Description

태양전지 셀의 태빙 장치Tabbing device of solar cell
본 발명은 태양전지 셀의 태빙 장치에 관한 것으로, 보다 상세하게는 태양전지 셀의 스트링을 제작하는 태양전지 셀의 태빙 장치에 관한 것이다.The present invention relates to a tabbing device for a solar cell, and more particularly to a tabbing device for a solar cell for producing a string of the solar cell.
일반적으로 태양전지셀(solar cell)은 태양에너지를 전기에너지로 변환시켜주는 반도체소자이다. 태양전지셀에는 실리콘, 갈륨비소, 카드뮴 텔루르, 황화카드뮴, 인듐인 또는 이를 복합한 재료들이 사용된다.In general, a solar cell is a semiconductor device that converts solar energy into electrical energy. Solar cells are made of silicon, gallium arsenide, cadmium tellurium, cadmium sulfide, indium phosphorus or a combination thereof.
태양전지셀은 최대 전압이 0.5V 밖에 발생하지 않아 기전력이 작기 때문에, 다수의 태양전지셀을 직렬로 연결하여 적정 기전력을 갖는 태양전지모듈(Photovoltaic Module)로 사용된다.Since a solar cell has a small maximum electromotive force since only a maximum voltage of 0.5V is generated, it is used as a photovoltaic module having a suitable electromotive force by connecting a plurality of solar cells in series.
여기서, 통상의 태양전지셀에는 다수의 전극라인이 형성되는데, 리본 형태의 금속전극을 접합하여 전극라인이 상호 전기적으로 연결되도록 한다.Here, a plurality of electrode lines are formed in a typical solar cell, and the electrode lines are electrically connected to each other by bonding a metal electrode of a ribbon shape.
이때, 금속전극으로는 납이 피복된 도체 리본이 통상적으로 사용되며, 각 태양전지셀이 직렬로 연결되도록 각 태양전지셀의 전면과 후면에 리본이 엇갈리도록 접합한다. 이러한 공정을 태빙 공정(tabbing process)이라 한다.In this case, a lead-coated conductor ribbon is commonly used as the metal electrode, and the ribbon is bonded to the front and rear of each solar cell so that each solar cell is connected in series. This process is called a tabbing process.
즉, 태빙 공정은 복수 개의 전도성 스트립(conductive strip)을 태양전지셀의 상부와 하부에 각각 이송시켜 접합시키는데, 그리퍼(gripper)가 전도성 스트립을 그립한 후 이송시키는 과정에서 전도성 스트립이 그리퍼에서 이탈되는 경우가 종종 발생하게 되었다.That is, in the tabbing process, a plurality of conductive strips are transferred to and bonded to the upper and lower portions of the solar cell, respectively, in which the conductive strip is separated from the gripper during the gripper grips and transfers the conductive strip. Cases often occurred.
그러나, 종래에는, EL(Electro luminance) 검사 전까지, 전도성 스트립이 이탈되었는지 여부를 확인할 수 없었고, 전도성 스트립 이탈 제품 발생시부터 검사설비까지의 구간에 속하는 제품 및 공정에 악영향을 초래하게 되는 문제점이 있었다.However, conventionally, it was not possible to confirm whether the conductive strip was detached until the EL (Electro luminance) inspection, and there was a problem that adversely affects products and processes belonging to the section from the occurrence of the conductive strip leaving product to the inspection facility.
본 발명의 배경기술은 대한민국 공개특허공보 제2013-0011677호에 개시되어 있다.Background of the present invention is disclosed in Korean Unexamined Patent Publication No. 2013-0011677.
