Technical Field
The present invention relates to an apparatus and method for aligning a label to be attached to a battery.
More particularly, the present invention relates to an apparatus and method for aligning a tag attached to a battery using a sensor.
Background
Recently, rechargeable secondary batteries have been widely used as energy sources for wireless mobile devices. In addition, the secondary battery has attracted attention as an energy source for electric vehicles, hybrid electric vehicles, and the like, and has been proposed as an alternative to solve air pollution and the like of existing gas vehicles, diesel vehicles, and the like using fossil fuel. Therefore, the kinds of applications using the secondary battery are various due to the advantages of the secondary battery, and the secondary battery is expected to be applied to more fields and products than now in the future.
Such secondary batteries may also be classified into lithium ion batteries, lithium ion polymer batteries, lithium polymer batteries, and the like, according to the configurations of electrodes and electrolytes, in which the lithium ion polymer batteries, which have a low possibility of electrolyte leakage and are easily manufactured, are increasingly used.
In general, secondary batteries are classified into cylindrical and prismatic batteries, each of which an electrode assembly is embedded in a cylindrical or prismatic metal can, and pouch type batteries, each of which an electrode assembly is embedded in a pouch type case formed of an aluminum laminate sheet, according to the shape of a battery case.
It can be said that the best advantage of a mobile device such as a laptop PC is convenient portability, and the secondary battery plays the most important role in achieving portability.
Secondary batteries have been used as energy sources for various electronic products as well as various mobile devices, but various combustible materials are embedded in the secondary batteries. Therefore, there is a danger of heating, explosion, etc. due to overcharge, overcurrent, other physical external impacts, etc., and in order to solve this problem, a Positive Temperature Coefficient (PTC) element, a Protection Circuit Module (PCM), etc. are mounted in a state of being connected to the battery cell as a safety element that can effectively control abnormal states such as overcharge and overcurrent.
A battery pack equipped with components such as a safety element and a PCM module on a battery case is manufactured through a number of complicated processes for accommodating an electrode assembly in the battery case, injecting and sealing an electrolyte, and attaching a label indicating the specifications of the battery pack to the outside of the case.
Conventionally, when a tab sheet is manually attached to a case of a secondary battery or attached using a tab attaching device, an alignment state is checked by using a block, and when tab alignment is defective, the tab is realigned by pushing the tab with a physical block.
Therefore, when the labels are realigned by pushing with the physical block, in the case of label peeling, there is a problem that the labels are not realigned but pushed to cause wrinkles or overlaps.

2. Battery label attaching method according to embodiment of the invention
Fig. 4 is a flowchart illustrating a sequence of a battery label attaching method according to an embodiment of the present invention.
A battery label attaching method according to an embodiment of the present invention is described below with reference to fig. 4.
According to an embodiment of the present invention, a method for attaching a tag to a battery includes: a label separating operation (S100) for separating the protective paper and the label and placing the label on the label holder; a label alignment state checking operation (S200) for checking an alignment state of the label separated in the label separating operation, wherein when a normal alignment state is checked in the label alignment checking operation (S200), a label attaching operation (S300) for attaching the label to the battery may be performed, and when a defective alignment state is checked in the label alignment state checking operation (S200), a label alignment operation (S210) for aligning the label may be performed, and then a label attaching operation (S300) is performed.
More specifically, the tag alignment state checking operation (S200) may be an operation of checking the alignment state by using a first sensor spaced a preset distance to the left with respect to the servo robot moving the tag holder and a second sensor spaced a preset distance to the right with respect to the servo robot moving the tag holder.
More specifically, in the tag alignment state checking operation (S200), when the tag is detected by one of the first sensor or the second sensor, it may be determined that the tag alignment is defective, and when the tag is detected by both the first sensor and the second sensor, it may be determined that the tag alignment is normal.
Meanwhile, when it is determined that the tag alignment is normal in the tag alignment state checking operation (S200), the tag alignment operation (S210) may not be performed.
Meanwhile, when it is determined that the tab alignment is defective in the tab alignment state checking operation (S200), a tab alignment operation (S210) may be performed.
More specifically, in the label aligning operation (S210), the rotating member is rotated counterclockwise by a predetermined angle to align the label when the label is detected only by the first sensor, and the rotating member is rotated clockwise by a predetermined angle to align the label when the label is detected only by the second sensor.
Meanwhile, the predetermined rotation angle may be a preset angle, or may be differently set according to the amount of light detected by the first sensor or the second sensor when the first sensor or the second sensor can detect the amount of light.
For example, the rotating member may be rotated by a small angle when a large amount of light is detected, and may be rotated by a large angle when a small amount of light is detected.
Meanwhile, the technical idea of the present invention has been specifically described with respect to the above embodiments, but it should be noted that the foregoing embodiments are provided only for illustration and not to limit the present disclosure. In addition, various embodiments may be provided to allow those skilled in the art to understand the scope of the present invention.
