Description

Technical Field

[0001] This invention relates to the technical field of battery testing, and in particular to a dual-terminal function testing mechanism for mobile phone batteries. Background Technology

[0002] With the widespread adoption and improved performance of portable electronic devices, especially smartphones, the functional and performance testing requirements for rechargeable batteries, such as lithium-ion batteries, which are their core power source, are becoming increasingly stringent. Battery testing equipment is used to measure and evaluate key parameters of batteries, such as voltage, internal resistance, capacity, and charge / discharge characteristics, and is a crucial piece of equipment for ensuring battery product quality and safety.

[0003] In existing technologies, functional testing of batteries with two independent electrodes faces significant challenges. Most mainstream battery testing equipment is based on a single test interface design, meaning each test station has only one set of test probes or connectors, allowing only one electrical connection to be established with one terminal of the battery at a time for testing. To complete the full testing of both terminals, two series operation modes are commonly used in production practice: first, using two independent single-terminal testing devices sequentially, where the battery completes one terminal test on the first device and is then transferred to the second device for the other terminal test; second, using a complex station switching or rotation mechanism on the same testing equipment to sequentially contact the two terminals of the battery with the same or different test interfaces. Current solutions have the following inherent drawbacks: Whether it's material flow between two machines or workstation switching and repositioning within the same machine, both introduce additional non-testing time, leading to an extended overall production cycle time and making it difficult to meet the high efficiency demands of modern large-scale manufacturing. Using a two-machine solution directly doubles equipment purchase costs, floor space, energy consumption, and maintenance expenses. Even with single-machine time-sharing testing, its mechanical structure and control system are more complex, limiting its cost advantage. Some battery performance tests, such as simulating dynamic response under real load and internal balance characteristics, require simultaneous connection of both terminals to the test circuit. Existing single-terminal sequential testing methods cannot construct such synchronous test conditions, potentially affecting the accuracy of overall battery performance evaluation. Battery terminals are typically space-constrained, requiring extremely high precision in test interface alignment. Existing devices lack effective online, real-time position compensation mechanisms to address battery incoming material position tolerances or mechanical wear during long-term operation, easily leading to poor contact, unstable testing, or damage to expensive test probes and battery terminals. Summary of the Invention

[0004] The main objective of this invention is to provide a dual-terminal functional testing mechanism for mobile phone batteries, aiming to solve the technical problem that existing devices lack an effective online, real-time position compensation mechanism when dealing with battery material position tolerances or mechanism wear during long-term operation, which easily leads to poor contact, unstable testing, or damage to expensive test probes and battery terminals.

[0005] To achieve the above-mentioned objectives, the first aspect of this invention provides a dual-terminal function testing mechanism for a mobile phone battery, comprising: The test module includes a first test board for electrical connection to a first terminal of the battery and a second test board for electrical connection to a second terminal of the battery. A correction drive assembly is connected to the first test board and is used to drive the first test board to move relative to the second test board in order to adjust the docking position between the first test board and the first terminal. A probe assembly includes a test probe and a first drive member, the first drive member being used to drive the test probe to move so that the test probe can simultaneously make electrical contact with exposed contacts on a first test board and a second test board.

[0006] Optionally, the correction drive component includes an XYR rotary correction platform, and the first test board is mounted on the XYR rotary correction platform.

[0007] Optionally, the correction drive assembly further includes a first mounting block for mounting the first test board and a second mounting block for mounting the second test board, wherein the first mounting block is disposed on the XYR rotary correction platform.

[0008] Optionally, the correction drive assembly is driven to the second test board and is used to drive the second test board to move relative to the first test board in order to adjust the docking position between the second test board and the second terminal.

[0009] Optionally, it also includes a lifting trip assembly, which includes a second drive member and a lifting connecting plate mounted on the second drive member. The second drive member is used to drive the lifting connecting plate toward the battery to lift the battery that has completed the test away from the first test plate and the second test plate.

[0010] Optionally, the lifting release assembly further includes a lifting plate and an elastic element disposed between the lifting connecting plate and the lifting plate, and the lifting plate is fixedly connected to the elastic element by fixing screws.

