Abstract

PURPOSE:To form exactly and quickly a thin material as one body without causing a mutual position shift, by positioning the thin material by plural holding claws projecting onto a placing surface, and also, moving the holding claw in the lower direction by a pressure means. CONSTITUTION:After a thin material M has been placed on a placing surface 2, when pressure of a piston 9 is released, the piston 9 is slid downward by elasticity of a spring 10. As a result, each holding claw 6 is made to approach each other by elastic pressure of a spring member 8, plural superposed thin materials are welded by pressure in the horizontal direction from the outside and external forms of th thin materials are aligned, and each tip member 6b holds the thin material M by a prescribed force. In this way, the thin materials M are positioned exactly on the placing surface 2, in a state that the external forms have been matched to each other. Subsequently, when they are pressed from the upper part by a pressure means, and also, heated, the holding claw 6 is slid downward, and also, the thin materials M are welded by pressure thermally to each other in state that they have been positioned by pressure force and heating.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a positioning jig capable of positioning a plurality of superimposed thin materials having the same external shape and bonding them together by thermocompression.

[Prior art and problems to be solved by the invention] Normally, when thin materials having the same external shape used for electronic components, etc. are to be integrated with each other, the individual thin materials are once overlapped at a predetermined position. , and then these are integrated by thermocompression bonding or the like. Since this type of thin material requires extremely high dimensional accuracy, the outer shapes of each thin material must be matched when they are integrated. It is an object of the present invention to provide a positioning jig that can be accurately and quickly integrated without causing problems.

[Means and effects for solving the problem] In the positioning jig according to the present invention, a plurality of thin materials superimposed on a predetermined f2 mounting surface are positioned by a plurality of gripping claws protruding on the 1iT1 surface. At the same time, the gripping claws are moved below the placing surface by a suppressing means capable of pressing the thin material from above the stone surface. Therefore,
Thermocompression bonding can be performed while the outer shapes of the thin materials are exactly matched to each other, and as a result, the consistency of the outer shapes can be improved and high precision can be ensured.

〔Example〕

1 and 2 show an embodiment of the positioning jig according to the present invention, and in the figures, 1 is an object on which the thin materials M to be overlapped can be placed! 3! A base plate block 3, which is perpendicular to the mounting surface, has a plurality of through holes which are opened in the mounting surface, and which are arranged at slight intervals from the thin material M, and is fixed to the pedestal 1'. 5 is a holder that is movably suspended from the bottom of the base plate block 1 in a direction perpendicular to the base plate block 1 via a guide pin 4, and 5 is a guide pin 4 fixed to the holder 3 side.
A coil spring 6 is a resilient member that presses the holder 3 against the block 1 by pressing upward, and when the holder 3 is in the normal state in which the holder 3 is pressed, its tip 6a is ! ! The thin material M is pivotally attached to the holder 3 via the pivot shaft 7 so as to protrude from each through hole on the mounting surface 2, and when the holder 3 is lowered, the vertical portion formed inside the opposing tip portion 6a becomes the thin material M. A plurality of gripping claws 8 are adapted to be lowered while contacting the outer edges of the gripping claws, and a guide surface 6b is formed at the base thereof and is inclined about 1° with respect to the vertical direction. A ring-shaped elastic member 9 made of a coil spring that presses the tips 6a of the gripping claws 6 toward each other is slidably mounted on the holder 3 and resists the elastic force of the spring 10. By sliding the head 9a upward while being in pressure contact with the guide surface 6b of each gripping claw 6, the gripping claws 6 can be pushed away from each other all at once against the elastic force of the elastic member 8. It's a piston. Note that the gripping claws 6a are as shown in the figure.
A pair of opposing gripping surfaces are formed as flat surfaces, and the other pair of opposing gripping surfaces are formed as arcuate surfaces, so that when the gripping claws 6a grip a plurality of thin materials M, A pair of opposing sides of M are held in a surface contact state, and another pair of opposing sides are held in a line contact state to form a plurality of thin materials M.
is designed to maintain extremely high polymerization accuracy whenever it is gripped.

Since the positioning jig according to the present invention is constructed as described above, first, in the normal state where the holder 3 is pressed against the base plate block 1, when the piston 9 is slid upward, the head 9a is moved to the gripping claw 6. As a result, each gripping claw 6 is made to swing around the pivot shaft 7 against the elastic force of the elastic member 7, and the tip members 6a are separated from each other all at once. A region is defined on the placement surface 2 in which the thin material M to be integrated between the respective tip members 6a can be placed. When the thin material M is placed on the placement surface 2 and the pressure of the rear piston 9 is released,
The piston 9 is slid downward by the elasticity of the spring IO, and as a result, each gripping claw 6 is brought close to each other by the elastic force of the elastic member 8, and is horizontally moved from the outside against the stacked thin materials. Each tip member 6b grips the thin material M with a predetermined force and stops the thin material M by pressing in the direction to match the outer shape of the thin material M. In this way, the thin materials M are precisely positioned on the mounting surface 2 with their external shapes matched to each other. In this state, when the thin material M is pressed from above by a pressing means (not shown) and heated at an appropriate temperature, the gripping claws 6 are pushed together with the holder 3 downward against the elastic force of the spring 5 due to the pressing force. While being moved, the thin materials M are thermocompressed to each other while being positioned by the applied pressure and heating. Thereafter, when the pressure by the pressing means is released, the holder 3 is returned to its normal state by the elastic force of the spring 5, and one operation is completed.

In the above embodiment, each operation such as pressing the piston 9, supplying the thin material M onto the placement surface 2, or pressing the thin material M by the pressing means may be performed manually or automatically, and may be operated as appropriate. form can be taken. When opening and closing the gripping claw 6, a guide surface 6b' is formed below and outwardly from the pivot shaft 7 of the gripping claw 6 and is inclined downwardly and inwardly, and a guide surface 6b' is movable up and down outside the guide surface 6b'. It is also possible to open and close the gripping claws 6 by disposing an annular member and moving the member up and down while pressing the inner wall of the member against the guide surface 6b'. Moreover, the gripping claws 6 for positioning the thin material M according to its outer shape may be added as appropriate. Furthermore, the thin material M to be integrated may be composed of two or more pieces, and although the positioning jig of the present invention is particularly effective for thin materials, it is not limited to thin materials but can also be used for plate-like materials. The present invention can be similarly effectively applied to all polygons, and as long as the outer shape is the same in all cases, it can be applied to all three circular or annular polygons, and the same effects as in the above embodiment can be obtained.

〔Effect of the invention〕

As described above, the positioning jig of the present invention is particularly applicable to thermocompression bonding of thin materials, and can accurately and smoothly integrate the thin materials by twisting, and can also improve the processing efficiency of such thin materials. This has advantages such as the ability to achieve
