Description

Technical Field

[0001] The invention belongs to the technical field of plate laser cutting, and relates to an automatic waste plate removal device, in particular to an automatic waste plate removal device for plate laser cutting. Background Art

[0002] Based on the focusing ability of high-energy laser beams, the laser beam is focused onto the surface of the material through a lens to form a point with high energy density. The laser energy causes the surface temperature of the material to rise rapidly to the melting point or boiling point, and the material begins to melt or evaporate. At the same time, a high-speed airflow (such as oxygen or nitrogen) coaxial with the laser beam blows away the molten or vaporized material, thereby forming a slit. Under the control of the CNC system, the laser cutting head moves along a pre-set path to achieve precise cutting.

[0003] Plate laser cutting equipment generally consists of a laser, a cutting head, a CNC system, a workbench and an auxiliary gas system.

After the positioning is completed, the lifting cylinder 48 and the limit cylinder 45 are lowered and retracted, and the top spring drives the swing rod 49 to reset. At this time, the touch control rod 52 is separated from the proximity sensor 54, ensuring that the equipment for placing the plate externally will stop pushing the plate next time.

[0049] The working principle of the present invention is as follows: the external plate moving device places the plate onto the positioning platform mechanism 43; the lifting and positioning assembly 44 and the limiting cylinder 45 are used to block and position the plate to be cut; a plurality of universal ball bearings 22 are used to support the plate and facilitate the stable sliding of the plate on the plurality of universal ball bearings 22; the lifting and positioning assembly 44 and the limiting cylinder 45 are both arranged on the platform brush plate 27 on the rear side and can extend from the two avoidance holes to position the plate to be cut and ensure stable and accurate cutting; after the positioning is completed, the lifting and positioning assembly 44 and the limiting cylinder 45 are retracted downward from the two avoidance holes to release the positioning of the plate to be cut, that is, the telescopic end of the lifting cylinder 48 is extended and retracted, thereby driving the main body of the lifting cylinder 48 to rise and fall in the reverse direction; the lifting cylinder 48 drives the installation vertical plate 53 to rise and fall, that is, drives the proximity sensor 54, the two swing bearing seats 50, the sliding limiting shaft 51, and the touch control rod 52. The swing rod 49 and the ejector rod rise and fall synchronously, so that the swing rod 49 rises and falls from the avoidance hole, and then drives the ejector rod to rise and fall, the telescopic end of the limit cylinder 45 extends from the avoidance hole at the corresponding position, and the ejector rod rises and extends from the avoidance hole at the corresponding position. After the plate hits the ejector rod, the swing rod 49 is pushed to rotate on the two swing bearing seats 50, so that the swing rod 49 slides on the sliding limit shaft 51, the swing rod 49 presses the ejection spring, and the swing rod 49 drives the touch control rod 52 to move, and the touch control rod 52 hits the proximity sensor 54, controlling the equipment for placing the plate externally to stop pushing the plate, and completing the plate positioning. After the positioning is completed, the lifting cylinder 48 and the limit cylinder 45 are lowered and retracted, and the ejection spring drives the swing rod 49 to reset. At this time, the touch control rod 52 is separated from the proximity sensor 54, ensuring that the equipment for placing the plate externally is controlled to stop pushing the plate next time; After cutting, the finished product and the waste board are connected by micro-joining to form the cutting board to be processed; The external plate moving device continues to move the cutting plate to be processed and places it on the plate placing platform 3. A plurality of universal balls 22 are used to support the plate and facilitate the plate to slide stably on the plurality of universal balls 22. The external plate moving device is reset. The telescopic end of the push cylinder 16 extends to drive the connecting member 15 to move, thereby driving the plate placing platform 3 to move on the upper end of the support frame assembly 1, that is, the guide roller 29 is engaged with the upper end of the tapered guide rail 12 to guide the plate placing platform 3, and the support wheel 42 abuts against the upper end of the side beam 17 on the right side to facilitate stable movement; The plate placing platform 3 and the cut plate to be processed pass through the material dispensing and removing mechanism 4. After completely passing through, the plate placing platform 3 and the cut plate to be processed move to the upper end of the transporting and placing platform 5; The telescopic end of the lifting cylinder 36 extends, driving the connecting plate 30 to move downward, that is, driving the two toothed material stripping plates 37 to move downward, and the locking plate 31 ensures that the two toothed material stripping plates 37 move downward synchronously, and the lifting slide shaft 33 slides inside the linear bearing 34 set at the corresponding position to ensure that the toothed material stripping plates 37 descend stably, and the toothed material stripping plates 37 are placed on the rear side of the cut plate to be processed, and the pushing assembly 2 drives the plate placement platform 3 to move backward at the upper end of the support frame assembly 1, and the toothed material stripping plates 37 push the cut plate to be processed from the plate placement platform 3, and the cut plate to be processed rolls along the unloading brush roller 26 to assist in falling and unloading; After the cut panels to be processed fall onto the upper end of the solid wood pallet 41 , the staff takes the solid wood pallet 41 out from above the plurality of storage plates 40 and places an empty solid wood pallet 41 thereon.

[0050] In summary, by cooperating with the support frame assembly 1 and the plate placing platform 3, the plate placing platform 3 can be moved forward and backward on the support frame assembly 1, which is convenient for rapid unloading; Through the cooperation between the pushing component 2 and the plate placing platform 3, the pushing component 2 drives the plate placing platform 3 to move for unloading; The material removal mechanism 4 cooperates with the plate placement platform 3 to quickly transfer and move the cut plates to be processed to the upper end of the transport and placement platform 5, and the unloading is stable and convenient, and the transport and placement platform 5 is convenient for rapid material discharge; The plate placement platform 3 cooperates with the positioning platform mechanism 43 to achieve rapid and stable transfer of the plate; The plate placement platform 3 cooperates with the lifting and positioning assembly 44 and the limiting cylinder 45 to stably and quickly position the plate to be cut, ensure accurate cutting, and accurately position and transfer it to the plate placement platform 3.
