Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a battery testing station. Background Technology

[0002] Battery testing is a crucial step in battery production and use, aiming to ensure that battery performance and safety meet relevant standards. Traditional battery testing methods typically rely on manual operation, involving manually bringing testing equipment into contact with the battery electrodes. However, this method suffers from low efficiency, inconsistent testing accuracy, and high labor intensity for operators. Furthermore, the inherent uncertainties of manual operation can lead to significant errors in test results, affecting the consistency of product quality.

[0003] While existing battery testing equipment on the market has achieved partial automation, it still has some shortcomings in the testing process. For example, the positioning accuracy of the testing equipment is low, making it difficult to ensure precise alignment between the electrode contact head and the battery electrode, which can easily lead to poor contact or test failure. At the same time, existing testing equipment often lacks rapid identification capabilities for battery information, failing to efficiently complete battery identity verification and data recording, thus limiting further improvements in testing efficiency. Furthermore, some equipment has complex structural designs, high maintenance costs, and is prone to mechanical failures during long-term operation, affecting the continuity of the production process.

[0004] Therefore, there is an urgent need for a battery testing device that can improve detection accuracy, simplify operation procedures, and enhance equipment stability to meet the demands of modern industry for efficient and accurate testing. This invention addresses these issues by proposing a battery testing platform with a reasonable structure, convenient operation, and the ability to achieve high-precision testing. It aims to overcome the shortcomings of existing technologies and provide a more reliable solution for battery testing. Utility Model Content

[0005] The purpose of this invention is to provide a battery testing station to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A battery testing station includes a workbench on which a screen bracket and a fixed platform are fixedly mounted. The screen bracket supports a display screen, which is connected to a control system to display numerical information acquired during battery testing in real time. The fixed platform is a rectangular metal plate structure with a pair of uprights symmetrically fixed on both sides. The uprights are connected by a top plate to form a stable frame structure. A lifting cylinder is mounted on the top plate. The cylinder body of the lifting cylinder is fixedly connected to the top plate by bolts, and the end of its piston rod is threadedly connected to a sliding plate. The sliding plate is sleeved on the uprights by embedded roller bearings and slides along the uprights, thereby realizing the vertical movement of the sliding plate.

[0008] Furthermore, a reinforcing crossbar is fixedly installed at the bottom of the sliding plate. The reinforcing crossbar is a rectangular metal component, and its length direction is parallel to the sliding plate. A pair of vertically extending extension frames are fixedly installed at the bottom of the reinforcing crossbar. The extension frames are bolted into straight grooves on the reinforcing crossbar. The straight grooves are arranged along the length direction of the reinforcing crossbar, allowing the position of the extension frames to be adjusted according to the specifications of the battery to be tested. Electrode contact heads are provided at the bottom of the extension frames. The electrode contact heads are connected to the extension frames via a spring-loaded mechanism to ensure stable contact between the electrode contact heads and the battery electrodes during testing.

[0009] Specifically, a connecting rod is fixedly installed on one side of the reinforcing crossbar, and the connecting rod is connected to the reinforcing crossbar by welding. A fixing plate is fixedly installed on the other end of the connecting rod. A scanning gun is installed on one side of the fixing plate, and the scanning nozzle of the scanning gun is vertically downward for scanning the marking information on the battery to be tested. The scanning gun is connected to the data acquisition module to transmit the scanned information to the control system, assisting in the recording and analysis of battery test data.

[0010] Furthermore, a positioning block is fixedly installed on the top surface of the fixed platform. The positioning block is a rectangular protrusion with an internal space for accommodating the battery, used to pre-set the position of the battery to be tested. The positioning block is fixed to the surface of the fixed platform with screws, and its position can be adjusted according to actual needs. The height of the positioning block is slightly higher than the surface of the fixed platform to ensure accurate positioning of the battery to be tested during placement.

[0011] The battery testing method of this utility model includes the following steps:

[0012] S1: Place the battery to be tested in the positioning block on the fixed platform to ensure that the battery position is fixed;

[0013] S2: The control system activates the lifting cylinder, driving the sliding plate to move downward along the column, so that the extension frame and the electrode contact head at its bottom descend synchronously;

[0014] S3: The electrode contact head precisely contacts the battery electrode, while the scanner scans the marking information on the battery to complete information acquisition;

[0015] S4: After the test is completed, the lifting cylinder drives the sliding plate to move upward, so that the electrode contact head is separated from the battery electrode, completing one test cycle.

