In this embodiment, it is preferred that the front end of the air blowing is arranged with uniform air blowing holes. Through this structure, a complete air blowing air curtain can be formed. The width of the air blowing of the utility model is greater than the maximum processable range of the field mirror, ensuring the air blowing effect. The rear section of the air outlet is connected to the air pipe to the precision pressure regulating valve through a joint. In order to ensure good processing efficiency and dust removal effect, the air blowing pressure is generally not greater than 0.1Mpa.

Since the arrangement of the photosensitive units is one-dimensional, each exposure is only a line on the cut product. The image is formed into a line image, and with the relative movement between the cut product and the scanning camera 161, continuous exposure is achieved, and finally a two-dimensional image is formed. The transparent bottom plate 163 is installed on the frame and is set at the lower end of the cut product to support and flatten the cut product.

[0076] In step S22, process parameters of each layer are set.

[0077] Specifically, after the layer processing module completes the analysis, the processing parameter module is used to set the process parameters of each layer. Specifically set the scanning speed, laser power, and number of cuts for each layer. For the above-mentioned workpiece, the scanning speed, laser power, and number of cuts are set in sequence. Preferably, the parameter setting of the copper foil penetration layer is that the scanning speed is set to A, the 20w60w laser power is set to 95%, and the number of cuts is set to n times; the parameter setting of the second film penetration layer is that the scanning speed is set to A, the 20w60w laser power is set to 95%, and the number of cuts is set to n+2 times; further, the third film penetration layer is that the scanning speed is set to A, the 20w60w laser power is set to 95%, and the number of cuts is n times, and the filling module is used to fill the fine holes. The filling pattern of the filling module can be set to a circular ring "◎", "X" shape, etc. Preferably, in this embodiment, it is set to an array circular ring "◎", and the array spacing is 0.1mm. After using the filling function, the fine holes can be gasified during the cutting process, which is convenient for waste discharge. After the processing parameters are set, the drawing area allocation module is used to partition the drawing.

[0078] In step S23, the processing drawing is partitioned, and the partition ranges of the partitioned processing drawing corresponding to each galvanometer component are calculated and initialized, and then the corresponding theoretical processing time is calculated.

[0079] Specifically, the drawing partition is initialized, and the drawing area allocation module calculates the theoretical processing time of the initial partition range of the first galvanometer component 25, the initial partition range of the second galvanometer component 26, the initial partition range of the third galvanometer component 27, and the initial partition range of the fourth galvanometer component 28 respectively;

[0080] Further, the processing time error range of the image area allocation module is set. Preferably, in this embodiment, the parameter value is set to 5%; the image area allocation module is further used to automatically increase or decrease the processing partition ranges of the first galvanometer assembly 25, the second galvanometer assembly 26, the third galvanometer assembly 27, and the fourth galvanometer assembly 28;

[0081] Preferably, in this embodiment, after calculation, the processing partition range of the first galvanometer component 25 is 1.1, 1.2....1.5, 2.1; the processing partition range of the second galvanometer component 26 is 2.2...2.5; 3.1, 3.2; the processing partition range of the third galvanometer component 27 is 3.3...3.5, 4.1, 4.2; the processing partition range of the fourth galvanometer component 28 is 4.3, 4.4, 4.5; the calculated theoretical processing time difference is less than 5%, and the optimized area allocation can reduce the galvanometer downtime and greatly improve the overall processing efficiency of the equipment.

[0082] In one embodiment, when step S12 is executed, the traction guide positioning component and the deviation correction component of the equipment are set to be turned on, and the product to be processed is pulled to the specified position through the active roller component. In the utility model, the active roller component and the traction guide positioning component form a tension point to achieve tension and straightening of the workpiece to be processed; the deviation correction component is set between the active roller component and the traction guide positioning component to control the deviation of the workpiece to be processed within 0.5°. Subsequently, adsorption and dust removal are turned on, and the workpiece to be processed is flatly adsorbed to the vacuum adsorption component; synchronously, the XYZ axis returns to zero with one key, and the galvanometer controls the laser to complete the cutting through the linkage of the XYZ axis; after the cutting is completed, the vacuum adsorption component is turned off, and the active roller component collects the processed product to the coil area, and the single piece processing is completed; adsorption and dust removal are turned on again, and the above steps are repeated to start the next stage of product processing.

Since the present disclosure can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
