Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a method for storing integrated circuit circuit boards during the manufacture of hybrid integrated circuits, etc., and sending the circuit boards individually to processes such as wire bonding. The present invention relates to the structure of a magazine for storing hybrid integrated circuits, etc. after completion of the process.

(b) Prior art In the manufacturing process of hybrid integrated circuits, in which circuit elements are formed on a substrate made of alumina or the like, and individual circuit elements are further mounted on the substrate, for example, when the circuit elements are mounted on the substrate, In processes such as wire bonding mounted circuit elements to circuit board circuits, a plurality of boards are supplied to a carrier from a magazine mounted in front of the work table, and the boards are loaded onto a carrier. Processes such as bonding are performed on the work table, and if necessary, a magazine is provided on the outlet side of the work table, and the processed substrates are stored in the magazine together with the carrier. For this reason, the magazine has a plurality of storage sections in which a plurality of carriers can be stored.

The conventional structure of a magazine for storing substrates placed on such a carrier is shown in FIGS. 1 and 2.
The figure is a perspective view of a magazine that accommodates substrates with substrates placed on the carrier, and FIG. 2 is a perspective view of the magazine with substrates placed on the carrier.

In FIG. 1, a magazine 1 has a pair of side plates 2
, an upper plate 3 that fixes the upper ends of the pair of side plates 2 at a predetermined interval, a lower plate 4 that fixes the lower ends of the pair of side plates 2 at a predetermined interval, and a plurality of carriers (seven in the figure). It consists of 5. The pair of side plates 2 have a plurality of horizontal grooves 6 (seven in the figure) with a U-shaped cross section on their opposing surfaces.
Each opposing groove 6 supports an end portion of the carrier 5 in the width direction.

In Figures 1 and 2, multiple images (the figure shows 4
The carrier 5 on which 24 boards 7 are placed has a plurality of boards 7 (24 boards shown in the figure) for positioning each board 7 at equal intervals.
A plurality of (10 in the figure) through holes 9 are drilled near the ends in the width direction for feeding and positioning the carrier 5.

In order to sequentially supply carriers loaded with substrates from the magazine 1 configured in this way to a work table (for example, a bonding table), the magazine is fixed to a movable table that moves up and down at a position on the entrance side of the work table. Ru. When the lowest carrier of the magazine is flush with the work table, the carrier is pushed out of the groove 6 by a pusher (not shown) and placed on the work table (also not shown). On the worktable, the carrier is moved by a control pin inserted into its through hole 9 at intervals corresponding to the length of the substrate, thereby performing the necessary processes on the substrate. The magazine is then lowered by the movable table and stopped at a position where the next carrier is flush with the work table. When all the processes for the substrate on the first carrier at the worktable are completed, that carrier is stored in another magazine at the outlet end of the worktable, and the next carrier is loaded from the magazine at the inlet end of the worktable. is pushed onto the worktable.

(c) Problems to be solved by the invention However, the length and width of the board 7 differ depending on its type, and in that case, the carrier stored in the magazine can also hold boards of different sizes. The carrier has the same dimensions and shape with sufficient length and width, but the position of the pin 8 and the position of the hole on the carrier are different depending on the dimensions of the substrate to be placed on it. There is.

Therefore, if the dimensions of the board 7 are the same, even if the electronic circuits and mounted elements are different, carriers with the same pin 8 installation position and the same through-hole position can be used.
On the other hand, in the case of substrates having different dimensions, carriers having pins 8 and through holes must be prepared depending on the type.

That is, the problems with conventional magazines arise from the fact that the substrates are placed on a carrier.

On the other hand, carriers are needed only for transporting substrates, and when processing on a worktable, carriers complicate control of the processing process and limit the number of substrates that can be placed on the worktable. ing.

The present invention attempts to solve the above problems by using a magazine that does not use a carrier. In that case, by not using a carrier, it is naturally necessary to change the movement control of the substrate on the work table, but as mentioned above, without using a carrier, control in the processing process is easier than before. Based on this assumption, the present invention has the same basic components and can store all types of substrates by only changing some of the configurations. Moreover, it can also be installed on the entrance side of the work table. The purpose is to create a magazine that can be attached to the outlet side as well.

(d) Means for solving the problem This object is achieved by the present invention, which is used for storing boards of hybrid integrated circuits, and consists of a pair of side plates, an upper plate, and a lower plate, and a long side plate is provided on the opposing surfaces of the side plates. A plurality of parallel substantially U-shaped horizontal grooves are formed at the same intervals in the horizontal direction, and the horizontal grooves have substantially the same depth and width corresponding to the thickness of the substrate, and the upper plate has a side plate on its lower surface. The upper end is provided with two parallel grooves on the upper surface of the lower plate into which the lower ends of the side plates are respectively inserted, and the lower plate is provided with an elongated hole into which the pusher can be inserted and moved along the center line. The intervals between the grooves on the lower surface of the upper plate and the upper surface of the lower plate are determined according to the width of the board to be inserted, and the upper end of the side plate is placed in the groove of the upper plate, and the lower end of the side plate is placed in the groove of the lower plate. This is achieved by a substrate storage magazine characterized in that the substantially U-shaped horizontal grooves of the side plates are inserted and fixed so that they can face each other.

