Description

Technical Field

[0001] This application relates to the field of resin lens manufacturing technology, and in particular to a photocuring molding device for resin lenses. Background Technology

[0002] In the eyewear manufacturing industry, resin lenses hold a dominant market position due to their numerous advantages, including lightweight construction, excellent impact resistance, and superior light transmittance, making them a widely favored product among consumers. In the resin lens production process, the photocuring stage is crucial, as its quality directly and significantly affects the final lens performance, such as optical accuracy and physical stability, thus impacting whether the lens can meet consumers' demands for clear vision and comfortable wearing experience.

[0003] However, current commonly used resin lens photocuring equipment has revealed many drawbacks in actual production applications. The production process generally involves placing a mold containing liquid resin in a heating device for preheating. After preheating, the mold must be manually transferred to a curing device for curing. Once curing is complete, the cured mold must again be manually moved to a cooling device for cooling. In this production mode, the transfer of the mold between different devices is extremely cumbersome, consuming a large amount of manpower. Furthermore, manual operation is prone to errors and uncertainties, easily causing damage to the mold or lens due to improper handling. At the same time, the frequent transfers severely affect the continuity and smoothness of the production process, resulting in low overall production efficiency and making it difficult to meet the demands of large-scale, high-efficiency production. Utility Model Content

[0004] In order to improve the continuity and smoothness of the resin lens production process and increase the production efficiency of resin lenses, this application provides a photocuring molding device for resin lenses.

[0005] The photocuring molding equipment for resin lenses provided in this application adopts the following technical solution:

[0006] A photocuring molding apparatus for resin lenses, comprising:

[0007] Turntable frame;

[0008] An annular conveyor plate is mounted on the turntable frame. The annular conveyor plate is equipped with multiple tooling fixtures for carrying molds, and each tooling fixture is provided with a light-transmitting part.

[0009] A drive assembly is mounted on the turntable frame and is connected to the annular conveyor disk for driving the annular conveyor disk to move continuously or stepwise along an annular path.

[0010] And a preheating station, a curing station, a cooling station, and a loading / unloading station are sequentially arranged along the movement direction of the annular conveyor plate;

[0011] The preheating station is used to heat the mold before curing. The curing station is equipped with at least one set of curing light sources. The light emitted by the curing light sources is directed toward the light-transmitting part of the station to light-cur the resin in the mold. The cooling station is used to cool the cured mold. The loading and unloading station is used to unload the mold that has completed lens curing and cooling, and install the mold to be cured.

[0012] By adopting the above technical solution, the rotary table frame, the annular conveyor, and the multiple workstations enable automated production line operation of the resin lens photocuring molding process. The preheating station preheats the mold to bring the resin to a suitable curing temperature, improving curing quality. The curing station uses a curing light source to photocur the resin, achieving lens molding. The cooling station rapidly cools the cured mold, shortening the production cycle. The loading and unloading stations facilitate mold replacement, improving production efficiency and overall enhancing the quality and efficiency of resin lens photocuring molding.

[0013] Optionally, the curing station includes a first curing light source and a second curing light source respectively disposed above and below the annular conveyor plate. The first curing light source and the second curing light source are configured to emit light simultaneously to achieve synchronous curing of both sides of the mold.

[0014] By adopting the above technical solution, first and second curing light sources are respectively set above and below the annular conveyor plate and emit light simultaneously, achieving synchronous curing of both sides of the mold. This design allows the resin lens to be illuminated on both sides simultaneously during the curing process, resulting in more uniform curing. It can effectively reduce problems such as uneven stress and deformation caused by single-sided curing, and improve the optical performance and quality stability of the lens.

[0015] Optionally, the turntable frame is equipped with a controller corresponding to the curing station. The first curing light source and / or the second curing light source are ultraviolet lamps and are electrically connected to the controller, which controls their on / off state and emission sequence.

[0016] By adopting the above technical solution, an ultraviolet lamp is used as the curing light source and electrically connected to a controller. The controller precisely controls the on / off state and emission sequence of the ultraviolet lamp. This allows for precise adjustment of the light exposure time and intensity according to the characteristics of different resin materials and curing requirements, achieving optimal curing results while improving energy efficiency and reducing unnecessary energy consumption.

