Specific embodiment

For the ease of the understanding of those skilled in the art, the utility model is made below with reference to embodiment and attached drawing further Explanation, the content that embodiment refers to not is restriction to the utility model.The utility model is carried out below in conjunction with attached drawing Detailed description.

As shown in Fig. 2, a kind of PCB jigsaw provided by the utility model detects jig, including pedestal 4, it is set to pedestal 4 Dials jig 1, the multiple indicator lights 2 for being set to dials jig 1 and for being indicated to the bad element plate in PCB jigsaw Dial plate 3, the dial plate 3 are provided with multiple mark through-holes 31 corresponding with the position of each unit plate in PCB jigsaw；It is more The position of a indicator light 2 is corresponding with the position of each unit plate in PCB jigsaw respectively；The dials jig 1, which is equipped with, to be used In more probes 11 for contradicting each unit plate in PCB jigsaw respectively.Specifically, the inspection of probe 11 and indicator light 2 with the external world Device is surveyed to be electrically connected.

In practical applications, when being detected to PCB jigsaw, PCB jigsaw is lain on the probe 11 of dials jig 1, with Detect this detection jig to each unit plate of PCB jigsaw；After the completion of detection, on dials jig 1 with good cell board The corresponding indicator light 2 in position can sapphirine；Indicator light 2 corresponding with the position of bad element plate is just bright on dials jig 1 It is red；Then, inspector can be used indicator board and cover on PCB splice plate, and allow each mark through-hole 31 on dial plate 3 Corresponding with the position of each unit plate, then inspector can be through mark through-hole 31 to corresponding with 2 shiny red of indicator light Cell board indicated.The utility model is simple and compact for structure, can accurately indicate bad cell board convenient for inspector, To improve Detection accuracy and guarantee the yield and quality out of PCB jigsaw.

In the technical scheme, the dials jig 1 includes the bottom plate 12 set gradually from bottom to up, probe fixed plate 13, the first guide plate 14, fiberboard 15 and the second guide plate 16, the dials jig, which is equipped with, runs through the first guide plate 14, fiberboard 15 With multiple jacks 111 of the second guide plate 16, probe 11 is set to probe fixed plate 13 and is located in jack 111, and probe 11 passes through It threads a needle disk jig 1.Specifically, the quantity of the fiberboard 15 of the present embodiment is two pieces.The bottom plate 12, probe fixed plate 13 and One guide plate 14 successively stacks, between first guide plate 14 and fiberboard 15, between adjacent two pieces of fiberboards 15 and fiberboard 15 and second are equipped with insulated column 112 between guide plate 16.The design of the structure is simply ingenious, and probe 11 can be effectively avoided and wear The problem of dials jig 1 bends is threaded a needle high-efficient, and effect of threading a needle is good.

In the technical scheme, multiple indicator lights 2 are all set in probe fixed plate 13, and the dials jig is equipped with and passes through Multiple light transmission through-holes 113 of the first guide plate 14, fiberboard 15 and the second guide plate 16 are worn, multiple light transmission through-holes 113 appear more respectively A indicator light 2.The light that indicator light 2 is issued can be radiated on corresponding cell board through light transmission through-hole 113；The structure Indicator light 2 is effectively arranged in the position for not influencing the detection of PCB jigsaw, while indicator light 2 being enable accurately to irradiate by design Onto cell board, in favor of improving the detection accuracy of this detection jig.

In the technical scheme, the fiberboard 15 with a thickness of 1mm.The thickness and the second guide plate of first guide plate 14 16 thickness is 3.5mm.The height of the insulated column 112 is 8mm.On the one hand the design of the size facilitates drilling, another party Face will not influence wearing for probe 11 because thickness is blocked up, and probe 11 can also be made to be less likely to occur to be bent when detecting.

In the technical scheme, the pedestal 4 includes base plate 42 and the support column 41 for being set to base plate 42, the branch One end of dagger 41 is connect with base plate 42, and the other end and the dials jig 1 of support column 41 are detachably connected.The pedestal 4 is set Meter can provide enough support forces for dials jig 1, can also be convenient for the replacement of different types of dials jig 1, to improve The using flexible of the utility model.
