Silicon wafer separation device and silicon wafer loading and unloading system

Abstract

Embodiments of the invention provide a silicon wafer separation device and a silicon wafer loading and unloading system. The silicon wafer separation device may comprise an upper sucker, a lower sucker, a first slider drive motor, a first slider, a first transmission mechanism, a horizontal slide rail, and a first cylinder. The first cylinder drives the upper sucker to move up and down. The lower sucker is fixedly arranged at the lower side of a first silicon wafer conveyor belt. When the silicon wafer separation device sucks up an upper silicon wafer in a silicon wafer group, the first silicon wafer conveyor belt stops running, the upper sucker inhales and adsorbs the upper silicon wafer, the lower sucker inhales and adsorbs a lower silicon wafer, the upper sucker is driven by the first cylinder to move up, and the silicon wafers in the silicon wafer group are separated. After the silicon wafers in the silicon wafer group are separated, the lower sucker stops inhaling, and the lower silicon wafer in the silicon wafer group continues to be conveyed by the first silicon wafer conveyor belt. According to the invention, the upper and lower suckers can absorb silicon wafers to make the silicon wafers separated. As no friction is generated between the upper and lower silicon wafers when the suckers absorb silicon wafers to make the silicon wafers separated, damage to the silicon wafers is avoided.

Description

technical field [0001] The invention relates to the technical field of silicon wafer processing equipment, in particular to a silicon wafer slicing device and a silicon wafer loading and unloading system. Background technique [0002] With the depletion of non-renewable energy sources such as petroleum and coal, new energy sources such as solar energy and wind energy have gained new opportunities for development. [0003] In the production process of silicon wafer cells, it is necessary to separate the stacked silicon wafer groups (that is, quartz wafer groups) back to back, and transfer the separated two silicon wafers to two different conveyor belts. The existing silicon wafer separation technology is equipped with rollers on the conveyor belt that transports the silicon wafer group. The rollers can contact the silicon wafers above the silicon wafer group. The friction generated by the rotation drives the upper silicon wafers to move to another conveyor belt. The silicon ...

Problems solved by technology

[0004] However, in the existing silicon wafer separation technology, during the separation process of the silicon wafer, the upper silicon wafer will slide on the lower silicon wafer when the roller drives the upper silicon wafer to move, and a certain amount of friction will be generated between the two.

Since the silicon wafer is relatively thin, it is easy to break due to friction
