[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0055] In some embodiments, combined Figures 1 to 7 As shown, a conveying mechanism 200 is provided, comprising: a first rotating body 210, a second rotating body 230 and a conveying member 250. The first rotating body 210 is capable of rotating, and the first rotating body 210 includes a through hole. The second rotating body 230 is mounted in the through hole, and the second rotating body 230 is capable of rotating relative to the first rotating body 210, and the second rotating body 230 includes a mounting hole 232, and the mounting hole 232 is located on the circumference of the through hole. The conveying member 250 is mounted on the first rotating body 210, and the conveying member 250 includes a movable portion 251, which is arranged in the mounting hole 232 and can move along the mounting hole 232. In the process of relative rotation between the first rotating body 210 and the second rotating body 230, the movable portion 251 can move along the mounting hole 232.

[0056] The present disclosure provides a conveying mechanism 200 including a first rotating body 210, a second rotating body 230 and a conveying member 250. The second rotating body 230 is installed on the first rotating body 210, and the second rotating body 230 can rotate 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 portion 251 and a clamping portion 252 connected to each other. The movable portion 251 is arranged in the mounting hole 232 and can move along the mounting hole 232. Moreover, in the process of the movable portion 251 moving along the mounting hole 232, the clamping portion 252 is driven to move, so as to achieve the function of grabbing the workpiece.

[0057] By adopting the conveying mechanism 200 provided in the present 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 conveying member 250 moves along the mounting hole 232, thereby driving the clamping part 252 connected to the movable part 251 to move, thereby achieving the grasping of the workpiece.

[0058] The conveying mechanism 200 provided by the present disclosure has both rotation and gripping functions. By integrating the gripping and rotation functions into one, it reduces space usage and improves space utilization. Compared to the related art that uses independent mechanisms, it also simplifies the control system and avoids the need to connect two independent systems.

[0059] In some embodiments, combined 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 portion 251 from the first end to the second end of the mounting hole 232 gradually increases.

[0060] In this embodiment, the mounting hole 232 includes a first end and a second end. The movable portion 251 can move from the first end of the mounting hole 232 to the second end, or from the second end of the mounting hole 232 to the first end. The distance from the first end to the center of rotation of the second rotating body 230 is not equal to the distance from the second end to the center of rotation of the second rotating body 230. In this embodiment, the distance between the moving trajectory of the movable portion 251 from the first end to the second end of the mounting hole 232 and the center of rotation of the second rotating body 230 gradually increases. In this way, the line connecting the first end and the second end is tilted relative to the circumference of the second rotating body 230, and then during the movement of the movable portion 251 along the mounting hole 232, the movable portion 251 is displaced along the radial direction of the second rotating body 230, and can drive the clamping portion 252 to move to achieve grasping.

[0061] In some embodiments, combined 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 portion 251 from the first end to the second end of the mounting hole 232 gradually becomes smaller.

[0062] In this embodiment, the mounting hole 232 includes a first end and a second end. The movable portion 251 can move from the first end of the mounting hole 232 to the second end, or from the second end of the mounting hole 232 to the first end. The distance from the first end to the center of rotation of the second rotating body 230 is not equal to the distance from the second end to the center of rotation of the second rotating body 230. In this embodiment, the distance between the moving trajectory of the movable portion 251 from the first end to the second end of the mounting hole 232 and the center of rotation of the second rotating body 230 gradually decreases. In this way, the line connecting the first end and the second end is tilted relative to the circumference of the second rotating body 230, and then during the movement of the movable portion 251 along the mounting hole 232, the movable portion 251 is displaced along the radial direction of the second rotating body 230, and can drive the clamping portion 252 to move to achieve grasping.

[0063] Optionally, combined Figures 1 to 3 As shown, the mounting hole 232 is a strip-shaped hole, and the extending direction of the strip-shaped hole extends along the circumferential direction of the second rotating body 230 .

[0064] In this embodiment, the mounting hole 232 is configured as a strip-shaped hole to provide space for movement of the movable portion 251. The strip-shaped hole extends along the circumference of 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 portion 251 to drive the gripping portion 252 to move.

[0065] Optionally, the mounting hole 232 includes a straight bar hole, an arc-shaped bar hole or a broken line bar hole, so that the movable part 251 can 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 is not equal.

