[0010] According to the above technical solution, the second adsorption hole is connected to the inside of the first gas storage chamber, so that the first gas storage chamber controls the second adsorption hole to adsorb the outer wall of the battery casing seal. A heating block is fixedly connected to the inner wall of the clamping plate. The heating block is used to heat the clamping plate to seal the battery casing. A pressure sensor is provided on the inner wall of the clamping plate to monitor the clamping force of the clamping plate on the outer wall of the battery casing seal.

[0011] According to the above technical solution, a clamping mechanism is provided inside the working chamber. The clamping mechanism includes a slide table. The outer wall of the slide table is slidably connected to the bottom of the inner wall of the working chamber via a slide rail.

A vacuum source is provided inside the base and is connected to the interior of gas storage chamber one and gas storage chamber two via a connecting pipe. By setting up the clamping mechanism to clamp the battery and adjust the battery position, the battery seal is prevented from deviating from the connector, ensuring accurate docking and further enhancing the stability of the battery sealing of the soft-pack lithium battery production equipment.

[0012] According to the above technical solution, a motor is installed inside the working chamber to drive the slide table to slide on the inner wall of the working chamber. A cylinder is fixedly connected to the outer wall of the slide table. The output end of the cylinder is fixedly connected to the inner wall of the support plate.

A guide groove one is opened on the inner wall of the support plate, and the support rod is slidably connected to the groove wall of the guide groove one through a slider. The guide groove one is used to guide and limit the support rod, and the cylinder four is used to drive the support rod to slide in the guide groove one.

[0014] According to the above technical solution, a limiting groove is formed on the inner wall of the support plate, and an exhaust mechanism is provided inside the support plate. The exhaust mechanism includes a rotating rod one. The top of the limiting groove is slidably connected to the groove wall of the rotating rod one.

