[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-5, which is the first embodiment of the utility model, provides an optical lens vacuum coating machine, which includes a machine body 1, a spray structure 2 and a placement rack 4 installed inside the machine body 1, and a vacuum pump 3 installed on one side of the machine body 1. The bottom of the placement rack 4 is provided with a placement plate 43 in an annular array, and the surface of the placement plate 43 is provided with a placement hole 44 in an annular array. The inside of the placement plate 43 is provided with a positioning member 5, and the inside of the machine body 1 is provided with a push member 6;

[0027] The positioning member 5 includes a gear 52 movably sleeved inside the placement plate 43, the interior of the gear 52 is fixedly connected with a rotating shaft 51, the top of the rotating shaft 51 extends to the top of the placement plate 43, a half gear 53 is provided on one side of the gear 52, the half gear 53 is meshed with the gear 52, and an arc groove 54 is opened inside the half gear 53. A motor is installed at the bottom of the spraying structure 2 to drive the rotation of the spraying structure 2, and the spraying structure 2 is provided with two groups of nozzles, which can spray coatings on the placement plates 43 in the annular array and the placement plate 43 in the middle of the placement rack 4.

[0028] The arc groove 54 is arranged in a circular array, and a positioning shaft 56 is movably sleeved inside the arc groove 54. A circular array of limiting grooves 55 are opened inside the half gear 53. Both ends of the positioning shaft 56 are fixedly connected with a retaining ring 57, and the retaining ring 57 is located on both sides of the half gear 53. The setting of the retaining ring 57 can limit the positioning shaft 56, so that the positioning shaft 56 will not be offset when it moves with the rotation of the arc groove 54, and the setting of the limiting groove 55 can limit the push rod 58.

[0029] A push rod 58 is fixedly connected to the surface of the positioning shaft 56, and an arc plate 59 is fixedly connected to one end of the push rod 58 and the end away from the retaining ring 57. The push rod 58 is located inside the limiting groove 55 and is movably connected thereto. The arc plate 59 is located inside the placement hole 44. The arc plate 59 can clamp lenses of different specifications and prevent the lenses from shaking when the placement tray 43 is removed. The structure of the positioning member 5 is located inside the placement tray 43, and the rotating shaft 51 extends to the top of the placement tray 43, which can facilitate the driving of the positioning member 5.

[0030] During use, the lens is installed inside the placement hole 44, and then the rotating shaft 51 is twisted to drive the gear 52 to rotate, and then drive the half gear 53 to rotate. During the rotation process, the half gear 53 will drive the arc groove 54 to rotate, so that the four groups of positioning shafts 56 move along the shape of the arc groove 54 as the arc groove 54 rotates. Due to the setting of the limiting groove 55, the positioning shaft 56 can push the push rod 58 and the arc plate 59 to move toward the direction of the lens, until the four groups of arc plates 59 completely clamp the lens to complete the positioning operation, thereby achieving the purpose of positioning lenses of different specifications, and further improving the stability of the lens.

[0031] Example 2

[0032] Reference Figure 1-6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0035] An internal thread 41 is fixedly installed at the bottom of the placement rack 4, and an external thread 42 is fixedly installed on the outer side of the placement plate 43. The internal thread 41 is threadedly connected with the external thread 42. The placement rack 4 and the placement plate 43 are connected through the internal thread 41 and the external thread 42, which makes it convenient to remove the placement plate 43 and is easy to operate.

[0036] When removing the coated lens, the motor 61 can be started to drive the transmission shaft 62 to rotate, and drive the slider 63 to move along the rotation of the transmission shaft 62, and drive the placement rack 4 to move toward the outside of the body 1 until the slider 63 moves to the end away from the motor 61. At this time, the placement rack 4 has extended to the outside of the body 1, so that the coated lens can be easily removed, and the frequency of shaking is further reduced. When the placement rack 4 moves to the outside of the body 1, the placement plate 43 is twisted to drive the external thread 42 to rotate along the inside of the internal thread 41 until the two are completely separated, and the placement plate 43 can be removed, which further achieves the purpose of simple operation and further solves the problem of cumbersome removal of the placement plate 43 in the prior art.
