[0027] In one aspect, as Figure 1 and Figure 2As shown, an assembly cross-sectional view and a partial cross-sectional view of the suction assembly 10 are provided for ease of understanding. Figure 1 and Figure 2 The present invention provides a material suction assembly 10, comprising: a suction nozzle 110 and a suction rod 120, wherein the suction rod 120 is sleeved on the top of the suction nozzle 110; the suction nozzle 110 includes a pin 111 and an external thread portion 112, the pin 111 being located above the external thread portion 112, and the diameter of the pin 111 being smaller than that of the external thread portion 112; the suction rod 120 includes a pin hole 121 and an internal thread portion 122, the pin hole 121 being located above the internal thread portion 122, and the diameter of the pin hole 121 being smaller than that of the internal thread portion 122; the pin 111 is inserted into the pin hole 121 for concentric positioning of the suction nozzle 110 and the suction rod 120; the external thread portion 112 and the internal thread portion 122 are screwed together for fixed connection of the suction nozzle 110 and the suction rod 120. The suction nozzle 110 and the suction rod 120 are connected by an external thread 112 and an internal thread 122 to ensure a stable connection. A pin 111 is set to cooperate with a pin hole 121 to ensure the concentricity of the two and improve the assembly accuracy of the suction nozzle 110 and the suction rod 120. Furthermore, the pin 111 is located above the external thread 112 and the pin hole 121 is located above the internal thread 122, making full use of the positions of the suction nozzle 110 and the suction rod 120 to meet the requirements of miniaturization design.

[0028] In one embodiment, the suction assembly 10 further includes a sealing ring 130, which is disposed at the connection between the suction nozzle 110 and the suction rod 120. The sealing ring 130 at the connection between the suction nozzle 110 and the suction rod 120 ensures the airtightness of the suction assembly 10 and improves the stability of material handling by the suction assembly 10.

[0029] More preferably, the diameter difference between the pin 111 and the external thread 112 is 1mm-2mm. This diameter difference between the pin 111 and the external thread 112 facilitates the assembly of the suction nozzle 110 onto the suction rod 120.

[0030] On the other hand, such as Figure 3 and Figure 4 As shown, this utility model also provides a feeding device, including: a bearing 20, a mounting base 30, a driving component 40, and the aforementioned suction assembly 10. The suction assembly 10 is rotatably connected to the mounting base 30 via the bearing 20. The driving component 40 is mounted on the mounting base 30 and connected to the suction assembly 10, and is used to drive the suction assembly 10 to rotate relative to the mounting base 30. The suction assembly 10 is mounted to the mounting base 30 via the bearing 20 and is driven to rotate by the driving component 40, facilitating the adjustment of the material position below the suction nozzle 110 according to user needs, thus improving the application scenarios of the feeding device.

[0031] It should be noted that the suction assembly 10 is rotatably connected to the mounting base plate 30 through the bearing 20, so that the suction assembly 10 can rotate relative to the mounting base plate 30, and the central axis of the suction rod 120 will not be deflected from the mounting base plate 30 when the suction rod 120 rotates.

Considering that the material has directionality, the suction nozzle 110 needs to rotate the suction assembly 10 through the driving member 40 after adsorbing the material to adjust the direction of the material, and in order to ensure that the adjustment of the direction of the material is accurate enough, the inductive sheet 50 cooperates with the inductor 60 to realize accurate positioning of the rotation of the material, thereby improving the accuracy of the feeding device in taking and placing the material.

[0033] Further preferably, the feeding device further comprises a rotary joint 70, the rotary joint 70 is arranged at the top of the suction rod 120, and the suction rod 120 can rotate around the rotary joint 70. Considering that the feeding device needs to be connected with the air pipe of the external vacuum device, the rotary joint 70 is convenient for connecting the suction assembly 10 with the air pipe of the external vacuum device. And the suction rod 120 can rotate around the rotary joint 70, so as to avoid that the air pipe of the external vacuum device rotates together with the suction rod 120, thereby preventing the air pipe from winding and affecting the taking and placing of the material.

[0034] Further preferably, the feeding device further comprises a locking nut 80, the locking nut 80 is arranged on the bearing 20 and is threadedly connected to the outer side wall of the suction rod 120, and is used for abutting the bearing 20 against the mounting base plate 30.

[0035] Further preferably, the driving member 40 comprises a first synchronous wheel 410, a synchronous belt 420, a second synchronous wheel 430 and a stepping motor 440, the first synchronous wheel 410 is connected to the outer side wall of the suction rod 120, the second synchronous wheel 430 is connected to the stepping motor 440, and the second synchronous wheel 430 drives the first synchronous wheel 410 to rotate synchronously through the synchronous belt 420.
