Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a clamping and traction mechanism for a cable length stripping device. Background Technology

[0002] As a fundamental component for electrical connections and signal transmission, cables are widely used in communications, automated machinery, and automotive electronics. During cable manufacturing, it is often necessary to cut coiled continuous cables to specific lengths according to actual application requirements and strip the insulation from both ends of the cut cables. The accuracy of the cut cable length directly affects the quality and stability of subsequent assembly processes such as terminal crimping and mating: if the cable is too long, the excess portion will press against the connector housing after being inserted, preventing the terminals from locking properly; if the cable is too short, the wire core cannot be effectively pressed into the terminal, affecting the overall strength of the terminal and the reliability of the electrical connection. Especially in fields with high cable reliability requirements, such as automotive wiring harnesses and aerospace, the length error of a single cable must often be controlled within ±0.5mm.

[0003] Currently, existing cable length cutting and stripping devices on the market typically use a drive motor to rotate upper and lower traction wheels. The friction between the traction wheels and the cable clamps and transports the cable. Once the cable reaches a set position, a cutting mechanism cuts it, and a stripping mechanism peels off the insulation from both ends. However, this method relies on friction to propel the cable forward. When the cable surface is oily or the traction wheel surface is worn, relative slippage can easily occur between the traction wheel and the cable. This results in a discrepancy between the number of rotations of the traction wheel and the actual length of cable transported, reducing the consistency of the cut length between different batches of cables. Furthermore, during cable traction or stripping, the cable is under tension, causing the insulation and internal conductors to elongate axially within their elastic range. After cutting or stripping, the cable shrinks, resulting in an actual length shorter than the set value, severely affecting the accuracy of cable length cutting. Therefore, it is necessary to improve existing cable length cutting and stripping devices to enhance the accuracy of cable length cutting and improve the consistency of cable length. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping and traction mechanism for a cable length-cutting device, which has the advantages of improving the accuracy of cable length-cutting and the consistency of cable length.

[0007] The present invention is further configured such that: the cable floating clamping assembly includes a cable synchronous clamping cylinder fixedly connected to the traction sliding seat along the direction perpendicular to the cable conveying direction; the clamping end of the cable synchronous clamping cylinder is symmetrically fixedly connected to a cable fixing clamping block for clamping the cable; a floating groove is formed in the cable fixing clamping block along the direction parallel to the cable conveying direction; a cable floating clamping block for clamping the cable is slidably connected in the floating groove; and a return spring is fixedly connected between the side of the floating groove away from the cable traction direction and the cable floating clamping block.

[0008] The present invention is further configured such that: a laser displacement sensor for detecting the floating distance of the cable floating clamp block in the floating groove is fixedly connected to one end of the cable fixing clamp block away from the reset spring, and the laser displacement sensor is electrically connected to the cable compensation and conveying assembly.

[0009] The present invention is further configured such that: the cable compensation conveying assembly includes a lower conveying wheel and an upper compensation driving wheel respectively rotatably connected to the base; a compensation servo motor is fixedly connected to the base to drive the upper compensation driving wheel to rotate and drive the cable to be fed backward for length compensation; and friction sleeves for preventing cable slippage are sleeved and fixedly connected to the lower conveying wheel and the upper compensation driving wheel.

[0010] The present invention is further configured such that: the intermediate clamping assembly includes a cable clamping block slidably connected to the base along the direction perpendicular to the cable conveying direction based on a first lifting cylinder, and a cable guide clamping groove formed on the cable clamping block along the direction of cable conveying for guiding cable conveying; a clamping sliding seat is slidably connected to the base along the direction perpendicular to the cable conveying direction based on a clamping guide rail; a clamping electric cylinder is fixedly connected to the base to drive the clamping sliding seat to slide; and a cable clamping block for clamping and fixing the cable in the cable guide clamping groove is fixedly connected to the clamping sliding seat.

