Description

Technical Field

[0001] This application relates to the field of manufacturing and processing technology, for example to a die-cutting system for optical glass and a method for controlling the die-cutting system. Background Technology

[0002] Optical lenses are a crucial component of smartphone imaging. The materials used in optical lenses fall into two main categories: plastic and glass. Plastic lenses are lightweight and inexpensive, making them more suitable for mass production; currently, plastic lenses are primarily used in the smartphone industry. Glass lenses have higher light transmittance and refractive index, but their manufacturing process is complex and costly; they are currently mainly used in camera production.

[0003] In recent years, to improve the optical performance of mobile phones, the amount of plastic lenses used in mobile phone lenses has been increasing. However, this has also led to problems such as increased lens thickness and reduced assembly yield. Glass lenses are superior to plastic lenses in terms of light transmission and refractive index. Replacing plastic lenses with glass lenses can not only reduce lens thickness and improve image quality, but also help improve production and assembly efficiency. As the market's demands for smartphone size, pixel count, and aperture continue to rise, mobile phone lenses are also gradually being upgraded and innovated. To meet the development of smartphones towards thinner, more multifunctional, and higher-precision designs, glass lenses will inevitably replace plastic lenses as the preferred choice for smartphone lenses.

[0004] Among the related technologies, a linearly arranged multi-station optical glass lens molding system is provided to realize the processing and production of glass lenses.

[0005] The following problems exist in the publicly disclosed implementation process:

[0006] Compared to camera lenses, mobile phone lenses are much smaller. Therefore, they cannot be molded and polished from a single piece of material like traditional fluorite or glass lenses. Instead, a linear arrangement optical glass lens molding system, with its compact spatial arrangement, cannot meet the demands of adding functional modules in the new molding processes required for mobile phone lenses. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a molding system for optical glass and a control method for the molding system, which can adapt to the processing requirements of new molding processes for mobile phone lenses and improve the processing efficiency of optical glass.

[0009] In some embodiments, the die-casting system for optical glass includes: a vacuum die-casting chamber, comprising a vacuum processing cavity and a plurality of processing stations, the plurality of processing stations being distributed circumferentially within the vacuum processing cavity; a plurality of servo loading systems disposed in the vacuum die-casting chamber, the plurality of servo loading systems including a plurality of loading ends located within the vacuum processing cavity, the plurality of loading ends being correspondingly disposed to at least a portion of the plurality of processing stations; and a conveying mechanism disposed in the vacuum die-casting chamber, located within the vacuum processing cavity, the conveying mechanism being used to move workpieces between the plurality of processing stations.

[0010] In some embodiments, a control method for a die-cutting system is used for a die-cutting system as described in any of the above embodiments. The control method includes: controlling the vacuum die-cutting chamber to open in response to an operating command; after placing the workpiece to be processed into the vacuum processing chamber, controlling the vacuum die-cutting chamber to close and controlling the conveying mechanism to operate so as to move the workpiece to be processed sequentially between multiple processing stations along the circumference of the vacuum processing chamber; and when the workpiece to be processed moves to each processing station, controlling the servo loading system corresponding to the processing station to operate so as to process the workpiece to be processed.

[0013] The die-cutting system disclosed herein is designed for the processing and production of mobile phone glass lenses by incorporating a vacuum die-cutting chamber with a vacuum processing cavity. Multiple processing stations are spaced apart along the circumference of the vacuum die-cutting chamber within the vacuum processing cavity. Furthermore, a conveying mechanism that coordinates with these circumferentially distributed processing stations enables a multi-station rotary die-cutting system for optical glass.

[0054] In some embodiments, combined with Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 7 As shown, a molding system 1 for optical glass is provided, comprising: a vacuum molding chamber 100, including a vacuum processing cavity 120 and a plurality of processing stations 130, the plurality of processing stations 130 being distributed circumferentially within the vacuum processing cavity 120; a plurality of servo loading systems 400, the plurality of servo loading systems 400 being disposed in the vacuum molding chamber 100, the plurality of servo loading systems 400 including a plurality of loading ends, the plurality of loading ends being located within the vacuum processing cavity 120, the plurality of loading ends being correspondingly disposed to at least a portion of the plurality of processing stations 130; and a conveying mechanism 200, disposed in the vacuum molding chamber 100, located within the vacuum processing cavity 120, the conveying mechanism 200 being used to move workpieces between the plurality of processing stations 130.

[0055] The die-casting system 1 for optical glass provided in this embodiment includes a vacuum die-casting chamber 100, multiple servo loading systems 400, and a conveying mechanism 200. The vacuum die-casting chamber 100 is configured with a vacuum processing cavity 120 and multiple processing stations 130 located within the vacuum processing cavity 120. The multiple processing stations 130 are distributed circumferentially at intervals along the vacuum die-casting chamber 100. The conveying mechanism 200 is disposed within the vacuum processing cavity 120 and is rotatable relative to the vacuum die-casting chamber 100. The multiple servo loading systems 400 include multiple loading ends that extend into the vacuum processing cavity 120, and some or all of the multiple processing stations 130 are correspondingly arranged with respect to the multiple loading ends.

[0056] The die-cutting system 1 disclosed herein is suitable for the processing and production of mobile phone glass lenses by providing a vacuum die-cutting chamber 100 with a vacuum processing cavity 120. Multiple processing stations 130 are spaced apart along the circumference of the vacuum die-cutting chamber 100 within the vacuum processing cavity 120. Furthermore, a conveying mechanism 200 is provided to cooperate with the multiple circumferentially distributed processing stations 130, thereby realizing a multi-station rotary die-cutting system 1 for optical glass. Multiple servo loading systems 400, along with some or all of the processing stations 130 and multiple loading ends, meet the processing requirements of the multiple processing stations 130. Through the cooperation of the conveying mechanism 200, the multiple servo loading systems 400, and the multiple processing stations 130, the workpiece is sequentially rotated through the multiple processing stations 130 to complete the corresponding processing steps, improving processing efficiency. The die-cutting system 1 provided in this disclosure can provide a vacuum environment for optical glass processing and can also set up a rotating arrangement of processing stations 130 for processing steps, thereby improving the processing and production efficiency of optical lenses for mobile phones.

[0057] Optionally, the number of processing stations 130 is equal to the number of loading ends. The processing stations 130 are set up one-to-one with the loading ends so that the loading ends cooperate with the processing stations to complete the processing of optical glass.

[0058] Optionally, the number of processing stations 130 is greater than the number of loading ends. Furthermore, the number of processing stations 130 can be odd or even. The number of loading ends can be set according to the processing requirements of the optical glass. Having more processing stations than loading ends allows for meeting the processing needs of different types of optical glass, or the processing needs of optical glass for different application scenarios, thereby expanding the application range of the modular system.

[0059] It should be noted that the number of processing stations 130, as well as the number and type of loading ends, can be specifically set according to the characteristics of the specific optical glass processing procedures and application scenarios, which will not be elaborated here.

[0060] Optionally, combined Figures 3 to 7 As shown, the vacuum molding chamber 100 also includes a lifting mechanism 300. The lifting mechanism 300 is disposed within the vacuum processing chamber 120 and includes a loading station 310 and a unloading station 320. The loading station 310 and the unloading station 320 are located between two adjacent processing stations 130 among a plurality of processing stations 130. The lifting mechanism 300 can rise or fall to drive the loading station 310 and the unloading station 320 to reciprocate between the working position and the loading / unloading position.

[0061] In this embodiment, a lifting mechanism 300 is provided within the vacuum processing chamber 120 of the vacuum molding chamber 100. The lifting mechanism 300 is disposed within the vacuum molding chamber 100 and is capable of rising or falling relative to the vacuum molding chamber 100. The lifting mechanism 300 includes a loading station 310 for loading and a unloading station 320 for unloading. Furthermore, the loading station 310 and the unloading station 320 are arranged adjacent to each other along the circumference of the vacuum molding chamber 100, and are located between two adjacent processing stations 130 among a plurality of processing stations 130. By providing the lifting mechanism 300 within the vacuum processing chamber 120, workpieces to be processed are input into the processing stations 130 within the vacuum processing chamber 120. The lifting mechanism 300 is also used for unloading workpieces processed by the plurality of processing stations 130. By setting up a lifting mechanism 300 to drive the loading station 310 and the unloading station 320 to reciprocate between the working position and the loading / unloading position, the efficiency of loading and unloading is improved. Through the lifting mechanism 300, the conveying mechanism 200 and multiple processing stations 130, continuous processing of workpieces is realized, improving the continuity of processing steps and enabling continuous processing of multiple processing steps, thereby improving the production efficiency of optical glass.

