（ステップ＃８）。In step # 1, the controller 8 drives the actuator 5 from the initial state to open and close the valve 4 to adsorb the component. At this time, the control device 8 grasps the open / closed state of the valve 4 in each suction nozzle. Next, in step # 2, the control device 8 retrieves a source pressure value Y corresponding to the number X of suction nozzles in the suction state as shown in Table 1 from the storage device inside the control device 8. In step # 3, the pressure sensor 3 inputs the value Z of the original pressure of the vacuum generation source 2 into the control device 8. Further, in step # 4, the relationship of Y−Z <δ (1) Y−Z ≧ δ (2) is compared using Y and Z and the allowable error δ, and the formula (1) is established. In this case, normal adsorption is determined (step # 5), and normal processing is continued (step # 6). Further, when the expression (2) is satisfied, it is determined that the suction is a mistake (step # 7) and the suction error processing is performed (step # 8).

ことができる。As is apparent from the description of the above embodiment, according to the component non-suction detection method of the present invention, the number of pressure sensors is reduced as much as possible in the rotary head type component mounter in which the mounting speed is increased. This makes it possible to detect unadsorbed parts by a low-cost and space-saving method regardless of the number of heads, prevent out-of-stock on the production substrate, and improve the reliability of the product. In addition, the reliability of the device itself can be improved by not providing the detection mechanism in the movable part. In addition, by minimizing the detection mechanism, equipment downtime due to factors such as sensor malfunction can be suppressed.