(e) Effect According to the present invention, only the substrates are accommodated by the side plates having horizontal grooves that can accommodate various thicknesses of the substrates. A new magazine can be constructed by changing only the lower plate to one with the corresponding width, leaving the side plates as they are, and inserting the upper end into the groove on the bottom of the upper plate and the lower end into the groove on the top of the lower plate. That will happen.
Further, the pusher protrudes from below through a long hole located on the center line of the lower plate and hits perpendicularly to the rear end of the substrate, making it possible to reliably push out even thin substrates.

(f) Example of implementation of the idea The present invention will be further explained based on examples.

FIG. 3 is a partially cutaway perspective view of a magazine according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view of the lower plate of the magazine cut along the center line in the longitudinal direction.

In FIG. 3, the magazine 11 has a pair of side plates 1
2, and an upper plate 13 having a groove formed by a angular cross-section protrusion 17 and an L-shaped cross-section protrusion 18 into which the upper end portions of the pair of side plates 12 are slidably inserted and removed in the length direction thereof.
and a pair of screws 22 and 1 which face each other in the thickness direction of the side plate 12 and are screwed into the upper plate 13 in order to fix the fitting.
A lower plate 14 having a groove formed by an angular cross-section protrusion 19 and an L-shaped cross-section protrusion 20 into which the lower ends of the pair of side plates 12 are slidably inserted and removed in the length direction;
4, a pair of screws 23 face each other in the thickness direction of the side plate 12 and are screwed into the lower plate 14. In addition, a plurality of horizontal grooves 15 (7 grooves in the figure) with a substantially U-shaped cross section are cut into the inner surface of the side plate 12, and the grooves are wide enough to insert the maximum thickness of the board and can be held sufficiently. It has become deep.

In this case, the substantially U-shaped horizontal groove 16 on the inner surface of one side of the side plate 12 has an open U-shaped cross section with the lower side substantially horizontal and the upper side opening upward, as shown in the figure. It may have a similar shape. This horizontal groove is determined by the arrangement of the circuit elements on the board that supports both sides of the groove.
The shape of the groove may be a substantially U-shaped cross-section that supports the both side edges of the substrate in a slidable manner.
Further, a long hole 21 is cut in the center of the lower plate 14 in the width direction, extending almost over the entire length of the lower plate 14.

In this case, the lower plate is longer than the side plates and forms an extension, in order to movably hold the pusher 25 that pushes out the substrate as shown in FIG. But removing this extension,
The lower plate has the same length as the side plate, and the elongated hole in the lower plate is open at one end, and the pusher is separately supported at the entrance end of the lower plate so that it can be slid into the elongated hole in the lower plate. You can also do this.

The magazine is constructed by fitting the upper end of the side plate 12 into a groove formed by opposing projections 17 and 18, and fitting the lower end into a groove formed by opposing projections 19 and 20. In this case, the distance between each pair of grooves provided on the upper plate and the lower plate is determined to correspond to the width of the board to be stored.

In the magazine 11 configured in this manner, both ends of a large number of substrates 24 are inserted and held in the opposing grooves 15 and 16, and a plurality of substrates 24 are stored in multiple stages (seven stages in the figure). When the magazine 11 is fixed to a table that moves up and down, the substrates 24 are pushed upward from the bottom plate and from the right end of each plate through the elongated hole 21 as shown in FIG. The intermittent advance pushes the magazine 11 toward the right outlet side. Therefore, the board 24 stored in the magazine 11 is
As long as the width is within a range where it is supported by the grooves 15 and 16 and does not fall (for example, the difference is within 1 mm), the length is not restricted. However, in the case of storing boards with different widths, the pair of side plates is not changed, and only the upper plate 13 and lower plate 14 are changed to have a pair of grooves corresponding to the width of the boards, and the upper plate and the lower plate are changed. A new magazine can be constructed by inserting a side plate into the plate.

Furthermore, in FIG. 3, the substrates 24 stored in the magazine 11 are attached to the inlet side of the work table and fed out to the right, but the magazine 11 is attached to the outlet side of the work table and the substrates 24 are sequentially fed out. To store the magazine, you can reverse the left and right positions in the figure and place it on the exit side of the work table, or loosen the screws 23 and align the left side of the side plate with the left side of the lower plate. Alternatively, the side plate may be moved by sliding in the groove of the lower plate, and then placed as it is on the exit side of the work table. In this case, the pusher is removed from the elongated hole. In order to use the magazine on either the inlet side or the outlet side of the work table, it is advantageous to separate the extension from the lower plate. Further, since the pusher is long in the vertical direction as shown in the figure, even if the substrate is thin, it can be pushed out reliably.

(g) Effects of the invention As explained above, according to the magazine of this invention,
Since it is possible to store only the boards without using a carrier, the number of boards that can be stored increases.Moreover, even if there are multiple types of boards with different dimensions, there is no need to prepare multiple types of carriers, and only the upper and lower boards can be stored. The magazine was changed to one with a pair of grooves corresponding to the width of the board being used, and the same side plates can be used, and the side plates can be moved along the lower plate, so the magazine can be placed on the entrance side of the work table. It is used for sending out substrates, and it is placed on the exit side and can also be freely used for storing substrates taken out from the work table. In addition, the pusher for pushing out the stored board can be installed in an upright shape that passes through the long hole in the lower plate, so even thin boards can be reliably pushed out of the magazine, and the carrier can be Although the method of controlling the movement of the work table must be changed due to its non-use, the control of the processing process is simplified even in this case, and its practical effects are great.
