[0005]当用于对多个镜片模具并行操作时,多个吸盘需要同步翻转到指定位置,然而因机械手放置镜片模具的位置及翻转运动量不同,可能导致翻转后镜片模具的停留位置不一致
[0026] This embodiment integrates the loading and unloading processes, arranging the loading and unloading components alternately to coordinate with the second mold fixing component and the external robot arm for transferring the lens mold. During this process, the loading components need to rotate a certain angle and stop at either an upright position to cooperate with the external robot arm or a horizontal position to cooperate with the first mold fixing component. Multiple loading components are connected to a loading linkage rod via a loading connecting rod. The loading linkage rod is driven by a loading drive component, enabling the synchronous flipping of multiple loading components. A loading stop block limits the rotation of the loading components, and a first spring plate is installed between the loading connecting rod and the loading linkage rod to absorb excess momentum, ensuring that each loading component abuts against its corresponding loading stop block during the flipping process, reaching the designated position. This embodiment ensures that multiple lenses remain in the same position after flipping when flipping multiple lens molds.

Abstract
Description
Technical Field
[0001] This invention relates to the field of lens manufacturing equipment, and more particularly to a loading and unloading device with a flipping positioning structure. Background Technology
[0002] The lens mold includes mold A, mold B, and adhesive tape. There is a cavity between mold A and mold B. One end of the adhesive tape is bonded to mold A and mold B as the root, and then a ring is bonded around the perimeter of mold A and mold B to make the cavity closed.
[0003] To ensure a strong bond between the tape and molds A and B, the tape is wrapped around the circumference of the lens mold and then extended to form an excess covering portion, which is then bonded to the previous layer of tape. The length of this excess covering portion is approximately 70mm. Thus, the other end of the tape is the excess covering portion. When it is necessary to pour lens material into the mold cavity, a pulling force is applied to the other end of the tape along the circumference of the lens mold, causing a portion of the tape to separate from molds A and B and expose the sprue. Liquid lens material can then be poured into the mold cavity using a pouring tool. Therefore, the other end of the tape is often referred to as the tape head.
[0004] CN213947215U discloses a mold handling device for a lens casting machine, including a frame, a lead screw module, a stepper drive motor, a rotating mechanism, a pneumatic gripper for gripping the mold for loading, and a suction cup for removing the mold after casting. The lead screw module is horizontally fixedly mounted on the frame, and a mounting plate is fixedly connected to the moving block of the lead screw module. The stepper drive motor is fixedly mounted on the upper surface of the mounting plate. The base plate of the rotating mechanism is fixedly mounted on the mounting plate and located in front of the stepper drive motor. The rotating mechanism can rotate 90° under the drive of the stepper drive motor. The pneumatic gripper and the suction cup are arranged on the rotating mechanism, and the loading and unloading actions are realized as the rotating mechanism rotates.
[0005] When multiple lens molds are operated in parallel, multiple suction cups need to be synchronously flipped to designated positions. However, due to differences in the placement position and flipping motion of the lens molds by the robotic arm, the dwell positions of the lens molds after flipping may be inconsistent. In addition, when multiple lens molds are moved from the loading / unloading station to the casting station, there are cases where the heights of the lens molds are uneven. Inconsistent height and position of the lens molds will prevent the tape from being accurately gripped and torn to expose the injection port, thus affecting the quality of the lens raw materials subsequently poured into the injection port.

[0057] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0058] This embodiment provides a lens mold casting system, including a frame 200 and at least two sets of lens casting equipment. The frame 200 includes a first platform 201 and a second platform 202. The first platform 201 has a front region 203 and a rear region 204. The second platform 202 is located above the rear region 204 via a platform support 205. At least two sets of lens casting equipment are arranged side by side on the frame 200. Each set of lens casting equipment can perform feeding, tape removal, glue injection, tape sealing, and unloading operations on the lens mold 100. The lens casting equipment on the frame 200 can be added or removed as needed, providing good scalability.
[0059] Please see Figure 2 and Figure 3 Each lens casting equipment includes a loading and unloading device, a sealing tape tearing device, and a casting device. The loading and unloading device is located on the first platform 201, and the sealing tape tearing device and the casting device are located on the second platform 202. The loading and unloading device is used to fix the lens mold 100 below the sealing tape tearing device. The sealing tape tearing device is used to tear the tape on the lens mold 100 to expose the injection port. The casting device is used to inject glue into the injection port. The sealing tape tearing device is also used to attach the tape to the lens mold 100 and seal the injection port after the lens mold 100 has completed the glue injection.
