Description
Technical Field

In general, a secondary battery is a battery that can be repeatedly used through a discharge process for converting chemical energy into electric energy and a reverse charge process, and its kinds include a nickel-cadmium (Ni-Cd) battery, a nickel-metal hydride (Ni-MH) battery, a lithium metal battery, a lithium Ion (Ni-Ion) battery, a polymer lithium Ion battery, and the like.
The secondary battery is composed of an anode, a cathode, an electrolyte, and a separation membrane, and stores and generates electricity using a voltage difference between anode and cathode materials different from each other. Here, the discharge is to move electrons from a cathode having a high voltage to an anode having a low voltage (to generate electricity according to a voltage difference between the anodes), and the charge is to move electrons from the anode to the cathode again, and at this time, the anode material receives the electrons and lithium ions and returns to the original metal oxide. That is, the secondary battery generates a charge current as metal atoms pass through the separation membrane and move from the anode to the cathode when charged, and conversely, generates a discharge current as metal atoms move from the cathode to the anode when discharged.
On the other hand, such a secondary battery may be manufactured in a winding manner and a stacking manner in which anode plates and cathode plates cut to a predetermined size are alternately stacked to manufacture an electrode assembly. It is disclosed in korean patent No. 1421847 (published: 2012.05.31).
However, such a prior art has a problem in that the size of the electrode plate is changed by changing the model of the manufacturing machine, but the same stacking operation is performed, resulting in a decrease in the manufacturing efficiency.

Detailed Description
Hereinafter, a multi-cell secondary battery stacking apparatus and a control method thereof according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description of the embodiments, the names of the respective components may be named by other names in the technical field. However, when there are functional similarities and similarities, even if the modified embodiments are adopted, they may be regarded as equivalent configurations. In addition, reference numerals attached to the respective constituent elements are described for convenience of description. However, the illustration on the drawings in which these reference numerals are described does not limit the respective constituent elements to the scope within the drawings. Similarly, even if the components on the drawings are adopted by the partially modified embodiments, when there is functional similarity and identity, they can be regarded as equivalent components. In addition, when it is considered that the constituent elements should be included in view of the level of those skilled in the art, the description thereof will be omitted.
Fig. 1 is a drawing illustrating the concept of secondary battery stacking. As shown, the electrode assembly 1000 (or jellyroll) is produced by stacking plates 2000 bounded by a separation membrane 5000, formed by having anode plate 3000 on one side and cathode plate 4000 on the other side. For example, the secondary battery electrode plate stacking apparatus can produce an electrode assembly having several tens to several hundreds of layers by repeating the operation of placing the anode plate 3000 and covering the separation membrane 5000, and then placing the cathode plate 4000 and covering the separation membrane 5000.
Fig. 2 is a perspective view illustrating an electrode assembly 1000 formed in different sizes according to different models. The present invention is capable of producing a variety of models of electrode assemblies 1000 as shown in fig. 2. Each model may be formed with a size of the plate 2000, particularly, an area in a plane direction being different. The secondary battery stacking apparatus of the present invention corresponds to the size of the electrode plate 2000 according to the model change of the electrode assembly, and thus can maximize the production efficiency.
On the other hand, although not shown, the secondary battery stacking apparatus may include an electrode plate taking and placing device, a vision inspection device, a stacking plate, a loading position inspection unit, and a separation film supply device independent of a transport path of the electrode plates, based on the order of transporting the electrode plates, and may further include a tension and corner position control device of the separation film.
The stacked plate 600 for stacking the plates will be described in detail below with reference to fig. 3 to 7.
Fig. 3 is a partial perspective view of an area including stacked plates 600. As shown in the drawing, the multi-unit type secondary battery stacking apparatus of the present invention checks whether there is an abnormality in the plates when there are anode plates 3000 and cathode plates 4000 transferred, transfers to the N/G tray 610 when there is an abnormality, and transfers to the stack plate 600 and stacks when there is no abnormality. On the premise that most of the plates are not abnormal, when the plates are transferred from the buffer plates 301 and 302 to the alignment devices 401 and 402 and from the alignment devices 401 and 402 to the stacking plate 600, the manipulator can pick up two plates and move the plates at two positions at the same time, so that the production efficiency is improved.
