Hereinafter, embodiments of the present invention will be described. In addition, the same or equivalent portions are denoted by the same reference numerals, and the description thereof may not be repeated.

In addition, in the embodiments described below, the scope of the present invention is not necessarily limited to the number, the amount, and the like, except the case where there is a substrate in particular. In the following embodiments, each component is not necessarily essential to the present invention except for the case where there is a substrate in particular.

1 is a plan view showing an overall configuration of a compression molding apparatus according to the present embodiment. As shown in Fig. 1, the compression molding apparatus according to the present embodiment includes a mold mechanism unit 1000 for compressing (resin sealing) a substrate (insert member) on which a semiconductor chip is mounted, An inhaler unit B including an inserter 20 for supplying an insert member to a molding die of the molding unit A and an inserter And an out-loader unit (C) including an out-loader (30) for taking out the molded article and a containing portion for receiving the molded article. The in-loader 20 and the out-loader 30 move in the vertical direction in Fig. Each of the molding units A is provided with an adjusting mechanism 100 to be described later in order to adjust the degree of parallelism of the mold surface of the molding die.

The molding unit A, the in-loader unit B and the out-loader unit C are detachably connected to each other through a connecting mechanism such as a bolt or a pin. In the example of Fig. 1, two molding units A are provided, but this number can be adjusted in accordance with the production amount. The number of the molding units A may be one or four, for example, as shown in Fig.

1 and 2, the molding unit A, the in-loader unit B and the out-loader unit C are provided in this order. However, for example, the molding unit A, One master machine in which the unit B and the out-loader unit C are integrated and one or a plurality of slave machines having only the molding unit A are arranged to constitute a compression molding apparatus .

In addition, in the examples shown in Figs. 1 and 2, the insert member and the resin material may be manually supplied to the molding unit A, and the molded article after molding may be taken out.

Next, the structure of the mold mechanism unit 1000 will be described with reference to Figs. 3 and 4. Fig. 3 and 4 are front views showing the opening state and the closing state of the mold mechanism unit 1000, respectively.

As shown in Figs. 3 and 4, the mold mechanism unit 1000 includes two molding dies 11 and 12 stacked and arranged in the vertical direction. The molding die 11 includes an upper mold 11A and a lower mold 11B and the molding die 12 includes an upper mold 12A and a lower mold 12B.

The mold mechanism unit 1000 includes an upper fixing plate 13 for fixing the upper mold 11A of the molding die 11 and a lower fixing plate 13 for fixing the upper mold 11B and the molding die 12 of the molding die 11, An intermediate plate 14 for fixing the upper mold 12A, a slide plate 15 for fixing the lower mold 12B of the molding die 12, and a lower plate 16 A lower fixing plate 17 provided below the lower plate 16, a connecting member 18 connecting the intermediate plate 14 and the lower plate 16, And a post (19) connecting the half (17).

The intermediate plate 14 and the slide plate 15 are vertically movable with respect to the upper fixing plate 13 and the lower fixing plate 17. The lower plate 16 connected to the intermediate plate 14 and the slide plate 15 are driven in the vertical direction by the toggle link mechanism 10 provided below the slide plate 15. [ Thereby, switching between the opening state (Fig. 3) and the closing state (Fig. 4) of the molding dies 11 and 12 is performed.

The toggle link mechanism 10 includes a link member 10A (first link member) for moving the slide plate 15 and a second link member 10B having a half length with respect to the link member 10A, A link member 10B (second link member) for moving the plate 14, a link member 10C (third link member) to which the link members 10A and 10B are connected, a link member 10C And a link member 10D (fourth link member) for connecting the ball screw 10F and the ball screw 10F. The closing forces of the molding dies 11 and 12 are transmitted to the intermediate plate 14 and the slide plate 15 through the ball screw 10F and the link members 10A to 10D. At this time, when the intermediate plate 14 moves by the distance L, the slide plate 15 moves by the distance 2L. Thereby, the molding dies 11 and 12 can be simultaneously closed.

One end of the link member 10C is rotatably connected to a stationary member 17A fixed to the lower fixed plate 17 and the other end of the link member 10C is connected to the link member 10A And is rotatably connected. The link member 10B is rotatably connected to the link member 10C at the midpoint between the one end and the other end.

