[0003] The present disclosure relates to a roll transfer device and method. Background Art

[0004] Secondary batteries are batteries that can be reused by discharging to convert chemical energy into electrical energy and charging to convert electrical energy into chemical energy.

[0005] Examples of secondary batteries include nickel - cadmium batteries, nickel - hydrogen batteries, lithium - ion batteries, or lithium - ion polymer batteries.

[0006] Such secondary batteries include a cathode, an anode, an electrolyte, and a separator, and utilize the voltage difference between different cathode and anode materials to store and generate electricity.

[0007] In a method of manufacturing a secondary battery, a method of manufacturing a lithium - ion secondary battery includes: stacking a first separator, an anode plate, a second separator, and a cathode plate; winding them multiple times to form an electrode assembly; sealing the electrode assembly in a case; and injecting an electrolyte into the case.

[0008] In this case, the separator is provided and supplied in the form of a wound roll, and this separator cannot increase its diameter due to material characteristics, so the roll should be frequently replaced during the winding process.

[0009] In this way, in order to replace the roll, when storing the roll wound with the separator, workers classify the rolls according to the type of the corresponding separator and supply the classified rolls to the manufacturing equipment.

[0010] Meanwhile, the position and centering of the roll installed on the manufacturing equipment should be accurately identified so that the defect rate of the product can be reduced. However, workers control the position and centering of the roll by directly checking them, which causes inconvenience and a large amount of working time, and the productivity is reduced because the manufacturing equipment should stop during the corresponding operation.

[0011] In addition, since the roll cannot always be stored in an appropriate position, it is difficult to identify the unique identification code of the material wound on the roll. Summary of the Invention

[0032] Referring to Figures 1 to 3 , a cylinder transfer device 100 according to some embodiments of the present disclosure includes a holding unit 110 and a rotating unit 120.

[0033] The holding units 110 may be arranged to be spaced apart from each other in a first direction D1. In this case, the first direction D1 may be the left-right direction based on Figure 3 .

[0034] The holding unit 110 may support the core part 11 mounted thereon.

[0035] The holding unit 110 may include a support panel 111, holding rollers 112, a driving device, and a detection sensor.

[0036] The support panel 111 may be disposed on the workbench 130. The support panel 111 may move in the second direction D2 when disposed on the workbench 130. In this case, the second direction D2 may be a direction orthogonal to the first direction D1 on a plane based on Figure 2 the plane.

[0037] The holding rollers 112 may be disposed on the support panel 111.

[0038] The holding rollers 112 may be disposed on the support panel 111. The holding rollers 112 may be set to be rotatable. The holding rollers 112 may be provided in pairs to rotatably support the core part 11.

[0039] In other words, the pair of holding rollers 112 is rotatably disposed on the support panel 111 to support the rotation of the core part 11 mounted on the pair of holding rollers 112.

[0040] A driving device is provided to rotate the pair of holding rollers 112. The driving device may be in the shape of a motor. The driving device may be connected to the controller. The driving device may be actuated by the controller to rotate the pair of holding rollers 112.

[0041] The detection sensor may detect the installation of the core part 11. That is, the detection sensor may detect the installation of the core part 11 of the cylinder 10 carried by an automatic guided vehicle (AGV) or a forklift in the cylinder transfer device 100 onto the pair of holding rollers 112. The detection sensor may transmit a signal indicating that the core part 11 has been detected as installed to the controller.

[0042] The detection sensor may be disposed on the support panel 111 or the holding roller 112.

[0043] The holding unit 110 may move on the workbench 130 in the second direction D2. Thus, the cylinder 10 with the unique identification number for winding the material can be transferred to the stacker crane.

[0044] Figure 4 is a schematic partial perspective view showing a cylinder transfer device according to some embodiments of the present disclosure. Figure 5 is a schematic partial perspective view showing a rotating unit of a cylinder transfer device according to some embodiments of the present disclosure.

