[0038] As an optimized solution of the embodiment of the present invention, please refer to Figure 1 and Figure 5 , the system further includes a compaction device 5 for compacting the reference electrode in the zirconium tube. The compaction device 5 is located in the path from the molybdenum needle inserting device 4 to the finished product discharging device 8. In this embodiment, after the reference electrode is put into the zirconium tube, it needs to be compacted, and the compaction device 5 can be used for the operation. The compaction device 5 includes a cylinder 50 and a hammer rod 52 driven by the cylinder 50. The reference electrode powder in the zirconium tube is gradually compacted by hammering the reference electrode in the zirconium tube with the hammer rod 52.

Specifically, the lifting detection device 6 includes a lifting clamp 60 to clamp the molybdenum needle, the zirconium tube is lifted up, and then put back into the zirconium tube carrier 10 after a while. The height of the molybdenum needle is detected by the photoelectric signal induction of the height detection sensor 61, so as to judge whether the molybdenum needle is loose.

In this embodiment, the zirconium tube vibrating disk 20 can be filled with zirconium tubes. As the zirconium tubes are vibrated and fed onto the conveyor belt 21, the conveyor belt 21 sends the zirconium tubes to the zirconium tube clamping mechanism 22, and the zirconium tube clamping mechanism 22 grabs the zirconium tubes and sends them into the zirconium tube carrier 10. During the transfer of the conveyor belt 21, a dislocation mechanism 23 can be used to separate the adjacent zirconium tubes. The dislocation mechanism 23 can use vibration to shake the adjacent zirconium tubes apart, or can also use a channel that only allows one zirconium tube to pass through to restrict the entry of zirconium tubes, so that there is only one zirconium tube when it reaches the zirconium tube clamping mechanism 22.

[0042] As an optimized solution of the embodiment of the present invention, please refer to Figure 1 and Figure 3, the reference electrode powder adding device 3 includes a weighing powder adding mechanism 31 and a powder adding funnel 30 for adding the reference electrode to the weighing powder adding mechanism 31, and the weighing powder adding mechanism 31 pours the weighed reference electrode into the zirconium tube. In this embodiment, the reference electrode is added by the reference electrode powder adding device 3, and the reference electrode powder adding device 3 is funnel-shaped as a whole, and the tip discharges the material into the zirconium tube. It has its own weighing unit, and the amount of reference electrode to be added can be weighed and added to ensure accuracy. Preferably, it also includes a photoelectric detection sensor 32 for detecting whether there is a zirconium tube on the zirconium tube carrier 10. When a zirconium tube is detected, the signal is transmitted to the weighing powder adding mechanism 31 for powder adding operation. Before the weighing powder adding mechanism 31 works, the photoelectric detection sensor 32 is used to detect whether there is a zirconium tube in the zirconium tube carrier 10. If it is detected that there is no zirconium tube, the powder adding action is turned off.

[0043] As an optimization solution of the embodiment of the present invention, please refer to Figure 1 and Figure 8 The finished product unloading device 8 includes an unloading module 80, a finished product box 81 and an NG box 82.

The zirconium tube carrier 10 is cylindrical, and the zirconium tube carrier 10 has a mounting position for the zirconium tube to insert. There are two mounting positions. The two mounting positions are arranged at intervals, and the sizes of the two mounting positions are different. In this embodiment, the molybdenum needle inserting device 4 also has a molybdenum needle vibrating tray 41 to send the molybdenum needle to the molybdenum needle handling mechanism 46. The molybdenum needle handling mechanism 46 is used to transport the molybdenum needle into the zirconium tube, and cooperate with the vibrator 40 to provide a vibration force to facilitate the molybdenum needle to be introduced into the zirconium tube carrier 10. In order to make the introduction speed faster and more accurate, the guide block 42 can also be used in cooperation. The guide block 42 has a hole. After its position is set, controlling the molybdenum needle to pass through the hole can ensure that the molybdenum needle is inserted into the zirconium tube.
