Description

Technical Field

[0001] The present invention relates to an alignment device and a splicing device including the alignment device, and more particularly to an alignment device capable of adjusting the interval between adjacent solar cell sheets during a splicing process and a splicing device including the alignment device. Background Art

[0002] Typically, solar cells are constructed by placing a diode formed by a pn junction on a substrate. When sunlight strikes a solar cell, excitons, electron-hole pairs, are generated. As the excitons separate, the electrons move to the n-layer and the holes to the p-layer, generating photovoltaic power at the pn junction.

[0003] Typically, a single solar cell can only generate a maximum voltage of about 0.5V, so multiple solar cells are connected in series. This modular product, made by connecting multiple solar cells, is called a solar cell module.

[0004] The tabbing process is a process of forming a solar cell module by electrically connecting the plurality of solar cells by arranging wires on the plurality of solar cells.

[0005] The background art of the present invention is disclosed in Korean Patent Publication No. 10-1058399 (registered on August 16, 2011, invention title: Splicer-tandem device and splice-tandem method). Summary of the Invention

Therefore, it should be understood that the embodiments described in this specification and the structures shown in the drawings are only some of the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, in this application, various equivalents and modifications that can replace them may exist. In addition, when used in this specification, "comprise, include" and / or "comprising, including" specify the existence of the mentioned shapes, numbers, steps, operations, parts, elements and / or combinations thereof, without excluding the existence or addition of one or more other shapes, numbers, steps, operations, parts, elements and / or combinations. In addition, when describing an embodiment of the present invention, "may" or "may be" may include "one or more embodiments of the present invention".

[0060] In addition, in order to help understand the invention, the size of some components may be exaggerated rather than drawn in accordance with the actual scale. In addition, in different embodiments, the same reference numerals may be given to the same components.

[0061] Describing two comparison objects as "the same" means "substantially the same." Therefore, "substantially the same" may include having a deviation that is considered low in the art, for example, within 5%. Furthermore, "uniformity" of any parameter in a predetermined region may mean uniformity over an average angle.

[0062] Although the terms "first," "second," etc. are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from another. Of course, unless otherwise specified, the first component may also be the second component.

[0063] Throughout the specification, unless otherwise specified, each constituent element may be in the singular or the plural.

[0064] Arranging an arbitrary structure "above (or below)" a constituent element or "on (or below)" a constituent element may not only mean arranging the arbitrary structure in contact with the upper surface (or lower surface) of the constituent element, but may also mean that other structures may be interposed between the constituent element and the arbitrary structure arranged above (or below) the constituent element.

[0065] Arranging an arbitrary structure "above (or below)" a constituent element or "on (or below)" a constituent element may not only mean arranging the arbitrary structure in contact with the upper surface (or lower surface) of the constituent element, but may also mean that other structures may be interposed between the constituent element and the arbitrary structure arranged above (or below) the constituent element.

[0066] In addition, when it is described that any component is “connected,” “coupled,” or “connected” to another component, it should be understood that the components may be directly connected or connected to each other, but other components may be “interposed” between the components, or the components may be “connected,” “coupled,” or “connected” through other components.

[0070] In this specification, although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. The terms are used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, boundary layer, or part discussed below may be named the second element, component, region, boundary layer, or part.

[0071] As shown in the accompanying drawings, in order to illustrate the relationship between one element or feature and another element or feature, spatial relative terms such as "beneath", "below", "lower", "above", "upper", etc. may be used in this specification for ease of description.

[0073] Figure 1 is a side view schematically showing the structure of a splicing device according to an embodiment of the present invention, Figure 2 is a cross-sectional view schematically showing the structure of a splicing device according to an embodiment of the present invention.

[0074] Reference Figure 1 and Figure 2The bonding device is a device for connecting solar cells C and wires W to form a solar cell module, and may include a conveying line 10 , a bonding device 20 , a pressing device 30 and an alignment device 40 .

[0075] The conveying line 10 may convey the solar cells C and the wires W. More specifically, the conveying line 10 may function as a structure that continuously conveys the solar cells C and the wires W along a first direction.

[0076] Solar cell C has a semiconductor junction region with a pn junction. When irradiated with energy exceeding a certain level, it generates an electromotive force, converting light energy into electrical energy. The semiconductor material used in solar cell C is not particularly limited, and may include silicon (single crystal, polycrystalline, or amorphous), gallium arsenide, cadmium telluride, cadmium sulfide, indium phosphide, copper indium gallium selenide (CIGS), organic dyes, or mixtures thereof.