[0011] The present invention is further configured such that: a plurality of pressure sensors for detecting clamping force are provided at intervals between the cable clamping block and the clamping sliding seat, and the pressure sensors are electrically connected to the clamping electric cylinder.

[0012] The present invention is further configured such that: the cable cutting assembly includes a cutting seat slidably connected to the base along the direction perpendicular to the cable conveying direction based on a second lifting cylinder, and a cable guide cutting groove formed on the cutting seat along the direction of cable conveying; a cutting sliding seat is slidably connected to the base along the direction perpendicular to the cable conveying direction based on a cutting guide rail; a cutting cylinder is fixedly connected to the base to drive the cutting sliding seat to slide; an elastic pressure plate for pressing the cable into the cable guide cutting groove is movably connected to the end of the cutting sliding seat near the intermediate clamping assembly based on a compression spring to avoid stretching the cable body during the cable cutting process; a cable cutting blade is fixedly connected to the end of the cutting sliding seat away from the intermediate clamping assembly; and a cable cutting groove is formed on the cutting seat.

[0013] The present invention is further configured such that: the cable stripping assembly includes a reciprocating sliding seat that is slidably connected to the base along a horizontal stripping guide rail parallel to the cable conveying direction, and a stripping cylinder fixedly connected to the base for driving the reciprocating sliding seat to slide and strip the cable. The reciprocating sliding seat has stripping sliding seats symmetrically slidably connected to the vertical stripping guide rail along a direction perpendicular to the cable conveying direction. The stripping sliding seat has symmetrically fixedly connected slit cylinders for driving the stripping sliding seat to slide. The stripping sliding seat has a slit block fixedly connected to it, and the slit block has a slit groove for cutting a slit in the cable to facilitate the stripping of the insulation layer.

[0014] In summary, the present invention has the following beneficial effects: 1. The cable floating clamping assembly of the present invention achieves fixed-length traction through a lead screw traction assembly. During the traction process, the cable simultaneously undergoes both resettable elastic deformation and non-resettable plastic deformation under axial tension. When the cable is pulled into position, the cable floating clamping block slides backward along the floating groove under the action of the return spring, thereby causing the cable end to elastically reset backward to release the axial elastic tension generated by the cable during traction. Simultaneously, a laser displacement sensor measures the position of the cable floating clamping block before cable traction and after cable traction and reset. The displacement difference obtained from the two measurements is... The displacement difference is fed back to the compensation servo motor of the cable compensation conveying component in the form of an electrical signal. The compensation servo motor drives the upper compensation drive wheel to rotate in the opposite direction through this difference, thereby driving the cable to be sent back by a distance exactly equal to the elongation caused by plastic deformation, so as to offset the increase in cable length caused by plastic deformation. This makes the actual length of the cut cable in the free state exactly equal to the required set length of the cable, eliminating the length error caused by material deformation during the cable pulling process, improving the accuracy of fixed-length cable cutting and the consistency of cable length. 2. By setting an intermediate clamping component between the cable floating clamping component and the cable compensation conveying component, after the cable is pulled into place and length compensation is completed, the clamping electric cylinder of the intermediate clamping cylinder pushes the cable clamping block to clamp and fix the main body of the cable in the cable guide clamping groove. This achieves position locking of the main body of the cable during cable cutting and stripping, preventing the tensile deformation generated during cable cutting and stripping from being transmitted to the main body of the cable, and significantly reducing the tensile deformation of the cable during cable cutting and stripping. At the same time, the cable cutting component sets an elastic lower pressure plate with a compression spring at one end of the cutting slide seat near the intermediate clamping component, so that the side of the cable near the intermediate clamping component remains fixed during the cutting process, further shortening the length of the cable that undergoes tensile deformation during the cable cutting process, and further ensuring the consistency of the cable length after cutting and stripping.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: refer to Figure 1A clamping and traction mechanism for a cable length-cutting device includes a base 1. A cable floating clamping assembly 3, based on a screw traction assembly 2 and movably connected along the cable conveying direction, is mounted on the base 1. This assembly clamps the cable end and elastically resets the cable after it is pulled into position. A cable compensation conveying assembly 4, fixedly connected to the end of the cable along the conveying direction, drives the cable backward to compensate for the increase in length caused by plastic deformation during cable traction. During traction, the cable simultaneously undergoes resettable elastic deformation and non-resettable plastic deformation under axial tension. The elastic deformation is reset by the cable floating clamping assembly 3 after the traction force is lost, while the plastic deformation does not. The cable will reset, resulting in an irreversible increase in length after traction. The cable compensation conveying component 4 then feeds the cable back to compensate for the increase in length caused by plastic deformation, ensuring that the overall length of the cable is equal to the set cable length. The base 1 has an intermediate clamping component 5 fixedly connected between the cable floating clamping component 3 and the cable compensation conveying component 4 to clamp the cable body and prevent the transmission of tensile deformation to the cable body during cutting or stripping. The base 1 has a cable cutting component 6 between the cable compensation conveying component 4 and the intermediate clamping component 5 for cutting the cable. The base 1 has a cable stripping component 7 between the intermediate clamping component 5 and the cable floating clamping component 3.

