Title:
LARGE-APERTURE OPTICAL LENS MOUNTING DEVICE AND METHOD BASED ON COMBINED MAGNETIC AND VACUUM SUCTION
Document Type and Number:
WIPO Patent Application WO/2023/236409
Kind Code:
A1
Abstract:
A large-aperture optical lens mounting device based on combined magnetic and vacuum suction, the device comprising a support (6), electric motors (3.1, 3.2, 3.3), a magnetic attraction and vacuum suction cup (2), a magnetic base (8), a measuring rod (5), a flexible rope (17), an air pump (1), and a traction lens frame (14) configured for loading an optical lens, wherein both the measuring rod (5) and the flexible rope (17) extend and retract under the drive of the electric motors; the air pump (1) is connected, by means of a steel wire rope (18), to the support at a position corresponding to the middle position of the measuring rod (5); the steel wire rope (18) is connected to a driving mechanism which is used for driving the air pump to move up and down; the magnetic attraction and vacuum suction cup (2) is connected below the air pump (1) by means of an air guide pipeline (19); a flexible gasket (4) is arranged at a cup opening of the magnetic attraction and vacuum suction cup (2); the magnetic base (8) is placed below the magnetic attraction and vacuum suction cup (2) when in use, and the magnetic base (8) comprises a magnetizer housing and a cavity in the magnetizer housing; a strip-shaped magnet (13) is arranged in the cavity, and a strip-shaped magnet rotation control member for controlling the strip-shaped magnet (13) to rotate is arranged on the magnetizer housing; magnetic isolation members are arranged on upper and lower sides of the cavity; a replaceable tray (9) is mounted on the magnetic base; and an annular buffer member (10) is arranged on the surface of the tray (9). The mounting device can enables the mounting of optical lenses with different apertures and profile formes, with a stable and controllable suction, and a little damage to a surface film layer of the optical lens.
