Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lithium battery production and testing equipment, and in particular to a lithium-ion battery production and testing structure. Background Technology
[0002] The lithium-ion battery production testing structure is a quality control system that runs through the entire production process from raw material intake to cell manufacturing, assembly, and finished product delivery. Its core function is to avoid defects at the source, reduce deviations in the process, and ultimately ensure the consistency of battery performance, safety, and lifespan reliability through layered testing and key node control. Essentially, it is to avoid batch quality problems caused by inferior raw materials and process errors, and to ensure that the batteries leaving the factory meet industry standards and customer needs.
[0003] Existing charge-discharge testers are research on detection technologies used to quickly identify the health status of lithium-ion batteries. They are specialized devices designed for the precise control and measurement of the charge-discharge process of lithium-ion batteries (and other secondary batteries), and for collecting key electrical performance parameters such as voltage, current, capacity, power, and temperature. Their core function is to simulate the charge-discharge conditions of batteries under different usage scenarios, and to evaluate core indicators such as battery capacity, cycle life, rate performance, and charge-discharge efficiency through quantitative data. They are a core measurement tool for battery research and development, production testing, and quality verification. Existing conveyor belts typically allow for adjustment of height and speed.
[0004] However, existing methods generally rely on manual use of charge and discharge testers to test lithium-ion batteries. When holding the test leads, it is necessary to manually touch the test points on the lithium-ion battery with the test leads, which has low testing efficiency and is not suitable for the rhythm of production lines. Furthermore, holding the test leads can easily cause the positive and negative electrodes to accidentally short-circuit due to hand tremors. If testing high-voltage, high-capacity cells, the instantaneous current of the short circuit is large, which may generate an electric arc and even pose a fire hazard.
[0005] Therefore, it is necessary to provide a new lithium-ion battery production testing structure to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of a preferred embodiment of a lithium-ion battery production testing structure provided by this utility model; Figure 2 A front structural diagram of this utility model; Figure 3 A side view of the present invention is provided.

[0019] In the specific implementation process, such as Figures 1-6 As shown, a lithium-ion battery production testing structure includes a testing box 1 and four load-bearing columns 101 located at the bottom of the testing box 1. A guide groove 102 is provided on one side surface of the testing box 1. An installation plate 2 is fixedly connected to the bottom of the inside of the testing box 1. The upper edge of the installation plate 2 is provided with opposing sliding grooves 202 and 203. Sliding components are provided in the sliding grooves 202 and 203. Furthermore, the sliding assembly includes a guide block 311, a rotating column 310, an octagonal bolt 308, a guide column 312, a connecting block 313, a connecting seat 314, and multiple probes 315. The guide block 311 is slidably connected in the first sliding groove 202 and the second sliding groove 203. One end of the rotating column 310 is rotatably connected to one end of the guide block 311. The end of the guide column 312 away from the guide block 311 is provided with a threaded hole 309, and the octagonal bolt 308 is threadedly connected to the threaded hole 309. The end of the guide block 311 away from the rotating column 310 is fixedly connected to one end of the guide column 312. The end of the guide column 312 away from the guide block 311 is fixedly connected to one end of the connecting block 313. The end of the connecting block 313 away from the guide column 312 is fixedly connected to one end of the connecting seat 314. The end of the connecting seat 314 away from the connecting block 313 is fixedly connected to one end of the multiple probes 315. The mounting plate 2 is also provided with a drive mechanism for driving the sliding assembly to reciprocate up and down.
[0020] Furthermore, the guide groove 102 is matched with the size of the connecting block 313 so that the connecting block 313 can slide within the guide groove 102. The size of sliding groove 1 202 and sliding groove 203 are equal, and their heights are equal, so that sliding groove 1 202 and sliding groove 203 can be used together to allow the guide block 311 to slide within them. Limiting blocks 4 are provided inside sliding groove 1 202 and sliding groove 203. The outer periphery of the limiting blocks 4 is fixedly connected to the inner side of sliding groove 1 202 and sliding groove 203. The limiting blocks 4 are located at the center of both ends of sliding groove 1 202 and sliding groove 203 so that they can be used for limiting and preventing the guide block 311 from falling into the bottom of sliding groove 1 202 and sliding groove 203 when the guide block 311 moves.
[0021] It should be noted that the test leads of the charge-discharge tester can be electrically connected to multiple probes 315. The four load-bearing columns 101 at the bottom of the test box 1 are used to support the test box 1. The guide groove 102 serves as the output position of the motor 3 drive end inside the test box 1. It can be connected to the rotating column 310 by the thread of the octagonal bolt 308 and the clamping connecting plate 306 to match the different positions of the octagonal bolt 308 in the limiting groove 307 to adjust the different running trajectories of multiple probes 315. The closer the octagonal bolt 308 is to the rotating column 305 in the limiting groove 307, the smaller the running trajectory of multiple probes 315. By adjusting the height and speed of the conveyor belt, it can be used to adapt to different testing speeds.
[0022] In some embodiments, reference is made to Figures 2-4 As shown, the drive mechanism includes a motor 3, a first pulley 301, a second pulley 302, a belt 303, a connecting vertical plate 201, a connecting plate 306, a first rotating column 304, and a second rotating column 305. The motor 3 is fixedly connected to the upper center of the mounting plate 2, and the output end of the motor 3 is fixedly connected to the center of one end of the first pulley 301. The upper edge of the mounting plate 2 is fixedly connected to one end of the connecting vertical plate 201, and one side of the upper end of the connecting vertical plate 201 is fixedly connected to one end of the first rotating column 304. The first rotating column 304 is located away from the connecting vertical plate. One end of 201 is rotatably connected to the center of one end of pulley 301. Pulley 301 and pulley 302 are connected by belt 303. The edge of pulley 302 away from rotating column 304 is rotatably connected to one end of rotating column 305. The end of rotating column 305 away from pulley 302 is rotatably connected to one end of connecting plate 306. A limiting groove 307 is provided at the end of connecting plate 306 away from rotating column 305. An octagonal bolt 308 passes through the limiting groove 307 and is threadedly connected to the threaded hole 309.
[0023] Furthermore, the height of the limiting block 4 is less than the height of the limiting groove 307, so as to prevent the limiting block 4 from limiting the guide block 311 when the reciprocating motion is not completed.
[0024] It should be noted that when motor 3 is started, the output end of motor 3 drives pulley 301 to rotate. Pulley 301 drives pulley 302 to rotate via belt 303. Pulley 302 drives connecting plate 306 to reciprocate. Connecting plate 306 drives guide block 311 to reciprocate via rotating column 310. Guide block 311 drives connecting block 313 to reciprocate within sliding groove 202 and sliding groove 203 via guide column 312. Connecting block 313 drives connecting seat 314 and multiple probes 315 at the bottom of connecting seat 314 to reciprocate, thereby detecting the detection points on the lithium-ion battery.
