An electric-component mounting system including a component-holding device for holding an electric component, a board-supporting device for supporting a printed-wiring board on which the electric component is mounted, a first relative-movement device operable to move the component-holding device and the board-supporting device relative to each other in a first direction parallel to a surface of the board supported by the board-supporting device, a second relative-movement device operable to move the component-holding device and the board-supporting device relative to each other in a second direction which intersects the surface of the board; and a control device including a positioning portion operable to select one of a plurality of different control targets which is used for the first relative-movement device to establish a predetermined relative position between the component-holding device and the board-supporting device, and wherein the positioning portion selects one of the different control targets, depending upon a pattern of control of an operating speed of the first relative-movement device.
摘要:
A mounting system for an electric component operates by transferring the electric component from a component supply device to a suction nozzle of a component-holding head on a circuit substrate. A relative position between a sucking surface of the suction nozzle and an axis of rotation of the component-holding head is obtained. A component-holding head and the component supply device are moved relative to each other on the basis of the obtained relative position, so as to minimize an error of relative positioning between the sucking surface and a predetermined sucking position of the electric component positioned at the component-supply portion. The head and the component supply device are then moved toward each other, for transferring the electronic components from the component supply device to the suction nozzle.

An electric-component mounting system wherein a determining device is operated for presently required operations of working devices disposed on a common main body, to determine a cycle-time-determinant working device which determines a cycle time of the system such that the cycle time is determined by a required operating time of the cycle-time-determinant working device as calculated when the presently required operation is performed at predetermined maximum acceleration and deceleration values or a predetermined maximum operating speed, and a slowdown device determines actual acceleration and deceleration values or an actual operating speed of each of non-cycle-time-determinant working device, so as to be lower than the predetermined maximum acceleration and deceleration values or operating speed thereof, such that the presently required operation of each non-cycle-time-determinant working device can be completed within the cycle time determined by the cycle-time-determinant working device.

Ease and scope of use of a substrate-related-operation performing apparatus are improved. The substrate-related-operation performing apparatus such as a component mounting apparatus employs an operation performing head 21 such as a mounting head 21, such that the operation performing head 21 is detachably attached to the apparatus. Preferably, a plurality of operation performing heads 21 having different constructions can be replaced with each other. In this case, each operation performing head 21 includes a recording medium 400 in which individual information of the head 21 is recorded, and the apparatus reads the individual information from the medium, recognizes (500), based on the read individual information, information related to the head 21, and prepares, based on the recognized head-related information, for using the head 21 attached to the apparatus. The apparatus can automatically prepare the use of the head 21, by judging (512) whether the head 21 can be used, selecting (516) a software driver corresponding to the head 21, and performing calibration of the head 21, i.e., adjustment of a position related to a movement of the head 21.