[0045] Refer to Figures 1 to 6, the rotating units 120 can be disposed in pairs on both sides of the core part 11 along the first direction D1.

[0046] Each of the pair of rotating units 120 can linearly move along the first direction D1. That is, the rotating unit 120 can advance toward the core part 11 or can retreat in the opposite direction.

[0047] The rotating unit 120 can move forward toward the core part 11 to align the position in the first direction D1 along the core part 11.

[0048] The rotating unit 120 can retreat along the first direction D1 in a direction opposite to the core part 11, so that the cylinder 10 in which the unique identification number is fully recognized can move along the second direction D2. When the rotating unit 120 retreats, the controller can move the holding unit pair 112 along the second direction D2 to transfer the cylinder 10 to the stacker crane.

[0049] The rotating unit 120 can linearly move along the first direction D1 and align the position of the cylinder 10 in the first direction D1 in a state where it is inserted into the core part 11 provided on the holding unit 110.

[0050] The rotating unit 120 can include one or more keys 123.

[0051] The key 123 can be coupled to one or more key grooves 12 formed in the core part 11.

[0052] The rotating unit 120 can rotate in a state where it is inserted into the core part 11. The key 123 is coupled to the key groove 12 by the rotation of the rotating unit 120, so that the cylinder 10 can also rotate together.

[0053] The rotating unit 120 can include a rod 121, a pad 122, a first driving member 124, and a second driving member 125.

[0054] The rod 121 can have a shape extending toward the core part 11 along the first direction D1. The rod 121 can be provided to be rotatable.

[0055] The rod 121 can be connected to the first driving member 124. The rod 121 can linearly move along the first direction D1 by the first driving member 124.

[0056] The rod 121 can be connected to the second driving member 125. The shaft included in the rod 121 can be connected to the second driving member 125 through a pulley or the like. The rod 121 can rotate by receiving power from the second driving member 125.

[0057] The pad 122 may be integrally formed with the rod 121. The pad 122 may have a circular shape corresponding to the core portion 11. The pad 122 may be disposed on one side of the rod 121 toward the core portion 11 in the first direction D1.

[0058] The pad 122 may be moved forward in the first direction D1 by the linear movement of the rod 121 and inserted into the core portion 11.

[0059] The pad 122 may be retracted in the first direction D1 by the linear movement of the rod 121 and thus may be separated from the core portion 11.

[0060] The pad 122 may include a key 123.

[0061] One or more keys 123 may be disposed on the outer circumferential surface of the pad 122 in the circumferential direction. The key 123 may be coupled to one or more key grooves 12 by the rotation of the rod 121 in a state where the pad 122 is inserted into the core portion 11.

[0062] In a state where the key 123 is coupled to the key groove 12, the cylinder 10 may be rotated by the rotation of the rod 121.

[0063] The first driving member 124 is arranged to linearly move the rod 121. The first driving member 124 may be connected to a controller.

[0064] For example, the first driving member 124 may have the shape of a cylinder.

[0065] The first driving member 124 may move the rod 121 forward or backward in the first direction D1. When the rod 121 is moved forward or backward by the first driving member 124, the pad 122 may be inserted into the core portion 11 or may be detached from the core portion 11.

[0066] Through the linear movement of the rod 121 by the first driving member 124, the pad 122 may be inserted into the core portion 11 to press the core portion 11, thereby aligning the position of the cylinder 10.

[0067] That is, the rods 121 disposed on both sides of the core portion 11 in the first direction D1 move forward toward the core portion 11 and are inserted into the core portion 11 to press the core portion, so that the position of the cylinder 10 can be aligned in the first direction D1.

[0068] The second driving member 125 is arranged to rotate the rod 121. The second driving member 125 may be connected to a controller.

[0069] For example, the second driving member 125 may have the shape of a motor.

[0070] The second driving member 125 can rotate the rod 121 in a state where the rod 121 is moved forward in the first direction D1 by the first driving member 124 and the pad 122 is inserted into the core portion 11 of the cylinder.

