Description

Technical Field

[0001] This utility model relates to the field of electromagnetic wire diameter detection technology, specifically an electromagnetic wire diameter detection device. Background Technology

[0002] Magnet wire is an insulated wire used to manufacture coils or windings in electrical products. It typically consists of a conductive metal core covered with an insulation layer. After the magnet wire is manufactured, a diameter measuring device is used to check the uniformity of the magnet wire diameter and verify whether the produced wire conforms to the drawings or international standards.

[0003] Chinese patent CN 222761604 U discloses a device for detecting the dimensions of electromagnetic wire production. The device includes a detection platform with a feed roller and a take-up roller rotatably connected to both sides of the platform. The feed roller winds the electromagnetic wire and releases it outwards, while the take-up roller winds it up. A diameter detection mechanism is located in the center of the platform. This invention uses a first motor to rotate the take-up roller to wind the electromagnetic wire, and a second motor to rotate a screw, causing a guide block to move back and forth in a guide groove and synchronously moving the take-up roller. This ensures the electromagnetic wire is evenly wound onto the take-up roller. Each rotation of the take-up roller aligns the magnet with the detection probe once, and this alignment is counted. The length of the electromagnetic wire is equal to the circumference of one rotation around the take-up roller multiplied by the number of times the magnet aligns with the detection probe. Additionally, two clamping blocks are moved to clamp the electromagnetic wire from both sides. At this point, an arrow points to a scale line, and the value on the scale line is read. The diameter of the electromagnetic wire is then calculated.

[0004] In existing detection devices, the electromagnetic wire may vibrate during the detection of the uniformity of the electromagnetic wire diameter, leading to eccentricity errors, reduced dynamic accuracy, and poor stability of the electromagnetic wire, thus affecting the accuracy of the detection. Therefore, an electromagnetic wire diameter detection device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes an electromagnetic wire diameter detection device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an electromagnetic wire diameter detection device, including a base, a support frame mounted on the base, a detection component mounted on the support frame, the detection component including a detection seat, a reference surface provided on the detection seat, an installation groove provided in the detection seat, a laser displacement sensor mounted in the installation groove, a transmitter and a receiver mounted on the laser displacement sensor, a sliding groove provided in the detection seat, a slider assembled in the sliding groove, a sliding frame mounted on the slider, a pressure block mounted on the sliding frame, the pressure block and the reference surface being made of POM material, a fixing block mounted on the detection seat, two springs and a damper mounted on the fixing block, the other ends of the two springs and the damper being fixedly connected to the pressure block, two guide wheels symmetrically mounted on the side wall of the detection seat via a wheel frame, and a first winding assembly mounted on the base, the first winding assembly including a mounting frame, the mounting... The frame is fixedly mounted on the base. A drive motor is mounted on the frame via a base. A take-up roller is mounted on the output shaft of the drive motor. The take-up roller is rotatably mounted on the frame and has a take-up wheel on it. Electromagnetic wire is wound on the take-up wheel. A second take-up assembly is mounted on the base. The second take-up assembly has the same internal structure as the first take-up assembly. Two springs are always in a compressed state. The two springs drive a pressure block to apply pressure to the electromagnetic wire, pressing the electromagnetic wire against the reference surface to ensure that it is always in contact with the reference surface. This can improve the rigidity of the guide pressing. The pressure block and the reference surface are made of POM material, which can reduce the vibration caused by friction between the electromagnetic wire and the reference surface. This structure, through rigid guidance, damping control, and friction reduction, can ensure the movement stability of the electromagnetic wire, avoid the eccentric error caused by electromagnetic wire vibration, and prevent a decrease in dynamic accuracy. This is beneficial to improving the stability of the electromagnetic wire and improving the detection accuracy.

[0007] Preferably, a mounting bracket is installed on the base, and a PLC touch screen is fixedly mounted on the mounting bracket. An alarm light is installed on the detection base, and the alarm light is connected to the PLC touch screen through an internal circuit. The PLC touch screen is connected to two drive motors through an internal circuit. When the detected diameter value is unqualified, the programmable logic controller inside the PLC touch screen controls the alarm light to turn on and controls the first and second winding components to stop operating, so as to prompt the operator and facilitate the operator to mark the unqualified line segment. This structure can quickly mark and identify the unqualified part of the electromagnetic wire, which is beneficial to improving the practicality of the detection.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes two springs that are always compressed. These springs drive a pressure block to apply pressure to the electromagnetic wire, pressing it against a reference surface and ensuring it remains in contact with the surface. This improves the rigidity of the guiding pressure. The pressure block and the reference surface are made of POM material, which reduces vibration caused by friction between the electromagnetic wire and the reference surface. This structure, through rigid guidance, damping control, and friction reduction, ensures the stability of the electromagnetic wire's movement, avoids vibration that could lead to eccentricity errors and decreased dynamic accuracy, and improves the stability of the electromagnetic wire, thus enhancing detection accuracy.

