Description

Technical Field

[0001] This invention relates in particular to an optical lens processing system. Background Technology

[0002] Optical lenses are commonly used in products such as watches, eyeglasses, and photographic equipment. During the manufacturing process of these products, oil or dirt may adhere to the lens components. Therefore, a wiping process is required before product assembly to ensure that the lenses have a high degree of cleanliness.

[0003] Traditionally, lens workpieces are wiped manually, which is inefficient and the yield rate of wiped lens workpieces is difficult to guarantee. To improve efficiency, automated wiping equipment exists in related fields to achieve automatic wiping of lens workpieces. For example, Chinese Patent Publication No. CN217797599U discloses a double-sided lens cleaning and wiping device, including a frame and cleaning devices located on the frame. The frame is equipped with a rotating platform, and the rotating platform has wiping stations evenly distributed along its circumference. There are two sets of cleaning devices, located above and below the rotating platform, respectively. Each cleaning device includes a fixed frame, and the fixed frame is equipped with a vertical sliding platform. The vertical sliding platform is equipped with a rotary wiping head driven by a wiping motor. The rotary wiping heads of the cleaning devices above and below the rotating platform wipe the lenses at the same wiping station by moving closer to or away from each other through their respective vertical sliding platforms. Each wiping station includes a lens mounting cylinder, and the upper inner wall of the lens mounting cylinder is equipped with a limiting shoulder.

[0004] However, the aforementioned wiping station can only accommodate lenses of a single diameter, and there is no fixed clamping connection between the lens mounting cylinder and the lens. When the lens is wiped by the cleaning device in the lens mounting cylinder, the lens will deflect and rub against the lens mounting cylinder, which can easily lead to lens wear. To solve the above problem, the aforementioned patent also discloses a circumferential positioning pin extending towards the top end face of the lens mounting cylinder on the limiting shoulder. The positioning pin is used to match the positioning groove at the outer edge of the lens to prevent the lens from rotating. In summary, the existing structure of positioning pin and positioning groove can prevent the lens from deflecting in the lens mounting cylinder. However, the above method requires a notch to be opened on one side of the lens, which increases the difficulty of lens processing. Moreover, when the lens is placed, its notch and positioning pin need to be positioned. This can easily lead to the lens being worn or scratched due to misalignment when the operator places the lens manually, causing the lens surface to rub against the positioning pin. This makes it inconvenient for the operator to use.

[0005] Therefore, there is a need to provide an optical lens processing system to improve upon the problems mentioned above. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide an optical lens processing system.

[0007] An optical lens processing system includes a frame, on which a rotating platform and a cam divider for intermittently rotating the rotating platform are respectively arranged. A plurality of clamps for clamping and fixing lenses are evenly distributed along the circumference of the rotating platform. A wiping device for wiping and cleaning the lenses in the clamps is provided on the frame. The clamps include an annular fixed seat and a movable seat. A driving member for moving the movable seat up and down relative to the annular fixed seat is provided on the frame on one side corresponding to the wiping device.

[0008] The upper side of the annular fixed seat is provided with several clamping arms that can swing relatively elastically around the circumference with the inner ring as the center. The inner side of the clamping arm has a protrusion, and the outer side of the clamping arm has a flange. The movable seat is movably sleeved on the annular fixed seat and movably abuts against the lower side of the flange. The movable seat has a notch on the outer side away from the center of the rotating platform. The driving component includes a push plate and a driving component that drives the push plate to move up and down. The notch of any movable seat is movably sleeved on the push plate as the rotating platform rotates.

[0009] In one embodiment, the driving component is a cylinder or an electric telescopic rod, with a connecting seat at its driving end. A screw is provided on the lower side of the push plate, and a screw hole is provided on the upper side of the connecting seat. The screw is threadedly inserted into the screw hole, and a first limiting nut and a second limiting nut are threadedly fitted onto the screw at intervals. The connecting seat is clamped between the first limiting nut and the second limiting nut.

[0010] In one embodiment, the height of the notch is greater than the thickness of the push plate.

[0011] In one embodiment, when the clamping arms are initially in the same state, they are all in an elastically distancing state relative to the inner ring of the annular fixing seat, expanding outwards.

[0012] In one embodiment, several clamping arms are elastically deformable and integrally formed and connected to an annular fixed base.

[0013] In one embodiment, a plurality of clamping arms are rotatably mounted on an annular fixed base, and torsion springs are respectively abutted at the rotatable connection between the clamping arms and the annular fixed base. The clamping arms are respectively swinging in a relatively far apart state through the torsion springs. A plurality of limiting blocks are arranged at intervals along the circumference on the annular fixed base, and the relative outer sides of the clamping arms abut against the limiting blocks respectively.

[0014] In one embodiment, the rotating platform is provided with a plurality of perforations evenly distributed along the circumference, and a plurality of clamps are provided in a one-to-one correspondence with the plurality of perforations, and the inner ring area of ​​the annular fixing seat is located within the area of ​​the perforations.

