The panel seating plate rotating device 126 is fixed to the four branch ends of the turntable 111, and the panel seating plate 112 is coupled to the panel seating plate rotating device 126. The panel seating plate 112 may rotate in a state where the panel seating surface 113 is parallel to the ground by the panel seating plate rotating device 126.

The panel seating plate 112 has a flat panel seating surface 113 on which the panel assembly 10 is placed. A plurality of suction holes 114 are formed in the panel seating surface 113. The plurality of suction holes 114 are connected to the air flow path 115 provided inside the panel seating plate 112. The air flow path 115 is connected to the vacuum tube 120 to transmit the vacuum pressure through the vacuum tube 120.

Can be.

As shown in FIG. 3, the panel seating plate rotating device 126 is coupled to the rotary table 111 to rotate the panel seating plate 112 at 90 degree intervals. Since the panel seating plate 112 is rotated, when the vacuum tube 120 is directly coupled to the panel seating plate 112, the vacuum tube 120 may be twisted. The rotary joint 127 is coupled to the panel seating plate 112 to prevent the vacuum tube 120 from being twisted. The rotary joint 127 includes a fixing part 129 coupled to the panel seating plate 112 and having a rotary part 128 that rotates together with the panel seating plate 112 and a vacuum tube 120.

In the rotary part 128 and the fixing part 129 of the rotary joint 127, connection flow paths (not shown) are always provided even though they rotate relative to each other. Therefore, even if the panel seating plate 112 rotates, the vacuum tube 120 does not move on the rotary table 111 but is connected to the panel seating plate 112 through the connection flow path between the fixing part 129 and the rotating part 128. Vacuum pressure can be provided.

 The fixing part 129 of the rotary joint 127 is coupled to the panel seating plate rotating device 126. The power transmission member of the panel seating plate rotating device 126 such as a rotating shaft for transmitting rotational force to the panel seating plate 112 may be coupled to the panel seating plate 112 through the rotary joint 127.

When the panel mounting plate 112 moves from the first ultraviolet irradiation zone Z2 to the second ultraviolet irradiation zone Z3, the panel mounting plate rotating device 126 operates to rotate the panel mounting plate 112 by 90 degrees.

Whether the panel mounting plate 112 is rotated in the remaining position may be variously set. That is, the panel seating plate rotating device 126 may be used when the panel seating plate 112 moves from the loading zone Z1 to the first ultraviolet irradiation zone Z2, or the unloading zone Z4 in the second ultraviolet irradiation zone Z3. ), Or when moving from the unloading zone Z4 to the loading zone Z1, the panel seating plate 112 may or may not be rotated. The operation of the panel mounting plate rotating device 126 is the structure of the loading device 170 or the unloading device 175, the structure of the first ultraviolet irradiation device 130 and the second ultraviolet irradiation device 160 or the ultraviolet irradiation operation The structure of the panel seating plate 112 may vary.

As shown in FIGS. 1, 5 and 6, the first ultraviolet irradiation device 130 and the second ultraviolet irradiation device 160 irradiate ultraviolet rays to the panel assembly 10 placed on the panel seating table 110. In order to harden the ultraviolet curing agent 13 of the panel assembly 10, it is arrange | positioned in the 1st ultraviolet irradiation zone Z2 and the 2nd ultraviolet irradiation zone Z3, respectively. The first ultraviolet irradiation device 130 and the second ultraviolet irradiation device 160 differ only in the installation position, but the specific structure is the same. Hereinafter, a detailed structure of the first ultraviolet irradiation device 130 will be described, and a description of the specific structure of the second ultraviolet irradiation device 160 will be omitted.

As shown in FIGS. 5, 7 and 8, the first ultraviolet irradiation device 130 includes a pair of lamp assemblies 131, a lamp assembly support 136 for supporting a pair of lamp assemblies 131, And a pair of lamp assembly movers 137 for moving each lamp assembly 131.

The ultraviolet lamp 132 is disposed horizontally with the panel assembly 10 at the same height as the panel assembly 10 to irradiate ultraviolet rays to the outer edge of the panel assembly 10 placed on the panel seating table 110. In addition, the auxiliary ultraviolet lamp 133 is disposed to be inclined toward the edge of the panel assembly 10 at a position higher than the panel assembly 10 to irradiate ultraviolet rays obliquely from one surface of the panel assembly 10 toward the outer edge.

Ultraviolet rays irradiated from the ultraviolet lamp 132 to the outer edge of the panel assembly 10 may penetrate to the inside of the panel assembly 10 and may not sufficiently cure the ultraviolet curing agent 13 inside the panel assembly 10. Therefore, when ultraviolet rays are irradiated from the inside to the outer edge through one surface of the panel assembly 10 through the auxiliary ultraviolet lamp 133, the ultraviolet curing agent 13 inside the panel assembly 10 that is not cured by the ultraviolet lamp 132 is removed. It can harden enough.

