[0146] Specifically, in implementation, the pre-rotation assembly is used to pre-twist and install the refill tube into the pen barrel. The first driving motor provides the driving force. The first driving motor drives the first rotating shaft to rotate through a belt, which can quickly guide and smooth the connection between the refill tube and the pen barrel, and at the same time play a role in quickly guiding the head. The fastening assembly uses the second driving motor to provide the driving force, and transmits the force rigidly through gears, avoiding the slipping phenomenon that occurs when using a belt to transmit the force, and is suitable for transmitting force at high speed. At the same time, through the transmission of force by gears, the pen barrel that is twisted in place reaches a certain strength, can be easily opened, and will not loosen automatically. Through the cooperation of the pre-rotation assembly and the fastening assembly, the screwing installation of the refill tube and the pen barrel is quickly realized.

[0147] Working principle:

[0148] Before feeding, the pen barrel 900 is placed on the pen barrel blanking vibrating disk 204. After being vibrated by the pen barrel blanking vibrating disk 204, it successively passes through the pen tube through groove and falls into the pen barrel sorting assembly 201. Then, after being sorted by the pen barrel sorting assembly 201, the sorted pen barrels are successively output from the bottom end of the pen barrel sorting assembly 201. The blanking limit assembly 202 is connected to the bottom end of the pen barrel sorting assembly 201. By the work of the blanking limit assembly 202, it is ensured that the pen barrels 900 fall into the turning assembly 203 one by one after being output. When the pen barrel 900 falls into the turning assembly 203 via the blanking limit assembly 202, it falls horizontally, but during the pen installation process, the pen barrel needs to fall vertically. The turning assembly 203 of the present application embodiment realizes the automatic turning of the pen barrel 900.

[0149] After being detected by the pen barrel detection device 300 whether the pen barrel 900 is conveyed in place, it is continuously conveyed via the conveying platform 100;

[0150] Before feeding, place the refill tube on the refill tube feeding vibrating disk. After being vibrated by the refill tube feeding vibrating disk, it successively passes through the refill tube pre-positioning assembly 400. The jaw structure is used to clamp the refill tube from the refill tube pre-positioning assembly 404 into the pen barrel of the refill tube fixing assembly 401 to install the refill tube into the pen barrel 900; then it is conveyed by the transfer platform into the next pen combination process.

[0151] Successively, the ink filling device 500 fills ink into the refill tube, and the regulator assembly installation device 600 installs the regulator assembly into the refill tube; then the refill tube and pen barrel connection device 700 connects the refill tube with the installed regulator assembly to the pen barrel 900. Finally, the defective product detection mechanism 800 picks out the defective ballpoint pens. The defective product detection mechanism 800 can use the existing technology to detect defective products, so it will not be elaborated here.
