Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to a single-drive high-pressure vacuum packaging mechanism. Background Technology

[0002] During the battery encapsulation process, the battery encapsulation mechanism creates a vacuum inside the cavity after closing it, while simultaneously applying immense pressure to the battery pack. This combined action creates a high-vacuum environment inside the battery, resulting in high-quality batteries. Traditional battery encapsulation involves pressing the battery pack (or simply battery) together. This method lacks a vacuum environment, leading to suboptimal encapsulation results. Later, some vacuum encapsulation structures emerged that require two power units: one for cavity closing and the other for pressing the battery. This separate power unit handles both vacuum cavity closing and pressing, resulting in complex equipment structures, low encapsulation efficiency, and increased production costs. Summary of the Invention

[0034] Reference Figure 4 , Figures 6 to 9 As shown, the movable pressure plate assembly 3 includes a lower sealing lifting assembly 31, several third linear guide rods 32, a lower sealing head base 33, a lower pressure plate 34, and a lower sealing head 35.

Several third linear guide rods 32 are longitudinally installed on the movable plate 24, and the tops of several third linear guide rods 32 are connected and installed to the lower sealing head base 33. The lower sealing head base 35 is connected to the lower sealing head base 35. Several third linear guide rods 32 move up and down on the movable plate 24. The movable plate 24 slides on the several third linear guide rods 32. After the lower cavity 25 is sealed and joined with the upper cavity 40, the lower end cap base 33 can continue to drive the lower pressure plate 34 and the lower end cap 35 to rise for battery cell encapsulation. The movable plate 24 is connected and installed to the guide rod frame 22 through the lower end cap lifting assembly 31. The lower pressure plate 34 is installed on the top of the lower end cap base 33 and is used to support the battery 9. The lower end cap 35 is installed on the top of the lower end cap base 33 and is used to cooperate with the upper end cap 49 to encapsulate the battery 9. The lower pressure plate 34 and the lower end cap 35 are arranged side by side.

[0035] Reference Figure 9As shown, the lower sealing lifting assembly 31 includes a top rod 311, a bushing 312, an oil seal 313, an oil seal cover plate 314, and a pressure sensor 315. The top rod 311 passes through the top rod movable hole 27. The oil seal 313 and the bushing 312 are installed from top to bottom in the top rod movable hole 27 of the movable plate 24 and are respectively sleeved on the top rod 311. The upper end of the top rod 311 is connected and installed to the bottom of the lower sealing head base 33. The pressure sensor 315 is installed on the guide rod connecting top plate 221, and the lower end of the top rod 311 is connected and installed to the pressure sensor 315.

[0036] By adopting the above technical solution, when the lower pressure plate 34 rises and combines with the upper pressure plate 491 and presses against the upper pressure plate 491, the pressure sensor 315 detects that the pressure on the top rod 311 has reached the set data. Then, the cavity sealing drive assembly 21 stops driving the movable pressure plate assembly 3 to rise. This realizes fully automated control of the movable pressure plate assembly 3 to rise and cooperate with the upper pressure plate 491 to seal the battery cell. It has the advantages of high sealing efficiency, good sealing effect and high sealing accuracy.

[0037] Reference Figure 2 , Figure 6 and Figure 9 As shown, the cavity sealing drive assembly 21 includes a ball screw 211, a reducer 212, a lower cavity lifting drive device 213, a bearing seat 214, and a bearing 215. The reducer 212 is installed at the bottom of the guide rod frame 22, and the lower cavity lifting drive device 213 is installed at the bottom of the reducer 212. The ball screw 211 is connected to the fixed base plate 5. The lower cavity lifting drive device 213 is connected to the lower end of the ball screw 211 through the reducer 212.

The bearing 215 is installed inside the bearing seat 214. The upper end of the ball screw 211 is rotatably connected to the bearing seat 214 through the bearing 215.

[0038] When the above technical solution is adopted, the lower cavity lifting drive device 213 drives the guide rod frame 22 to rise above the fixed base plate 5 via the ball screw 211. The guide rod frame 22 drives the movable pressure plate assembly 3 to rise via the lower sealing lifting assembly 31, and simultaneously drives the movable plate 24 and the lower cavity 25 to rise via several springs 23. When the raised lower cavity 25 closes with the upper cavity 40, it is pressed by the upper cavity 40. The lower cavity 25 applies pressure to the movable plate 24, and the guide rod connecting the top plate 221 continues to rise. Several springs 23 buffer the movable plate 24, and the movable pressure plate assembly... As part 3 continues to rise, the lower end cap 35 and the upper end cap 49 press against each other to encapsulate the battery cell. When the pressure sensor 315 of the lower end cap lifting assembly 31 detects that the pressure on the top rod 311 has reached the set value, the cavity sealing drive assembly 21 stops driving the movable pressure plate assembly 3 to rise. This achieves fully automatic drive of the lower cavity 25 to rise and close with the upper cavity 40, and intelligently controls the lower pressure plate 34 to press the battery cell onto the upper pressure plate 491 and controls the lower end cap 35 and the upper end cap 49 to press together to encapsulate the battery cell. It has the advantages of high sealing efficiency and good sealing effect.

[0039] In this embodiment, the lower cavity lifting drive device 213 is configured as a servo motor.

[0040] Reference Figures 1 to 9 As shown, when this single-drive high-pressure vacuum packaging mechanism is working, the lower pressure plate 34 in the movable pressure plate assembly 3 is used to support the battery 9. The lower cavity lifting drive device 213 drives the lower cavity 40 and the movable pressure plate assembly 3 to rise, so that the lower cavity 25 rises to close with the upper cavity 40, the lower pressure plate 34 rises to press against the upper pressure plate 49, and the lower end cap 35 rises to press against the upper end cap 49 for sealing. Its overall structural design realizes the control of the lower cavity 25 and the upper cavity 40 to close with only one lower cavity lifting drive device 213. Since the lower cavity 25 or the upper cavity 40 is externally connected to a vacuum system, a vacuum can be evacuated after the lower cavity 25 and the upper cavity 40 are closed. The lower pressure plate 34 presses the battery cell against the upper pressure plate 491. During the process, air is vented, and the lower end cap 35 and upper end cap 49 are pressed together to encapsulate the battery cell. This achieves vacuum sealing of the lower cavity 25 and upper cavity 40 while simultaneously driving the lower pressure plate 34 to press the battery cell against the upper pressure plate 491 to vent air and driving the lower end cap 35 and upper end cap 49 to seal the battery cell. This gives it the advantages of simple equipment structure, high sealing efficiency, low production cost, and high operating efficiency. It not only solves the problem of unsatisfactory battery sealing effect caused by traditional sealing of the battery 9 in the absence of vacuum, but also solves the problem of complex equipment structure, low sealing efficiency, and high cost caused by the current vacuum sealing structure which requires two power devices to perform vacuum sealing and pressure sealing separately.
