Abstract
The utility model discloses a comprises a box bod, , including glass carrier platform and the sealed lid of mai la, the limit portion of glass carrier platform is provided with aspirating hole, its characterized in that: the wheat draws sealed lid to draw and set up a plurality of between two -layer wheat the is drawn copper air guides flat boards that are parallel to each other including frame, the two -layer wheat of setting in the frame. The utility model discloses comprises a box bod, , dull and stereotyped through setting up copper air guide in two -layer wheat between drawing, copper air guide flat board enables the wheat and draws and keep leveling, and in vacuum process, the problem that can avoid the wheat to draw the fold to lead to the air to be taken away fast need not the manual work of rethread scraper blade and catches up with gas, and evacuation efficiency is higher, and the evacuation quality is more stable, can avoid the exposure problem of exposing and breathing in and harmfully arousing.
Description
Technical field
The utility model is related to a kind of exposing machine of circuit board, more particularly to a kind of gas operated device of exposing machine of circuit board.
Background technology
Electronic product has turned into indispensable role in daily life, and electronic product convenience of being made the life better to people has
Very big contribution, and circuit board is the core component of the electronic products such as mobile phone, computer, TV.
Circuit board will be by exposure process in manufacturing process, and the effect of exposure is the pattern offer according to required for client
Line map.Exposure operation process is that first be placed on the egative film of circuit board on exposure machine worktable by operator, then by exposure machine
Mai Lagai restart the vacuum extractor of exposure machine on the table, then and take the air of the wheat side of leaving behind away, work as vacuum
After reaching requirement, exposure machine is exposed operation again.
But, because wheat draws quality softer, in vacuum, wheat draws easily corrugation, cause to vacuumize it is less efficient,
And vacuumize second-rate；Quality is vacuumized in order to improve in the prior art, generally also needs to operator with one piece of scraper plate in wheat
Pull on and scraped, to drive unnecessary air away, improve exposure quality.But manually drive air away with scraper plate, increased operation
Step so that production efficiency is relatively low, can not be completely eliminated the bad technical problem of exposure air-breathing.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of circuit board outer layer exposure machine gas operated device, existing to solve
Having exposure machine needs manually to drive air away, there is low production efficiency, easily produces the bad technical problem of exposure air-breathing.
The utility model circuit board outer layer exposure machine gas operated device, including glass holder platform and Mai La closures, it is described
The edge of glass holder platform is provided with aspirating hole, the wheat draw closure include frame, the two-layer wheat being arranged in frame draw,
And it is arranged on some pieces of copper air guide flat boards being parallel to each other between the drawing of two-layer wheat.
Further, the edge of the glass holder platform is additionally provided with the air slot of connection aspirating hole.
Further, it is additionally provided with locating pin on the glass holder platform.
Further, the edge of the frame is provided with sealing strip.
The beneficial effects of the utility model：
The utility model circuit board outer layer exposure machine gas operated device, is put down by setting copper air guide between the drawing of two-layer wheat
Plate, copper air guide flat board can make wheat draw holding smooth, in vacuum, be avoided that wheat drawing fold causes air fast
The problem that speed is taken away, without manually catching up with gas by scraper plate again, vacuumizes in hgher efficiency；And it is more stable to vacuumize quality, is avoided that
The exposure bad exposure problems for causing of air-breathing.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of base plate for silk screen printing；
Fig. 2 is the cross section structure diagram that wheat draws closure.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
The present embodiment circuit board outer layer exposure machine gas operated device, including glass holder platform 1 and Mai La closures, the glass
The edge of glass holder platform is provided with aspirating hole 2, and the wheat draws closure to be drawn including frame 3, the two-layer wheat being arranged in frame
4 and be arranged on two-layer wheat draw between some pieces of copper air guide flat boards 5 being parallel to each other.
The present embodiment circuit board outer layer exposure machine gas operated device, copper air guide flat board is set by between the drawing of two-layer wheat,
Copper air guide flat board can make wheat draw holding smooth, in vacuum, be avoided that wheat drawing fold causes air quick
The problem taken away, without manually catching up with gas by scraper plate again, vacuumizes in hgher efficiency；And it is more stable to vacuumize quality, is avoided that exposure
The bad exposure problems for causing of light air-breathing.
Used as the improvement to the present embodiment, the edge of the glass holder platform is additionally provided with the air guide of connection aspirating hole 2
Groove 6, the air of the edge of glass holder platform 1 can be quickly pumped by air slot, be can further improve and vacuumized efficiency.
As the improvement to the present embodiment, locating pin 7 is additionally provided with the glass holder platform, is laying circuit board bottom
During piece, can faster location and installation egative film by locating pin, it is ensured that exposure image position is correct.
Used as the improvement to the present embodiment, the edge of the frame is provided with sealing strip 8, is carried glass by sealing strip 8
The edge of part platform is sealed, and be can further improve and is vacuumized efficiency, keeps vacustat.
As the improvement to the present embodiment, also including the vacuum cup 9 positioned at glass holder platform both sides, due to circuit board
Egative film is relatively thin, and egative film is removed from glass holder platform with vacuum cup just after exposure, and egative film takes out the simpler side of operation
Just, operating efficiency can be improved.
Finally illustrate, above example is only used to illustrate the technical solution of the utility model and unrestricted, although ginseng
The utility model has been described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, without deviating from the objective and model of technical solutions of the utility model
Enclose, it all should cover in the middle of right of the present utility model.
