A side plate is fixedly mounted above the heat dissipation area. A display area is located below the alarm light near the outer wall of the device body. A drive motor drives a drive shaft to move a drive plate up and down along a slide rail within the drive cavity, facilitating vertical alignment of the battery pack and reducing direct manual intervention. The conveying plate can move multiple battery packs to a vertical position on the upper testing plate, facilitating cyclic testing of the battery packs. This enables rapid testing of lithium batteries and improves testing efficiency.
[0004] However, during the feeding process, lithium batteries are prone to positional deviation due to insufficient friction or lack of limiting in the conveying mechanism, resulting in inaccurate detection positions. When unloading lithium batteries after detection, they are prone to scattering or jamming, making it difficult to collect them centrally, increasing the workload of subsequent processing, and affecting detection efficiency and stability. Therefore, those skilled in the art provide a lithium battery detection device to solve the problems mentioned in the background art. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model is equipped with a feeding mechanism. The fixing plate provides stable support for components such as the triangular plate and the stop plate. The transition plate is closely connected to the conveyor belt to achieve a smooth transition of the lithium battery and avoid jamming or falling during transfer.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figures 1-4As shown, this utility model provides a technical solution: a lithium battery testing device, including two sets of symmetrically arranged baffles 1 for preventing the lithium battery from deviating from its position, a feeding mechanism 2 fixedly arranged between the two sets of symmetrically arranged baffles 1, a feeding mechanism 3 for centrally feeding and collecting the tested lithium batteries fixedly arranged at the end of the baffle 1 away from the feeding mechanism 2, a hammer pressing assembly 4 for testing the lithium battery fixedly arranged at the center of the side end of the baffle 1, and a feeding guide plate 5 for guiding the feeding of the lithium battery fixedly connected to the side of the baffle 1 near the feeding mechanism 3.
[0022] Two sets of symmetrically arranged baffles 1 effectively constrain the movement path of lithium batteries, preventing them from deviating from their positions during transportation and testing, and ensuring the accuracy of the testing position. The feeding mechanism 2 enables automatic and continuous transportation of lithium batteries, reducing the tediousness of manual feeding and improving testing efficiency. The unloading mechanism 3 can centrally process and collect the tested lithium batteries, preventing them from scattering and facilitating subsequent unified management. The hammer pressing assembly 4 is precisely installed at the center of the side end of the baffle 1, enabling stable and standardized hammer pressing testing of the lithium batteries transported here, ensuring the reliability of the test results. The unloading guide plate 5 provides guidance for the movement of lithium batteries from the testing area to the unloading mechanism 3, making the unloading process smoother and reducing jamming.
[0023] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the feeding mechanism 2 includes a fixed column 21, which is fixedly connected between two sets of symmetrically arranged baffles 1. One end of the fixed column 21 is fixedly connected to a motor 22, and both ends of the motor 22 are rotatably connected to a rotating shaft 23. The end of the rotating shaft 23 away from the motor 22 is fixedly connected to a driving column 24.
[0024] When motor 22 starts, the power output of motor 22 is transmitted to the rotating shafts 23 at both ends, causing the rotating shafts 23 to rotate. Since the driving column 24 is fixedly connected to the rotating shaft 23, the rotation of the rotating shaft 23 will synchronously drive the driving column 24 to rotate. Throughout the process, the fixed column 21 plays a stable supporting role for motor 22, preventing the motor 22 from shifting its position due to vibration during operation, thereby ensuring the stability of the rotation of the driving column 24 and providing a reliable power foundation for the delivery of lithium batteries.
[0025] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a rubber outer ring for increasing friction is fixedly connected to the outer surface of the drive column 24, and two sets of drive columns 24 with rubber outer rings are symmetrically arranged. The outer surfaces of the two sets of symmetrically arranged drive columns 24 are rotatably connected to a conveyor belt 25.
[0026] When the drive column 24 rotates under the drive of the motor 22 and the rotating shaft 23, the friction generated by the rotation of the drive column 24, due to the close contact between the rubber outer ring on the outer surface of the drive column 24 and the inner surface of the conveyor belt 25 and the large coefficient of friction of the rubber outer ring, will cause the conveyor belt 25 to rotate accordingly. The lithium battery is placed on the conveyor belt 25, and under the action of the friction of the conveyor belt 25, the lithium battery will move together with the conveyor belt 25, thereby realizing the transport from the initial position to the detection area. The two sets of symmetrical drive columns 24 ensure the smooth operation of the conveyor belt 25, avoid problems such as belt deviation, and ensure that the lithium battery moves along the predetermined path.
