Description

Sheet laminating device {SHEET LAMINATING MACHINE}

The present invention relates to a sheet laminating device for automatically attaching a laminated sheet to a base sheet of a certain standard.

In general, the pick-up and place method, which picks up the laminated sheet and attaches it to the base sheet as a method for automatically attaching the laminated sheet to the base sheet, is low in productivity in terms of process speed, especially for flexible sheets. In some cases, there is a problem that the precision is not high.

Meanwhile, as disclosed in Patent Registration No. 10-0796635 and Publication No. 10-2017-0135721, a roll to roll method in which base sheet and laminated sheet are each provided in the form of a roll and are continuously laminated to each other is used.

To this end, the sheet laminating device 100 according to an embodiment of the present invention starts from the loading part 101 through which the base sheet 1 is supplied, as shown in FIG. 2, and moves to the marking part 102 along the right transfer line. ), the top liner (2) or seal film (5) is attached to the laminated sheet attachment part (104) via the inspection part (103). Then, it is supplied to the opposite transfer line through the front (right) switching line, passes through the inspection section 105, is turned over in the inversion section 106, 107, and then is transferred to the double-sided adhesive sheet (3 or 4) at the laminated sheet attachment section 108. is attached. Afterwards, NG is determined at the NG inspection unit 109 on the front (left) changeover line, and then the finished product is discharged from the unloading unit 110.

The base material sheet 1 is transported in units of pallets 111. In other words, the relevant work is performed while the pallet 111 is transferred through each of the above-mentioned parts along the transfer line.

The laminated sheet attachment portion (typically 104, hereinafter the same) is provided by being wound in the form of a roll while reciprocating in the horizontal direction (up and down direction in Figure 2) with respect to the base sheet 1 on the pallet 111 transported to the corresponding location. A laminated sheet, typically a seal film (2), is removed from the carrier film and simultaneously attached to the base sheet (1).

In order to perform this task, the laminated sheet attachment portion 104 is a guide rail 121 extending in the horizontal direction (left and right directions in the drawing) along the transfer line (the direction through the ground in the drawing) as shown in FIG. 3. , It includes a carriage 122 that is mounted on the guide rail 121 and is slidably coupled to be driven back and forth (left and right in the drawing). The carriage 122 is driven back and forth by a feed motor 123 mounted on one end of the guide rail 121.

A supply roll 124 and a recovery roll 125 are installed at the upper end of the carriage 122. The carrier wound around the supply roll 124 by the recovery roll 125, which is rotated by the feed motor 126. The film 10 is wound on the recovery roll 125 through a certain recovery path. At this time, the laminated sheets 11 attached at regular intervals on the carrier film 10 are separated in the process of passing through the wedge 127 installed on the recovery path and placed on the pallet 111 by the lifting roller 128. It is attached to the base sheet (1).

The vacuum adsorption tensioner 130 installed on the recovery path adjacent to the wedge 127 adjusts the tension in the wedge 127 to meet requirements by vacuum adsorbing the carrier film 10.

Looking at the attachment process using the above configurations, when the carrier film 10 is transported along a certain recovery path by the rotational drive of the feed motor 126, the laminated sheet 11 being separated from the wedge 127 is detected. Driving of the feed motor 126 stops. This detection can be done by the sheet position sensor 129 installed at the upper end of the carriage 122 detecting the starting point 11a of the next laminated sheet 11.

Meanwhile, the pallet 111 includes a vacuum adsorption jig 112 on which the base sheet 1 is mounted on the upper surface and an elevating lift 113 that moves it up and down. As described above, one end of the laminated sheet 11 is a wedge ( 127) Under the separated condition, the lifting lift 113 is driven upward to raise the vacuum suction jig 112 as shown in FIG. 4.

Then, the lifting roller 128 drives downward to press the tip portion of the laminated sheet 11 separated from the carrier film 10 downward and attach it to one end of the base sheet 1.

