Description

Technical Field

[0001] This utility model relates to the field of optical lens manufacturing technology, specifically to a lens bonding device for optical lens manufacturing and processing. Background Technology

[0002] Cemented lenses, also known as achromatic lenses, are a type of optical lens. Achromatic lenses consist of two lenses made of different materials bonded together to correct the dispersion of the glass. In the manufacturing of optical lenses, in order to meet the requirements of improving transmittance, eliminating chromatic aberration, and reducing the manufacturing difficulty of complex optical glasses, it is necessary to bond two lenses with opposite R values ​​and the same outer diameter material together. This requires the use of a lens bonding device.

[0003] A relevant reference is Chinese utility model patent CN219024882U, which discloses a lens bonding device for optical lens manufacturing.

It also achieves continuous heating and stirring of the glue inside the storage tank, preventing glue coagulation and affecting the extraction effect, thus greatly improving processing efficiency.

[0004] The aforementioned lens bonding device applies adhesive to the bonding surface of the lens by spraying adhesive. During the lens bonding and pressure holding process, the adhesive may overflow from the bonding surface, causing it to adhere to the outer edge of the lens. At the same time, the lens and the adhesive spraying position need to be transferred to the pressing position, and the transfer process affects production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lens bonding device for optical lens manufacturing and processing, which solves the problems of efficiency issues during lens transfer and glue overflow during pressure holding.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a lens bonding device for optical lens production and processing includes a base plate, and a bonding mechanism is provided above the base plate;

[0007] The downward pressure assembly, located above the base plate, is used to provide downward pressure to the lens;

[0008] A conveying assembly, positioned above the pressing assembly, is used to convey the colloid.

[0009] The support assembly includes a rodless cylinder fixedly mounted above a base plate, a support block fixedly mounted above the slider of the rodless cylinder, a housing fixedly mounted above the support block, a scraper fixedly mounted on one side of the housing, an electromagnetic stator fixedly mounted inside the housing, a support tube inserted through the center of the housing, a permanent magnet rotor fixedly mounted on the outside of the support tube, and a vacuum suction cup fixedly mounted inside the support tube.

[0010] Preferably, the pressing assembly includes a support frame fixedly installed above the base plate, a fixing plate fixedly installed above the support frame, a pressing piston fixedly installed above the fixing plate, a connecting plate fixedly installed at the bottom end of the pressing piston, a pressure bearing fixedly installed below the connecting plate, and a pressure plate fixedly installed below the pressure bearing.

[0011] Preferably, the fixed plate has cylindrical openings on its front and rear sides that match the diameter of the movable end of the pressing piston, and a rectangular strip opening is provided in the center of the fixed plate. The pressing piston is symmetrically installed on the top of the fixed plate, and its movable end passes through the fixed plate. The pressure plate is made of rubber, and the pressure plate is rotatably connected to the connecting plate through a pressure bearing.

[0012] Preferably, the conveying assembly includes a limiting frame fixedly installed above the fixed plate, a glue bucket fixedly installed at the center of the limiting frame, a gear metering pump fixedly installed at the bottom of the glue bucket, a drive motor fixedly installed below the gear metering pump, and a conveying pipe fixedly installed below the gear metering pump.

[0013] Preferably, the bottom of the glue bucket is provided with an opening structure that communicates with the top inlet of the gear metering pump. The drive motor is fixedly connected to the support frame, and the shaft of the drive motor passes through the opening structure in the center of the fixed plate and is fixedly connected to the drive shaft of the gear metering pump.

[0014] Preferably, the outer shell is mounted symmetrically on the support block from front to back. The electromagnetic stator is composed of an insulating frame and a coil inside the frame. The top end of the support tube is provided with a recessed structure that fits into the vacuum chuck. The top end of the support tube is provided with an annular protrusion structure, and a pressure bearing is also installed at the bottom of the protrusion structure at the top end of the support tube. Beneficial effects

[0015] This invention provides a lens bonding device for optical lens manufacturing. Compared with the prior art, it has the following advantages:

[0016] This lens bonding device for optical lens manufacturing utilizes a rodless cylinder. A support block is fixedly mounted above the slider of the rodless cylinder. The rodless cylinder moves the support block back and forth to adjust the position of the two outer shells. A vacuum suction cup in the center of a support tube movable inside the outer shell restricts the position of the lens. Furthermore, the upper pressing piston is symmetrically positioned above the fixed plate. This design allows the vacuum suction cup on the other side to be directly below the conveying tube while the lens on one side is below the pressing piston. This enables the lens on the other side to be glued during the pressing and holding stage of one lens, thereby improving production efficiency.

