Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a top view of a package and lid combination device before operation, FIG. 2 is a front view of the device before operation, FIG. 3 is a side view of the device before operation, and FIG. 4 is a top view of the device during operation. 5 is a front view of the apparatus during operation, and FIG. 6 is an enlarged view of a circle A in FIG. FIG. 7 is an enlarged partial top view of the positioning jig set in the apparatus, FIG. 8 is an enlarged partial sectional view of the positioning jig, and FIG. 9 is a schematic diagram for explaining the installation position of the combination apparatus.
[0010]
The package and lid combination device 1 according to this embodiment is incorporated in a production line installed in a gas chamber 2 filled with a specific gas such as nitrogen gas or argon gas.
[0011]
As shown in FIGS. 1 to 3, the combination device 1 has two support columns 4 standing on a base 3 and a single support shaft 5 spanned between the support columns 4 and 4. The vibration unit 6 is swingably supported at an intermediate position.
[0012]
A flat plate-like stage 7 is mounted on the vibration unit 6, and pin-like stoppers 8 are provided upright near two orthogonal sides at one corner of the stage 7. As shown in FIG. 2, a tilting cylinder 9 is connected to the lower surface of the stage 7 opposite to the stopper 8.
[0013]
As shown in FIGS. 1 and 2, the vibration unit 6 includes two vibration cylinders 10a and 10b that vibrate the positioning jig 11 or the stage 7 in the plane direction (X and Y directions), and a positioning jig. 11 or a vibration cylinder 10c that vibrates the stage 7 in the thickness direction.
[0014]
As shown in FIGS. 7 and 8, the positioning jig 11 also serving as a conveying jig placed on the stage 7 is formed with a large number of storage recesses 12 aligned in a square shape, and each of the storage recesses 12 A gas ejection hole 13 is provided at the bottom (see FIG. 8).
[0015]
In each storage recess 12 of the positioning jig 11, a package 14 made of, for example, a ceramic package on which electronic components are mounted is stored with its opening facing upward (see FIG. 8), and the lid is placed on the package 14 15 is placed. The planar shape and width of the package 14 and the lid 15 are designed to be almost the same. The package 14 and the lid 15 are automatically loaded by, for example, a parts feeder. The size of the plane of the storage recess 12 is slightly larger than the package 14 and the lid 15, and the depth of the storage recess 12 is designed to be slightly deeper than the total height of the package 14 and the lid 15.
[0016]
The package 14 and the lid 15 are respectively stored in the storage recesses 12 in the previous step. In this state, the package 14 and the lid 15 are not fitted, and both are random as shown in FIGS. Is in a state.
[0017]
As shown in FIGS. 1 to 3, the combination apparatus 1 before the operation is such that the stage 7 is in a horizontal state, and a positioning jig 11 in which a package 14 and a lid 15 are housed in each housing recess 12 is placed on the stage 7. Automatically transport to. Next, the tilting cylinder 9 is extended, and the stage 7 is tilted about 30 to 45 °, for example, with the support shaft 5 as the center. The stroke of the tilt cylinder 9 ensures an appropriate tilt angle of the stage 7. Since the positioning jig 11 is supported by the stoppers 8 and 8, the positioning jig 11 does not fall off the stage 7 even if it is inclined.
[0018]
In this inclined state, the vibration unit 6 (vibration cylinders 10a to 10c) is driven to apply a slight vibration to the positioning jig 11 for a short time. As a result of this vibration, the package 14 and the lid 15 are moved toward the positioning corner 16 on the lower side in the housing recess 12 as indicated by an arrow in FIG. The lid 15 is automatically fitted into the opening of the package 14 and then the opening is sealed. When the package 14 and the lid 15 are positioned, a part of the lid 15 is shaped so as to be easily fitted into the opening of the package 14.
[0019]
In the case of this embodiment, the combination apparatus 1 is operated in the gas chamber 2 that maintains a predetermined gas pressure (positive pressure) as shown in FIG. There is a concern that the vibration of the package 14 is suppressed by being pressed slightly. Therefore, as shown in FIG. 8, the same gas G as the gas in the gas chamber 2 is blown from the bottom of the housing recess 12, and the package 14 and the lid 15 are positioned with the package 14 slightly lifted from the bottom of the housing recess 12. Yes. In this way, the package 14 and the lid 15 can be smoothly fitted without being affected by the gas pressure in the gas chamber 2. It should be noted that the depth of the storage recess 12 is designed so that the lid 15 is in the storage recess 12 even when the package 14 is lifted. In addition, it is designed so that the package 14 and the lid 15 do not pop out by the holding lid 18 provided with the gas vent hole 17.
[0020]
Next, the stage 7 is returned to the original horizontal state, the positioning jig 11 is discharged from the stage 7, and the fitted package 14 and lid 15 are taken out from the positioning jig 11.
[0021]
In the above embodiment, the four pin-shaped stoppers 8 and 8 are provided on the stage 7, but the planar shape supporting one corner of the positioning jig 11 may be a substantially L-shaped stopper.
[0022]
In the said embodiment, although the vibration unit 6 provided with the cylinders 10a-10c for vibration was used, you may use the vibration unit of the other type which uses an electromagnetic vibrator etc., for example.
[0023]
In the above embodiment, the stage 7 is tilted or returned to the horizontal state using the tilting cylinder 9, but the positioning jig 11 is set directly on the tilted stage 7 without using the tilting cylinder 9. Then, the positioning jig 11 may be taken out from the stage 7 that is inclined after the vibration is applied.
[0024]
In the above-described embodiment, the lid 14 is placed on the package 14 facing down. However, the lid 14 may be placed on the lid 15 facing down.
[0025]
【The invention's effect】
According to the first and third aspects of the present invention, large-scale facilities such as an image recognition device (image processing device) such as a CCD camera, a chucking mechanism, and a positioning mechanism are unnecessary, and the equipment investment is reduced. Can be planned. Further, the apparatus can be reduced in size and space can be saved. Furthermore, since a large number of packages and lids can be processed at the same time, the production efficiency can be improved.
[0026]
According to the structure of Claim 2 and Claim 4 of this invention, it has the characteristics that a package and a lid can be smoothly fitted also in the atmosphere under pressure.
