[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] A lithium-ion battery cutting device comprises a collection box 11, a partition plate 15, a cutting mechanism, a clamping mechanism, a synchronization mechanism, an adjustment mechanism and a protection mechanism; the cutting mechanism comprises a cutting shaft 13 and a cutting knife 14; the clamping mechanism comprises a bearing 31, an extrusion plate 32, a limiting square rod 33 and a placement slot 61; the synchronization mechanism comprises a reduction motor 21, a driving sprocket 41 and a driven sprocket 42; the adjustment mechanism comprises an extension frame plate 51 and a bidirectional lead screw 52; the protection mechanism comprises a slide bar 71, a limiting slot 72 and an arc plate 73;

[0026] An L-shaped partition plate 15 is fixed to the upper end of the collecting box 11, and the partition plate 15 divides the inner cavity of the collecting box 11 into a cutting space and a filtering space. A horizontal plate of the partition plate 15 is provided with a plurality of filter holes arranged in an array in the thickness direction thereof, and the filter holes connect the cutting space and the filtering space. A horizontally arranged cutting shaft 13 is rotatably provided in the cutting space, and a cutting knife 14 is coaxially fixedly mounted on the outer side of the cutting shaft 13.

[0027] A drain pipe 12 is provided at the bottom of the collecting box 11, and the drain pipe 12 is connected to the cutting space. The collecting box 11 provides a storage space for the electrolyte in the lithium-ion battery. A valve is provided on the drain pipe 12. After the valve is opened, the electrolyte in the lithium-ion battery in the collecting box 11 can be discharged through the drain pipe 12.

[0028] The cutting shaft 13 is rotated to drive the cutting blade 14 to rotate, thereby realizing the cutting process of the lithium-ion battery, and then the cut lithium-ion battery is placed on the horizontal plate of the partition plate 15, and the residual electrolyte in the lithium-ion battery falls into the cutting space through the filter hole, and the lithium-ion battery body remains on the partition plate 15, thereby realizing the automatic separation of the lithium-ion battery body and the electrolyte and the automatic recovery of the electrolyte.

[0029] The upper ends of the two side plates of the collecting box 11 are fixedly connected to the outer rings of the corresponding bearings 31, and the inner rings of each bearing 31 are slidably mounted on the outer sides of the corresponding limiting square rods 33. The two limiting square rods 33 are correspondingly arranged and the opposite ends of the two limiting square rods 33 are coaxially fixedly connected to the middle of the corresponding extrusion plate 32.

[0030] A plurality of lithium-ion batteries are placed between two extrusion plates 32 so that both ends of the lithium-ion batteries are in contact with the corresponding extrusion plates 32 respectively, and the two extrusion plates 32 are used to extrude the plurality of lithium-ion batteries. The bearings 31 are used to rotate the extrusion plates 32, thereby driving the lithium-ion batteries to rotate, so that the plurality of lithium-ion batteries are in contact with the rotating cutting blade 14 in turn, thereby realizing the cutting process of the plurality of lithium-ion batteries.

[0031] A plurality of placement slots 61 are provided on the opposite surfaces of the two extrusion plates 32 in a one-to-one correspondence. The plurality of placement slots 61 are evenly distributed along the circumference of the corresponding extrusion plates 32. A notch is provided at the outer end of each placement slot 61. The two ends of the lithium-ion battery are respectively placed in the corresponding two placement slots 61 to limit the lithium-ion battery and prevent it from falling off from between the two extrusion plates 32.

[0032] The cutting shaft 13 is driven to rotate by a reduction motor 21, and the reduction motor 21 is fixedly arranged on the collecting box 11. The two ends of the cutting shaft 13 are coaxially fixedly connected with the corresponding driving sprockets 41, and each of the driving sprockets 41 is connected with the corresponding driven sprocket 42 through a corresponding chain transmission. Each of the driven sprockets 42 is slidably mounted on the outer side of the corresponding limiting square rod 33 and is fixedly connected with the inner ring of the bearing 31.

[0033] The reduction motor 21 is connected to the power supply through a wire and a switch. After the reduction motor 21 is started, it drives the cutting shaft 13 to rotate, and then drives the cutting knife 14 and the two driving sprockets 41 to rotate at the same time. The two driving sprockets 41 drive the two driven sprockets 42 to rotate, and the two driven sprockets 42 respectively drive the inner rings of the corresponding bearings 31 to rotate, and finally drive the two extrusion plates 32 to rotate, ensuring that when the cutting knife 14 rotates, multiple lithium-ion batteries rotate synchronously.

[0034] The diameter of the driving sprocket 41 is smaller than that of the driven sprocket 42, which has a deceleration effect to ensure that the cutting knife 14 can rotate quickly, while the multiple lithium-ion batteries fixed between the two extrusion plates 32 rotate slowly, so that the multiple lithium-ion batteries slowly contact with the fast-rotating cutting knife 14, and the lithium-ion batteries are cut in sequence.

[0035] The two side walls of the collecting box 11 are fixedly connected to one end of the corresponding extension frame plate 51, and the other ends of the two extension frame plates 51 are correspondingly rotatably connected to the two ends of the bidirectional lead screw 52, ​​and the two ends of the bidirectional lead screw 52 are respectively screwed to the corresponding limiting square rod 33.

[0036] By rotating the bidirectional lead screw 52, ​​the two extrusion plates 32 can be driven to slide inward or outward at the same time, thereby changing the distance between the two extrusion plates 32, so that lithium-ion batteries of different lengths can be placed between the two extrusion plates 32. The distance between the two extrusion plates 32 can be changed according to the length of the lithium-ion battery to be cut.

[0037] The two side plates of the collecting box 11 are slidably connected to the corresponding horizontally arranged sliding rods 71, and the inner ends of the two sliding rods 71 ​​are fixedly connected to the outer walls of the corresponding arc-shaped plates 73, and the outer end of each arc-shaped plate 73 is fixed with a limiting groove 72, and each extrusion plate 32 is placed in the corresponding limiting groove 72, and each arc-shaped plate 73 is respectively mounted on the outer side of the corresponding placement groove body 61, and the opening end of each arc-shaped plate 73 is arranged corresponding to the filtering space.

[0038] During operation, the extrusion plate 32 rotates in the corresponding limiting groove 72, and the slide bar 71 ensures the lateral position change of the extrusion plate 32. The arc plate 73 is used to limit the lithium-ion battery to be cut and the cut lithium-ion battery. When the lithium-ion battery is cut and rotated to the open end of the arc plate 73, it will automatically fall from the corresponding placement groove 61 into the filtering space under the action of gravity and centrifugal force.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent conditions of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
