Description

Technical Field

[0001] This application relates to the field of lithium battery processing, and in particular to a punching machine for soft-pack lithium batteries. Background Technology

[0002] With the rapid development of the new energy field, the demand for lithium batteries is increasing year by year. In the production process of lithium batteries, the manufacturing of the battery casing is a crucial link. Typically, lithium battery casings are made of soft-pack materials, and the manufacturing process is mainly completed through stamping dies.

[0003] In the traditional battery casing stamping process, upper and lower dies are typically used to stamp and shape the raw materials. First, the upper and lower dies press the raw materials to form the basic shape of the battery casing. However, in the current production method, manual operation is still required to load and unload the raw materials. Operators need to manually place the raw materials onto the lower die and manually remove the finished battery casing from the lower die after stamping. This not only increases the intensity of manual labor but also reduces production efficiency. Moreover, after the battery casing is stamped, it often requires a long time to cool naturally due to the high temperature generated during processing. Natural cooling is slow, which leads to a longer production cycle and thus affects the overall processing efficiency. Utility Model Content

[0004] This application provides a soft-pack lithium battery casing punching machine that eliminates the need for manual loading and unloading during use, thereby improving the processing efficiency of the battery casing. After the casing punching is completed, it accelerates heat dissipation, further enhancing the processing efficiency of the battery casing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a soft-pack lithium battery casing punching machine, the machine comprising:

[0006] Base;

[0007] A support plate is fixedly installed on one side of the base, and threaded rods are provided on both sides of the inner wall of the support plate through bearings;

[0008] A sleeve is threaded onto the outer surface of the threaded rod, and a connecting plate is fixedly provided on the outer surface of the sleeve;

[0009] A round rod is fixedly installed on both sides of the inner wall of the support plate, and a sliding cylinder is movably sleeved on the outer surface of the round rod.

[0010] As a further improvement of this application: one side of the connecting plate is fixedly disposed on the outer surface of the slide cylinder, a hydraulic rod is installed on one side of the connecting plate, a T-shaped plate is fixedly disposed at the output end of the hydraulic rod, two suction cups are installed on one side of the T-shaped plate, and an air pump is installed on one side of the T-shaped plate.

[0012] As a further improvement of this application: a cylinder is installed on one side of the mounting plate, an upper mold is installed at the output end of the cylinder, a lower mold is installed on one side of the base, and a shelf is fixedly provided on one side of the base.

[0013] As a further improvement of this application: a bidirectional motor is installed on one side of the support plate, and the output shaft of the bidirectional motor is fixedly disposed on one side of the threaded rod.

[0014] As a further improvement of this application: a cooling box is fixedly installed on one side of the base, and a partition is fixedly embedded in the inner wall of the cooling box.

[0016] As a further improvement of this application: fan blades are installed on one side of both the first rotating rod and the second rotating rod, pulleys are fixedly sleeved on the outer surfaces of both the first rotating rod and the second rotating rod, the two pulleys are connected by a belt, and multiple ventilation slots are opened on one side of the cooling box.

[0017] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0018] In this application, during the stamping of lithium battery casings, the raw material is placed on the upper side of the placement plate, the external power switch of the bidirectional motor is turned on, and the direction of rotation of the bidirectional motor output shaft is controlled, causing the sleeve to move the connecting plate, which in turn causes two suction cups to pick up the raw material. The output end of the cylinder is controlled to drive the upper mold to press downwards, stamping the raw material into a battery casing. After stamping, the casing on the lower mold is picked up by the two suction cups. After the casing stamping is completed, the output shaft of the bidirectional motor is controlled to rotate, causing the two suction cups to move to the top of the cooling box, causing the battery casing to fall into the cooling box. At this time, the drive motor switch is turned on, causing two fan blades to rotate. When the two fan blades rotate, they drive the air to circulate through multiple ventilation slots. The air is blown onto the casing through the slots on the partition plate, cooling the casing. Thus, during use, manual loading and unloading is not required, improving the processing efficiency of the battery casing. After the casing stamping is completed, the heat dissipation of the casing is accelerated, further improving the processing efficiency of the battery casing. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figure 1 , Figure 2 and Figure 3As shown, this application provides a soft-pack lithium battery casing punching machine, which includes a base 1; a support plate 2, fixedly disposed on one side of the base 1, and threaded rods 201 are provided on both sides of the inner wall of the support plate 2 via bearings; a sleeve 202, threadedly sleeved on the outer surface of the threaded rods 201, and a connecting plate 205 is fixedly disposed on the outer surface of the sleeve 202; a round rod 203, fixedly disposed on both sides of the inner wall of the support plate 2, and a slide cylinder 204 is movably sleeved on the outer surface of the round rod 203; one side of the connecting plate 205 is fixedly disposed on the outer surface of the slide cylinder 204; and a hydraulic rod 206 is installed on one side of the connecting plate 205. A T-shaped plate 207 is fixedly installed at the output end of the support plate 2. Two suction cups 209 are installed on one side of the T-shaped plate 207. An air pump 208 is installed on one side of the T-shaped plate 207. The air pump 208 is connected to the two suction cups 209 through an air pipe. An mounting plate 212 is fixedly installed on one side of the support plate 2. A cylinder 213 is installed on one side of the mounting plate 212. An upper mold 214 is installed at the output end of the cylinder 213. A lower mold 211 is installed on one side of the base 1. A shelf 215 is fixedly installed on one side of the base 1. A bidirectional motor 210 is installed on one side of the support plate 2. The output shaft of the bidirectional motor 210 is fixedly installed on one side of the threaded rod 201.

