Abstract

An assembling apparatus configured to mount a first part on a second part having an engaged part extending in a first direction includes a holding part configured to hold the first part, an engaging part extending in the first direction and being configured to engage with the engaged part, a support part configured to support the holding part and the engaging part, a first mechanism configured to displace the support part in the first direction, and a second mechanism configured to allow a displacement of the support part in a plane intersecting with the first direction.

First claim

What is claimed is:

1. An assembling method for assembling a first part to a second part using an assembling apparatus, the assembling apparatus including a holding part with gripping members, an engaging part which extends in a first direction and includes a first pin and a second pin, a support member which supports the holding part, a first mechanism which movably supports the support member in the first direction, a second mechanism which movably supports the first mechanism in a first plane intersecting with the first direction, a third mechanism, and a control part, said method comprising:
holding the first part by moving the gripping members of the holding part relative to the support member and the engaging part in a second plane parallel to the first plane such that the gripping members hold the first part,
positioning the holding part relative to a second part in the second plane by engaging the engaging part extending in the first direction with an engaged part being formed on the second part and extending in the first direction while the first mechanism moves the support member in the first direction and the second mechanism allows the first mechanism to move in the first plane;
mounting, after the positioning, the first part held by the holding part on the second part while the first mechanism further moves the support member in the first direction; and
releasing the holding of the first part mounted on the second part,
wherein, in the positioning, the control part controls the third mechanism so as to move away from the first mechanism so that the engaging part is allowed to displace in the second plane,
wherein, in the mounting, the control part controls the third mechanism to move toward the first mechanism so as to physically restrict displacement of the support member, and
wherein, in the positioning, the first pin and the second pin of the engaging part engage with a first cylindrical hole and a second cylindrical hole of the engaged part, respectively, a diameter of the first cylindrical hole being larger than a diameter of the second cylindrical hole.

2. The assembling method according to claim 1 ,
wherein the first part is a semiconductor light emitting device that is provided in a lighting device to be mounted on a vehicle, and
wherein the second part is a support body configured to support the semiconductor light emitting device.

3. The assembling method according to claim 1 ,
wherein the control part controls the third mechanism to move toward and away from the first mechanism in the first plane intersecting with the first direction.

4. The assembling method according to claim 1 ,
wherein in the positioning, the holding part is moved in the second plane while the engaging part moves to follow a shape of the engaged part.
