Description

Technical Field

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

[0002] Optical lenses are transparent optical elements that use optical phenomena such as reflection, refraction, and absorption to adjust the direction of light propagation, focus, or diffuse it. They are widely used in various fields such as optical instruments and photographic equipment.

[0003] During the production of optical lenses, rounding is often required. As described in the Chinese patent application CN202420697550.2, a rounding mold for optical lens processing, it includes: "a base plate, a rectangular frame fixedly connected to one end of the base plate, a T-shaped block slidably connected to the rectangular frame, a rectangular hole near the top of the T-shaped block, and sliding grooves on both sides of the top of the T-shaped block, both of which communicate with the rectangular hole. A screw block is slidably connected to the rectangular hole, and vertical plates are fixedly connected to both ends of the screw block. The two vertical plates slide through adjacent sliding grooves, and oblique holes are opened at the top of both vertical plates. This invention achieves automatic clamping and fixing of the lens, as well as grinding. Because the lens is stably fixed, the quality of the rounding is guaranteed. It also facilitates effective clamping and fixing of lenses of different thicknesses, reducing manual labor intensity and demonstrating highly practical technical effects."

[0004] Through a search of the aforementioned patents, we found that the rounding of optical lenses is mainly achieved through the meshing and disengagement of a first bevel gear and a second bevel gear. Meshing enables the rounding action, while disengagement enables the replacement of the optical lens. In other words, the meshing of two bevel gears is required for normal rounding. However, as is well known, optical lenses come in various diameters. When rounding different sized optical lenses in the aforementioned applications, it is difficult to achieve the desired result. Specifically, when a larger diameter optical lens is clamped, it obstructs the grinding disc, preventing the two bevel gears from meshing and the grinding disc from rotating properly. Conversely, when a smaller diameter optical lens is clamped, the distance between the grinding disc and the lens is too great after the two bevel gears mesh, making it difficult for the grinding disc to contact the lens for rounding. Therefore, based on the fact that the above technology can only perform rounding on optical lenses of the same size, we have specifically designed a rounding mold with wider applicability for optical lens production. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chamfering mold for optical lens production, comprising a worktable, a turntable rotatably connected to the top of the worktable, an adjusting groove equidistantly formed on the top of the turntable, and an adjusting component driven by a servo motor 1 slidably connected in the adjusting groove; the adjusting component includes a movable plate and a support frame 1, an electric push rod 2 mounted on the top of the support frame 1, a servo motor 3 mounted on the inner wall of the movable plate, a clamping plate rotatably connected to the power output shaft of the electric push rod 2, and a clamping plate also fixed on the power output shaft of the servo motor 3; a support component is provided on one side of the top of the worktable, the support component including a fixed plate and a support frame 2, a servo motor 2 mounted on the top of the support frame 2, and a grinding disc provided on the power output shaft of the servo motor 2.

[0007] As a further embodiment of this utility model: there are multiple servo motors, each installed on one side of each adjusting slide groove. The inner cavity of the turntable and the position at the bottom of each servo motor are provided with a cavity. The power output shaft of the servo motor moves through the cavity and is connected to a drive gear. A driven gear meshes with the drive gear. A lead screw is connected to one side of the driven gear. The side of the lead screw away from the driven gear moves through the adjusting slide groove.

[0008] As a further embodiment of this utility model: the support frame is fixed to one side of the top of the movable plate, and an adjusting slider is also fixed to the bottom of the movable plate. The adjusting slider is placed in the adjusting groove and threaded with the lead screw. The adjusting slider slides in the adjusting groove by the rotation of the lead screw.

[0009] As a further embodiment of this utility model: silicone sheets are fixed to the bottom of the clamping plate on the electric push rod 2 and the top of the clamping plate on the servo motor 3, and the clamping plate on the electric push rod 2 corresponds to the clamping plate on the servo motor 3.

[0010] As a further embodiment of this utility model: the fixing plate is fixed on the workbench, an electric push rod is installed inside the workbench, a groove is provided at the bottom of the support frame, and the top of the power output shaft of the electric push rod is fixedly connected to the groove at the bottom of the support frame.

