Abstract
Abstract An apparatus for mounting electric parts on a printed circuit board, wherein the printed circuit board is transferred and is positioned and fixed at a predetermined position, includes a part mounting head for inserting 1 part into the printed circuit board and an anvil for bending the legs of the part inserted into the printed circuit board. The head and anvil are moved as a unit in a horizontal plane and they are movable between an independent separate supply section and the predetermined position for the printed circuit board.

Claim 1
Independent Claim
306 words
In an apparatus for mounting electric parts on a circuit board and of the type including a part supply section fixed to a base for supplying electric parts successively to a part supply position, a printed circuit board transfer section for supporting and transferring a printed circuit board, and a part mounting section for transferring parts between said part supply position and the printed circuit board, the improvement wherein: said part mounting section is positioned at a side of said printed circuit board transfer section opposite to a side thereof whereat said part supply section is positioned; and said part mounting section comprises a frame slidably mounted on a pair of horizontal guide shafts extending parallel to the printed circuit board transfer direction of said printed circuit board transfer section, upper and lower guide shafts respectively disposed at upper and lower portions of said frame so that they are slidable with said frame along said horizontal guide shafts and extend at right angles to said horizontal guide shafts with said horizontal guide shafts positioned between said upper and lower guide shafts, a connecting frame connecting said upper and lower guide shafts, a part mounting head mounted on said upper guide shaft, an anvil head mounted on said lower guide shaft, with said printed circuit board transfer section being positioned between said heads, a first motor for moving said frame along said horizontal guide shafts, and a second motor for moving said upper and lower guide shafts along said frame, said part mounting head comprising a chuck device for grasping electric parts, a shaft supporting said chuck device in a vertically movable and rotatable manner, a means to move said shaft vertically by compressed air, a means to rotate said shaft by compressed air, and a stop means to stop said shaft at a desired rotational position.

In an apparatus for mounting electric parts on a circuit board and of the type including a part supply section fixed to a base for supplying electric parts successively to a part supply position, a printed circuit board transfer section for supporting and transferring a printed circuit board, and a part mounting section for transferring parts between said part supply position and the printed circuit board, the improvement wherein: said part mounting section is positioned at a side of said printed circuit board transfer section opposite to a side thereof whereat said part supply section is positioned; and said part mounting section comprises a frame slidably mounted on a pair of horizontal guide shafts extending parallel to the printed circuit board transfer direction of said printed circuit board transfer section, upper and lower guide shafts respectively disposed at upper and lower portions of said frame so that they are slidable with said frame along said horizontal guide shafts and extend at right angles to said horizontal guide shafts with said horizontal guide shafts positioned between said upper and lower guide shafts, a connecting frame connecting said upper and lower guide shafts, a part mounting head mounted on said upper guide shaft, an anvil head mounted on said lower guide shaft, with said printed circuit board transfer section being positioned between said heads, a first motor for moving said frame along said horizontal guide shafts, and a second motor for moving said upper and lower guide shafts along said frame, said part mounting head comprising a chuck device for grasping electric parts, a shaft supporting said chuck device in a vertically movable and rotatable manner, a means to move said shaft vertically by compressed air, a means to rotate said shaft by compressed air, and a stop means to stop said shaft at a desired rotational position.
Claim 3
Dependent Claim
98 words
The improvement claimed in claim 1, wherein said part supply section comprises magazines adapted to be filled beforehand with electric parts to be supplied, a stock case holding said magazines in several rows, said stock case being inclined at an angle enabling said magazines to fall under their own weight, discharge lever means for, when the parts in the lowermost said magazine have been discharged, removing such magazine, an inclined chute extending continuously from a part outlet of said stock case, and a case for separating one by one the parts in a front end of said chute.
Claim 4
Dependent Claim
42 words
The improvement claimed in claim 1, wherein said means to rotate said shaft comprises a cylinder tube rotatable with said shaft and a valve member on said cylinder tube and rotatable by compressed air, thus rotating said cylinder tube and said shaft.
Claim 5
Dependent Claim
57 words
The improvement claimed in claim 3, wherein each said chuck device comprises two opposed chuck pawls capable of holding an electric part therebetween, a slide shaft vertically movable within said shaft, and links connected to said slide shaft and to said chuck pawls for opening and closing said chuck pawls upon vertical movement of said slide shaft.
Claim 6
Dependent Claim
88 words
The improvement claimed in claim 4, further comprising an opening in a peripheral portion of said slide shaft, a hole communicating with said opening and extending through said slide shaft radially thereof, a first pin engageable with said opening and constantly urged to contact said slide shaft, and a second pin slidably mounted in said hole and so arranged that it abuts against a fixed guide and thereby moved in said hole to abut against said first pin to thereby drive said first pin out of said opening.
