Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, servicing unit is vacuumized when a kind of half tone of the present embodiment exposes, including hardboard 2,
Soft board 3 and the pad between hardboard 2 and soft board 31, pad 1 are tower structure, and the top of pad 1 pastes with hardboard 2
Close, the bottom of pad 1 is fitted with soft board 3, when light source exposure is carried out to half tone 4, the printing of half tone 4 faces up, and the film 5 is put
Fitted with exposure machine in the top of the top of the printing surface of half tone 4, and the film 5, this vacuumizes servicing unit and is placed in scraping for half tone 4
The lower section of knife face, soft board 3 is adjacent to half tone 4, and four edges of half tone 4 are respectively equipped with a wireway 6, and the conduit 6 leads to exposure
At the bleeding point of ray machine vavuum pump, the residual air on exposure machine table top can be effectively excluded, be brought into close contact half tone and the film,
Improve the exposure effect of half tone.When hardboard 2 applies pressure to the top of pad 1, the bottom of pad 1 is applied pressure to by soft board 3
Half tone 4, makes half tone 4 be in close contact and fit with the film 5, and the bottom of pad 1 is expanded the active force of half tone 4 from center to surrounding
Dissipate, air is drained to surrounding from center between half tone 4 and the film 5, the exposure effect of half tone 4 is more preferable.
In the present embodiment, pad 1 includes the identical and of different sizes sheet material of some shapes, and sheet material is according to from bottom to top face
The rule that product is successively successively decreased stacks fixation with one heart, and specifically, sheet material is circular or polygon, by rubber sheet or plastic sheet system
Into with certain toughness, the thickness of each layer of sheet material is identical, and the pad 1 is provided with 3~10 layer of sheet material, and the area of sheet material is under
And on successively reduce in proportion, it is preferable that fixed by adhesives between each sheet material, and pad 1 gross thickness be no more than net
Highly, when the top to pad 1 applies pressure, the bottom of pad 1 is to the active force of half tone 4 from center to four for the screen frame of version 4
Week diffusion, can more thoroughly drain the air between half tone 4 and the film 5；Soft board 3 uses sponge plate, to half tone 4 and the film
5 when being vacuumized, and half tone 4 and the film 5 are not fully-flattened, and subregion depression or prominent is had between half tone 4 and the film 5,
Soft sponge plate can act on these regions, and the air in the region can be extruded when being pressed to sponge plate, and to half tone 4
The space of a whole page has buffer protection function, specifically, sponge plate of the soft board 3 using shore hardness between 36 degree to 50 degree, if sponge
Too soft, cushioning effect cannot squeeze out the gas between the film 5 and half tone 4 greatly, then be easily deformed firmly very much, the place appearance of deformation
Space is easily formed, the gas between the film 5 and the space of a whole page of half tone 4 cannot be discharged, it is preferable that the color of sponge is preferably the depth of extinction
Color such as black, dark-brown, red, easily the reflective light that easily causes is uneven for light color, causes line width uneven, and the sponge plate
The sheet material for selecting surface finer and closely woven, smooth, there are bubble or out-of-flatness in surface can cause the reflection and refraction of light, cause
The thin grid edge of half tone 4 is irregular, line width width is uneven.The size of sponge plate is designed according to screen frame size, and surrounding leaves 1 hand
The distance of finger, the thickness of sponge plate no more than half tone 4 screen frame highly；Hardboard 2 uses metallic plate or glass plate or plastic plate,
The thickness of hardboard 2 is no more than the screen frame of half tone 4 highly, and the screen frame that the total height for vacuumizing servicing unit is more than half tone 4 is high
Spend and be no more than 2 times of screen frame height.
Servicing unit is vacuumized when being exposed for a kind of half tone for more fully understanding the present embodiment, in conjunction with Fig. 3 to this
The use of embodiment is briefly described.When light source exposure is carried out to half tone 4, the film 5 is placed in the upper of the printing surface of half tone 4
Side, and the top of the film 5 fits with exposure machine, this vacuumizes the lower section that servicing unit is placed in the blade face of half tone 4, and soft board 3 is pasted
Tight half tone 4, and four edges of half tone 4 are respectively equipped with a wireway 6, exclude the residual air on exposure machine table top, make net
Version 4 and the film 5 are brought into close contact.Hardboard 2 applies pressure to the top of pad 1, and the bottom of pad 1 passes through work of the soft board 3 to half tone 4
Firmly spread from center to surrounding, then the air between half tone 4 and the film 5 is discharged from center to surrounding diffusion type, exhaust effect
It is splendid.
Additionally, as shown in figure 4, when half tone 4 carries out lower light source exposure, the scraper of half tone 4 faces up, and the film 5 is placed in net
The lower section of the printing surface of version 4, by exposure machine mesa supports, this vacuumizes the scraper that servicing unit is placed in half tone 4 for the lower section of the film 5
The top in face, soft board 3 is adjacent to half tone 4, and four edges of half tone 4 are respectively equipped with a wireway 6.In order to protect on exposure machine
Lid, it is to avoid lid and the directly contact of hardboard 2 on exposure machine, sponge plate 3 is can be set in the top of hardboard 2.
