Problems solved by technology

Although the contact between the glass and the woven mesh belt is good in this way, the transmission is convenient; but during the transmission process, there will be relative displacement between the glass substrate and the mesh belt, which is likely to cause scratches on the light-receiving surface of the glass substrate and uneven heating of the upper and lower sides of the glass substrate. , causing the glass to bend, greatly increasing the risk of chipping while reducing product yiel

Abstract

The invention provides a transmission device suitable for a cadmium telluride battery thin-film solar cell thermal process, which comprises a plurality of transmission units. Each transmission unit comprises a plurality of steel belts, a plurality of rolling shafts, a servo motor and a speed reducing mechanism; each rolling shaft is sleeved with the same positions of a plurality of steel belts. Each steel belt is supported by a plurality of rolling shafts, and the rolling shafts drive the steel belts to roll; the rolling shaft is electrically connected with the servo motor, and the servo motoris electrically connected with the speed reducing mechanism; a position sensor is installed in the conveying section, the position of the glass substrate is monitored in real time through an HMI andan observation window, and the position sensor is electrically connected with a servo motor in the conveying section. The position sensors and the observation windows are installed in all the conveying sections of the equipment, the position of the glass substrate is known in real time through the HMI and the observation windows, and workers can conveniently control the glass substrate in real time; the rolling shaft and the steel belt can be well assembled together, the angular travel of the servo motor is completely converted into the linear travel of the steel belt, and the purpose of controlling the glass substrate in real time is achieved.

Description

technical field [0001] The invention relates to the field of solar cell manufacturing, in particular to a transmission device suitable for the thermal process of a cadmium telluride cell thin-film solar cell. Background technique [0002] The transmission of the traditional cadmium telluride thin film solar cell heat treatment equipment mainly relies on the braided mesh belt, and the light-receiving surface of the glass substrate is completely in contact with the braided mesh belt. Although the contact between the glass and the woven mesh belt is good in this way, the transmission is convenient; but during the transmission process, there will be relative displacement between the glass substrate and the mesh belt, which is likely to cause scratches on the light-receiving surface of the glass substrate and uneven heating of the upper and lower sides of the glass substrate. , causing the glass to bend, greatly increasing the risk of fragmentation while reducing product yield. ...