[0060] Please see Figure 4The loading and unloading device includes a mold storage module 300, a mold positioning module 400, and a mold transfer module 500. The mold storage module 300 is located in the front area 203 of the first platform 201, and the mold positioning module 400 is located in the rear area 204 of the first platform 201. The mold transfer module 500 can move between the mold storage module 300 and the mold positioning module 400 to transport un-glued lens molds 100 from the mold storage module 300 to the mold positioning module 400, and to transport glued lens molds 100 from the mold positioning module 400 to the mold storage module 300.
[0061] The mold temporary storage module 300 includes a loading component 301, a unloading component 302, a loading drive mechanism 303, and an unloading drive mechanism 304. Multiple loading components 301 and multiple unloading components 302 are alternately arranged. The loading drive mechanism 303 drives the multiple loading components 301 to rotate synchronously, and the unloading drive mechanism 304 drives the multiple unloading components 302 to rotate synchronously. The mold positioning module 400 includes multiple first mold fixing components 401. The mold transfer module 500 includes a second mold fixing member 501 and a fixing member drive member. The second mold fixing member 501 is configured in a one-to-one correspondence with the first mold fixing member 401. The fixing member drive member is used to drive the second mold fixing member 501 to move between the mold temporary storage module 300 and the mold positioning module 400, so that the second mold fixing member 501 can transport the lens mold 100 on the loading member 301 to the first mold fixing member 401 for casting, and after casting, transport the lens mold 100 to the unloading member 302.
[0062] The first platform 201 is provided with a slide rail 206, which extends from the front region 203 to the rear region 204. The fixing member drive can drive the second mold fixing member 501 to move along the slide rail 206. The loading member 301, the unloading member 302 and the first mold fixing member 401 are located on the same side of the slide rail 206. The loading member 301 and the unloading member 302 are arranged alternately in a straight line along the length of the slide rail 206, and multiple first mold fixing members 401 are arranged in a straight line along the length of the slide rail 206. In specific implementation, the number of loading components 301, unloading components 302, first mold fixing components 401, and second mold fixing components 501 are the same and correspond one-to-one. The distances between two adjacent loading components 301, two adjacent unloading components 302, two adjacent first mold fixing components 401, and two adjacent second mold fixing components 501 are all equal. Furthermore, the distance between two adjacent loading components 301 is greater than the width of the unloading component 302, so that the loading components 301 and unloading components 302 can be alternately arranged. Figure 4As shown, two sets of loading and unloading devices are arranged side by side on the first platform 201. Each set of loading and unloading devices includes three loading components 301, three unloading components 302, three first mold fixing components 401 and three second mold fixing components 501.
[0063] This embodiment integrates the structures involved in lens casting processes—loading, tape removal, glue injection, tape sealing, and unloading—into a modular lens casting equipment. This allows for the addition or removal of equipment as needed, offering good scalability. Furthermore, by decoupling the modules, each casting unit has independent casting functionality, ensuring that a failure in one module will not affect the operation of others, thus guaranteeing production efficiency. In addition, multiple lens casting units are arranged side-by-side on a frame, with the loading and unloading structures integrated in the same area of the first platform, and the casting and tape removal structures integrated in the same area of the second platform. This horizontal and vertical structural layout design reduces space occupation and facilitates management.
[0064] Please see Figures 5-7 The mold temporary storage module 300 also includes a feeding bracket 305, which is fixed to the upper surface of the first platform 201 and corresponds one-to-one with the feeding loading component 301. The first platform 201 has feeding bracket through holes 208 corresponding to the feeding brackets 305. The feeding loading component 301 includes a feeding suction cup 307 and a first rotating shaft 308. The feeding suction cup 307 is fixedly connected to the first rotating shaft 308, which is rotatably connected to the feeding bracket 305. The end of the first rotating shaft 308 is connected to a feeding rotating block 325. The feeding bracket 305 is provided with a feeding stop block 319 that cooperates with the feeding rotating block 325. The feeding stop block 319 is located below the feeding rotating block 325 and has a first feeding stop part 320 and a second feeding stop part 321.
