[0048] Please refer to Figure 1 、 Figure 2 、 Figures 7 to 10 As shown, this embodiment discloses a lens assembly machine for assembling lenses, which includes a variety of materials, including a lens barrel and a variety of components installed in the lens barrel. The lens assembly machine includes a feeding module 10, an angle transfer mechanism 300, a material picking mechanism 400 and an assembly module 500. The feeding module 10 is suitable for providing a variety of materials; the angle transfer mechanism 300 is provided on the side of the feeding module 10, and the angle transfer mechanism 300 includes a plurality of positioning platforms 310 and a first rotating drive member 320. Different positioning platforms 310 are adapted to different materials, and the positioning platforms 310 are suitable for rotating under the drive of the first rotating drive member 320; the material picking mechanism 400 connects the feeding module 10 and the angle transfer mechanism 300. The material picking mechanism 400 includes a material picking turntable 410, a material picking moving module 420 and a plurality of material picking nozzles 430. The material picking turntable 410 is rotatably connected to the material picking moving module 420. The material picking turntable 410 can move under the drive of the material picking moving module 420. The plurality of material picking nozzles 430 are connected to the material picking turntable 410 and are arranged around the rotation axis of the material picking turntable 410. The material picking nozzles 430 at different positions are adapted to one of a plurality of materials; the assembly module 500 includes an assembly and transport mechanism 510 and an assembly loading platform mechanism 520. The assembly and transport mechanism 510 connects the angle transfer mechanism 300 and the first end of the assembly loading platform mechanism 520, and is suitable for transporting materials to the assembly loading platform mechanism 520 for assembly.

[0049] According to the lens assembly machine of the embodiment of the present invention, the material picking moving module 420 drives the material picking turntable 410 to move above the material in the feeding module 10, and one of the multiple material picking nozzles 430 on the material picking turntable 410 picks up the material. After the suction is completed, the material picking moving module 420 drives the material picking turntable 410 to drive the material picking nozzle 430 to move above the next hooking material conveying mechanism 200, and the material picking turntable 410 rotates so that the empty material picking nozzle 430 corresponds to the next material, and the above process is repeated until each material is sucked into the material picking turntable 410. Under the drive of the material picking moving module 420, the material picking turntable 410 transports all the sucked materials to the angle transfer mechanism 300, and places the sucked multiple materials one by one on the corresponding positioning platform 310, and the first rotating drive component 320 drives the positioning platform 310 to rotate and drive the material to rotate to the set angle, and the assembly and transportation mechanism 510 transports the material from the positioning platform 310 to the assembly loading platform mechanism 520 for assembly.

[0050] It should be noted that in the related art, lens assembly machines are used for loading and assembling a variety of materials, and usually different conveying mechanisms are used for different materials. Each conveying mechanism has an independent driving module (mechanical arm, mobile module, etc.) and a conveying module (gripper or suction nozzle, etc.), resulting in that the space for the structure required for material handling in the overall volume of the existing lens assembly machine is too large, and the volume of the feeding module 10 is greatly limited when the volume of the lens assembly machine remains unchanged, resulting in only a smaller number of types of materials being able to be installed; and when assembling lenses with a variety of materials, if the conveying mechanism of the existing technology is used, there will be too many conveying mechanisms in the lens assembling machine, resulting in the problem of excessive volume of the lens assembling machine structure, or the material of a lens is split into multiple groups and assembled multiple times on different lens assembling machines, resulting in low lens head assembly efficiency.

[0051] According to the lens assembly machine of the embodiment of the present invention, a material picking mechanism 400 is used to connect the material feeding module 10 and the angle transfer mechanism 300, and an assembly transport mechanism 510 is used to connect the angle transfer mechanism 300 and the assembly loading platform mechanism 520 to achieve automated lens assembly. Furthermore, by providing multiple material picking nozzles 430 on the material picking turntable 410, multiple materials can be picked up at one time and simultaneously transferred to the angle transfer mechanism 300, effectively reducing the repeated handling cycle of different materials and improving the assembly production efficiency of the lens. Only one material picking moving module 420 is required to handle multiple materials, improving the integration of the material picking mechanism 400, effectively reducing the volume occupied by the material handling-related structures in the lens assembly machine, and correspondingly increasing the volume occupied by the material feeding module 10 to expand the number of materials, thereby enabling the assembly of a larger number of lenses. Furthermore, the positioning platform 310 of the angle transfer mechanism 300 pre-rotates different materials to corresponding set angles, improving the efficiency of the assembly transport mechanism 510 in handling and placing the materials on the assembly loading platform mechanism 520 for assembly.