[0016] Furthermore, the lifting cylinder is controlled by a solenoid valve, which is connected to the control system and drives the lifting cylinder to move after receiving a control signal. The sliding plate along the column is achieved by roller bearings, which are installed inside the sliding plate with an interference fit to ensure smooth and wobbly movement of the sliding plate. The adjustment range of the extension frame is 0 to 50 mm to accommodate the testing requirements of batteries of different specifications.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The frame structure, composed of columns, sliding plates, reinforcing crossbars, and connecting rods, enhances the mechanical stability of the entire testing station, preventing testing errors caused by vibration or external forces. The introduction of a lifting cylinder enables automatic raising and lowering of the electrode contact head, reducing manual intervention and improving testing efficiency. The positioning blocks ensure accurate battery positioning during testing, and combined with the information acquisition function of the scanner, further improves testing accuracy. Furthermore, the linear groove design on the reinforcing crossbars allows for flexible adjustment of the extension frame's position, expanding the testing station's applicability and enabling it to meet the testing needs of various battery specifications.

[0019] In particular, this invention solves the problem of poor electrode contact in traditional testing equipment by using a spring-loaded mechanism design for the electrode contact head. Simultaneously, the synchronous operation design of the scanning gun and the electrode contact head ensures consistency between information acquisition and performance testing during the testing process, significantly improving the reliability of the test results.

[0020] In summary, the battery testing station provided by this utility model has the characteristics of compact structure, simple operation and high testing accuracy, and is suitable for automated testing scenarios of various batteries, especially for the high-efficiency testing needs in large-scale production lines.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0029] like Figure 1 As shown, the entire device is based on a workbench 1, on which a screen bracket 2 and a fixed platform 3 are fixedly mounted. The screen bracket 2 is fixedly connected to the workbench 1 by bolts and is used to support the display screen, which is connected to the control system to display the numerical information acquired during battery testing in real time. The fixed platform 3 is a rectangular metal plate structure with a pair of columns 5 symmetrically fixed on both sides. The columns 5 are made of high-strength steel, and their tops are connected by a top plate to form a frame structure to ensure overall stability. A lifting cylinder 6 is installed on the top plate. The cylinder body of the lifting cylinder 6 is fixedly connected to the top plate by bolts, and the end of its piston rod is connected to a sliding plate 7 by threads.

[0030] The sliding plate 7 is a rectangular metal plate structure with embedded roller bearings. These bearings are installed within the sliding plate 7 via an interference fit, ensuring smooth sliding along the column 5. A reinforcing crossbar 9, a rectangular metal component, is fixed to the bottom of the sliding plate 7, its length parallel to the sliding plate 7. A pair of extension frames 10, vertically extending metal rods, are bolted to the bottom of the reinforcing crossbar 9, each with an electrode contact head at its bottom. The electrode contact head is connected to the extension frame 10 via a spring-loaded mechanism, ensuring stable contact between the electrode contact head and the battery electrode during testing. The reinforcing crossbar 9 also features a linear groove along its length, allowing the position of the extension frame 10 to be adjusted from 0 to 50 mm according to the specifications of the battery being tested, thus accommodating the testing needs of different battery sizes.

[0031] Furthermore, a connecting rod 8 is fixedly installed on one side of the reinforcing crossbar 9, and the connecting rod 8 is connected to the reinforcing crossbar 9 by welding. A fixing plate 12 is fixedly installed on the other end of the connecting rod 8. A scanning gun 11 is installed on one side of the fixing plate 12, with the scanning nozzle of the scanning gun 11 pointing vertically downwards, for scanning the marking information on the battery to be tested. The scanning gun 11 is connected to the data acquisition module, transmitting the scanned information to the control system to assist in the recording and analysis of battery test data. A positioning block 4 is fixedly installed on the top surface of the fixing platform 3. The positioning block 4 is a rectangular protrusion structure with a space inside to accommodate the battery, for pre-setting the position of the battery to be tested. The positioning block 4 is fixed to the surface of the fixing platform 3 with screws, and its position can be adjusted according to actual needs. Its height is slightly higher than the surface of the fixing platform 3 to ensure accurate positioning of the battery to be tested when placed.

