Light irradiation device for curing and method of manufacturing electric wire module including connection part

Abstract

A light irradiating device used for curing and a manufacturing method of a wire module comprising a wiring part are provided. The light irradiating device aims to enable a light curing agent attached to the periphery of a processing object part of a wire to be cured more reliably. The light irradiating device used for curing comprises: a light irradiating part (110); a rotation support mechanism (120) for enabling the light irradiating part (110) to be rotatably supported around a processing object part of the wire (22), i.e., a wiring part, in the case of enabling a light from the light irradiating part (110) to irradiate towards the processing object part of the wire supported at a curing processing position P; and a rotation driving mechanism (130) for enabling the rotation support mechanism (120) to rotate. And preferredly, the plurality of light irradiating parts (110) are rotatably supported around the processing object part of the wire, and rotate at a rotating angle within the range less than 360 degrees.

Description

technical field [0001] The present invention relates to a technique for curing a photocuring agent attached to the periphery of an intermediate connection portion of an electric wire or the like. Background technique [0002] Patent Document 1 discloses a technology for sealing off water at an intermediate connection portion connecting electric wires. In Patent Document 1, a waterproofing agent is supplied to the intermediate junction portion of electric wires, and the intermediate junction portion and the waterproofing agent supplied to the intermediate junction portion are covered with a sheet. After that, UV light from a UV (ultraviolet) light irradiation device is irradiated on the waterproofing agent through the sheet. Thus, the waterproofing agent is cured. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-80633 [0004] However, since UV light travels in a straight line, it is difficult to uniformly irradiate the entire periphery of the intermediate co...

AI Technical Summary

Problems solved by technology

[0004] However, since UV light travels in a straight line, it is difficult to uniformly irradiate the entire periphery of the intermediate connection portion with UV light.

Moreover, if there is a part where UV light is not sufficiently irradiated to the waterproofing agent around the intermediate joint, there is a possibility that there will be a site where the waterproofing agent is insufficiently cured around the intermediate joint.
