[0020] (1) In the present invention, two conveying assemblies are used to convey the plates to be cut, so that the device can realize the automatic loading function, thereby reducing the workload of the staff in lifting and loading the plates, thereby making the use of the device more labor-saving.

By using the first motor to drive and rotate the bidirectional lead screw, the two conveying assemblies are driven by the moving block installed at the bottom to move toward or relative to each other. By moving the two conveying assemblies, the distance between the two conveying assemblies is adjusted, so that the two conveying assemblies can convey plates of different widths, thereby enabling the device to cut plates of different models, thereby improving the cutting processing efficiency of the device. The range of the machine is determined by setting a blocking component.

In particular, under the detection of the laser sensor, the blocking component can intercept the plate to be cut conveyed by the conveying component more timely, so that the equipment can intercept the plate to be cut more accurately, and the second hydraulic cylinder can retract the baffle, so that the equipment can directly release the plate that does not need to be cut or has been cut, so that the operator can selectively cut the plate, thereby making the cutting process of the equipment more flexible.
[0021] (2) In the present invention, the plate to be cut is lifted by using a lifting plate. On the one hand, it plays a supporting role for the plate to be cut, so that the plate to be cut can be more stable during processing, so that the plate will not be skewed when the device cuts the plate, thereby improving the accuracy of the laser cutting of the plate by the device. On the other hand, the plate to be cut is directly lifted by the lifting plate, and is removed from the conveying component. This method of removing the plate makes the structure of the device simpler, occupies less space, and removes the plate from the conveying component faster, thereby making the efficiency of the laser cutting of the plate by the device higher. By using the first hydraulic cylinder to drive, the clamping plate clamps the plate from both sides of the plate to fix the plate, making the plate more stable during the laser cutting process, thereby further improving the accuracy of the laser cutting of the device.

[0049] When in use, first, place the plate to be cut on the conveyor belts 204 of the two conveyor components 2, and drive the second motor 203 to rotate the second pulley 202, and drive the conveyor belt 204 to convey by rotating the second pulley 202, and convey the plate to the jacking component 5 through the two conveyor belts 204, and drive the second hydraulic rod 403 to move through the second hydraulic cylinder 402, and the second hydraulic rod 403 drives the baffle 405 to move up and down through the top plate 404, and moves the baffle 405 upward, and blocks the plates on the two conveyor belts 204 through the baffle 405. By using two conveyor components 2 to transport the plates to be cut, the equipment realizes the automatic loading function, thereby reducing the workload of the staff in lifting and loading. The load is thereby reduced in manpower when used in the equipment, and at the same time, it is ensured that the staff will not be exposed to the processing area of the equipment, and the staff will not be harmed by the laser, thereby making the use of the equipment safer. By using the first motor 105 to drive and rotate the bidirectional lead screw 102, the two conveying assemblies 2 are driven by the shift block 3 installed at the bottom to move toward or relative to each other by rotating the bidirectional lead screw 102. By moving the two conveying assemblies 2, the distance between the two conveying assemblies 2 is adjusted, so that the two conveying assemblies 2 can convey plates of different widths, thereby enabling the equipment to cut plates of different models, thereby improving the cutting processing range of the equipment. By setting the blocking assembly 4, the baffle 405 on the blocking assembly 4 is placed on the second hydraulic cylinder 40 2, it moves upward to block the plate on the conveying component 2, so that the plate to be processed can be stably intercepted in the processing area, realizing the positioning function of the plate to be cut, thereby making the cutting process of the equipment more convenient and more accurate, thereby effectively improving the cutting accuracy of the equipment. In particular, under the detection of the laser sensor, the blocking component 4 can intercept the plate to be cut transmitted by the conveying component 2 more timely, so that the device can intercept the plate to be cut more accurately, and the second hydraulic cylinder 402 can retract the baffle 405, so that the device can directly release the plate that does not need to be cut or has been cut, so that the operator can selectively cut the plate, thereby making the cutting process of the equipment more flexible, and then The third hydraulic cylinder 505 drives the third hydraulic rod 506 to move, and the third hydraulic rod 506 drives the lifting plate 503 to move up and down, and lifts the lifting plate 503 upward. The lifting plate 503 lifts the plates on the two conveyor belts 204, and the first hydraulic cylinder 205 on the two conveyor racks 201 drives the first hydraulic rod 206 to move. The first hydraulic rod 206 pushes the clamping plate 207 to move, and the plates lifted by the lifting plate 503 are clamped by the clamping plates 207 on the two conveyor racks 201. By using the lifting plate 503 to lift the plates to be cut, on the one hand, it plays a supporting role in making the plates to be cut more stable during processing, so that the plates will not be skewed when the equipment cuts the plates.Thereby improving the accuracy of the laser cutting of the plate of the device. On the other hand, the plate to be cut is removed from the conveying component 2 by directly lifting the plate through the lifting plate 503. This method of removing the plate makes the structure of the device simpler and occupies less space. The plate is removed from the conveying component 2 at a faster speed, thereby making the efficiency of the laser cutting processing of the plate of the device higher. By using the first hydraulic cylinder 205 to drive the clamping plate 207 to clamp the plate from both sides of the plate, the plate is fixed, making the plate more stable during the laser cutting process, thereby further improving the accuracy of the laser cutting of the device. Finally, through the The third motor 606 drives the first gear 605 to rotate, and the first gear 605 drives the left and right movable seat 603 to move left and right by meshing with the first tooth plate 602. The fourth motor 703 drives the screw rod 702 to rotate, and the screw rod 702 is rotated to move the nut 706. The nut 706 drives the front and rear movable plate 704 to move back and forth. The position of the laser head 10 is adjusted by the left and right movable seat 603 and the front and rear movable plate 704, so that the laser head 10 is located on the plate. The fifth motor 902 drives the second gear 903 to rotate, and the second gear 903 is meshed with the second tooth plate 906 to drive the lifting rod 904 to move up and down. Move the lifting rod 904 downward to adjust the distance between the laser head 10 and the plate. After adjusting the position of the laser head 10, turn on the laser head 10. According to the cutting requirements, the laser displacement sensor and the laser distance sensor are used to detect the position of the laser head 10 at all times, and the PLC controller is used to control the movement of the laser head 10 to perform laser cutting on the plate. During the plate cutting process, the visual sensor 11 transmits the detected visual signal to the PLC controller to intelligently adjust the laser cutting process of the plate. The device can detect the position of the plate and the laser head by setting the laser sensor, the displacement sensor and the laser distance sensor. The laser head 10 is positioned, and the visual sensor 11 provides feedback of the visual signal during cutting. The PLC controller then precisely controls the movement of the laser head 10, achieving automatic cutting of the sheet metal, making the device more intelligent. The third motor 606 is used to drive the laser head 10 to the left and right, and the fourth motor 703 is used to drive the laser head 10 to the front and back. By adjusting the left and right and front and back positions of the laser head 10, the laser head 10 can cut the sheet metal along any cutting route, thereby enabling the device to meet different cutting requirements for sheet metal cutting, thereby expanding the application range of the device.
