with reference to fig. 1-14, the heat pipes to be evacuated are first placed in the hopper device 10, and the heat pipes with different lengths can be placed by adjusting the distance between the two material limiting plates 64. And then the ejector cylinder 56 drives the ejector rod 56 and the ejector die 60 at the tail end to eject the heat pipe. And only one heat pipe is jacked each time, the linear guide rail clamp 58 on the guide rail 61 is adjusted to change the position relation of the feeding rod 59, so that the heat pipes with any length in a certain range can be conveniently moved onto the straightening device 12 through the mutual matching relation among the horizontal transmission cylinder 67, the lifting cylinder 68 and the material clamping claw 72 in the feeding device 11 when the feeding detection sensor senses that the heat pipes are jacked. Otherwise this step of loading is repeated. When the heat pipe is transferred to the straightening device, the heat pipe is fixed between the pressing molds 77 and 84 by the pressing cylinder 69, and the straightening cylinder 91 is extended to straighten the front end of the heat pipe by the straightening mold 85. The operation of the above feeding is repeated, the heat pipe is moved to the positioning device 13, and a new heat pipe is transferred to the straightening device 12, on the positioning device, the sliding table cylinder 94 is firstly utilized to shift the guide rail to a position, so that the interference between the material clamping device 6 at the front end of the mechanical arm and the feeding device 11 is avoided when the mechanical arm picks up the material, after the material is in place, the pen-shaped cylinder 107 is firstly extended out, the stop block 108 is enabled to prop against the front end of the heat pipe, and then the push rod 101 is driven by the pushing cylinder 97 to enable the heat pipe to be completely fixed between the stop block 108 and the push rod 101. A pressure reducing valve is arranged on an air path of the propulsion cylinder 97, and meanwhile, the spring 101 can play a role in buffering when being fixed, so that the phenomenon that the heat pipe deforms due to the fact that the air source is stressed forwards and backwards due to overlarge pressure is avoided. After the positioning is determined, the material is grabbed by the material loading clamping jaw 49 in the material clamping device 6 at the tail end of the mechanical arm (meanwhile, the material is discharged by the material discharging clamping jaw 48). After the material grabbing and discharging are completed, the discharging clamping jaw 48 in the material clamping device 6 is controlled firstly, the heat pipe which is vacuumized in the cavity 31 is taken down, then the heat pipe in the material loading clamping jaw 49 is inserted into the cavity 31 through the lower cover plate 33, in the cavity 31, the limiting plate 42 arranged above the sealing device can limit the rising height of the heat pipe, when the mechanical arm controls the heat pipe to be inserted into a correct position, the air cylinder 112 on the vacuum cavity is controlled to drive the lower cover plate 33, the lower cover plate 33 extrudes the sealing ring, the sealing ring is stressed in the axial direction, the sealing ring is deformed in the radial direction, the heat pipe is clamped, and the vacuumizing is started. The vacuum valve connected to the first evacuation line 21 and the vacuum valve connected to the second evacuation line 22 are sequentially opened, the opening time is set by an operator on the touch screen, and each station monitors the vacuum degree during the second evacuation by using a vacuum gauge 27. After the vacuumizing time is over, the oil cylinder 29 is triggered to seal, the floating joint 34 at the front end of the oil cylinder drives the main shaft connecting block 34, the main shaft 40 and the male die 41 in the sealing die, the heat pipe is sealed by cold welding through the male die 41 and the female die 43, sealing is realized, the oil cylinder returns after a certain time, and the vacuumizing process of the heat pipe is over. When the vacuum degree detected by the vacuum gauge 27 does not reach the set vacuum degree at the end of the second vacuum pumping, the cylinder 29 is not operated. Meanwhile, a vacuumizing end signal is sent to the mechanical arm controller to inform the mechanical arm that the blanking can be carried out, after the blanking is finished, the mechanical arm drives the discharging clamping jaw 48 to take the heat pipe out of the cavity 31, and then the vacuumized heat pipe is placed in the material receiving device 14. And repeating the operation to realize the automatic vacuumizing feeding and discharging process of the heat pipe.
