Problems solved by technology

[0002] At present, the transmission track of the sintering furnace adopts metal brackets to support the cells. When the cells pass through the high-temperature zone, the back field reaches the eutectic point, which will cause metal fulcrum marks on the back field and leave aluminum spines on the back field. Affected the quality of the back field

Embodiment Construction

[0014] now combined with figure 1 and 2 The present invention is described in further detail. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, so it only shows the configurations related to the present invention.

[0015] Such as figure 1 and 2 As shown in the figure, a sintering furnace for back field sintering of solar cells includes a cell transmission crawler, and a cell air flow floating device is installed in the high temperature sintering area of ​​the sintering furnace, and the cell air flow floating device is arranged on the cell transmission crawler below. The cell air floatation device includes an air source, an air pipe 1 and an air nozzle 2, the air source and the air nozzle 1 are connected through the air pipe 2, and the air nozzle 1 is installed under the battery sheet transmission track. The gas nozzles 1 are arranged in rows under the battery sheet transmission track...

Abstract

The invention relates to the technical field of a fritting furnace for fritting a back surface field of a solar battery piece. The fritting furnace comprises a battery piece transmission crawler belt; and a battery piece airflow floating device is arranged in a high-temperature fritting area of the fritting furnace additionally, and is arranged below the battery piece transmission crawler belt. In the fritting furnace, the battery piece airflow floating device is arranged below the battery piece transmission crawler belt by utilizing the contrast relation that the gravity of the battery piece is greater than friction generated by transmitting the battery piece, so that the fulcrum bracing force of the battery piece is reduced, the quality of the back surface field of the battery piece can be improved greatly, and the output yield of battery pieces is improved by 30 percent.

Description

technical field [0001] The invention relates to the technical field of a sintering furnace used for back field sintering of solar cells. Background technique [0002] At present, the transmission track of the sintering furnace adopts metal brackets to support the cells. When the cells pass through the high-temperature zone, the back field reaches the eutectic point, which will cause metal fulcrum marks on the back field and leave aluminum spines on the back field. Affected the back field quality. This transmission method needs to be improved to improve the appearance yield of the cell. Contents of the invention [0003] The technical problem to be solved by the present invention is: when the cells are transported in the high temperature zone of the sintering furnace, metal fulcrum marks will be produced in the back field, which will affect the quality of the back field. [0004] The technical solution adopted by the present invention to solve the technical problem is: a ...
