BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described with reference to embodiments and drawings of the present invention.

The electrode stack system 300a according to the embodiment of the present invention is used in the apparatus 300 for manufacturing an electrode stack shown in FIGS. 3A to 3D.

3A is a schematic perspective view of an electrode stack system according to a first embodiment of the present invention.

Referring to FIG. 3A, an electrode stacking system 300a according to a first embodiment of the present invention includes a separator 330 supplied from a rotating roll 360 onto a stage 302; A first magazine 311 provided on one side of the stage 302 and mounted with a plurality of first electrodes 310; A second magazine 321 spaced apart from the first magazine 311 and provided on one side of the stage 302, on which a plurality of second electrodes 320 are mounted; It is provided on the first magazine 311 and the second magazine 321, the plurality of first electrode 310 and the plurality of second electrode 320 sequentially on the separator 330. An articulated robot 314 for supplying; The plurality of first electrodes 310 are provided between the stage 302 and the first magazine 311, and the plurality of first electrodes 310 are transferred onto the separator 330 by the articulated robot 314. A first alignment camera 380a1 for prealigning the first electrode 310; And a plurality of second electrodes 320 provided between the stage 302 and the second magazine 321 while being transferred onto the separator 330 by the articulated robot 314. And a second align camera 380a2 for pre-aligning the second electrode 320. Here, the plurality of first electrodes 310 and the plurality of second electrodes 320 may be cathode electrodes and anode electrodes, or anode electrodes and cathode electrodes, respectively. In addition, the first and second alignment cameras 380a1 and 380a2 may be implemented as vision cameras, respectively, and the articulated robot 314 may be, for example, a six-axis vertical articulated robot widely used for industrial purposes. It can be implemented as.

Hereinafter, a detailed configuration and operation of the electrode stacking system 300a according to the first embodiment of the present invention will be described in detail.

Referring again to FIG. 3A, in the electrode stacking system 300a according to the first embodiment of the present invention, the pair of fingers 350 provided with the separator 330 from the rotary roll 360 under the rotary roll 360 are provided. Is supplied onto the stage 302. In this case, the supply of the separator 330 may be performed by moving the stage 302 from the A1 position to the A2 position while the rotary roll 360 and the pair of fingers 350 are fixed (hereinafter, referred to as a "stage movement method"). ").

The separator 330 is then clamped on the stage 302 by a pair of first and second clamping devices 304a1, 304a2. Thereafter, one of the plurality of first electrodes 310 in which the articulated robot 314 is mounted on the first magazine 311 (hereinafter, referred to as "first electrode 310"). Pick up and transport it onto the separator 330. For this purpose, the articulated robot 314 is provided with a pickup member 314a. The pickup member 314a may, for example, adsorb and transport the first electrode 310 by a vacuum suction method. In this case, the first alignment camera 380a1 is provided on a path through which the first electrode 310 is transferred onto the separator 330 by the articulated robot 314. Therefore, the first alignment camera 380a1 captures the first image of the first electrode 310 in a non-contact manner while the first electrode 310 is transferred. The first image is transmitted to a controller (not shown) connected to the first alignment camera 380a1 and the second alignment camera 380a2 in a wired or wireless manner, respectively. Here, the controller may be mounted on the articulated robot 314 or provided separately from the articulated robot 314. When the controller is provided separately from the articulated robot 314, the controller is connected to the articulated robot 314 in a wired or wireless manner. Such a controller may be implemented as a personal computer (PC) or a microprocessor.

Meanwhile, the controller receives the first image and checks first image information (eg, X, Y, and coordinate values) corresponding to the first image. Thereafter, the controller compares the first coordinate information (eg, X, Y, and coordinate values) on the separator 330 to which the first electrode 310 is to be transferred to the difference value (that is, the first alignment). Coordinate value). In this case, the first coordinate information on the separator 330 to which the first electrode 310 is to be transferred is previously stored in the controller. Thereafter, the controller controls the articulated robot 314 to transfer the first electrode 310 by the first alignment coordinate value. Therefore, the first electrode 310 is aligned in advance while being transported onto the separator 330 by the first alignment camera 380a1 and the controller, and is transferred separately on the separator 330 and then aligned separately. This is unnecessary.

