Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1As shown in the figure, this application discloses a cutting device for a battery casing, comprising: a body 100, a base 200, a cutting assembly 300, a first ejector cylinder 400, and a first driving member 500; the base 200 is disposed on the body 100; a slide rail 210 is provided on the base 200; the cutting assembly 300 is disposed on the base 200; the cutting assembly 300 includes a cutting chamber 310; the cutting chamber 310 is hollow and used to accommodate a battery; the cutting chamber 310 at least partially abuts against the battery casing; the first ejector cylinder 400 is slidably disposed on the slide rail 210 and coaxially disposed with the cutting chamber 310; the ejector cylinder is used to push the battery into the cutting chamber 310; the first driving member 500 is disposed on the base 200 and is drively connected to the first ejector cylinder 400.

[0022] Specifically, during the battery casing cutting process, the battery casing head is snapped into the cutting chamber 310, and then the first ejector cylinder 400 is slid, using the thrust of the first ejector cylinder 400 to push the entire battery into the cutting chamber 310, ensuring that the battery casing is completely cut by the cutting blades of the cutting chamber 310, so as to peel off the battery casing in large pieces, exposing the battery core, and completely separating the battery casing and the battery core, avoiding mixing of the battery casing and the battery core.

[0023] In one embodiment, both the cross-sectional shape of the first ejector cylinder 400 and the cross-sectional shape of the cutting chamber 310 are circular, and the diameter of the first ejector cylinder 400 is smaller than the diameter of the cutting chamber 310. Specifically, the cross-sectional shape of the cutting chamber 310 is circular, and the cross-sectional shape of the first ejector cylinder 400 is also circular, with the diameter of the first ejector cylinder 400 being smaller than the diameter of the cutting chamber 310, ensuring that the first ejector cylinder 400 can push the battery into the cutting chamber 310 during the battery pushing process.

[0024] like Figure 2 As shown, in this embodiment, the cutting device for the battery casing further includes a second ejector cylinder 600; the second ejector cylinder 600 is connected to the body 100 and is located on the side of the cutting assembly 300 opposite to the first ejector cylinder 400; the second ejector cylinder 600 is used to push the battery out of the cutting chamber 310.

[0025] Specifically, the second ejector cylinder 600 is connected to the main body 100 and is located on the side of the cutting assembly opposite to the first ejector cylinder 400, that is, the first ejector cylinder 400 and the second ejector cylinder 600 are respectively arranged on both sides of the cutting assembly. In actual use, the battery casing head is snapped into the cutting chamber 310, and then the first drive unit 500 is activated. The first drive unit 500 drives the first ejector cylinder 400 to slide on the slide rail 210 so that the first ejector cylinder 400 slides to contact the end of the battery exposed in the cutting chamber 310, and continues to slide to push the entire battery into the cutting chamber 310, whereby the cutting chamber 310 cuts the battery casing. Subsequently, the second ejector cylinder 600 moves toward the first ejector cylinder 400 to eject the cut battery casing from the cutting chamber 310.

[0026] In this application, the first ejector cylinder 400 and the second ejector cylinder 600 are respectively disposed on both sides of the cutting assembly 300, and the first ejector cylinder 400 and the second ejector cylinder 600 move towards each other, that is, the first ejector cylinder 400 pushes the battery into the cutting chamber 310, and the second ejector cylinder 600 ejects the battery from the cutting chamber 310. This facilitates the removal of the cut battery from the cutting chamber 310 so as to peel off the cut battery casing.

[0027] In this embodiment, a telescopic rod is provided at the end of the second ejector cylinder 600 near the cutting assembly 300; the telescopic rod is used to extend into the cutting chamber 310 and abut against the battery. Specifically, the telescopic rod is inserted into the cutting chamber 310 to accurately eject the cut battery from the cutting chamber 310. In actual use, the main body 100 is provided with a second driving member, the output shaft of which is connected to the telescopic rod. The length of the telescopic rod is adjusted by the second driving member to match the size and length of different batteries, ensuring that the second ejector cylinder 600 ejects the battery out of the cutting chamber 310. Similarly, the first driving member 500 drives the first ejector cylinder 400 and adjusts the distance between the first ejector cylinder 400 and the cutting assembly 300. When cutting batteries of different lengths, the smoothness of battery casing cutting is ensured by adjusting the distance between the first ejector cylinder 400 and the second ejector cylinder 600 and the cutting assembly 300.

