[0002] With the increasing prevalence of smartphones, tablets, and other electronic devices, the quality of screen cover glass has become a crucial factor in ensuring user experience. The resistivity of the cover glass not only affects display quality but also closely relates to the device's operational performance. Therefore, determining the resistance specifications is paramount to ensuring product quality. Limitations of traditional resistance determination methods:

[0003] Determining the resistance specifications of conventional screen cover glass typically relies on manual measurement using a multimeter and judgment based on accumulated experience. Therefore, this traditional method has the following limitations:

[0004] High labor costs: Manual inspection requires a lot of manpower, is labor-intensive, and is prone to human error.

[0005] Inefficient: Manual testing is slow and cannot meet the needs of large-scale production.

[0006] Insufficient data accuracy: Due to limitations in the professional competence and experience of the testing personnel, the stability and consistency of the test results are difficult to guarantee.

[0007] Data and judgment results are not traceable: Traditional manual testing requires visual readings and immediate determination of product specifications, and data can only be recorded manually. Therefore, data and judgment results are difficult to preserve and trace.

[0008] In conclusion, the display module industry urgently needs more efficient and accurate resistance determination technology to address these challenges. Summary of the Invention

[0009] This invention addresses the problems of existing technologies by providing a CG cover plate resistance measurement device and method, which simplifies the resistance specification determination process to complete the resistance specification determination of the CG cover plate; at the same time, it can transmit resistance data, determination results and corresponding product serial numbers to the MES system in real time, which not only reduces the complexity of equipment use, but also significantly improves work efficiency.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] This invention provides a CG cover plate resistance measuring device, which includes a testing mechanism, a multimeter, and a host computer. The testing mechanism includes a base, a cover plate positioning frame mounted on the base, a stand mounted on the base, a limiting seat located on the front side of the stand, a test pressure rod movably passing through the limiting seat, and a pressure rod driving component for driving the test pressure rod to move up and down. An elastic reset component is sleeved on the outer periphery of the test pressure rod, and the two ends of the elastic reset component are respectively connected to the limiting seat and the stand. A test probe is provided at the lower end of the test pressure rod. The pressure rod driving component is electrically connected to the host computer, the test probe is connected to the multimeter, and the multimeter is signal-connected to the host computer. After the test probe completes the measurement, the host computer sends a command to receive the resistance data returned by the multimeter.

[0012] The base is equipped with two start buttons that are connected to the host computer, and the two start buttons are connected in series.

[0013] The cover plate positioning frame is also provided with multiple vacuum adsorption holes, which are arranged in an array.

[0014] The lower end of the test pressure rod is connected to a horizontal pressure plate, and the test probe is disposed on the lower end face of the horizontal pressure plate.

[0015] The test probe and the multimeter can each be configured in multiple ways.

[0016] The elastic reset element is a spring.

[0017] The present invention also provides a method for measuring the resistance of a CG cover plate, which includes the following steps: Step S10, adjustment of the measuring device: Before measuring the resistance of the product, the position of the test probe is adjusted or the test probe is replaced according to the product size and test point, and the measurement point and measurement time are preset.

[0018] Step S20, Measurement System Initialization: The measurement system initialization process ensures the correct connection and configuration between the measuring device, multimeter, and host computer;

[0019] Step S30: Load the product and scan the QR code to obtain the product's unique identification information;

[0020] Step S40: Start the measuring device and apply appropriate pressure to make the test probe contact the CG cover plate to be tested;

[0021] Step S50: Measure the resistance data and transmit it to the host computer for processing;

[0022] Step S60: Determine the result and output the result to the host computer for classification;

[0023] Step S70: Import the judgment result into the MES system.

[0024] In step S20, during startup, the system attempts to read the configuration file to obtain the relevant test modes, test thresholds, and corresponding multimeter numbers. After the tester enters the workstation number and personnel number, they enter the running mode. On the host computer's software interface, they input the product's SN code or scan the product's QR code. The system sends instructions to the multimeter to test the communication and line connection status. If the host computer receives the data returned by the multimeter, the initialization is successful; otherwise, the initialization fails.

[0025] The measured resistance data is transmitted to the host computer in real time, and the computer automatically determines whether the resistance specifications are qualified based on the preset threshold.

