Fig. 1 is the schematic diagram according to exemplary embodiment of the present invention.Gong machine (not shown) in the present embodiment adopts numerical control gong machine (CNC Routing), and gong machine is inputted in advance by program in the path that is about to gong cutter, and gong machine, according to program control gong cutter, carries out gong type according to this predetermined path.In the present embodiment, for the monoblock pcb board 1 of having produced, adopt the method processing PCB connecting plate of twice gong type in production line.
First, on monoblock pcb board 1, design PCB connecting plate district, gong type garbage area 3 and secondary gong type garbage area 4-1,4-2.Wherein, PCB connecting plate district comprises totally 6 the PCB veneers of two row's three row shown in a plurality of PCB veneer 2-1 of being printed on monoblock pcb board 1,2-2,2-3(Fig. 1) and the fillet 6-1 between adjacent PCB veneer, 6-2(Fig. 1 shown in 7 fillets).4 secondary gong type garbage areas shown in secondary gong type garbage area 4-1,4-2(Fig. 1) between adjacent PCB veneer.Secondary gong type garbage area 4-1,4-2 during by secondary gong type gong cutter the path of process limit.Gong type garbage area 3 is regions outside ChuPCB connecting plate district and secondary gong type garbage area 4-1,4-2 on monoblock pcb board 1.A gong type garbage area 3 during by a gong type gong cutter the path (heavy line in Fig. 1) of process and the outward flange of monoblock pcb board 1 limit.Fillet 6-1,6-2 can be between secondary gong type garbage area 4-1,4-2 and/or between secondary gong type garbage area 4-1 and a gong type garbage area 3.
Secondly, in the secondary gong type garbage area on monoblock pcb board 1, offer a plurality of the first location hole 5-1,5-2,5-3, utilize the first keeper via location hole 5-1,5-2,5-3, monoblock pcb board 1 to be fixed on gong machine.Wherein, the first location hole 5-1,5-2,5-3 can be the NPTH holes of manufacturing by modes such as boring, punchings.The aperture of the first location hole 5-1,5-2,5-3 is preferably more than or equals 1.5mm, more preferably 2.0~3.0mm.The quantity of the first location hole 5-1,5-2,5-3 is at least 2, is preferably 3 or 4, most preferably is 4.As shown in Figure 1, the first location hole 5-1,5-2,5-3 preferably lay respectively in disjunct secondary gong type garbage area.Also as shown in Figure 1, if the quantity of the first location hole 5-1,5-2,5-3 is more than 2, each first location hole 5-1,5-2,5-3 are preferably not on same straight line, but suitably stagger each other, so that raising fixed effect, correspondingly, each first keeper is not also on same straight line.In the present embodiment, the first location hole 5-3 is between two neighbouring PCB veneer 2-2,2-3, yet, the first location hole also can be between left and right adjacent two PCB veneer 2-1,2-2 (for example, be positioned at the below of fillet 6-2), or between adjacent two PCB veneer 2-1, the 2-3 that arrange along diagonal.The quantity of the first keeper is corresponding with quantity and the shape of the first location hole with shape.The first keeper can be locating pin (PIN nail) or alignment pin, bolt etc.Each first keeper inserts, hammers into or be screwed in the first corresponding location hole, and the bottom of each first keeper hammers into or is screwed on the working plate (not shown) setting firmly on gong machine.As selection, also can be first by the first keeper, monoblock pcb board 1 be fixed on fixedly on backing plate (not shown), more fixedly backing plate is fixed on gong machine.In addition, if the material of pcb board allows, can adopt upper PIN machine (Pinning Maching) step of generally using in PCB industry complete punching and follow closely solid operation.In addition, if need punching on PCB veneer, can when offering the first location hole, the hole in plate be made in the lump, and not need separately punching.
Then, with gong machine, carry out a gong type, gong type garbage area 3 gongs are removed.That is,, by inputting predefined parameter and/or the program in gong machine, control gong cutter and advance along the represented path of heavy line in Fig. 1.Because monoblock pcb board 1 is securely fixed on gong machine or fixture by location hole 5-1,5-2,5-3 and keeper, therefore, in the process of a whole gong type, the play of plate can not occur, so the management and control of gong molded dimension is stable, size is accurate, the super tolerance of nothing.In addition,, in location hole 5-1,5-2,5-3 secondary gong type garbage area 4-1, the 4-2 between adjacent PCB veneer, therefore, in the process of a whole gong type, gong cutter and keeper can not interfere.Preferably, three limits that the gong type garbage area 3 removing by gong type institute gong comprises PCB veneer 2-1,2-2,2-3 or the part on three limits are (for example, a part and the top on the left and right both sides that comprise PCB veneer 2-1, the part on the left side that comprises PCB veneer 2-2 and top and the right).In other words, by a gong type, three limits of part or all of PCB veneer or the part on three limits have been formed.
As shown in Figure 2, after a gong type, outside, the edge in PCB connecting plate district (in a gong type process gong cutter the path of process), be close to fixing some the second keepers 7 of edge of PCB veneer 2-1,2-2,2-3, in other words, the edge of the outer rim of the second keeper 7 and PCB veneer is tangent.If after a gong type, at the edge of PCB veneer 2-1,2-2,2-3, form groove, the location optimization of the second keeper 7 is positioned at this groove, to improve fixed effect.The quantity of the second keeper 7 is at least 2, is preferably 4 above (36 the second keepers 7 shown in Fig. 2).And fixing in order to implement better, preferably at other second keeper 7 that all arranges in every edge that gong has gone out of each PCB veneer.Because now PCB connecting plate district (each PCB veneer) is fixed on the working plate of fixing backing plate or gong machine, therefore can be first on fixedly backing plate or working plate accordingly position offer the second installing hole, again the second keeper 7 is fixed in the second installing hole, yet, because fixedly the common quality of backing plate is softer, therefore can omit the operation of offering the second installing hole.For example, can directly use PIN machine beats locating pin the second keeper is set.
