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.

[0028] See also Figure 1-8The present invention provides a technical solution: a double-layer structure low-voltage integrated distribution box detection device, comprising a first ground rail assembly 1 and a distribution box frame 2 arranged on one side of the first ground rail assembly 1, specifically, a mechanical arm 3 is slidably arranged on the first ground rail assembly 1, a second driving mechanism 7 connected to the mechanical arm 3 is arranged on the base of the mechanical arm 3, the mechanical arm 3 is driven to move along the first ground rail assembly 1 by the second driving mechanism 7, a strong magnetic component 4 is arranged at the arm-hand moving end of the mechanical arm 3, the specific component structure of the strong magnetic component 4 is a strong electromagnet 5, which is a prior art structure, the strong electromagnet 5 is connected to a first driving mechanism 6 arranged on the base of the mechanical arm 3, the strong electromagnet 5 is driven to fail or operate by the first driving mechanism 6, and the specific operation process of the strong electromagnet 5 is to drive the mechanical arm 3 to move to the front of the target distribution box on the first ground rail assembly 1, and then drive the mechanical arm 3 to operate to move the strong electromagnet 5 to fit the wall of the distribution box, adsorb and fix the distribution box, and then transfer the distribution box;

[0029] Among them, the strong electromagnet 5 is attached to the wall of the distribution box so that the flat surface of the strong electromagnet 5 is completely attached to the wall of the distribution box, so as to improve the adsorption and fixing performance of the strong electromagnet 5 on the distribution box, so that the distribution box is transferred from the outside of the first ground rail assembly 1 to the distribution box frame 2 on the inside of the first ground rail assembly 1, and the distribution box can also be transferred from the distribution box frame 2 to the outside of the first ground rail assembly 1;

[0030] The operation process of the above-mentioned robot arm 3 is controlled by the PLC program.

[0031] In this example, the distribution box is divided into two areas, upper and lower, by a layered plate;

[0032] Specifically, a support plate 8 for carrying the distribution box is arranged on the top of the distribution box frame 2, and positioning components 9 are symmetrically arranged on both sides of the support plate 8, and the position of the distribution box transferred to the support plate 8 is adjusted and the distribution box is positioned and fixed by the positioning components 9;

[0033] Among them, two support plates 8 are arranged on the top of each distribution box frame 2, and the bottom of the support plate 8 is supported by a support frame 10;

[0034] The positioning assembly 9 includes a support block 11 fixedly mounted on the side wall of the support frame 10, a first motor 12 is fixedly mounted in the middle area of ​​the support block 11, the output end of the first motor 12 faces upward and a bearing rod 13 is fixedly mounted, a telescopic rod 14 is fixedly mounted on the side wall of the bearing rod 13, the telescopic rod 14 is a hollow structure, and its end penetrates so that the external environment is connected to the internal hollow structure, and three short sliding rails 15 are fixedly mounted on the internal side wall thereof, and the three short sliding rails 15 are slidably connected to the support rod 16 together, and the end of the support rod 16 is a flat surface, and a plurality of first micro pressure sensors 19 are evenly and densely arranged at the end of the support rod 16, and the function of the first micro pressure sensor 19 is to generate data under pressure and transmit the data to the PLC system;

[0035] Among them, after the distribution box is transferred to the top surface of the support plate 8, the first motor 12 is controlled by the PLC program to run, drive the bearing rod 13 to rotate, and then drive the telescopic rod 14 to rotate to a position vertically facing the support plate 8, and then drive the telescopic rod 14 to extend so that the end surface of the telescopic rod 14 is close to the outer wall surface of the distribution box. The four telescopic rods 14 around the distribution box are operated at the same time, and then the position of the distribution box is corrected, so that the distribution box is in a preset positive position, so as to avoid the inclined distribution box causing the distribution box to have an incorrect detection result;

[0036] Among them, after the operation of the four telescopic rods 14 is completed, the support rod 16 is controlled by the PLC program to move outward along the sliding short track 15, and then drives the first micro pressure sensor 19 to be close to the outer wall of the distribution box. If all the first micro pressure sensors 19 can generate data, it means that the connection position of the telescopic rod 14 and the distribution box is correct, and the distribution box can be accurately restricted and fixed. If one or more of the first micro pressure sensors 19 do not generate data, it means that the connection between the telescopic rod 14 and the distribution box is not vertically fitted. If the distribution box is continuously restricted and fixed in this state, the surface of the distribution box will be worn. After detecting whether the distribution box is corrected, the support rod 16 continues to maintain the state of applying pressure to the distribution box, which further restricts and fixes the distribution box.