[0017] Optionally, the preheating station includes a preheating shell and an infrared heating device disposed within the preheating shell.

[0018] By adopting the above technical solution, the preheating station is equipped with a preheating shell and an infrared heating device. The infrared heating device can quickly and evenly heat the mold. The preheating shell plays a role in heat preservation, reducing heat loss, improving heating efficiency, and enabling the mold to quickly reach the appropriate curing temperature. This ensures that the resin is in a good physical state before curing, which is beneficial to improving the curing quality.

[0019] Optionally, the cooling station includes a cooling housing and a cooling fan located outside the cooling housing, the cooling fan being used to deliver cooling airflow into the cooling housing.

[0020] By adopting the above technical solution, the cooling station consists of a cooling shell and an external cooling fan. The cooling fan delivers cooling airflow into the cooling shell, which can quickly remove the heat from the mold and achieve rapid cooling. This cooling method is highly efficient, effectively shortens the production cycle, and ensures that the lens does not develop defects such as cracks due to excessively rapid temperature changes during the cooling process, thereby improving product quality.

[0021] Optionally, the tooling includes a base embedded in an annular conveyor plate, the base being used to support the mold, the light-transmitting part being disposed on the base, the base being provided with grippers for fixing the mold placed on the base during processing, and the base being provided with a control component for controlling the opening and closing of the grippers.

[0022] By adopting the above technical solution, a base for mounting the mold is set at each station of the annular conveyor. The base is equipped with a light-transmitting part, grippers, and control components. The light-transmitting part ensures that the light from the curing light source can smoothly illuminate the resin inside the mold; the grippers are used to fix the mold during processing to prevent mold movement from affecting processing accuracy; the control components can easily control the opening and closing of the grippers, facilitating the installation and disassembly of the mold and improving the convenience and efficiency of production operations.

[0023] Optionally, the base is provided with a positioning groove for accommodating the mold, and the light-transmitting part is located at the bottom of the positioning groove;

[0024] The gripper includes a limiting seat, which is movably connected to the base via a transmission component. The limiting seat can move toward or away from the positioning groove. When the positioning groove extends into the positioning groove, the mold can be confined within the positioning groove. The base is provided with an elastic component for pushing the limiting seat toward the positioning groove.

[0025] By adopting the above technical solution, a positioning groove is set on the base, and the light-transmitting part is at the bottom of the positioning groove, which facilitates the precise positioning and placement of the mold and ensures accurate illumination of the curing light; the gripper achieves automatic limiting function through the limiting seat, transmission component and elastic component. When the limiting seat extends into the positioning groove, it can stably limit the mold in the positioning groove, ensuring the stability of the mold during processing; the elastic component provides pre-push force, enabling the gripper to automatically clamp the mold, simplifying the operation process and improving production efficiency.

[0026] Optionally, the transmission component includes a first connecting rod and a second connecting rod that are intersected and hinged to each other. One end of the first connecting rod is hinged to the base, and the other end is rotatably connected to a first slider. The first slider is slidably disposed on the limiting seat. One end of the second connecting rod is hinged to the limiting seat, and the other end is rotatably connected to a second slide block. The second slide block is slidably disposed on the base.

[0027] A push rod is slidably disposed on the base, the sliding direction of the push rod being perpendicular to the sliding direction of the limiting seat on the base. The second slide is fixedly connected to the push rod. The elastic element is disposed between the push rod and the base, and is used to apply a pre-push force to the push rod so as to push the limiting seat to move toward the positioning groove.

[0028] By adopting the above technical solution, the transmission component uses a first and second linkage structure that intersects and hinges with each other. Combined with the sliding arrangement of the slider and slide block on the base, and the cooperation of the push rod and elastic element, this enables flexible movement of the gripper limit seat. This structure makes the opening and closing action of the gripper smoother and more reliable, and allows for precise control of the movement distance of the limit seat, thereby better fixing and releasing the mold and improving the stability and reliability of the equipment operation.

[0029] Optionally, the push rod extends out of the base, and a push block is provided on the loading / unloading station. When the base moves to the loading / unloading position, the push block pushes the push rod, and drives the limiting seat to move away from the positioning groove through the first connecting rod and the second connecting rod.

