Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a multi-stackable magazine for storing components such as semiconductor integrated circuits.

(Prior art) In the assembly of semiconductor integrated circuits, a plurality of devices in the assembly process are stored in a tray or magazine and transported to successive processes, and in the processing process, the devices are removed one by one from the transported tray or magazine. This is done by extracting and processing. Particularly in the case of semiconductor integrated circuits, in which leads are attached and resin-sealed in the previous process, a plurality of semiconductor integrated circuits 1 are stored in a magazine 3 in which one storage groove 2 is formed, as shown in FIG. In the inspection process, the magazine 3 is set in an inspection device, and the semiconductor integrated circuits 1 are taken out one by one from one end of the magazine 3 and inspected. After the inspection is completed, they are transferred to another magazine again. This is done by storing and transporting.

Such a magazine 3 is, for example, published in Japanese Unexamined Patent Application Publication No. 1983-
It is disclosed in Publication No. 159099. However, with such a magazine 3, the number of semiconductor integrated circuits that can be stored in one magazine 3 is small, and a large number of magazines 3 are required. There is also a problem.

In order to solve the above problems of the conventional magazine 3, the present inventor formed a plurality of storage grooves 6 in parallel on the upper surface of the plate-like substrate 5 to store semiconductor integrated circuits, as shown in FIG. In order to prevent the semiconductor integrated circuits housed in each of the storage grooves 6 from undesirably escaping, a magazine was designed and manufactured which has a movable stopper 7 at one end of the plate-like substrate 5 that can be stopped and released.

However, since the movable stopper 7 of this magazine protrudes above the top surface of the plate-shaped substrate, when this magazine is transported to the inspection process, it cannot be stacked and transported as it is, but is transported one by one. I had to.

(Problems to be solved by the invention) As mentioned above, conventional magazines for semiconductor integrated circuits not only have a small storage capacity and require a large number of magazines, but also have problems with unmanned transportation and automatic transfer. be. In order to solve this problem, the inventor
We designed and manufactured a magazine with multiple storage grooves in parallel.

However, in order to automate the assembly of semiconductor integrated circuits and improve production efficiency, magazines are stacked in multiple stages using automatic transfer equipment or robots, and transported automatically. It is desirable to automatically separate the magazines one by one from the upper or lower tier, set them in each device, stack them again, and transport them to the next process, but the above-mentioned magazines do not have a positioning structure for stable stacking, and It was found that because of the protruding parts as mentioned above, it was not possible to stack and transport them, and that they were not suitable for automation.

The purpose of this invention is to construct a magazine that can be stacked in multiple stages and that can be unmannedly transported or automatically transferred while stacked.

[Structure of the idea]

(Means for Solving the Problem) In a magazine for storing parts, a plurality of storage grooves are formed in parallel on the upper surface of a plate-like base so that stored parts can be taken out from one end, and the above-mentioned storage grooves are formed on both sides of the plate-like base. A stopper that prevents components stored in the plurality of storage grooves from escaping from one end thereof is rotatably supported, and a V is formed on the lower surface of the plate-shaped base so as to cross the lower surface of one end of the plate-shaped base corresponding to the stopper.
A letter-shaped groove was formed. Further, a rib protruding upward is formed along both edges of the upper surface of the plate-shaped substrate, and a groove-shaped notch is formed along both edges of the lower surface of the plate-shaped substrate corresponding to the rib. Adjacent to the groove-shaped notch, a tapered portion was formed on the lower surface of the plate-shaped substrate so that the side surfaces of the plate-shaped substrate were wide open.

(Function) As described above, by forming a plurality of storage grooves in parallel on the plate-shaped base, a large number of parts can be stored in one magazine. Moreover, a V-shaped groove is formed on the lower surface of one end of the plate-shaped base in correspondence with the stopper, and ribs are formed along both edges of the upper surface of the plate-shaped base, and groove-shaped grooves are formed along both edges of the lower surface of the plate-shaped base. By forming the notch, the V-shaped groove on the bottom surface of the stacked upper magazines engages with the movable stopper of the lower magazine as a guide surface, thereby positioning the lower magazine in the vertical direction. The tapered part of the upper magazine is used as a guide surface for the rib, and the groove-like notch of this upper magazine is engaged with the rib to perform lateral positioning, and this positioning enables unmanned transport and automatic transfer. Stable multi-level stacking can be easily performed. In this case, the tapered portion formed on the lower surface facilitates multi-tier stacking.

(Example) This invention will be described below based on an example with reference to the drawings.