The secondary battery stacking apparatus is formed in a symmetrical manner so that the anode plate 3000 and the cathode plate 4000 can be inspected and transferred, respectively, with only the stacked plate 600 in which the electrode plate 2000 is finally stacked together with the separation membrane 5000 being formed as a single structure. The stacking plate 600 shuttles to the conveying line of the anode plate 3000 and the conveying line of the cathode plate 4000 and stacks the anode plate 3000 and the cathode plate 4000.
Although not shown in advance, the anode plate is moved in the x direction from the magazine 200 by the pick-and-place device shown in fig. 3 and is mounted on the first buffer plate 301, and is mounted on the upper surface of the first alignment device 401 by a robot. In addition, the cathode plate is mounted to the second buffer plate 302 and is mounted to the upper surface of the second alignment device 402 by a robot. Then, the inspection is performed by a visual inspection device, and when the electrode plate is defective, P is transmittedNTo the N/G tray 610 at the rear side, when a normal plate, passesThe robot moves to the stack plate 600 and stacks them. Even if the plate is normal, the alignment devices 401 and 402 can be driven when the alignment position or posture is required. Among them, UVW alignment apparatuses may be used as an example of the alignment apparatuses 401 and 402. On the other hand, the conveyance paths of the anode plate 3000 and the cathode plate 4000 are formed in parallel sections parallel to each other in the y direction from the N/G tray 610 to the stacked plate 600, and the stacked plate 600 is formed to be reciprocally moved in a direction perpendicular to the parallel sections, that is, in the x direction and stacked.
Fig. 4 is a top view of fig. 3. As shown, an anode plate transport path P1 and a cathode plate transport path P2 are labeled. The plate transport path may be defined as the area through which the plate passes as it moves. The secondary battery stacking apparatus maintains a set position when a model of the secondary battery is determined, and can adjust a pitch when the model is changed.
Fig. 5 is a diagram illustrating a pitch adjustment concept with respect to a plate transfer line. As shown in the drawing, when the model is changed, for example, when the size of the pole plate becomes small, the x-direction position of each device can be adjusted to increase the stacking speed. On the other hand, when the stacking plate 600 is set to the shuttle position as the same regardless of the size of the pole plate, the stacking speed does not change even if the size of the pole plate becomes small. However, in the present embodiment, as the size of the electrode plate becomes smaller, the reciprocating distance of the stacked plates is reduced, so that the stacking speed can be increased. For this, the positions of the robot, the aligning devices 401, 402, and the buffer plates 301, 302 are adjusted so as to maintain the interval between the anode plate conveying line P1 and the cathode plate conveying line P2 constant. Specifically, the stack plate 600 can maintain the same spacing between the anode plate loaded at the first position Q1 and the cathode plate loaded at the second position Q2 to increase the stacking speed.
Fig. 6 is a diagram showing the concept of round trip section setting of the stacked board 600. Explaining again the spacing between the anode plate transport line P1 and the cathode plate transport line P2, fig. 6 (a) to 6 (c) all show examples of moving plates of different sizes, while keeping the spacing L between the anode plate transport line P1 and the cathode plate transport line P2 constant. That is, the x-direction pitches between the corners of the anode plate 3000 and the cathode plate 4000 facing each other are all kept the same. Accordingly, the distances d1, d2, d3 between the first position Q1 of the anode plate transmission line and the second position Q2 of the cathode plate transmission line become closer to each other as the size of the electrode plate becomes smaller. On the other hand, the first and second positions Q1, Q2 of the shuttle section of the stacked plate 600 are adjusted to be aligned with the x-coordinate corresponding to the center axis of the anode plate transport line and the x-coordinate corresponding to the center axis of the cathode plate transport line, respectively. As a result, the smaller the size of the electrode plate, the shorter the reciprocating interval of the stacked plate 600 (d1 > d2 > d 3). On the other hand, although not shown, the control unit can update the plate installation size in accordance with an input signal for changing the plate model of the user, and can update the first position Q1 and the second position Q2, which are the reciprocating positions of the stacked plate 600, in accordance with the plate installation size.
Fig. 7 is an operation state diagram showing an operation when the shuttle section of the stack board 600 is adjusted.
As shown, stacked plate 600 continuously receives separation membrane 5000 and stacks anode plate 3000 in a first position and cathode plate 4000 in a second position. As shown in fig. 7 (b), when the size of the electrode plate is reduced, the position of the holder for holding the electrode assembly 1000 in the stacking plate 600 can be reduced corresponding to the electrode plate. In addition, as described above, when the distance between the anode plate 3000 and the cathode plate 4000 (the pitch between the observed corners) is set to be the same and the plates are set in a small size, the round trip distance d2 of the stacked plate 600 can be reduced to shorten the stacking time.
