DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides three technical solutions, including the following embodiments:

[0034] Example 1

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9, a cable insulation layer detection device, including a detection seat 1, the detection seat 1 reference Fig. 9 The front and rear sides are open-type designs, and a plurality of cable troughs 2 are arranged at intervals inside the detection seat 1. The cable troughs 2 are arranged at equal intervals, and cables 3 are stacked longitudinally inside the cable troughs 2. A batch detection mechanism 4 for batch damage detection of the insulation layer of the cables 3 is arranged inside the detection seat 1;

[0036] The batch detection mechanism 4 includes a vertical plate 41 fixed inside the detection seat 1, and a plurality of Z-shaped grooves 42 are formed on one side of the vertical plate 41. The Z-shaped grooves 42 are symmetrically distributed around the center of the vertical plate 41, and the center is a vertical groove. Figure 4 A driving assembly 43 is provided on the vertical plate 41, and a plurality of flexible piezoresistive sensors 44 are provided on the driving assembly 43. The flexible piezoresistive sensor 44 is a prior art and is a sensor based on the piezoresistive effect. It has flexible characteristics such as bendability and stretchability. The piezoresistive effect refers to the phenomenon that when a material is subjected to an external pressure, its resistivity changes. In the flexible piezoresistive sensor, this piezoresistive material is made into a specific structure, which can convert these mechanical signals into electrical signals when subjected to mechanical stimulation such as pressure and strain, thereby realizing the detection of physical quantities such as pressure and strain. In this embodiment, the thickness of the damaged cable 3 changes, so the pressure value detected by the flexible piezoresistive sensor 44 here will decrease. That is to say, when the pressure value of the flexible piezoresistive sensor 4 decreases during the movement, it means that the insulation layer of the cable here is damaged to varying degrees. The driving assembly 43 drives the flexible piezoresistive sensor 44 to change the horizontal distance and move downward to perform batch detection on the cables 3.

[0037] The driving assembly 43 includes a fixed plate 431 fixed on the top of the vertical plate 41, a cylinder 432 is fixed on one side of the fixed plate 431, the cylinder 432 is controlled by an external switch and is electrically connected to an external power supply, a moving seat 433 is fixed on the output end of the cylinder 432, a T-slot 434 is penetrated through one side of the moving seat 433, a plurality of connecting columns 435 are slidably connected inside the T-slot 434, a round seat 436 is fixed to the top of the plurality of connecting columns 435, and the round seat 436 slides horizontally inside the T-slot 434.

[0038] The bottom ends of the plurality of connecting columns 435 are all fixed with pitch change rods 437, the bottom ends of the plurality of pitch change rods 437 are all slidably connected with vertical rods 438, the top ends of the plurality of vertical rods 438 extend to the inside of the pitch change rod 437, the bottom ends of the plurality of vertical rods 438 are all fixed with flexible piezoresistive sensors 44, the outer surfaces of the plurality of vertical rods 438 are all sleeved with springs 439, the top ends of the springs 439 are fixed to the bottom ends of the pitch change rods 437, the bottom ends of the springs 439 are fixed to the top ends of the flexible piezoresistive sensors 44, and the pitch change rods 437 are all slidably connected with vertical rods 438, the top ends of the vertical rods 438 are all extended to the inside of the pitch change rod 437, the bottom ends of the vertical rods 438 are all fixed with flexible piezoresistive sensors 44, and the pitch change rods 437 are all slidably connected to the bottom ends of the vertical rods 438. A connecting plate 4310 is fixed to one side of the distance rod 437, and a horizontal column 4311 is fixed to one side of the connecting plate 4310. One end of the horizontal column 4311 passes through the Z-shaped groove 42 and extends to the outside of the Z-shaped groove 42. The outer surface of the horizontal column 4311 is slidably connected to the inner surface of the Z-shaped groove 42. A circular plate 4312 is fixed to one end of the horizontal column 4311. When the cylinder 432 is started, the moving seat 433 is driven to move downward, and at the same time, the horizontal column 4311 is driven to move downward in the Z-shaped groove 42 and dispersed equidistantly around.

