Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Example one
The embodiment of the application provides a gong journey design method suitable for PCB board production process, can realize discerning gong journey reference area on the PCB makeup, select the gong sword of equidimension not in proper order in gong journey reference area to carry out the line design of walking of appearance and inside groove, obtain walking the line design, select to walk the line design and walk the regional difference of gong journey and be less than the radial line segment of the gong sword that corresponds and regard as gong journey, and then automatic generation gong journey and can realize the automatic selection of the gong sword that corresponds different gong journeys.
Specifically, with reference to fig. 1 and 2, the method comprises:
acquiring a jigsaw file displaying a main jigsaw pattern shape, wherein the main jigsaw is formed by splicing at least two sub jigsaws;
constructing at least two network connection graphs to form a first network connection graph set based on lines on the jigsaw files, selecting a network connection graph with the largest external matrix area in the first network connection graph set as a total board network, deleting the total board network in the first network connection graph set to obtain a second network connection graph set, carrying out inclusion comparison on all network connection graphs in the second network connection graph set, if a certain network connection graph is contained in the rest network connection graphs, the network connection graph is a gong groove graph, and the gong groove graph and the total board network form a gong stroke reference area;
sequentially traversing and acquiring the routing of each routing knife according to the routing knife radius from big to small, wherein the routing of each routing knife is acquired in the following manner: and taking the milling cutter radius of the milling cutter as a zoom distance, expanding the zoom distance outwards for an unmarked area of a milling reference area to obtain a shape routing, retracting the unmarked area of the milling reference area inwards for the zoom distance to obtain an inner groove routing, selecting a line segment of which the distance between the shape routing and the inner groove routing and the unmarked area is smaller than the milling cutter radius, taking the line segment as the milling cutter radius of the milling cutter and taking the line segment as the marked area of the milling reference area.
In the scheme, the gong-and-groove pattern and the total board network form the gong-and-stroke reference area. The gong-groove graph is a second network connectivity graph contained in the network connectivity graph of the sub-panels.
Specifically, in the step of obtaining a jigsaw file displaying a main jigsaw pattern shape, wherein the main jigsaw is formed by splicing at least two sub jigsaw boards, GKO jigsaw files corresponding to the main jigsaw pattern shape are read according to a Gerber protocol, a main board composed of different sub jigsaw boards in the main jigsaw corresponds to a jigsaw wiring line corresponding to each sub jigsaw board, and the jigsaw file displays jigsaw wiring corresponding to each sub jigsaw board.
It is worth mentioning that the scheme is suitable for main jointed boards with various patterns, and the scheme does not limit the main jointed boards.
In the "constructing at least two network connectivity graphs to form a first network connectivity graph set based on the lines on the makeup document," the network connectivity graph refers to a closed connectivity graph formed by the lines of the makeup document, and specifically, the network connectivity graph is formed by connecting straight lines and curved lines in the makeup document through touch.
Because the jigsaw file has at least two sub jigsaw and a main board for bearing the sub jigsaw, at least two network connection graphs are necessarily formed, and the network connection graph corresponding to the main board is necessarily required to be deleted before the comparison of the network connection graphs. The network connection diagram corresponding to the master board is deleted based on the fact that the area of the network connection diagram corresponding to the master board is the largest characteristic of all the network connection diagrams.
Correspondingly, the method further comprises the following steps of selecting the network connection graph with the largest external matrix area in the first network connection graph set as the total board network: and acquiring the area of an external matrix of each network connected graph in the first network connected graph set, and selecting the network connected graph with the largest area of the external matrix as a total board network.
And after the network connection graph corresponding to the main board is eliminated, the remaining network connection graphs can be subjected to inclusion comparison operation so as to distinguish the sub-jointed board network connection graph from the gong-groove graph. Because the sub-jointed boards on the main board are not overlapped, that is, each sub-jointed board is necessarily independently arranged on the main board, the network connection diagram and the gong-groove diagram of the sub-jointed boards can be distinguished by a method of containing comparison, and if the contained relation exists, the contained network connection area corresponds to a non-sub-jointed board.
Specifically, all network connectivity graphs are subjected to inclusion comparison at this time, and if the network connectivity graphs and the other network connectivity graphs do not have inclusion relations, the network connectivity graphs are sub-jigsaw network connectivity graphs; if the two network connection graphs have an inclusion relationship, the included network connection graph is a routing graph, the network connection graph including the first waste material area is a sub-jointed board network connection graph, the sub-jointed board network connection graph and the routing graph can be distinguished through the distinction, and the routing graph is a graph needing routing by a routing knife.
Illustratively, if the A network connectivity map is contained in the B network connectivity map, and the B network connectivity map is not contained in any network connectivity map, the A network connectivity map is used as a gong-slot pattern, and the B network connectivity map is used as a sub-tile network connectivity map. Illustratively, if the A network connectivity map is contained in the B network connectivity map and the B network connectivity map is contained in the C network connectivity map, the A network connectivity map and the B network connectivity map are used as gong-slot patterns, and the C network connectivity map is used as a sub-jigsaw network connectivity map.
