Description

Electrode production system for secondary batteries

[0001] The present invention relates to a system for producing electrodes for secondary batteries.

[0002] In general, a chemical battery is a battery that includes a positive electrode, a negative electrode, and an electrolyte and generates electrical energy through a chemical reaction. This can be divided into a primary battery that is used for disposable purposes and a secondary battery that can be recharged and discharged, allowing for repeated use.

[0003] The use of secondary batteries is gradually increasing due to their rechargeable nature. Among these secondary batteries, lithium secondary batteries boast a high energy density per unit weight, making them widely used as power sources for electronic communication devices and in high-power hybrid vehicles.

[0004] The electrodes used in these secondary batteries are used as the positive and negative electrodes of the battery and are used to electrically connect the battery and the outside of the battery.

[0005] Electrode tabs can be formed by performing notching at regular intervals on the electrode.

[0006] The notched electrode is sealed in the form of a pouch or a square or cylindrical can in a stack process and manufactured into a secondary battery.

[0007] The electrode material, wound in a reel shape, is unwound from the unwinding section and fed into the notching section. A plurality of electrode tabs are then formed continuously at regular intervals on the electrode material. The electrodes with tabs formed can be rewinded into a reel shape or cut into a specific size and transported through the transport section to be loaded into a magazine.

[0008] The transport unit includes a belt having a plurality of suction holes formed therein and a belt drive unit that moves the belt. The electrodes with tabs formed therein are attracted to the belt and moved toward the magazine. At this time, the belt is positioned above the electrodes, and the electrodes are not removed due to the suction force, and are transported to the location where the magazine is located.

[0009] At this time, before the electrode reaches the magazine, it is determined whether the electrode is defective or good after notching, and only good products are transferred to the magazine side, and defective products are separated from the belt and dropped through a separate pusher unit.

[0010] However, when a defective product is separated from the belt, the suction holes that held the defective product open, allowing air to flow in through the opened suction holes, weakening the belt's suction power. When removing a defective product from the belt, whether the suction is released or maintained without releasing it, the suction holes that held the defective product open, inevitably weakening the belt's suction power. This weakening of the belt's suction power can cause the electrode to fall off the belt.

[0011] When dropping a defective product, even if the suction is switched OFF and then ON again, the belt moves at such a fast speed that the electrode falls off the belt before the suction to hold the electrode is maintained.

[0012] The purpose of the present invention is to provide a secondary battery electrode production system that can prevent electrodes from falling off a belt due to insufficient suction power by maintaining the suction state of adjacent electrodes even when the suction holes that had been sucking up defective electrodes are opened when dropping defective electrodes.

[0013] An embodiment can provide a secondary battery electrode production system including a conveying unit for conveying an electrode, wherein the conveying unit passes through a first region for unloading the electrode and a second region for loading or holding the electrode, the conveying unit includes a suction drive unit, the suction plate, a belt moving along the suction plate, and a plurality of suction blocks coupled to the belt, the suction plate including a plurality of first passages that are partitioned from each other, each of the suction blocks including a second passage and a first hole connected to the second passage, the belt including a second hole aligned with the first hole, and the first hole of the suction block located in the first region among the plurality of suction blocks is communicated with one of the plurality of first passages, and the first hole of the suction block located in the second region is communicated with another one of the plurality of first passages.

[0014] The above first euro is arranged in a plurality of rows, and the first hole of the suction block located in the first region and the first hole of the suction block located in the second region can be connected and arranged in different rows.

[0015] The above suction block may include a block body including the second flow path and the first hole, and a suction tip coupled to the block body and communicating with the second flow path to make contact with the electrode.

[0016] The first euro is arranged in a plurality of rows, the suction plate includes an inlet connected to the suction drive unit, and the inlet can be arranged in alignment with the rows.

[0017] Along the direction of progression of the electrode, it includes a loading area for loading the electrode, a first inspection area for performing a primary inspection on the electrode loaded in the loading area, and a first unloading area for discharging the electrode determined to be defective in the first inspection area, wherein the first area may be the first unloading area, and the second area may be the loading area and the first inspection area.

[0018] The apparatus may include a second inspection area for performing a second inspection on electrodes not discharged from the first unloading area, and a second unloading area for loading electrodes inspected in the second inspection area into a magazine, wherein the first area may be the second unloading area, and the second area may be the second inspection area.

