[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The radiator base is conveyed by a conveyor belt. During welding, the radiator base is first captured and clamped by a positioning and clamping mechanism, so that the radiator base is directly facing the core conveying mechanism and the welding mechanism. The core conveying mechanism works in conjunction with the welding mechanism to continuously perform welding operations between the core body and the radiator base. Evenly spaced mating grooves are provided on the radiator base. The mating grooves cooperate with the edges of the core body to improve the reliability of welding at the joint. Before welding, the welding head is positioned at the joint end by using the longitudinal guide rail and the lifting cylinder. Then, the electric telescopic rod is controlled to move and adjust the welding angle to ensure welding quality. The welding head moves along the longitudinal guide rail to complete the welding operation between the core body and the radiator base.

[0017] (2) When clamping and positioning the radiator base on the conveyor belt, firstly, the telescopic motor 1 drives the fixed plate 2 to move, so that the clamping column at the bottom is close to the edge of the radiator base. Then, the lifting motor drives the clamping column to fall on the surface of the conveyor belt. The clamping column is used to clamp and position the two ends of the radiator base. The telescopic motor 1 on both sides of the conveyor belt and the clamping column are controlled in sequence to adjust the radiator base to the bottom of the core conveying mechanism, so as to facilitate the subsequent conveying and welding of the core body.

[0018] (3) Install the sleeve spring by bending the rod. Under the action of the sleeve spring, push the push plate to move along the snap-fit ​​groove, thereby moving all the core bodies on the tray towards the baffle. Under the action of the push motor and the push block, the core body close to the baffle falls into the limit slot and the bottom of the core body cooperates with the mating groove of the radiator base.

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0031] like Figure 1 As shown, an aluminum radiator core brazing equipment includes two sets of frames 1 and two sets of frames 2 11. The frames 2 11 are located outside the frames 1. A conveyor belt 10 is arranged between the frames 1. A movable frame 2 is arranged on the frames 2 11. A horizontal frame 21 is arranged between the movable frames 1 2. The horizontal frame 21 is movably installed along the frames 2 11. Radiator bases 6 are evenly placed on the conveyor belt 10. Positioning and clamping mechanisms 3 are symmetrically arranged between the frames 2 11. The positioning and clamping mechanisms 3 clamp the radiator bases 6 in a centered manner. A core conveying mechanism 4 is suspended and installed on the horizontal frame 21. The central axis of the core conveying mechanism 4 is located on the same vertical plane as the horizontal symmetry line of the radiator base 6. A welding mechanism 5 is arranged at the bottom of the core conveying mechanism 4.

[0032] Specifically, the radiator base 6 is conveyed by the conveyor belt 10. During the welding operation, the radiator base 6 is first captured and clamped by the positioning clamping mechanism 3, so that the radiator base 6 is facing the core conveying mechanism 4 and the welding mechanism 5. The core conveying mechanism 4, together with the welding mechanism 5, continuously performs welding operations between the core body 61 and the radiator base 6.

[0033] like Figure 2 , Figure 6 , Figure 7As shown, the radiator base 6 is provided with evenly spaced mating grooves 60, and the core body 61 is installed in the mating grooves 60. The welding mechanism 5 includes a longitudinal guide rail 50 arranged parallel to the mating grooves 60. A second lifting cylinder 51 is electrically driven and movably installed in the longitudinal guide rail 50. The second lifting cylinder 51 is connected to an installation rod 52. A universal joint 58 is provided at the center of the lower side of the installation rod 52. The first universal joint 58 is connected to a welding head 57. A second universal joint 514 is provided at the end of the installation rod 52. The second universal joint 514 is connected to an electric telescopic rod 515. The end of the electric telescopic rod 515 is hinged to the welding head 57. The hinge point between the electric telescopic rod 515 and the welding head 57 is slidably engaged with the surface of the welding head 57.

[0034] Specifically, evenly spaced mating grooves 60 are provided on the radiator base 6. These grooves 60 engage with the edges of the core body 61, improving the reliability of welding at the joint. Before welding, the welding head 57 is positioned relative to the joint end using the longitudinal guide rail 50 and the second lifting cylinder 51. Then, the electric telescopic rod 515 is moved to adjust the welding angle, ensuring welding quality. The welding head 57 moves along the longitudinal guide rail 50, completing the welding operation between the core body 61 and the radiator base 6.

[0035] Furthermore, such as Figure 7 As shown, an installation frame 53 is provided at the end of the mounting rod 52 away from the universal joint 514. A winding drum 55 is rotatably installed inside the installation frame 53. The winding drum 55 is connected to a release motor 54. Welding wire 56 is wound on the winding drum 55. The welding head 57 is hollow. A connecting pipe 59 is provided at the end of the welding head 57 facing the universal joint. The welding wire 56 passes through the connecting pipe 59 to reach the end of the welding head 57. A tensioning plate 510 is provided on the connecting pipe 59. A connecting plate 511 is provided on the edge of the tensioning plate 510. The tensioning plate 510 and the connecting plate 511 are installed perpendicularly. A conveying motor 513 is provided on the connecting plate 511. The conveying motor 513 is connected to a conveying roller 512. The welding wire 56 passes through the gap between the tensioning plate 510 and the conveying roller 512 and enters the connecting pipe 59.