When the insert member is compression molded from a resin material by using the mold mechanism unit 1000 shown in Figs. 1 to 4, first, the insert member and the resin material are supplied to each of the molding dies 11, 12. Next, the intermediate plate 14 is moved by the distance L by using the toggle link mechanism 10 provided below the slide plate with the upper mold 11A of the molding die 11 fixed thereon And the slide plate 15 is moved by the distance 2L to apply a closing force to the molding dies 11 and 12.

The mold mechanism part 1000 is assembled in an atmosphere of normal temperature (cold state). At this time, as shown in Fig. 4, the die heights 40 (the heights of the molding dies 11 and 12) of the molding dies 11 and 12 are adjusted.

When the compression molding is performed using the molding dies 11 and 12 fitted with the die heights 40, the molding dies 11 and 12 are heated (heated). Here, since the mechanisms and the respective parts of the mold mechanism unit 1000 thermally expand with different thermal expansion coefficients, the die heights of the molding dies 11 and 12 become different. In the mold mechanism unit 1000, the die height is adjusted by using the parallelism adjusting mechanism 100 described later.

5 and 6 are enlarged views showing the structure of the toggle link mechanism 10 in the opening state and the closing state of the molding dies 11 and 12, respectively. In the step of applying the closing force to the molding dies 11 and 12, the ball screw 10F is operated from the opening state of the molding dies 11 and 12 shown in Fig. 5, The link members are rotated.

7, a triangle including a link member 10A for moving the slide plate 15 and a link member 10B for moving the intermediate plate 14 through the lower plate 16, Is deformed in a state of maintaining a 2: 1 ratio of similarity in which the link member 10C is a common side. Thereby, the intermediate plate 14 can be moved by the distance L while the slide plate 15 is moved by the distance 2L.

In the above-described compression molding apparatus, since the space below the slide plate 15 is effectively used and the toggle link mechanism 10 is provided, the footprint of the mold mechanism unit 1000 is reduced, .

As one modification, it is conceivable to set the ratio of the length and the moving distance of the link member 10A to the length and the moving distance of the link member 10B to 3: 1, as shown in Fig. For example, in the case where the molding dies 11 and 12 have different sizes or when the molding dies 11 and 12 have different sizes, a modification of Fig. 8 can be used.

As another modification, two lower plates 161 and 162 and link members 10B1 and 10B2 connected thereto are provided as shown in Fig. 9, and three molding dies are provided together with the slide plate 15 It is also considered to laminate. 9, while the lower plate 161 is moved by the distance L, the lower plate 162 is moved by the distance 3L, and the slide plate 15 is moved by the distance 4L. As described above, in a device in which a desired number of molds for compression molding are arranged in layers, the link member 10C is divided into a desired number, and the link member is pin- The mold can be closed.

3 to 9, for convenience of illustration and explanation, the link members 10A to 10D are drawn as one line, but actually, the link members 10A to 10D are plate-shaped members.

In the mold mechanism portion 1000 according to the present embodiment, the parallelism adjusting mechanism 100 is provided on each of the four connecting members 18 in order to adjust the parallelism of the mold surfaces of the molding dies 11 and 12 .

10 is a cross-sectional view showing the structure of the parallelism adjusting mechanism. 10, the parallelism adjusting mechanism 100 includes adjusting members 100A and 100B attached to each of two divided connecting members 18A and 18B and a plurality of adjusting members 100A and 100B And a shaft 100C provided. The adjusting members 100A and 100B are provided with a pair of housings 110A and 110B, lids 120A and 120B, locknuts 130A and 130B, up and down moving bodies 140A and 140B, 150B, and threaded portions 160A, 160B. A hexagonal hole portion 170 is formed in the shaft 100C.

The locknuts 130A and 130B and the vertical moving bodies 140A and 140B are screwed to the threaded portions 160A and 160B. The threaded portions 160A and 160B are formed by male threads in the same direction with different pitches. For example, the threaded portion 160A is a male thread M10, and the threaded portion 160B is a male thread M16. By forming the male screw in the same direction with different pitches in this manner, the clearance (G shown in Fig. 10) between the adjustment members 100A and 100B can be adjusted when the shaft 100C is rotated. The shaft 100C can be rotated by inserting a hexagonal wrench into the hexagonal hole 170. [ This operation can be performed, for example, in the direction of an arrow shown in Fig. 2 as " unadjusted ", that is, in a direction orthogonal to the direction in which a plurality of molding units A are arranged. The in-loader unit B, and the out-loader unit C without separating them.

