Description

Technical Field

[0001] This invention relates to the technical field of robot wiring harness fixing. More specifically, this invention relates to an automated robot wiring harness fixing device. Background Technology

[0002] During robot installation, cables and air pipes need to be laid on its outside. To avoid interference between the cables and air pipes during robot operation, existing technology will insert the cables and air pipes into the inside of a corrugated pipe and then fix the corrugated pipe to the outside of the robot, thus protecting the cables and air pipes through the corrugated pipe.

[0003] Because the corrugated pipe is relatively long and its inner side is uneven, when the cable and air tube are manually pushed out of the corrugated pipe, the head of the cable and air tube will droop and contact the groove on the inner side of the corrugated pipe, causing it to get stuck. At this time, the operator needs to frequently adjust the position of the cable and air tube in order to push them out smoothly. The operation is cumbersome and inefficient.

[0004] In summary, this application proposes an automated robot wire harness fixing device to improve the aforementioned technical problems. Summary of the Invention

[0005] To overcome the drawback that during the manual threading of cables and air tubes through corrugated pipes, the ends of the cables and air tubes droop and get stuck in the grooves inside the corrugated pipes, requiring frequent manual adjustments to ensure successful threading, this invention provides an automated robot wire harness fixing device.

[0006] Technical solution:

[0007] An automated robot wiring harness fixing device includes a corrugated tube and a first ring; the first ring is disposed on the side of the corrugated tube; it also includes a second ring, a threading block, ball bearings, and a fixing component; the second ring is connected to the inner side of the first ring; the threading block is fixedly connected to the inner side of the second ring; the threading block has several first holes; the threading block has several narrow grooves, which communicate with the corresponding first holes, and all the narrow grooves are interconnected; the threading block is elastic; several ball bearings are rotatably connected to the outer ring surface of the first ring; the fixing component is connected to the corrugated tube, and the fixing component is used to fix the end of the corrugated tube.

[0008] To further explain, in the above-mentioned automated robot harness fixing device, the fixing component includes a base and a fixing block 1; the base is provided at the end of the corrugated pipe; the fixing block 1 is fixedly connected to the base, and the fixing block 1 is in contact with the corrugated pipe.

[0009] To further explain, the aforementioned automated robot harness fixing device also includes a second fixing block and a linkage unit; several second fixing blocks are slidably connected on the first ring; the linkage unit is connected to the first ring, and the linkage unit is used to drive the second fixing blocks to perform linear motion.

[0010] To further explain, in the above-mentioned automated robot harness fixing device, the linkage unit includes a spring and a linkage block; the first ring and the second ring are rotatably connected; several springs are fixedly connected to each second fixing block, and the springs are fixedly connected to the first ring; several linkage blocks are fixedly connected to the first ring, and the linkage blocks are in contact with the corresponding second fixing blocks; the contact surfaces of the second fixing blocks and the linkage blocks are all set as inclined surfaces.

[0011] To further explain, the aforementioned automated robot harness fixing device also includes auxiliary components, which include a first protrusion and a second protrusion; the first protrusion is fixedly attached to the first ring; and the second protrusion is fixedly attached to the second ring.

[0012] To further explain, the aforementioned automated robot harness fixing device also includes a long rod; the long rod is threaded through the middle of the wire-threading block; and the middle of the long rod is configured as a truncated cone.

[0013] To further explain, in the aforementioned automated robot harness fixing device, flanges are provided at both ends of the long rod.

[0014] To further explain, the aforementioned automated robot harness fixing device also includes protective blocks; several protective blocks are fixed to the end of the long rod.

[0015] To further explain, in the aforementioned automated robot harness fixing device, one edge of the ring has a chamfer.

[0016] To further explain, in the aforementioned automated robot wire harness fixing device, the surface of the ball bearing is set to a smooth surface.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By using the combination of ring one, ring two, threading block and ball bearings, cables and air tubes can be quickly passed through the inside of the corrugated pipe without the problem of the cable and air tube ends getting stuck in the groove inside the corrugated pipe. This greatly improves work efficiency and the convenience of manual operation. At the same time, during the operation of the robot, the threading block can be equivalent to the wire divider in the existing technology, which can limit the air tube of each cable and prevent entanglement.

