Abstract
Description
Technical Field
[0001] This utility model relates to the field of stranded wire welding technology, and more specifically to a corrective wiring assembly for a stranded wire welding robot with position compensation point. Background Technology
[0002] In modern industrial automated production, welding technology is widely used in new energy vehicles, power equipment, electronic equipment, and other fields, with the welding of stranded wire being one of the key processes. With the development of intelligent manufacturing, welding robots with position compensation functions are becoming increasingly common. These robots adjust the welding path in real time through sensors and algorithms, effectively addressing workpiece tolerances or assembly deviations and improving welding accuracy. However, the existing wiring components do not have the function of position compensation, which may cause slight errors in the gripping position of the robot end effector. This can lead to a shift in the relative position between the stranded wire end to be welded and the welding electrode, resulting in poor welding and uneven weld points, which affects the processing stability of the device. Therefore, to address the aforementioned issues, there is an urgent need for innovative design based on the existing wiring components. Utility Model Content
[0003] The purpose of this invention is to provide a corrective wiring assembly for a stranded wire welding robot with position compensation, in order to solve the problem mentioned in the background art that the current wiring assemblies do not have the function of position compensation, which may cause slight errors in the gripping position of the robot's end effector, resulting in the relative position of the stranded wire end to be welded and the welding electrode to shift, causing incomplete welding and uneven weld points, thus affecting the processing stability of the device.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a corrective wiring assembly for a stranded wire welding robot with position compensation, comprising: a support base, and a sleeve disposed on the upper left side of the support base, wherein a second support frame is disposed on the right side of the sleeve, and a clamping claw body is disposed inside the second support frame; Also includes: A mobile battery is installed inside a support base, and a cover plate is provided on the right side of the mobile battery. A displacement sensor is provided on the right side of the support base, and a first drive motor is installed in the middle of the support base. A first drive rod is connected to the right side of the first drive motor, and a connecting block is connected to the middle of the first drive rod. A guide strip is provided on the outside of the connecting block. A flexible clamping assembly is provided inside the second support frame. A first support frame is installed inside the sleeve, and a first guide ridge is attached to the inner side of the first support frame. A second guide ridge is installed on the left side of the first support frame, and a pressure plate is provided on the right side of the first support frame. A drive frame is provided on the outer side of the pressure plate, and a guide block is connected to the middle of the drive frame. A return spring is provided on the drive frame.
[0005] In one possible implementation, the first support frame is engaged with the sleeve, and the first guide ridge is set at an equal angle inside the first support frame.
[0006] In one possible implementation, the drive frame is slidably connected to the guide block, and the return springs are evenly spaced on the outer side of the drive frame.
[0007] In one possible implementation, the first drive rod is threadedly connected to the connecting block, and the connecting block is slidably connected to the guide bar.
[0008] In one possible implementation, the longitudinal section of the guide strip is a "T"-shaped structure, and the guide strip is symmetrically arranged about the central axis of the connecting block.
[0009] In one possible implementation, the flexible clamping assembly includes a second drive motor installed inside the second support frame, and a second drive rod is connected to the upper side of the second drive motor. A guide rod is connected to the front end of the clamping claw body, and a buffer pad is attached to the inner side of the clamping claw body. The second drive rod is threadedly connected to the gripper body, and the threads at the upper and lower ends of the second drive rod are opposite to each other.
[0010] In one possible implementation, the gripper body is slidably connected to the guide rod, and the gripper body and the buffer pad are arranged symmetrically about the central axis of the second support frame.
[0011] Compared with the prior art, the present invention has at least the following beneficial effects: The corrective wiring assembly for the stranded wire welding robot with position compensation point, by setting a position adjustment module inside the device, enables the device to correct the deviation when the robot grasps the wire in real time, ensuring that the end of the stranded wire to be welded is aligned with the welding electrode, avoiding false welding or weld point misalignment, and improving the processing stability of the device. At the same time, the design of clamping claws with a buffer layer inside the device ensures that the device takes into account both clamping force and wire protection during the processing of stranded wire, preventing displacement during welding, adapting to stranded wires of different diameters, and having a better performance, as shown in the following details. 1. The first support frame, in conjunction with the first and second guide ridges, guides the incoming stranded wire, so that the loose strands are regrouped and compacted by the first and second guide ridges. This ensures that stranded wires that have become loose or scattered due to vibration or external force are regrouped, preventing the end strands from scattering and causing uneven contact between the strands during welding, which would affect the conductivity and ensure the subsequent processing of the stranded wire. 2. The second drive motor, in conjunction with the second drive rod, pushes the clamping claw body and the buffer pad to move relative to each other along the guide rod inside the second support frame. This allows the clamping claw body, moving inward, to clamp and fix the protruding stranded wire in conjunction with the buffer pad. At the same time, the buffer pad attached to the inner side of the clamping claw body can effectively increase the friction between the clamping claw body and the stranded wire, while avoiding damage to the stranded wire caused by rigid clamping. This ensures that the clamping is stable and does not damage the wire. At this time, due to the adjustability of the clamping claw body, the device can still maintain an effective clamping effect when facing stranded wires of different diameters, thus improving the clamping stability of the device. 