Provided is a composite material bonding apparatus that can reduce a cycle time when composite material members are bonded to each other. The composite material bonding apparatus includes a sheet-heater moving device that places a graphite heater at an insertion position between a first bonded surface of a first composite material member and a second bonded surface of a second composite material member such that the graphite heater is parallel to the first bonded surface and the second bonded surface facing the first bonded surface, and retracts the graphite heater to a retraction position from the insertion position. The first bonded surface and the second bonded surface are heated at the insertion position by the graphite heater, and then the graphite heater is moved to the retraction position by the sheet-heater moving device.

A component production method includes: a step of binding a long frame by a plurality of support devices arranged along the frame; a step of measuring, with a distance sensor, a distance to the frame supported by the plurality of support devices; a step in which, based on frame shape data prerecorded in a memory, the support devices move support positions where the frame is supported so that a calculated radial position of the frame being supported by the support devices matches the data about the frame shape; a step of fixing the frame in a state in which the data about the frame shape matches the radial position of the frame; and a step of performing a hole-making operation on the fixed frame.

An ophthalmic device comprising a light source to emit fixation target light, and a reflecting face to reflect scanning light emitted by an emission section and scan the scanning light in a specific direction by changing orientation, the emission section being a scanning light source different to the light source. A concave mirror face is disposed so scanning light reflected by the reflecting face is incident on a subject's eye ocular fundus when the eye is at the concave mirror's focal point, and is arranged such that, when the eye is at the concave mirror's focal point, and when the light source emits fixation target light, that light and scanning light are simultaneously incident on the ocular fundus via different optical paths propagating via the concave mirror face and focal point, the target fixation light following a predetermined optical path for fixing the subject's eye gaze.

A transport jig includes: a frame member; and a support section that is installed on the frame member and that supports a plurality of elongated members. The elongated members are each entirely housed inside the frame member in a lengthwise direction and the support section supports the plurality of elongated members in parallel with one another in one direction.

A component manufacturing method includes a step of calculating, for a plurality of keyholes formed on a skin and disposed in a row along a first axial direction on the skin, a first imaginary line that passes an average position in a second axial direction perpendicular to the first axial direction and is parallel to the first axial direction, a step of calculating, for a plurality of keyholes formed on a frame and disposed in a row along a third axial direction on the frame, a second imaginary line that passes an average position in a fourth axial direction perpendicular to the third axial direction and is parallel to the third axial direction, and a step of superimposing the skin and the frame such that the first imaginary line and the second imaginary line coincide.

Component manufacturing method and component manufacturing system

A component manufacturing method includes a step in which a robot for attachment gripping a long frame presses the frame against a tabular skin and a step in which, in a state in which the frame is pressed against the skin, a robot for riveting gripping a first rivet inserts the first rivet into a first through-hole formed in the skin and a second through-hole formed in the frame. In the step, the robot for riveting changes a position in the gripped first rivet in a direction perpendicular to an axial direction of the first rivet according to a force received by the first rivet from the skin or the frame.

To facilitate mounting of a second member on a first member having a plate shape while the first member is supported in a state of being deformable due to gravity. A method for manufacturing a component includes: a step (S) where a supporting robot supports a skin having a plate shape in a state where the skin is deformable due to gravity, and a support state of the skin is changed based on teaching data based on a deformed shape of the skin, which is recorded in advance in a storage unit and which is obtained at the time of mounting a frame on the skin; and a step (S) where a mounting robot makes the frame overlap with the skin where a support state is changed.