[0037] In the process of the four telescopic rods 14 correcting the position of a distribution box, the telescopic rods 14 will rotate to match the position movement of the distribution box, and the rotation process is carried out by the bearing rod 13 with the output end of the first motor 12 as the rotating rod. At this time, the first motor 12 is in a passive operation state. If the bearing rod 13 is set as a fixed structure, the distribution box will be damaged in the process of the four telescopic rods 14 correcting the distribution box.

[0038] Among them, a rubber layer is provided on the end wall surface of the telescopic rod 14, which plays a buffering role in the process of restricting and fixing the distribution box;

[0039] Among them, a side plate 17 welded to the support frame 10 is provided below the support block 11, and the side plate 17 is fixedly connected to the first motor 12 through a connecting rod 18, the purpose of which is to improve the stability of the first motor 12 during operation, thereby improving the accuracy of the telescopic rod 14 restricting the distribution box, and also improving the detection accuracy of the support rod 16;

[0040] The telescopic rod 14 is a prior art structure, and a power source is disposed inside the telescopic rod 14.

[0041] Specifically, a second ground rail assembly 20 is arranged between the first ground rail assembly 1 and the distribution box frame 2, the second ground rail assembly 20 is slidably connected to a base 21, a top rail 22 is fixedly installed on the top of the base 21, three metal plates 23 are slidably connected to the top rail 22, a vertical rail 24 is fixedly installed on the side wall of the metal plate 23 facing the distribution box frame 2, a slider 25 is slidably connected to the vertical rail 24, a second motor 26 is fixedly installed on the side wall of the slider 25, a disc 27 is fixedly installed on the output end of the second motor 26, a side rail 33 is fixedly installed on the side wall of the disc 27, two detection plates 28 are slidably installed on the side rail 33, a plurality of spring rods 29 are evenly arranged on the facing surfaces of the two detection plates 28, a clamping plate 30 is fixedly installed on the end of the spring rod 29, and the spring rod 29 has a certain buffering function to provide certain protection for the layered plate;

[0042] The detection plate 28 has a telescopic function, and a plurality of second micro pressure sensors 32 are evenly arranged on the side walls on both sides thereof. The function of the second micro pressure sensors 32 is to generate data under pressure and transmit the data to the PLC system;

[0043] Among them, after confirming that the position of the distribution box has been corrected, the third driving member 31 connected to the base 21 is driven to drive the base 21 to move along the second ground rail assembly 20, driving the three metal plates 23 to move in front of the distribution box in turn for inspection. After the inspection is completed, it moves to the next distribution box for inspection. During this period, the robot arm 3 transfers the distribution box that has been inspected and replaces the next distribution box. The robot arm 3 and the inspection board 28 process the distribution box alternately at the same time, thereby improving the inspection speed of the distribution box. Compared with the previous sampling inspection, this assembly line inspection can realize one-by-one inspection, so that the inspection accuracy of the distribution box is significantly improved;

[0044] Among them, the distribution box is subjected to three tests: internal edge gap test, layered board firmness test, and layered board strength test;