The lamp support 134 is provided with a joint 135 for supporting the auxiliary ultraviolet lamp 133 so that the angle can be adjusted. Therefore, the angle of the auxiliary ultraviolet lamp 133 can be adjusted, and the operator adjusts the placement angle of the auxiliary ultraviolet lamp 133 to adjust the irradiation angle of ultraviolet rays irradiated from the auxiliary ultraviolet lamp 133 to the panel assembly 10. I can regulate it.

The lamp assembly 131 may be moved by the lamp assembly moving device 137 in a direction closer to the panel assembly 10 or in a direction away from the panel assembly 10. The lamp assembly moving device 137 is coupled to the fixing part 139 provided on the lamp assembly support 136. The lamp assembly moving device 137 has an operating member 138 for pushing or pulling the lamp assembly 131, and the operating member 138 is coupled to the engaging portion 140 provided on the lamp support 134. The coupling part 140 of the lamp support 134 may be stably linearly moved by being supported by the plurality of guide bars 141 to be fixed to the fixing part 139 of the lamp assembly support 136.

The lamp assembly 131 may move linearly by pushing or pulling the lamp support 134. The separation distance of the ultraviolet lamp 132 from the panel assembly 10 and the auxiliary ultraviolet lamp 133 from the panel assembly 10 are changed by the action of the lamp assembly moving device 137. Also, the distance between the pair of lamp assemblies 131 may be varied by the action of the lamp assembly moving device 137. Therefore, when the lamp assembly 131 is moved using the lamp assembly moving device 137 according to the size of the panel assembly 10 or the output intensity of the ultraviolet lamp 132 or the auxiliary ultraviolet lamp 133, panels of various sizes can be obtained. Ultraviolet rays can be irradiated to the binder 10 efficiently. As the lamp assembly moving device 137, various devices capable of linearly moving the lamp assembly 131 such as a pneumatic cylinder, a hydraulic cylinder, a linear motor, and a ball screw device may be used.

The first ultraviolet irradiation device 130 may be moved by the first ultraviolet irradiation device moving unit 150. The first ultraviolet irradiation device moving unit 150 moves the lifting device 151 and the first ultraviolet irradiation device 130 to move the first ultraviolet irradiation device 130 in the vertical direction to the outer edge of the panel assembly 10.

The lamp assembly support 136 may be stably linearly moved by being supported by the moving support 153 by the plurality of guide bars 154.

When the elevator 151 pushes or pulls the lamp assembly support 136, the height of the first ultraviolet irradiation device 130 is changed to change the height of ultraviolet irradiation of the ultraviolet lamp 132 and the auxiliary ultraviolet lamp 133. As the elevating device 151, various devices capable of linearly moving the lamp assembly support 136 such as a pneumatic cylinder, a hydraulic cylinder, a linear motor, and a ball screw device may be used.

The retraction device 155 includes an operation member 156 that pushes or pulls the movable support 153 to which the elevating device 151 is coupled, and is installed on the fixed support 157 coupled to the support pillar 158. The operation member 156 of the retraction device 155 is coupled to the moving support 153. The moving support 153 is movably supported by the fixed support 157 by the plurality of guide bars 159 to stably linearly move.

When the retractor 155 pushes or pulls the movable support 153, the first ultraviolet irradiator 130 moves linearly along the outer edge of the panel assembly 10, and the ultraviolet lamp 132 and the auxiliary ultraviolet lamp 133 are moved. The ultraviolet irradiation point of) moves along the outer edge of the panel assembly 10. Accordingly, when the first ultraviolet irradiation device 130 is moved by the advancing device 155 by the outer edge length of the panel assembly 10, the ultraviolet lamp 132 in the form of one point light source and the auxiliary ultraviolet lamp in the form of one point light source.

As the retraction device 155, various devices capable of linearly moving the moving support 153 such as a pneumatic cylinder, a hydraulic cylinder, a linear motor, and a ball screw device may be used.

The second ultraviolet irradiation device 160 differs only in the installation position, and the specific structure thereof is the same as that of the first ultraviolet irradiation device 130. The second ultraviolet irradiation device 160 is moved by the second ultraviolet irradiation device moving unit 165. The specific structure of the second ultraviolet irradiation device moving unit 165 is the same as the first ultraviolet irradiation device moving unit 150.

In the present invention, the structure of the ultraviolet irradiation device 130, 160 or the ultraviolet irradiation device moving unit 150, 165 may be variously changed. For example, the ultraviolet irradiation device 130, 160 may include one or three or more lamp assemblies 131. Since most panel products have a square shape, when two or more lamp assemblies 131 are provided, the lamp assemblies 131 may be arranged to face each other in an even number. As illustrated, when two lamp assemblies 131 are provided, ultraviolet rays may be irradiated to both outer edges of the panel assembly 10 simultaneously, and when the four lamp assemblies 131 are disposed to face each other, the panel assembly 10 may be disposed. Ultraviolet rays can be irradiated to the four outer edges of the panel simultaneously, reducing work time.