[0062] Optionally, combined Figure 4 , Figure 5 and Figure 6 As shown, the lifting mechanism 300 includes: a lifting platform 330, a loading station 310 and a unloading station 320 disposed on the lifting platform 330; and a lifting part 340 disposed in the vacuum processing chamber 120. The lifting part 340 is connected to the lifting platform 330 and is used to drive the lifting platform 330 to reciprocate between the working position and the loading / unloading position. The working position is located above the loading / unloading position along the height direction of the vacuum molding chamber 100.

[0063] In this embodiment, the lifting unit 340 is disposed in the vacuum molding chamber 100. The lifting platform 330 rises or falls relative to the vacuum molding chamber 100 under the drive of the lifting unit 340. By adjusting the height of the lifting platform 330, the loading station 310 and unloading station 320 on the lifting platform 330 can cooperate with multiple processing stations 130 to achieve continuity of loading, processing and unloading.

[0064] Specifically, driven by the lifting unit 340, the lifting platform 330 can reciprocate between the working position and the loading / unloading position. When the lifting platform 330 is in the working position, the loading station 310 and unloading station 320 on the lifting platform 330 are at the same height as multiple processing stations 130. In this way, the conveying mechanism 200 can move the workpiece to be processed on the loading station 310 to an adjacent processing station 130 to begin the processing step. Simultaneously, the conveying mechanism 200 can also move the processed workpiece from the last processing station 130 adjacent to the unloading station 320 to the unloading station 320. After the workpiece movement is completed, the lifting unit 340 drives the lifting platform 330 to descend to the loading / unloading position.

[0065] Optionally, combined Figure 12 As shown, the multiple processing stations 130 include a mold preheating station 132, a mold engraving station 134, a mold engraving pressure holding station 136, and a cooling station 138; wherein, the multiple processing stations 130, the loading station 310, and the unloading station 320 are distributed in the following order along the circumference of the vacuum mold engraving chamber 100: loading station 310, mold preheating station 132, mold engraving station 134, mold engraving pressure holding station 136, cooling station 138, and unloading station 320.

[0066] In this embodiment, for the optical glass material molding technology, multiple processing stations 130 are set up, and the multiple processing stations 130, loading station 310 and unloading station 320 are arranged sequentially at intervals along the circumferential direction of the vacuum molding chamber 100, so as to realize continuous processing of the workpiece to be processed, thereby improving processing efficiency and processing quality.

[0067] In practical applications, the types of multiple processing stations 130 are not limited to: mold preheating station 132, die-cutting station 134, die-cutting pressure holding station 136, and cooling station 138. The specific types of processing stations can be set according to specific application scenarios, which will not be elaborated here.

[0068] Specifically, the multiple processing stations 130 include a mold preheating station 132, a mold engraving station 134, a mold engraving pressure holding station 136, and a cooling station 138. The order in which they are distributed along the circumference of the vacuum mold engraving chamber 100 is as follows: loading station 310, mold preheating station 132, mold engraving station 134, mold engraving pressure holding station 136, cooling station 138, and unloading station 320.

[0069] Optionally, the servo loading system 400 adopts a high-precision servo loading system 400 integrating a grating ruler, servo encoder, and force sensor to improve the processing accuracy of optical glass.

[0070] Optionally, the die-cutting system 1 also includes resistance heating elements disposed in the vacuum die-cutting chamber 100. There are multiple resistance heating elements. These multiple resistance heating elements are respectively disposed at the preheating station, the die-cutting station 134, and the die-cutting pressure-holding station 136, to heat the mold at the preheating station, the mold at the die-cutting station 134, and the mold at the die-cutting pressure-holding station 136, respectively, to meet the temperature requirements of different processes.

[0071] Among them, optical glass material molding technology is an advanced processing technology that uses high-precision optical molds to press optical glass materials into shape in one step. This technology requires heating the optical glass to a specific temperature (typically between the transition temperature and softening temperature) in an optical glass lens molding system 1. Then, by applying pressure to both the mold and the pre-shaped optical glass, plastic strain is induced in the optical glass, thereby replicating the structure on the mold onto the surface of the optical glass material. During this process, the mold and the surface of the optical glass material remain in contact throughout. Therefore, after the processing is completed, the resulting optical glass component requires no further grinding or polishing and can be used directly.

[0072] Optionally, combined Figure 7 and Figure 12 As shown, multiple processing stations 130, loading stations 310, and unloading stations 320 are evenly distributed along the circumference of the transmission mechanism. The included angle between any two adjacent stations is 60°. The number of multiple conveyor components 250 is the same as the number of stations, with one conveyor component 250 corresponding to each station. This allows for the synchronous movement of workpieces at multiple stations, improving the continuity and efficiency of the processing steps.

[0073] Optionally, combined Figures 10 to 12 As shown, the vacuum molding chamber 100 also includes a chamber body 110 and a base 111. The chamber body 110 includes a loading port 114 and a unloading port 115; the chamber body 110 is disposed on the base 111 to enclose a vacuum processing cavity 120. Both the loading port 114 and the unloading port 115 are connected to the vacuum processing cavity 120. Specifically, when the lifting mechanism 300 is raised to the working position, the loading station 310 and the unloading station 320 are located on the same plane as the multiple processing stations 130; when the lifting mechanism 300 is lowered to the loading / unloading position, the loading station 310 and the unloading station 320 correspond to the loading port 114 and the unloading port 115, respectively.

[0074] In this embodiment, a vacuum processing chamber 120 is formed by the chamber 110 and the seat 111, providing a vacuum environment for the processing of optical glass. When both the loading port 114 and the unloading port 115 are connected to the vacuum processing chamber 120 at the loading / unloading positions, the loading station 310 of the lifting platform 330 corresponds to the loading port 114 of the vacuum molding chamber 100, and the next batch of workpieces is placed at the loading station 310 through the loading port 114. Simultaneously, the unloading station 320 corresponds to the unloading port 115 of the vacuum molding chamber 100, and the completed workpieces on the unloading station 320 are removed from the vacuum molding chamber 100 through the unloading port 115.

[0075] The loading and unloading processes are carried out simultaneously through the loading port 114 and the unloading port 115 to improve processing efficiency.

[0076] Optionally, the chamber 110 includes a first pipe joint and a second pipe joint, which are respectively connected to the vacuum processing chamber 120.

[0077] Optionally, combined Figure 11 As shown, the chamber 110 includes a barrel 112 and a top cover 113. The barrel 112 is disposed on the base 111, and the top cover 113 covers the open end of the barrel 112. The base 111, the barrel 112, and the top cover 113 enclose a vacuum processing chamber 120. A conveying mechanism 200 and a lifting mechanism 300 are disposed on the base 111.

[0078] Furthermore, the feed inlet 114 and the discharge inlet 115 are located on the barrel wall of the barrel body 112. Connecting joints are provided on the outer sides of the feed inlet 114 and the discharge inlet 115, protruding outwards from the barrel wall. These connecting joints enable connection to the vacuum processing assembly of the material conveying mechanism. A first pipe joint and a second pipe joint are also provided on the barrel body 112.

[0079] Furthermore, the servo loading system 400 is disposed on the upper cover 113 and located on the outer wall of the upper cover 113.

[0080] Furthermore, the die-cutting system 1 also includes multiple upper dies and multiple lower dies. The multiple upper dies and multiple lower dies are arranged in a one-to-one correspondence. The multiple lower dies are respectively arranged at multiple processing stations 130, and are arranged in a one-to-one correspondence. The multiple upper dies are located on the inner wall of the upper cover 113, within the vacuum processing chamber 120. A high-precision servo loading system 400 located outside the vacuum processing chamber 120 is connected to the multiple upper dies to drive the multiple upper dies and multiple lower dies to cooperate in completing the processing steps.

