Description

Technical Field

[0001] The utility model belongs to the technical field of batteries, and particularly relates to a cutting machine for disassembling lithium batteries. Background Art

[0002] As batteries are used more and more widely, the demand for batteries is also increasing day by day. In order to reduce the cost of battery production and reduce environmental pollution, batteries are usually recycled. Since the exterior of used batteries has an outer shell and a cover plate, it is necessary to use a circular saw blade or wire cutting to cut the battery, or to cut the corresponding cover plate. In the prior art, the middle or bottom of the battery is pressed, the side of the battery to be cut is suspended, and then the cutter (or wire cutter) cuts off the suspended end of the battery. In the above process, due to the unilateral force on the battery, the battery is easily deformed. It is possible that the battery cell is over-extruded and difficult to remove, and it is also possible that the battery is compressed and short-circuited and catches fire. Utility Model Content

[0003] The utility model aims to provide a cutting machine for disassembling lithium batteries which can reduce hidden dangers in the cutting process.

[0004] To achieve the above-mentioned purpose, the utility model provides a cutting machine for disassembling lithium batteries, including a conveying mechanism for conveying batteries to be cut, a pressing mechanism and a saw blade mechanism are arranged above the conveying mechanism, the cutting machine also includes a clamping mechanism, and the clamping mechanism is arranged on the side of the conveying mechanism. The clamping mechanism includes a shell, a plurality of guide pillars, and a plurality of springs. A plurality of circular holes are arranged on the inner side of the shell, and the springs and the guide pillars are successively inserted into the circular holes. When the clamping mechanism presses the battery to be cut, the plurality of guide pillars are pressed to form a clamping structure that fully fits the end face of the battery to be cut, thereby limiting the up, down, left, and right degrees of freedom of the end face of the battery to be cut.

[0005] As an improvement of the above scheme, the clamping mechanism also includes a positive electrode sheet and a negative electrode sheet, and the positive electrode sheet and the negative electrode sheet are separately arranged at the bottom of the shell. The positive electrode sheet and the negative electrode sheet and a plurality of springs and a plurality of guide pillars on the corresponding sides can respectively form conductive electrodes, and a power-consuming device is connected between the two electrodes. When the clamping mechanism presses the battery to be cut, the clamping mechanism discharges the battery to be cut.

[0006] As an improvement of the above solution, a gap of 3 mm to 5 mm is set between the area corresponding to the positive electrode sheet and the area corresponding to the negative electrode sheet.

[0007] As an improvement of the above solution, the diameter of the guide pillar is 2-3 mm, and the distance between the centers of two adjacent guide pillars is 3-4 mm.

[0008] As an improvement of the above solution, a guide rail, a mounting bracket and a telescopic mechanism are provided at the bottom of the clamping mechanism, and the telescopic mechanism drives the clamping mechanism to approach or move away from the battery to be cut.

The saw blade mechanism includes a saw blade, a motor and a second lifting rod for driving the saw blade to rise and fall.

[0010] The utility model has the following beneficial effects: a plurality of guide posts can be independently contracted in the axial direction to form a flexible support surface that fully and comprehensively contacts the battery to be cut. By utilizing the characteristic that the guide posts only have axial freedom, adjacent guide posts support the ends of the battery to be cut, share the force, and reduce the deformation of the battery to be cut. After the positive and negative poles are set, the power-consuming equipment continuously consumes the power of the battery to be cut, making it in a low-voltage state, reducing the hazard of battery short circuit during the cutting process; since the two poles are on the same side, this solution is particularly suitable for cutting single-side pole batteries.
