Description

Technical Field

[0001] The present invention relates to the technical field of high voltage coil winding, and in particular to a coil winding device and method for transformer processing. Background Art

[0002] Transformer coil is a kind of coil, which is needed inside the transformer to operate. According to the number of phases: single-phase transformer: used for single-phase loads and three-phase transformer groups, three-phase transformer: used for voltage increase and decrease in three-phase systems. According to capacity: small transformer coils are generally made of insulated round copper wire, while large transformers use flat copper wire with an insulating layer.

[0003] The transformer coil is wound into a complete coil by rotating the coil core and then winding the wire on the surface of the coil core. However, the wire wound on the coil will have a slight slack. The looser the winding is, the fewer layers there are.

[0019] A method for winding a coil for transformer processing, which is applicable to the above-mentioned coil winding device for transformer processing, comprises the following steps:

[0020] Step 1: Start the motor to drive gear 1 to rotate, gear 1 synchronously drives gear 2 and gear 3 to rotate, gear 2 rotates to drive shaft 1, box body, bidirectional screw, clamping plate and coil core to rotate, the coil core rotates to pull the wire between the straightening groove and the clamping block to wrap around its outer surface;

[0021] Step 2: Gear 3 drives the reciprocating screw 1 to rotate so that the moving plate 1 drives the slider to move inside the slide slot. The movement of the moving plate 1 will synchronously drive the straightening slot and the clamping block to move, so that the wire follows the movement, driving the wire to move so that the wire is evenly wrapped around the outside of the coil core during the winding process. After moving a certain distance, gear 4 meshes with rack 3. If it continues to move, gear 4 drives the double-stage reciprocating threaded rod 2 to rotate, so that the two moving plates 3 drive the clamping blocks to approach and clamp the wire from top to bottom;

[0022] Step 3: The coil core that continues to be wound will continue to pull the wire, and the wire will pull the clamping block holding the wire to move toward the coil core. The clamping block pulls the C-frame and the slide plate to move along the guide rod 1 and squeeze the spring. The spring increases the tension between the clamping block and the coil core. The higher the tension of the wire, the loose wire on the coil core will be close to the coil core. When the wire on the coil core can no longer be tightened by the spring, it proves that the wire on the coil core is already very close, so the spring will continue to be pulled and compressed, causing the clamping block, the two-stage reciprocating threaded rod 2 and the one-way gear 1 to move with it.

[0023] Step 4: One-way gear 1 meshes with rack 2. The meshing direction of one-way gear 1 and rack 2 satisfies the direction of rotation of one-way gear 1 driving two-stage reciprocating threaded rod 2. Therefore, two-stage reciprocating threaded rod 2 causes two moving plates 3 to drive the clamping blocks away from each other. Because of the push of the spring, when the two clamping blocks release their clamping of the line, the spring will immediately push the clamping blocks back and forth, so that one side of the slide plate contacts the limit block.

[0024] Step 5: The coil core continues to wind the wire. When the moving plate 1 is about to move to the wire tail of the reciprocating screw 1, the one-way gear 2 meshes with the rack 1. The moving meshing direction of the one-way gear 2 satisfies the one-way gear 2 to drive the reciprocating screw 2 to rotate, so that the moving plate 4 drives the rack 2 to move. The movement of the rack 2 increases the distance that the spring is compressed when the second layer is wound, so that the pulling force of the second layer of wire becomes larger, thereby making the multiple layers of wires close together.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention installs a rotating winding mechanism to drive the coil core to rotate, and the wire is wound around the outside of the coil core.

[0027] 2. The present invention installs a coil fixing mechanism and drives the bidirectional screw to rotate by rotating the rotating head to make the clamping plate move closer or farther away. When it moves away, it squeezes the inner wall of the coil core, and when it moves closer, it releases the squeezing of the coil core and makes the coil core easy to take out.

[0028] 3. The present invention installs a moving mechanism to drive the wire to move during the winding process, thereby changing the winding position of the wire and making the wire evenly distributed on the surface of the coil core.

[0029] 4. The present invention installs a tightening mechanism to clamp and limit the wire during the winding process, thereby increasing the tension between the wire and the coil core, so that the loose wire on the surface of the coil core is tightened, thereby increasing the tightness of the wire wound on the surface of the coil core and the number of winding layers, and increasing the pulling force as the number of layers increases, thereby reducing the gap between the multiple layers of wire and improving the quality of the coil.

[0055] The rack three 515 can be provided with a plurality of racks as required, and the plurality of racks can be provided so as to tighten the wire multiple times during the winding of a layer, thereby ensuring the tightness and number of layers of the wire winding;

[0056] The tightening mechanism 5 clamps and limits the wire during the winding process, thereby increasing the tension between the wire and the coil core, thereby tightening the loose wire on the surface of the coil core, thereby increasing the tightness of the wire wound on the surface of the coil core and the number of winding layers, and increasing the pulling force as the number of layers increases, thereby reducing the gap between the multiple layers of wire and improving the quality of the coil.

