On the other hand, the operation of the plate bonding device 100 will be described in detail below.

FIG. 6 is an operation view showing a first operation of the plate bonding device 100 shown in FIG. 1. Hereinafter, the same reference numerals as the above-described reference numerals denote the same members.

Referring to FIG. 6, the user may arrange the first plate D on the seating stage 110. In this case, the first plate (D) should be placed at the correct position of the mounting stage 110, and if not positioned at the correct position as described above, the mounting stage 110 may be moved or rotated to align the positions.

When the above process is completed, the third height adjustment unit 140 may rise. At this time, when the third height adjustment unit 140 is raised, the departure prevention unit 160 and the fall prevention unit 150 may operate. In this case, the third height adjusting unit 140 may be disposed to face the roller 170 to raise one end of the first plate D to a predetermined height.

In addition, when the third height adjusting part 140 is raised, the first height adjusting part 120 and the second height adjusting part 130 may also operate to support the first plate D. FIG. In detail, when the third height adjustment unit 140 operates, the separation prevention unit 160 may operate. At this time, the departure prevention driving unit 161 may operate to vary the position of the departure prevention plate 162. For example, the anti-separation driving unit 161 may operate so that the anti-separation plate 162 moves in the longitudinal direction of the first plate D with respect to the third height adjusting unit 140.

When the operation as described above the departure prevention plate 162 is in contact with one surface of the first plate (D) located in the upper side of FIG. Therefore, the departure prevention plate 162 may prevent the first plate (D) to move to the upper side of FIG.

While the above process is in progress, the fall prevention unit 150 may also operate. In this case, the fall prevention plate 152 may move in the longitudinal direction of the first plate D based on the third height adjusting unit 140 according to the operation of the fall prevention driving unit 151.

In detail, when the fall prevention driving unit 151 operates, the fall prevention plate 152 may contact the other surface of the first plate D located at the lower side of FIG. 6. Therefore, the fall prevention plate 152 may prevent the first plate (D) from falling by supporting the other surface of the first plate (D).

In addition, the position of the fall prevention plate 152 may vary depending on the degree of operation of the roller 170. Specifically, the fall prevention plate 152 may raise the one end of the first plate (D) by operating the third height adjustment unit 140 when the roller 170 is located at the initial position.

At this time, the fall prevention plate 152 may move in the longitudinal direction of the first plate (D) on the basis of the third height adjusting unit 140. That is, the fall prevention plate 152 may protrude from the third height adjusting part 140 to move toward the longitudinal direction of the first plate D.

In particular, the fall prevention plate 152 may vary in position depending on the height of one end of the first plate (D). For example, the fall prevention plate 152 may further protrude from the third height adjusting part 140 side to the first plate D as the first plate D moves away from the seating stage 110.

On the other hand, the fall prevention plate 152 is the third from the first plate (D) side when the first plate (D) closer to the seating stage 110, that is, the height of one end of the first plate (D) is lowered It may be further introduced into the height adjustment unit 140 side.

Therefore, as described above, when the third height adjusting part 140 raises the height of one end of the first plate D, the fall preventing plate 152 protrudes from the third height adjusting part 140 to Can support one end.

Meanwhile, the roller 170 may move toward the first plate D while the above process is performed. Specifically, the roller driving unit (not shown) may operate to move the roller 170 such that the surface of the roller 170 is in linear contact with one surface of the first plate D.

In addition, the first height adjustment unit 120 and the second height adjustment unit 130 may operate while the above process is in progress. In detail, when the first height adjusting part 120 operates, the first height variable part 121 may operate to move the first support part 122 and the first buffer member 123. In particular, when the first height adjustment unit 120 operates, the first support part 122 and the first buffer member 123 may move to the upper side of FIG. 6. In this case, the first buffer member 123 may move to the upper side of FIG. 6 to be in contact with the other surface of the first plate D. FIG.

When the second height adjustment unit 130 operates, the second height variable unit 131 may operate to move the second support part 132 and the second buffer member 135. In particular, the second bracket 133 and the second protrusion 134 may move to the upper side of FIG. 6 according to the operation of the second height variable portion 131. At this time, the second shock absorbing member 135 may contact the other surface of the first plate D due to the rise of the second bracket 133 and the second protrusion 134.

