Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness production and processing technology, and in particular to a wire stripping device for wire harness production. Background Technology
[0002] A wire stripper is a machine used to separate the plastic outer sheath of wires from their metal core. It is widely used in the electronics, communications, and automotive industries. Wire harnesses are important components in automobiles and other mechanical equipment used to transmit power and signals. They are mainly composed of wires, terminals, connectors, and sheaths, and serve as the bridge and link for the operation of vehicle electrical components.
[0003] However, existing wire stripping devices typically use blades to continuously cut the outer sheath. This method, due to the bending of some wires in the harness, easily scratches the internal copper wires. At the same time, the bent wires cannot be corrected in time, which may lead to breakage or blockage during subsequent wire feeding, resulting in low stability. In addition, the outer rubber sheath after separation is difficult to recycle in time, and the copper wires that have been stripped are not coated with antioxidants in time, which leads to contact with air or moisture during subsequent production processes, resulting in rust after packaging and reducing the quality of the product in subsequent use.
[0004] Therefore, this application provides a wire stripping device for wire harness production to meet the requirements. Utility Model Content
[0005] The technical problem this utility model aims to solve is to provide a wire stripping device for wire harness production. This addresses the shortcomings of existing methods that typically involve continuous cutting with blades on the outer sheath. In such cases, the wire harness may be bent, easily damaging the internal copper wires. Furthermore, the bent wires are not corrected in time, potentially leading to breakage or blockage during subsequent wire feeding. Additionally, the lack of timely application of antioxidants to the stripped thick copper wires allows them to come into contact with air or moisture during production, resulting in rust after packaging and reducing the quality of the product.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wire stripping device for wire harness production, comprising a wire stripping machine, an inlet plate installed on one side of the wire stripping machine, a push roller installed on the inner bottom side of the wire stripping machine, an outlet installed on the other side of the wire stripping machine, a receiving box provided on the inner bottom side of the wire stripping machine, an electric slide rail installed on the inner back side of the wire stripping machine, an electric cutter installed at the front end of the electric slide rail, and an outlet sleeve installed on the back side of the wire stripping machine; a straightening component installed on the inner back side of the wire stripping machine, the straightening component being used to straighten bent wire harnesses; a cutting component installed on the inner back side of the wire stripping machine, the cutting component being used to cut the stripped wire harness; a recycling component installed on the inner back side of the wire stripping machine, the recycling component being used to recycle the stripped rubber sheath; and a coating component installed at one end of the outlet sleeve, the coating component being used to apply an antioxidant to the stripped copper wire.
[0007] Optionally, the straightening component includes an outer sleeve, which is installed on the inner side of the back of the wire stripping device. An inlet circular plate is installed at one end of the outer sleeve, a heating ring is installed on the inner wall of the outer sleeve, and a straightening sleeve is installed on the inner wall of the outer sleeve. An inlet groove is provided at one end of the straightening sleeve.
[0008] Optionally, the inlet circular plate is configured as a frustum shape, the heating ring is configured as multiple sets and is adjacent to the regular sleeve, and the inlet groove is configured as a concave shape.
[0009] Optionally, the cutting assembly includes a base, one end of which is provided with a mounting rod, and a blade is sleeved on the middle of the mounting rod.
[0010] Optionally, the recycling component includes a mounting base, which is installed on the inner bottom of the wire stripping device. A pulling roller is mounted on the mounting base. A first guide plate and a second guide plate are provided on one side of the pulling roller and the mounting base. A cutter is provided at one end of the second guide plate. An auxiliary discharge shaft is installed between the second guide plate and the cutter.
[0011] Optionally, the first guide plate and the second guide plate are inclined at an angle of 45°. One end of the first guide plate is close to the pulling roller, and one end of the second guide plate is set in the mounting base and the other end is connected to a cutter, which is semi-circular.
[0012] Optionally, the coating assembly is equipped with a sponge ring, which is installed at the inlet end of the outlet sleeve. The sponge ring is also equipped with a liquid inlet box, and a liquid inlet hole is provided on the surface of the sponge ring near the inner side of the liquid inlet box. A liquid inlet pipe is installed in the liquid inlet hole.
[0013] Optionally, the sponge ring is circular, the liquid inlet holes are configured in multiple groups and arranged in an array on the surface of the sponge ring, and a liquid inlet pipe is connected to one side of the liquid inlet box.