[0081] Optionally, the die-cutting system 1 also includes a vacuum pumping component connected to the first pipe connector for evacuating the vacuum processing chamber 120.

[0082] Optionally, the die-cutting system 1 also includes a nitrogen supply unit. The nitrogen supply unit is connected to the vacuum processing chamber 120 via a second pipe connector. The nitrogen supply unit is used to break the vacuum in the vacuum processing chamber 120.

[0083] Optionally, the vacuum die-cutting chamber 100 further includes a rotary table 260. The rotary table 260 is disposed on the base 111 and includes a central hole. A plurality of processing stations 130 are disposed on the rotary table 260 and distributed around the central hole. A conveying mechanism 200 is mounted on the central hole and is rotatable relative to the rotary table 260 for moving workpieces between the plurality of processing stations 130.

[0084] In this embodiment, a rotary table 260 is set up to support the conveying mechanism 200 and multiple processing stations 130, so as to realize the process arrangement in the circumferential direction and improve the processing efficiency.

[0085] Optionally, combined Figure 1 , Figure 3 and Figure 7 As shown, the conveying mechanism 200 includes: a first rotating body 210, which is rotatable relative to the vacuum molding chamber 100, and includes a through hole; a second rotating body 230, which is mounted in the through hole and is rotatable relative to the first rotating body 210, and includes a mounting hole 232 located on the periphery of the through hole; and a conveying member 250, which is mounted on the first rotating body 210, and includes a movable part 251 and a gripping part 252, which is connected to the movable part 251. The movable part 251 is disposed in the mounting hole 232 and is movable along the mounting hole 232. During the relative rotation of the first rotating body 210 and the second rotating body 230, the movable part 251 is movable along the mounting hole 232 to drive the gripping part 252 to move.

[0086] In this embodiment, the conveying mechanism 200 includes a first rotating body 210, a second rotating body 230, and a conveying member 250. The second rotating body 230 is mounted on the first rotating body 210 and is rotatable relative to the first rotating body 210. A mounting hole 232 is provided along the circumference of the second rotating body 230. The conveying member 250 includes a movable part 251 and a gripping part 252 connected to each other.

Furthermore, as the movable part 251 moves along the mounting hole 232, it drives the gripping part 252 to move, thereby achieving the function of gripping the workpiece.

[0087] By employing the conveying mechanism 200 provided in this disclosure, the second rotating body 230 moves relative to the first rotating body 210. During the movement of the second rotating body 230, the movable part 251 of the transmission component moves along the mounting hole 232, thereby driving the clamping part 252 connected to the movable part 251 to move, thereby realizing the gripping of the workpiece.

[0088] The conveying mechanism 200 provided in this disclosure has rotation and gripping functions. By integrating the gripping and rotation functions into one unit, the space occupied is reduced, the space utilization rate is improved, the control system is simplified, and the docking of two independent systems is avoided.

[0089] Optionally, the first rotating body 210 is installed in the center hole of the rotary table 260, and the first rotating body 210 is rotatable relative to the rotary table 260. Multiple processing tables are spaced apart along the circumference of the rotary table 260. By setting multiple processing tables in conjunction with multiple conveying components 250 set on the first rotating body 210, the first rotating body 210 and the second rotating body 230 rotate relative to the rotary table 260, thereby moving the workpiece from the current corresponding workstation to the next workstation via the conveying components 250. This enables the workpiece to move sequentially between multiple processing tables, achieving simultaneous multi-process processing in the circumferential direction, thus expanding the applicable scenarios of the conveying mechanism 200 and improving processing efficiency.

[0090] Optionally, multiple processing stations 130 are set on multiple processing tables, with each processing station 130 corresponding to one processing table.

[0091] Optionally, combined Figure 1 and Figure 7 As shown, the mounting hole 232 is a strip-shaped hole, and the extension direction of the strip-shaped hole extends along the circumference of the second rotating body 230.

[0092] In this embodiment, the mounting hole 232 is configured as a strip-shaped hole to provide movement space for the movable part 251. The strip-shaped hole extends circumferentially along the second rotating body 230, and the distances from the first and second ends of the mounting hole 232 to the center of the second rotating body 230 are unequal, resulting in an inclined arrangement of the strip-shaped hole. The strip-shaped hole guides the movable part 251, thereby driving the gripping part 252 to move.

[0093] Optionally, the mounting hole 232 may include a straight strip hole, an arc-shaped strip hole, or a zigzag strip hole, which can enable the movable part 251 to slide along the mounting hole 232, and the distance between the moving trajectory of the movable part 251 from the first end to the second end of the mounting hole 232 and the rotation center of the second rotating body 230 may be different.

[0094] In some embodiments, the distance between the rotation center of the second rotating body 230 and the movement trajectory of the movable part 251 from the first end of the mounting hole 232 to the second end gradually increases.

[0095] In this embodiment, the mounting hole 232 includes a first end and a second end. The movable part 251 can move from the first end to the second end of the mounting hole 232, or from the second end to the first end. The distance from the first end to the rotation center of the second rotating body 230 is not equal to the distance from the second end to the rotation center of the second rotating body 230. That is, the distance between the moving trajectory of the movable part 251 from the first end to the second end of the mounting hole 232 and the rotation center of the second rotating body 230 increases. Thus, the line connecting the first end and the second end is inclined relative to the circumference of the second rotating body 230, and as the movable part 251 moves along the mounting hole 232, it also displaces radially along the second rotating body 230, thereby driving the gripping part 252 to move and achieve gripping.

[0096] In some embodiments, combined with Figure 1 and Figure 2 As shown, the distance between the rotation center of the second rotating body 230 and the movement trajectory of the movable part 251 from the first end of the mounting hole 232 to the second end gradually decreases.

[0097] In this embodiment, the mounting hole 232 includes a first end and a second end. The movable part 251 can move from the first end to the second end of the mounting hole 232, or from the second end to the first end. The distance from the first end to the rotation center of the second rotating body 230 is not equal to the distance from the second end to the rotation center of the second rotating body 230. In this embodiment, the distance between the moving trajectory of the movable part 251 from the first end to the second end of the mounting hole 232 and the rotation center of the second rotating body 230 gradually decreases. Thus, the line connecting the first end and the second end is inclined relative to the circumference of the second rotating body 230, and as the movable part 251 moves along the mounting hole 232, it also displaces radially along the second rotating body 230, thereby driving the gripping part 252 to move and achieve grasping.

[0098] Optionally, combined Figure 2 As shown, the clamping part 252 includes: a guide member 253 disposed on the first rotating body 210, the guide member 253 being slidable relative to the first rotating body 210, and the guide member 253 being connected to the movable part 251; and a clamping member 254 slidably connected to the guide member 253. During the movement of the movable part 251 along the mounting hole 232, the guide member 253 is driven to slide relative to the first rotating body 210, thereby driving the clamping member 254 to move for clamping or releasing the workpiece.

[0099] In this embodiment, the clamping part 252 includes a guide 253 and a clamping member 254. The guide 253 is connected to the movable part 251, and the clamping member 254 is slidably connected to the guide 253. The guide 253 is slidable relative to the first rotating body 210. During the movement of the movable part 251 along the mounting hole 232, it is displaced radially along the second rotating body 230, thereby causing the guide 253 to slide relative to the first rotating body 210. The sliding of the guide 253 causes the clamping member 254 to slide relative to the guide 253, thereby clamping or releasing the workpiece.

[0100] Optionally, combined Figure 2 As shown, the guide member 253 is provided with a first guide groove 2533 and a second guide groove 2535 that are relatively inclined. The clamping member 254 includes a first clamping body 2541 and a second clamping body 2542. The first clamping body 2541 is slidably connected to the first guide groove 2533. The second clamping body 2542 is slidably connected to the second guide groove 2535. During the sliding process of the guide member 253 relative to the first rotating body 210, it drives the first clamping body 2541 to slide along the first guide groove and the second clamping body 2542 to slide along the second guide groove 2535, for clamping or releasing workpieces.

