Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 7 shown, in the embodiment of the present invention, an automatic copper wire diameter measuring device for a photovoltaic transformer includes a workbench 1. A winding roller 2 is installed on the top of the workbench 1. Diameter gauges 3 are arranged on both sides of the winding roller 2, and the two diameter gauges 3 are rotatably installed on one side of the workbench 1;

[0032] A heating box 4 is arranged on one side of the winding roller 2. The top of the heating box 4 is hinged with a top cover 5. Two first flattening rollers 7 are arranged inside the heating box 4, and the two first flattening rollers 7 are symmetrically distributed. A first mounting base 8 is installed at the bottom of one of the first flattening rollers 7, and the first mounting base 8 is embedded inside the heating box 4. The other first flattening roller 7 is installed at the bottom end of the top cover 5.

[0033] Existing: CN222298775U discloses an automatic copper wire diameter measuring device. The workbench 1, winding roller 2, and diameter gauge 3 proposed in this application document are disclosed in this patent, and these technical means will not be elaborated one by one here;

[0034] When measuring the diameter of the copper wire, first open the top cover 5, place the copper wire in the heating box 4, make one end of the copper wire pass through the two first flattening rollers 7, and pass by one side of the winding roller 2, and finally install it on the diameter gauge 3;

[0035] After installation, the copper wire is stretched and unfolded by rotating the diameter gauge 3. During the movement, the top and bottom ends of the copper wire are in contact with the two first smoothing rollers 7, which helps to reduce the curvature of the copper wire and keep it in a straight line state through the winding roller 2, thereby ensuring the measurement accuracy.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, second smoothing rollers 9 are disposed on both sides of the interior of the heating box 4 , and second mounting seats 10 are mounted on one side of the two second smoothing rollers 9 , and the two second mounting seats 10 are both disposed inside the heating box 4 .

[0037] When measuring the diameter of the copper wire, the two sides of the copper wire are in contact with the two second smoothing rollers 9, which can not only reduce the curvature of the copper wire, but also reduce the jitter of the copper wire caused by mechanical vibration or airflow during movement, so that the copper wire remains stable in the diameter gauge 3, and the measurement accuracy and stability are improved;

[0038] The two second smoothing rollers 9 cooperate with the first smoothing roller 7 to contact the left and right sides and the top and bottom ends of the copper wire, and can apply pressure to the copper wire from multiple directions at the same time, completely eliminating the bending and twisting of the copper wire.

[0039] like Figure 7 As shown, springs 11 are installed inside the two second mounting seats 10 and the first mounting seat 8 .

[0040] The two first smoothing rollers 7 and the second smoothing roller 9 are made elastic, and the pressure can be automatically adjusted according to the diameter and material of the copper wire, so as to avoid scratches or deformation of the surface of the copper wire due to excessive pressure.

[0041] like Figure 4 and Figure 5 As shown, the inner walls of the two second mounting seats 10 are both threadedly connected with third threaded rods 31, and a rotating block 22 is fixedly installed at one end of one of the third threaded rods 31, and the rotating block 22 is arranged on one side of the heating box 4;

[0042] The two third threaded rods 31 are both connected to the second rotating shaft 20 through a pulley set 21 at the bottom, one end of the two second rotating shafts 20 is fixedly connected to the second bevel gear 19, the bottom ends of the two second bevel gears 19 are meshed with the first bevel gear 18, the bottom ends of the two first bevel gears 18 are fixedly installed with the first rotating shaft 17, the bottom ends of the two first rotating shafts 17 are fixedly connected with the second gear 16, one side of the two second gears 16 are meshed with the second rack plate 15, one side of the two second rack plates 15 are fixedly installed with the first rack plate 14, the two first rack plates 14 are meshed with the first gear 13, and the first gear 13 is rotatably installed inside the heating box 4.

[0043] When it is necessary to adjust the distance between the two second flattening rollers 9, first rotate the rotating block 22. The rotation of the rotating block 22 drives the rotation of the third threaded rod 31. The rotation of the third threaded rod 31 drives the rotation of the second rotating shaft 20 through the pulley group 21. The rotation of the second rotating shaft 20 drives the rotation of the second bevel gear 19. The rotation of the second bevel gear 19 drives the rotation of the first bevel gear 18. The rotation of the first bevel gear 18 drives the rotation of the first rotating shaft 17. The rotation of the first rotating shaft 17 drives the rotation of the second gear 16. The rotation of the second gear 16 drives the movement of the second rack plate 15. The movement of the second rack plate 15 drives the movement of the first rack plate 14. The movement of the first rack plate 14 drives the rotation of the first gear 13, so that the two first rack plates 14 move synchronously, and thus the two second flattening rollers 9 move simultaneously for adjustment.

[0044] As Figure 5 and Figure 7 shown, a first threaded rod 12 is fixedly installed at the top of the first gear 13, and the first threaded rod 12 is embedded in the inner wall of the first mounting seat 8.

[0045] When adjusting the distance between the two second flattening rollers 9, the rotation of the first gear 13 drives the rotation of the first threaded rod 12. The rotation of the first threaded rod 12 drives the movement of the first mounting seat 8. The movement of the first mounting seat 8 drives the movement of the first flattening roller 7 to change the distance between the two first flattening rollers 7, adapting to copper wires of different diameters and improving the adaptability of the device.

