Description

Technical Field

[0001] The invention belongs to the technical field of radiator fin welding assembly, in particular to a radiator fin welding assembly device. Background Art

[0002] Radiator fin welding assembly equipment is designed for efficient thermal management. The equipment integrates copper tube precision plug-in and automated welding technology to ensure the perfect combination of copper tube and fin, greatly improving the heat exchange efficiency. Through high-precision controlled production, it provides excellent heat dissipation performance for electronic equipment. Now, radiator fins are usually produced by using radiator fin welding assembly equipment.

[0003] Before using the existing radiator fin welding equipment, the copper tube and the heat sink fin are first plugged and assembled. A number of sockets are opened inside the heat sink fin, and the "U"-shaped copper tubes need to be plugged into these sockets before the heat sink can be dissipated. However, when plugging the "U"-shaped copper tube, the "U"-shaped copper tube needs to be checked first to ensure that there is no foreign matter inside, and then the end of the copper tube is aligned with the socket of the heat sink fin, and then the copper tube is gently pushed into the socket of the heat sink fin. A certain amount of force needs to be applied during this process, but excessive force should be avoided to damage the socket and the copper tube. If the socket is tight, an appropriate amount of lubricant needs to be applied to assist in the plugging of the copper tube. After the copper tube is completed, After the assembly with the heat sink fins, the radiator fins are welded by a welding torch head to complete the processing and production of the radiator fins. However, during the assembly of the copper tubes and the heat sink fins, the copper tube plugging process is too cumbersome, resulting in the problem of low production efficiency of the radiator fins. At the same time, if lubricants are used for lubrication during the copper tube plugging process, these residual lubricating oil stains will affect the welding quality, because the oil stains will decompose at high temperatures to produce gases and impurities. These gases and impurities are easy to form defects such as pores and slag inclusions in the weld, thereby reducing the strength and sealing of the weld, so that the heat dissipation effect of the produced radiator fins is poor, resulting in the problem of poor quality of the produced radiator fins.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0040] like Figures 1 to 11 As shown, a radiator fin welding assembly device described in an embodiment of the present invention includes a support table 1, a first guide rail 11 is provided on the upper surface of the support table 1, a first guide block 12 is slidably connected inside the first guide rail 11, a clamping assembly is arranged inside the first guide block 12, a heat dissipation fin 13 is provided on the upper surface of the first guide block 12, a plurality of jacks 14 are provided on the upper surface of the heat dissipation fin 13, the heat dissipation fin 13 is clamped by the clamping assembly inside the first guide block 12, a fixing box 4 is fixedly connected to the upper surface of the support table 1, an assembly assembly is arranged in the fixing box 4, the assembly assembly is used for automatically plugging in the copper tube 2, a welding table 15 is fixedly connected to one side of the support table 1, a plurality of welding flame heads 16 are fixedly connected to both sides of the inner wall of the welding table 15, the plurality of welding flame heads 16 are used for welding the copper tube 2 and the heat dissipation fin 13, a plurality of transmission rollers 17 are rotatably arranged on the bottom surface of the welding table 15, and the plurality of transmission rollers 17 are used for transmitting the assembled radiator fins.

[0041] Specifically, before using the existing radiator fin welding equipment, the copper tube 2 and the heat dissipation fin 13 are first plugged and assembled. A plurality of plug holes 14 are opened inside the heat dissipation fin 13, and the "U"-shaped copper tube 2 needs to be plugged into these plug holes 14 before the heat dissipation effect can be achieved. However, when plugging the "U"-shaped copper tube 2, it is necessary to first check the "U"-shaped copper tube 2 to ensure that there is no foreign matter inside, and then align the end of the copper tube 2 with the plug of the heat dissipation fin 13, and then gently push the copper tube 2 into the heat dissipation fin 13. In the socket of the fin 13, a certain force needs to be applied during this process, but excessive force should be avoided to damage the socket and the copper tube 2. If the socket is tight, an appropriate amount of lubricant needs to be applied to assist the insertion of the copper tube 2. After the copper tube 2 and the heat dissipation fin 13 are assembled, the welding of the welding torch 16 is performed to complete the processing and production of the radiator fin. However, during the assembly of the copper tube 2 and the heat dissipation fin 13, the insertion process of the copper tube 2 is too cumbersome, resulting in the problem of low production efficiency of the radiator fin.

