Description

Technical Field

[0002] Linear motors require electrical connection to a power source via a power cord. During production, this connection is typically achieved through soldering.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a power cord stripping device, including a support base 11, a circumferential cutting assembly, and a longitudinal cutter 31.

[0031] The support base 11 is used to support the wire to be stripped and provides a working reference for the other components. The support base 11 can be fixed to a workbench to prevent it from moving freely. A limiting structure, such as a limiting groove 111, can be provided on the support base 11. During operation, the wire to be stripped is placed in the limiting structure, which prevents the wire from moving freely relative to the support base 11.

[0032] In this embodiment of the invention, the stripping of the outer sheath of the wire to be stripped is mainly divided into circumferential cutting and longitudinal cutting. The circumferential cutting action is realized by the circumferential cutting component, and the longitudinal cutting action is realized by the longitudinal cutter 31.

[0033] Among them, circumferential cutting involves creating a groove along the circumference of the outer sheath to form an annular groove; longitudinal cutting involves creating a groove along the axial direction of the wire to be stripped. After performing circumferential and longitudinal cutting on the wire to be stripped in sequence, the outer sheath corresponding to the required part of the wire can be easily stripped off, and then subsequent welding processing can be carried out.

[0034] The circumferential cutting assembly is disposed on one side of the support base 11. Preferably, the circumferential cutting assembly is also fixed to the worktable to ensure that its positional relationship with the support base 11 is relatively fixed, so as to facilitate rapid positioning operations. In this embodiment of the invention, the circumferential cutting assembly includes a turntable 21 and two circumferential cutters 22.

[0035] The turntable 21 has a wire-passing hole 211 for threading the wire to be stripped. Considering the need to strip wires of different diameters, the diameter of the wire-passing hole 211 can be set relatively large to achieve compatibility. For example, if a batch of wires to be stripped has a diameter of 5 to 12 mm, the diameter of the wire-passing hole 211 can be set to 13 mm.

[0036] The turntable 21 is configured to rotate around the axis of the wire through hole 211 for circumferential cutting. For example, a frame can be set on the worktable, with the frame positioned on one side of the support base 11, and the turntable 21 is rotatably connected to the frame to achieve rotation around the axis of the wire through hole 211.

[0037] The rotation drive of the turntable 21 can be manual or automatic. For example, a rotating handle can be provided for the turntable 21 to be rotated manually by the operator; alternatively, a corresponding rotation driver 23 can be provided for the turntable 21 to achieve rotation drive, such as a motor or a rotary cylinder.

[0038] In this embodiment of the invention, two ring cutters 22 are respectively disposed on both radial sides of the through hole 211. Each ring cutter 22 includes a fixed end and a free end. The fixed end of the ring cutter 22 is rotatably connected to the turntable 21, so that the ring cutter 22 can rotate relative to the turntable 21 to adjust the relative position of its blade with respect to the axis of the through hole 211.

[0039] In this way, on the one hand, it facilitates wire threading, allowing the wire to be stripped to move relative to the wire through-hole 211 of the turntable 21 when the two ring cutters 22 are relatively far apart and not affected by other components. On the other hand, it also allows for compatibility with wires of different diameters by adjusting the relative position of the blades of the ring cutters 22.

[0040] In this embodiment of the invention, the fixed ends of the two ring cutters 22 are connected by a drive mechanism, ensuring that the two ring cutters 22 rotate synchronously when rotating relative to the turntable 21. As the ring cutters 22 rotate relative to the turntable 21, their free ends can move closer or further apart. This effectively avoids the problem of inconsistent cutting depths between the two ring cutters 22 and also saves adjustment time, eliminating the need for individual adjustment of each ring cutter 22.

[0041] The main body of the ring cutter 22 can be used to abut the wire to be stripped, thereby allowing the blade of the ring cutter 22 to cut into the outer sheath of the wire to be stripped. The blade of the ring cutter 22 can be configured to be adjustable, thereby adjusting the extension length of the blade relative to the main body, further enhancing the compatibility and adaptability of the device. Alternatively, the blade of the ring cutter 22 can be configured to be detachable, allowing it to be removed and replaced with a new one after a certain period of use.

[0042] During circumferential cutting, the circumferential cutter 22 is controlled to rotate relative to the turntable 21, and the free ends of the two circumferential cutters 22 are brought closer to each other until the main body of the circumferential cutter 22 comes into contact with the wire to be stripped through the wire through hole 211, so that the blade of the circumferential cutter 22 cuts into the outer sheath of the wire to be stripped.

