DETAILED DESCRIPTION

[0035] REFERENCE Figure 1 And Figure 2 The core rod pulling device comprises a rack 100, a heat pipe storage bin 200, a straightening mechanism 300, a heat pipe conveying mechanism 400, a sweeping mechanism 500, a heat pipe side pushing mechanism 600 and a core rod pulling mechanism 700.

[0036] REFERENCE Figures 1 to 3 The heat pipe storage bin 200 is fixedly installed on the rack 100. The heat pipe storage bin 200 is a conventional storage bin structure, and those skilled in the art can select the specific structure of the heat pipe storage bin 200 according to actual needs.

[0037] The straightening mechanism 300 comprises a straightening roller shaft 310 and a straightening driving part 320. The straightening driving part 320 is fixedly installed on the rack 100, and is provided as a rotating motor. A transmission structure is arranged between the straightening driving part 320 and the straightening roller shaft 310, and comprises a transmission wheel and a transmission belt. The number of the transmission wheels is two, and each of the two transmission wheels is fixedly connected with the straightening roller shaft 310 and the output end of the straightening driving part 320. The transmission belt passes through the two transmission wheels and is in transmission connection with the transmission wheels. The number of the straightening roller shafts 310 is two, and the two straightening roller shafts 310 are arranged along the horizontal direction. A discharging gap is formed between the two straightening roller shafts 310, and the two straightening roller shafts 310 are arranged in parallel with each other. The straightening driving part 320 drives the two straightening roller shafts 310 to rotate in the same direction through the two transmission structures.

[0038] The heat pipe stored in the hot storage bin will fall between the two straightening roller shafts 310 due to the gravity of the heat pipe itself. If the heat pipe is bent, the two straightening roller shafts 310 will straighten the heat pipe during the same direction rotation. When the heat pipe is completely straightened, the heat pipe will fall and pass through the discharging gap. After the heat pipe is straightened, it is beneficial to the subsequent process.

[0039] Specifically, in the embodiment, one of the straightening roller shafts 310 is connected with the rack 100 through a fixed seat, and the other straightening roller shaft 310 is connected with the rack 100 through a sliding seat. The fixed seat is fixed with the rack 100, and the sliding seat can move along the horizontal direction relative to the rack 100. A return spring is arranged between the fixed seat and the sliding seat. The return spring makes the sliding seat always have a tendency to move away from the fixed seat. The rack 100 is threadedly connected with a gap adjusting screw. The gap adjusting screw is arranged on one side of the sliding seat away from the fixed seat. The end of the gap adjusting screw abuts against the sliding seat. The gap adjusting screw cooperates with the return spring to realize that when the gap adjusting screw is rotated, the sliding seat moves close to or away from the fixed seat, so that the distance between the two straightening roller shafts 310 changes, thereby adjusting the width of the discharging gap to adapt to heat pipes of different width specifications.

[0040] The heat pipe conveying mechanism 400 is provided as a conventional belt conveying mechanism. It is worth noting that the surface of the conveying belt of the heat pipe conveying mechanism 400 is uniformly provided with heat pipe clamping grooves for clamping the heat pipe and conveying the heat pipe forward. The heat pipe conveying mechanism 400 is provided with a conveying surface.

[0041] The flattening mechanism 500 comprises a flattening driving member 510 and a flattening roller 520. The flattening driving member 510 is fixedly installed on the rack 100, and the flattening driving member 510 is arranged as a rotating motor. In the embodiment, the flattening roller 520 is arranged as a brush roller, the flattening roller 520 is arranged above the conveying surface, and the output end of the flattening driving member 510 is in transmission connection with the flattening roller 520 through a belt transmission structure. In other embodiments, the output end of the flattening driving member 510 can also be directly fixedly connected with the flattening roller 520, so that the flattening driving member 510 directly drives the flattening roller 520 to rotate. Those skilled in the art can select the connection mode of the flattening driving member 510 and the flattening roller 520 according to actual needs.

[0042] The heat pipe side pushing mechanism 600 is arranged on the side of the flattening mechanism 500 away from the straightening mechanism 300.

The side pushing moving plate 620 is fixedly connected with the output end of the side pushing driving member 610. The side pushing driving member 610 is used for driving the side pushing moving plate 620 to move close to or away from the side pushing fixed plate, and the side pushing moving plate 620 is used for pushing the heat pipe to one side of the side pushing fixed plate, so that one end of the heat pipe is aligned.

