[0002] In the implementation of solutions for disassembling the ends of braided wires, existing technologies face challenges in cutting the outer sheath due to its material, which is typically a thermoplastic polymer such as PVC or PE. This material has a certain degree of hardness, making cutting difficult and prone to problems such as incomplete cutting or the outer sheath sticking to the internal fiber core. This leads to difficulties in subsequent peeling and affects the cutting of the outer sheath at the end of the wire. Therefore, existing technologies urgently need improvement and refinement.

[0003] Therefore, finding a suitable device and method for cutting the outer sheath of braided wires is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Both the upper and lower shearing blades are equipped with heating tubes to heat at least the upper and lower arc-shaped cutting edges.

[0007] Furthermore, the shearing temperature of the upper and lower arc-shaped cutting edges is ≥300℃.

[0008] Furthermore, the outer skin pull-out assembly includes an upper clamping block, a lower clamping block, a longitudinal cylinder, a transverse slide rail, a main shearing bracket, and a transverse cylinder; The longitudinal cylinder controls the relative or opposite movement of the upper and lower clamping blocks through the longitudinal telescopic rod. The relative movement of the upper and lower clamping blocks clamps the outer sheath of the braided wire. The transverse cylinder controls the upper clamping block, lower clamping block, and longitudinal cylinder as a whole to move along the transverse slide rail away from the braided wire in order to pull off the clamped outer sheath.

[0009] Furthermore, the main shearing bracket of the outer skin pull-out assembly is also provided with an axial rotation mechanism, which can control the upper clamping block, the lower clamping block, and the longitudinal cylinder to rotate as a whole in the lateral direction to further complete the circumferential cutting of the upper and lower shearing blades.

[0010] According to an embodiment of the present invention, using the braided wire sheath cutting device of the first solution provided by the present invention, a second solution is provided as follows: A method for cutting the outer sheath of a braided electrical wire, comprising the following steps: The braided wire is moved to the outer sheath cutting station using the wire harness fixing assembly; Once the heating process is complete, the cutting head assembly will use heat melting to cut the wire ends at the outer sheath cutting station.

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 In existing technologies, when cutting the outer sheath of braided wires, the outer sheath material is usually a thermoplastic polymer, such as PVC or PE, which has a certain degree of hardness, making it difficult to cut. In particular, problems such as incomplete cutting or the outer sheath sticking to the internal fiber core are prone to occur, leading to difficulties in subsequent peeling and affecting the cutting of the outer sheath of the wire end. Therefore, existing technologies urgently need to be improved and perfected.

[0020] See Figure 1 and Figure 2 As shown, this embodiment provides a braided wire sheath cutting device, applied to a fully automatic braided wire dismantling system, including a wire harness fixing assembly, a cutting head assembly, and an sheath pulling assembly; the wire harness fixing assembly horizontally fixes one end of a braided wire and positions the wire end at the processing position of the cutting head assembly; the cutting head assembly heat-melts and cuts off the outer sheath of the braided wire at the processing position; the sheath pulling assembly pulls off the heat-melted cut outer sheath in a direction away from the braided wire.

[0021] It should be noted that the wire harness fixing assembly includes two pneumatic clamping blocks, used to fix the two ends of the braided wire respectively; the upper and lower shearing blades of the cutter head assembly can be made of stainless steel, with the blade edge machined into a semi-circular arc shape adapted to the wire; the outer sheath pulling assembly includes an upper clamping block 13, a lower clamping block 11, a longitudinal cylinder 15, a transverse slide rail, and an axial rotation motor. The longitudinal cylinder 15 drives the clamping block to close, clamping the cut outer sheath, and the transverse cylinder 17 pushes the clamping block to move along the slide rail, pulling the outer sheath from the wire core. Through the cooperation of the longitudinal cylinder 15 and the cylinder extension rod 14, the closing and cutting of the upper and lower shearing blades are realized. The wire harness fixing assembly, through the clamping structure and stepper drive, ensures that the wire is accurately fed to the processing position, improving cutting accuracy and automation continuity. The outer sheath pulling assembly, through the transverse pulling of the clamping block and axial rotation circumferential cutting, efficiently peels off and cuts the outer sheath, with high efficiency and little residue, improving peeling efficiency.

[0022] Specifically, the wire harness fixing assembly includes wire clamping assemblies. Each wire clamping assembly horizontally fixes one end of a braided wire, and the corresponding other wire clamping assembly horizontally fixes the other end of the braided wire. The two corresponding wire clamping assemblies are driven to move step by step by a driver.

