[0034] As shown in Figure 6 and Figure 7 As shown, the clamping assembly comprises sliding seats 10, limiting rollers 101, electric rotating rollers 102 and a driving assembly, three sliding seats 10 are slidingly connected to the workbench 1 in a uniform and interval manner along the circumference, the limiting rollers 101 are rotatably connected to the top portions of the right two sliding seats 10, the limiting rollers 101 can realize guiding of the iron core, the material of the outer side of the limiting roller 101 is rubber, the electric rotating roller 102 is vertically installed on the left sliding seat 10, the electric rotating roller 102 can realize driving of the iron core to rotate when the electric rotating roller 102 rotates, the material of the outer side of the electric rotating roller 102 is rubber, and the driving assembly is arranged on the workbench 1, which can realize driving of the sliding seats 10 to move when the driving assembly operates; the driving assembly comprises a stepping motor 103, an arc-shaped shell 104, arc-shaped frames 105, an inner ring gear 106 and a driving gear 107, the arc-shaped shell 104 is fixedly connected to the bottom of the workbench 1, the inner ring gear 106 is rotatably connected to the inner side of the arc-shaped shell 104, three arc-shaped frames 105 are fixedly connected to the inner side of the inner ring gear 106 in a uniform and interval manner along the circumference, the three arc-shaped frames 105 are slidingly connected to the lower portions of the three sliding seats 10 respectively, the arc-shaped frame 105 can realize driving of the sliding seat 10 to move when the arc-shaped frame 105 rotates, the driving gear 107 is rotatably connected to the top left rear side of the workbench 1, the driving gear 107 is engaged with the inner ring gear 106, the stepping motor 103 is installed on the top left rear side of the workbench 1, and the output shaft end of the stepping motor 103 is fixedly connected to the shaft portion of the driving gear 107.

[0035] First, the iron core is placed on the workbench 1, and the iron core is between the limiting roller 101 and the electric roller 81, and then the step motor 103 is started. The step motor 103 drives the driving gear 107 to rotate in the positive direction, the driving gear 107 drives the inner gear 106 to rotate in the positive direction, the inner gear 106 drives the arc-shaped frame 105 to rotate in the positive direction, the arc-shaped frame 105 drives the three sliding seats 10 to move inward, the right two sliding seats 10 drive the limiting roller 101 to move inward, and the left sliding seat 10 drives the electric rotating roller 102 to move inward. When the electric rotating roller 102 and the limiting roller 101 move inward and contact the iron core, the step motor 103 is turned off, the driving gear 107 stops driving the inner gear 106 to rotate in the positive direction, the arc-shaped frame 105 stops driving the sliding seat 10 to move inward, and the limiting roller 101 and the electric rotating roller 102 also stop moving. Then twist the knob 6 to separate from the placing rod 5, put the two coils of wires on the two placing rods 5, move the knob 6 to contact with the placing rod 5, twist the knob 6 to reset to limit the wires, so as to prevent the wires from falling off the placing rod 5. Then pull the head end of the two coils of wires to pass through the tee pipe 8 from below, and make the wires move upward through the electric roller 81 and the guide roller 83 between them. The electric roller 81 and the guide roller 83 are in contact with the wires. Due to the action of the connecting spring 84, the guide roller 83 can closely contact with the wires for guiding. Then pull the head end of one of the wires to pass through the shell 9 and bind the iron core with the four hooks 4. Then start the visual detection module 85 to detect the wires in the shell 9. The electric arc-shaped plate 3 is started in reverse, which drives the wires to reverse. The wires are wound on the iron core in reverse. The hooks 4 and the tee pipe 8 guide the wires in use. At the same time, the electric rotating roller 102 is started to rotate, which drives the iron core to rotate through the two limiting rollers 101. The iron core rotates to make the wires evenly wound. When the wires are wound on the iron core, the electric arc-shaped plate 3 is turned off, which stops the wires from reversing. At the same time, the electric rotating roller 102 is turned off, which stops driving the iron core to rotate. The wires are cut off. The step motor 103 is started in reverse, which drives the driving gear 107 to reverse. The driving gear 107 drives the inner gear 106 to reverse. The inner gear 106 drives the arc-shaped frame 105 to reverse. The arc-shaped frame 105 drives the three sliding seats 10 to move outward to reset. The right two sliding seats 10 drive the two limiting rollers 101 to move outward to reset. The left sliding seat 10 drives the electric rotating roller 102 to move outward to reset. The iron core is released, and the iron core with the wound wires can be taken off from the workbench 1 for subsequent processing. The wires can be continuously wound on the iron core. When the tail end of the wire passes through the visual detection module 85, it means that a coil of wire is almost used up. The visual detection module 85 does not detect the wire, and the visual detection module 85 controls the electric arc-shaped plate 3 to be turned off through the control module. The electric arc-shaped plate 3 stops driving the wires to reverse.Meanwhile the visual inspection module 85 also controls the electric roller 81 to rotate through the control module, the electric roller 81 rotates to drive the guide wire to move upwards through the corresponding guide roller 83, the guide wire moves upwards to the shell 9 and contacts the almost used guide wire, the electric roller 81 is turned off, the guide wire stops moving upwards, the drive motor 932 is started to reverse to drive the spur gear 931 to reverse, the spur gear 931 reverses to drive the left and right racks 93 to move inwards, the racks 93 drive the left and right positioning plates 92 to move inwards, the left and right positioning plates 92 move inwards to contact the two guide wires, the positioning plates 92 position the left and right sides of the two guide wires, the drive motor 932 is turned off, the spur gear 931 stops driving the positioning plates 92 to move through the racks 93, then the front and rear cylinders 94 are started, the front and rear cylinders 94 drive the front and rear heating blocks 95 to move inwards, the front and rear heating blocks 95 move inwards to contact the two guide wires, the cylinder 94 is turned off, the heating block 95 can be started to melt and weld the two guide wires, when the two guide wires are welded together, the heating block 95 is turned off, the cylinder 94 is started to drive the front and rear heating blocks 95 to move outwards to reset, the drive motor 932 is started to drive the spur gear 931 to rotate forward, the spur gear 931 rotates forward to drive the left and right positioning plates 92 to move outwards to reset through the racks 93, the positioning plates 92 reset and are out of contact with the guide wire, the drive motor 932 is turned off, then the electric arc-shaped plate 3 is continuously started to reverse to drive the guide wire to reverse and continue to wind on the iron core, so as to repeat, whenever the guide wire is almost used up, the new guide wire can be automatically connected and welded with the previous guide wire, without manual intervention, so as to improve the efficiency of the guide wire winding.