[0066] Optionally, combined Figure 1 and Figure 2 As shown, the gripping portion 252 includes a guide member 253 disposed on the first rotating body 210. The guide member 253 is slidable relative to the first rotating body 210 and is connected to the movable portion 251. A gripping member 254 is slidably connected to the guide member 253. As the movable portion 251 moves along the mounting hole 232, it causes the guide member 253 to slide relative to the first rotating body 210, thereby causing the gripping member 254 to move, thereby gripping or releasing a workpiece.

[0067] In this embodiment, the clamping portion 252 includes a guide member 253 and a clamping member 254. The guide member 253 is connected to the movable portion 251, and the clamping member 254 is slidably connected to the guide member 253. The guide member 253 is capable of sliding relative to the first rotating body 210. As the movable portion 251 moves along the mounting hole 232, it displaces radially along the second rotating body 230, thereby causing the guide member 253 to slide relative to the first rotating body 210. The sliding of the guide member 253 causes the clamping member 254 to slide relative to the guide member 253, thereby clamping or releasing the workpiece.

[0068] 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 arranged relative to each other and are 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. In the process of sliding relative to the first rotating body 210, the guide member 253 drives the first clamping body 2541 to slide along the first guide groove and drives the second clamping body 2542 to slide along the second guide groove 2535 to clamp or release the workpiece.

[0069] In this embodiment, the guide member 253 includes a first guide groove 2533 and a second guide groove 2535 that are arranged relative to each other at an angle. The clamping member 254 includes a first clamping body 2541 and a second clamping body 2542 that are arranged 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 the first sliding direction, the first clamping body 2541 and the second clamping body 2542 approach each other to achieve coordinated clamping of the workpiece. When the first clamping body 2541 and the second clamping body 2542 slide along the second sliding direction, the first clamping body 2541 and the second clamping body 2542 move away from each other to achieve release of the workpiece. The first sliding direction and the second sliding direction are in opposite directions.

[0070] Optionally, combined Figure 2 As shown, the conveying member 250 further includes a mounting seat 255 mounted on the first rotating body 210 , and the guide member 253 is mounted on the mounting seat 255 , and the guide member 253 can slide relative to the mounting seat 255 .

[0071] In this embodiment, the conveying member 250 also includes a mounting seat 255 provided on the first rotating body 210. The guide member 253 is mounted on the first rotating body 210 and is capable of sliding relative to the mounting seat 255. In this way, when the movable portion 251 moves along the mounting hole 232, it drives the guide member 253 to slide relative to the mounting seat 255, thereby driving the clamping member 254 to move for clamping or releasing the workpiece. By using the conveying member 250 provided by the present disclosure in conjunction with the second rotating body 230, a mechanical drive is achieved to clamp or release the workpiece, which reduces power consumption compared to the related art using a drive member such as a motor and a cylinder.

[0072] Optionally, combined Figure 2 As shown, the guide member 253 includes a guide rod 2531, which is mounted on the mounting seat 255 and can slide relative to the mounting seat 255. One end of the guide rod 2531 is connected to the movable portion 251. A guide block 2532 is mounted on the other end of the guide rod 2531. A first guide groove 2533 and a second guide groove 2535 are disposed in the guide block 2532 and are arranged obliquely relative to each other. A spring 2534 is mounted on the guide rod 2531 and is located between the movable portion 251 and the mounting seat 255.

[0073] In this embodiment, the guide member 253 includes a guide rod 2531, a guide block 2532, and a spring 2534. The mounting seat 255 includes a guide hole, through which the guide rod 2531 is inserted and slidably connected to the mounting seat 255. The two ends of the guide rod 2531 are respectively connected to the movable portion 251 and the guide block 2532. The spring 2534 is sleeved on the guide rod 2531 and located between the movable portion 251 and the mounting seat 255. A guide groove 2533 is provided in the guide block 2532. The movable portion 251 moves along the mounting hole 232, driving the guide rod 2531 to slide relative to the mounting seat 255. The guide rod 2531 drives the guide block 2532 to slide relative to the clamping portion 252 to clamp or release the workpiece. During the sliding movement of the guide rod 2531 relative to the mounting seat 255, the spring 2534 is compressed, and the spring 2534 causes the guide rod 2531 to reset. In this way, the coordinated operation of the conveying member 250 and the second rotating body 230 realizes the grasping or releasing of the workpiece, replaces the drive of the power member with the mechanical structure, reduces energy consumption, and realizes structural integration.

[0074] Optionally, the movable portion includes a pin, which is disposed in the mounting hole and one end of which is connected to the guide member 253 .

