[0053] Preferred embodiment: a tangent method for an inductor coil end cutting device; the device is implemented by installing a skeleton 19 on a winding device 16, and the limiting plate 17 is fitted to the other side of the skeleton 19 through the work of the cylinder 2 18, the cylinder 2 18 compresses and fixes the position of the skeleton 19, the electric push rod 28 contracts, the wire-releasing box 3 moves downward at a uniform speed horizontally to release the wire, and the winding device 16 rotates to cooperate with the wire-releasing box 3 to perform winding work, and the motor 2 12 is operated at the same time, and a trial cutting is performed after the coil winding is completed. The motor 2 12 will drive the threaded tube 29 to rotate while running, and the threaded tube 29 will drive the threaded rod 13 to slide in the trial cutting hole of the fixed block 15 while rotating, and the threaded rod 13 will drive the cutter head 14 to move while sliding, and at this time the cutter head 14 will fit with the inductor 5, and the cutter head 14 will continue to move for trial cutting. After the trial cutting is successful, the electric telescopic rod 2 11 descends and the motor 2 12 runs again to complete the tangent work.

[0054] The specific implementation plan is as follows:

[0055] Step S101, the control system receives the detection data transmitted by the tension sensor, the position sensor and the speed sensor. The control system is preset with a judgment program for the detection data to judge whether the detection data is abnormal to obtain a judgment result. The control system presents the detection data and the corresponding judgment result in the form of numbers or graphics on the control panel 30. In response to the judgment result being normal, the inductor wire 5 is tested for cutting; wherein the tangent speed of the cutter head 14 is set according to the thickness of the inductor wire 5;

[0056] Specifically, when the tension value is less than the first tension threshold, in order to prevent the inductor wires 5 from deforming due to stress, causing uneven winding and affecting the overall winding quality control, the speed of the internal motor of the winding device 16 is adaptively increased so that the tension data is within the first threshold range;

[0057] When the tension value is greater than the first tension threshold, in order to prevent the inductor 5 from being stretched and deformed, or even breaking, which will seriously affect the physical properties and service life of the material, the rotation speed of the internal motor of the winding device 16 is adaptively reduced so that the tension data is within the first threshold range. The tension sensor is used to monitor the tension changes of the coil during the winding process, so that the tension value is controlled within the first threshold range to ensure the tightness and uniformity of the winding.

[0058] Specifically, when the actual fluctuation threshold exceeds the preset fluctuation threshold during winding, the winding accuracy of the inductor 5 is abnormal, and the winding device 16 stops working. The position sensor is used to detect the specific position of the coil on the winding device 16 to ensure the accuracy and consistency of winding;

[0059] If the actual fluctuation threshold is shorter than the preset fluctuation threshold frequency, it may be that the electric push rod 28 pushes too slowly, causing the winding device 16 to be entangled during the winding process. At this time, the winding device 16 stops working, and the control system controls the pushing speed of the electric push rod 28 to be proportional to the internal motor speed of the winding device 16. The control system also records the time when the actual fluctuation threshold of the position sensor exceeds the preset fluctuation threshold. When the speed is adjusted to be consistent, the control system controls the winding device 16 to drive the pay-off drum 26 to rotate in the opposite direction through the internal motor until it is restored to the winding time that does not exceed the preset fluctuation threshold. At this time, the inductor 5 is located on the winding device 16 with winding accuracy and consistency. The control system controls the winding device 16 to drive the pay-off drum 26 to rotate forward through the internal motor, and the position sensor records the current actual fluctuation threshold again. If the actual fluctuation threshold does not become shorter than the preset fluctuation threshold frequency, the winding device 16 continues to operate and performs subsequent trial cutting and cutting work. If the actual fluctuation threshold becomes shorter than the preset fluctuation threshold frequency on the same skeleton 19 again, the winding device 16 stops working and notifies the staff to carry out maintenance.

[0060] If the actual fluctuation threshold is longer than the preset fluctuation threshold frequency, it means that the inductor wire 5 may have a large gap when winding. It may be that the electric push rod 28 pushes too fast, causing a gap in the winding device 16 during the winding process. At this time, the winding device 16 stops working, and the control system controls the pushing speed of the electric push rod 28 to be proportional to the internal motor speed of the winding device 16. The control system also records the time when the actual fluctuation threshold of the position sensor exceeds the preset fluctuation threshold. When the speed is adjusted to be consistent, the control system controls the winding device 16 to drive the pay-off drum 26 to rotate in the opposite direction through the internal motor until The time is restored to not exceeding the preset fluctuation threshold. At this time, the inductor wire 5 is located on the winding device 16 with winding accuracy and consistency. The control system controls the winding device 16 to drive the pay-off reel 26 to rotate forward through the internal motor. The position sensor records the current actual fluctuation threshold again. If the actual fluctuation threshold is not longer than the preset fluctuation threshold frequency, the winding device 16 continues to operate and performs subsequent trial cutting and wire cutting. If the actual fluctuation threshold is longer than the preset fluctuation threshold frequency on the same skeleton 19 again, the winding device 16 stops working and notifies the staff to carry out maintenance.

