Abstract
Description
Technical Field
[0001] This utility model relates to the field of enameled wire testing technology, and in particular to a testing device for enameled wire after it has been manufactured. Background Technology
[0002] Enameled wire, as a key basic material in electronics, electrical engineering, and other fields, directly affects the performance and safety of end products. After production, enameled wire must undergo rigorous testing before it can be wound up and released to the market. Among the many testing items, the bending resistance and tensile strength of enameled wire play a decisive role in evaluating product quality and ensuring its reliability in real-world applications.
[0003] However, traditional testing primarily relies on manual operation of a single testing device to assess the bending and tensile properties of enameled wire. This method is not only inefficient but also has extremely limited coverage. Because manual inspection makes it difficult to meticulously examine every section of enameled wire, omissions are common, making it impossible to ensure that all enameled wire meets standards. Furthermore, manual operation is susceptible to subjective biases; different inspectors use varying techniques and have different judgment criteria, leading to inconsistent and inaccurate test results. In addition, traditional testing equipment is limited in function and cannot perform multi-dimensional, one-stop testing, further reducing efficiency and increasing costs, making it difficult to meet the quality testing requirements of modern large-scale industrial production.

[0028] Reference Figure 1-6 A testing device for enameled wire after forming, comprising a testing table 1, and further comprising:
[0029] The guide component 2 is set on the surface of the inspection table 1 and is used to guide and clamp the enameled wire so that the enameled wire remains taut during movement.
[0030] The first detection component 3, mounted on the surface of the detection table 1, is used for bending detection of the enameled wire. The first detection component 3 includes a slide bar 32, with a pulley 33 and a high-speed camera 34 on its surface. A second electric rod 31 is fixedly mounted on the surface of the detection table 1. The slide bar 32 is slidably connected to the surface of the detection table 1, and the output end of the second electric rod 31 is fixedly connected to the slide bar 32. The surface of the pulley 33 is made of highly wear-resistant rubber to increase friction with the enameled wire, preventing slippage during bending and protecting the wire surface from scratches. The second electric rod 31 is an electric push rod, and a high-precision displacement sensor is mounted on its side to monitor the movement distance of the slide bar 32 in real time, thereby precisely controlling the degree of bending of the enameled wire. The "L"-shaped structure of the slide bar 32 is made of high-strength aluminum alloy and precision-machined to ensure dimensional accuracy and structural strength. The axle of the pulley 33 is rotatably connected to the vertical section of the slide bar 32 via a deep groove ball bearing, allowing the pulley 33 to rotate smoothly when in contact with the enameled wire. The surface of pulley 33 is made of high-wear-resistant rubber material with a rubber layer thickness of 5 mm. This rubber material not only has good wear resistance but also a certain degree of flexibility. It can increase the friction between the pulley and the enameled wire, preventing slippage during the bending process, and effectively protect the surface of the enameled wire from scratches. The high-speed camera 34 uses an industrial-grade high-definition camera with a frame rate of up to 200 frames per second and a resolution of 2048×1536 pixels. It can clearly capture the bending of the enameled wire at the contact point between pulley 33 and the enameled wire, recording the entire bending process. When the first detection component 3 is activated, the control unit sends a command to the second electric rod 31. The output end of the second electric rod 31 drives the slide bar 32 to move up on the surface of the detection table 1. The pulley 33 on the vertical section of the slide bar 32 contacts the enameled wire and bends it. The high-speed camera 34 simultaneously records whether there are cracks or other phenomena on the surface of the enameled wire at the bending point, realizing the bending detection of the enameled wire.
[0031] The second detection component 4 is located below the first detection component 3 and is used to perform tensile testing on the enameled wire.
[0032] The winding assembly 5 is set on the surface of the inspection table 1 and is used to wind and store the enameled wire after inspection.
[0033] After the enameled wire enters the testing device, the guide assembly 2 first guides and clamps the wire, keeping it taut. The first testing assembly 3 is activated, and the second electric rod 31 moves the slide bar 32 up the surface of the testing table 1. The pulley 33 on the slide bar 32 contacts the wire, causing it to bend. The high-speed camera 34 records whether there are cracks or other phenomena on the surface of the bent wire, thus achieving bending detection. The second testing assembly 4 is used intermittently as needed. When the second testing assembly 4 is in use, the slide bar 32 moves downwards. At this time, the wire is wound up and taut, positioned directly on the second testing assembly 4. The winding assembly 5 pauses operation, and the second testing assembly 4 is used to perform tensile testing on the wire. During the stretching process, the high-speed camera 34 continues to monitor the stretched section of the wire, evaluating its tensile performance. After the test is completed, the winding assembly 5 winds up the tested wire for easy subsequent processing. It integrates guiding, bending detection, tensile strength detection and winding functions, realizing one-stop inspection after the enameled wire is produced and formed, improving inspection efficiency, ensuring the accuracy of inspection results, and providing reliable support for the quality control of enameled wire.
[0034] Furthermore, the guide assembly 2 includes a mounting plate 21, which is fixedly connected to the detection table 1. A first guide wheel 22 is rotatably connected near the bottom of the mounting plate 21. A slider 24 is slidably connected to the surface of the mounting plate 21. A second guide wheel 23 is rotatably connected to the surface of the slider 24. A first electric rod 25 is fixedly mounted on the top of the mounting plate 21. The output end of the first electric rod 25 is fixedly connected to the slider 24. An enameled wire passes between the first guide wheel 22 and the second guide wheel 23.
