Description

Technical Field

[0001] The present invention relates to the technical field of battery module recycling equipment, and particularly relates to a battery module disassembling device. Background Art

[0002] In recent years, with the continuous popularization of new energy vehicles, the demand for battery modules has also been increasing. And the first batch of new energy vehicles put into use earlier are also gradually being retired. Therefore, how to disassemble and recycle the battery modules in new energy vehicles has become a direction that people are gradually concerned about.

[0003] When the existing battery modules are disassembled, generally a mechanical (hard) cutter is used to cut the battery housing to separate the battery housing from the inner core. After long-term cutting, the cutting tool will generate overheating. When the exhaust gas or electrolyte leaking from the disassembled battery inner core encounters the overheated tool, it is extremely easy to catch fire or even explode. Therefore, there are certain safety hazards in traditional disassembling equipment; and the existing water jet cutting equipment generally only has a cutting function and cannot peel off the battery housing during the cutting process, which is not conducive to the disassembly and separation of the battery housing and the inner core; at the same time, because most battery modules are square structures, the water jet cutting equipment needs to be positioned before cutting each side of the battery, and the operation is relatively cumbersome, reducing the disassembly rate of the battery module.

Since the battery module is generally a rectangular structure, the contact point between the battery module and the water outlet end of the water jet 62 will change during rotation. In order to ensure that the cutting depth of the water jet 62 remains consistent during the rotation of the battery module, the setting of the connecting member 64 enables the water jet 62 to synchronously expand and contract with the elastic telescopic end of the positioning member 63, ensuring the cutting depth of the water jet 62 during the rotary cutting of the battery module and avoiding the need for repeated positioning operations when the water jet 62 cuts other sides of the battery; while the peeling member 61 will insert into the slot generated by cutting during the cutting of the water jet 62 (that is, when the battery module rotates to make the cutting slot of the water jet 62 rotate to the peeling member 61, the stripping rod 612 is reset upward under the influence of the torsional spring resilience force and the bayonet at the top of the stripping rod 612 is clamped into the upper part of the cutting slot), and as the battery module continues to rotate, the peeling member 61 makes a spiral movement along the outer circumference of the battery module, thereby separating the outer shell and the inner core of the battery module (peeling the battery shell upward by the stripping rod 612), realizing the disassembly between the outer shell and the inner core of the battery module; when the water jet 62 cuts the battery module, it can take away the debris, electrolyte and heat generated by cutting, avoiding the phenomenon of combustion and explosion during the cutting process of the battery module and improving the safety of the disassembly of the battery module; at the same time, the filter box 3 can filter the battery shells and large-particle battery debris falling during the disassembly process, so that the battery shells and large-particle battery debris can stay in the filter box 3, and the cutting water body and the flushed electrolyte can pass through the filter box 3 to reach the bottom end inside the disassembly box 1, realizing the classification of the outer shell, electrolyte and water body;

[0041] As Figure 1-3As shown, in this embodiment, the clamping mechanism 2 includes a clamping plate 21, a first telescopic column 22, a fixing frame 23 and a tray 24; the tray 24 is connected to the driving member 8; the fixing frames 23 are symmetrically arranged on the outer circumference of the tray 24; the first telescopic columns 22 are fixed on the fixing frames 23, and the telescopic ends of the first telescopic columns 22 face the top of the tray 24.

Among them, the first telescopic columns 22 fixed on the tray 24 through the fixing frames 23 can adjust the distance between the clamping plates 21 through their own telescopic activities, so that the clamping plates 21 can synchronously clamp or loosen the battery module to be disassembled placed on the tray 24, realizing the clamping and fixing of the battery module and ensuring the stability of the battery module during disassembly. The tray 24 can be a mesh structure plate to ensure that the sprayed water body of the water knife 62 can pass through the tray 24 to reach the filter box 3 and the bottom of the box body 11, realizing the separation of the water body from the battery shell and the reuse of the water body.

[0042] As Figure 1 , 2 shown, in this embodiment, the driving member 8 includes a reducer 81 and a motor 82; the motor 82 is connected to the base 4, the reducer 81 is fixed to the output end of the motor 82, and the tray 24 is fixed to the output shaft of the reducer 81.

