Description

Technical Field

[0002] With the increasing popularity of new energy vehicles, the volume of scrapped lithium batteries, which serve as their power sources, is increasing. Lithium batteries contain valuable metals such as cobalt, nickel, and lithium. Recycling these metals not only alleviates pressure on raw material supply and reduces battery production costs, but also reduces reliance on primary mineral resources. Furthermore, if used batteries are not professionally treated, the heavy metals and hazardous substances they contain can leach into the soil, contaminate water sources, and cause long-term and irreversible damage to ecosystems. Advanced recycling processes can render hazardous substances harmless, minimizing environmental pollution. The valuable metal content in recycled lithium batteries is far higher than that extracted from ores, making them of significant economic value.

[0014] A lithium battery recycling method comprises the following steps: S1: A plurality of discharge chambers are provided on the inner side of the discharge battery, and the inner side of the discharge chamber is filled with discharge liquid. Two stacking units are respectively provided at the two ends of the four first guide rails. The power is turned on, and the lithium batteries to be recycled are conveyed to the inner side of the protective shell by the conveyor. The second transmission motor is started, so that the second transmission motor drives the first connecting slide to slide along the second guide rail through the second guide wheel. At the same time, the third transmission motor drives the second connecting slide to slide horizontally through the first transmission screw under the support of the transverse mounting slide, thereby realizing the position adjustment of the connecting lifting mechanism, and then driving the connecting lifting mechanism to move to the top of one of the stacking units through the first connecting slide and the transverse mounting slide; S2: A plurality of battery positioning and clamping mechanisms are stacked on the upper end surface of the movable conversion seat and between the four limiting angle plates, wherein the bottom end of the positioning strip passes through the positioning waist-shaped hole and is fixedly connected to the movable conversion seat, and then the plurality of battery positioning and clamping mechanisms are positioned and stacked through the limiting angle plates and the positioning strips, and the fourth transmission motor is started, so that the fourth transmission motor drives the two winding racks to rotate in opposite directions under the support of the second connecting slide, and then the winding rack adjusts the lowering of the lifting connecting plate through the steel cable, and when the lifting connecting plate is in contact with the upper end surface of the central connecting frame, the bottom end of the synchronous dial seat passes through the lifting connecting plate and fits on the outer side of the middle of the transmission slide; S3: The electric push rod drives the clamping blocks to be inserted into the positioning grooves provided at both ends of the central connecting frame under the support of the lifting connecting plate, and then the electric push rod and the clamping blocks facilitate the fixed connection between the lifting connecting plate and the central connecting frame, and then the battery positioning clamping mechanism is lifted and separated from the stacking unit, so that the two-way adjustment mechanism and the connection lifting mechanism drive the battery positioning clamping mechanism to be placed on the upper end surface of the battery.

The present invention realizes the position adjustment of the connection and lifting mechanism through a two-way adjustment mechanism, and multiple battery positioning and clamping mechanisms are positioned and stacked by limiting angle plates and positioning strips. The two reeling frames rotate in opposite directions, and then the reeling frames adjust the lifting connecting plate downward through the steel cables and make contact with the upper end surface of the center connecting frame. The electric push rod drives the clamping block to be inserted into the positioning grooves provided at both ends of the center connecting frame, so as to lift the battery positioning and clamping mechanism and separate it from the stacking unit. It is convenient for the two-way adjustment mechanism and the connection and lifting mechanism to drive the battery positioning and clamping mechanism to be placed on the upper end surface of the battery. The synchronous dial seat drives the clamping angle plates to slide toward each other on the lower end surface of the clamping connecting plate through the transmission slide, and then the battery can be clamped by the clamping angle plates, so as to maintain a stable connection between the clamping connecting plate and the battery. 2. The present invention uses a two-way adjustment mechanism and a connection and lifting mechanism to lift the battery through a battery positioning and clamping mechanism and place it on the inner side of the battery storage box, and separates the clamping block from the central connecting frame, so that the lifting connection plate is disengaged from the battery positioning and clamping mechanism, effectively preventing the components in the connection and lifting mechanism from being affected by the discharge fluid and causing a shortening of the service life. The battery storage box can synchronously discharge multiple batteries through the discharge fluid in multiple discharge chambers, and the first transmission motor drives the first guide wheel to roll on the upper end surface of the first guide rail to adjust the position of the stacking unit, and then the position of the two stacking units is converted, which can facilitate the corresponding clamping and suspension operations through the battery positioning and clamping mechanism when the battery is continuously input.
