Description

Technical Field

[0001] This invention relates to the field of heat sink welding technology, and more specifically to a welding apparatus for heat sink processing. Background Technology

[0002] In the welding process of heat sink processing, accurately positioning and firmly clamping the heat sink is a key step to ensure welding quality. Traditional positioning and clamping methods often have many problems: on the one hand, manual positioning and clamping is inefficient and the positioning accuracy is difficult to guarantee. Differences in operation by different operators can lead to inconsistent positions of the heat sink, affecting the consistency of welding; on the other hand, some simple mechanical positioning devices lack flexibility and cannot adapt to heat sinks of different sizes and shapes, making them inadequate when facing diverse production needs; moreover, during the welding process, the heat sink may shift due to welding stress and other factors, and traditional devices are difficult to effectively prevent this from happening, thus affecting the welding quality. In addition, a lot of heat is generated at the welding point during the heat sink welding process. If the heat cannot be dissipated in time, it will lead to problems such as heat sink deformation and reduced welding quality. Traditional heat dissipation methods are often passive and rely on natural heat dissipation, which is inefficient and cannot meet the needs of high-efficiency welding. Moreover, the stress generated during the welding process will also affect the quality of the heat sink, so certain measures need to be taken to reduce the stress.

[0003] Therefore, in view of this, the present invention proposes a welding apparatus for heat sink processing to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides a welding apparatus for heat sink processing, thereby resolving the corresponding technical issues raised in the background section.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a welding device for heat sink processing, including a worktable, a welding controller installed on the worktable, a welding head installed on the welding controller, and further including: an adjustment limiting mechanism and a follow-up swing mechanism, wherein the adjustment limiting mechanism and the follow-up swing mechanism are both disposed on the worktable; The adjustment and limiting mechanism includes a double-headed bidirectional reciprocating screw, a T-shaped frame, and a positioning plate. The double-headed bidirectional reciprocating screw is disposed on the upper end of the worktable, the T-shaped frame is symmetrically threaded to both ends of the double-headed bidirectional reciprocating screw, and the positioning plate is symmetrically disposed on the upper surface of the worktable. The follow-up swing mechanism includes a placement platform, a take-up reel, a traction rope, and a deflector blades. The placement platform is located at the center of the top of the workbench. The take-up reel is located off-center below the placement platform. The traction rope is wound around the take-up reel. The other end of the traction rope is fixedly connected to one of the positioning plates. The deflector blades are located below the placement platform.

[0006] Preferably, the adjustment limiting mechanism further includes a mounting groove located at the center of the top of the workbench, the T-shaped frame is slidably connected to the mounting groove, the double-headed bidirectional reciprocating screw is rotatably connected to the mounting groove, and a driven wheel is fixedly connected to the outer surface of the front end of the double-headed bidirectional reciprocating screw.

[0007] Preferably, a fixed plate is fixedly connected to the top of the front end of the workbench, and a rotating shaft is rotatably connected through the upper end of the fixed plate. A control lever is fixedly connected to the front side of the rotating shaft, and a drive wheel is fixedly connected to the rear side of the rotating shaft. The drive wheel is meshed with the driven wheel above.

[0008] Preferably, the top two ends of the T-shaped frame are symmetrically fixedly connected with first connecting columns, and the positioning plate is symmetrically provided with notches and slots on both sides. A second connecting column is vertically fixedly connected in the notches and slots, and a connecting plate is rotatably connected between the second connecting column and the first connecting column.

[0009] Preferably, the top of the workbench is provided with symmetrical grooves at both ends, the bottom of the positioning plate is symmetrically fixed with sliders, and the sliders are slidably connected in the grooves. The opposing sides of the positioning plate are fixedly connected with resistance strips.

[0010] Preferably, the follow-up swing mechanism further includes a base fixedly connected between the placement platform and the worktable, a toothed ring rotatably connected to the outer surface of the base, a linkage column fixedly connected coaxially to the inner surface of the winding reel, a torsion spring shaft fixedly connected to the bottom of the linkage column, and the torsion spring shaft rotatably connected to the worktable.

