[0039] When in use, the hinge assembly and the bellows torsion spring automatic opening mechanism are replaced with an SMC single guide rod cylinder mechanism. At this time, the output end is retracted by driving the SMC single rod cylinder 27. At this time, the upper connecting plate 25 can be pulled back, and then the upper cavity 7 can be pulled to rotate by the upper connecting plate 25. At this time, the upper cavity 7 and the lower cavity 6 can be separated. At this time, the bellows can be placed between the upper cavity 7 and the lower cavity 6, and then the upper cavity 7 and the lower cavity 6 are combined together by the handle 8. At this time, the bellows can be clamped. At this time, the probe 1 is pressed and then approaches the proximity switch A4 to send a signal, and then the equipment is started to weld the bellows. After welding, the SMC single rod cylinder 27 is driven to retract the output end to realize the automatic separation of the upper cavity 7 and the lower cavity 6.

Then, the upper cavity 7 can be lifted up by the pressing arm 30, and the upper cavity 7 and the lower cavity 6 can be separated. At this time, the bellows can be placed between the upper cavity 7 and the lower cavity 6, and then the upper cavity 7 and the lower cavity 6 are combined together by the handle 8. At this time, the bellows can be clamped, and the probe 1 is pressed and approaches the proximity switch A4 to send a signal, and then the equipment is started to weld the bellows. After welding, the Distech 40 clamping cylinder 43 is driven to retract the output end to realize the automatic separation of the upper cavity 7 and the lower cavity 6.

[0042] Working principle: When in use, the upper cavity 7 can be opened by the handle 8. At this time, the bellows can be placed between the upper cavity 7 and the lower cavity 6, so that the upper cavity 7 and the lower cavity 6 are combined into one, and the bellows can be fixed, and the probe 1 will contact the bellows, so that the probe 1 is close to the proximity switch A4, and the indicator light of the proximity switch A4 can be turned on. At this time, the equipment can be started to weld the bellows. When the welding is completed, the handle 8 is released. Since the upper cavity 7 and the lower cavity 6 are in contact, the torsion spring 15 in the hinge will twist. Therefore, after the handle 8 is released, the upper cavity 7 will automatically open, and then the bellows can be taken out. When the bellows is taken out, the spring 44A can lift the probe 1 to reset it.
