Problems solved by technology

1. Environmental protection: the positive electrode material of the lithium battery contains heavy metal elements such as nickel, cobalt, manganese, lithium, etc. These heavy metal elements will pollute the environment and water; the carbon materials and graphite in the negative electrode material will cause dust pollution; in addition , the electrolyte of lithium batteries contains toxic chemical components, which can also cause fluorine pollution
2. Resource saving: Lithium batteries contain a large amount of metal elements, such as nickel and graphite, which are more abundant in my country, but metal elements such as cobalt are scarce in my country; China has a lot of lithium elements in absolute content, but mining is relatively difficult, generally They are all distributed in mines with relatively difficult conditions; the content of magnesium ions in salt lake lithium is relatively high, and it is very difficult to extract lithium
However, during the recycling and dismantling of lithium batteries, there may be a large number of bulges inside the lithium battery, the circuit control board, and the extrusion and offset of various components may not be directly seen from the appearance of the battery box.
Traditional manual violent dismantling not only easily damages the components inside the battery box, but also reduces the recycling rate of the internal components of the lithium battery, and also poses a major safety hazard

Embodiment 1

[0029] see figure 1 , figure 2 , image 3 , Figure 4 , after the battery box 4 is placed on the bearing platform 1, the side clamping mechanism 3 is used to drive the clamping push plate 301 to "positive position" the battery box 4. The side clamping mechanism 3 can use a hydraulic device. It is necessary to pay attention to ensure the hydraulic synchronization of the two side clamping mechanisms 3, and ensure that the driving force and the advancing [final] distance of the hydraulically driven clamping and propelling plates 301 on both sides are the same.

[0030] The rotating device 2 below the carrying table 1 can use a servo motor to rotate the carrying table 1 so that the side corresponding to the battery cover 5 faces the cutting piece 22 of the cutting device 12 .

[0031] The lifting device 9 can be fixedly installed on the corresponding base frame. The lifting device 9 is configured with a coding module for sensing and detecting the lifting distance of the lifti...

Embodiment 2

[0035]In the present invention, the specific function meaning of the initial distance: the cutting device 12 moves forward to ensure that the cutting piece 22 of the cutting device 12 is in contact with the outer side of the battery cover 5; moving the initial distance backward, the cutting piece 22 does not contact the battery when turning Cover 5 comes into contact.

[0036] see figure 1 , Figure 5 , when the initial distribution of the cutting device 12 is performed on the periphery of the battery cover 5, the figure 1 A set of pair-side distribution structures in Figure 5 The structure of the adjacent side distribution in the middle.

[0037] use figure 1 In the distribution mode of the middle cutting device 12, the rotating device drives the bearing platform 1 to rotate 90° during each round cutting process, and two parameter values ​​must be set for the initial distance between the two longitudinal moving devices 11 to advance the cutting device 12. The initial...

Embodiment 3

[0041] see figure 1 , figure 2 , image 3 , In the present invention, after completing one cycle of cutting, the lifting mechanism 8 attempts to lift the battery cover 5 once. If the lifting force is too large or the battery cover 5 cannot be lifted under the set lifting force The ring side of the cover 5 has not been completely cut, or the strong sealant layer between the inner side of the battery cover 5 and the battery box 4 has not been cut off. The layer is bonded and cured, and the adhesion is large], sometimes it is necessary to cut to the inner side wall surface of the casing of the battery box 4 to lift the battery cover 5, and then to open the battery cover 5.

[0042] In the present invention, when the lifting mechanism 8 lifts the hook upward, the high stroke position of the hook 7 moving upward is set at a position where the battery cover 5 and the battery box 4 can be separated [after the battery cover 5 and the battery box 4 are cut] . For example, after t...

Abstract

The invention discloses a lithium battery linear sensing detection primary dismantling device and method, and relates to the technical field of lithium battery recycling. In the present invention: a set of opposite sides of the carrying platform is fixedly installed with a side clamping mechanism, the upper end of the hook is connected with a lifting mechanism, and the lifting mechanism is configured with a power device for driving the connecting hook and a sensor for sensing and detecting the magnitude of the upward pulling force. A module; a set of lifting devices are fixed on the periphery of the bearing platform, a lateral movement device is fixedly installed on the upper side of the lifting platform, and the longitudinal movement device drives and connects the cutting device. The present invention cuts and removes the difficult-to-remove lithium battery battery cover by adopting multiple progressive encircling cutting methods, and uses the lifting mechanism to lift the battery cover after each encircling cutting is completed by gradually increasing the depth of multiple cuts Try to effectively avoid direct damage to the internal battery bulge, unknown motherboard location, etc., which is safe and can improve the recyclability of the internal components of the used lithium battery.

Description

technical field [0001] The invention relates to the technical field of lithium battery recycling, in particular to a linear sensing detection type preliminary dismantling device and method for a lithium battery. Background technique [0002] The cascade utilization and recycling of lithium batteries are mainly based on environmental protection, resource conservation, and favorable availability. Figure 3 aspect. 1. Environmental protection: The positive electrode material of lithium battery contains heavy metal elements such as nickel, cobalt, manganese, lithium, etc. These heavy metal elements will pollute the environment, water, etc.; carbon material, graphite, etc. in the negative electrode material will cause dust pollution; in addition , The electrolyte of lithium batteries contains toxic chemical components, which can also cause fluorine pollution. 2. Resource saving: Lithium batteries contain a large amount of metal elements, such as nickel and graphite in my country...
