[0032] In this embodiment, an assembly plate 200 is rotatably arranged on the workbench 100, and each assembly jig 210 is circumferentially distributed on the assembly plate 200. The piston assembly mechanism 300, the pen tip assembly mechanism 400, and the pen tip shell assembly mechanism 500 are sequentially arranged around the assembly plate 200, so that the piston can be sequentially transported into the assembly cavity 211 of the assembly jig 210, and then the pen tip is assembled on the piston in the assembly cavity 211, and finally the pen tip shell is assembled on the piston with the pen tip, and the two positioning blocks 432 of the pen tip assembly mechanism 400 are matched. The first end of the positioning cavity 433 formed between them is aligned with the assembly cavity 211, and the two pneumatic clamps 460 are aligned with the material seat 420 and the second end of the positioning cavity 433, that is, as the assembly plate 200 rotates, the assembly cavity 211 of each assembly fixture 210 is aligned with a pneumatic clamp 460 in turn. When the assembly cavity 211 of an assembly fixture 210 is aligned with the pneumatic clamp 460, the two positioning blocks 432 move in a direction close to each other to form a positioning cavity 433.

Specifically, as the assembly disk 200 rotates, the assembly cavity 211 of each assembly jig 210 is aligned with the second assembly rod 520 in turn. When the assembly cavity 211 of an assembly jig 210 is aligned with the second assembly rod 520, the two limit blocks 532 move in a direction approaching each other to abut against each other to form a limit cavity 533. At this time, one end of the piston with a pen tip in the assembly cavity 211 is located in the first end of the limit cavity 533, and the pen tip shell enters the limit cavity 533 through the second end of the limit cavity 533. By cooperating with the second assembly rod 520 to move in a direction close to the second end of the limit cavity 533, the pen tip shell in the limit cavity 533 can be assembled on the piston with the pen tip, thereby completing the assembly of the pen tip.