[0101] In this embodiment, the guide member 253 includes a first guide groove 2533 and a second guide groove 2535 that are relatively inclined. The clamping member 254 includes a first clamping body 2541 and a second clamping body 2542 that are adjacent to each other and cooperate with each other. The first clamping body 2541 is slidably connected to the first guide groove 2533, and the second clamping body 2542 is slidably connected to the second guide groove 2535. When the first clamping body 2541 and the second clamping body 2542 slide along a first sliding direction, the first clamping body 2541 and the second clamping body 2542 move closer to each other to achieve cooperating clamping of the workpiece. When the first clamping body 2541 and the second clamping body 2542 slide along a second sliding direction, the first clamping body 2541 and the second clamping body 2542 move further apart to achieve releasing the workpiece. The first sliding direction and the second sliding direction are opposite in direction.

[0102] Optionally, combined Figure 2 As shown, the transmission component also includes: a mounting base 255, which is mounted on the first rotating body 210, and a guide 253, which is mounted on the mounting base 255 and can slide relative to the mounting base 255.

[0103] In this embodiment, the transmission component further includes a mounting base 255 disposed on the first rotating body 210. A guide member 253 is mounted on the first rotating body 210 and is slidable relative to the mounting base 255. Thus, as the movable part 251 moves along the mounting hole 232, it drives the guide member 253 to slide relative to the mounting base 255, thereby driving the gripping member 254 to move for gripping or releasing the workpiece. By employing the transmission component 250 provided in this disclosure in cooperation with the second rotating body 230, the mechanically driven gripping member 252 is used to grip or release the workpiece, reducing power consumption compared to related technologies that use motors and cylinders as driving components.

[0104] Optionally, combined Figure 2 As shown, the guide member 253 includes: a guide rod 2531, which passes through the mounting base 255 and is slidable relative to the mounting base 255; one end of the guide rod 2531 is connected to the movable part 251; a guide block 2532 is disposed at the other end of the guide rod 2531, and two guide grooves 2533, which are inclined relative to each other, are disposed on the guide block 2532; and a spring 2534 is sleeved on the guide rod 2531 and is located between the movable part 251 and the mounting base 255.

[0105] In this embodiment, the guide member 253 includes a guide rod 2531, a guide block 2532, and a spring 2534. The mounting base 255 includes a guide hole, through which the guide rod 2531 passes and is slidably connected to the mounting base 255. Both ends of the guide rod 2531 are connected to the movable part 251 and the guide block 2532, respectively. The spring 2534 is sleeved on the guide rod 2531 and located between the movable part 251 and the mounting base 255. A guide groove 2533 is provided in the guide block 2532. The movable part 251 moves along the mounting hole 232, causing the guide rod 2531 to slide relative to the mounting base 255. The guide rod 2531 causes the guide block 2532 to slide relative to the clamping part 252, thereby clamping or releasing the workpiece. During the sliding process of the guide rod 2531 relative to the mounting base 255, the spring 2534 is compressed, and the guide rod 2531 returns to its original position under the action of the spring 2534. In this way, the coordinated operation of the transmission component and the second rotating body 230 enables the gripping or release of the workpiece. By replacing the drive of the power component with a mechanical structure, energy consumption is reduced, and structural integration is achieved.

[0106] Optionally, combined Figure 1 As shown, the conveying mechanism 200 further includes: a first driving member 220, the output end of which is connected to the first rotating body 210 for driving the first rotating body 210 to rotate; and a second driving member 240, the output end of which is connected to the second rotating body 230 for driving the second rotating body 230 to rotate.

[0107] In this embodiment, the conveying mechanism 200 further includes a first driving member 220 and a second driving member 240 for driving the first rotating body 210 and the second rotating body 230, respectively. The first driving member 220 drives the first rotating body 210 to rotate, and the second driving member 240 drives the second rotating body 230 to rotate, so as to adjust the position of the transmission member and drive the transmission member to perform the workpiece clamping and releasing actions.

[0108] Optionally, the conveying mechanism 200 further includes a controller. The controller is connected to the first drive member 220 and the second drive member 240. The controller, according to an operating command, controls the second drive member 240 to rotate in a first direction, thereby moving the conveyor member 250 from the first end of the mounting hole 232 to the second end. Then, it controls the first drive member 220 and the second drive member 240 to rotate synchronously by a preset angle, and finally controls the second drive member 240 to rotate in a second direction, thereby moving the transmission member from the second end of the mounting hole 232 to the first end. The first and second directions are opposite, and the distance from the first end to the rotation center of the second rotating body 230 is greater than the distance from the second end to the rotation center of the second rotating body 230.

[0109] In this embodiment, the controller controls the operation of the first drive member 220 and the second drive member 240 to drive the first rotating body 210 and the second rotating body 230 to rotate. Specifically, in response to the operation command, the second drive member 240 is first controlled to drive the second rotating body 230 to rotate in a first direction, so that the mounting hole 232 opened in the second rotating body 230 rotates, thereby causing the movable part 251 to move relative to the mounting hole, so that the movable part 251 moves from the first end of the mounting hole 232 to the second end, driving the guide rod 2531 to move towards the center of the second rotating body 230, thereby driving the clamping part 252 to clamp the workpiece. After the workpiece is clamped, the first drive member 220 and the second drive member 240 are controlled to rotate synchronously by a preset angle to the next station. After moving to the next workstation, the second drive unit 240 is controlled to drive the second rotating body 230 to rotate in the second direction, thereby rotating the mounting hole 232. This causes the movable part 251 located within the mounting hole 232 to move from the second end of the mounting hole 232 to the first end. Since the second end of the mounting hole 232 is closer to the edge of the second rotating body 230 relative to the first end, the guide rod 2531 moves away from the center of the second rotating body 230, thereby causing the first gripping body 2541 and the second gripping body 2542 of the gripping part 252 to separate, completing the release of the workpiece. By repeatedly controlling the first drive unit 220 and the second drive unit 240 through the above steps, the gripping, moving, and releasing of the workpiece are achieved.

[0110] By adopting the transmission mechanism provided in this disclosure, compared with the separate rotary table 260 and intelligent gripper in related technologies, the compactness of the structural layout is improved and the space occupancy rate is reduced. Furthermore, the control logic of the transmission mechanism reduces the control difficulty compared with the separate control of the rotary table 260 and intelligent gripper in related technologies.

[0111] Optionally, there are multiple mounting holes 232, which are spaced apart and evenly distributed along the circumference of the second rotating body 230. There are also multiple transmission components, each corresponding to one of the multiple mounting holes 232.

[0112] In this embodiment, by providing multiple mounting holes 232 at circumferential intervals along the second rotating body 230 to correspond to multiple transmission components distributed along the circumference of the second rotating body 230, the synchronous movement of multiple transmission components to workpieces can be controlled simultaneously, which can adapt to the processing requirements of multiple processes and improve work efficiency.

[0113] Optionally, combined Figure 8 and Figure 9 As shown, the die-cutting system 1 also includes a loading mechanism 500. The loading mechanism 500 includes a loading vacuum chamber 522 and a loading gripper 524. The loading vacuum chamber 522 is connected to the loading port 114. The loading gripper 524 is disposed inside the loading vacuum chamber 522 and is used to move the workpiece to be processed in the loading vacuum chamber 522 into the vacuum processing chamber 120 through the loading port 114. The unloading mechanism 600 includes an unloading vacuum chamber 622 and an unloading gripper 624. The unloading vacuum chamber 622 is connected to the unloading port 115. The unloading gripper 624 is disposed inside the unloading vacuum chamber 622 and is used to move the processed workpiece in the vacuum processing chamber 120 into the unloading vacuum chamber 622 through the unloading port 115.

[0114] In this embodiment, the loading mechanism 500 includes a loading vacuum chamber 522 and a loading gripper 524. The unloading mechanism 600 includes an unloading vacuum chamber 622 and an unloading gripper 624. The loading vacuum chamber 522 and the unloading vacuum chamber 622 are respectively connected to the vacuum processing chamber 120 through a loading port 114 and a unloading port 115. The loading gripper 524 and the unloading gripper 624 are respectively disposed within the loading vacuum chamber 522 and the unloading vacuum chamber 622.

