[0002] The metal core of a stranded wire is covered with an insulating layer. To ensure conductivity, this outer layer must be removed before the stranded wire is installed on an electrical component.

[0058] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0059] See also Figures 1 to 4 ,as well as Figure 6 The present application provides a wire cutting device suitable for stripping the insulation layer of wires of various shapes and cutting to a specific length. It is particularly suitable for removing the insulation layer of wires with inconsistent distances from the outer surface of the insulation layer to the metal wire core, such as stranded wire; it greatly improves the efficiency of manually stripping the insulation layer of the wire. The device includes a frame 1, and a feeding mechanism 2, a stripping mechanism 3, a traction feedback mechanism 4, and a cutting mechanism 5 arranged on the frame 1 in sequence along the transmission direction of the wire. It also includes a control mechanism 6, which is electrically connected to the feeding mechanism 2, the stripping mechanism 3, the traction feedback mechanism 4, and the cutting mechanism 5 respectively, so as to achieve unified control of the device by the control mechanism 6, thereby improving the degree of automation and control accuracy of the device. The control mechanism 6 includes a PLC controller and is provided with a touch screen. Through the touch screen, parameters such as the length of the insulation layer to be removed for each wire, the cutting length of each wire, the number of wires to be cut, and the control of starting and stopping the device can be set.

[0060] The bottom of frame 1 is provided with running wheel, is convenient to the movement of this device. For avoiding this device to easily produce displacement in use, running wheel adopts the running wheel with brake mechanism.

[0061] The feeding mechanism 2 includes a first drive member 21 and a spool assembly 22. The output end of the first drive member 21 is rotatably connected to the spool assembly 22. The spool assembly 22 is arranged on the downstream side of the feeding mechanism 2 facing the direction of wire transmission, and is used to transmit the wire downstream of the feeding mechanism 2. The stripping mechanism 3 includes a mold 31 and a cutting assembly 32. The mold 31 is provided with one or more wire fixing grooves 311. Each wire fixing groove 311 corresponds to a feeding mechanism 2. The groove of the wire fixing groove 311 is upward, and the wire fixing groove 311 extends along the direction of wire transmission. The shape of the wire fixing groove 311 is adapted to the wire to be cut. The cutting assembly 32 can move away from or approach the wire fixing groove 311. When the cutting assembly 32 approaches the wire fixing groove 311, the end of the cutting assembly 32 contacts the wire in the wire fixing groove 311 and can cut the insulation layer of the wire connected to the wire fixing groove 311. When the end of the cutting component 32 contacts the wire, the distance between the end of the cutting component 32 and the wire fixing groove 311 is set to a constant value, so that the consistency of the cutting effect of each wire can be guaranteed.

[0062] The first drive member 21 uses a servo motor. The wire is wound on the spool assembly 22. When the device is in operation, the wire is pulled downstream. Generally, when the wire is released from the spool 224, it may be twisted. This may cause the distance between the insulation layer of the wire and the metal core to change. For example, when the wire to be cut is a three-stranded wire, the metal core of the three-stranded wire is formed by three strands of wire. As a result, the distance from the outer surface of the outer insulation layer to the metal core is inconsistent. When stripping the insulation layer, the depth of the stripping and cutting from different locations may be different. Therefore, if the three-stranded wire is twisted, it will cause the shape to change, making it difficult to determine the cutting depth of the cutting assembly 32. The distance between the cutting assembly 32 of the stripping mechanism 3 and the wire fixing groove 311 is set. If the twisted wire passes through the cutting assembly 32 on the stripping mechanism 3 to cut the insulation layer of the wire, it may damage the metal core, thereby affecting the use effect of the wire. The present application sets the wire fixing groove 311 to match the shape of the wire so that the twisted wire cannot pass through the wire fixing groove 311. The wire fixing groove 311 plays a certain fixing role on the wire. The first driving member 21 drives the spool assembly 22 to rotate, which can correct the twisted wire and make the wire pass through the wire fixing groove 311 in the same direction. The distance between the metal wire core of the wire and the cutting assembly 32 is kept consistent, so that the cutting assembly 32 can maintain a consistent cutting depth when cutting the wire, will not damage the metal wire core of the wire, and improves the accuracy of the device in cutting the insulation layer of the wire.

