[0034] Specifically, mating grooves 60 are evenly arranged on the radiator base 6, and the edges of the mating grooves 60 and the core body 61 are used in cooperation to improve the reliability during welding at the joint part. Before welding, first, the welding head 57 is positioned at the end of the joint in combination with the longitudinal guide rail 50 and the elevating cylinder II 51, and then the electric telescopic rod 515 is controlled to move to adjust the welding angle, so as to ensure the welding quality. The welding head 57 translates along the longitudinal guide rail 50 to complete the welding operation between the core body 61 and the radiator base 6.

[0035] Further, as Figure 7 shown, an installation frame 53 is arranged at one end of the installation rod 52 away from the universal joint II 514.

[0036] Specifically, the release motor 54 drives the wire winding drum 55 to release the welding wire 56, and at the same time, the conveying motor 513 drives the conveying roller 512 to rotate, so that the welding wire 56 is continuously conveyed between the pressing plate 510 and the conveying roller 512 and sent into the butt joint pipe 59, and the welding head 57 performs welding operation on the joint part. When the welding operation is over, the conveying motor 513 and the release motor 54 stop running at the same time.

[0037] Further, as Figure 3As shown in the figure, the positioning and clamping mechanism 3 includes a second moving frame 30 slidably mounted on the upper surface of the second frame 11. A horizontal mounting plate 31 is provided at the upper end of the second moving frame 30. A mating slider 32 is provided on the side of the horizontal mounting plate 31 facing the first moving frame 2. The mating slider 32 is slidably mounted between the vertical adjustment grooves 20.

[0038] Specifically, when clamping and positioning the radiator base 6 on the conveyor belt 10, first, the telescopic motor 37 drives the fixing plate 35 to move, so that the bottom clamping column 315 approaches the edge of the radiator base 6. Subsequently, 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 both ends of the radiator base 6. The telescopic motors 37 and the clamping columns 315 on both sides of the conveyor belt 10 are controlled in sequence to adjust the radiator base 6 directly below the core conveying mechanism 4, so as to facilitate the subsequent conveying and welding operations of the core body 61.

[0039] Further, as Figure 3 shown, a mating groove 316 is provided on the clamping column 315. Arc-shaped frames 310 are symmetrically provided on the side of the hanging plate 39.

The lower ends of the mating rods 314 are slidably mounted between the mating grooves 316. A telescopic motor 312 is provided between the translating frame 311 and the hanging plate 39.

[0040] Specifically, by arranging the arc-shaped frame 310 to slidably mount the mating rod 314, combined with the telescopic motor 312, the translating frame 311 and the mating groove 317 drive the mating rod 314 to slide along the arc-shaped frame 310. At the same time, a mating groove 316 is provided on the clamping column 315. The movement of the mating rod 314 is used to drive the clamping column 315 to rotate around the rotation installation center, so as to realize the clamping and positioning of the radiator base 6.

[0041] Further, as Figure 4 、 Figure 5As shown, the core conveying mechanism 4 includes a lifting cylinder 40 connected to the mating moving block 23. The end of the lifting cylinder 40 is connected with a suspension bracket 41. A connecting column 43 is arranged at the bottom of the suspension bracket 41. The connecting column 43 is connected with a support plate 42. A baffle 48 is arranged at the bottom of the suspension bracket 41. Clamping chutes 44 are symmetrically arranged on the support plate 42. A push plate 45 is slidably installed in the clamping chutes 44. Core bodies 61 are evenly placed between the push plate 45 and the baffle 48. A falling groove 411 is arranged at one end of the support plate 42 close to the baffle 48. A blanking assembly is arranged at the position of the falling groove 411. The blanking assembly includes a bending rod 46 arranged on a suspension plate 39. The end of the bending rod 46 faces the push plate 45. A socket spring 47 is arranged on the bending rod 46. The socket spring 47 abuts against the side of the push plate 45. A pushing motor 49 is arranged on the suspension plate 39 close to the baffle 48. The pushing motor 49 is connected with a push block 410. The push block 410 pushes the core body 61 to fall along the falling groove 411. A limit card slot 412 is arranged at the position of the falling groove 411 at the bottom of the support plate 42. The limit card slot 412 and the core body 61 cooperate with each other.

[0042] Specifically, the socket spring 47 is installed through the bending rod 46. Under the action of the socket spring 47, the push plate 45 is pushed to move along the clamping chute 44, so as to move all the core bodies 61 on the support plate 42 towards the baffle 48. One core body 61 close to the baffle 48 falls into the limit card slot 412 under the action of the pushing motor 49 and the push block 410, and the bottom of the core body 61 cooperates with the mating groove 60 of the radiator base 6.

