[0023] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, on the one hand, an embodiment of the present invention provides a lens assembly device, including an assembly module 500 and a plurality of feeding modules 10, the feeding modules 10 being suitable for providing a variety of materials for assembling lenses; the assembly module 500 including a plurality of assembly conveying mechanisms 510 and a plurality of assembly loading platform mechanisms 520, the assembly conveying mechanisms 510 corresponding to the feeding modules 10 one by one, the assembly conveying mechanisms 510 connecting the corresponding feeding modules 10 with the plurality of assembly loading platform mechanisms 520; the assembly loading platform mechanism 520 including an assembly loading platform 521 and an assembly loading platform driving assembly 522, the assembly loading platform 521 being suitable for moving under the drive of the assembly loading platform driving assembly 522, the assembly loading platform driving assembly 522 being provided with a plurality of loading stations, the positions of the plurality of loading stations being adapted to the plurality of assembly conveying mechanisms 510.

[0024] According to the lens assembly equipment of the embodiment of the present invention, in order to facilitate the explanation of the specific working method of the lens assembly equipment of the present invention, taking the lens assembly equipment provided with two feeding modules 10, the assembly module 500 provided with two assembly conveying mechanisms 510 and two assembly loading platform mechanisms 520 as an example, the assembly conveying mechanism 510 obtains the material provided by the corresponding feeding module 10, and selectively conveys it to the top of the loading station of one of the assembly loading platform driving components 522, and the assembly loading platform driving component 522 drives the assembly loading platform 521 to move to the loading station to receive the material conveyed by the assembly conveying mechanism 510.

[0025] In this embodiment, based on the selective transport of the assembly transport mechanism 510, the lens assembly equipment has a multi-line independent mode and a collaborative mode.

[0026] Multi-line independent mode (dual-line independent mode in this embodiment): the first feeding module 10, the first assembly and conveying mechanism 510 and the first assembly loading platform mechanism 520 are an operating unit, the second feeding module 10, the second assembly and conveying mechanism 510 and the second assembly loading platform mechanism 520 are an operating unit, and the two operating units operate independently. By modifying the process parameters, the lenses assembled by the first operating unit and the second operating unit are compared. The lens assembly equipment can adjust at least two process parameters at a time, effectively improving the efficiency of adjusting the process parameters of the lens; the first operating unit and the second operating unit can also be set to independently assemble different lenses to improve production efficiency, or, one of the first operating unit and the second operating unit can be used as a debugging line, and the other can be used as an assembly line, and the two do not interfere with each other.

[0027] Collaborative mode: the materials provided by the two feeding modules 10 are different, and the two assembly transport mechanisms 510 transport the materials provided by the corresponding feeding modules 10 and move them to the same assembly loading platform mechanism 520 for assembly.

[0028] Of course, based on actual needs, the number of feeding modules 10 and the number of assembly transport mechanisms 510 and assembly loading platform mechanisms 520 included in the assembly module 500 can be adaptively adjusted.

[0029] It should be noted that in the related art, the lenses that need to be assembled by lens assembly equipment usually have multiple process parameters (such as lens angle, lens spacing, glue type, curing strength, etc.) that need to be debugged. Conventional lens assembly equipment needs to adjust each parameter separately and run the assembly process in its entirety once, which results in slow adjustment of lens process parameters and low lens production efficiency.

[0030] According to the lens assembly equipment of the embodiment of the present invention, by setting up multiple feeding modules 10 to cooperate with multiple assembly loading platform mechanisms 520 and assembly conveying mechanisms 510, the lens assembly equipment has multiple different working modes. It is not only suitable for treating any one of the feeding modules 10, the assembly conveying mechanism 510 and the assembly loading platform mechanism 520 as a lens debugging line or production line, but also allows the lens assembly equipment to simultaneously include multiple lens debugging lines or production lines, so as to achieve the adjustment of multiple process parameters for the same lens to compare and obtain the influence of the process parameter adjustment on the lens assembly quality, and effectively improve the process parameter debugging efficiency of the lens; and, multiple feeding modules 10 can provide different types of materials, and they are transported to the same assembly loading platform mechanism 520 for assembly by their respective corresponding assembly conveying mechanisms 510, which expands the number of materials that can be adapted to the lens in a single assembly loading platform mechanism 520, so as to achieve the lens assembly equipment to adapt to a larger number of materials and types of lenses.

