Embodiment
Hereinafter with reference to relevant drawings, the optical element film coated appliance according to preferred embodiment of the present invention is described, wherein components identical will be illustrated with identical reference marks.
Please refer to Fig. 3～shown in Figure 4, comprise a pipe load-carrying unit 31, three separating elements 32, one first lid 33, and one second lid 34 according to the optical element film coated appliance 3 of preferred embodiment of the present invention.In the present embodiment, optical element film coated appliance 3 can be seized the substrate 4 of three colored drum optical filters simultaneously on both sides by the arms, to carry out film-plating process.
As Fig. 3, shown in Figure 5, pipe load-carrying unit 31 has three supporting parts 311 and three separating element connecting portions 313, wherein, supporting part 311 is positioned at the outer tube wall and the substrate 4 in order to carry colored drum optical filter respectively of pipe load-carrying unit 31, and separating element connecting portion 313 lays respectively at around the supporting part 311.In the present embodiment, the radian of each supporting part 311 is respectively 120 °, so that cooperate the shape of the substrate 4 of the colored drum optical filter of seizing on both sides by the arms of required carrying; Each separating element connecting portion 313 axis direction setting of parallel pipe load-carrying unit 31 respectively.In addition, pipe load-carrying unit 31 more comprises the portion 315 that is rotatably connected, the place, axle center that it is positioned at an end of pipe load-carrying unit 31 and is arranged at pipe load-carrying unit 31; At this moment, the portion 315 that is rotatably connected can be used for being connected (not shown) with a swivel bearing, so that utilize swivel bearing to come driven rotary pipe load-carrying unit 31.