[0043] Subsequently, the control turntable 21 rotates around the axis of the wire through hole 211, preferably by 180 degrees, so that the wire to be stripped can be longitudinally cut by the blade of the longitudinal cutter 31. Preferably, when performing ring cutting, the wire to be stripped is pressed firmly by the longitudinal cutter 31 beforehand to prevent the wire to be stripped from rotating with the turntable 21.

[0044] In this embodiment of the invention, the longitudinal cutter 31 is disposed above the support base 11. The longitudinal cutter 31 is configured to move relatively close to or relatively far from the support base 11.

[0045] Preferably, the slitting tool 31 moves in a direction parallel to the vertical. The movement of the slitting tool 31 can be manual or automatic. For example, a lifting guide rail can be provided for the slitting tool 31 to allow for manual lifting by an operator. Alternatively, a linear actuator, such as an electric cylinder or a pneumatic cylinder, can be used to drive the lifting of the slitting tool 31.

[0046] When the longitudinal cutter 31 is relatively far away from the support base 11, the longitudinal cutter 31 is separated from the wire to be stripped, and the wire to be stripped can be loaded and unloaded at this time.

[0047] With the longitudinal cutter 31 relatively close to the support base 11, the longitudinal cutter 31 abuts against and presses the wire to be stripped, and at the same time, the blade of the longitudinal cutter 31 also cuts into the outer sheath of the wire to be stripped. The pressing of the wire to be stripped by the longitudinal cutter 31 is mainly to prevent the wire to be stripped from rotating synchronously with the turntable 21 and the ring cutter 22, and the longitudinal cutter 31 does not restrict the axial movement of the wire to be stripped.

[0048] For example, the wire to be stripped is first pressed onto the support base 11 by the longitudinal cutter 31, and then the wire to be stripped is circumcised by the circumcised assembly. After the circumcised is completed, the circumcised cutter 22 is controlled to rotate relative to the turntable 21, the free ends of the two circumcised cutters 22 move away from each other, the main body of the circumcised cutter 22 releases the wire to be stripped, and the blade of the circumcised cutter 22 separates from the wire to be stripped.

[0049] At this time, the longitudinal cutter 31 remains in contact with the wire to be stripped, and the blade of the longitudinal cutter 31 remains within the outer sheath of the wire. Therefore, by simply controlling the movement of the wire to be stripped relative to the support base 11, the blade of the longitudinal cutter 31 can longitudinally cut the wire to be stripped. That is, when the longitudinal cutter 31 is relatively close to the support base 11 and in contact with the wire to be stripped, and the free ends of the two ring cutters 22 are relatively far apart and released from the wire to be stripped, the blade of the longitudinal cutter 31 longitudinally cuts the wire to be stripped.

[0050] The wire to be stripped can be moved manually by pulling it, or an additional drive can be used to perform this action. The blade of the longitudinal cutter 31 can be made adjustable, thereby adjusting the extension size of the blade relative to the main body, further enhancing the compatibility and adaptability of the device. Alternatively, the blade of the longitudinal cutter 31 can be made detachable, allowing it to be removed and replaced with a new one after a certain period of use.

[0051] When stripping wires using the power cord stripping device, firstly, the longitudinal cutter 31 is moved relatively away from the support base 11, while simultaneously the two ring cutters 22 are rotated relative to the turntable 21, with their free ends moving relatively away from each other. This allows the wire to be stripped to be placed on the support base 11 and passed through the wire-passing hole 211 of the turntable 21, with the appropriate ring-cutting position adjusted.

[0052] Next, the longitudinal cutter 31 is moved relatively close to the support base 11, so that the longitudinal cutter 31 comes into contact with and presses against the wire to be stripped, and the blade of the longitudinal cutter 31 cuts into the outer sheath of the wire to be stripped. At the same time, the two ring cutters 22 are rotated relative to the turntable 21, and the free ends of the two ring cutters 22 come closer to each other, with the main body of the ring cutter 22 abutting against the wire to be stripped, and the blade of the ring cutter 22 cutting into the outer sheath of the wire to be stripped. Then, the turntable 21 can be rotated to perform ring cutting.