[0031] In this embodiment, the assembly loading platform driving component 522 is a slide linear module. Of course, it can also be a component such as a cylinder, a screw module, a robotic arm, etc. that can realize the movement of the assembly loading platform 521.

[0032] Furthermore, it should be noted that, in order to solve the problem of difficulty in debugging the process parameters of the above-mentioned lenses, although a design concept similar to the present application is proposed in the related art of using multiple assembly and handling mechanisms 510 and multiple assembly loading platform mechanisms 520 to form an independent operating unit, the technical solution generally adopts different handling mechanisms for different materials for the loading and assembly of multiple materials, and each handling mechanism has an independent driving module (mechanical arm, linear module, etc.) and a handling module (gripper or suction nozzle, etc.), resulting in that the space required for the structure of material handling in the overall volume of the existing lens assembly equipment is too large, and the volume of the feeding module 200 is greatly limited when the volume of the lens assembly equipment remains unchanged, resulting in that only a small number of materials can be installed; and when assembling lenses with many types of materials, if the handling mechanisms of the prior art are used, there will be too many handling mechanisms in the lens assembly equipment, and there will be a problem of excessive structural volume of the lens assembly equipment.

[0033] To solve the above problems, in this embodiment, combined with Figure 1 to Figure 2 , Figures 8 to 11As shown, the feeding module 10 includes an angle transfer mechanism 300, a material picking mechanism 400 and a feeding module 200, and the assembly and handling mechanism 510 connects its corresponding angle transfer mechanism 300 with multiple assembly loading platform mechanisms 520; the material picking mechanism 400 connects the feeding module 200 and the angle transfer mechanism 300; the material picking mechanism 400 includes a material picking turntable 410, a material picking moving module 420 and multiple material picking suction 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, multiple material picking suction nozzles 430 are connected to the material picking turntable 410 and are arranged around the rotation axis of the material picking turntable 410, and the material picking suction nozzles 430 at different positions are adapted to one of the multiple materials.

[0034] In this embodiment, by setting a plurality of material taking nozzles 430 on the material taking turntable 410, it is possible to suck a plurality of materials at a time and simultaneously transport them to the angle transfer mechanism 300, effectively reducing the repeated transporting beats of different materials and improving the assembly production efficiency of the lens. Only one material taking moving module 420 is needed to realize the transport of a plurality of materials, improve the integration of the material taking mechanism 400, effectively reduce the occupied volume of the material handling related structure in the lens assembly equipment, and correspondingly increase the occupied volume of the feeding module 200 to expand the number of materials, so as to realize the assembly of lenses with a larger number of materials.

[0035] 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 adaptively adjusted based on the materials required for lens assembly, and the material picking turntable 410 can also be provided with multiple material picking nozzles 430 of the same type for transporting multiple materials of the same type at a time.

[0036] In some embodiments, in combination Figure 3 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 extending along a first direction. The assembly and transport nozzles 511 are suitable for reciprocating along a first direction (the Y direction shown in the figure) under the drive of the assembly and transport linear module 512, and pass through a plurality of loading stations of the assembly loading platform mechanism 520.

[0037] In this embodiment, the assembly and transport linear module 512 drives the assembly and transport nozzle 511 to move to the feeding module 10 to absorb multiple materials at one time, and transport them to the top of the loading station corresponding to the assembly loading platform 521, and install the materials one by one. Using multiple assembly and transport nozzles 511 to transport multiple materials at one time effectively improves the lens production efficiency, and the vacuum adsorption form of transportation will not cause damage to the surface of the material.

[0038] In other embodiments, the assembly and handling mechanism 510 may also be in the form of a clamp, and the driving source of the assembly and handling nozzle 511 may also be a cylinder, a screw module, a robotic arm, etc.

[0039] In one embodiment, in combination Figure 3 and Figure 4 As shown, the assembly loading platform driving component 522 includes an assembly loading platform linear module 523, and the assembly loading platform 521 is suitable for moving along the second direction (X direction in the figure) under the drive of the assembly loading platform linear module 523, and the second direction is set at an angle with the first direction.

[0040] In other embodiments, a cylinder, a screw module, a robotic arm, or the like may be used to drive the loading platform 521 to move.

[0041] In some embodiments, in combination Figures 1 to 4 , Figure 8 As shown, the angle transfer mechanism 300 includes an angle transfer table 310 and an angle transfer linear module 320. The angle transfer table 310 is suitable for moving under the drive of the angle transfer linear module 320 and connecting the material picking mechanism 400 and the assembly and handling mechanism 510; the angle transfer table 310 includes a plurality of positioning platforms 311 and a first rotating drive component 312. The number and types of the positioning platforms 311 are suitable for a variety of materials. The positioning platforms 311 are suitable for rotating under the drive of the first rotating drive component 312.