[0026] The beneficial effects of this invention are:

[0027] The embodiments of the present invention have a clever design. Before conducting product resistance measurement, it is necessary to fully consider the differences in product dimensions and test points; this process usually involves replacing or adjusting the test probes and product holders to adapt to CG cover plates of different sizes and types, ensuring that each measurement can be carried out accurately. After completing the adjustment of the measuring device, the entire measurement system needs to be initialized. Before starting the initialization, the measuring device, multimeter and host computer need to be connected by lines, then the database of the multimeter is imported, and then the initialization of the entire system can be started. After completing the adjustment of the measuring device and the initialization of the measurement system, the loading operation can be carried out. Special attention shall be paid during loading to ensure that the product is stably placed in the cover plate positioning frame, so as to ensure that the test probe can accurately reach the designated test point. At the same time, in order to protect the product from damage, the operator shall carefully check the fit between the cover plate positioning frame and the product, and avoid applying excessive pressure to ensure that no physical damage is caused to the product during the test process. After that, the operator needs to use a code scanning gun to scan the two-dimensional code on the product. The two-dimensional code stores important information related to the product, such as product model, batch number and other parameters. This operation not only facilitates subsequent data storage, but also enables effective traceability management, so that each measurement process can be recorded and tracked. Start the measuring device: after completing product loading and two-dimensional code scanning, the operator needs to press two start buttons at the same time to start the test device. Then, the test probe moves towards the preset measurement point to measure the resistance data and transmit it to the host computer. After the test probe reaches the measurement point, the multimeter starts to measure the resistance data of the product. After the measurement is completed, the host computer sends an instruction to receive the resistance data returned by the multimeter. At the same time, the measuring device resets, and then the result is judged. When the resistance data simultaneously meets the set threshold conditions, the product is judged to be qualified; otherwise, the product is judged to be unqualified. Meanwhile, the judgment result is output to the host computer for the convenience of classification by the operator. The embodiments of the present invention aim to simplify the resistance specification judgment process. Any trained operator can easily master it, so as to complete the resistance specification judgment of CG cover plates. At the same time, the system can transmit the resistance data, judgment results and corresponding product serial numbers (SN codes) to the MES system in real time. This design not only reduces the complexity of equipment use, but also significantly improves the work efficiency. In addition, the present invention can be applied to the resistance specification judgment of different models of CG cover plates. Only simple adjustment and initialization operations on the device are required to realize fast and real-time resistance specification judgment of CG cover plates, which not only ensures the judgment accuracy, but also greatly improves the actual production efficiency.

[0034] Example 1

[0035] Embodiment 1 of this application provides a CG cover plate resistance measuring device, such as Figure 1As shown, it includes a testing mechanism, a multimeter 1, and a host computer 2. The testing mechanism includes a base 3, a cover plate positioning frame 4 mounted on the base 3, a stand 5 mounted on the base 3, a limiting seat 6 located on the front side of the stand 5, a test pressure rod 7 movably passing through the limiting seat 6, and a pressure rod driving component for driving the test pressure rod 7 to move up and down. An elastic reset component 8, which is a spring, is sleeved on the outer periphery of the test pressure rod 7. The two ends of the elastic reset component 8 are respectively connected to the limiting seat 6. The base 6 and the stand 5 are provided with a test probe 9 at the lower end of the test pressure rod 7. The pressure rod drive is electrically connected to the host computer 2. The test probe 9 is connected to the multimeter 1. The multimeter 1 is signal connected to the host computer 2. After the test probe 9 completes the measurement, the host computer 2 sends a command to receive the resistance data returned by the multimeter 1. The cover plate positioning frame 4 is also provided with a plurality of vacuum adsorption holes 11, which are arranged in an array. A cover plate positioning groove is formed in the cover plate positioning frame 4. Specifically, in this application, the CG cover plate is positioned within the cover plate positioning frame 4 and adsorbed through multiple vacuum adsorption holes 11 to stably hold the CG cover plate under test, ensuring the stability of the CG cover plate's position during the test and thus improving the reliability of the measurement results. Furthermore, after positioning the CG cover plate, the test probe 9 is controlled by the pressure rod drive to move downwards and contact the CG cover plate to measure the resistance. The elastic reset component 8 ensures that the test pressure rod 7 can automatically return to its initial position after the test is completed. The multimeter 1 is used for the actual resistance measurement, while the host computer 2 is responsible for the control, data reception, and processing of the entire process. After the test probe 9 reaches the measurement point, the multimeter 1 begins to measure the product's resistance data. After the measurement is completed, the host computer 2 sends a command to receive... The device receives the resistance data returned by multimeter 1; simultaneously, the pressure rod drive and test pressure rod 7 are reset. This embodiment of the application realizes automated measurement, improves measurement efficiency and accuracy, and reduces manual intervention, thereby completing the resistance specification determination of the CG cover plate. At the same time, the device can transmit resistance data, determination results, and corresponding product serial number (SN code) to the MES system in real time. This design not only reduces the complexity of equipment use but also significantly improves work efficiency. In addition, this application can be applied to the resistance specification determination of different models of CG cover plates. Only simple adjustments (e.g.) and initialization operations are needed to achieve fast and real-time CG cover plate resistance specification determination, which not only ensures the accuracy of the determination but also greatly improves the efficiency of actual production.

