The first vacuum press bonding device of the above type.
What is shown in FIGS. 2 and 2 has been proposed by the present inventor. In each figure, reference numeral 1 designates a base body that incorporates a vacuum pump 2 and performs evacuation through an intake hole 3 provided on the upper surface side. goes up and down. The bell gear 5 consists of a box with an opening at the bottom, and an elastic sheet 6 made of rubber or the like is fixed to the opening 5a so as to close the opening 5a.

Blocks 11, 11, which are taller than the holding frame 8 and the adhered member 7 placed on the holding frame 8, are fixed on both sides of the holding frame 8 so as to be parallel to the holding frame 8. . Note that 22 is a heater provided in the bell gear 5, which softens the adhesive tape 9 and improves its adhesive strength.

To adhere the adhesive tape 9 to the adhered member 7,
First, as shown in FIG. 3, the back side of the tape 9 is temporarily attached to the adhered member 7 by hand, and then, as shown in FIG. Then, the elevator 4 is activated to lower the bellgear 5 and vacuum is applied, thereby sucking the elastic sheet 6 in the direction of the substrate 1, so that the sheet 6 is attracted to the entire surface of the member 7 to be adhered. Since strong pressure is applied to the tape 9, the tape 9 can be bonded.

In this case, as shown in FIG. 2, the elastic sheet 6 is suctioned downward while bridging the blocks 11 and 11, so that the bridging portion is suctioned so as to hang down in a U-shape. After the lowermost position 6a of the adhesive tape 9 comes into line contact with the adhesive tape 9, the adhesive tape 9 is attracted so as to spread laterally from the lowermost position 6a. By applying pressure to the adhesive tape so that the elastic sheet 6 gradually spreads outward from one point, air bubbles interposed between the adhesive tape 9 and the member to be bonded 7 are expelled, so that air bubbles between the two are expelled. No longer visible to the naked eye, aesthetic appearance,
It can enhance decorativeness and maintain adhesive strength for a long time.

However, with such a configuration, an unnecessary triangular space A is always generated between the outside of the block 11 and the elastic sheet 6, and this space A must be evacuated with the vacuum pump 2. This has the disadvantage that the bonding process cannot be completed in a short time and mass productivity is reduced.

An object of the present invention is to eliminate the above drawbacks by reducing the volume of the space to be evacuated, and will be described in detail below using Examples.

FIG. 4 is a simplified configuration diagram showing an embodiment of the vacuum press bonding apparatus according to the present invention, and the same parts as in FIG. 1 are designated by the same reference numerals. In the figure, 12 is a spacer located in an unnecessary space A created on the side of the block 11.
It has almost the same shape as the triangular space A surrounded by the base body 1 and the base body 1, and is made of wood, synthetic resin, etc., for example. Reference numeral 10 denotes an airtight, non-stretchable sheet such as canvas located above the elastic sheet 6, and is fixed to the open end side of the bell gear 5 together with the elastic sheet 6. Air from a pressure pump 13 is supplied between the elastic sheet 6 and the sheet 10 via a conduit 14.

In the above configuration, after lowering the bell gear 5 to the top of the base 1, the vacuum pump 2 and the pressure pump 13 are operated to suck air from the intake hole 3, and air is supplied from the conduit 14. After the elastic sheet 6 bends into a U-shape, pressure is applied to the film 9. According to this embodiment, since the space for vacuuming is only between the blocks 11 and 11, this vacuuming work can be done in a short time. We decided to supply
The elastic sheet 6 can be bent more efficiently. Incidentally, since the space in which the air is supplied is a small space between the elastic sheet 6 and the sheet 10, the amount and time of supply of this air can be shortened. In addition, when vacuuming is performed while leaving unnecessary space A as in the past, the elastic sheet 6 is stretched excessively in this unnecessary space A, so the elastic sheet 6 is easily fatigued in this area and damaged in a short period of time. However, by arranging the spacer 12 in this unnecessary space A, excessive stretching of the elastic sheet 6 is forcibly prevented, so fatigue does not occur in this part and the elastic sheet 6 is kept stable for a long time. and can be used.

As explained above, according to the present invention, the elastic sheet placed on the top of the evacuated base is sucked toward the base, and the surface side of the member to be adhered held on the base is covered with the elastic sheet. In the vacuum press bonding machine that applies bonding pressure, spacers are installed on the side of the bonded parts to reduce the vacuum space, which reduces the vacuuming work time, improves mass productivity, and reduces the burden on the vacuum pump. can be reduced.
