Abstract

An assembling apparatus that has a mold in which a second unit opposes a first unit and that is configured to assemble an assembled product from a plurality of parts. The first unit includes first, second, and third movable portions, which comprise, respectively, a plurality of first forming portions, a plurality of second forming portions, and a plurality of third forming. The second unit comprises a fourth movable portion, a fourth forming portion, a fifth forming portion, a sixth forming portion, and a plurality of assembling portions. The fourth movable portion is configured to move so as to switch at least one assembling portion opposed to at least one first forming portion, at least one other assembling portion opposed to the at least one second forming portion, and at least one remaining assembling portion opposed to at least one third forming portion.

First claim

What is claimed is:

1. An assembling apparatus configured to assemble an assembled product from a plurality of parts, the assembling apparatus comprising:
a mold comprising a first unit and a second unit opposing the first unit,
wherein the first unit comprises a first movable portion that is movable, a second movable portion, and a third movable portion, the first movable portion comprising a plurality of first forming portions, the second movable portion comprising a plurality of second forming portions, and the third movable portion comprising a plurality of third forming portions,
wherein the second unit comprises a fourth forming portion, a fifth forming portion, a sixth forming portion, and a plurality of assembling portions,
wherein the first movable portion is configured to have at least one first forming portion of the plurality of first forming portions oppose at least one assembling portion of the plurality of assembling portions, and to have at least one remaining first forming portion of the plurality of first forming portions oppose the fourth forming portion,
wherein the second movable portion is configured to have at least one second forming portion of the plurality of second forming portions oppose at least one other assembling portion of the plurality of assembling portions, and to have at least one remaining second forming portion of the plurality of second forming portions oppose the fifth forming portion,
wherein the third movable portion is configured to have at least one third forming portion of the plurality of third forming portions oppose at least one remaining assembling portion of the plurality of assembling portions, and to have at least one remaining third forming portion of the plurality of third forming portions oppose the sixth forming portion, and
wherein the second unit further comprises a fourth movable portion, and the fourth movable portion is configured to move so as to switch the at least one assembling portion of the plurality of assembling portions opposed to the at least one first forming portion of the plurality of first forming portions, the at least one other assembling portion of the plurality of assembling portions opposed to the at least one second forming portion of the plurality of second forming portions, and the at least one remaining assembling portion of the plurality of assembling portions opposed to the at least one third forming portion of the plurality of third forming portions.

2. The assembling apparatus according to claim 1 , wherein the first movable portion comprises a rotatable board.

3. The assembling apparatus according to claim 2 , wherein the rotatable board is one of a plurality of rotatable boards, and
wherein at least one of the plurality of rotatable boards comprises two or more first forming portions of the plurality of first forming portions.

4. The assembling apparatus according to claim 1 , wherein the fourth movable portion comprises a rotatable board.

5. The assembling apparatus according to claim 1 , wherein an assembling portion of the plurality of assembling portions not opposing any of the first forming portions, the second forming portions, and the third forming portions is exposed such that the assembled product can be taken out in a state in which the mold is clamped.

6. The assembling apparatus according to claim 1 , wherein the at least one assembling portion of the plurality of assembling portions comprises a recess portion to which one part of the plurality of parts is to be accommodated and an engagement pin that is disposed in the recess portion and engages with the one part of the plurality of parts.

7. The assembling apparatus according to claim 2 , wherein the second movable portion comprises a rotatable board.

8. The assembling apparatus according to claim 1 , wherein, by clamping the mold, a part held by the at least one first forming portion of the plurality of first forming portions is supplied to the at least one assembling portion of the plurality of assembling portions, thus assembly of the assembled product is performed, and a cavity for forming one part of the plurality of parts is defined by the fourth forming portion and the at least one remaining first forming portion of the plurality of first forming portions.

9. The assembling apparatus according to claim 8 , wherein the at least one first forming portion of the plurality of first forming portions comprises an ejector pin configured to stick out of the at least one first forming portion of the plurality of first forming portions to hold the part in the at least one assembling portion of the plurality of assembling portions as the mold goes from a closed state to an open state.

10. The assembling apparatus according to claim 2 , wherein the third movable portion comprises a rotatable board.

11. An assembling apparatus configured to assemble an assembled product from a plurality of parts, the assembling apparatus comprising:
a mold comprising a first unit and a second unit opposing the first unit,
wherein the first unit comprises a first movable portion that is movable, a second movable portion, and a third movable portion, the first movable portion comprising a plurality of first forming portions, the second movable portion comprising a plurality of second forming portions, and the third movable portion comprising a plurality of third forming portions, the plurality of the first forming portions being configured to form a plurality of first parts, the plurality of the second forming portions being configured to form a plurality of second parts, and the plurality of the third forming portions being configured to form a plurality of third parts,
wherein the second unit comprises a fourth forming portion, a fifth forming portion, and a fourth movable portion, the fourth movable portion being configured to move so as to switch a first assembling portion, a second assembling portion, and a third assembling portion,
wherein the first movable portion is configured to have at least one first forming portion of the plurality of first forming portions oppose the first assembling portion, and the first assembling portion is configured to hold a first one of the first parts formed in the at least one first forming portion of the plurality of first forming portions,
wherein the second movable portion is configured to have at least one second forming portion of the plurality of second forming portions oppose the second assembling portion in which a second one of the first parts is held, and the second assembling portion is configured to assemble a first one of the second parts formed in the at least one second forming portion of the plurality of second forming portions to the second one of the first parts held in the second assembling portion, and
wherein the third movable portion is configured to have at least one third forming portion of the plurality of third forming portions oppose the third assembling portion in which a part formed by assembling a third one of the first parts to a second one of the second parts is held, and the third assembling portion is configured to assemble a part formed by assembling the third one of the first parts to the second one of the second parts to a third part formed in the at least one third forming portion of the plurality of third forming portions.
