DETAILED DESCRIPTION

[0036] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0037] The first implementation method:

[0038] Figure 1 - Figure 8 The high-frequency transformer automatic winding device is shown, which includes a device body 1, a wire drawing guide frame 11 arranged at the upper end of the device body 1, and a control box 14 arranged at the lower end of the device body 1. A front wire drawing structure 12 and a rear wire drawing structure 13 located on the left side of the front wire drawing structure 12 are fixedly installed in the wire drawing guide frame 11. A tension adjustment support plate 2 is installed at the right end of the rear wire drawing structure 13. An adjustment rod 3 is connected to the lower end of the tension adjustment support plate 2. An adjustment steering rod 4 is rotatably connected to the front end of the adjustment steering rod 4. An adaptive wire drawing component 5 that cooperates with the rear wire drawing structure 13 is rotatably connected to the lower end of the adjustment steering rod 4.

[0039] The control box 14 is equipped with a tension adjustment auxiliary system, which includes a tension adjustment processing unit, the input end of which is connected to a winding parameter setting unit and a winding instruction acquisition unit, and the output end of which is connected to a wire drawing tension adjustment unit;

[0040] The input end of the winding parameter setting unit is connected to the signal input end set in the control box 14, the input end of the winding instruction acquisition unit is connected to the automatic winding control system carried in the control box 14, and the output end of the wire pulling tension adjustment unit is connected to the tension adjustment support plate 2.

On the other hand, while the winding head produces wire arrangement and winding actions, by adjusting the rotation of the steering rod 4 and the adaptive wire pulling component 5, the tension can be effectively adaptively adjusted according to the change of action, thereby effectively ensuring the tension adjustment accuracy, ensuring the effectiveness of the rear wire pulling structure 13 on the copper wire 15, and effectively improving the consistency of the tension of the copper wire 15 during the winding process. While promoting winding efficiency and improving winding quality, the economic benefits of the device body 1 in the application process are effectively improved.

[0041] It should be noted that the automatic winding control system is an existing technology, which can adjust and control the mechanical transmission system and electrical control system in the device body 1, and can receive data from the sensor, so as to realize automatic control and coordination during the winding process of the device body 1. It is directly quoted here, and no changes are made to the structure and principle of the automatic winding control system, so no further elaboration will be made.

[0042] Figure 3 - Figure 8 The rear wire drawing structure 13 is shown to include a plurality of rear wire drawing barrels 131 embedded in the left inner wall of the wire drawing guide frame 11, a rear wire drawing seat 132 located on the right side of the rear wire drawing barrel 131 is fixedly installed on the inner wall of the wire drawing guide frame 11, a plurality of rear wire drawing double barrel ears 133 matched with the rear wire drawing barrel 131 are fixedly installed on the upper end of the rear wire drawing seat 132, and the tension adjustment support plate 2, the adjustment rod 3, the adjustment steering rod 4 and the adaptive wire drawing assembly 5 are located between the rear wire drawing barrel 131 and the rear wire drawing double barrel ears 133;

[0043] A tension adjusting motor 21 is embedded on the upper right side of the rear pulling reel 131, and the upper output end of the tension adjusting motor 21 is fixedly connected to the tension adjusting support plate 2. The output end of the pulling tension adjusting unit is signal-connected to the tension adjusting motor 21. The tension adjusting motor 21 can drive the tension adjusting support plate 2 to produce a corresponding rotation at the right end of the rear pulling reel 131, and then can adjust the tension of the copper wire 15 according to the setting of the winding parameters. The pulling tension of the copper wire 15 by the rear pulling structure 13 is adjusted by intelligent control, which effectively improves the accuracy of tension adjustment and promotes the quality of subsequent winding.

[0044] Figure 5It is shown that an adjustment hole 22 is provided at the lower end of the tension adjustment support plate 2, an adjustment rod 3 is fixedly installed in the adjustment hole 22, an adaptation ball head 41 is fixedly connected to the rear end of the adjustment steering rod 4, and an adaptation ball groove 31 matching the adaptation ball head 41 is provided at the front end of the adjustment rod 3. The adjustment steering rod 4 can achieve rotational cooperation with the adjustment rod 3 through the adaptation ball head 41, so that when the copper wire 15 is subsequently driven by the winding head to move, the adaptive wire pulling component 5 can be pulled by the copper wire 15 to maintain the effectiveness of the traction tension adjustment, while ensuring the effectiveness of the wire pulling guidance and the smoothness of the movement of the copper wire 15, it promotes the maintenance of the tension, improves the range of adaptive adjustment of the tension of the copper wire 15 by the adaptive wire pulling component 5, further ensures the uniformity and tension of the winding, and improves the winding quality.

