Description

Technical Field

[0001] The utility model relates to the technical field of battery aluminum-plastic shell production, in particular to a battery aluminum-plastic shell cutting mechanism. Background Art

[0002] Battery aluminum-plastic film shell is a composite soft packaging shell material used to encapsulate lithium batteries. It plays an important role in protecting lithium battery cells. The aluminum-plastic film is mainly divided into three layers from the outside to the inside, namely the nylon layer, the aluminum foil layer and the heat-sealing layer. The three layers are bonded together by adhesive to form an aluminum-plastic film. These three layers of materials are compounded together through a specific process to form a battery aluminum-plastic film shell, providing safe protection for lithium batteries.

[0003] Punching holes is the first process of forming battery aluminum-plastic film shells in the production of battery aluminum-plastic film shells. According to the design of the battery's external dimensions, a forming mold is used to punch holes on the aluminum-plastic film to accommodate the battery cell under heating. After the punching operation is completed, the punched aluminum-plastic film needs to be cut to form a single aluminum-plastic film battery shell. However, the existing punched aluminum-plastic film cutting process still has manual or semi-mechanical processing methods, which has low processing efficiency and affects production efficiency. Therefore, it is necessary to improve it. Utility Model Content

The aluminum-plastic film with a dented shape is conveyed to the guide mechanism by a feeding device after the aluminum-plastic film is dented through a denting operation. The aluminum-plastic film with a dented shape is conveyed to the cutting knife along the guide mechanism.

[0023] When in use, the rolled aluminum-plastic film is formed into a pitted aluminum-plastic film after the pitting operation, which is transported to the guide mechanism 1 by the feeding equipment, and the pitted aluminum-plastic film is transported to the cutting knife 2 along the guide mechanism 1, and the pulling manipulator 3 clamps the pitted aluminum-plastic film close to the cutting knife 2 and pulls it a certain distance away from the cutting knife 2 and then stops. After the pulling manipulator 3 stops, the guide mechanism 1 presses the pitted aluminum-plastic film, and then the cutting knife 2 cuts the pitted aluminum-plastic film, and the pulling manipulator 3 releases the cut pitted aluminum-plastic film, and the pitted aluminum-plastic film is carried on the material receiving platform 21, and the handling manipulator 4 transports the pitted aluminum-plastic film on the material receiving platform 21 to the slitting device 5 for slitting, so that the pitted aluminum-plastic film is cut to form a single aluminum-plastic film battery shell, and the pitted aluminum-plastic film slitting process is completed in a fully mechanized manner, thereby improving production efficiency.

[0024] The guide mechanism 1 of this embodiment includes a guide frame 11, a holding block 12, a first actuator 13, a guide rail 14 and a guide member 15. The first actuator 13 is a cylinder, an oil cylinder and a linear slide module. The guide frame 11 is arranged on the side of the cutting knife 2 away from the material pulling robot 3, and the first actuator 13 drives the holding block 12 to slide up and down along the height direction of the guide frame 11. The guide rail 14 is arranged between the guide frame 11 and the holding block 12, and the guide member 15 is arranged at one end of the holding block 12 facing the cutting knife 2. The lower part of the guide member 15 is provided with a guide groove 151, and the guide groove 151 is covered above the guide rail 14.

[0025] After the material pulling robot 3 stops, the first actuator 13 drives the holding block 12 to slide downward in the height direction of the guide frame 11, and the holding block 12 presses the pitted aluminum-plastic film on the guide rail 14, so that the guide mechanism 1 presses the pitted aluminum-plastic film, which is convenient for the cutting knife 2 to cut the pitted aluminum-plastic film. After the pitted aluminum-plastic film is cut, the first actuator 13 drives the holding block 12 to slide in the height direction of the guide frame 11, so that the pitted aluminum-plastic film can be transported along the guide rail 14 toward the cutting knife 2, which is convenient for the material pulling robot 3 to clamp the pitted aluminum-plastic film close to the cutting knife 2 and pull it a certain distance away from the cutting knife 2 before stopping.

[0026] The material receiving platform 21 of this embodiment is provided with a second actuator 22, which is a pneumatic cylinder, an oil cylinder and a linear slide module. The second actuator 22 drives the material receiving platform 21 to rise and fall along the height direction of the cutting blade 2, so that the material receiving platform 21 can adjust its height. The material receiving platform 21 is provided with a bearing cavity 211, which matches the shape of the punched aluminum-plastic film. The bearing cavity 211 reduces the displacement of the punched aluminum-plastic film, so that the handling robot 4 can be used for transportation.

