Description

Technical Field

[0001] This utility model belongs to the technical field of cable welding equipment, specifically relating to a multi-station terminal welding mechanism. Background Technology

[0002] Currently, existing methods for welding ring-shaped terminals typically involve first cutting off a section of the cable's outer sheath to expose the cable, and then welding it to the ring-shaped terminal using high temperature. Existing automated terminal welding generally uses a conveyor belt to transport the terminal to the welding equipment. After the cable extends under the welding equipment and aligns with the terminal, the welding equipment presses down to complete the welding. This welding method generally uses a conveyor belt to drive the terminal strip, which requires high precision in conveyor belt distance and is costly. To solve this problem, this solution was developed. Utility Model Content

[0030] The wire seat 5 is located on one side below the stamping seat 2. The horizontal projection of the wire seat 5 coincides with the horizontal projection of the stamping column 9. The wire seat 5 includes a base 51, a bottom plate 53, an upper plate 52, and multiple deformable wire cylinders 55. At least two support columns 54 are formed on the bottom plate 53. The upper plate 52 has a through hole. The support columns 54 pass through the through hole and have a retaining ring 541 at their upper ends. A return spring 542 is provided on the circumference of the support column 54. Multiple first arc-shaped grooves are formed on the upper surface of the bottom plate 53, and multiple second arc-shaped grooves are formed on the lower surface of the upper plate 52. The multiple first arc-shaped grooves are respectively adapted to the multiple second arc-shaped grooves. The deformable wire cylinders 55 are fixedly installed in the first arc-shaped grooves. In this solution, the deformable wire cylinders 55 are made of metal, such as aluminum or copper. The bottom plate 53 is set on the upper surface of the base 51.

[0034] The cutting device 8 is an existing cable cutting device 8, which is used to strip and cut the cable. The cutting device 8 is located on one side of the conductor seat 5.

[0035] Working principle: As shown in the figure, the cable is fed into the deformable guide tube 55 of the guide tube seat 5. The cable extends out of the deformable guide tube and reaches below the cutting device 8. The cutting device 8 strips the cable. Then, the moving seat moves to the position corresponding to the guide block 6. The motor in the rotating table 57 drives the guide tube seat 5 to rotate 90 degrees. At this time, the cable is just above the guide block 6. The stamping drive assembly drives the stamping seat 2 to press down, so that the heating wire 21 presses the end and terminal of the cable. After heating and welding, the stamping seat 2 and the clamping seat 3 reset. During the reset process of the clamping seat 3, the flexible pressure block 341 contacts the terminal strip 10. The flexible pressure block 341 pushes the terminal strip 10 forward. The moving seat moves a specified distance so that another cable is aligned with the terminal on its terminal strip 10. The stamping seat 2 then performs the stamping... During the stamping process, the stamping column 9 moves down along with the stamping seat 2, pressing the upper plate 52 of the wire seat 5. The upper plate 52 and the base move closer together, compressing the deformable wire cylinder 55 to deform, thus fixing the cable. This process is repeated until multiple cables are welded to terminals. Then, the motor in the rotating table 57 drives the wire seat 5 to reset. Because the wire is pressed by the stamping column 9 during the welding process, the deformable wire cylinder 55 is deformed, which limits the cable. When the moving seat moves, the cable will not move backward. Then, a special wire pulling device clamps the welded cable and moves it at a fixed distance. The cutting device 8 cuts the cable at the fixed distance, and then strips the insulation from the ends of the subsequent cables. The above steps are repeated to achieve automated cable welding.