[0045] Figure 3 - Figure 8 The front end of the adjustable steering rod 4 is fixedly connected to a steering column head 42, and a waist groove is provided at the lower end of the steering column head 42. The adaptive wire pulling assembly 5 includes a steering platform 54 rotatably arranged in the waist groove, and an adaptive support rod 52 is fixedly connected to the steering platform 54 and is rotatably matched with the waist groove. The lower end of the adaptive support rod 52 is fixedly connected to an adaptive wire pulling drum 51, and the adaptive wire pulling drum 51 is respectively matched with the rear wire pulling double drum support ear 133 and the rear wire pulling drum 131. The adjustable steering rod 4 realizes the adaptive wire pulling assembly 5 through the coordination of the steering column head 42, the adaptive support rod 52 and the steering platform 54. The rotation connection of the wire pulling drum 51 can promote the function of the adaptive wire pulling drum 51 to adjust the tension of the copper wire 15 during the process of pulling the copper wire 15. When the winding head produces corresponding actions, the rotation of the adaptive wire pulling drum 51 can effectively ensure the smoothness of guiding the copper wire 15 and the continuity and stability of the tension, so as to achieve the effect of adaptive tension adjustment during the action of the winding head, which can effectively promote the winding quality while improving the winding efficiency and improve the economic benefits of the device body 1.

[0046] Figure 3 - Figure 8 It is shown that a wear-resistant bearing is embedded in the waist groove, and the inner ring of the wear-resistant bearing is fixedly connected to the steering platform 54. The cooperation between the wear-resistant bearing and the steering platform 54 can not only realize the rotation effect between the steering platform 54 and the steering column head 42, but also promote the flexibility of rotation, thereby promoting the smoothness of the adaptive tension adjustment and reducing the impact on the winding during the adaptive adjustment process.

[0047] Figure 3 - Figure 8It is shown that an adaptive wire pulling core barrel 53 is embedded in the adaptive wire pulling core barrel 53, and guiding outwardly expanded fillets 55 are provided at both ends of the adaptive wire pulling core barrel 53. The setting of the guiding outwardly expanded fillets 55 can further realize the smooth movement of the copper wire 15 in the adaptive wire pulling core barrel 53, and can also effectively ensure that when the adaptive wire pulling core barrel 51 generates an adaptively adjusted rotation, a smooth transition of the copper wire 15 in the adaptive wire pulling core barrel 53 is realized, thereby reducing the friction resistance generated in the wire pulling guiding process, ensuring the winding efficiency, and improving the winding quality.

[0048] Figure 1 - Figure 8 It is shown that during the application of the device body 1, the copper wire 15 is led out through the front wire drawing structure 12, the rear wire drawing double barrel lug 133, the adaptive wire drawing core barrel 53, and the rear wire drawing barrel 131, and then pulled to the winding head through the wire structure at the front end of the wire drawing guide frame 11. Then, the technician or staff inputs the data parameters about the winding into the winding parameter setting unit through the signal input end of the control box 14, including but not limited to the winding speed, winding tension and tension standard range and other data. Then, the winding parameter setting unit processes and converts these data and transmits them to the tension adjustment processing unit. The tension adjustment processing unit analyzes and processes these data, and then adjusts the tension. The section instruction is transmitted to the wire drawing tension adjustment unit, so that the wire drawing tension adjustment unit controls the tension adjustment motor 21 to start, and the tension adjustment motor 21 rotates, and drives the tension adjustment support plate 2 to rotate on the upper side of the right end of the rear wire drawing drum 131 through the output end, and then drives the adaptive wire drawing drum 51 to rotate through the linkage cooperation of the adjustment rod 3, the adjustment steering rod 4 and the adaptive support rod 52, and the adaptive wire drawing drum 51 pulls the copper wire 15 in the adaptive wire drawing core drum 53, so as to realize the tension tightening effect of the subsequent copper wire 15, ensure the tension of the copper wire 15 in the subsequent winding process, improve the tension stability of the copper wire 15 in the transportation process, and effectively improve the winding quality;

[0049] Then, when the device body 1 is started and the winding head performs the winding action, the distance between the winding head and the rear pulling structure 13 changes due to the change in the position of the winding head, which will cause the tension of the copper wire 15 acting on the adaptive pulling core barrel 53 to change. Since the adaptive pulling core barrel 51 is rotatably connected with the steering column head 42 through the adaptive support rod 52 and the steering platform 54, during the process of tension change, the adaptive pulling core barrel 51 can produce corresponding rotation under the action of the copper wire 15, and the adjusting steering rod 4 can further promote the range of tension adjustment by adapting to the rotation coordination of the ball head 41 and the adjusting rod 3, thereby ensuring the smooth transportation of the copper wire 15 in the adaptive pulling core barrel 53 while effectively realizing the adaptive adjustment of the tension change of the copper wire 15, ensuring the stability of the tension, thereby effectively promoting the uniformity of winding, improving the winding quality, and reducing the damage of the copper wire 15 during the transmission process, promoting the winding function guarantee effect, and improving the economic benefits of the device body 1.

