Description

Technical Field

[0001] The present invention relates to the field of lens manufacturing, and in particular to a lens manufacturing and curing device. Background Art

[0002] Lenses are transparent materials with one or more curved surfaces, made from optical materials such as glass or resin. After polishing, they are often assembled into eyeglass frames to correct the wearer's vision and provide a clear field of vision. Currently, lenses are typically made from resin or plastic, which are more durable than glass.

[0003] Under the existing technology, lenses are usually made by injecting raw materials into a mold and then fixing the raw materials through thermal curing. There are multiple steps in the process from raw material injection to thermal curing, all of which require manual participation. Although manual participation can improve the quality of the lens through observation, the processing efficiency is low, which affects product quality. Summary of the Invention

[0004] In order to solve the problem that in the existing technology, multiple steps from the injection of raw materials to the thermal curing process in the lens manufacturing process require manual participation. Although manual participation can improve the quality of the lens through observation, the processing efficiency is low, which affects the product quality. This application provides a lens production and curing equipment, and the specific solution is as follows.

[0007] A reflow groove is provided in the injection cover, and a reflow tank is provided on the injection cover corresponding to the reflow groove, and the reflow tank is connected to the reflow groove. A reflow hole is provided on the mold, and the reflow hole is aligned with the reflow groove. When the injection cover is fitted with the mold, the reflow groove is connected to the reflow hole. A sealing groove is also provided in the injection cover, and the sealing groove is connected to the reflow groove. A sealing block is provided in the sealing groove, and the sealing block is slidably connected to the sealing groove. A pushing member for pushing the sealing block is also provided in the sealing groove, and the sealing block can extend into the reflow groove and into the reflow hole, and the sealing block can completely seal the reflow groove and the reflow hole.

[0008] By adopting the above technical solution, the lens production and curing process can be completed efficiently. The setting of the conveying mechanism enables the mold to be stably transferred between each workstation, thereby improving production efficiency. The injection cover in the injection mechanism is embedded in the mold to ensure the accuracy of the injection process, avoid overflow of raw materials, and can be completed automatically. When bubbles are observed, the blocking block can be retracted to connect the reflux groove with the reflux hole. Due to the instantaneous change in air pressure, the bubbles can be discharged. The discharge of bubbles may also be accompanied by the reflux of part of the raw materials. The refluxed raw materials can be collected in the reflux tank, effectively improving the quality and efficiency of lens production.

[0009] Optionally, an ultrasonic flaw detector is provided on the injection head, and the ultrasonic flaw detector is used to detect bubbles in the mold. When the ultrasonic flaw detector detects bubbles, the blocking block is retracted into the blocking groove.

[0010] By adopting the above technical solution, the ultrasonic flaw detector can detect bubbles in the mold, promptly detect the mold that generates bubbles during injection, and automatically control the movement of the blocking block, thereby effectively avoiding the impact of bubbles on the quality of the lens and improving the product qualification rate.

[0011] Optionally, a sealing ring is fixedly provided on the injection hood, and the sealing ring is arranged around the position of the reflux groove. A sealing groove is provided on the mold corresponding to the sealing ring, and the sealing ring can be embedded in the sealing groove.

[0012] By adopting the above technical solution, the setting of the sealing ring can effectively enhance the sealing between the injection cover and the mold, preventing the raw material from leaking from the gap between the injection cover and the mold when bubbles appear and flow back during the injection process, thereby ensuring the stability of the injection process.

[0013] Optionally, a heating pipe is further provided at a position corresponding to the reflux groove in the injection hood, and the heating pipe is used to heat the reflux groove.

[0014] By adopting the above technical solution, the setting of the heating tube can heat the raw materials in the reflux tank, preventing the raw materials from solidifying or deteriorating in fluidity due to temperature drop during the reflux process, and can also reduce the situation where the reflux tank is blocked, thereby ensuring that the raw materials can smoothly reflux into the reflux tank.

