[0038] In one embodiment of the present invention, Figures 1 to 10 As shown, there is provided an automatic line for testing finished magnetic devices, including a loading device 10, a laser coding scanner 20, a testing device 30, a transport device 40, a visual inspection system 50 and an unloading device 60. The loading device 10 is provided with a loading position for stably conveying the product 1 to be tested to the next station. The laser coding scanner 20 is located on the conveying path of the loading device 10, and is used to code the product 1 to be tested at the loading position and scan the code to generate a corresponding identification code of the product 1; the testing device 30 includes a withstand voltage test mechanism 31 and a disc comprehensive test mechanism 32 arranged in sequence; the withstand voltage test mechanism 31 is used to detect whether the withstand voltage performance of the product 1 is qualified; the disc comprehensive test mechanism 32 is used to test whether the comprehensive performance of the product 1 is qualified; the transport device 40 is used to take out the product 1 to be tested for which the identification code has been generated by the loading device 10 and transport it to the testing device 30 for testing, and to remove the product 1 to be tested after the test.

[0039] Specifically, the loading device 10 is responsible for stably conveying the magnetic device to be tested to the next station of the production line. The laser coding scanner 20 is located on the conveying path of the loading device 10. When the product 1 passes by, the laser coding scanner 20 will code the product 1, generate a unique product 1 identification code, and read this identification code by scanning the code for subsequent tracking and management. The testing device 30 includes two parts: a withstand voltage test mechanism 31 and a disc comprehensive testing mechanism 32. The withstand voltage test mechanism 31 is used to detect the withstand voltage performance of the product 1 to ensure the safety and reliability of the product 1 under high pressure. The disc comprehensive testing mechanism 32 tests other comprehensive properties of the product 1, such as impedance, copper resistance, etc. The handling device 40 is responsible for taking out the product 1 to be tested for which the identification code has been generated from the loading position of the loading device 10, and transporting it to the testing device 30 for testing. After the test is completed, the handling device 40 will transport the product 1 to the visual inspection system 50. The visual inspection system 50 is provided with an inspection position for receiving the product 1 conveyed by the conveying device 40 from the testing device 30. The visual inspection system 50 performs visual inspection on the product 1 through a camera and image processing software to identify defects or abnormalities on the surface of the product 1. The unloading device 60 is located next to the visual inspection system 50, and includes a good product unloading mechanism 61 and a bad product receiving mechanism 62. The good product unloading mechanism 61 is used to receive products 1 that pass the visual inspection and convey them to the packaging or storage area. The bad product receiving mechanism 62 receives products 1 that fail the inspection for rework or scrapping.

[0040] The loading device 10 is connected to the laser coding scanner 20 to ensure that the product 1 is coded and scanned during the conveying process. The laser coding scanner 20 is connected to the testing device 30 to ensure that the coded product 1 can smoothly enter the testing phase. The testing device 30 is connected to the transport device 40, which is responsible for moving the product 1 from the testing device 30 to the visual inspection system 50. The visual inspection system 50 is connected to the unloading device 60, which transmits the inspection results to the unloading device 60 so as to correctly classify the product 1.

[0041] The entire test process is automated, reducing manual intervention and improving production efficiency and test accuracy. Through laser coding and scanning, each product 1 can be tracked for quality control and after-sales service. Through voltage resistance testing and comprehensive performance testing, it is ensured that product 1 meets quality standards and improves the reliability of product 1. The visual inspection system 50 can accurately identify unqualified products 1, reduce the flow of defective products into the market, and reduce corporate losses. The automated handling device 40 and unloading device 60 reduce the waiting time of product 1 during the test and speed up the production process. All devices can be used alone or connected to other production lines to form an automated production line, which is convenient for users to debug, maintain, repair and replace products 1, and change the production process according to the needs of users at different times, with strong adaptability.