[0044] As Figure 1-9As shown in the figure, in this embodiment, the positioning member 63 includes an adjusting end 631, a screw 632, a fixed sleeve 633, a fixed rod 634, a positioning rod 635, a spring 636, a positioning protrusion 637, and a connecting rod 638; the fixed sleeve 633 is fixed on one side of the fixed rod 634, and the top end of the fixed rod 634 is connected to the bottom of the mounting seat 53; the screw 632 and the fixed rod 634 are respectively inserted into the two ends of the fixed sleeve 633, and the screw 632 and the fixed rod 634 are movably connected; the adjusting end 631 is fixed at one end of the screw 632 away from the fixed sleeve 633; the positioning protrusion 637 is fixed at one end of the fixed rod 634 away from the fixed sleeve 633, and the spring 636 is sleeved outside the positioning rod 635 between the fixed sleeve 633 and the positioning protrusion 637, so that when the adjusting end 631 rotates, it can drive the screw 632 to telescopically rotate at one end of the fixed sleeve 633 and push the positioning rod 635 to slide along the fixed sleeve 633, changing the distance between the fixed sleeve 633 and the positioning protrusion 637; in this embodiment, a connecting column 6321 is provided at one end of the screw 632 away from the adjusting end 631, and a clamping block 6322 is provided at one end of the connecting column 6321. The clamping block 6322 is one of a "one" shape, a "person" shape, a "cross" shape, and a "*" shape; preferably a "cross" shape; a guiding groove 6351 matching the shape of the clamping block 6322 is provided in the inner cavity of the positioning rod 635, so that when the screw 632 rotates, it can drive the positioning rod 635 to rotate and telescopically adjust, and when the positioning protrusion 637 at one end of the positioning rod 635 is squeezed, it can be not affected by the screw 632, so that the positioning rod 635 can retract into the inner cavity of the fixed sleeve 633; among them, after the fixed sleeve 633 is connected to the mounting seat 53 through the fixed rod 634, it can be kept fixed. There is a through hole in the fixed sleeve 633. The through hole is a threaded section near the screw 632 and a smooth section near the positioning rod 635, so that both the screw 632 and the positioning rod 635 can be movably adjusted in the fixed sleeve 633; and the adjusting end 631, the screw 632, the positioning rod 635, the spring 636, and the positioning protrusion 637 constitute the elastic telescopic end of the positioning member 63. Therefore, when the positioning member 63 needs to elastically contact and position with the battery module housing through the elastic telescopic end, the adjusting end 631 can be rotated to drive the screw 632 to telescopically rotate at one end of the fixed sleeve 633. And because a clamping block 6322 with a special shape is provided on the connecting column 6321 at one end of the screw 632, and a guiding groove 6351 matching the shape of the clamping block 6322 is provided in the positioning rod 635, when the screw 632 rotates, it can drive the positioning rod 635 to synchronously rotate and telescopically adjust, changing the distance between the fixed sleeve 633 and the positioning protrusion 637, and further enabling the elastic telescopic end (the positioning protrusion 637 squeezes the spring 636) of the positioning member 63 to elastically abut against the housing of the battery module;When the battery module rotates, the contact position between the battery module housing and the positioning protrusion 637 changes, and the force exerted by the positioning protrusion 637 on the spring 636 also changes. Therefore, the positioning rod 635 slides telescopically along the through-hole under the action of the spring 636 without affecting the position of the screw rod 632. At this time, when the positioning protrusion 637 expands and contracts, it will drive the connecting rod 638 to expand and contract synchronously, thereby causing the connecting member 64 to slide telescopically in the chute 531, realizing the synchronous telescopic adjustment of the water knife 62, so as to ensure that the cutting position (i.e., the cutting depth) of the water knife 62 remains consistent when the battery module rotates, avoiding the need for repeated positioning operations when the water knife 62 cuts other sides of the battery module;

[0045] As Figure 1 , 2 shown, in this embodiment, the liquid pumping assembly 7 includes a first water inlet pipe 71, a spring tube 72, a second water inlet pipe 73 and a water pump 74; the water pump 74 is connected to the base of the water knife 62, a balance rod is provided at the bottom of the sliding seat 51, and the first water inlet pipe 71 is connected between the balance rod and the water pump 74; the second water inlet pipe 73 is vertically arranged in the inner cavity of the box body 11; the spring tube 72 is connected between the first water inlet pipe 71 and the second water inlet pipe 73; wherein, the first water inlet pipe 71, the spring tube 72 and the second water inlet pipe 73 can form a water inlet channel to realize the water inlet of the water pump 74, so that the water pump 74 can pump the water body inside the disassembly box 1 into the base of the water knife 62, so that the water knife 62 can have enough water body for spraying, and then generate a cutting water column to cut and disassemble the rotating battery module; the setting of the spring tube 72 can enable an elastic water delivery channel between the first water inlet pipe 71 and the second water inlet pipe 73, so that when the mounting frame 5 drives the water knife 62 to move up and down, it will not affect the water supply of the water knife 62;

[0046] In summary, for a battery module disassembly device provided by the present invention, the clamping mechanism 2 is used to clamp the battery module, so that the mounting frame 5 can adjust the height of the water jet cutting member 6 according to the height dimension of the battery module, making the elastic telescopic end of the positioning member 63 of the water jet cutting member 6 elastically contact with the outer shell of the battery module, and making the peeling member 61 abut against the surface of the battery module outer shell, so that the positioning member 63 can be used as the positioning end of the water jet 62 for initial positioning to ensure the cutting position and cutting direction of the water jet 62; the driving member 8 drives the clamping mechanism 2 to rotate, and the liquid pumping assembly 7 pumps the water in the disassembly box 1 into the water jet 62 of the water jet cutting member 6. When the battery module rotates, the mounting frame 5 can drive the water jet 62 to descend, and the water column sprayed by the water jet 62 cuts the battery module in a downward spiral shape. The elastic telescopic end of the positioning member 63 and the connecting member 64 are provided, so that the water jet 62 can synchronously expand and contract with the elastic telescopic end of the positioning member 63, ensuring the cutting depth of the water jet 62 when rotating and cutting the battery module, and avoiding the need for repeated positioning operations when the water jet 62 cuts other sides of the battery; the peeling member 61 will be inserted into the slot generated by cutting during the cutting of the water jet 62, and as the battery module rotates continuously, the peeling member 61 moves in a spiral shape along the outer circumference of the battery module, thereby separating the outer shell and the inner core of the battery module to achieve the disassembly between the outer shell and the inner core of the battery module; when the water jet 62 cuts the battery module, it can take away the chips, electrolyte and heat generated by cutting, avoiding the phenomenon of combustion and explosion during the cutting of the battery module and improving the safety of battery module disassembly; at the same time, the filter frame 3 can filter the battery outer shell and large particle battery chips that fall during the disassembly process, so that the battery outer shell and large particle battery chips can remain in the filter frame 3, and the cutting water body and the flushed electrolyte can pass through the filter frame 3 to reach the bottom end of the disassembly box 1, realizing the classification of the outer shell, electrolyte and water body.
