Description

Technical Field

[0001] This utility model relates to the field of battery recycling equipment technology, specifically to a testing device for the cascade utilization of waste batteries. Background Technology

[0002] With the widespread application of new energy vehicles, the recycling and reuse of used power batteries has received increasing attention. Currently, there are two main methods for recycling used electric vehicle batteries: cascade utilization and regeneration. Cascade utilization refers to continuously "downgrading" the battery until its last bit of value is extracted. Before cascade utilization, the used batteries need to be tested for proper sorting and reuse.

[0003] In existing technologies, such as the "Battery Testing Equipment" in Chinese Patent No. CN113655394B, conductive sheets on a T-shaped slide rail are connected to the positive and negative electrode sliding connection components. This allows for automatic X-ray non-destructive testing and lithium battery pack testing during battery transport, replacing traditional manual individual feeding and testing, significantly improving battery testing quality and efficiency. However, existing technologies still have the following problems: Insufficient testing accuracy: Existing equipment typically only performs single-indicator testing, failing to comprehensively evaluate battery performance, resulting in inaccurate test results that cannot meet the needs of actual cascade utilization. For example, conductivity testing alone cannot accurately determine the battery's capacity and internal resistance state, which are crucial for battery cascade utilization. High risk of manual operation: Manual testing of used batteries is prone to danger due to varying storage conditions, potentially causing injury to testing personnel. While existing equipment achieves partial automation, manual intervention is still required during battery loading, unloading, and testing, posing safety hazards. Utility Model Content

[0017] 1. This waste battery recycling testing equipment, through the coordinated arrangement of a support cabinet, a first conveying component, a testing component, a sorting component, and multiple second conveying components, achieves comprehensive testing and precise classification. This invention, by incorporating a conductivity tester, a DC internal resistance tester, and a capacity tester, can comprehensively test multiple key performance indicators of waste batteries.

[0029] Please see Figures 1 to 6This utility model provides a technical solution: a waste battery cascade utilization testing device, including a support cabinet 1, a first conveying component 2, a testing component, a sorting component 6, and multiple second conveying components 5. A control board is installed inside the support cabinet 1, and the control board is connected to the first conveying component 2, the testing component, the sorting component 6, and each of the second conveying components 5. The first conveying component 2 is fixedly installed above the support cabinet 1, and conveys multiple waste batteries 3. The testing component includes a conductivity tester, a DC internal resistance tester, a capacity tester, and three drive components 4. The conductivity tester, DC internal resistance tester, and capacity tester are all installed inside the support cabinet 1. The three drive components 4 are fixedly installed on the first conveying component 2, and the detection contact wires of the conductivity tester, DC internal resistance tester, and capacity tester are respectively fixedly installed on the output shaft ends of the three drive components 4. The drive components 4 drive the detection contact wires of the conductivity tester, DC internal resistance tester, or capacity tester to contact the conductive terminals of the waste batteries 3. The sorting component 6 is located at one end of the support cabinet 1, and the various second conveying components 5 are distributed around the sorting component 6. The sorting component 6 sorts the waste batteries 3 after they have been detected by the detection component, and then conveys the waste batteries 3 out through a second conveying component 5.

[0030] The support cabinet 1 supports the first conveying component 2 and holds electrical equipment such as a conductivity tester, a DC internal resistance tester, a capacity tester, and a control board. The first conveying component 2 conveys the used batteries 3, moving them towards the sorting component 6. The control board includes, but is not limited to, an industrial computer, a programmable logic controller (PLC), or a processor. The control board contains logic control programs, timing control programs, and other software programs to meet the automation control requirements of the entire equipment.

[0031] The conductivity tester is used to detect the internal resistance of the used battery 3. By injecting an AC signal of about 1kHz, it measures the internal impedance of the battery, reflecting the aging state such as plate sulfation and electrolyte drying. This includes, but is not limited to, the CN61M-GT-DD01 conductivity tester. The DC internal resistance tester is used to detect the DC internal resistance of the used battery 3. By discharging under a constant load of 10-100A, it measures the instantaneous voltage drop (ΔV / ΔI), directly reflecting the ohmic internal resistance (plate / connection resistance). This includes, but is not limited to, the HDBS-II DC internal resistance tester. The capacity tester is used to detect the actual capacity of the used battery 3. It performs constant current charging and discharging to the cutoff voltage and calculates the discharge capacity (e.g., for lithium batteries discharged at 0.5C, capacity <80% is discarded). This includes, but is not limited to, the Dingchen DCL8006A capacity tester. The detection components are used to detect the battery internal resistance, DC internal resistance, and capacity of the used battery 3 during transportation. The three drive components are designated as the first drive component 4, the second drive component 4, and the third drive component 4. The first drive component 4 drives the detection contact wire of the conductivity tester to contact the conductive terminal of the waste battery 3. The second drive component 4 drives the detection contact wire of the DC internal resistance tester to contact the conductive terminal of the waste battery 3. The third drive component 4 drives the detection contact wire of the capacity tester to contact the conductive terminal of the waste battery 3. After the detection components complete the detection of the waste battery 3, the conductivity tester, DC internal resistance tester, and capacity tester in the detection components transmit the relevant data to the control board. The control board classifies the waste battery 3 according to the relevant data. The sorting component 6 then picks out the sorted waste batteries 3, which are then transported out by different second conveying components 5.

[0032] Specifically, the first conveying component 2 includes a first servo motor 202, a first conveyor belt 203, two square tubes 201, and two first rotating rollers. The two square tubes 201 are fixedly installed on the support cabinet 1. The two ends of the first rotating rollers are rotatably connected to the two square tubes 201 respectively, and the two first rotating rollers are parallel. The first conveyor belt 203 is arranged around the two first rotating rollers. The first servo motor 202 is fixedly installed on one of the square tubes 201, and the first servo motor 202 is connected to the two first rotating rollers respectively.