[0011] Optionally, the probe assembly further includes a probe placement plate, a shift stage fixing plate, and a probe connecting plate. The test probe is mounted on the probe placement plate, the first driving component is fixedly mounted on the probe connecting plate, the output end of the first driving component is fixedly connected to the plate body of the probe placement plate, and the probe connecting plate is fixedly connected to the shift stage fixing plate.

[0012] Optionally, the system also includes a robot for transporting the battery to a position where it engages with the first test plate and the second test plate.

[0013] Optionally, it also includes a functional test platform for placing the battery to be tested, and the robot is used to pick up the battery from the functional test platform.

[0014] Optionally, it also includes a visual positioning system, which includes a first camera for taking pictures of the first and second terminals on the battery and a second camera for taking pictures of the first and second test boards.

[0015] Beneficial effects: 1. The dual-terminal functional testing mechanism for mobile phone batteries of the present invention integrates a test module comprising a first test board and a second test board, along with a correction drive component capable of driving at least one of the test boards for fine-tuning of its position, and a probe component capable of simultaneously contacting the exposed contacts of both test boards. This integrates the positioning, alignment, electrical connection, and testing functions of the dual terminals of the battery into a compact workstation. It eliminates the traditional method of requiring two separate devices for step-by-step testing, merging two independent test cycles into one, thus shortening the single test cycle by approximately 50% and significantly improving production speed. Simultaneously, the number of devices, floor space, energy consumption, and maintenance requirements are all halved, thereby significantly reducing manufacturing and operating costs.

[0016] 2. The dual-terminal functional testing mechanism for mobile phone batteries of the present invention, by employing a correction drive component including an XYR rotation correction platform and combining it with real-time feedback from a vision positioning system, can automatically compensate for multi-dimensional positional deviations caused by battery material tolerances, handling and positioning errors, and assembly errors of the mechanism itself. This ensures that even batteries with slight positional fluctuations can achieve precise and reliable physical engagement and electrical contact between their dual terminals and the corresponding test board interface, fundamentally avoiding problems such as test failures, poor contact, or terminal damage caused by misalignment, thus effectively guaranteeing test success rate and product yield.

[0017] 3. The dual-terminal function testing mechanism for mobile phone batteries of the present invention, by setting up a lifting and tripping assembly including an elastic element, gently and evenly lifts the battery off the test plate after the test is completed. The elastic element effectively absorbs the instantaneous impact force during the lifting process, avoiding damage to the battery casing, terminal deformation, or internal cell damage that may be caused by rigid pushing, ensuring the safety of the product during the testing process, and reducing the possibility of quality risks introduced by the testing operation itself.

[0018] 4. The dual-terminal functional testing mechanism for mobile phone batteries of the present invention adopts a modular design for the test board, facilitating rapid replacement to adapt to the terminal specifications and layouts of different battery models. Furthermore, the basic unit of this testing mechanism can be designed in a multi-channel parallel mode, that is, multiple independent testing stations are arranged within the same equipment frame, with one or more robots working collaboratively, thereby achieving a linear increase in production capacity. This allows the present invention to flexibly respond to the needs of future product iterations and changes in production capacity, extending the technical life cycle of the equipment.

[0025] Reference Figures 1-7An embodiment of the present invention provides an embodiment of a dual-terminal function testing mechanism for a mobile phone battery 10, including a test module 100, which includes a first test board 110 for electrically connecting to a first terminal 11 of the battery 10 and a second test board 120 for electrically connecting to a second terminal 12 of the battery 10; a correction drive assembly 200 is drivenly connected to the first test board 110 and is used to drive the first test board 110 to move relative to the second test board 120 to adjust the docking position of the first test board 110 and the first terminal 11; a probe assembly 300 includes a test probe 310 and a first drive member 320, the first drive member 320 being used to drive the test probe 310 to move so that the test probe 310 can simultaneously make electrical contact with exposed contacts on the first test board 110 and the second test board 120.

