In existing technology, a suction nozzle structure includes an outer sleeve, a shaft, and a suction nozzle mounted on the shaft, with the shaft slidably installed within the outer sleeve. During the movement of the shaft within the outer sleeve, misalignment can easily occur between the shaft and the sleeve, affecting the positional accuracy of the suction nozzle and consequently, the accuracy with which the nozzle picks up the workpiece. Summary of the Invention

[0005] The inner wall of the sleeve assembly is provided with an internal spline, and the outer wall of the shaft is provided with an external spline that is adapted to the internal spline. The shaft is slidably installed in the through hole through the meshing internal spline and the external spline.
[0006] Optionally, the nozzle assembly includes a nozzle seat and a plurality of nozzle bodies mounted on the nozzle seat, wherein one end of the nozzle seat opposite to the nozzle bodies is mounted on the shaft.
[0007] The suction hole includes a first channel disposed on the nozzle seat and a second channel disposed on the nozzle body, and the inner hole is connected to all the second channels through the first channel.
[0008] Optionally, the splined nozzle structure further includes an elastic element, the opposite ends of which are respectively connected to the nozzle assembly and the sleeve assembly.
[0009] Optionally, the sleeve assembly includes an inner sleeve and an outer flange sleeve fitted on the inner sleeve, wherein the through hole and the internal spline are both provided on the inner sleeve.
[0010] Another embodiment of the present invention provides a transfer device, including a transplanting drive mechanism, a support base with a plug hole, and the above-mentioned spline suction nozzle structure; the support base is mounted on the transplanting drive mechanism, and the sleeve assembly is mounted in the plug hole.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.
[0023] like Figures 1 to 3 As shown, one embodiment of this utility model provides a splined suction nozzle structure 1, including a sleeve assembly 11 with a through hole 111, a shaft 12 with an inner hole 121, and a suction nozzle assembly 13 with a suction hole 131; the suction nozzle assembly 13 is mounted on the shaft 12, and the inner hole 121 communicates with the suction hole 131; the inner wall of the sleeve assembly 11 is provided with an internal spline 112, and the outer wall of the shaft 12 is provided with an external spline 122 adapted to the internal spline 112; the shaft 12 is slidably mounted in the through hole 111 by the intermeshing internal spline 112 and the external spline 122. It can be understood that the internal spline 112 is disposed on the inner wall of the through hole 111; the internal spline 112 is an elongated internal tooth, and the external spline 122 is an elongated external tooth.
[0024] In this invention, the suction nozzle assembly 13 is mounted on the shaft 12, and the inner hole 121 communicates with the suction hole 131. The inner wall of the sleeve assembly 11 is provided with an internal spline 112, and the outer wall of the shaft 12 is provided with an external spline 122 adapted to the internal spline 112. The shaft 12 is slidably mounted in the through hole 111 via the meshing internal spline 112 and external spline 122. During the movement of the suction nozzle assembly 13 driven by the shaft 12, the shaft 12 slides in the through hole 111, and the internal spline 112 and external spline 122 remain engaged. The meshing of the internal spline 112 and external spline 122 prevents the shaft 12 and the sleeve assembly 11 from shifting, ensuring the accuracy of the spline suction nozzle structure 1. Furthermore, the sleeve and the suction nozzle assembly 13 will not wobble, ensuring the stability of the spline suction nozzle structure 1 in picking up the workpiece.
[0025] In one embodiment, such as Figures 1 to 3 As shown, the suction nozzle assembly 13 includes a suction nozzle seat 132 and a plurality of suction nozzle bodies 133 mounted on the suction nozzle seat 132. One end of the suction nozzle seat 132 opposite to the suction nozzle bodies 133 is mounted on the shaft 12. The suction hole 131 includes a first channel provided on the suction nozzle seat 132 and a second channel provided on the suction nozzle bodies 133. The inner hole 121 connects all the second channels through the first channel. Understandably, the number of suction nozzle bodies 133 can be determined according to actual needs, and the suction nozzle seat 132 is a square block. In this embodiment, the design of multiple suction nozzle bodies 133 ensures that even if the workpiece has holes, grooves, or other structures, there are corresponding suction nozzle bodies 133 to adsorb the workpiece, further improving the stability of the spline suction nozzle structure 1 in adsorbing the workpiece.
[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the splined suction nozzle structure 1 also includes an elastic element 14, with its opposite ends connected to the suction nozzle assembly 13 and the sleeve assembly 11, respectively. Understandably, the elastic element 14 includes, but is not limited to, springs, etc., and is sleeved between the shaft 12 and the suction nozzle seat 132. Specifically, during the process of the shaft 12 driving the suction nozzle body 133 to adsorb the workpiece, the suction nozzle body 133 will move towards the sleeve assembly 11 and compress the elastic element 14, ensuring flexible contact between the suction nozzle body 133 and the workpiece, and preventing damage to the workpiece during the suction process.
[0027] In one embodiment, such as Figures 1 to 3As shown, the sleeve assembly 11 includes an inner sleeve 113 and an outer flange 114 fitted onto the inner sleeve 113. The through hole 111 and the inner spline 112 are both located on the inner sleeve 113. Understandably, the outer flange 114 has an annular flange extending outwards, allowing it to be mounted on an outer component. In this embodiment, the design of the inner sleeve 113 and the outer flange 114 facilitates the assembly and disassembly of the spline suction nozzle structure 1.
[0028] like Figure 4 As shown, another embodiment of this utility model also provides a transfer device, including a transfer drive mechanism 2, a support base 3 with a insertion hole (not shown in the figure), and the aforementioned spline suction nozzle structure 1; the support base 3 is mounted on the transfer drive mechanism 2, and the sleeve assembly 11 is mounted in the insertion hole. It can be understood that the transfer drive mechanism 2 can drive the spline suction nozzle structure 1 to move, thereby realizing the function of transporting workpieces.
[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the transplanting drive mechanism 2 includes an X-axis drive assembly 21, a Y-axis drive assembly 22, a Z-axis drive assembly 23, and a Z-axis rotary drive component 24. The Y-axis drive assembly 22 is mounted on the X-axis drive assembly 21, the Z-axis drive assembly 23 is mounted on the Y-axis drive assembly 22, and the Z-axis rotary drive component 24 is mounted on the Z-axis drive assembly 23 and connected to the sleeve assembly 11. It can be understood that the sleeve assembly 11 is rotatably mounted in the insertion hole. The X-axis drive assembly 21, the Y-axis drive assembly 22, and the Z-axis drive assembly 23 include, but are not limited to, pneumatic cylinders, hydraulic cylinders, and lead screw and nut mechanisms.
[0030] Specifically, the X-axis drive component 21 can drive the Y-axis drive component 22 to move along the X-axis, the Y-axis drive component 22 can drive the Z-axis drive component 23 to move along the Y-axis, the Z-axis drive component 23 can drive the Z-axis rotation drive component 24 to move along the Z-axis, and the Z-axis rotation drive component 24 can drive the spline suction nozzle structure 1 to rotate along the Z-axis. In this embodiment, the transplanting drive mechanism 2 can drive the spline suction nozzle structure 1 to move along the X, Y, and Z axes, and can also drive the spline suction nozzle structure 1 to rotate around the Z-axis, improving the applicability and versatility of the transfer device.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
