[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a dismantling device for lithium battery production and processing, characterized in that it includes a housing 1, a workbench 102 disposed inside the housing 1, a three-axis robotic arm 103 located above the workbench 102, a multi-functional tool quick-change head 104 installed at the end of the robotic arm, a dust removal system 2 disposed above the housing 1, and an electrolyte recovery device 3 disposed at the bottom of the workbench 102.

[0028] First, the lithium battery to be disassembled is placed at disassembly station 4 on the workbench 102 inside the housing 1. After the device is started, the adaptive clamping mechanism begins to work. The housing 1 structure allows the disassembly process to be carried out in a closed environment, reducing the impact of dust and harmful gases on operators. The magnetic connection of the multi-functional tool quick-change head 104 not only makes tool changing convenient but also facilitates tool disassembly and maintenance. The modular design of the metal dust separator 202 and the vacuum adsorption tank 303 makes the cleaning and maintenance of dust and electrolyte recovery components more convenient, reducing the later operation and maintenance costs of the device.

[0029] The workbench 102 is provided with a disassembly station 4, and the disassembly station 4 is equipped with an adaptive clamping mechanism. The adaptive clamping mechanism includes a liftable positioning groove 401, pneumatic push rods 402 symmetrically distributed on both sides of the positioning groove 401, and an arc-shaped pressure plate 403 at the end of the pneumatic push rods 402.

[0030] The height-adjustable positioning slot 401 automatically adjusts to a suitable position according to the height of the lithium battery, achieving initial positioning. Subsequently, the pneumatic push rods 402, symmetrically distributed on both sides of the positioning slot 401, extend synchronously, driving the arc-shaped pressure plate 403 at its end to move closer to the lithium battery. The pressure sensor inside the arc-shaped pressure plate 403 detects the clamping force in real time. When the pressure reaches a preset threshold, the pneumatic push rods 402 stop moving, ensuring that the lithium battery is stably clamped and not damaged, adapting to the clamping requirements of lithium batteries of different specifications.

[0031] The multi-functional tool quick-change head 104 integrates a laser cutter, a pneumatic gripper, and an ultrasonic vibrating knife, and is detachably connected to a robotic arm via a magnetic interface 106.

[0032] An external control unit controls the movement of the three-axis robotic arm 103 based on positioning data. The multi-functional quick-change tool head 104 at the end of the robotic arm enables rapid tool switching via a magnetic interface 106, adapting to different disassembly requirements: when disassembling the lithium battery casing, it switches to a laser cutter for precise laser cutting to create a damage-free opening; after the casing is opened, it switches to a pneumatic gripper to smoothly grasp the casing and move it to a designated area; for separating internal components such as electrodes and separators, it switches to an ultrasonic vibrating knife, using ultrasonic vibration to achieve efficient component separation and reduce material damage. Throughout the disassembly process, the three-axis movement of the robotic arm ensures operational flexibility and precision, while the magnetic interface 106 significantly shortens tool change time and improves disassembly efficiency.

[0033] The dust removal system 2 includes a vacuum cleaner 201 and a metal dust separator 202. The suction port of the vacuum cleaner 201 extends to the top of the housing 1 and is connected to the metal dust separator 202 through a pipe.

[0034] Metal dust generated during disassembly is handled in real-time by dust removal system 2: the vacuum cleaner 201 above the housing 1 is positioned with its suction inlet facing the disassembly station 4, sucking in the dust and transporting it through pipes to the metal dust separator 202. This separator uses a multi-stage cyclone separation structure, utilizing centrifugal force to achieve initial separation of metal dust. The separated exhaust gas then passes through a HEPA filter structure to further remove fine dust, ensuring emissions meet standards. The multi-functional tool quick-change head 104 integrates a laser cutter, pneumatic grippers, and ultrasonic vibrating knife. It achieves quick tool disassembly and replacement via magnetic interface 106, avoiding the tedious manual tool changing required in traditional devices and significantly shortening the disassembly cycle.

[0035] Furthermore, the workbench 102 is equipped with a liquid nitrogen spray pipe 107, which is connected to an external liquid nitrogen supply unit and forms a spray port on one side of the disassembly station 4.

[0036] To address issues such as electrode adhesion and sealant curing that may occur during lithium battery disassembly, the liquid nitrogen spray pipe 107 on the workbench 102 is activated. Liquid nitrogen is supplied through an external liquid nitrogen supply unit and sprayed from the spray nozzle on one side of the disassembly station 4 to perform low-temperature treatment on the key disassembly parts of the lithium battery, making the electrode material brittle and reducing the performance of the sealant, thus facilitating subsequent separation.

