Description

Un-loading device for slitters}

The present invention relates to unloading equipment for slitters.

In general, types of secondary batteries include nickel cadmium batteries, nickel hydrogen batteries, lithium ion batteries, and lithium ion polymer batteries. These secondary batteries are used not only for small products such as digital cameras, P-DVDs, MP3Ps, mobile phones, PDAs, portable game devices, power tools, and E-bikes, but also for large products that require high power, such as electric vehicles and hybrid vehicles, and surplus power generation. It is applied and used to a power storage device for storing power or renewable energy and a power storage device for backup.

In order to manufacture an electrode assembly, a cathode, a separator, and an anode are prepared and stacked. Specifically, when a cathode and an anode are manufactured, and a separator is interposed between the manufactured anode and cathode and stacked, unit cells are formed, and the unit cells are stacked on each other. , an electrode assembly is formed. In addition, when the electrode assembly is accommodated in a specific case and an electrolyte solution is injected, a secondary battery is manufactured.

In order to manufacture electrodes such as positive and negative electrodes, a coating process of applying the positive electrode active material slurry to the positive electrode current collector and then applying the negative electrode active material slurry to the negative electrode current collector is first performed. Then, after preheating the electrode plate, a rolling process of passing the electrode plate between a pair of rolling rolls heated to a high temperature is performed. By doing so, it is possible to improve the capacity density of the electrode and improve the adhesion between the electrode current collector and the slurry. After the rolling process is completed, a slitting process of cutting the electrode plate into a predetermined width using a slitter equipment is performed.

The slitter equipment includes a rewinder for winding the cut electrode plates around a bobbin to form a plurality of electrode rolls, and an unloading device for unloading the plurality of electrode rolls from the rewinder. The above "unloading" refers to loading the electrode roll.

Meanwhile, the plurality of electrode rolls unloaded by the unloading equipment must be unloaded again to a moving means to perform a post-process such as packaging.

Conventionally, an operator directly takes out a plurality of electrode rolls unloaded in unloading equipment, unloads them in a moving means, and then moves to a post-processing site. However, when the operator manually takes out the electrode, the operator's fatigue is high, and there is a concern that a safety accident in which the operator's hand is caught between the electrode rolls may occur.

According to the present invention, as a take-out unit capable of automatically taking out a plurality of unloaded electrode rolls is provided, the take-out time is shortened compared to the existing manual take-out work, and unloading for slitters can improve worker fatigue and prevent worker safety accidents. Make the provision of equipment the task you are trying to solve.

In order to solve the above problems, according to one aspect of the present invention, a plurality of electrode rolls are unloaded from a slitter rewinder for winding an electrode plate that has undergone a slitting process around a bobbin to form a plurality of electrode rolls. A loading device comprising: a body housing positioned adjacent to the rewinder for the slitter; an unloading unit connected to the body housing and unloading a plurality of electrode rolls from the rewinder for the slitter; and a take-out unit for taking out the plurality of unloaded electrode rolls.

As described above, as the unloading equipment according to the present invention is provided with a take-out unit capable of automatically taking out the unloaded electrode roll, the take-out time is reduced compared to the conventional manual take-out performed by the operator manually, and the safety of the operator It is effective in preventing accidents.