[0077] The solar cell C can be arranged in a plurality. The plurality of solar cells C can be arranged along a first direction. The first direction can refer to any direction parallel to the solar cell C. As an example, the first direction can refer to a direction parallel to the solar cell C. Figure 1 The +X axis direction is the reference.

[0078] The solar cell C may include a first surface C1 and a second surface C2 opposite to each other and parallel to the first direction. The first surface C1 and the second surface C2 may function as an anode and a cathode of the solar cell C, respectively. The first surface C1 and the second surface C2 may be spaced apart along the second direction. Here, the second direction is a direction intersecting the first direction, which may mean Figure 1 The +Z axis direction is the reference.

[0079] The wire W may function as a conductor for electrically connecting the plurality of solar cells C. The wire W may electrically connect a pair of solar cells C arranged adjacent to each other in the solar cell module.

[0080] The length of the wire W may extend along a first direction. Both sides of the wire W may be arranged to face a pair of solar cells C adjacent to each other along the first direction. As an example, the wire W may include a first portion W1 facing the first surface C1 of any one of the adjacent pair of solar cells C and a second portion W2 facing the second surface C2 of the remaining one of the adjacent pair of solar cells C.

[0081] The wires W may be provided in plurality and may be arranged between each adjacent solar cell C.

[0082] On one solar cell C, a plurality of wires W may be arranged in parallel along a third direction. Here, the third direction is a direction intersecting the first direction and the second direction, which may refer to a direction intersecting the first direction and the second direction. Figure 1 The +Y axis direction is the reference.

[0083] The wire W may be electrically connected to the solar cell C through a soldering process. In this case, the solar cell C and the wire W may be conveyed in the first direction through the conveyor line 10 with flux applied to their surfaces. Alternatively, the wire W may be electrically connected to the solar cell C through an ECA (Electrically Conductive Adhesive) curing process. In this case, the solar cell C and the wire W may be conveyed in the first direction through the conveyor line 10 with ECA applied to their surfaces.

[0084] The conveying line 10 according to the present embodiment may include a conveying body 110 and a conveying member 120 .

[0085] The transfer body 110 may be disposed to face the second surface C2 of the solar cell C.

[0086] The conveying body 110 according to this embodiment can be configured to move back and forth in a direction parallel to the first direction at a position spaced apart from the second surface C2 of the solar cell C. At the same time, the conveying body 110 can be configured to move back and forth in a direction parallel to the second direction at a position spaced apart from the second surface C2 of the solar cell C. The conveying body 110 can be connected to a power device (not shown) such as a motor or a cylinder, and receive a driving force transmitted from the power device to move in a direction parallel to the first direction and a direction parallel to the second direction.

[0087] The transport body 110 may move cyclically along a set path. As an example, the transport body 110 may move in the second direction, the first direction, the opposite direction of the second direction, and the opposite direction of the first direction in sequence.

[0088] The transfer member 120 may be connected to the transfer body 110 and linked with the movement of the transfer body 110 to move the solar cell sheets C and the wires W in the first direction.

[0089] The transfer member 120 according to this embodiment may extend from the transfer body 110 toward the second surface C2 of the solar cell C. The length direction of the transfer member 120 may extend parallel to the first direction. Therefore, the transfer member 120 may be arranged to simultaneously face the second surfaces C2 of the plurality of solar cell C arranged along the first direction.

[0090] As the conveying body 110 moves in the second direction, the conveying member 120 may come into contact with the second surface C2. Thereafter, as the conveying body 110 moves in the first direction, the conveying member 120 may move the solar cell C and the wire W in the first direction while in contact with the second surface C2 of the solar cell C. Thereafter, as the conveying body 110 moves in a direction opposite to the second direction, the conveying member 120 may be separated from the second surface C2. While the conveying member 120 moves in a direction opposite to the second direction, the solar cell C may be placed on the pressurizing device 30 or a separate support (not shown) to maintain a state of being spaced apart from the conveying member 120. Thereafter, as the conveying body 110 moves in a direction opposite to the first direction, the conveying member 120 may return to its initial position. Therefore, the solar cell C and the wire W may be moved in stages at set time intervals, corresponding to the moving distance of the conveying member 120 in the first direction.

[0091] The bonding device 20 can bond the solar cell C and the wire W conveyed by the conveyor line 10 to each other. As an example, the bonding device 20 may include various types of heating devices for melting the solder layer of the wire W by heating the solar cell C and the wire W conveyed by the conveyor line 10, or for curing the ECA applied to the connection portion of the solar cell C and the wire W.