[0027] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the feeding mechanism 3 includes a fixed plate 31, which is fixedly connected to the end of the baffle 1 away from the feeding mechanism 2. A triangular plate 32 is fixedly connected to the upper end of the fixed plate 31 on one side. A transition plate 33 is fixedly connected to the top of the triangular plate 32, and the end of the transition plate 33 near the feeding mechanism 2 is in close contact with the upper surface of the conveyor belt 25.
[0028] After the lithium battery passes inspection, as the conveyor belt 25 moves to its end, the transition plate 33, located near the upper surface of the conveyor belt 25, smoothly moves from the conveyor belt 25 onto the transition plate 33 due to its own inertia and the pushing force of the conveyor belt 25. The triangular plate 32 supports the transition plate 33, maintaining it at a certain angle. Under gravity, the lithium battery slides down the inclined surface of the transition plate 33, thus entering the subsequent processing area of the unloading mechanism 3.
[0029] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a stop plate 34 is fixedly connected to one side of the upper end of the fixed plate 31, and a rubber layer for increasing friction is fixedly connected to the upper surface of the stop plate 34. A connecting plate 35 is fixedly connected to one end of the fixed plate 31, and a first cylinder 36 is fixedly connected to the upper end of the connecting plate 35. A pusher plate 37 is slidably connected to the inner cavity of one end of the first cylinder 36. A collection frame 38 is fixedly connected to the bottom end of the fixed plate 31.
[0030] The lithium battery sliding down from the transition plate 33 moves to the stop plate 34, where it is stopped. The rubber layer on the stop plate 34 increases the friction between the lithium battery and the stop plate 34, keeping the lithium battery stable in that position. When it is time to unload the lithium battery, the first cylinder 36 is activated, and its internal piston rod extends, pushing the pusher plate 37 connected to it towards the stop plate 34. After the pusher plate 37 contacts the lithium battery, it applies a pushing force to the lithium battery, causing it to overcome the friction of the rubber layer on the stop plate 34 and move, eventually being pushed into the collection frame 38 at the bottom of the fixed plate 31, completing the collection of the lithium battery. Afterward, the piston rod of the first cylinder 36 retracts, driving the pusher plate 37 back to its initial position, waiting for the next pushing operation.
[0031] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the hammer pressing assembly 4 includes a connecting column 41, which is fixedly connected to the center of the side end of the baffle 1. A second cylinder 42 is fixedly connected to the center of the top end of the connecting column 41, and a hammer press 43 is slidably connected to the center of the bottom end of the connecting column 41. The hammer press 43 is slidably connected to the connecting column 41 and the second cylinder 42 through a shaft.
[0032] When the lithium battery is conveyed by the conveyor belt 25 to the detection position directly below the hammer pressing assembly 4, the second cylinder 42 is activated, and its internal piston rod extends downward. Since the hammer pressing device 43 is connected to the piston rod of the second cylinder 42 via a shaft, the extension of the piston rod causes the hammer pressing device 43 to slide downward along the bottom end of the connecting post 41. During the sliding process, the hammer pressing device 43 gradually approaches the lithium battery and eventually applies a certain pressure to the lithium battery to test its performance under pressure. After the test is completed, the piston rod of the second cylinder 42 retracts, causing the hammer pressing device 43 to move upward and return to its initial position, waiting for the next lithium battery to enter the detection position before repeating the hammer pressing action. Throughout the process, the connecting post 41 guides the sliding of the hammer pressing device 43, ensuring that the hammer pressing device 43 can accurately act on the lithium battery.
[0033] Working principle: The lithium battery is placed on the conveyor belt 25 of the feeding mechanism 2. The motor 22 drives the drive column 24 with a rubber outer ring to rotate through the rotating shaft 23. The increased friction of the rubber outer ring drives the conveyor belt 25 to rotate. Under the limiting action of two sets of symmetrical baffles 1, the lithium battery is stably conveyed along the conveyor belt 25. When the lithium battery is conveyed to the center of the side of the baffle 1 below the hammer pressing assembly 4, the second cylinder 42 drives the shaft to drive the hammer pressing device 43 to slide downward to perform hammer pressing test on the lithium battery. The connecting column 41 ensures the movement accuracy of the hammer pressing device 43. After the test is completed, the lithium battery continues to move with the conveyor belt 25 and slides through the transition plate 33 which is in close contact with the conveyor belt 25 to the stop plate 34 of the unloading mechanism 3. The rubber layer on the surface of the stop plate 34 increases friction to make the lithium battery temporarily stable. Subsequently, the first cylinder 36 pushes the pusher plate 37 to push the lithium battery to the unloading guide plate 5. Under the guidance of the unloading guide plate 5, the lithium battery finally falls into the collection frame 38 at the bottom of the fixed plate 31, completing the entire detection and collection process. The coordinated operation of all components realizes the automated operation of lithium battery from conveying and detection to unloading and collection.