[0015] Optionally, a pressing groove is further provided on the injection hood, and a pressing airbag is provided in the pressing groove, and the pressing airbag is used to abut against the mold.

[0016] By adopting this technical solution, the compression airbag can stably compress the mold during the injection process, effectively preventing the mold from shifting or loosening during injection, thereby improving injection accuracy and stability. It can also further seal the gap between the mold and the injection hood, reducing material leakage.

[0017] Optionally, a rubber strip is provided on the mold corresponding to the compression airbag, and the rubber strip can abut against the compression airbag.

[0018] By implementing this technical solution, the contact between the compression bladder and the mold is optimized. Specifically, the rubber strip effectively protects the mold surface from damage caused by the direct pressure of the compression bladder, while also enhancing sealing performance and preventing material leakage during injection. Furthermore, the combination of the rubber strip and the compression bladder enhances mold fixation stability, ensuring a smooth injection process.

[0019] Optionally, the pasting mechanism includes a pasting rack, a tape wheel is rotatably provided on the pasting rack, the tape wheel is used to install the tape, a separation rack is also provided next to the tape wheel, the separation rack is also rotatably connected to the pasting rack, and a bonding rod and a cutting rod are provided on the separation rack, and the bonding rod and the cutting rod are both provided in plurality and arranged adjacent to each other, and both the bonding rod and the cutting rod can abut the tape on the tape wheel, the bonding rod is used to bond the tape, and the cutting rod is used to cut the tape.

[0020] By adopting the above technical solution, the tape wheel can be used by the bonding rod to stick the tape out and pull it to fit the mold so that it can be closed when the mold completes injection molding, and the cutting rod can cut the completed tape. Then the separation frame continues to rotate so that the bonding rod can continue to bond with the tape and carry out tape pasting of the next mold.

[0021] Optionally, a spring is provided between the bonding rod and the separation frame, one end of the spring is fixedly connected to the bonding rod, and the other end of the spring is fixedly connected to the separation frame, and the spring has a tendency to push the bonding rod toward the tape wheel, and a spring is provided between the cutting rod and the separation frame, one end of the spring is fixedly connected to the cutting rod, and the other end of the spring is fixedly connected to the separation frame, and the spring has a tendency to push the cutting rod toward the tape wheel.

[0022] By adopting the above technical solution, the bonding rod has a tendency to move toward the tape wheel under the action of the spring, thereby ensuring that the tape can be firmly bonded, while the cutting rod can cut the tape more effectively, and after cutting, it can also scrape and press the tape, so that the tape fits more closely on the mold.

[0023] Optionally, an adhesive wheel is rotatably provided on one end of the adhesive rod away from the separation frame, and the adhesive wheel can abut against the tape on the tape wheel.

[0024] By adopting the above technical solution, the rotation setting of the bonding wheel can reduce the friction between the adhesive tape and the adhesive tape, making the separation process of the adhesive tape from the bonding wheel smoother after being pasted on the mold, and reducing the situation where the tape cannot be separated due to excessive friction.

[0025] Optionally, it also includes a stirring mechanism, which is used to store raw materials. A material passing pipe is provided between the stirring mechanism and the injection mechanism, and the material passing pipe is used to pass the raw materials in the stirring mechanism into the mold. It also includes a conveying mechanism, which is arranged along the stirring mechanism, the injection mechanism, the pasting mechanism, and the heat curing mechanism. The conveying mechanism includes a conveying seat, which can move along the conveying mechanism, and the conveying seat is detachably connected to the mold.

[0026] By adopting the above technical solution, the stirring mechanism can directly stir the required raw materials and inject them into the injection mechanism, which can stably provide the raw materials required for production, further improving the processing convenience. The conveying mechanism is used for transportation throughout the entire processing process, which can further improve the degree of automation and further improve production efficiency.