As another configuration, the threaded portions 160A and 160B can be made of the male thread having the same diameter (for example, M10) in the reverse direction. However, since the adjustment amount of the clearance G per one rotation of the shaft 100C can be made small by using the pitch difference of the male screw in the same direction, it is possible to make a small adjustment of the clearance G It becomes possible.

It is possible to adjust the surface parallelism in the molding dies 11 and 12 by adjusting the clearance between the adjusting members 100A and 100B in the plurality of parallelism adjusting mechanisms 100. [ In the compression molding apparatus according to the present embodiment, since the mold surface parallelism can be adjusted without separating the molding unit A, the in-loader unit B and the out-loader unit C, It is possible to sufficiently improve the performance.

1 to 4, the adjustment mechanism 100 is separately provided for the four posts 19, and four adjustment mechanisms 100 are provided.

When there is a difference in the thickness of the insert parts in the molding dies 11 and 12 (for example, in the case of molding other parts or in the case of the same type of parts, there is a variation in thickness of each board) The springs 150A and 150B are provided on the adjusting members 100A and 100B. Figs. 11 and 12 show a state in which the difference in thickness of the members molded by the molding dies 11 and 12 is absorbed. The elastic deformation of the springs 150A and 150B absorbs the difference in the thickness of the insert parts in the molding dies 11 and 12 so that a desired closing force can be applied to the molding dies 11 and 12 .

More specifically, when there is a difference in thickness of the members supplied to the molding dies 11 and 12, since the connecting member 18B is fixed to the toggle link mechanism 10, The intermediate plate 14 moves up and down to absorb the thickness difference. The gap 41 is generated in the adjusting members 100A and 100B having the thinner members since the thicker member is fixed first and the thinner member is fixed after the member is moved to the closing state . In the case of the example shown in Fig. 11, since the thickness of the insert part on the side of the lower adjusting member 100B is thin, a gap 41 is generated on the side of the lower adjusting member 100B. In the case of the example shown in Fig. 12, since the thickness of the insert part on the side of the upper adjusting member 100A is thin, the gap 41 is generated on the side of the lower adjusting member 100A.

Further, the adjustment mechanism 100 can be used to adjust the die height in the same manner as the adjustment of the surface parallelism. According to the compression molding apparatus of the present embodiment, since the die height can be adjusted without separating the molding unit A, the in-loader unit B, and the out-loader unit C, It is possible to sufficiently improve the performance.

13 is a view showing a modification of the mold mechanism portion. A structure including the pressing mechanism 200 and the pinion 18α and the racks 18β1 and 18β2 may be used instead of the toggle link mechanism 10 as in the mold mechanism portion 2000 shown in FIG. The pressing mechanism 200 moves the intermediate plate 14 and the pinion 18α connected thereto by the distance L and accordingly the rack 18β2 and the slide plate 15 move by the distance 2L.

In this modification, it is also possible to adjust the degree of parallelism of the die surfaces of the molding dies 11, 12 or adjust the die height by providing the adjustment mechanism 100. [

In the above-described example, the compression molding apparatus including the four posts 19 and the four adjustment mechanisms 100 has been described, but the scope of the present invention is not limited thereto. For example, the number of adjustment mechanisms 100 may be arbitrarily changed. The structure of the post 19 is not limited to that described above. For example, as in the case of the mold mechanism portion 3000 shown in Figs. 14 and 15, The frame 19A may be provided. In this case as well, the adjusting mechanism 100 includes the adjusting members 100A and 100B provided on each of the two divided connecting members 18A and 18B and the shaft 100C provided on the adjusting members 100A and 100B ).

While the embodiments of the present invention have been described above, it should be understood that the embodiments disclosed herein are illustrative and non-restrictive in all respects. It is intended that the scope of the invention be indicated by the appended claims and that all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