Routing is divided into two types: the shape routing adopts a routing knife to route routing at the outer side relative to the main board network, and the inner groove routing adopts a routing knife to route routing at the inner side relative to the main board network. According to the scheme, the routing arrangement is carried out on the gong knives with different gong knives in different radius, the gong knives with the largest gong knife radius are selected for use to carry out the gong program design, then the gong knives with the largest gong knife radius are gradually reduced to carry out the gong program design, the beneficial effect of doing the like is that the unnecessary routing can be reduced, and meanwhile the accuracy of the gong program can be guaranteed.
It should be noted that, in the step of "sequentially traversing and acquiring the routing of each routing knife from large to small according to the radius of the routing knife", the routing of a first routing knife with a relatively large radius of the routing knife is calculated first, and then the routing of a second routing knife with a relatively small radius of the routing knife is calculated sequentially, and the first routing knife and the second routing knife are relative concepts.
And when the routing of each routing knife is calculated, the unmarked area is the routing reference area with the marked area removed. For example, when a first gong cutter with the largest radius of the gong cutters is calculated, the gong stroke reference area does not have a marked area, and the unmarked area is the whole gong stroke reference area; and when the routing of a second or Nth routing knife with a smaller routing knife radius is calculated, the routing reference area has a marked area, and the unmarked area is the routing reference area without the marked area.
In the step of expanding the scaling distance outwards for the shape of the unmarked area of the routing reference area, the scaling distance is expanded outwards for the unmarked area corresponding to the total board network to obtain a shape routing, and the total board network can be routed by using the shape routing. Specifically, the scaling distance is expanded outwards for the unmarked routing of the total board network, so as to obtain the outline routing.
In the step of retracting the unmarked area of the routing reference area inwards by the zoom distance to obtain the internal groove routing, retracting the unmarked area corresponding to the routing graph inwards to obtain the internal groove routing, and routing redundant waste materials by using the internal groove routing. Specifically, the unmarked routing of the routing image is retracted inwards by the zoom distance to obtain the internal groove routing.
In the step of selecting a line segment, of which the distance between the outer trace and the inner groove trace and the unmarked area is smaller than the radius of a routing knife, as the routing of the routing knife, the outer trace is overlapped on the unmarked area, and a first line segment, of which the distance between the unmarked area and the outer trace is smaller than the radius of the routing knife, is selected; and overlapping the internal groove routing with the unmarked area, selecting a second line segment on the unmarked area, wherein the distance between the unmarked area and the internal groove routing is smaller than the radius of the routing knife, and traversing the first line segment and the second line segment to be used as the routing of the routing knife.
This is done better than: if the distance is larger than the radius of the routing knife, the routing knife cannot touch the shape line, and if the distance between the shape routing line and the unmarked area is larger than the radius of the routing knife, the routing knife cannot touch the shape deformation because the routing knife has a certain thickness. Similarly, if the distance between the inner groove routing and the unmarked area is greater than the radius of the routing knife, the routing knife cannot touch the inner groove routing.
In the scheme, all the gongs and the knifes are traversed to obtain the gong courses corresponding to different gongs and the gongs until no unmarked area exists in the gong course reference area.
Exemplarily, if two gongs are provided, the radius of the gong knife of a first gong knife is greater than that of a second gong knife, the radius of the gong knife of the first gong knife is selected as a first scaling coefficient, the radius of the gong knife of the first gong knife is taken as a first scaling distance, the first scaling distance is outwards expanded for an unmarked area of a gong-run reference area to obtain a first contour routing, the unmarked area of the gong-run reference area is inwards retracted for the first scaling distance to obtain a first internal groove routing, a line segment of which the distance between the first contour routing and the unmarked area is smaller than the radius of the gong knife is selected as the gong run of the first gong knife, and the line segment is taken as a marked area of the gong-run reference area;
selecting the milling cutter radius of a second milling cutter as a second zooming distance, taking the milling reference area without the first milling cutter as an unmarked area, outwards expanding the unmarked area of the milling reference area to obtain a second outline routing, inwards retracting the unmarked area of the milling reference area to obtain a second internal groove routing, selecting the second outline routing and the second internal groove routing and the unmarked area, wherein the interval between the second outline routing and the unmarked area is smaller than the segment of the milling cutter radius, and taking the milling cutter radius of the second milling cutter as the segment of the milling cutter to be taken as the marked area of the milling reference area. And the gong stroke of each gong knife is obtained by analogy.
Illustratively, the gong sword is realized to acquiescence three gongs of different diameters, and the diameter of gong sword is respectively: 1.6mm, 1.0mm, 0.8 mm. Firstly, a first gong knife (1.6mm) is selected, the routing of the gong stroke reference area is zoomed inwards (outwards), the external routing is zoomed outwards, the internal routing is zoomed inwards, and the zooming distance is the radius of the first gong knife. And comparing the zoomed shape and the internal groove routing with the routing reference area respectively, marking the line segment meeting the requirement that the distance is less than or equal to the radius of the first routing knife, and traversing the marked line segment to generate the routing of the first routing knife. Then a second gong cutter (1.0 mm) is selected, the unmarked line segments are scaled, and then the gong stroke of the second gong cutter is generated by adopting the generation algorithm of the first cutter. And similarly, calculating the routing of the third knife (0.8mm) to generate the routing of the third knife.
The processed process file is exported as a Gerber file, and the Gerber file is provided to the factory for actual PCB processing.
