[0032] See also Figure 6 and Figure 7 As shown, the clamping assembly includes a sliding seat 10, a limiting roller 101, an electric rotating roller 102 and a driving assembly. Three sliding seats 10 are connected to the workbench 1 in a sliding manner at uniform intervals along the circumference. The tops of the two sliding seats 10 on the right are rotatably connected to the limiting roller 101. The limiting roller 101 can guide the iron core. The outer side of the limiting roller 101 is made of rubber. An electric rotating roller 102 is vertically installed on the left sliding seat 10. When the electric rotating roller 102 rotates, the electric rotating roller 102 can drive the iron core to rotate. The outer side of the electric rotating roller 102 is made of rubber.

A stepping motor 103 is installed on the left rear side of the top of the workbench 1, and the output shaft end of the stepping motor 103 is fixedly connected to the shaft of the driving gear 107.

[0033] First, place the iron core on the workbench 1, and make the iron core between the limiting roller 101 and the electric roller 81, then start the stepper motor 103, the stepper motor 103 rotates forward to drive the driving gear 107 to rotate forward, the driving gear 107 rotates forward to drive the inner ring gear 106 to rotate forward, the inner ring gear 106 rotates forward to drive the arc frame 105 to rotate forward, the arc frame 105 rotates forward to drive the three sliding seats 10 to move inward, the two sliding seats 10 on the right side drive the limiting roller 101 to move inward, the sliding seat 10 on the left side 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, turn off the stepper motor 103, the driving gear 107 stops driving the inner ring gear 106 to rotate forward, and the arc frame 105 stops driving the sliding seat 10 to move inward , the limiting roller 101 and the electric rotating roller 102 stop moving, and then twist the knob 6 to rotate and separate from the placement rod 5, put the two rolls of wire on the two placement rods 5 respectively, move the knob 6 to contact the placement rod 5, twist the knob 6 to reset and limit the wire to prevent the wire from falling from the placement rod 5, and then pull the head ends of the two rolls of wire from below into the tee pipe 8, and move the wire upward through the electric roller 81 and the guide roller 83. The electric roller 81 and the guide roller 83 are in contact with the wire. Due to the action of the connecting spring 84, the guide roller 83 can be in close contact with the wire for guiding, and then pull one of the wire heads through the shell 9 and tie it to the iron core with four hooks 4, and then start the visual inspection module 85. The visual inspection module 85 checks the shell 9 is detected, the electric arc plate 3 can be started to reverse, the electric arc plate 3 reverses and drives the wire to reverse, the wire is reversed and wound on the iron core, the hook 4 and the tee pipe 8 guide the wire in use, and at the same time the electric rotating roller 102 is started to rotate, the electric rotating roller 102 drives the iron core to rotate through the two limit rollers 101, the iron core rotates so that the wire is evenly wound, when the wire is reversed and released to be wound on the iron core, the wire drives the placing rod 5 to rotate, when the wire is wound on the iron core, the electric arc plate 3 is closed, the electric arc plate 3 stops the wire reversal, and the electric rotating roller 102 is closed at the same time, the electric rotating roller 102 stops driving the iron core to rotate, the wire is cut off, the stepping motor 103 is started to reverse and drive the driving gear 107 to reverse, the driving gear The reversal of 107 drives the inner gear ring 106 to reverse, and the reversal of the inner gear ring 106 drives the arc frame 105 to reverse, and the reversal of the arc frame 105 drives the three sliding seats 10 to move outward and reset, and the right sliding seat 10 drives the two limit rollers 101 to move outward and reset, and the left sliding seat 10 drives the electric rotating roller 102 to move outward and reset, and the iron core is loosened, and the iron core with the wound wire can be removed from the workbench 1 for subsequent processing, and this is repeated, and the wire 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 roll of wire is almost used up, and the visual detection module 85 does not detect the wire. The visual detection module 85 controls the electric arc plate 3 to close through the control module, and the electric arc plate 3 stops driving the wire to reverse.At the same time, the visual inspection module 85 also controls the rotation of the electric roller 81 through the control module. The rotation of the electric roller 81 drives the wire to move upward through the corresponding guide roller 83. The wire moves upward into the shell 9 and contacts the wire that is about to be used up. The electric roller 81 is turned off, the wire stops moving upward, the drive motor 932 is started to reverse and drive the spur gear 931 to reverse. The spur gear 931 reverses and drives the left and right racks 93 to move inward. The racks 93 drive the left and right positioning plates 92 to move inward. The left and right positioning plates 92 move inward and contact the two wires. The positioning plates 92 position the left and right sides of the two wires. The drive motor 932 is turned off, the spur gear 931 stops driving the positioning plates 92 to move through the rack 93, and then the front and rear cylinders 94 are started. The front and rear cylinders 94 drive the front and rear heating blocks 9 5 moves inward, and the front and rear heating blocks 95 move inward to contact the two wires. The cylinder 94 is closed, and the heating blocks 95 can be started to melt and weld the two wires. When the two wires are welded together, the heating blocks 95 are closed, and the cylinder 94 is started to drive the front and rear heating blocks 95 to move outward and reset. The drive motor 932 is then started to drive the spur gear 931 to rotate forward. The spur gear 931 rotates forward and drives the left and right positioning plates 92 to move outward and reset through the rack 93. The positioning plates 92 reset and disengage from the wires. The drive motor 932 is then turned off, and the electric arc plate 3 is then started to reverse, driving the wires to reverse and continue winding around the iron core. This process is repeated. Whenever the wire is almost used up, a new wire can be automatically connected and welded to the previous wire without manual intervention, thereby improving the efficiency of wire winding.