[0075] Optionally, combined Figure 1 As shown, the transmission mechanism 200 further includes a first driving member 220 and a second driving member 240. The output end of the first driving member 220 is connected to the first rotating body 210 for driving the first rotating body 210 to rotate. The output end of the second driving member 240 is connected to the second rotating body 230 for driving the second rotating body 230 to rotate.

[0076] In this embodiment, the conveying mechanism 200 further includes a first driving member 220 and a second driving member 240 for respectively driving the first rotating body 210 and the second rotating body 230. 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, thereby adjusting the position of the conveying member 250 and driving the conveying member 250 to clamp and release the workpiece.

[0077] 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 is configured to, in accordance with an operating instruction, control the second drive member 240 to rotate in a first direction to drive the conveying member 250 from the first end to the second end of the mounting hole 232. The controller then controls the first and second drive members 220, 240 to synchronously rotate by a preset angle, and then controls the second drive member 240 to rotate in a second direction to drive the conveying member 250 from the second end to the first end of the mounting hole 232. 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.

[0078] In this embodiment, the controller is used to control the operation of the first driving member 220 and the second driving 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 driving member 240 is first controlled to drive the second rotating body 230 to rotate in the first direction, so that the mounting hole 232 opened in the second rotating body 230 rotates, thereby causing the movable portion 251 to move relative to the mounting hole 232, so that the movable portion 251 moves from the first end of the mounting hole 232 to the second end, driving the guide rod 2531 to move toward the center of the second rotating body 230, and then driving the clamping portion 252 to clamp the workpiece. After the workpiece is clamped, the first driving member 220 and the second driving member 240 are controlled to rotate synchronously by a preset angle to the next workstation. After moving to the next workstation, the second driving member 240 is controlled to drive the second rotating body 230 to rotate in the second direction, thereby driving the mounting hole 232 to rotate, thereby causing the movable portion 251 located in the mounting hole 232 to move from the second end of the mounting hole 232 to the first end. Because the second end of the mounting hole 232 is closer to the edge of the second rotating body 230 than the first end, the guide rod 2531 moves toward the side away from the center of the second rotating body 230, thereby driving the first clamping body 2541 and the second clamping body 2542 of the clamping portion 252 to separate, completing the release of the workpiece. By repeatedly controlling the first driving member 220 and the second driving member 240 according to the above steps by the controller, the clamping, movement, and release of the workpiece are achieved.

[0079] By adopting the transmission mechanism provided by this disclosure, the compactness of the structural layout is improved and the space occupancy rate is reduced compared to the separate turntable 260 and intelligent gripper in the related art. In addition, the control logic of the transmission mechanism is simplified compared to the control logic of the related art that controls the turntable 260 and intelligent gripper separately.

[0080] Optionally, combined Figure 1 、 Figure 3 and Figure 5As shown, there are multiple mounting holes 232 , which are spaced and evenly distributed along the circumference of the second rotating body 230 . There are multiple transmission members 250 , which are arranged in a one-to-one correspondence with the multiple mounting holes 232 .

[0081] In this embodiment, a plurality of mounting holes 232 are arranged at intervals along the circumference of the second rotating body 230 to correspond to a plurality of conveying members 250 distributed along the circumferential side of the second rotating body 230, thereby achieving simultaneous control of the plurality of conveying members 250 for synchronous movement of workpieces, adapting to the processing requirements of multiple processes, and improving work efficiency.

[0082] Optionally, combined Figure 1 、 Figure 3 As shown, the conveying mechanism 200 further includes a turntable 260 and a plurality of processing tables. The turntable 260 includes a central hole, and the first rotating body 210 is mounted in the central hole. The first rotating body 210 is rotatable relative to the turntable 260. The plurality of processing tables are disposed on the turntable 260 and are spaced and evenly distributed along the circumference of the turntable 260. The number of the plurality of processing tables is the same as the number of the plurality of conveying members 250.

[0083] In this embodiment, a turntable 260 is provided to support the first rotating body 210 and the second rotating body 230. Furthermore, a plurality of processing tables are spaced apart along the circumference of the turntable 260.

[0107] Optical glass compression molding is an advanced processing technique that uses high-precision optical molds to form optical glass in a single press. This technique involves heating the optical glass to a specific temperature (typically between the transition temperature and the softening temperature) within the optical glass lens conveyor mechanism 2001. Pressure is then applied to the mold and the optical glass preform to induce plastic strain in the glass, replicating the mold's structure onto the surface of the optical glass.

