[0002] Drivers are key components in the electronic component industry, typically consisting of a circuit board, power supply, power converter, and controller. They are used to control the operation of electronic devices by controlling the current, voltage, and drive timing of the driver output. After the driver is manufactured, its function and the appearance of the display need to be inspected. Existing methods often involve manually connecting the driver to the test equipment circuit, controlling the driver's operation according to the test items, and visually judging whether the test results are qualified based on the driver's screen behavior. However, with the increasing number of driver tests, the differences in the test items required for different drivers, and factors such as manual operator fatigue, experience, and differences in visual observation, manual inspections often result in errors and omissions. Furthermore, recording the test results after manual inspection, such as manually writing them down or manually entering the test results into a computer, is cumbersome. Furthermore, it is difficult to quickly determine whether the driver has been inspected during inspection, leading to repeated inspections, which in turn affects inspection efficiency and the management and statistics of all driver inspection results. Therefore, it is necessary to develop an automatic inspection system for drivers to improve this situation. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] In view of the current situation that manual detection of drivers in the existing technology is prone to errors and is time-consuming and labor-intensive, such as Figures 1 to 3 As shown, a preferred embodiment of the automatic driver detection system of the present invention is shown, which includes a machine tool 1, an MES system, an industrial computer 2 electrically connected to the MES system, a code reader 3, a visual detection device 4 and a display unit 5. The machine tool 1 is provided with a driver carrier 6, the industrial computer 2 can be connected to the driver 7, and the code reader 3 and the camera 401 of the visual detection device 4 are set corresponding to the driver carrier 6.

[0030] like Figure 4 and Figure 5As shown, for example, an industrial computer 2 is installed inside the lower part of the machine tool 1. The industrial computer 2, the code reader 3, the visual inspection device 4 and the display unit 5 are connected to the MES system through lines or built-in communication modules to achieve communication or circuit connection. During the production process of the driver 7, the side of the driver 7 is marked with a QR code 703 for identifying the driver 7 model, workpiece number and other information. The MES system stores a driver 7 detection program and a driver 7 detection result database corresponding to the QR code 703. For example, the driver 7 detection program data is set according to the driver 7 model shown in the QR code 703, and the driver 7 detection result data is set according to the unique workpiece number shown in the QR code 703. The working principle of the above-mentioned driver automatic detection system includes:

[0031] Place the driver 7 to be tested on the driver carrier 6 so that the QR code 703 on the driver 7 corresponds to the reading position of the code reader 3. Manually connect the two ends of the power cord to the power supply and the power interface 701 of the driver 7 to power the driver 7. Manually connect the signal line to the communication interface 702 of the driver 7 and the interface of the industrial computer 2 to realize the detection connection between the industrial computer 2 and the driver 7.

[0032] The QR code 703 on the driver 7 is automatically read by the code reader 3 and uploaded to the MES system. The MES system reads the driver 7 detection program in the database according to the obtained QR code 703 and transmits it to the industrial computer 2 and the visual inspection device 4. The industrial computer 2 sends instructions to the driver 7 according to the obtained driver 7 detection program. After receiving the instructions, the driver 7 runs to make different actions on the screen 704 of the driver 7, for example: displaying different numbers. At the same time, the camera 401 of the visual inspection device 4 is aimed at the screen 704 of the driver 7, and the result of the driver 7 detection program is automatically identified and compared to determine whether the detection is qualified as the detection result. The display unit 5 then outputs the display result and uploads the detection result to the MES system. The power cord and signal line on the driver 7 are manually unplugged, and the driver 7 after detection is removed from the carrier, and the next detection can be carried out.

[0033] On the one hand, compared with relying on manual inspection of the driver 7 according to the driver 7 model and visually judging the inspection results, the above-mentioned driver automatic inspection system adopts the code reader 3 to read the QR code 703 of the driver 7 when it is produced, which can quickly obtain the information of the driver 7 in place and send it as a signal to the MES system, and then control the driver 7 to execute the inspection program through the industrial computer 2, and then replace the manual identification and comparison by the visual inspection device 4, which can avoid errors caused by human factors such as manual experience and recognition differences, realize automatic inspection of the driver 7, and improve the accuracy and reliability of the inspection results of the driver 7; on the other hand, compared with manual inspection and then manually entering or recording the inspection results, the above-mentioned driver automatic inspection system can ... After the detection results are obtained, not only can the display unit 5 display the detection results so that the staff can promptly understand the detection results of the detected driver 7, but the visual detection device 4 can also feed back the detection results to the MES system so that the MES system can store the detection results in correspondence with the unique QR code 703 of the detected driver 7, thereby simplifying the statistical recording of the detection results. After the code reader 3 reads the QR code 703 of the driver 7 to be detected, the MES system can also identify whether the detected driver 7 has been inspected based on the stored database, and then the display unit 5 will display and inform the staff, avoiding repeated detection of the driver 7, and further avoiding missed detection and repeated detection, thereby improving the detection efficiency of the driver 7 and reducing the difficulty and labor intensity of manual operation.