[0030] By adopting the above technical solution, the push rod extends out of the base, and a push block is set at the loading and unloading station. When the base moves to the loading and unloading position, the push block pushes the push rod, which drives the limit seat to move away from the positioning groove through the linkage transmission, realizing the automatic release of the gripper from the mold. This design automates the loading and unloading process, eliminating the need for manual operation of the gripper, improving production efficiency, and reducing the impact of human factors on the production process.

[0031] Optionally, a connecting frame is slidably provided on the lower end surface of the base, and a support plate is fixedly connected to the inner wall of the connecting frame. When the support plate is located below the positioning groove, it is used to support the mold in the positioning groove. The connecting frame is fixedly connected to the push rod. The movement of the push rod can drive the support plate to gradually move away from below the positioning groove, thereby relieving the supporting effect on the mold.

[0032] The loading and unloading station includes a loading area and an unloading area. Push blocks are respectively set as loading push blocks and unloading push blocks corresponding to the loading area and the unloading area. The unloading push block is used to push the push rod, causing the gripper to open, and the support plate to disengage from below the positioning groove. The loading push block is used to push the push rod, causing the gripper to open, and the support plate is located below the positioning groove.

[0033] By adopting the above technical solution, a sliding connecting frame and a support plate are set on the lower end face of the base, and the connecting frame is fixedly connected to the push rod. The movement of the push rod can cause the support plate to gradually detach from or be positioned below the positioning groove, cooperating with the loading and unloading push blocks at the loading and unloading stations. During unloading, the unloading push block pushes the push rod, causing the grippers to release the mold and the support plate to detach from below the positioning groove, facilitating mold unloading; during loading, the loading push block pushes the push rod, causing the grippers to release the mold and the support plate to be positioned below the positioning groove, facilitating the placement of new molds. This structure further optimizes the loading and unloading process, improves the accuracy and efficiency of loading and unloading, and ensures the continuity and stability of the production process.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The setup of the turntable frame, the ring conveyor, and multiple workstations enables automated assembly line operation of the resin lens photocuring molding process, improving the continuity and smoothness of the resin lens production process, and thus improving the production efficiency of resin lenses.

[0036] 2. The design of double-sided synchronous curing is adopted. The curing light sources set at the top and bottom simultaneously irradiate the two surfaces of the mold, which ensures the uniformity of curing inside and on the surface of the resin lens, effectively improving product quality and optical performance.

[0037] 3. The tooling integrates automatic clamping and support functions. Through the cooperation of the linkage mechanism and elastic elements, it achieves automatic locking of the mold during processing and automatic release at the loading and unloading stations. This structure is stable and reliable, requires no additional power source, simplifies the equipment structure, and reduces costs. Attached Figure Description

[0048] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0049] This application discloses a photocuring molding apparatus for resin lenses. For example... Figure 1 and Figure 2The photocuring equipment for resin lenses includes a turntable frame 10, an annular conveyor plate 11, and a drive assembly 60. The turntable frame 10 serves as the supporting frame for the entire equipment, providing a stable mounting base for other components. The annular conveyor plate 11 is horizontally rotatable on the turntable frame 10. Preheating stations 20, curing stations 30, cooling stations 40, and loading / unloading stations 52 are evenly distributed on the turntable frame 10 corresponding to the rotation direction of the annular conveyor plate 11. Multiple tooling fixtures 70 for supporting molds 12 are evenly distributed on the annular conveyor plate 11. Each tooling fixture 70 is equipped with a base 71, and the base 71 has a light-transmitting part, specifically a light-transmitting hole.

[0050] like Figure 3 and Figure 4 The drive assembly 60 includes a servo motor 61 and a reducer 62 fixedly connected to the turntable frame 10. The output end of the reducer 62 is connected to the annular conveyor disc 11 via a coupling 63, and the input end of the reducer 62 is connected to the output shaft of the servo motor 61. When the servo motor 61 is started, it can precisely control the annular conveyor disc 11 to move continuously or in a stepping motion along the annular path. In the stepping motion, it moves the distance of one tooling 70 at a time to ensure that the processing time of the mold 12 is stable at each station.