본 발명은 전술한 문제점을 해결하기 위해 창안된 것으로서, 본 발명은, 그리퍼로부터 전도성 스트립 각각으로 검지 신호를 전달하고 전도성 스트립 각각을 통해 검지 신호가 전달되는지 여부를 판단하여, 판단 결과에 따라 태양전지 셀의 스트링(solar cell string)의 제작 과정에서의 결함 여부를 판정하는 태양전지 셀의 태빙 장치를 제공한다. 보다 구체적으로는, 본 발명은, 그리퍼를 통해 전도성 스트립을 공급하는 과정에서 전도성 스트립이 정확하게 태양전지 셀에 공급되는지 여부를 판정하는 태양전지 셀의 태빙 장치를 제공한다.The present invention has been made to solve the above-described problems, the present invention, by transmitting a detection signal from the gripper to each of the conductive strips and determines whether the detection signal is transmitted through each of the conductive strips, the solar cell according to the determination result Provided is a tabbing device for a solar cell that determines whether a defect occurs in a manufacturing process of a solar cell string.

Defective rate is reduced.

따라서, 제어부(90)는 각 전도성 스트립(1)별로 검지신호가 전달되는지 여부를 토대로 전도성 스트립(1) 각각이 그리퍼(10)에 정상적으로 그립되었는지 여부를 판단한다. 제어부(90)는 전도성 스트립(1) 중 검지신호가 수신된 전도성 스트립(1)에 대해서는 정상적으로 그립된 것으로 판정하고, 검지신호가 수신되지않은 전도성 스트립(1)에 대해서는 비정상적으로 그립된 것으로 판정한다. 여기서, 전도성 스트립(1)이 비정상적으로 그립된 경우에는, 그리퍼(10)가 전도성 스트립(1)을 그립하지 않았거나, 또는 전도성 스트립(1)이 잘못 그립되어 검지신호가 전달되지 않는 경우가 모두 포함될 수 있다. 이어서, 제어부(90)는 전도성 스트립(1)이 정상적으로 그립되었는지 여부를 출력부(80)를 통해 출력한다.Therefore, the controller 90 determines whether each of the conductive strips 1 is normally gripped by the gripper 10 based on whether the detection signal is transmitted to each conductive strip 1. The control unit 90 determines that the conductive strip 1 of the conductive strip 1 has been normally gripped with respect to the conductive strip 1 that has received the detection signal, and determines that the grip has been abnormally gripped with respect to the conductive strip 1 with no detection signal received. . Here, when the conductive strip 1 is abnormally gripped, the gripper 10 does not grip the conductive strip 1 or the conductive strip 1 is incorrectly gripped so that the detection signal is not transmitted. May be included. Subsequently, the controller 90 outputs through the output unit 80 whether the conductive strip 1 is normally gripped.
상기한 바와 같이, 제어부(90)는 전도성 스트립(1)이 정상적으로 그립되었는지 여부를, 각 전도성 스트립(1)을 통해 전달되는 검지신호를 수신하는지의 여부에 의해 판단한다. 즉, 본 실시예에 의하면, 전도성 스트립(1)이 정상적으로 그립되었는지 여부는, 검지신호의 ON 및 OFF에 의해 판정된다. 따라서, 간단한 구성에 의해 전도성 스트립(1)이 정상적으로 그립되었는지 여부가 판정될뿐만 아니라, 이러한 판정은 전도성 스트립(1)의 표면에 존재하는 플럭스(flux) 또는 이물질에 의해 영향을 받지 않는다.As described above, the controller 90 determines whether the conductive strip 1 is gripped normally by whether or not a detection signal transmitted through each conductive strip 1 is received. That is, according to this embodiment, whether the conductive strip 1 is normally gripped is determined by the ON and OFF of the detection signal. Thus, in addition to determining whether the conductive strip 1 is normally gripped by a simple configuration, this determination is not affected by the flux or foreign matter present on the surface of the conductive strip 1.
