[0025] A double-sided weld system for heat sinks: In one specific embodiment, it includes: The base 100 is provided with a conveying assembly for conveying the corrugated sheet 200; The positioning component is installed on the conveying component, and its top end is inserted into the bottom end of the corrugated plate 200's inner cavity of the corrugated plate. Two clamping components are symmetrically arranged at intervals and are rotatably connected to the outer wall of the base 100; A transmission component is mounted on the base 100 and is capable of driving the clamping component to clamp or release the corrugated sheet 200. The bracket 300 is fixedly connected to the clamping assembly; The lifting assembly is mounted on the bracket 300, and its lifting end is equipped with a welding assembly; A clamping assembly is mounted on the bracket 300 and is capable of clamping or releasing the end of the lobe; The cooling component is mounted on the clamping assembly.

[0026] This system can automatically convey materials, position and clamp them, weld and cool them. All components work together to complete the processing of corrugated sheet welds. The automated operation mode eliminates manual welding, which reduces labor intensity and can unify welding quality. At the same time, the cooling components remove the welding heat and prevent the workpiece from thermally deforming.

[0027] In one specific embodiment, reference is made to Figures 3 to 6 As shown, the conveying assembly includes a rotating shaft 700, a rotating wheel 600, a conveyor belt 500, and a first reduction motor 400. The base 100 is rotatably connected to both ends of the rotating shaft 700. Two conveyor belts 500 are arranged at intervals. The inner walls of both ends of the conveyor belt 500 are respectively engaged with the rotating wheel 600. The rotating wheel 600 is fixed on different rotating shafts 700. The first reduction motor 400 is fixedly connected to the base 100 and is driven by any rotating shaft 700.

[0028] The conveyor belt 500 can be a synchronous belt or chain that matches the pulley 600.

[0029] In use, the corrugated sheet 200 is placed on the positioning component, and the first reduction motor 400 drives the rotating shaft 700 connected to it to rotate. The rotating shaft 700 drives the rotating wheel 600 to rotate, and the rotating wheel 600 drives the conveyor belt 500 to rotate, so that the conveyor belt 500 transports the corrugated sheet 200.

[0030] In addition, there may be multiple support rollers 2400 between the two rotating shafts 700. The two ends of the support rollers 2400 are set on the base 100. The support rollers 2400 are tangent to the bottom surface of the corrugated sheet 200, and play a supporting role for the corrugated sheet 200.

[0031] In one specific embodiment, reference is made to Figures 3 to 6 As shown in Figure 10, the positioning components are arranged one-to-one with the conveyor belt 500. The positioning components include a fixing plate 510, a pad 800 and an insert plate 900. Multiple fixing plates 510 are evenly fixed on the conveyor belt 500. A pad 800 is fixed on the fixing plate 510. An insert plate 900 is fixed on the pad 800. The insert plate 900 is inserted into the bottom of the inner cavity of the corrugated lobe and fits against the two side walls of the inner cavity. The corrugated plate 200 is supported on the pad 800.

[0032] The insertion plate 900 improves the synchronization between the corrugated plate 200 and the conveyor belt 500, thereby effectively ensuring that the corrugated segments to be welded are aligned with the welding components and the clamping components. The spacer block 800 keeps the corrugated plate 200 a certain height away from the conveyor belt 500, preventing interference with the operation of the welding components.

[0033] In one specific embodiment, reference is made to Figures 3 to 6 As shown, the clamping assembly includes a support shaft 1000, a connecting arm 1100, and a moving rod 1200. The support shaft 1000 is rotatably connected to the base 100. Several connecting arms 1100 are fixed at both ends of the support shaft 1000. The moving rod 1200 is fixed at the top of the connecting arms 1100 located at the same end of the support shaft 1000. The bracket 300 is fixedly connected to the connecting arm 1100 and / or the moving rod 1200.

[0034] The clamping assembly, with the support shaft 1000 as the rotation center, forms a swing clamping structure through the connecting arm 1100 and the moving rod 1200. It can drive the bracket 300, welding assembly, and clamping assembly to swing synchronously, thereby completing the positioning and clamping of the corrugated plate 200 and ensuring that the workpiece does not shake during welding.