[0026] Understandably, the test module 100 is the part that directly interacts with the battery 10. Its first test board 110 and second test board 120 are respectively used to connect to the first terminal 11 and the second terminal 12 of the battery 10, forming the physical basis for dual-channel synchronous testing. The role of the correction drive component 200 is crucial. It drives the first test board 110 to make fine-tuning adjustments to compensate for the terminal position deviations generated during the battery 10's arrival or positioning process, ensuring that the two test boards can simultaneously and accurately achieve physical engagement and electrical contact with the corresponding battery 10 terminals. This design directly solves the technical problem of "misalignment" caused by the compact space of the battery 10's two terminals and the possible tolerances in their relative positions. The first drive component 320 drives the test probe 310 to press down, so that it simultaneously contacts the exposed contacts on the first test board 110 and the second test board 120 (usually the test points that conduct electricity after engaging with the battery 10 terminals), thereby simultaneously introducing the test signal into the dual-terminal circuit to complete the overall functional testing of the battery 10 (such as voltage, internal resistance, load characteristics, etc.). This avoids the time required for handling and repeated positioning during step-by-step testing, compressing the testing cycle into a single action.

[0027] The first test board 110 and the second test board 120 are electrically isolated from each other and are connected to the ports of subsequent test instruments through independent internal circuits (not shown in the figure, such as PCB traces or wires), thereby enabling independent or synchronous acquisition and application of signals from the two terminals of the battery 10. To ensure the quality of the test signals, the test board material should preferably be a circuit board substrate such as FR4, and the connector contacts should have good wear resistance and conductivity.

[0028] In a preferred embodiment, the correction drive component 200 specifically employs an XYR rotary correction platform 210. A first test plate 110 is mounted on this platform. The XYR platform provides precise translation in two vertical directions (X and Y) within the horizontal plane, as well as precise movement around an axis perpendicular to the horizontal plane (R direction, i.e., rotation). This allows the first test plate 110 to flexibly compensate for any linear offset and angular deviation in the plane between itself and the second test plate 120, achieving multi-dimensional precise alignment. Using a mature commercial high-precision displacement stage as the XYR platform helps ensure reliability and reduces the difficulty of self-manufacturing. It is important to note that during installation and debugging, the zero point of the XYR platform's movement must be accurately calibrated with the coordinate zero point of the vision system; otherwise, systematic errors will occur in the correction calculation.

[0029] To further optimize the structure and facilitate installation and maintenance, the web guiding drive assembly 200 is also equipped with a first mounting block 220 and a second mounting block 230. The first test plate 110 is mounted on the XYR rotary web guiding platform 210 via the first mounting block 220, while the second test plate 120 is fixed to the mechanism base (frame not shown in the figure) via the second mounting block 230. This makes the replacement of the test plates (e.g., to adapt to different battery models 10) very convenient, requiring only the removal of fasteners on the mounting blocks without disturbing the precision web guiding platform itself. The relative positions of the first mounting block 220 and the second mounting block 230 need to be precisely calibrated using a fixture during initial assembly to ensure the accuracy of the reference.

[0030] In some embodiments, the correction drive component 200 is connected to the second test plate 120 and is used to drive the second test plate 120 to move. The correction drive component 200 drives the first test plate 110 to move. As another layout strategy with functional equivalence, the correction drive component 200 can also be selected to be connected to the second test plate 120 to drive the second test plate 120 to move, while the first test plate 110 remains fixed. This allows for adjustment of the relative position of the two test plates, and its technical effect is equivalent to driving the first test plate 110. The choice of which test plate to drive can be optimized based on factors such as the spatial layout of the overall mechanism, the convenience of cable management (test plates are usually connected to test cables), and the movement path of the robot 500.

[0031] In some embodiments, a lifting tripping assembly 400 is further included, which includes a second drive member 420 and a lifting connecting plate 410 mounted on the second drive member 420. The second drive member 420 is used to drive the lifting connecting plate 410 toward the battery 10 so as to push the battery 10, which has completed the test, away from the first test plate 110 and the second test plate 120.

