Description

Ribbon supply device and its control method{RIBBON SUPPLY APPARATUS AND CONTROL METHOD THEREOF}

The present invention relates to a ribbon supply device and a control method thereof, and more particularly, to a ribbon supply device and a control method for reducing the defect rate when manufacturing a cell as a thin film and improving the production speed of a solar cell. will be.

Currently, human beings are mostly getting energy from oil, coal, nuclear power, and natural gas, and these fossil and nuclear energy sources are predicted to be exhausted in the near future. Therefore, countries around the world are accelerating research and development of new and renewable energy, and among them, photovoltaic power can be obtained anywhere in the sun, and unlike other power generation methods, it is attracting more attention because it has no pollution.

In order to perform photovoltaic power generation, semiconductor devices that convert solar energy into electrical energy are required, which are called solar cells.

In general, only a unit solar cell has a maximum voltage of about 0.5V, so a solar cell must be connected in series. The unit cells are modularized by connecting them to solar cells.

The manufacturing process of the solar cell module can be roughly divided into five processes: a cell test process, a tabbing process, a lay-up process, a lamination process, and a module test.

First, in the cell test process, cells 20 having various electrical properties are classified after testing, and cells having similar electrical properties are classified, and in the second tabbing process, a conductor ribbon is bonded to the solar cell to connect the solar cells in series.

In the third lay-up process, a series of solar cells produced in the tabing process are arranged in the horizontal direction again to form a desired shape, and then low-iron tempered glass, EVA, and back sheet are laminated.

In the fourth lamination process, the laminated solar cell module materials are vacuum-pressed at a high temperature, so that the solar cell module can withstand shock and waterproof.

Finally, the module test process tests whether the completed solar cell module works normally.

On the other hand, the tabing process is the most essential of the above processes. Since the entire solar cell module cannot be used unless the ribbon is cut off or properly bonded, the tabing process determines the quality of the solar cell module.

Looking at the tabbing process schematically, the two strands of ribbon supplied from the ribbon reel are cut, a flux is applied to the solar cell or the ribbon, and the cut ribbon is seated on the solar cell by a gripper, and the sun The cell and ribbon are soldered.

Recently, solar cell cells have become thinner. As the solar cell becomes thinner, the solar cell may be damaged by a pressing force when transferring the solar cell. Further, when the solar cell is soldered, the solar cell may be damaged as the solar cell is bent by heat.

Therefore, there is a need to improve this.

Background of the invention is disclosed in Republic of Korea Patent Publication No. 10-1058399 (2011.08.16 registration, the name of the invention: Taber-stringer and tabbing-stringing method).

The present invention has been devised to improve the above problems, and provides a ribbon supply device and a control method for reducing the defect rate when manufacturing a cell as a thin film and improving the production speed of a solar cell.

The ribbon supply device according to the present invention includes: a first ribbon feeder including a plurality of first ribbon spools on which the ribbon is wound; A second ribbon feeder including a plurality of second ribbon spools on which the ribbon is wound; And it characterized in that it comprises a fixing holder to which the ribbon is released from the first ribbon feeder or the second ribbon feeder is fixed.

A ribbon bonding portion for bonding the ribbon fixed to the fixing holder to the ribbon supplied to the ribbon gripper may be further included.

It may further include a cutting portion for cutting the ribbon fixed to the fixed holder.

The cutting portion may be disposed between the ribbon bonding portion and the fixing holder.

The ribbon bonding portion, a crimping portion that is movably installed on both sides of the ribbon supplied to the ribbon gripper; And it may include a welding portion provided on the crimping portion.

The first ribbon feeder and the second ribbon feeder may be disposed to face each other.

The control method of the ribbon supply device according to the present invention includes: supplying a ribbon of any one of the first ribbon feeder and the second ribbon feeder to the ribbon gripper; Fixing the ribbon of any one of the first ribbon feeder and the second ribbon feeder which does not supply the ribbon to the ribbon gripper to a fixing holder; Determining whether a ribbon is consumed in the first ribbon feeder and the second ribbon feeder; Bonding the ribbon fixed to the fixing holder to the ribbon supplied to the ribbon gripper; And cutting the ribbon fixed to the fixing holder.

The step of bonding the ribbon fixed to the fixed holder to the ribbon supplied to the ribbon gripper may include moving the ribbon bonding portion to close the ribbon fixed to the fixed holder and the ribbon supplied to the ribbon gripper; And bonding the adhered ribbon.

In the step of cutting the end of the ribbon fixed to the fixing holder, the cutting portion may be moved to cut.

According to the present invention, since deformation of the cell is prevented and the cell is pressed as a whole, the defect rate can be reduced when the cell is manufactured as a thin film.

According to the present invention, since the transfer speed of the cell can be increased, there is an effect of improving the production speed of the solar cell.

Hereinafter, embodiments of the tabbing device according to the present invention will be described with reference to the accompanying drawings. In the process of explaining the embodiments of the tabbing device, the thickness of the lines or the size of components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or practice. Therefore, the definition of these terms should be made based on the contents throughout the present specification.

1 is a block diagram showing a tabbing device according to an embodiment of the present invention. 2 is a side view showing a connection form of a cell and a ribbon in a tabbing device according to an embodiment of the present invention.

1 and 2, the tabbing process according to an embodiment of the present invention is a process of connecting the conductor ribbon 40 to the solar cell. The tabbing process includes a cell process, a ribbon process, a flux application process and a soldering process.

In the cell process, one or a plurality of cells 20 are continuously supplied to the cell transfer line in the stacked solar cell (hereinafter referred to as “cell”). In the ribbon process, the ribbon 40 is cut or molded to a certain length. The ribbon 40 is cut or molded to a length that can connect the two cells 20. In the flux application process, the flux may be applied to the cell 20 or the ribbon 40. In the soldering process, the cells 20 and the ribbon 40 are soldered so that a plurality of cells 20 are connected in series. When the flux is applied to the cell 20, a flux application process is disposed between the cell process and the soldering process. In addition, when the flux is applied to the ribbon 40, a flux application process is disposed between the ribbon process and the soldering process. Hereinafter, a case where the flux application process is disposed between the ribbon process and the soldering process to apply the flux to the cell 20 will be described as an example.

The cell supply device 100 is disposed in the cell process, and the ribbon supply device is disposed in the ribbon process. The flux coating device 300 is disposed in the flux coating process, and the soldering device is disposed in the soldering process. The soldering device is a conveyor device 400, a heating device 420 and a transfer device (not shown).

In the soldering process, the ribbon 40 is stacked on the cell 20 after the cell 20 is transferred to the conveyor device 400. At this time, about half of the ribbon 40 is stacked on the cell 20, and the cell 20 is stacked again on the other half of the ribbon 40. As such, as the cell 20 and the ribbon 40 are continuously stacked, the cell 20 is connected in series by the ribbon 40.

Since the cell 20 is made of a metal layer and a resin layer, the cell 20 may be deformed or damaged when heat is applied in the soldering process. Moreover, as the cell 20 is made of a thin film, the cell 20 is more likely to be deformed or damaged by heat.

Below, the apparatus and control method applied to each process will be sequentially described.

3 to 6, the cell supply device 100 includes a magazine unit 110, a magazine transfer unit 120, a lifter unit 130, and a cell transfer device 140.

A plurality of cells 20 are stacked in the magazine unit 110. At this time, the cell 20 stacked on the magazine unit 110 is the cell 20 on which the cell test has been completed. The magazine unit 110 is transferred to the lifter unit 130 by the magazine transfer unit 120. The lifter part 130 raises the magazine part 110 and the cell stacked body. The cell transfer device picks up the cells 20 one by one from the magazine unit 110 and supplies them to the flux coating device 300.

The magazine part 110 includes a magazine base 111, a magazine wall part 113, and an air channel part 115.

The magazine base 111 is moved while seated in the magazine moving part. A plurality of cells 20 are stacked on the magazine base 111. A magazine hole 111a is formed in the magazine base 111 so that the cell lifter 135 of the lifter 130 can pass through when the magazine 110 is transferred to the lifter 130. The magazine hole 111a is formed smaller than the cell 20 to prevent the cells 20 stacked on the magazine base 111 from being discharged to the outside of the magazine unit 110. In addition, an alignment hole portion is formed in the magazine base 111 to communicate with the air channel portion 115. The alignment hole unit aligns the seating position of the magazine unit 110 as it is combined with the alignment nozzle 133 to be described below.

The magazine wall portion 113 is installed in a form erected around the magazine base 111. The magazine wall portion 113 is installed to surround the cell stack. In the center of the magazine wall portion 113, a sensing hole portion 116 is formed along the vertical direction. The sensing hole portions 116 are arranged to face each other on both sides of the magazine wall portion 113. The cell detection unit 117 is disposed in the detection hole unit 116. The cell sensing unit 117 measures the height of the cell stacked body stacked on the magazine unit 110. The cell sensing unit 117 includes a light emitting unit and a light receiving unit disposed to face each other. As the light irradiated from the light emitting unit is received by the light receiving unit, the height of the cell stack can be measured.

The magazine wall portion 113 includes a high wall portion 113a and a low wall portion 113b formed to have a lower height than the high wall portion 113a. A plurality of high wall portions 113a are arranged to face each other in order to prevent separation of the cell stack. The lower wall portion 113b is connected in a bent form to one side of the high wall portion 113a.

The air channel part 115 is formed inside the magazine wall part 113. The air injection hole 115a is formed on the upper side of the magazine wall portion 113. The air injection hole 115a is formed at a height corresponding to the upper side of the cell stacked body when the cell stacked body is stacked on the magazine portion 110. As air is supplied to the air channel unit 115, air is injected through the air injection hole 115a to the upper side of the cell stack. At this time, since the upper cells 20 in the cell stack are floated or separated by the injection pressure of air, the uppermost layer cell 20 can be easily taken out.

The lifter unit 130 includes a magazine lifter 131, an alignment nozzle 133, and a cell lifter 135.

When the magazine unit 110 is transferred to the lifter unit 130 by the magazine transfer unit 120, the magazine base 111 is seated on the upper side of the lifter unit 130. As the magazine lifter 131 moves up and down, the magazine unit 110 moves up and down. As the magazine lifter 131 is raised, the magazine unit 110 is spaced apart from the magazine moving unit. The vertical lift structure of the magazine lifter 131 can be variously changed.

The cell lifter 135 is installed to be movable up and down inside the magazine lifter 131. The cell lifter 135 corresponds to a magazine hole 111a formed in the magazine base 111. As the cell lifter 135 is raised, the height of the cell stack is adjusted as the cell stack stacked on the magazine unit 110 is raised and lowered. As the cell lifter 135 is height-adjusted, the topmost cell 20 in the cell stack may be positioned at the pick-up position. In addition, the cell lifter 135 lifts the cell stacked body so that the upper side of the cell stacked body corresponds to the air injection hole 115a.

A plurality of alignment nozzles 133 are protruded from the magazine lifter 131. When the magazine part 110 reaches the lifter part 130 by the magazine moving part, the alignment nozzle 133 is inserted into the alignment hole (not shown) of the magazine base 111. As the alignment nozzle 133 is inserted into the alignment hole, the magazine part 110 is aligned with the magazine lifter 131. In addition, an air supply unit (not shown) may be installed in the magazine lifter 131 to supply air to the alignment nozzle 133. When air is supplied to the alignment nozzle 133, air is supplied to the air channel portion 115 through the alignment hole. The alignment nozzle 133 serves to supply air to the air channel unit 115 while aligning the seating position of the magazine unit 110.

A cell transfer device is installed on the upper side of the magazine part 110 to adsorb the cell 20 from the magazine part 110 and transfer it to the flux device. Hereinafter, the cell transfer device will be described.

The first embodiment of the cell transfer device in the tabbing device according to an embodiment of the present invention will be described.

7 to 9 are views showing a first embodiment of the cell transfer device in the tabbing device according to an embodiment of the present invention.

Referring to FIGS. 7 to 9, the cell transfer device 140 includes a transfer machine 141, an adsorption head 143, and an adsorption port 145.

The moving machine transfer unit 141 transfers the cells 20 from the cell supply device 100 to the flux coating device 300 one by one or a plurality of cells 20. At this time, in the cell supply device 100, the magazine part 110 is raised to the adsorption position by the lifter part 130. The moving machine moving part 141 can be moved up and down from the upper side of the magazine part 110, and is installed to reciprocate between the cell supply device 100 and the flux coating device 300.

The adsorption head 143 is installed in the transfer device 141. The adsorption head 143 is formed with a concave portion 144 so that the cells 20 stacked on the magazine portion 110 are adsorbed in a bowed shape. The concave surface portion 144 has a shape in which the central portion is formed deeper than both sides so that the central portion of the cell 20 is concave upward. At this time, the concave surface portion 144 has a concave shape in the width direction (Y-axis direction) as shown in FIG. 6, but has a parallel shape in the longitudinal direction (X-axis direction).

The concave surface portion 144 may be formed in a shape that becomes concave toward the center from both sides of the adsorption head 143. For example, a difference in depth between both ends of the concave portion 144 and the center portion may be approximately 0.5-5 mm. The depth of the concave portion 144 may be appropriately changed according to the size of the cell 20 within a range of approximately 0.5-5 mm. For example, if the size of the cell 20 is relatively large, even if the depth of the concave portion 144 is relatively increased, the amount of deformation of the cell 20 is relatively small, so that the concave portion 144 is closer to about 5 mm. It can be formed of. On the other hand, if the size of the cell 20 is relatively small, since the depth of the concave portion 144 must be relatively reduced, the amount of deformation of the cell 20 becomes small, so that the concave portion 144 is formed to a depth close to about 0.5 mm. Can.

Since air is injected from the wall portion of the magazine portion 110 to the upper side of the cell stacked body stacked on the magazine portion 110, the upper cells 20 are slightly injured or separated from the cell stacked body. Since the cell 20 of the uppermost layer is adsorbed to the concave portion 144 of the adsorption head 143 in a floating or spaced state, the cell 20 of the uppermost layer can be easily separated from the cell stacked body while slightly bent by elasticity. have. In addition, it is possible to prevent the two or more cells 20 from being adsorbed and transferred to the adsorption head 143 by vacuum pressure.

In addition, when the cell 20 of the uppermost layer is adsorbed by the adsorption port 145 in a floating or spaced state, the cell 20 is bent round by elastic deformation. At this time, the center of the top layer cell 20 is first separated from the cell 20 below it, and the circumference of the top layer cell 20 is separated slightly later. Therefore, when the uppermost cell 20 is spaced apart from the lower cell 20, it is possible to prevent the uppermost cell 20 from falling instantaneously from the lower cell 20, so that the vacuum pressure between the cells 20 is quickly Can be eliminated or reduced.

In addition, since the top layer cell 20 is bent round by the concave portion 144 of the adsorption head 143, air is rapidly introduced between the top layer cell 20 and the cell 20 below it. Therefore, since the vacuum pressure between the cells 20 is quickly eliminated or reduced, it is possible to suppress the cell 20 from being damaged by the vacuum force and the adsorption force of the suction port 145. In addition, since the uppermost cell 20 is easily separated from the cell 20 directly below, it is possible to improve the adsorption speed and transfer speed of the cell 20. In addition, since the top layer cell 20 is quickly separated, it is possible to suppress damage to the cell 20 due to vacuum pressure between the cells 20 even when the thin film (thin thickness) cell 20 is adsorbed. In addition, since the vacuum pressure of the cell 20 can be quickly released, the adsorption force of the adsorption port 145 can be kept relatively small. Therefore, even if the thin film cell 20 is adsorbed, it can be suppressed that the thin film cell 20 is damaged.

In addition, as the transfer speed of the cell 20 increases, the cell 20 needs to be adsorbed relatively quickly in the cell stacked body. The vacuum pressure of becomes relatively large. However, since the cell 20 of the uppermost layer is adsorbed roundly on the concave portion 144 of the adsorption head 143 in a state in which it is floated by air, the vacuum pressure between the cells 20 can be resolved or reduced more quickly. have. Therefore, since the transfer speed of the cell 20 can be relatively increased, productivity of the solar cell module can be improved. In addition, even when the transfer speed of the cell 20 is increased, it is possible to suppress the cell 20 from being damaged when the cell 20 is separated from the cell stack.

The concave portion 144 may be formed in a curved shape. Since the concave portion 144 is formed in a curved shape, the cell 20 may be bent roundly as the adsorption port 145 adsorbs the top layer cell 20. In addition, since the cell 20 is flexibly elastically deformed in a curved shape, it is possible to prevent stress from being concentrated on a specific portion of the cell 20. Therefore, even if the cell 20 is elastically deformed, it is possible to prevent a specific portion of the cell 20 from being damaged.

