Abstract
The utility model provides a filter plug for production of printed circuit board's filter equipment, including hollow plastic net pipe the pipe shaft of plastic net pipe comprises the plastic net piece of cylinder, rectangular skeleton that the plastic net piece was arranged by the annular and alternately constituting along the annular ring that rectangular skeleton length direction evenly arranged, and the fretwork hole of rectangular skeleton and a plurality of rectangles of annular ring chiasma formation, the outside parcel that encircles of plastic net piece of cylinder has filtering gauze, and the filtering gauze outside is provided with the band, is provided with the buckle on the band, and filtering gauze was fixed on the plastic net piece after the band was tightened. This plug adopts filtering gauze to replace the filter pulp, has improved the life who filters the plug, has reduced use cost.
Description
Technical field
This utility model relates to the tool of production of a kind of printed circuit board (PCB), particularly relates to a kind of printed circuit board (PCB) raw
The filter plug of the defecator produced.
Background technology
In conventional printed circuit board (PCB) production process, need to use the chemical medicinal liquid being used for sinking copper to filter dress
Put and filter, to avoid the appearance of printed circuit board surface particulate matter.Defecator mainly uses filtration
Plug filters, the filter cotton that its surface of current filter plug uses, single use, use cost
Relatively big, waste more.
Utility model content
In order to solve problem present in background technology, this utility model provides a kind of for printed circuit board (PCB)
The filter plug of the defecator produced, this plug uses filtration gauze to replace filter cotton, improves filtration core
In the service life of rod, reduce use cost.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of filter plug of the defecator produced for printed circuit board (PCB), including the plastics webmaster of hollow,
One end of plastic tube capping is closed, and the other end stays open, it is characterised in that the pipe of described plastics webmaster
Body is made up of columnar plastic deeping, and plastic deeping is by the strip skeleton being circular layout and long along strip skeleton
The annular ring intersection that degree direction is evenly arranged is constituted, and strip skeleton and annular ring intersect to form engraving of multiple rectangle
Emptying aperture, columnar plastic deeping external rings, around being enclosed with filtration gauze, is provided with band outside filtration gauze,
Being provided with buckle on band, band is tightened rear filtration gauze and is fixed on plastic deeping.
Described band is evenly arranged along the length direction of plastics webmaster.
The beneficial effects of the utility model are: after use, can take off drainage screen easily, be carried out more
Change, it is achieved the long-time use of filter plug, improve service life, reduce use cost.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further illustrated
Fig. 1 is the structural representation of filter plug described in the utility model；
Detailed description of the invention
This utility model is further described by explanation and detailed description of the invention below in conjunction with the accompanying drawings:
Embodiment 1
As it is shown in figure 1, a kind of filter plug, the defecator in printed circuit production process, including
The plastics webmaster 1 of hollow, one end of plastic tube 1 capping 2 closing, the other end stays open, plastics webmaster
The pipe shaft of 1 is made up of columnar plastic deeping 4, and plastic deeping is by the strip skeleton being circular layout with along strip
The annular ring intersection that backbone length direction is evenly arranged is constituted, and strip skeleton and annular ring intersect to form multiple square
The hollow hole of shape, columnar plastic deeping 4 external rings is around being enclosed with filtration gauze 5, outside filtration gauze 5
Being provided with band 3, band 3 is provided with buckle 1, filtration gauze 5 is fixed on after being tightened by band 3 and moulds
In material mesh sheet, band 3 is evenly arranged along the length direction of plastics webmaster 1.
When changing filtration gauze 5, open buckle 1, loosen band 3, by filtration gauze 5 from plastic deeping 4
On take off, then change new filtration gauze 5, band 3 tightened the replacing that can complete filtration gauze.
It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, permissible
Above-mentioned embodiment is carried out various amendment, changes and combine, and think this amendment, change and combine
Within the scope of originality thought.
