the second track group 221 is reciprocated by the moving platform assembly 222, continuously receives heat pipes one by one from the rod-taking structure 422, and places the heat pipes in the first heat pipe carrying structure 211 at the head end of the first track group 21, and simultaneously transfers the heat pipes in the first heat pipe carrying structure 211 at the head end of the first track group 21 to the next first heat pipe carrying structure 211 adjacent to the first heat pipe carrying structure 211.

When 3 heat pipes are in place, the compression cylinder 646 acts to drive the pressure plate 644 to press the tail of the heat pipe to position the heat pipe, the lead screw stepping motor 622 starts to go to the rod pulling front position (close to one end of the heat pipe conveying assembly 2) to reach the rear clamping jaw assembly 631 to clamp the core rod, the lead screw stepping motor 622 drives the movable mounting plate 611 and the clamping jaw assembly 631 to move backwards, if the pulling force is over-limited in the process, namely the pulling force reaches a certain value (preset value in PLC, and if the pulling force exceeds the value, the core rod is determined to be defective), the core rod is not loosened or cannot be pulled out smoothly, the clamping jaw assembly 631 is loosened, the PLC carries out recording and rejects and recovers the defective product, the rest clamping jaw assemblies 631 continue to move forwards to the rod pulling rear position (far away from one end of the heat pipe conveying assembly 2), the clamping jaw assembly 631 is loosened after the rod pulling rear position, the core rod is thrown into the core rod accommodating bin 16, the clamping jaw assembly 631 is reset to the rod pulling waiting position (the middle part of the first moving mechanism 62), the heat pipe clamp 64 is reset.

The second track group 221 continues reciprocating movement under the action of the moving platform assembly 222 to perform feeding of a new group of heat pipes, meanwhile, the heat pipes with the mandrel pulled out and the defective heat pipes are conveyed to the tail end of the first track group 21, when the laser sensor at the tail end of the first track group 21 detects that a shielding exists, rod pulling is proved to be absent, the heat pipes are defined as the defective heat pipes, the PLC controls the linear sliding table module 321 to act, the clamping jaw structure 33 grabs the defective heat pipes and puts the defective heat pipes into the defective product display bin 34, the second track group 221 continues transplanting, and the heat pipes with successful rod pulling are discharged to the material receiving bin structure.

Compared with the prior art, the automatic heat pipe picking device has the advantages that the structure is simple, the heat pipes in the feeding bin can be automatically taken out one by one and arranged on the first rail, the heat pipes on the first rail can be transported to the receiving bin step by step in the material taking process for one time, then the pulling of the heat pipe core rods and the sorting of defective heat pipes which are not pulled out are fully automatically realized under the control of the control assembly, after the pulling is finished, the finished heat pipes are finally conveyed into the receiving bin automatically, the automatic feeding, discharging, pulling and defective sorting of the heat pipes are realized, the whole process is efficient and automatic, and the labor cost, the material cost and the financial cost are saved.
