Rotary table for lens vacuum coating machine

Abstract

The invention relates to a turntable for a vacuum lens coating machine. The vacuum lens coating machine comprises a pushing motor (1), a material trolley (2), one-way pushers (3), an upper support (4), the turntable (5), bearing wheels (6), a rotation stop assembly (7), a base (8), a sprocket chain (9), a rotating motor (10) and a rotating shaft (11). The vacuum lens coating machine is characterized in that the rotation stop assembly (7) is arranged on the rotating shaft (11), the rotating motor (10) is used for driving the turntable (5) to rotate to the 180-degree position through the transmission of the sprocket chain (9), and the one-way pushers (3) on two sides are used for pushing the material trolley (2) to the next station by the simultaneous driving of the pushing motor (1) and the sprocket chain so as to transfer a lens on a coating rack of the vacuum lens coating machine. By adopting the turntable provided by the invention, the consumption of kinetic energy can be saved, the abrasion between related parts can be reduced, the coated lens can be rotated stably in the whole coating process, and the coating quality can be improved further.

Description

technical field [0001] The invention relates to a lens vacuum coating machine Turntable , suitable for use in the coating of spectacle lens coating equipment. Background technique [0002] known The coating frame of the lens vacuum coating machine is composed of a frame, a revolution mechanism and several rotation mechanisms. Since each rotation mechanism has only one plated piece placement rod, only one plated piece can be placed. Therefore, its production efficiency is very low, and the average energy consumption per piece is high, which is difficult to meet the needs of modern scale production. Contents of the invention [0003] In view of the above deficiencies, the object of the present invention is to provide a lens vacuum coating machine Turntable , the rotary table is set on the base through two load-bearing wheels, and the rotating motor drives the rotary table to rotate 180°. It is positioned by hard limit, and the double-sided one-way pusher pushes the mater...