[0015] The wiping device has two sets, which are respectively set on the frame and symmetrically distributed on the upper and lower sides of the fixture.

[0016] In one embodiment, the wiping device includes a wiping mechanism and an acetone injection mechanism;

[0017] The wiping mechanism includes a lifting seat, a lifting component for driving the lifting seat to move up and down, a motor mounted on the lifting seat, and a connecting block mounted on the motor drive shaft. A sponge is detachably connected to the connecting block.

[0018] The acetone injection mechanism includes an injection pipe located on one side of the frame that can inject acetone into the sponge. One end of the injection pipe is connected to a sealed cylinder that can hold acetone via a pipe. A liquid pump is provided between the injection pipe and the sealed cylinder.

[0019] In one embodiment, an air curtain device is provided on the frame above the rotating platform; the air curtain device includes a fan, an air duct connected to the output end of the fan, and a fan plate connected to one end of the air duct. The fan plate has an air outlet with a ring shape on its lower side, and the air blowing from the air outlet blows towards the outer circumference of the rotating platform. A partition is provided on the frame below the rotating platform, and the air blowing from the air outlet forms a dustproof zone between the fan plate and the partition.

[0020] In one embodiment, the air outlet is oriented at an angle to the horizontal plane.

[0022] The present invention has several clamping arms arranged along the circumference on the upper side of the annular fixed base, and then the clamping arms are combined to form a lens placement area. The optical lens can be directly placed on the inner protrusion of the clamping arm. Then, the driving component drives the movable seat to move up and down along the annular fixed base. The movable seat is moved and abuts against the outer flange of the clamping arm, so that the clamping arms are in a relatively close swinging converged state, so as to realize the clamping and fixing of the lens by the clamping arms, thereby avoiding the situation where the lens is synchronously deflected and worn when the wiping device rotates and wipes the lens.

It is highly adaptable and has a simple structure. Moreover, the movement of any movable seat can be driven by a single driving component, which effectively reduces costs and meets production needs.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] like Figures 1 to 6 The present invention preferably provides an optical lens processing system, including a frame 1. The frame 1 is respectively provided with a rotating platform 2 and a cam divider 3 for intermittently rotating the rotating platform 2. The rotating platform 2 is provided with a plurality of clamps 4 evenly distributed along the circumference for clamping and fixing lenses. The frame 1 is provided with a wiping device 5 for wiping and cleaning the lenses in the clamps 4. The clamps 4 include an annular fixed seat 41 and a movable seat 42. The frame 1 is provided with a driving member located on one side of the wiping device 5, which can drive the movable seat 42 to move up and down relative to the annular fixed seat 41.

[0032] The upper side of the annular fixed seat 41 is provided with several clamping arms 43 that can swing relatively elastically around the circumference with the inner ring as the center. The inner side of the clamping arm 43 has a protrusion 44, and the outer side of the clamping arm 43 has a flange 45. The movable seat 42 is movably sleeved on the annular fixed seat 41 and movably abuts against the lower side of the flange 45. The movable seat 42 has a notch 46 on the outer side away from the center of the rotating platform 2. The driving component includes a push plate 47 and a driving member 48 that drives the push plate 47 to move up and down. The notch 46 of any movable seat 42 is movably sleeved on the push plate 47 as the rotating platform 2 rotates.

[0033] Specifically, the wiping device is a relatively mature existing technology, which is equivalent to the cleaning device in the Chinese patent disclosed in the background art, and its principle and structure will not be described in detail here. Several clamping arms are arranged along the circumference on the upper side of the annular fixed seat, and the lens placement area is formed by the combination of the clamping arms. The optical lens can be directly placed on the inner protrusion of the clamping arm. Then, the driving component drives the movable seat to move up and down along the annular fixed seat. The movable seat is moved and abuts against the outer flange of the clamping arm, so that the clamping arms are in a relatively close swinging converged state, so as to realize the clamping and fixing of the lens by the clamping arms, thereby avoiding the situation where the lens is synchronously deflected and worn when the wiping device rotates and wipes the lens.

[0034] Furthermore, the displacement length of the movable seat can be driven by the driving component to adjust the degree of convergence of several clamping arms swinging relatively close, thereby achieving clamping of lenses of different diameters. It is highly adaptable and has a simple structure. Moreover, the movement of any movable seat can be driven by a single driving component, which effectively reduces costs and meets production needs.

[0035] Furthermore, the outer side of the annular fixed seat can be designed to be non-circular, so that when the movable seat is fitted onto the outer side of the annular fixed seat, it can guide the up and down movement of the movable seat relative to the annular fixed seat, thus avoiding the problem that the notch and the push plate cannot be aligned due to the movable seat deflecting relative to the annular fixed seat. Alternatively, a guide pin can be set on the annular fixed seat, and the movable seat can be fitted onto the guide pin to guide its movement.