[0011] Preferably, a first gear is fixedly connected to the outer surface of the upper end of the torsion spring shaft, and the first gear meshes with the gear ring.

[0012] Preferably, the upper surface of the workbench is rotatably connected to a driven shaft in a ring shape with the base as the axis. A second gear is fixedly connected to the outer surface of the upper end of the driven shaft, and the second gear meshes with the gear ring. The turbulence blades are fixedly connected to the outer surface of the lower end of the driven shaft.

[0013] Preferably, the placement platform has diversion holes arranged in a ring at equal intervals, and the diameter of the diversion holes near the center of the placement platform decreases from the inside to the outside, and the turbulence blades are arranged below the diversion holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting the adjustment and limiting mechanism, the rotating shaft is driven to rotate by the control lever, which in turn drives the double-headed bidirectional reciprocating screw to rotate, so that the T-shaped frame moves. The positioning plate is driven to move towards each other by the connecting plate, which can quickly push the heat sink in the center and achieve positioning and clamping, greatly improving the efficiency of positioning and clamping, reducing the time and error of manual operation, and thus ensuring the center position of the heat sink on the worktable, making the relative position of the welding head and the heat sink more accurate, which is conducive to improving the precision and quality of welding and ensuring the consistency of the welding point. The resistance strip on the positioning plate increases the resistance between the heat sink and the heat sink, effectively preventing the heat sink from shifting during the welding process, improving the stability of the welding process, and reducing the scrap rate. In addition, the design of the double-headed bidirectional reciprocating screw and the movable positioning plate allows the mechanism to adapt to heat sinks of different sizes, giving it a certain degree of versatility and reducing production costs and equipment replacement frequency.

[0015] (2) By setting the follow-up swing mechanism, while adjusting the operation of the limiting mechanism, the traction rope is driven by the movement of the positioning plate, which in turn causes the torsion spring shaft, the first gear and other components to be linked together, and finally drives the turbulence blades to rotate, actively disturbing the airflow, and transferring the airflow to the surface of the heat sink through the diversion hole, which accelerates the heat dissipation process of the heat sink, effectively reduces the temperature after welding, reduces the deformation caused by heat accumulation and improves the welding quality of the heat sink; The design of the diversion holes reduces the contact area between the heat sink to be welded and the placement platform, thereby reducing the stress generated during welding and helping to improve the structural stability and welding quality of the heat sink. Meanwhile, the design of the air diversion holes being arranged in a ring at equal intervals on the placement platform, with the diameter decreasing from the inside to the outside, allows the airflow to be distributed more evenly on the surface of the heat sink, improving the heat dissipation effect and avoiding problems such as local overheating or uneven heat dissipation. In addition, the follow-up swing mechanism and the adjustment limiting mechanism are also linked, and the heat dissipation function is automatically activated during the process of releasing the positioning clamp heat sink, without the need for additional operation and control, which improves the automation level and work efficiency of the entire welding device.

