Description

Technical Field

[0001] This invention relates to the field of lithium battery testing fixture technology, specifically to a convenient lithium battery testing fixture. Background Technology

[0002] As a key energy component widely used in electric vehicles, energy storage systems, and consumer electronics, lithium batteries directly affect the quality and reliability of end products due to their performance and safety. Therefore, during the production of lithium batteries, they must undergo rigorous performance testing and safety assessment, including voltage, current, internal resistance, cycle life, and safety limit testing. As a key interface connecting the battery and the testing equipment, the rationality of the design of the testing fixture directly affects the testing efficiency, accuracy, and ease of operation.

[0003] Currently, most lithium battery testing fixtures on the market adopt a rigid design of "one cell, one fixture". This means that a dedicated fixture and electrical interface are designed for a specific model or size of battery. Such fixtures usually have a fixed structure and a single electrical connection method, which cannot flexibly adapt to batteries of different sizes, electrode layouts or test items. When the production line needs to change the battery model or adjust the test station layout, it is often necessary to replace the entire fixture or perform complex rewiring, resulting in long production downtime, high conversion costs, and seriously affecting production flexibility and efficiency.

[0004] Furthermore, traditional clamps often employ purely rigid clamping or simple sponge pad cushioning for battery fixation: rigid clamping can easily cause mechanical damage to the battery casing, affecting the battery's appearance and even its internal structure; while simple sponge pad cushioning provides insufficient fixing force, making it prone to displacement or loosening during battery transport or dynamic testing, affecting test stability and safety. At the same time, existing tooling often struggles to meet both comprehensive protection and local testing needs on the same equipment. For example, when performing physical safety tests such as needle penetration and compression, it is necessary to disassemble part of the protective structure, which is cumbersome and poses safety hazards.

[0005] In summary, existing lithium battery testing fixtures have significant shortcomings in terms of adaptability, flexibility, ease of operation, and test compatibility, making it difficult to meet the development needs of diversified lithium battery products, stringent testing items, and flexible production lines. Therefore, there is an urgent need for an intelligent testing fixture that can adapt to different battery specifications, flexibly configure test circuits, achieve reliable and non-destructive fixation, and take into account both protection and test accessibility, so as to improve the overall efficiency and intelligence level of the testing line. Summary of the Invention

[0006] The purpose of this invention is to provide a convenient lithium battery testing fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A convenient lithium battery testing fixture includes a placement component, a power-on component, and a docking component. The placement component houses a lithium battery, with a contact head positioned at the top outer end of the battery. The power-on component includes a power box, a sliding seat at the bottom outer end of the power box, and a connection seat at the outer end of the power box. An input terminal is located inside the power box, with a connection wire connected to its outer end. The other end of the connection wire is connected to an output terminal, with an output wire connected to its outer end. The docking component includes a motor, with a lead screw at the motor's output end and a sliding rod at the lead screw's outer end. Electromagnets are mounted at both ends of the sliding rod, and a docking seat is positioned at the outer end of the sliding rod. A docking plug is positioned at the top outer end of the docking seat. A positioning component is located inside the placement component.

[0008] Furthermore, the placement component includes a placement box, a pad is placed at the bottom of the placement box, a sliding rail is provided inside the placement box, and a partition is placed in the middle of the placement box.

[0009] Furthermore, the sliding seat slides via a sliding rail, and the contact head is electrically connected to the connecting seat.

[0010] Furthermore, the pass connector is electrically connected to the pass line via an input terminal, and the pass line is electrically connected to the output line via an output terminal.

[0011] Furthermore, the output line is spiral-shaped and electrically connected to the docking plug via a docking seat.

[0012] Furthermore, the interior of the placement box is equipped with a compression block, which is electromagnetically attracted to the electromagnet.

[0013] Furthermore, the positioning component includes a compression airbag, the outer end of which is provided with a one-way air inlet valve and a one-way air delivery pipe connected to the outer end of the compression airbag. The end of the one-way air delivery pipe is connected to a buffer airbag, and a pressure relief valve is installed at the bottom outer end of the buffer airbag. The outer end of the compression airbag is connected to a one-way air suction pipe, and the end of the one-way air suction pipe is connected to a suction cup. A wind speed sensor is installed at the middle end of the one-way air suction pipe.

