Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to an online detection device for cable surface defects. Background Technology

[0002] During cable production, the cable surface should ideally be smooth and uniform to ensure its physical and electrical insulation properties. However, due to various factors, defects may appear on the cable surface. For example, during the extrusion coating process, air may become trapped within the coating and fail to escape, resulting in air bubbles on the cable surface. These bubbles can lead to localized insulation problems and affect the cable's electrical performance. Therefore, it is necessary to detect defects on the cable surface. In existing systems, multiple detection devices are typically located on both sides of the detection chamber. While these devices can detect the cable surface entering and exiting the chamber, they may also miss some defects or be insensitive to small defects. Furthermore, existing devices can only detect one or a specific type of cable. When different cable models need to be tested, recalibration or adjustment of the equipment may be required, thus reducing the device's adaptability.

[0003] Therefore, in order to further improve the practicality and adaptability of the device, we provide an online cable surface defect detection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an online detection device for cable surface defects. This device uses a movable electric ring slide rail inside the detection chamber, connected to a vision sensor, to detect the cable body in a 360-degree direction. The slide rail then drives the vision sensor to detect the cable body in a left-right direction. This avoids the insensitivity and missed detection issues that some devices may have in identifying small or minute defects. Furthermore, the interaction of compression springs and extrusion plates inside the inlet and outlet coils allows the detection device to be used with different types of cables, further improving its practicality and adaptability. Additionally, a sponge ring is placed on the outer surface of the inlet coil to transport the cleaned cable into the detection chamber, preventing the detection process from being affected by external environmental factors (such as humidity, temperature, and dust), which could reduce the accuracy of the detection.

[0005] This utility model also provides an online detection device for cable surface defects, comprising: a detection cabinet, wherein the detection cabinet has a detection chamber inside, a slide rail is fixedly connected to the inner bottom surface of the detection chamber, an electric ring slide rail is slidably connected to the surface of the slide rail via an electric slider, a vision sensor is fixedly connected to the inner surface of the electric ring slide rail via a slider, two slide rails are symmetrically arranged vertically, a lamp wire groove is fixedly connected to the inner bottom surface of the detection chamber, an LED light is fixedly connected to the outer surface of the lamp wire groove, and an inlet coil is fixedly connected to the side of the detection cabinet, the inlet coil being composed of a compression spring and a pressing plate.

[0006] According to the online cable surface defect detection device of this utility model, the cable body passes through the interior of the inlet coil, one end of the compression spring is fixedly connected to the inner surface of the inlet coil, and the other end is fixedly connected to the compression plate. It is suitable for cables of different types or specifications.

[0007] According to the online cable surface defect detection device of this utility model, the extrusion plate is arc-shaped, and the inner surface of the extrusion plate is in contact with the surface of the cable body. This facilitates contact with the cable body and protects the outer surface of the cable body from damage.

[0008] According to the online cable surface defect detection device of this utility model, a display panel is provided on the upper surface of the detection cabinet. This panel is used to display and transmit the data and signals after detection, reminding operators to check and process them.

[0009] According to the online cable surface defect detection device of this utility model, an outlet coil is fixedly connected to the side of the detection cabinet away from the inlet coil. This facilitates the overall detection of the cable body.

[0010] According to the online cable surface defect detection device of this utility model, the inlet coil and the outlet coil have the same shape and structure, and sponge rings are fixedly connected to the outer surfaces of the inlet coil and the outlet coil, respectively. This is to facilitate the cleaning of impurities and dust adhering to the surface of the cable body before it enters the detection chamber.

[0011] According to the online cable surface defect detection device of this utility model, the length of the slide rail is the same as the length of the detection chamber, and the slide rail is located at the center of the detection chamber. This is used to correspond to the positions of the inlet coil and the outlet coil.

[0012] According to the online cable surface defect detection device of this utility model, the number of LED lights is several, the lampshade opening of each LED light corresponds to the cable body, and the lamp groove is located on the side of the cable body. This is used to reduce light shadows and reflections, helping to reveal minute defects.