[0016] (3) The design of the adjustment and limiting mechanism ensures the precise position and stable clamping of the heat sink. The design of the follow-up swing mechanism effectively reduces the influence of welding heat and stress on the heat sink. The two work together to significantly improve the quality and consistency of heat sink welding, reduce manual intervention and operation time, speed up the production cycle, improve production efficiency, and reduce production costs.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Embodiment 1 of the present invention: Please refer to Figures 1 to 6 As shown, a welding device for heat sink processing includes a worktable 1, a welding controller 2 installed on the worktable 1, a welding head 3 installed on the welding controller 2, and also includes an adjustment limiting mechanism 4 and a follow-up swing mechanism 5, wherein the adjustment limiting mechanism 4 and the follow-up swing mechanism 5 are both disposed on the worktable 1. The adjustment limiting mechanism 4 includes a double-headed bidirectional reciprocating screw 406, a T-shaped frame 408, and a positioning plate 411. The double-headed bidirectional reciprocating screw 406 is disposed on the upper end of the worktable 1. The T-shaped frame 408 is symmetrically threaded to both ends of the double-headed bidirectional reciprocating screw 406. The positioning plate 411 is symmetrically disposed on the upper surface of the worktable 1. The adjustment limiting mechanism 4 also includes a mounting groove 405 opened at the center of the top of the workbench 1, a T-shaped frame 408 slidably connected to the mounting groove 405, a double-headed bidirectional reciprocating screw 406 rotatably connected in the mounting groove 405, and a driven wheel 407 fixedly connected to the outer surface of the front end of the double-headed bidirectional reciprocating screw 406. A fixed plate 401 is fixedly connected to the top of the front end of the workbench 1. A rotating shaft 403 is rotatably connected through the upper end of the fixed plate 401. An operating lever 402 is fixedly connected to the front side of the rotating shaft 403. A drive wheel 404 is fixedly connected to the rear side of the rotating shaft 403, and the drive wheel 404 is meshed with the driven wheel 407 above it. The top two ends of the T-shaped frame 408 are symmetrically fixedly connected with first connecting columns 409. The positioning plate 411 has symmetrical notches 413 on both sides. The notches 413 are vertically fixedly connected with second connecting columns 414. The second connecting column 414 and the first connecting column 409 are rotatably connected with a connecting plate 410. The top of the workbench 1 is symmetrically provided with slide grooves 416 at both ends. The bottom of the positioning plate 411 is symmetrically fixedly connected with sliders 415, and the sliders 415 are slidably connected in the slide grooves 416. The opposing sides of the positioning plate 411 are fixedly connected with resistance strips 412.

[0021] Please refer to Figure 3Even better: A ratchet is also fixedly mounted on the outer surface of the rotating shaft 403, and the ratchet is located between the fixed plate 401 and the drive wheel 404. A pawl is rotatably connected to the side of the fixed plate 401 facing the drive wheel 404, and a torsion spring is fixedly connected between the pawl and the fixed plate 401. The pawl and the ratchet cooperate with each other. During the process of controlling the rotation of the rotating shaft 403 and positioning the heat sink through the positioning plate 411, the rotation of the ratchet is not blocked by the pawl. The presence of the pawl can limit the rotation direction of the ratchet, preventing the ratchet from rotating in the opposite direction during the welding process of the heat sink. When the positioning restriction needs to be released after the welding process is completed, the pawl can be moved to twist it away. By releasing the engagement between the ratchet and the pawl, the rotating shaft 403 can be controlled to rotate in the opposite direction, removing the positioning plate 411 from the heat sink's positioning constraint. This allows the heat sink to be removed from the worktable 1 after welding. The engagement between the ratchet and the pawl is existing technology and will not be elaborated on here. The engagement between the ratchet and the pawl makes the positioning operation reversible. After welding, the positioning plate 411 can be easily released from the heat sink's positioning constraint, and the heat sink can be removed. At the same time, the pawl restricts the ratchet's reverse rotation, ensuring the stability of the heat sink's positioning during welding and avoiding positioning failure caused by misoperation.

[0022] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting the adjustment limiting mechanism 4, the rotating shaft 403 is driven to rotate by the control lever 402, which in turn drives the double-headed bidirectional reciprocating screw 406 to rotate, causing the T-shaped frame 408 to move. The connecting plate 410 drives the positioning plate 411 to move towards each other, which can quickly push the heat sink in the center and achieve positioning and clamping, greatly improving the efficiency of positioning and clamping, reducing the time and error of manual operation, and thus ensuring the center position of the heat sink on the worktable 1, making the relative position of the welding head 3 and the heat sink more accurate, which is conducive to improving the precision and quality of welding and ensuring the consistency of the welding points. Among them, the resistance strip 412 set on the positioning plate 411 increases the resistance between it and the heat sink, effectively preventing the heat sink from shifting due to the welding operation during the welding process, improving the stability of the welding process and reducing the scrap rate. In addition, the design of the double-headed bidirectional reciprocating lead screw 406 and the movable positioning plate 411 enables the mechanism to adapt to heat sinks of different sizes, giving it a certain degree of versatility and reducing production costs and equipment replacement frequency.

