Description

Technical Field

[0001] This utility model relates to cable surface defect detection equipment, specifically a cable surface detection device. Background Technology

[0002] Currently, in the industrial manufacturing sector, especially in the production of high-voltage cables and optical fibers, surface defect detection mainly relies on manual labor. However, this method has several limitations:

[0003] ① Traditional manual quality inspection is inefficient and difficult to guarantee accuracy: It requires dedicated personnel to monitor the product surface continuously 24 hours a day to detect defects in a timely manner. However, due to factors such as personnel fatigue and distraction, problems such as untimely warnings and inability to guarantee detection accuracy occur frequently.

[0004] ② The cost of manual quality inspection is high: In order to meet the needs of 24-hour continuous operation of the production line, companies usually need to configure at least three full-time quality inspectors to work in shifts, which significantly increases labor costs and imposes an economic burden on the company's operations.

[0005] ③ Influenced by external environmental and personal factors: For example, changes in temperature and lighting conditions in the work environment, as well as the emotional state and sense of responsibility of quality inspectors, can all affect the final detection rate. Especially in some extreme or dangerous work environments, manual inspection is neither safe nor feasible.

[0006] ④ The problems in data storage and management are also very prominent: the manual recording of defect information is prone to data loss, omission and incomplete storage, which greatly limits the possibility of subsequent data analysis and utilization, reflecting the low level of digitization in the whole process.

[0007] ⑤ Although traditional 2D optical inspection technology can improve inspection efficiency and accuracy to a certain extent, it has obvious shortcomings in handling complex geometries, surface textures and depth information, making it difficult to achieve a comprehensive assessment of product surface defects.

[0041] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] Example:

[0044] As attached Figure 1 and 6As shown, this embodiment provides a cable surface inspection device, the structure of which includes a chassis 1, a display 2 mounted on the top of the chassis 1, an industrial control computer 3 at the bottom of the chassis 1, cable inlets 4 and cable outlets 5 respectively opened on the two side walls of the chassis 1, the cable inlets 4 and cable outlets 5 are located in the lower middle part of the chassis 1, and an image acquisition component is installed at each of the cable inlets 4 and cable outlets 5; the image acquisition component includes an image acquisition bracket 6, one side of the image acquisition bracket 6 is fixedly connected to the inner side wall of the chassis 1, and several adjustable camera mounting mechanisms are mounted on the other side of the image acquisition bracket 6 in a circumferential array, and a laser profilometer 7 is mounted on the adjustable camera mounting mechanism; six cooling fans 8 in a circumferential array are installed at the cable inlets 4 and cable outlets 5 respectively, the cooling fans 8 are arranged one-to-one with the laser profilometers 7 and the cooling fans 8 are mounted on the side wall of the chassis 1, as shown in the attached figure. Figure 4 As shown. Among them, the cooling fan 8 is installed directly on the key heat-generating area of ​​the laser profilometer 7, which can effectively remove heat from the area around the camera and keep its operating temperature within an ideal range. This is crucial for maintaining the accuracy and stability of the laser profilometer 7, especially in application scenarios where it operates continuously for a long time.

[0045] In this embodiment, a total of six laser profilometers 7 are mounted at different positions on the camera bracket 11, forming a surround scanning array. This layout ensures that surface information of the target object is acquired simultaneously from multiple angles, thereby improving the comprehensiveness and accuracy of data acquisition. Each laser profilometer 7 is calibrated to ensure that the output data is consistent and highly accurate. Grouping strategy: Each opposing laser profilometer group 7 is assigned a different trigger frequency. For example, taking six laser profilometers 7 as an example, these six laser profilometers 7 can be labeled as A, B, C, D, E, and F, where A and D, B and E, and C and F are each a group. Each group of laser profilometers 7 is assigned a specific trigger frequency. For example, A and D use frequency f1, B and E use frequency f2, and C and F use frequency f3. The selection of frequency needs to consider factors such as ambient light conditions and camera sensor characteristics to ensure optimal performance; the trigger frequency of each camera group is adjusted in real time according to the image quality and interference situation during actual operation. For example, if interference is found between a certain group of laser profilometers 7, the frequency difference between that group and other groups is appropriately increased.

The encoder wheel bracket 9 is located in the upper middle part of the outer wall of the chassis 1, and an encoder 10 is mounted on it.

The encoder wheel bracket 9 is preferably made of high-strength metal material to ensure sufficient mechanical strength and stability. The encoder wheel bracket 9 is designed with a modular structure, supporting quick disassembly, installation, and replacement for easy maintenance or upgrades. The encoder 10, mounted on the encoder wheel bracket 9, is a high-precision rotary sensor capable of accurately detecting and outputting position information or speed signals. The encoder 10 can be selected as an incremental or absolute encoder, depending on the requirements of the actual application scenario. For example, in applications requiring precise positioning, an absolute encoder with a resolution of thousands of pulses per revolution can be selected.

[0049] As attached Figure 9 As shown, in this embodiment, a Y-axis angle adjustment plate 20 is installed on the upper surface of the connecting plate 17. The Y-axis angle adjustment plate 20 has symmetrically opened Y-axis angle adjustment arc holes 21, and Y-axis angle adjustment locking bolts 22 are installed in the Y-axis angle adjustment arc holes 21. An X-axis front and rear adjustment plate 23 is installed on the lower side of the Y-axis angle adjustment plate 20. X-axis front and rear adjustment elongated holes 24 are opened at the four corners of the X-axis front and rear adjustment plate 23, and X-axis front and rear adjustment locking bolts 25 are installed in the X-axis front and rear adjustment elongated holes 24. The base end of the laser profilometer 7 is detachably connected to the X-axis front and rear adjustment plate 23 through the X-axis front and rear adjustment locking bolts 25.

[0050] As attached Figure 2As shown, in this embodiment, a sliding door 26 is installed on the rear side of the chassis 1, and a multi-functional integrated panel 27 is installed on the upper part of the center of the front side of the chassis 1.