[0036] Please refer to Figures 8-11As shown, the wire winding device for transformer production further comprises a tensioning assembly installed on the electric arc-shaped plate 3. The tensioning assembly comprises a mounting plate 11, a sliding block 111, a friction assembly, a wire wheel I 117, a wire wheel II 118, a pressure sensor 119, a guide rod 1110 and a return spring 1111. The mounting plate 11 is horizontally fixed on the upper inner side of the electric arc-shaped plate 3. The wire wheel I 117 is rotatably connected to the bottom of the mounting plate 11 in a left-right symmetrical manner. The wire wheel I 117 can guide the wire. The sliding block 111 is slidably connected to the middle of the mounting plate 11. The wire wheel II 118 is rotatably connected to the lower front side of the sliding block 111 in a front-rear symmetrical manner. The guide rod 1110 is slidably connected to the front side of the mounting plate 11. The pressure sensor 119 is installed between the rear end of the guide rod 1110 and the front side of the sliding block 111. The return spring 1111 is connected between the rear side of the guide rod 1110 and the inner side of the mounting plate 11. The friction assembly is arranged between the placement rod 5 and the electric arc-shaped plate 3. When the friction assembly is in operation, the friction assembly can rub the placement rod 5. The friction assembly comprises a rotating shaft 112, a servo motor 113, a circular frame 114, a friction block 115, a friction wheel 116 and a compression spring 1161. The friction wheel 116 is fixedly sleeved on the end of each of the two placement rods 5 which are close to each other. The rotating shaft 112 is rotatably connected to the lower inner side of the electric arc-shaped plate 3 and located between the two placement rods 5. The circular frame 114 is fixedly connected to each of the two ends of the rotating shaft 112. The friction block 115 is rotatably connected to the inner side of each of the two circular frames 114 in a symmetrical manner. The friction block 115 is in contact with the friction wheel 116. The compression spring 1161 is connected between the outer side of the friction block 115 and the inner side of the circular frame 114. The servo motor 113 is installed on the lower inner side of the electric arc-shaped plate 3 and located below the rotating shaft 112. The output shaft of the servo motor 113 is drivingly connected to the rotating shaft 112 through a bevel gear assembly.

