The disc comprehensive testing mechanism 32 tests other comprehensive performances of the product 1, such as resistance and copper resistance performance. The conveying device 40 is responsible for taking the product 1 to be tested with the generated identification code from the feeding position of the feeding device 10, and conveying it to the testing device 30 for testing. After testing is completed, the conveying device 40 will convey the product 1 to the vision detection system 50. The vision detection system 50 is provided with a detection position for receiving the product 1 conveyed from the testing device 30 by the conveying device 40. The vision detection system 50 detects the product 1 through a camera and image processing software to identify defects or abnormalities on the surface of the product 1. The discharging device 60 is located beside the vision detection system 50, and includes a good product discharging mechanism 61 and a defective product collecting mechanism 62. The good product discharging mechanism 61 is used to receive the product 1 that passes the vision detection, and convey them to a packaging or storage area.

The vision detection system 50 is connected with the discharging device 60, and the vision detection system 50 transmits the detection result to the discharging device 60 to correctly classify the product 1.

[0041] The whole testing process is automated, reducing manual intervention and improving production efficiency and testing accuracy. Through laser coding and scanning, each product 1 can be tracked, facilitating quality control and after-sales service. Through voltage resistance testing and comprehensive performance testing, it is ensured that the product 1 meets the quality standards and improves the reliability of the product 1.

All devices can be used alone or connected with other production lines to form an automatic production line, facilitating user debugging, maintenance, repair and replacement of products 1, changing the production process according to the user's needs at different periods, and having strong adaptability.

[0042] In this example, the feeding device 10 includes a conveying support 11, a driving mechanism 12, a conveying structure 13, and a plurality of fixing jigs 14. The driving mechanism 12 is installed on the conveying support 11 and connected with the conveying structure 13 to transmit power to the conveying structure 13. The conveying structure 13 is arranged on the conveying support 11 and has a conveying surface that is connected end to end to form a complete loop. The fixing jigs 14 are arranged on the conveying surface in a spaced and fixed manner. Specifically, the feeding device 10 is the first link of the entire automatic line and is responsible for conveying the magnetic devices to be tested from the storage area to the production line. The conveying support 11 is the main structure of the feeding device 10, which supports the entire conveying system and provides a mounting platform for other components. The driving mechanism 12 is the power source of the feeding device 10, which usually includes components such as motors and reducers, and is responsible for providing power to make the conveying structure 13 move. The conveying structure 13 is the part that directly contacts the magnetic devices, which moves the products 1 from one location to another. The conveying structure 13 is connected with the driving mechanism 12 to receive power and start moving. The conveying structure 13 has a conveying surface that is connected end to end to form a complete loop path, ensuring that the products 1 can continuously move on the conveying surface. The fixing jigs 14 are devices for stabilizing and positioning the magnetic devices, which are arranged on the conveying surface in a spaced and fixed manner to ensure that the products 1 maintain the correct position and direction during the conveying process. The connection design of the driving mechanism 12 and the conveying structure 13 can efficiently transmit power to the conveying structure 13, reducing energy loss. The loop path formed by the conveying surface allows the products 1 to continuously move on the conveying line, improving the continuity and efficiency of the production line. The spaced arrangement of the fixing jigs 14 ensures accurate positioning of the magnetic devices during the conveying process, reducing testing errors or product 1 damage caused by inaccurate positioning. The fixing jigs 14 can be adjusted according to different product 1 sizes and shapes, 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 become more convenient, reducing maintenance costs.

