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. Consequently, the hot device of cutting of lithium cell diaphragm has appeared on the market, but these hot devices of cutting adopt continuous heating mostly, and cutter life is short, and the structure is more complicated, uses inconveniently, and the electric quantity consumes greatly when carrying out the hot cutting, is unfavorable for energy-conservation, and the cutting effect is general, can't satisfy the market demand.

Disclosure of Invention

In order to overcome the technical defect, the utility model aims at providing a simple structure, convenient to use, long service life does benefit to energy-conservation, and the cutting effect is good, can satisfy the lithium cell diaphragm hot cutting device of market demand.

In order to achieve the purpose, the invention is realized by the following technical scheme:

the utility model provides a lithium battery diaphragm hot cutting device, includes the mount pad, fixes locating cylinder mount pad on the mount pad with locate cylinder in the cylinder mount pad, the telescopic link one end fixedly connected with conducting block of cylinder, the fixed cutting mechanism that is equipped with on the conducting block, the telescopic link of cylinder drives and fixes locating on the conducting block cutting mechanism back-and-forth movement.

Further, the cutting mechanism comprises a knife holder and a knife edge.

Furthermore, the cutting edge can be detachably arranged on the cutter holder.

Further, the tool apron is fixedly arranged on one side of the conductive block through a connecting rod.

To sum up, the utility model has the advantages that: this hot cutting device, including the mount pad, the cylinder mount pad on the mount pad is located to the fixed cylinder that locates on the mount pad and locate in the cylinder mount pad, and the telescopic link one end fixedly connected with conducting block of cylinder is fixed on the conducting block and is equipped with cutting mechanism, and the telescopic link of cylinder drives the fixed cutting mechanism back-and-forth movement of locating on the conducting block, and cutting mechanism includes blade holder and cutting edge, and the cutting edge can be dismantled and locate on the blade holder. Cutting edge replaceable design on the cutting mechanism has prolonged its life, and when carrying out the hot cutting, through carrying out the ohmic heating to the conducting block, the conducting block passes to the cutting device with heat energy again and goes up the hot cutting to the lithium cell diaphragm, and the cutting is accomplished the back, can cut off the power supply to the conducting block, does benefit to energy-conservation, and its simple structure not only, convenient to use, long service life does benefit to energy-conservation, and cutting effect is good, also can satisfy the market demand.
