A cable harness reel for robots

Abstract

This utility model relates to the field of cable spool technology, and in particular to a cable spool for robots, comprising a first spool, a second spool, and a wire assembly. A fixed frame is rotatably connected to one side of the first spool. The wire assembly is disposed on one side of the first spool, with one end of the wire assembly near the fixed frame connected to the fixed frame via a mounting bracket. The wire assembly includes a reciprocating screw, a pressing roller, and a wire wheel. Through the design of the reciprocating screw, pressing roller, and wire wheel, and in conjunction with a transmission wheel, transmission rigging, drive wheel, and output motor, when the output motor drives the first spool to rotate, the drive wheel and transmission rigging drive the transmission wheel and reciprocating screw to rotate. Simultaneously, due to the limiting block provided at the bottom of the wire wheel cooperating with the mounting bracket, the reciprocating screw drives the wire wheel to reciprocate, ensuring that the cable reciprocates with the rotation of the first spool, guiding the cable to be evenly wound around the outer cylindrical surface of the spool shaft.

Description

Technical Field

[0001] This utility model relates to the field of cable harness technology, and in particular to a cable harness for use in robots. Background Technology

[0002] A cable reel, also known as a wire winder, cable spool, or cable tray, is a tool used to organize, store, and portable unwind cables (such as power cords, data cables, hoses, etc.). It works by winding cables around a disc-shaped structure, preventing clutter and facilitating use and storage.

[0003] In the use of existing cable reels, cables are usually wound directly onto the reel manually or mechanically. However, most existing cable reels lack automatic cable routing functions, which results in the cables not being evenly and neatly arranged on the reel during the winding process. This leads to random stacking or cross-winding of cables, causing knots and messy tangles during subsequent cable unwinding, thus affecting efficiency.

[0004] Therefore, in order to solve the above-mentioned technical problems, the inventors have proposed a cable harness reel for robots. Utility Model Content

[0005] The purpose of this utility model is achieved through the following method: a cable harness reel for robots, comprising a first reel, a second reel, and a wire assembly. A fixed frame is rotatably connected to one side of the first reel. The second reel is movably disposed on the side of the first reel away from the fixed frame. The shaft of the second reel is disposed in the middle of the shaft of the first reel. A receiving groove matching the shaft of the second reel is provided on the shaft of the first reel near the shaft of the second reel. The wire assembly is disposed on one side of the first reel, and the end of the wire assembly near the fixed frame is connected to the fixed frame via a mounting bracket. The components include a reciprocating lead screw, a pressing roller, and a guide wheel. The reciprocating lead screw is rotatably mounted in the middle of the mounting frame.

[0030] It should be noted that the transmission rigging 13 is a belt structure, but it can also be a chain structure or a synthetic fiber belt structure. No specific limitation is made here. The attached drawings are only for illustration and are not intended to limit the specific type of transmission rigging 13. Those skilled in the art can make reasonable selections according to actual needs, as long as the rigging has sufficient strength and safety factor.

[0031] The specific form of the drive wheel 14 and the transmission wheel 12 is not limited. The attached figure is only an example. The actual design should be adjusted according to the type of transmission rigging 13 and the operating conditions. It is only necessary to meet the requirements of effectively guiding and limiting the rigging and reducing abnormal wear.

[0032] The center point of the mounting frame 5 is aligned with the center point of the side flange of the first reel 1 near the second reel 2. The reciprocating screw 6, the pressing roller 7, and the end of the mounting frame 5 near the second reel 2 all extend toward the second reel 2.

[0033] An adjusting bolt 19 is provided above the adjusting block 10. The screw of the adjusting bolt 19 extends toward the mounting frame 5. The screw of the adjusting bolt 19 passes through the adjusting block 10 and is rotatably connected to the mounting frame 5. The adjusting block 10 and the screw of the adjusting bolt 19 are threaded together. The adjusting block 10 is rotatably connected to one side of the adjusting block 10. A smooth rod position 20 is provided in the middle of the reciprocating bottom rod. A partition block 21 is sleeved on the smooth rod position 20. The partition block 21 is fixedly connected to the mounting frame 5.

