Abstract
Description
Technical Field
[0001] This utility model relates to the field of crimping tool technology, specifically a wire harness terminal crimping mechanism. Background Technology
[0002] Wire harness terminals are metal connectors that enable electrical connections between wires and electrical components, and between wires themselves. They are widely used in wire harness systems in the automotive, electronics, home appliance, and industrial equipment industries. They are mostly made of copper or copper alloys, and some surfaces are plated with tin, nickel, or gold to improve conductivity, corrosion resistance, and oxidation resistance, ensuring long-term stable current transmission. A crimping mechanism is required during the processing and production of wire harness terminals.
[0003] In current wire harness terminal crimping operations, most crimping is done manually. Manual crimping makes it difficult to ensure the precise alignment of the terminal and wire harness relative positions each time, which can easily lead to terminal crimping position deviation, reducing the contact area and increasing the contact resistance at the crimping point. This seriously affects the stability of the electrical connection and may cause potential hazards such as overheating and open circuits during long-term use, thereby reducing product quality and reliability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 As shown, a wire harness terminal crimping mechanism includes a mounting box 1. A crimping mechanism 2 is installed in the front opening of the mounting box 1. The mounting box 1 serves as the bearing and control center of the entire crimping mechanism 2. An internal air pump is provided to provide a stable pressure source for the crimping action. The electrical control unit consists of a PLC controller, relays, and a touch panel, responsible for receiving operation commands and coordinating the actions of various components. The crimping mechanism 2 includes upper and lower crimping molds and a mold driving assembly. The upper mold is connected to the mold driving assembly, and the lower mold is fixed on the reference platform at the front of the mounting box 1. The positioning and guiding structure consists of guide posts and positioning blocks. The guide posts ensure precise alignment when the upper and lower molds are closed. When the electrical control unit receives the crimping command, the power supply device delivers pressure to the mold driving assembly, driving the upper mold to move downwards. It cooperates with the lower mold to apply a preset pressure to the terminal and wire harness placed on the positioning block, so that the terminal tightly wraps the wire harness conductor, completing the crimping. It should be noted that the above are all existing structures and will not be described in detail here. The front end of the mounting box 1 is fixedly connected to a mounting plate 3, and also includes:
[0022] The guide component 4, located inside the mounting plate 3, adjusts and precisely positions the feeding component 5 to ensure stable delivery and crimping of the wire harness terminal 505, preventing the feeding component 5 from shifting or shaking during movement, and completing the feeding, crimping, and unloading processes of the wire harness terminal 505.
[0023] The feeding component 5, located at the rear end of the outer wall of the slide plate 403, can stably clamp the wire harness terminal 505 and accurately connect it to the crimping station, ensuring that the terminal and the wire harness are in the preset position during crimping, reducing errors from manual feeding, and improving crimping efficiency and quality stability.
[0024] The guide assembly 4 includes fixing blocks 401 fixedly connected to the left and right sides of the inner wall of the mounting plate 3. A first electric push rod 402 is mounted on the inner wall of each fixing block 401, providing an installation reference for the first electric push rod 402. A slide plate 403 is fixedly connected to the drive end of each of the two first electric push rods 402. First guide rails 404 are slidably connected to the left and right sides of the bottom of the slide plate 403. The bottoms of the two first guide rails 404 are fixedly connected to the inner wall of the mounting plate 3. Mounting blocks 405 are fixedly connected to the upper and lower sides of the outer wall of the slide plate 403. A second electric push rod 406 is mounted on the inner wall of each of the two mounting blocks 405. A mounting frame 408 is fixedly connected to the drive end of each of the two second electric push rods 406. Second guide rails 407 are slidably connected to the protrusions on the upper and lower sides of the outer wall of the mounting frame 408. The outer walls of the two second guide rails 407... All components are fixedly connected to the outer wall of the slide plate 403. During operation, the first electric push rod 402 and the second electric push rod 406 are activated by the PLC controller. During feeding, the drive end of the second electric push rod 406 pushes the mounting frame 408 to slide to the left on the second guide rail 407. After feeding is completed on the feeding assembly 5, the second electric push rod 406 drives the mounting frame 408 to slide to the right. When the wire harness terminal 505 is aligned with the crimping mechanism 2, the drive end of the first electric push rod 402 pushes the slide plate 403 to slide on the first guide rail 404, so that the feeding assembly 5 clamps the wire harness terminal 505 for crimping. After crimping is completed, the first electric push rod 402 drives the slide plate 403 and the feeding assembly 5 to reset. The second electric push rod 406 then drives the feeding assembly 5 to slide to the right and repeats the operation to crimp the second wire harness terminal 505 that needs to be crimped.
