Description

Technical Field

[0001] This utility model relates to the field of lithium battery packaging technology, specifically a lithium battery packaging machine. Background Technology

[0002] A lithium battery packaging machine is a specialized piece of equipment used in the lithium battery production process to heat-seal the cell casing. It is primarily used in the aluminum-plastic film packaging stage of soft-pack lithium batteries, achieving electrolyte sealing and external protection through thermal pressing and fusion. The lithium battery packaging machine uses a resistance heating element to transfer heat to the sealing head, utilizing the thermal conduction effect to heat the lithium battery packaging material. Under certain pressure, the packaging material softens and approaches a molten state, thus achieving pressure bonding and fusion.

[0003] Existing lithium battery packaging machines lack anti-scalding features. The distance between the battery holder and the hot-pressing head is too close, requiring users to manually place and retrieve the battery on the battery holder. Users' hands are prone to accidentally touching the hot-pressing head, which can easily lead to burns, resulting in poor safety. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a lithium battery packaging machine includes a base 1, a movable clamping mechanism 2 is provided on the top of the base 1, and a packaging mechanism 3 is provided on the right side of the base 1.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the movable clamping mechanism 2 includes a first stand 21 and a second stand 23. The first stand 21 is fixedly installed on the top of the base 1, and the second stand 23 is fixedly installed on the top of the base 1. A servo motor 22 is fixedly installed on the left side of the first stand 21. A crossbar 24 is fixedly installed between adjacent sides of the first stand 21 and the second stand 23. A lead screw 25 is rotatably connected between adjacent sides of the first stand 21 and the second stand 23. The output shaft of the servo motor 22 is fixedly connected to the end of the lead screw 25. A sliding seat 26 is slidably connected to the outer wall of the crossbar 24 and the lead screw 25. A clamping frame 27 is fixedly installed on the front side of the sliding seat 26. A support arm 28 is fixedly installed on the top of the clamping frame 27. After the lithium battery to be packaged is installed in the inner cavity of the clamping frame 27, the servo motor 22 is controlled to work, which drives the lead screw 25 to rotate and drives the sliding seat 26 to slide to the right on the outer wall of the crossbar 24. This moves the lithium battery on the clamping frame 27 to the packaging station. After the packaging is completed, the servo motor 22 is controlled again to drive the lithium battery to move to the left for reset, which makes it easy for the user to safely remove the lithium battery. This design avoids the problem of hands being easily burned during the process of disassembling and installing batteries on the machine, ensures the personal safety of workers, and improves the reliability of the structure.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cylinder 281 is fixedly installed on the inner wall of the support arm 28. A sealing slider 282 is slidably connected to the inner wall of the cylinder 281. An extension arm 283 is fixedly installed at the bottom of the sealing slider 282. The bottom of the extension arm 283 extends to the bottom of the cylinder 281 and is fixedly connected to a pressure member 285. An elastic member 284 is fixedly connected to the bottom of the sealing slider 282. The bottom of the elastic member 284 is fixedly connected to the bottom of the inner wall of the cylinder 281. A square [unclear] is fixedly connected to the top of the cylinder 281. A square tube 286 has an electric valve 287 fixedly connected to its side, and an electric valve 288 fixedly connected to the side of the square tube 286 away from the electric valve 287. A pressure gauge 289 is fixedly connected to the top of the square tube 286. An air source is pre-connected to the end of the electric valve 288. The electric valves 287, 288, and pressure gauge 289 are all electrically connected to an external controller. The pressure gauge 289 is used to monitor the air pressure inside the square tube 286 and record the air pressure reading. Feedback is sent to the controller. When installing the lithium battery on the clamping frame 27, the lithium battery to be packaged is first inserted into the inner cavity of the clamping frame 27 for movable positioning. Then, the electric valve 288 is opened, allowing air to be injected into the inner cavity of the cylinder 281 through the square tube 286. The gas pushes the sealing slider 282 downward in the inner cavity of the cylinder 281, while simultaneously causing the extension arm 283 to slide down, pushing the pressure member 285 downward. The downward-moving pressure member 285 can secure the lithium battery in the inner cavity of the clamping frame 27. Inside the cavity, pressure gauge 289 monitors changes in air pressure. When the preset value is reached, the controller automatically closes electric valve 288 to prevent excessive pressure from damaging the lithium battery. When the sealing slider 282 slides, it compresses the elastic element 284. If the battery needs to be removed, control electric valve 287 to open. Through the reset force of the elastic element 284, the sealing slider 282 and the pressure element 285 can be moved upward, thereby pulling the lithium battery out of the inner cavity of the clamping frame 27.

