Description

Technical Field

[0001] This utility model relates to the technical field of heat pipe processing equipment, and in particular to an automatic quantitative powder filling device for heat pipes. Background Technology

[0002] A heat pipe is a highly efficient heat-conducting device based on the principle of phase change heat transfer. More specifically, a heat pipe is a vacuum-sealed heat transfer element filled with a specific working fluid, such as pure water or ammonia. It can achieve rapid heat transfer through the evaporation-condensation cycle of the working fluid. As a result, its thermal conductivity far exceeds that of metals such as copper and silver, and it does not require external energy to drive it, belonging to passive heat transfer technology.

[0003] Specifically, the basic manufacturing process of a heat pipe can be broadly divided into four steps: shell processing, core fabrication, working fluid injection and vacuum treatment, and post-processing and testing. After cutting the metal tube, such as copper, aluminum, or stainless steel, to the required length and shrinking the ends using a tube shrinking machine, one end needs to be sealed using a welding machine to form a sealed cavity. Strict control of welding quality is required to prevent leakage. Next, the core is filled with powder and sintered. Finally, a working fluid, such as water, ammonia, or liquid metal, is injected into the core. After injecting the working fluid, residual gas is removed to ensure the vacuum level inside the tube reaches the required standard. The volume is then increased; next, the injection port is sealed by laser welding or cold pressing to achieve a secondary seal.

[0004] Based on this, Chinese patent document CN202269037U discloses an automatic filling machine for electric heating tubes, which includes an electric heating tube clamp, a hydraulic lifting unit, and a vibrating filling disc. The electric heating tube clamp is mounted on a conveyor belt and has insertion holes. The hydraulic lifting unit is connected below the conveyor belt, causing the conveyor belt and the electric heating tube clamp to reciprocate up and down. The vibrating filling disc is located above the electric heating tube clamp and includes several discharge ports, spring support columns, a sealing cover, and a disc body. The discharge ports are arranged on the disc body, and each discharge port uniquely corresponds to one electric heating tube clamp. The spring support columns are connected below the disc body, and the sealing cover is placed above the disc body. The vibrating filling disc is also connected to a power motor. Since the heating tube clamp is set on the conveyor belt and has an insertion hole, the heating tube is inserted into the insertion hole during implementation. When the heating tube is inserted into the insertion hole and moves to the bottom of the feed port, the guide nozzle is inserted into the heating tube to fill it with material, thereby achieving the function of automatic filling in large batches.

[0005] However, existing heat pipe filling machines still suffer from the technical problem of not being able to quantitatively fill powder. Specifically, the heat pipe powder filling process is a core step in manufacturing sintered heat pipes. Its purpose is to form a uniform capillary wick structure inside the copper tube, laying the foundation for subsequent liquid circulation and heat conduction. Heat pipes typically use high-purity materials, such as 99.5% red copper, which require initial cleaning. This can be done by ultrasonic cleaning with dilute sulfuric acid to remove the oxide layer and impurities from the inner wall of the copper tube, and by checking whether the surface is smooth and burr-free to ensure the adhesion of the copper powder to the tube wall. Some processes also involve shrinking and sealing one end of the copper tube before powder filling to facilitate subsequent operations. After this, powder filling equipment is needed to fill the copper tube with powder. However, in existing technologies, the filling process for heat pipes usually relies on operators to control the amount of filler, which is detrimental to improving filling efficiency in mass production.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Please refer to the following: Figures 1 to 4 This utility model discloses an automatic quantitative powder filling device for heat pipes, comprising: a support frame 1, a lifting mechanism 2, a worktable 3, a feeding mechanism 4, a reciprocating frame 5, a storage bin 6, and a filling part 7; the lifting mechanism 2 is disposed on the side of the support frame 1, and the lifting mechanism 2 is drivenly connected to the worktable 3; the feeding mechanism 4 is disposed at one end of the worktable 3, the reciprocating frame 5 is movably connected to the worktable 3, and the feeding mechanism 4 is drivenly connected to the reciprocating frame 5; the storage bin 6 is connected to the reciprocating frame 5, and the filling part 7 is disposed at the other end of the worktable 3 relative to the feeding mechanism 4, and the storage bin 6 is movably connected to the filling part 7.