[0042] In this embodiment, the material picking mechanism 400 picks up the various materials provided by the feeding module 200 and transports them to the angle transfer mechanism 300 to be received by the positioning platform 311. The materials on the positioning platform 311 are rotated to the set angle under the drive of the first rotating drive member 312. The multiple positioning platforms 311 are driven by the angle transfer linear module 320 to move into the working range of the assembly and transportation mechanism 510. The assembly and transportation mechanism 510 transports the materials in the positioning platform 311 to the assembly loading platform mechanism 520 for assembly. By pre-rotating different materials to the corresponding set angles by the angle transfer mechanism 300, the efficiency of the assembly and transportation mechanism 510 in transporting and placing the materials on the assembly loading platform mechanism 520 for assembly is improved.

[0043] In this embodiment, the angle transfer linear module 320 can be a slide module, a screw module, a cylinder, etc.; the first rotation driving component 312 can include a stepping motor, a driving motor, etc.

[0044] In some embodiments, in combination Figure 1 , Figure 3 and Figure 6As shown, the feeding module 200 includes a material hooking mechanism 210 and a plurality of material cage placement platforms 220. The material cage placement platforms 220 are suitable for placing material cages, and multiple layers of loading trays are arranged in the material cages; the material hooking mechanism 210 includes a material hooking traction platform 211, a material hooking linear module 212 and a material hooking lifting module 213. The extension direction of the material hooking linear module 212 is parallel to the arrangement direction of the material cage placement platforms 220. The material hooking traction platform 211 is suitable for moving under the drive of the material hooking linear module 212 and docking with different material cage placement platforms 220 in turn, and docking with different layers of loading trays under the drive of the material hooking lifting module 213.

[0045] In this embodiment, the hooking material linear module 212 drives the hooking material traction platform 211 to dock with one of the multiple material cages, and the hooking material lifting module 213 drives the hooking material traction platform 211 to dock with the loading tray in the material cage, and hooks the corresponding loading tray to transfer the loading tray to the working range of the material taking mechanism 400 to realize loading. After the material in the loading tray is empty, it is transported back to the material cage by the hooking material mechanism 210. The production efficiency is improved by setting the hooking material mechanism 210 to transport materials in multiple material cages. And one hooking material traction platform 211 is used to load and unload the loading tray of multiple material cages, which effectively reduces the volume of the hooking material mechanism 210.

[0046] In this embodiment, the hooking linear module 212 and the hooking lifting module 213 can both adopt a slide module, a screw module, a cylinder, etc.

[0047] In some embodiments, in combination Figure 1 , Figure 3 and Figure 6 As shown, the feeding module 200 also includes a plurality of tray positioning platforms 230, and the tray positioning platforms 230 correspond one to one with the cage placing platforms 220, and the tray positioning platforms 230 are arranged on the side of the hooking mechanism 210 close to the assembly module 500; the hooking traction platform 211 is suitable for moving and connecting the tray positioning platform 230 and the cage placing platform 220 under the drive of the hooking linear module 212 and the hooking lifting module 213; the hooking traction platform 211 includes a loading tray hook claw 2111, a tray placing platform 2112 and a hook claw driving component 2113, and the loading tray hook claw 2111 can hook the loading tray under the drive of the hook claw driving component 2113, and transfer it between the tray positioning platform 230 and the cage placing platform 220.

[0048] In this embodiment, the hook driving member 2113 on the hook material pulling platform 211 drives the tray hook 2111 to hook the material tray and pull it to the tray placement platform 2112. The hook material linear module 212 and the hook material lifting module 213 drive the tray placement platform 2112 to correspond to the tray positioning platform 230. The hook material pulling platform 211 transfers the material tray to the tray positioning platform 230 for positioning, and the material picking mechanism 400 picks up the material from the material tray located on the tray positioning platform 230. By setting the tray positioning platform 230, the fixed position of the tray positioning platform 230 effectively guarantees the positioning accuracy of the material tray in three-dimensional space, so as to ensure that the material picking mechanism 400 can stably pick up the material from the material tray, and avoid the position error caused by the operation of the hook material linear module 212 and the hook material lifting module 213, which leads to the failure of picking up the material.