[0019] Second, by using a fixed block two instead of ball bearings to clamp the bellows, the problem of low stability caused by the bellows being squeezed only on the rolling ball bearings is avoided. In addition, the fixed block two is stuck in the groove on the inside of the bellows, which can limit the bellows in the axial direction and further increase the stability.

[0020] Third, during the threading process, the long rod applies pressure to the threading block, causing the threading block to deform and compress the cable and air tube. The greater the tension and resistance during threading, the greater the pressure of the long rod on the threading block, and the greater the compressive force of the threading block on the cable and air tube, effectively preventing the cable and air tube from falling off. When connecting the wires, the operator only needs to push the long rod to the right inside the threading block to reduce the pressure of the threading block on the cable and air tube, making it easy for the operator to pull the cable and air tube to perform the connection operation.

[0021] Fourth, when the ring and its parts encounter great resistance during the threading process, the protective block can push the ring and its parts to the left. At this time, the long rod and the threading block no longer move relative to each other, effectively avoiding the problem of the long rod falling off. Attached Figure Description

Detailed Implementation

[0029] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0030] Example 1: An automated robot wire harness fixing device, such as Figures 1-4 As shown, it includes a corrugated pipe 1 and a circular ring 2; the corrugated pipe 1 has a circular ring 2 on its side, and the circular ring 2 is made of plastic; it also includes a circular ring 3, a threading block 4, ball bearings 5, and a fixing component; the circular ring 3 is connected to the inner side of the circular ring 2; the threading block 4 is fixed to the inner side of the circular ring 3; the threading block 4 has five circular holes 91; the threading block 4 has five narrow grooves 92, which are connected to the corresponding circular holes 91, and all the narrow grooves 92 are interconnected; the threading block 4 is elastic; several ball bearings 5 ​​are rotatably connected to the outer ring surface of the circular ring 2; the corrugated pipe 1 is connected to the fixing component.

[0031] The fixing component includes a base 201 and a fixing block 202; the base 201 is provided at the end of the corrugated pipe 1, and the base 201 is made of plastic; the fixing block 202 is bolted to the base 201, and the fixing block 202 contacts the corrugated pipe 1. The end of the corrugated pipe 1 is fixed to the robot by the cooperation of the base 201 and the fixing block 202.

[0032] It also includes a fixed block 203 and a linkage unit; several fixed blocks 203 are slidably connected on the ring 2; and the linkage unit is connected on the ring 2.

[0033] The linkage unit includes a spring 204 and a linkage block 205; the first ring 2 and the second ring 3 are rotatably connected; two springs 204 are fixedly connected to each second fixed block 203, and the springs 204 are made of alloy material; several linkage blocks 205 are fixedly connected to the first ring 2, and the linkage blocks 205 are in contact with the corresponding second fixed blocks 203; the contact surfaces of the second fixed blocks 203 and the linkage blocks 205 are all set as inclined surfaces. When the second ring 3 is manually rotated, the second ring 3 drives the linkage blocks 205 to perform circular motion, so that the linkage blocks 205 push the second fixed blocks 203 away from the center line of the second ring 3.

[0034] It also includes auxiliary components, including bump 206 and bump 207; bump 206 is welded on ring 2; and bump 207 is welded on ring 3.