[0036] Furthermore, the driving component 48 is a cylinder or an electric telescopic rod, with a connecting seat 49 at its driving end. A screw 50 is provided on the lower side of the push plate 47, and a screw hole (not shown) is provided on the upper side of the connecting seat 49. The screw 50 is threadedly inserted into the screw hole (not shown), and a first limiting nut (not shown) and a second limiting nut (not shown) are threadedly fitted onto the screw 50 at intervals. The connecting seat 49 is clamped between the first limiting nut (not shown) and the second limiting nut (not shown). The height of the notch 46 is greater than the thickness of the push plate 47.

[0037] Specifically, the push plate is connected to the screw hole of the connecting seat via a screw, and the push plate can be adjusted and moved relative to the connecting seat by the screw to adjust the height position of the push plate in the notch. When the distance the push plate moves driven by the driving component is fixed, the distance between the push plate and the notch can be adjusted to adjust the moving distance of the movable seat relative to the annular fixed seat, thereby adjusting the relative convergence degree of several clamping arms to meet the clamping of lenses of different sizes.

[0038] The first and second limiting nuts are threadedly connected to the screw and clamped to both sides of the connecting seat to achieve relative fixation between the screw and the connecting seat, effectively preventing the push plate from shifting in height within the notch due to friction causing the screw to rotate relative to the connecting seat.

[0039] Furthermore, in the initial state, the clamping arms 43 are all in an elastically expanding state that is relatively far away from the inner ring of the annular fixed seat 41. In one embodiment, the clamping arms 43 are elastically deformable and integrally formed and connected to the annular fixed seat 41. In another embodiment, the clamping arms 43 are rotatably disposed on the annular fixed seat 41, and torsion springs are respectively abutted at the rotatable connection between the clamping arms 43 and the annular fixed seat 41. The clamping arms 43 are respectively in a swinging state that is relatively far away through the torsion springs. A number of limiting blocks 53 are arranged at intervals along the circumference on the annular fixed seat 41, and the relative outer sides of the clamping arms 43 abut against the limiting blocks 53 respectively.

[0040] Specifically, the clamping arms can be integrally formed with the annular fixed base through elastic deformation, or they can be elastically rotated on the annular fixed base through the cooperation of a rotating shaft and a torsion spring. There is no limitation here. That is, the clamping arms can be relatively elastically expanded outward in the initial state when there is no external force.

[0041] Furthermore, the rotating platform 2 is provided with a plurality of perforations 21 evenly distributed along the circumference, and a plurality of clamps 4 are provided in a one-to-one correspondence with a plurality of perforations 21, and the inner ring area of ​​the annular fixing seat 41 is located within the area of ​​the perforations 21; the wiping device 5 has two sets, which are respectively provided on the frame 1 and symmetrically distributed on the upper and lower sides of the clamps 4.

[0042] Specifically, two sets of wiping devices are set up so that they can wipe and clean the upper and lower sides of the lens inside the clamp respectively.

[0043] Furthermore, the wiping device 5 includes a wiping mechanism and an acetone injection mechanism; the wiping mechanism includes a lifting seat 61, a lifting component 62 for driving the lifting seat 61 to move up and down, a motor 63 mounted on the lifting seat 61, and a connecting block 64 mounted on the drive shaft of the motor 63, with a sponge 65 detachably connected to the connecting block 64; the acetone injection mechanism includes an injection pipe 66 mounted on one side of the frame 1 for injecting acetone into the sponge 65, one end of the injection pipe 66 being connected to a sealed cylinder 67 capable of holding acetone via a pipe, and a liquid pump (not shown in the figure) is provided between the injection pipe 66 and the sealed cylinder 67.

[0044] Specifically, the lifting component is a relatively mature existing technology. It can be a cylinder, an electric telescopic rod, or a combination of a motor and a screw. There are no restrictions here, as long as it can drive the lifting seat to move up and down. A liquid pump is used to inject acetone from the sealed cylinder into the sponge through the injection pipe. At this time, the sponge absorbs acetone. The lifting component then drives the lifting seat to move up and down so that the sponge moves and fits against the lens in the clamp. At this time, the motor drives the connecting block to rotate, thereby causing the sponge to rotate and wipe the lens to achieve cleaning of the lens.

[0045] Furthermore, an air curtain device is installed on the frame 1 above the rotating platform 2. The air curtain device includes a fan 71, an air duct 72 connected to the output end of the fan 71, and a fan disc 73 connected to one end of the air duct 72. The fan disc 73 has an annular air outlet 74 on its lower side, and the air outlet 74 blows air towards the outer circumference of the rotating platform 2. A partition 75 is installed on the frame 1 below the rotating platform 2. Air is blown through the air outlet 74 to form a dustproof zone between the fan disc 73 and the partition 75. The air outlet 74 is inclined at an angle to the horizontal plane. Specifically, the fan blows air through the air duct into the fan disc, and finally forms an annular air curtain covering the rotating platform through the annular air outlet of the fan disc, thereby effectively preventing dust from entering the lenses adhering to the fixture, thus achieving dust and dirt prevention for the lenses during and after cleaning.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