[0025] The feeding assembly 5 includes a motor 501 mounted on the top of the mounting frame 408. The mounting frame 408 provides overall support for the motor 501. A threaded rod 502 is fixedly connected to the drive end of the motor 501. The other end of the threaded rod 502 is rotatably connected to the inner wall of the mounting frame 408. Clamping plates 503 are threadedly connected to both the upper and lower sides of the threaded rod 502. Multiple clamping holes 504 are opened at opposite ends of the outer walls of the two clamping plates 503. A wire harness terminal 505 is provided on the inner wall of the clamping hole 504 formed by the closing of the opposite ends of the two clamping plates 503. After receiving the command from the PLC control unit, the motor 501 starts and transmits power to the threaded rod 502 fixed to it, driving the threaded rod 502 along its own... The motor 501 rotates along the axis of the threaded rod 502. Since the threads on the upper and lower sides of the threaded rod 502 rotate in opposite directions and are threadedly connected to the upper and lower clamping plates 503 respectively, the rotation of the threaded rod 502 will drive the two clamping plates 503 to move relative to each other or in opposite directions along the axis of the threaded rod 502. When it is necessary to clamp the wire harness terminal 505, the motor 501 drives the threaded rod 502 to rotate in the forward direction, so that the two clamping plates 503 move closer to each other until the clamping holes 504 at their opposite ends are closed, forming a clamping space that matches the shape of the wire harness terminal 505, and stably clamping the wire harness terminal 505. When it is necessary to release the terminal, the motor 501 drives the threaded rod 502 to rotate in the reverse direction, causing the two clamping plates 503 to separate in opposite directions, releasing the clamping of the terminal.
[0026] Working principle: During the feeding stage, the PLC controller sends a command to the second electric push rod 406, whose drive end pushes the mounting frame 408 to slide to the left along the second guide rail 407, so that the feeding assembly 5 reaches the feeding station and places the wire harness terminal 505 to be processed into the clamping hole 504 of the lower clamping plate 503 in sequence. The motor 501 is then started, driving the threaded rod 502 to rotate forward, causing the two clamping plates 503 to move closer to each other until the clamping hole 504 closes, stably clamping the wire harness terminal 505 to be crimped. After the terminal is clamped, the second electric push rod 406 moves in the opposite direction, causing the mounting frame 408 to slide to the right along the second guide rail 407. When the wire harness terminal 505 is aligned with the positioning block of the crimping mechanism 2, the PLC controller triggers the first electric push rod 402, whose drive end pushes the slide plate 403 along the first guide rail 407. 4. Sliding, driving the feeding component 5 and the clamped wire harness terminal 505 to move towards the crimping station until the terminal is accurately placed on the positioning block. Then, the electrical control unit sends a crimping command to the mold drive component of the crimping mechanism 2. The pneumatic pump delivers stable pressure to the drive component, driving the upper mold to move downward. It cooperates with the lower mold to apply a preset pressure to the terminal and wire harness, so that the terminal tightly wraps the wire harness conductor, completing the crimping. The mold drive component drives the upper mold to reset. The first electric push rod 402 pulls the slide plate 403 in the opposite direction, causing the feeding component 5 to disengage from the crimping station. The operation is repeated to complete the crimping of the wire harness terminal 505 on the clamping hole 504. When the crimping of the wire harness terminal 505 on the clamping plate 503 is completed, the motor 501 drives the threaded rod 502 to rotate in the opposite direction, and the clamping plate 503 separates from each other, releasing the clamping of the crimped terminal and completing the unloading.