[0034] Furthermore, the driver carrier 6 is provided with a plurality of stoppers 8, and an opening 801 is provided between at least two stoppers 8; for example: Figure 3 As shown, a plurality of stoppers 8 above the driver carrier 6 form a U-shaped structure, such as Figure 4 As shown, when the driver 7 to be inspected is placed on the driver carrier 6, it can be pushed in through the U-shaped opening 801 until the driver 7 is limited by the left and right stops 8 and the rear stop 8, so as to realize rapid positioning of the driver 7, so that the code reader 3 can read the QR code 703 and the visual inspection device 4 can identify the screen 704 of the driver 7. A fourth waist-shaped hole 802 can be provided on the stop 8 to adjust the installation position on the driver carrier to adapt to the positioning requirements of different drivers.

[0035] Furthermore, the opening 801 gradually expands outward; for example: Figure 3 As shown, the inner ends of the blocking members 8 on both sides of the driver carrier 6 are provided with chamfers 803 so that the opening 801 gradually expands outward, making it easier to put the driver 7 in and out and reducing the risk of collision.

[0036] Furthermore, the machine tool 1 is provided with a first support frame 9, and the code reader 3 is located on the side of the driver carrier 6. The code reader 3 can adjust the installation height, front and rear position, and left and right position relative to the first support frame 9; for example: Figures 2-4As shown, the code reader 3 is installed on the first support member. The front, back, left, right and height adjustment of the code reader 3 on the first support frame 9 can facilitate the installation and debugging of the code reader 3, so that the code reader 3 is higher than the block 8, and the code reader 3 can scan the QR code 703 on the side of the driver 7.

[0037] Furthermore, the machine tool 1 is provided with a plurality of mounting holes 101, and the first support frame 9 is provided with a first waist-shaped hole 901 and a second waist-shaped hole 902. The first waist-shaped hole 901 is horizontal and can cooperate with the mounting hole 101, and the second waist-shaped hole 902 is vertical and can cooperate with the code reader 3; for example: Figure 3 As shown, the first support frame 9 is an L-shaped structure. The front, rear, left, and right positions of the first support frame 9 on the machine tool 1 can be adjusted by connecting it with the first waist-shaped hole 901 and the mounting hole 101 through bolts and nuts. The installation height of the code reader 3 on the first support frame 9 can be adjusted by connecting it with the code reader 3 on the second waist-shaped hole 902 through bolts and nuts, thereby realizing rapid installation and position debugging of the code reader 3.

[0038] Furthermore, the machine tool 1 is provided with a second support frame 10, and the visual inspection device 4 is located above the driver carrier 6. The visual inspection device 4 can adjust the installation height and left and right position relative to the second support frame 10; for example: Figures 2-4 As shown, the visual detection device 4 is installed on the second support frame 10 and is located above the block 8. By adjusting the installation height and left and right position of the visual detection device 4, the camera 401 of the visual detection device 4 can be located at an appropriate height and corresponding position of the driver 7 screen 704, so as to debug the installation position of the visual detection device 4.

[0039] Furthermore, the visual inspection device 4 is provided with a mounting plate 12, and the mounting plate 12 is provided with a third waist-shaped hole 121 that cooperates with the second support frame 10; for example: Figure 2 As shown, the second support frame 10 adopts a door-shaped structure composed of several frame profiles 11, the third waist-shaped hole 121 is vertically arranged, and the mounting plate 12 of the visual inspection device 4 is bolted through the third waist-shaped hole 121 and the frame profile 11 and then locked with a nut. The installation height and left and right position of the visual inspection device 4 on the second support frame 10 can be adjusted, and the structure is simple and the installation is stable.

[0040] Furthermore, the display element 5 includes a display screen 501 and / or an alarm light 502; for example: the display screen 501 is arranged above the machine tool 1, and can digitally indicate whether the test result is qualified or unqualified, and the alarm light 502 can adopt a three-color alarm light 502, which indicates whether the test result is qualified or unqualified by color. By choosing to use either the display screen 501 or the alarm light 502 or both at the same time, the staff can understand the test results in a timely manner.

[0041] Furthermore, the machine tool 1 is provided with a start button 13 electrically connected to the MES system; for example: when the driver 7 is manually placed on the driver carrier 6 and the driver 7 is connected to the power supply and communication interface 702, the start button 13 can be manually pressed to feedback to the MES system, controlling the code reader 3 to read the QR code 703 on the side of the driver 7, so as to further avoid erroneous results or production safety hazards caused by misoperation.

[0042] Furthermore, it includes an input device 14 electrically connected to the MES system; for example: Figure 1 As shown, the machine tool 1 is provided with a folding stand 102 , and the folding stand 102 is provided with a keyboard 141 and a mouse 142 as input devices 14 for inputting commands or debugging the MES system.