[0035] In one specific embodiment, reference is made to Figures 3 to 6As shown, the transmission assembly includes a second geared motor 1700 and a transmission shaft 1800. The second geared motor 1700 is fixedly connected to the base 100 and is connected to any support shaft 1000. A first bevel gear 1900 is fixed on the support shaft 1000. The transmission shaft 1800 is rotatably connected to the base 100. A second bevel gear 2000 corresponding to the first bevel gear 1900 is fixed at both ends of the transmission shaft 1800, and the second bevel gear 2000 meshes with the first bevel gear 1900.

[0036] The second geared motor 1700 drives the support shaft 1000 connected to it to rotate forward or in reverse. The support shaft 1000 drives the moving rod 1200 to swing through the connecting arm 1100. Through the first bevel gear 1900, the second bevel gear 2000 and the transmission shaft 1800, the moving rods 1200 of the two clamping components swing towards or away from each other, thereby clamping or releasing the corrugated plate 200.

[0037] In one specific embodiment, reference is made to Figures 3 to 8 As shown, the lifting assembly includes a first telescopic rod 1300, a lifting plate 1400, and a clamp 1500; the welding assembly includes a welding torch 1600; the first telescopic rod 1300 is fixedly connected to the bracket 300, and the telescopic end of the first telescopic rod 1300 is fixedly connected to the lifting plate 1400; the first telescopic rod 1300 is a hydraulic cylinder or an electric cylinder; the lifting plate 1400 is bolted to the clamp 1500, and the welding torch 1600 is clamped between the two; a first guide rod 1410 is fixed on the lifting plate 1400, and the first guide rod 1410 slides through the bracket 300.

[0038] The first telescopic rod 1300 drives the lifting plate 1400 to rise or fall, and the lifting plate 1400 and the clamp 1500 drive the welding gun 1600 to rise or fall, so that the welding gun 1600 can weld the weld seam.

[0039] In one specific embodiment, reference is made to Figures 3 to 9 As shown, the clamping assembly includes a second telescopic rod 2100, a clamping bar 2200, and a connecting plate 2300. Two clamping bars 2200 are symmetrically arranged at intervals. The second telescopic rod 2100 and the clamping bar 2200 are arranged in a one-to-one correspondence. The second telescopic rod 2100 is fixedly connected to the bracket 300. The connecting plate 2300 is fixed between the telescopic end of the second telescopic rod 2100 and the clamping bar 2200. The first telescopic rod 1300 is a hydraulic cylinder or an electric cylinder. There is a safety distance of 5 to 10 mm between the side of the clamping bar 2200 near the welding assembly and the end face of the wavelet to avoid the clamping bar 2200 affecting the operation of the welding torch 1600. A second guide rod 2310 is fixed on the connecting plate 2300 and slides through the bracket 300.

[0040] Multiple stiffeners are welded between the clamping strip 2200 and the connecting plate 2300 to improve the structural strength of the clamping strip 2200 and the connecting plate 2300.

[0041] The telescopic movement of the second telescopic rod 2100 causes the connecting plate 2300 to move away from or closer to the side of the lobe, thereby causing the clamping bar 2200 to clamp or release the end of the lobe.

[0042] The clamping assembly is used to locally clamp the end of the beam, further fixing the welding area and preventing deformation; the clamping bar 2200 and the end face of the beam are kept at a safe distance to avoid interference between the clamping bar 2200 and the welding gun 1600.

[0043] In one specific embodiment, reference is made to Figure 9 As shown, the cooling component includes a liquid inlet channel 2210 and a liquid return channel 2220 formed on the clamping strip 2200. One end of the liquid inlet channel 2210 is connected to one end of the liquid return channel 2220, and the other ends of the liquid inlet channel 2210 and the liquid return channel 2220 respectively pass through the clamping strip 2200. The end of the liquid inlet channel 2210 passing through the clamping strip 2200 is connected to the liquid supply end of the refrigeration unit through a first flexible pipe and other components. The end of the liquid return channel 2220 passing through the clamping strip 2200 is connected to the liquid return end of the refrigeration unit through a second flexible pipe and other components. Coolant is supplied to the liquid inlet channel 2210 by the refrigeration unit, and the coolant then flows back to the refrigeration unit through the liquid return channel 2220. During this process, the coolant absorbs the heat generated during the welding process through the clamping strip 2200, effectively solving the problem of thermal deformation of the sheet metal caused by high-temperature heat accumulation during manual welding.