When the first electrode 310 is transferred on the separator 330 in the above-described manner, the articulated robot 314 moves to the second magazine 321. At the same time, the stage 302 returns from the A2 position to the A1 position. Accordingly, the separator 330 covers the upper portion of the first electrode 310. Thereafter, after the pair of first and second clamping devices 304a1 and 304a2 release the clamping state of the separator 330, the upper part of the separator 330 covering the upper part of the first electrode 310 is again clamped. Thus, the separator 330 remains fixed on the stage 302. Thereafter, the articulated robot 314 uses one of the plurality of second electrodes 320 mounted on the second magazine 321 using the pickup member 314a (hereinafter referred to as “second”). Electrode 320 ”) is picked up and transported onto the separator 330. In this case, the second alignment camera 380a2 is provided on a path through which the second electrode 310 is transferred onto the separator 330 by the articulated robot 314. Accordingly, the second alignment camera 380a2 captures the second image of the second electrode 320 in a non-contact manner while the second electrode 320 is being transferred. The second image is sent to the controller. The controller receives the second image and checks second support information (eg, X, Y, and coordinate values) corresponding to the second image. The controller then compares the second coordinate information (eg, X, Y, and coordinate values) on the separator 330 to which the second electrode 320 is to be transferred to the difference value (ie, the second alignment). Coordinate value). In this case, the second coordinate information on the separator 330 to which the second electrode 320 is to be transferred is also previously stored in the controller. Thereafter, the controller controls the articulated robot 314 to transfer the second electrode 320 by the second alignment coordinate value. Accordingly, the second electrode 320 is aligned in advance while being transferred onto the separator 330 by the second alignment camera 380a2 and the controller, and is transferred separately on the separator 330 before performing a separate alignment operation. This is unnecessary.

In the first embodiment of the present invention illustrated in FIG. 3A described above, the supply of the separator 330 is exemplarily illustrated as a stage moving method. However, those skilled in the art will fully appreciate that the supply of separator 330 can be accomplished by moving a pair of fingers 350 on stage 302 with stage 302 fixed at the A1 or A2 position. (Hereinafter referred to as "finger movement").

In addition, in the first embodiment of the present invention, the plurality of first electrodes 310 and the plurality of second electrodes 320 are one magazine in which the first electrode 310 and the second electrode 320 are sequentially stacked. Only the first magazine 311 or the second magazine 321 may be used. For example, when the first magazine 311 in which the plurality of first electrodes 310 and the plurality of second electrodes 320 are sequentially stacked is used, the articulated robot 314 may be configured as, for example, a first magazine ( The first electrode 310 is picked up from 311, supplied to the separator 330, and returned to the first magazine 311. At the same time, the separator 330 covers the upper portion of the first electrode 310 supplied by moving in a stage movement method or a finger movement method. Thereafter, the articulated robot 314 picks up the second electrode 320 from the first magazine 311, supplies it to the separator 330, and returns to the first magazine 311. At the same time, the separator 330 covers the upper portion of the second electrode 310 supplied by moving in a stage movement method or a finger movement method. Therefore, by repeating the above-described operation, the articulated robot 314 sequentially picks up the first electrode 320 and the second electrode 320 from the first magazine 311 and supplies them to the separator 330, And repeatedly performing cycles of sequentially covering the first electrode 320 and the second electrode 320 supplied with the separator 330 to the plurality of first electrodes 310 and the plurality of second electrodes 320. It may be supplied and stacked on the separator 330.

In addition, the first to fourth alignment cameras 380a1, 380a2, 380b1, and 380b2 may be implemented as vision cameras, respectively. It can be implemented with a vertical articulated robot.

Hereinafter, a detailed configuration and operation of the electrode stacking system 300a according to the second embodiment of the present invention will be described in detail.

