Whether they are qualified, pending inspection or unqualified, they will be accurately recorded and associated with the corresponding SN codes. The SN code of each product is its unique identity in the production process, which can effectively track its production and testing history.

[0048] Specifically, the embodiment of the present application is cleverly designed. Before measuring the resistance of a product, it is necessary to fully consider the differences in product size and test points. This process usually involves replacing or adjusting the test probe 9 and the product bracket. Adapting to CG covers of different sizes and types ensures that each measurement can be performed accurately. After the adjustment of the measuring device is completed, the entire measuring system needs to be initialized. Before starting the initialization, it is necessary to connect the measuring device, the multimeter 1, and the host computer 2, and then import the database of the multimeter 1, and then the initialization of the entire system can be started. After completing the adjustment of the measuring device and the initialization of the measuring system, the loading operation can be performed. Pay special attention to ensure that the product is securely placed in the cover positioning frame 4 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 should carefully check the fit between the cover positioning frame 4 and the product, and avoid excessive pressure to ensure that no physical damage is caused to the product during the test; after that, the operator needs to use a barcode scanner to scan the QR code on the product; the QR 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 realizes effective traceability management, so that each measurement process can be recorded and tracked; start the measuring device.

[0049] After completing product loading and QR code scanning, the operator needs to press two start buttons 10 at the same time to start the test 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 to measure the resistance data of the product. 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; and then the result is determined. When the resistance data meets the set threshold conditions at the same time, the product is determined to be qualified; otherwise, the product is determined to be unqualified. At the same time, the determination result is output to the host computer 2, which is convenient for the operator to classify; the embodiment of the present application is intended to simplify the resistance specification determination process; any trained operator can easily master it, thereby completing the resistance specification determination of the CG cover plate; at the same time, the system can transmit the resistance data, determination result 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, the present application can be applied to the resistance specification determination of CG cover plates of different models, and only simple adjustment and initialization operations are required to the device to achieve fast and real-time CG cover plate resistance specification determination. That is, the accuracy of the determination is guaranteed, and the efficiency of actual production can be greatly improved.

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

[0051] Step S11: Adjustment of the test probe 9. First, for products of different sizes, in order 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 to be tested, in order to ensure good conductivity and reliable measurement results.

[0052] Step S12: Adjust the cover positioning frame 4. The adjustment of the cover positioning frame 4 is equally important. It is not only responsible for stabilizing the product to be tested, but also needs to ensure the correct alignment between it and the test probe 9. Cover positioning frames 4 of different heights and shapes can help locate the best measuring point of the product and avoid errors caused by improper positioning.

[0053] Step S13: Setting the measurement point and measurement time. According to the differences in test points of different products, the measurement point and measurement time are set to ensure that the probe can stably obtain effective readings and improve the overall test efficiency.

[0054] In the embodiment of the present application, in the step S20, the configuration file will be tried to be read at startup to obtain the relevant test mode, test threshold and the corresponding multimeter 1 number; the tester enters the station number and the personnel number and enters the operation mode, enters the SN code of the product or scans the QR code of the product in the software interface of the host computer 2, and the system sends instructions to the multimeter 1 to test the communication and line connection; if the host computer 2 receives the data returned by the multimeter 1, the initialization is successful; otherwise, the initialization fails. Specifically, after the adjustment of the measuring device is completed, the entire measurement system needs to be initialized, and the measuring device, the multimeter 1 and the host computer 2 need to be connected by line before the initialization begins, and then the database of the multimeter 1 is imported. Next, the initialization of the entire system can be started, and the steps are as follows: the first step, the system will try to read the configuration file at startup to obtain the relevant test mode, test threshold and the corresponding multimeter 1 number. If the reading fails, it is necessary to manually enter or select the test mode, test threshold and select the corresponding multimeter 1 number. The second step is to enter the operation mode after the tester enters the station number and the personnel number. After that, you can enter the product's SN code or scan the product's QR code in the software interface of the host computer 2, and the system will send instructions to the multimeter 1 to test the communication and line connection. Step 3: If the host computer 2 receives the data returned by the multimeter 1, the initialization is successful. Otherwise, the initialization fails. If the initialization fails, you can check the connection line and repeat the above steps to initialize.

[0055] In the embodiment of the present application, the product is loaded and the QR 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; when loading, special attention should be paid to ensure that the product is securely placed in the product holder 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 should carefully check the fit between the holder and the product, and avoid excessive pressure to ensure that no physical damage is caused to the product during the test. After that, the operator needs to use a barcode scanner to scan the QR code on the product. The QR code stores important information related to the product, such as product model, batch number and other parameters. This operation not only facilitates subsequent data preservation, 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 product loading and QR 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 will move towards the preset measurement point; S50: 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 to measure the resistance data of the product. 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.

[0057] In the embodiment of the present application, the measured resistance data is transmitted to the host computer 2 in real time, and the resistance specification is automatically determined to be qualified according to the preset threshold. If the resistance data meets the set threshold conditions at the same time, the product is determined to be qualified. Otherwise, the product is determined to be unqualified. At the same time, the determination result is output to the host computer 2 for easy classification by the operator.

[0058] Preferably, three test probes 9 are provided, and three points on the same CG cover are tested by the three test probes 9. Through the combination of two groups of detection points, the resistance data R1 and R2 of the two groups of detection points of the CG cover are tested by two resistance multimeters 1. When the resistance R1 and the resistance R2 simultaneously meet the set threshold conditions, the product is judged as qualified; otherwise, the product is judged as unqualified. At the same time, the judgment result is output to the host computer 2 for easy classification by the operator.

[0059] The key points of the embodiments of this application are:

[0060] Key point 1: In view of the problems of low efficiency and inaccurate data in the traditional manual CG cover resistance measurement, the present invention has developed a CG cover resistance measurement device. The device can flexibly replace any resistance measuring instrument, test probe, product bracket and other components according to measurement requirements and product differences, thereby improving measurement efficiency and accuracy.

[0061] Key point 2: In order to solve the problems of low efficiency and inconsistent judgment standards in the traditional resistance specification determination method, which requires manual data recording, the present invention develops a corresponding host computer 2 algorithm. By simply transmitting the resistance data collected by the CG cover resistance measurement device to the host computer 2, real-time and accurate cover resistance determination can be achieved.