[0019] refer to Figure 4 Specifically, the lead screw traction assembly 2 includes a lead screw traction seat 21 fixedly connected to the base 1 and a traction lead screw shaft 22 rotatably connected to the lead screw traction seat 21 along a direction parallel to the cable conveying direction. A traction drive motor 23 that drives the traction lead screw shaft 22 to rotate is fixedly connected to the lead screw traction seat 21. A traction sliding seat 24 for mounting the cable floating clamp assembly 3 is slidably connected to the lead screw traction seat 21 along a direction parallel to the cable conveying direction. A lead screw nut 25 that cooperates with the traction lead screw shaft 22 is fixedly connected to the traction sliding seat 24. The traction drive motor 23 of the lead screw traction assembly 2 drives the traction lead screw shaft 22 to rotate, and drives the traction sliding seat 24 and the cable floating clamp assembly 3 to slide along the cable conveying direction through the lead screw nut 25, thereby realizing the traction of the cable.

[0020] refer to Figure 4 and Figure 5Specifically, the cable floating clamping assembly 3 includes a cable synchronous clamping cylinder 31 movably connected to the traction sliding seat 24 along the direction perpendicular to the cable conveying direction. The clamping end of the cable synchronous clamping cylinder 31 is symmetrically fixedly connected to a cable fixing clamping block 32 for clamping the cable. A floating groove 33 is provided in the cable fixing clamping block 32 along the direction parallel to the cable conveying direction. A cable floating clamping block 34 for clamping the cable is slidably connected in the floating groove 33. A return spring 35 is fixedly connected between the floating groove 33 and the cable floating clamping block 34 on the side of the floating groove 33 away from the cable traction direction. A laser displacement sensor 36 is fixedly connected to the end of the cable fixing clamping block 32 away from the return spring 35. This sensor is used to detect the floating distance of the cable floating clamping block 34 within the floating groove 33. The laser displacement sensor 36 is electrically connected to the cable compensation and conveying assembly 4. When clamping the cable, the cable fixing clamping block 32 is driven to merge by the cable synchronous clamping cylinder 31, thereby clamping and fixing the cable between the cable floating clamping blocks 34. During the cable traction process, the return spring 35 is stretched. When the traction sliding seat 24 moves the cable end to the set cable length, the screw traction assembly 2 stops. During traction, the cable floating clamping block 34 slides backward along the floating groove 33 under the action of the return spring 35, thereby causing the cable head end to elastically reset backward to release the axial elastic tension generated by the cable during traction. At the same time, the position of the cable floating clamping block 34 is measured by the laser displacement sensor 36 before cable traction and after cable traction and reset. The displacement difference obtained from the two measurements is fed back to the cable compensation and conveying component 4 in the form of an electrical signal, thereby driving the cable to be sent back a distance equal to the displacement difference to offset the increase in cable length caused by cable plastic deformation.

