Referring to Figure 3 and 4 will be described in detail such a process as follows.

<S1: Loading the components of the solar cell module in the loading unit 100>

First, the filler 122 and / or the back sheet 172, which are components of the solar cell module, are prepared in the form of rolls wound on the rollers 125 and 175 of the filler supply unit 120 and / or the back sheet supply unit 170, and The battery 132 and the glass plate 142 are prepared by stacking a plurality of spaced apart pieces individually in the receiving region in the chain belt of the solar cell supply unit 130 and the glass plate supply unit 140 (S0).

Then, the arm 160 coupled to the gantry 150 of the loading part 100 is moved to the point A, and then the solar cell 132 is absorbed by the adsorption plate 166 of the arm 160. Then, when the arm 160 is moved in the longitudinal direction of the horizontal beam 152 to reach the point B corresponding to the central position of the upper surface of the support 110, the solar cell 132 is detached from the adsorption plate 166 to the center of the upper surface. Settle down.

Then, the rollers 125 of the filler supply unit 120 are driven to stack the fillers 122 directly on the upper surface of the solar cell 132 previously seated on the upper surface of the support 110, and then provided on the upper surface of the support 110. The gripper 112 is used. The filler 122 is cut by the cutter 162 of the arm 160 while moving the arm 160 coupled to the gantry 150 in the longitudinal direction of the horizontal beam 152.

Finally, the arm 160 coupled to the gantry portion 150 is moved to point C, and then the uppermost glass plate 142 is adsorbed from the glass plate supply unit 140 to the adsorption plate 166 of the arm 160. Then, when the arm 160 is moved in the longitudinal direction of the horizontal beam 152 to reach the point B corresponding to the central position of the upper surface of the support 110, the glass plate 142 is detached from the suction plate 166 to fill the lower filler ( 122) to be stacked on.

By going through this process, the lamination of the solar cell module components (laminating object) is completed and positioned on the upper surface of the support 110.

After the solar cell 132 and the glass plate 142 of the uppermost accommodating region in the chain belt of the solar cell supply unit 130 and the glass plate supply unit 140 are used, each of the chain belts 135a and 135b forming a pair; 145a and 145b rotate in the counterclockwise-clockwise direction to move the solar cell 132 and the glass plate 142 upwards. As a result, the solar cell 132 and the glass plate 142 that can be used reside in the uppermost portion of the chain belt of the solar cell supply unit 130 and the glass plate supply unit 140, respectively.

Of course, the lamination order may be glass plate-> filler-> solar cell, and when the back sheet is used, the lamination order is glass plate-> filler-> solar cell-> filler-> back sheet or back sheet-> filler- > Solar cell-> filler-> glass plate may be used.

<S2: Step of Laminating Stacked Solar Cell Module Components>

The laminating object transferred to the laminator unit 200 is arranged on the heater platen 228 in the lower chamber 226 of the laminator 220 by means of a conveying means (not shown) such as a Teflon belt. In this case, the laminating object may be set using an alignment jig for precise setting and arrangement, and may be disposed in the center of the heater platen 228 and then the jig may be separated and arranged.

Then, the upper cover 224 of the laminator 220 is closed, and the vacuum pump 240 is operated to make a space between the upper cover 224 and the rubber plate 225 in a vacuum state and the rubber plate 225 to the upper cover. (224) to the inner surface.

At this time, the temperature inside the chamber of the laminator 220 is approximately room temperature ~ 200 ℃, preferably about 120 ℃ by the heater platoon 228. The internal temperature is controlled by the PID temperature automatic control device, and the temperature is shut off when overheated.

Then, the inner space of the lower chamber 226 also operates the vacuum pump 240 to make a vacuum to remove bubbles and the like generated in the solar cell module.

In the next step, the inner space of the lower chamber 226 is supplied with compressed air through the pressure port 224b of the upper cover 224 of the laminator 220 while maintaining the vacuum state. The rubber plate 225 is expanded by the supplied compressed air, and the laminating object is pressurized to a constant pressure by the expansion pressure of the rubber plate. The laminating object is fused by the pressing force and the heating temperature of the heater platoon 228 and the filler 122 interposed between the stacked solar cell module components.

At this time, in order to widen the pressure generating area by the compressed air to the maximum and to ensure that the lower expansion pressure of the rubber plate 225 is constant at each part of the laminating object, the air hole 224a communicates with the inner surface of the upper cover 224. It is preferable to distribute the vacuum flow path 224c.

Then, the supplied compressed air is discharged to make a space between the upper cover 224 and the rubber plate 225 in a vacuum state, and air is communicated inside the lower chamber 226 to remove the vacuum state. At this time, the expanded rubber plate 225 is fed back to the original state, the temperature inside the laminator 220 is lowered to approximately 80 ℃.

Then, the air is communicated between the upper cover 224 and the rubber plate 225 to remove the vacuum state, and the heat of the heater platen 228 and the inside of the lower chamber 226 of the laminator 220 is removed for about 1 minute. Perform a water cooling operation to cool down the temperature to approximately 50 ~ 80 ℃.

When the process is completed, the upper cover 224 of the laminator 220 is opened.

The laminating completed solar cell module is transferred to the unloading part 300 by a transfer means (not shown) such as a Teflon belt, a conveyor belt, a robot, and a grip means controlled through an external operation of the controller or a built-in sensor.

<S3: step of loading the solar cell module lamination is completed in the loading section 300>

The lamination completed solar cell module transferred to the loading and unloading unit 300 by the above-described transfer means is transferred to a central position of the upper surface of the support 310 by a separate transfer means provided with a Teflon belt.

When the solar cell module 332 is transferred to the upper surface of the support 310, the arm 366 is moved along the horizontal beam 352 of the gantry 350 to a central position, and the suction plate 366 of the arm 360 is moved. Adsorb the completed solar cell module 332 by the). Then, when the arm 366 reaches the horizontal beam 352 in the longitudinal direction to reach the solar cell module accommodating part 330 disposed on the side of the support part 310, the solar cell module is detached from the suction plate 366. The battery module accommodating part 330 is stacked in a single spaced apart manner within the accommodating area in the chain belt.

When the solar cell module is seated in the uppermost receiving area of the solar cell module accommodating part 330, the pair of chain belts 335a and 335b rotate in a clockwise-counterclockwise direction to move the solar cell module downward. As a result, an acceptable empty space area is continuously formed at the top of the solar cell module accommodating part 320.

The solar cell module manufacturing process using the automatic laminator system may be continuously performed based on the time required in each manufacturing process.