[0023] Embodiment 2 of the present invention: Please refer to Figures 1 to 6As shown, the follow-up swing mechanism 5 includes a placement platform 502, a winding reel 508, a traction rope 509, and a deflector blade 512. The placement platform 502 is located at the top center of the workbench 1. The winding reel 508 is located off-center below the placement platform 502. The traction rope 509 is wound around the winding reel 508. The other end of the traction rope 509 is fixedly connected to one of the positioning plates 411. The deflector blade 512 is located below the placement platform 502. The follow-up swing mechanism 5 also includes a base 501 fixedly connected between the placement platform 502 and the worktable 1. A toothed ring 504 is rotatably connected to the outer surface of the base 501. A linkage column 507 is coaxially fixedly connected to the inner surface of the winding reel 508. A torsion spring shaft 505 is fixedly connected to the bottom of the linkage column 507, and the torsion spring shaft 505 is rotatably connected to the worktable 1. A first gear 506 is fixedly connected to the outer surface of the upper end of the torsion spring shaft 505, and the first gear 506 is meshed with the gear ring 504. The upper surface of the workbench 1 is rotatably connected to the driven shaft 510 in a ring with the base 501 as the axis. The outer surface of the upper end of the driven shaft 510 is fixedly connected to the second gear 511, and the second gear 511 is meshed with the gear ring 504. The turbulence blade 512 is fixedly connected to the outer surface of the lower end of the driven shaft 510. The placement platform 502 has diversion holes 503 arranged in a ring at equal intervals, and the diameter of the diversion holes 503 near the axis of the placement platform 502 decreases from the inside to the outside. The turbulence blades 512 are arranged below the diversion holes 503.

[0024] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting the follow-up swing mechanism 5, while adjusting the operation of the limiting mechanism 4, the movement of the positioning plate 411 drives the traction rope 509, thereby causing the torsion spring shaft 505, the first gear 506 and other components to move together, and finally drive the turbulence blade 512 to rotate, actively disturbing the airflow, and transferring the airflow to the surface of the heat sink through the diversion hole 503, which accelerates the heat dissipation process of the heat sink, effectively reduces the temperature after welding, reduces problems such as deformation caused by heat accumulation, and improves the welding quality of the heat sink; The design of the diversion hole 503 reduces the contact area between the heat sink to be welded and the placement platform 502, thereby reducing the stress generated during welding and helping to improve the structural stability and welding quality of the heat sink. Meanwhile, the air diversion holes 503 are arranged in a ring at equal intervals on the placement platform 502, and the diameter decreases from the inside to the outside. This design allows the airflow to be distributed more evenly on the surface of the heat sink, improving the heat dissipation effect and avoiding the problems of local overheating or uneven heat dissipation. In addition, the follow-up swing mechanism 5 and the adjustment and limiting mechanism 4 are also linked, and the heat dissipation function is automatically activated during the process of releasing the positioning clamp on the heat sink, without the need for additional operation and control, which improves the automation level and work efficiency of the entire welding device.

[0025] The complete usage steps and working principle of the above embodiments are as follows: It should be noted in advance that, if Figure 1 As shown, a welding controller 2 is vertically upward at the rear end of the workbench 1, and a welding head 3 is located at the lower front end of the welding controller 2. A placement platform 502 is located at the center of the upper surface of the workbench 1 for placing the heat sink to be welded. The welding head 3 is located directly above the placement platform 502, and the axis of the welding head 3 and the center of the placement platform 502 are initially on the same vertical axis. In use, the welding head 3 can be controlled by the welding controller 2 to weld the heat sink to be welded placed on the placement platform 502 below it. It should also be noted that the above are all existing technologies and will not be elaborated on here.

