Abstract

The invention relates to a part of a thin-film solar cell manufacturing device, in particular to an EVA film hob cutting device of a thin-film solar cell. The EVA film hob cutting device comprises a knife rest which is used for installing a cutting knife, wherein the bottom of the knife rest is fixedly connected with a slide block, the slide block is mutually matched and positioned with a fixed linear guide track under the slide block, the slide block and the knife rest can move along the linear guide track, an upper knife shaft, a lower knife shaft and a rubber wheel shaft are arranged on the knife rest, one of the upper knife shaft, the lower knife shaft and the rubber wheel shaft is a driving shaft driven by an electric motor, the other two shafts are synchronously driven by the driving shaft through a driving mechanism, the ends of the same sides of the upper knife shaft and the lower knife shaft are respectively provided with an upper hob and a lower hob which can rotate along the upper knife shaft and the lower knife shaft, the edges of the upper hob and the lower hob are provided with interlaced and bonded parts, at least one rubber rolling wheel is arranged on the rubber wheel shaft, and the bottom of the rubber rolling wheel is pressed on the top surface of the linear guide track. The EVA film hob cutting device can automatically cut an EVA film of a thin-film solar cell and has high automation degree and high machining precision.

Description

technical field [0001] The invention relates to thin-film solar cell manufacturing equipment components, in particular to a thin-film solar cell EVA film hob cutting device. Background technique [0002] In the thin-film solar cell production line, EVA must be cut around to the specified size before laminating and then laminating automatically. At present, the film is mainly used after manual cutting, which is not suitable for automatic production lines, the production efficiency is low, and the dimensional accuracy is difficult to control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thin-film solar cell EVA film hob cutting device capable of automatically cutting the thin-film solar cell EVA film with high degree of automation and high processing precision. [0004] The thin-film solar cell EVA film hob cutting device of the present invention includes a knife holder for installing a cutting tool, the bott...