[0027] In summary, this application has at least the following beneficial effects:

[0028] The present application solves the problem that in the prior art lens manufacturing process, multiple steps from the injection of raw materials to the thermal curing process require manual participation. Although manual participation can improve the quality of lenses through observation, the processing efficiency is low, which affects product quality. The present application sets up automated equipment and uses machinery instead of manpower for processing, thereby improving processing efficiency and product quality.

[0029] The present application is also provided with a component capable of detecting and eliminating bubbles, thereby reducing the occurrence of bubbles during the product production process that affect the quality of the lens, and further improving product quality.

A conveying mechanism 4 is also provided at the injection mechanism 2, the pasting mechanism 3, and the heat curing mechanism 6. The conveying mechanism 4 includes a conveying seat 41. The conveying seat 41 can move along the conveying mechanism 4. A mold 5 is detachably provided on the conveying seat 41. The stirring mechanism 1 is used to store raw materials, and the injection mechanism 2 is used to inject raw materials into the mold 5. A material passing pipe is provided between the stirring mechanism 1 and the injection mechanism 2. The material passing pipe is used to pass the raw materials in the stirring mechanism 1 into the mold 5. The pasting mechanism 3 is used to stick the tape on the mold 5. The heat curing mechanism 6 is provided with multiple heating tubes 226 for heat curing raw materials. During specific implementation, the stirring mechanism 1 includes a stirring kettle, which can continue to stir the prepared raw materials so that the raw materials can be introduced into the injection mechanism 2 after meeting the usage requirements, and the heat curing mechanism 6 includes a heating chamber, and a heating pipe 226 is provided inside the heating chamber. An exhaust fan for heat dissipation is provided on the top of the heating chamber, and the conveying mechanism 4 also includes a conveyor belt, which is laid in the order from the injection mechanism 2 to the pasting mechanism 3 to the heat curing mechanism 6, and the conveying seat 41 can move along the conveyor belt as a whole.

[0043] like Figure 2 and Figure 3As shown, the injection mechanism 2 includes an injection frame 21, which is provided with a injection cover 22. The injection cover 22 is configured to correspond to the shape of the mold 5 and the mold 5 can be embedded in the injection cover 22. The injection frame 21 is provided with a driving member 23 for driving the injection cover 22. The injection cover 22 is provided with a injection head 24, which is connected to a feed pipe. The mold 5 is provided with a corresponding injection hole 51 corresponding to the injection head 24, and the injection head 24 can be embedded in the injection hole 51. In a specific embodiment, the driving member 23 includes a linear mechanism, and in other embodiments, a cylinder can also be used for driving.

[0044] like Figure 2 and Figure 3 As shown, the injection head 24 is provided with an ultrasonic flaw detector 241, which is used to detect bubbles in the mold 5. A reflux groove 221 is provided in the injection cover 22, and a reflux tank 25 is provided on the injection cover 22 corresponding to the reflux groove 221. The reflux tank 25 is connected to the reflux groove 221. A reflux hole 52 is provided on the mold 5, and the reflux hole 52 is aligned with the reflux groove 221. When the injection cover 22 is fitted to the mold 5, the reflux groove 221 is connected to the reflux hole 52. A blocking groove 222 is also provided in the injection cover 22, and the blocking groove 222 is connected to the reflux groove 221. A blocking block 224 is provided within the blocking groove 222. The blocking block 224 is slidably connected within the blocking groove 222. A pusher 223 is also provided within the blocking groove 222 for pushing the blocking block 224. The blocking block 224 can extend into the reflux groove 221 and into the reflux hole 52, completely sealing the reflux groove 221 and the reflux hole 52. When the ultrasonic flaw detector 241 detects bubbles, the blocking block 224 retracts into the blocking groove 222. A heating pipe 226 is also provided within the injection hood 22 at a position corresponding to the reflux groove 221. The heating pipe 226 is used to heat the reflux groove 221. In specific implementation, the pushing member 223 can be an electric push rod or a cylinder. When there are no bubbles, the blocking block 224 is normally extended into the reflux hole 52, so that the raw material can be normally passed into the mold 5. When there are bubbles, the ultrasonic flaw detector 241 can detect the bubbles and control the blocking block 224 to move. Due to the instantaneous change in air pressure, the internal gas will be discharged instantly, thereby achieving a defoaming effect. During the gas discharge process, part of the raw material may be discharged. At this time, the raw material is discharged through the reflux groove 221, and the heating tube 226 can keep the raw material in the reflux groove 221 from solidifying and clogging.

