Background technology:
In the production technology of solar cell, the preparation of suede structure is the important step that increases battery sheet absorptivity.Desirable suede structure helps to improve the performance of battery.Because incident light has increased the absorption of light in the repeatedly reflection and the refraction of silicon chip surface, its reflectivity is very low, is mainly reflected in the raising of short circuit current.The preparation of so-called suede structure is to utilize NaOH dilution, ethylenediamine and chemical mordants such as phosphorus benzenediol water, the monoethanolamine aqueous solution that silicon chip surface is carried out matte to handle, handle the back silicon chip surface and form densely covered pyramid shape tetragonal pyramid, the reflection of incident light rate is reduced in 10%.Making herbs into wool is reflected in the texturing slot to be carried out, because silicon chip and Woolen-making liquid have produced chemical reaction, original chemicals in order to make technology stability stronger, need be replenished corresponding chemicals by reaction consumes in the Woolen-making liquid in Woolen-making liquid after certain reaction times.In order to reduce the number of times of fluid infusion manually, the process of convenient fluid infusion, concentrated liquid supply device must be set, this liquid supply device can a large amount of chemical reagent of disposable storage, in the etching device operation process, according to the design of program, at the appointed time use mechanical pump in texturing slot, quantitatively to replenish chemical reagent.
This texturing slot liquid supply device, as shown in Figure 1, it comprises fluid reservoir 1, woven hose 2, fluid infusion pump 3, unidirectional valve 4, flowmeter 5 and texturing slot 6, fluid reservoir 1 passes through woven hose 2 with fluid infusion pump 3, unidirectional valve 4 and flowmeter 5 are together in series with texturing slot 6, the imbibition end of fluid infusion pump 3 links to each other with the bottom of fluid reservoir 1 by woven hose 2, the outlet end of flowmeter 5 feeds in the texturing slot 6 by woven hose 2, manually the chemical reagent for preparing is joined in the fluid reservoir of being made by the PP material 1, then in the process of etching device operation, at set intervals or after reacting certain number of times, open fluid infusion pump 3, extracting a certain amount of chemical reagent solution from the bottom of fluid reservoir 1 is transported to the texturing slot 6 of etching device by woven hose 2, by the capacity of flowmeter 5 demonstration make-up solution, after reaching predetermined magnitude of recruitment, close fluid infusion pump 3.From add the additional chemical reagent solution for preparing to fluid reservoir 1 after, to replenishing in the process of chemical reagent to texturing slot 6, the chemical reagent solution in the fluid reservoir 1 remains static always.Owing to contain number of chemical article and water in the chemical reagent solution, layering can take place after long-time static, thereby the concentration that has caused the chemical reagent solution of fluid reservoir 1 bottom is higher than the concentration at top, make that the chemical reagent solution concentration of replenishing in the different periods is variant, thereby influenced the stability of process for etching.
The utility model content:
In order to remedy the above deficiency that existing texturing slot liquid supply device exists, the purpose of this utility model provides the device that a kind of texturing slot replenishes the uniform concentration chemical reagent.
The technical scheme that the utility model adopted is:
Described texturing slot replenishes the device of uniform concentration chemical reagent, it comprises fluid reservoir, woven hose, the fluid infusion pump, unidirectional valve, flowmeter and texturing slot, the fluid infusion pump, unidirectional valve and flowmeter are arranged between fluid reservoir and the texturing slot after being connected by woven hose, the liquid sucting port of fluid infusion pump is fed the bottom of fluid reservoir by woven hose, the liquid outlet of flowmeter feeds in the texturing slot through woven hose, it is characterized in that: set up the even circulation circuit of concentration in the fluid reservoir, the even circulation circuit of described concentration is formed by connecting by stirring pump and woven hose, the liquid sucting port that stirs pump reaches the bottom of fluid reservoir by woven hose, and the liquid outlet that stirs pump reaches the upper oral part of fluid reservoir by woven hose.
Its course of work requires: stir pump and fluid infusion pump by the automatically controlled part control in the etching device, pump is stirred in startup earlier in 3～5 minutes before the fluid infusion pump startup, chemical reagent solution in the fluid reservoir is stirred, and then require regularly to start fluid infusion according to process for etching by the fluid infusion pump.
Owing in fluid reservoir, set up the even circulation circuit of concentration, by stirring pump to the homogenizing stir process that constantly circulates of the chemical reagent in the fluid reservoir, make that the solution in the fluid reservoir is evenly not stratified, the concentration of guaranteeing each chemical reagent that replenishes in texturing slot is identical, guarantee that Woolen-making liquid satisfies technological requirement in the texturing slot, thereby improved the stability of process for etching, guaranteed the making herbs into wool quality of silicon chip.
