Abstract
Abstract An apparatus for carrying electronic components from a supply position to an electronic circuit board or the like and placing the electronic components on the electronic circuit board or the like, which has a rod provided at its tip end with a suction tool for picking up components to be carried and which is connected with an air suction apparatus; a body frame supporting the rod for movement of the rod in the vertical and horizontal directions; two pairs of position regulating pawls which are movably supported on the rod and are supported for freely opening and closing to grasp the components from different directions which the components are held by the suction tool and positioning them; and an arrangement for opening and closing the position regulating pawls.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
335 words
An apparatus for carrying and placing components, comprising: a body frame fixed at a position; a rod means movably supported on said body frame for movement in the vertical and horizontal directions; a moving means connected to said rod means for moving said rod means in the horizontal direction; a further moving means connected to said rod means for moving said rod means in the vertical direction; a suction tool on the lower end of said rod means for picking up a component; suction means connected to said suction tool for supplying a vacuum to said suction tool when the suction tool is carrying a component; at least one pair of positioning pawls rotatably mounted on said rod means and having free ends for grasping and positioning a component therebetween when the free ends are moved toward each other; and a means for rotating said positioning pawls in synchronization with the movement of said rod means and having a first spring connected between the pawls in each pair and urging the free ends of said pawls toward each other, a pawl supporting member slidable on said rod means, a second spring engaging said pawl supporting member and urging the pawl supporting members and pawls along said rod means in the axial direction thereof toward said suction tool, and at least one pin on said rod means and engaged by said pawls as said pawls move toward said suction tool for urging said pawls apart to move the free ends away from each other against the action of said first spring, whereby said pawls have the free ends apart when the suction tool on the rod means is in the lowered position for picking up or positioning a component, and when said rod means is moved to the raised position, said free ends are moved together by said first spring for engaging the free ends with a component picked up by said suction tool from opposite directions for properly positioning the component on said suction tool.
Claim 2
Independent Claim
335 words
An apparatus for carrying and placing components, comprising: a body frame fixed at a position; a rod means movably supported on said body frame for movement in the vertical and horizontal directions; a moving means connected to said rod means for moving said rod means in the horizontal direction; a further moving means connected to said rod means for moving said rod means in the vertical direction; a suction tool on the lower end of said rod means for picking up a component; suction means connected to said suction tool for supplying a vacuum to said suction tool when the suction tool is carrying a component; at least one pair of positioning pawls rotatably mounted on said rod means and having free ends for grasping and positioning a component therebetween when the free ends are moved toward each other; and a means for rotating said positioning pawls in synchronization with the movement of said rod means and having a first spring connected between the pawls in each pair and urging the free ends of said pawls toward each other, a pawl supporting member slidable on said rod means, a second spring engaging said pawl supporting member and urging the pawl supporting members and pawls along said rod means in the axial direction thereof toward said suction tool, and at least one pin on said rod means and engaged by said pawls as said pawls move toward said suction tool for urging said pawls apart to move the free ends away from each other against the action of said first spring, whereby said pawls have the free ends apart when the suction tool on the rod means is in the lowered position for picking up or positioning a component, and when said rod means is moved to the raised position, said free ends are moved together by said first spring for engaging the free ends with a component picked up by said suction tool from opposite directions for properly positioning the component on said suction tool.
Claim 3
Dependent Claim
44 words
An apparatus as claimed in claim 1 wherein there are two pairs of positioning pawls each rotatably mounted on said rod means and movable in directions for moving the free ends into engagement with a component held by said suction tool from different directions.
Claim 4
Dependent Claim
29 words
An apparatus as claimed in claim 2 wherein the respective pairs of pawls are mounted on said rod means for rotation around axes which are perpendicular to each other.
Claim 5
Dependent Claim
42 words
An apparatus as claimed in claim 1 further comprising a pair of electrodes, one on each of the positioning pawls, for detecting the presence of a component between said pawls by engagement of said electrodes with a component engaged by said pawls.
