[0013] The present application provides a co-line test control method and system for a two-station polarity tester, which is used to solve the technical problems of low test efficiency, large manual error, and insufficient automation in existing battery module polarity detection equipment in the prior art.

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0015] It should be noted that the terms "first", "second", etc. in the specification of the present application and the above accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or server including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or modules that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0016] Embodiment 1, as Figure 1 shown, the present application provides a co-line test control method for a two-station polarity tester. The method is applied to a two-station polarity tester, and the two-station polarity tester includes two test stations. Each test station is provided with a micro switch, a test device, and a cylinder mechanism. The method includes:

[0017] P10: Place the battery module in the first test station of the two test stations, and use the micro switch to confirm the positioning of the battery module, and send a positioning completion signal.

[0018] Optionally, the operator accurately places the battery module to be tested on the first test station of the double-station polarity tester. The double-station polarity tester includes a first test station and a second test station. The first test station is one of the independent working units in the double-station polarity tester and is used for the preliminary positioning and polarity testing of the battery module. To ensure the accurate position of the battery module during the test, the tester is equipped with a microswitch, which plays a role in position confirmation when the battery module reaches a specific position.

[0019] The microswitch is a highly sensitive switch device, usually used to sense the contact or position change of an object. In this application, the role of the microswitch is to confirm that the battery module has been correctly positioned when it is placed in the first test station. Specifically, when the battery module reaches the predetermined position, the microswitch will be triggered, generating an electrical signal indicating that the module is in the appropriate test position. The sensitivity of the microswitch ensures the high precision of this positioning process and avoids test errors caused by inaccurate positioning.

[0020] Once the microswitch is triggered, the tester will immediately send a positioning completion signal to notify the control system that the battery module has successfully reached the test position and is ready for the next step of polarity testing. This signal not only marks the end of the positioning process but also effectively prevents incorrect testing due to incomplete positioning during the test. Through this precise positioning confirmation mechanism, the entire test process can be smoothly started and also provides a basis for subsequent steps to ensure test accuracy and system reliability.

[0021] P20: According to the positioning completion signal, start the test device of the first test station to perform the cell polarity test and generate the cell polarity test result.

[0022] Among them, the test device includes a test probe board and a probe mechanism. The test probe board is replaceably set according to the cell specifications, and the probe mechanism is automatically moved up and down through test software control.

[0023] Furthermore, step P20 of the embodiment of this application further includes:

[0024] P21: After pressing the test start button of the test station, the control system drives the probe mechanism to descend so that the probe contacts the test points of the battery module; P22: Activate the test software and sequentially scan and test the cell polarities of the battery module according to the preset channels, record the voltage and current directions of each channel, and generate the cell polarity test result.

[0025] It should be understood that when the battery module completes positioning at the first test station and is confirmed by the microswitch, the control system receives the positioning completion signal and then activates the test device at the first test station to perform the cell polarity test.

[0026] The test device consists of a test probe board and a probe mechanism. The design of these components improves the automation and accuracy of the cell polarity test. First, the test probe board can be replaceably set according to the cell specifications of the battery module during design, which can ensure good contact between the test probes and the cells of different types of battery modules, thereby improving the reliability and compatibility of the test. This design meets the requirements of different specifications of battery modules and avoids the problem of poor versatility caused by a fixed probe board.

[0027] The probe mechanism is a very critical component during the test process and is responsible for accurately inserting the test probes into the test points of the battery module to detect the cell polarity. The movement of the probe mechanism is driven by the test software through the control system, usually through an electric actuator to achieve automatic up and down movement, ensuring that the probes can accurately contact the test points according to the predetermined path.

[0028] Specifically, before the test is started, the operator presses the test start button to trigger the control system start command, driving the probe mechanism to move downward so that the test probes make physical contact with the test points of the battery module. During this process, the contact pressure and position between the probes and the cells are crucial. Therefore, the precise control of the probe mechanism can ensure the test accuracy.