[0092] The bonding device 20 can operate alternately with the conveyor line 10. As an example, when the conveyor member 120 is separated from the solar cells C and is not conveying the solar cells C and the wires W, the bonding device 20 can heat the solar cells C and the wires W. Furthermore, when the conveyor member 120 is in contact with the solar cells C and is conveying the solar cells C and the wires W, the bonding device 20 can stop heating the solar cells C and the wires W. However, the bonding device 20 is not limited to this operation and can also be configured to operate independently of the conveyor line 10.

[0093] The pressurizing device 30 can function as a structure for fixing the relative position of the wire W with respect to the solar cell C during the bonding process between the solar cell C and the wire W.

[0094] The pressurizing device 30 according to the present embodiment may include a first pressurizing member 310 and a second pressurizing member 320 .

[0095] The first pressing member 310 may be disposed to face the first surface C1 of the solar cell C. The first pressing member 310 may make contact with a first portion W1 of the wire W facing the first surface C1 and pressurize the first portion W1 toward the first surface C1.

[0096] The first pressing member 310 may be provided in plural numbers, and each of the first pressing members 310 may be arranged to face the first surfaces C1 of different solar cell cells C.

[0097] When the solar cell sheets C are moved in the first direction through the transfer line 10 , the first pressing member 310 may be moved together with the solar cell sheets C in the first direction.

[0098] The second pressing member 320 may be disposed to face the second surface C2 of the solar cell C. The second pressing member 320 may make contact with the second portion W2 of the wire W facing the second surface C2 and pressurize the second portion W2 toward the second surface C2.

[0099] The second pressurizing member 320 can selectively pressurize the second portion W2 of the wire W. Specifically, a portion of the second pressurizing member 320 facing the second portion W2 of the wire W can be configured to be capable of contacting or separating from the second portion W2 of the wire W. When the bonding device 20 is in operation, the second pressurizing member 320 can contact the second portion W2 of the wire W, firmly adhering the second portion W2 to the second surface C2. As the solar cell C and the wire W are moved in the first direction via the conveyor line 10, the second pressurizing member 320 can separate from the second portion W2.

[0100] The second pressing member 320 may movably support the second surface C2 of the solar cell C. As an example, the remaining area of ​​the second pressing member 320 excluding the area in contact with the second portion W2 of the wire W may remain in contact with the second surface C2 of the solar cell C. Therefore, when the solar cell C moves in the first direction via the conveyor line 10, the second pressing member 320 may not move along with the solar cell C but may be fixed in position.

[0101] The second pressing member 320 may be provided in plurality. Each second pressing member 320 may be arranged to face the second surface C2 of each different solar cell C. The number of the second pressing members 320 may be less than the number of the first pressing members 310. The number of the second pressing members 320 is not limited to Figure 1 The case shown is the same, and the design can be changed in various amounts according to the moving distance of the conveying member 120 in the first direction, etc.

[0102] The alignment device 40 can adjust the intervals between the plurality of solar cells C conveyed by the conveyor line 10. Therefore, the alignment device 40 can separate the continuous assembly of solar cells C and wires W into solar cell string units consisting of a set number of solar cells C.

[0103] Figure 3is a perspective view schematically showing the structure of an alignment device according to an embodiment of the present invention, Figure 4 FIG. 1 is a side view schematically showing the structure of an alignment device according to an embodiment of the present invention.

[0104] Reference Figures 1 to 4 The alignment device 40 according to this embodiment may include a rail portion 410 , a shuttle 420 , and an adjustment portion 430 .

[0105] The rail portion 410 may function as a structure that guides the movement of the shuttle 420 described later. The rail portion 410 according to the present embodiment may be arranged to face the second surface C2 of the solar cell C at a predetermined interval. The length direction of the rail portion 410 may extend parallel to the first direction. The length of the rail portion 410 may be greater than the sum of the lengths of the plurality of second pressurizing members 320 parallel to the first direction. The rail portion 410 may be fixed to the ground or a separate frame (not shown). The specific shape of the rail portion 410 is not limited to Figure 3 The situation shown in the figure can be changed in design according to various shapes that can guide the movement of the shuttle 420.

[0106] The shuttle 420 may be movably provided on the rail portion 410. The shuttle 420 may be movable along the rail portion 410 in a first direction or in an opposite direction to the first direction.