[0115] The die-cutting system 1 provided in this disclosure includes a vacuum die-cutting chamber 100 suitable for processing and producing mobile phone glass lenses. It also includes a loading vacuum chamber 522 and a unloading vacuum chamber 622, both of which are connected to a vacuum processing chamber 120. This ensures that the optical glass is in a vacuum environment during processing and during loading and unloading, thereby meeting the required vacuum environment for processing and improving the processing effect of the optical glass. Furthermore, by placing the loading gripper 524 and the unloading gripper 624 within the loading vacuum chamber 522 and the unloading vacuum chamber 622 respectively, a vacuum environment is maintained during both loading and unloading processes, further meeting the production environment requirements for optical glass and improving the processing effect.

[0116] Optionally, combined Figure 9 , Figure 13 and Figure 14 As shown, the feeding mechanism 500 also includes a feeding vacuum treatment component 520, a feed valve 540, and a feeding valve 530. The feeding vacuum treatment component 520 is configured with a feeding vacuum chamber 522, a feed port 526, and a feeding end, which is connected to the feed port 114. The feed valve 540 is located at the feed port 526 and is used to open or close the feed port 526. The feeding valve 530 is located at the feeding end and is used to open or close the feeding port 114.

[0117] In this embodiment, the loading mechanism 500 is equipped with a loading vacuum treatment component 520. The loading vacuum treatment component 520 cooperates with the vacuum processing chamber 120 of the vacuum molding chamber 100. The loading vacuum treatment component 520 provides a vacuum transfer space for the workpiece that is about to enter the vacuum processing chamber 120, thereby meeting the vacuum environment requirements of optical glass and improving the stability of system operation.

[0118] Furthermore, combined Figure 13 As shown, the loading vacuum treatment unit 520 includes a loading vacuum chamber 522, a feed inlet 526, and a loading end. The loading end is connected to the feed inlet 114, and a loading valve 530 is disposed at the loading end. A feed valve 540 is disposed at the feed inlet 526. A loading gripper 524 is disposed inside the loading vacuum chamber 522.

[0119] The loading process is as follows: The feed valve 540 is opened, and the workpiece to be processed is fed into the loading vacuum chamber 522 through the feed port 526. The feed valve 540 is then closed. The loading vacuum chamber 522 is evacuated until its vacuum level matches that of the vacuum processing chamber 120, thereby improving the smoothness of the opening of the loading valve 530. The loading valve 530 is then opened, and the workpiece to be processed in the loading vacuum chamber 522 is moved into the vacuum processing chamber 120 using the loading gripper 524. The loading valve 530 is then closed, completing the loading operation.

[0120] Optionally, combined Figure 9 , Figure 13 and Figure 14 As shown, the feeding mechanism 500 also includes a feeding bracket 512 and a feeding gripping mechanism. A feeding vacuum treatment component 520 is disposed on the feeding bracket 512. The feeding bracket 512 includes a feeding tray 512 for storing workpieces to be processed. The feeding gripping mechanism is disposed on the feeding bracket 512 and is used to transfer the workpieces to be processed from the feeding tray 512 to the feeding vacuum chamber 522 through the feed inlet 526.

[0121] In this embodiment, the loading support 512 supports the loading vacuum processing component 520, the loading tray 512, and the loading gripping mechanism. The loading tray 512 stores the workpieces to be processed. Multiple workpieces are pre-stored on the loading tray 512 to improve the continuity of the loading process and thus increase production efficiency. The loading gripping mechanism moves the workpieces to be processed into the loading vacuum chamber 522. Through the loading tray 512, the loading gripping mechanism, and the loading processing component, the loading process is continuously connected to improve loading efficiency.

[0122] Optionally, combined Figure 9 , Figure 15 and Figure 16 As shown, the feeding mechanism 600 includes a feeding vacuum treatment component 620, a discharge valve 640, and a feeding valve 630. The feeding vacuum treatment component 620 is configured with a feeding vacuum chamber 622, a discharge port 626, and a feeding end, which is connected to the discharge port 115. The discharge valve 640 is located at the discharge port 626 and is used to open or close the discharge port 626. The feeding valve 630 is located at the feeding end and is used to open or close the feeding port 115.

[0123] In this embodiment, the unloading vacuum processing component 620 includes an unloading vacuum chamber 622, an outlet 626, and an unloading end. The unloading end is equipped with a unloading valve 630. The outlet 626 is equipped with an outlet valve 640. An unloading gripper 624 is disposed in the unloading vacuum chamber 622.

[0124] The unloading process includes: maintaining the vacuum level of the unloading vacuum chamber 622 consistent with that of the vacuum processing chamber 120 to improve the smoothness of the unloading valve 630 opening. After the vacuum levels are consistent, the unloading valve 630 is opened, and the unloading gripper 624 extends into the vacuum processing chamber 120 to remove the processed workpiece. After removal, the unloading valve 630 is closed. The vacuum in the unloading vacuum chamber 622 is then broken. The discharge valve 640 is then opened to remove the processed workpiece from the unloading vacuum chamber 622.

[0125] By setting up a vacuum processing component 620, a feeding valve 630, and a discharge valve 640, vacuum communication with the vacuum processing chamber 120 is achieved, thereby improving the processing effect on optical glass.

[0126] Optionally, the unloading mechanism 600 further includes an unloading bracket 610 and an unloading gripping mechanism. The unloading vacuum-treated component 620 is disposed on the unloading bracket 610. The unloading bracket 610 includes an unloading tray 612 for storing the treated workpiece. The unloading gripping mechanism is disposed on the unloading bracket 610. The unloading gripping mechanism is used to remove the treated workpiece from the unloading vacuum chamber 622 through the discharge port 626 to the unloading tray 612.

[0127] In this embodiment, the unloading support 610 supports the unloading vacuum processing component 620 and the unloading gripping mechanism. The unloading support 610 also includes an unloading tray 612. The unloading tray 612 stores processed workpieces. The unloading gripping mechanism moves the processed workpieces from the unloading vacuum chamber 622 to the unloading tray 612. The unloading tray 612 can hold multiple processed workpieces. Through the unloading tray 612, the unloading gripping mechanism, and the unloading processing component, a continuous unloading process is achieved, thereby improving unloading efficiency.

[0128] Optionally, combined Figure 13 and Figure 14 As shown, the loading and gripping mechanism also includes a loading transfer table 560, a loading transfer gripper 570, and a loading gripper 550. The loading gripper 550 is used to move the workpiece to be processed from the loading tray 512 to the loading platform. The loading transfer gripper 570 is used to transfer the workpiece to be processed from the loading platform to the loading vacuum chamber 522. The loading transfer gripper 570 is mounted on the loading support 512 and can slide relative to the loading support 512 to move towards or away from the inlet 526 of the loading vacuum chamber 522. The linear sliding of the loading transfer gripper 570 relative to the loading support 512 facilitates loading with the inlet 526 and avoids interference with the loading vacuum chamber 520.

[0129] Optionally, combined Figure 15 and Figure 16 As shown, the unloading gripping mechanism also includes an unloading transfer table 660, an unloading transfer gripper 670, and an unloading gripper 650. The unloading transfer gripper 670 is used to transfer the processed workpiece in the unloading vacuum chamber 622 to the unloading loading table. The unloading gripper 650 is used to move the processed workpiece on the unloading loading table to the unloading tray 612. The unloading transfer gripper 670 is mounted on the unloading support 610 and can slide relative to the unloading support 610 to move towards or away from the discharge port 626 of the unloading vacuum chamber 622. The linear sliding of the unloading transfer gripper 670 relative to the unloading support 610 facilitates the unloading action with the discharge port 626 and avoids interference with the unloading vacuum processing unit 620.

[0130] Optionally, the die-cutting system 1 further includes: a first image acquisition system disposed on the loading mechanism 500, used to acquire first data of the workpiece to be processed on the loading mechanism 500; and a second image acquisition system disposed on the unloading mechanism 600, used to acquire second data of the processed workpiece on the unloading mechanism 600.

[0131] In this embodiment, the first image acquisition system is used to acquire image information of the loading pallet 512. Based on the acquired image information, the number of workpieces on the loading pallet 512 is determined for issuing a replenishment reminder. The second image acquisition system is used to acquire image information of the unloading pallet 612. Based on the acquired image information, the number of workpieces on the unloading pallet 612 is determined for issuing a pallet replacement prompt.

