Abstract
The utility model discloses an in-hole dust removal high pressure blower gun spray pipe for a PCB. The front end of the in-hole dust removal high pressure blower gun spray pipe for the PCB is a closed end, wherein side openings are formed in the wall of the in-hole dust removal high pressure blower gun spray pipe for the PCB, and the external diameter of a pipe body of the in-hole dust removal high pressure blower gun spray pipe for the PCB is smaller than the internal diameter of a through hole in the PCB. By means of the design, the high pressure blower gun spray pipe can be placed inside the through hole for close-range dust removal so as to achieve a good dust removal effect. The positions of the side openings and wind deflectors are reasonably designed so that the direction of dust removal wind can be further optimized to optimize the dust removal effect.
Description
Technical field
The utility model relates to a kind of tool of the PCB of making plate, specifically refers to dedusting high pressure air pressure gun jet pipe in a kind of pcb board hole.
Background technology
Whole PCB industry is just at high speed development, and the structure of product is also more and more diversified, and the quantity that wherein thick PCB plate occurs is also increasingly to increase, and aperture and thickness ratio on the PCB plate are more and more higher.Generally, to PCB twist drill hole the time, because of the diameter of the through hole on the PCB plate less, the PCB plate is thicker, in boring chip removal process mesoporous, more easily adhere to dust and burr, if it is clean that these dust and burr are not removed before electroless copper plating is electroplated, understand and directly affect pore size and hole wall quality, finally affect the vigour part and draw together and connect.At present the general dedusting method adopted is to utilize high pressure compressed gas dust blow off aperture and hole wall, but due to prior art be all outside that the high pressure air pressure gun is placed in to through hole utilize its faster wind speed dust and burr are blown out, because high pressure air pressure gun jet pipe is not placed in the closely dedusting of through hole inside, so some dust and burr still are attached to the inside of through hole, finally cause blow-time long, waste time and energy, and the dust removing effects uniformity is poor.
The utility model content
The purpose of this utility model is to overcome in prior art and high pressure air pressure gun jet pipe is not placed in to the closely defect of dedusting of through hole inside, provide a kind of and high pressure air pressure gun jet pipe can be placed in to the closely dedusting of through hole inside, with dedusting high pressure air pressure gun jet pipe in the pcb board hole that reaches good dust removing effects.
For achieving the above object, the technical solution of the utility model has been to provide dedusting high pressure air pressure gun jet pipe in a kind of pcb board hole, in described pcb board hole, dedusting high pressure air pressure gun jet pipe front end is blind end, in described pcb board hole, dedusting high pressure air pressure gun jet pipe tube wall is provided with side opening, and in described pcb board hole, dedusting high pressure air pressure gun jet pipe body overall diameter is less than pcb board through hole interior diameter.High pressure air pressure gun jet pipe can be placed in to the closely dedusting of through hole inside by above design, to reach good dust removing effects.
As preferably, described side opening edge is provided with guide vane.Can further to the air-out direction of high pressure air pressure gun jet pipe upper-side hole, be set by above design, be optimized dust removing effects.
As preferably, described side opening has a plurality of, is evenly distributed in dedusting high pressure air pressure gun jet pipe body front portion in described pcb board hole, and the guide vane relative set is a plurality of, and guide vane and side opening form air outlet jointly, and described air outlet is crisscross arranged.Such design makes the air-out direction of high pressure air pressure gun jet pipe upper-side hole more, and dedusting wind wind direction is more even.
Advantage of the present utility model and beneficial effect are: high pressure air pressure gun jet pipe can be placed in to the closely dedusting of through hole inside by above design, to reach good dust removing effects.Contralateral exposure position and guide vane carry out the wind direction that dedusting wind can be further optimized in rational design, optimize dust removing effects.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is not established guide vane;
Fig. 2 is the structural representation that the utility model is provided with guide vane;
Fig. 3 is that the utility model is used the status architecture schematic diagram.
In figure: 1, high pressure air pressure gun jet pipe body; 2, blind end; 3, side opening; 4, guide vane; 5, air outlet; 6, pcb board; 7, through hole.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Fig. 1 Fig. 2 Fig. 3, dedusting high pressure air pressure gun jet pipe in a kind of pcb board hole, in described pcb board hole, dedusting high pressure air pressure gun jet pipe front end is blind end 2, in described pcb board hole, dedusting high pressure air pressure gun jet pipe tube wall is provided with side opening 3, and in described pcb board hole, dedusting high pressure air pressure gun jet pipe body 1 overall diameter is less than pcb board 6 through hole 7 interior diameters.
Described side opening 3 edges are provided with guide vane 4.
Described side opening 3 has a plurality of, is evenly distributed in dedusting high pressure air pressure gun jet pipe body 1 front portion in described pcb board hole, and guide vane 4 relative set are a plurality of, guide vane 4 and the common formation air outlet 5 of side opening 3, and described air outlet 5 is crisscross arranged.
In actual use procedure, in the anterior insertion pcb board of dedusting high pressure air pressure gun jet pipe body in the pcb board hole 16 through holes 7, gases at high pressure blow out from side opening 3, due to the guiding function that guide vane 4 is arranged, gas can oppositely blow out to each along channeling direction, due to side opening 3, in the pcb board hole, dedusting high pressure air pressure gun jet pipe body 1 is anterior evenly arranges, so gas can blow to all directions uniformly through hole 7 is interior, dedusting high pressure air pressure gun jet pipe body 1 in the pcb board hole can also be moved up and down and rotates during use, dust removing effects further can be optimized like this.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