The adsorption port 145 is installed on the adsorption head 143 and adsorbs the cell 20 stacked on the magazine portion 110. A vacuum device (not shown) is connected to the adsorption port 145 to suck air from the adsorption port 145 so that a vacuum adsorption force is generated in the adsorption port 145 when the adsorption port 145 contacts the cell 20. do.

The adsorption port 145 may be formed in a bellows or bellows shape such that the top layer cell 20 contracts in the longitudinal direction when adsorbed by vacuum pressure. As the adsorption port 145 is contracted by vacuum pressure, the cell 20 may be more closely adhered to the concave portion 144. Accordingly, it is possible to prevent the cell 20 from being spaced apart from the concave portion 144 when the cell 20 is moved to the adsorption port 145.

The suction port 145 may be disposed at the center of the concave portion 144. Since the adsorption port 145 is disposed at the center of the concave portion 144, the cell 20 may be bent symmetrically to both sides relative to the center as the adsorption port 145 adsorbs the cell 20.

The adsorption port 145 may be formed of a material having wear resistance, corrosion resistance, and elasticity. For example, the adsorption port 145 may be formed of a synthetic resin such as silicone or urethane.

Next, a cell transfer device according to a second embodiment of the present invention will be described. Since the second embodiment is substantially the same as the first embodiment except for the installation form of the adsorption port, in describing the second embodiment, the same reference numerals are given to the same configuration as the first embodiment Will be omitted.

10 is a side view showing a second embodiment of the cell transfer device in the tabbing device according to an embodiment of the present invention.

Referring to FIG. 10, a concave surface portion 144 is formed on a lower surface of the adsorption head 143, and an adsorption port 145 is provided on the concave surface portion 144. The suction port 145 may include a first suction port 145a disposed at the center of the concave portion 144 and a second suction port 145b disposed around the first suction port 145a. Since the first adsorption port 145a and the second adsorption port 145b are disposed around the center and circumference of the concave portion 144, various portions of the cell 20 can be adsorbed. Therefore, since the adsorption force can be distributed to various parts of the cell 20, the cell 20 can be stably adsorbed even if the vacuum pressure of each adsorption port 145 is relatively reduced. In addition, since the adsorption force acts on various parts of the cell 20, the cell 20 can be more quickly separated from the cell stack. In addition, since the cell 20 can be quickly separated from the cell stack, the transfer speed of the cell 20 can be improved. In addition, since the adsorption force acts on various parts of the cell 20, even if the cell 20 of the thin film is adsorbed, it can be suppressed that the cell 20 of the thin film is damaged by the adsorption force.

The length of the first adsorption port 145a may be longer than the length of the second adsorption port 145b. Since the first adsorption port 145a is formed longer than the second adsorption port 145b, when the cell 20 is adsorbed, the first adsorption port 145a and the second adsorption port 145b are substantially simultaneously in the cell 20 It may be in contact with and act as an adsorbent. In addition, since the length of the first adsorption port 145a contracts more when the first adsorption port 145a and the second adsorption port 145b are contracted by vacuum pressure, the cell 20 is concavely bent and separated. Can be.

The number of adsorption ports 145 may be variously changed according to the size of the cell 20. For example, the number of adsorption ports 145 may be increased when the cell 20 is large, and the number of adsorption ports 145 may be decreased when the cell 20 is small.

Next, a cell transfer device according to a third embodiment of the present invention will be described. Since the third embodiment is substantially the same as the first embodiment except for the shape of the adsorption head, the same reference numerals are given to the same configuration as the first embodiment in describing the third embodiment, and the description is given. It will be omitted.

11 is a side view showing a third embodiment of the cell transfer device in the tabbing device according to an embodiment of the present invention.

Referring to FIG. 11, a concave surface portion 144 is formed on the lower surface of the adsorption head 143. The concave surface portion 144 is formed in a stepped shape. The center-side step portion of the concave portion 144 is recessed the most, and the step portion near the circumference of the concave portion 144 may be inclined. Since the concave portion 144 is formed in a stepped shape, a gap between the concave portion 144 and the cell 20 may be relatively large when the adsorption port 145 adsorbs the cell 20. Therefore, when the adsorption head 143 lowers the cell 20 to the moving position, the cell 20 falls more quickly from the concave portion 144, so that the transfer speed of the cell 20 can be relatively improved. .

The number of step portions can be variously changed according to the size of the adsorption head 143. For example, when the adsorption head 143 is large, the number of stepped portions may be increased, and when the adsorption head 143 is small, the number of stepped portions may be decreased.

It will be described with respect to the ribbon supply device in the tabbing device according to an embodiment of the present invention.

12 to 17 are side views showing a ribbon supply device in a tabbing device according to an embodiment of the present invention.

12 to 14, the ribbon supply device includes a first ribbon feeder 210, a second ribbon feeder 220, and a fixing holder 230.

The first ribbon feeder 210 includes a plurality of first ribbon spools 213 wound around the ribbon 40. The number of first ribbon spools 213 is arranged in the first ribbon feeder 210 as many as the number of ribbons 40 simultaneously supplied to each cell 20 (see FIG. 14 ). For example, when three ribbons 40 are supplied to each cell 20 in parallel, three first ribbon spools 213 are disposed on the first ribbon feeder 210. In addition, when five ribbons 40 are supplied to each cell 20 in parallel, five first ribbon spools 213 are disposed on the first ribbon feeder 210.

The second ribbon feeder 220 includes a plurality of second ribbon spools 223 on which the ribbon 40 is wound. In the second ribbon feeder 220, the number of second ribbon spools 223 is arranged by the number of ribbons 40 supplied in parallel to each cell 20. The number of second ribbon spools 223 installed in the second ribbon feeder 220 is installed to be the same as the number of first ribbon spools 213 installed in the first ribbon feeder 210.

One of the first ribbon feeder 210 and the second ribbon feeder 220 supplies the ribbon 40 to a ribbon gripper (not shown: a ribbon griper), and the first ribbon feeder 210 and the second ribbon feeder ( The other one of 220) waits for the ribbon 40 to be supplied. The first ribbon feeder 210 may be disposed to face the second ribbon feeder 220 or not.

A plurality of transfer rollers 231 are installed to guide the ribbons 40 that are released from the first ribbon spool 213 and the second ribbon spool 223, respectively. In addition, the transfer roller 231 may be rotated as the ribbon 40 is transferred.

The ribbon 40 unwound from the first ribbon spool 213 and the second ribbon spool 223 is supplied to the fixing roller 233 after passing through the transfer roller 231. The ribbon 40 past the fixing roller 234 is transferred to the ribbon gripper side.

The ribbon 40 released from the first ribbon feeder 210 or the second ribbon feeder 220 is fixed to the fixing holder 230. The fixed holder 230 is fixed to the first fixed holder 230 to which the ends of the ribbon 40 loosened by the first ribbon feeder 210 and the end of the ribbon 40 loosened from the second ribbon feeder 220 are fixed. It includes a second fixing holder 230. The first fixing holder 230 and the second fixing holder 230 are disposed on both sides of the ribbon 40 being conveyed.

More specifically, when the first ribbon feeder 210 supplies the ribbon 40 to the ribbon gripper, the ribbon 40 released from the second ribbon feeder 220 is fixed to the second fixing holder 230. The second ribbon feeder 220 is ready to supply the ribbon 40. In addition, when the second ribbon feeder 220 supplies the ribbon 40 to the ribbon gripper, the ribbon 40 released from the first ribbon feeder 210 is fixed to the first fixing holder 230, so the first ribbon The feeder 210 is ready to supply the ribbon 40.

When the ribbon 40 is completely consumed in one ribbon feeder, the ribbon 40 of the ribbon spool in the standby state and the ribbon 40 supplied to the ribbon gripper are joined. Then, the ribbon 40 is supplied to the ribbon gripper from the remaining ribbon feeders 210 and 220 in the standby state, and the ribbon spools 213 and 223 of one ribbon feeder 210 and 220 are replaced with new ones while the ribbon 40 is being supplied. can do. Therefore, it is possible to save the time of replacing the new ribbon spools 213 and 223 and the time of releasing the ribbon 40 from the replaced ribbon spools 213 and 223 to the transfer roller 231. Generally, the ribbon spools 213 and 223 are replaced every hour. When the time for replacing the ribbon spools 213 and 223 and the time for releasing the ribbon 40 from the replaced ribbon spools 213 and 223 and walking on the transfer roller 231 are combined It took about 20 minutes. However, according to the present invention, it takes only a time to connect the ribbon 40 supplied to the ribbon gripper and the ribbon 40 of the waiting ribbon spools 213 and 223, so that the replacement time of the ribbon 40 can be significantly shortened.

A ribbon bonding portion 240 for bonding the ribbon 40 fixed to the fixing holder 230 to the ribbon 40 supplied to the ribbon gripper may be further included. For example, when the ribbon 40 is supplied from the first ribbon spool 213 and the ribbon 40 is completely consumed, the ribbon joint 240 is connected to the ribbon 40 and the ribbon gripper of the second ribbon spool 223. Bond the supplied ribbon 40. In addition, while supplying the ribbon 40 from the second ribbon spool 223, when the ribbon 40 is completely consumed, the ribbon joint 240 was supplied to the ribbon 40 and the ribbon gripper of the first ribbon spool 213. The ribbon 40 is joined. Therefore, since the ribbon 40 can be supplied again in a shorter time, the work stoppage time can be shortened and productivity can be improved.

The ribbon bonding portion 240 includes a crimping portion 241 movably installed on both sides of the ribbon 40 supplied to the ribbon gripper, and a welding portion 243 installed on the crimping portion 241. Since the crimping portion 241 is moved from both sides of the ribbon 40 to press the ribbon 40 and then weld, the bonding time of the ribbon 40 can be shortened. In addition, since the welding portion 243 is installed to be moved together with the crimp portion 241, there is no need to install a separate driving device for moving the welding portion 243. In addition, the operator may directly bond the ribbon 40 without installing the welding portion 243 on the ribbon supply device 200.

The cutting unit 250 for cutting the ribbon 40 fixed to the fixed holder 230 may be further included. The cutting unit 250 is installed to be movable up and down. The cutting part 250 automatically cuts the end of the ribbon 40 fixed to the fixed holder 230 after the ribbon 40 fixed to the fixed holder 230 and the ribbon 40 supplied to the ribbon gripper are soldered. do. In addition, the operator may directly cut the end of the ribbon 40 fixed to the fixing holder 230 without installing the cutting unit 250.

It will be described with respect to the operation of the ribbon supply device according to an embodiment of the present invention configured as described above.

15 to 17 are side views showing an operating state of the ribbon supply device in the tabbing device according to an embodiment of the present invention. 18 is a flowchart illustrating a method of controlling a ribbon supply device in a tabbing device according to an embodiment of the present invention.

15 to 18, the first ribbon spool 213 is installed on the first ribbon feeder 210, and the second ribbon spool 223 is installed on the second ribbon feeder 220. The ribbon 40 is supplied to the ribbon gripper from the first ribbon spool 213 of the first ribbon feeder 210 (S11). At this time, the ribbon 40 is released from the first ribbon spool 213 and is transferred along the transfer roller 231 and the fixed roller 233.

After unwinding the ribbon 40 from the second ribbon spool 223 of the second ribbon feeder 220 and winding it on the transfer roller 231, the end of the ribbon 40 is fixed to the fixing holder 230 (S12). At this time, the second ribbon spool 223 of the second ribbon feeder 220 is in a standby state for supplying the ribbon 40.

It is determined whether the ribbon 40 is completely consumed in the first ribbon spool 213 of the first ribbon feeder 210 (S13). While the ribbon 40 is not consumed in the first ribbon spool 213, the ribbon 40 is continuously released from the first ribbon spool 213.

When it is determined that the ribbon 40 is completely consumed in the first ribbon spool 213 of the first ribbon feeder 210, the driving of the first ribbon feeder 210 is stopped. The ribbon bonding portion 240 is moved to bond the ribbon 40 of the second ribbon feeder 220 to the ribbon 40 supplied to the ribbon gripper (S14: see FIG. 15). At this time, the ribbon bonding portion 240 moves to close the ribbon 40 fixed to the fixed holder 230 and the ribbon 40 supplied to the ribbon gripper, and weld the ribbon 40 adhered by the welding portion 243 do. Of course, the operator may directly weld the ribbon 40.

When the ribbon 40 fixed to the fixed holder 230 is joined to the ribbon 40 that was supplied to the ribbon gripper, the cutting part 250 is moved to cut the end of the ribbon 40 fixed to the fixed holder 230. (S15: see FIG. 16). As the end of the ribbon 40 is cut, the ribbon 40 is in a state that can be supplied to the ribbon gripper through the fixing holder 230. Therefore, the ribbon 40 supply can be resumed by welding the ribbon 40 of the second ribbon spool 223, which is in the standby state for supplying the ribbon 40, to the ribbon 40 that has been supplied to the ribbon gripper. Of course, the operator may directly cut the ribbon 40 fixed to the fixing holder 230.

As the second ribbon spool 223 of the second ribbon feeder 220 is driven, supply of the ribbon 40 to the ribbon gripper is resumed (S16). At this time, the ribbon 40 is released from the second ribbon spool 223 and is transported along the transfer roller 231 and the fixed roller 233.

In the state where the second ribbon feeder 220 resumes supplying the ribbon 40, the first ribbon spool 213 is separated from the first ribbon feeder 210. Then, the first ribbon feeder 210 is replaced with a new first ribbon spool 213, the ribbon 40 is unwound from the replaced first ribbon spool 213, hooked to the transfer roller 231, and the ribbon 40 The end of the is fixed to the fixing holder 230 (S17). As such, since the first ribbon spool 213 is replaced while the second ribbon spool 223 supplies the ribbon 40 to the ribbon gripper again, the time required to replace the ribbon spools 213 and 223 can be shortened. Therefore, the productivity of the solar cell module can be improved as the time for which the ribbon spools 213 and 223 are replaced is reduced.

When the ribbon 40 is completely consumed in the second ribbon spool 223 of the second ribbon feeder 220, the first ribbon feeder is joined after bonding the ribbon 40 of the first ribbon feeder 210 in the same manner as above. (210) is driven. In the state where the first ribbon feeder 210 is driven, the second ribbon spool 223 is replaced in the second ribbon feeder 220.

Next, a flux coating device in a tabbing device according to an embodiment of the present invention will be described with reference to the drawings.

19 to 20 is a view showing a flux coating device in a tabbing device according to an embodiment of the present invention.

19 and 20, the cell 20 is supplied from the cell supply device 100 to the flux application device 300. At this time, the cell transfer device 140 (see FIG. 3) adsorbs the cell 20 to the adsorption port 145 and then transfers it to the flux coating device 300.

Flux is a material that improves the adhesion performance when the ribbon 40 is attached to the cell 20. Flux is a mixture of approximately 95% volatiles and 5% solids. When the flux is applied to the cell 20, all of the volatile substances evaporate while the cell 20 is being transported and only solid content is present on the surface of the cell 20.

The flux application device 300 includes a flux stage 340 and a flux application unit 347. The cell receiving unit 310, the vision stage 320 and the alignment stage 330 are disposed on one side of the flux stage 340.

The cell receiving unit 310, the vision stage 320 and the alignment stage 330, and the flux stage 340 are installed with a cell driving device 520. As the cell driving device 520, a belt conveyor, a walking beam transporter, and a transfer transporter may be applied. The belt conveyor transports the cells 20 by one pitch by transporting the belt in a caterpillar. The working beam transporter is moved in the transport direction after the working beam supporting the cell 20 rises to move the cell 20 by one pitch, and the working beam transported by the cell 20 descends and then moves to the original position. The transfer machine adsorbs the cell 20 and places it on the vision stage 320, the alignment stage 330, and the flux stage 340. As for the cell driving device 520, various forms may be applied as long as the cell 20 is transported.

The cell receiving unit 310 is supplied with one cell 20 from the magazine unit 110 by a cell transfer device. The cell 20 of the cell receiving unit 310 is transferred to the vision stage 320. A vision device is installed on the vision stage 320 to read the location of the cell 20. Cell 20 of vision stage 320 is transferred to alignment stage 330. In the alignment stage 330, the cell 20 is aligned to the correct position. The cells 20 aligned in the alignment stage 330 are transferred to the flux stage 340.

The flux injection unit 341 is installed in the flux stage 340. The flux injection unit 341 sprays the flux on one surface of the moved cell 20. Since the flux is sprayed while the cell 20 is being transported, the transport speed of the cell 20 can be improved.

The flux coating unit 347 is disposed on the flux stage 340. The flux coating unit 347 accommodates the flux to apply the flux to the other surface of the cell 20 when the cell 20 is placed on the flux coating unit 347. Since the flux is applied to the surface of the cell 20 while the cell 20 is placed on the flux stage 340, the manufacturing time of the solar cell module can be shortened. Also, when the cell 20 is placed on the flux stage 340, the flux is applied to the cell 20 by contact with the flux coating unit 347, so that the surroundings of the flux stage 340 are compared to the method of spraying the flux. It can prevent contamination by this flux.