[0051] like Figure 2 and Figure 5 The preheating station 20 includes a preheating housing 21 fixedly connected to the turntable frame 10 and an infrared heating device 22 disposed within the preheating housing 21. The preheating housing 21 is made of heat-insulating material to reduce heat loss. The infrared heating device 22 consists of multiple infrared heating lamps evenly distributed inside the preheating housing 21. When the mold 12 moves to the preheating station 20 with the annular conveyor 11, the infrared rays emitted by the infrared heating lamps heat the mold 12. The preheating temperature can be precisely adjusted by a temperature controller, generally set between 60-80℃. The preheating time is adjusted according to the size of the mold 12 and the type of resin to ensure that the mold 12 and the resin inside reach the appropriate pre-curing temperature.

[0052] like Figure 2 and Figure 4The curing station 30 includes a mounting frame 31 mounted on the turntable frame 10. At least one set of curing light sources is mounted on the mounting frame 31. Each set of curing light sources includes a first curing light source 32 positioned above the annular conveyor plate 11 and a second curing light source 33 positioned below the annular conveyor plate 11, enabling simultaneous curing of both sides of the mold 12. Both the first curing light source 32 and the second curing light source 33 are high-power ultraviolet lamps with a wavelength range of 365-405nm, effectively stimulating the photoinitiator in the resin to induce a polymerization reaction. A controller is mounted on the mounting frame 31, electrically connected to the ultraviolet lamps. The controller uses a programmable logic controller (PLC) to precisely control the on / off state and emission sequence of the ultraviolet lamps. For example, the luminous intensity and emission time of the ultraviolet lamps can be set according to the curing characteristics of the resin; typically, the luminous intensity is 50-100mW / cm², and the emission time is 3-8 minutes. When the mold 12 enters the curing station 30, the controller simultaneously activates the first curing light source 32 and the second curing light source 33. The emitted ultraviolet light passes through the light-transmitting part on the base 71 to simultaneously cure the resin inside the mold 12 on both sides, which greatly improves the curing efficiency and quality.

[0053] like Figure 2 and Figure 6 The cooling station 40 includes a cooling housing 41 mounted on the turntable frame 10 and a cooling fan 42 located outside the cooling housing 41. The cooling housing 41 is made of metal and has good thermal conductivity. The cooling fan 42 is a centrifugal fan. When the cured mold 12 moves to the cooling station 40, the cooling fan 42 starts and delivers airflow into the cooling housing 41. Under the guidance of the cooling housing 41, the airflow is sprayed towards the mold 12, quickly removing heat from the mold 12 and the cured lens inside. The cooling time can be set according to the lens specifications and process requirements to ensure that the lens is completely cooled and shaped, avoiding deformation and other problems caused by excessive temperature in subsequent operations.

[0054] The loading / unloading station 52 includes a loading area 51 and an unloading area 52. The loading area 51 is used to install the mold 12 containing the resin solution to be cured, and the unloading area 52 is used to unload the mold 12 after the lens has been cured and cooled. The base 71 is provided with a positioning groove 72 for accommodating the mold 12, and a light-transmitting hole is provided at the bottom of the positioning groove 72. The gripper 73 includes one or more limiting seats 74. In this embodiment, there are two limiting seats 74, which are symmetrically arranged about the positioning groove 72. The limiting seats 74 are movably connected to the base 71 through a transmission member 90. The mold 12 includes a disc-shaped upper mold and a lower mold. The outer circumference of the lower mold is provided with a ring edge. The lower mold is located in the positioning groove 72. The limiting seats 74 move toward the positioning groove 72 and abut against the upper end of the ring edge to fix the position of the mold 12 in the positioning groove 72. This arrangement can reduce the obstruction of the resin material in the mold 12 by the tooling 70 during the ultraviolet curing process.

