Description

PCB (printed circuit board) splitting jig

[ technical field ] A method for producing a semiconductor device

The utility model relates to a PCB divides board tool, especially a PCB divides board tool that can guarantee that PCB can not take place the skew at the in-process of cutting.

[ background of the invention ]

At present, for a small-sized PCB (Printed Circuit Board) or an irregular-shaped PCB, a Board splicing technology or a method for adding auxiliary edges is required to be adopted for producing and welding the PCB, after the production and the test of the PCB are completed, the PCB is required to be placed on a Board splitting jig, the auxiliary edges (generally, two auxiliary edges which are symmetrical left and right) of the PCB are cut and removed by a milling cutter through a Board splitting machine, and the generated dust is absorbed and removed.

In the actual cutting process, when the locating column is not hard up, and one of them supplementary limit has cut the back of accomplishing, the spacing module of direction will lose effect, and the condition that PCB can take place the skew under the effort of board separator milling cutter probably will damage the circuit of PCB when cutting other nodes.

In view of this, the utility model provides a PCB divides board tool that can guarantee that PCB can not take place the skew at the in-process of cutting.

[ Utility model ] content

The to-be-solved technical problem of the utility model is to provide a PCB divides board tool that can guarantee that PCB can not take place the skew at the in-process of cutting.

For solving above-mentioned technical problem, a PCB divides board tool, it is used for a firm PCB, and this PCB both sides respectively are provided with an auxiliary edge, adopt the nodal connection between this auxiliary edge and this PCB main part, are provided with a milling flutes between node and node, still are provided with a plurality of locating hole on this PCB, and this PCB divides board tool to include:

the bottom plate is used for being fixed on a workbench of the plate separator;

the four guiding limiting modules are respectively in an L shape and are respectively fixed at four corner positions of the bottom plate, the four guiding limiting modules surround a placing area on the bottom plate, the placing area is used for placing the PCB right, and the guiding limiting modules can guide to place the PCB and partially limit the PCB after the placement is finished;

the positioning columns are arranged in the placing areas on the bottom plate corresponding to the positions of the positioning holes of the PCB and are used for being clamped into the positioning holes to partially limit the PCB; and

the clamping plate limiting modules are fixed on the bottom plate and located below the auxiliary edge of the PCB which is placed, a clamping head is arranged at the upper end of each clamping plate limiting module, and the clamping head can be clamped in the milling groove and partially limit the PCB.

Preferably, the cartridge is provided with a chamfer.

Preferably, the card board limiting module is fixed on the bottom plate through two screws.

Compared with the prior art, the utility model discloses PCB divides board tool borrows by this bottom plate, this direction spacing module, this reference column and the spacing module's of this cardboard cooperation to use for this PCB can not produce when cutting this supplementary limit in both sides and rock and can not take place the skew of position, thereby ensures that this PCB can not take place to damage when cutting this supplementary limit.

[ detailed description ] embodiments

Please refer to fig. 1 to 4, the utility model provides a PCB divides board tool, it is used for a firm PCB1, this PCB1 both sides respectively are provided with an auxiliary edge 11, adopt the nodal connection between this auxiliary edge 11 and this PCB1 main part, are provided with a milling flutes 12 between node and node, still are provided with a plurality of locating hole 13 on this PCB1, this PCB divides board tool to include:

the bottom plate 2 is used for being fixed on a workbench of the plate separator;

the four guiding and limiting modules 3 are respectively in an L shape and are respectively fixed at four corner positions of the bottom plate 2, the four guiding and limiting modules 3 enclose a placing area 31 on the bottom plate 2, the placing area 31 is used for placing the PCB1 right, and the guiding and limiting modules 3 can guide and place the PCB1 and partially limit the PCB1 after the placing is completed;

a plurality of positioning posts 4, disposed in the placement area 31 of the base plate 2 corresponding to the positioning holes 13 of the PCB1, for being inserted into the positioning holes 13 to partially limit the PCB 1; and

the plurality of clamping plate limiting modules 5 are fixed on the bottom plate 2 and located below the auxiliary edge 11 of the PCB1, a clamping head 51 is arranged at the upper end of each clamping plate limiting module 5, the clamping head 51 can be clamped in the milling groove 12 and partially limit the PCB1, and in the embodiment, the clamping plate limiting modules 5 are fixed on the bottom plate 2 through two screws.