[0044] Working principle of a double-sided welded seam system for heat sinks: Workpiece loading and preliminary positioning: The corrugated sheet 200 to be processed is placed on the positioning assembly, with the bottom end of the inner cavity of the corrugated plate inserted into the insert plate 900. The corrugated sheet 200 rests on the pad 800, which improves the synchronization between the movement of the corrugated sheet 200 and the conveyor belt 500, thereby effectively ensuring that the corrugated plate to be welded can be aligned with the welding assembly and the clamping assembly. By setting the pad 800, the corrugated sheet 200 is kept at a certain height away from the conveyor belt 500, avoiding interference with the operation of the welding assembly.

[0045] Workpiece conveying and positioning: Start the first reduction motor 400, which drives the rotating shaft 700 and the rotating wheel 600 to rotate, thereby driving the two conveyor belts 500 to run synchronously, conveying the corrugated plate 200. Stop conveying when the corrugated plate to be welded is aligned with the welding torch 1600.

[0046] Overall clamping and fixing: Start the second reduction motor 1700, and the power is output through the support shaft 1000. The power is transmitted through the meshing of the first bevel gear 1900 and the second bevel gear 2000 and the transmission shaft 1800, driving the two clamping components to swing synchronously in opposite directions. The moving rod 1200 clamps the corrugated plate 200, thereby fixing the workpiece as a whole and preventing overall displacement during welding.

[0047] End clamping and locking: Activating the second telescopic rod 2100 pushes the connecting plate 2300 and clamping strip 2200 towards the end of the corrugated segment. The two clamping strips 2200 clamp the end of the corrugated segment, further reinforcing the welding area. A safe distance of 5 to 10 millimeters is maintained between the side of the clamping strip 2200 closest to the welding assembly and the end face of the corrugated segment, ensuring it does not obstruct the weld or interfere with the welding operation. Simultaneously, the externally installed refrigeration unit starts, and coolant enters the inlet and return channels inside the clamping strip 2200, forming a circulating cooling circuit.

[0048] Dynamic welding and cooling: Activating the first telescopic rod 1300 drives the lifting plate 1400, clamp 1500, and welding torch 1600 to move up and down. The welding torch 1600 welds along the side of the wave-shaped plate from top to bottom or bottom to top. The high temperature generated during welding is transferred to the clamping bar 2200. The coolant absorbs the heat and flows back to the refrigeration unit, achieving cooling and effectively preventing thermal deformation of the weld and surrounding plates due to high temperatures.

[0049] Mechanism Reset and Cyclic Operation: After the welding of a single corrugated plate is completed, the first telescopic rod 1300 drives the welding torch 1600 to reset, and the second telescopic rod 2100 drives the clamping bar 2200 to release the end of the corrugated plate. Subsequently, the transmission assembly drives the clamping assemblies on both sides to swing in opposite directions, releasing the overall clamping of the corrugated plate 200. The conveying assembly is restarted to transport the next corrugated plate to be welded to the welding station. The above clamping, welding, and cooling process is repeated to complete the processing of all corrugated plate welds in sequence. After all processes are completed, the finished workpiece is removed.

[0050] A method for welding double-sided weld seams of a heat sink: Welding corrugated sheet 200 using the welding system of any of the above embodiments.

[0051] In one specific embodiment, the specific steps are as follows: S1: The corrugated plate 200 is placed on the positioning component, that is, the insert plate 900 is inserted into the bottom of the inner cavity of the corrugated plate, and the corrugated plate 200 is supported on the pad 800. S2: The conveying component conveys the corrugated sheet 200. When the corrugated sheet 200 to be welded is aligned with the welding component, the conveying stops (the stopping and positioning can be achieved by setting a visual acquisition device, or a limit switch, or the controller to preset the single conveying distance of the conveyor belt 500, etc. This is a conventional technology that can be implemented by those skilled in the art without creative effort, and will not be elaborated on here). S3: The transmission component drives the clamping component to clamp the corrugated plate 200. At this time, the two clamping bars 2200 are located on both sides of the corrugated lobe that are aligned with the welding component, and the welding component is aligned with the weld. S4: The clamping assembly clamps the end of the beam; S5: The lifting component drives the welding component to weld the weld from top to bottom or from bottom to top. During this process, the cooling component absorbs the welding heat. S6: After welding one lobe, reset the clamping assembly, lifting assembly and holding assembly; S7: Weld the other welds in sequence according to steps S2, S3, S4, S5 and S6 above.