[0071] The second driving member 125 can rotate the rod 121 so that the key 123 provided on the pad 122 inserted into the core portion 11 of the cylinder can be coupled to the key groove 12.

[0072] The second driving member 125 can continuously rotate the rod 121 in a state where the key 123 is coupled to the key groove 12, so that the cylinder 10 can also rotate together.

[0073] The cylinder transfer device 100 according to some embodiments of the present disclosure may further include a barcode reader that identifies a unique identification code of the material wound on the cylinder 10. The barcode reader can be connected to the controller. The barcode reader can be provided on the workbench 130. The barcode reader can be provided above the rotating unit 120.

[0074] The barcode reader can identify the unique identification number at a predetermined position by the rotation of the cylinder 10. That is, in a state where the position of the cylinder 10 is aligned by the linear movement of the rod 121 of the first driving member 124, the cylinder 10 is also rotated by the rotation of the rod 121 of the second driving member 125, so that the barcode reader can constantly identify the unique identification number at a specific position.

[0075] This enables the unique identification code of the material wound on the cylinder 10 to be conveniently identified, even if the cylinder 10 carried and stored in the cylinder transfer device 100 is not properly placed.

[0076] The cylinder transfer device 100 according to some embodiments of the present disclosure may further include a workbench 130.

[0077] The workbenches 130 can be arranged to be spaced apart from each other in the first direction D1. The workbenches 130 can extend in the second direction D2. The holding units 110 can be provided on each of the workbench pairs 130.

[0078] The workbench 130 may include a linear motion (LM) guide provided at a position adjacent to the core portion 11 of the cylinder on its upper surface in the first direction D1.

[0079] The workbench 130 may include an LM motor 131, an LM rail 132, and an LM block 133.

[0080] On the upper surface of the workbench 130, the LM motor 131 can be provided on the side opposite to the rotating unit 120 in the second direction D1. The LM motor 131 can be connected to the controller.

[0081] The LM guide rails 132 can be provided in pairs, connected to the LM motor 11, and extend along the second direction D2.

[0082] The LM blocks 133 can be provided on the LM guide rails 132 and move along the LM guide rails 132 in the second direction D2. The LM blocks 133 can also be provided in pairs and respectively provided on the pair of LM guide rails 132.

[0083] The support panel 120 of the holding unit 110 can be connected to the LM block 133. The cylinder 10 that identifies the unique identification number through the LM block 133 coupled to the support panel 120 can be conveyed to the stacker crane along the second direction D2.

[0084] That is, when the cylinder 10 rotates through the second driving member 125 in a state where the position of the cylinder 10 is aligned by the first driving member 124, when the unique identification number of the cylinder 10 is recognized, the controller actuates the LM motor 131 so that the LM block 133 moves in the second direction D2, thereby enabling the cylinder 10 installed on the holding unit 110 to be conveyed in the second direction D2.

[0085] At this time, in a state where the controller stops the rotation of the rod 121 by stopping the actuation of the second driving member 125 before moving the LM block 133, the controller actuates the first driving member 124 to retract the rod 121 in the first direction D1 toward the opposite side of the cylinder core 11, thereby actuating the LM motor 131 in a state where the pad 122 is separated from the cylinder core 11.

[0086] When the conveyance of the cylinder 10 is completed by the movement of the LM block 133, the controller actuates the LM motor 131 again to move the LM block 133 in the second direction D2 toward the rotating unit 120, so that the LM block 133 can be returned to its original position. Through the return of the LM block 133, the pair of holding units 110 can also be returned to their original positions for subsequent conveyance processes.

[0087] Figure 6 The flowchart shows a cylinder conveyance method according to some embodiments of the present disclosure. Figure 7 The schematic perspective view shows the state where the cylinder core is installed on the holding unit of the cylinder conveyance device to describe the cylinder conveyance method according to some embodiments of the present disclosure. Figure 8 The schematic cross-sectional view shows the state where the cylinder core is installed on the holding unit of the cylinder conveyance device to describe the cylinder conveyance method according to some embodiments of the present disclosure.