[0052] In this embodiment, the material picking turntable 410 is connected to ten material picking nozzles 430, and each material picking nozzle 430 corresponds to a different type of material; in other embodiments, the number of material picking nozzles 430 connected to the material picking turntable 410 can be adjusted based on the adaptability of the materials required for lens assembly, and multiple material picking nozzles 430 of the same type can also be connected to the material picking turntable 410 for transporting multiple materials of the same type at a time.

[0053] In some embodiments, combined Figure 1 、 Figure 3 and Figure 6 As shown, the assembly loading platform mechanism 520 includes an assembly loading platform 521 and an assembly loading platform linear module 522, and the assembly loading platform 521 is suitable for moving from the first end to the second end of the assembly loading platform mechanism 520 under the drive of the assembly loading platform linear module 522; the assembly module 500 also includes a dispensing mechanism 530 and a dispensing platform mechanism 540, and the dispensing mechanism 530 includes a dispensing head assembly 531, a dispensing conveying clamp 532 and a dispensing linear module 533, and the dispensing linear module 533 can drive the dispensing conveying clamp 532 to move, so as to convey the lens on the assembly loading platform 521 to the dispensing platform mechanism 540; the dispensing head assembly 531 is suitable for dispensing glue on the lens on the dispensing platform mechanism 540; the dispensing linear module 533 is set at an angle to the assembly loading platform linear module 522.

[0054] In this embodiment, after the lens is assembled within assembly platform 521 on the first end of assembly platform linear module 522, it is driven by assembly platform linear module 522 to move to the second end. Driven by dispensing linear module 533, dispensing and transporting gripper 532 moves above assembly platform 521, grips and transports the lens to dispensing platform mechanism 540. Dispensing head assembly 531 dispenses and cures the lens on dispensing platform mechanism 540. By providing dispensing mechanism 530 to dispense and cure the assembled lens, lens production efficiency is improved. Dispensing platform mechanism 540 is used to position the lens, assisting dispensing head assembly 531 in achieving precise dispensing.

[0055] In this embodiment, the dispensing linear module 533 extends along the Y direction shown in the figure, and the assembly loading platform linear module 522 extends along the X direction shown in the figure. Of course, the two can also be set at other angles.

[0056] In other embodiments, the dispensing and handling gripper 532 and the assembly loading platform 521 may be driven by a robotic arm.

[0057] In some embodiments, combined Figure 3 and Figure 6As shown, the dispensing head assembly 531 is connected to the movable end of the dispensing linear module 533, which drives the dispensing head assembly 531 to move. Driven by the dispensing linear module 533, the dispensing head assembly 531 can move to accommodate dispensing of lenses of different sizes and dispensing positions. Sharing the dispensing linear module 533 with the dispensing handling clamp 532 reduces the size of the dispensing mechanism 530 and improves the integration of the lens assembly machine.

[0058] In some embodiments, combined Figure 1 、 Figure 3 and Figure 5 As shown, the assembly module 500 also includes a blanking mechanism 550; the dispensing mechanism 530 also includes a blanking nozzle 534, which is connected to the dispensing linear module 533, and the blanking nozzle 534 connects the dispensing platform mechanism 540 and the blanking mechanism 550.

[0059] In this embodiment, the glued lens on the dispensing stage mechanism 540 is sucked by the discharge nozzle 534 and transported to the discharge mechanism 550 by the drive of the dispensing linear module 533, leaving the lens assembly machine. The discharge nozzle 534, the dispensing transport gripper 532, and the dispensing head assembly 531 share the dispensing linear module 533, reducing the size of the dispensing mechanism 530 and improving the integration of the lens assembly machine.

