[0002] During robot installation, cables and air pipes need to be laid outside the robot. To prevent interference between the cables and air pipes during robot operation, existing technologies involve inserting the cables and air pipes into a corrugated tube, which is then fixed to the outside of the robot to protect them. Because the corrugated tube is relatively long and its inner side is uneven, when manually controlling the cables and air tubes to pass through the inner side of the corrugated tube, the heads of the cables and air tubes will droop and contact the grooves on the inner side of the corrugated tube, causing them to get stuck. At this time, manual adjustment of the positions of the cables and air tubes is required frequently to smoothly pass them through, making the operation cumbersome and inefficient.

[0003] In summary, this application proposes an automated robot harness fixing device to improve the above-mentioned technical problems. Summary of the Invention

[0008] Further explanation: in the above-mentioned automated robot harness fixing device, the linkage unit includes a spring and a linkage block; circular ring 1 is rotatably connected to circular ring 2; a number of springs are fixed to each fixed block 2, and the spring is fixed to circular ring 1; a number of linkage blocks are fixed to circular ring 1, and the linkage blocks are in contact with the corresponding fixed block 2; the contact surfaces of fixed block 2 and the linkage blocks are both set as inclined surfaces.

[0009] Further explanation: the above-mentioned automated robot harness fixing device also includes an auxiliary component, which includes bump one and bump two; bump one is fixedly connected to circular ring one; and bump two is fixedly connected to circular ring two.

[0010] Further explanation: the above-mentioned automated robot harness fixing device also includes a long rod; the long rod is passed through the middle of the threading block; and the middle of the long rod is set as a frustum.

[0015] The beneficial effects of the present invention are: 1. Through the cooperation of the first and second rings, the threading block and the ball bearing, the cables and air tubes can be quickly passed through the inner side of the corrugated tube without the problem of the ends of the cables and air tubes being stuck in the grooves inside the corrugated tube, which greatly improves the work efficiency and convenience of manual operation. At the same time, during the operation of the robot, the threading block can be equivalent to the wire splitter in the prior art, which can limit the air tube of each cable to avoid entanglement. Second, the bellows is clamped by the second fixing block instead of the ball, which avoids the problem of low stability caused by the bellows being squeezed only on the rolling ball. In addition, the second fixing block is stuck in the groove inside the bellows, which can limit the axial direction of the bellows and further increase stability. 3. During the threading process, the long rod applies squeezing force 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 squeezing force of the long rod on the threading block, and the greater the pressing force of the threading block on the cable and air tube, effectively avoiding the problem of the cable and air tube falling off. When wiring, the operator only needs to push the long rod to the right inside the threading block to reduce the squeezing force of the threading block on the cable and air tube, so that the operator can easily pull the cable and air tube to perform the wiring operation; 4. When the ring 1 and the parts on it encounter great resistance during the threading process, the protective block can be used to push the ring 1 and the parts on it to move 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example 1: An automated robot harness fixing device, such as Figures 1-4As shown, it includes a bellows 1 and a circular ring 2; a circular ring 2 is provided on the side of the bellows 1, and the circular ring 2 is made of plastic; it also includes a circular ring 3, a threading block 4, a ball 5 and a fixing component; the inner side of the circular ring 2 is connected to the circular ring 3; the inner side of the circular ring 2 is fixedly connected to the threading block 4; five circular holes 91 are provided on the threading block 4; five narrow grooves 92 are provided on the threading block 4, and the narrow grooves 92 are connected to the corresponding circular holes 91, and all the narrow grooves 92 are connected to each other; the threading block 4 is elastic; a number of balls 5 are rotatably connected to the outer ring surface of the circular ring 2; a fixing component is connected to the bellows 1.

[0020] The fixing assembly includes a base 201 and a fixing block 202; the base 201 is provided at the end of the bellows 1, and the base 201 is set to a plastic material; the base 201 is bolted to a fixing block 202, and the fixing block 202 is in contact with the bellows 1. The end of the bellows 1 is fixed to the robot through the cooperation between the base 201 and the fixing block 202.

[0021] It also includes a fixed block 203 and a linkage unit; a plurality of fixed blocks 203 are slidably connected to the ring 1 2; and the ring 1 2 is connected to the linkage unit.

[0022] The linkage unit includes a spring 204 and a linkage block 205; the circular ring 1 2 is rotatably connected to the circular ring 2 3; each fixed block 203 is fixed with two springs 204, the springs 204 are fixed to the circular ring 1 2, and the springs 204 are set to an alloy material; a number of linkage blocks 205 are fixed to the circular ring 1 2, and the linkage blocks 205 are in contact with the corresponding fixed blocks 2 203; the contact surfaces of the fixed blocks 203 and the linkage blocks 205 are both set to inclined surfaces, and the circular ring 2 3 is manually driven to rotate, and the circular ring 2 3 drives the linkage block 205 to perform a circular motion, so that the linkage block 205 pushes the fixed block 2 203 away from the center line of the circular ring 2 3.