[0053] After completing the ring cutting, control the two ring cutters 22 to rotate relative to the turntable 21, so that the free ends of the two ring cutters 22 move away from each other, releasing the wire to be stripped. Pull the wire to be stripped so that it moves relative to the support base 11, and the wire to be stripped can be longitudinally cut by the blade of the longitudinal cutter 31. Finally, control the longitudinal cutter 31 to move away from the support base 11 to realize unloading and reloading.

[0054] The longitudinal groove cut by the longitudinal cutter 31 does not necessarily need to be connected with the annular groove cut by the annular cutter 22. Preferably, the ends of the longitudinal groove and the annular groove are spaced apart, so that after the wire is removed from the support 11, the remaining connection part of the sheath can be torn off manually.

[0055] On the one hand, the components themselves are small in size, and their range of motion during operation is also relatively small, thus effectively ensuring the compact size of the entire machine, allowing it to be placed on a workbench for easy wire stripping by the operator. On the other hand, the support base 11, the circumferential cutting assembly, and the longitudinal cutter 31 work together to quickly achieve circumferential and longitudinal cutting, effectively shortening the time required for wire stripping and improving stripping efficiency.

[0056] In summary, the power cord stripping device provided by this invention, through the coordinated arrangement of a support base 11, a circumferential cutting component, and a longitudinal cutter 31, performs circumferential and longitudinal cuts on the wire to be stripped, removing the outer sheath. Compared to manual stripping, this device effectively reduces the risk of injury to workers, decreases wire scrap rate, and improves work efficiency. Compared to devices in related technologies, this device is compatible with different types of power cords while also achieving a small size and high stripping efficiency.

[0057] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the power cord stripping device of the present invention, the ring cutter 22 includes a ring cutting arm 221 and a ring cutting blade 222.

[0058] The circumferential cutting arm 221 is responsible for rotatably connecting with the turntable 21, mounting the circumferential cutting blade 222, and abutting the wire to be stripped. The circumferential cutting arm 221 has a first rotating part 22111 and a second rotating part 22112, with the first rotating part 22111 located at the fixed end of the circumferential cutting arm 221. The turntable 21 has a third rotating part (not shown in the figure), which is rotatably connected to the first rotating part 22111.

[0059] In this configuration, one of the first rotating part 22111 and the third rotating part can be configured as a through hole, and the other as a rotating shaft, with a clearance fit between them to achieve a rotatable connection. Alternatively, both rotating parts can be configured as through holes, with an additional pin to achieve a rotatable connection between them. Preferably, the rotation axis of the ring-cutting arm 221 is parallel to the rotation axis of the turntable 21.

[0060] Along the length of the circumferential cutting arm 221, the second rotating part 22112 is disposed between the fixed end and the free end of the circumferential cutting arm 221. Preferably, the second rotating part 22112 is positioned relatively close to the free end. The circumferential cutting blade 222 has a fourth rotating part 2221, which is rotatably connected to the second rotating part 22112.

[0061] In this configuration, one of the second rotating part 22112 and the fourth rotating part 2221 can be configured as a through hole, and the other as a rotating shaft, with a clearance fit between them to achieve a rotatable connection. Alternatively, both rotating parts can be configured as through holes, with an additional pin to achieve a rotatable connection between them. Preferably, the rotation axis of the circumferential cutting blade 222 is parallel to the rotation axis of the turntable 21.

[0062] Different specifications of wires to be stripped may have different diameters and varying outer sheath thicknesses. To address this issue, before circumcision, the installation angle of the circumcision blade 222 relative to the circumcision arm 221 can be adjusted, thereby adjusting the size of the blade extending from the circumcision arm 221.

[0063] This allows the ring cutter 22 to easily accommodate outer sheaths of various thicknesses, effectively improving the device's adaptability. The rotary adjustment structure makes adjustment quick and convenient, effectively reducing the time spent on debugging. In addition, the precise blade extension dimension effectively avoids damage to the shielding layer between the outer sheath and the internal copper wire, reducing the scrap rate.

[0064] Furthermore, refer to Figure 3 and Figure 4 As shown, in some embodiments of the power cord stripping device of the present invention, the circumferential cutting arm 221 further has a first adjustment hole 22121.

[0065] Preferably, the opening of the first adjustment hole 22121 is correspondingly disposed to the side surface of the circumferential cutting blade 222. For example, a groove can be made on the circumferential cutting arm 221, the circumferential cutting blade 222 can be disposed in the groove, and the first adjustment hole 22121 can be provided on the side wall of the groove.