FIG. 1 shows the construction of a magazine for storing resin-sealed semiconductor integrated circuits, which is an embodiment of the invention, and FIG. 2 shows an enlarged view of the main parts of the magazine.
This magazine has a plate-like base body 5 made of drawn aluminum material, and a plurality of storage grooves 6 are formed in parallel along the side edges on the upper surface of the base body 5. Each of the storage grooves 6 is open at both ends of the plate-like substrate 5, and has a cross-sectional shape such that a platform portion 10 that supports a resin molded portion of a semiconductor integrated circuit and a lead led out from the resin molded portion are inserted. The semiconductor integrated circuits housed are formed in a U-shape with slits provided on both sides of the platform part 10 so that the semiconductor integrated circuits housed in the bulkhead 11 are formed between adjacent housing grooves. The structure is such that it does not allow the material to escape in a direction perpendicular to the board surface.

Further, on both side edges of the upper surface of the plate-shaped base 5, ribs 13 are provided which protrude upward perpendicularly to the plate surface along the side edges.
is provided. In addition, groove-shaped cuts are formed along the side edges on both sides of the lower surface in a shape corresponding to the ribs 13, which engage and position the ribs 13 provided on the lower magazine when the magazines are stacked. A notch 14 is provided, and the grooved notch 1
A tapered portion 15 that opens toward the side surface of the plate-like substrate 5 is provided adjacent to the plate-like substrate 4 . When stacking magazines, this tapered part 15 comes into contact with the rib 13 of the lower magazine to correct the lateral shift of the upper magazine to be stacked. I will guide you to.

Further, at one end of the upper surface of the plate-shaped base 5, the plate-shaped base 5 A movable stopper 7 is provided across the top surface. This movable stopper 7 has both ends rotatably supported on both sides of the plate-shaped base 5 as shown by arrow A, and as shown in FIGS. 1 and 2,
When the plate-shaped base 5 is tilted forward toward one end side, at least a portion of the plate-shaped base 5 engages with the notch 17 provided in the rib 13 so as to protrude above the upper surface of the plate-shaped base 5, and is attached to the movable stopper body. A plurality of tongue pieces 18 provided
is inserted into each storage groove 6 to prevent the semiconductor integrated circuit stored in each storage groove 6 from escaping from the opening at one end. Further, by rotating the plate-shaped base 5 toward the other end, the blocking can be released. Further, in correspondence with the movable stopper 7, a groove 19 having a V-shaped cross section is provided on the lower surface of the plate-shaped base 5 so as to cross the plate-shaped base 5. When stacking magazines, this V-shaped groove 19 is used to prevent the movable stopper 7 of the lower magazine from being tilted forward.
Corrects vertical misalignment of magazines that come in contact with and stack.

A plurality of resin-sealed semiconductor integrated circuits are inserted into each storage groove 6 from one end opening of the storage groove 6 with the movable stopper 7 tilted toward the other end of the plate-like base 5. The fixed stopper 16 provided at the other end and the movable stopper 7 tilted forward prevent escape from the openings at both ends.

This stacking of magazines is automatically done by a transfer device or robot, but at this time,
The ribs 13 and groove-like notches 14 provided on the plate-like base 5 correct the lateral displacement of the magazines to be stacked and position them, and the tapered part 15 acts as a guide to facilitate the positioning. . Further, the movable stopper 7 and the V-shaped groove 19 similarly correct the vertical displacement for positioning.

That is, when stacking magazines in multiple stages as shown in FIG. 3, if the upper magazine to be stacked is misaligned with respect to the lower magazine, the tapered part 15 of the upper magazine will touch the rib 13 of the lower magazine. The groove-shaped notch 14 provided adjacent to the tapered portion 15 is aligned with the rib 1 to correct the lateral displacement of the upper magazine along its tapered surface.
3 and engage it. At the same time as this lateral guide positioning, the V-shaped groove 19 of the upper magazine
The forward-inclined movable stopper 7 of the lower magazine comes into contact with the movable stopper 7, corrects the vertical displacement of the upper magazine along its tapered surface, and guides the upper magazine in the vertical direction until it properly engages with the movable stopper 7. Thus, the rib 13 and movable stopper 7 of the lower magazine, and the groove-shaped notch 14 and V-shaped groove 19 of the upper magazine, allow the magazine to be correctly positioned and placed on the lower magazine.

This invention also applies to components other than semiconductor integrated circuits, as long as the gist remains unchanged.
Can be easily applied.
