Description

Technical Field

[0001] The invention relates to the technical field of transformer production, and in particular to an automatic wire arrangement and winding machine. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. In the production process of the transformer, a winding machine is required to evenly wind the copper wire on the winding roller. In the prior art, when a copper wire is wound using a winding machine, one end of the copper wire is fixed on a winding roller through a wire arrangement mechanism, and the winding roller rotates rapidly to perform the winding work. However, long-term mechanical movement may cause mechanical fatigue, and the copper wire constantly rubs against the wire arrangement mechanism. If there are defects inside the copper wire itself, these factors may cause the copper wire to break. After the wire breaks, a "flying coil" phenomenon will occur, which can easily cause the copper wire to be entangled in other equipment, causing equipment damage and posing a certain threat to the personal safety of the staff.

When working, the winding roller is sleeved on the outside of the rotating shaft, and the airbag is inflated to increase the friction between the airbag and the winding roller, so that the winding roller can rotate with the rotating shaft to perform the winding work. In addition, due to the tension during winding, the copper wire will drive the guide wheel to rise a certain distance. If the copper wire breaks, the guide wheel will drop and cooperate with the pressure relief mechanism to discharge the air in the airbag.

(2) The present invention provides a movable rod, a trigger rod, a fixed ring 1, a fixed ring 2 and a sealing ball. After the copper wire breaks, the driven rod will drive the movable rod to move downward, so that the trigger rod can press the sealing ball downward, and the gas can be automatically discharged. The support seat supports the winding roller. Even if the shaft continues to rotate, it is difficult to drive the winding roller to rotate, thereby reducing the negative impact caused by the copper wire breakage.

A pressure relief mechanism is provided between the driven rod 5 and the vertical pipe 14. When the copper wire breaks, the pressure relief mechanism is triggered to work, and the air in the airbag 7 is discharged. The external plate 8 is snap-fitted to the frame 1 through a buckle. A notch is provided on the side wall of the frame 1, and the driven rod 5 is slidably connected in the notch. First, the unwound winding roller 3 is sleeved on the rotating shaft 2, and one end of the copper wire passes through the bottom of the guide wheel 606 and is fixed to the winding roller 3, and then the external plate 8 is fixed to the frame 1, so that the fixed pipe 10 is aligned with the air intake. The air inlet pipe 11 is connected with the fixed pipe 10 by a rotating sealed connection so that the air inlet pipe 11 can rotate freely, and the inflation pipe 15 is connected to the external air source to inflate the airbag 7. After the airbag 7 is expanded, it is in close contact with the winding roller 3, increasing the friction between the airbag 7 and the winding roller 3. Then the rotating shaft 2 rotates to drive the winding roller 3 to rotate for winding. If the copper wire breaks, the pressure relief mechanism will automatically discharge the air in the airbag 7. At this time, the airbag 7 is no longer in close contact with the winding roller 3, and the winding roller 3 will gradually stop rotating to avoid the "flying roll" phenomenon.

[0018] See also Figure 1 , Figure 3 and Figure 5The pressure relief mechanism includes an L-shaped movable rod 16, one end of which is fixedly connected to the driven rod 5, and the other end passes through the top of the vertical tube 14 and is connected to the trigger rod 17. A fixing ring 18 and a fixing ring 2 19 are fixed in the vertical tube 14. The fixing ring 18 is located above the fixing ring 2 19. A spring 20 is connected to the side wall of the fixing ring 2 19 close to the fixing ring 18. A sealing ball 21 is connected to one end of the spring 20. A hole is provided at the central axis of the fixing ring 18, and the diameter of the sealing ball 21 is larger than the diameter of the hole. The trigger rod 17 passes through the hole and is arranged, and its diameter is smaller than In the hole diameter, when the driven rod 5 is at the lowest point of its moving path, the trigger rod 17 is at the lowest point of its moving path, and the trigger rod 17 pushes the sealing ball 21 to squeeze the spring 20, then the sealing ball 21 is separated from the hole, and a semicircular opening is provided on the support seat 4, and the semicircular opening is coaxially arranged with the rotating shaft 2; before the winding starts, after the winding roller 3 is set and fixed with the copper wire, at this time, the guide wheel 606 is at the lowest point of its moving path, then the driven rod 5 is at the lowest point of its moving path, then the trigger rod 17 is at the lowest point of its moving path, then the trigger rod 17 pushes the sealing ball 21 to squeeze the spring 20, then the sealing ball 21 is separated from the hole, and the support seat 4 is provided with a semicircular opening, and the semicircular opening is coaxially arranged with the rotating shaft 2; before the winding starts, after the winding roller 3 is set and fixed with the copper wire, at this time, the guide wheel 606 is at the lowest point of its moving path, then the driven rod 5 is at the lowest point of its moving path, then the trigger rod 17 is at the lowest point of its moving path, then the trigger rod 17 pushes the sealing ball 21 to squeeze The spring 20 and the sealing ball 21 are separated from the hole. At this time, when the air is inflated through the inflation tube 15, the airflow impacts the sealing ball 21 and continues to squeeze the spring 20, which slightly increases the size of the squeezing spring 20. After the airbag 7 is full, the inflation is stopped, and then the driving source 1 (not shown) is used to drive the rotating shaft 2 to rotate and drive the winding roller 3 to rotate to perform the winding work; when winding, the copper wire will pass under the guide wheel 606. Due to the tension, the guide wheel 606 will be lifted by the copper wire for a distance. At this time, the driven rod 5 rises and drives the trigger rod 17 to rise, and the elastic force of the spring 20 to restore the deformation drives the sealing ball 21 to rise and seal the solid The hole in the fixed ring 18 is formed. During normal winding, the trigger rod 17 will not contact the sealing ball 21. The airbag 7 is filled with gas. Under the action of the spring 20, the sealing ball 21 will seal the bottom of the fixed ring 18, and no gas leakage will occur. When the copper wire breaks, the guide wheel 606 loses its support and descends, driving the driven rod 5, the movable rod 16 and the trigger rod 17 to descend. The trigger rod 17 presses down the sealing ball 21, and the gas in the airbag 7 is automatically discharged. The friction between the airbag 7 and the winding roller 3 is reduced, and the support seat 4 supports the winding roller 3, and the winding roller 3 gradually stops rotating.