In this state, the feed motor 123 at one end of the guide rail 121 rotates to move the carriage 122 backward, that is, to the right in the drawing, and at the same time, the recovery roll rotates due to the drive of the feed motor 126. The carrier film 10 is transported along the recovery path by (125). Accordingly, the laminated sheet 11 attached to the base sheet 1 due to the downward pressure of the lifting roller 128 begins to gradually attach to the base sheet 1, and by the time it reaches FIG. 5, the base sheet 1 has been completely removed. is attached to

Afterwards, the lifting roller 128 is driven upward as shown in FIG. 6, and the lifting lift 113 of the pallet 111 is driven downward to lower the vacuum suction jig 112. Then, the feed motor 126 and the recovery roll 125 are driven to rotate until the next laminated sheet 11 is positioned on the wedge 127 and then stop. Then, the carriage 122 moves forward and returns to the left due to the rotational drive of the feed motor 123, so that the conditions of FIG. 3 are met. Of course, the pallet 111 is replaced with a new neighboring pallet, that is, a new pallet on which the base material sheet 1 is mounted.

Meanwhile, referring to FIG. 3, in order to adjust the position error and angle error between the base sheet 1 and the laminated sheet 11 attached thereto, the laminated sheet attachment portion 104 is a rotary device that supports the guide rail 121. It includes a stage 131 and an X-Y stage 132 that supports and supports the rotary stage 131. By the rotary stage 131, the guide rail 121 is rotated to adjust the alignment angle with respect to the vacuum suction jig 112, and by the X-Y stage 132, the vacuum suction jig 112 of the guide rail 121 ) is driven horizontally and vertically to adjust the horizontal position error.

Meanwhile, the vacuum suction jig 112 of the pallet 111 has a suction plate 141 on which the base sheet 1 is vacuum suctioned to the upper surface, as shown in FIGS. 7 and 8, and is disposed at the lower part of the suction plate 141. It is provided with a support plate 142 to support it. The bottom of the support plate 142 is coupled to the top of the lifting lift 113.

The suction plate 141 has a plurality of vacuum suction ports 143 distributed in a rectangular shape on the inside of the upper surface to realize or release vacuum suction on the upper surface through the suction air inlet 144 and outlet 145 on the side. make it possible

A guide dog (146) is installed so as to protrude on the outside of each of the four corners of the plurality of rectangular vacuum suction ports (143) on the upper surface of the suction plate (141), thereby preventing the attached base sheet (1) from being separated. It is used as a means.

Meanwhile, the suction plate 141 is not directly supported by the upper surface of the support plate 142, but is inserted and installed between the upper receiving groove 141a on the bottom of the suction plate 141 and the lower receiving groove 142a on the upper surface of the support plate 142. It is supported via a plurality of springs 147. Accordingly, the precision of the support plate 142 supporting the suction plate 141 can be improved. That is, in the process from Figure 4 to Figure 5, the pressing force caused by the lifting roller 128 is prevented from being unevenly distributed depending on the position, and the laminating quality is improved by ensuring that the sheets 1 and 11 are always attached at a constant pressure. You can.

Referring to FIGS. 7 and 8, a plurality of tapered grooves 142b are distributed and formed on the bottom of the support plate 142, and correspondingly, the elevating lift 113 has a pedestal 148 at the top supporting the support plate 142. A tapered pin 151 is protrudingly formed on the upper surface of . Through this coupling/separation structure of the tapered groove 142b and the tapered pin 151, the precision of the coupling position of the support plate 142 with respect to the lifting lift 113 can be further increased.

Furthermore, as shown in FIG. 9, a plurality of balls 152 are installed on the outer peripheral surface 151a forming the tapered surface of the tapered pin 151 through the cage 153, and through these balls 152 By forming point contact coupling with the tapered groove 142b on the support plate 142 side, it is possible to secure very excellent coupling position precision.

At this time, the tapered groove 142b on the support plate 142 side is formed on the inner circumferential surface of the bearing housing 154 inserted into the bottom surface of the support plate 142 to enable the combination of the bearing housing 154 and the tapered pin 151. It is desirable to prepare it through a separate precision process.

Meanwhile, since the sheet laminating device 100 described above is only an example to aid understanding of the present invention, the scope of rights or technical scope of the present invention defined by the claims described later is not limited to what is described above. no.
