[0101] Working principle and usage process of this invention:

[0102] During use, the electrical components on the device are electrically connected to and controlled by an external control system.

[0103] During this process, the pen body is conveyed and constrained by the conveyor belt 103 and its limiting strips, while the pen caps are fed through the unloading channel 215. The pen caps in the unloading channel 215 are output by the feeding vibratory feeder and enter the unloading chamber 211 through the unloading channel 215, falling into the guide seat 212. At this time, the conveyor belt 103 stops conveying, and the pneumatic cylinder 214 is activated. The pneumatic cylinder 214 pushes the connecting block 219, and the pusher of the connecting block 219 pushes the pen caps that have entered the guide seat 212. At the same time, the guide plate 216 is simultaneously pushed forward. The rack 223 at the bottom of the guide plate 216 can push the gear 222 on the rotating shaft 225 to rotate the rotating shaft 225, thereby driving the rack 223 on the push plate 226. The push plate 226 pushes the rack 223 at the outer end, causing the pen tip interface 224 on the rack 223 to dock with another pen tip. The rack 223 is hollow inside. The pen tip interface 224 docks with and blocks the pen tip, while the rack 223 receives the pen tip. In this way, the push head of the connecting block 219 will push the pen cap that enters the guide seat 212 to dock with the corresponding pen tip, thus completing the capping at one end.

[0104] After completion, the conveyor belt 103 is started again to transport the pen body. After reaching the bottom of the mounting frame 2 701, it stops again and the pneumatic cylinder 4 702 is started to drive the bottom component to descend. The suction cup 704 descends synchronously and absorbs and fixes the pen body through the suction nozzle at the bottom. Then the pneumatic rotary cylinder 703 is started to rotate and adjust the position of the pen body before placing it in the conveying position and transporting it again. The other end of the pen body is then connected and capped according to the above arrangement.

[0105] After the cap is capped, the pen body is continuously conveyed. The cap at one end of the pen body will be blocked by the guide plate 804 due to the poor angle. After being constrained by the guide plate 804, the pen cap rotates to adjust its position to ensure that the pen body is conveyed in a consistent position. It should also be noted that during the conveying process, the personnel need to rotate and adjust the threaded adjustment rod 802 to ensure that the height of the guide plate 804 at the bottom of the connector 803 meets the required pen cap blocking adjustment requirements.

[0106] During the capping process, the pneumatic cylinder 214 pushes the front connecting block 219, which in turn drives the piston 615 to reciprocate synchronously. The piston 615 moves in the air collection cylinder 611, at which time external air enters the interior through the one-way air inlet valve 614 and is pushed into the air guide pipe 612 through the one-way air outlet valve 613. The air is then input into the air inlet chamber 625 through the air guide pipe 612. The air inlet chamber 625 inflates the telescopic air bag 624, causing the telescopic air bag 624 to push the support rod 623. The pneumatic effect causes the square cylinder 622 to be lifted by the support rod 623. The height of the lifting is synchronized with the conveyor belt 103, ensuring that the pen cap is inflated during docking.

[0107] When the pen body with the cap on is fully connected and reaches the position of the pen tip 404, and the pen in the conveyor belt 103 corresponds to the external insertion interface 904 on the cover plate 903, the conveyor belt 103 stops conveying, and the pneumatic cylinder 401 is activated to push the mounting strip 403. At that time, the mounting strip 403 can push the pen behind the cap through the pen tip 404, causing it to pass through the external insertion interface 904 and enter the receiving box 901. Then the inner cap of the pen is inserted into the inner insertion interface 902 to realize the internal receiving and storage of the pen.

[0108] After the receiving box 901 has completed inserting all the receiving units, the motor on the electric tilting component 326 is activated to axially drive the mounting plate 322, causing the mounting plate 322 to rotate the bracket 321. At that time, the receiving box 901 inside the bracket 321 will be driven to tilt downwards, and the receiving box 901 will slide into the unloading channel 327. As the receiving box 901 slides into the unloading channel 327, the upper contact switch 324 will also make electrical contact with the lower contact switch 325 on the second mounting plate 323 as the mounting plate 322 tilts downwards. At that time, the electric tilting component will rotate. The motor on component 326 drives the mounting plate 322 to flip up and reset, and the vent valve 626 also simultaneously vents air electrically, causing the square cylinder 622 to enter the lowering state. When it descends to the lowering position, the receiving box 901 can be replenished. The receiving box 901 is slid into the baffle plate 315 at the top of the mounting frame 311 through the feeding channel 314. Then, the pneumatic cylinder 312 is activated to push the pusher plate 313. The pusher plate 313 is right-angled and pushes the receiving box 901 into the bracket 321, so that subsequent receiving and packing operations can be carried out.
