Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a battery docking test device. Background Art

[0002] In the field of battery manufacturing technology, the docking test between the battery and the battery discharge pins and rails is an important task, which directly affects the function and service life of the battery. In the field of mechanical testing technology, how to accurately simulate the stress and wear of the battery during use is an important research topic. In addition, in the field of simulation technology, how to simulate the real environment through computers to improve the accuracy and efficiency of the test is also an important research direction.

[0003] Existing technical solutions: Existing solutions mainly rely on manual testing to connect and separate the battery with the battery discharge pin and rail, and then evaluate the battery's function and service life through observation and measurement. However, this method often cannot accurately simulate the stress and wear of the battery during use throughout its life cycle, so the accuracy of the test results is limited.

[0004] Problems with existing technologies: The problems with existing technologies in this field are mainly as follows: First, the existing test methods cannot achieve a fixed frequency. Second, the existing test methods cannot accurately control the number of times the battery contacts the discharge pins and rails, which may affect the efficiency and accuracy of the test. Finally, the existing test methods cannot accurately control the contact strength between the battery and the discharge pins and rails, which may lead to greater randomness in the test results and the inability to achieve consistency in the test conditions. Summary of the invention

[0005] In order to overcome the above disadvantages, the object of the present invention is to provide a battery docking test device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is a battery docking test device, comprising: The two ends of the battery along the first direction are a handle end and a socket end respectively.

[0007] The base has a docking mechanism and a driving mechanism spaced apart on the top along the first direction, the docking mechanism includes a control box, the control box includes a battery discharge pin, and the battery discharge pin is arranged on a side of the control box facing the docking mechanism.

[0008] The driving mechanism includes a driving cylinder and a connecting plate group, wherein one end of the connecting plate group along the first direction is connected to the driving end of the driving cylinder, and the other end is connected to the handle end of the battery, and is used to drive the connecting plate group through the driving cylinder to drive the battery to move relative to the control box along the first direction so that the socket end of the battery can be connected or separated from the battery discharge pin.

[0009] The battery docking test device provided by the present invention generally requires manual operation to connect and disconnect the battery with the test equipment, which is inefficient and prone to errors. The present invention realizes automatic connection and disconnection of the battery by driving the cylinder and the connecting plate group, reduces manual intervention, improves the convenience of operation and test efficiency, and ensures accurate docking between the battery socket and the discharge pin through precise control of the driving cylinder and stable connection of the connecting plate group.

[0010] In some embodiments, the driving mechanism further comprises a linear guide and a mounting guide plate, wherein the linear guide extends along the first direction and has a slider on the top. The linear guide is disposed on a side of the driving cylinder facing the control box along the first direction. One end of the mounting guide plate along the first direction is connected to the driving end of the driving cylinder, and the bottom is connected to the slider.

[0011] With the above counting scheme, the linear guide adopts rolling friction, which has a low friction coefficient and a small difference between dynamic friction and static friction, and can achieve high-precision positioning to ensure accurate docking between the battery socket and the discharge pin.

[0012] In some embodiments, the connecting plate group includes a first connecting plate, a second connecting plate and a third connecting plate, the first connecting plate extends along the third direction and is connected to the other end of the mounting guide plate along the first direction. The second connecting plate and the third connecting plate are arranged parallel to the upper and lower ends of the first connecting plate along the first direction.

[0013] With the above counting scheme, the connecting plate group is connected to the mounting guide plate through the first connecting plate, and the second connecting plate and the third connecting plate are respectively arranged at the upper and lower ends to form a stable structural frame. This design can effectively disperse the force of the battery during movement and avoid structural deformation or damage caused by excessive local force.

[0014] In some embodiments, a clamping protrusion is provided on the top of the third connecting plate on the side away from the linear guide along the first direction, and the clamping protrusion is configured to match the size of the handle end, and is used to fix the battery through the clamping protrusion and the handle end. A limiting baffle is provided on the bottom of the second connecting plate on the side away from the linear guide along the first direction, and is used to abut against the battery for limiting position.

[0015] With the above counting scheme, the clamping protrusion on the top of the third connecting plate matches the size of the battery handle end, and the battery is fixed by clamping. This design can effectively prevent the battery from loosening or shifting during the test, ensuring the stability of the test. The limit baffle at the bottom of the second connecting plate is used to abut against the battery to limit the movement of the battery and enhance the fixing effect.

[0016] In some embodiments, the docking mechanism further includes a bottom plate, which is disposed on a side of the control box facing the third connecting plate along the first direction and is spaced apart from the third connecting plate. The control box further includes a guide rail, which is disposed on the same side as the battery discharge pin and is disposed below the battery discharge pin. The guide rail extends along the first direction and is supported by the bottom plate. Both ends of the guide rail along the second direction are provided with a bending portion, which is adapted to the bottom size of the battery and is used to abut against the battery for limiting position.

[0017] With the above counting scheme, the bottom plate is arranged on one side of the control box and is spaced apart from the third connecting plate. This structural design provides a stable support platform for the entire docking mechanism, ensuring the stability of the control box and the guide rail during the battery insertion and separation process. The bent parts at both ends of the guide rail are adapted to the bottom of the battery, which can limit the position deviation of the battery during the docking process and further improve the test accuracy.

[0018] In some embodiments, the driving mechanism further includes a limit assembly, and the limit assembly includes a first stop block group and a second stop block group. The first stop block is disposed between the third connecting plate and the bottom plate and is spaced along the second direction, and is used to abut against the third connecting plate to limit position when the socket end of the battery is plugged into the battery discharge pin. The second stop block group is disposed between the third connecting plate and the linear guide rail, and is used to abut against the third connecting plate to limit position when the socket end of the battery is separated from the battery discharge pin.