[0029] Specifically, when the automatic quantitative powder filling device for heat pipes according to this invention is in operation, the powder to be filled into the heat pipe is pre-loaded into the storage bin 6. External automated conveying fixtures or robotic arms can clamp and limit the heat pipe to be filled and move it below the filling section 7. At this time, the lifting mechanism 2 drives the workbench 3 to descend, causing the filling section 7 to partially insert into the material in the heat pipe to be filled. Next, the feeding mechanism 4 is activated and drives the reciprocating frame 5 to move the storage bin 6 along the limit of the workbench 3 onto the filling section 7. At this time, the powder pre-placed in the storage bin 6 can be guided by the reciprocating frame 5 into the filling section 7, and then introduced into the inner cavity of the heat pipe from the filling section 7. After a preset amount of powder is injected into the inner cavity of the heat pipe, the feeding mechanism 4 drives the reciprocating frame 5 to move the storage bin 6 back until the storage bin 6 is above the filling section 7. At this time, the powder pre-loaded in the storage bin 6 will no longer enter the filling section 7. Then, the lifting mechanism 2 drives the worktable 3 to rise so that the filling section 7 is away from the heat pipe after filling. At this time, the external conveying mechanism can then move the heat pipe after filling away from the filling section 7. Thus, the automatic quantitative powder filling device for heat pipes of this invention can quantitatively fill the heat pipe material with powder pre-stored in the storage bin 6 through the filling section 7, avoiding manual control of the filling amount by the operator. Therefore, the automatic quantitative powder filling device for heat pipes of this invention solves the technical problem of how to improve the filling efficiency of heat pipe filling machines.

[0030] Furthermore, the lifting mechanism 2 includes a lifting cylinder 201, a lifting piston rod 202, and a lifting connecting block 203; the lifting cylinder 201 is connected to the side of the support frame 1, the lifting cylinder 201 is drivenly connected to the lifting piston rod 202, and the lifting connecting block 203 connects the lifting piston rod 202 and the workbench frame 3 respectively.

[0031] Furthermore, the workbench 3 has a balance seat 301, a platform 302, a funnel-shaped material guide channel 303, and a reciprocating guide rail 304; the balance seat 301 is connected to the lifting connecting block 203, the balance seat 301 is disposed at the bottom of the platform 302, the feeding mechanism 4 is disposed at one end of the platform 302, at least one of the funnel-shaped material guide channels 303 is disposed at the other end of the platform relative to the feeding mechanism 4, and the filling part 7 is disposed in the funnel-shaped material guide channel 303; the reciprocating guide rail 304 is disposed on the platform 302.

[0032] Furthermore, the feeding mechanism 4 has a feeding cylinder 401, a feeding piston rod 402, and a feeding connecting arm 403; the feeding cylinder 401 is disposed at one end of the platform 302, the feeding cylinder 401 is drivenly connected to the feeding piston rod 402, and the feeding connecting arm 403 connects the feeding piston rod 402 and the reciprocating seat 5 respectively.

[0033] Furthermore, the reciprocating frame 5 has a reciprocating sliding block 501 and a reciprocating moving seat 502; the reciprocating sliding block 501 is movably disposed in the reciprocating guide rail 304, and one end of the reciprocating sliding block 501 is connected to the feed connecting arm 403; the reciprocating moving seat 502 is connected to the reciprocating sliding block 501, and the storage bin 6 is disposed on the reciprocating moving seat 502.

[0034] Specifically, when the lifting cylinder 201 is activated, it can drive the lifting piston rod 202 to extend or retract, thereby causing the lifting connecting block 203 to rise or fall. When the lifting connecting block 203 rises or falls, the platform 302 can be raised or lowered via the balance seat 301. The balance seat 301 serves two purposes: firstly, it connects the platform 302 and the lifting connecting block 203; secondly, it balances the force, making the lifting and lowering movement of the platform 302 more stable.

[0035] Specifically, when the platform 302 is raised or lowered, the packing portion 7 located in the funnel-shaped material guiding channel 303 at one end can also be raised or lowered accordingly, thereby facilitating the insertion of the packing portion 7 into the cavity of the external heat pipe. More specifically, the packing portion 7 can be a tubular material guiding channel structure, so that the powder falling from the storage bin 6 into the funnel-shaped material guiding channel 303 and then flowing through the packing portion 7 can quickly and accurately fall into the cavity of the heat pipe.