A receiving groove portion 343a is formed in the flux stage 340, and a flux coating portion 347 is installed in the receiving groove portion 343a. Since the receiving groove portion 343a shields both sides and the lower side of the flux coating portion 347, the flux coating portion 347 can be at least exposed to the outside. Therefore, it is possible to suppress the flux from polluting the surroundings.

The flux coating unit 347 is disposed in a direction parallel to the direction in which the cells 20 are transferred in the flux coating device 300. Therefore, as the cell 20 is transferred to the flux stage 340, the flux is applied to the cell 20, so that the thin and long flux can be applied to the position where the ribbon 40 is to be installed in the cell 20.

The flux coating unit 347 includes a fixing member 347a disposed in the receiving groove portion 343a, and a sponge member 347b fitted into the fixing member 347a and absorbed by the flux. Since the sponge member 347b is fitted to the fixing member 347a, it is possible to prevent the sponge member 347b from shaking when the cell 20 is moved. In addition, since the fixing member 347a shields both sides of the sponge member 347b, it is possible to suppress the evaporation of the flux from the sponge member 347b.

The fixing member 347a may be detachably installed in the receiving groove 343a. Since the fixing member 347a is detachably installed, the fixing member 347a can be removed and replaced with a new sponge member 347b when the sponge member 347b has reached the end of its life.

The upper end of the sponge member 347b may be disposed slightly higher than the upper surface of the flux stage 340. Therefore, the flux may be applied to the surface of the cell 20 when the cell 20 contacts the upper end of the sponge member 347b.

The flux stage 340 includes a plurality of flux blocks 343 and a flux guide 345.

The flux coating unit 347 is disposed on the plurality of flux blocks 343. At least one flux coating unit 347 is disposed in each flux block 343. The flux guide 345 is coupled to the plurality of flux blocks 343 such that the plurality of movement convexities are moved in a direction perpendicular to the movement direction of the cell 20. The flux guide 345 is fitted to the flux block 343 so that the flux block 343 is slidably moved. Since the flux block 343 is movably installed, the flux coating unit 347 to be replaced after the adjacent flux coating unit 347 is moved to the position of the flux coating unit 347 to be replaced when attempting to replace the sponge member 347b ). Therefore, when the flux coating unit 347 is replaced, since the flux coating process can be continuously performed, the production speed of the solar cell module can be improved.

Of course, the flux stage 340 may be installed so as not to move. At this time, the flux coating unit 347 does not change position.

Next, a first embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention will be described with reference to the drawings.

21 to 24 are views showing a first embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention.

21 to 24, the conveyor device 400 includes a transfer roller portion 440, a tension belt 451, and a transfer belt 453.

The transfer roller parts 440 are disposed on both sides of the base frame 410. The transfer roller part 440 is rotated by a driving device (not shown). A pinion gear portion 442 is formed on an outer circumferential surface of the transfer roller portion 440.

A heating device 420 is installed on the base frame 410 to heat the cell 20 and the ribbon 40. In addition, a vacuum device 430 is installed on the base frame 410 to adsorb the cell 20 and the ribbon 40 by vacuum pressure.

The transfer belt part 450 includes a tension belt 451 and a transfer belt 453.

The tension belt 451 is installed on the transport roller 440 to operate in an endless track. The rack belt part 452 is formed in the tension belt 451 so as to mesh with the gear part of the conveying roller part 440. Since the rack gear portion 452 is formed on the tension belt 451, it is possible to prevent the tension belt 451 from slipping with the transfer roller portion 440.

The transfer belt 453 is connected to the tension belt 451 and transfers the cell 20 and the ribbon 40 by being operated together with the tension belt 451. At this time, in the transfer belt 453, the cells 20 and the ribbon 40 are transferred in a stacked state, and the cells 20 and the ribbon 40 are soldered by heating.

The transfer belt 453 is formed of a porous material to allow air to pass through, and a vacuum device 430 is installed on the base frame 410. When the cell 20 and the ribbon 40 are mounted on the transfer belt 453, the vacuum device 430 sucks air through the transfer belt 453 when it is transferred. At this time, since the cell 20 mounted on the transfer belt 453 is adsorbed to the transfer belt 453 by vacuum pressure, it is possible to suppress the positions of the cell 20 and the ribbon 40 from being changed.

The tension belt 451 is manufactured separately from the transfer belt 453 and then connected to each other. The tension belt 451 is wound around the transfer roller part 440 and installed to handle tension, and the transfer belt 453 is connected to the tension belt 451. Since the tension belt 451 handles most of the tension acting on the conveyor device 400, it is possible to prevent the tension from acting excessively on the transport belt 453. Therefore, it is possible to prevent the transfer belt 453 from being meandered by tension.

The tension belt 451 is formed of a material that is less stretchable than the transfer belt 453 so that it is hardly stretched even when tension is applied. Since the tension belt 451 is formed of a material that is hardly stretched, the tension belt 451 may be installed to be pulled taut on the transport roller 440.

The tension belt 451 is connected to both sides of the transfer belt 453. Since the tension belt 451 is connected to both sides of the transfer belt 453, even if the tension is slightly different in the width direction of the transfer belt 453, the transfer belt 453 can be prevented from being skewed or distorted due to a difference in tension. Accordingly, since the cell 20 and the ribbon 40 placed on the transfer belt 453 can be prevented from being changed, the cell 20 and the ribbon 40 can be accurately positioned at the soldering position.

The tension belt 451 is formed of a metallic material such as stainless steel. Since the tension belt 451 is formed of a metallic material, it is possible to prevent the tension belt 451 from being stretched even if a high tension acts on the tension belt 451.

The transfer belt 453 may be formed of a heat-resistant synthetic resin material such as Teflon. Since the transfer belt 453 is formed of a synthetic resin material, manufacturing and maintenance costs of the conveyor device 400 can be reduced. In addition, since the transfer belt 453 is formed of a synthetic resin material, the selection of the heating device 420 may be more free. That is, since the transfer belt 453 is not a metal material, an induction heating type heating device 420 is applicable. The induction heating type heating device 420 cannot be applied to magnetic materials. In addition, as the induction heating type heating device 420 is applied, a low temperature soldering process is possible. In addition, since a low-temperature soldering process is possible, it is possible to manufacture a thin film cell 20 that is easily damaged by heat. In addition, since the porous transfer belt 453 is formed of a synthetic resin material, the cell 20 may be more closely adhered to the transfer belt 453 when the vacuum device 430 is driven.

A connection member 455 connecting the tension belt 451 and the transfer belt 453 may be further included. Since both sides of the transfer belt 453 are connected to the tension belt 451 so that they do not need to be installed so that the transfer belt 453 is excessively pulled in the transfer direction. Therefore, it is possible to prevent the transfer belt 453 from being distorted or skewed by the tension in the transfer direction.

It will be described with respect to the installation method and operation of the conveyor device 400 according to an embodiment of the present invention configured as described above.

The wound synthetic resin sheet is cut to a constant length to match the length of the transfer belt 453. The transfer belt 453 is manufactured by joining both ends of the synthetic resin sheet. At this time, if both ends of the synthetic resin sheet are not accurately cut in the width direction, or if both ends of the synthetic resin sheet are not precisely joined, a slight difference in length of the transfer belt 453 occurs for each part.

Conventionally, since the conveying belt 453 is wound on the conveying roller part 440 so as to be pulled by the conveying roller part 440, the tension acts largely on the conveying belt 453. Therefore, if the length of the transfer belt 453 is slightly different for each part, the transfer belt 453 is slightly warped or the position in the width direction is variable, so that the transfer belt 453 is operated when the transfer belt 453 is operated in a caterpillar. It can be meandered. When the transfer belt 453 is meandered, the alignment position of the cell 20 is changed, so that the soldering positions of the cell 20 and the ribbon 40 are changed, thereby increasing the defect rate. In addition, meandering control may be difficult due to the elasticity of the transfer belt 453.

However, in the present invention, the tension belt 451 and the transfer belt 453 are separately manufactured and then connected to each other, and the tension belt 451 almost bears the tension required by the conveyor device 400. Further, both sides of the transfer belt 453 are supported by the tension belt 451, and are installed so that the transfer belt 453 is pulled in the width direction. Therefore, it is not necessary to increase the tension so that the transfer belt 453 is excessively pulled in the longitudinal direction in order to prevent the transfer belt 453 from sagging. In addition, since the longitudinal tension of the transfer belt 453 is not excessive, it is possible to prevent the transfer belt 453 from being twisted or skewed even if a slight difference occurs in each part of the length of the transfer belt 453. In addition, even if the transfer belt 453 made of a synthetic resin material is elastic, it is possible to prevent meandering of the belt. In addition, since the transfer belt 453 made of synthetic resin material has excellent soldering quality at the same tact time, it may be advantageous in terms of tact time.

Next, a second embodiment of the conveyor device in the tabbing device according to an embodiment of the present invention will be described in detail with reference to the drawings.

25 to 27 are views showing a second embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention.

25 to 27, the conveyor device 400 includes a base frame 410, a transport roller part 440, a transport belt part 450 and a heating device 420.

The transfer roller part 440 is installed in the base frame 410. The conveying roller part 440 is installed with the conveying belt part 450 wound, and as the conveying roller part 440 is rotated, the conveying belt part 450 is operated in a caterpillar.

The cell 20 and the ribbon 40 are transferred to the transfer belt portion 450 in series. The transfer belt part 450 is formed of a porous material so that air can pass therethrough. The transfer belt part 450 will be described in detail below.

The base frame 410 may further include a vacuum device 430. In the vacuum device 430, a plurality of vacuum tubes are arranged to suck air through the transfer belt unit 450. The vacuum device 430 allows the cell 20 and the ribbon 40 to be vacuum adsorbed on the transfer belt portion 450. Since the cell 20 is transferred in a state of being in close contact with the transfer belt portion 450 by vacuum pressure, it is possible to prevent the cell 20 and the ribbon 40 from being changed during transfer.

The heating device 420 is installed on the base frame 410, and heats the cell 20 and the ribbon 40 conveyed by the transfer belt unit 450. Since the heating device 420 is installed in the base frame 410 located at the lower portion of the transfer belt part 450, the heating device 420 maintains a constant distance from the cell 20 so that soldering performance can be improved. . In addition, since the cell 20 is more closely adhered to the conveying belt part 450 by vacuum pressure, the gap between the cell 20 and the heating device 420 can be maintained uniformly to the thickness of the conveying belt part 450. have.

In addition, since the heating device 420 is disposed under the conveying belt part 450 and a pressing device (not shown) is disposed above the conveying belt part 450, the heating device 420 and the pressing device overlap. It can be prevented from being arranged in the space. Therefore, it is possible to prevent the pressing device from interfering with the heating device 420 when soldering while pressing the cell 20 and the ribbon 40. In addition, since the pressing device that moves up and down need not be designed to avoid the heating device 420, the structure of the pressing device is simplified and the arrangement of the pressing device (not shown) is facilitated. In addition, since the structure of the pressing device is simplified and the installation position is free, the soldering section 414 can be formed in a plurality of sections to enable multi-soldering. Since the soldering section 414 may be formed in a plurality of sections, the soldering time of the cell 20 and the ribbon 40 can be shortened.

In addition, since the pressing device (not shown) is disposed on the upper portion of the transfer belt unit 450, the pressing device does not interfere with the heating device 420. Therefore, since the structure of the pressing device is simplified, it is possible to change the pressing pin 611 to a plate-like structure or a simple structure to minimize damage to the cell 20 when soldering the cell 20 and the ribbon 40. . In addition, since the structure of the pressing pin can be changed to a plate shape, the entire cell can be pressed, so that the ultra-thin cell 20 can be soldered.

The heating device 420 includes an insulating plate 425 installed on the base frame 410 and a heating member 426 installed on the insulating plate 425. The insulating plate 425 electrically separates the heating member 426 from the base frame 410.

An induction heater may be applied to the heating member 426. The induction heater can maintain good soldering performance only by maintaining a constant distance from the object to be soldered. According to the present invention, since the heat generating member 426 is disposed on the base frame 410, the distance between the heat generating member 426 and the cell 20 can be maintained as constant as the thickness of the transfer belt portion 450. Therefore, the soldering performance of the cell 20 and the ribbon 40 can be stably secured. Since an induction heater is installed, a low temperature soldering process is possible. Since the low-temperature soldering process becomes possible, soldering of the ultra-thin cell 20 that is easily damaged at high temperatures is possible.

The heating member 426 is disposed on the upper surface of the insulating plate 425 so as to contact the transfer belt portion 450. At this time, the upper surface of the insulating plate 425 and the upper surface of the heating member 426 form almost the same plane. Therefore, since the distance between the heat generating member 426 and the cell 20 as the object to be soldered can be kept constant as much as the thickness of the transfer belt part 450, soldering performance can be improved.

A plurality of heat generating members 426 may be arranged to be parallel to the transfer direction of the ribbon 40. Since the heating member 426 is arranged parallel to the transfer direction of the ribbon 40, the heating member 426 can heat only the portion where the ribbon 40 is located. Therefore, since the portion heated in the cell 20 can be reduced, it is possible to suppress deformation and damage as the cell 20 is heated.

The base frame 410 includes a preheating section 412, a soldering section 414, and a post-heating section 416. The heating device 420 is disposed in the soldering section 414. After the object to be soldered (the cell 20 and the ribbon 40) is preheated in the preheating section 412, it flows into the soldering section 414, and is slowly cooled in the postheating section 416 after being soldered. Therefore, since the object to be soldered can be prevented from being rapidly heated or cooled, it is possible to suppress the object to be soldered from being damaged by heat.

22 to 24 are views showing a first embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention.

22 to 24, the transfer belt unit 450 includes a tension belt 451 and a transfer belt 453.

The tension belt 451 is installed on the transport roller 440 to operate in an endless track. The rack belt part 452 is formed in the tension belt 451 so as to mesh with the gear part of the conveying roller part 440. Since the rack gear portion 452 is formed on the tension belt 451, it is possible to prevent the tension belt 451 from slipping with the transfer roller portion 440.

The transfer belt 453 is connected to the tension belt 451 and transfers the cell 20 and the ribbon 40 by being operated together with the tension belt 451. At this time, in the transfer belt 453, the cells 20 and the ribbon 40 are transferred in a stacked state, and the cells 20 and the ribbon 40 are soldered by heating.

The transfer belt 453 is formed of a porous material to allow air to pass through, and a vacuum device 430 is installed on the base frame 410. When the cell 20 and the ribbon 40 are mounted on the transfer belt 453, the vacuum device 430 sucks air through the transfer belt 453 when it is transferred. At this time, since the cell 20 mounted on the transfer belt 453 is adsorbed to the transfer belt 453 by vacuum pressure, it is possible to suppress the positions of the cell 20 and the ribbon 40 from being changed.

The tension belt 451 is manufactured separately from the transfer belt 453 and then connected to each other. The tension belt 451 is wound around the transfer roller part 440 and installed to handle tension, and the transfer belt 453 is connected to the tension belt 451. Since the tension belt 451 handles most of the tension acting on the conveyor device 400, it is possible to prevent the tension from acting excessively on the transport belt 453. Therefore, it is possible to prevent the transfer belt 453 from being meandered by tension.

The tension belt 451 is formed of a material that is less stretchable than the transfer belt 453 so that it is hardly stretched even when tension is applied. Since the tension belt 451 is formed of a material that is hardly stretched, the tension belt 451 may be installed to be pulled taut on the transport roller 440.

The tension belt 451 is connected to both sides of the transfer belt 453. Since the tension belt 451 is connected to both sides of the transfer belt 453, even if the tension is slightly different in the width direction of the transfer belt 453, the transfer belt 453 can be prevented from being skewed or distorted due to a difference in tension. Accordingly, since the cell 20 and the ribbon 40 placed on the transfer belt 453 can be prevented from being changed, the cell 20 and the ribbon 40 can be accurately positioned at the soldering position.

The tension belt 451 is formed of a metallic material such as stainless steel. Since the tension belt 451 is formed of a metallic material, it is possible to prevent the tension belt 451 from being stretched even if a high tension acts on the tension belt 451.

The transfer belt 453 may be formed of a heat-resistant synthetic resin material such as Teflon. Since the transfer belt 453 is formed of a synthetic resin material, manufacturing and maintenance costs of the conveyor device 400 can be reduced. In addition, since the transfer belt 453 is formed of a synthetic resin material, the selection of the heating device 420 may be more free. That is, since the transfer belt 453 is not a metal material, an induction heating type heating device 420 is applicable. The induction heating type heating device 420 cannot be applied to magnetic materials. In addition, as the induction heating type heating device 420 is applied, a low temperature soldering process is possible. In addition, since a low-temperature soldering process is possible, it is possible to manufacture a thin film cell 20 that is easily damaged by heat. In addition, since the porous transfer belt 453 is formed of a synthetic resin material, the cell 20 may be more closely adhered to the transfer belt 453 when the vacuum device 430 is driven.

