Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment manufacturing, and in particular to a vertical winding device for transformers and a coil. BACKGROUND

[0002] In order to facilitate subsequent transfer and improve winding efficiency, the existing technology generally forms multiple segments and multiple layers of ring-shaped coils in a neat stack on the outer wall of the horizontal winding device core at one time. At the same time, the ring-shaped coils are pre-fabricated on the buffer cylinder according to the required size and height, and can be transferred to the outer wall of the transformer sleeve as a whole or in segments when needed, greatly reducing the manual operation time, ensuring the stability and smoothness of the coil transfer process, and improving the assembly quality.

[0003] In the prior art, the binding ropes are generally arranged equidistantly on the outer wall of the horizontally arranged buffer core. When the electromagnetic wire is wound to a certain height on the outer wall of the buffer core to form a ring-shaped coil, the worker needs to manually pull out the corresponding length of the binding rope and reserve a margin, and then restart the winding device for continuous winding. This repeated operation finally forms multiple segments and multiple layers of ring-shaped coils on the outer wall of the buffer core. However, this method highly depends on manual cooperation and real-time supervision, which not only has high labor intensity, but also makes it difficult for workers to simultaneously manage multiple winding devices, seriously restricting the production efficiency and consistency.

Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application.

[0042] Referring to Figures 1-12 A transformer vertical winding device and coil, comprising a controller 1, a mounting shell 3 and a buffer die core 241, the buffer die core 241 is rolled from a steel plate, the outer surface is smoothly finished, and the outer surface is wrapped with a layer of soft insulating corrugated paper with air holes, a base 23 is welded at the bottom of the mounting shell 3, and a storage type winding mechanism is arranged at the top of the mounting shell 3, which is used for pre-winding and storing straight copper wires, so that the copper wires can be kept in close contact when released to the buffer die core 241, the storage type winding mechanism comprises a storage ring 13, a supporting disc 9, a fixed cylinder 16 and a wire harness guiding and releasing mechanism, the wire harness guiding and releasing mechanism guides the electromagnetic wire to the outer wall of the storage ring 13 and releases it, the fixed cylinder 16 is integrally formed at the top of the supporting disc 9 and is welded on the top partition plate 2, the top partition plate 2 is welded on the top of the mounting shell 3, and the storage ring 13 is welded at the bottom of the supporting disc 9.

[0043] The storage ring 13 serves as a temporary storage container for the electromagnetic wire to be wound, and the electromagnetic wire is pre-wound in the storage ring 13 before being wound on the outer wall of the buffer die core 241, so that the electromagnetic wire is forced to be pre-bent, and the diameter of the storage ring 13 is slightly larger than the diameter of the buffer die core 241, when the electromagnetic coil is released to the outer wall of the buffer die core 241 through the wire harness guiding and releasing mechanism, the electromagnetic wire is loosely wound on the outer wall of the buffer die core 241, which can reduce the rebound and tension concentration of the electromagnetic wire, ensure uniform stacking of the annular coil, and facilitate subsequent workers to use tools to transfer the pre-wound winding to the real transformer column.

[0044] The wire harness guiding and releasing mechanism comprises a driving gear 401, a driven gear 5, a main drive motor 4 and a center cylinder 6, the center cylinder 6 is rotatably arranged on the top partition plate 2 by a bearing, since the wire harness guiding and releasing mechanism is used to guide the winding of the entire electromagnetic wire, and the center cylinder 6 of the entire wire harness guiding and releasing mechanism needs to rotate.

[0045] Therefore the outer wall of the central cylinder 6 is welded with the driven gear 5, the driven gear 5 is stably engaged with the driving gear 401, the driving gear 401 is fixedly connected with the output end of the main drive motor 4, the main drive motor 4 is fixedly arranged on the top of the top partition plate 2, and the main drive motor 4 can drive the central cylinder 6 to rotate through the driving gear 401 and the driven gear 5 on the side of the central cylinder 6, so that the electromagnetic wire to be wound can be inserted from the top end of the central cylinder 6, in order to reduce the output speed of the main drive motor 4 and expand the output torque, when the driving gear 401 and the driven gear 5 are selected, the number of teeth of the driving gear 401 is less than the number of teeth of the driven gear 5.