[0035] Initially, the corrugated pipe 1, base 201, and fixing block 202 are separated from each other. First, a person stands on the workbench and erects the corrugated pipe 1 vertically. Then, a metal ball connected to a nylon rope is inserted into the inside of the corrugated pipe 1 from top to bottom. The metal ball falls under the influence of gravity, causing the lower end of the nylon rope to move downwards, so that the lower end of the nylon rope passes through the lower end of the inside of the corrugated pipe 1. At this time, the nylon rope passes through the inside of the corrugated pipe 1, and both ends of the nylon rope are located on the outside of the corrugated pipe 1. Then, the person places the corrugated pipe 1 horizontally on the ground, and inserts the cable and air pipe into the corresponding round hole 91, with the ends of the cable and air pipe slightly exceeding the round hole 91. At this time, the cable and air pipe are in close contact with the threading block 4, and the threading block 4 fixes the cable and air pipe through friction. Then, the ring 2 and its components are manually placed on the right side of the bellows 1. The right end of the nylon rope is then fixed to the middle left side of the threading block 4. The left end of the nylon rope is then manually pulled, causing the threading block 4 and its components to move to the left. This moves the threading block 4 and its components to the inside of the bellows 1, and also moves the left end of the cable and air pipe to the inside of the bellows 1. At this point, the balls 5 distributed on the outer surface of the ring 2 are in contact with the inside of the bellows 1. The nylon rope is then pulled further, causing the ring 2 and its components to move to the left inside the bellows 1, and also moving the cable and air pipe to the left inside the bellows 1, until the left side of the ring 2 is flush with the left end of the bellows 1. During this process, the balls 5 roll on the inner wall of the bellows 1. The ball bearing 5 has a smooth surface and a diameter larger than the width of the inner groove of the bellows 1, allowing it to pass smoothly over the groove. The cable and air pipe ends only slightly extend beyond the circular hole 91, preventing sagging and avoiding difficulties in threading caused by the cable and air pipe ends getting stuck in the inner groove of the bellows 1. Then, the base 201 is manually fixed to the robot, and the end of the bellows 1 is placed inside the base 201. The fixing block 202 is then inserted into the outer side of the bellows 1 end and locked to the base 201 with bolts. At this point, the base 201 and the fixing block 202 work together to clamp the ring 2 and its components, along with the bellows 1, completing the end fixing operation. Then, using external straps or limiting rings, the other positions of the corrugated pipe 1 are fixed at intervals to the outside of the robot to complete the cable and air pipe laying operation. During the operation of the robot, the threading block 4 is equivalent to the existing cable divider, which can limit the air pipe of each cable to avoid entanglement. When in use, the cables and air pipes can be quickly passed through the inside of the corrugated pipe 1 by the cooperation of the first ring 2, the second ring 3, the threading block 4 and the ball 5, without the problem of the cable and air pipe ends getting stuck in the groove inside the corrugated pipe 1, which greatly improves the work efficiency and the convenience of manual operation. At the same time, during the operation of the robot, the threading block 4 is equivalent to the existing cable divider, which can limit the air pipe of each cable to avoid entanglement.

[0036] When the base 201 and the fixing block 202 clamp the ring 2 and its parts and the bellows 1, the bellows 1 is only squeezed onto the rolling balls 5, resulting in relatively low stability. Therefore, when the left side of the ring 2 is flush with the left end of the bellows 1, the protrusions 206 and 207 are manually moved. Protrusion 206 drives the ring 2 to rotate, and protrusion 207 drives the ring 3 to rotate, causing the ring 2 and the ring 3 to rotate relative to each other, as shown. At this time, the second circular hole 93 moves closer to the third circular hole 94, and the second ring 3 drives the linkage block 205 to perform a circular motion. The linkage block 205 pushes the second fixed block 203 away from the center of the second ring 3 and stretches the spring 204, so that the second fixed block 203 is inserted into the inner groove of the bellows 1, and the surface of the second fixed block 203 away from the center of the second ring 3 contacts the inner surface of the bellows 1. At this time, the second circular hole 93 is aligned with the third circular hole 94, and then the external... Insert the pin into the second round hole 93 and the third round hole 94 to fix the first ring 2 and the second ring 3 together. Then, manually fix the base 201 onto the robot, place the end of the bellows 1 inside the base 201, and then fasten the first fixing block 202 into the outside of the end of the bellows 1. Lock the first fixing block 202 onto the base 201 with bolts. At this time, the first fixing block 202 presses the bellows 1 against the second fixing block 203, stably clamping the bellows 1. The second fixing block 203 is stuck in the groove inside the bellows 1, which can limit the axial direction of the bellows 1 and further increase the stability. In use, the second fixing block 203 replaces the ball bearing 5 to clamp the bellows 1, avoiding the problem of low stability caused by the bellows 1 being squeezed only on the rolling ball bearing 5. The second fixing block 203 is stuck in the groove inside the bellows 1, which can limit the axial direction of the bellows 1 and further increase the stability.