[0043] 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 adjacent mating grooves 60, so as to ensure that the core body 61 accurately cooperates with the mating groove 60 when falling, and further ensure the welding reliability of the core body 61 during subsequent welding. After the core body 61 falls, the upper part of the core body 61 still cooperates with the limit card slot 412, and the limit card slot 412 is used to keep the core body 61 in a vertical state, so that the core body 61 and the radiator base 6 are welded vertically during the welding operation, ensuring the welding quality.

[0044] Furthermore, a chamfer is arranged at the upper port of the falling groove 411. Rubber protrusions are evenly arranged on the side of the baffle 48 facing the core body 61.

Positioning and clamping: The telescopic motor 1 controls the clamping column 315 to approach the edge of the radiator base 6 on the conveyor belt 10, and then the telescopic motor 2 controls the translation frame 311 to move forward, driving the two cooperating rods 314 to approach each other, so that the clamping column 315 performs centering clamping on the radiator base 6; S2. Core conveying: The blanking assembly controls the core body 61 to be pushed downward, so that the core body 61 falls into the limit card slot 412. The bottom of the core body 61 cooperates with the mating groove 60, and the upper end of the core body 61 still cooperates with the limit card slot 412 to keep the core body 61 in a vertical state; S3. Welding: The lifting cylinder 2 drives the welding head 57 to approach the joint part of the core body 61 and the mating groove 60, and welding operations are carried out in combination with the longitudinal guide rail 50 and the continuously fed welding wire 56.

[0046] The working principle of the embodiment of the present invention is:

[0047] Such as Figures 1-7As shown, the radiator base 6 is conveyed by the conveyor belt 10. During the welding operation, first, the positioning and clamping mechanism 3 captures and centers and clamps the radiator base 6, so that the radiator base 6 faces the core conveying mechanism 4 and the welding mechanism 5. Among them, the core conveying mechanism 4 cooperates with the welding mechanism 5 to continuously perform sequential welding operations between the core body 61 and the radiator base 6. Matching grooves 60 are uniformly arranged on the radiator base 6, and the edges of the matching grooves 60 and the core body 61 are used to cooperate with each other to improve the reliability during welding at the joint part. Before welding, first, the longitudinal guide rail 50 and the lifting cylinder two 51 are combined to control the welding head 57 to be positioned at the joint end, and then the electric telescopic rod 515 is controlled to move to adjust the welding angle, so as to ensure the welding quality. The welding head 57 translates 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 wire reel 55 to release the welding wire 56, and at the same time, the conveying motor 513 drives the conveying roller 512 to rotate, so that the welding wire 56 is continuously conveyed between the pressing plate 510 and the conveying roller 512 and sent into the butt joint pipe 59, and the welding head 57 performs welding operations on the joint part. When the welding operation is completed, the conveying motor 513 and the release motor 54 stop running at the same time. When clamping and positioning the radiator base 6 on the conveyor belt 10, first, the telescopic motor one 37 drives the fixing plate two 35 to move, so that the clamping column 315 at the bottom approaches the edge of the radiator base 6, and 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 end parts of the radiator base 6. The telescopic motor one 37 and the clamping column 315 on both sides of the conveyor belt 10 are sequentially controlled to adjust the radiator base 6 directly below the core conveying mechanism 4, so as to facilitate the subsequent conveying and welding operations of the core body 61. By arranging the arc-shaped frame 310 to slidably install the matching rod 314, combining the telescopic motor two 312, the translation frame 311, and the matching groove two 317 to drive the matching rod 314 to slide along the arc-shaped frame 310, and at the same time, a matching groove one 316 is arranged on the clamping column 315, and the movement of the matching rod 314 is used to drive the clamping column 315 to rotate around the rotation installation center, so as to realize the clamping and positioning of the radiator base 6. The bending rod 46 is installed with the socket spring 47. Under the action of the socket spring 47, the push plate 45 is pushed to move along the clamping chute 44, and then all the core bodies 61 on the support plate 42 are moved towards the baffle 48. One core body 61 close to the baffle 48 falls into the limit card slot 412 under the action of the pushing motor 49 and the push block 410, and the bottom of the core body 61 and the matching 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 matching moving block 23 is equal to the distance between adjacent matching grooves 60, so as to ensure that the core body 61 accurately cooperates with the matching groove 60 when falling, and further ensure the welding reliability of the core body 61 during subsequent welding.After the core body 61 falls, its upper part still cooperates with the limit card slot 412, and the limit card slot 412 is used to maintain the vertical state of the core body 61, so that the core body 61 and the radiator base 6 are welded vertically during the welding operation, ensuring the welding quality.