[0060] In some embodiments, combined Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the unloading mechanism 550 includes an unloading placement table 551, an unloading lifting module 552 and an unloading conveying mechanism 553; the unloading placement table 551 is provided with a first unloading placement position and a second unloading placement position arranged in a vertical direction, the first unloading placement position is suitable for placing a material cage for carrying a lens, and the second unloading placement position is suitable for placing a material cage for carrying a lens barrel; the unloading lifting module 552 can drive the unloading placement table 551 to rise and fall; the unloading conveying mechanism 553 is suitable for transporting the loading tray in the material cage and transferring it to the working range of the dispensing mechanism 530.

[0061] In this embodiment, when the lens assembly machine starts to run, the unloading conveying mechanism 553 transports the loading tray carrying the lens barrel from the second unloading placement position to the working range of the dispensing mechanism 530. At this time, the unloading conveying mechanism 553 has a loading tray carrying the lens barrel and an empty loading tray for carrying the lens. The dispensing conveying claw 532 transports the lens barrel on the loading tray to the assembly loading platform 521, and the assembly loading platform mechanism 520 drives the lens barrel to the first end for assembly; the lens with glued on the dispensing platform mechanism 540 is adsorbed and transported by the unloading suction nozzle 534 to the empty loading tray for carrying the lens on the unloading conveying mechanism 553. After being fully loaded, the unloading conveying mechanism 553 transports the loading tray to the material cage of the first unloading placement position to complete unloading, and the unloading lifting module 552 is driven to realize the connection between the material cage of the first unloading placement position or the material cage of the second unloading placement position and the unloading conveying mechanism 553.

[0062] In this embodiment, unlike the conventional lens assembly machine in which the unloading mechanism 550 is only used for unloading, a first unloading placement position for unloading lenses and a second unloading placement position for loading lens barrels are set in the unloading placement table 551, and the dispensing mechanism 530 and the unloading mechanism 550 are used in conjunction to realize the unloading of lenses and the loading of lens barrels, thereby effectively improving the production efficiency of lenses; and the front end (cage loading mechanism 100, hook material conveying mechanism 200) does not need to load lens barrels, and a larger number of materials can be set to further increase the types of lenses that can be adapted to the lens assembly machine.

[0063] In this embodiment, the lens assembly machine is provided with ten material cage placement tables 120 along the Y direction. Each material cage placement table 120 has two layers, with one material cage placed on each layer, which means that twenty kinds of materials can be loaded at one time. Combined with the lens barrel loaded by the unloading mechanism 550, the lens assembly machine of this embodiment can adapt to lenses with a maximum of twenty-one parts.

[0064] In other embodiments, the lens barrel may be loaded by the material cage loading mechanism 100 , and the amount of material contained in the lens needs to be reduced accordingly.

[0065] In some embodiments, combined Figure 5 As shown, the unloading conveying mechanism 553 includes a unloading conveying platform 5531 and a unloading pushing assembly 5532. The unloading conveying platform 5531 and the unloading pushing assembly 5532 are respectively located on both sides of the unloading placement platform 551. The unloading pushing assembly 5532 can push the loading tray in the material cage to move to the unloading conveying platform. The unloading conveying platform 5531 is provided with multiple sets of rollers, which can support the loading tray and drive the loading tray to move.

[0066] In this embodiment, the material unloading pushing assembly 5532 pushes the loading tray on the material unloading placement table 551 so that the loading tray contacts the rollers of the material unloading conveying platform 5531 , and the rolling of the rollers drives the loading tray to separate from the material unloading placement table 551 .

[0067] In other embodiments, the structure of the hook material conveying mechanism 200 mentioned above can also be adopted to realize the transportation of the material loading tray.

[0068] In this embodiment, the blanking and pushing component 5532 can be a cylinder, a slide module, etc.

[0069] In one embodiment, combined Figure 3 As shown, the assembly loading platform 521 includes a positioning shaft 5211 and a positioning clamp 5212. A positioning surface is provided at one end of the positioning shaft 5211, and the positioning surface is suitable for abutting against the lens. The positioning shaft 5211 is provided with a vacuum channel, and the vacuum channel is suitable for connecting an external vacuum air source with the lens. The positioning clamp 5212 is suitable for clamping the lens.

[0070] In this embodiment, when there is a need to assemble the lens, the lens barrel is placed on the positioning surface of the positioning shaft 5211 and is clamped and positioned by the positioning clamp 5212. After the positioning is completed, the negative pressure gas in the vacuum channel adsorbs the lens barrel and fixes it to the positioning shaft 5211 to ensure the positioning accuracy during the lens assembly process.

