Abstract
An automatic assembly tool can be used to perform placement of a conductive wire material that passes through a plurality of surfaces in a power feed path unit, thus enabling reduced costs and improved assembly productivity for the power feed path unit.
Claims9
A power feed path unit having a plurality of surfaces that forms a predetermined angle and in which power feed path unit an automatic assembly tool is used to place a conductive wire material on the plurality of surfaces so as to configure an electrical connecting path,
- the power feed path unit including:
- a wire fixing portion configured to fix the end of the conductive wire material;
- and
- a groove portion that is formed continuously so as to pass through the plurality of surfaces and that forms a path for placement of the conductive wire material that is fixed to the wire fixing portion.
An image forming apparatus, comprising:
- a device main body in which an image forming unit is removably mounted;
- a high-voltage unit that is provided to the device main body and that is configured to supply a voltage to the image forming unit mounted in the device main body;
- and
- a power feed path unit that is provided in the device main body and that configures a path which electrically connects the high-voltage unit to the image forming unit and which supplies the voltage from the high-voltage unit to the image forming unit, the power feed path unit having a plurality of surfaces that forms a predetermined angle and in which power feed path unit an automatic assembly tool is used to place a conductive wire material on the plurality of surfaces so as to configure an electrical connecting path,
- wherein the power feed path unit includes:
- a wire fixing portion configured to fix the end of the conductive wire material;
- and
- a groove portion that is formed continuously so as to pass through the plurality of surfaces and that forms a path for placement of the conductive wire material that is fixed to the wire fixing portion.
An assembly method for a power feed path unit in which an automatic assembly tool is used to place a conductive wire material in the power feed path unit so as to configure an electrical connecting path,
- the assembly method placing the conductive wire material in the power feed path unit so as to configure the electrical connecting path by:
- using an arm of the automatic assembly tool to wind and fix the conductive wire material around a wire fixing portion of the power feed path unit which is fixed to a fixing rack of the automatic assembly tool;
- routing the conductive wire material, which has been fixed by the arm to the wire fixing portion, to a first surface among a plurality of surfaces of the power feed path unit;
- in order to cause a second surface, which forms a predetermined angle relative to the first surface among the plurality of surfaces of the power feed path unit, to face the arm:
- rotating the fixing rack through the predetermined angle;
- and
- continuously routing the conductive wire material, which has been fixed by the arm to the wire fixing portion, from the first surface to the second surface.