[0036] In this embodiment, the base 3 is provided with two start buttons 10 electrically connected to the host computer 2, and the two start buttons 10 are connected in series. Specifically, the two start buttons 10 are connected in series, so that the operator needs to press both buttons simultaneously to trigger the measurement process; this increases the safety of operation and prevents misoperation.

[0037] In this embodiment, the lower end of the test pressure rod 7 is connected to a horizontal pressure plate 12, and the test probe 9 is disposed on the lower end surface of the horizontal pressure plate 12. Specifically, the lower end of the test pressure rod 7 is connected to the horizontal pressure plate 12, and the test probe 9 is mounted on its lower surface to ensure uniform pressure distribution at all test points; this allows the test probe 9 to simultaneously and uniformly contact multiple test points, improving the efficiency and consistency of measuring multiple points at once.

[0038] In this embodiment, multiple test probes 9 and multiple multimeters 1 can be provided. Specifically, under the above configuration, multiple test probes 9 and multiple multimeters 1 can be configured to simultaneously measure multiple positions or parameters, further improving testing efficiency and making it suitable for more complex testing needs.

[0039] Example 2

[0040] In Embodiment 2 of this application, as Figures 2 to 3 The method for measuring the resistance of a CG cover plate, as shown, includes the following steps:

[0041] Step S10, Measurement device adjustment: Before measuring the product resistance, adjust the position of the test probe 9 or replace the test probe 9 according to the product size and test point location, and preset the measurement point and measurement time.

[0042] Step S20, Measurement System Initialization: The measurement system initialization process ensures the correct connection and configuration between the measuring device, multimeter 1, and host computer 2.

[0043] Step S30: Load the product and scan the QR code to obtain the product's unique identification information;

[0044] Step S40: Start the measuring device and apply appropriate pressure to make the test probe 9 contact the CG cover plate to be tested;

[0045] Step S50: Measure the resistance data and transmit it to the host computer 2 for processing;

[0046] Step S60: Determine the result and output the result to the host computer 2 for classification;

[0047] Step S70: Import the judgment result into the MES system; The product result and its SN code after judgment will be imported into the MES system in real time. Whether the result is qualified, pending inspection, or unqualified, it will be accurately recorded and associated with the corresponding SN code. The SN code of each product is its unique identifier in the production process, which can effectively track its production and testing history.

[0048] Specifically, the embodiments of this application are ingeniously designed. Before measuring the product resistance, the differences in product size and test points need to be fully considered. This process typically involves replacing or adjusting the test probe 9 and the product bracket. It adapts to different sizes and types of CG cover plates to ensure accurate measurements each time. After adjusting the measuring device, the entire measuring system needs to be initialized. Before initialization, the measuring device, multimeter 1, and host computer 2 need to be connected, and then the database of multimeter 1 is imported. Next, the initialization of the entire system can begin. After adjusting the measuring device and initializing the measuring system, the loading operation can be performed. Loading requires... Special care should be taken to ensure the product is securely placed within the cover positioning frame 4 to guarantee that the test probe 9 can accurately reach the designated test point. Simultaneously, to protect the product from damage, the operator should carefully check the fit between the cover positioning frame 4 and the product, avoiding excessive pressure to ensure no physical damage is caused during testing. Next, the operator needs to scan the QR code on the product using a barcode scanner. The QR code stores important information related to the product, such as the product model, batch number, and other parameters. This operation not only facilitates subsequent data storage but also enables effective traceability management, allowing each measurement process to be recorded and tracked. Finally, the measuring device should be started.

[0049] After the product loading and QR code scanning are completed, the operator needs to press both start buttons 10 simultaneously to start the testing device. Then, the test probe 9 will move towards the preset measurement point, measure the resistance data and transmit it to the host computer 2. After the test probe 9 reaches the measurement point, the multimeter 1 starts measuring the product's resistance data. After the measurement is completed, the host computer 2 sends a command to receive the resistance data returned by the multimeter 1. At the same time, the measuring device is reset. The result is then judged. When the resistance data meets the set threshold conditions, the product is judged to be qualified; otherwise, the product is judged to be unqualified. Simultaneously, the judgment result is output to the host computer 2 for easy classification by operators. This embodiment aims to simplify the resistance specification judgment process; any trained operator can easily master it to complete the resistance specification judgment of the CG cover plate. Furthermore, the system can transmit resistance data, judgment results, and the corresponding product serial number (SN code) to the MES system in real time. This design not only reduces the complexity of equipment use but also significantly improves work efficiency. In addition, this application can be applied to the resistance specification judgment of different models of CG cover plates. Only simple adjustments and initialization operations are needed to achieve fast and real-time CG cover plate resistance specification judgment. This ensures the accuracy of the judgment and greatly improves the efficiency of actual production.

