Description

Technical Field

[0001] This invention relates to the field of network transformer manufacturing technology, and in particular to a method and equipment for automatically torturing network transformer taps. Background Technology

[0002] With the rapid development of modern information and communication technologies, network transformers, as key components in Ethernet devices for signal transmission, electrical isolation, and impedance matching, directly affect the stability and reliability of communication systems. As network speeds continue to increase and application scenarios diversify, the market's functional requirements for network transformers are becoming increasingly complex, which also places higher demands on their manufacturing processes.

[0003] One of the core components of a network transformer is the coil, and the winding process of the coil is a crucial factor determining the transformer's performance. In actual production, to meet different transformer functional requirements, a single coil often needs to incorporate two or more magnetic rings. Specific electrical properties are achieved through the synergistic effect between these magnetic rings. Among these, the T1 and T2 magnetic rings are a common combination, electrically connected via a tap structure to achieve signal coupling and transmission.

[0004] Specifically, such as Figure 8 As shown, a second tap 101 connects the T1 magnetic ring 110 and the T2 magnetic ring 120, the T2 magnetic ring extends separately with a first tap 101, and the T1 magnetic ring extends separately with a third tap 103. The arrangement and connection of these taps directly affect the transformer's turns ratio, isolation effect, and signal transmission quality.

[0005] Currently, based on the performance requirements of some customers for transformers, during the online production process, it is necessary to wind the originally separate second tap 102 with the first tap 101 together to further optimize the transformer's performance parameters.

[0006] However, existing transformer manufacturing equipment has limitations in automating the winding process. Existing equipment is primarily designed for conventional tap lead-out and fixing, and cannot perform the precise winding of the second tap 102 and the first tap 101. Manual winding is not only inefficient and unable to meet the demands of large-scale production, but also prone to errors that can compromise the tightness and consistency of the winding, thus affecting the performance stability and product yield of the network transformer.

[0007] Therefore, in view of the problem that the existing network transformer production equipment cannot achieve the winding of the second tap 102 and the first tap 101, it is urgent to improve the production equipment to realize the automation and precision of this winding action, thereby improving production efficiency and product quality and meeting the market demand for high-performance network transformers. Summary of the Invention

[0008] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a method and device for automatically toggling the taps of a network transformer.

[0009] A method for automatically toggling taps of a network transformer designed for this purpose includes the following steps:

[0010] S1. The third tap is clamped by the first clamping element, the T2 magnetic ring is clamped by the second clamping element, and the first tap is clamped by the third clamping element.

[0011] S2. The moving module drives the second clamping element to move the T2 magnetic ring away from the first clamping element and the third clamping element, so that the first tap and the second tap form a preset torsion angle.

[0012] S3. The rotating module drives the second clamping element to rotate the T2 magnetic ring, causing the first tap and the second tap to wrap around each other.

[0013] An automatic twisting device for network transformer taps includes a machine base, a first clamping element, a second clamping element, a third clamping element, a moving module, and a rotating module.

[0014] The third clamping element is used to clamp the first tap;

[0015] The first clamping element is used to clamp the third tap;

[0016] The second clamping element is movable and rotatably arranged relative to the machine base; the second clamping element is used to clamp the T2 magnetic ring;

[0017] The moving module is used to drive the second clamping element to move the T2 magnetic ring away from the first clamping element and the third clamping element;

[0018] The rotating module is used to drive the second clamping element to rotate relative to the machine base so that the first tap connected to the T2 magnetic ring is wound with the second tap.

[0019] Preferably, a limiting pneumatic gripper is also provided, and a limiting channel is formed between the two gripping parts of the limiting pneumatic gripper;

[0020] When the opening size of the limiting channel is smaller than the diameter of the T2 magnetic ring, it can prevent the T2 magnetic ring from passing through the limiting channel;

[0021] The first clamping element, the second clamping element, and the limiting pneumatic gripper are arranged in sequence; the third clamping element is movable relative to the machine tool along the arrangement direction of the three.

[0022] Preferably, the moving module includes a moving base and a linear moving element; the moving base is laterally movable relative to the machine tool; the linear moving element is used to drive the moving base to move laterally relative to the machine tool; and the second clamping element is rotatably mounted on the moving base.

[0023] Preferably, the rotating module is mounted on the movable seat and is drive-connected to the second clamping element.

[0024] Preferably, the rotating module includes a rotating shaft rotatably mounted on the movable seat and a drive motor for driving the rotating shaft to rotate, and the second clamping element is fixedly mounted on the rotating shaft.

[0025] Preferably, a lifting cylinder is fixedly installed on the machine base below the limiting gripper, and the limiting gripper is fixedly installed on the cylinder shaft of the lifting cylinder.

