Description

Technical Field

[0001] The invention relates to a transformer production technology, in particular to transformer assembly equipment and an automatic assembly production method for a transformer. Background Art

[0002] The transformer is one of the important components of the electric energy meter. It is a device that converts voltage or current proportionally. The main function of the transformer is to convert high voltage or large current into low voltage or small current proportionally, so as to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment.

[0003] When assembling a transformer, it mainly involves the winding of the coil and the assembly of the upper shell and the lower shell. The winding quality of the coil is related to the product quality of the transformer.

[0004] Most of the existing transformer coil winding devices are composed of two parts, including an iron core rotating mechanism and a winding mechanism. The iron core rotating mechanism cooperates with the winding mechanism to evenly wind the coil on the annular iron core in a spiral shape. However, this device is not suitable for square iron cores. This results in workers needing to cooperate with the winding mechanism and frequently release and fix the square iron core when winding the square iron core. On the one hand, this can easily lead to a decrease in the winding quality of the coil. On the other hand, misoperation may cause injuries to workers, both of which are not conducive to the rapid winding production of square iron cores. Summary of the invention

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0052] Please refer to Figures 1-10, in the embodiment of the present invention, a mutual inductor assembly device includes: a base 1, a rotating member 21, an elastic assembly, and a deflection mechanism. On the one hand, when the square iron core is clamped, there is a gap between the first telescopic rod 22 or the second telescopic rod 23 and the side wall of the square iron core, so that the rotating member 3 can pass through, avoiding the occurrence of interference. On the other hand, the first telescopic rod 22 and the second telescopic rod 23 can alternately extend and retract to complete the clamping of the square iron core, and the first telescopic rod 22 and the second telescopic rod 23 are in a state of simultaneously abutting against the square iron core, avoiding the square iron core from falling due to the loss of support at the moment of alternation when the two alternately abut against the square iron core, improving the stability of the entire winding operation. Specifically as follows:

[0053] A winding mechanism is provided on the base 1. The winding mechanism includes an arc-shaped bracket 2 provided on the base 1. A rotating member 3 is slidably installed inside the arc-shaped bracket 2. An annular protrusion 301 is provided on the side wall of the rotating member 3. The annular protrusion 301 is slidably matched with an annular groove 201 provided on the arc-shaped bracket 2. The central angles of the arc-shaped bracket 2 and the rotating member 3 are both greater than 180°. Since the rotating member 3 is an incomplete annular structure, when placing the square iron core, the square iron core can enter the inside of the rotating member 3 and the arc-shaped bracket 2 from the notch of the rotating member 3, facilitating the placement of the square iron core. Compared with the existing technology that uses a wire reel, after the iron core is placed, the wire reel needs to be restored to an annular state. This application simplifies the operation process and improves production efficiency;

[0054] A traction ring 5 and a loading rod 4 for loading coils are further provided inside the rotating member 3;

[0055] The winding mechanism further includes a power assembly for driving the rotating member 3 to rotate relative to the arc-shaped bracket 2. The power assembly includes a vertical plate 6 provided on the base 1. A first gear 7 and a second gear 9 are rotatably installed on the vertical plate 6. The first gear 7 and the second gear 9 are connected by a belt 8. The rotating shaft of the second gear 9 is connected to a driving motor 10 provided on the vertical plate 6;

[0056] The power assembly further includes a rack plate 11 provided on the rotating member 3 and coaxial with the rotating member 3. The rack plate 11 is adapted to the first gear 7 and the second gear 9.

[0057] During use, load the coil reel wound with coils onto the loading rod 4, then start the driving motor 10, and rotate the first gear 7 and the second gear 9. At this time, the first gear 7, the second gear 9 and the rack plate 11 cooperate to enable the rotating member 3 to perform a circular motion, and drive the coil reel and the traction ring 5 to perform a circular motion through the square iron core to realize the winding of the coil.

[0058] Among them, by setting the first gear 7 and the second gear 9, the first gear 7 and the second gear 9 can be meshed with the rack plate 11 simultaneously or alternately, so as to maintain the continuous rotation of the rotating member 3, thereby realizing continuous winding operation and improving the winding speed.

[0059] Through the above settings, on the one hand, it makes the placement and taking of the iron core more convenient, simplifies the preparation process before winding the coil, reduces the operation amount and operation difficulty. On the other hand, the first gear 7 and the second gear 9 are meshed with the rack plate 11 simultaneously or alternately, which can make the rotating member 3 rotate continuously, thereby realizing continuous operation and improving the winding speed.

[0060] Please refer to Figures 7-9 , the rotating member 21 is arranged on the base 1, and two groups of first telescopic rods 22 and second telescopic rods 23 are symmetrically and slidably installed on the rotating member 21, and rubber pads 24 are arranged at the ends of the first telescopic rods 22 and the second telescopic rods 23;

[0061] By setting two groups of first telescopic rods 22 and second telescopic rods 23, during the winding operation, the first telescopic rod 22 and the second telescopic rod 23 can alternately abut against the inner side of the square iron core, thereby realizing the continuous clamping of the square iron core. On the one hand, it ensures the winding stability of the square iron core, and on the other hand, it can make the winding operation continuous without manual operation.

