Description

Technical Field

[0001] The present application relates to the technical field of cable connection, and in particular to an automatic wiring device for low-voltage live cables. Background Art

[0002] Traditional cable wiring technology mainly uses mechanical fixing. Although the cost is low, it is easy to cause poor contact at the joints during long-term use due to the natural aging of the cables, environmental factors and frequent plugging and unplugging operations, which in turn affects the stability and reliability of the circuit. Especially in the case of high-frequency signal transmission and high current, wiring quality problems may cause equipment damage or signal interference, thus affecting the performance of the entire system.

[0003] Therefore, in order to improve the wiring effect of the cable, it is necessary to improve the existing mechanical fixing method. For example, the patent application with publication number CN112563862B discloses a quick wiring device for low-voltage wires, wherein the peeling module includes a rotating cylinder detachably connected to the U-shaped base, and a serrated knife head is arranged inside the rotating cylinder; wherein the twisting module includes a twisting head, a screw and a rocker handle; the joint part after twisting is firmly joined and not easy to loosen, and the wiring effect is good, avoiding problems such as poor contact or falling of the wire joints after wiring; at the same time, the insulating tape fixed on the twisting head can also insulate and protect the wiring head of the wire while wiring, saving operation time.

[0004] However, the above-mentioned prior art still has some defects when it comes to cable wiring: when the cables are freely released into the environment after wiring, the cables will be affected by their own gravity and external environmental factors such as wind, etc. These factors will generate greater stress at the cable wiring points, and the cable connections are more likely to fall off than the complete cable sections. Under long-term action, this excessive stress may not only cause the wiring points to loosen, but in severe cases may even cause the cables to break, thereby affecting the wiring effect of the cables.

[0005] Based on the above background, in the existing cable wiring technology, improving the cable fixing method to reduce the influence of external factors on the stress of the cable wiring, thereby improving the wiring stability and durability of the cable, is still one of the technical problems to be solved. To this end, it is necessary to effectively alleviate the above problems and further improve the reliability and long-term stability of cable wiring. Summary of the invention

DETAILED DESCRIPTION

[0040] The following is combined with Figures 1 to 9 This application is described in further detail.

[0041] The embodiment of the present application discloses an automatic wiring device for low-voltage live cables. By performing winding insulation treatment on the cable connection, the electrical stress and mechanical stress between the cable connection section and the cable body can be effectively reduced, thereby improving the stability and fixing effect of the connection section; at the same time, the fixing method of the cable connection section and the cable is standardized to ensure that the cable connection section will not be displaced or loosened due to the application of external force, further reducing the force on the cable connection section, thereby enhancing the reliability of the cable connection section in the overall cable structure.

[0042] Embodiment 1:

[0043] Reference Figure 1 and Figure 2 An automatic wiring device for low-voltage live cables includes a fixed frame 1 with an inverted T-shaped structure, a winding mechanism 2 is installed on the horizontal section of the fixed frame 1, and a fixing mechanism 3 is installed on the vertical section of the fixed frame 1.

[0044] The winding mechanism 2 comprises: a horizontal frame 21, which is installed on the horizontal section of the fixed frame 1, and a movable frame 22 is slidably arranged on the horizontal frame 21 and reciprocates along the horizontal direction thereof.

[0045] The winding disc 23 is rotatably installed on the moving frame 22 , and through holes matching with the cables are symmetrically provided on the winding disc 23 along the height direction of the moving frame 22 .

[0046] The adhesive tape 24 is arranged on the movable frame 22 and rotates circumferentially along the winding disc 23 to perform insulation winding on the cable connection to form a cable connection section.

[0047] The winding mechanism 2 first uses tape 1 24 to wrap the connection between the two cables to form a cable connection section, and then uses tape 2 33 to further fix the cable connection section on the cable, thereby effectively transferring the stress at the cable connection to the connection part between tape 2 33 and the cable, reducing the stress concentration at the cable connection, avoiding the risk of loosening or breaking due to excessive stress at the connection point, and thus improving the overall reliability and stability of the cable connection.

[0048] Reference Figures 2 to 4 The horizontal frame 21 is provided with a driving mechanism 4 for driving the moving frame 22 to move and the winding disc 23 to rotate, and the driving mechanism 4 includes:

[0049] The vertical protrusion 42 is disposed on the horizontal frame 21 , and a threaded rod 43 extending along the length direction of the horizontal frame 21 is installed on the vertical protrusion 42 , and one end of the threaded rod 43 away from the vertical protrusion 42 passes through the movable frame 22 .

