Specific embodiment
In order to which those skilled in the art better understand the technical solution of the utility model, with reference to the accompanying drawing further
Explanation.
Embodiment one, as shown in Figure 1, 2, a kind of structure that can effectively promote the halftone service life, including screen cloth printed patterns area
22, ink surface 6 and printing surface 7, in which: the position contacted on screen painting face 7 with 3 corner of silicon wafer has been pasted with knife position adhesive tape
41 and roll setting position adhesive tape 42, play the scraper cutter position that adhesive tape 41 sticking position in knife position correspond to 6 side of ink surface, roll setting position adhesive tape
42 sticking positions correspond to the scraper roll setting position of 6 side of ink surface.
It plays knife position adhesive tape 41 and roll setting position adhesive tape 42 is all made of PE film, thickness is 25-80 μm, the thickness lower than 25 μm
Degree, can not play wear-resistant effect, if being higher than 80 μm of thickness, easily lead to graphic chamfer frame line and occur not printing or void
It is disconnected, in the present embodiment, plays knife position adhesive tape 41 and roll setting position adhesive tape 42 selects 50 μm of thickness, a knife position adhesive tape 41 is
The rectangle structure of 280cmX4.6cm, the frame that long side is parallel to screen cloth printed patterns area 22 attach, and edge mutual distance is
0.1-20mm, the distance more than 20mm, can still be worn, and can not play protection, if it is less than the distance of 0.1mm, will lead to
Corner location does not print, and the present embodiment uses the distance of 5mm, covers two corners that cutter position side has been corresponded on silicon wafer 3,
It attaches smooth；Roll setting position adhesive tape 42 is two pieces of independent adhesive tape, and shape can be rectangle, and triangle is round or arbitrary more

41 and roll setting position adhesive tape 42, play the scraper cutter position that adhesive tape 41 sticking position in knife position correspond to 6 side of ink surface, roll setting position adhesive tape
42 sticking positions correspond to the scraper roll setting position of 6 side of ink surface, for the position for wearing most serious in actual production process, lead to
Crossing attaching adhesive tape avoids screen cloth from directly rubbing with the corner of silicon wafer 3, increases screen cloth wearability, to play a protective role；Halftone
The angle of the inside of outline border 1 is respectively and fixedly provided with thickness arc filling block 5 identical with halftone outline border 1, can active balance screen cloth scraped
Knife passes to the pulling force of halftone outline border 1 when squeezing, make its stress more evenly, guarantee that it is not likely to produce in the long-term use process
Deformation；Lug 8 is symmetrically fixed on the outside of halftone outline border 1,8 surface of lug is smooth；Silicon wafer 3 is placed on workbench 10, work
Vacuum chuck 9 is also equipped on platform 10；Protective device 12 is further fixed on the outside of halftone outline border 1, protective device 12 includes support rod
13, volute spring 14, roller 15, protective film 16, bar shaped drag hook 17 and buckle 18, the support rod 13 is by being fixedly connected on
On halftone outline border 1, support rod 13 is fixedly connected with one end of volute spring 14, and the other end of volute spring 14 is fixedly connected on rolling
The inner surface of cylinder 15, when roller 15 is rotated by external force, volute spring 14 generates deformation and accumulation of energy, after external force disappears, taper
14 exoergic of spring inverts back roller 15 in situ, and 16 one end of protective film is fixed on 15 outer surface of roller and is wound on roller 15,
16 other end of protective film is fixedly connected with bar shaped drag hook 17, and the length of the protective film 16 can at least should be enclosed around halftone outline border 1 one,
Bar shaped drag hook 17 is driving protective film 16 after the circle of halftone outline border 1 one, and buckle 18 that can be ipsilateral with halftone outline border 1 is located at cooperates shape
At locking.
Further, playing knife position adhesive tape 41 includes cementing layer 401, film layer 402 and cured layer 403, and cementing layer 401 pastes
It is attached between screen cloth non-printing district 21 and film layer 402, adhesive strength, while cementing layer 401 and screen cloth non-printing district can be promoted
It is inert between emulsion on 21, avoid emulsion from destroying because chemical reaction occurs, film layer 402 is PET polyester film, materials
Convenient, cured layer 403 is wear-resistant paint, further enhances wear-resisting property；Playing 41 overall thickness of knife position adhesive tape is 25 μm -80 μm,
Shape is rectangle, should at least cover two corners that cutter position side has been corresponded on silicon wafer 3, plays knife position adhesive tape 41 and screen cloth prints
The distance in map brushing case area 22 is 0.1-20mm.
Further, roll setting position adhesive tape 42 is two pieces of independences and the film for being attached at different location, and every piece of film should be extremely
A corner for corresponding to roll setting position side on silicon wafer 3 is covered less, is cut and is pasted for convenience of operator, can have including three
Angular, rectangle, polygon, round various shapes selection, the structure of every piece of film is and knife position adhesive tape 41 is identical；Roll setting position glue
It is 0.1-10mm that 42 overall thickness of item, which is at a distance from 25 μm -80 μm, with screen cloth printed patterns area 22,.
Further, 10 both ends of workbench are provided with sliding slot 11, and vacuum chuck 9 is slidably mounted in sliding slot 11, very
It is cavity among suction disk 9, can connect to form negative pressure with the vacuum line in workbench 10, lug 8 is sucked.
Its working principle is that:
When printing, scraper advances in ink surface 6 and forms local extruding to screen cloth, when roll setting position is with knife position is played, net
Cloth non-printing district 21 is squeezed to rub with 3 corner of silicon wafer, now by between silicon wafer 3 and printing surface 7, corresponding to roll setting position and playing a knife
Adhesive tape is attached at position, so that screen cloth non-printing district 21 is no longer directly contacted with 3 corner of silicon wafer, is increased its wearability, is promoted work
Service life；When stopping printing, the vacuum feed of break vacuum sucker 9 can easily remove halftone, then pull bar shaped drag hook 17,
Drive protective film 16 after the circle of halftone one, it is fixed with buckle 18, to form protection to temporarily unused halftone, it can avoid particle
Object is fallen into screen cloth aperture, can also be protected emulsion not make moist, not scraped damage, and the life-cycle of halftone is further promoted.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody the principles of the present invention to some variations that some of them part may be made, and belong to the utility model
Protection scope within.
