Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically a high-precision transfer molding device for optical lenses. Background Technology

[0002] Optical lens processing is a crucial step in the field of optical manufacturing, and its precision and quality directly affect the imaging performance of optical systems. Optical lens transfer molding equipment is the core equipment in optical glass lens molding technology. By placing softened optical glass into a high-precision mold, optical parts that meet the requirements of use are directly molded in one go under heated, pressurized, and oxygen-free conditions. This not only ensures that the optical glass lens can accurately replicate the microstructure and shape of the mold surface, but also reduces labor costs. After the lens is processed, the inability to quickly demold it leads to continuous contact between the lens and the mold surface, causing surface damage, which seriously affects the optical performance of the lens, resulting in light scattering and reduced image clarity.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202220702880.7, application date 2022-03-29) provides a molding device for corner protectors, comprising: a support, a male mold, and a female mold; a lifting assembly for connecting the male mold to the support; and a demolding assembly connected to the female mold. The female mold includes female mold a and female mold b, which are slidably fitted together. The demolding assembly includes a first support plate and a second support plate. The first support plate is connected to the female mold a. The support is further provided with a second electric push rod for moving the first support plate. The second support plate is connected to the female mold b and is slidably fitted to the first support plate. The support is also provided with a third electric push rod for driving the second support plate. The demolding assembly improves the processing efficiency of the corner protectors.

[0004] Some brittle optical plastics may crack or peel off at their edges or surfaces during molding due to pressure and mold friction, resulting in debris. In addition, uneven particle size of the material may also cause problems, as larger particles may detach from the whole material during molding, forming debris. During use, the above-mentioned device cannot reduce the residual debris on the worktable surface, causing light scattering from the lens, reducing image quality, lowering the overall quality of the optical lens, shortening the mold's lifespan, and increasing equipment maintenance costs and downtime. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision transfer molding device for optical lenses, in order to solve the problems mentioned in the background art, such as the inability to reduce the residual debris on the worktable surface, which leads to light scattering in the lens, reduces image quality, reduces the overall quality of the optical lens, shortens the service life of the mold, and increases equipment maintenance costs and downtime.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision transfer molding device for optical lenses, comprising a base, an upper mold slidably connected to the upper surface of the base, a worktable fixedly connected to the upper surface of the base, a control console fixedly connected to the lower right side of the base, and a motor fixedly connected to the upper rear side of the base; a rotating shaft fixedly connected to the output end of the motor, and the rotating shaft rotatably disposed inside the upper mold; a fixing plate fixedly connected to the front upper side of the base; a limiting rod fixedly connected inside the fixing plate, and a connecting rod slidably connected through the limiting rod, and a push plate fixedly connected to the end of the connecting rod near the worktable, and the push plate slidably disposed inside the upper mold.

[0007] The above structural design, through the setting of limiting rods and connecting rods, not only ensures the precise and stable movement trajectory of the push plate, but also avoids lens damage caused by push plate movement deviation, greatly improving the accuracy of demolding operation and helping to improve product yield, ensuring that the produced optical lenses meet high-precision quality requirements.

[0008] Preferably, a fixing block is fixedly connected to the front side of the upper end of the base, and the rotating shaft is rotatably arranged inside the fixing block, and the connecting rod is threadedly connected to the surface of the rotating shaft.

[0009] The above structural design, through the setting of fixed blocks and rotating shafts, enables the rotating shaft to maintain a stable axial position during rotation, avoiding wobbling or displacement, thereby improving the production quality of optical lenses.

[0010] Preferably, the connecting rods are symmetrically distributed about the center of the push plate, and a lower mold is fixedly connected to the upper surface of the worktable.

[0011] The above structural design, through the connecting rod and the lower mold, ensures the mold position is fixed during lens demolding, and the dimensional accuracy of the lens will not be affected by mold movement, thus producing optical lens products that meet high precision requirements.

[0012] Preferably, the push plate is slidably connected inside the lower mold, and the lower surface of the push plate is in contact with the upper surface of the worktable.