[0050] The threaded rod 41 is mounted on the vertical protrusion 42 through a bearing, and one end of the threaded rod 41 away from the vertical protrusion 42 is mounted on the moving frame 22 through a threaded connection.

[0051] The driving assembly 44 is installed on the moving frame 22 and is used to drive the winding disc 23 to rotate.

[0052] The driving assembly 44 includes: an annular rack plate 441, which is installed on one side of the winding disk 23 close to the vertical protrusion 42.

[0053] The sleeve 442 is sleeved on the threaded rod 43 and abuts against the movable frame 22, and is transmission-connected to the threaded rod 43 by a threaded connection.

[0054] Gear 1 445 is mounted on sleeve 442 and meshes with annular rack plate 1 441 .

[0055] An annular stripping knife 443 is installed on the end surface of the winding disk 23 close to the vertical protrusion 42, and a plurality of cutting protrusions 444 are evenly arranged on the annular stripping knife 443 along its circumference.

[0056] The through hole is provided with a guiding slope for making way for the cable, and the two ends of the cable are clamped and limited by existing pneumatic grippers respectively. The pneumatic grippers are prior art, so they are not explained again and are not shown in the figure. A driving motor (not shown in the figure) is installed at the end of the threaded rod 41 away from the movable frame 22. The driving motor is used to drive the threaded rod 41 to rotate. At this time, the annular stripping knife 443 is moved by external force so that the blade of the annular stripping knife 443 is inserted into the inner part of the cable insulation layer.

[0057] During specific work, the end of the cable away from the pneumatic gripper is passed through the through hole. At this time, the cable passes through the annular stripping knife 443 synchronously. At this time, the drive motor is started. The drive motor drives the threaded rod 41 to rotate during the rotation of the drive shaft. During the rotation of the threaded rod 41, the movable frame 22 is driven to move toward the side of the vertical protrusion 42 through the threaded connection. At this time, the annular stripping knife 443 is in the process of synchronous movement. The multiple cutting protrusions 444 thereon cooperate with each other to effectively strip the cable insulation layer and cut it in time, so that the stripped cable insulation layer is naturally divided into four petals. This can avoid operational difficulties and possible damage caused by the inability to directly push the insulation layer off the cable after stripping the cable insulation layer.

[0058] The movable frame 22 synchronously drives the sleeve 442 to move during the movement. During the movement of the sleeve 442, the sleeve 442 cooperates with the threaded rod 43 to rotate synchronously through a threaded connection. During the rotation of the sleeve 442, the gear 445 and the rack plate 441 are engaged with each other to drive the winding disk 23 to rotate. During the rotation of the winding disk 23, the winding disk 23 cooperates with the through hole to wind and connect the exposed parts of the two cables (that is, the cable connection point), so that the two cables are energized.

[0059] Reference Figure 5 to Figure 6 A moving block 221 that slides circumferentially around the winding disc 23 is provided on one side of the moving frame 22 away from the vertical protrusion 42 , a vertical shaft 222 is installed on the moving block 221 , and the adhesive tape 24 is installed on the vertical shaft 222 .

[0060] A second annular rack plate 223 is installed on the side of the circumference of the winding disc 23 away from the vertical protrusion 42, a second gear 224 meshing with the second annular rack plate 223 is installed on the vertical shaft 1 222, and a third annular rack plate 225 meshing with the second gear 224 is installed on the moving frame 22.

[0061] When the moving frame 22 moves, it will synchronously drive the winding disk 23 to move during the rotation. When the winding disk 23 rotates, it will further drive the annular rack plate 223 to rotate. During the rotation of the annular rack plate 223, the gear 224 cooperates with the annular rack plate 223 to drive the moving block 221 to slide circumferentially around the winding disk 23. The movement of the moving block 221 will drive the vertical shaft 1 222 to move synchronously. During the synchronous movement of the vertical shaft 1 222, the tape 1 24 will be driven to synchronously wrap around the exposed part of the cable, thereby achieving insulation treatment of the exposed part of the external cable, thereby ensuring the insulation and safety of the cable connection section, and preventing leakage of the cable connection section.

