Description

Technical Field

[0001] This utility model relates to the field of automotive wheel speed sensor wiring harness technology, specifically a mechanism for automatically straightening and separating two strands of wire at a specified interval. Background Technology

[0002] The wheel speed sensor wiring harness is an important component of the automotive safety system. It is mainly used in the anti-lock braking system of automobiles. By monitoring the wheel speed in real time, it provides data support to the electronic control unit and ensures the stability of the vehicle during braking. In the production process of the wheel speed sensor wiring harness, the black and white double strands of the wire are straightened by hand, then the wires are separated by a certain distance, and then the wiring harness is clamped and sent to the next process.

[0003] However, this device has the following shortcomings:

[0004] 1. Currently, when separating the double strands, the method of manually straightening the threads is used. This method not only makes it difficult to straighten the threads, but also makes it impossible to determine the separation distance between the two strands, resulting in inaccurate placement of the black and white threads and making it inconvenient to accurately introduce them into the next process.

[0005] 2. When separating the two strands, the two strands need to be pulled in different directions. Therefore, the two strands will be subjected to a certain pulling force when separating them. Currently, it is difficult to buffer the pulling force on the two strands, which makes the wire harness easy to be damaged and broken. Utility Model Content

Trapezoidal blocks B that cooperate with trapezoidal blocks A are provided on one side of each of the two sets of movable rods.

[0009] Preferably, the trapezoidal block A and trapezoidal block B are provided with anti-slip pads on the side that are close to each other, which can increase the friction of the contact surface between trapezoidal block A and trapezoidal block B and enhance the resistance effect.

[0022] Please see Figure 1-4 The present invention provides an embodiment of a mechanism for automatically straightening and separating double-stranded wires at a specified interval, comprising a base 1 and a wire clamping mechanism 2. A buffer mechanism 3 is provided on one side of the wire clamping mechanism 2. A mounting shell 4 is provided on the top of the base 1. A front and rear motor 5 is provided on the top of the mounting shell 4. A mounting plate 6 is provided on the front and rear motor 5. A wire splitting motor 7 is provided on one side of the top of the mounting plate 6. A threaded rod 8 is threadedly connected to the output end of the wire splitting motor 7. A translation plate 9 is provided at the bottom of the threaded rod 8. Longitudinal guide rails are provided at both ends of the top of the front and rear motor 5. A slide table is provided at the bottom of the translation plate 9 to cooperate with the two sets of longitudinal guide rails for guiding the translation plate 9. When the translation plate 9 moves, it can drive the slide table to move along the longitudinal guide rails.

[0023] A transverse guide rail 10 is provided in the middle of the top of the mounting plate 6. Two sets of wire splitting claws 11 are slidably connected to the outer side of the transverse guide rail 10. The two sets of wire splitting claws 11 are slidably connected to the translation plate 9. Two sets of guide grooves 13 are provided on the top of the translation plate 9. Rollers 14 that slide in cooperation with the guide grooves 13 are provided on one side of the top of the two sets of buffer mechanisms 3. They can guide the wire splitting claws 11. When the wire splitting motor 7 drives the translation plate 9 to move, the rollers 14 can slide along the inner side of the guide grooves 13, thereby controlling the two sets of wire splitting claws 11 to move closer or further away from each other. A wire pulling claw 12 is provided on the top side of the mounting plate 6 away from the wire splitting motor 7. The wire pulling claw 12 is located inside the two sets of wire splitting claws 11.

[0024] The buffer mechanism 3 includes a buffer box 31, a guide rod 32, a guide wheel 33, a trapezoidal block A34, a movable rod 35, a trapezoidal block B36, and a spring 37. The buffer box 31 is located at the top of both ends of the wire clamping mechanism 2. The guide rod 32 is sleeved on one end of the two sets of buffer boxes 31 that are close to each other. The guide wheel 33 is provided on one end of the two sets of guide rods 32 that are close to each other. The trapezoidal block A34 is provided on one end of the two sets of guide rods 32 that are far apart from each other. The movable rod 35 is sleeved on one side inside the two sets of buffer boxes 31.

[0025] One side of each of the two sets of movable rods 35 is provided with a trapezoidal block B36 that cooperates with the trapezoidal block A34. Anti-slip pads are provided on the side of trapezoidal block A34 and trapezoidal block B36 that are close to each other, which can increase the friction of the contact surface between trapezoidal block A34 and trapezoidal block B36 and enhance the resistance effect. One end and one side of the buffer box 31 are provided with guide grooves, and sliders are slidably connected to the inner side of the two sets of guide grooves. The two sets of sliders are respectively connected to trapezoidal block A34 and trapezoidal block B36, which can guide trapezoidal block A34 and trapezoidal block B36 and improve the stability of the movement. Springs 37 are sleeved on the outer side of the two sets of movable rods 35 and the two sets of springs 37, which can buffer the pulling force when the wire harness is separated.

[0026] Working principle: When producing automotive wheel speed sensor wiring harnesses, this device first transports the wiring harness from the previous process to the wire clamping mechanism 2, where the wire clamping mechanism 2 clamps the wiring harness. At this time, the core wire is exposed outside the clamping claws. The core wire is clamped by the wire pulling claw 12. Then, the front and rear motors 5 are started to drive the mounting plate 6 to move backward, which can pull the core wire backward. Then, the wire pulling claw 12 is released, and the front and rear motors 5 control the wire pulling claw 12 to reset and clamp the core wire again to pull it backward. This process is repeated twice to straighten the core wire.

[0027] After the core wire is straightened, the base 1 is released. At this time, the two sets of wire-separating jaws 11 clamp the roots of the black and white core wires respectively. Then, the front and rear motors 5 and the wire-separating motor 7 are controlled to move together. The front and rear motors 5 can drive the two core wires to pull backward. The wire-separating jaws 11 can drive the threaded rod 8 to move forward. Then the threaded rod 8 drives the translation plate 9. At this time, the roller 14 can slide along the inner side of the guide groove 13 on the translation plate 9, thereby driving the two sets of wire-separating jaws 11 to move away from each other under the guidance of the transverse guide rail 10, separating and bending the core wires, thus completing the wire-separating operation of the double-stranded wire. According to the wire-separating requirements, the core wires can be separated to the set spacing.

[0028] When the device is splitting the wires, after the two sets of wire clamping mechanisms 2 clamp the core wires, the two sets of guide wheels 33 can also clamp the core wires and guide them. When splitting two core wires, the core wires will be pulled to both sides. At this time, the guide wheels 33 can be pushed to overcome the spring movement of the spring 37 and buffer the damage caused by the pulling of the wire harness. Then the guide wheels 33 drive the trapezoidal block A34, so that the inclined surface of the trapezoidal block A34 can slide along the inclined surface of the trapezoidal block B36. The friction during the sliding can play a damping role. At the same time, the trapezoidal block B36 can also overcome the elastic force of the spring 37 and slide to one side, improving the buffering effect on the wire harness.