[0107] A plurality of shuttles 420 may be provided. Each shuttle 420 may movably support a different second pressurizing member 320. The number of shuttles 420 may be formed to correspond to the number of second pressurizing members 320. However, the shuttles 420 are not limited thereto and may directly support the second surface C2 of the solar cell C independently of the conveying member 120 and the second pressurizing member 320.

[0108] The plurality of shuttles 420 according to the present embodiment may include a first shuttle 421 and a second shuttle 422 .

[0109] The first shuttle 421 and the second shuttle 422 may be arranged sequentially along the first direction. That is, the second shuttle 422 may be arranged at a position spaced apart from the first shuttle 421 in the first direction. Therefore, when the first shuttle 421 moves in the first direction, the second shuttle 422 may contact the first shuttle 421 and move together with the first shuttle 421 in the first direction. When the first shuttle 421 moves in a direction opposite to the first direction without an external force acting between the first and second shuttles 421, the first shuttle 421 may separate from the second shuttle 422, and the second shuttle 422 may not move together with the first shuttle 421 in a direction opposite to the first direction.

[0110] The second shuttle 422 may be provided in more than one form. Hereinafter, the second shuttle 422 may be provided in a plurality of forms as an example for explanation, but the second shuttle 422 is not limited thereto and may also be provided in one form.

[0111] The plurality of second shuttles 422 may be arranged along the first direction from the first shuttle 421 .

[0112] When any one of the second shuttles 422 moves in the first direction, a plurality of second shuttles 422 arranged in the first direction from the second shuttle 422 may contact each other and move in the first direction.

[0113] When any one of the second shuttles 422 moves in the second direction without any additional external force acting between adjacent second shuttles 422, the plurality of second shuttles 422 arranged in the first direction from the second shuttle 422 may be separated from the second shuttle 422 and not move in the first direction.

[0114] The first shuttle 421 according to this embodiment may include a first shuttle body 4211 , a main bracket 4212 , and a first connecting bracket 4213 .

[0115] The first shuttle body 4211 may form the general appearance of the first shuttle 421 and integrally support the main bracket 4212 and the first connecting bracket 4213. The specific shape of the first shuttle body 4211 is not limited to Figure 3 and Figure 4 The case shown in the figure can be variously changed in design within the range of the shape of the rail portion 410 that enables it to move back and forth in the first direction or the direction opposite to the first direction.

[0116] The main bracket 4212 and the first connecting bracket 4213 may extend from the first shuttle body 4211. The main bracket 4212 and the first connecting bracket 4213 may function as a structure providing a connection site of the first shuttle 421 to the adjustment portion 430 described later.

[0117] According to the present embodiment, the main bracket 4212 and the first connecting bracket 4213 may extend from the outer surface of the first shuttle body 4211 in a direction parallel to the third direction. The main bracket 4212 and the first connecting bracket 4213 may be arranged in sequence along the first direction. That is, the first connecting bracket 4213 may be arranged at a position spaced apart from the main bracket 4212 by a predetermined distance in the first direction. The main bracket 4212 and the first connecting bracket 4213 may be formed of a ferromagnetic material such as iron. The specific shapes of the main bracket 4212 and the first connecting bracket 4213 are not limited to Figure 3 and Figure 4 The present invention further provides a case shown in FIG. 42 , and various design changes can be made within the range that the first shuttle body 4211 can be arranged to extend from the first shuttle body 4211 and to be spaced apart along the first direction.

[0118] The second shuttle 422 according to this embodiment may include a second shuttle body 4221 , a second connecting bracket 4222 , and a third connecting bracket 4223 .

[0119] The second shuttle body 4221 may form the general appearance of the second shuttle 422 and integrally support the second connecting bracket 4222 and the third connecting bracket 4223. The second shuttle body 4221 may be arranged at a position spaced apart from the first shuttle body 4211 along the first direction. The specific shape of the second shuttle body 4221 is not limited to Figure 3 and Figure 4 The case shown in the figure can be variously changed in design within the range of the shape that enables the rail portion 410 to move back and forth in the first direction or the direction opposite to the first direction.

[0120] The second connecting bracket 4222 and the third connecting bracket 4223 may extend from the second shuttle body 4221. The second connecting bracket 4222 and the third connecting bracket 4223 may function as a structure providing a connection site of the second shuttle 422 to the adjustment part 430 described later.

