An industrial robot of the horizontal multi-articulation type includes a vertical shaft providing an articulation between a first arm and a second arm. The shaft is supported for rotation at a fixed vertical position on the first arm while the second arm is removably secured through clamping to an end portion of the vertical shaft second arm which projects downwardly from the first arm. The bottom end of the shaft is supported by a removable bearing plate. A pulley operatively connected to a motor is mounted for rotation on the shaft, and a speed reduction gear is interposed between the pulley and the shaft so that the shaft and hence the second arm are angularly rotated by the motor at a very low speed relative to the speed of the motor. In this arrangement, the second arm can be easily mounted and removed on and from the shaft and hence the first arm.

Industrial robot

A simplified method of and apparatus for mounting an electronic part such as a transistor on a circuit board. Two or more selected ones of terminals of an electronic part are angularly bent in prior, and when the electronic part is to be mounted on a circuit board, the terminals are forcibly inserted into through-holes of the circuit board to an extent wherein bent portions of the terminals are projected below the circuit board. As a result, if a weak force is applied to pull the part off, the bent portions of the terminals will frictionally engage with edges of the through-holes to prevent the part from being removed from the board.