A connection member 455 connecting the tension belt 451 and the transfer belt 453 may be further included. Since both sides of the transfer belt 453 are connected to the tension belt 451 so that they do not need to be installed so that the transfer belt 453 is excessively pulled in the transfer direction. Therefore, it is possible to prevent the transfer belt 453 from being distorted or skewed by the tension in the transfer direction.

It will be described with respect to the installation method and operation of the conveyor device according to an embodiment of the present invention configured as described above.

The wound synthetic resin sheet is cut to a constant length to match the length of the transfer belt 453. The transfer belt 453 is manufactured by joining both ends of the synthetic resin sheet. At this time, if both ends of the synthetic resin sheet are not accurately cut in the width direction, or if both ends of the synthetic resin sheet are not precisely joined, a slight difference in length of the transfer belt 453 occurs for each part.

Conventionally, since the conveying belt is wound on the conveying roller so as to be pulled by the conveying roller, tension is greatly exerted on the conveying belt. Therefore, if the length of the conveying belt is slightly different for each part, the conveying belt may be slightly warped or the position in the width direction may be changed, so that the conveying belt may be meandered when the conveying belt is operated in a caterpillar. When the transfer belt is meandered, the alignment position of the cell 20 is changed, so that the soldering positions of the cell 20 and the ribbon 40 are changed, thereby increasing the defect rate. In addition, meandering control may be difficult due to the elasticity of the transfer belt.

However, in the present invention, the tension belt 451 and the transfer belt 453 are separately manufactured and then connected to each other, and the tension belt 451 almost bears the tension required by the conveyor device 400. Further, both sides of the transfer belt 453 are supported by the tension belt 451, and are installed so that the transfer belt 453 is pulled in the width direction. Therefore, it is not necessary to increase the tension so that the transfer belt 453 is excessively pulled in the longitudinal direction in order to prevent the transfer belt 453 from sagging. In addition, since the longitudinal tension of the transfer belt 453 is not excessive, it is possible to prevent the transfer belt 453 from being twisted or skewed even if a slight difference occurs in each part of the length of the transfer belt 453. In addition, even if the transfer belt 453 made of a synthetic resin material is elastic, it is possible to prevent meandering of the belt. In addition, since the transfer belt 453 made of synthetic resin material has excellent soldering quality at the same tact time, it may be advantageous in terms of tact time.

Next, a third embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention will be described with reference to the drawings. Since the third embodiment is substantially the same as the second embodiment except for the shape of the soldering section, in describing the second embodiment, the same configuration as the first embodiment is given the same reference numerals and the description thereof is omitted. Shall be

28 is a view showing a third embodiment of the conveyor device in the tabbing device according to an embodiment of the present invention. 29 is a view showing a fourth embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention.

28 and 29, the base plate includes a preheating section 412, a plurality of soldering sections 414, and a post heating section 416. The preheating section 412, the plurality of soldering sections 414, and the post-heating section 416 are sequentially arranged along the transport direction of the cell 20. The heating device 420 is disposed in the soldering section 414.

The cell 20 and the ribbon 40 must be soldered for about 3 seconds to be sufficiently joined. Since the cell 20 and the ribbon 40 take about 3 seconds for soldering, if there is one soldering section 414, the cell 20 is transferred 1 pitch every 3 seconds.

Since a plurality of soldering sections 414 are continuously formed, soldering time in the soldering sections 414 can be shortened. For example, if two soldering sections 414 are installed, the first soldering section 414 is soldered for 1.5 seconds, and the second soldering section 414 is soldered for 1.5 seconds, so the cell in the conveyor device 400 (20) can be transferred by one pitch every 1.5 seconds. Therefore, when the two soldering sections 414 are formed, the transfer speed of the cell 20 can be doubled, so that the productivity of the solar cell module can be increased by about twice. In addition, when three soldering sections 414 are installed, the soldering can be performed for one second in each soldering section 414, so that the cell 20 can be transferred by one pitch every second in the conveyor device 400. have. Therefore, when the three soldering sections 414 are formed, since the transfer speed of the cell 20 is about three times faster, the productivity of the solar cell module can be increased by about three times.

The soldering section 414 may be disposed between the preheating section 412 and the post-heating section 416. Therefore, since the cell 20 can be prevented from being heated or cooled abruptly, the cell 20 can be prevented from being damaged.

In the heating device 420, the heating member 426 may be arranged in parallel with the transfer direction of the cell 20 (see FIG. 28). Since the heat generating member 426 is disposed parallel to the transfer direction of the cell 20, the portion corresponding to the ribbon 40 can be intensively heated.

In addition, in the heating device 420, the heating member 426 may be disposed perpendicular to the transfer direction of the cell 20 (see FIG. 29). The installation form of the heating member 426 can be variously changed.

Next, a first embodiment of a soldering device in a tabbing device according to an embodiment of the present invention will be described in detail with reference to the drawings.

22 to 24 are views showing a first embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention.

22 to 24, the soldering device includes a conveyor device 400, a vacuum device 430, a compression belt 510, a traveling device 520 and a heating device 420.

The conveyor device 400 includes a base frame 410, a heating device 420, a transfer roller portion 440, and a transfer belt portion 450.

The transfer roller part 440 is installed in the base frame 410. The conveying roller part 440 is installed with the conveying belt part 450 wound, and as the conveying roller part 440 is rotated, the conveying belt part 450 is operated in a caterpillar.

The cell 20 and the ribbon 40 are transferred to the transfer belt portion 450 in series. The transfer belt part 450 will be described in detail below.

The heating device 420 is installed on the base frame 410, and heats the cell 20 and the ribbon 40 conveyed by the transfer belt unit 450. The heating device 420 is disposed along the longitudinal direction of the base frame 410. Since the heating device 420 is installed in the base frame 410 located at the lower portion of the transport belt part 450, the heating device 420 maintains a constant gap to the thickness of the cell 20 and the transport belt part 450. It can be maintained to improve the soldering performance.

The vacuum device 430 is installed on the conveyor device 400. At this time, the vacuum device 430 is disposed under the transfer belt portion 450 to form a vacuum pressure in the transfer belt portion 450. The vacuum device 430 includes a plurality of vacuum tubes (not shown) to suck air.

The transfer belt part 450 includes a tension belt 451 and a transfer belt 453.

The tension belt 451 is installed on the transport roller 440 to operate in an endless track. The rack belt part 452 is formed in the tension belt 451 so as to mesh with the gear part of the conveying roller part 440. Since the rack gear portion 452 is formed on the tension belt 451, it is possible to prevent the tension belt 451 from slipping with the transfer roller portion 440.

The transfer belt 453 is connected to the tension belt 451 and transfers the cell 20 and the ribbon 40 by being operated together with the tension belt 451. At this time, in the transfer belt 453, the cells 20 and the ribbon 40 are transferred in a stacked state, and the cells 20 and the ribbon 40 are soldered by heating.

The transfer belt 453 is formed of a porous material to allow air to pass through, and a vacuum device 430 is installed on the base frame 410. When the cell 20 and the ribbon 40 are mounted on the transfer belt 453, the vacuum device 430 sucks air through the transfer belt 453 when it is transferred. At this time, since the cell 20 mounted on the transfer belt 453 is adsorbed to the transfer belt 453 by vacuum pressure, it is possible to suppress the positions of the cell 20 and the ribbon 40 from being changed.

The tension belt 451 is manufactured separately from the transfer belt 453 and then connected to each other. The tension belt 451 is wound around the transfer roller part 440 and installed to handle tension, and the transfer belt 453 is connected to the tension belt 451. Since the tension belt 451 handles most of the tension acting on the conveyor device 400, it is possible to prevent the tension from acting excessively on the transport belt 453. Therefore, it is possible to prevent the transfer belt 453 from being meandered by tension.

The tension belt 451 is formed of a material that is less stretchable than the transfer belt 453 so that it is hardly stretched even when tension is applied. Since the tension belt 451 is formed of a material that is hardly stretched, the tension belt 451 may be installed to be pulled taut on the transport roller 440.

The tension belt 451 is connected to both sides of the transfer belt 453. Since the tension belt 451 is connected to both sides of the transfer belt 453, even if the tension is slightly different in the width direction of the transfer belt 453, the transfer belt 453 can be prevented from being skewed or distorted due to a difference in tension. Accordingly, since the cell 20 and the ribbon 40 placed on the transfer belt 453 can be prevented from being changed, the cell 20 and the ribbon 40 can be accurately positioned at the soldering position.

The tension belt 451 is formed of a metallic material such as stainless steel. Since the tension belt 451 is formed of a metallic material, it is possible to prevent the tension belt 451 from being stretched even if a high tension acts on the tension belt 451.

The transfer belt 453 may be formed of a heat-resistant synthetic resin material such as Teflon. Since the transfer belt 453 is formed of a synthetic resin material, manufacturing and maintenance costs of the conveyor device 400 can be reduced. In addition, since the transfer belt 453 is formed of a synthetic resin material, the selection of the heating device 420 may be more free. That is, since the transfer belt 453 is not a metal material, an induction heating type heating device 420 is applicable. The induction heating type heating device 420 cannot be applied to magnetic materials. In addition, as the induction heating type heating device 420 is applied, a low temperature soldering process is possible. In addition, since a low-temperature soldering process is possible, it is possible to manufacture a thin film cell 20 that is easily damaged by heat. In addition, since the porous transfer belt 453 is formed of a synthetic resin material, the cell 20 may be more closely adhered to the transfer belt 453 when the vacuum device 430 is driven.

A connection member 455 connecting the tension belt 451 and the transfer belt 453 may be further included. Since both sides of the transfer belt 453 are connected to the tension belt 451 so that they do not need to be installed so that the transfer belt 453 is excessively pulled in the transfer direction. Therefore, it is possible to prevent the transfer belt 453 from being distorted or skewed by the tension in the transfer direction.

30 and 31 are views showing a first embodiment of a soldering device in a tabbing device according to an embodiment of the present invention.

30 and 31, the crimping belt 510 is disposed above the conveyor device 400. The crimping belt 510 is installed in a stretched state to contact the conveyor device 400. Since the crimping belt 510 is installed in a stretched state, as the vacuum device 430 forms a vacuum pressure in the conveying belt part 450, the crimping belt 510 is attached to the conveying belt part 450 of the conveyor device 400. Is squeezed. The pressing force of the transfer belt portion 450 and the pressing belt 510 may be adjusted by the vacuum device 430.

Since the crimping belt 510 is compressed to the conveying belt portion 450 by vacuum pressure, the cell 20 and the ribbon 40 are positioned between the conveying belt portion 450 and the crimping belt 510. Accordingly, it is possible to prevent the soldering positions of the cell 20 and the ribbon 40 from being changed when the cell 20 and the ribbon 40 are transferred by the transfer belt unit 450. In addition, since the crimping belt 510 presses the cell 20 and the ribbon 40 while making a surface contact with the cell 20 and the ribbon 40 as a whole, the cell 20 is heated by the heat when the cell 20 is soldered. It can prevent bending. In addition, it is possible to manufacture an ultra-thin cell 20 that is easily bent by heat. In addition, since the cell 20 can be prevented from being locally compressed by a structure such as a pressing pin, the cell 20 can be prevented from being damaged by local pressure. In addition, since the cell 20 can be prevented from being deformed by heat, the ultra-thin cell 20 can be soldered. In addition, since the cell 20 and the ribbon 40 are transferred while the crimping belt 510 and the transfer belt 453 are compressed under vacuum pressure, the cell 20 can be soldered while being transferred. Since the cell 20 is soldered while being transferred, the soldering time can be shortened. In addition, since the cell 20 is transported in a fully pressurized state by the crimping belt 510 and the conveying belt 453, even if the movement precision of the crimping belt 510 and the conveying belt 453 is relatively low, the belt skew or Slip can be prevented.

In addition, since the cell 20 and the ribbon 40 are compressed to the transfer belt portion 450, the distance between the heating device 420 and the cell 20 is relatively close, so the cell 20 and the ribbon 40 are As it heats faster, soldering performance can be improved.

The crimping belt 510 is installed to operate in a caterpillar. Since the crimping belt 510 is operated in a caterpillar, the cell 20 and the ribbon 40 may be compressed while being transported together with the transfer belt 453.

The crimping belt 510 is conveyed at the same speed as the conveying belt 453 of the conveyor device 400. Since the crimping belt 510 and the transfer belt 453 can be prevented from slipping when being transferred, the cell 20 and the ribbon 40 can be disposed at the correct soldering position.

The driving device 520 transports the compression belt 510. Since the traveling device 520 transports the crimping belt 510, the crimping belt 510 can be transported at the same speed as the transport belt 453.

The traveling device 520 supports both sides of the compression belt 510 such that the lower side of the compression belt 510 is stretched and the upper side of the compression belt 510 is pulled. Since the driving device 520 is installed to pull the upper side of the crimping belt 510, the crimping belt 510 can be adjusted to be the same as the conveying speed of the conveying belt 453. Various types of driving devices 520 may be applied as long as the lower side of the compression belt 510 is stretched and the upper side of the compression belt 510 is pulled. An example of such a driving device 520 will be described.

The traveling device 520 includes a plurality of traveling rollers 521 and tension removing rollers 525.

The plurality of running rollers 521 are installed to support the crimping belt 510. Some driving rollers 521 are disposed on one side of the crimping belt 510, and some driving rollers 521 are disposed on the other side of the crimping belt 510. In addition, some of the driving rollers 521 may be disposed in the middle portion of the crimping belt 510. The position of the transfer belt 453 may be appropriately changed in consideration of the length, deflection, and tension of the crimping belt 510.

The tension removing roller 525 is installed to correspond to the running roller 521. The tension removing roller 525 supports the crimping belt 510 together with the running roller 521 so that the crimping belt 510 is stretched. Although the tension removing roller 525 is shown to be installed only on both sides of the crimping roller, the tension removing roller 525 can be installed at various positions as long as the tension on the lower side of the crimping belt 510 is removed.

In addition, the tension removing roller 525 is installed to squeeze both sides of the crimping belt 510 together with the running roller 521. Therefore, it can be installed to be pulled by the running roller 521 and the tension removing roller 525 on the upper side of the tension removing roller 525. Since the upper section of the crimping belt 510 is installed to have a constant tension, by controlling the speed at which the upper section of the crimping belt 510 is conveyed, the transport speed of the crimping belt 510 and the transport belt 453 is maintained to be the same. Can.

The heating device 420 may be disposed inside or above the conveyor device 400. Since the crimping belt 510 and the transfer belt 453 transfer the cells 20 and the ribbon 40 by compressing them by vacuum pressure, the installation position of the heating device 420 can be freely changed. In addition, since the crimping belt 510 and the transfer belt 453 are soldered in a state in which the cell 20 and the ribbon 40 are compressed, a structure for pressing the cell 20 on the upper side of the conveyor device 400 is installed. You do not have to do.

Further, the heating device 420 may be disposed both inside and above the conveyor device 400. That is, the heating device 420 includes a first heating device 421 installed on the conveyor device 400 and a second heating device 422 installed on the upper side of the conveyor device 400. Since the first heating device 421 and the second heating device 422 heat the cell 20 and the ribbon 40 on both sides, the soldering performance of the cell 20 and the ribbon 40 can be improved.

The first heating device 421 may include an induction heater. The induction heater can maintain good soldering performance only by maintaining a constant distance from the object to be soldered. According to the present invention, since the first heating device 421 is disposed on the base frame 410, the distance between the first heating device 421 and the cell 20 will be maintained constant as the thickness of the transport belt portion 450. Can. Therefore, the soldering performance of the cell 20 and the ribbon 40 can be stably secured. Since an induction heater is installed, a low temperature soldering process is possible. In addition, since the low-temperature soldering process becomes possible, soldering of the ultra-thin cell 20 that is easily damaged at high temperatures becomes possible.

The first heating device 421 is disposed on the upper surface of the insulating plate 425 so as to contact the transfer belt portion 450. At this time, the upper surface of the insulating plate 425 and the upper surface of the first heating device 421 form the same plane. Therefore, since the distance between the heat generating member 426 and the cell 20 as the object to be soldered can be kept constant as much as the thickness of the transfer belt part 450, soldering performance can be improved.

The second heating device 422 may be a non-contact heating device 420 that heats the cell 20 and the ribbon 40 in a non-contact manner. Since the crimping belt 510 and the conveying belt portion 450 transfer the cells 20 and the ribbons 40 in a compressed state by vacuum pressure, the non-contact heating device 420 includes the cells 20 and the ribbons 40 ) To heat the cells 20 and the ribbon 40 to be soldered. As the non-contact heating device 420, an induction heater, an electric resistance heater, or the like may be applied.

