If "first," "second," etc., are used in the description, they are only for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0039] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0040] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, in one aspect, this utility model embodiment provides a lens material handling mechanism, a lens assembly equipment, and a lens production line. The lens material handling mechanism includes a support 210, a moving module 220, a material handling turntable 230, and multiple material handling nozzles 240. The moving module 220 is connected to the support 210. The material handling turntable 230 is rotatably connected to the moving module 220 and can move relative to the support 210 under the drive of the moving module 220. Multiple material handling nozzles 240 are connected to the material handling turntable 230 and are arranged around the rotation axis of the material handling turntable 230. The material handling nozzles 240 at different positions are adapted to one of a variety of materials.

[0041] According to the lens material handling mechanism of this utility model embodiment, one of the multiple material handling nozzles 240 picks up a type of material. After the material is picked up, the moving module 220 drives the material handling turntable 230 to move the material handling nozzle 240 above the next type of material. The material handling turntable 230 rotates so that the empty material handling nozzle 240 corresponds to the next type of material and picks it up. The above process is repeated until each type of material is picked up by the material handling turntable 230. The material handling turntable 230, driven by the moving module 220, transports the picked-up material to the downstream station (such as a central positioning platform or a group loading platform).

[0042] According to the lens material handling mechanism of this utility model embodiment, by setting multiple material handling nozzles 240 on the material handling turntable 230, multiple materials can be picked up at one time and transported to the downstream station simultaneously, effectively reducing the cycle time of repeated handling of different materials and improving the assembly production efficiency of lenses. Furthermore, only one moving module 220 is needed to handle multiple materials, improving the integration of the lens material handling mechanism.

[0043] In this embodiment, the material pick-up turntable 230 is connected to ten material pick-up nozzles 240, each corresponding to a different type of material; in other embodiments, the number of material pick-up nozzles 240 connected to the material pick-up turntable 230 can be adjusted based on the material required for lens assembly, and multiple identical material pick-up nozzles 240 can also be connected to the material pick-up turntable 230 for transporting multiple identical materials at once.

[0044] In some embodiments, combined with Figure 3 and Figure 4 As shown, the suction direction of the material pick-up nozzle 240 is arranged radially along the material pick-up turntable 230; the lens picking mechanism also includes a material pick-up camera 250, which is located on the side of the material pick-up turntable 230 away from the moving module 220 and parallel to the surface of the material pick-up turntable 230.

[0045] In this embodiment, along the Z direction shown in the figure, the material-collecting nozzle 240 located at the bottom of the material-collecting turntable 230 is to collect material. After the material is collected, the material-collecting turntable 230 rotates, and the material rotates together with the material-collecting nozzle 240 to the side of the material-collecting turntable 230. Compared with the traditional arrangement where the surface of the material-collecting turntable 230 is parallel to the horizontal plane, this application can make full use of the lateral space of the material-collecting turntable 230 and effectively avoid interference between the collected material and the material to be collected.

[0046] Furthermore, the picking camera 250 is used to obtain the position of the material to be picked up, ensuring that the picking nozzle 240 can accurately pick up the material. The picking camera 250 is located on the side of the picking turntable 230 away from the moving module 220, which helps to reduce the distance between the detection field of view of the picking camera 250 and the picking nozzle 240, thereby improving the positioning accuracy. The picking camera 250 is parallel to the surface of the picking turntable 230, that is, parallel to the picking nozzle 240 of the material to be picked up, avoiding angular errors in the Z direction.

[0047] Of course, in other embodiments, the adsorption direction of the material suction nozzle 240 can be set to be parallel to the rotation axis of the material pick-up turntable 230; the material pick-up camera 250 can also be set at an angle, as long as it can detect the material to be picked up.

[0048] In some embodiments, combined with Figures 1 to 4As shown, the material handling turntable 230 is provided with a hollow cable tray 231, which is coaxially arranged with the rotation axis of the material handling turntable 230. The material handling nozzle 240 is connected to an external vacuum source through a vacuum tube 232, which passes through the hollow cable tray 231. The hollow cable tray 231 is coaxial with the rotation axis, which makes the length of the vacuum tube 232 from the material handling nozzle 240 to the center of the material handling turntable 230 change little, eliminating the risk of fatigue fracture caused by repeated twisting of traditional rotary joints or external hoses; and by arranging the vacuum tube 232 in the hollow cable tray 231 to avoid exposure, the service life of the vacuum tube 232 is effectively improved.

[0049] In some embodiments, combined with Figure 4 As shown, the vacuum pipe 232 includes multiple vacuum sub-pipes 2321, each corresponding to a material suction nozzle 240. Each vacuum sub-pipe 2321 has an independent switch. Each material suction nozzle 240 can be opened and closed independently, enabling independent suction and discharge of various materials; a single branch failure can be independently shut down, reducing system energy consumption and maintenance costs.