[0088] Refer to Figures 6 to 8 , the cylinder core 11 of the cylinder 10 carried and stored by the unmanned transport vehicle or forklift is installed on the upper part of the pair of holding units (S110).

[0089] The cylinder 10 that has been carried and stored is disposed between the holding unit pair 110, and the holding units are arranged to be spaced apart from each other in the first direction D1 to face each other.

[0090] Subsequently, the core part 11 of the cylinder is installed on the upper part of the holding unit pair 110.

[0091] With the core part 11 of the cylinder being installed on the pair of holding rollers 112 of the holding unit 110, the controller actuates the first driving member 124 so that the rod 121 can advance toward the core part 11 in the first direction D1.

[0092] When each rod 121 of the pair of rotating units 120 disposed on both sides of the core part 11 in the first direction D1 continues to move forward, the pad 122 is inserted into the core part 11.

[0093] After the pad 122 is inserted into the core part 11, the rod 121 and the pad 122 of each of the pair of rotating units 120 press the core part 11 through the continuous actuation of the first driving member 124, so that the position of the cylinder 10 is aligned in the first direction D1 (S120).

[0094] When the alignment of the position of the cylinder 10 is completed, the controller stops the actuation of the first driving member 124.

[0095] Subsequently, the controller actuates the second driving member 125 to rotate the rod 121.

[0096] In the state where the pad 122 is inserted into the core part 11, one or more keys 123 that are provided on the pad 122 and rotate integrally with the rod 121 are coupled to one or more key grooves 12.

[0097] In the state where the key 123 is coupled to the key groove 12, the rod 121 of each of the pair of rotating units 120 is continuously rotated, so that the pair of rotating units 120 and the cylinder 10 rotate together (S130).

[0098] In this case, the controller also actuates the driving device of each of the pair of holding units 110 while actuating the second driving member 125 to rotate the pair of holding rollers 112, so as to support the rotation of the core part 11 according to the rotation of the cylinder 10.

[0099] When the core part 11 also rotates as the cylinder 10 continuously rotates and is then set at a specific position, the barcode reader recognizes the unique identification number set at the specific position to identify the material wound on the cylinder 10, and sends an identification signal to the controller (S140).

[0100] Subsequently, the controller stops the actuation of the second driving member 125 and the driving device of the pair of holding units 110.

[0101] The controller actuates the first drive member 124 again, such that the rods 121 of each of the rotary unit pairs 120 are retracted along a first direction D1 toward the opposite side of the core portion 11 of the bobbin, so that the pads 122 are detached from the core portion 11 of the bobbin, and the rods 121 return to their original positions.

[0102] When the return of the rods 121 of the rotary unit pairs 120 is completed, the controller actuates the LM motor 131 such that the LM block 133 moves along a second direction D2.

[0103] When the holding unit pairs 110 move along the second direction D2, the bobbins 10 mounted on the holding unit pairs 110 may also move along the second direction D2 and may then be transferred to the stacker crane (S150).

[0104] When the transfer of the bobbin 10 is completed by the movement of the LM block 133, the controller actuates the LM motor 131 again such that the LM block 133 may return to its original position.

[0105] That is, the LM block 133 may move along the second direction D2 toward the rotary unit 120 such that the holding unit pairs 110 may also return to their original positions for the next transfer process.

[0106] As described above, in the bobbin transfer device and method according to some embodiments of the present invention, the position of the bobbin 10 may be quickly and accurately aligned by the rotary unit 120, and at the same time, the unique identification code of the winding material may be easily identified, thereby improving productivity and reducing the time and labor required for the alignment of the position of the bobbin 10 and the identification of the unique identification code.

[0107] Although embodiments of the present disclosure have been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that the present disclosure may be embodied in other specific forms without departing from the technical spirit and essential features of the present disclosure. Therefore, the above embodiments are considered illustrative rather than restrictive in all respects.
