Description

Technical Field

[0001] This utility model relates to the field of lithium battery testing technology, specifically a soft-pack lithium battery formation testing device. Background Technology

[0002] In today's rapidly developing new energy industry, pouch lithium batteries have been widely used in electric vehicles, portable electronic devices, and energy storage systems due to their advantages such as high energy density, flexible shape, and relatively good safety. With the explosive growth in market demand for pouch lithium batteries, quality control in their production is crucial, and formation testing, as a key process to ensure the performance and safety of lithium batteries, has received particular attention.

[0003] Traditional pouch lithium battery formation and testing processes have many drawbacks. Early on, lithium battery weight testing relied heavily on manual operation. Workers had to manually weigh each battery on the production line, a method that was not only inefficient and prone to inaccurate results due to human fatigue and operational errors, but also consumed significant manpower and time. Furthermore, if batteries with abnormal weights were found after manual weighing, subsequent sorting also relied on manual picking, further increasing the probability of errors and hindering seamless integration with automated production processes, thus impeding increased production efficiency.

[0004] With technological advancements, semi-automatic testing equipment has gradually entered lithium battery production workshops. However, these devices still have significant shortcomings. On the one hand, while some existing formation testing devices possess certain automated weighing functions, they lack precise comparison and reference mechanisms. They can only display the actual weight of the lithium battery, failing to quickly and intuitively determine whether the weight meets standard production requirements. Operators need to spend extra time comparing complex standard data tables, increasing the difficulty and complexity of judgment and easily leading to misjudgments. On the other hand, when lithium batteries that do not meet weight standards are detected, most devices lack efficient separation and output functions. Often, shutdown or manual intervention is required to separate the defective batteries from the qualified product stream. This not only disrupts production continuity and reduces overall production efficiency but also risks the mixing of defective products with qualified products due to untimely handling, affecting product quality and causing potential economic losses and reputational risks for the company.

[0021] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Please see Figure 1-3 A soft-pack lithium battery formation detection device includes a base plate 1, on which a counterweight balance detection component is provided, and a horizontal limiting component and a separation output component are respectively provided on both sides of the counterweight balance detection component.

[0023] The counterweight balance detection component includes an intermediate frame 2 fixedly mounted on a base plate 1, a rotating column 3 rotatably connected to the intermediate frame 2, a standard platform 4 and a detection platform 5 respectively on both sides of the rotating column 3, a lithium battery sample fixedly placed on the standard platform 4, and an installation rod 6 fixedly connected between the rotating column 3 and the standard platform 4 and the detection platform 5.

[0024] The horizontal limiting component includes a side frame 10 fixedly installed at the top of the base plate 1, an electric telescopic rod 11 fixedly installed on the side frame 10, and a positioning seat 8 fixedly connected to the telescopic end of the electric telescopic rod 11. The positioning seat 8 is located on one side of the standard table 4.

[0025] The separation output assembly includes a conveyor partition 12 fixedly installed at the top of the base plate 1. The conveyor partition 12 is located below the placement groove 17. A first separation conveyor belt 13 and a second separation conveyor belt 14 are respectively provided on both sides of the conveyor.

[0026] The top surface of the testing station 5 is provided with a placement slot 17.

[0027] The side of the conveyor partition 12 is fixedly connected to a conveyor frame 15, and the conveyor frame 15 is equipped with a conveyor motor 16 for driving the first separating conveyor belt 13 and the second separating conveyor belt 14.

[0028] Guide side seats 18 are fixedly connected to both sides of the positioning seat 8, and a guide rod 9 is fixedly connected to the side of the side frame 10 near the positioning seat 8. The guide rod 9 passes through the guide side seat 18 and is slidably connected to it.

[0029] A straight clamping plate 19 is fixedly connected to the side of the positioning seat 8 away from the side frame 10. An open clamping plate 20 is fixedly connected to the end of the straight clamping plate 19 away from the positioning seat 8. The straight clamping plate 19 has a straight clamping groove, and the open clamping plate 20 has an open clamping groove.

[0030] In the implementation of this utility model, the lithium battery sample 7 is always fixed on the standard platform 4. When the weight of the produced lithium battery is tested, the lithium battery to be tested is placed in the middle of the placement slot 17. At this time, since one end of the standard platform 4 is located in the straight clamp 19, under the restriction of the positioning seat 8 and the straight clamp 19, both the standard platform 4 and the testing platform 5 are in a horizontal state.

[0031] Then control the electric telescopic rod 11 to retract, driving the positioning seat 8 to move toward the side frame 10, and the standard table 4 moves out of the straight clamping groove and the open clamping groove, and the standard table 4 loses its restriction;

[0032] If the weight of the lithium battery to be tested on the testing stage 5 is the same as that of the lithium battery sample 7, then the standard stage 4 and the testing stage 5 continue to remain horizontal.

[0033] If the weight of the lithium battery to be tested on the testing platform 5 is greater than the mass of the lithium battery sample 7, the standard platform 4 moves down and the testing platform 5 moves up. Both the standard platform 4 and the testing platform 5 tilt, and the lithium battery to be tested on the testing platform 5 slides from the placement groove 17 onto the second separation conveyor belt 14 and is transported away.

[0034] If the weight of the lithium battery to be tested on the testing platform 5 is less than the mass of the lithium battery sample 7, the standard platform 4 moves up and the testing platform 5 moves down. Both the standard platform 4 and the testing platform 5 tilt, and the lithium battery to be tested on the testing platform 5 slides from the placement groove 17 onto the first separation conveyor belt 13 and is transported away.

[0035] By observing the position and status of the testing station 5, one can intuitively determine whether the weight of the lithium battery to be tested meets the standard.

[0036] In addition, in order to ensure that the qualified weight of the lithium battery to be tested is within a certain range, a friction ring can be set at the connection between the rotating column 3 and the intermediate frame 2 to increase the friction between the rotating column 3 and the intermediate frame 2. This method can ensure that the weight difference between the lithium battery to be tested and the lithium battery sample 7 is within the allowable range, thus ensuring that the testing platform 5 and the standard platform 4 are in a balanced state. The lithium battery to be tested in a balanced state is a product with qualified weight.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