[0065] The feeding drive mechanism 303 includes a feeding drive component 311, a feeding connecting rod 312, and a feeding linkage rod 313. The feeding drive component 311 and the feeding linkage rod 313 are located below the first platform 201. The upper end of the feeding connecting rod 312 is connected to the feeding rotating block 325, and the lower end of the feeding connecting rod 312 passes through the feeding bracket through hole 208 and is connected to the feeding linkage rod 313. The feeding drive component 311 is fixed to the lower surface of the first platform 201, and the drive rod of the feeding drive component 311 is fixedly connected to the feeding linkage rod 313. The feeding drive component 311 drives the feeding linkage rod 313 to move up and down, thereby driving the first rotating shaft 308 to rotate, so that the feeding rotating block 325 abuts against the feeding stop block 319. Specifically, the feeding link 312 rises, causing the feeding rotating block 325 to rotate clockwise until it abuts against the first feeding stop 320 of the feeding stop block 319, so that the feeding loading component 301 is in a horizontal position that cooperates with the first mold fixing component 401; the feeding link 312 moves downward, causing the feeding rotating block 325 to rotate counterclockwise until it abuts against the second feeding stop 321 of the feeding stop block 319, so that the feeding loading component 301 is in an upright position that cooperates with the external robot arm. The angle between the horizontal and vertical positions of the feeding loading component 301 is 90°. This design uses the feeding linkage rod 313 to drive the rotation of each feeding link 312, ensuring synchronized flipping actions, and has a compact structure that saves on drive equipment. The cooperation between the feeding rotating block 325 and the feeding stop block 319 allows the feeding loading component 301 to stop at a designated position after flipping.
[0066] If the initial position of some loading components 301 before rotation is not in a vertical or horizontal position, then when the loading drive 311 drives the loading components 301 to rotate via the loading connecting rod 312, there will be a situation where the loading rotating block 325 of some loading components 301 has abutted against the loading stop block 319, while the loading rotating block 325 of some loading components 301 has not abutted against the loading stop block 319 (i.e., has not reached the designated position). To solve this problem, in this embodiment, the lower end of each loading connecting rod 312 is connected to the loading linkage rod 313 via a first spring. The first spring makes a soft connection between the loading connecting rod 312 and the loading linkage rod 313. The first spring can absorb excess momentum and drive the loading components 301 to abut against the loading stop block 319, so that the stopping position of each loading component 301 connected to the loading linkage rod 313 is consistent after rotation. Specifically, when the loading rotating block 325 of some loading components 301 has abutted against the loading stop block 319 (i.e., flipped into place), while the loading rotating block 325 of some loading components 301 has not abutted against the loading stop block 319 (failed to flip into place), the loading drive component 311 continues to drive the loading linkage rod 313 to move, causing the loading components 301 that have not flipped into place to continue rotating until they are flipped into place. The loading components 301 that have been flipped into place will cause the first spring to deform through the loading linkage rod 312, absorbing excess momentum and ensuring that all loading components 301 are flipped and stopped in the designated position. The setting of the first spring can also compensate for the height difference between the various loading linkage rods 312 caused by installation or process, reducing the installation and processing requirements of the loading linkage rods 312.
[0067] Correspondingly, the mold temporary storage module 300 also includes a material unloading bracket 306, which is fixed to the upper surface of the first platform 201 and corresponds one-to-one with the material unloading component 302. The first platform 201 has material unloading bracket through holes 209 corresponding one-to-one with the material unloading bracket 306. The material unloading component 302 includes a material unloading suction cup 309 and a second rotating shaft 310. The material unloading suction cup 309 is fixedly connected to the second rotating shaft 310. The second rotating shaft 310 is rotatably connected to the material unloading bracket 306. The end of the second rotating shaft 310 is connected to a material unloading rotating block 326. The material unloading bracket 306 is provided with a material unloading stop block 322, which is located below the material unloading rotating block 326. The material unloading stop block 322 has a first material unloading stop part 323 and a second material unloading stop part 324. The unloading drive mechanism 304 includes an unloading drive component 315, an unloading connecting rod 316, and an unloading linkage rod 317. The unloading drive component 315 and the unloading linkage rod 317 are located below the first platform 201. The upper end of the unloading connecting rod 316 is connected to the unloading rotating block 326, and the lower end of the unloading connecting rod 316 passes through the unloading bracket through hole 209 and connects to the unloading linkage rod 317. The unloading drive component 315 is fixed to the lower surface of the first platform 201, and the drive rod of the unloading drive component 315 is fixedly connected to the unloading linkage rod 317. The unloading drive component 315 drives the unloading linkage rod 317 to move up and down, thereby driving the second rotating shaft 310 to rotate, so that the unloading rotating block 326 abuts against the unloading stop block 322. Specifically, the feeding link 316 rises, causing the feeding rotating block 326 to rotate clockwise until it abuts against the first feeding stop 323 of the feeding stop block 322, so that the feeding loading component 302 is in a horizontal position that cooperates with the first mold fixing component 401; the feeding link 316 moves downward, causing the feeding rotating block 326 to rotate counterclockwise until it abuts against the second feeding stop 324 of the feeding stop block 322, so that the feeding loading component 302 is in an upright position that cooperates with the external robot arm. The angle between the horizontal and vertical positions of the feeding loading component 302 is 90°. This design uses the feeding linkage rod 317 to drive the rotation of each feeding link 316, ensuring synchronized flipping action, and has a compact structure that saves on drive equipment. Furthermore, the cooperation between the feeding rotating block 326 and the feeding stop block 322 allows the feeding loading component 302 to stop at a designated position after flipping.