[0043] In this example, the conveying bracket 11 is provided with slide holes 111 extending along the length of the conveying bracket 11 at the end away from the driving mechanism 12, and the rollers 131 of the conveying structure 13 are arranged in the slide holes 111 and can adjust the horizontal position of the rollers 131 through the slide holes 111. Specifically, the conveying bracket 11 is provided with slide holes 111 extending along the length of the conveying bracket 11 at the end away from the driving mechanism 12, and these slide holes 111 are used to install and adjust the rollers 131 in the conveying structure 13. The rollers 131 in the conveying structure 13 are key components of the belt conveying system, which support and drive the movement of the belt. The two ends of the rollers 131 are arranged in the slide holes 111, and their horizontal position can be adjusted through the slide holes 111. By moving the rollers 131 in the slide holes 111, the tension of the belt and the alignment of the rollers 131 can be adjusted to ensure smooth operation of the belt and reduce wear and tear. The conveying bracket 11 is connected to the slide holes 111, which extend along the length of the conveying bracket 11 and are used to install the rollers 131. The two ends of the rollers 131 are arranged in the slide holes 111 and connected to the conveying bracket 11 through the slide holes 111, and their position can be adjusted along the slide holes 111. The design of the slide holes 111 allows flexible adjustment of the position of the rollers 131 to accommodate products 1 of different widths or adjust the tension of the belt. The adjustability of the rollers 131 makes it easier to maintain and replace the belt, as the rollers 131 can be easily removed from the slide holes 111. By adjusting the position of the rollers 131, good contact between the belt and the rollers 131 can be ensured, reducing unnecessary wear and tear of the belt. Proper adjustment of the position of the rollers 131 helps maintain the stability and parallelism of the belt, reducing the problem of belt deviation.

[0044] In this example, the feeding device 10 also includes a product direction detection mechanism 15 arranged on the conveying bracket 11 and located at the output end of the conveying structure 13, which is used to detect whether the product 1 is installed in reverse in the fixing jig 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 results to the control system for subsequent processing. By detecting whether the product 1 is installed in reverse, it can prevent test failure or product 1 damage caused by incorrect orientation. Ensuring that all products 1 are tested in the correct orientation improves the accuracy and reliability of test results. Timely detection and correction of products 1 with incorrect orientation reduces rework or scrap caused by incorrect orientation, improving the overall efficiency of the production line. Automated orientation detection reduces the need for manual inspection, reducing labor costs and the likelihood of human error. 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 incorrect orientation can be reduced.

[0045] In this example, the product direction detection mechanism 15 includes a mounting bracket 151 mounted on the conveying bracket 11 and a CCD camera 152 mounted on the mounting bracket 151, which is located directly above the conveying structure 13 for photographing detection of the product 1 passing directly below the CCD camera 152. Specifically, the CCD camera 152 is mounted on the mounting bracket 151 and located directly above the conveying structure 13. It detects the product 1 passing directly below it by photographing and identifies whether the product 1 is installed upside down. The working principle of the CCD camera 152: the CCD camera 152 converts the incident light signal into charge output through the photoelectric effect, and then completes the capture of the image through the generation, storage, transmission and detection and output of signal charge. The image data of the CCD camera 152 is a collection of data of each pixel constituting the CCD, each pixel can be represented by a certain range of values, so as to obtain the intensity and distribution of light on the image. The mounting bracket 151 is connected with the conveying bracket 11 to provide a mounting position for the CCD camera 152. The CCD camera 152 is connected with the mounting bracket 151 and located directly above the conveying structure 13 to detect the product 1 passing through. The CCD camera 152 transmits the detected image information to the control system through data line or wireless signal for further analysis and processing. Through the photographing detection of the CCD camera 152, the correct installation direction of the product 1 in the fixture 14 can be ensured, and the test error or damage of the product 1 caused by installation upside down can be avoided. The automatic detection of the product direction detection mechanism 15 improves the automation degree of the production line and reduces the need for manual detection. The CCD camera 152 has high resolution and accurate image capture capability, which can accurately detect the direction of the product 1 and improve the detection accuracy. The automatic detection of the direction of the product 1 can speed up the detection speed, reduce the production stagnation time and improve the overall production efficiency. Reducing manual detection can reduce labor costs, while reducing waste and rework caused by installation upside down, further reducing production costs. Through accurate direction detection, the quality of the product 1 can be improved, the performance problems caused by installation upside down can be reduced, and the quality control can be improved.

