Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more particularly to a laser cutting mobile platform. Background Technology

[0002] Laser cutting, with its advantages of high precision, high speed, and strong adaptability, has become a core process in sheet metal processing and is widely used in hardware manufacturing, steel structure processing, and precision parts production. As the core load-bearing and processing mechanism of sheet metal cutting equipment, the laser cutting mobile platform's structural rationality, adjustment flexibility, and cleaning and dust removal capabilities directly determine the precision and quality of the sheet metal cutting. Currently, conventional laser cutting mobile platforms on the market have relatively simple structures, mostly using fixed support tables and fixed cutting stations. They can only achieve basic planar cutting operations, have poor height adjustment precision, and cannot adapt to the processing needs of sheet metal sheets of different thicknesses and specifications, resulting in poor versatility. Furthermore, the cutting support structure of traditional platforms is mostly a fixed, integral design, which easily leads to interference between the laser cutting head and the support structure during operation. This not only causes wear on the support structure but also results in burrs, gaps, and other defects on the cut edges of the sheet metal, severely affecting cutting precision.

[0003] Therefore, it is necessary to design a laser cutting mobile platform that can protect the support structure. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a laser cutting mobile platform.

A drive assembly is located on the rear side of the top of the right fixed platform, and the drive assembly is connected to the right end of the adjacent rotating rod. Synchronous pulleys are located at the ends of the rotating rods on the U-shaped frames, and a synchronous belt is wound between two adjacent synchronous pulleys. Each platform is equipped with a first transverse slide rail. A sliding frame is slidably mounted between the first transverse slide rails on the same side. A rectangular hole is opened in the middle of the front and rear sides of the sliding frame. The lower side of the synchronous pulley passes through the rectangular hole in the lower part of the sliding frame.

[0009] Furthermore, the pressing mechanism includes a second transverse slide rail, a transverse slider, a second vertical slide rail, a second vertical slider, a crossbar, a second electric push rod, a second connecting block, and a pressure frame.

An air pump is set on the rear side wall of the second vertical slide rail, and an air blowing nozzle is set on the right side wall of the first vertical slide rail. An air pipe is loosely wound on the horizontal column, with sufficient extension allowance. One end of the air pipe is fixedly connected to the air blowing nozzle, and the other end is fixedly connected to the air outlet of the air pump, so that it will not be pulled or tangled during movement.

[0011] Furthermore, it also includes a control panel, which is located on the rear left side of the frame. The control panel has a built-in controller, which is connected to the servo motor, electric slide rail, laser cutter, first electric push rod, second electric push rod and air pump via wiring.

[0012] The beneficial effects of this invention are: 1. During the cutting operation of this equipment, only the toothed frame corresponding to the laser cutting point can be precisely moved down to make way through pressing and squeezing and elastic compression.

[0013] 2. The air nozzle can move synchronously with the cutting point in real time to accurately blow away residual metal chips and dust in the cutting area, avoiding chip accumulation that could scratch the sheet metal and reduce cutting accuracy; at the same time, fallen impurities can be collected in the collection box, and the negative pressure adsorption function of the suction port can achieve centralized cleaning of chips and dust, effectively preventing dust from scattering and purifying the working environment.

A sliding frame 76 is slidably arranged between the first transverse slide rails 75 on the same side. A rectangular hole is opened in the middle of the front and rear sides of the sliding frame 76. The lower side of the synchronous wheel 77 passes through the rectangular hole in the lower part of the sliding frame 76. The upper part of the synchronous wheel 77 is fixedly connected to the sliding frame 76. An electric slide rail 79 is provided on the top of the sliding frame 76. An electric slider 710 is slidably arranged on the electric slide rail 79. A first vertical slide rail 711 is provided on the top of the electric slider 710. A first vertical slider 712 is slidably arranged on the first vertical slide rail 711. A laser cutter 713 is arranged on the first vertical slider 712. A first electric push rod 714 is provided on the top of the first vertical slide rail 711. The push rod of the first electric push rod 714 is connected to the top of the first vertical slider 712.

[0024] like Figure 1 , Figure 3 and Figure 6 As shown, the pressing mechanism 8 includes a second transverse slide rail 81, a transverse slider 82, a second vertical slide rail 83, a second vertical slider 84, a crossbar 85, a second electric push rod 86, a second connecting block 87, and a pressing frame 88. The second transverse slide rail 81 is mounted on the top of the frame 1. The transverse slider 82 is slidably mounted inside the second transverse slide rail 81. The second vertical slide rail 83 is mounted on the transverse slider 82. The second vertical slider 84 is slidably mounted inside the second vertical slide rail 83. A crossbar 85 is mounted between the two second vertical slide rails 83. The crossbar 85 is connected to the electric slider 710.

The pressing frame 88 is in contact with the arc-shaped block 57.

[0025] like Figure 1 and Figure 6As shown, the air blowing mechanism 9 includes a third connecting block 91, a horizontal column 92, an air pump 93, an air pipe 94, and an air blowing nozzle 95. The third connecting block 91 is provided on the top of the second vertical slide rail 83, and the horizontal column 92 is provided between the two third connecting blocks 91. The air pump 93 is provided on the rear side wall of the second vertical slide rail 83, and the air blowing nozzle 95 is provided on the right side wall of the first vertical slide rail 711. The air pipe 94 is wound around the horizontal column 92. One end of the air pipe 94 is connected to the air blowing nozzle 95, and the other end of the air pipe 94 is connected to the air outlet of the air pump 93.