[0029] Once the probes make contact with the test points of the battery module, the test software is activated and enters the test mode. The test software automatically performs the cell polarity test according to the preset test channels and test logic. This process includes analyzing the current or voltage of the positive and negative poles of the cells and comparing them with the set test criteria to determine whether the cell polarity is correct. The test software will generate detailed cell polarity test results based on these data and automatically record and save them.

[0030] Through this automated and precisely controlled test method, the efficiency and accuracy of the cell polarity test of the battery module can be greatly improved, avoiding the errors of manual detection and being able to flexibly meet the test requirements of different specifications of batteries.

[0031] Furthermore, step P20 of the embodiment of the present application further includes:

[0032] The test software can automatically identify the specification model of the battery module and automatically configure the number and sequence of test channels according to the set test requirements, supporting the test of 1 to 15 cells.

[0033] In a possible embodiment of the present application, in this embodiment, the test software is not only responsible for controlling the probe mechanism and other hardware components during the test process, but also has an intelligent automatic recognition function. Specifically, after the battery module is placed and its position is confirmed, the test software can automatically recognize the specification model of the battery module, such as parameters like the size of the battery cells, the contact point positions, and the number of battery cells. Through this function, the test system can automatically adjust its test configuration according to different models and specifications of battery modules to ensure test accuracy and efficiency.

[0034] Once the test software recognizes the model of the battery module, the automatic configuration of the number and sequence of test channels follows. The specifications of each battery module may involve different numbers of battery cells (for example, a single-cell battery module may have 1 to 15 battery cells). Therefore, the software will automatically calculate and configure the number of test channels to be used and the corresponding test sequence. For example, if the battery module contains 15 battery cells, the system will automatically configure 15 test channels for one-by-one detection. If the number of battery cells in the module is less, the corresponding number of channels will also decrease.

[0035] The test channel refers to the test point of each battery cell. The software precisely inserts the probe into the contact point of the battery cell through the probe mechanism in the test device for testing. The test sequence refers to the order in which the test software arranges the probe operations according to the layout and priority of the battery cells, ensuring that each battery cell can complete the polarity detection in sequence. Through such intelligent configuration, the test software not only improves the operation efficiency but also reduces test delays and inaccuracies caused by manual configuration or errors.

[0036] This function of automatically adapting based on the specifications of the battery module makes the test device more flexible and efficient, while also improving the automation level and intelligent level of the production line. The entire process requires no manual intervention, thus greatly reducing the risk of human errors and also speeding up the detection process, enabling the satisfaction of the test requirements for large quantities and high-precision battery modules in the production environment.

[0037] Furthermore, step P20 of the embodiment of the present application further includes:

[0038] The test probe board has a replaceable design and supports quickly replacing different models of probe boards according to different specifications of the battery module.

[0039] Optionally, in this embodiment, the test probe board adopts a replaceable design, which significantly improves the adaptability and flexibility of the device. Different types of battery modules have different battery cell specifications and test requirements, including the size of the battery cells, the contact point positions, the pin pitch, etc. To ensure accurate testing, the test device is equipped with multiple models of probe boards, and the contact point positions and arrangement methods of each probe board are specifically designed according to the specifications of the battery module.

[0040] When the specification model of the battery module is detected, the system will select the probe board model that matches it through the automatic recognition function. The operator only needs to install the probe board of the correct model into the testing machine according to the system prompt. This quick replacement design enables the testing device to quickly respond to the needs of different battery modules, avoiding problems such as inaccurate testing or cumbersome operations caused by inconsistent battery module specifications.

[0041] The replaceable probe board usually adopts a modular structure, so that the replacement process can be completed through simple disassembly and installation steps. The design of the probe board takes into account the convenience of operation and the speed of replacement. For example, the probe board may adopt a snap-on structure, enabling the probe board to be quickly locked into the specified position without complex tools or excessive steps. In this way, when the testing equipment faces battery modules of different specifications, it can not only ensure high-precision testing, but also reduce the downtime caused by replacing the probe board, thereby improving production efficiency.