[0014] Furthermore, the suction cup is adsorbed and fixed to the lithium battery, and the buffer airbag is attached to the outer surface of the lithium battery.

[0015] Furthermore, the displacement of the compression block compresses the compression airbag, and the compression airbag is connected to the outside world through a one-way air inlet valve.

[0016] Furthermore, the interior of the placement box is fitted with an insertion cover plate, and the outer end of the insertion cover plate is fitted with a displacement handle. Beneficial effects

[0017] 1. This invention enables flexible switching of internal circuit configurations, allowing the equipment to adapt to the specific requirements of measurement points for different test modes such as voltage, current, and charge / discharge. Traditional equipment typically uses a rigid design with one cell and one fixture, and its electrical interface and mechanical position are unchangeable. When the battery model is changed or the test station layout is adjusted, the entire fixture must be replaced or complex rewiring must be performed, resulting in long downtime and high conversion costs. This invention achieves universal docking between the front end and the battery through a sliding power-conducting component 4 and flexible configuration of test signals through internal multi-path circuits. In conjunction with the docking component 5 driven by motor 501, the position of the end test plug is adaptively adjusted, enabling the equipment to quickly adapt to lithium batteries 2 of different sizes and electrode layouts, and actively match the interface positions of various test instruments fixedly installed upstream and downstream of the production line. This achieves a fundamental shift from equipment adapting to tooling to tooling actively adapting to equipment and products, greatly improving the flexibility, intelligence level and overall production efficiency of the test line.

[0018] 2. This invention combines vacuum adsorption with airbag cushioning and rigid limiting to enable the device to achieve self-adaptive and damage-free reliable fixation. In addition, the sliding insert cover can effectively resolve the contradiction between protection and test accessibility. When lithium batteries need to undergo physical safety experiments that require direct contact with the battery body, such as pressure testing and nail penetration testing, the test area can be exposed simply by quickly sliding out the insert cover without complicated disassembly. This allows the device to seamlessly switch between full protection mode and local testing mode on the same fixture, ensuring the safety and stability of the testing process, and greatly improving the compatibility and ease of operation for various test items, thus meeting the diverse and stringent testing needs of lithium batteries.

[0019] 3. In this invention, when the sliding rod is displaced, the electromagnet is energized and attracts the compression block, allowing the compression block to move synchronously with the sliding rod. During this movement, the compression block compresses the compression airbag. When the airbag is compressed, the gas inside is introduced into the buffer airbag through a one-way gas inlet pipe. If the buffer airbag is not full of gas, this operation ensures that the gas inside the buffer airbag is filled, guaranteeing its buffering effect on the lithium battery. If the buffer airbag is full of gas, the pressure inside the buffer airbag will rise when gas is introduced. Excess gas in the buffer airbag can then be discharged through the pressure relief valve. When the sliding rod returns to its original position, the electromagnet... The iron will cause the extrusion block to move away from the extrusion airbag. During the resetting process of the extrusion airbag, air can be drawn in through the one-way air inlet valve and the one-way air suction pipe. The one-way air suction pipe is connected to the suction cup, which allows the equipment to evacuate the air inside the suction cup to ensure the stability of the suction cup's adsorption of the lithium battery. In addition, during the switching of lithium batteries between workstations, the equipment moves the sliding rod back and forth to reciprocate the extrusion block to extrude the airbag. The equipment can determine whether there is a leak in the buffer airbag by judging whether the pressure relief valve has discharged air, and whether the wind speed sensor has sensed the airflow to judge whether the suction cup is firmly adsorbed to the lithium battery. Through the above design, the equipment can determine whether the lithium battery is fixed and stable without interrupting the detection. Attached Figure Description

[0023] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0024] 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 application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0025] Please see Figures 1 to 10 The present invention provides a convenient lithium battery testing fixture, comprising a placement component 1, a power supply component 4, and a docking component 5. The placement component 1 includes a placement box 101, a pad 102 is placed at the bottom of the placement box 101, a sliding rail 103 is provided inside the placement box 101, a partition 104 is placed in the middle of the placement box 101, a lithium battery 2 is placed inside the placement component 1, and a pair of contact heads 3 are placed at the top outer end of the lithium battery 2. The power supply component 4 is placed inside the placement component 1.

