly, the X-axis adjustment part and the Z-axis adjustment part adjust the position of the cutting component 3 in the X or Z-axis direction by the same principle to dispatch the cutting component 3 to the predetermined processing position, and then the telescopic end of the hydraulic rod 301 drives the angle adjuster 302 and the laser cutting gun 303 to move downward to send the laser cutting gun 303 to the cutting point. At this time, the bottom cover 402 just touches and presses on the surface of the profile, so that the cutting point is covered therein;

[0043] When the bottom cover 402 touches the surface of the profile, the exhaust fan connected to the connecting pipe 504 starts, and the continuous airflow passes through the micropores on the side wall of the bottom cover 402, the top cover 401, the exhaust valve 605, the air cavity of the air pipe 601, the air hose 606 and the receiving tray 501 in sequence, and then passes through the filter cover 503 and is discharged through the connecting pipe 504, so that the air cavities of the left and right air pipes 601 and the buffer cavity connected thereto form a negative pressure, causing the left and right piston rods 602 to gradually withdraw from the buffer cavity, and compress the spring 603 to converge inward, and the piston rod 602 carries The T-shaped frame 608 and the electric clamp 609 gradually approach the profile until the electric clamp 609 passes through the opening of the side wall of the conveyor frame 701 and the two sides of the profile are embedded in the jaws of the electric clamp 609. Then the electric clamp 609 starts and bites the profile tightly to achieve stable clamping of the profile. The cutting angle is then adjusted by the angle adjuster 302. Finally, the laser beam generated by the laser cutting gun 303 cuts the profile. The metal scraps generated by the cutting cannot escape from the bottom cover 402, but are transported to the hopper 502 with the flow of high-pressure airflow for centralized storage.

[0044] After the cutting is completed, the electric clamp 609 cancels its clamping of the profile, and the negative pressure air circuit is also canceled. Then, the piston rod 602 carries the T-shaped frame 608 and the electric clamp 609 to reset under the elastic force of the spring 603. During the above-mentioned telescopic movement, the piston rod 602 will drive the brush plate 607 connected to its end to move back and forth. The brush plate 607 moving back and forth can push the leaked debris accumulated in the receiving tray 501 to approach the drop port of the receiving tray 501, thereby reducing the accumulation rate of the leaked debris in the receiving tray 501 and maintaining the efficient and sustainable operation of the equipment.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
