Title: ELECTRONIC COMPONENT INSERTION ASSEMBLY MACHINE
Abstract:
When a cut-and-clinch head (21) is lifted by a Z-axis drive device (24) from a stand-by position spaced apart downward from a lower surface of a circuit substrate (14) to an operation position for performing a cut-and-clinch operation, the cut-and-clinch head is high-speed lifted at a maximum speed in an interval from the stand-by position spaced apart downward from the lower surface of the circuit substrate to a deceleration start position, the lift speed of the cut-and-clinch head is reduced from the deceleration start position, and the cut-and-clinch head is stopped at the operation position where the cut-and-clinch operation is performed. In this case, in accordance with the amount of downward warping of the circuit substrate or information having correlation therewith, the height of the deceleration start position is modified. For example, control is provided to decrease the height of the deceleration start position as the amount of downward warping of the circuit substrate increases. In this way, regardless of the amount of downward warping of the circuit substrate, a proper deceleration distance between the deceleration start position and the lower surface of the circuit substrate can be stably ensured.