[0055] like Figure 7 and Figure 8 The transmission component 90 consists of a first connecting rod 91 and a second connecting rod 92 that are intersected and hinged together. One end of the first connecting rod 91 is hinged to the base 71, and the other end is rotatably connected to a first slider, which is slidably mounted on a limiting seat 74. One end of the second connecting rod 92 is hinged to the limiting seat 74, and the other end is rotatably connected to a second slide, which is slidably mounted on the base 71. The distance between the hinge axes of the two ends of the first connecting rod 91 is the same as the distance between the hinge axes of the two ends of the second connecting rod 92. Furthermore, the hinge axis between the first connecting rod 91 and the second connecting rod 92 is referred to as the connecting axis, which is located at the midpoint between the hinge axes of the two ends of the first connecting rod 91 and the second connecting rod 92.

[0056] A push rod 95 is slidably mounted on the base 71, with the sliding direction of the push rod 95 parallel to the radial direction of the annular conveyor disk 11. A second slide block is fixedly connected to the push rod 95. The push rods 95 corresponding to the two limiting seats 74 are interconnected. By moving the push rod 95, the two limiting seats 74 on the base 71 can be moved closer to or further away from each other. An elastic element 80 is also provided on the base 71. The elastic element 80 directly or indirectly pushes the limiting seats 74 toward the positioning groove 72. The elastic element 80 is a compression spring, located between the push rod 95 and the base 71. It applies a pre-push force to the push rod 95 to move away from the rotation axis of the annular conveyor disk 11, causing the two limiting seats 74 to move toward the positioning groove 72 in their natural state, thereby confining the mold 12 within the positioning groove 72.

[0057] like Figure 8 and Figure 9 A connecting frame 75 is slidably mounted on the lower end face of the base 71, and the sliding direction of the connecting frame 75 is parallel to the sliding direction of the push rod 95. A support plate 76 is fixedly connected to the inner wall of the connecting frame 75. When the support plate 76 is located below the positioning groove 72, it is used to support the mold 12 in the positioning groove 72. The connecting frame 75 is fixedly connected to the push rod 95. A push block is correspondingly provided on the loading and unloading station 52 to push the push rod 95 toward the rotation axis of the conveyor plate. The push block corresponding to the loading area 51 is called the loading push block 96, and the push block corresponding to the unloading area 52 is called the unloading push block 97. The pushing distance of the unloading push block 97 to the push rod 95 is greater than the pushing distance of the loading push block 96 to the push rod 95.

[0058] When the base 71 moves to the unloading area 52, the unloading push block 97 pushes the push rod 95 out of the base 71. The push rod 95 overcomes the pre-push force of the elastic element 80 and slides away from the positioning groove 72. Through the transmission action of the first link 91 and the second link 92, the limiting seat 74 moves away from the positioning groove 72. At the same time, the support plate 76 is disengaged from below the positioning groove 72, so that the mold 12 in the positioning groove 72 falls downward under the action of gravity. The operator can collect the mold 12 after the lens curing is completed by setting a receiving box below the unloading area 52.

[0059] When the base 71 moves to the loading area 51, the loading pusher 96 pushes the push rod 95, which in turn loosens the limiting seat 74. At this time, the support plate 76 partially resets and supports the mold 12 containing the resin solution to be cured on the support plate 76. The operator places the mold 12 on the support plate 76. The annular conveyor 11 moves the base 71 toward the preheating station 20. The push rod 95 resets under the action of the elastic element 80. Under the linkage of the first connecting rod 91 and the second connecting rod 92, the two limiting seats 74 move toward the positioning groove 72, fixing the mold 12 in the positioning groove 72. At the same time, the support plate 76 continues to support the mold 12, enhancing the stability of the mold 12 during processing.

[0060] The implementation principle of this application embodiment is as follows: After the equipment is started, the drive component 60 drives the annular conveyor plate 11 to start running, which drives the molds 12 on each tooling 70 to move with the annular conveyor plate 11. First, the mold 12 enters the preheating station 20 and is preheated under the action of the infrared heating device 22. After preheating, the mold 12 moves to the curing station 30 and is simultaneously cured on both sides under the simultaneous irradiation of the first curing light source 32 and the second curing light source 33. After curing, the mold 12 enters the cooling station 40 and is rapidly cooled under the action of the cooling fan 42. Finally, the mold 12 moves to the loading and unloading station 52, where it is first unloaded in the unloading area 52, and then a new mold 12 to be cured is installed in the loading area 51. The above process is then repeated to achieve continuous and efficient production of resin lenses.

[0061] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