[0068] In one possible implementation, the lower end of each feeding link 316 is connected to the feeding linkage rod 317 via a second spring. The second spring provides a flexible connection between the feeding link 316 and the feeding linkage rod 317. The second spring can absorb excess momentum, causing the feeding loading component 302 to abut against the feeding stop block 322, so that each feeding loading component 302 connected to the feeding linkage rod 317 stops at the same position after rotation. Specifically, when some feeding loading components 302 are rotated into place, while others are not, the feeding drive component 315 continues to drive the feeding linkage rod 317, causing the unrotated feeding loading components 302 to continue rotating until they are rotated into place. The feeding loading components 302 that have been rotated into place will deform through the feeding link 316, causing the second spring to absorb excess momentum, ensuring that all feeding loading components 302 are rotated and stop at the designated position. The second spring can also compensate for the height differences between the various feeding links 316 caused by installation or process, reducing the installation and processing requirements of the feeding links 316.
[0069] Please see Figure 4 The first platform 201 is also provided with a through groove 207 that runs through the upper and lower surfaces of the first platform 201. The length direction of the through groove 207 is consistent with the length direction of the slide rail 206. The mold transfer module 500 includes a first frame 503, which is slidably connected to the slide rail 206. The fixing member drive is fixed to the lower surface of the first platform 201. The drive rod of the fixing member drive passes through the through groove 207 and is connected to the first frame 503. It is used to drive the first frame 503 to translate along the slide rail 206 so that the second mold fixing member 501 can cooperate with the loading member 301, the unloading member 302 or the first mold fixing member 401.
[0070] The first frame 503 is provided with a second fixing bracket 505, which is arranged one-to-one with the second mold fixing component 501. Each second fixing bracket 505 includes a sleeve 510, a second mounting base 506, and a second lead screw 507. The sleeve 510 is fixed on the second mounting base 506. One end of the second connecting shaft 509 is connected to the second suction cup 508. The other end of the second connecting shaft 509 passes through the sleeve 510 and is connected to the second suction cup 508 drive. The second lead screw 507 enters the sleeve 510 and engages with the second connecting shaft 509. The second suction cup 508 drive is used to drive the second connecting shaft 509 to move linearly so that the second suction cup 508 moves closer to or away from the second mounting base 506.
[0071] The mold positioning module 400 includes a first fixing bracket 404, which is configured one-to-one with the first mold fixing component 401. Each first fixing bracket 404 includes a first mounting base 405 and a first lead screw 406. Each first mold fixing component 401 includes a first suction cup 407 and a first connecting shaft 408. The first mounting base 405 is fixedly mounted on the first platform 201. One end of the first connecting shaft 408 is connected to the first suction cup 407, and the other end of the first connecting shaft 408 passes through the first mounting base 405 and engages with the first lead screw 406.
[0072] When the second mold fixing member 501 moves to a position opposite to the first mold fixing member 401, a receiving space 414 for the lens mold 100 is formed between the first mold fixing member 401 and the second mold fixing member 501. Please refer to Figure 10 The mold positioning module 400 also includes a positioning block 402 and a positioning block 402 driver; the positioning block 402 is disposed on the first platform 201, and the positioning block 402 corresponds one-to-one with the first mold fixing member 401 and is located directly below the receiving space 414, and the distance from the supporting part of each positioning block 402 to the first platform 201 is equal; the positioning block 402 driver is disposed below the first platform 201 and is used to drive the positioning block 402 to synchronously approach the receiving space 414 to support the lens mold 100 released by the first mold fixing member 401 and the second mold fixing member 501.