Therefore, after the processing is complete, the resulting optical glass component requires no subsequent grinding or polishing and is ready for immediate use.

When the predetermined vacuum degree is reached, the vacuum pump maintains the current vacuum degree and waits for the workpiece in the loading vacuum chamber 522 to be sent into the vacuum engraving chamber 100.

[0144] In response to a loading instruction from the vacuum molding chamber 100, the vacuum processing chamber 120 is determined to be the same as the vacuum levels in the loading vacuum chamber 522 and the unloading vacuum chamber 622. If they are different, the vacuum processing chamber 120 is continuously evacuated until the vacuum levels are the same, and the unloading valve 630 and the loading valve 530 are simultaneously opened. The lifting platform 330 of the lifting mechanism 300 is controlled to descend to the loading and 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, completing the feeding and unloading operations, 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 controlled to close simultaneously, and the lifting platform 330 of the lifting mechanism 300 is controlled to ascend to the working position.

[0145] When the lift platform 330 rises to its working position, the transfer mechanism 200 moves, driving multiple sets of synchronously moving transfer members 250 to simultaneously clamp the workpiece on the loading station 310. The transfer members 250 then clamp the workpiece. The first and second rotating bodies 210 and 230 rotate 60° relative to the turntable 260, driving the multiple sets of transfer members 250 to rotate simultaneously, thereby achieving rotary transfer of the mold between the various stations. Once the mold is in place, the second rotating body 230 moves in the opposite direction, and the multiple sets of transfer members 250 are simultaneously released, allowing the workpiece to be placed on the processing table at each station.

[0146] When the workpiece is conveyed from the loading station 310 to the preheating station via rotary conveyor, the servo loading system 400 in the preheating station drives the upper die block with the resistance heating element downward to contact the workpiece, and then the upper and lower die blocks begin heating. When the workpiece reaches the preheating temperature, the servo loading system 400 in the preheating station drives the upper die block of the resistance heating module upward, away from the workpiece. The conveyor mechanism 200 then moves the workpiece to the next station, the engraving station 134, completing the mold preheating process.

[0147] After the workpiece arrives at the engraving station 134, the servo loading system 400 in this station drives the upper die of the resistance heater downward to contact the workpiece. The upper and lower die begin heating. When the workpiece reaches the molding temperature, the servo loading system 400 continues loading until the set pressure and displacement are achieved, which are maintained for a period of time. The servo loading system 400 in this station then drives the upper die of the resistance heater upward, clear of the workpiece. The conveyor mechanism 200 transfers the workpiece to the next station, the holding pressure station, completing the initial molding process.

[0148] After the workpiece reaches the holding station, the servo loading system 400 in this station drives the upper die of the resistance heating element downward to contact the workpiece. The mold then begins to cool, while the servo loading system 400 continues loading until the set holding pressure and displacement are achieved. Once the workpiece reaches the holding temperature and remains there for a period of time, the servo loading system 400 in this station drives the upper die of the resistance heating element upward, freeing it from the workpiece. The conveyor mechanism 200 transfers the workpiece to the next station, the cooling station 138, completing the second stage of the holding process.

[0149] After the workpiece reaches cooling station 138, the servo loading system 400 of cooling station 138 drives the upper die of the water-cooling module downward to contact the workpiece. The upper and lower die then begin circulating water cooling to reduce the temperature. When the workpiece reaches the exit temperature, the servo loading system 400 of cooling station 138 drives the upper die of the water-cooling module upward, freeing it from the workpiece. The conveyor mechanism 200 transfers the workpiece to the next station, unloading station 320 on the lifting platform 330, completing the mold cooling process.

[0150] After the workpiece completes all molding processes and returns to the unloading station 320 of the lifting platform 330, the loading valve 530 and the unloading valve 630 are opened at the same time, and the lifting platform 330 descends to the loading and unloading position. The loading gripper 524 in the loading vacuum chamber 522 and the unloading gripper 624 in the unloading vacuum chamber 622 enter the vacuum processing chamber 120 at the same time, completing the feeding and picking actions respectively. After completion, the loading gripper 524 and the unloading gripper 624 are retracted into the loading vacuum chamber 522 and the unloading vacuum chamber 622 respectively at the same time. And the unloading valve 630 and the loading valve 530 are controlled to close at the same time, and the lifting platform 330 of the lifting mechanism 300 is controlled to rise to the working position. Continue to the next cycle.