[0049] In the present embodiment, ten tray positioning platforms 230 are provided, and correspond one to one with ten cage placing platforms 220. Of course, the number of tray positioning platforms 230 and cage placing platforms 220 can be adaptively adjusted according to actual needs.

[0050] In this embodiment, the hook driving component 2113 is a driving motor and a synchronous belt. Of course, it can also be a structure such as a cylinder, a linear module, etc. that can drive the carrier hook 2111 to move.

[0051] In some embodiments, in combination Figure 2 , Figure 4 and Figure 7 As shown, the assembly module 500 also includes a dispensing mechanism 530, and each assembly loading platform drive component 522 is provided with a dispensing station corresponding to the dispensing mechanism 530; the dispensing mechanism 530 includes a dispensing head component 531 and a dispensing drive component 532, and the dispensing drive component 532 can drive the dispensing head component 531 to move above the dispensing station.

[0052] In this embodiment, during the assembly process of the lens on the assembly loading platform 521, when the lens has a gluing requirement, the assembly loading platform driving component 522 moves the assembly loading platform 521 to the gluing station, and the gluing mechanism 530 glues the components in the lens. After the gluing is completed, based on the subsequent process, the assembly loading platform 521 can be moved to the loading station for loading, or the assembly transport mechanism 510 can move the lens away from the assembly loading platform 521 for unloading.

[0053] In this embodiment, the glue dispensing mechanism 530 is located above the glue dispensing station of the multiple assembly platform driving components 522, so that glue dispensing can be performed on any component in the lens assembly process when glue dispensing is required. This is different from the traditional form of gluing after the lens is completely assembled. It is particularly suitable for lenses in which components installed in the middle need to be glued, and can be adapted to lenses with more different assembly processes.

[0054] In some embodiments, in combination Figure 2 , Figure 4 and Figure 7 The dispensing drive assembly 532 shown includes a dispensing linear module 5321, which is set at an angle to the assembly loading platform mechanism 520; the dispensing head assembly 531 includes a dispensing pressure head 5311, two dispensing cylinder clamps 5312 and an angle adjustment plate 5313, the dispensing cylinder clamps 5312 are connected to the angle adjustment plate 5313 and are located on both sides of the dispensing pressure head 5311, the dispensing cylinder clamps 5312 are set at an angle, and the axis of the dispensing cylinder clamps 5312 intersects with the axis of the dispensing pressure head 5311.

[0055] In this embodiment, the glue dispensing tube fixture 5312 can move on the angle adjustment plate 5313 to adjust the angle between the glue dispensing tube clamped by the glue dispensing tube fixture 5312 and the glue dispensing head 5311. The glue dispensing head 5311 moves and presses against the components in the lens under the drive of the glue dispensing linear module 5321, and the glue dispensing tube dispenses glue on the components.

[0056] In this embodiment, the dispensing linear module 5321 may include multiple linear modules, such as a linear module extending along the X direction as shown in the figure and a linear module extending along the Z direction, wherein the linear module extending in the Z direction is used to drive the dispensing pressure head 5311 to move; the linear module may be a cylinder, a slide module, a screw module, etc.

[0057] In one embodiment, in combination Figure 4 and Figure 5 As shown, the assembly loading platform 521 includes a positioning shaft 5211 and a shaft driving assembly 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 shaft driving assembly 5212 is suitable for driving the positioning shaft 5211 to rotate.

[0058] In this embodiment, the shaft driving assembly 5212 drives the positioning shaft 5211 to drive the lens to rotate, so that the lens rotates relative to the dispensing mechanism 530, and circular dispensing can be achieved.

[0059] The combination of the above two embodiments can realize circle dispensing, interpolation dispensing, extrusion dispensing, etc. of the lens, and effectively adapt to the dispensing process of different lenses.

[0060] In some embodiments, in combination Figure 1 and Fig.12As shown, the lens assembly equipment also includes an assembly machine 620 and multiple feeding machines 610. The assembly machine 620 is suitable for carrying the assembly module 500, and the feeding machine 610 is suitable for carrying the feeding module 10. The assembly machine 620 and the feeding machine 610 are connected by a docking tool. The docking tool includes a first horizontal insert block 611 arranged on the feeding machine 610, a second horizontal insert block 621 arranged on the assembly machine 620 and matched with the first horizontal insert block 611, and a height connection block. The height connection block is provided with a connection surface, and the connection surface simultaneously connects the table top of the assembly machine 620 and the table top of the feeding machine 610.