[0066] A first adjusting member 223 is provided in the first adjusting hole 22121. The first adjusting member 223 is movable relative to the first adjusting hole 22121 to press against or loosen the circumferential cutting blade 222.

[0067] For example, the first adjusting hole 22121 can be configured as a threaded hole, and the first adjusting member 223 can be configured as a bolt, with the two connected by threads. By loosening the bolt, the tail of the bolt can be separated from the circumferential cutting blade 222, releasing the circumferential cutting blade 222 so that it can be rotated to adjust its blade extension size. By tightening the bolt, the head of the bolt can be brought into contact with the circumferential cutting blade 222, pressing the circumferential cutting blade 222 and restricting its rotation so that subsequent circumferential cutting operations can be performed.

[0068] In this way, the clamping and releasing of the circumferential cutting blade 222 can be easily achieved, ensuring high overall compatibility while effectively reducing the time spent on debugging.

[0069] Reference Figure 3 and Figure 4 As shown, in some embodiments, the circumferential cutting arm 221 also has a second adjustment hole 22113. The opening of the second adjustment hole 22113 is correspondingly disposed on the back side of the circumferential cutting blade 222. For example, the second adjustment hole 22113 can be provided on the bottom surface of the groove where the circumferential cutting blade 222 is located.

[0070] A second adjusting member 224 is provided inside the second adjusting hole 22113, and the second adjusting member 224 abuts against the circumferential cutting blade 222. The second adjusting member 224 is movable relative to the second adjusting hole 22113 to drive the circumferential cutting blade 222 to rotate relative to the circumferential cutting arm 221. Preferably, the direction of movement of the second adjusting member 224 is perpendicular to the rotation axis of the turntable 21.

[0071] For example, the second adjusting hole 22113 can be configured as a threaded hole, and the second adjusting member 224 can be configured as a bolt, with the two connected by threads. When the first adjusting member 223 is loosened from the circumferential cutting blade 222, the bolt can be loosened to separate the tail of the bolt from the circumferential cutting blade 222, so that the circumferential cutting blade 222 can be rotated, thereby reducing its blade extension size. By tightening the bolt, the bolt head can be brought into contact with the circumferential cutting blade 222, so that the circumferential cutting blade 222 can be rotated, thereby increasing its blade extension size.

[0072] In this way, the blade extension size of the circumferential cutting blade 222 can be easily adjusted, ensuring high overall compatibility while effectively reducing the time spent on debugging.

[0073] Preferably, a block structure can be provided on the circumferential cutting arm 221, and the second adjustment hole 22113 can be provided on the block structure. This allows for the provision of installation space for the second adjustment member 224 while providing rotational limit for the circumferential cutting blade 222 through the block structure.

[0074] For example, a first limiting surface 22116 and a second limiting surface 22117 can be provided on the block structure. Both the first limiting surface 22116 and the second limiting surface 22117 are perpendicular to the disk surface of the turntable 21. The first limiting surface 22116 is perpendicular to the moving direction of the second adjusting member 224. The second limiting surface 22117 has an included angle with the first limiting surface 22116. The second limiting surface 22117 is parallel to the axis of rotation of the circumferential cutting blade 222.

[0075] In this way, the minimum blade extension size of the circumferential cutting blade 222 can be limited by the first limiting surface 22116, and the maximum blade extension size of the circumferential cutting blade 222 can be limited by the second limiting surface 22117, so as to prevent the circumferential cutting blade 222 from failing to perform effective circumferential cutting, and to prevent the circumferential cutting blade 222 from rotating too far and damaging the intermediate shielding layer.

[0076] Furthermore, refer to Figure 4 As shown, in some embodiments of the power cord stripping device of the present invention, the ring-cutting arm 221 includes an arm body 2211 and an adjusting pressure block 2212.

[0077] The arm body 2211 is responsible for rotating and connecting with the turntable 21, installing the ring cutting blade 222, and abutting the stripping wire. The arm body 2211 has a first disassembly part 22114, a first rotating part 22111, a second rotating part 22112, and a second adjustment hole 22113.

[0078] The adjusting block 2212 is used to cooperate with the arm body 2211 to install and replace the ring cutting blade 222. The adjusting block 2212 has a second disassembly part 22122 and a second adjusting hole 22113. The second disassembly part 22122 is detachably connected to the first disassembly part 22114.

