Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and more specifically, to a recycling and screening device for waste lithium batteries of new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources and integrate advanced technologies in vehicle power control and driving. They have advanced technical principles, new technologies, and new structures. Among them, new energy vehicles using lithium batteries as power sources are relatively common. However, lithium batteries themselves will have an impact on the environment. When dealing with waste new energy vehicles, it is necessary to recycle the lithium batteries and screen out the lithium batteries that can still be used.

[0003] After retrieval, the utility model patent with the publication number of CN218982399U discloses a recycling and screening device for waste vehicle lithium batteries, including a screening bottom plate. An upper cover is arranged on the upper side of the screening bottom plate. An automatic lifting mechanism is arranged between the screening bottom plate and the upper cover. Equally spaced bottom cylinders are opened on the top wall surface of the screening bottom plate. Equally spaced top cylinders are opened on the bottom wall surface of the upper cover. The bottom cylinders and the top cylinders are in corresponding up and down positions. A vertical plate is fixedly installed on the rear side wall surface of the upper cover, and equally spaced displays are also installed on the vertical plate. For this recycling and screening device for waste vehicle lithium batteries, this solution realizes the rapid recycling and screening of multiple groups of lithium batteries. The battery capacity detector detects each lithium battery, and the detection data of the battery capacity detector is transmitted to the display for display through an electrical signal, so as to quickly separate and screen out qualified lithium batteries. Each detected lithium battery is equipped with its own display, so it can assist in improving the recycling and screening efficiency of the lithium batteries in the present invention.

[0004] However, the above patent still has the following deficiencies: Although multiple lithium batteries can be detected and screened at one time, a certain amount of time will still be wasted during the processes of feeding, detecting, and discharging the lithium batteries, thus affecting the screening efficiency; and it is not convenient to sort and store the waste lithium batteries after screening. For this reason, we propose a recycling and screening device for waste lithium batteries of new energy vehicles. Summary of the Utility Model