[0036] Specifically, when the feed cylinder 401 is activated, it can drive the feed piston rod 402 to extend or retract, thereby driving the feed connecting arm 403 to move the reciprocating sliding block 501 back and forth along the reciprocating guide rail 304. When the reciprocating sliding block 501 moves, it can drive the reciprocating moving seat 502, so that the storage bin 6, which is mounted on the reciprocating moving seat 502, can be moved by the feed connecting arm 403.

[0037] Furthermore, in another specific embodiment, the reciprocating moving seat 502 has legs 502a, a support platform 502b, an intermediate connecting block 502c, a guide slider 502d, a slider connecting shaft 502e, and a vent 502f; the two legs 502a are arranged parallel to each other, the support platform 502b is disposed on top of the two legs 502a, and the storage bin 6 is disposed on the support platform 502b; the intermediate connecting block 502c is disposed between the two legs 502a, and the intermediate connecting block 502c is disposed between the two legs 502a. Intermediate connecting block 502c connects the reciprocating sliding block 501 and the bearing platform 502b respectively; at least one material guide slider 502d is provided between each support leg 502a and the intermediate connecting block 502c, one end of each material guide slider 502d is connected to the slider connecting shaft 502e, and each slider connecting shaft 502e is connected to the support leg 502a and the intermediate connecting block 502c; at least one ventilation channel 502f is provided on the side of each support leg 502a.

[0038] Furthermore, the storage bin 6 has a storage cylinder 601, a funnel guide part 602, and a discharge pipe 603; the storage cylinder 601 is disposed on the reciprocating moving seat 502, and at least one funnel guide part 602 is provided at the bottom of the storage cylinder 601; the bottom of each funnel guide part 602 is connected to a discharge pipe 603, and each discharge pipe 603 is movably connected to a filling part 7.

[0039] Specifically, when the reciprocating sliding block 501 drives the reciprocating moving seat 502 to position the storage bin 6 at a preset position above the filling part 7, the discharge pipe 603 is connected above the funnel-shaped material guide channel 303. This allows the powder pre-placed in the storage cylinder 601 to enter the discharge pipe 603 along the guidance of the funnel-shaped material guide part 602, and then the discharge pipe 603 guides the powder to the funnel-shaped material guide channel 303. Finally, the funnel-shaped material guide channel 303 transfers the powder to the filling part 7.

[0040] Furthermore, after the heat pipe filling is completed, in order to maintain the performance of precise control of the quantitative filling each time, an external air source device can be connected to the venting channel 502f provided on the side of the support 502a. After the quantitative filling is completed and the heat pipe with the completed filling is removed from below the filling part 7, the external air source introduces high-pressure gas. This high-pressure gas can enter the space between the support 502a and the intermediate connecting block 502c along the venting channel 502f. This is because the venting channel 502f connects the cavity between the two. At this time, the residual powder can be blown off by the high-pressure gas and discharged from the funnel-shaped material guide channel 303 along the guide slider 502d.

[0041] In summary, the automatic quantitative powder filling device for heat pipes of this utility model is provided with a support frame 1, a lifting mechanism 2, a worktable 3, a feeding mechanism 4, a reciprocating frame 5, a storage bin 6, and a filling section 7. The lifting mechanism 2 is arranged on the side of the support frame 1, and the lifting mechanism 2 is drivenly connected to the worktable 3. The feeding mechanism 4 is arranged at one end of the worktable 3, and the reciprocating frame 5 is movably connected to the worktable 3, and the feeding mechanism 4 is drivenly connected to the reciprocating frame 5. The storage bin 6 is connected to the... On the reciprocating frame 5, the filling part 7 is disposed at the other end of the workbench 3 relative to the feeding mechanism 4, and the storage bin 6 is movably connected to the filling part 7; thus, the automatic quantitative powder filling device for heat pipes of this utility model can quantitatively fill the heat pipe material with powder pre-stored in the storage bin 6 through the filling part 7, avoiding manual control of the filling amount by the operator; therefore, the automatic quantitative powder filling device for heat pipes of this utility model solves the technical problem of how to improve the filling efficiency of heat pipe filling machines.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