[0042] In addition, the connection between the probe board and the probe mechanism is also precisely designed to ensure that during the replacement process of the probe board, the new probe board can be accurately docked with the existing probe mechanism, avoiding mechanical looseness or poor contact. This technology supports the stability of the equipment in a high-frequency production environment and the reliability of long-term operation.

[0043] In summary, the design of the replaceable probe board enables the testing machine to flexibly handle battery modules of different specifications, ensures the accuracy and efficiency of the cell polarity test, and to a certain extent reduces the operation complexity and downtime caused by specification differences.

[0044] Furthermore, step P20 of the embodiment of the present application further includes:

[0045] The testing device automatically adjusts the parameter settings of the testing station by linking with the testing software to meet the testing requirements of different battery modules.

[0046] Specifically, in this embodiment, the testing device and the testing software cooperate through a close linkage relationship to ensure a high degree of automation and accuracy in the testing process. The testing software can automatically adjust multiple parameter settings related to the testing station according to the model and specifications of the battery module to adapt to the testing requirements of different battery modules. These parameters include but are not limited to probe pressure, test voltage, test time, etc., which are all key factors affecting the cell polarity test results.

[0047] Specifically, when the battery module is accurately placed and positioned, the test software will obtain the cell specifications of the battery module through data recognition, and then automatically configure the test station according to this information. For example, if the battery module uses large batteries or has a multi-layer structure design, the test software will automatically adjust the pressure and contact depth of the probes to ensure that the probes can accurately touch the test points of each cell without damaging the battery. In addition, the test software can also automatically select the appropriate test channels and their sequences according to the specific test requirements of the battery module, maximizing the test efficiency and accuracy.

[0048] Through close cooperation with the hardware, the automatic adjustment function of the test device ensures that during the testing process of battery modules with different specifications, accurate polarity testing can be carried out without manual intervention, thus greatly improving the efficiency of the automated production line and reducing the possibility of human errors.

[0049] P30: According to the cell polarity test results, determine the cell polarity, and according to the determination results, classify and unload the battery module, and generate a signal indicating that the test at the first station is completed.

[0050] It should be understood that the test device first accurately determines the cell polarity of the battery module according to the cell polarity test results. The test software will automatically analyze the test results to identify whether the cells meet the predetermined polarity standards. The polarity detection of cells is a key link to ensure the safety and normal function of the battery module. Especially during the battery assembly process, incorrect polarity may lead to serious performance problems or even safety hazards.

[0051] The cell polarity determination is to identify the positive and negative polarities of the cells through the feedback of current and voltage signals after the test probes are in contact with the cells of the battery module. The software judges whether each cell meets the specified polarity requirements according to the preset determination algorithm. For example, if the positive and negative poles of the cell are reversed, the system will automatically mark it as unqualified and classify the battery module as a defective product.

[0052] According to the polarity determination results, the battery modules will be classified and unloaded. That is, the qualified battery modules will continue to enter the subsequent production process, while the unqualified modules will be automatically separated and excluded from the production line. The classification and unloading are usually achieved through pneumatic devices or automated sorting mechanisms to ensure that the qualified and unqualified modules can be separated in time, preventing incorrect battery modules from entering the next process.

[0053] Finally, based on the completion of the tests, a signal indicating the completion of the tests at the first station is generated to notify the operator or the control system that this testing phase has been successfully completed. This signal is also used to trigger subsequent production steps or the operation of equipment, ensuring the efficient and continuous production process. For example, the test completion signal may trigger the test preparation at the second station or mark the equipment as ready to enter the next batch of tests. Through the above-mentioned automated determination and blanking operations, not only is the test efficiency improved, but also manual intervention and human errors are effectively reduced, ensuring the consistency and reliability of product quality.

[0054] P40: Automatically switch to the second test station according to the signal indicating the completion of the tests at the first station and the signal for loading materials at the second station, and so on, alternatingly.

