DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the drawings in the specification.

[0026] Refer to Figures 1-5, which is the first embodiment of the present utility model, provides a lens hardening and coating device. This lens hardening and coating device includes a vacuum chamber 1, a coating device 2 and a container 3 installed inside the vacuum chamber 1. The container 3 is located on top of the coating device 2. Inside the vacuum chamber 1, a rotating member 4 and a stabilizing member 5 are installed. The rotating member 4 is located on top of the stabilizing member 5;

[0027] The rotating member 4 includes a driving motor 41 fixed to the top of the vacuum chamber 1. Inside the vacuum chamber 1, a rotating shaft 42 is rotatably connected. The output end of the driving motor 41 extends inside the vacuum chamber 1 and is fixedly connected to the rotating shaft 42. Inside the rotating shaft 42, a telescopic rod 43 is fixedly connected. One end of the telescopic rod 43 is movably sleeved with the rotating shaft 42. The telescopic rod 43 is square-shaped. A sealing ring is provided at the top of the rotating shaft 42, which can form a sealing structure between the output end of the driving motor 41, the rotating shaft 42 and the vacuum chamber 1 to prevent air from entering the inside of the vacuum chamber 1.

[0028] A connecting cylinder 44 is fixedly connected to the top of the container 3. Inside the connecting cylinder 44, a limiting plate 45 is fixedly connected. The top of the limiting plate 45 is fixedly connected to a connecting rod 46. The connecting rod 46 is fixedly connected to the connecting cylinder 44. The top of the connecting cylinder 44 extends to the top of the connecting cylinder 44, which is convenient for connecting with the telescopic rod 43. And a square groove is opened inside the connecting rod 46, which is convenient for connecting with the telescopic rod 43.

[0029] A connecting block 47 is fixedly connected to the surface of the connecting rod 46. One end of the telescopic rod 43 extends to the bottom of the rotating shaft 42 and extends into the inside of the connecting rod 46 and is movably connected to it. The square-shaped telescopic rod 43 and the square groove opened inside the connecting rod 46 can make the two closely connected, and the telescopic rod 43 can drive the connecting rod 46 to rotate, so that the container 3 rotates.

[0030] A bolt 48 is movably sleeved inside the connecting rod 46. The bolt 48 penetrates through the telescopic rod 43 and extends to the outside of the connecting rod 46 and is threadedly connected to the connecting block 47, which can facilitate the connection between the telescopic rod 43 and the connecting rod 46 and prevent the two from separating during rotation, thus ensuring the stability during rotation.

[0031] A cavity 492 is opened at the bottom of the container 3. Inside the cavity 492, pulleys 49 are installed. The pulleys 49 are arranged in a circular array. A collecting ring 491 is installed on the surface of the container 3. A positioning shaft is fixedly connected inside the pulley 49, and the positioning shaft is located inside the cavity 492 and is movably sleeved with it. A collecting groove for collecting excess hardening liquid is opened on the surface of the collecting ring 491.

[0032] The fixing member 5 includes a bearing ring 51 located at the top of the coating device 2. A circular slide rail 52 is provided on the surface of the bearing ring 51. The pulley 49 is located on the surface of the circular slide rail 52 and is movably connected thereto, which can make the vessel 3 more stable during rotation and prevent it from shifting during rotation, causing damage to the lens.

[0033] An annular array of sliders 53 is fixedly connected to the outside of the bearing ring 51. A slide bar 54 is movably sleeved inside the slider 53. The top of the slide bar 54 is fixedly connected with an anti - detachment ring 55. The diameter of the anti - detachment ring 55 is larger than that of the slide bar 54. The bottom of the slide bar 54 is fixedly connected to the vacuum chamber 1, which can make the lifting of the bearing ring 51 more stable.

[0034] A screw rod 56 is also threadedly connected inside the slider 53. The bottom of the screw rod 56 is rotatably connected to the vacuum chamber 1, which can drive the slider 53 to complete the lifting operation of the bearing ring 51, so that the vessel 3 is more stable during rotation and the installation and disassembly of the vessel 3 are convenient.

[0035] During use, place the vessel 3 on the surface of the bearing ring 51, so that the pulley 49 at the bottom of the vessel 3 is located on the surface of the circular slide rail 52 on the surface of the bearing ring 51. Then rotate the screw rod 56 to drive the bearing ring 51 to slowly rise through the slider 53 until the connecting cylinder 44 at the top of the vessel 3 and the connecting rod 46 rise to the surface of the telescopic rod 43, and the connecting rod 46 completely wraps the telescopic rod 43. At the same time, the telescopic rod 43 can be pulled to make one end of it move into the inside of the connecting rod 46 until it is completely located inside the square groove. Then insert the bolt 48 into the inside of the connecting rod 46, make it penetrate the telescopic rod 43 and extend to the other end of the connecting rod 46 until one end of the bolt 48 contacts the connecting block 47. Then rotate the bolt 48 to threadedly connect it with the connecting block 47, and the installation of the vessel 3 and the vacuum chamber 1 can be completed. Then close the door of the vacuum chamber 1 and perform the hardness coating operation through the coating device 2;

[0036] After the coating is completed, the driving motor 41 can be started to drive the output end to drive the rotating shaft 42 and the telescopic rod 43 to rotate. Since the telescopic rod 43 is square - shaped and is connected to the connecting cylinder 46 through the bolt 48, when the telescopic rod 43 rotates, it will drive the connecting rod 46, the connecting cylinder 44 and the vessel 3 to rotate, so that the vessel 3 rotates along the circular slide rail 52 on the surface of the bearing ring 51 through the pulley 49 at its bottom to ensure the stability of the rotation of the vessel 3. As the vessel 3 rotates, the excess hardening liquid will be slowly thrown out, and at the same time, the hardening liquid will slowly flow along the surface of the vessel 3 to the surface of the collecting ring 491. After the operation is completed, the vessel 3 can be removed by operating in the opposite way.
