Abstract
A method of inspecting whether a printed board is appropriately supported by a supporting device, when a holding device holding an electric component mounts the electric component on the printed board supported by the supporting device, the method including the steps of taking, with an image taking device, an image of at least one prescribed detection portion of the printed board supported by the supporting device, and judging, based on image data representing the taken image of the detection portion, whether the printed board is appropriately supported by the supporting device.
Claims18
A method of inspecting whether a printed board is appropriately supported by a supporting device, when a holding device holding an electric component mounts the electric component on one of opposite surfaces of the printed board the other surface of which has at least one electric component already mounted thereon and is engaged with the supporting device, the supporting device including at least one support member having at least one two-dimensional support spot which supports the printed board by engaging said other surface thereof at at least one support location prescribed for a sort of the printed board, the method comprising the steps of:
- taking, with an image taking device, an image of at least one prescribed detection portion of said one surface the printed board said other surface of which is supported by the supporting device, and
- judging, based on image data representing the taken image of said at least one detection portion of said one surface of the printed board, whether said at least one electric component already mounted on said other surface of the printed board is interfered with by said at least one support member of the supporting device.
A method of inspecting whether a printed board is appropriately supported by a supporting device, when a holding device holding an electric component mounts the electric component on one of opposite surfaces of the printed board the other surface of which has at least one electric component already mounted thereon and is engaged with the supporting device, the supporting device including at least one support member having at least one two-dimensional support spot which supports the printed board by engaging said other surface thereof at at least one support location prescribed for a sort of the printed board, the method comprising the steps of:
- detecting a height position of at least one prescribed detection portion of said one surface of the printed board said other surface of which is supported by the supporting device, and
- judging, based on the detected height position of said at least one detection portion, whether said at least one electric component already mounted on said other surface of the printed board is interfered with by said at least one support member of the supporting device.
An apparatus for mounting at least one electric component on a printed board, comprising:
- a supporting device which supports the printed board by engaging a lower surface thereof that has at least one electric component already mounted thereon, the supporting device including at least one support member having at least one two-dimensional support spot which supports the printed board by engaging the lower surface thereof at at least one support location prescribed for a sort of the printed board;
- a holding device which holds the electric component and mounts the electric component on an upper surface of the printed board the lower surface of which is supported by the supporting device;
- an image taking device which takes an image of at least one detection portion of the upper surface of the printed board the lower surface of which is supported by the supporting device;
- and
- a control device which controls the supporting device, the holding device, and the image taking device to mount the electric component on the upper surface of the printed board,
- the control device comprising a judging portion which judges, based on image data representing the image of said at least one detection portion taken by the image taking device, whether said at least one electric component already mounted on the lower surface of the printed board is interfered with by said at least one support member of the supporting device.
A recording medium in which an inspecting program is recorded such that the inspecting program is readable by a computer to cooperate with an image taking device to inspect whether a printed board is appropriately supported by a supporting device in an electric-component mounting apparatus in which a holding device holding an electric component mounts the electric component on one of opposite surfaces of the printed board the other surface of which has at least one electric component already mounted thereon and is engaged with the supporting device, the supporting device including at least one support member having at least one two-dimensional support spot which supports the printed board by engaging said other surface thereof at at least one support location prescribed for a sort of the printed board at least one of the holding device holding the electric component and the supporting device supporting the printed board being movable relative to the other of the holding device and the supporting device, the inspecting program comprising the steps of:
- taking, with the image taking device, an image of at least one detection portion of said one surface of the printed board said other surface of which is supported by the supporting device, and
- judging, based on image data representing the taken image of said at least one detection portion of said one surface of the printed board, whether said at least one electric component already mounted on said other surface of the printed board is interfered with by said at least one support member of the supporting device.