[0043] The core pulling rod mechanism 700 is provided with a core rod end, a heat pipe end and a core pulling center surface. The core pulling center surface coincides with the conveying surface. The core rod end and the heat pipe end are arranged on the two sides of the heat pipe conveying mechanism 400 respectively.

[0044] With reference to Figures 4 to 6 , the core pulling rod mechanism 700 comprises a clamping driving structure 710, a core pulling assembly 720, a core pulling stop piece 730 and a core pulling driving structure 740.

[0045] Specifically, in the embodiment, the core pulling assembly 720 comprises two clamping swing arms 721, the two clamping swing arms 721 are arranged in parallel with each other, and the two clamping swing arms 721 rotate around two rotation axes which are parallel with each other. In other embodiments, the two clamping swing arms 721 can also be arranged as a clamping arm structure which can move close to or away from each other in the up-down direction. Those skilled in the art can select to use the clamping swing arm 721 or the clamping arm structure according to actual needs.

[0046] The pull core assembly 720 is provided with pull core clamping portions 722 arranged at the end of the core rod. The number of the pull core clamping portions 722 is two, and the pull core clamping portions 722 are arranged in one-to-one correspondence with the clamping swing arms 721. The two pull core clamping portions 722 are arranged on the upper and lower sides of the core center surface respectively, and are relatively movable. The two pull core clamping portions 722 are driven to approach or move away from the core center surface by the clamping drive structure 710.

[0047] Specifically, in the embodiment, the core rod mechanism 700 is further provided with a baffle structure 760, which is connected with the side pushing limiting plate 630 to limit the heat pipe.

[0048] Specifically, in the embodiment, the pull core clamping portions 722 are arranged in a roller structure, and are arranged at the end of the clamping swing arm 721 away from the heat pipe. The pull core clamping portions 722 are rotationally connected with the clamping swing arm 721.

[0049] The pull core drive structure 740 is a rotary motor, which drives the rotation of the pull core clamping portions 722. The two pull core clamping portions 722 rotate in opposite directions. Specifically, in the embodiment, the two pull core clamping portions 722 are connected by a synchronous rotation assembly, so that the two pull core clamping portions 722 can rotate synchronously.

[0050] The synchronous rotation assembly includes a synchronous gear 751 and a synchronous structure 752.

[0051] The synchronous gear 751 is arranged at the end of the heat pipe. The number of the synchronous gears 751 is two, and the two synchronous gears 751 are respectively mounted on the two clamping swing arms 721. The central axis of the synchronous gear 751 coincides with the rotation axis of the corresponding clamping swing arm 721, and the two synchronous gears 751 are meshed with each other.

[0052] Since the distance between the synchronous gear 751 and the pull core clamping portion 722 is far, a transmission structure needs to be arranged between the synchronous gear 751 and the pull core clamping portion 722 to realize power transmission therebetween. In the present scheme, the synchronous structure 752 is used to realize power transmission between the synchronous gear 751 and the pull core clamping portion 722. The number of the synchronous structures 752 is two, and the two synchronous gears 751 are respectively arranged on the two clamping swing arms 721. The synchronous gear 751 and the corresponding pull core clamping portion 722 are drivingly connected through the synchronous structure 752. The synchronous structure 752 includes a synchronous pulley and a synchronous belt. The number of the synchronous pulleys is two, and the two synchronous pulleys are respectively fixed with the synchronous gear 751 and the pull core clamping portion 722. The synchronous belt passes through the two synchronous pulleys and is drivingly connected with the two synchronous pulleys. Of course, the synchronous structure 752 is provided with a tension pulley for keeping the synchronous belt taut.

[0053] Specifically, in the present embodiment, the clamping driving structure 710 is provided as a linear cylinder, and the clamping driving structure 710 is connected with the upper clamping swing arm 721 through a universal floating joint. The clamping driving structure 710 drives the upper clamping swing arm 721 to rotate around its rotation axis, so that the end of the clamping swing arm 721 away from the rotation axis is close to or away from the core pulling center plane, thereby driving the core clamping part 722 to be close to or away from the core pulling center plane, so that the two core clamping parts 722 clamp the core rod.

[0054] A linkage structure is provided between the two clamping swing arms 721, and the linkage structure includes a linkage sliding block 723 and a linkage groove 724. The linkage groove 724 is provided on the upper clamping swing arm 721, and the two opposite side walls of the linkage groove 724 are provided as driving side walls. The outer surface of the linkage sliding block 723 is provided as a cylindrical surface, and the outer surface of the linkage sliding block 723 is always in abutment with any driving side wall. When the upper clamping swing arm 721 is driven by the clamping driving structure 710 to rotate around the rotation axis, since the linkage sliding block 723 is always in abutment with the driving side wall, the driving side wall will drive the linkage sliding block 723 to move, thereby driving the lower clamping swing arm 721 to rotate around its own rotation axis, so as to realize the synchronous movement of the two clamping swing arms 721, thereby realizing the action that the core clamping parts 722 of the two clamping swing arms 721 are simultaneously close to or simultaneously away from the core pulling center plane.

