Abstract

The invention relates to a turnover device, which is used for turning over a sheet. The turnover device comprises a flap provided with a first side edge, a second flap provided with a second side edge, a pair of first rotating half shafts, a pair of second rotating half shafts, and a pair of rotating bases, wherein the second side edge is hinged with the first side edge; the first pair of rotating half shafts are arranged at two opposite sides of the first flap separately; the centers of the pair of first rotating half shafts are located on the same horizontal line; the pair of second rotating half shafts are arranged at two opposite sides of the second flap separately; the centers of the pair of second rotating half shafts are accommodated into recesses of the pair of rotating shafts separately; and after the turnover device turns over a first angle, the pair of second rotating half shafts are accommodated into the recesses of the pair of rotating bases separately. According to the turnover device, pick-and-place of the sheet and turnover of the sheet are considered, and the sheet surface damage caused by manual turnover of the sheet in the prior art is avoided.

Description

technical field [0001] The invention relates to an overturning device, in particular to an overturning device for quickly overturning large-size sheets. Background technique [0002] As the size of LCD TVs continues to expand, the mainstream size of polarizers is also increasing, with the size rising from 32 inches to 55 and 65 inches. In the production process of the polarizer, the polarizing film surface inspected by each process is different, and the polarizer needs to be constantly turned over. For polarizers with a small size, it is relatively easy to flip them manually, but when the size is extended to 65 inches, it requires two people to cooperate to flip them. However, the surface of the polarizer is smooth, sensitive to pressure, and has strict requirements on surface creases , It is easy to produce artificial defects when manually flipping. Contents of the invention [0003] In order to improve the problems that the above-mentioned large-size sheets are not eas...
