Solar silicon wafer preheating device

Abstract

The invention discloses a solar silicon wafer preheating device. The device comprises an outer box and a motor, wherein a heat dissipation opening is formed in the front face of the bottom of the outer box; rollers are mounted on the left side and the right side of the heat dissipation opening; a heat insulation box is mounted above the heat dissipation opening; a protective door is arranged on the front face of the heat insulation box; sliding blocks are mounted at the upper end and the lower end of the protective door; a magnet sheet is arranged on the side, close to the vertical center lineof the outer box, of the protection door; the sliding blocks are fixedly connected with the protective door; a rotating shaft is arranged at the upper end of the motor; the motor is located in the heat insulation box; a supporting table is installed above the rotating shaft; a carrier is arranged above the supporting table; the rotating shaft is in threaded connection with the supporting table; clamping plates are installed on the left side and the right side of the carrier; and springs are arranged on the front face of the carrier. The solar silicon wafer preheating device is provided with atoggle clip and the motor, silicon wafers with different thicknesses can be fixed, the silicon wafers are prevented from being abraded, and the device facilitates uniform heating of the silicon wafers.

Description

technical field [0001] The invention relates to the technical field of solar silicon chip preheating devices, in particular to a solar silicon chip preheating device. Background technique [0002] Solar energy is produced by the hydrogen-helium fusion of hydrogen atoms inside the sun and releases huge nuclear energy. The radiant energy from the sun is mainly manifested as the sun's rays, which are often used to generate electricity or provide energy for water heaters in modern times. Silicon wafers are solar energy. The carrier of the cell, the quality of the silicon chip directly determines the conversion efficiency of the solar cell. When the silicon chip is used to make a solar cell, it needs to be preheated by a preheating device to remove the silicon chip. Moisture on the surface is also convenient for detection of silicon wafers. [0003] Modern silicon wafer preheating devices cannot fix silicon wafers of different thicknesses, making it easy to wear the silicon wafe...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a solar silicon chip preheating device to solve the problem that the modern silicon chip preheating device proposed in the above-mentioned background technology cannot fix silicon chips of different thicknesses, so that it is easy to be damaged by the preheating device during preheating. The vibration of the silicon wafer causes the wear of the silicon wafer, and the two sides of the silicon wafer cannot be heated evenly, which affects the quality of the preheating.
