Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold row welding, in particular to a water-cooled radiator cold row welding machine. BACKGROUND

[0002] In a water-cooled radiator, the heat dissipation performance of the cold row is largely dependent on the welding quality between the copper pipe and the fin. The copper pipe is responsible for transporting the cooling liquid, and the fin serves to expand the heat dissipation area. The close combination of the two is the key to ensuring efficient heat transfer.

[0003] The existing process mostly adopts a horizontal lying position of the fin combined with manual welding. This operation mode has obvious defects: on the one hand, since the fin is in a horizontal lying position, a hidden area is formed at the bottom of the copper pipe and fin welding end, and the welding torch of the welder is difficult to extend into this part for precise operation, which easily causes insufficient welding at the bottom; on the other hand, the welding posture of the horizontal lying position causes the molten solder solution to only flow downward under the action of gravity, and cannot fully fill the internal gap of the copper pipe and fin welding end. Most of the molten solution accumulates outside the welding end, and only a small amount can penetrate into the bonding surface, which directly leads to the phenomenon of virtual welding at the welding end.

[0036] Please refer to the accompanying drawings Figure 5 The one end of the limiting column 502 away from the rotating table 501 is fixedly connected with the U-shaped mounting bracket 503, the inner top wall of the mounting bracket 503 is provided with a sliding groove, the sliding groove is slidably connected with the trapezoidal limiting block 519, the side wall of the limiting block 519 is fixedly connected with the elastic piece one 504, the one end of the elastic piece one 504 away from the limiting block 519 is fixedly installed on the inner side wall of the sliding groove, and the inner side wall surface of the mounting bracket 503 is rotationally connected with the counterweight plate 505 on the side of the inclined surface of the limiting block 519.

[0037] Specifically, when the limiting column 502 is kept vertical upward, the limiting block 519 is slidably accommodated in the mounting bracket 503 by the elastic force of the elastic piece one 504, so that the copper pipe 9 can pass through, when the copper pipe 9 is turned over, the limiting column 502 is rotated 180 DEG from vertical upward to vertical downward, in the rotating process, the limiting block 519 is slid downward under the influence of gravity, so as to move to the end of the copper pipe 9 to limit the copper pipe 9, and in the process of rotating the limiting column 502 from horizontal downward, the counterweight plate 505 is rotated and inclined, and the limiting block 519 is limited by the gravity of the counterweight plate 505, so as to avoid the limiting block 519 from sliding into the mounting bracket 503 when the limiting column 502 is vertical downward, through the cooperation of the limiting block 519 and the counterweight plate 505, the end of the copper pipe 9 can be automatically limited when the copper pipe 9 is turned over, so as to avoid the copper pipe 9 from falling off.

[0038] Please refer to the accompanying drawings Figure 4The rotating table 501 comprises a motor 2 5011 fixedly installed on the upper surface of the placing table 4, and a work-shaped bearing seat 5012 fixedly connected to the driving end of the motor 2 5011 and fixedly connected with the placing table 4.

[0039] Specifically, the bearing seat 5012 is used for limiting the bottom end of the copper pipe 9, and when welding, the motor 2 5011 drives the bearing seat 5012 to rotate, so that the copper pipe 9 and the fin 11 are rotated for welding.

[0040] Please refer to the accompanying drawings Figure 4 The conveying assembly 5 further comprises a supporting ring 506 sleeved on the outside of the copper pipe 9 and located below the tin ring 2 10 and the fin 11, a rotating ring 507 rotatably connected to the bottom end of the supporting ring 506, an L-shaped supporting frame 508 fixedly connected to the lower surface of the rotating ring 507, and the bottom end of the supporting frame 508 is fixedly connected with the rotating table 501.

[0041] Specifically, the supporting ring 506 is used for limiting the fin 11, so as to achieve the effect of concentric positioning of the copper pipe 9 and the fin 11, the supporting ring 506 is limited and supported by the supporting frame 508 and the rotating ring 507, and the supporting ring 506 can rotate with the fin 11 through the rotatable connection between the rotating ring 507 and the supporting ring 506.

[0042] Embodiment two, please refer to the accompanying drawings Figure 4 Since the tin ring 2 10 is located between the fin 11 and the rotating table 501, after the limiting column 502 is flipped vertically downward, the position of the tin ring 2 10 is not fixed and cannot be stably attached to the welding position of the fin 11 and the copper pipe 9. Therefore, the present embodiment proposes the following technical solution to solve the above problems, the conveying assembly 5 further comprises an arc-shaped counterweight ring 1 509 sleeved on the outside of the copper pipe 9 and located below the tin ring 2 10, an extension arm 510 fixedly connected to the outer wall of the counterweight ring 1 509, the supporting frame 508 penetrates through the extension arm 510, and the extension arm 510 is made of ferromagnetic material.

[0043] Specifically, the supporting frame 508 is used for limiting the moving direction of the counterweight ring 1 509, and when the limiting column 502 is flipped downward, the tin ring 2 10 is automatically moved to the copper pipe 9 by the counterweight ring 1 509 itself, so that the tin ring 2 10 is moved to the welding position of the fin 11 and the copper pipe 9.

