Abstract

The invention discloses a correction mechanism on silicon wafer etching equipment, and relates to the technical field of silicon wafer production equipment. The correction mechanism comprises a base,a supporting seat, a conveying roller, a driving device, a conveying belt, a slide holder, a sliding seat, a correction mechanism and a guide wheel. The passive part of the correction mechanism is pushed by the trigger plate of the slide holder; a first gear with the diameter smaller than that of a rotating column is driven to rotate under transmission teeth on the rotating column (according to the transmission ratio principle in a mechanical transmission system, the rotating angle of the first gear equivalent to a small gear is larger than that of the rotating column equivalent to a large gear); the guide wheel is driven by the rotating part connected with the first gear to move in the arc direction from front to back along the arc end face of the silicon wafer, and front-back and left-right position correction of the silicon wafer is achieved. Besides, a second gear rotates along connecting teeth under the rotation of the rotating part, so that the guide wheel is driven to rotate. The static friction between the guide wheel and the silicon wafer is changed into dynamic friction, and the abrasion damage of the guide wheel to the silicon wafer is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of silicon wafer production equipment, in particular to a correction mechanism on silicon wafer etching equipment. Background technique [0002] As the photovoltaic industry has attracted more and more attention, the production equipment of solar cells has also developed rapidly. [0003] At present, silicon wafer transmission and correction mechanisms are generally used in equipment such as solar wafer loading and unloading machines, loading machines, etching equipment, and silicon wafer transmission devices. There are two types of existing silicon wafer transmission and correction mechanisms. It is a fixed correction mechanism, which fixes wedge-shaped guide strips on both sides of the silicon wafer transmission line to guide the silicon wafer transmission. The other is a dynamic correction mechanism, that is, the cylinder controls the guide bar to push the silicon wafer to correct the position of the sil...