[0013] The above structural design, through the set push plate and worktable, allows the lens to be smoothly ejected from the lower mold, and ensures the stability of the push plate during the pushing process, avoiding damage to the lens caused by the tilting or shaking of the push plate, thereby achieving efficient and damage-free demolding.

[0014] Preferably, a baffle is fixedly connected to one end of the upper surface of the base near the fixed plate, and a drive shaft is rotatably arranged inside the baffle.

[0015] The above structural design, by incorporating baffles and a drive shaft, ensures stable transmission during rotation, preventing swaying or deviation due to lack of effective support, thus improving the stability of the device during operation.

[0016] Preferably, bevel gears are fixedly connected to both the surface of the drive shaft and the surface of the rotating shaft, a sliding rod is fixedly connected to the left side of the fixed plate, and a movable plate is threadedly connected to the surface of the drive shaft.

[0017] The above structural design, through the setting of the moving plate and sliding rod, can precisely control the moving distance and speed of the moving plate along the drive shaft axis, so as to meet the high precision requirements of component position during the production of optical lenses of different specifications and improve the processing accuracy of the product.

[0018] Preferably, the sliding rod is slidably connected to the moving plate, and a sweeping bar is fixedly connected to the lower surface of the moving plate. The sweeping bars are evenly distributed on the lower surface of the moving plate, and the lower surface of the sweeping bar is in contact with the upper surface of the worktable.

[0019] The above structural design, through the setting of sweeping bars and moving plates, can thoroughly clean the surface of the worktable, effectively removing debris and impurities from all parts of the worktable, leaving no cleaning dead corners, helping to keep the worktable surface clean, and providing a good foundation for subsequent lens processing.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the high-precision transfer molding equipment for optical lenses adopts a novel structural design, which not only enables the mold to be demolded quickly, but also reduces the wear of debris on the device and extends the service life of the device; the specific details are as follows:

[0021] (1) The high-precision transfer molding equipment for optical lenses reduces the residue of debris on the worktable surface by setting up a sweeping bar and a moving plate, ensuring the purity and optical quality of the lens, improving the product yield, reducing the wear of debris on the equipment, extending the service life of the mold, and reducing the maintenance cost and downtime of the equipment.

[0022] Furthermore, it reduces the time spent cleaning debris, enabling the equipment to operate more continuously, increasing the effective working time of the equipment, and improving the efficiency and quality of maintenance work.

[0023] (2) The high-precision transfer molding equipment for optical lenses achieves rapid demolding through the set push plate and connecting rod. This not only makes the mold surface uniformly stressed, reducing damage to the optical lens, but also better maintains the accurate size of the lens after molding, meeting the strict requirements of optical lenses for dimensional accuracy and improving the yield of products.

[0024] Furthermore, it reduces defective products caused by dimensional deviations, improves the stability and reliability of product quality, avoids mold damage, and reduces the frequency of mold repair and replacement.

[0025] (3) The high-precision transfer molding equipment for optical lenses, through the setting of limit rods and sliding rods, avoids shaking during the operation of the device, making the whole molding process more reliable, and at the same time enables the production of optical lenses with dimensional accuracy that meet strict standards, thereby improving the product yield.

[0033] 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.

[0034] Example 1: The base 1, fixing plate 10, and sliding rod 14 improve the stability of the device and prevent shaking during operation. Figures 1-2 As shown: It includes a base 1, an upper mold 2 fixedly connected to the upper surface of the base 1, a worktable 3 slidably connected to the upper surface of the base 1, a control console 18 fixedly connected to the lower right side of the base 1, a motor 4 fixedly connected to the upper rear side of the base 1, a rotating shaft 5 fixedly connected to the output end of the motor 4, and the rotating shaft 5 is rotatably disposed inside the upper mold 2. A fixing plate 10 is fixedly connected to the front upper side of the base 1, a limit rod 9 is fixedly connected inside the fixing plate 10, and a connecting rod 7 is slidably connected through the limit rod 9. A push plate 8 is fixedly connected to the end of the connecting rod 7 near the worktable 3, and the push plate 8 is slidably disposed inside the upper mold 2.