When the ultraviolet irradiation device 130 or 160 has one lamp assembly 131, the panel mounting plate rotating device 126 is used to move to the first ultraviolet irradiation zone Z2 or the second ultraviolet irradiation zone Z3. Ultraviolet rays can be irradiated to the outer edge of the panel assembly 10 while rotating one panel assembly 10. When the panel assembly 10 is rotated in the first ultraviolet irradiation zone Z2 or the second ultraviolet irradiation zone Z3, one or more lamp assemblies 131 move linearly to expose the ultraviolet light to at least two sides of the panel assembly 10. Can be investigated.

It can be changed to form a surface light source. When the ultraviolet lamp 132 or the auxiliary ultraviolet lamp 133 is changed into the shape of the line light source or the surface light source of the appropriate size, it is possible to cure the ultraviolet curing agent of the panel assembly 10 without moving them. The structure of 150) 165 can be simplified.

The lamp assembly moving device 137 may be changed to a structure that rotates the lamp assembly 131 along the outer circumference of the panel assembly 10. The ultraviolet irradiation device moving unit 150 and 165 may have a structure that rotates along the outer circumference of the panel assembly 10 in addition to the operation of raising or lowering the ultraviolet irradiation device 130 or 160.

In addition, the number or arrangement of the ultraviolet irradiation device 130, 160 and the ultraviolet irradiation device moving unit 150, 165 for moving it may be variously changed according to the structure of the panel seating table 110. That is, when the number of panel seating plates 112 is increased on the panel seating table 110, the number of installation of the ultraviolet irradiation device 130, 160 and the ultraviolet irradiation device moving unit 150, 165 may also increase. The spacing can also be changed at an angle smaller than 90 degrees. The number or arrangement of the loading device 170 or the unloading device 175 may also change depending on the number of installation of the panel seating plate 112.

The turntable rotating device 117, the vacuum pressure providing device 124, the plurality of panel seating plate rotating devices 126, the first ultraviolet irradiation device 130, the second ultraviolet irradiation device 160, and the first ultraviolet irradiation The operation of the device moving unit 150, the second ultraviolet irradiation device moving unit 165, the loading device 170, and the unloading device 175 are collectively controlled by the controller 180.

That is, when the panel seating plate 112 moves to the loading zone Z1, the loading device 170 should load the panel assembly 10 quickly, and the panel assembly 10 loaded on the panel seating plate 112 is When moved to the first ultraviolet irradiation zone Z2 or the second ultraviolet irradiation zone Z3, the first ultraviolet irradiation device 130 and the first ultraviolet irradiation device moving unit 150 or the second ultraviolet irradiation device 160 and the 2 UV irradiation device mobile unit 165 is to operate quickly to irradiate the ultraviolet rays to the outer edge of the panel assembly (10). In addition, when the panel assembly 10 subjected to UV irradiation moves to the unloading zone Z4, the unloading device 175 should unload the panel assembly 10 from the panel seating plate 112. In addition, the table rotating apparatus 117, the panel mounting table 110 when the work in the loading zone (Z1), the first ultraviolet irradiation zone (Z2), the second ultraviolet irradiation zone (Z3) and the unloading zone (Z4) is completed. ), The panel seating plate 112 must be moved quickly to the next working zone by rotating the lens at an angle. Such loading, ultraviolet irradiation, and unloading operations are controlled organically by the controller 180.

When the panel assembly 10 moves to the second ultraviolet irradiation zone Z3, the second ultraviolet irradiation device 160 and the second ultraviolet irradiation device moving unit 165 operate to operate on the remaining two sides of the panel assembly 10. Ultraviolet rays are irradiated to cure the remainder of the outer edge of the panel assembly 10.

When the ultraviolet irradiation is finished in the second ultraviolet irradiation zone Z3, the table rotating device 117 rotates the panel seating table 110 by 90 degrees to move the UV-irradiated panel assembly 10 to the unloading zone Z4. Let's do it. When the panel assembly 10 moves to the unloading zone Z4, the unloading device 175 operates to unload the UV cured panel assembly 10 from the panel seating table 110. When the panel assembly 10 is unloaded from the panel seating plate 112, the table rotating device 117 rotates the panel seating table 110 by 90 degrees to move the panel seating plate 112 to the loading zone Z1. .