[0021] refer to Figure 1 and Figure 2 Specifically, the cable compensation conveying assembly 4 includes a lower conveying wheel 41 and an upper compensation drive wheel 42 rotatably connected to the base 1. A compensation servo motor 43 is fixedly connected to the base 1 to drive the upper compensation drive wheel 42 to rotate and drive the cable backward for length compensation. Friction sleeves 44 are fixedly connected to the lower conveying wheel 41 and the upper compensation drive wheel 42 to prevent cable slippage. After receiving the displacement difference data from the laser displacement sensor 36, the compensation servo motor 43 drives the upper compensation drive wheel 42 to rotate in the opposite direction, thereby driving the cable backward by a distance precisely equal to the plastic deformation elongation to offset the increase in cable length caused by plastic deformation. By setting the friction sleeve 44, the possibility of slippage between the cable and the upper compensation drive wheel 42 and the lower conveying wheel 41 can be reduced, ensuring the accuracy of cable length compensation. During the backward cable compensation process, the lead screw traction assembly 2 synchronously drives the cable forward to prevent further stretching of the cable.

[0022] refer to Figure 2Specifically, the intermediate clamping assembly 5 includes a cable clamping block 51 slidably connected to the base 1 along the direction perpendicular to the cable conveying direction based on a first lifting cylinder 58, and a cable guide clamping groove 52 formed on the cable clamping block 51 along the direction of cable conveying for guiding cable conveying. A clamping slide seat 54 is slidably connected to the base 1 along the direction perpendicular to the cable conveying direction based on a clamping guide rail 53. A clamping electric cylinder 55 is fixedly connected to the base 1 to drive the clamping slide seat 54 to slide. A cable clamping block 56 for clamping and fixing the cable in the cable guide clamping groove 52 is fixedly connected to the clamping slide seat 54. The clamping electric cylinder 55 of the intermediate clamping cylinder pushes the cable clamping block 56. The main body of the cable is clamped and fixed within the cable guide clamping groove 52, thereby locking the position of the cable body during cable cutting and stripping. This prevents the tensile deformation generated during cable cutting and stripping from being transmitted to the cable body, significantly reducing the tensile deformation of the cable during the cutting and stripping process. Several pressure sensors 57 for detecting clamping force are spaced apart between the cable clamping block 56 and the clamping sliding seat 54. The pressure sensors 57 are electrically connected to the clamping electric cylinder 55. The pressure sensors 57 prevent excessive pressure from acting on the cable body, which could cause cable deformation. When the pressure sensor 57 senses that the pressure has reached a set value, it sends a control signal, and the clamping electric cylinder 55 stops extending. In this embodiment, the length of the cable body is not less than 80% of the required cable length.

[0023] refer to Figure 2 Specifically, the cable cutting assembly 6 includes a cutting seat 61 slidably connected to the base 1 along the direction perpendicular to the cable conveying direction based on the second lifting cylinder 610, and a cable guide cutting groove 62 opened on the cutting seat 61 along the direction of cable conveying. A cutting sliding seat 64 is slidably connected to the base 1 along the direction perpendicular to the cable conveying direction based on the cutting guide rail 63. A cutting cylinder 69 is fixedly connected to the base 1 to drive the cutting sliding seat 64 to slide. At one end of the cutting sliding seat 64 near the intermediate clamping assembly 5, a clamping spring 65 is movably connected to press the cable into the cable guide cutting groove. An elastic pressure plate 66 is provided inside the 62 to prevent the cable body from being stretched during the cable cutting process. A cable cutting blade 67 is fixedly connected to the end of the cutting slide seat 64 away from the intermediate clamping component 5. A cable cutting groove 68 is provided on the cutting seat 61. The cable cutting component 6 sets the elastic pressure plate 66 at the end of the cutting slide seat 64 near the intermediate clamping component 5 through a compression spring 65, so that the side of the cable near the intermediate clamping component 5 is kept fixed during the cutting process, which further shortens the length of the cable that is stretched and deformed during the cable cutting process, and further ensures the consistency of the cable length after stripping.

