Background
The traditional diaphragm cutting in the lithium ion battery industry adopts a sawtooth type cutter to cut, and after the cutter is worn, the edge of the diaphragm cut is easily torn, so that potential safety hazards are left for subsequent finished batteries. Particularly in the field of high-energy-density battery type diaphragms, the surface of the diaphragm is coated with a high-hardness ceramic coating, and the cutting edge of a serrated cutter is very easy to wear, so that the ceramic diaphragm is seriously torn, and huge potential safety hazards are left for lithium battery products. Lithium cell diaphragm cuts needs a stable long-life cutting device, guarantees under the adaptable continuous high-efficient operation condition that the diaphragm cuts and does not have the tear burr-free phenomenon to can reduce tool changing time and reduce the clean operating time of inefficiency, promote product quality and production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the phenomenon that the burrs of a cutter are easily torn at the edge of a lithium battery diaphragm cut by the cutting device in the prior art is solved, the diaphragm hot-cutting device can guarantee that the cutter does not tear under the continuous and efficient operation condition, the cutter changing time can be shortened, the inefficient cleaning work time can be shortened, and the product quality and the production efficiency can be improved.
The technical solution of the utility model is to provide a diaphragm hot cutting device, its special character lies in, include:
the U-shaped fixing frame, the top and the bottom of two sides of the U-shaped fixing frame are respectively provided with a rotating wheel, hot cut wires surrounding the rotating wheels, and a heating device is arranged at the top of a notch of the U-shaped fixing frame;
the rotating wheel comprises a motor driving wheel and three auxiliary rotating steering wheels;
a tensioning wheel device is arranged on the left side of the U-shaped fixing frame, and the tensioning wheel device enables the hot shredding to surround the rotating wheel in a tensioned state similar to a square shape;
the bottom end of the U-shaped fixing frame is rigidly connected with the air cylinder, and the U-shaped fixing frame can integrally move back and forth under the action of the air cylinder to complete the hot cutting work of the diaphragm.
Preferably, the heating device can adopt different types of heating modes according to different situations: infrared irradiation heating and contact heating; different heating control modes can be adopted: constant temperature control and constant heating time control.
Preferably, a roller cleaning brush is further arranged on one side of the U-shaped fixing frame, and the hot cut wires are in close contact with the roller cleaning brush during rotation to clean the surfaces of the hot cut wires.
Preferably, the roller cleaning brush is selectable according to the characteristics of the cutting target: sponge material, nylon, wool felt.
Preferably, the motor driving wheel can rotate clockwise or anticlockwise according to the requirement of a user.
Compared with the prior art, the beneficial effects of the utility model are that:
⑴, the diaphragm cutting is ensured to be free from tearing and burr under the condition of continuous and efficient operation of the lithium battery diaphragm cutting;
⑵ reducing the time for changing tools and the cleaning time;
⑶, the product quality and the production efficiency are improved, and the method is suitable for large-scale automatic production lines.