[0044] Please refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 11 The upper surface of the machine body 1 is provided with an opening 15 at the center region, and the opening 15 is provided with notches 16 on both sides for the extension arm 510 to rotate through, and the inner top wall of the machine body 1 is fixedly connected with magnetic blocks 17 on both sides of the opening 15.

[0045] Specifically, opening 15 is used to allow copper tube 9 and fin 11 to pass through when the turntable 501 rotates. Notch 16 is located on the rotation trajectory of extension arm 510, so that extension arm 510 can pass through body 1. After limit post 502 flips vertically downward, extension arm 510 rotates to below magnetic block 17. Through the magnetic attraction between magnetic block 17 and extension arm 510, counterweight ring 1 509 slides upward, thereby exposing the upper space of tin ring 2 10 for welding.

[0046] In Example 3, please refer to the attached drawings. Since the copper tube 9 and the limiting post 502 are inserted and matched, when the motor 5011 rotates and drives the limiting post 502 to rotate, the limiting post 502 may not be able to drive the copper tube 9 to rotate synchronously by relying solely on the friction between the two. Therefore, this embodiment proposes the following technical solution to solve the above problem: The bearing seat 5012 is composed of an upper ring body, a cylindrical body and a lower ring body. The surface of the upper ring body is provided with a slot. An arc-shaped clamping arm 511 is slidably connected above the slot. An elastic element 512 is fixedly connected to the lower side wall of the clamping arm 511. The end of the elastic element 512 away from the clamping arm 511 is fixedly connected to the slot.

[0047] Specifically, the elastic force of the elastic element 512 drives the clamping arm 511 to slide away from the limiting post 502, so that there is a certain thickness between the clamping arm 511 and the limiting post 502, so that the copper tube 9 can be inserted.

[0048] Please see the appendix Figure 6 - Appendix Figure 7 A counterweight ring 513 is slidably connected to the outer side of the cylinder in the vertical direction. An extension layer 514 is fixedly connected to both sides of the counterweight ring 513. An extrusion block 515 is fixedly connected above the extension layer 514. A V-shaped groove is opened on the side of the extrusion block 515 facing the extrusion head 520. A U-shaped connector 521 is fixedly connected to the lower surface of the two extension layers 514. The connector 521 passes through the lower ring body. An L-shaped extrusion head 520 that passes through the slot is fixedly connected to the bottom end of the clamping arm 511. Lifting plates 20 with trapezoidal cross-sections are fixedly connected to both sides of the inner wall of the top plate 19. When the limiting post 502 is vertically upward, the lower surface of the lifting plate 20 is lower than the lower surface of the connector 521, while the upper surface of the lifting plate 20 is higher than the lower surface of the connector 521.

[0049] Specifically, when the limiting column 502 is vertically upward, the counterweight ring two 513 slides away from the copper pipe 9 by its own gravity, so that the inclined surface of the extrusion block 515 horizontally pushes the extrusion head 520 to move, so that the extrusion head 520 drives the clamping arm 511 to move to the side of the copper pipe 9, so that the clamping arm 511 clamps the copper pipe 9 through the gravity of the counterweight ring two 513, which has the effect of stabilizing the connection between the copper pipe 9 and the limiting column 502, so that the copper pipe 9 can rotate synchronously with the limiting column 502, and when the limiting column 502 is vertically downward, the counterweight ring two 513 slides towards the copper pipe 9 by its own gravity, so that the clamping arm 511 clamps the copper pipe 9 again, and when the conveying assembly 5 moves to one side of the machine body 1 to wait for the copper pipe 9 to be placed, in this process, the inclined surface of the lifting plate 20 is inserted below the connecting piece 521 and gradually lifts the connecting piece 521, so that the extrusion head 520 moves to the center of the groove, so that the extrusion block 515 does not push the extrusion head 520, so that the clamping arm 511 can be slid open for the installation of the copper pipe 9.

[0050] Embodiment four, please refer to the attached Figure 8 -attached Figure 9 Because some debris will be generated during welding, it is not convenient to clean the debris falling into the heat dissipation grooves of the fins 11, therefore, the embodiment proposes the following technical solutions to solve the above problems, the support ring 506 is provided with two upper and lower frames 516 matched with the shape of the fins 11, wherein the lower frame 516 is fixedly connected with the support ring 506, and a plurality of inserts 517 are fixedly connected to the inner side wall of the frame 516 corresponding to the heat dissipation grooves of the fins 11, and the opposite side of the upper and lower frames 516 is fixedly connected with a connecting plate 518, and the length, width and spacing of the inserts 517 are set according to the length, width and spacing of the heat dissipation grooves of the fins 11, so as to keep consistent.

[0051] Specifically, when the fins 11 pass through the copper pipe 9, the inserts 517 are inserted into the heat dissipation grooves of the fins 11, thereby plugging the two ends of the heat dissipation grooves of the fins 11, so as to avoid the debris splashing in the heat dissipation grooves of the fins 11 during welding.

