Component holding device and circuit board handling device

Abstract

To prevent a decline in the quality of electronic devices. [Solution] The parts holding device comprises a holding mechanism for holding parts, a first member connected to the holding mechanism, a second member that supports the first member so that it can move relative to it in a vertical direction parallel to the vertical axis, and a rotation mechanism that rotates the first member in a rotational direction about the vertical axis when the first member moves vertically relative to the second member.

Claims

A retaining mechanism for holding parts, A first member connected to the aforementioned holding mechanism, A second member supports the first member so that it can move relative to it in a vertical direction parallel to the vertical axis, The first member is rotated in a rotational direction about the vertical axis when the first member moves vertically relative to the second member, Parts holding device.

2. The aforementioned rotating mechanism is A guide groove is provided on one of the first member and the second member, and is inclined with respect to the vertical axis, A slide pin provided on the other of the first member and the second member and positioned in the guide groove, The component holding device according to claim 1.

3. At least a portion of the first member is rod-shaped, The second member has a sleeve portion into which at least a part of the first member is inserted. The guide groove is provided in the sleeve portion, The slide pin is provided so as to protrude from the outer surface of the first member. The component holding device according to claim 2.

4. When the surface of the component held by the holding mechanism is pressed against the substrate, the first member moves upward relative to the second member. The rotation mechanism rotates the first member by a predetermined angle in a first direction when the first member moves upward. The component holding device according to claim 1.

5. The first member is rod-shaped, The second member has a sleeve portion into which at least a part of the first member is inserted. The aforementioned rotating mechanism is The sleeve portion is provided with a guide groove that is inclined with respect to the vertical axis, The first member has a slide pin that is provided to protrude from the outer surface of the first member and is positioned in the guide groove, The component holding device according to claim 4.

6. The guide groove is inclined downward in a second direction opposite to the first direction. The component holding device according to claim 5.

7.