[0057] The driving mechanism 6 includes a motor 61 fixed to one side of the support frame 1, and a gear 1 62 is fixed to one end of the output shaft of the motor 61. One side of the gear 1 62 is meshed with the gear 2 22, and the other side of the gear 1 62 is meshed with the gear 3 42.

[0058] A method for winding a coil for transformer processing, which is applicable to the above-mentioned coil winding device for transformer processing, comprises the following steps:

[0059] Step 1: Start the motor 61 to drive the gear 1 62 to rotate, the gear 1 62 synchronously drives the gear 2 22 and the gear 3 42 to rotate, the gear 2 22 rotates to drive the shaft 1 21, the box body 31, the bidirectional screw 32, the clamping plate 34 and the coil core 37 to rotate, the coil core 37 rotates to pull the wire sleeved between the straightening groove 59 and the clamping block 512 to wrap around its outer surface;

[0060] Step 2: Gear 3 42 drives the reciprocating screw 1 41 to rotate so that the moving plate 1 47 drives the slider 46 to move inside the slide slot 44. The movement of the moving plate 1 47 will synchronously drive the straightening slot 59 and the clamping block 512 to move, so that the wire follows the movement, driving the wire to move so that the wire is evenly wrapped around the outside of the coil core 37 during the winding process. After moving a certain distance, gear 4 518 meshes with rack 3 515. If it continues to move, gear 4 518 drives the double-stage reciprocating threaded rod 2 516 to rotate, so that the two moving plates 3 511 drive the clamping blocks 512 to approach and clamp the wire from top to bottom.

[0061] Step 3: The coil core 37 that continues to be wound will continue to pull the wire, and the wire will pull the clamping block 512 and other structures that clamp the wire to move toward the coil core 37. The clamping block 512 pulls the C-frame 526 and the slide plate 55 to move along the guide rod 1 52 and squeeze the spring 54. The spring 54 increases the tension between the clamping block 512 and the coil core 37. The higher the tension of the wire, the loose wire on the coil core 37 will be close to the coil core 37. When the wire on the coil core 37 can no longer be tightened by the spring 54, it proves that the wire on the coil core 37 is already very close, so the spring 54 will continue to be pulled and compressed, causing the clamping block 512, the two-stage reciprocating threaded rod 2 516 and the one-way gear 1 517 and other structures to move accordingly.

[0062] Step 4: The one-way gear 1 517 meshes with the rack 2 523. The meshing direction of the one-way gear 1 517 and the rack 2 523 satisfies the direction of rotation of the one-way gear 1 517 driving the double-section reciprocating threaded rod 2 516. Therefore, the double-section reciprocating threaded rod 2 516 causes the two moving plates 3 511 to drive the clamping blocks 512 away from each other. Because of the push of the spring 54, when the two clamping blocks 512 release their clamping of the line, the spring 54 will immediately push the clamping blocks 512 and other structures to return to their original positions, so that one side of the slide plate 55 contacts the limit block 53.

[0063] Step 5: The coil core 37 continues to wind the wire. When the movable plate 47 is about to move to the wire tail of the reciprocating screw 41, the one-way gear 520 engages with the rack 525. The moving meshing direction of the one-way gear 520 satisfies the one-way gear 520 to drive the reciprocating screw 519 to rotate, so that the movable plate 4 521 drives the rack 2 523 to move. The movement of the rack 2 523 increases the compression distance of the spring 54 when the second layer is wound, thereby increasing the pulling force of the second layer of wire, thereby making the multiple layers of wires close together.

[0064] Working principle:

[0065] The starting motor 61 drives the gear 1 62 to rotate, and the gear 1 62 synchronously drives the gear 2 22 and the gear 3 42 to rotate. The rotation of the gear 22 drives the rotating shaft 1 21, the box body 31, the bidirectional screw 32, the clamping plate 34 and the coil core 37 to rotate. The coil core 37 rotates and pulls the wire set between the straightening groove 59 and the clamping block 512 to be wound around its outer surface. The wire entering from the outside will pass through the straightening groove 59 and will be straightened by the straightening groove 59 when passing through, so as to ensure that the wire wound on the coil core 37 is arranged neatly and evenly. According to the material of the wire, the double-section reciprocating threaded rod 1 513 is driven to rotate through the rotating head 2 514, so that the two movable plates 2 57 drive the tensioning block 58 to move away from or close to each other, thereby increasing or reducing the friction force on the wire and increasing or reducing the tension of the wire.