[0050] In this embodiment of the application, the adjustment of the measuring device in step S10 includes:

[0051] Step S11: Adjustment of test probe 9. First, for products of different sizes, to ensure that the test probe 9 can accurately contact the area to be tested, it may be necessary to select a suitable probe type and length. At the same time, the shape and material of the test probe 9 may also vary depending on the properties of the object being measured, to ensure good conductivity and reliable measurement results.

[0052] Step S12: Adjustment of cover plate positioning frame 4. The adjustment of cover plate positioning frame 4 is equally important. It is not only responsible for stabilizing the product under test, but also for ensuring its correct alignment with the test probe 9. Cover plate positioning frames 4 of different heights and shapes can help locate the best measurement point of the product and avoid errors caused by improper positioning.

[0053] Step S13: Set measurement points and measurement time. Based on the differences in test points for different products, set the measurement points and measurement time to ensure that the probe can stably obtain effective readings and improve overall testing efficiency.

[0054] In this embodiment, in step S20, the system attempts to read the configuration file upon startup to obtain the relevant test modes, test thresholds, and the corresponding multimeter 1 number. The tester enters the operating mode after inputting their workstation number and personnel number. On the software interface of the host computer 2, the system inputs the product's SN code or scans the product's QR code. The system sends instructions to the multimeter 1 to test communication and line connection. If the host computer 2 receives the data returned by the multimeter 1, initialization is successful; otherwise, initialization fails. Specifically, after adjusting the measuring device, the entire measuring system needs to be initialized. Before initialization, the measuring device, multimeter 1, and host computer 2 need to be connected, and then the database of multimeter 1 needs to be imported. Next, the initialization of the entire system can begin, with the following steps: First, the system attempts to read the configuration file upon startup to obtain the relevant test modes, test thresholds, and the corresponding multimeter 1 number. If reading fails, the test mode, test threshold, and corresponding multimeter 1 number need to be manually input or selected. Second, the tester needs to enter their workstation number and personnel number to enter the operating mode. Next, you can enter the product's serial number (SN) or scan the product's QR code in the software interface of host computer 2. The system will then send a command to multimeter 1 to test the communication and line connection. Thirdly, if host computer 2 receives data returned by multimeter 1, the initialization is successful. Otherwise, the initialization has failed. If initialization fails, you can check the connection lines and repeat the above steps to perform initialization.

[0055] In the embodiment of the present application, the product is loaded and the two-dimensional code is scanned: after the adjustment of the measuring device and the initialization of the measuring system are completed, the loading operation can be carried out; during loading, special attention shall be paid to ensuring that the product is stably placed in the product holder, so as to ensure that the test probe 9 can accurately reach the designated test point; at the same time, in order to protect the product from damage, the operator shall carefully check the fit between the holder and the product, avoid applying excessive pressure, and ensure that no physical damage is caused to the product during the test. After that, the operator needs to use a code scanner to scan the two-dimensional code on the product. The two-dimensional code stores important information related to the product, such as product model, batch number and other parameters. This operation not only facilitates subsequent data storage, but also enables effective traceability management, so that each measurement process can be recorded and tracked.

[0056] In the embodiment of the present application, step S40: start the measuring device. After completing the product loading and two-dimensional code scanning, the operator needs to press two start buttons 10 at the same time to start the test device. After that, the test probe 9 moves towards the preset measuring point; S50: measure the resistance data and transmit it to the upper computer 2. After the test probe 9 reaches the measuring point, the multimeter 1 starts to measure the resistance data of the product. After the measurement is completed, the upper computer 2 sends an instruction to receive the resistance data returned by the multimeter 1; at the same time, the measuring device resets.

[0057] In the embodiment of the present application, the measured resistance data is transmitted to the upper computer 2 in real time, and it is automatically determined whether the resistance specification is qualified according to the preset threshold. If the resistance data simultaneously meets the set threshold conditions, the product is determined to be qualified. Otherwise, the product is determined to be unqualified. Meanwhile, the determination result is output to the upper computer 2 to facilitate the classification by the operator.

[0058] Preferably, three test probes 9 are provided, which are used to test three points on the same CG cover plate. Through the combination of two sets of detection points, the resistance R1 and resistance R2 of the two sets of detection points on the CG cover plate are tested by two resistance multimeters 1 to obtain the resistance data R1 and R2. When the resistance R1 and the resistance R2 simultaneously meet the set threshold conditions, the product is determined to be qualified; otherwise, the product is determined to be unqualified. Meanwhile, the determination result is output to the upper computer 2 to facilitate the classification by the operator.