[0071] In one embodiment, combined Figure 3 As shown, the dispensing platform mechanism 540 includes a dispensing platform 541 and a platform rotation component (not shown in the figure), and the platform rotation component can drive the dispensing platform 541 to rotate.

[0072] In this embodiment, the dispensing rotation component can use a stepper motor, a servo motor, etc. as a power source.

[0073] In this embodiment, by combining the rotatable dispensing platform 541 with the dispensing head assembly 531 driven by the dispensing linear module 533, various dispensing methods such as arc dispensing and interpolation dispensing can be realized, effectively adapting to lenses with different process requirements.

[0074] In some embodiments, combined Figure 3 As shown, the dispensing mechanism 530 further includes a dispensing height detection module 535, which is disposed on one side of the dispensing stage mechanism 540 and is used to detect the dispensing height of the dispensing head assembly 531. This ensures that the dispensing position of the dispensing head assembly 531 is consistent with the dispensing position on the lens, preventing the dispensing amount from being too little or exceeding the standard.

[0075] In this embodiment, the height detection module may adopt a visual camera, and of course, a laser sensor, a proximity switch, etc. may also be adopted.

[0076] In some embodiments, combined Figure 1 、 Figure 2 and Figures 7 to 10As shown, the feeding module 10 includes a plurality of material cage loading mechanisms 100 and a plurality of hooking material conveying mechanisms 200; the material cage loading mechanism 100 includes a material cage placing platform 120, which is suitable for placing the material cage, and a loading tray is provided in the material cage, and the loading trays in different material cage loading mechanisms 100 are used to carry one of a plurality of materials; the hooking material conveying mechanism 200 corresponds one-to-one to the material cage loading mechanism 100, and the first end of the hooking material conveying mechanism 200 is adjacent to the material cage loading mechanism 100, and the hooking material conveying mechanism 200 is suitable for hooking the loading tray and transferring it from the first end to the second end.

[0077] In this embodiment, the lens contains a variety of materials (lens barrels or components) which are first arranged in a loading tray of a material cage, which is hooked from the material cage by the material hooking conveying mechanism 200 and transferred to the second end of the material hooking conveying mechanism 200, and the material picking moving module 420 drives the material picking turntable 410 to move above a material hooking conveying mechanism 200, and one of the multiple material picking nozzles 430 on the material picking turntable 410 sucks the material. After the suction is completed, the material picking moving module 420 drives the material picking turntable 410 to drive the material picking nozzle 430 to move to the next material hooking conveying mechanism 200, and the material picking turntable 410 is rotated to rotate. The disk 410 rotates so that the empty material picking nozzle 430 corresponds to the next material, and the above process is repeated until each material is sucked into the material picking turntable 410. Under the drive of the material picking moving module 420, the material picking turntable 410 transports all the sucked materials to the angle transfer mechanism 300, and places the sucked multiple materials one by one on the positioning platform 310. The first rotating drive member 320 drives the positioning platform 310 to rotate and drives the material to rotate to the set angle. The assembly and transportation mechanism 510 transports the material from the positioning platform 310 to the assembly loading platform mechanism 520 for assembly.

[0078] In this embodiment, the line can be changed by simply replacing the loading tray based on different types of lenses, effectively improving the line change efficiency of the assembly machine.

[0079] In this embodiment, the lens assembly machine is provided with ten material cage placement tables 120, with five material cage placement tables 120 in a group, and each group is provided with an angle transfer mechanism 300 and a material picking mechanism 400. Of course, in other embodiments, the number of material cage placement tables 120 and the corresponding relationship between the material cage placement tables 120, the angle transfer mechanism 300 and the material picking mechanism 400 can also be adaptively adjusted based on the material requirements in the lens.

[0080] In this embodiment, the material cage loading mechanism 100 also includes a material cage lifting component. Each material cage placement platform 120 is provided with two material cages in the vertical direction. The material cage placement platform 120 is driven to rise and fall by the material cage lifting component so that the loading plate in the material cage and the hook conveying mechanism 200 are connected.

