Description

Technical Field

[0001] This application relates to the field of cable processing technology, and in particular to an automatic splicing system for aluminum-copper wires. Background Technology

[0002] When the aluminum and copper wires in the wire reel inside the cable stranding machine are used up during cable processing, it is necessary to use other hoisting equipment to replace the old wire reel. The new aluminum and copper wires on the new wire reel need to be connected to the old aluminum and copper wires on the wire stranding machine.

[0003] To distinguish between the new aluminum-copper wire on the new wire reel and the old aluminum-copper wire on the frame stranding machine, the first line represents the old aluminum-copper wire and the second line represents the new aluminum-copper wire.

[0004] In existing technologies, workers often complete steps such as cutting the first wire on the wire stranding machine, finding the second wire end on the new wire reel, and splicing the first and second wires. Welding tools are often required to assist in the splicing, and finding the second wire end on the new wire reel relies entirely on the worker's eyesight. This prolongs the downtime of the wire stranding machine, extends the cable processing time, and reduces the efficiency of cable processing. Summary of the Invention

[0005] To improve the efficiency of cable processing, this application provides an automatic splicing system for aluminum-copper wires.

[0006] The automatic splicing system for aluminum and copper wires provided in this application adopts the following technical solution: An automatic aluminum-copper wire splicing system includes a moving stage, a moving mechanism below the moving stage for driving its movement, and a body above the moving stage. The body is equipped with two gripping arms for holding a first or second wire, a cutting component for cutting the first or second wire, a vision camera for capturing the end of the second wire, a solder resist for welding the first and second wires, a grinding component for removing welding burrs, and a drive assembly for rotating a new wire spool. Both sides of the solder resist are equipped with traction mechanisms for conveying the first or second wire. During splicing, the cutting component first cuts the first wire, and the vision camera captures the end of the second wire on the new wire spool. Then, the traction mechanisms convey the first and second wires to the solder resist station. The solder resist welds the first and second wires, forming an integrated wire. The grinding component removes welding burrs from the integrated wire, and the drive assembly drives the wire spool to rotate, causing the integrated wire to rewind onto the spool.

[0007] By adopting the above technical solution, the moving platform moves the machine body to the designated position through the moving mechanism. Then, the gripping arm grabs the first wire and cuts it with the cutting component, temporarily fixing the first wire to the frame winding machine. After replacing the wire spool, the vision camera captures the end of the second wire on the new wire spool, and the gripping arm clamps the end of the second wire. First, the excess second wire material is cut off at the cutting component. Then, the ends of the first and second wires are ground by the grinding component. The first and second wires are then welded together by the solder resist component to form an integrated wire. The welding burrs of the integrated wire are then ground off by the grinding component. Finally, the drive component drives the new wire spool to rotate to wind up the integrated wire until it is straight, thus achieving the effect of connecting the first and second wires. Using a clamping arm as the transfer component for the first and second wires, the system controls the movement of the first and second wires in space. This allows the first and second wires to undergo multiple processes, including cutting, grinding, welding, and further grinding of welding burrs. Finally, a drive assembly reverses the rotation of the new wire spool to tighten and integrate the wires. The entire process is automated and requires no manual intervention, reducing downtime of the wire stranding machine, shortening cable processing time, and improving cable processing efficiency.

[0008] Optionally, the moving mechanism includes a lateral moving component and a longitudinal moving component that drives the machine body to move longitudinally. The lateral moving component includes a lateral rail, rollers, a lateral motor, and limiting wheels. The lateral rail is set on the ground. Four rollers are provided and rotatably connected below the moving platform. The rollers roll on the lateral rail. A drive shaft is connected between two of the rollers. The lateral motor is installed inside the moving platform and is connected to the drive shaft through a sprocket and chain assembly. Four limiting wheels are horizontally rotatably connected below the moving platform, and two of them are arranged in a group. One group of limiting wheels abuts against the side wall of the lateral rail. The longitudinal moving component is located between the machine body and the moving platform.

[0009] By adopting the above technical solution, when moving, the horizontal motor is started to rotate the rollers, and the limiting wheel is used to abut against the side wall of the horizontal rail, so that the moving platform can move on the horizontal rail. In conjunction with the longitudinal moving component to adjust the position of the machine body, the moving machine body can be moved.