[0050] Second implementation method:

[0051] Figure 1 - Figure 5 and Fig. 9 - Fig.12 The high-frequency transformer automatic winding device is shown as a further improvement and supplement to the first embodiment, as an optional function and specification, to promote the intelligence and automation of the device body 1. Specifically, a tension sensing component 6 is further provided between the adaptive wire drawing barrel 51 and the adaptive wire drawing core barrel 53. The tension sensing component 6 includes a tension sensing nest 61 fixedly connected to the adaptive wire drawing barrel 51, a flexible sensing sleeve 62 fixedly connected to the tension sensing nest 61, and an adaptive wire drawing core barrel 53 fixedly connected to the flexible sensing sleeve 62;

[0052] A sensing cavity 63 is provided in the flexible sensing sleeve 62, and the inner walls on both sides of the sensing cavity 63 perpendicular to the radial direction are fixedly connected with a plurality of elastic shaping arc pieces 64, and the two elastic shaping arc pieces 64 at corresponding positions on the inner and outer sides are fixedly connected with a plurality of mutually cooperating sensing trigger columns 65 at one end thereof. The setting of the tension sensing component 6 can effectively increase the buffering effect of the adaptive wire pulling core tube 53 in the process of guiding and adjusting the tension of the copper wire 15, and can further promote the smoothness and accuracy of the adaptive tension adjustment. Through the effect of flexible buffering, the damage that may be caused to the copper wire 15 during the process of tension maintenance and adaptive adjustment is reduced, the surface quality is ensured, the deformation of the copper wire 15 during the process of tension maintenance and adaptive adjustment is avoided, the winding quality is ensured, and the safety of its application in subsequent transformers is promoted.

[0053] Figure 2It is shown that the input end of the tension adjustment processing unit is also connected to a tension abnormality feedback unit, and the input end of the tension abnormality feedback unit is signal-connected to the induction trigger column 65. The output end of the tension adjustment processing unit is also connected to a tension compensation unit, and the output end of the tension compensation unit is signal-connected to the wire tension adjustment unit. The setting of the induction trigger column 65 and the tension abnormality feedback unit can effectively realize the monitoring of the tension state, avoid the abnormality of excessive tension during the tension maintenance and adjustment process, effectively protect the copper wire 15, reduce the probability of damage to the copper wire 15, ensure the winding quality and its functional effectiveness, and the setting of the tension compensation unit can effectively realize the release compensation effect of the wire tension adjustment unit, and then realize the recovery and adjustment of the tension when the tension is abnormally excessive, thereby ensuring the effectiveness of the copper wire 15 in the subsequent winding process.

[0054] Figure 1 and Figure 2 It is shown that the output end of the tension adjustment processing unit is also connected to the abnormal wire pulling output unit, and the output end of the abnormal wire pulling output unit is respectively connected to the automatic winding control system mounted in the control box 14 and the alarm signal arranged on the device body 1. The setting of the abnormal wire pulling output end unit can effectively generate an alarm and pause the feedback of winding when the abnormal tension adjustment fails. On the one hand, it can avoid the loss of raw materials and damage to the device body 1 caused by continuous winding, and on the other hand, it can effectively remind the staff to take emergency response measures to reduce the losses caused by abnormalities.

[0055] Figure 2 It is shown that the input end of the tension adjustment processing unit is also connected to a tension adjustment verification unit, and the input end of the tension adjustment verification unit is connected to the tension abnormality feedback unit signal. The setting of the tension adjustment verification unit can effectively realize the verification of the effectiveness of the tension compensation unit regulation, can ensure the effectiveness of the tension abnormality recovery, and play a role in self-inspection and self-verification of the compensation regulation.

