Abstract:
A curved display panel bonding apparatus, used for bonding a display substrate and a cover plate, and comprising: a work platform (1) and a roller assembly (2), the work platform (1) being used for supporting the cover plate; the roller assembly (2) comprises: a bonding roller (21) used for rolling and pressing the display panel and cover plate to be bonded to form a curved display panel and at least one layer of side support roller groups (22) arranged on the side of the bonding roller (21) furthest from the working platform, and each layer of side support roller groups (22) comprising at least one support roller (221), ensuring a greater bonding pressure during the bonding process and also ensuring that the diameter of the bonding roller (21) is small, improving pressure uniformity during the bonding process, and avoiding the problem of black spots or other poor display on the display screen due to uneven bonding pressure distribution.
