Description

An automated wire transfer robot for conductor resistance detection Technical Field

[0001] This utility model relates to the technical field of conductor resistance testing equipment, specifically to an automated wire transfer robot for conductor resistance testing. Background Technology

[0002] With continuous social progress and development, and the ongoing advancement of insulation and cabling in urban power grids, the number of overhead insulated cables and power cables is rapidly increasing. Whether for daily life or industrial production, the vital role of wires and cables is indispensable. Therefore, the performance of wires and cables directly affects the user's final electricity consumption and production efficiency, making the accurate testing of the DC resistance of wire and cable conductors paramount. The DC resistance of wire and cable conductors is one of the important indicators characterizing the electrical performance of cables, and the DC resistance test is the primary means of assessing the conductivity of conductors. Accurate measurement of the DC resistance of wire and cable conductors plays a crucial role in the safe use of wires and cables.

[0003] Currently, when testing the conductor resistance of wires, it is necessary to manually lift the wire to be tested onto the clamp, then test the wire with a testing instrument, and finally remove the wire manually after the test is completed.

[0004] Regarding the aforementioned technologies, manually loading and unloading wires is inconvenient and has low testing efficiency. Summary of the Invention

The drive cylinder 23 is fixedly mounted on the base 1 and located on the side of the movable clamp 22 away from the fixed clamp 21. The piston rod of the drive cylinder 23 is fixedly connected to the movable clamp 22. The gaps between the fixed clamp 21 and the movable clamp 22 of each clamp assembly 2 are on the same straight line. A storage box 3 for placing wires is provided on one side of the base 1 in the Y-axis direction, and the storage box 3 has an opening at the top.

[0030] This application discloses an automated wire transfer robot for conductor resistance detection. Referring to Figures 1 and 2, the automated wire transfer robot includes a pair of side frames 4, a pair of horizontal frames 5, a pair of vertical frames 6, a first drive mechanism 7, a first drive assembly 8, and a second drive assembly 9. The two side frames 4 are both vertically arranged, parallel to each other, and horizontally spaced apart. The horizontal frames 5 are horizontally columnar, both horizontally arranged, parallel to each other, and mounted on the two side frames 4. Both ends of each horizontal frame 5 slide towards the top of the two side frames 4 in the X-axis direction. The first drive mechanism 7 is used to drive the horizontal frames. 5. Sliding: The two horizontal frames 5 are slidably mounted on the side of each other in the Y-axis direction with mounting bases 52. The first drive assembly 8 is used to drive the mounting bases 52 to slide. The vertical frame 6 is in the shape of a vertical rod. The two vertical frames 6 are slidably mounted on the side of each of the two mounting bases 52 in the Z-axis direction with the mounting bases 52. The second drive assembly 9 is used to drive the vertical frame 6 to slide. The bottom of each of the two vertical frames 6 is fixedly mounted with a mechanical automatic gripper 10. The mechanical automatic gripper 10 is an electric manipulator, which is the prior art and will not be described in detail here.

[0031] During testing, the base 1 and storage box 3 are placed directly below the two side frames 4. Then, through the cooperation of the first drive mechanism 7, the first drive component 8 and the second drive component 9, the mechanical automatic gripper 10 is moved into the storage box 3 to clamp the wire. Then, through the cooperation of the first drive mechanism 7, the first drive component 8 and the second drive component 9, the mechanical automatic gripper 10 is moved until the wire is inserted between the fixed clamp 21 and the moving clamp 22 of each clamp component 2. The drive cylinder 23 is activated to drive the moving clamp 22 to move towards the fixed clamp 21, thus completing the clamping of the wire. The wire is then tested by a testing instrument.

[0032] Referring to Figure 2, the side frame 4 includes a crossbeam 41 and several columns 42. The crossbeam 41 extends horizontally, and the columns 42 are spaced apart along the length of the crossbeam 41. The top of the columns 42 is fixedly connected to the crossbeam 41. Reinforcing ribs 43 are connected between the columns 42 and the crossbeam 41, so that the entire side frame 4 can be more stable. A pair of reinforcing rods 44 are provided between the two side frames 4. The two reinforcing rods 44 are located at both ends of the side frame 4, and the two ends of the reinforcing rods 44 are fixedly installed on the two side frames 4, thereby further improving the overall stability.

[0033] Referring to Figures 2 and 3, slide rails 45 are fixedly installed on the top of both side frames 4, and sliding seats 51 are fixedly installed at both ends of the cross frame 5. Both sliding seats 51 extend in the sliding direction of the cross frame 5 and are respectively slidably installed on the two slide rails 45. The cross frame 5 and the vertical frame 6 are both equipped with the same type of slide rails 45 for the mounting base 52 and the vertical frame 6 to slide stably. This will not be described in detail here.