The outer wall of the exhaust wheel is on the same horizontal plane as the clamp. The exhaust wheel contacts the outer wall of the battery casing, squeezing and venting the battery casing, and making the battery casing flat. By setting an exhaust mechanism, the folds of the casing generated during the battery exhaust process are smoothed out, keeping the casing flat and increasing the safety of the battery. At the same time, the vibration generated by the exhaust mechanism guides and vents the air remaining in the dead corners of the battery, and works with the docking mechanism to quickly extract the air inside the battery, improving the exhaust efficiency of the soft-pack lithium battery production equipment.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Example 1, please refer to Figures 1-4 The present invention provides a technical solution: a lithium battery packaging device, including a base 100, a working chamber 101 connected to the top of the base 100, and a docking mechanism 200 provided inside the working chamber 101; During the secondary sealing process of pouch batteries, after the battery is filled with electrolyte, the opening of the battery casing is in a closed state, making it difficult for the sealing equipment to accurately align with the opening when vacuuming the inside of the battery casing. This affects the vacuum extraction effect inside the battery casing. Therefore, a docking mechanism 200 is set up to adsorb the battery casing opening, so that the battery casing opening is opened before docking. This avoids docking difficulties caused by the sealing opening being closed after the battery electrolyte is filled. At the same time, the docking mechanism 200 continuously vacuums the inside of the battery during the sealing process, so that the battery is sealed under negative pressure. This prevents residual air inside the partial sealing and increases the stability of the pouch lithium battery production equipment for battery sealing. The docking mechanism 200 includes a support platform 201. The top of the support platform 201 is fixedly connected to the top of the inner wall of the working chamber 101 via a support column. A second air storage chamber 207 is slidably connected to the inner wall of the support platform 201. A connecting joint 208 is fixedly connected to the bottom of the second air storage chamber 207. The connecting joint 208 is used to dock with the sealing part of the battery casing. An adsorption hole 209 is provided on the outer wall of the connecting joint 208 for extracting air from inside the battery casing. A sliding groove 203 is provided on the outer wall of the support platform 201. The groove wall of the sliding groove 203 is slidably connected via a slider. There is a gas storage chamber 204, and a clamping plate 205 is fixedly connected to the bottom of the gas storage chamber 204. The inner wall of the clamping plate 205 has an adsorption hole 211, which is used to adsorb the outer wall of the battery casing seal. A cylinder 202 is fixedly connected to the top of the support platform 201. The output end of the cylinder 202 is fixedly connected to the top of the connector 208. The adsorption hole 209 is connected to the inside of the gas storage chamber 207, so that the gas storage chamber 207 controls the adsorption hole 209 to extract air from the inside of the battery casing. The cylinder 202 is used to drive the connector 208 to descend. A cylinder 206 is fixedly connected to the top of the support platform 201, which aligns with the battery casing seal. The output end of the cylinder 206 is fixedly connected to the outer wall of the gas storage chamber 204. The cylinder 206 drives the gas storage chamber 204 to slide within the groove 203, adjusting the position of the clamping plate 205. The inner wall of the clamping plate 205 is inclined and parallel to the inclined surface of the outer wall of the connector 208, allowing the inner wall of the clamping plate 205 to adhere to the outer wall of the battery casing and seal against the outer wall of the connector 208. The inner wall of the clamping plate 205 is provided with an anti-slip surface to prevent the battery casing from slipping due to friction. The shell falls off, and the second adsorption hole 211 is connected to the inside of the first gas storage chamber 204, so that the first gas storage chamber 204 controls the second adsorption hole 211 to adsorb the outer wall of the battery shell seal. The inner wall of the clamping plate 205 is fixedly connected to the heating block 210, which is used to heat the clamping plate 205 to seal the battery shell. The inner wall of the clamping plate 205 is equipped with a pressure sensor to monitor the clamping force of the clamping plate 205 on the outer wall of the battery shell seal. The base 100 is equipped with a vacuum source and is connected to the inside of the first gas storage chamber 204 and the second gas storage chamber 207 through a connecting pipe. When the lithium battery packaging equipment is put into use, a sealed battery is placed in the working chamber 101. The motor-driven clamping mechanism 300 inside the working chamber 101 is activated to adjust its position, aligning the clamping mechanism 300 with the battery casing and clamping it. The motor-driven clamping mechanism 300 then adjusts the battery's position so that the sealed end of the battery casing is inside the clamping plate 205. Simultaneously, cylinder 206 is activated to drive the air storage chamber 204, bringing the clamping plate 205 into contact with the sealed end of the battery casing. At the same time, the air storage chamber 204 activates a vacuum source to extract air from the adsorption hole 211, causing the adsorption hole 211 to adsorb the sealed end of the battery casing, bringing the sealed end of the battery casing against the inclined inner wall of the clamping plate 205. Cylinder 202 is then activated to drive the connector 208 downwards, simultaneously causing the connector 208 to slide the adsorption hole 209 downwards along the inner wall of the support platform 201. The outer wall of the connector 208 is made to fit against the inner wall of the battery casing and contact the inner wall of the clamping plate 205, so that the sealing point of the battery casing is sealed by the connector 208 and the clamping plate 205. After the connector 208 and the sealing point of the battery casing are aligned, the adsorption hole 209 is connected to the vacuum source through the second air storage chamber 207, so that the adsorption hole 209 draws air from the inside of the battery. After the air inside the battery is discharged, the retracting cylinder 202 raises the connector 208. At the same time, the retracting cylinder 206 drives the first air storage chamber 204 to slide towards the connector 208, so that the first air storage chamber 204 drives the clamping plate 205 to fit against the outer wall of the clamping plate 205 and adjust synchronously with the connector 208. During the process of the adsorption hole 209 drawing air from the inside of the battery, the casing is sealed until the clamping plates 205 fit together and the battery casing is sealed. The heating block 210 is activated to heat the clamping plate 205, and the battery casing is completed in a second sealing process.