[0023] It also includes an auxiliary component, which includes a first bump 206 and a second bump 207; the first bump 206 is welded on the first ring 2; and the second bump 207 is welded on the second ring 3.

[0024] In the initial state, the bellows 1, the base 201 and the fixing block 202 are separated from each other; first, a person stands on the workbench to stand the bellows 1 upright, and then inserts the metal ball connected with the nylon rope into the inner side of the bellows 1 from top to bottom. The metal ball falls under the action of gravity and drives the lower end of the nylon rope to move downward, so that the lower end of the nylon rope passes through the lower end of the inner side of the bellows 1. At this time, the nylon rope passes through the inner side of the bellows 1, and both ends of the nylon rope are located outside the bellows 1. Then, the person manually places the bellows 1 horizontally on the ground, and then inserts the cable and the air pipe into the corresponding circular hole 91, and makes the ends of the cable and the air pipe slightly protrude from the circular hole 91. At this time, the cable and the air pipe are in close contact with the threading block 4, and the threading block 4 fixes the cable and the air pipe through friction. Then manually place the ring 2 and the parts on it on the right side of the corrugated tube 1, and then fix the right end of the nylon rope to the middle of the left side of the threading block 4. Then, manually pull the left end of the nylon rope to move, so that the nylon rope drives the threading block 4 and the parts on it to move to the left, so that the threading block 4 and the parts on it move to the inside of the corrugated tube 1, and drive the cable and the left end of the air pipe to move to the inside of the corrugated tube 1. At this time, the balls 5 distributed on the outer surface of the ring 2 are in contact with the inside of the corrugated tube 1. Continue to pull the nylon rope to make the ring 2 and the parts on it move to the left inside the corrugated tube 1, and drive the cable and the air pipe to move to the left inside the corrugated tube 1 until the left side of the ring 2 is flush with the left end of the corrugated tube 1. During this process, the balls 5 roll on the inner wall of the corrugated tube 1. Because the surface of the ball 5 is smooth and the diameter of the ball 5 is larger than the width of the inner groove of the bellows 1, the ball 5 can smoothly pass through the inner groove of the bellows 1, and the ends of the cable and the air pipe only slightly exceed the circular hole 91, and will not sag, thereby avoiding the problem of difficult threading operation caused by the ends of the cable and the air pipe being 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 on the inside of the base 201, and then the fixing block 202 is buckled into the outside of the end of the bellows 1, and the fixing block 202 is locked to the base 201 by bolts. At this time, the base 201 and the fixing block 202 are matched to clamp the ring 2 and the parts on it and the bellows 1 to complete the end fixing operation. Operation, and then use external straps or limit rings to fix the other positions of the corrugated tube 1 at intervals on 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 wire splitter in the prior art, which can limit the air pipe of each cable to avoid entanglement. When in use, the ring 1 2, the ring 2 3, the threading block 4 and the ball 5 are matched to make the cable and air pipe quickly pass through the inside of the corrugated tube 1, and there will be no problem of the cable and air pipe ends being stuck in the groove inside the corrugated tube 1, which greatly improves the work efficiency and convenience of manual operation. At the same time, during the operation of the robot, the threading block 4 can be equivalent to the wire splitter in the prior art, which can limit the air pipe of each cable to avoid entanglement.

[0025] When the base 201 and the fixing block 1 202 clamp the ring 1 2 and the parts thereon and the bellows 1, the bellows 1 is only squeezed on the rolling ball 5, and the stability is relatively low. Therefore, when the left side of the ring 1 2 is flush with the left end of the bellows 1, the protrusion 1 206 and the protrusion 2 207 are manually moved, and the protrusion 1 206 drives the ring 1 2 to rotate, and the protrusion 2 207 drives the ring 2 3 to rotate, so that the rings 1 2 and the rings 2 3 rotate relative to each other, as shown At this time, the circular hole 2 93 moves close to the circular hole 3 94, and the circular ring 2 3 drives the linkage block 205 to perform a circular motion. The linkage block 205 pushes the fixed block 203 to move away from the center of the circular ring 2 3 and stretches the spring 204, so that the fixed block 203 is inserted into the inner groove of the bellows 1, and the surface of the fixed block 203 away from the center of the circular ring 2 3 contacts the inner side of the bellows 1. At this time, the circular hole 2 93 is aligned with the circular hole 3 94, and then the external The pin is inserted into the second circular hole 93 and the third circular hole 94 to fix the circular ring 1 2 and the circular ring 2 3 together. Then, the base 201 is manually fixed to the robot, and the end of the bellows 1 is placed on the inner side of the base 201. Then the fixing block 1 202 is buckled into the outer side of the end of the bellows 1 and the fixing block 1 202 is locked on the base 201 by the bolt. At this time, the fixing block 1 202 presses the bellows 1 on the fixing block 203, clamping the bellows 1 stably, and the 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. When in use, the bellows 1 is clamped by the fixing block 203 instead of the ball 5, avoiding the problem of low stability caused by the bellows 1 being squeezed only on the rolling ball 5, and the 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.