[0010] Optionally, the longitudinal movement assembly includes a longitudinal motor, a longitudinal lead screw, a longitudinal rail, and a nut block. The longitudinal rail is connected to the top wall of the moving platform and is perpendicular to the transverse rail. The machine body is slidably fitted on the longitudinal rail. The longitudinal lead screw is rotatably connected to the moving platform and is parallel to the longitudinal rail. The longitudinal motor is mounted on the moving platform and connected to the longitudinal lead screw. The nut block is connected to the bottom wall of the machine body and is threadedly fitted to the longitudinal lead screw.

[0011] By adopting the above technical solution, when the machine body is moved longitudinally, the longitudinal motor is started, causing the longitudinal lead screw to rotate. Through the restriction of the longitudinal rail and the longitudinal lead screw, the nut block is moved, thereby achieving the effect of moving the machine body.

[0012] Optionally, the traction mechanism includes a first traction component and a second traction component for traction of the aluminum-copper wire end to the position of the resist welding component. The first traction component includes a first frame, a first traction motor, and a first traction wheel. Two first frames are provided and are perpendicular to each other. A first fixing block and a first pressure block are provided in the first frame. A first pressure member is provided on the first frame to drive the first pressure block to move. Several first traction wheels are rotatably connected to the first fixing block and similarly provided on the first pressure block. The two sets of first traction wheels are staggered. The first traction motor is mounted on the first fixing block and connected to one of the first traction wheels. The remaining first traction wheels are driven by a gear set. The second traction component is provided on one side of the resist welding component and above the first frame. The feed end of the first frame is provided with a proximity sensor for sensing the first or second wire. The proximity sensor is electrically connected to the internal control system of the machine body.

[0013] By employing the above technical solution, the clamping arm cannot precisely control the position of the first wire end when gripping the first wire. Therefore, a structure capable of predicting the position of the aluminum-copper wire end needs to be designed before grinding and welding. The first pressure block is moved beforehand by a first pressure-applying component, bringing the two sets of first traction wheels closer together. During traction, the clamping arm grips the first wire, and the wire end reaches the proximity sensor's sensing end. Calculations begin from this point. Then, the first traction motor is activated, causing the first traction wheels to rotate. The first wire moves under the pressure and friction of the first traction wheels until the wire end contacts the grinding component. At this point, the wire end position can be calculated. The clamping arm then grips the first wire at a designated position and brings the wire end close to the second traction component. The second traction component moves the ground first wire to the welding resist component, achieving calculable and precise delivery. The second wire is processed in the same way. The calculation begins when the wire approaches the sensor. The first wire is pulled by the first traction wheel to the grinding part for grinding. Then, the clamping arm clamps the first wire at a fixed position. The position where the first wire end enters the second traction component can also be calculated. Finally, the distance the first wire moves into the solder resist component through the second traction component can also be calculated, thus achieving the effect of accurately pulling the aluminum copper wire end.

[0014] Optionally, the machine body is provided with a guiding component, which includes a first tube and a second tube. The first tube is disposed between the first frame and the grinding component. The diameter of the inlet end of the first tube is larger than the diameter of the outlet end. The machine body is provided with an adjusting component for adjusting the position of the first tube. The second tube is connected to the machine body and is located between the second traction component and the welding resist component. A notch is opened on the side wall of the second tube. The diameter of the inlet end of the second tube is larger than the diameter of the outlet end.

[0015] By adopting the above technical solution, the first wire is moved by the traction mechanism. However, after the first wire end detaches from the traction mechanism, it is easy for the first wire end to deviate from the predetermined route, making it impossible for the first wire end to accurately reach the designated work station. The guidance of the first tube ensures that the first wire end can accurately reach the work station. At the same time, the diameter of the discharge end is reduced, which easily restricts the aluminum and copper wires, allowing the first wire end to be better ground and welded. The same applies to the second wire.

[0016] Optionally, the adjustment assembly includes an adjustment frame, a moving block, a fixed post, a pressure spring, and an adjustment nut. The adjustment frame is U-shaped and connected to the machine body, located between the first frame and the grinding component. A limiting strip is connected to the moving block, which slides within the adjustment frame via the limiting strip. The first tube is mounted on the moving block. A sealing block is rotatably connected to the opening of the adjustment frame. A locking assembly for locking the sealing block is provided on the adjustment frame. A clearance groove is formed on the sealing block. The fixed post is connected to the moving block and passes through the clearance groove. The pressure spring is sleeved on the fixed post and located between the moving block and the sealing block. The adjustment nut is threaded onto the fixed post and abuts against the side wall of the sealing block away from the pressure spring.