[0132] Optionally, the die-cutting system 1 further includes a control system, which includes a processor and a memory storing program instructions. The processor is configured to execute the control method of the die-cutting system 1 when executing the program instructions.

[0133] The steps of controlling the operation of the die-cutting system 1 by the control system include:

[0134] In response to the loading command from the loading mechanism 500, the loading gripper 550 is controlled to grab the workpiece and transfer it to the loading transfer table 560. The nitrogen valve of the loading vacuum chamber 522 is opened to fill the chamber with nitrogen. When the nitrogen pressure is equal to the external atmospheric pressure, the nitrogen valve is closed. The feed valve 540 is opened, and the loading transfer gripper 570 picks up the workpiece from the loading transfer table 560 and sends it into the loading vacuum chamber 522. Afterwards, the loading transfer gripper 570 is controlled to retract, and the feed valve 540 is closed. The loading vacuum chamber 522 is then evacuated. When the predetermined vacuum level is reached, the vacuum pump maintains the current vacuum level, waiting to send the workpiece from the loading vacuum chamber 522 into the vacuum molding chamber 100.

[0135] In response to the loading command from the vacuum molding chamber 100, it is determined whether the vacuum level of the vacuum processing chamber 120 is the same as that of the loading vacuum chamber 522 and the unloading vacuum chamber 622. If they are different, the vacuum processing chamber 120 is evacuated until the vacuum levels are the same, and the unloading valve 630 and the loading valve 530 are opened simultaneously. The lifting platform 330 of the lifting mechanism 300 is lowered to the loading / unloading position, and the loading gripper 524 in the loading vacuum chamber 522 and the unloading gripper 624 in the unloading vacuum chamber 622 simultaneously enter the vacuum processing chamber 120 to complete the feeding and unloading actions, respectively. After completion, the loading gripper 524 and the unloading gripper 624 are simultaneously retracted into the loading vacuum chamber 522 and the unloading vacuum chamber 622, respectively. The unloading valve 630 and the loading valve 530 are closed simultaneously, and the lifting platform 330 of the lifting mechanism 300 is raised to the working position.

[0136] When the lifting platform 330 rises to the working position, the conveying mechanism 200 moves, causing multiple sets of synchronously moving conveying components 250 to clamp simultaneously. The workpiece located at the loading station 310 is clamped by the conveying components 250. The first rotating body 210 and the second rotating body 230 rotate 60° relative to the rotary table 260, causing the multiple sets of conveying components 250 to rotate simultaneously, thereby realizing the rotational transfer of the mold between various stations. After the transfer is completed, the second rotating body 230 moves in the opposite direction, and the multiple sets of conveying components 250 are released simultaneously, and the workpiece is placed on the processing table of each station.

[0137] When the workpiece is conveyed from the loading station 310 to the preheating station via a rotary conveyor, the servo loading system 400 of the preheating station drives the upper module with the resistance heating element to press down and contact the workpiece, and then the upper and lower modules begin heating. When the workpiece temperature reaches the preheating temperature, the servo loading system 400 of the preheating station drives the upper module of the resistance heating module to move upward and detach from the workpiece. The conveying mechanism 200 moves to transfer the workpiece to the next station, namely the die-cutting station 134, thus completing the die preheating process.

[0138] After the workpiece arrives at the die-cutting station 134, the servo loading system 400 of the die-cutting station 134 drives the upper module of the resistance heating element to press down and contact the workpiece. Then, the upper and lower modules begin heating. When the workpiece temperature reaches the die-cutting temperature, the servo loading system 400 continues to load until the set pressure and displacement are reached, and maintains this position for a period of time. Then, the servo loading system 400 of the die-cutting station 134 drives the upper module of the resistance heating element to move upward and detach from the workpiece. The conveying mechanism 200 transfers the workpiece to the next station, the pressure-holding station, thus completing the initial die-cutting process.

[0139] After the workpiece reaches the pressure holding station, the servo loading system 400 of the pressure holding station drives the upper module of the resistance heating element to press down and contact the workpiece. Then the mold begins to cool down, while the servo loading system 400 continues to load until the set pressure holding pressure and displacement are reached. When the workpiece temperature reaches the pressure holding temperature and is maintained for a period of time, the servo loading system 400 of the pressure holding station drives the upper module of the resistance heating element to move upward and detach from the workpiece. The conveying mechanism 200 transfers the workpiece to the next station, the cooling station 138, thus completing the two-stage pressure holding process.

[0140] After the workpiece arrives at the cooling station 138, the servo loading system 400 of the cooling station 138 drives the upper module of the water cooling module to press down and contact the workpiece. Then, the upper and lower modules start circulating water cooling for temperature reduction. When the workpiece temperature reaches the discharge temperature, the servo loading system 400 of the cooling station 138 drives the upper module of the water cooling module to move upward and detach from the workpiece. The conveying mechanism 200 transfers the workpiece to the next station, namely the unloading station 320 of the lifting platform 330, thus completing the mold cooling process.

[0141] After the workpiece completes all molding processes and returns to the unloading position 320 of the lifting platform 330, the loading valve 530 and unloading valve 630 are simultaneously opened, and the lifting platform 330 descends to the loading / unloading position. The loading gripper 524 in the loading vacuum chamber 522 and the unloading gripper 624 in the unloading vacuum chamber 622 simultaneously enter the vacuum processing chamber 120 to complete the feeding and unloading actions respectively. After completion, the loading gripper 524 and the unloading gripper 624 simultaneously retract into the loading vacuum chamber 522 and the unloading vacuum chamber 622 respectively. Simultaneously, the unloading valve 630 and the loading valve 530 are closed, and the lifting platform 330 of the lifting mechanism 300 rises to the working position. The next cycle continues.

[0142] In response to the discharge command, the nitrogen valve of the discharge vacuum chamber 622 is opened, filling the chamber with nitrogen. When the nitrogen pressure is the same as the external atmospheric pressure, the nitrogen valve is closed. The discharge valve 640 is opened, and the discharge transfer gripper 670 picks up the workpiece from the discharge vacuum chamber 622 and sends it to the discharge transfer table 660. Then, the discharge transfer gripper 670 is retracted and the discharge valve 640 is closed. The discharge vacuum chamber 622 is evacuated. When the predetermined vacuum level is reached, the vacuum pump maintains the current vacuum level, waiting to transfer and remove the workpiece from the discharge station 320 in the vacuum molding chamber 100.

[0143] After the workpiece arrives at the unloading transfer table 660, the unloading gripper 650 is controlled to transfer the workpiece from the transfer table to the unloading pallet 612. The second image acquisition system acquires images of the unloading pallet 612. When the acquired image information determines that there is no empty space on the unloading pallet 612, a reminder message is issued to the worker to replace the pallet or unload the workpiece.

[0144] By employing the engraving system 1 provided in this disclosure, a multi-station rotary arrangement processing technology can be used to achieve multi-station molding in a vacuum environment. Furthermore, by adopting a three-chamber vacuum replacement method, the vacuum processing chamber 120 can be kept in a vacuum state, improving the operational stability of the vacuum engraving chamber 100 and reducing nitrogen consumption. By setting up an automatic feeding mechanism 500 and an unloading mechanism 600, the rate of intelligent and unmanned operation is improved.

[0145] In some embodiments, combined with Figures 1 to 16 The die-cutting system shown provides a control method for the die-cutting system, combined with Figure 17 As shown, the control methods include:

[0146] S1702, in response to the operating command, controls the opening of the vacuum molding chamber.

[0147] S1704 After the workpiece to be processed is placed into the vacuum processing chamber, the vacuum die-cutting chamber is closed and the conveying mechanism is operated to move the workpiece to be processed sequentially between multiple processing stations along the circumference of the vacuum processing chamber.

[0148] S1706: When the workpiece to be processed moves to each processing station, the servo loading system corresponding to the processing station is controlled to run in order to process the workpiece to be processed.