[0014] Compared with the prior art, this utility model has at least the following beneficial effects:
[0015] In the above solution, by setting up a straightening component, the wire harness is preheated and then straightened, making the bent parts straight, which is more conducive to the subsequent stripping work and prevents the bent wire harness from breaking during stripping. At the same time, by setting up a cutting component, the cutting position can be adjusted by moving left and right on the electric slide rail, which makes it easy to adjust the cutting length of the wire harness. Finally, the wire harness is quickly discharged from the discharge port, improving the convenience of use.
[0016] By setting up a recycling component, the stripped rubber outer layer is recycled. The rubber outer layer is pulled and transported by a pulling roller, achieving rapid separation of the rubber outer layer and copper wire. A cutting blade is used to make only a small opening at the front end, and then the rubber outer layer is separated by pulling. The stripped rubber outer layer is pushed from the other end of the pulling roller and falls into the receiving box. This method is not only highly efficient, but also prevents the blade from scratching the copper wire, has high recycling efficiency, reduces labor costs, and makes it more efficient and faster.
[0017] By setting up a coating component, the stripped copper wire passes through a sponge ring. The liquid inlet box inside the sponge ring transmits the antioxidant to the liquid inlet hole through the liquid inlet pipe. The antioxidant penetrates into the interior of the sponge ring through the liquid inlet hole, uniformly coating the surface of the copper wire with antioxidant. This prevents the stripped copper wire from oxidizing in a short time when it encounters moisture in the air, improving the safety and stability of the wire harness in later use, effectively reducing production costs and minimizing workpiece wear.

[0031] like Figures 1 to 5 As shown, an embodiment of this utility model provides a wire stripping device for wire harness production, including a wire stripping device 1. A wire inlet plate 10 is installed on one side of the wire stripping device 1, a push roller 11 is installed on the inner bottom side of the wire stripping device 1, a wire outlet 12 is installed on the other side of the wire stripping device 1, a receiving box 13 is provided on the inner bottom side of the wire stripping device 1, an electric slide rail 14 is installed on the inner back side of the wire stripping device 1, an electric cutter 15 is installed at the front end of the electric slide rail 14, and a wire outlet sleeve 16 is installed on the back side of the wire stripping device 1. A straightening component 2 is installed on the inner back side of the wire stripping device 1, used to straighten bent wire harnesses. A cutting component 3 is installed on the inner back side of the wire stripping device 1, used to cut the stripped wire harness. A recycling component 4 is installed on the inner back side of the wire stripping device 1, used to recycle the stripped rubber sheath. A coating component 5 is installed at one end of the wire outlet sleeve 16, used to coat the stripped copper wire with an antioxidant.
[0032] like Figure 1 and Figure 2 As shown, the straightening component 2 includes an outer sleeve 20, which is installed on the inner side of the back of the wire stripping device 1. An inlet circular plate 21 is installed at one end of the outer sleeve 20. A heating ring 22 is installed on the inner wall of the outer sleeve 20. A straightening sleeve 23 is installed on the inner wall of the outer sleeve 20. An inlet groove 24 is opened at one end of the straightening sleeve 23. The inlet circular plate 21 is frustoconical. Multiple sets of heating rings 22 are arranged adjacent to the straightening sleeve 23. The inlet groove 24 is concave.
[0033] In this embodiment, as the process continues, the softened wire harness enters the straightening sleeve 23 through the concave inlet groove 24. Since the inner diameter of the straightening sleeve 23 is the same as that of the wire harness, the concave inlet groove 24 facilitates the wire harness to enter the straightening sleeve 23 more smoothly.
[0034] like Figure 3 As shown, the cutting assembly 3 includes a base 30, one end of which is provided with a mounting rod 31, and a blade 32 is sleeved on the middle of the mounting rod 31.
[0035] In this embodiment, the wire harness is pushed into the blade 32, and the blade 32 works on both sides of the wire harness, opening cutting edges on both sides. Since the cutting edge opening is only made on both sides, after the wire harness is regulated, and the distance inside the cutting edge is greater than the diameter of the copper wire, even if some rubber thickness is left, the rubber can still be separated by the cutter 44, and there will be no direct and continuous contact with the surface of the copper wire.