[0061] In this embodiment, positioning in the XY direction is achieved by the first horizontal insert block 611 and the second horizontal insert block 621, and positioning in the Z direction is achieved by the height connection block, thereby determining the positions of the assembly machine 620 and the feeding machine 610 in three-dimensional space.

[0062] It should be noted that in equipment with multiple machines, since different machines need to work together, the positional relationship of the functional modules on the machines needs to be guaranteed. The usual form of calibration is to uniformly fine-tune the position of each functional module after the multiple machines are assembled to achieve accurate positioning in three-dimensional space. However, this method has the problem of difficulty in debugging due to the large number of functional modules on the machine and the small remaining debugging position.

[0063] In this embodiment, the lens assembly equipment is disassembled into an assembly machine 620 and a plurality of feeding machines 610, and the functional modules on each machine are independently assembled and adjusted in position to ensure that the feeding module 10 and the feeding machine 610, and the assembly machine 620 and the assembly module 500 are debugged synchronously, thereby effectively improving the debugging efficiency of the lens assembly equipment. The debugged assembly machine 620 and the feeding machine 610 are connected by docking tooling to ensure that the relative positions between the two are determined. Therefore, the staff only needs to fine-tune the positional relationship between the assembly machine 620 and the feeding machine 610 to achieve the connection between the feeding module 10 and the assembly module 500 carried by the two, thereby effectively improving the debugging efficiency.

[0064] In some embodiments, in combination Figures 8 to 10 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 arranged 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.

[0065] In this embodiment, along the Z direction as shown in the figure, the material to be sucked by the material suction nozzle 430 at the bottom of the material picking turntable 410, the material picking turntable 410 rotates after the sucking is completed, 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.

[0066] 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 suck 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 beneficial to reducing the distance between the detection field of view of the material picking camera 440 and the material picking nozzle 430, thereby improving the 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.

[0067] 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 as to detect the material to be sucked.

[0068] In some embodiments, in combination Figures 8 to 11 As shown, the retrieving turntable 410 is provided with a hollow wiring groove 411, which is coaxially arranged with the rotation axis of the retrieving turntable 410, and the retrieving suction nozzle 430 is connected with the external vacuum source through a vacuum air pipe 412, and the vacuum air pipe 412 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 retrieving suction nozzle 430 to the center of the retrieving turntable 410 changes little, eliminating the risk of fatigue fracture caused by repeated twisting of traditional rotary joints or external hoses; and the vacuum air pipe 412 is arranged in the hollow wiring groove 411 to avoid exposure, which effectively improves the service life of the vacuum air pipe.

[0069] In some embodiments, in combination Fig.11 As shown, the vacuum air pipe 412 includes a plurality of vacuum sub-air pipes 4121, which correspond one to one with the material taking suction nozzles 430, and each vacuum sub-air pipe 4121 is provided with an independent switch. Each material taking suction nozzle 430 is opened and closed independently, realizing independent suction and release of multiple materials; a single branch fault can be closed independently, reducing system energy consumption and maintenance costs.

[0070] In some embodiments, in combination Figures 8 to 11As 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.

[0071] 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 picking 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 the maintenance time, and the hollow structure reserves space for sensor / power line expansion to support future intelligent upgrades.

[0072] In other embodiments, the material taking turntable 410 may also rotate in the form of a motor driven gear set, a motor direct connection, etc.

[0073] In some embodiments, in combination Fig.11 As shown, the material picking turntable 410 is provided with a plurality of suction nozzle mounting positions; the material picking suction nozzle 430 comprises 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 is capable of sucking materials, and different material picking suction nozzles 430 have the same mounting portion 432 and different suction nozzle portions 431.

[0074] In this embodiment, the material picking suction nozzle 430 is provided with different suction nozzle parts 431 for sucking 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.

[0075] 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 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 holes.

[0076] 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.

[0077] In some embodiments, in combination Figure 8 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 arranged at an angle.

[0078] In this embodiment, taking the material picking moving module 420 provided with three material picking linear modules as an example, the material picking moving module 420 includes a first linear module 422 (Y direction), a second linear module 423 (X direction) and a third linear module 424 (Z direction), wherein the third linear module 424 is connected to the material picking turntable 410 to realize the movement of the material picking turntable 410 in three dimensions. Of course, based on actual handling requirements, the number and splicing form of the material picking linear modules can be selectively set, such as when there is no Y-direction movement requirement, only the second linear module 423 and the third linear module 424 can be set.

[0079] 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.
