In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0049] See also Figure 1-6 In a flexible cable appearance automatic inspection device, it is mainly composed of a base 1, a top platform 2 and four corner support pillars 11. This structural design not only ensures the stability and durability of the entire device. The base 1 provides the basic support of the device, while the top platform 2 plays a key role in connecting and fixing the internal mechanical components.

[0050] Between the base 1 and the top platform 2, there is a lifting platform 4, which can be lifted and driven in the vertical direction, so that it can drive the flexible cable pressing plate 6 to press on the top surface of the flexible cable placement platform 3. A flexible cable pressing plate 6 is installed below the lifting platform 4, and the flexible cable pressing plate 6 can effectively press the flexible cable placed thereon to ensure the accuracy of the detection. At the center of the lifting platform 4, there is a detection camera 5, which is responsible for capturing the image of the flexible cable and transmitting the image data to the back-end image processing system for analysis, thereby realizing automatic detection of the appearance quality of the flexible cable.

[0051] In order to ensure the flatness of the flexible cable during the inspection process, elastic connectors 7 are installed at the four corners between the flexible cable pressing plate 6 and the lifting platform 4. These elastic connectors 7 can not only maintain the stability of the pressing plate, but also automatically adjust the pressure according to the thickness of the flexible cable to avoid damaging the cable due to excessive pressure. The core part of the elastic connector 7 includes a through-hole column 71, a limit cap 73 and a spring 72, wherein the spring 72 provides the necessary elasticity for the entire connector, so that the flexible cable pressing plate 6 can press the flexible cable on the surface of the flexible cable placement platform 3 below.

[0052] The downward pressing transmission member 8 is a key mechanism connecting the lifting platform 4 and the top platform 2. It realizes the downward pressing driving operation of the lifting platform 4 through the coordinated work of the rotary disk 81, the docking shaft 82 and the connecting rod 83. The rotation of the rotary disk 81 can drive the docking shaft 82 to change its position, and then transmit power through the connecting rod 83, and finally convert the rotation into an up and down linear driving force through the action of the articulated seat 84, thereby realizing the lifting and lowering operation of the lifting platform 4, ensuring the flatness and stability of the flexible cable during the flattening process.

[0053] The driving assembly 9 is the power source of the entire device, which includes a stepper motor 91, a driving gear 92 and a transmission gear 93. The high-precision control capability of the stepper motor 91 ensures the operating efficiency and stability of the entire downward pressure transmission system, and the 1:1 transmission ratio design makes the rotation control of the rotary disk 81 more precise, thereby ensuring that the detection camera 5 can capture the image of the flexible cable at the best position.

[0054] Guide columns 41 are provided on the left and right sides of the top of the lifting platform 4. These guide columns are slidably connected to the inside of the top platform 2, providing precise guidance for the up and down movement of the lifting platform 4, ensuring the stability and reliability of the entire detection process.

[0055] Additional information on the working principle:

[0056] When starting a detection cycle, the operator places the flexible cable to be tested flat on the flexible cable placement table 3, which is specially designed to adapt to the physical characteristics of the flexible cable to ensure that the position of the cable is accurate and stable during the detection process. Subsequently, after the drive component 9 receives the detection instruction, the stepper motor 91 is started, and the drive shaft 94 transmits the rotational power to the turntable 81 through the meshing rotation of the drive gear 92 and the transmission gear 93. The rotation of the turntable 81 drives the articulated seat 84 and the lifting platform 4 through the synergistic effect of the docking shaft 82 and the connecting rod 83, thereby realizing the precise downward pressure of the lifting platform 4 and the flexible cable pressing plate 6.

[0057] When the flexible cable pressing plate 6 is pressed down, the spring 72 in the elastic connector 7 will deform appropriately according to the pressing force. This design can ensure the pressing force, avoid damage to the flexible cable, and can also flatten the flexible cable to ensure the accuracy of subsequent inspections. When the flexible cable is flattened, the advantage of the detection camera 5 being located at the center of the lifting platform 4 becomes apparent. Through the flattening transparent plate 61 located at the center of the flexible cable pressing plate 6, the camera can clearly capture the surface condition of the flexible cable, and can detect both slight scratches and tiny impurities.

[0058] The captured image data is then transmitted to the image processing system, which uses advanced image recognition and processing technology to analyze the data and identify any defects or irregularities on the surface of the flexible cable. After the inspection is completed, the drive assembly 9 drives the lifting platform 4 and the pressing plate 6 to return to the initial position and wait for the next inspection.