[0034] The first drive mechanism 7 includes a pair of mounting plates 71, a pair of first gears 72, a pair of first racks 73, and a third drive assembly. The two mounting plates 71 are fixedly mounted at both ends of the cross frame 5, and the mounting plates 71 are mounted on the side of the cross frame 5 away from the vertical frame 6. The two first gears 72 are rotatably mounted on the two mounting plates 71, and the two first racks 73 are fixedly mounted on the two side frames 4. The first racks 73 extend in the sliding direction of the cross frame 5, and the two first gears 72 mesh with the two first racks 73 respectively. The third drive assembly is used to synchronously drive the two first gears 72 to rotate.

[0035] The third drive assembly includes a connecting rod 74, a pair of couplings 75, and a first drive member. The connecting rod 74 extends in the direction of extension of the crossbeam 5 and is located between the two first gears 72. The two couplings 75 are respectively connected to the two ends of the connecting rod 74, and the ends of the two couplings 75 away from the connecting rod 74 are respectively connected to the shafts of the two first gears 72. The first drive member includes a driving pulley 76, a driven pulley 77, a belt 78, and a servo motor 79. The servo motor 79 is fixedly mounted on the mounting plate 71. The driving pulley 76 is sleeved on the output shaft of the servo motor 79, the driven pulley 77 is sleeved on the shaft of the first gear 72, and the belt 78 is synchronously wound around the driving pulley 76 and the driven pulley 77. Thus, the first gears 72 at both ends of the same crossbeam 5 can be synchronously driven, thereby driving the crossbeam 5 to slide in the X-axis direction.

[0036] Referring to Figures 2 and 4, the first drive assembly 8 includes a second gear 81, a second rack 82, and a second drive member 83. The second gear 81 is rotatably mounted on the mounting base 52, and the second rack 82 extends in the sliding direction of the mounting base 52. The second rack 82 is fixedly mounted on the crossbeam 5, and the second gear 81 meshes with the second rack 82. The second drive member 83 is a motor, and the second drive member 83 is fixedly mounted on the mounting base 52. The output shaft of the second drive member 83 is fixedly connected to the rotating shaft of the second gear 81. Thus, the mounting base 52 can be driven to slide in the Y-axis direction.

[0037] Referring to Figures 2 and 5, the second drive assembly 9 includes a third gear 91, a third rack 92, and a third drive member 93. The third gear 91 is rotatably mounted on the mounting base 52, and the third rack 92 extends in the sliding direction of the vertical frame 6 and is fixedly mounted on the vertical frame 6. The third gear 91 meshes with the third rack 92. The third drive member 93 is a motor and is fixedly mounted on the mounting base 52. The output shaft of the third drive member 93 is fixedly connected to the rotating shaft of the third gear 91. Thus, the vertical frame 6 can be driven to slide in the Z-axis direction.

[0038] Referring to Figures 2 and 3, a pair of buffer blocks 46 are provided on the top of one of the side frames 4 and corresponding to each cross frame 5. The two buffer blocks 46 of the same pair are located on both sides of the sliding direction of the cross frame 5, and the two buffer blocks 46 of the same pair are located at the sliding limit position of the cross frame 5. That is, one of the buffer blocks 46 of the same pair is located at the end position of the corresponding first rack 73, and the other is located at the middle position of the corresponding first rack 73. This is used to prevent the cross frame 5 from derailing or the two mechanical automatic grippers 10 from colliding. Buffer blocks 46 are fixedly installed at both ends of each cross frame 5 and both ends of the vertical frame 6. Their function is the same as that of the buffer blocks 46 provided on the side frame 4, and will not be described again here.

[0039] The implementation principle of a robotic arm for conductor resistance testing according to an embodiment of this application is as follows: First, the base 1 and the storage box 3 are placed directly below the two side frames 4. Then, the servo motor 79, the second drive unit 83, and the third drive unit 93 are started, respectively driving the horizontal frame 5 to slide in the X-axis direction, the mounting base 52 to slide in the Y-axis direction, and the vertical frame 6 to slide in the Z-axis direction, thereby driving the two mechanical automatic grippers 10 to move to the two ends of the wire to be tested in the storage box 3. Then, the two ends of the wire to be tested are clamped by the mechanical automatic grippers 10. Next, the servo motor 79, the second drive unit 83, and the third drive unit 93 are started again, and the mechanical automatic grippers 10 are used to pick up the wire to be tested and transport it to the fixture. After being clamped by the fixture, it can be tested by the testing instrument.