[0028] like Figure 3 As shown, in one embodiment of this utility model, the cutting chamber 310 includes a first cutting chamber 311 and a second cutting chamber 312; the first cutting chamber 311 and the second cutting chamber 312 are arranged in a straight line and are spaced apart; a protective chamber 313 is provided between the first cutting chamber 311 and the second cutting chamber 312; wherein, the first cutting chamber 311 is used to cut the battery casing; and the second cutting chamber 312 is used to cut the battery top.

[0029] In practical use, the first cutting chamber 311 and the second cutting chamber 312 are arranged in a straight line and spaced apart, with a protective chamber 313 between them. When cutting the battery casing, the battery is first pushed into the first cutting chamber 311. As the battery passes through the first cutting chamber 311 and enters the protective chamber 313, the battery casing is cut. When the battery continues to be pushed through the protective chamber 313 and the top of the battery casing extends into the second cutting chamber 312, the second cutting chamber 312 cuts off the top of the battery casing. In this way, by setting the first cutting chamber 311 and the second cutting chamber 312 to cut the casing body and top of the battery casing, the battery casing can be peeled off in large pieces, ensuring the integrity of the battery core.

[0030] like Figure 4 and Figure 5 As shown, in this embodiment, the first cutting chamber 311 is provided with a first cutting channel 3110; the first cutting channel 3110 is provided with at least two first cutters 3111; the at least two first cutters 3111 are arranged along the circumferential direction of the first cutting channel 3110.

[0031] Specifically, the inner wall of the first cutting channel 3110 is provided with at least two first cutters 3111. The at least two first cutters 3111 are evenly arranged along the circumferential direction of the first cutting channel 3110, and the cutting edges of the first cutters 3111 are all facing the central axis of the first cutting channel 3110. With this design, when the battery passes through the first cutting channel 3110, the first cutters 3111 provided on the inner wall of the first cutting channel 3110 cut the battery casing along the first direction.

[0032] In actual production, the number of first cutters 3111 can be set to 2, 3, 4, or more. In this embodiment, there are four first cutters 3111, which are evenly spaced around the inner wall of the first cutting chamber 311. When the battery passes through the first cutting chamber 311, the four first cutters 3111 evenly cut the battery casing into four equal parts, removing the battery casing in large pieces and increasing the cutting speed. In addition, in actual production, the first cutting chamber 311 has different sizes, and the first cutting chamber 311 of different sizes has first cutting channels 3110 of different diameters. When cutting the battery, the first cutting chamber 311 of different diameters can be selected according to the size of the battery to ensure that the diameter of the first cutting channel 3110 matches the thickness of the battery. This ensures that the diameter of the first cutting chamber 311 is slightly smaller than the thickness of the battery, ensuring that the battery can pass smoothly through the first cutting channel 3110 and can be cut by the first cutters 3111 when passing through the first cutting channel 3110.

[0033] like Figure 6 and Figure 7 As shown, specifically, the inner wall of the second cutting chamber 312 is provided with a groove, and the second cutter 3121 is rotatably mounted on the groove. When the end of the battery extends into the second cutting chamber 312, the second cutter 3121 rotates and cuts around the end of the battery to cut off the top of the battery casing. In actual use, the second cutter 3121 is located at the end of the second cutting channel 3120 near the protective chamber 313, so that when the end of the battery extends into the second cutting chamber 312, the top of the battery casing can be cut off. In one embodiment, the second cutting chamber 312 is provided with a driving member, and the output shaft of the driving member is connected to the second cutter 3121 to drive the second cutter 3121 to rotate.

[0034] In this embodiment, the first cutter 3111 cuts the body of the battery casing from a first direction, and the second cutter 3121 rotates and cuts the head of the battery casing from a second direction. By cutting the battery casing in two directions, the battery casing can be cut in one operation to peel off large pieces of the battery casing.

