Description

Technical Field

[0002] Lithium-ion battery tiered utilization refers to the recycling process of dismantling, testing, screening, and reassembling used power lithium-ion battery packs or cells into healthy battery packs or battery systems for reuse. This method is mainly applicable to retired power batteries with a capacity between 20% and 80%, and is typically used in scenarios with lower requirements for battery performance, such as grid peak shaving and frequency regulation, wind and solar energy storage, and low-speed electric vehicles.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0030] Example 1:

[0031] like Figure 1-8As shown, the battery testing equipment provided by this utility model includes: a conveyor track 1, which is similar to the dual-track design used in SMT (the PCB board is supported by two conveyor belts on both sides for transport). The conveyor track 1 can be set as a straight line or a ring. This embodiment uses a straight line as an example for explanation, and its detailed structure will not be described here. A multi-station support mechanism 2 and a multi-station testing mechanism 3 are installed on the conveyor track 1. The two ends of the multi-station support mechanism 2 are supported on the conveyor track 1 for transport. The multi-station testing mechanism 3 can simultaneously test the power of multiple batteries. Specifically, the multi-station support mechanism 2 includes a support plate 21. The two sides of the support plate 21 are supported on the conveying track 1. The spacing of the conveying track 1 is adapted to the support plate 21 to ensure the positional accuracy of the support plate 21. The support plate 21 is conveyed by the conveying track 1 to the bottom of the multi-station detection mechanism 3. A position sensor or other type of position detection device should be installed on the conveying track 1 so that the support plate 21 stops when it is exactly under the multi-station detection mechanism 3. This will not be elaborated further here. Two clamping plates 23 are installed on the support plate 21, one of which is fixed and the other is movable. An adjustment component 22 is installed between the two clamping plates 23. The adjustment component 22 is used to adjust the spacing between the two clamping plates 23 so that multiple battery bodies 6 are evenly clamped and fixed on the top of the support plate 21. It is worth noting that a slot adapted to the width of the battery (not shown in the figure) should be opened on the inner side of the clamping plate 23 to position and clamp the battery. Through the multi-station support mechanism 2 designed above, multiple battery bodies 6 can be supported and fixed at the same time. The multi-station testing mechanism 3 includes a support frame 31, which is fixed to the support of the conveyor rail 1. A horizontal plate 32 is fixedly installed on the support frame 31, and a testing plate 34 is installed below the horizontal plate 32. The testing plate 34 is connected to a lifting cylinder 33 fixedly installed on the horizontal plate 32. Multiple testing electrode groups are installed at the bottom of the testing plate 34, and each testing electrode group includes two testing electrodes 36. The testing electrodes 36 are connected to a power detection device placed on one side of the equipment. The spacing between the testing electrode groups is the same as the spacing between the battery bodies 6 placed on the support frame 31.In use, fully charged battery bodies 6 are pre-sorted and fixed onto the multi-station support mechanism 2 according to their specifications. Each support frame 31 should have a motor body 6 of the same specification. The multi-station support mechanism 2 is placed on the conveyor rail 1, which transports it to below the multi-station detection mechanism 3. At this point, the detection electrode 36 is directly above the positive / negative terminal of the battery body 6. Then, the lifting cylinder 33 is activated, causing the horizontal plate 32 to descend, bringing the detection electrode 36 into contact with the positive and negative terminals of the battery body 6. The power detection device detects the power level of the battery body 6. After detection, the detection electrode 6 rises and resets. The conveyor rail 1 then transports the detected battery body 6 to the next stage. A label printer on one side of the equipment prints a label on the top or side of the battery body 6. The printed content is related to the actual power level (capacity), facilitating subsequent sorting of the battery body 6. It is worth noting that the label printer and the power detection device share a server, enabling database sharing and real-time updates of the battery power label printing data.

[0032] By setting up a conveyor track 1, a multi-station support mechanism 2, and a multi-station detection mechanism 3, the multi-station support mechanism 2 can simultaneously support and fix multiple batteries, while the multi-station detection mechanism 3 can simultaneously detect the power of multiple batteries, which can effectively improve battery detection efficiency.

[0033] Example 2:

[0034] like Figure 7-8 As shown, in this embodiment, two adjusting components are symmetrically arranged at the bottom of the detection plate 34. These adjusting components are used to adjust the position of the detection electrode 36. Each adjusting component includes a slider 37 slidably mounted on the bottom of the detection plate 34. An electrode fixing plate 35 is fixedly mounted on the bottom of the slider 37, and the detection electrode 36 is fixed on the electrode fixing plate 35. A servo motor 39 is mounted on one side of the detection plate 34, and a lead screw 38 is fixedly mounted on the output shaft of the servo motor 39. The lead screw 38 is connected to the slider 37 via a lead screw and nut pair. In use, the distance between the positive and negative electrodes of different batteries varies. In this case, the servo motor 39 can be activated, causing the lead screw 38 to move the slider 37 laterally, thereby adjusting the position of the electrode fixing plate 35 so that the detection electrode 36 can align with the positive / negative electrodes of the battery body 6. It is worth noting that the two electrode fixing plates 35 correspond to the positive and negative electrodes of the battery body 6, respectively.

