Abstract
The utility model discloses a clean device that silicon chip bore box fast, including iron plate and capacity bottle brush to iron plate center be the benchmark, according to the interval design the device's that bears the box size, on iron plate with bear the corresponding position trompil of box baffle, and adoption screw fixation volumetric flask cleaning brush. The beneficial effects of the utility model are that through using the utility model provides a clean device that silicon chip bore box fast has reduced the blue -black point proportion of doing over again that diffusion process arouses because of making herbs into wool.
Description
Technical field
This utility model relates to crystal silicon solar batteries sheet and manufactures field, more particularly to the device of a kind of quick scouring silicon wafer bearing box.
Background technology
In the making herbs into wool operation of crystal silicon solar batteries sheet, former silicon chip is through HF, HNO3��H2After the mix acid liquor corrosion of O, the lower surface of silicon chip has less reflectance, matte size evenly and the degree of depth relative to upper surface, thus adopting making herbs into wool lower surface as diffusingsurface, upper surface diffusingsurface of comparing, cell piece is in hgher efficiency.
Making herbs into wool process adopts blanking in an automated fashion, and silicon chip, through conveyer belt, enters silicon wafer bearing box, and lower surface can contact with Carrier box side, if there is the impurity such as dust, soda acid residual at Carrier box edge, it is easy to contamination is to the lower surface of silicon chip. In diffusing procedure, the high temperature of more than 800 DEG C makes impurity center become defect enrichment place, causes that under sheet resistance exception, soda acid high temperature, corrosion of silicon surface forms Bluepoint, stain extremely, and such abnormal sheet needs isolation to do over again.
Therefore, silicon wafer bearing box needed to clear up at interval of certain time limit, and general method for cleaning is for adopting HF:HCL:H2The mix acid liquor of O=4:1:10 carries out soaking 4H, then washes drying and processing. Its actual cleaning effect is not good, for being attached to the stain on magazine, it is impossible to be fully apparent from; The spot of not thoroughly cleaning on Carrier box, it is easy to form new pollution enriched centres, makes the contamination impurity of the silicon chip after making herbs into wool become abnormal sheet after causing diffusion and does over again, reduce company's factor of merit, add rework cost. Accordingly, it would be desirable to adopt new mode thoroughly to clean Carrier box, reduce the pollution to silicon chip diffusingsurface.
Summary of the invention
The purpose of this utility model is to provide the device of a kind of quick scouring silicon wafer bearing box, reaches thoroughly to clean Carrier box, reduces the pollution to silicon chip diffusingsurface, reduces the purpose of blue-black point rework rate after spreading.
The technical solution that this utility model adopts is: the device of a kind of quick scouring silicon wafer bearing box, including iron plate and volumetric flask cleaning brush, with iron plate center for benchmark, the size of this device of line space design according to Carrier box, position perforate corresponding with Carrier box baffle plate on iron plate, and adopt screw fixed capacity bottle cleaning brush.
The beneficial effects of the utility model are the devices quickly cleaning silicon wafer bearing box by using this utility model to provide, and reduce diffusing procedure and do over again ratio because of blue-black point that making herbs into wool causes.

Detailed description of the invention
Technical scheme this utility model provided below in conjunction with accompanying drawing is described in further detail.
In the present embodiment, as shown in Figure 1, adopt the iron plate of a block length 165cm* width 5cm* thickness 0.3cm, with iron plate center for benchmark, and with shown in Fig. 2 at interval of 0.5cm on iron plate with �� 3mm perforate 9, hole is adopted and is screwed use for laboratory 200ml volumetric flask cleaning brush, make a simple and easy Carrier box cleaner. Adopt this simple and easy Carrier box cleaner to pick ethanol and clean Carrier box groove, by production operators, all silicon wafer bearing boxes are stained with ethanol when making herbs into wool operation is relieved and carry out cleaning operation. Adopt the silicon wafer bearing box manner of cleaning up after improving, HF, HCL, H before comparing2The mode of O mixed liquid dipping clears up silicon wafer bearing box, and the blue-black point that diffusing procedure making herbs into wool is relevant ratio of doing over again is dropped to 0.28% by 0.6%.
