Description

Technical Field

[0001] This utility model relates to the technical field of transformer winding tools, specifically a transformer winding machine. Background Technology

[0002] A transformer coil is a type of coil that is necessary for a transformer to operate. Transformers are classified by the number of phases: Single-phase transformers are used for single-phase loads and three-phase transformer banks. Three-phase transformers are used for stepping up or down voltage in three-phase systems. They are also classified by capacity: Small transformers typically use insulated round copper wire for their coils, while large transformers use insulated flat copper wire. Coils are generally classified into two types: layered and disc-shaped. A layered coil is one where the turns of wire are continuously wound in layers along the axial direction. Each layer is cylindrical, which is to ensure good mechanical strength, resistance to deformation, and ease of winding. A coil consisting of two layers is called a double-layered cylindrical coil; a coil consisting of multiple layers is called a multi-layered cylindrical coil.

[0003] When winding a transformer bobbin, the wire bundle at the starting point cannot be close to the edge of the bobbin due to the steps on the bobbin. Furthermore, after winding, the lead wire is usually pulled out of the bobbin at an angle, which will cause uneven winding of the next winding. This can easily lead to loose winding coils, increased leakage inductance, and deterioration of transformer performance. At the same time, if the wire bundle is not evenly distributed on the outside of the bobbin during the winding process, it will increase the leakage inductance of the transformer. Therefore, a transformer winding machine is proposed. Utility Model Content

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: 1. This utility model uses the piston rod of the first cylinder to drive the first movable seat to reset, thereby causing the baffle on the support column to move upward. The baffle then abuts against the outside of the transformer frame, making the wire harness close to the winding column of the transformer frame, reducing transformer leakage inductance and increasing the winding area. After winding, the piston rod of the first cylinder drives the first movable seat to move downward, causing the baffle to disengage from the outside of the transformer frame. Then, the push rod of the first electric push rod drives the slide to move, thereby moving the baffle to the other end of the transformer frame. Then, the piston rod of the first cylinder drives the first movable seat to move upward, causing the baffle to abut against the outside of the wire harness. This can position the wire harness before it is led out, ensuring that the rear winding wiring is flatter, reducing leakage inductance, and improving transformer performance.

[0014] This invention uses the output shaft of a drive motor to rotate an active synchronous wheel. The active synchronous wheel, through a driven synchronous wheel, drives a positioning guide post to rotate. The positioning guide post, through a guide post, drives the transformer skeleton on the connecting seat to rotate, thereby winding the wire harness around the outside of the transformer skeleton. During the winding process, the push rod of the second electric push rod resets, causing one end of the positioning guide post to move inside the driven synchronous wheel. This, through the guide post, drives the transformer skeleton on the connecting seat to move, enabling uniform winding of the transformer skeleton and preventing leakage inductance during winding, thus ensuring the performance of the transformer.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented.

[0020] Example In the prior art, when winding the transformer frame, the wire harness at the starting point cannot be close to the edge of the frame due to the steps on the frame. Moreover, after the winding is completed, the lead wire is usually pulled out of the frame at an angle, which will cause the next winding to be uneven. This will easily lead to the winding coil being loose, the leakage inductance increasing, and the transformer performance deteriorating. At the same time, if the wire harness is not evenly distributed on the outside of the frame during the winding process, it will increase the leakage inductance of the transformer.

[0021] Please see Figure 1-8 This utility model provides a technical solution: a transformer winding machine, including a fixed frame 1, an auxiliary component is provided on the bottom inner side of the fixed frame 1, and a winding component is provided on the top inner side of the fixed frame 1.

