Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically to a lens adsorption device. Background Technology

[0002] A lens is an optical device made of transparent material. Through its curved surface design, it can change the direction of light propagation, so that an object can form a clear image on the retina. It is widely used in devices such as eyeglasses, cameras, and telescopes, mainly for correcting vision (such as myopia, hyperopia, and astigmatism) or protecting the eyes from harmful light (such as ultraviolet light and blue light).

[0003] According to a lens adsorption and fixing device disclosed in patent number CN201921796188.X, the device includes an adsorption mechanism, an auxiliary clamping mechanism, a cleaning mechanism, a baffle, a platform, a storage box, and a support rod. The support rod is welded to the storage box above it. The platform and the baffle are located above the storage box. The storage box and the platform are fixedly connected by screws. The storage box and the baffle are glued together. The platform has a baffle around its circumference. The auxiliary clamping mechanism, the cleaning mechanism, and the adsorption mechanism are located above the platform. The device uses the cooperation of a clamping rod and an adjusting rod. By changing the position of the adjusting rod in the adjusting groove, the state of the clamping rod is changed. When the clamping rod is adjusted to a vertical state, it facilitates the pre-clamping of the lens and ensures the coaxiality of the lens optical center and the processing center. When the clamping rod is adjusted to a horizontal state, it facilitates the processing of the lens and prevents damage to the clamping rod during lens processing.

[0004] Existing lens adsorption devices mostly use a single suction cup structure, which has problems such as uneven distribution of adsorption force and inability to adapt to lenses with different curvatures or sizes. In addition, traditional devices lack dynamic air pressure adjustment function, which can easily lead to adsorption failure due to environmental changes or slight deformation of the lens. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a lens adsorption device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens adsorption device, comprising a base, a bearing disposed in the middle of the base, a rotating shaft disposed inside the bearing, a turntable fixedly connected to the top of the rotating shaft, a fixed seat fixedly connected to the upper surface of the turntable, a fixed housing fixedly connected to the upper surface of the fixed seat, a suction cup fixedly connected to the top of the fixed housing, a miniature air pressure sensor disposed inside the fixed housing, a miniature air pump disposed on the upper surface of the turntable, an air guide tube disposed on the outer surface of the miniature air pump, and a solenoid valve and a pressure relief valve disposed on the outer surface of the air guide tube.

[0007] Preferably, the bottom of the suction cup has a through hole, and the interior of the suction cup is connected to the interior of the fixed housing through the through hole.

[0008] Preferably, the outer surface of the air guide tube penetrates the fixed housing and extends into the inner cavity, and the miniature air pressure sensor is electrically connected to the miniature air pump.

[0009] Preferably, a limiting rod is sleeved inside the turntable, a fixing plate is fixedly connected to the outer surface of the limiting rod, and a spring is sleeved on the outer surface of the limiting rod.

[0010] Preferably, one end of the spring is fixedly connected to the upper surface of the fixed plate, and the other end of the spring away from the fixed plate is fixedly connected to the lower surface of the turntable.

[0011] Preferably, a pull block is fixedly connected to the top of the limiting rod, the pull block is positioned above the turntable, and the fixing plate is positioned below the turntable.

[0012] Preferably, the upper surface of the base is provided with a socket, and the interior of the socket is adapted to the outer surface of the limiting plug.

[0013] Beneficial effects

[0014] This invention provides a lens adsorption device. It has the following beneficial effects:

[0015] (1) The lens adsorption device achieves efficient adsorption and dynamic force adjustment of lenses of different sizes through the cooperation of the fixed housing, suction cup, through hole, micro air pressure sensor and micro air pump. With multiple sets of switchable suction cups, the device can be adapted to lenses of different sizes. The micro air pressure sensor monitors the air pressure change in the adsorption chamber in real time. When adsorbing lenses of different sizes or curvatures, the sensor and air pump work together to automatically replenish or exhaust air to maintain a constant adsorption force. This solves the problem that traditional single suction cup cannot adapt to multiple sizes of lenses and the air leakage caused by lens deformation. This design significantly improves the versatility and adaptability of the device, and is especially suitable for precision scenarios such as eyeglass processing and optical coating that require frequent switching of lens sizes.

