[0002] Optical coating refers to the process of coating a layer (or multiple layers) of metal (or dielectric) coating on the surface of optical parts. The purpose of coating the surface of optical parts is to reduce or increase the reflection, beam splitting, color separation, filtering, polarization and other requirements of light. Optical coating machines are often used to achieve coating operations.

[0003] During the coating process, the different distances between the evaporation source and the lens on the umbrella stand can easily lead to uneven coating on the lens. The existing solution is to add a correction plate between the umbrella stand and the evaporation source, and partially block the top of the evaporation source through the correction plate to make the film layer on the lens as uniform as possible. However, the correction plate is usually fixed, and the distances from each point of the correction plate to each lens on the umbrella stand are inconsistent, which still leads to uneven coating, low precision, and applicability needs to be improved.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 to Figure 2The present invention provides an adjustable correction device for an optical coating machine, comprising a frame 1 and three correction plates 4 connected to the frame 1, wherein the angles between adjacent correction plates 4 are equal, and the three correction plates 4 are located directly above the evaporation source. The correction plate 4 is connected to a support mechanism for supporting the correction plate 4, and the support mechanism is connected to a driving mechanism for driving the support mechanism and the correction plate 4 to rotate synchronously, and the driving mechanism comprises a motor 2, a steering gear 3, a conical gear 1 5, a conical gear 2 6, and a rotating shaft 8. The power output end of the motor 2 is connected to the input end of the steering gear 3, and the output end of the steering gear 3 is connected to the conical gear 1 5, and the conical gear 1 5 matches the conical gear 2 6. The end of the rotating shaft 8 is connected to the conical gear 2 6, and the support mechanism is connected to the rotating shaft 8.

[0018] The steering gear 3 is of prior art, and has a worm gear mechanism inside, that is, the output end of the motor 2 is connected to the worm gear, and then the power is output to the worm gear, and the worm gear is connected to the conical gear 5, thereby driving the conical gear 5 to rotate.

[0019] The rotation of the conical tooth 1 5 can drive the conical tooth 2 6 to rotate, thereby realizing the rotation of the rotating shaft 8. The rotating shaft 8 drives the supporting mechanism and the correction plate 4 to reciprocate around the axis of the rotating shaft 8, effectively blocking the gas from being directly sprayed on the umbrella frame, and adjusting the distance from the correction plate 4 to the umbrella frame lens to optimize the formation of a thin film with uniform thickness and improve the coating accuracy.

[0020] The supporting mechanism includes a clamping seat 9, a supporting plate 11, a transverse reinforcing plate 13, and a plurality of vertical reinforcing plates 12. The clamping seat 9 is connected to the rotating shaft 8, the supporting plate 11 is connected to the clamping seat 9, the end of the transverse reinforcing plate 13 is connected to the supporting plate 11, the end of the vertical reinforcing plate 12 is connected to the transverse reinforcing plate 13, and the transverse reinforcing plate 13 is connected to the bottom of the correction plate 4. The transverse reinforcing plate 13 and the vertical reinforcing plate 12 provide good support for the correction plate 4, and also make the correction plate 4 high in strength, prevent the correction plate 4 from being deformed due to heat, and improve the accuracy of subsequent coating.

[0021] The clamping seat 9 is provided with a positioning hole 10, and the rotating shaft 8 is provided with a threaded groove, which matches the positioning hole 10, and the threaded groove is threadedly connected with a bolt, and the nut of the bolt is pressed against the clamping seat 9, so that the clamping seat 9 is firmly connected to the rotating shaft 8, that is, the rotation of the rotating shaft 8 can synchronously drive the rotation of the clamping seat 9.

[0022] The transverse reinforcing plate 13 is provided with a plurality of connecting holes 14, and the connecting holes 14 are connected with screws, and the screws are threadedly connected with the correction plate 4.

[0023] The correction plate 4 is an elliptical structure, with the largest size in the middle and gradually decreasing sizes on both sides. Since the gas is in an umbrella-shaped structure when it is ejected from the evaporation source, the correction plate 4 with an elliptical structure can more effectively block the gas from being directly ejected onto the umbrella frame in practice, so that the uniformity of the film thickness is better.

[0024] The driving mechanism further includes two support seats 7 , the support seats 7 are connected to the bottom of the frame 1 , and the rotating shaft 8 is rotatably connected to the support seats 7 , thereby improving the rotation stability of the rotating shaft 8 .

The meshing connection has the advantages of high transmission efficiency, constant transmission ratio, simple structure, easy assembly and strong practicality.