[0042] In this example, the feeding device 10 includes a conveying bracket 11, a driving mechanism 12, a conveying structure 13 and a plurality of fixed fixtures 14; the driving mechanism 12 is mounted on the conveying bracket 11 and connected to the conveying structure 13 to transmit power to the conveying structure 13; the conveying structure 13 is arranged on the conveying bracket 11, and the conveying structure 13 has a conveying surface, and the conveying surfaces are connected end to end to form a complete return shape; each fixed fixture 14 is arranged at intervals and fixed on the conveying surface. Specifically, the feeding device 10 is the first link of the entire automatic line, responsible for conveying the magnetic device to be tested from the storage area to the production line. The conveying bracket 11 is the main structure of the feeding device 10, which supports the entire conveying system and provides an installation platform for other components. The driving mechanism 12 is the power source of the feeding device 10, usually including components such as a motor and a reducer, which is responsible for providing power to move the conveying structure 13. The conveying structure 13 is the part that directly contacts the magnetic device, and it conveys the product 1 from one position to another through movement. The conveying structure 13 is connected to the driving mechanism 12, receives power and starts to move. The conveying structure 13 has a conveying surface, which is connected end to end to form a complete loop path, ensuring that the product 1 can move continuously on the conveying surface. The fixed fixture 14 is a device for stabilizing and positioning the magnetic device. They are arranged at intervals and fixedly on the conveying surface to ensure that the product 1 maintains the correct position and direction during the conveying process. The connection design between the drive mechanism 12 and the conveying structure 13 can efficiently transmit power to the conveying structure 13 and reduce energy loss. The loop path formed by the conveying surface allows the product 1 to move continuously on the conveying line, improving the continuity and efficiency of the production line. The interval setting of the fixed fixture 14 ensures the precise positioning of the magnetic device during the conveying process, reducing the test error or damage to the product 1 caused by inaccurate positioning. The fixed fixture 14 can be adjusted according to different sizes and shapes of the product 1, improving the adaptability and flexibility of the feeding device 10. Due to the modular design of each component, the maintenance and repair of the feeding device 10 becomes simpler and the maintenance cost is reduced. The use of the fixed fixture 14 can prevent the product 1 from sliding or falling off during the conveying process, improving the safety of the operation.

[0043] In this example, a sliding hole 111 extending along the length direction of the conveying bracket 11 is provided at one end of the conveying bracket 11 away from the driving mechanism 12, and both ends of the roller 131 of the conveying structure 13 are arranged in the sliding hole 111, and the horizontal position of the roller 131 can be adjusted through the sliding hole 111. Specifically, a sliding hole 111 extending along the length direction of the conveying bracket 11 is provided at one end of the conveying bracket 11 away from the driving mechanism 12, and these sliding holes 111 are used to install and adjust the roller 131 in the conveying structure 13. The roller 131 in the conveying structure 13 is a key component of the belt conveying system, which supports and drives the movement of the belt. Both ends of the roller 131 are arranged in the sliding hole 111, and its horizontal position can be adjusted through the sliding hole 111. By moving the roller 131 in the sliding hole 111, the tension of the belt and the alignment of the roller 131 can be adjusted to ensure the smooth operation of the belt and reduce wear. The conveying bracket 11 is connected to the sliding hole 111, and the sliding hole 111 extends along the length direction of the conveying bracket 11 and is used to install the roller 131. Both ends of the roller 131 are arranged in the slide hole 111, and are connected to the conveying bracket 11 through the slide hole 111, and its position can be adjusted along the slide hole 111. The design of the slide hole 111 allows the position of the roller 131 to be flexibly adjusted to accommodate products 1 of different widths or to adjust the belt tension. The adjustability of the roller 131 makes it easier to maintain and replace the belt because the roller 131 can be easily removed from the slide hole 111. By adjusting the position of the roller 131, it is possible to ensure good contact between the belt and the roller 131, reducing unnecessary wear of the belt. Correctly adjusting the position of the roller 131 helps maintain the stability and parallelism of the belt and reduce the problem of belt deviation.

[0044] In this example, the feeding device 10 also includes a product direction detection mechanism 15, which is arranged on the conveying bracket 11 and located at the output end of the conveying structure 13, and is used to detect whether the product 1 is installed upside down in the fixed fixture 14. Specifically, the product direction detection mechanism 15 is connected to the conveying bracket 11 and installed at the output end of the conveying structure 13. The detection mechanism is connected to the control system and transmits the detection result to the control system for subsequent processing. By detecting whether the product 1 is installed upside down, test failure or damage to the product 1 caused by wrong direction can be prevented. Ensure that all products 1 are tested in the correct direction, thereby improving the accuracy and reliability of the test results. Timely detection and correction of products 1 with wrong directions reduces rework or waste caused by wrong directions and improves the overall efficiency of the production line. Automated direction detection reduces the need for manual inspection, reduces labor costs and the possibility of human errors. By ensuring the correct installation direction of the product 1, the quality of the final product 1 can be improved and performance problems caused by wrong directions can be reduced.