한편, 상기한 바와 같이 그리퍼(10)가 전도성 스트립(1)을 그립한후에는, 도4에 도시된 바와 같이 제어부(90)는 그리퍼 이동부(20)를 제어하여 그리퍼(10)를 기 설정된 설정 위치까지 이동시킨다. 이와 같이 그리퍼 이동부(20)를 통해 그리퍼(10)를 이동시키는 과정에서 그리퍼(10)에서 전도성 스트립(1)이 이탈될 수 있다.On the other hand, after the gripper 10 grips the conductive strip 1 as described above, as shown in FIG. 4, the controller 90 controls the gripper moving unit 20 to set the gripper 10 in a preset manner. Move to position As such, the conductive strip 1 may be separated from the gripper 10 in the process of moving the gripper 10 through the gripper moving unit 20.
그리퍼(10)가 전도성 스트립(1)을 그립한 상태에서는, 검지신호 전송부(30)는 검지신호를 피딩 클램프(11)를 통해 지속적으로 전달하고, 검지신호 수신부(50)는 전도성 스트립(1)으로부터 고정 클램프(42)를 통해 검지신호를 수신한다.In the state where the gripper 10 grips the conductive strip 1, the detection signal transmitter 30 continuously transmits the detection signal through the feeding clamp 11, and the detection signal receiver 50 is connected to the conductive strip 1. ), A detection signal is received through the fixed clamp 42.
제어부(90)는 검지신호 수신부(50)를 통해 전도성 스트립(1) 각각으로부터 검지신호가 수신되는지 여부를 판단하여 판단 결과에 따라 그리퍼(10)로부터 전도성 스트립(1) 각각의 이탈 여부를 판정한다.The controller 90 determines whether a detection signal is received from each of the conductive strips 1 through the detection signal receiving unit 50, and determines whether the conductive strips 1 are separated from the gripper 10 according to the determination result. .
즉, 그리퍼(10)를 기 설정된 설정 위치까지 이동시키는 과정에서 그리퍼(10)로부터 전도성 스트립(1)이 이탈되면 해당 전도성 스트립(1)으로는 검지신호가 전송되지 않으므로, 제어부(90)는 전도성 스트립(1) 중 검지신호가 수신된 전도성 스트립(1)에 대해서는 그리퍼(10)에 정상적으로 연결된 것으로 판정하고, 검지신호가 수신되지 않은 전도성 스트립(1)에 대해서는 그리퍼(10)로부터 이탈된 것으로 판정한다.That is, if the conductive strip 1 is separated from the gripper 10 in the process of moving the gripper 10 to a preset setting position, the detection signal is not transmitted to the conductive strip 1, and thus the controller 90 is conductive. It is determined that the conductive strip 1 in which the detection signal is received in the strip 1 is normally connected to the gripper 10, and that the conductive strip 1 in which the detection signal is not received is separated from the gripper 10. do.
이어서, 제어부(90)는 전도성 스트립(1)이 그리퍼(10)로부터 이탈되었는지 여부를 출력부(80)를 통해 출력한다.Subsequently, the controller 90 outputs through the output unit 80 whether the conductive strip 1 is separated from the gripper 10.
더욱이, 그리퍼(10)가 설정 위치까지 이동한 상태에서, 제어부(90)는 커팅 유니트(40)를 제어하여 각각의 전도성 스트립(1)을 커팅한다.Moreover, with the gripper 10 moved to the set position, the controller 90 controls the cutting unit 40 to cut each conductive strip 1.
전도성 스트립(1)을 커팅한 후, 제어부(90)는 검지신호 수신부(50)를 통해 전도성 스트립(1) 각각으로부터 검지신호가 수신되는지 여부를 판단하여 판단 결과에 따라 커팅부(41)의 전도성 스트립 커팅 상태를 판정한다.After cutting the conductive strip 1, the controller 90 determines whether a detection signal is received from each of the conductive strips 1 through the detection signal receiver 50 to determine the conductivity of the cutting part 41 according to the determination result. Determine the strip cutting state.
