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 means that when winding the square iron core, workers need to cooperate with the winding mechanism and frequently release and fix the square iron core. 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

DETAILED DESCRIPTION

[0028] 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.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figure 1-Figure 10In an embodiment of the present invention, a transformer assembly device includes: a base 1, a rotating member 21, an elastic component and a deflection mechanism. On the one hand, when the square core is clamped, a gap is left between the first telescopic rod 22 or the second telescopic rod 23 and the side wall of the square core, so that the rotating member 3 can pass through, thereby avoiding the occurrence of interference. On the other hand, the first telescopic rod 22 can be alternately telescoped with the second telescopic rod 23 to complete the clamping of the square core, and the first telescopic rod 22 and the second telescopic rod 23 are in a state of simultaneously abutting against the square core, thereby avoiding the square core from losing support and falling due to the alternation moment when the two alternately abut the square core, thereby improving the stability of the entire winding operation, as follows: The base 1 is provided with a winding mechanism, which includes an arc-shaped bracket 2 provided on the base 1, a rotating member 3 is slidably installed in the arc-shaped bracket 2, and an annular protrusion 301 is provided on the side wall of the rotating member 3, and the annular protrusion 301 is slidably matched with an annular groove 201 provided on the arc-shaped bracket 2, wherein 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 core, the square core can enter the inside of the rotating member 3 and the arc-shaped bracket 2 from the notch of the rotating member 3, thereby facilitating the placement of the square core. Compared with the arrangement of the wire reel in the prior art, which needs to restore the wire reel to a ring state after the core is placed, the present application simplifies the operation process and improves production efficiency. The rotating member 3 is also provided with a traction ring 5 and a loading rod 4 for loading the coil; 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 arranged on the base 1, a first gear 7 and a second gear 9 are rotatably mounted on the vertical plate 6, the first gear 7 and the second gear 9 are connected by a belt 8, and the rotating shaft of the second gear 9 is connected to a driving motor 10 arranged on the vertical plate 6; The power assembly includes a rack plate 11 disposed on the rotating member 3 and coaxial with the rotating member 3 , and the rack plate 11 is adapted to the first gear 7 and the second gear 9 .

[0031] When in use, the coil disk with the coil wound on it is loaded onto the loading rod 4, and then the driving motor 10 is started, and the first gear 7 and the second gear 9 are rotated. At this time, the first gear 7, the second gear 9 cooperate with the rack plate 11, which can make the rotating part 3 move in a circular motion, and drive the coil disk and the traction ring 5 to move in a circular motion and pass through the square iron core to realize the winding of the coil.

[0032] Among them, by providing 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 increasing the winding speed.

[0033] Through the above arrangement, on the one hand, the placement and removal of the iron core are made more convenient, the preparation process before winding the coil is simplified, and the operation amount and difficulty are reduced. On the other hand, the first gear 7 and the second gear 9 are engaged with the rack plate 11 simultaneously or alternately, which can make the rotating part 3 rotate continuously, thereby realizing continuous operation and improving the winding speed.

[0034] See also Figure 7-Figure 9 The rotating member 21 is arranged on the base 1, and two sets of first telescopic rods 22 and second telescopic rods 23 are symmetrically slidably mounted 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; By providing two sets of first telescopic rods 22 and second telescopic rods 23, during the winding operation, the first telescopic rods 22 and the second telescopic rods 23 can alternately abut against the inner side of the square core, thereby achieving continuous clamping of the square core. On the one hand, the winding stability of the square core is ensured, and on the other hand, the winding operation can be carried out continuously without manual operation.

[0035] The elastic component is provided with multiple groups and connected with the first telescopic rod 22 and the second telescopic rod 23 respectively. The elastic component is provided with a convex shaft 17, and the convex shaft 17 cooperates with a fixing ring 18 provided on the base 1, so that the first telescopic rod 22 and the second telescopic rod 23 can move alternately toward the outside of the rotating member 21; 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; The rotating shaft 14 is provided with a plurality of guide grooves 1401 along its length direction, a slider 15 is slidably installed in the guide groove 1401, a pulling rod 20 is rotatably installed on the slider 15, and one end of the pulling rod 20 away from the slider 15 is rotatably connected to the first telescopic rod 22 and the second telescopic rod 23; The elastic component further includes a plurality of first springs 25 having one end fixedly connected to the rotating shaft 14 and the other end connected to the first telescopic rod 22 and the second telescopic rod 23; The slider 15 is provided with a connecting plate 16, and one end of the connecting plate 16 away from the slider 15 is rotatably connected to the convex shaft 17; The fixing ring 18 is connected to the driving assembly, and a protrusion 19 is formed on the inner wall of the fixing ring 18. The protrusion 19 cooperates with the convex shaft 17 to drive the first telescopic rod 22 and the second telescopic rod 23 to move alternately. The protrusion 19 protrudes from the inner wall of the fixing 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, the first telescopic rod 22 or the second telescopic rod 23 can be driven to move toward the outside of the rotating member 21; The central angle of the horizontal arc surface 1902 is greater than 90°.

[0036] In the initial state, only the first telescopic rod 22 abuts against the inner wall of the square core to clamp and fix the square core. At this time, during winding, the rotating member 3 can pass through the interior of the square core without interference. Specifically, when the first telescopic rod 22 abuts against the inner wall of the square core, the length direction of the first telescopic rod 22 is parallel to the axis of rotation of the rotating member 3 for circular motion. At this time, the first telescopic rod 22 abuts against the middle of the square core, leaving a gap between the first telescopic rod 22 and the side of the square core for the rotating member 3 to pass through. Based on this, interference between the rotating member 3 and the square core is avoided during winding.

