Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0044] In this embodiment:

[0045] Reference Figure 1-2 As shown, a preferred embodiment of the present invention is provided.

[0046] The transformer winding device of this embodiment includes a processing platform 1, on which a feeding assembly 2, a winding assembly 3 and a feeding guide rail 4 are respectively arranged, and the feeding assembly 2 is transported to the winding assembly 3 along the X direction through the feeding guide rail 4 for winding operation;

[0047] The feeding assembly 2 includes a guide plate 21, on which a stand 22 is mounted, on which a switching plate 25 movable along the Z direction and a plurality of material trays 28 are mounted, respectively, and the switching plate 25 is used to switch the plurality of material trays 28 to sink and perform material discharging and material cutting operations;

[0048] The winding assembly 3 includes a guide plate 31, on which a positioning plate 32 is movably mounted along the Y direction, a rotating seat 321 is mounted on the rotating shaft of the positioning plate 32, and a transformer 34 and a locking member 35 are respectively fixed on the rotating seat 321, and the locking member 35 is used to lock the winding discharged from the material tray 28, and is wound outside the transformer 34 in coordination with the winding;

[0049] A guide motor 41 is installed on the processing platform 1 , and the guide motor 41 is used to drive the guide plate 21 to guide along the X direction so as to realize the guiding operation of the feeding assembly 2 .

[0050] For further information, see Attachment Figure 3 As shown, a lifting motor 23 is provided on the top of the stand 22, and the output shaft of the lifting motor 23 is connected to a lifting screw 231, and a mounting plate 24 is installed through the lifting screw 231, and the switching plate 25 is fixed by the mounting plate 24. Under the action of the lifting motor 23, the mounting plate 24 can drive the switching plate 25 to move up and down, thereby completing the sinking operation of the above-mentioned material tray 28;

[0051] It is worth noting that a switching motor 251 is installed on the outer side of the end of the switching plate 25, and a switching rod 252 driven by the switching motor 251 is connected to the bearing inside the switching plate 25, and a connecting block 253 is connected to the external thread of the switching rod 252, and a discharging motor 255 is installed on the connecting block 253, and a sinking rod 254 is also installed at the bottom of the connecting block 253. Under the drive of the switching motor 251, the connecting block 253 can drive the discharging motor 255 and the sinking rod 254 to move along the Y direction, so that they can be placed at the corresponding positions of different material trays 28, thereby driving the winding or insulating tape in the material tray 28 to perform winding or insulation operations for the transformer 34;

[0052] Among them, a support plate 26 is installed at the bottom of the stand 22, and the support plate 26 is placed in front of the switching plate 25. A plurality of pressure rods 261 are passed through the support plate 26. The pressure rods 261 are located at the upper and lower parts of the support plate 26, and a sinking plate 263 and a feed port 264 are respectively installed. A spring 262 is sleeved on the outside of the pressure rod 261, and the two ends of the spring 262 are respectively in contact with the bottom of the sinking plate 263 and the top of the support plate 26. A plurality of material trays 28 are installed on the sinking plate 263. A winding wire and an insulating tape are wound in the material tray 28 through a winding roller. The winding wire and the insulating tape pass through the support plate 26 and the feed port 264 and extend to the outside of one side of the feed port 264. The winding roller of the material tray 28 passes through and extends to On the outside of one side of the material tray 28, a feeding gear 281 is sleeved on the end of the winding roller, and the output shaft of the discharging motor 255 is sleeved on a driving gear 2551 meshing with the feeding gear 281. When the switching plate 25 is driven to sink by the lifting motor 23, the end of the sinking rod 254 will press against the sinking plate 263 and compress the spring 262 downward while moving downward. At the same time, the driving gear 2551 sleeved on the output shaft of the discharging motor 255 on the connecting block 253 will mesh with the feeding gear 281, so that the discharging motor 255 can drive the winding roller in the corresponding material tray 28 on the sinking plate 263 that is pushed down to rotate, and push the winding wire or insulating tape wound on the winding roller to the feeding port 264 to realize the feeding operation;

[0053] Furthermore, an electrode wire 27 is installed on the support plate 26. The electrode wire 27 is placed just in front of the feed port 264 and is used to disconnect the winding wire and the insulating tape. When a single material tray 28 sinks and completes feeding, the lifting motor 23 drives the switching plate 25 to reset. Under the action of the spring 262, the feed tray 28 is reset. At this time, the electrode wire 27 will be energized to generate pulse electric spark discharge between the electrode wire 27 and the winding wire or the insulating tape, generating high temperature to melt the metal or vaporize the insulating tape, thereby completing the material disconnection operation.

[0054] In the attached Figure 2 In the figure, a positioning motor 311 is installed at the end of the guide plate 31, and the output shaft of the positioning motor 311 is connected to a positioning rod 312. The positioning plate 32 is connected to the positioning rod 312 through a threaded connection. The positioning motor 311 drives the positioning rod 312 to rotate, and then the positioning plate 32 connected by its external threaded connection realizes reciprocating movement along the Y direction, so that the transformer component 34 can be positioned at the corresponding position of different material trays 28, and at the same time, the transformer component 34 can continuously move in the Y direction when winding, so that the winding can be evenly wound on the outside of the transformer component 34.