[0066] The gear 3 42 drives the reciprocating screw 41 to rotate so that the moving plate 47 drives the slider 46 to move inside the slide slot 44. The movement of the moving plate 47 will synchronously drive the straightening slot 59 and the clamping block 512 to move, so that the wire follows the movement. Driving the wire to move can evenly wrap the wire around the outside of the coil core 37 during the winding process. After moving a certain distance, the gear 4 518 meshes with the rack 3 515. If it continues to move, the gear 4 518 drives the double-stage reciprocating threaded rod 2 516 to rotate, so that the two moving plates 3 511 drive the clamping blocks 512 to approach and clamp the wire from top to bottom, and the coil core 37 that continues to be wound. 7 will continue to pull the wire, and the wire will pull the clamping block 512 and other structures holding the wire to move toward the coil core 37. The clamping block 512 will pull the C-frame 526 and the slide plate 55 to move along the guide rod 52 and squeeze the spring 54. The spring 54 increases the tension between the clamping block 512 and the coil core 37. The increased tension of the wire will make the loose wire on the coil core 37 close to the coil core 37. When the wire on the coil core 37 can no longer be tightened by the spring 54, it proves that the wire on the coil core 37 is already very close, so the spring 54 will continue to be pulled and compressed, so that the clamping block 51 2. The double-section reciprocating threaded rod 2 516 and the one-way gear 1 517 and other structures follow the movement, and then the one-way gear 1 517 meshes with the rack 2 523. The meshing direction of the one-way gear 1 517 and the rack 2 523 satisfies the direction of the one-way gear 1 517 driving the double-section reciprocating threaded rod 2 516 to rotate. Therefore, the double-section reciprocating threaded rod 2 516 causes the two moving plates 3 511 to drive the clamping blocks 512 away from each other. Because of the push of the spring 54, when the two clamping blocks 512 relax their clamping of the line, the spring 54 will immediately push the clamping blocks 512 and other structures to return to their original positions, so that the slide plate 55 One side contacts with the limit block 53, and the coil core 37 continues to wind the wire. When the movable plate 47 is about to move to the wire tail of the reciprocating screw 41, the one-way gear 520 engages with the rack 525. The moving meshing direction of the one-way gear 520 satisfies the one-way gear 520 to drive the reciprocating screw 519 to rotate, so that the movable plate 4 521 drives the rack 2 523 to move. The movement of the rack 2 523 can increase the compression distance of the spring 54 when the second layer is wound, increase the pulling force on the second layer of wire, make the multiple layers close together, reduce the gap between the multiple layers of wire, and improve the tightness of the line winding.

7. A method for winding a coil for transformer processing, which is applicable to the coil winding device for transformer processing as claimed in claim 6, characterized in that: The following steps are involved: Step 1: starting the motor (61) to drive the gear 1 (62) to rotate, the gear 1 (62) synchronously drives the gear 2 (22) and the gear 3 (42) to rotate, the gear 2 (22) rotates to drive the rotating shaft 1 (21), the box body (31), the bidirectional screw (32), the clamping plate (34) and the coil core (37) to rotate, and the coil core (37) rotates to pull the wire sleeved between the straightening groove (59) and the clamping block (512) to be wound around its outer surface; Step 2: Gear 3 (42) drives the reciprocating screw 1 (41) to rotate, so that the moving plate 1 (47) drives the slider (46) to move inside the slide groove (44). The movement of the moving plate 1 (47) will synchronously drive the straightening groove (59) and the clamping block (512) to move, so that the wire follows the movement, driving the wire to move so that the wire is evenly wrapped around the outside of the coil core (37) during the winding process. After moving a certain distance, gear 4 (518) meshes with rack 3 (515). If the movement continues, gear 4 (518) drives the double-stage reciprocating threaded rod 2 (516) to rotate, so that the two moving plates 3 (511) drive the clamping blocks (512) to approach and clamp the wire from top to bottom; Step 3: The coil core (37) that continues to be wound will continue to pull the wire, and the wire will pull the clamping block (512) that clamps the wire to move toward the coil core (37). The clamping block (512) pulls the C-shaped frame (526) and the slide plate (55) along the guide rod (52) and compresses the spring (54). The spring (54) increases the tension between the clamping block (512) and the coil core (37). The increased tension of the wire will make the loose wire on the coil core (37) close to the coil core (37). When the wire on the coil core (37) can no longer be tightened by the spring (54), it proves that the wire on the coil core (37) is already very close, so the spring (54) will continue to be pulled and compressed, causing the clamping block (512), the two-stage reciprocating threaded rod (516) and the one-way gear (517) to move accordingly. Step 4: The one-way gear 1 (517) meshes with the rack 2 (523). The meshing direction of the one-way gear 1 (517) and the rack 2 (523) satisfies the direction of rotation of the one-way gear 1 (517) to drive the double-section reciprocating threaded rod 2 (516). Therefore, the double-section reciprocating threaded rod 2 (516) causes the two moving plates 3 (511) to drive the clamping blocks (512) away from each other. Because of the push of the spring (54), when the two clamping blocks (512) release their clamping of the line, the spring (54) will immediately push the clamping blocks (512) back to their original position, so that one side of the slide plate (55) contacts the limit block (53). Step 5: The coil core (37) continues to wind the wire. When the movable plate 1 (47) is about to move to the wire tail of the reciprocating screw 1 (41), the one-way gear 2 (520) meshes with the rack 1 (525). The moving meshing direction of the one-way gear 2 (520) satisfies the one-way gear 2 (520) to drive the reciprocating screw 2 (519) to rotate, so that the movable plate 4 (521) drives the rack 2 (523) to move. The movement of the rack 2 (523) increases the distance that the spring (54) is compressed when the second layer is wound, so that the pulling force of the second layer of wire increases, thereby making the multiple layers of wire stick together.