[0026] In some embodiments, the power supply assembly 4 includes a power supply box 401, a sliding seat 402 is disposed at the bottom outer end of the power supply box 401, and a connection seat 403 is disposed at the outer end of the power supply box 401. An input terminal 404 is disposed inside the power supply box 401, and a connection line 405 is connected to the outer end of the input terminal 404. The other end of the connection line 405 is connected to an output terminal 406, and an output line 407 is connected to the outer end of the output terminal 406. A docking assembly 5 is disposed on the top inner side of the mounting assembly 1.

[0027] The docking assembly 5 includes a motor 501, with a lead screw 502 at the output end of the motor 501. A sliding rod 503 is mounted on the outer end of the lead screw 502. Electromagnets 504 are mounted on both ends of the outer side of the sliding rod 503. A docking seat 505 is mounted on the outer end of the sliding rod 503. A docking plug 506 is mounted on the top outer end of the docking seat 505. The sliding seat 402 slides via a sliding rail 103 and is electrically connected to the contact head 3 and the docking seat 403. The docking seat 403 is electrically connected to the connection line 405 via an input end 404. The connection line 405 is electrically connected to the output line 407 via an output end. The output line 407 is spiral-shaped and is electrically connected to the docking plug 506 via the docking seat 505. A pressing block 6 is installed inside the placement box 101, and the pressing block 6 is electromagnetically attracted to the electromagnet 504. An insertion cover plate 9 is installed inside the placement box 101, and a displacement handle 8 is mounted on the outer end of the insertion cover plate 9.

[0028] The specific operation is as follows: The operator places the lithium battery 2 to be tested on top of the pad 102 inside the placement box 101. By manually pushing the power supply box 401, the sliding seat 402 at its bottom can slide horizontally along the sliding rail 103 fixed inside the placement box 101 until the connecting seat 403 on the side of the power supply box 401 and the contact head 3 on the top of the lithium battery 2 achieve physical docking and electrical connection. The power supply box 401 integrates four independent input terminals 404 and output terminals 406. Each input terminal 404 is selectively connected to four different output terminals 406 through four independent branch connecting lines 405. The output terminal 406 is connected to the docking seat 505 through the output line 407. The docking seat 505 is fixed to the motor 501 and the lead screw 502. The precision linear drive module, consisting of the sliding rod 503, can drive the docking seat 505 and its top docking plug 506 to make precise displacement in three-dimensional space by controlling the forward and reverse rotation of the motor 501. Since the output line 407 is spiral, it has good extensibility. Since the lithium battery 2 is usually tested using a four-wire system (Kelvin connection), the above design allows for flexible switching of the internal circuit configuration, enabling the equipment to adapt to the specific requirements of the measurement points for different test modes such as voltage, current, and charging and discharging. Traditional equipment usually adopts a rigid design of one cell and one fixture, and its electrical interface and mechanical position are not changeable. When the battery model is changed or the test station layout is adjusted, the entire fixture must be replaced or complex rewiring must be performed, resulting in long downtime and high conversion costs.

[0029] It is understood that the present invention achieves universal docking between the front end and the battery through the sliding power-conducting component 4 and flexible configuration of test signals through internal multi-path circuits. In conjunction with the docking component 5 driven by the motor 501, the position of the end test plug is adaptively adjusted, enabling the equipment to quickly adapt to lithium batteries 2 of different sizes and electrode layouts, and actively match the interface positions of various test instruments fixedly installed in the upstream and downstream of the production line. This realizes a fundamental transformation from equipment adapting to tooling to tooling actively adapting to equipment and products, greatly improving the flexibility, intelligence level and overall production efficiency of the test line.

[0030] Please see Figures 1 to 10The positioning component 7 is installed inside the mounting component 1. The positioning component 7 includes a compression airbag 701. The outer end of the compression airbag 701 is provided with a one-way air inlet valve 702, and the outer end of the compression airbag 701 is connected to a one-way air supply pipe 703. The end of the one-way air supply pipe 703 is connected to a buffer airbag 704, and the bottom outer end of the buffer airbag 704 is provided with a pressure relief valve 705. The outer end of the compression airbag 701 is connected to a one-way air intake pipe 706, and the end of the one-way air intake pipe 706 is connected to a suction cup 708. The middle end of the one-way air intake pipe 706 is provided with a wind speed sensor 707. The suction cup 708 is adsorbed and fixed to the lithium battery 2, and the buffer airbag 704 is in contact with the outer surface of the lithium battery 2. The compression block 6 is displaced to compress the compression airbag 701, and the compression airbag 701 is connected to the outside through the one-way air inlet valve 702.