[0042] Therefore, the present invention solves this problem by setting a certain structure. First, when using the device, the heat dissipation fin 13 is placed on the upper surface of the first guide block 12, and then clamped by the clamping assembly in the first guide block 12, and the first guide block 12 is started to slide along the first guide rail 11. After the first guide block 12 slides, it will drive the heat dissipation fin 13 to move to the bottom of the assembly assembly, and then the copper tube 2 is inserted into the slot of the heat dissipation fin 13 by starting the assembly assembly, and then the first guide block 12 is moved section by section, so that the copper tube 2 is inserted into each slot on the upper surface of the heat dissipation fin 13. After the copper tube 2 and the heat sink fin 13 complete the assembly of the radiator fin, the first guide block 12 will drive the radiator fin to move to the welding table 15, and then the radiator fin will be placed on the transmission roller 17 through the first guide block 12, and then the clamping assembly releases the radiator fin, and the transmission roller 17 will drive the radiator fin to pass through a number of welding flame heads 16 for welding. Through the setting of the assembly assembly, the assembly time with the heat sink fin 13 can be reduced, the assembly process is simplified, and the efficiency of welding assembly is improved to a certain extent through automated assembly, thereby improving the production efficiency of welding assembly;

[0043] The problem that the plugging process of the copper tube 2 is too complicated during the assembly of the copper tube 2 and the heat dissipation fins 13, thereby causing low production efficiency of the radiator fins, is solved.

[0044] like Figure 8As shown, the clamping assembly of this embodiment includes two first guide blocks 12, the inner wall of the first guide block 12 is provided with a first groove body 121, the inner wall of the first groove body 121 is fixedly connected with an electric permanent magnet block, the inner wall of the first groove body 121 is fixedly connected with a plurality of compression springs 122, one end of the plurality of compression springs 122 away from the inner wall of the first groove body 121 is fixedly connected with the same magnetic block 123, and the bottom wall of the first guide block 12 is provided with a pressure sensor 124.

[0045] Specifically, after the heat sink 13 is placed on the first guide block 12, the lower surface of the heat sink 13 will squeeze the pressure sensor 124 on the first guide block 12. After the pressure sensor 124 senses the pressure signal, the electric permanent magnet block on the inner wall of the first slot body 121 is powered off. The electric permanent magnet block after power failure will lose its magnetic attraction with the magnetic block 123, and then the compression spring 122 between the magnetic block 123 and the inner wall of the first slot body 121 will be released. The compression spring 122 on each side will drive the magnetic block 123 to squeeze, clamp and limit the heat sink 13, thereby achieving the effect of stabilizing and fixing the heat sink 13, and then the copper tube 2 can be stably plugged in.

[0046] like Figure 6 As shown, the assembly component of this embodiment includes a first cavity 41 opened in the fixed box 4, a middle partition 42 is fixedly connected to the middle of the first cavity 41, and a plurality of copper tubes 2 are mounted on the middle partition 42. Second guide rails 43 are fixedly connected to both sides of the inner wall of the first cavity 41, and a movable plate 44 is slidably connected in each second guide rail 43, and a plurality of telescopic plates 45 are slidably connected to one side of each movable plate 44, and a drop groove 46 is opened on one side of the fixed box 4.

[0047] Specifically, before using the assembly components for assembly, firstly, several copper tubes 2 are placed on the middle partition plate 42 in the fixed box 4, because the cross section of the copper tube 2 is "U"-shaped, and then by starting the movable plates 44 on both sides of the middle partition plate 42, the movable plates 44 will extend several telescopic plates 45, and the spacing between every two telescopic plates 45 is fixed, just enough to place a copper tube 2, and the outer layer of several telescopic plates 45 is covered with a layer of rubber sleeve, but the telescopic plates 45 close to the drop groove 46 are not covered with a rubber sleeve on the side close to the drop groove 46, because after the telescopic plates 45 separate the several copper tubes 2, by starting The second guide rail 43 drives the movable plate 44 to slide, and then the telescopic plate 45 arranged near the discharge chute will push the copper tube 2 into the discharge chute, and then it can fall into the socket 14 of the heat dissipation fin 13 through the guidance of the discharge chute, thereby completing the assembly of a copper tube 2, thereby achieving the effect of automatic assembly, and then the telescopic plate 45 is retracted into the movable plate 44, and the movable plate 44 is reset by the second guide rail 43. After the movable plate 44 is reset, the telescopic plate 45 is started again to separate the copper tubes 2, thereby achieving the effect of continuous automatic assembly, improving the production efficiency of welding assembly, and saving a certain amount of production cost.