[0045] In this example, the product direction detection mechanism 15 includes a mounting bracket 151 and a CCD camera 152. The mounting bracket 151 is mounted on the conveying bracket 11, and the CCD camera 152 is mounted on the mounting bracket 151. The CCD camera 152 is located directly above the conveying structure 13 and is used to take photos to detect the product 1 to be tested that passes directly below the CCD camera 152. Specifically, the CCD camera 152 is mounted on the mounting bracket 151 and is located directly above the conveying structure 13. It detects the product 1 to be tested that passes directly below it by taking photos and identifies whether the product 1 is installed upside down. Working principle of the CCD camera 152: The CCD camera 152 converts the incident light signal into a charge output through the photoelectric effect, and then completes the image capture through the generation, storage, transmission, detection and output of the signal charge. The image data of the CCD camera 152 is a data set of each pixel constituting the CCD, and each pixel can be represented by a numerical value within a certain range, so as to obtain the intensity and distribution of light on the image. The mounting bracket 151 is connected to the conveying bracket 11 to provide an installation position for the CCD camera 152. The CCD camera 152 is connected to the mounting bracket 151 and is located directly above the conveying structure 13 so as to detect the passing product 1 to be tested. The CCD camera 152 transmits the detected image information to the control system via a data line or a wireless signal for further analysis and processing. Through the photo detection of the CCD camera 152, the correct installation direction of the product 1 to be tested in the fixed fixture 14 can be ensured to avoid test errors or damage to the product 1 caused by reverse installation. The automated detection of the product direction detection mechanism 15 improves the automation level of the production line and reduces the need for manual detection. The CCD camera 152 has high resolution and accurate image capture capabilities, which can accurately detect the direction of the product 1 and improve the detection accuracy. Automated product 1 direction detection can speed up the detection speed, reduce production downtime, and improve overall production efficiency. Reducing manual detection can reduce labor costs, while reducing waste and rework caused by reverse installation, further reducing production costs. Through accurate direction detection, the quality of the product 1 can be improved, performance problems caused by reverse installation can be reduced, and quality control can be improved.

[0046] In this example, the feeding device 10 also includes an in-place sensor 16 electrically connected to the drive mechanism 12, and the in-place sensor 16 is arranged on the conveying bracket 11 and located at the conveying end of the conveying structure 13. Specifically, the in-place sensor 16 is a detection mechanism for confirming whether the product 1 has moved to a predetermined position. In the feeding device 10, the in-place sensor 16 is electrically connected to the drive mechanism 12 to ensure that the sensor can send a signal when the product 1 reaches the conveying end of the conveying structure 13. The in-place sensor 16 is arranged on the conveying bracket 11 and located at the conveying end of the conveying structure 13, which means that the sensor is located at the end of the conveying line and is used to detect whether the product 1 has reached the end of the conveying line. When the product 1 arrives at the conveying end, the in-place sensor 16 detects the presence of the product 1 and sends a signal to the control system. This signal indicates that the product 1 has arrived at the specified position and can proceed to the next operation. The in-place sensor 16 is electrically connected to the drive mechanism 12 to ensure that the signal detected by the sensor can be received and responded to by the drive mechanism 12. The sensor is arranged on the conveying bracket 11, adjacent to the conveying end of the conveying structure 13, so as to detect when the product 1 arrives at the conveying end. The in-place sensor 16 provides precise position control, ensuring that the product 1 can be accurately tracked at each stage of the conveying process. By ensuring that the product 1 arrives at the intended location correctly, the in-place sensor 16 helps to improve the efficiency of the production line and reduce delays caused by position errors.

[0047] In this example, the laser coding scanner 20 includes a coder 21 and a code scanning mechanism 22, which are respectively located on the left and right sides of the feeding device 10. The coder 21 is used to generate laser to code the product 1, and the code scanning mechanism 22 is used to scan and record the generated identification code. Specifically, the coder 21 uses laser technology to engrave the identification code on the surface of the product 1. The laser beam focuses on the surface of the product 1 at an extremely high energy density, and removes the surface material by burning or etching to form a permanent mark. The code scanning mechanism 22 usually includes a CCD camera 152 or a similar image capture device, which is used to scan the identification code generated by the coder 21 and convert it into digital information for recording and tracking. The CCD camera 152 captures the image through photoelectric conversion technology, converts the identification code into a digital signal, and then decodes it to obtain the product 1 information. The coder 21 and the code scanning mechanism 22 are respectively located on the left and right sides of the feeding device 10, and they work together through the setting of physical positions and the connection of the control system. The in-place sensor 16 is electrically connected to the drive mechanism 12 to ensure that the coding and scanning process can be accurately performed when the product 1 reaches the conveying end of the conveying structure 13. The in-place sensor 16 is arranged on the conveying bracket 11, located at the conveying end of the conveying structure 13, and coordinated with the position of the coder 21 and the code scanning mechanism 22 to ensure that the product 1 is coded and scanned in the correct position. The laser coding scanner 20 can quickly code and scan the product 1, improving the efficiency of the production line. Laser coding provides high-precision markings, and the code scanning mechanism 22 can accurately read these marks to ensure the accuracy of the data. The marks produced by laser coding are permanent and not easy to wear or fade, which helps to track and manage the product 1 for a long time. Automated coding and scanning reduce errors in manual data entry and improve the reliability of data. By assigning a unique identification code to each product 1, the flow direction of the product 1 and the storage information can be tracked more effectively. The laser coding scanner 20 can adapt to different production line layouts and product 1 types, with good flexibility and adaptability. Although the initial investment may be high, in the long run, the automated coding and scanning system can reduce labor costs, improve production efficiency, and thus reduce overall costs. Through accurate coding and scanning, it can ensure that only qualified products 1 can enter the market, improving the quality and brand image of products 1.

