[0036] like Figure 1-4 As shown, this application provides a wire harness feeder, including a support base 1, a wire feeding assembly 3, a power drive box 4, a magnetic induction proximity switch 5, a wire assembly 6, and a buffer assembly 7. A wire feeding frame 2 is fixed on the support base 1. The wire feeding assembly 3 is mounted on the support base 1 and is used to drive the cable reel to rotate and feed the wire. The power drive box 4 is fixed on the support base 1 and is used to connect the power supply and control the operation of the wire feeding assembly 3. The magnetic induction proximity switch 5 is fixed on the wire feeding frame 2 and is used to sense the moving speed of the cable and transmit the signal to the power drive box 4. The wire assembly 6 is mounted on the wire feeding frame 2 and is used to limit the displacement of the cable. The buffer assembly 7 is located between the cable feeder 2 and the support base 1. The buffer assembly 7 is used to buffer and protect the cable. The cable feeder is fed by this device. The magnetic induction proximity switch 5 senses the moving speed of the cable and transmits the signal to the power drive box 4. The power drive box 4 controls the feeding speed of the cable feeding assembly 3. When the cable is subjected to too much traction force from the cable opener, the speed of the cable will increase. At this time, the power drive box 4 controls the cable feeding assembly 3 to increase the feeding speed. At the same time, the buffer assembly 7 will buffer the tension on the cable, effectively preventing the cable from knotting and the insulation from shrinking due to excessive tension. This increases the tension bearing range of the cable and shortens the adjustment time of the cable opener.

[0037] like Figure 1-4 As shown, the cable feeding assembly 3 includes a motor 31 and a drive shaft 32. The motor 31 is fixed on the support base 1, and one end of the drive shaft 32 is connected to the output end of the motor 31. The motor 31 drives the drive shaft 32 to rotate. In use, the cable reel is fixed on the drive shaft 32, and the drive shaft 32 rotates to drive the cable reel to rotate.

[0038] like Figure 4As shown, the power drive box 4 includes a power switch 41 and a speed controller 42. The power switch 41 is used to control the power supply, and the speed controller 42 is used to receive the signal from the magnetic induction proximity switch 5 and control the speed of the motor 31 according to the signal from the magnetic induction proximity switch 5.

[0039] like Figure 4 As shown, the power drive box 4 also includes a forward / reverse switch 43, which is used to control the forward or reverse rotation of the motor 31, thereby controlling the forward or reverse rotation of the drive shaft 32, so that the cable reel fixed on the drive shaft 32 can rotate to unwind or rewind the cable. The excess cable can be rewound after unwinding according to the actual situation.

[0040] like Figure 4 As shown, the power drive box 4 also includes a fuse 44. When the current exceeds the rated value of the fuse 44, the fuse element of the fuse 44 will melt due to overheating, thereby cutting off the current in the circuit to protect the equipment from overload and short circuit faults.

[0041] like Figure 1 and Figure 2 As shown, the conductor assembly 6 includes an upper fixed seat 61, a lower fixed seat 62, a first infeed guide rod 63, and a second infeed guide rod 64. The upper fixed seat 61 and the lower fixed seat 62 are fixedly mounted on the cable feeder 2 from top to bottom. One end of the first infeed guide rod 63 and one end of the second infeed guide rod 64 are fixedly connected to the upper fixed seat 61, and the other end of the first infeed guide rod 63 and the other end of the second infeed guide rod 64 are fixedly connected to the lower fixed seat 62. The first infeed guide rod 63 and the second infeed guide rod 64 are arranged parallel to each other. In use, the cable on the cable drum is pulled out and passes through the gap between the first infeed guide rod 63 and the second infeed guide rod 64, which enables the cable to be transported in an orderly manner and prevents the cable from deviating.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, a first roller shaft 8 is fixed on the cable feeder 2, and a first winding roller 9 is rotatably mounted on the first roller shaft 8. The first winding roller 9 can change the cable feeding direction and turn the cable.