[0062] A plurality of groups of elastic components are provided and are respectively connected to the first telescopic rod 22 and the second telescopic rod 23. A convex shaft 17 is arranged on the elastic component, and the convex shaft 17 cooperates with a fixed ring 18 arranged on the base 1, which can make the first telescopic rod 22 and the second telescopic rod 23 stagger and move towards the outside of the rotating member 21;

[0063] The elastic component includes a rotating shaft 14 rotatably connected to the driving component, and one end of the rotating shaft 14 away from the driving component is connected to the rotating member 21;

[0064] A plurality of groups of guiding grooves 1401 are arranged along the length direction of the rotating shaft 14, a slider 15 is slidably installed in the guiding grooves 1401, a pull rod 20 is rotatably installed on the slider 15, and one end of the pull rod 20 away from the slider 15 is rotatably connected to the first telescopic rod 22 and the second telescopic rod 23;

[0065] The elastic component further includes a plurality of first springs 25, one end of each first spring is fixedly connected to the rotating shaft 14, and the other end is connected to the first telescopic rod 22 and the second telescopic rod 23;

[0066] A connecting plate 16 is installed on the slider 15, and one end of the connecting plate 16 away from the slider 15 is rotatably connected to the convex shaft 17;

[0067] The fixed ring 18 is connected to the driving assembly, and a protruding portion 19 is formed on the inner wall of the fixed ring 18. The protruding portion 19 cooperates with the convex shaft 17 and can drive the first telescopic rod 22 and the second telescopic rod 23 to act alternately;

[0068] The protruding portion 19 protrudes from the inner wall of the fixed ring 18 and is formed with a spiral inclined surface 1901, a horizontal arc surface 1902 and a vertical surface 1903. When the convex shaft 17 cooperates with the spiral inclined surface 1901, it can drive the first telescopic rod 22 or the second telescopic rod 23 to move towards the outside of the rotating member 21;

[0069] The central angle of the horizontal arc surface 1902 is greater than 90°.

[0070] In the initial state, only the first telescopic rod 22 abuts against the inner wall of the square iron core to clamp and fix the square iron core. At this time, when winding, the rotating member 3 can pass through the inside of the square iron core without interference. Specifically, when the first telescopic rod 22 abuts against the inner wall of the square iron core, the length direction of the first telescopic rod 22 is parallel to the rotating shaft of the rotating member 3 making a circular motion. At this time, the first telescopic rod 22 abuts against the middle of the square iron core, leaving a gap between the first telescopic rod 22 and the side of the square iron core, so that the rotating member 3 can pass through. Based on this, it is avoided that the rotating member 3 interferes with the square iron core during winding.

[0071] When the winding of the coil is completed on one side of the square iron core, the rotating shaft 14 will rotate. At this time, the square iron core can follow the rotating shaft 14 to perform a circular motion. At the same time, the convex shaft 17 follows the rotating shaft 14 to perform a circular motion. At this time, the convex shaft 17 corresponding to the second telescopic rod 23 will abut against the spiral inclined surface 1901, and under the guidance of the spiral inclined surface 1901, the convex shaft 17 moves upward. By using the connecting plate 16, the slider 15 and the pull rod 20, the second telescopic rod 23 is driven to move towards the outside of the rotating member 21 until when the convex shaft 17 moves onto the horizontal arc surface 1902, the second telescopic rod 23 fits against the inner wall of the square iron core. At this time, since the central angle of the horizontal arc surface 1902 is greater than 90°, the first telescopic rod 22 also remains in a state of abutting against the square iron core. And as the rotating shaft 14 continues to rotate, the convex shaft 17 corresponding to the first telescopic rod 22 will move to the end of the horizontal arc surface 1902. Subsequently, the convex shaft 17 moves downward under the drive of the first spring 25, so that the first telescopic rod 22 retracts into the rotating member 21, realizing the alternating support of the first telescopic rod 22 and the second telescopic rod 23. Based on the above principle, the first telescopic rod 22 can alternately extend and retract with the second telescopic rod 23 to complete the clamping of the square iron core, and the first telescopic rod 22 and the second telescopic rod 23 are in a state of simultaneously abutting against the square iron core, avoiding the square iron core from falling due to the loss of support at the moment of alternation when the two alternately abut against the square iron core, and improving the stability of the entire winding operation.

[0072] Through the above settings, on the one hand, when the square iron core is clamped, there is a gap between the first telescopic rod 22 or the second telescopic rod 23 and the side wall of the square iron core, which can allow the rotating member 3 to pass through, avoiding the occurrence of interference phenomena. On the other hand, the first telescopic rod 22 can alternately extend and retract with the second telescopic rod 23 to complete the clamping of the square iron core, and the first telescopic rod 22 and the second telescopic rod 23 are in a state of simultaneously abutting against the square iron core, avoiding the square iron core from falling due to the loss of support at the moment of alternation when the two alternately abut against the square iron core, and improving the stability of the entire winding operation.

