Description

Technical Field

[0001] This utility model relates to the field of defect detection technology, and in particular to a device for detecting surface defects in tin-plated copper wire. Background Technology

[0002] Tinned copper wire is a conductive wire made of copper wire as the base material, with a thin layer of tin coated on its surface by electroplating or hot-dip immersion. Surface defect detection of tinned copper wire is mainly to ensure its quality and performance.

[0003] Patent CN219675855U discloses a cable surface defect detection device. The device includes a detection box with a detection channel for cables to pass through, and detection components housed within the box. When using this patent, the cable is transported through a roller assembly, and the detection components' CCD camera performs the inspection. However, this existing patent has some shortcomings in practical use. Because there is no fixed mechanism between the two pairs of rollers in the existing patent, uneven cable tension can occur during inspection, leading to cable breakage and affecting the inspection results.

[0004] Therefore, there is a need to provide a surface defect detection device for tin-plated copper wire with a limiting and fixing function. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patent's two pairs of rollers without a fixed position, which can lead to uneven tension of the wire during testing, resulting in wire breakage and affecting the test results, this utility model provides a tin-plated copper wire surface defect detection device with a fixed position function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: A surface defect detection device for tin-plated copper wire, comprising a support base, a control box, a detection box, a mounting base, a guide wheel, a controller, an industrial display screen, and a detection mechanism. The control box is fixedly connected to the support base, and the detection box is fixedly connected to the upper part of the support base. Four mounting bases are fixedly connected to the detection box, and guide wheels are rotatably mounted on the mounting bases. The controller is mounted on the detection box, and the industrial display screen is mounted on the controller. The controller and the industrial display screen are electrically connected. The detection mechanism for detection is located inside the detection box, and also includes a fixed base, guide rods, a connecting plate, elastic elements, threaded rods, and arc-shaped clamping plates. Multiple fixed bases are fixedly connected to the detection box, and threaded rods are rotatably mounted on the fixed bases. Arc-shaped clamping plates are threaded onto the threaded rods. Two guide rods are slidably mounted on the fixed bases. A connecting plate is fixedly connected between the two guide rods and the threaded rods located on the same fixed base. Elastic elements are fitted onto both guide rods and the threaded rods, and the two ends of the elastic elements are respectively connected to the connecting plate and the fixed base.

[0007] As a further preferred embodiment, the testing mechanism includes support rods, annular guide rails, sliding rings, gear rings, rotating shafts, gears, servo motors, pulley assemblies, and an industrial camera. Two support rods are fixedly connected to the testing box, and annular guide rails are fixedly connected to the support rods. A sliding ring is rotatably mounted on the annular guide rails, and a gear ring is fixedly connected to the sliding ring. An industrial camera is mounted on the sliding ring and is electrically connected to a controller. A rotating shaft is rotatably mounted on the testing box, and two gears are fixedly connected to the rotating shaft. The gears mesh with adjacent gear rings. A servo motor is installed inside the control box, and a pulley assembly is provided between the output shaft of the servo motor and the rotating shaft.

[0008] As a further preferred option, it also includes an audible and visual alarm and contact switches. The detection box is equipped with an audible and visual alarm and multiple contact switches, which are electrically connected to the controller.

[0009] As a further preferred option, a protective door is also included, with the testing box having a hinged protective door.

[0010] As a further preferred option, multiple pads are fixedly connected to the support base.

[0011] As a further preferred option, the control box is equipped with a hinged rotating door.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The tin-plated copper wire squeezes the arc-shaped clamping plate outward, and at the same time the arc-shaped clamping plate drives the threaded rod and two guide rods on its own to move outward. The elastic element is compressed and quickly rebounds, so that the elastic element drives the threaded rod, two guide rods and arc-shaped clamping plate to move inward, thereby limiting and fixing the tin-plated copper wire, thus avoiding the breakage of the tin-plated copper wire due to uneven tension, and avoiding affecting the quality of the tin-plated copper wire.

[0013] 2. By starting the servo motor, the output shaft of the servo motor drives the rotating shaft to rotate through the pulley assembly. The rotating shaft drives two gears to rotate, and the gears mesh with the gear ring, causing the gear ring to drive the sliding ring and the industrial camera above it to rotate. This enables comprehensive inspection of the tin-plated copper wire, thereby ensuring inspection accuracy and preventing defective products from entering the market.

[0014] 3. The curved clamping plate drives the threaded rod to move outward. When the curved clamping plate squeezes the contact switch, the contact switch will activate the audible and visual alarm through the controller, thereby indicating that there is an area with excessively thick plating on the tinned copper wire, so that the staff can be notified in time to deal with it.