[0121] According to the present embodiment, the second connecting bracket 4222 and the third connecting bracket 4223 can extend from the outer surface of the second shuttle body 4221 in a direction parallel to the third direction. The second connecting bracket 4222 and the third connecting bracket 4223 can be arranged in sequence along the first direction. That is, the third connecting bracket 4223 can be arranged at a position spaced a predetermined distance from the second connecting bracket 4222 in the first direction. The second connecting bracket 4222 and the third connecting bracket 4223 can be formed of a ferromagnetic material such as iron. The specific shapes of the second connecting bracket 4222 and the third connecting bracket 4223 are not limited to Figure 3 and Figure 4 The present invention further provides a case shown in the figure, and various design changes can be made within the range that it can be arranged to extend from the second shuttle body 4221 and be spaced apart along the first direction.

[0122] The second connection bracket 4222 of the second shuttle 422 arranged adjacent to the first shuttle 421 among the plurality of second shuttles 422 may be arranged to face the first connection bracket 4213 of the first shuttle 421 along the first direction.

[0123] The third connection bracket 4223 formed in any one of a pair of adjacent second shuttles 422 may be arranged to face the second connection bracket 4222 formed in the remaining one of the second shuttles 422 along the first direction.

[0124] The adjustment unit 430 may be connected to the shuttles 420 and adjust the distance between any adjacent pair of shuttles 420. That is, the adjustment unit 430 may function as a structure for increasing or decreasing the interval between any adjacent pair of shuttles 420 by changing the moving directions of the plurality of shuttles 420.

[0125] The regulating portion 430 may include a first regulating member 431 and a second regulating member 432 .

[0126] The first adjusting member 431 may be connected to the first shuttle 421 and move the first shuttle 421 in a first direction or an opposite direction to the first direction.

[0127] Figure 5 FIG. 1 is a perspective view schematically showing the structure of a first adjusting member according to an embodiment of the present invention.

[0128] Reference Figures 1 to 5 , the first regulating member 431 according to the present embodiment may include an actuator 4311 , a conversion member 4312 and a transmission member 4313 .

[0129] The actuator 4311 may generate a driving force for the operation of the first adjustment member 431. The actuator 4311 according to this embodiment may include various types of electric motors that receive externally applied power to generate a rotational force. The actuator 4311 may be coupled to the rail portion 410 or a separate frame to be fixed in position.

[0130] The conversion member 4312 may be connected to the actuator 4311 and convert the driving force of the actuator 4311 into a linear motion parallel to the first direction.

[0131] The conversion member 4312 according to the present embodiment may include a first conversion member 4312 a and a second conversion member 4312 b .

[0132] The first conversion member 4312a can rotate by receiving the driving force transmitted from the actuator 4311. According to this embodiment, the first conversion member 4312a can have a bolt shape with threads formed on the outer peripheral surface. The first conversion member 4312a can be arranged so that the length direction is parallel to the first direction. One end of the first conversion member 4312a can be connected to the output shaft of the actuator 4311. When the actuator 4311 is operated, the first conversion member 4312a can rotate in a clockwise direction or a counterclockwise direction around the central axis.

[0133] The second conversion member 4312b can be connected to the first conversion member 4312a and move in the first direction or the opposite direction of the first direction according to the rotation direction of the first conversion member 4312a. According to this embodiment, the second conversion member 4312b can have a nut shape with threads formed on the inner circumference. The inner circumference of the second conversion member 4312b can be engaged with the outer circumference of the first conversion member 4312a. The second conversion member 4312b can be directly engaged with the first conversion member 4312a, but it can also be indirectly engaged with the threads of the first conversion member 4312a and the second conversion member 4312b via a plurality of cyclically moving balls.

[0134] As the first conversion member 4312 a rotates in a clockwise direction or a counterclockwise direction around the central axis, the second conversion member 4312 b may linearly move in a first direction or a direction opposite to the first direction.

[0135] The transfer member 4313 can be connected to the conversion member 4312 and the first shuttle 421, and can move the first shuttle 421 in conjunction with the linear motion of the conversion member 4312. According to this embodiment, the transfer member 4313 can be arranged between the second conversion member 4312b and the main bracket 4212. One end of the transfer member 4313 can be connected to the second conversion member 4312b. One end of the transfer member 4313 can be integrally fixed to the second conversion member 4312b via welding, bolting, or the like. The other end of the transfer member 4313 can be connected to the main bracket 4212. The other end of the transfer member 4313 can be integrally fixed to the main bracket 4212 via welding, bolting, or the like.

[0136] When the second conversion member 4312 b moves in the first direction, the transfer member 4313 may move in the first direction together with the second conversion member 4312 b and pressurize the main support 4212 in the first direction and move the first shuttle 421 in the first direction.

