Abstract
Description
Technical Field
[0001] The present application relates to the technical field of amorphous strip winding, and in particular to a method for adjusting the tension of an amorphous strip. Background Art
[0002] Amorphous alloys are green and energy-efficient materials, characterized by energy-saving manufacturing technology and applications. my country has established relatively mature ultra-thin amorphous strip production capabilities and a broad market for applications. In particular, amorphous three-dimensional coil transformers, using ultra-thin amorphous strip as the core material, are widely used in the power distribution sector due to their energy and material savings, low noise, and minimal magnetic flux leakage.
[0003] The production of amorphous three-dimensional wound transformer cores requires that the amorphous strips be intact without tears or folds to ensure that the amorphous strips are tightly wound, the cores are seamless, and the air gap loss is small. Therefore, the tension of the ultra-thin amorphous strips themselves is strictly controlled during the transmission process.
[0004] There is a lack of research on the ultra-thin amorphous strip conveying process and existing conveying equipment. The traditional ultra-thin amorphous strip conveying method only uses a simple double-roller conveying method, which cannot achieve the control of the tension of the ultra-thin amorphous strip during the winding process.
[0005] Application Contents
[0006] Based on this, it is necessary to provide a method for adjusting the tension of an amorphous strip to address the problem that the tension in the winding process of the amorphous strip cannot be controlled.
[0007] A method for adjusting the tension of an amorphous strip comprises the following steps:
[0008] Connecting one end of the amorphous strip to the winding head and winding it to the outer periphery of the winding head;
[0009] A first support roller and a second support roller for supporting the amorphous strip are arranged at intervals on a transmission path of the amorphous strip, and the second support roller is located between the first support roller and the winding head;
[0010] During the winding process of the amorphous strip, the second support roller is controlled to move relative to the winding head along the first direction to change the winding angle of each layer of amorphous strip wound onto the winding head. The first direction is arranged to intersect with the thickness direction of the amorphous strip.
[0011] In one embodiment, after changing the winding angle of the amorphous strip wound onto the winding head, the method further comprises:
[0012] Detect the tension of each layer of amorphous strip wound onto the winding head;
[0013] Determine whether the tension of each layer of amorphous strip is equal to the set tension of each layer of amorphous strip;
[0014] If so, control the second support roll to stop.
[0015] In one embodiment, before determining whether the tension of each layer of amorphous strip is equal to the set tension of each layer of amorphous strip, it further includes:
[0016] Obtain the set tension of each layer of amorphous strip;
[0017] Among them, the set tension of each layer of amorphous strip decreases sequentially from the inner layer to the outer layer.
[0018] In one embodiment, obtaining the set tension of each layer of amorphous strip specifically includes:
[0019] Set the first set tension of the innermost layer of amorphous strip wound on the winding head;
[0020] Set the second set tension of the outermost layer of amorphous strip wound on the winding head;
[0021] The absolute value of the difference between the set tensions of each layer of amorphous strip and the set tension of the adjacent layer of amorphous strip is (the first set tension - the second set tension) / the total number of winding layers of the amorphous strip on the winding head.
[0022] In one embodiment, sequentially arranging the first support roll and the second support roll on the transmission path of the amorphous strip specifically includes:
[0023] The first support roll and the second support roll are arranged at intervals along the transmission path of the amorphous strip, and it is controlled that the first support roll and the second support roll support on both sides in the thickness direction of the amorphous strip.
[0024] In one embodiment, changing the winding angle of the amorphous strip wound on the winding head specifically includes:
[0025] Obtain the winding radius of the amorphous strip;
[0026] When the winding radii are different, control the second support roll to move relative to the winding head in the first direction.
[0027] In one embodiment, obtaining the winding radius of the amorphous strip on the winding head specifically includes:
[0028] Obtain the number of winding layers;
[0029] The winding radius is the radius of the winding head + the number of winding layers × the thickness of the amorphous strip × the filling coefficient.
[0030] In one embodiment, controlling the second support roll to move relative to the winding head in the first direction specifically includes:
[0031] Connect one axial end of the second support roll to the driving structure on the support device;
[0032] The driving structure drives the second support roller to move along a first direction on the support device.
[0033] In one embodiment, changing the winding angle at which the amorphous strip is wound onto the winding head further includes:
[0034] Controlling the movement of the winding head relative to the second support roller.
[0035] In one embodiment, controlling the movement of the winding head relative to the second support roller to change the winding angle at which each layer of the amorphous strip is wound onto the winding head specifically includes:
[0036] Controlling the movement of the winding head along the transmission direction of the amorphous strip, in a direction approaching or away from the second support roller.
