[0022] Please refer to Figure 1 and Figure 2 As shown, in one aspect, this utility model embodiment provides a suction nozzle module, including a frame 100, a suction nozzle 200, and a centering mechanism 300; the suction nozzle 200 is slidably connected to the frame 100 along a first direction; the centering mechanism 300 is connected to the frame 100 and is disposed at the end of the movement path of the suction nozzle 200 along the first direction. The centering mechanism 300 includes a driving member 320 and a plurality of clamping plates 310 arranged around the axis of the suction nozzle 200. The plurality of clamping plates 310 surround and form a positioning groove 311 for positioning and adsorbing objects. The driving member 320 drives the clamping plates 310 to move radially along the suction nozzle 200 to switch between an avoidance state and a positioning state. In the avoidance state, the plurality of clamping plates 310 move radially away from the suction nozzle 200, and the suction nozzle 200 can move along the first direction and pass through the positioning groove 311. In the positioning state, the plurality of clamping plates 310 move radially closer to the suction nozzle 200 to clamp and position the adsorbed object.

[0023] According to the suction module of this utility model embodiment, when the suction module needs to transfer the adsorption object (such as a lens) between fixtures, the clamping plate 310 is initially in an avoidance state. Figure 2 As shown), the suction nozzle module moves to the side of the clamping plate 310 of the centering mechanism 300, and the driving component 320 drives the clamping plate 310 to move and clamp the object to be absorbed. The clamping plate 310 switches to the positioning state (as shown). Figure 1 As shown in the figure, the axis of the adsorbed object is aligned with the axis of the suction nozzle 200. The suction nozzle 200 moves down along the first direction (shown in the figure - Z direction) and adsorbs the adsorbed object that is clamped and positioned. Then the clamping plate 310 is opened to the avoidance state. The suction nozzle 200 drives the adsorbed object to move below the clamping plate 310 and transfer it to the downstream fixture. The adsorption is released to realize the transfer of the adsorbed object.

[0024] According to the embodiment of the present invention, the suction module clamps and positions the adsorption object through the clamping plate 310 of the centering mechanism 300. During each transport, the axis of the adsorption object is aligned with the axis of the suction nozzle 200, which ensures the accuracy of the position of the adsorption object during transport. Furthermore, there is no need to set up position detection equipment such as a vision camera, which greatly reduces the production and maintenance costs of the suction module.

[0025] In this embodiment, the drive component 320 is a cylinder, but it can also be a lead screw module, a slide module, a worm gear mechanism, etc.

[0026] In some embodiments, combined with Figure 1 and Figure 2 As shown, the centering mechanism 300 includes two clamping plates 310, which extend along a second direction (X direction in the figure). The second direction is perpendicular to the first direction. The clamping plates 310 are provided with a plurality of positioning notches 3111 arranged sequentially along the second direction. The positioning notches 3111 of the two clamping plates 310 correspond one to one, and the opposing positioning notches 3111 form a positioning groove 311. The suction nozzle module includes a plurality of suction nozzles 200, and the position and number of suction nozzles 200 match the positioning notches 3111.

[0027] In this embodiment, by setting two clamping plates 310, multiple positioning slots 311 can be set in the extending direction of the clamping plates 310 for positioning different adsorption objects, so as to realize that the driving component 320 can complete the clamping and positioning of multiple adsorption objects in one drive, which greatly improves the positioning efficiency and adsorption and transportation efficiency of the suction nozzle module.

[0028] In other embodiments, the number of clamping plates 310 can be adjusted based on actual needs. For example, a suction nozzle 200 can be provided, and three centrally symmetrical clamping plates 310 can be provided below the suction nozzle 200 to clamp, position, and adsorb the object.

[0029] In some embodiments, combined with Figure 1 and Figure 2 As shown, the centering mechanism 300 also includes a linkage 330, which connects the clamping plate 310 and the driving member 320. One of the linkage 330 and the clamping plate 310 is provided with a sliding part 332, and the other is provided with a sliding groove 312 that slides with the sliding part 332. Along the direction from the nozzle 200 to the centering mechanism 300, the sliding groove 312 gradually extends away from the axis of the nozzle 200.