[0017] By adopting the above technical solution, when adjusting the position of the first tube, rotating the adjusting nut causes the moving block to move through the sliding cooperation between the limiting strip and the adjusting frame. At the same time, the pressure spring applies pressure to the moving block, making the moving block stable in the designated position, thereby achieving the effect of adjusting the position of the first tube.

[0018] Optionally, the locking assembly includes a locking block, a sealing rod, and a limiting plate. The sealing block has a limiting groove, and the locking block is connected to a T-shaped block. The locking block slides on the adjusting frame through the T-shaped block and matches the limiting groove in shape. One end of the sealing rod is rotatably connected to the end of the sealing block. The locking block is located between the sealing block and the sealing rod. The limiting plate is connected to the adjusting frame. A limiting protrusion is connected to the side wall of the limiting plate near the sealing rod. When locked, the other end of the sealing rod is located between the limiting protrusion and the adjusting frame.

[0019] By adopting the above technical solution, when locking the sealing block, the sealing block is rotated, and then the locking block is moved into the limiting groove. The sealing rod is swung, and the locking rod abuts against the limiting protrusion, causing the limiting plate to deform until the locking rod fits against the adjusting frame, thereby limiting the swing of the sealing rod. The sealing rod limits the movement of the locking block, and the locking block limits the rotation of the sealing block, thus achieving the effect of limiting the sealing block.

[0020] Optionally, the adjustment frame is provided with an angle limiting component, which includes an adjusting ball block, a hydraulic housing, and a pressure bolt. The adjusting ball block is ball-connected to the moving block, and the first pipe passes through the adjusting ball block. The hydraulic housing is embedded between the moving block and the fixed column. One end of the hydraulic housing is provided with a pressure wall, and the other end is provided with a piston. The pressure bolt is threaded into the other end of the hydraulic housing and is rotatably connected to the piston. The diameter of the screw head of the pressure bolt is smaller than the diameter of the fixed column. The hydraulic housing is filled with hydraulic oil. When limited, the pressure wall deforms and abuts against the arc surface of the adjusting ball block.

[0021] By adopting the above technical solution, in order to minimize the space occupied by the machine body, the internal components will inevitably deviate from their predetermined positions in terms of layout, such as the position of the first traction component. Therefore, in order to ensure that the aluminum and copper wires can accurately reach the work station, it is necessary to adjust the angle of the first tube. During adjustment, the angle of the first tube is swung to ensure that the feed end of the first tube is aligned with the first traction tube and the discharge end is aligned with the grinding part. Then, the pressure bolt is rotated to move the piston, which drives the pressure wall to deform through hydraulic oil. The pressure wall presses against the adjusting ball block to limit the rotation of the adjusting ball block, thereby achieving the effect of adjusting the angle of the first traction tube.

[0022] Optionally, the drive assembly includes a drive cylinder, a drive motor, a moving frame, and drive wheels. The drive cylinder is mounted on the machine body, the moving frame is connected to the output shaft of the drive cylinder, the drive wheels are rotatably connected to the moving frame, and two of them are provided. The drive motor is mounted on the moving frame and is connected to the drive wheels through a sprocket and chain assembly.

[0023] By adopting the above technical solution, when the new wire spool is reverse-winding, the drive electric cylinder is activated to move the moving frame, which in turn moves the two drive wheels until they contact the surface of the new wire spool. The drive motor is then activated to rotate the two drive wheels. Through friction, the new wire spool is rotated, thus achieving the effect of rewinding the new wire spool into a production line.

[0024] Optionally, a pressure application assembly is installed on the gripping arm for gripping the second wire. The pressure application assembly includes a pressure sensor, a wire pressing roller, an adjusting cylinder, and guide wheels. The output end of the gripping arm is connected to a rotating frame, and a connecting plate is provided on the rotating frame. The adjusting cylinder is connected between the rotating frame and the connecting plate. Two guide wheels are provided, one of which is rotatably connected to the connecting plate and the other is rotatably connected to the rotating frame. A pressure frame is slidably fitted on the connecting plate, and a return spring is installed on the pressure frame. The wire pressing roller is rotatably connected to the pressure frame. The pressure sensor is installed on the mounting plate, with its detection end facing the end of the pressure frame.

