Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 6 As shown, this embodiment provides a device for making dumbbell-shaped samples of wires and cables, including a base plate 1. A dividing mechanism is fixedly connected to one side of the top surface of the base plate 1. The dividing mechanism includes a fixed seat 2 fixedly connected to the top surface of the base plate 1. The top surface of the fixed seat 2 is provided with a first groove 3 for placing the cable. Limiting parts are symmetrically provided on both sides of the fixed seat 2. A dividing part is provided above the fixed seat 2. A pushing mechanism is provided on one side of the base plate 1. A cutting mechanism is provided on the side of the fixed seat 2 away from the pushing mechanism.

[0027] The base plate 1 serves as the basic platform. The fixing seat 2 of the segmentation mechanism positions the cable through the first groove 3. The limiting part clamps the cable from both sides, and the segmentation part descends to perform longitudinal cutting. The pushing mechanism pushes the cut cable segment to the cutting mechanism area. The dumbbell-shaped sample is cut by the cutting mechanism. This invention can realize the full automation of the process from cable fixing to sample preparation. It has a compact structure and the modules work together to improve operational efficiency and accuracy.

[0028] The scheme is further optimized. The limiting part includes a first slide groove 4 set on the top of the fixed base 2.

[0029] The two first sliders 6 slide along the first groove 4 to adjust the cable clamping position according to the cable length.

[0030] In a further optimized design, the first driving component includes a first motor fixedly connected to the first cavity 5, and the output shaft of the first motor is fixedly connected to a forward and reverse screw 9, which is threadedly connected to the first slider 6.

[0031] In a further optimized design, the limiting rod 8 is provided with a first through hole 10, the limiting rod 8 is slidably connected in the first through hole 10, the top of the first through hole 10 is provided with a second groove 11, the top surface of the limiting rod 8 is fixedly connected with a first connecting plate 12, the first connecting plate 12 is slidably connected in the second groove 11, a first spring 13 is fixedly connected between the first connecting plate 12 and the second groove 11, and a first electric telescopic rod 14 is fixedly connected in the second groove 11 on the side away from the first spring 13.

[0032] The first motor drives the forward and reverse lead screw 9 to rotate, causing the first slider 6 to move symmetrically within the first slide groove 4, adjusting the spacing of the limit rods 8 to accommodate cables of different lengths. The first spring 13 cooperates with the first electric telescopic rod 14 to achieve both elastic clamping and rigid fixing modes for the limit rods 8. When it is necessary to clamp the cable, the first electric telescopic rod 14 retracts, causing the spring to press against the first connecting plate 12, further causing the limit rods 8 to press against the cable. When it is necessary to release, the first electric telescopic rod 14 extends and presses against the first connecting plate 12, causing the first connecting plate 12 to move towards the side closer to the first spring 13, thereby causing the limit rods 8 to move away from the cable.

[0033] In a further optimized design, the dividing section includes multiple first connecting rods 15 fixed to the top surface of the base plate 1. A second connecting plate 16 is fixed to the top surface of the first connecting rods 15. A second sliding groove 17 is provided on the second connecting plate 16.

The dividing blade 20 is located above the first groove 3. A second driving member is drivenly connected to the second slider 18. The second driving member is fixed to the top surface of the second connecting plate 16.

[0034] In a further optimized design, the second driving component includes a second connecting seat 21 fixedly connected to the second slider 18. The second connecting seat 21 is slidably connected to the top surface of the second connecting plate 16. A second motor 22 is fixedly connected to one side of the second slide groove 17.

A third connecting plate 24 is rotatably connected to the end of the first lead screw 23 away from the second motor 22. The third connecting plate 24 is fixedly connected to the top surface of the second connecting plate 16.

[0035] The second motor 22 drives the first lead screw 23 to rotate, which in turn drives the second slider 18 to move along the second slide groove 17 via the second connecting seat 21, adjusting the horizontal position of the dividing blade 20. The second electric telescopic rod 19 drives the dividing blade 20 to rise and fall vertically, completing the longitudinal cutting of the cable. The lead screw transmission achieves precise positioning of the cutting position (positioning accuracy ±0.05mm), and the electric telescopic rod enables precise control of the cutting depth.

[0036] The scheme is further optimized. The pushing mechanism includes a fourth connecting plate 25 fixedly connected to the base plate 1. A third electric telescopic rod 26 is fixedly connected to one end of the fourth connecting plate 25 near the fixed seat 2.

[0037] The third electric telescopic rod 26 extends, and the push plate 27 pushes the segmented cable section from the fixed base 2 to the gripping area of ​​the robotic arm 29. This achieves automatic transfer of the cable section, reduces manual intervention, and improves process continuity.

[0038] In a further optimized design, a fifth connecting plate 28 is symmetrically fixed to both sides of the base plate 1 near the cutting mechanism. A robotic arm 29 is fixed to the top surface of the fifth connecting plate 28, and a robotic hand 30 is installed at the output end of the robotic arm 29.

[0039] The symmetrically arranged robotic arms 29 perform operations such as grasping cable segments, peeling off shielding layers, and fixing samples to be cut through robotic arms 30.

[0040] The design is further optimized so that the cutting mechanism includes a third connecting seat 31 symmetrically fixed to both sides of the base plate 1. The top surface of the third connecting seat 31 is provided with a third sliding groove 32. A fourth connecting seat 33 is slidably connected to the third sliding groove 32. A cutting blade 34 is slidably connected to the bottom surface of the fourth connecting seat 33. A third driving member is provided on one side of the third sliding groove 32. The third driving member is connected to the fourth connecting seat 33 in a transmission manner.

[0041] In a further optimized design, the third driving component includes a third motor 35 fixedly connected to one side of the third slide groove 32, and the output shaft of the third motor 35 is fixedly connected to a second lead screw 36, which is threadedly connected to the fourth connecting seat 33.

[0042] The third motor 35 drives the second lead screw 36 to rotate, which in turn moves the fourth connecting seat 33 along the third slide groove 32, adjusting the horizontal position of the cutting blade 34; the cutting blade 34 then moves vertically up and down to complete the final cutting of the dumbbell-shaped sample.

[0043] Working principle:

[0044] The cable is placed in the first groove 3 of the fixed base 2. The limiting part drives the first slider 6 to move symmetrically through the forward and reverse screw 9, and the limiting rod 8 elastically clamps the cable. The cutting part adjusts the position of the dividing blade 20 through the screw drive. The first electric telescopic rod 14 drives the dividing blade 20 to descend and complete the longitudinal cutting to form a cable segment of a predetermined length. The push plate 27 of the pushing mechanism pushes the cable segment to the gripping area of ​​the robotic arm 29. The RFID system automatically generates and binds the sample number. The robotic arm 29 grips the cable segment, peels off the outer shielding layer, and fixes both ends of the sample through the cooperation of the two robotic arms 29. The cutting mechanism adjusts the position of the cutting blade 34 through the screw drive to complete the final cutting of the dumbbell-shaped sample. The laser marking head simultaneously etches the QR code information.
