[0002] A transformer is a device used to measure and convert current, voltage or power in power systems. It is widely used in power systems, electrical equipment, and automation control.

[0003] The transformer winding device is a device specially used for winding transformer core coils. It is mainly composed of a closed iron core and windings. During the winding process, in order to meet the winding efficiency of the copper wire, the controller controls the motor to rotate and drive the winding shaft to rotate for winding. The controller can also control the extension and retraction of the electric push rod, so that the winding device moves left and right on the slide rail, so that the copper wire is evenly wound on the winding shaft.

[0004] In the prior art, when performing automated copper wire winding on a square core, multiple independent manipulators need to work closely together. When the square core needs to be wound on the other side, multiple manipulators need to work together synchronously under a set program, so that the manipulators can release the clamping of the core toward the winding machine while adjusting the core position, so as to avoid interference with the copper wire winding of the core on that side. In addition, in order to ensure stable winding of the core, other manipulators need to cooperate to continue docking and clamping the core that has been wound. As a result, the existing copper wire winding device has a cumbersome operating procedure when winding on the other side of a square core, and due to the multi-point cooperation of independent electronic control equipment, there are problems of high equipment investment and maintenance costs.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] See also Figure 1-5 The present invention provides a technical solution: a copper wire winding device for a transformer core, comprising a processing table 1 and a winder 2 installed on the processing table 1, the processing table 1 is rotatably connected with a rotating frame 3 through a rotating shaft, the rotating frame 3 is slidably connected with four sliding frames 5 corresponding to the four sides of the core, the outer side of the sliding frame 5 is slidably connected with two slides 6, the slide 6 is fixed with a clamping plate 7, and a driving motor 4 for controlling the rotation of the rotating frame 3 is installed in the middle of the processing table 1.

[0032] The rotating frame 3 is a diamond-shaped structure, in which the spacing between two diagonal angles is larger than the spacing between the other two diagonal angles, so as to adapt to the distribution of the length and width of the square core. The output end of the driving motor 4 is fixed to the frame plate 17, and the frame plate 17 is controlled to rotate by the driving motor 4, so that the four sliding frames 5 rotate synchronously with the frame plate 17, and then the side of the core is clamped by the clamping plate 7 to realize the side winding of the core.

[0033] The clamping plate 7 is detachably fixed to the slide plate 6 by bolts, and the clamping plates 7 of different lengths can be disassembled and replaced to meet the requirements of changing the sides of square iron cores of different sizes. Rubber pads are fixed on the opposite ends of the two clamping plates 7, so that they have a certain deformation ability when clamping the iron core, avoiding damage to the outside of the iron core when clamping the iron core.

[0034] The processing table 1 is provided with a guiding structure for adjusting the positions of the sliding frame 5 and the rotating frame 3. The rotating frame 3 is provided with a connecting piece. When the sliding frame 5 slides relative to the rotating frame 3, the two slide plates 6 move along the sliding frame 5 under the action of the connecting piece to control the clamping state of the clamping plate 7 on the iron core.

[0035] When the winder 2 is winding one side of the iron core, there are always two clamping plates 7 responsible for clamping the side of the iron core. When one side of the iron core rotates with the rotation frame 3, before it is aligned with the winder 2, the sliding frame 5 will slide away from the corresponding side of the iron core under the action of the guide structure, so that the clamping plate 7 opens in advance and releases the contact with the iron core. When the side of the iron core is toward the winder 2 as the rotation frame 3 rotates, the corresponding sliding frame 5 will remain stationary relative to the rotating frame 3, so that the clamping plate 7 remains loosened from the iron core, which is beneficial for the winder 2 to perform continuous copper wire winding along the side of the square iron core. When the side of the iron core that has completed copper core winding rotates with the rotating frame 3, the sliding frame 5 corresponding to the side will slide along the rotating frame 3 toward the side of the iron core under the action of the guide structure. During this process, the two slides 6 will drive the clamping plates 7 to move toward each other under the action of the connecting parts, thereby clamping the side of the iron core, thereby ensuring that the iron core is in a stable mounting state when the other side of the iron core is being wound.

