[0048] Through the design of the dual-axis motor 202, the lifting plate 203, the first bevel gear 204, the second bevel gear 205, the threaded rod 206 and the fastening block 207, when it is necessary to lift the metal plate on the upper surface of the lifting plate 203, the computer 3 can control the dual-axis motor 202 to drive the first bevel gear 204 on both sides of the output shaft to rotate, so that the first bevel gear 204 can drive the second bevel gear 205 to rotate, and the second bevel gear 205 will drive the threaded rod 206 to rotate, so that the threaded rod 206 can drive the outer surface fastening block 207 to rise and fall, and then the fastening block 207 can drive the lifting plate 203 to rise and fall vertically, so that the lifting plate 203 can drive the metal plate placed on the upper surface to rise and fall, so as to assist the staff in carrying the metal plate, which can reduce manual participation, reduce labor intensity, and improve transportation efficiency.

[0049] This embodiment also provides a laser cutting method, which uses the above-mentioned laser cutting platform to cut the metal plate, and specifically includes the following steps:

[0050] S1. Place the metal plate:

[0051] The worker places the metal plate to be cut on the upper surface of the lifting mechanism 2, i.e., the lifting plate 203;

[0052] S2. Lifting metal plate:

[0053] The computer 3 controls the dual-axis motor 202 to start, driving the first bevel gear 204 to rotate, and then the threaded rod 206 to rotate through the second bevel gear 205;

[0054] The rotation of the threaded rod 206 drives the fastening block 207 to rise, thereby driving the lifting plate 203 to rise vertically until the lifting plate 203 is flush with the cutting table 107;

[0055] S3. Metal plate clamping and movement:

[0056] The first reduction motor 108 is started, driving the connecting rod 103 to flip 90 degrees, so that the centering dragging and dropping mechanism 4 (including the second reduction motor 401, the rotating rod 402, the guide block 405, the connecting arm 410, the hydraulic rod 406, the pushing plate 407 and the anti-slip clamping plate 408) faces the lifting plate 203;

[0057] The first linear module 101 is started, driving the two sets of connecting plates 102 and the centering dragging and dropping mechanism 4 thereon to move to the top of the lifting plate 203;

[0058] The second reduction motor 401 is started to drive the rotating rod 402 to rotate, and the positive thread 404 and the negative thread 403 synchronously drive the guide block 405 to move toward the center, so that the anti-slip clamping plate 408 is clamped on both sides of the metal plate;

[0059] The first linear module 101 is started again to move the clamped metal plate to the upper surface of the cutting table 107 and within the central monitoring range of the camera 5;

[0060] S4, Laser Cutting:

[0061] The first reduction motor 108 is started again to rotate the laser cutter 106 to be flush with the metal plate;

[0062] The camera 5 detects the edge of the metal plate using an image processing algorithm (such as the Canny algorithm) and virtually draws a cutting frame in the monitoring screen to indicate the cutting position and range of the laser cutter 106;

[0063] The computer 3 is linked with the first linear module 101 and the second linear module 109 to control the laser cutter 106 to perform precise cutting according to the cutting frame information;

[0064] During the cutting process, the camera 5 continuously performs image recognition and analysis on the monitoring screen, timely adjusts the position and size of the cutting frame, and monitors the working status and cutting results of the laser cutter 106;

[0065] S5. Cutting completion and stacking:

[0066] After the cutting is completed, the first reduction motor 108 is started again to rotate the centering dragging and dropping mechanism 4 to be flush with the cutting table 107;

[0067] The center dragging and dropping mechanism 4 clamps the cut metal plate and moves it to the upper surface of the lifting plate 203 through the first linear module 101;

[0068] Each time a group of metal plates are stacked, the computer 3 controls the dual-axis motor 202 to drive the threaded rod 206 to drive the lifting plate 203 to descend to a certain height;

[0069] During the stacking process, the hydraulic rod 406 can be activated to make the push plate 407 drive the anti-slip clamping plate 408 to rise to a certain height to avoid friction or collision between the metal plates during stacking;

[0070] S6. Transferring stacked metal plates:

[0071] When all the cut and stacked metal plates are stacked on the lifting plate 203, the lifting plate 203 is lowered to the lowest position for the staff to transfer.