[0025] By adopting the above technical solution, if the new wire spool is directly rewound after the integrated wire is welded and polished, the drooping integrated wire may come into contact with other components, causing the integrated wire to fail to rewind smoothly and resulting in damage. By using a clamping arm to guide the integrated wire between two guide wheels, activating the adjusting cylinder moves the connecting plate, which in turn moves the guide wheels, causing them to clamp the aluminum-copper wire. Through the cooperation of the pressure roller and the return spring, the aluminum-copper wire is pressed against the surface of the new wire spool, ensuring that the aluminum-copper wire is effectively wound up when the new wire spool rewinds.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The moving table moves the machine body to the designated position via the moving mechanism. Then, the gripping arm grabs the first wire and cuts it with the cutting component, temporarily fixing the first wire to the frame winding machine. After replacing the wire spool, the vision camera captures the end of the second wire on the new wire spool, and the gripping arm clamps the end of the second wire. First, the excess second wire is cut off at the cutting component. Then, the ends of the first and second wires are ground by the grinding component. The first and second wires are then welded together by the solder resist component to form an integrated wire. The welding burrs of the integrated wire are then ground off by the grinding component. Finally, the drive component drives the new wire spool to rotate to wind up the integrated wire until it is straight, thus achieving the effect of connecting the first and second wires. Using the clamping arm as the transfer component for the first and second wires, the system controls the movement of the first and second wires in space, allowing them to undergo multiple processes such as cutting, grinding, welding, and further grinding of welding burrs. Finally, the drive component reverses the rotation of the new wire spool to tighten and integrate the wires. The entire process is automated and requires no manual intervention, which reduces the downtime of the wire stranding machine, shortens the cable processing time, and improves the efficiency of cable processing. 2. The first pressure block is moved by the first pressure-applying component beforehand, bringing the two sets of first traction wheels closer together. During traction, the clamping arm clamps the first wire, and the wire end reaches the sensing end of the proximity sensor. Calculation begins from this point. Then, the first traction motor is started, causing the first traction wheel to rotate. The first wire moves under the pressure and friction of the first traction wheel until the wire end contacts the grinding part. At this point, the wire end position can be calculated. The clamping arm then clamps the first wire at a designated position and brings the wire end close to the second traction component. The second traction component moves the ground first wire to the solder resist part, achieving calculable and precise delivery. The second wire is processed in the same way. Calculation begins when the wire passes the proximity sensor. The first wire is pulled by the first traction wheel to the grinding part for grinding. The clamping arm then clamps the first wire at a fixed position. Thus, the position where the wire end enters the second traction component can also be calculated. Finally, the distance the first wire moves into the solder resist part through the second traction component can also be calculated, achieving precise traction of aluminum and copper wire ends. 3. When locking the sealing block, rotate the sealing block, then move the locking block into the limiting groove, swing the sealing rod, the locking rod abuts against the limiting protrusion, the limiting plate deforms until the locking rod fits against the adjusting frame to limit the swing of the sealing rod, the sealing rod limits the movement of the locking block, and the locking block limits the rotation of the sealing block, thus achieving the effect of limiting the sealing block; 4. During adjustment, swing the angle of the first tube to ensure that the feed end of the first tube is aligned with the first traction tube and the discharge end is aligned with the grinding part. Then rotate the pressure bolt to move the piston. The hydraulic oil drives the pressure wall to deform, and the pressure wall presses against the adjusting ball block to limit the rotation of the adjusting ball block, thus achieving the effect of adjusting the angle of the first traction tube.

The sealing block 511 is rotated, and the fixing post 53 passes through the clearance groove, pushing the locking block 61 into the limiting groove 5111. The sealing rod 62 is flipped, blocking the limiting groove 5111. The sealing rod 62 abuts against the limiting protrusion 631, and the limiting plate 63 deforms until the sealing rod 62 abuts against the adjusting frame 51, thus limiting the sealing rod 62 between the limiting protrusion 631 and the adjusting frame 51. Then, the angle of the first tube 41 is adjusted to ensure that the feed end of the first tube 41 is aligned with the first traction wheel 313 and the discharge end is aligned with the grinding part 13. Then, the pressure bolt 73 is rotated, and the piston 731 moves, causing the pressure wall to deform through hydraulic oil. The pressure wall then adheres to the adjusting ball block 71 to limit the first tube 41, thus completing the installation of the first tube 41.

[0051] Reference Figure 2 and Figure 3 The second tube 42 is fixedly connected to the machine body 11 and is located between the second frame and the weld resist 14. The diameter of the inlet end of the second tube 42 is larger than the diameter of the outlet end. A notch is provided on the side of the second tube 42 away from the machine body 11.

