Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of enameled wire processing, in particular to an enameled wire defect monitoring device. BACKGROUND

[0002] Enameled wire is a main variety of winding wire, which is composed of a conductor and an insulating layer. After the bare wire is annealed and softened, it is coated and baked multiple times to form an enameled wire. In order to ensure the high quality of the production and processing of flat enameled wire, the surface of the flat enameled wire needs to be monitored and detected for defects.

[0003] The existing technology faces multiple technical bottlenecks: first, the traditional coating process is difficult to adapt to the corner structure of the flat conductor, resulting in a coating thickness deviation of more than ± 20 μm, especially when multiple coatings are applied, local coating omission is prone to occur; second, during the drying process, due to uneven airflow temperature and the lack of controllable pressure, air bubbles often occur inside the coating; third, defect detection relies on manual visual inspection or single electromagnetic induction detection, and the recognition rate of defects such as cracks less than 0.1 mm and uneven thickness is low, and real-time linkage repair mechanisms cannot be realized; the core defect of the existing technology is the lack of sensor application singularity and linkage: most devices only use electromagnetic sensors to detect conductor defects, and lack visual recognition of the surface topography of the coating; the pressing mechanism is not equipped with a mechanical sensor, resulting in uncontrolled pressing force, which is easy to damage the enameled wire; the drying link lacks temperature sensor closed-loop control, and the airflow temperature fluctuates greatly, affecting the coating curing effect.

[0037] Specifically, the second fixed rotating shaft 15 is rotated by the motor 14, which drives the upper group of straight gears 71 to rotate. The straight gears 71 drive the external tooth ring 73 to rotate, which drives the lower group of straight gears 71 to rotate. The two groups of straight gears 71 limit the position of the external tooth ring 73 through the baffles 72. The external tooth ring 73 drives the paint spraying heads 79 to spray the enameled wire body 12. The spraying range of the paint spraying heads 79 is limited by the circular ring plate 710, so that the enameled wire body 12 can be fully covered by the coating.

[0041] Specifically, the fixed block 91 is used for mounting the fixed rod 92, the limiting block 93 ensures the sliding range of the first sliding block 95, the eccentric sleeve 98 is driven by the second fixed rotating shaft 15, and the eccentric sleeve 98 drives the roller 97 by eccentric design to make the roller 97 drive the first sliding block 95 to slide on the outer side of the fixed rod 92.

[0042] In the embodiment, one side of the first sliding block 95 is fixedly connected with a sliding rod 94, an outer side of the sliding rod 94 is slidingly connected with the fixed block 91, the outer side of the sliding rod 94 is provided with a second spring 96, one end of the second spring 96 is fixedly connected with the sliding rod 94, the other end of the second spring 96 is fixedly connected with the fixed block 91, and one end of the sliding rod 94 is fixedly connected with an L-shaped connecting rod 99.

[0043] Specifically, the first sliding block 95 drives the sliding rod 94 to slide horizontally on the inner side of the fixed block 91, and the second spring 96 is compressed during sliding, the limiting block 93 avoids the first sliding block 95 from being separated from the fixed rod 92 when the second spring 96 returns, and the sliding rod 94 drives the L-shaped connecting rod 99 to move when sliding.

[0044] In the embodiment, an outer side of the L-shaped connecting rod 99 is fixedly connected with a second sliding block 910, an outer side of the second sliding block 910 is provided with a sliding groove 911, inner sides of the sliding groove 911 are fixedly connected with two groups of symmetrical polishing pieces 912, and inner sides of the sliding groove 911 are provided with tactile sensors.

[0045] Specifically, the L-shaped connecting rod 99 drives the second sliding block 910 to move, the enameled wire body 12 passes through the sliding groove 911, the second sliding block 910 drives the polishing pieces 912 to move back and forth when moving back and forth, so that protruding points are avoided on the outer side of the enameled wire body 12 by back and forth friction, the smoothness of the outer side of the enameled wire body 12 is maintained, the tactile sensors perceive the change of polishing resistance, and the defect position is fed back in real time.

[0046] In this embodiment, the rear end of the lower second fixed rotating shaft 15 is fixedly connected with the third fixed rotating shaft 16, the outer side of the third fixed rotating shaft 16 is fixedly connected with the cross-shaped sweeping rod 17, and the inner side of the first processing bin 5 is provided with the discharge groove 18. The lower end of the discharge groove 18 is provided with the collecting box 11.