[0043] like Figure 1 and Figure 3As shown, the buffer assembly 7 includes a first guide shaft 71, a second guide shaft 72, a movable seat 73, a second roller shaft 74, a second winding roller 75, a first spring 76, a second spring 77, a third spring 78, and a fourth spring 79. One end of the first guide shaft 71 and one end of the second guide shaft 72 are fixedly connected to the wire feeder 2, and the other ends of the first guide shaft 71 and the second guide shaft 72 are fixedly connected to the support base 1. The movable seat 73 is movably sleeved on the first guide shaft 71 and the second guide shaft 72. One end of the second roller shaft 74 is fixedly connected to the movable seat 73. The second winding roller 75 is rotatably mounted on the second roller shaft 74. The first spring 76 and the second spring 77 are both movably sleeved on the first guide shaft 71, and the third spring 78 and the fourth spring 79 are both movably sleeved on the second guide shaft 72. Spring 78 and the fourth spring 79 cooperate to buffer the up-and-down movement of the movable seat 73. Specifically, in use, the cable passes through the gap between the first inlet guide rod 63 and the second inlet guide rod 64, passes around the second winding roller 75 and the first winding roller 9, and then connects to the wire feeding system of the wire cutter. The wire feeding system of the wire cutter pulls the cable. When the cable is pulled, it becomes taut. At this time, the movable seat 73 is pulled upward and moves upward. The first spring 76 and the third spring 78 contract, and the second spring 77 and the fourth spring 79 extend, buffering the movable seat 73. The cable is also buffered when it is pulled, avoiding damage to the cable due to sudden traction. When the traction force on the cable disappears, the first spring 76 and the third spring 78 extend, the second spring 77 and the fourth spring 79 contract, the movable seat 73 returns to its original position, and the second winding roller 75 returns to its original position.

[0044] like Figure 1As shown, the movable seat 73 includes a first movable block 731, a second movable block 732, and a connecting block 733. The first movable block 731 is movably sleeved on the first guide shaft 71, the second movable block 732 is movably sleeved on the second guide shaft 72, and the connecting block 733 is fixedly connected to the first movable block 731 and the second movable block 732. One end of the second roller shaft 74 is fixedly mounted on the connecting block 733. One end of the first spring 76 abuts against the wire feeder 2, and the other end of the first spring 76 abuts against the top of the first movable block 731. One end of the second spring 77 abuts against the bottom of the first movable block 731. The other end of spring 77 abuts against support base 1, one end of third spring 78 abuts against wire feeder 2, the other end of third spring 78 abuts against the top of second movable block 732, one end of fourth spring 79 abuts against the bottom of second movable block 732, and the other end of fourth spring 79 abuts against support base 1. Specifically, first spring 76 and second spring 77 act on first movable block 731, third spring 78 and fourth spring 79 act on second movable block 732, and connecting block 733 connects first movable block 731 and second movable block 732 into a whole to form movable base 73.

[0045] like Figure 1 and Figure 3 As shown, both the first winding roller 9 and the second winding roller 75 are provided with multiple annular winding grooves. The cable is wound along the annular winding grooves on the first winding roller 9 and the second winding roller 75. During winding, the cable can be wound alternately in a figure-eight pattern on the first winding roller 9 and the second winding roller 75 to ensure orderly cable delivery.

[0046] Working principle:

[0047] In use, the cable reel is fixed to the drive shaft 32. The cable is pulled out from the reel and passed through the gap between the first inlet guide rod 63 and the second inlet guide rod 64. Then, the cable is wound alternately in a figure-eight pattern to prevent it from going around the second winding roller 75 and the first winding roller 9. Finally, the cable leaves the second winding roller 75 and connects to the cable feeding system of the cable opener. The cable is then pulled and fed by the cable feeding system of the cable opener. The power switch 41 is pressed to turn on the power. The magnetic induction proximity switch 5 senses the moving speed of the cable and transmits the signal to the speed controller 42 of the power drive box 4. The speed controller 42 adjusts the speed according to the magnetic induction. The signal from the proximity switch 5 controls the speed of the motor 31. When the cable is subjected to excessive traction force from the cable cutter, the cable speed will increase. At this time, the speed of the motor 31 will increase, thereby increasing the unwinding speed and reducing the tension on the cable. Since the cable cutter performs cable cutting and trimming intermittently, the cable will be subjected to sudden changes in traction force. When the cable is subjected to traction force, the buffer component 7 can buffer the traction force on the cable, thus protecting the cable and effectively preventing excessive tension from causing the cable to knot or the insulation to shrink back. This increases the cable's tension tolerance range and shortens the adjustment time of the cable cutter.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