[0026] The following is the working process of adjusting and limiting mechanism 4 to position the heat sink to be welded: Before welding the heat sink, the operator can first place the heat sink on the upper surface of the placement platform 502, referring to... Figure 2 and Figure 3 As shown, a fixed plate 401 is fixedly installed at the front end of the workbench 1, and a rotating shaft 403 is rotatably mounted through the fixed plate 401. One end of the rotating shaft 403 is connected to a control lever 402, and the other end is connected to a drive wheel 404. After the heat sink is placed, the operator can control the rotating shaft 403 to rotate on the fixed plate 401 by operating the control lever 402, which simultaneously drives the drive wheel 404 to rotate around the rotating shaft 403 as the axis above the driven wheel 407. Figure 3 As shown, a mounting groove 405 is provided in the middle of the upper end of the workbench 1, and a double-headed bidirectional reciprocating screw 406 is rotatably mounted in the mounting groove 405. A driven wheel 407 is fixedly mounted on the outer surface of the front end of the double-headed bidirectional reciprocating screw 406, and is meshed below the drive wheel 404. Therefore, when the operator operates the control lever 402 to rotate the drive wheel 404, the meshing relationship between the drive wheel 404 and the driven wheel 407 below it drives the driven wheel 407 to rotate synchronously around the double-headed bidirectional reciprocating screw 406 as its axis at the front end of the mounting groove 405, thereby driving the double-headed bidirectional reciprocating screw 406 to rotate synchronously between the two sides of the mounting groove 405. Figure 4As shown, since the outer surfaces of both ends of the double-headed bidirectional reciprocating screw 406 are symmetrically threaded with T-shaped brackets 408, and the top ends of the T-shaped brackets 408 are symmetrically provided with first connecting posts 409, a set (two) of positioning plates 411 for positioning the heat sink to be welded are symmetrically slidably arranged on the worktable 1 through the sliding cooperation of the sliding groove 416 and the slider 415. The positioning plates 411 have symmetrical notches 413 on both sides, and the second connecting post 414 is vertically fixed in the notch 413. The connecting plate 410 is rotatably arranged between the second connecting post 414 and the first connecting post 409. Therefore, when the double-headed bidirectional reciprocating screw 406 is symmetrically threaded with T-shaped brackets 408, and the top ends of the T-shaped brackets 408 are symmetrically provided with first connecting posts 409, the double-headed screw 406 can be symmetrically slidably arranged on the worktable 1. When the bidirectional reciprocating screw 406 rotates, it can drive the two T-shaped frames 408 to move in opposite directions on the worktable 1 through the threaded engagement with the T-shaped frame 408. At this time, the connecting plate 410 can drive the two positioning plates 411 to move towards each other on the worktable 1 synchronously, and push the heat sink to be welded placed between the two positioning plates 411 (i.e., on the upper surface of the placement platform 502) in the center, and realize the positioning and clamping of the heat sink, and fix it firmly on the worktable 1, so that it can be welded by the welding head 3 in the future. according to Figure 4 As shown, resistance strips 412 are fixedly installed on the opposing sides of the positioning plates 411. When the two positioning plates 411 move towards each other to position the heat sink to be welded, the resistance strips 412 will preferentially contact the outer surface