Detailed Description
The invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the present invention provides a multi-galvanometer tiled printing system 100, wherein the multi-galvanometer tiled printing system 100 is used for workpiece forming. The multi-galvanometer spliced printing system 100 comprises a control device 10, a plurality of laser emitting devices 20 and a plurality of scanning galvanometer devices 30 respectively corresponding to the plurality of laser emitting devices 20. Each scanning galvanometer device 30 has a scanning area, and the set of the plurality of scanning areas includes an area to be printed. The control device 10 is connected to all the laser emission devices 20 and the scanning galvanometer devices 30, and is used for controlling the laser emission devices 20 to emit laser beams and controlling the scanning galvanometer devices 30 to move, so that the laser beams melt metal powder on the processing platform after passing through the scanning galvanometer devices 30 and form a printing layer of a workpiece to be formed after cooling.
An overlapping area is formed between the plurality of scanning areas, the overlapping area extends at least partially to the edge of the area to be printed, when the overlapping area is printed to an area corresponding to the overlapping area on the area to be printed in the printing process, the control device 10 controls the plurality of laser emitting devices 20 corresponding to the plurality of scanning areas related to the overlapping area to emit laser beams, after passing through the corresponding scanning galvanometer device 30, the area corresponding to the overlapping area on the area to be printed is scanned and printed along a preset path corresponding to the overlapping area, and the boundary of the preset path corresponding to the overlapping area on each printing layer randomly changes in a preset range outside the boundary of the overlapping area. Therefore, the printing boundary corresponding to the overlapping area randomly changes in each printing layer, the overlapping areas of the printing layers are not completely overlapped in the direction vertical to the workpiece, and no linear trace appears in the direction vertical to the workpiece, so that the appearance of the product is attractive, and the printing quality of the workpiece is improved.
Specifically, in one embodiment, as shown in fig. 2, the overlapping area includes a first overlapping area fbed formed by two scanning areas abed and fbcd arranged in the scanning direction, the two scanning areas abed and fbcd are respectively scanning ranges of the laser beams emitted by the two laser emitting devices 20 on the to-be-printed area after passing through the two scanning galvanometer devices 30, the first overlapping area fbed includes a first boundary e and a second boundary f arranged in the scanning direction, the first boundary e and the second boundary f intersect with the boundaries b and d of the to-be-printed area abcd, and the boundary connected between the first boundary e and the second boundary f is located on the boundaries b and d of the to-be-printed layer abcd. When the control device 10 controls the laser beam emitted by the corresponding laser emitting device 20 to scan and print each printing layer, two end points of the preset path corresponding to the same position between the first boundary e and the second boundary f on each printing layer are respectively outside the first boundary e and the second boundary f, and the distance between the end points and the corresponding first boundary e or second boundary f randomly changes within the preset range. Thus, the workpiece is free from linear marks in the direction perpendicular to the workpiece at the intersections with the first boundary and the second boundary. It will be appreciated that the boundary lines of the overlapping areas are not limited to straight lines as shown in fig. 2, but may be diagonal lines or curved lines or irregular curves.
In another embodiment, as shown in fig. 3, the area to be printed corresponds to a set of four scanning areas, and correspondingly, the multi-galvanometer stitching printing system 100 includes four scanning galvanometer devices 30 and four laser emitting devices 20 corresponding to the four scanning galvanometer devices 30, so as to complete printing of the workpiece by four laser beams. The four scan areas are ahed, fhcd, abeg, fbcg areas, respectively. The overlapping region includes, in addition to a first overlapping region fbed formed by two sets of scanning regions ahed, fhcd and abeg, fbcg arranged in the scanning direction, a second overlapping region ahcg formed by two sets of scanning regions ahed, abeg and fhcd, fbcg arranged in a direction perpendicular to the scanning direction. The second overlapping area ahcg includes a third boundary g and a fourth boundary h, which intersect with the boundaries a and c of the layer to be printed. The control device 10 controls the boundary of the scanning width corresponding to the second overlapping region in the direction perpendicular to the scanning direction to randomly vary within the preset range outside the boundary of the second overlapping region when the laser beam emitted by the corresponding laser emitting device 20 scans and prints each printing layer. In this way, the workpiece is free from linear marks in the direction perpendicular to the workpiece at the intersections with the third boundary and the fourth boundary.
In one embodiment, the scan width corresponding to the second overlap region in a direction perpendicular to the scan direction is adjusted by the number of scans of the laser beam when scanning the area corresponding to the third boundary and the fourth boundary. If the number of scans corresponding to the third boundary and the fourth boundary on one print layer is 2, the number of scans corresponding to the third boundary and the fourth boundary on the other print layer is 3. Therefore, the actual scanning width of the overlapped area on the two printing layers in the direction vertical to the workpiece is not in the same position, so that the overlapped area on the printing layers does not generate linear trace in the direction vertical to the workpiece. Further, the number of scans for printing the third boundary and the fourth boundary on the same print layer may also be different.