[0063] The traction feedback mechanism 4 can pull the wire downstream and calculate the transmission length of the wire to feed back to the control mechanism 6, so that the control mechanism 6 can control the cutting mechanism 5 to cut the insulation layer of the wire or cut the wire. The cutting component of the cutting mechanism 5 can be scissors or annular cutters 321, etc.

[0064] When there is a certain height difference between the bobbin assembly 22 and the mold 31, in order to improve the stability of the wire transmission, a guide mechanism can also be set between the stripping mechanism 3 and the feeding mechanism 2. The guide mechanism is set corresponding to the wire fixing groove 311 of the mold 31. The guide mechanism can reduce the height difference between the bobbin assembly 22 and the wire fixing groove 311, and play a certain supporting and guiding role on the wire, so that the guide can pass through the wire fixing groove 311 of the mold 31 more smoothly.

[0065] The mold 31 is connected to the base 33 of the stripping mechanism 3 through a screw, so that when wires of different specifications need to be stripped and cut, the mold 31 with the corresponding shape of the wire fixing groove 311 can be replaced, thereby improving the applicability of the device.

[0066] like Figures 3 to 5 As shown, the spool assembly 22 includes a fixed plate 221, a rotating mounting plate 222, a spool 224, and a wire guide plate 225. The fixed plate 221 is connected to the frame 1. The first drive member 21 is connected to the side of the fixed plate 221 facing away from the wire transmission direction via a flange. The rotating mounting plate 222 is located on the side of the fixed plate 221 facing the wire transmission direction. The first drive member 21 uses a servo motor and can drive the rotating mounting plate 222 to rotate in either forward or reverse directions. A through hole 2211 is provided on the fixed plate 221, and the output end of the first driving member 21 is passed through the through hole 2211 and is rotatably connected to the rotating mounting plate 222, and the two ends of the rotating mounting plate 222 are respectively bent toward the direction of the peeling mechanism 3, forming a "concave" row with the opening facing the peeling mechanism 3, and an accommodating space 223 is formed between the two ends of the mounting plate, and the bobbin 224 is placed in the accommodating space 223, and the two ends of the bobbin 224 are respectively connected to the two ends of the rotating mounting plate 222; in this way, when the first driving member 21 drives the rotating mounting plate 222 to rotate, it can drive the bobbin 224 to rotate, so that the wire wound on the bobbin 224 also rotates, thereby correcting the torsional state of the wire.

[0067] The wire plate 225 is connected to the rotating mounting plate 222 and is arranged on the side of the rotating mounting plate 222 facing the stripping mechanism 3. The wire plate 225 is provided with a wire hole 2251 on the side facing the stripping mechanism 3. The wire drawn from the spool 224 extends through the wire hole 2251 to the wire fixing groove 311 of the mold 31. The inner diameter of the wire hole 2251 is larger than the outer diameter of the wire, which can provide a certain support for the wire and will not restrict the rotation of the wire. In one embodiment, the wire plate 225 is "concave" with its opening facing the accommodating space 223. In this way, an enclosed space is formed between the wire plate 225 and the rotating mounting plate 222, which can limit the swing amplitude of the wire during rotation and improve the stability of the wire transmission when the spool 224 rotates.

[0068] like Figure 5 As shown, the spool assembly 22 also includes a wire pressing plate 226, which is connected to the side of the rotating mounting plate 222 facing the accommodating space 223, so that the wire pressing plate 226 is placed in the accommodating space 223, and the free end of the wire pressing plate 226 extends toward the spool 224, and the free end of the wire pressing plate 226 can press the wire toward the spool 224, preventing the wire from spreading out from the spool 224 and affecting the correction effect of the wire. Further, the wire pressing plate 226 is connected to the rotating mounting plate 222 by a spring hinge, so that the wire pressing plate 226 can be rotated to different heights, and the elastic force of the spring hinge always presses on the wire of the spool 224, adapting to the limit of different winding heights of the spool 224, and keeping the wire wound on the spool 224 regular. The width of the wire pressing plate 226 along the axial direction of the bobbin 224 is not less than the axial length of the bobbin 224 , ensuring that the wire pressing plate 226 can have a regular effect on the wires on the bobbin 224 .

