The present invention relates to a battery production method and a secondary battery produced by the method, and more particularly, a logistics management system for battery production using a radio frequency identification (RFID) chip and a tag used in the system. A secondary battery having a wireless communication recognition chip.

In production of batteries, too many kinds of various parts are used. The process of bringing these parts into the production line, moving them, and combining them together to form a finished battery product also needs to be a shank in many respects, and a lot of effort is put into its management.

In the case of inputting materials in the conventional battery production process, or managing the production quantity or the shipment quantity, the material management is performed manually by using a normal check sheet or by a dedicated sensor using the appearance characteristics of the object. It is often done.

In addition, as a method of obtaining data related to process control, a method of collecting and managing data by attaching a barcode to an object to be processed is frequently used. However, data collection management using barcodes must not only attach a barcode to the item but also scan the barcode with a barcode reader to recognize the attached barcode. And, it can be used only when the corresponding object in the step appears in appearance, and cannot be used when the barcode attached to the object is wrapped in another opaque material.

Therefore, it is difficult to manage all objects through bar codes, and in particular, it is not easy to continuously manage one object throughout the production stage. As a result, individual management through bar codes is used to manage only important processes separately for important parts.

Therefore, there is a demand for a system capable of comprehensively managing production process management, parts supply and demand, product production and shipment quantity to increase production efficiency.

The present invention is to solve the problems in the conventional management system as described above, it is possible to cover the entire process for the individual parts through a simple operation of the attachment of a tag having a wireless communication recognition chip, the process It is an object of the present invention to provide a secondary battery having a logistics management system that can be used for quality control and a wireless communication recognition chip to be produced using the system.

Logistics management system for battery production of the present invention for achieving the above object,

A tag or transponder attached to a management object and having a built-in antenna and an integrated circuit chip, a reader for communicating with the tag, and a host processing apparatus for comprehensive management by receiving information of the reader.

An antenna for communicating with the tag may be formed in the reader itself, or information may be shared with the reader, but an antenna having a separate body may be formed.

In the present invention, the tag should also have an appropriate size for attachment, and the object to be managed preferably has a proper size, such as a protective circuit module or a case of a bare cell, rather than a very small and limited micro component. The case may refer to a pouch of a pouch bare cell or a square can or a cylindrical can of a can-type battery.

In the present invention, the tag is already attached at the time of wearing the corresponding parts, that is, the management object is preferably used for management, but may be attached at any required time after receipt and can be used for logistics and process management at a later stage.

Meanwhile, in the present invention, the tag may be attached to the corresponding part or the finished battery, but may be attached to a pallet for carrying a part or a cart for moving parts rather than individual parts.

In another aspect of the present invention for achieving the above object is characterized in that the secondary battery having a wireless communication recognition chip has at least one wireless communication recognition chip.

At least one of the wireless communication recognition chips provided in the secondary battery of the present invention has its own power source, and the secondary battery itself may be used as its own power source.

At least one of the wireless communication recognition chips included in the secondary battery of the present invention may be a hybrid wireless communication recognition chip that is actively detected when the bare cell is connected to a power source and passively detected when the bare cell does not have its own power source. .

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a diagram illustrating a state in which a tag 30 including a wireless communication recognition chip is attached to the can 11. As shown in the drawing, the tag 30 may be attached to upper and lower portions or sidewall surfaces narrower than the main plane to reduce the thickness of the finished battery. The tag 30 is positioned at the center of the inner surface of the tape 20 to which the adhesive is applied, and is attached to the can 11 in a form similar to a normal barcode, and in a state of being attached, the tag 30 may be wrapped in the tape 20. have. Since the tape 20 may come into contact with an electrolyte or other chemicals, the tape 20 is preferably made of a material having chemical resistance and mechanical strength that does not damage the tag 30.

2 is a diagram illustrating a state in which a tag 130 is attached to a circuit board 100 coupled to a bare cell. The tag 130 may be installed together with the other element 120 on the substrate in the forming of the protective circuit board. The tag may be divided into an active type including a general power source and a passive type which forms a signal by sensing a radio wave received from an external antenna without including a power source, and each type may be used. Meanwhile, in the case of the secondary battery, the tag 130 may be configured as an active type or a complex type using a feature of a kind of a power source as a secondary battery.

That is, the circuit board 100 may be electrically coupled to the bare cell. If the tag 130 is circuitally coupled to the circuit board 100, the circuit board 100 may receive power from the bare cell. Therefore, the tag 130 may be active from the time when the bare cell is charged, and in the previous step, the tag 130 may be simply passive or non-functional.

3 is a conceptual diagram showing a schematic operation and configuration of a secondary battery of the present invention with a tag applied in the system of the present invention, and FIG. 4 is a process of each process in the case where a tag is installed on a can and a protective circuit board, respectively. Is a conceptual schematic diagram of an embodiment of the present system.

Referring to FIGS. 3 and 4, for the can 11 with the tag 230 attached, the receipt (A), the electrode assembly insertion coupling (B), the cap assembly welding coupling (C), the electrolyte injection (D), and the electrolyte solution Processes such as injection hole finish (E) and initial charge discharge (F) are performed separately, and in this step, the reader 220 is installed in each process line. According to the flow of the can 11, the passive tag 230 attached to the can receives the radio signal transmitted from the antenna 225 attached to the reader 220 and sends the converted signal, and the converted signal is again the antenna 225 Is read to the reader 220 through. The reader 220 decodes the read signal and sends the read signal to the host processor 210 through the signal cable 215. The host processor 210 records the information received from the reader 220 in the database 213. .

