Abstract

The invention discloses a transmission device and a transmission control method. The transmission device is used for roll-to-roll transmission of strip, and the transmission device comprises an unwinding reel, a winding reel, a first guide wheel, a third guide wheel and a second guide wheel, wherein the unwinding reel and the winding reel are placed horizontally, the first guide wheel is connectedwith the unwinding reel, the third guide wheel is connected with the winding reel, and the second guide wheel is located between the first guide wheel and the third guide wheel. An adjustment mechanism is arranged between the first guiding wheel and the second guiding wheel, a buffer mechanism is arranged between the second guide wheel and the third guide wheel, the buffer mechanism and the adjustment mechanism cooperate with each other to realize that the strip keeps constant tension in the transmission process, meanwhile, separate control over unwinding and winding is achieved, and the advantages of simple structure, convenient operation and high stability are achieved.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a transmission device capable of maintaining constant tension and equipped with a buffer mechanism and a transmission control method. Background technique [0002] Roll-to-roll transmission is a high-efficiency, continuous production method that is widely used in the textile, paper and electronics industries. In recent years, as the country proposes energy-saving policies and advocates people to use new energy sources, solar cells have developed rapidly as a new type of environmentally friendly energy. Among them, thin-film solar cells are widely used in solar cells due to their excellent performance, light weight and portability. Automobiles, building roofs, wearable electronic devices and other fields. In the production process of thin-film solar cells, roll-to-roll transmission is required. After this type of film is rolled out from the unwinding shaft, some special-purpos...