[0056] Figure 1 - Figure 5 and Fig. 9 - Fig.12It is shown that before the tension adjustment processing unit receives the winding parameters transmitted by the winding parameter setting unit and the tension adjustment processing unit performs command control on the wire drawing tension adjustment unit according to the winding parameters, the technician or production personnel needs to control the winding head to produce a reset action through the automatic winding control system to restore it to the position with the shortest distance between it and the rear wire drawing drum 131, so as to ensure that the transmission route of the copper wire 15 is the shortest at this time, and then the tension adjustment processing unit takes effect in controlling the wire drawing tension adjustment unit, so that it controls the tension adjustment motor 21 to rotate, adjusts the tension to the standard upper limit value range, and then in the subsequent operation of the device body 1, keeps the copper wire 15 and the adaptive wire drawing core drum 53 In the transmission state of contact with the inner wall, the winding head will change the distance between it and the rear drawing barrel 131 during the continuous movement, increasing the transmission route of the copper wire 15, which will cause the drawing tension of the copper wire 15 to increase continuously, and squeeze the inner wall of the adaptive drawing core barrel 53. The squeezing of the adaptive drawing core barrel 53 will be transmitted to the flexible sensing sleeve 62. The tension is buffered by the action of the flexible sensing sleeve 62 and the elastic shaping arc piece 64, and the rotation cooperation of the adaptive support rod 52 and the steering column head 42, and the rotation cooperation of the adaptive ball head 41 and the adjustment rod 3, so as to realize the function of adaptive tension adjustment rotation, release part of the tension, and avoid the problem of deformation of the copper wire 15 caused by excessive tension;

[0057] Then, in the process of continuous winding, the winding head continuously moves to increase the tension. After the adaptive wire drawing drum 51 generates the tension adaptive adjustment rotation, the tension is still too large to avoid the contact between the copper wire 15 and the adaptive wire drawing core drum 53, causing continuous squeezing pressure, causing the adaptive wire drawing core drum 53 and the flexible sensing sleeve 62 to deform, driving the elastic shaping arc piece 64 located on the inside to continuously approach the elastic shaping arc piece 64 located on the outside, so that the sensing trigger columns 65 at two corresponding positions are in abutment and contact, and the sensing trigger column 65 transmits the trigger signal to the tension abnormality feedback unit, and the tension abnormality feedback unit transmits the trigger signal to the tension adjustment processing unit and the tension adjustment verification unit respectively. At the same time, in this process, the automatic winding control system will transmit the execution status of its control of the winding head action to the winding instruction acquisition unit, and the winding The line instruction acquisition unit transmits data to the tension adjustment processing unit. The tension adjustment processing unit determines that the initial tension adjustment is too large according to the execution state of the winding and the trigger signal, and then transmits the adjustment compensation data to the tension compensation unit. The tension compensation unit processes and converts the tension compensation data, and then transmits it to the wire drawing tension adjustment unit, so that the wire drawing tension adjustment unit controls the tension adjustment motor 21 to rotate in the opposite direction of the previous tension adjustment according to the compensation data, and the rotation amplitude is smaller than the original tension adjustment amplitude, so that the tension adjustment motor 21 drives the tension adjustment support plate 2 to rotate in the opposite direction, so that the tension of the copper wire 15 is released by the adaptive wire drawing drum 51 and the adaptive wire drawing core drum 53 under the linkage of the adjustment rod 3 and the adjustment steering rod 4, so as to achieve the compensation adjustment effect on the tension and the release effect on the tension;

[0058] After the tension compensation is released, the automatic winding control system continues to control the device body 1 to work and produce the winding effect. The tension adjustment verification unit continuously monitors the data of the tension abnormality feedback unit. When the tension compensation is effective, the inductive trigger column 65 at the corresponding position at this time no longer produces the abutting triggering effect. Therefore, the tension abnormality feedback unit stops sending a trigger signal to the tension adjustment verification unit. Then, the tension adjustment verification unit transmits the verification data of the effective compensation to the tension adjustment processing unit. Therefore, the tension adjustment processing unit maintains the tension adjustment compensation effect at this time. When the tension compensation is invalid, the inductive trigger column 65 at the corresponding position at this time still produces The tension abnormality feedback unit continuously sends a trigger signal to the tension adjustment verification unit, and the tension adjustment verification unit transmits the verification data of invalid compensation to the tension adjustment unit. Therefore, the tension adjustment processing unit sends the compensation data to the tension compensation unit, so that the tension compensation unit sends the compensation data to the wire tension adjustment unit, and controls the tension adjustment motor 21 again, so that the tension adjustment motor 21 drives the tension adjustment support plate 2 to produce further reverse movement, so that the tension of the adaptive wire pulling drum 51 and the adaptive wire pulling core drum 53 on the copper wire 15 is released again under the linkage of the adjustment rod 3 and the adjustment steering rod 4;

[0059] Subsequently, the tension adjustment verification unit continues to verify the compensation data. After verifying that the compensation is invalid again, the tension adjustment processing unit transmits abnormal data to the wire pulling abnormal output unit after receiving the invalid verification data, so that the wire pulling abnormal output unit sends abnormal feedback to the automatic winding control system, so that the automatic winding control system can stop the control of the winding action in time to avoid the increase in the defective rate caused by continuous winding. The wire pulling abnormal output unit will also activate the alarm and issue an abnormal prompt to the staff, so that the staff can check and maintain the winding head and copper wire 15 in time, thereby reducing abnormal losses and improving the efficiency of abnormal handling.

[0060] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
