[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model has the following advantages:
[0019] 1. In this utility model, the wire harness is pulled to the upper end of the movable slide plate inside the control box by the wire feeding wheel and the wire feeding port. After the wire harness is pressed down by the fourth electric push rod pushing the force plate, the first motor drives the lead screw to rotate, causing the movable slide plate to move to one side, thereby straightening and pulling out the wire harness. After pulling out a certain distance, the first electric push rod presses down the pressure plate to press the wire harness down, and the third electric push rod pushes the cutter down to cut the wire harness, realizing the fixed-distance cutting of the headphone wire harness, reducing the need for manual pulling and measuring of the length before cutting, making the work efficiency faster, and the cutting length more accurate and stable.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0029] Please see Figures 1-4This utility model provides a wire harness cutting device for headphone production, including an operation box 1 with an open front end, facilitating operation and timely response by the operator. A side box 2 with an upper and outer opening is connected to one side of the operation box 1, allowing observation of the number of wire harnesses in the internal wire feeding reel 3. A controller 121 is mounted on the outside of the side box 2, facilitating operation of the electrical components within the device. Different models can be purchased externally as needed, simplifying operation. The connection between the operation box 1 and the side box 2 is designed with... The wire harness is passed through the through-hole 4 for cutting. The side box 2 is equipped with a detachable wire feeding wheel 3, which can release the wound wire harness from the top for cutting. The inner wall of the operation box 1 is equipped with a scale 111, which makes it easy to measure the cutting distance during cutting, resulting in better measurement effect and accuracy. The operation box 1 is equipped with a collection box 13 at the lower end of the lead screw 14, so that after the wire harness is cut, it can fall directly into the collection box 13 for collection, thereby avoiding and reducing subsequent collection time and making the work more efficient.
[0030] Inside the control box 1, a lead screw 14 is rotatably mounted on both sides of the wire feeding port 4, and a slide rod 112 is fixedly mounted. A first motor 15 is installed on one end of the control box 1 and connected to the lead screw 14. A movable slide plate 16 is installed inside the control box 1. The movable slide plate 16 has threaded holes 17 and sliding holes 113 on both sides, which are connected to the lead screw 14 and slide rod 112 respectively. When the first motor 15 drives the lead screw 14 to rotate, the movable slide plate 16 moves left and right through the threaded holes 17, thereby adjusting the length of the wire harness cutting, reducing the need for manual straightening, and improving accuracy. The sliding connection between the sliding holes 113 and the slide rod 112 facilitates the support and movement of the movable slide plate 16. A mounting bracket 18 is provided at the upper end of the movable slide plate 16. The mounting bracket 18 has a force-bearing plate 110 inside, and a fourth electric push rod 19 is installed at the top of the mounting bracket 18 and connected to the force-bearing plate 110. This allows the fourth electric push rod 19 at the top to push the force-bearing plate 110 downward when the wire harness is placed on the upper end of the movable slide plate 16, thus pressing the wire harness down and preventing it from becoming loose or unstable when pulled. A cutting block 10 is installed inside the control box 1 near the wire release port 4. The upper surface of the cutting block 10 has a recessed cutting groove to facilitate cutting when the upper cutter 12 contacts the cutting block 10. A second electric push rod 9 is installed on the bottom plate of the control box 1 and connected to the cutting block 10. When the second electric push rod 9 moves the cutting block 10 up and down, the height of the cutting block 10 can be adjusted so that the cutting block... When the 10 moves downwards, the side sliding plate 16 moves to one side, making it easier to place the wire harness on the upper surface of the sliding plate 16 when it is on one side. A third electric push rod 11 is installed at the top of the control box 1, and the output end of the third electric push rod 11 passes through the top of the control box 1 and is connected to a cutter 12 located at the upper end of the cutting block 10. The third electric push rod 11 can drive the cutter 12 to move up and down, thereby cooperating with the up and down movement of the lower cutting block 10, so that the sliding plate 16 can move left and right easily when passing by, reducing interference. When the second electric push rod 9 pushes the cutting block 10 upwards and the third electric push rod 11 pushes the cutter 12 downwards, the wire harness can be cut. The lower end of the control box 1 near the wire release port 4 is supported by a support rod 5. The device is equipped with a placement plate 6, with a lower pressure plate 8 installed at the top of the placement plate 6. A first electric push rod 7 is installed at the top of the operation box 1, and the output end of the first electric push rod 7 passes through the operation box 1 and connects to the lower pressure plate 8. This allows the wire harness to be pressed down when the wire harness is placed on the top of the placement plate 6, thus pressing the lower pressure plate 8 firmly. This ensures that the wire harness on the placement plate 6 does not loosen after cutting. Furthermore, a certain length is left between the placement plate 6 and the cutting block 10, allowing the moving slide plate 16 to be moved to the side and the wire harness placed on top for repeated cutting. A rubber layer is provided on the upper surfaces of the placement plate 6 and the force plate 110, and on the lower surfaces of the lower pressure plate 8 and the force plate 110. The rubber layer reduces damage to the wire harness when it is pressed.Furthermore, increased friction makes the wire harness more stable during placement.