Referring again to FIGS. 3B to 3D, in the electrode stacking system 300a according to the second embodiment of the present invention, the first separator 330a is moved from the first rotation roll 360a to the first rotation roll 360a. It is supplied on the first stage 302a through a pair of first fingers 350a provided in the lower portion, and the second separator 330b is lowered from the second rotating roll 360b from the second rotating roll 360b. Supplied to the second stage 302b through a pair of second fingers 350b provided at. In this case, the supply of the first separator 330a is performed by moving the first stage 302a from the A1 position to the A2 position while the first rotary roll 360a and the pair of first fingers 350a are fixed. The second separator 330b may be supplied by moving the second stage 302b from the B1 position to the B2 position while the second rotary roll 360b and the pair of second fingers 350b are fixed. (Stage movement method).

Thereafter, the first separator 330a is clamped on the first stage 302a by the pair of first and second clamping devices 304a1 and 304a2 to maintain a fixed state, and the pair of third and third The second separator 330b is clamped on the second stage 302b by the four clamping devices 304b1 and 304b2 to maintain a fixed state. Thereafter, the articulated robot 314 picks up the first electrode 310 mounted on the first magazine 311 using the pickup member 314a and transfers the first electrode 310 onto the first separator 330a. In this case, the first alignment camera 380a1 captures the first image of the first electrode 310 in a non-contact manner while the first electrode 310 is transferred. The first image is transmitted to a controller (not shown), and the controller receives the first image and checks first image information (eg, X, Y, and coordinate values) corresponding to the first image. Thereafter, the controller compares the first coordinate information (eg, X, Y, and coordinate values) on the first separator 330a to which the first electrode 310 is to be transferred to the difference value (ie, the first value). Calculate the alignment coordinate value). In this case, the first coordinate information on the first separator 330a to which the first electrode 310 is to be transferred is previously stored in the controller. Thereafter, the controller controls the articulated robot 314 to transfer the first electrode 310 by the first alignment coordinate value. Therefore, the first electrode 310 is aligned in advance while being transferred onto the first separator 330a by the first alignment camera 380a1 and the controller, and then transferred to the first separator 330a and then separately. Alignment is unnecessary.

When the first electrode 310 is transferred on the first separator 330a in the manner described above, the articulated robot 314 moves to the second magazine 321. At the same time, the first stage 302 moves from the A1 position to the A2 position (see FIG. 3C). Accordingly, the first separator 330a covers the upper portion of the first electrode 310. Thereafter, after the pair of first and second clamping devices 304a1 and 304a2 release the clamping state of the first separator 330a, the first separator 330a covering the upper portion of the first electrode 310 again. The first separator 330a is fixed on the first stage 302a by clamping an upper portion of the first separator 330a. Thereafter, the articulated robot 314 picks up the second electrode 320 mounted on the second magazine 321 using the pickup member 314a and transfers the second electrode 320 onto the first separator 330a. At this time, the second alignment camera 380a2 captures the second image of the second electrode 320 in a non-contact manner while the second electrode 320 is being transferred. The second image is sent to the controller. The controller receives the second image and checks second image information (eg, X, Y, and coordinate values) corresponding to the second image. Thereafter, the controller compares the second coordinate information (eg, X, Y, and coordinate values) on the first separator 330a to which the second electrode 320 should be transferred to the difference value (ie, the second value). Calculate the alignment coordinate value). In this case, the second coordinate information on the first separator 330a to which the second electrode 320 is to be transferred is also previously stored in the controller. Thereafter, the controller controls the articulated robot 314 to transfer the second electrode 320 by the second alignment coordinate value. Therefore, the second electrode 320 is aligned in advance while being transferred onto the first separator 330a by the second alignment camera 380a2 and the controller, and then transferred to the first separator 330a and then separately. Alignment is unnecessary.

The articulated robot 314 then moves back to the second magazine 321. At the same time, the first stage 302 moves from the A2 position to the A1 position (see FIG. 3C). Accordingly, the first separator 330a covers the upper portion of the second electrode 320. Thereafter, after the pair of first and second clamping devices 304a1 and 304a2 release the clamping state of the first separator 330a, the first separator 330a covering the upper part of the second electrode 310 again. The first separator 330a is fixed on the first stage 302a by clamping an upper portion of the first separator 330a.