[0039] By setting up the batch detection mechanism 4, batch damage detection of the cables 3 after production is realized, and the damage of the insulation layer of the cable 3 is accurately detected by the change of the pressure value of the flexible piezoresistive sensor 44 during the detection process, which greatly improves the detection efficiency.

[0040] Example 2

[0041] Based on Example 1, see Figure 1 , Figure 2 , Figure 6 As shown, a clamping assembly 5 for compressing and gathering the longitudinally stacked cables 3 is provided on one side of the circular plate 4312, and the clamping assembly 5 includes a fixed block 51 fixed on one side of the circular plate 4312, a square box 52 is fixed to the bottom of the fixed block 51, a slide plate 53 is slidably connected to the bottom of the square box 52, the top of the slide plate 53 extends to the interior of the square box 52, a spring 2 54 is fixed between the top of the slide plate 53 and the top wall of the square box 52, and a clamping arc block 55 is fixed to the bottom of the slide plate 53. The setting of the spring 2 54 can ensure that the clamping arc block 55 compresses the cable 3, and the spring coefficient of the spring 2 54 is small. As long as the clamping arc block 55 compresses the cable 3 so that no gap is generated between the longitudinally stacked cables 3, it will not affect the belt 66 driving the cable 3 to rotate and change surfaces.

[0042] By using the driving component 43 and the clamping component 5 in coordination, the cables 3 in the detection seat 1 can be stacked layer by layer in the cable trough 2. The driving component 43 synchronously drives the clamping component 5 to move downward, so that the clamping arc block 55 clamps the cables 3 in the cable trough 2, reduces the gaps between the cables 3, keeps the cables 3 horizontal, and effectively prevents the cables 3 from bending. The driving component 43 drives the clamping component 5 to move downward while spreading the clamping component 5 around. When the cables 3 are placed in the detection seat 1, they are irregularly gathered and placed. The clamping component 5 can separate the cables 3 while spreading around, so that the cables 3 fall into the cable trough 2 regularly and are stacked vertically.

[0043] Both sides of the detection seat 1 are provided with a pushing unit 8 for pushing the cable 3 to move horizontally. The pushing unit 8 includes a U-shaped plate 81 fixed to one side of the detection seat 1, and a cylinder 3 82 is fixed to one side of the U-shaped plate 81. The cylinder 3 82 is controlled by an external switch and is electrically connected to an external power supply. A side plate 83 is fixed to the output end of the cylinder 3 82, and a plurality of pushing blocks 84 are fixed to one side of the side plate 83. When the pushing block 84 moves, the corresponding longitudinally stacked cable 3 can be pushed. Figure 1 .

[0044] By arranging the pushing unit 8 at the front and rear of the detection seat 1, the cable 3 is pushed forward and backward, so that during the reciprocating pushing process of the cable 3, the flexible piezoresistive sensor 44 is used to perform damage detection on the surface of the cable 3, thereby greatly improving the detection efficiency.

[0045] Example 3

[0046] Based on Example 2, see Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, a rotating face-changing component 6 for driving the cable 3 to rotate and change faces is provided on the vertical plate 41, and the rotating face-changing component 6 includes an L-shaped seat 61 fixed on both sides of the movable seat 433, and one side of the two L-shaped seats 61 is rotatably connected to a rotating rod 62, and one side of one of the L-shaped seats 61 is fixed with a motor 63, and the motor 63 is a three-phase asynchronous motor, which can be reversed, controlled by an external switch, and electrically connected to an external power supply. The motor 63 drives the rotating rod 62 to rotate, and the output end of the motor 63 is fixed to one end of the rotating rod 62 through a coupling.

[0047] A vertical plate 64 is arranged between the two rotating rods 62. One end of the two rotating rods 62 passes through the vertical plate 64 and extends to the outside of the vertical plate 64. The outer surfaces of the two rotating rods 62 are rotatably connected to the inner surface of the vertical plate 64. A pulley 65 is fixed at one end of the two rotating rods 62. The two pulleys 65 are connected by a belt 66.