[0019] See also Figure 1 and Figure 4A guide groove is provided on the bottom wall of the frame 1, and a guide block 601 is slidably connected in the guide groove. A threaded hole is provided on the guide block 601, and a reciprocating screw 602 is threadedly connected in the threaded hole. Both ends of the reciprocating screw 602 are rotatably mounted on the side wall of the frame 1, and a connecting rod 603 is fixed on the guide block 601. One end of the connecting rod 603 is fixedly connected to a mounting frame 604, and a guide roller 609 is rotatably mounted on the mounting frame 604, and the guide roller 609 is located below the guide wheel 606; when winding, the reciprocating screw 602 rotates, thereby causing the guide block 601 to reciprocate, and the mounting frame 604 is driven to reciprocate by the connecting rod 603, so that the copper wire is evenly arranged on the winding roller 3.

[0020] The working principle of the present invention is as follows: first, the unwound winding roller 3 is mounted on the rotating shaft 2, one end of the copper wire passes through the bottom of the guide wheel 606 and is fixed to the winding roller 3, and then the external plate 8 is fixed to the frame 1, so that the fixed pipe 10 is connected to the air inlet pipe 11, and the air inlet pipe 11 and the fixed pipe 10 are connected in a rotating sealed manner so that the air inlet pipe 11 can rotate freely, and the inflation pipe 15 is connected to the external air source (not shown) to inflate the airbag 7. During inflation, the air pressure pushes the sealing ball 21 down, and the gas passes through the fixing ring 18, the fixing ring 29, the fixing pipe 10, the air inlet pipe 11 and the branch pipe 13 in turn to enter the airbag 7, and the airbag 7 is inflated and connected to the winding roller. 3 is in close contact, increasing the friction between the airbag 7 and the winding roller 3. After the inflation is completed, the air supply is stopped. Under the action of the spring 20, the sealing ball 21 blocks the through hole of the fixing ring 18 to prevent gas leakage. Then, the driving source 1 (not shown) is used to drive the rotating shaft 2 to rotate and drive the winding roller 3 to rotate for winding. At the same time, the reciprocating screw 602 of the driving source 2 (not shown) rotates, so that the guide block 601 moves back and forth. The connecting rod 603 drives the mounting frame 604 to move back and forth, and the copper wire is evenly arranged on the winding roller 3. It is worth mentioning that the external air source can be an air pump, and the driving source 1 and the driving source 2 can both use conventional motors; When winding, the copper wire will pass under the guide wheel 606. Due to the effect of tension, the guide wheel 606 will be lifted up a distance by the copper wire. During normal winding, the trigger rod 17 will not contact the sealing ball 21. When the copper wire breaks, the guide wheel 606 loses support and descends, driving the driven rod 5, the movable rod 16 and the trigger rod 17 to descend. The trigger rod 17 presses down the sealing ball 21, and the gas in the airbag 7 is automatically discharged. The friction between the airbag 7 and the winding roller 3 is reduced, and the support seat 4 supports the winding roller 3, and the winding roller 3 gradually stops rotating to avoid the "flying roll" phenomenon. Even if the operator fails to shut down the equipment in time, the winding roller 3 will not continue to rotate, thereby avoiding the phenomenon of copper wire entanglement with the equipment and improving safety performance.

[0021] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
