Anti-welding main difficulty point be concentrated mainly on printing consent, in the prior art, the pcb board handled to consent is placed on absorption
On platform, air-breathing is carried out so that ink is further by ink out of top filling consent and by absorptive table in the other side of circuit board
It leads to which in consent, because the adsorption hole hole location of absorptive table is fixed and invariable, and the hole location of the anti-welding consent of different pcb boards is not
Together, therefore when the hole location of adsorption hole and anti-welding consent accurately pcb board anti-welding production consent when corresponding to can not often occur because of air-breathing
The problem of unevenly leading to anti-welding consent bleed, in addition, there are gaps between the absorptive table and pcb board placed on it
When, also resulting in leads to anti-welding consent bleed because air-breathing is uneven.
Therefore, it is necessary to be improved existing pcb board air-breathing strike through device.
Utility model content
The purpose of this utility model is to provide one kind to prevent the anti-welding production consent of pcb board from occurring causing because air-breathing is uneven
The pcb board air-breathing strike through device of the problem of anti-welding consent bleed.
In order to realize above-mentioned purpose of utility model, the utility model provides a kind of pcb board air-breathing strike through device, feature
It is, including the absorptive table of loading plate and upper surface with air suction function for carrying pcb board, have on the pcb board anti-
Consent is welded, the loading plate has the cavity formed with the anti-welding one-to-one air hole of consent and upward recess, institute
Loading plate is stated to be placed on the absorptive table to carry out air-breathing strike through to the pcb board being carried on the loading plate.
Further, the loading plate has the substrate of horizontally extending formation and the outer rim edge from the substrate
The support plate that short transverse is downwardly extending, the cavity are crowded around by the substrate and the support plate.
Further, there is the absorptive table at least one to be used to suck the suction hole of its upper air.
Further, the suction hole is uniformly arranged in array.
Further, the support plate lower surface and the upper surface of the absorptive table fit closely setting.
Further, the loading plate has the adsorption hole being formed there through by the loading plate along short transverse, the suction
Attached hole be used for the absorptive table carry out air-breathing strike through when adsorb the pcb board placed on it so that the pcb board with it is described
Loading plate fits closely.
Further, the adsorption hole is uniformly distributed in the loading plate surrounding.
The technical effect of the utility model are as follows: by be set to the loading plate cavity and with the anti-welding consent one
One corresponding air hole is to realize the uniform air-breathing strike through to the pcb board, by the absorption for being set to the loading plate periphery
The pcb board placed on it is adsorbed in hole so that the pcb board is fitted closely with the loading plate, avoids in air-breathing strike through when institute
Stating has gap and influences air-breathing strike through effect between pcb board and the loading plate.
Detailed description of the invention

Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.
Embodiment
A kind of pcb board air-breathing strike through device as shown in Figure 1 to Figure 3, including for carrying pcb board 1 loading plate 2 and
Surface has the absorptive table 3 of air suction function, has anti-welding consent 11 on the pcb board 1, and the loading plate 2 has to be prevented with described
It welds the one-to-one air hole 21 of consent 11 and the cavity 22 of recess formation, the loading plate 2 is placed in the absorptive table 3 upwards
On to carry out air-breathing strike through to the pcb board 1 that is carried on the loading plate 2.
Preferably, the loading plate 2 has the substrate 23 of horizontally extending formation and from outside the substrate 23
The support plate 24 that edge is downwardly extending along short transverse, the cavity 22 crowded around by the substrate 23 and the support plate 24 and
At.
Preferably, there is the absorptive table 3 at least one to be used to suck the suction hole 31 of its upper air.
