It is about.

In general, as the light weight and high functionality of portable wireless devices such as a video camera, a portable telephone, a portable computer, and the like progress, a lot of researches have been conducted on secondary batteries used as driving power. Such secondary batteries include, for example, nickel cadmium batteries, nickel hydrogen batteries, nickel zinc batteries, and lithium secondary batteries. Among them, lithium secondary batteries are rechargeable, small and large in capacity, and are widely used in advanced electronic devices because of their high operating voltage and high energy density per unit weight.

The lithium secondary battery includes a bare cell and a protective circuit board. Most of the bare cells are formed by accommodating an electrode assembly consisting of a positive electrode, a negative electrode, and a separator, usually in a can made of aluminum or an aluminum alloy, closing the can with a cap assembly, and injecting and sealing an electrolyte solution into the can. The can may be formed of iron, but when it is formed of aluminum or an aluminum alloy, light weight of the battery may be achieved due to the light property of aluminum, and may not be corroded even when used for a long time under high voltage.

The protective circuit board is connected to the positive and negative electrodes of the bare cell by a plate-shaped conductor, commonly called a lead plate. The protective circuit board controls the charging process and the discharging process of the lithium secondary battery, and prevents ignition or explosion due to overcharge or overdischarge due to an abnormality of the lithium secondary battery itself.

The lithium secondary battery is formed when the protective circuit board is molded with a molding resin and coupled to the bare cell, or the bare cell and the protective circuit board are embedded together in an outer case. In particular, the lithium secondary battery in which the final appearance is formed by the outer case of the lithium secondary battery is called a pack type lithium secondary battery.

Will come in contact with The performance measuring unit 110 evaluates the performance of the lithium secondary battery 10 in contact with the performance measuring terminal 120 to evaluate whether or not it is good. While the performance of the lithium secondary battery 10 is evaluated, the upper and lower battery transport means 140 is transferred to the label adhesive unit 300 by the battery left and right transport means 150, and when the performance evaluation is completed, the seating plate It is transferred to 312 and seated. The lithium secondary battery 10 transferred to the seating plate 312 is transferred to the fixed plate 322 by the battery transfer means 310. When the performance of the transferred lithium secondary battery 10 is good, the label supply unit 200 supplies the label and attaches it. If the performance is poor, the battery discharge means 330 operates to the conveyor belt 50. Will be discharged.

The label supply unit 200 adjusts only one label 6 supplied in a roll state to the adsorption block 230 and adjusts the adsorption position to be constant by the battery position adjusting means 160. The label 6 is transferred to the label adhesive unit 300 together with the adsorption block 230 by the block transfer means 240.

The battery fixing means 320 fixes the lithium secondary battery 10 transferred to the fixing plate 322 by the fixing block 326 and the fixing means 328. The label adhesive unit 300 is to adhere the label to the upper surface of the fixed lithium secondary battery (10). When the label 6 is adhered to the upper surface of the lithium secondary battery 10, the battery fixing means 320 does not fix the lithium secondary battery 10. The battery discharge means 330 transfers the fixed plate 322 to the other side to discharge the lithium secondary battery 10 to the upper surface of the conveyor belt 50.

The performance test and label adhesion process of the label as described above is controlled by the controller 400, the performance test and the label adhesion process for a plurality of lithium secondary battery 10 may be performed sequentially.