[0037] The above amorphous strip tension adjustment method drives the local movement of the amorphous strip supported on itself along the first direction by setting the second support roller to move relative to the first support roller along the first direction, thereby changing the winding angle at which the amorphous strip is wound onto the winding head. Through the change of the winding angle, the tension during the winding process of the amorphous strip is adjusted in real time. During the actual winding process, the winding angle can be adaptively adjusted according to the measurement and feedback of the actual real-time tension to reach the target tension value.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.
[0056] As described in the background art, the production of an amorphous three-dimensional wound transformer core requires that the amorphous strip be intact without tearing or folding to ensure that the amorphous strip is wound tightly, the core has no joints, and the air gap loss is small. Therefore, strict control is required for the self-tension of the ultra-thin amorphous strip during the transmission process. The research on the transmission process of ultra-thin amorphous strips and existing transmission equipment are relatively lacking. Measures for detecting, feedback, and adjustment of the self-tension of ultra-thin amorphous strips during the transmission process cannot be achieved. It is easy to make the transmission tension of ultra-thin amorphous strips unstable: if the strip bears too tight or uneven tension on both sides during the strip transmission process, it will cause the ultra-thin amorphous strip to be prone to tearing or folding; if the strip transmission tension is loose, it will seriously affect the strip transmission efficiency and subsequent processing.
[0057] To solve the above problems, refer to Figure 1 and Figure 2, an embodiment of the present application provides a method for adjusting the tension of an amorphous strip, which is used to adjust the tension during the winding process of each layer of the amorphous strip 200 when the amorphous strip 200 is wound to form a three-dimensional wound transformer core.
[0058] In one embodiment, refer to Figure 2 , the method for adjusting the tension of the amorphous strip specifically includes the following steps:
[0059] S10. Connect one end of the amorphous strip 200 to the winding head 100 and wind it around the outer periphery of the winding head 100;
[0060] S20. Intermittently arrange a first support roller 310 and a second support roller 320 for supporting the amorphous strip 200 on the transmission path of the amorphous strip 200, and the second support roller 320 is located between the first support roller 310 and the winding head 100;
[0061] S30. During the winding process of the amorphous strip 200, control the second support roller 320 to move relative to the winding head 100 along the first direction L1 to change the winding angle of each layer of the amorphous strip 200 wound on the winding head 100, and the first direction L1 is arranged to intersect with the thickness direction of the amorphous strip 200.
[0062] The amorphous strip 200 can be set in a roll. Connect one end of the roll of the amorphous strip 200 to the winding head 100, and control the winding head 100 to rotate self - sufficiently to gradually peel the amorphous strip 200 from the roll of the amorphous strip 200 and wind it layer by layer on the winding head 100.
[0063] Intermittently arrange a first support roller 310 and a second support roller 320 for supporting the amorphous strip 200 on the transmission path of the amorphous strip 200. The amorphous strip 200 will first pass through the first support roller 310, then pass through the second support roller 320 and be wound around the outer periphery of the winding head 100 as the winding head 100 rotates. After the relative positions among the first support roller 310, the second support roller 320 and the winding head 100 are fixed, the winding angle of each layer of the amorphous strip 200 wound on the winding head 100 is certain.
[0064] The winding angle refers to the angle formed between the tangent direction of the winding head 100 during the winding process of each layer of the amorphous strip 200. Control the second support roller 320 to move relative to the first support roller 310 along the first direction L1. The second support roller 320 will drive the amorphous strip 200 supported thereon to move, thereby changing the angle between the amorphous strip 200 between the second support roller 320 and the first support roller 310 and the amorphous strip 200 between the second support roller 320 and the winding head 100, as well as the winding angle of the amorphous strip 200 wound on the winding head 100.
[0065] Thus, by setting the second support roller 320 to move relative to the first support roller 310 along the first direction L1, the amorphous strip 200 supported thereon is driven to move locally along the first direction L1 and the winding angle of the amorphous strip 200 wound around the winding head 100 is changed. By changing the winding angle, the tension during the winding process of the amorphous strip 200 is adjusted in real time. During the actual winding process, according to the measurement and feedback of the actual real-time tension, the winding angle of each layer of the amorphous strip 200 can be adaptively adjusted to reach the target tension value.
[0066] It can be understood that the required winding angles of each layer of the amorphous strip 200 during the winding process are different. In order to ensure that the amorphous strip 200 is wound tightly, the iron core has no seams, and the air gap loss is small, it is necessary to control the tension to be the maximum when the winding radius is the smallest, that is, when winding the first layer, and control the tension to be the minimum when the winding sleeve radius is the largest, that is, when winding the last layer. Thus, by setting the winding, the maximum tension of the innermost layer and the minimum tension of the outermost layer are achieved.