[0081] In this embodiment, the hook material conveying mechanism 200 may include a hook for pulling the material loading tray, a hook material carrier and a hook material linear module. The hook hooks and pulls the material loading tray to the hook material carrier, and the hook material linear module drives the hook material carrier to move to transport the material loading tray.

[0082] In some embodiments, combined Figure 1 and Figure 4 As shown, the assembly and transport mechanism 510 includes a plurality of assembly and transport nozzles 511 and an assembly and transport linear module 512. The assembly and transport nozzles 511 are suitable for reciprocating motion under the drive of the assembly and transport linear module 512 and pass through the angle transfer mechanism 300. The assembly and transport linear module 512 is set at an angle to the assembly loading platform linear module 522.

[0083] In this embodiment, the number and position of assembly and handling nozzles 511 are adapted to the positioning platform 310. Assembly and handling linear modules 512 drive assembly and handling nozzles 511 to the positioning platform 310, where they pick up multiple materials at once and transport them to the assembly loading platform 521, where they are installed one by one into the lens barrel. Using multiple assembly and handling nozzles 511 to handle multiple materials simultaneously effectively improves lens production efficiency, and vacuum handling prevents damage to the material surfaces.

[0084] In some embodiments, combined Figures 7 to 9 As shown, the suction direction of the material picking nozzle 430 is set along the radial direction of the material picking turntable 410; the material picking mechanism 400 also includes a material picking camera 440, which is set on the side of the material picking turntable 410 away from the material picking moving module 420 and is parallel to the disk surface of the material picking turntable 410.

[0085] In this embodiment, along the Z direction shown in the figure, the material to be sucked by the material suction nozzle 430 at the bottom of the material picking turntable 410 is sucked. After the sucking is completed, the material picking turntable 410 rotates, and the material rotates to the side of the material picking turntable 410 together with the material picking suction nozzle 430. Compared with the traditional setting form of the material picking turntable 410 in which the disk surface is parallel to the horizontal plane, the present application can make full use of the lateral space of the material picking turntable 410 and effectively avoid interference between the sucked material and the material to be sucked.

[0086] Furthermore, the material picking camera 440 is used to obtain the position of the material to be sucked, ensuring that the material picking nozzle 430 can accurately pick up the material. The material picking camera 440 is arranged on the side of the material picking turntable 410 away from the moving module, which is conducive to reducing the distance between the detection field of view of the material picking camera 440 and the material picking nozzle 430, thereby improving positioning accuracy; the material picking camera 440 is parallel to the disk surface of the material picking turntable 410, that is, parallel to the material picking nozzle 430 of the material to be sucked, thereby avoiding angular errors in the Z direction.

[0087] Of course, in other embodiments, the suction direction of the material picking nozzle 430 can also be set to be parallel to the rotation axis of the material picking turntable 410; the material picking camera 440 can also be set to be tilted so that it can detect the material to be sucked.

[0088] In some embodiments, combined Figures 7 to 10 As shown, the reclaiming turntable 410 is provided with a hollow wiring groove 411, which is arranged coaxially with the rotation axis of the reclaiming turntable 410. The reclaiming suction nozzle 430 is connected to the external vacuum source via a vacuum air pipe 412, which passes through the hollow wiring groove 411. The hollow wiring groove 411 is coaxial with the rotation axis, and the length of the vacuum air pipe 412 from the reclaiming suction nozzle 430 to the center of the reclaiming turntable 410 varies little, eliminating the risk of fatigue fracture caused by repeated twisting of traditional rotary joints or external hoses. In addition, the vacuum air pipe 412 is arranged in the hollow wiring groove 411 to avoid exposure, effectively extending the service life of the vacuum air pipe.

[0089] In some embodiments, combined Figure 10 As shown, the vacuum air pipe 412 includes multiple vacuum sub-pipes 4121, each corresponding to a material extraction nozzle 430. Each vacuum sub-pipe 4121 is equipped with an independent switch. Each extraction nozzle 430 can be opened and closed independently, enabling independent suction and discharge of multiple materials. In the event of a single branch failure, it can be independently closed, reducing system energy consumption and maintenance costs.

[0090] In some embodiments, combined Figures 7 to 10 As shown, the material picking mechanism 400 also includes a servo motor 450 and a hollow reducer 460. The rotation axis of the servo motor 450 is parallel to the rotation axis of the hollow reducer 460. The servo motor 450 and the material picking turntable 410 are power coupled through the hollow reducer 460. The hollow structure of the hollow reducer 460 is connected to the hollow wiring groove 411.