[0079] For example, the two disassembly parts can be configured as a snap-fit ​​disassembly structure. Preferably, the second disassembly part 22122 is configured as a through hole, the first disassembly part 22114 is configured as a threaded hole, and a bolt is additionally provided in the through hole, the bolt being threadedly connected to the threaded hole, thereby realizing a detachable connection between the adjusting block 2212 and the arm body 2211.

[0080] The circumferential cutting blade 222 is disposed between the adjusting pressure block 2212 and the arm body 2211. One side of the circumferential cutting blade 222 abuts against the arm body 2211, and the other side abuts against the second adjusting member 224 on the adjusting pressure block 2212, thereby being limited by both. Furthermore, the fourth rotating part 2221 is detachably connected to the second rotating part 22112. Preferably, the rotatable and detachable connection is achieved by bolts.

[0081] Thus, after a certain period of use, the bolts in the adjusting block 2212 and the fourth rotating part 2221 can be removed to replace the circumferential cutting blade 222. This ensures that the circumferential cutting blade 222 of the device remains sharp, enabling smooth circumferential cutting operations and improving work efficiency. In addition, replacement is very convenient, effectively reducing the time spent on debugging.

[0082] Reference Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the power cord stripping device of the present invention, the ring-cutting arm 221 has a plurality of first transmission teeth 22115, and the first rotating part 22111 and the plurality of first transmission teeth 22115 are all disposed at one end of the ring-cutting arm 221 in the length direction, that is, the fixed end of the ring-cutting arm 221.

[0083] Along the circumference of the first rotating part 22111, a plurality of first transmission teeth 22115 are evenly arranged. At least a portion of the first transmission teeth 22115 in the two annular arms 221 mesh with each other, realizing the transmission connection between the two annular arms 221. Thus, when at least one of the free ends of the two annular arms 221 is subjected to force, the two annular arms 221 will rotate synchronously, causing the two free ends to move closer or further apart.

[0084] Turntable 21 has a default state, in which the free end of the ring cutter 22 is below the fixed end. During ring cutting, the turntable 21 can be rotated 360 degrees to achieve reset; alternatively, the turntable 21 can be rotated 180 degrees clockwise and then 180 degrees counterclockwise to achieve reset.

[0085] A threading wedge 41 is provided below the circumferential cutting assembly. The threading wedge 41 is movable relative to the circumferential cutting assembly to be relatively close to or relatively far away from the circumferential cutting assembly.

[0086] The threading wedge 41 has a wedge-shaped structure with two wedge surfaces. These two wedge surfaces are arranged sequentially along the direction of the two annular cutters 22. There is a certain angle between the two wedge surfaces.

[0087] When the wire threading wedge 41 moves relative to the ring-cutting assembly and approaches the ring-cutting assembly, the wedge surface contacts the free end of the ring-cutting arm 221, causing the two ring-cutting arms 221 to rotate synchronously and the two free ends to move away from each other. At this time, the wire can be loaded and unloaded.

[0088] Preferably, the device further includes a threading linear actuator 42, the driving end of which is connected to the threading wedge 41, thereby driving the threading wedge 41 to move. Preferably, the moving direction of the threading wedge 41 is parallel to the vertical direction.

[0089] Preferably, the linear actuator 42 is configured as a lifting cylinder. For example, a switch can be provided for the lifting cylinder to drive it to move up and down.

[0090] Preferably, a rotating component 225 is provided at the other end of the circumferential cutting arm 221 along its length, and the rotating component 225 is rotatably connected to the circumferential cutting arm 221. The rotating component 225 is located at the free end of the circumferential cutting arm 221. Preferably, the rotation axis of the rotating component 225 is parallel to the rotation axis of the circumferential cutting arm 221.

[0091] In this way, the rotating component 225 can make contact with the threading wedge 41. When the threading wedge 41 is relatively close to and in contact with the rotating component 225, the threading wedge 41 will cause the two rotating components 225 to move away from each other. Compared with the method of the threading wedge 41 directly contacting the ring-cutting arm 221, the contact between the rotating component 225 and the threading wedge 41 can change sliding into rolling, reduce the friction between the two, and make it easier to make the free ends of the two ring-cutting arms 221 move away from each other.

[0092] Preferably, the circumferential cutting assembly further includes an elastic element 226, the two elastic ends of which are respectively connected to the two circumferential cutting arms 221 to drive the rotating parts 225 of the two circumferential cutting arms 221 to move closer to each other. Preferably, the elastic element 226 is a spring.

