Description
Technical field
It the utility model is related to silkscreen process servicing unit in a kind of solar panel production process, and in particular to
A kind of battery plate surface subparticle blow device.
Background technology
Conventional crystalline silicon solar cell technological process generally includes following processing step:Making herbs into wool → diffusion → etching →
PECVD → silk-screen printing → sintering → test.
In pecvd process section, to pursue higher battery conversion efficiency, tubular type PECVD use is more universal.But in pipe
Formula pecvd process process, silicon chip is often in the more environment of microparticle.The source of these microparticles generally includes following several
Aspect：Caused by hard collision, plasma bombardment process between inserted sheet process silicon chip and graphite boat stuck point silicon chip surface damage,
Ceramic rod damage etc. caused by cold cycling.Handled through pecvd process, part silicon chip surface will be inevitably with a small amount of micro-
Particle, these subparticles the adhesion strength subsequently printed is influenceed it is very big, the printing silk thread and cell panel of unit area it
Between exist more than a threshold value subparticle may result in printing silk thread come off.In follow-up screen printing process, if not pre-
First silicon chip surface residual microparticle is effectively removed, the bad, half tone of printing will be caused to collapse, and version, cell piece are hidden in batches to split etc. one
Series negative effect, so as to cause production yield to decline, manufacturing cost rises.
Removed for silicon chip surface microparticle after PECVD, existing part measure in crystal-silicon solar cell manufacturing, such as
Before feeding, the silicon chip in the gaily decorated basket is purged back and forth using hand-held air gun；Feeding process, install additional and blow directly over silicon chip
Device of air, vertical purging etc. is carried out to silicon chip surface.Nevertheless, there is the drawbacks of obvious in the above method.Using hand-held
Air gun purges, and major drawbacks are：Gun pressure is difficult to ensure that excessive initial air-flow may cause cell piece moment to rupture, and
Too small air-flow is then not enough to effectively remove silicon chip surface microparticle；And manual operation be limited to manual operation proficiency with
And conscientious degree etc., more uncontrollable factors be present, cause follow-up silk-screen printing disqualification rate rise or product use it is durable
Degree reduces.
Also there is the blow device that some researchs disclose mechanization, as Chinese patent CN2016205252376 discloses one
Kind blow device, the device are fixed after solar panel from side to battery plate surface on belt conveyor using vacuum cup
Purged.This Purge methods can remove the larger particles of battery plate surface, and for the small subparticle effect of particle diameter
Unsatisfactory, the ratio surface of subparticle is larger, big with the contact area of cell panel, and surface energy is also bigger than bulky grain, bonds
Power is stronger, and one direction purging is difficult to clean up subparticle.
Also there is multi-direction while blow device such as Chinese patent CN2015205765391, a kind of disclosed three direction is simultaneously
Blow device, the device are used for the purging after printing, and this three direction purges simultaneously, and admission pressure identical device, still
Be the equal of unidirectionally to purge, pressure is finally pooled at three direction wind power balance points, and is conveyed to the small direction of air pressure.If
Before printing, the wind pressure in three directions is identical, assembles to centre, easily causes airborne dust, cause secondary pollution.
The content of the invention
The purpose of this utility model is to provide a kind of three directions and intersects blow device, and the device can improve solar cell
Plate surface subparticle purges clean level.
To achieve these goals, the utility model includes a belt conveyor, and solar energy is placed in belt conveyor upper surface
Cell panel, in addition to sweep module, the sweep module includes two side blow devices and a front blowing device, described
Side blow device includes a left blower device and a right blower device；The left blower device and right blower
The air supply direction of device is parallel with the cross section of belt conveyor, and points to solar panel, and left blower device blows with right side
The air-out direction of wind apparatus is non-intersect；
The front blowing device is located at conveying side's contrary of the top of belt conveyor, its blowing direction and belt conveyor,
And solar panel is pointed to, and it is parallel with fore-and-aft plane where belt conveyor conveying direction；
Also include first compressed air source, the right blower device passes through right side ajutage and the first compressed air

By setting the side blow device of the disjoint left and right sides of blowing direction, solar panel course of conveying
In, subparticle can be cleared up respectively from both direction successively by the horizontal purging wind of both direction.Due to subparticle
Surface is not circle, and its angle between adhesive surface is in different directions and differs, the small one side of angle and adhesion
Surface bonds closer, it is difficult to can increase purging successful probability when purging, but being purged from other directions.
Simultaneously only from side-swept, due to purging limited area, easily the particle at the big position of wind-force is blown to and blown
Get on inswept surface.Therefore by front blow device, the generation of such case can be avoided, further improves cleaning energy
It power, can also increase the purging in a direction, increase cleaning dynamics.
Preferably, the left blower device and the air-out direction of right blower device and the upper surface of solar panel
Angle in the range of 0-10 degree.Air-out direction and the bigger pressure to solar cell plate surface of solar panel angle are just
It is bigger, it is unfavorable for adhering to the purging of stronger subparticle, low-angle purging is easy to separate subparticle and adhesive surface,
And be not easy to dispel particle, second, being advanced along blowing direction, the generation of secondary pollution is prevented while improving cleaning capacity.
Preferably, the angle of the upper surface of the air-out direction of the front blowing device and solar panel is in 0-45 degree
In the range of.
Preferably, the left blower device and right blower device are air knife.Air knife air-out is more concentrated, and cleans ability more
It is excellent.
Further, the front blowing device is combination air knife, and it includes the first air knife of a horizontal blast, one
The second air knife that air supply direction intersects with solar panel, and the wind connected with the first air knife and the second air knife tail end
Room；
An air-flow plate is provided with air compartment, air compartment is separated into two parts up and down by the air-flow plate；
First air knife connects with the bottom of air compartment, and second air knife connects with the top of air compartment；
Respectively there is an air inlet at the both ends of the bottom of air compartment.
This combination, subparticle is tilted by the first air knife, purged subparticle to the energy that gets sample by the second air knife
The other end of cell panel.Work in combination can bring more preferable cleaning effect.