[0035] By symmetrically arranging two adjustment components at the bottom of the detection plate 34, the position of the detection electrode 36 can be easily adjusted to detect different types of batteries.

[0036] Example 3:

[0037] like Figure 3-4As shown, in this embodiment, the conveying track 1 runs continuously. An interception component 5 is installed inside the conveying track 1 to intercept the support plate 21. The interception component 5 includes an interception plate 51, with both sides of the interception plate 51 fixedly connected to the bracket of the conveying track 1. A sensor 52 (infrared or laser rangefinder) is installed on the interception plate 51, and an interception cylinder 53 is installed on the interception plate 51. The interception cylinder 53 is located behind the sensor 52 and connected to the control terminal of the sensor 52. The sensor 52 can also be linked with the server of the power detection equipment. An interceptor 54 is fixedly installed at the top of the interception cylinder 53. In use, when the multi-station support mechanism 2 is conveyed on the conveying track 1, when the support plate 21 moves above the sensor 52, the control terminal of the sensor 52 sends a signal to the controller of the interception cylinder 53, causing the interception cylinder 53 to start, causing the interceptor 54 to rise and block the support plate 21 from continuing to move forward. This achieves the interception of the multi-station support mechanism 2. After the detection is completed, the interceptor 54 is manually or automatically controlled by the program to descend, releasing the interception of the multi-station support mechanism 2. It is worth noting that the interception component 5 can be installed on any position on the conveyor track 1 where interception operations are required on the multi-station support mechanism 2, facilitating the inspection of the upper and lower tracks or batteries of the multi-station support mechanism 2.

[0038] By installing the interception component 5 inside the conveyor track 1, it is possible to conveniently intercept the multi-station support mechanism 2 at the location where it is necessary to stop it.

[0039] Example 4:

[0040] like Figure 1 As shown, a robotic arm 4 is installed on the side of the conveyor track 1. Multiple robotic arms 4 can be installed at the loading, unloading and battery sorting positions. An interception component 5 should also be installed at the unloading position. In use, the robotic arm 4 can be used to place the multi-station support mechanism 2 from the ground onto the conveyor track 1 and can easily remove it from the conveyor track 1 to the ground. The robotic arm 4 can also install labels to remove the battery body 6 from the support plate 1 for sorting and placement.

[0041] By installing a robotic arm 4 on the side of the conveyor track 1, the automation level of the equipment can be effectively improved and the labor intensity can be reduced.

[0042] Example 5:

[0043] In this embodiment, a camera is installed below the multi-station detection mechanism 3. The camera can be mounted on the support frame 31 with the lens facing downwards. With the help of appropriate equipment, it can measure the distance between the battery tabs (positive and negative terminals). After the distance measurement is completed, based on the reference position of the battery cell, the servo motor 39 on the multi-station detection mechanism 3 can move the detection electrode 36 left and right, thereby achieving automatic alignment between the detection electrode 36 and the battery tabs.

[0044] Furthermore, before inspecting the battery, the device takes pictures of the battery's appearance using an equipped camera and uses machine learning methods to check and determine whether there is any damage to the appearance.

[0045] Furthermore, based on the battery testing results, the equipment can print and affix parameter labels such as capacity, resistance, and classification suggestions using the onboard marking machine and testing equipment.

[0046] Furthermore, the robotic arm 4 can also screen, classify, and arrange battery cells based on the battery testing results.

[0047] Working principle: In use, the fully charged battery bodies 6 are pre-sorted and fixed on the multi-station support mechanism 2 according to their specifications. That is, the motor bodies 6 on each support frame 31 should be of the same specifications. The multi-station support mechanism 2 is placed on the conveyor rail 1. The conveyor rail 1 transports the multi-station support mechanism 2 to the bottom of the multi-station detection mechanism 3 and stops. At this time, the detection electrode 36 is located directly above the positive / negative terminal of the battery body 6. Then, the lifting cylinder 33 is activated to drive the horizontal plate 32 to descend, so that the detection electrode 36 contacts the positive and negative terminals of the battery body 6. The power detection device detects the power of the battery body 6. After the power detection, the detection electrode 6 rises and resets. Then, the conveyor rail 1 transports the tested battery body 6 to the rear section. The label printer on one side of the equipment prints a label on the top or side of the battery body 6. The printed content is related to its actual power (capacity) to facilitate the subsequent sorting of the battery body 6.
