[0031] like Figures 1 to 5 As shown, the visual inspection machine 1 provided in this application includes:

[0032] Rack 10;

[0033] Testing unit 30 is located on frame 10;

[0034] The unloading mechanism 50 is located on the frame 10. The unloading mechanism 50 includes a drive component 51 and a docking belt 53. The drive component 51 is connected to the docking belt 53 to drive the docking belt 53 to move. One end of the docking belt 53 is connected to the unloading port of the detection mechanism 30, and the other end is used to dock with the inlet of external equipment.

[0035] The visual inspection system includes a frame 10, an inspection mechanism 30, and a feeding mechanism 50. The frame 10 serves as the basic support structure for the equipment, providing mounting positions for other components. The inspection mechanism 30 is used for visual inspection of inductors and is a key functional component of the equipment. The feeding mechanism 50 is responsible for conveying the inspected products from the inspection mechanism 30 to external equipment. A drive unit 51 drives the docking belt 53 to move, achieving automatic product transfer and changing the traditional manual handling method of unloading, thus improving production efficiency.

[0036] The frame 10 is the basic support structure of the entire visual inspection machine 1, providing a platform for the installation and fixation of other components such as the inspection mechanism 30 and the unloading mechanism 50. Its stability and strength directly affect the operational reliability and service life of the entire equipment. Different equipment designs and application scenarios have different requirements for the material, shape, and size of the frame 10.

[0037] Regarding the material of the frame 10, high-strength aluminum alloy can be selected, which is lightweight, facilitates equipment movement and installation, and has good corrosion resistance, adapting to different production environments; alternatively, high-quality steel, such as Q345 steel, can be used, which has high strength and can withstand greater weight and external impact, suitable for large, high-precision visual inspection machines 1. In terms of shape design, depending on the layout requirements of the equipment's functional modules, it can be designed as a frame type, cantilever type, etc. The frame type structure has good stability and facilitates the installation and maintenance of various components; the cantilever type structure saves space and allows operators to easily operate and maintain the equipment from one side.

[0038] The inspection mechanism 30 is the core component for realizing the appearance inspection function of inductors, responsible for inspecting the appearance shape, size, surface defects, etc. of the inductors. Its inspection accuracy, speed, and reliability determine the performance of the entire appearance inspection machine 1. The inspection mechanism 30 typically includes inspection equipment and related control systems. The inspection equipment can be a vision inspection camera, laser measuring instrument, etc., and the control system is used to control the operation of the inspection equipment, data acquisition, and analysis.

[0039] The unloading mechanism 50 is responsible for conveying the tested inductors from the testing mechanism 30 to external equipment. Its key components are the drive unit 51 and the docking belt 53. The drive unit 51 provides power for the movement of the docking belt 53, which in turn enables the transfer of products. The operating efficiency and stability of the unloading mechanism 50 directly affect the continuity of the entire production process.

[0040] Regarding the drive component 51 of the feeding mechanism 50, in addition to the common motor, hydraulic or pneumatic drives can also be used. Hydraulic drives have greater driving force and are suitable for applications requiring the transport of heavier products or high-force transmission; pneumatic drives offer faster response, lower cost, and simpler maintenance, making them suitable for applications with higher speed requirements and lower loads. The expansion of the docking belt 53 includes increasing its load-bearing capacity and adaptability. For example, using a high-strength conveyor belt material 531, such as a steel cord conveyor belt 531, can improve the strength and wear resistance of the docking belt 53, enabling it to carry heavier products; adjustable separators can be installed on the docking belt 53 to adjust the spacing according to different sizes of inductive products, improving the adaptability of the docking belt 53 to different product specifications. Furthermore, an automatic counting device can be installed on the docking belt 53 to count the number of products transported in real time, facilitating production management and quality control.

[0041] Furthermore, the driving component 51 is a motor, and the output shaft of the motor is connected to the transmission roller of the mating belt 53 via a coupling.

[0042] Specifically, the drive component 51 is a motor, and the motor output shaft is connected to the drive roller of the docking belt 53 via a coupling. The motor can provide stable and continuous power, while the coupling can compensate for installation errors between the motor and the drive roller, buffer vibration, ensure smooth power transmission, and enable the docking belt 53 to run at a uniform speed and reliably, ensuring the stability of product conveying.