Detailed Implementation

[0022] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0023] Example 1: A device for detecting surface defects in tin-plated copper wire, see reference. Figures 1-6As shown, the device includes a support base 1, a control box 2, a detection box 3, a mounting base 4, guide wheels 5, a controller 501, an industrial display screen 6, and a detection mechanism. The control box 2 is welded to the middle of the support base 1, and the detection box 3 is welded to the upper part of the support base 1. Mounting bases 4 are symmetrically fixed to the top and bottom of the detection box 3. Guide wheels 5 are rotatably mounted on the mounting bases 4. The controller 501 is mounted on the rear top of the detection box 3, and the industrial display screen 6 is mounted on the controller 501. The controller 501 is electrically connected to the industrial display screen 6. The detection mechanism for detection is located inside the detection box 3, and it also includes a fixed base 15, a guide rod 16, a connecting plate 17, and an elastic... The test box 3 is equipped with three fixed seats 15, which are evenly spaced and fixedly connected to the top and bottom. The three fixed seats 15 are staggered with the two annular guide rails 8. The fixed seat 15 is rotatably mounted with a threaded rod 19 in the middle. The threaded rod 19 is threaded with an arc-shaped clamp 20. Two adjacent arc-shaped clamps 20 fit together. The fixed seat 15 is slidably mounted with guide rods 16 at both the front and rear. The two guide rods 16 and the threaded rod 19 located on the same fixed seat 15 are fixedly connected with a connecting plate 17. The two guide rods 16 and the threaded rod 19 are fitted with elastic elements 18. The two ends of the elastic elements 18 are connected to the connecting plate 17 and the fixed seat 15, respectively.

[0024] See Figure 1 As shown, it also includes a protective door 23, which is hinged to the front of the detection box 3.

[0025] See Figure 1 As shown, four pads are fixedly connected at even intervals at the bottom of the support base 1. The pads increase the friction between the support base 1 and the ground, thereby preventing the position of the support base 1 from easily shifting.

[0026] See Figure 1 As shown, the control box 2 is equipped with a hinged rotating door to facilitate the maintenance of the servo motor 13.

[0027] When surface defect detection of tin-plated copper wire is required, the tin-plated copper wire is first inserted into the detection box 3, passing through two guide rollers 5 and two annular guide rails 8. At the same time, the detection mechanism performs surface defect detection on the tin-plated copper wire and transmits the detection data to the controller 501, which then transmits the data to the industrial display screen 6 for display. When the tin-plated copper wire is inserted into the detection box 3, it passes through the two guide rollers 5 and between multiple annular clamps. During insertion, the tin-plated copper wire squeezes the arc-shaped clamp 20 outward, and at the same time, the arc-shaped clamp 20 drives the threaded rod 19 and two guide rods 16 on its own to move outward. The elastic element 18 is compressed and quickly rebounds, causing the elastic element 18 to drive the threaded rod 19, the two guide rods 16 and the arc-shaped clamp 20 to move inward, thereby limiting and fixing the tin-plated copper wire, thus preventing the tin-plated copper wire from breaking due to uneven tension and avoiding affecting the quality of the tin-plated copper wire.

[0028] Example 2: Based on Example 1, refer to Figures 2-5 As shown, the detection mechanism includes support rods 7, annular guide rails 8, sliding rings 9, gear rings 10, rotating shafts 11, gears 12, servo motors 13, pulley assembly 1301, and industrial cameras 14. Support rods 7 are symmetrically fixed to the bottom of the detection box 3, with two support rods 7 positioned between four mounting bases 4. Annular guide rails 8 are fixedly connected to the top of the support rods 7. Sliding rings 9 are rotatably mounted on the annular guide rails 8. Gear rings 10 are fixedly connected to the right side of the sliding rings 9. Industrial cameras 14 are bolted to the sliding rings 9. 4 is electrically connected to the controller 501. A rotating shaft 11 is rotatably installed in the rear of the detection box 3. Gears 12 are fixedly connected to both the left and right sides of the rotating shaft 11. The gears 12 mesh with the adjacent gear ring 10. A servo motor 13 is installed at the bottom of the control box 2 by bolt connection. A pulley assembly 1301 is installed between the output shaft of the servo motor 13 and the rotating shaft 11. The pulley assembly 1301 consists of two pulleys and a flat belt. The two pulleys are respectively installed in the middle of the rotating shaft 11 and on the output shaft of the servo motor 13. The flat belt is wound around the two pulleys.

[0029] During testing, the servo motor 13 is activated, and its output shaft drives the rotating shaft 11 to rotate via the pulley assembly 1301. The rotating shaft 11 drives two gears 12 to rotate, and the gears 12 mesh with the gear ring 10, causing the gear ring 10 to drive the sliding ring 9 and the industrial camera 14 above it to rotate. This allows for comprehensive testing of the tin-plated copper wire, ensuring testing accuracy and preventing defective products from entering the market. After testing, the servo motor 13, industrial camera 14, and industrial display screen 6 are turned off, and the components inside the testing box 3 can be easily inspected and repaired through the protective door 23.

[0030] See Figure 1 Diagram and Figure 4 As shown, it also includes an audible and visual alarm 21 and a contact switch 22. The audible and visual alarm 21 is installed on the top left side of the detection box 3 by means of bolt connection. Three contact switches 22 are evenly spaced on the top and bottom of the detection box 3. The contact switches 22 and the nearby threaded rods 19 are located on the same vertical line. The contact switches 22 are electrically connected to the controller 501.

[0031] When the tinned copper wire squeezes the arc-shaped clamp 20, the arc-shaped clamp 20 drives the threaded rod 19 to move outward. When the arc-shaped clamp 20 squeezes the contact switch 22, the contact switch 22 will activate the audible and visual alarm 21 through the controller 501, thereby indicating that there is an area of ​​excessive plating on the tinned copper wire, so that the staff can be notified in time to deal with it.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
