Description

Technical Field

[0001] This utility model relates to the field of lithium battery double sealing machine technology, and in particular to a labor-saving operating device for a manual vacuum double sealing machine. Background Technology

[0002] Soft-pack lithium batteries are made by wrapping a liquid lithium-ion battery with an aluminum-plastic film shell. In the event of a safety hazard, a soft-pack battery will at most bulge and crack. Compared with traditional steel-cased and aluminum-cased cells, they have advantages such as better safety performance, lighter weight, and larger capacity. The soft-pack lithium battery double-sealing machine is a device used to reseal soft-pack lithium batteries that have already been sealed once. Its purpose is to seal the top and bottom of the lithium battery to ensure the safety and performance of the battery.

[0003] For example, Chinese patent CN215745797U discloses a side cutting mechanism for a soft-pack lithium battery secondary sealing machine, including a base, a fixed plate, a positioning block, a lower cutting blade, a vertical plate, a top plate, a cylinder, a moving plate, a pressure plate, an upper cutting blade, a receiving funnel, a sensor mounting bracket, and a sensor. A fixed plate is installed above the base, and a positioning block is installed above the fixed plate. The positioning block has a U-shaped positioning protrusion. The soft-pack lithium battery cell is placed into the positioning groove, and the U-shaped positioning protrusion is aligned with the soft-pack... The three-sided contact of the lithium battery cell achieves precise positioning, ensuring the accuracy of the cutting position. The sensor detects that the soft-pack lithium battery cell has entered the positioning groove, the cylinder drives the moving plate to move down, the moving plate drives the pressure plate and the upper cutting plate to move down, the pressure plate presses the soft-pack lithium battery cell in the positioning groove, and the upper and lower cutting blades work together to cut off the aluminum film waste on the side of the soft-pack lithium battery cell. The waste falls into the receiving funnel in front for collection. The automated operation is highly efficient, and the precise cutting position ensures product quality and meets production requirements.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The above technical solution is not convenient for pressing and fixing the lithium battery to be packaged, thus reducing the convenience of lithium battery packaging. Utility Model Content

[0006] The purpose of this invention is to provide a labor-saving operating device for a manual vacuum double-sealing machine. First, the lithium battery to be packaged is placed on the placement platform. Then, the drive plate is turned by the threaded column, which causes the pressure block at the bottom of the drive plate to press against the pressing frame. This causes the heat sealing seat at the bottom of the pressing frame to move down. As the heat sealing seat moves down, the lithium battery is first pressed and fixed by the pressure pad at the bottom of the pressing plate. Then, the two ends of the lithium battery are heat-sealed by the heat sealing plate. There is no need to fix the lithium battery separately, which improves the convenience of lithium battery packaging. At the same time, by rotating the threaded column, the length of the threaded column can be adjusted, which saves the pressure on the drive plate, making lithium battery packaging more convenient.

[0035] Please refer to Figures 1 to 5 As shown, a vacuum pump 201 for evacuating the inside of the sealing cover 2 is installed on the side of the sealing cover 2.

[0036] Please refer to Figures 1 to 5As shown, the heat sealing mechanism 3 includes a pressing frame 301 slidably connected to the sealing cover 2. A return spring 302 is fixedly connected to the inner wall of the pressing frame 301, and the other end of the return spring 302 is fixedly connected to the top of the sealing cover 2. A heat sealing seat 303 is fixedly connected to the bottom of the pressing frame 301. Heat sealing plates 304 for heat sealing lithium batteries are installed on both sides of the bottom of the heat sealing seat 303. A pressing and fixing assembly 305 for pressing and fixing the lithium battery to be processed is installed at the center of the bottom of the heat sealing seat 303.

[0037] Please refer to Figures 1 to 5 As shown, the clamping and fixing assembly 305 includes a fixing seat 3051 fixedly connected to the heat sealing seat 303. A connecting spring 3052 is fixedly connected to the bottom of the fixing seat 3051. A clamping plate 3053 is fixedly connected to the bottom of the connecting spring 3052. Positioning slide rods 3054 are fixedly connected to both sides of the top of the clamping plate 3053. The top of the positioning slide rods 3054 is slidably connected to the fixing seat 3051. The tops of the two positioning slide rods 3054 are fixedly connected by a connecting rod 3055.