[0036] By controlling the rotation of the rotating frame 3, the sliding frame 5 can rotate with the rotating frame 3 and automatically adjust its position relative to the rotating frame 3, so that the clamping plate 7 can automatically adjust the tightness with the side of the iron core when rotating with the iron core. Under the premise of ensuring the stability of the iron core winding process, it avoids obstruction to the continuous winding of the iron core, thereby meeting the continuous winding process on the side of the square iron core, and further facilitating the improvement of the copper wire winding efficiency of the square coil. In addition, multiple clamping plates 7 are interconnected and coordinated under the action of the connecting parts and the guiding parts, reducing the adjustment and coordination of multiple electric equipment, thereby achieving the purpose of reducing the investment and maintenance cost of the equipment.

[0037] A support plate 28 is vertically slidably arranged on the processing table 1 to cooperate with the core frame, and a telescopic member for controlling the vertical movement of the support plate 28 is arranged on the processing table 1.

[0038] The support plate 28 is used to support the bottom of the iron core before and after the iron core winding process is completed, so that after the clamping state of the iron core by the four sliding frames 5 is released, the iron core can maintain a relatively stable support state, which is conducive to replacing and placing the iron core placed on the support plate 28 by a robot or manual means.

[0039] Embodiment 2:

[0040] The solution is basically the same as that in the first embodiment, except that Figure 2 and Figure 3As shown, the guiding structure includes a frame plate 17 which slides vertically between the processing table 1 and the rotating frame 3, a guide rod 8 which passes through the rotating frame 3 is fixedly provided at the bottom of the sliding frame 5, a sliding groove 301 which cooperates with the guide rod 8 to slide through is formed in the rotating frame 3, and a first guide groove 18 and a second guide groove 19 which cooperate with the guide rod 8 to slide are formed in the frame plate 17.

[0041] The first guide groove 18 and the second guide groove 19 are both composed of an outer ring groove, an inner ring groove, and a radial groove and an oblique groove connecting the inner ring groove and the outer ring groove;

[0042] When the guide rod 8 slides along the outer ring groove, the sliding frame 5 is stationary relative to the rotating frame 3, and the clamping plate 7 remains clamped on the iron core. When the guide rod 8 slides along the radial groove, the clamping plate 7 releases the iron core, and the sliding frame 5 slides away from the iron core. When the guide rod 8 slides along the inner ring groove, the clamping plate 7 remains loosened from the iron core. When the guide rod 8 slides along the oblique groove, the sliding frame 5 slides toward the iron core, and the clamping plate 7 clamps the iron core.

[0043] In this embodiment, when the side of the iron core slides toward the winder 2 as the rotating frame 3 rotates, the guide rod 8 will slide to the intersection of the outer ring groove and the radial groove. At this time, the sliding frame 5 will slide away from the corresponding side of the iron core under the action of the magnetic attraction force. During this process, the guide rod 8 will slide along the radial groove to the inner ring groove, and the slide plate 6 will also drive the two clamping plates 7 to slide open under the action of the linkage, thereby releasing the contact with the side of the iron core.

[0044] The two ends of the oblique groove are respectively connected to the outer ring groove and the inner ring groove. When the guide rod 8 slides along the oblique groove, the inner wall of the oblique groove presses the side wall of the guide rod 8, driving the sliding frame 5 fixed to the guide rod 8 to slide toward the corresponding side of the iron core. In this process, the two slides 6 will drive the clamping plates 7 to move toward each other under the action of the linkage until the side of the iron core is clamped.

[0045] A telescopic rod 21 for controlling the vertical movement of the frame plate 17 is installed in the processing table 1 . Two inclined blocks 20 are fixed on the top of the frame plate 17 . The two inclined blocks 20 are respectively located at the inner sides of the first guide groove 18 and the second guide groove 19 .

[0046] The telescopic rod 21 is an existing hydraulic or pneumatic telescopic method. The telescopic rod 21 controls the frame plate 17 to move in the vertical direction. When the square iron core completes the copper wire winding, the telescopic rod 21 controls the frame plate 17 to move downward, so that the first guide groove 18 and the second guide groove 19 release the restriction on the guide rod 8. At this time, the sliding frame 5 will slide toward the frame plate 14 under the action of magnetic attraction, so that the four sides of the iron core are in a loose state, thereby realizing the unloading of the iron core.