[0067] In one embodiment, referring to Figure 3 , after changing the winding angle of the amorphous strip 200 wound around the winding head 100, it further includes:
[0068] S40. Detect the tension of each layer of the amorphous strip 200 wound around the winding head 100;
[0069] S60. Determine whether the tension of each layer of the amorphous strip 200 is equal to the set tension of each layer of the amorphous strip 200; if so, control the second support roller 320 to stop.
[0070] A detection device can be set to detect the winding tension of each layer of the amorphous strip 200 during the winding process of the amorphous strip 200. It can be understood that the set tension of the innermost layer of the amorphous strip 200 must be greater than the set tension of the outermost layer of the amorphous strip 200. During the entire winding process, as the number of winding layers increases, the set tension of each layer of the amorphous strip 200 gradually decreases. When it is detected that the tension of each layer of the amorphous strip 200 is not equal to the set tension, the movement of the second support roller 320 is controlled to change the winding angle, so as to adjust the tension to the set tension and then stop the movement of the second support roller 320.
[0071] Thus, it is possible to quickly adjust the tension of each layer of the amorphous strip 200 during the winding process of the amorphous strip 200.
[0072] In one embodiment, referring to Figure 4 , sequentially arranging the first support roller 310 and the second support roller 320 on the transmission path of the amorphous strip 200 specifically includes:
[0073] S21. Set the first support roller 310 and the second support roller 320 at intervals along the transmission path of the amorphous strip 200, and control the first support roller 310 and the second support roller 320 to support on both sides in the thickness direction of the amorphous strip 200.
[0074] Support the first support roller 310 and the second support roller 320 on both sides in the thickness direction of the amorphous strip 200. When the second support roller 320 moves relative to the winding head 100 along the first direction L1, the second support roller 320 also moves relative to the first support roller 310, so that the first support roller 310 forms a fixed support structure and the second support roller 320 forms a floating support structure. By changing the support position of the floating support structure for the amorphous strip 200, the winding angle is changed.
[0075] Understandably, referring to Figure 1 , Figure 1 The positions of the second support roller 320 when winding the innermost amorphous strip 210 and the positions of the second support roller 320 when winding the outermost amorphous strip 220 are respectively shown. It can be seen that the second support roller 320 has a position movement along the first direction L1.
[0076] In one embodiment, referring to Figure 5 , specifically changing the winding angle of the amorphous strip 200 wound onto the winding head 100 includes:
[0077] S31. Obtain the winding radius of the amorphous strip 200; when the winding radii are different, control the second support roller 320 to move relative to the winding head 100 along the first direction L1.
[0078] When multiple layers of the amorphous strip 200 are wound around the outer circumference of the winding head 100, there is a direct proportional relationship between the winding radius and the winding layer number. The more the winding layer number, the larger the winding radius. When the winding radii are different, the set tensions required for this layer of the amorphous strip 200 are also different.
[0079] In one embodiment, referring to Figure 6 , specifically obtaining the winding radius of the amorphous strip 200 on the winding head 100 includes:
[0080] S311. Obtain the winding layer number. The winding radius is the radius of the winding head 100 + the winding layer number × the thickness of the amorphous strip 200 × the filling coefficient.
[0081] Set the innermost amorphous strip 200 wound onto the amorphous strip 200 as the first layer (i.e., Figure 1At the position where the middle 210 is located, it is wound in sequence and the winding layers are stacked, so that the winding radius gradually increases. Finally, the winding radius of each layer of amorphous ribbon 200 is equal to the radius dimension of the winding head 100 itself plus the thickness of the amorphous ribbon 200 stacked on the winding head 100.
[0082] It can be understood that if the radius of the winding head 100 changes, the winding radius of each layer of amorphous ribbon 200 on the winding head 100 also changes accordingly.
[0083] In one embodiment, referring to Figure 7 , controlling the second support roller 320 to move relative to the winding head 100 along the first direction L1 specifically includes:
[0084] S32. Connect one axial end of the second support roller 320 to the driving structure on the support device 300;
[0085] The driving structure drives the second support roller 320 to move along the first direction L1 on the support device 300.
[0086] In this way, by controlling the driving structure to drive the second support roller 320 to move, the reciprocating movement of the second support roller 320 in the first direction L1 is realized.
[0087] In one embodiment, referring to Figure 8 , before determining whether the tension of each layer of amorphous ribbon 200 is equal to the set tension of each layer of amorphous ribbon 200, it further includes:
[0088] S50. Obtain the set tension of each layer of amorphous ribbon 200;
[0089] Among them, the set tension of each layer of amorphous ribbon 200 decreases sequentially from the inner layer to the outer layer.