[0151] In response to the discharge instruction, the nitrogen valve of the unloading vacuum chamber 622 is opened, and nitrogen is filled into the unloading vacuum chamber 622. 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 unloading transfer gripper 670 clamps the workpiece in the unloading vacuum chamber 622 and sends it to the unloading transfer table 660. Afterwards, the unloading transfer gripper 670 is controlled to exit, and the discharge valve 640 is closed. The unloading vacuum chamber 622 is controlled to start vacuuming. When the predetermined vacuum degree is reached, the vacuum pump maintains the current vacuum degree and waits for the workpiece of the unloading station 320 in the vacuum molding chamber 100 to be transferred and taken out again.

[0152] After the workpiece arrives at the unloading turntable 660, the unloading gripper 650 is controlled to move the workpiece from the turntable to the unloading tray 612. The second image acquisition system captures images of the unloading tray 612. If the captured image information determines that there is no empty space on the unloading tray 612, a reminder message is issued to the staff to change the tray or unload the workpiece.

[0153] By adopting the molding device 1 provided by the present disclosure and employing a multi-station rotary arrangement processing technique, multi-station molding can be achieved in a vacuum environment. Furthermore, by employing a three-chamber vacuum replacement method, the vacuum processing chamber 120 can be maintained in a vacuum state, improving the operational stability of the vacuum molding chamber 100 and reducing nitrogen consumption. The provision of an automatic loading mechanism 500 and unloading mechanism 600 enhances intelligent and unmanned operation.

[0154] In some embodiments, combined Figures 1 to 7 The transmission mechanism shown in the figure provides a control method for a transmission mechanism, which is used for the transmission mechanism described in any of the above embodiments. The transmission mechanism includes a first driving member and a second driving member, combined with Figure 17 As shown, the control method includes:

[0155] S1702, in response to the operation instruction, controlling the second driving member to rotate along the first direction to drive the conveying member to move from the first end to the second end of the mounting hole to clamp a workpiece to be processed on a processing table.

[0156] S1704: After controlling the first driving member and the second driving member to rotate synchronously by a preset angle, the workpiece to be processed is moved to the next adjacent processing table.

[0157] S1706, controlling the second driving member to rotate along the second direction to drive the conveying member to move from the second end of the mounting hole to the first end to release the workpiece to be processed.

[0158] The first direction and the second direction are opposite to each other, and the distance from the first end to the rotation center of the second rotating body is greater than the distance from the second end to the rotation center of the second rotating body.

[0159] The control method provided by the disclosed embodiments controls the operation of a first driving member and a second driving member to drive the first and second rotating bodies to rotate. Specifically, in response to an operation command, the second driving member is first controlled to rotate the second rotating body in a first direction, thereby rotating a mounting hole provided in the second rotating body. This in turn causes the movable portion of the conveying member to move relative to the mounting hole, such that the movable portion moves from the first end to the second end of the mounting hole, driving the guide rod of the conveying member toward the center of the second rotating body, thereby driving the gripping portion of the conveying member to grip the workpiece. After the workpiece is gripped, the first and second driving members are then controlled to rotate synchronously by a preset angle to the next station. After reaching the next station, the second driving member is again controlled to rotate the second rotating body in a second direction, thereby rotating the mounting hole, thereby moving the movable portion within the mounting hole from the second end to the first end of the mounting hole. Because 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 toward a side away from the center of the second rotating body, thereby driving the first and second gripping portions of the gripping portion to separate, thereby releasing the workpiece. The controller is installed to repeatedly control the first driving member and the second driving member in the above steps, thereby achieving the clamping, movement and release of the workpiece.

[0160] In some embodiments, combined Figures 8 to 16 The mold engraving device shown in the figure provides a control method for the mold engraving device, which is used for the mold engraving device as described in any of the above embodiments, combined with Figure 18 As shown, the control method includes:

[0163] S1806, when 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, respectively controlling the operation of the loading mechanism and controlling the operation of the unloading mechanism.

