[0065] As an embodiment, the loading mechanism 20 includes a vibration disk 21 and N joint flow channels 22, the vibration disk 21 has N discharge ends, the material transfer mechanism 30 has N receiving ends, the first ends of the N joint flow channels 22 are connected one by one with the discharge end of the vibration disk 21, the second ends of the N joint flow channels 22 correspond one by one with the receiving end of the material transfer mechanism 30, and the joint flow channels 22 are configured to sequentially transport the joints received from the discharge end of the vibration disk 21 to the corresponding receiving ends.

[0066] Optionally, a sensor 23 is provided on each joint flow channel 22 near its second end, and the sensor 23 is configured to detect whether the corresponding joint flow channel 22 is short of material.

[0067] Through the cooperation of the vibration plate 21 and the N joint flow channels 22, automatic loading of the joints is achieved, providing a highly efficient, stable and compact loading mechanism 20.

Since the joint flow channel 22 and the material receiving trough have no limit on the horizontal section of the joint, the joint 15 may be in any direction when it moves along the joint flow channel 22 to the material receiving trough. After the joint enters the material receiving trough and is moved to the material taking station, the horizontal section of the joint may also be in any direction. In order to avoid the clamping assembly 43 from interfering with the joint when clamping the joint 15 at the material taking station, the horizontal section 150 of the joint 15 needs to be arranged in advance to be in the same direction;

[0075] Optionally, the limiting member 314 is a cylindrical rod.

[0076] By setting the two limit members 341, when the joint 15 passes through the two limit members 341, the horizontal section 150 of the joint 15 is automatically arranged to extend along the first direction; providing a simple structure, ingenious design and low cost arrangement component 34.
