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-width multifunctional laser machine. The cutting and splicing method of a wide-width multifunctional laser machine of the present invention comprises the following steps: a. dividing a CAD pattern according to the working range of a single laser head; b. Calculate the number of sub-graphic blocks divided by the CAD pattern on the X-axis as d, the X-axis of the CAD pattern is parallel to the length direction of the cloth, set the working length of the laser head on the X-axis as a; c, calculate the laser head on the X-axis The working range in the direction Lm=d*a; d, calculate the difference between the working range of the laser head and the length Lx of the CAD image on the X axis s=Lm‑Lx; e, determine the length of the laser head moving at the seam as Lr=a-s. The cutting and splicing method of the present invention can reduce seam predictions during cyclic printing of CAD patterns, and improve the utilization rate of cloth.
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...