[0047] When the frame plate 17 is controlled to move upward by the telescopic rod 21, the inclined block 20 fixed on the frame plate 17 will drive the sliding frame 5 fixed to the guide rod 8 to slide toward the side of the iron core by acting on the bottom of the guide rod 8 until the guide rod 8 slides into the guide groove again. The clamping plate 7 will clamp the side of the iron core, thereby completing the installation of the iron core.

[0048] Embodiment three:

[0049] The solution is basically the same as that in the first embodiment, except that Figure 1-Figure 3 As shown, the linkage includes two wheels 9 rotatably connected to the inner side of the sliding frame 5, and a component driving the wheels 9 to rotate. The outer sides of the two wheels 9 are engaged with a chain 10, and both sides of the chain 10 are fixed to the two slide plates 6 through fixing blocks 11 respectively.

[0050] When the wheel disc 9 rotates, the chain 10 meshing with it will pull two slide plates 6 fixed to the fixed block 11 to move synchronously along the sliding frame 5. The wheel disc 9 is a sprocket wheel meshed with the chain 10.

[0051] The components driving the wheel disc 9 to rotate include a frame plate 14 fixed on the rotating frame 3, a magnetic sheet 1401 is fixed on the outer end of the frame plate 14, a transverse shaft 15 is fixed on the outer end of the frame plate 14, a sliding sleeve 12 coaxially fixed on one of the wheel discs 9 to slide through the transverse shaft 15, a protrusion 13 is formed on the inner wall of the sliding sleeve 12, and a slide rail 16 is formed on the side wall of the transverse shaft 15 to slide with the protrusion 13. The slide rail 16 is a spiral structure.

[0052] The sleeve 12 is made of iron-containing material. When the guide rod 8 is not restricted by the guide groove, the sleeve 12 will drive the sliding frame 5 to slide toward the frame plate 14 under the magnetic attraction of the magnetic sheet 1401. During this process, the protrusion 13 fixed on the inner wall of the sleeve 12 will slide along the slide rail 16. The inner wall of the slide rail 16 presses the outer wall of the protrusion 13, driving the sleeve 12 to drive the wheel 9 to rotate.

[0053] Embodiment 4:

[0054] The solution is basically the same as that in the first embodiment, except that Figure 2 and Figure 5 As shown, the telescopic member includes a bracket 24 fixed on the processing table 1 corresponding to the support plate 28, a transmission arm 27 rotatably connected to the outside of the bracket 24, and a component that drives the transmission arm 27 to rotate. A sleeve 26 is fixed to the bottom of the support plate 28, and the free end of the transmission arm 27 is rotatably connected to the sleeve 26.

[0055] The transmission arm 27 is composed of two arms of equal length that are rotatably connected. When the transmission arm 27 is rotated and unfolded, the sleeve 26 will drive the support plate 28 to move upward under the action of the transmission arm 27 to lift the iron core with copper wire wound around it. When the transmission arm 27 is rotated and folded, the support plate 28 moves downward to send the replaced iron core back into the clamping area of ​​the clamp 7.

[0056] The assembly driving the transmission arm 27 to rotate includes a gear 25 rotatably connected to the inner side of the bracket 24 and coaxially fixed with the transmission arm 27. A bending arm 22 corresponding to the gear 25 is fixed on the side wall of the frame plate 17. A meshing tooth 23 engaging with the gear 25 is formed on the side wall of the bending arm 22. A bending frame 29 is fixed on the processing table 1. A vertical rod 30 is fixed on the top of the bending frame 29. The sleeve 26 is slidably sleeved on the outer side of the vertical rod 30.

[0057] When the frame 17 moves in the vertical direction, the bending arm 22 fixed on the side wall of the frame 17 will act on the gear 25 through the meshing teeth 23, driving the transmission arm 27 coaxially fixed with the gear 25 to rotate, thereby driving the vertical movement of the support plate 28. During this process, the sleeve 26 fixed at the bottom of the support plate 28 will slide along the vertical rod 30.

[0058] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