[0137] When the second conversion member 4312b moves in the opposite direction of the first direction, the transmission member 4313 moves together with the second conversion member 4312b in the opposite direction of the first direction, and pulls the main support 4212 in the opposite direction of the first direction, and moves the first shuttle 421 in the opposite direction of the first direction.

[0138] The second adjustment member 432 may be connected to the second shuttle 422 and selectively allow the second shuttle 422 to move in a direction opposite to the first direction. That is, when the first shuttle 421 moves in a direction opposite to the first direction, the second adjustment member 432 may function as a structure that changes the interval between the first shuttle 421 and the second shuttle 422 or the interval between adjacent second shuttles 422 by allowing or restricting the second shuttle 422 from moving together with the first shuttle 421.

[0139] Figure 6 FIG. 1 is an enlarged view schematically showing the structure of a second regulating member according to an embodiment of the present invention.

[0140] Reference Figure 6 , the second adjusting member 432 according to this embodiment may include a first connecting member 4321 .

[0141] The first connecting member 4321 may be disposed between the first shuttle 421 and the second shuttle 422. The first connecting member 4321 can selectively connect the first shuttle 421 and the second shuttle 422. Specifically, the first connecting member 4321 can function as a structure that connects the first shuttle 421 and the second shuttle 422 to each other or disconnects the first shuttle 421 and the second shuttle 422 using its own driving force. When the first connecting member 4321 connects the first shuttle 421 and the second shuttle 422, the second shuttle 422 can move in a direction opposite to the first direction together with the first shuttle 421. When the first connecting member 4321 disconnects the first shuttle 421 and the second shuttle 422, the second shuttle 422 can be fixed in position without moving in a direction opposite to the first direction together with the first shuttle 421.

[0142] The first connection member 4321 according to the present embodiment may include a first connection body 4321 a and a first electromagnet 4321 b .

[0143] The first connecting body 4321a may be fixed to the second shuttle 422 and arranged to face the first shuttle 421. The first connecting body 4321a according to this embodiment may be arranged between the first connecting bracket 4213 and the second connecting bracket 4222 of the second shuttle 422 arranged adjacent to the first shuttle 421. One end of the first connecting body 4321a may be fixed to the second connecting bracket 4222 of the second shuttle 422 arranged adjacent to the first shuttle 421. The other end of the first connecting body 4321a may extend from the second connecting bracket 4222 of the second shuttle 422 arranged adjacent to the first shuttle 421 in a direction opposite to the first direction.

[0144] As the first shuttle 421 moves in the first direction, the other end of the first connection body 4321a may contact the first connection bracket 4213 of the first shuttle 421. Therefore, when the first shuttle 421 moves in the first direction, the second shuttle 422 may move in the first direction together with the first shuttle 421.

[0145] The first electromagnet 4321b can be disposed on the first connecting body 4321a and receive externally applied power to generate a magnetic force. The first electromagnet 4321b according to this embodiment can be exemplified by various types of electromagnets that can generate or remove a magnetic force depending on whether power is supplied. The first electromagnet 4321b can be disposed inside the first connecting body 4321a. However, the first electromagnet 4321b is not limited thereto and can also be configured to form part or all of the exterior of the first connecting body 4321a.

[0146] The first connecting body 4321a can be fixed to the first shuttle 421 by the magnetic force generated by the first electromagnet 4321b. As an example, as the first electromagnet 4321b generates a magnetic force, an attractive force can be generated between the first connecting bracket 4213 and the second connecting bracket 4222, and the first connecting body 4321a is tightly fixed to the first connecting bracket 4213 by this attractive force.

[0147] When the second shuttle 422 is provided in plurality, the second adjusting member 432 may further include a second connecting member 4322 .

[0148] The second connecting member 4322 may be disposed between an adjacent pair of second shuttles 422. The second connecting member 4322 may selectively connect an adjacent pair of second shuttles 422. In other words, the second connecting member 4322 may function as a structure that connects or disconnects an adjacent pair of second shuttles 422 using its own driving force.

[0149] The second connecting member 4322 may be provided in plurality. Each second connecting member 4322 may be separately arranged between a pair of adjacently arranged second shuttles 422.

[0150] The second connection member 4322 according to the present embodiment may include a second connection body 4322a and a second electromagnet 4322b.