여기서, 커팅 유니트(40)가 전도성 스트립(1)을 커팅하였음에도 불구하고 검지신호 수신부(50)에 검지신호가 수신되는 경우는, 전도성 스트립(1)이 실제로는 커팅되지 않은 것을 의미한다. 따라서, 제어부(90)는 전도성 스트립(1) 중 검지신호가 수신된 전도성 스트립(1)에 대해서는 커팅 유니트(40)에 의해 비정상적으로 커팅된 것으로 판정하고, 검지신호가 수신되지 않은 전도성 스트립(1)에 대해서는 커팅 유니트(40)에 의해 정상적으로 커팅된 것으로 판정한다.Here, when the detection signal is received by the detection signal receiver 50 even though the cutting unit 40 cuts the conductive strip 1, it means that the conductive strip 1 is not actually cut. Therefore, the controller 90 determines that the conductive strip 1 of the conductive strip 1 has received the detection signal abnormally cut by the cutting unit 40, and the conductive strip 1 has not received the detection signal. ) Is determined to be normally cut by the cutting unit 40.
이어서, 제어부(90)는 커팅 유니트(40)에 의해 전도성 스트립(1) 각각에 대해 비정상적으로 커팅되었는지 여부를 출력한다.Subsequently, the controller 90 outputs whether the cutting unit 40 is abnormally cut for each of the conductive strips 1.
사용자는 커팅 유니트(40)에 의해 전도성 스트립(1)이 비정상적으로 커팅되었는지 여부를 토대로 커팅부(41)의 교체주기 도래 또는 전도성 스트립(1)의 장력 불량 또는 커팅 나이프 불량 등을 추정할 수 있다.The user may estimate the arrival of the replacement cycle of the cutting part 41 or the poor tension of the conductive strip 1 or the poor cutting knife based on whether the conductive strip 1 is abnormally cut by the cutting unit 40. .
도5는 본 발명의 일 실시예에 따른 태양전지 셀의 태빙 장치의 동작 과정을 도시한 순서도이다.5 is a flowchart illustrating an operation process of a tabbing device for a solar cell according to an exemplary embodiment of the present invention.
도5를 참조하면, 태양전지 셀의 태빙 공정에 있어서, 제어부(90)는 그리퍼(10)를 제어하여 그리퍼(10)를 통해 전도성 스트립(1) 각각을 그립한다(단계 S10 참조).Referring to FIG. 5, in the tabbing process of the solar cell, the controller 90 controls the gripper 10 to grip each of the conductive strips 1 through the gripper 10 (see step S10).
그리퍼(10)에 의해 전도성 스트립(1)이 그립되면, 검지신호 전송부(30)는 검지신호를 피딩 클램프(11)를 통해 전도성 스트립(1) 각각으로 전달하고, 검지신호 수신부(50)는 전도성 스트립(1) 각각을 통해 전달된 검지신호를 고정 클램프(42)를 통해 수신한다.When the conductive strip 1 is gripped by the gripper 10, the detection signal transmitter 30 transmits the detection signal to each of the conductive strips 1 through the feeding clamp 11, and the detection signal receiver 50 The detection signal transmitted through each of the conductive strips 1 is received through the fixed clamp 42.
검지신호 수신부(50)에 의해 검지신호가 수신되면, 제어부(90)는 전도성 스트립(1) 각각으로부터 검지신호가 수신되는지 여부를 판단하고(단계 S20 참조), 판단 결과에 따라 제어부(90)는 그리퍼(10)에 전도성 스트립(1) 각각이 정상적으로 그립되었는지 여부를 판정한다(단계 S30 참조).When the detection signal is received by the detection signal receiver 50, the controller 90 determines whether a detection signal is received from each of the conductive strips 1 (see step S20), and according to the determination result, the controller 90 It is determined whether or not each of the conductive strips 1 is normally gripped to the gripper 10 (see step S30).