[0046] In the present example, the feeding device 10 further comprises a presence sensor 16 electrically connected to the drive mechanism 12, the presence sensor 16 being arranged on the conveying support 11 and located at the conveying end of the conveying structure 13. In particular, the presence sensor 16 is a detection mechanism for confirming whether the product 1 has been moved to a predetermined position. In the feeding device 10, the presence sensor 16 is electrically connected to the drive mechanism 12, ensuring that the sensor can send a signal when the product 1 reaches the conveying end of the conveying structure 13. The presence sensor 16 is arranged on the conveying support 11 and located at the conveying end of the conveying structure 13, meaning that the sensor is located at the end of the conveying line for detecting whether the product 1 has reached the end of the conveying line. When the product 1 reaches the conveying end, the presence 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 reached the designated position and the next operation can be performed. The presence sensor 16 is electrically connected to the drive mechanism 12, ensuring 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 support 11 adjacent to the conveying end of the conveying structure 13 in order to detect when the product 1 reaches the conveying end. The presence sensor 16 provides precise position control, ensuring that the product 1 can be accurately tracked at every stage of the conveying process. By ensuring that the product 1 correctly reaches the predetermined position, the presence sensor 16 helps to improve the efficiency of the production line and reduce delays caused by positional errors.

[0047] In this example, the laser coding and scanning device 20 includes a coder 21 and a scanning mechanism 22, which are located on the left and right sides of the feeding device 10, respectively. The coder 21 is used to generate laser codes on the product 1, and the scanning mechanism 22 is used to scan and record the generated identification codes. Specifically, the coder 21 uses laser technology to engrave identification codes on the surface of the product 1. The laser beam is focused on the surface of the product 1 at a very high energy density, removing the surface layer of material through burning or etching, forming permanent marks. The scanning mechanism 22 usually contains a CCD camera 152 or similar image capture device, which is used to scan the identification codes generated by the coder 21 and convert them into digital information for recording and tracking. The CCD camera 152 captures images through photoelectric conversion technology, converts the identification codes into digital signals, and then decodes them to obtain the information of the product 1. The coder 21 and the scanning mechanism 22 are located on the left and right sides of the feeding device 10, respectively, and they work together through the physical position setting and the connection of the control system. The in-place sensor 16 is electrically connected to the driving 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 set on the conveying bracket 11 and located at the conveying end of the conveying structure 13, which is coordinated with the positions of the coder 21 and the scanning mechanism 22 to ensure that the product 1 is coded and scanned at the correct position. The laser coding and scanning device 20 can quickly code and scan the product 1, improving the efficiency of the production line. Laser coding provides high-precision marks, and the scanning mechanism 22 can accurately read these marks to ensure data accuracy. The marks generated by laser coding are permanent and not easy to wear or fade, which helps long-term tracking and management of the product 1. Automated coding and scanning reduce human error in data input, improving data reliability. By assigning a unique identification code to each product 1, the flow and storage information of the product 1 can be more effectively tracked. The laser coding and scanning device 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 precise coding and scanning, only qualified products 1 can enter the market, improving the quality and brand image of the product 1.

The base 314 is the support structure of the voltage withstand test mechanism 31. The voltage withstand test jig 312 is installed on the base 314 by sliding connection, and the linear drive structure 313 drives the voltage withstand test jig 312 to move. The probe voltage withstand assembly 311 is fixed at one end of the base 314, opposite to the position of the voltage withstand test jig 312, and the two cooperate to perform voltage withstand testing. The linear drive structure 313 is connected to the voltage withstand test jig 312, and adjusts the distance between the jig and the probe voltage withstand assembly 311 by driving the movement of the jig. The voltage withstand test mechanism 31 can effectively test the voltage withstand performance of the product 1, ensure the safety of the product 1 under high voltage conditions, and prevent electrical faults and safety accidents.

Due to the modular design of the voltage withstand test mechanism 31, each component is easy to disassemble and maintain, reducing maintenance cost and complexity.