[0027] By adopting the above technical solution, the raw materials are placed on the upper side of the placement plate 215. At this time, the external power switch of the bidirectional motor 210 is turned on, and the output shaft of the bidirectional motor 210 can rotate in both directions. In turn, the output shaft of the bidirectional motor 210 drives the threaded rod 201 to rotate. Since the slide cylinder 204 can slide on the outer surface of the round rod 203, the slide cylinder 204 is connected to the sleeve 202 through the connecting plate 205. Thus, when the threaded rod 201 rotates in different directions, the sleeve 202 rotates in different directions on the outer surface of the threaded rod 201. By controlling the direction of rotation of the output shaft of the bidirectional motor 210, the sleeve 202 drives the connecting plate 205 to move. The two suction cups 209 are positioned above the raw materials. By controlling the hydraulic rod 206... The output end moves downward, further causing the output end of the hydraulic rod 206 to move, so that one side of the two suction cups 209 is pressed tightly against the outer surface of the raw material. At this time, the switch of the air pump 208 is controlled, and the two suction cups 209 are sucked up by the air pipe. Then, the output shaft of the bidirectional motor 210 is controlled to rotate, so that the connecting plate 205 moves above the lower mold 211. Then, the output end of the hydraulic rod 206 is controlled to move the two suction cups 209, and the T-shaped plate 207 is closed so that the raw material is on the lower mold 211. At this time, the output end of the cylinder 213 is controlled to drive the upper mold 214 to press downward, and the raw material is pressed into a battery shell. After the pressing is completed, the shell on the lower mold 211 is sucked up by the two suction cups 209.

[0028] Example 2, as Figure 1 and Figure 4As shown, a cooling box 3 is fixedly installed on one side of the base 1. A partition 301 is fixedly embedded in the inner wall of the cooling box 3. A drive motor 302 is installed on the inner wall of the base 1. A first rotating rod 303 is fixedly installed on the output shaft of the drive motor 302. A second rotating rod 304 is installed on one side of the inner wall of the cooling box 3 through a bearing. Fan blades 305 are installed on one side of both the first rotating rod 303 and the second rotating rod 304. Pulleys 306 are fixedly sleeved on the outer surfaces of both the first rotating rod 303 and the second rotating rod 304. The two pulleys 306 are connected by a belt 307. Multiple ventilation slots 308 are opened on one side of the cooling box 3.

[0029] By adopting the above technical solution, the output shaft of the bidirectional motor 210 is controlled to rotate, which drives the two suction cups 209 to move above the cooling box 3, causing the battery casing to fall into the cooling box 3. At this time, the drive motor 302 switch is turned on, and the output shaft of the drive motor 302 drives the first rotating rod 303 to rotate. Furthermore, one of the pulleys 306 drives the other pulley 306 to rotate under the action of the belt 307. Furthermore, the second rotating rod 304 and the first rotating rod 303 rotate in the same direction, although not at the same time, driving the two fan blades 305 to rotate. When the two fan blades 305 rotate, they drive the air to circulate through multiple ventilation slots 308. The air is blown onto the casing through the slots on the partition 301 to cool the casing.

[0030] Working principle: When stamping the lithium battery casing, the raw material is placed on the upper side of the placement plate 215. At this time, the external power switch of the bidirectional motor 210 is turned on, and the output shaft of the bidirectional motor 210 can rotate in both directions. This causes the output shaft of the bidirectional motor 210 to drive the threaded rod 201 to rotate. Since the slide cylinder 204 can slide on the outer surface of the round rod 203, and the slide cylinder 204 is connected to the sleeve 202 via the connecting plate 205, the sleeve 202 rotates in different directions on the outer surface of the threaded rod 201 when the threaded rod 201 rotates in different directions. By controlling the direction of rotation of the output shaft of the bidirectional motor 210, the... The sleeve 202 moves the connecting plate 205, positioning the two suction cups 209 above the raw material. By controlling the output end of the hydraulic rod 206 to move downwards, the output end of the hydraulic rod 206 moves the hydraulic rod 206, causing one side of the two suction cups 209 to press tightly against the outer surface of the raw material. At this point, the air pump 208 is switched on, causing the two suction cups 209 to pick up the raw material through the air pipe. Then, the output shaft of the bidirectional motor 210 is rotated, moving the connecting plate 205 above the lower mold 211. Finally, the output end of the hydraulic rod 206 moves the two suction cups 209, closing the T-shaped plate 20. 7. The raw material is positioned on the lower mold 211. At this time, the output end of the control cylinder 213 drives the upper mold 214 to press downwards, stamping the raw material into a battery casing. After stamping, the casing on the lower mold 211 is lifted by two suction cups 209. This eliminates the need for manual loading and unloading during use, improving the processing efficiency of the battery casing. After the casing stamping is completed, the output shaft of the bidirectional motor 210 is rotated, driving the two suction cups 209 to move above the cooling box 3, causing the battery casing to fall into the cooling box 3. At this time, the drive motor 302 switch is turned on, thereby driving... The output shaft of motor 302 drives the first rotating rod 303 to rotate, which in turn drives the other rotating rod 306 to rotate via one of the pulleys 306 and the belt 307. The second rotating rod 304 rotates in the same direction as the first rotating rod 303, although not simultaneously, thus driving the two fan blades 305 to rotate. When the two fan blades 305 rotate, they drive the air to circulate through multiple ventilation slots 308. The air is blown onto the outer casing through the slots on the partition 301, cooling the outer casing. This accelerates the heat dissipation of the outer casing after the stamping process is completed, further improving the processing efficiency of the battery casing.