[0055] Among them, the dual-station polarity testing machine adopts a dual-station alternating testing method. During testing, one station conducts tests while the other station performs manual loading or unloading, alternatingly, including:

[0056] When conducting battery module tests at the first test station, the blanking operation and the loading operation are completed at the second test station. The blanking operation is automatically completed by a cylinder mechanism, which pushes the tested battery module to the blanking area. The loading operation uses a cylinder mechanism to send the battery module to be tested into the second test station for positioning.

[0057] Optionally, the dual-station polarity testing machine realizes an efficient production process through the dual-station alternating testing method. In this method, when the first test station completes the polarity test of the battery module and generates a signal indicating the completion of the tests at the first station, the system will automatically switch to the second test station to conduct tests on the next battery module. At the same time, the battery module at the first test station has completed the test and can be processed for blanking. The second test station starts the test, while the first station prepares to receive a new battery module and conduct loading.

[0058] Specifically, while the battery module is being tested at the first test station, the second test station is responsible for the blanking operation and the loading operation. These two operations are automatically completed by a cylinder mechanism, ensuring seamless connection and rapid switching between stations. When the first station completes the cell polarity test, the test results are determined and a test completion signal is generated. At this time, the cylinder mechanism starts and automatically pushes the tested battery module to the blanking area for subsequent processing (such as sorting, storage, etc.). The cylinder ensures the smooth and stable removal of the battery module from the test area through precisely controlled up and down movements and a pushing device. At the second test station, the cylinder mechanism will automatically send the battery module to be tested into the second station for testing while the first station is completing the blanking. The movement of the cylinder is precisely scheduled by the control system to ensure that the battery module to be tested can accurately and stably enter the test station, avoiding affecting the test results due to inaccurate positioning.

[0059] In this alternating manner, the dual-station system can maximize the test efficiency without wasting time. When one station is conducting tests, the other station is responsible for loading or unloading materials, ensuring that the work of each station is fully utilized, thus shortening the overall test cycle and improving the efficiency of the production line.

[0060] In addition, the design of dual-station alternating testing not only increases the test speed of the equipment but also greatly reduces the labor intensity of the operator because most of the loading, unloading, and testing processes can be completed through automated control. This automated and intelligent station switching method is an important manifestation of an efficient production line in modern manufacturing.

[0061] P50: Scan to obtain the order number information of the battery module, and upload the cell polarity test result and the order number information to the MES database for storage.

[0062] In a possible embodiment of the present application, to ensure that the test data of each battery module can be effectively traced and associated with the production order, the order number information of each battery module is automatically obtained through a scanning device. The order number is a unique identifier for identifying key information such as production batches, models, and specifications. After the battery module passes through the test station and completes the polarity test, the cell polarity test result of the module and its corresponding order number information are uploaded to the database of the Manufacturing Execution System (MES) for storage.

[0063] The MES database is a system for managing and storing various data in the production process, providing functions such as production status monitoring, data traceability, and quality control. By associating and storing the order number with the test result, an enterprise can achieve data traceability in the production process and ensure that the quality status of each battery module can be queried and tracked in real time. At the same time, the information uploaded to the MES database can also provide data support for subsequent production scheduling, quality analysis, and product compliance.

[0064] In addition, the automatic upload function can ensure the accuracy and efficiency of the data storage process, avoiding errors or omissions that may be caused by manual recording. This function is particularly important for intelligent factories, supporting enterprises to achieve precise management and rapid response to each battery module in the face of large-scale production.

[0065] In summary, the embodiments of the present application have at least the following technical effects:

[0066] In this application, the battery module is placed in the first test station, and the positioning is confirmed through a microswitch to send a positioning completion signal. Then, the test device at the first station is started to perform the cell polarity test, and the cell polarity is determined according to the test result. The battery modules are classified and discharged, and at the same time, a test completion signal for the first station is generated. According to the test completion signal and the feeding signal at the second station, it is automatically switched to the second test station for testing, and the loading and unloading and testing operations are alternately performed.

[0067] It achieves the technical effect of improving the efficiency, accuracy, and automation level of the cell polarity test through dual-station alternating testing.
