    • The present invention relates to an apparatus and a method for manufacturing a polarizing lens film. The apparatus includes: a humidifying and heat treating unit which heat-treats a film combined with an annular fixing jig under a humidified atmosphere while transferring the film, to elongate the film exposed from a center portion of the fixing jig; a molding unit which inserts a molding jig into the fixing jig fixing the film treated in the humidifying and heat treating unit to mold the elongated film in a predetermined curvature; a heat treating unit which heat-treats the fixing jig fixing the film and the molding jig combined with the fixing jig while transferring the fixing jig and the molding jig, to cure the film; and a cutting unit which cuts the film to remove an unnecessary portion, thus obtaining a polarizing lens film having a curvature. According to the present invention, a flat film is heat-treated in a state fixed to an annular jig under a humidified atmosphere to stretch a non-fixed portion at an inner side of the jig by moisture and heat, and the stretched portion is pressurized by using a pressuring unit having a predetermined curvature and is heat-treated to mold so as to conform to a curvature of lens to be applied and then to be attached to the lens. Therefore, a polarizing light lens film has effects in that an overall uniform elongation percentage can be obtained compared to a method in which a flat film is directly bonded in close contact with a surface of the lens, thereby preventing occurrence of the defect of the product.
    • 本发明涉及一种制造偏光镜片的装置和方法。 该装置包括:加湿和热处理单元,其在转移膜的同时在加湿气氛下热处理与环形固定夹具结合的膜,从而使从固定夹具的中心部分露出的膜伸长; 模制单元,其将成型夹具插入固定夹具中,固定在加湿和热处理单元中处理的膜以预定曲率模制细长膜; 热处理单元,其在传送固定夹具和成型夹具的同时热固化固定薄膜的固定夹具和与定影夹具组合的成型夹具,以使膜固化; 以及切割单元,其切割膜以去除不需要的部分,从而获得具有曲率的偏振透镜膜。 根据本发明,在加湿气氛下,以固定于环状夹具的状态对平膜进行热处理,通过湿气和热量在夹具的内侧拉伸非固定部分,并且将拉伸部分加压 通过使用具有预定曲率的加压单元,并进行热处理以模制以符合要施加的透镜的曲率然后附着到透镜。 因此,偏振光透镜膜的效果在于,与将透镜的表面紧密接触的平膜直接接合的方法相比,可以获得整体均匀的伸长率,从而防止产品的缺陷的发生 。