[0149] The control method for the engraving system provided in this disclosure is applied to the engraving system of any of the above embodiments. The control method includes: receiving a running command; responding to the running command by controlling the vacuum engraving chamber to open for placing the workpiece to be processed; after the workpiece is placed in the vacuum processing chamber, controlling the vacuum engraving chamber to close so that the optical glass processing is conducted in a vacuum environment; controlling the operation of a conveying mechanism to sequentially drive the workpiece to be processed through multiple processing stations distributed circumferentially to complete the corresponding processing steps. Specifically, when the conveying mechanism moves the workpiece to each processing station, the servo loading system of the corresponding station is controlled to operate to process the workpiece. After completing the corresponding processing, the conveying mechanism is controlled to continue rotating the workpiece to the next station, rotating sequentially; one rotation completes the processing of the workpiece—optical glass.

[0150] By employing the control method of the engraving system provided in this disclosure, and by controlling the conveying mechanism and servo loading system, multiple processing stations arranged circumferentially along the vacuum engraving chamber are used to complete a multi-station rotary processing procedure for optical glass. Through the cooperation of the conveying mechanism with multiple processing stations and multiple servo loading systems, the workpiece is sequentially rotated among multiple processing stations to complete the corresponding processing steps, improving processing efficiency, meeting the requirements of the vacuum processing environment, and enhancing the processing effect on optical glass.

[0151] Optionally, the conveying mechanism further includes: a first driving member, the output end of which is connected to the first rotating body for driving the first rotating body to rotate; and a second driving member, the output end of which is connected to the second rotating body for driving the second rotating body to rotate. The steps for controlling the operation of the conveying mechanism include:

[0152] Control the second drive component to rotate in the first direction to drive the conveyor component to move from the first end of the mounting hole to the second end, so as to clamp a workpiece to be processed on a processing station;

[0153] After controlling the first and second driving components to rotate synchronously by a preset angle, the workpiece to be processed is moved to the next adjacent processing station.

[0154] Control the second driving component to rotate in the second direction, so as to drive the transmission component to move from the second end of the mounting hole to the first end, so as to release the workpiece to be processed;

[0155] The first direction and the second direction are opposite, and the distance from the first end to the center of rotation of the second rotating body is greater than the distance from the second end to the center of rotation of the second rotating body.

[0156] In this embodiment, the operation of the first and second driving members is controlled to drive the first and second rotating bodies to rotate. Specifically, in response to the operation command, the second driving member is first controlled to drive the second rotating body to rotate along a first direction, so that the mounting hole in the second rotating body rotates, thereby causing the movable part of the conveyor to move relative to the mounting hole, moving from the first end of the mounting hole to the second end, driving the guide rod of the conveyor to move towards the center of the second rotating body, thereby driving the clamping part of the conveyor to clamp the workpiece. After the workpiece is clamped, the first and second driving members are controlled to rotate synchronously by a preset angle to the next station. After moving to the next station, the second driving member is controlled to drive the second rotating body to rotate along a second direction, so that the mounting hole rotates, thereby causing the movable part located in the mounting hole to move from the second end of the mounting hole to the first end. Since the second end of the mounting hole is closer to the edge of the second rotating body relative to the first end, the guide rod moves towards the side away from the center of the second rotating body, thereby causing the first and second clamping bodies of the clamping part to separate, completing the release of the workpiece. By repeatedly controlling the first and second driving components according to the above steps, the workpiece to be processed passes through multiple processing stations in sequence, thereby realizing the clamping, moving and releasing of the workpiece.

[0157] Optionally, the die-cutting system also includes a lifting mechanism, and after responding to the step of the operation command, it further includes: acquiring workpiece information on the loading station and / or unloading station; and controlling the lifting mechanism to rise or fall according to the workpiece information, so as to drive the loading station and unloading station to reciprocate between the working position and the loading / unloading position.

[0158] In this embodiment, by acquiring workpiece information at the loading and / or unloading stations, it is determined whether loading / unloading operations are required. If loading / unloading operations are required, the lifting mechanism is controlled to descend to the loading / unloading position, and a running command is sent to control the vacuum molding chamber to open for loading / unloading. After the loading / unloading operations are completed, the lifting mechanism is controlled to rise to the working position, allowing the conveying mechanism to perform circumferential processing on the workpiece to be processed. By controlling the lifting mechanism to drive the loading and unloading stations to reciprocate between the working position and the loading / unloading position, the efficiency of loading / unloading is improved. Through the coordinated operation of the lifting mechanism, the conveying mechanism, and multiple processing stations, continuous processing of the workpiece is achieved, improving the continuity of the processing steps and enabling continuous processing of multiple processing steps, thereby improving the production efficiency of optical glass.

[0159] Optionally, infrared sensors are installed at positions corresponding to the loading and unloading stations to detect the presence of workpieces at either station. If a workpiece is present at the unloading station but not at the loading station, the lifting mechanism is lowered to the loading / unloading position for loading and unloading. After completion, it rises back to the working position and rotates circumferentially via the conveying mechanism, enabling continuous processing and improving efficiency.

[0160] Optionally, after controlling the lowering of the lifting mechanism based on the workpiece information, the method further includes: in response to the loading / unloading request, obtaining the vacuum level of the processing chamber of the vacuum processing chamber.

[0161] Adjust the vacuum levels of the loading and unloading chambers of the loading and unloading vacuum chambers respectively, based on the vacuum level of the processing chamber.

[0162] When the vacuum levels of the loading chamber and unloading chamber are the same as those of the processing chamber, the operation of the loading mechanism and the operation of the unloading mechanism are controlled respectively.

[0163] In this embodiment, a loading / unloading request command is received. In response to the loading / unloading request, the vacuum levels of the processing chamber, the loading chamber, and the unloading chamber are acquired. Based on the processing chamber vacuum level, the loading and unloading chamber vacuum levels are adjusted to match the processing chamber vacuum level. By maintaining consistent vacuum levels in all three chambers, the loading and unloading mechanisms are further controlled to complete the loading / unloading operation.

[0164] The control method provided in this disclosure can ensure that the vacuum degree of the vacuum processing chamber, the loading vacuum chamber and the unloading vacuum chamber are kept consistent, avoid the difference in vacuum degree between the chambers, and improve the stability of the operation of the loading mechanism and the unloading mechanism.

[0165] Optionally, the feeding mechanism also includes a feeding valve. The steps for controlling the operation of the feeding mechanism include: controlling the feeding valve to open and controlling the feeding gripper to move the workpiece to be processed in the feeding vacuum chamber into the vacuum processing chamber. After the workpiece is moved in, the feeding valve is controlled to close.

[0166] In this embodiment, the steps for controlling the operation of the loading mechanism include: controlling the loading valve to open, thereby connecting the loading vacuum chamber and the vacuum processing chamber; then controlling the loading gripper to extend into the vacuum processing chamber and send the workpiece to be processed from the loading vacuum chamber into the vacuum processing chamber; after placement, the loading gripper retracts into the loading vacuum chamber; and finally, controlling the loading valve to close, completing the loading action.

[0167] Optionally, the unloading mechanism also includes an unloading valve. The steps for controlling the operation of the unloading mechanism include: controlling the unloading valve to open and controlling the unloading gripper to move the processed workpiece from the vacuum processing chamber into the unloading vacuum chamber. After the workpiece is moved out, the unloading valve is controlled to close.

[0168] In this embodiment, the vacuum level of the unloading vacuum chamber is controlled to be consistent with that of the vacuum processing chamber to improve the smoothness of the unloading valve opening. After the vacuum levels are consistent, the steps for controlling the operation of the unloading mechanism include: controlling the unloading valve to open so that the unloading vacuum chamber is connected to the vacuum processing chamber; then controlling the unloading gripper to extend into the vacuum processing chamber to remove the processed workpiece; after removal, the unloading valve closes, completing the unloading action.

[0169] Optionally, the unloading mechanism also includes a discharge valve and an unloading gripping mechanism. After the discharge valve is closed, the mechanism further includes: depressurizing the unloading vacuum chamber. After depressurization, the discharge valve is opened, and the unloading gripping mechanism is used to remove the processed workpiece from the unloading vacuum chamber through the discharge port to the unloading tray. After removal, the discharge valve is closed, and the unloading vacuum chamber is evacuated.

