Abstract
The utility model relates to frame developing machine equipment for a large screen. The frame developing machine equipment comprises a screen, a vacuum pump and an exposure lamp, as well as an air exhaust joint wherein a negative film is attached to the screen; the binding face of the screen is coated with a photosensitive adhesive layer; the exposure lamp is arranged on the front side of the screen, irradiates the negative film and allows the light to reach the photosensitive adhesive layer of the screen so as to finish exposure; an opening is formed in the negative film; the air exhaust joint is connected to the opening and is connected with the vacuum pump through a connecting pipeline; a gap between the negative film and the screen is vacuumized, so that the negative film is clung to the screen. Compared with the prior art, the frame developing machine equipment has the advantages that the screen does not need to be arranged in a frame developing machine box, so that the size of the manufactured screen is not limited by equipment and space, the light directly irradiates to the photosensitive adhesive, and glass dirt and scratch and distortion of pattern exposure caused by reflection and refraction caused by light irradiation of the glass are avoided, so that the screen quality is improved.
Description
Technical field
The utility model relates to a kind of exposure printing down equipment, especially relates to a kind of large half tone exposure printing down equipment.
Background technology
Half tone exposure sources all adopts printer both at home and abroad so far, formed by face glass (thickness 10～18mm), upper cover plate rubber duck, ultraviolet exposure lamp, vacuum pump, hydraulic mandril, time shutter controller etc., half tone need to be placed in printer, start vacuum pump, air in upper cover plate rubber duck is extracted out, reach certain vacuum tightness the egative film that will expose is adjacent on face glass, then row exposure, printing down completed.
For large half tone, as frame size is greater than the printing screen plate of 4000*3000, printing down equipment size is minimum is 4500*3500, and equipment occupation space is large, and equipment investment expense is high.The space that printing down equipment need to be bled is large, and the time of bleeding is long, upper cover plate rubber duck, the fragile gas leakage of O-ring seal, and vacustat is difficult to ensure.When exposure, light reflects, is refracted to egative film by face glass and finally arrives photosensitive layer on half tone, completes exposure, and the tightening degree of dirty, scuffing on glass, egative film and glass, all will directly affect the printing down quality of half tone.
Utility model content
The purpose of this utility model is exactly to provide in order to overcome the defect that above-mentioned prior art exists the large half tone exposure printing down equipment that a kind of size is unrestricted, improve half tone quality.
The purpose of this utility model can be achieved through the following technical solutions:
Exposure printing down equipment for a kind of large half tone, comprises half tone, vacuum pump, exposure lamp,
On described half tone, be fitted with egative film, on the binding face of half tone, be coated with photosensitive layer,
Described exposure lamp is located at the front of half tone, and egative film is irradiated and reaches photosensitive layer on half tone to complete exposure,
Also comprise an air extraction connector, described egative film is provided with perforate, and air extraction connector is connected to this tapping, and air extraction connector is connected with vacuum pump through connecting tube, and the gap between egative film and half tone is vacuumized egative film is fitted tightly on half tone.
Described air extraction connector is made up of connector and chassis, described connector is connected with vacuum pump through connecting tube, on described chassis, offer evacuation passageway and absorption vacuum passage, described evacuation passageway is communicated with connector, described absorption vacuum passage is provided with and opens and closes mouth, controls the vacuum tightness of air extraction connector.
Described evacuation passageway is funnel-shaped structure, and the bottom surface that one end that diameter is larger is arranged on chassis contacts with egative film, and one end that diameter is less is communicated with connector.
Described absorption vacuum passage is ring texture, is arranged on the outside of evacuation passageway, and is communicated with the keying mouth that is arranged on connector sidepiece.
The edge of described egative film through tape-stripping on half tone.
Compared with prior art, the utlity model has following advantage:
(1) do not need half tone to be placed in printer casing, thereby the half tone size of making is not subject to the restriction in equipment and space all right cost saving;
(2) because shining directly into egative film, light arrives on photoresists, save between original egative film and light across a face glass, avoid that glass is dirty, the reflection that scuffing and irradiation glass produce, the distortion that refraction produces pattern exposure, thereby improve half tone quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the main TV structure schematic diagram of air extraction connector;
Fig. 3 is the structural representation of air extraction connector.
In figure, 1 be half tone, 2 for egative film, 3 for vacuum pump, 4 for connecting tube, 5 for exposure lamp, 6 for air extraction connector, 61 for absorption vacuum passage, 62 for evacuation passageway, 63 for connector, 64 for absorption vacuum passage open and close mouthful.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
Exposure printing down equipment for a kind of large half tone, its structure as shown in Figure 1, comprises half tone 1, vacuum pump 3, exposure lamp 5 and air extraction connector 6.On half tone 1, be fitted with egative film 2, the edge of egative film 2 through tape-stripping on half tone 1.On the binding face of half tone 1, be coated with photosensitive layer, exposure lamp 5 is located at the front of half tone 1, and egative film 2 is irradiated and reaches photosensitive layer on half tone 1 to complete exposure.On egative film 2, be provided with perforate, air extraction connector 6 is connected to this tapping, and air extraction connector 6 is connected with vacuum pump 3 through connecting tube 4, and the gap between egative film 2 and half tone 1 is vacuumized egative film 2 is fitted tightly on half tone 1.The structure of air extraction connector 6 as Figure 2-3, formed by connector 63 and chassis, connector 63 is connected with vacuum pump 3 through connecting tube 4, on chassis, offer evacuation passageway 62 and absorption vacuum passage 61, evacuation passageway 62 is funnel-shaped structure, the bottom surface that one end that diameter is larger is arranged on chassis contacts with egative film, one end that diameter is less is communicated with connector 63, absorption vacuum passage 61 is ring texture, be arranged on the outside of evacuation passageway 62, and be communicated with the absorption vacuum passage keying mouth 64 that is arranged on connector 63 sidepieces.
The utility model can be saved bulky printing down equipment, and save space, investment cost, special large half tone do not have printer can make yet, and can also reduce in addition the space of bleeding, avoid gas leakage without rubber duck, O-ring seal.Can avoid because glass is dirty, scratch the half tone quality problems that cause without face glass.