[0036] like Figure 3 and Figure 4 As shown, the recycling component 4 includes a mounting base 40, which is installed on the inner bottom of the wire stripping device 1. A pulling roller 41 is mounted on the mounting base 40. A first guide plate 42 and a second guide plate 43 are provided on one side of the pulling roller 41 and the mounting base 40. A cutter 44 is provided at one end of the second guide plate 43. An auxiliary discharge shaft 45 is installed between the second guide plate 43 and the cutter 44. The first guide plate 42 and the second guide plate 43 are inclined at an angle of 45°. One end of the first guide plate 42 is close to the pulling roller 41. One end of the second guide plate 43 is located in the mounting base 40, and the other end is connected to the cutter 44, which is semi-arc-shaped.
[0037] In this embodiment, since the cutter 44 can only pass through copper wires, the wire harness sheath is continuously pushed to both sides by the auxiliary discharge shaft 45, and the wire harness sheath is discharged by the pull roller 41.
[0038] like Figure 5 As shown, the coating component 5 is equipped with a sponge ring 50, which is installed at the inlet end of the cable sleeve 16. The sponge ring 50 is equipped with a liquid inlet box 51. A liquid inlet hole 52 is opened on the surface of the sponge ring 50 near the inner side of the liquid inlet box 51. A liquid inlet pipe 53 is installed in the liquid inlet hole 52. The sponge ring 50 is circular, and the liquid inlet holes 52 are set in multiple groups and arranged in an array on the surface of the sponge ring 50. A liquid inlet pipe 53 is connected to one side of the liquid inlet box 51.
[0039] In this embodiment, the antioxidant is output through the inlet pipe 53 inside the sponge ring 50. The inlet holes 52 inside the inlet box 51 are evenly distributed inside the inlet box 51 and are evenly permeated into the sponge ring 50 through the inlet holes 52. Since the inner diameter of the sponge ring 50 is the same as the outer diameter of the copper wire, when the copper wire passes through, the surface of the copper wire is completely coated with antioxidant liquid.
[0040] The working principle of the technical solution provided by this utility model is as follows:
[0041] First, the worker places the wire harness into the infeed tray 10 via a conveyor belt. Then, the push roller 11 is activated to clamp the wire harness and push it to the left. The wire harness enters the outer sleeve 20. Upon entering, the heating ring 22 first heats the rubber on the surface of the wire harness and the internal copper wire to soften the wire harness. Then, as it continues to advance, the softened wire harness enters the straightening sleeve 23 through the concave infeed groove 24. Since the inner diameter of the straightening sleeve 23 is the same as that of the wire harness, the straightening sleeve 23 can straighten the bent parts of the wire harness to make them straighter. Then, when one end of the wire harness exits the straightening sleeve 23;
[0042] At this point, the blade 32 makes openings on both sides of the wire harness, which then enters the cutter 44. Since the cutter 44 can only access the copper wire, it also peels off the rubber on the surface of the wire harness, separating the copper wire from the surface rubber. The upper and lower rubber sheaths are separated by the guide of the auxiliary discharge shaft 45. As the wire harness continues to advance, it continues to enter the pulling roller 41 through the guide of the first guide plate 42 and the second guide plate 43. Both sets of pulling rollers 41 rotate inward, clamping and pulling the rubber sheath outward, continuously pulling the rubber sheath apart. When the wire harness is cut by the electric cutter 15, the detached rubber falls into the receiving box 13. As the copper wire continues to advance, it reaches the sponge ring 50. The sponge ring 50 transmits the antioxidant liquid through the liquid inlet pipe 53. The antioxidant is indirectly pumped through an external liquid pump. The antioxidant liquid enters the liquid inlet box 51. Since the liquid inlet box 51 has multiple sets of liquid inlet holes 52, the liquid enters and permeates into the sponge ring 50 through the multiple sets of liquid inlet holes 52. When the copper wire passes through the sponge ring 50, the sponge ring 50 coats the surface of the copper wire with antioxidant liquid. At this time, the copper wire is not easily oxidized, making it more resistant to oxidation and reducing the loss rate of subsequent workpiece production. After the coating is evenly applied, the copper wire enters the wire outlet sleeve 16. Then, the electric cutter 15 cuts the wire according to the required length of the wire harness while moving left and right on the electric slide rail 14. The cut copper wire slides down through the wire outlet 12 and is collected.
[0043] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
