Description
Technical Field

[0002] Wire harness terminals are an important component in wire harness manufacturing, used to achieve electrical connections and mechanical fixation between wire harnesses and connectors or other wire harnesses. They are connected to the conductors of the wire harness through methods such as crimping, welding, and riveting, forming a reliable electrical connection and ensuring smooth current flow between the conductor and the terminal. Simultaneously, wire harness terminals apply a certain mechanical force to the conductors of the wire harness, fixing them to the terminals and preventing the wire harness from falling off or shifting during subsequent use. Wire harness terminals also have a protective function, protecting the conductors from environmental factors and improving the reliability and safety of the connection.
[0003] Existing wire harness terminal crimping equipment can only crimp one terminal at a time, resulting in low production efficiency and creating a bottleneck in production efficiency. The efficiency of the production process is largely limited by the crimping speed of a single terminal, making it difficult to achieve synchronous crimping of multiple terminals through simple structural improvements. Furthermore, the low level of automation restricts the improvement of production efficiency. Utility Model Content

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0025] Reference Figures 1-6 As shown, a dual-mold crimping device for wire harness terminals includes a base 1. A mounting block 9 is fixedly connected to the upper surface of the base 1. Two symmetrically distributed T-shaped strips 18 are fixedly connected to the rear side of the mounting block 9. A support block 10 is slidably connected to the outer surface of the T-shaped strips 18. A fixing plate 12 is fixedly connected to the front side of the upper end of the support block 10. Two cylinders 13 are installed through the inside of the fixing plate 12. The output ends of the two cylinders 13 are respectively connected to a pressing block 19 and a fixing clamp 20. The pressing block 19 is used to fix the terminal to the wire harness. The connection position is such that the fixing clip 20 is used to crimp the terminal and the wire harness. The upper front end of the fixing plate 12 is fixedly installed with a cylinder 14. The output end of the cylinder 14 passes through the fixing plate 12 and is fixedly connected to an L-shaped column 16. The front side of the support block 10 is fixedly connected with a carrying block 21. The upper surface of the carrying block 21 is fixedly installed with a worktable 15. The front side of the carrying block 21 is provided with a storage groove 24. The outer surface of the L-shaped column 16 is slidably connected to the inside of the carrying block 21. The upper surface of the worktable 15 is slidably connected with a push plate 17.
[0026] Specifically, the base 1 and mounting block 9 provide support for the crimping structure. Two T-shaped strips 18 on the rear side of the mounting block 9 restrict the position of the support block 10, preventing movement of the structure on the support block 10 during operation. Simultaneously, protrusions on the front side of the T-shaped strips 18 fix the position of the support block 10, allowing for free adjustment of its position. Furthermore, adjusting the number of support blocks 10 on the T-shaped strips 18 can achieve dual-mode or even multi-mode crimping. During crimping, the terminal connecting strip moves the terminals and wire harness onto the worktable 15. L-shaped posts 16 separate the terminals and terminal connecting strip, facilitating subsequent terminal separation. Two cylinders 13 mounted on the fixing plate 12 drive the pressing block 19 and fixing clamp 2 below the fixing plate 12. The system operates at 0, and the terminals and wire harnesses are fixed and restricted by the pressing block 19 to prevent them from moving during crimping, which would reduce the pass rate. Then, the terminals are crimped by the fixing clamp 20. The cylinder 14 on the fixing plate 12 operates synchronously, and the cylinder 14 drives the L-shaped column 16 to move. The L-shaped column 16 moves towards the worktable 15, and the shearing force formed between the worktable 15 and the L-shaped column 16 separates the terminals and terminal connecting strips, which facilitates the subsequent collection of the wire harnesses and terminal connecting strips. At the same time, the terminal connecting strips can be collected more conveniently without cutting them off. The push plate 17 driven by the cylinder can push the crimped wire harness away and push the wire harness out of the storage slot 24, which facilitates the collection of the wire harness.
[0027] Reference Figures 1-6 As shown, a partition conveyor belt 4 is fixedly installed on the upper surface of the base 1, and a housing 5 is fixedly connected to the upper surface of the base 1; a chain conveyor belt 7 is provided inside the housing 5, an adjusting plate 6 is provided on the left side of the housing 5, and support rods 8 are fixedly connected to both the front and rear sides of the adjusting plate 6; the bottom ends of the support rods 8 are fixedly connected to the upper surface of the base 1, an extension plate 11 is provided at the right end of the partition conveyor belt 4, and the rear left end of the extension plate 11 is fixedly connected to the front side of the housing 5; a guide plate 22 is fixedly connected to the upper right side of the housing 5, and the right end of the guide plate 22 is in contact with the left side of the L-shaped column 16. The guide plate 22 is used to guide the terminal connecting belt into the shearing area between the L-shaped column 16 and the worktable 15; a connecting plate 23 is fixedly connected to the right end of the housing 5, and the right end of the connecting plate 23 is located on the left side of the load block 21.