제어부(90)는 전도성 스트립(1) 중 검지신호가 수신된 전도성 스트립(1)에 대해서는 정상적으로 그립된 것으로 판정하고, 검지신호가 수신되지 않은 전도성 스트립(1)에 대해서는 비정상적으로 그립된 것으로 판정한다. 이어서, 제어부(90)는 전도성 스트립(1)이 정상적으로 그립되었는지 여부를 출력부(80)를 통해 출력한다(단계 S30 참조).The controller 90 determines that the conductive strip 1 has normally been gripped with respect to the conductive strip 1 in which the detection signal has been received, and determines that it has been abnormally gripped with respect to the conductive strip 1 without the detection signal. . Subsequently, the controller 90 outputs through the output unit 80 whether the conductive strip 1 is normally gripped (see step S30).
이어서, 제어부(90)는 그리퍼(10)를 통해 전도성 스트립(1)을 그립한 상태에서 그리퍼 이동부(20)를 제어하여 그리퍼(10)를 기 설정된 설정 위치까지 이동시킨다(단계 S40 참조).Subsequently, the controller 90 controls the gripper moving unit 20 while the conductive strip 1 is gripped through the gripper 10 to move the gripper 10 to a predetermined setting position (see step S40).
이 과정에서 그리퍼(10)는 전도성 스트립(1)을 그립한 상태로 이동하므로, 검지신호 전송부(30)는 검지신호를 피딩 클램프(11)를 통해 전도성 스트립(1)으로 지속적으로 전달하고, 검지신호 수신부(50)는 전도성 스트립(1)으로부터 고정 클램프(42)를 통해 검지신호를 수신한다.In this process, since the gripper 10 moves to the gripped state of the conductive strip 1, the detection signal transmission unit 30 continuously transmits the detection signal to the conductive strip 1 through the feeding clamp 11. The detection signal receiving unit 50 receives the detection signal from the conductive strip 1 through the fixed clamp 42.
그리퍼(10)로 전도성 스트립(1)을 그립한 상태로 그리퍼(10)를 기 설정된 설정 위치까지 이동시키는 과정에서, 제어부(90)는 검지신호 수신부(50)를 통해 전도성 스트립(1) 각각으로부터 검지신호가 수신되는지 여부를 판단한다(단계 S50 참조).In the process of moving the gripper 10 to a predetermined setting position while the conductive strip 1 is gripped by the gripper 10, the controller 90 is configured to detect the conductive strip 1 from each of the conductive strips 1 through the detection signal receiver 50. It is determined whether the detection signal is received (see step S50).
제어부(90)는 단계(S50)에서의 판단 결과에 따라 그리퍼(10)로부터 전도성 스트립(1) 각각의 이탈 여부를 판정하고, 전도성 스트립(1)이 그리퍼(10)로부터 이탈되었는지 여부를 출력부(80)를 통해 출력한다(단계 S60 참조).The controller 90 determines whether each of the conductive strips 1 is separated from the gripper 10 according to the determination result in step S50, and outputs whether or not the conductive strips 1 are separated from the gripper 10. Output through 80 (see step S60).
즉, 그리퍼(10)를 기 설정된 설정 위치까지 이동시키는 과정에서 그리퍼(10)로부터 전도성 스트립(1)이 이탈되면 해당 전도성 스트립(1)으로는 검지신호가 전송되지 않는다. 따라서, 제어부(90)는 전도성 스트립(1) 중 검지신호가 수신된 전도성 스트립(1)에 대해서는 그리퍼(10)에 정상적으로 연결된 것으로 판정하고, 검지신호가 수신되지 않은 전도성 스트립(1)에 대해서는 그리퍼(10)로부터 이탈된 것으로 판정한다.That is, if the conductive strip 1 is separated from the gripper 10 in the process of moving the gripper 10 to a predetermined setting position, a detection signal is not transmitted to the conductive strip 1. Therefore, the control unit 90 determines that the conductive strip 1 of the conductive strip 1 has received the detection signal is normally connected to the gripper 10, and the gripper has no grip on the conductive strip 1 where the detection signal has not been received. Determination is made from (10).