[0050] In the present example, the voltage resistance test mechanism 31 further comprises a detection sensor 316 electrically connected with the linear drive structure 313 and the probe voltage resistance assembly 311, which is arranged beside the voltage resistance test fixture 312 and used to detect whether the voltage resistance test fixture 312 is installed with the product 1. Specifically, the detection sensor 316 is electrically connected with the linear drive structure 313 and the probe voltage resistance assembly 311 and arranged beside the voltage resistance test fixture 312. Its function is to detect whether the voltage resistance test fixture 312 has installed the product 1 to be tested. When the voltage resistance test fixture 312 moves to the test position, the detection sensor 316 senses whether there is the product 1 on the fixture through the electrical connection. If there is no product 1 on the fixture, the detection sensor 316 will send a signal to prevent the test from being meaningless or possibly damaging the equipment. The accuracy and safety of the test are ensured.

[0051] In the present example, the disc comprehensive test mechanism 32 comprises a disc assembly 321, a superposition test assembly 322, a resistance test assembly 323 and a copper resistance test assembly 324; the disc assembly 321 is rotatably arranged, the disc assembly 321 is provided with test sites for fixing the product 1, and the superposition test assembly 322, the resistance test assembly 323 and the copper resistance test assembly 324 are arranged around the disc assembly 321.

[0052] Specifically, the disc comprehensive testing mechanism 32 is used for multiple tests on the magnetic device, including superposition test, resistance test and copper resistance test. The disc assembly 321 is the core part of the testing mechanism and can be rotatably arranged. It is provided with multiple test sites for fixing the products 1 to be tested.

The resistance test assembly 323 is responsible for testing the resistance characteristics of the products 1 to ensure that the products 1 meet the predetermined resistance specifications. The copper resistance test assembly 324 is used for measuring the resistance of the copper wire part of the products 1 to evaluate the quality and performance of the copper wire. When the disc assembly 321 rotates, the products 1 to be tested fixed on the test sites will pass through the superposition test assembly 322, the resistance test assembly 323 and the copper resistance test assembly 324 in turn for corresponding tests. The disc assembly 321 as the central structure is rotatably arranged on the base 314 or the support. The superposition test assembly 322, the resistance test assembly 323 and the copper resistance test assembly 324 are arranged around the disc assembly 321 so that they can contact the test sites on the disc assembly 321 in turn. Each test assembly corresponds to a test site on the disc assembly 321 to ensure that the products 1 on each test site can undergo necessary tests. The disc comprehensive testing mechanism 32 can continuously and automatically test multiple products 1, greatly improving the testing efficiency. The integration of multiple test assemblies can complete multiple tests on one device, reducing the need for other test equipment. The automated testing process reduces human operation errors and improves the accuracy and repeatability of test results. The design of the disc assembly 321 allows quick replacement or adjustment of the test sites to accommodate different sizes and types of products 1. Automated testing reduces the need for manual operation, reducing labor costs and labor intensity. Through accurate testing, unqualified products 1 can be found in time, improving the quality and reliability of the products 1. The modular design makes it easy to disassemble and maintain each test assembly, 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 movement mechanism 42 is arranged on the gantry 41, responsible for driving the vertical movement mechanism 43 horizontally along the length of the gantry 41. The vertical movement mechanism 43 is arranged on the moving end of the horizontal movement mechanism 42, responsible for driving the lifting seat 44 vertically along the height of the gantry 41. The lifting seat 44 is connected to the moving end of the vertical movement mechanism 43 and can move up and down along the vertical movement mechanism 43 to adjust the height of the robot arm. The robot arm is installed on the lifting seat 44 and is used to pick up and place the product 1. The robot arm can be pneumatic, electric or mechanical, and can grasp and release the product 1 as needed. The horizontal movement mechanism 42 is fixed on the gantry 41, and the vertical movement mechanism 43 is installed on the moving end of the horizontal movement mechanism 42, connected through mechanical connection or power transmission system. The lifting seat 44 is connected to the moving end of the vertical movement mechanism 43 and can move up and down along the vertical movement mechanism 43. The picking robot arm 45 is installed on the lifting seat 44 and is fixed through mechanical connection or quick change system, which can move accurately in horizontal and vertical directions to pick up the product 1. The handling device 40 can quickly and accurately handle the product 1, improving the efficiency of the production line. The handling device 40 can adapt to products 1 of different sizes and weights, only need to adjust the grasping method of the robot arm and the height of the lifting seat 44. Automated handling reduces the need for manual handling, reducing labor intensity and the risk of injury. Precise horizontal and vertical movement control ensures accurate placement of the product 1, reducing damage and errors. Modular design makes it easy to disassemble and maintain individual components, reducing maintenance costs. The automated handling device 40 reduces product 1 handling time and improves production efficiency.

