A roll changing apparatus, a winding device and a gluing device. The roll changing apparatus comprises: an unwinding assembly (10), which comprises first unwinding mechanism (11) and a second unwinding mechanism (12); a roll changing assembly, which comprises a mounting base (21), a first adsorption mechanism (22), a second adsorption mechanism (23) and a cutting mechanism (24). The first adsorption mechanism (22) comprises a first adsorption base (221), and the second adsorption mechanism (23) comprises a second adsorption base (231); the first adsorption base (221) and the second adsorption base (231) are arranged along a first direction and are configured such that at least one thereamong may approach relative to the other or be away from one another in the first direction; a side of the first adsorption base (221) facing the second adsorption base (231) is provided with a first adsorption area (2211) and a second adsorption area (2212) which are arranged along a second direction which is perpendicular to the first direction; the first adsorption area (2211) is used for adsorbing a first material belt, and the second adsorption area (2212) is used for adsorbing a second material belt; and the cutting mechanism (24) is used for cutting off the first material belt between the second adsorption mechanism (23) and the first adsorption area (2211) or the second material belt between the second adsorption mechanism (23) and the second adsorption area (2212). Automatic switching of a first material belt and a second material belt may be achieved, which greatly reduces downtime and improves production efficiency compared with a manual roll changing method.

A rewinding system includes a rewinding apparatus for winding a manufactured thin-film tape on a re-winding roll; a loading apparatus for loading the re-winding roll on which the thin-film tape is rewound; and a cutting apparatus for cutting the thin-film tape. The rewinding apparatus includes first and second mounting members in which re-winding rolls are inserted; and a connecting member connected to an end of each of the first and second mounting members to move the first and second mounting members. The first mounting member rotates around a shaft thereof, the second mounting member rotates around a shaft thereof, and the connecting member rotates the first and second mounting members to change positions of the first and second mounting members, and moves at least one of the first and second mounting members to the place where the loading apparatus is arranged.