As a result, the multi-unit type secondary battery stacking apparatus of the present invention can be configured such that the reciprocating distance of the stacking plate 600 is shorter as the size of the stacked electrode plate is smaller, and the production speed can be improved according to the model change.
A method for controlling a multi-cell secondary battery stacking apparatus according to another embodiment of the present invention will be described below with reference to fig. 8.
Fig. 8 is a flowchart of a control method of the multi-type secondary battery manufacturing apparatus capable of adjusting the position when the receiver type is changed.
As shown in the drawing, the method for controlling a multi-unit type secondary battery manufacturing apparatus according to the present invention includes a step S100 of receiving an input signal for changing the type of a plate and a step S200 of changing a plate transport path.
Step S100 of receiving an input signal for changing the model of the electrode plate is a step of receiving an input signal for secondary batteries having different stack sizes from a user. The user can select the type of plate to be produced from a preset table.
The plate transport path changing step S200 corresponds to a step of changing the positions of the respective elements of the secondary battery stacking apparatus according to the change in the size of the plates so as to maximize the production efficiency. The electrode plate conveying path changing step can be controlled so that the distance between the paths of the conveyed anode plate and cathode plate can be kept constant even if the size of the electrode plate changes. That is, as the size of the cathode plate becomes smaller, the distance between the center point of the anode plate and the center point of the cathode plate on the conveyance path becomes smaller, but the spacing between the corner portions facing each other at the adjacent positions can be kept constant. Therefore, the smaller the electrode plate, the shorter the reciprocating position of the stacked plate 600, and the stacking efficiency can be improved. The electrode plate transfer path changing step includes a stacking plate reciprocating position adjusting step S210, a loading position inspecting part pitch adjusting step S220, a robot pitch adjusting step S230, an alignment device pitch adjusting step S240, and a vision inspecting part inspection position adjusting step S250.
As described above, the reciprocating position adjusting step S210 of the stack plate corresponds to a step of adjusting the reciprocating position of the stack plate to be shorter as the size of the pole plate becomes smaller. Wherein even if the reciprocating position of the stacking plate 600 becomes short, the position can be adjusted to maintain the interval between the plates constant between each other at the first position where the anode plate is transferred and loaded and the second position where the cathode plate is loaded.
The loading position inspection part pitch adjustment step S220 is a step of adjusting the pitch between the loading position inspection parts 700 corresponding to the reciprocating position of the stack plate 600. The loading position inspecting parts 700 can photograph the upper surface of the stack plate 600 from the upper side of the stack plate 600, and therefore, the pitch between the loading position inspecting parts 700 can be adjusted according to the pitch between the shuttle positions of the stack plate 600.
The robot-spacing adjusting step S230 is a step of adjusting the spacing between the robot for transferring the anode plate and the robot for transferring the cathode plate. In practice, the transfer path of the plates is determined by the robot, and thus, the interval between the robots is determined according to the preset interval between the plates.
The aligning device pitch adjusting step S240 is a step of adjusting the positions of the aligning devices 401, 402, which adjust the aligning devices 401, 402 to correct position errors and attitude errors before transferring the electrode plates to the stacking plate 600 and loading. The adjustment of the pitch between the alignment devices 401 and 402 can be performed in correspondence with the adjustment of the shuttle position of the stacker plate 600 and the pitch between the robots.
On the other hand, in the plate transport path changing step S200, an example in which the steps (S210 to S250) are sequentially performed will be described as an example, but the steps may be independently performed regardless of this.
The inspection position adjusting step S250 of the vision inspection portion corresponds to a step of adjusting the vision inspection area 710 according to the size of the electrode plate. As described above, the anode plate and the cathode plate can maintain the same alignment position of the corners facing each other even if the model is changed. As a result, as the size of the plate is changed, the positions of the corner portions spaced apart from each other in the plates on both sides are changed, and thus, it is possible to perform the alignment by adjusting the positions of the second alignment camera and the defect detection camera for photographing the corners on the outer periphery side.
In the control method of the multi-module secondary battery manufacturing apparatus described above, as the size of the electrode plate becomes smaller, the reciprocating distance of the stacked plates becomes shorter, and the stacking time can be shortened. To this end, the spacing between the conveyance paths of the anode plates and the conveyance paths of the cathode plates is adjusted to convey the plates in an optimized path and to inspect and align them before loading them into the stack.
