Multipath stirrer for aluminum paste packaging tanks

Abstract

The invention relates to a multipath stirrer for aluminum paste packaging tanks. The multipath stirrer comprises a bottom plate, a driving motor, a transmission box, a fixed plate and rotary shafts, wherein the transmission box and the fixed plate are respectively fixed at two ends of the bottom plate; the fixed plate is connected with the transmission box through the rotary shafts; a plurality of first belt wheels, pressing wheels, a second belt wheel and a regulating wheel are arranged in the transmission box; the driving motor drives the second belt wheel to rotate; the rotary shafts are parallel to one another; the distance between each two adjacent rotary shafts is equal; an interval between the inner sides of the two adjacent rotary shafts is smaller than the diameter of each aluminum paste packaging tank. The multipath stirrer for the aluminum paste packaging tanks has the advantages that a plurality of groups of aluminum paste packaging tanks can be placed between the two adjacent rotary shafts; a large number of aluminum paste packaging tanks can be stirred during once processing; the processing efficiency is greatly improved; in the stirring process, the aluminum paste packaging tanks do not need to be opened; the phenomenon of waste caused by scattering of aluminum paste out of the tanks is avoided, and the phenomenon of oxidation caused by exposing of the aluminum paste in air during stirring is avoided.

Description

technical field [0001] The invention relates to a liquid stirring device, in particular to a multi-channel mixer for aluminum paste packaging tanks in the production of solar cells. Background technique [0002] Solar cells are a kind of clean and environmentally friendly renewable energy. In order to output the electric energy obtained by the photoelectric conversion of the cells, it is necessary to make positive and negative electrodes on the cells. This is the material that forms a close ohmic contact with the P-N junction of the cell. Customarily, the electrode fabricated on the illuminated surface of the battery is called the upper electrode, and the electrode fabricated on the back of the battery is called the lower electrode or the back electrode. The upper electrode is usually made into a narrow grid line, which is beneficial to the collection of photo-generated current and makes the cell have a larger light-receiving area. The lower electrode covers all or most of ...

Problems solved by technology

Although this stirring method can achieve the purpose of stirring the aluminum slurry evenly, it can only stir one tank at a time, and after the stirring is completed, the mixer must be removed from the aluminum slurry tank. The aluminum paste on the surface will be scattered on the ground, which not only pollutes the production site, but also wastes the aluminum paste, and the operation is more cumbersome
