Description

Technical Field

[0001] This utility model relates to the field of soft-pack battery packaging technology, and in particular to a lithium battery vacuum packaging machine. Background Technology

[0002] In the vacuum packaging process of pouch lithium batteries, puncturing the air bag and evacuating the mold cavity are key steps to ensure the quality of battery packaging. When the packaging process starts, the equipment must first accurately puncture the battery's air bag, and then use an air extraction device to evacuate the sealed mold cavity. The core purpose is to completely remove the gas inside the battery, laying the foundation for subsequent thermopressing packaging.

[0003] However, a common problem affecting efficiency in current processes is that the evacuation ports within the mold cavity are typically open and lack any flow guidance structure. This design allows gas to flow freely from various locations within the cavity to the evacuation ports when the vacuuming process begins. Because the air bag is often located at a certain distance from the evacuation port and lacks a directional flow channel, an "airflow stagnation zone" forms in the air bag area, where the gas velocity is significantly lower than in other areas of the cavity.

[0004] This difference in flow rate directly leads to significant negative impacts: residual gas inside the gas bag is difficult to remove quickly, necessitating an extended evacuation time to ensure thorough venting. This increased evacuation time directly prolongs the entire vacuum sealing cycle. In mass production, this accumulated time for a single process severely reduces the overall cycle time of the production line, hindering capacity increases and also increasing equipment energy consumption and production costs. Therefore, it is necessary to develop a lithium battery vacuum sealing machine to address these issues. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 6As shown, a lithium battery vacuum packaging machine includes a mounting platform 1, a first Y-axis drive assembly 2, a vacuuming mechanism 3, an upper packaging mechanism 4, and a lower packaging mechanism 5. The mounting platform 1 is provided with a clearance hole 11 and a strip hole 12, with the strip hole 12 corresponding to the front side of the clearance hole 11. The first Y-axis drive assembly 2 is fixed on the mounting platform 1. The vacuuming mechanism 3 includes a flow channel base plate 31, a flow channel cover plate 32, a battery carrier 33, and an air bag carrier 34. The flow channel base plate 31 is fixed to the power transmission line of the first Y-axis drive assembly 2. The outlet end is slidably connected to the mounting platform 1. The flow channel bottom plate 31 corresponds to the area above the clearance hole 11. A first sealing ring 311 is provided on the outer periphery of the upper end of the flow channel bottom plate 31. A transverse flow channel 312, a longitudinal flow channel 313, and an air extraction hole 314 are provided in the middle of the upper end of the flow channel bottom plate 31. The rear end of the longitudinal flow channel 313 is connected to the transverse flow channel 312. Two sets of longitudinal flow channels 313 are provided, corresponding to the left and right ends of the transverse flow channel 312. The air extraction hole 314 is provided on the front side of the longitudinal flow channel 313, corresponding to the strip hole 12. Above, the flow channel cover plate 32 is fixed above the flow channel bottom plate 31 and its bottom contacts the first sealing ring 311. The left and right sides of the flow channel cover plate 32 respectively cover the two sets of longitudinal flow channels 313. The upper outer periphery of the flow channel cover plate 32 is provided with a second sealing ring 321. The air bag carrier 34 is fixed to the middle rear side of the flow channel cover plate 32. The air bag carrier 34 is provided with an air passage hole 341 communicating with the transverse flow channel 312 along the X-axis direction. The air bag carrier 34 is also provided with multiple sets of cutting grooves 342. The rear end of the cutting groove 342 is connected to the air passage hole 312. The air vent 341 is connected. The battery platform 33 is fixed on the flow channel cover plate 32 and corresponds to the front side of the air bag platform 34. Two sets of battery platforms 33 are arranged side by side on the left and right. The vacuum mechanism 3 is provided with a heat sealing hole 35 that penetrates the flow channel bottom plate 31 and the flow channel cover plate 32 vertically. The heat sealing hole 35 corresponds to the space between the battery platform 33 and the air bag platform 34. The upper sealing mechanism 4 is mounted on the mounting platform 1 and corresponds to the upper part of the flow channel cover plate 32. The lower sealing mechanism 5 is fixed on the mounting platform 1 and corresponds to the lower part of the air vent 11.

