Abstract

The invention discloses a machining method for an anti-deformation TAC lens. The machining method comprises the following steps that S1, an anti-deformation processing device is provided and comprises an upper pressing die and a lower pressing die matched with the upper pressing die, the upper pressing die is of an arc-shaped protruding structure and internally provided with a heating device or a cooling device, and the lower pressing die is of an arc-shaped groove structure and internally provided with a heating device or a cooling device; S2, a bent and formed TAC lens is provided and arranged on the lower pressing die; and S3, predetermined pressure is applied between the upper pressing die and the lower pressing die, and the temperature of the upper pressing die and the temperature of the lower pressing die are controlled at the same time, so that the bent and formed TAC lens is subjected to heat preservation and pressure maintaining for a predetermined time, and the anti-deformation TAC lens is obtained finally. The invention further provides a machining device for the anti-deformation TAC lens.

Description

technical field [0001] The invention relates to a processing method of an anti-deformation TAC lens. Background technique [0002] TAC lenses are the most common type of lenses in polarized sunglasses. [0003] In the prior art, the processing of TAC lenses is completed by baking and bending machines. The baking bending machine generally includes an upper die and a lower die matched with the upper die. The upper pressing die and the lower pressing die are provided with a heating device. In addition, the upper die has an arc-shaped protrusion structure, and the first lower die has an arc-shaped groove structure, and a through hole is formed in the middle thereof, and the through hole is connected to a vacuum pump. When in use, a pre-treated TAC lens is generally placed on the lower die, and vacuumed by the vacuum pump, so that the pre-treated TAC lens is adsorbed on the lower die; The pretreated TAC lens is heated, and the first lower pressing mold is pressed down to defo...
