Description

Technical Field

[0001] This application relates to the field of lens coating, and in particular to a multi-point defocus control lens coating device. Background Technology

[0002] Multi-point defocus control lenses are specially designed eyeglass lenses designed to slow the progression of myopia by altering the focal point of incident light. The design principle is based on peripheral defocus theory, which states that when the eye focuses on near objects, the peripheral retina is in a hyperopic defocus state. This state can stimulate axial elongation, thus worsening myopia. Multi-point defocus control lenses, through special design, allow light to form multiple focal points in front of the retina after passing through the lens, simulating the state of distance vision, reducing peripheral hyperopic defocus, and achieving the goal of controlling myopia development. Multi-point defocus control lenses are often processed using coating equipment. Lens coating equipment is used to deposit one or more layers of material on the surface of a lens, mainly to change the optical properties of the lens. In conventional coating equipment, after connecting the machine to power, the lens is placed in a vacuum chamber at the top of the machine. After closing the cover at the top of the vacuum chamber, the air inside the vacuum chamber is evacuated using a vacuum pump, and then the machine applies the coating to the lens surface.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional coating equipment often requires manual flipping of lenses coated on one side to coat the other side. This requires repeated vacuum pumping, which takes a considerable amount of time and is inconvenient when coating multiple lenses.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The multi-point defocus control lens coating equipment provided in this application adopts the following technical solution:

[0007] A multi-point defocus control lens coating device includes a body, a vacuum cylinder movably connected to the top of the body, the bottom of the vacuum cylinder being sized to match the top of the body, and a shielding cover rotatably mounted on the top of the vacuum cylinder. A mounting frame is fixedly connected to the inner wall of the body, and a sliding frame is slidably mounted on the inner wall of the body. A connecting plate is rotatably connected to one end of both the mounting frame and the sliding frame. A limiting frame is fixedly mounted on the surface of the connecting plate. Two fixing ropes are fixedly connected to the inner wall of the limiting frame. The limiting frame has a C-shaped cross-section, and the fixing ropes are rubber ropes. The two fixing ropes are symmetrically distributed about the limiting frame as an axis.

An adjusting disk is slidably installed on the surface of the rotating frame, and one end of the adjusting disk is rotatably connected to the surface of the sliding frame. A synchronous belt is drivenly connected to the surfaces of the rotating disk and the adjusting disk, and the inner wall of the synchronous belt is drivenly installed to the surface of the connecting disk.

[0009] Preferably, the surfaces of the connecting plate, rotating plate, and adjusting plate are each provided with a plurality of limiting grooves, and the plurality of limiting grooves are arranged in a circular array with the center of the connecting plate as the axis.

[0010] Preferably, an electric push rod is fixedly installed at one end of the sliding frame, the bottom end of the electric push rod is fixedly connected to the inner wall of the machine body, and the electric push rod is perpendicular to the sliding frame.

[0011] Preferably, the rotating frame has a cross-shaped structure, and the surface of the rotating frame is rotatably connected to the inner wall of the sliding frame. The dimensions of the rotating frame surface are compatible with the dimensions of the inner wall of the adjusting plate.

The rotation of the limit brackets is controlled by rotating the connecting plate, thereby adjusting the angle of the lens and facilitating lens processing by the machine body. A motor is installed on the inner wall of the machine body, and a rotating plate and a rotating bracket are installed at the output end of the motor. An adjusting plate is slidably connected to the surface of the rotating bracket, and a synchronous belt is driven to the surface of both the rotating plate and the adjusting plate.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a multi-point defocus control lens coating device, referring to... Figure 1 - Figure 2 The system includes a main body 1. In use, after connecting the main body 1 to the power supply, the lens is placed in the vacuum cylinder 2 on the top of the main body 1. After closing the cover 3 on the top of the vacuum cylinder 2, the air inside the vacuum cylinder 2 is extracted by a vacuum pump. The main body 1 then coats the surface of the lens. The mounting bracket 4 and the sliding bracket 5 are connected to the inner wall of the main body 1. The surfaces of the mounting bracket 4 and the sliding bracket 5 are rotatably mounted with connecting plates 6. One end of the connecting plate 6 is equipped with a limit bracket 7. The inner wall of the limit bracket 7 is equipped with two rubber fixing ropes 8. The rubber material of the fixing ropes 8 has elastic properties, thereby improving the fixing effect of the lens. The lens is installed between the two limit brackets 7 by using the fixing ropes 8. The angle of the lens is adjusted by rotating the connecting plate 6 to control the rotation of the limit bracket 7. This facilitates the processing of the lens by the main body 1, effectively improving the convenience of lens coating and reducing the time required for lens coating.