[0050] In some embodiments, combined with Figures 1 to 3 As shown, the lens picking mechanism also includes a servo motor 260 and a hollow reducer 270. The rotation axis of the servo motor 260 is parallel to the rotation axis of the hollow reducer 270. The servo motor 260 and the picking turntable 230 are poweredly coupled through the hollow reducer 270. The hollow structure of the hollow reducer 270 is connected to the hollow cable tray 231.

[0051] In this embodiment, the high transmission efficiency of the hollow reducer, combined with the angle control precision of the servo motor, ensures that the rotational positioning error of the material pick-up turntable 230 is small while supporting high-speed start-stop. The hollow structure of the hollow reducer 270 is directly connected to the hollow wiring trough 231, and the vacuum pipe 232 runs through it, eliminating the risk of external pipeline entanglement. The servo motor 260 and the hollow reducer 270 can be quickly separated, reducing maintenance time. The hollow structure also provides space for sensor / power line expansion, supporting future intelligent upgrades.

[0052] In other embodiments, the rotation of the material handling turntable 230 can also be in the form of motor-driven gear set, motor direct connection, etc.

[0053] In some embodiments, combined with Figure 4 As shown, the material handling turntable 230 is provided with multiple suction nozzle mounting positions; the material handling suction nozzle 240 includes a suction nozzle part 241 and a mounting part 242. The mounting part 242 is detachably connected to the suction nozzle mounting position. The suction nozzle part 241 can adsorb materials. Different material handling suction nozzles 240 have the same mounting part 242 but different suction nozzle parts 241.

[0054] In this embodiment, by setting different suction parts 241 for adsorbing different types of materials in the material pick-up nozzles 240, and setting the same mounting part 242 for each type of material pick-up nozzle 240, any material pick-up nozzle 240 on the material pick-up turntable 230 can be quickly replaced, which greatly improves the timeliness of the lens pick-up mechanism for transporting materials of different types of lenses.

[0055] In this embodiment, the mounting part 242 of the material pick-up nozzle 240 includes a plate part and a shaft part (not shown in the figure). The plate part is provided with a plurality of screw through holes, and the material pick-up turntable 230 is provided with a shaft hole that is inserted and matched with the shaft part and a plurality of screw connection holes corresponding to the screw through holes.

[0056] In other embodiments, the detachable connection between the material suction nozzle 240 and the material turntable 230 can also be a magnetic connection, snap-fit, etc.

[0057] In some embodiments, combined with Figure 1 As shown, the mobile module 220 includes multiple linear modules, with the movable and fixed parts of adjacent linear modules connected in sequence, and the extension directions of different linear modules are set at an angle.

[0058] In this embodiment, taking the mobile module 220 as an example, it includes three linear modules: a first linear module 222 (X-axis), a second linear module 223 (Y-axis), and a third linear module 224 (Z-axis). The first linear module 222 is connected to the support 210, and the third linear module 224 is connected to the material handling turntable 230 to enable the material handling turntable 230 to move in three dimensions. Of course, based on actual handling requirements, the number and splicing form of the linear modules can be selectively set. For example, if there is no requirement for Y-axis movement, only the first linear module 222 and the third linear module 224 can be set.

[0059] In this embodiment, the linear module is a linear slide module, the movable part is a slide, and the fixed part is a slide rail; of course, the linear module can also be a lead screw module (the movable part is a lead screw nut, and the fixed part is a lead screw), a cylinder, etc., to drive the material pick-up turntable 230 to move relative to the bracket 210.

[0060] In other embodiments, the mobile module 220 may also be in the form of a robotic arm, a combination of a robotic arm and several linear modules, etc.

[0061] In some embodiments, the lens feeding mechanism includes two feeding turntables 230, and the moving module 220 includes a first linear module 222 and two second linear modules 223. The fixed part of the first linear module 222 is connected to the bracket 210. The feeding turntables 230 and the second linear modules 223 correspond one-to-one, and the feeding turntables 230 are connected to the movable part of the first linear module 222 through the second linear modules 223. The first linear module 222 is a double-moving linear module.

[0062] In this embodiment, the two material handling turntables 230 are driven independently by the dual-actuator linear module, which effectively reduces the structural volume of the moving module 220 required to drive the two material handling turntables 230 and expands the number of material handling turntables 230 in a single lens material handling mechanism. Without changing the original structure of the material handling turntables 230, the amount of material that the lens material handling mechanism can handle in a single operation is increased.

[0063] Secondly, this utility model provides a lens assembly device, including a lens feeding mechanism as described in the above embodiments.

[0064] Thirdly, this utility model embodiment also provides a lens production line, including a lens feeding mechanism or lens assembly equipment as described in the above embodiments.

[0065] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
