Description
Technical Field
[0001] The invention relates to the technical field of battery production, and in particular to an automatic liquid replenishing device for texturing a crystalline silicon battery sheet. Background Art
[0002] Polycrystalline silicon wafers are a common solar cell material, composed of polycrystalline silicon grains. Compared with single-crystal silicon wafers, polycrystalline silicon wafers have lower production costs but slightly lower efficiency. Polycrystalline silicon wafers are widely used in the field of solar cells and can convert sunlight into electrical energy. In addition, polycrystalline silicon wafers can also be used to manufacture integrated circuits, photovoltaic modules, solar photovoltaic cells and other fields. The texturing production process of polycrystalline silicon wafers mainly includes the following steps: 1. Cleaning; 2. Etching; 3. Coating photoresist; 4. Exposure; 5. Development; 6. Dry etching; 7. Removal of photoresist; 8. Texturing treatment; 9. Cleaning and quality inspection;
[0003] In the production of polycrystalline silicon wafers, the cleaning process is divided into water washing and acid washing. Water washing uses deionized water to rinse the impurities and residual alkali liquid that have been desorbed on the surface. Acid washing uses an acidic solution to neutralize the residual alkali liquid remaining on the surface of the silicon wafer; hydrochloric acid removes metal ions, HF can remove the surface silica layer on the surface, and form Si-H passivation bonds with the silicon dangling bonds on the surface of the silicon wafer to increase the hydrophobicity of the silicon wafer. The acidic solution neutralizes the residual alkali liquid on the surface of the silicon wafer, which will reduce the acidity of the acidic solution. The acidity reduction requires timely acid replenishment to ensure the acidity level and ensure the pickling effect. The system replenishment acid is directly poured into the acid tank into the acid solution that needs to be replenished. The acid solution is directly poured into the acid tank for replenishment. The acid solution cannot diffuse in time, which will cause differences in acidity at different positions in the acid tank. The acidity difference will cause different pickling effects at different positions of the polycrystalline silicon wafer. Secondly, the dosage of acid solution required for the pickling process of polycrystalline silicon wafers of different specifications is different. The acid solution acidity that is too low or too high will directly affect the pickling effect of the polycrystalline silicon wafer. In view of the above problems, the inventor proposes an automatic liquid replenishment device for crystalline silicon cell texturing to solve the above problems. Summary of the invention

[0052] Working principle: First, the silicon crystal cell group to be pickled is transported to the acid tank 1 through the mechanical arm, so that the acid solution covers the silicon crystal cell group, and at the same time, the No. 3 motor 813 is controlled to be turned on. The driving end of the No. 3 motor 813 rotates through the No. 1 bevel gear 814 and the No. 2 bevel gear 815 to drive the No. 2 rotating shaft 802 to rotate. The No. 2 rotating shaft 802 rotates synchronously through the arc frame 803 and the sliding frame 807. The sliding frame 807 rotates through the fixed column 809 to drive the swing frame 810 to swing back and forth. The swing of the swing frame 810 drives the middle reciprocating rotating shaft 811 to reciprocate.

[0054] The acid solution in the acid tank 1 neutralizes the residual alkali solution remaining on the surface of the silicon wafer to reduce the acidity. When acid replenishment is required, the control is turned on the No. 1 motor 506. The driving end of the No. 1 motor 506 drives the No. 1 rotating shaft 502 to rotate through the pulley transmission group. The rotation of the No. 1 rotating shaft 502 drives the guide plate 503 to rotate.

Under the action of pressure, the first rotating plate 707 is pressed against the water inlet pipe 705 to close the water inlet pipe 705.

The movable disk No. 1 504 moves and drives the guide disk 503 to rotate on the fixed slide frame 501 through the connecting rod 505. By changing the inclination angle of the guide disk 503, the reciprocating movement spacing of the reciprocating slide rod 507 is changed, and then the moving distance of the piston plate 703 is changed.
