Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery technology, specifically to a tooling for disassembling and breaking open the casing of a cylindrical battery. Background Technology

[0002] Currently, in the lithium battery production process, the cells are typically welded to the current collectors and then placed into the casing. After the cells are installed, the casing is welded to the cover plate for sealing. Following sealing, processes such as soaking, pre-charging, and charging / discharging are required. During these processes, abnormal batteries are often disassembled to check the internal interface and identify any abnormalities. Therefore, battery disassembly is a necessary and frequent operation in battery production. Existing disassembly methods typically use tools such as diagonal pliers, needle-nose pliers, and steel knives. These methods can easily puncture the internal cells, causing sparking and potential finger cuts, and require a high level of skill from the operators. Utility Model Content

[0022] like Figures 1 to 6As shown, a cylindrical battery disassembly and casing breaking tool includes: a tool body with a handle 1 at its tail, an upper fixing plate 2 and a lower fixing plate 3 at its head, a mounting groove between the upper fixing plate 2 and the lower fixing plate 3, and through holes in both the upper fixing plate 2 and the lower fixing plate 3 communicating with the mounting groove. Gear teeth are provided in the through holes of the upper fixing plate 2, specifically, gear teeth are provided in the circumferential direction of the through holes of the upper fixing plate 2. A rotating mechanism is installed in the mounting groove and is capable of rotating within the mounting groove. The rotating mechanism has ratchet teeth that mesh with the gear teeth of the upper fixing plate 2, specifically, the rotating mechanism is capable of rotating relative to the upper fixing plate 2. A battery receiving through hole is provided at the center of the rotating mechanism, communicating with the through hole of the lower fixing plate 3, allowing the cylindrical battery to be inserted into the battery receiving through hole from below the tool body. The rotating mechanism also includes a cutting tool assembly, which includes a blade 10 extending radially to the battery receiving through hole. The upper fixing plate 2 also has a fixing groove communicating with the mounting groove. A reversing mechanism is provided in the fixing groove. This reversing mechanism works in conjunction with ratchet teeth to limit the unidirectional rotation of the rotating mechanism. Specifically, the reversing mechanism and ratchet teeth form a ratchet mechanism, which limits the rotation of the rotating mechanism to a certain direction. When it is necessary to disassemble and break the casing of the cylindrical battery, insert the cylindrical battery into the battery through hole, adjust the reversing mechanism so that the rotating mechanism can rotate in a certain direction, and then hold the handle 1 and rotate it in the opposite direction of the rotation of the rotating mechanism. At this time, due to the meshing of the ratchet teeth and gear teeth, the tool body rotates relative to the rotating mechanism. After the handle 1 has rotated a certain angle, stop rotating the handle 1 and turn it back in the opposite direction. Because the reversing mechanism limits the ratchet teeth, the rotating mechanism and the tool body cannot rotate relative to each other. At this time, the tool body will drive the rotating mechanism to rotate synchronously, thereby driving the blade 10 to rotate, thus enabling the blade 10 to cut through the cylindrical battery casing. By repeatedly rotating and turning the handle 1, the blade 10 can rotate 360°, thereby disassembling and breaking the casing of the cylindrical battery.

[0023] It should be noted that this utility model does not specifically limit the specific structure of the reversing mechanism. Those skilled in the art can use the pawl and its driving structure that can form a ratchet mechanism with the ratchet teeth in the prior art.

[0024] In some embodiments, the rotating mechanism includes a rotating wheel 6, the top of which is provided with a ratchet disk 7, which meshes with the gear teeth of the tooling body.

[0025] In some embodiments, the rotating wheel 6 is provided with an annular flange 15, and a battery receiving through hole is formed in the middle of the annular flange 15. At least one of the upper and lower sides of the annular flange 15 is provided with a plurality of rollers or sliding bearings 13. Specifically, the plurality of rollers or sliding bearings 13 are distributed circumferentially at intervals. When the rotating wheel 6 rotates relative to the cylindrical battery, the arrangement of the rollers or sliding bearings 13 can reduce the friction between the rotating wheel 6 and the cylindrical battery, facilitating disassembly and shell breaking by tooling.

[0026] In some embodiments, the bottom of the rotating wheel 6 is provided with a retaining ring 8.

[0027] In some embodiments, the tool assembly includes a tool holder 9, which has a first tool receiving groove, and a second tool receiving groove on the rotating mechanism. Further, the second tool receiving groove is located on the rotating wheel 6. The first and second tool receiving grooves together form a tool moving groove, in which a cutting tool holder 11 is provided. A blade 10 is fixed to the cutting tool holder 11. An adjusting bolt 12 is also provided on the tool holder 9. One end of the adjusting bolt 12 is located outside the tool holder 9, and the other end extends into the tool moving groove and contacts the cutting tool holder 11. A spring mounting groove is provided in the cutting tool holder 11, and a spring is provided within the spring mounting groove. One end of the spring contacts the cutting tool holder 11, and the other end contacts the rotating mechanism. Further, the other end of the spring contacts the rotating wheel 6. When the adjusting bolt 12 is rotated to move towards the battery receiving through-hole, the adjusting bolt 12 presses against the cutting tool holder 11. The pressure on the cutting tool holder 11 compresses the spring and drives the blade 10 to move towards the battery receiving through-hole. When the adjusting bolt 12 moves away from the battery receiving through hole, the pressure on the cutting blade holder 11 decreases, the spring returns to its original position, and the cutting blade holder 11 drives the blade 10 to move away from the battery receiving through hole. The length of the blade 10 extending into the battery receiving through hole can be adjusted by adjusting the adjusting bolt 12, thereby adjusting the cutting depth.

[0028] In some embodiments, the tool holder 9 is further provided with a guide post 16, one end of which is connected to the tool holder 9 and the other end of which extends into the cutting tool holder 11.

[0029] In some embodiments, the guide post 16 extends into the spring mounting slot, and the spring is fitted onto the outside of the guide post 16.

[0030] In some embodiments, the reversing mechanism includes a protrusion 14, and a first limiting rod 17 and a second limiting rod 18 respectively disposed on both sides of the protrusion 14. One end of the first limiting rod 17 and the second limiting rod 18 are rotatably connected to the tooling body, and the middle part is connected to the tooling body by a spring. Specifically, the ends of the first limiting rod 17 and the second limiting rod 18 away from the rotating mechanism are rotatably connected to the tooling body. The protrusion 14 is also connected to a handle 5 disposed on the outside of the tooling body. The handle 5 is used to adjust the direction of the protrusion 14. By adjusting the direction, the protrusion 14 adjusts the contact between the first limiting rod 17 or the second limiting rod 18 and the ratchet teeth. Specifically, as shown... Figure 6 As shown, when the handle 5 drives the protrusion 14 to rotate to the right, the protrusion 14 presses against the second limiting rod 18, thereby compressing the spring. The second limiting rod 18 moves away from the ratchet teeth, and at this time only the first limiting rod 17 is in contact with the ratchet teeth, so the ratchet teeth can only rotate clockwise. Conversely, when the protrusion 14 rotates to the left, the protrusion 14 presses against the first limiting rod 17, thereby compressing the spring. The first limiting rod 17 moves away from the ratchet teeth, and at this time only the second limiting rod 18 is in contact with the ratchet teeth, so the ratchet teeth can only rotate counterclockwise.

[0031] In some embodiments, a cover plate 4 is also provided above the through hole of the upper fixing plate 2.