[0061] Specifically, when winding at high speed, as the winding speed increases, the response speed of the tension sensor increases accordingly to prevent unstable tension from causing wire breakage, loosening or forming a poor coil structure; when high-speed winding is not required, the control system adjusts to reduce the speed of the motor and adjusts to low-speed winding, thereby reducing energy consumption and reducing operating costs. When the actual winding fluctuation threshold exceeds the winding speed of the preset fluctuation threshold, the speed sensor can trigger a protection mechanism to stop the operation of the winding device 16. The speed sensor is used to monitor the coil winding speed to ensure the winding process.

[0062] If no abnormality is detected, the winding device 16 stops running after the winding is completed, and the electric telescopic rod 18 is retracted inward to clamp the inductor 5 with the claw 19, and the coil diameter of the inductor 5 is detected by the rangefinder on the claw 19. If the coil diameter is less than or equal to the set diameter, the motor 2 12 operates normally to keep the tangent speed unchanged. If the coil diameter is greater than the set diameter, the motor 2 12 reduces the speed through the motor controller to reduce the sliding speed of the threaded rod 13 to prevent the cutter head 14 from being damaged due to the fast cutting speed. The electric telescopic rod 3 24 is retracted inward to clamp the claw 2 23 with the inductor 5, and the lifting rod 22 straightens the inductor 5 upward through the linear drive to make the inductor 5 in a taut state, so that the inductor 5 and the cutter head 14 are vertical when tangent. The cut end face of the wire is a plane. The motor 12 is lifted by the extension of the electric telescopic rod 11 so that the position of the threaded rod 13 is parallel to the position of the trial cutting hole. The motor 12 drives the threaded tube 29 to rotate while running. The threaded tube 29 drives the threaded rod 13 to extend and push the knife seat 20 and the knife head 14 to test cut the inductor wire 5 at the adjusted speed. After the test cutting is completed, the image of the end face of the inductor wire 5 is captured by the optical imaging system, and the grayscale distribution and edge features of the image are analyzed by the image processing software and fed back to the control panel 30, so as to evaluate the flatness of the end face. If the grayscale part has uniform color, it is judged that the end face of the wire head is flat. If the grayscale part has different colors, it is judged that the end face of the wire head is uneven.

[0063] Step S102: If the end surface of the wire head is not flat, the winding device 16 stops running, and the control panel 30 obtains the motor speed data within a predetermined time before the machine stops running through the signal transmitted by the motor controller, and determines whether the uniformity of the motor speed data meets the first preset condition (the first preset condition is that the average number of revolutions per second of the motor speed within 30 seconds is within the range of D (revolutions)). If not, the control system adjusts the voltage of the internal motor through the motor controller to control the stability of the voltage.

[0064] If the condition is satisfied, an alarm is issued to prompt the user to replace the cutter head 14. If the end surface of the test cut is still uneven after the cutter head 14 is replaced, it may be that the lifting rod 22 fails to completely straighten the inductor line 5. The linear drive is controlled to lift the lifting rod 22 to adjust the distance between the second clamping claw 23 and the first clamping claw 9, so that the inductor line 5 is in a straightened state until the end surface of the test cut is flat.

[0065] If the end surface of the trial cutting head is flat, after adjusting the threaded rod 13 to retract to the fixed block 15, the motor 2 12 is lowered by retracting the electric telescopic rod 2 11 so that the position of the threaded rod 13 is parallel to the position of the tangent hole. The motor 2 12 will drive the threaded tube 29 to rotate while running. The threaded tube 29 will drive the threaded rod 13 to slide to the left in the trial cutting hole of the fixed block 15 while rotating. The threaded rod 13 will drive the cutter head 14 to move to the left while sliding to the left to perform a tangent operation on the inductor 5. By controlling the flatness of the end surface of the inductor coil, the electromagnetic properties of the coil, including inductance and reactance, etc., affected by uneven current distribution inside the coil can be avoided.