[0052] Please refer to the attached Figure 10 , a blanking assembly 6 is installed below the opening 15, and the blanking assembly 6 comprises a conveying device 61, a plurality of equally spaced blanking cylinders 62 are fixedly connected to the conveying belt of the conveying device 61, and a cut is formed in the side wall of the blanking cylinder 62 to form an arc-shaped transverse section of the blanking cylinder 62, the diameter of the blanking cylinder 62 is the same as the diameter of the limiting column 502, and a rubber buffer pad is sleeved on the surface of the limiting column 502 to buffer the impact force when the welded product slides down, thereby keeping the welded product.

[0053] Specifically, after the copper pipe 9 and the fin 11 are welded, the conveying device 61 is operated to move the blanking cylinder 62 directly below the limiting column 502, the limiting block 519 can pass through the cutout of the blanking cylinder 62 to abut against the inner wall of the blanking cylinder 62, and the limiting block 519 is slid to the inside of the mounting frame 503 under the pushing of the blanking cylinder 62, so that the bottom end of the copper pipe 9 can slide down to the blanking cylinder 62 without limitation, thereby realizing automatic blanking of the welded product, and manual material taking is not needed.

[0054] In use, the tin ring two 10, the copper pipe 9 and the tin ring one 8 are sequentially inserted through the limiting shaft, then the fin 11 is inserted into the outside of the copper pipe 9, the slide table 2 is slid by the electric push cylinder two 18 to move the limiting column 502 below the welding head 14, the electric push cylinder one 13 is extended to drive the welding head 14 to descend to the tin ring one 8, then the motor two 5011 is operated to drive the bearing seat 5012 to rotate, so that the copper pipe 9 and the fin 11 are rotated by one circle for welding, the welding of one welding end of the fin 11 and the copper pipe 9 is completed, then the placing table 4 is rotated by 180° by the operation of the motor one 12 to turn over the copper pipe 9, and the welding head 14 is lowered to the tin ring two 10 by the extension of the electric push cylinder two 18 to perform welding, and the welding of the other welding end of the fin 11 and the copper pipe 9 is completed by rotating the limiting column 502 by one circle during welding.

[0055] When the copper pipe 9 is turned over, the limiting column 502 is rotated by 180° from vertical upward to vertical downward, and in the rotating process, the limiting block 519 is affected by gravity to slide downward, so as to move to the end of the copper pipe 9 to limit the copper pipe 9, and in the process of the limiting column 502 rotating from horizontal downward, the counterweight plate 505 is rotated to be inclined, so as to limit the limiting block 519, avoiding the limiting block 519 from sliding to the inside of the mounting frame 503 when the limiting column 502 is vertically downward, and through the cooperation of the limiting block 519 and the counterweight plate 505, the end of the copper pipe 9 can be automatically limited when the copper pipe 9 is turned over, avoiding the copper pipe 9 from falling off.

[0056] When the limiting column 502 is turned over downward, the tin ring two 10 is moved to the copper pipe 9 by the counterweight ring one 509, so that the tin ring two 10 moves to the welding position of the fin 11 and the copper pipe 9, after the limiting column 502 is turned over vertically downward, the extension arm 510 is rotated to be below the magnetic block 17, the counterweight ring one 509 is driven to slide upward by the magnetic attraction between the magnetic block 17 and the extension arm 510, so as to expose the upper space of the tin solder two for welding.

[0057] When the limiting column 502 is vertically upward, the counterweight ring two 513 slides away from the copper pipe 9 by its own gravity, so that the inclined surface of the extrusion block 515 pushes the extrusion head 520 horizontally to move, so that the extrusion head 520 drives the clamping arm 511 to move to the side of the copper pipe 9, so that the clamping arm 511 clamps the copper pipe 9 by the gravity of the counterweight ring two 513, which has the effect of stabilizing the connection between the copper pipe 9 and the limiting column 502, so that the copper pipe 9 can rotate synchronously with the limiting column 502, and when the limiting column 502 is vertically downward, the counterweight ring two 513 slides towards the copper pipe 9 by its own gravity, so that the clamping arm 511 clamps the copper pipe 9 again, and when the conveying assembly 5 moves to one side of the machine body 1 to wait for the placement of the copper pipe 9, in this process, the inclined surface of the lifting plate 20 is inserted below the connecting piece 521 and gradually lifts the connecting piece 521, so that the extrusion head 520 moves to the center of the groove, so that the extrusion block 515 does not push the extrusion head 520, so that the clamping arm 511 can be slid open for the installation of the copper pipe 9.

[0058] After the copper pipe 9 and the fin 11 are welded, the conveying device 61 is operated to make the blanking cylinder 62 move directly below the limiting column 502, so that the limiting block 519 can pass through the cutout of the blanking cylinder 62 and abut against the inner wall of the blanking cylinder 62, and under the pushing of the blanking cylinder 62, the limiting block 519 slides to the inside of the mounting frame 503, so that the bottom end of the copper pipe 9 can slide down from the limiting column 502 to the blanking cylinder 62, thereby realizing the automatic blanking of the welded product, so that manual material taking is not needed.