[0073] In one possible implementation, the mold positioning module 400 further includes a positioning bracket 409, on which positioning blocks 402 are disposed. A positioning bracket through-hole 410 is provided on the first platform 201, and the driving rod of the positioning drive unit passes through the positioning bracket through-hole 410 and is fixedly connected to the positioning bracket 409. The positioning drive unit is used to drive the positioning bracket 409 to move up and down, thereby causing multiple positioning blocks 402 to move up and down synchronously, ensuring that the height of the supporting portion of each positioning block 402 is consistent before and after movement, thus ensuring that the height of each lens mold 100 supported by the supporting portion is consistent. The positioning block 402 has a supporting portion adapted to the outer side wall of the lens mold 100. The supporting portion includes a bottom wall 411 and a first side wall 412 and a second side wall 413 respectively connected to both sides of the bottom wall 411. When the positioning block 402 supports the lens mold 100, the outer side wall of the lens mold 100 contacts the bottom wall 411, the first side wall 412, and the second side wall 413. When the positioning block 402 supports the lens mold 100, there is a three-point contact between the lens mold 100 and the positioning block 402 to ensure stable support and avoid jamming when removing the lens mold 100 from the positioning block 402.
[0074] The operation process of the loading and unloading device in this embodiment includes:
[0075] The loading component 301 is in an upright position with the loading suction cup 307 facing upwards. An external robotic arm places the lens mold 100 to be glued onto the loading suction cup 307, which then holds the lens mold 100 in place. The loading drive mechanism 303 drives the loading component 301 to rotate 90° to a horizontal position. The fixing component drive drives the second mold fixing component 501 to move towards the loading component 301, so that the second suction cup 508 is opposite to the lens mold 100 held by the loading suction cup 307. The second suction cup 508 drive drives the second suction cup 508 closer to the lens mold 100, and simultaneously activates vacuum suction to hold the lens mold 100 in place. Then, the loading suction cup 307 disconnects its suction, and the second suction cup 508 drive drives the second suction cup 508 away from the loading suction cup 307, transferring the lens mold 100 from the loading suction cup 307 to the second suction cup 508. The fixing component drive drives the second mold fixing component 501 to move towards the first mold fixing component 401, so that the second suction cup 508 is opposite to the first suction cup 407 of the first mold fixing component 401. The second suction cup 508 drive drives the second suction cup 508 to move closer to the first suction cup 407. The first suction cup 407 and the second suction cup 508 respectively suck up one side of the lens mold 100. At this time, the lens mold 100 is directly above the positioning block 402. The positioning block 402 drive drives the positioning block 402 to move upward to the designated position. The suction of the first suction cup 407 and the second suction cup 508 is disconnected, so that the lens mold 100 is supported by the positioning block 402. At this time, all lens molds 100 are at the same height. The vacuum suction is activated so that the first suction cup 407 and the second suction cup 508 simultaneously suck up the lens mold 100. The loading operation is then completed.
[0076] After the lens mold 100 completes the glue injection and seals the injection port, the first suction cup 407 disconnects its suction. The second suction cup 508 driver drives the second suction cup 508 to carry the lens mold 100 away from the second suction cup 508. The fixing driver drives the second mold fixing member 501 to move to the lower loading member 302, so that the second suction cup 508 is opposite to the lower suction cup 309. The second suction cup 508 driver drives the second suction cup 508 to move closer to the lower suction cup 309. The lower suction cup 309 sucks on the lens mold 100. At the same time, the second suction cup 508 disconnects its suction. The fixing driver drives the second mold fixing member 501 to move to the upper loading member 301 to repeat the above steps to transfer the lens mold 100 on the upper suction cup 307 to the first mold fixing member 401. Meanwhile, the lowering drive mechanism 304 drives the lower loading member 302 to rotate 90° to the upright position. The external robot arm takes the lens mold 100 from the lower loading member 302.
[0077] This embodiment integrates the loading and unloading processes, arranging the loading and unloading components alternately to coordinate with the second mold fixing component and the external robot arm for transferring the lens mold. The loading and unloading components are located in the same area, saving equipment space. Furthermore, the loading and unloading components can share the external robot arm, eliminating the need for separate loading and unloading robots; a small configuration is sufficient to complete the loading and unloading actions. The loading and unloading components interact with the first mold fixing component and the external robot arm through rotation, resulting in simple and rapid movements, increased loading and unloading speed, reduced waiting time, and improved work efficiency.