[0037] When the pull line head end passes through the hook 4, the pull line head end passes through the right two wire wheels 1117, the two wire wheels 1118 and the left wire wheel 1117 in turn, and then the electric arc-shaped plate 3 reverses to drive the wire to reverse and wind on the iron core. At this time, the placing rod 5 reverses to drive the friction wheel 116 to reverse, and the wire is in a taut state to drive the wire wheel 118 to move forward, the wire wheel 118 moves forward to drive the slider 111 to move forward to the maximum stroke, the slider 111 moves forward to drive the pressure sensor 119 to move forward, the pressure sensor 119 drives the guide rod 1110 to move forward to the maximum stroke, and the reset spring 1111 is compressed. The pressure sensor 119 detects the force of the forward movement of the slider 111, that is, detects the tension of the wire. When the wire appears loose during winding, the wire loses the force limiting the wire wheel 118. Due to the action of the reset spring 1111, the guide rod 1110 moves backward to drive the pressure sensor 119 to move backward, the pressure sensor 119 drives the slider 111 to move backward, the slider 111 drives the wire wheel 118 to move backward, the force of the slider 111 decreases, the pressure value detected by the pressure sensor 119 decreases, the pressure sensor 119 controls the servo motor 113 to start through the control module, the servo motor 113 drives the rotating shaft 112 to rotate clockwise through the bevel gear assembly, the rotating shaft 112 drives the circular frame 114 to rotate clockwise, and the circular frame 114 drives the friction block 115 to rotate clockwise. Due to the action of the compression spring 1161, the friction block 115 rotates clockwise and continuously rubs on the reverse friction wheel 116. The friction of the friction block 115 slows down the reverse speed of the friction wheel 116, and the friction wheel 116 makes the placing rod 5 reverse more slowly. The placing rod 5 makes the wire slowly unwind and wind. Since the wire is slowly released and the reverse speed of the electric arc-shaped plate 3 does not change, the wire is taut and continues to wind on the iron core. The wire taut drives the wire wheel 118 to move forward again, so that the slider 111 drives the guide rod 1110 to move forward to the maximum stroke through the pressure sensor 119, the reset spring 1111 is compressed, the pressure sensor 119 detects the maximum pressure of the forward movement of the slider 111, the pressure sensor 119 controls the servo motor 113 to close through the control module, the rotating shaft 112 stops driving the friction block 115 to rotate clockwise through the circular frame 114, and the friction block 115 stops rubbing the friction wheel 116. Repeat the above process. When the wire appears loose, the wire can be taut and continue to wind on the iron core. When the wire is used up, the wire is out of contact with the wire wheel 118 and the wire wheel 1117. Due to the action of the reset spring 1111, the guide rod 1110 moves backward to reset the slider 111 to move backward to reset through the pressure sensor 119, and the slider 111 drives the wire wheel 118 to move backward to reset. In this way, the wire can be prevented from being wound on the iron core in a loose state to affect the winding effect, thereby ensuring the winding effect of the wire.

[0038] Please refer to Figure 12 As shown, the wire winding device for transformer production further comprises a connecting plate 12, a surplus detector 121 and a warning light 13. The connecting plate 12 is symmetrically fixed on the inner lower part of the electric arc-shaped plate 3, and the surplus detector 121 is installed on the connecting plate 12 on both sides. The surplus detector 121 is composed of a contact plate, an angular velocity sensor and a torsional spring, and corresponds to the placement rod 5. The surplus detector 121 detects the surplus of the wire through the change of the angle. The warning light 13 is installed on the left side of the connecting plate 12 and is electrically connected with the surplus detector 121 through a control module.

[0039] When the wire needs to be placed on the placement rod 5, the surplus detector 121 is first swung to the left to the appropriate position, then the wire is placed on the placement rod 5, and then the surplus detector 121 is loosened. The surplus detector 121 swings to the right and contacts the wire. Then the wire is continuously unwound for use, and the surplus of the wire is continuously reduced. The surplus detector 121 continuously swings to the right with the use of the wire. The surplus detector 121 detects the surplus of the wire. When the surplus detector 121 swings to the original position, it means that the wire is used up. The surplus detector 121 controls the warning light 13 to light up through the control module. The warning light 13 reminds the operator to replace a new roll of wire. The surplus detector 121 can be swung to the left to the appropriate position, and a new roll of wire can be placed on the placement rod 5. The surplus detector 121 is loosened to contact the wire, and the surplus detector 121 continues to detect the surplus of the wire.