3. The displacement sensor, in conjunction with the first drive motor, drives the first drive rod to rotate inside the support base. This causes the first drive rod to push the connecting block and the second support frame to move left and right along the guide strip inside the support base. At this time, the second support frame, which moves to the right, causes the stranded wire clamped inside it to move to the right on the upper side of the support base, ensuring that the end of the stranded wire to be welded is strictly aligned with the welding electrode, thus avoiding incomplete welding or weld point misalignment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Please see Figures 1-6 The present invention provides the following technical solution: A corrective wiring assembly for a stranded wire welding robot with position compensation includes: a support base 1, a preset hole 2, a movable battery 3, a cover plate 4, a sleeve 5, a first support frame 6, a first guide ridge 7, a second guide ridge 8, a clamping plate 9, a drive frame 10, a guide block 11, a reset spring 12, a displacement sensor 13, a first drive motor 14, a first drive rod 15, a connecting block 16, a guide strip 17, a second support frame 18, a second drive motor 19, a second drive rod 20, a gripper body 21, a guide rod 22, and a buffer pad 23. Specifically, such as Figure 2 , Figure 4 and Figure 5As shown, before using the device, the support base 1 is placed in a designated location, and the locking bolt is passed through the preset hole 2 to limit the support base 1. At this time, the mobile battery 3 is installed inside the support base 1, and the cover plate 4 is installed on the left side of the mobile battery 3. At this time, due to the snap-fit connection structure between the first support frame 6 and the sleeve 5, the operator can easily install the first support frame 6, the first guide protrusion 7, and the second guide protrusion 8 inside the sleeve 5. Then, the robot picks up the stranded wire and inserts it into the sleeve 5. The first guide protrusion 7 and the second guide protrusion 8 inside the first support frame 6 guide the entering stranded wire. At this time, the loose strands are gathered and compacted by the first guide protrusion 7 and the second guide protrusion 8 to ensure that the wire is properly secured due to vibration. The stranded wires that have become loose or scattered due to external force are re-gathered. At the same time, the stranded wires that continue to move to the right reach the inside of the clamping plate 9. At this time, the clamping plate 9 set inside the sleeve 5 applies radial pressure to the stranded wires passing through it under the influence of the return spring 12 and the drive frame 10, preventing the strands from spreading out again inside the sleeve 5. Due to the sliding connection structure between the guide block 11 and the drive frame 10, the clamping plate 9 and the drive frame 10 are guided and limited by the guide block 11 during the process of applying pressure inward, so as to avoid the clamping plate 9 and the drive frame 10 from shifting their positions during the movement. This completes the correction and gathering of the stranded wires, avoids the strands at the ends from spreading out, and prevents the strands from not being able to make uniform contact during welding, which would affect the conductivity and ensure the subsequent processing of the stranded wires. Simultaneously, after completing the re-gathering of the stranded wires, the second drive motor 19 installed inside the second support frame 18 is activated. This causes the second drive motor 19 to drive the second drive rod 20 connected to its upper side to rotate inside the second support frame 18. Due to the threaded connection between the second drive rod 20 and the clamping claw body 21, the second drive rod 20 can effectively push the clamping claw body 21 to move up and down inside the second support frame 18 during rotation. At this time, because the upper and lower ends of the second drive rod 20 have opposite threaded structures, the second drive rod 20 can effectively push the clamping claw body 21 to move relative to each other inside the second support frame 18 during rotation. The sliding connection between the clamping claw body 21 and the guide rod 22 results in the clamping claw body 21 being guided and limited by the guide rod 22 during relative movement, preventing the clamping claw body 21 and the buffer pad 23 from shifting outwards during movement. At this time, the clamping claw body 21 moving inwards, together with the buffer pad 23, clamps and fixes the protruding stranded wire. At the same time, the buffer pad 23 attached to the inner side of the clamping claw body 21 can effectively increase the friction between the clamping claw body 21 and the stranded wire, while avoiding the stranded wire being crushed due to rigid clamping, ensuring that the clamping is stable and does not damage the wire. At this time, due to the adjustability of the clamping claw body 21, the device can still maintain the effective clamping effect when facing stranded wires of different diameters, improving the clamping stability of the device. Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, during the use of the device, the displacement sensor 13 set on the right side of the support base 1 monitors the theoretical position difference between the stranded wire end to be welded and the welding electrode in real time, and drives the first drive motor 14 set in the middle of the support base 1 to work based on the obtained data results. At this time, the first drive motor 14 drives the first drive rod 15 connected to its right side to rotate inside the support base 1. Due to the threaded connection structure between the first drive rod 15 and the connecting block 16, the first drive rod 15 can effectively push the connecting block 16 to move left and right inside the support base 1 during the rotation process. At this time, due to the sliding connection structure between the connecting block 16 and the guide strip 17, the connecting block 16 and the second support frame 18 are guided and limited by the guide strip 17 during the left and right movement, so as to avoid the second support frame 18 and the connecting block 16 from tilting at an angle during the left and right movement. At this time, the second support frame 18, which moves to the right, drives the stranded wire clamped inside to move to the right side on the upper side of the support base 1, ensuring that the stranded wire end to be welded is strictly aligned with the welding electrode, avoiding poor welding or weld point misalignment.
