Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Conventionally, as traditional spraying process is blind spray, during spraying, spraying ink is easy to be sprayed
It is applied to the edge of 3D bend glasses and causes product bad.
In order to solve this technical problem, the present invention proposes a kind of spraying method of 3D glass cover-plates, please refers to Fig.1 to figure
3, for the spraying method for the 3D glass cover-plates that first embodiment of the invention proposes, specific implementation mode includes the following steps：
S101 checks whether the cleanliness factor of spray finishing jig inner cavity meets default cleaning after flush coater is by spraying test
Spend grade.
When testing flush coater, control flush coater sprays out an elliptical region on drawing, then detects
It whether there is particulate matter in the elliptical region.In this respect it is to be noted that when being detected to the elliptical region, can lead to
The mode for crossing machine scans is detected, and is less than default grain using the grain size for the particulate matter that need to only ensure to scan when machine scans
Diameter can prove that the flush coater sprays test passes.As supplement, in order to reduce cost, the side that can also observe by the naked eye
Formula carries out, and when being checked in a manner of macroscopic, bulky grain grain size can not be observed directly as criterion of acceptability using naked eyes.
If not observing particulate matter, confirms that flush coater test passes through, then proceed to check the clean of spray finishing jig interior wall
Cleanliness.It only needs to ensure that the cleanliness factor of spray finishing jig inner cavity reaches default cleaniliness classs.In the present embodiment, corresponding
Default cleaniliness classs is hundred grades namely standard dust particle diameter is more than or equal to 0.5 μm.
S102, if the intracavitary cleanliness factor of spray finishing jig, which meets, presets cleaniliness classs, by 3D glass cover-plates according to default
Modes of emplacement is placed into spray finishing jig.
Further, it after the clean cavity degree for detecting spray finishing jig meets default cleanliness factor standard, can incite somebody to action at this time
Above-mentioned 3D glass cover-plates are placed into spray finishing jig.In the present embodiment, referring to Fig. 2, spray finishing jig includes jig base station
101 and the baffle 102 set on 101 lateral margin of jig base station.As can be seen from Figure 2, the vertical height of baffle 102 is more than jig base
The vertical height of platform 101 is additionally provided with a stage portion 103 in the inside of baffle 102.
Referring to Fig. 3, to 3D glass cover-plates in this present embodiment, including a glass plate body 201 and it is set to the glass
The top of the curved face part 202 of 201 opposite sides of glass plate body, the top surface of the stage portion 103 and the curved face part 202 is located at same
On horizontal plane.Namely above-mentioned stage portion 103 can just block curved face part 202 completely, and spraying ink is prevented to be sprayed onto glass
The lateral margin of plate body 201 ensure that the yield of product.
When actually placing, by the curved face part 202 of 3D glass cover-plates towards the inside of jig base station 101, curved face part 202
Lateral margin and the interior lateral margin of stage portion 103 fit.It should be understood that the setting, which can place spraying ink, is sprayed into 3D glass covers
The lateral margin of plate, to ensure that the yield of product.As supplement, can one rubber be set in the inside of above-mentioned stage portion 103
Circle, to effectively prevent the lateral margin of 3D glass cover-plates to be scratched, reduces the loss in production process.
S103 is injected into flush coater after stirring the first preset time to spraying ink with the first mixing speed with to 3D
Glass cover-plate is sprayed.
Before being sprayed, it is also necessary to modulation spraying ink.In this step, default with the first mixing speed stirring first
Time.Wherein, ranging from 180~270r/min of the first mixing speed, ranging from 22~28min of the first preset time.
In the present embodiment, the first mixing speed is 200r/min, and the first preset time is 25min.After agitated, ensure spraying ink
Range of viscosities, which is 200~400dpa.s, can meet spraying requirement.In the present embodiment, the viscosity for spraying ink is
300dpa.s。
In this respect it is to be noted that the spraying ink selected by the present invention comprising crude oil, diluent, curing agent and
Antifoaming agent.Wherein, the mass percent of crude oil is 45%~55%, and the mass percent of diluent is 23%~25%, solidification
The mass percent of agent is 9%~10%, and the mass percent of antifoaming agent is 11%~13%.In the present embodiment, crude oil
Mass percent is 55%, and the mass percent of diluent is 24%, and the mass percent of curing agent is 10%, the matter of antifoaming agent
It is 11% to measure percentage.
The spraying method of 3D glass cover-plates proposed by the present invention, flush coater test pass through after, spray finishing jig inner cavity it is clean
After cleanliness also complies with purity requirements, then 3D glass cover-plates are placed into according to preset mode in spray finishing jig, due to putting
By the touch surface of 3D glass cover-plates backwards to the inside of spray finishing jig when setting, the lateral margin of 3D glass cover-plates is then sprayed-on jig institute at this time
It blocks, when being sprayed, spraying ink can be effectively prevent to be sprayed into the lateral margin of 3D glass cover-plates.3D glass proposed by the present invention
The spraying method of glass cover board can effectively prevent the lateral margin of 3D glass cover-plates to be contaminated with ink, ensure that reality in spraying process
Spraying process is normally carried out, and improves the yield of product.
Fig. 4 and Fig. 5 are please referred to, second embodiment of the invention also proposes a kind of spraying method of 3D glass cover-plates, specific
Implementation includes the following steps：
S21, flush coater carry out spraying test.
Control flush coater sprays out an elliptical region on drawing, then detects and whether there is in the elliptical region
Particulate matter.When being detected to the elliptical region, can by way of machine scans or the mode that observes by the naked eye into
Row.
S22, spray finishing jig cleanliness factor inspection.
In this step, ensure that the cleanliness factor of spray finishing jig inner cavity reaches default cleaniliness classs.In the present embodiment
In, corresponding default cleaniliness classs is hundred grades namely standard dust particle diameter is more than or equal to 0.5 μm.
3D glass cover-plates are put into spray finishing jig by S23.