As described above, the panel bonding apparatus 100 according to the present invention includes a loading device 170 and a first ultraviolet ray installed in a rotation path of the panel seating table 110 while rotating the panel seating table 110 on which the panel assembly 10 is placed. By using the irradiation device 130, the second ultraviolet irradiation device 160, the unloading device 175 in order to perform the loading operation, ultraviolet irradiation operation, unloading operation in order, the panel assembly 10 continuously and quickly It can bond efficiently. Particularly, the ultraviolet irradiation work for one panel assembly 10 is continuously performed by the plurality of ultraviolet irradiation devices 130 and 160, and the panel assembly 10 is formed in the plurality of ultraviolet irradiation zones Z2 and Z3. UV irradiation work for) can be performed at the same time, it is possible to shorten the bonding time of the panel assembly 10. In addition, since the UV lamp 132 and the auxiliary UV lamp 133 which are provided in the UV irradiation device 130 and 160 can move and the UV irradiation height can be adjusted, panel combinations of various sizes and various thicknesses are provided. Adhesion operation to 10 is possible.

On the other hand, Figure 9 and Figure 10 shows a panel bonding apparatus according to another embodiment of the present invention, respectively. The panel bonding apparatus according to another embodiment of the present invention is the same as the panel bonding apparatus 100 according to the embodiment of the present invention, most of the configuration. Hereinafter, the same reference numerals are given to the same parts as the above-described configuration, and detailed description thereof will be omitted.

The panel bonding apparatus 200 shown in FIG. 9 is somewhat different in the structure of the panel seating table 210 compared to the panel bonding apparatus 100 according to the embodiment of the present invention described above. The arrangement direction of the irradiation device 160 is different.

The panel bonding apparatus 200 according to another embodiment of the present invention has two panels of the panel assembly 10 in which the first ultraviolet irradiation device 130 is placed on the panel seating plate 212 in the first ultraviolet irradiation zone Z2. Ultraviolet rays are irradiated to the sides to ultraviolet-cure the portion of the outer edge of the panel assembly 10, and in the second ultraviolet irradiation zone Z3, the second ultraviolet irradiation device 160 emits ultraviolet rays to the other two sides of the panel assembly 10. Is irradiated to cure the remaining outer edges of the panel assembly 10.

Since the panel assembly 10 positioned in the first ultraviolet irradiation zone Z2 moves to the second ultraviolet irradiation zone Z3 by rotating the panel seating table 210 by 90 degrees, the panel assembly 10 moves in the first ultraviolet irradiation zone Z2. The panel assembly 10 and the panel assembly 10 in the second ultraviolet irradiation zone Z3 have a phase difference of 90 degrees. Therefore, even when the first ultraviolet irradiation device 130 and the second ultraviolet irradiation device 160 irradiate ultraviolet rays to the panel assembly 10 while moving in the same direction, each of the ultraviolet irradiation devices 130 and 160 is a panel assembly ( Ultraviolet rays are irradiated to different sides of 10), and as a result, the entire outer edge of the panel assembly 10 is irradiated with ultraviolet rays by the two ultraviolet irradiation devices 130 and 160.

Since the panel bonding apparatus 200 according to another embodiment of the present invention does not need to rotate the panel seating plate 212, there is an advantage that the structure of the panel seating table 210 can be simplified. In some cases, the panel seating plate 212 may be omitted. That is, a flat panel seating surface on which the panel assembly 10 can be placed is provided on the upper surface of the rotating table 211, and a vacuum pressure tube 120 for providing suction force to the adsorption hole of the panel seating surface is provided on the rotating table 211. ) May be directly connected.

It has a structure which can advance and retreat by (155).

The first ultraviolet irradiation device 130 and the second ultraviolet irradiation device 160 are connected to the connection member 310. The connecting member 310 connects the moving support 153 connected to the first ultraviolet irradiation device 130 and the moving support 153 connected to the second ultraviolet irradiation device 160, and the retreating device 310 is connected to the connecting member 310. The operating member 156 of the 155 is coupled. The connection member 310 is supported by the plurality of guide bars 159 so as to be movable to the fixed support 157 to which the retraction device 155 is fixed. When the advancing and retreating device 155 pushes or pulls the connecting member 310, the first ultraviolet light irradiation device 130 and the second ultraviolet light irradiation device 160 connected thereto are simultaneously moved.

The panel bonding apparatus 300 according to another embodiment of the present invention can simultaneously move two ultraviolet irradiation devices 130, 160 with one advancing device 155, reducing the number of components The unit price can be lowered. In addition, the overall structure can be simplified.

In addition, the structure of the panel bonding apparatus according to the present invention can be variously changed. For example, the panel seating table 210 may be disposed such that the panel seating surface 113 on which the panel assembly 10 is seated does not face upward, but face downward, as shown. When the suction force is provided to the panel seating surface 113 by the suction force providing means, even when the panel seating surface 113 faces downward, the panel assembly 10 may remain attached to the panel seating surface 113 during ultraviolet irradiation. .