[0046] As Figure 4 shown, an electric heating wire 6 is installed inside the heating box 4.

[0047] When measuring the diameter of the copper wire, the inside of the heating box 4 can be heated by the electric heating wire 6. Since the outer wall of the copper wire usually has an insulating layer, when the copper wire passes through the heating box 4, it is heated to make it softer and easier to be flattened by the first flattening roller 7 and the second flattening roller 9.

[0048] As Figure 4 shown, an air pump 28 is arranged inside the heating box 4. The output end of the air pump 28 is connected to an air pipe 29, and the air pipes 29 are evenly distributed.

[0049] When measuring the diameter of the copper wire, start the air pump 28, blow air into the heating box 4 through the air pipe 29, and perform hot air heating in cooperation with the electric heating wire 6 to avoid local overheating and protect the insulating layer.

[0050] As Figure 4 and Figure 5 shown, a bearing plate 23 is arranged inside the heating box 4, and a fixing seat 24 is fixedly connected to the bottom end of the bearing plate 23.

[0051] When measuring the diameter of the copper wire, placing the copper wire inside the bearing plate 23 helps to guide it, reduce the measurement error caused by deviation, and thus significantly improve the measurement accuracy and stability of the winding roller 2.

[0052] As Figure 5 and Figure 6 shown, a second threaded rod 25 is threadedly connected to the bottom of the fixed seat 24. The bottom end of the second threaded rod 25 is fixedly installed with a third gear 26. One side of the third gear 26 is meshed and connected with a third rack plate 27. The third rack plate 27 is fixedly installed at one end of one of the first rack plates 14.

[0053] When adjusting the distance between the two first flattening rollers 7 and the second flattening roller 9, the movement of the first rack plate 14 drives the movement of the third rack plate 27. The movement of the third rack plate 27 drives the rotation of the third gear 26. The rotation of the third gear 26 drives the rotation of the second threaded rod 25. The rotation of the second threaded rod 25 drives the movement of the fixed seat 24, causing the fixed seat 24 to move up and down, facilitating guiding copper wires of different diameters.

[0054] As Figures 1 to 4 shown, windshields 30 are fixedly installed on both sides of the heating box 4 and the top cover 5, and the windshields 30 are evenly distributed.

[0055] The windshield 30 is elastically arranged;

[0056] One end of the windshield 30 close to the top cover 5 is fixedly connected to the top cover 5, and one end of the windshield 30 close to the heating box 4 is fixedly connected to the heating box 4;

[0057] Due to the elastic potential energy of the windshield 30 itself, when installing the copper wire, the copper wire can be located between two groups of windshields 30. The windshields 30 block the gap between the copper wire and the heating box 4 and the top cover 5, so that the inside of the heating box 4 is as sealed as possible, reducing the loss of hot air.

[0058] Working principle and usage process:

[0059] When measuring the diameter of the copper wire, first open the top cover 5, place the copper wire in the heating box 4 so that it is on top of the bearing plate 23, then pass one end of the copper wire through the gap between the two first flattening rollers 7 and the second flattening roller 9, pull it out through one side of the winding roller 2, and finally install it on the diameter measuring instrument 3.

[0060] During installation, adjust the distance between the two first flattening rollers 7 and the second flattening roller 9 according to the diameter of the copper wire. Rotate the rotating block 22. The rotation of the rotating block 22 drives the rotation of the third threaded rod 31. The rotation of the third threaded rod 31 drives the rotation of the second rotating shaft 20 through the pulley group 21. The rotation of the second rotating shaft 20 drives the rotation of the second bevel gear 19. The rotation of the second bevel gear 19 drives the rotation of the first bevel gear 18. The rotation of the first bevel gear 18 drives the rotation of the first rotating shaft 17. The rotation of the first rotating shaft 17 drives the rotation of the second gear 16. The rotation of the second gear 16 drives the movement of the second rack plate 15. The movement of the second rack plate 15 drives the movement of the first rack plate 14. The movement of the first rack plate 14 drives the rotation of the first gear 13. The rotation of the first gear 13 drives the rotation of the first threaded rod 12. The rotation of the first threaded rod 12 drives the movement of the first mounting seat 8. The movement of the first mounting seat 8 drives the movement of the first flattening roller 7 to change the distance between the two first flattening rollers 7;

[0061] At the same time, the movement of the first gear 13 drives the movement of another first rack plate 14, so that the two second flattening rollers 9 move simultaneously for adjustment;

[0062] After adjusting the distance between the two first flattening rollers 7 and the second flattening roller 9, close the top cover 5. Then, rotate the diameter gauge 3 to stretch and unfold the copper wire. At the same time, heat the inside of the heating box 4 through the electric heating wire 6 and start the air pump 28 to blow air into the heating box 4. When the copper wire moves, its top and bottom contact the two first flattening rollers 7, and both sides contact the two second flattening rollers 9, so that the copper wire passes through the winding roller 2 in a straight state for diameter measurement.

[0063] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