of the heat sink. Through the intervention of the resistance strips 412 between the heat sink and the positioning plates 411, the resistance between the positioning plates 411 and the heat sink can be increased, avoiding the heat sink from shifting due to welding operations during subsequent welding processes. This can further improve the stability of the heat sink welding process and greatly improve the quality and efficiency of the welding process. It should also be noted that a ratchet is fixedly mounted on the outer surface of the rotating shaft 403, and the ratchet is located between the fixed plate 401 and the drive wheel 404. A pawl is rotatably connected to the side of the fixed plate 401 facing the drive wheel 404, and a torsion spring is fixedly connected between the pawl and the fixed plate 401. The pawl and the ratchet cooperate with each other. During the process of controlling the rotation of the rotating shaft 403 and positioning the heat sink through the positioning plate 411, the rotation of the ratchet is not blocked by the pawl. The presence of the pawl can limit the rotation direction of the ratchet, preventing the ratchet from rotating in the opposite direction during the welding process of the heat sink. When the positioning restriction needs to be released after the welding process is completed, the pawl can be moved to twist it away. By opening the surface of the ratchet and releasing the engagement between it, the rotating shaft 403 can be controlled to rotate in the reverse direction, removing the positioning plate 411 from the positioning restriction of the heat sink, so that the heat sink after welding can be removed from the worktable 1. The engagement relationship between the ratchet and the pawl is existing technology and will not be elaborated on here. The engagement between the ratchet and the pawl makes the positioning operation reversible. After welding, the positioning restriction of the positioning plate 411 on the heat sink after welding can be easily released and the heat sink can be removed. At the same time, the pawl restricts the reverse rotation of the ratchet, ensuring the stability of the heat sink positioning during the welding process and avoiding positioning failure caused by misoperation. Based on this, the adjustable limiting mechanism 4 is set up, and the rotating shaft 403 is driven to rotate by the control lever 402, which in turn drives the double-headed bidirectional reciprocating screw 406 to rotate, so that the T-shaped frame 408 moves. The connecting plate 410 drives the positioning plate 411 to move towards each other, which can quickly push the heat sink in the center and achieve positioning and clamping, which greatly improves the efficiency of positioning and clamping, reduces the time and error of manual operation, and ensures the center position of the heat sink on the worktable 1, so that the relative position of the welding head 3 and the heat sink is more accurate, which is conducive to improving the precision and quality of welding and ensuring the consistency of welding points. Among them, the resistance strip 412 set on the positioning plate 411 increases the resistance between it and the heat sink, effectively preventing the heat sink from shifting due to the welding operation during the welding process, improving the stability of the welding process and reducing the scrap rate. In addition, the design of the double-headed bidirectional reciprocating screw 406 and the movable positioning plate 411 enables the mechanism to adapt to heat sinks of different sizes, giving it a certain degree of versatility and reducing production costs and equipment replacement frequency. Please refer to the above work process. Figures 1 to 6 .