Thereafter, the articulated robot 314 picks up the second electrode 320 mounted on the second magazine 321 using the pickup member 314a, and the second stage 302b of the second stage 302b positioned at B1. It feeds on 2 separator 330b. At this time, the fourth alignment camera 380b2 captures the fourth image of the second electrode 320 in a non-contact manner while the second electrode 320 is being transferred. The fourth image is sent to the controller. The controller receives the fourth image and checks fourth image information (eg, X, Y, and coordinate values) corresponding to the fourth image. Thereafter, the controller compares the fourth coordinate information (eg, X, Y, and coordinate values) on the second separator 330b to which the second electrode 320 should be transferred to the difference value (ie, the fourth value). Calculate the alignment coordinate value). In this case, the fourth coordinate information on the second separator 330a to which the second electrode 320 is to be transferred is also previously stored in the controller. Thereafter, the controller controls the articulated robot 314 to transfer the second electrode 320 by the fourth alignment coordinate value. Therefore, the second electrode 320 is aligned in advance while being transferred onto the second separator 330b by the fourth alignment camera 380b2 and the controller, and is transferred to the second separator 330b and then separated. Alignment is unnecessary.

When the second electrode 320 is transferred on the second separator 330b in the manner described above, the articulated robot 314 moves to the first magazine 331. At the same time, the second stage 302 moves from the B1 position to the B2 position (see FIG. 3C). Accordingly, the second separator 330b covers the upper portion of the second electrode 320. Thereafter, after the pair of third and fourth clamping devices 304b1 and 304b2 release the clamping state of the second separator 330b, the second separator 330b covering the upper part of the second electrode 320 again. The second separator 330b is fixed on the second stage 302b by clamping an upper portion of the upper surface of the second stage 302b. Thereafter, the articulated robot 314 picks up the first electrode 310 mounted on the first magazine 311 using the pickup member 314a and transfers it onto the second separator 330b. At this time, the third alignment camera 380b1 captures the third image of the first electrode 310 in a non-contact manner while the first electrode 310 is transferred. The third image is sent to the controller. The controller receives the third image and checks third image information (eg, X, Y, and coordinate values) corresponding to the third image. Thereafter, the controller compares the third coordinate information (eg, X, Y, and coordinate values) on the second separator 330b to which the first electrode 310 is to be transferred to the difference value (that is, the third value). Calculate the alignment coordinate value). In this case, the third coordinate information on the second separator 330b to which the first electrode 310 is to be transferred is also previously stored in the controller. Thereafter, the controller controls the articulated robot 314 to transfer the first electrode 310 by the third alignment coordinate value. Therefore, the first electrode 310 is aligned in advance while being transferred onto the second separator 330b by the third alignment camera 380b1 and the controller, and is transferred to the second separator 330b and then separated. Alignment is unnecessary.

As described above, the articulated robot 314 sequentially supplies the first electrode 310 and the second electrode 320 on the first separator 330a, and then the second electrode 320 and the first electrode ( By sequentially supplying 310 onto the second separator 330b, the electrode stack for forming one electrode body on the first stage 302a and the electrode for forming another electrode body on the second stage 302b. One cycle of lamination is completed. Therefore, in the electrode stacking system 300a according to the second embodiment of the present invention, the electrode stack for forming two electrode bodies is possible by repeating the above-described operation. In this case, since only one articulated robot 314 is used, the number of components of the electrode stacking system 300a is further reduced compared to the first embodiment, and an advantage of increasing space efficiency is achieved.

For example, when the first magazine 311 sequentially stacked in the order of repeating the first electrode 310, the second electrode 320, the second electrode 320, and the first electrode 310 is used. The articulated robot 314 sequentially picks up the first electrode 310 and the second electrode 320 and supplies the first electrode 310 and the first electrode 330a to which the first separator 330a is supplied.