[0034] See also Figures 8-11As shown, the wire winding device for transformer production also includes a tensioning assembly installed on the electric curved plate 3, the tensioning assembly includes a mounting plate 11, a slider 111, a friction assembly, a wire wheel I 117, a wire wheel II 118, a pressure sensor 119, a guide rod 1110 and a reset spring 1111, the mounting plate 11 is laterally fixed to the upper inner side of the electric curved plate 3, the bottom of the mounting plate 11 is symmetrically connected to two wire wheels I 117 for rotation, the wire wheel I 117 can guide the wire, the middle of the mounting plate 11 is slidably connected with the slider 111, the lower part of the slider 111 is symmetrically connected to the wire wheel II 118 for rotation front and back, the front side of the mounting plate 11 is slidably connected with the guide rod 1110, the pressure sensor 119 is installed between the rear end of the guide rod 1110 and the front side of the slider 111, the reset spring 1111 is connected between the rear side of the guide rod 1110 and the inner side of the mounting plate 11, and a friction assembly is provided between the placement rod 5 and the electric curved plate 3 116, and the servo motor 113 is located below the rotating shaft 112, and the output shaft of the servo motor 113 is connected to the rotating shaft 112 through a bevel gear assembly.

[0035] When the wire end passes through the hook 4, the wire end passes through the two wire wheels Ⅰ117 on the right, between the two wire wheels Ⅱ118 and between the wire wheels Ⅰ117 on the left in sequence, and then the electric arc plate 3 reverses to drive the wire to reverse and wrap around the iron core, the placement rod 5 reverses to drive the friction wheel 116 to reverse, and at the same time, the wire is in a taut state and drives the wire wheel Ⅱ118 to move forward, and the wire wheel Ⅱ118 moves forward and drives the slider 111 to move forward to the maximum stroke, and the slider 111 moves forward and drives the pressure sensor 119 to move forward, and the pressure sensor 119 drives the guide rod 1110 to move forward to At the maximum stroke, the reset spring 1111 is compressed, and the pressure sensor 119 detects the force of the slider 111 moving forward, and also detects the tension of the wire. When the wire becomes loose during the winding process, the wire loses the force to limit the wire wheel II 118. Due to the action of the reset spring 1111, the guide rod 1110 moves backward, driving the pressure sensor 119 to move backward. The pressure sensor 119 drives the slider 111 to move backward, and the slider 111 drives the wire wheel II 118 to move backward. The pressure applied by the slider 111 decreases, and 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 forward through the bevel gear assembly. The rotating shaft 112 rotates forward to drive the circular frame 114 to rotate forward. The circular frame 114 rotates forward to drive the friction block 115 to rotate forward. Due to the action of the compression spring 1161, the friction block 115 rotates forward and continuously rubs against the friction wheel 116 in the reverse direction. The friction of the friction block 115 slows down the reverse speed of the friction wheel 116. The friction wheel 116 makes the placement rod 5 reverse more slowly. The placement rod 5 makes the wire slowly pay out and wind. As the wire is slowly paid out, The speed at which the electric curved plate 3 reverses remains unchanged, causing the wire to remain taut and continue to be wound around the core. This tightening of the wire again drives wire pulley II 118 forward, causing slider 111 to move forward to its maximum travel through pressure sensor 119. Return spring 1111 is compressed, and pressure sensor 119 detects the maximum force exerted by slider 111's forward movement. Pressure sensor 119 controls servo motor 113 via the control module to shut down, stopping shaft 112 from rotating forward through circular frame 114 and driving friction block 115, which then ceases rubbing friction wheel 116. This process repeats itself. Whenever the wire becomes loose, the wire is re-tightened and wound around the core. When all the wire is used up, it loses contact with wire pulley II 118 and wire pulley I 117. Due to the action of return spring 1111, guide rod 1110 moves backward to reset, driving slider 111 backward through pressure sensor 119 to reset. Slider 111 then drives wire pulley II 118 backward to reset. In this way, the wire can be prevented from being loosely wound around the iron core and affecting the winding effect, thereby ensuring the winding effect of the wire.

[0036] See also Figure 12 As shown, the wire winding device for transformer production also includes a connecting plate 12, a remainder detector 121 and a warning light 13. The connecting plate 12 is symmetrically fixed to the front and rear of the lower inner side of the electric arc plate 3. The remainder detector 121 is installed on the front and rear connecting plates 12. The remainder detector 121 is composed of a contact plate, an angular velocity sensor and a torsion spring. The remainder detector 121 corresponds to the placement rod 5. The remainder detector 121 detects the remainder of the wire by changing the angle. A warning light 13 is installed on the left side of the connecting plate 12. The warning light 13 and the remainder detector 121 are electrically connected through a control module.

[0037] When it is necessary to place the wire on the placement rod 5, the remaining amount detector 121 is first pulled to the left to swing to a suitable position, the wire is then placed on the placement rod 5, and the remaining amount detector 121 is released. The remaining amount detector 121 swings to the right to contact the wire. The wire is then continuously released for use, and the remaining amount of the wire is continuously reduced. The remaining amount detector 121 swings to the right as the wire is used. The remaining amount detector 121 detects the remaining amount of the wire. When the remaining amount detector 121 swings to its original position, it indicates that the wire is used up. The remaining amount detector 121 controls the warning light 13 to light up through the control module. The warning light 13 lights up to remind the operator that a new roll of wire is needed. The remaining amount detector 121 can be pulled to the left to swing to a suitable position, a new roll of wire is placed on the placement rod 5, and the remaining amount detector 121 is released to swing to contact the wire. The remaining amount detector 121 continues to detect the remaining amount of the wire. In this way, the operator can be reminded in time to place a new wire on the placement rod 5, thereby not affecting the use of the wire.