[0026] Example 2: Based on Example 1, Figure 5 and Figure 6 As shown, a long rod 208 is also included; the long rod 208 is passed through the middle of the threading block 4; the middle of the long rod 208 is set as a frustum.

[0027] Both ends of the long rod 208 are provided with flanges to prevent the long rod 208 from falling off from the threading block 4.

[0028] It also includes a protection block 209; five protection blocks 209 are welded to the end of the long rod 208.

[0029] The edge of the ring 1 2 is chamfered to make it easier for the ring 1 2 to be inserted into the inner side of the bellows 1 .

[0030] The surface of the ball 5 is set to be smooth to reduce friction.

[0031] After the bellows 1 and the parts on it are fixed to the outside of the robot, it is necessary to manually pull the cable and air pipe in the circular hole 91 out a certain distance so that they can be docked on the corresponding parts at the movable end of the robot. Therefore, the friction between the threading block 4, the cable and the air pipe is not set too large. If the friction is too small, during the threading process, the threading block 4 will cause the cable and air pipe to slide relative to each other through the friction, causing the cable and air pipe to fall off the threading block 4, thereby causing threading failure. Therefore, a movable long rod 208 is set in the middle of the threading block 4. When the circular ring 2 and the parts on it are manually placed on the right side of the bellows 1, the right end of the nylon rope is manually fixed in the circular hole 95 of the long rod 208, and then the long rod 208 is pulled to the left by the nylon rope, and the threading block 4 and the parts on it are driven to move to the left by the long rod 208, so that the threading block 4 and the parts on it move to the left inside the bellows 1. In this process, Figure 5 As shown, the diameter of the cone portion in the middle of the long rod 208 is small on the left and large on the right, so that the long rod 208 can exert a leftward squeezing force on the threading block 4, so that the threading block 4 near the circular hole 91 and the narrow groove 92 undergoes adaptive deformation, pressing the cable and the trachea tightly. The greater the tension and resistance, the stronger the deformation of the threading block 4, and thus the stronger the pressing force on the cable and the trachea, which can effectively prevent the cable and the trachea from falling off during the threading process. After the threading is completed, the long rod 208 is manually pushed to the right inside the threading block 4 to stop squeezing the threading block 4, thereby reducing the squeezing force of the threading block 4 on the cable and the trachea. This makes it possible for workers to easily pull the cables and air pipes to perform wiring operations. That is, during the threading process, the long rod 208 applies an extrusion pressure to the threading block 4, causing the threading block 4 to deform and compress the cables and air pipes. The greater the tension and resistance during threading, the greater the degree of extrusion of the threading block 4 by the long rod 208, and the greater the pressing force of the threading block 4 on the cables and air pipes, effectively avoiding the problem of cables and air pipes falling off. When wiring, workers only need to push the long rod 208 to the right inside the threading block 4 to reduce the extrusion pressure of the threading block 4 on the cables and air pipes, so that workers can easily pull the cables and air pipes to perform wiring operations.

[0032] During the threading process, if the ring 2 and the parts on it are subjected to too much resistance, the long rod 208 is at risk of falling off the threading block 4, which in turn causes the threading to fail. Therefore, a protective block 209 is set at the right end of the long rod 208. When the ring 2 and the parts on it are subjected to large resistance during the threading process, the long rod 208 moves to the left relative to the threading block 4, and drives the protective block 209 to move to the left, so that the protective block 209 contacts the ring 2, and then pushes the ring 2 and the parts on it to move to the left through the protective block 209. At this time, the long rod 208 and the threading block 4 no longer move relative to each other, effectively avoiding the problem of the long rod 208 falling off. That is, when the ring 2 and the parts on it are subjected to large resistance during the threading process, the protective block 209 can push the ring 2 and the parts on it to move to the left. At this time, the long rod 208 and the threading block 4 no longer move relative to each other, effectively avoiding the problem of the long rod 208 falling off.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