[0022] By setting auxiliary components, transformer leakage inductance can be reduced, winding area can be increased, and the rear winding wiring can be made flatter, thus improving transformer performance. The auxiliary components include a fixed base 7, a gripper shear 8, and a baffle 9. A slide block 2 is slidably connected to the inner bottom of the fixed frame 1. A first cylinder 3 is installed on one side of the slide block 2. The piston rod of the first cylinder 3 is fixedly connected to a first movable base 4. A support column 6 is fixedly connected to the first movable base 4. The fixed base 7 is fixedly connected to one side of the support column 6. The gripper shear 8 is connected to the top of one side of the fixed base 7. The baffle 9 is fixedly connected to the top of the other side of the fixed base 7. A moving component is set on the inner bottom of the fixed frame 1. The moving component includes a first electric push rod 10. The first electric push rod 10 is installed on the inner bottom of the fixed frame 1, and the push rod of the first electric push rod 10 is fixedly connected to the slide block. 2. A first long through groove 5 is provided at the lower front end of the fixing frame 1, and one end of the support column 6 passes through the interior of the first long through groove 5. The piston rod of the first cylinder 3 drives the first moving seat 4 to reset, thereby driving the baffle 9 on the support column 6 to move upward. The baffle 9 then abuts against the outside of the transformer frame 19, so that the wire harness is close to the winding post of the transformer frame 19. After the winding is completed, the piston rod of the first cylinder 3 drives the first moving seat 4 to move downward, so that the baffle 9 is disengaged from the outside of the transformer frame 19. Then, the push rod of the first electric push rod 10 drives the slide 2 to move, thereby driving the baffle 9 to move to the other end of the transformer frame 19. Then, the piston rod of the first cylinder 3 drives the first moving seat 4 to move upward, so that the baffle 9 abuts against the outside of the wire harness, which can position the wire harness before it is led out.

[0023] The winding assembly includes a guide cylinder 15, a guide post 16, and a connecting seat 18. A second cylinder 11 is mounted on the top inner side of the fixing frame 1.

The connecting seat 18 is installed at one end of the guide post 16, and a transformer bobbin is mounted on the connecting seat 18. 19. The piston rod of the second cylinder 11 resets, causing the guide cylinder 15 to move, so that the connecting seat 18 moves to the other end of the second long through groove 17, and the transformer frame 19 moves on the connecting seat 18; the bottom of the mounting seat 13 is provided with an adjustment component on the rear side of the fixing plate 14, and the other end of the bottom of the mounting seat 13 is provided with a drive component; the upper front end of the fixing frame 1 is provided with a second long through groove 17, and the connecting seat 18 passes through the interior of the second long through groove 17; the connecting seat 18 moves inside the second long through groove 17. The solenoid valve of the second cylinder 11 is activated by the switch group, and the piston rod of the second cylinder 11 is reset, which drives the guide cylinder 15 to move, so that the connecting seat 18 moves to the other end of the second long through groove 17, and the transformer frame 19 moves to the top of the gripper scissors 8. Then, the gripper scissors 8 is moved to the outside of one end of the transformer frame 19 by the first electric push rod 10, and then the gripper scissors 8 is moved to the outside of the transformer frame 19 and the outside of the displacement wire harness by the first cylinder 3. At this time, the solenoid valve of the gripper scissors 8 is activated by the switch group, and the gripper scissors 8 can trim the excess wire harness.

[0024] To ensure transformer performance, the adjustment assembly includes a positioning guide post 21, a fixing block 22, and a second electric push rod 23. One end of the guide cylinder 15 is rotatably connected to a driven synchronous wheel 20. One end of the guide post 16 is inserted into the driven synchronous wheel 20. One end of the positioning guide post 21 is slidably connected to the inside of the driven synchronous wheel 20 and fixedly connected to one end of the guide post 16. The fixing block 22 is fixedly connected to the bottom of the mounting base 13. The second electric push rod 23 is mounted on the fixing block 22, and the push rod of the second electric push rod 23 is rotatably connected to the other end of the positioning guide post 21. During the winding process, the push rod of the second electric push rod 23 resets, causing one end of the positioning guide post 21 to move inside the driven synchronous wheel 20. This, in turn, drives the transformer frame 19 on the connecting base 18 to move through the guide post 16, enabling uniform winding of the transformer frame 19 and preventing leakage inductance during winding.

