Wire disconnection inspecting device and method
First Claim
1. A wire disconnection inspecting method comprising the steps of:
- connecting a terminal unit to an electronic control unit mounted on a vehicle;
detecting a preparation timing which is a prescribed distance and/or a prescribed time before said vehicle reaches a prescribed inspection position, for an inspection unit to start energizing a heater conductor on a glass panel of said vehicle through said terminal unit; and
when the arrival of said vehicle at the prescribed inspection position is detected, controlling said inspection unit to acquire a thermal image of said glass panel captured by an infrared camera and processing said thermal image to inspect said heater conductor for a wire disconnection.

Abstract
A wire disconnection inspecting device includes a vehicle position recognition unit for detecting that a vehicle has reached an inspection position; a preparation timing recognition unit for detecting that a step preceding by one is reached; a terminal for transmitting an operation signal to an ECU so as to make an electrical connection to a heating conductor; an infrared camera for imaging a rear shield of the vehicle; and a main processing unit for acquiring thermal image data from the infrared camera and inspecting disconnection of the heating conductor. The main processing unit recognizes that the vehicle has reached a step preceding by one according to the preparation timing recognition unit and makes electrical connection to the heating conductor via the terminal. The main processing unit acquires the image data from the infrared camera when the vehicle has reached the inspection position.

6. A wire disconnection inspecting device for inspecting a heater conductor on a glass panel of a vehicle after the vehicle has been assembled, comprising:
-
a vehicle position recognizing unit for detecting arrival of said vehicle at a prescribed inspection position; a preparation timing recognizing unit for detecting a preparation timing which is a prescribed distance and/or a prescribed time before said vehicle reaches said prescribed inspection position; a terminal unit, which is connected to an electronic control unit mounted on said vehicle for controlling energization of said heater conductor, for sending an operation signal to said electronic control unit to energize said heater conductor; an infrared camera for capturing an image of said glass panel of said vehicle which has reached said inspection position; and an inspection unit connected to said vehicle position recognizing unit, said preparation timing recognizing unit, and said terminal unit, for acquiring a thermal image from said infrared camera and inspecting said heater conductor for a wire disconnection based on said thermal image, wherein said inspection unit controls said terminal unit to start energizing said heater conductor when said preparation timing recognizing unit recognizes said preparation timing and acquires said thermal image from said infrared camera when said vehicle position recognizing unit recognizes the arrival of said vehicle at said inspection position. - View Dependent Claims (7)