[0013] Beneficial effects: By installing a movable electric ring slide rail inside the inspection chamber and connecting it to a vision sensor to inspect the cable body in 360 degrees, and then using the slide rail to drive the vision sensor to inspect the cable body in the left and right directions, the device avoids the situation where some devices are not sensitive enough in identifying small or minute defects and may miss detections. In addition, the interaction of compression springs and extrusion plates installed inside the inlet and outlet coils makes the inspection device applicable to different types of cables, further improving the practicality and adaptability of the device. Furthermore, a sponge ring is placed on the outer surface of the inlet coil to transport the cleaned cable into the monitoring chamber, avoiding the influence of external environmental factors (such as humidity, temperature, and dust) on the inspection process and reducing the accuracy of the inspection.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model embodiment of the online cable surface defect detection device includes: a detection cabinet 1, with a detection chamber 2 inside the cabinet 1. The detection chamber 2 operates synchronously with the cable production process. When the cable enters the detection chamber 2, a vision sensor 7 captures the state information of the cable surface and sends this information to a display panel 11. The detected information is recorded and displayed on the display panel 11 for timely alerts and real-time identification of defects such as cracks and bubbles on the cable surface. A slide rail 8 is fixedly connected to the inner bottom surface of the detection chamber 2 to facilitate the movement of an electric ring slide rail 6 and the vision sensor 7, making the detection results more accurate. The surface of the slide rail 8 is slidably connected to the electric ring slide rail 6 via an electric slider, facilitating the vision sensor 7 to inspect the cable body 3. The 360-degree inspection is achieved by fixing a vision sensor 7 to the inner surface of the electric ring slide rail 6 via a slider. This sensor scans and inspects the surface of the cable body 3. Two slide rails 8 are symmetrically arranged vertically to maintain the stability of the electric ring slide rail 6. A lamp wire groove 9 is fixedly connected to the inner bottom surface of the inspection chamber 2 to facilitate the connection of LED lights 10. An LED light 10 is fixedly connected to the outer surface of the lamp wire groove 9. The adjustable light intensity of the LED light 10 ensures that clear images can be obtained in conjunction with the vision sensor 7 under different environmental conditions. An inlet coil 4 is fixedly connected to the side of the inspection cabinet 1. The inlet coil 4 is composed of a compression spring 41 and a squeezing plate 42, which is suitable for different types of cable bodies 3 to enter the inspection chamber 2 for inspection.

[0023] The cable body 3 runs through the inside of the inlet coil 4. One end of the compression spring 41 is fixedly connected to the inner surface of the inlet coil 4, and the other end is fixedly connected to the extrusion plate 42. This adapts to different types or specifications of cables, improving the practicality of the testing device. The extrusion plate 42 is arc-shaped, and its inner surface fits against the surface of the cable body 3. This facilitates contact with the cable body 3 and protects the outer surface of the cable body 3 from damage. A display panel 11 is installed on the upper surface of the testing cabinet 1. This panel displays and transmits the data and signals after testing, reminding operators to check and process them. An outlet coil 401 is fixedly connected to the side of the testing cabinet 1 away from the inlet coil 4. This facilitates the overall testing of the cable body 3. The inlet coil 4 and the outlet coil 401 have the same shape and structure. Sponge rings 5 ​​are fixedly connected to the outer surfaces of the inlet coil 4 and the outlet coil 401, respectively. These rings clean impurities and dust adhering to the surface of the cable body 3 before it enters the testing chamber 2, preventing inaccurate testing. The length of the slide rail 8 is the same as the length of the inspection chamber 2. The slide rail 8 is located at the center of the inspection chamber 2 and is used to correspond to the positions of the inlet coil 4 and the outlet coil 401 to ensure the smooth transport of the cable body 3. There are several LED lights 10. The lamp cover opening of the LED light 10 corresponds to the cable body 3. The position of the lamp wire groove 9 is located on the side of the cable body 3 to reduce light shadows and reflections, help to reveal small defects, ensure clear images under different environmental conditions, and help improve the performance and accuracy of the inspection equipment.

[0024] Working principle: When using this online cable surface defect detection device, the cable body 3 enters through the inlet coil 4 of the detection cabinet 1 and exits through the outlet coil 401. The sponge ring 5 cleans the impurities and dust attached to the surface of the cable body 3 before it enters the detection chamber 2. At the same time, the electric ring slide rail 6 drives the vision sensor 7 to detect the outer surface of the cable body 3. Meanwhile, the electric ring slide rail 6 moves left and right using the slide rail 8 to ensure that all angles of the cable body 3 can be detected. When the cable body 3 passes through the inside of the inlet coil 4, the compression plate 42 compresses the compression spring 41 to adjust and adapt to different types of cables. Combined with the LED light 10 providing light source around the cable body 3, it helps to improve the accuracy of the detection.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