[0028] Specifically, the outer casing 5 protects the chain conveyor belt 7 inside the casing 5, and the toothed parts on the chain conveyor belt 7 transport the terminal connecting belt, thus facilitating terminal transport and allowing adjustment of the terminal transport speed. The partition conveyor belt 4 on the front side of the casing 5 runs synchronously to transport the wire harness. The inclination of the partition conveyor belt 4 facilitates the placement of the end of the wire harness inside the crimping head of the terminal, thus facilitating subsequent crimping of the terminal. The adjusting plate 6 and support rod 8 installed on the casing 5 facilitate adjustment of the direction and height of the terminal connecting belt transport, preventing the terminal connecting belt from falling off the chain conveyor belt 7. Subsequently, the guide plate 22 adjusts the position of the terminal connecting belt after transport, so that the terminal and wire harness are placed above the workbench 15 and the terminal connecting belt is placed below the L-shaped column 16, thus facilitating the subsequent removal of the terminal connecting belt. At the same time, the extension plate 11 on the front side of the carrying block 21 transports the wire harness, thus facilitating the crimping of the terminal and wire harness.
[0029] Reference Figure 1 As shown, a vertical rod 2 is fixedly connected to the upper surface of the base 1, and a rotating shaft 3 is installed at the top of the vertical rod 2;
[0030] Specifically, the base 1 supports the upright 2 and the pivot 3 to prevent the upright 2 from falling. The pivot 3 stores the terminal connecting strip and the terminal, making it convenient for subsequent use of the terminal. At the same time, the terminal connecting strip roll on the pivot 3 can be freely removed to adapt to different specifications of terminal connecting strip rolls.
[0031] Working principle: When in use, align the groove on the support block 10 with the T-shaped strip 18 and push it in. The number of support blocks 10 can be adjusted freely according to the requirements, so as to achieve dual-mode or multi-mode crimping. At the same time, the protrusion on the front side of the T-shaped strip 18 fixes the position of the support block 10 to prevent the support block 10 from shifting during operation, which would result in poor crimping effect.
[0032] The terminal strip to be used is installed on the rotating shaft 3, and one end of the terminal strip is fed into the upper part of the housing 5 through the gap between the adjusting plate 6 and the housing 5. The protrusion extending outward on the chain conveyor belt 7 is used to lock the terminal strip in the gap, which facilitates the conveying of the terminal strip. At the same time, the chain conveyor belt 7 and the partition conveyor belt 4 are driven by external power to operate. Then, the wire harness to be crimped is conveyed by the partition conveyor belt 4. The inclined partition conveyor belt 4 facilitates the placement of the end of the wire harness at the crimping joint of the terminal during the conveying process, which facilitates the subsequent crimping of the wire harness and the terminal. Then, the operation of the chain conveyor belt 7 and the partition conveyor belt 4 sends the crimped workpiece to the support block 10.
[0033] Meanwhile, the guide plate 22 restricts the travel direction of the terminal connecting strip and the terminal, allowing the terminal connecting strip to enter below the L-shaped column 16 and the wire harness inside the terminal and crimp connector to enter above the worktable 15, thus facilitating the subsequent removal of the terminal from the terminal connecting strip. At the same time, the connecting plate 23 connected to the right side of the housing 5 provides support for the movement of the terminal, preventing the terminal from getting stuck on the left side of the support block 10 during movement, causing damage and affecting production efficiency. The extension plate 11 provides support for the wire harness, preventing the wire harness from falling off during crimping of the wire harness and the terminal, and ensuring the pass rate of wire harness terminal crimping.
[0034] During crimping, two cylinders 13 above the fixed plate 12 drive the pressing block 19 and the fixing clamp 20 below. The pressing block 19 fixes the position of the terminal and wire harness connection to prevent the wire harness from falling out of the terminal during crimping. Then, the fixing clamp 20 crimps the terminal and wire harness. At the same time, two holes on the worktable 15 facilitate the storage of the protruding part of the fixing clamp 20 during crimping, thus achieving the effect of facilitating crimping while protecting the fixing clamp 20. At the same time as crimping, the cylinder 14 on the front side of the support block 10 is activated simultaneously. The cylinder 14 pushes the L-shaped column 16 below to cut off the terminal connecting strip. The L-shaped column 16 moves towards the worktable 15. The shearing force formed between the worktable 15 and the L-shaped column 16 removes the terminal connecting strip without damaging it, which facilitates the subsequent collection of the terminal connecting strip. At the same time, the storage slot 24 on the carrying block 21 can accommodate the wire harness during crimping to prevent damage to the wire harness.
