Abstract
The utility model relates to a solar energy half tone convenient to expose evacuation, including frame, silk screen cloth and the wire net cloth of setting in the frame, the junction has a compound region, its characterized in that around silk screen cloth and the wire net cloth: a pair of air guide strips arranged in parallel are adhered to the end face of the composite area; when the evacuation operation, the air of four sides is very fast discharged between film and the wire net cloth, and the four sides are airtight, and middle air can't be discharged, can form the unsettled newton ring in position or bubble, exposes under this kind of condition the operation, and the local linewidth that has newton ring or bubble is little and the thin bars edge slightly presents the cockscomb structure, and disconnected bars and virtual seal appear easily when the half tone is used like this, consequently the utility model discloses both sides are provided with the air guide strip between wire net cloth and film, and support through the air guide strip can avoid the side airtight for film and wire net cloth driving fit department air can fully discharge, and the shaping is accomplished on the half tone to thin grid line, and the tangent line is straight.
Description
Technical Field
The utility model relates to a printing half tone technical field, in particular to solar energy half tone convenient to expose evacuation.
Background
The film figure that generally uses of domestic half tone exposure, the whole precision of film figure can only be controlled at 10um at the highest, the required precision of chromatography half tone 15um, just also very high to the requirement of the vacuum of exposure operation (between the film and the half tone space of a whole page), among the prior art, when the half tone linewidth is accomplished 22um about, easily because of the exhaust is insufficient, lead to half tone lines to appear the sidelight, thin bars region tangent line is glutinous on the half tone, consequently also appeared being used for half tone exposure evacuation's auxiliary device, thereby the process is numerous and diverse when leading to half tone exposure, consequently the utility model develops a solar energy half tone convenient to expose the evacuation to solve the problem that exists among the prior art, through the retrieval, not discover with the utility model discloses same or similar technical scheme.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is: the utility model provides a solar energy half tone convenient to exposure evacuation to solve among the prior art the insufficient problem of exhaust between film and the half tone space of a whole page, solve simultaneously and use the numerous and diverse problem of process behind the auxiliary device.
The technical scheme of the utility model is that: the utility model provides a solar energy half tone convenient to exposure evacuation, includes the frame, sets up silk screen cloth and wire cloth in the frame, the junction has a compound region around silk screen cloth and the wire cloth, paste the air guide strip that has a pair of parallel arrangement on the compound region terminal surface.
Preferably, the composite region is square frame strip type structure, the air guide strip sets up at a pair of parallel composite region up end, and the width is 3 ~ 5mm, and length is greater than the distance between composite region and the air guide strip vertically a pair of inner wall, and length is less than the distance between composite region and the air guide strip vertically a pair of outer wall, and thickness is 38 ~ 42 um.
Preferably, a film is attached to the upper end of the air guide strip.
Preferably, four vertex angles of the frame are respectively provided with an air duct.
Compared with the prior art, the utility model has the advantages that:
when the printing screen is exposed, a film is used, the film needs to be tightly attached to the end face of the steel wire gauze, so that the vacuum pumping operation is needed, but in the traditional vacuum pumping process, during the vacuum pumping operation, the air on the four sides between the film and the steel wire gauze is quickly discharged, the four sides are sealed, the air in the middle cannot be discharged, Newton rings or bubbles with unfixed positions can be formed, when the exposure operation is carried out under the condition, the line width of a place with Newton rings or bubbles is small, and the edge of the fine grid is slightly jagged, so that the broken grid and the virtual printing are easy to appear when the screen plate is used, therefore, the air guide strips are arranged on the two sides between the steel wire mesh cloth and the film, the side edges can be prevented from being sealed through the support of the air guide strips, the air at the sealing position of the film and the steel wire gauze can be fully discharged, the thin grid line is formed on the screen printing plate, and the tangent line is straight.
Drawings
The invention will be further described with reference to the following drawings and examples:
fig. 1 is a schematic view of the structure of the present invention;
FIG. 2 is an end view of the film of the present invention placed on the upper end of the air guide strip;
fig. 3 is a schematic structural view of the film during vacuum pumping of the present invention.
Wherein: 1. the air guide device comprises a frame, 2 parts of a silk screen cloth, 3 parts of a silk screen cloth, 4 parts of a composite area, 5 parts of an air guide strip, 6 parts of a film, 7 parts of an air guide pipe.
Detailed Description
The following detailed description is made in conjunction with specific embodiments of the present invention:
as shown in fig. 1 and 2, a solar energy half tone convenient to expose evacuation, including frame 1, silk screen cloth 2 and the wire cloth 3 of setting in frame 1, silk screen cloth 2 and wire cloth 3 junction all around have a compound region 4, paste on the 4 terminal surfaces of compound region and have a pair of parallel arrangement's air guide strip 5, this air guide strip 5 chooses for use the PE membrane, the laminating of air guide strip 5 upper end is provided with film 6, four apex angle punishments of frame 1 do not are provided with an air duct 7.
The composite region 4 is a square frame strip structure, the air guide strip 5 is arranged on the upper end surfaces of the composite regions 4 which are parallel to each other, the width of the air guide strip is 3-5 mm, the length of the air guide strip is greater than the distance between the composite regions 4 and a pair of inner walls which are perpendicular to the air guide strip 5, the length of the air guide strip is less than the distance between the composite regions 4 and a pair of outer walls which are perpendicular to the air guide strip 5, and the thickness of the air guide strip is 38.
The preparation principle of the solar screen plate during exposure is as follows:
