[0039] In actual application, since the first rotating member and the pen holder are screwed together in a clockwise direction, and the second rotating member and the first rotating member are screwed together in a counterclockwise direction, in this embodiment, the clockwise rotation direction of the first rotating member is the positive rotation, and the counterclockwise rotation direction of the first rotating member is the reverse rotation. When the pen holder transfer mechanism 1 transfers the pen holder to the first assembly mechanism 2, the first rotating head 22 drives the first rotating member to rotate in the positive direction, thereby tightening the first rotating member to one end of the pen holder; when the pen holder equipped with the first rotating member is transferred to the second assembly structure, the second rotating member is pushed into the pen holder by the first push rod 311 and supported, and the second rotating head 35 drives the first rotating member to rotate in the reverse direction, thereby achieving the screw connection between the first rotating member and the second rotating member; when the pen holder equipped with the first rotating member and the second rotating member is transferred to the first rotating mechanism 61, the fourth push rod 611 extends into the pen holder and pushes the second rotating member to the third assembly structure. The third rotating head 613 is pressed in the direction of the rotating head 613, at which time the third rotating head 613 is engaged with the first rotating member, and the first rotating head rotation driving device 614 and the third rotating head 613 rotate in the opposite direction, so that the second rotating member can be completely screwed into the first rotating member; then, when the pen holder equipped with the first rotating member and the second rotating member is transferred to the second rotating mechanism 62, the fourth rotating head 621 is engaged with the first rotating member, and the second rotating head rotation driving device 623 drives the fourth rotating head 621 to move in the forward direction, so that the first rotating member can be completely screwed into the pen holder, thereby completing the assembly of the first rotating member, the second rotating member and the pen holder.

The position of the pen cap push rod 43 corresponds to the position of one of the first bearing slots 111 of the pen holder support frame 11.

[0041] In actual application, the pen cap loading device 42 transports the pen cap from the outside to the pen cap supporting platform 41. When the pen holder moving frame 12 moves the pen holder equipped with the first rotating member and the second rotating member to the position corresponding to the pen cap push rod 43, the pen holder holding member 13 descends to hold the pen holder and fix it. The third moving drive device 44 drives the pen cap push rod 43 to move close to the pen holder support frame 11. The pen cap push rod 43 passes through the pen cap supporting platform 41 and pushes the pen cap to one end of the pen holder close to the first rotating member, so that the pen cap is connected to the pen holder, thereby assembling a rotating pen holder.

[0042] Preferably, a plurality of pen cap push rods 43 are arranged in sequence on the third sliding seat 441. In this embodiment, three pen cap push rods 43 are arranged on the third sliding seat 441, and the positions of the three pen cap push rods 43 correspond to the positions of three adjacent first bearing grooves 111 on the pen holder support frame 11. Except for the first pen cap push rod 43 used to push the pen cap onto the pen holder, the other two pen cap push rods 43 are used to re-tighten the pen cap on the pen holder so that the pen cap can be stably sleeved on the pen holder, thereby improving the production quality of the present invention.

[0043] In the present technical solution, the pen cover assembly mechanism 4 also includes a pen cover rotating device 45 for rotating the pen cover assembled on the pen holder, and the pen cover device includes a pen cover rotating head 451 arranged on one side of the pen holder conveying mechanism 1, a third rotating driving device 452 for driving the pen cover rotating head 451 to rotate, and a fourth moving driving device 453 for driving the pen cover rotating head 451 to approach or move away from the pen holder conveying mechanism 1. Specifically, the structure of the pen cover rotating head 451 is the same as that of the first rotating head 22, and the working principle thereof is also the same. The structure of the third rotating driving device 452 is the same as that of the first rotating driving device 23, and the structure of the fourth moving driving device 453 is the same as that of the first moving driving device 24, and the working principle thereof is also the same, which will not be described in detail here.

[0044] In actual application, when the pen holder movable frame 12 transports the assembled rotating pen shaft to the position corresponding to the pen cap rotating head 451, the pen holder holding part 13 descends to hold and fix the rotating pen shaft; the fourth moving drive device 453 drives the pen cap rotating head 451 to move close to the pen holder support frame 11, and the pen cap rotating head 451 is clamped with the pen cap; the third rotating drive device 452 drives the pen cap rotating head 451 to rotate, and the rotating pen cap rotating head 451 drives the pen cap to rotate, so as to ensure that the pen cap can rotate relative to the pen holder. Preferably, the pen set assembly mechanism 4 also includes a defective product pushing mechanism arranged on the side of the third rotating head 613 close to the loading mechanism 5, and the defective product pushing mechanism includes a defective product pushing rod 461 arranged on one side of the pen holder support frame 11, a fourth driving cylinder 462 for driving the defective product pushing rod 461 to approach or move away from the pen holder support frame 11, and a receiving tray 463 arranged on the other side of the pen holder support frame 11, and the third rotating driving device 452 is electrically connected to the fourth driving cylinder 462 via a control circuit board. When the pen cap rotating head 451 cannot drive the pen barrel to rotate, the third rotating drive device 452 will feedback a signal to the control circuit board. When the rotating pen shaft is moved from the position of the third rotating head 613 to the position of the defective push rod 461, the control circuit board sends a command to the fourth driving cylinder 462. The fourth driving cylinder 462 drives the defective push rod 461 to move closer to the pen barrel support frame 11. At this time, the defective push rod 461 pushes the unqualified rotating pen shaft out of the pen barrel support frame 11, causing the rotating pen shaft to fall into the receiving tray 463.

Specifically, the pen holder bearing platform 51 is recessed with a pen holder bearing groove 511 for carrying the rotating pen holder.

[0046] In actual application, after the assembly is completed, the rotating pen shaft is moved to the position corresponding to the pen shaft pushing device 52 under the drive of the pen barrel moving frame 12. The pen shaft pushing device 52 pushes the rotating pen shaft to the pen shaft supporting platform 51. Under the positioning guidance of the pen shaft supporting groove 511 of the pen shaft supporting platform 51, the rotating pen shaft can be stably and accurately pushed into the pen shaft supporting fixture 53. The pen shaft supporting fixture 53 is used to load and collect the rotating pen shaft for the subsequent assembly of the pen core.

Specifically, the pushing driving device includes a fourth sliding seat 522 slidably arranged on one side of the pen barrel support frame 11 and a fifth driving cylinder 523 for driving the fourth sliding seat 522 to move, and the pushing rod 521 is connected to the fourth sliding seat 522. The pressing driving device 525 includes a sixth driving cylinder installed on the fourth sliding seat 522, the cylinder body of the sixth driving cylinder is connected to the fourth sliding seat 522, and the piston rod of the sixth driving cylinder is connected to the pressing block 524. The central axis of the pushing rod 521 is perpendicular to the direction of the pen barrel transferred by the pen barrel transfer mechanism 1.

[0048] In actual application, when the pen holder moving frame 12 transfers the assembled rotating pen holder to the position corresponding to the pushing rod 521, the sixth driving cylinder drives the pressing block 524 to extend toward the direction of the pen holder supporting frame 11, and the pressing block 524 blocks the top of the rotating pen holder carried by the pen holder supporting frame 11; then, the fifth driving cylinder 523 drives the fourth sliding seat 522 to move close to the pen holder supporting frame 11, and the moving fourth sliding seat 522 drives the pushing rod 521 and the pressing block 524 to move synchronously toward the pen holder supporting fixture 53. At this time, the pushing rod 521 will contact the rotating pen holder and push it toward the pen holder supporting fixture 53. The rotating pen holder is pushed onto the pen holder supporting fixture 53 after being positioned and guided by the pen holder supporting groove 511 of the pen holder supporting platform 51, so as to realize the loading and collecting of the rotating pen holder.

[0049] Preferably, the pen holder carrying jig 53 is plate-shaped, and the pen holder carrying jig 53 is vertically arranged with the pen holder carrying platform 51, and the loading mechanism 5 further comprises a jig lifting driving device 54 for driving the pen holder carrying jig 53 to rise and fall. The pen holder carrying jig 53 and the pen holder carrying platform 51 are vertically arranged so that the rotating pen holder can be directly and horizontally pushed onto the pen holder carrying jig 53 without unnecessary conversion actions, thereby saving the loading and receiving time of the rotating pen holder, thereby improving the production efficiency of the present invention; the lifting and lowering of the pen holder carrying jig 53 enables the pen holder carrying jig 53 to be equipped with multiple rotating pen holders.

[0051] Specifically, the plate-shaped pen holder carrying jig 53 is provided with multiple rows of pen insertion slots 531 for inserting the rotating pen holder from bottom to top, and the push rod 521 pushes the rotating pen holder carried by the pen holder moving frame 12 so that the rotating pen holder can be inserted into the pen insertion slot 531 of the pen holder carrying jig 53. In actual application, the jig lifting drive device 54 drives the pen holder carrying jig 53 to rise or fall so that the multiple rows of pen insertion slots 531 on the pen holder carrying jig 53 can all be inserted with the rotating pen holder. Preferably, the fourth sliding seat 522 is provided with a plurality of push rods 521 along the length direction of the pen holder support frame 11, the pen holder bearing platform 51 is provided with a plurality of pen holder bearing grooves 511 along the length direction of the pen holder support frame 11, and the plurality of pen holder bearing grooves 511 are provided one-to-one with the plurality of push rods 521; the pen holder bearing fixture 53 is provided with a plurality of pen insertion grooves 531 in a rectangular array, and the plurality of pen insertion grooves 531 in each row are provided one-to-one with the plurality of pen holder bearing grooves 511.