[0023] In the initial state, the vacuuming mechanism 3, driven by the first Y-axis drive assembly 2, is located in front of the mounting platform 1. The robot arm places the battery from the previous process onto the battery carrier 33, and the battery's air bag is placed on the air bag carrier 34. Then, the first Y-axis drive assembly 2 drives the vacuuming mechanism 3 to move backward, so that the vacuuming mechanism 3 is located between the upper packaging mechanism 4 and the lower packaging mechanism 5. Then, both the upper packaging mechanism 4 and the lower packaging mechanism 5 close the mold to the vacuuming mechanism 3, so that the upper packaging mechanism 4, the lower packaging mechanism 5, and the vacuuming mechanism 3 form a closed packaging cavity. The air extraction hole 314 is connected to the air extraction device. During the packaging process, the vacuum is drawn through the air extraction hole 314 to evacuate the packaging cavity. The gas from the upper packaging mechanism 4 gathers from the air passage 341 and flows through the transverse flow channel 312 and the longitudinal flow channel 313 in sequence, and finally exits from the air extraction hole 314. The gas from the lower packaging mechanism 5 gathers in the air passage 341 after passing through the heat sealing hole 35, and finally exits from the air extraction hole 314. The advantage of this design is that it allows all the gas in the encapsulation cavity to converge through the vent 341 and then be discharged from the vent 314 through the transverse flow channel 312 and the longitudinal flow channel 313, which greatly increases the gas flow rate at the gas bag, quickly removes the gas from the gas bag, and improves production efficiency.

[0024] The battery platform 33 includes an adjustable platform 331, a blocking boss 332, a second Y-axis drive assembly 333, and an L-shaped plate 334. The adjustable platform 331 is fixed on the flow channel cover 32 and its position is adjustable in the front-rear direction. The blocking boss 332 is fixed to the rear end of the adjustable platform 331 and protrudes upward from the upper end surface of the adjustable platform 331. The second Y-axis drive assembly 333 is fixed on the flow channel cover 32. The vertical part of the L-shaped plate 334 is fixed to the power output end of the second Y-axis drive assembly 333, and the horizontal part of the L-shaped plate 334 is placed on the upper end surface of the adjustable platform 331.

[0025] The robotic arm places the battery from the previous process onto the horizontal part of the L-shaped plate 334, with the battery's air bag positioned above the blocking protrusion 332. The second Y-axis drive assembly 333 drives the L-shaped plate 334 to move backward until the rear end of the battery body contacts the side wall of the blocking protrusion 332 and stops. At this point, the battery is positioned and the battery air bag is aligned with the air bag carrier 34. Then, the first Y-axis drive assembly 2 drives the vacuum mechanism 3 to move backward.

[0026] The upper packaging mechanism 4 includes a mounting frame 41, a first Z-axis drive assembly 42, a lifting mounting plate 43, a second Z-axis drive assembly 44, a lifting connector 45, a packaging side frame 46, a lifting pressure plate assembly 47, a lifting heat sealing assembly 48, and a lifting bayonet assembly 49. The mounting frame 41 is mounted on the mounting platform 1. The first Z-axis drive assembly 42 is fixed to the upper end of the mounting frame 41. The lifting mounting plate 43 is fixed to the power output end of the first Z-axis drive assembly 42 and is slidably connected to the mounting frame 41. The second Z-axis drive assembly 44 is fixed to the left and right sides of the lifting mounting plate 43. The packaging side frame 46 corresponds between the lifting mounting plate 43 and the flow channel cover plate 32. The lifting connector 45... The two sets of lifting connectors 45 are fixed on the left and right sides of the encapsulation side frame 46 and are slidably connected to the mounting bracket 41. The two sets of lifting connectors 45 are respectively fixed to the power output ends of the two sets of second Z-axis drive components 44. The lower end face of the lifting mounting plate 43 is provided with a third sealing ring. The upper outer periphery of the encapsulation side frame 46 corresponds to the third sealing ring, and the lower outer periphery of the encapsulation side frame 46 corresponds to the second sealing ring 321. The lifting pressure plate assembly 47, the lifting heat sealing assembly 48, and the lifting bayonet assembly 49 are all fixed on the lifting mounting plate 43 and correspond to the inside of the encapsulation side frame 46. The lifting pressure plate assembly 47, the lifting heat sealing assembly 48, and the lifting bayonet assembly 49 correspond to the battery platform 33, the heat sealing hole 35, and the air bag platform 34 above, respectively.

