The first driving member 242 is installed on the first vertical frame 241 and is used for driving the first rotating shaft 241a to rotate, thereby driving the finger cylinder 245 to reciprocate along the arc-shaped guiding groove 241b, so as to transfer the pen tip housing from the second end of the pen tip housing conveying track 220 into the pen tip housing placement groove 111, with stable movement. With the above structure, a driving source (the first driving member 242) drives the finger cylinder 245 to reciprocate in the X direction and the Y direction, so that the finger cylinder 245 can transfer the pen tip housings at the second end of the pen tip housing conveying track 220 into the pen tip housing placement groove 111, saving the driving source (two driving sources are required in the existing case), and reducing the driving source cost.

The finger cylinder 245 can move relative to the first upright frame 241 in the X-direction and Y-direction through the X-direction linear guide 246a and the Y-direction linear guide 246b, with stable movement and high movement accuracy.

[0064] In another embodiment of the present invention, referring to Figure 2 , Figure 4 , Figure 6 and Figure 8 , the hair head feeding mechanism 300 includes a hair head conveying track 310, a hair head linear vibrator 320, a hair head transfer assembly 330, and a hair head feeding assembly 340.

The hair head transfer assembly 330 is installed between the first rotating disk 110 and the hair head conveying track 310, and the hair head transfer assembly 330 is used to feed the hair heads on the hair head conveying track 310 into the pen tip housing. The hair head linear vibrator 320 vibrates to move the hair heads in the hair head conveying track 310 to one side of the hair head transfer assembly 330, so that the hair head transfer assembly 330 can feed the hair heads on the hair head conveying track 310 into the pen tip housing.

[0066] Furthermore, referring to Figure 2 , Figure 4 , Figure 6 and Figure 8, the hair tip feeding assembly 340 includes a moving platform 341, a second vertical frame 342, a first Z-direction transfer assembly 343, a second driving member 344, and a hair tip suction bar 345. The second vertical frame 342 and the moving platform 341 are both installed on the frame 100. The moving platform 341 is used for placing a hair tip tray (not shown in the figure). The first Z-direction transfer assembly 343 is installed on the second vertical frame 342. A pair of mounting seats 346 are symmetrically installed on the first Z-direction transfer assembly 343.

By driving the hair tip suction bar 345 to move and rotate respectively through the first Z-direction transfer assembly 343 and the second driving member 344, the plurality of hair tip adsorption grooves 345a are brought close to the hair tips on the hair tip tray. The air pump provides negative pressure to adsorb the hair tips into the hair tip adsorption grooves 345a, so that the plurality of hair tip adsorption grooves 345a add the hair tips on the hair tip tray to the hair tip conveying track 310. The air pump provides positive pressure, and the hair tips fall from the hair tip adsorption grooves 345a onto the hair tip conveying track 310, and the structure is reliable. If the hair tips are fed by a vibrating disk, the vibrating feeding method of the vibrating disk will disperse the hairs of the hair tips, making the hair tips unqualified. Therefore, by using the feeding method of the above-mentioned hair tip feeding assembly 340 for the hair tips, the hairs of the hair tips can be kept intact and will not disperse, ensuring the quality of the eyeliner pen.
