Abstract
Abstract There is herein described an improved surface mounted component (SMC) transport mechanism which accepts a multiple number of such components from a plurality of carrier media and transports them to a desired location, for example, adjacent a printed circuit board (PCB) prior to the mounting of the SMC onto the PCB.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
A random access surface mounted component transport system used in the population of surface mounted components (SMC) in printed circuit board (PCB) fabrication, including: an elongated movement mechanism including a multiple SMC carrier, said mechanism having a plurality of adjacent loading points and a downstream off-loading station, said movement mechanism including an overhead cam assembly including a bus-carried SMC-holding mechanism actuator, a different one of said actuators being disposed at each of said loading points; a plurality of adjacent SMC carrier media disposed adjacent said movement mechanism, each SMC carrier media associated with a different one of said loading points; loading means positioned adjacent said loading points and said SMC carrier media for moving selected SMC from said carrier media to said multiple SMC carrier of said movement mechanism for transportation of SMC to said off-loading station; unloading means position adjacent said off-loading station for moving SMC from said multiple SMC carrier to an appropriate position on a PCB in a predetermined sequence; and bus means for transporting said SMC, said bus means including a plurality of bus members temporarily attachable to said time belt upstream of said loading points and temporarily detachable from said time belt adjacent said off-loading station.
Claim 2
Dependent Claim
201 words
A random access surface mounted component transport system used in the population of surface mounted components (SMC) in printed circuit board (PCB) fabrication, including: an elongated movement mechanism including a multiple SMC carrier, said mechanism having a plurality of adjacent loading points and a downstream off-loading station, said movement mechanism including an overhead cam assembly including a bus-carried SMC-holding mechanism actuator, a different one of said actuators being disposed at each of said loading points; a plurality of adjacent SMC carrier media disposed adjacent said movement mechanism, each SMC carrier media associated with a different one of said loading points; loading means positioned adjacent said loading points and said SMC carrier media for moving selected SMC from said carrier media to said multiple SMC carrier of said movement mechanism for transportation of SMC to said off-loading station; unloading means position adjacent said off-loading station for moving SMC from said multiple SMC carrier to an appropriate position on a PCB in a predetermined sequence; and bus means for transporting said SMC, said bus means including a plurality of bus members temporarily attachable to said time belt upstream of said loading points and temporarily detachable from said time belt adjacent said off-loading station.
Claim 3
Dependent Claim
49 words
The random access surface mounted component transport system according to claim 1, wherein said movement mechanism includes a chute dimensioned to slidably support said bus members from said off-loading station to a position upstream of said loading points, when said bus members are not attached to said timing belt.
Claim 4
Dependent Claim
40 words
The random access surface mounted component transport system according to claim 2, wherein said movement means also includes return means for moving said bus members within said chute from said off-loading station to said position upstream of said loading points.
Claim 5
Dependent Claim
20 words
The random access surface mounted component transport system according to claim 3, wherein said return means is an air source.
Claim 6
Dependent Claim
58 words
The random access surface mounted component transport system according to claim 1, wherein said overhead cam assembly includes an elongated vacuum manifold through which each of said mechanism-actuators are disposed, each of said SMC-holding mechanisms including passages communicating with the vacuum environment within said vacuum manifold to extend said vacuum environment to said selected ones of said SMC.
Claim 7
Dependent Claim
27 words
The random access surface mounted component transport system according to claim 1, wherein each of said SMC-holding mechanism actuators is selectively actuated through a forked shift mechanism.
Claim 8
Dependent Claim
53 words
The random access surface mounted component transport system according to claim 6, wherein each of said forked shift mechanisms is slidably coupled to an associated cam of said overhead cam assembly and adapted to move said cam into and out of said cam's engagement with a selected one of said SMC-holding mechanism actuators.
Claim 9
Dependent Claim
23 words
The random access surface mounted component transport system according to claim 1, wherein said overhead cam assembly includes an elongated, cam-supporting cam shaft.
Claim 10
Dependent Claim
69 words
The random access surface mounted component transport system according to claim 1, wherein said unloading means includes an off-loader arm cooperating with each of said SMC-holding mechanisms, and includes an increment off-loader system adjacent said off-loader station and receiving said bus members as each detaches from said timing belt, said off-loader system incrementing said bus position to register a different one of said SMC-holding mechanisms with said off-loader arm.