[0151] The second connecting body 4322a can be fixed to any one of the adjacent pair of second shuttles 422. According to this embodiment, the second connecting body 4322a can be arranged between the second connecting bracket 4222 formed in any one of the adjacent pair of second shuttles 422 and the third connecting bracket 4223 formed in the remaining second shuttle 422. One end of the second connecting body 4322a can be fixed to the second connecting bracket 4222 of the second shuttle 422 of the adjacent pair of second shuttles 422 that is positioned relatively far from the first shuttle 421. The other end of the second connecting body 4322a can extend from the second connecting bracket 4222 in a direction opposite to the first direction.

[0152] As the first shuttle 421 moves in the first direction, the other end of the second connection body 4322a may come into contact with the third connection bracket 4223 of the second shuttle 422, one of the adjacent pair of second shuttles 422, which is positioned relatively close to the first shuttle 421. Therefore, when the first shuttle 421 moves in the first direction, the plurality of second shuttles 422 may move in the first direction together with the first shuttle 421.

[0153] The second electromagnet 4322b can be disposed on the second connecting body 4322a and receive power transmitted from the outside to generate a magnetic force. The second electromagnet 4322b according to this embodiment can be exemplified by various types of electromagnets that can generate or release a magnetic force depending on whether power is supplied. The second electromagnet 4322b can be disposed inside the second connecting body 4322a. However, the second electromagnet 4322b is not limited thereto and can also be configured to form part or all of the exterior of the second connecting body 4322a.

[0154] As the magnetic force is generated by the second electromagnet 4322 b , the second connection body 4322 a may be closely fixed to the third connection bracket 4223 of the second shuttle 422 positioned relatively close to the first shuttle 421 in the adjacent pair of second shuttles 422 .

[0155] Hereinafter, the operation of the alignment device 40 according to an embodiment of the present invention will be described.

[0156] Figures 7 to 10 FIG. 1 is a diagram schematically illustrating an operation process of an alignment device according to an embodiment of the present invention.

[0157] Reference Figure 7 When the interval between a pair of solar cells C needs to be adjusted during the conveyance of the solar cells C and the wires W, the actuator 4311 generates a driving force to rotate the first conversion member 4312 a in one direction.

[0158] The second converting member 4312 b moves in the first direction by the rotation of the first converting member 4312 a , and the transmitting member 4313 presses the first shuttle 421 in the first direction.

[0159] The first shuttle 421 moves a set distance in the first direction by the pressing force transmitted from the transmitting member 4313 .

[0160] As the first shuttle 421 moves in the first direction, the first connecting body 4321 a contacts the first connecting bracket 4213 , and the second connecting body 4322 a contacts the third connecting bracket 4223 .

[0161] Therefore, the pressing force transmitted from the transmitting member 4313 is transmitted from the first shuttle 421 to the second shuttle 422 , and the plurality of second shuttles 422 move together with the first shuttle 421 by a set distance in the first direction.

[0162] Reference Figure 8When the interval between the solar cell C located on the first shuttle 421 and the solar cell C located on the second shuttle 422 arranged adjacent to the first shuttle 421 is to be increased, the power supplied to the first electromagnet 4321b is cut off, and the magnetic force generated by the first electromagnet 4321b is released.

[0163] Then, the actuator 4311 generates a driving force to rotate the first conversion member 4312 a in the other direction.

[0164] The second converting member 4312 b moves in the opposite direction to the first direction by the rotation of the first converting member 4312 a , and the first shuttle 421 moves together with the transmitting member 4313 in the opposite direction to the first direction.

[0165] As the magnetic force generated by the first electromagnet 4321 b is no longer generated, the first connection body 4321 a is separated from the first connection bracket 4213 .

[0166] The second shuttle 422 disposed adjacent to the first shuttle 421 does not move in the opposite direction to the first direction, but is fixed at a position moved a set distance in the first direction from an initial position.

[0167] Therefore, the distance between the solar cell C located on the first shuttle 421 and the solar cell C located on the second shuttle 422 disposed adjacent to the first shuttle 421 increases by the set distance.

[0168] Reference Figure 9 , when Figure 7 When the interval between the solar cells C located on any adjacent pair of second shuttles 422 is to be increased in the state, the power supplied to the second electromagnet 4322b located between any adjacent pair of second shuttles 422 is cut off, and the magnetic force generated by the second electromagnet 4322b is released.

[0169] On the other hand, the second electromagnet 4322b and the first electromagnet 4321b arranged in the opposite direction from the first direction receive power supplied from the outside to generate magnetic force.

[0170] Then, the actuator 4311 generates a driving force to rotate the first conversion member 4312 a in the other direction.