[0046] Finally with reference to Figure 1 In order to facilitate the guidance of the to-be-wound electromagnetic wire, the top of the mounting shell 3 is sequentially provided with guide wheels, and the mounting shell 3 is provided with a hole at the top of the central cylinder 6, so as to facilitate threading.

[0047] The bottom of the central cylinder 6 is fixedly provided with a driving cross rod 10, one end of the driving cross rod 10 is rotatably connected with a wire guide wheel 12 through a pin shaft, the other end of the driving cross rod 10 is fixedly provided with a transmission ring 171 through a bolt, the other end of the transmission ring 171 is fixedly arranged on a mounting folding rod 17 through a bolt, the bottom of the mounting folding rod 17 is rotatably connected with an expansion pulley 15 through a pin shaft, and the outer wall of the storage ring 13 and the expansion pulley 15 is commonly sleeved with a release flat belt 14, when the integrated structure at the bottom of the central cylinder 6 is forced to rotate, the contact position between the release flat belt 14 and the storage ring 13 will change, the height of the release flat belt 14 is less than the height of the storage ring 13, and the part of the storage ring 13 above the release flat belt 14 is used for storing the to-be-released coil.

[0048] The mounting folding rod 17 is fixedly arranged with a guide small ring 18 on the inner side of the expansion pulley 15, in actual installation, the bottom of the driving cross rod 10 is provided with a vertical groove 11, the worker pulls the electromagnetic wire to pass through the vertical groove 11 and the bottom of the wire guide wheel 12, and finally the electromagnetic wire is inserted from the outside of the guide small ring 18 and is pre-wound on the outer wall of the storage ring 13 above the release flat belt 14.

[0049] The base 23 is symmetrically provided with a guide rail 22, the guide rail 22 is slidably connected with a storage plate 24 along the horizontal direction, a buffer mold core 241 is placed on the top of the storage plate 24, the storage plate 24 drives the buffer mold core 241 to move back and forth below the storage type winding mechanism, after the coil is wound, the worker can pull away the storage plate 24 from the bottom of the storage ring 13, so as to provide convenience for subsequent assembly or transportation.

[0050] The mounting shell 3 is symmetrically provided with an extension rod 25 fixed by bolts, and the extension rod 25 is fixedly provided with a vertical column 251. The base 23 is sequentially provided with a fixed limiting assembly and a movable limiting assembly on both sides of the buffer mold core 241. The fixed limiting assembly and the movable limiting assembly cooperate to guide the storage type wire winding mechanism to release the magnet wire to the outer wall of the buffer mold core 241. The fixed limiting assembly comprises a guide inclined rod 19, a common horizontal rod 20 and a fixed folding column 21. One end of the guide inclined rod 19 is fixed by bolts at the bottom of the top partition plate 2. The other end of the guide inclined rod 19 is fixed by bolts and provided with the common horizontal rod 20. The common horizontal rod 20 is symmetrically fixed at both ends and provided with the fixed folding column 21.

[0051] The movable limiting assembly comprises an extension frame 28, a movable folding column 27 and a vertical plate 29. The outer wall of the vertical column 251 is rotationally connected with a fixed block 26. The side surface of the fixed block 26 is threadedly screwed with a locking crank 261. The side surface of the fixed block 26 is fixedly provided with the extension frame 28. The side surface of the extension frame 28 is fixedly provided with the movable folding column 27. The fixed folding column 21 and the movable folding column 27 each comprise a vertical section and an inclined section. The two fixed folding columns 21 and the movable folding column 27 form a ring-shaped constraint space and have a structure of being wide at the top and narrow at the bottom. The storage type wire winding mechanism is guided to release the magnet wire to the outer wall of the buffer mold core 241. When the locking crank 261 is screwed tightly, the fixed block 26 cannot rotate around the vertical column 251. When the locking crank 261 is loosened, the two movable folding columns 27 can rotate away from the side surface of the storage plate 24, thereby facilitating the storage of the buffer mold core 241 on the top of the storage plate 24.

