[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, these technologies, methods, and equipment should be considered part of the specification.

[0032] like Figure 1-3 As shown, the utility model provides an automatic wire stripping device, which includes: a wire cutting mechanism, which is used to cut the insulation layer along the radial direction of the wire, and the wire cutting mechanism includes a fixed platform 1, an upper wire cutting blade 2, a lower wire cutting blade 3, a wire cutting elastic component 4, a top plate 5 and a pressing handle 6. The fixed platform 1 is located below the top plate 5 and is the base of the wire cutting mechanism. The cutting edges of the upper wire cutting blade 2 and the lower wire cutting blade 3 are relatively arranged between the fixed platform 1 and the top plate 5. The upper wire cutting blade 2 is a movable blade, and the lower wire cutting blade 3 is a fixed blade. The wire cutting elastic component 4 is vertically arranged between the fixed platform 1 and the top plate 5 and is located on the periphery of the upper wire cutting blade 2 and the lower wire cutting blade 3 (for example, Figure 1 and 3 On both sides shown), a pressing handle 6 is arranged above the top plate 5 for pressing the wire cutting elastic component 4 to drive the upper wire cutting blade 2 to reciprocate and cut the wire radially; a wire stripping mechanism, the wire stripping mechanism is used to strip the insulation layer along the axial direction of the wire, the wire stripping mechanism includes a mounting bracket 7, a wire stripping wheel 8, a wire feed wheel 9, a wire stripping elastic component 10, a control screw 11 and a motor 12, the wire stripping wheel 8 and the wire feed wheel 9 are arranged in parallel on the mounting bracket 7, the wire stripping wheel 8 is located above the wire feed wheel 9, the control screw 11 is vertically penetrated by the mounting bracket 7, the control screw 11 is connected to the wire stripping wheel 8 through the wire stripping elastic component 10, and the motor 12 is connected to the wire feed wheel 9 for driving the wire feed wheel 9 to feed the wire; and a bottom plate 13, the bottom plate 13 is arranged at the bottom of the fixed platform 1 and the mounting bracket 7, and is used to connect the wire cutting mechanism and the wire stripping mechanism.

[0033] like Figure 2 As shown, the two ends of the wire stripping wheel 8 and the wire feeding wheel 9 respectively have support rods, and the support rods at both ends of the wire stripping wheel 8 and the wire feeding wheel 9 are passed through the vertical surface of the mounting bracket 7 through fasteners, and the parts of the wire stripping wheel 8 and the wire feeding wheel 9 that contact the wire are matched, and the convex part of the wire stripping wheel 8 and the concave part of the wire feeding wheel 9 are correspondingly arranged. When the motor 12 is started, the wire stripping wheel 8 and the wire feeding wheel 9 are driven to move relative to each other, so that the wire can smoothly pass through the narrow channel between the convex part of the wire stripping wheel 8 and the concave part of the wire feeding wheel 9.

[0034] like Figure 3 As shown, the wire cutting elastic component 4 is inserted between the upper surface of the fixed platform 1 and the top plate 5 via fasteners. The two ends of the pressing handle 6 are fixed to the upper surface of the top plate 5 via fasteners. The upper and lower wire cutting blades 2 and 3 are fixed respectively between the lower surface of the top plate 5 and the upper surface of the fixed platform 1 via fasteners. The cutting edges of the upper and lower wire cutting blades 3 face each other, forming an arc-shaped cutting edge for accommodating the wire. To accommodate a wider range of wire sizes, the wire cutting blades can be replaced with blades of different inner hole sizes to improve the practicality of the device.

[0035] In some embodiments, the automatic wire stripping device further includes a spring liner sleeve disposed around the outer periphery of the wire stripping elastic component 10. The spring liner acts as a protective layer over the spring, effectively reducing direct contact between the spring and other components or media, thereby reducing the risk of wear and damage to the spring, thereby helping to extend the service life of the spring and improving its stability and reliability.

[0036] In some embodiments, the upper and lower cutting blades 2 and 3 are arc-shaped blades. These blades provide a gentler cutting surface, more effectively reducing physical damage to the wire than straight or sharp blades, particularly when cutting softer wires. These blades provide a more uniform cutting force during the cutting process, resulting in a smoother cut surface and reducing burrs and unevenness, thereby improving the overall cutting quality of the wire.

[0037] In some embodiments, the wire cutting elastic component 4 and the wire stripping elastic component 10 are flexible elastic components. When squeezed by the pressing handle 6, the flexible elastic components maintain a high degree of stability, reducing damage to the wire caused by sudden compression. Specifically, the wire cutting elastic component 4 and the wire stripping elastic component 10 are springs. The wire cutting elastic component 4 rebounds after cutting, without affecting subsequent stripping.