[0048] like Figure 6 and Fig.10 As shown, in this embodiment, one side of the drop groove 46 is fixedly connected to a limit plate 47 , one side of the limit plate 47 is adapted to the “U”-shaped copper tube 2 , and a lubrication component is provided on the upper surface of the fixed box 4 , which is used to lubricate the limit plate 47 .

[0049] Specifically, by fixing a limit plate 47 on one side of the drop groove 46, when the telescopic plate 45 pushes one of the copper tubes 2 into the feed groove, the limit plate 47 will fit with the copper tube 2, thereby preventing the copper tube 2 from shaking during the falling process, thereby preventing the copper tube 2 from deviating and being unable to be inserted into the heat sink plug hole 14, thereby improving the assembly quality and the assembly efficiency.

[0050] like Fig.10 As shown, the lubrication assembly of this embodiment includes a sliding guide rail 5 fixedly connected to the upper surface of the fixed box 4, a sliding groove 51 is opened on one side of the sliding guide rail 5, a sliding rod 52 is slidably connected in the sliding groove 51, an insert plate 53 is fixedly connected to the lower surface of the sliding rod 52, and a connecting box 54 is fixedly connected to the upper surface of the sliding rod 52.

[0051] Specifically, in the process of using the limit plate 47 for limiting, it is necessary to apply a certain amount of lubricant to the circular axis surface of the copper tube 2. Therefore, before pushing the copper tube 2 down each time, the sliding guide rail 5 on the fixed box 4 is started. After the sliding guide rail 5 is started, it drives the sliding rod 52 to slide along the sliding groove 51. The sliding of the sliding rod 52 can drive the plug plate 53 fixed on the lower surface of the sliding rod 52 to be inserted into the limit plate 47. The plug plate 53 fits with the limit plate 47, thereby achieving the effect of automatically applying the lubricant, and then it can assist the copper tube 2 to be inserted into the heat dissipation fin 13, thereby improving the quality of assembly.

[0052] like Figure 6 and Figure 7 As shown, in this embodiment, two fixed blocks 49 are fixedly connected to one side of the drop groove 46, and a rotating shaft 410 is rotatably connected between the two fixed blocks 49. A limiting rod 48 is sleeved on the circumferential surface of the rotating shaft 410, and torsion springs 411 are fixedly connected to both sides of the limiting rod 48. The two torsion springs 411 are sleeved on both ends of the rotating shaft 410.

[0053] Specifically, after the copper tube 2 falls to the bottom of the feeding chute, the limit rod 48 rotatably connected to one side of the feeding chute will be inserted into the empty part in the middle of the copper tube 2. Then, when the top end of the copper tube 2 falls to the limit plate 47, the limit rod 48 will be driven to rotate due to gravity. After the limit rod 48 rotates, the copper tube 2 will fall, thereby achieving the effect of stable falling of the copper tube 2.

[0054] like Fig.10As shown, in this embodiment, a soft cloth is fixedly connected to one side of the plug plate 53 close to the limit plate 47 , and a plurality of holes are opened inside the plug plate 53 , and the plurality of holes are used to flow out the lubricating oil in the connection box 54 .

[0055] Specifically, a soft cloth is fixed to the plug board 53. When the plug board 53 is used to apply lubricant, the lubricating oil in the connecting box 54 penetrates into the soft cloth of the plug board 53, and then the soft cloth can coat the limit plate 47, so that the limit plate 47 can not only increase the smoothness of falling, but also improve the stability of the copper tube 2 inserted into the heat sink 13. Embodiment 2

[0056] like Figures 2 to 11 As shown, comparative example 1, wherein another embodiment of the present invention is: a storage box 3 is fixedly connected to one side of a fixed box 4, a pressure pump 31 is fixedly connected to the upper surface of the storage box 3, a connecting pipe 33 is fixedly connected to the lower surface of the storage box 3, a fixed frame 34 is fixedly connected to the lower surface of the fixed box 4, the fixed frame 34 is fixedly connected to the storage box 3 via the connecting pipe 33, two nozzles 35 are fixedly connected to the lower surface of the fixed frame 34, a plurality of nozzles are provided on the side where the two nozzles 35 are close to each other, the nozzles are used to spray out acid cleaning agent, and the two nozzles 35 are located on both sides of the heat dissipation fins 13, a sealing cover 32 is threadedly connected to the upper surface of the storage box 3, and the sealing cover 32 is used to add acid cleaning agent.