[0069] like Figure 2 、 Figures 6 to 8 As shown, the peeling mechanism 3 also includes a base 33, a supporting seat 34 and a second driving member 35; the base 33 is fixed to the frame 1 by a screw, the supporting seat 34 is arranged on the base 33, the cutting assembly 32 is rotatably connected to the supporting seat 34, the second driving member 35 is rotatably connected to the supporting seat 34, and the output end of the second driving member 35 is rotatably connected to the end of the cutting assembly 32 away from the mold 31, so that the second driving member 35 can drive the cutting assembly 32 to approach or move away from the wire fixing groove 311, so as to realize the cutting assembly 32 cutting the insulation layer of the wire.

[0070] like Figures 6 to 8 As shown, the supporting seat 34 protrudes upward at both ends along the transmission direction of the wire, forming a first protrusion 341 and a second protrusion 342 respectively. The first protrusion 341 and the second protrusion 342 are arranged along the transmission direction of the wire, and the first protrusion 341 is arranged at the end of the supporting seat 34 close to the mold 31; the cutting assembly 32 includes a tool 321 and a tool handle 322, the tool 321 is connected to the end of the tool handle 322 close to the mold 31, and the end of the tool handle 322 away from the tool 321 is rotatably connected to the output end of the second driving member 35, the tool handle 322 and the first protrusion 341 are rotatably connected between the tool 321 and the output end of the second driving member 35, and the second driving member 35 is rotatably connected to the second protrusion 342. Here, the lower part of the second driving member 35 is connected to the second protrusion 342, and the output end of the second driving member 35 is tilted upward toward the knife handle 322. The second driving member 35 adopts a cylinder or an electric push rod. When the output end of the second driving member 35 is extended, it drives the upper end of the knife handle 322 to move toward the transmission direction of the wire. The lower end of the knife handle 322 is connected to the tool 321. At this time, the tool 321 moves in the opposite direction, that is, it moves away from the transmission direction of the wire, which can better cut the insulation layer on the outside of the wire.

[0071] The first protrusion 341 is also provided with a threaded hole extending through the first protrusion 341 along the direction of wire transmission. The stripping mechanism 3 also includes a stopper 36, which is inserted into the threaded hole and connected to the first protrusion 341. The stopper 36 can be adjusted to extend beyond the first protrusion 341, thereby adjusting the distance between the cutter 321 and the wire retaining groove 311. This allows the stripping device to be adapted for cutting the insulation layer of wires of varying specifications. When the cutter 321 approaches the mold 31, the stopper 36 abuts the handle 322, ensuring that the cutter 321 maintains a consistent cutting depth on the wire, thereby ensuring effective wire cutting and preventing the cutter 321 from moving, changing the distance between the cutter 321 and the wire, and potentially cutting into the metal wire core.

[0072] In this embodiment, the height ratio of the first protrusion 341 and the second protrusion 342 is 2:1, and the top of the first protrusion 341 is connected to the handle 322 at a lower middle position in the length direction of the handle 322. Under this ratio, the second driving member 35 and the handle 322 can move at a suitable angle, and the second driving member 35 can easily drive the handle 322 to rotate.

[0073] In order to improve the safety of the operation of the device, a knife cover 323 is also connected to the knife handle 322. The knife cover 323 is connected to the knife 321 to block the two sides of the knife 321 along the wire transmission direction. The knife 321 moves back and forth along the wire transmission direction, and the knife 321 is placed above the wire fixing groove 311. Therefore, the knife cover 323 will not affect the operation of the knife 321.

[0074] like Figure 2 、 Figure 9 and Figure 10As shown, the traction feedback mechanism 4 includes a roller assembly 41, a third drive member 42 and a feedback assembly 43; the third drive member 42 is connected to the frame 1, and its output end is transmission-connected to the roller assembly 41, driving the roller assembly 41 to rotate, so that the roller assembly 41 can pull the wire downstream for transmission; the feedback assembly 43 includes a rotating wheel 431 and an encoder 432, the outer periphery of the rotating wheel 431 is transmission-connected to the roller assembly 41, the rotating shaft of the rotating wheel 431 is connected to the encoder 432, and the encoder 432 is electrically connected to the control mechanism 6 for calculating the transmission length of the wire. The third drive member 42 uses a servo motor. When the device described in this application is working, the third drive member 42 drives the roller assembly 41 to rotate, and the roller assembly 41 drives the wire to be transmitted downstream. The rotating wheel 431 is in transmission contact with the roller assembly 41. The encoder 432 can calculate the rotation distance of the roller assembly 41 by calculating the rotation distance of the rotating wheel 431, thereby obtaining the transmission distance of the wire. The encoder 432 feeds the above information back to the control mechanism 6. The control mechanism 6 can control the cutting mechanism 5 to cut the wire after the transmission distance of the wire reaches the set length; this process is repeated until the set task volume is completed. Through the above setting, the device can accurately control the cutting length of the wire, reduce the error of manual cutting, and improve work efficiency.