[0171] The second converting member 4312 b moves in the opposite direction to the first direction by the rotation of the first converting member 4312 a , and the first shuttle 421 moves together with the transmitting member 4313 in the opposite direction to the first direction.

[0172] The second shuttle 422 positioned relatively close to the first shuttle 421 and the second shuttle 422 arranged in the opposite direction from the second shuttle 422 in any adjacent pair of second shuttles 422 move in the opposite direction of the first direction together with the first shuttle 421 by magnetic force.

[0173] The second shuttle 422 in any adjacent pair of second shuttles 422 positioned relatively far from the first shuttle 421 does not move in the direction opposite to the first direction, but is fixed at a position moved a set distance in the first direction from an initial position.

[0174] Therefore, the interval between the solar cells C located on any adjacent pair of second shuttle members 422 increases by the set distance.

[0175] Reference Figure 10 , as power is all supplied to the first electromagnet 4321b and the plurality of second electromagnets 4322b, the plurality of second shuttles 422 may return to the initial position by the magnetic force generated by the first electromagnet 4321b and the second electromagnet 4322b.

[0176] Hereinafter, a splicing device according to another embodiment of the present invention will be described.

[0177] The splicing device according to this embodiment may be configured to have a different detailed structure from the splicing device and the alignment device 40 according to an embodiment of the present invention.

[0178] Therefore, when describing the joining device according to this embodiment, only the detailed structure of the alignment device 40 that is different from the joining device according to an embodiment of the present invention will be described. For the remaining structure of the joining device according to this embodiment, the description of the joining device according to an embodiment of the present invention can be applied as it is.

[0179] Figure 11 is a perspective view schematically showing the structure of an alignment device according to another embodiment of the present invention, Figure 12 FIG. 1 is a side view schematically showing the structure of a shuttle adjusting member according to another embodiment of the present invention.

[0180] Reference Figure 11 and Figure 12 , the transfer member 4313 according to the present embodiment may be configured not to be directly connected to the main bracket 4212. The other end portion of the transfer member 4313 may be arranged to face the main bracket 4212 at a set distance in a direction parallel to the first direction.

[0181] The adjusting portion 430 according to this embodiment may further include a shuttle adjusting member 433 .

[0182] The shuttle adjusting member 433 may be disposed between the first shuttle 421 and the first adjusting member 431 and selectively allow the first shuttle 421 to move in a direction opposite to the first direction. In other words, the shuttle adjusting member 433 may function as a structure that connects the first shuttle 421 and the transfer member 4313 to each other or disconnects the first shuttle 421 and the transfer member 4313 by its own driving force.

[0183] The shuttle adjusting member 433 according to the present embodiment may include a shuttle connecting body 4331 and a shuttle electromagnet 4332 .

[0184] The shuttle connection body 4331 may be fixed to the first shuttle 421 and arranged to face the first adjustment member 431. The shuttle connection body 4331 according to this embodiment may be arranged between the main bracket 4212 and the transfer member 4313. One end of the shuttle connection body 4331 may be fixed to the main bracket 4212. The other end of the shuttle connection body 4331 may extend from the main bracket 4212 in a direction opposite to the first direction.

[0185] As the transfer member 4313 moves in the first direction, the other end of the shuttle connection body 4331 may contact the transfer member 4313. Therefore, when the transfer member 4313 moves in the first direction, the first shuttle 421 may move in the first direction together with the transfer member 4313.

[0186] The shuttle electromagnet 4332 can be disposed within the shuttle connection body 4331 and generates a magnetic force in response to externally applied power. The shuttle electromagnet 4332 according to this embodiment can be exemplified by various types of electromagnets capable of generating or disabling a magnetic force depending on whether power is supplied. The shuttle electromagnet 4332 can be disposed within the shuttle connection body 4331. However, the shuttle electromagnet 4332 is not limited thereto and can also be configured to form part or all of the exterior of the shuttle connection body 4331.

[0187] The shuttle connection body 4331 may be fixed to the transfer member 4313 by the magnetic force generated by the shuttle electromagnet 4332. As an example, as the shuttle electromagnet 4332 generates the magnetic force, an attractive force may be generated between the main bracket 4212 and the transfer member 4313, and the shuttle connection body 4331 may be tightly fixed to the transfer member 4313 by the attractive force.

[0188] The present invention has been described with reference to the embodiments shown in the accompanying drawings, but this is merely an example, and persons skilled in the art to which this technology pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom.