Next, with gong machine, carry out secondary gong type, each secondary gong type garbage area 3 gongs are removed.That is, controlling gong cutter advances along the represented path of heavy line in Fig. 2.Because each secondary gong type garbage area 3 is removed by gong successively, therefore the first keeper that was originally arranged in secondary gong type garbage area 3 will lose its fixed effect gradually, yet, owing to having fixed the second keeper 7 after a gong type, therefore by the second keeper 7, whole PCB connecting plate and each PCB veneer are still firmly fixed, so secondary gong type still keeps, size management and control is stable, size is accurate, the advantage of the super tolerance of nothing.By secondary gong type, not only formed each PCB veneer 2-1,2-2,2-3, also formed fillet 6-1,6-2 between PCB veneer.Finally, by each second keeper 7 from gong machine or fixedly backing plate take off, obtained as shown in Figure 3 can shipment PCB connecting plate.
Be understandable that, above embodiment is only used to principle of the present invention is described and the exemplary embodiment that adopts, yet the present invention is not limited thereto.
In above-mentioned exemplary embodiment, three limits that gong type garbage area 3 comprises PCB veneer 2-1,2-2 or the part on three limits.Yet, be understandable that, a gong type garbage area also can only comprise the part on a limit of PCB veneer, two limits or a limit, two limits, correspondingly, secondary gong type garbage area can not only comprise the region between adjacent PCB veneer, also comprises the subregion of the edges of boards that are positioned at monoblock pcb board.In addition, a gong type garbage area can comprise a part for the four edges of PCB veneer, for example, in above-mentioned exemplary embodiment, a gong type garbage area 3 can extend to and comprise region 4-2, in this case, location hole 5-3 for example can be set in the right part of secondary gong type garbage area 4-1 and the position of location hole 5-2 symmetry.
In above-mentioned exemplary embodiment, by a gong type, gong is except four limits of monoblock pcb board, yet, be understandable that, if using the part on four limits of monoblock pcb board as a part of edge of PCB veneer or PCB connecting plate, gong type also can a gong except the appropriate section of the edges of boards of monoblock pcb board.In addition, one time gong type can once complete, and also can complete several times.In order to facilitate feed, during a gong type, the starting point of gong cutter and/or terminal can be positioned at the edge of monoblock pcb board.
In addition, be understandable that, gong type and secondary gong type can hocket, be that gong removes a gong type garbage area of a part, in corresponding PCB veneer edge, fix the second keeper, then gong is except the secondary gong type garbage area of appropriate section, and then gong removes gong type garbage area of another part again ... with this, circulate.
In above-mentioned exemplary embodiment, the second keeper is positioned at the groove at PCB veneer edge.Yet, be understandable that, even if the edge of PCB veneer does not have groove, also can implement to fix by other fixedly the second keeper of right quantity in the edge, upper and lower, left and right at whole PCB connecting plate.
In above-mentioned exemplary embodiment, before secondary gong type, the first keeper is not removed.Yet, be understandable that, for example, in the situation that secondary gong type garbage area is narrower, in the process of secondary gong type, gong cutter may interfere with the first keeper.Therefore, also can be after the first keeper be removed, then carry out secondary gong type.
In above-mentioned exemplary embodiment, the PCB connecting plate of manufacturing is the structure of two row's three row, yet, PCB connecting plate also can have other arrangement, such as four row's one row, three row's four row etc., as long as the quantity of PCB veneer is more than 2 or 2, and leaves the region of at least 2 location holes of enough settings in monoblock pcb board.
In above-mentioned exemplary embodiment, utilize monoblock pcb board to manufacture a PCB connecting plate with fillet.Yet the present invention also can be applicable to utilize monoblock pcb board to manufacture the situation of a plurality of PCB connecting plates and/or a plurality of PCB veneers.For the situation of manufacturing a plurality of PCB veneers, monoblock pcb board can only comprise PCB veneer, gong type garbage area and secondary gong type garbage area and not comprise fillet.In addition, based on the having or not of fillet, the arranging situation of PCB veneer and the optimization situation of gong cutter travel path, it can be also a plurality of that the quantity of gong type garbage area and secondary gong type garbage area can be respectively one.
In above-mentioned exemplary embodiment, gong type and secondary gong type are carried out by same gong machine.Yet, be understandable that, one time gong type can be carried out by different gong machines from secondary gong type.For example, monoblock pcb board can be fixed to fixedly on backing plate, when a gong type by the first keeper, fixedly backing plate is fixed on the first gong machine, before secondary gong type, the second keeper is also fixed on to this fixedly on backing plate, and by this fixedly backing plate be fixed on the second gong machine.
In above-mentioned exemplary embodiment, adopt numerical control gong machine to carry out gong plate, and the path parameter of gong type and secondary gong type is pre-entered in gong machine.Yet the present invention also can adopt semi-automatic gong machine, manual gong machine or semi-automatic miller, hand miller to implement.In addition, in above-mentioned exemplary embodiment, the path of gong cutter there is no need to preset or is labeled in advance on monoblock pcb board, but can directly carry out gong type according to the profile of PCB veneer or PCB connecting plate.
In addition, be understandable that, for the situation that adopts numerical control gong machine, the parameter of twice location and twice gong type, program etc. can be offered in the lump to the gong type operation form of drawing (for example with), by the automations such as gong type operation amenable to process and drawing carry out each location and gong type operation.