[0072] Through the above series of steps, the laser cutting platform realizes the automatic lifting, clamping, precise cutting and stacking of metal plates, greatly reducing manual intervention and improving production efficiency and safety.

[0073] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when cutting the metal plate, the staff can place the metal plate on the upper surface of the lifting plate 203, and then the computer 3 can control the dual-axis motor 202 to drive the first bevel gear 204 on both sides of the output shaft to rotate, so that the first bevel gear 204 can drive the second bevel gear 205 to rotate, and the second bevel gear 205 will drive the threaded rod 206 to rotate, so that the threaded rod 206 can drive the outer surface fastening block 207 to rise and fall, and then the fastening block 207 can drive the lifting plate 203 to rise vertically, so that the lifting plate 203 can rise to be flush with the cutting table 107, and then the first reduction motor can be started. 108 drives the connecting rod 103 to flip 90 degrees, so that the connecting rod 103 can drive the guide block 405 and the connecting arm 410 in the rotating groove 110 to flip 90 degrees, and then the first linear module 101 can be started to drive the two groups of connecting plates 102 to move to the top of the lifting plate 203, so that the two groups of connecting arms 410 in the connecting rod 103 of the connecting plate 102 can be moved to the two ends of the metal plate, and then the second reduction motor 401 can be started to drive the rotating rod 402 to rotate in the rotating groove 110, and the rotating rod 402 will drive the two groups of guide blocks 405 installed on the outer surface of the positive thread 404 and the reverse thread 403 to synchronously move to the center, so that the two groups of guide blocks 405 can drive the two groups The anti-skid clamps 408 slidably installed in the connecting arm 410 are clamped on both sides of the metal plate, and then the first linear module 101 can be started again to move the metal plate clamped in the anti-skid clamps 408 to the upper surface of the cutting table 107 and within the central monitoring range of the camera 5. Then, the first reduction motor 108 can be started again to rotate the laser cutter 106 to be flush with the metal plate, and the camera 5 can use the image processing algorithm to analyze and measure the marked graphics or contours to determine the position, size and shape of each part to be cut, and then draw the boundary box of these parts to be cut, i.e., the cutting box, in a virtual way in the monitoring screen of the camera 5 to indicate the cutting position and range of the laser cutter 106. , and through the linkage control of the computer 3 and the first linear module 101 and the second linear module 109, the cutting position and range information recognized by the visual system of the camera 5 can be transmitted to the computer 3, so that the computer 3 can control the first linear module 101 and the second linear module 109 to control the laser cutter 106 in real time to accurately cut the metal plate. In the cutting process, the camera 5 will continue to perform image recognition and analysis on the monitoring screen, adjust the position and size of the cutting frame in time, and obtain the real-time working status and cutting results from the laser cutter 106, so as to realize real-time control and feedback of the cutting process. After the cutting is completed, the first reduction motor 108 can be started again to rotate the connecting arm 410 to be flush with the cutting table 107.Then, the connecting arm 410 can drive the anti-skid clamping plate 408 to clamp the two sides of the cut metal plate, and then the cut metal plate can be placed on the upper surface of the lifting plate 203 through the first linear module 101. When a group of metal plates are stacked on the upper surface of the lifting plate 203, the computer 3 controls the dual-axis motor 202 to drive the threaded rod 206 to drive the lifting plate 203 to descend to a certain height. In the process of stacking the metal plates, the hydraulic rod 406 can be started to pull the push plate 407 at one end of the piston rod to rise, so that the push plate 407 can drive the anti-skid clamping plate 408 to rise, and then the metal plate clamped by the anti-skid clamping plate 408 can be lifted to a certain height, which can avoid unnecessary friction or collision between the metal plates during the stacking process and cause the stacked metal plates to deflect, and can ensure the stability and safety of the stacking. Then, the lifting plate 203 can be lowered to the lowest point for the staff to transport it.

[0074] In summary: This laser cutting platform significantly improves the accuracy, efficiency and safety of laser cutting of metal plates by integrating automated handling, precise cutting, intelligent stacking and real-time monitoring functions.