[0025] Example 2, based on Example 1, please refer to... Figures 5-7 The present invention provides a technical solution: a clamping mechanism 300 is provided inside the working chamber 101; During the secondary sealing process of pouch batteries, after the battery is filled with electrolyte, the opening in the battery casing is in a closed state, which makes it difficult for the sealing equipment to accurately align with the opening when vacuuming the inside of the battery casing, affecting the vacuum extraction effect inside the battery casing. Therefore, a clamping mechanism 300 is set to clamp the battery and adjust its position to prevent the battery seal from deviating from the connector 208, ensuring accurate alignment and further enhancing the stability of the battery sealing in the pouch lithium battery production equipment. The clamping mechanism 300 includes a slide table 301. The outer wall of the slide table 301 is slidably connected to the bottom of the inner wall of the working chamber 101 via a slide rail. A support plate 302 is slidably connected to the inner wall of the slide table 301 via a limit rod. A chuck 305 is fixedly connected to the outer wall of the support plate 302. The outer wall of the chuck 305 is used to clamp the battery casing. A pressure sensor is installed inside the chuck 305 to monitor the clamping force of the chuck 305 on the battery casing. A motor is installed inside the working chamber 101 to drive the slide table 301 to slide on the inner wall of the working chamber 101. A cylinder 303 is fixedly connected to the outer wall of the slide table 301. The output end of the cylinder 303 is fixedly connected to the inner wall of the support plate 302. The cylinder 303 is used to drive the support plate 302 to slide on the inner wall of the slide table 301, so that the chuck 305 clamps the battery casing. When secondary encapsulation is required after the battery electrolyte filling is completed, the battery is placed on the bottom plate inside the working chamber 101. The motor-driven slide 301 inside the working chamber 101 is activated and slides to the appropriate position of the battery at the bottom of the inner wall of the working chamber 101. The cylinder 303 is activated to drive the support plate 302 to slide towards the battery on the inner wall of the slide 301, so that the clamp 305 contacts the outer wall of the battery casing and clamps the battery. After the battery is clamped, the position is adjusted by the motor-driven slide 301 inside the working chamber 101 so that the battery is aligned with the bottom of the connector 208 and the battery casing seal is aligned with the outer wall of the connector 208. When the battery casing is clamped by the clamp 305 in contact with the outer wall of the battery casing, the pressure sensor inside the clamp 305 monitors the clamping force of the clamp 305 on the battery casing to prevent the clamp 305 from scratching the battery casing.