[0043] Optionally, a high-performance brushless DC motor is selected, which offers higher efficiency, more precise speed control, and a longer service life compared to AC motors. The coupling uses a diaphragm coupling, which effectively compensates for installation misalignment between the motor output shaft and the drive roller, providing excellent shock absorption and buffering performance, reducing vibration and noise during equipment operation. The drive roller is made of seamless steel tubing with a chrome-plated surface to improve hardness and wear resistance. Deep groove ball bearings are installed at both ends of the drive roller to ensure flexible rotation and reduce frictional resistance.

[0044] Furthermore, the docking belt 53 includes a conveyor belt 531 and limiting clamping plates 533 located on both sides of the conveyor belt 531. The limiting clamping plates 533 and the conveyor belt 531 are fixedly connected by a connecting bracket.

[0045] Specifically, the docking belt 53 consists of a conveyor belt 531 and two limiting clamping plates 533 on both sides, which are fixedly connected by a connecting bracket. The conveyor belt 531 is responsible for carrying and conveying the product, while the limiting clamping plates 533 can prevent the product from deviating during the conveying process, ensuring that the product is always transmitted on the predetermined path, improving the accuracy of product conveying, and ensuring that the product can accurately dock with the feed port of external equipment.

[0046] Optionally, the conveyor belt 531 is a 5mm thick, PVC-made circular belt with good flexibility and weather resistance. The limit clamping plate 533 is made of stainless steel, stamped and formed, with a smooth, burr-free surface to prevent scratching the product. The connecting bracket is an L-shaped structure made of aluminum alloy, connected to the conveyor belt 531 and the limit clamping plate 533 by bolts and nuts, facilitating easy installation and disassembly, and simplifying future maintenance and component replacement. Rubber buffer blocks are spaced apart on the inner side of the limit clamping plate 533 to further protect the product from damage during transport.

[0047] Furthermore, the conveyor belt 531 is provided with several grooves for placing products.

[0048] Specifically, grooves are provided on the conveyor belt 531 for placing products. The grooves can position the products, making them more stable during the conveying process and preventing positional deviations caused by the shaking of the conveyor belt 531 or the sliding of the products themselves. This further improves the reliability of product conveying, and is especially suitable for inductor products with regular shapes.

[0049] Optionally, the groove is custom-designed according to the shape and size of the inductor. For cylindrical inductors, the groove is semi-circular with a radius 0.5mm larger than the inductor's radius, ensuring stable placement without wobbling. For square inductors, the groove is square with a side length 1mm larger than the inductor's side length. The groove depth is one-third of the inductor's height, effectively securing the product without interfering with loading and unloading operations. A layer of elastic silicone pad is placed at the bottom of the groove to further enhance protection and fixation of the product.

[0050] Furthermore, an elastic buffer layer is provided on the inner side of the limiting clamping plate 533, and the elastic buffer layer is made of rubber or silicone.

[0051] Specifically, the elastic buffer layer on the inner side of the limiting clamping plate 533 is made of rubber or silicone. During product transportation, the elastic buffer layer can prevent the limiting clamping plate 533 from colliding hard with the product, prevent the product surface from being scratched or damaged, protect the product's appearance quality, and at the same time reduce the vibration caused by the collision to a certain extent, ensuring the integrity of the product during transportation.

[0052] Furthermore, the docking belt 53 also includes an adjusting screw, which is movably connected to two limiting clamping plates 533 respectively, and the distance between the two limiting clamping plates 533 can be adjusted by the adjusting screw.

[0053] Specifically, the mating belt 53 is equipped with an adjusting screw, which movably connects two limit clamping plates 533 and adjusts their spacing. This allows the equipment to adapt to inductor products of different sizes, improving its versatility. When producing products of different specifications, companies do not need to change the equipment; they can adjust the spacing of the limit clamping plates 533 simply by adjusting the screw, reducing production costs and enhancing the equipment's market competitiveness.