[0019] The first euro may be arranged in a plurality of rows, and the suction drive unit may include a plurality of suction units each communicating with the first euro arranged in a plurality of rows.

[0020] The above suction driving unit can sequentially release the suction of the plurality of suction units in the first region.

[0021] The suction plate includes a first protrusion protruding from the lower surface, and the first flow path is arranged in the first protrusion and can be opened toward the belt from the first protrusion.

[0022] The belt may include a second groove in which the second hole is arranged, the first protrusion may be arranged in the second groove, and the second groove may be arranged along the first flow path.

[0023] According to an embodiment, when unloading a defective electrode, even if the suction holes that were being suctioned are opened, there is an advantage in that the suction state of the adjacent electrode is maintained, thereby preventing the electrode from falling off the belt due to insufficient suction force.

The suction of the suction block (400) connected to the first flow path (U11) arranged in the first row (N1) can be controlled through the first suction unit (110).

[0094] Fig. 12 is a drawing showing a state in which some of the multiple connecting holes (CH) of the suction plate (200) and the first flow path (U1) are connected.

[0095] Referring to Fig. 12, a third connecting hole (CH3) is connected to the first flow path (U13) arranged in the third column (N3). The first flow path (U13) arranged in the third column (N3) is connected to the third suction unit (130) through the third connecting hole (CH3). The suction of the suction block (400) connected to the first flow path (U13) arranged in the third column (N3) can be controlled through the third suction unit (130).

[0096] Fig. 13 is a drawing showing a state in which the suction block (400) arranged in the fifth column (N5) and the suction plate (200) are connected to the first flow path (U1).

[0097] Referring to Fig. 13, the first flow path (U1) arranged in the fifth column (N5) is connected to the second hole (H2) of the belt (300) arranged in the fifth column (N5). In addition, the second hole (H2) of the belt (300) arranged in the fifth column (N5) is connected to the first hole (H1) of the suction block (400) arranged in the fifth column (N5). Through the first hole (H1), the first flow path (U1) and the second flow path (U2) are connected, and ultimately, the first flow path (U1) and the suction tip (420) are connected.

[0098] Fig. 14 is a drawing showing a state in which the suction block (400) arranged in the fourth column (N4) and the suction plate (200) are connected to the first flow path (U1).

[0099] Referring to Fig. 14, the first flow path (U1) arranged in the fourth column (N4) is connected to the second hole (H2) of the belt (300) arranged in the fourth column (N4). In addition, the second hole (H2) of the belt (300) arranged in the fourth column (N4) is connected to the first hole (H1) of the suction block (400) arranged in the fourth column (N4). Through the first hole (H1), the first flow path (U1) and the second flow path (U2) are connected, and ultimately, the first flow path (U1) and the suction tip (420) are connected.

[0100] Although not shown in the drawing, the suction blocks (400) arranged in the first column (N1), second column (N2), and third column (N3) are also connected to the first flow path (U1) in the same manner.

[0101] In this way, since the components connected to the suction block (400) are physically separated, the suction state of the first area (A1) from which the electrode (S) is separated does not affect the suction state of the second area (A2). That is, even if the electrode (S) is separated by the suction tip (420) in the first unloading area (A11) and the suction block (400) is opened, the suction state of the suction block (400) in the first inspection area (A22) adjacent to the first unloading area (A11) or the suction state of the suction block (400) in the second inspection area (A23) is not affected, so the suction state can be maintained in the first inspection area (A22) and the second inspection area (A23).

[0102] Meanwhile, the suction drive unit (100) can independently control each suction unit (110, 120, 130, 140, 150) in the first area (A1).

[0103] For example, in the first unloading area (A11), when a suction block (400) having a first hole (H1) arranged in the third column (N3) is located, the suction driving unit can control the suction unit (130) connected to the first flow path (U13) corresponding to the third column (N3) to release the suction in order to discharge a defective electrode (S) in the first unloading area (A11).

[0104] Next, the suction drive unit (100) can sequentially control the suction unit (140) connected to the first flow path (U14) corresponding to the fourth row (N4) in the first unloading area (A11). Then, it can control the suction unit (150) connected to the first flow path (U15) corresponding to the fifth row (N5) in the first unloading area (A11). Then, it can control the suction unit (110) connected to the first flow path (U1) corresponding to the first row (N1) in the first unloading area (A11). Then, it can control the suction unit (120) connected to the first flow path (U12) corresponding to the second row (N2) in the first unloading area (A11).