[0055] The core rod stopper 730 is provided on the side of the core clamping part 722 close to the end of the heat pipe. The core rod stopper 730 is provided with a core rod passing groove, and the width of the core rod passing groove is smaller than the diameter of the heat pipe when the core rod is pulled out, so that the width of the core rod passing groove is only for the core rod to pass through, so as to avoid that the heat pipe is pulled out of the heat pipe conveying mechanism 400 by the core clamping part 722, and also avoid that the heat pipe is damaged due to contact with the core clamping part 722, so that the core pulling work can be smoothly carried out.

[0056] Specifically, in the present embodiment, the core rod stopper 730 includes two stopper structures 731, and the core rod passing groove is in the gap between the two stopper structures 731. The two stopper structures 731 are respectively arranged corresponding to the two clamping swing arms 721, and the stopper structure 731 is installed on the clamping swing arm 721. The stopper structure 731 will move to be close to or away from the core pulling center plane with the rotation of the clamping swing arm 721.

[0057] Specifically, in the present embodiment, the blocking piece structure 731 is rotationally connected with the corresponding clamping swing arm 721, so that the blocking piece structure 731 can rotate within a certain range relative to the clamping swing arm 721, thereby adjusting the gap formed between the two blocking piece structures 731 (i.e., adjusting the width of the core rod passing slot), so as to adapt to core rods of different diameters, thereby improving the adaptability of the present core pulling device to different models of products. Specifically, the blocking piece structure 731 and the clamping swing arm 721 are connected through structures such as return springs and adjusting screws to realize the adjustability between the blocking piece structure 731 and the clamping swing arm 721.

[0058] The rack 100 is fixedly installed with a core rod collecting groove 110 and a heat pipe collecting groove 120. The core rod collecting groove 110 is arranged at the core rod end of the core pulling mechanism 700, and the heat pipe collecting groove 120 is arranged at the most front end of the heat pipe conveying mechanism 400.

[0059] The implementation process of the present core pulling device is as follows: the staff first puts a plurality of heat pipes into the heat pipe storage bin 200, and then starts the core pulling device. The heat pipes fall from the heat pipe storage bin 200 to the straightening mechanism 300, the straightening mechanism 300 straightens the bent heat pipes, and after the heat pipes are straightened, the heat pipes can fall from the feeding gap and be conveyed forward by the heat pipe conveying mechanism 400.

[0060] During the forward movement of the heat pipes driven by the heat pipe conveying mechanism 400, the heat pipes first pass through the flattening mechanism 500. When the heat pipes pass through the flattening mechanism 500, if the heat pipes are stacked, the flattening rollers 520 of the flattening mechanism 500 will sweep the heat pipes above to the rear, so that only one layer of heat pipes passes below the flattening mechanism 500, thereby avoiding the occurrence of adverse conditions such as poor core pulling quality caused by heat pipe stacking in subsequent processes.

[0061] After the heat pipes pass through the flattening mechanism 500, they are conveyed by the heat pipe conveying mechanism 400 to the heat pipe side pushing mechanism 600. The heat pipe side pushing mechanism 600 pushes the heat pipes to one side, so that the end portions of the heat pipes are aligned to facilitate the smooth progress of subsequent processes.

[0062] After the heat pipes pass through the heat pipe side pushing mechanism 600, they are conveyed by the heat pipe conveying mechanism 400 to the core pulling mechanism 700. The clamping driving structure 710 drives the two clamping swing arms 721 to move close to each other at one end of the heat pipe, so that the two core pulling clamping portions 722 clamp the core rod. Then, the core pulling driving structure 740 drives the core pulling clamping portion 722 to rotate, and the core rod moves away from the heat pipe end due to friction. The heat pipe is blocked by the core pulling blocking piece 730 and remains on the heat pipe conveying mechanism 400. The pulled core rod falls into the core rod collecting groove 110, and the heat pipe is continuously conveyed by the heat pipe conveying mechanism 400, and finally falls into the heat pipe collecting groove 120.

[0063] The preferred embodiments of the present application are specifically described above, but the present application is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. The equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
