PROBLEM TO BE SOLVED: To provide a bonding device, which can prevent a bonding tool from being broken by the descent of the tool at a turn-off time of a power supply and at the time of non-current conduction, such as service interruption, and is stable in bondability and can reduce an irregularity in a loop shape. SOLUTION: A bonding device is constituted into such a structure that the device is provided with a swinging arm 1 having a bonding tool 2 on the point, a support material 5 having an axis 3 of rotation for supporting in such a way as to freely slide this swinging arm 1 and a motor which drives the arm 1, the arm 1 is provided with an electromagnet 21 and at the time of current conduction, a balancer 24 is magnetically sucked to the electromagnet 21 to keep the balance of the arm 1 and at the time of non-current conduction, the magnetic suction of the balancer 24 is released and the balancer 24 descends and the point side of the arm 1 is leapt up. |