[0052] The base 23 is provided with a to-position pull line mechanism on one side of the movable limiting assembly. The to-position pull line mechanism pulls the outer wall of the buffer mold core 241 to a packaging length. The to-position pull line mechanism comprises a drive cylinder 33, an indirect block 34, an installation frame 36, a movable clamping jaw 361 and a fixed clamping jaw 37. The drive cylinder 33 is fixed by bolts on the mounting block 32. The side surface of the mounting block 32 is fixed by bolts and provided with an extension block 31. The side surface of the extension frame 28 is integrally welded with the vertical plate 29. The side surface of the vertical plate 29 is provided with a vertical groove 291 and a vertical guide groove 292. The extension block 31 extends into the vertical guide groove 292. Therefore, the mounting block 32 provided with the drive cylinder 33 can stably move in the vertical direction.

[0053] Since the drive cylinder 33 is provided with two, and the drive cylinder 33 needs to displace in the vertical direction, in order to ensure that the drive cylinder 33 moves in the vertical direction synchronously, the base 23 must be fixedly provided with a common drive assembly on the side surface. The common drive assembly drives the two drive cylinders 33 to act synchronously. The common drive assembly comprises a vertical electric push rod 8 and a horizontal horizontal rod 7. The vertical electric push rod 8 is fixed by bolts vertically on the base 23.

[0054] Since two active folding columns 27 must rotate around the vertical column 251 when the storage plate 24 accesses the buffer mold core 241, the driving air cylinder 33 on the vertical plate 29 will also move synchronously, so the output end of the vertical electric push rod 8 is fixedly provided with a horizontal cross rod 7, and a driving groove 71 is formed at the end of the horizontal cross rod 7. The driving groove 71 extends into the outer wall of the driving air cylinder 33. At this time, even if the driving air cylinder 33 moves, the vertical electric push rod 8 can also lift the driving air cylinder 33 to move in the vertical direction through the driving groove 71 on the horizontal cross rod 7. In addition, the step distance of the vertical electric push rod 8 is set as the height of a single annular winding.

[0055] The output end of the driving air cylinder 33 is fixedly provided with an indirect block 34, an extension column 301 is movably inserted into the side surface of the indirect block 34, a connecting spring 44 is movably inserted into one end of the extension column 301, a receiving groove 341 is formed in the top of the indirect block 34, and a top bolt 35 is movably inserted into the top of the receiving groove 341. The top bolt 35 is screwed into the top of the extension column 301, so that the indirect block 34 and the mounting frame 36 have flexibility.

[0056] The other end of the extension column 301 is integrally welded and fixedly provided with the mounting frame 36, the bottom of the mounting frame 36 is welded and fixedly provided with a fixed clamp jaw 37, the side surface of the mounting frame 36 is provided with an avoiding groove 362, the mounting frame 36 is movably inserted into the vertical direction. The active clamp jaw 361 is provided with a self-locking and self-releasing mechanism, which is in contact with the outer wall of the buffer mold core 241. When the self-locking and self-releasing mechanism is in contact with the outer wall of the buffer mold core 241, it will automatically clamp the binding line due to the mechanical structure. When the self-locking and self-releasing mechanism is reset, it will automatically release the binding line. It does not rely on the cooperation of multiple sensors. Finally, in order to protect the self-locking and self-releasing mechanism, the top of the mounting frame 36 is fixedly provided with an external cover 30 by means of a bolt.

[0057] The self-locking and self-releasing mechanism includes a vertical tooth rod 40, an internal gear 41, a locking ratchet 42, an external gear 46, a release cross rod 39, and a horizontal tooth rod 38. The vertical tooth rod 40 is fixedly welded on the side surface of the active clamp jaw 361 after passing through the avoiding groove 362. The vertical tooth rod 40 is stably engaged with the internal gear 41 on the side surface. The internal gear 41 is rotatably arranged on the side surface of the mounting frame 36 by means of a pin shaft. The internal gear 41 is fixedly provided with the external gear 46 on the side surface in a concentric manner. The external gear 46 is fixedly provided with the locking ratchet 42 on the outer wall. The internal gear 41, the external gear 46, and the locking ratchet 42 are concentrically arranged.