[0032] Understandably, after testing, there is usually a certain insertion / removal force or friction between the terminals of battery 10 and the terminals of the test board. To ensure that battery 10 can be removed smoothly and without damage, the mechanism preferably also includes a lifting release assembly 400. The second drive member 420 (usually a cylinder) of this assembly drives the lifting connecting plate 410 upward (i.e., toward the battery 10). The lifting connecting plate 410 contacts the non-terminal area of ​​battery 10 (as shown in the lower housing), providing a uniform lifting force to lift battery 10 as a whole, causing its first terminal 11 and second terminal 12 to simultaneously separate from the interfaces of the first test board 110 and the second test board 120. This process achieves automated release, avoiding terminal damage that may be caused by the robot 500 forcibly pulling, and ensuring the stability of the production cycle.

[0033] In some embodiments, the lifting release assembly 400 further includes a lifting plate 440 and an elastic member 430 disposed between the lifting connecting plate 410 and the lifting plate 440, and the lifting plate 440 is fixedly connected to the elastic member 430 by a fixing screw 450.

[0034] Understandably, to ensure a smooth lifting process without impact on the battery 10, the lifting trip assembly 400 incorporates an elastic element 430 (as shown in the attached diagram) between the lifting connecting plate 410 and the lifting plate 440, which directly contacts the battery 10. The lifting plate 440 is connected to the end of the elastic element 430 via a fixing screw 450. When the second drive member 420 pushes the lifting connecting plate 410 upward, the force is transmitted to the lifting plate 440 through the elastic element 430. The elastic element 430 absorbs the instantaneous impact when the drive member starts and provides a certain buffer stroke after the lifting plate 440 contacts the battery 10, ensuring a gentle lifting force and protecting the battery 10 casing. The elastic element 430 is not limited to a pressure spring and can be replaced with other components with similar compressive elasticity, such as elastic pads or silicone pillars. During assembly, care must be taken to ensure that the pre-compression and stiffness of each elastic element 430 are consistent to prevent the lifting plate 440 from tilting.

[0035] In some embodiments, the probe assembly 300 further includes a probe placement plate 330, a shift stage fixing plate 340, and a probe connection plate 350. The test probe 310 is mounted on the probe placement plate 330, the first drive 320 is fixedly mounted on the probe connection plate 350, the output end of the first drive 320 is fixedly connected to the plate body of the probe placement plate 330, and the probe connection plate 350 is fixedly connected to the shift stage fixing plate 340.

[0036] Understandably, test probes 310 are mounted on a probe placement plate 330 to achieve synchronous installation and positioning of multiple probes. Test probes 310 are typically high-frequency or high-current probes. A first driving component 320 (typically a cylinder) is fixed to a probe connecting plate 350, with its piston rod end fixedly connected to the plate body of the probe placement plate 330, thereby driving the entire probe placement plate 330 and all test probes 310 to rise and fall together. The probe connecting plate 350 is fixed to a high-rigidity shifting stage fixing plate 340, providing a stable reference for the movement of the entire probe assembly 300. This ensures simultaneous contact and disengagement of all test probes 310, resulting in excellent test signal synchronization. In actual debugging, the height of the probe placement plate 330 needs to be precisely adjusted to ensure reliable contact without excessive compression when the test probes 310 are pressed into place, thus extending probe lifespan.

[0037] To achieve a fully automated process, the mechanism also includes a robot 500 (such as a six-axis robot or a SCARA robot). This robot 500 is responsible for gripping, transporting, and precisely placing the battery 10. Its end effector, typically a vacuum suction cup or a custom gripper, transports the battery 10 to a pre-set testing station and controls the battery 10 to be pressed down in the correct posture and position, ensuring its two terminals are initially aligned with the first test plate 110 and the second test plate 120 below. The participation of the robot 500 ensures seamless integration of loading / unloading with the testing process, a key factor in improving overall production efficiency. The accuracy of the robot 500's motion trajectory directly affects the accuracy of the initial alignment, thus influencing the magnitude of subsequent correction compensation.

[0038] Furthermore, in conjunction with robot 500, a functional testing platform 600 is set up to centrally hold the batteries 10 to be tested. This platform can be designed as a positioning station on an assembly line or a multi-station turntable. Robot 500 picks up the battery 10 from the functional testing platform 600, and after testing, returns the battery 10 to the platform or moves it to the next process. This optimizes the material flow path, allowing the testing mechanism to be easily integrated into an automated production line. The functional testing platform 600 is typically equipped with positioning fixtures to initially constrain the position of the battery 10, reducing posture deviations during robot 500's grasping.