[0164] The control method of the molding device provided by the present disclosure is applied to the molding device of any of the above-mentioned embodiments. The control method provided by the present disclosure receives a loading and unloading request instruction. In response to the loading and unloading request, the processing chamber vacuum degree of the vacuum processing chamber, the loading chamber vacuum degree of the loading vacuum chamber, and the unloading chamber vacuum degree of the unloading vacuum chamber are respectively obtained. And according to the processing chamber vacuum degree, the loading chamber vacuum degree and the unloading chamber vacuum degree are adjusted so that the loading chamber vacuum degree and the unloading chamber vacuum degree are the same as the processing chamber vacuum degree. In this way, by keeping the vacuum degree in the three cavities consistent, the operation of the loading mechanism and the unloading mechanism is further controlled to complete the loading and unloading operation. The control method provided by the present disclosure can make the vacuum degree of the vacuum processing chamber, the loading vacuum chamber, and the unloading vacuum chamber consistent, avoid the difference in vacuum degree between the cavities, and improve the stability of controlling the operation of the loading mechanism and the unloading mechanism.

[0165] Optionally, the loading mechanism further includes a loading valve, and the step of controlling the operation of the loading mechanism includes: controlling the loading valve to open, and controlling the loading gripper to move the workpiece to be processed in the loading vacuum chamber into the vacuum processing chamber. After the workpiece is moved into the vacuum processing chamber, controlling the loading valve to close.

[0166] In this embodiment, the step of controlling the operation of the loading mechanism includes: 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 transfer 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. Controlling the loading valve to close completes the loading process.

[0167] Optionally, the unloading mechanism further includes a unloading valve, and the step of controlling the operation of the unloading mechanism includes: controlling the unloading valve to open, and controlling the unloading gripper to move the processed workpiece out of the vacuum processing chamber into the unloading vacuum chamber. After the workpiece is moved out, controlling the unloading valve to close.

[0168] In this embodiment, the vacuum level of the unloading vacuum chamber is controlled to be consistent with the vacuum level of the vacuum processing chamber to improve the smooth opening of the unloading valve. After the vacuum levels are adjusted to be consistent, the step of controlling the operation of the unloading mechanism includes: controlling the unloading valve to open, thereby connecting the unloading vacuum chamber with 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 operation.

[0169] Optionally, the unloading mechanism further includes a discharge valve and a discharge grabbing mechanism. After the discharge valve is closed, the mechanism further includes: controlling the pressure relief of the discharge vacuum chamber. After pressure relief is complete, the discharge valve is controlled to open, and the discharge grabbing mechanism is controlled to remove the processed workpiece from the discharge vacuum chamber through the discharge port onto the unloading tray. After removal, the discharge valve is controlled to close, and the discharge 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 smooth opening of the discharge valve. After depressurization, the discharge valve is controlled to open, and the unloading gripper mechanism removes the processed workpiece from the unloading vacuum chamber through the discharge port to the unloading tray. After removal, the discharge valve is controlled to close, 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 loading mechanism further includes a feed valve and a loading and grabbing mechanism. Prior to the step of obtaining a vacuum level in the vacuum processing chamber, the process further includes: controlling the pressure relief of the loading vacuum chamber and controlling the feed valve to open. The loading and grabbing mechanism is controlled to grab the workpiece to be processed and deliver it to the loading vacuum chamber. After delivery, the feed valve is controlled to close, and the loading vacuum chamber is evacuated.

[0172] In this embodiment, before loading the vacuum processing chamber, a loading and grabbing mechanism is controlled to load the vacuum processing workpiece. Specifically, this involves first depressurizing the loading vacuum chamber to improve the smooth opening of the feed valve. After depressurization, the feed valve is controlled to open, and the loading and grabbing mechanism is controlled to deliver the workpiece to be processed into the loading vacuum chamber through the feed port, and the feed valve is closed. The loading vacuum chamber is then evacuated until the vacuum level matches that of the vacuum processing chamber, ensuring the correct loading environment and smoother processing.

[0173] Optionally, before controlling the loading and grabbing mechanism to load the vacuum processing element, the process further includes obtaining first data on the workpieces to be processed within the loading tray of the loading mechanism. If the first data exceeds a first quantity threshold, the loading and grabbing mechanism is controlled to perform a grabbing operation. If the first data is less than or equal to the first quantity threshold, a restocking reminder is issued. This indicates that the number of workpieces to be processed on the loading tray is low and requires timely replenishment. This reminder provides timely alerts to personnel, thereby improving the continuity and stability of the entire processing process.

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

[0175] Optionally, after removing the processed workpiece from the unloading vacuum chamber and controlling the discharge valve to close, the control method further includes obtaining second data on the unloading tray. If the second data is greater than or equal to a second quantity threshold, issuing an unloading reminder. This promptly reminds the worker to replace the unloading tray with a new one to store the processed workpieces. If the second data is less than the second quantity threshold, controlling the unloading gripping mechanism to perform an unloading operation.