[0031] Please see Figure 2 and Figure 3 The front and rear side walls of the side box 2 are respectively equipped with a through-rotating block 114 and a limiting rotating block 115 via bearings. A rectangular rotating rod 116 is inserted between the through-rotating block 114 and the limiting rotating block 115, so that the through-rotating block 114 has a through rectangular hole in the middle, and the limiting rotating block 115 has a rectangular groove inward, so that the rotating rod 116 can pass through the through-rotating block 114 and the limiting rotating block 115 to connect, thereby positioning the rotating rod 116 vertically, and the limiting rotating block 115 can drive the rotating rod 116 to rotate during the rotation. The inside of the wire feeding wheel 3 has a limiting ring 118 outside the through-hole, which is slidably connected to the rotating rod 116. Several A positioning screw hole 119 is provided, and a fixing bolt 120 is provided at the through hole at the upper end of the limiting ring 118 to connect with the positioning screw hole 119. With the fixing bolt 120 rotating and connected to the positioning screw hole 119 through the through hole, the wire feeding wheel 3 can be fixed to the upper end of the rotating rod 116 through the limiting ring 118. Multiple wire feeding wheels 3 can be placed so that multiple groups of wire harnesses can be cut at one time, making the work efficiency faster. A second motor 117 is installed on the outside of the side box 2, and the output end of the second motor 117 is connected to the closed end of the limiting rotating block 115. The second motor 117 can drive the limiting rotating block 115 to rotate, causing the inner rotating rod 116 to rotate, which makes the wire feeding wheel 3 rotate, speeding up the wire feeding rate and making the pulling faster.
[0032] Working principle: In use, first connect the first electric push rod 7, the second electric push rod 9, the third electric push rod 11, the first motor 15, the fourth electric push rod 19, and the second motor 117 to the controller 121 and connect them to an external power supply. During use, pull out the wire harness from the outside of the wire feeding wheel 3, allowing it to pass through the wire feeding port 4 and be placed on the upper end of the moving slide plate 16. The fourth electric push rod 19 pushes down the force plate 110 to press the wire harness firmly. This causes the second motor 117 to drive the rotating rod 116 to accelerate the rotation of the wire feeding wheel 3 to feed the wire. The first motor 15 drives the lead screw 14 to rotate, pulling the moving slide plate 16 to one side. After the wire harness is pulled to the cutting length, the first electric push rod 7 pushes down the lower pressure plate 8 and the placement plate 6 together to press the other end of the wire harness firmly. Then, the second electric push rod 9 and the third electric push rod... 11. The cutting block 10 and the cutter 12 are pushed inward to cut the wire harness. After cutting, the fourth electric push rod 19 pulls the force plate 110 upward to release the wire harness, which falls into the storage box 13. Then, the second electric push rod 9 and the third electric push rod 11 return the cutting block 10 and the cutter 12 to their original positions. The moving slide plate 16 is then moved to the placement plate 6 and the excess wire harness ends are placed on the moving slide plate 16 for pressing. When the moving slide plate 16 is pulled outward, the lower pressure plate 8 loosens the wire harness and presses it back up when cutting. This cutting process is repeated. When replacing the wire feeding wheel 3 after cutting, the fixing bolt 120 is turned out, and the rotating rod 116 is pushed outward through the rotating block 114 to pull it outward. The wire feeding wheel 3 can then be removed and replaced from the inner pull-out end, thus completing the work.