[0090] During the entire winding process, as the number of winding layers increases, the set tension of each layer of amorphous ribbon 200 gradually decreases. When it is detected that the tension of each layer of amorphous ribbon 200 is not equal to the set tension, the winding angle is changed by controlling the movement of the second support roller 320, so as to adjust the tension to the set tension and then stop the movement of the second support roller 320.
[0091] In one embodiment, referring to Figure 9 , obtaining the set tension of each layer of amorphous ribbon 200 specifically includes:
[0092] S51. Set the first set tension of the innermost amorphous ribbon 210 wound on the winding head 100; set the second set tension of the outermost amorphous ribbon 220 wound on the winding head 100;
[0093] The absolute value of the difference between the set tensions of each layer of amorphous strip 200 relative to the adjacent layer of amorphous strip 200 is (the first set tension - the second set tension) / the total number of winding layers of the amorphous strip 200 on the winding head 100.
[0094] Specifically, the first set tension is the maximum tension, the second set tension is the minimum tension, the set tension of the second layer of amorphous strip 200 adjacent to the innermost layer is the second set tension + (the first set tension - the second set tension) / the total number of winding layers of the amorphous strip 200 on the winding head 100, and the set tension of the third layer of amorphous strip 200 is the second set tension + 2 × [(the first set tension - the second set tension) / the total number of winding layers of the amorphous strip 200 on the winding head 100], and so on.
[0095] In one embodiment, referring to Figure 10 , changing the winding angle of the amorphous strip 200 wound onto the winding head 100 further includes:
[0096] S33. Control the movement of the winding head 100 relative to the second support roller 320.
[0097] It can be understood that for the same layer of amorphous strip 200 wound onto the winding head 100, when the winding head 100 is closer to the second support roller 320, the winding angle is larger. Thus, by controlling the movement of the winding head 100, the winding angle can be adjusted to be smaller or larger.
[0098] In one embodiment, controlling the movement of the winding head 100 relative to the second support roller 320 specifically includes:
[0099] S331. Control the movement of the winding head 100 along the transmission direction L2 of the amorphous strip 200, towards or away from the second support roller 320.
[0100] Thus, by adjusting the forward and backward movement of the winding head 100 relative to the second support roller 320, the winding angle of the amorphous strip 200 wound onto the winding head 100 can be adjusted.
[0101] In one embodiment, when the amorphous strip 200 is wound, multiple segments of amorphous strip 200 can be provided, and each segment of amorphous strip 200 can be wound into multiple layers on the winding head 100. After the first segment of amorphous strip 200 is completely wound onto the winding head 100, the head end of the second segment is connected to the tail end of the first segment of amorphous strip 200 to achieve superimposed winding, and the subsequent third, fourth segments of amorphous strip 200 are carried out in the same way.
[0102] Further, the present application also provides a length calculation formula for each section of the amorphous strip 200 wound onto the winding head 100. Regarding the winding head 100 as a cylindrical shape, specifically, the length of the first section of the amorphous strip 200 is specifically L1 = 2π(R + h / 2) × (h / d).
[0103] Wherein, L1 refers to the length of the first section of the amorphous strip 200, π refers to the number of pi, R refers to the radius of the winding head 100, h refers to the total winding stack thickness of the first section of the amorphous strip 200 wound onto the winding head 100, d refers to the thickness of the strip, 2π(R + h / 2) refers to the average circumference of the multi-layer amorphous strip 200 of the first section of the amorphous strip 200 wound onto the winding head 100, and h / d is the total number of winding layers of the first section of the amorphous strip 200 on the winding head 100, and thus the length value of the first section of the amorphous strip 200 can be obtained.
[0104] It can be understood that the second section of the amorphous strip 200 is entirely wound around the outer circumference of the first section of the amorphous strip 200. Then, when calculating the length of the second section of the amorphous strip 200, R refers to the radius of the winding head 100 plus the total winding stack thickness h of the first section of the amorphous strip 200 wound onto the winding head 100, as the winding basis of the second section of the amorphous strip 200.
[0105] In this way, for the amorphous strip tension adjustment method provided by the present application, by adjusting the movement of the second support roller 320 in the first direction L1, or controlling the front and rear positions of the winding head 100 in the transmission direction L2 of the amorphous strip 200, the winding angle of each layer of the amorphous strip 200 wound onto the winding head 100 is adjusted, so as to adjust the tension during the winding process of the amorphous strip 200 in real time. During the actual winding process, according to the measurement and feedback of the actual real-time tension, the winding angle of each layer of the amorphous strip 200 can be adaptively adjusted to reach the target tension value.
[0106] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0107] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