[0078] In this embodiment, multiple loading components are connected to a loading linkage rod via a loading connecting rod. A loading drive component drives the loading linkage rod, enabling the synchronous flipping of multiple loading components. A loading stop block limits the rotation of the loading components, and a first spring plate is installed between the loading connecting rod and the loading linkage rod to absorb excess momentum, ensuring that each loading component abuts against its corresponding loading stop block during the flipping process, reaching the designated position. When used to flip multiple lens molds, this ensures that the lenses remain in the same position after flipping.
[0079] Please see Figures 11-13The adhesive tape tearing device includes a rotary drive mechanism 600, an adhesive tape tearing robot 700, a drive component for the adhesive tape tearing robot 700, and an adhesive tape sealing mechanism 800. The rotary drive mechanism 600 is mounted on the first platform 201 and is used to drive the first mold fixing member 401 and the second mold fixing member 501 to rotate synchronously, so that the lens mold 100, which is jointly fixed by the first mold fixing member 401 and the second mold fixing member 501, rotates. A tape-tearing robot 700 is mounted on the second platform 202 and located between the first platform 201 and the second platform 202. The tape-tearing robot 700 is configured one-to-one with the first mold fixing member 401. Each tape-tearing robot 700 includes a tape gripper 701, a clamping drive member 702, and a tape detection member 703. The tape detection member 703 is used to sense the tape end 101 on the lens mold 100. The clamping drive member 702 is used to drive the tape gripper 701 to open and close to clamp the tape end 101. The clamping drive member 702 and the rotary drive mechanism 600 can be selectively started or stopped according to the detection result of the tape detection member 703 to clamp the tape end 101 on the lens mold 100. The tape-tearing robot 700 drive member is used to drive the tape-tearing robot 700 to translate as a whole to tear the tape and expose the glue injection port. The sealing tape mechanism 800 includes a tape pressing block 801 and a pressing block driving component. The tape pressing block 801 is arranged in a one-to-one correspondence with the second mold fixing component 501. The pressing block driving component is used to drive the tape pressing block 801 to translate, so that the tape pressing block 801 abuts against the tape of the lens mold 100, thereby cooperating with the rotation of the lens mold 100 to attach the tape to the lens mold 100 and seal the glue injection port.
[0080] Please see Figure 9The first platform 201 has a first docking hole 210 and a second docking hole 211. The first docking hole 210 corresponds to the first lead screw 406 and is located directly below the first lead screw 406. The second docking hole 211 corresponds to the second lead screw 507 and is located directly below the second lead screw 507. The rotary drive mechanism 600 includes a rotary support 601, a first connecting rod 602, a second connecting rod 603, a rotary drive component 604, and a lifting drive component. The rotary support 601, the first connecting rod 602, the second connecting rod 603, the rotary drive component 604, and the lifting drive component are all located below the first platform 201. The first connecting rod 602 and the second connecting rod 603 are mounted on the rotary support 601. The lifting drive component is fixed to the lower surface of the first platform 201, and its drive rod is connected to the rotary support 601 to drive the rotary support 601 closer to the first platform 201, so that the first connecting rod 602 passes through the first docking hole 210 and docks with the first lead screw 406, and the second connecting rod 603 passes through the second docking hole 211 and docks with the second lead screw 507. The rotary drive component 604 is mounted on the rotary support 601 and drives the first connecting rod 602 and the second connecting rod 603 to rotate synchronously, thereby driving the first mold fixing component 401 and the second mold fixing component 501 to rotate synchronously.
[0081] In one possible implementation, a first roller 606 is provided on the first connecting rod 602, and a second roller 607 is provided on the second connecting rod 603. A belt 608 is tensioned between the first roller 606 and the second roller 607. The drive rod of the rotary drive member 604 is connected to either the first connecting rod 602 or the second connecting rod 603. After the first connecting rod 602 is connected to the first lead screw 406 and the second connecting rod 603 is connected to the second lead screw 507, the rotary drive member 604 operates, driving the first lead screw 406 and the second lead screw 507 to rotate synchronously. The first lead screw 406 drives the first connecting shaft 408 and the first suction cup 407 to rotate, and the second lead screw 507 drives the second connecting shaft 509 and the second suction cup 508 to rotate. The belt 608 transmission ensures that the first suction cup 407 and the second suction cup 508 rotate synchronously, making the lens mold 100 rotate smoothly.
