Abstract

The invention discloses a lifting device for an upper platform of an automatic layout machine for photovoltaic cell strings. The lifting device comprises a rack, the upper platform, a lifting device and corner chains, wherein a bearing seat and a lower corner chain seat are arranged on four corners of the rack respectively; a guide wheel and an upper corner chain seat are arranged on four corners of the upper platform respectively; transmission shafts of the lifting device are arranged in the bearing seats of the rack respectively in parallel, and lifting cams are arranged on four end heads of the transmission shafts; and the upper platform is arranged above the rack and the guide wheels contact with the lifting cams. According to the invention, a lifting movement of the upper platform is driven by virtue of the lifting cams, thus a tail-end inertia force of the upper platform during an ascending movement is buffered; and longitudinal or transversal swinging of the upper platform during the ascending movement is restrained, and the position accuracy of glass on the platform is effectively ensured by virtue of corner chain mechanisms which are symmetrically arranged in pairs along the diagonal line of the rack, thus product quality is stabilized and improved.

Description

technical field

[0001] The invention relates to the technical field of photovoltaic cell string manufacturing, in particular to a lifting device for an upper platform of a photovoltaic cell string automatic typesetting machine. Background technique

[0002] In the production process of photovoltaic cells, first of all, several unit cells must be arranged into battery strings, and then the battery strings are accurately laid out on the glass covered with EVA paper. In order to ensure that the arrangement of each version of battery strings is consistent, the platform is required to be stable. The glass should be lifted up smoothly, and the hovering position of the platform must be kept at the same position each time. After the battery strings are laid out, the glass is moved out of the glass-carrying platform and connected with other equipment, and the positioning device of the platform must not block the direction of the glass. Channels for conveying to other stations. In th...
