The plugging mechanism 4 includes a plug suction arm 401 and a plug connecting arm 406. The lower end of the plug suction arm 401 is connected to multiple plug suction rods 403. The plug suction rod 403 is an internal hollow tube. The lower end of the hollow tube is connected to a suction cup 404. The pressure column 405 is sleeved on the outer side of the lower end of the plug suction rod 403, and the suction cup 404 protrudes from the lower end of the pressure column 405. The interior of the plug suction arm 401 is a hollow cavity, which is connected to each plug suction rod 403. The front end of the plug suction arm 401 is connected to a vacuum connector 402, and the vacuum connector 402 is connected to a vacuum pump through a hose. The vacuum joint 402 is connected to the cavity inside the plug suction arm 401; the plug connection arm 406 is located below the multiple plug suction rods 403, and multiple first U-shaped channels 412 are provided on the right side of the plug connection arm 406. The front and rear ends of the left side of the plug connection arm 406 are each connected to a baffle cover flip fixing block 410, and the two baffle cover flip fixing blocks 410 are rotatably connected to the baffle cover plate 409, and the left end of the baffle cover plate 409 is connected to a counterweight block 411, and the baffle cover plate 409 contacts the lower end surface of the plug connection arm 406. The counterweight block 411 is connected to the left end of the baffle cover plate 409 to form a flip plate with eccentric characteristics, and the flip plate rotates around the shaft hole on the baffle cover flip fixing block 410. The counterweight block 411 makes the baffle cover plate 409 contact and fit the lower end surface of the plug connection arm 406, and multiple second U-shaped channels 413 are provided on the baffle cover plate 409 corresponding to the multiple first U-shaped channels 412, and the diameter of the second U-shaped channels 413 is smaller than the outer diameter of the fit cap rubber plug. The rear end of the plug suction arm 401 is connected to the plug suction arm driving shaft 407 , the rear end of the plug connection arm 406 is connected to the outer side of the upper end of the plug connection arm driving shaft 408 , and the lower end of the plug suction arm driving shaft 407 is slidably connected to the inside of the plug connection arm driving shaft 408 .

[0024] Specifically, the filling mechanism 3 includes a filling needle drive shaft 303, multiple filling needles 301 and a filling needle mounting plate 302. The multiple filling needles 301 are connected to the filling needle mounting plate 302, and the rear end of the filling needle mounting plate 302 is connected to the filling needle drive shaft 303; the lower end of the filling needle drive shaft 303 and the lower end of the plug arm drive shaft 408 are each independently connected to a group of drive mechanisms, and the filling needle drive shaft 303 is located on the left side of the plug arm drive shaft 408.

[0025] Specifically, the vial conveying mechanism 2 includes an X-axis 201, a Y-axis 202 and a tooling 203. The X-axis 201 and the Y-axis 202 are slidably connected, and the tooling 203 is connected to the Y-axis 202. The X-axis 201 and the Y-axis 202 are each independently connected to a set of servo drive motors, which can drive the tooling 203 to move in two degrees of freedom in a horizontal plane.

[0026] Specifically, the plug conveying mechanism 5 includes a linear track 501 and a vibrating hopper 502. The vibrating hopper 502 is arranged at the right end of the upper end surface of the frame 1. The output end of the vibrating hopper 502 is connected to the linear track 501. The end of the linear track 501 extends to the plug arm 406. The end of the linear track 501 extends to the first U-shaped channel 412 of the plug arm 406 in space, but the two are not mechanically connected.

[0027] Specifically, the container filled with vials is placed in the tooling 203, the X-axis 201 and the Y-axis 202 in the vial conveying mechanism 2 are operated to convey the vials to the filling mechanism 3, and then the filling needle driving shaft 303 moves downward under the drive of the servo motor, thereby driving the filling needle 301 to move downward, and the needle tip is inserted into the vial to start filling. After the filling is completed, the filling needle 301 rises to leave the bottle mouth, and at this time, the X-axis 201 and the Y-axis 202 are operated simultaneously to convey the filled vial to the plugging mechanism 4. The rubber plug in the form of a fit cap is first added to the vibrating hopper 502, and the vibrating hopper 502 combs the rubber plug by vibration, and the combed rubber plug is conveyed to the first U-shaped channel 412 on the plugging arm 406 through the linear track 501. At this time, the filled vial is already located directly below the plug receiving arm 406, and then the plug sucking arm 401 drives the plug sucking rod 403 to move downward, and the suction cup 404 at the lower end of the plug sucking rod 403 first contacts the fit cap rubber plug, and then vacuums the rubber plug, and the plug sucking arm 401 continues to drive the plug sucking rod 403 to move downward. At this time, the flip plate (counterweight block 411 and baffle plate 409) is subjected to the force applied downward by the plug sucking rod 403 through the fit cap rubber plug. When this force reaches a force greater than the gravity of the flip plate, the suction cup 404 is compressed, the pressure column 405 contacts the upper surface of the fit cap, and the flip plate (baffle plate 409) rotates, and then the fit cap rubber plug smoothly passes through the double-layer U-shaped channel to reach the vial mouth. At this time, the plug sucking arm 401 increases the force applied to the fit cap rubber plug through the plug sucking rod 403 and the pressure column 405 until the fit cap rubber plug is successfully added to the vial. This cycle is repeated until all the vials in the container are plugged, and then the X-axis 201 and the Y-axis 202 in the vial conveying mechanism 2 are activated to convey the vials to the discharging position, so that the container containing the vials can be taken out conveniently.