[0058] The installation frame 36 is rotatably connected with the locking arc lever 43 at the bottom of the locking ratchet 42 by a pin shaft, the head of the locking arc lever 43 is embedded into the tooth groove of the locking ratchet 42, the installation frame 36 is provided with the elastic washer 45 at the bottom of the locking arc lever 43 by bolt fixing, the external gear 46 is stably engaged with the horizontal toothed rod 38, the other end of the horizontal toothed rod 38 is fixedly welded on the side surface of the indirect block 34, one end of the release cross rod 39 is fixedly welded on the side surface of the installation block 32, the other end of the release cross rod 39 extends into the top of the locking arc lever 43.

[0059] The controller 1 is fixedly arranged on the side surface of the installation casing 3 by bolt, all electrical components of the whole device are connected to the controller 1, and the PLC controller is adopted in the selection of the controller 1.

[0060] The specific implementation steps and principles of the application are as follows:

[0061] When the storage type winding mechanism is prepared, the two extension frames 28 are rotated around the two vertical columns 251, the buffer mold core 241 at the top of the storage plate 24 is inserted into the lower part of the storage type winding mechanism, then the two extension frames 28 are rotated to the initial position, finally the locking crank 261 is tightened, the two fixed folding columns 21 and the movable folding column 27 form a ring-shaped constraint space, the electromagnetic wire is inserted from the top of the center cylinder 6, workers pull the electromagnetic wire to pass through the vertical groove 11 and the bottom of the wire guide wheel 12, finally the electromagnetic wire is inserted from the outside of the guide ring 18 and is pre-wound on the outer wall of the storage ring 13 above the release flat band 14, at the same time, the wire cylinder for winding and binding the wire is placed on the top of the buffer mold core 241, and two vertical binding wires are placed on the side surface of the installation frame 36 outside the buffer mold core 241.

[0062] When the main drive motor 4 is started, the driving cross rod 10, the installation folding rod 17 and the enlarged belt wheel 15 integrated structure are rotated by the driving of the driving gear 401 and the driven gear 5, on the one hand, the guide ring 18 is wound with a certain length of electromagnetic wire on the top of the storage ring 13, on the other hand, when the enlarged belt wheel 15 moves, the contact position of the release flat band 14 and the storage ring 13 is changed, so that the annular electromagnetic wire is released, and the annular electromagnetic wire falls into the top of the buffer mold core 241.

[0063] When the controller 1 reaches the set time, the main drive motor 4 is stopped, the storage type winding mechanism stops paying out the thread, the control drive cylinder 33 is extended, and when the movable jaw 361 contacts the side wall of the buffer mold core 241, the engaging spring 44 is compressed. At this time, the horizontal toothed rod 38 drives the movable jaw 361 to approach the fixed jaw 37 to hold the binding thread through the external gear 46, the internal gear 41, and the vertical toothed rod 40. During this period, due to the one-way locking of the locking ratchet 42 and the locking arc rod 43, the external gear 46, the internal gear 41, and the locking ratchet 42 cannot rotate. After the controller 1 sets the main drive motor 4 to run for a period of time, the control drive cylinder 33 is retracted, the movable jaw 361 and the fixed jaw 37 pull out a certain length of binding thread. When the release crossbar 39 starts to resist the locking arc rod 43, the locking arc rod 43 is forced to rotate and compress the elastic washer 45, the head of the locking arc rod 43 is turned away from the locking ratchet 42, and the external gear 46, the internal gear 41, and the locking ratchet 42 can rotate freely. At this time, due to the reset of the engaging spring 44, the horizontal toothed rod 38 drives the movable jaw 361 to move away from the fixed jaw 37 through the above structure to return to the initial position.

[0064] The above steps are repeated to form multiple segments of the annular coil to be bound on the outer wall of the buffer mold core 241. Workers use scissors to cut the multiple binding threads and segmentally bind the multiple annular coils.

[0065] In the initial state, the vertical electric push rod 8 is in the retracted state, driving the drive cylinder 33 at the end of the horizontal crossbar 7 to the bottom end of the vertical plate 29. The drive cylinder 33 is in the retracted state, and the movable jaw 361 and the fixed jaw 37 on the same mounting frame 36 are farthest apart.

[0066] The above description is only a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes within the technical scope disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