[0024] refer to Figure 1 and Figure 3Specifically, the cable stripping assembly 7 includes a reciprocating sliding seat 72 that is slidably connected to the base 1 along a horizontal stripping guide 71 parallel to the cable conveying direction, and a stripping cylinder 73 fixedly connected to the base 1 for driving the reciprocating sliding seat 72 to slide and strip the cable. A stripping sliding seat 75 is symmetrically slidably connected to the reciprocating sliding seat 72 along a vertical stripping guide 74 perpendicular to the cable conveying direction. A slit air cylinder 75 is symmetrically fixedly connected to the stripping sliding seat 75 to drive the stripping sliding seat 75 to slide. The stripping cylinder 76 has a slit block 77 fixedly connected to the stripping slide seat 75. The slit block 77 has a slit groove 78 for cutting a slit in the cable to facilitate the stripping of the insulation layer. During the stripping of the insulation layer at the end of the cable, the slit cylinder 76 of the cable stripping assembly 7 drives the stripping slide seat 75 to close, so that the slit groove 78 on the slit block 77 cuts into the insulation layer at the end of the cable. Then, the stripping cylinder 73 drives the reciprocating slide seat 72 to slide forward or backward along the direction parallel to the cable conveying direction to strip the insulation layer.

[0025] Brief description of the usage process: First, the cable synchronous clamping cylinder 31 of the cable floating clamping assembly 3 drives the cable clamping fixing blocks to merge, thereby clamping and fixing the cable end between the cable floating clamping blocks 34; then, the traction drive motor 23 of the screw traction assembly 2 drives the traction screw shaft 22 to rotate, and drives the traction sliding seat 24 and the cable floating clamping assembly 3 to slide along the cable conveying direction through the screw nut 25, thereby realizing the traction of the cable. During this process, the return spring 35 is stretched. When the traction sliding seat 24 drives the cable end to move the set cable length, the screw traction assembly... When component 2 stops traction, the cable floating clamp block 34 slides backward along the floating groove 33 under the action of the return spring 35, thereby causing the cable end to elastically reset backward to release the axial elastic tension generated by the cable during traction. At the same time, the position of the cable floating clamp block 34 is measured by the laser displacement sensor 36 before cable traction and after cable traction and reset. The displacement difference obtained from the two measurements is fed back to the compensation servo motor 43 of the cable compensation conveying component 4 in the form of an electrical signal. The compensation servo motor 43 drives the compensation drive wheel 42 in reverse direction based on the difference. The rotation causes the cable to be fed backward a distance precisely equal to the elongation due to plastic deformation, thus offsetting the increase in cable length caused by plastic deformation. Subsequently, the clamping cylinder 55 of the intermediate clamping assembly 5 pushes the cable clamping block 56 to clamp and fix the cable body within the cable guide clamping groove 52. Then, the cutting cylinder 69 of the cable cutting assembly 6 pushes the cutting sliding seat 64 downward, and the elastic lower pressure plate 66 first contacts the cable and presses it firmly onto the cutting seat 61. The cable cutting blade 67 then cuts the cable. Finally, the cable stripping assembly 7 sequentially strips the insulation from the cable head and tail ends. The insulation layer is stripped. During the stripping of the cable head end, the slit cylinder 76 of the cable stripping assembly 7 drives the stripping slide seat 75 to close, so that the slit groove 78 on the slit block 77 cuts into the insulation layer of the cable end. Then, the stripping cylinder 73 drives the reciprocating slide seat 72 to move backward along the direction parallel to the cable conveying direction, thereby stripping the insulation layer. When stripping the cable tail end, the cable tail end is conveyed to the station of the cable stripping assembly 7 by the lead screw traction assembly 2. Then, the insulation layer of the cable tail end is stripped. After the stripping is completed, the cable clamping and conveying assembly releases the clamp, and the cable falls to the receiving station.