[0055] In this example, the robot includes a rotating pick-up mechanism 451 and two fixed pick-up mechanisms 452, which are evenly spaced on the lifting seat 44 in sequence, where the rotating pick-up mechanism 451 is located near the next work station. Specifically, the rotating pick-up mechanism 451 is a movable part of the robot, which can rotate around a certain center point to pick up products 1 from different positions and move them to the next work station. The lifting seat 44 is the supporting structure of the robot, which can move up and down along the vertical movement mechanism 43 to adjust the height of the robot so that it can reach different working heights. The rotating pick-up mechanism 451 and the two fixed pick-up mechanisms 452 are installed on the lifting seat 44, and they are evenly spaced to ensure that each pick-up mechanism can cover its own working area when the robot moves to different positions. The rotating pick-up mechanism 451 is usually designed with a rotating joint that allows it to rotate within a certain angle range to facilitate access and pick up products 1. The fixed pick-up mechanism 452 is directly fixed on the lifting seat 44 and has no rotating function, but can move up and down to adapt to products 1 of different heights. The rotating pick-up mechanism 451 provides additional degrees of freedom, allowing the robot to pick up products 1 from different angles and positions, improving the flexibility of the conveying device 40. The combination of the fixed pick-up mechanism 452 and the rotating pick-up mechanism 451 allows the robot to handle multiple products 1 at the same time, improving the conveying efficiency of the production line. The rotating pick-up mechanism 451 is located near the next work station, which can ensure that the products 1 are accurately placed into the next work station, reducing positioning errors. The design of the robot can adapt to products 1 of different sizes and shapes, only need to adjust the position and angle of the pick-up mechanism.

[0056] In this example, the visual inspection system 50 includes a 3D line scan camera 51, a scanning station 52, and a moving structure 53. The scanning station 52 is positioned opposite the moving structure 53. The 3D line scan camera 51 is positioned at the moving end of the moving structure 53 and is used to detect the coplanarity of the product 1 placed on the scanning station 52. Specifically, when the product 1 is in a certain posture during scanning, it is ensured that the four detection protrusions are on the same focal line. The 3D line scan camera 51 is a key component of the visual inspection system 50. It emits a laser line and captures the reflected light to obtain the three-dimensional information of the product 1 placed on the scanning station 52. The scanning station 52 is the area where the product 1 is placed and is positioned opposite the moving structure 53. It is used to support and fix the product 1 to be detected. The moving structure 53 carries the 3D line scan camera 51 to move along a predetermined path, ensuring that the laser line can cover and scan the entire surface of the product 1. The 3D line scan camera 51 is positioned at the moving end of the moving structure 53. When the moving structure 53 moves, the camera scans along the product 1 and obtains the coplanarity information of the product 1 through the interaction between the laser line and the product 1. The visual inspection system 50 also includes a data processing unit for receiving and processing the data obtained by the 3D line scan camera 51 and outputting the results to a display or control system. The 3D line scan camera 51 can provide high-precision three-dimensional measurement, ensuring accurate detection of the coplanarity of the product 1.