[0037] The low-temperature embrittlement effect of liquid nitrogen spraying, combined with the vibration separation technology of ultrasonic vibrating knife, reduces disassembly resistance, improves disassembly efficiency, reduces mechanical damage to materials, and increases the utilization rate of recyclable materials.

[0038] Furthermore, a pressure sensor is provided on the inner side of the arc-shaped pressure plate 403.

[0039] The adaptive clamping mechanism, combined with a pressure sensor, can automatically adjust the clamping force and positioning height according to the lithium battery specifications, adapting to the disassembly requirements of different lithium battery models and solving the problems of uncontrollable clamping force and poor versatility of traditional devices. The visual positioning module 105 consists of an infrared camera and a laser rangefinder, realizing visualized and precise positioning of the disassembly location. Combined with the flexible movement of the three-axis robotic arm 103, the disassembly error is controlled within a very small range, greatly improving the disassembly accuracy, and is especially suitable for the separation of precision components inside lithium batteries.

[0040] Furthermore, the Z-axis end of the three-axis robotic arm 103 is integrated with a visual positioning module 105 that is connected to an external control unit. The visual positioning module 105 includes an infrared camera and a laser rangefinder arranged coaxially.

[0041] The visual positioning module 105 at the end of the Z-axis of the three-axis robotic arm 103 starts working. The infrared camera captures the appearance of the lithium battery and the disassembly marks, and the laser rangefinder accurately measures the distance parameters. Both transmit the data to the external control unit to complete the precise positioning of the disassembly position and provide data support for the robotic arm's movements.

[0042] Furthermore, the electrolyte recovery device 3 includes a funnel-shaped collection tank 301 located at the bottom of the dismantling station 4 and a conduit 302 connected to the collection tank. The end of the conduit 302 is provided with a vacuum adsorption tank 303 filled with inert adsorption material.

[0043] The electrolyte in the lithium battery is collected through the funnel-shaped collection tank 301 at the bottom of the workbench 102 and flows into the vacuum adsorption tank 303 filled with inert adsorption material through the conduit 302. The inert adsorption material can effectively adsorb harmful components in the electrolyte. The vacuum environment accelerates the adsorption process, realizes the safe recycling of electrolyte, and avoids environmental pollution.

[0044] The electrolyte recovery device 3, through a funnel-shaped collection tank 301 and an inert adsorption vacuum tank, achieves full-process collection and adsorption treatment of the electrolyte, avoiding soil and water pollution caused by electrolyte leakage. At the same time, the precise disassembly method reduces material loss, keeping recyclable components such as the metal casing and electrodes in the lithium battery relatively intact, facilitating subsequent resource reuse and improving resource recycling efficiency.

[0045] Furthermore, the metal dust separator 202 is a multi-stage cyclone separation structure, and a HEPA filter structure is connected in series at the outlet end of the metal dust separator 202.

[0046] The dust removal system 2 adopts a dual purification structure of "multi-stage cyclone separation + HEPA filtration", which can efficiently capture metal dust generated during the dismantling process. The dust recovery rate is high and the exhaust emissions meet environmental protection standards, solving the problem of serious dust pollution in traditional dismantling.

[0047] Furthermore, the arc-shaped pressure plate 403 is embedded with a PTC heating element, and the heating temperature is set to 40℃-60℃.

[0048] If it is necessary to soften the sealant in a specific area, the PTC heating element embedded in the arc-shaped pressure plate 403 will be activated to stabilize the temperature within a safe range of 40℃-60℃, thus assisting in disassembly.

[0049] Furthermore, the enclosure 1 is equipped with an observation window 101 made of double-layer explosion-proof glass. A conductive grid is embedded between the double-layer explosion-proof glass, and the outer layer of glass is coated with an anti-fog coating.

[0050] The double-layered explosion-proof glass observation window 101 on the enclosure 1 provides operators with a real-time monitoring view. The embedded conductive mesh prevents electrostatic interference, and the outer anti-fog coating ensures clear observation. The design of the double-layered explosion-proof glass observation window 101, the conductive mesh, and the inert adsorption material ensures the safety of the disassembly process from the aspects of operation monitoring, electrostatic protection, and hazardous material handling, avoiding risks such as electrolyte leakage and dust explosion.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