[0010] 2. When the detected diameter value is unqualified, the programmable logic controller inside the PLC touch screen controls the alarm light to turn on and controls the first and second winding components to stop operating, so as to remind the operator and facilitate the operator to mark the unqualified line segment. This structure can quickly mark and identify the unqualified part of the electromagnetic wire, which is beneficial to improving the practicality of the detection. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5As shown, an electromagnetic wire diameter detection device includes a base 1, a support frame 2 mounted on the base 1, and a detection assembly mounted on the support frame 2. The detection assembly includes a detection seat 3, a reference surface 301 on the detection seat 3, an installation groove inside the detection seat 3, a laser displacement sensor 302 mounted in the installation groove, a transmitter 303 and a receiver 304 mounted on the laser displacement sensor 302, a sliding groove 305 on the detection seat 3, a slider 306 assembled in the sliding groove 305, a sliding frame 307 mounted on the slider 306, and a pressure block 308 mounted on the sliding frame 307. The pressure block 308 and the reference surface 301 are made of POM material. A fixing block 309 is mounted on the detection seat 3, and two springs 310 and a damper 311 are mounted on the fixing block 309. The other ends of the two springs 310 and the damper 311 are fixedly connected to the pressure block 308. Two guide wheels 6 are symmetrically mounted on the side wall of the detection seat 3 via wheel frames. A first winding assembly 4 is mounted on the base 1. The winding assembly 4 includes a mounting frame 401, which is fixedly mounted on the base 1. A drive motor 402 is mounted on the mounting frame 401 via a base. A winding roller 403 is mounted on the output shaft of the drive motor 402. The winding roller 403 is rotatably mounted on the mounting frame 401. A winding wheel 404 is mounted on the winding roller 403. Electromagnetic wire 5 is wound on the winding wheel 404. A second winding assembly 7 is mounted on the base 1. The second winding assembly 7 has the same internal structure as the first winding assembly 4. During operation, the existing detection device may cause the electromagnetic wire 5 to vibrate during the detection of the uniformity of the diameter, resulting in eccentricity error and decreased dynamic accuracy. This leads to poor stability of the electromagnetic wire 5 and affects the accuracy of the detection. After the electromagnetic wire 5 is produced, it is necessary to detect the uniformity of the diameter of the electromagnetic wire 5. The wire diameter tolerance must be ≤±1% to verify whether the produced wire conforms to the drawings or international standards. Therefore, a diameter detection device is needed to check the electromagnetic wire 5.

[0020] Before the electromagnetic wire 5 is tested, the electromagnetic wire 5 is loosened by the first winding assembly 4, passes around the first guide wheel 6, then winds around the test seat 3 and is in contact with the reference surface 301, then passes around the second guide wheel 6, and finally is wound up by the second winding assembly 7. At this time, the electromagnetic wire 5 between the first winding assembly 4 and the second winding assembly 7 is in a taut state.

[0021] During the testing process, the first winding assembly 4 operates, and its internal drive motor 402 operates, driving the winding roller 403 to rotate. The winding roller 403 drives the winding wheel 404 to rotate, and the winding wheel 404 loosens the electromagnetic wire 5. Similarly, the second winding assembly 7 operates, and its internal winding wheel 404 winds the electromagnetic wire 5. The programming logic controller in the PLC touch screen 801 controls the two drive motors 402 to run synchronously at the same speed and direction by programming the same pulse output frequency and direction signals. Therefore, the first winding assembly 4 and the second winding assembly 7 operate synchronously, which can keep the electromagnetic wire 5 between the first winding assembly 4 and the second winding assembly 7 always taut.

