Abstract

In a suction nozzle held on a mounting head of a component mounting machine, a nozzle section that sucks a component is swingably provided on a nozzle holder section of a the suction nozzle, and an orientation of the nozzle section is changed by 90° to a downward orientation or a lateral orientation by swinging the nozzle section. The component is sucked by the nozzle section from above in a state in which the orientation of the nozzle section of the suction nozzle is downward in a component suction operation, and the component is mounted on an object such as a circuit board in a state in which the orientation of the component sucked by the nozzle section is set to the lateral orientation by the nozzle section the orientation of which is changed by 90° to the lateral orientation by swinging the nozzle section in the component mounting operation.

First claim

1 . A suction nozzle which is held on a mounting head of a component mounting machine that sucks and mounts a supplied component to an object,
wherein a nozzle section that sucks the component is swingably provided on a nozzle holder section which is held on the mounting head, and an orientation of the nozzle section is changed by 90° to a downward orientation or a lateral orientation by swinging the nozzle section, and the nozzle section sucks the component from above in a state in which the orientation of the nozzle section is the downward orientation in a component suction operation, and the component is mounted on the object in a state in which the orientation of the component that is sucked by the nozzle section is set to the lateral orientation by the nozzle section the orientation of which is changed by 90° to the lateral orientation by swinging the nozzle section in the component mounting operation.

2 . The suction nozzle according to claim 1 , comprising:
at least one magnet which holds the nozzle section by magnetic force in the state of being set in the downward orientation and in the state of being set in the lateral orientation respectively.

3 . The suction nozzle according to claim 2 ,
wherein the magnet functions as a stopper which limits a swingable range of the nozzle section to 90°.

4 . The suction nozzle according to claim 1 ,
wherein the orientation of the nozzle section is caused to be changed by 90° by moving the nozzle section horizontally or downwardly while contacting the nozzle section on a nozzle orientation change member which is provided in the component mounting machine when the orientation of the nozzle section is caused to be changed by 90°.

5 . The suction nozzle according to claim 4 ,
wherein an elastically deformable buffer member is provided on a portion of the nozzle section on which the nozzle orientation change member contacts.

6 . The suction nozzle according to claim 1 ,
wherein the nozzle holder section is configured so as to support the nozzle section to be movable up and down, and has the biasing means which biases the nozzle section downwardly.

7 . The suction nozzle according to claim 1 ,
wherein a plurality of the nozzle sections are provided on the nozzle holder section, and one component is sucked using the plurality of nozzle sections.

8 . A component mounting machine which holds the suction nozzle according to claim 1 in the mounting head.

9 . A component mounting machine which holds the suction nozzle according to claim 4 in the mounting head, comprising:
movement means for moving the nozzle orientation change member,
wherein when the orientation of the nozzle section is caused to be changed by 90°, the nozzle orientation change member is moved by the movement means to a position where the nozzle orientation change member contacts the nozzle section, and the mounting head moves the nozzle section horizontally or downwardly while the mounting head contacts the nozzle section on the nozzle orientation change member, and after the orientation change is completed, the nozzle orientation change member is retreated by the movement means to a position where the nozzle orientation change member does not interfere with the suction nozzle.

10 . The component mounting machine according to claim 9 ,
wherein the plurality of suction nozzles are held on the mounting head, and the orientation of the nozzle sections of the plurality of suction nozzles are caused to be changed by 90° by moving the nozzle sections of the plurality of suction nozzles horizontally or downwardly by the mounting bead while the mounting head contacts the nozzle sections on the nozzle orientation changing member.

11 . The component mounting machine according to claim 8 , further comprising:
a camera which images a component which is sucked by the nozzle section from below; and image processing means for processing the image which is captured by the camera and recognizes the component, wherein the orientation of the nozzle section is changed by 90° to the lateral orientation so that the component is imaged by the camera from below in a state in which the orientation of the component which is sucked by the nozzle section is set in the lateral orientation, the amount of deviation of a component suction position of the nozzle section is calculated by processing the image using the image processing means, and a command value of a mounting position of the component is corrected according to the amount of deviation of the component suction position.

12 . The component mounting machine according to claim 8 ,
wherein component data in which dimension data of the component is included is registered in a database, and the amount of lowering of the suction nozzle in the component suction operation and the amount of lowering of the suction nozzle in the component mounting operation are calculated based on the dimension data of the component by acquiring the dimension data of the component sucked by the nozzle section from the database.