[0062] Furthermore, the annular rack plate 223 cooperates with the annular rack plate 3 225 through the gear 224 to form a planetary gear system. The planetary gear system synchronously drives the moving block 221 to move and cooperate with the tape 1 24, effectively reducing the use of external drive and improving the working efficiency and insulation treatment effect of the equipment.

[0063] The fixing mechanism 3 comprises a lifting frame 31 which is arranged to slide in a limited manner along the length direction of the vertical section of the fixing frame 1 .

[0064] The wire-management cylinder 32 is a through-hole structure, and the cable connection section can be wound around the cable. The wire-management cylinder 32 is provided with an adhesive tape 33 for limiting the winding of the cable connection section.

[0065] Reference Figure 7When the cable connection is insulated to form a cable connection section, the wire management cylinder 32 and the connecting block 323 provided by the present invention cooperate with each other to wrap the cable connection section around the cable, further reducing the stress on the cable connection section. Specifically, the wire management cylinder 32 is rotatably installed on the lifting frame 31, and a fixing protrusion 321 is provided at the bottom of the circumferential surface of the wire management cylinder 32. A vertical shaft 322 is installed on the fixing protrusion 321, and the tape 33 is installed on the vertical shaft 322.

[0066] A connecting block 323 for winding the cable connecting section is installed on the cable management cylinder 32.

[0067] During specific operation, when the mobile frame 22 moves to one end of the horizontal frame 21 close to the vertical protrusion 42, the insulation winding work at the cable connection is completed, and a cable insulation section is formed at the cable connection. At this time, the winding disc 23 is completely separated from the exposed part of the cable, and the used tape 24 is cut off by the existing electric cutting knife.

[0068] The lifting frame 31 is driven to move upward by an existing driving slider (not shown in the figure), and the lifting frame 31 simultaneously drives the cable management cylinder 32 to move upward during the upward movement, and the cable management cylinder 32 synchronously rotates during the upward movement. When the cable management cylinder 32 moves up to the cable connection section, the cable management cylinder 32 can drive the cable connection section to rotate around the connection point of the two cables during the upward movement, and make the cable connection section close to the cable above. At this time, the cable management cylinder 32 drives the cable management cylinder 32 to rotate through an external driving force, and the cable management cylinder 32 cooperates with the connecting block 323 during the rotation process to give the cable connection section a spiral upward force. At this time, the spiral upward force can wrap the cable connection section around the cable above, thereby further reducing the possibility of the cable connection section being suspended in the air, and reducing the stress at the cable connection section at this time.

[0069] At the starting position, adhesive tape 2 33 is adhered to the cable below, and during the rotation of the cable management cylinder 32, the fixed protrusion 321 and the vertical axis 2 322 cooperate with each other to drive adhesive tape 2 33 to rotate synchronously, and adhesive tape 2 33 wraps around the cable. When adhesive tape 2 33 moves to the cable connection, adhesive tape 2 33 continues to wrap around and wraps around the rotated cable connection section, so that the cable connection section is further fixed on the cable. The cable connection section is further reinforced at this time, thereby significantly improving the stability and fixing effect of the cable connection section on the cable.

[0070] The cable connecting section wrapped with the adhesive tape 33 forms a whole with the cable, ensuring that the cable connecting section will not be displaced or loosened due to the application of external force, further reducing the stress on the cable connecting section, thereby enhancing the reliability of the cable connecting section in the overall cable structure.

[0071] Reference Figure 8 and Fig. 9In order to further reduce the stress of the cable connection section, the traction rope 312 and the adhesive tape 316 cooperate with each other, which can effectively transfer the stress of the cable connection section to the position where the cable and the traction rope 312 are connected. The bottom of the lifting frame 31 provided by the present invention is equipped with an L-shaped lifting frame 311, and the lifting frame 311 is provided with a traction rope 312 for protecting the cable connection section. A through groove 313 matching with the cable is opened on the horizontal section of the lifting frame 311, and an electric slider 314 circumferentially sliding around the through groove 313 is provided on the horizontal section of the lifting frame 311. A vertical shaft 315 is installed on the electric slider 314, and an adhesive tape 316 for fixing the traction rope 312 is installed on the vertical shaft 315.