The mold 5 is provided with a sealing groove 53 corresponding to the sealing ring 225, and the sealing ring 225 can be embedded in the sealing groove 53. The injection shield 22 is also provided with a compression groove 227, and a compression airbag 228 is disposed in the compression groove 227. The compression airbag 228 is used to abut the mold 5. The mold 5 is provided with a rubber strip 54 corresponding to the compression airbag 228, and the rubber strip 54 can abut the compression airbag 228. In a specific embodiment, the sealing ring 225 can be embedded in the sealing groove 53, which not only serves to locate the material but also reduces the risk of material leakage from the reflux hole 52. The compression airbag 228 also serves a similar purpose, both locating the material and sealing the material inside to reduce the risk of material leakage. The rubber strip 54 can further enhance the sealing performance after contact, further improving the sealing effect and further enhancing the positioning effect.

[0046] like Figure 4 As shown, the pasting mechanism 3 includes a pasting frame 31, on which a tape wheel 32 is rotatably provided. The tape wheel 32 is used to install the tape.

A bonding rod 331 and a cutting rod 332 are provided on the separation frame 33. There are multiple bonding rods 331 and cutting rods 332 and they are arranged adjacent to each other. Both the bonding rod 331 and the cutting rod 332 can abut the tape on the tape wheel 32. The bonding rod 331 is used to bond the tape, and the cutting rod 332 is used to cut the tape. During specific implementation, a sticky substance is provided on the adhesive rod 331, and the non-sticky side of the tape is adhered by the sticky substance and the tape is pulled onto the mold 5 for pasting. After adjusting the size and position arrangement during pasting, the reflux hole 52 and the injection hole 51 can be pasted. After pasting is completed, the cutting rod 332 is just aligned with the tape, and the tape can be cut. After the tape is cut, part of the tape is suspended in the air. At this time, the tape can be pressed onto the mold 5 again by pasting and squeezing through the adhesive rod 331. Then, the above actions are repeated to complete the tape pasting of different molds 5.

[0047] like Figure 4As shown, a spring 333 is provided between the bonding rod 331 and the separation frame 33. One end of the spring 333 is fixedly connected to the bonding rod 331, and the other end of the spring 333 is fixedly connected to the separation frame 33. The spring 333 has a tendency to push the bonding rod 331 toward the tape wheel 32. A spring 333 is provided between the cutting rod 332 and the separation frame 33. One end of the spring 333 is fixedly connected to the cutting rod 332, and the other end of the spring 333 is fixedly connected to the separation frame 33. The spring 333 has a tendency to push the cutting rod 332 toward the tape wheel 32. An bonding wheel 334 is rotatably provided on the end of the bonding rod 331 away from the separation frame 33. The bonding wheel 334 can abut the tape on the tape wheel 32. In specific implementation, the spring 333 is set to enable the cutting rod 332 and the bonding rod 331 to further abut the tape on the tape wheel 32. When the tape is consumed, the cutting rod 332 and the bonding rod 331 can continue to press the tape tightly. After the pasting is completed, the cutting rod 332 can abut and push the pasted tape, making the tape more tightly pasted.

[0048] Working principle: By setting up highly automated equipment, machinery is used instead of manpower for processing, thereby improving processing efficiency and product quality. At the same time, defoaming is carried out during the production process to further improve product quality.

[0049] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
