[0020] To solve its technical problem, this utility model provides: Reference Figure 1 , Figure 2 , Figure 3A dual-station suction cup loading / unloading mechanism for soft-pack batteries includes a swing-arm multi-axis robot assembly 1.

Each lifting module 20 independently controls the lifting motion of one overpressure-resistant suction cup assembly 3. Each overpressure-resistant suction cup assembly 3 includes an overpressure-resistant module 31 and a suction cup module 32. In practical applications, the swing-arm multi-axis robot assembly 1 drives the dual lifting assembly 2 and the overpressure-resistant suction cup assembly 3 to a preset loading / unloading position, offering advantages such as fast operation and high loading / unloading efficiency. The dual lifting assembly 2 drives two sets of overpressure-resistant suction cup assemblies 3 to perform loading / unloading operations, further improving work efficiency. Furthermore, the overpressure-resistant module 31 in the overpressure-resistant suction cup assembly 3 prevents damage to the battery cells due to excessive pressure during loading / unloading, protecting the battery cells, improving product quality and yield, and enhancing the company's production efficiency.

[0021] Reference Figure 4 In some specific embodiments, the swing-arm multi-axis robot assembly 1 includes a robot mounting base 11 and a multi-axis robot 12 mounted on the robot mounting base 11. The multi-axis robot 12 includes a robot fixing module 121 fixed on the robot mounting base 11. A first rotating shaft 122 is provided on the robot fixing module 121. A first swing arm 123 is provided at the output end of the first rotating shaft 122. A second rotating shaft 124 is provided at the free end of the first swing arm 123. A second swing arm 125 is provided at the output end of the second rotating shaft 124. A rotatable and liftable rotary lifting shaft 126 is provided at the free end of the second swing arm 125. A connecting flange 127 is provided at the lower end of the rotary lifting shaft 126, and it is fixedly connected to the dual lifting assembly 2 through the connecting flange 127. This swing-arm multi-axis robot assembly 1, through the coordinated and synchronous movement of the first swing arm 123, the second swing arm 125, the first rotating shaft 122, the second rotating shaft 125, and the rotary lifting shaft 126, has a fast action cycle and greatly improves the loading and unloading efficiency.

[0022] Reference Figure 3 , Figure 5In some specific embodiments, the dual lifting assembly 2 includes a lifting assembly mounting plate 21 and two lifting modules 20 fixedly disposed on both sides of the lifting assembly mounting plate 21. Each lifting module 20 includes a lifting drive cylinder 201; in this embodiment, the lifting drive cylinder 201 is a three-axis cylinder. The anti-overpressure suction cup assembly 3 is fixedly disposed on the output shaft of the lifting drive cylinder 201. Specifically, in this embodiment, a connecting plate 23 is provided on the rear side of the lifting assembly mounting plate 21, and the lifting modules 20 are fixedly disposed at both ends of the connecting plate 23. Air distribution blocks 24 adapted to the suction cup modules 32 on the anti-overpressure suction cup assembly 3 are also provided on both sides of the lifting assembly mounting plate 21. A central through hole is provided in the middle of the lifting assembly mounting plate 21 for connecting with the connecting flange 127 on the swing-arm multi-axis robot assembly 1. The rotating lifting shaft 126 passes through this central through hole and is fixedly connected to the lifting assembly mounting plate 21 via the connecting flange 127.

[0023] Reference Figure 1 , Figure 3 , Figure 6 and Figure 7 In some specific embodiments, the overpressure protection module 31 includes a fixed base 311 fixedly mounted on the output end of the lifting module 20 and a sliding base 312 mounted on the fixed base 311 and slidable relative to the fixed base 311. A limit guide post 313 is provided between the fixed base 311 and the sliding base 312, and an overpressure protection spring is sleeved on the limit guide post 313. A linear guide rail 314 is provided between the fixed base 311 and the sliding base 312, and the relative sliding function between the sliding base 312 and the fixed base 311 is realized through the linear guide rail 314. In practical applications, when the swing-arm multi-axis robot assembly 1 drives the suction cup module 32 to press down beyond the preset stroke, the overpressure protection spring will be compressed. The stroke compression prevents the battery cell from being subjected to overpressure impact, thus protecting the battery cell.

[0024] Reference Figure 6 On the other hand, one of the fixed base 311 and the sliding base 312 is equipped with an overpressure sensor, and the other of the fixed base 311 and the sliding base 312 is equipped with an overpressure sensing plate 315 adapted to the overpressure sensor. When the compression of the overpressure spring exceeds the preset stroke, a signal is sent through the overpressure sensing plate 315 and the overpressure sensor. At this time, the control module of the mechanism will control the coordinated action of each component and drive the suction cup module 32 to retract, so as to avoid excessive pressure on the battery cell and protect the battery cell.

[0025] In this way, the battery cell is protected against overvoltage at both the physical and automatic control levels, preventing damage caused by overvoltage and improving product yield and processing quality.

[0026] In some specific embodiments, the overpressure-resistant suction cup assembly 3 further includes a suction cup mounting plate 33 fixedly mounted on the sliding base 312. The suction cup mounting plate 33 is provided with a plurality of elongated mounting slots 331, and the suction cup module 32 is fixedly mounted on the elongated mounting slots 331. The specific installation position of the suction cup module 32 can be adjusted through the elongated mounting slots 331, thereby adapting to different application occasions and improving application flexibility and versatility.

[0027] The operating procedure for this dual-station suction cup loading and unloading mechanism for pouch batteries is as follows: Step 1: The swing arm multi-axis robot assembly 1 moves above the magazine bin. After the magazine bin lifts the battery cell, the Z-axis of the swing arm multi-axis robot assembly 1 descends to the suction cup contacting the battery cell. Step 2: After the overvoltage suction cup assembly 3 picks up the battery cell, the swing arm multi-axis robot assembly 1 lifts along the Z-axis and moves the battery cell above the CCD positioning, where the CCD assembly positions the battery cell. Step 3: After the battery cell is positioned, the swing arm multi-axis robot component 1 moves the battery cell to the top of the shaping platform. Through the dual lifting component 2, a single cylinder descends and places one battery cell at a time. Then, the cylinder is replaced to place another battery cell. Step 4: After all the battery cells on the suction cups are in place, the swing-arm multi-axis robot component 1 moves above the magazine bin to prepare for the next round of loading.

[0028] It should be noted that the loading and unloading processes of this dual-station suction cup loading and unloading mechanism for pouch batteries are reversed, but the principle is the same.

[0029] Based on the above-mentioned dual-station suction cup loading and unloading mechanism for pouch batteries, this utility model also provides: A production line comprising the aforementioned dual-station suction cup loading and unloading mechanism for pouch batteries.
