Description

Technical Field

[0001] This utility model relates to the field of splitting devices, and in particular to a splitting device for recycling waste lithium iron phosphate batteries. Background Technology

[0002] A lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. The rated voltage of a single cell is 3.2V, and the charging cut-off voltage is 3.6V~3.65V.

[0003] During charging, some lithium ions in the lithium iron phosphate battery are released and transferred to the negative electrode via the electrolyte, where they embed into the carbon material. Simultaneously, electrons are released from the positive electrode and travel from the external circuit to the negative electrode, maintaining the chemical reaction balance. During discharging, lithium ions are released from the negative electrode and travel to the positive electrode via the electrolyte. At the same time, electrons are released from the negative electrode and travel from the external circuit to the positive electrode, providing energy to the surrounding environment.

[0004] Utility model patent CN221934980U discloses a device for fixing and disassembling waste lithium iron phosphate batteries. The device includes a main body, a fixing frame fixedly mounted on the outer side of the main body, an electric push rod fixedly mounted on the top of the fixing frame, a mounting plate on the inner surface of the fixing frame, a rotary motor fixedly mounted on the left side of the mounting plate, a sliding groove formed on the bottom surface of the mounting plate, a guide screw rotatably mounted inside the sliding groove, and top rods symmetrically fitted at the left and right ends of the guide screw. A battery body is mounted on the top of the main body. A fixing mechanism is set between the body and the main body of the device. Through the setting of a waste lithium iron phosphate battery fixing and disassembly device, the structural design of the fixing mechanism is used to fix the battery firmly and prevent the battery from shifting, which is conducive to the subsequent battery disassembly operation. However, when the device disassembles the top cover, the electric push rod retracts and the push rod gradually moves upward and drives the top cover to separate from the battery body. Since the top cover moves upward and is supported by two push rods, the staff needs to hold the top cover in advance when removing it, which is relatively troublesome and also poses a certain risk of falling.

[0005] Therefore, it is necessary to provide a new splitting device for recycling waste lithium iron phosphate batteries to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a splitting device for recycling waste lithium iron phosphate batteries.

The top of the mounting frame is on the same horizontal plane as the top of the mounting plate. The mounting frame is fixedly connected to the telescopic end of the electric cylinder. The second threaded rod is rotatably connected in the groove of the mounting frame. The second threaded rod has left and right threads at both ends. The two transmission frames are respectively threaded to the left and right threads of the second threaded rod. The two transmission frames are adapted to the groove size of the mounting frame. A clamping plate is fixedly connected to the top of each of the two transmission frames.

[0011] Preferably, the adjusting component includes a support frame, a third threaded rod, a movable plate, and a plug rod. The support frame is fixedly connected to the mounting frame, the third threaded rod is rotatably connected to the support frame, the movable plate is threadedly connected to the third threaded rod, and a plug rod is fixedly installed at the end of the movable plate.

[0014] Compared with related technologies, the dismantling device for recycling waste lithium iron phosphate batteries provided by this utility model has the following beneficial effects:

[0015] The second motor drives the second threaded rod to rotate, causing the two transmission frames to move closer to each other, thus clamping the top cover and main body of the lithium iron phosphate battery. During clamping, the auxiliary plate is contacted first, causing the spring to be compressed. Finally, the object being clamped comes into contact with the clamping plate, and the auxiliary plate applies force to the object under the action of the spring, increasing the clamping force.

[0016] After disassembly, the two clamping devices can be moved in opposite directions. At this time, the battery body and cover are mounted on the two mounting brackets, which can be removed directly by the staff. The clamping plate can also be moved to the appropriate position by the spring and auxiliary plate, so that the auxiliary plate applies a certain force to the cover, which enhances the stability of the cover after it is separated from the clamping plate. The staff can then remove the cover directly. Attached Figure Description

The two ends of the first threaded rod 5 are left-hand threads and right-hand threads, respectively. Two moving frames 2 are threadedly connected to the left-hand threads and right-hand threads of the first threaded rod 5, respectively. The first motor 4 is mounted on the worktable 1. The output end of the first motor 4 is fixedly connected to the first threaded rod 5. The guide rod 6 is fixedly connected to a groove in the worktable 1. The guide rod 6 moves through the two moving frames 2.

On a horizontal clamping device, the top cover of the lithium iron phosphate battery is placed on a horizontal clamping device without mounting plate 3. The top cover is located on mounting frame 8, and the battery body is located on another mounting frame 8. One end of the battery body rests on mounting plate 3. The second motor 10 drives the second threaded rod 9 to rotate, so that the two transmission frames 11 drive the two clamping plates 12 to move closer to each other, thereby achieving the clamping work of the top cover and battery body of the lithium iron phosphate battery. After disassembly, the two clamping devices can be moved in opposite directions. At this time, the battery body and the cover are mounted on the two mounting frames 8, and the staff can directly remove them.

The dimensions of the mounting plate 3 and the mounting frame 8 are adjusted according to the length of the main body of the lithium iron phosphate battery to be separated. Rotating the third threaded rod 14 moves the movable plate 15 on it, thereby moving the mounting plate 3 and improving the flexibility of the device during use. In addition, the clamping plate 12 can be moved to an appropriate position by the spring 18 and the auxiliary plate 19, so that the auxiliary plate 19 applies a certain force to the cover plate, which enhances the stability of the cover plate after it is separated from the clamping plate 12.

The two ends of the spring 18 are fixedly connected to the bracket 17 and the auxiliary plate 19, respectively. When clamping, the spring 18 first contacts the auxiliary plate 19, causing the spring 18 to be compressed. Finally, the object being clamped comes into contact with the clamping plate 12, and the auxiliary plate 19 applies force to the object being clamped under the action of the spring 18, thereby increasing the clamping force.
