[0015] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0019] The technical solution of the present invention is further described below in conjunction with embodiments and drawings.

[0020] like Figure 1-4 As shown, a transformer coil winding device according to an embodiment of the present invention comprises: A base 1, on which a wire opening 1031 is provided along a first direction X for the coil to pass through; A first driving member 2, the first driving member 2 is disposed on the base 1; The transmission assembly 3 is slidably disposed on the base 1 along the second direction Y, and the power output end of the first driving member 2 is connected to the transmission assembly 3; A second driving member 4, the second driving member 4 is mounted on the transmission assembly 3, a mounting shaft 401 is provided at the power output end of the second driving member 4, the mounting shaft 401 extends along the second direction Y, and is used to drive the mounting shaft 401 to rotate; The guide assembly 5 includes a wire break sensor 501, which is disposed at the wire passing opening 1031 of the base 1 and is used to detect whether the coil passing through the wire passing opening 1031 is disconnected; A control component, the control component is electrically connected to the first driving member 2, the second driving member 4 and the disconnection sensor 501; The first direction X and the second direction Y are perpendicular to each other.

[0021] Specifically, the second driving member 4 is a motor.

[0022] Based on the above technical solution, the winding roller is installed on the mounting shaft 401, and the coil passes through the detection end of the broken wire sensor 501 and then passes through the wire passing port 1031 and is wound on the winding roller. At this time, the first drive member 2 drives the transmission component 3 to slide in the second direction Y, and the second drive member 4 drives the mounting shaft 401 to rotate, driving the winding roller to rotate. The control component controls the sliding speed of the transmission component 3 to match the rotation speed of the mounting shaft 401, so that the coil can be wound on the winding roller in sequence. When the broken wire sensor 501 detects that the coil is disconnected, the control component immediately sends a stop command to the first drive member 2 and the second drive member 4 to suspend the operation of the equipment to prevent material waste or winding errors caused by broken wires (the control component is not shown in the drawings in the specification).

[0023] The wire break sensor 501 is arranged at the wire passing port 1031, and can accurately monitor the state of the coil. Once a wire break is detected, a signal is immediately triggered. After receiving the signal from the wire break sensor 501, the control component can stop the operation of the first driving member 2 and the second driving member 4 in real time, so as to avoid the situation where the coil continues to operate after the wire break, resulting in material waste or equipment damage.

[0024] Preferably, the guide assembly 5 further comprises a detection cylinder 502 and a plurality of broken wire sensors 501, the detection cylinder 502 is coaxially arranged with the wire-passing opening 1031, a plurality of broken wire sensors 501 are arranged circumferentially at intervals on the inner wall of the detection cylinder 502, and the detection ends of the broken wire sensors 501 are all aligned with the axial position of the detection cylinder 502. The detection cylinder 502 is coaxially arranged with the wire-passing opening 1031, ensuring that the coil is always within the central range of the detection cylinder 502 during the winding process; the plurality of broken wire sensors 501 are arranged circumferentially at intervals along the inner wall of the detection cylinder 502, and the detection end of each broken wire sensor 501 is aligned with the axial position of the detection cylinder 502, so that the detection range covers the entire inner cavity of the detection cylinder 502, effectively avoiding the problem that a single sensor cannot cover all directions, realizing all-round detection of the coil, improving the sensitivity and accuracy of broken wire detection, and providing redundant detection capability, even if a single broken wire sensor 501 fails or misjudgments, the remaining broken wire sensors 501 can still work normally, thereby improving the reliability of the detection system. Through the coordinated work of the wire break sensors 501, the impact of environmental interference on the detection accuracy is reduced, and the stability of wire break monitoring during the winding process is guaranteed; the structure of the detection tube 502 is adapted to coils of different diameters and materials, ensuring the detection effect of the coils in various specifications of winding tasks. The multiple wire break sensors 501 distributed circumferentially can adapt to the slight deviation or swing that may occur in the coil during the winding process, ensuring that the wire break can be effectively detected even if the material is not completely in the center position.

