Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its attached drawing.
As shown in Figure 1 to Figure 2, a kind of screen-tensioning machine, it includes stage body 1 and multiple Individual gripper steel on stage body 1
The folder net device 2 of silk screen.Folder net device 2 includes being fixed on the fixed plate 3 on stage body 1, the linear drives in fixed plate 3
Mechanism 4, the sliding panel 5 being slidably connected with fixed plate 3, the quick-speed jigs 6 on sliding panel 5 and it is separately positioned on cunning
First clamping plate 7 and second clamping plate 8 on movable plate 5 and quick-speed jigs 6.
Sliding panel 5 is connected with the driving head of straight line driving mechanism 4, driven by straight line driving mechanism 4 it is for linear motion, with adjust
Save position of the sliding panel 5 in fixed plate 3.Straight line driving mechanism 4 can select the standard components such as electric cylinders, electric push rod.For just
Slided in sliding panel 5 in fixed plate 3, slide (not shown) can also be set between them.
8 mutual cooperation clamping steel wire net of first clamping plate 7 and second clamping plate, quick-speed jigs 6 belong to standard component, it drives second
Clamping plate 8 is mutually clamped with first clamping plate 7.
Multiple folder net devices 2 are at least provided with two adjacent sides in stage body 1, the quantity of folder net device 2 is more, is more easy to
Fine setting to steel wire local modified areas, it is also higher to the Adjustment precision of steel wire.In the present embodiment, 1 four side of stage body is equal
Multiple folder net devices 2 are provided with, if it find that steel wire locally deforms in use, need to only finely tune and clamp the region steel wire
Folder net device 2, be allowed to precision and reach requirement.
As shown in figure 3, a kind of high-accuracy method of throwing the net for the secondary printing halftone that above-mentioned screen-tensioning machine can be used to carry out, successively
Carry out：Net, Imaging Study, sizing, gluing and off line are pressed from both sides, is comprised the following steps that：
Step 1, presss from both sides net：Using screen-tensioning machine, fixation is clamped on four side of steel wire, four sides stretch out at the same time tightens, and reaches
Moderate tension force, and keep the balance of steel wire latitude and longitude direction tension force；
Step 2, local correction：Taken pictures scanning by high-velocity scanning camera, find out the region of steel wire flexural deformation, into
Row local directed complete set amendment, to reach the required precision of secondary printing；
Step 3, sizing：Revised steel wire, carries out heat treatment, prevents steel wire to be again deformed immediately；
Step 4, gluing：Steel wire after heat treatment, is adhered on screen frame with glue；
Step 5, it is off line：The unnecessary steel wire of screen frame surrounding is prescinded, retains the stereotyped screen cloth in screen frame.
In step 1, four sides of steel wire are clamped by the folder net device 2 of screen-tensioning machine, it is then same to four sides of steel wire
Shi Jinhang is stretched, and the tension force of steel wire latitude and longitude can be made more to balance, so as to improve the precision of steel wire, the preferred tension value
For 24N/CM.
In step 2, taken pictures scanning by high-velocity scanning camera, find out the region of steel wire local deformation, then correspond to
Adjustment clamps the folder net device 2 in the region, the region of steel wire local deformation is stretched or loosened etc. and adjusts again, can be into one
Step improves the precision of steel wire.High speed camera is taken pictures after scanning, can be judged by tracking cross steel wire latitude and longitude whether
Flexural deformation, compared to visually observing more accurately and conveniently.
In step 3, heat treatment is by spraying glue, shaping after dry, the steel wire after sizing is not easy again
Deformation, can keep very high precision.
Above-mentioned technique of throwing the net is thrown the net (also referred to as without net netting version) applied to right angle, relative to common oblique knitmesh, its grid line
Can be made thinner, common oblique knitmesh grid line width at 25-30 μm, and right angle throw the net technique grid line at 20 μm or so.
The screen-tensioning machine of the present invention is by setting multiple mutually independent folder net devices so that can be to steel wire when throwing the net
Regional area be finely adjusted, greatly improve photovoltaic printing when printing precision, increase the depth-width ratio of thin grid line, do not increasing slurry
While material list consumes, transfer efficiency is lifted, efficiency will lift 0.1% to 0.2%, and effectively lifting photoelectric conversion efficiency and halftone makes
Use the service life.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, should be covered by the protection scope of the present invention.
