Description

Technical Field

[0001] This invention belongs to the field of lithium battery packaging and testing technology, and in particular relates to an unmanned full inspection equipment and testing method for lithium battery packaging production lines. Background Technology

[0002] The lithium-ion battery packaging process mainly includes three stages: cell manufacturing, cell packaging, and battery pack packaging. Cell manufacturing is the first step in the lithium-ion battery packaging process, and it mainly includes the preparation of positive and negative electrode materials, electrode sheet preparation, and electrolyte formulation. Cell packaging assembles the cells into complete battery units, and it mainly includes cell assembly, cell packaging, and cell testing. Battery pack packaging assembles multiple cells into a battery pack, and it mainly includes the series and parallel connection of cells, battery pack packaging, and battery pack testing.

[0003] After the lithium battery pack is packaged, a series of inspections are carried out. One of these inspections is to use vision equipment to determine the packaging status of all battery packs on the lithium battery production line. In the current technology, most full inspection equipment using vision technology uses a turntable or conveyor belt to record and analyze the images after the battery pack reaches a designated position. However, the turntable or conveyor belt lacks a limiting component to block the battery pack when it stops. Different stopping positions will have deviations, resulting in inconsistent product positions captured by the vision equipment, which brings inconvenience to vision analysis and affects the accuracy of data analysis and judgment.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0050] This invention provides an unmanned full-inspection device for a lithium battery packaging production line, such as... Figures 1-7 As shown, the unmanned full inspection equipment for a lithium battery packaging production line includes:

[0051] A platform 110 is provided with a feeding mechanism 130 and a discharging mechanism 120.

[0052] Test platform 300, which is mounted on stand 110;

[0053] The feeding conveyor belt 210 and the discharging conveyor belt 220 are provided. The platform 110 is located at the intersection of the feeding conveyor belt 210 and the discharging conveyor belt 220. The feeding mechanism 130 pushes the lithium battery packs conveyed on the feeding conveyor belt 210 to the testing platform 300. The discharging mechanism 120 pushes the lithium battery packs that have completed testing on the testing platform 300 to the discharging conveyor belt 220.

[0054] A visual monitoring module, comprising a first visual monitoring module 410 and a second visual monitoring module 420;

[0055] The test platform 300 includes a turntable assembly 310 and a positioning assembly 320. The lithium battery pack passes through a first phase and a second phase, which are composed of a first vision monitoring module 410 and a second vision monitoring module 420, under the drive of the positioning assembly 320. The vision monitoring modules acquire the packaging status of the lithium battery pack in the first phase and the second phase respectively. The first vision monitoring module 410 is provided with a limit module 414, which performs precise limiting when the positioning assembly 320 passes through the first phase and the second phase.

[0056] In this embodiment, the feeding conveyor belt 210 and the discharging conveyor belt 220 are located within the lithium battery packaging production line. With the assistance of the feeding mechanism 130 and the discharging mechanism 120, the lithium battery pack slides from the feeding conveyor belt 210 to the positioning component 320 on the testing platform 300, or from the positioning component 320 on the testing platform 300 to the discharging conveyor belt 220. After entering the testing platform 300, the lithium battery pack is inspected by a visual monitoring module to check its packaging status. The feeding mechanism 130 and the discharging mechanism 120 employ existing technology-level pushing mechanisms to complete the transfer of the lithium battery pack between the feeding conveyor belt 210 and the testing platform 300, and between the testing platform 300 and the discharging mechanism 120, when the feeding conveyor belt 210 and the discharging conveyor belt 220 are stationary. The feeding conveyor belt 210 and the discharging conveyor belt 220 also employ existing technology-based conveyor belt mechanisms with fixing functions to ensure that the lithium battery pack is in an upright position.

[0057] In this embodiment, the positioning component 320, as a lithium battery pack support structure, rotates along with the turntable component 310. The limiting module 414 blocks the positioning component 320 during the rotation of the turntable component 310 and samples and captures image data at the blocking point. The limiting module 414 includes a first limiting rod 4141 and a second limiting rod 4142. The position where the first limiting rod 4141 blocks the positioning component 320 is the first phase, and similarly, the position where the second limiting rod 4142 blocks the positioning component 320 is the second phase. The first and second phases are generated by the blocking effect of the limiting module 414. The first and second limiting rods 4141, in conjunction with the positioning component 320, block the lithium battery pack that slides into the positioning component 320 at a fixed position. This active blocking achieves precise positioning, reduces the deviation of the shooting angle of the visual monitoring module, obtains shooting data at a fixed angle, and improves the accuracy of the comparison data.

[0058] In this embodiment, the first visual monitoring module 410 is disposed above the test platform 300. The first visual monitoring module 410 includes a front visual unit 412 and a rear visual unit 413. The second visual monitoring module 420 includes a first visual unit 422 and a second visual unit 423. The front visual unit 412 and the first visual unit 422 correspond to a first phase, and the rear visual unit 413 and the second visual unit 423 correspond to a second phase. The front visual unit 412 is aligned with the side of the lithium battery pack entering the first phase, the first visual unit 422 is aligned with the side of the lithium battery pack entering the first phase away from the front visual unit 412, the rear visual unit 413 is aligned with the side of the lithium battery pack entering the second phase, and the second visual unit 423 is aligned with the side of the lithium battery pack entering the second phase away from the rear visual unit 413.