[0082] The tape-tearing robot 700 includes a base 704, which has a bottom plate 705 and a side plate 706. The side plate 706 is fixed to the rear end of the bottom plate 705, and the clamping drive 702 is connected to the side plate 706. The adhesive tape gripper 701 includes an upper gripper 708, a lower gripper 709, and a support plate 710. The support plate 710 is located at the front end of the base plate 705. The lower gripper 709 has a lower gripper connecting end 711 and a lower gripper holding end 712. The upper gripper 708 has an upper gripper connecting end 713 and an upper gripper holding end 714. The lower gripper connecting end 711 is fixedly connected to the front end of the support plate 710. The middle part of the upper gripper 708 is rotatably connected to the front end of the support plate 710. The upper gripper connecting end 713 is connected to a clamping drive member 702. The clamping drive member 702 is used to drive the upper gripper 708 to rotate so that the upper gripper holding end 714 moves closer to or away from the lower gripper holding end 712. The adhesive tape detection member 703 is located on the lower gripper 709 and close to the lower gripper holding end 712.
[0083] In one possible implementation, the tape-tearing robot 700 further includes a gripper drive 715 and a glue inlet detection component 716. The glue inlet detection component 716 is located at the lower end of the base plate 705 and is used to sense the exposed glue inlet on the lens mold 100. The front end of the base plate 705 is provided with a sliding groove 707, and the gripper drive 715 is connected to the side plate 706. The rear end of the support plate 710 is slidably connected to the sliding groove 707, and the support plate 710 is fixedly connected to the gripper drive 715. The gripper drive 715 can drive the support plate 710 to move along the sliding groove 707, so as to move the tape gripper 701 away from or towards the glue inlet detection component 716. In this embodiment, the gripper drive 715 can fine-tune the tape gripper 701 based on the detection result of the glue inlet detection component 716, so that the length of the tape torn from each lens mold 100 is consistent, and the exposed glue inlets are of the same size and in the same position.
[0084] In one possible implementation, the lower clamping piece 709 is further provided with a limiting member 717, which protrudes from the upper clamping piece 708. A tape detection member 703 is located between the limiting member 717 and the lower clamping piece holding end 712, and is closer to the limiting member 717. The limiting member 717 is used to prevent the tape end 101 of the lens mold 100 from moving towards the lower clamping piece connecting end 711. The tape detection member 703 is used to sense the tape end 101 on the lens mold 100 when it abuts against the limiting member 717. By setting the limiting member 717 to restrict the movement of the tape end 101, when the tape end 101 abuts against the limiting member 717, the tape detection member 703 detects the tape end 101. At this time, the tape grippers 701 actuate to clamp the tape end 101, ensuring that the length of the tape clamped by each gripper is consistent, guaranteeing that the torn tape length is the same, and that the size and position of the exposed glue inlet are consistent.
[0085] In one possible implementation, the lower clamp 709 has an arcuate guide surface 718 at its lower part, which extends from the clamping end 712 of the lower clamp to the limiting member 717 for guiding the movement of the adhesive tape head end 101.
[0086] By setting limiting components and adhesive tape detection components at similar positions on the lower clamping plates of the adhesive tape gripper, the drive mechanism drives multiple lens molds to rotate synchronously, causing the adhesive tape head of the lens mold to move upward along the lower clamping plates, abutting against the limiting components and reaching the adhesive tape detection component. At this time, the adhesive tape detection component senses the adhesive tape head and triggers the clamping drive component to drive the upper and lower clamping plates to close and clamp the adhesive tape head. The adhesive tape tearing robot grips the adhesive tape head and moves as a whole, causing the adhesive tape of each lens mold to be torn open and exposing the glue injection port. At this time, the glue injection port detection component detects the glue injection port. When no glue injection port is detected, the adhesive tape gripper is finely adjusted relative to the glue injection port detection component to drive the adhesive tape to continue moving, so that the glue injection ports exposed by multiple lens molds are similar in size and consistent in position, which can improve the accuracy of subsequent glue injection operations.