[0019] By adopting the above counting scheme, through the dual limiting functions of the first stop block group and the second stop block group, the device can provide stable support at the two key stages of battery insertion and separation, reducing errors caused by mechanical vibration or human operation. The first stop block group is arranged between the third connecting plate and the bottom plate to ensure that the battery remains accurately positioned during the insertion process, avoiding insertion failure or poor contact due to position deviation.

[0020] In some embodiments, the control box further includes a counting sensor for detecting and counting the number of times the socket end of the battery is plugged into the battery discharge pin.

[0021] By adopting the above counting scheme, the counting sensor can accurately record the number of times the battery socket end is plugged into the discharge pin. This function enables the test device to monitor the frequency of equipment use in real time, providing data support for equipment maintenance and life evaluation.

[0022] In some embodiments, the battery docking test device further includes a host computer, which is disposed on a side of the driving cylinder away from the control box along the first direction and is signal-connected to the control box and the driving cylinder, respectively.

[0023] By adopting the above counting scheme, the automatic control of the battery insertion and separation process is realized through the signal connection between the host computer and the driving cylinder. The host computer can automatically control the action of the driving cylinder according to the preset program or real-time monitoring data, without manual operation, which significantly improves the test efficiency. The host computer can receive signals from the driving cylinder and other sensors in real time to monitor the status of the battery during docking.

[0044] Exemplarily, the bottom plate 32 is disposed on one side of the control box 30 and is spaced apart from the third connecting plate 45. This structural design provides a stable support platform for the entire docking mechanism, ensuring the stability of the control box 30 and the guide rail 33 during the insertion and separation of the battery 6. The bent portions at both ends of the guide rail 33 are adapted to the bottom of the battery 6, which can limit the positional deviation of the battery 6 during the docking process, further improving the test accuracy.

[0046] For example, through the dual limiting functions of the first stop block group 48 and the second stop block group 49, the device can provide stable support at the two key stages of plugging and detaching the battery 6, reducing errors caused by mechanical vibration or human operation. The first stop block group 48 is arranged between the third connecting plate 45 and the bottom plate 32 to ensure that the battery 6 is accurately positioned during the plugging process, avoiding plugging failure or poor contact due to position deviation.

[0050] For example, the host computer 5 is connected to the driving cylinder 40 by signals, so as to realize the automatic control of the connection and separation process of the battery 6. The host computer 5 can automatically control the action of the driving cylinder 40 according to the preset program or real-time monitoring data, without manual operation, which significantly improves the test efficiency.

At the same time, the host computer 5 can record the test data and generate a detailed test report for subsequent analysis and tracing.

[0051] The specific implementation steps of the battery docking test device provided by this application are as follows: Step 1: Select a suitable dual-axis cylinder as the power source. The working pressure of the cylinder is 0.6-0.8MPa, the maximum stroke is 300mm, and the maximum speed is 500mm / s. By adjusting the pressure and cylinder diameter of the cylinder, different driving forces and speeds can be achieved to meet the needs of simulating different forces and frequencies of force on the battery, battery discharge pins, and guide rails.

[0052] Step 2: A pulling mechanism is set below the dual-axis cylinder. The left end of the pulling mechanism is fixed to the battery handle end. Driven by the cylinder, the mechanism can separate and dock the battery and the battery discharge component along the guide rail, thereby simulating the wear of the battery and the discharge pin during use, including the wear of the sliding guide rail.

[0053] Step 3: Set a positioning block in the device. The positioning block is made of cemented carbide material with a hardness of HRC60-65. It can accurately locate the position of the battery when the battery contacts the discharge pin to ensure the accuracy and consistency of each contact. The controller box and guide rails for the battery docking are fixed by quick clamps.

[0054] Step 4: Before testing, you can enter the product model and SN code to record the data of this model and this batch of batteries. The backend is connected to the MES system of the production line, and the relevant data is synchronously uploaded to the test record before the product is shipped. It can be used to trace problems such as connector wear and poor contact in the later market.

[0055] Step 5: Use a counter that can count up to tens of thousands of times. It can automatically increase once each time the battery contacts the battery compartment. At the end of the test, the counter count is equal to the set test number, thereby automatically counting the test times, saving time and reducing errors.

[0056] Step 6: Set the screen. This is a touch-screen editable screen. The number, frequency and strength of the docking test can be set on the screen. The screen can display the real-time number, which is convenient for operators to adjust according to actual needs.

[0057] Step 7: Distinguish between production line detection mode and aging life mode through the software interface; Step 8: Production line detection mode, perform 10 plug-in tests. After each successful docking, pause for 5 seconds through program control. The communication module in the host is connected to the communication PIN of the connector. The built-in software reads the battery data to determine whether the communication PIN has problems such as cold soldering and poor contact caused by excessive tolerance of the connector size. The voltage measurement module in the host is connected to the positive and negative poles of the connector. The built-in software determines the size of the read discharge port voltage data to determine whether the positive and negative PINs have problems such as cold soldering and poor contact caused by excessive tolerance of the connector size. The next docking test is automatically performed after 5 seconds. A total of 10 tests are performed and 10 data records are recorded. After the test is completed, the host uploads the product model, SN and corresponding test results to the production MES system through the communication of the MES system, which is used to trace the factory data of subsequent product market problems; Step 9: Aging life mode, a total of 5000 docking tests are performed, the frequency is set to 0.5Hz, after the test is completed, check whether the connector and the guide rail have wear, deformation and cracks, whether the host can read data normally through the communication PIN, and whether the correct voltage value can be measured through the positive and negative PINs.