[0073] Please refer to Figures 3-4 、 Figure 7 、 Figure 8 、 Figure 10 The deflection mechanism is arranged on the base 1 and is connected to the elastic component. The deflection mechanism includes a driving component and a limiting structure. The driving component cooperates with the limiting structure to enable the rotating member 21 to rotate 90°;

[0074] The driving assembly includes a sliding groove 101 provided on the base 1. A sliding member 13 is slidably installed in the sliding groove 101. The sliding member 13 is connected to a linear driving device 12 provided on the base 1. The rotating shaft 14 passes through the sliding member 13 and is rotatably arranged. A ratchet 31 is provided at one end of the rotating shaft 14 away from the rotating member 21. The ratchet 31 is adapted to a ratchet plate 32 provided on the base 1.

[0075] During use, the linear driving device 12 can control the moving speed of the sliding member 13 according to the rotating speed of the rotating member 3, and further control the moving speed of the square iron core. In this process, the winding of the rotating member 3 and the movement of the square iron core cooperate with each other, so that the coil can be wound spirally on one side of the square iron core during winding, thereby improving the tightness of the wound coil and the product quality. At the same time, the cooperation between the ratchet 31 and the ratchet plate 32 can cause the rotating shaft 14 to rotate, so that after the winding is completed on one side of the square iron core, it can be switched to the other side, thereby improving the automation degree during the winding process.

[0076] The limiting structure includes a follower 26 fixedly connected coaxially with the rotating shaft 14. A plurality of limiting grooves 2601 are arranged on the follower 26 at equal circumferential intervals;

[0077] The limiting structure further includes an elastic support structure provided on the sliding member 13. A grooved pulley 27 is rotatably installed on the elastic support structure. The grooved pulley 27 is in rolling cooperation with the limiting grooves 2601;

[0078] The elastic support structure includes a hysteresis sleeve 30 fixedly installed on the sliding member 13. A telescopic shaft 28 is slidably installed in the hysteresis sleeve 30. One end of the telescopic shaft 28 is rotatably connected to the grooved pulley 27, and a limiting ring 2801 is provided on the telescopic shaft 28;

[0079] One end of a second spring 29 sleeved on the telescopic shaft 28 is connected to the limiting ring 2801, and the other end is connected to the inner wall of the hysteresis sleeve 30.

[0080] In the initial state, the second spring 29 is in a compressed state. At this time, the grooved pulley 27 is in contact with the limiting grooves 2601. When the rotating shaft 14 rotates, the grooved pulley 27 can move along the length direction of the telescopic shaft 28 until after the rotating shaft 14 rotates to a predetermined angle, the second spring 29 releases elastic potential energy to drive the rotating shaft 14 to rotate actively. After the rotating shaft 14 stabilizes, the rotating shaft 14 rotates 90°, so that after the winding is completed on one side of the square iron core, the other side can be actively switched to the winding station and maintain high stability. And with the cooperation of the limiting grooves 2601 and the grooved pulley 27, it can effectively prevent the rotating shaft 14 from over-rotating due to inertia and ensure the rotation accuracy of the rotating shaft 14.

[0081] With the above settings, the winding of the rotating member 3 and the movement of the square iron core can cooperate with each other, so that the coil is wound in a spiral shape on one side of the square iron core during winding, improving the tightness of the wound coil and the product quality. At the same time, the cooperation between the ratchet wheel 31 and the ratchet plate 32 enables the rotating shaft 14 to rotate. Thus, after the winding is completed on one side of the square iron core, it can be switched to the other side, improving the automation degree during the winding process. Moreover, the cooperation between the grooved pulley 27 and the limiting groove 2601 can, on the one hand, enable the rotating shaft 14 to rotate stably by 90°, so that after the winding is completed on one side of the square iron core, the other side can be actively switched to the winding station, and on the other hand, effectively prevent the rotating shaft 14 from over-rotating due to inertia, ensuring the rotation accuracy of the rotating shaft 14.

[0082] As an embodiment of the present invention, a method for automatically assembling and producing an instrument transformer using the above-mentioned instrument transformer assembling device is also proposed, including the following steps:

[0083] Step 1: Place the iron core of the coil to be wound on the rotating member 21, and clamp the iron core using two groups of first telescopic rods 22 or two groups of second telescopic rods 23.

[0084] Step 2: Start the winding mechanism, wind the coil on the iron core, and at the same time start the deflection mechanism to make the iron core move horizontally under the action of the driving component, so that the coil is wound around the iron core in a spiral shape.

[0085] Step 3: After the coil is wound to the end of one side of the iron core, the driving component cooperates with the limiting structure to drive the iron core to rotate 90°. At this time, the first telescopic rod 22 and the second telescopic rod 23 can act alternately to continuously clamp the iron core.

[0086] Step 4: Repeat the above steps 2 to 3.

[0087] Step 5: Remove the wound iron core and package it for later use.
