Description

  The present application belongs to a technical field of a component positioning mechanism and a component positioning method for positioning various components such as an electrical component, an electronic component, or an optical component.

  Conventionally, for example, in the opening of an exterior panel in an electronic component, a hole through which an operation portion of a push button member such as a push button is inserted and a protective member for protecting the operation portion is positioned. Positioning was performed such that the hole of the protective member communicated with the opening of the panel. After the protective member is positioned and fixed, the operation portion of the push button member is inserted into the hole of the protective member and the opening portion of the exterior panel, and the operation portion slightly protrudes from the front surface of the opening portion of the exterior panel. Thus, the push button member is temporarily fixed to the exterior panel.

As a result, in order to accurately position the protective member on the exterior panel, a troublesome and time-consuming work is required, and the problem of poor positioning work efficiency is given as an example.

  Therefore, the present application has been made in consideration of the above circumstances, and an example of the problem is to provide a component positioning mechanism and a component positioning method capable of positioning various components accurately and easily.

  In order to solve the above problem, the invention according to claim 1 is a component positioning mechanism for positioning the second component on the first component, and the XY coordinates of the first component and the second component A first positioning member that positions the center of the plane at the same position; and a second positioning member that positions the angle in the rotation direction of the second component at the same angle with respect to the first component. It is characterized by that.

  Moreover, in order to solve said subject, invention of Claim 8 is the components positioning method which positions a 2nd component in a 1st component, Comprising: A said 1st component and a said 2nd component A first positioning step for positioning the center in the XY coordinate plane at the same position; and a second positioning step for positioning the angle in the rotation direction of the second component at the same angle with respect to the first component. It is characterized by having.