On the other hand, the active tag 231 is installed on the circuit board 100 together with other elements on the substrate once there is no power supply. Through the core pack battery assembly process (G), the terminal of the active tag 231 is connected to the two electrical terminals of the circuit board 100 to be connected to the bare cell. Therefore, the tag 231 does not function in the receiving step of the protection circuit board, but the tag 231 'receives power from the bare cell and becomes a fully active tag 231' in the step of combining the protection circuit board and the bare cell. Will work.

Therefore, when installing a reader capable of detecting the tag of the protection circuit board from the rear end of the process of forming the core pack by combining the protection circuit board and the bare cell, the tag 231 'of the protection circuit board is detected and at the same time. The tag 230 attached to the bare cell is sensed and the two tags are combined and associated with each other, and the tag of the protection circuit board may be detected without detecting the tag 230 attached to the can of the bare cell. 231 ') can be detected so that it can be seen at which stage in the process or when a particular bare cell or can is currently shipped.

If initial charging and discharging is performed after the core pack is formed, the tags formed on the bare cell and the protection circuit board are detected and associated after the initial charging, and the active tag of the protection circuit board is detected from a later stage. Can be.

In general, passive tags have a narrow sensing range, so antennas and readers are installed close to the line through which cells or components pass through the process, and active tags installed on protective circuit boards start to operate with the process line. By installing an antenna and a reader in a relatively remote place, it is possible to grasp the process movement of the battery of the active tag. For example, when the reader is installed at the exit of the warehouse (H) or at the front door (I), the shipment records may be recorded at the same time for a plurality of secondary batteries in which a plurality of pallets or trucks are loaded.

In this mass movement, high frequency radio waves may be used for transmitting and receiving tags and readers to obtain information clearly, and a host processor may form an agent-based distributed hierarchy structure to process a large amount of tag data.

5 is a block diagram showing a conceptual configuration of a system constituting another embodiment of the present invention.

The difference from the embodiment of FIG. 4 here is that the tag used for the protection circuit board is a hybrid type that can act as both active and passive.

As in the embodiment of Figure 4 for the can is made of a separate process such as receipt (A), electrode assembly insertion coupling (B), cap assembly welding coupling (C), electrolyte injection (D), electrolyte injection opening (E), etc. At this stage, an antenna and a reader are installed near each process line. As the can 11 flows, an imprinted signal of the passive tag 230 attached to the can is read by the reader 220. The reader 220 decodes the read signal and sends the read signal to the host processor 210 via the cable 215, and the host processor 210 records the information received from the reader in the database 213.

On the other hand, the active circuit passive tag 241 is installed on the protective circuit board with other elements on the substrate once there is no power. The terminal of the tag 241 is connected to two electrical terminals with a bare cell of the circuit board 100. Therefore, the tag 241 functions as a passive type in the receiving step of the protective circuit board. In the step of combining the protection circuit board and the bare cell, the tag may receive power from the bare cell to act as an active tag 241 '.

Assuming that the chemical conversion process is performed in the core pack step, since the bare cell is not charged at the initial stage of the bare cell and the protection circuit board, both the tag attached to the can and the tag attached to the protection circuit board operate manually. Done. At this time, when installing a reader that detects the tags of the protection circuit board and the can from the rear end of the process of forming the core pack by combining the protection circuit board and the bare cell, the bare cell is detected at the same time as detecting the tag of the protection circuit board. Detect the tag attached to and associate the two tags. In the subsequent process, until the initial charging process, only the tag mounted on the protection circuit board of the two tags of the core pack is passively detected.

In addition, from the initial charging process, the tag attached to the protective circuit board acts as an active tag and the antenna detects the tag attached to the protective circuit board acting actively. If the tag internal information is shared even when it is passive or active, the tag of the protection circuit board operated passively can maintain the association with the tag attached to the can even in the active state.

From an active point of view, there is no need to place antennas and readers close to the process line to detect tags. In particular, in the process of chemical conversion or in the warehousing and delivery stage of the finished battery, a large number of batteries are often moved together, so it is advantageous to detect the battery through an active tag.

The secondary battery produced using the system of the present invention as described above has at least one wireless communication recognition chip or tag as in one aspect of the present invention. This tag can also be used for logistics management in the distribution of batteries. In addition, depending on the characteristics of the secondary battery, when the secondary battery itself is used as the power source of the tag, even if the tag is an active tag, the secondary battery can function for a considerable period of time when the secondary battery is used. Can be used. For example, if the tag contains active information on the production process in the process of finding the cause of the problem through the report of the consumer, for example, overheating during use or abnormally short life, it is useful for detecting the problem of the process. Can be used.

In the logistics management system for battery production using a wireless communication recognition chip as in the present invention, a tag having a wireless communication recognition chip may be attached to an object at a product or part level to manage parts logistics, and the tag may be recognized. For example, process-related data experienced by an object can be described in the tag itself or in a database associated with a host and associated with the tag, thereby enabling production or process control.

In addition, due to the characteristics of the battery, the tag can be active after a certain step, and unlike the active tag of other products, the active tag is maintained for the life of the battery, so that it can be used for follow-up management such as tracking the cause of an error when a battery problem occurs. have.