[0035] When it is necessary to adjust the clamping force on the enameled wire, the first electric lever 25 is activated, and its output end pushes the slider 24 to slide on the surface of the mounting plate 21, changing the position of the second guide wheel 23, thereby adjusting the clamping force of the first guide wheel 22 and the second guide wheel 23 on the enameled wire. This can adapt to the testing requirements of enameled wires of different specifications, ensuring that the enameled wire remains in a stable and taut state during the testing process, and improving the accuracy and stability of the testing.
[0036] Furthermore, the slide bar 32 has an "L" shaped structure, the high-speed camera 34 is installed on the top horizontal section of the slide bar 32, and the pulley 33 is rotatably connected to the vertical section of the slide bar 32, with the pulley 33 located directly below the high-speed camera 34.
[0037] Under the push of the second electric rod 31, the vertical section of the "L"-shaped slide bar 32, with its pulley 33, contacts the enameled wire and bends it. Since the high-speed camera 34 is installed on the top horizontal section of the slide bar 32, and the pulley 33 is located directly below the high-speed camera 34, the high-speed camera 34 can clearly capture the bending of the enameled wire at the contact point between the pulley 33 and the enameled wire, recording the entire bending process.
[0038] Furthermore, the second detection component 4 includes a fixing plate 41, which is fixedly connected to the detection table 1. The surface of the fixing plate 41 is provided with two connecting blocks 43. Each connecting block 43 has a clamping component on its surface, comprising two clamping blocks 44. Both clamping blocks 44 are slidably connected to the connecting blocks 43. A lead screw 47 rotatably passes through the surface of the connecting blocks 43. The lead screw 47 has opposite threads at both ends, with its midpoint as the boundary. The two clamping blocks 44 are threadedly connected to both ends of the lead screw 47. A first motor 46 is fixedly installed at the end of the connecting block 43. The output shaft port of motor 6 is fixedly connected to the lead screw 47. Rubber pads 45 are fixedly installed on opposite sides of the two clamping blocks 44. A sliding groove 48 is formed on the surface of the fixing plate 41. One connecting block 43 is fixed to the fixing plate 41, and the other connecting block 43 is slidably connected to the sliding groove 48. A third electric rod 42 is fixedly installed within the sliding groove 48. The output end of the third electric rod 42 is fixedly connected to the movable connecting block 43. The first motor 46 is an ECMA-C20604 servo motor with a rated torque of 4 N·m and a speed range of 0-3000 rpm. Equipped with an absolute encoder with a resolution of 2500 lines, it can precisely control the rotation angle of the lead screw 47, achieving accurate positioning of the clamping blocks 44.
[0039] After the slide bar 32 moves down, the enameled wire falls above the second detection component 4. At this time, the winding component 5 first winds up the slack section of the enameled wire, and then the enameled wire falls between the clamping blocks 44 of the two connecting blocks 43. The first motor 46 drives the lead screw 47 to rotate. Since the lead screw 47 has opposite threads at both ends with the midpoint as the boundary, the two clamping blocks 44 will move closer or further apart, thereby clamping or releasing the enameled wire. The rubber pad 45 increases the friction between the clamping blocks 44 and the enameled wire, preventing the enameled wire from slipping during the detection process. When performing tensile testing, the third electric rod 42 is activated, pushing the movable connecting block 43 to slide in the slide groove 48. The distance between the two connecting blocks 43 increases, stretching the enameled wire. During the stretching process, the camera monitors the changes on the surface of the enameled wire in real time, thereby detecting the tensile performance of the enameled wire.
[0040] Furthermore, the winding assembly 5 includes a second motor 55, which is fixedly mounted on the side wall of the inspection table 1. The output shaft of the second motor 55 is fixedly mounted on a mounting shaft 54, which rotatably passes through the inspection table 1. A baffle 53 is fixedly mounted on the surface of the mounting shaft 54, and a winding wheel 52 is sleeved on its surface. A nut 51 is threadedly connected near the end of the mounting shaft 54. The second motor 55 is a YE2-100L-4 model with a power of 2.2kW and a speed of 1420rpm. Vibration damping pads are installed on the side wall of the inspection table 1. These pads are made of nitrile rubber with a Shore A hardness of 60A, effectively absorbing vibrations generated during motor operation and preventing interference with other components of the inspection device.
[0041] The second motor 55 is started, and its output shaft drives the mounting shaft 54 to rotate. The winding wheel 52 on the mounting shaft 54 rotates accordingly to wind up the tested enameled wire. The nut 51 and the baffle 53 cooperate to fix the winding wheel 52 between them.
[0042] Furthermore, the testing table 1 is also equipped with a control unit, which is electrically connected to the first electric rod 25, the second electric rod 31, the third electric rod 42 and the second motor 55 respectively. It can preset the operating parameters of each driving component and automatically adjust the clamping force of the guide component 2, the detection stroke of the first detection component 3, the tensile force of the second detection component 4 and the winding speed of the winding component 5 according to the specifications of the enameled wire.
[0043] The control unit presets the operating parameters of the first electric rod 25, the second electric rod 31, the third electric rod 42, and the second motor 55. When inspecting enameled wires of different specifications, the operator inputs the specifications of the enameled wires, and the control unit automatically adjusts the clamping force of the guide component 2, the detection stroke of the first detection component 3, the tensile force of the second detection component 4, and the winding speed of the winding component 5 according to the preset program, thereby realizing the automatic adjustment of the inspection process.
[0044] The device also includes a data storage and analysis unit. The bending images of the enameled wire captured by the high-speed camera 33, and the tensile data detected by the second detection component 4, are both transmitted to the data storage and analysis unit. This unit categorizes and stores the data, analyzes it using a preset algorithm, and generates a test report. The test report includes evaluation results of the bending and tensile properties of the enameled wire. It also supports data export for subsequent traceability and research.
