Abstract:
1. An automatic disk feeding device for disk duplication system, comprising: a disc holder, two transport assemblies, a linkage rod and a power source, wherein: the transport assemblies are disposed at both sides of the disk holder; the linkage rod is disposed between the transport assemblies for providing a synchronous movement of the transport assemblies; the power source is used to provide an operation power to the transport assemblies; each transport assembly comprises a linkage disk, a connecting rod, a positioning cover, a sliding block, two push members and two slide rails; the linkage disk of each transport assembly is eccentrically provided with a first pivot portion and is connected to the linkage rod; both ends of the connecting rod are provided with a first pivot portion and a second pivot portion, respectively, the first pivot portion of the connecting rod is combined with the first pivot portion of the linkage disk; the positioning cover is defined with a guide hole and is disposed on the disk holder for restricting the sliding block, the push members and the slide rails of each transport assembly; the sliding block of each transport assembly is provided with a second pivot portion at an outer surface thereof and is defined with at least one slant pushing groove at both sides thereof, the slant pushing groove is obliquely lowered from outside toward inside thereof, the sliding block is disposed in the positioning cover, the second pivot portion of the sliding block is inserted in the guide hole of the positioning cover and is pivotally disposed in the second pivot portion of the connecting rod; an inner surface of each push member is provided with at least one pushing protrusion, an outer surface of each push member is provided with at least one guiding protrusion, one end of each push member is provided with a clamping member, the push members are located at both sides of the sliding block which is disposed in the positioning cover, the pushing protrusion of the push member is inserted in the pushing groove of the sliding block, the clamping members of the transport assemblies are extended into the disc holder; the slide rails are disposed at the outer surfaces of the push members inside the positioning cover and are fixed to the positioning cover, an inner surface of each slide rail is defined with at least one L-shaped track having a horizontal section toward outside thereof, a vertical section is upwardly extended from an inner side of the horizontal section, the L-shaped tracks are provided for insertion of the guiding protrusions of the push members; the linkage disk of the transport assembly drives the connecting rod to move, and then the connecting rod moves the sliding block and make it move in the guide hole of the positioning cover, the pushing protrusion of each push member moves in the pushing groove of the sliding block, the guiding protrusion of each push member moves in the horizontal section and the vertical section of each L-shaped track, when the guiding protrusion moves in the horizontal section, the clamping member performs a telescopic movement, when the guiding protrusion moves in the vertical section, the clamping member performs telescopic, and ascending and descending movements.
