The first processing module 2, the second processing module 3, and the third processing module 4 are arranged on the machine body 1. The first processing module 2, the second processing module 3, and the third processing module 4 are interconnected. The first processing module 2 and the third processing module 4 are further provided with an inflation and deflation device 7. The inflation and deflation device 7 is used to fill nitrogen into the first processing module 2 and the third processing module 4 and discharge air. The mold shifting platform 5 is provided at the bottom of the first processing module 2. The first processing module 2 is used to perform preliminary processing on the lens. The second processing module 3 is used to pressurize the lens after heating. The third processing module 4 is used to discharge the lens after cooling.

[0040] Among them, the lens is placed on the mold shifting platform 5 and transferred to the bottom of the first processing module 2 by the mold shifting module 6.

The lens is then pushed to the second processing module 3, heated to the set temperature and then pressurized and cut. After completion, it begins to cool down to below the annealing point. The mold shifting module 6 then pushes the mold to the third processing module 4 for cooling.

[0041] The utility model enables the equipment to simultaneously perform molding and cooling internally through the first processing module, the second processing module, and the third processing module. Among them, the second processing module performs molding internally, and the third processing module performs cooling at the same time. After cooling, it is responsible for loading and unloading preforms and finished lenses, which greatly improves the efficiency and flexibility of the production process.

[0042] In the present invention, primary processing refers to transporting the lens to a first processing module and then providing a processing environment.

[0043] Optionally, the mold shifting platform 5 includes a positioning portion 51, a first driving device 54, and a second driving device 55. The first driving device 54 is located at the bottom of the positioning portion 51 and is used to lift the positioning portion 51.

[0048] After the first processing module 2 completes processing, the push pin 62 pushes the lens on the positioning portion 51 to the second processing module 3 .

[0049] In this embodiment, the mold shift module design provides a highly effective automated mold transfer function, in which the third drive device drives the push pin into the second opening, thereby achieving precise positioning and smooth transfer of the lens. This automated mechanism significantly improves the continuity and efficiency of the production process, while reducing the possibility of human operational errors, ensuring consistency in processing accuracy and product quality.

[0050] Preferably, a magnetic-driven transmission system can be used to replace the traditional push rod and drive device.

This system can also enhance operational flexibility and adapt to more diverse working environments and different process requirements.

[0051] Optionally, the second processing module 3 includes a pressurizing device 31 and a heating device 32. The pressurizing device 31 passes through the top of the second processing module 3 and is used for pressure molding the lens.

[0052] In this embodiment, the design of the second processing module combines a pressurizing device and a heating device, both of which are arranged on the top of the module. This integrated design enables the lens to be heated and pressure-formed at the same location, thereby effectively improving processing efficiency and product quality. The pressurizing device ensures precise shape forming, while the heating device provides the necessary heat treatment. The two work together to achieve the best molding effect and material properties.

[0053] Preferably, an adjustable multi-zone heating system can be used to replace the existing single heating device: such a system allows more precise control of the heating temperature and area, adapting to lenses of different thicknesses and materials, thereby further improving the adaptability and accuracy of processing.

[0055] In this embodiment, the gas filling and discharging devices 7 on the top of the first processing module and the third processing module have the function of automatically filling with nitrogen and exhausting air. This design greatly improves the stability and safety of the processing environment. The use of nitrogen can effectively reduce the potential negative impact of oxygen on the lens processing process, thereby improving product quality. In addition, the automated gas management system ensures the consistency of the working environment, reduces the need for manual operation, and enhances the continuity and efficiency of production.

[0056] Preferably, an intelligent environmental monitoring device can be added to replace the traditional gas filling and deflation device. This system can monitor and adjust the gas composition and pressure in the processing environment in real time to adapt to different production requirements.

[0057] Optionally, the third processing module 4 is further provided with a fourth driving device 41, a discharge portion 42 and a third opening 43, wherein the third opening 43 is located at the front side of the third processing module 4, and the discharge portion 42 is located on the fourth driving device 41;

[0058] Among them, when the second processing module 3 completes processing, the push pin 62 pushes the lens located in the second processing module 3 to the discharge part 42 in the third processing module 4. After the third processing module 4 cools the lens through the inflation and deflation device 7, the fourth driving device 41 drives the discharge part 42 through the third opening 43.

[0059] In this embodiment, the third processing module 4 is equipped with a fourth driving device 41 and a discharge portion 42, which effectively improves the discharge efficiency and safety of the lens. Through the precise control of the third opening 43, the lens can be quickly and safely moved out of the processing area after the cooling treatment of the inflation and deflation device 7. This design not only optimizes the product processing flow and ensures the quality and stability of the lens during the production process, but also speeds up the operation speed of the entire production line.