In another embodiment, the spot size of the laser beam for printing is adjusted by scanning the area corresponding to the third boundary and the fourth boundary when the scanning width corresponding to the second overlap area in the direction perpendicular to the scanning direction. When printing the positions corresponding to the third boundary and the fourth boundary on a printing layer, the width of the light spot of the laser beam for scanning printing in the direction perpendicular to the scanning direction is 0.1mm; when the other printing layer prints the positions corresponding to the third boundary and the fourth boundary, the width of the spot of the laser beam for scanning printing in the direction perpendicular to the scanning direction is 0.2mm. Further, the spot sizes of the laser beams used to print the third and fourth boundaries may also be different at the same print layer.
When printing the region corresponding to the overlapping region on the region to be printed, the plurality of laser beams emitted by the corresponding plurality of laser emitting devices 20 may be printed alternately in synchronization, or the plurality of laser beams emitted by the corresponding plurality of laser emitting devices 20 may be printed alternately in synchronization. As shown in fig. 4, when the control device 10 divides the overlapping area into a plurality of sub-printing areas and performs synchronous alternate printing on the overlapping area, taking the overlapping area fheg in fig. 3 as an example, the overlapping area fheg is printed on adjacent sub-printing areas of the overlapping area simultaneously in sequence by four laser beams 20a, 20b, 20c, 20d emitted by the four laser emitting devices 20 until the overlapping area is printed. When asynchronous alternate printing is performed on the overlapping area, a plurality of sub-printing areas are scanned by the laser beam 20a at intervals, and then the remaining plurality of sub-printing areas are scanned by the laser beams 20b, 20c, 20d at intervals in sequence. Further, when the overlapping areas are printed by the plurality of laser beams alternately in synchronization, the scanning directions of the plurality of laser beams may be identical or may include two opposite directions. Taking fig. 4 as an example, when the four laser beams 20a, 20b, 20c, 20d print an area corresponding to the overlapping area on the area to be printed, the scanning directions of the four laser beams 20a, 20b, 20c, 20d may all be the first direction, or the laser beams 20a, 20b may scan in the first direction, and the laser beams 20c, 20d may scan in the second direction. In one embodiment, when the overlapping areas are printed alternately by the plurality of laser beams in synchronization and the scanning directions of the plurality of laser beams coincide, the scanning direction is opposite to the direction of wind for cleaning smoke generated at the time of laser beam printing.
Referring to fig. 5, the method for printing multiple galvanometer stitching includes the following steps.
Step S1: a plurality of laser emitting devices 20 for emitting laser beams are provided.
Step S2: a plurality of scanning galvanometer devices 30 corresponding to the plurality of laser emitting devices 20 are provided, each scanning galvanometer device 30 has a scanning area, the plurality of scanning areas have overlapping areas, and a set of the plurality of scanning areas includes an area to be printed.
Step S3: the control device 10 controls the laser beams to scan and print the region corresponding to the overlapping region on the region to be printed along the preset path corresponding to the overlapping region, wherein the overlapping region at least partially extends to the edge of the region to be printed, and the boundary of the preset path corresponding to the overlapping region on each printing layer randomly changes in the preset range outside the boundary of the overlapping region.
In an embodiment, the overlapping area includes a first overlapping area formed by a plurality of scanning areas arranged in the scanning direction, the first overlapping area includes a first boundary and a second boundary arranged in the scanning direction, the first boundary and the second boundary intersect with a boundary of the area to be printed, and a boundary connected between the first boundary and the second boundary is located on a boundary of the layer to be printed. When the laser beam scans and prints each printing layer, two end points of a preset path corresponding to the same position between the first boundary and the second boundary on each printing layer are respectively outside the first boundary and the second boundary, and the distance between the end points and the corresponding first boundary or second boundary randomly changes in the preset range.
In another embodiment, the overlapping area includes a second overlapping area formed by a plurality of scanning areas arranged in a direction perpendicular to the scanning direction, the second overlapping area includes a third boundary and a fourth boundary, the third boundary and the fourth boundary intersect with the boundary of the layer to be printed, and when the laser beam performs scanning printing on each printing layer, the boundary of the scanning width corresponding to the second overlapping area in the direction perpendicular to the scanning direction randomly fluctuates within the preset range outside the boundary of the second overlapping area.
In one embodiment, the scan width corresponding to the second overlap region in a direction perpendicular to the scan direction is adjusted by the number of scans of the laser beam when scanning the area corresponding to the third boundary and the fourth boundary. In another embodiment, the spot size of the laser beam for printing is adjusted by scanning the area corresponding to the third boundary and the fourth boundary when the scanning width corresponding to the second overlap area in the direction perpendicular to the scanning direction.