[0093] In this way, the free ends of the two circumferential cutting arms 221 can be kept relatively close by the elastic element 226, so that the circumferential cutting arms 221 can keep in contact with the wire to be stripped during the circumferential cutting process, so as to better achieve circumferential cutting and ensure circumferential cutting efficiency and quality.

[0094] When the rotating component 225 is in contact with the threading wedge 41, the two ring-cutting arms 221 are subjected to force and overcome the elastic force of the elastic element 226, causing the two free ends to move away from each other for loading and unloading. When the rotating component 225 is separated from the threading wedge 41, after the external force is lost, the elastic element 226 causes the two free ends to move closer to each other until the ring-cutting arms 221 come into contact with the wire to be stripped.

[0095] Reference Figure 2 and Figure 3 As shown, in some embodiments of the power cord stripping device of the present invention, the turntable 21 has a plurality of second transmission teeth 212, which are evenly arranged along the circumference of the wire through hole 211.

[0096] The circumferential cutting assembly also includes a rotary actuator 23, which is disposed on the radial side of the through-hole 211. Preferably, the rotary actuator 23 is a rotary cylinder. For example, a switch can be provided for the rotary cylinder to drive it to rotate in the forward and reverse directions.

[0097] The drive end of the rotary actuator 23 is equipped with a drive disk 231, which has multiple third transmission teeth 2311. These teeth are evenly arranged along the circumference of the drive disk 231. The third transmission teeth 2311 mesh with the second transmission teeth 212 for transmission.

[0098] Thus, during circumferential cutting, the drive end of the rotary actuator 23 can drive the drive disk 231 to rotate, and the third transmission gear 2311 transmits power to the second transmission gear 212, thereby driving the turntable 21 to rotate synchronously. Compared with the manual rotary drive method, the combination of the rotary actuator 23 and the turntable 21 can achieve circumferential cutting more conveniently and accurately.

[0099] Reference Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments of the power cord stripping device of the present invention, a longitudinal cutting linear driver 32 is further included. The longitudinal cutting linear driver 32 is disposed on one side of the support base 11, and the longitudinal cutter 31 is connected to the driving end of the longitudinal cutting linear driver 32.

[0100] Preferably, the longitudinal cutting linear actuator 32 is configured as a lifting cylinder to drive the longitudinal cutter 31 to switch between an avoidance position and a longitudinal cutting position. For example, a switch can be provided for the lifting cylinder to drive its lifting and lowering.

[0101] When switched to the avoidance position, the longitudinal cutter 31 separates from the wire to be stripped, allowing for loading and unloading operations. When switched to the longitudinal cutting position, the longitudinal cutter 31 comes into contact with and presses the wire to be stripped, while the blade of the longitudinal cutter 31 cuts into the outer sheath of the wire to be stripped.

[0102] Preferably, the longitudinal cutter 31 includes a longitudinal cutting pressure block 311 and a longitudinal cutting blade 312. The longitudinal cutting pressure block 311 is mounted on the drive end of the longitudinal cutting linear drive 32. The longitudinal cutting pressure block 311 has a pressing surface 3111 and a third adjustment hole 3112. The pressing surface 3111 is located at one end of the longitudinal cutting pressure block 311 near the support base 11, and the pressing surface 3111 abuts against and presses the wire to be stripped.

[0103] The third adjustment hole 3112 is provided on the pressing surface 3111. The longitudinal cutting blade 312 passes through the third adjustment hole 3112. The longitudinal cutting blade 312 is movable relative to the third adjustment hole 3112 to adjust the size of the longitudinal cutting blade 312 relative to the longitudinal cutting pressure block 311.

[0104] In this way, the longitudinal cutting position of the longitudinal cutter 31 can be kept unchanged. Only the extension size of the longitudinal cutting blade 312 needs to be adjusted to allow the longitudinal cutter 31 to be adapted to the outer sheath of different thicknesses, which effectively improves the compatibility of the device and allows the longitudinal cutting blade 312 to complete the longitudinal cutting smoothly without damaging the intermediate shielding layer.

[0105] Furthermore, refer to Figure 6 , Figure 7 and Figure 8As shown, in some embodiments of the power cord stripping device of the present invention, the longitudinal cutter 31 further includes an adjusting guide rail 313 and an adjusting seat 314. The adjusting guide rail 313 is mounted on the driving end of the longitudinal cutting linear actuator 32, and the adjusting guide rail 313 has a plurality of fourth transmission teeth 3131, which are evenly arranged along the vertical direction.