[0037] Example 2: Based on Example 1, as follows Figure 5 and Figure 6 As shown, it also includes a long rod 208; the long rod 208 is threaded through the middle of the wire-threading block 4; the middle of the long rod 208 is set as a frustum.

[0038] Both ends of the long rod 208 are provided with flanges to prevent the long rod 208 from falling off the wire threading block 4.

[0039] It also includes protective blocks 209; five protective blocks 209 are welded to the end of the long rod 208.

[0040] The edge of the ring 2 is chamfered, making it easier to insert the ring 2 into the inside of the bellows 1.

[0041] The surface of ball 5 is set to be smooth to reduce friction.

[0042] After fixing the corrugated pipe 1 and its parts to the outside of the robot, the operator needs to pull the cable and air pipe in the circular hole 91 a certain distance so that they can connect to the corresponding parts on the robot's movable end. Therefore, the friction between the threading block 4, the cable, and the air pipe should not be set too high. If the friction is too low, during the threading process, the threading block 4 will cause the cable and air pipe to slide relative to each other due to friction, resulting in the cable and air pipe falling off the threading block 4 and thus threading failure. Therefore, a movable long rod 208 is set in the middle of the threading block 4. When the operator places the ring 2 and its parts on the right side of the corrugated pipe 1, the operator fixes the right end of the nylon rope in the circular hole 95 of the long rod 208, and then pulls the long rod 208 to the left through the nylon rope. The long rod 208 drives the threading block 4 and its parts to the left, so that the threading block 4 and its parts move to the left side of the inner side of the corrugated pipe 1. During this process, if Figure 5 As shown, the frustum-shaped portion in the middle of the long rod 208 has a smaller diameter on the left and a larger diameter on the right. This allows the long rod 208 to apply a leftward squeezing force to the threading block 4, causing the threading block 4 to deform adaptively near the circular hole 91 and the narrow groove 92. This compresses the cable and air tube tightly. The greater the tension and resistance, the stronger the deformation of the threading block 4, resulting in a stronger compressive force on the cable and air tube. This effectively prevents the cable and air tube from falling off during the threading process. After threading is completed, the long rod 208 is manually pushed to the right inside the threading block 4, causing the long rod 208 to stop squeezing the threading block 4, thus reducing the squeezing force of the threading block 4 on the cable and air tube. This allows for easy manual operation of the cables and air pipes. During the threading process, the long rod 208 applies pressure to the threading block 4, causing it to deform and compress the cables and air pipes. The greater the tension and resistance during threading, the greater the pressure exerted by the long rod 208 on the threading block 4, and the greater the compressive force of the threading block 4 on the cables and air pipes. This effectively prevents the cables and air pipes from coming loose. When connecting the cables, the operator only needs to push the long rod 208 to the right inside the threading block 4 to reduce the pressure exerted by the threading block 4 on the cables and air pipes, allowing for easy manual operation of the cables and air pipes.

[0043] During the threading process, if the resistance encountered by the ring 2 and its components is too great, the long rod 208 risks detaching from the threading block 4, leading to threading failure. Therefore, a protective block 209 is installed at the right end of the long rod 208. When the ring 2 and its components encounter great resistance during threading, the long rod 208 moves to the left relative to the threading block 4, causing the protective block 209 to move to the left, making it contact the ring 2. Then, the protective block 209 pushes the ring 2 and its components to the left. At this time, the long rod 208 and the threading block 4 no longer move relative to each other, effectively preventing the long rod 208 from falling off. In other words, when the ring 2 and its components encounter great resistance during threading, the protective block 209 can push the ring 2 and its components to the left, preventing the long rod 208 from falling off.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