[0033] The primary function of the first conveying component 2 is to transport the used batteries 3 from the inlet to the detection position. A first servo motor 202 drives two first rotating rollers to rotate via a transmission connection, thereby moving the first conveyor belt 203. The used batteries 3 are placed on the first conveyor belt 203 and are transported to the area below the detection component as the conveyor belt moves. During the conveying process, the speed and stability of the first conveyor belt 203 are controlled by the first servo motor 202 to ensure that the batteries accurately reach the detection position. The control board is electrically connected to the first servo motor 202 and controls its start and stop operations.

[0034] More specifically, all three drive components 4 are fixedly mounted on two square tubes 201, and the three drive components 4 are arranged laterally. Each drive component 4 includes a support frame 401, a first servo electric cylinder 402, and a second servo electric cylinder 404. The first servo electric cylinder 402 and the second servo electric cylinder 404 are both fixedly mounted on the support frame 401, and their output shaft ends both penetrate the support frame 401. A first connecting plate 403 is fixedly mounted on the output shaft end of the first servo electric cylinder 402, and a second connecting plate 405 is fixedly mounted on the output shaft end of the second servo electric cylinder 404. The detection contact wires of the conductivity tester, DC internal resistance tester, or capacitance tester are electrically connected to the first connecting plate 403 and the second connecting plate 405, respectively.

[0035] The system comprises three driving components: a first driving component 4, a second driving component 4, and a third driving component 4. The first driving component 4 drives the detection contact wire of the conductivity tester to contact the conductive terminal of the used battery 3; the second driving component 4 drives the detection contact wire of the DC internal resistance tester to contact the conductive terminal of the used battery 3; and the third driving component 4 drives the detection contact wire of the capacity tester to contact the conductive terminal of the used battery 3. The output shaft of the first servo electric cylinder 402 drives the first connecting plate 403 to move vertically. The first connecting plate 403 causes the detection contact wire A of the conductivity tester, DC internal resistance tester, or capacity tester to contact the conductive terminal A of the used battery 3. The contact portion between the first connecting plate 403 and the output shaft of the first servo electric cylinder 402 is insulated, and the first connecting plate 403 is conductive. The output shaft of the second servo electric cylinder 404 drives the second connecting plate 405 to move up and down. The second connecting plate 405 causes the detection contact wire B of the conductivity tester, DC internal resistance tester, or capacity tester to contact the conductive terminal B of the waste battery 3. The contact portion between the second connecting plate 405 and the output shaft of the second servo electric cylinder 404 is insulated, and the second connecting plate 405 is conductive. The control board is electrically connected to the first servo electric cylinder 402 and the second servo electric cylinder 404 in the three drive components 4, and controls the start and stop of the first servo electric cylinder 402 and the second servo electric cylinder 404 in the three drive components 4.

[0036] Specifically, the sorting component 6 includes a rotary table 601, a support column 602, a base 603, a feeding assembly 604, and a third servo motor 605. The lower end of the support column 602 is fixedly connected to the base 603, and the upper end of the support column 602 is rotatably connected to the rotary table 601. The feeding assembly 604 is mounted on the rotary table 601, and the third servo motor 605 is fixedly mounted on the support column 602. The third servo motor 605 is connected to the rotary table 601 in a transmission manner, and drives the rotary table 601 to rotate.

[0037] In this process, the used batteries 3 conveyed by the first conveying component 2 are moved onto the feeding assembly 604. After the third servo motor 605 starts, it drives the rotary table 601 to rotate, which in turn drives the feeding assembly 604 to rotate, and the feeding assembly 604 drives the used batteries 3 to rotate. The rotation of the rotary table 601 aligns the feeding assembly 604 with the corresponding second conveying component 5. The feeding assembly 604 then conveys the used batteries 3 onto the corresponding second conveying component 5, thus achieving the sorting of the used batteries 3. The control board is electrically connected to the third servo motor 605 and controls its start and stop.

[0038] More specifically, the feeding assembly 604 includes a second conveyor belt 6041, a second servo motor 6042, and two second rotating rollers. The two second rotating rollers are rotatably mounted on the rotary table 601. The second conveyor belt 6041 is arranged around the outer side wall of the two second rotating rollers. The second servo motor 6042 is fixedly mounted on the rotary table 601 and is connected to the two second rotating rollers respectively.

[0039] The control board is electrically connected to the second servo motor 6042, and controls the start and stop of the second servo motor 6042. After the second servo motor 6042 is started, it drives the second rotating roller to rotate, which in turn drives the second conveyor belt 6041 to rotate, and the second conveyor belt 6041 transports the waste battery 3.

[0040] More specifically, a gear 606 is fixedly installed on the output shaft end of the third servo motor 605, and an external gear ring 607 is fitted on the upper outer side wall of the support column 602 and the two are rotatably connected. The external gear ring 607 is fixedly connected to the rotary table 601, and the gear 606 meshes with the external gear ring 607.

[0041] When the third servo motor 605 is started, the output shaft of the third servo motor 605 drives the gear 606 to rotate, the gear 606 pushes the external gear ring 607 to rotate, and the external gear ring 607 drives the rotary table 601 to rotate.

[0042] Specifically, multiple support legs 7 are fixedly installed below the second conveying component 5.

[0043] The support leg 7 supports the second conveying component 5. The structural features, working principle, and related components of the second conveying component 5 in this technical solution are consistent with those of the first conveying component 2; therefore, the second conveying component 5 will not be described in detail. The control board is electrically connected to the servo motors in each of the second conveying components 5, and the control board can start and stop the operation of each second conveying component 5.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
