DETAILED DESCRIPTION

[0028] The technical solution in the embodiment of the present application is to solve the deficiencies in the related laser cutting machine technology referred to in the above background technology, and the overall idea is as follows:

[0029] Embodiment 1:

[0030] like Figure 1-Figure 6 As shown, a laser cutting machine for facilitating loading and unloading of plates comprises a frame 1 and a laser cutting head moving auxiliary mechanism 3 installed across the top of the frame 1 and a laser cutting head 5 installed thereon. The frame 1 comprises two side frames 12 and extension rods 14 connected in pairs at both ends of the two side frames 12. The outer ends of the two extension rods 14 at each end are commonly fixed with a mounting plate 15; and further comprises:

[0031] The plate conveying mechanism 4 includes a driving member 41 disposed on two mounting plates 15 and two conveying racks 42 disposed thereon. The driving member 41 can drive any one of the two conveying racks 42 to move to below the laser cutting head 5 .

[0032] In this embodiment, the driving member 41 can be used to drive any conveyor rack 42 to move to the bottom of the laser cutting head 5, and the plate to be cut is placed on the conveyor rack 42 that has not moved directly under the laser cutting head 5, waiting for the next round of cutting operation. After the plate on the previous conveyor rack 42 is cut, the driving member 41 is immediately started to move the next conveyor rack 42 to the bottom of the laser cutting head 5 for laser cutting, and the new plate to be processed is placed on the previous conveyor rack 42. Such a design facilitates the continuity of cutting by the laser cutting machine and helps improve the working efficiency of the laser cutting machine.

[0033] The driving member 41 includes a servo motor A411 installed on the inner side of one of the mounting plates 15, the output end of the servo motor A411 is connected to a ball screw pair 412, the outer wall of the ball screw pair 412 is rotatably connected to two nut seats 413 in pairs, and also includes guide rods 414 whose two ends are respectively connected to the inner sides of the two mounting plates 15, and the guide rods 414 are provided with sliding sleeves 415 in pairs for sliding, and a connecting rod 416 is fixed between the sliding sleeves 415 and the corresponding nut seats 413, and the two sliding sleeves 415 are both connected to the conveying frame 42.

[0034] Specifically, the servo motor A411 is started to rotate the ball screw pair 412, and at the same time, under the guidance and cooperation of the guide rod 414 and the sleeve 415, the nut seat 413 is translated on the ball screw pair 412, so that the conveying frame 42 is translated along with the nut seat 413, so that the plates placed on the two conveying frames 42 can switch between the cutting position and the position to be cut, which effectively improves the continuity of plate cutting.

[0035] The conveying rack 42 includes a fixed rod A421 fixed on the upper part of the sliding sleeve 415, and a pair of fixed rods B422 perpendicular to the fixed rod A421 are fixed thereto, and placement rods 423 are equidistantly fixed on the fixed rod B422. All the placement rods 423 indirectly arranged on the upper part of the same sliding sleeve 415 together constitute a storage rack for placing plates.

[0036] Specifically, the storage rack formed by the fixing rod A421, the fixing rod B422 and all the placement rods 423 is convenient for carrying and placing the plates.

[0037] Reinforcement rods 13 are fixed to both ends of the opposite sides of the two side frames 12 .

[0038] Specifically, the design of the reinforcement rod 13 facilitates improving the firmness of the connection between the two side frames 12. It should also be noted that the specific shape of the side frame 12 is an inverted U-shaped design.

[0039] A bottom plate 11 extending to below the two conveying frames 42 is fixed to the bottom of the two side frames 12 , and self-locking universal wheels (not shown) are installed near the four corners of the bottom of the bottom plate 11 .

[0040] Specifically, Figure 1 and Figure 2 As shown, the design of the base plate 11 can improve the stability of the laser cutting machine during processing. Uncut plates can be stacked on the base plate 11. The design of the self-locking universal wheel is conducive to moving the laser cutting equipment, thereby improving the convenience of moving the laser cutting machine.

[0041] It should also be noted that in actual operations, a robotic arm with a suction cup (not shown) can be installed on the side of the laser cutting machine equipment. The robotic arm can be used to move the plate to be processed on the base plate 11 to the conveyor rack 42 that is not directly under the laser cutting head 5, which is convenient for loading the laser cutting machine. The robotic arm can also be used to move the processed plate out of the conveyor rack 42 to facilitate unloading of the laser cutting machine.

[0042] L-shaped supports 16 are fixed to the upper parts of the opposite sides of the two side frames 12, and a dust receiving drawer 2 located on the bottom outer side of the driving member 41 is slidably placed between the two L-shaped supports 16.

[0043] Specifically, the cooperation between the L-shaped support 16 and the dust collecting drawer 2 makes it easy to collect dust falling during the cutting process of the laser cutting machine, and to remove the dust collecting drawer 2 from the laser cutting machine for processing.

[0044] The laser cutting head moving auxiliary mechanism 3 includes a slide rail 31 and a gear belt A32 fixed on the top of two side frames 12, an inverted U-shaped moving frame 33 is slidably connected between the two slide rails 31, and a Y-axis moving member 34 meshing with the gear belt A32 is fixed on the side wall of the inverted U-shaped moving frame 33;

[0046] Specifically, the gear transmission structure A343 is composed of two gears C and an internal tooth belt A meshing with the two gears. The two gears C are respectively connected and fixed to the gear A344 and the output end of the servo motor B342. The servo motor B342 is started to drive the gear transmission structure A343 to operate, and indirectly drive the gear A344 to rotate on the gear belt A32, so that the laser cutting head moving auxiliary mechanism 3 can be moved to the specified position on the slide rail 31, so that the laser cutting head 5 can be flexibly moved to the specified position on the Y axis.

[0047] A gear belt B35 is fixed on the top of the inverted U-shaped moving frame 33, and an X-axis moving member 36 meshing with the gear belt B35 is also provided on the top of the inverted U-shaped moving frame 33;

[0048] The X-axis moving member 36 includes a sliding frame 361 slidably connected to the top of the inverted U-shaped moving frame 33, a servo motor C362 is installed on the sliding frame 361, a gear transmission structure B363 is installed at the output end of the servo motor C362, and a gear B364 meshing with the gear belt B35 is installed on the gear transmission structure B363.

[0049] Specifically, the gear transmission structure B363 is composed of two gears D and an internal toothed belt B meshing with the two gears. The two gears D are respectively connected and fixed to the gear B364 and the output end of the servo motor C362. The servo motor C362 is started to drive the gear transmission structure B363 to operate, and indirectly drive the gear B364 to rotate on the gear belt B35, so that the laser cutting head 5 moves to the upper specified position on the laser cutting head moving auxiliary mechanism 3, so that the laser cutting head 5 can be flexibly moved to the specified position on the X-axis.

[0050] When using this application,

[0051] Start the servo motor A411 to drive any conveyor rack 42 to move under the laser cutting head 5. Place the plate to be cut on the conveyor rack 42 that has not moved directly under the laser cutting head 5 and wait for the next round of cutting. After the plate on the previous conveyor rack 42 is cut, start the servo motor A411 immediately to move the next conveyor rack 42 to directly under the laser cutting head 5 for laser cutting, and put the new plate to be processed on the previous conveyor rack 42. This design makes it easy to achieve the continuity of cutting by the laser cutting machine and improve the working efficiency of the laser cutting machine.