[0075] Further, such as Figure 9 and Figure 10As shown, the roller assembly 41 includes a mounting seat 411, a driving roller 412 and a driven roller 413; there are two mounting seats 411, and the two mounting seats 411 are arranged on the frame 1 at intervals; the driving roller 412 is arranged between the two mounting seats 411, and the two ends of the driving roller 412 are rotatably connected to the two mounting seats 411 respectively, the axis of the driving roller 412 is perpendicular to the transmission direction of the wire, and the output end of the third driving member 42 is transmission connected to the driving roller 412; the driven roller 413 is rotationally connected between the two mounting seats 411, and is arranged above the driving roller 412, and its axis direction is consistent with the axis direction of the driving roller 412, and a gap adapted to the outer diameter of the wire is provided between the driven roller 413 and the driving roller 412, so that the driving roller 412 and the driven roller 413 can drive the wire to be transmitted downstream; the outer periphery of the driven roller 413 is also transmission connected to the rotating wheel 431. In the above description, the wire passes through the gap between the driving roller 412 and the driven roller 413 and abuts against the driving roller 412 and the driven roller 413, respectively. The third driving member 42 drives the driving roller 412 to rotate, thereby transmitting the wire downstream and synchronously rotating the driven roller 413. The driven roller 413 drives the rotating wheel 431 to rotate, allowing the encoder 432 to calculate the transmission length of the wire. In actual operation, when the driving roller 412 rotates, the driven roller 413 and the wire may slip, resulting in the driven roller 413 not rotating and the wire also stopping moving downstream. At this time, the rotating wheel 431 also does not rotate. The encoder 432 feeds back the signal of the stopping rotation to the control mechanism 6. The control mechanism 6 calculates the compensation length of the wire based on the time when the rotating wheel 431 stops rotating and the linear speed of the rotating wheel 431 and the driven roller 413. When the roller assembly 41 resumes normal operation, the control mechanism 6 can control the roller assembly 41 to transmit the compensation length, and then control the cutting mechanism 5 to cut the wire. In this way, the number of defective products cut can be reduced and the waste of materials can be reduced. In the above, when the roller assembly 41 slips, the control mechanism 6 will send an alarm signal to attract the attention of the operator, eliminate the fault, and restore the normal operation of the device.

[0076] To reduce slippage of the roller assembly 41, the surface of the active roller 412 is provided with anti-slip grooves to increase the friction between the wire and the active roller 412. Furthermore, the active roller 412 is made of stainless steel, and the passive roller 413 is made of a material with a certain elasticity, such as plastic or rubber. This allows for a certain amount of deformation in the gap between the active roller 412 and the passive roller 413, thereby reducing deformation of the wire when passing through the roller assembly 41.

[0077] Further, such as Figure 9 and Figure 10As shown, a through slot 4111 with an upward opening is provided on the mounting seat 411 along a direction perpendicular to the transmission direction of the wire. The two ends of the rotating shaft of the driven roller 413 are respectively inserted into the through slots 4111 of the two mounting seats 411, and the two ends of the rotating shaft of the driven roller 413 are respectively connected to the limiting mechanism 414. The limiting mechanism 414 is fixed on the mounting seat 411 and is used to adjust the position of the driven roller 413 and the driving roller 412, that is, to adjust the size of the gap between the driving roller 412 and the driven roller 413, so that the roller assembly 41 can adapt to the passage of wires of different specifications, thereby improving its applicability. Specifically, the limiting mechanism 414 includes a limiting plate and an adjusting rod. The limiting plate is fixed on the mounting seat 411. A threaded hole is provided on the limiting plate. The adjusting rod is passed through the threaded hole. The lower end of the adjusting rod is connected to the rotating shaft of the driven roller 413. By changing the length of the adjusting rod passing through the threaded hole, the distance between the driven roller 413 and the active roller 412 can be adjusted.

