Problems solved by technology

[0003] In the normal production process, since silicon wafer sintering will produce oil stains, oil stains will also accumulate on the furnace belt. After printing, silicon wafers will produce oil stains when they contact the furnace belt, which will lead to the degradation of the cells and cause losses. Therefore, the sintering furnace Belt needs to be cleaned periodically
However, the cleaning process is time-consuming and laborious, and production needs to be stopped during cleaning, which greatly affects the production capacity

Abstract

The invention discloses a cleaning device for a furnace zone of a sintering furnace. The cleaning device comprises a box body, wherein the interior of the box body is hollow; through holes used for the furnace zone to penetrate through are formed in the two ends of the box body; heating pipes and fans are arranged in the box body; and the heating pipes and the fans are located below the portion, penetrating through the box body, of the furnace zone. According to the cleaning device for the furnace zone of the sintering furnace, the furnace zone can be cleaned without stopping production, time,labor and cost are greatly saved, and the cleaning device has a great effect on improving the A-grade product rate of battery pieces.

Description

Technical field: [0001] The invention relates to the field of solar cells, in particular to a cleaning device for a belt of a sintering furnace. Background technique: [0002] Sintering is an inseparable part of the screen printing process in the production process of solar cells. The quality of sintering also directly affects the quality of screen printing. Under the action of the ohmic contact with the silicon wafer, the open circuit voltage and fill factor of the solar cell can be improved. At the same time, the high temperature in the sintering furnace can promote the H produced in the coating process to diffuse into the battery, which has a good passive effect on the solar cell. to improve the conversion efficiency of solar cells. [0003] In the normal production process, since silicon wafer sintering will produce oil stains, oil stains will also accumulate on the furnace belt. After printing, silicon wafers will produce oil stains when they contact the furnace belt, ...