[0072] The horizontal section of the lifting frame 311 is symmetrically provided with vertical frames 317 along its width direction, and rotating rollers 318 are installed between the vertical frames 317 through bearings, and the traction rope 312 is wound around the rotating rollers 318. A vertical connecting frame 319 is installed on the lifting frame 311, and a reversing shaft 310 for reversing the traction rope 312 is installed on the vertical connecting frame 319 through a bearing.

[0073] The rotating roller 318 is connected to the vertical frame 317 by a ratchet and pawl transmission method, that is, the rotating roller 318 intermittently releases the traction rope 312 to avoid the traction rope 312 being scattered on the lifting frame 311 during a single release of the rotating roller 318, affecting the release effect of the traction rope 312, and in this process, the existing pneumatic gripper is used to grab the tape three 316 and make the tape three 316 adhere to the cable. During specific operation, the traction rope 312 is adhered to the cable at the starting position, and the lifting frame 31 drives the lifting frame 311 to move upward, the traction rope 312 is released from the rotating roller 318 and the line is released. During the release process of the traction rope 312, the vertical connecting frame 319 and the reversing shaft 310 cooperate with each other to reverse the traction rope 312, so that the horizontally moving traction rope 312 moves along the length direction of the cable after reversing, and at this time the traction rope 312 is close to the cable.

[0074] After the lifting frame 311 rises a certain distance, the lifting frame 311 stays at the height for a short period of time. At this time, the existing pneumatic gripper (not shown in the figure) drives the tape three 316 to adhere to the cable, and the electric slider 314 is started. The electric slider 314 rotates around the cable for a certain number of circles. At this time, the electric slider 314 cooperates with the vertical axis three 315 to drive the tape three 316 to wrap around the cable with the traction rope 312. When the wrapping is completed, the tape three 316 is cut off by the existing cutting knife (not shown in the figure). At this time, the wrapped tape three 316 forms a rubber ring to fix the traction rope 312 on the cable.

[0075] By repeating the above steps, the traction rope 312 can be fixed to the cable through the evenly distributed rubber rings. At the same time, the traction rope 312 is fixedly connected to the cable at the cable connecting section. Therefore, through the cooperation between the traction rope 312 and the adhesive tape 316, the stress on the cable connecting section can be effectively transferred to the connection position between the cable and the traction rope 312, thereby further enhancing the stability of the cable wiring and ensuring that the cable is safer and more reliable during use.

[0076] In order to facilitate the winding of the adhesive tape 316, the lifting frame 31 designed in the present invention can be wound intermittently during the above process, so that the adhesive tape 316 can intermittently wind the cable tied with the traction rope 312.

[0077] Embodiment 2:

[0078] Reference Figure 8 and Fig. 9 On the basis of the first embodiment, even if the cable connecting section is fixed on the cable, when the wind force is too strong, the connection performance between the second adhesive tape 33 and the cable may be reduced, and the connection point of the two cables may still be affected by external forces. In order to further improve the cable connecting section from being affected by other external forces, the push rod 51 of the present invention can push the two cable connection points to form a certain arc, and then reduce the stress of the two cable connection points through the cooperation of the traction rope 312 and the third adhesive tape 316. Specifically, a push rod 5 is slidably provided through the end of the lifting frame 311 away from the vertical connecting frame 319, and an inclined section is provided at the bottom of the push rod 5. A push rod 51 for pushing the cable is installed on the top of the vertical section of the push rod 5, and an elastic telescopic rod 52 for resetting the push rod 5 is installed on the lifting frame 311 through a fixed block.

[0079] During specific operation, when the lifting frame 311 moves to the cable connecting section, the pneumatic gripper that clamps the lower cable releases the corresponding cable. At this time, the inclined section of the pushing rod 5 abuts against the horizontal frame 21. At this time, the lifting frame 311 continues to move. During the movement of the lifting frame 311, the inclined section of the pushing rod 5 is driven to move synchronously. At this time, the inclined section of the pushing rod 5 abuts against the horizontal frame 21 and drives the pushing rod 5 to move to one side of the cable. The elastic telescopic rod 52 is compressed at this time, and during the movement of the pushing rod 5, the pushing rod 51 is driven to push the cable connecting section to move a certain distance. At this time, the lower cable connecting section has been separated from the pneumatic gripper and moves up a certain distance. The starting gripper that clamps the lower cable is started again to clamp the lower cable.

