Method for manufacturing lens barrel

摘要

A manufacturing method of a lens barrel is disclosed. According to one implementation, the manufacturing method includes the following steps. A first lens holding section protrusion step inserts a first lens holding section from one end of a barrel frame to a hollow section to protrude from the other end. A second lens holding section suction step sucks a convex surface section. A first lens holding section contact step brings the planar surface section into contact with the first lens holding section. A lens holding switching step releases suction of the convex surface section, and the planar surface section is held by the first lens holding section. A barrel frame contact step moves the first lens holding section or the lens barrel so that a surrounding edge section is brought into contact with a lens receiving section.

1. A manufacturing method of a lens barrel in which a first lens holding section which can hold a planar surface section of a planar-convex lens and a second lens holding section which can suck a convex surface section of the planar-convex lens are used to insert the planar-convex lens in a hollow section provided in a barrel frame, the manufacturing method comprising:
a first lens holding section protrusion step in which the first lens holding section is inserted from an opening section positioned at one end of the barrel frame to the hollow section to protrude the first lens holding section from an opening section positioned at the other end of the barrel frame; a second lens holding section suction step in which the convex surface section of the planar-convex lens is sucked with the second lens holding section; a first lens holding section contact step in which the planar surface section of the planar-convex lens is brought into contact with the first lens holding section after the first lens holding section protrusion step and the second lens holding section suction step; a lens holding switching step in which suction of the convex surface section of the convex-planar lens is released by the second lens holding section, and the planar surface section of the planar-convex lens is held by the first lens holding section after the first lens holding section contact step; and a barrel frame contact step in which the first lens holding section or the lens barrel is moved in an optical axis direction of the planar-convex lens so that a surrounding edge section of the planar surface section of the planar-convex lens is brought into contact with a lens receiving section provided in the hollow section of the barrel frame after the lens holding switching step.