[0032] During operation, the battery to be tested is first placed in the positioning block 4 on the fixed platform 3 to ensure its fixed position. Then, the control system activates the lifting cylinder 6, driving the sliding plate 7 downwards along the column 5. The movement of the sliding plate 7 is controlled by the lifting cylinder 6, which is connected to the control system via a solenoid valve and receives control signals to drive the lifting cylinder 6. The sliding of the sliding plate 7 along the column 5 is achieved by roller bearings, which are installed within the sliding plate 7 with an interference fit to ensure smooth and stable movement without wobbling. As the sliding plate 7 descends, the extension frame 10 and its bottom electrode contact head descend synchronously until the electrode contact head precisely contacts the battery electrode. Simultaneously, the scanning gun 11 scans the marking information on the battery to complete information acquisition. After the test is completed, the lifting cylinder 6 drives the sliding plate 7 upwards, disengaging the electrode contact head from the battery electrode, completing one test cycle.

[0033] In practical applications, the battery testing station of this invention is suitable for various scenarios, especially performing exceptionally well in meeting the high-efficiency testing needs of large-scale production lines. For example, on a lithium battery production line, operators place batch-produced lithium batteries one by one into the positioning block 4. The height design and internal space constraints of the positioning block 4 ensure that each battery maintains a uniform placement position during testing. Subsequently, the control system automatically activates the lifting cylinder 6, driving the sliding plate 7 to move the extension frame 10 downwards until the electrode contact head contacts the battery electrode. During this process, the spring loading mechanism of the electrode contact head automatically adjusts the contact pressure according to minute deviations on the battery electrode surface, avoiding testing errors caused by poor contact. Simultaneously, the scanner 11 scans the QR code or barcode on the battery to obtain information such as the battery's production batch and model, and uploads this information to the data acquisition module. The data acquisition module associates and stores the scanned information with the testing results, facilitating subsequent data analysis and quality traceability.

[0034] To further improve testing efficiency, this invention also incorporates a linear groove, allowing for flexible adjustment of the extension frame 10's position. For example, when testing batteries of different specifications, operators can loosen bolts to move the extension frame 10 along the linear groove to a suitable position, and then retighten the bolts to secure the extension frame 10. This design significantly expands the applicability of the testing station, enabling it to meet the testing needs of various battery specifications. Furthermore, the introduction of the lifting cylinder 6 enables automatic lifting of the electrode contact head, reducing manual intervention and improving testing efficiency. Throughout the testing process, the control system monitors the operation of the lifting cylinder 6 and the contact status of the electrode contact head in real time, ensuring the stability and reliability of the testing process.

[0035] In terms of mechanical stability, this invention improves the overall mechanical stability of the testing platform through a frame structure composed of a column 5, a sliding plate 7, a reinforcing crossbar 9, and a connecting rod 8. The column 5 is made of high-strength steel, and its connection to the top plate is reinforced by welding, ensuring that the frame structure will not deform or loosen during long-term use. The sliding plate 7 along the column 5 is achieved by roller bearings. The interference fit design of the roller bearings effectively reduces the friction of the sliding plate 7 during movement, extending its service life. The design of the reinforcing crossbar 9 further enhances the rigidity of the sliding plate 7, preventing swaying or displacement caused by external forces. Furthermore, the synchronous operation design of the scanning gun 11 and the electrode contact head ensures the consistency of information acquisition and performance testing during the testing process, significantly improving the reliability of the test results.

[0036] In summary, the battery testing station provided by this utility model solves the problems of complex structure, cumbersome operation, and insufficient testing accuracy in traditional testing equipment by optimizing the mechanical structure, introducing automated control, and flexibly adjusting the design. In practical applications, this testing station can not only meet the high-efficiency testing needs of large-scale production lines, but also adapt to the testing requirements of various battery specifications, demonstrating high practical value and promising prospects for widespread application.

[0037] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
