[0035] The working principle of the syringe assembly device provided by the utility model is as follows:

[0036] This solution also has an electric control cabinet, which is installed on the equipment. When in use, each electrical device can be started and operated through the electric control cabinet. The power connection method of each electrical device is an existing mature technology, which is a well-known technology for people in this field and will not be described in detail here.

[0037] When in use, first use the feeding device to push the syringe into the placement slot 5, then start the first electric telescopic rod 8, so that the first electric telescopic rod 8 drives the arc plate 9 to slide, and then the arc plate 9 clamps and fixes the syringe, and at the same time, the buffer pad 10 buffers the clamping force of the arc plate 9, thereby ensuring that the syringe will not be damaged. After the syringe is loaded, start the motor 4, so that the output shaft of the motor 4 drives the connecting plate 3 to rotate, so that the connecting plate 3 drives the syringe to rotate synchronously, so that the other placement slot 5 slides to the feeding device, and at the same time, turn off the motor 4 to perform the feeding operation.

[0038] When the syringe slides to the bottom of the piston rod, the driving cylinder 6 is started, so that the driving cylinder 6 drives the piston rod to slide down, and then pushes the piston rod into the syringe. At the same time, the guide wheel 14 guides the piston rod. When the piston rod slides into the syringe, the second electric telescopic rod 11 is started, so that the second electric telescopic rod 12 drives the guide wheel 14 to slide away from the piston rod, and then the driving cylinder 6 pushes the piston rod completely into the syringe. After installation, the thumb cylinder 7 is started, so that the clamping plate of the thumb cylinder 7 is away from the piston rod, and then the driving cylinder 6 is started to return the thumb cylinder 7 to the next piston rod installation operation;

[0039] When the assembled syringe rotates to the top of the collection box 17, the first electric telescopic rod 8 is started to slide the arc plate 9 away from the syringe, and then the third electric telescopic rod 15 is started to drive the push plate to push the syringe out, so that the syringe is discharged into the collection box 17 for collection;

[0040] When the guide wheel 14 needs to be replaced, first press the limit block so that the limit block compresses the reset spring, and then the limit block slides into the installation groove, then take out the positioning rod 19, make the mounting frame 13 slide off the support plate 12, and then replace the guide wheel 14, which is relatively quick to replace.