[0080] When the tilting section of the push rod 5 is separated from the horizontal frame 21, the elastic telescopic rod 52 is reset and drives the push rod 5 to reset synchronously. At this time, the push rod 5 no longer pushes the cable to move. Since the pneumatic gripper has clamped the cable below, the cable will not reset due to gravity, resulting in the cable connection section being unable to reset. Due to the continuous pushing of the push rod 51, the cable connection section forms a certain arc, that is, a distance protruding outward is generated between the two cable connection points.

[0081] By using adhesive tape 316 to fix the adjusted curved cable connection section on the traction rope 312, even if the cable is shaking, the stress at the cable connection can be transferred to the nearest and adjacent rubber ring through the combined action of the traction rope 312 and adhesive tape 316, so that the two cable connection points no longer bear any force, thereby ensuring that the traction rope 312 can effectively transfer the stress at the cable connection to the connection position of the traction rope 312 connected to the cable, thereby better ensuring the cable wiring effect.

[0082] The implementation principle of the present invention is:

[0083] (1): Pass the end of the cable away from the pneumatic gripper through the through hole. At this time, the cable passes through the annular stripping knife 443 synchronously. At this time, the drive motor is started. The drive motor drives the threaded rod 41 to rotate during the rotation of the drive shaft. During the rotation of the threaded rod 41, the movable frame 22 is driven to move toward the side of the vertical protrusion 42 through the threaded connection. At this time, the annular stripping knife 443 can effectively strip the cable insulation layer and cut it in time during the synchronous movement by using the multiple cutting protrusions 444 thereon to cooperate with each other, so that the stripped cable insulation layer is naturally divided into four petals.

[0084] (2): The movable frame 22 synchronously drives the sleeve 442 to move during the movement. During the movement of the sleeve 442, the sleeve 442 cooperates with the threaded rod 43 to rotate synchronously through a threaded connection. During the rotation of the sleeve 442, the gear 445 and the annular rack plate 441 are meshed with each other to drive the winding disk 23 to rotate. During the rotation of the winding disk 23, the winding disk 23 cooperates with the through hole to wrap and connect the exposed parts of the two cables (i.e., the cable connection).

[0085] (3): When the moving frame 22 moves, it will synchronously drive the winding disk 23 to move during the rotation process. When the winding disk 23 rotates, it will further drive the annular rack plate 223 to rotate. During the rotation of the annular rack plate 223, the gear 224 cooperates with the annular rack plate 223 to drive the moving block 221 to slide circumferentially around the winding disk 23. The movement of the moving block 221 will drive the vertical shaft 1 222 to move synchronously. During the synchronous movement of the vertical shaft 1 222, it will drive the tape 1 24 to synchronously wrap around the exposed part of the cable.

[0086] (4): During the upward movement of the lifting frame 31, the cable management cylinder 32 is synchronously driven to move upward. The cable management cylinder 32 rotates synchronously during the upward movement. When the cable management cylinder 32 moves up to the cable connection section, the cable management cylinder 32 can drive the cable connection section to rotate around the connection point of the two cables during the upward movement, and make the cable connection section close to the upper cable. At this time, the cable management cylinder 32 is driven to rotate by an external driving force. During the rotation of the cable management cylinder 32, it cooperates with the connecting block 323 to wrap the cable connection section around the upper cable.

[0087] (5): During the rotation of the cable management cylinder 32, the fixed protrusion 321 and the vertical shaft 322 cooperate with each other to drive the tape 33 to rotate synchronously in the circumferential direction, and the tape 33 wraps around the cable. When the tape 33 moves to the cable connection, the tape 33 continues to wrap around and wraps around the rotated cable connection section, so that the cable connection section is further fixed on the cable.

[0088] (6): When the lifting frame 31 drives the lifting frame 311 to move upward, the traction rope 312 is released from the rotating roller 318 and the line is released. During the release process of the traction rope 312, the vertical connecting frame 319 and the reversing shaft 310 cooperate with each other to reverse the traction rope 312, so that the horizontally moving traction rope 312 moves along the length direction of the cable after reversing. At this time, the traction rope 312 is close to the cable.

[0089] The existing pneumatic gripper drives the adhesive tape three 316 to adhere to the cable, and the electric slider 314 rotates around the cable for a certain number of circles. At this time, the electric slider 314 cooperates with the vertical axis three 315 to drive the adhesive tape three 316 to further wrap the cable against the traction rope 312.