The soldering device may further include a cleaning device 530 installed to clean the crimping belt 510. Since the cleaning device 530 removes foreign substances attached to the crimping belt 510, as the crimping belt 510 contacts the cell 20 and the ribbon 40, the cell 20 and the ribbon 40 are contaminated. Can be suppressed. Various types of cleaning devices 530 may be applied as long as the surface of the compression belt 510 can be cleaned.

The base plate is formed with a preheating section 412, a soldering section 414, and a post heating section 416. The preheating section 412, the soldering section 414, and the post-heating section 416 are sequentially arranged along the transport direction of the cell 20. The heating device 420 is disposed in the soldering section 414.

The cell 20 and the ribbon 40 must be soldered for about 3 seconds to be sufficiently joined. Since the cell 20 and the ribbon 40 take about 3 seconds for soldering, if there is one soldering section 414, the cell 20 is transferred 1 pitch every 3 seconds.

A plurality of soldering sections 414 may be continuously formed. Since the plurality of soldering sections 414 are continuously formed, the soldering time of the cell 20 and the ribbon 40 can be shortened. For example, when two soldering sections 414 are installed, the first soldering section 414 is soldered for 1.5 seconds, and the second soldering section 414 is soldered for 1.5 seconds, so the conveyor device 400 The cell 20 can be transferred by one pitch every 1.5 seconds. Accordingly, when the two soldering sections 414 are formed, the productivity of the solar cell module may be increased by about two times as the transfer speed of the cell 20 is doubled. In addition, when three soldering sections 414 are installed, the soldering can be performed for one second in each soldering section 414, so that the cell 20 can be transferred by one pitch every second in the conveyor device 400. have. Therefore, when the three soldering sections 414 are formed, since the transfer speed of the cell 20 is about three times faster, the productivity of the solar cell module can be increased by about three times.

The soldering section 414 may be disposed between the preheating section 412 and the post-heating section 416. Therefore, since the cell 20 can be prevented from being heated or cooled abruptly, the cell 20 can be prevented from being damaged.

The operation of the soldering apparatus according to the embodiment of the present invention configured as described above will be described.

The cell 20 and the ribbon 40 are arranged in series in the transfer belt part 450. As the transfer belt part 450 is transferred, the cell 20 and the ribbon 40 are transferred. At this time, the transfer belt unit 450 may be transferred by one pitch.

As the vacuum device 430 is driven, air is sucked through the transport belt unit 450. At this time, since the lower side of the crimping belt 510 is stretched to contact the conveying belt portion 450, the crimping belt 510 is compressed to the conveying belt portion 450 by the vacuum pressure of the vacuum device 430. At this time, the cell 20 and the ribbon 40 are uniformly pressed by the pressing belt 510 as a whole.

The cell 20 and the ribbon 40 are transferred to the soldering section 414 through the preheating section 412. At this time, the cell 20 and the ribbon 40 conveyed in the soldering section 414 correspond to the heating device 420 in a state pressed by the crimping belt 510 and the conveying belt part 450. When heat energy is applied to the cell 20 and the ribbon 40 in the heating device 420, the cell 20 and the ribbon 40 are soldered. At this time, since the cell 20 and the ribbon 40 are pressed by the crimping belt 510 and the transfer belt, the cell 20 and the ribbon 40 can be stably soldered.

The cell 20 and the ribbon 40 soldered by the heating device 420 are transferred to the post-heating section 416. The soldered cell 20 and the ribbon 40 are cooled to a constant temperature and then discharged to the conveyor device 400.

Next, a first embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention will be described in detail with reference to the drawings.

21 to 24 are views showing a first embodiment of a conveyor device in a tabbing device according to an embodiment of the present invention. 32 and 33 are views showing a first embodiment of a pressing device in a soldering device of a tabbing device according to an embodiment of the present invention.

22 to 24, the soldering device includes a conveyor device 400, a first pressing device (610: see Fig. 32), and a second pressing device (620: see 32).

The conveyor device 400 includes a base frame 410, a heating device 420, a vacuum device 430, a transfer roller portion 440 and a transfer belt portion 450. The transfer belt part 450 includes a tension belt 451 and a transfer belt 453.

The tension belt 451 is installed on the transport roller 440 to operate in an endless track. The rack belt part 452 is formed in the tension belt 451 so as to mesh with the gear part of the conveying roller part 440. Since the rack gear portion 452 is formed on the tension belt 451, it is possible to prevent the tension belt 451 from slipping with the transfer roller portion 440.

The transfer belt 453 is formed of a porous material to allow air to pass through, and a vacuum device 430 is installed on the base frame 410. When the cell 20 and the ribbon 40 are mounted on the transfer belt 453, the vacuum device 430 sucks air through the transfer belt 453 when it is transferred.

The tension belt 451 is manufactured separately from the transfer belt 453 and then connected to each other. The tension belt 451 is wound around the transfer roller part 440 and installed to handle tension, and the transfer belt 453 is connected to the tension belt 451. Since the tension belt 451 handles most of the tension acting on the conveyor device 400, it is possible to prevent the tension from acting excessively on the transport belt 453.

The tension belt 451 is formed of a material that is less stretchable than the transfer belt 453 so that it is hardly stretched even when tension is applied. Since the tension belt 451 is formed of a material that is hardly stretched, the tension belt 451 may be installed to be pulled taut on the transport roller 440.

The tension belt 451 is connected to both sides of the transfer belt 453. Since the tension belt 451 is connected to both sides of the transfer belt 453, even if the tension is slightly different in the width direction of the transfer belt 453, the transfer belt 453 can be prevented from being skewed or distorted due to a difference in tension. Accordingly, since the cell 20 and the ribbon 40 placed on the transfer belt 453 can be prevented from being changed, the cell 20 and the ribbon 40 can be accurately positioned at the soldering position.

The tension belt 451 is formed of a metallic material such as stainless steel. Since the tension belt 451 is formed of a metallic material, it is possible to prevent the tension belt 451 from being stretched even if a high tension acts on the tension belt 451.

The transfer belt 453 may be formed of a heat-resistant synthetic resin material such as Teflon. Since the transfer belt 453 is formed of a synthetic resin material, manufacturing and maintenance costs of the conveyor device 400 can be reduced. In addition, since the transfer belt 453 is formed of a synthetic resin material, an induction heating type heating device 420 is applicable. In addition, as the induction heating type heating device 420 is applied, a low temperature soldering process is possible.

A connection member 455 connecting the tension belt 451 and the transfer belt 453 may be further included. Since both sides of the transfer belt 453 are connected to the tension belt 451 so that they do not need to be installed so that the transfer belt 453 is excessively pulled in the transfer direction.

32 and 33 are views showing a first embodiment of a pressing device in a soldering device of a tabbing device according to an embodiment of the present invention.

Referring to FIGS. 32 and 33, the first pressing device 610 is transferred in a state in which the soldering object is pressed, and then releases the pressing of the soldering object and then returns to the home position HP. The second pressurizing device 620 is transferred to the pressurized object alternately with the first pressurizing device 610, and then releases pressurization of the soldering object and then returns to the home position HP.

The first pressing device 610 includes a first driving unit 615, a second driving unit 616, and a third driving unit 617, which is transported in the three directions to the first pressing device 610. The first drive unit 615 moves the first pressing device 610 along the transfer direction of the transfer belt unit 450. The second driving unit 616 moves the first pressing device 610 along the vertical direction (height direction) of the transfer belt unit 450. The third driving unit 617 moves the first pressing device 610 along the width direction of the transfer belt unit 450.

The second pressing device 620 includes a first driving unit 625, a second driving unit 626, and a third driving unit 627 that is transported in the three directions to the second pressing device 620. The first drive unit 625 moves the second pressing device 620 along the transfer direction of the transfer belt unit 450. The second driving unit 626 moves the second pressing device 620 along the vertical direction (height direction) of the transfer belt unit 450. The third driving unit 627 moves the second pressing device 620 along the width direction of the transfer belt unit 450.

Since the first pressing device 610 and the second pressing device 620 alternately transfer the soldering object in a pressurized state, the soldering object is continuously pressed while being transferred, and the heating device 420 while the soldering object is being moved It can be soldered by. Therefore, the time during which the object to be soldered is soldered can be shortened.

The first pressing device 610 is transported 1 pitch in a state in which the soldering object is pressed and then released to the home position HP after releasing the pressing, and the second pressing device 620 is provided with the first pressing device 610. Alternately, the object to be soldered is conveyed 1 pitch in a pressurized state, and then returned to the home position (HP). Since the first pressurization device 610 and the second pressurization device 620 alternately solder the object to be soldered by one pitch, the soldering object can be transferred according to the speed at which the soldering object is supplied to the conveyor device 400 one by one. have. Therefore, it is possible to reduce the time to stop the soldering object during the time during which the soldering object is soldered in the conveyor device 400. For example, the soldering object may be supplied to the conveyor device 400 at intervals of 1 second, and it may take a time of about 3 seconds for the soldering object to be sufficiently soldered. In this case, since the first pressing device 610 and the second pressing device 620 alternately transfer the soldering object by 1 pitch in units of 1 second, soldering may be completed while the soldering object is moved 3 pitches. Therefore, since the object to be soldered is soldered while being moved 3 pitches for 3 seconds, it is possible to make the soldering speed about three times faster than in the prior art. The soldering speed may be appropriately changed depending on the speed at which the soldering object is supplied to the conveyor device 400 one by one and the soldering time of the soldering object.

When the first pressing device 610 presses the soldering object in the home position (HP) and transfers it by one pitch, the second pressing device 620 moves to one side of the conveyor device 400 and then returns to the home position (HP). Will return. At this time, since the second pressing device 620 is located away from the conveyor device 400 so as not to interfere with the first pressing device 610, the movement path of the first pressing device 610 and the second pressing device 620 It is possible to prevent the return path of is arranged at a position that interferes with each other.

In addition, when the second pressing device 620 presses the object to be soldered at the home position (HP) and conveys it by one pitch, the first pressing device 610 is moved to one side of the conveyor device 400, and then the home position (HP ). At this time, since the first pressing device 610 is located away from the conveyor device 400 so as not to interfere with the second pressing device 620, the movement path of the second pressing device 620 and the first pressing device 610 It is possible to prevent the return path of is arranged at a position that interferes with each other.

The first pressing device 610 and the second pressing device 620 may be disposed to be movable on one side in the width direction of the conveyor device 400. Therefore, since the first pressing device 610 and the second pressing device 620 are moved only on one side in the width direction of the conveyor device 400, the operator is located on the other side in the width direction of the conveyor device 400, and the conveyor device 400 The transfer belt 453 can be replaced. In addition, the conveyor device 400 can be repaired without dismantling the first pressing device 610 or the second pressing device 620.

Any one of the first pressing device 610 and the second pressing device 620 may be returned to the home position HP while the object to be soldered is moved one pitch. Therefore, since the first pressing device 610 and the second pressing device 620 are simultaneously moved in the opposite direction by one pitch, it is possible to shorten the soldering time of the object to be soldered. That is, since the other pressing device is returned in the opposite direction while one pressing device is being transported, it is possible to prevent the time at which the pressing device is returned from affecting the soldering time.

A plurality of pressing pins 611 may be formed on the first pressing device 610 to press the soldering object. In addition, a plurality of pressing pins 611 may be formed in the second pressing device 620 to press the soldering object. A pressure pin 611 of the second pressure device 620 may be disposed between the pressure pins 611 of the first pressure device 610. Therefore, when one pressing device presses the object to be soldered and the rest of the pressing devices release pressure from the object to be soldered, it is possible to prevent interference with each other. In addition, since the pressing pins 611 of the first pressing device 610 and the second pressing device 620 are disposed to be offset from each other, the first pressing device 610 and the second pressing device 620 are moved to the overlapped space. It can be installed as possible. Therefore, the installation space can be reduced.

A plurality of soldering sections 414 may be continuously formed in the conveyor device 400. Since the plurality of soldering sections 414 are continuously formed, soldering may be completed while one soldering object is transferred multiple times by one pitch. For example, when the soldering time is 3 seconds and three soldering sections 414 are formed, soldering objects may be soldered while being transferred to adjacent soldering sections 414 by 1 pitch every 1 second. At this time, when looking at one object to be soldered, it takes 3 seconds of soldering time, but on the whole, the object to be soldered is soldered at the three soldering sections 414 at the same time. have.

The soldering method of the soldering apparatus according to the embodiment of the present invention configured as described above will be described. In this embodiment, it will be described based on the case where three soldering sections are formed on the conveyor device.

33 and 34 are views illustrating a control method according to the first embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention.

33 and 34, the object to be soldered is supplied to the conveyor device 400 every predetermined time. The soldering object is connected in series to the transfer belt 453. The conveying belt 453 of the conveyor device 400 is conveyed by one pitch. The object to be soldered is preheated in the preheating section 412 while being transported along the transfer belt 453.

The first pressing device 610 is moved in the width direction of the conveyor device 400 and is moved to the conveyor device 400 (S31). The heating device 420 heats the soldering ball in the conveyor device 400 to a temperature suitable for soldering.

The first pressing device 610 contacts the upper surface of the soldering object to press the soldering object, and the second pressing device 620 is moved to one side in the width direction of the conveyor device 400 (S32). At this time, the object to be soldered is pressed by the pressing pin 611 of the first pressing device 610 to be in close contact with the transfer belt 453 of the conveyor device 400. In addition, the second pressing device 620 is moved to one side of the conveyor device 400 and does not interfere with the second pressing device 620 when the first pressing device 610 is transferred. Therefore, the first pressing device 610 and the second pressing device 620 are in a state in which they can be moved to opposite sides.

The first pressing device 610 transfers the object to be soldered one pitch to move to the first soldering section 414, and the second pressing device 620 returns to the home position HP (S33). At this time, the conveying belt 453 of the conveyor device 400 is moved one pitch with the first pressing device 610. Since the first pressing device 610 is transported one pitch in a state in which the object to be soldered is pressed, the soldering time may be shortened as the object to be soldered is moved along with the first pressing device 610 to be soldered. In addition, since the second pressing device 620 may return to the home position HP together with the first pressing device 610, the time during which the second pressing device 620 is moved to the home position HP is soldering time. It will not affect.

The first pressing device 610 is stopped for a predetermined time in a state in which the object to be soldered is pressed (S34). For example, when three soldering sections 414 are formed in the conveyor device 400 and the soldering time of the soldering object is 3 seconds, the soldering object is stopped for 1 second in the first soldering section 414. The object to be soldered is soldered for 1 second in the first soldering section 414.

The second pressing device 620 contacts the upper surface of the soldering object to press the soldering object, and the first pressing device 610 is moved to one side in the width direction of the conveyor device 400 to release the pressing of the soldering object (S35) ). At this time, the object to be soldered is pressed by the pressing pin 611 of the second pressing device 620 to be in close contact with the transfer belt 453 of the conveyor device 400. In addition, the second pressing device 620 is moved to one side of the conveyor device 400, so that the second pressing device 620 does not interfere when the second pressing device 620 is transferred. Therefore, the second pressing device 620 and the second pressing device 620 are in a state in which they can be moved to opposite sides.

The second pressing device 620 transfers the object to be soldered by one pitch to move to the second soldering section 414, and the first pressing device 610 returns to the home position HP (S36). At this time, the conveying belt 453 of the conveyor device 400 is moved one pitch with the second pressing device 620. Since the second pressing device 620 is transported one pitch in a state in which the soldering object is pressed, the soldering time may be shortened as the soldering object is soldered while being moved together with the second pressing device 620. In addition, since the first pressing device 610 may be returned to the home position HP together with the second pressing device 620, the time for the first pressing device 610 to move to the home position HP is soldering time. It will not affect.

In addition, since the transfer belt 453 of the conveyor device 400 moves one pitch with the second pressing device 620, a new soldering object is positioned in the first soldering section 414.

The second pressing device 620 is stopped for a predetermined time in a state in which the object to be soldered is pressed (S37). For example, when three soldering sections 414 are formed on the conveyor device 400, and the soldering time of the soldering object is 3 seconds, the soldering object is in the first soldering section 414 and the second soldering section 414. It is stopped for 1 second. The object to be soldered is soldered for 1 second in the first soldering section 414 and the second soldering section 414.