[0035] Workers use a conveying device to transport raw materials to the storage box at the top of the upper mold 2. After the raw materials are transported, workers adjust the stamping parameters through the control console 18 to ensure the best stamping effect. The device is then started, causing the upper mold 2 to slide on the top of the base 1. As the upper mold 2 and the lower mold 17 fit tightly together, the raw materials are discharged from inside the upper mold 2, thus processing the lens. The limiting rod 9 and sliding rod 14 prevent the device from shaking during operation, making the entire molding process more reliable. This also ensures the production of optical lenses with dimensional accuracy that meet strict standards, improving the product yield.

[0036] In Example 2, unlike Example 1, rapid demolding is achieved through the use of a fixed block 6, a rotating shaft 5, and a push plate 8, thus improving the working efficiency of the device. Figures 3-4 As shown: A fixing block 6 is fixedly connected to the front side of the upper end of the base 1, and a rotating shaft 5 is rotatably installed inside the fixing block 6. A connecting rod 7 is threadedly connected to the surface of the rotating shaft 5. The connecting rod 7 is symmetrically distributed about the center of the push plate 8. A lower mold 17 is fixedly connected to the upper surface of the worktable 3. A push plate 8 is slidably connected inside the lower mold 17, and the lower surface of the push plate 8 is in contact with the upper surface of the worktable 3. A baffle 13 is fixedly connected to the upper surface of the base 1 near the fixing plate 10, and a transmission shaft 12 is rotatably installed inside the baffle 13.

[0037] After the optical lens is molded, the operator uses the motor 4 to drive the output shaft 5 to rotate inside the fixed block 6. A connecting rod 7 is threaded onto the surface of the shaft 5. As the shaft 5 rotates, the connecting rod 7 slides on the surface of the limiting rod 9, causing the push plate 8 on the surface of the connecting rod 7 to demold the lens after molding. This allows the lens to quickly separate from the mold and move away from the upper surface of the worktable 3. This not only ensures that the mold surface is evenly stressed, reducing damage to the optical lens, but also better maintains the precise dimensions of the lens after molding, meeting the strict dimensional accuracy requirements of optical lenses, improving the product yield, reducing defects caused by dimensional deviations, enhancing the stability and reliability of product quality, and preventing mold damage, thus reducing the frequency of mold repair and replacement.

[0038] In Example 3, unlike Example 2, the use of bevel gear 11, sliding rod 14, and sweeping bar 16 reduces the amount of debris remaining on the surface of the worktable 3, thus improving the machining accuracy of the device. Figures 5-6 As shown: bevel gears 11 are fixedly connected to both the surface of the drive shaft 12 and the surface of the rotating shaft 5. A sliding rod 14 is fixedly connected to the left side of the fixed plate 10. A moving plate 15 is threadedly connected to the surface of the drive shaft 12. The sliding rod 14 is slidably connected through the moving plate 15. A sweeping bar 16 is fixedly connected to the lower surface of the moving plate 15. The sweeping bars 16 are evenly distributed on the lower surface of the moving plate 15. At the same time, the lower surface of the sweeping bar 16 is in contact with the upper surface of the worktable 3.

[0039] Bevel gears 11 are installed on both the surface of the drive shaft 12 and the surface of the rotating shaft 5. As the rotating shaft 5 rotates, it drives the drive shaft 12 to rotate inside the baffle 13. A movable plate 15 is threadedly connected to the surface of the drive shaft 12. As the drive shaft 12 rotates, the movable plate 15 slides on the surface of the sliding rod 14. At the same time, the sweeping bar 16 at the lower end of the movable plate 15 slides on the upper end of the worktable 3. This effectively reduces the residue of debris on the surface of the worktable 3, ensures the purity and optical quality of the lens, improves the yield of the product, reduces the wear of debris on the equipment, extends the service life of the mold, reduces the maintenance cost and downtime of the equipment, and shortens the time spent by the staff to clean up the debris. This allows the equipment to operate more continuously, improves the effective working time of the equipment, and improves the efficiency and quality of maintenance work.

[0040] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