[0035] In this embodiment, the first cutter 3111 has a triangular cross-sectional shape, and the second cutter 3121 has a fan-shaped cross-sectional shape. Specifically, the first cutter 3111 has a triangular cross-sectional shape, with the vertex of the triangular cutter facing the center of the first cutting channel 3110; the second cutter 3121 has a fan-shaped cross-sectional shape, and either the arc-shaped side or the vertical side of the fan-shaped cutter can be set as the cutting edge. When the battery passes through the first cutting channel 3110, the triangular cutter cuts the battery casing axially. As the battery continues to extend into the second cutting channel 3120, the second cutter 3121 rotates, cutting the battery casing head radially.

[0036] In actual production, the diameters of the first cutting channel 3110 and the second cutting channel 3120 are both matched to the diameter of the battery. Specifically, the diameter of the first cutting channel 3110 is slightly larger than the diameter of the battery, so that when the battery enters the first cutting channel 3110, the first cutter 3111, located on the inner wall of the first cutting channel 3110, can contact the battery casing, ensuring that the first cutter 3111 can cut the battery casing without cutting too deeply. The diameter of the second cutting channel 3120 is also slightly larger than the diameter of the battery, allowing the battery to smoothly enter the second cutting channel 3120, where the second cutter 3121 removes the top of the battery casing.

[0037] In this embodiment, the protective compartment 313 is provided with a connecting channel; the connecting channel is used to carry the battery; specifically, the connecting channel is coaxially arranged with the first cutting channel 3110 and the second cutting channel 3120. The protective compartment 313 is made of a high-temperature resistant material, such as stainless steel or alloy, and the inner wall of the connecting channel is coated with a fire-retardant coating. The protective compartment 313 serves as a transition device between the first cutting compartment 311 and the second cutting compartment 312. When the battery casing is cut in the first cutting compartment 311, it enters the protective compartment 313 for transition, and then re-enters the second cutting compartment 312 from the protective compartment 313 to cut the top of the battery casing, ensuring the safety of the cutting process.

[0038] In one embodiment, a plurality of first cutting channels 3110 and second cutting channels 3120 are provided. The plurality of first cutting channels 3110 are arranged along the circumferential direction of the first cutting chamber 311, and similarly, the plurality of second cutting channels 3120 are arranged along the circumferential direction of the second cutting chamber 312. In this way, each cutting channel can hold one battery for cutting, and multiple batteries can be cut at one time, thereby improving cutting efficiency.

[0039] In this embodiment, the battery casing head is the protruding end of the battery casing. Normally, this protruding end is the positive terminal of the battery. Therefore, during battery cutting, the protruding end of the battery casing is inserted into the first cutting chamber 311, and the first push-out cylinder 400 pushes the exposed end of the battery. Under the pushing force, the battery passes through the first cutting chamber 311, the protection chamber 313, and the second cutting chamber 312. The first cutting chamber 311 cuts the battery casing body, and the second cutting chamber 312 cuts the battery casing head. After cutting, the second push-out cylinder 600 pushes the battery out of the cutting chamber 310.

[0040] In this embodiment, the cutting assembly 300 further includes a limiting seat 320; the limiting seat 320 is disposed on the base 200; the limiting seat 320 is provided with an installation channel 321 for fixing the cutting chamber 310. In actual production, a fixing groove is evenly arranged around the inner wall of the installation channel 321, and a corresponding protrusion is also arranged around the outer surface of the cutting chamber 310. The protrusion is embedded in the fixing groove to fix the cutting chamber 310 on the installation channel 321. In some embodiments, the cutting chamber 310 can also be fixed on the installation channel 321 by means of screw connection or interference fit.

[0041] In summary, this utility model discloses a battery casing cutting device, comprising: a body, a base, a cutting assembly, a first ejector cylinder, and a first driving member; the base is disposed on the body; a slide rail is provided on the base; the cutting assembly is disposed on the base; the cutting assembly includes a cutting chamber; the cutting chamber is used to cut the battery casing; the first ejector cylinder is slidably disposed on the slide rail and coaxially disposed with the cutting chamber; the ejector cylinder is used to push the battery into the cutting chamber; the first driving member is disposed on the base and is drively connected to the first ejector cylinder. This application, by setting a first ejector cylinder, allows the battery to enter the cutting chamber, where the battery casing is cut to remove large pieces of the battery casing, thereby ensuring the integrity of the internal core of the battery. This solves the problem of existing batteries where the casing and core mix when the battery is broken, leading to difficulties in subsequent sorting.