[0078] Such as Figure 1 and Figure 2 As shown, the wire cutting device further includes a wire guide mechanism 7, which is disposed between the traction feedback mechanism 4 and the cutting mechanism 5. The wire guide mechanism 7 is hollow, with an inner cavity in the shape of a truncated cone. The inner diameter of the wire guide structure gradually decreases along the direction of wire transmission. The wire guide structure supports and guides the wire transmitted between the traction feedback mechanism 4 and the cutting mechanism 5. The aforementioned shape of the wire guide mechanism 7 enables a smooth transition of the wire from the traction feedback mechanism 4 to the cutting mechanism 5. The outlet of the wire guide mechanism 7 is disposed correspondingly to the cutting blade 321 of the cutting mechanism 5. To further enhance the smooth transition of the wire to the cutting mechanism 5 and prevent deformation of the wire during transmission within the wire guide mechanism 7, the inner diameter of the output end of the wire guide mechanism 7 is slightly larger than the outer diameter of the wire. For example, the inner diameter of the output end of the wire guide mechanism 7 is one-third larger than the outer diameter of the wire.

[0079] like Figure 1 and Figure 3 As shown, the wire cutting device also includes a connection area 8, which is in the form of a trough with an upward opening. It is located on the upper surface of the frame 1, downstream of the cutting mechanism 5. At least one side wall of the connection area 8 along the wire feeding direction is provided with an inclined surface 81, so that the width of the bottom of the trough of the connection area 8 is smaller than the width of the trough opening. After being cut by the cutting mechanism 5, the wire falls directly into the connection area 8. The provision of the inclined surface 81 allows the falling wire to slide along the inclined surface 81 to the bottom of the connection area 8, providing a certain buffering effect on the wire and facilitating the collection of the wires.

[0080] How this application works:

[0081] Before the device of the present application is activated, the wire on the spool 224 is first drawn out, passed through the wire fixing groove 311 on the mold 31 of the stripping mechanism 3, and then extended through the traction feedback mechanism 4 to the wire guide mechanism 7. The distance between the cutter 321 of the cutting assembly 32 and the wire fixing groove 311 is adjusted, and parameters such as the length of the wire insulation to be stripped, the length of a single wire to be cut, the number of wires to be cut, and the rotation speed of the third driving member 42 are input through the touch screen of the control mechanism 6. When the device is activated, the feeding mechanism 2 drives the spool assembly 22 to rotate via the first driving member 21, correcting the angle of the wire to prevent it from twisting. When the wire passes through the wire fixing groove 311, the second driving member 35 drives the cutting assembly 32 to cut the wire insulation according to the preset length. After passing through the stripping mechanism 3, the wire enters the traction feedback mechanism 4, where the traction feedback mechanism 4 calculates the transmission length of the wire. The wire is then transmitted to the cutting mechanism 5 through the wire guide mechanism 7 and cut according to the preset length. If the roller assembly 41 slips when the wire passes through the traction feedback mechanism 4, the encoder 432 feeds back the slip information to the control mechanism 6. The control mechanism 6 calculates the length of the wire to be compensated for according to the slip time, and compensates for the lost length after the roller assembly 41 resumes work, so that the cutting mechanism 5 can cut the wire according to the preset length.

[0082] When the material to be cut is not a stranded wire, the feeding mechanism 2 may not need to calibrate the material.

[0083] To sum up, the present application sets a first driving member 21 to be rotatably connected with the spool assembly 22, and sets the shape of the wire fixing groove 311 on the mold 31 of the stripping mechanism 3 to be consistent with the shape of the wire, so that the wire is limited by the wire fixing groove 311, and the spool assembly 22 is driven to rotate by the first driving member 21 to correct the wire, thereby avoiding twisting of the wire and causing the cutting depth of the cutter 321 to change, thereby affecting the stripping effect of the wire.

[0084] In addition, by providing the traction feedback mechanism 4 to calculate the transmission length of the wire and feedback the slip information of the roller assembly 41, the accuracy of the wire cutting length is improved, the defective rate of the product is reduced, and the waste of raw materials is reduced.

[0085] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of this application, and all these changes or substitutions should fall within the scope of protection of the claims attached to this application.