[0024] Reference Figure 2 A motor 9 is installed on the inner wall of the machine body 1. A rotating disk 10 and a rotating frame 11 are installed at the output end of the motor 9. An adjusting disk 12 is slidably connected to the surface of the rotating frame 11. A synchronous belt 13 is driven to the surface of both the rotating disk 10 and the adjusting disk 12. The inner wall of the synchronous belt 13 is driven to the surface of the connecting disk 6. After the motor 9 is started, it controls the rotation of the rotating frame 11 and the rotating disk 10, thereby controlling the rotation of the connecting disk 6. This makes it more convenient to rotate the limiting frame 7. Several limiting grooves 14 are opened on the surface of the connecting disk 6, the rotating disk 10, and the adjusting disk 12. The limiting grooves 14 increase the friction between the connecting disk 6, the rotating disk 10, the adjusting disk 12 and the synchronous belt 13, preventing the synchronous belt 13 from slipping and affecting the rotation effect of the limiting frame 7.

[0025] Reference Figure 3 - Figure 4 An electric push rod 15 is installed on the inner wall of the body 1. One end of the electric push rod is connected to one end of the sliding frame 5. After adjusting its own length, the electric push rod 15 controls the sliding frame 5 to slide on the surface of the rotating frame 11, thereby adjusting the distance between the two limit frames 7, which facilitates the fixing of lenses of different sizes. The surface of the rotating frame 11 is slidably connected to the inner wall of the adjusting plate 12. The rotating frame 11 facilitates the movement of the sliding frame 5 and keeps the adjusting plate 12 rotating synchronously with the output end of the motor 9. A bearing 16 is installed at one end of the rotating frame 11. One end of the bearing 16 is rotatably connected to the inner wall of the body 1. The bearing 16 makes the rotating frame 11 more convenient to rotate. A connecting ring 17 is installed at one end of the sliding frame 5. The surface of the connecting ring 17 is rotatably connected to the inner wall of the adjusting plate 12. The connecting ring 17 connects the adjusting plate 12 and the sliding frame 5 and facilitates the rotation of the rotating plate 10.

[0026] The implementation principle of the multi-point defocus control lens coating equipment in this application embodiment is as follows: The mounting frame 4 and sliding frame 5 are connected to the inner wall of the machine body 1. A connecting plate 6 is rotatably mounted on the surface of both the mounting frame 4 and sliding frame 5. A limit frame 7 is installed at one end of the connecting plate 6. Two rubber fixing ropes 8 are installed on the inner wall of the limit frame 7. The rubber material of the fixing ropes 8 has elastic properties, thereby improving the fixing effect on the lens. This allows the lens to be installed between the two limit frames 7 using the fixing ropes 8. The rotation of the limit frame 7 is controlled by rotating the connecting plate 6, thereby adjusting the angle of the lens. This facilitates lens processing by the machine body 1 and reduces the time required for lens coating. A motor 9 is installed on the inner wall of the machine body 1. The output end of the machine 9 is equipped with a rotating disk 10 and a rotating frame 11. An adjusting disk 12 is slidably connected to the surface of the rotating frame 11. The surfaces of the rotating disk 10 and the adjusting disk 12 are both connected to a synchronous belt 13. The inner wall of the synchronous belt 13 is connected to the surface of the connecting disk 6 so that the rotating frame 11 and the rotating disk 10 can be controlled to rotate after the motor 9 is started, thereby controlling the rotation of the connecting disk 6. This makes it more convenient to rotate the limiting frame 7. Several limiting grooves 14 are opened on the surfaces of the connecting disk 6, the rotating disk 10, and the adjusting disk 12 to increase the friction between the connecting disk 6, the rotating disk 10, the adjusting disk 12 and the synchronous belt 13, so as to avoid the synchronous belt 13 slipping and affecting the rotation effect of the limiting frame 7.

[0027] An electric push rod 15 can also be installed on the inner wall of the body 1. One end of the electric push rod is connected to one end of the sliding frame 5, so that the sliding frame 5 can be controlled to slide on the surface of the rotating frame 11 after adjusting its own length by means of the electric push rod 15, thereby adjusting the distance between the two limit frames 7, which is convenient for fixing lenses of different sizes. The surface of the rotating frame 11 is slidably connected to the inner wall of the adjusting plate 12, so that the sliding frame 5 can be moved by means of the rotating frame 11, and the adjusting plate 12 can be kept in sync with the output end of the motor 9. A bearing 16 is installed on one end of the rotating frame 11, and one end of the bearing 16 is rotatably connected to the inner wall of the body 1, so that the rotating frame 11 can be rotated more conveniently by means of the bearing 16. A connecting ring 17 is installed on one end of the sliding frame 5, and the surface of the connecting ring 17 is rotatably connected to the inner wall of the adjusting plate 12, so that the adjusting plate 12 and the sliding frame 5 can be connected by means of the connecting ring 17, and the rotating plate 10 can be rotated.