[0049] Specifically, the withstand voltage test mechanism 31 is mainly used to test the withstand voltage performance of the product 1 to ensure the insulation performance and safety of the product 1 under high voltage conditions. The probe withstand voltage assembly 311 is the core part of the withstand voltage test mechanism 31. It detects whether the product 1 can maintain insulation performance under the specified withstand voltage by applying high voltage. The withstand voltage test fixture 312 is used to fix the product 1 to be tested so that it can be stably placed on the test equipment. The fixture is provided with a fixed cavity 315 for accommodating and fixing the product 1. The linear drive structure 313 is responsible for driving the withstand voltage test fixture 312 to move along the base 314, so that the fixture can be close to or away from the probe withstand voltage assembly 311 for withstand voltage testing. The base 314 is the supporting structure of the withstand voltage test mechanism 31. The withstand voltage test fixture 312 is installed on the base 314 by a sliding connection, and the linear drive structure 313 drives the withstand voltage test fixture 312 to move. The probe withstand voltage assembly 311 is fixed at one end of the base 314, opposite to the position of the withstand voltage test fixture 312, and the two cooperate to perform withstand voltage testing. The linear drive structure 313 is connected to the withstand voltage test fixture 312. By driving the movement of the fixture to adjust the distance between the fixture and the probe withstand voltage component 311, the withstand voltage test mechanism 31 can effectively test the withstand voltage performance of the product 1, ensure the safety of the product 1 under high voltage conditions, and prevent electrical failures and safety accidents. The linear drive structure 313 can accurately control the position of the withstand voltage test fixture 312 to ensure that the distance between the probe withstand voltage component 311 and the product 1 to be tested is appropriate, thereby improving the test accuracy. Through the automated linear drive structure 313, the withstand voltage test process is more efficient, reducing the time and labor intensity of manual operation. The sliding connection design of the withstand voltage test fixture 312 allows the test mechanism to adapt to products 1 of different sizes and shapes, improving the flexibility and applicability of the equipment. Due to the modular design of the withstand voltage test mechanism 31, each component is easy to disassemble and maintain, reducing maintenance costs and complexity.

[0050] In this example, the withstand voltage test mechanism 31 also includes a detection sensor 316 electrically connected to the linear moving structure 53 and the probe withstand voltage assembly 311. The detection sensor 316 is arranged beside the withstand voltage test fixture 312 and is used to detect whether the withstand voltage test fixture 312 is installed with a product 1. Specifically, the detection sensor 316 is electrically connected to the linear moving structure 53 and the probe withstand voltage assembly 311 and is arranged beside the withstand voltage test fixture 312. Its function is to detect whether the withstand voltage test fixture 312 has been installed with the product 1 to be tested. When the withstand voltage test fixture 312 moves to the test position, the detection sensor 316 senses whether there is a product 1 on the fixture through an electrical connection. If there is no product 1 on the fixture, the detection sensor 316 will send a signal to prevent meaningless or potentially damaging testing of the equipment. Ensure the accuracy and safety of the test.

The impedance test assembly 323 is responsible for testing the resistance characteristics of the product 1 to ensure that the product 1 meets the predetermined resistance specifications. The copper resistance test assembly 324 is used to measure the resistance of the copper wire part in the product 1 to evaluate the quality and performance of the copper wire. When the disc assembly 321 rotates, the product 1 to be tested fixed on the test position will pass through the superposition test assembly 322, the impedance test assembly 323 and the copper resistance test assembly 324 in turn for corresponding tests. The disc assembly 321 is a central structure and can be rotatably set on the base 314 or the bracket. The stacking test assembly 322, the impedance test assembly 323 and the copper resistance test assembly 324 are arranged around the disc assembly 321 so that they can contact the test positions on the disc assembly 321 in turn. Each test assembly corresponds to the test position of the disc assembly 321 to ensure that the product 1 on each test position can receive the necessary test. The disc integrated test mechanism 32 can continuously and automatically test multiple products 1, greatly improving the test efficiency. A variety of test assemblies are integrated, and multiple tests can be completed on one device, reducing the need for other test equipment. The automated testing process reduces human operating errors and improves the accuracy and repeatability of test results.