[0034] The second reel 2 has a guide protrusion 22 at one end of its shaft core near the first reel 1. The inner wall of the receiving groove 4 has a guide groove 23 that matches the guide protrusion 22 at a position near the guide protrusion 22. The guide groove 23 has a locking groove 24 at one end of its shaft core near the second reel 2. The locking groove 24 extends along the circumferential direction of the inner wall of the shaft core, and the included angle between the starting point and the ending point of the rotating groove is 90°.

[0035] A limiting hole 25 is provided on the top surface of the flange near the end of the first reel 1 near the second reel 2. The limiting hole 25 extends in the direction of the receiving groove 4. A threaded mounting groove 26 is provided at the upper end of the limiting hole 25. A locking pin 27 is installed in the limiting hole 25. The locking pin 27 extends in the direction of the receiving groove 4. A threaded post 28 that mates with the threaded mounting groove 26 is provided near the position of the locking pin 27 near the position of the threaded mounting groove 26. Slots 29 are provided at both ends of the outer cylindrical surface of the shaft core of the second reel 2. The angle between the center lines of the two slots 29 and the cylindrical circumference of the shaft core is 90°. The groove depth of the slot 29 is the same as the groove depth of the threaded mounting groove 26.

[0036] The first reel 1 is provided with a rotating position 30 on the side near the fixed frame 3 and the second reel 2 is provided with a rotating position 30 on the side near the movable frame 15. The fixed frame 3 and the rotating frame are rotatably connected to the rotating position 30. The output motor 11 is fixedly connected to the fixed frame 3 through the connecting plate 31. The drive shaft of the output motor 11 is fixedly connected to the rotating position 30. The drive wheel 14 is fixedly sleeved on the drive shaft of the output motor 11.

[0037] The working process of this utility model is as follows: In use, the distance between the lower pressure roller 7 and the guide wheel 8 is adjusted by rotating the adjusting bolt 19. One end of the cable is passed through the gap between the lower pressure roller 7 and the guide wheel, and one end of the cable is connected to the outer cylindrical surface of the first reel 1 shaft. The output motor 11 is turned on, and the drive shaft of the output motor 11 drives the rotating position 30 to rotate the first reel 1, so that the cable is wound around the outer cylindrical surface of the first reel 1 shaft. The drive shaft of the output motor 11 drives the drive wheel 14 to rotate. The drive wheel 14 drives the transmission wheel 12 and the reciprocating screw 6 to rotate through the transmission rigging 13. When the reciprocating screw 6 rotates, the limit block 9 provided at the bottom of the guide wheel 8 cooperates with the mounting frame 5, so that the reciprocating screw 6 will drive the guide wheel 8 to reciprocate. At the same time, it ensures that the cable can reciprocate with the rotation of the first reel 1, thereby guiding the cable to be evenly wound around the outer cylindrical surface of the reel shaft.

[0038] When the second reel 2 is needed: rotate the locking pin 27 to separate the threaded post 28 on the locking pin 27 from the threaded mounting groove 26. Since the groove depth of the slot 29 is the same as the groove depth of the threaded mounting groove 26, when the threaded post 28 is separated from the threaded mounting groove 26, the locking post of the locking pin 27 is separated from the slot 29 on the shaft of the second reel 2 near the end of the first reel 1.

[0039] After separation, pull the movable frame 15 to drive the shaft of the second reel 2 to extend out of the receiving groove 4. After extending, rotate the second reel 2 to rotate the guide protrusion 22 into the locking groove 24. Since the angle between the starting point and the ending point of the rotating groove is 90° and the angle between the center lines of the two slots 29 and the cylindrical circumference of the shaft is 90°, when the shaft extends and the guide protrusion 22 rotates into the ending point of the locking groove 24, the slot 29 of the shaft near the receiving groove 4 is aligned with the limit.

[0040] After alignment, the threaded post 28 and the threaded mounting groove 26 can be reinstalled, which will drive the locking pin 27 to insert into the slot 29, thereby locking the second reel 2 after it extends.
