Description

Rechargeable battery jelly roll input accuracy improvement system

The present invention relates to a system for improving the degree of injection of jelly rolls for a secondary battery with a new configuration capable of preventing scratches or holes marks on a jelly roll or misalignment of a jelly roll during a secondary battery manufacturing process.

The secondary battery has an electrode assembly mounted inside a battery case, and the electrode tabs protrude from both ends or one end of the secondary battery. In this case, a jelly roll formed by a winding method with a separator interposed between a plurality of positive and negative plates is referred to as a jelly roll.

The manufacturing process of the secondary battery includes various processes such as a process of transferring a jelly roll, a process of picking up a jelly roll and inserting it into a pouch, and a pouch packaging process in which the jelly roll is inserted.

However, conventionally, there is a problem that scratches or holes are generated on the jelly roll due to frictional force during the alignment process of the jelly rolls of secondary batteries, and there are cases in which charging occurs due to frictional force between the jelly roll and the conveying path during alignment. When such scratches or holes are formed on the jelly roll and a charging phenomenon occurs, the quality of the secondary battery is deteriorated.

In addition, after the secondary battery jelly roll is transferred, the pouch is picked up by gripping the pouch by a pair of forks of the pickup device, and then the jelly roll is inserted into the pouch at the bottom by opening the pair of forks again. When the pair of forks is opened again, the jelly roll is not in a straight position due to the phenomenon that the pouch is pulled by the fork, and a phenomenon that the position is displaced (slip phenomenon) occurs, causing a problem that the jelly roll cannot be properly inserted into the pouch. In other words, when a pair of forks are opened, the jelly roll cannot be prevented from slipping due to the fork when the jelly roll falls, so the jelly roll is twisted when it falls, and if the jelly roll is turned on when falling, the jelly roll cannot be properly inserted into the pouch. In this way, there is a problem that a defect occurs because the jelly roll goes through the sealing process immediately in a state where it is not properly put into the pouch.

An object of the present invention is a new configuration that can expect various desirable results, such as preventing scratches or hole marks on the jelly rolls or misalignment of the jelly rolls during the manufacturing process of the secondary battery in order to improve the quality of the secondary battery. It is to provide a system for improving the degree of input of jelly rolls for secondary batteries.

The present invention is an alignment device; A loading pickup device for picking up the jelly rolls aligned by the alignment device and putting them into a pouch is provided to solve the technical problem by providing a system for improving the input accuracy of the jelly rolls for a secondary battery, characterized in that it comprises.

Since the present invention aligns the jelly rolls in the correct position in the alignment device, the process requiring alignment of the jelly rolls, such as the process of inserting the jelly rolls into the pouch in the manufacturing process of the secondary battery, can be precisely performed. It can also prevent the occurrence of electrification due to friction between the roll and the unloading jig, and when the jelly roll falls into the pouch, the jelly roll is not twisted by the guide unit and the sealing process is properly inserted into the pouch (pouch sealing Process), thus preventing the problem of defects.

The operation and effect of the system for improving the degree of injection of jelly rolls for secondary batteries according to the present invention having the above configuration will be described as follows.

Jelly roll (2) by the pressure of air coming up through a plurality of holes from the bottom of the unloading jig (22) while the jelly roll (2) is on the unloading jig (22) of the alignment device (20) The bottom surface of the unloading jig 22 does not contact the upper surface of the unloading jig 22 and is maintained in a state of floating upward a predetermined distance from the upper surface of the unloading jig 22.

Side alignment units 24 disposed on both sides of the unloading jig 22 are operated while the jelly roll 2 is slightly floating upward from the upper surface of the unloading jig 22. The side alignment unit 24 includes a pair of side alignment members 24SM disposed at positions adjacent to both sides of the unloading jig 22, and the side alignment members 24SM are It is configured to be connected (for example, connected to the cylinder rod of the cylinder), and the pair of side alignment members 24SM are connected to each other by the operation of the moving operation means (the operation of the cylinder rod when the moving operation means is a cylinder) Advance in the opposite direction. Then, while the side alignment protrusion blocks 24PB provided on the pair of side alignment members 24SM are in contact with both sides of the jelly roll 2, the pair of side alignment members 24SM is Since both sides of (2) are pushed, both sides of the jelly roll (2) are aligned on the unloading jig (22). The direction parallel to the length direction of the unloading jig 22 is a predetermined alignment direction of both sides of the jelly roll 2, so that the pair of side alignment members 24SM push both sides of the jelly roll 2 As it is, both sides of the jelly roll 2 may be aligned in a predetermined width direction. At this time, the jelly rolls 2 can be aligned in a predetermined width direction as described above while floating upward from the upper surface of the unloading jig 22 for a predetermined distance.