[0017] (2) The lens bonding device for optical lens production and processing, through the setting of the support tube, since the support tube is connected to the outer shell through the pressure bearing, the direction and magnitude of the current in the electromagnetic stator are controlled by the electronic commutator. When the electronic controller passes the alternating current to the stator winding, the electromagnetic stator will generate a rotating magnetic field. This rotating magnetic field interacts with the magnetic field of the permanent magnet rotor fixedly installed on the outside of the support tube. According to the principle of like poles repulsion and unlike poles attraction, the support tube will be subjected to electromagnetic force and rotate with the rotating magnetic field. The position of the lens is restricted by the vacuum suction cup inside the support tube. During rotation, the adhesive can be evenly distributed on the upper surface of the lens by centrifugal force. At the same time, the pressure plate is connected to the connecting plate at the bottom of the lower piston through the lower piston. During the pressure holding stage, the support tube drives the two lenses to rotate. The outer side of the lens will contact the scraper during the rotation. The scraper will scrape off the adhesive overflowing during the pressure holding process to prevent the adhesive from drying on the outer side of the lens after overflowing and affecting the lens quality.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a lens bonding device for optical lens production and processing, including a base plate 1, and a bonding mechanism 2 is provided above the base plate 1;

[0025] The pressing assembly 21 is disposed above the base plate 1 to provide downward pressure to the lens. The pressing assembly 21 includes a support frame 211 fixedly installed above the base plate 1, a fixing plate 212 fixedly installed above the support frame 211, a pressing piston 213 fixedly installed above the fixing plate 212, a connecting plate 214 fixedly installed at the bottom end of the pressing piston 213, a pressure bearing 215 fixedly installed below the connecting plate 214, and a pressure plate 216 fixedly installed below the pressure bearing 215. The front and rear sides of the fixing plate 212 are provided with cylindrical opening structures that match the diameter of the movable end of the pressing piston 213, and the center of the fixing plate 212 is provided with a rectangular strip opening structure. The pressing piston 213 is symmetrically installed above the fixing plate 212, and its movable end passes through the fixing plate 212. The pressure plate 216 is made of rubber, and the pressure plate 216 is rotatably connected to the connecting plate 214 through the pressure bearing 215.

[0026] Specifically, the base plate 1 can support the bonding mechanism 2, and the support frame 211 restricts the position of the fixing plate 212. The fixing plate 212 can support the pressing pistons 213 at both ends and restrict the position of the pressing pistons 213. The pressing pistons 213 drive the connecting plate 214 to move downward, so that the bottom end of the pressure plate 216 contacts the upper lens, thereby applying pressure between the two lenses.

[0027] The conveying assembly 22 is disposed above the pressing assembly 21 for conveying the colloid. The conveying assembly 22 includes a limiting frame 221 fixedly installed above the fixing plate 212. A glue tank 222 is fixedly installed at the center of the limiting frame 221. A gear metering pump 223 is fixedly installed at the bottom of the glue tank 222. A drive motor 224 is fixedly installed below the gear metering pump 223. A conveying pipe 225 is fixedly installed below the gear metering pump 223. The bottom of the glue tank 222 is provided with an opening structure communicating with the top inlet of the gear metering pump 223. The drive motor 224 is fixedly connected to the support frame 211, and the shaft of the drive motor 224 passes through the opening structure at the center of the fixing plate 212 and is fixedly connected to the drive shaft of the gear metering pump 223.

[0028] Specifically, the limiting frame 221 can limit the position of the glue bucket 222, which is used to store glue. When the drive motor 224 drives the gear metering pump 223 to operate, the glue inside the glue bucket 222 will enter the gear metering pump 223 through the opening structure at the bottom of the glue bucket 222, and then enter the delivery pipe 225 after passing through the gear metering pump 223. The delivery pipe 225 reduces the distance between the glue and the lens when the glue is discharged, preventing the glue from splashing after falling.