[0027] After the first Y-axis drive assembly 2 drives the vacuum mechanism 3 to move backward, the lower packaging mechanism 5 closes the mold upward. At the same time, the first Z-axis drive assembly 42 drives the lifting mounting plate 43 to descend, thereby driving the packaging side frame 46 to descend and press against the second sealing ring 321. The lifting pressure plate assembly 47 descends and presses against the upper end face of the battery body to ensure the stability of the battery position. Then, the lifting piercing assembly 49 descends, the piercing inserts into the cutting groove 342 and pierces the battery gas bag, allowing the gas and excess electrolyte in the gas bag to be discharged, and a vacuum is drawn into the packaging cavity. After the gas in the gas bag is discharged, the lifting heat sealing assembly 48 descends, and the lifting heat sealing assembly 48 and the upper and lower heat sealing heads in the lower packaging mechanism 5 heat seal the battery gas bag. When it is necessary to inspect and replace the piercing, heat sealing head and other parts, with the upper packaging mechanism 4 open, the packaging side frame 46 is driven to descend by the second Z-axis drive assembly 44, exposing the piercing, heat sealing head and other parts for easy inspection and replacement.

[0028] The lifting pressure plate assembly 47 includes a first fixed frame 471, a second fixed frame 472, a first movable frame 473, a second movable frame 474, a pressure plate 475, a pressure sensor 476, a third Z-axis drive assembly 477, and a lifting movable block 478. The first fixed frame 471 is mounted above the lifting mounting plate 43, the second fixed frame 472 is mounted above the first fixed frame 471, the first movable frame 473 is vertically slidably mounted on the lifting mounting plate 43, the second movable frame 474 is vertically slidably mounted on the first fixed frame 471, the pressure plate 475 is fixed to the lower end of the first movable frame 473 and corresponds to the upper part of the battery platform 33, the upper and lower ends of the pressure sensor 476 are respectively fixed to the lower end of the second movable frame 474 and the upper end of the first movable frame 473, the third Z-axis drive assembly 477 is fixed to the upper end of the second fixed frame 472, and the lifting movable block 478 is fixed to the upper end of the second movable frame 474 and connected to the power output end of the third Z-axis drive assembly 477.

[0029] The third Z-axis drive assembly 477 drives the lifting movable block 478 to descend, thereby simultaneously driving the first movable frame 473 and the second movable frame 474 to descend, so that the pressure plate 475 presses against the upper end surface of the battery body. The pressure sensor 476 is used to detect the pressure of the pressure plate 475 on the battery to improve accuracy.

[0030] This design also includes a pressure relief assembly 6, which includes a third fixing frame 61, a pressure relief cylinder 62, and a pressure relief plug 63. A pressure relief hole 431 is provided on the lifting mounting plate 43. The third fixing frame 61 is fixed above the lifting mounting plate 43. The pressure relief cylinder 62 is fixed on the third fixing frame 61. The pressure relief plug 63 is fixed at the power output end of the pressure relief cylinder 62 and corresponds to the pressure relief hole 431 above it.

[0031] After the encapsulation is completed, the encapsulation cavity is still in a vacuum state. Directly opening the mold will cause obvious vibration of the equipment and have an adverse effect on the surrounding equipment. It is necessary to drive the pressure relief plug 63 to lift through the pressure relief cylinder 62, so that the pressure relief hole 431 is no longer blocked, allowing outside air to enter the encapsulation cavity through the pressure relief hole 431, breaking the vacuum state in the encapsulation cavity, so that the mold can be opened smoothly.

[0032] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
