[0029] When using this precision vision coaxial laser cutting machine, Figure 1-Figure 7As shown, at this time, the movable box 3 is located above the left side of the bracket 1, and the right side of the bracket 1 is completely exposed to the outside, which is convenient for placing the sheet. After the sheet is placed, the first motor 2 drives the first threaded rod 201 to rotate, and the threaded connection between the first threaded rod 201 and the connecting block 302 is cooperated to make the movable box 3 move to the right to above the sheet for cutting. During processing, the second motor 401 and the second threaded rod 402 can realize the left and right position adjustment of the movable frame 403 and the laser cutting head 410, and the third motor 405 and the third threaded rod 406 can be used to cooperate with each other. The front and rear positions of the movable block 407 and the laser cutting head 410 can be adjusted, and the height of the laser cutting head 410 can be adjusted in combination with the cylinder 409. In summary, the laser cutting head 410 can be adjusted in multiple directions to perform cutting processing on the sheet material. During the cutting process, part of the metal slag generated will adhere to the support plate 104. The cut product will fall onto the filter screen 105 through the gap between the support plates 104. The product and the metal slag can be separated through the filter screen 105. The separated metal slag will fall into the slag collecting box 102 for collection for subsequent processing.

[0030] The movable box 3 is fixed to one end of the fixed rod 303, and the other end of the fixed rod 303 is fixed to the push plate 304, and the push plate 304 is in contact and slides with the filter screen 105, and the upper side of the push plate 304 is a curved surface structure;

[0031] After a sheet of material is processed, Figure 1-Figure 7 As shown, a new sheet material is placed on the left side of the bracket 1 at this time. According to the above principle, the movable box 3 is moved to the left side by the first motor 2 and the first threaded rod 201 to facilitate the processing of the new sheet material. At this time, the remaining sheet material after processing on the right side is exposed to the outside for cleaning. In summary, by replacing the left and right positions of the movable box 3, the processing of sheets at different positions can be realized, thereby realizing continuous processing without stopping to wait for the replacement of the sheet material, thereby improving the processing efficiency. In the process of the movable box 3 moving from right to left, the push plate 304 is synchronously driven to move, and the products dropped on the filter screen 105 can be pushed by the push plate 304. With the arc structure of the push plate 304, when the products are piled up during the pushing process, it is convenient for the products to be flipped forward, which can not only ensure the normal collection of the products, but also shake off the metal slag adhered to the products when the products are flipped. Finally, the pushed products enter the collection box 103 and are collected.

[0032] The slag removal mechanism 5 includes a rotating shaft 501, a gear 502, a rack 503, a disc 504, a cam 505, a chute plate 506, a connecting rod 507, a mounting plate 508 and a scraper 509. The rotating shaft 501 is connected to the movable box 3 by a bearing. One end of the rotating shaft 501 is fixedly connected to the gear 502. The gear 502 is meshed with the rack 503. The rack 503 is fixed to the bracket 1. The other end of the rotating shaft 501 is fixed to the disc 504. The disc 504 is fixed with a cam 505. , the convex shaft 505 is slidably connected to the slide plate 506, and the slide plate 506 is connected to the blowing mechanism 6, the slide plate 506 and one end of the connecting rod 507 are fixed to each other, and the connecting rod 507 is slidably connected to the bracket 1, the other end of the connecting rod 507 is fixed to the mounting plate 508, and the mounting plate 508 is fixed with scrapers 509 at equal intervals, and the scrapers 509 are in contact and slide with the support plate 104, and the scrapers 509 are located below the side of the laser cutting head 410;

[0033] The blowing mechanism 6 includes a cylinder 601, a piston 602, a one-way air inlet valve 603, a one-way air outlet valve 604, an air guide plate 605 and a nozzle 606. The cylinder 601 is fixed on the movable box 3, and the piston 602 is slidably connected to the cylinder 601, and the piston 602 and the slide plate 506 are fixed to each other; the one-way air inlet valve 603 and the one-way air outlet valve 604 are installed on the cylinder 601, and the cylinder 601 is connected to the air guide plate 605 through the one-way air outlet valve 604, and the air guide plate 605 is fixed on the movable box 3, and the nozzles 606 are fixed at equal intervals on the lower end surface of the air guide plate 605;

[0034] After a sheet of material is processed, the movable box 3 moves from right to left. Figure 1-Figure 7As shown, the movable box 3 moves synchronously to drive the rotating shaft 501, the gear 502 and the scraper 509 to move, and the transmission effect between the gear 502 and the rack 503 and the sliding effect between the convex shaft 505 and the slide plate 506 make the scraper 509 move back and forth in an orderly manner when moving with the movable box 3. The left and right reciprocating movement of the scraper 509 can provide thrust to the metal slag on the support plate 104 to facilitate the falling of the metal slag, and can realize multiple cleaning of the same position on the support plate 104 to ensure the cleaning effect of the support plate 104. When the convex shaft 505 and the slide plate 506 slide, the piston 602 is synchronously driven. It moves left and right in an orderly manner. When the piston 602 slides into the cylinder 601, the exhaust function of the cylinder 601 is realized, so that the air in the cylinder 601 enters the air guide plate 605 through the one-way air outlet valve 604 and the duct, and is ejected through the nozzle 606. The high-speed airflow ejected by the nozzle 606 can blow off the products bonded to the remaining sheet materials without manual shaking, which facilitates the collection of materials. In addition, since two cylinders 601 are provided, it can be ensured that when the movable box 3 moves, the two cylinders 601 are alternately exhausted to ensure that the nozzle 606 can continuously eject gas to avoid product omission. This is the working principle of the precision visual coaxial laser cutting machine.