[0091] In this embodiment, the high transmission efficiency of the hollow reducer 460, combined with the angle control accuracy of the servo motor 450, ensures that the rotation positioning error of the material-retrieving turntable 410 is small while supporting high-speed start and stop; the hollow structure of the hollow reducer 460 is directly connected to the hollow wiring groove 411, and the vacuum air pipe 412 is built-in to eliminate the risk of external pipeline entanglement; the servo motor 450 and the hollow reducer 460 can be quickly separated, shortening maintenance time, and the hollow structure reserves space for sensor / power line expansion to support future intelligent upgrades.

[0092] In other embodiments, the rotation mode of the material retrieving turntable 410 can also be a motor-driven gear set, a motor direct connection, etc.

[0093] In some embodiments, combined Figure 10As shown, the material picking turntable 410 is provided with a plurality of suction nozzle mounting positions; the material picking suction nozzle 430 includes a suction nozzle portion 431 and a mounting portion 432, the mounting portion 432 is detachably connected to the suction nozzle mounting position, the suction nozzle portion 431 can absorb materials, and different material picking suction nozzles 430 have the same mounting portion 432 and different suction nozzle portions 431.

[0094] In this embodiment, the material picking suction nozzle 430 is provided with different suction nozzle parts 431 for adsorbing different types of materials, and the mounting part 432 of each material picking suction nozzle 430 is also provided to be the same, so that any material picking suction nozzle 430 on the material picking turntable 410 can be quickly replaced, which greatly improves the timeliness of the material picking mechanism 400 for transporting materials of different types of lenses.

[0095] In this embodiment, the mounting portion 432 of the material picking nozzle 430 includes a plate portion and a shaft portion (not shown in the figure), the plate portion is provided with a plurality of screw through holes, and the corresponding plate portion of the material picking turntable 410 is provided with a shaft hole that is plugged into the shaft portion and a plurality of screw connection holes corresponding to the screw through holes.

[0096] In other embodiments, the detachable connection between the material picking nozzle 430 and the material picking turntable 410 may also be a magnetic connection, a snap connection, etc.

[0097] In some embodiments, combined Figure 7 As shown, the material picking moving module 420 includes a plurality of material picking linear modules, the movable parts and fixed parts of adjacent material picking linear modules are connected in sequence, and the extension directions of different material picking linear modules are set at an angle.

[0098] In this embodiment, the reclaiming movement module 420 is configured with three reclaiming linear modules. The reclaiming movement module 420 includes a first linear module 422 (Y-axis), a second linear module 423 (X-axis), and a third linear module 424 (Z-axis). The third linear module 424 is connected to the reclaiming turntable 410 to enable three-dimensional movement of the reclaiming turntable 410. Of course, the number and arrangement of the reclaiming linear modules can be selectively adjusted based on actual handling requirements. For example, if there is no need for Y-axis movement, only the second linear module 423 and the third linear module 424 can be provided.

[0099] In this embodiment, the material picking linear module is a linear slide module, the movable part is the slide, and the fixed part is the slide track; of course, the linear module can also be a screw module (the movable part is the screw nut, and the fixed part is the screw), a cylinder, etc.

[0100] In other embodiments, the material picking and moving module 420 may also be in the form of a robotic arm, a combination of a robotic arm and several linear modules, etc.

[0101] In some embodiments, combined Figure 7As shown, the material picking mechanism 400 includes two material picking turntables 410, and the material picking moving module 420 includes a first linear module 422 and two second linear modules 423. The material picking turntables 410 correspond one to one with the second linear modules 423, and the material picking turntables 410 are connected to the movable part of the first linear module 422 through the second linear module 423; the first linear module 422 is a double-motor linear module.

[0102] In this embodiment, the two material picking turntables 410 are independently driven to move by a double-motor linear module, which effectively reduces the structural volume of the material picking moving module 420 required to drive the two material picking turntables 410 to move, and expands the number of material picking turntables 410 in a single material picking mechanism 400. Without changing the original structure of the material picking turntable 410, the number of materials that can be transported by the material picking mechanism 400 at a single time is increased.