[0026] Example 3, based on Examples 1 and 2, please refer to... Figure 8 The present invention provides a technical solution: a cylinder 304 is fixedly connected to the outer wall of a support plate 302, and a support rod 308 is hinged to the output end of the cylinder 304 through a hinge block. A guide groove 306 is provided on the inner wall of the support plate 302. The support rod 308 is slidably connected to the groove wall of the guide groove 306 through a slider. The guide groove 306 is used to guide and limit the support rod 308. The cylinder 304 is used to drive the support rod 308 to slide in the guide groove 306. A limit groove 307 is provided on the inner wall of the support plate 302. An exhaust mechanism 400 is provided inside the support plate 302. During the secondary sealing process of pouch batteries, after the battery is filled with electrolyte, the opening in the battery casing is in a closed state. This makes it difficult for the sealing equipment to accurately align with the opening when vacuuming the inside of the battery casing, affecting the vacuum extraction effect inside the battery casing. At the same time, the air remaining in the dead corners inside the battery during the sealing process cannot be discharged from the battery casing, affecting the performance and safety of the battery after sealing. Therefore, an exhaust mechanism 400 is set up to smooth out the wrinkles in the casing produced during the primary sealing process, keeping the casing flat and increasing the safety of the battery. At the same time, the exhaust mechanism 400 guides and discharges the air remaining in the dead corners of the battery through vibration, and works with the docking mechanism 200 to quickly extract the air inside the battery, improving the exhaust efficiency of the pouch lithium battery production equipment. The exhaust mechanism 400 includes a rotating rod 401. The top of the limiting groove 307 is slidably connected to the groove wall of the rotating rod 401. The outer wall of the rotating rod 401 is hinged to the inner wall of the support rod 308. A gear on the top of the rotating rod 401 meshes with a rack on the inner wall of the limiting groove 307 to drive the rotating rod 401 to rotate. A rotating rod 402 is rotatably connected to the outer wall of the rotating rod 401 via a bearing. The bottom of the rotating rod 402 is slidably connected to the groove wall of the limiting groove 307. A gear on the bottom of the rotating rod 402 meshes with a rack on the inner wall of the limiting groove 307 to drive the rotating rod 402 to rotate in the opposite direction to the rotating rod 401. An exhaust wheel 403 is fixedly connected to the outer wall of the rotating rod 402. The outer wall of the exhaust wheel 403 is at the same horizontal plane as the clamp 305. The exhaust wheel 403 contacts the outer wall of the battery casing, squeezing and venting the battery casing and flattening it. A guide groove 404 is provided on the outer wall of the exhaust wheel 403. The guide groove 404 is spirally opened on the outer wall of the exhaust wheel 403 to guide the gas inside the battery casing. A guide hole 405 is provided on the outer wall of the rotating rod 402. An insert block 406 is slidably connected to the inner wall of the exhaust wheel 403. The outer wall of the insert block 406 is inserted into the groove wall of the guide hole 405. The guide hole 405 is used to guide the insert block 406. A spring 407 is fixedly connected to the outer wall of the insert block 406. The other end of the spring 407 is fixedly connected to the inner wall of the exhaust wheel 403. A slot is provided on the outer wall of the rotating rod 401 to insert the insert block 406. The rotating rod 401 and the rotating rod 402 rotate in opposite directions, so that the insert block 406 repeatedly inserts into the slot on the outer wall of the rotating rod 401 and generates vibration. The vibration is transmitted to the exhaust wheel 403 through the insert block 406, so that the exhaust wheel 403 exhausts the gas from the battery casing through vibration. After the connector 208 is aligned with the battery casing seal, and air is vented from the battery through the suction hole 209, the cylinder 304 is activated, causing the support rod 308 to slide along the inner wall of the guide groove 306. Simultaneously, the support rod 308 is limited by the rotating rod 401, causing it to swing and slide within the limiting groove 307. At the same time, the rotating rod 401 drives the rotating rod 402 to slide synchronously within the limiting groove 307. The rotating rod 401, through the teeth set at the top... The wheel meshes with the rack inside the limiting groove 307 and rotates within the limiting groove 307. Simultaneously, the second rotating rod 402 meshes with the rack inside the limiting groove 307 via a gear at its bottom, sliding in the opposite direction to the first rotating rod 401 within the limiting groove 307. At the same time, the exhaust wheel 403 is fixedly connected to the outer wall of the second rotating rod 402, causing the second rotating rod 402 to drive the exhaust wheel 403 to roll along the outer wall of the battery casing during rotation, compressing and venting the battery casing. This is achieved through a guide groove on the outer wall of the exhaust wheel 403. The second 404 guides the air inside the battery, allowing it to be quickly expelled from the battery casing. Simultaneously, as the exhaust wheel 403 rolls along the outer wall of the battery casing, it stretches the wrinkles created during the initial encapsulation, resulting in a smoother casing after secondary encapsulation. During the rolling of the exhaust wheel 403, the first rotating rod 401 rotates in the opposite direction inside the second rotating rod 402. The insert block 406, supported by a spring 407, is guided by a guide hole 405 and inserted into a slot on the outer wall of the first rotating rod 401, generating vibrations that are transmitted to the exhaust wheel 403 through the insert block 406. This vibrations allow the exhaust wheel 403 to expel air from the battery casing, preventing air trapped in dead zones. The exhaust wheel 403 is also limited by the second rotating rod 402 and, through gear engagement with a rack inside the limiting groove 307, rolls along the battery casing to expel air, preventing damage to the battery casing due to friction during the rolling process.