[0106] The longitudinal cutting blade 312 is mounted on the adjusting seat 314, which is slidably connected to the adjusting guide rail 313 in the vertical direction. In this way, the longitudinal cutting blade 312 can be moved relative to the third adjusting hole 3112 by the adjusting seat 314, thereby adjusting the size of the longitudinal cutting blade 312 relative to the longitudinal cutting pressure block 311.

[0107] Preferably, the adjusting seat 314 has a fourth adjusting hole 3141, and a third adjusting member 315 is disposed in the fourth adjusting hole 3141. The third adjusting member 315 is movable relative to the fourth adjusting hole 3141 to lock or unlock the adjusting seat 314. Preferably, the moving direction of the third adjusting member 315 is perpendicular to the vertical direction.

[0108] For example, the fourth adjusting hole 3141 can be configured as a threaded hole, and the third adjusting member 315 can be configured as a bolt, with the two connected by threads. In this way, the adjusting seat 314 can be locked by pressing the adjusting guide rail 313 against the bolt, or the adjusting seat 314 can be unlocked by loosening the adjusting guide rail 313. This can effectively prevent the longitudinal cutting blade 312 from moving relative to the longitudinal cutting pressure block 311 during longitudinal cutting, ensuring efficient and accurate longitudinal cutting.

[0109] Preferably, the adjusting seat 314 also has a fifth adjusting hole 3142, and an adjusting handle 316 is disposed in the fifth adjusting hole 3142. The adjusting handle 316 is rotatable relative to the fifth adjusting hole 3142, and the two are in clearance fit. The adjusting handle 316 has a plurality of fifth transmission teeth 3161, which are evenly arranged along the circumference of the adjusting handle 316, and the fifth transmission teeth 3161 mesh with the fourth transmission teeth 3131 for transmission.

[0110] Thus, when the third adjusting component 315 releases the adjusting guide rail 313 and unlocks the adjusting seat 314, the operator can rotate the adjusting handle 316 to raise or lower the adjusting seat 314 relative to the adjusting guide rail 313. Compared to directly moving the adjusting seat 314, this structure ensures more precise adjustment, improves longitudinal cutting quality, and prevents the longitudinal cutting blade 312 from damaging the intermediate shielding layer.

[0111] Preferably, the third adjustment hole 3112 of the longitudinal cutting pressure block 311 has a hole structure on its hole wall, and a fourth adjustment member 317 is provided in the hole structure. The fourth adjustment member 317 is movable relative to the hole structure to press or loosen the longitudinal cutting blade 312.

[0112] For example, the hole structure can be set as a threaded hole, and the fourth adjusting member 317 can be set as a bolt, with the two connected by threads. By loosening the bolt, the tail of the bolt can be separated from the longitudinal cutting blade 312, releasing the longitudinal cutting blade 312 so that the adjusting seat can be moved to adjust the blade extension size of the longitudinal cutting blade 312. By tightening the bolt, the head of the bolt can be brought into contact with the longitudinal cutting blade 312, pressing the longitudinal cutting blade 312 to facilitate subsequent longitudinal cutting operations.

[0113] Preferably, the slitting blade 312 and the adjusting seat 314 are detachably connected. For example, detachable parts can be provided on both the slitting blade 312 and the adjusting seat 314, achieving a detachable connection through two detachable parts. These two detachable parts can be configured as snap-fit ​​detachable structures. Preferably, a through hole is provided in the slitting blade 312, and a threaded hole is provided in the adjusting seat 314. An additional bolt is provided in the through hole, and the bolt is threadedly connected to the threaded hole, thus achieving a detachable connection between the slitting blade 312 and the adjusting seat 314.

[0114] Reference Figure 1 and Figure 9 As shown, in some embodiments of the power cord stripping device of the present invention, the support base 11 has a limiting groove 111. The limiting groove 111 has two limiting surfaces 1111, which gradually decrease in distance along the direction from the center of the wire through hole 211 towards the bottom. In this way, the wire to be stripped can be placed in the limiting groove 111, and the two limiting surfaces 1111 contact the wire to be stripped, preventing the wire to be stripped from rolling freely before being pressed by the longitudinal cutting pressure block 311.