[0055] It is worth noting that the transformer 34 in this embodiment is composed of an iron core and a plurality of pins. The transformer 34 is provided with corresponding threading grooves at the pins. In order to allow the winding to pass through the threading grooves of the corresponding pins, refer to the attached Figure 4-5As shown, an electromagnetic component 33 is installed on the positioning plate 32, and the telescopic end of the electromagnetic component 33 is connected to an arc-shaped electromagnetic rod 331, and the electromagnetic rod 331 is connected to a side shaft of the rotating seat 321. Under the action of positive and negative power supply of the electromagnetic component 33, a positive or reverse Lorentz force is generated to push the electromagnetic rod 331 to slide back and forth. Since the electromagnetic rod 331 is arranged in an arc shape, it can push the rotating seat 321 to rotate along its shaft connection in the range of ∠30°-∠90° during its sliding process, thereby realizing the function of adjusting the offset angle of the transformer component 34 fixed on the rotating seat 321. When the transformer component 34 is offset by a certain angle, the winding sent out through the material tray 28 will penetrate into the threading groove and remain parallel to the pin. When the rotating seat 321 is reset, the winding will bend in front of the threading groove so that the winding operation can be performed with the rotation of the transformer component 34.

[0056] For further information, see Attachment Figure 5 As shown, the cross section of the rotating seat 321 is C-shaped, a clamping rod 323 is threadedly connected to the top of one side of the rotating seat 321, and a clamping block 3221 is connected to the inside of the other side of the rotating seat 321 and the end of the clamping rod 323 through a bearing, and a winding motor 322 is installed on one side of the end of the rotating seat 321. The winding motor 322 is used to drive the clamping block 3221 to rotate, and one of the clamping blocks 3221 is pushed to move horizontally by rotating the clamping rod 323 thread, so that the two clamping blocks 3221 can complete the function of clamping the transformer component 34, and the transformer component 34 clamped and fixed in the clamping block 3221 can be driven by the winding motor 322 to complete the rotation function, so as to realize the function of winding or wrapping the insulating tape;

[0057] At the same time, in the attached Figure 4 In the embodiment, a telescopic machine 351 is also installed on the top of one side of the rotating seat 321, and a push-pull plate 352 is connected to the telescopic end of the telescopic machine 351. The end of the push-pull plate 352 is connected to three groups of windings 354 through a rotating shaft. A winding motor 353 for driving the windings 354 to rotate is also installed on the push-pull plate 352. The windings 354 are elliptical in shape, and the rotating shaft of the push-pull plate 352 is connected to the surface of one end of the windings 354. The push-pull plate 352 is pushed toward the end of the transformer component 34 by the telescopic machine 351, so that the end of the windings 354 is inserted into the pin of the transformer component 34, and the winding wire sent out from the material tray 28 and passing through the transformer component 34 is sent to the inner side of the other end of the windings 354. The winding motor 353 is used to drive the windings 354 to rotate along the pins, so that the winding wire can be wound around the pins, thereby completing the fixation of the winding ends, and ensuring that the winding ends will not fall off during the winding operation of the transformer component 34.

[0058] Working principle: The transformer component 34 is fixed between the two clamping blocks 3221 by the clamping rod 323, and the external terminal is used to send instructions to the equipment PLC to control each electrical component. The transformer component 34 is reset by the positioning motor 311. After the electromagnetic component 33 drives the transformer component 34 to deviate and rotate to the angle corresponding to the required winding, the corresponding material tray 28 sinks to the front of the transformer component 34, and the winding wire is sent out to pass into the winding ring 354. After the winding wire and the corresponding pin of the transformer component 34 are wound by the winding motor 353, the electromagnetic component 33 drives the transformer component 34 to reset horizontally, so that the winding wire and the surface of the transformer component 34 are tightly attached and tightened, and then the winding motor 322 is driven to drive the transformer component 34 to rotate for winding. During the rotation, the positioning motor 311 continuously drives the transformer component 34 to move horizontally to ensure the uniformity of the transformer component 34 during winding. After the winding is completed, the material tray 28 is reset and raised. During the rising process, the electrode wire 27 is powered and high temperature is generated between the winding wire and the winding wire to disconnect the winding wire.

[0059] After a single winding is completed, the material tray 28 corresponding to the insulating tape is sunk and the end of the insulating tape is applied to the outside of the transformer component 34 winding through the feeding guide rail 4. The insulating tape is attached to the outside of the winding by utilizing its own adhesiveness. At the same time, the material is discharged through the discharging motor 255. The winding motor 322 drives the transformer component 34 to rotate, completing the winding operation of the insulating tape, and the insulating tape is disconnected by using the electrode wire 27. The above two steps are repeated to complete the transformer winding operation. In this process, the selection of winding specifications required for different windings can be controlled by PLC programming without manual access.

[0060] In this embodiment, all of the above-mentioned electrical components are controlled in real time through PLC programming of model S4-400. The PLC is integrated with a counter, an alarm, etc., which can realize automatic winding operation of the transformer component 34, and can solve the problems of inaccurate control of the number of turns of traditional manual winding, uneven winding tightness, poor insulation between windings, incorrect selection of winding wires, large repetitive workload resulting in differences in transformer performance, and low production efficiency due to uneven quality.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