The first pressing device 610 is moved to press the soldering object, and the second pressing device 620 is moved to one side in the width direction of the conveyor device 400. At this time, the first pressing device 610 transfers the object to be soldered by one pitch to move to the first soldering section 414, the second soldering section 414, and the third soldering section 414, and the second pressing device 620 Returns to the home position (HP). The first pressing device 610 is stopped for a predetermined time in a state in which the object to be soldered is pressed (S34). For example, if three soldering sections 414 are formed on the conveyor device 400, and the soldering time of the soldering object is 3 seconds, the soldering object is the first soldering section 414, the second soldering section 414, In the third soldering section 414, it is stopped for 1 second. In the third soldering section 414, the soldering object is finished with soldering.

The object to be soldered in the third soldering section 414 is moved to the post-heating section 416 when the transfer belt 453 is conveyed 1 pitch. The soldering object cooled in the post-heating section 416 is transferred along the transfer belt 453 and then transferred to a later process by a transfer device or the like.

As described above, since the first pressing device 610 and the second pressing device 620 alternately transfer the soldering object by one pitch, soldering may be performed while the soldering object is being transferred. Therefore, since the soldering time can be shortened, the production speed of the solar cell module can be increased.

In addition, since a plurality of soldering sections 414 are formed in the conveyor device 400, soldering is completed when the object to be soldered passes all of the plurality of soldering sections 414. Therefore, since the object to be soldered is soldered little by little while sequentially passing through the plurality of soldering sections 414, the transfer speed of the soldering object can be increased by a multiple of the soldering section 414. For example, when there are three soldering sections 414, the transfer speed of the soldering object can be increased by about three times as compared with the case of one soldering section 414.

35 and 36, the soldering device includes a conveyor device 400, a first pressing device 610, and a second pressing device 620.

The conveyor device 400 transports the object to be soldered. The conveyor device 400 may have the same form as the conveyor device according to the first embodiment of the present invention. The same reference numerals are given to the same configuration as in the first embodiment, and description thereof will be omitted.

When the first pressing device 610 presses the object to be soldered at the home position (HP) by one pitch, the second pressing device 620 moves to the upper side of the conveyor device 400 and then moves to the home position (HP). Will return. At this time, since the second pressing device 620 is located above the conveyor device 400 so as not to interfere with the first pressing device 610, the movement path of the first pressing device 610 and the second pressing device 620 ) Can be prevented from being disposed at positions where the return paths interfere with each other.

The first pressurizing device 610 includes a first driving part 615 and a second driving part 616 that is transported in two directions. The first drive unit 615 moves the first pressing device 610 along the transfer direction of the transfer belt unit 450. The second driving unit 616 moves the first pressing device 610 along the vertical direction of the transfer belt unit 450.

In addition, when the second pressing device 620 presses the object to be soldered at the home position (HP) by one pitch, the first pressing device 610 is moved to the upper side of the conveyor device 400 and then moves to the home position (HP ). At this time, since the first pressing device 610 is located above the conveyor device 400 so as not to interfere with the second pressing device 620, the movement path of the second pressing device 620 and the first pressing device 610 ) Can be prevented from being disposed at positions where the return paths interfere with each other.

The second pressing device 620 includes a first driving unit 625 and a second driving unit 626 to which the second pressing device 620 is transferred in two directions. The first drive unit 625 moves the second pressing device 620 along the transfer direction of the transfer belt unit 450. The second driving unit 626 moves the second pressing device 620 along the vertical direction of the transfer belt unit 450.

The first pressing device 610 is moved up and down on one side in the width direction of the conveyor device 400 and is disposed to be movable along the transport direction of the conveyor device 400. In addition, the second pressing device 620 is moved up and down on the other side in the width direction of the conveyor device 400 and is disposed to be movable along the transport direction of the conveyor device 400. Since the first pressurizing device 610 and the second pressurizing device 620 are vertically arranged on both sides of the conveyor, the installation space in the width direction of the conveyor device 400 can be reduced.

Any one of the first pressing device 610 and the second pressing device 620 may be returned to the home position HP while the object to be soldered is moved one pitch. Therefore, since the first pressing device 610 and the second pressing device 620 are simultaneously moved in the opposite direction by one pitch, it is possible to shorten the soldering time of the object to be soldered. That is, since the other pressing device is returned in the opposite direction while one pressing device is being transported, it is possible to prevent the time at which the pressing device is returned from affecting the soldering time.

A plurality of pressing pins 611 may be formed on the first pressing device 610 to press the soldering object. In addition, a plurality of pressing pins 611 may be formed in the second pressing device 620 to press the soldering object. A pressure pin 611 of the second pressure device 620 may be disposed between the pressure pins 611 of the first pressure device 610. Therefore, when one pressing device presses the object to be soldered and the rest of the pressing devices release pressure from the object to be soldered, it is possible to prevent interference with each other. In addition, since the pressing pins 611 of the first pressing device 610 and the second pressing device 620 are disposed to be offset from each other, the first pressing device 610 and the second pressing device 620 are moved to the overlapped space. It can be installed as possible. Therefore, the installation space can be reduced.

A plurality of soldering sections 414 may be continuously formed in the conveyor device 400. Since the plurality of soldering sections 414 are continuously formed, soldering may be completed while one soldering object is transferred multiple times by one pitch. For example, when the soldering time is 3 seconds and three soldering sections 414 are formed, soldering objects may be soldered while being transferred to adjacent soldering sections 414 by 1 pitch every 1 second. At this time, when looking at one soldering object, the soldering time of 3 seconds is required, but when viewed as a whole, the soldering object is simultaneously soldered in three soldering sections 414, and as the soldering speed is increased by a multiple of the soldering section 414, the solar cell The manufacturing work of the module can be accelerated.

The control method of the second embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention configured as described above will be described. In this embodiment, it will be described based on the case where three soldering sections are formed on the conveyor device.

36 and 37 are views illustrating a control method of the second embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention.

36 and 37, the object to be soldered is supplied to the conveyor device 400 every predetermined time. The soldering object is connected in series to the transfer belt 453. The conveying belt 453 of the conveyor device 400 is conveyed by one pitch. The object to be soldered is preheated in the preheating section 412 while being transported along the transfer belt 453.

The first pressing device 610 is lowered from the upper side of the conveyor device 400 and is located in the conveyor device 400 (S41). The heating device 420 heats the soldering section in the conveyor device 400 to a temperature suitable for soldering.

The first pressing device 610 contacts the upper surface of the soldering object to press the soldering object, and the second pressing device 620 is moved to the upper side of the conveyor device 400 (S42). At this time, the object to be soldered is pressed by the pressing pin 611 of the first pressing device 610 to be in close contact with the transfer belt 453 of the conveyor device 400. In addition, the second pressing device 620 is raised to the upper side of the conveyor device 400 and does not interfere with the first pressing device 610 when the first pressing device 610 is transported along the conveyor device 400. Therefore, the first pressing device 610 and the second pressing device 620 are in a state in which they can be moved to opposite sides.

The first pressing device 610 transfers the object to be soldered by one pitch to move to the first soldering section 414, and the second pressing device 620 returns to the home position HP in an elevated state from the conveyor device 400 It becomes (S43). At this time, the conveying belt 453 of the conveyor device 400 is moved one pitch with the first pressing device 610. Since the first pressing device 610 is transported one pitch in a state in which the object to be soldered is pressed, the soldering time may be shortened as the object to be soldered is moved along with the first pressing device 610 to be soldered. In addition, since the second pressing device 620 may be returned to the home position HP together with the first pressing device 610 in a raised state, the second pressing device 620 is moved to the home position HP Time will not affect soldering time.

The first pressing device 610 is stopped for a predetermined time in a state in which the object to be soldered is pressed (S34). For example, when three soldering sections 414 are formed in the conveyor device 400 and the soldering time of the soldering object is 3 seconds, the soldering object is stopped for 1 second in the first soldering section 414. The object to be soldered is soldered for 1 second in the first soldering section 414.

The second pressing device 620 descends to press the soldering object, and the first pressing device 610 is lifted from the conveyor device 400 to release the pressing of the soldering object (S45). At this time, the object to be soldered is pressed by the pressing pin 611 of the second pressing device 620 to be in close contact with the transfer belt 453 of the conveyor device 400. In addition, the first pressing device 610 is moved to the upper side of the conveyor device 400 to be in a state that does not interfere with the second pressing device 620 when the second pressing device 620 is transferred. Therefore, the second pressing device 620 and the second pressing device 620 are in a state in which they can be moved to opposite sides.

The second pressing device 620 transfers the object to be soldered by one pitch to move to the second soldering section 414, and the first pressing device 610 returns to the home position HP (S36). At this time, the conveying belt 453 of the conveyor device 400 is moved one pitch with the second pressing device 620. Since the second pressing device 620 is transported one pitch in a state in which the soldering object is pressed, the soldering time may be shortened as the soldering object is soldered while being moved together with the second pressing device 620. In addition, since the first pressing device 610 may be returned to the home position HP together with the second pressing device 620, the time for the first pressing device 610 to move to the home position HP is soldering time. It will not affect.

In addition, since the transfer belt 453 of the conveyor device 400 moves one pitch with the second pressing device 620, a new soldering object is positioned in the first soldering section 414.

The second pressing device 620 is stopped for a predetermined time in a state in which the object to be soldered is pressed (S37). For example, when three soldering sections 414 are formed on the conveyor device 400, and the soldering time of the soldering object is 3 seconds, the soldering object is in the first soldering section 414 and the second soldering section 414. It is stopped for 1 second. The object to be soldered is soldered for 1 second in the first soldering section 414 and the second soldering section 414.

The first pressing device 610 is moved to press the soldering object, and the second pressing device 620 is moved to the upper side of the conveyor device 400. At this time, the first pressing device 610 transfers the object to be soldered by one pitch to move to the first soldering section 414, the second soldering section 414 and the third soldering section 414, and the second pressing device 620 Is returned to the home position (HP) in a raised state from the conveyor device (400). The first pressing device 610 is stopped for a predetermined time in a state in which the object to be soldered is pressed (S34). For example, if three soldering sections 414 are formed on the conveyor device 400, and the soldering time of the soldering object is 3 seconds, the soldering object is the first soldering section 414, the second soldering section 414, In the third soldering section 414, it is stopped for 1 second. In the third soldering section 414, the soldering object is finished with soldering.

The object to be soldered in the third soldering section 414 is moved to the post-heating section 416 when the transfer belt 453 is conveyed 1 pitch. The soldering object cooled in the post-heating section 416 is transferred along the transfer belt 453 and then transferred to a later process by a transfer device or the like.

As described above, since the first pressing device 610 and the second pressing device 620 alternately transfer the soldering object by one pitch, soldering may be performed while the soldering object is being transferred. Therefore, since the soldering time can be shortened, the production speed of the solar cell module can be increased.

In addition, since a plurality of soldering sections 414 are formed in the conveyor device 400, soldering is completed when the object to be soldered passes all of the plurality of soldering sections 414. Therefore, since the object to be soldered is soldered little by little while sequentially passing through the plurality of soldering sections 414, the transfer speed of the soldering object can be increased by a multiple of the soldering section 414. For example, when there are three soldering sections 414, the transfer speed of the soldering object can be increased by about three times as compared with the case of one soldering section 414.

Next, a tabbing device according to another embodiment of the present invention will be described in detail with reference to the drawings.

38 and 39 are views showing a tabbing device according to another embodiment of the present invention.

38 and 39, the tabbing device includes a cell transfer unit 710, a first ribbon transfer unit 720, an alignment unit 730, a cell ribbon transfer unit 740, and a second ribbon transfer unit 750. .

The cell transfer unit 710 is a plurality of cells 20 are transferred in a line. The cell transfer unit 710 may transfer the cell 20 by a belt conveyor method, a walking beam method, and a pickup method. Of course, the cell transfer unit 710 may mix the above-described method for each section to transfer the cell 20. The cell transfer unit 710 is transferred such that two cells 20 per pitch are supplied to the alignment unit 730. At this time, one pitch of the cell transfer unit 710 is set to a movement distance of the length of the two cells 20 are arranged. Since the cell transfer unit 710 supplies two pieces to the alignment unit 730, the transfer speed of the cell transfer unit 710 may be about twice as fast. Therefore, the transfer speed of the cell 20 can be increased.

The tabbing device further includes a dual magazine unit 712 and a dual cell transfer unit 715.

The dual magazine unit 712 positions two cell stacks at the same time to the cell transport unit 710. The cell transfer unit picks up one cell 20 from each cell stack and transfers it to the cell transfer unit 710. Accordingly, since two cells 20 are simultaneously supplied to the cell transfer unit 710, two cells 20 may be supplied to the alignment unit 730 when the cell transfer unit 710 is moved by one pitch.

The cell transfer part 710 is provided with a flux section 713 for applying the flux. Since the flux application device 300 of the flux section 713 sprays the flux to the cell 20 being transported, the process for applying the flux to the cell 20 can be eliminated. Therefore, the transfer speed of the cell 20 can be increased.

A vision section 715 is installed in the cell transfer unit 710, and a vision device is installed in the vision section 715. When the cell transfer unit 710 is moved by one pitch, two cells 20 are introduced into the vision section 715. The vision device reads the position of the cell 20 to determine whether the cell 20 is in a normal position.

The first ribbon transfer unit 720 transfers the ribbon 40. The ribbon 40 is long enough to connect the two cells 20. At this time, the first ribbon transfer unit 720 may simultaneously transfer a set of ribbons 40 so that a plurality of ribbons 40 are connected to the cell 20 in parallel. That is, when the three ribbons 40 are connected to the cell 20 in parallel, three ribbons 40 (one set of ribbons 40) can be simultaneously supplied to the cell 20. When the five ribbons 40 are connected to the cell 20 in parallel, the five ribbons 40 (one set of ribbons 40) can be simultaneously supplied to the cell 20.

In the alignment unit 730, two cells 20 transferred from the cell transfer unit 710 and a set of ribbons 40 transferred from the first ribbon transfer unit 720 are aligned. In the alignment unit 730, the height difference between the preceding cell 20 and the following cell 20 is generated. In addition, the first ribbon transfer unit 720 interposes a set of ribbons 40 between the preceding cell 20 and the succeeding cell 20. At this time, about half of the length of the ribbon 40 is connected to the preceding cell 20, and the cutting degree of the length of the ribbon 40 is connected to the succeeding cell 20. In addition, half of the length of the ribbon 40 is connected to the upper surface of any one of the preceding cell 20 and the following cell 20, and half of the length of the ribbon 40 is among the preceding cell 20 and the following cell 20. It connects to the other bottom. Accordingly, a set of ribbons 40 are simultaneously connected to the preceding cell 20 and the succeeding cell 20 in parallel.

In addition, since the two cells 20 transferred from the cell transfer unit 710 and one set of ribbons 40 transferred from the first ribbon transfer unit 720 are aligned to the alignment unit 730, the cells are moved even if the ribbon transfer unit is moved. No interference is generated between the transfer unit 710 and the ribbon transfer unit.

The cell transfer unit 710 and the alignment unit 730 are connected in series with the conveyor device 400. Therefore, it is possible to suppress the position change when the cell 20 and the ribbon 40 are transferred, and the transfer path of the cell 20 can be shortened.

The cell ribbon transfer unit 740 simultaneously transfers the two cells 20 and the set of ribbons 40 from the alignment unit 730 to the conveyor device 400. Since the cell ribbon transfer unit 740 simultaneously transfers the two cells 20 to the conveyor device 400, the transfer speed of the cells 20 can be increased by about twice. Therefore, the production speed of the cell 20 can be about twice as fast.

The cell ribbon transfer part 740 includes a body 741, a first adsorption head 743, and a second adsorption head 745.

The body 741 is installed to connect the alignment unit 730 and the conveyor device 400. A guide rail portion may be formed on the body 741 along the longitudinal direction. In addition, a drive device such as a linear motor may be installed on the body 741.

The first adsorption head 743 is movably installed on the body 741. For example, the first adsorption head 743 may be moved along the guide rail portion by a driving device such as a linear motor. The first adsorption head 743 simultaneously adsorbs one cell 20 and a set of ribbons 40 at the alignment portion 730.

The second adsorption head 745 is movably installed on the body 741. For example, the second adsorption head 745 may be moved along the guide rail portion by a driving device such as a linear motor. The second adsorption head 745 adsorbs the remaining one cell 20 in the alignment unit 730. The second adsorption head 745 can adsorb the cell 20 almost simultaneously with the first adsorption head 743.

The first adsorption head 743 and the second adsorption head 745 are simultaneously moved along the body 741 to simultaneously supply two cells 20 and a set of ribbons 40 to the conveyor device 400. Since the two cells 20 and one set of ribbons 40 are simultaneously supplied to the conveyor device 400, the transfer speed of the cells 20 can be doubled.

The conveyor device 400 is transported so that two cells 20 per pitch are simultaneously supplied to the heating device 420. Since the conveyor device 400 is moved by a distance corresponding to two cells 20 per pitch, the transfer speed of the conveyor device 400 may be increased by about twice.

