Problems solved by technology
That is, the laser head can process a certain format without moving. However, due to the limitation of precision, the maximum processing range of a single laser head of domestic and foreign laser marking and cutting machines is 600mm*600mm. This makes it difficult to process some large-format patterns, and the laser head with a larger processing range has higher requirements for precision and higher cost
[0004] When processing a long cloth, the CAD pattern is usually processed on the cloth in a cycle. Since the working range of the laser head is square, when the length of the CAD pattern is not an integer multiple of the working length of the galvanometer marking head, the two There will be seam residue at the junction of CAD drawings, resulting in waste of fabric

Embodiment 2
[0037] The main difference between this embodiment and the first embodiment is that there are multiple laser heads on the crossbeam. For the convenience of understanding and description, this embodiment sets four laser heads, and the four laser heads are sequentially numbered as No. 1. No. 2, No. 3 and No. 4, the main difference between its cutting method and embodiment one is that in step e, since there are four laser heads, the control system sends corresponding sub-graphic blocks to each laser head respectively, as in processing In the first row, send the name (X) to the No. 1 laser head 1 , Y 1 ) sub-graphic block, and send it to laser head No. 2 named (X 2 , Y 1 ) sub-graphic block, and send it to laser head No. 3 named (X 3 , Y 1 ) sub-graphic block, and send it to laser head No. 4 named (X 4 , Y 1 ), each laser head prints and runs independently, and prints the content of the corresponding sub-graphic block. When all the laser heads print the corresponding graphic...

The invention discloses a cutting and splicing method of a wide range multifunctional laser machine. The cutting and splicing method of the wide range multifunctional laser machine comprises the following steps that a, a CAD pattern is divided according to the working range of a single laser head; b, the number of the divided sub-pattern blocks of the CAD pattern on X-axis is calculated, wherein the number of the sub-pattern blocks is d, the X-axis of the CAD pattern is parallel to the length direction of a cloth, and the working length of the laser head on the X-axis is set to be a; c, the working range Lm=d*a of the laser head in the X-axis direction is calculated; d, and the difference value s=Lm-Lx between the working range of the laser head and the length Lx of the CAD pattern on theX-axis; e, the length that Lr=a-s of the movement of the laser head when a seam is jointed is determined. According to the cutting and splicing method, a residual material is reduced when the CAD pattern is printed in a circulating mode, the utilization rate of the cloth is improved.
Description
technical field [0001] The invention relates to the field of laser machining, in particular to a cutting and splicing method for a wide-width multifunctional laser machine. Background technique [0002] At present, there are basically two types of blanking in the toy and clothing industry. One is forming knife blanking. The forming knife blanking efficiency is relatively high. One shape requires one kind of cutting tool. The forming knife has a long production cycle and high cost; the second is laser cutting. For blanking, laser blanking is a single laser beam blanking, which requires two motors on the X-axis and Y-axis to drive the laser beam out of the shape of the layout, and the speed cannot be too fast. [0003] The current laser processing equipment usually includes at least one set of laser head, X-axis driving device and Y-axis driving device. The laser head is a galvanometer scanning marking head, which is mainly composed of XY scanning mirror, field mirror, Comput...