[0025] By setting up a drive assembly, the wire harness can be wound around the outside of the transformer frame 19. The drive assembly includes a drive motor 24 and a drive synchronous pulley 25. The drive motor 24 is installed at the other end of the mounting base 13. The drive synchronous pulley 25 is installed on the output shaft of the drive motor 24. The drive synchronous pulley 25 and the driven synchronous pulley 20 are connected by a synchronous belt. A sliding column is fixedly connected to the outside of the positioning guide post 21. A sliding groove is provided inside the driven synchronous pulley 20. The sliding column is slidably connected inside the sliding groove. The output shaft of the drive motor 24 drives the drive synchronous pulley 25 to rotate. The drive synchronous pulley 25 drives the positioning guide post 21 to rotate through the driven synchronous pulley 20. The positioning guide post 21 drives the transformer frame 19 on the connecting base 18 to rotate through the guide post 16, thereby winding the wire harness around the outside of the transformer frame 19.

[0026] In terms of working principle or structural principle, when winding the transformer bobbin 19, the transformer bobbin 19 is installed on the connecting seat 18, and then one end of the wire harness is first wound onto a pin of the transformer bobbin 19. At this time, the solenoid valve of the first cylinder 3 is activated by the switch group, and the piston rod of the first cylinder 3 drives the first moving seat 4 to reset, thereby driving the baffle 9 on the support column 6 to move upward. The baffle 9 then abuts against the outside of the transformer bobbin 19, so that the wire harness is close to the winding post of the transformer bobbin 19, reducing transformer leakage inductance and increasing the winding area. During winding, the second electric push rod 23 is controlled by the switch group. When the drive motor 24 is started, the output shaft of the drive motor 24 drives the active synchronous wheel 25 to rotate. The active synchronous wheel 25 drives the positioning guide post 21 to rotate through the driven synchronous wheel 20. The positioning guide post 21 drives the transformer skeleton 19 on the connecting seat 18 to rotate through the guide post 16, thereby winding the wire harness around the outside of the transformer skeleton 19. During the winding process, the push rod of the second electric push rod 23 resets and drives one end of the positioning guide post 21 to move inside the driven synchronous wheel 20, thereby driving the transformer skeleton 19 on the connecting seat 18 to move through the guide post 16, so that the transformer skeleton 19 can be wound evenly. After winding is completed, the solenoid valve of the first cylinder 3 is activated by the switch group. The piston rod of the first cylinder 3 drives the first moving seat 4 downward, causing the baffle 9 to disengage from the outside of the transformer frame 19. The push rod of the first electric push rod 10 is reset by the switch group. The push rod of the first electric push rod 10 drives the slide 2 to move, thereby moving the baffle 9 to the other end of the transformer frame 19. Then, the piston rod of the first cylinder 3 drives the first moving seat 4 upward, causing the baffle 9 to abut against the outside of the wire harness. This allows the wire harness to be positioned and led out, ensuring a flatter rear winding and reducing leakage inductance. The controllable baffle 9 can be reset; after the winding is completed, the solenoid valve of the second cylinder 11 is started by controlling the switch group, the piston rod of the second cylinder 11 is reset and drives the guide cylinder 15 to move, so that the connecting seat 18 moves to the other end of the second long through groove 17, and the transformer frame 19 moves to the top of the gripper scissors 8. Then, the gripper scissors 8 is moved to the outside of one end of the transformer frame 19 by the first electric push rod 10, and then the gripper scissors 8 is moved to the outside of the transformer frame 19 and the outside of the displacement wire harness by the first cylinder 3. At this time, the solenoid valve of the gripper scissors 8 is started by controlling the switch group, and the gripper scissors 8 can trim the excess wire harness.