[0027] The following describes the working process of the follow-up swing mechanism 5 synchronously disturbing the airflow during the operation of the adjustment and limiting mechanism 4: During the process of positioning the heat sink to be welded on the placement platform 502 by moving the two positioning plates 411 above the worktable 1 towards each other, such as... Figure 5 and Figure 6 As shown, a base 501 is fixedly installed between the bottom of the placement platform 502 and the worktable 1, and a toothed ring 504 is rotatably installed on the outer surface of the base 501. (Refer to...) Figure 2 As shown, a traction rope 509 is fixedly connected to the inner side of one of the positioning plates 411. The other end of the traction rope 509 is wound around a take-up reel 508. A linkage column 507 is coaxially and fixedly connected to the inner surface of the take-up reel 508. A torsion spring shaft 505 is fixedly connected to the bottom of the linkage column 507. When initially unused, the further the positioning plate 411 is from the center of the worktable 1, the greater the torsional force of the torsion spring shaft 505. Therefore, when the positioning plate 411 moves closer to the center of the worktable 1 (i.e., when the two positioning plates 411 move towards each other to position the heat sink), the torsion spring shaft 505 is utilized. The traction rope 509 experiences a reverse tension, causing its outward stretching force to gradually decrease. Consequently, the external torsional force on the torsion spring shaft 505 also gradually decreases, allowing it to rotate in the opposite direction on the worktable 1. Since the first gear 506 is fixedly mounted on the upper outer surface of the torsion spring shaft 505 and meshes with the outer surface of the gear ring 504, the rotation of the torsion spring shaft 505 enables the first gear 506 to rotate synchronously around the torsion spring shaft 505. It should be noted that the winding reel 508... The linkage column 507, the first gear 506, and the torsion spring shaft 505 are interconnected to form an integral structure, which is rotatably mounted on the worktable 1. Therefore, the approach of the positioning plate 411 can drive this entire structure to rotate synchronously on the worktable 1. Utilizing the meshing relationship between the teeth of the first gear 506 and the gear ring 504, the gear ring 504 can be synchronously driven to rotate on the outer surface of the base 501 as the positioning plate 411 approaches. Furthermore, because the outer surface of the gear ring 504 is equidistantly distributed with second gears 511 in a ring shape, and the second gears 511 are also connected to... The gear ring 504 is meshed and connected. A driven shaft 510 is fixedly mounted coaxially on the inner surface of the second gear 511. The outer surface of the lower end of the driven shaft 510 is also fixedly mounted with eccentrically spaced turbulence blades 512 in an annular shape. Therefore, when the first gear 506 drives the gear ring 504 to rotate around the base 501, the meshing between the teeth of the first gear 506 and the second gear 511 can drive the second gear 511 to rotate synchronously around the driven shaft 510. This will drive the driven shaft 510 to rotate synchronously with the turbulence blades 512 mounted at its lower end, thus disturbing the airflow in the vicinity. according to Figure 5As shown, the placement platform 502 has equidistant, annular diversion holes 503 on its outer ring. The diameter of the diversion holes 503 decreases sequentially from the innermost ring to the outermost ring, with the outermost holes having the smallest diameter and the innermost holes having the largest diameter. The baffle blades 512 are positioned below the placement platform 502 in the gap between the platform and the base 501. When the baffle blades 512 rotate, they can agitate the surrounding airflow and... The airflow is transmitted through the diversion hole 503 to the surface of the heat sink placed on the upper surface of the placement platform 502. The opening design of the diversion hole 503 not only reduces the contact between the heat sink to be welded and the placement platform 502 and reduces the stress generated during welding, but also allows the airflow to pass through after the welding process. The positioning plate 411 makes the positioning contact, and simultaneously causes the traction rope 509 to pull the winding reel 508 to rotate in the opposite direction, still controlling the turbulence blades 512 to rotate and turbulent, thereby promoting the reduction of the heat sink temperature after welding. Based on this, by setting the follow-up swing mechanism 5, while adjusting the operation of the limiting mechanism 4, the movement of the positioning plate 411 drives the traction rope 509, which in turn causes the torsion spring shaft 505, the first gear 506 and other components to be linked together, ultimately driving the turbulence blade 512 to rotate, actively disturbing the airflow, and transferring the airflow to the surface of the heat sink through the diversion hole 503, which accelerates the heat dissipation process of the heat sink, effectively reduces the temperature after welding, reduces problems such as deformation caused by heat accumulation, and improves the welding quality of the heat sink; The design of the diversion hole 503 reduces the contact area between the heat sink to be welded and the placement platform 502, thereby reducing the stress generated during welding and helping to improve the structural stability and welding quality of the heat sink. Meanwhile, the air diversion holes 503 are arranged in a ring at equal intervals on the placement platform 502, and the diameter decreases from the inside to the outside. This design allows the airflow to be distributed more evenly on the surface of the heat sink, improving the heat dissipation effect and avoiding the problems of local overheating or uneven heat dissipation. In addition, the follow-up swing mechanism 5 and the adjustment and limiting mechanism 4 are also linked, and the heat dissipation function is automatically activated during the process of releasing the positioning clamp heat sink, without the need for additional operation and control, which improves the automation level and work efficiency of the entire welding device. Please refer to the above work process. Figures 1 to 6 .

[0028] In summary, the design of the adjusting and limiting mechanism 4 ensures the precise position and stable clamping of the heat sink, while the design of the follow-up swing mechanism 5 effectively reduces the impact of welding heat and stress on the heat sink. The combined effect of these two mechanisms significantly improves the quality and consistency of heat sink welding, reduces manual intervention and operation time, speeds up the production cycle, increases production efficiency, and reduces production costs.