[0011] As a further embodiment of this utility model: a rotating shaft is fixed at the center of the bottom of the turntable, and a driven gear two is connected to the bottom of the rotating shaft. A cavity two is formed inside the worktable, and a drive motor is installed on the inner wall of the cavity two. A driving gear two is connected to the power output shaft of the drive motor, and the driving gear two meshes with the driven gear two.

[0012] As a further embodiment of this utility model: the bottom of the turntable is slidably attached to the top of the worktable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] I. In this application, through the design of a turntable, adjusting slide, adjusting components, and servo motor, the distance between the optical lens held on the clamping plate and the grinding plate can be effectively adjusted, so that optical lenses of different sizes can be clamped and brought close to the grinding plate. This allows the application to perform rounded corner processing on optical lenses of different sizes, effectively improving the applicability of the application. Compared with the prior art, which can only process optical lenses of the same size, it is more practical and can effectively reduce the procurement costs of enterprises.

[0015] Second, in this application, by designing a turntable and setting multiple sets of adjustment components on the turntable, optical lenses at different positions can be transferred sequentially to the grinding disc by rotating the turntable, and the grinding disc is used for rounding corner processing. During processing, the optical lenses on one set of adjustment components can be disassembled and installed on other sets of adjustment components, and this process is repeated in sequence. Compared with the prior art, which requires waiting for the current optical lens to be processed and disassembled before the next optical lens can be processed, this method is more convenient to operate and can improve the processing efficiency of optical lenses.

[0016] Third, in this application, the design of the fixed plate, electric push rod one, and support frame two allows the height of the grinding disc to be adjusted by activating the electric push rod one. When the thickness of the optical lens changes, the height of the grinding disc can be adjusted to adapt, so that optical lenses of different thicknesses can also be rounded normally, further improving the applicability of this application.

[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 A chamfering mold for optical lens production includes a worktable 1. A turntable 2 is rotatably connected to the top of the worktable 1. The bottom of the turntable 2 slides against the top of the worktable 1, which facilitates the stable rotation of the turntable 2. An adjusting groove 3 is provided at equal intervals in a ring shape on the top of the turntable 2. An adjusting component 4 driven by a servo motor 5 is slidably connected in the adjusting groove 3. The adjusting component 4 includes a movable plate 401 and a support frame 402. An electric push rod 10 is installed on the top of the support frame 402, and a servo motor is installed on the inner wall of the movable plate 401. The power output shaft of the electric push rod 10 is rotatably connected to a clamping plate 12, and the power output shaft of the servo motor 11 is also fixed with a clamping plate 12. A support assembly 6 is provided on one side of the top of the worktable 1. The support assembly 6 includes a fixing plate 601 and a support frame 602. A servo motor 7 is installed on the top of the support frame 602. A grinding disc 8 is provided on the power output shaft of the servo motor 7. The grinding disc 8 is connected to the power output shaft of the servo motor 7 by bolts, which can facilitate the replacement of the grinding disc 8 in the future.

[0025] Please see Figure 1 and Figure 2In this embodiment, there are multiple servo motors 5, each installed on one side of each adjusting slide groove 3. A cavity 13 is provided in the inner cavity of the turntable 2 at the bottom of each servo motor 5. The power output shaft of the servo motor 5 passes through the cavity 13 and is connected to the drive gear 501. A driven gear 502 meshes with the drive gear 501. A lead screw 503 is connected to one side of the driven gear 502. The side of the lead screw 503 away from the driven gear 502 passes through the adjusting slide groove 3. The support frame 402 is fixed to the top side of the movable plate 401. An adjusting slider 4011 is also fixed to the bottom of the movable plate 401. The adjusting slider 4011 is placed in the adjusting slide groove 3 and threaded with the lead screw 503. The adjusting slider 4011 slides in the adjusting slide groove 3 by the rotation of the lead screw 503.

[0026] Specifically, when the servo motor 5 starts, the forward and reverse rotation of the power output shaft of the servo motor 5 can drive the drive gear 501 to rotate forward and reverse, which in turn drives the driven gear 502 meshing with it to rotate forward and reverse, thereby driving the lead screw 503 to rotate forward and reverse. After the lead screw 503 rotates, it can drive the adjusting slider 4011 threaded with it to move in the adjusting groove 3. The movement of the adjusting slider 4011 drives the movable plate 401 and the support frame 402 to move closer to or away from the grinding disc 8, so that the entire adjusting assembly 4 and the optical lens clamped inside it can move closer to or away from the grinding disc 8.