Meanwhile, the jelly roll 2 is aligned to a predetermined longitudinal position by the operation of the linear alignment unit 26 and the alignment reference unit 28. The linear alignment moving actuating body 26DM of the linear alignment unit 26 is operated. When the linear alignment moving actuator 26DM is configured as a cylinder, the cylinder rod of the cylinder is operated to advance toward the alignment reference unit 28. The linear alignment block 26LB advances toward the alignment reference unit 28 by the movement of the linear alignment moving body 26DM. When the linear alignment moving actuator 26DM is configured as a cylinder, the linear alignment block 26LB is connected to the cylinder rod of the cylinder, so when the cylinder rod of the cylinder is advanced, the linear alignment block 26LB becomes a jelly roll. One end of (2) (that is, one end of which the electrode lead protrudes) is pressed and moved toward the alignment reference part 28. With the linear alignment push piece 26PP protruding from the linear alignment block 26LB in contact with the separator protruding from one end of the jelly roll 2, the jelly roll 2 is aligned with the reference part ( 28). At this time, the jelly roll 2 is pushed toward the alignment reference part 28 by the linear alignment block 26LB while floating upward from the upper surface of the unloading jig 22 for a predetermined distance.

The jelly roll 2 is pushed by the linear alignment block 26LB, and the other end of the jelly roll 2 (that is, the other end from which the other electrode lead protrudes) is placed on the alignment reference unit 28 By contacting and stopping, the jelly roll 2 is aligned to a predetermined longitudinal position. Jelly roll (2) by stopping the advance of the linear alignment block (26LB) while the other end of the jelly roll (2) is in contact with the alignment reference protrusion (28SP) provided in the alignment reference unit (28). Are aligned to the specified longitudinal position.

In summary, in the alignment device 20, the side alignment unit 24 and the linear alignment unit 26 are aligned so that the jelly rolls 2 are spaced a certain distance upward from the top surface of the unloading jig 22. And the jelly roll 2 is aligned in a predetermined width direction and a length direction by the alignment reference unit 28.

Therefore, since the alignment device 20 aligns the jelly rolls 2 to the correct position, alignment of the jelly rolls 2 is the same as the process of injecting the jelly rolls 2 into the pouch in the manufacturing process of a secondary battery. This necessary process can be performed simply and accurately.

At this time, since the jelly roll 2 is moved and aligned while the jelly roll 2 is floating on the unloading jig 22 by air pressure, the jelly roll 2 of the secondary battery is aligned. There is no problem that scratches or holes are generated on the jelly roll 2, and it is also possible to prevent a case where a charge phenomenon occurs due to frictional force between the jelly roll 2 and the unloading jig 22 during alignment. By preventing such scratches or holes from occurring on the jelly roll 2 and preventing the charging phenomenon, it is possible to prevent the quality of the secondary battery from deteriorating. By forming a thin air film as an air bearing for non-contact conveyance by the air rising from the bottom of the unloading jig 22, the jelly roll 2 is floated, and the jelly roll 2 (J/R) is floated and aligned. When (Align) is in progress, the accuracy is increased because it is not affected by the separator. Alignment is performed while the jelly roll 2 is floating on the upper surface of the unloading jig 22, so that the linear alignment push piece 26PP of the linear alignment block 26LB is at one end of the jelly roll 2 By pressing the separator partly out of the part with excessive force, it is crushed, or by pressing the separator partly out of the other end of the jelly roll 2 by the alignment standard stone piece (28SP) of the alignment standard part 28 with excessive force. Since there is no crushing, the accuracy of the secondary battery can be increased. In particular, the unloading jig 22 is formed of a porous ceramic made of Silica material, and the unloading jig 22 has a plurality of holes (through channels: Open Pore) made of micropores that are naturally formed therein. There is no scratch or hole marks on the jelly roll 2 due to the use of silver micropores, and the entire surface of the jelly roll 2 can be uniformly floated, thereby exhibiting a semi-permanent antistatic function by internalizing the antistatic. The entire surface of the jelly roll 2 can be uniformly floated by the unloading jig 22 made of the porous ceramic, thereby exhibiting a semi-permanent antistatic function.

In addition, since the jelly roll is slightly pushed toward the alignment standard by the linear alignment unit while the jelly roll is floating on the unloading jig, the lead of the jelly roll is pushed to align the jelly roll in the longitudinal direction. It prevents damage to the separator, such as squeezing due to excessive pressing of the separator slightly protruding toward the end of the device. By preventing burnout of the separator during the alignment of the jelly roll, it can further contribute to the improvement of the quality of the secondary battery. In particular, only the portion of the linear alignment push piece 26PP protruding from the linear alignment block constituting the linear alignment unit is in contact with the separator protruding from the protruding end of the jelly roll 2 2) is pushed to the alignment reference unit and the jelly roll (2) moves toward the alignment reference unit and after longitudinal alignment is completed, take the jelly roll (2) only on the alignment reference protrusion (28SP) protruding from the alignment reference unit. Since the separator slightly protruding from the end is in contact, it is possible to minimize the contact and pressing of the separator during the alignment process by the longitudinal movement of the jelly roll 2, so that the separator is It is possible to more reliably prevent degradation of the secondary battery due to burnout.