[0176] Optionally, after the steps of separately controlling the operation of the loading mechanism and the unloading mechanism, the process further includes: after placing the workpiece to be processed into the vacuum processing chamber, controlling the vacuum engraving chamber to close, and controlling the operation of the conveying mechanism to sequentially move the workpiece to be processed between the plurality of processing stations along the circumference of the vacuum processing chamber. When the workpiece to be processed moves to each processing station, controlling the operation of the servo loading system corresponding to the processing station to process the workpiece to be processed.

[0177] In this embodiment, the control method further includes: after the workpiece to be processed is placed in the vacuum processing chamber, the vacuum molding chamber is controlled to be closed so that the processing process of the optical glass is in a vacuum environment. The conveying mechanism is controlled to operate to drive the workpiece to be processed to complete the corresponding processing steps in sequence at multiple processing stations distributed along the circumference. Among them, the conveying mechanism drives the workpiece to be processed to move to each processing station, and then controls the servo loading system of the corresponding station to operate to process the workpiece to be processed. After completing the corresponding processing, the conveying mechanism is controlled to drive the workpiece to continue rotating to the next station, rotating in sequence, and completing the processing of the workpiece to be processed - optical glass - after one rotation.

[0178] By adopting the control method for the engraving device provided by the present disclosure, and by controlling the conveyor mechanism and servo loading system, a multi-station rotary arrangement processing process for optical glass is achieved by circumferentially arranging multiple processing stations along the vacuum engraving chamber. By coordinating the conveyor mechanism with the multiple processing stations and the multiple servo loading systems, the workpiece is able to rotate through the multiple processing stations 130 in sequence to complete the corresponding processing process, thereby improving processing efficiency, satisfying the vacuum processing environment, and enhancing the processing effect on optical glass.

[0179] Optionally, the transmission mechanism further comprises: a first driving member, the output end of the first driving member is connected to the first rotating body, for driving the first rotating body to rotate a second driving member, and the output end of the second driving member is connected to the second rotating body, for driving the second rotating body to rotate. The steps of controlling the operation of the transmission mechanism include:

[0180] Controlling the second driving member to rotate in a first direction to drive the conveying member to move from the first end to the second end of the mounting hole to clamp a workpiece to be processed on a processing station;

[0181] After controlling the first driving member and the second driving member to synchronously rotate at a preset angle, the workpiece to be processed is moved to the next adjacent processing station;

[0182] Controlling the second driving member to rotate in the second direction to drive the conveying member to move from the second end of the mounting hole to the first end to release the workpiece to be processed;

[0183] The first direction and the second direction are opposite to each other, and the distance from the first end to the rotation center of the second rotating body is greater than the distance from the second end to the rotation center of the second rotating body.

[0184] In this embodiment, the first and second driving members are controlled to operate to drive the first and second rotating bodies to rotate. Specifically, in response to an operation command, the second driving member is first controlled to rotate the second rotating body in a first direction, thereby rotating the mounting hole provided in the second rotating body. This in turn causes the movable portion of the conveyor member to move relative to the mounting hole, such that the movable portion moves from the first end to the second end of the mounting hole. This drives the guide rod of the conveyor member toward the center of the second rotating body, thereby driving the gripping portion of the conveyor member to grip the workpiece. After the workpiece is gripped, the first and second driving members are then controlled to rotate synchronously by a preset angle to the next station. After reaching the next station, the second driving member is again controlled to rotate the second rotating body in a second direction, thereby rotating the mounting hole. This in turn causes the movable portion within the mounting hole to move from the second end to the first end of the mounting hole. Because 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 toward a side away from the center of the second rotating body, thereby driving the first and second gripping portions of the gripping portion to separate, thereby releasing the workpiece. By repeatedly controlling the first driving member and the second driving member according to the above steps, the workpiece to be processed passes through multiple processing stations in sequence, thereby achieving the clamping, movement and release of the workpiece.

[0185] Optionally, the engraving device also includes a lifting mechanism, and after responding to the step of running the instruction, it also includes: obtaining workpiece information on the loading station and / or unloading station; according to the workpiece information, controlling the lifting mechanism to rise or fall to drive the loading station and the unloading station to move back and forth between the working position and the loading and unloading position.