[0025] like Figure 5As shown, the encapsulation mechanism 3 includes a support frame 31, which is fixedly installed on the right side of the base 1. A stepper motor 32 is fixedly installed on the top of the support frame 31. A rotating column 33 is rotatably connected between the top and bottom of the inner wall of the support frame 31. The output shaft of the stepper motor 32 is fixedly connected to the top of the rotating column 33. A connecting arm 34 is fixedly installed on the outer wall of the rotating column 33. A strip seat 35 is fixedly installed at the end of the connecting arm 34 away from the rotating column 33. A cylinder 36 is fixedly installed on the outer wall of the strip seat 35. An electric heating head 37 is fixedly installed at the telescopic end of the cylinder 36. A sliding rod 38 is fixedly installed on the outer wall of the electric heating head 37. The sliding rod 38 is slidably connected to the inner wall of the strip seat 35. A mounting block 39 is detachably connected to the left side of the support frame 31. A heat insulation plate 391 is fixedly installed on the outer wall of the mounting block 39. An aluminum foil layer 392 is fixedly connected to the right side of the heat insulation plate 391. In the initial state, the heating head 37 is located on the right side of the support frame 31. After the lithium battery moves to the encapsulation position, the stepper motor 32 is controlled to rotate the rotating column 33 by 90 degrees, causing the heating head 37 to move to the back of the support frame 31. Then, the cylinder 36 is extended, which can drive the two heating heads 37 to move towards each other, realizing the function of encapsulating the lithium battery. After the encapsulation is completed, the cylinder 36 is reset, and the stepper motor 32 is controlled again to drive the heating head 37 to reset. The heat insulation plate 391 is made of rock wool, and through the cooperation of the heat insulation plate 391 and the aluminum foil layer 392, the heat radiation of the heating head 37 can be fully blocked. The workers are generally located on the front of the base 1 and the left side of the support frame 31. This design can avoid the problem of heat radiation from the heating head 37 being directly transferred to the workers, further protecting the workers' health.

[0026] This utility model provides a lithium battery packaging machine. The specific working principle is as follows: In use, the lithium battery to be packaged is first inserted into the inner cavity of the clamping frame 27 for positioning. Then, the electric valve 288 is opened, allowing air to pass through the square tube 286 and fill the inner cavity of the cylinder 281. The gas pushes the sealing slider 282 downwards within the cylinder 281, simultaneously pushing the pressure member 285 downwards. The downward-moving pressure member 285 secures the lithium battery within the clamping frame 27. Next, the servo motor 22 is controlled to rotate the lead screw 25, driving the sliding seat 26 to slide to the right on the outer wall of the crossbar 24. This moves the lithium battery on the clamping frame 27 to the packaging station. Finally, the stepper motor is controlled... Stepper 32 operates, causing the rotating column 33 to rotate 90 degrees, which causes the heating head 37 to move to the back of the support frame 31. Then, the control cylinder 36 extends, which can drive the two heating heads 37 to move towards each other, realizing the function of encapsulating the lithium battery. After encapsulation, the control cylinder 36 resets, and then the stepper motor 32 operates to drive the heating head 37 to reset. Then, the servo motor 22 operates again, driving the lithium battery to move to the left to reset. Then, the electric valve 287 can be opened, and the reset elastic force of the elastic element 284 drives the sealing slider 282 and the pressure element 285 to move upward, thereby pulling the lithium battery out of the inner cavity of the clamping frame 27, realizing the function of lithium battery encapsulation.