[0054] Optionally, the adjusting screw is made of high-strength carbon steel with a blackened surface to increase rust resistance. One end of the screw is machined with external threads to mate with the threaded hole on the limit clamping plate 533, and the other end is equipped with a handwheel for easy manual adjustment. Two guide rods are also provided between the two limit clamping plates 533, parallel to the adjusting screw. The limit clamping plates 533 are mounted on the guide rods via linear bearings, ensuring smooth movement of the limit clamping plates 533 during adjustment without deviation.

[0055] Furthermore, the top of the limiting clamping plate 533 is provided with a guide bevel 5331, which is located on the side close to the conveyor belt 531.

[0056] Specifically, the guide bevel 5331 at the top of the limiting clamping plate 533 is set near the side of the conveyor belt 531. When the product enters the conveyor belt 531, the guide bevel 5331 can guide the product smoothly into the area between the limiting clamping plates 533, reducing the probability that the product cannot be accurately clamped due to positional deviation, improving the smoothness of product conveying, reducing the occurrence of product jamming or falling, and ensuring the continuity of the production process.

[0057] Optionally, the guide bevel 5331 has an inclination angle of 45°, is integrally formed from stainless steel, and is welded and fixed to the limiting clamping plate 533. A layer of hard chrome plating is applied to the surface of the guide bevel 5331 to make it smoother and reduce friction between the product and the guide bevel 5331. The guide bevel 5331 has a width of 30mm, which effectively guides the product smoothly into the area between the limiting clamping plates 533, improving the accuracy and smoothness of product conveying.

[0058] Furthermore, the surface of the guide bevel 5331 is provided with a smooth coating.

[0059] Specifically, the smooth coating on the surface of the guide bevel 5331 reduces the friction between the product and the guide bevel 5331, allowing the product to enter the limiting area more smoothly along the guide bevel 5331. This not only helps improve product conveying efficiency but also prevents damage to the product surface due to excessive friction, further ensuring product quality.

[0060] Optionally, the smooth coating is made of polytetrafluoroethylene (PTFE) and is evenly applied to the surface of the guide bevel 5331 using a spraying process, with a coating thickness of 0.1 mm. PTFE has an extremely low coefficient of friction, which allows the product to slide more smoothly on the guide bevel 5331. It also has good corrosion resistance and self-cleaning properties, making it less prone to dust and oil contamination, thus ensuring the cleanliness and hygiene of the equipment.

[0061] Furthermore, the limiting clamping plate 533 and the conveyor belt 531 are both made of stainless steel or engineering plastics.

[0062] Specifically, stainless steel or engineering plastics are selected as the materials for the limit clamping plate 533 and the conveyor belt 531. Stainless steel has good corrosion resistance, high strength, and easy cleaning, while engineering plastics have the characteristics of light weight, low cost, and good insulation. These materials can adapt to the environment of the inductor production workshop, ensure the long-term stable operation of the equipment, reduce equipment maintenance costs, and extend the service life of the equipment.

[0063] Furthermore, the feeding mechanism 50 also includes a guide plate 55, which is located on the side of the docking belt 53 near the feeding port of the detection mechanism 30, and the guide plate 55 is inclined toward the docking belt 53.

[0064] Specifically, the guide plate 55 added to the unloading mechanism 50 is located on the side of the docking belt 53 near the unloading port of the inspection mechanism 30 and is inclined towards the docking belt 53. It can guide the inspected products to fall smoothly onto the docking belt 53, prevent the products from falling to other positions, ensure that the products accurately enter the conveying process of the docking belt 53, improve the success rate of product conveying, and ensure the smooth operation of production.

[0065] Optionally, the guide plate 55 is made of acrylic material, which has good transparency, allowing operators to easily observe the product conveying process. The guide plate 55 has a 30° tilt angle and is fixed to the frame 10 with bolts and nuts. The installation angle can be finely adjusted according to actual needs. A smooth PEEK film is adhered to the surface of the guide plate 55 to further reduce the friction between the product and the guide plate 55, ensuring that the product can smoothly slide onto the docking belt 53. The width of the guide plate 55 is slightly larger than the width of the docking belt 53 to ensure that the product does not fall off the sides of the guide plate 55.