이어서, 그리퍼(10)가 설정 위치까지 이동된 상태에서, 제어부(90)는 커팅 유니트(40)를 제어하여 각각의 전도성 스트립(1)을 커팅한다(단계 S70 참조).Subsequently, with the gripper 10 moved to the set position, the controller 90 controls the cutting unit 40 to cut each conductive strip 1 (see step S70).
제어부(90)는 전도성 스트립(1)을 커팅한 후, 검지신호 수신부(50)를 통해 전도성 스트립(1) 각각으로부터 검지신호가 수신되는지 여부를 판단한다(단계 S80 참조).After cutting the conductive strip 1, the controller 90 determines whether a detection signal is received from each of the conductive strips 1 through the detection signal receiving unit 50 (see step S80).
제어부(90)는 상기한 단계(S80)에서의 판단 결과에 따라 커팅부(41)의 전도성 스트립 커팅 상태를 판정하고, 커팅 유니트(40)에 의해 전도성 스트립(1) 각각에 대해 비정상적으로 커팅되었는지 여부를 출력한다(단계 S90 참조).The controller 90 determines the cutting state of the conductive strip of the cutting unit 41 according to the determination result in step S80, and whether the cutting unit 40 has abnormally cut the conductive strips 1 for each of the conductive strips 1. It is outputted whether or not (see step S90).
즉, 제어부(90)는 검지신호 수신부(50)를 통해 전도성 스트립(1) 각각으로부터 검지신호가 수신되는지 여부를 판단하고, 이때 검지신호가 수신된 전도성 스트립(1)에 대해서는 커팅 유니트(40)에 의해 비정상적으로 커팅된 것으로 판정하고, 검지신호가 수신되지 않은 전도성 스트립(1)에 대해서는 커팅 유니트(40)에 의해 정상적으로 커팅된 것으로 판정한다.That is, the control unit 90 determines whether the detection signal is received from each of the conductive strips 1 through the detection signal receiving unit 50, and at this time, the cutting unit 40 is applied to the conductive strip 1 in which the detection signal is received. It is determined by the cutting unit 40 that it has been abnormally cut by the cutting unit 40, and that the conductive strip 1 on which the detection signal has not been received.
이와 같이 제어부(90)는 태빙 공정에서 각 전도성 스트립(1)별로 검지신호가 수신되는지 여부를 바탕으로 태양전지 셀의 스트링의 제작 과정에서의 결함 여부를 출력함으로써 사용자가 태양전지셀의 제작 과정을 실시간으로 인지할 수 있도록 한다.As such, the controller 90 outputs a defect in the manufacturing process of the string of the solar cell based on whether the detection signal is received for each conductive strip 1 in the tabbing process, thereby allowing the user to manufacture the solar cell. Make it recognizable in real time.
이와 같이 본 실시예에 의하면, 그리퍼(10)로부터 전도성 스트립(1) 각각으로 검지신호가 전달되고, 전도성 스트립(1) 각각을 통해 검지신호가 전달되는지 여부가 판단되며, 판단 결과에 따라 태양전지 셀의 스트링의 제작 과정에서의 결함 여부가 판정된다.As described above, according to the present exemplary embodiment, whether the detection signal is transmitted from the gripper 10 to each of the conductive strips 1 and whether the detection signal is transmitted through each of the conductive strips 1 is determined. It is determined whether there is a defect in the manufacturing process of the string of cells.
또한 본 실시예에 의하면, 태빙 공정에서 전도성 스트립(1)과 태양전지셀의 접합 전에 전도성 스트립(1)의 이탈 여부가 감지되어 제품 완성 전에 제품 불량 여부가 확인될 수 있다. 따라서, 제품 생산시 공정, 시간 및 원가 손실이 최소되고 생산성이 향상된다.In addition, according to the present embodiment, the detachment of the conductive strip 1 is detected before the bonding of the conductive strip 1 and the solar cell in the tabbing process, so that the defective product can be confirmed before the completion of the product. This minimizes process, time and cost losses during product production and improves productivity.
