Method of mounting component on to substrate in component mounting device and component mounting device

1. A method for assembling a component on a board in a component assembly apparatus, which is provided with a component transfer device that includes at least two holding claws, which grip a component, opening and closing control of which is performed by a driving device, and that assembles the component by gripping the component using the holding claws and moving the component to an assembly position of the board, which is positioned in a stop position, the method comprising:

a transfer pressing step that assembles a portion of the component that corresponds to a target gripping location of the component on the board by applying a pressing force toward a board side after moving the component above the assembly position in a state in which the target gripping location of the component is gripped by the holding claws; and

a pressing step that opens the holding claws to release gripping of the component, that moves each of the holding claws to respective portions of the component that correspond to pressing force positions which are predetermined positions that differ from positions at which the target gripping location is gripped after the transfer pressing step, and that assembles the portions of the component that respectively correspond to the pressing force positions of each holding claw on the board by applying a pressing force to the component toward the board side using each holding claw.

2. The method for assembling a component on a board in a component assembly apparatus according to claim 1 ,

wherein a plurality of pins, which protrude, or a plurality of positioning holes are provided on a lower surface of the component,

a plurality of positioning holes or a plurality of pins, which protrude, that mutually correspond to the respective plurality of pins, which protrude, or the plurality of positioning holes that are provided on the component, are provided on an upper surface of the board,

the transfer pressing step press-fits one of, or the plurality of pins, or one of, or the plurality of positioning holes of the component, which correspond to the target gripping location of the component by the holding claws, to the positioning holes, or the pins of the board that correspond to the one of, or the plurality of pins, or one of, or the plurality of positioning holes of the component, which correspond to the target gripping location, by applying a pressing force to the upper surface of the component as a result of lowering the component after moving the component to a predetermined position at which each pin or each positioning hole of the component is aligned with each positioning hole or each pin of the board in a state in which the component is gripped by the holding claws, and

the pressing step press-fits each pin, or each positioning hole of the component, which correspond to pressing force positions by the holding claws, to each positioning hole, or each pin of the board, which correspond to the pressing force positions, by applying a pressing force to the upper surface of the component as a result of lowering the component after performing positioning of the holding claws in predetermined positions that differ from the positions that correspond to the target gripping location by performing opening and closing control using the driving device after the transfer pressing step.

3. The method for assembling a component on a board in a component assembly apparatus according to claim 2 ,

wherein, in the transfer pressing step and the pressing step, the holding claws press-fit upper surface positions of the component that correspond to the pins or the positioning holes.

4. The method for assembling a component on a board in a component assembly apparatus according to claim 1 ,

wherein, in the transfer pressing step and the pressing step, the holding claws are capable of rotating in a horizontal direction.

5. The method for assembling a component on a board in a component assembly apparatus according to claim 1 ,

wherein the pressing step also rotates the holding claws by 90° after releasing the component and separates the holding claws from each other to move the claws to the pressing force positions located at opposite ends of the component.

6. A method for assembling a component on a board in a component assembly apparatus, which is provided with a component transfer device that includes at least two holding claws, which grip a component, opening and closing control of which is performed by a driving device, and that assembles the component by gripping the component using the holding claws and moving the component to an assembly position of the board, which is positioned in a stop position, the method comprising:

a transfer pressing step that assembles a portion of the component that corresponds to a target gripping location of the component on the board by applying a pressing force toward a board side after moving the component above the assembly position in a state in which the target gripping location of the component is gripped by the holding claws; and

a pressing step that assembles each portion of the component that corresponds to a pressing force position by each of the holding claws on the board by applying a pressing force to the component toward the board side using the holding claws, opening and closing control of which is performed by the driving device, and which are positioned in predetermined positions that differ from positions at which the target gripping location is gripped after the transfer pressing step,

wherein the component assembly apparatus is provided with two component transfer devices, which assemble the component on a single board by cooperating, and

the transfer pressing step is implemented by one component transfer device, and the pressing step is implemented by the other component transfer device.

7. A component assembly apparatus which is provided with a component transfer device that includes at least two holding claws, which grip a component, opening and closing control of which is performed by a driving device, and that assembles the component by gripping the component using the holding claws and moving the component to an assembly position of the board, which is positioned in a stop position, the component assembly apparatus comprising:

a transfer pressing section that assembles a portion of the component that corresponds to a target gripping location on the board by applying a pressing force toward a board side after moving the component above the assembly position in a state in which the target gripping location of the component is gripped by the holding claws; and

a pressing section that opens the holding claws to release gripping of the component, that moves each of the holding claws to respective portions of the component that correspond to pressing force positions which are predetermined positions that differ from positions that correspond to the target gripping location, and that assembles portions of the component that respectively correspond to the pressing force positions of each holding claw on the board by applying a pressing force to the component toward the board side using each holding claw.

8. The component assembly apparatus according to claim 7 ,

wherein the pressing section rotates the holding claws by 90° after releasing the component and separates the holding claws from each other to move the claws to the pressing force positions located at opposite ends of the component.