[0048] By setting the rotating surface changing component 6, the uppermost cable 3 is driven by the belt 66 to rotate and change its surface, so that the flexible piezoresistive sensor 44 can fully and evenly detect the outer surface of the cable 3, thereby improving the accuracy of the detection.

[0049] The vertical plate 64 is provided with a pressure fitting unit 7 which allows the bottom of the belt 66 to always keep in squeezing contact with the top of the cable 3. The pressure fitting unit 7 includes an L-shaped plate 71 fixed to one side of the vertical plate 64. A cylinder 72 is fixed to the top of the L-shaped plate 71. The cylinder 72 is controlled by an external switch and is electrically connected to an external power supply. A horizontal plate 73 is fixed to the output end of the cylinder 72. A plurality of square plates 74 are fixed to one side of the vertical plate 64. The tops of the plurality of square plates 74 are all slidably connected to vertical pipes 75. The bottom ends of the vertical pipes 75 are A moving rod 76 is slidably connected, the top of which extends to the inside of the vertical tube 75, and a pressure block 77 is fixed to the bottom of the moving rod 76. A spring three 78 is sleeved on the outer surface of the moving rod 76, the top of the spring three 78 is fixed to the bottom end of the vertical tube 75, and the bottom of the spring three 78 is fixed to the top of the pressure block 77. The bottom of the pressure block 77 contacts and squeezes the inner side of the belt 66. Through the arrangement of the spring three 78 and the pressure block 77, the pressure block 77 can always press down the belt 66, so that the belt 66 maintains a certain tension.

[0050] When dust and impurities adhere to the cables 3 so that the uppermost cables 3 are not in the same plane, the pressure fitting unit 7 is provided to enable the belt 66 to deform adaptively, always pressing the uppermost cables 3, allowing the cables 3 to rotate and change plane effectively.

[0051] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0052] During operation, the cable 3 is placed in the detection seat 1, and the cylinder 1 432 is started, so that the cylinder 1 432 drives the moving seat 433 to move downward, and then the moving seat 433 drives the cross column 4311 to slide in the Z-shaped groove 42 and change the pitch, so that the clamping component 5 is dispersed to the surroundings, and the cables 3 in the detection seat 1 are separated by the dispersion of the clamping component 5, so that the cables 3 fall into the cable groove 42 for longitudinal regular stacking, and when the clamping component 5 moves downward, the clamping arc block 55 presses the cable 3, so that the cables 3 are tightly stacked and compressed in the cable groove 42, and at the same time, the pitch-changing rod 437 moves downward and changes the pitch to separate, so that the flexible piezoresistive sensor 44 is pressed on the uppermost cable 3, and the front cylinder 3 82 is started, so that the cylinder 3 82 drives the side plate 83 and the push block 84 to move, and the push block drives the cable 3 to move backward. In the process of the movement of the cable 3, the flexible piezoresistive sensor 44 presses the upper surface of the cable 3 To perform damage detection, start the rear cylinder three 82, push the cable 3 back to its original position, start the motor 63, so that the motor 63 drives the rotating rod 62 to rotate, and then drives the pulley 65 to rotate. The two pulleys 65 drive the belt 66 to transmit, and the belt 66 and the cable 3 are pressed tightly. During transmission, the belt 66 drives the uppermost cable 3 to rotate and change surfaces, and then pushes the cable 3 to move, and repeatedly performs damage detection, starts the cylinder two 72, and the cylinder two 72 drives the cross plate 73 to move downward, and the cross plate 73 drives the vertical pipe 75 to slide downward, and then drives the pressing block 77 to press the belt 66 downward. At the same time, the spring three 78 is compressed, and the moving rod 76 slides into the inside of the vertical pipe 75. When dust and impurities are stuck to the cable 3 so that the upper layer of the cable 3 is not in the same plane, the belt 66 can also be adaptively deformed to always press the uppermost cable 3. After the uppermost cable 3 is detected, the cable 3 is removed and tested layer by layer.