[0023] It should be noted that, on the one hand, by fixing both ends of the braided wire separately with the wire clamping assembly, the axial movement problem caused by traditional single-end fixing is solved, ensuring that the wire does not shift during processing. This, combined with the stepper movement driven by the actuator, precisely delivers the braided wire to the processing position, facilitating subsequent cutting and stripping. On the other hand, the double-end fixing structure and stepper drive form a continuous automated conveying system, achieving automatic feeding, positioning, and conveying of the braided wire without manual intervention. This significantly improves the continuity of equipment operation and increases processing efficiency.

[0024] Specifically, the blade assembly includes an upper shearing blade 12 and a lower shearing blade 10 adapted to each other. The upper shearing blade 12 has an upper arc-shaped cutting edge adapted to the shape of the braided wire on its blade edge, and the lower shearing blade 10 has a lower arc-shaped cutting edge adapted to the shape of the braided wire on its blade edge. Both the upper shearing blade 12 and the lower shearing blade are provided with heating tubes to heat at least the upper arc-shaped cutting edge and the lower arc-shaped cutting edge.

[0025] It should be noted that the upper shearing blade 12 and the lower shearing blade 10 are adapted to the shape of the braided wire, avoiding the compression damage to the wire core caused by the traditional straight blade.

[0026] Specifically, the shearing temperature of the upper and lower arc-shaped cutting edges is ≥300℃.

[0027] It should be noted that the heating element heats the curved blade to ≥300℃, enabling rapid cutting and preventing outer skin adhesion and rough edges, resulting in a cleaner cut. The high-temperature heat-melting shearing process eliminates debris splashing, requiring no secondary processing and improving shearing efficiency.

[0028] Example 2 Based on Example 1, see [link / reference] Figure 1 and Figure 2 As shown, this embodiment provides further technical solutions.

[0029] Specifically, the outer sheath pull-out assembly includes an upper clamping block 13, a lower clamping block 11, a longitudinal cylinder 15, a transverse slide rail 18, a main shearing bracket 16, and a transverse cylinder 17. The longitudinal cylinder 15 controls the relative or opposite movement of the upper clamping block 13 and the lower clamping block 11 through a longitudinal telescopic rod, and the relatively moving upper clamping block 13 and the lower clamping block 11 clamp the outer sheath of the braided wire. The transverse cylinder 17 controls the upper clamping block 13, the lower clamping block 11, and the longitudinal cylinder 15 to move as a whole along the transverse slide rail 18 away from the braided wire in order to pull off the clamped outer sheath.

[0030] It should be noted that both the upper clamping block 13 and the lower clamping block 11 can be made of aluminum alloy. Anti-slip pads can be attached to the clamping surfaces. The anti-slip pads can be made of silicone rubber and the surface is processed into an arc-shaped groove that is compatible with braided wires. The upper clamping block 13 and the lower clamping block 11 have built-in pressure sensors to provide real-time feedback on the clamping force.

[0031] It is worth noting that after the cutter head assembly cuts the outer sheath, the longitudinal cylinder 15 drives the upper clamping block 13 to move and close with the lower clamping block 11, clamping the cut outer sheath; the transverse telescopic rod 19 pushes the upper clamping block 13 and the lower clamping block 11 along the slide rail away from the wire through the transverse cylinder 17, thereby pulling the outer sheath out of the core of the braided wire and peeling it off.

[0032] Specifically, the main shearing bracket 16 of the outer skin pull-out assembly is also provided with an axial rotation mechanism. The axial rotation mechanism can control the upper clamping block 13, the lower clamping block 11, and the longitudinal cylinder 15 to rotate as a whole in the lateral direction to further complete the circumferential cutting of the upper shearing blade 12 and the lower shearing blade 10.

[0033] It should be noted that a ring cut has been added to the clamping and pulling method in the previous embodiment. After the cutter head assembly completes the axial shearing of the outer sheath, the longitudinal cylinder 15 drives the upper clamping block 13 and the lower clamping block 11 to clamp and cut the outer sheath; the transverse cylinder 17 pushes the upper clamping block 13 and the lower clamping block 11 to move along the slide rail, pulling the outer sheath off the core of the braided wire; the servo motor drives the rotating mechanism to rotate the upper clamping block 13, the lower clamping block 11, the longitudinal cylinder 15, and the transverse cylinder 17 as a whole 360° along the transverse axis. While rotating, the transverse cylinder 17 maintains a slight tension, so that the upper clamping block 13 and the lower clamping block 11 drive the outer sheath to rotate around the core of the braided wire, which, together with the heated arc-shaped blade of the cutter head assembly, completes the annular shearing; after the annular cut is completed, the transverse cylinder 17 continues to push the upper clamping block 13 and the lower clamping block 11 to move to the maximum stroke, completely pulling off the annularly sheared outer sheath; finally, the upper clamping block 13 and the lower clamping block 11 are released, and the rotating mechanism returns to the initial angle.