[0022] During the movement of the electromagnetic wire 5 on the reference surface 301, the electromagnetic wire 5 may vibrate, leading to eccentricity errors. Therefore, it is necessary to limit the movement of the electromagnetic wire 5. The two springs 310 on the fixing block 309 are always compressed. The two springs 310 apply a pushing force to the sliding frame 307, which in turn applies a pushing force to the pressure block 308. The pressure block 308 applies pressure to the electromagnetic wire 5, pressing it against the reference surface 301. This forcibly corrects the eccentricity or positional deviation of the electromagnetic wire 5, ensuring it remains in contact with the reference surface 301, thus improving the rigidity of the guide pressure. The springs 310 are made of fatigue-resistant SWOSC-V alloy steel to prevent a decrease in the elastic modulus after long-term compression, thus reducing pressure. The damper 311, model HY-05, is added to the movement path of the pressure block 308 to absorb high-frequency micro-vibrations. The pressure block 308 and the reference surface 301 are made of POM material. POM is a high-performance engineering plastic with high mechanical strength, wear resistance and self-lubrication, which can reduce the vibration caused by friction between the electromagnetic wire 5 and the reference surface 301. This structure, through rigid guidance, damping control and friction reduction, can ensure the movement stability of the electromagnetic wire 5, avoid the eccentricity error caused by the vibration of the electromagnetic wire 5, and reduce the dynamic accuracy. This is beneficial to improving the stability of the electromagnetic wire 5 and improving the detection accuracy.

[0023] Please see Figure 1 As shown, a mounting bracket 8 is installed on the base 1, and a PLC touch screen 801 is fixedly installed on the mounting bracket 8. An alarm light 802 is installed on the detection base 3. The alarm light 802 is connected to the PLC touch screen 801 through an internal circuit. The PLC touch screen 801 is connected to two drive motors 402 through an internal circuit. During operation, the existing detection device has difficulty in quickly identifying the non-conforming parts of the electromagnetic wire 5 when detecting the uniformity of the diameter of the electromagnetic wire 5, resulting in poor practicality of the detection. The PLC touch screen 801 is a device that combines the control function of a programmable logic controller with a human-machine interface. It contains a programmable logic controller and a display screen, which can display key information such as the operating status of the equipment and measurement data in real time.

[0024] During the process of detecting the diameter of the electromagnetic wire 5, as the electromagnetic wire 5 moves on the reference surface 301, the pressure block 308 presses the electromagnetic wire 5 and keeps it in contact with the reference surface 301. Therefore, the distance between the pressure block 308 and the reference surface 301 is the diameter value of the electromagnetic wire 5.

[0025] The laser displacement sensor 302, model TS-P150, measures the distance between itself and the pressure block 308. The working principle of the laser displacement sensor 302 is as follows: the transmitter 303 generates a laser beam that illuminates the pressure block 308. After the laser beam illuminates the pressure block 308, it is reflected by the pressure block 308 to the receiver 304. The receiver 304 receives the reflected beam, converts it into an electrical signal, and transmits it to the PLC touchscreen 801. The signal processing system inside the PLC touchscreen 801 calculates the distance between the pressure block 308 and the laser displacement sensor 302 based on the received electrical signal. The final distance value can be directly displayed on the screen of the PLC touchscreen 801.

[0026] Before measuring the electromagnetic wire 5, the pressure block 308 is initially in contact with the reference surface 301. At this time, the laser displacement sensor 302 measures the distance between itself and the pressure block 308 as the initial value. During the measurement of the electromagnetic wire 5, the measured distance value minus the initial value is the diameter value of the electromagnetic wire 5. The acceptable diameter of the electromagnetic wire 5 is that the wire diameter tolerance must be ≤±1%. When the detected diameter value is unacceptable, the programmable logic controller inside the PLC touch screen 801 controls the alarm light 802 to turn on and controls the first winding assembly 4 and the second winding assembly 7 to stop operating, so as to prompt the operator and facilitate the operator to mark the unacceptable wire segment. This structure can quickly mark and identify the unacceptable part of the electromagnetic wire 5, which is beneficial to improving the practicality of the detection.