[0186] In this embodiment, the workpiece information on the loading station and / or unloading station is obtained to determine whether loading and unloading operations are required. When it is determined that loading and unloading operations are required, the lifting mechanism is controlled to descend to the loading and unloading position, and an operating instruction is sent to control the vacuum molding chamber to open for loading and unloading. After the loading and unloading operations are completed, the lifting mechanism is controlled to rise to the working position so that the conveying mechanism can perform circumferential processing on the workpiece to be clamped. The loading station and the unloading station are driven to move back and forth between the working position and the loading and unloading position by controlling the lifting mechanism to improve the efficiency of loading and unloading. By controlling the coordination and cooperation of the lifting mechanism, the conveying mechanism and multiple processing stations, the continuous processing of the workpiece is realized, the continuity of the processing steps is improved, and the continuous processing of multiple processing steps can be realized to improve the production efficiency of optical glass.

[0187] Optionally, infrared sensors are located at corresponding positions on 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 controlled to descend to the loading and unloading position to perform loading and unloading. Once completed, the lifting mechanism is raised to the working position, where the conveyor mechanism rotates circumferentially, enabling continuous processing and improving efficiency.

[0199] S1911, respectively obtaining the vacuum degree of the loading vacuum chamber and the vacuum degree of the unloading vacuum chamber;

[0200] S1912, adjusting the vacuum degree of the loading vacuum chamber and the vacuum degree of the unloading vacuum chamber according to the vacuum degree of the processing chamber, 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;

[0201] S1913, control the loading valve to open, 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 loading valve to close.

[0202] S1914, control the unloading valve to open, and control the unloading gripper to move the processed workpiece out of the vacuum processing chamber into the unloading vacuum chamber; after moving out, control the unloading valve to close.

[0203] S1915, controls the lifting mechanism to rise, so as to drive the loading station and the unloading station to the working position.

[0206] S1918, controlling the second driving member to rotate in the second direction to drive the conveying member to move from the second end of the mounting hole to the first end to release the workpiece to be processed.

[0207] The first driving member and the second driving member are repeatedly controlled according to the above steps, so that the workpiece to be processed passes through multiple processing stations in sequence to the unloading station.

[0208] The steps of controlling the servo loading system corresponding to the processing station to process the workpiece to be processed specifically include:

[0209] When the workpiece is conveyed from the loading station to the preheating station via rotary conveyor, the servo loading system controlling the preheating station drives the upper die, which contains a resistance heating element, downward to contact the workpiece, and the upper and lower die begin heating. When the workpiece reaches the preheating temperature, the servo loading system controlling the preheating station drives the upper die upward, freeing it from the workpiece. The conveyor mechanism then moves the workpiece to the next station, the engraving station, completing the mold preheating process.

[0210] When the workpiece arrives at the die-engraving station, the servo loading system controls the die-engraving station, driving the upper die block equipped with a resistance heater downward to contact the workpiece. The upper and lower die blocks then begin heating. When the workpiece reaches the molding temperature, the servo loading system continues loading until the set pressure and displacement are achieved and maintained for a period of time. The servo loading system also controls the die-engraving station, driving the upper die block upward to release the workpiece. A transfer mechanism then transfers the workpiece to the next station, the holding pressure station, completing the initial molding process.

[0211] Once the workpiece reaches the holding station, the servo loading system controlling this station drives the upper die plate downward to contact the workpiece. The mold then begins to cool, while the servo loading system continues loading until the set holding pressure and displacement are reached. Once the workpiece reaches the holding temperature and remains there for a period of time, the servo loading system controlling the holding station drives the upper die plate upward, separating it from the workpiece. A transfer mechanism then transfers the workpiece to the next station, the cooling station, completing the second stage of the holding process.

[0212] When the workpiece reaches the cooling station, the servo loading system controlling the cooling station drives the upper module of the water-cooling module downward to contact the workpiece, and then the upper and lower modules start circulating water to cool the workpiece. When the workpiece temperature reaches the exit temperature, the servo loading system controlling the cooling station drives the upper module of the water-cooling module upward, separating it from the workpiece. The conveyor mechanism transfers the workpiece to the next station, the unloading station of the lifting mechanism, completing the mold cooling process.

[0213] After the workpiece completes all the molding processes, it returns to the unloading station of the lifting mechanism.

[0214] By adopting the control method for the engraving device provided in this disclosure, optical glass can be processed using a multi-station rotary arrangement process, thereby improving production efficiency.