[0060] Preferably, automated robotic arm technology can be used to replace the traditional drive device and discharge part: the robotic arm can provide a more flexible operating range and higher precision to adapt to complex production needs. In addition, the introduction of the robotic arm can further reduce manual intervention, improve production efficiency, and reduce labor costs and potential operational errors.

[0061] Optionally, the positioning portion 51 is further provided with a first limiting portion 52 and a second limiting portion 53 , and the first limiting portion 52 and the second limiting portion 53 are used to locate the position of the lens.

[0062] In this embodiment, the first limiting portion 52 and the second limiting portion 53 on the positioning portion 51 provide high-precision support for lens positioning, ensuring that each lens is in an ideal position during the processing. This precise positioning system significantly improves the consistency and repeatability of the processing, helps to reduce product defects and improve the quality of the final product. In addition, this positioning mechanism also optimizes the processing process and improves the overall efficiency of the production line.

[0063] Preferably, an automatic positioning system based on vision recognition can be used to replace traditional mechanical limit components: this system uses high-precision cameras and image processing technology to identify and position lenses, providing more flexible and automated operations, reducing physical wear, and being able to adapt to a wider range of product specifications and size changes.

[0064] Optionally, a universal wheel 11 is further provided at the bottom of the body 1 .

[0065] In this embodiment, the universal wheels 11 provided at the bottom of the body 1 give the entire device excellent mobility and flexibility: this allows the device to be easily moved to different production lines or work areas within the factory, greatly facilitating the adjustment of the production layout and the maintenance of the equipment. At the same time, the design of the universal wheels also helps to quickly deploy or reconfigure the production line to meet changing production needs, while reducing the labor intensity during the equipment transfer process.

[0066] Preferably, a combination of fixed brackets and adjustable casters can be used instead of the existing universal wheels. This system provides the necessary mobility while also increasing the stability of the equipment in a specific location. Adjustable casters allow the equipment to be easily locked in place when it needs to be fixed, preventing errors caused by movement during high-precision work, while providing flexibility when the equipment needs to be moved.

[0067] Optionally, a fixing member 12 is further provided at the bottom of the body 1, and the fixing member 12 can move vertically to make the body 1 rise or fall.

[0068] In this embodiment, the vertically movable fixing part 12 at the bottom of the body 1 allows the body to be raised or lowered as needed, providing great operational flexibility and adaptability: this design enables the equipment to adapt to different production environments and the height of operators, improving the operating comfort and efficiency of the staff. At the same time, the adjustable height feature also facilitates the docking of the equipment with other production line interfaces, ensuring a smooth and efficient production process.

[0069] Preferably, a hydraulic or electric lifting system can be used to replace traditional mechanical fixings: the use of a hydraulic or electric lifting system can provide a smoother, faster and more precise height adjustment function, enhancing user experience and operational convenience. In addition, the introduction of an electric or hydraulic system can also reduce the need for physical operation, thereby reducing labor intensity and improving work safety.

[0070] Optionally, a display device 8 is further provided on the machine body 1, and the display device 8 is used to display the current step of the processing flow.

[0071] In this embodiment, the display device 8 configured on the body 1 provides the function of real-time display of the current step of the processing flow, which greatly improves the transparency and convenience of operation. Through this visual interface, the operator can monitor the entire processing process in real time, quickly identify and solve any potential production problems, thereby improving production efficiency and product quality. In addition, the display device 8 also helps to reduce operational errors and ensure that each step of processing can be executed accurately.

[0072] Preferably, the traditional display device 8 is upgraded to an interactive touch screen: this advanced display system can not only display information, but also allow the operator to make adjustments and input instructions directly on the screen, providing a more intuitive and flexible operating experience. The introduction of the touch screen can further improve operating efficiency, enhance the friendliness of the user interface, and reduce operational complexity through direct interaction.

[0073] Preferably, an electronic control system can be added. The electronic control system can be installed on the machine body 1 and integrated with the existing display device 8 to form a centralized control and display platform.

[0074] In addition, the electronic control system should have a highly automated control function, which can automatically control the operation of key components such as heating devices, pressurizing devices, and inflation and deflation devices, as well as the precise movement and positioning of the mold. This not only improves the accuracy of the operation, but also greatly reduces the need for manual operation.

[0075] Preferably, in this embodiment, the first drive device, the second drive device, the third drive device, and the fourth drive device can adopt a variety of different types of drive technologies.

[0076] Stepper motor: This drive device is very common in the field of precision machinery because it can provide precise position control and good repeatability of movement. Stepper motors are very suitable for applications that require positioning accuracy, such as precise positioning and movement of molds.

[0077] Servo motors: Servo motors provide high dynamic response and high-precision position, velocity, and acceleration control, making them suitable for scenarios requiring fast response and high-precision control. They are often used to control complex motion sequences, such as pressurization and precise movement in molding machines.