[0030] In this embodiment, the driving component 320 drives the linkage component 330 to move along the -Z direction shown in the figure. The sliding part 332 and the sliding groove 312 cooperate to convert the movement of the linkage component 330 into the movement of the clamping plate 310 along the Y direction shown in the figure, so that the two clamping plates 310 move in opposite directions and switch to the positioning state to clamp and position the adsorbed object. The linkage component 330 moves along the Z direction shown in the figure in the same way. At this time, the two clamping plates 310 move in opposite directions and switch to the avoidance state. The simultaneous opening and closing of the two clamping plates 310 is achieved by the linkage component 330, which improves the repeatability of the clamping plates 310.

[0031] In other embodiments, the linkage 330 can also be in the form of a connecting rod or a worm gear, so as to convert the movement of the movable end of the drive member 320 into the opening and closing motion of the two clamping plates 310.

[0032] In some embodiments, combined with Figure 1 and Figure 2As shown, the linkage 330 includes a moving part 331, which is connected to the drive member 320, and a sliding part 332 is rotatably connected to the moving part 331. The rotatable connection reduces the friction between the sliding part 332 and the groove 312.

[0033] In some embodiments, combined with Figure 1 and Figure 2 As shown, the centering mechanism 300 also includes an elastic element 350, which abuts against the two clamping plates 310. The elastic force of the elastic element 350 ensures that the sliding part 332 and the groove wall of the sliding groove 312 remain in contact during the sliding process, reducing the impact of the fitting gap between the sliding part 332 and the sliding groove 312 on the positioning accuracy of the adsorbed object.

[0034] In this embodiment, the elastic element 350 is a linear spring, but it can also be a silicone pad, rubber pad, etc.

[0035] In some embodiments, combined with Figure 1 and Figure 2 As shown, the nozzle module also includes an auxiliary track 340, which extends along a third direction (Y direction in the diagram). This third direction is perpendicular to the first and second directions. The clamping plate 310 and the frame 100 are slidably connected via the auxiliary track 340. The auxiliary track 340 ensures that the clamping plate 310 can move accurately along the third direction and also bears the weight of the clamping plate 310, reducing the load on the linkage 330 and the drive component 320, and improving the service life of the nozzle module.

[0036] In some embodiments, combined with Figure 1 and Figure 3 As shown, the suction nozzle module includes two driving components 320 and two linkage components 330. One driving component 320 and one linkage component 330 are arranged as a group at the end of the clamping plate 310 along the second direction. When the clamping plate 310 has a large span along the X direction shown in the figure, the combination of driving components 320 and linkage components 330 at both ends of the clamping plate 310 can effectively avoid the clamping plate 310 being subjected to force on one side and improve the stability of the opening and closing movement of the clamping plate 310.

[0037] In some embodiments, combined with Figure 1 and Figure 2 As shown, the clamping plate 310 includes a detachably connected main plate portion 313 and a clamping portion 314. The main plate portion 313 is connected to the drive component 320, and the clamping portion 314 is adapted to form a positioning groove 311. By replacing the clamping portion 314 with different structures, it can be adapted to adsorb objects of different shapes; and the centering mechanism 300 can simultaneously position multiple adsorb objects of different shapes, thereby improving positioning and handling efficiency.

[0038] In some embodiments, combined with Figure 1 and Figure 2As shown, the nozzle module also includes a first linear module 400, through which the nozzle 200 is connected to the frame 100. The first linear module 400 can be a cylinder, a lead screw module, a slide module, etc. In this embodiment, if a cylinder is used, a linear track can be added between the nozzle 200 and the frame 100 to ensure the movement accuracy of the nozzle 200 along the first direction and reduce the load on the piston rod of the cylinder.

[0039] Secondly, this utility model embodiment also provides a lens handling module, including a suction nozzle module as described in the above embodiment and a handling drive assembly, wherein the handling drive assembly is adapted to drive the suction nozzle module to move. The handling drive assembly can be a robotic arm, a combination structure of several linear modules, etc., to achieve the movement of the suction module in three-dimensional space.

[0040] Thirdly, this utility model embodiment also provides a lens assembly device, including a nozzle module or lens handling module as described in the above embodiment.

[0041] 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.