[0038] In some embodiments, the height of the wire placement position in the lower wire cutting blade 3 and the wire passing position of the wire feeding wheel 9 are the same. Figure 2 and 3As shown, the circular area formed by the upper wire cutting blade 2 and the lower wire cutting blade 3 is the position where the wire is placed, and the narrow channel between the convex part of the stripping wheel 8 and the concave part of the feed wheel 9 is the position where the wire passes. The heights of the two should be the same to ensure the smooth passage of the wire. By setting the heights of the wire passing positions of the lower wire cutting blade 3 and the feed wheel 9 to be consistent, it can be ensured that the wire maintains a stable position during the cutting process, thereby avoiding inaccurate cutting due to position offset. The proper height coordination between the feed wheel 9 and the wire cutting blade can ensure the smooth movement of the wire, reduce jamming or stagnation, and improve production efficiency. When the height is properly coordinated, the wire cutting blade can complete the cutting action quickly and accurately, shorten the cutting cycle, and further increase the production speed.

[0039] In some embodiments, the upper and lower cutting blades 2 and 3 comprise multi-segment blade sets. These blade sets can be arranged in parallel, allowing multiple blades to operate simultaneously during the cutting process. This significantly increases cutting speed compared to single-blade cutting, thereby improving overall production efficiency. Due to the presence of the multi-segment blade set, when a blade segment wears out or needs replacement, the other blades can continue to operate, reducing downtime due to blade changes and improving device utilization.

[0040] In some embodiments, the automatic wire stripping device is further equipped with a pressure sensor, located on the lower wire cutting blade 3. This pressure sensor monitors changes in pressure between the blade and the wire in real time during the cutting process. This precise pressure monitoring ensures uniform and stable cutting force, avoiding uneven or incomplete cuts caused by uneven force. If abnormal resistance or excessive pressure is encountered during the cutting process, the pressure sensor quickly senses it and sends a signal, triggering the device's overload protection mechanism, thereby preventing equipment damage or personal injury caused by excessive cutting force.

[0041] In some embodiments, the automatic wire stripping device further includes an inlet guide assembly and an outlet guide assembly, which are disposed at both ends of the inlet wheel 9 along the wire feed direction. The inlet guide assembly and the outlet guide assembly ensure that the wire maintains a stable path during the stripping process, reducing inaccurate stripping caused by wire shaking or deviation. The stable guiding effect helps improve the accuracy and consistency of wire stripping.

[0042] In some embodiments, the automatic wire stripping device further includes a storage mechanism, which is disposed below the wire feed wheel 9 and is used to store fallen wire insulation. Scattered insulation may interfere with the normal operation process, resulting in interruptions. The use of a storage mechanism helps maintain the continuity of the operation process and avoid unnecessary interruptions and delays. Insulation materials may also cause certain environmental pollution, especially when they are discarded carelessly. The storage mechanism can ensure that the insulation is properly handled and reduce environmental pollution. Specifically, the storage mechanism is a storage box.

[0043] In some embodiments, a track is provided at the bottom of the base plate 13. This track design allows the base plate 13 to slide smoothly along a fixed path, reducing shaking and instability and improving stability. To lock the track, a track clamp can be used to press the track against the base plate. Bolts secure the clamp to the base plate, increasing friction between the track and the base plate to prevent the track from sliding.

[0044] The motor 12 is mounted on the base plate 13 and connected to the wire feed wheel 9 for automatic wire feeding. The control screw 11 is connected to the stripping wheel 8 and controls the height between the stripping wheel 8 and the wire feed wheel 9. The lower wire cutting blade 3 is mounted on the fixed platform 1, and the upper wire cutting blade 2 is mounted below the pressing handle 6. By pressing the pressing handle 6 to make the two wire cutting blades contact, the wire cutting is completed.

[0045] A specific application of the present utility model is: select a blade with a suitable inner diameter, place the wire between the upper wire cutting blade 2 and the lower wire cutting blade 3, use appropriate force to complete radial cutting, start the motor 12, drive the stripping wheel 8 to move and drive the wire to move, and control the height between the stripping wheel 8 and the feed wheel 9 by controlling the screw 11 to complete the stripping of the axial insulation layer.

[0046] The utility model has at least the following advantages:

[0047] (1) The part used to cut the insulation layer radially. The wire cutting blade can be replaced with blades of different inner hole sizes according to the wire diameter. Two springs are installed under the pressing handle to rebound after cutting, which will not affect the subsequent stripping action.

[0048] (2) The part used for axially stripping the insulation layer, the motor drives the wire feed wheel to automatically feed the wire. When stripping wires of different diameters, the height of the wire cutting wheel can be adjusted by turning the screw to achieve diversified wire cutting.
