Description

Technical Field

[0001] The present invention relates to the field of power battery recycling and processing, and in particular to a recycling device and method for automatically classifying and processing power batteries of different specifications. Background Art

[0002] Power batteries refer to batteries that provide power, mainly lead-acid batteries and lithium iron phosphate batteries. They are the most consumed type of batteries in the world. If the lead, lithium and other metal resources are not recycled, it will cause waste of important metal resources and environmental pollution, especially lead metal resources. Therefore, how to efficiently recycle waste power batteries without polluting the environment has become an urgent matter.

[0003] On the one hand, the current power battery recycling industry mainly uses the method of centralized crushing by crushers, that is, "mixed separation" to crush and separate power batteries. This method of crushing first and then separating not only causes secondary pollution to the environment, but also increases the difficulty and cost of later collection, and also requires a lot of manual labor to assist in the crushing and recycling work; on the other hand, the state of power battery recycling and processing is chaotic, there are many power battery models, and the irreversibility of power battery production technology determines that different types of batteries must be classified and processed, and the current processing equipment requires most of the classification and processing to be done manually, which is not environmentally friendly and endangers manual safety. At the same time, the separation and recycling rate of various battery components after the extensive treatment method of centralized crushing is also very low. Summary of the invention

[0004] The technical problem that the present invention aims to solve is: in view of the problems of multiple existing power battery models, irreversibility of power battery production processes, low degree of automation of disassembly processes, small scope of adaptation, and potential safety hazards, a disassembly process and device that are adaptable to power batteries of multiple specifications are provided. For batteries of different specifications, the same set of equipment and methods can be used for differentiated classification and automatic processing. At the same time, the processed battery decomposed parts are automatically classified and recycled, with a high recycling rate and no secondary pollution to the environment. At the same time, since the battery is fully automated from loading to final classification, the hazards of manual battery waste disposal are eliminated.

[0010] S4: Visual sorting on-line: After unloading, the battery is transported by the unloading conveyor line to the visual sorting on-line device, which collects the three-dimensional size and pole group position of the battery through vision, and adjusts the specific position of the battery in the Z-axis, Y-axis, and X-axis directions according to the visual collection results, so that the battery placed randomly after unloading can be transformed into a state facing the specified direction, and then transported to the next step for cutting;

[0011] S5: Four-step cutting and collection: The battery with one or two layers of electrode groups is disassembled and separated in steps, and the battery is disassembled into four major parts: upper cover, bottom plate, electrode group, and outer shell.

When the support plate unloading mechanism of the storage and unloading device opens the support plate below the storage bin, unloading begins; after the waste power batteries are online, the visual recognition measurement system in the visual sorting online device collects visual data and sequentially passes the batteries through the Z-axis, Y-axis, and X-axis direction sorting devices, and the batteries are sorted by the visual recognition measurement system in the visual sorting online device.

The classification and disassembly method and device of the present invention make the separated substances purer and reduce the secondary pollution to the environment during the separation process. The specific beneficial effects are as follows:

[0034] 1. High efficiency: The storage and unloading device and the visual sorting online device effectively solve the storage and unloading problems before the battery goes online, reduce the labor intensity, avoid environmental pollution, realize the automation process, and improve the efficiency of battery online and recycling.

[0035] 2. Wide range of applications. After going online, the machine vision recognition system will take the relevant dimensions of the power battery and feed it back to the main system. The main system will control the cutting of the head and tail, the upper and lower back cutting, and the upper and lower pushing to perform accurate operations according to the relevant dimensions of the battery.

[0036] 3. Component modularization and high interchangeability of parts. The small parts of each workstation are divided into different operations. If a small part is damaged, it will not affect the normal operation of other small parts, but the damaged small parts should be replaced in time; some parts of the small parts are public, which not only reduces the amount of tasks in the manufacturing process of the device, but also when the parts of the small parts need to be replaced, the types of parts that need to be replaced are relatively small, which has little impact on normal operations and high interchangeability.

[0037] 4. High safety and low pollution. The four-step cutting device can be operated in a closed environment. Humans are only responsible for supervising the control console. The human body does not come into contact with the battery, which can protect the staff well. In addition, during the four-step cutting process, acid will flow out and related harmful gases will be generated. The four-step cutting device is placed in a closed environment and checked and cleaned regularly. The pollution to the environment caused by the cutting process can be reduced to a minimum.

[0038] 5. High resource recovery rate. General manual crushing and sorting and semi-automatic crushing and sorting will cause the lead oxides, sulfuric acid, arsenic and other substances that need to be recycled to be wasted in the crushing and sorting process. However, after cutting and separating with the four-step cutting device, the lead oxides, sulfuric acid, arsenic and other substances that need to be recycled will not be wasted in the cutting and separation process. These substances will be concentrated on the upper cover poles and pole groups, and there will be a little residue on the outer shell, which will not cause waste of resources.

When the four-step cutting device has been working for a long time, the tool 3-1-1-6 will be worn, and the precision requirement of cutting the upper cover cannot be met at this time. Therefore, the hand wheel 3-1-1-4 is used to control the tool 3-1-1-6 to move down to make up for the wear of the tool 3-1-1-6 in the previous operation. The size of the pressing plate used is determined according to the size of a large number of waste power batteries collected, so that the size of the pressing plate should not be too small or too large.