[0038] Please refer to Figures 1 to 5 As shown, the pressing mechanism 5 includes a mounting base 501 fixedly connected to one side of the top of the sealing cover 2. A connecting rotating block 502 is rotatably mounted on the mounting base 501 via a connecting shaft. A driving rotating plate 503 is fixedly connected to the connecting rotating block 502. A pressure block 504 is fixedly connected to the bottom of the driving rotating plate 503 at a position corresponding to the pressing frame 301.

[0039] Please refer to Figures 1 to 5 As shown, the side of the drive plate 503 is threadedly connected to a threaded post 5041 for turning the drive plate 503.

[0040] By adopting the above technical solution, the length of the threaded post 5041 can be adjusted by rotating the threaded post 5041, thereby saving the pressure required to press the drive plate 503, making the packaging of lithium batteries more convenient.

[0041] Please refer to Figures 1 to 5 As shown, a sealing sleeve 3011 is provided on the top of the sealing cover 2 and at the position corresponding to the pressing bracket 301;

[0042] By adopting the above technical solution, the sealing performance of the pressing frame 301 sliding on the sealing cover 2 is increased by setting the sealing slide sleeve 3011.

[0043] Please refer to Figures 1 to 5 As shown, a pressure pad 30531 is fixedly connected to the bottom of the pressure plate 3053;

[0044] By adopting the above technical solution, the clamping pad 30531 not only increases the stability of clamping the lithium battery to be processed, but also avoids wear on the lithium battery during clamping, thereby improving the practicality of this utility model.

[0045] The working principle of this utility model is as follows: First, the lithium battery to be packaged is placed on the placement platform 4. Then, the drive rotating plate 503 is turned by the threaded column 5041, which causes the pressure block 504 at the bottom of the drive rotating plate 503 to press against the pressing frame 301. This causes the heat sealing seat 303 at the bottom of the pressing frame 301 to move down. While the heat sealing seat 303 moves down, the lithium battery is first pressed and fixed by the pressure pad 30531 at the bottom of the pressing plate 3053. Then, the two ends of the lithium battery are heat-sealed by the heat sealing plate 304. There is no need to fix the lithium battery separately, which improves the convenience of lithium battery packaging. At the same time, by rotating the threaded column 5041, the length of the threaded column 5041 can be adjusted, which saves the pressing force on the drive rotating plate 503, making lithium battery packaging more convenient.

[0046] The workflow is as follows:

[0047] Preparation phase:

[0048] Place the lithium battery to be packaged on the placement platform 4 on top of the base 1, ensuring that the lithium battery is in the correct position.

[0049] Start the vacuum pump:

[0050] The vacuum pump 201 on the side of the sealing cover 2 is started to evacuate the inside of the sealing cover 2, providing a vacuum environment for the encapsulation of the lithium battery.

[0051] Adjust the pressing mechanism:

[0052] By rotating the threaded column 5041 and adjusting its length, the initial position of the drive plate 503 can be changed, thereby presetting the pressing force on the pressing frame 301 and reducing the force required during subsequent operations.

[0053] Start packaging:

[0054] By moving the drive plate 503, the drive plate 503 is driven to rotate around the mounting base 501 through the action of the connecting block 502 and the connecting shaft.

[0055] The pressure block 504 at the bottom of the drive plate 503 moves accordingly, pressing the pressing frame 301.

[0056] Pressing and tightening:

[0057] The pressing bracket 301 slides downward under the action of the pressing block 504, while the return spring 302 is compressed.

[0058] The heat-sealing seat 303 at the bottom of the pressing frame 301 moves downwards, first pressing and fixing the lithium battery by the pressing plate 3053 and the pressing pad 30531. The positioning slide bar 3054 and the connecting rod 3055 ensure the stable movement of the pressing plate 3053.

[0059] Heat sealing process:

[0060] After the lithium battery is stably compressed, the heat seal holder 303 continues to move downward, so that the heat seal plate 304 contacts both ends of the lithium battery.

[0061] The heat-sealing plate 304 heat-seales both ends of the lithium battery to complete the encapsulation of the lithium battery.

[0062] Reset and Retrieval:

[0063] After the encapsulation is completed, release the lever on the drive plate 503, and the pressing bracket 301 will automatically reset under the elastic force of the reset spring 302.

[0064] Open the sealing cover 2 (if necessary) and remove the encapsulated lithium battery from the placement platform 4.

[0065] End operation:

[0066] Turn off vacuum pump 201 to end the entire encapsulation process.

[0067] Through the above workflow, the manual vacuum double-sealing machine labor-saving operating device provided in this embodiment can conveniently complete the vacuum sealing of lithium batteries, while reducing the force required during operation and improving work efficiency and sealing quality.