[0057] Specifically, if lubricant is used for lubrication during the insertion of the copper tube 2, the residual lubricating oil will affect the welding quality, because the oil will decompose at high temperature to produce gas and impurities, and these gases and impurities are likely to form defects such as pores and slag inclusions in the weld, thereby reducing the strength and sealing of the weld, so that the heat dissipation effect of the produced radiator fins is poor, resulting in the problem of poor quality of the produced radiator fins;

[0058] Therefore, the present invention cleans the end of the copper tube 2 after lubrication and plugging by setting a certain structure, and removes the lubricating oil stains remaining at the end thereof. First, the pressure pump 31 on the storage box 3 is started. After the pressure pump 31 is started, the acid cleaning agent in the storage box 3 will be pressurized, and the acid cleaning agent will be pressurized into the connecting pipe 33, and then sprayed out through the nozzle 35 on the lower surface of the fixed frame 34. The acid cleaning agent sprayed by the nozzle 35 will fall on the arc-shaped end of the copper tube 2, thereby cleaning the lubricating oil stains attached to the surface of the copper tube 2, because the acid cleaning agent reacts chemically with dirt, grease, oxides, etc. through the acidic substances it contains, and decomposes them into substances that are easy to clean, thereby achieving the purpose of decontamination, improving the subsequent welding quality, making the welding quality higher, thereby ensuring the heat dissipation effect of the radiator fins.

[0059] like Fig. 9As shown, two cleaning brushes 36 are fixedly connected to the lower surface of the fixing frame 34 of this embodiment, and a plurality of brushes are fixedly connected to the side of the two cleaning brushes 36 close to each other. The plurality of brushes are used to clean the acid cleaning agent remaining on the upper surface of the radiator fins.

[0060] Specifically, after the acidic cleaning agent decomposes the lubricating oil, the arc-shaped part of the copper tube 2 is cleaned by two cleaning brushes 36 on the lower surface of the fixed frame 34, so as to clean up the substances decomposed by the acidic cleaning agent, prevent problems such as welds that may be generated during the welding process, and achieve the effect of improving the welding quality.

[0061] like Figure 4 As shown, in this embodiment, a first hydraulic cylinder 6 is fixedly connected to one side of the fixed box 4 , a pressure plate 61 is fixedly connected to the output end of the first hydraulic cylinder 6 , and the pressure plate 61 is made of hard rubber. A photoelectric sensor 62 is fixedly connected to the lower surface of the fixed box 4 .

[0062] Specifically, after cleaning the copper tube 2 of the radiator fin, there may be a certain height deviation in the process of the copper tube 2 automatically being inserted into the heat dissipating fin 13. Therefore, when passing through the photoelectric sensor 62 on the lower surface of the fixed box 4, the photoelectric sensor 62 will receive a signal, and then the first hydraulic cylinder 6 will be started to drive the pressure plate 61 at its output end to gently press down to the standard. Each copper tube 2 is corrected in position, thereby achieving the effect of producing radiator fins with higher quality.

[0063] Working principle: first, when using the device, the heat dissipation fin 13 is placed on the upper surface of the first guide block 12. After the heat dissipation fin 13 is placed on the first guide block 12, the lower surface of the heat dissipation fin 13 will squeeze the pressure sensor 124 on the first guide block 12. After the pressure sensor 124 senses the pressure signal, the electric permanent magnet block on the inner wall of the first slot body 121 is powered off. After the power is off, the electric permanent magnet block loses the magnetic attraction with the magnetic block 123. Then, the compression spring 122 between the magnetic block 123 and the inner wall of the first slot body 121 is released. The compression spring 122 on each side will drive the magnetic block 123 to squeeze, clamp and limit the heat dissipation fin 13, thereby achieving the effect of stably fixing the heat dissipation fin 13. Then, the copper tube 2 can be stably plugged in, and then the first guide block 12 is started to slide along the first guide rail 11. After the first guide block 12 slides, it will drive the heat dissipation fin 13 to move to the bottom of the assembly component.