[0027] The material pulling manipulator 3 of this embodiment includes a sliding seat 31, a clamping head 32 and a third actuator 33. The clamping head 32 is a pneumatic finger or a finger manipulator, and the third actuator 33 is a cylinder, an oil cylinder and a linear slide module. The clamping head 32 is used to clamp the punching aluminum-plastic film. The clamping head 32 is fixed to one end of the sliding seat 31 close to the cutting knife 2, and the third actuator 33 drives the sliding seat 31 to approach or move away from the cutting knife 2.

[0028] When in use, the third actuator 33 drives the sliding seat 31 to approach the cutting knife 2, and the clamping head 32 clamps the punched aluminum-plastic film. The third actuator 33 drives the sliding seat 31 away from the cutting knife 2 and stops, so that the pulling manipulator 3 approaches the cutting knife 2 to clamp the punched aluminum-plastic film and pulls it a certain distance away from the cutting knife 2 and then stops. After the cutting knife 2 cuts the punched aluminum-plastic film, the clamping head 32 releases and cuts the punched aluminum-plastic film. This is repeated, so that the punched aluminum-plastic film is transported to the cutting knife 2 along the guide mechanism 1.

[0029] In this embodiment, a relief groove 212 is arranged at one end of the material receiving platform 21 facing the clamping head 32, and the relief groove 212 facilitates the clamping head 32 to clamp the punched aluminum-plastic film.

[0030] The handling robot 4 of this embodiment includes a turntable 41, a fourth actuator 42, a rotating arm 43, a first suction cup 44, a fifth actuator 45, a second suction cup 46 and a sixth actuator 47.

[0032] When the cut dented aluminum-plastic film is carried on the carrying cavity 211, the fourth actuator 42 drives the turntable 41 and the rotating arm 43 to approach the material receiving platform 21. If the first suction cup 44 is above the material receiving platform 21, the fifth actuator 45 drives the first suction cup 44 to descend close to the material receiving platform 21 and suck the dented aluminum-plastic film carried on the carrying cavity 211. The fifth actuator 45 drives the first suction cup 44 to rise away from the material receiving platform 21. The turntable 41 rotates 180 degrees, so that the rotating arm 43 also rotates 180 degrees, so that the first suction cup 44 and the second suction cup 46 are interchanged. The fourth actuator 42 drives the turntable 41 to rotate, so that the rotating arm 43 is away from the material receiving platform 21, so that the first suction cup 44 is above the slitting device 5. The fifth actuator 45 drives the first suction cup 44 to descend close to the slitting device 5 and release the dented aluminum-plastic film to the slitting device 5, so that the slitting device 5 can slit the dented aluminum-plastic film, so that the dented aluminum-plastic film is cut to form a single aluminum-plastic film battery shell.

[0033] Similarly, when the second suction cup 46 is above the material receiving platform 21, the sixth actuator 47 drives the second suction cup 46 to descend close to the material receiving platform 21 and suck the punched aluminum-plastic film carried in the carrying cavity 211. By rotating the turntable 41 180 degrees, the positions of the first suction cup 44 and the second suction cup 46 are interchanged, and the sixth actuator 47 drives the second suction cup 46 to descend to release the punched aluminum-plastic film to the slitting device 5.

The slitting negative pressure table 51 is provided with a slitting groove 511, and the seventh actuator 53 drives the cutting knife 52 to slide along the slitting groove 511.

[0035] When in use, the fifth actuator 45 drives the first suction cup 44 to descend close to the slitting negative pressure platform 51 and press the punched aluminum-plastic film on the slitting negative pressure platform 51, or the sixth actuator 47 drives the second suction cup 46 to descend close to the slitting negative pressure platform 51 and press the punched aluminum-plastic film on the slitting negative pressure platform 51, and the slitting negative pressure platform 51 also sucks the punched aluminum-plastic film through negative pressure at the same time, and the seventh actuator 53 drives the cutter 52 to slide along the slitting groove 511 to cut the punched aluminum-plastic film, so that the punched aluminum-plastic film is cut to form a single aluminum-plastic film battery shell.

[0036] After the punching of the aluminum-plastic film is completed, the first suction cup 44 releases the aluminum-plastic film battery shell, and the fifth actuator 45 drives the first suction cup 44 to rise away from the slitting negative pressure platform 51 or the second suction cup 46 to release the aluminum-plastic film battery shell, and the sixth actuator 47 drives the second suction cup 46 to rise away from the slitting negative pressure platform 51, so as to facilitate the transportation of the aluminum-plastic film battery shell to the next process for processing.

[0037] The first suction cup 44 and the second suction cup 46 of this embodiment are both provided with a knife groove 48 corresponding to the slitting groove 511. When the seventh actuator 53 drives the cutting knife 52 to slide along the slitting groove 511 through the knife groove 48, the cutting knife 52 extends into the knife groove 48 to ensure that the punched aluminum-plastic film is cut off.
