Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a wire harness end stripping device. Background Technology

[0002] In automobile manufacturing workshops, from complex engine wiring harnesses to door and window control wiring harnesses, the stripping can be completed quickly and accurately, laying a solid foundation for subsequent connections and assembly, and assisting in the electrical construction of the entire vehicle. On electronic equipment production lines, the delicate and precise wiring harnesses inside mobile phones and computers are stripped at the ends to ensure stable signal transmission.

[0003] In the existing technology, some wire harnesses are key components for connecting various electrical devices, and their processing quality directly affects their performance. Stripping the wire harness ends is an important step in wire harness processing. Existing technology uses a motor to drive a blade to rotate and cut the outer sheath, which has a limited degree of automation. Furthermore, it requires frequent adjustments to equipment parameters for different specifications of wire harnesses, making the operation complex and the work efficiency extremely low. Uneven force can easily damage the wire core, making it difficult to meet the needs of large-scale production.

[0004] However, in actual use, it cannot quickly adjust to accurately strip wires of varying lengths inside a car; it also lacks adaptability to different specifications of wire harnesses in electronic devices due to frequent updates, making it difficult to flexibly switch operating modes, which seriously restricts production efficiency and product quality. In response to the above problems, a wire harness end stripping device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wire harness end stripping device, which aims to improve some of the problems in the prior art.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the sliding block moves on the slide rail, while the stepper motor drives the active rod to move, which in turn drives the driven wheel to move, which in turn drives the connecting rod to move, and then the follower block slides on the slide groove.

A belt 9 is sleeved on the outside of the drive wheel 8. The belt 9 is wrapped between the drive wheel 8 and the subsequent driven wheel 10 and meshes with the two wheels through the teeth. The belt 9 is sleeved on the outside of the drive wheel 8. The driven wheel 10 is fixedly connected to the outside of the belt 9. The driven rod 11 is fixedly connected to the inside of the driven wheel 10. A sliding assembly is fixedly connected to the outside of the driven rod 11. A support assembly is fixedly connected to the outside of the sliding block 5. The stepper motor 6 is fixedly connected to the outside of the sliding block 5. The sliding assembly includes a connecting rod 12, which is long and narrow.

[0037] At one end of the connecting rod 12, a follower block 13 is fixedly connected. The follower block 13 is square in shape and has a smooth surface. The follower block 13 is fixedly connected to the outside of the connecting rod 12. The outside of the connecting rod 12 is fixedly connected to the outside of the driven rod 11.

A blade 18 is fixedly connected to the outside of the concave plate 16. The blade 18 is a sharp triangle and is used to strip the wire harness. The follower block 13 is slidably connected to the outside of the slide groove 15. The follower block 13 can slide smoothly inside the slide groove 15.

[0038] Reference Figure 2 , Figure 3 , Figure 4 The cleaning mechanism includes a gas generator 19, to which a connecting pipe 20 is fixedly connected. The connecting pipe 20 is cylindrical with a certain wall thickness, providing good pressure resistance. It is also made of a flexible material, which facilitates installation according to the structural characteristics of the L-shaped plate 2 and the actual space layout. Multiple nozzles 21 are fixedly connected to the outside of the connecting pipe 20. The nozzles 21 are designed in the shape of a truncated cone with a sharp top and evenly distributed extremely fine air jet holes. These air jet holes are precision machined to ensure that the high-pressure cleaning gas generated by the gas generator 19 is ejected at a precise angle and with stable pressure, effectively cleaning the debris, dust and other impurities remaining in the stripped part of the wire harness. The gas generator 19 is fixedly connected to the outside of the L-shaped plate 2. A support block 22 is fixedly connected to the outside of the L-shaped plate 2. The support block 22 is a regular rectangular block, ensuring the overall structural stability.

[0039] Multiple brushes 23 are fixedly connected to the outside of the support block 22. The main body of the brush 23 is a slender cylindrical shape with closely arranged bristles. The length and distribution density are precisely calculated to cover the area of ​​the wire harness that needs to be cleaned in all directions. With the assistance of gas jet, it can more thoroughly clean stubborn stains on the surface of the wire harness. A connecting block 24 is fixedly connected to the outside of the L-shaped plate 2.

The positioning block 27 is slidably connected to the outside of the connecting block 24.

[0040] Working principle: First, the horizontally extended active rod 7 driven by the stepper motor 6 rotates, which drives the disc-shaped active wheel 8 fixed outside the active rod 7 to rotate. This causes the teeth on the edge of the active wheel 8 to mesh tightly with the belt 9 surrounding it, thereby driving the belt 9 to move. The belt 9 then drives the driven wheel 10 to rotate through the teeth, allowing it to slide smoothly in the groove 15 fixed outside the support plate 14. This allows the telescopic rod 17 to extend and retract within a certain range. The sharp triangular blade 18 fixed at its end approaches the wire harness under the action of the sliding block 5. As the sliding block 5 continues to move, the blade 18 contacts and cuts into the outer sheath of the wire harness, completing the stripping operation.

[0041] High-pressure cleaning gas is generated by the gas generator 19 in the cleaning mechanism connected to the outside of the L-shaped plate 2. It is transmitted to multiple truncated cone-shaped nozzles 21 through the cylindrical connecting pipe 20. The gas is sprayed out from the small air jet hole at the top of the nozzle 21 at a precise angle and stable pressure to clean the debris, dust and other impurities remaining in the stripped area. Meanwhile, multiple slender cylindrical brushes 23 fixed on the support block 22 further clean the stubborn stains on the surface of the wire harness with the assistance of the gas jet. This causes the cylinder 25 to drive the connecting rod 26, which in turn drives the cuboid positioning block 27 fixed on its outer surface to slide left and right outside the L-shaped connecting block 24, flexibly adjusting its position to meet the positioning requirements of different specifications of wire harnesses in the stripping and cleaning process.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