[0016] (2) The lens adsorption device achieves rapid positioning and stable locking of the turntable through the cooperation between the limiting rod, spring, pull block and insertion hole. When the position of the suction cup needs to be adjusted, the operator only needs to pull the pull block upwards. The limiting rod disengages from the insertion hole of the base. After the spring is compressed, it releases elastic potential energy, allowing the turntable to rotate freely to the target angle. After the pull block is released, the spring pushes the limiting rod to insert into the corresponding insertion hole, forming a rigid limit, ensuring that the turntable does not deviate during the adsorption process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] like Figure 1-4 As shown, this utility model provides a lens adsorption device, including a base 1, a bearing 2 disposed in the middle of the base 1, a rotating shaft 3 disposed inside the bearing 2, a turntable 4 fixedly connected to the top of the rotating shaft 3, a fixed seat 5 fixedly connected to the upper surface of the turntable 4, a fixed housing 6 fixedly connected to the upper surface of the fixed seat 5, a suction cup 7 fixedly connected to the top of the fixed housing 6, a miniature air pressure sensor 9 disposed inside the fixed housing 6, a miniature air pump 10 disposed on the upper surface of the turntable 4, an air guide tube 11 disposed on the outer surface of the miniature air pump 10, and a solenoid valve 12 and a pressure relief valve 13 disposed on the outer surface of the air guide tube 11.

[0025] Specifically, the bottom of the suction cup 7 has a through hole 8, and the interior of the suction cup 7 is connected to the interior of the fixed housing 6 through the through hole 8.

[0026] Specifically, the outer surface of the air duct 11 penetrates the fixed housing 6 and extends into the inner cavity, and the miniature air pressure sensor 9 is electrically connected to the miniature air pump 10.

[0027] Specifically, a limiting rod 14 is fitted inside the turntable 4, a fixing plate 15 is fixedly connected to the outer surface of the limiting rod 14, and a spring 16 is fitted on the outer surface of the limiting rod 14.

[0028] Specifically, the end of the spring 16 is fixedly connected to the upper surface of the fixed plate 15, and the end of the spring 16 away from the fixed plate 15 is fixedly connected to the lower surface of the turntable 4.

[0029] Specifically, a pull block 17 is fixedly connected to the top of the limiting rod 14. The pull block 17 is positioned above the turntable 4, and the fixing plate 15 is positioned below the turntable 4.

[0030] Specifically, the upper surface of the base 1 is provided with a socket 18, and the interior of the socket 18 is adapted to the outer surface of the limiting plug 14.

[0031] The working principle and beneficial effects of the above embodiments.

[0032] In use, the turntable 4 is equipped with multiple sets of fixed housings 6, each set of fixed housings 6 having suction cups 7 of different sizes to facilitate the adsorption and fixation of lenses of different sizes. Lifting the pull block 17 upwards causes the limiting rod 14 to move away from the insertion hole 18 on the base 1, compressing the spring 16. Then, the turntable 4 is rotated, and according to the size of the lens, the suction cup 7 of the appropriate size rotates to the target position. Releasing the pull block 17, under the elastic pull of the spring 16, causes the limiting rod 14 to insert into the insertion hole 18 of the base 1, limiting the displacement of the turntable 4 and keeping it in its current position. This aligns the suction cup 7 on the fixed housing 6 with the lens surface. The through hole 8 at the bottom of the suction cup 7 connects to the inside of the fixed housing 6. When the micro air pump 10 draws air through the air guide tube 11, it creates a negative pressure in the suction cup 7, thereby adsorbing the lens. During this process, the micro air pressure sensor 9 monitors the air pressure value in the adsorption chamber in real time. If the air pressure fluctuates due to uneven lens surface or changes in ambient temperature, the micro air pressure sensor 9 transmits the signal to the micro air pump 10, which dynamically adjusts the adsorption force by replenishing or venting air to ensure stable adsorption. If the lens needs to be released, the pressure relief valve 13 opens to quickly release the negative pressure in the adsorption chamber, and the suction cup 7 separates smoothly from the lens. If other sizes of lenses need to be fixed, the operator can pull the limit plug 14 upward through the pull block 17 to release the locking state of the plug hole 18 and quickly adjust the angle of the turntable 4.