[0064] Then, by starting the assembly component, before using the assembly component for assembly, first, several copper tubes 2 are placed on the middle partition plate 42 in the fixed box 4, because the cross section of the copper tube 2 is "U" shaped, and then by starting the movable plates 44 on both sides of the middle partition plate 42, the movable plates 44 will extend several telescopic plates 45, and the spacing between every two telescopic plates 45 is fixed, just enough to place a copper tube 2, and the outer layer of several telescopic plates 45 is covered with a layer of rubber sleeve, but the telescopic plates 45 close to the drop groove 46 are not covered with a rubber sleeve on the side close to the drop groove 46, because when the telescopic plates 45 separate the several copper tubes 2, through By starting the second guide rail 43 to drive the moving plate 44 to slide, the telescopic plate 45 arranged near the feeding chute will push the copper tube 2 into the feeding chute, and then it can fall into the jack 14 of the heat dissipation fin 13 through the guidance of the feeding chute, thereby completing the assembly of a copper tube 2, thereby achieving the effect of automatic assembly, and then the telescopic plate 45 is retracted into the moving plate 44, and the moving plate 44 is driven to reset by the second guide rail 43. After the moving plate 44 is reset, the telescopic plate 45 is started again to separate the copper tubes 2, thereby achieving the effect of continuous automatic assembly, improving the production efficiency of welding assembly, and saving a certain amount of production cost;

[0065] In addition, by fixing a limit plate 47 on one side of the drop groove 46, when the telescopic plate 45 pushes one of the copper tubes 2 into the feed groove, the limit plate 47 will fit with the copper tube 2, thereby preventing the copper tube 2 from shaking during the falling process, thereby preventing the copper tube 2 from deviating and being unable to be inserted into the heat sink plug hole 14, improving the assembly quality and improving the assembly efficiency. At the same time, in the process of using the limit plate 47 for limiting, it is necessary to apply a certain amount of lubricant to the circular axis surface of the copper tube 2. Therefore, before pushing the copper tube 2 to fall each time, the sliding guide rail 5 on the fixed box 4 is started. After the sliding guide rail 5 is started, the sliding rod 52 is driven to slide along the sliding groove 51. The sliding of the sliding rod 52 can drive the plug plate 53 fixed on the lower surface of the sliding rod 52 to be inserted into the limit plate 47, and the plug plate 53 fits with the limit plate 47, thereby achieving the effect of automatically applying the lubricant, and then the copper tube 2 can be assisted to be inserted into the heat sink fin 13, thereby improving the assembly quality.

[0066] However, these residual lubricating oil stains will affect the welding quality, because the oil stains will decompose at high temperatures to produce gases and impurities, and these gases and impurities are easy to form defects such as pores and slag inclusions in the weld, thereby reducing the strength and sealing of the weld, resulting in poor heat dissipation effect of the produced radiator fins, resulting in the problem of poor quality of the produced radiator fins. Therefore, during the assembly process, the pressure pump 31 on the storage box 3 is started. After the pressure pump 31 is started, the acid cleaning agent in the storage box 3 will be pressurized, and the acid cleaning agent will be pressurized into the connecting pipe 33, and then sprayed out through the nozzle 35 on the lower surface of the fixed frame 34, and the acid cleaning agent sprayed by the nozzle 35 will fall on the copper tube 2. The arc-shaped end of the copper tube 2 is cleaned, because the acidic cleaning agent reacts chemically with dirt, grease, oxides, etc. through the acidic substances contained in it, decomposing them into substances that are easy to clean, thereby achieving the purpose of decontamination, improving the subsequent welding quality, making the welding quality higher, thereby ensuring the heat dissipation effect of the radiator fins, and after the acidic cleaning agent decomposes the lubricating oil, the arc-shaped part of the copper tube 2 is cleaned by two cleaning brushes 36 on the lower surface of the fixed frame 34, so that the substances decomposed by the acidic cleaning agent are cleaned, preventing problems such as welds that may occur during the welding process, and achieving the effect of improving the welding quality;

[0067] Finally, after cleaning the copper tube 2 of the radiator fin, there may be a certain height deviation in the process of the copper tube 2 automatically inserting into the radiator fin 13. Therefore, when passing through the photoelectric sensor 62 on the lower surface of the fixed box 4, the photoelectric sensor 62 will receive a signal, and then the first hydraulic cylinder 6 will be started to drive the pressure plate 61 at its output end to gently press down to the standard. Each copper tube 2 is corrected in position, achieving the effect of being able to produce higher quality radiator fins.

[0068] Then the first guide block 12 will drive the radiator fin to move to the welding table 15, and then the radiator fin will be placed on the transmission roller 17 through the first guide block 12, and then the clamping assembly will release the radiator fin, and the transmission roller 17 will drive the radiator fin to pass through several welding flame heads 16 for welding. Through the setting of the assembly assembly, the assembly time with the heat sink fin 13 can be reduced, the assembly process is simplified, and through automated assembly, the efficiency of welding assembly is improved to a certain extent, thereby improving the production efficiency of welding assembly.