[0025] More preferably, the guide assembly 5 further includes a wire ring 503, and the wire port 1031, the detection cylinder 502 and the wire ring 503 are arranged in sequence and at intervals, and the wire port 1031, the detection cylinder 502 and the wire ring 503 are arranged coaxially with each other. The coaxial design of the wire port 1031, the detection cylinder 502 and the wire ring 503, the wire port 1031 and the wire ring 503 radially limit the coil, effectively guide and organize the coil, ensure that the coil always remains in the specified path during the winding process, ensure that even if the coil is slightly offset, the wire break sensor 501 can still effectively detect the coil state, avoid missed detection or misjudgment due to path instability, further improve the alignment accuracy of the coil path, and avoid interference with the detection and winding process caused by coil offset or swing.

[0026] More preferably, the transmission assembly 3 includes a rocker 301, a transmission slot 302, a transmission arm 303, and a slide 304. The base 1 includes a seat body 101, a connecting arm 102, and a fixed plate 103. One end of the connecting arm 102 is connected to the seat body 101, and the other end is connected to the fixed plate 103. The fixed plate 103 is provided with a guide wheel group 104. The first driving member 2 is arranged on the connecting arm 102. The power output end of the first driving member 2 passes through the fixed plate 103 along the first direction X and is connected to one end of the rocker 301, so as to drive the rocker 301 to rotate.

[0027] Specifically, the first driving member 2 is a motor.

[0028] Based on the above technical solution, the first driving member 2 drives the rocker 301 to rotate, the plug-in portion 3011 of the rocker 301 slides relative to the transmission groove 302, and the transmission arm 303 is slidably set on the guide wheel group 104, thereby pushing the transmission groove 302 and the transmission arm 303 to slide on the guide wheel group 104. Since the length of the rocker 301 is smaller than the distance from the power output end of the first driving member 2 to the guide wheel group 104, that is, the rotation of the rocker 301 is not restricted by the position of the guide wheel group 104, the rotation of the rocker 301 is converted into the sliding of the transmission arm 303, thereby driving the sliding of the slide 304.

[0029] Through the cooperation of the rocker 301, the plug-in part 3011 and the transmission groove 302, the rotational power of the first drive member 2 is efficiently converted into linear motion, reducing unnecessary loads, and the first drive member 2 does not need to perform complex position control, thereby reducing the control difficulty of the control component, reducing the energy consumption and wear of the first drive member 2 during the motion conversion process, and extending the service life of the first drive member 2.

The two transmission arms 303 are respectively arranged on both sides of the transmission slot 302 in the second direction Y, so that the power is transmitted to the slide 304 more evenly, avoiding the deviation or tilt caused by the unilateral force in the single transmission arm 303 structure; the force of the slide 304 is transmitted to the guide wheel group 104 through the two transmission arms 303, so as to maintain the stability of the movement of the slide 304 and effectively avoid the swing or deviation that may be caused by the unilateral support design; the two guide wheel groups 104 are respectively arranged on both sides of the transmission slot 302, and are slidably supported one by one with the transmission arms 303, so as to ensure that the transmission arm 303 always maintains a stable and smooth straight sliding trajectory during operation.

The transmission arm 303 abuts between the two guide wheels 1041, forming an upper and lower clamping structure, which effectively prevents the transmission arm 303 from deflecting or tilting during the sliding process, ensuring the smoothness of the sliding. Preventing shaking and jumping: The two guide wheels 1041 are arranged at intervals along the third direction Z, so that the transmission arm 303 is always evenly supported and constrained, avoiding the shaking or jumping phenomenon caused by uneven force in the single guide wheel 1041 design.

The slide bars 105 are arranged at intervals along the first direction X and pass through the sliders 106 at the bottom of the slide 304, so that the slide 304 is always supported at multiple points during the sliding process, avoiding the tilting or shaking caused by the single-point support; the multiple sliders 106 arranged at the bottom of the slide 304 are evenly distributed and spaced to cooperate with the slide bars 105, further constraining the motion trajectory of the slide 304, reducing the cumulative error during the sliding process, and ensuring the accuracy of the positioning of the slide 304.

[0033] More preferably, the transformer coil winding device further comprises a third driving member, which is arranged on the slide 304, the mounting shaft 401 is a tightening shaft, the power output end of the third driving member is connected to the mounting shaft 401, and is used to drive the mounting shaft 401 to tighten or retract, and the third driving member is electrically connected to the control component.