Through precise testing, unqualified products 1 can be discovered in a timely manner, improving the quality and reliability of products 1. The modular design makes each test assembly easy to disassemble and maintain, reducing maintenance costs.

[0054] Specifically, the gantry 41 is the main structure of the handling device 40, providing support and guidance for other components. The horizontal moving mechanism 42 is arranged on the gantry 41, and is responsible for driving the vertical moving mechanism 43 to move horizontally along the length direction of the gantry 41. The vertical moving mechanism 43 is arranged at the moving end of the horizontal moving mechanism 42, and is responsible for driving the lifting seat 44 to move vertically along the height direction of the gantry 41. The lifting seat 44 is connected to the moving end of the vertical moving mechanism 43, and can move up and down along the vertical moving mechanism 43 to adjust the height of the manipulator. The manipulator is installed on the lifting seat 44 for picking up and placing the product 1. The manipulator can be pneumatic, electric or mechanical, and can grab and release the product 1 as needed. The horizontal moving mechanism 42 is fixed on the gantry 41, and the vertical moving mechanism 43 is installed on the moving end of the horizontal moving mechanism 42, and the two are connected by a mechanical connection or a power transmission system. The lifting seat 44 is connected to the moving end of the vertical moving mechanism 43, and can move up and down along the vertical moving mechanism 43. The picking robot 45 is mounted on the lifting seat 44 and fixed by a mechanical connection or a quick-change system. It can move precisely in the horizontal and vertical directions to pick up the product 1. The handling device 40 can quickly and accurately transport the product 1, thereby improving the efficiency of the production line. The handling device 40 can adapt to products 1 of different sizes and weights by simply adjusting the gripping method of the robot and the height of the lifting seat 44. Automated handling reduces the need for manual handling, labor intensity and the risk of work-related injuries. Precise horizontal and vertical movement control ensures accurate placement of the product 1, reducing damage and errors. The modular design makes it easy to disassemble and maintain each component, reducing maintenance costs.

[0055] In this example, the manipulator includes a rotating pickup mechanism 451 and two fixed pickup mechanisms 452, which are evenly spaced in sequence on the lifting seat 44, wherein the rotating pickup mechanism 451 is arranged close to the next station. Specifically, the rotating pickup mechanism 451 is a movable component in the manipulator, which can rotate around a certain center point to pick up the product 1 from different positions and move it to the next station. The lifting seat 44 is the supporting structure of the manipulator, which can move up and down along the vertical moving mechanism 43 to adjust the height of the manipulator so that it can reach different working heights. The rotating pickup mechanism 451 and the two fixed pickup mechanisms 452 are all installed on the lifting seat 44, and they are evenly spaced to ensure that each pickup mechanism can cover its respective working area when the manipulator moves to different positions. The rotating pickup mechanism 451 is usually designed with a rotating joint, allowing it to rotate within a certain angle range to facilitate approaching and picking up the product 1. The fixed picking mechanism 452 is directly fixed on the lifting seat 44 and has no rotation function, but can move up and down to accommodate products 1 of different heights. The rotating picking mechanism 451 provides additional degrees of freedom, allowing the manipulator to pick up products 1 from different angles and positions, thereby improving the flexibility of the handling device 40. The combination of the fixed picking mechanism 452 and the rotating picking mechanism 451 allows the manipulator to handle multiple products 1 at the same time, thereby improving the handling efficiency of the production line. The rotating picking mechanism 451 is set close to the next workstation to ensure that the product 1 is accurately placed at the next workstation, reducing positioning errors. The design of the manipulator can adapt to products 1 of different sizes and shapes, and only the position and angle of the picking mechanism need to be adjusted.

The 3D line scan camera 51 is a key component of the visual inspection system 50, and acquires the three-dimensional information of the product 1 placed on the scanning position 52 by emitting laser lines and capturing the reflected light. The scanning position 52 is the area where the product 1 is placed, and is arranged opposite to the mobile structure 53, and is used to support and fix the product 1 to be inspected. The mobile structure 53 carries the 3D line scan camera 51 and moves along a preset path to ensure that the laser line can cover and scan the entire surface of the product 1. The 3D line scan camera 51 is arranged at the mobile end of the mobile structure 53.
