Blanking device for solar cell production line

Abstract

The invention discloses a blanking device for a solar cell production line. The device comprises a silicon chip conveying unit, an air suction pipe, a manifold distributor, a plurality of manifolds, a manifold support plate, a plurality of vacuum pen type sucking discs, an adjustable air knife, a silicon chip limiting baffle plate and a control unit, wherein the silicon chip conveying unit is used for supporting and conveying silicon chips; the air suction pipe is positioned above the silicon chip conveying unit, and is arranged on the manifold distributor; one end of each manifold is arranged on the manifold distributor, and is in gas communication with the air suction pipe through the manifold distributor; the other end of each manifold passes through the manifold support plate and is fixed on the manifold support plate; each vacuum pen type sucking disc is arranged at the other end of a corresponding manifold and is in gas communication with the corresponding manifold; the adjustable air knife is positioned below the silicon chip conveying unit; the upper surface of the adjustable air knife is provided with a gas discharging hole used for blowing gas upwards; the silicon chip limiting baffle plate is positioned on the downstream of the silicon chip conveying unit along the conveying direction, and moves between a standby position and a blocking position under the driving action of a driving unit; and the control unit is used for controlling the blanking device to collect silicon chips.

Description

technical field [0001] The invention belongs to the field of solar cell process equipment, and in particular relates to a material-cutting device after texturing and etching processes in a solar cell production line. Background technique [0002] Solar cells (photovoltaic cells), as a renewable and environmentally friendly energy source, have attracted widespread attention at home and abroad, and various measures have been introduced to promote the large-scale construction of photovoltaic power plants. At the same time, the production process equipment of solar cells has also developed rapidly. The production capacity of each process equipment is constantly increasing, and the requirements of low fragmentation rate and high yield rate of good products put forward strict requirements on the performance of process equipment. The pick-up and transfer of silicon wafers runs through the whole process of the battery process, and is a key link in the rate of fragmentation and yiel...