[0037] When the coil is wound on the side of one side of the square core, the rotating shaft 14 will rotate. At this time, the square core can follow the rotating shaft 14 to make a circular motion. At the same time, the convex shaft 17 follows the rotating shaft 14 to make 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, and the second telescopic rod 23 is driven to move toward the outside of the rotating member 21 by the connecting plate 16, the slider 15 and the pulling rod 20 until the convex shaft 17 moves to the horizontal arc surface 1902, and the second telescopic rod 23 fits with the inner wall of the square core. At this time, since the central angle of the horizontal arc surface 1902 is greater than 90°, the first telescopic rod 22 also maintains contact with the first telescopic rod 22. The square core is in a state of abutment, 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, and then the convex shaft 17 moves downward under the drive of the first spring 25, so that the first telescopic rod 22 is retracted into the rotating member 21, and the first telescopic rod 22 and the second telescopic rod 23 are alternately supported. Based on the above principle, the first telescopic rod 22 can be alternately extended and retracted with the second telescopic rod 23 to complete the clamping of the square core, and the first telescopic rod 22 and the second telescopic rod 23 are in a state of abutting the square core at the same time, which avoids the square core losing support and falling due to the alternation when the two alternately abut the square core, thereby improving the stability of the entire winding operation.

[0038] Through the above arrangement, on the one hand, when the square core is clamped, a gap is left between the first telescopic rod 22 or the second telescopic rod 23 and the side wall of the square core, so that the rotating member 3 can pass through, thereby avoiding the occurrence of interference. On the other hand, the first telescopic rod 22 can be alternately telescoped with the second telescopic rod 23 to complete the clamping of the square core, and the first telescopic rod 22 and the second telescopic rod 23 are in a state of abutting against the square core at the same time, thereby avoiding the square core from losing support and falling off at the alternating moment when the two alternately abut against the square core, thereby improving the stability of the entire winding operation.

[0039] See also Figure 3-Figure 4 , Figure 7 , Figure 8 , Fig.10 The deflection mechanism is arranged on the base 1 and 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°; The driving assembly includes a slide groove 101 arranged on the base 1, and a sliding member 13 is slidably installed in the slide groove 101. The sliding member 13 is connected to a linear driving device 12 arranged on the base 1. The rotating shaft 14 passes through the sliding member 13 and is rotatably arranged. A ratchet 31 is arranged at one end of the rotating shaft 14 away from the rotating member 21, and the ratchet 31 is adapted to a ratchet plate 32 arranged on the base 1.

[0040] When in use, the linear drive device 12 can control the moving speed of the sliding member 13 according to the rotation speed of the rotating member 3, and then control the moving speed of the square iron core. During 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 spirally wound on one side of the square iron core during winding, thereby improving the tightness of the coil after winding and the product quality. At the same time, the cooperation between the ratchet 31 and the ratchet plate 32 can make the rotating shaft 14 rotate, so that after winding is completed on one side of the square iron core, it switches to the other side, thereby improving the degree of automation in the winding process.

[0041] The limiting structure includes a follower 26 coaxially fixedly connected to the rotating shaft 14, and a plurality of limiting grooves 2601 are equidistantly arranged on the follower 26; The limiting structure further comprises an elastic support structure arranged on the sliding member 13, on which a groove wheel 27 is rotatably mounted, and the groove wheel 27 is in rolling cooperation with the limiting groove 2601; The elastic support structure includes a hysteresis sleeve 30 fixedly mounted on the sliding member 13, a telescopic shaft 28 is slidably mounted in the hysteresis sleeve 30, one end of the telescopic shaft 28 is rotatably connected to the groove wheel 27, and a limit ring 2801 is provided on the telescopic shaft 28; One end of the 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 .

[0042] In the initial state, the second spring 29 is in a compressed state, at which time the groove wheel 27 and the limit groove 2601 are in abutment state, and when the rotating shaft 14 rotates, the groove wheel 27 can move along the length direction of the telescopic shaft 28 until the rotating shaft 14 rotates to a predetermined angle, and the second spring 29 drives the rotating shaft 14 to actively rotate by releasing elastic potential energy, and after the rotating shaft 14 is stable, the rotating shaft 14 rotates 90°, so that after one side of the square iron core is wound, the other side can actively switch to the winding station and maintain high stability. With the cooperation of the limit groove 2601 and the groove wheel 27, the rotating shaft 14 can be effectively prevented from excessive rotation due to inertia, thereby ensuring the rotation accuracy of the rotating shaft 14.

[0043] Through the above-mentioned arrangement, the winding of the rotating part 3 and the movement of the square iron core can cooperate with each other, so that the coil is spirally wound on one side of the square iron core during winding, thereby improving the tightness of the coil after winding and improving 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 switches to the other side, thereby improving the degree of automation in the winding process. In addition, the cooperation between the groove wheel 27 and the limiting groove 2601 can, on the one hand, enable the rotating shaft 14 to stably rotate 90°, so that after the winding is completed on one side of the square iron core, the other side can actively switch to the winding station. On the other hand, it can effectively prevent the rotating shaft 14 from excessive rotation due to inertia, thereby ensuring the rotation accuracy of the rotating shaft 14.

[0044] As an embodiment of the present invention, a method for automatically assembling and producing a transformer using the transformer assembly device is also proposed, comprising the following steps: Step 1: Place the iron core to be wound with the coil on the rotating member 21, and clamp the iron core using two sets of first telescopic rods 22 or two sets of second telescopic rods 23; Step 2: Start the winding mechanism to wind the coil on the iron core, and start the deflection mechanism to make the iron core move laterally under the action of the driving component, so that the coil is spirally wound on the iron core; Step 3: After the coil is wound to the end of one side of the iron core, the driving assembly 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 move alternately to continue clamping the iron core; Step 4: Repeat steps 2 to 3 above; Step 5: Remove the wound core package and set aside.