[0027] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, silicone sheets 1201 are fixed to the bottom of the clamping plate 12 on the electric push rod 2 10 and the top of the clamping plate 12 on the servo motor 3 11. The clamping plate 12 on the electric push rod 2 10 corresponds to the clamping plate 12 on the servo motor 3 11.

[0028] Specifically, by setting a silicone sheet 1201 on the clamping plate 12, the two clamping plates 12 can improve the stability of the optical lens after clamping and avoid damage to the optical lens.

[0029] Please see Figure 1 and Figure 2 In this embodiment, the fixing plate 601 is fixed on the workbench 1. An electric push rod 9 is installed inside the workbench 1. A groove is provided at the bottom of the support frame 602. The top of the power output shaft of the electric push rod 9 is fixedly connected to the groove at the bottom of the support frame 602.

[0030] Specifically, after the electric push rod 9 is started, it can use its power output shaft to push the support frame 602 to rise or fall, thereby adjusting the height of the grinding disc 8 on the support frame 602 to accommodate optical lenses of different thicknesses.

[0031] Please see Figure 1 and Figure 3 In this embodiment, a rotating shaft is fixed at the center of the bottom of the turntable 2, and a driven gear 17 is connected to the bottom of the rotating shaft. The worktable 1 has a cavity 14 inside, and a drive motor 15 is installed on the inner wall of the cavity 14. A driving gear 16 is connected to the power output shaft of the drive motor 15, and the driving gear 16 meshes with the driven gear 17.

[0032] Specifically, after the drive motor 15 starts, it can drive the second drive gear 16 and the second driven gear 17 to rotate, thereby driving the rotating shaft at the bottom of the turntable 2 to rotate, ultimately achieving the effect of driving the turntable 2 to rotate.

[0033] In use, the optical lens that needs to be rounded is mounted on the clamping plate 12 connected to the servo motor 3 11. The electric push rod 2 10 is started. The power output shaft of the electric push rod 2 10 pushes the clamping plate 12 connected to it to descend, thereby cooperating with the clamping plate 12 connected to the servo motor 3 11 to clamp the optical lens for subsequent rounding processing.

[0034] By starting the servo motor 5, the power output shaft (forward and reverse rotation) of the servo motor 5 drives the drive gear 501 to rotate. The rotation of the drive gear 501 drives the driven gear 502, which in turn drives the lead screw 503 to rotate. The rotation of the lead screw 503 drives the adjusting slider 4011, which is threaded onto it, to move. This, in turn, moves the movable plate 401 and the support frame 402, allowing the entire adjusting assembly 4 to move away from or closer to the grinding disc 8. Ultimately, this allows the clamped optical lens to engage with the grinding disc 8. (If the optical lenses in the current batch are of uniform size, the position of the adjusting assembly 4 does not need to be changed. If it is necessary to process optical lenses of different sizes, simply restart the servo motor 5 for adjustment.)

[0035] When the servo motor 7 is started, it can drive the grinding disc 8 connected to it to rotate, thereby realizing the rounding grinding process on the clamped optical lens;

[0036] Once the optical lens on one set of adjustment components 4 is processed, the drive motor 15 is started. The power output shaft of the drive motor 15 drives the second drive gear 16 to rotate, which in turn drives the driven gear 17 meshing with it to rotate, thereby driving the turntable 2 to rotate. The rotation of the turntable 2 can move the next adjustment component 4 to a position close to the grinding disc 8. In other words, when the optical lens on one set of adjustment components 4 is being rounded, other adjustment components 4 that are far away from the grinding disc 8 can install and remove the optical lens without affecting the optical lens being ground. This can greatly improve the convenience of operation, improve the processing efficiency, and shorten the waiting idle period.

[0037] When the thickness of the optical lens changes, the electric push rod 9 can be activated. The power output shaft of the electric push rod 9 drives the support frame 602 to move, thereby changing the height of the grinding disc 8. After the height of the grinding disc 8 is adjusted, it is possible to perform rounding processing on optical lenses of different thicknesses.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
