A single crystal silicon rod feeding device for square cutting machine

Abstract

The invention discloses a single crystal silicon rod feeding device for a square cutting machine, which comprises a material storage box and a feeding car, and two ends of the material storage box are respectively provided with a material inlet and a material outlet, and the material storage One end of the box near the discharge port is obliquely provided with a first material guide plate, and the height of the first material guide plate is adapted to the height of the feeding cart, and the feeding cart includes a frame and a material seat connected to the top of the frame , the interior of the material placement seat is provided with a detection device, and the storage box and the detection device are electrically connected to the controller. The invention stores the silicon rods through the material storage box, and feeds the feeding carts one by one, which is helpful to control the feeding speed and frequency. The detection device performs length detection during feeding to realize automatic measurement of the length of the silicon rods. , to determine the geometric center of the silicon rod, to ensure that the clamping mechanism can clamp to the center of the silicon rod, to prevent the unbalanced weight of the silicon rod from slipping and one end tilting, thereby improving the reliability of clamping and cutting quality, and increasing production efficiency .

Description

technical field [0001] The invention relates to the technical field of crystal silicon cutting, in particular to a single crystal silicon rod feeding device for a square cutting machine. Background technique [0002] With the society's attention and openness to the utilization of green and renewable energy, the field of photovoltaic solar power generation has received more and more attention and development. In the field of photovoltaic solar power generation, the usual crystalline silicon solar cells are made on high-quality silicon wafers, which are cut from pulled or cast silicon rods by multi-wire saws. The existing silicon rods are cut Usually, a silicon ingot squarer is used, and the silicon ingot is squared mainly through the cutting line in the equipment in a fast-moving state. When the squarer is in use, the silicon ingot with cutting needs to be transported to the lower part of the clamping mechanism through the feeding device. , The silicon rod is clamped by the ...