[0036] Specifically, the release motor 54 drives the winding drum 55 to release the welding wire 56, while the conveying motor 513 drives the conveying roller 512 to rotate, so that the welding wire 56 is continuously conveyed between the top plate 510 and the conveying roller 512 and fed into the butt joint pipe 59, and then welded at the butt joint with the welding head 57. When the welding operation is completed, the conveying motor 513 and the release motor 54 stop operating at the same time.

[0037] Furthermore, such as Figure 3As shown, the positioning and clamping mechanism 3 includes a movable frame 30 slidably mounted on the upper surface of the frame 11. A horizontal mounting plate 31 is provided at the upper end of the movable frame 30. A matching slider 32 is provided on the side of the horizontal mounting plate 31 facing the movable frame 2. The matching slider 32 is slidably mounted with the vertical adjustment groove 20. A connecting crank rod 33 is provided at both ends of the horizontal mounting plate 31. A fixing plate 34 and a fixing plate 35 are provided at the ends of the connecting crank rod 33. The fixing plate 35 is inserted into the fixing plate 34 through a matching slider 36. A telescopic motor 37 is provided between the fixing plate 34 and the fixing plate 35. A connecting crank rod 38 is symmetrically provided at the ends of the fixing plate 35. A suspension plate 39 is provided on the connecting crank rod 38. Lifting motors 313 are provided on both sides of the bottom of the suspension plate 39. A clamping column 315 is rotatably connected to the end of the lifting motor 313.

[0038] Specifically, when clamping and positioning the radiator base 6 on the conveyor belt 10, the first telescopic motor 37 drives the second fixing plate 35 to move, so that the bottom clamping column 315 is close to the edge of the radiator base 6. Then, the lifting motor 313 drives the clamping column 315 to fall on the surface of the conveyor belt 10. The clamping column 315 is used to clamp and position the two ends of the radiator base 6. The telescopic motors 37 on both sides of the conveyor belt 10 and the clamping column 315 are controlled in sequence to adjust the radiator base 6 to be directly below the core conveying mechanism 4, so as to facilitate the subsequent conveying and welding of the core body 61.

[0039] Furthermore, such as Figure 3 As shown, the clamping column 315 is provided with a first mating groove 316, and the side of the suspension plate 39 is symmetrically provided with an arc-shaped frame 310. A mating rod 314 is slidably installed in the arc-shaped frame 310. A translation frame 311 is provided at the upper end of the mating rod 314 on both sides. A second mating groove 317 is provided at both ends of the translation frame 311. The upper end of the mating rod 314 is slidably installed with the second mating groove 317, and the lower end of the mating rod 314 is slidably installed with the first mating groove 316. A second telescopic motor 312 is provided between the translation frame 311 and the suspension plate 39.

[0040] Specifically, by setting up an arc-shaped frame 310 to slide and install the mating rod 314, combined with the telescopic motor 312, the translation frame 311, and the mating groove 317, the mating rod 314 is driven to slide along the arc-shaped frame 310. At the same time, a mating groove 316 is set on the clamping column 315. The movement of the mating rod 314 drives the clamping column 315 to rotate around the rotational installation center, thereby achieving the clamping and positioning of the radiator base 6.

[0041] Furthermore, such as Figure 4 , Figure 5As shown, the core conveying mechanism 4 includes a lifting cylinder 40 connected to the moving block 23. The end of the lifting cylinder 40 is connected to a suspension frame 41. The bottom of the suspension frame 41 is provided with a connecting column 43. The connecting column 43 is connected to a support plate 42. The bottom of the suspension frame 41 is provided with a baffle 48. The support plate 42 is symmetrically provided with snap-fit ​​grooves 44. A push plate 45 is slidably installed in the snap-fit ​​grooves 44. The core body 61 is evenly placed between the push plate 45 and the baffle 48. The end of the support plate 42 near the baffle 48 is provided with a drop groove 411. A feeding component is provided at the drop groove 411. The feeding assembly includes a curved rod 46 mounted on a suspension frame 41, with the end of the curved rod 46 facing the push plate 45. A sleeve spring 47 is mounted on the curved rod 46 and abuts against the side of the push plate 45. A feeding motor 49 is mounted on the suspension frame 41 near the baffle 48. The feeding motor 49 is connected to a push block 410, which pushes the core body 61 down along the drop groove 411. A limiting slot 412 is provided at the bottom of the support plate 42 at the position of the drop groove 411, and the limiting slot 412 cooperates with the core body 61.

[0042] Specifically, a spring 47 is installed by bending rod 46. Under the action of spring 47, push plate 45 moves along locking groove 44, thereby moving all core bodies 61 on support plate 42 toward baffle 48. One core body 61 close to baffle 48 falls into limiting slot 412 under the action of pusher motor 49 and push block 410, and the bottom of core body 61 cooperates with the mating groove 60 of radiator base 6.