[0031] In this testing fixture, when the lithium battery 2 is placed into the mounting box 101, its outer contour, the inner wall of the mounting box 101, and the partition 104 provide initial physical constraints, achieving basic stable placement. Furthermore, the bottom of the lithium battery 2 forms a vacuum adsorption with the suction cup 708 pre-set inside the mounting box 101, while its sides are fully fitted with the buffer airbags 704 in the positioning assembly 7. Thus, the device provides a composite fixing solution for the lithium battery 2, combining rigid constraint with bottom adsorption and side airbag cushioning. This solution effectively suppresses the leakage of the lithium battery 2 during the testing process, especially during movement between different workstations or dynamic testing. Vibration, sliding, or accidental tipping fundamentally avoids damage to the battery's appearance or internal structure caused by mechanical displacement. To further enhance protection, after the lithium battery 2 is placed, the operator holds the displacement handle 8 and inserts the insertion cover 9 along the guide rail into the top of the placement box 101. The insertion cover 9 can accurately cover the exposed area above the lithium battery 2, forming a complete protective cavity, thus providing comprehensive physical protection for the battery during routine testing. Because common test fixtures on the market usually use pure rigid clamping or simple sponge pad cushioning, the former is prone to damaging the battery casing, while the latter has insufficient fixing force and is difficult to adapt to different sizes.

[0032] Therefore, by combining vacuum adsorption with airbag buffering and rigid limiting, this invention enables the device to achieve self-adaptive and damage-free reliable fixation. In addition, the sliding insert cover 9 can effectively solve the contradiction between protection and test accessibility. For example, when the lithium battery 2 needs to undergo physical safety experiments that require direct contact with the battery body, such as pressure testing or nail penetration testing, the test area can be exposed simply by quickly sliding out the insert cover 9 without complicated disassembly. This allows the device to seamlessly switch between full protection mode and partial testing mode on the same fixture, ensuring the safety and stability of the testing process, and greatly improving the compatibility and ease of operation for various test items, thus meeting the diverse and stringent testing needs of the lithium battery 2.

[0033] Furthermore, during operation, when the sliding rod 503 is displaced, the electromagnet 504 is energized to attract the compression block 6. This allows the compression block 6 to move synchronously with the sliding rod 503. During this movement, the compression block 6 compresses the compression airbag 701. When the compression airbag 701 is compressed, the gas inside it is introduced into the buffer airbag 704 through the one-way gas supply pipe 703. If the buffer airbag 704 is not fully filled with gas, this operation allows it to be filled with gas to ensure its buffering effect on the lithium battery 2. If the buffer airbag 704 is fully filled with gas, the pressure inside it will rise during gas injection. Excess gas in the buffer airbag 704 can then be discharged through the pressure relief valve 705. When the sliding rod 503 resets, the electromagnet... Magnet 504 will drive the squeezing block 6 to move away from the squeezing airbag 701. During the reset process of the squeezing airbag 701, air can be drawn in through the one-way air inlet valve 702 and the one-way air suction pipe 706. The one-way air suction pipe 706 is connected to the suction cup 708, which allows the equipment to evacuate the air inside the suction cup 708 to ensure the adsorption stability of the suction cup 708 on the lithium battery 2. In addition, during the switching process of the lithium battery 2 between workstations, the equipment moves the sliding rod 503 back and forth to make the squeezing block 6 repeatedly squeeze the airbag 701. The equipment can determine whether there is a leak in the buffer airbag 704 by judging whether the pressure relief valve 705 discharges air and whether the wind speed sensor 707 senses the airflow to determine whether the suction cup 708 is firmly adsorbed on the lithium battery 2. Through the above design, the equipment can determine whether the lithium battery 2 is fixed and stable without interrupting the detection.

