Abstract:
A bonding apparatus comprising:a position detection imaging device which images an object to be bonded from a side, a tool which is installed so as to be offset with respect to and imaged from said side by said position detection imaging device, and a reference member provided at a position and imaged from said side by said position detection imaging device, and said bonding apparatus further comprising: a light source which is disposed in a specified position and which projects a reference pattern toward said tool at a specified angle of inclination with respect to a measurement direction when a tip end of said tool is adjacent said reference member, and an operation control device that is configured to determine amount of offset between said position detection imaging device and said tool based upon: a measured value that is obtained when a position of said tool is measured based upon said reference pattern projected on said tool when said tin end of said tool is adjacent said reference member while being imaged by said position detection imaging device, and a measured value that is obtained when said position of said position detection imaging device is measured relative to said reference member while being imaged by said position detection imaging device.