[0047] Specifically, the lower second fixed rotating shaft 15 drives the third fixed rotating shaft 16 to rotate, and the third fixed rotating shaft 16 drives the cross-shaped sweeping rod 17 to sweep, so that the upper debris is concentrated to the collecting box 11.

[0048] The working principle is that, in use, the enameled wire body 12 is inserted into the first processing bin 5 through the workbench 1, and the position is detected by the two groups of symmetrical distance sensors 19. When the enameled wire body 12 triggers the distance sensor 19, the signal is transmitted to the motor 14, and the output shaft of the motor 14 drives the upper second fixed rotating shaft 15 to rotate. The second fixed rotating shaft 15 is engaged with the external tooth ring 73 through the straight gear 71, so that the external tooth ring 73 drives the four groups of paint spraying heads 79 to rotate around the enameled wire body 12 by 360°, the circular ring plate 710 limits the spraying range to avoid missing the coating, and the clamping block 74 at the rear end of the external tooth ring 73 drives the third connecting rod 76 to rotate through the first fixed rotating shaft 75, so that the rubber ring 77 is synchronously attached to the surface of the enameled wire body 12. The inner side of the rubber ring 77 is matched with the inclined surface design of the front and rear guide rings 78, and according to the flat characteristics of the enameled wire, the coating is uniformly and smoothly wiped.

[0049] When the enameled wire body 12 enters the second processing bin 2, the second fixed rotating shaft 15 drives the eccentric rotating block 41 to rotate, and intermittently presses the second connecting rod 47. The second connecting rod 47 pushes the pressing rod 44 in the first sliding groove 43 of the fixed support 42 through the first connecting rod 46, compresses the first spring 45, and drives the installation box 48 to make the C-shaped pressing plate 49 press downward. At this time, the pressure sensor on the inner side of the pressing rod 44 monitors the pressing degree in real time, so as to ensure that a constant pressure of 20-30N is applied, and to avoid coating bubbles or enameled wire damage;

[0050] When the two groups of C-shaped pressing plates 49 are attached, the electrical sensor and the magnetic sensor on the inner side thereof work synchronously: the electrical sensor detects that the coating insulation resistance standard value is greater than or equal to 10MΩ, and the magnetic sensor monitors that the conductor magnetic field uniformity deviation is less than or equal to ±5%. If the detection value is abnormal, the system automatically marks the defect position. At the same time, the exhaust fan 411 is started, the heating block 415 is heated to 60-80℃, and the airflow is output from the first exhaust pipe 412 to the second exhaust pipe 413, so as to quickly dry the coating. When the C-shaped pressing plate 49 is attached, the airflow is output from the third exhaust pipe 414 to the third processing bin 8, so as to clean the enameled wire surface debris; when the pressing plate is reset, the second exhaust pipe 413 continues to dry, and an alternating drying process is formed.

[0051] The harmful gas and dust in the first processing chamber 5 are sucked into the activated carbon adsorption box 410 through the L-shaped suction pipe 417 by the suction fan 416, and the suction pipe 417 slides in the third sliding groove 21 to adapt to the pressing plate action;

[0052] After the enameled wire body 12 enters the third processing chamber 8, the second fixed rotating shaft 15 above drives the eccentric sleeve 98 to rotate, and the eccentric design pushes the roller 97 to make the first sliding block 95 slide horizontally on the fixed rod 92. The first sliding block 95 drives the L-shaped connecting rod 99 through the sliding rod 94, so that the polishing piece 912 in the sliding groove 911 of the second sliding block 910 rubs the surface of the enameled wire back and forth. The tactile sensor on the inner side of the sliding groove 911 senses the polishing resistance in real time, and when the resistance suddenly changes by more than 15% of the reference value, it is determined that there is a protruding defect;

[0053] At the same time, the two groups of CCD cameras on the inner wall of the third processing chamber 8 visually scan the surface of the enameled wire, detect defects such as cracks and uneven thickness with a resolution of 0.05mm through image recognition algorithms, and cross-verify with the tactile sensor data. After confirming the defect, the polishing piece 912 is ground in a targeted manner, the third exhaust pipe 414 outputs airflow to clean the polishing debris, and the second fixed rotating shaft 15 below drives the cross-shaped sweeping rod 17 to rotate through the third fixed rotating shaft 16, so that the debris is swept into the collection box 11 through the discharge groove 18. The second sliding groove 20 and the third sliding groove 21 respectively provide sliding space for the third exhaust pipe 414 and the suction pipe 417, ensuring that the airflow path is not disturbed by the mechanism action.

[0054] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