[0043] It is important to note that after each welding operation of the core body 61, the moving distance of the mating moving block 23 is equal to the distance between adjacent mating grooves 60. This ensures that the core body 61 accurately mates with the mating grooves 60 when it falls, thereby guaranteeing the welding reliability of the core body 61 during subsequent welding. After falling, the upper part of the core body 61 still mates with the limiting slot 412, which maintains the vertical position of the core body 61. This ensures that the core body 61 and the heat sink base 6 are welded perpendicularly during the welding operation, guaranteeing welding quality.

[0044] Furthermore, the upper port of the drop groove 411 is chamfered, and the baffle 48 is uniformly provided with rubber protrusions on the side facing the core body 61.

[0045] A method for using the above-mentioned aluminum radiator core brazing equipment includes the following steps: S1, positioning and clamping: the clamping column 315 is controlled by the telescopic motor 37 to approach the edge of the radiator base 6 on the conveyor belt 10, and the translation frame 311 is moved forward by the telescopic motor 312, which drives the two mating rods 314 to move closer to each other, so that the clamping column 315 clamps the radiator base 6 in a centered manner; S2, core conveying: the core body 61 is controlled by the unloading component to push it downward, so that the core body 61 falls into the limiting slot 412. The bottom of the core body 61 is mated with the mating groove 60, and the upper end of the core body 61 is still mated with the limiting slot 412, keeping the core body 61 in a vertical state; S3, welding: the welding head 57 is driven by the lifting cylinder 51 to approach the joint of the core body 61 and the mating groove 60, and welding is performed in conjunction with the longitudinal guide rail 50 and the continuously conveyed welding wire 56.

[0046] The working principle of this invention embodiment is as follows:

[0047] like Figures 1-7As shown, the radiator base 6 is conveyed by the conveyor belt 10. During welding, the radiator base 6 is first captured and clamped by the positioning clamping mechanism 3, so that the radiator base 6 is directly facing the core conveying mechanism 4 and the welding mechanism 5. The core conveying mechanism 4, in conjunction with the welding mechanism 5, continuously performs welding operations between the core body 61 and the radiator base 6. Evenly spaced mating grooves 60 are provided on the radiator base 6. The mating grooves 60 and the edges of the core body 61 engage with each other, improving the reliability of welding at the joint. Before welding, the welding head 57 is positioned at the joint end using the longitudinal guide rail 50 and the lifting cylinder 51. Then, the electric telescopic rod 515 is moved to adjust the welding angle, thereby ensuring welding quality. The welding head 57 moves along the longitudinal guide rail 50 to complete the welding operation between the core body 61 and the radiator base 6. The release motor 54 drives the winding drum 55 to release the welding wire 56, and at the same time, the conveyor motor 513 drives the conveyor roller 512 to rotate, so that the welding wire 56 is continuously conveyed between the top plate 510 and the conveyor roller 512 and fed into the butt joint pipe 59, and then welded at the butt joint with the welding head 57. When the welding operation is finished, the conveyor motor 513 and the release motor 54 stop operating at the same time. When clamping and positioning the radiator base 6 on the conveyor belt 10, the telescopic motor 37 first drives the fixed plate 35 to move, so that the bottom clamping column 315 is close to the edge of the radiator base 6. Then, the lifting motor 313 drives the clamping column 315 to fall on the surface of the conveyor belt 10, and the clamping column 315 is used to clamp and position the two ends of the radiator base 6. The telescopic motors 37 on both sides of the conveyor belt 10 and the clamping column 315 are controlled in sequence to adjust the radiator base 6 to be directly below the core conveying mechanism 4, so as to facilitate the subsequent conveying and welding of the core body 61. By setting an arc-shaped frame 310 to slide and install the mating rod 314, combined with the telescopic motor 312, the translation frame 311, and the mating groove 317, the mating rod 314 is driven to slide along the arc-shaped frame 310. At the same time, a mating groove 316 is set on the clamping column 315. The movement of the mating rod 314 drives the clamping column 315 to rotate around the rotational installation center, thereby achieving the clamping and positioning of the radiator base 6. By installing a sleeve spring 47 on the bending rod 46, under the action of the sleeve spring 47, the push plate 45 is pushed to move along the snap-fit ​​groove 44, thereby moving all the core bodies 61 on the support plate 42 toward the baffle 48. One core body 61 near the baffle 48 falls into the limiting snap-fit ​​groove 412 under the action of the pusher motor 49 and the push block 410, and the bottom of the core body 61 and the mating groove 60 of the radiator base 6 cooperate with each other. It should be noted that after each welding operation of the core body 61 is completed, the moving distance of the mating moving block 23 is equal to the distance between the adjacent mating grooves 60, thereby ensuring that the core body 61 accurately mates with the mating grooves 60 when it falls, and thus ensuring the welding reliability of the core body 61 during subsequent welding.After the core body 61 is lowered, its upper part still cooperates with the limiting slot 412. The limiting slot 412 keeps the core body 61 in a vertical state, so that the core body 61 and the heat sink base 6 are welded in a vertical state during the welding operation, thus ensuring the welding quality.