[0026] like Figure 1 As shown, it also includes a control panel 10. Control panels 10 are provided on the left rear side of the frame 1. The control panel 10 has a built-in controller. The controller is connected to the servo motor 26, electric slide rail 79, laser cutter 713, first electric push rod 714, second electric push rod 86 and air pump 93 through the line.

[0027] Workers place the sheet metal to be processed stably on the placement rack 54 of the movable placement platform 5. Multiple sets of placement racks 54 form a uniform support surface, ensuring that the sheet metal is placed flat and the force is evenly distributed. The overall processing height is pre-adjusted according to the thickness of the sheet metal to be processed and the cutting process requirements: control commands are issued through the control panel 10 on the left side of the frame 1, and the built-in controller of the equipment starts the servo motor 26. The output shaft of the servo motor 26 drives the corresponding transmission wheel 28 to rotate. Power is transmitted through two sets of meshing transmission wheels 28, which, together with the pulley 24 at the bottom of the lead screw 22 and the flat belt wound between the four pulleys 24, synchronously drive the four sets of vertical lead screws 22 of the frame 1 to rotate synchronously. During the rotation of the lead screw 22, the nut 23 screwed on the lead screw 22 moves vertically in a straight line. The nut 23 drives the collection frame 3, the rectangular frame 4 and the entire movable placement platform 5 to rise and fall synchronously through the second fixing block 27 at the top, accurately adjusting the relative processing height between the sheet metal and the laser cutting machine 713 to adapt to the cutting requirements of sheet metal of different thicknesses.

[0028] After the sheet height is adjusted, the equipment enters the cutting process. The operator starts the cutting program through the control panel 10, and the moving cutting component 7 begins the full-range adjustment operation: the drive component 74 on the top of the right fixed platform 71 operates, driving the corresponding rotating rod 73 to rotate forward and backward. The synchronous wheel 77 at the end of the rotating rod 73 rotates accordingly. Through the closed-loop transmission of the synchronous belt 78, it drives the sliding frame 76 to slide back and forth along the first transverse slide rail 75 on the top of the fixed platform 71, realizing the coarse adjustment of the laser cutting machine 713 in the front and back positions. At the same time, the electric slide rail 79 on the top of the sliding frame 76 can drive the electric slider 710 to slide left and right, completing the precise fine adjustment of the laser cutting machine 713 in the left and right positions. With the first vertical slide rail 711 and the first electric push rod 714, the extension and retraction of the first electric push rod 714 can drive the first vertical slider 712 to rise and fall vertically along the first vertical slide rail 711, precisely adjusting the cutting height of the laser cutting machine 713, adapting to the cutting points of the sheet in all directions, and ensuring cutting accuracy.

[0029] While the electric slider 710 moves laterally for adjustment, it simultaneously drives the connected horizontal bar 85, the second vertical slide rail 83, and the bottom horizontal slider 82. This causes the horizontal slider 82 to move synchronously along the second horizontal slide rail 81 at the top of the frame 1 with the laser cutting machine 713, achieving real-time synchronous tracking between the pressing mechanism 8 and the laser cutting point. When the laser cutting machine 713 moves above the point to be cut, the corresponding second electric push rod 86 extends, driving the second connecting block 87 and the bottom pressure frame 88 to move downwards. The bottom contact surface of the pressure frame 88 presses against the arc-shaped block 57 at the top of the corresponding toothed frame 54. After being subjected to force, the arc-shaped block 57 drives the first connecting block 56 and the sliding column 53 to slide downwards along the inner side of the L-shaped block 52, compressing the elastic element 55 between the sliding column 53 and the L-shaped block 52. This causes the toothed frame 54 at that point to move downwards synchronously, temporarily separating from the sheet metal above and creating clearance space. At this point, only the placement rack 54 at the cutting point moves down to make room, while the remaining placement racks 54 around it remain in their original positions, continuously providing stable support for the sheet metal. This completely avoids interference between the laser cutting machine 713 and the support structure during the cutting operation, preventing rack wear or sheet metal cutting defects, and also ensures that the sheet metal as a whole does not sway or wobble, guaranteeing cutting accuracy. When the laser cutting machine 713 completes the cutting at this point and moves to the next processing position, the pressure frame 88 moves synchronously with the second vertical slide rail 83, disengaging from the currently repositioned arc block 57. The compressed elastic element 55 releases its elasticity, pushing the sliding column 53, placement rack 54, and arc block 57 to automatically reset, restoring support for the sheet metal, and completing the full-area sheet metal cutting operation in a cyclical manner.

[0030] After the cutting operation is completed, a cleaning process is initiated to remove dust from the equipment platform. The air blowing mechanism 9 moves synchronously with the cutting components to keep the cleaning point consistent with the cutting operation point: the air pump 93 on the second vertical slide rail 83 at the rear of the frame 1 is started, and the generated high-pressure airflow is delivered through the air pipe 94 to the air blowing nozzle 95 on the side wall of the first vertical slide rail 711. The high-pressure gas is precisely sprayed onto the toothed frame 54 and the plate processing surface, thoroughly blowing off the metal chips, dust and other impurities remaining from the cutting, avoiding the accumulation of chips that would affect the accuracy of subsequent cutting operations.

[0031] Meanwhile, the suction port 6 connected to the lower part of the rectangular frame 4 can be connected to an external suction device. The debris that falls off when the air is blown out will fall into the collection frame 3 below. Through the negative pressure adsorption effect of the suction port 6, the cutting debris and dust accumulated in the collection frame 3 can be uniformly sucked and collected in real time, realizing centralized cleaning of debris and avoiding debris from scattering and polluting the equipment and working environment.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