[0026] Preferably, a fourth clamping element is also provided, with the first clamping element, the second clamping element, the limiting pneumatic gripper and the fourth clamping element arranged in sequence.

[0027] Preferably, the linear motion element is a cylinder.

[0028] Preferably, the first clamping element, the second clamping element, and the third clamping element are all pneumatic grippers.

[0029] Compared with the prior art, the present invention provides an automatic twisting device for network transformer taps, which has the following significant advantages:

[0030] By setting the first and third clamping elements to stably clamp the third and first taps respectively, reliable positioning of the taps during the twisting process can be ensured. The second clamping element can firmly clamp the T2 magnetic ring, and in conjunction with the moving module, it drives the T2 magnetic ring to move away from the first and third clamping elements. This design allows the first and second taps to form an angle that facilitates twisting and winding, providing an ideal initial posture for subsequent winding actions and effectively avoiding winding disorder or uneven force caused by improper tap positioning.

[0031] Based on this, the rotating module drives the second clamping element to rotate relative to the machine platform, which in turn drives the first and second taps to precisely complete the winding action, realizing the automated operation of tap winding. This automation method not only significantly improves production efficiency and eliminates reliance on manual operation, but also ensures the consistency of tap winding for each product through precise control of the mechanical structure, reducing quality fluctuations caused by human error, significantly improving the product qualification rate and performance stability of network transformers, and better meeting the requirements of large-scale production and high quality.

[0048] See Figures 1-8An automatic twisting device for network transformer taps includes a machine base 10, a first clamping element 20, a second clamping element 30, a third clamping element 60, a moving module 70, and a rotating module 80. The third clamping element 60 is used to clamp a first tap 101. The first clamping element 20 is used to clamp a third tap 103. The second clamping element 30 is movable and rotatably disposed relative to the machine base 10. The second clamping element 30 is used to clamp a T2 magnetic ring 120. The moving module 70 is used to drive the second clamping element 30 to move the T2 magnetic ring 120 away from the first clamping element 20 and the third clamping element 60. The rotating module 80 is used to drive the second clamping element 30 to rotate relative to the machine base 10 so that the first tap 101 and the second tap 102 connected to the T2 magnetic ring 120 are wound together.

[0049] The working principle of the automatic torsion device for the network transformer taps is as follows:

[0050] During operation, the first clamping element 20 clamps and fixes the third tap 103, while the third clamping element 60 clamps the first tap 101. Through their combined action, a stable positioning foundation is provided for the taps. The second clamping element 30 precisely clamps the T2 magnetic ring 120. At this time, the first tap 101 and the second tap 102 connected to the T2 magnetic ring 120 are in their natural state.

[0051] Subsequently, the moving module 70 drives the second clamping element 30 to move the T2 magnetic ring 120 away from the first clamping element 20 and the third clamping element 60. During this process, the first tap 101 and the second tap 102 are gradually pulled to form an angle that facilitates twisting and winding, thus preparing the posture for the subsequent winding action.

[0052] When the first tap 101 and the second tap 102 are at a preset angle, preferably 30 to 40°, the rotating module 80 drives the second clamping element 30 to rotate relative to the machine base 10. Since the second clamping element 30 and the T2 magnetic ring 120 are held and fixed, the T2 magnetic ring 120 rotates together with it, thereby driving the first tap 101 and the second tap 102 connected to it to rotate and wind around each other based on the angle formed between them, and finally complete the twisting and winding action of the first tap 101 and the second tap 102.

[0053] See Figure 4The system also includes a fifth clamping element 90 and a limiting pneumatic gripper 40. A limiting channel 410 is formed between the two clamping portions of the limiting pneumatic gripper 40. When the opening size of the limiting channel 410 is smaller than the diameter of the T2 magnetic ring 120, it can prevent the T2 magnetic ring 120 from passing through the limiting channel 410. The first clamping element 20, the second clamping element 30, and the limiting pneumatic gripper 40 are arranged sequentially. The third clamping element 60 is movable relative to the machine base 10 along the arrangement direction of the three elements. During operation, when the winding assembly of the transformer production equipment conveys the coil to a preset position, the first tap 101 of the coil is clamped by the third clamping element 60, and the third tap 103 is clamped and fixed by the fifth clamping element 90. Since the third clamping element 60 is movable relative to the machine tool 10 along the arrangement direction of the first clamping element 20, the second clamping element 30, and the limiting gripper 40, and in addition to fixing the first tap 101, it can also drive the entire coil to move. Therefore, under the movement of the third clamping element 60, the coil will pass through the positions of the first clamping element 20, the second clamping element 30, and the limiting gripper 40 in sequence. During this process, the first clamping element 20, the second clamping element 30, and the limiting gripper 40 can be moved or their clamping parts can be opened to allow the third clamping element 60 to pass through. After the third clamping element 60 passes through, the two clamping parts of the limiting gripper 40 close to form a limiting channel 410. Since the opening size of the limiting channel 410 is smaller than the diameter of the T2 magnetic ring 120, it can prevent the T2 magnetic ring 120 from passing through, thereby constraining the T2 magnetic ring 120. Subsequently, the moving second clamping element 30 moves to the preset position to clamp the T2 magnetic ring 120, while the first clamping element 20 clamps and fixes the third tap 103, completing the automatic delivery of the coil and preparing for the subsequent twisting process.