[0052] Reference Figure 9 The machine body 11 is equipped with a drive assembly 8, which includes a drive cylinder 81, a drive motor 82, a moving frame 83, and drive wheels 84. The drive cylinder 81 is mounted on the machine body 11, and the moving frame 83 is fixedly connected to the output shaft of the drive cylinder 81. Two drive wheels 84 are provided, both of which are rotatably connected to the moving frame 83. The drive motor 82 is mounted on the moving frame 83 and is connected to the drive wheels 84 through a sprocket and chain assembly.

[0053] When the new wire spool 02 is rotated, the drive cylinder 81 is started, which moves the moving frame 83 and drives the drive wheel 84 to move until it presses against the surface of the new wire spool 02. Then the drive motor 82 is started, which makes the drive wheel 84 rotate. Through friction, the new wire spool 02 is rotated.

[0054] Reference Figure 9 A connecting frame is fixedly connected to the body 11. A vision camera 15 and an illumination ring 151 are mounted on the connecting frame. The illumination ring 151 is used to provide an illumination environment for the vision camera 15. Gripping arms 16 are provided on both sides of the body 11. The gripping arms 16 are robotic arms, and the ends of the robotic arms are provided with grippers 161 for gripping the second line.

[0055] Reference Figure 2 and Figure 10The clamping arm 16, used to grip the end of the new wire spool 02, has a rotating frame at its output end. A gripper 161 is mounted on one end of the rotating frame, and a pressure application assembly 9 is located on the other end. The pressure application assembly 9 includes a pressure sensor 91, a pressure roller 92, an adjusting cylinder 93, and guide wheels 94. A connecting plate is mounted on the adjusting cylinder 93, and the output shaft of the adjusting cylinder 93 is fixedly connected to the rotating frame. Two guide wheels 94 are provided, one mounted on the rotating frame and the other on the connecting plate. A pressure frame is slidably fitted on the connecting plate, and a return spring is mounted on the pressure frame. The pressure sensor 91 is mounted on the connecting plate, with its sensing end aligned with the end of the pressure frame. The pressure roller 92 is mounted on the pressure frame.

[0056] Reference Figure 1 and Figure 11 The frame winding machine 01 is located on one side of the moving platform 1. The frame winding machine 01 is equipped with several wire spools 02 and clamping parts 011, with each clamping part 011 corresponding to one of the wire spools 02.

[0057] The implementation principle of an automatic aluminum-copper wire splicing system according to an embodiment of this application is as follows: When the first wire on the old wire spool 02 is used up, the horizontal motor 213 is started, causing the roller 212 to roll on the horizontal rail 211, driving the moving table 1 to move to the designated position. The vertical motor 221 is started, causing the vertical lead screw 222 to rotate, driving the nut block 224 to move until the machine body 11 moves to the designated position. Then, the clamping arm 16 clamps the first wire and cuts it with the cutting piece 12, installing the end of the first wire on the clamping part 011 of the frame stranding machine 01. Then, the old wire spool 02 is removed by the hoisting machine, and the new wire spool 02 is installed on the frame stranding machine 01. The vision camera 15 scans the end of the second wire on the new wire spool 02, the clamping arm 16 clamps the end of the second wire, and the cutting piece 12 removes the excess second wire material. The clamping arm 16 moves the ends of the first and second wires to the corresponding proximity sensors 3113. The wire is pulled by the first traction wheel 313, polished by the polishing part 13, then moves in the opposite direction and is clamped at a designated position by the clamping arm 16 and conveyed to the second traction wheel 322. The second traction wheel 322 pulls the wire until it approaches the welding resist part 14 for welding. The first wire and the second wire form an integrated wire. Then the clamping arm 16 clamps the integrated wire, the polishing part 13 polishes the burrs of the integrated wire, the two guide wheels 94 clamp it, and the pressure roller 92 applies pressure to press the integrated wire against the surface of the new wire spool 02. The drive cylinder 81 is started, and the moving frame 83 moves until the drive wheel 84 presses against the surface of the new wire spool 02. The drive motor 82 is started, which drives the drive wheel 84 to rotate. The new wire spool 02 rotates to tighten the integrated wire, realizing the effect of automatic splicing of the first wire and the second wire.

[0058] Using the clamping arm 16 as the transfer component for the first and second wires, the movement of the first and second wires in space is controlled, allowing the first and second wires to undergo multiple processes such as cutting, grinding, splicing with weld resistance, and grinding off welding burrs. Finally, the drive component 8 drives the new wire spool 02 to rotate in reverse to tighten and integrate the wires. The entire process is automated and requires no manual intervention, which shortens the downtime of the wire stranding machine, reduces the cable processing time, and improves the efficiency of cable processing.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