[0034] In summary, when using this lithium battery testing fixture, the operator first places the lithium battery 2 to be tested on top of the pad 102 inside the mounting box 101. By manually pushing the power supply box 401, the sliding seat 402 at its bottom can slide horizontally along the sliding rail 103 fixed inside the mounting box 101 until the connecting seat 403 on the side of the power supply box 401 and the contact head 3 on the top of the lithium battery 2 achieve physical docking and electrical connection. The power supply box 401 integrates four independent input terminals 404 and output terminals 406. Each input terminal 404 is selectively connected to four different output terminals 406 through four independent branch connecting lines 405. The output terminal 406 is connected to the docking seat 505 via the output line 407. The docking seat 505 is fixed to the motor 501 and the lead screw 502. The precision linear drive module, consisting of the sliding rod 503, can drive the docking seat 505 and its top docking plug 506 to make precise displacement in three-dimensional space by controlling the forward and reverse rotation of the motor 501. Because the output line 407 is spiral, it has good extensibility. In addition, the sliding power-conducting component 4 enables universal docking between the front end and the battery, and the internal multi-path circuit enables flexible configuration of test signals. In conjunction with the docking component 5 driven by the motor 501, the position of the end test plug can be adaptively adjusted, which enables the equipment to quickly adapt to lithium batteries 2 of different sizes and electrode layouts, and actively match the interface positions of various test instruments fixedly installed in the upstream and downstream of the production line. Next, in this test fixture, after the lithium battery 2 is placed into the placement box 101, its outer contour, the inner wall of the placement box 101, and the partition 104 provide initial physical constraints, achieving basic stable placement. In addition, the bottom of the lithium battery 2 forms a vacuum adsorption with the suction cup 708 preset inside the placement box 101, while its sides are fully attached to the buffer airbags 704 in the positioning component 7. Thus, the device can form a composite fixing scheme for the lithium battery 2, which combines rigid constraint with bottom adsorption and side airbag buffering. This scheme can effectively suppress the movement of the lithium battery 2 during the testing process, especially when it is moved between different workstations or when dynamic testing is performed. The vibration, sliding, or accidental tipping generated during testing fundamentally avoids damage to the battery's appearance or internal structure caused by mechanical displacement. After the lithium battery 2 is placed, the operator holds the displacement handle 8 and inserts the insertion cover 9 along the guide rail into the top of the placement box 101. The insertion cover 9 can accurately cover the exposed area above the lithium battery 2, forming a complete protective cavity, thereby providing comprehensive physical protection for the battery during routine testing. This ensures the safety and stability of the testing process and greatly improves the compatibility and ease of operation for various testing items, meeting the diverse and stringent testing needs of the lithium battery 2. Finally, during the use of the equipment, when the sliding rod 503 is displaced, the electromagnet 504 is energized and attracts the compression block 6. This allows the compression block 6 to move synchronously with the sliding rod 503. During this movement, the compression block 6 compresses the compression airbag 701. When the compression airbag 701 is compressed, the gas inside it is introduced into the buffer airbag 704 through the one-way gas supply pipe 703. If the buffer airbag 704 is not fully filled with gas, this operation allows the gas inside the buffer airbag 704 to be filled, ensuring its buffering effect on the lithium battery 2. If the buffer airbag 704 is fully filled with gas, the pressure inside the buffer airbag 704 will rise when gas is introduced. At this time, excess gas in the buffer airbag 704 can be discharged through the pressure relief valve 705. When the sliding rod 503 resets, the electromagnet... Magnet 504 will drive the squeezing block 6 to move away from the squeezing airbag 701. During the reset process of the squeezing airbag 701, air can be drawn in through the one-way air inlet valve 702 and the one-way air suction pipe 706. The one-way air suction pipe 706 is connected to the suction cup 708, which allows the equipment to evacuate the air inside the suction cup 708 to ensure the adsorption stability of the suction cup 708 on the lithium battery 2. In addition, during the switching process of the lithium battery 2 between workstations, the equipment moves the sliding rod 503 back and forth to make the squeezing block 6 repeatedly squeeze the airbag 701. The equipment can determine whether there is a leak in the buffer airbag 704 by judging whether the pressure relief valve 705 discharges air and whether the wind speed sensor 707 senses the airflow to determine whether the suction cup 708 is firmly adsorbed on the lithium battery 2. Through the above design, the equipment can determine whether the lithium battery 2 is fixed and stable without interrupting the detection.