[0170] In this embodiment, after the processed workpiece is removed from the vacuum processing chamber to the unloading vacuum chamber, the unloading step further includes: depressurizing the unloading vacuum chamber to improve the smoothness of the discharge valve opening. After depressurization, the discharge valve is opened, and the processed workpiece in the unloading vacuum chamber is removed through the discharge port to the unloading tray using the unloading gripping mechanism. After removal, the discharge valve is closed, and the unloading vacuum chamber is evacuated to provide a vacuum environment for the next unloading operation, thereby improving the continuity of the unloading process.

[0171] Optionally, the feeding mechanism further includes a feed valve and a feeding gripping mechanism. Before the step of obtaining the vacuum level of the processing chamber of the vacuum processing chamber, the mechanism further includes: controlling the depressurization of the feeding vacuum chamber and controlling the opening of the feed valve; controlling the feeding gripping mechanism to grip the workpiece to be processed and feeding it into the feeding vacuum chamber; after feeding, controlling the feed valve to close and evacuating the feeding vacuum chamber.

[0172] In this embodiment, before loading the vacuum processing chamber, the loading gripper mechanism is controlled to load the vacuum-processed workpiece. Specifically, this includes: first, depressurizing the loading vacuum chamber to improve the smoothness of the feed valve opening; after depressurization, opening the feed valve and controlling the loading gripper mechanism to feed the workpiece into the loading vacuum chamber through the feed port, then closing the feed valve; next, evacuating the loading vacuum chamber until the vacuum level matches that of the vacuum processing chamber, thus meeting the operating environment requirements for loading into the vacuum processing chamber and improving the smoothness of the processing.

[0173] Optionally, before controlling the feeding and gripping mechanism to feed the vacuum-processed parts, the method further includes: acquiring first data of the workpieces to be processed in the feeding tray of the feeding mechanism. If the first data is greater than a first quantity threshold, the feeding and gripping mechanism is controlled to perform a gripping operation. If the first data is less than or equal to the first quantity threshold, a replenishment reminder is issued. That is, the number of workpieces to be processed on the feeding tray is low and needs to be replenished in a timely manner. By issuing reminder information, the staff can be promptly alerted, thereby improving the continuity and stability of the entire equipment processing process.

[0174] Optionally, first data within the loading tray is acquired via a first image acquisition system. The first data includes the number of workpieces to be processed. The first quantity threshold can be reasonably set based on the capacity of the loading tray, and is not specifically limited here.

[0175] Optionally, after controlling the discharge valve to close following the step of removing the processed workpiece from the unloading vacuum chamber, the control method further includes: acquiring second data on the unloading tray. If the second data is greater than or equal to a second quantity threshold, an unloading reminder is issued. This promptly reminds the worker to replace the unloading tray with a new one for storing the processed workpiece. If the second data is less than the second quantity threshold, the unloading gripping mechanism is controlled to perform the unloading operation.

[0176] In some embodiments, combined with Figures 1 to 16 The die-cutting system shown, combined with Figure 18 As shown, the control method for the die-cutting system includes:

[0177] S1801, in response to the system startup request, controls the depressurization of the loading vacuum chamber and the unloading vacuum chamber respectively;

[0178] S1802, after depressurization, the feed valve for the vacuum treatment component is opened; and

[0179] S1803, controls the opening of the discharge valve for vacuum-processed components;

[0180] S1804, controls the feeding gripping mechanism to grip the workpiece to be processed and send it into the feeding vacuum chamber;

[0181] S1805, after being fed in, controls the feed valve to close and evacuates the feeding vacuum chamber.

[0182] S1806, controls the unloading gripping mechanism to move the processed workpiece in the unloading vacuum chamber through the discharge port to the unloading tray;

[0183] S1807, after removal, controls the discharge valve to close and evacuates the discharge vacuum chamber.

[0184] S1808, Obtain workpiece information at the loading station and / or unloading station;

[0185] S1809: When there is a workpiece at the unloading station and no workpiece at the loading station, control the lifting mechanism to descend to the loading / unloading position.

[0186] S1810, obtain the vacuum level of the machining cavity; and

[0187] S1811, respectively obtain the vacuum degree of the loading chamber of the loading vacuum chamber and the vacuum degree of the unloading vacuum chamber;

[0188] S1812, Based on the vacuum degree of the processing chamber, adjust the vacuum degree of the loading chamber of the loading vacuum chamber and the vacuum degree of the unloading vacuum chamber respectively, so that the vacuum degree of the loading chamber and the vacuum degree of the unloading chamber are the same as the vacuum degree of the processing chamber.

[0189] S1813, control the opening of the loading valve and control the loading gripper to move the workpiece to be processed in the loading vacuum chamber into the vacuum processing chamber; after moving in, control the closing of the loading valve.

[0190] S1814 controls the opening of the unloading valve and controls the unloading gripper to move the processed workpiece from the vacuum processing chamber into the unloading vacuum chamber; after the workpiece is moved out, controls the unloading valve to close.

[0191] S1815 controls the lifting mechanism to rise, thereby moving the loading and unloading stations to their working positions.

[0192] S1816, control the second drive member to rotate along the first direction to drive the conveyor to move from the first end of the mounting hole to the second end, so as to clamp the workpiece to be processed on a processing station.

[0193] S1817, after controlling the first and second driving components to rotate synchronously by a preset angle, the workpiece to be processed is moved to the next adjacent processing station.

[0194] S1818, control the second drive member to rotate in the second direction to drive the conveyor member to move from the second end of the mounting hole to the first end to release the workpiece to be processed.

[0195] By repeatedly controlling the first and second drive components according to the above steps, the workpiece to be processed is sequentially passed through multiple processing stations to the unloading station.

[0196] The specific steps for controlling and processing the workpiece by operating the servo loading system corresponding to the control and processing station include:

[0197] When the workpiece is conveyed from the loading station to the preheating station via a rotary conveyor, the servo loading system controlling the preheating station drives the upper module with the resistance heating element to press down and contact the workpiece, and then the upper and lower modules begin heating. When the workpiece temperature reaches the preheating temperature, the servo loading system controlling the preheating station drives the upper module to move upward and detach from the workpiece. The conveyor mechanism then moves the workpiece to the next station, the die-cutting station, thus completing the die preheating process.

[0198] After the workpiece arrives at the die-cutting station, the servo loading system controlling the die-cutting station drives the upper module with the resistance heating element to press down into contact with the workpiece, and then the upper and lower modules begin heating. When the workpiece temperature reaches the die-cutting temperature, the servo loading system continues to load until the set pressure and displacement are reached, and maintains this position for a period of time. The servo loading system controlling the die-cutting station then drives the upper module upward, detaching it from the workpiece. The conveying mechanism transfers the workpiece to the next station, the pressure-holding station, thus completing the initial die-cutting process.

[0199] After the workpiece reaches the pressure holding station, the servo loading system controlling the pressure holding station drives the upper module to press down and contact the workpiece. Then, the mold begins to cool down, while the servo loading system continues to load until the set pressure holding pressure and displacement are reached. When the workpiece temperature reaches the pressure holding temperature and is maintained for a period of time, the servo loading system controlling the pressure holding station drives the upper module to move upward and detach from the workpiece. The conveying mechanism transfers the workpiece to the next station, the cooling station, thus completing the two-stage pressure holding process.

[0200] After the workpiece arrives at the cooling station, the servo loading system controlling the cooling station drives the upper module of the water cooling module to press down and contact the workpiece. Then, the upper and lower modules start circulating water cooling for temperature reduction. When the workpiece temperature reaches the discharge temperature, the servo loading system controlling the cooling station drives the upper module of the water cooling module to move upward and detach from the workpiece. The conveying mechanism transfers the workpiece to the next station, which is the unloading station of the lifting mechanism, thus completing the mold cooling process.

[0201] After the workpiece completes all molding processes, it returns to the unloading station of the lifting mechanism.

[0202] By employing the control method of the die-cutting system provided in this disclosure, optical glass can be processed using a multi-station rotary arrangement process, thereby improving production efficiency. Furthermore, it enables processing of optical glass in a vacuum environment, improving processing results and achieving intelligent control, thus reducing manpower requirements.
