A sheet processing device is configured to separate a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at one end as a bonding portion of the two-ply sheet. The sheet processing device includes a first sheet feeder configured to feed the two-ply sheet, a second sheet feeder configured to feed an inner sheet to be inserted between the two sheets of the two-ply sheet in a state in which the non-bonding portion of the two-ply sheet is separated, and circuitry configured to cause the first sheet feeder to feed the two-ply sheet, perform a sheet separating operation on the two-ply sheet to separate the non-bonding portion of the two-ply sheet, and cause the second sheet feeder to start feeding the inner sheet before completion of the sheet separating operation on the two-ply sheet.

An apparatus for manufacturing a display device and a method for manufacturing a display device. The apparatus for manufacturing a display device includes a frame; a guide member installed on the frame; a clamp including a pair of clamp members installed on the guide member; and a rotation unit configured to rotate the frame to change a relative position of each clamp member with respect to the frame. The clamp member includes a suction member.

A panel alignment apparatus for easily aligning a rectangular panel and preventing damage to an optical film during alignment, where the optical film is bonded to the panel such that one or more sides of the optical film protrude from the panel.

A lamination apparatus, system, and method. The apparatus, system and method are for a lamination press for laminating at least one laminating film to a subject, which may include: an upper press comprising a gel plate, an upper vacuum chamber, and tooling suitable to apply the laminating film; a lower press suitable to maintain the subject to receive the laminating film, and comprising a lower vacuum chamber, an air bearing stage, and servo-positioned tooling; and an aligner that applies the servo-positioned tooling to maintain positional balance and alignment of the subject by the air bearing stage during the laminating while enabling vertical flexure of the lower press, wherein the positional balance and alignment is substantially continuously monitored by a controller.

An apparatus for manufacturing a display device and a method for manufacturing a display device. The apparatus for manufacturing a display device includes a frame; a guide member installed on the frame; a clamp including a pair of clamp members installed on the guide member; and a rotation unit configured to rotate the frame to change a relative position of each clamp member with respect to the frame. The clamp member includes a suction member.

A laminating device adapted for laminating a curved cover plate and a flexible screen. The laminating device includes at least one elastic support assembly and a flexible supporting board for supporting the flexible screen. The flexible supporting board includes a top wall having a central spine portion and loading portions; The elastic support assembly is deformable so that the flexible supporting board can be deformed from a first state to a second state under a pressing effect of the curved cover plate; in the first state, the flexible supporting board is in a shape of a ridge and one of the loading portions is obliquely connected between the central spine portion and one of the side walls, so that in the process of the flexible supporting board being deformed from the first state to the second state, the inclination of the loading portion gradually decreases.

A bonding method for bonding a first substrate to a second substrate includes fixing the first substrate to a first surface of a first bonding chuck and fixing the second substrate to a second surface of a second bonding chuck, the second surface facing the first surface; aligning the second bonding chuck above the first bonding chuck in a vertical direction or in a horizontal direction; bonding the first substrate to the second substrate to make a bonded substrate; and wherein, in the bonding the first substrate to the second substrate, injecting a process gas between the first substrate and the second substrate using a process gas injector surrounding at least one selected from the first bonding chuck and the second bonding chuck in a plan view and injecting an air curtain forming gas to form an air curtain surrounding the first substrate and the second substrate using an air curtain generator are performed in combination.

A lamination device is disposed downstream of a conveying device configured to convey a plurality of electrode bodies, and laminates the plurality of electrode bodies. The lamination device includes: a mounting plate on which the plurality of electrode bodies are laminated, the mounting plate being inclined with respect to the electrode bodies being conveyed by the conveying device; a first wall erected on the mounting plate and perpendicular to a conveying direction; and a drop prevention portion provided on the first wall or on a wall different from the first wall, the drop prevention portion preventing the plurality of electrode bodies from dropping from the mounting plate.