[0029] The support assembly 23 includes a rodless cylinder 231 fixedly installed above the base plate 1. A support block 232 is fixedly installed above the slider of the rodless cylinder 231. A housing 233 is fixedly installed above the support block 232. A scraper 234 is fixedly installed on one side of the housing 233. An electromagnetic stator 235 is fixedly installed inside the housing 233. A support tube 236 is inserted through the center of the housing 233. A permanent magnet rotor 237 is fixedly installed on the outside of the support tube 236. A vacuum chuck 238 is fixedly installed inside the support tube 236. The housing 233 is mirror-symmetrically installed above the support block 232. The electromagnetic stator 235 consists of an insulating frame and a coil inside the frame. The top of the support tube 236 has a recessed structure that fits into the vacuum chuck 238. The top of the support tube 236 has an annular protrusion. A pressure bearing 215 is also installed at the bottom of the protrusion at the top of the support tube 236.

[0030] Specifically, the rodless cylinder 231 can drive the support block 232 to move back and forth. The housing 233 is set above both sides of the support block 232 to provide two lens placement positions. Since the support tube 236 is rotatably connected to the housing 233 through the pressure bearing 215, the direction and magnitude of the current flow in the electromagnetic stator 235 are controlled by the electronic commutator. When the electronic controller passes alternating current to the stator winding, the electromagnetic stator 235 will generate a rotating magnetic field. This rotating magnetic field interacts with the magnetic field of the permanent magnet rotor 237 fixedly installed on the outside of the support tube 236. According to the principle of like poles repulsion and unlike poles attraction, the support tube 236 will be subjected to electromagnetic force and rotate with the rotating magnetic field. The position of the lens is restricted by the vacuum chuck 238 inside the support tube 236. During rotation, the colloid can be evenly distributed on the upper surface of the lens by centrifugal force.

[0031] Specifically, the model of the downward piston 213 is TTC-11LA15AB1000-CGAT, the model of the gear metering pump 223 is CX-WGMP, the model of the drive motor 224 is HSS0604A, the model of the rodless cylinder 231 is CY1SG15-200Z, and the model of the vacuum suction cup 238 is XP30Z-N1. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] During operation, the support block 232 is fixedly installed above the slider of the rodless cylinder 231. The rodless cylinder 231 drives the support block 232 to move back and forth, thereby adjusting the position of the two outer shells 233. The position of the lens is restricted by the vacuum suction cup 238 at the center of the support tube 236, which is movably installed inside the outer shell 233. The upper pressing piston 213 is symmetrically arranged above the fixed plate 212. This method allows the vacuum suction cup 238 on the other side to be directly below the conveying tube 225 when the lens on one side of the support block 232 is below the pressing piston 213. This allows for the application of adhesive to the lens on the other side during the pressing and holding stage of one side of the lens, thereby improving production efficiency. Since the support tube 236 is rotatably connected to the outer shell 233 through the pressure bearing 215, an electronic commutator is used to control the direction and magnitude of the current flow in the electromagnetic stator 235. When the electronic controller... When an alternating current is applied to the stator winding, the electromagnetic stator 235 generates a rotating magnetic field. This rotating magnetic field interacts with the magnetic field of the permanent magnet rotor 237 fixedly installed on the outside of the support tube 236. According to the principle of like poles repelling and unlike poles attracting, the support tube 236 will be subjected to electromagnetic force and rotate with the rotating magnetic field. The position of the lens is restricted by the vacuum chuck 238 inside the support tube 236. During rotation, the colloid can be evenly distributed on the upper surface of the lens by centrifugal force. At the same time, the pressure plate 216 is rotatably connected to the connecting plate 214 at the bottom of the pressure piston 213 through the pressure piston 213. During the pressure holding stage, the support tube 236 drives the two lenses to rotate. During the rotation, the outer side of the lens will come into contact with the scraper 234. The scraper 234 scrapes off the colloid that overflows during the pressure holding process to prevent the colloid from drying on the outer side of the lens and affecting the lens quality.
