Abstract

The utility model discloses a liquid carrying wheel of a PSG cleaning machine. The liquid carrying wheel comprises a plurality of rollers arranged in an etching tank, a plurality of liquid carrying wheels are arranged on each roller, and a plurality of sawtoothed slots are formed in the surfaces of the liquid carrying wheels along the circumferential direction. The liquid carrying wheel has the advantages that the etching evenness is good and the process is easy to adjust: as the liquid carrying type is adopted, the liquid carrying wheel is not influenced by pump flowrate, so that the etching evenness is good and the process flexibility is strong; went without saying, chemical liquid medicine is saved in a liquid carrying type; the etching area can be randomly adjusted without causing influences of excessive etching or under etching, and simultaneously, the widths of the liquid carrying wheels are different, so as to enable the liquid carrying wheels of different specifications to be combined into a combination body with stronger usage property, thus being capable of conducting adjustment according to different product demands, and further being capable of meeting production demand without the need of replacing driving wheels, and having low maintenance cost.

Description

The PSG cleaning machine is taken the liquid wheel

Technical field

The utility model relates to a kind of Wet-method etching device, relates in particular to a kind of PSG cleaning machine and takes the liquid wheel.

Background technology

Now line of solar cells in the industry, the used mode of dephosphorization silex glass etching procedure is: dry etching and wet method quarter.Certainly wet etching is the formula of floating waterborne, and the etching of floating formula on the traditional water exists a lot of problems: 1, cross the phenomenon at quarter; 2. owing to be the formula of floating waterborne, soup consumption is very big; 3. the etching area is big, in arriving alkali groove zone, serious crystalline polamer occurred, blocks air knife, makes battery conversion efficiency on the low side, has to do over again, and causes the waste of resource and doing over again of production.

Summary of the invention

The utility model purpose is for overcoming the deficiency of above-mentioned prior art, providing a kind of PSG cleaning machine to take the liquid wheel.

For realizing above-mentioned purpose, the utility model adopts following technical proposals:

A kind of PSG cleaning machine is taken the liquid wheel, comprises a plurality of rollers that are installed in the etching groove, and a plurality of liquid wheels of taking are installed on each roller, and the surface of taking the liquid wheel is provided with several zig-zag grooves along circumferential direction.

Take liquid wheel endoporus and have inside groove, be equipped with in the inside groove and be fixed on O type circle on the roller taking the liquid wheel.

Through these two kinds of different modes (take liquid wheel carry chemical corrodes the silicon chip back side and form moisture film at the silicon chip diffusingsurface covers), reach battery sheet positive and negative electrode insulating purpose.Take the principle of liquid formula, its method is to be driven by power wheel to take the liquid wheel, takes the liquid wheel chemical liquid that carries is sticked to the silicon chip back side, reaches the purpose of etching.

The PSG cleaning machine is taken the application of liquid wheel: utilize and take the liquid wheel and replace traditional waterborne floating, the main utilization taken the liquid wheel and taken liquid to the silicon chip back side and carry out etching, takes the liquid wheel according to what Demand Design went out different lengths; Its associativity is stronger, is fit to the diversification production of product, can reach the purpose of PSG; Liquid wheel etching is taken in use; It's quarter can avoid to past silicon chip on the one hand, on the other hand, the liquid wheel is taken in use can satisfy the production multiple demands; And the adjustment time be change roller time 1/5, can save greatly because of changing and safeguard the influence that power wheel caused the PT.Therefore, the routine maintenance that the liquid wheel adapts to cleaning machine is fully taken in use.

Our design now take the wheeled etching of liquid, obtained the practical probation of my company now, its principle is exactly with the silicon slice placed transmission in transmission shaft after the diffusion; Diffusingsurface up; And on diffusingsurface, cover with moisture film, reach the purpose of protection diffusingsurface, in silicon chip enters into etched area; Take the liquid wheel and will carry the PN junction disconnected method at quarter that chemical liquid will not spread one side, and that one side of moisture film protection does not receive any destruction.

The beneficial effect of the utility model is that taking the liquid wheel has several big advantages:

Etching homogeneity is good, and technology is prone to adjustment: owing to be to take the liquid formula, do not receive the influence of pumping capacity; Therefore etching homogeneity is good, and the technology retractility is strong, 2. saves chemical liquid; Self-evident, to take the liquid formula and practice thrift soup certainly, 3 etching areas are arbitrarily adjusted; And can not cause quarter or carve obstructed influence, we will take the liquid wheel and be designed to the size that width differs simultaneously, make the liquid wheel of taking of different size be combined into the stronger molectron of usability; Can adjust according to the Different products demand, need not to change power wheel and just can satisfy the production demand thereby reach, maintenance cost is low.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

As shown in Figure 1, a kind of PSG cleaning machine is taken the liquid wheel, comprises a plurality of rollers 1 that are installed in the etching groove, and roller 1 is provided with gear 2, is equipped with 7 on each roller 1 and takes liquid wheel 3, and the surface of taking liquid wheel 3 is provided with several zig-zag grooves 6 along circumferential direction.Take liquid and take turns 3 endoporus and have inside groove, be equipped with in the inside groove and be fixed on O type circle 4 on the roller taking liquid wheel 3.

Taking the liquid wheel makes: be made into part as shown in Figure 1 taking liquid wheel 3; Be installed on the roller 1, take liquid and take turns 3 surfaces and be provided with several zig-zag grooves 6, reach the ability of portability soup through processing; Taking liquid takes turns 3 endoporus and has inside groove; Be used for installing O type circle 4, cooperate in roller through O type circle 4, O type circle 4 is to be used for confirming to take the position of liquid wheel 3 on roller 1.

Principle is exactly that the silicon chip 5 after the diffusion is placed on transmission in the transmission shaft; Diffusingsurface up; And on diffusingsurface, cover with moisture film, reach the purpose of protection diffusingsurface, when silicon chip 5 enters in the etched area; Take liquid wheel 3 and will carry the PN junction disconnected method at quarter that chemical liquid will not spread one side, and that one side of moisture film protection does not receive any destruction.

Precaution:

will take the liquid wheel and be made into the certain specification size according to power wheel length;

The liquid of taking that

will make is taken turns on the power wheel of packing into;

The power wheel that

will install is installed to the cleaning machine internal fixing and shuts form well;

opens cleaning switch, throws the silicon chip experiment slice;

takes out experiment slice; Check, weigh; Inspection square resistance or the like is confirmed to put into production use after errorless.