[0045] Internal edge gap detection: Confirm that the position of the distribution box is accurate, drive the metal plates 23 on both sides to move toward the middle metal plate 23, so that the metal plates 23 on both sides move to the inner warehouse area of ​​the distribution box, then drive the matching sliders 25 on the metal plates 23 on both sides to move to the upper warehouse area of ​​the distribution box, and then drive the matching second motors 26 on the metal plates 23 on both sides to drive the disc 27 to rotate, and finally drive the two detection plates 28 of the frame to be aligned up and down. In this embodiment, the two detection plates 28 are vertically distributed up and down in an aligned state. After confirming that the two detection plates 28 are aligned up and down, drive the detection plates 28 to extend until the ends of the detection plates 28 are close to the inner wall of the distribution box, and then The metal plates 23 on both sides are driven to move toward both sides along the top track 22 until the detection plate 28 extending into the upper storage area of ​​the distribution box moves close to the side wall of the upper storage area of ​​the distribution box, and then the slider 25 is driven to move up and down along the vertical track 24, so as to drive the detection plate 28 in contact with the side wall of the upper storage area of ​​the distribution box to move up and down. If the second micro pressure sensor 32 continuously generates data during the up and down movement, it indicates that there is no bending of the side wall of the upper storage area of ​​the distribution box. If the second micro pressure sensor 32 generates data intermittently during the up and down movement, it indicates that there is bending of the side wall of the upper storage area of ​​the distribution box. The cause of the problem of this distribution box is marked in the PLC system for subsequent processing;

[0046] After the detection of the upper storage area of ​​the distribution box is completed, repeat the above operation to detect the lower storage area of ​​the distribution box.

[0047] Layered board firmness test: confirm that the distribution box is in the correct position, drive the middle metal plate 23 to move to the middle position of the support plate 8, and then drive the slider 25 to move along the vertical track 24 to the front area of ​​the layered board. At this time, drive the two detection plates 28 to move outward along the side track 33 to maximize the distance between the two detection plates 28, and then drive the two detection plates 28 to extend until the two detection plates 28 are respectively on the upper and lower sides of the layered board, and then drive the two detection plates 28 to move toward each other along the side track 33 until the clamping plate 30 is close to the layered board. At this point, the two detection plates 28 clamp and fix the layered board in a straight line. Finally, drive the slider 25 to move up and down along the vertical track 24 to perform the first firmness test on the layered board. After the first firmness test is completed, drive the two detection plates 28 that clamp and fix the layered board to retract and then pull the layered board to perform the second firmness test on the layered board;

[0048] The first firmness test is to test whether the layered board is shaken after being installed in the distribution box. If the layered board is broken or shakes in a large range, the resistance to the up and down movement of the detection board 28 will change, which will be marked in the PLC system. The second firmness test is to test whether the layered board is easy to fall off after being installed in the distribution box. If the layered board is separated from the distribution box, the resistance to the inward retraction of the detection board 28 will change, which will be marked in the PLC system.

[0049] The up and down moving distances of the detection plate 28 are all preset values ​​in the PLC system, and the inward retraction distances of the detection plate 28 are all preset values ​​in the PLC system.

[0050] Strength test of the layered plate: the three metal plates 23 move at the same time and are in the position of three equal parts to clamp and fix the layered plate. The detection plates 28 of the three metal plates 23 all clamp and fix the layered plate, and drive the three metal plates 23 to move up and down at the same time to perform the first strength test on the layered plate. After the first strength test, the detection plate 28 of the middle metal plate 23 is driven to remain stationary, the detection plate 28 of the left metal plate 23 is moved upward, and the detection plate 28 of the right metal plate 23 is moved downward, and the second strength test of the layered plate is performed;

[0051] The first strength test and the second strength test are both to test the strength of the layered plate. If the layered plate breaks, the resistance to the up and down movement of the test plate 28 changes, which will be marked in the PLC system.

[0052] The up and down moving distances of the detection plate 28 in the first strength detection and the second strength detection are both preset values ​​in the PLC system.

[0053] After the above three inspection processes, manual inspection is required to check whether the layered plate is broken. The above three inspections realize the comprehensive coverage inspection of the inner layer of the distribution box, eliminate the blind area of ​​the inspection, and improve the comprehensiveness and accuracy of the inspection. Secondly, the application of the automatic control module makes the inspection process more efficient and convenient, reduces manual operation, reduces human errors, and improves the inspection efficiency. In addition, the PLC system automatically marks unqualified distribution boxes, providing strong support for maintenance work and reducing the difficulty and cost of maintenance.
