Abstract: A solenoid coil unit is provided with a solenoid coil that is to be arranged in parallel with another solenoid coil with a predetermined gap in a separation direction orthogonal to a center axis direction; and a rod-shaped core around which the solenoid coil is wound and having a length longer than the length of the solenoid coil in the center axis direction. The rod-shaped core has a center portion around which the solenoid coil is wound and end portions located at both ends of the rod-shaped core and extending from both ends of the solenoid coil, the ratio of the length to the width of the center portion is 2 or more, and the length of the solenoid coil in the center axis direction is approximately twice the gap.

Abstract: A component mounting machine includes a head having multiple pickup members, a moving device for moving the head, at least one feeder, and a control device. The feeder is configured to receive correction values for sets of the multiple pickup members, set a target feeding amount for the number of sets based on the received correction values for the number of sets, and sequentially feed components for the number of sets in a predetermined direction with each set target feeding amount. The control device is configured to acquire a positional deviation amount of the multiple pickup members in the predetermined direction for each set, and transmit the correction values for the number of sets based on the acquired positional deviation amount for the number of sets to the feeder so that the feeder collectively receives the correction values for the number of sets at a predetermined timing.

Abstract: A service system and a server capable of increasing an operation rate of a production base are provided. The server acquires operation information of a component mounter in a mounting work from a host computer in the production base. The server generates analyzed result data obtained by analyzing the operation information based on the types of the manufacturers (component manufacturer and the package manufacturer) of electronic component and the package. The server transmits the generated analyzed result data to host computers in the other production bases.

Abstract: The motor control device is capable of driving control of the stepping motor with a pre-excitation that excites the stepping motor for a first time with a current lower than that during driving before starting or when starting driving the stepping motor, and a post-excitation that excites the stepping motor at a current lower than that during driving when stopping or after stopping the driving of the stepping motor for a second time, and is capable of continuing the post-excitation and the pre-excitation for a period of time shorter than the sum of the first time and the second time when the post-excitation at the previous stopping of driving of the stepping motor and the pre-excitation at the next starting of driving of the stepping motor are executed without passing through the non-excited state.