The conveyor device 400 is provided with a preheating section 412, two soldering sections 414, and a post heating section 416. Two cells 20 are positioned in each soldering section 414. The heating device 420 is disposed in two soldering sections 414. Since two soldering sections 414 are formed, and two cells 20 are positioned in each soldering section 414, each of the two conveyor cells 400 is soldered to each of the two cells 20 every one pitch movement. It can be transferred to the section 414. For example, when the time for completing the soldering of the cell 20 and the ribbon 40 is approximately 3 seconds, when the conveyor device 400 is moved 1 pitch, the 2 cells 20 are partially in the preceding soldering section 414. Soldering is completed, and the soldering of the two cells 20 is completed in the subsequent soldering section 414 when the conveyor device 400 is moved one pitch further. Therefore, since the soldering speed of the cell 20 becomes the same as the conveying speed of the conveyor device 400, it is possible to make the conveying speed of the conveyor device 400 approximately twice as fast.

35 and 36 are views showing a second embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention. 40 is a view showing an example in which the first embodiment of the pressing device is applied to the tabbing device according to another embodiment of the present invention.

35, 36, and 40, the conveyor device 400 includes a first pressing device 610 and a second pressing device 620.

The first pressurizing device 610 is transferred to the pressurized state of the cell, and then releases pressurization of the cell, and then returns to the home position HP. The second pressurization device 620 is transferred to the pressurized cell alternately with the first pressurization device 610, and then returns to the home position HP after releasing the pressurization of the cell.

Since the first pressurizing device 610 and the second pressurizing device 620 alternately pressurize the cells, the cells are continuously pressed while being transported, and soldered by the heating device 420 while the cells are being moved. Can be. Therefore, the time at which the cell is soldered can be shortened.

The first pressurizing device 610 is transferred to the home position (HP) after releasing the pressurization after one pitch is transferred while the cell is pressurized, and the second pressurizing device 620 alternates with the first pressurizing device 610 It is transferred to the home position (HP) by 1 pitch of the furnace cell under pressure. According to an embodiment of the present invention, two cells 20 are transferred per pitch.

Since the first pressurizing device 610 and the second pressurizing device 620 alternately solder the cells by one pitch, the cells are transported according to the speed at which two cells 20 are simultaneously supplied to the conveyor device 400. I can do it. Therefore, it is possible to reduce the time to stop the cell during the time the cell is soldered in the conveyor device 400.

When the first pressurizing device 610 pressurizes the cell in the home position (HP) and transfers it by one pitch, the second pressurizing device 620 moves to one side of the conveyor device 400 and then returns to the home position (HP) do. At this time, since the second pressing device 620 is located away from the conveyor device 400 so as not to interfere with the first pressing device 610, the movement path of the first pressing device 610 and the second pressing device 620 It is possible to prevent the return path of is arranged at a position that interferes with each other.

In addition, when the second pressing device 620 presses the cell in the home position (HP) and transfers it by one pitch, the first pressing device 610 is moved to one side of the conveyor device 400 and then the home position (HP) Is returned to. At this time, since the first pressing device 610 is located away from the conveyor device 400 so as not to interfere with the second pressing device 620, the movement path of the second pressing device 620 and the first pressing device 610 It is possible to prevent the return path of is arranged at a position that interferes with each other.

The first pressing device 610 and the second pressing device 620 may be disposed to be movable on one side in the width direction of the conveyor device 400. Accordingly, since the first pressing device 610 is moved only on one side in the width direction of the conveyor device 400, the worker is located on the other side in the width direction of the conveyor device 400, and the conveyor device 400 The transfer belt 453 can be replaced. In addition, the conveyor device 400 can be repaired without dismantling the first pressing device 610 or the second pressing device 620.

One of the first pressing device 610 and the second pressing device 620 may return to the home position HP while the cell is moved by one pitch. Therefore, since the first pressing device 610 and the second pressing device 620 are simultaneously moved in the opposite direction by one pitch, the soldering time of the cell can be shortened.

A plurality of pressing pins 611 may be formed in the first pressing device 610 to press the cell. In addition, a plurality of pressing pins 611 may be formed to pressurize the cell in the second pressing device 620. In addition, the pressing pins 611 of the first pressing device 610 and the second pressing device 620 are disposed to be offset from each other.

35 and 36 are views showing a second embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention. 41 is a view showing an example in which a second embodiment of a pressing device is applied to a tabbing device according to another embodiment of the present invention.

35, 36 and 41, the first pressing device 610 and the second pressing device 620 installed in the soldering section 414 of the conveyor device 400 are included.

When the first pressurizing device 610 pressurizes the cell in the home position (HP) and transfers it by one pitch, the second pressurizing device 620 moves to the upper side of the conveyor device 400 and then returns to the home position (HP) do. At this time, since the second pressing device 620 is located above the conveyor device 400 so as not to interfere with the first pressing device 610, the movement path of the first pressing device 610 and the second pressing device 620 ) Can be prevented from being disposed at positions where the return paths interfere with each other.

In addition, when the second pressurizing device 620 presses the cell in the home position (HP) and transfers it by one pitch, the first pressurizing device 610 is moved to the upper side of the conveyor device 400 and then the home position (HP) Is returned to. At this time, since the first pressing device 610 is located above the conveyor device 400 so as not to interfere with the second pressing device 620, the movement path of the second pressing device 620 and the first pressing device 610 ) Can be prevented from being disposed at positions where the return paths interfere with each other.

The first pressing device 610 is moved up and down on one side in the width direction of the conveyor device 400 and is disposed to be movable along the transport direction of the conveyor device 400. In addition, the second pressing device 620 is moved up and down on the other side in the width direction of the conveyor device 400 and is disposed to be movable along the transport direction of the conveyor device 400. Since the first pressurizing device 610 and the second pressurizing device 620 are vertically arranged on both sides of the conveyor, the installation space in the width direction of the conveyor device 400 can be reduced.

One of the first pressing device 610 and the second pressing device 620 may return to the home position HP while the cell is moved by one pitch. Therefore, since the first pressing device 610 and the second pressing device 620 are simultaneously moved in the opposite direction by one pitch, the soldering time of the cell can be shortened.

A plurality of pressing pins 611 may be formed in the first pressing device 610 to press the cell. In addition, a plurality of pressing pins 611 may be formed to pressurize the cell in the second pressing device 620. The pressing pins 611 of the first pressing device 610 and the second pressing device 620 are disposed to be offset from each other.

As described above, since the cells 20 can be supplied and soldered to the conveyor device 400 by two, the production speed of the solar cell module can be increased by about twice. Therefore, production of the solar cell module can be accelerated.

It will be described with respect to the control method of the tabbing device according to an embodiment of the present invention configured as described above.

42 is a flowchart illustrating a method of controlling a soldering device of a tabbing device according to another embodiment of the present invention.

Referring to FIG. 42, in the cell 20 supply device, the dual magazine unit 712 is transferred corresponding to the cell transfer unit 710. Two cell stacks are accommodated in the dual magazine portion 712. The dual cell transfer unit 715 picks up the top layer cell 20 of each cell stack and supplies two cells 20 to the receiving section of the cell transfer unit 710 (S61). Since two cells 20 are supplied to the cell transfer unit 710, the supply speed of the cells 20 can be doubled.

When the cell transfer unit 710 is moved by one pitch, the two cells 20 are moved by the arranged length. Therefore, the transfer speed of the cell 20 is about two times faster.

While the cell 20 is being transported along the cell transfer unit 710, the flux application device 300 applies the flux to the cell 20 (S62). Since the flux is applied to the cell 20 while the cell 20 is being transferred, there is no need to proceed with a separate process to apply the flux to the cell 20. Therefore, the transfer speed of the cell 20 can be increased.

Each time the cell transfer unit 710 is moved by one pitch, two cells 20 are transferred to the vision section 715 (S63). Since the two cells 20 are simultaneously read out in the vision section 715, the transfer speed of the cells 20 can be increased.

As the cell transfer unit 710 is transferred by one pitch, two cells 20 and a set of ribbons 40 are aligned to the alignment unit 730 (S64). At this time, in the alignment unit 730, a height difference between the preceding cell 20 and the following cell 20 is generated. In addition, the first ribbon transfer unit 720 interposes a set of ribbons 40 between the preceding cell 20 and the succeeding cell 20. At this time, about half of the length of the ribbon 40 is connected to the preceding cell 20, and the cutting degree of the length of the ribbon 40 is connected to the succeeding cell 20. In addition, half of the length of the ribbon 40 is connected to the upper surface of any one of the preceding cell 20 and the following cell 20, and half of the length of the ribbon 40 is among the preceding cell 20 and the following cell 20. It connects to the other bottom. Accordingly, a set of ribbons 40 are simultaneously connected to the preceding cell 20 and the succeeding cell 20 in parallel.

Two cells 20 and a set of ribbons 40 located in the alignment unit 730 are transferred to the conveyor device 400 by the cell ribbon transfer unit 740 (S65). At this time, one cell 20 and one set of ribbons 40 are simultaneously adsorbed by the first adsorption head 743 alignment unit 730, and the second adsorption head 745 is the remaining 1 at the alignment unit 730. Two cells 20 are adsorbed. The second adsorption head 745 can adsorb the cell 20 almost simultaneously with the first adsorption head 743. The first adsorption head 743 and the second adsorption head 745 are simultaneously moved along the body 741 to simultaneously supply two cells 20 and a set of ribbons 40 to the conveyor device 400. Since the two cells 20 and one set of ribbons 40 are simultaneously supplied to the conveyor device 400, the transfer speed of the cells 20 can be doubled.

The second ribbon transfer unit 750 further connects the ribbon 40 to the trailing cell 20 of the conveyor device 400 (S66). At this time, the ribbon 40 is stacked on the trailing cell 20 located in the conveyor device 400. The conveyor device 400 drives the vacuum device 430 to suck air. The cell 20 and the ribbon 40 are adsorbed by the vacuum pressure to the transfer belt 453 by the vacuum device 430 sucking air.

When the conveyor device 400 moves one pitch, two cells 20 are supplied to the soldering section 414 (S67). At this time, in the preceding soldering section 414, two cells 20 are simultaneously heated for approximately half the soldering time. In the preceding soldering section 414, the cell 20 is partially soldered.

When the conveyor device 400 moves one pitch further, two cells 20 are supplied to the following soldering section 414. In the subsequent soldering section 414, two cells 20 are simultaneously soldered for approximately half the soldering time. In the subsequent soldering section 414, soldering is completed (S68). Since two soldering sections 414 are formed, and two cells 20 are positioned in each soldering section 414, each of the two conveyor cells 400 is soldered to each of the two cells 20 every one pitch movement. It can be transferred to the section 414.

As described above, since the transfer speed and the soldering speed of the cell 20 are about twice as fast, the production of the solar cell module can be accelerated.

Next, a tabbing device according to another embodiment of the present invention will be described in detail with reference to the drawings.

43 is a view showing a tabbing device according to another embodiment of the present invention. 44 is a view showing a stacked form of a cell and a ribbon in a tabbing device according to another embodiment of the present invention. 45 is a view showing a first embodiment of a cell ribbon transfer part in a tabbing device according to another embodiment of the present invention. 46 is a view showing a second embodiment of the cell ribbon transfer unit in the tabbing device according to another embodiment of the present invention. 47 is a view showing a third embodiment of the cell ribbon transfer unit in the tabbing device according to another embodiment of the present invention.

43 to 47, a cell transfer unit 810, a ribbon transfer unit 820, an alignment unit 830, and a cell ribbon transfer unit 840 are included.

In the cell transfer unit 810, a plurality of cells 20 are transferred in a line. The cell transfer unit 810 may transfer the cell 20 by a belt conveyor method, a walking beam method, and a pickup method. Of course, the cell transfer unit 810 may also transfer the cells 20 by mixing the above methods for each section. The cell transfer unit 810 is transferred such that one cell 20 per pitch is supplied to the alignment unit 830. At this time, one pitch of the cell transfer unit 810 is set to a movement distance of the length of one cell 20 is arranged.

In the cell transfer part 810, a flux section 813 for applying the flux is disposed. In the flux section 813, since the flux is injected into the cell 20 being transported, a process for applying the flux to the cell 20 can be eliminated. Therefore, the transfer speed of the cell 20 can be increased.

A vision section 815 is installed in the cell transfer unit 810, and a vision device is installed in the vision section 815. When the cell transfer unit 810 is moved by one pitch, one cell 20 is introduced into the vision section 815. The vision device reads the position of the cell 20 to determine whether the cell 20 is in a normal position.

The ribbon transfer unit 820 transfers the ribbon 40. The ribbon 40 is long enough to connect the two cells 20. At this time, the ribbon transfer unit 820 may simultaneously transfer a set of ribbons 40 to connect the plurality of ribbons 40 to the cell 20 in parallel. That is, when the three ribbons 40 are connected to the cell 20 in parallel, three ribbons 40 (one set of ribbons 40) can be simultaneously supplied to the cell 20. When the five ribbons 40 are connected to the cell 20 in parallel, the five ribbons 40 (one set of ribbons 40) can be simultaneously supplied to the cell 20.

In the alignment unit 830, one cell 20 transferred from the cell transfer unit 810 and one set of ribbons 40 transferred from the ribbon transfer unit are aligned. In the alignment part 830, the ribbon 40 is arranged in a state in which about half of the length of the ribbon 40 is stacked on the cell 20. In addition, the cell 20 does not correspond to about half the length of the ribbon 40. The length of the alignment part 830 may be formed to be longer than the length of the ribbon 40.

A plurality of cell transfer units 810 are disposed, and an alignment unit 830 is disposed for each cell transfer unit 810. Therefore, in each cell transfer unit 810, the cell 20 is transferred in units of one pitch, but overall, the transfer speed of the cell 20 may be increased by the number of cell transfer units 810.

The plurality of cell transfer parts 810 may be arranged side by side. Since the plurality of cell transfer parts 810 are arranged side by side, the transfer section of the cell 20 can be shortened. In addition, since the transport path of the cell 20 is formed in a straight path, the movement of the position of the cell 20 can be suppressed.

The plurality of cell transfer parts 810 are connected in parallel to the conveyor device 400. Since a plurality of cell transfer parts 810 are connected in parallel, the path for transferring the cell 20 and the ribbon 40 from the alignment part 830 to the conveyor device 400 by the cell ribbon transfer part 840 is simple and short. Can form.

At this time, a ribbon transfer unit may be disposed on one side of each cell transfer unit 810. The ribbon transfer unit 820 supplies one ribbon 40 each time the cell 20 reaches the corresponding alignment unit 830.

The cell ribbon transfer unit 840 simultaneously transfers the cell 20 and the ribbon 40 of the alignment unit 830 to the conveyor device 400. Since the cell 20 and the ribbon 40 are simultaneously transferred to the conveyor device 400, when transferring the cell 20 and the ribbon 40 to the conveyor device 400, the cell ribbon transfer unit 840 and the ribbon transfer unit Interference can be prevented. In addition, since the cell 20 and the ribbon 40 are simultaneously supplied to the transport conveyor device 400, the transport speed of the conveyor device 400 can be increased by about twice. That is, conventionally, the cell 20 transfer unit supplies the cell 20 to the conveyor device 400 and returns to the original position, and then the ribbon transfer unit stacks the ribbon 40 on the cell 20 and returns to the original position. , The conveyor device 400 was conveyed 1 pitch. However, according to the present invention, since the cell 20 and the ribbon 40 of the alignment unit 830 are simultaneously transported to the conveyor device 400, the transport speed of the conveyor device 400 may be increased.

At this time, the cell transfer unit 810 supplies one cell 20 for each pitch to the alignment unit 830, and the ribbon transfer unit 820 aligns one set of ribbons 40 for each pitch by the alignment unit 830. To supply. The ribbon transfer unit 820 may supply a set of ribbons 40 to the alignment unit 830 during a stopped time after the cell transfer unit 810 is transferred by one pitch. Therefore, the time for supplying the ribbon 40 to the alignment unit 830 does not affect the decrease in the transfer speed of the cell transfer unit 810.

The cell ribbon transfer unit 840 rotates once in the plurality of alignment units 830 to simultaneously adsorb the cell 20 and the ribbon 40 and transfer them to the conveyor device 400. Therefore, as the supply speed of the cell 20 and the ribbon 40 to the conveyor device 400 increases, the cell 20 can be transferred at a high speed.

The cell ribbon transfer part 840 adsorbs the cell 20 from the aligning part 830, and the cell adsorbing part 843 adsorbing the ribbon 40 from the aligning part 830, and the cell adsorbing part 843. It includes a ribbon adsorption unit 845 that is transferred to the conveyor device 400 together. The cell adsorption unit 843 and the ribbon adsorption unit 845 are simultaneously moved to supply one cell 20 and a set of ribbons 40 to the conveyor device 400.

