[Detailed description of the device]

 Purpose of devising

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adhering two sheet-like objects in a precise positional relationship. This device is particularly useful when used for laminating with an adhesive.

[Prior art]

For example, when manufacturing a keyboard switch with a large number of contacts, conventionally, a spacer made of silk screen printing such as silicone resin was provided on either of the upper and lower contact support plates, and the main parts in the periphery or in the middle were provided. A technique is used in which a double-sided adhesive tape is placed and two sheets are pressed and bonded together. This work is labor-intensive, and in order to attach the two sheets in a correct positional relationship, great care must be taken and productivity is low. The present inventor has proposed punching a double-sided adhesive sheet into a spacer shape in response to a demand for ensuring adhesion between contact support plates over the entire surface of a keyboard switch, but the work is also conventional. When the method is used, the pressure-sensitive adhesive sheet is twisted, which makes it difficult to carry out.

[Problems to be solved by the device]

An object of the present invention is to solve the above-mentioned problems and to provide a device that facilitates bonding in an accurate positional relationship when two sheet-like materials are integrated by using an adhesive. . Device configuration

[Means for solving problems]

As shown in the drawings, the sheet-shaped material laminating apparatus of the present invention comprises a stage 1 and a frame 2 on which a screen 3 is stretched, which is separated from the stage 1 and can return to a certain position. The stage 1 is provided with a means 11 for determining the position of the sheet to be bonded, and the back surface of the screen 3 is made to have a weak adhesive property.

[Action]

To bond two sheets using this device,
First, as shown in FIGS. 1 and 2, the frame 2 is separated from the stage 1, and the first sheet 6 is placed at a predetermined position on the stage 1 by using the position determining means 11. Put the frame 2 back on the stage 1 and from the top of the screen 3
For example, as shown in FIG. 3, when the whole is pressed by means such as a rubber roller 9, the first sheet 6 is lifted up even if the first sheet 6 adheres to the back surface of the screen 3. Then, the second sheet 7 is placed at a predetermined position on the stage, and an adhesive is applied or a double-sided adhesive sheet 8 is attached thereon. When the frame 2 is moved and the screen 3 is moved down, the first sheet 6 returns to its original position, so that the second sheet 7 and the double-sided adhesive sheet 8 are sandwiched at a certain position. If the roller is brushed again, the two sheets are integrated and the product as shown in FIG. 4 is obtained. Since the screen 3 and the first sheet 6 have a weak adhesive property, they can be easily separated.

【Example】

If the stage 1 and the frame 2 are coupled to each other by using a hinge 4 as shown in the example of the drawing, the structure of the device is simple and convenient. Of course, other structures, such as a mechanism in which the frame moves up and down in parallel along a guide set up on the stage, can be adopted. A combination of pin 21 and pin hole 12 as shown may be used if necessary to ensure that the frame always returns to a consistent position, or vacuum may be considered in automated equipment. To be The screen 3 may be convenient to operate if it comprises a transparent film or mesh, for example a silk screen printing mesh. To impart weak tackiness, a commercially available weak tacky film may be used or a weak tackiness agent may be sprayed. Effect of the Invention By using the device of the present invention, pasting of sheet-like materials using an adhesive, which has been difficult in the past, can be performed in an accurate positional relationship without paying special attention. it can. Therefore, as productivity increases,
Good product yield can be obtained.