[0034] Example 3 According to the implementation scheme of this embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, applying the braided wire sheath cutting device in the first solution provided by this invention, a second solution is provided as follows: A method for cutting the outer sheath of a braided electrical wire, comprising the following steps: S1: Move the braided wire to the outer sheath cutting station using the wire harness fixing assembly; S2: Start the heated cutter head assembly to cut the wire ends on the outer sheath cutting station by heat melting the outer sheath; S3: Activate the outer sheath pull-out assembly to pull and peel off the heat-melted sheath away from the braided wire.

[0035] It should be noted that the servo slide of the wire harness fixing assembly moves the braided wire to the outer sheath cutting station. The clamping block clamps the wire, the cutter head assembly starts, the heated arc-shaped blade closes, and the outer sheath is thermally melted and cut off. The longitudinal cylinder 15 of the outer sheath pulling assembly drives the upper clamping block 13 and the lower clamping block 11 to clamp the cut outer sheath, and the transverse cylinder 17 pushes the clamping block along the slide rail away from the braided wire, completely pulling off the thermally melted outer sheath. After the pulling is completed, the clamping block is released, the transverse cylinder 17 returns to its original position, and the wire harness fixing assembly pushes the wire forward, ready for the next cut. The wire harness fixing assembly, through the clamping structure and stepper drive, ensures that the wire is accurately fed to the processing position, improving cutting accuracy and automation continuity. The outer sheath pulling assembly, through the transverse pulling of the clamping block and axial rotation circumferential cutting, efficiently peels off the outer sheath, with high efficiency and little residue, thus improving peeling efficiency.

[0036] Specifically, the steps for heat-melting and shearing the outer skin include: R1: Drive the upper shearing blade 12 and / or the lower shearing blade 10 to move so that the upper arc-shaped blade of the upper shearing blade 12 and the lower arc-shaped blade of the lower shearing blade 10 move relative to each other to cut the outer sheath of the braided wire. It should be noted that the wire harness fixing assembly delivers the wire to the cutting station, ensuring that the wire end extends 20-25mm beyond the cutter head; the servo motor drives the upper cutting blade 12 to move downward, and the upper arc-shaped blade and the lower arc-shaped blade close together to heat-melt and cut off the outer sheath. The sheath softens at high temperature and forms a molten layer to prevent adhesion; after cutting, the upper cutting blade 12 returns to its original position, and the cut forms a flat and burr-free annular cross section.

[0037] The steps involved in peeling off the outer skin include: W1: Drive the upper clamping block 13 and / or the lower clamping block 11 to move so that the upper clamping block 13 and the lower clamping block 11 move relative to each other to clamp the cut outer skin; It should be noted that after the longitudinal cylinder 15 drives the upper clamping block 13 to move down and close with the lower clamping block 11, the pressure sensor detects in real time to ensure that the outer sheath is clamped and the core of the braided wire is not damaged; the annular grooves of the upper clamping block 13 and the lower clamping block 11 fit with the outer sheath of the wire, and the anti-slip pad increases the friction to prevent slippage.

[0038] W2: Drive the upper clamping block 13 and lower clamping block 11, which clamp the outer sheath, to move away from the braided wire to pull off the stripped and cut outer sheath.

[0039] It should be noted that the transverse cylinder 17 pushes the upper clamping block 13 and the lower clamping block 11, and the longitudinal cylinder 15 to move along the slide rail away from the wire. During the pull-out process, the outer sheath cut by heat fusion separates from the core of the braided wire under the action of tension. After the pull-out is completed, the pressure sensor feeds back the pressure, the clamping block is released, and the transverse cylinder 17 is reset.

[0040] It is worth noting that, Specifically, the steps of heat-melting and shearing the outer skin also include: R2: Drive the upper shearing blade 12 and the lower shearing blade 10 to rotate along the axis of the braided wire to further complete the circumferential cutting.

[0041] It should be noted that by driving the upper shearing blade 12 and the lower shearing blade 10 to rotate along the axis of the braided wire, a ring cut is achieved on the heat-melted softened outer sheath. The rotating ring cut makes the blade edge more evenly stressed, avoids the local stress concentration of traditional shearing, and extends the service life of the blade head.

[0042] Specifically, the outer skin detachment and peeling step also includes: W31: Pressure sensors are provided on the clamping surfaces of the upper clamping block 13 and / or the lower clamping block 11 to acquire pressure parameters; W32: Monitors the pressure parameter and triggers a release signal when the pressure parameter is 0; W33: Reset the upper clamping block 13 and / or the lower clamping block 11 according to the release signal to release the pulled-off outer skin.

[0043] It should be noted that the pressure monitoring and reset process solves the problems of outer skin residue or equipment jamming in the existing technology, and the pull-out status is fed back in real time through pressure parameters.