[0087] See Qing Figure 8 The adhesive tape sealing mechanism 800 includes a second frame 803, which is sleeved outside the first frame 503. The second frame 803 is slidably connected to the slide rail 206. Adhesive tape pressing blocks 801 are disposed on the second frame 803 and correspond one-to-one with the second mold fixing members 501. The driving rod of the pressing block driving member is fixedly connected to the second frame 803 and is used to drive the second frame 803 to translate relative to the first frame 503, so that the adhesive tape pressing blocks 801 move closer to or further away from the corresponding second mold fixing members 501. In this embodiment, the second frame 803 is sleeved outside the first frame 503, and the two frames share the same slide rail 206, resulting in a novel structure and high integration. The adhesive tape pressing blocks 801 can achieve action coordination with the second mold fixing members 501 through one-dimensional movement, simplifying the structural design and ensuring the accuracy of the action.
[0088] The working process of the adhesive tape tearing device includes:
[0089] The first suction cup 407 and the second suction cup 508 respectively adhere to one side of the lens mold 100. The lifting drive unit drives the first lead screw 406 to engage with the first connecting rod, and the second lead screw 507 to engage with the second connecting rod 603. The tape-tearing robot arm 700 approaches the lens mold 100, and the tape gripper 701 opens and faces the tape on the side of the lens mold 100. The rotation drive unit 604 drives the first connecting rod 602 and the second connecting rod 603 to rotate synchronously, causing the first suction cup 407 and the second suction cup 508 to jointly adhere to the first connecting rod 407. The lens mold 100 rotates, and the tape end 101 of the lens mold 100 moves along the arc-shaped guide surface 718 of the lower clamping piece 709 of the tape gripper 701 until it abuts against the limiting member 717. At this time, the tape detection member 703 senses the tape end 101, and the rotation drive member 604 stops driving based on the detection result of the tape detection member 703. The lens mold 100 stops rotating, and the clamping drive member 702 drives the tape gripper 701 to close based on the detection result of the tape detection member 703, clamping the tape end 101. The tape-tearing robot 700 is driven by a drive unit to move the entire robot 700 horizontally. Each glue inlet detection unit 716 detects the glue inlet. If a glue inlet detection unit 716 does not detect a glue inlet, the gripper drive unit 715 drives the tape gripper 701 to move, carrying the tape, to tear a longer piece of tape. During the tape tearing process, the lens mold 100 is rotated until the exposed glue inlet is below the glue inlet detection unit 716. When the glue inlet detection unit 716 detects the glue inlet, the gripper drive unit 715 stops driving, ensuring that the size and position of the exposed glue inlets of each lens mold 100 are consistent. The tape gripper 701 releases the tape head 101, which is then supported by the tape pressing block 801. Subsequently, the glue injector 902 of the casting device injects glue into the glue inlet. After the glue injection is completed, the pressure block drive drives the second seat frame 803 to move horizontally, so that the adhesive tape pressure block 801 abuts against the outer wall of the adhesive tape of the lens mold 100. The rotation drive 604 drives the first connecting rod 602 and the second connecting rod 603 to rotate synchronously in opposite directions. During the rotation, the adhesive tape is squeezed by the adhesive tape pressure block 801 and adhered to the lens mold 100, sealing the glue injection port.
[0090] The lens casting system also includes a support platform 212, a robotic arm lifting drive 213, a tape-tearing robotic arm bracket 214, a casting robotic arm bracket 215, and a driving component for the casting robotic arm bracket 215. The support platform 212 is located between the first platform 201 and the second platform 202. The robotic arm lifting drive 213 is located on the second platform 202, and its drive rod is connected to the support platform 212 to drive the platform 212 to move vertically. The casting robotic arm bracket 215 is slidably connected to the lower surface of the support platform 212. The driving component for the casting robotic arm bracket 215 is connected to the casting robotic arm bracket 215 to drive the casting robotic arm bracket 215 to translate relative to the support platform 212. The casting robot 900 is located on the casting robotic arm bracket 215. The tape-tearing robot support 214 is slidably connected to the casting robot support 215. A drive unit for the tape-tearing robot support 214 is connected to the support and is used to drive the tape-tearing robot support 214 to translate relative to the casting robot support 215. The tape-tearing robot 700 is mounted on the tape-tearing robot support 214. In this embodiment, the tape-tearing robots 700 of multiple lens casting equipment can be mounted on the tape-tearing robot support 214, and the casting robots 900 of multiple lens casting equipment can be mounted on the casting robot support 215, thereby reusing the drive unit and saving cost and space.
