The specific embodiment

Below in conjunction with specific embodiment the utility model is done further concrete detailed description the in detail, but embodiment of the present utility model is not limited to this, the technological parameter for not indicating especially can carry out with reference to routine techniques.

Embodiment

As shown in Figure 1.The automatic heat-pipe working medium perfusion equipment of the utility model is used for opposite heat tube and carries out the working medium perfusion, and it comprises: heat pipe is laterally exported hopper 2, heat pipe clamping arm 4, and working medium filling mechanism 3, and heat pipe vertically reclaims hopper 5.In the present embodiment, the tubaeform cross sectional shape that heat pipe is laterally exported hopper 2 and had that inlet point 21 is large, discharging opening 23 is little; Heat pipe clamping arm 4 is arranged at discharging opening 23 places that heat pipe is laterally exported hopper 2; Working medium filling mechanism 3 is arranged at the top of heat pipe clamping arm 4; Heat pipe vertically reclaims hopper 5 and is arranged at the opposite that heat pipe is laterally exported hopper 2.

The inlet point 21 that heat pipe is laterally exported hopper 2 tops is larger, can place many heat pipes to be processed 1, and the diameter of the heat pipe 1 that the Width of below discharging opening 23 is to be processed is slightly large, can only pass through a heat pipe to be processed 1.In order to prevent from occuring at the changes of section place that heat pipe is laterally exported hopper 2 phenomenon of card pipe, arrange at this place with eccentric axis of revolution or with the swing arm 22 of material shaking piece, by a driven by motor (not shown).Discharging opening 23 belows are provided with the push rod 24 of band fluting, and this fluting 25 can only hold a heat pipe to be processed 1, and the push rod 24 of this band fluting is by carrying action before and after the cylinder band action.

Heat pipe clamping arm 4 is to affect that can the utility model be realized stablizing, the pith of failure-free automated production.Heat pipe clamping arm 4 has 3DOF, comprise copper pipe clamping device 41,90 ° of pivot arms 42 and 90 ° are stretched and are balanced platform 43, and this copper pipe clamping device 41 is fixed on the front portion of these 90 ° of pivot arms 42, and the afterbody of these 90 ° of pivot arms 42 is fixed on these 90 ° and stretches and balance on the platform 43.

Working medium filling mechanism 3 is the key components that guarantee the utility model perfusion precision.Working medium filling mechanism 3 is comprised of antidrip syringe needle 31, copper pipe registration device 33 and syringe needle holding device 32, be provided with a through hole in this syringe needle holding device 32, this antidrip syringe needle 31 is drawn by a cylinder, up-and-down movement in this through hole, this copper pipe registration device 33 is fixed on the below of this syringe needle holding device 32.The antidrip syringe needle 31 of working medium filling mechanism 3 is connected with the liquid outlet of precision metering pump by flexible pipe, and the liquid sucting port of this precision metering pump is connected (flexible pipe, precision metering pump and working medium tank are not shown in the figures) by flexible pipe with the working medium tank.

Heat pipe vertically reclaims 15 ° of the base plate 51 relative level face tilts of hopper 5.As shown in Figure 2, the both sides that heat pipe vertically reclaims hopper 5 all have a chute 54, and this base plate 51 is moving up and down to be arranged at this on the chute 54.Heat pipe vertically reclaims and has a notch 52 that can vertically pass through heat pipe 1 to be processed on the hopper 5, and a check valve 53 with spring is equipped with on these notch 52 tops.

Automatically the working process of heat-pipe working medium perfusion equipment is as follows:

At first, many heat pipes to be processed 1 are put into the inlet point 21 that heat pipe is laterally exported hopper 2 sidewards, starter motor drives with eccentric axis of revolution or with the swing arm 22 of material shaking piece, prevents from occurring at the changes of section place that heat pipe is laterally exported hopper 2 phenomenon of card pipe.

When fluting 25 places of the push rod 24 of slotting at band detected the signal of heat pipe to be processed 1 arrival, cylinder was released the push rod 24 of band fluting, delivers to heat pipe clamping arm 4 places together with heat pipe to be processed 1.

After copper pipe clamping device 41 was clamped heat pipe, the push rod 24 of band fluting resetted, and waits for feeding next time.Then 90 ° of pivot arms 42 together with 90 ° of heat pipes to be processed 1 in the lump clickwise, make copper pipe clamping device 41 the symmetrical longitudinal axis of heat pipe coaxial with the symmetrical longitudinal axis of antidrip syringe needle 31.Then stretch and balance platform 43 certain distance that up rises for 90 °, make the mouth of pipe of heat pipe arrive copper pipe registration device 33, copper pipe registration device 33 is fixed the nozzle position of copper pipe.

Need to prove that in order to improve the production efficiency of automation, the homing action of the push rod 24 of band fluting and the spinning movement of 90 ° of pivot arms 42 can be carried out simultaneously.

Antidrip syringe needle 31 down enters by syringe needle holding device 32 under the draw of its cylinder and carries out working medium perfusion in the copper pipe to be processed 1.The groundwater increment of working medium is by the accurate control of precision metering pump.After perfusion is finished, antidrip syringe needle 31 up resets, copper pipe registration device 33 is decontroled the mouth of pipe of copper pipe, stretch for 90 ° and balance platform 43 and down get back to the original place, then stretch and balance 90 ° of platform 43 left-hand revolutions for 90 °, the heat pipe of finishing perfusion is entered heat pipe by notch 52 and check valve 53 vertically reclaim hopper 5.The effect of check valve 53 is to prevent from entering the heat pipe that heat pipe vertically reclaims hopper 5 to drop out by notch 52.Base plate 51 can carry out height adjustment by the chute 54 that heat pipe vertically reclaims hopper 5 both sides, adapts to the production of the heat pipe to be processed 1 of different pipe ranges.After copper pipe clamping device 41 is put into heat pipe heat pipe and vertically reclaimed hopper 5, stretch for 90 ° and balance 90 ° of platform 43 clickwises and get back to the original place, 90 ° of 90 ° of pivot arm 42 left-hand revolutions reset simultaneously, take off a heat pipe to be processed 1.

So go round and begin again, present embodiment can be finished the automation working medium perfusion of all heat pipes to be processed 1.In actual applications, the homing action of antidrip syringe needle 31 can carry out simultaneously with the action that copper pipe registration device 33 is decontroled the mouth of pipe of copper pipes, and 90 ° stretched down homing action and 90 ° of actions of left-hand revolution of balancing platform 43 and can carry out simultaneously, to enhance productivity.

Just can realize preferably the utility model as mentioned above.

Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
