Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery piece inter-process transfer, in particular to a battery piece inter-process transfer method. BACKGROUND

[0002] As an important component of solar cells, silicon wafers need to be used in the production of photovoltaic cell silicon wafers. The wafer inserting machine is used to insert the battery silicon wafer into the basket one by one, so as to better store and process the battery silicon wafer. In the whole process of silicon battery manufacturing, the surface cleanliness of the silicon wafer during transportation plays a crucial role. If the silicon wafer surface is contaminated with impurities during storage, the residual impurities are easy to diffuse into the silicon wafer under the subsequent high-temperature process environment, causing defects and a large number of silicon wafers that need to be reworked. Even if some defective silicon wafers remove the surface defects through subsequent wet processing, the internal defects may still cause abnormal electroluminescence characteristics and electrical properties.

[0003] The existing Chinese patent with publication number CN116995010B includes: a conveying mechanism mounted on a chassis for conveying battery silicon wafers; a basket for inserting battery silicon wafers; a lifting mechanism for sequentially lifting the basket; a speed reduction mechanism arranged in the basket for reducing the speed of the battery silicon wafers; the conveying mechanism conveys the battery silicon wafers into the insertion basket, and the speed reduction mechanism reduces the speed of the battery silicon wafers during the insertion process, so that the speed of the battery silicon wafers stops when they are completely inserted into the insertion basket.

[0004] The above device, when in use, has a speed reduction mechanism inside the basket. The battery silicon wafers come into contact with the speed reduction mechanism during the insertion process. The speed reduction mechanism reduces the speed of the battery silicon wafers, so that the speed of the battery silicon wafers stops when they are completely inserted into the insertion slot. This avoids collisions between the battery silicon wafers and the inner wall of the insertion slot, achieving the purpose of protecting the battery silicon wafers. However, in actual use, since the battery silicon wafers are inserted horizontally during the insertion process, and the battery silicon wafers inside the basket are in a horizontal state, the contact area between the gravity and the contamination of the battery silicon wafers inside the basket during the transfer process is large, which easily causes contamination of the battery silicon wafers by particulate foreign matter. This affects the yield of the finished battery silicon wafers, so it is difficult to adjust the battery silicon wafers inside the basket to a vertical carrying posture during the transfer process.

[0005] Therefore, we propose a battery piece inter-process transfer method. SUMMARY
