DOOR OPENING CLOSING DEVICE FOR AUTOMOBILE

摘要

PURPOSE:To improve the detecting capability of a non-contact type sensor and to insert an engaging rod into a glass groove without bringing it into contact with the painted surface of a door by shortening the distance between the non-contact type sensor and the upper edge of the door. CONSTITUTION:The non-contact type sensor 28 to detect the shape of the upper edge of the door 6 and the engaging rod 32 which is driven vertically by a cylinder 27 and can be inserted into the glass groove 7 of the door 6 are arranges respectively at the tip part of a robot arm 4. The tip part of this robot arm is moved horizontally toward the door 6 as the tip part of the robot arm is approached to a height of the upper edge of the door 6 as possible and when the sensor 28 detects a specified shape 9 making a mark at the upper edge of the door 6, the cylinder 27 is driven to insert the engaging rod 32 into the glass groove 7 of the door 6 and this robot arm is moved horizontally to open and close the door 6. In this manner, the detecting capability of the non-contact type sensor can be improved and the duration of service life of the sensor be expanded.