[0027] Working principle: In the process of detecting the uniformity of the diameter of the electromagnetic wire 5 using existing detection devices, the electromagnetic wire 5 may vibrate, leading to eccentricity errors and decreased dynamic accuracy. This results in poor stability of the electromagnetic wire 5, affecting the accuracy of the detection. After the electromagnetic wire 5 is produced, it is necessary to detect the uniformity of its diameter, with a diameter tolerance of ≤±1%, to verify whether the produced wire conforms to the drawings or international standards. Therefore, a diameter detection device is needed to inspect the electromagnetic wire 5. Before the electromagnetic wire 5 is detected, it is loosened by the first winding assembly 4, passes around the first guide wheel 6, then winds onto the detection seat 3 and is in contact with the reference surface 301, then passes around the second guide wheel 6, and finally is wound by the second winding assembly 7. During winding, the electromagnetic wire 5 between the first winding assembly 4 and the second winding assembly 7 is taut. During the detection process, the first winding assembly 4 operates, causing its internal drive motor 402 to rotate, which in turn rotates the winding roller 403. The winding roller 403 then rotates the winding wheel 404, which releases the electromagnetic wire 5. Similarly, the second winding assembly 7 operates, and its winding wheel 404 winds the electromagnetic wire 5. The programmable logic controller (PLC) in the PLC touchscreen 801 controls the two drive motors 402 to operate synchronously at the same speed and direction by programming the same pulse output frequency and direction signals. Therefore, the first winding assembly 4 and the second winding assembly 7 operate synchronously, allowing the first winding assembly 4 and the second winding assembly 7 to operate synchronously. The electromagnetic wire 5 between components 7 is always kept taut. During its movement on the reference surface 301, the electromagnetic wire 5 may vibrate, leading to eccentricity errors; therefore, it needs to be limited. The two springs 310 on the fixing block 309 are always compressed. These springs apply a pushing force to the sliding frame 307, which in turn applies a pushing force to the pressure block 308. The pressure block 308 then applies pressure to the electromagnetic wire 5, pressing it against the reference surface 301. This forcibly corrects the eccentricity or positional deviation of the electromagnetic wire 5, ensuring it remains in contact with the reference surface 301, thus improving the rigidity of the guide press. The springs 310 are made of fatigue-resistant SWOSC-V alloy steel to prevent them from springing back after long-term compression. The modulus of elasticity decreases, resulting in insufficient pressure. A damper 311 (model HY-05) is added to the movement path of the pressure block 308 to absorb high-frequency micro-vibrations. The pressure block 308 and the reference surface 301 are made of POM, a high-performance engineering plastic with high mechanical strength, wear resistance, and self-lubricating properties. This reduces vibrations caused by friction between the electromagnetic wire 5 and the reference surface 301. This structure, through rigid guidance, damping control, and friction reduction, ensures the stability of the electromagnetic wire 5's movement, preventing vibrations that could lead to eccentricity errors and decreased dynamic accuracy. This improves the stability of the electromagnetic wire 5 and enhances detection accuracy.Existing testing devices struggle to quickly identify defects in the diameter of the electromagnetic wire 5 during the inspection of its uniformity, resulting in poor practicality. The PLC touchscreen 801, a device combining programmable logic controller (PLC) control functions with a human-machine interface, integrates a PLC and a display screen to show real-time equipment operating status, measurement data, and other key information. During the inspection of the electromagnetic wire 5's diameter, as the electromagnetic wire 5 moves on the reference surface 301, the pressure block 308 keeps it in constant contact with the reference surface 301. Therefore, the distance between the pressure block 308 and the reference surface 301 represents the diameter of the electromagnetic wire 5. The laser displacement sensor 302 (model TS-P150) measures the distance between itself and the pressure block 308. The laser displacement sensor 302 works by having an emitter 303 generate a laser beam that illuminates the pressure block 308. The laser beam is then reflected by the pressure block 308 to a receiver 304, which receives the reflected beam and converts it into a digital image. The signal is converted into an electrical signal and transmitted to the PLC touchscreen 801. The signal processing system inside the PLC touchscreen 801 calculates the distance between the pressure block 308 and the laser displacement sensor 302 based on the received electrical signal. The final distance value can be directly displayed on the screen of the PLC touchscreen 801. Before measuring the electromagnetic wire 5, the pressure block 308 is initially in contact with the reference surface 301. At this time, the laser displacement sensor 302 measures the initial distance between itself and the pressure block 308. During the measurement of the electromagnetic wire 5, the measured distance value minus the initial value is the diameter value of the electromagnetic wire 5. The acceptable diameter of the electromagnetic wire 5 is that the wire diameter tolerance must be ≤±1%. When the detected diameter value is unacceptable, the programmable logic controller inside the PLC touchscreen 801 controls the alarm light 802 to turn on and controls the first winding assembly 4 and the second winding assembly 7 to stop operating, so as to prompt the operator and facilitate the operator to mark the unacceptable wire segment. This structure can quickly mark and identify the unacceptable part of the electromagnetic wire 5, which is beneficial to improving the practicality of the detection.