[0039] In some embodiments, a visual positioning system is also included, comprising a first camera 710 for taking pictures of the first terminal 11 and the second terminal 12 on the battery 10, and a second camera 720 for taking pictures of the first test board 110 and the second test board 120.

[0040] Understandably, the visual positioning system includes a first camera 710 (such as...) Figure 1 (mid-range dual-terminal vision imaging) and second camera 720 (e.g.) Figure 1(Visual imaging on the test board). The first camera 710 takes pictures of the battery 10, which is transported to the imaging station by the robot 500, from below (or diagonally below), accurately identifying and calculating the actual positions of its first terminal 11 and second terminal 12 in the mechanism coordinate system. At the same time or shortly thereafter, the second camera 720 takes pictures of the reference features (such as specific markings or interface contours) of the first test board 110 and the second test board 120, which are already installed on the test station, for positioning. The control system compares the two sets of position data and calculates the positional deviation (including X, Y, and R deviations) between the battery 10 terminals and the corresponding test board interfaces. Subsequently, this deviation data is sent to the correction drive assembly 200 (i.e., the XYR rotation correction platform 210) to drive the first test board 110 to move for compensation. This effectively overcomes interference factors such as incoming material errors, robot 500 repetitive positioning errors, and mechanism thermal deformation, and is the core guarantee for achieving high success rate and high reliability testing. The first camera 710 and the second camera 720 are usually fixed-focal-length industrial area array CCD or CMOS cameras, paired with telecentric lenses to reduce perspective errors.

[0041] In summary, the XYR rotary correction platform 210 can be a three-axis integrated precision motion platform, driven by three servo motors or stepper motors in conjunction with ball screws (for the X and Y axes) and a precision rotary axis (for the R axis). The first mounting block 220 acts as an adapter, fastened to the mover disk of the XYR rotary correction platform 210 with bolts. During assembly, a high-precision level must be used to calibrate the mounting base of the XYR rotary correction platform 210 to ensure that its motion plane is parallel to the motion plane of the robot 500 pressing down the battery 10; otherwise, it will introduce angular errors that are difficult to compensate for.

[0042] Its working logic is as follows: After the visual positioning system acquires the deviation data, the control system first performs a coordinate transformation, converting the deviation value into the coordinate system of the XYR rotational correction platform 210 itself. Then, it controls the XYR rotational correction platform 210 to drive the first test board 110 to perform corresponding translational and rotational movements. After the movement is in place, a short position stabilization time (e.g., 100-200 milliseconds) is usually required to eliminate minor vibrations of the platform and ensure the accuracy after alignment and stillness. If the second test board 120 is a movable design, its drive component structure and control logic are the same, but the reference selection is reversed.

[0043] In practical applications, the workflow is briefly described as follows: Robot 500 picks up a battery 10 to be tested from functional testing platform 600 and moves it below the field of view of first camera 710 to take a picture, obtaining the precise position of the two terminals of battery 10. Simultaneously, second camera 720 takes pictures of the first test board 110 and the second test board 120 on test module 100. The control system calculates the deviation between the terminal position of battery 10 and the target position of the test board. Correction drive component 200 drives the first test board 110 to move according to the calculation result, compensating for the positional deviation. Then, robot 500 presses down on battery 10, ensuring that its first terminal 11 and second terminal 12 are precisely engaged with the aligned first test board 110 and second test board 120, respectively. The first drive component 320 of probe assembly 300 actuates, driving test probe 310 to descend, ensuring reliable contact with the exposed contacts on both the first test board 110 and the second test board 120. The tester applies test signals to battery 10 through the probe and test board and collects the response, completing the functional test.

[0044] After the test is completed, the probe assembly 300 first rises and resets. Then, the second drive component 420 of the lifting trip assembly 400 actuates, smoothly lifting the battery 10 through the lifting plate 440, separating its terminals from the test board. Finally, the robot 500 removes the tested battery 10, placing it back into the functional test platform 600 or transferring it to the next workstation, and begins the next cycle.