[0054] See Figure 5 Regarding the movement setting of the third clamping element 60, specifically its movement setting is on the gantry 110. The gantry 110 is equipped with a linear module for driving the movement of the third clamping element 60. The linear module adopts an existing linear motor.

[0055] See Figure 4 and Figure 6 A lifting cylinder 400 is fixedly installed on the machine base 10 below the limiting gripper 40. The limiting gripper 40 is fixedly installed on the cylinder shaft of the lifting cylinder 400, and the cylinder shaft can drive the limiting gripper 40 to achieve lifting and lowering. This design can flexibly adjust the height of the limiting gripper 40. When the third clamping element 60 carries the coil through, the limiting gripper 40 can be raised to avoid it. After it passes, the limiting gripper 40 is lowered so that the limiting channel 410 formed by the two clamping parts closes can accurately constrain the T2 magnetic ring 120, ensuring the orderly conveying of the coil and subsequent processes.

[0056] See Figure 5 and Figure 6 The system also includes a fourth clamping element 50, a fifth clamping element 90, a first clamping element 20, a second clamping element 30, and a limiting pneumatic gripper 40, arranged sequentially. The fourth clamping element 50, along with the first clamping element 20, the second clamping element 30, and the limiting pneumatic gripper 40, primarily serves to temporarily clamp the first tap 101. When the third clamping element 60 needs to move closer to the T2 magnetic ring 120 to adjust the clamping point of the first tap 101, the fourth clamping element 50 can temporarily fix the first tap 101, ensuring its stable position. After the third clamping element 60 moves to the target position and firmly clamps the first tap 101 (the clamping position is closer to the T2 magnetic ring 120), the fourth clamping element 50 releases, thus providing a better clamping foundation for the subsequent twisting and winding of the first tap 101 and the second tap 102, ensuring precise and efficient winding operations.

[0057] Specifically, regarding the fourth clamping element 50, it can avoid the third clamping element 60 by opening its clamping part, i.e., by using a parallel pneumatic gripper, or by moving relative to the machine tool 10. The movement setting can be synchronized with the second clamping element 30, i.e., it can be set on the moving module 70 and moved by the moving module 70.

[0058] See Figure 7 The moving module 70 includes a moving base 710 and a linear moving element 720. The moving base 710 is laterally movable relative to the machine base 10. The linear moving element 720 drives the moving base 710 to move laterally relative to the machine base 10. The second clamping element 30 is rotatably mounted on the moving base 710. The linear moving element 720 can stably drive the moving base 710 to move laterally relative to the machine base 10, while the second clamping element 30 is rotatably mounted on the moving base 710, so that the moving base 710 can drive the second clamping element 30 and the clamped T2 magnetic ring 120 to move synchronously and smoothly, ensuring that the movement process is precise and controllable. This structural design can reliably drive the second clamping element 30 to move to the target position. At this time, the first clamping element 20, the second clamping element 30, and the third clamping element 60 form a triangle. The first tap 101 and the second tap 102 are in the angle state preset by the present invention; that is, the angle formed by the two straight lines from the second clamping element 30 to the first clamping element 20 and the third clamping element 60 provides an ideal initial posture for subsequent twisting and winding.

[0059] See Figure 7The rotating module 80 is mounted on the movable base 710 and is tractively connected to the second clamping element 30. The rotating module 80 includes a rotating shaft 810 rotatably mounted on the movable base 710 and a drive motor 800 for driving the rotating shaft 810 to rotate. The second clamping element 30 is fixedly mounted on the rotating shaft 810. The drive motor 800 drives the rotating shaft 810 to rotate, and since the second clamping element 30 is fixed on the rotating shaft 810, the rotation of the rotating shaft 810 drives the second clamping element 30 to rotate synchronously, thereby driving the T2 magnetic ring 120 clamped by it to rotate, realizing the twisting and winding of the first tap 101 and the second tap 102. Simultaneously, the rotating module moves together with the movable base 710, and can cooperate with the movable module to ensure that the twisting action is performed accurately in a preset posture.

[0060] In this invention, the linear motion element 720 is a cylinder.

[0061] In this invention, the first clamping element 20, the second clamping element 30, the third clamping element 60, the fourth clamping element 50, and the fifth clamping element 90 are all pneumatic grippers.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