The cell ribbon transfer part 840 may include a pipe-shaped cell adsorption portion 843 and a pipe-shaped ribbon adsorption portion 845 as illustrated in FIG. 45. In addition, the cell ribbon transfer part 840 may include a cell adsorption portion 843 in the form of a square plate and a ribbon adsorption portion 845 in the form of a pipe, as shown in FIG. 46. In addition, as shown in FIG. 46, the cell ribbon transfer part 840 may include a cell adsorption portion 843 in the form of an erected square plate and a ribbon adsorption portion 845 in the form of a pipe. As illustrated in FIG. 47, the cell ribbon transfer unit 840 may include a cell adsorption unit 843 in the form of a square plate that is in surface contact with the cell 20 and a ribbon adsorption unit 845 in the form of a pipe. . The shape of the cell ribbon transfer part 840 may be variously changed.

The conveyor device 400 is provided with a preheating section 412, a plurality of soldering sections 414, and a post-heating section. A heating device 420 is installed in the soldering section 414. Each time the conveyor device 400 moves one pitch, one cell 20 is supplied to each of the plurality of soldering sections 414. For example, when the time for completing the soldering of the cell 20 and the ribbon 40 is approximately 3 seconds, and when 3 soldering sections 414 are installed, the cell 20 is moved by one pitch per second to make the last soldering section. Soldering is completed at 414. Therefore, when the conveyor device 400 is conveyed in pitch units, three cells 20 are soldered little by little in three soldering sections 414, so that the cells 20 are soldered one per second as a whole. Therefore, the soldering time can be shortened.

32 and 33 are views showing a first embodiment of a pressing device in a soldering device of a tabbing device according to an embodiment of the present invention. 48 is a view showing an example in which the first embodiment of the pressing device is applied to the tabbing device according to another embodiment of the present invention.

32, 33 and 48, the conveyor device 400 includes a first pressing device 610 and a second pressing device 620.

The first pressing device 610 is transferred in a state in which the soldering object is pressed, and then releases the pressing of the soldering object, and then returns to the home position HP. The second pressurizing device 620 is transferred to the pressurized object alternately with the first pressurizing device 610, and then releases pressurization of the soldering object and then returns to the home position HP.

Since the first pressing device 610 and the second pressing device 620 alternately transfer the soldering object in a pressurized state, the soldering object is continuously pressed while being transferred, and the heating device 420 while the soldering object is being moved It can be soldered by. Therefore, the time during which the object to be soldered is soldered can be shortened.

The first pressing device 610 is transported 1 pitch in a state in which the soldering object is pressed and then released to the home position HP after releasing the pressing, and the second pressing device 620 is provided with the first pressing device 610. Alternately, the object to be soldered is conveyed 1 pitch in a pressurized state, and then returned to the home position (HP). According to an embodiment of the present invention, one cell 20 and a set of ribbons 40 are transferred per pitch.

Since the first pressing device 610 and the second pressing device 620 alternately solder the object to be soldered by one pitch, the soldering object is transferred to the conveyor device 400 according to the speed at which the cells 20 are simultaneously supplied. I can do it. Therefore, it is possible to reduce the time to stop the soldering object during the time during which the soldering object is soldered in the conveyor device 400.

When the first pressing device 610 presses the soldering object in the home position (HP) and transfers it by one pitch, the second pressing device 620 moves to one side of the conveyor device 400 and then returns to the home position (HP). Will return. At this time, since the second pressing device 620 is located away from the conveyor device 400 so as not to interfere with the first pressing device 610, the movement path of the first pressing device 610 and the second pressing device 620 It is possible to prevent the return path of is arranged at a position that interferes with each other.

In addition, when the second pressing device 620 presses the object to be soldered at the home position (HP) and conveys it by one pitch, the first pressing device 610 is moved to one side of the conveyor device 400, and then the home position (HP ). At this time, since the first pressing device 610 is located away from the conveyor device 400 so as not to interfere with the second pressing device 620, the movement path of the second pressing device 620 and the first pressing device 610 It is possible to prevent the return path of is arranged at a position that interferes with each other.

The first pressing device 610 and the second pressing device 620 may be disposed to be movable on one side in the width direction of the conveyor device 400. Therefore, since the first pressing device 610 is moved only on one side in the width direction of the conveyor device 400, the second pressing device 620 is located on the other side in the width direction of the conveyor device 400, so that the conveyor device 400 The transfer belt 453 can be replaced. In addition, the conveyor device 400 can be repaired without dismantling the first pressing device 610 or the second pressing device 620.

Any one of the first pressing device 610 and the second pressing device 620 may be returned to the home position HP while the object to be soldered is moved one pitch. Therefore, since the first pressing device 610 and the second pressing device 620 are simultaneously moved in the opposite direction by one pitch, it is possible to shorten the soldering time of the object to be soldered.

A plurality of pressing pins 611 may be formed on the first pressing device 610 to press the soldering object. In addition, a plurality of pressing pins 611 may be formed in the second pressing device 620 to press the soldering object. In addition, the pressing pins 611 of the first pressing device 610 and the second pressing device 620 are disposed to be offset from each other.

35 and 36 are views showing a second embodiment of the pressing device in the soldering device of the tabbing device according to an embodiment of the present invention. 49 is a view showing an example in which a second embodiment of a pressing device is applied to a tabbing device according to another embodiment of the present invention.

35, 36 and 49, the first pressing device 610 and the second pressing device 620 installed in the soldering section 414 of the conveyor device 400 are included.

When the first pressing device 610 presses the object to be soldered at the home position (HP) by one pitch, the second pressing device 620 moves to the upper side of the conveyor device 400 and then moves to the home position (HP). Will return. At this time, since the second pressing device 620 is located above the conveyor device 400 so as not to interfere with the first pressing device 610, the movement path of the first pressing device 610 and the second pressing device 620 ) Can be prevented from being disposed at positions where the return paths interfere with each other.

In addition, when the second pressing device 620 presses the object to be soldered at the home position (HP) by one pitch, the first pressing device 610 is moved to the upper side of the conveyor device 400 and then moves to the home position (HP ). At this time, since the first pressing device 610 is located above the conveyor device 400 so as not to interfere with the second pressing device 620, the movement path of the second pressing device 620 and the first pressing device 610 ) Can be prevented from being disposed at positions where the return paths interfere with each other.

The first pressing device 610 is moved up and down on one side in the width direction of the conveyor device 400 and is disposed to be movable along the transport direction of the conveyor device 400. In addition, the second pressing device 620 is moved up and down on the other side in the width direction of the conveyor device 400 and is disposed to be movable along the transport direction of the conveyor device 400. Since the first pressurizing device 610 and the second pressurizing device 620 are vertically arranged on both sides of the conveyor, the installation space in the width direction of the conveyor device 400 can be reduced.

Any one of the first pressing device 610 and the second pressing device 620 may be returned to the home position HP while the object to be soldered is moved one pitch. Therefore, since the first pressing device 610 and the second pressing device 620 are simultaneously moved in the opposite direction by one pitch, it is possible to shorten the soldering time of the object to be soldered.

As described above, since the cell 20 and the ribbon 40 are simultaneously supplied to the conveyor device 400 and the cell 20 is soldered in a plurality of soldering sections 414, the production speed of the solar cell module can be made faster. Can. Therefore, production of the solar cell module can be accelerated.

It will be described with respect to the control method of the tabbing device according to an embodiment of the present invention configured as described above.

50 is a flowchart illustrating a method of controlling a tabbing device according to another embodiment of the present invention.

Referring to FIG. 50, the magazine is transferred from the cell supply device 100 to correspond to the cell transfer unit 810. The cell stack is accommodated in the magazine unit 110. The cell 20 transfer unit picks up the cell 20 of the uppermost layer of the cell stack, and supplies one cell 20 to each cell in the receiving section of the cell transfer unit 810 (S71). The cell transfer unit 810 is moved by the length of the cell 20 when moved one pitch.

While the cell 20 is being transported along the cell transfer unit 810, the flux application device 300 applies the flux to the cell 20 (S72). Since the flux is applied to the cell 20 while the cell 20 is being transported, there is no need to go through a separate process to apply the flux to the cell 20. Therefore, the transfer speed of the cell 20 can be increased.

Each time the cell transfer unit 810 is moved by one pitch, one cell 20 is transferred to the vision section 815 (S73). Since the vision device reads the position of the cell 20 in the vision section 815, it is possible to accurately determine the position of the cell 20.

One cell 20 and a set of ribbons 40 are aligned to the alignment unit 830 as the cell transport unit 810 is transferred by one pitch (S74). At this time, in the alignment portion 830, the ribbon 40 is arranged in a state in which about half of the length of the ribbon 40 is stacked on the cell 20. The ribbon transfer unit 820 may supply the ribbon 40 to the alignment unit 830 while the cell transfer unit 810 is stopped after one pitch transfer. Therefore, it is possible to prevent the time when the ribbon 40 is supplied to the alignment unit 830 affecting the speed of the cell 20 lowering.

One cell 20 and a set of ribbons 40 positioned in the alignment unit 830 are transferred to the conveyor device 400 by the cell ribbon transfer unit 840 (S75). At this time, the cell adsorption unit 843 simultaneously adsorbs one cell 20 and a set of ribbons 40 from the alignment unit 830, and the cell adsorption unit 8831 is simultaneously moved along the body 841. One cell 20 and a set of ribbons 40 are simultaneously supplied to the conveyor device 400. Since one cell 20 and one set of ribbons 40 are supplied to the conveyor device 400 at the same time, the transfer speed of the cell 20 can be doubled.

In addition, the cell ribbon transfer unit 840 rotates once in the plurality of alignment units 830 to simultaneously adsorb the cell 20 and the ribbon 40 and transfer them to the conveyor device 400. Accordingly, as the speed at which the cells 20 and the ribbons 40 are supplied to the conveyor device 400 increases, the cells 20 can be transferred at a high speed.

As the conveyor device 400 supplies one cell 20 to each of the plurality of soldering sections 414 per pitch, soldering is completed (S76). For example, when the time for completing the soldering of the cell 20 and the ribbon 40 is approximately 3 seconds, and when 3 soldering sections 414 are installed, the cell 20 is moved by one pitch per second to make the last soldering section. Soldering is completed at 414. Therefore, when the conveyor device 400 is conveyed in pitch units, three cells 20 are soldered little by little in three soldering sections 414, so that the cells 20 are soldered one per second as a whole. Therefore, the soldering time can be shortened.

As described above, since the cell 20 and the ribbon 40 are simultaneously supplied to the conveyor device 400 and the cell 20 is soldered in a plurality of soldering sections 414, the production speed of the solar cell module can be made faster. Can. Therefore, production of the solar cell module can be accelerated.

Next, a first embodiment of a cell transfer device in a tabbing device according to an embodiment of the present invention will be described with reference to the drawings.

51 is a view showing a first embodiment of a cell transfer device in a tabbing device according to an embodiment of the present invention.

The vision unit 913 reads the cell 20 transferred from the cell receiving unit 911. The vision unit 913 includes a vision camera 914. The vision unit 913 determines the location of the cell 20 by comparing the read image of the cell 20 with a reference image.

The cell 20 read from the vision unit 913 is transferred to the alignment unit 915. The alignment unit 915 aligns the cells 20 by the difference between the read image and the reference image. When the cell 20 of the vision unit 913 is seated on the alignment unit 915, it may be aligned. Since the cell 20 is aligned to the alignment part 915 at the same time, time required for aligning the cell 20 can be saved.

Is made in Accordingly, it is possible to prevent devices that receive, read, and align the cell 20 from interfering with each other, thereby eliminating the waiting time for operation of the devices. For example, in the related art, after the cell 20 was transferred from the cell receiving unit 911 to the vision unit 913, the vision inspection had to be waited until the transfer device left the vision unit 913. In addition, when the vision inspection is completed in the vision unit 913, the transfer device discharges the cell 20 from the vision unit 913, and until the cell 20 is transferred back to the vision unit 913 in the receiving unit. It was necessary to wait for the vision inspection of the Vision Department (913). However, according to the present invention, since devices that receive, read, and align the cell 20 can be prevented from interfering with each other, it is possible to eliminate an operation waiting time of the devices. Therefore, by reducing the tact time of the cell 20, the production of the cell 20 can be accelerated.

The rotating stage 923 is rotated by a predetermined angle to correspond to the transfer time of the cell 20. For example, when the cell receiving unit 911, the vision unit 913, and the aligning unit 915 are arranged to form a 90° interval around the rotation axis of the rotation stage 923, the cell 20 moves 1 pitch. When the rotation stage 923 is rotated by 90 degrees. Therefore, as the rotating stage 923 is rotated, the cell 20 is continuously supplied to the vision unit 913, so that it is possible to prevent devices from interfering or being placed in a standby state in each section.

The cell transfer device 900 further includes a cell transfer machine 931 and a cell ejector 933.

The cell transfer machine 931 is installed to pick up the cell 20 of the magazine and transfer it to the cell receiving unit 911.

Therefore, it is possible to prevent devices from interfering or being placed in a standby state in each section.

A third embodiment of the cell transfer device in the tabbing device according to an embodiment of the present invention will be described with reference to the drawings. Since the third embodiment is substantially the same as the first embodiment except for the cell transfer unit 710, the same reference numerals will be assigned to the same configuration as the first embodiment and the description thereof will be omitted.

54 and 55 are views showing a third embodiment of the cell transfer device in the tabbing device according to an embodiment of the present invention.

Referring to FIGS. 54 and 55, the cell transfer unit 915 moves from the cell receiving unit 911, the vision unit 913, and the alignment unit 915 in the vertical direction and the transport direction of the cell 20 as the cell ( 20) may be a working beam 925 for transferring. For example, the walking beam 925 increases the cell 20 of the cell receiving unit 911 by a predetermined height and then moves in one pitch transfer direction, and after being moved by one pitch, the cell is moved to the vision unit 913 as it descends. Seat (20). The walking beam 925 located in the vision unit 913 returns to the original position. As the process is continuously repeated, the cells 20 are transferred by one pitch every predetermined time. As such, as the working beam 925 is driven, the cell 20 is continuously supplied to the vision unit 913, so that it is possible to prevent devices from interfering or being placed in a standby state in each section.

The cell transfer device 900 further includes a cell transfer machine 931 and a cell ejector 933.

By transferring, it is possible to prevent the vision area of the vision unit 913 from being interfered by various devices. Therefore, it is possible to prevent devices from interfering or being placed in a standby state in each section.

The control method of the cell transfer device according to the embodiment of the present invention configured as described above will be described.

56 is a flowchart illustrating a method of controlling a cell transfer device in a tabbing device according to an embodiment of the present invention.

Referring to FIG. 56, the cell transfer machine 931 picks up the uppermost cell 20 from the cell stack of the magazine and seats it in the cell receiving unit 911. The cell 20 is transferred to the vision unit 913 by the cell transfer unit 920 (S81). At this time, if the cell transfer unit 920 is a belt conveyor 921, the cell 20 is transferred to the vision unit 913 as the belt conveyor 921 is moved one pitch. In addition, when the cell transfer unit 920 is the rotation stage 923, the cell 20 is transferred to the vision unit 913 as the rotation stage 923 is rotated 90 degrees. When the cell transfer unit 920 is the working beam 925, the working beam 925 is raised and then transferred along the transport direction of the 1-pitch cell 20, and when the working beam 925 descends, the cell 20 is moved. It is transferred to the vision unit 913. The working beam 925 is returned to its original position in a descending state.

The vision unit 913 vision-checks the cell 20 to read the position of the cell 20. The position of the cell 20 is calculated by comparing the vision measurement value with the reference value. While the cell 20 is being transferred to the alignment unit 915, the position of the cell 20 is calculated by comparing this vision measurement value with a reference value (S82). Since the vision measurement value and the reference value are calculated while the cell 20 is being transported, it is possible to prevent a waiting time for calculation when the cell 20 is aligned. In addition, as shown in the second column of FIG. 56, the cell transfer machine 931 picks up the uppermost cell 20 from the cell stack of the magazine part and seats it on the cell receiving part 911.

In addition, the vision unit 913 vision-checks the cell 20 to read the position of the cell 20. The position of the cell 20 is calculated by comparing the vision measurement value with the reference value. While the cell 20 is being transferred to the alignment unit 915, the position of the cell 20 is calculated by comparing this vision measurement value with a reference value. The cell transfer machine 931 picks up the top layer cell 20 from the cell stack of the magazine and seats it in the cell receiver 911. The cell 20 is transferred to the vision unit 913 by the cell transfer unit 920 (S83).

As described above, since the devices are not interfered with in the cell receiving unit 911, the vision unit 913, and the alignment unit 915, cell 20 receiving, vision inspection, and cell 20 discharge may be simultaneously performed. Furthermore, since the standby time of the device can be reduced, the production speed of the solar cell module can be increased.