[0059] The first visual unit 422, the second visual unit 423, the front visual unit 412, and the rear visual unit 413 employ existing visual monitoring and comparison technology. The lithium battery pack sequentially enters the first phase and the second phase. The front visual unit 412 and the rear visual unit 413 observe the same side of the lithium battery pack in the first phase and the second phase, respectively. The first visual unit 422 and the second visual unit 423 observe the same side in the first phase and the second phase, respectively. The data captured by the front visual unit 412 and the rear visual unit 413 are compared and verified a second time to improve the accuracy of the visual judgment of the packaging result. The first visual unit 422 and the second visual unit 423 perform a second comparison and identification on the other side of the lithium battery pack to improve the accuracy of the identification result.

[0061] Top sealing plate 311 and bottom plate 312;

[0062] Sliding groove 314, the sliding groove 314 is provided on the upper sealing plate 311;

[0063] Limiting plates 313, the number of limiting plates 313 inside the bottom plate 312 is equal to the number of sliding grooves 314;

[0064] The positioning component 320 has a sliding groove 314 that penetrates the upper sealing plate 311, and the end of the positioning component 320 is in contact with the limiting plate 313.

[0065] In this embodiment, the positioning component 320 is hinged to the central shaft 315 provided on the base plate 312. The positioning component 320 is pressed against the edge of the sliding groove 314 by the limiting plate 313. When the stepper motor provided at the bottom of the base plate 312 rotates, the positioning component 320 will rotate along with the turntable component 310. The lithium battery pack transferred from the feeding conveyor belt 210 to the positioning component 320 will rotate synchronously.

[0066] When the positioning component 320 touches the first limiting rod 4141 or the second limiting rod 4142, the positioning component 320 will deflect around the central axis 315 under the action of resistance, and the limiting plate 313 will provide reverse support for the positioning component 320, ensuring that the positioning component 320 maintains contact with the first limiting rod 4141 or the second limiting rod 4142; when the positioning component 320 reaches the first limiting rod 4141 or the second limiting rod 4142, it will be stopped by the first limiting rod 4141 or the second limiting rod 4142. 142 timely interception, using the cooperation of the limiting plate 313 and the central shaft 315 to make the positioning component 320 fit against the first limiting rod 4141 or the second limiting rod 4142, so that the first limiting rod 4141 or the second limiting rod 4142 can achieve precise limiting of the positioning component 320, improve the limiting accuracy, and avoid the problem of insufficient deflection angle caused by using rotating motor equipment. Through precise limiting, the visual monitoring module can obtain more accurate image data, avoiding the situation where the test results are not accurate due to deviation.

The first positioning unit 321, the second positioning unit 322, the third positioning unit 323, the fourth positioning unit 324, the fifth positioning unit 325, and the sixth positioning unit 326 are nested and hinged to the central axis 315.

[0068] In this embodiment, the first positioning unit 321, the second positioning unit 322, the third positioning unit 323, the fourth positioning unit 324, the fifth positioning unit 325, and the sixth positioning unit 326 are all independent loading modules. Each independent loading module is loaded with a lithium battery pack by the feeding mechanism 130. The first positioning unit 321, the second positioning unit 322, the third positioning unit 323, the fourth positioning unit 324, the fifth positioning unit 325, and the sixth positioning unit 326 sequentially undergo the loading, reaching the first phase recording data, reaching the second phase recording data, and unloading stages under the drive of the turntable assembly 310. The number of loading modules of the positioning assembly 320 can be matched according to production needs, with a minimum of four sets to ensure continuous operation of the four stages.

[0069] In this embodiment, the orientation of the feeding conveyor belt 210 and the discharging conveyor belt 220 is adjusted by angle in conjunction with the positioning component 320. Generally, the orientation of the feeding conveyor belt 210 and the discharging conveyor belt 220 is adapted to the orientation of the positioning component 320 to facilitate the loading and unloading of lithium battery packs by the discharging mechanism 120 and the feeding mechanism 130. The discharging mechanism 120 and the feeding mechanism 130 mainly adopt the existing robotic arm structure. The feeding mechanism 130 can grab lithium battery packs from the feeding conveyor belt 210 and accurately place them on the positioning component 320. The discharging mechanism 120 can grab lithium battery packs from the positioning component 320 and place them on the discharging conveyor belt 220. When the unmanned full inspection equipment of the lithium battery packaging production line finds unqualified products, the discharging mechanism 120 directly places the lithium battery packs on the defective product conveyor belt. The defective product conveyor belt is arranged perpendicular to the discharging conveyor belt 220 and will transport the products to other areas.

The limiting plate 313 is equipped with multiple springs, which are connected to the baffle 3213 via the springs. Under normal circumstances, the limiting plate 313 uses its elastic force to press the slide rail 3212 against the edge of the sliding groove 314. When the slide rail 3212 collides with the first limiting rod 4141 or the second limiting rod 4142, the slide rail 3212 will rotate under the influence of the connecting rod 3211. When the central axis 315 deflects, the limiting plate 313 uses elastic force to attach the slide rail 3212 to the first limiting rod 4141 or the second limiting rod 4142, thereby keeping the lithium battery pack mounted on the slide rail 3212 at a fixed angle with the first limiting rod 4141 or the second limiting rod 4142. The precise position is limited by the cooperation between the limiting plate 313, the slide rail 3212 and the first limiting rod 4141 or the second limiting rod 4142, thereby keeping the lithium battery pack at a fixed shooting angle of the visual monitoring module, effectively improving the accuracy of the visual monitoring module's shooting.

[0077] In this embodiment, the limiting module 414 adopts screw drive technology, which can achieve precise control of the first limiting rod 4141 and the second limiting rod 4142. The limiting module 414 operates the extension and retraction of the first limiting rod 4141 and the second limiting rod 4142 to achieve the purpose of limiting the test platform 300; while the front vision unit 412 and the rear vision unit 413 adopt existing technology.