[0115] Preferably, the circumferential cutting component is disposed on one side of the length direction of the limiting groove 111, and the hole axis of the through hole 211 is disposed vertically above the intersection line of the two limiting surfaces 1111, and the two axes are parallel.

[0116] Reference Figure 1 and Figure 9 As shown, in some embodiments, the support base 11 further includes a through coil 12, with the through coil 12 and the circumferential cutting assembly respectively disposed on both sides of the limiting groove 111 along its length. Preferably, the hole axis of the through coil 12 is disposed vertically above the intersection line of the two limiting surfaces 1111, and the two axes are parallel. The through coil 12 can be made of ceramic material.

[0117] The wire to be stripped typically has a certain length, but due to volume considerations, the length of the limiting groove 111 is limited. This results in the wire being stripped tending to bend at the end of the limiting groove 111 furthest from the circumferential cutting component after it is placed in the limiting groove 111. When the wire is pulled, the bent portion is easily damaged. Therefore, by providing the guide coil 12, hard contact between the wire and the support base 11 can be avoided, reducing the wire scrap rate. Preferably, the guide coil 12 and the support base 11 are detachably connected.

[0118] On the other hand, embodiments of the present invention also provide a power cord stripping method, applied to the power cord stripping device described in any of the above embodiments. The power cord stripping method includes steps S10, S20, S30, S40, and S50.

[0119] Step S10: Control the longitudinal cutter 31 to move relatively close to the support base 11 and abut against the wire to be stripped carried on the support base 11.

[0120] The longitudinal cutter 31 is positioned above the support base 11.

[0121] Step S20: Control the free ends of the two ring cutters 22 in the ring cutting assembly to approach each other and abut against the wire to be stripped.

[0122] The ring-cutting assembly is located on one side of the support base 11. The ring-cutting assembly also includes a turntable 21 with a wire-passing hole 211. The wire to be stripped is passed through the wire-passing hole 211. Two ring cutters 22 are respectively located on the radial sides of the wire-passing hole 211. The fixed end of the ring cutter 22 is rotatably connected to the turntable 21, and the fixed ends of the two ring cutters 22 are connected by a transmission.

[0123] In step S30, the turntable 21 is controlled to rotate around the axis of the wire through hole 211, and the wire to be stripped is circumcised by the blade of the circumcised cutter 22.

[0124] Step S40: Control the free ends of the two ring cutters 22 to move away from each other and release the wire to be stripped.

[0125] Step S50: Control the wire to be stripped to move relative to the support 11, and use the blade of the longitudinal cutter 31 to longitudinally cut the wire to be stripped.

[0126] Working principle: First, based on parameters such as the diameter of the wire to be stripped and the thickness of the outer sheath, the blade extension dimensions of the ring cutter 22 and the longitudinal cutter 31 are adjusted to ensure that the corresponding blades can just cut through the outer sheath without damaging the middle shielding layer.

[0127] Next, the linear actuator 42 is controlled to drive the threading wedge 41 to rise. The threading wedge 41 contacts the rotating component 225 on the free end of the circumferential cutting arm 221, overcoming the elastic force of the elastic element 226, so that the two circumferential cutting arms 221 open synchronously. In this way, the wire to be stripped can be placed in the limiting groove 111 of the support base 11 and passed into the wire through hole 211 of the turntable 21, and the part to be circumferentially cut can be adjusted.

[0128] After threading is completed, the longitudinal cutting linear actuator 32 is controlled to lower the longitudinal cutter 31, causing the clamping surface 3111 of the longitudinal cutting pressure block 311 to come into contact with and press the wire to be stripped, and allowing the longitudinal cutting blade 312 to cut into the outer sheath of the wire to be stripped. Then, the threading linear actuator 42 is controlled to lower the threading wedge 41, causing the arm bodies 2211 of the two ring cutters 22 to come into contact with the wire to be stripped, and allowing the ring cutting blade 222 to cut into the outer sheath of the wire to be stripped. Next, the rotary actuator 23 is controlled to rotate the turntable 21 180 degrees clockwise to perform ring cutting, and then rotate it 180 degrees counterclockwise to reset.

[0129] The wire to be stripped after circumferential cutting is pulled out from the through hole 211. As the wire moves relative to the support 11, it is longitudinally cut by the longitudinal cutting blade 312. Finally, the worker can easily peel off the outer sheath for subsequent welding operations.

[0130] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0131] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0132] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