On the other hand, when operating as described above, the height of the first height adjusting unit 120 and the second height adjusting unit 130 may be formed differently. Specifically, the height of the first height adjusting unit 120 may be formed lower than the height of the second height adjusting unit 130. For example, the height of the first buffer member 123 may be lower than the height of the second buffer member 135. Accordingly, when the first height adjusting part 120 and the second height adjusting part 130 are controlled as described above, the first plate D is disposed diagonally from the third height adjusting part 140 to the roller 170. Can be.

As described above, when the first plate D is disposed diagonally, the second bracket 133 may rotate the second height variable part 131. In detail, the second bracket 133 may have a variable position so as to correspond to an oblique line of the first plate D. FIG.

At this time, when the second bracket 133 is rotated, the second protrusion 134 may be disposed in an oblique direction of the first plate (D). In particular, when a plurality of second protrusions 134 are provided, the plurality of second protrusions 134 may be disposed at different heights.

In addition, the plurality of second shock absorbing members 135 installed on the plurality of second protrusions 134 may support curved surfaces of the first plate D, respectively. In this case, the plurality of second buffer members 135 may be disposed at the same position as the plurality of second protrusions 134 to support the first plate D as described above. Accordingly, even when the first plate D is inclined as described above, the load of the inclined first plate D may be distributed and supported through the second buffer member 135.

As described above, when the second bracket 133 rotates by a predetermined angle, the rotation angle of the second bracket 133 may be limited by the stopper part 136. In detail, when the second bracket 133 rotates and rotates by a predetermined angle, the second bracket 133 may not be rotated any further by contacting the stopper part 136 formed at one end of the second height variable part 131. Therefore, since the second bracket 133 is fixed by the stopper part 136, the second bracket 133 is no longer rotated by the weight of the first plate D, and the second plate 133 can effectively support the first plate D.

Meanwhile, after the first plate D is raised as described above, the second plate may be disposed on the seating stage 110. At this time, the size of the first plate (D) is larger than the second plate is formed so that the first height adjusting part 120, the second height adjusting part 130, the fall prevention part 150 and the departure prevention part 160 May contact the first plate D to which the second plate is not attached.

Meanwhile, while the roller 170 is in progress, the height of the first height adjusting part 120 and the second height adjusting part 130 may also vary. In detail, the first height variable part 121 in which the roller 170 moves toward the first height adjusting part 120 may be controlled to reduce the height. At this time, as the roller 170 progresses, the width between the second plate and the first plate D may be reduced, and the first height adjusting part 120 may support the first plate D. FIG.

While the height of the first height adjuster 120 is controlled, the height of the second height adjuster 130 may also be adjusted. Specifically, while the roller 170 proceeds as described above, the length of the second height variable portion 131 may be reduced, and the second bracket 133 may rotate about the second height variable portion 131.

In particular, while the roller 170 proceeds as described above, the curve of the first plate D in contact with the second buffer member 135 may vary. In this case, as described above, the elastic part may provide a restoring force to the second bracket 133 to correspond to the change of the first plate D curve.

On the other hand, the fall prevention unit 150 may also operate while the roller 170 is in progress as described above. In this case, the fall prevention unit 150 may operate in the opposite manner to that described in FIG. 6. Specifically, the fall prevention driving unit 151 may operate while the third height adjustment unit 140 descends.

The fall prevention driving unit 151 may move the fall prevention plate 152 from the first plate D side to the third height adjustment unit 140. At this time, the fall prevention plate 152 may be gradually reduced portion protruding from the third height adjustment unit 140. When the fall prevention plate 152 operates as described above, one end of the first plate D may be disposed to span the fall prevention plate 152 to prevent the fall.

Therefore, the plate bonding apparatus 100 may support the first plate D according to the height when the first plate D and the second plate are bonded to each other to prevent the first plate D from sagging or deforming. have. In addition, the plate bonding apparatus 100 adjusts the height of the first plate (D) according to the progress of the roller 170 to bond the first plate (D) and the second plate from one side to the other by the first plate It is possible to reduce the occurrence of bubbles between the second plate and the first plate (D) after the bonding of (D) and the second plate.

In particular, the plate bonding device 100 supports the first plate (D) according to the curvature of the first plate (D) during the bonding process, and prevents the fall of the first plate (D) to proceed the bonding quickly and when the bonding The failure rate that can occur can be minimized.
