Here’s how it works:

As shown in Figure 1, the processing material 8 is manually inserted into the cutting machine guard 2 from the inlet and outlet window 5 on the left, and passes between the two rollers inside the upper end of the left feeding mechanism 7, and continues to the right. The side passes between the laser processing table 6 and the four laser processing units 9, then passes between the two rollers inside the upper end of the right feeding mechanism 7, and passes through the right inlet and outlet window 5 to the cutting The outside of the machine guard 2 is wound around the winding end, and the equipment is turned on for trial operation and debugging, so that the processing material 8 can be stably processed inside the cutting machine guard 2, and then normal processing is started;

As shown in Figures 2 to 4, the four laser processing units 9 provided inside the cutting machine guard 2 can move forward and backward and left and right above the laser processing table 6 through the front and rear displacement mechanism 10 and the left and right displacement mechanism 11, so that the laser The upper end of the processing table 6 forms four processing areas, which are the first area, the second area, the third area and the fourth area from right to left. When the processing work material 8 is processed from left to right at the upper end of the laser processing platform 6 , can carry out partitioned processing in four different processing areas through four laser processing units 9, and the four laser processing units 9 can process at the same time or separately, making the processing more flexible and efficient;

As shown in Figure 4, the processing work material 8 is clamped and positioned on the upper end of the laser processing table 6 through the feeding mechanisms 7 at both ends, so that the processing work material 8 can be laid flatly on the upper end of the laser processing table 6. Since the processing work material 8 is designed according to the Material feeding is at a fixed value, so when the feeding of the processing work material 8 stops, the upper end of the laser processing table 6 will vacuum the processing work material 8 and fix the position of the processing work material 8. At this time, the four laser processing units 9 pass through the corresponding four A visual positioning mechanism 16 is used to grasp and position the target, and then the focusing mechanism 15 is used to adjust the position of the focus of the laser emitted from the lower end of the laser processing head 14 to ensure that the laser focus acts on the material surface and ensure the effect of the laser process. After adjusting the laser focus, The laser source generator 12 provides a laser light source to the galvanometer mechanism 13 and the laser processing head 14, and starts processing the work material 8 through the laser, thereby processing the workpiece;

In addition, during the processing, the feeding of the processing work material 8 needs to cooperate with the processing of the four laser processing units 9. In order to improve the matching accuracy and production efficiency of the processing work material 8 and the four laser processing units 9, it is necessary to ensure the processing While improving efficiency, it is necessary to control and set the progress and frequency of processing the work material 8 to form a processing cycle, and realize the processing of the workpiece through the cycle of the processing cycle. Let the length of the workpiece be G, and let the length of the laser processing table 6 be L. , assuming that the number of times of processing work material 8 in one processing cycle is C, assuming the number of workpieces produced in one processing cycle is S, and assuming the length of processing 8 materials being processed is D;

when When,/> ,/> ,/> ,/> G, before the last material feeding, the four laser processing units 9 perform corresponding processing according to the number of feedings of the work material 8 in one processing cycle, and the four laser processing units 9 process at the same time. During the last material feeding, Let the corresponding laser processing unit 9 process according to the processing area covered by the tail of the workpiece to complete a processing cycle;

when When,/> 1,/> ,/> G, let the corresponding laser processing unit 9 process according to the processing area covered by a workpiece to complete a processing cycle;

when When,/> 1,/> ,/> G, let the corresponding laser processing unit 9 process according to the processing area covered by the two workpieces to complete a processing cycle;

By analogy, when When,/> 1,/> ,/> G, let the corresponding laser processing unit 9 process according to the processing area covered by the two workpieces to complete a processing cycle;

As shown in Figures 5 to 8, flue gas with dust particles will be generated during the processing. The negative pressure dust extraction connector 23 generates negative pressure inside the dust collection pipe 20 through the dust extraction pipe, and pumps it to the dust collection pipe 20 through the dust extraction port 21. Internal suction, the flue gas with dust particles is sucked into the dust extraction pipe for processing to avoid contamination of the product and the lower end of the laser processing head 14. At the same time, there are multiple positive pressure airflow nozzles 19 located on the lower sides of the left and right ends of the dust extraction mechanism 17 The air will be blown upward, and the air will be sucked through the processing window 18 as a channel and the dust extraction port 21 to form a surrounding air flow dust extraction hood, which will block the smoke and dust within the scope of the dust extraction hood and prevent diffusion, which can effectively remove the smoke and dust generated by the processing. After production, since the dust extraction mechanism 17 is composed of a connecting seat at the upper end and a fixed seat at the lower end, it can be disassembled and cleaned, and the dust extraction mechanism 17 should be cleaned and maintained regularly to prevent smoke from accumulating inside the dust extraction mechanism 17 .
