[0032] Furthermore, in this embodiment, the filling device 6 includes a filling needle 61 and a filling drive 62 for driving the filling needle 61 to rise and fall, and a filling pipeline 63 is connected to the filling needle 61. After the conveying track 4 conveys the generator conveying member 5 to the filling device 6, the filling drive 62 drives the filling needle 61 to descend, and the filling pipeline 63 injects the liquid medicine into the column assembly 200 through the filling needle 61. After reaching the set filling volume, the filling needle 61 rises and resets, and the filling process is completed. The filling device 6 has a simple overall structure and high operation efficiency.

[0033] Furthermore, in this embodiment, the elution device 7 includes an elution needle 71 and an elution drive 72 for driving the elution needle 71 to rise and fall, and the elution pipeline 73 is connected to the elution needle 71.

[0034] Furthermore, in this embodiment, the assembly device 8 includes a needle assembly grabbing member 81 and an assembly driving member 82 for driving the needle assembly grabbing member 81 to rise and fall and move. The conveying track 4 conveys the generator conveying member 5 to the assembly device 8, the needle assembly grabbing member 81 grabs the needle assembly 100, and moves forward to align the needle assembly 100 with the column assembly 200, and the assembly driving member 82 drives the needle assembly grabbing member 81 to descend, and assembles the needle assembly 100 to the column assembly 200, and then the needle assembly grabbing member 81 rises, retreats and resets, and the assembly process is completed. The assembly device 8 has a simple overall structure and high operation efficiency.

[0035] Furthermore, in this embodiment, the cover removal device 91 includes a first needle cover grabbing member 911 and a cover removal driving member 912 for driving the first needle cover grabbing member 911 to rise and fall and move. The assembled cold column assembly moves to the cover removal device 91 along the conveying track 4, and the cover removal driving member 912 drives the first needle cover grabbing member 911 to descend, and the first needle cover grabbing member 911 grabs the needle cover and rises to remove the needle cover, and the cover removal driving member 912 drives the first needle cover grabbing member 911 to move above the needle cover positioning portion 53, and then descends to place the needle cover on the needle cover positioning portion 53, and finally the cover removal driving member 912 drives the first needle cover grabbing member 911 to reset, and the cover removal process is completed. The overall structure of the cover removal device 91 is simple and the operation efficiency is high.

The pressing member 913 can be, for example, a pressure rod, a pressure plate, etc., and is driven to swing up and down by a telescopic driving member such as a cylinder or an electric push rod. After the assembled cold column assembly moves to the cover removal device 91 along the conveying track 4, the pressing member 913 swings downward to press the cold column assembly, which facilitates the separation of the needle cover from the needle assembly 100. Then, the first needle cover grabbing member 911 grabs the needle cover and lifts it, further improving the reliability of the cover removal device 91. The specific structure of the capping device 93 can be the same as that of the cover removal device 91, including a second needle cover grabbing member 931 and a capping driving member 932 for driving the second needle cover grabbing member 931 to rise and fall and move. The capping process is opposite to the cap removal process, that is, the capping device 93 is used to take out the needle cover of the needle cover positioning part 53 and place it on the needle assembly 100 after the test.

Of course, in other embodiments, the number of generator storage stations 41 and each device can be further increased. The feeding mechanism 22 grabs the upper two groups of needle assemblies 100 and two groups of column assemblies 200 of the feed channel 21, and feeds them to the two generator conveying members 5 or storage stations 41 on the conveying track 4. The two sets of devices performing the same action are regarded as one station, which can further improve the assembly efficiency of the system, and if a single device at any station fails, the system can still keep running, which is conducive to improving the reliability of the system.

[0040] As a preferred embodiment, the filling pipeline 63, the rinsing pipeline 73 and the test pipeline 923 are arranged in sequence along the conveying direction of the conveying track 4, so that the filling pipeline 63, the rinsing pipeline 73 and the test pipeline 923 are conveniently connected to the filling needle 61, the rinsing needle 71 and the test needle 921 respectively, thereby saving the length of the connecting pipe. Of course, in other embodiments, the filling pipeline 63, the rinsing pipeline 73 and the test pipeline 923 can also be arranged in other ways.

The needle assembly grasping member 81 grasps the needle assembly 100, and moves forward to align the needle assembly 100 with the column assembly 200. The assembly driving member 82 drives the needle assembly grasping member 81 to descend, and assembles the needle assembly 100 onto the column assembly 200. Then, the needle assembly grasping member 81 rises, retreats and resets, and the assembly process is completed.
